In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0040] Please refer to Figure 1 , the embodiment of the present application provides a water-using device, and the water-using device can be a shower device or other water-using devices.

[0041] Among them, the water-using device includes a valve core 100, and the valve core 100 can be used to regulate the on / off of the water flow and the water outlet size, so as to control the on / off of the water-using device and the water outlet size.

[0042] As an example, the water-using device is a shower device. The shower device can include a connected body and a plurality of water outlet devices. The water outlet devices can be a shower head, a rain shower head, or a water outlet faucet, etc. The water outlet devices can be connected to the body. A driving structure can be provided on the body. The valve core 100 can be arranged in the body. The driving structure can be connected to the valve core 100. The user can operate the driving structure to control the valve core 100, thereby controlling the on / off of the water outlet device and the water outlet size.

[0043] Please refer to Figures 2 to 4 , in some embodiments, the valve core 100 includes a housing 110 and a moving valve body 130.

[0044] Among them, the housing 110 is provided with an installation space 1131, a water inlet 1111, and a first water outlet 1133. Both the water inlet 1111 and the first water outlet 1133 communicate with the installation space 1131. The liquid entering the installation space 1131 through the water inlet 1111 can flow out from the first water outlet 1133. Among them, the liquid can refer to water.

[0045] The water inlet 1111 is provided on the bottom wall 111 of the housing 110, and the first water outlet 1133 is provided on the side wall 113 of the housing 110. Compared with the bottom water inlet and bottom water outlet method in the related art, the valve core 100 in the embodiment of the present application adopts bottom water inlet and side water outlet, which helps to reduce the turning angle of the liquid in the installation space 1131, thereby reducing the flow resistance of the liquid in the installation space 1131 and increasing the water flow rate of the first water outlet 1133.

[0046] As an example, the valve core 100 may include a side wall 113 and a bottom wall 111. The side wall 113 may adopt an annular structure to surround and form an installation space 1131. The bottom wall 111 may be connected to one end of the side wall 113. The water inlet 1111 is provided on the bottom wall 111, and the first water outlet 1133 is provided on the side wall 113.

[0047] The moving valve body 130 is movably arranged in the housing 110. The moving valve body 130 has a cut-off position and a conducting position. When the moving valve body 130 moves, it can make the water inlet 1111 and the installation space 1131 communicate or be cut off. Thus, the moving valve body 130 can have a conducting position and a cut-off position.

[0048] When the moving valve body 130 is in the cut-off position (as Figure 2 shown), the moving valve body 130 blocks the water inlet 1111. At this time, the moving valve body 130 closes the water inlet 1111, and the liquid cannot enter the installation space 1131 from the water inlet 1111.

[0049] When the moving valve body 130 is in the conducting position (as Figure 3 shown), the water inlet 1111 communicates with the installation space 1131. At this time, the moving valve body 130 opens the water inlet 1111, and the liquid can enter the installation space 1131 from the water inlet 1111.

[0050] The moving valve body 130 includes a first guiding surface 1313. When the moving valve body 130 is in the conducting position, the first guiding surface 1313 faces the water inlet 1111 and is used to guide the liquid flowing from the water inlet 1111 to the installation space 1131 to the first water outlet 1133. In this way, the liquid entering the installation space 1131 can flow to the first guiding surface 1313, and the first guiding surface 1313 can change the flow direction of the liquid, so that the liquid can flow in the direction of the first water outlet 1133, which helps the liquid to flow to the first outlet 1339 more quickly, reduces the flow resistance of the liquid in the installation space 1131, and increases the water flow rate of the first water outlet 1133.

[0051] It should be noted that the moving valve body 130 can also have a partially open position between the closed position and the open position. When the moving valve body 130 is in the partially open position, the water inlet 1111 can be partially in communication with the installation space 1131, so as to control the water inlet flow rate and thus control the water outlet flow rate.

