These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.
[0047] refer to Figures 1-13 As shown, an embodiment of the present invention provides a push-type diverter valve, comprising a valve body 1, a valve core 2 and a pressing shaft 3, wherein a valve cavity is formed in the valve body 1, and a socket communicating with the valve cavity, a water inlet 122, a first water outlet 127 and a second water outlet 128 are also formed on the valve body 1. The first end of the pressing shaft 3 is inserted into the valve cavity from the socket and movably connected to the valve body 1. The valve core 2 is arranged in the valve cavity and is driven by the pressing shaft 3 to switch between a first position and a second position along its own axis. When the valve core 2 is in the first position, water flows out of the first water outlet 127, and when the valve core 2 is in the second position, water flows out of the second water outlet 128. In order to maintain the stability of the valve core 2 in the first position and the second position, the push-type diverter valve further comprises a first elastic member 7 and a locking member 4, wherein the first elastic member 7 is used to keep the valve core 2 in the first position, and the locking member 4 is used to unidirectionally lock the valve core 2 in the second position. Specifically, the pressing shaft 3 is set to a hollow cylindrical structure, and a first guide groove 31, a second guide groove 32 and an avoidance groove 33 are set on its side wall, wherein the first guide groove 31 and the second guide groove 32 are arranged opposite to each other along the radial direction of the pressing shaft 3, and the locking member 4 is located in the pressing shaft 3 and is rotatably connected to the valve body 1 through a rotating shaft 5 that passes through the pressing shaft 3 radially along the pressing shaft 3 from the avoidance groove 33. When the pressing shaft 3 pushes the valve core 2 to move the valve core 2 from the first position to the second position, the locking member 4 can contact the side wall of the first guide groove 31 away from the valve core 2 and rotate, and lock in the second guide groove 32 when the pressing shaft 3 pushes the valve core 2 to the second position, thereby limiting the movement of the pressing shaft 3 in the direction away from the valve core 2, and thereby locking the valve core 2 in one direction in the second position. When the pressing shaft 3 is pressed again, the locking member 4 can continue to rotate under the push of the side wall of the first guide groove 31 until it disengages from the second guide groove 32, thereby releasing the restriction on the pressing shaft 3, and the valve core 2 returns to the first position from the second position under the action of the first elastic member 7.
[0048] The above-mentioned push-type diverter valve realizes the switching of the valve core 2 between the first position and the second position by pressing the pressing shaft 3, and a first guide groove 31 and a second guide groove 32 are provided on the pressing shaft 3, and a locking member 4 is provided on the valve body 1 and penetrates into the pressing shaft 3. As the pressing shaft 3 pushes the valve core 2 to move from the first position to the second position, the first guide groove 31 can drive the locking member 4 to rotate and be stuck in the second guide groove 32. With the cooperation of the first elastic member 7, the valve core 2 is kept in the second position. At this time, water flows out of the second water outlet 128. When the pressing shaft 3 is pressed again, the locking member 4 rotates and exits the second guide groove 32. The pressing shaft 3 moves away from the valve core 2 under the action of the first elastic member 7, and the valve core 2 returns to the first position. At this time, water flows out of the first water outlet 127. Obviously, with the cooperation of the first elastic member 7 and the locking member 4, the valve core 2 can be stably maintained in the first position or the second position, and it is not easy to leak from the other disconnected water outlet, and the reliability is high.
[0049] Specifically, refer to Figure 6 and Figure 8 As shown, the locking member 4 is an axisymmetric shape, with V-shaped grooves provided at both ends of the length of the locking member 4, and the notches of the two V-shaped grooves are oriented in opposite directions, that is, both ends of the length of the locking member 4 are configured as fishtail shapes. For ease of description, the locking member 4 includes a first V-shaped groove 41 and a second V-shaped groove 42. The first guide groove 31 and the second guide groove 32 overlap along the radial projection of the pressing shaft 3. The distance between the side of the second guide groove 32 away from the valve core 2 and the end of the pressing shaft 3 away from the valve core 2 is less than the distance between the side of the first guide groove 31 away from the valve core 2 and the end of the pressing shaft 3 away from the valve core 2. The width of the locking member 4 is greater than the distance between the first guide groove 31 and the second guide groove 32.
