Description

Technical Field

[0001] This article relates to the field of kitchen and bathroom technology, and in particular to a valve structure and a cup washer. Background Technology

[0002] Existing cup washers (suitable for washing cups, but can also wash other containers) typically include a cleaning nozzle and a valve structure for supplying water to the cleaning nozzle. By pressing the container to be cleaned, the moving part of the control valve structure can be pushed, thereby opening the water passage of the valve structure to achieve cleaning. However, current cup washers require a relatively large amount of pressing force to open the water passage. Summary of the Invention

[0003] This application provides a valve structure and a cup washer to solve the problem that current cup washers require a large pressing force to open the water circuit.

[0004] An embodiment of this application provides a valve structure, including: a valve body and a sealing mechanism installed on the valve body;

[0005] The valve body is provided with an inlet chamber having a water inlet, an outlet chamber having a water outlet, and a pressure relief chamber having a pressure relief channel. The pressure relief chamber is connected to the inlet chamber, and the pressure relief channel can be operated to open and close.

[0006] The sealing mechanism includes a sealing element and a first spring, wherein the sealing element is configured to open and close the passage between the inlet chamber and the outlet chamber;

[0007] When the pressure relief channel is closed, the seal is pressed against the water inlet chamber and the water outlet chamber by the action of the first spring. When the pressure relief channel is opened, the seal moves toward the pressure relief chamber under the water pressure of the water inlet chamber, thereby opening the passage between the water inlet chamber and the water outlet chamber.

[0008] In one embodiment, the seal has a pressure relief chamber on one side and a backing portion on the other side. The backing portion is provided with a connecting port that connects the water inlet chamber and the water outlet chamber. When the seal abuts against the backing portion under the action of the first spring, it closes the connecting port. When the seal moves toward the pressure relief chamber under the water pressure of the water inlet chamber, it can leave the backing portion, thereby opening the connecting port.

[0009] In one embodiment, the valve body includes a valve body body and a valve seat fixed to the valve body body. The sealing element is a circular structure with a central sealing portion and an annular positioning portion. The central sealing portion is configured to correspond to the communication port. The first spring presses against the central sealing portion, and the annular positioning portion is limited between the valve body body and the valve seat.

[0010] In one embodiment, the seal is provided with an opening for connecting the water inlet chamber and the pressure relief chamber, the first spring is located in the pressure relief chamber, and one end of the first spring is provided with an insertion rod that is inserted into the opening.

[0011] An embodiment of this application also provides a cup washer, comprising: a mounting base, a water spraying mechanism, and a valve structure according to any one of claims 1-4, wherein the valve structure and the water spraying mechanism are mounted on the mounting base; wherein the water outlet of the water outlet chamber is connected to the water spraying mechanism.

[0012] In one embodiment, the cup washer further includes a pressure relief mechanism for opening and closing the pressure relief channel and a movable member that is movable relative to the mounting base. The movable member is configured to move between a first position and a second position. When the movable member is in the first position, the pressure relief mechanism is in a closed state of the pressure relief channel. When the movable member moves from the first position to the second position under the action of an external force, the pressure relief mechanism is triggered, and the pressure relief mechanism opens the pressure relief channel.

[0013] In one embodiment, the mounting base is provided with a pressure relief hole communicating with the pressure relief channel, and the pressure relief mechanism is configured to open and close the pressure relief channel by opening and closing the pressure relief hole.

[0014] In one embodiment, the mounting base is provided with a first docking hole and a second docking hole, the first docking hole being connected to the water inlet of the water spraying mechanism, and the second docking hole being connected to the pressure relief hole;

[0015] The valve structure is provided with a first connector having the water outlet and a second connector having the pressure relief channel. The first connector is connected to the first mating hole, and the second connector is connected to the second mating hole.

