[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. In addition, it should be noted that for the sake of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all the structures.

[0044] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0045] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0046] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0047] As shown in the reference Figures 1 - 13 In the embodiment of the present invention, a push - type flow - dividing valve is proposed, which includes a valve body 1, a valve core 2, and a push - button shaft 3. A valve cavity is formed in the valve body 1. An insertion port, a water inlet 122, a first water outlet 127, and a second water outlet 128 communicating with the valve cavity are further formed on the valve body 1. The first end of the push - button shaft 3 is inserted into the valve cavity from the insertion port and is movably connected to the valve body 1. The valve core 2 is arranged in the valve cavity and is driven by the push - button shaft 3 to switch between a first position and a second position along its own axial direction. When the valve core 2 is in the first position, the first water outlet 127 discharges water. When the valve core 2 is in the second position, the second water outlet 128 discharges water. In order to maintain the stability of the valve core 2 in the first position and the second position, the push - type flow - dividing valve further includes a first elastic member 7 and a locking member 4. The first elastic member 7 is used to keep the valve core 2 in a tendency to be in the first position, and the locking member 4 is used to unidirectionally lock the valve core 2 in the second position. Specifically, the push - button shaft 3 is arranged as a hollow cylindrical structure, and a first guiding groove 31, a second guiding groove 32, and an avoidance groove 33 are arranged on its side wall. The first guiding groove 31 and the second guiding groove 32 are oppositely arranged along the radial direction of the push - button shaft 3. The locking member 4 is located inside the push - button shaft 3 and is rotatably connected to the valve body 1 through a rotating shaft 5 that passes through the push - button shaft 3 radially from the avoidance groove 33. When the push - button shaft 3 pushes the valve core 2 to move from the first position to the second position, the locking member 4 can contact the side wall of the first guiding groove 31 away from the valve core 2 and thus rotate, and is locked in the second guiding groove 32 when the push - button shaft 3 pushes the valve core 2 to the second position, restricting the push - button shaft 3 from moving in the direction away from the valve core 2, thereby unidirectionally locking the valve core 2 in the second position. When the push - button shaft 3 is pressed again, the locking member 4 can continue to rotate under the push of the groove side wall of the first guiding groove 31 to disengage from the second guiding groove 32, thereby releasing the restriction on the push - button shaft 3, and the valve core 2 returns from the second position to the first position under the action of the first elastic member 7.

[0048] The above-mentioned pressing type flow dividing valve realizes the switching of the valve core 2 between the first position and the second position by pressing the pressing shaft 3. A first guiding groove 31 and a second guiding groove 32 are arranged on the pressing shaft 3, and a locking member 4 penetrating into the pressing shaft 3 is arranged on the valve body 1. As the pressing shaft 3 pushes the valve core 2 to move from the first position to the second position, the first guiding groove 31 can drive the locking member 4 to rotate and be stuck in the second guiding groove 32, and with the cooperation of the first elastic member 7, the valve core 2 is kept in the second position. At this time, the second water outlet 128 discharges water; when the pressing shaft 3 is pressed again, the locking member 4 rotates and exits the second guiding groove 32, and 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, the first water outlet 127 discharges water. Obviously, with the cooperation of the first elastic member 7 and the locking member 4, the valve core 2 can be stably kept in the first position or the second position, is not easy to leak water from the other water outlet that has been disconnected, and has high reliability.

[0049] Specifically, referring to Figure 6 and Figure 8 as shown, the locking member 4 is an axisymmetric figure. V-shaped grooves are arranged at both ends of the length of the locking member 4, and the notch directions of the two V-shaped grooves are opposite, that is, both ends of the length of the locking member 4 are arranged in a fish-tail shape. For the convenience of description, the locking member 4 includes a first V-shaped groove 41 and a second V-shaped groove 42. The radial projections of the first guiding groove 31 and the second guiding groove 32 on the pressing shaft 3 overlap, and the distance between the side of the second guiding groove 32 away from the valve core 2 and the end of the side of the pressing shaft 3 away from the valve core 2 is less than the distance between the side of the first guiding groove 31 away from the valve core 2 and the end of the side 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 guiding groove 31 and the second guiding groove 32.

