[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] refer to Figures 1 to 3 , an embodiment of the present application provides a water valve for controlling the flow and blocking of water.

[0041] Specifically, the water valve of the embodiment of the present application includes a valve body 100 and a valve assembly. The valve body 100 includes a water inlet 111, a water outlet 112 and a main body 113. The water inlet 111 and the water outlet 112 are respectively located in the radial direction ( Figure 1 On both sides of the housing (shown in the X direction), the water inlet 111 is used to connect to a water source (not shown in the figure), and the water outlet 112 is used to connect to a water spraying member (not shown in the figure, such as a water spraying pipe or a spray head).

[0042] like Figure 3 As shown, the water inlet portion 111 includes a water inlet channel 140 , the water outlet portion 112 includes a water outlet channel 150 , and the main body 113 is provided with a water inlet connecting channel 141 and a water outlet connecting channel 151 , wherein the water inlet connecting channel 141 connects the water inlet channel 140 , and the water outlet connecting channel 151 connects the water outlet channel 150 .

[0043] The valve assembly is used to control the connectivity between the water inlet channel 140 and the water outlet channel 150, that is, to control the connectivity between the water inlet connecting channel 141 and the water outlet connecting channel 151, so as to realize that the water in the water inlet channel 140 flows to the water inlet connecting channel 141, and then flows from the water inlet connecting channel 141 to the water outlet connecting channel 151, and the water in the water outlet connecting channel 151 flows to the water outlet channel 150 and is finally sprayed out, and when spraying water is not required, the water in the water inlet channel 140 is prevented from flowing into the water outlet channel 150 along the flow direction of the above-mentioned water flow.

[0044] Specifically, refer to Figure 3 and Figure 4 The valve body 100 includes a water inlet chamber 130, a water outlet chamber 117 and a valve channel 114. The water inlet chamber 130 and the water inlet channel 140 are connected through a water inlet connecting channel 141. The water inlet chamber 130 stores water from the water inlet channel 140. The water outlet chamber 117 is located in the valve channel 114. The water inlet chamber 130 and the water outlet chamber 117 are adjacent to each other, and a pressure-bearing portion 110 is provided between the water inlet chamber 130 and the water outlet chamber 117.

[0045] The pressure-bearing part 110 includes a water inlet 115, one end of which is connected to the water inlet chamber 130 and the other end of which is connected to the water outlet chamber 117; the water outlet chamber 117 includes a water outlet 116, and the water outlet 116 is connected to the water outlet channel 150 through the water outlet connecting channel 151. The water inlet 115 is located at the lower end of the valve channel 114, and the water inlet chamber 130 is located below the valve channel 114. Whether the water inlet 115 is closed or not determines whether the water inlet chamber 130 is connected to the water outlet chamber 117, that is, whether the water inlet connecting channel 141 is connected to the water outlet connecting channel 151, that is, whether the water inlet channel 140 is connected to the water outlet channel 150.

[0046] like Figure 4 As shown, the pressure-bearing portion 110 is in a ring shape, and the water inlet 115 is located in a space surrounded by the inner wall of the pressure-bearing portion 110. For example, along the height direction of the main body 113 (that is, the axial direction of the valve stem described later, Figure 4 The inner diameter of the pressure-bearing portion 110 increases gradually from top to bottom. That is, the size (ie, inner diameter) of the water inlet 115 decreases gradually from the end connected to the water inlet cavity 130 to the end connected to the water outlet cavity 117.

[0047] like Figures 2 to 4 As shown, the valve assembly includes a valve stem 200, a pressing member 300 and an elastic member 400. The valve stem 200 is axially ( Figure 3 The valve stem 200 is inserted into the valve channel 114 (as shown in the Z direction), and the valve stem 200 includes a first end 201 and a second end 202. The first end 201 includes a sealing portion 210, and the sealing portion 210 is located in the water inlet cavity 130. The valve stem 200 is connected to the valve body 100 in a manner that it can move axially relative to the valve channel 114.

[0048] Specifically, the valve stem 200 moves, and the sealing portion 210 moves accordingly in the water inlet chamber 130 , thereby adjusting the relative position relationship of the sealing portion 210 with respect to the water inlet 115 of the pressure-bearing portion 110 to achieve blocking and opening of the water inlet 115 .

