Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Examples

1-4, Please refer to the air filter, including filter layer 2 and be "mouthful" style of calligraphy setting filter frame 1, filter frame 1's inboard surface has been seted up with filter layer 2 assorted inside groove 10, the top and the bottom of inside groove 10 are all fixedly connected with and are "mouthful" style of calligraphy setting sealing strip 12, filter layer 2 one end is pegged graft in inside groove 10 through opening 13, filter frame 1's one end has been seted up with filter layer 2 assorted opening 13, filter layer 2's one end is passed in the inside groove 10 of inserting in filter frame 1 from opening 13, thereby make filter layer 2 connect on filter frame 1 steadily, the opening 13 interpolation has shutoff strip 3, and shutoff strip 3 detachable connection is on filter frame 1, concretely, filter layer 2 can adopt the HEPA filter layer, have higher filtration efficiency.

In an alternative embodiment: both ends of the plugging strip 3 are fixedly connected with a fixing strip 32, both ends of one side, close to the through hole 13, of the filter frame 1 are fixedly connected with a fixing block 11, one end, close to the plugging strip 3, of the fixing block 11 is provided with a middle groove 110, both sides of the middle groove 110 are provided with side grooves 111, and steel balls 113 are fixedly connected in the side grooves 111 through springs 112.

As shown in fig. 2-3, in an alternative embodiment: the fixing grooves 321 matched with the steel balls 113 are formed on two sides of the fixing strip 32, specifically, when the fixing strip 32 is inserted into the middle groove 110, the steel balls 113 in the side grooves 111 are contacted with the fixing grooves 321 on two sides of the fixing strip 32, and the steel balls 113 enter the fixing grooves 321 under the action of the springs 112, so that the fixing strip 32 is fixed in the fixing block 11.
