Abstract
The invention discloses a noise-reduction air blower, and relates to the field of hardware and electrical equipment. The noise-reduction air blower comprises an air blower shell (1), a handle (2), a motor (3), fan blades (4), a switch (5) and an electric heating element (6), wherein the air blower shell (1) is connected with the handle (2), the motor (3) is arranged in the air blower shell (1), the fan blades (4) are arranged at the shaft end of the motor (3), the switch (5) is arranged on the handle (2), the electric heating element (6) is arranged on an air outlet of the air blower, and a damping material layer (7) is arranged on the inner side, close to the air outlet of the air blower, of the air blower shell (1). The damping material layer (7) is made from polyester fiber material. The polyester fiber damping material is arranged on the air outlet of the air blower. Noise generated by the air blower can be greatly reduced, and the noise-reduction air blower is simple in structure and easy to popularize and use.
Description
Technical field:
The present invention relates to heating or oven dry hair-dryer for a kind of daily life, be specifically related to a kind of noise abatement hair-dryer.
Background technology:
Hair-dryer is mainly used in the dry and shaping of hair, but also can do local desiccation, heating and physiotherapy for aspects such as laboratory, psyciotherapy room and industrial production, art designings, when using hair-dryer, hair-dryer motor internal and fan rotate and can produce very large noise, meeting impact oneself and other people mood, the people who particularly lives in a dormitory, the noise pollution of hair-dryer is more obvious.Summary of the invention:
The object of this invention is to provide a kind of noise abatement hair-dryer, it can overcome the drawback of prior art, and the noise producing when hair-dryer is used absorbs by sound-absorbing material, has greatly reduced noise pollution, and practical value is high.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises blower enclosure 1, handle 2, motor 3, fan blade 4, switch 5, heating 6, blower enclosure 1 and handle 2 join, motor 3 is arranged on the inside of blower enclosure 1, fan blade 4 is arranged on the axle head of motor 3, switch 5 is arranged on handle 2, heating 6 is arranged on the air outlet place of hair-dryer, in the inner side of blower enclosure 1, near hair-dryer air outlet place, is evenly provided with sound-absorbing material layer 7.
Described sound-absorbing material layer 7 is made for Polyester Fibers.
The present invention is when using hair-dryer, open switch 5, motor 3 drives fan blade 4 rotations, by air inlet air amount, to air outlet, discharge, produce noise, it causes the vibration of contiguous air and forms sound wave, and to surrounding, propagate in air dielectric, sound can be propagated to air outlet along with wind direction, when sound touches sound-absorbing material layer 7 surface, an acoustic energy part is reflected, part penetrable material, when some vibration due to sound-absorbing material layer 7 or sound are propagated therein and surrounding medium friction, by acoustic energy, change into heat energy, acoustic energy is depleted, play the effect that reduces noise.
The present invention is provided with polyester fiber sound-absorbing material at the air outlet of hair-dryer, the noise that can make hair-dryer produce greatly reduces, simple in structure, adopting polyester fiber sound-absorbing material is a kind of desirable sound-proof decorative materials, the polyester fiber of its raw material 100%, there is sound-absorbing, environmental protection, fire-retardant, heat insulation, insulation, moistureproof, anti-ly go mouldy, easily dedusting, easily cutting, can parquets, good, the cost performance advantages of higher of easy construction, good stability, impact resistance number, independence, be easy to promote and use.
Accompanying drawing explanation:
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the structural representation of air outlet in the embodiment of the present invention.
The specific embodiment:
Referring to Fig. 1, Fig. 2, this specific embodiment is by the following technical solutions: it comprises blower enclosure 1, handle 2, motor 3, fan blade 4, switch 5, heating 6, blower enclosure 1 and handle 2 join, motor 3 is arranged on the inside of blower enclosure 1, fan blade 4 is arranged on the axle head of motor 3, switch 5 is arranged on handle 2, and heating 6 is arranged on the air outlet place of hair-dryer, in the inner side of blower enclosure 1, near hair-dryer air outlet place, is evenly provided with sound-absorbing material layer 7.
Described sound-absorbing material layer 7 is made for Polyester Fibers.
This specific embodiment is when being used hair-dryer, open switch 5, motor 3 drives fan blade 4 rotations, by air inlet air amount, to air outlet, discharge, produce noise, it causes the vibration of contiguous air and forms sound wave, and to surrounding, propagate in air dielectric, sound can be propagated to air outlet along with wind direction, when sound touches sound-absorbing material layer 7 surface, an acoustic energy part is reflected, part penetrable material, when some vibration due to sound-absorbing material layer 7 or sound are propagated therein and surrounding medium friction, by acoustic energy, change into heat energy, acoustic energy is depleted, play the effect that reduces noise.
This specific embodiment is provided with polyester fiber sound-absorbing material at the air outlet of hair-dryer, the noise that can make hair-dryer produce greatly reduces, simple in structure, adopting polyester fiber sound-absorbing material is a kind of desirable sound-proof decorative materials, the polyester fiber of its raw material 100%, there is sound-absorbing, environmental protection, fire-retardant, heat insulation, insulation, moistureproof, anti-ly go mouldy, easily dedusting, easily cutting, can parquets, good, the cost performance advantages of higher of easy construction, good stability, impact resistance number, independence, be easy to promote and use.
