Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and in particular to switching valves and water outlet devices. Background Technology

[0002] In a water outlet device with multiple outlet channels, a switching valve is used to change the on / off state of each channel. The switching valve controls the on / off state of each outlet channel by pressing a button; one outlet channel corresponds to one button. When the target outlet channel is in the open state, the other outlet channels must be in the closed state. Therefore, there is a linkage between the multiple buttons; when one button is pressed, the others must switch to the open state. In actual operation, the force is only applied to the button that needs to be pressed, resulting in a less than smooth switching motion. Summary of the Invention

[0003] Therefore, it is necessary to provide a switching valve and water outlet device to address the problem of insufficient smoothness of press-to-switch operation. Not only can the elastic component adapt to the movement of the linkage conversion component and undergo elastic deformation, but the swing component will also adapt to the movement of the linkage conversion component through its own movement, thereby improving the smoothness of press-to-switch operation.

[0004] A switching valve, comprising:

[0005] The valve body is provided with an inlet channel and multiple outlet channels that are all connected to the inlet channel. The valve body is provided with multiple push-button valve cores, and the multiple push-button valve cores correspond one-to-one with the multiple outlet channels, which are used to control the selective conduction between the inlet channel and the multiple outlet channels.

[0006] The valve body is also provided with a linkage conversion component, a swing component, and an elastic component. The linkage conversion component includes a rotating part and a plurality of cantilever arms arranged at intervals along the first circumferential direction on the rotating part. The rotating part is hinged to the valve body. The rotating part is provided with an elastic component, and the elastic deformation direction of the elastic component is parallel to the axial direction corresponding to the first circumferential direction. One end of the elastic component protrudes from the rotating part and slidably abuts against the swing component. The swing component is assembled on the valve body by means of a hinge constraint.

[0007] Each of the multiple cantilever arms corresponds to one of the multiple push-button valve cores. When one of the push-button valve cores is switched to the open position, it will cause the free end of the corresponding cantilever arm to be pressed down and the free ends of the other cantilever arms to be raised. The raised free ends can cause the corresponding push-button valve core to be switched to the closed position.

[0008] In one embodiment, a limiting recess is provided at the position on the swing member that abuts against the elastic component, and one end of the elastic component that abuts against the swing member slides in the limiting recess.

[0009] In one embodiment, the switching valve includes at least three push-button valve cores, each push-button valve core is arranged at intervals around the rotating part along the first circumferential direction, the free end of each cantilever is located on the pressing path of a push-button valve core, the limiting recess is a groove structure with a polygonal cross-section, and each corner of the limiting recess points to each push-button valve core.

[0010] In one embodiment, the swing member includes a limiting part and a plurality of abutment arms connected to the limiting part. The limiting part is mounted on the valve body by means of hinge constraint. The limiting recess is formed on the limiting part. The fixed ends of each abutment arm are respectively located on each side of the limiting recess. The free ends of each abutment arm respectively point to the gap space between two adjacent push-type valve cores. Each abutment arm has a passing rib on the surface facing away from the limiting recess. Each passing rib extends along the length direction of the abutment arm.

[0011] In one embodiment, the switching valve includes three push-button valve cores, which are respectively arranged at the three corners of a triangle. The limiting recess is a groove structure with a triangular cross-section, and the three corners of the limiting recess point to the three push-button valve cores respectively.

[0012] In one embodiment, the portion of the swing member used to cooperate with the valve body to form a hinge constraint is a spherical cap protrusion. The valve body is provided with a spherical cap groove. The spherical cap protrusion abuts against the spherical cap groove and can rotate within the spherical cap groove to form a hinge constraint.

[0013] In one embodiment, a funnel-shaped groove is provided on the valve body at a position for cooperating with the rotating part to form a hinge constraint. The bottom of the funnel-shaped groove is spherical. The rotating part includes a round-headed cone inserted in the funnel-shaped groove. The round head shape of the round-headed cone is consistent with the spherical shape of the bottom of the funnel-shaped groove. The taper of the round-headed cone is smaller than the taper of the funnel-shaped groove. The elastic force of the elastic component is arranged along the axial direction of the round-headed cone.