[0049] Furthermore, the radial dimension of the sealing portion 210 is greater than the radial dimension of the valve channel 114, and the radial dimension of the sealing portion 210 is greater than the minimum inner diameter of the water inlet 115 and smaller than the maximum inner diameter of the water inlet 115, thereby facilitating the sealing portion 210 to seal the pressure-bearing portion 110, that is, the sealing portion 210 abuts against the pressure-bearing portion 110, thereby forming a blockage for the water inlet 115.

[0050] It is easy to understand that when the water inlet chamber 130 is in a state of continuous water, the sealing portion 210 will be tightly attached to the pressure-bearing portion 110 under the action of water pressure, thereby blocking the water inlet 115 to separate the water outlet chamber 117 and the water inlet chamber 130.

[0051] The pressing member 300 is connected to the second end 202 of the valve stem 200, and is arranged along the axial direction ( Figure 3 The upper end of the elastic member 400 abuts against the pressing member 300, and the lower end of the elastic member 400 abuts against the valve body 100, so that an external force is applied to the pressing member 300 to push the valve stem 200, so that the sealing portion 210 of the valve stem 200 moves toward the pressure-bearing portion 110, or the external force applied to the pressing member 300 is canceled, and the elastic member 400 drives the valve stem 200 to move upward to disengage from the pressure-bearing portion 110.

[0052] Specifically, refer to Figures 2 to 5 , applying an external force (e.g. Figure 5 As shown in F1), the elastic member 400 is compressed, the pressing member 300 drives the valve stem 200 to move downward in the axial direction, the sealing portion 210 also separates from the pressure-bearing portion 110, the water inlet 115 is opened, the water outlet chamber 117 is connected to the water inlet chamber 130, and the water valve is in an open state. At this time, water flows, as shown in FIG. Figure 5 As shown in the direction of the middle arrow A, water from the water inlet channel 140 can flow through the water inlet connecting channel 141, and then enter the water inlet chamber 130. The water in the water inlet chamber 130 flows into the water outlet chamber 117 from the water inlet 115, and then flows from the water outlet 116 through the water outlet connecting channel 151, and flows to the water outlet channel 150, and finally flows out from the water outlet channel 150.

[0053] like Figure 3 and Figure 5 As shown, the valve stem 200 includes a stopper 230, the stopper 230 is located in the valve channel 114, and the stopper 230 and the water inlet 115 are axially aligned with the valve stem 200 ( Figure 5When the water valve is in the open state, the water in the water inlet chamber 130 flows into the water outlet chamber 117 from the water inlet 115, and the water flows along the axial direction of the valve stem 200 to impact the stopper 230, thereby forming an axial upward pressure on the valve stem 200. After the external force on the pressing member 300 is removed, the valve stem 200 will tend to move upward under the axial upward pressure of the water flow.

[0054] Specifically, Figure 3 and Figure 4 As shown, the external force on the pressing member 300 is removed, the elastic member 400 stretches, and the elastic force and the water pressure of the water flow on the valve stem 200 in the axial direction upward (for example Figure 4 F2) shown in FIG. 2 drives the valve stem 200 to move upward, and the sealing portion 210 of the valve stem 200 abuts against the pressure-bearing portion 110, thereby blocking the water inlet 115, and the water inlet chamber 130 and the water outlet chamber 117 are blocked. The water valve is in a closed state, and the water flow between the water inlet chamber 130 and the water outlet chamber 117 is blocked. Figure 4 Exemplarily, the sealing portion 210 serves as a blocking portion between the water inlet cavity 130 and the water outlet cavity 117 . When the water valve is closed, the sealing portion 210 blocks the water inlet 115 , thereby blocking the water inlet channel 140 and the water outlet channel 150 .

[0055] Using the above technical solution, refer to Figures 3 to 5 The water inlet chamber 130 is connected to the water inlet channel 140 , and the water outlet chamber 117 is connected to the water outlet channel 150 . Whether the water inlet chamber 130 and the water outlet chamber 117 are connected determines whether the water inlet channel 140 and the water outlet channel 150 are connected.