[0050] When the valve core 2 is in the first position, the locking member 4 is located at a position where the radial projections of the first guide groove 31 and the second guide groove 32 in the pressing shaft 3 coincide with each other, and the locking member 4 is in an upright state along the axial direction of the valve core 2, that is, the two V-shaped grooves on the locking member 4 are spaced apart along the axial direction of the pressing shaft 3. Since the width of the locking member 4 is greater than the distance between the first guide groove 31 and the second guide groove 32, the locking member 4 is always located in the first guide groove 31. When the pressing shaft 3 moves relative to the locking member 4, as the pressing shaft 3 moves As the valve core 2 moves in the direction of rotation, the sidewall of the first guide groove 31 on the side away from the valve core 2 contacts the sidewall of the first V-shaped groove 41 of the locking member 4. The locking member 4 is pushed and rotated by the pressing shaft 3, and the locking member 4 partially enters the second guide groove 32. When the valve core 2 is driven to the second position, the sidewall of the second guide groove 32 on the side close to the valve core 2 is confined within the second V-shaped groove 42 of the locking member 4, limiting the movement of the pressing shaft 3 in the direction away from the locking member 4. Therefore, the valve core 2 is unidirectionally locked in the second position. When the pressing shaft 3 is pressed again, the sidewall of the second guide groove 32 disengages from the second V-shaped groove 42 of the locking member 4. The sidewall of the first guide groove 31 on the side away from the valve core 2 contacts the locking member 4 and pushes the locking member 4 to continue rotating in the original direction until the locking member 4 disengages from the second guide groove 32 and returns to an upright state. At this point, the pressing shaft 3 is no longer restricted by the locking member 4, and the valve core 2 can be switched from the second position to the first position under the action of the first elastic member 7. It can be understood that the distance between the side of the second guide groove 32 away from the valve core 2 and the end of the pressing shaft 3 away from the valve core 2 is smaller than the distance between the side of the first guide groove 31 away from the valve core 2 and the end of the pressing shaft 3 away from the valve core 2. This is to prevent the side wall of the second guide groove 32 away from the valve core 2 from interfering with the rotation of the locking member 4.
[0051] refer to Figure 9 and Figure 10 As shown, the avoidance groove 33 passes through the end of the pressing shaft 3 close to the valve core 2 to reduce the difficulty of setting the locking member 4 in the pressing shaft 3. During assembly, the rotating shaft 5 passes through the avoidance groove 33 from the end of the pressing shaft 3 close to the valve core 2. Specifically, the rotating shaft 5 is fixed in the valve cavity through the fixing seat 6. In order to achieve axial limitation between the rotating shaft 5 and the locking member 4, the rotating shaft 5 includes a rotating shaft body 51 and a limiting portion 52, wherein one end of the rotating shaft body 51 is fixedly connected to the fixing seat 6, and the other end is bolted to the limiting portion 52. The limiting portion 52 is set to a T shape, and the outer diameter of the end of the limiting portion 52 connected to the rotating shaft body 51 is smaller than the outer diameter of the rotating shaft body 51. During assembly, the locking member 4 is sleeved on the limiting portion 52, and then the limiting portion 52 is connected to the rotating shaft body 51, so that the locking member 4 is axially limited to the rotating shaft 5.
[0052] Specifically, refer to Figure 2 and Figure 3As shown, the valve chamber includes an inlet channel 121, a first water outlet channel 124 and a second water outlet channel 131. The inlet channel 121 is connected to the external water supply pipeline through the water inlet 122. The first water outlet channel 124 is connected to the first water outlet 127 and the inlet channel 121. The second water outlet channel 131 is connected to the second water outlet 128 and the inlet channel 121. The inlet of the first water outlet channel 124 and the inlet of the second water outlet channel 131 are arranged at intervals along the axial direction of the valve core 2.
[0053] The valve core 2 includes a valve stem 21 and a sealing head 22. The sealing head 22 is arranged at the end of the valve stem 21 away from the pressing shaft 3. When the valve core 2 moves axially, the sealing head 22 can block the inlet of the first water outlet channel 124 to allow water to flow through the second water outlet channel 131 and flow out from the second water outlet 128, or block the inlet of the second water outlet channel 131 to allow water to flow through the first water outlet channel 124 and flow out from the first water outlet 127.
