The present invention provides a heat-clearing cup, referring to fig. 1 to 5, the heat-clearing cup 100 includes a heating cup 200 and a filtering cup 300, and in addition, the heat-clearing cup 100 may further include a heating base (not shown) for heating to supply power to the heating cup 200. Obviously, the heating base is not a necessary component, as the heating cup 200 may also be directly connected to a power source by a wire.

The heating cup 200 is provided with a heating module 210, and the heating film block 210 extends into the heating cup 200, so that the heating module 210 can heat water in the heating cup 200 when being electrified. The heating cup 200 includes a heating cup holder 220 and a heating cup body 230, one end of the heating cup body 230 is fixedly connected with the heating cup holder 220, the other end of the heating cup body 230 forms a heating cup opening 240, the heating module 210 can be arranged on the heating cup holder 220 and the heating cup body 230 or separately arranged on the heating cup holder 220 and the heating cup body 230, the position where the heating module 210 is arranged is not limited, and the heating module 210 can heat water in the heating cup 200 only by ensuring that the heating module 210 can heat the water.

The filter cup 300 is internally provided with a filter element 310, the filter cup 300 comprises a filter cup seat 320 and a filter cup body 330, one end of the filter cup body 330 is fixedly connected with the filter cup seat 320, the other end of the filter cup body 330 forms a filter cup mouth 340, and the filter cup seat 320 is provided with a water through hole 321 in a penetrating way. The filter element 310 may be fixedly installed on the filter cup body 330, or may be fixedly installed on the filter cup holder 320, or the filter element 310 is disposed on both the filter cup body 330 and the filter cup holder 320, where the position where the filter element 310 is disposed is not specifically limited, so long as it is ensured that water injected into the filter cup 300 can be filtered through the filter element 310, and finally flows out through the water through hole 321 on the filter cup holder 320.

The net heat cup 100 has three states, an idle state, a filtering state, and a heating state.

When the heat-clearing cup 100 is in an idle state, referring to fig. 4, the filter cup 300 and the heating cup 200 are fixedly connected, so that the heat-clearing cup 100 is convenient to store and carry; and at the same time, the problem that the filter cup 300 or the heating cup 200 is easy to lose due to the split arrangement of the filter cup 300 and the heating cup 200 can be avoided.

When the heat-purifying cup 100 is in the filtering state, please refer to fig. 5, the cup seat 320 of the filtering cup is abutted with the mouth 240 of the heating cup, at this time, after the water in the filtering cup 300 is filtered by the filter element 310 on the filtering cup 300 to form purified water, the purified water flows into the heating cup 200 through the water through hole 321 on the cup seat 320 of the filtering cup, and the heating cup 200 plays a role in containing the purified water when the heat-purifying cup 100 is in the filtering state, that is, the heating cup 200 serves as a container when the heat-purifying cup 100 is in the filtering state, so that a user is prevented from needing to search other containers to store the purified water when using the filtering cup 300, and the user is convenient to prepare the purified water.

When the net heat cup 100 is in a heating state, the heating module 210 on the heating cup 200 is powered on to heat the water in the heating cup 200, and the filter cup 300 can be separated from the heating cup 200 because the filter cup 300 is not active when the heating cup 200 heats the water. Of course, in order to avoid splashing when the water in the heating cup 200 boils, the filter cup holder 320 may be abutted against the heating cup mouth 240, so that the problem that the water in the heating cup 200 splashes due to boiling is effectively avoided.

Obviously, in order to quickly obtain hot water, the heating cup 200 may also heat when the net heat cup 100 is in the filtering state, i.e. the water in the filtering cup 300 is filtered and flows into the heating cup 200 to be heated, so that the waiting time of the user is shortened, and the user experience is improved.

The heating module 210 is provided on the heating cup 200 of the net heat cup 100, the filter element 310 is provided on the filter cup 300 of the net heat cup 100, the heating cup 200 can be used for heating water, and the filter cup 300 can be used for filtering water. This allows the net heat cup 100 to have both a heating function and a filtering function, thereby satisfying the needs of the user. Because the heating cup 200 and the filtering cup 300 can be assembled together or separated from each other, when the heating cup 200 and the filtering cup 300 are assembled together, the volume of the whole net heat cup 100 is reduced, and the net heat cup 100 is convenient to store and carry. When the heating cup 200 and the filter cup 300 are separated from each other, the heating cup 200 and the filter cup 300 can be used as water cups at the same time, and particularly when a user is outdoors, the heating cup 200 and the filter cup 300 of the net heat cup 100 can be used as water cups at the same time, thereby greatly facilitating the user. In addition, since the filter cup 300 and the heating cup 200 are not interfered with each other in function, the mutual influence of the filter cup 300 and the heating cup 200 in volume is small, so that the heating cup 200 can heat more water at one time and can store more hot water at the same time; also, for the filter bowl 300, more water can be filtered at a time by the filter bowl 300, thus avoiding the problem that the user needs to charge water back and forth into the filter bowl 300 due to the limited volume of the filter bowl 300. In addition, the filter cup 300 can be fixedly connected with the heating cup 200 when the heating cup 200 completes the heating operation, and a user can take the heating cup 200 by holding the filter cup 300, so that the problem that the user is scalded when taking the heating cup 200 due to the too high temperature of the heating cup 200 is avoided.

It should be noted that, when the heat-purifying cup 100 is in the idle state, the filter cup 300 and the heating cup 200 may be sleeved together or spliced together; of course, the filter cup 300 and the heating cup 200 may be connected together by a connecting member, and there is no specific limitation on how the filter cup 300 and the heating cup 200 are fixed.

In an embodiment of the present invention, referring to fig. 4, the heating cup 200 is accommodated in the filter cup 300 when the net heat cup 100 is in an idle state. Specifically, the filter cup 300 has an inner diameter that is greater than or equal to the outer diameter of the heater cup 200. Preferably, the filter cup 300 has an inner diameter that is slightly larger than the outer diameter of the heater cup 200. When the net heat cup 100 is in an idle state, the heating cup 200 can be received in the filter cup 300, i.e., the heating cup rim 240 can be inserted into the filter cup 300 from the filter cup rim 340, or the heating cup holder 220 can be inserted into the filter cup 300 from the filter cup rim 340. By means of the arrangement, the heating cup 200 and the filtering cup 300 are skillfully integrated, so that the volume of the net heat cup 100 in an idle state is reduced, and the carrying by a user is facilitated.

When the heating cup 200 is accommodated in the filter cup 300, if the heating cup rim 240 is inserted into the filter cup 300 from the filter cup rim 340, the heating cup rim 240 is prevented from being exposed, so that the problem that foreign matters enter the heating cup 200 is avoided, and the setting of the cup cover is omitted.

In addition, when the heating cup 200 completes the heating operation, the filter cup 300 can be sleeved on the outer side of the filter cup 200, and the user can take the heating cup 200 by holding the filter cup 300, so that the user is effectively prevented from being scalded by the high-temperature heating cup 200.

In order to prevent the heating cup 200 contained in the filter cup 300 from falling off from the filter cup 300, the heating cup 200 and the filter cup 300 may be fixedly connected by a tight fit, a threaded connection, a snap connection, or other connection methods, and the specific connection method for the heating cup 200 and the filter cup 300 is not particularly limited herein.

When the heating cup 200 and the filter cup 300 are connected in a tight fit manner, the outer diameter of the heating cup 200 is set to be larger than the inner diameter of the filter cup 300 when the heating cup 200 and the filter cup 300 are produced; that is, the inner diameter of the filter cup 300 is slightly larger than the outer diameter of the heating cup 200, so that when the heating cup 200 is inserted into the filter cup 300, a small force is applied to insert the heating cup 200 into the filter cup 300; and when the filter cup 300 or the heating cup 200 is used, the heating cup 200 and the filter cup 300 can be detached by applying a small external force, so that the assembly and the disassembly of the heating cup 200 and the filter cup 300 are convenient.

When the heating cup 200 is screwed with the filter cup 300, a threaded section is required to be provided on the inner surface of the filter cup body 330, and a threaded section is correspondingly provided on the outer surface of the heating cup body 230. When the net heat cup 100 is in an idle state, the heating cup 200 is inserted into the filter cup 300 and is fixedly connected with the filter cup 300 through a screw connection. Because threaded connection has advantages such as connect convenience, swiftly, firm to be convenient for on the one hand heating cup 200 fixedly accept in net hot cup 100, on the other hand can also avoid heating cup 200 to drop from filtering cup 300, and then avoided the loss of heating cup 200.

It should be noted that, the length of the thread segments provided on the filter cup body 330 and the heating cup body 230 is not required to be too long, so long as the thread segments on the filter cup body 330 and the thread segments on the heating cup body 230 are ensured to be screwed and fixed with the filter cup body 330 and the heating cup body 230 when the heating cup 200 is accommodated in the filter cup 300. By this arrangement, the length of the thread segments machined on the heating cup body 230 and the filter cup body 330 is reduced, thereby facilitating the improvement of the production efficiency of the heating cup 200 and the filter cup 300. In addition, the screw thread section is arranged on the outer surface of the heating cup 200, so that the heating cup 200 is convenient for a user to hold, and the problem that the outer surface of the heating cup 200 is too smooth to hold easily is avoided.

When the heating cup 200 and the filter cup 300 are fastened together, it is necessary to provide a protrusion (not shown) on the inner wall surface of the filter cup body 330 and an annular fastening portion (not shown) extending in the circumferential direction on the outer wall surface of the heating cup body 230. When the heating cup 200 is inserted into the filter cup 300, the annular buckling part and the convex part are mutually abutted and slightly deformed at the same time, so that the annular buckling part smoothly moves to one side of the convex part far away from the cup opening 340 of the filter cup through the convex part, and the convex part limits the annular buckling part at the moment so as to fix the heating cup 200 in the heating cup 200; when the filter cup 300 or the heating cup 200 is needed, only the heating cup 200 and the filter cup 300 need to be applied with force at the same time, so that the annular buckling part on the heating cup 200 presses the convex part on the filter cup body 330, and then the annular buckling part passes over the convex part and moves towards the direction close to the filter cup opening 340, and the annular buckling part is separated from the buckling table, so that the heating cup 200 is pulled out from the filter cup 300.

Of course, in order to facilitate accommodating the heating cup 200 in the filter cup 300, the outer diameter of the heating cup body 230 may be gradually reduced from the heating cup mouth 240 to the heating cup seat 220, that is, the heating cup body 230 is in a conical shape, a truncated cone shape or other shapes, so that on one hand, one end of the heating cup body 230 adjacent to the heating cup seat 220 can play a guiding role, thereby facilitating inserting the heating cup body 230 into the filter cup body 330; on the other hand, when the heating cup 230 is accommodated in the filter cup 300, only one end of the heating cup 230 adjacent to the heating cup rim 240 is fixedly connected with the filter cup rim 340, so that the contact area between the heating cup 200 and the filter cup 300 is reduced, and the abrasion between the heating cup 230 and the filter cup 320 is reduced.

In one embodiment of the present invention, filter cup 300 may also be received in heater cup 200 when net heat cup 100 is in an idle state. Specifically, the outer diameter of the filter cup 330 is set to be less than or equal to the inner diameter of the heating cup 230, and the outer diameter of the filter cup holder 320 is set to be greater than the inner diameter of the heating cup 230. Preferably, the inner diameter of the heating cup 230 is slightly larger than the outer diameter of the filter cup 330. When the net heat cup 100 is in an idle state, the filter cup 330 can be received within the heating cup 230 and the filter cup holder 320 can be positioned outside the heating cup 200. By the arrangement, on one hand, the whole volume of the net heat cup 100 is reduced, and the carrying by a user is facilitated; on the other hand, the filter cup body 330 is inserted into the heating cup 200, so that the problem that the cup in the filter cup 300 is dirty due to the external sundries entering the filter cup 300 when the net heat cup 100 is in an idle state can be avoided. In addition, the filter cup holder 320 is disposed outside the heating cup body 230, and the filter cup holder 320 can be used as a force receiving portion when the filter cup 300 is separated from the heating cup 200, so that the filter cup 300 and the heating cup 200 can be separated conveniently.

It should be noted that, the filter cup 300 may also serve as a cup cover, that is, when the heating cup 200 completes the heating operation, the filter cup 300 may be abutted to the heating cup 200, so that the heating cup 200 is sealed, and therefore, the dissipation of hot water heat in the heating cup 200 is reduced, and the heat preservation effect of the heating cup 200 is improved.

In one embodiment of the present invention, the filter cup holder 320 is removably coupled to either the heater cup holder 220 or the heater cup rim 240 when the net heat cup 100 is in an idle state. Specifically, if the filter cup holder 320 is detachably connected with the heating cup holder 220, only a plug hole needs to be formed in the filter cup holder 320 or the heating cup holder 220. When the heat-clearing cup 100 is in an idle state, the filter cup holder 320 is inserted into the insertion hole on the heating cup holder 220, or the heating cup holder 220 is inserted into the insertion hole on the filter cup holder 320, so that the detachable connection of the filter cup holder 320 and the heating cup holder 220 is realized, and the insertion has the advantages of convenience and quickness in disassembly and assembly, and the like, so that the filter cup 300 and the heating cup 200 are conveniently spliced.