[0056] Specifically, the valve stem 200 is axially ( Figure 5 The valve stem 200 is inserted into the valve channel 114, and the sealing portion 210 of the valve stem 200 is located in the water inlet cavity 130, then an external force (such as Figure 5 As shown in F1 in the figure, the elastic member 400 is compressed, the pressing member 300 drives the valve stem 200 to move downward, and the sealing portion 210 moves accordingly. The sealing portion 210 moves downward along the axial direction to separate from the pressure-bearing portion 110, and the water inlet 115 is in an open state, which connects the water inlet chamber 130 and the water outlet chamber 117, and the water inlet channel 140 and the water outlet channel 150 are connected, as shown in FIG. Figure 5 As shown in the direction of the middle arrow A, water from the water inlet channel 140 can flow through the water inlet connecting channel 141, and then enter the water inlet chamber 130. The water in the water inlet chamber 130 flows into the water outlet chamber 117 from the water inlet 115, and then flows from the water outlet 116 to the water outlet connecting channel 151. The water in the water outlet connecting channel 151 flows to the water outlet channel 150, and finally flows out from the water outlet channel 150, thereby meeting people's entertainment or other needs.

[0057] Correspondingly, the external force applied to the pressing member 300 in the axial direction of the valve stem 200 is canceled, and the elastic member 400 is extended. At this time, the pressing member 300 is subjected to the elastic force in the axial direction of the valve stem 200 and the pressure of the water flow on the valve stem 200 in the axial direction (such as Figure 4 The sealing portion 210 moves upward along the axial direction to reach the top of the water inlet chamber 130, and the top of the water inlet chamber 130 is also the bottom of the valve channel 114. The sealing portion 210 abuts against the pressure-bearing portion 110, so that the sealing portion 210 blocks the water inlet 115, thereby realizing the closed state of the water valve, that is, the water inlet chamber 130 and the water outlet chamber 117 are not connected, and the water inlet channel 140 and the water outlet channel 150 are not connected. The water from the water inlet channel 140 is blocked outside the water outlet chamber 117 and cannot flow out from the water outlet channel 150, thereby meeting people's needs for blocking water.

[0058] In summary, the embodiment of the present application realizes the circulation and blocking of water flow by the up and down movement of the valve stem 200, and its structure is simple, easy to install, and low in cost.

[0059] refer to Figures 3 to 6 The sealing portion 210 includes a sleeve 211 and an extended end 212. The extended end 212 extends out of the valve channel 114 and is located in the water inlet chamber 130. The sleeve 211 covers the extended end 212 of the valve stem 200. When the water valve is in the closed state, the sleeve 211 abuts against the pressure-bearing portion 110, thereby forming a seal for the water inlet 115.

[0060] When the water valve is in the open state, the sleeve 211 is separated from the pressure-bearing portion 110, and the sleeve 211 and the water inlet 115 are axially aligned with the valve stem 200 ( Figure 5 That is, the water inlet 115 is in an open state, which connects the water inlet cavity 130 and the water outlet cavity 117, and the water from the water inlet channel 140 can enter the water inlet cavity 130 through the water inlet connecting channel 141, and the water in the water inlet cavity 130 flows to the water inlet 115, and then flows into the water outlet cavity 117 from the water inlet 115, and then flows from the water outlet 116 to the water outlet connecting channel 151, and then flows from the water outlet connecting channel 151 to the water outlet channel 150, and finally flows out from the water outlet channel 150.

[0061] In this embodiment, the sealing portion 210 and the pressure-bearing portion 110 abut against each other, thereby forming a seal of the water inlet 115 by the sealing portion 210 . However, those skilled in the art will appreciate that in other embodiments, the water inlet 115 may be sealed by other means.

[0062] Furthermore, the outer diameter of the protruding end 212 is larger than the minimum inner diameter of the water inlet 115 , so that the water inlet 115 can be blocked by the sleeve 211 sleeved on the protruding end 212 , thereby achieving a better sealing effect.

[0063] The sleeve 211 is sleeved on the extended end 212 of the valve stem 200, so that it can be more closely abutted against the pressure-bearing part 110, thereby improving the sealing performance and preventing the water in the water inlet chamber 130 from leaking into the water outlet chamber 117 when the water outlet channel 150 is not required to discharge water.