[0054] In one embodiment, continue to refer to Figure 2 and Figure 4As shown, the valve body 1 includes an outer shell 11, an inner shell 12 and a sleeve 13. The shape of the outer shell 11 can be set according to actual needs. For example, in order to improve the aesthetics, the outer shell 11 is set to be approximately cylindrical, and the first water outlet 127 and the second water outlet 128 are arranged on the outer shell 11 at axial intervals along the valve core 2. The first end of the inner shell 12 is inserted into the outer shell 11 and fixedly connected to the outer shell 11, for example, the inner shell 12 is snap-fitted to the outer shell 11. The second end of the inner shell 12 forms the above-mentioned water inlet 122. A bushing 13 and a separation sleeve 15 are provided in the inner shell 12 along the axial direction of the valve core 2. The separation sleeve 15 is provided on the side of the bushing 13 facing the water inlet, and the end of the separation sleeve 15 facing the bushing 13 is open, and the end facing the water inlet 122 is closed. A water inlet flow channel 121 is formed between the separation sleeve 15 and the inner shell 12, and a first water outlet flow channel 124 is formed in the separation sleeve 15. The first water outlet flow channel 124 is connected to the water inlet flow channel 121 through the opening of the separation sleeve 15, that is, the separation sleeve 15 is closed. The opening is the inlet of the first water outlet channel 124. The bushing 13 opens at one end facing the separating sleeve 15. The first water outlet channel 124 is formed within the bushing 13. A first communication port 132 is formed on the sidewall of the bushing 13. A second communication port 125 is provided in the inner shell 12 at a position corresponding to the first communication port 132. The second communication port 125 is connected to the first water outlet 127 of the outer shell 11. The valve core 2 is movably inserted into the bushing 13 and can selectively block the opening at the end of the bushing 13 facing the separating sleeve 15 or the opening at the end of the separating sleeve 15 facing the bushing 13. Specifically, based on the arrangement of the separating sleeve 15, the first elastic member 7 is a compression spring, which is disposed within the separating sleeve 15 and connected to the valve core 2. More specifically, the separating sleeve 15 is integrally formed with the inner shell 12. The separating sleeve 15 and the inner shell 12 share a sidewall, through which a third communication port is formed that connects to the first water outlet 127.
[0055] By disposing the bushing 13 and the separation sleeve 15 , the water inlet channel 121 , the first water outlet channel 124 and the second water outlet channel 131 can all be disposed in the approximately cylindrical housing 11 , resulting in a simple and beautiful shape.
[0056] In other embodiments, the housing 11 may be configured as a three-way shape, that is, the water inlet channel 121 , the first water outlet channel 124 and the second water outlet channel 131 are independently configured, which will not be further described here.
[0057] When the valve core 2 is in the first position, the sealing head 22 blocks the end of the sleeve 13 close to the separating sleeve 15, that is, blocks the inlet of the second water outlet channel 131, and the water flows from the first water outlet channel 124 to the first water outlet 127; when the valve core 2 is in the second position, the sealing head 22 blocks the opening of the separating sleeve 15, that is, blocks the inlet of the first water outlet channel 124, and the water flows from the second water outlet channel 131 through the first connecting port 132 and the second connecting port 125 to the second water outlet 128.
[0058] More specifically, the sealing head 22 is configured as a tapered shape with a radius gradually decreasing from one end near the pressing shaft 3 to the other end, thereby reducing the difficulty of inserting the valve core 2 into the second water outlet channel 131. Furthermore, to prevent water from escaping through the gap between the bushing 13 and the valve core 2 when the valve core 2 is in the second position, a sealing ring 20 is also mounted on the valve stem 21. The sealing ring 20 is located on the side of the first communication port 132 away from the separation sleeve 15 to prevent water from escaping from the end of the bushing 13 away from the separation sleeve 15. Exemplarily, the sealing ring 20 is a V-shaped sealing ring to reduce friction when the valve core 2 moves relative to the bushing 13, thereby extending the service life of the sealing ring 20.
[0059] In one embodiment, a first abutment portion (not shown in the figure) is further provided in the bushing 13, and the first abutment portion extends along the axial direction of the valve core 2. The valve stem 21 is passed through the first abutment portion and the sealing head 22 is located at one end of the first abutment portion close to the first water outlet channel 124. Under the action of the first elastic member 7, the sealing head 22 of the valve core 2 in the first position abuts against the first abutment portion, thereby limiting the valve core 2 from continuing to move in a direction away from the first water outlet channel 124.