If the filter cup holder 320 is detachably connected with the heating cup rim 240, the outer diameter of the filter cup holder 320 may be set smaller than or equal to the inner diameter of the heating cup rim 240, so that the filter cup holder 320 and the heating cup rim 240 can be plugged. Of course, a plug hole may be formed on the filter cup holder 320, and when the heat-clearing cup 100 is in the idle state, the heating cup opening 240 is plugged into the plug hole on the filter cup holder 320. By the arrangement, the filter cup seat 320 can be detachably connected with the heating cup mouth 240, so that the filter cup 300 and the heating cup 200 can be spliced conveniently.

Obviously, the filter cup rim 340 may also be detachably connected to the heating cup holder 220 or the heating cup rim 240 when the net heat cup 100 is in an idle state. Specifically, when the filter cup rim 340 is detachably connected with the heating cup holder 220, the outer diameter of the heating cup holder 220 may be set smaller than or equal to the inner diameter of the filter cup rim 340, so that the heating cup holder 220 and the heating cup rim 240 can be plugged. Of course, a plug hole may be formed on the heating cup holder 220, and when the net heat cup 100 is in the idle state, the filter cup opening 340 is plugged with the plug hole on the filter cup holder 320. By the arrangement, the detachable connection between the filter cup holder 320 and the heating cup mouth 240 can be realized, so that the filter cup 300 and the heating cup 200 can be spliced conveniently.

When the filter cup rim 340 is detachably connected with the heating cup rim 240, the outer diameter of the filter cup rim 340 may be set to be larger than the outer diameter of the heating cup rim 240, or the outer diameter of the filter cup rim 340 may be set to be smaller than the inner diameter of the heating cup rim 240. Thus, when the net heat cup 100 is in an idle state, the filter cup rim 340 can be in butt joint with the heating cup rim 240, so that the filter cup 300 and the heating cup 200 are spliced together, and the filter cup 300 and the heating cup 200 form a whole, thereby being convenient for carrying and storing the net heat cup 100. In addition, the filter cup rim 340 and the heating cup rim 240 are in butt joint with each other, so that the filter cup rim 340 and the heating cup rim 240 are both blocked, which is beneficial to ensuring the cleaning of the filter cup 300 and the heating cup 200, and avoiding the foreign matters from entering the filter cup 300 or the heating cup 200 to pollute the heating cup 200 and the filter cup 300.

In addition, in other embodiments of the present invention, when the heat-purifying cup 100 is in the idle state, the filter cup 300 and the heating cup 200 of the heat-purifying cup 100 may be connected by a connection member, and the connection member may be a ring gasket 400 (refer to fig. 2), a butterfly clip 400' (refer to fig. 7), or the like, which is not limited herein.

Specifically, in one embodiment of the present invention, the connector is an annular gasket 400 that is installed between the heating cup 230 and the filter cup 330 and is used to connect and secure the heating cup 230 and the filter cup 330. Specifically, referring to fig. 2, when the outer diameter of the heating cup 230 is smaller than or equal to the inner diameter of the filter cup 330, the annular gasket 400 is sleeved on the heating cup 230; when the clean heat cup 100 is in the idle state, the heating cup body 230 is accommodated in the filter cup body 330, and the annular gasket 400 mounted on the heating cup body 230 is accommodated in the filter cup 300 together, and the outer diameter of the heating cup body 230 is slightly smaller than the inner diameter of the filter cup body 330, so that the annular gasket 400 positioned between the heating cup body 230 and the filter cup body 330 is extruded to deform, so that the gap between the filter cup body 330 and the heating cup body 230 is filled, and the filter cup body 330 and the heating cup body 230 are connected and fixed.

In addition, the annular gasket 400 can also avoid direct contact between the heating cup body 230 and the filtering cup body 330, so that on one hand, the outer wall surface of the heating cup body 230 and the inner wall surface of the filtering cup body 330 are prevented from being scratched; on the other hand, the problem that the inner wall surface of the filter cup body 330 and the outer wall surface of the heating cup body 230 are collided and deformed in the carrying process of the heat purifying cup 100 is avoided.

It should be noted that, if the outer diameter of the filter cup 330 is smaller than or equal to the inner diameter of the heating cup 230, the annular gasket 400 is sleeved on the filter cup 330, and the specific process of fixing the filter cup 330 in the heating cup 230 through the annular gasket 400 can refer to the specific process of fixing the filter cup 330 in the heating cup 230 through the annular gasket 400, and the description thereof will not be repeated.

Further, referring to fig. 6, the outer wall surface of the heating cup 230 is concavely provided with a positioning groove 231 extending along the circumferential direction thereof, and correspondingly, the inner surface of the annular gasket 400 is convexly provided with a positioning rib 410 extending along the circumferential direction thereof. When the annular gasket 400 is sleeved on the heating cup body 230, the positioning ribs 410 on the annular gasket 400 are matched with the positioning grooves 231 on the heating cup body 230, so that the annular gasket 400 sleeved on the heating cup body 230 is connected with the heating cup body 230 more firmly; and when the heating cup 230 is accommodated in the filter cup 330, the annular gasket 400 can avoid displacement relative to the heating cup 230 when the annular gasket is subjected to friction force of the filter cup 330 under the cooperation of the positioning ribs 410 and the positioning grooves 231, so that the heating cup 230 can be connected and fixed with the filter cup 330.

Further, the heating cup body 230 has a first section 230a adjacent to the heating cup holder 220 and a second section 230b connected to the first section 230a and extending away from the heating cup holder 220, and the outer diameter of the first section 230a is smaller than the outer diameter of the second section 230b, so that a step is formed at the connection between the first section 230a and the second section 230 b; correspondingly, one side end of the annular gasket 400 is outwardly expanded to be arranged in a step shape.

When the annular gasket 400 is sleeved on the heating cup body 230, the end of the annular gasket 400 with larger aperture is sleeved outside the second section 230b of the heating cup body 230, and the end of the annular gasket 400 with smaller aperture is sleeved outside the first section 230a of the heating cup body 230, so that the annular gasket 400 is positioned and installed on the heating cup body 230 conveniently; on the other hand, the user can hold the heating cup 200 conveniently, that is, the user can hold the joint between the first section 230a and the second section 230b of the heating cup body 230, so that the problem that the user is easy to take off hands due to too smooth outer surface of the heating cup 200 is effectively avoided. In addition, the annular gasket 400 has a certain heat insulation effect, and when the heating cup 200 is used for heating, a user can also take and place the heating cup 200 by holding the annular gasket 400, so that the problem that the user is inconvenient to take and place the heating cup 200 or scalded due to the fact that the temperature of the heating cup body 230 is too high can be avoided.

When the heating cup 200 is accommodated in the filter cup 300, the first section 230a of the heating cup body 230 extends into the filter cup body 330 and is fixedly connected with the filter cup body 330 through the section with smaller aperture of the annular gasket 400, and the second section 230b of the heating cup body 230 is positioned outside the filter cup body 330, so that the heating cup 200 can be accommodated in the filter cup 300; and at the same time, when the heating cup 200 is taken out, a force may be applied to the second section 230b of the heating cup body 230 to separate the heating cup 200 and the filter cup 300 from each other, thus facilitating the taking out of the heating cup 200.

In addition, it should be noted that the outer diameter of the second section 230b may be set to be the same as the outer diameter of the filter cup 300, so that when the heating cup 200 is accommodated in the filter cup 300, the second section 230b of the heating cup body 230 and the filter cup body 230 are spliced together, and the outer shape of the net heat cup 100 is more attractive when the net heat cup is in an idle state.

Considering that the annular gasket 400 is relatively slid with respect to the inner wall surface of the filter bowl 330 when the heating bowl 200 is accommodated in the filter bowl 300, the outer surface of the annular gasket 400 is provided in a concavo-convex shape in order to increase friction between the annular gasket 400 and the inner wall surface of the filter bowl 330. Specifically, referring to fig. 6, the outer surface of the annular gasket 400 is provided with a plurality of ribs 420 extending along the circumferential direction thereof and arranged at intervals along the axial direction thereof, so that the outer surface of the annular gasket 400 is prevented from being too smooth, and the heating cup 200 cannot be fixedly accommodated in the filter cup 300.

When the heating cup 200 is accommodated in the filter cup 300, the annular gasket 400 sleeved on the heating cup body 230 and the filter cup body 330 slide relatively, and at this time, the plurality of raised strips 420 protruding from the outer surface of the annular gasket 400 are contacted with the inner wall surface of the filter cup body 330, so that the friction between the filter cup body 330 and the annular gasket 400 is increased. And the plurality of protruding strips 420 are extruded to deform when contacting the filter cup body 330 and are attached to the inner surface of the filter cup body 330, so that the contact area between each protruding strip 420 and the filter cup body 330 is increased, the friction force between the filter cup body 330 and the annular gasket 400 is increased, and the heating cup 200 can be more stably contained in the filter cup 300.

In one embodiment of the present invention, referring to fig. 7, the connector is a butterfly clip 400' for connecting and fixing the heating cup 200 and the filter cup 300 of the net heat cup 100. Specifically, the butterfly clip 400 ' includes a main body 410 ' and two clamping portions 420 ' connected and fixed to the main body 410 ', and the two clamping portions 420 ' are all arranged in an arc shape. When the net heat cup 100 is in an idle state, the heating cup 200 of the net heat cup 100 is clamped by the clamping part 420 ', and the filtering cup 300 of the net heat cup 100 is clamped by the other clamping part 420 ', so that when the net heat cup 100 is in an idle state, the heating cup 200 and the filtering cup 300 of the net heat cup 100 are connected into a whole through the butterfly clamp 400 ', thereby being beneficial to carrying of the net heat cup 100, and avoiding the problem that one of the filtering cup 300 and the heating cup 200 falls down when a user carries the net heat cup 100, and further affecting the user experience.

The clamping portion 420' may be a ring structure with a complete circle or a ring structure with a notch, which is not particularly limited herein. Preferably, the clamping portion 420 ' has a ring-shaped structure with a notch, so that the clamping portion 420 ' can clamp the heating cup 230 or the filtering cup 330 by elastic deformation of itself, and the clamping portion 420 ' can clamp the heating cup 230 or the filtering cup 330 more firmly.

Further, the main body 410 ' of the butterfly clip 400 ' is provided in a long shape, the two clamping portions 420 ' of the butterfly clip 400 ' are provided at intervals along the length direction of the main body 410 ', and the two clamping portions 420 ' are located on the same side of the main body 410 '. When the net heat cup 100 is in the idle state, one clamping part 420 'of the butterfly clamp 400' clamps the filter cup body 330, and the other clamping part 420 'of the butterfly clamp 400' clamps the heating cup body 230, so that the connection and fixation of the heating cup 200 and the filter cup 300 are realized. Because the main body portion 410 ' of the butterfly clip 400 ' is elongated, the heating cup 200 and the filter cup 300 are arranged along the length direction of the main body portion 410 ', which is beneficial to reducing the space occupied by the net heat cup 100 and further facilitating the carrying of the user.

Obviously, the connector may also be a sleeve, one end of which may be used to receive the filter cup 300 of the net heat cup 100, and one end of which may be used to receive the heater cup 200, so that the filter cup 300 and the heater cup 200 may be connected together by the sleeve, thereby facilitating storage and carrying by a user.

It should be noted that, when the heat-purifying cup 100 is in the filtering state, the filter cup holder 320 is in butt joint with the heating cup rim 240, that is, the filter cup holder 320 and the heating cup rim 240 may be detachably connected by other connection modes such as plugging, threaded connection, and snap connection, and the manner of connection is not specifically limited herein.

In an embodiment of the present invention, referring to fig. 10, the filter cup holder 320 and the heating cup opening 240 are connected and fixed in a plugging manner. Specifically, the aperture of the water through hole 321 on the filter cup holder 320 is enlarged to be greater than or equal to the outer diameter of the heating cup rim 240. Preferably, the diameter of the water through hole 321 on the filter cup holder 320 is enlarged to be slightly larger than the outer diameter of the heating cup rim 240. When the net heat cup 100 is in the filtering state, the filter cup 300 is placed above the heating cup 200, and the heating cup opening 240 is inserted into the water through hole 321 of the filter cup holder 320, so that the filter cup 300 can be stably placed above the heating cup 200. So configured, on the one hand, avoids the need to secure the filter bowl 300 by other tools or users when the net heat bowl 100 is used to make water; on the other hand, the heating cup 200 is used to support the filter bowl 300 and store purified water, so that the carrying of an additional container is omitted, the number of articles carried by a user is reduced, and the user can go out conveniently.

Further, in order to facilitate the insertion of the filter cup holder 320 into the heating cup mouth 240, an annular groove 322 is concavely provided on the end surface of the filter cup holder 320 facing away from the heating cup body 330. The setting of annular groove 322 makes the pore wall of limber 321 can produce deformation when receiving the extrusion, this just makes when heating cup rim of a cup 240 is pegged graft with limber 321, even if the external diameter of heating cup rim of a cup 240 is slightly greater than the internal diameter of limber 321, limber 321's pore wall can peg graft the cooperation with heating cup rim of a cup 240 through taking place elastic deformation, so not only be convenient for peg graft the cooperation of heating cup rim of a cup 240 and limber 321, the dimensional accuracy of heating cup rim of a cup 240 has still been reduced simultaneously, the dimensional accuracy of the mould that is used for producing heating cup 200 has also been reduced promptly, be favorable to saving manufacturing cost.

