In this specification, the schematic representations 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.

[0043] 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.

[0044] Among them, the water-using device includes a valve core 100, and the valve core 100 can be used to control the opening / closing of the water-using device and the water output size.

[0045] As an example, the water-using device is a shower device, which may include a connected main body and a plurality of water outlet devices. The water outlet devices may be shower heads, overhead showers or water faucets, etc. The water outlet devices can be connected to the main body, and a driving member may be provided on the main body. The driving member can control the opening / closing of the water outlet device and the water output size. The valve core 100 can be arranged inside the main body, and the driving member can be connected to the valve core 100. The user can operate the driving member to drive the structural members inside the valve core 100 to move, so as to control the opening / closing of the water outlet device and the water output size. The main body can also be used as a storage rack to place bathing items.

[0046] Please refer to 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.

[0047] Among them, the housing 110 can be used to accommodate structural members such as the valve body assembly 130 and the sealing ring 150. The housing 110 can also be used to connect other structural members to fix the valve core 100. For example, the housing 110 can be connected inside the main body.

[0048] An accommodation space 111 is provided inside the housing 110, as well as an installation port 113, a water inlet 115 and a water outlet 117 that are all communicated with the accommodation space 111. The water inlet 115 can be used to connect the water inlet pipe, and the water outlet 117 can be used to connect the water outlet device. Liquid can enter the accommodation 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 for the user to use. Among them, the liquid can refer to water.

[0049] The installation port 113 can be used to install structural members. For example, the installation port 113 can be used to install the rocker 210. The rocker 210 can be connected to the valve body assembly 130. The rocker 210 swings to drive the valve body assembly 130 to move, so as to control the opening / closing of the water and the water output size.

[0050] Between the installation port 113 and the accommodation space 111, the housing 110 has an abutting surface 119. For example, the abutting surface 119 can be the inner wall surface of the accommodation space 111.

[0051] The valve body assembly 130 is movably arranged inside the accommodation space 111 and is used to open or shield the water inlet 115. Thus, the movement of the valve body assembly 130 can control the opening / closing of the water, the water output size, etc.

[0052] As an example, the valve body assembly 130 can have a first position and a second position. When the valve body assembly 130 is in the first position (as Figure 2 shown), the valve body assembly 130 can shield the water inlet 115 to achieve water shut-off. When the valve body assembly 130 is in the second position (as Figure 3As shown, the valve body assembly 130 can open the water inlet 115 to realize boiling water. It can be understood that the valve body assembly 130 can also move to a position where the water inlet 115 communicates with the accommodation space 111, so as to adjust the water inflow of the water inlet 115 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 communicates with the accommodation space 111.

[0053] The valve body assembly 130 is provided with an annular mounting groove 1313, a drainage hole 1315, and a mounting surface 1311 disposed opposite to the abutting surface 119. Among them, the mounting surface 1311 can be arranged with a gap from the abutting surface 119.

[0054] The annular mounting groove 1313 is recessed in the mounting surface 1311. The sealing ring 150 is hermetically arranged 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 accommodation space 111 from seeping into the mounting port 113, so as to realize the static seal between the valve body assembly 130 and the housing 110.

[0055] As an example, the annular mounting groove 1313 can be an annular groove and is arranged around the mounting port 113. One side of the sealing ring 150 can abut against the inner side wall and the bottom wall of the annular mounting groove 1313, and the other side abuts against the abutting surface 119 of the housing 110, so as to realize the static seal between the valve body assembly 130 and the housing 110.

[0056] The sealing ring 150 is provided with a first annular groove 151. The drainage hole 1315 communicates the first annular groove 151 with the accommodation space 111. In this way, the liquid entering the accommodation space 111 can enter the first annular groove 151 through the drainage hole 1315.

[0057] 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 accommodation space 111, and the liquid entering the accommodation space 111 can enter the second annular groove 170.

[0058] 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, 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 helps to improve the situation where the sealing effect of the sealing ring 150 is affected by the manufacturing process error or movement wear of the sealing ring 150, further improving the sealing effect of the sealing ring 150. By improving the static sealing effect and dynamic sealing effect of the sealing ring 150 in the embodiments of the present application, the sealing performance between the valve body assembly 130 and the housing 110 can be effectively improved, and the situation of water seepage in the installation port 113 can be improved.

