Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0028] See also Figure 1 , an embodiment of the present application provides a water-using device, which may be a shower device or other water-using devices.

[0029] The water-using device includes a valve core 100, and the valve core 100 can be used to control the on / off of water and the water output size of the water-using device.

[0030] As an example, the water-using device is a shower device, which may include a main body and a plurality of water outlet devices connected to each other, and the water outlet devices may be a shower head, a top spray or a water outlet faucet, etc. The water outlet device may be connected to the main body, and a driving member may be provided on the main body, and the driving member may control the on / off water and the water outlet size of the water outlet device. The valve core 100 may be arranged in the main body, and the driving member may be connected to the valve core 100. The user may operate the driving member to drive the internal structural member of the valve core 100 to move, thereby controlling the on / off water and the water outlet size of the water outlet device. The main body may also be used as a shelf to place bathing items.

[0031] See also Figures 2 to 4 In some embodiments, the valve core 100 includes a housing 110 , a valve body assembly 130 and a sealing ring 150 .

[0032] The housing 110 may be used to accommodate structural parts such as the valve body assembly 130 and the sealing ring 150 . The housing 110 may also be used to connect other structural parts to fix the valve core 100 . For example, the housing 110 may be connected to the main body.

[0033] The housing 110 is provided with a housing space 111, and a mounting port 113, a water inlet 115 and a water outlet 117 all connected to the housing space 111. The water inlet 115 can be used to connect a water inlet pipe, and the water outlet 117 can be used to connect a water outlet device. Liquid can enter the housing space 111 from the water inlet 115, then flow from the water outlet 117 to the water outlet device, and then flow out through the water outlet device to be used by the user. The liquid can refer to water.

[0034] The mounting port 113 can be used to mount a structural member. For example, the mounting port 113 can be used to mount a rocker arm 210. The rocker arm 210 can be connected to the valve body assembly 130. The rocker arm 210 swings to drive the valve body assembly 130 to move, thereby controlling the on / off of water and the amount of water output.

[0035] The housing 110 has a contact surface 119 between the installation opening 113 and the accommodating space 111 . For example, the contact surface 119 may be an inner wall surface of the accommodating space 111 .

[0036] The valve body assembly 130 is movably disposed in the accommodating space 111 for opening or covering the water inlet 115 , so that the movement of the valve body assembly 130 can control the on / off of water, the size of water outlet, etc.

[0037] As an example, the valve body assembly 130 may have a first position and a second position. When the valve body assembly 130 is in the first position (eg, Figure 2 As shown in FIG. 1 ), the valve body assembly 130 can cover the water inlet 115 to shut off the water. When the valve body assembly 130 is in the second position (as shown in FIG. Figure 3 As shown in FIG. 1 ), the valve body assembly 130 can open the water inlet 115 to achieve boiling water. It can be understood that the valve body assembly 130 can also move to the point where the water inlet 115 is partially connected to the accommodating space 111, so that the water inlet amount of the water inlet 115 can be adjusted to control the water outlet size of the valve core 100. For example, between the first position and the second position, the valve body assembly 130 can also have a third position. When the valve body assembly 130 is in the third position, the water inlet 115 is partially connected to the accommodating space 111.

[0038] The valve body assembly 130 is provided with an annular mounting groove 1313, a flow guide hole 1315, and a mounting surface 1311 arranged opposite to the abutting surface 119. The mounting surface 1311 can be arranged with a gap with the abutting surface 119.

[0039] The annular mounting groove 1313 is recessed in the mounting surface 1311, and the sealing ring 150 is sealingly disposed in the annular mounting groove 1313 and abuts against the abutting surface 119. In this way, the sealing ring 150 can seal the gap between the abutting surface 119 and the mounting surface 1311, which helps to prevent the liquid in the accommodating space 111 from seeping into the mounting port 113, thereby achieving static sealing between the valve body assembly 130 and the housing 110.

[0040] As an example, the annular mounting groove 1313 can be an annular groove and is arranged around the mounting opening 113. One side of the sealing ring 150 can abut against the inner side wall and the groove bottom wall of the annular mounting groove 1313, and the other side abuts against the abutting surface 119 of the housing 110, so that a static seal between the valve body assembly 130 and the housing 110 can be achieved.

