The movement of the movable member can drive the first pressing surface to move the pressure relief valve core from the third position to the fourth position, and drive the second pressing surface to move the main valve core from the first position to the second position.

When the movable member is pressed, the connecting pipe can move from the fifth position to the sixth position, and sequentially push the pressure relief valve core and the main valve core during the movement from the fifth position to the sixth position, so as to open the main water path; wherein, when the main water path is opened, the water in the main water outlet cavity enters the nozzle through the connecting pipe.

Detailed implementation mode

[0043] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined arbitrarily with each other.

[0044] An embodiment of this application provides a valve structure, as Figures 1 - 12 shown. The valve structure 1 includes: a valve body 11, a main valve core 12 and a pressure - relief valve core 13 located inside the valve body 11, and further includes a first spring 16 that applies an elastic force to the main valve core 12 and a second spring 17 that applies an elastic force to the pressure - relief valve core 13;

[0045] The valve body 11 is provided with a main water path having a main water inlet and a main water outlet. The main valve core 12 is arranged to block the main water path when located at the first position and open the main water path when moving from the first position to the second position;

[0046] A pressure - relief water path having a pressure - relief water inlet and a pressure - relief water outlet is arranged inside the main valve core 12. The pressure - relief valve core 13 is arranged to close the pressure - relief water path when located at the third position and open the pressure - relief water path when moving from the third position to the fourth position. When the pressure - relief water path is opened, it communicates the main water inlet and the main water outlet;

[0047] Among them, the moving direction of the main spool valve 12 from the first position to the second position is the same as the moving direction of the pressure relief spool valve 13 from the third position to the fourth position. When opening the main waterway, the pressure relief spool valve 13 is set to be pressurized and move first. After moving from the third position to the fourth position (at this time the pressure relief waterway is opened), the main spool valve 12 is pressurized and moves from the first position to the second position (at this time the main waterway is opened); when closing the main waterway, the main spool valve 12 and the pressure relief spool valve 13 are released. The main spool valve 12 is reset to the first position under the action of the first spring 16, and the pressure relief spool valve 13 is reset to the third position under the action of the second spring 17.

[0048] Since the moving direction of the main spool valve 12 from the first position to the second position is the same as the moving direction of the pressure relief spool valve 13 from the third position to the fourth position, in this way, the same pressing component can be used to push the main spool valve 12 and the pressure relief spool valve 13, that is, the main spool valve 12 and the pressure relief spool valve 13 are pushed by the pressing component in the same direction. The pressing component has a first pressing surface corresponding to the main spool valve 12 and a second pressing surface corresponding to the pressure relief spool valve 13. When the pressing component moves towards the main spool valve 12 and the pressure relief spool valve 13, the second pressing surface first contacts the pressure relief spool valve 13 and pushes the pressure relief spool valve 13 from the third position to the fourth position, and then the first pressing surface contacts the main spool valve 12 and pushes the main spool valve 12 from the first position to the second position. The control method of this valve structure 1 is simple, and the pressing component can be used to push the pressure relief spool valve 13 and the main spool valve 12 in sequence in one direction.

[0049] In the solution provided by the embodiment of the present application, the pressure relief spool valve 13 is first pushed from the third position to the fourth position, so that after the pressure relief spool valve 13 opens the pressure relief waterway, the main water inlet and the main water outlet are communicated. Thus, the pressures at both ends of the main spool valve 12 are the same. At this time, it is relatively easy to push the main spool valve 12, and a relatively small force can be used to move the main spool valve 12 from the first position to the second position, so as to easily open the main waterway. The valve structure 1 provided by the present application can be used in a cup washer. The cup washer adopting this valve structure 1 can relatively easily control the opening and closing of the waterway, thereby effectively overcoming the problem that the cup washer in the prior art requires a relatively large pressing force to open the waterway. It can be understood that the valve structure provided by the present application is not limited to being applied to a cup washer, and other devices that need to open the waterway in a labor-saving manner can all adopt it.

[0050] In one embodiment, as Figures 3 - 8As shown, the main water passage in the valve body 11 includes a first tapered pipe section 113. The cross-section of the first tapered pipe section 113 gradually shrinks in the direction towards the main water outlet. A first seal 14 is sleeved on the outer periphery of the main valve core 12. When the main valve core 12 is in the first position, the main valve core 12 presses the first seal 14 against the first tapered pipe section 113 under the action of the first spring 16, so that the main water passage is shut off. When pressure is applied to the main valve core 12 to move the main valve core 12 from the first position to the second position, the main valve core 12 drives the first seal 14 away from the first tapered pipe section 113, so that the main water passage is opened, and the main water passage is opened.

