Description

Technical Field

[0001] The utility model relates to the field of air purifiers, in particular to a household intelligent air purifier. Background Art

[0002] A smart home air purifier is a device that purifies the air. Its principle is mainly to create negative pressure through the rotation of the fan to draw the indoor air into the purifier. Particulate pollutants (such as PM2.5), gaseous pollutants (such as formaldehyde, benzene, TOVC), and powders and dust in the air in the indoor air will be intercepted and filtered by these filters when passing through the filters inside the air purifier. Common filters include pre-filters, HEPA filters, and activated carbon adsorption layers. HEPA filters are popular for their efficient particle filtering effect. They can decompose toxic gases and bacteria to achieve the purpose of suppressing air pollution.

[0003] At present, smart home air purifiers are generally equipped with universal wheels at the bottom for easy mobility. However, in order to ensure the stability of the purifier during use, the universal wheels generally need to be locked. The locking of the universal wheels generally requires one to be locked one by one, and the unlocking also requires one to be done one by one. Sometimes it is necessary to bend down for manual operation, which is not convenient to use. In addition, the contact area between the bottom of the roller and the ground is small. Since the roller is round, it generally contacts the ground in line rather than in surface contact. Even after locking, its stability is not good, which can easily cause displacement due to external forces such as scratches.

[0004] Therefore, it is necessary to propose a household intelligent air purification device to solve the above problems. Utility Model Content

[0029] It should be noted that the utility model is a household intelligent air purification device. When the air purifier body 1 needs to be moved during use, the first pedal 4 is stepped on. The first pedal 4 drives the first rack 14 to move downward through the connecting arm 11 and the connecting plate 12. The first rack 14 drives the gear 15 to rotate. The gear 15 drives the first column 18 to move upward through the second rack 16. The first spring 17 is compressed, and the first column 18 drives the sealing needle 23 to rise through the pulling block 21. The lower end of the sealing needle 23 is in contact with the second through hole 1. 9 is separated. Due to the action of the first through hole 13, the plastic suction cup 9 is connected with the outside world, and the internal and external pressures are balanced. As the first column 18 moves upward, the pulling block 21 contacts the upper limiting ring 22, and then the pulling block 21 drives the cylinder 10 and the plastic suction cup 9 to move upward as a whole through the limiting ring 22, so that the plastic suction cup 9 is separated from the ground. In addition, since the first pedal 4 will squeeze the locking block 8 to move when it moves downward, the locking block 8 will move and compress the second spring 27. When the plastic suction cup 9 is separated from the ground, the first pedal 4 will move to the locking block 8. The lower end of the block 8 is moved, and then the second spring 27 is reset. One end of the locking block 8 restricts the first pedal 4, and then the air purifier body 1 can be moved. After moving, the second pedal 5 is stepped on. The second pedal 5 drives the locking block 8 to move again through the inclined surface of the notch 25 to compress the second spring 27, so that one end of the locking block 8 is separated from the top of the first pedal 4. Subsequently, the reset of the first spring 17 will drive the first rack 14 to reset, and the first pedal 4 is driven to reset and rise to the top of the locking block 8. , release the second pedal 5, the locking block 8 is reset, and when the first spring 17 is reset, the first column 18 will drive the sealing needle 23 to move downward through the pulling block 21, and the pulling block 21 will drive the cylinder 10 and the plastic suction cup 9 to move downward as a whole through the limiting ring 22 below, and the lower end of the sealing needle 23 is inserted into the second through hole 19 to seal the plastic suction cup 9. After the plastic suction cup 9 contacts the ground, the internal air will be gradually emptied due to the reverse force of the first spring 17, so that the external pressure is greater than the internal pressure, and then the plastic suction cup 9 is adsorbed.
