Referring to fig. 1, a switching valve 1000 according to an embodiment of the present invention may be applied to bathroom equipment such as a spray gun, tap, etc. The switching valve 1000 is used for controlling the water path of the bathroom equipment to be opened or closed so as to enable the bathroom equipment to be discharged or closed.

Referring to fig. 2 and 3, in the embodiment of the present invention, the switching valve 1000 includes a fixing member 100, a water sealing member 200, an actuating member 300, and a reset member 400, a water flow passage 110 is formed inside the fixing member 100, both ends of the fixing member 100 are respectively provided with a water inlet port 111 and a water outlet port 112 communicating with the water flow passage 110, and an inner wall of the water flow passage 110 is provided with a first stopper 120 and a second stopper 130 arranged along a circumferential direction of the fixing member 100. The water seal 200 includes a sealing portion 210 and a positioning portion 220, and when the positioning portion 220 is at a position where it cooperates with the first stopping portion 120, the sealing portion 210 closes the water inlet 111; when the positioning portion 220 is in a position to be engaged with the second stopper 130, the sealing portion 210 opens the water inlet port 111. The actuator 300 is configured to be movable in a first direction towards the closure 200 under the influence of an external force, which may be, for example, pulled or pressed by a user. The actuator 300 is further provided with a driving part 310, and the driving part 310 can enable the driving part 310 of the sealing member 200 to rotate along the circumferential direction of the fixing member 100, that is, the positioning part 220 is switched to a position matched with the first stopping part 120 or a position matched with the second stopping part 130 in a rotating manner. The reset element 400 is capable of applying a reset force to the seal 200 in a second direction that is opposite the first direction.

Referring to fig. 4, when the switching valve 1000 is applied to a bathroom apparatus, the bathroom apparatus includes a housing 500, a water inlet passage 511 and a water outlet passage 521 are formed in the housing 500, and a water outlet 530 is formed in the housing 500, which communicates with the water outlet passage 521. The switching valve 1000 is hermetically disposed in the water outlet channel 521 to block the water outlet channel 521, and the actuator 300 penetrates out of the housing 500. For example, when the bathroom equipment is required to be shut down, the user applies an external force F in the direction shown in fig. 4, pulls the actuating member 300 to move in the first direction, and drives the sealing member 200 to move to a corresponding position, such as a position where the positioning portion 220 and the second stopping portion 130 are separated, and the driving portion 310 can drive the sealing member 200 to rotate. After the external force is removed, for example, the hands are loosened, the reset element 400 drives the water sealing member 200 to move towards the second direction, so that the positioning portion 220 is matched with the first stopping portion 120, the sealing portion 210 seals the water inlet port 111, and water cannot enter the water outlet 530 through the water inlet port 111, so that the bathroom equipment is in a closed state and no water is discharged.

When the bathroom equipment needs to be used for water outlet, referring to fig. 5, the actuating member 300 is pulled once again by an external force, and after the actuating member 300 moves in the first direction and drives the water sealing member 200 to move to a corresponding position, for example, a position where the positioning portion 220 and the first stopping portion 120 are separated, the driving portion 310 drives the water sealing member 200 to rotate. After the external force is removed, the reset element 400 drives the water sealing member 200 to move towards the second direction, at this time, the positioning portion 220 is matched with the second stop portion 130, the sealing portion 210 opens the water inlet port 111, the bathroom equipment is in a normally open state, and water can sequentially pass through the water inlet channel 511, the water outlet channel 521, the water inlet port 111, the water flow channel 110 and the water outlet port 112, and finally water is discharged from the water outlet 530.

By adopting the scheme, the actuating piece 300 is controlled without applying external force for a long time by a user, the bathroom equipment can be ensured to normally open out water by pulling the actuating piece 300 once, the water outlet is closed after pulling the actuating piece 300 once again, the operation is simple, and the use experience of the user can be improved.

It should be noted that, in another embodiment of the present invention, the manner of pulling the actuating member 300 may be adopted, and the manner of pressing the actuating member 300 may also be adopted. For example, referring to fig. 6, in the embodiment of the present invention, the actuating member 300 further includes a button 340, the button 340 is exposed outside the housing 500, and the actuating member 300 can drive the water sealing member 200 to move along the first direction by applying the external force F to press the button 340, and after the water sealing member 200 moves to a proper position, the driving portion 310 drives the water sealing member 200 to rotate. After the hands are loosened, the reset element 400 drives the water seal 200 to move towards the second direction, at this time, the positioning part 220 is matched with the first stop part 120 or the second stop part 130, and the sealing part 210 opens or closes the water inlet 111, so that the bathroom equipment is in a normally open state or a closed state.

