[0065] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be arbitrarily combined with each other.

[0066] Please combine them together Figures 1 to 4 , Figures 6 to 8 , Figure 10 , Figure 12 , Figure 14 , Figure 15 , Figure 18 , Figure 20 and Figure 21 This disclosure presents a push-button water dispensing device. The push-button water dispensing device can be, but is not limited to, a spray gun, a pull-out faucet, or a handheld showerhead with a spray gun function. For ease of description, a spray gun will be used as an example of the push-button water dispensing device.

[0067] The push-button water dispenser includes a body 10, a movable component 20, a reset component 30, and a button 40. The body 10 has a guide hole 100 and a water outlet channel 200 penetrating the body 10. The guide hole 100 communicates with the water outlet channel 200. The movable component 20 is movably mounted in the water outlet channel 200 and has a connecting portion 21. The movable component 20 passes through the guide hole 100, with the connecting portion 21 positioned on the side of the guide hole 100 opposite to the water outlet channel 200. The button 40 is hinged to the body 10 and has a groove 300. At least one end of the groove 300 penetrates the button 40, the connecting portion 21 is mounted in the groove 300, and the reset component 30 is clamped between the button 40 and the body 10. In this embodiment, the guide hole 100 facilitates the guiding engagement between the movable component 20 and the body 10. The sliding component 20 passes through the guide hole 100, ensuring that the mating position of the connecting part 21 and the button 20 is outside the water outlet channel 200, reducing interference from water on the engagement between the connecting part 21 and the button 20. It can be understood that in other embodiments, the body 10 may not have the guide hole 100, and the movable component 20 can be guided and engaged with the body 10 through the water outlet channel 200. Alternatively, the body 10 may also be provided with a guide groove or guide protrusion, etc., to guide and engage with the sliding component 20, improving the movement accuracy of the sliding component 20 relative to the body 10.

[0068] The button 40 is configured to rotate relative to the body 10, so that the connecting part 21 slides relative to the slide groove 300, causing the movable component 20 to move along the water outlet channel 200, switching the water outlet channel 200 from closed to open, and compressing the reset member 30 to generate the driving force for the button 40 to reset.

[0069] It can be understood that in other embodiments, the push-button water dispensing device may not include the reset member 30. The reset of button 40 can also be achieved by hydraulically driving the movable component 20, which in turn drives button 40 to reset. That is, when button 40 rotates relative to the body 10, it needs to resist water resistance, thereby driving the movable component 20 to move along the water outlet channel 200, switching the water outlet channel 200 from closed to open. When the external force acting on button 40 is removed, under the drive of water, the movable component 20 moves along the water outlet channel 200, switching the water outlet channel 200 from open to closed, and driving button 40 to reset. The push-button water dispensing device can also be equipped with a control structure (e.g., a valve structure) to control the water entering the water outlet channel 200, thereby stopping the water supply to the push-button water dispensing device.

[0070] The main body 10 can be a one-piece structure or a split structure. In this embodiment, the main body 10 includes a housing 11 and a water outlet 12. One end of the housing 11 can be connected to a pipeline to introduce water into the water outlet channel 200. The housing 11 and the pipeline can be connected by, but not limited to, threaded connection, ultrasonic welding, bonding, or snap-fit. The water outlet 12 is disposed at the other end of the housing 11, and the water outlet channel 200 can form a water outlet hole 201 on the water outlet 12. The water outlet 12 and the housing 11 can be connected by, but not limited to, threaded connection, ultrasonic welding, bonding, or snap-fit. A sealing structure 13 can also be provided between the water outlet 12 and the housing 11 to improve the sealing performance between them.

[0071] The push-button water dispensing device disclosed in this embodiment includes a body 10 having a guide hole 100 and a water outlet channel 200, a movable component 20 movably mounted in the water outlet channel 200, a reset component 30, and a button 40 hinged to the body 10. The movable component 20 has a connecting portion 21 located on the side of the guide hole 100 opposite to the water outlet channel 200. The button 40 has a groove 300 with at least one end penetrating through it, and the connecting portion 21 can be mounted in the groove 300 through the end of the button 40. During the rotation of the button 40 relative to the body 10, the connecting portion 21 slides relative to the groove 300, causing the movable component 20 to move along the water outlet channel 200, switching the water outlet channel 200 from closed to open. This avoids the need to use pins or tools to connect the button 40 to the movable component 20, resulting in a simple assembly structure and lower cost. Furthermore, during the above process, the reset member 30 can be compressed by the button 40 to generate the driving force for the button 40 to reset. Then, under the drive of the reset member 30, the button 40 reset drive active component 20 will close the water outlet channel 200 again, thereby facilitating the switching of the water outlet channel 200 between closed and open states.

