[0003] Since the speed of the driver is as high as more than 10,000 revolutions when working, it is difficult to make the fan blades very balanced in terms of technology. Any slight imbalance will produce great vibrations, which will cause great noise under the effect of resonance, thus easily causing noise interference to the surrounding environment; when the driver is working, the dust is sucked into the collection bag, and the gas is discharged through the driver shell. Since the discharged gas often contains impurities, it is easy to reduce the cleanliness of the discharged gas when the driver is in use; the driver uses negative pressure to absorb dust, therefore, the air inlet pipe of the driver and the connecting pipe or connecting bag need to be sealed, and the connection of the air inlet pipe of the driver is generally sealed only by a sealing ring, which is easy to wear and thin after a long time, which can easily lead to air leakage at the connection of the air inlet pipe when the driver is in use, affecting the use effect.

The flow ring 202 is located on the outside of the impeller 104, and a noise reduction component 201 is arranged on the outside of the inner guide ring 202. An outer guide ring 2011, an air guide port 2012 and sound-absorbing cotton 2013 are arranged inside the noise reduction component 201. The outer side of the inner guide ring 202 is sleeved with an outer guide ring 2011, and the surface of the outer guide ring 2011 is fixedly connected to the inner wall of the upper wind cover 101. The inner wall at the bottom of the outer guide ring 2011 is tightly fitted with the surface of the inner guide ring 202.

[0026] When in use, the impeller 104 will generate noise when rotating. At this time, the wind entering the lower wind hood 103 needs to pass through the top of the inner guide ring 202 and enter between the inner guide ring 202 and the outer guide ring 2011 under the obstruction of the inner guide ring 202. At this time, the incoming wind can be sound-absorbing and noise-reduced under the action of the sound-absorbing cotton 2013.

[0027] Furthermore, if Figure 4 As shown, a sealing mechanism 3 is provided on the outside of the air inlet pipe 105, and the interior of the sealing mechanism 3 includes a sealing component 301 and a silicone ring 302.

The elastic sleeve 3012 is fixed on the surface of the silicone ring 302, and the inner wall of the elastic sleeve 3012 is fixed with the stretch spring 3013. One end of the stretch spring 3013 is fixedly connected to the surface of the silicone ring 302, and the sealing sleeve 3011 is adhered to the bottom of the elastic sleeve 3012. The structure of the sealing sleeve 3011 is an inverted cone structure, and the surface of the sealing sleeve 3011 is adhered and fixed to the surface of the silicone ring 302.
[0028] When in use, the dust collecting pipe of the vacuum cleaner is connected to the air inlet pipe 105. When connected, since the sealing sleeve 3011 is an inverted cone structure, it is convenient for the pipe to be covered onto the surface of the air inlet pipe 105. At this time, under the action of the extension spring 3013, a thrust can be generated on the elastic sleeve 3012, so that the elastic sleeve 3012 is always close to the inner wall of the dust collecting pipe, and the air inlet pipe 105 and the dust collecting pipe are efficiently sealed, so as to avoid the elastic sleeve 3012 from becoming thinner due to wear and affecting the sealing, so as to realize the efficient sealing function of the driver to the connection between the air inlet pipe 105.
[0029] Furthermore, if Figure 3 As shown, a filter mechanism 4 is provided inside the air inlet pipe 105, and the filter mechanism 4 consists of a filter component 401, a baffle ring 402 and a clamping column 403. A baffle ring 402 is fixed to the inner wall of the air inlet pipe 105, and a clamping column 403 is fixed to the bottom of the baffle ring 402. The filter component 401 is provided below the baffle ring 402. The interior of the filter component 401 includes a hygroscopic layer 4011, a fixing ring 4012 and an activated carbon layer 4013. A fixing ring 4012 is provided below the baffle ring 402, and a clamping groove 4014 is provided on the surface of the fixing ring 4012. The clamping groove 4014 and the clamping column 403 are engaged with each other. The interior of the fixing ring 4012 is adhered with a hygroscopic layer 4011, and the surface of the hygroscopic layer 4011 is adhered with an activated carbon layer 4013. The surface of the activated carbon layer 4013 is adhered and fixed to the surface of the fixing ring 4012.
[0030] Before use, the fixing ring 4012 can be placed on one side of the retaining ring 402 so that the slot 4014 is sleeved onto the outside of the column 403. Then, the fixing ring 4012 is pushed so that the slot 4014 engages with the column 403, thereby fixing the fixing ring 4012. When the driver is in use, the dust inhaled by the driver enters the dust collecting pipe connected to the air inlet pipe 105, and the gas enters the air inlet pipe 105. At this time, the moisture absorbing layer 4011 can absorb moisture from the incoming gas, and the activated carbon layer 4013 can filter and remove impurities from the gas. The filtered gas is then discharged through the air outlet 102 to achieve the driver's filtering function for the exhaust gas.
[0031] Working principle: When in use, first connect the dust collecting pipe of the vacuum cleaner with the air inlet pipe 105. When connecting, since the sealing sleeve 3011 is an inverted cone structure, it is convenient for the pipe to be covered on the surface of the air inlet pipe 105. At this time, under the action of the extension spring 3013, a thrust can be generated on the elastic sleeve 3012, so that the elastic sleeve 3012 is always close to the inner wall of the dust collecting pipe, and the air inlet pipe 105 and the dust collecting pipe are efficiently sealed to avoid the elastic sleeve 3012 from becoming thinner due to wear and affecting the sealing, so as to realize the efficient sealing function of the connection between the driver and the air inlet pipe 105, thereby avoiding the use effect affected by air leakage at the connection of the air inlet pipe 105 when the driver is in use.
[0032] During use, the motor body 1 controls the impeller 104 to rotate, and negative air pressure is generated in the lower wind hood 103 to absorb dust. Noise is generated when the impeller 104 rotates. At this time, the wind entering the lower wind hood 103 needs to pass through the top of the inner guide ring 202 and enter between the inner guide ring 202 and the outer guide ring 2011 under the obstruction of the inner guide ring 202. At this time, the incoming wind can be sound-absorbing and noise-reduced under the action of the sound-absorbing cotton 2013. Then the wind enters between the outer guide ring 2011 and the lower wind hood 103 through the air guide port 2012, and is discharged through the air outlet 102. Under the action of the inner guide ring 202 and the sound-absorbing cotton 2013, the time for the wind to be discharged through the air outlet 102 can be slowed down, and the noise of the wind can be reduced to realize the noise reduction function of the driver, so that the driver is not easy to cause noise interference to the surrounding environment when in use.
[0033] Before use, the fixing ring 4012 can be placed on one side of the retaining ring 402 so that the slot 4014 is sleeved onto the outside of the post 403, and then the fixing ring 4012 is pushed so that the slot 4014 is engaged with the post 403, thereby fixing the fixing ring 4012. When the driver is in use, the dust inhaled by the driver enters the dust collecting pipe connected to the air inlet pipe 105, and the gas enters the air inlet pipe 105. At this time, the moisture absorbing layer 4011 can be used to absorb moisture from the incoming gas, and the activated carbon layer 4013 can be used to filter and remove impurities from the gas. The filtered gas is then discharged through the air outlet 102 to realize the filtering function of the driver on the exhaust gas, thereby improving the cleanliness of the exhaust gas when the driver is in use. At the same time, the noise reduction mechanism 2, the sealing mechanism 3 and the filtering mechanism 4 realize the multi-functions of the driver, and finally complete the use of the driver.