[0041] The sealing ring 150 is provided with a first annular groove 151 , and the drainage hole 1315 communicates the first annular groove 151 with the accommodating space 111 , so that the liquid entering the accommodating space 111 can enter the first annular groove 151 through the drainage hole 1315 .

[0042] The sealing ring 150 , the abutting surface 119 and the mounting surface 1311 cooperate to form a second annular groove 170 . It can be understood that the second annular groove 170 can be a part of the accommodating space 111 , and the liquid entering the accommodating space 111 can enter the second annular groove 170 .

[0043] The sealing ring 150 is configured to abut against the abutting surface 119 under the pressure of the liquid in the first annular groove 151 and the second annular groove 170. In this way, the sealing ring 150 can always maintain the state of abutting against the abutting surface 119 under the action of the liquid pressure, thereby improving the dynamic sealing effect between the valve body assembly 130 and the abutting surface 119 when the valve body assembly 130 moves. In addition, it is also helpful to improve the situation where the sealing effect of the sealing ring 150 is affected by the process error or movement wear of the sealing ring 150, and further improve the sealing effect of the sealing ring 150. The embodiment of the present application can effectively improve the sealing performance between the valve body assembly 130 and the housing 110 and improve the water seepage in the installation port 113 by improving the static sealing effect and dynamic sealing effect of the sealing ring 150.

[0044] Specifically, the sealing ring 150 can be a flexible sealing ring, for example, the sealing ring 150 can be a rubber sealing ring, a silicone sealing ring or other flexible sealing rings. When the sealing ring 150 is installed, the sealing ring 150 can be compressed between the bottom wall of the first annular groove 151, the groove side wall and the abutting surface 119, and the sealing ring 150 can have a certain amount of compression, so that the sealing ring 150 is sealed between the first annular groove 151 and the abutting surface 119.

[0045] As the valve body assembly 130 moves, the sealing ring 150 moves synchronously with the valve body assembly 130, and the friction between the sealing ring 150 and the abutting surface 119 causes a certain amount of wear on the sealing ring 150. The liquid in the first annular groove 151 applies a first force along the first direction Y to the inner wall surface of the first annular groove 151, and the liquid in the second annular groove 170 can apply a second force along the opposite direction of the first force to the outer wall surface of the sealing ring 150. The first force can be greater than the second force, so that the second force can offset a part of the first force, and the first force that is not offset can push the sealing ring 150, so that the sealing ring 150 always remains in a state of abutting the abutting surface 119. In addition. Since the second force can offset a part of the first force, it helps to avoid the situation where the friction between the sealing ring 150 and the abutting surface 119 increases due to the large first force, helps to improve the wear of the sealing ring 150, and also helps the valve body assembly 130 move more smoothly. Among them, the first direction Y can be the direction from the mounting surface 1311 to the abutting surface 119.

[0046] In addition, since the first annular groove 151 and the second annular groove 170 are located close to each other, the static pressure in the first annular groove 151 and the static pressure in the second annular groove 170 are roughly the same, that is, the internal and external pressures of the valve body assembly 130 are roughly the same, which helps the valve body assembly 130 move more smoothly.

[0047] See also Figures 3 to 5 In some embodiments, the sealing ring 150 includes a first annular side wall 1511 and a second annular side wall 1513 opposite to each other, and the first annular side wall 1511 and the second annular side wall 1513 cooperate to form a first annular groove 151 .

[0048] The sealing ring 150 is configured such that under the pressure of the liquid in the first annular groove 151, the first annular side wall 1511 and the second annular side wall 1513 respectively abut against the groove side walls on both sides of the annular mounting groove 1313. In this way, the first annular side wall 1511 and the second annular side wall 1513 can always abut against the groove side walls on both sides of the annular mounting groove 1313, which helps to improve the sealing effect of the sealing ring 150.

[0049] As an example, the first annular groove 151 is disposed around the side of the sealing ring 150 away from the first direction Y, and the first annular groove 151 divides the side of the sealing ring 150 away from the first direction Y into a first annular side wall 1511 and a second annular side wall 1513. The liquid in the first annular groove 151 can push against the side walls on both sides of the first annular groove 151 (i.e., the first annular side wall 1511 and the second annular side wall 1513), so that the first annular side wall 1511 and the second annular side wall 1513 always abut against the groove side walls on both sides of the annular mounting groove 1313.

