Description

Noise reduction structure of dust collector

Technical Field

The utility model relates to a dust catcher technical field especially relates to dust catcher fall the structure of making an uproar.

Background

Because the dust collector uses the miniature ultra-high-speed motor as a power source, great noise can be generated in the using process, the noise at the maximum gear even exceeds 80dB (A) (decibel), and great influence is generated on the hearing of people. The utility model discloses an acoustic sponge of unique structure places in the dust catcher air outlet to cyclic annular guard dust catcher motor can the effectual noise that reduces the dust catcher in the use.

SUMMERY OF THE UTILITY MODEL

In order to reduce the noise of dust catcher, the utility model provides a through place sound absorbing material noise absorption at the inside specific position of dust catcher, the air-out position at the drive fan of dust catcher is one of the fastest position of the air current velocity of flow, and wind is made an uproar very big, consequently increases sound absorbing material and can effectively absorb wind at this position and make an uproar. The utility model provides a technical scheme that above-mentioned technical problem adopted does:

the utility model provides a structure of making an uproar falls in dust catcher, includes air intake, driving fan subassembly, filter screen subassembly, air outlet, the air intake passes through inlet air channel with driving fan subassembly and is connected, the air outlet passes through the air outlet with driving fan subassembly and is connected the air outlet front end installation the filter screen subassembly inhales the sound sponge in air-out passageway position installation, it is arcuation spatial structure to inhale the sound sponge.

The utility model discloses a another technical scheme is on above-mentioned technical scheme's basis, inhales the sound sponge including the first portion and the second portion that link into an integrated entity, the middle lower part of first portion is equipped with opening one, be equipped with opening two in the middle of the second portion, opening one with the central line coincidence of opening two, the radial width of first portion is greater than the radial width of second portion is greater than

The utility model discloses a another technical scheme is on above-mentioned technical scheme's basis, inhales the cyclic annular interval distribution of sound sponge and puts at the air-out passageway.

The utility model discloses a another technical scheme is on above-mentioned technical scheme's basis, inhales the cyclic annular interval of sound sponge and divides 3 equal distributions in the air-out passageway.

The other technical proposal of the utility model is that on the basis of the technical proposal, the air inlet is positioned on the side wall of the dust collector.

The other technical proposal of the utility model is that on the basis of the technical proposal, the air outlet is positioned at the top of the dust collector.

The technical scheme of the utility model the positive effect that produces as follows:

the noise of dust catcher during operation is effectively reduced, does not influence the performance of dust catcher simultaneously, when guaranteeing the quick operation of dust catcher motor, does not influence dust catcher suction, improves the user and uses the comfort.