[0064] Specifically, refer to Figures 3 to 6 The valve stem 200 includes a first rod portion 220, and an annular groove 213 is provided between the first rod portion 220 and the protruding end 212. The sleeve 211 is a soft plastic product with elasticity. A hole is opened at its upper end to allow the protruding end 212 to extend into the interior of the sleeve 211. The opening of the sleeve 211 is snapped into the annular groove 213, thereby achieving the reliability of the connection between the sleeve 211 and the protruding end 212, and preventing the sleeve 211 from falling off from the protruding end 212, which would affect the sealing effect of the water inlet 115.

[0065] In this embodiment, the water outlet connecting channel 151 and the water outlet channel 150 are coaxial, that is, they have a common central axis M. Similarly, the water inlet connecting channel 141 and the water inlet channel 140 are coaxial, that is, they have a common central axis N.

[0066] Along the axial direction of the valve stem 200 ( Figure 5 The distance H1 from the central axis N of the water inlet connecting channel 141 and the water inlet channel 140 to the bottom of the water valve (i.e., the bottom of the cover body described later) is smaller than the distance H2 from the central axis M of the water outlet connecting channel 151 and the water outlet channel 150 to the bottom of the water valve. Under this arrangement, the pressure-bearing portion 110 is radially ( Figure 5 One side on the upper side (shown in the X direction) is arranged opposite to the water inlet connecting channel 141 to withstand the water flow pressure from the water inlet connecting channel 141. Since it extends downward for a short distance and is in a ring shape, it has better stability in withstanding water pressure, and the water flow pressure is also relatively stable.

[0067] However, those skilled in the art will appreciate that, in other embodiments, the distance H1 from the central axis N of the water inlet channel 140 to the bottom of the water valve may also be greater than or equal to the distance H2 from the central axis M of the water outlet channel 150 to the bottom of the water valve.

[0068] refer to Figures 3 to 6In the closed state of the water valve, the central axis M of the water outlet connecting channel 151 is substantially flush with the midline of the first rod portion 220 perpendicular to its axial direction. In the open state of the water valve, the top wall of the water outlet connecting channel 151 is substantially flush with the upper end of the first rod portion 220. In other words, in the process of switching from the closed state to the open state of the water valve, the first rod portion 220 moves axially relative to the water outlet connecting channel 151, and the moving distance is as follows: Figure 4 The axial distance d between the top wall of the water outlet connecting channel 151 and the upper end of the first rod portion 220 is shown.

[0069] like Figure 6 As shown, the valve stem 200 further includes a second stem portion 250 and a third stem portion 260, wherein the axial direction ( Figure 6 The upper and lower ends of the second rod portion 250 and the extended end 212 are respectively connected to the second rod portion 250 and the extended end 212.

[0070] like Figure 3 , Figure 4 and Figure 6 As shown, the outer diameter of the first rod portion 220 is smaller than the inner diameter of the valve channel 114, and a water outlet cavity 117 is defined between the valve channel 114 and the valve stem 200. In other words, a water outlet cavity 117 is formed between the outer wall of the first rod portion 220 and the inner wall of the valve channel 114, and the water outlet cavity 117 is ring-shaped.

[0071] Along the axial direction of the valve stem 200 ( Figure 6 A mounting portion 240 is provided between the second rod portion 250 and the stopper portion 230, and the mounting portion 240 is located in the valve channel 114. The radial dimension of the mounting portion 240 is smaller than the radial dimension of the stopper portion 230 and the radial dimension of the second rod portion 250, that is, the mounting portion 240 is recessed in the stopper portion 230 and the second rod portion 250 to form a groove 241 between the stopper portion 230 and the second rod portion 250, and the first sealing ring 242 is embedded in the groove 241, and the inner wall of the valve channel 114 squeezes the first sealing ring 242.