[0050] In some embodiments, the distance between the first annular side wall 1511 and the second annular side wall 1513 gradually decreases along the mounting surface 1311 toward the abutting surface 119 , so that the liquid in the first annular groove 151 can simultaneously apply a first force and a third force to the first annular inner wall surface and the second annular inner wall surface, which helps to improve the sealing effect of the sealing ring 150 .

[0051] As an example, the first annular groove 151 may be a V-shaped groove. The first annular sidewall 1511 may include a first annular inner wall surface, and the second annular sidewall 1513 may include a second annular inner wall surface. The first annular inner wall surface and the second annular inner wall surface may be two groove inner side surfaces of the first annular groove 151 .

[0052] Along the first direction Y, the first annular inner wall surface and the second annular inner wall surface gradually approach each other along the first direction Y and are connected by an arc. In this way, the first annular inner wall surface and the second annular inner wall surface are both inclined surfaces. When the liquid in the first annular groove 151 applies a force to the two inclined surfaces, the force applied by the liquid in the first annular groove 151 to the first annular inner wall surface and the second annular inner wall surface can be decomposed into a first force and two opposite third forces through force decomposition, and the two opposite third forces act on the first annular inner wall surface and the second annular inner wall surface respectively.

[0053] The first force pushes the sealing ring 150 along the first direction Y, so that the sealing ring 150 always abuts against the abutting surface 119. Two opposite third forces push the first annular inner wall surface and the second annular inner wall surface respectively, and the first annular side wall 1511 and the second annular side wall 1513 are opened, so that the first annular side wall 1511 and the second annular side wall 1513 always remain in a state of abutting against the groove side walls on both sides of the annular installation groove 1313, thereby improving the sealing effect of the sealing ring 150.

[0054] In some embodiments, the valve body assembly 130 may also be provided with a third annular groove 1317, and the third annular groove 1317 is recessed in the bottom wall of the annular mounting groove 1313, and the drainage hole 1315 connects the third annular groove 1317 and the accommodating space 111. In this way, the third annular groove 1317 can be connected to the first annular groove 151, and the liquid in the third annular groove 1317 can provide a more uniform liquid pressure along the entire annular side wall of the first annular groove 151, which helps to improve the tighter fit between the sealing ring 150 and the abutment surface 119, thereby improving the sealing effect between the sealing ring 150 and the abutment surface 119.

[0055] The groove width of the third annular groove 1317 may be smaller than the groove width of the annular installation groove 1313 , which helps to ensure that the sealing ring 150 can abut against the groove bottom wall of the annular installation groove 1313 .

[0056] In some embodiments, the width of the third annular groove 1317 can be smaller than the diameter of the drainage hole 1315. In this way, the liquid in the drainage hole 1315 flows faster when entering the third annular groove 1317, which helps the liquid to fill the first annular groove 151 more quickly, helps the first annular groove 151 to have a more stable static pressure, reduces the impact of instantaneous fluctuations in water pressure on the sealing ring 150, and helps to further improve the sealing effect of the sealing ring 150.

[0057] In some embodiments, the sealing ring 150 may include a sealing surface 153, which may abut against the abutting surface 119. The sealing surface 153 may be a raised arc surface, which helps to reduce the contact area between the sealing ring 150 and the abutting surface 119, thereby improving the sealing effect between the sealing ring 150 and the abutting surface 119.

[0058] The curvature of the sealing surface 153 can be designed according to requirements. For example, the sealing surface 153 can be a convex spherical surface.

[0059] As an example, the sealing ring 150 may include an integrally formed O-ring 150 and a V-ring 150 , and the sealing surface 153 may be located on the O-ring 150 . The V-ring 150 may be sealed in the annular mounting groove 1313 , and the first annular groove 151 may be provided on the V-ring 150 .

[0060] In some embodiments, the contact surface of the sealing ring 150 with the liquid in the first annular groove 151 is defined as a first surface 155 .

[0061] As an example, the first surface 155 may include the first annular inner wall surface, the second annular inner wall surface, and the arc surface connecting the first annular inner wall surface and the second annular inner wall surface in the above embodiment.

[0062] The contact surface of the sealing ring 150 with the liquid in the second annular groove 170 is the second surface 157. It can be understood that, since there is a certain gap between the abutting surface 119 and the mounting surface 1311, the annular surface of the sealing ring 150 located in the gap can be the second surface 157.