[0051] The pressure relief water passage in the main valve core 12 includes a second tapered pipe section 127. The cross-section of the second tapered pipe section 127 gradually shrinks in the direction towards the pressure relief water outlet. A second seal 15 is sleeved on the outer periphery of the pressure relief valve core 13. When the pressure relief valve core 13 is in the third position, the pressure relief valve core 13 presses the second seal 15 against the second tapered pipe section 127 under the action of the second spring 17, so that the pressure relief water passage is shut off. When pressure is applied to the pressure relief valve core 13 to move the pressure relief valve core 13 from the third position to the fourth position, the pressure relief valve core 13 drives the second seal 15 away from the second tapered pipe section 127, so that the pressure relief water passage is opened.

[0052] Among them, Figure 3 and Figure 8 In the examples of, the main water outlet is located at the upper end of the valve body 11, the main water inlet is located at the lower end of the valve body 11. The main water passage includes a main water inlet cavity 111 with a main water inlet and a main water outlet cavity 112 with a main water outlet. The first tapered pipe section is between the main water inlet cavity 111 and the main water outlet cavity 112. The upper end of the main valve core 12 is the pressure relief water outlet, and the lower end is the pressure relief water inlet. The pressure relief water passage includes a pressure relief water inlet cavity 125 with a pressure relief water inlet and a pressure relief water outlet cavity 126 with a pressure relief water outlet. The second tapered pipe section 127 is between the pressure relief water inlet cavity 125 and the pressure relief water outlet cavity 126.

[0053] It can be understood that the above ways are not limited to sealing the main water passage and the pressure relief water passage. For example, in other embodiments, when the main valve core 12 moves to the second position, the main water passage can be disconnected by blocking the main water inlet or the main water outlet, and when the pressure relief valve core 13 moves to the fourth position, the pressure relief water passage can be disconnected by blocking the pressure relief water inlet or the pressure relief water outlet.

[0054] In one embodiment, such as Figure 4As shown, the main waterway includes a main water inlet chamber 111 having a main water inlet. A limiting ring 19 with a guiding hole 191 is arranged in the main water inlet chamber 111. The main valve core 12 is connected with a guiding column 18. The guiding column 18 is movably inserted into the guiding hole 191. Thus, the movement of the main valve core 12 can be guided through the cooperation between the guiding column 18 and the guiding hole 191, and the arrangement of the limiting ring 19 can prevent the main valve core 12 from disengaging from the main water inlet. Among them, the first spring 16 can be arranged to sleeve on the guiding column 18, with one end abutted against the main valve core 12 and the other end abutted against the limiting ring 19, so as to apply an elastic force to the main valve core 12 in the direction towards the main water outlet.

[0055] Figure 4 It is shown that the limiting ring 19 can be installed in the water inlet pipe section of the main water inlet through a threaded connection manner. Of course, it can also be installed in the water inlet pipe section through an interference fit manner.

[0056] In Figure 4 the example, the water at the main water inlet enters the main water inlet chamber 111 through the guiding hole 191. To avoid the guiding column 18 blocking the waterway, an internal cavity 184, a first opening 181 communicating with the internal cavity 184, a second opening 182 and a third opening 183 are arranged in the guiding column 18. The first opening 181 is located at one end of the guiding column 18 inserted into the guiding hole 191. The second opening 182 communicates with the pressure relief water inlet, and the third opening 183 communicates the inside and outside of the guiding column 18. Among them, the water at the main water inlet passes through the guiding hole 191 and enters the internal cavity 184 of the guiding column 18 from the first opening 181, and the water in the internal cavity 184 flows out from the second opening 182 and the third opening 183.

[0057] Figure 9 (Combined with Figure 4 ) It shows the main valve core 12 in an embodiment. One end of the main valve core 12 has a first pressure-receiving surface 121 and a first annular groove 122 is arranged on the outer peripheral surface. The first sealing ring 14 for abutting against the first tapered pipe section 113 is arranged in the first annular groove 122. A stop portion 123 is arranged on the side of the first annular groove 122 away from the first pressure-receiving surface 121. A threaded portion 124 is arranged on the side of the stop portion 123 away from the first annular groove 122. The threaded portion 124 is used to connect the guiding column 18. When the first spring 16 sleeves on the guiding column 18, one end abuts against the stop portion 123 and the other end abuts against the end surface of the limiting ring 19 surrounding the guiding hole 191. When the main valve core 12 is located in the valve body 11, the end of the main valve core 12 with the first pressure-receiving surface 121 is located in the main water outlet chamber 112, and the end with the threaded portion 124 is located in the main water inlet chamber 111. The first sealing ring 14 installed in the first annular groove 122 is close to the first tapered pipe section 113.

