Description

Technical Field

[0001] This invention relates to the field of multifunctional tea bar machine technology, specifically a teacup cleaning device. Background Technology

[0002] Chinese Patent Publication No. CN 115778278 A discloses a teacup washing machine. The teacup to be washed is placed upside down on a mesh rack, and a spray nozzle below the rack sprays water onto the cup. However, because the rim of the teacup remains in contact with the upper surface of the mesh rack, any residual tea leaves at the rim are easily trapped between the rim and the rack, making them difficult to remove with the spray nozzle. Even residual tea leaves inside the cup may slip into this area during washing, making them difficult to remove. The washing arm includes two rotating nozzles, whose rotation relative to the arm is driven by the water flow into the nozzles, which in turn drives an internal impeller. However, this design cannot adjust the speed of different nozzles, and the impeller's torque depends on the speed of the water flow. Therefore, when adjusting the spray speed, the impeller's rotation speed is inevitably affected. Summary of the Invention

[0038] The ring 34 is provided with a protrusion 341; the bottom of the circular shelf 3 is provided with a limiting stop bar 35 on both sides of the protrusion 341 to limit the range of motion of the protrusion 341. Preferably, the limiting swing angle is 35°.

[0039] The circular shelf 3 has a fence 36 on its outer edge. The circular shelf 3 is welded together from multiple radial and circumferential grid strips.

[0048] The driving magnet 224 and the driven magnet 223 each include at least one neodymium iron boron magnet. The magnets in the driving magnet 224 and the driven magnet 223 attract each other. Specifically, the driving magnet 224 is an annular magnet covered with plastic; the driven magnet 223 is a plastic structure with an annular magnet at its bottom. The driving magnet 224 and the driven magnet 223 are close to each other and separated by the inner wall of the end of the cleaning arm 2. The driving magnet 224 is clearance-fitted 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.

[0049] The upper surface of the cleaning arm 2 is provided with several water spray holes.

[0050] The inner wall of the end of the cleaning arm 2 is provided with a support shaft 225 that cooperates with the driven magnet 223.

[0051] The lower end face of the driven magnet 223 is fitted with the inner wall of the cleaning arm 2 with a clearance.

[0052] The upper end of the driven magnet 223 is detachably connected to the hollow shaft 222.

[0053] The hollow shaft 222 is coaxially provided with a circumferential limiting shaft 226; the driven magnet 223 is provided with a circumferential limiting hole 227 at its upper end that cooperates with the circumferential limiting shaft 226.

[0054] The cleaning arm 2 is equipped with a stepper motor 24 whose output shaft is coaxially connected to the drive magnet 224.

[0055] 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.

[0056] 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.

[0057] The stepper motor 24, the rotary drive motor 43, and the lifting drive motor 44 are connected to the main controller via a drive circuit.

[0058] like Figure 3As 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.

[0059] When the lifting and rotating drive mechanism 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.

[0060] The cleaning arm 2 is supplied with water at a certain pressure through the water supply pipe 12. The water is introduced into the hollow shaft 222 through the water outlet 23 and sprayed out of the spray hole 221 of the rotating nozzle 22 to clean the cup. Some water is sprayed directly out through the spray hole on the cleaning arm 2. The hollow shaft 222 and the water outlet 23 of the cleaning arm 2 are rotatably sealed and connected. The driving magnet 224 and the driven magnet 223 are magnetically coupled. The stepper motor 24 drives the driving magnet 224 to drive the driven magnet 223 to rotate. 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 that cooperates with the circumferential limiting shaft 226. In this embodiment, the cross-section of the circumferential limiting shaft 226 and the circumferential limiting hole 227 are both regular hexagonal. The circumferential limiting shaft 226 is fixed by a star-shaped rib arranged radially along the inner circumferential wall of the hollow shaft 222. Thus, the driven magnet 223 drives the rotating nozzle 22 to rotate and spray. The two rotating nozzles 22 can be independently adjusted at different speeds. Since the rotating nozzle 22 is axially limited and fastened to the water outlet 23, and the circumferential limiting shaft 226 is sleeved with the circumferential limiting hole 227 for circumferential limiting, the cleaning arm 2 structure of this embodiment also facilitates the disassembly and cleaning of the rotating nozzle 22.

[0061] Since the scanning range of the rotating surface of the rotating nozzle 22 is located directly below the teacup to be cleaned, the rotating drive motor 43 drives the circular shelf 3 to rotate, enabling the water jet of the rotating nozzle 22 to clean multiple teacups in batches. The lifting drive motor 44 drives the circular shelf 3 to lift, making the distance between the circular shelf 3 and the rotating nozzle 22 variable. This changes the impact force of the sprayed water on the teacup to be cleaned, making the rotation range of the U-shaped limiting frame 32 variable, ultimately allowing the teacup to be cleaned more thoroughly in different postures.
