Indoor environmental pollutants and pollution sources mainly include radioactive gases, mold, particulate matter, decoration residues, secondhand smoke, etc.

[0003] Existing air purification devices tend to draw in purified air multiple times in a short period of time, resulting in low working efficiency of the device. In addition, after the air purification device has been used for a period of time, a large amount of dust will be accumulated inside the bottom and on the surface of the fan that draws air. Existing air purification devices are difficult to clean the dust automatically, and the cleaning workload for later users is large. Utility Model Content

The device can efficiently remove dust from the air, and can also remove dust from the bottom of the chassis and the surface of the fan and collect the dust, thereby reducing the workload of later users in cleaning the chassis.

[0005] The purpose and effect of the utility model are achieved by the following specific technical means:

[0006] An air purification device comprises a chassis, a cover and a fan, wherein the cover is embedded in the top of the chassis, and the fan is installed at the lower part of the chassis;

DETAILED DESCRIPTION

[0022] See also Figure 1-3 , the embodiments of the utility model are further described;

[0023] An air purification device comprises a chassis 1, a cover 2 and a fan 11, wherein the cover 2 is embedded in the top of the chassis 1, and the fan 11 is installed at the lower part of the chassis 1;

[0024] The outer wall of the chassis 1 and the top of the cover 2 are provided with mounting openings 3, and the mounting openings 3 are embedded with screens 4, and an air guide component is installed between the inner wall of the cover 2 and the air outlet of the fan 11, and an air purification component for air filtering and purification is detachably connected in the air guide component;

[0025] When the device is used, the fan 11 is powered on, and suction is generated around the outside of the fan 11. Figure 2As shown, the air around the outside of the case 1 can be drawn into the inside through the screen 4 to form an airflow. The screen 4 can perform a preliminary filtration on the air to filter out impurities and larger dust particles in the air. Then the air after the preliminary filtration is drawn into the fan 11, and then the airflow discharged through the air outlet of the fan 11 will enter the air guide component. The airflow is gradually guided from the lower part of the inside of the case 1 to the upper part of the inside. The arrangement of the air guide component facilitates the guidance of the airflow in the case 1, and can prevent the air filtered and purified by the air purification component from diffusing to the surroundings of the inside of the case 1, thereby preventing the filtered and purified air from being sucked in multiple times and reducing the working efficiency of the device. Efficiency. In this process, the air purification component can filter and purify the air. When the air flow rises, the dust it carries needs to overcome gravity. As a result, the air purification component is easier to filter and remove dust from the air flow. This design is conducive to the device to efficiently remove dust from the air. The air flow filtered and purified by the air purification component will pass through the screen 4 on the cover 2 and re-enter the environment. In the real environment, the air close to the ground usually has a large amount of dust. The device can draw in the air close to the ground, and the exhausted fresh air will gradually float to the air above the room to prevent the just-treated air from being drawn in by the device again, thereby indirectly improving the efficiency of the device in purifying the air.

[0026] A through hole 13 is opened at the lower part of the outer wall of the chassis 1, and a dust removal component is sealed and slidably connected in the through hole 13. The dust removal component includes a dust box 12, an exhaust pipe 15, a vacuum pump 16 and a mesh cover 17. The dust box 12 is placed at the bottom of the chassis 1 and is slidably connected to the through hole 13, and the dust box 12 is located below the fan 11. The mesh cover 17 is fixed in the dust box 12, the vacuum pump 16 is fixed in the mesh cover 17, the inner end of the exhaust pipe 15 is fixed to the exhaust end of the vacuum pump 16 and communicates with it, and the outer end passes through the mesh cover 17 and the dust box 12.

[0027] After the device has been used for a period of time, the interior and the surface of the fan 11 will contain a lot of dust. At this time, the vacuum pump 16 is powered on. When the vacuum pump 16 is working, it will draw the air in the dust box 12, and then the air in the interior and below the chassis 1 will also be drawn into the dust box 12. While the air is flowing, it will cause the dust in the interior and below the chassis 1 and on the surface of the fan 11 to be carried into the dust box 12, and the dust box 12 will collect the dust, thereby removing the dust in the interior and below the chassis 1 and on the surface of the fan 11 and collecting the dust, which can reduce the workload of users cleaning the chassis 1 in the later stage; under the suction force of the vacuum pump 16, the air in the dust box 12 will pass through the mesh cover 17 and enter the vacuum pump 16. In this process, the mesh cover 17 can filter the air and remove the dust in the air to prevent the dust from clogging the inside of the vacuum pump 16, and finally the air is discharged into the environment through the exhaust pipe 15.

[0028] The air guide assembly includes a cover 5 and an air guide duct 6. The cover 5 is fixed to the inner wall of the cover 2 and surrounds the screen 4 thereon. The air guide duct 6 is embedded between the cover 5 and the air outlet of the fan 11 and the three are connected. The air purification assembly is detachably connected between the cover 5 and the inside of the air guide duct 6.

[0029] Specifically, the arrangement of the cover 5 and the air duct 6 facilitates the guidance of the airflow within the chassis 1 and can prevent the air filtered and purified by the air purification component from diffusing to the surroundings of the interior of the chassis 1, thereby preventing the filtered and purified air from being sucked in multiple times and reducing the working efficiency of the device.

[0030] The air purification component includes an activated carbon screen 7, an upper filter screen 8 and a lower filter screen 9. The activated carbon screen 7 is embedded in the cover 5. The upper filter screen 8 and the lower filter screen 9 are distributed up and down and are both embedded in the air duct 6. The mesh diameter of the upper filter screen 8 is smaller than the mesh diameter of the lower filter screen 9.

[0031] Specifically, after the airflow enters the air duct 6, it will pass through the lower filter 9, the upper filter 8 and the activated carbon mesh plate 7 in sequence. Since the mesh diameter of the upper filter 8 is smaller than the mesh diameter of the lower filter 9, the upper filter 8 and the lower filter 9 can perform double filtering on the airflow, thereby enhancing the air dust removal effect. The activated carbon mesh plate 7 can absorb odors and pigments in the airflow, purify the airflow, and make the discharged fresh air fresher.

[0032] A filter is embedded in the outer end of the exhaust pipe 15. The filter is provided to prevent the outside air from directly carrying dust into the exhaust pipe 15, thereby preventing the exhaust pipe 15 from being blocked by dust.

[0033] A shock-absorbing bracket 10 is fixed in the chassis 1, and the fan 11 is installed on the shock-absorbing bracket 10. The shock-absorbing bracket 10 has a shock-absorbing effect, and can buffer the vibration force generated by the fan 11 when it is working, thereby reducing abnormal noise.

[0034] The chassis 1 is provided with a wind force adjusting knob 14 for adjusting the wind force of the fan 11. When the wind force of the fan 11 needs to be adjusted, the wind force of the fan 11 can be adjusted by rotating the wind force adjusting knob 14 clockwise or counterclockwise to meet the actual needs of the user.
