[0003] This application claims priority to Chinese patent application No. 2025205416962, filed on March 26, 2025, entitled "A Cup Washer", the entire contents of which are incorporated herein by reference. Technical Field

[0004] This application relates to the field of cup washing technology, and in particular to a cup washing device. Background Technology

[0005] Cup washer is suitable for cleaning water cups, tea cups, baby bottles, and various beverage cups. It is especially effective at cleaning small-mouthed cups that are difficult to reach with a cloth. However, the drain tray is fixed to the countertop, and the small gap between its bottom and the countertop makes it difficult to clean, leading to dirt accumulation and bacterial growth, causing significant inconvenience to users. Furthermore, most cup washers on the market have the following drawbacks: 1. The washing components include a cup holder and a drain tray. The cup holder controls the water flow, holds the cups, and drains the water, while the drain tray primarily drains and guides water. The drain tray is not removable, making it difficult to clean. 2. The fixed water outlet angle of the nozzle limits the cleaning area and fails to achieve the desired cleaning effect. 3. When the water spray is turned on, the cup is pressed down on the cup holder, and the cup, cup holder, and nozzle move down simultaneously, while the drain tray remains relatively stationary. This means that the depth to which the nozzle penetrates the cup remains constant. When cleaning a deeper cup, the bottom may not be cleaned effectively due to insufficient water flow or other reasons. This makes it difficult to clean the bottom of a deeper cup properly, resulting in areas that are not thoroughly cleaned. Summary of the Invention

Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] Referring to Figures 1 to 6, a cup washer includes a base 10, a water channel assembly, a nozzle assembly, and a drain tray 40. The base is fixedly assembled to a mounting platform 100 and may be a copper pipe that can be fixed to the mounting platform. The water channel assembly is disposed within the base and has a channel for fluid to pass through. The channel may include an inlet channel 53 and an outlet channel 55, and the channel is provided with at least one valve port for controlling the opening and closing of the channel. The nozzle assembly is configured to communicate with the outlet end of the water channel assembly, and water can be ejected from the spray port 21 of the nozzle assembly to clean the cup. The drain tray 40 is detachably assembled to the base, the water channel assembly, or both, wherein the drain tray is configured to be movable to control the opening and closing of the valve port.

[0046] With the aforementioned cup washer, the drain tray can be detachably assembled onto the base, the water channel assembly, or both, facilitating the installation and removal of the drain tray, thus making it easier to clean the drain tray and the surface of the mounting platform covered by the drain tray.

[0047] Referring to Figure 6, in some embodiments, the valve port may be formed by the inner circumference of the convex ring 33. The cup washer also includes a sealing ring 57, which is disposed on the outer circumference of the water channel assembly. The sealing ring 57 can cooperate with the valve port, and whether or not the sealing ring 57 cooperates with the convex ring determines whether water flows through the channel.

[0048] In some embodiments, the drain tray is detachably fitted around the nozzle assembly, allowing for quick installation or removal of the drain tray, which can be easily removed without the need for tools, simply by fitting it around the nozzle assembly.

[0049] Referring to Figures 3, 5, and 6, the cup washer also includes a movable valve shaft 30, which is sleeved on the outer periphery of the nozzle assembly. In this way, the drain tray is sleeved on the outer periphery of the movable valve shaft, and the drain tray can move up and down relative to the nozzle assembly, so it can be directly removed from the whole assembly.

[0050] In some embodiments, the cup washer also includes a first sealing ring 42 disposed between the movable valve shaft 30 and the drain pan. The first sealing ring 42 can reduce water flow between the drain pan and the movable valve shaft, thereby reducing the accumulation of dirt and bacteria.

[0051] In some embodiments, the drain tray is provided with a perforation 44, the size of which is larger than the outer diameter of the nozzle assembly and the movable valve shaft, so as to facilitate the installation and removal of the drain tray.

[0052] In some embodiments, an annular boss 14 is formed on the base, the outer diameter of which is adapted to the major diameter of the movable valve shaft, and at least a portion of the annular boss 14 passes through a hole in the drain pan, such that the hole is located on the outer periphery of the movable valve shaft and the annular boss.

[0053] In some embodiments, the drain plate has a mounting hole 45 in the middle of its main body. The mounting hole 45 is coaxially connected with the through hole 44. The diameter of the mounting hole can be smaller than that of the through hole, thus forming an abutment part 41. The mounting hole is configured to form a hole-axis mating relationship with the water channel assembly. The drain plate is configured to be able to move along the axial direction of the water channel assembly to achieve fitting on or off the water channel assembly.

[0054] In some embodiments, the cup washer further includes a pressure plate 60, the lower end of which abuts against a drain pan. A movable valve shaft is operatively connected to the drain pan, and the drain pan is configured to control the movable valve shaft to move axially, circumferentially, or simultaneously along the waterway assembly to switch the movable valve shaft between a closed valve port and an open valve port. The movable valve shaft can be controlled by the drain pan, the pressure plate, or both the drain pan and the pressure plate to perform corresponding movements.