[0050] When the valve core 2 is in the first position, the locking member 4 is located at the position in the pressing shaft 3 where the radial projections of the first guiding groove 31 and the second guiding groove 32 coincide. 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 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 guiding groove 31 and the second guiding groove 32, a part of the locking member 4 is always located in the first guiding groove 31. When the pressing shaft 3 moves relative to the locking member 4, as the pressing shaft 3 moves towards the valve core 2, the groove side wall on the side of the first guiding groove 31 away from the valve core 2 contacts the groove side wall of the first V-shaped groove 41 of the locking member 4, and the locking member 4 is pushed by the pressing shaft 3 to rotate. A part of the locking member 4 enters the second guiding groove 32. When the valve core 2 is driven to the second position, the groove side wall on the side of the second guiding groove 32 close to the valve core 2 is limited in the second V-shaped groove 42 of the locking member 4, restricting the pressing shaft 3 from moving 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 groove side wall of the second guiding groove 32 disengages from the second V-shaped groove 42 of the locking member 4, and the groove side wall on the side of the first guiding groove 31 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 guiding groove 32 and returns to the upright state again. At this time, 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 guiding 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 guiding groove 31 away from the valve core 2 and the end of the pressing shaft 3 away from the valve core 2, in order to prevent the groove side wall on the side of the second guiding groove 32 away from the valve core 2 from interfering with the rotation of the locking member 4.

[0051] Reference Figure 9 and Figure 10 As shown, the avoidance groove 33 penetrates through one end of the pressing shaft 3 close to the valve core 2 to reduce the difficulty of arranging the locking member 4 in the pressing shaft 3. During assembly, the rotating shaft 5 penetrates into the avoidance groove 33 from one 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 the axial limit 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. 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 arranged in 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, thereby axially limiting the locking member 4 on the rotating shaft 5.

[0052] Specifically, reference Figure 2 and Figure 3As shown, the valve cavity includes an inlet water flow path 121, a first outlet water flow path 124, and a second outlet water flow path 131. The inlet water flow path 121 is communicated with an external water supply pipeline through a water inlet 122. The first outlet water flow path 124 is communicated with a first water outlet 127 and the inlet water flow path 121. The second outlet water flow path 131 is communicated with a second water outlet 128 and the inlet water flow path 121. And the inlets of the first outlet water flow path 124 and the second outlet water flow path 131 are arranged at intervals along the axial direction of the valve element 2.

[0053] The valve element 2 includes a valve stem 21 and a sealing head 22. The sealing head 22 is arranged at one end of the valve stem 21 away from the pressing shaft 3. When the valve element 2 moves axially, the sealing head 22 can block the inlet of the first outlet water flow path 124 so that water flows out from the second water outlet 128 through the second outlet water flow path 131, or block the inlet of the second outlet water flow path 131 so that water flows out from the first water outlet 127 through the first outlet water flow path 124.