[0052] Understandably, the moving valve body 130 can have one or more partially open positions. When the moving valve body 130 has multiple partially open positions, each partially open position can correspond to different communication areas between the water inlet 1111 and the installation space 1131, so as to more precisely control the water inlet flow rate and thus more precisely control the water outlet flow rate.

[0053] In some embodiments, the valve core 100 can further include a static valve body 150, and the static valve body 150 can be connected to the housing 110 and located within the installation space 1131.

[0054] The static valve body 150 can be provided with a first through hole 151 and a second through hole 153. Both the first through hole 151 and the second through hole 153 are in communication with the water inlet 1111. Liquid can enter the first through hole 151 and the second through hole 153 from the water inlet 1111, and then enter the installation space 1131 from the first through hole 151 and the second through hole 153.

[0055] When the moving valve body 130 is in the closed position, the moving valve body 130 blocks the first through hole 151 and the second through hole 153. At this time, the moving valve body 130 closes the first through hole 151 and the second through hole 153, and liquid cannot enter the installation space 1131 from the first through hole 151 and the second through hole 153.

[0056] When the moving valve body 130 is in the open position, both the first through hole 151 and the second through hole 153 are in communication with the installation space 1131. At this time, the moving valve body 130 opens the first through hole 151 and the second through hole 153. Liquid can flow to the installation space 1131 through both the first through hole 151 and the second through hole 153 simultaneously, increasing the number of flow channels for liquid to enter the installation space 1131, increasing the water inlet flow rate, and thus helping to increase the liquid pressure within the installation space 1131 and facilitating an increase in the water outlet flow rate and flow volume.

[0057] When the moving valve body 130 is in the open position, one of the first through hole 151 and the second through hole 153 can face the first guiding surface 1313. The first guiding surface 1313 is used to guide the liquid flowing to the installation space 1131 through the first through hole 151 or the second through hole 153 to the first water outlet 1133, so as to accelerate the liquid flow rate, reduce the liquid flow resistance, and increase the water outlet flow rate of the valve core 100.

[0058] As an example, the first guiding surface 1313 can be opposite to the first through hole 151. The first guiding surface 1313 is used to guide the liquid flowing through the first through hole 151 to the installation space 1131 towards the first water outlet 1133.

[0059] As another example, the first guiding surface 1313 can be opposite to the second through hole 153. The first guiding surface 1313 is used to guide the liquid flowing through the second through hole 153 to the installation space 1131 towards the first water outlet 1133.

[0060] In some embodiments, the housing 110 may further be provided with a second water outlet 1135 communicating with the installation space 1131, and the moving valve body 130 may further include a second guiding surface 1347.

[0061] Wherein, when the moving valve body 130 is in the conducting position, the first guiding surface 1313 is opposite to the first through hole 151 and is used to guide the liquid flowing through the first through hole 151 to the installation space 1131 towards the first water outlet 1133. The second guiding surface 1347 is opposite to the second through hole 153 and is used to guide the liquid flowing through the second through hole 153 to the installation space 1131 towards the second water outlet 1135. In this way, the two guiding surfaces (the first guiding surface 1313 and the second guiding surface 1347) can respectively guide the liquid flowing through the first through hole 151 and the second through hole 153 to the installation space 1131 towards the corresponding water outlets (the first water outlet 1133 or the second water outlet 1135), which helps to further accelerate the flow rate of the liquid, reduce the flow resistance of the liquid, and increase the water outlet flow rate of the valve core 100.

[0062] As an example, both the first water outlet 1133 and the second water outlet 1135 can be provided on the side wall 113 of the housing 110. Along the height direction of the valve core 100, the first water outlet 1133 and the first guiding surface 1313 can be at the same height, which helps the first guiding surface 1313 to guide the liquid to the first water outlet 1133 more smoothly. Similarly, the second water outlet 1135 and the second guiding surface 1347 can also be at the same height, which helps the second guiding surface 1347 to guide the liquid to the second water outlet 1135 more smoothly. Wherein, the height direction of the valve core 100 is generally from the static valve body 150 towards the moving valve body 130.