[0072] It is easy to understand that the first sealing ring 242 is elastic, and when the first sealing ring 242 is relaxed, the inner diameter of the first sealing ring 242 is smaller than the outer diameter of the mounting portion 240. The first sealing ring 242 is stretched open to be sleeved on the mounting portion 240 of the valve stem 200, with its inner periphery tightly attached to the outer wall of the mounting portion 240, and its outer periphery pressed against the inner wall of the valve channel 114, thereby achieving sealing between the valve stem 200 and the valve channel 114.

[0073] The second rod portion 250 is located above the first rod portion 220, which means that the first sealing ring 242 is located above the water outlet chamber 117, so that the connection gap between the valve stem 200 and the valve channel 114 is sealed above the water outlet chamber 117 to prevent water in the water outlet chamber 117 from flowing to the outside along the connection gap between the valve stem 200 and the valve channel 114 and affecting the user experience.

[0074] Specifically, refer to Figure 4 , Figure 6 and Figure 7 The pressing member 300 includes a first connecting portion 310 and a second connecting portion 320 connected to each other, and the second connecting portion 320 is clamped with the valve stem 200; the first connecting portion 310 is arranged around the second connecting portion 320, and the first connecting portion 310 and the second connecting portion 320 are radially ( Figure 4 The second connecting portion 320 and the inner wall of the first connecting portion 310 have a set spacing distance in the radial direction of the valve stem 200, and the spacing distance forms the slot 330 in a ring shape.

[0075] The first connection portion 310 includes a pressing portion 311. The pressing portion 311 is plate-shaped and extends in the radial direction ( Figure 4 The two ends of the upper surface of the pressing portion 311 gradually concave toward the center thereof, thereby forming a set arc on the upper surface of the pressing portion 311 to facilitate the user's pressing action and prevent the user's fingers from slipping off the two ends of the pressing portion 311 when pressing.

[0076] refer to Figure 3 and Figure 4 The above-mentioned valve body 100 also includes a mounting groove 160, which is arranged around the valve channel 114, and a portion of the first connecting portion 310 is inserted into the mounting groove 160. The upper end of the elastic member 400 is located in the slot 330 and abuts against the top wall of the slot 330, and the lower end of the elastic member 400 is located in the mounting groove 160.

[0077] A portion of the elastic member 400 is disposed around the second connection portion 320 , and a portion of the elastic member 400 is disposed around the inner wall 161 of the mounting groove, thereby ensuring the reliability of the connection of the elastic member 400 .

[0078] In this embodiment, the elastic member 400 is a spring, but those skilled in the art will appreciate that in other embodiments, other types of elastic members may be selected, such as rubber products, polyester products, and fiberglass products with elastic properties.

[0079] refer to Figure 4 , Figure 6 and Figure 7In some possible implementations, the second connecting portion 320 includes a plurality of circumferentially extending portions of the valve stem 200 ( Figure 7 A plurality of slots 261 are arranged at intervals along the circumferential direction thereof, and the plurality of slots 261 and the plurality of claws 321 correspond to each other one by one and are engaged with each other.

[0080] The plurality of claws 321 gradually gather from one end away from the slot 261 to one end contacting the slot 261. In other words, along the axial direction ( Figure 4 The radial dimension of the circular space enclosed by the connecting lines of the plurality of claws 321 in the horizontal plane gradually decreases, thereby facilitating the sleeve of a portion of the elastic member 400 outside the plurality of claws 321 from bottom to top.

[0081] As described above, from top to bottom, the claw 321 also has a set inclination compared to the axial direction of the valve stem 200. The inclined setting of the claw 321 generates compressive stress at the clamping point with the valve stem 200, and the connection between the pressing member 300 and the valve stem 200 is more reliable.

[0082] The upper end of the third rod portion 260 of the valve stem 200 is provided with a chamfered angle to facilitate its axial ( Figure 6 The third rod 260 is upwardly penetrated through the second connecting portion 320, and the slot 261 located at the lower end of the third rod portion 260 is engaged with the claw 321 located at the lower end of the second connecting portion 320, thereby forming a connection between the pressing member 300 and the valve stem 200, thereby pressing the pressing member 300, the pressing member 300 drives the valve stem 200 to move downward, and, under the elastic force of the elastic member 400, the pressing member 300 drives the valve stem 200 to move upward.