[0059] 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 rubber sealing ring or other flexible sealing rings. When installing the sealing ring 150, the sealing ring 150 can be compressed between the bottom wall of the first annular groove 151, the side wall of the groove and the abutting surface 119. 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.

[0060] 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 exerts a first acting force along the first direction Y on the inner wall surface of the first annular groove 151. The liquid in the second annular groove 170 can exert a second acting force along the direction opposite to the first acting force on the outer wall surface of the sealing ring 150. The first acting force can be greater than the second acting force, so that the second acting force can offset a part of the first acting force, and the un-offset first acting force can push against the sealing ring 150, keeping the sealing ring 150 always in the state of abutting against the abutting surface 119. In addition, since the second acting force can offset a part of the first acting force, it helps to avoid the situation where the frictional force between the sealing ring 150 and the abutting surface 119 increases due to the large first acting force, helps to improve the wear situation of the sealing ring 150, and also helps the valve body assembly 130 to move more smoothly. Wherein, the first direction Y can be the direction from the mounting surface 1311 to the abutting surface 119.

[0061] In addition, since the positions of the first annular groove 151 and the second annular groove 170 are close, the static pressure in the first annular groove 151 and the static pressure in the second annular groove 170 are approximately the same, that is, the internal and external pressures of the valve body assembly 130 are approximately the same, which helps the valve body assembly 130 to move more smoothly.

[0062] Please refer to Figures 3 to 5, in some embodiments, the sealing ring 150 includes opposite first annular side walls 1511 and second annular side walls 1513, and the first annular side walls 1511 and the second annular side walls 1513 cooperate to form a first annular groove 151.

[0063] The sealing ring 150 is configured such that under the pressure of the liquid within the first annular groove 151, the first annular side walls 1511 and the second annular side walls 1513 respectively abut against the groove side walls on both sides of the annular mounting groove 1313. In this way, the first annular side walls 1511 and the second annular side walls 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.

[0064] As an example, the first annular groove 151 is disposed around the side of the sealing ring 150 facing away from the first direction Y, and the first annular groove 151 divides the side of the sealing ring 150 facing away from the first direction Y into the first annular side walls 1511 and the second annular side walls 1513. The liquid within 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 walls 1511 and the second annular side walls 1513), causing the first annular side walls 1511 and the second annular side walls 1513 to always abut against the groove side walls on both sides of the annular mounting groove 1313.

[0065] In some embodiments, the distance between the first annular side walls 1511 and the second annular side walls 1513 gradually decreases in the direction from the mounting surface 1311 to the abutting surface 119. Thus, the liquid within the first annular groove 151 can simultaneously apply a first acting force and a third acting 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.

[0066] As an example, the first annular groove 151 can be a V-shaped groove. The first annular side wall 1511 can include a first annular inner wall surface, and the second annular side wall 1513 can include a second annular inner wall surface. The first annular inner wall surface and the second annular inner wall surface can be the two inner side surfaces of the first annular groove 151.

[0067] 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 arc-connected. Thus, both the first annular inner wall surface and the second annular inner wall surface are inclined surfaces. When the liquid within the first annular groove 151 applies a force to the two inclined surfaces, through the decomposition of the force, the acting forces applied by the liquid within the first annular groove 151 to the first annular inner wall surface and the second annular inner wall surface can be respectively decomposed into a first acting force and two opposite third acting forces, and the two opposite third acting forces act on the first annular inner wall surface and the second annular inner wall surface respectively.

[0068] Among them, the first acting force pushes against 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 acting forces respectively push against the first annular inner wall surface and the second annular inner wall surface, and the first annular side wall 1511 and the second annular side wall 1513 open, so that the first annular side wall 1511 and the second annular side wall 1513 always maintain the state of respectively 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.

[0069] In some embodiments, the valve body assembly 130 may further be provided with a third annular groove 1317, the third annular groove 1317 is recessed in the bottom wall of the annular installation groove 1313, and the drainage hole 1315 communicates the third annular groove 1317 and the accommodation space 111. In this way, the third annular groove 1317 can communicate with 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 make the sealing ring 150 and the abutting surface 119 fit more tightly, and improves the sealing effect between the sealing ring 150 and the abutting surface 119.

[0070] Among them, the groove width of the third annular groove 1317 can 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 bottom wall of the annular installation groove 1313.

