[0043] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0044] In the first aspect, referring to Figures 1 to 3 The embodiments of the present application provide a distribution valve 100, which comprises a housing 1, a valve core assembly 2 and a driving assembly 3. The valve core assembly 2 is arranged in the housing 1, and the driving assembly 3 is arranged in the housing 1. The driving assembly 3 is used to drive the valve core assembly 2 to rotate in the housing 1, so as to change the water path of the water flow and change the on-off of the water path.

[0045] It should be noted that in the embodiments of the present application, the fluid flowing into the distribution valve 100 is taken as water, and in some other embodiments, the fluid can also be oil, water-oil mixture, cleaning agent, cleaning agent-water mixture and the like, which are not limited here.

[0046] For the above-mentioned housing 1, referring to Figure 2 and Figure 3 In some embodiments, the housing 1 comprises a first shell 11 and a second shell 12. The first shell 11 is in the shape of a cylinder, and the second shell 12 and the driving assembly 3 are arranged at two ends of the first shell 11, respectively.

[0047] In some embodiments, the second shell 12 and the drive assembly 3 can be detachably connected with the first shell 11, facilitating disassembly of the dispensing valve 100. Exemplarily, please refer to Figure 2 , the first shell 11 is provided with a first hole 111 and a second hole 112, the drive assembly 3 is provided with a third hole 31, and the second shell 12 is provided with a fourth hole 121; the dispensing valve 100 further comprises fasteners 4, some of which pass through the third hole 31 and are inserted into the first hole 111, and the others of which pass through the fourth hole 121 and are inserted into the second hole 112, so as to detachably connect the second shell 12 and the drive assembly 3 with the first shell 11. Optionally, the first hole 111 and the second hole 112 are threaded holes, the third hole 31 and the fourth hole 121 are through holes, and the fasteners 4 are screws.

[0048] In some embodiments, please refer to Figures 2 to 4 , the housing 1 is provided with a water passage cavity 113, a water inlet 114, a first water outlet 122 and a first self-cleaning port 123, and the water inlet 114 communicates with the water passage cavity 113; the housing 1 comprises a sealing surface 124, the sealing surface 124 partially defines the water passage cavity 113, and the housing 1 is provided with a first water outlet hole 1241 and a first self-cleaning hole 1242 at the sealing surface 124, the first water outlet hole 1241 communicates with the first water outlet 122, and the first self-cleaning hole 1242 communicates with the first self-cleaning port 123. Specifically, the first shell 11 and the second shell 12 surround to form the water passage cavity 113; the water inlet 114 is arranged on the first shell 11 and penetrates to the inner wall of the first shell 11, so that the water inlet 114 communicates with the water passage cavity 113; one side of the second shell 12 has the sealing surface 124, and the other side of the second shell 12 has the first water outlet 122 and the first self-cleaning port 123, the first water outlet hole 1241 and the first self-cleaning hole 1242 extend from the sealing surface 124 to the other side of the second shell 12 and respectively communicate with the first water outlet 122 and the first self-cleaning port 123, so that the first water outlet 122 and the first self-cleaning port 123 communicate with the water passage cavity 113.

[0049] In some embodiments, the dispensing valve 100 comprises a first sealing ring 5 clamped between the first shell 11 and the second shell 12 to enhance the sealing performance of the water passage cavity 113. Optionally, the first sealing ring 5 is a rubber ring.

[0050] In some embodiments, please refer to Figure 1 and Figure 2The direction of the water flow in the water passage cavity 113 changes when the water flow passes through the first water outlet hole 1241 and flows into and out of the first water outlet 122, which is beneficial to buffering the water flow, making the flow rate of the water flow finally flowing out of the first water outlet 122 more stable, and reducing the water flow rate, so that the water flow sprayed by the water spraying assembly to the user is more stable and has a more moderate flow rate, which is beneficial to improving the user experience.

[0051] The water spraying assembly is a device for spraying water flow, and the water flow can form water splashes and then be sprayed to the user to clean the user. Optionally, the water spraying assembly is a nozzle, a shower head or the like.

