Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In one embodiment, as shown in fig. 1-5, a water purifier 10 is provided, comprising a filter element assembly 11 and a handle 12, wherein the handle 12 is rotatably connected with the filter element assembly 11. The position of rotating and connecting the handle 12 with the filter element assembly 11 is an adapter point, and the position of rotating and connecting the handle 12 on the filter element assembly 11 is a supporting point.

Further, as shown in fig. 6, the filter element assembly 11 is provided with a joint 112. The water purifier 10 further includes a water channel plate 132, as shown in fig. 8 and 9, an interface 1324 matched with the joint 112 is provided on the water channel plate 132. As shown in fig. 1 to 5, the connector 112 of the filter element assembly 11 can be inserted into the connector 1324, so that the raw water can enter the filter element assembly 11, and the filtered pure water can be discharged out of the filter element assembly 11.

Furthermore, a limiting portion 1321 is arranged on the water path plate 132, and the handle 12 is provided with a locking portion 1221 and a detaching portion 1222. As shown in fig. 1 and 3, when the handle 12 rotates forward relative to the filter element assembly 11, the locking portion 1221 presses against the limiting portion 1321 so that the joint 112 is inserted into and pressed against the interface 1324. Specifically, the forward rotation described herein may refer to a state in which the handle 12 rotates counterclockwise at an angle shown in fig. 1 and 3, such as a state in which the locking portion 1221 is just in contact with the limiting portion 1321 shown in fig. 1, and a state in which the locking portion 1221 is completely pressed against the lower side of the limiting portion 1321 when the joint 112 is completely pressed in the interface 1324 shown in fig. 3.

As shown in fig. 4 and 5, when the handle 12 is turned reversely relative to the filter element assembly 11, the detaching portion 1222 presses against the stopper 1321 to pull the connector 112 out of the interface 1324. Specifically, the reverse rotation may refer to the handle 12 being rotated clockwise at the angle shown in fig. 4 and 5, the state when the detachable portion 1222 of the handle 12 is initially contacted with the limiting portion 1321 when the handle 12 is reversed is shown in fig. 4, and the state when the handle 12 is rotated to release the joint 112 from the interface 1324 is shown in fig. 5.

Above-mentioned scheme provides a purifier 10, based on spacing portion 1321 directly sets up on the water route board 132, handle 12 directly sets up on the filter element group spare 11, thereby utilizes handle 12 with cooperation relation between the spacing portion 1321 can make joint 112 with the direct counterpoint locking of interface 1324, perhaps directly break away from, the intermediate dimension chain of minimizing reduces the possibility of middle assembly error, thereby reduces the requirement that reduces each parts machining, reduces the processing degree of difficulty. Specifically, in the assembling process, the joint 112 on the filter element assembly 11 is first opposite to the interface 1324 on the water route board 132, and then the handle 12 is rotated forward, so that the locking portion 1221 is pressed against the limiting portion 1321 until the joint 112 is inserted into and pressed against the interface 1324. The connector 112 of the filter element assembly 11 is always in communication with the connector 1324 of the water passage plate 132 without any other external force. When the joint 112 and the interface 1324 need to be disassembled, the handle 12 is reversed, so that the disassembling portion 1222 is pressed against the limiting portion 1321 to pull the joint 112 out of the interface 1324.

Also, the strength of the waterway plate 132 is generally made high in order to allow the waterway plate 132 to withstand a high water pressure. And then the limiting part 1321 is arranged on the water channel plate 132, so that the overall strength in the dismounting process can be effectively guaranteed, and the stress condition of the whole machine is improved.

Further, in order to ensure the sealing reliability when the adaptor 112 is connected to the port 1324, in one embodiment, as shown in fig. 6, the adaptor 112 is provided with a sealing ring, and when the adaptor 112 is inserted into the port 1324, the sealing ring is compressed between the adaptor 112 and the sidewall of the port 1324.

The sealing ring prevents relative movement between the connector 112 and the port 1324, so that a large force is required for assembly and disassembly.

Further to this, in one embodiment, as shown in fig. 7, the handle 12 is provided with a holding portion 1211, and the holding portion 1211, the transfer point and the locking portion 1221 on the handle 12 constitute a first labor-saving lever. Specifically, the surface of the locking portion 1221 that abuts against the limiting portion 1321 is located on a side of the adapter point away from the holding portion 1211. In the assembling process, as shown in fig. 1 and fig. 3, after a downward acting force is applied to the holding portion 1211, by means of the first labor-saving lever, the limiting portion 1321 provides a support for the locking portion 1221, the handle 12 rotates with a point on the locking portion 1221, which abuts against the limiting portion 1321, as a fulcrum, the switching point moves relative to the water channel plate 132, and the filter element assembly 11 connected to the handle 12 is synchronously driven to move relative to the water channel plate 132, so that the joint 112 is inserted into the interface 1324. The force required to act on the grip 1211 is effectively reduced by using the lever labor saving principle, so that the operation process is more convenient.