[0063] As an example, the second surface 157 may be a part of the sealing surface 153 in the above embodiment, that is, the first surface 155 may be a convex arc surface, so that the liquid in the second annular groove 170 can apply a second force to the second surface 157 .

[0064] The area of ​​the first surface 155 may be larger than the area of ​​the second surface 157 , so that the first force is larger than the second force, which helps the sealing ring 150 to always remain in contact with the abutting surface 119 .

[0065] In some embodiments, the area ratio of the first surface 155 to the second surface 157 is ≥1.1 and ≤1.2, that is, the area of ​​the first surface 155 is 10% to 20% larger than the area of ​​the second surface 157. In this way, controlling the area ratio of the first surface 155 to the second surface 157 within a suitable range helps the second force to better offset the first force, so that the sealing ring 150 can maintain the state of abutting against the abutting surface 119 under the action of the remaining first force, and the valve body assembly 130 can move more smoothly. For example, the second force can offset about 80% of the first force, and the remaining 20% ​​of the first force can keep the sealing ring 150 in a state of abutting against the abutting surface 119.

[0066] As an example, the area ratio of the first surface 155 and the second surface 157 may be 1.1, 1.12, 1.15, 1.2, or other values ​​in the interval [1.1, 1.2].

[0067] In some embodiments, the water inlet 115 and the water outlet 117 can be respectively located at opposite ends of the shell 110 along the direction from the installation surface 1311 to the abutment surface 119, and the water outlet 117 is located on the side wall of the shell 110. In this way, the liquid entering the accommodating space 111 through the water inlet 115 can flow out from the water outlet 117 on the side wall of the shell 110, which helps to reduce the flow resistance of the liquid.

[0068] Specifically, in the related art, the water inlet and the water outlet are located on the same side of the shell. If the liquid entering the accommodating space through the water inlet needs to flow to the water outlet, it needs to return to the water outlet along the original path after entering the accommodating space, which requires a sharp turn of about 180 degrees, resulting in a large flow resistance. In the embodiment of the present application, the liquid entering the accommodating space 111 through the water inlet 115 can flow directly out of the water outlet 117 on the side wall of the shell 110 without a sharp turn of 180 degrees, with a smaller turning angle and smaller flow resistance.

[0069] In some embodiments, the valve core 100 may further include a first valve body 190, which is connected to the housing 110 and is located in the accommodating space 111, and the valve body assembly 130 may abut against the first valve body 190 and be located between the abutting surface 119 and the first valve body 190. For example, the water inlet 115, the first valve body 190, the valve body assembly 130 and the installation port 113 may be distributed in sequence along the first direction Y. The first valve body 190 may be a ceramic part, for example, the first valve body 190 may be a static ceramic sheet.

[0070] The valve body assembly 130 is provided with a water flow channel 1331 , and the drainage hole 1315 connects the water flow channel 1331 and the first annular groove 151 . The liquid entering the water flow channel 1331 can enter the first annular groove 151 through the drainage hole 1315 .

[0071] The first valve body 190 may be provided with a first water passage 191 and a second water passage 193 , and both the first water passage 191 and the second water passage 193 may be communicated with the water inlet 115 .

[0072] The valve body assembly 130 moves to cover the first water outlet 191 and the second water outlet 193, or to connect the first water outlet 191 with the water flow channel 1331, and the second water outlet 193 with the accommodating space 111. In this way, two water outlets (the first water outlet 191 and the second water outlet 193) are arranged on the first valve body 190, and both water outlets are connected with the water inlet 115, forming two flow channels for liquid to enter the accommodating space 111. When the swing amplitude of the rocker arm 210 remains unchanged, it helps to increase the water inlet area and increase the static pressure of the liquid in the accommodating space 111, thereby increasing the water outlet flow rate of the water outlet 117 without increasing the volume of the valve core 100.

[0073] As an example, the first water passage 191 and the second water passage can be arranged oppositely and at intervals, and the bottom surface of the valve body assembly 130 away from the first direction Y can have a shielding surface. When the valve body assembly 130 is in the first position, the entrance of the first flow channel 1333 is located between the first water passage 191 and the second water passage 193, and the shielding surface shields the first water passage 191 and the second water passage 193, thereby blocking the water inlet 115. When the valve body assembly 130 is in the second position, the shielding surface opens the first water passage 191 and the second water passage 193, the first water passage 191 is connected to the water passage 1331, and the second water passage 193 is connected to the accommodating space 111, so that the water of the water inlet 115 can enter the accommodating space 111 through the two water passages at the same time, so as to increase the static pressure of the liquid in the accommodating space 111, thereby increasing the water outflow rate of the water outlet 117 without increasing the volume of the valve core 100.