[0052] In some embodiments, referring to Figure 1 and Figure 2 The direction of the first self-cleaning port 123 is the same as the direction of the first self-cleaning hole 1242. The direction of the water flow in the water passage cavity 113 does not change when the water flow passes through the first self-cleaning hole 1242 and flows into and out of the first self-cleaning port 123, which is beneficial to reducing the momentum loss of the water flow and enhancing the washing effect of the water flow on the water spraying assembly.

[0053] For the above-mentioned valve core assembly 2, referring to Figure 2 and Figure 3 The valve core assembly 2 is arranged in the water passage cavity 113, and the valve core assembly 2 includes a valve plate 21 abutting against the sealing surface 124 on one side in the thickness direction, and the valve plate 21 is used for sealing the first water outlet hole 1241 and the first self-cleaning hole 1242. The valve plate 21 is provided with a water passage hole 211 in communication with the water passage cavity 113. The driving assembly 3 is in transmission connection with the valve core assembly 2, and the driving assembly 3 is used for driving the valve plate 21 to rotate relative to the housing 1, so that the water passage hole 211 is in communication or isolation with the first water outlet hole 1241 and the first self-cleaning hole 1242 in turn.

[0054] The first water outlet 122 is used for connecting the water spraying assembly to spray the water flow to the user. The first self-cleaning port 123 is also used for connecting the water spraying assembly, but the water flow flowing into the water spraying assembly through the first self-cleaning port 123 is used for self-cleaning the water spraying assembly, improving the cleanliness of the water spraying assembly, and improving the problem of bacterial proliferation and scaling in the water spraying assembly.

[0055] It should be noted that when the first self-cleaning opening 123 supplies water flow to the water spraying assembly, the water path inside the water spraying assembly will be changed. For example, the water flow from the first self-cleaning opening 123 will trigger the valve inside the water spraying assembly, so that the water flow inside the water spraying assembly will not be sprayed to the user, but will be drained from another water outlet. When the first self-cleaning opening 123 no longer supplies water flow to the water spraying assembly, the above-mentioned valve will automatically restore, and then the first water outlet 122 can still spray water flow to the user when it supplies water flow to the water spraying assembly. Alternatively, in some other embodiments, the water flow from the first self-cleaning opening 123 is faster, which helps to quickly spray the residual water in the water spraying assembly from the water spraying assembly, and then the water spraying assembly moves to the working position to spray water flow to the user.

[0056] It can be understood that the valve plate 21 rotates along the sealing surface 124, that is, when the valve plate 21 rotates, the valve plate 21 still abuts against the sealing surface 124 and seals the first water outlet hole 1241 and the first self-cleaning hole 1242. When the valve plate 21 is not provided with the water passing hole 211, the valve plate 21 rotates by any angle relative to the shell 1, and the valve plate 21 will seal the first water outlet hole 1241 and the first self-cleaning hole 1242. When viewed in a direction perpendicular to the valve plate 21, the first water outlet hole 1241 and the first self-cleaning hole 1242 are at least partially located on the path of the water passing hole 211, so that when the valve plate 21 rotates to the projection of the water passing hole 211 partially overlaps the first water outlet hole 1241 or the first self-cleaning hole 1242, the water passing hole 211 communicates with the first water outlet hole 1241 or the first self-cleaning hole 1242; when the valve plate 21 rotates to the projection of the water passing hole 211 is spaced from the first water outlet hole 1241 or the first self-cleaning hole 1242, the water passing hole 211 is isolated from the first water outlet hole 1241 or the first self-cleaning hole 1242. That is, the water passing hole 211 communicates with or is isolated from the first water outlet hole 1241 and the first self-cleaning hole 1242 in turn, so that by rotating the valve plate 21, water flow can flow from the first water outlet 122 or the first self-cleaning opening 123. Alternatively, the valve plate 21 is a circular plate, and the sealing surface 124 is a circular flat surface.

