A handheld vacuum cleaner

Abstract

The invention discloses a hand-held vacuum cleaner, which relates to the technical field of vacuum cleaners, and comprises a dust collection mechanism. A holding mechanism is provided on the side, and an extension mechanism is connected to one side of the dust suction mechanism, and a suction head is connected to one side of the extension mechanism. The present invention can effectively avoid its interference with the normal installation of other parts of the casing assembly by setting the dust suction mechanism and the extension mechanism, and does not need to increase the overall size of the casing assembly, so that the appearance of the dust cup assembly is small and beautiful, and it can be used for suction The dust can be further filtered, and the dust can be further filtered, and the polarization of the extension tube can be reduced through the cooperation of the sound-absorbing shell and the sound-absorbing groove while absorbing most of the noise generated by the air circulation, while extending the air inlet path and reducing the air flow rate, thereby significantly reducing The overall environmental noise during vacuuming significantly improves the comfort of use.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a hand-held vacuum cleaner. Background technique [0002] In order to keep the floor clean, vacuum cleaners are often used in modern life to absorb the dust from the ground. In furniture life, due to the high dust holding capacity of carpets, manual cleaning is very inconvenient. Using vacuum cleaners can absorb dust well. Carpet vacuum cleaners are usually Spray or pour such as water or a suitable cleaning liquid on the carpet or other surface to be cleaned, and then use a suction nozzle to remove the poured liquid and the dust contained in the liquid. [0003] The Chinese Invention Patent Publication No. CN108567374A discloses a vacuum cleaner and a hand-held vacuum cleaner, which belong to the technical field of dust collection devices and are designed to solve the problems of existing vacuum cleaners such as high noise and poor heat dissipation of battery packs. The ...

AI Technical Summary

Problems solved by technology

[0004] However, this handheld vacuum cleaner solution has certain disadvantages. 1. The position of the airflow generating device will interfere with the normal installation of other parts of the casing assembly, which leads to an increase in the overall size of the cup casing, making the overall size of the dust cup assembly larger and more beautiful. 2. The noise of the airflow generating device is relatively large during operation, which will bring noise impact to the user's environment during use; 3. The motor of the dust collection device will generate a large amount of heat when it is working, which will affect the internal heat dissipation and lead to the life of electronic components. reduce
