Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings, and the aforementioned and other objects, features, aspects and advantages of the present invention will become more apparent, so that those skilled in the art can implement them with reference to the description. In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like parts. In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are based on the orientation or positional relationship shown in the drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. These relative terms are for convenience of description and are generally not ...

Abstract

The present invention provides a cleaning device which comprises a main body part on which a filter for filtering dust air is mounted, and an air inlet pipeline through which the dust air is introduced into the filter; the device also comprises a dust cup which moves close to the air inlet pipeline; and an ejection device, wherein one end of the ejection device is installed on the main body part, the other end of the ejection device abuts against the dust cup, an ash scraping part is installed on the ejection device, and the an ash scraping part abuts against or abuts against the filter; when the ejection device moves, the abutting dust cup is pushed to move, and meanwhile the dust scraping part scrapes the filter. The automatic ash scraping can be achieved while the ejection dust cup moves; in the ejection process of the dust cup, the dust cup is tightly attached to the air inlet pipeline, and an overlapping part exists between the dust cup and the air inlet pipeline, so that dust in a first-stage dust area is reduced or prevented from entering the air inlet pipeline, and dust raising is reduced or avoided; in the ejection process of the dust cup and after ejection, the first-stage dust area between an outer barrel and an inner barrel is always sealed, dust raising is effectively prevented, and the influence on user experience and the dust collection effect is reduced or avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of cleaning devices, in particular to a cleaning device. 【Background technique】 [0002] A vacuum cleaner is a commonly used cleaning device that can generate very strong suction to suck dust or foreign matter accumulated on floors, carpets, walls, or other surfaces into its garbage collection device. [0003] Conventional vacuum cleaners use motors to generate air negative pressure in a sealed housing, and under the action of pressure difference, dust-containing air is sucked in. In common hand-held vacuum cleaners, dust scraping parts are often set up to scrape dust from other parts, and ash collection tubes or dust cups are used to hold dust. , the structure and operation are complicated, and it is extremely easy to cause dust to fly when the dust cup is opened and the dust is scraped. [0004] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. 【Content of ...