[0057] In some embodiments, when the valve plate 21 rotates relative to the shell 1 to the first water draining angle, the water passing hole 211 simultaneously communicates with the first water outlet hole 1241 and the first self-cleaning hole 1242. Exemplarily, please refer to Figure 4 and Figure 5The shell 1 is provided with a first recess 1243 at the sealing surface 124, the first recess 1243 is communicated with the first water outlet hole 1241, and the first recess 1243 extends towards the first self-cleaning hole 1242. When the valve plate 21 is rotated to the first water draining angle relative to the shell 1, the projection of the first self-cleaning hole 1242 and the projection of the first recess 1243 both partially overlap the water passing hole 211 in the direction perpendicular to the valve plate 21. It can be understood that the minimum distance between the first self-cleaning hole 1242 and the first recess 1243 is smaller than the width of the water passing hole 211 along the movement track direction, so that when the valve plate 21 is rotated to the first water draining angle relative to the shell 1, the water passing hole 211 can be communicated with the first self-cleaning hole 1242 and the first recess 1243 at the same time, that is, the water flow flows out from the first water outlet 122 and the first self-cleaning hole 123 at the same time, so as to quickly drain the residual water in the water spraying assembly in advance, and then the water passing hole 211 is communicated with the first water outlet hole 1241, and the heated water flow is sprayed to the user, thereby improving the problem that the unheated water flow is sprayed to the user and improving the user experience.

[0058] Alternatively, when the water flow flows out from the first water outlet 122 and the first self-cleaning hole 123 at the same time, the water flow flowing into the water spraying assembly from the first self-cleaning hole 123 can stimulate the valve inside the water spraying assembly, so that the water flow in the water spraying assembly is no longer sprayed to the user, but drained from another water draining port. When the first self-cleaning hole 123 is no longer communicated with the water flow into the water spraying assembly, the above-mentioned valve automatically restores, and the water flow communicated into the water spraying assembly from the first water outlet 122 can still be sprayed to the user through the water spraying assembly.

[0059] In some embodiments, referring to Figure 4 and Figure 5 , along the movement track of the water passing hole 211 and along the direction of the first water outlet hole 1241 towards the first self-cleaning hole 1242, the width of the first recess 1243 gradually decreases. When the projection of the first recess 1243 partially overlaps the water passing hole 211, the area of the projection of the first recess 1243 overlapping the water passing hole 211 can be changed by rotating the valve plate 21 relative to the shell 1, so as to adjust the water flow size of the first water outlet 122 and adjust the water flow size sprayed by the water spraying assembly.

[0060] In some embodiments, referring to Figure 2 and Figure 3 , the valve core assembly 2 further comprises a transmission shaft 22 and an elastic member 23, the transmission shaft 22 is in transmission connection with the valve plate 21 and the driving assembly 3, the valve plate 21 can slide relative to the transmission shaft 22 along the direction parallel to the rotation axis of the valve plate 21, and the elastic member 23 is supported between the transmission shaft 22 and the valve plate 21. Thus, the elastic member 23 applies a pressure to the valve plate 21 towards the sealing surface 124, so that the valve plate 21 can seal the first water outlet hole 1241 and the first self-cleaning hole 1242, and the sealing effect is enhanced. Optionally, the elastic member 23 is a straight spring.

[0061] In some embodiments, referring to Figure 2 and Figure 3 , the valve core assembly 2 further comprises a second sealing ring 24 clamped between the transmission shaft 22 and the first shell 11. The transmission shaft 22 and the first shell 11 are sealed, and the drive assembly 3 is located outside the water passage 113, so that the drive assembly 3 does not need to be waterproofed, which is conducive to reducing the cost of the distribution valve 100. Optionally, the second sealing ring 24 is a rubber ring. In this embodiment, the transmission shaft 22 rotates relative to the first shell 11, so the second sealing ring 24 rotates to seal the transmission shaft 22 and the first shell 11. The second sealing ring 24 is preferably a “Y” type sealing ring.

[0062] In some embodiments, referring to Figures 2 to 4 , the shell 1 is further provided with a second water outlet 125 and a second self-cleaning port 126. The shell 1 is provided with a second water outlet hole 1244 and a second self-cleaning hole 1245 on the sealing surface 124. The second water outlet hole 1244 is in communication with the second water outlet 125, and the second self-cleaning hole 1245 is in communication with the second self-cleaning port 126. The valve plate 21 is further used to seal the second water outlet hole 1244 and the second self-cleaning hole 1245. The drive assembly 3 is used to drive the valve plate 21 to rotate relative to the shell 1, so that the water passage hole 211 is in communication or isolation with the second water outlet hole 1244 and the second self-cleaning hole 1245 in turn. The principle of the first water outlet hole 1241 and the first self-cleaning hole 1242 is the same as described above. The second water outlet 125 of this embodiment is used to communicate with a second water spraying assembly to spray water flow to the user; the second self-cleaning port 126 is also used to communicate with the second water spraying assembly to self-clean the second water spraying assembly. By rotating the valve plate 21, water flow can flow out from the second water outlet 125 or the second self-cleaning port 126.