[0014] In one embodiment, the elastic component includes a compression spring and a positioning pin. The round-headed cone has an opening formed at its tail end in a pressing groove. The depth direction of the pressing groove is consistent with the height direction of the round-headed cone. The compression spring is installed in the pressing groove. The positioning pin is inserted into the compression spring. One end of the positioning pin protrudes from the opening of the pressing groove and slidably presses against the swing member.

[0015] In one embodiment, the valve body is provided with a baffle plate, which together with the valve body defines a water inlet chamber. Each water outlet channel is formed on the side of the baffle plate away from the water inlet chamber. The baffle plate is provided with a plurality of water passage holes, which respectively connect the water inlet chamber and the plurality of water outlet channels. The water inlet chamber is connected to the water inlet channels.

[0016] Each of the push-button valve cores is installed at each of the water passage holes, and the linkage conversion element is located in the water inlet chamber.

[0017] In one embodiment, the push-button valve core passes sequentially through the water outlet channel, the water passage hole, and the water inlet chamber along the pressing direction;

[0018] The push-button valve core has a first sealing part, a second sealing part, and a third sealing part arranged sequentially in its pressing direction. When the push-button valve core is in the closed position, the second sealing part blocks the water passage hole. When the push-button valve core is in the open position, the second sealing part is offset from the water passage hole. The valve body is also provided with a first sealing hole and a second sealing hole at positions corresponding to each push-button valve core. When the push-button valve core is pressed, the first sealing part slides in the first sealing hole, and the third sealing part slides in the second sealing hole.

[0022] The above solution provides a switching valve and a water outlet device, which can press a suitable push-button valve core as needed to connect the target water outlet channel with the water inlet channel. When a push-button valve core is pressed, other push-button valve cores are adjusted to the closed position by the raised cantilever under the linkage action of the linkage conversion component. During this process, not only does the elastic component deform to adapt to the movement of the linkage conversion component, but the swing component also moves relative to the valve body, and the end of the elastic component slides on the swing component, allowing the linkage conversion component to switch smoothly and improving the smoothness of operation during the switching process.

[0043] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] In some embodiments of this application, a switching valve 10 is provided, such as... Figure 1 As shown, it includes: valve body 11.

[0045] like Figure 2 and Figure 14 As shown, the valve body 11 is provided with an inlet channel 114 and a plurality of outlet channels 115 that are all connected to the inlet channel 114. The valve body 11 is provided with a plurality of push-button valve cores 12, and the plurality of push-button valve cores 12 correspond one-to-one with the plurality of outlet channels 115, for controlling the selective conduction of the inlet channel 114 and the plurality of outlet channels 115.

[0046] Further as Figure 2 As shown, the valve body 11 also includes a linkage conversion component 13, a swing component 14, and an elastic component 15. Figures 4 to 6 As shown, the linkage conversion component 13 includes a rotating part 131 and a plurality of cantilever arms 132 arranged at intervals along the first circumferential direction on the rotating part 131. In... Figure 6 In the illustrated embodiment, the direction indicated by arrow N1 is the first circumferential direction. The rotating part 131 and the valve body 11 are hinged together. The rotating part 131 is provided with an elastic component 15, and the elastic deformation direction of the elastic component 15 is parallel to the axial direction corresponding to the first circumferential direction. One end of the elastic component 15 protrudes from the rotating part 131 and slidably abuts against the swing member 14. The swing member 14 is mounted on the valve body 11 by means of a hinge.

[0047] Each of the multiple cantilever arms 132 corresponds to one of the multiple push-button valve cores 12. When one of the push-button valve cores 12 is switched to the open position, it will cause the free end of the corresponding cantilever arm 132 to be pressed down and the free ends of the other cantilever arms 132 to be raised. The raised free ends can cause the corresponding push-button valve core 12 to be switched to the closed position.