Alternatively, the surface of the locking portion 1221 that abuts against the limiting portion 1321 may be located between the holding portion 1211 and the transfer point, as long as the holding portion 1211, the transfer point, and the locking portion 1221 on the handle 12 form a first labor-saving lever. For example, the turning point is located at one end of the handle 12, when the joint 112 is initially aligned with the interface 1324, the handle 12 can be adjusted to the position where the locking portion 1221 is located at the side of the limiting portion 1321 away from the joint 112, and then a force in the direction close to the joint 112 is applied to the holding portion 1211, as the handle 12 rotates, the limiting portion 1321 provides a pressing force to the locking portion 1221, so that the turning point moves relative to the water route board 132, and synchronously drives the filter element assembly 11 connected with the handle 12 to move relative to the water route board 132, so that the joint 112 is inserted into the interface 1324.

Further, as shown in fig. 7, the holding portion 1211, the adapting point and the detaching portion 1222 of the handle 12 form a second labor-saving lever. Specifically, the surface of the detaching portion 1222 abutting against the limiting portion 1321 is located on a side of the adapting point away from the holding portion 1211. Fig. 3 shows a state where the connector 112 is mounted in the interface 1324, and at this time, the limiting portion 1321 abuts against the locking portion 1221. When the disassembly is required, as shown in fig. 4 and 5, the upward lifting force is applied to the grip 1211 of the handle 12, and the disassembly portion 1222 is gradually pressed against the limiting portion 1321 by the second labor-saving lever. In the process of reversing the handle 12, the limiting portion 1321 provides support for the detaching portion 1222, so that the handle 12 rotates with a point on the detaching portion 1222, which abuts against the limiting portion 1321, as a fulcrum, the transfer point moves relative to the water channel plate 132, and synchronously drives the filter element assembly 11 to move relative to the water channel plate 132, so that the joint 112 is pulled out from the interface 1324.

Similarly, optionally, a surface of the detaching portion 1222 abutting against the stopper portion 1321 may also be located between the adapting point and the holding portion 1211. Similar to the above-mentioned solution, the surface of the detaching portion 1222 abutting against the limiting portion 1321 may also be located between the holding portion 1211 and the adaptor point. When the adapter 112 is installed in the interface 1324, the stopper 1321 and the detaching element 1222 are sequentially arranged in the orientation of the interface 1324, and at this time, the holding element 1211 is provided with a downward pressure opposite to the orientation of the interface 1324, the detaching element 1222 is pressed against the stopper 1321, the adapter point moves upwards along the orientation of the interface 1324, and then the filter element assembly 11 moves along the orientation of the interface 1324 relative to the water channel plate 132, so that the adapter 112 is pulled out of the interface 1324.

Further, as shown in fig. 6, in an embodiment, one end of the filter element assembly 11 on which the joint 112 is provided is a head end, the supporting point is located at the head end of the filter element assembly 11, the joint 112 is suspended outside the head end of the filter element assembly 11, and an outlet of the joint 112 faces the tail end of the filter element assembly 11 along the axial direction of the filter element assembly 11. As shown in fig. 8 and 9, the interface 1324 is located on the top surface of the water channel plate 132, and the limiting portion 1321 is located on the top of the water channel plate 132. The direction of inserting and pulling the joint 112 is the axial direction of the filter element assembly 11.

As shown in fig. 1 and fig. 3, during the assembling process, the locking portion 1221 gradually presses against the side of the limiting portion 1321 close to the end of the filter element assembly 11, so that the connector 112 is tightly inserted into the interface 1324. As shown in fig. 4 and fig. 5, during the disassembling process, the disassembling portion 1222 is pressed against the side of the limiting portion 1321 away from the end of the filter element assembly 11.

More specifically, as shown in fig. 8 and 9, in one embodiment, two auxiliary plates 1325 are provided on the water path plate 132. The front surface of the water channel plate 132 faces the filter element assembly 11, the auxiliary plates 1325 extend to the front surface of the water channel plate 132, the two auxiliary plates 1325 are respectively positioned at the left side and the right side of the water channel plate 132, and the limiting part 1321 comprises a protrusion positioned on the side surface of the auxiliary plate 1325 which faces away from the filter element assembly 11.