[0016] In one embodiment, the pressure relief mechanism includes a second spring and a pressure relief moving member installed in the pressure relief hole. The moving member is provided with a contact portion for contacting the pressure relief moving member. When the moving member is in the second position, the contact portion presses against the pressure relief moving member, and the pressure relief moving member moves to the position of opening the pressure relief hole under the pressure of the contact portion. When the moving member is in the first position, the pressure relief moving member moves to the position of closing the pressure relief hole under the action of the second spring.

[0017] In one embodiment, the movable element is mounted on the mounting base around the water spray mechanism so that it can be pressed when the container to be cleaned is fastened onto the water spray mechanism.

[0018] In one embodiment, one of the mounting base and the movable member is provided with a plurality of guide holes surrounding the water spray mechanism, and the other is provided with a plurality of guide posts respectively inserted into the guide holes. A third spring is provided in the guide hole to apply elastic force to the guide posts. The third spring is configured to reset the movable member when it is released.

[0019] In one embodiment, the system further includes a base fixed to the mounting seat. The base includes a bottom plate with a central hole and sidewalls disposed at the edges of the bottom plate. The sidewalls and the bottom plate form a groove with an opening at the top.

[0020] The mounting base is installed in the center hole, and the mounting base has an upper mounting end extending from the upper end of the center hole and a lower mounting end extending from the lower end of the center hole. The water spraying mechanism is installed on the upper mounting end, and the valve structure is installed on the lower mounting end.

[0021] The movable part is configured to surround the central hole and be installed in the groove, wherein the outer edge of the movable part mates with the sidewall.

[0022] In one embodiment, the water spraying mechanism includes a container mounted on the mounting base, an impeller rotatably mounted inside the container, and a nozzle connected to the impeller. The water outlet of the water outlet chamber is connected to the inside of the container, and the water entering the container can drive the impeller to rotate, thereby the impeller drives the nozzle to rotate.

[0023] In one embodiment, the lower end of the container is provided with a water inlet hole communicating with the internal cavity of the container and a water inlet groove arranged around the water inlet hole, and the water flowing out of the water outlet cavity can enter the water inlet hole and the water inlet groove;

[0024] The water inlet hole corresponds to the water spray chamber of the nozzle; multiple jet holes are provided on the wall between the water inlet tank and the internal cavity of the container. The multiple jet holes are arranged at intervals in the circumferential direction and are inclined in the same direction in the circumferential direction, so that the multiple inclined jet holes spray inclined water flow toward the impeller inside the container, thereby driving the impeller to rotate.

[0025] In the embodiments of this application, when the pressure relief channel is closed, the pressure in the pressure relief chamber and the inlet chamber are equal. The seal, under the action of the first spring, closes the passage between the inlet and outlet chambers. When the pressure relief channel is opened, the pressure relief chamber releases pressure, and the seal, under the pressure difference, overcomes the elastic force of the first spring and moves towards the pressure relief chamber, thus opening the passage between the inlet and outlet chambers. Since the pressure relief channel only needs to release pressure, opening and closing it is relatively easy, requiring only a small force. Therefore, the solution provided in this application controls the opening and closing of the water circuit by opening and closing the pressure relief channel, effectively overcoming the problem in the prior art where a large pressing force is required to open the water circuit for cleaning.

[0048] Embodiments of this application provide a valve structure, such as Figures 2-9 In the embodiment shown, the valve structure includes: a valve body 11 and a sealing mechanism 12 installed on the valve body 11;

[0049] The valve body 11 is provided with an inlet chamber 111 having an inlet 1111, an outlet chamber 112 having an outlet 1121, and a pressure relief chamber 113 having a pressure relief passage 1131. The pressure relief chamber 113 is connected to the inlet chamber 111, and the pressure relief passage 1131 can be operated to open and close.

[0050] The sealing mechanism 12 includes a seal 121 and a first spring 122. The seal 121 is configured to open and close the passage between the inlet chamber 111 and the outlet chamber 112.

