Abstract
The utility model relates to a vacuum cleaner silencer, which comprises an upper base and a lower base which are buckled together to form a hollow cavity capable of accommodating a fan, wherein an exhaust outlet which can communicate the hollow cavity with the outside air is arranged on the vacuum cleaner silencer, a retaining wall is also arranged in the hollow cavity, surrounds the fan, extends from the lower base to the upper base, and has a notch, and a baffle is also arranged in the hollow cavity for preventing air from directly flowing to the exhaust outlet from the notch; and the retaining wall separates the hollow cavity into an anechoic chamber, and a plurality of muffling plates are arranged in the anechoic chamber at interval. The utility model is arranged in a vacuum cleaner, and can effectively reduce the working noise of the vacuum cleaner.
Description
Technical field
The utility model relates to a kind of dust catcher, especially the silencing means of dust catcher.
Background technology
The dust catcher of prior art generally includes pedestal, be arranged at the blower fan in the pedestal and be located at the outer lid of this blower fan, form the cavity of ccontaining this blower fan between pedestal and the lid, cavity is connected with outside air by exhaust outlet, the air of discharging from fan outlet directly enters this cavity, pressure in the cavity forces air to discharge dust catcher from exhaust outlet greater than outside air pressure.Yet the noise during owing to blower fan work is very big, and noise is unhinderedly directly discharged dust catcher, influences surrounding environment, further influences the normal live and work of people.Therefore the operating noise that reduces dust catcher is the desirability of reality.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of silencing means of dust catcher, and noise is reduced when making dust catcher work.
The silencing means of this dust catcher, comprise a seat of honour and a seat, this seat of honour and this following the cavity that formation one can ccontaining blower fan that is interlocked, the silencing means of this dust catcher is provided with the exhaust outlet that described cavity is connected with outside air, also be provided with in the described cavity one around this blower fan from described following retaining wall that extends to tool one breach at the described seat of honour, also be provided with a blocks air directly flows to described exhaust outlet from described breach baffle plate in this cavity.
The air that comes out from blower fan flows out through the breach of retaining wall, because the effect of baffle plate, air can not directly flow to exhaust outlet, and through the anechoic chamber, discharge from exhaust outlet again, force air to flow through one section like this than long distance, in this process, sound wave is repeatedly reflected, and noise reduction effect is preferably showed in energy attenuation.
Further, described retaining wall forms an anechoic chamber in described cavity, be interval with a plurality of acoustical panels in this anechoic chamber.
One side of described acoustical panel has big bloop, and another side has a plurality of little bloops.
Adjacent acoustical panel both sides dislocation in the anechoic chamber is arranged.
Also be provided with sponge on the described acoustical panel.
The part of described retaining wall is integrally formed on the described seat of honour, and another part is integrally formed on described following.
Described exhaust outlet is arranged on the described seat of honour.
Description of drawings
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is a stereogram of the present utility model following;
Fig. 3 is a vertical view of the present utility model following; And
Fig. 4 is the stereogram at the seat of honour of the present utility model.
The specific embodiment
Referring to Fig. 1, silencing means 1 of the present utility model is for being looped around the device of blower fan 2 outsides.Comprise a seat of honour 11 and one time seat 12, this seat of honour 11 and this following 12 are interlocked formation around the cavity 100 of blower fan 2, and cavity 100 is surrounded by the ring-side wall 116,126 of the seat of honour 11 with following 12.
Referring to Fig. 2 and Fig. 3, in described following 12 cavity 100, be provided with a retaining wall 123 around blower fan 2, retaining wall 123 has a breach 120, be provided with a baffle plate 124 on these breach 120 next doors, this baffle plate 124 connects described following 12 ring-side wall 126 and retaining wall 123, retaining wall 123 is cut apart cavity 100, forms an anechoic chamber 7 of omiting in the form of a ring.
Referring to Fig. 4, in the 11 lower surface cavitys 100 of the seat of honour, be provided with following 12 corresponding retaining wall 113, breach 110, reach baffle plate 114, the exhaust outlet 118 that communicates with outside air is positioned on the ring-side wall 116 at the seat of honour 11, the breach 110 of retaining wall 113 and exhaust outlet 118 lay respectively at the both sides of baffle plate 114, directly flow to described exhaust outlet 118 with blocks air from described breach 110.
The air that comes out from blower fan 2 is through 110, the 120 mouthfuls of outflows that lack of retaining wall 113,123, because baffle plate 114,124 effect, air can not directly flow to exhaust outlet 118, and through anechoic chamber 7, discharge from exhaust outlet 118 again, force air to flow through one section than long distance like this, in this process, sound wave is repeatedly reflected, noise reduction effect is preferably showed in energy attenuation.
As further improvement, referring to Fig. 2 and Fig. 3, in this anechoic chamber 7, be provided with a plurality of acoustical panels 5, the big bloop 51 of one side tool of acoustical panel 5, the less bloop 52 of another side tool, and the both sides of adjacent acoustical panel 5 size bloop 51,52 dislocation are arranged, not only can absorb more noise, and force air glide path in anechoic chamber 7 tortuous more, the energy of sound wave is further decayed.
The utility model also can be provided with sponge on acoustical panel 5, to reduce noise further.
Retaining wall 113,123 of the present utility model is divided into up and down two parts, and each is wholely set with the seat of honour 11 or following 12.