[0048] In use, the appropriate push-button valve core 12 can be pressed as needed to connect the target water outlet channel 115 and the water inlet channel 114. When one push-button valve core 12 is pressed, other push-button valve cores 12 will be adjusted to the closed position by the raised cantilever 132 under the linkage action of the linkage conversion member 13. During this process, not only will the elastic component 15 deform to adapt to the movement of the linkage conversion member 13, but the swing member 14 will also move relative to the valve body 11. The end of the elastic component 15 will slide on the swing member 14, so that the linkage conversion member 13 can switch smoothly and improve the smoothness of operation during the switching process.

[0049] like Figure 2 As shown, the hinge constraint described in this application refers to the ability of two features to rotate spatially around a certain reference point, while the degrees of freedom for relative movement between the two features in all directions are restricted. Specifically, as shown in... Figure 2 In the embodiment shown, the linkage conversion element 13 can swing relative to the valve body 11 in a three-dimensional space, and the linkage conversion element 13 always maintains an interaction force with the valve body 11 and the two will not separate.

[0050] In some embodiments, the valve body 11 and the rotating part 131 are fitted together to form a ball hinge structure, and the oscillating member 14 and the valve body 11 are fitted together to form a ball hinge structure. When the position of the oscillating member 14 abutted by the elastic component 15 changes, the oscillating member 14 is tilted and rotates relative to the valve body 11 due to the force applied by the elastic component 15 to the oscillating member 14. The oscillating member 14 tilts to the side on which the force applied by the elastic component 15 to the oscillating member 14 is biased.

[0051] Furthermore, such as Figures 4 to 6 As shown, in some embodiments, the free end of the cantilever 132 is located on the pressing path of the press-type valve core 12. When the press-type valve core 12 is pressed, the press-type valve core 12 will press down the corresponding cantilever 132.

[0052] A protrusion 1322 can also be provided on the free end of the cantilever 132 at the position where it is pressed by the push-type valve core 12, so that the cantilever 132 and the push-type valve core 12 are in point contact or line contact, so as to minimize the possibility of interference caused by the push-type valve core 12 to the rotation of the linkage conversion component 13.

[0053] like Figures 3 to 6 As shown, in some embodiments, the push-button valve core 12 includes a spindle 121 and a seal disposed on the outer periphery of the spindle 121. The free end of the cantilever 132 is provided with a notch 1321, the spindle 121 is located in the notch 1321, and protrusions 1322 are distributed around the notch 1321 and are used to abut against the seal.

[0054] In some embodiments, such as Figure 2 and Figure 3 As shown, the elastic force of the elastic component 15 passes through the rotation center of the rotating part 131. While pressing against the swing member 14, the elastic component 15 also provides a force to the linkage conversion member 13, and this force passes through the rotation center of the rotating part 131, thereby ensuring that the rotating part 131 stably presses against the valve body 11.

[0055] Furthermore, such as Figure 5 and Figure 7 As shown, in some embodiments, a limiting recess 1411 is provided on the swing member 14 at the position abutting against the elastic component 15, and one end of the elastic component 15 that abuts against the swing member 14 slides in the limiting recess 1411, and the limiting recess 1411 limits the sliding range of the elastic component 15.

[0056] In actual use, such as Figure 4 As shown, when a push-button valve core 12 is in the open position, the linkage conversion element 13 rotates relative to the valve body 11 and tilts towards the push-button valve core 12. During the tilting process, the elastic component 15 tilts synchronously, causing the elastic component 15 to displace relative to the swinging component 14. Subsequently, the end of the elastic component 15 that abuts against the swinging component 14 slides in the limiting recess 1411. Finally, the elastic component 15 slides to the appropriate position in the limiting recess 1411, adapting to the tilting orientation and angle of the linkage conversion element 13 at this time. When the position of the swinging component 14 that is abutted by the elastic component 15 changes, the orientation of the external force on the swinging component 14 changes, thus causing it to swing to adapt to the change in force.