[0074] The shapes of the first water outlet 191 and the second water outlet 193 can be designed according to the requirements. For example, the cross-sectional shape of the first water outlet 191 and the second water outlet 193 can be crescent-shaped.

[0075] In some embodiments, the cross-sectional area of ​​the water inlet 115 is greater than the sum of the cross-sectional areas of the first water outlet 191 and the second water outlet 193 , thereby accelerating the flow rate of the liquid and increasing the static pressure of the liquid in the accommodating space 111 , which helps to increase the water flow rate of the water outlet 117 without increasing the volume of the valve core 100 .

[0076] In some embodiments, the shell 110 is provided with two water outlets 117 , and both water outlets 117 can be arranged on the side wall of the shell 110 and are connected to the accommodating space 111 , so that the two water outlets 117 can discharge water at the same time, which helps to increase the water flow rate.

[0077] Among them, the two water outlets 117 can be connected to the same water outlet device. For example, the two water outlets 117 can be connected to a shower head, a top spray or a faucet, which helps to increase the water flow rate.

[0078] For the convenience of description, two water outlets 117 are defined as a first water outlet 1171 and a second water outlet 1173 .

[0079] In some embodiments, the valve body assembly 130 may include a first guide surface 1321, which may be located in the water flow channel 1331. The first guide surface 1321 is used to guide the liquid in the water flow channel 1331 to the first water outlet 1171, thereby reducing the resistance of the liquid in the water flow channel 1331 and accelerating the flow rate of the liquid in the water flow channel 1331.

[0080] As an example, the water flow channel 1331 may include a first flow channel 1333 and a second flow channel 1335 that are connected, and the first flow channel 1333 and the second flow channel 1335 may be arranged at an angle. The first flow channel 1333 may extend along the first direction Y and be used to connect to the first water outlet 191. The second flow channel 1335 is connected to the accommodating space 111 and may be directly connected to the first water outlet 191 as the valve body assembly 130 moves. The first guide surface 1321 may be an inclined surface and be inclined from the first valve body 190 to the direction of the first water outlet 1171. The first guide surface 1321 can be located at the corner of the first flow channel 1333 and the second flow channel 1335. In this way, when the first water outlet 191 is opened, the liquid enters the first flow channel 1333 and flows toward the first guide surface 1321. Since the first guide surface 1321 is inclined toward the first water outlet, the liquid flows into the second flow channel 1335 along the inclined direction of the first guide surface 1321, and then flows out through the first water outlet 1171, thereby reducing the resistance of the liquid at the corner of the first flow channel 1333 and the second flow channel 1335, which helps to increase the flow rate of the liquid in the water flow channel 1331.

[0081] It is understandable that the first guide surface 1321 may also be a concave arc surface or a surface of other shapes.

[0082] In some embodiments, the valve body assembly 130 may also be provided with a second guide surface 1339, and the second guide surface 1339 may be provided on the outer wall of the valve body assembly 130. The second guide surface 1339 is used to guide the liquid flowing into the accommodating space 111 through the second water outlet 193 to the second water outlet 1173. In this way, the second guide surface 1339 can guide the liquid flowing into the accommodating space 111 through the second water outlet 193 to the second water outlet 1173 more quickly, thereby improving the water outlet speed.

[0083] As an example, the outer wall surface of the valve body assembly 130 facing the second water outlet 1173 may be convexly provided with a guide protrusion 1337. Along the first direction Y, the guide protrusion 1337 and the second water outlet 1173 may be at substantially the same height on the valve core 100. On the side away from the first direction Y, the guide protrusion 1337 and the outer side wall of the valve body assembly 130 may pass through an arc surface to form a second guide surface 1339. When the valve body assembly 130 opens the second water outlet 193, the second guide surface 1339 and the second water outlet 193 may be opposite to each other, so that the liquid flowing into the accommodating space 111 through the second water outlet 193 may flow along the second guide surface 1339 to the second water outlet 1173, thereby increasing the water outlet speed.

