Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal devices, and particularly relates to a dust removal device with a sound absorption structure. Background Technique
[0002] The working principle of a vacuum cleaner is that the motor drives the blades to rotate at high speed, generating a negative air pressure in the sealed housing to suck dust debris. It is often used to clean dust on the ground and is a commonly used household appliance for cleaning.
[0003] The common vacuum cleaners currently include the main body of the vacuum cleaner, a motor, and a fan. The fan is arranged on the main body, and the motor is arranged on the fan. When in use, the motor is started, the fan rotates, and the main body starts to suck dust, which is convenient for cleaning the dust on the ground, saving time and effort.
[0004] For the above technical conditions, there is still a defect that the motor will generate noise during operation, but the current vacuum cleaners do not have a noise reduction structure.
[0005] Based on this, the utility model designs a dust removal device with a sound absorption structure to solve the above problems. Content of the Utility Model
[0006] The purpose of the utility model is to provide a dust removal device with a sound absorption structure to solve the above technical problems.
[0007] To achieve the above purpose, the utility model provides the following technical solution: A dust removal device with a sound absorption structure includes the main body of the vacuum cleaner, a motor, and a fan. An installation chamber is arranged on the main body, the fan is arranged in the installation chamber, the motor is arranged on the fan, a sound absorption cover is arranged on the installation chamber, the motor is between the sound absorption cover and the fan, the sound absorption cover includes an outer cover, sound absorption cotton, and an inner cover. The inner cover is detachably arranged on the installation chamber, the sound absorption cotton is fixedly arranged on the inner cover, the outer cover is fixedly arranged on the inner cover, the sound absorption cotton is between the outer cover and the inner cover, and fixing holes are formed on the inner cover, and a plurality of fixing holes are arranged on the inner cover.
[0008] Preferably, a fixing ring is fixedly arranged on the inner cover, a threaded ring is fixedly arranged on the installation chamber, and the fixing ring is threadedly connected to the threaded ring.
[0009] Preferably, anti-slip strips are fixedly arranged on the outer side wall of the fixing ring, and a plurality of anti-slip strips are arranged on the fixing ring.
[0010] Preferably, the fixing holes are hexagonal in shape.
[0011] Preferably, the outer cover is made of a material with good sound insulation effect.
[0012] In summary, the present application has the following beneficial technical effects: When the main body of the vacuum cleaner sucks dust, the motor is started, the fan rotates, and the main body starts to suck dust. The noise generated by the operation of the motor spreads towards the sound-absorbing cover. The noise passes through the inner cover, sound-absorbing cotton, and outer cover of the sound-absorbing cover in sequence. Under the multiple reflections of the fixing holes in the inner cover, the noise is reduced. When passing through the sound-absorbing cotton, the noise is further absorbed by the sound-absorbing cotton, and the noise is further reduced. Finally, the noise passes through the outer cover. Since the outer cover is made of a material with good sound insulation effect, the noise is not easily conducted to the outside. At this time, under the action of the inner cover, sound-absorbing cotton, and outer cover, the volume of the noise conducted to the outside is relatively low, achieving the effect of reducing the noise generated by the motor.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0020] The following will further describe the present application in detail with reference to the attached Figures 1-3 This application will be further described in detail below.
[0021] A dust removal device with a sound-absorbing structure, including the main body 4 of the vacuum cleaner, the motor 10 and the fan 7. An installation chamber 8 is provided on the main body 4. The fan 7 is arranged in the installation chamber 8, the motor 10 is arranged on the fan 7, a sound-absorbing cover is provided on the installation chamber 8, and the motor 10 is between the sound-absorbing cover and the fan 7.
[0022] The sound-absorbing cover includes an outer cover 1, sound-absorbing cotton 5 and an inner cover 11. The sound-absorbing cotton 5 is fixedly arranged on the inner cover 11, the outer cover 1 is fixedly connected to the inner cover 11, the sound-absorbing cotton 5 is between the inner cover 11 and the outer cover 1, the outer side wall of the sound-absorbing cotton 5 abuts against the outer cover 1, and the inner side wall of the sound-absorbing cotton 5 abuts against the inner cover 11.
[0023] A threaded ring 9 is fixedly arranged on the installation chamber 8, a fixing ring 3 is fixedly connected to the inner cover 11, and the fixing ring 3 is threadedly connected to the threaded ring 9, so that the sound-absorbing cover is detachably arranged on the main body 4, facilitating the maintenance of the fan 7 and the motor 10.
[0024] The outer cover 1 is made of a material with good sound insulation effect, further enhancing the sound absorption and noise reduction effects of the sound-absorbing cover and reducing the noise leakage of the motor 10. The fixing holes 6 are in the shape of honeycomb hexagons. The hexagonal shape is similar to a honeycomb structure. When the noise is conducted to the sound-absorbing cotton 5 through the fixing holes 6, the noise is effectively reduced through multiple reflections and interferences of the fixing holes 6.
[0025] Anti-slip strips 2 are fixedly arranged on the outer side wall of the fixing ring 3, and a plurality of anti-slip strips 2 are arranged on the fixing ring 3. When the sound-absorbing cover is installed on the installation chamber 8, the anti-slip strips 2 increase the friction between the fixing ring 3 and the human body, making it not easy to slip during installation and facilitating the installation.
[0026] The implementation principle of this embodiment is as follows: When the main body 4 of the vacuum cleaner sucks dust, the motor 10 is started, the fan 7 rotates, and the main body 4 starts to suck dust. The noise generated by the operation of the motor 10 diffuses towards the sound-absorbing cover. The noise passes through the inner cover 11, the sound-absorbing cotton 5 and the outer cover 1 of the sound-absorbing cover in sequence. Under the multiple reflections of the fixing holes 6 of the inner cover 11, the noise is reduced. When passing through the sound-absorbing cotton 5, the noise is further absorbed by the sound-absorbing cotton 5 and the noise is further reduced. Finally, the noise passes through the outer cover 1. Since the outer cover 1 is made of a material with good sound insulation effect, the noise is not easily conducted to the outside world. At this time, the noise generated by the motor 10 is under the action of the inner cover 11, the sound-absorbing cotton 5 and the outer cover 1, and the noise volume conducted to the outside world is relatively low, achieving the effect of reducing the noise generated by the motor 10.