[0055] In some embodiments, the water channel assembly can be fixed to the inner circumference of the base. The water channel assembly mainly controls whether water flows through, thereby cleaning the item to be cleaned (such as a cup). A nozzle assembly with a spray nozzle 21 can be connected to the water outlet of the water channel assembly. When water flows through the water channel assembly, water is ejected from the spray nozzle of the nozzle assembly to clean the cup. A movable valve shaft 30 can be sleeved on the outer circumference of the water channel assembly. The movable valve shaft can move axially relative to the water channel assembly (up and down in the figure) to realize the opening or closing of the water channel assembly's water flow function. A drain plate can be connected to the movable valve shaft. When the drain plate is pressed, it can drive the movable valve shaft to move axially relative to the water channel assembly. The nozzle assembly can be placed above the drain plate.

[0056] In some embodiments, a reset spring 31 is also included. The reset spring can be connected to the movable valve shaft so that the movable valve shaft can be moved and then reset, thereby switching the water passage function of the water passage assembly from open to closed. One end of the reset spring acts on the movable valve shaft, and the other end can be connected to the base.

[0057] Under normal conditions, the movable valve shaft, under the action of the return spring, achieves a sealing fit between the convex ring and the sealing ring, preventing water flow and keeping the water channel assembly in a non-water-flowing state. When cleaning is required, the cup moves the drain plate downwards, at which point the return spring is compressed, and the movable valve shaft and the cup move downwards relative to the nozzle assembly, base, etc., so that the nozzle assembly is located deeper in the cup. At the same time, the convex ring and the sealing ring separate, allowing water to flow through the water channel assembly. Water flows from the spray nozzle onto the inner circumference of the cup for cleaning. After cleaning, the cup is removed, and under the action of the return spring, the drain plate and the movable valve shaft reset, and the water channel assembly returns to the non-water-flowing state.

[0058] In some embodiments, a water passage 32 is formed between the outer periphery of the water channel assembly and the inner periphery of the movable valve shaft. The water channel assembly mainly includes an inlet channel 53, an outlet 54, an inlet 56, and an outlet channel 55. The water channel assembly includes an inlet shaft 51 and an outlet shaft 52 that can be connected. The inlet shaft and the outlet shaft can be manufactured as a single unit or configured as separate units, forming a component through a threaded connection. The separate connection method facilitates the assembly of the entire product. The inlet channel 53 and the outlet 54 are disposed on the inlet shaft and maintain water flow. The outlet channel 55 and the inlet 56 are disposed on the outlet shaft and maintain water flow. The water flows sequentially through the inlet channel, the outlet, the water passage, the inlet, and the outlet channel before flowing to the nozzle assembly.

[0059] When the movable valve shaft is in the sealed position relative to the base, the water passage is in a water-cut-off state; when the movable valve shaft is in the unsealed position, the water passage is in a water-flow state.

[0060] In some embodiments, the water passage assembly located at the water passage is provided with a sealing ring 57 on its outer periphery and a convex ring 33 on its inner periphery of the movable valve shaft. When the movable valve shaft is in the sealed position, the convex ring can seal with the sealing ring, that is, when the movable valve shaft is in the sealed position, the water passage is in a water-cut-off state. At the same time, the water inlet shaft can be connected to the water source. Referring to the attached drawings, the water source flows from the inside of the water inlet shaft to the outside water passage, flows to the inner periphery of the water outlet shaft, and is ejected from the spray nozzle.

[0061] To prevent water leakage, a first seal 58 is provided between the outer circumference of the inlet shaft below the outlet and the inner circumference of the movable valve shaft, and a second seal 59 is provided between the outer circumference of the outlet shaft above the inlet and the inner circumference of the movable valve shaft. Both seals maintain a sealed fit even when the movable valve shaft moves relative to the water channel assembly.

[0062] In some embodiments, the lower end of the water inlet shaft can be fixedly connected to the inner circumference of the base, and the upper end of the water outlet shaft is connected to a nozzle assembly, which can be connected by a thread. This ensures that the water channel assembly and the nozzle assembly are fixed on the base during use and will not move axially.

[0063] In some embodiments, the nozzle assembly includes a mating nozzle 22, a connector 23, and a bearing 24. The bearing is fixed to the upper end of the water outlet shaft, i.e., the water outlet end of the water outlet shaft, by a locking nut 25, which facilitates the rotation of the nozzle. The inner circumference of the connector is mated with the outer circumference of the bearing, and the outer circumference of the connector is connected to the nozzle. The nozzle is provided with a non-axially oriented spray port 21, which allows the nozzle to rotate relative to the base under the action of water impact force, increasing the cleaning area.