[0072] In the exemplary embodiments, please refer to Figure 7 , Figure 10 , Figure 15 and Figure 20 The button 40 has a groove wall 14 forming a slide groove 300, which fits against the connecting part 21. This fit between the groove wall 14 and the connecting part 21 improves the transmission between the button 40 and the moving component 20, resulting in smoother control of the moving component 20 by the button 40. Furthermore, it prevents gaps between the groove wall 14 and the connecting part 21, thus avoiding increased wear and noise.

[0073] In the exemplary embodiments, please refer to Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 10 , Figure 12 , Figure 14 , Figure 15 , Figure 18 , Figure 20 and Figure 21 The movable component 20 includes a valve stem 22, and a connecting part 21 is disposed at one end of the valve stem 22. The connecting part 21 includes a ball head 211 and a connecting rod 212 connecting the ball head 211 and the valve stem 22. The ball head 211 and the connecting rod 212 are coaxially arranged, and the radial dimension of the ball head 211 is larger than the radial dimension of the connecting rod 212. The groove wall 14 includes an inner groove surface 141 and a groove opening surface 142 located at the opening of the slide groove 300. The inner groove surface 141 fits against the ball head 211, and the groove opening surface 142 fits against the connecting rod 212. This allows the connecting part 21 to fit against the inner groove surface 141 and the groove opening surface 142 respectively after it is installed in the slide groove 300. Since the radial dimension of the ball head 211 is larger than the radial dimension of the connecting rod 212, the button 40 can limit the connection part 21, ensuring that the connection part 21 can be stably placed within the slide groove 300. Furthermore, the inner groove surface 141 fits against the ball head 211, and the groove opening surface 142 fits against the connecting rod 212, which further increases the contact area between the button 40 and the connecting part 21, and further improves the transmission stability between the button 40 and the movable component 20. The ball head 211 provides greater freedom between the connecting part 21 and the button 40. The angle between the extension direction of the slide groove 300 and the connecting part 21 can be adjusted according to the rotational position of the button 40 relative to the body 10 and the sliding position of the movable component 20 relative to the body 10, making the movement of the connecting part 21 relative to the slide groove 300 smoother. In this embodiment, the connecting rod 212 is cylindrical, so that the connecting rod 212 can still fit against the groove opening surface 142 when the connecting part 21 is twisted by force.

[0074] In the exemplary embodiments, please refer to Figure 7 , Figure 10 , Figure 15 and Figure 20 The slide groove 300 passes through the end of the button 40 and gradually expands outwards towards the end of the button 40. This facilitates the positioning of the connecting part 21 with the slide groove 300 and makes it easier for the connecting part 21 to be installed in the slide groove 300. Figure 7 As shown, the two inner groove surfaces 141 and the two groove opening surfaces 142 gradually expand, causing the end of the slide groove 300 that passes through the button 40 to gradually expand outward. Figure 15 As shown, the two inner groove surfaces 141 gradually unfold, causing the end of the slide groove 300 that passes through the button 40 to gradually expand outward.

[0075] In the exemplary embodiments, please refer to Figure 2 , Figure 3 , Figure 11 , Figure 13 and Figure 14The water outlet channel 200 has a narrowing section 202, at which the flow area of ​​the water outlet channel 200 is reduced. In this way, the narrowing section 202 can facilitate the movable component 20 to block the water outlet channel 200 and close the water outlet channel 200.

[0076] The movable component 20 also includes a first sealing ring 23, which is fitted onto the valve stem 22. During the rotation of the button 40 relative to the body 10, the first sealing ring 23 cooperates with the valve stem 22 to seal the narrowed section 202 or allow water to pass through it. Thus, the first sealing ring 23, through its elastic deformation capability, can better fit with the body 10, ensuring reliable sealing of the water outlet channel 200. To improve the connection stability between the first sealing ring 23 and the valve stem 22, a first annular groove 400 for mounting the first sealing ring 23 is provided on the axial outer side of the valve stem 22.

[0077] In the exemplary embodiments, please refer to Figure 11 and Figure 13 The body 10 has an annular surface 15 that encloses and forms a narrowing section 202. The annular surface 15 is inclined relative to the axial direction of the narrowing section 202 and faces the first sealing ring 23. This makes the annular surface 15 easy to position the movable component 20 and facilitates guiding the first sealing ring 23 to the narrowing section 202. Furthermore, the annular surface 15 increases the contact area between the body 10 and the first sealing ring 23 and can compress the first sealing ring 23, further improving the reliability of sealing the water outlet channel 200. In this embodiment, the first sealing ring 23 is annular, and the annular surface 15 is conical. In some embodiments, the first sealing ring 23 may also be other annular structures. The contour of the annular surface 15 matches the first sealing ring 23.

