[0002] A tea cup cleaning machine is disclosed in Chinese Patent Publication No. CN 115778278 A. The tea cups to be cleaned are inverted and placed on the resting net rack, and the tea cups are sprayed and cleaned by the spray head below the resting net rack. However, if there is residual tea in the mouth of the tea cup to be cleaned, it is very easy to be pressed between the mouth of the tea cup and the upper surface of the resting net rack and difficult to be cleaned and removed by the spray head.

The cleaning arm includes two rotating spray heads, and the rotation of the rotating spray heads relative to the cleaning arm is driven by the water flow flowing into the spray head to drive the impeller inside the spray head. However, different speed adjustments of different spray heads cannot be achieved, and the torque of the impeller depends on the speed of the water flow flowing through the spray head. When the water spraying speed of the spray head needs to be adjusted, the rotation speed will also be inevitably affected. SUMMARY

[0040] The upper surface of the end of the cleaning arm 2 is provided with a water outlet end 23 in communication with the cavity 21;

[0041] The rotary spray head 22 is provided with a hollow shaft 222 in communication with the spray hole 221;

[0042] The hollow shaft 222 is in rotary sealing cooperation with the water outlet end 23 of the cleaning arm 2;

[0043] The cavity 21 is internally provided with a driven magnet 223 coaxially connected with the hollow shaft 222; the lower surface of the end of the cleaning arm 2 is provided with a driving magnet 224; the driving magnet 224 and the driven magnet 223 are coupled by magnetic force.

[0044] The driving magnet 224 and the driven magnet 223 each include at least one neodymium-iron-boron magnetic block; the magnetic block in the driving magnet 224 and the magnetic block in the driven magnet 223 are mutually attracted. Specifically, the driving magnet 224 is an annular magnetic block coated with plastic on the outside; the driven magnet 223 is a plastic structural member provided with an annular magnetic block on the bottom. The driving magnet 224 and the driven magnet 223 are close to each other and are isolated by the inner cavity wall of the end of the cleaning arm 2. The driving magnet 224 is in clearance cooperation with the lower surface of the end of the cleaning arm 2; the distance between the driving magnet 224 and the driven magnet 223 is 3-5 mm.

[0045] The upper surface of the cleaning arm 2 is provided with a plurality of water spray holes.

[0046] The inner cavity wall of the end of the cleaning arm 2 is provided with a support rotating shaft 225 cooperating with the driven magnet 223.

[0047] The lower end surface of the driven magnet 223 is in clearance cooperation with the inner cavity wall of the cleaning arm 2.

[0048] The upper end of the driven magnet 223 is detachably connected with the hollow shaft 222.

[0049] The hollow shaft 222 is coaxially provided with a circumferential limiting shaft 226; the upper end of the driven magnet 223 is provided with a circumferential limiting hole 227 cooperating with the circumferential limiting shaft 226.

[0050] The cleaning arm 2 is equipped with a stepper motor 24 whose output shaft is coaxially connected to the drive magnet 224.

[0051] The outer peripheral wall of the water outlet 23 is provided with an annular flange; the rotating nozzle 22 is provided with an axial limiting fastener 228 that cooperates with the annular flange; the hollow shaft 222 is movably sleeved in the water outlet 23 and is axially limited by the cooperation of the axial limiting fastener 228 and the annular flange.

[0052] When the circular shelf 3 rotates relative to the cleaning arm 2, the scanning range of the rotating nozzle 22 covers the U-shaped limiting frame.

[0053] The rotary drive motor 4 and the stepper motor 24 are connected to the main controller via a drive circuit.

[0054] like Figure 3 As shown, the teacup to be cleaned is placed sideways inside the U-shaped limiting bracket 32, with the rim of the teacup aligned with two rim baffles 321, the sidewall of the teacup against two wall baffles 322, and the bottom of the teacup against two bottom baffles 323. The U-shaped limiting bracket 32 ​​is rotatably connected to the mounting shaft 31 via a sleeve hole on the rim baffle 321. Below the circular shelf 3, there is a ring 34 hinged to the drive arm 324 of each U-shaped limiting bracket 32. The ring 34 has a protrusion 341. The bottom of the circular shelf 3 has limiting baffles 35 on both sides of the protrusion 341, limiting the range of motion of the protrusion 341. The swing amplitude can be controlled by setting the distance between the limiting baffles 35. Since the distance between the rim baffle 321 and the bottom baffle 323 is greater than the height from the bottom to the rim of the teacup to be cleaned, the teacup placed inside has a certain amount of room to move.

[0055] When the rotary drive motor 4 at the bottom of the water supply tank 11 drives the central shaft 33 to rotate the circular shelf 3 relative to the cleaning arm 2, the water sprayed from the cleaning arm 2 can clean the teacup. The impact force of the sprayed water can cause the U-shaped limiting frame 32 to swing at a certain angle around the mounting shaft 31. During the swinging process, any part of the teacup is in active contact with the U-shaped limiting frame 32, and is not in a static state. During the process of spraying and cleaning the teacup from the bottom up, it can avoid the formation of a stable sanitary dead corner between the mouth of the teacup and the cup holder, which would make it difficult to remove residual tea leaves by spraying and cleaning.

[0056] The cleaning arm 2 is connected to the water pipe 12 to input water with pressure, and the water is guided into the hollow shaft 222 through the water outlet end 23, and sprayed out of the spray holes 221 of the rotating spray head 22 to clean the cup, and part of the water flow is directly sprayed out of the water spray holes on the cleaning arm 2; since the hollow shaft 222 is in rotational sealing communication with the water outlet end 23 of the cleaning arm 2, and the driving magnet 224 is coupled with the driven magnet 223 through magnetic force. The driving magnet 224 is driven by the stepping motor 24 to drive the driven magnet 223 to rotate, and since the circumferential limiting shaft 226 is coaxially arranged in the hollow shaft 222, and the circumferential limiting hole 227 is arranged at the upper end of the driven magnet 223 and cooperates with the circumferential limiting shaft 226. In this embodiment, the cross sections of the circumferential limiting shaft 226 and the circumferential limiting hole 227 are regular hexagons, and the circumferential limiting shaft 226 is fixed by the star-shaped ribs arranged radially along the inner wall of the hollow shaft 222. Therefore, the driven magnet 223 drives the rotating spray head 22 to rotate and spray. Two rotating spray heads 22 can be independently adjusted at different speeds, since the rotating spray head 22 is connected to the water outlet end 23 through the axial limiting buckle, and the circumferential limiting shaft 226 is circumferentially limited by the circumferential limiting hole 227. Therefore, the structure of the cleaning arm 2 of this embodiment also facilitates the disassembly and cleaning of the rotating spray head 22.

[0057] Since the scanning range of the rotating surface of the rotating spray head 22 is located directly below the cup to be cleaned, the water column of the rotating spray head 22 can be focused on the cup to rotate and scan for batch cleaning.