[0063] In addition, the second water spraying assembly can have some same structural features as the first water spraying assembly. For example, the water flow flowing into the second water spraying assembly from the second self-cleaning port 126 can trigger the valve inside the second water spraying assembly, so that the water flow in the second water spraying assembly no longer sprays out to the user. The second water spraying assembly is installed at a different position from the first water spraying assembly, so as to spray water flow to the user at different angles or to different parts of the user. For example, the first water spraying assembly is used for hip washing, and the second water spraying assembly is used for female washing. The hip washing water spraying assembly is arranged at the rear side of the bowl of the intelligent toilet, and the female washing water spraying assembly is arranged at the front side of the bowl of the intelligent toilet. The female washing water spraying assembly can be arranged on the seat ring of the intelligent toilet.

[0064] In some embodiments, when the valve plate 21 rotates to the second drainage angle relative to the shell 1, the water passage hole 211 is in communication with the second water outlet hole 1244 and the second self-cleaning hole 1245 at the same time. Exemplarily, referring to Figure 4 andFigure 6 The shell 1 is provided with a second groove 1246 and a third groove 1247 at the sealing surface 124, the second groove 1246 is communicated with the second water outlet hole 1244, the third groove 1247 is communicated with the second self-cleaning hole 1245, the second groove 1246 extends towards the second self-cleaning hole 1245, and the third groove 1247 extends towards the second water outlet hole 1244. When the valve plate 21 rotates to the second water draining angle relative to the shell 1, the projection of the second groove 1246 and the projection of the third groove 1247 are both partially overlapped with the water passing hole 211 in the direction perpendicular to the valve plate 21. It can be understood that the minimum distance between the second groove 1246 and the third groove 1247 is less than the width of the water passing hole 211 along the direction of its movement track, so that when the valve plate 21 rotates to the second water draining angle relative to the shell 1, the water passing hole 211 can be communicated with the second groove 1246 and the third groove 1247 at the same time, that is, the water flow simultaneously flows out from the second water outlet 125 and the second self-cleaning hole 126, so as to quickly drain the residual water in the second water spraying assembly in advance, and then the water passing hole 211 is communicated with the second water outlet hole 1244, and the heated water flow is sprayed to the user, thereby improving the problem that the unheated water flow is sprayed to the user and improving the user experience.

[0065] Alternatively, when the water flow simultaneously flows out from the second water outlet 125 and the second self-cleaning hole 126, the water flow flowing into the second water spraying assembly from the second self-cleaning hole 126 can stimulate the valve inside the second water spraying assembly, so that the water flow in the second water spraying assembly is no longer sprayed to the user, but is drained from another water draining hole. When the second self-cleaning hole 126 is no longer communicated with the water flow into the second water spraying assembly, the above-mentioned valve automatically restores, and the water flow communicated into the second water spraying assembly from the second water outlet 125 can still be sprayed to the user through the second water spraying assembly.

[0066] In some embodiments, referring to Figure 4 and Figure 6 , the projection of the third groove 1247 at least partially overlaps with the second groove 1246 in the direction of the interval between the second groove 1246 and the rotation axis of the valve plate 21. That is, the third groove 1247 and the second groove 1246 are mutually overlapped in the direction of the track of the water passing hole 211, which is beneficial to increase the total area of the projection of the second groove 1246 and the third groove 1247 overlapping with the water passing hole 211, and further increase the water flow rate of the second water spraying assembly. Alternatively, the projection of the third groove 1247 completely overlaps with the second groove 1246 in the direction of the interval between the second groove 1246 and the rotation axis of the valve plate 21.