Further, in order to facilitate the plugging of the filter cup holder 320 with the heating cup rim 240, the heating cup rim 240 may be tapered, that is, the outer diameter of the heating cup rim 240 gradually decreases from the heating cup body 230 to a direction approaching the filter cup body 330. Therefore, the outer wall surface of the heating cup rim 240 is an inclined surface, and the inclined surface has a guiding function, so that the guiding function can be realized when the heating cup rim 240 is inserted into the water through hole 321 on the filter cup seat 320, and the filter cup seat 320 is convenient to be inserted into the heating cup rim 240.

Of course, the water through hole 321 may be a taper hole, that is, the aperture of the water through hole 321 may be gradually reduced from the filter cup holder 320 to the direction approaching the filter cup body 330. So set up for the pore wall of this limber 321 can play the effect of guide equally when heating cup rim of a cup 240 and limber 321 peg graft, and then have the grafting of being convenient for filter cup holder 320 and heating cup rim of a cup 240. And when the outer wall surface of the heating cup rim 240 is an inclined surface, the hole wall of the water through hole 321 can be tightly attached to the outer wall surface of the heating cup rim 240, so that the stability between the filtering cup seat 320 and the heating cup rim 240 is further enhanced, and the problem that the filtering cup 300 topples over due to the existence of a gap between the hole wall of the water through hole 321 and the outer wall surface of the heating cup rim 240 is avoided.

Further, in order to stabilize the connection between the filter cup holder 320 and the heating cup mouth 240, the wall of the water through hole 321 is concavely provided with an internal thread section; correspondingly, the outer wall surface of the heating cup rim 240 is provided with an external thread section. When the clean heat cup 100 is used for preparing clean water, the heating cup rim 240 rotates into the water through hole 321 of the filter cup seat 320, so that the external thread section on the heating cup rim 240 is in threaded connection with the internal thread section on the wall of the water through hole 321, and the heating cup 200 and the filter cup 300 are connected into a whole, thereby avoiding the problem that the filter cup 300 is toppled over from the heating cup 200 due to the unstable connection between the filter cup 300 and the heating cup 200.

Obviously, in order to connect and fix the heating cup mouth 240 and the filter cup holder 320, other manners may be adopted for connection and fixation. In other embodiments of the present invention, a fastening portion is provided on the wall of the water through hole 321, and a fastening portion is provided on the outer wall of the heating cup rim 240. When the heat-clearing cup 100 is in a filtering state, the heating cup rim 240 is inserted into the water through hole 321 of the filtering cup body 330, at this time, the buckling position on the hole wall of the water through hole 321 is buckled with the buckling part on the heating cup rim 240, so that the fixed connection of the filtering cup holder 320 and the heating cup rim 240 is realized, and further, the problem that the filtering cup 300 is inclined and fallen down from the heating cup 200 due to the fact that the filtering cup holder 320 and the heating cup rim 240 are not fixed firmly when the filtering cup 300 is arranged above the heating cup 200 is avoided. When the filtration is completed, only the heating cup 200 and the filtering cup 300 are required to be applied with force at the same time, the buckling part on the cup mouth 240 of the heating cup and the buckling position on the wall of the water through hole 321 can be tripped, and thus the filtering cup 300 and the heating cup 200 can be conveniently detached.

In addition, in other embodiments of the present invention, the outer diameter of the filter cup holder 320 can also be set smaller than the inner diameter of the heating cup rim 240. Preferably, the outer diameter of the filter cup holder 320 is set to be slightly smaller than the inner diameter of the heating cup rim 240. When the net heat cup 100 is in the filtering state, the filter cup 300 is placed over the heating cup 200 and the filter cup holder 320 is inserted into the heating cup rim 240, so that the filter cup 300 can be fixed to the heating cup 200. By such arrangement, the filter bowl 300 can produce clean water without any other parts or direct support by the user, thereby facilitating the use of the clean heat bowl 100 by the user.

Furthermore, in other embodiments of the present invention, a connector may also be used to removably connect filter bowl 300 and heater bowl 200 when net heat bowl 100 is in the filtered state. Specifically, the structure of the connector in the above embodiment may be referred to, that is, the connector is a butterfly clip 400 ', which has a main body portion 410' and two clamping portions 420 ', the main body portion 410' is linearly arranged, the two clamping portions 420 'are spaced apart along the length direction of the main body portion 410', and the two clamping portions 420 'are located on the same side of the main body portion 410'. When the net heat cup 100 is in the filtering state, one clamping part 420 'of the butterfly clamp 400' clamps the filter cup body 330 so that the filter cup 300 is fixedly connected with the clamping part 420 ', the other clamping part 420' of the butterfly clamp 400 'clamps the heating cup body 230 so that the heating cup 200 is fixedly connected with the clamping part 420', and the filter cup 300 is arranged above the heating cup 200, so that the heating cup 200 is arranged below the filter cup 300 and acts as a container when the filter cup 300 is used for preparing the purified water.

It should be noted that the connector may also be a sleeve, one end of which may be used to receive the cup body of the filter cup 300, and one end of which may be used to receive the heater cup rim 240, such that the heater cup 200 is positioned below the filter cup 300 and functions as a container when the filter cup 300 is used to produce purified water.

It should be noted that, the filter element 310 in the filter bowl 300 needs to be replaced after a period of use, in order to facilitate replacement of the filter element 310 of the filter bowl 300, in an embodiment of the present invention, the filter bowl 330 and the filter bowl holder 320 are detachably connected, and the filter element 310 is fixedly installed between the filter bowl 330 and the filter bowl holder 320, so that the filter element 310 can be removed when the filter bowl 330 and the filter bowl holder 320 are detached, which facilitates disassembly and assembly of the filter element 310, and thus facilitates replacement of the filter element 310 on the filter bowl 300.

It should be noted that the filter cup holder 320 and the filter cup body 330 may be detachably connected by various connection manners, such as plugging, fastening, screwing, and other connection manners, which are not limited herein.

In an embodiment of the present invention, the filter cup body 330 and the filter cup holder 320 are connected and fixed in a plugging manner. Specifically, referring to fig. 3, the end surface of the filter cup holder 320 adjacent to the filter cup body 330 is concavely provided with a slot 323 surrounding the water through hole 321; the end of the filter cup body 330 adjacent to the filter cup holder 320 is convexly provided with a plug-in portion 331 extending in the circumferential direction of the filter cup body 330.

When the filter cup body 330, the filter element 310 and the filter cup holder 320 are assembled, the filter element 310 is firstly placed on the filter cup holder 320 or the filter cup body 330, then the plug-in part 331 on the filter cup body 330 is plugged with the slot 323 on the filter cup holder 320, and when the plug-in part 331 on the filter cup 300 is plugged in place, the filter cup body 330 is fixedly connected with the filter cup holder 320. At the same time, the filter element 310 is fixedly mounted between the filter cup holder 320 and the filter cup 330 by being restrained by the filter cup holder 320 and the filter cup 330. Because the plugging has the advantage of convenient disassembly and assembly, the filter cup body 330 and the filter cup seat 320 are convenient to disassemble and assemble, and the filter element 310 is more convenient and rapid to disassemble and assemble, so that the filter element 310 of the filter cup 300 is convenient to replace.

Further, in order to make the connection between the filter cup holder 320 and the filter cup body 330 stronger, the outer wall surface of the insertion portion 331 is provided with an external thread section, and correspondingly, the wall of the slot 323 is provided with an internal thread section. When the filter cup body 330 and the filter cup holder 320 are assembled, the insertion portion 331 on the filter cup body 330 is inserted into the slot 323 in a screw mode, so that the external thread section on the insertion portion 331 is in threaded connection with the internal thread section on the slot wall of the slot 323, connection between the filter cup body 330 and the filter cup holder 320 is firmer, the stability of threaded connection is higher compared with that of insertion, and therefore, in the process that the filter cup 300 is carried by a user, the filter cup body 330 cannot fall off from the filter cup holder 320.

It is obvious that the filter cup holder 320 and the filter cup body 330 may be fixedly connected by other connection methods, for example, the filter cup holder 320 and the filter cup body 330 are fixedly connected by a snap connection method. Specifically, a boss is protruding on the outer wall of the plug-in portion 331, and a fastening hole is penetrating through the slot wall of the slot 323 far from the water through hole 321. When the filter cup body 330 is assembled with the filter cup holder 320, the insertion portion 331 of the filter cup body 330 is inserted into the insertion groove 323 of the filter cup holder 320, and at the same time, the boss is fastened into the fastening hole, so that the filter cup body 330 is fixedly connected with the filter cup holder 320. In order to detach the filter cup 330 from the filter cup holder 320, an external force is applied to the boss to separate the boss from the fastening hole, so that the filter cup 330 and the filter cup holder 320 can be detached.

Of course, the filter cup holder 320 and the filter cup 330 may be connected and fixed by other fixing methods, which are not listed herein, and any structure capable of detachably connecting the filter cup holder 320 and the filter cup 330 is within the scope of the present invention.

In order to ensure the speed of preparing the purified water by the filter bowl 300, the aperture of the water through hole 321 on the bowl seat 320 of the filter bowl is set to be equal to the outer diameter of the filter element 310, so that the speed of passing the water in the filter bowl 300 through the filter element 310 is ensured, and the speed of preparing the purified water by the filter bowl 300 is further ensured.

In order to more stably mount the filter element 310 between the filter bowl 330 and the filter bowl 320, in an embodiment of the present invention, referring to fig. 3 and 8, a first annular limiting plate 332 extending along a circumferential direction of the filter bowl 330 is protruded from an inner wall surface of the filter bowl 330 adjacent to the filter bowl 320, and preferably the first annular limiting plate 332 and the filter bowl 330 are disposed adjacent to an end surface of the filter bowl 320. The wall of the water through hole 321 is convexly provided with a second annular limiting plate 324 extending along the circumferential direction of the water through hole 321, and preferably, the second annular limiting plate 324 is flush with one end of the water through hole 321 adjacent to the filter cup body 330. The filter element 310 includes a housing 311 and a filter material filled in the housing 311, the housing 311 of the filter element 310 is formed by splicing an upper cover 3111 and a lower cover 3112, and an outer surface of the housing 311 is provided with a protruding annular overlap portion 3113 extending along a circumferential direction thereof. It should be noted that the annular overlap 3113 may be formed by folding the edge of the lower cover 3112 outwards, or may be formed by folding the edge of the upper cover 3111, or may be formed by welding an annular sheet structure to the upper cover 3111 or the lower cover 3112, and the manner in which the annular overlap 3113 is formed is not particularly limited.

When the filter bowl 330, the filter bowl seat 320 and the filter element 310 are assembled, the filter element 310 is first placed on the filter bowl seat 320, so that the annular overlap joint portion 3113 is attached to the second annular limiting plate 324, and at this time, the lower cover 3112 of the filter element 310 is accommodated in the water through hole 321; the filter bowl 300 is then connected to the filter bowl 330, with one side of the annular overlap 3113 being limited by the first annular limiting plate 332 and the other opposite side of the annular overlap 3113 being limited by the second annular limiting plate 324, and the upper cover 3111 of the filter cartridge 310 being positioned inside the first annular limiting plate 332. After filter bowl 330 is secured in connection with filter bowl seat 320, annular overlap 3113 is clamped by first annular stop plate 332 and second annular stop plate 324 such that filter element 310 is secured between filter bowl 330 and filter bowl seat 320; and when the annular overlap 3113 is clamped by the first annular limiting plate 332 and the second annular limiting plate 324, the annular overlap 3113 is respectively attached to the first annular limiting plate 332 and the second annular limiting plate 324, so that tightness between the filter element 310 and the filter cup holder 320 and tightness between the filter cup body 330 are ensured.

In view of the fact that the filter element 310 is not fixed when being placed on the filter bowl holder 320, that is, the filter element 310 can move relative to the filter bowl holder 320, in order to position the filter element 310 on the filter bowl holder 320, referring to fig. 8, an annular clamping plate 325 extending away from the wall of the water through hole 321 is disposed at a side end of the second annular limiting plate 324, which is away from the wall of the water through hole 321, and a first clamping portion 3112a is formed by projecting a lower cover 3112 of the filter element 310 in a direction opposite to the upper cover 3111, and an outer diameter of the first clamping portion 3112a is equal to an inner diameter of the annular clamping plate 325.

When the filter element 310 is mounted on the filter cup holder 320, the first clamping portion 3112a of the lower cover 3112 is clamped and fixed with the annular clamping plate 325, and since the end portion of the annular clamping plate 325 away from the second annular limiting plate 324 is free, the annular clamping plate 325 can generate certain deformation when being extruded, so that the annular clamping plate 325 can be better matched with the first clamping portion 3112a of the lower cover 3112 in a clamping manner. And annular overlap 3113 of filter element 310 engages second annular stop plate 324 on filter bowl base 320, thus enabling quick positioning of filter element 310 to filter bowl base 320; and simultaneously, the filter element 310 fixedly mounted on the filter cup holder 320 cannot displace relative to the filter cup holder 320 due to the action of external force, so that the filter cup holder 320 and the filter cup body 330 can be assembled conveniently.