[0057] like Figure 4 and Figure 5 As shown, in some embodiments, the tilt direction of the linkage conversion member 13 relative to the valve body 11 is opposite to the tilt direction of the swing member 14 relative to the valve body 11. For example, if the linkage conversion member 13 tilts to the left relative to the valve body 11, the elastic component 15 tilts to the left simultaneously, and the position on the swing member 14 that is abutted by the elastic component 15 is shifted to the left, so the left side of the swing member 14 is lifted, and the swing member 14 tilts to the right relative to the valve body 11.

[0058] In some embodiments, such as Figure 4 and Figure 5 As shown, the switching valve 10 includes at least three push-button valve cores 12, each push-button valve core 12 being arranged at intervals around the rotating part 131 along the first circumferential direction. The free end of each cantilever 132 is located on the pressing path of a push-button valve core 12. The limiting recess 1411 is a groove structure with a polygonal cross-section, and each corner of the limiting recess 1411 points to each push-button valve core 12.

[0059] When a push-button valve core 12 is pressed down, the free end of the corresponding cantilever 132 is pressed down, and the linkage conversion member 13 tilts relative to the valve body 11. The elastic component 15 tilts synchronously with the linkage conversion member 13, and slides to the corner of the limiting recess 1411 pointing to the aforementioned push-button valve core 12. Then, the corner is lifted up, and the swing member 14 tilts relative to the valve body 11.

[0060] When switching the pressed valve core 12, the end of the elastic component 15 that abuts against the swing member 14 slides along the edge of the limiting recess 1411. For example, if the cross-section of the limiting recess 1411 is triangular, the end of the elastic component 15 that abuts against the swing member 14 slides along the three sides of the triangle.

[0061] In some embodiments, such as Figure 7 and Figure 8 As shown, the swing member 14 includes a limiting part 141, and a limiting recess 1411 is formed on the limiting part 141. The limiting part 141 is assembled on the valve body 11 by means of hinge constraint.

[0062] Furthermore, such as Figure 7 and Figure 8 As shown, in some embodiments, the swing member 14 further includes a plurality of abutment arms 142, each connected to the limiting portion 141. The fixed ends of each abutment arm 142 are located on different sides of the limiting recess 1411, and the free ends of each abutment arm 142 point to different gaps between two adjacent push-button valve cores 12. Each abutment arm 142 has a guide rib 1421 on its surface facing away from the limiting recess 1411, and each guide rib 1421 extends along the length direction of the abutment arm 142.

[0063] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the corner of the limiting recess 1411 with a polygonal cross-section points exactly to the space between two adjacent abutting arms 142. When the elastic component 15 abuts at a certain corner of the limiting recess 1411, the over-positioning ribs 1421 on the adjacent abutting arms 142 on both sides of the corner abut with the valve body 11.

[0064] When switching the pressed push-type valve core 12, the forces acting on the swing element 14, elastic component 15, and linkage conversion element 13 change as the switching process progresses. Assuming... Figure 9As shown, in the initial state, the elastic component 15 is pressed against the left side of the swing member 14. In this state, when other push-button valve cores 12 are pressed, as the pressing force F1 causes the linkage conversion member 13 to change its tilt direction, the elastic component 15 gradually slides on the swing member 14. As... Figure 9 and Figure 10 As shown, before the end of the elastic component 15 that abuts against the swing member 14 slides along one side of the limiting recess 1411 past the position of the over-positioning rib 1421, the deformation of the elastic component 15 gradually increases. Figure 10 and Figure 11 As shown, once the end of the elastic component 15 that abuts against the swing member 14 slides along one side of the limiting recess 1411 past the position of the over-positioning rib 1421, the swing member 14 will tilt to the right under the action of the elastic component 15, and the elastic component 15 will release energy.

[0065] like Figures 9 to 11 As shown, the over-position rib 1421 is equivalent to a support point between the swing member 14 and the valve body 11, and the swing member 14 rotates with this support point as the rotation center.