[0063] It should be noted that the first water outlet 1133 and the second water outlet 1135 can be at the same height of the housing 110, or can be at different heights of the housing 110 respectively. The first water outlet 1133 and the second water outlet 1135 can be symmetrically distributed or asymmetrically distributed.

[0064] In some embodiments, the moving valve body 130 may further be provided with a guiding flow channel 1335. One of the first guiding surface 1313 and the second guiding surface 1347 may be located within the guiding flow channel 1335, and the other may be located on the outer sidewall of the moving valve body 130. Thus, the outer wall structure of the moving valve body 130 can be fully utilized without the need to provide two flow channels within the moving valve body 130, which helps to reduce the size of the moving valve body 130 and thus can reduce the size of the valve core 100.

[0065] Wherein, when the moving valve body 130 is in the conducting position, the first through hole 151 or the second through hole 153 communicates with the guiding flow channel 1335. Thus, the liquid within the first through hole 151 or the second through hole 153 can directly enter the guiding flow channel 1335, and then, after being redirected by the guiding surface (the first guiding surface 1313 or the second guiding surface 1347) within the guiding flow channel 1335, flows towards the water outlet (the first water outlet 1133 or the second water outlet 1135). The liquid has a more accurate flow direction within the guiding flow channel 1335, which helps to accelerate the flow rate of the liquid.

[0066] As an example, when the moving valve body 130 is in the conducting position, the first through hole 151 may communicate with the guiding flow channel 1335, the second through hole 153 may directly communicate with the installation space 1131, and the first guiding surface 1313 may be located within the guiding flow channel 1335. Then, the liquid entering the guiding flow channel 1335 can be directed towards the first water outlet 1133. The second guiding surface 1347 may be located on the outer sidewall of the moving valve body 130.

[0067] As another example, when the moving valve body 130 is in the conducting position, the second through hole 153 may communicate with the guiding flow channel 1335, the first through hole 151 may directly communicate with the installation space 1131, and the second guiding surface 1347 may be located within the guiding flow channel 1335. Then, the liquid entering the guiding flow channel 1335 can be directed towards the second water outlet 1135. The first guiding surface 1313 may be located on the outer sidewall of the moving valve body 130.

[0068] For ease of explanation, the following description is given by taking the example where the first guiding surface 1313 is located within the guiding flow channel 1335, the second guiding surface 1347 is located on the outer sidewall of the moving valve body 130, and when the moving valve body 130 is in the conducting position, the first through hole 151 communicates with the guiding flow channel 1335.

[0069] In some embodiments, the guiding flow channel 1335 may have an inlet 1337 and an outlet 1339. The inlet 1337 is used to communicate with the first through hole 151 or the second through hole 153, and the outlet 1339 communicates with the installation space 1131. The liquid can enter the guiding flow channel 1335 through the inlet 1337, be directed towards the outlet 1339 after passing through the first guiding surface 1313, and then flow towards the first water outlet 1133 through the outlet 1339.

[0070] In some embodiments, the area of the outlet 1339 can be ≥ 18 mm² and ≤ 25 mm², so as to ensure that the outlet 1339 has a sufficiently large water outlet area, which helps to ensure that the outlet 1339 has a sufficiently large water flow rate, and thus can ensure that the first water outlet 1133 has a sufficiently large flow rate.

[0071] Among them, the area of the outlet 1339 can refer to the cross-sectional area. For example, when the shape of the outlet 1339 is circular, the area of the outlet 1339 can refer to the area of the circle. When the area of the outlet 1339 is rectangular, the area of the outlet 1339 can be the area of the rectangle. Or the outlet 1339 can also adopt other shapes, which can be specifically designed according to requirements.

[0072] As an example, the area of the outlet 1339 can be 18 mm², 19 mm², 20 mm², 25 mm² or other values in the range [18 mm², 25 mm²].

[0073] Preferably, the area of the outlet 1339 can be 20 mm², and the outlet 1339 can have a better water flow rate.