[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 bushing 13. The shape of the outer shell 11 can be set according to actual requirements. For example, in order to improve the aesthetics, the outer shell 11 is set to be approximately cylindrical. The first water outlet 127 and the second water outlet 128 are arranged on the outer shell 11 at intervals along the axial direction of 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 with the outer shell 11. The second end of the inner shell 12 forms the above-mentioned water inlet 122. A bushing 13 and a partition sleeve 15 are arranged in the inner shell 12 at intervals along the axial direction of the valve core 2. The partition sleeve 15 is arranged on the side of the bushing 13 facing the water inlet, and one end of the partition 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 partition sleeve 15 and the inner shell 12. A first water outlet flow channel 124 is formed in the partition sleeve 15. The first water outlet flow channel 124 communicates with the water inlet flow channel 121 through the opening of the partition sleeve 15, that is, the opening of the partition sleeve 15 is the inlet of the first water outlet flow channel 124. One end of the bushing 13 facing the partition sleeve 15 is open, and the first water outlet flow channel 124 is formed in the bushing 13. A first communication port 132 is formed on the side wall of the bushing 13. A second communication port 125 is arranged at the position of the inner shell 12 corresponding to the first communication port 132. The second communication port 125 communicates with the first water outlet 127 of the outer shell 11. The valve core 2 movably penetrates through the bushing 13 and can selectively block the opening of one end of the bushing 13 facing the partition sleeve 15 or the opening of one end of the partition sleeve 15 facing the bushing 13. Specifically, based on the setting of the partition sleeve 15, the first elastic member 7 is a compression spring, and the compression spring is arranged in the partition sleeve 15 and connected to the valve core 2. More specifically, the partition sleeve 15 and the inner shell 12 are integrally formed, the partition sleeve 15 and the inner shell 12 have a common side wall, and a third communication port communicating with the first water outlet 127 is formed through the side wall.

[0055] Through the settings of the bushing 13 and the partition sleeve 15, the water inlet flow channel 121, the first water outlet flow channel 124 and the second water outlet flow channel 131 can be arranged in the approximately cylindrical outer shell 11, with a simple and beautiful shape.

[0056] In other embodiments, the outer shell 11 can also be set to be a tee shape, that is, the water inlet flow channel 121, the first water outlet flow channel 124 and the second water outlet flow channel 131 are independently arranged, which will not be elaborated here.

[0057] When the valve core 2 is in the first position, the sealing head 22 plugs one end of the bushing 13 close to the partition sleeve 15, that is, plugs 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 plugs the opening of the partition sleeve 15, that is, plugs the inlet of the first water outlet channel 124, and the water flows from the second water outlet channel 131 through the first communication port 132 and the second communication port 125 to the second water outlet 128.

[0058] More specifically, the sealing head 22 is arranged as a cone with a gradually decreasing radius from one end close to the pressing shaft 3 to the other end, so as to reduce the difficulty of inserting the valve core 2 into the second water outlet channel 131. At the same time, in order to prevent water from flowing out from 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 sleeved on the valve stem 21. The sealing ring 20 is located on the side of the first communication port 132 away from the partition sleeve 15 to prevent water from flowing out from one end of the bushing 13 away from the partition sleeve 15. Exemplarily, the sealing ring 20 adopts a V-shaped sealing ring to reduce the friction force when the valve core 2 moves relative to the bushing 13 and extend the service life of the sealing ring 20.

[0059] In an embodiment, a first abutting portion (not shown in the figure) is further arranged in the bushing 13. The first abutting portion extends along the axial direction of the valve core 2. The valve stem 21 passes through the first abutting portion and the sealing head 22 is located at one end of the first abutting 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 abutting portion, restricting the valve core 2 from continuing to move in the direction away from the first water outlet channel 124.

[0060] Reference Figure 3 、 Figure 11 and Figure 12As shown, in order to reduce the assembly difficulty of the bushing 13, a first limiting step 126 is provided on the inner peripheral wall of the inner shell 12, and a first limiting protrusion 133 is provided on the outer peripheral 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 further includes a shaft sleeve 14 sleeved on the pressing shaft 3. A second limiting protrusion 141 is provided on the outer peripheral wall of the shaft sleeve 14, and a limiting groove body 123 is provided at one end of the inner shell 12 away from the water inlet 122. The second limiting protrusion 141 is rotationally limited within the limiting groove body 123 to achieve axial limiting of the shaft sleeve 14 relative to the inner shell 12. Since the shaft sleeve 14 abuts against the bushing 13, the bushing 13 is fixed relative to the inner shell 12. It should be emphasized that the inner diameter of the shaft sleeve 14 is smaller than the inner diameter of the bushing 13, and the pressing shaft 3 also includes a large-diameter section and a small-diameter section connected axially. The large-diameter section is located within the bushing 13, and the small-diameter section is provided at one end of the large-diameter section away from the valve core 2. A third limiting step 16 is formed between the shaft 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 moving stroke of the pressing shaft 3 towards the valve body 1 and preventing the pressing shaft 3 from disengaging 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 shaft sleeve 14 against the bushing 13 and rotationally limit it to the inner shell 12, which can prevent the pressing shaft 3 from disengaging from the bushing 13.

