Description
Technical field
This utility model relates to a kind of deafener, the muffler structure of a kind of environment-friendly type.
Background technology
Garden instrument refers to the instrument for aspects such as gardens.Classifying according to use occasion, garden instrument includes garden tool set and garden instrument.According to using object classification, additionally it is possible to be divided into household appliance and professional tool.Different according to power, it is divided into again engine class and electronic class, engine class (gardens gasoline engine) to use 2 strokes or 4 Stroke Engine；Electronic class is subdivided into exchanging class and direct current class.
Wherein be suitable for the most extensive with gardens gasoline engine, at present, international market is more and more higher to the performance requirement of gardens gasoline engine, particularly to environmental conservation, the requirement of security regulations.If it is high to solve deafener surface temperature, the problem that noise is big, then, just can meet the requirement of environmental protection and safety.
Utility model content
The purpose of this utility model is to provide the muffler structure of a kind of environment-friendly type, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of muffler structure of environment-friendly type, including deafener lower cover, asbestos layer, honeycomb catalyst, deafener cover plate and current limliting dividing plate, the sealed bottom joint noise reduction device cover plate of described deafener lower cover, to form muffler shell, and the top center of deafener lower cover offers air inlet, steam vent is offered on deafener cover plate, the middle part of described deafener lower cover arranges current limliting dividing plate, muffler shell inner space is divided into one-level silencing cavity and two grades of silencing cavity by current limliting dividing plate, fixing connection honeycomb catalyst at the middle through-hole of current limliting dividing plate, through hole connection one-level silencing cavity in honeycomb catalyst and two grades of silencing cavity, composite joint asbestos layer on the inwall of described one-level silencing cavity.
As further program of the utility model: described two grades of silencing cavity be arranged in parallel two-layer deafener thermal insulation board, and several through holes are offered on deafener thermal insulation board surface.
As further program of the utility model: offer the through hole identical with steam vent size on the deafener thermal insulation board of steam vent in described two grades of silencing cavity.
As further program of the utility model: described steam vent interlocks with the position of honeycomb catalyst.
As further program of the utility model: arrange gas outlet cover plate outside described steam vent, gas outlet cover plate is fixedly connected on deafener cover plate.
Compared with prior art, the beneficial effects of the utility model are: this practicality arranges asbestos layer on deafener inwall, then can realize the use demand that deafener temperature is low, noise is little.This utility structure is simple and environmentally-friendly, novel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of muffler structure of environment-friendly type, including deafener lower cover 1, asbestos layer 2, gas outlet cover plate 3, honeycomb catalyst 4, deafener thermal insulation board 5, deafener cover plate 6 and current limliting dividing plate 7, the sealed bottom joint noise reduction device cover plate 6 of described deafener lower cover 1, to form muffler shell, and the top center of deafener lower cover 1 offers air inlet, and steam vent offered by deafener cover plate 6.
The middle part of described deafener lower cover 1 arranges current limliting dividing plate 7, muffler shell inner space is divided into one-level silencing cavity and two grades of silencing cavity by current limliting dividing plate 7, fixing connection honeycomb catalyst 4 at the middle through-hole of current limliting dividing plate 7, through hole connection one-level silencing cavity in honeycomb catalyst 4 and two grades of silencing cavity, waste gas makes internal contamination thing and toxic gas be adsorbed by honeycomb catalyst 4, thus discharges clean air.
Composite joint asbestos layer 2 on the inwall of described one-level silencing cavity, is incubated by asbestos layer 2 and absorbs vibrations, so that the surface temperature of muffler shell reduces, simultaneously works as the effect of sound insulation so that the kinetic energy of air-flow is reduced in one-level silencing cavity.
Described two grades of silencing cavity be arranged in parallel two-layer deafener thermal insulation board 5, and deafener thermal insulation board 5 surface is offered several through holes, utilized through hole buffer gas flow.
On the deafener thermal insulation board 5 of steam vent, offer the through hole identical with steam vent size in described two grades of silencing cavity, and steam vent is staggered with the position of honeycomb catalyst 4, prevent air-flow in the position secondary vibrations of steam vent, make a noise.
Arranging gas outlet cover plate 3 outside described steam vent, gas outlet cover plate 3 is fixedly connected on deafener cover plate 6.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