[0060] refer to Figure 3 、 Figure 11 and Figure 12As shown, in order to reduce the difficulty of assembling the bushing 13, a first limiting step 126 is provided on the inner circumferential wall of the inner shell 12, and a first limiting protrusion 133 is provided on the outer circumferential wall of the bushing 13. The first limiting step 126 abuts against the first limiting protrusion 133, thereby limiting the depth of insertion of the bushing 13 into the inner shell 12. At the same time, the valve body 1 also includes a sleeve 14, which is sleeved on the pressing shaft 3 and has a second limiting protrusion 141 provided on the outer circumferential wall of the sleeve 14. A limiting groove 123 is provided at the end of the inner shell 12 away from the water inlet 122. The second limiting protrusion 141 is limited in the limiting groove 123 by rotation, thereby achieving axial limitation of the sleeve 14 relative to the inner shell 12. The sleeve 14 abuts against the bushing 13, thereby achieving fixation of the sleeve 13 relative to the inner shell 12. It is worth emphasizing that the inner diameter of the sleeve 14 is smaller than the inner diameter of the bushing 13, and the pressing shaft 3 also includes an axially connected large diameter section and a small diameter section, wherein the large diameter section is located in the bushing 13, and the small diameter section is arranged at the end of the large diameter section away from the valve core 2. A third limiting step 16 is formed between the sleeve 14 and the bushing 13. When the valve core 2 is in the first position, the large diameter section abuts against the third limiting step 16, thereby further limiting the stroke of the pressing shaft 3 moving toward the valve body 1, and preventing the pressing shaft 3 from separating from the valve body 1.
[0061] When assembling the pressing shaft 3 , first insert the large diameter section of the pressing shaft 3 into the bushing 13 , then abut the sleeve 14 against the bushing 13 and limit the rotation to the inner shell 12 to prevent the pressing shaft 3 from separating from the bushing 13 .
[0062] Specifically, to reduce the difficulty of inserting the second limiting protrusion 141 into the limiting groove 123, the thickness of the second limiting protrusion 141 gradually increases from one end to the other along the circumference of the sleeve 14. Thickness refers to the axial dimension of the second limiting protrusion 141 along the valve core 2. A limiting block 142 is provided at the thicker end of the second limiting protrusion 141 to prevent further rotation of the second limiting protrusion 141. More specifically, two second limiting protrusions 141 and two limiting blocks 142 are centrally symmetrically arranged on the sleeve 14 to enhance axial stability between the sleeve 14 and the valve body 1.
[0063] Based on the arrangement of the bushing 13, the fixing seat 6 is fixed by the bushing 13. Specifically, referring to Figure 13 As shown, a second abutting portion 134 is protruded from one end of the bushing 13 near the shaft sleeve 14. The second abutting portion 134 abuts the shaft sleeve 14, and an embedding groove 135 is formed on the inner side of the second abutting portion 134. The embedding groove 135 extends toward one end of the shaft sleeve 14 to the end surface of the second abutting portion 134. The fixing sleeve is inserted into the embedding groove 135 along the axial direction of the valve core 2 and is fixed under the restraint of the shaft sleeve 14, thereby reducing the difficulty of later disassembly and assembly of the fixing seat 6. For example, the cross-section of the fixing seat 6 is set to be an arc shape that adapts to the shape of the bushing 13.
[0064] refer to Figure 2 As shown, in one embodiment, to enhance the user experience, a push button 30 is provided at the end of the push shaft 3 away from the valve core 2. The orthographic projection area of the push button 30 toward the push shaft 3 is larger than the radial cross-sectional area of the push shaft 3. Specifically, the push button 30 includes a connecting sleeve, into which the second end of the push shaft 3 is inserted and engaged.
[0065] To provide a better feel when pressing the push button 30, the push-type diverter valve further includes a second elastic member 10, which keeps the push button 30 moving away from the valve body 1. To prevent the push button 30 from separating from the valve body 1 under the second elastic member 10, the push button 30 further includes a pressing portion. The second elastic member 10 connects the pressing portion and the valve body 1. The pressing portion is connected to the end of the connecting sleeve away from the valve core 2 and is engaged with the valve body 1.
