Description
Technical field
The utility model relates to a kind of noise reduction screen pipe of household electrical appliances.
Background technology
Air-conditioning, for the adjustment of air, refers to and uses artificial means, building or the parameter such as temperature, humidity, cleanliness factor of structures environment air is carried out to the process of regulation and control.Air-conditioning in the course of the work, owing to can produce friction between cold-producing medium and refrigerator pipes inside, thus can produce sound in its course of work, affect the life of people.At present, in order to solve the problem, be provided with noise reduction screen pipe in air-conditioning, for eliminating refrigerator sound produced in the course of the work, but the erasure effect of existing noise reduction screen pipe to mechanical sounds is poor, complex structure.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of structure simple, the noise reduction screen pipe of good filtration effect, housing and cavity are adopted conical or cylindrical or taper polyhedron body can reduce refrigerator and air-conditioning work effectively time the noise that produces; Fill silencing cotton between the space simultaneously between housing and cavity, further can carry out noise reduction to the noise produced when refrigerator and air-conditioning work, improve noise dampening efficiency; Housing stiff end and housing adopt the compacting of corronil high temperature obtained, thus strengthen heat-resisting quantity and the corrosion resistance of noise reduction wave filter.
The purpose of this utility model is achieved through the following technical solutions: noise reduction screen pipe, the cavity that it comprises housing and arranges in the housing, described housing and cavity are conical or cylindrical or taper polyhedron body, be provided with gap, be filled with noise elimination cotton in gap between housing and cavity.
Described cavity runs through whole housing.
Described housing is provided with housing stiff end, and housing stiff end and housing are suppressed obtained by metal alloy high temperature.
Described metal alloy is corronil.
The diameter of described housing and housing stiff end is 0.3mm.
The beneficial effects of the utility model are: housing and cavity are adopted conical or cylindrical or taper polyhedron body can reduce refrigerator and air-conditioning work effectively time the noise that produces; Fill silencing cotton between the space simultaneously between housing and cavity, further can carry out noise reduction to the noise produced when refrigerator and air-conditioning work, improve noise dampening efficiency; Housing stiff end and housing adopt the compacting of corronil high temperature obtained, thus enhance heat-resisting quantity and the corrosion resistance of noise reduction wave filter, and structure is simple, good muffling effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-housing, 2-cavity, 3-silencing cotton, 4-housing stiff end.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, noise reduction screen pipe, it comprises housing 1 and fixing cavity 2 within the case 1, identical with the port diameter of housing 1 between the port of cavity 2, described housing 1 and cavity 2 are conical or cylindrical or taper polyhedron body, be provided with gap between housing 1 and cavity 2, in gap, be filled with noise elimination cotton 3.
Preferably, described cavity 2 runs through whole housing 1.
Preferably, described housing 1 is provided with housing stiff end 4, and housing stiff end 4 and housing 1 are suppressed obtained by metal alloy high temperature.
Preferably, described metal alloy is corronil.
Preferably, the diameter of described housing 1 and housing stiff end is 0.3mm.
In order to the course of work of the present utility model is described, for air-conditioning, the utility model is sleeved on the outside of the refrigerator pipes of air-conditioning, in air-conditioning work process, gas enters into refrigerator pipes by the arrival end of air-conditioning, owing to being filled with cold-producing medium in refrigerator pipes, air enters into refrigerator pipes from the arrival end of air-conditioning, and the cold-producing medium taken away in refrigerator pipes, thus reach refrigeration, due to the air in refrigerator pipes take away cold-producing medium time, can rub with the inwall of refrigerator pipes, thus sound, outside due to refrigerator pipes is set with noise reduction screen pipe, therefore, can effectively the inwall of cold-producing medium and refrigerator pipes be occurred to rub and be sounded and filter, thus reach the effect of noise reduction.
When reality uses, also can between adopt the utility model as refrigerator pipes, by housing stiff end 4, noise reduction screen pipe is arranged in air-conditioning, wherein fill cold-producing medium, in air-conditioning work process, gas enters into refrigerator pipes by the arrival end of air-conditioning, owing to being filled with cold-producing medium in refrigerator pipes, air enters into refrigerator pipes from the arrival end of air-conditioning, and the cold-producing medium taken away in refrigerator pipes, thus reach refrigeration, because refrigerator pipes is the utility model, in process of refrigerastion can effectively by due to the flowing of cold-producing medium in refrigerator pipes and the grating produced filter, thus eliminate the sound that air-conditioning produces due to the friction between cold-producing medium and refrigerator pipes inside in the course of the work.
