Description

Technical Field

[0001] This utility model belongs to the field of air filter technology, and in particular relates to an air filter that is easy to replace with activated carbon. Background Technology

[0002] An air filter is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It delivers purified air with low dust content into the room to ensure the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms. Most existing air purifiers use activated carbon filters fixed with screws. Since the filters need cleaning after a period of use, tools are needed to remove the screws, making the process cumbersome and inefficient. A search revealed patent application number 202420219966.3, which discloses an air filter that facilitates activated carbon replacement. This patent belongs to the field of air filter technology and includes a housing and a filter plate. The top surface of the housing has grooves on both sides. A top plate is fixedly connected to the top of the filter plate, and the top plate is fitted to the sidewall of the groove. The inner bottom wall of the housing has openings on both sides. The lower sidewall of the filter plate is fitted to the sidewall of the opening, and the sidewalls of the filter plate are fitted to the inner sidewall of the housing. Elastic groups are provided in the openings that fit against the bottom wall of the filter plate.

[0003] However, in actual use, the applicant found that when installing the filter plate, one person needs to manually move two rotating blocks to move the rotating blocks away from the top of the through groove, and then another person needs to hold the handle to insert the filter plate into the housing through the through groove. It is not possible for a single person to replace the filter plate, which is not convenient. In view of this, we propose an air filter that is easy to replace activated carbon. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] An air filter with easily replaceable activated carbon includes an air filter box 1 and an activated carbon filter plate 3. An air outlet 11 is provided at the top of the air filter box 1. A fan 2 is fixedly installed on the top of the inner side of the air filter box 1 below the air outlet 11. The fan 2 is prior art and is controlled by an external control switch, which will not be described in detail here. Air inlets 12 are symmetrically provided on both sides of the air filter box 1. A fixed frame 5 is fixedly connected to the bottom of the inner side of the air filter box 1 below the fan 2. L-shaped slides 4 are symmetrically elastically connected to the fixed frame 5 via springs 6. A slide rod 7 is fixedly connected inside the fixed frame 5. The lower ends of the two L-shaped slides 4 are movably sleeved on the slide rod 7. The springs 6 are sleeved on the slide rod 7, and their two ends abut against the two L-shaped slides 4 respectively. A pressure plate bracket 41 is fixedly provided at the upper end of the L-shaped slides 4. U-shaped frames 15 are symmetrically fixedly provided in the air filter box 1 on both sides of the fixed frame 5. A U-shaped frame is fixedly connected to the side of the U-shaped frame 15 closest to the fixed frame 5. The activated carbon filter plate 3 is pressed onto the sealing gasket 8 by the pressure plate bracket 41. The sealing gasket 8 can seal the connection between the U-shaped frame 15 and the activated carbon filter plate 3, so that the air entering the air filter box 1 from the air inlet window 12 can be fully filtered and purified by the activated carbon filter plate 3. The top and bottom of the activated carbon filter plate 3 are respectively attached to the top and bottom of the inner side of the air filter box 1. The front side of the air filter box 1 is provided with a box door 13. The front side of the air filter box 1 between the two U-shaped frames 15 is provided with an operation window 14. The operation window 14 is sealed by the box door 13. By manually squeezing the L-shaped slide 4 inward, the L-shaped slide 4 drives the spring 6 to compress, so that the pressure plate bracket 41 is separated from the activated carbon filter plate 3, and the activated carbon filter plate 3 can be taken out from the inside of the air filter box 1 for quick replacement. The operation is convenient and only one person is needed to complete the replacement of the activated carbon filter plate 3, without the need for two people to operate together.

[0022] Working principle: When in use, fan 2 is powered on and rotates. The rotation of fan 2 creates negative pressure inside the air filter box 1. At this time, outside air can enter the air filter box 1 through the air inlet 12, pass through the activated carbon filter plate 3, and then be discharged through the air outlet 11, thus achieving air filtration and purification. After a period of time, when it is necessary to replace the activated carbon filter plate 3, the box door 13 can be opened, and then the L-shaped slide 4 can be manually squeezed inward. The L-shaped slide 4 will slide along the slide rod 7 to compress the spring 6. At the same time, the L-shaped slide 4 can... Separate the pressure plate bracket 41 from the activated carbon filter plate 3, and the activated carbon filter plate 3 can be pulled out from the inside of the air filter box 1. Then, insert the new activated carbon filter plate 3 into the air filter box 1 between the sealing gasket 8 and the pressure plate bracket 41, and release the L-shaped slide 4. At this time, under the elastic force of the spring 6, the L-shaped slide 4 and the pressure plate bracket 41 can move towards the activated carbon filter plate 3, and the activated carbon filter plate 3 can be pressed tightly onto the sealing gasket 8 by the pressure plate bracket 41. Finally, close the box door 13 to complete the quick replacement of the activated carbon filter plate 3.