[0071] In some embodiments, the groove width of the third annular groove 1317 can be smaller than the diameter of the drainage hole 1315. In this way, when the liquid in the drainage hole 1315 enters the third annular groove 1317, the flow rate increases, which helps the liquid to fill the first annular groove 151 more quickly, helps to have a more stable static pressure in the first annular groove 151, reduces the impact on the sealing ring 150 caused by the instantaneous fluctuation of the water pressure, and helps to further improve the sealing effect of the sealing ring 150.

[0072] In some embodiments, the sealing ring 150 may include a sealing surface 153, the sealing surface 153 can abut against the abutting surface 119, and the sealing surface 153 can be a convex 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.

[0073] Among them, the radian of the sealing surface 153 can be designed according to requirements. For example, the sealing surface 153 can adopt a convex spherical surface.

[0074] As an example, the sealing ring 150 may include an integrally formed O-shaped sealing ring 150 and a V-shaped sealing ring 150, and the sealing surface 153 may be located on the O-shaped sealing ring 150. The V-shaped sealing ring 150 can be sealingly arranged in the annular installation groove 1313, and the first annular groove 151 can be arranged on the V-shaped sealing ring 150.

[0075] In some embodiments, the contact surface between the sealing ring 150 and the liquid within the first annular groove 151 is defined as the first surface 155.

[0076] 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 embodiments.

[0077] The contact surface between the sealing ring 150 and the liquid within the second annular groove 170 is the second surface 157. It can be understood that due to a certain gap between the abutting surface 119 and the mounting surface 1311, the annular surface of the sealing ring 150 located within this gap can be the second surface 157.

[0078] As an example, the second surface 157 may be a part of the sealing surface 153 in the above embodiments, that is, the first surface 155 may adopt a convex arc surface, so that the liquid within the second annular groove 170 can exert a second acting force on the second surface 157.

[0079] The area of the first surface 155 may be larger than the area of the second surface 157, so that the first acting force can be greater than the second acting force, which helps the sealing ring 150 to always remain in a state of abutting against the abutting surface 119.

[0080] 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 acting force to better offset the first acting force, enabling the sealing ring 150 to remain in a state of abutting against the abutting surface 119 under the action of the remaining first acting force, and also enabling the valve body assembly 130 to move relatively smoothly. For example, the second acting force can offset approximately 80% of the first acting force, and the remaining 20% of the first acting force can keep the sealing ring 150 always in a state of abutting against the abutting surface 119.

[0081] As an example, the area ratio of the first surface 155 to the second surface 157 can be 1.1, 1.12, 1.15, 1.2 or other values within the interval [1.1, 1.2].

[0082] In some embodiments, the water inlet 115 and the water outlet 117 may be respectively located at opposite ends of the housing 110 along the direction from the mounting surface 1311 to the abutting surface 119, and the water outlet 117 is located on the side wall of the housing 110. In this way, the liquid entering the accommodation space 111 through the water inlet 115 can flow out from the water outlet 117 on the side wall of the housing 110, which helps to reduce the flow resistance of the liquid.

[0083] Specifically, in the related art, the water inlet and the water outlet are located on the same side of the housing. If the liquid entering the accommodating space through the water inlet needs to flow to the water outlet, it needs to return along the original path to the water outlet after entering the accommodating space, and it needs to make a large 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 directly flow out from the water outlet 117 on the side wall of the housing 110 without making a large turn of 180 degrees, with a smaller turning angle and a smaller flow resistance.

[0084] In some embodiments, the valve core 100 may further include a first valve body 190. The first valve body 190 is connected to the housing 110 and is located in the accommodating space 111. The valve body assembly 130 can abut against the first valve body 190 and is 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 mounting port 113 can be sequentially distributed along the first direction Y. Among them, the first valve body 190 can be a ceramic part. For example, the first valve body 190 can be a static porcelain piece.

[0085] The valve body assembly 130 is provided with a water flow passage 1331. The diversion hole 1315 communicates the water flow passage 1331 and the first annular groove 151. The liquid entering the water flow passage 1331 can enter the first annular groove 151 through the diversion hole 1315.

[0086] The first valve body 190 can be provided with a first water passing port 191 and a second water passing port 193. Both the first water passing port 191 and the second water passing port 193 can communicate with the water inlet 115.