[0084] It can be understood that the second guide surface 1339 can also be a slope. For example, on the side away from the first direction Y, the guide protrusion 1337 and the outer wall of the valve body assembly 130 can also be connected by a slope. The slope can be inclined from the first valve body 190 toward the direction of the second water outlet 1173 to guide the liquid to the second water outlet 1173.

[0085] In some embodiments, the valve body assembly 130 may further include a valve seat 131 and a second valve body 133 .

[0086] The second valve body 133 may be connected to the valve seat 131 , and the valve seat 131 may be used to hinge the rocker 210 . The rocker 210 swings to drive the valve seat 131 to move, thereby driving the second valve body 133 to move synchronously.

[0087] The second valve body 133 may be a ceramic component, for example, the second valve body 133 may be a movable ceramic piece.

[0088] The mounting surface 1311, the annular mounting groove 1313 and the drainage hole 1315 can all be arranged on the valve seat 131, and the second valve body 133 can be located between the valve seat 131 and the first valve body 190. For example, the water inlet 115, the first valve body 190, the second valve body 133, the valve seat 131 and the mounting port 113 can be distributed in sequence along the first direction Y.

[0089] The water flow channel 1331 and the blocking surface can be both provided on the second valve body 133. The movement of the valve seat 131 drives the second valve body 133 to move synchronously, so as to shield the first water outlet 191 and the second water outlet 193 through the second valve body 133, or to connect the first water outlet 191 with the water flow channel 1331, and the second water outlet 193 with the accommodating space 111. In this way, the present embodiment sets the valve seat 131 and the second valve body 133, and the second valve body 133 moves synchronously with the valve seat 131. When moving, it can open or shield the first water outlet 191 and the second water outlet 193 to control the on / off water and the water outlet size. The structure is relatively simple and easy to manufacture, thereby reducing the manufacturing cost of the valve core 100.

[0090] In some embodiments, a connection groove may be provided on the valve seat 131. A connection boss 1319 is also provided on the side of the valve seat 131 away from the connection groove. The first guide surface 1321 may be the end surface of the connection boss 1319 away from the first direction Y. The second valve body 133 may be provided with a plug hole, and the plug hole may be connected to the water flow channel 1331 and pass through the second valve body 133 along the first direction Y. The connection boss 1319 may be inserted into the plug hole, and the first guide surface 1321 may extend into the water flow channel 1331, so that the valve seat 131 may drive the second valve body 133 to move synchronously through the connection boss 1319.

[0091] In addition, the valve seat 131 and the second valve body 133 are separately provided, which helps to reduce the difficulty of processing the first guide surface 1321 , the water flow channel 1331 and the drainage hole 1315 .

[0092] In some embodiments, the guide protrusion 1337 may be located on the second valve body 133 to shorten the distance between the second guide surface 1339 and the second water outlet 193 , thereby helping to more quickly guide the liquid flowing into the accommodating space 111 through the second water outlet 193 to the second water outlet 1173 .

[0093] In some embodiments, the housing 110 may further be provided with a mounting portion 121 , which may be disposed between the water inlet 115 and the accommodating space 111 , and the first valve body 190 may be disposed on the mounting portion 121 to facilitate installation of the first valve body 190 .

[0094] The mounting portion 121 may be provided with a third water outlet 1211 and a fourth water outlet 1213. The third water outlet 1211 may be connected to the water inlet 115 and the first water outlet 191, and the fourth water outlet 1213 may be connected to the water inlet 115 and the second water outlet 193. The first water outlet 191 and the third water outlet 1211 may have the same shape, and the second water outlet 193 and the fourth water outlet 1213 may also have the same shape.

[0095] See also Figure 6 to Figure 7 In some embodiments, the valve core 100 may further include a rocker arm 210, which may be inserted into the mounting port 113 and hinged to the housing 110 and the valve body assembly 130. The rocker arm 210 swings to drive the valve body assembly 130 to move, so that the valve body assembly 130 can be driven to move by the rocker arm 210, which is easier to operate.