Obviously, in order to make the filter element 310 more firmly fixed to the filter cup holder 320, the first fastening portion 3112a and the annular fastening plate 325 may be fixedly connected by other connection methods such as a snap connection, a threaded connection, etc., so that the filter element 310 can be more firmly mounted to the filter cup holder 320.

In order to facilitate positioning between the filter element 310 and the filter bowl 330, referring to fig. 3 and 8, a second engagement portion 3111a is provided on the upper cover 3111 of the filter element 310 in a protruding manner away from the lower cover 3112. When the filter cup body 330 is fixedly connected with the filter cup holder 320, the second clamping portion 3111a is fixedly clamped with the first annular limiting plate 332, so that the filter element 310 is more stably installed between the filter cup body 330 and the filter cup holder 320. In addition, the second clamping portion 3111a on the upper cover 3111 is clamped with the first annular limiting plate 332, so that a seal can be formed between the upper cover 3111 and the first annular limiting plate 332; in addition, the annular overlap portion 3113 of the filter element 310 is attached to the first annular limiting plate 332 to form another seal, so that two seals are formed between the filter element 310 and the filter cup 330, and the two seals are arranged in an included angle, so that the risk of leakage of raw water in the filter cup 330 is reduced, and the tightness of the filter cup 300 is improved.

To further enhance the sealing of the filter bowl 300, a sealing structure is provided between the annular overlap 3113 and the first annular stop plate 332 and/or the second annular stop plate 324. That is, the sealing structure may be provided on the surface of the annular overlap portion 3113 facing the first annular stopper plate 332 or the surface of the annular overlap portion 3113 facing the second annular stopper plate 324, or may be provided on both the surface of the annular overlap portion 3113 facing the first annular stopper plate 332 and the surface of the annular overlap portion 3113 facing the second annular stopper plate 324, and the specific position where the sealing structure is provided is not particularly limited.

When the filter element 310, the filter cup holder 320 and the filter cup body 330 are assembled, the annular overlap portion 3113 is mounted between the first annular limiting plate 332 and the second annular limiting plate 324 in a limiting manner, and the annular overlap portion 3113 is connected with the first annular limiting plate 332 and the second annular limiting plate 324 in a sealing manner through sealing structures, so that tightness between the filter element 310 and the filter cup holder 320 and tightness between the filter cup body 330 are guaranteed.

In an embodiment of the present invention, the sealing structure is disposed on the annular overlap portion 3113, specifically, referring to fig. 9, a surface of the annular overlap portion 3113 facing the first annular limiting plate 332 and/or a surface of the annular overlap portion 3113 facing the second annular limiting plate 324 are each provided with a sealing rib 3114 extending along a circumferential direction of the annular overlap portion 3113, and the sealing rib 3114 forms the sealing structure. Preferably, a sealing rib 3114 is provided on both the surface of the annular overlap 3113 facing the first annular stopper 332 and the surface of the annular overlap 3113 facing the second annular stopper 324, the sealing rib 3114 constituting the above-described sealing structure.

When the filter element 310, the filter cup holder 320 and the filter cup holder 330 are assembled, the annular overlap portion 3113 is mounted between the first annular limiting plate 332 and the second annular limiting plate 324 in a limiting manner, and is clamped by the first annular limiting plate 332 and the second annular limiting plate 324 when the filter cup holder 320 is fixedly connected with the filter cup holder 330, at this time, the sealing ribs 3114 on the surface of the annular overlap portion 3113 facing the first annular limiting plate 332 are compressed by the first annular limiting plate 332 to deform, so that the annular overlap portion 3113 and the first annular limiting plate 332 form a seal, the sealing ribs 3114 on the surface of the annular overlap portion 3113 facing the second annular limiting plate 324 are compressed by the second annular limiting plate 324 to deform, so that another seal is formed between the annular overlap portion 3113 and the first annular limiting plate 332 and the second annular limiting plate 324, the sealing performance between the filter element 310 and the filter cup 300 is better, and water in the filter cup 300 cannot flow out of a gap between the filter element 300 and the filter cup 300 is ensured.

Of course, in order to secure sealability between the annular overlap portion 3113 and the first annular stopper plate 332 and the second annular stopper plate 324, a plurality of sealing ribs 3114 may be provided on a surface of the annular overlap portion 3113 facing the first annular stopper plate 332 and a surface of the annular overlap portion 3113 facing the second annular stopper plate 324, and the plurality of sealing ribs 3114 may be provided at inner and outer intervals in a radial direction of the annular overlap portion 3113. The number of the seal ribs 3114 may be set as required, and the number of the seal ribs 3114 is not particularly limited.

When the filter cup body 330 is fixedly connected with the filter cup holder 320, the annular overlap portion 3113 is clamped by the first annular limiting plate 332 and the second annular limiting plate 324, at this time, the plurality of sealing ribs 3114 on the surface of the annular overlap portion 3113 facing the first annular limiting plate 332 are compressed by the first annular limiting plate 332 to deform, the plurality of sealing ribs 3114 on the surface of the annular overlap portion 3113 facing the second annular limiting plate 324 are compressed by the second annular limiting plate 324 to deform, and thus a plurality of seals are formed between the annular overlap portion 3113 and the first annular limiting plate 332 and the second annular limiting plate 324, and as the seals between the annular overlap portion 3113 and the first annular limiting plate 332 and the second annular limiting plate 324 are increased, the tightness between the annular overlap portion 3113 and the first limiting plate and the second limiting plate is improved, and the tightness between the filter element 310 and the filter cup 300 is improved.

It should be noted that, if the height of the sealing rib 3114 is too high, when the first annular limiting plate 332 and the second annular limiting plate 324 clamp the annular overlap portion 3113, the sealing rib 3114 cannot be flattened, and the first annular limiting plate 332 and the second annular limiting plate 324 cannot be tightly attached to the annular overlap portion 3113, so that a problem of unstable installation of the filter element 310 occurs; if the height of the sealing rib 3114 is too small, the sealing rib 3114 will not deform when the first annular limiting plate 332 and the second annular limiting plate 324 clamp the annular overlap portion 3113, and thus the sealing effect between the annular overlap portion 3113 and the first annular limiting plate 332 and the second annular limiting plate 324 will be poor. In order to avoid the above problem, in an embodiment of the present invention, the height of the seal bar 3114 is defined to be 0.3 to 0.5mm. So set up, can produce deformation when guaranteeing that sealing bar 3114 receives the extrusion on the one hand, on the other hand can also guarantee that sealing bar 3114 can be flattened by first annular limiting plate 332 and second annular limiting plate 324 to when having guaranteed annular overlap joint portion 3113 by first annular limiting plate 332 and second annular limiting plate 324 centre gripping, sealing bar 3114 on the annular overlap joint portion 3113 can be flattened, and then has guaranteed the leakproofness between annular overlap joint portion 3113 and first annular limiting plate 332 and the second annular limiting plate 324.

Further, in order to enable the sealing rib 3114 to better seal the annular overlap portion 3113 with the first annular limiting plate 332 and the second annular limiting plate 324, the width of the sealing rib 3114 in the axial direction of the annular overlap portion 3113 is gradually reduced in a direction away from the annular overlap portion 3113; i.e., the sealing rib 3114 is triangular, trapezoidal or otherwise shaped in axial cross-section along the annular overlap 3113, in embodiments of the invention the sealing rib 3114 is preferably triangular in axial cross-section along the annular overlap 3113. When the sealing rib 3114 is in contact with the first annular limiting plate 332 and the second annular limiting plate 324, the contact area between the sealing rib 3114 and the first annular limiting plate 332 and the second annular limiting plate 324 is smaller, so that the stress of the side end of the sealing rib 3114, which is far away from the annular overlap joint portion 3113, is concentrated, and the sealing rib 3114 can be rapidly deformed when being clamped by the first annular limiting plate 332 and the second annular limiting plate 324, and further, the sealing rib 3114 can be flattened by the first annular limiting plate 332 and the second annular limiting plate 324, namely, the sealing rib 3114 can be in sealing connection with the annular overlap joint portion 3113 and the first annular limiting plate 332 and the second annular limiting plate 324.

The seal rib 3114 and the annular overlap portion 3113 are integrally formed, that is, are manufactured and formed by a mold, so that the sealing property between the seal rib 3114 and the annular overlap portion 3113 is ensured. And this sealing rib 3114 and annular overlap 3113 all adopt plastics to make, because plastics have better deformability, just so can produce great deformation when having guaranteed sealing rib 3114 pressurized, and when first annular limiting plate 332 and second annular limiting plate 324 are with sealing rib 3114 pressure flat, first annular limiting plate 332 and second annular limiting plate 324 respectively with annular overlap 3113 butt, and when first annular limiting plate 332 and second annular limiting plate 324 press from both sides annular overlap 3113 tight, this annular overlap 3113 still can produce deformation, just so guaranteed the leakproofness between annular overlap 3113 and first annular limiting plate 332 and the second annular limiting plate 324.

Considering that the molding difficulty of the triangular sealing rib 3114 is relatively high, in an embodiment of the present invention, the side end of the sealing rib 3114 far from the annular overlap portion 3113 is rounded, and compared with the side end of the sealing rib 3114 far from the annular overlap portion 3113 being provided with a sharp corner, the side end of the sealing rib 3114 far from the annular overlap portion 3113 is rounded, so that the mold is more convenient to open, and the manufacturing of the sealing rib 3114 is facilitated.

It should be noted that, the water through hole 321 on the cup seat 320 of the filter cup is not provided with a switch, so that when the filter cup 300 is filled with water, water flows into the water through hole 321 and flows out of the water through hole 321 through the filter element 310, which is inconvenient for a user. In view of the above, in an embodiment of the present invention, referring to fig. 8, an elastic switch 350 is provided on the filter cup holder 320, and the elastic switch 350 is used to control the opening/closing of the water through hole 321. This avoids the problem of water flowing out of the filter cup holder 320 during filling of the filter cup 300. When the clean heat cup 100 is in the filtering state, the filter cup seat 320 is in butt joint with the heating cup rim 240, and at this time, the elastic switch 350 is opened under the butt joint of the heating cup rim 240, so that the water filtered by the filter element 310 in the filter cup 300 flows into the heating cup 200 through the water through hole 321.

The elastic switch 350 may or may not have elasticity, and is not specifically limited herein, as long as the elastic switch 350 can seal the water through hole 321 on the filter cup holder 320 when the filter cup 300 is in the idle state, and can open the water through hole 321 when the elastic switch 350 is abutted.

In addition, it should be noted that when the filter cup 300 is not filled with water and the filter cup holder 320 is in butt joint with the heating cup rim 240, the elastic switch 350 is in butt joint with the heating cup rim 240, and at this time, the elastic switch 350 can open the water through hole 321 under the action of gravity of the filter cup 300, so that it is ensured that the water in the filter cup 300 can be discharged after being filtered by the filter element 310.

Considering that the aperture ratio of the water through hole 321 is large, if the elastic switch 350 is directly used to block the water through hole 321, the volume of the elastic switch 350 needs to be designed to be relatively large, in order to reduce the volume of the elastic switch 350, in an embodiment of the invention, referring to fig. 8, a baffle 326 is disposed at a side end of the annular clamping plate 325 away from the first annular limiting plate 332, the baffle 326 seals a side end of the annular clamping plate 325 away from the first annular limiting plate 332, and the baffle 326 is provided with a through hole 3261 in a penetrating manner, at this time, the baffle 326 and the annular clamping plate 325 are enclosed together to form a clamping groove, and a first clamping portion 3112a on the lower cover 3112 of the filter element 310 is clamped with a groove wall of the clamping groove and is disposed at a spacing from the baffle 326.

The elastic switch 350 includes a piston rod 351, a piston 352 provided at one end of the piston rod 351, and an abutting portion 353 provided at the other end of the piston rod 351.

When the elastic switch 350 is assembled with the filter cup holder 320, the piston rod 351 passes through the through hole 3261 and is in clearance fit with the through hole 3261, the piston 352 is connected to an end portion of the piston rod 351 located between the baffle 326 and the first engagement portion 311a, and the abutment portion 353 is connected to an end portion of the piston rod 351 remote from the filter element 310. It should be noted that at least one of the piston 352 and the abutment 353 is removably coupled to the piston rod 351, thereby facilitating the mounting of the resilient switch 350 to the filter cup holder 320.