[0074] In some embodiments, the area of the outlet 1339 can be less than or equal to the area of the first water outlet 1133, which helps to prevent the housing 110 from blocking the liquid flowing out of the outlet 1339.

[0075] In some embodiments, the moving valve body 130 can include a moving seat 131 and a valve body 133. The moving seat 131 is movably located in the installation space 1131. The valve body 133 is connected to the moving seat 131 and is located between the moving seat 131 and the static valve body 150. In this way, splitting the moving valve body 130 into two structural parts, namely the moving seat 131 and the valve body 133, helps to reduce the manufacturing difficulty of the moving valve body 130, makes it easier to machine the guiding flow channel 1335, and also makes it easier to machine the first guiding surface 1313 and the second guiding surface 1347.

[0076] Among them, the guiding flow channel 1335 can be provided in the valve body 133.

[0077] The moving seat 131 can be provided with a guiding boss 1311 protruding into the guiding flow channel 1335. One of the first guiding surface 1313 and the second guiding surface 1347 is located on the guiding boss 1311, so that it can be easier to set the first guiding surface 1313 or the second guiding surface 1347 in the guiding flow channel 1335, reducing the processing difficulty.

[0078] As an example, the guiding flow channel 1335 includes two flow channels that are connected and arranged at an angle, and the two flow channels are respectively named the first section 1341 and the second section 1343. The inlet 1337 can be arranged at one end of the first section 1341 away from the second section 1343 for communicating with the first through hole 151. The outlet 1339 can be arranged at one end of the second section 1343 away from the first section 1341, and the outlet 1339 can communicate with the installation space 1131. The shape of the second section 1343 can be generally in the form of a groove structure. The second section 1343 has a notch on the side of the valve body 133 facing the moving seat 131. When the valve body 133 is connected to the moving seat 131, the moving seat 131 can cover the notch to close the notch, so that the liquid entering the second section 1343 can flow out through the outlet 1339 and cannot flow out through the notch.

[0079] It can be understood that there is a corner position at the connection between the first section 1341 and the second section 1343. The guiding boss 1311 can be inserted into the corner position from the notch, so that the guiding boss 1311 extends into the guiding flow channel 1335.

[0080] For the convenience of explanation, the following description is made taking the first guiding surface 1313 being located on the guiding boss 1311 as an example.

[0081] In some embodiments, the guiding boss 1311 can abut against the valve body 133, so that when the moving seat 131 moves, the valve body 133 can be driven to move synchronously through the guiding boss 1311 without setting other connection structures.

[0082] In some embodiments, the first guiding surface 1313 can adopt an arc surface, an inclined surface or a surface with other shapes.

[0083] As an example, the first guiding surface 1313 can adopt an arc surface, and the arc surface can be a concave arc. The two ends of the first guiding surface 1313 respectively face the water inlet 1111 and the first water outlet 1133. Thus, after entering the installation space 1131 through the liquid inlet 1111, the liquid changes direction after contacting the first guiding surface 1313 and flows towards the first water outlet 1133.

[0084] As another example, the first guiding surface 1313 can adopt an inclined surface. The inclined surface can be arranged at an angle with the moving plane of the moving valve body 130 and incline towards the side of the first water outlet 1133. The two ends of the first guiding surface 1313 respectively face the water inlet 1111 and the first water outlet 1133. Thus, after entering the installation space 1131 through the liquid inlet 1111, the liquid changes direction after contacting the first guiding surface 1313 and flows towards the first water outlet 1133.

[0085] In some embodiments, the second guiding surface 1347 can also adopt an arc surface, an inclined surface or a surface with other shapes.

[0086] As an example, the valve body 133 may include a main body and a diversion block 1345. The guiding flow channel 1335 may be provided in the main body. The diversion block 1345 may protrude from the outer side wall of the main body. The diversion block 1345 may be located on one side of the main body facing the second water outlet 1135, and the diversion block 1345 may be located on the side of the valve body 133 away from the static valve body 150. On the side of the diversion block 1345 facing the static valve body 150, the diversion block 1345 and the main body may be connected and transitioned through an inclined surface or an arc, so as to form a second diversion surface.

