Dust collecting device

Abstract

The invention discloses a dust collecting device. The dust collecting device comprises a rear end part, wherein the right side of the rear end part is movably provided with a front end part; a dust-absorbing narrow hole is formed in the right side of the front end part; the right end of the rear end part is in threaded connection with a dust collecting bag; a cavity is arranged inside the rear endpart; the right side of the cavity is fixedly provided with a fan; the surface of the fan is fixedly connected with soundproof sponge; and the left side of the fan is fixedly connected with an air compression hopper. The dust collecting device can effectively reduce noises in use, avoids affecting life and work of people around; and a dust sucking hole is relatively small in design at the same time, a sanitary dead angle can also be cleaned, so that bacteria and worms can be avoided; in a using process, the dust collecting device can be dismounted for cleaning the inner part, so that the dustsucking effect is guaranteed; and finally, secondary filtration and sterilization disinfection further can be performed, so that discharged air can be purified.

Description

technical field [0001] The invention relates to the technical field of dust collection equipment, in particular to a dust collection device. Background technique [0002] In the field of laboratory electrical appliances, vacuum cleaners, as an important part, have the functions of absorbing dust and cleaning utensils. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, and generate air negative pressure in the sealed housing, so as to achieve the purpose of attracting debris. However, the existing vacuum cleaners have some shortcomings and certain limitations. First, the noise is too large, which affects the user experience and the life and work of the surrounding people. Bacteria and insects, three, the vacuum effect is easily weakened, but high-power electrical appliances consume a lot of electricity, which is not conducive to long-term use, and four cannot be used for secondary filtration, the dust is too large dur...