When the heat-purifying cup 100 is in the idle state, referring to fig. 10, the piston 352 seals the through hole 3261 on the baffle 326 under the action of its own gravity, so that even if the filter cup 300 is filled with water, and the water flows into the clamping groove formed by the annular clamping plate 325 and the baffle 326 through the filter element 310, the water will not leak out from the through hole 3261 on the baffle 326, thereby facilitating the use of the filter cup 300 by a user. When the net heat cup 100 is in the filtering state, the filter cup holder 320 is abutted with the heating cup opening 240, preferably the filter cup holder 320 is sleeved on the heating cup opening 240, the abutting part 353 of the elastic switch 350 abuts against the heating cup opening 240 to be limited when the filter cup holder 320 is not completely sleeved on the heating cup opening 240, so that when the filter cup holder 320 is completely sleeved on the heating cup opening 240, the piston rod 351 connected with the abutting part 353 moves away from the heating cup 200, the piston 352 at the end part of the piston rod 351 close to the filter element 310 moves together with the piston rod 351, the piston 352 and the baffle 326 are separated from each other, the through hole 3261 on the baffle 326 is opened, and purified water filtered by the filter element 310 can flow into the heating cup 200 through the through hole 3261.

Further, the elastic switch 350 further includes an elastic member 354, one end of the elastic member 354 abuts against the abutting portion 353, and the other end of the elastic member 354 abuts against a surface of the baffle 326 opposite to the filter element 310. It is understood that the elastic member 354 may be a coil spring, a spring plate, etc., and is not particularly limited herein. In the embodiment of the present invention, the elastic member 354 is preferably a coil spring, which is sleeved on the piston rod 351, and one end of the coil spring is abutted against the abutment 353, and the other end of the coil spring is abutted against the baffle 326.

When the net heat cup 100 is in a filtering state, the filter cup seat 320 is sleeved on the heating cup rim 240, and when the filter cup seat 320 is not completely sleeved on the heating cup rim 240, the filter cup seat 320 contacts with the heating cup rim 240 and is limited by the heating cup rim 240; when the filter cup holder 320 is completely sleeved on the heating cup rim, the abutting part 353 is limited by the heating cup rim 240, so that the piston rod 351 connected with the abutting part 353 can only move away from the heating cup rim 240, and further the piston 352 connected with the end part of the piston rod 351 adjacent to the filter element 310 is separated from the baffle 326, and at the moment, the through hole 3261 on the baffle 326 is opened; at this time, the coil spring sleeved on the piston rod 351 is compressed; when the preparation of the purified water is finished, the filter cup holder 320 and the heating cup mouth 240 are separated from each other, at this time, the abutting part 353 is not limited, and the spiral spring restores the elastic deformation under the action of the self elastic force, so that the piston rod 351 moves in the direction away from the filter element 310, the piston 352 positioned at one end of the piston rod 351 close to the filter element 310 moves along with the piston rod 351, and moves in the direction close to the baffle 326 until the through hole 3261 on the baffle 326 is blocked, thereby ensuring that the filter cup 300 does not filter, and the filter cup holder 320 does not leak water, thereby facilitating the use of the filter cup 300 by a user.

It should be noted that, the maximum elastic force of the coil spring is smaller than the gravity of the whole filter cup 300, so that the elastic switch 350 can also open the water through hole 321 when the filter cup 300 in the empty cup state is docked with the heating cup 200.

In order to avoid the abutting portion 353 from affecting the abutting between the filter cup holder 320 and the heating cup rim 240, the length of the abutting portion 353 is set to be smaller than half of the inner diameter of the heating cup rim 240, and the inner wall surface of the heating cup rim 240 is provided with a limit protrusion 241 (see fig. 2). When the filter cup holder 320 is in butt joint with the heating cup rim 240, the abutting portion 353 extends into the heating cup rim 240 and abuts against the limiting protrusion 241, so that the filter cup holder 320 can be completely in butt joint with the heating cup rim 240.

Because the piston rod 351 is in clearance fit with the through hole 3261, if the stress direction of the piston rod 351 is not parallel to the axial direction of the through hole 3261, the moving piston rod 351 and the wall of the through hole 3261 are contacted with each other, so that the piston rod 351 is affected by the wall of the through hole 3261 and cannot slide smoothly, even the elastic switch 350 fails, that is, when the filter cup holder 320 is abutted with the heating cup rim 240, the elastic switch 350 cannot open the through hole 3261 on the baffle 326. In order to avoid the above problem, in an embodiment of the present invention, the abutting portion 353 is configured in a ring shape, that is, the abutting portion 353 is formed by extending the end of the piston rod 351 away from the baffle 326 towards the circumferential direction thereof, and the abutting portion 353 is hollowed out to form a plurality of holes for passing the purified water; correspondingly, the limiting boss 241 protruding on the inner wall surface of the cup mouth 240 of the heating cup is also in an annular shape. So when the abutting part 353 abuts against the limiting protrusion 241, the stress of the piston rod 351 in all directions is balanced, so that the stress direction of the piston rod 351 is ensured to be axially parallel to the through hole 3261, the piston rod 351 can move along the axial direction of the through hole 3261, and the elastic switch 350 can open the through hole 3261; meanwhile, the mutual contact between the piston rod 351 and the wall of the through hole 3261 is avoided, so that the problem that the piston rod 351 is worn is avoided, the service life of the piston rod 351 is guaranteed, and the service life of the elastic switch 350 is guaranteed.

When the filter bowl 300 and the heating bowl 200 are in the separated state, the abutting portion 353 is flush with the end surface of the filter bowl seat 320 away from the filter bowl 330, and the vertical distance between the piston 352 and the filter element 310 is H; and the vertical distance between the limiting protrusion 241 of the heating cup rim 240 and the end of the heating cup body 230 near the heating cup rim 240 is H, and H > H is set. When the filter cup holder 320 is sleeved on the heating cup rim 240, the filter cup holder 320 is abutted against the end part of the heating cup body 230, which is close to the heating cup rim 240, the piston 352 is jacked up by the piston rod 351 and is in a static state after moving H, at this time, the through hole 3261 on the baffle 326 is opened, and due to H > H, a certain gap is reserved between the piston 352 and the filter element 310, so that the problems that the filter element 310 is in direct contact with the piston 352, and the piston 352 is deformed by abutting and even is damaged are avoided.

Further, the baffle 326 is concavely provided in a direction away from the filter element 310 and is provided in a funnel shape; through holes 3261 penetrate through baffle 326 and the position of filter element 310 with the greatest vertical distance, so that purified water filtered by filter element 310 flows to through holes 3261 along the surface of baffle 326 facing filter element 310, and the purified water can be discharged rapidly. In addition, the baffle 326 is recessed away from the filter element 310, which also ensures a spacing between the filter element 310 and the piston 352, and thus also prevents the piston 352 from affecting the proper operation of the filter element 310.

When the net heat cup 100 is in a heating state, the heating cup 200 and the filter cup 300 are in a separated state, i.e., the heating cup 200 exists as a single heating container, and the heating cup 200 is further provided with a controller (not shown) electrically connected with the heating module 210, and a user controls the heating module 210 to operate through the controller, so that the user can conveniently obtain hot water through the heating cup 200.

Since the heating cup 230 is generally made of metal materials, and when the heating module 210 heats the water in the heating cup 200, the heating cup 230 may be heated, so that the temperature of the heating cup 230 is relatively high, and if a user directly takes the heating cup 230 when the heating cup 200 completes the heating operation, the user may be scalded by the heating cup 230 in a high temperature state. In order to avoid scalding the user by the heating cup 230, referring to fig. 2, in an embodiment of the invention, the heating module 210 is mounted on the heating cup holder 220, and the heating module 210 and the heating cup holder 220 are arranged at a distance, and meanwhile, the heating module 210 and the heating cup 230 are also arranged at a distance. This makes the heating module 210 not directly heat the heating cup holder 220 and the heating cup body 230 when heating the water in the heating cup 200, thereby avoiding the problem that the user is scalded due to the too high temperature of the heating cup 200.

Specifically, the end surface of the heating cup holder 220 adjacent to the heating cup body 230 is concavely provided with an annular mounting groove 221 surrounding the heating module 210; the heating cup body 230 is provided with an annular abutment 232 at an end adjacent the heating cup holder 220. When the heating cup holder 220, the heating module 210 and the heating cup body 230 are assembled, the heating module 210 is fixedly installed at one end of the heating cup holder 220 adjacent to the heating cup body 230, the annular butt joint part 232 on the heating cup body 230 is fixedly inserted into the annular mounting groove 221 on the heating cup holder 220, and the annular mounting groove 221 is arranged with the heating module 210, namely, the annular mounting groove 221 and the heating module 210 are arranged at intervals in the radial direction of the heating cup holder 220, so that the heating module 210 and the heating cup body 230 are skillfully arranged at intervals, the problem that the heating cup body 230 is heated when the heating module 210 works is avoided, and a user can directly take the heating cup 200 by hand when the heating cup 200 is ensured to finish heating work.

Further, referring to fig. 11, the heating cup holder 220 is provided with a mounting hole 222 therethrough, and the mounting hole 222 has a first mounting section 222a adjacent to the heating cup 230 and a second mounting section 222b communicating with the first mounting section 222a and far from the filtering cup 330, wherein the aperture of the first mounting section 222a is smaller than that of the second mounting section 222 b.

The heating cup 200 further includes a first base plate 250 and an annular fixing plate 255, the annular fixing plate 255 being mounted in the first mounting section 222a, the first base plate 250 being mounted in the second mounting section 222a and an edge of the first base plate 250 abutting a junction of the first and second mounting sections 222a, 222 b.

When the heating module 210 is assembled with the heating cup holder 220, the heating module 210 is mounted in the first mounting section 222a of the mounting hole 222 and abuts against the surface of the annular fixing plate 255 facing away from the first bottom plate 250, and the heating module 210 is also fixedly connected with the first bottom plate 250 by a fastener, so that the heating module 210 is fixed into the mounting hole 222. Because the heating module 210 is only contacted with the annular fixing plate 255, heat generated during operation of the heating module is reduced from being conducted to the heating cup holder 220 and the heating cup body 230, and further the problem that the user is scalded due to overhigh overall temperature of the heating cup 200 is effectively avoided.

Preferably, the fastening member is a screw (not shown), the surface of the first bottom plate 250 facing the heating module 210 is convexly provided with a first mounting post 251, and the end surface of the first mounting post 251 away from the first bottom plate 250 is concavely provided with a threaded hole penetrating the first bottom plate 250; correspondingly, the surface of the heating module 210 facing the first bottom plate 250 is convexly provided with a second mounting column 213, and the end surface of the second mounting column 213 far away from the heating module 210 is concavely provided with a threaded hole, and a screw penetrates through the first mounting column 251 from the side of the first bottom plate 250 facing away from the heating module 210 to be in threaded connection with the second mounting column 213, so that the first mounting column 251 and the second mounting column 213 are fixedly connected. Since the heating module 210 does not penetrate through the hole, it is ensured that no water leakage occurs in the heating module 210, and since the screw is not in direct contact with the heating module 210, heat loss generated during operation of the heating module 210 is reduced, and thus, the working efficiency of the heating module 210 is improved.

To facilitate positioning between the heating module 210 and the annular fixing plate 255, the annular fixing plate 255 is provided with a first annular connection plate 255a connected to the inner wall surface of the first mounting section 222a and extending along the circumferential direction of the first mounting section 222a, a second annular connection plate 255b extending from the first annular connection plate 255a in a direction away from the heating cup 230, and a third annular connection plate 255c extending from the second annular connection plate 255b in a direction away from the inner wall surface of the first mounting section 222 a; this causes the first annular connection plate 255a, the second annular connection plate 255b, and the third annular connection plate 255c to be disposed zigzag in the axial cross section of the mounting hole 222. Correspondingly, the side surfaces of the heating module 210 are correspondingly arranged in a zigzag shape, that is, the heating module 210 has a first heating portion 211 with a larger diameter and a second heating portion 212 with a smaller diameter, and a step is formed at the connection between the first heating portion 211 and the second heating portion 212, so that the side surfaces of the heating module 210 are arranged in a zigzag shape. When the heating module 210 is fixedly mounted on the heating cup holder 220, the second heating portion 212 of the heating module 210 extends into the third annular connecting plate 255c and is fixedly inserted into the third annular connecting plate 255c; the first heating portion 211 of the heating module 210 extends into the second annular connecting plate 255b and is fixedly inserted into the second annular connecting plate 255b, and a portion of the first heating portion 211 laterally beyond the second heating portion 212 abuts against the third annular connecting plate 255c, so that the heating module 210 is quickly mounted on the heating cup holder 220.

It should be noted that, since the second annular connecting plate 255b and the third annular connecting plate 255c are not in contact with the wall of the mounting hole 222, if the heat generated by the heating module 210 during operation is to be conducted to the heating cup body 230, the heat needs to be conducted to the heating cup seat 220 through the first annular connecting plate 255a, then conducted to the heating cup body 230 through the heating cup seat 220, and the heat conducted to the heating cup seat 220 through the first annular connecting plate 255a is limited, so that it is ensured that the heat cannot be conducted to the heating cup body 230 during operation of the heating module 210, and therefore, the temperature of the heating cup body 230 is not too high, and a user is convenient to take the heating cup 200.

