Description

Technical Field

[0001] The utility model relates to the technical field of dust blowers, in particular to a dust blower with a noise reduction mechanism. Background Art

[0002] A dust blower is usually composed of a motor and a fan, which can generate a strong airflow to quickly blow away dust, debris and residue. It can also be used to remove dust from computer cases and keyboards, and clean the gaps between keys in the car. In addition, it can also be used to make fire during outdoor camping.

[0003] When the dust blower is working, it will generate a lot of noise due to vibration, internal medium flow friction, collision and disturbance. The general noise reduction method is to reduce noise through a single sound-absorbing cotton, but the noise reduction effect is not obvious, so it is urgently needed to be improved. Utility Model Content

[0007] A high-speed brushless motor, wherein the high-speed brushless motor is installed inside the soundproof inner cylinder, and a turbo fan is installed at the output end of the high-speed brushless motor;

[0008] A vacuum noise reduction mechanism, wherein the vacuum noise reduction mechanism is arranged between the sound insulation inner cylinder and the dust collector body, and the vacuum noise reduction mechanism comprises a vacuum chamber, a noise reduction ring liner, and a semicircular energy absorption groove. The noise reduction ring liner is adhered to the vacuum chamber between the sound insulation inner cylinder and the dust collector body, and the semicircular energy absorption grooves are distributed on the surface of the noise reduction ring liner.

[0026] The guide plate 601 is a long strip-shaped sheet structure;

[0027] Specifically, when the air flows inside the dust collector body 5, the guide plate 601 on the surface of the soundproof inner cylinder 6 guides the air, changes the disorderly flow state of the airflow, reduces the turbulence of the airflow, and reduces the noise. The sound-absorbing cotton 602 can absorb the noise transmitted to the outside.

[0029] Specifically, the dust blower is mainly composed of a dust blower handle 1, a dust collector body 5, a high-speed brushless motor 10, a turbo fan 11, and an air outlet 3. The high-speed brushless motor 10 drives the turbo fan 11 to rotate at a high speed, so that air enters the dust collector body 5 through the air inlet 502 and enters the air outlet 3 through the air outlet 501 and then blows out;

[0031] Furthermore, since the dust collector body 5 and the soundproof inner cylinder 6 form a vacuum double-layer structure, noise transmission can be blocked. The vacuum noise reduction mechanism 7 is arranged between the dust collector body 5 and the soundproof inner cylinder 6. When a small amount of noise enters the vacuum chamber 701, the noise reduction ring liner 702 and the semicircular energy absorption groove 703 on the surface further absorb and consume the energy.

The high-speed brushless motor 10 drives the turbo fan 11 to rotate at a high speed, so that the air enters the dust collector body 5 through the air inlet 502 and enters the air outlet nozzle 3 through the air outlet 501 and then blows out. When the air flows inside the dust collector body 5, the guide plate 601 on the surface of the soundproof inner tube 6 guides the air, changes the disorderly flow state of the airflow, reduces airflow turbulence, and reduces noise. The sound-absorbing cotton 602 can absorb the noise transmitted to the outside. Furthermore, since the dust collector body 5 and the sound insulation inner cylinder 6 form a vacuum double-layer structure, the noise transmission can be hindered.
