Description

A portable vacuum cleaner and its operation method

technical field

The invention relates to the field of household or vehicle cleaning tools, in particular to a portable vacuum cleaner and an operating method thereof.

Background technique

Different from large vacuum cleaners, portable vacuum cleaners are smaller and easier to carry. The principle is that the fan impeller is driven by the motor at high speed, so that a high pressure difference is formed between the inside and the outside of the vacuum cleaner, so that the dust, debris and other dirt from the outside enter the inside of the vacuum cleaner with the air, and pass through the filter. , to collect dust, debris, etc. in the dust tube, so as to achieve the purpose of cleaning the environment.

The dust collection bin of this type of vacuum cleaner has a limited volume, and the dust collection bin will be full after the vacuum cleaner works for a period of time. It is a detachable connection, so when dumping dust, it is necessary to disassemble the dust collection box from the main body, and sometimes it is necessary to take out the HEPA filter and components from the dust collection box before the dust can be dumped. This process is time-consuming and laborious. It is very cumbersome, affects the working efficiency of the vacuum cleaner, and causes a bad user experience to the user.

In order to solve this problem, CN101119675A discloses a vacuum cleaner with cyclone separation dust cup and dust cup door. The dust cup 116 can be dumped out by opening the dust cup door without removing the dust cup 116 from the housing. . However, the problem with this technical solution is that the structure design of the dust cup and the vacuum cleaner is relatively complicated, and the airflow has a 180-degree back bend during the flow process, which greatly increases the airflow resistance, which will affect the cleaning efficiency of the vacuum cleaner, and the overall appearance of the vacuum cleaner is bloated. .

CN209091167U discloses a portable hand-held high-speed vacuum cleaner. The front end of the dust bucket is hinged with the bottom side of the front end of the main body through a shaft. When the push rod is pushed, the dust bucket can be rotated out of the main body as a whole, and the dust can be poured out, which is very efficient. However, the problem with this vacuum cleaner is that there are two 90° bends on the streamline of the air flow from the suction port to the filter element, and the flow resistance is relatively large, which greatly reduces the cleaning efficiency of the vacuum cleaner, and the structure design of the vacuum chamber is complicated.