In addition, since the second annular connecting plate 255b and the third annular connecting plate 255c are not in contact with the wall of the mounting hole 222, that is, the second annular connecting plate 255b and the third annular connecting plate 255c can deform when being stressed, when the second heating portion 212 of the heating module 210 extends into the inner side of the third annular connecting plate 255c, even if the diameter of the second heating portion 212 of the heating module 210 is slightly larger than the inner diameter of the third annular connecting plate 255c, the third annular connecting plate 255c can be in plug-in fit with the second heating portion 212 of the heating module 210 through deformation, so that the second heating portion 212 of the heating module 210 can be conveniently matched with the third annular connecting plate 255 c. Similarly, when the diameter of the first heating portion 211 of the heating module 210 is greater than the inner diameter of the second annular connection plate 255b, the second annular connection plate 255b may also be engaged with the first heating portion 211 of the heating module 210 by being deformed. This facilitates the positioning and mounting of the heating module 210 to the heating cup holder 220.

In order to avoid the excessive temperature of the heating cup 230, referring to fig. 12, an insulating cavity 233 extending along the circumferential direction of the heating cup 230 may be further provided on the heating cup 230. Because the heating cup body 230 is generally made of a metal material, the heat conduction performance of the metal material is far better than that of air, that is, the heat insulation cavity 233 arranged on the heating cup body 230 can effectively relieve the problem that the heating cup body 230 is too high in temperature and further the user is scalded due to the fact that the high-temperature hot water conducts heat to the outer wall surface of the heating cup body 230. Meanwhile, the heat insulation cavity 233 can also effectively prevent heat loss of the high-temperature hot water in the heating cup 200, so that the heat insulation effect of the hot water cup is improved.

Further, in order to improve the heat insulation effect of the heat insulation cavity 233, the heat insulation cavity 233 can be vacuumized, and as no conducting medium exists in the heat insulation cavity 233, the heat of the high-temperature hot water in the heating cup 200 is difficult to conduct to the outer wall surface of the heating cup body 230, so that on one hand, the temperature of the heating cup body 230 is ensured not to rise along with the rise of the water temperature, and the user is convenient to take the heating cup 200; on the other hand, the heat preservation effect of the heating cup 200 is improved, and the user experience is improved.

Obviously, in order to enhance the heat insulation effect of the heat insulation cavity 233, the heat insulation cavity 233 may be filled with a heat insulation material, which may be glass fiber, asbestos, rock wool, silicate, or the like, and the heat insulation material is not particularly limited herein. The arrangement of the heat insulation material can prevent the heat of the high-temperature hot water in the heating cup 200 from being conducted to the outer wall surface of the heating cup body 230, so that on one hand, the temperature of the heating cup body 230 is ensured not to rise along with the rise of the water temperature, and a user can conveniently take the heating cup 200; on the other hand, the heat preservation effect of the heating cup 200 is improved, and the user experience is improved.

Considering that when the heating module 210 is mounted on the heating cup holder 220, a gap exists between the heating module 210 and the heating cup holder 220, which affects the overall sealability of the heating cup 200, in order to improve sealability between the heating module 210 and the heating cup holder 220, in an embodiment of the present invention, a first sealing ring 260 is disposed between the heating module 210 and the second annular connecting plate 255b, and the first sealing ring 260 is mounted between the first heating portion 211 and the second annular connecting plate 255b of the heating module 210 and closely contacts the first heating portion 211 and the second annular connecting plate 255b of the heating module 210. The arrangement of the first sealing ring 260 not only improves the sealing between the heating module 210 and the heating cup seat 220, but also has the heat insulation effect, that is, the heat generated during the operation of the heating module 210 is blocked by the first sealing ring 260 and cannot be quickly transferred to the first annular connecting plate 255a, so that the temperature of the heating cup body 230 is further ensured not to be too high.

Further, referring to fig. 11, both the surface of the second annular connecting plate 255b abutting against the first sealing ring 260 and the surface of the heating module 210 abutting against the first sealing ring 260 are provided in a concave-convex shape, when the first sealing ring 260 is fixedly installed between the second annular connecting plate 255b and the heating module 210, the first sealing ring 260 is pressed by the second annular connecting plate 255b and the heating module 210 to deform and tightly adhere to the heating module 210 and the second annular connecting plate 255b, so that the first sealing ring 260, the second annular connecting plate 255b and the heating module 210 directly form a plurality of seals, and if water in the heating cup 200 flows out through a gap between the heating module 210 and the first sealing ring 260 or a gap between the second annular connecting plate 255b and the first sealing ring 260, the plurality of seals need to be overcome, so that the difficulty of water leakage in the heating cup 200 is increased, and the overall sealing performance of the heating cup 200 is improved.

In order to facilitate the user to obtain hot water with different temperatures, referring to fig. 11, the heating cup 200 is further provided with a temperature sensor 270, and the temperature sensor 270 is electrically connected to the controller of the heating cup 200 and is fixedly installed in the heating cup 200. Preferably, the temperature sensor 270 is fixedly mounted to the heating module 210 and extends into the heating cup 200. The user may set a target temperature through the controller, and when the temperature sensor 270 detects that the water temperature in the heating cup 200 reaches the target temperature, the controller may control the heating module 210 to stop operating, i.e., control the heating module 210 to be powered off. By such arrangement, the user can obtain different temperatures conveniently, and the problem that the heating cup 200 can only provide boiling water for the user is avoided.

Further, the heating cup 200 is further provided with a reminding device (not shown) electrically connected to the controller, and the reminding device may be a red flash lamp, a buzzer or other devices with alarm function, which is not limited herein. When the temperature sensor 270 detects that the water temperature in the heating cup 200 reaches the target temperature, the controller controls the reminding device to work so as to remind the user that the water temperature in the heating cup 200 reaches the target temperature, so that the problem that the temperature of the hot water in the heating cup 200 is reduced due to the fact that the user does not take the hot water in the heating cup 200 in time is avoided, and further, the water in the heating cup 200 needs to be heated again, and unnecessary waste of energy is caused.

In order to facilitate connection between the heating module 210 and the power source, in an embodiment of the invention, referring to fig. 11, a connector 280 electrically connected to the heating module 210 is further disposed on the heating cup holder 220, and specifically, the connector 280 is fixedly mounted in the second mounting section 222b of the mounting hole 222. It should be noted that, the connector 280 is used with the heating base, and when the heating cup 200 works, the heating cup 200 is only required to be placed on the seat of the heating cup 200, so that the connector 280 is in butt joint with the heating base, and thus the heating module 210 can be communicated with the power supply.

Because the connector 280 is exposed on the end surface of the heating cup holder 220 away from the heating cup body 230, when the heating cup 200 is cleaned, water easily flows into the first mounting section 222a of the mounting hole 222 from the gap between the first bottom plate 250 and the wall of the mounting hole 222, thereby affecting the normal operation of other components mounted in the first mounting section 222a and electrically connected with the heating module 210. In an embodiment of the present invention, a waterproof glue is injected into the second mounting section 222b of the mounting hole 222, and the waterproof glue fills the gap between the connector 280 and the second mounting section 222b, so that the end of the heating cup holder 220, which is far away from the heating cup body 230, is also sealed, and therefore, when the heating cup 200 is cleaned on the whole body, water cannot flow into the first mounting section 222a of the mounting hole 222 from the gap between the first bottom plate 250 and the mounting hole 222, and further, it is ensured that other components mounted in the first mounting section 222a and electrically connected with the heating module 210 can work normally.

In order to facilitate the arrangement of the wires, the first bottom plate 250 is provided with a wire through hole 252 in a penetrating manner, the wires electrically connected with the heating module 210 pass through the wire through hole 252 to be electrically connected with the connector 280, and the wire through hole 252 is sealed under the plugging of waterproof glue. This ensures that the second mounting section 222b of the mounting hole 222 is completely blocked from the first mounting section 222a of the mounting hole 222.

Further, in order to enable the waterproof glue to better plug the via hole 252, the first bottom plate 250 is recessed opposite to the surface of the heating module 210 and is configured as an arc surface, and the via hole 252 penetrates through the arc surface to be closest to the heating module 210. When the waterproof glue is poured into the second mounting section 222b of the mounting hole 222, the heating cup holder 220 is inverted, at this time, the wire passing hole 252 on the first bottom plate 250 is located at the lowest position of the first bottom plate 250, the waterproof glue poured into the second mounting section 222b of the mounting hole 222 flows along the first bottom plate 250 towards the wire passing hole 252, so that the wire passing hole 252 is ensured to be blocked by the waterproof glue, and water is ensured not to enter between the first bottom plate 250 and the heating module 210 through the wire passing hole 252 when the heating cup 200 is cleaned, so that parts arranged between the heating module 210 and the first bottom plate 250 are ensured not to be affected by water all the time, namely, the heating cup 200 is ensured to be cleaned by water as a whole.

Obviously, in order to make the waterproof glue capable of better plugging the via hole 252, other technical means may be adopted, for example, a wire loop (not shown) is sleeved on the wire, and the wire loop is tightly matched with the via hole 252, so that the hole of the via hole 252 is greatly reduced, and a large amount of waterproof glue is prevented from flowing into the first section 230a of the mounting hole 222, and normal operation of other parts is further affected. The wire harness ring is made of plastic, rubber or other materials with good elasticity, in this embodiment, the wire harness ring is preferably made of rubber with good deformation capability, when the wire harness ring fixes the wire into the wire through hole 252, the wire harness ring can stirrup the wire through the elastic deformation capability of the wire harness ring, and the wire through hole 252 is tightly matched with the wire through hole 252 through the elastic deformation capability of the wire harness ring, and the waterproof glue poured into the second mounting section 222b of the mounting hole 222 can seal the gap between the wire harness ring and the wire and the gap between the wire harness ring and the wire through hole 252, so that the wire through hole 252 can be sealed well.

In order to facilitate the installation of the connector 280, in an embodiment of the present invention, a surface of the first bottom plate 250 facing the connector 280 is convexly provided with a plurality of mounting tables 253, the connector 280 is correspondingly provided with a plurality of mounting tabs 281, and each mounting tab 281 is fixedly mounted on one mounting table 253 through a fastener; and the height of each mounting table 253 is greater than the vertical distance from the end of the connector 280 adjacent to the first base plate 250 to each mounting tab 281, such that the connector 280 is spaced from the first base plate 250. So configured, on the one hand, it is convenient to fixedly mount the connector 280 to the heating cup holder 220; on the other hand, the connector 280 can be prevented from affecting the flow of the waterproof glue, so that the waterproof glue can seal the wire passing hole 252 on the first bottom plate 250 and the gap between the first bottom plate 250 and the second section 230b of the mounting hole 222, the tightness of the heating cup holder 220 is improved, the tightness of the whole heating cup 200 is improved, and the situation that water enters the heating cup holder 220 when the heating cup 200 is cleaned and a safety accident occurs to the heating cup 200 in the subsequent use is avoided.

Further, the heating cup 200 further comprises a second bottom plate 285, and the second bottom plate 285 is further provided with a relief hole 2851 therethrough. When the second bottom plate 285 is fixedly attached to the end of the heating cup base 220 remote from the heating cup body 230, the connector 280 emerges from the relief hole 2851 of the second bottom plate 285. By the arrangement, the waterproof glue filled in the second section 230b of the mounting hole 222 is prevented from being exposed outside, so that the problem that the sealing effect of the waterproof glue is invalid due to the influence of other external factors is effectively avoided.

Considering that the connector 280 on the heating cup holder 220 is still exposed when the heating cup 200 is not heated, the connector 280 is easily stained with dust or other foreign matters, and normal electrical conduction of the connector 280 is affected. In order to avoid the above problems, in an embodiment of the present invention, the heating cup 200 is further provided with a cover 290 for covering the connector 280, that is, when the heating cup 200 is in an idle state, the cover 290 is in a closed state, and the connector 280 mounted on the cup holder 220 of the heating cup is covered by the cover 290, so that the connector 280 is prevented from being exposed to the outside, and the connector 280 is prevented from being stained with dust or other foreign matters, thereby ensuring that the connector 280 can conduct electricity normally; when the heating cup 200 is in the heating state, the cover 290 is in the open state, so that the connector 280 is exposed, and the connector 280 is electrically connected with the heating base conveniently.

It should be noted that, the cover 290 and the heating cup holder 220 may be connected or separated. In an embodiment of the present invention, the cover 290 is separately disposed from the filter cup holder 320, and the cover 290 is fixedly connected to the filter cup holder 320 through a magnetic assembly. Specifically, the edge of the heating cup holder 220 away from the heating cup body 230 is provided with a metal wrapping (not shown), and the edge of the cover 290 is correspondingly provided with a magnetic attraction piece (not shown). When the cover plate 290 covers the connector 280, the magnetic attraction piece on the cover plate 290 is fixedly connected with the metal wrapping edge on the heating cup seat 220 through magnetic attraction, so that the problem that the cover plate 290 falls off from the heating cup seat 220 is avoided; when the heating cup 200 needs to be used, the cover plate 290 can be removed by applying a small force to the cover plate 290, and the removed cover plate 290 can be fixed to the heating cup body 230 through the magnetic adsorption capacity of the magnetic attraction piece because the heating cup body 230 is made of a metal material, so that the problem that the cover plate 290 is easy to be lost due to independent placement is avoided.

In addition, since the end of the heating cup holder 220 far away from the heating cup body 230 is used for bearing the weight of the whole heating cup 200, the edge of the heating cup holder 220 far away from the heating cup body 230 is coated with a metal wrapping edge, and the metal wrapping edge improves the wear resistance of the heating cup 200 holder, so that the problem that the heating cup holder 220 is severely worn due to frequent contact with other objects can be avoided.