[0087] The valve body assembly 130 moves to shield the first water passing port 191 and the second water passing port 193, or to communicate the first water passing port 191 with the water flow passage 1331 and the second water passing port 193 with the accommodating space 111. In this way, two water passing ports (the first water passing port 191 and the second water passing port 193) are provided on the first valve body 190, and both water passing ports communicate with the water inlet 115, forming two flow paths for the liquid to enter the accommodating space 111. Without changing the swing amplitude of the rocker 210, it helps to increase the water inlet area and increase the static pressure of the liquid in the accommodating space 111, so that the water flow rate of the water outlet 117 can be increased without increasing the volume of the valve core 100.

[0088] As an example, the first water inlet 191 and the second water inlet can be arranged opposite to each other with a gap therebetween, and the bottom surface of the valve body assembly 130 facing away from the first direction Y can have a shielding surface. When the valve body assembly 130 is in the first position, the inlet of the first flow channel 1333 is located between the first water inlet 191 and the second water inlet 193, and the shielding surface shields the first water inlet 191 and the second water inlet 193, thereby blocking the water inlet from the water inlet 115. When the valve body assembly 130 is in the second position, the shielding surface opens the first water inlet 191 and the second water inlet 193, the first water inlet 191 communicates with the water flow channel 1331, and the second water inlet 193 communicates with the accommodation space 111. Thus, the water from the water inlet 115 can enter the accommodation space 111 through the two water inlets simultaneously, so as to increase the hydrostatic pressure of the liquid in the accommodation space 111, and thus the water outlet flow rate of the water outlet 117 can be increased without increasing the volume of the valve core 100.

[0089] Wherein, the shapes of the first water inlet 191 and the second water inlet 193 can be designed according to requirements. For example, the cross-sectional shapes of the first water inlet 191 and the second water inlet 193 can be crescent-shaped.

[0090] In some embodiments, the cross-sectional area of the water inlet 115 is larger than the sum of the cross-sectional areas of the first water inlet 191 and the second water inlet 193, so as to accelerate the flow rate of the liquid, increase the hydrostatic pressure of the liquid in the accommodation space 111, and contribute to increasing the water outlet flow rate of the water outlet 117 without increasing the volume of the valve core 100.

[0091] In some embodiments, the housing 110 is provided with two water outlets 117, and both of the two water outlets 117 can be arranged on the side wall of the housing 110 and communicate with the accommodation space 111. Thus, the two water outlets 117 can discharge water simultaneously, which helps to increase the water outlet flow rate.

[0092] Wherein, both of the two water outlets 117 can be connected to the same water outlet device. For example, both of the two water outlets 117 can communicate with a shower head, an overhead shower or a water outlet faucet, which helps to increase a larger water outlet flow rate.

[0093] For the convenience of description, the two water outlets 117 are respectively defined as a first water outlet 1171 and a second water outlet 1173.

[0094] In some embodiments, the valve body assembly 130 can include a first flow guiding surface 1321, and the first flow guiding surface 1321 can be located in the water flow channel 1331. The first flow guiding surface 1321 is used to guide the liquid in the water flow channel 1331 to the first water outlet 1171, so as to reduce the resistance of the liquid in the water flow channel 1331 and accelerate the flow rate of the liquid in the water flow channel 1331.

[0095] 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.

[0096] It is understandable that the first guide surface 1321 may also be a concave arc surface or a surface of other shapes.

[0097] 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.

[0098] 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.

[0099] Understandably, the second diversion surface 1339 can also be an inclined surface. For example, on the side facing away from the first direction Y, the guiding protrusion 1337 and the outer sidewall of the valve body assembly 130 can also be connected by an inclined surface, and the inclined surface can be inclined from the first valve body 190 towards the second water outlet 1173 to direct the liquid towards the second water outlet 1173.

[0100] In some embodiments, the valve body assembly 130 may further include a valve seat 131 and a second valve body 133.

[0101] Among them, the second valve body 133 can be connected to the valve seat 131, and the valve seat 131 can be used to hinge the rocker 210. The rocker 210 swings to drive the valve seat 131 to move and drive the second valve body 133 to move synchronously.

[0102] The second valve body 133 can be a ceramic part. For example, the second valve body 133 can be a moving ceramic piece.

[0103] The mounting surface 1311, the annular mounting groove 1313, and the drainage hole 1315 can all be provided on the valve seat 131. 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.