[0096] As an example, the valve core 100 may further include a rotating shaft 230. The rocker 210 may be provided with a first hole penetrating the rocker 210, and the inner side wall of the mounting port 113 may be provided with two opposite second holes. The rotating shaft 230 may be passed through the first hole and inserted into the two second holes, so that the rocker 210 is hinged to the housing 110. One end of the rocker 210 inserted into the mounting port 113 may be a hinged end, for example, one end of the rocker 210 inserted into the mounting port 113 is substantially cylindrical, and the axial direction is substantially perpendicular to the first direction Y, and the valve body assembly 130 may be provided with a connecting groove adapted to the shape of the hinged end, and the hinged end is rotatably inserted into the connecting groove, so that the rocker 210 can rotate around the rotating shaft 230, so as to move the groove wall of the connecting groove through the hinged end to drive the valve body assembly 130 to move.

[0097] In some embodiments, the valve core 100 may further include an adjusting member 250 and an elastic member 270. The rocker 210 may be provided with a third hole, and the third hole may be a blind hole. The adjusting member 250 may be inserted into the third hole movably along the axial direction of the third hole. The adjusting member 250 may be a stepped shaft provided with a stepped surface. The elastic member 270 may be sleeved on the adjusting member 250 and connected between the stepped surface and the bottom wall of the third hole. The inner side wall of the mounting port 113 may be provided with at least two positioning holes 1131, and one end of the adjusting member 250 away from the bottom wall of the third hole may move between the two positioning holes 1131 as the rocker 210 swings, so as to be inserted into one positioning hole 1131, and the elastic force of the elastic member 270 may push against the adjusting member 250 to fix the adjusting member 250 in the positioning hole 1131, so that the valve body assembly 130 may be positioned at a desired position.

[0098] As an example, the two positioning holes 1131 are defined as a first positioning hole and a second positioning hole, and when the adjusting member 250 is inserted into the first positioning hole as the rocker 210 swings, the valve body assembly 130 is in the first position. When the adjusting member 250 is inserted into the second positioning hole as the rocker 210 swings, the valve body assembly 130 is in the second position.

[0099] The end of the adjusting member 250 away from the bottom wall of the third hole may have an arc surface, which helps the adjusting member 250 to more easily locate the positioning hole 1131 .

[0100] It is understandable that there may be a third positioning hole, a fourth positioning hole, a fifth positioning hole, etc. between the first positioning hole and the second positioning hole to adjust the connection area between the water inlet 115 and the accommodating space 111 , thereby controlling the water inlet area of ​​the water inlet 115 .

[0101] In some embodiments, the inner side wall of the mounting opening 113 may further be provided with a strip protrusion 1133, and the strip protrusion 1133 may be located between two adjacent positioning holes 1131. The extension direction of the strip protrusion 1133 may be arranged at an angle to the moving direction of the adjusting member 250, so as to increase the friction between the adjusting member 250 and the strip protrusion 1133, and improve the hand feeling when the rocker 210 swings.

[0102] It can be understood that between two adjacent positioning holes 1131 , the number of the strip-shaped protrusions 1133 can be one or more, and the number of the more can be two or more.

[0103] In the valve core 100 and the water inlet device provided in the embodiment of the present application, the housing 110 has an abutting surface 119 between the mounting port 113 of the housing 110 and the accommodating space 111. The valve body assembly 130 is movably arranged in the accommodating space 111, and has a mounting surface 1311 opposite to the abutting surface 119, the annular mounting groove 1313 is recessed in the mounting surface 1311, and the sealing ring 150 is sealingly arranged in the annular mounting groove 1313 and abuts against the abutting surface 119, so that the sealing ring 150 can be sealed between the valve body assembly 130 and the abutting surface 119, which helps to prevent the liquid in the accommodating space 111 from penetrating into the mounting port 113, thereby improving the static sealing effect. A first annular groove 151 is arranged around the sealing ring 150, and the drainage hole 1315 on the valve body assembly 130 can connect the first annular groove 151 and the accommodating space 111 to facilitate the liquid to enter the first annular groove 151; the sealing ring 150, the abutting surface 119 and the mounting surface 1311 cooperate to form a second annular groove 170 that can accommodate liquid, and the sealing ring 150 is configured to abut against the abutting surface 119 under the pressure of the liquid in the first annular groove 151 and the second annular groove 170. In this way, the sealing ring 150 can always maintain a state of abutting against the abutting surface 119, thereby improving the dynamic sealing effect of the sealing ring 150 when the valve body assembly 130 moves, and also helping to improve the situation where the sealing effect of the sealing ring 150 is affected by process errors or movement wear of the sealing ring 150.

[0104] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