It should be apparent that, in another embodiment of the present invention, the cover 290 may be a suction cup-like structure made of elastic materials such as rubber and silica gel, and when the cover 290 covers the end of the heating cup 220 far from the heating cup 230, the cover 290 can elastically deform, so that a portion of the air inside the connector 280 is exhausted to form a negative pressure, and the cover 290 is adsorbed to the heating cup 220 by air pressure. If it is necessary to heat water using the heating cup 200, only one side of the cover 290 needs to be lifted so that the connector 280 communicates with the outside.

In addition, in other embodiments of the present invention, the cover 290 may be rotatably connected to the heating cup 200, that is, the end of the heating cup 220 away from the heating cup body 230 is convexly provided with a rotating shaft 223, and correspondingly, the cover 290 is provided with a shaft sleeve 291 matched with the rotating shaft 223, so that the cover 290 is rotatably connected to the heating cup 220. When the heating cup 200 is in the idle state, the end of the cover plate 290 away from the rotating shaft 223 may be forced to rotate the cover plate 290 around the rotating shaft 223 and cover the end of the heating cup holder 220 away from the heating cup body 230, and the connector 280 on the heating cup holder 220 is covered while the cover plate 290 covers the end of the heating cup 200 away from the heating cup body 230.

Further, in order to avoid that the heating cup 200 is impacted or jolted during carrying, the cover 290 opens the end of the heating cup seat 220 away from the heating cup body 230, the cover 290 is provided with an elastic buckle (not shown) arranged opposite to the shaft sleeve 291, the elastic buckle can be arranged in a V shape, a U shape or other shapes, and a free end of the elastic buckle is fixedly connected with the end surface of the cover 290 facing the heating cup seat 220, and the other end of the elastic buckle extends out of the cover 290 laterally; correspondingly, a buckling groove is arranged on one side of the heating cup seat 220 opposite to the rotating shaft 223. When the cover plate 290 covers the end portion of the heating cup holder 220 far away from the heating cup body 230, the elastic buckle is buckled with the buckling groove, so that two opposite sides of the cover plate 290 are fixedly connected with the heating cup holder 220, and the problem that the end portion of the cover plate 290 far away from the heating cup body 230 is opened when the heating cup 200 is impacted or in a jolt state is avoided.

In addition, when the cover plate 290 needs to be opened, the user can apply force to the elastic buckle so that the elastic buckle is deformed under the force of the elastic buckle, thus the elastic buckle can be released from the buckle groove, further the side, far away from the rotating shaft 223, of the cover plate 290 is separated from the heating cup seat 220, and when a turnover force is applied to the cover plate 290, the cover plate 290 can be rotated around the rotating shaft 223 to open the end, far away from the heating cup seat 220, of the heating cup body 230, so that the connector 280 is exposed.

In order to better cover the cover plate 290 and seal the end of the heating cup holder 220 that is remote from the heating cup body 230, the heating cup 200 is further provided with a sealing ring (not shown) that is disposed around the edge of the cover plate 290. When the cover plate 290 covers the heating cup holder 220, the sealing ring is limited between the hole wall of the mounting hole 222 and the cover plate 290, so that the sealing between the cover plate 290 and the heating cup holder 220 is ensured, and further, the problem that external dust or water enters the connector 280, so that the connector 280 rusts to cause poor conduction is avoided.

It should be noted that, when the net heat cup 100 is in a heating state, that is, when the heat cup 200 is used for heating water, the temperature of the water in the heat cup 200 will be higher and higher until boiling, and a large amount of bubbles will be generated by the boiling water, so that boiling water in the heat cup 200 will be turned over, and thus the boiling water in the heat cup 200 will be easy to splash out, and considering the safety problem of the user, in an embodiment of the present invention, the heat cup 200 is further provided with a cup cover 500, and the cup cover 500 is used for sealing the heat cup opening 240, so that the problem of splashing boiling water in the heat cup 200 is avoided.

However, after the cup mouth 240 of the heating cup is covered by the cup cover 500, water vapor inside the heating cup 200 cannot be discharged, and when water in the heating cup 200 is continuously heated to boiling, the water vapor inside the heating cup 200 is increased, so that the air pressure inside the heating cup 200 is increased, and once the air pressure inside the heating cup 200 exceeds the maximum bearing capacity of the heating cup 200, the heating cup 200 explodes. In order to ensure the safety of the user and avoid the explosion of the heating cup 200, the heating cup 200 is provided with a pressure relief device 510, referring to fig. 12, the pressure relief device 510 is automatically opened when the air pressure in the heating cup 200 reaches the warning air pressure, so that the high-pressure air in the heating cup 200 can be timely discharged, thereby avoiding the occurrence of the problem of the explosion of the heating cup 200 due to the overhigh air pressure in the heating cup, and further improving the safety performance of the heating cup 200.

Specifically, the cup cover 500 includes an inner cover 520, the inner cover 520 having an inner cover rim 521 fixedly connected to the heating cup mouth 240 and an inner cover body 522 closing the inner cover rim 521, the inner cover body 522 being provided with a first vent hole 5221 therethrough; the pressure relief device 510 is mounted on the inner cap body 522 and includes a sealing plug 511 and a first resilient return element 512 connected to the sealing plug 511.

The first elastic restoring element 512 has a first compression state and a second compression state, and when the first elastic restoring element 512 is in the first compression state, that is, when the force of the gas in the heating cup 200 acting on the sealing plug 511 is smaller than the elastic force of the first elastic restoring element 512, the sealing plug 511 seals the first vent 5221 under the elastic supporting of the first elastic restoring element 512; when the first elastic restoring member 512 is in the second compression state, that is, when the force of the gas in the heating cup 200 acting on the sealing plug 511 is greater than the elastic force of the first elastic restoring member 512, at this time, the sealing plug 511 is jacked by the high-pressure gas, and the first elastic restoring member 512 is correspondingly deformed along with the jacking process of the sealing plug 511, so that the first vent 5221 is in an open state, and the high-pressure gas in the heating cup 200 can be discharged through the first vent 5221, thereby avoiding the problem that the heating cup 200 explodes due to the overhigh gas pressure in the heating cup 200.

It should be noted that, the first elastic restoring member 512 may be a coil spring, a spring plate, or other elastic structures, and the elastic restoring member is not specifically limited herein.

In an embodiment of the present invention, the first elastic restoring member 512 is a coil spring, and the sealing plug 511 is adapted to the coil spring, and has a connecting rod 5111, a sealing portion 5112 disposed at one end of the connecting rod 5111, and a limiting portion 5113 disposed at the other end of the connecting rod 5111. When the pressure relief device 510 is fixedly mounted on the inner cap 522, the connecting rod 5111 passes through the first vent hole 5221 and is in clearance fit with the first vent hole 5221, the sealing portion 5112 is located on the outer side of the inner cap 522, the limiting portion 5113 is located on the inner side of the inner cap 522, the spiral spring is sleeved on the connecting rod 5111, one end of the spiral spring is abutted with the limiting portion 5113, and the other end of the spiral spring is abutted with the inner cap 522.

It should be noted that, the length of the connecting rod 5111 is smaller than the length of the coil spring, that is, when the heating cup 200 is in the idle state, the coil spring is in the first compressed state, so that the sealing portion 5112 located outside the inner cover 522 seals the first air hole 5221 on the inner cover 522 when the elasticity of the coil spring abuts against the lower limit portion 5113. When the force of the high-pressure gas in the heating cup 200 acting on the limit part 5113 is smaller than the elastic force of the spiral spring, the spiral spring cannot deform, so that the sealing part 5112 of the first vent 5221 is still used for sealing the first vent 5221, further, the loss of heat in the heating cup 200 can be reduced, and the heating speed of the heating cup 200 can be improved; when the force of the high pressure gas in the heating cup 200 acting on the limit portion 5113 is greater than the elastic force of the coil spring, that is, the limit portion 5113 moves in the direction approaching the inner cover 522 under the action of the high pressure gas, the coil spring is compressed to the second compressed state, the connecting rod 5111 extends out of the first vent hole 5221 while the limit portion 5113 moves, so that the sealing portion 5112 sealing the first vent hole 5221 is separated from the inner cover 522, the first vent hole 5221 is in an open state, and the high pressure gas in the heating cup 200 can be discharged to the outside through the first vent hole 5221, thereby avoiding the problem that the explosion of the heating cup 200 occurs due to the over high pressure in the heating cup 200.

In another embodiment of the present invention, the first elastic restoring element 512 is a spring, one end of the first elastic restoring element is fixedly installed on the outer surface of the inner cap 522, the other end of the first elastic restoring element is provided to cover the first vent 5221, the sealing plug 511 is installed on the surface of the spring facing the inner cap 522 in a sheet shape, and the first vent 5221 is blocked under the elastic supporting action of the spring.

When the force of the high-pressure gas in the heating cup 200 acting on the limiting part 5113 is smaller than the elastic force of the elastic sheet, namely when the heating cup 200 is in an idle state or is heated initially, the elastic sheet is in a first compression state, and the sealing plug 511 is tightly attached to the inner cover 522 under the action force of the elastic sheet restoring deformation, so that the first vent hole 5221 is blocked, thus the heat loss in the heating cup 200 can be reduced, and the heating speed of the heating cup 200 is improved; when the force of the high-pressure gas in the heating cup 200 acting on the limit portion 5113 is greater than the elastic force of the elastic sheet, the elastic sheet deforms along with the jack-up of the sealing plug 511 in a direction away from the inner cover 522, and is in the second compression state, and because a gap is formed between the sealing plug 511 and the inner cover 522 at this time, the high-pressure gas in the heating cup 200 can be discharged through the first vent 5221, so that the problem that the heating cup 200 explodes due to the fact that the gas pressure in the heating cup 200 is too high is avoided.

Obviously, one end of the elastic piece may be fixedly connected with the hole wall of the first vent hole 5221 or the inner surface of the inner cover 522, and the other end of the elastic piece passes through the first vent hole 5221 and is fixedly connected with the sealing plug 511 for sealing the first vent hole 5221, so that the sealing plug 511 seals the first vent hole 5221 when the elastic piece is in the first compressed state; when the spring is in the second compressed state, the second ventilation hole 5321 is opened. For the specific working procedure of the elastic sheet and the sealing plug 511, reference may be made to the above embodiment, and the details are not repeated here.

Since the high temperature gas is discharged from the first vent hole 5221 and the high temperature gas easily scalds the user, in order to prevent the user from being scalded by the high temperature gas, in an embodiment of the present invention, the cap cover 500 is further provided with an outer cap 530 covering the inner cap 520, the outer cap 530 includes an outer cap rim 531 disposed in a ring shape, and an outer cap 532 covering one side of the outer cap rim 531, and the outer cap 532 is provided with a second vent hole 5321.

When the inner cap 520 is assembled with the outer cap 530, the outer cap rim 531 of the outer cap 530 is fitted over the outer side of the inner cap rim 521 and is fixedly connected to the inner cap rim 521, and the outer cap 532 of the outer cap 530 is disposed outside the inner cap 522 and spaced apart from the inner cap 522. By the arrangement, on one hand, the outer cover 532 of the outer cover 530 is ensured not to influence the normal operation of the pressure relief device 510; on the other hand, when the high-pressure gas in the heating cup 200 is discharged between the inner cover 522 and the outer cover 532 through the first vent hole 5221, the high-temperature gas discharged between the inner cover 522 and the outer cover 532 is cooled once and then discharged through the second vent hole 5321 in the outer cover 532, so that the problem that the user is scalded by the high-temperature gas is effectively avoided.

The inner flange 521 and the outer flange 531 may be connected and fixed by other connection methods such as screw connection, snap connection, and socket connection, and the connection method of the inner flange 521 and the outer flange 531 is not particularly limited herein.

In order to prevent the cup cover 500 from falling off the heating cup rim 240 due to the impact of high-pressure gas when the heating cup 200 heats hot water, in an embodiment of the present invention, the inner wall surface of the inner lid flange 521 is provided with an inner thread section, and correspondingly, the outer wall surface of the heating cup rim 240 is provided with an outer thread section. When the cup cover 500 covers the heating cup rim 240, the inner thread section of the inner cover rim 521 is in threaded connection with the outer thread section of the heating cup rim 240, so that the stability of connection between the cup cover 500 and the heating cup rim 240 is ensured, and the problem that the cup cover 500 is jacked up by high-pressure gas to fall off from the heating cup rim 240 is avoided.

It is obvious that the inner lid edge 521 may also be fastened to the heating cup rim 240 by a snap connection or other connection means, which is not particularly limited herein.

It should be noted that, after the heating cup 200 heats the water inside, if the user needs to use the hot water, the cup cover 500 needs to be opened, and since a large amount of water vapor remains inside the heating cup 200 when the heating cup 200 just stops heating, when the cup cover 500 is opened, the heating cup opening 240 emits a large amount of high temperature water vapor, and if the distance between the user and the heating cup opening 240 is too short, the user is easily scalded by the high temperature water vapor.

