Ash-scraping structure

Abstract

The invention discloses an ash-scraping structure. The ash-scraping structure comprises a dust collecting tube, an ash-scraping tube, and an air draft tube; the internal of the dust collecting tube ishollow, and end parts of the dust collecting tube are opened so as to form an air inlet port and a fitting port at two ends; the internal of the ash-scraping tube is hollow, and one end thereof is internally connected with the fitting port of the dust collecting tube; the internal of the air draft tube is hollow, and the air draft tube is separately butted joint with the fitting port of the dustcollecting tube; when the air draft tube is butted joint with the fitting port of the dust collecting tube, the ash-scraping tube is coaxially embedded into the air draft tube, and an ash-scraping ring is fixedly connected to a place, connected with the dust collecting tube, on the ash-scraping tube. Through the ash-scraping structure arranged on a filter screen, the dirt accumulated on the filterscreen can be scraped and cleaned without dismounting a dust-air separating structure, the ash-scraping is simple and easy to operate, and an operator and an operation space cannot be polluted, the cleanliness of a dust collector and the clean class in the cleaning process are enhanced, and the ash-scraping structure has extensive market application prospect.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a dust scraping structure. Background technique [0002] Existing vacuum cleaners generally adopt a cyclone separation structure for dust and gas separation. This dust and gas separation structure is very easy to accumulate and entangle a large amount of dust, cotton wool and other dirt on its filter screen during the working process. When it is necessary to clean up these accumulated dirt , the dust cup, filter and other components need to be disassembled. The disassembly is cumbersome and the assembly is error-prone. Frequent disassembly and assembly can easily lead to loosening of the various components, which reduces the service life of the vacuum cleaner and the dust removal effect. In addition, during disassembly During the installation process, the operator's hands are easily polluted by a large amount of dirt, and the operation space is also easily caused by secondary pollu...