[0051] When the pressure relief channel 1131 is closed, the seal 121 is pressed down by the first spring 122 to close the passage between the water inlet chamber 111 and the water outlet chamber 112. When the pressure relief channel 1131 is opened, the seal 121 moves toward the pressure relief chamber 113 under the water pressure of the water inlet chamber 111, thereby opening the passage between the water inlet chamber 111 and the water outlet chamber 112.

[0052] In the embodiments of this application, when the pressure relief channel 1131 is closed, the pressure in the pressure relief chamber 113 and the water inlet chamber 111 are equal. Under the elastic force of the first spring 122, the sealing member 121 abuts against the predetermined structure. At this time, the sealing member 121 closes the passage between the water inlet chamber 111 and the water outlet chamber 112. After the pressure relief channel 1131 is opened, the pressure relief chamber 113 is depressurized, and the pressure in the water inlet chamber 111 is greater than the pressure in the pressure relief chamber 113. Therefore, under the action of the pressure difference, the sealing member 121 overcomes the elastic force of the first spring 122 and moves towards the pressure relief chamber 113, opening the passage between the water inlet chamber 111 and the water outlet chamber 112. Since the pressure relief channel 1131 only needs to relieve pressure, opening and closing the pressure relief channel 1131 is relatively easy, requiring only a small force. The valve structure provided in this application can be used in a cup washer. Using this valve structure in a cup washer allows for easier control of the water flow opening and closing, effectively overcoming the problem in existing technologies where significant pressure is required to open the water flow. It is understood that the valve structure provided in this application is not limited to cup washers; it can be used in other devices that require a labor-saving method to open the water flow.

[0053] In one embodiment of this application, such as Figure 8 and Figure 9 As shown, the seal 121 has a pressure relief chamber 113 on one side and a stop portion 114 on the other side. The stop portion 114 is provided with a connecting port 1141 that connects the water inlet chamber 111 and the water outlet chamber 112. When the seal 121 abuts against the stop portion 114 under the action of the first spring 112, it closes the connecting port 1141. When the seal 121 moves toward the pressure relief chamber 113 under the action of the water pressure in the water inlet chamber 111, it can leave the stop portion 114, thereby opening the connecting port 1141.

[0054] To facilitate the installation of the sealing element 121 and the first spring 122, the valve body 11 can be configured to include a valve body main body 11a and a valve seat 11b. The valve seat 11b is fixed to the valve body main body 11a. The sealing element 121 is a circular structure with a central sealing part 1211 and an annular positioning part 1212. The central sealing part 1211 is configured to correspond to the communication port 1141. The first spring 122 pushes against the central sealing part 1211 in the direction of the abutment part 114, so that the central sealing part 1211 can block the communication port 1141.

[0055] refer to Figure 8The valve body 11a has an inlet chamber 111 open on one side. An abutment portion 114 with a connecting port 1141 is provided within the inlet chamber 111. An outlet chamber 112, connecting to the outlet 1121, is formed inside the abutment portion 114. Additionally, to limit the annular positioning portion 1212 of the seal 12, the valve body 11a is provided with a first annular groove 115 surrounding the inlet chamber 111, and the valve seat 11b is provided with a second annular groove 116 surrounding the pressure relief chamber 113 (see reference). Figure 9 After the valve seat 11b is fixed to the valve body 11a, the two sides of the annular positioning part 1212 of the sealing member 121 are respectively embedded in the first annular groove 115 and the second annular groove 116, and the first spring 122 is located in the pressure relief chamber 113. One end of the first spring 122 abuts against the central sealing part 1211 of the sealing member 121, applying pressure to the central sealing part 1211 toward the abutment part 114, and the other end abuts against the valve seat 11b. Spring seats that position the two ends of the first spring 122 can be provided on the valve seat 11b and the sealing member 12 to ensure the stability of the first spring 122.