The reset element 400 may be a spring, and two ends of the spring are respectively in abutting fit with the housing 500 and the sealing member 200. Of course, the reset element 400 may also be a silicone member, a rubber member, a tension spring, an electromagnetic valve, a motor, etc., and may be capable of driving the water seal member 200 to move along the second direction.

Referring to fig. 7 and 8, in the embodiment of the present invention, the outer circumferential wall of the sealing part 210 is provided with a groove 211, and a first seal ring 212 is installed in the groove 211. When the positioning portion 220 is matched with the first stop portion 120, the sealing portion 210 is connected with the inner wall of the water inlet 111 by the first sealing ring 212 in a sealing manner, so as to improve the sealing performance, avoid water leakage, water seepage and the like, and improve the reliability of the switching valve 1000.

When the positioning portion 220 and the second stop portion 130 are engaged, the first seal ring 212 can be engaged with the plurality of clamping pieces 150, so as to further reduce the risk of loosening and falling off the first seal ring 212. And a plurality of grip tabs 150 are arranged at intervals, so that water can enter the water inlet port 111 through gaps between adjacent grip tabs 150, the influence of the grip tabs 150 on water inlet is reduced, and the structure design is reasonable and reliable.

With continued reference to fig. 10, in the embodiment of the present invention, the inner wall of the clip 150 is inclined to the radial outside of the fixing member 100 in a direction away from the water inlet port 111. Alternatively, the diameter of the circle formed by the inner walls of the plurality of grip pieces 150 is larger than the inner diameter of the water inlet port 111. When the sanitary equipment is switched from the closed state to the normally open state, since the grip piece 150 is inclined outwardly, the water passing area is gradually increased, not suddenly increased, when the water seal 200 opens the water inlet port 111. The water seal 200 gradually reduces the water passage area in the process of closing the water passage opening. Therefore, the impact caused by the instant of opening or closing the water inlet 111 can be reduced, the bathroom equipment can be conveniently opened or closed, and the use experience of a user is improved.

Referring to fig. 11 and 12, in the embodiment of the present invention, the actuating member 300 further includes a transmission rod 320 and an end 330, the end 330 is connected to one end of the transmission rod 320, the outer circumferential wall of the end 330 is provided with a first guide member, the inner wall of the water flow channel 110 is provided with a second guide member, and the second guide member is in guiding engagement with the first guide member, so as to guide the actuating member 300 to move along a preset direction, and reduce the occurrence of dislocation, deflection, etc. of the actuating member 300. The transmission rod 320 is inserted into the water sealing member 200 and is slidably and hermetically connected with the water sealing member 200 through a second sealing ring, so as to avoid water leakage, water seepage, and the like.

Further, in the embodiment of the present invention, as shown in fig. 11 and 12, the first guide member includes a plurality of bosses 331, the plurality of bosses 331 are uniformly distributed along the circumference of the end 330, and the second guide member is provided with a plurality of sliding grooves 140, and the plurality of sliding grooves 140 extend along the axis of the fixing member 100. The bosses 331 are connected to the sliding grooves 140 in a one-to-one correspondence manner, so as to guide the actuator 300 to slide along the extending direction of the sliding grooves 140. The sliding groove 140 and the boss 331 are in sliding fit, so that the structure is simple and reliable, the assembly is convenient, and the installation efficiency is improved. It should be noted that, in another embodiment, the first guide member may be provided with the sliding groove 140, and the second guide member may include a boss 331 extending along the axis of the fixing member 100, where the boss 331 is slidably engaged with the sliding groove 140. And selecting a proper scheme according to actual conditions.

Referring to fig. 1, in the embodiment of the present invention, a first water outlet 332 is formed between the outer circumferential wall of the end 330 and the inner wall of the water flow channel 110, and the water flow channel 110 communicates with the water outlet 112 through the first water outlet 332. When the sealing part 210 opens the water inlet port 111, water can be discharged from the first water outlet 332, and water discharge efficiency is high. In another embodiment, the second water outlet 333 may be directly disposed at the end 330, and the water flow channel 110 communicates with the water outlet 112 through the second water outlet 333. It should be noted that the first water inlet and the second water inlet may be set at the same time, so as to further improve the water outlet efficiency.