[0083] In this embodiment, if Figure 4 , Figure 6 and Figure 8 As shown, the valve stem 200 and the pressing member 300 are connected in a clamping manner, and are provided with 5 claws 321. Correspondingly, the outer wall of the valve stem 200 is also provided with 5 slots 261, that is, the pressing member 300 and the valve stem 200 have 5 connections, thereby ensuring the reliability of the connection between the two. However, those skilled in the art can understand that in other embodiments, other numbers of claws 321 and slots 261 can also be provided, such as 2, 3, 4, 6, etc. Further, the valve stem 200 and the pressing member 300 can also be connected by other connection methods, such as threaded connection, riveting, etc., as long as the valve stem 200 and the pressing member 300 are reliably connected.

[0084] refer to Figure 4 , Figure 7 and Fig. 9The outer wall of the first connecting portion 310 of the pressing member 300 is provided with a protruding portion along the axial direction of the valve stem 200 ( Figure 7 The guide rib 312 extends along the axial direction of the valve stem 200 (shown in the Z direction), and the groove wall of the installation groove 160 of the valve body 100 is provided with a guide groove 170 corresponding to the guide rib 312. The guide rib 312 is configured to move in the guide groove 170 along the axial direction of the valve stem 200. When the user presses the pressing portion 311 of the pressing member 300, the pressing member 300 moves downward, and the guide rib 312 moves synchronously in the guide groove 170, thereby ensuring that the pressing member 300 moves along the axial direction of the valve stem 200, and avoiding the displacement of the pressing member 300 during the downward movement due to the user applying force at different positions of the pressing portion 311.

[0085] like Figure 3 and Figure 4 As shown, in the closed state of the water valve, the lower end of the first connecting portion 310 of the pressing member 300 and the bottom wall of the mounting groove 160 are spaced apart, and the two are axially ( Figure 4 The first movable distance a is formed on the valve stem 200 (shown in the Z direction), the bottom of the second connecting portion 320 and the upper end of the valve channel 114 are arranged opposite to each other and spaced apart along the axial direction of the valve stem 200, and the two form a second movable distance b in the axial direction of the valve stem 200, and the sealing portion 210 of the valve stem 200 and the bottom of the water inlet chamber 130 are arranged opposite to each other and spaced apart along the axial direction of the valve stem 200, and the two form a third movable distance c in the axial direction of the valve stem 200. It is easy to understand that the pressing member 300 and the valve stem 200 are in a relatively fixed relationship in their axial direction, that is, the two move synchronously and their moving distances are also equal, and the above three movable distances restrict each other, and the minimum movable distance is the actual distance that the pressing member 300 and the valve stem 200 can move along their axial direction.

[0086] Specifically, in this embodiment, the first movable distance a is the minimum distance, and the third movable distance c is the maximum distance. When the water valve is in the open state, the lower end of the first connecting portion 310 of the pressing member 300 abuts against the bottom wall of the mounting groove 160. At this time, the distance moved by the pressing member 300 relative to the valve body 100 is the first movable distance a. The second connecting portion 320, which is a part of the pressing member 300, also moves down the first movable distance a. Since the second movable distance b is greater than the first movable distance a, the bottom of the second connecting portion 320 does not contact the upper port of the valve channel 114 at this time, and there is a gap between the two. Similarly, since the third movable distance c is greater than the first movable distance a, the sealing portion 210 of the valve stem 200 does not contact the bottom of the water inlet chamber 130, and there is an axial distance between the two. Therefore, although there are three movable distances regarding the axial moving distances of the pressing member 300 and the valve stem 200 in this embodiment, the actual moving distance is the minimum distance among the three movable distances.

[0087] refer to Figure 2 and Fig. 9The water inlet portion 111 of the valve body 100 includes a first reinforcing rib 171. The first reinforcing rib 171 is located on the outer wall of the water inlet portion 111. The first reinforcing rib 171 extends along the extension direction of the water inlet channel 140 ( Fig. 9 The first reinforcing rib 171 is illustratively in the shape of a rectangular parallelepiped, a portion of which is located on the outer wall of the water inlet portion 111, and the other portion extends into the mounting groove 160, that is, the first reinforcing rib 171 penetrates the outer wall of the main body 113 of the valve body 100, so as to enhance the stability of the connection between the water inlet portion 111 and the main body 113 through the first reinforcing rib 171, and avoid problems such as breakage between the water inlet portion 111 and the main body 113.