[0056] In one example, the seal 121 is provided with an opening 1213 for connecting the water inlet chamber 111 and the pressure relief chamber 113, the first spring 122 is located in the pressure relief chamber 113, and one end of the first spring 122 is provided with an insertion rod 1221 inserted into the opening 1213.

[0057] By inserting the insertion rod 1221 of the first spring 122 into the opening 1213 of the seal 121, the seal 121 can be prevented from rotating to a position where it cannot connect the water inlet chamber 111 and the pressure relief chamber 113 (for example, rotating to the position of the abutment part 114, where the abutment part 114 blocks the opening 1213). Moreover, by inserting the insertion rod 1221 into the opening 1213, it can play a role in preventing blockage. During the opening and closing of the pressure relief channel 1311, the first spring 122 will contract and extend, thereby driving the insertion rod 1221 to move. The insertion rod 1221 moves in the opening 1213, which has the function of clearing the opening 1213 and effectively preventing the opening 1213 from being blocked by scale or other impurities.

[0058] It is understood that the structure of the valve body 11 and the arrangement of the inlet chamber 111, the outlet chamber 112 and the pressure relief chamber 113 on the valve body 11 are not limited to... Figure 8 and Figure 9 The form shown can have many variations, which are not limited here.

[0059] An embodiment of this application also provides a cup washer, including: a mounting base 4, a water spraying mechanism 2, and a valve structure 1 as described above. The valve structure 1 and the water spraying mechanism 2 are mounted on the mounting base 4. The water spraying mechanism 2 has a water inlet passage communicating with the water outlet 1121 of the water outlet chamber 112. When the pressure relief valve passage 1131 of the valve structure 1 is opened, the seal 121 opens the communication between the water inlet chamber 111 and the water outlet chamber 112. Water from the water inlet chamber 111 enters the water outlet chamber 112, and water from the water outlet chamber 112 enters the water spraying mechanism 2, thereby allowing the water spraying mechanism 2 to spray water to clean the container.

[0060] In one embodiment, the cup washer further includes a pressure relief mechanism 3 for opening and closing the pressure relief channel 1131 and a movable member 5 that is movable relative to the mounting base 4. The movable member 5 is configured to move between a first position and a second position. When the movable member 5 is in the first position, the pressure relief mechanism 3 is in the state of closing the pressure relief channel 1131. When the movable member 5 moves from the first position to the second position under the action of an external force, the pressure relief mechanism 3 is triggered, and the pressure relief mechanism 3 opens the pressure relief channel 1131.

[0061] exist Figures 1-7 In this example, the mounting base 4 is provided with a pressure relief hole 451 communicating with the pressure relief channel 1131. The pressure relief mechanism 3 is installed in the pressure relief hole 451 and is configured to open and close the pressure relief hole 451. The pressure relief mechanism 3 opens and closes the pressure relief channel 1131 by opening and closing the pressure relief hole 451. In this example, providing a pressure relief hole 451 on the mounting base 4 makes it easy for the movable part 5 to contact the pressure relief mechanism 3 to open the pressure relief hole 451 when it moves relative to the mounting base 4.

[0062] In one example, the water spray mechanism 2 is mounted on the upper part of the mounting base 4, and the valve structure 1 is mounted on the lower first docking hole 41 and the second docking hole 42.

[0063] The installation of mounting base 4 and valve structure 1 is as follows: Figures 3-5 As shown, the mounting base 4 is provided with a first mating hole 41 and a second mating hole 42. The first mating hole 41 is connected to the water inlet of the water spray mechanism 2, and the second mating hole 42 is connected to the pressure relief hole 451; combined with Figure 8 and Figure 9 The valve structure 1 is provided with a first connector 1122 having a water outlet 1121 and a second connector 1132 having a pressure relief channel 1131. The first connector 1122 is connected to the first mating hole 41, and the second connector 1132 is connected to the second mating hole 42. In this way, water from the water outlet chamber 112 can enter the first mating hole 41 through the first connector 1122, thereby entering the water inlet of the water spray mechanism 2. The pressure relief channel 1131 can communicate with the pressure relief hole 451 through the second connector 1132 to relieve pressure through the pressure relief hole 451.