[0087] Please refer to Figures 5 to 6 , in some embodiments, the housing 110 may further be provided with a mounting hole 1151 communicating with the mounting space 1131. The water inlet 1111 and the mounting hole 1151 may be distributed at opposite ends of the housing 110.

[0088] The valve core 100 may further include a driving rod 170 and a hinge shaft 190. The driving rod 170 is connected to the hinge shaft 190. The hinge shaft 190 is located in the mounting hole 1151 and is connected to the housing 110. The driving rod 170 is connected to the moving valve body 130. The driving rod 170 can rotate around the axis of the hinge shaft 190 to drive the moving valve body 130 to move. Therefore, the moving valve body 130 can be driven to move by rotating the driving rod 170, and the operation is convenient.

[0089] Among them, the driving rod 170 rotates around the axis of the hinge shaft 190, which may mean that the hinge shaft 190 is fixed to the housing 110, the driving rod 170 is rotatably connected to the hinge shaft 190, and the driving rod 170 can rotate around the axis of the hinge shaft 190; it may also mean that the hinge shaft 190 is rotatably connected to the housing 110, the driving rod 170 is fixed to the hinge shaft 190, and the driving rod 170 and the hinge shaft 190 rotate synchronously around the axis of the hinge shaft 190.

[0090] In some embodiments, a connecting groove 1315 is provided on the side of the moving valve body 130 facing the mounting hole 1151. The end of the driving rod 170 may be provided with a connecting block 173. The connecting block 173 may be disposed in the connecting groove 1315 and abut against the groove side wall of the connecting groove 1315. Therefore, when the driving rod 170 rotates, it can push the groove side wall of the connecting groove 1315 to drive the moving valve body 130 to move. Specifically, the connecting groove 1315 may be provided on the side of the moving seat 131 away from the valve body 133.

[0091] The shape of the connecting groove 1315 may be designed according to requirements. For example, the shape of the connecting groove 1315 may be rectangular, oval, semicircular or other shapes. The shape of the connecting block 173 may be adapted to the shape of the connecting groove 1315 so that the connecting block 173 can be inserted into the connecting groove 1315.

[0092] In some embodiments, the housing 110 may further include an annular wall 115, and the annular wall 115 defines a mounting hole 1151.

[0093] Wherein, the annular wall 115 may be connected to a side of the side wall 113 of the housing 110 facing away from the bottom wall 111. The hinge shaft 190 may be connected to the annular wall 115.

[0094] The valve core 100 may further include a positioning member 210 and an elastic member 230. The driving rod 170 may be provided with a mounting groove 171. The positioning member 210 may be located in the mounting groove 171. The elastic member 230 may be abutted between the bottom wall of the mounting groove 171 and the positioning member 210. Thus, when the driving rod 170 rotates, the positioning member 210 may rotate synchronously with the driving rod 170, and the elastic member 230 may push the positioning member 210 so that the positioning member 210 always abuts against the annular wall 115.

[0095] As an example, the elastic member 230 may be a spring, and the positioning member 210 may be a stepped shaft. The spring may be sleeved on the positioning member 210 and abutted between the stepped surface of the positioning member 210 and the bottom wall of the mounting groove 171 to push the positioning member 210 to always abut against the annular wall 115. It can be understood that the elastic member 230 may also be an elastic rubber, an elastic silica gel or other elastic structural members.

[0096] The inner wall of the annular wall 115 may be provided with a first positioning groove 1153 and a second positioning groove 1155. The first positioning groove 1153 and the second positioning groove 1155 may be distributed on the rotation path of the positioning member 210, so that the positioning member 210 can rotate with the driving rod 170 and be inserted into the first positioning groove 1153 or the second positioning groove 1155.