[0078] In the exemplary embodiments, please refer to Figure 3 , Figure 11 and Figure 13 The valve stem 22 has a gradually narrowing section 221 on its outer circumferential side. The gradually narrowing section 221 is located on the side of the first sealing ring 23 facing the annular surface 15, and gradually narrows from the first sealing ring 23 towards the narrowing section 202. This gradually narrowing section 221 facilitates positioning with the annular surface 15, thereby ensuring the stability of the fit between the first sealing ring 23 and the annular surface 15, and further improving the reliability of sealing the water outlet channel 200.

[0079] In the exemplary embodiments, please refer to Figure 10 and Figure 20The main body 10 has an inner wall 16 that encloses and forms a sliding space 500. A guide hole 100 communicates with the water outlet channel 200 through the sliding space 500. The valve stem 22 passes through the guide hole 100 via the sliding space 500. This sliding space 500 increases the contact area between the movable component 20 and the main body 10, allowing the inner wall 16 to guide the movement of the movable component 20 and improving its stability. Furthermore, increasing the contact area between the movable component 20 and the main body 10 facilitates sealing of the guide hole 100. In this embodiment, the movable component 20 also includes a second sealing ring 24, which is sleeved on the valve stem 22 and accommodated in a sliding seal between the sliding space 500 and the inner wall 16. This second sealing ring 24, with its elastic deformation capability, better fits the inner wall 16, ensuring a seal on the side of the sliding space 500 facing the guide hole 100 and preventing water from draining out of the guide hole 100 through the sliding space 500. To improve the connection stability between the second sealing ring 24 and the valve stem 22, a second annular groove 600 for the installation of the second sealing ring 24 is provided on the outer axial side of the valve stem 22.

[0080] In the exemplary embodiments, please refer to Figure 2 , Figure 3 , Figure 8 , Figure 12 , Figure 14 , Figure 16 , Figure 18 and Figure 21 The reset element 30 is a spring. The button 40 and the body 10 are respectively provided with a first positioning part 41 and a second positioning part 17, and the two ends of the spring are respectively positioned and connected to the first positioning part 41 and the second positioning part 17. The arrangement of the first positioning part 41 and the second positioning part 17 improves the connection stability between the spring and the button 40 and the body 10, thereby ensuring the reliability of the spring-driven button 40 reset. In this embodiment, both the first positioning part 41 and the second positioning part 17 are protruding structures, and the two ends of the spring are respectively sleeved on the protruding structures. It can be understood that in other embodiments, at least one of the first positioning part 41 and the second positioning part 17 can also be a groove structure, and the end of the spring can be installed in the groove structure. Furthermore, in other embodiments, the reset element 30 can also be, but is not limited to, a spring sheet or a torsion spring.

[0081] In the exemplary embodiments, please refer to Figure 2 , Figure 4 , Figure 8 , Figure 12 , Figure 14 , Figure 16 , Figure 18 and Figure 21The main body 10 has a mounting groove 700, and the button 40 is mounted in the mounting groove 700 and rotates relative to the main body 10 along the mounting groove 700. In this way, the mounting groove 700 restricts the rotation path of the button 40, improves the stability of the button 40's rotation relative to the main body 10, and reduces external interference to the rotation of the button 40 relative to the main body 10.

[0082] The mounting groove 700 forms a first groove surface 181 and two second groove surfaces 182 on the body 10. The first groove surface 181 is located on the rotation path of the button 40. After the reset member 30 drives the button 40 to reset, the button 40 is limited and connected to the first groove surface 181. In this way, when subjected to an external force not driven by the reset member 30, the button 40 can be prevented from rotating too much, causing the reset member 30 to be stretched and plastically deformed, thus affecting the elastic deformation capability of the reset member 30. Both second groove surfaces 182 are parallel to the plane of the rotation path.

