[0002] An appliance used in the market to clean single-sided open cups such as teacups, water cups, teapots, kettles, milk tea cups, etc. is called a teacup cleaning machine. Traditional teacup cleaning machines can only perform water spraying or water bath soaking, and cannot effectively clean the tea residues at the bottom of the cup, resulting in a general cleaning effect. With the development of technology, in recent years, there has emerged a cleaning machine that can better clean cups after placing the teacup upside down. For example, the Chinese invention patent application: Application No. 202211462345.X discloses a teacup cleaning machine that sprays water from a nozzle below to clean the teacup, achieving a better cleaning effect. However, the disadvantage is that the nozzle part of this cleaning machine has a complex structure and needs to rely on the power output of a rotary drive motor to rotate. Installing the motor not only occupies the installation space of other parts of the cleaning machine but also consumes electricity. If the nozzle structure can be optimized so that it can rotate by utilizing the water kinetic energy during water spraying, it will surely better meet the usage requirements of the cleaning machine.

[0021] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected to" 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] As Figures 1 - 3 shown, a rotary cup flushing nozzle can be used for single-opening cups such as teacups, water cups, teapots, kettles, milk tea cups, soybean milk cups, fruit cups, etc. It includes a mounting shaft 1 and a rotary nozzle 2. The rotary nozzle 2 is rotatably connected above the mounting shaft 1, and the mounting shaft 1 and the rotary nozzle 2 are coaxially arranged. A water channel 11 is provided inside the mounting shaft 1, and a water spraying chamber 21 is provided inside the rotary nozzle 2. The water channel 11 communicates with the water spraying chamber 21. Water can be driven by a water pump to enter the water channel 11 from below and then be transported to the water spraying chamber 21. A rebound surface 22 is provided at the rear side of the water spraying chamber 21, and a water spraying groove 23 is provided on the outer side of the rotary nozzle 2. The front side of the water spraying chamber 21 communicates with the water spraying groove 23, and a turning groove 24 is provided at the end of the water spraying groove 23. The water entering the water spraying chamber 21 will impact the rebound surface 22, and the rebound surface 22 guides the water into the water spraying groove 23. The water impacts the inner wall of the turning groove 24 under the guiding action of the water spraying groove 23. Since the corner of the turning groove 24 is not parallel to the water spraying groove 23, the inner wall of the turning groove 24 will cause the rotary nozzle 2 to rotate when it is stressed.

[0025] Specifically, the turning groove 24 turns in a clockwise direction or a counterclockwise direction. Different turning directions will change the rotation direction of the nozzle. In Figure 2 the turning groove 24 turns in a counterclockwise direction. When working, the inner wall of the turning groove 24 is stressed to make the rotary nozzle 2 rotate clockwise, and vice versa.

[0026] As Figure 4 shown, the outer shape of the turning groove 24 is an arc groove or an inclined groove, the water spraying groove is a straight groove, the center line A of the turning groove 23 and the center line B of the water spraying groove 22 form an inclination angle C, and the rebound surface 22 is an arc surface or an inclined surface. Various matching methods enable the water impact to make the nozzle rotate.

[0027] As Figure 4 and 5 shown, the main body of the rotary nozzle 2 is a cylinder 2a, the upper part of the cylinder 2a is connected to a mushroom-shaped sheet part 2b, the side of the cylinder 2a and the sheet part 2b is a convex part 2c, the upper openings of the water spraying grooves 23 and the turning grooves 24 are located in the sheet part 2b, so that part of the water can be sprayed out from the upper openings to clean the upper cups, and the end opening of the turning groove 24 is located in the convex part 2c. This unique structural design of the rotary nozzle 2 makes it easier to rotate.

[0028] Specifically, a convex step 12 is provided at the upper end of the mounting shaft 1. The convex step 12 is installed inside the rotary nozzle 2 and is located in the water spraying chamber 21. The outer diameter of the convex step 21 is larger than the outer diameter of the main body 13 of the mounting shaft. A bearing 3 is sleeved on the outer peripheral side of the main body 13 of the mounting shaft. The bearing 3 is installed in the bearing mounting cavity 25 of the rotary nozzle 2. The bearing mounting cavity 25 is located below the water spraying chamber 21. The bearing 3 can make the rotary nozzle 2 rotate more easily.

[0029] As Figure 5 shown, a snap ring groove 26 is provided at the lower part of the rotary nozzle 2. The inner side of the snap ring groove 26 communicates with the bearing mounting cavity 25. A limit snap ring 4 is installed in the snap ring groove 26. The limiting edge of the limit snap ring 26 extends into the snap ring groove 26 to hold the bearing 3, which can prevent the rotary nozzle 2 from separating from the mounting shaft 1.

[0030] Working principle: As Figure 7 shown, a water pump or other power device is used to drive water to enter the water channel 11 from below. After the water is delivered to the water spraying chamber 21, part of the water is sprayed out from the upper opening of the water spraying groove 23, and part of the water will hit the rebounding surface 22. The rebounding surface 22 laterally guides the water into the water spraying groove 23. The water impacts the inner wall of the turning groove 24 under the guiding action of the water spraying groove 23, and the rotary nozzle rotates by itself without relying on the drive of a motor. The structural design is ingenious.

[0031] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