[0058] It can be understood that the structure of the main valve core 12 and the guiding installation method of the main valve core 12 in the valve body 11 are not limited to the above-mentioned method, and there can be many changes. For example, a guide rib can also be provided on the outer surface of the main valve core 12, and the guide rib slides in cooperation with the slide groove on the inner wall of the main water inlet chamber 111.

[0059] In one embodiment, Figure 10 As shown (combined Figure 4 ), the pressure relief waterway includes a pressure relief water inlet chamber 125 having a pressure relief water inlet and a pressure relief water outlet chamber 126 having a pressure relief water outlet, the pressure relief valve core 13 includes a guide portion 133 that cooperates with the inner wall of the pressure relief water inlet chamber 125 and a connecting column 134 connected to the side of the guide portion 133 facing away from the pressure relief water outlet, the cross section of the connecting column 134 is smaller than the cross section of the guide portion 133, the second spring 17 is sleeved on the connecting column 134, and one end is pressed against the guide portion 133, and the other end is pressed against the guide column 18, as shown Figure 4 As shown, a groove for positioning the second spring 17 is provided at the position of the guide column 18 having the second opening 182 .

[0060] Figure 10 The pressure relief valve core 13 in one embodiment is shown. One end of the pressure relief valve core 13 is provided with a second pressure-bearing surface 131, and a second annular groove 132 is provided on the outer circumference. The second annular groove 132 is used to mount the second sealing ring 15. A guide portion 133 and a connecting post 134 are provided on the side of the second annular groove 132 of the pressure relief valve core 13 away from the second pressure-bearing surface 131. When the pressure relief valve core 13 is installed in the main valve core 12, the end of the pressure relief valve core 13 with the second pressure-bearing surface 131 extends out of the pressure relief water outlet chamber 126 to facilitate pressing. The guide portion 133 and connecting post 134 are located in the pressure relief water inlet chamber 125. The second sealing ring 15 in the second annular groove 132 is close to the second tapered pipe section 127.

[0061] In one embodiment, Figures 3 - 8 As shown, the main valve core 12 has a first pressure-receiving surface 121 for receiving pressure, and the pressure relief valve core 13 has a second pressure-receiving surface 131 for receiving pressure. The end of the pressure relief valve core 13 with the second pressure-receiving surface 131 protrudes from the first pressure-receiving surface 121. In this way, the second pressure-applying surface of the pressure-applying component can first contact the second pressure-receiving surface 131. After the pressure relief valve core 13 moves to the fourth position, the first pressure-applying surface of the pressure-applying component then presses against the first pressure-receiving surface 121.

[0062] By arranging the second pressure-bearing surface 131 to protrude from the first pressure-bearing surface 121 , the first pressing surface of the pressure member for pressing the first pressure-bearing surface 121 and the second pressing surface for pressing the second pressure-bearing surface 131 can be arranged on the same plane.

[0063] In another embodiment, the second pressure-receiving surface 131 may be flush with or even lower than the first pressure-receiving surface 121. In this case, the second pressing surface of the pressing member may be provided to protrude from the first pressing surface, as long as the second pressing surface can first contact the second pressure-receiving surface 131 to push the pressure-relief valve core 13 to the fourth position.

[0064] An embodiment of the present application further provides a cup washer, including a water spraying mechanism 2, a movable member 4, and the valve structure 1 as described above. The main water outlet of the valve structure 1 is communicated with the water inlet passage of the water spraying mechanism 2.

[0065] Wherein, the movable member 4 is arranged to be movable relative to the valve body 11 when being pressed. The movement of the movable member 4 can drive the first pressing surface 261 to move the pressure-relief valve core 13 from the third position to the fourth position, and drive the second pressing surface 262 to move the main valve core 12 from the first position to the second position. When the movable member 4 is released, the pressure-relief valve core 13 is reset from the fourth position to the third position, and the main valve core 12 is reset from the second position to the first position.

[0066] In some embodiments, the movable member 4 may be connected to a pressing member having a first pressing surface 261 and a second pressing surface 262. The movement of the movable member 4 can drive the pressing member to move, thereby pushing the pressure-relief valve core 13 and the main valve core 12. The movable member 4 may also be a pressing member having a first pressing surface 261 and a second pressing surface 262 by itself.

