Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] 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 the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] Referring to the drawings in the specification, a self-rotating cup washer comprises a base 10 having a water outlet 11, and a nozzle 20. The nozzle is provided with at least one eccentric water outlet 21, where the eccentricity is relative to an axis C. Alternatively, a jet outlet 22 coaxial with the nozzle's rotation axis may be provided. Water from the water outlet is ejected through the outlet to clean the cup. The nozzle may be located peripherally of the water outlet. In one embodiment, the nozzle is attached to the periphery of the water outlet. Water ejected from the outlet drives the nozzle to rotate relative to the base. When the water from the outlet strikes the inner circumferential wall of the nozzle, it is discharged through a water outlet eccentrically located from the outlet. This drives the nozzle to rotate relative to the base. The eccentric water outlet forms a circumferential water flow that cleans the inner circumferential wall of the body, achieving full coverage. Simply attaching the body to the periphery of the nozzle provides a simple, single, and effortless cleaning action. Furthermore, the impact force of water is utilized, eliminating the need for external energy sources such as electricity.

[0031] Preferably, the nozzle is sleeved on the outer periphery of the water outlet, and the nozzle can be coaxially arranged with the water outlet. Specifically, the axis of rotation of the nozzle and the axis of the water outlet can be coaxially arranged, and the water outlet is not coaxially arranged with the water outlet, so that the water flow ejected from the water outlet can drive the nozzle to rotate.

[0032] Furthermore, the nozzle includes a semi-spherical portion, which means that the water inlet and outlet of the water outlet are both on the inner and outer surfaces of the semi-spherical portion, and both the inner and outer surfaces are spherical. The water outlet is arranged on the semi-spherical portion, and the water outlet can be staggered with the water outlet. The shape of the water outlet can be one or a combination of two or more of circular, square, and strip shapes, preferably a strip shape, which can discharge water from the blade and better clean the inner wall of the cup body. Referring to the drawings of the specification, when the water outlet is in a strip shape, its mouth can exceed the center point of the semi-spherical portion, that is, the axis C of the semi-spherical portion can rotate around the axis C under the action of water pressure. The strip-shaped water outlet can form a surface D of a water curtain, and the position of the axis C projected on the surface D is within the water outlet, or the vertical point E from the axis C to the surface D is within the water outlet, so that the top of the cup can be cleaned more comprehensively.

[0033] Furthermore, a rotating seat 30 is provided on the outer periphery of the base located on the side of the water outlet, and the rotating seat can rotate relative to the base. The nozzle can be connected to the rotating seat. During use, the rotating seat is driven to rotate synchronously by the rotation of the nozzle. A fixed seat 40 is also provided on the outer periphery of the base located on the side of the water outlet. A ball 41 is provided between the fixed seat and the rotating seat. The ball can better enable the rotating seat and the nozzle to rotate relative to the base. The fixed seat can restrict the nozzle and the rotating seat to the base and only rotate, that is, the water flow will not flush (detach) the nozzle from the base.

[0034] Preferably, a first step surface 31 is provided on the inner periphery of the rotating seat, and the ball is arranged between the first step surface and the lower end surface of the fixed seat. The fixed seat can be located on the inner periphery of the rotating seat, and an opening 42 that can be adapted to the water outlet is provided on the fixed seat to ensure the outflow of water.

[0035] In one embodiment, the fixed seat can be screwed to the base, and the nozzle can be screwed to the rotating seat, so that the nozzle can be rotated relative to the water outlet. A second step surface 43 is also provided on the fixed seat, and the second step surface can be abutted with the end face of the water outlet of the water outlet. In this way, the fixed seat can be positioned axially (axially of the water outlet) first, and then when the rotating seat located on the outer periphery of the fixed seat is not discharging water, there can be a larger size between the first step surface and the lower end face of the fixed seat to ensure that the ball will not always be in a compressed state. When water is discharging, the nozzle can be driven to perform a short axial movement, but will not separate from the base, so that the whole has a loose and variable structure, which will not be very tight and reduces friction.

[0036] Preferably, it also includes a drain pan 50 and a water inlet pipe 60. The drain pan is used to receive the flushing water flow. The water inlet pipe is used to provide a water source and be fixed on the table (installation surface). The drain pan is sleeved on the outer periphery of the water inlet pipe. A boss 61 is provided on the outer periphery of the water inlet pipe. The drain pan is supported on the boss. The base is provided in the water inlet pipe. The water flow of the water inlet pipe can be connected to the water outlet hole of the base. A spring 62 is provided between the base and the water inlet pipe. The base is also provided with a spring that can be connected to the cup body. The matching pressure plate 70 is located in the drain pan, and the cup body is buckled on the periphery of the nozzle on the pressure plate. At the same time, the pressure plate is a detachable structure and can be easily extracted upward for cleaning. After installation, the drain pan and the water inlet pipe do not move up and down. By pressing the cup body, the base and the nozzle move downward, the water channel is opened, and water flows out from the water outlet through the water outlet hole to clean the cup body. After loosening, the spring can be reset, the water channel is closed, and the water in the water inlet pipe cannot flow to the water outlet and the water outlet hole.

[0037] Furthermore, it also includes a piston rod 80 located below the base, a convex ring 63 is provided in the water inlet pipe, a water outlet 64 is formed in the middle of the convex ring, the spring is located between the convex ring and the base, and is also sleeved on the outer periphery of the piston rod; a water passage 81 that can be connected to the water inlet pipe and the water outlet is provided in the piston rod, and a water inlet hole 82 that can be connected to the water passage is provided on the side wall of the piston rod. The upper end of the piston rod can be fixedly connected to the base, and the lower end of the piston rod is provided with a spring located below the water inlet hole. The sealing gasket 83 can abut against the lower end surface of the convex ring to prevent water from flowing into the water channel and the water outlet. That is, when the pressure plate is not under pressure, the spring acts to keep the sealing gasket in close contact with the lower end surface of the convex ring, achieving a seal so that water from the water inlet pipe cannot flow into the water channel. Only by pressing the pressure plate and compressing the spring can the entire base assembly move downward, separating the sealing gasket from the convex ring, and allowing water in the water inlet pipe to flow into the water channel through the water inlet hole and then be ejected from the water outlet. A sealing ring 90 is provided between the water inlet pipe and the base, and a sealing ring 91 can also be provided between the drain pan and the outer periphery of the water inlet pipe to ensure that water does not flow onto the countertop and that water from the drain pan flows directly into the sink. The lower end of the piston rod is provided with an annular groove 84 located below the water inlet hole, and the sealing gasket is disposed in the annular groove.

[0038] More specifically, the present invention includes the following: 1. The cup washer nozzle has at least one eccentric water outlet (the outlet is not limited to a hole-shaped outlet; it can be round, square, or sheet-shaped, with sheet-shaped being the preferred shape). Alternatively, a water outlet unit coaxially arranged with the outlet can be provided. 2. The nozzle is fixed to a rotating base. When water is discharged, the eccentric water outlet provides rotational power, which, through aerodynamic back-propulsion, drives the nozzle and rotating base. 3. A ball bearing is positioned between the rotating base and the fixed base (or base) to reduce friction on the contact surface during rotation. The fixed base is fixedly connected to the base. 4. The pressure plate and drain pan are detachable. The drain pan is positioned on the periphery of the water inlet pipe and pre-tightened by a sealing ring 91. The pressure plate is positioned on the periphery of the base, allowing for convenient removal for daily cleaning.

[0039] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