Referring to fig. 3, in the embodiment of the present invention, the inner wall of the water flow channel 110 is provided with a plurality of first guide tables 160, the plurality of first guide tables 160 are spaced apart along the circumferential direction of the fixing member 100, and the gaps between adjacent first guide tables 160 form first stop portions 120, that is, the first stop portions 120 are in a groove shape. The first guide table 160 includes a first protrusion 161 and a second protrusion 163 connected to each other, and a first inclined surface 162 and a second inclined surface 164 are provided on a side of the first protrusion 161 and the second protrusion 163 facing the water inlet port 111, respectively, and the inclination directions of the first inclined surface 162 and the second inclined surface 164 are the same. A second stopper 130 is formed at the junction of the first protrusion 161 and the second protrusion 163.

Referring to fig. 7, the positioning portion 220 includes a plurality of second guiding tables 221 disposed at intervals, and a third inclined surface 222 is disposed at an end of the second guiding tables 221 facing the water outlet 112. The third inclined surface 222 can be slidably engaged with the first inclined surface 162 or the second inclined surface 164 under the restoring force of the restoring element 400, so that the second guide table 221 is rotated to a position engaged with the first stopper 120 or a position engaged with the second stopper 130.

With the above scheme, when the bathroom equipment is required to be in a closed state, for example, as shown in fig. 8, the actuating member 300 drives the water sealing member 200 to move along the first direction by an external force, and after the water sealing member 200 moves to a corresponding position, the driving portion 310 drives the water sealing member 200 to rotate. After the hands are loosened, under the action of the restoring force of the restoring element 400, the water sealing member 200 moves along the second direction, and the third inclined surface 222 and the first inclined surface 162 are in sliding fit, so that the second guide table 221 is inserted into the first stop portion 120, and therefore the first stop portion 120 plays a role in avoiding and limiting the second guide table 221 to continue rotating, and the sealing portion 210 can be in sealing fit with the water inlet port 111 under the action of the restoring force. When the bathroom equipment is required to be in a normally open state, for example, as shown in fig. 9, the actuating member 300 drives the water sealing member 200 to move along the first direction by external force, and after the water sealing member 200 moves to a corresponding position, the driving portion 310 drives the water sealing member 200 to rotate. After the hands are loosened, under the action of the reset force of the reset element 400, the water sealing member 200 moves along the second direction, and the third inclined surface 222 and the second inclined surface 164 are in sliding fit, so that the second guide table 221 and the second stop part 130 are abutted, and the sealing part 210 can be kept in a state of opening the water inlet 111, thereby ensuring that the bathroom equipment can normally open water. Therefore, when the bathroom equipment is switched to be out of water or shut off, the operation is simple, and the user experience is good.

Referring to fig. 7, in the embodiment of the present invention, the water sealing member 200 is provided with an overflow plate 230 on a side facing the water outlet 112, and the periphery wall of the overflow plate 230 is provided with overflow grooves 231, for example, the overflow grooves 231 are provided with a plurality of overflow plates 230 at intervals along the periphery direction. Referring to fig. 10, the fixing member 100 includes a fitting wall 170, and the fitting wall 170 is formed with a water inlet port 111. When the bathroom equipment is required to discharge water, the water sealing member 200 gradually moves from a position abutting against the matching wall 170 to a position separated from the matching wall 170, for example, when the water sealing member 200 gradually moves under the driving of the actuating member 300. The water mainly enters the water flow channel 110 through the flow trough 231, and the water flow area is smaller at the moment; when the water seal is at a position separated from the fitting wall 170, water mainly enters the water flow passage 110 through the gap between the sealing portion 210 and the fixing member 100, and the water passage area is large, i.e., the water passage area is changed from small to large. The same principle is needed when the bathroom equipment is closed, and the water passing area is changed from large to small.

Therefore, by providing the flow-through groove 231, the water passage area of the water sealing member 200 can be changed from small to large or from large to small when moving, and the impact phenomenon caused by the abrupt change of the water passage area can be effectively improved. Meanwhile, after the launder 231 is arranged, when the water inlet port 111 is used for water inflow, the water flow direction is changed from the direction perpendicular to the wall surface of the fixing piece 100 into inclined water inflow, so that the water pressure loss is reduced, and the water outflow smoothness is improved.

Referring to fig. 10 and 11, in the embodiment of the present invention, the driving part 310 is provided at the end 330 facing the end surface of the sealing member 200, and the driving part 310 includes a fourth inclined surface 311, and the fourth inclined surface 311 can be slidably engaged with the third inclined surface 222 so as to rotate the second guide table 221. For example, when the actuator 300 is driven to move in the first direction by an external force, the fourth inclined surface 311 and the third inclined surface 222 abut.