[0067] In one embodiment, as Figures 1 - 4 shown (in combination with Figure 7 and Figure 8 ), the water spraying mechanism 2 includes a movable mounting seat 21 and a spray head 24 mounted on the mounting seat 21. The movable member 4 is connected to the mounting seat 21, so that the movable member 4 and the water spraying mechanism 2 can move together. Wherein, the mounting seat 21 is connected with a connecting pipe 26 having a water inlet passage. The connecting pipe 26 extends into the main water outlet cavity 112 of the valve structure 1 movably, so that the water in the main water outlet cavity 112 can be provided to the spray head 24 through the connecting pipe 26. One end of the connecting pipe 26 extending into the main water outlet cavity 112 has a first pressing surface 261 corresponding to the first pressure-receiving surface 121 and a second pressing surface 262 corresponding to the second pressure-receiving surface 131. The connecting pipe 26 is a pressing member for pressing the main valve core 12 and the pressure-relief valve core 13. When the movable member 4 is pressed, the connecting pipe 26 can move from the fifth position to the sixth position, and sequentially push the pressure-relief valve core 13 and the main valve core 12 during the process of moving from the fifth position to the sixth position, so that the main water path is opened; wherein, when the main water path is opened, the water in the main water outlet cavity enters the spray head 24 through the connecting pipe 26.

[0068] The movable member 4 can be arranged around the water spraying mechanism 2. In this way, after a container such as a cup to be cleaned is buckled on the movable member 4 and covers the nozzle 24 of the water spraying mechanism 2, pressing downwards can cause the movable member 4 to move downwards, thereby successively opening the pressure relief water passage and the main water passage of the valve structure 1.

[0069] In one example, the cup washer further includes a third spring 3. When releasing the movable member 4, the movable member 4, the mounting seat 21 and the connecting pipe 26 are reset under the elastic force of the third spring 3, and the main valve core 12 and the pressure relief valve core 13 are reset. That is, the movable member 4, the mounting seat 21 and the connecting pipe 26 move from the sixth position to the fifth position, the main valve core 12 is reset from the second position to the first position to disconnect the main water passage, and the pressure relief valve core 13 moves from the fourth position to the third position to disconnect the pressure relief water passage. Among them, the third spring 3 can be sleeved on the connecting pipe 26, with one end abutted against the mounting seat 21 and the other end abutted against the valve body 11.

[0070] In one embodiment, after the connecting pipe 26 is inserted into the main water outlet cavity 112 of the valve body 11, in order to prevent the connecting pipe 26 from coming out, a limiting structure 114 is arranged in the main water outlet cavity 112. The limiting structure 114 can be an annular structure arranged on the inner wall of the main water outlet cavity 112 or other forms of limiting blocks. The pressing end of the connecting pipe 26 having a first pressing surface 261 and a second pressing surface 262 is limited in the main water outlet cavity 112 through the limiting structure 114.

[0071] When installing the connecting pipe 26, the connecting pipe 26 can be first inserted from the main water inlet end of the valve body 11. When the connecting pipe 26 extends out from the direction of the limiting structure 114 towards the main water outlet end, the pressing end is limited on the side of the limiting structure 114 towards the main water inlet end, and then structures such as the main valve core 12 and the pressure relief valve core 13 are installed in the valve body 11. The end of the connecting pipe 26 far from the pressing end is then threadedly connected to the mounting seat.

[0072] To enable the water in the main water outlet cavity 112 to enter the connecting pipe 26 and be conveyed by the connecting pipe 26 to the nozzle 24, a first communication hole 263 communicating with the internal channel of the connecting pipe 26 is arranged at the pressing end of the connecting pipe 26, and a second communication hole 264 communicating with the inside and outside is arranged on the wall of the connecting pipe 26. The first communication hole 263 and the second communication hole 264 can be arranged one or more respectively. The water in the main water outlet cavity 112 can enter the internal channel of the connecting pipe 26 through the first communication hole 263 and the second communication hole 264, and then enter the nozzle mechanism 2 from the connecting pipe 26 for water spraying.

[0073] In one embodiment, as Figure 11 and Figure 12As shown, the water spraying mechanism 2 further includes a container 22 installed on the mounting base 21, an impeller 23 rotatably installed in the container 22, and a nozzle 24 connected to the impeller 23. The connecting pipe 26 communicates with the inside of the container 22. The water entering the container 22 can drive the impeller 23 to rotate, so that the impeller 23 drives the nozzle 24 to rotate. The rotating water spraying of the nozzle 24 is conducive to improving the cleaning effect.

