Description
Technical field
The utility model relates to the motor car engine field, especially a kind of low noise air-strainer that reduces noise.
?
Background technique
Produce power by air and gasoline mixed combustion during motor car engine work; Because contain impurity such as dust in the air, if without filtration, impurity enters into the movement parts accelerated wear test that engine interior can make motor, and the engine charge pipeline is stopped up, so air must filter before entering motor; The model utility of notification number CN2926551Y, disclose a kind of air filter for automobile, described air-strainer comprises and is shaped as square housing that described housing internal fixation has filter screen, be fixed with filter paper with hot melt adhesive below the described filter screen, be stained with filter cloth below the described filter paper; This air-strainer is loaded on the engine charge pipeline, makes the air that enters into motor obtain filtering, and makes obtain prolonging the working life of motor.Because the air inflow in motor car engine when work is very big, air-flow can produce bigger noise through air-strainer the time, influence the comfort level that automobile is taken, and therefore how to reduce the noise that air-flow produces and become problem demanding prompt solution when the process air-strainer.
The model utility content
The purpose of this utility model is can produce the greatly deficiency of noise at air draught through out-of-date in order to overcome existing air filter for automobile, and a kind of low noise air-strainer that can reduce noise is provided.
Concrete technological scheme of the present utility model is:
A kind of low noise air-strainer comprises loam cake; Be covered with gusset, inlet hole on described, described low noise air-strainer has sound-absorption layer; Described sound-absorption layer size is equal to or less than the size of the inboard end face of loam cake gusset; Described sound-absorption layer is provided with through hole; Described through hole is coaxial with inlet hole, and described through-hole diameter is equal to or greater than the inlet hole diameter, the inboard end face bonding of described sound-absorption layer and loam cake gusset.The low noise air-strainer is provided with sound-absorption layer and the bigger inboard end face bonding of loam cake gusset of area, and the noise that air-flow is produced through air-strainer the time is absorbed by sound-absorption layer and reduces.
As preferably: described low noise air-strainer has back-up coat; Described back-up coat size equals sound-absorption layer, and described back-up coat is provided with grid; Described back-up coat and sound-absorption layer bonding.Described low noise air-strainer has the back-up coat that is provided with grid, has both made low noise air-strainer air inlet position increase one deck filter screen, and the loam cake rigidity of low noise air-strainer is strengthened, and makes because the noise that the loam cake vibration produces is weakened.
As preferably: described sound-absorption layer is an acoustical cotton.Acoustical cotton be a kind ofly have that acoustic absorptivity height, thermal insulation are good, nonflammable, structure closely, the sound absorbing material of premium properties such as drainage performance by force and sound absorption qualities does not descend, form is constant after convenient, harmless, the environmentally safe of form stable, very light in weight, construction safety, odorlessness, water-fast, the water logging; Acoustical cotton is applicable to places such as machine room, piano chamber, meeting room, gymnasium, concert hall, recording studio, expressway baffle-wall, can effectively absorb noise, improves environmental degree of comfort; Acoustical cotton is used for air filter for automobile, can effectively absorbs the noise that air draught produces through air-strainer the time, thereby reduce the noise of automobile integral body, improve the comfort level that automobile is taken.
The beneficial effects of the utility model are:
Described low noise air-strainer is provided with sound-absorption layer and the bigger inboard end face bonding of loam cake gusset of area, and the noise that air-flow is produced through air-strainer the time is absorbed by sound-absorption layer and reduces; Described low noise air-strainer has the back-up coat that is provided with grid, this back-up coat had both made low noise air-strainer air inlet position increase one deck filter screen, the loam cake rigidity of low noise air-strainer is strengthened, made because the noise that the loam cake vibration produces is weakened.Described sound-absorption layer is an acoustical cotton, acoustical cotton be a kind ofly have that acoustic absorptivity height, thermal insulation are good, nonflammable, structure closely, the sound absorbing material of premium properties such as drainage performance by force and sound absorption qualities does not descend, form is constant after convenient, harmless, the environmentally safe of form stable, very light in weight, construction safety, odorlessness, water-fast, the water logging; Acoustical cotton is applicable to places such as machine room, piano chamber, meeting room, gymnasium, concert hall, recording studio, expressway baffle-wall, can effectively absorb noise, improves environmental degree of comfort; Acoustical cotton is used for air filter for automobile, can effectively absorbs the noise that air draught produces through air-strainer the time, thereby reduce the noise of automobile integral body, improve the comfort level that automobile is taken.