[0104] The water flow channel 1331 and the shielding surface can both be provided on the second valve body 133. The valve seat 131 moves to drive the second valve body 133 to move synchronously, so as to shield the first water passing port 191 and the second water passing port 193 through the second valve body 133, or to connect the first water passing port 191 and the water flow channel 1331, and connect the second water passing port 193 and the accommodating space 111. Thus, in this embodiment, by providing the valve seat 131 and the second valve body 133, the second valve body 133 moves synchronously with the valve seat 131, and can open or shield the first water passing port 191 and the second water passing port 193 during movement to control the opening / closing of water and the size of water output. The structure is relatively simple, easy to manufacture, and reduces the manufacturing cost of the valve core 100.

[0105] In some embodiments, a connecting groove can be provided on the valve seat 131. A connecting boss 1319 also protrudes from the side of the valve seat 131 facing away from the connecting groove. The first diversion surface 1321 can be the end surface of the connecting boss 1319 facing away from the first direction Y. The second valve body 133 can be provided with a plugging hole, and the plugging hole can communicate with the water flow channel 1331 and penetrate through the second valve body 133 along the first direction Y. The connecting boss 1319 can be inserted into the plugging hole, and the first diversion surface 1321 can extend into the water flow channel 1331, so that the valve seat 131 can drive the second valve body 133 to move synchronously through the connecting boss 1319.

[0106] 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 .

[0107] 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 .

[0108] 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 .

[0109] 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.

[0110] See also Figures 6 to 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.

[0111] 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.

[0112] 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 in an axially movable manner along the third hole. The adjusting member 250 may be a stepped shaft and is provided with a stepped surface. The elastic member 270 may be sleeved on the adjusting member 250 and is grounded between the stepped surface and the bottom wall of the third hole. At least two positioning holes 1131 may be provided on the inner side wall of the mounting port 113. One end of the adjusting member 250 facing 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 of the positioning holes 1131. 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, thereby positioning the valve body assembly 130 at a desired position.

[0113] As an example, the two positioning holes 1131 are respectively defined as a first positioning hole and a second positioning hole. When the adjusting member 250 is inserted into the first positioning hole as the rocker 210 swings, the valve body assembly 130 is in a 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 a second position.

[0114] Wherein, one end of the adjusting member 250 facing away from the bottom wall of the third hole may be an arc surface, which helps the adjusting member 250 to be more easily inserted into the positioning hole 1131.

[0115] It can be understood that there may also 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 communication area between the water inlet 115 and the accommodating space 111, thereby controlling the water inlet area of the water inlet 115.

[0116] In some embodiments, a strip-shaped protrusion 1133 may also be provided on the inner side wall of the mounting port 113, and the strip-shaped protrusion 1133 may be located between two adjacent positioning holes 1131. The extending direction of the strip-shaped protrusion 1133 may be set at an angle to the moving direction of the adjusting member 250 to increase the friction force between the adjusting member 250 and the strip-shaped protrusion 1133 and improve the feel when the rocker 210 swings.

[0117] It can be understood that between two adjacent positioning holes 1131, the number of the strip-shaped protrusions 1133 may be one or multiple, and multiple may be two or more.

[0118] In the spool valve 100 and the water inlet device provided by the embodiments of the present application, between the installation port 113 and the accommodation space 111 of the housing 110, the housing 110 has an abutting surface 119. The valve body assembly 130 is movably disposed in the accommodation space 111 and has an installation surface 1311 opposite to the abutting surface 119. An annular installation groove 1313 is recessed in the installation surface 1311, and the sealing ring 150 is hermetically disposed in the annular installation groove 1313 and abuts against the abutting surface 119. In this way, 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 accommodation space 111 from seeping into the installation port 113 and improves the static sealing effect. The sealing ring 150 is provided with a first annular groove 151, and the drainage hole 1315 on the valve body assembly 130 can communicate the first annular groove 151 and the accommodation space 111 to facilitate the liquid to enter the first annular groove 151; the sealing ring 150, the abutting surface 119 and the installation surface 1311 cooperate to form a second annular groove 170 that can accommodate the liquid. 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, which improves the dynamic sealing effect of the sealing ring 150 when the valve body assembly 130 moves, and also helps to improve the situation where the sealing effect of the sealing ring 150 is affected by the manufacturing process error or movement wear of the sealing ring 150.

[0119] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose 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.
