Vacuum cleaner with shock absorption and noise prevention functions

Abstract

The invention discloses a vacuum cleaner with shock absorption and noise prevention functions. The vacuum cleaner with the shock absorption and noise prevention functions comprises a handle, a main body, a dust cup, and a dust collecting plate; the main body comprises a front outer cover, a rear outer cover, a fan box, and a suction fan, the front outer cover is mounted in the upper half of the rear outer cover, the dust cup is mounted in the lower half of the rear outer cover, the fan box is mounted between the front outer cover and the rear outer cover, the suction fan is mounted in the fanbox, sound insulation cotton is arranged between the suction fan and the fan box, the handle is mounted above the rear outer cover, the dust cup is placed under the front outer cover and contacts withthe fan box, the lower part of the dust cup is placed on the rear outer cover, the upper part of the dust cup is connected with the front outer cover in a clamping mode, a shock absorption sealing ring is arranged between the dust cup and the fan box, the dust collecting plate is mounted under the rear outer cover, a ventilation duct is arranged on the rear outer cover, one end of the ventilationduct communicates with the dust collecting plate, and the other end of the ventilation duct communicates with the dust cup. The vacuum cleaner with the shock absorption and noise prevention functionshas the advantages of being high in firmness, good in shock absorption effect, good in sound insulation effect, convenient to assemble and disassemble, and high in safety and reliability.

Description

technical field [0001] The invention relates to the related technical field of household electrical appliances, in particular to a vacuum cleaner with shock-absorbing and noise-proof functions. Background technique [0002] Vacuum cleaners can be divided into vertical, horizontal and portable according to their structure. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, generate air negative pressure in the sealed housing, and absorb dust. Vacuum cleaners are mainly composed of three parts: dust collection, dust collection, and dust filtration, generally including series commutator motors, centrifugal fans, dust filters (bags) and dust collection accessories. The power of a general vacuum cleaner is 400-1000W or higher, and the power of a portable vacuum cleaner is generally 250W or less. The vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impelle...

AI Technical Summary

Problems solved by technology

[0003] When the existing vacuum cleaner is in use, the sound of the exhaust fan is often too loud, resulting in noise pollution; at the same time, the exhaust fan will also have a large sense of vibration, so that the user cannot use the vacuum cleaner for a long time; there is also an existing vacuum cleaner The general design method is a centered distribution structure. When it is disassembled, the vacuum cleaner will often fall apart after the screws are screwed, and the consistency of the vacuum cleaner cannot be guaranteed.
