Technical Field

[0001] This utility model belongs to the field of ventilation equipment, specifically relating to an anti-clogging, silent floor blower. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. Simply put, a fan is like a "gas transporter". Through a specific mechanical structure, it draws in air or other gases from one place, pressurizes them, and then transports them to another place.

[0003] In the operation of some existing wind turbines, the motor generates a lot of noise, causing sound pollution to the surrounding environment. It may also cause friction and vibration between the wind turbine and the ground or other components, affecting the stability and service life of the wind turbine. In addition, the wind turbine not only generates wind noise during operation, but also requires the disassembly of multiple components during maintenance, which is cumbersome and time-consuming.

[0004] Therefore, some existing wind turbines suffer from excessive noise, unsatisfactory vibration reduction, and cumbersome maintenance during operation. Utility Model Content

[0022] Please see Figures 1-6This utility model provides an embodiment of an anti-clogging, silent floor blower, including a housing 1; it also includes a snap-fit ​​ring 302 and a target-shaped perforated sound-absorbing frame 307. Air-generating chambers 103 are rigidly connected to the inner walls of both ends of the housing 1. A power component placement slot 102 is provided at the right end of the housing 1 and the air-generating chamber 103, forming an integral structure. A power component is installed in the power component placement slot 102 and the air-generating chamber 103. An exhaust port 1 is provided at the front end of the air-generating chamber 103. 04. A dustproof installation ventilation slot 101 is provided at the front end of the housing 1. A snap-fit ​​ring 302 is fitted onto the arc-shaped inner wall of the dustproof installation ventilation slot 101. A fixing ring 3 is fixedly connected to the left end of the snap-fit ​​ring 302. A first groove 303 is provided through both ends of the fixing ring 3. A dustproof net 301 for dust protection is fixedly connected to the arc-shaped inner wall of the fixing ring 3. A flexible spring 304 for removing the housing is fixedly connected to the inner wall of the snap-fit ​​ring 302. One end of 04 extends through the first groove 303 to the left end of the fixing ring 3. A target-shaped perforated sound-absorbing frame 307 is fixedly connected to the right end of the fixing ring 3. A second sound-absorbing cotton 308 for sound absorption is placed inside the target-shaped perforated sound-absorbing frame 307. An annular sound-absorbing cotton 305 for vibration damping and noise reduction is fixedly connected to the outermost arc-shaped outer wall of the target-shaped perforated sound-absorbing frame 307. A dustproof net 301 is installed on the inner wall of the fixing ring 3, intercepting external floating objects during operation and providing dust protection. One end of the elastic spring 304 extends to the left end through the through hole of the fixing ring 3. During maintenance, pressing it can deform and pull out the buckle ring 302, enabling quick disassembly and convenient cleaning of related parts. The target-shaped perforated sound-absorbing frame 307 is fixed to the right end of the fixing ring 3, and a second sound-absorbing cotton 308 is placed inside. The two work together to absorb and eliminate wind noise. The annular sound-absorbing cotton 305 is fixed to the outermost arc-shaped outer wall of the target-shaped perforated sound-absorbing frame 307, which plays a role in vibration reduction and noise reduction, and reduces the resonance noise of the shell 1.

[0023] Please see Figures 1-4In this embodiment, two second grooves 306 are formed on the annular sound-absorbing cotton 305, and two flexible spring sheets 304 are placed in the second grooves 306. The second grooves 306 provide a placement position for the flexible spring sheets 304, allowing them to be stably installed and ensuring the normal implementation of subsequent pressing operations. The power component includes a servo motor 2. Two arc-shaped rubber strips 204 are fixedly connected to the upper end of the inner wall of the power component placement groove 102, and two mounting blocks 205 are fixedly connected to the lower end of the inner wall of the power component placement groove 102. The servo motor 2 is threaded onto the two mounting blocks 205, and the outer wall of the servo motor 2 and the outer wall of the two arc-shaped rubber strips 204 are in contact with each other. The heat dissipation and dustproof mesh 108 is bolted to the opening of the power component placement groove 102. The mounting blocks 205 provide support for the servo motor 2. A mounting point is provided to ensure that the servo motor 2 can be installed. The heat dissipation and dustproof mesh 108 is used for dust prevention and heat dissipation. The left output shaft of the servo motor 2 is fixedly connected to the rotating shaft 201. The outer wall of the rotating shaft 201 is fixedly connected to the impeller 202. The left end of the rotating shaft 201 is threaded with a locking sleeve 203 for fastening the impeller 202. The target-shaped perforated sound-absorbing frame 307 has evenly distributed holes on its arc surface. The target-shaped perforated sound-absorbing frame 307 is shaped like a target and placed at the right end of the dustproof mesh 301. The axes of the dustproof mesh 301 and the target-shaped perforated sound-absorbing frame 307 are collinear. The holes on the arc surface of the target-shaped perforated sound-absorbing frame 307 facilitate the sound to enter its interior. Combined with the second sound-absorbing cotton 308, it can better eliminate wind noise.

[0024] Please see Figure 1 , Figure 5 and Figure 6 In this embodiment, two vibration-damping second rubber strips 4 are fixedly connected to the lower end of the housing 1, and a vibration-damping rubber pad 5 is fixedly connected to the lower end of the air-generating chamber 103. The lower ends of the two second rubber strips 4 and the rubber pad 5 are flush. A processing chamber 105 is provided at the rear end of the air-generating chamber 103. A Hall effect adjustment knob 106 for adjusting the speed of the servo motor 2 is provided at the rear end of the processing chamber 105. An insertion port 107 is provided at the rear end of the processing chamber 105. The upper end of the housing 1 is connected to a handle in the shape of a grip.

[0025] By connecting the socket 107 to the power supply and then rotating the Hall effect adjustment knob 106, the speed of the servo motor 2 can be adjusted, thereby driving the impeller 202 to rotate in the air-generating chamber 103. Air enters through the dustproof ventilation slot 101 on the housing 1 and is then discharged through the exhaust port 104. When the device is working, the dustproof net 301 installed on the fixing ring 3 first intercepts external stones, dust, and other floating objects. Then, the wind noise behind the dustproof net 301 is absorbed and eliminated by the annular sound-absorbing cotton 305, the target-shaped perforated sound-absorbing frame 307, and the second sound-absorbing cotton 308. The noise is further absorbed by the two arc-shaped rubber rods. The clamping of the rubber strip 204 reduces the noise caused by the vibration of the servo motor 2 causing the housing 1 to resonate. At the same time, the rubber pad 5 and the second rubber strip 4 can also reduce the frictional vibration between the lower end of the housing 1 and the ground during operation. When performing maintenance, by pressing the two flexible springs 304 close to the axis of the fixing ring 3, the outer wall of the buckle ring 302 can be deformed at the contact point with the inner wall of the dustproof installation ventilation slot 101, thereby pulling the buckle ring 302 out of the dustproof installation ventilation slot 101, and quickly cleaning the dustproof mesh 301 and the built-in sound-absorbing and noise-reducing components, reducing cumbersome installation and disassembly steps.
