Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to an air purifier with double electrostatic filters. Background Art

[0002] Air purifiers are household appliances used to purify indoor air. Due to the persistent and uncertain nature of pollutant release in indoor air, using an air purifier to purify indoor air is an internationally recognized method for improving indoor air quality. A large number of air purifiers utilize electrostatic dust collection technology. Currently, electrostatic air purifiers both domestically and internationally utilize a single electrostatic adsorption device. This type of air purifier is only suitable for smaller spaces and is less efficient in larger spaces.

[0003] After searching, the patent document with announcement number CN102698556B discloses an air purifier with dual electrostatic adsorption devices, including a casing, an electrostatic adsorption device, a high-voltage generator, a wind wheel and a filter. An installation box for the electrostatic adsorption device is provided in the casing, and the electrostatic adsorption device is provided with a gripper. The power supply generates high voltage through the high-voltage generator and loads it to the electrostatic adsorption device. The motor drives the wind wheel to allow air to enter the electrostatic adsorption device from the air inlet grille through the filter screen for purification and flow out through the air outlet grille; there are two electrostatic adsorption devices, and the two electrostatic adsorption devices are vertically and stacked up and down in the installation box.

[0004] In the above-mentioned prior art, although the first electrostatic adsorption device and the second electrostatic adsorption device stacked up and down can achieve a good filtering effect on the air, it is relatively troublesome to fix the first electrostatic adsorption device and the second electrostatic adsorption device when they are installed inside the casing. Therefore, an air purifier with dual electrostatic filtration is now proposed. Utility Model Content

[0008] Preferably, the air inlet grille, the air outlet grille and the filter are all arranged in a rectangular shape, and the air inlet grille, the air outlet grille and the filter are all slidably connected to the inner wall of the installation cavity.

[0009] Preferably, a mounting groove is provided at the top of the mounting cavity, the tops of the air inlet grille and the air outlet grille are fixedly connected with a first mounting plate, the top of the filter is fixedly connected with a second mounting plate, the first mounting plate and the second mounting plate are both slidably connected to the inner wall of the mounting groove, the first mounting plate and the second mounting plate are coaxially provided with mounting holes, a threaded groove is provided on one side of the mounting groove, and the internal thread of the threaded groove is connected with a mounting bolt that passes through the mounting hole.

A spring is fixedly connected to one side of the movable plate, and one end of the spring is fixedly connected to the inner wall of the fixing groove. A limiting groove is symmetrically provided on the side of the movable plate away from the spring.

[0011] Preferably, the top and bottom of the fixed groove are fixedly connected to the limiting plate, the limiting plate is slidably connected to the inner wall of the limiting groove, one side of the movable plate is fixedly connected to a fixed block, one end of the fixed block is provided with an inclined surface, the first electrostatic adsorption device and the second electrostatic adsorption device are both provided with a fixed slot on the side close to the fixed block, and the fixed block is slidably connected to the inner wall of the fixed slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] When the device is in use, the first electrostatic adsorption device and the second electrostatic adsorption device are respectively placed into the interior of the installation cavity through the installation handles.

The installation and fixing are performed by the fixed blocks on both sides of the first electrostatic adsorption device and the second electrostatic adsorption device, which is relatively convenient and quick.