[0062] Specifically, in order to reduce the difficulty of inserting the second limiting protrusion 141 into the limiting groove body 123, the thickness of the second limiting protrusion 141 gradually increases along the circumferential direction of the shaft sleeve 14 from one end to the other end. The thickness refers to the dimension of the second limiting protrusion 141 along the axial direction of the valve core 2. A limiting block 142 is provided at the end with a thicker thickness of the second limiting protrusion 141 to prevent the second limiting protrusion 141 from continuing to rotate. More specifically, two second limiting protrusions 141 and limiting blocks 142 are symmetrically arranged about the center on the shaft sleeve 14 to improve the axial stability between the shaft sleeve 14 and the valve body 1.

[0063] Based on the setting of the bushing 13, the fixing seat 6 is fixed through the bushing 13. Specifically, referring to Figure 13 As shown, a second abutting portion 134 protrudes from one end of the bushing 13 close to the shaft sleeve 14. The second abutting portion 134 abuts against the shaft sleeve 14, and an embedding groove 135 is formed inside the second abutting portion 134. One end of the embedding groove 135 facing the shaft sleeve 14 extends to the end face of the second abutting portion 134. The fixing sleeve is axially inserted into the embedding groove 135 and is fixed under the limitation of the shaft sleeve 14, reducing the later disassembly and assembly difficulty of the fixing seat 6. Exemplarily, the cross-section of the fixing seat 6 is set to be circular arc-shaped to match the shape of the bushing 13.

[0064] Referring toFigure 2 As shown, in one embodiment, in order to improve the user experience, a pressing key 30 is provided at one end of the pressing shaft 3 away from the valve core 2, and the orthographic projection area of the pressing key 30 in the direction of the pressing shaft 3 is larger than the radial cross-sectional area of the pressing shaft 3. Specifically, the pressing key 30 includes a connecting sleeve, and the second end of the pressing shaft 3 is inserted into the connecting sleeve and is in snap-fit connection with the connecting sleeve.

[0065] In order to have a better feel when pressing the pressing key 30, the pressing type flow dividing valve further includes a second elastic member 10, and the second elastic member 10 causes the pressing key 30 to maintain a tendency to move away from the valve body 1. In order to prevent the pressing key 30 from detaching from the valve body 1 under the action of the second elastic member 10, the pressing key 30 further includes a pressing portion, the second elastic member 10 is connected between the pressing portion and the valve body 1, the pressing portion is connected to one end of the connecting sleeve away from the valve core 2, and the pressing portion is in snap-fit connection with the valve body 1.

[0066] In an embodiment of the present invention, a water outlet device is proposed, which includes the above-mentioned pressing type flow dividing valve, a first water outlet head 8 and a second water outlet head 9. The first water outlet head 8 communicates with the first water outlet 127, and the second water outlet head 9 communicates with the second water outlet 128. Exemplarily, in order to simplify the water outlet device, both the first water outlet head 8 and the second water outlet head 9 are embedded in the valve body 1. The specific structures of the first water outlet head 8 and the second water outlet head 9 are selected according to actual needs and are not specifically limited here. For example, a plurality of water outlet holes are provided on the first water outlet head 8, and only one water outlet hole is provided on the second water outlet head 9.

[0067] It can be understood that since the water outlet device includes the pressing type flow dividing valve, it has the advantages of the above-mentioned pressing type flow dividing valve, and will not be repeated here.

[0068] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the embodiments of the present invention.