[0066] Furthermore, in some embodiments, the shape of the space on the valve body 11 for accommodating the swing member 14 is similar to the shape of the swing member 14.

[0067] Specifically in one embodiment, such as Figure 4 and Figure 5 As shown, the switching valve 10 includes three push-button valve cores 12, which are respectively arranged at the three corners of a triangle. The limiting recess 1411 is a groove structure with a triangular cross-section, and the three corners of the limiting recess 1411 point to the three push-button valve cores 12 respectively.

[0068] like Figure 2 , Figure 4 and Figure 8 As shown, in some embodiments, the portion of the swing member 14 that cooperates with the valve body 11 to form a hinge constraint is a spherical cap protrusion 1412. The valve body 11 has a spherical cap groove, and the spherical cap protrusion 1412 abuts against the spherical cap groove. The spherical cap protrusion 1412 can rotate within the spherical cap groove to form a hinge constraint. When the swing member 14 rotates relative to the valve body 11 under the action of the elastic component 15, the spherical cap protrusion 1412 rotates within the spherical cap groove.

[0069] In some embodiments, such as Figure 7 and Figure 8 As shown, the limiting recess 1411 and the spherical cap protrusion 1412 are respectively formed on two opposing surfaces of the swing member 14. The limiting recess 1411 is located on the surface of the swing member 14 facing the linkage conversion member 13.

[0070] Specifically in one embodiment, such as Figure 7 and Figure 8 As shown, a limiting recess 1411 and a spherical cap protrusion 1412 are provided on the limiting part 141. The spherical cap protrusion 1412 and the over-positioning rib 1421 are located on the same side of the swing member 14.

[0071] In one specific embodiment, such as Figures 4 to 8 As shown, the switching valve 10 includes three push-button valve cores 12, which are respectively arranged at the three corners of an equilateral triangle. The two adjacent cantilever arms 132 are arranged at 120°, and the two adjacent abutment arms 142 are arranged at 120°.

[0072] Furthermore, such as Figure 2 , Figures 4 to 6 As shown, in some embodiments, the valve body 11 has a funnel-shaped groove 1121 at a position for cooperating with the rotating part 131 to form a hinge constraint, and the bottom of the funnel-shaped groove 1121 is spherical. The rotating part 131 includes a round-headed cone 1311 inserted into the funnel-shaped groove 1121. The round head shape of the round-headed cone 1311 is consistent with the spherical shape of the bottom of the funnel-shaped groove 1121, and the taper of the round-headed cone 1311 is smaller than the taper of the funnel-shaped groove 1121. The elastic force of the elastic component 15 is arranged along the axial direction of the round-headed cone 1311.

[0073] like Figure 2 As shown, when the linkage conversion element 13 is pressed to one side, the cantilever 132 will eventually stop in a certain state under the clamping of the push-button valve core 12 and the valve body 11. The tilt angle of the linkage conversion element 13 is mainly limited by the cantilever 132. After tilting, the height line of the round-headed cone 1311 of the linkage conversion element 13 is set at an angle with the central axis of the funnel-shaped groove 1121, ensuring that there is an interaction force between each cantilever 132 and the corresponding push-button valve core 12, avoiding the push-button valve core 12 from being suspended and water flowing through.

[0074] like Figures 4 to 6 As shown, in one embodiment, multiple cantilever arms 132 are evenly distributed around the round-headed cone 1311 along a first circumferential direction, and the axis corresponding to the first circumferential direction is the height line of the round-headed cone 1311. The elastic force of the elastic component 15 is located on the height line of the round-headed cone 1311.

[0075] Specifically, in some embodiments, such as Figure 2 and Figure 3As shown, the elastic component 15 includes a compression spring 151 and a positioning pin 152. The rotating part 131 is provided with a pressing groove 133. The compression spring 151 is inserted into the pressing groove 133, and the depth direction of the pressing groove 133 is consistent with the elastic deformation direction of the compression spring 151. The positioning pin 152 is inserted into the compression spring 151, and one end of the positioning pin 152 protrudes from the opening of the pressing groove 133 and slidably presses against the swing member 14.

