The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-3 The image shows an embodiment provided by this utility model.

[0029] This utility model provides a coffee maker's portafilter cleaner, comprising: a motor 10 and a waterproof housing 20. The waterproof housing 20 is fitted over the motor 10, providing waterproof protection for the entire motor 10. Specifically, the upper end of the waterproof housing 20 is coaxially provided with a clearance hole 21, a waterproof groove 22, a sealing ring 23, and a sealing gasket 24. The clearance hole 21 allows the output shaft 11 of the motor 10 to extend from inside the waterproof housing 20. A portafilter brush can be connected to the output shaft 11 of the motor 10, which drives the portafilter brush to rotate and clean the portafilter. The waterproof groove 22 is arranged around the clearance hole 21, the sealing ring 23 is disposed inside the waterproof groove 22, and the sealing gasket 24 is disposed at the upper end of the waterproof groove 22, used to confine the sealing ring 23 within the waterproof groove 22. The output shaft 11 of the motor 10 extends from the clearance hole 21. The sealing ring 23 and the sealing gasket 24 are respectively movably fitted onto the output shaft 11 of the motor 10. The sealing ring 23 can be made of silicone or rubber and has a certain elasticity, so that it can be tightly connected to the output shaft 11 of the motor 10. The waterproof groove 22 is filled with sealing grease (not shown in the figure). The sealing grease is filled between the sealing ring 23 and the sealing gasket 24. The sealing grease can not only play a waterproof role, but also lubricate the sealing ring 23 and the output shaft 11 of the motor 10, reduce the rotational friction between the sealing ring 23 and the output shaft 11 of the motor 10, and enable the output shaft 11 of the motor 10 to rotate normally and smoothly. After adopting the coffee machine's powder bowl cleaner, the entire motor 10 is waterproofed by the waterproof shell 20 fitted over the motor 10. Then, the sealing ring 23 and sealing gasket 24 fitted on the output shaft 11 of the motor 10 are used to seal the gap between the output shaft 11 of the motor 10 and the clearance hole 21, which can prevent liquid from flowing into the motor 10 along the output shaft 11 of the motor 10 and ensure the normal operation of the motor 10.

[0030] Specifically, internal threaded posts 221 are provided on both sides of the waterproof groove 22. The internal threaded posts 221 are threadedly connected to fixing screws 222. The bottom of the screw head of the fixing screw 222 abuts against the top of the sealing gasket 24, thereby pressing the sealing gasket 24 onto the upper end of the waterproof groove 22, thus limiting the sealing ring 23.

[0031] Specifically, the upper end of the waterproof housing 20 is provided with a connection hole 25, and the upper end of the motor 10 is provided with a corresponding threaded hole 12. The connection hole 25 and the threaded hole 12 are connected by a screw 13, thereby connecting and fixing the motor 10 and the waterproof housing 20.

[0032] Furthermore, a buffer spring 14 is provided on the outer sleeve of the screw 13. The lower end of the buffer spring 14 abuts against the top wall of the waterproof shell 20, and the upper end of the buffer spring 14 abuts against the bottom of the screw head of the screw 13, so that the motor 10 can move up and down relative to the waterproof shell 20. Since the powder bowl cleaner needs to be placed upside down on the powder bowl brush when in use, the downward pressure of the powder bowl will exert downward pressure on the output shaft 11 of the motor 10. The buffer spring 14 can provide a certain buffering effect on this downward pressure, which can reduce the damage to the output shaft 11 of the motor 10 and extend the service life of the motor 10.

[0033] Furthermore, a limiting sleeve 15 is sleeved between the screw 13 and the buffer spring 14. The length of the limiting sleeve 15 is less than the length of the buffer spring 14 and the screw 13. The limiting sleeve 15 is used to limit the degree of deformation of the buffer spring 14.

[0034] Furthermore, a waterproof ring 26 is provided around the outer perimeter of the buffer spring 14. The lower end of the waterproof ring 26 is connected to the waterproof shell 20, and the upper end of the waterproof ring 26 is connected to a waterproof cap 27. The waterproof cap 27 is made of silicone. The waterproof cap 27 can prevent liquid from entering the interior of the waterproof shell 20 through the connection hole 25 along the screw 13, and can also prevent liquid from getting on the buffer spring 14 and the screw 13.

[0035] Specifically, a mounting cover 28 is provided at the lower end of the waterproof housing 20. The mounting cover 28 is detachably connected to the waterproof housing 20, which facilitates the installation of the motor 10 into the waterproof housing 20.

[0036] Specifically, a mounting base 29 is provided on the outer wall of the waterproof shell 20. The interior of the mounting base 29 is connected to the interior of the waterproof shell 20. Internal functional components such as power supply and control module can be installed inside the mounting base 29. The mounting base 29 can also be used to install and fix the waterproof shell 20 to other supports so that users can better use the bowl cleaner.

[0037] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