In view of the safety problem of the user, in an embodiment of the present invention, referring to fig. 13, the water outlet 5322 is provided on the cup cover 500, and a sliding cover 540 is slidably mounted on the outer surface of the cup cover 500, and the sliding cover 540 is used for blocking/opening the water outlet 5322 on the cup cover 500. Namely, when the user takes water, the user applies force to the sliding cover 540, so that the sliding cover 540 slides relative to the cup cover 500 and the water outlet 5322 is exposed, and hot water in the heating cup 200 can flow out through the water outlet 5322 on the cup cover 500; when the water taking is finished, the user can apply force to the sliding cover 540, so that the sliding cover 540 slides relative to the cup cover 500 and the water outlet 5322 is blocked, and thus the hot water in the heating cup 200 is prevented from flowing out through the water outlet on the cup cover 500. By the arrangement, the problem that a user is scalded by high-temperature steam when opening the cup cover 500 is avoided. In addition, the water in the heating cup 200 is poured out through the water outlet 5322 on the cup cover 500, so that the loss of hot water heat in the heating cup 200 can be reduced, and the heat preservation effect of the heating cup 200 can be improved.

In an embodiment of the present invention, referring to fig. 12 to 17, the cup cover 500 includes an outer cap 530, the outer cap 530 has an annular outer cap rim 531 and an outer cap 532 covering one side of the outer cap rim 531, the water outlet 5322 is disposed through the outer cap 532, and the outer cap 532 is disposed through a radially extending relief groove 5323 along the water outlet 5322; the surface of the sliding cover 540 facing the outer cover 532 is provided with a clasp 541.

When the sliding cover 540 is assembled with the outer cover 530, the hook 541 extends from the releasing slot 5323 to a side of the outer cover 532 opposite to the sliding cover 540, and is slidably connected to a slot edge of the releasing slot 5323, so that the entire sliding cover 540 is slidably mounted on the outer surface of the outer cover 532.

The number of the hooks 541 is plural, and the hooks 541 are distributed in two rows, and one of the hooks 541 in two rows is slidably connected to a slot edge on one side of the relief slot 5323, and the other hook 541 in two rows is slidably connected to a slot edge on the other opposite side of the relief slot 5323. The plurality of hooks 541 provide for balanced forces on the sliding cover 540, and thus, the sliding cover 540 can slide on the outer cover 532 more smoothly.

Further, the edge of the relief groove 5323 is convexly provided with a guide rod 5324 extending along the extending direction of the relief groove 5323, and the surface of each guide rod 5324 facing away from the outer cover 532 is spherical, and the hook portion of each clasp 541 is adapted to the shape of each guide rod 5324. By this arrangement, the problem that the sliding cover 540 does not slide smoothly due to the engagement of the hook portion of the clasp 541 with the guide lever 5324 is avoided.

Of course, a plurality of relief grooves 5323 may be provided in parallel in the outer cover 532; the surface of the sliding cover 540 facing the outer cover 532 is correspondingly provided with a plurality of hooks 541, and each hook 541 correspondingly passes through a relief slot 5323 and is fastened to a slot edge of the relief slot 5323. This also equalizes the force applied to the sliding cover 540 and thus allows the sliding cover 540 to slide more smoothly over the outer cover 532.

In order to facilitate the resetting of the sliding cover 540, the heating cup 200 is further provided with a second elastic resetting piece 550, one end of the second elastic resetting piece 550 is connected with the sliding cover 540, and the other end of the second elastic resetting piece 550 is fixedly connected with the outer cover 532. When the sliding cover 540 opens the water outlet 5322 of the outer cover 532, the second elastic restoring member 550 is in a compressed state; when the water outlet 5322 on the outer cover 532 needs to be plugged, the sliding cover 540 slides towards the direction close to the water outlet 5322 under the action of the elastic deformation of the second elastic reset piece 550, so that the sliding cover 540 is convenient to reset.

It should be noted that, the second elastic restoring member 550 may be a coil spring, a spring plate, or other elastic structures, and preferably, the second elastic restoring member 550 is a coil spring. In order to facilitate the installation of the coil spring, in an embodiment of the present invention, the inner cover 521 is provided with a sliding groove 5325 disposed in parallel with the relief groove 5323; note that, if the length and width of the relief groove 5323 on the inner lid 521 are sufficiently large, the relief groove 5323 may also serve as the sliding groove 5325; the surface of the sliding cover 540 facing the inner cover 521 is convexly provided with a limiting block 542. When the slide cover 540 is slidably mounted on the inner cover 522, the stopper 542 extends into the sliding groove 5325 and slides along the extending direction of the sliding groove 5325, the coil spring is mounted in the sliding groove 5325, one end of the coil spring abuts against the stopper 542, and the other end of the coil spring abuts against the sliding groove 5325 in a direction away from the water outlet hole. This facilitates the fixed installation of the second elastic restoring member 550.

Further, the sliding groove 5325 is provided with a positioning rod 5326 protruding from the wall of the water outlet 5322, and the limiting block 542 is provided with a positioning groove 5421 with a downward opening. When the coil spring is mounted in the slide groove 5325, one end of the coil spring is coupled to the positioning rod 5326, and the other end of the coil spring extends into the positioning groove 5421. By the arrangement, on one hand, the coil spring is convenient to fixedly mount, and on the other hand, the coil spring is prevented from falling off from the limiting block 542 or the positioning rod 5326.

Further, the positioning rod 5326 may also extend in a direction approaching the stopper 542 and be disposed through the stopper 542. The positioning rod 5326 can limit the spiral spring, so that the spiral spring can only deform along the axial direction of the spiral spring when being extruded, and further, when the spiral spring is prevented from being compressed, the middle part of the spiral spring deforms towards other directions, so that the sliding cover 540 cannot slide in place, and the opening of the water outlet 5322 on the outer cover 532 is influenced.

Considering that the second elastic restoring member 550 is in a compressed state when the sliding cover 540 is opened, the user needs to press the sliding cover 540 all the time, so as to avoid restoring the sliding cover 540 under the action of restoring the elastic deformation of the second elastic restoring member 550, which brings inconvenience to the user. To facilitate the pouring of water by the user, in one embodiment of the present invention, the outer surface of the outer cover 532 is provided with a stop boss 5327, and the sliding cover 540 faces the surface of the outer cover 532 to mount the stop 560. When the sliding cover 540 opens the water outlet 5322, the stop member 560 cooperates with the stop boss 5327 to position the sliding cover 540, so that the sliding cover 540 is prevented from automatically resetting under the action of the second elastic resetting member 550, and the problem of blocking the water outlet is avoided, thereby facilitating the pouring of water by a user.

Specifically, the stopper 560 is formed by continuously bending a metal elastic sheet, and has a first bending section 561 fixedly connected to the sliding cover 540, a second bending section 562 extending from the first bending section 561 towards a direction close to the outer cover 532, and a third bending section 563 bending from an end of the second bending section 562 away from the first bending section 561 towards a direction away from the outer cover 532, wherein a surface of the stopper boss 5327 facing the water outlet 5322 is inclined towards a direction away from the water outlet, a surface of the stopper boss 5327 facing away from the water outlet 5322 is inclined towards a direction close to the water outlet, and an included angle between the surface of the stopper boss 5327 facing the water outlet 5322 and the outer cover 532 is smaller than an included angle between the surface of the stopper boss 5327 facing away from the water outlet 5322 and the outer cover 532.

When the sliding cover 540 opens the water outlet, the connection part of the second bending section 562 and the third bending section 563 slides along the surface of the stop boss 5327 facing the water outlet 5322, and when the connection part of the third bending section 563 and the second bending section 562 passes over the highest part of the stop boss 5327, the second bending section 562 is abutted with the surface of the stop boss 5327 facing away from the water outlet 5322, and limits the sliding cover 540; when the sliding cover 540 covers the water outlet, the user slides the sliding cover 540 to deform the second bending section 562, so that the connection between the second bending section 562 and the third bending section 563 can pass over the highest position of the stop boss 5327, and the connection between the second bending section 562 and the third bending section 563 passes over the highest position of the stop boss 5327, and the sliding cover 540 slides relative to the outer cover 532 under the action of elastic deformation recovery of the second elastic restoring piece 550 to seal the water outlet on the outer cover 532.

Because the outer cover 532 is provided with the water outlet 5322 and the relief groove 5323, in order to ensure the tightness of the entire cup cover 500, the cup cover 500 is further provided with the inner cover 520, the inner cover 520 includes an inner cover edge 521 abutting against the heating cup rim 240, and an inner cover body 522 sealing one side of the inner cover edge 521, and the inner cover body 522 is provided with the water outlet 5222 in a penetrating manner. In order to prevent the inner cap body 522 from affecting the sliding of the sliding cover 540, the outer cap body 532 of the outer cap 530 is spaced apart from the inner cap body 522 of the inner cap 520 when the outer cap 530 is assembled with the inner cap 520; in order to communicate the water passing hole 5222 of the inner cap body 522 with the water passing hole 5322 of the outer cap body 532, the inner surface of the outer cap body 532 is provided with a water flow passage 5328, and the other end of the water flow passage 5227 is spaced apart from the water passing hole 5222 in a direction in which the inner cap body 522 is close to or away from the outer cap body 532, preferably, the end of the water flow passage 5227 away from the water passing hole 5322 is disposed opposite to the water passing hole 5222.

The cup cover 500 further includes a water baffle 570 connected to the sliding cover 540, and the water baffle 570 penetrates through the water through hole 571, the water baffle 570 is slidably mounted between the inner cover 522 and the port of the water flow channel 5328, and the water baffle 570 is fixedly connected to the sliding cover 540 and slides along with the sliding cover 540.

When the user needs to take the hot water, only the sliding cover 540 needs to be forced, so that the sliding cover 540 slides relative to the outer cover 532 and the water outlet 5322 is exposed; meanwhile, the water baffle 570 slides along with the sliding cover 540 and slides between the inner cover 522 and the ports of the water flow channel 5328, when the sliding cover 540 slides to the position of opening the water outlet 5322, the water through hole 571 on the water baffle 570 communicates the water outlet on the inner cover 522 with the water flow channel 5328, and at this time, water in the heating cup 200 flows out through the water through hole 5222 on the inner cover 522, the water through hole 571 on the water baffle 570, the water flow channel 5328 on the outer cover 532 and the water outlet 5322 on the outer cover 532 in sequence, so as to be used by a user.

When the user finishes taking water, the user only needs to apply force to the sliding cover 540 to reset the sliding cover 540, the sliding cover 540 will block the water outlet 5322 on the outer cover 532, meanwhile, the water baffle 570 slides along with the sliding cover 540, and when the sliding cover 540 blocks the water outlet 5322, the water passing through hole 571 on the water baffle 570 is dislocated with the water passing hole 5222 on the inner cover 522 and the port of the water flow channel 5328, so that the water passing hole 5222 on the inner cover 522 and the port of the water flow channel 5328 are blocked by the water baffle 570. Since only the water passing hole 5222 and the first vent hole 5221 are provided on the inner cover 522, the sum of the areas of the water passing hole 5222 and the first vent hole 5221 is far smaller than the area of the relief groove 5323 on the inner cover 522, and the first vent hole 5221 is always in a blocking state when the heating cup 200 is not used, and the water passing hole 5222 is always in a blocking state when the sliding cover 540 is not opened, thus avoiding the problem that water in the heating cup 200 flows out from the water outlet 5322 when the sliding cover 540 does not open the water outlet 5322.

Further, in order to ensure tightness between the water flow channel 5328 and the water baffle 570, the water flow channel 5328 is flared to form a receiving groove 5328a adjacent to the port of the baffle 326, the cup cover 500 further includes a second sealing ring 580, the second sealing ring 580 is mounted in the receiving groove 5328a, and the second sealing ring 580 is further used for abutting against the water baffle 570. Since the second sealing ring 580 is respectively abutted against the groove wall of the accommodating groove 5328a and the water baffle 570, the tightness between the water flow channel 5328 and the water baffle 570 is ensured, and the gap between the water flow channel 5328 and the water baffle 570 caused by the uneven end of the water flow channel 5328 or the end of the water flow channel 5328 is avoided, so that the water in the heating cup 200 flows into the space between the inner cover 522 and the outer cover 532.

In order to facilitate the fixed connection between the water baffle 570 and the sliding cover 540, referring to fig. 17, the water baffle 570 is provided with a fixing hole 572 spaced from the water passing through hole 571, the surface of the sliding cover 540 facing the outer cover 532 is convexly provided with a fixing rod 543, and the fixing rod 543 extends between the inner cover 522 and the outer cover 532 and is inserted into the fixing hole 572, so that the connection between the sliding cover 540 and the water baffle 570 is realized. The plugging has the advantage of convenient and quick disassembly and assembly, and thus, the assembly of the water baffle 570 and the sliding cover 540 is convenient.

In order to make the sliding of the water guard 570 smoother, a ring-shaped limit rib (not shown) may be protruding on the surface of the inner cover 522 facing the outer cover 532, where the ring-shaped limit rib is used to limit the sliding of the water guard 570, so that the water guard 570 is prevented from deviating from the sliding track, and the water flow channel 5328 and the water hole on the inner cover 522 cannot be blocked or communicated by the water guard 570.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