[0097] As an example, one end of the positioning member 210 abutting against the annular wall 115 may adopt a conical structure, and the diameter may gradually increase from the end of the positioning member 210 abutting against the annular wall 115 towards the direction of the elastic member 230. The end face of the end of the positioning member 210 abutting against the annular wall 115 may adopt an arc surface to reduce the contact area with the annular wall 115, which helps the positioning member 210 to move more smoothly on the annular wall 115. For example, the arc surface may be a spherical surface.

[0098] When the moving valve body 130 is in the conducting position, the positioning member 210 may be inserted into the first positioning groove 1153, thereby preventing the moving valve body 130 from moving. The moving valve body 130 may be maintained in the conducting position, which helps the water-using device to maintain the water outlet state.

[0099] The moving valve body 130 is in the cut-off position, and the positioning member 210 is inserted into the second positioning groove 1155, so that the movement of the moving valve body 130 can be avoided. The moving valve body 130 can be kept in the cut-off position, which helps the water-using device to be kept in the water-off state.

[0100] In some embodiments, a third positioning groove may be provided on the inner wall of the annular wall 115 between the first positioning groove 1153 and the second positioning groove 1155. When the moving valve body 130 is in the partially open position, the positioning member 210 can be inserted into the third positioning groove. It can be understood that when there are multiple partially open positions, the number of third positioning grooves can also be multiple and they correspond one by one.

[0101] In some embodiments, a plurality of damping protrusions 1157 may protrude from the inner wall of the annular wall 115. The plurality of damping protrusions 1157 may be located between the first positioning groove 1153 and the second positioning groove 1155 and distributed on the rotation path of the positioning member 210. The damping protrusions 1157 can be used to increase the moving friction force of the positioning member 210. Thus, when the positioning member 210 rotates following the driving rod 170, it can rub against the damping protrusions 1157 to increase the moving friction force of the positioning member 210, which helps to improve the feel when operating the driving rod 170 and enhance the user experience.

[0102] Among them, the damping protrusions 1157 can be dot-shaped protrusions, strip-shaped protrusions or protrusions of other shapes.

[0103] As an example, the damping protrusions 1157 can be strip-shaped protrusions. The plurality of strip-shaped protrusions can be distributed along the rotation direction of the positioning member 210, so that the positioning member 210 can pass through the plurality of strip-shaped protrusions when moving, increasing the moving friction force of the positioning member 210. The length direction of the strip-shaped protrusion can be set at an angle with the tangent of the rotation direction of the positioning member 210 to increase the moving friction force of the positioning member 210. For example, the tangent of the rotation direction of the positioning member 210 can be perpendicular to the length direction of the strip-shaped protrusion.

[0104] In the spool 100 and water-using equipment according to the embodiments of the present application, the housing 110 is provided with an installation space 1131, a water inlet 1111 and a first water outlet 1133. The water inlet 1111 is provided on the bottom wall 111 of the housing 110, and the first water outlet 1133 is provided on the side wall 113 of the housing 110. The liquid entering the installation space 1131 through the water inlet 1111 can flow out from the first water outlet 1133. In this way, the spool 100 can intake water from the bottom and discharge water from the side, reducing the turning angle of the liquid, thereby reducing the flow resistance of the liquid and increasing the water discharge flow rate of the first water outlet 1133. The moving valve body 130 is movably arranged in the housing 110. When the moving valve body 130 moves to the cut-off position, the water inlet 1111 is closed, and the liquid cannot enter the installation space 1131 from the water inlet 1111; when the moving valve body 130 is in the conducting position, the water inlet 1111 is opened, and the liquid can enter the installation space 1131 from the water inlet 1111. The moving valve body 130 includes a first guiding surface 1313. When the moving valve body 130 is in the conducting position, the first guiding surface 1313 faces the water inlet 1111. The liquid entering the installation space 1131 can flow towards the first guiding surface 1313, and the first guiding surface 1313 can change the flow direction of the liquid, enabling the liquid to flow more rapidly towards the direction of the first water outlet 1133, reducing the flow resistance of the liquid, and further increasing the water discharge flow rate of the first water outlet 1133.

[0105] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention. In addition, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