[0083] In the exemplary embodiments, please refer to Figure 14 and Figure 16 The second groove surface 182 is provided with a limiting protrusion 183, and the button 40 is provided with a clearance space 1000. The button 40 is installed in the mounting groove 700, and the limiting protrusion 183 is placed in the clearance space 1000. In this way, the setting of the clearance space 1000 allows the button 40 to rotate within a certain angle range relative to the body 10, ensuring that the water outlet channel 200 can switch between closed and open during the rotation of the button 40 relative to the body 10. After the reset component 30 drives the button 40 to reset, the button 40 is limited and connected to the limiting protrusion 183. In this way, the setting of the limiting protrusion 183 can improve the limiting effect on the button 40, and prevent the reset component 30 from being stretched and plastically deformed due to excessive rotation angle of the button 40, which would affect the elastic deformation capability of the reset component 30. In this embodiment, the limiting protrusion 183 has a strip-shaped structure, and the button 40 has a mating surface 42 on the side facing the clearance space 1000. The mating surface 42 can fit with the limiting protrusion 183 to form a limiting fit.

[0084] In the exemplary embodiments, please refer to Figure 5 , Figure 6 and Figure 9 Each of the two second groove surfaces 182 is provided with a hinge protrusion 184, which is received in the mounting groove 700 and is arranged opposite to each other. The button 40 is provided with two spaced connecting walls 43, and the connecting walls 43 are provided with through holes 800.

[0085] During the installation of button 40 in mounting slot 700, the two hinge protrusions 184 slide and abut against the two connecting walls 43 in a one-to-one correspondence, driving the two connecting walls 43 to undergo elastic deformation and gradually move closer together until the two hinge protrusions 184 slide into the two through holes 800 in a one-to-one correspondence, and the two connecting walls 43 are reset. Button 40 is hinged to body 10 through the interaction and cooperation of connecting walls 43 and hinge protrusions 184. Due to the circumferential closure of through holes 800, the connecting walls 43 and hinge protrusions 184 are not easily separated after connection, improving the connection stability between button 40 and body 10. In this embodiment, due to molding reasons, the cross-section of hinge protrusion 184 is not a complete circle, and correspondingly, the cross-section of through hole 800 is not a complete circle, requiring local clearance for hinge protrusion 184.

[0086] In the exemplary embodiments, please refer to Figure 5 , Figure 6 and Figure 9 Each of the two hinge protrusions 184 has an inclined surface 1841 on one side facing the opposite direction of the button 40. This inclined surface 1841 facilitates the sliding of the connecting wall 43 relative to the inclined surface 1841, allowing it to gradually undergo elastic deformation, thus facilitating the assembly of the connecting wall 43 with the hinge protrusion 184. A guide surface 431 can also be provided on the side of the connecting wall 43 facing the inclined surface 1841. The guide surface 431 is arranged around the circumference of the connecting wall 43, narrowing its circumference. This facilitates sliding with the inclined surface 1841 and enhances the elastic deformation capability of the connecting wall 43 in the circumferential direction, further facilitating the assembly of the connecting wall 43 with the hinge protrusion 184.

[0087] In the exemplary embodiments, please refer to Figure 14 , Figure 17 and Figure 19 The first groove surface 181 is provided with a slot 900, which is connected to the mounting groove 700. The button 40 is provided with a connecting shaft 44. The button 40 is installed in the mounting groove 700, and the connecting shaft 44 is snapped into the slot 900. The button 40 is hinged to the body 10 through the connecting shaft 44.

[0088] The first groove surface 181 is provided with a recessed surface 185, which extends along the hinge axis between the button 40 and the body 10. In this way, the recessed surface 185 facilitates the positioning of the connecting shaft 44 and the body 10.

[0089] At least three clamping arms 186, alternately arranged along the hinge axis, are provided on both sides of the recessed surface 185 perpendicular to the hinge axis. The at least three clamping arms 186 and the recessed surface 185 together form a slot 900. Thus, the at least three clamping arms 186 provide clamping force to the hinge axis on both sides perpendicular to the hinge axis, ensuring the connection stability between the button 40 and the body 10. Furthermore, the elastic deformation capability of the clamping arms 186 facilitates the engagement of the connecting shaft 44 with the slot 900. In this embodiment, the connecting shaft 44 includes a shaft segment 441 and a connecting arm 442, both extending along the hinge axis. The shaft segment 441 is connected to the button 40 via the connecting arm 442. The orthographic projections of the clamping arms 186 on both sides of the recessed surface 185 perpendicular to the hinge axis do not overlap along the hinge axis direction, and there is a gap between the orthographic projections.

[0090] During the rotation of button 40 relative to slot 900, shaft segment 441 can rotate relative to slot 900, and connecting arm 442 can swing relative to hinge axis. The orthographic projection of connecting arm 442 along the hinge axis direction is located within the aforementioned gap, so that clamping arms 186 on both sides perpendicular to the hinge axis direction can limit the swing range of connecting wall 43, further preventing button 40 from rotating too much and causing reset member 30 to be stretched and plastically deformed, thus affecting the elastic deformation capability of reset member 30.