[0088] refer to Figure 2 , Figure 7 and Fig. 9 , the portion of the first reinforcing rib 171 located in the mounting groove 160 protrudes from the bottom wall of the mounting groove 160, and a first avoidance groove 313 is provided at the lower end of the first connecting portion 310 of the pressing member 300, and the first avoidance groove 313 is used to avoid the first reinforcing rib 171. Exemplarily, the first avoidance groove 313 is rectangular to match the shape of the first reinforcing rib 171. The first avoidance groove 313 is along the axial direction ( Figure 7 When the water valve is open, the pressing member 300 moves downward due to external force, and the first avoidance groove 313 avoids the first reinforcing rib 171 protruding from the bottom wall of the installation groove 160, so that the lower end of the first connecting portion 310 of the pressing member 300 abuts against the bottom wall of the installation groove 160.

[0089] Correspondingly, the outer wall of the water outlet 112 is provided with a second reinforcing rib 172, and the second reinforcing rib 172 is connected to the main body 113. The second reinforcing rib 172 is provided to enhance the stability of the connection between the water outlet 112 and the main body 113, and avoid problems such as breakage between the water outlet 112 and the main body 113.

[0090] In some possible implementations, reference Figure 2 , Figure 7 and Fig. 9 The water outlet 112 includes an inner tube section 118, which is located in the mounting groove 160 and protrudes from the bottom wall of the mounting groove 160. The lower end of the first connecting portion 310 of the pressing member 300 is provided with a second avoidance groove 314, which is used to avoid the inner tube section 118. Exemplarily, the cross section of the inner tube section 118 of the water outlet 112 is semicircular, and accordingly, the second avoidance groove 314 is also semicircular, which is along the axial direction ( Figure 7When the water valve is in the open state, the pressing member 300 is moved downward by the external force, and the second avoidance groove 314 avoids the inner tube section 118 protruding from the bottom wall of the installation groove 160, so that the lower end of the first connecting portion 310 of the pressing member 300 abuts against the bottom wall of the installation groove 160.

[0091] In some possible implementations, such as Figure 4 and Fig. 9 As shown, the bottom wall of the mounting groove 160 is provided with a Fig. 9 The plurality of protrusions 173 are spaced apart from each other (in the R direction in the middle), and the plurality of protrusions 173 are connected to the inner wall 161 of the mounting groove and spaced apart from the outer wall 162 of the mounting groove; the top surfaces of the plurality of protrusions 173 are in contact with the top surface of the first reinforcing rib 171 and the vertex of the inner tube section 118 along the axial direction of the valve stem 200 ( Fig. 9 The end of the elastic member 400 located in the mounting groove 160 abuts against the plurality of protrusions 173, the first reinforcing rib 171 and the inner tube section 118.

[0092] That is, the plurality of protrusions 173, the first reinforcing rib 171 and the inner tube section 118 jointly receive the elastic member 400. Exemplarily, the plurality of protrusions 173 are connected to the inner wall 161 of the mounting groove and are spaced apart from the outer wall 162 of the mounting groove, so that the elastic member 400 is disposed around the inner wall 161 of the mounting groove, and the first connecting portion 310 of the pressing member 300 is inserted between the protrusion 173 and the outer wall 162 of the mounting groove to abut against the bottom wall of the mounting groove 160.

[0093] In some possible implementations, such as Fig. 9 As shown, the outer walls of the water inlet portion 111 and the water outlet portion 112 each include a plurality of reducer tubes 119 connected in sequence, along the radial direction ( Fig. 9 The outer diameter of each reducer 119 gradually decreases in the direction away from the main body 113. When the outer walls of the water inlet 111 and the water outlet 112 are sleeved with external water pipes, the provision of multiple reducers 119 can enhance the reliability of the connection and avoid the problem of water pipe falling off.

