[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0030] Referring to the drawings of the specification, a self-rotating cup washing device comprises a base 10 having a water outlet 11, and also comprises a nozzle 20. The nozzle is provided with at least one eccentric water outlet 21, wherein the eccentricity here is relative to the axis C. Of course, it can also have a jet port 22 coaxial with the rotation axis of the nozzle. The water flow of the water outlet can be ejected through the water outlet to clean the cup body; the nozzle can be located at the periphery of the water outlet. In one embodiment, the nozzle is buckled at the periphery of the water outlet. The water flow ejected from the water outlet through the water outlet can drive the nozzle to rotate relative to the base. When the water flow of the water outlet hits the inner peripheral wall of the nozzle, water is discharged through the water outlet eccentrically arranged with the water outlet. In this way, the nozzle can be driven to rotate relative to the base, and the eccentric water outlet can form a circumferential water flow to clean the inner peripheral wall of the body, and can form a full coverage tilt. It is only necessary to buckle the body at the periphery of the nozzle. The cleaning action is simple, single, and irresponsible. At the same time, through the impact force of water, no other external energy, such as electric energy, is required.

[0031] Preferably, the nozzle sleeve is arranged 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] Further, the nozzle includes a semi-spherical part, which means that the water inlet and outlet of the water outlet are both on the inner and outer surfaces of the semi-spherical part, and both the inner and outer surfaces are spherical. The water outlet is arranged on the semi-spherical part, and the water outlet can be arranged in a staggered manner with the water outlet hole. The shape of the water outlet can be a combination of one or more of a circle, a square, and a strip, preferably a strip shape, which can discharge water from the blade and better clean the inner wall of the cup body. Referring to the attached drawings of the specification, when the water outlet is in a strip shape, its mouth can exceed the center point of the semi-spherical part, that is to say: the axis C of the semi-spherical part, the semi-spherical part 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, the position of the axis C being 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. In 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 with the base, and the nozzle can be screwed with 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 abut and cooperate with the end surface of the water outlet of the water outlet. In this way, the fixed seat can be axially positioned (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 surface 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-stroke axial movement, but it will not separate from the base, so that the whole has a loose and variable structure, which will not be very tight and also 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, the outer periphery of the water inlet pipe is provided with a boss 61, 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 with the water outlet hole of the base, a spring 62 is provided between the base and the water inlet pipe, and the outer periphery of the base is also provided with a spring that can be connected with the cup body The matching pressure plate 70 is located in the drain pan, and the cup body is buckled on the outer periphery of the nozzle on the pressure plate. At the same time, the pressure plate is a detachable structure, which can be easily extracted upwards for cleaning. After installation, the drain pan and the water inlet pipe are prevented from moving up and down. By pressing the cup body, the base and the nozzle are moved downward, the water path is opened, and water flows out from the water outlet through the water outlet hole to clean the cup body. After releasing, the spring can be reset, the water path 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, 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 The sealing gasket 83 can be abutted with the lower end face of the convex ring to prevent the water flow of the water inlet pipe from flowing into the water channel and the water outlet hole. That is to say, when the pressure plate is not under force, under the action of the spring, the sealing gasket keeps in close contact with the lower end face of the convex ring to achieve sealing, and the water flow of the water inlet pipe cannot flow into the water channel. Only by pressing the pressure plate and compressing the spring, the overall assembly of the base moves downward, the sealing gasket is separated from the convex ring, and the water flow in the water inlet pipe flows into the water channel through the water inlet hole and then sprays out from the water outlet. A sealing ring 90 is arranged between the water inlet pipe and the base, and a sealing ring 91 can also be arranged between the drain pan and the outer periphery of the water inlet pipe, so as to ensure that the water flow will not flow to the table, and the water flow of 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 arranged in the annular groove.

[0038] More specifically, the present invention is as follows: 1. There is at least one eccentric water outlet on the nozzle of the cup washer (the water outlet is not limited to the shape of a water outlet hole, a round hole, a square hole, a sheet hole, etc., among which the sheet water is the best shape), and of course there can also be a water outlet unit coaxially arranged with the water outlet; 2. The nozzle is fixed on the rotating seat, and when water is discharged, the eccentric water outlet provides rotational power, and the power is provided by the reverse thrust of the aerodynamic force to rotate the nozzle and the rotating seat; 3. A ball is placed between the rotating seat and the fixed seat (or base) to reduce the friction of the contact surface during rotation, wherein the fixed seat is fixedly connected to the base; 4. The pressure plate and the drain plate are detachable structures, the drain plate is placed on the outer periphery of the water inlet pipe, and is pre-tightened by the sealing ring 91; the pressure plate is placed on the outer periphery of the base. Under normal circumstances, it can be conveniently taken out for cleaning.