[0064] In some embodiments, the drain pan can be sleeved on the outer periphery of the movable valve shaft. The drain pan is provided with an abutment portion 41, which is located at the upper end of the through hole and protrudes inward. The abutment portion can abut and cooperate with the upper end of the movable valve shaft so that the drain pan and the movable valve shaft can move axially downward synchronously. A first sealing ring 42 is also provided between the outer periphery of the movable valve shaft and the drain pan to prevent water leakage between the two.

[0065] In some embodiments, the pressure plate can be located on the outer periphery of the nozzle assembly, and the lower end of the pressure plate can abut against the drain pan, the movable valve shaft, or both the drain pan and the movable valve shaft, so that the pressure plate can drive the movable valve shaft to move axially downward. The pressure plate can be an optional accessory that can support the cup for downward pressure and can also be called a cup holder, but it will only drive the movable valve shaft to move downward, and the nozzle assembly will not move.

[0066] In some embodiments, an annular flange 11 is also provided on the outer periphery of the base. The lower end face of the annular flange can be supported on the mounting platform. A second sealing ring 12 is provided on the mounting platform and the lower end face of the annular flange to prevent water from leaking from the mounting hole of the mounting platform to the bottom of the platform.

[0067] In some embodiments, the drain pan can move vertically up and down, serving as a switch to turn the water on and off, controlling the downward movement of the movable valve shaft. One end of the movable valve shaft abuts against a return spring, and the other end is connected to the drain pan, which has a built-in water channel assembly. When an external force is applied, the drain pan moves vertically downward, separating the seal between the movable valve shaft and the water channel assembly, and water flows out of the nozzle. After the external force is released, the movable valve shaft returns to its original position under the elastic action of the return spring.

[0068] The water channel assembly includes an outlet shaft and an inlet shaft, one end connected to the nozzle assembly and the other end connected to the water source; it is also fixedly connected to the base. The nozzle assembly is mounted on the outlet shaft with nuts and secured longitudinally by locking nuts. The nozzle assembly includes nozzles that can rotate relative to the outlet assembly. The nozzles have non-directional spray nozzles distributed at their tops, which rotate automatically under the force of water flow. Bearings can also be added to make the nozzle rotation smoother.

[0069] The drain tray can function as a water on / off switch. It can be a standalone bowl shape or equipped with a pressure plate. When not equipped with a pressure plate, the drain tray has an irregular shape with raised and recessed areas for holding water for washing cups.

[0070] In some embodiments, a circumferential movement range limiting fitting part is provided below the drain pan or inside the hole, which cooperates with the fitting part to limit the range or positioning of the circumferential movement. This can be a protrusion 13 on the base, and an arc-shaped groove 43 at the lower end of the drain pan that mates with the protrusion. The base is a copper tube with external threads, which is fixed to the mounting platform. The fixing in this application is basically axial fixing, meaning that after installation, there is basically no axial movement.

[0071] Referring to Figures 1 to 6, in some embodiments, a base is fixedly mounted on a mounting platform 100. This base can be a copper pipe that can be fixed on the mounting platform. The water channel assembly has a water flow function and can be fixed to the inner circumference of the base. The water channel assembly mainly determines whether water flows through, thereby cleaning the cleaning items (such as cups). A nozzle assembly with a spray nozzle 21 can be connected to the water outlet of the water channel assembly. When water flows through the water channel assembly, water is ejected from the spray nozzle of the nozzle assembly to clean the cup. A movable valve shaft can be sleeved on the outer circumference of the water channel assembly and can move axially relative to the water channel assembly (up and down in the figure) to open or close the water flow function of the water channel assembly. A drain plate can be connected to the movable valve shaft. When the drain plate is pressed, it can drive the movable valve shaft to move axially relative to the water channel assembly. The nozzle assembly can be placed above the drain plate.

[0072] Under normal conditions, the movable valve shaft, under the action of the return spring, achieves a sealing fit between the convex ring and the sealing ring, preventing water flow and keeping the water channel assembly in a non-water-flowing state. When cleaning is required, the cup moves the drain plate downwards, at which point the return spring is compressed, and the movable valve shaft and the cup move downwards relative to the nozzle assembly, base, etc., so that the nozzle assembly is located deeper in the cup. At the same time, the convex ring and the sealing ring separate, allowing water to flow through the water channel assembly. Water flows from the spray nozzle onto the inner circumference of the cup for cleaning. After cleaning, the cup is removed, and under the action of the return spring, the drain plate and the movable valve shaft reset, and the water channel assembly returns to the non-water-flowing state.

[0073] Meanwhile, the drain plate 40 can be detachably assembled onto the base, water channel assembly, or simultaneously onto the base and water channel assembly. The drain plate is configured to be movable to control the opening and closing of the valve port. In other words, the drain plate can be detachably fitted onto the outer periphery of the nozzle assembly. This allows for quick installation or removal of the drain plate, as it can be easily removed without the need for tools, simply by fitting it onto the outer periphery of the nozzle assembly.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
