Description
Technical Field
[0001] The utility model relates to the technical field of centrifugal fans, and more specifically, the utility model relates to a purification type centrifugal fan. Background Technique
[0002] The purification type centrifugal fan is a device that combines the principle of a centrifugal fan and the function of air purification. Its main function is to suck air through the power of the centrifugal fan and pass it through the internal filtration system to remove pollutants in the air, such as dust, bacteria, viruses, harmful gases, etc., so as to provide clean and healthy air.
[0003] When a general purification type centrifugal fan is in use, first, the staff turns on the power supply, and the motor inside the centrifugal fan drives the impeller to rotate, thereby sucking in external gas and discharging it from the fan through the impeller passage and the volute. When the gas is discharged from the fan, it will pass through the purification layer to purify the gas. However, since the substances inside the purification layer need to be replaced regularly, generally, the internal substances are replaced, but the replacement of substances is rather troublesome and the replacement time is long. Therefore, it needs to be reformed and optimized. Content of the Utility Model

When the threaded rod 18 moves forward, it will drive the limit plate 19 to move forward on the limit rod 20. When one end of the threaded rod 18 completely penetrates through the inside of the purification layer 14, the rotation of the knob 17 can be stopped at this time.
[0025] By turning the knob 17, the front end of the threaded rod 18 moves forward. When the front end of the threaded rod 18 completely passes through the inside of the purification layer 14, the rotation of the knob 17 can be stopped at this time, thereby fixing the purification layer 14. Compared with the traditional device, by installing the purification layer 14, the device can improve the speed of replacing the purification layer, reduce the time for replacing the purification layer, improve the time for replacing the purification layer, and thus improve the working efficiency of the device.

When the impeller 6 rotates, it will drive the rotation of the connecting frame 7. When the connecting frame 7 rotates, it will drive the rotation of the fixed sleeve 9. When the fixed sleeve 9 rotates, it will drive the rotation of the bracket 10. When the bracket 10 rotates, it will drive the rotation of the brush 11. When the brush 11 rotates, the fine hairs at the bottom of the brush 11 will scrape the dust above the inner wall of the outer shell 3.
[0028] By starting the motor 5 to drive the rotation of the connecting frame 7, thereby driving the rotation of the bracket 10. When the bracket 10 rotates, it will drive the rotation of the brush 11. Thus, the dust above the inner wall of the outer shell 3 can be scraped by the brush 11. Compared with the traditional device, the device rotates the brush 11 inside the outer shell 3 to scrape the dust on the inner wall of the outer shell 3, avoiding too much dust inside the outer shell 3 from affecting the rotation of the impeller 6, and thus improving the working efficiency of the device.
[0029] Among them, the centrifugal mechanism includes a motor 5 fixedly arranged on one side of the motor protection case 4. An impeller 6 is fixedly installed above the transmission shaft of the motor 5. A connecting frame 7 is fixedly installed at the front end of the impeller 6. A fixed frame 8 is fixedly installed on the side of the outer shell 3. The connecting frame 7 is rotatably connected to the fixed frame 8. The fixed sleeve 9 is fixedly sleeved with the connecting frame 7.
[0030] By starting the motor 5, the rotation of the impeller 6 will be driven. The outside air is inhaled through the rotation of the impeller 6 and discharged from the fan through the impeller 6 and the outer shell 3.
[0031] Among them, a purification layer 14 is fixedly installed on the side of the outer shell 3. The purification layer 14 is movably connected to the threaded rod 18.
[0032] The discharged gas can be purified through the purification layer 14, thereby purifying the gas.
[0033] Among them, a collection mechanism is fixedly installed at the bottom of the outer shell 3. The collection mechanism includes a fixed bin 12 fixedly arranged at the bottom of the outer shell 3, and a collection bin 13 is movably installed at the bottom inside the fixed bin 12.
[0034] The dust scraped by the scraping mechanism can be collected through the collection bin 13, and by pulling the fixed bin 12 backward, the dust collected in the fixed bin 12 can be removed.
[0035] Among them, there are two brackets 10 and brushes 11 in the scraping mechanism, and they are evenly distributed on the side of the fixed sleeve 9.
[0036] It can improve the efficiency of scraping the dust above the inner wall of the outer shell 3, thereby improving the working efficiency of the device.
[0037] The working principle and usage process of the present utility model:
[0038] When the staff uses it, the staff first places the purification layer 14 inside the mounting frame 15, and then rotates the knob 17. When the knob 17 rotates, since there is a thread at the connection between the knob 17 and the threaded rod 18, and the movement of the knob 17 is restricted by the baffle 16, and the rotation of the threaded rod 18 is restricted by the limiting rod 20, so as the knob 17 rotates, it will drive the threaded rod 18 to move forward. When the threaded rod 18 moves forward, it will drive the limiting plate 19 to move forward above the limiting rod 20. When one end of the threaded rod 18 completely passes through the inside of the purification layer 14, the rotation of the knob 17 can be stopped at this time.

When the connecting frame 7 rotates, it will drive the fixed sleeve 9 to rotate. When the fixed sleeve 9 rotates, it will drive the bracket 10 to rotate. When the bracket 10 rotates, it will drive the brush 11 to rotate. When the brush 11 rotates, the fine hairs at the bottom of the brush 11 will scrape the dust above the inner wall of the outer shell 3.
