Problems solved by technology

This kind of vacuum cleaner can accommodate more than two motors, and each motor has a corresponding air inlet. According to the cleaning area and other factors, you can choose to turn on only one motor or turn on multiple motors at the same time for cleaning operations. When only one motor is used, The air duct of the vacuum cleaner needs to be converted, and the unopened motor air inlet should be closed, otherwise the internal or external airflow of the vacuum cleaner may enter the air inlet of the running motor through the unclosed motor air inlet, which will cause the airflow inside the vacuum cleaner to be disordered, causing Reduced suction power of the vacuum cleaner affects the cleaning ability of the vacuum cleaner

Embodiment approach

[0035] like Figure 8 and 9 Shown is the fourth embodiment of the present invention. In this embodiment, the control valve is a tumble valve 40 , and the tumble valve is located between the first air inlet 173 and the second air inlet 168 . The flip valve 40 has a cover plate 403 capable of covering the second air inlet. The flip valve 40 also has an end portion 404, which is connected to the cover plate 403. The end portion 404 is provided with a rotating shaft 401. The rotating shaft 401 cooperates with the shaft hole in the motor cavity 165, so that the cover plate 403 can rotate around the rotating shaft. The limit block 402 is also provided on the edge of the junction between the end 404 and the cover plate 403, and the limit block 402 protrudes from the upper part of the end. When the cover plate 403 turns to a certain angle, the limit block 402 and the stopper located in the motor cavity block 55, the stopper 55 prevents the cover plate 403 from continuing to rotate, ...

Abstract

The invention discloses a vacuum cleaner, which includes a motor providing suction, the motor has a first air inlet, the motor is placed in a motor chamber, and a second air inlet is provided on the motor chamber, the first air inlet and the second A control valve is provided between the air inlets. After the motor is started, the control valve automatically opens the second air inlet. An elastic member is provided between the first air inlet and the second air inlet. After the motor is turned off, the elastic member A restoring force is provided to the control valve so that the control valve automatically closes the second air inlet. The technical solution of the present invention relies on the motor’s open state to automatically realize the mutual conversion of the air ducts, without manual adjustment or an additional action adjustment mechanism. At the same time, the parts are small in size, light in weight, and easy to install, which belongs to the smooth process in the whole machine assembly process Bit operation, and the three positions are common, no wrong installation.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a vacuum cleaner with multiple motors. Background technique [0002] Vacuum cleaners suitable for industrial use generally need to provide greater suction than ordinary vacuum cleaners to clean large areas faster and better, thus resulting in vacuum cleaners equipped with multiple motors. This kind of vacuum cleaner can accommodate more than two motors, and each motor has a corresponding air inlet. According to the cleaning area and other factors, you can choose to turn on only one motor or turn on multiple motors at the same time for cleaning operations. When only one motor is used, The air duct of the vacuum cleaner needs to be converted, and the unopened motor air inlet should be closed, otherwise the internal or external airflow of the vacuum cleaner may enter the air inlet of the running motor through the unclosed motor air inlet, which will cause the airflow inside the vacuum cleaner to ...
