Abstract
The utility model relates to a dust collector with a motor noise-eliminating cover, comprising a housing case and a motor installed in the housing case; and the housing case is provided with an air inlet and an air outlet. The utility model is characterized in that a noise-eliminating cover is positioned in the housing case and covered on the motor; the noise-eliminating cover comprises an inner wall and an outer wall, and a noise-eliminating cavity for air flow passing is formed between the inner and outer walls. Compared with the prior art, the utility model has the following advantages: the noise-eliminating cover is designed by using double walls, and the noise of the motor can be effectively reduced in the noise-eliminating cover between the double walls to avoid transmitting out from the housing case directly, thereby reducing the noise well.
Description
Technical field
The utility model relates to a kind of dust catcher, relates in particular to a kind of dust catcher with motor silencer cover.
Background technology
The air intake structure of dust catcher of the prior art comprises suction port, dirt pocket, motor room and exhaust outlet successively, exhaust outlet is generally lattice structure, be used to prevent that impurity from entering in the dust catcher body, but grid there is no the sound-deadening and noise-reducing function, noise was bigger when therefore conventional cleaners was used, and noise is mainly from motor, and power is big more, and noise is loud more.
For this reason, there are a lot of technical literatures openly to solve the sound-deadening and noise-reducing problem of dust catcher, as the patent No. is Chinese invention patent " the silencer used for dust collector " (Granted publication number: CN1179700C) of ZL02148547.X, this Patent equipment comprises the inner panel and the outside plate of make-up, be provided with silencing cavity in the middle of inner panel behind the make-up and the outside plate, the middle part of described inner panel is for the grid chamber of depression, be evenly equipped with steam vent on every side, and the middle part of described outside plate is evenly equipped with steam vent, is the grid chamber of depression on every side; This device is installed on the exhaust outlet of dust catcher, can reduce the noise that dust catcher sends in use greatly.Similarly also has CN1197511C; Also have and in gas channel, to arrange expansion chambers and acoustical panel is installed is reduced noise, as CN201088542Y, CN100423678Y.
Because of noise mainly from motor, also be a technological approaches directly to the motor noise reduction, see that the patent No. is Chinese utility model patent " motor of dust collector the silencer cover " (Granted publication number: CN2484028Y) of ZL01216892.0, this patent comprises the cover wall and the cover end, be that silencer cover integral body is cylindric, the shape of the shell of the motor behind its inner shape and the foam sound-absorbing material that coats sponge and so on matches, and silencer cover is enclosed within on the motor housing behind the foam sound-absorbing material that coats sponge and so on.Though it is less that this silencer cover is installed the back volume, the noise that motor sends does not obtain efficient buffer, directly discharges housing, so noise reduction is not very desirable.
The utility model content
Technical problem to be solved in the utility model is to provide the less and noise reduction of a kind of installation volume significantly to have the dust catcher of motor silencer cover at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of dust catcher with motor silencer cover, comprise casing and be located at the interior motor of casing, aforesaid casing has air inlet and air outlet, it is characterized in that a silencer cover is positioned at described casing and covers on the described motor, this silencer cover comprises inner and outer wall, forms air feed stream between this inner and outer wall by the noise reduction cavity.
Be filled with quieter material in the described noise reduction cavity.Noise can further obtain buffering and reduce, and quieter material can adopt the noise reduction cotton.
Described noise reduction cavity is tortuous the layout.Prolong the time of staying of air-flow in the noise reduction cavity, fully obtain buffering.
Further, form a plurality of hexagonal exhaust vents on the air outlet of described casing, described exhaust vent is a regular hexagon.The noise dispersion effect is better.
Compared with prior art, advantage of the present utility model is: silencer cover adopts the double wall design, the noise that motor sends can obtain efficient buffer in the noise reduction cavity between double wall, avoid directly going out from casing, reduced noise well, the while compact conformation, the installing space that takies is very little, is convenient to the layout of other parts.
Description of drawings
Fig. 1 is the example structure schematic diagram.
Fig. 2 is the enlarged drawing of exhaust vent among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the dust catcher with motor silencer cover in the present embodiment comprises casing 1 and is located at motor 4 and silencer cover 2 in the casing 1, casing 1 has air inlet 12 and air outlet 11, silencer cover 2 is located on the motor 4, silencer cover 2 comprises inwall 22 and outer wall 21, forms air feed stream between this inwall 22 and the outer wall 21 by the noise reduction cavity, is filled with quieter material 3 in the noise reduction cavity, quieter material 3 adopts the noise reduction cotton, and the noise reduction cavity is tortuous the layout.
As shown in Figure 2, form a plurality of orthohexagonal exhaust vents 111 on the air outlet 11 of casing.
Claims (5)
1, a kind of dust catcher with motor silencer cover, comprise casing and be located at the interior motor of casing, aforesaid casing has air inlet and air outlet, it is characterized in that a silencer cover is positioned at described casing and covers on the described motor, this silencer cover comprises inner and outer wall, forms air feed stream between this inner and outer wall by the noise reduction cavity.
2, the dust catcher with motor silencer cover according to claim 1 is characterized in that being filled with quieter material in the described noise reduction cavity.
3, the dust catcher with motor silencer cover according to claim 1 is characterized in that described noise reduction cavity is tortuous layout.
4,, it is characterized in that forming a plurality of hexagonal exhaust vents on the air outlet of described casing according to the described dust catcher of arbitrary claim in the claim 1 to 3 with motor silencer cover.
5, the dust catcher with motor silencer cover according to claim 4 is characterized in that described exhaust vent is a regular hexagon.