[0076] Optionally, the elastic component 15 can also be other elastic devices, as long as its elastic deformation direction and elastic force meet the aforementioned limitations, and one end of the elastic component 15 protruding outside the rotating part 131 can slide against the swing member 14.

[0077] like Figure 2 and Figure 5 As shown, in one embodiment, the locating pin 152 is slidably abutted against the limiting recess 1411.

[0078] Furthermore, in some embodiments, such as Figure 2 and Figure 3 As shown, the round-headed cone 1311 has an opening at its tail, forming a pressure groove 133. The depth of the pressure groove 133 is aligned with the height of the round-headed cone 1311. The compression spring 151 is installed within the pressure groove 133, and the positioning pin 152 is inserted into the compression spring 151. When the linkage conversion component 13 tilts, the compression spring 151 and the positioning pin 152 tilt synchronously.

[0079] like Figure 4 and Figure 5 As shown, in some embodiments, the linkage conversion member 13 and the swing member 14 are arranged sequentially along the height direction of the round-headed cone 1311. The tail of the round-headed cone 1311 is the end closest to the swing member 14.

[0080] Furthermore, such as Figures 4 to 6 As shown, in some embodiments, the outer diameter of the end of the round-headed cone 1311 near the swing member 14 gradually decreases, which facilitates relative rotation between the swing member 14 and the linkage conversion member 13, and there is no interference between the two.

[0081] Furthermore, in some embodiments, such as Figure 2 and Figure 3As shown, the valve body 11 is provided with a partition 113, which together with the valve body 11 defines a water inlet chamber 116. Each water outlet channel 115 is formed on the side of the partition 113 away from the water inlet chamber 116. The partition 113 is provided with a plurality of water passage holes 1131, which respectively connect the water inlet chamber 116 and the plurality of water outlet channels 115. The water inlet chamber 116 is connected to the water inlet channel 114.

[0082] Each of the push-button valve cores 12 is installed at each of the water passage holes 1131, and the linkage conversion element 13 is located in the water inlet chamber 116.

[0083] Multiple push-button valve cores 12 control the opening and closing of each water passage 1131, allowing the water inlet channel 114 to selectively connect with a certain water outlet channel 115. In addition, the linkage conversion element 13 is located in the water inlet chamber 116, making full use of the space in the water inlet chamber 116 to reduce the thickness of the switching valve 10 in the pressing direction.

[0084] Specifically in some embodiments, such as Figure 2 and Figure 14 As shown, the valve body 11 includes a valve seat 111 and a valve cover 112. A partition 113 is disposed within the valve seat 111, and a water outlet channel 115 is formed within the valve seat 111. After the valve cover 112 is installed on the valve seat 111, the space between the valve cover 112 and the partition 113 forms the water inlet chamber 116. The linkage conversion element 13 is located between the valve cover 112 and the partition 113.

[0085] The partition 113 and the valve seat 111 can be integrally formed.

[0086] In some embodiments, such as Figure 3 As shown, the push-button valve core 12 passes through the water outlet channel 115, the water passage hole 1131 and the water inlet chamber 116 in sequence along the pressing direction.

[0087] The push-button valve core 12 has a first sealing part 122, a second sealing part 123, and a third sealing part 124 arranged sequentially in its pressing direction. When the push-button valve core 12 is in the closed position, the second sealing part 123 seals the water passage hole 1131. When the push-button valve core 12 is in the open position, the second sealing part 123 is offset from the water passage hole 1131. The valve body 11 also has a first sealing hole 117 and a second sealing hole 118 at positions corresponding to each push-button valve core 12. When the push-button valve core 12 is pressed, the first sealing part 122 slides in the first sealing hole 117, and the third sealing part 124 slides in the second sealing hole 118. The first sealing hole 117 is formed on the channel wall of the water outlet channel 115, and the second sealing hole 118 is formed on the cavity wall of the water inlet chamber 116.

