Background technique

In daily life and work, it is easy for some small stains to stick to the clothes when eating, playing, etc. If the whole piece is removed, since more than 90% of the clothing is clean, the whole cleaning will waste water. On the other hand, some clothing is only suitable for dry cleaning, and some clothing materials are not suitable for frequent cleaning. And if the stains on the clothes are not removed immediately, it will often greatly increase the difficulty of local stain removal.

detailed description

In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings 1-3. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Since the eccentric block 530 is eccentrically arranged relative to the center of the rotating wheel 500, the eccentric block 530 will generate an inertial force along the stretching direction of the spring 400 during the rotation process, and the inertial force can drive the second housing 200 to reciprocate up and down along the stretching direction of the spring 400, The second housing 200 compresses the spring 400 back and forth, and then drives the beating head 300 connected to the spring 400 to continuously expand and contract for beating. Specifically, during the downward movement of the eccentric mass 530 along the direction shown by A in FIG. 1 , a downward inertial force is generated. The second housing 200 compresses the spring downwards, so that the beating head 300 connected to the spring 400 moves out of the first housing 100 while the spring 400 stores energy. On the contrary, during the upward movement of the eccentric weight 530 along the direction B in FIG. 1 , an upward inertial force is generated.