[0064] exist Figure 5 In the example, the pressure relief mechanism 3 includes a second spring 32 and a pressure relief moving member 31 installed in the pressure relief hole 451. The movable member 5 is provided with a contact portion 52 for contacting the pressure relief moving member 31. When the movable member 5 is in the second position, the contact portion 52 presses against the pressure relief moving member 31, and the pressure relief moving member 31 moves to the position of opening the pressure relief hole 451 under the pressure of the contact portion 52. When the movable member 5 is in the first position, the pressure relief moving member 31 moves to the position of closing the pressure relief hole 451 under the action of the second spring 32.

[0065] To ensure that the pressure relief movable component 31 and the second spring 32 are installed in and confined within the pressure relief hole 451, the pressure relief mechanism 3 further includes a limiting connector 34 with an opening. After the pressure relief movable component 31 and the second spring 32 are installed in the pressure relief hole 451, the limiting connector 34 is connected to the pressure relief connector 45 with the pressure relief hole 451. One end of the pressure relief movable component 31 extends out of the opening of the limiting connector 34, allowing the contact portion 52 of the movable component 5 to contact the pressure relief movable component 31. The pressure relief connector 45 may have an external thread, and the limiting connector 34 may have an internal thread. The limiting connector 34 is bolted to the pressure relief connector 45. To prevent water leakage between the limiting connector 34 and the pressure relief connector 45, a sealing component 35 may be provided between the limiting connector 34 and the pressure relief connector 45.

[0066] In addition, a sealing ring 33 is fitted on the pressure relief moving part 31. Under the action of the second spring 32, the sealing ring 33 abuts against the abutment surface provided on the inner side of the limiting connector 34, thereby sealing the pressure relief hole 451. When the contact part 52 of the movable part 5 squeezes the pressure relief moving part 31, the pressure relief moving part 31 moves toward the pressure relief hole 451, forming a water outlet gap between the pressure relief moving part 31 and the pressure relief hole 451, thereby opening the pressure relief hole 451.

[0067] It can be understood that the pressure relief hole 451 and the pressure relief mechanism 3 are not limited to the arrangement described above. For example, the pressure relief hole 451 and the pressure relief mechanism 3 can also be arranged on the valve structure 1, that is, installed at the outlet end of the pressure relief channel 1131. The structure of the mounting base 4 and the movable part 5 can be adapted so that the movement of the movable part 5 can contact the pressure relief mechanism 3.

[0068] In one example, the movable member 5 is mounted on the mounting base 4 around the water spray mechanism 2 so that it can be pressed when the container to be cleaned is fastened onto the water spray mechanism 2. In practice, the container to be cleaned (e.g., a cup) is fastened onto the nozzle of the water spray mechanism 2 and the cup is pressed down. The movable member 5 moves downward, and when it moves to a second position, it squeezes the pressure relief movable member 31 of the pressure relief mechanism 3, which opens the pressure relief hole 451.

[0069] To ensure that the movable part 5 can move stably and reset when it is released, one of the mounting base 4 and the movable part 5 is provided with multiple guide holes 46 surrounding the water spray mechanism 2, and the other is provided with multiple guide posts 53 respectively inserted into the guide holes 46. A third spring 47 is provided in the guide hole 46 to apply elastic force to the guide post 53. The third spring 47 is configured to reset the movable part 5 when it is released.

[0070] Figure 10 An example of a mounting base 4 is shown. The mounting base 4 includes a mounting base 43, a mounting cylinder 44 disposed on the mounting base 43, and a plurality of columns with guide holes 46 arranged around the mounting cylinder 44, which is configured to mount the water spray mechanism 2.