[0094] refer to Figure 2 , Figure 4 , Fig. 9 and Fig.10The water valve further comprises a cover 120, and the lower end of the main body 113 of the valve body 100 comprises an opening 131, the inner diameter of the opening 131 is larger than the outer diameter of the sealing portion 210 of the valve stem 200, and the cover 120 is threadedly connected to the valve body 100 and seals the opening 131 of the main body 113. That is, the cover 120 is detachably connected to the main body 113 of the valve body 100, and the inner diameter of the opening 131 is larger than the outer diameter of the sealing portion 210 of the valve stem 200, so that it is easy to remove the cover 120 and install the valve stem 200 from bottom to top into the valve passage 114.

[0095] Specifically, the cover 120 includes a sealing groove 121 and a water storage cavity 122. The sealing groove 121 is arranged around the water storage cavity 122. The lower end of the main body 113 is along the axial direction of the valve stem 200 ( Figure 4 The cover body 120 is connected to the main body 113 to define a water inlet chamber 130. The water storage chamber 122 of the cover body 120 serves as a part of the water inlet chamber 130 and has the functions of storing water and supplying water.

[0096] In some possible implementations, reference Figure 2 , Figure 4 , Fig.10 The sealing groove 121 contains a second sealing ring 174, and the lower end of the main body 113 squeezes the second sealing ring 174. The second sealing ring 174 seals the water inlet cavity 130, thereby preventing the water in the water inlet cavity 130 from leaking from the connection between the cover body 120 and the main body 113, which affects the user experience.

[0097] In some possible implementations, reference Figure 3 , Figure 4 , Fig. 9 and Fig.10 The radial dimension of the inner side wall 124 of the sealing groove gradually decreases from close to the bottom wall 126 of the sealing groove to away from the bottom wall 126 of the sealing groove, so that the second sealing ring 174 is easily mounted on the inner side wall 124 of the sealing groove from top to bottom, and during the connection process of the main body 113 and the cover body 120, the lower end of the main body 113 presses down the second sealing ring 174 to move it down to the bottom wall 126 of the sealing groove, so as to form the bottom wall 126 of the sealing groove, the inner side wall 124 of the sealing groove and the lower end of the main body 113 to squeeze the second sealing ring 174, thereby achieving a better sealing effect.

[0098] It is easy to understand that the second sealing ring 174 only contacts the inner side wall 124 of the sealing groove when not sealing, and does not move down to the bottom wall 126 of the sealing groove. When sealing, the second sealing ring 174 is pressed down by the main body 113 and contacts the inner side wall 124 and the bottom wall 126 of the sealing groove at the same time, thereby forming an extrusion of the second sealing ring 174 by the bottom wall 126 of the sealing groove, the inner side wall 124 of the sealing groove and the main body 113.

[0099] Exemplarily, the outer wall of the cover body 120 is provided with a concave-convex structure to facilitate the staff to unscrew or tighten the cover body 120 to separate or assemble it from the main body 113.

[0100] like Figures 2 to 4 as well as Figure 6 As shown, the assembly process of the water valve of the embodiment of the present application is as follows: first, the first sealing ring 242 is embedded in the groove 241, the sleeve 211 is sleeved on the protruding end 212, the upper half of the elastic member 400 is installed into the slot 330, or the lower half of the elastic member 400 is installed into the mounting groove 160, and then the lower end of the pressing member 300 is inserted into the mounting groove 160 along the axial direction of the valve stem 200, the valve stem 200 extends from the opening 131 of the main body 113 into the valve channel 114, the valve stem 200 is engaged with the claw 321 of the pressing member 300, and finally the cover body 120 is installed on the main body 113.

[0101] So far, the present application has satisfactorily described the structure of a water valve, which releases water by pressing, has a simple structure, is easy to assemble, and has a low cost.

[0102] Those skilled in the art will appreciate that the technical solution of this water valve can be applied to almost all scenarios where water switches need to be controlled, such as toys and boat accessories in the field of leisure and entertainment, agricultural irrigation in the field of agriculture, dust prevention and disinfection in the industrial field, and so on.

[0103] The exemplary embodiments disclosed in the present application may be subjected to various substitutions, combinations or modifications. Without departing from the essence of the present application, all of these modifications still belong to the concept of the present application and fall within the scope of protection defined by the claims of the present application.
