[0027] Reference Figures 1-7 The present invention provides an environmentally friendly gas detection filter structure according to an embodiment of the present invention. The environmentally friendly gas detection filter structure includes a filter canister 1. Multiple limiting grooves 2 are formed on the inner wall of the filter canister 1. Multiple filter screen holders 3 are provided inside the filter canister 1. Multiple limiting blocks 4 are fixedly connected to the outer walls of the multiple filter screen holders 3. Multiple limiting blocks 4 are also provided. A mounting groove 5 is formed on the top of each of the multiple filter screen holders 3. A filter screen 6 is installed inside the mounting groove 5. Multiple telescopic grooves 7 are formed on the inner walls of the multiple filter screen holders 3. The outer walls of the multiple filter screen holders 3 are also provided. The filter is provided with multiple arc-shaped grooves 8. Each of the multiple telescopic grooves 7 has a telescopic plate 10 inside. An arc-shaped plate 9 is fixedly connected to the end of the telescopic plate 10 away from the center of the filter holder 3. Two springs 11 are fixedly connected to the inner wall of the arc-shaped plate 9. When the filter 6 is placed inside the bottom filter holder 3, the multiple arc-shaped plates 9 and the telescopic plates 10 connected to them are all away from the center of the filter holder 3. Multiple limiting blocks 4 connected to the outer wall of the bottom filter holder 3 correspond to the multiple limiting grooves 2, thus lowering the bottom filter... The mesh holder 3 is inserted into the filter canister 1. Since the lower ends of the multiple arc-shaped plates 9 are all inclined, during the process of the mesh holder 3 entering the filter canister 1, the arc-shaped plates 9 are squeezed by the inner wall of the filter canister 1, causing the telescopic plates 10 connected to them to move towards the center of the mesh holder 3. At this time, the multiple telescopic plates 10 are all located at the upper end of the filter screen 6, thus securing the filter screen 6 inside the mesh holder 3 from the upper end. The same operation is performed to insert the middle mesh holder 3 into the filter canister 1, and at this time, the bottom of the middle mesh holder 3 is in contact with the top of the multiple lower support rods 13. This allows multiple filter holders 3 to be layered. When the filter 6 needs to be cleaned, the multiple filter holders 3 are pulled upwards and removed from the filter canister 1 in sequence. After the filter holders 3 are completely removed from the filter canister 1, the multiple springs 11 rebound, causing the arc plate 9 and the telescopic plate 10 to return to their original positions, making it easier to remove the filter 6 from the filter holders 3 and to clean the filter 6. The inner walls of the multiple arc grooves 8 are provided with spring grooves 12, and there are two spring grooves 12 in each case. The other end of the spring 11 is fixedly connected to the inner wall of the spring groove 12.

[0028] In another embodiment of this utility model, please refer to Figure 4 and Figure 5The limiting block 4 is located inside the limiting groove 2. The telescopic groove 7 is connected to the arc groove 8. The lower end of the arc plate 9 is all inclined, so that when the filter screen seat 3 is placed in the filter canister 1, the arc plate 9 can be squeezed by the inner wall of the filter canister 1 and move towards the center of the filter screen seat 3. The top of the multiple limiting blocks 4 in the middle and lower layers are all fixedly connected with support rods 13.

[0029] In another embodiment of this utility model, please refer to 1 and Figure 2 A sealing gasket 14 is installed on the top of the filter tank 1. The inner wall of the sealing gasket 14 is provided with a hollow groove 15. There are multiple hollow grooves 15, and each hollow groove 15 corresponds to a multiple limiting groove 2. A top cover 16 is provided on the top of the filter tank 1. The top cover 16 is fixedly connected to the top of the filter tank 1 by bolts 17.

[0030] In another embodiment of this utility model, please refer to Figure 1 An air intake pipe 18 is fixedly connected to the top of the top cover 16. Two lifting lugs 19 are provided on the top of the top cover 16. An exhaust pipe 20 is fixedly connected to the bottom of the filter canister 1. Multiple support feet 21 are fixedly connected to the bottom of the filter canister 1. Shock-absorbing pads 22 are installed on the bottom of each of the multiple support feet 21.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