[0074] As Figure 12 shown, the mounting base 21 includes a mounting cylinder 211 and a connecting cylinder 212 located at the lower end of the mounting cylinder 211. Among them, the container 22 is installed in the mounting cylinder 211, and the nozzle 24 is fixed to the impeller 23, specifically, it can be threadedly connected to the impeller 23. To prevent the impeller 23 and the container 22 from detaching from the mounting cylinder 211, an annular limiting member 25 can be provided. The annular limiting member 25 can be threadedly connected to the mounting cylinder 211 and stop at the upper ends of the impeller 23 and the container 22. The connecting portion 212 below the mounting base 21 is connected to the connecting pipe 26, and the connecting pipe 26 and the connecting portion 212 can be threadedly connected. The water in the connecting pipe 26 can enter the internal cavity of the connecting portion 212, and then enter the opening at the bottom end of the container 22. The water 22 in the container 22 enters the water spraying cavity 241 of the nozzle 24 to spray water, and the water flow in the container 22 drives the impeller 23 to rotate, and the impeller 23 drives the nozzle 24 to rotate and spray water.

[0075] In one embodiment, the cup washer further includes a base 5. As shown in FIGS. 1 and Figure 2 shown, the base 5 includes a bottom plate 51 having a central hole 511 and side walls 52 provided at the edge of the bottom plate 51. The side walls 52 and the bottom plate 51 form a groove with an upper opening; among them, the valve structure 1 is installed below the bottom plate 51, and the mounting base 21 is connected to the valve structure 1 through the central hole 511; the movable member 4 is arranged around the central hole 511 and installed in the groove. The outer edge of the movable member 4 cooperates with the side wall 52. Among them, the side wall 52 of the base 5 is provided with an opening to facilitate the water in the base 5 to flow out. The state of the movable member 4 installed in the base 5 is as Figure 1 shown. By setting the cooperation between the movable member 4 and the base 5, the appearance of the cup washer can be effectively improved.

[0076] In addition, to facilitate the installation of the cup washer, threads can be provided on the outer surface of the valve body 11, so that the valve body 11 is fixedly connected to a predetermined structure through the threads.

[0077] Next, according to Figures 3 - 8 describe the specific working process of using the cup washer to clean cups in one embodiment.

[0078] As Figure 3 and Figure 4As shown, the valve structure 1 is in the closed state, that is, the first valve core 12 is pressed against the first conical pipe section 113 under the elastic force of the first spring 16, and the second valve core 13 is pressed against the second conical pipe section 127 under the elastic force of the second spring 17. Both the pressure relief water path and the main water path are in the off state.

[0079] Press the movable part 4 downward. The movable part 4 drives the water spraying mechanism 2 and the connecting pipe 26 to move downward as a whole. The second pressing surface 262 of the connecting pipe 26 first contacts the second pressed surface 131 of the pressure relief valve core 13. When pushing the pressure relief valve core 13 to move downward from the third position to the fourth position, the second sealing ring 15 on the pressure relief valve core 13 leaves the second conical pipe section 127, and the pressure relief water path is opened.

[0080] As Figure 5 and Figure 6 shown, water enters from the main water inlet at the lower end of the valve body 11, first passes through the guiding hole 191 of the limiting ring 19, and enters the internal cavity 184 of the guiding column 18 from the first opening 181 of the guiding column 18, and then enters the pressure relief water inlet cavity 125 from the second opening 182. Since the pressure relief water path is opened, the water in the pressure relief water inlet cavity 125 flows to the pressure relief water outlet cavity 126 from the gap between the second sealing ring 15 and the second conical pipe section 127. At this time, the main water outlet cavity 126 is communicated with the main water inlet cavity 125. At this time, the water in the pressure relief water outlet cavity 126 and the water entering the main water outlet cavity 126 can enter the internal channel of the connecting pipe 26 through the first communication hole 263, then flow into the water spraying mechanism 2 from the connecting pipe 26, and be sprayed out from the nozzle 24.

[0081] The movable part 4 continues to move downward. The first pressing surface 261 of the connecting pipe 26 presses the first pressed surface 121 of the main valve core 12. The main valve core 12 moves downward from the first position to the second position, and the first sealing ring 14 on the main valve core 12 leaves the first conical pipe section 113, and the main water path is opened.

[0082] As Figure 7 and Figure 8 shown, the water entering the valve body 11 is divided into two paths. One path enters the pressure relief water inlet cavity 125 from the internal cavity 184 of the guiding column 18 through the second opening 182, and then flows out from the pressure relief water outlet cavity 126. The other path enters the main water inlet cavity 111 outside the guiding column 18 from the internal cavity 184 through the third opening 183, and then flows to the main water outlet cavity 112 from the gap between the first sealing ring 14 and the first conical pipe section 113. The water in the main water outlet cavity 112 enters the internal channel of the connecting pipe 26, and then flows to the nozzle 24 of the water spraying mechanism 2, thereby realizing water spraying.