The detaching part 1222 and the locking part 1221 are mainly located on the side of the auxiliary plate 1325 facing away from the filter element assembly 11 during the detaching process. In the process of rotating the handle 12, the positions of the detaching portion 1222, the locking portion 1221 and the limiting portion 1321 are changed, so that the detachment is realized.

Further, as shown in fig. 3, in an embodiment, a surface of the limiting portion 1321, which is pressed against the locking portion 1221, is a first mating surface 1322, and the first mating surface 1322 gradually extends toward a direction approaching the top surface of the waterway plate 132 in a direction approaching the waterway plate 132.

When the locking portion 1221 is pressed against the first mating surface 1322 to lock the filter element assembly 11, as shown in fig. 3, the acting force provided by the first mating surface 1322 to the locking portion 1221 can be decomposed into a first component force F1 along the axial direction of the filter element assembly 11 and a second component force F2 perpendicular to the water channel plate 132, in other words, the limiting portion 1321 provides not only the first component force F1 for the handle 12 and the filter element assembly 11 to insert the connector 112 in the interface 1324, but also provides the second component force F2 for the handle 12 and the filter element assembly 11 to abut against the water channel plate 132, so as to ensure that the handle 12 and the limiting portion 1321 are locked reliably.

Further, as shown in fig. 8 and 9, in one embodiment, a surface of the limiting portion 1321, which is pressed against the detaching portion 1222, is a second mating surface 1323. As shown in fig. 3, when the connector 112 is inserted into and pressed against the interface 1324, the detaching portion 1222 is spaced apart from the second mating surface 1323. In other words, the detachment portion 1222 and the second engagement surface 1323 are not in contact at the initial stage of the inversion of the handle 12, and a virtual position exists between the detachment portion 1222 and the second engagement surface 1323, so that the limiting portion 1321 does not obstruct the inversion of the handle 12. When the handle 12 is rotated by a predetermined angle, as shown in fig. 4, the detaching portion 1222 contacts the second mating surface 1323, and then the adapting point starts to move relative to the water board 132, so as to improve the operation feeling.

Specifically, in order to further improve the operation feel and avoid the occurrence of a sudden and sudden increase in resistance, as shown in fig. 3 to 5, the surface of the detaching portion 1222 abutting against the second mating surface 1323 is an arc-shaped convex surface. So that the length of the resistance arm of the second labor-saving lever is gradually increased in the process of reversely rotating the handle 12. When the detaching portion 1222 starts to press against the second mating surface 1323, the connector 112 and the interface 1324 start to move relatively, the required acting force is large, and the ratio of the power arm to the resistance arm is large, so that the labor saving ratio is large. As the handle 12 continues to reverse, the tightness of the pinch between the connector 112 and the interface 1324 decreases, the force required decreases, and the ratio of power arm to resistance arm decreases, decreasing the labor saving ratio. Therefore, the force change required by the user to act on the handle 12 in the whole process is small, and the operation hand feeling is improved.

Further, in an embodiment, as shown in fig. 1, the water purifier 10 further includes a support housing 131, the support housing 131 defines an installation cavity, and the filter element assembly 11 is inserted in the installation cavity. The orientation of the mounting cavity coincides with the orientation of the interface 1324. The water channel plate 132 is connected with the supporting shell 131 to form the whole casing assembly 13.

Specifically, in the assembling process, as shown in fig. 1, the filter element assembly 11 is initially inserted into the mounting cavity, the joint 112 is aligned with the interface 1324, then the handle 12 is rotated forward, the locking portion 1221 abuts against the limiting portion 1321, the transfer point on the handle 12 moves relative to the water channel plate 132, and the water channel plate 132 is connected with the support shell 131, so that the transfer point moves relative to the support shell 131 at the same time, and the filter element assembly 11 is mounted and locked in the mounting cavity while the joint 112 is locked in the interface 1324.

Similarly, in the process of reversing the handle 12, the joint 112 is pulled out of the interface 1324, and meanwhile, the filter element assembly 11 is pulled out from the installation cavity for a certain distance, so that the filter element assembly 11 is loosened relative to the water board 132 and the support shell 131.

Further, as shown in fig. 3 to 5, a limiting rib is disposed on the outer peripheral surface of the supporting shell 131, and the limiting rib is limited on one side of the auxiliary plate 1325 close to the bottom wall of the mounting cavity. So that when the dismounting portion 1222 is pressed against the limiting portion 1321 on the surface facing away from the bottom wall of the mounting cavity, the limiting portion 1321 and the auxiliary plate 1325 do not move toward the bottom wall of the mounting cavity, thereby providing a reaction force to the dismounting portion 1222 to dismount the filter element assembly 11 from the mounting cavity, and simultaneously releasing the connector 112 from the interface 1324.

