Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a fluid collection power cleaning method for household appliances.

[0002] Brush head. Background Art

[0003] In order to meet the fluid cleaning requirements of the surface to be cleaned, the following three methods are generally used in the prior art to solve this problem:

[0004] The first is to arrange a ventilation duct at the front end of the cleaning component of the power cleaning brush head to collect the fluid on the surface to be cleaned;

[0005] Because the front ventilation duct is longer than the rear ventilation duct and there is no unobstructed rear ventilation duct, the cleaning capacity of the whole machine is greatly consumed; and the existing technology achieves the so-called "ideal" cleaning effect by reducing the cross-section or layout of the front ventilation duct. During the cleaning process, when cleaning a solid-liquid mixed fluid with slightly larger particles or a mixed fluid with fibers (such as cotton wool, hair, etc.), the ventilation duct may be blocked or partially remain or even cannot be collected, forcing users to selectively collect domestic waste, which brings inconvenience to users.

[0006] The second method is to arrange a ventilation duct at the rear end of the cleaning component of the power cleaning brush head to collect the fluid on the surface to be cleaned;

[0007] During the movement of the cleaning components, some liquid waste will remain with the movement of the components or the cleaning action needs to be repeated many times before it can be collected. This is time-consuming and laborious for users to use and does not give a good physical experience.

[0008] The third method is to arrange ventilation ducts at the front and rear ends of the cleaning components of the power cleaning brush head at the same time, but this method is mainly used to clean dry garbage in household life, such as dust and other fine particles or small particles of garbage, and is not suitable for collecting fluid garbage or large particles of garbage; because the ventilation duct layout of this method consumes a lot of the cleaning capacity of the whole machine, the ventilation duct is easy to be blocked when cleaning dirty fluids, and it is not easy to clean. There are residues or large particles that cannot be collected after cleaning, and there are disadvantages such as relatively complex structure and relatively high cost. Summary of the invention

[0009] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a fluid collection power cleaning brush head for household appliances, which can clean various garbage in daily life, especially fluid garbage, clean it without residue, is easy to use and has low energy consumption.

[0010] In order to achieve the above object, the present invention adopts the following technical solution:

[0012] A cleaning component is provided at the front end of the base, the cleaning component is rotatably connected to the base, and a main ventilation duct is provided at the rear side of the cleaning component inside the chamber;

[0013] A scraper and a transparent cover are provided in the chamber, the scraper contacts the cleaning component, and the scraper is connected to the base;

[0014] The transparent cover plate is detachably connected to the scraper plate, and the two together define a semi-enclosed auxiliary ventilation duct, which is connected to the main ventilation duct and the ventilation pipe; an opening is provided on the scraper plate, and the opening is located in the auxiliary ventilation duct.

[0015] Furthermore, an interference E is provided between the scraper and the cleaning component, and 0≤E≤7mm.

[0016] Furthermore, the number n of the openings is in the range of 1≤n≤100.
