Three-mode optimal dust collector filter bag

Abstract

The invention discloses a three-mode optimal dust collector filter bag which comprises a dust filter bag body. The dust filter bag body is connected with a bracket arranged on an air inlet of a dust collector and is divided into a first dust filter bag and a second dust filter bag by cutting lines, a turning plate and a sensor switch are arranged at joints of the bracket and the first dust filterbag and / or joints of the bracket and the second dust filter bag, and a rotary shaft which is connected with the first dust filter bag or the second dust filter bag is arranged on the turning plate; the first dust filter bag is filled with filter substances in an absorption manner at first when the dust collector works, signals can be transmitted to a stepper motor when the fact that the first dustfilter bag is full is sensed by the sensor switch, and the rotary shaft can be driven by the stepper motor, so that the turning plate can be turned over towards the first dust filter bag, the filtersubstances can be blocked from being fed into the first dust filter bag, and the second dust filter bag can continue to be filled with the filter substances. The three-mode optimal dust collector filter bag has the advantages that the three-mode optimal dust collector filter bag is simple in structure, the suction balance of the dust collector can be guaranteed, suction spaces between the three-mode optimal dust collector filter bag and the motor can be guaranteed, suction effects of the three-mode optimal dust collector filter bag can be strengthened, and filter effects can be enhanced to thegreatest extent.

Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a three-mode optimized filter bag for vacuum cleaners. Background technique [0002] The working principle of the vacuum cleaner is that the motor of the vacuum cleaner rotates at a high speed, and the air is sucked in from the suction port to make the dust box generate a certain vacuum. In the dust filter bag, the filtered air enters the motor through a layer of filter, and the air entering the motor flows out through the motor and is discharged from the air outlet. [0003] The so-called filter bag refers to a bag-shaped filter device, which usually has an air inlet, and the airflow mixed with dust enters from the air inlet, and the airflow flows out of the filter bag from around the filter bag, while the dust is left in the filter bag middle. In the prior art, filter bags are made of various materials according to different filtering requirements, such as filter paper or filte...

Problems solved by technology

However, for smaller vacuum cleaners, the volume of the vacuum cleaner collection bucket is small, and only smaller filter bags can be used, especially for short and long filter bags, which are easy to clog when filtering larger particles of dust and debris around the mouthpiece

[0004] The filter bag of the vacuum cleaner is mainly used to collect and filter the dust inhaled by the vacuum cleaner. The fine dust will stay on the surface of the filter bag material. As the amount of retained dust increases, the wind resistance of the filter bag material also rises. After reaching a certain level, the filter bag will be It can't be used anymore. At present, the filter bag has the following defects: 1. When the garbage accumulates in the dust filter bag to a certain extent, its exhaust effect will be greatly reduced, because it is partially blocked, the suction will be greatly reduced, and the dust removal The effect is severely reduced; 2. The current dust filter bag is directly connected to the motor. When the motor is running, the dust filter bag will be adsorbed on the motor, which will affect the suction effect; It is designed according to the chamber of the vacuum cleaner. In order to prevent the filter bag from being damaged or exploded during use, the size of the filter bag is just attached to the wall of the chamber, and the wall of the chamber is used to support the filter bag to prevent the suction from being too large during use. Damaged or burst filter bag

[0006] In the above invention, the dust filter bag has a complex structure and can only be used in specific vacuum cleaners