Further, in one embodiment, as shown in fig. 7, the handle 12 includes a middle grip section 121 and connecting sections 122 at both ends of the middle grip section 121. The holding portion 1211 is located on the middle holding section 121, two connecting sections 122 are clamped on two sides of the filter element assembly 11, the two connecting sections 122 are provided with the transition points, and the two connecting sections 122 each include the locking portion 1221 and the detaching portion 1222. In other words, the handle 12 includes two first labor-saving levers and two second labor-saving levers. The holding portion 1211 forms a first labor-saving lever together with the transfer point and the locking portion 1221 on the same connecting section 122, and the holding portion 1211 forms a second labor-saving lever together with the transfer point and the detaching portion 1222 on the same connecting section 122. Be equipped with two on the water route board 132 spacing portion 1321, two spacing portions 1321 are located respectively the left and right sides of filter element subassembly 11 just respectively with two the linkage segment 122 corresponds.

The handle 12 is rotatably connected with the supporting point on the filter element assembly 11 through the transfer points on the connecting sections 122 at the two ends, the locking parts 1221 at the two ends of the handle 12 are synchronously contacted with the two limiting parts 1321 in the assembling process, and the disassembling parts 1222 at the two ends of the handle 12 are synchronously contacted with the two limiting parts 1321 in the disassembling process.

Further, in an embodiment, the limiting portion 1321 includes a limiting protrusion, as shown in fig. 7, a yielding groove 123 is provided between the locking portion 1221 and the detaching portion 1222, as shown in fig. 1 and fig. 3, when the handle 12 rotates forward, the limiting portion 1321 gradually enters the yielding groove 123 from an opening of the yielding groove 123 until the locking portion 1221 abuts against the limiting portion 1321 so as to insert and press the joint 112 into the interface 1324. In this case, the locking portion 1221 and the stopper portion 1321 are provided in this order in the direction of the interface 1324. When the handle 12 is turned reversely, as shown in fig. 4 and 5, the limiting portion 1321 gradually exits from the yielding groove 123 from the opening of the yielding groove 123, and the detaching portion 1222 gradually presses against the limiting portion 1321 until the joint 112 is pulled out from the interface 1324.

Specifically, as shown in fig. 7, the openings of the receding groove 123 are located at the end surfaces of the two ends of the handle 12, and the receding groove 123 penetrates through the inner side surface and the outer side surface of the handle 12, so that the locking portion 1221 and the detaching portion 1222 are arranged at an interval. As shown in fig. 3, when the stopper 1321 is located in the receding groove 123, the detaching part 1222 and the locking part 1221 are located at upper and lower sides of the stopper 1321, respectively. Here, the upper side of the limiting portion 1321 refers to a side away from the bottom wall of the mounting cavity, and the lower side refers to a side close to the bottom wall of the mounting cavity.

Specifically, as shown in fig. 3, the directions of the second component of force F2 are distributed approximately along the opening direction of the receding groove 123, so that the locking portion 1221 can block the limiting portion 1321 from exiting the receding groove 123.

Further, in one embodiment, as shown in fig. 7, the connecting section 122 is a plate-like structure. The connecting section 122 further includes a body portion 1223 connecting the locking portion 1221 and the detaching portion 1222. The main body portion 1223, the locking portion 1221 and the detaching portion 1222 enclose the relief groove 123.

As shown in fig. 1 to 5, two connecting sections 122 of a plate-shaped structure are located at two sides of the filter element assembly 11, and are respectively rotatably connected with the filter element assembly 11. The adapter point is located on the detachment portion 1222 based on the location on the body portion 1223 where the intermediate grip segment 121 is connected, relative to the locking portion 1221, closer to the detachment portion 1222. Therefore, as shown in fig. 1 and 3, the latching portion 1221 is disposed offset from the middle grip section 121, and a cantilever formed by connecting the latching portion 1221 and the body portion 1223 is suspended outside the middle grip section 121. In the locking process, when the locking portion 1221 abuts against the limiting portion 1321, the stress at the connection between the locking portion 1221 and the main body portion 1223 is large, and the fracture is likely to occur. Based on this, as shown in fig. 7, a reinforcing rib 125 is provided at a connection portion between the main body portion 1223 and the locking portion 1221, so that the strength of the cantilever is improved.
