Abstract
The utility model relates to a composite small blower which comprises a motor, a blower blade and a casing. The composite small blower is characterized in that a silencer (3) is arranged on the air inlet part of the blower casing, and a damping layer (7) is coated on the casing. The utility model has the advantages of simple structure, convenience and practicality and can solve the problem of noise production of small blowers at the present days that environment protection needs enhancing.
Description
The utility model relates to the blast apparatus before the stove fire, specifically compound small blower.
1.2 the small blast fan below kilowatt is people live in widely used cooking utensils, army, office, school, service industry, factory etc., every group dining or the big slightly place of cooking workload all need to come air blast to make a fire with it.Owing to the structural reason of small blower, it all can produce 78～92dB (A), even bigger noise.This noise brings adverse influence for people's work, studying and living considerably beyond the regulation of country to ambient noise.Up to now, the blower below 1.2 kilowatts does not all have the noise elimination noise reduction device, this class small blower noise problem be not resolved always.
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of composite structure is provided, and can reduce the compound small blower of noise.
The utility model is achieved in that this compound small blower comprises motor, and fan blade and shell is characterized in that at flow blower casing intake grill place silencing apparatus being housed, and shell scribbles the damping coating.Silencing apparatus can be a disc type.Circular pipe type.Square chest type.Bend muffler.
Below in conjunction with accompanying drawing the utility model is described in further detail, but is not limited to shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Among the figure, 1-motor, 2-flow blower casing, 3-silencing apparatus, 4-fan air inlet, 5-screw, 6-blade, 7-damping coating, 8-muffler material.
As shown in the figure, blower of the present utility model is mainly by motor 1, fan blade 6 and shell 2, and silencing apparatus 3 constitutes, and scribbles damping coating 7 on shell.Silencing apparatus is installed in fan air inlet 4 places and fixing with screw 5.Silencing apparatus inside is muffler material 8 (or using microperforated panel).The use of blower of the present utility model is identical with common small blower, only has the operation that opens and closes circuit.Its working principle is that motor rotates, and drives the fan blade rotation, in air suction casing, the air power noise that produce this moment is absorbed by the sound absorbing material in the silencing apparatus (8), on the other hand, the then damped coating of noise that casing vibration is sent is its vibration weakening, thereby reduced noise.
The utility model is simple in structure, and convenient being suitable for can solve the noise problem that small blower produces.Today strengthening environmental protection, have very strong social demand and good market prospects.
Claims (2)
1, a kind of compound small blower comprises motor, and fan blade and shell is characterized in that at flow blower casing suction port place silencing apparatus (8) being housed, and flow blower casing scribbles damping coating (7).
2, blower according to claim 1 is characterized in that having in the silencing apparatus sound absorbing material or microperforated panel (8), and profile can be a disc type, or circular pipe type, or square chest type, or bend muffler.