[0071] Figure 11 An embodiment of the movable element 5 is shown. The movable element 5 includes a disc 51 and a plurality of guide posts 53 disposed on the lower surface of the disc 51 around a central hole (the central hole is used to avoid the nozzle of the water spraying mechanism 2).

[0072] like Figure 12 As shown, a water spraying mechanism 2 is installed inside the mounting cylinder 44 of the mounting base 4. When the movable part 5 is mounted on the mounting base 4 with its lower surface facing the mounting base 4, the nozzle 21 of the water spraying mechanism 2 corresponds to the center hole of the movable part 5, and the guide post 53 is inserted into the guide hole 46 one by one.

[0073] In one embodiment, the cup washer may further include a base 6 fixed to the mounting seat 4. The base 6 includes a bottom plate 61 with a central hole 611 and a side wall 62 disposed at the edge of the bottom plate 61. The side wall 62 and the bottom plate 61 form a groove with an opening at the top. A notch may be provided on one side wall of the groove so that water in the groove can flow out through the notch. The mounting seat 4 is mounted on the central hole 611. The mounting seat 4 has an upper mounting end extending above the central hole 611 and a lower mounting end extending below the central hole. The water spray mechanism 2 is mounted on the upper mounting end, and the valve structure 1 is mounted on the lower mounting end.

[0074] The movable component 5 is positioned around the central hole 611 and within the groove of the base 6, wherein the outer edge of the movable component 5 mates with the side wall 62. The movable component 5, the water spray mechanism 2, and the base 6 are arranged as follows: Figure 1 As shown, by setting the movable part 5 to cooperate with the groove of the base 6, the appearance of the product can be improved.

[0075] Furthermore, by setting the outline of the groove and the movable part 5 to be approximately square, the movable part 5 can mate with the mounting base 4 when installed in the groove in any of the four directions. For example... Figure 11As shown, the lower surface of the disc body 51 of the movable part 5 is provided with four contact parts 52 and four guide posts 53 surrounding the central hole. As long as the four sides of the movable part 5 mate with the four sides of the groove, one of the four contact parts 52 can correspond to the pressure relief mechanism 3, and the guide posts 53 can be inserted into the guide hole 46. There is no need to align the movable part 5 with the guide hole 46 or the pressure relief mechanism 3 below. Therefore, the installation of the movable part 5 is relatively convenient.

[0076] In one embodiment, the water spraying mechanism 2 includes a container mounted on the mounting base 4, an impeller 22 rotatably mounted inside the container 23, and a nozzle 21 connected to the impeller 22. The outlet 1121 of the water outlet chamber 112 is connected to the container 23. Water entering the container 23 can drive the impeller 22 to rotate, thereby causing the impeller 22 to drive the nozzle 21 to rotate. In this way, when the valve structure 1 supplies water to the nozzle mechanism 2, the nozzle 21 rotates and sprays water, which helps to improve the cleaning effect.

[0077] like Figure 5 and Figure 13 As shown, an upwardly extending mounting cylinder 44 is provided at the center of the mounting base 4. The container 23 is installed inside the mounting cylinder 44, and an impeller 22 is installed inside the container 23. To prevent the impeller 22 and the container 23 from coming out of the mounting cylinder 44, a limiting ring 24 can be installed on the mounting cylinder 44. The outer surface of the limiting ring and the mounting cylinder 44 can be configured to be threaded together. The limiting ring stops the top surface of the impeller 22 and the container 23. The lower end of the nozzle 21 passes downward through the limiting ring 24 and is installed in the center hole of the impeller 22. The lower end of the nozzle 21 can be threaded together with the impeller 22.