[0067] In some embodiments, referring to Figure 4 and Figure 6The widths of the second groove 1246 and the third groove 1247 are constant along the direction of the movement track of the water passage 211. The widths of the second groove 1246 and the third groove 1247 being constant, the angle of the valve plate 21 relative to the shell 1 is linearly related to the area of the projection of the second groove 1246 overlapping the water passage 211, so as to facilitate accurate control of the area of the projection of the second groove 1246 overlapping the water passage 211, that is, more accurate control of the flow of the second water outlet 125. Based on the same principle, the flow of the second self-cleaning outlet 126 can be more accurately controlled.

[0068] In some embodiments, referring to Figure 4 and Figure 6 , the shell 1 is provided with a fourth groove 1248 at the sealing surface 124, the fourth groove 1248 is in communication with the second water outlet hole 1244, and the fourth groove 1248 extends towards the second self-cleaning hole 1245. The width of the fourth groove 1248 gradually decreases along the movement track of the water passage 211 and along the direction of the second water outlet hole 1244 towards the second self-cleaning hole 1245. When the projection of the fourth groove 1248 overlaps the water passage 211, the area of the projection of the fourth groove 1248 overlapping the water passage 211 can be changed by rotating the valve plate 21 relative to the shell 1, so as to adjust the water flow size of the second water outlet 125 and adjust the water flow size of the water spraying assembly. Optionally, the second groove 1246, the fourth groove 1248 and the second water outlet hole 1244 are arranged in sequence along the direction of the movement track of the water passage 211.

[0069] In some embodiments, referring to Figure 1 and Figure 2 , the direction of the second water outlet 125 is arranged at an angle with the direction of the second water outlet hole 1244. During the process that the water flow in the water passage cavity 113 flows into the second water outlet 125 through the second water outlet hole 1244 and flows out of the second water outlet 125, the direction of the water flow changes, which is beneficial to buffer the water flow, so that the flow rate of the water flow finally flowing out of the second water outlet 125 is more stable, and is beneficial to reduce the water flow rate, so that the water flow sprayed by the second water spraying assembly to the user is more stable and the flow rate is more moderate, which is beneficial to improve the user experience.

[0070] In some embodiments, referring to Figure 1 and Figure 2 , the direction of the second self-cleaning outlet 126 is the same as the direction of the second self-cleaning hole 1245. During the process that the water flow in the water passage cavity 113 flows into the second self-cleaning outlet 126 through the second self-cleaning hole 1245 and flows out of the second self-cleaning outlet 126, the direction of the water flow does not change, which is beneficial to reduce the momentum loss of the water flow and enhance the washing effect of the water flow on the second water spraying assembly.

[0071] In a second aspect, the embodiments of the present application provide a smart toilet (not shown) comprising the distribution valve 100. The smart toilet has the structural features and beneficial effects of the distribution valve 100, which will not be repeated here.

[0072] In some embodiments, the smart toilet comprises a pressure reducing valve, a heater and the distribution valve 100 connected in sequence. The pressure reducing valve is connected to an external water supply, and the distribution valve 100 is connected to one or more water spraying assemblies. The pressure reducing valve and the heater can be further provided with a water tank, i.e. the smart toilet can be provided with a water tank to store water, or can not be provided with a water tank. When the smart toilet is provided with a water tank, a water pump is needed between the water tank and the heater to pump the water in the water tank to the heater.

[0073] The distribution valve 100 and the smart toilet of the embodiments of the present application are provided with the first self-cleaning port 123 in the shell 1, which can self-clean the water spraying assembly, improve the cleanliness of the water spraying assembly, and improve the problem of bacterial proliferation and scaling in the water spraying assembly. The water passage hole 211 can be connected to the first water outlet hole 1241 and the first self-cleaning hole 1242 at the same time, so as to quickly drain the residual water in the water spraying assembly in advance, and then the water passage hole 211 is connected to the first water outlet hole 1241, and the heated water flow is sprayed to the user, which improves the problem of spraying unheated water flow to the user, and improves the user experience. The second water outlet 125 and the second self-cleaning port 126 are further provided, which can be connected to a second water spraying assembly to spray water flow to the user at different angles or to different parts of the user.