[0088] The cross-sectional area of ​​the second sealing hole 118 is larger than that of the first sealing hole 117, and the cross-sectional area of ​​the water passage hole 1131 is larger than that of the second sealing hole 118.

[0089] When the push-button valve core 12 is pressed and the water passage 1131 is opened, water flows from the water inlet chamber 116 into the water outlet channel 115 through the water passage 1131. Since the cross-sectional area of ​​the first sealing hole 117 is smaller than that of the second sealing hole 118, the force exerted by the water pressure on the push-button valve core 12 through the first sealing part 122 is less than the force exerted by the water pressure on the push-button valve core 12 through the third sealing part 124. As a result, the water pressure provides a force along the pressing direction to the push-button valve core 12 as a whole, and the push-button valve core 12 opens automatically.

[0090] When the push-button valve core 12 is pushed to the closed position by the linkage conversion element 13, the second sealing part 123 blocks the water passage hole 1131. The water pressure in the water inlet chamber 116 provides force to the push-button valve core 12 through the second sealing part 123 and the third sealing part 124. Since the cross-sectional area of ​​the water passage hole 1131 is larger than the cross-sectional area of ​​the second sealing hole 118, the push-button valve core 12 is subjected to a force in the opposite direction of the pressing direction under the action of water pressure, and remains in the closed position, effectively preventing water leakage.

[0091] When the cross-sections of the first sealing hole 117, the second sealing hole 118, and the water passage hole 1131 are all circular, the diameter R1 of the first sealing hole 117, the diameter R2 of the second sealing hole 118, and the diameter R3 of the water passage hole 1131 satisfy the following condition: R1 < R2 < R3.

[0092] Furthermore, such as Figures 12 to 14As shown, in some embodiments, the valve body 11 is also provided with a plurality of buttons 16, each button 16 corresponding to a push-button valve core 12. One end of the push-button valve core 12 is engaged with the button 16. The valve body 11 is also provided with a plurality of positioning ribs 119 at the position corresponding to each button 16. The length direction of each positioning rib 119 is consistent with the pressing direction of the push-button valve core 12, and each positioning rib 119 is inserted into the button 16.

[0093] Guided by the positioning rib 119, the button 16 can slide stably in the pressing direction. When the button 16 is pressed, the corresponding push-button valve core 12 is also pressed down.

[0094] like Figure 4 and Figure 5 As shown, the end of the push-button valve core 12 is spherical. (As indicated...) Figure 13 and Figure 14 As shown, button 16 has a snap-fit ​​protrusion 161, and the spherical structure at the end of the push-button valve core 12 can be limited on button 16 by the snap-fit ​​protrusion 161. A limiting wall 162 is also provided on the side of button 16 facing the push-button valve core 12, and the limiting wall 162 surrounds the outside of each positioning rib 119. When button 16 is pressed, the positioning ribs 119 slide within the limiting wall 162.

[0095] Furthermore, such as Figure 15 and Figure 16 As shown, in some embodiments of this application, a water outlet device 20 is provided, including the switching valve 10 described in any of the above claims. When switching the water outlet mode, since both the swing member 14 and the elastic component 15 can adapt to the movement process of the linkage conversion member 13 by rotating or deforming themselves, the operation is smoother and the user experience is greatly improved.

[0096] like Figure 15 and Figure 16 As shown, in some embodiments, the water outlet device 20 further includes a body 21 and a cover 22. The body 21 and the cover 22 are snap-fitted together to form multiple water outlet chambers. The cover 22 has multiple sets of water outlet holes 221, which are connected to the multiple water outlet chambers one by one. The body 21 is mounted on the valve body 11, and the multiple water outlet chambers are connected to the multiple water outlet channels 115 one by one. Different water outlet modes are switched by different push-button valve cores 12.