[0078] like Figure 13 and Figure 15As shown, the lower end of the container 23 is provided with a water inlet hole 231 communicating with the internal cavity of the container 23 and a water inlet groove 232 arranged around the water inlet hole 231. Water flowing out of the outlet cavity 112 of the valve structure 1 can enter the water inlet hole 231 and the water inlet groove 232. The water inlet hole 231 corresponds to the spray cavity 211 of the nozzle 21. Water entering from the water inlet hole 231 flows to the spray cavity 211 and is sprayed out. The water inlet groove 232 can be an arc-shaped groove around the water inlet hole 231 or an annular groove around the water inlet hole 231. Multiple jet holes 233 are provided on the wall between the water inlet groove 232 and the internal cavity of the container 23. The multiple jet holes 233 are arranged at intervals in the circumferential direction and are inclined in the same direction in the circumferential direction. Thus, the multiple inclined jet holes 233 spray inclined water flow toward the impeller 22 inside the container 233, driving the impeller 22 to rotate. In addition, in order to allow the water flowing out of the outlet chamber 112 to enter the inlet hole 231 and the inlet groove 232, the inlet hole 231 and the inlet groove 232 are configured to communicate with the first docking hole 41 of the mounting base 4, so that when the first connector 1122 of the valve structure 1 is connected to the first docking hole 41, the water in the outlet chamber 112 of the valve structure 1 can enter the inlet hole 231 and the inlet groove 232.

[0079] like Figures 13-15 As shown, the nozzle 21 is provided with a plurality of water spray holes 212 that communicate with the water spray chamber 211. The plurality of water spray holes 212 include a water spray hole located at the center and a plurality of water spray holes arranged circumferentially around the center. The plurality of water spray holes arranged circumferentially can be inclined to form a spiral water spray pattern.

[0080] It is understandable that the water spraying mechanism 2 can have various structural forms, such as the nozzle 21 being set to not rotate.

[0081] The following is based on Figure 1-7 The structure shown describes the specific process of cleaning a container using a cup washer in one embodiment.

[0082] The cup to be cleaned is fastened onto the nozzle 21 of the water spraying mechanism 1, and the cup is pressed down. Under the pressure of the cup, the movable part 5 moves from the first position to the second position. In the second position, the contact part 52 of the movable part 5 squeezes the pressure relief moving part 31 of the pressure relief mechanism 3. The pressure relief moving part 31 moves toward the pressure relief hole 451, thereby opening the pressure relief hole 451 and releasing the pressure in the pressure relief chamber 113.

[0083] Since the inlet chamber 111 receives water from the inlet port 1111, when the pressure relief chamber 113 is depressurized, the pressure inside the inlet chamber 111 will be greater than the pressure in the pressure relief chamber 113. This pressure will then push the seal 121 towards the pressure relief chamber 113, opening the connection port 1141 between the inlet chamber 111 and the outlet chamber 112. Water from the inlet chamber 111 then flows into the outlet chamber 112 through the inlet port 1141. Figure 3 and Figure 6 The status of the seal 121 blocking the communication port 1141 is shown. Figure 4 and Figure 7 The state of the seal 121 with the communication port 1141 open is shown.

[0084] Water from the outlet chamber 112 enters the inlet hole 231 and inlet tank 232 of the container 23 of the spray mechanism 2. Water from the inlet tank 232 is sprayed onto the impeller 22 through the jet hole 233, which drives the impeller 22 to rotate. The impeller 22 drives the nozzle 21 to rotate. Water from the inlet hole 231 enters the spray chamber 211 of the nozzle 21, thereby causing the nozzle 21 to rotate and spray water.

[0085] After the cup is cleaned and removed, the movable part 5 is released and returns to the first position from the second position. The pressure relief mechanism 3 closes the pressure relief hole 451, the pressure relief chamber 113 is closed, and the pressure in the pressure relief chamber 113 and the water inlet chamber 111 gradually become equal. Under the action of the first spring 122, the sealing part 121 blocks the connecting port 1141, the passage between the water inlet chamber 111 and the water outlet chamber 112 is closed, the water supply to the nozzle 21 is cut off, and the nozzle 21 stops spraying water.
