[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , an indoor air purification and filtration equipment in this embodiment includes an air purification and filtration equipment body 1, an air inlet filter cover 2 and a protective filter net 3 provided on the air purification and filtration equipment body 1. The inner peripheral wall of the air inlet filter cover 2 is provided with two installation grooves 14, and two support plates 10 are placed inside the two installation grooves 14.

[0024] The right - hand surfaces of the two support plates 10 are fixedly connected with pull plates 9, and the opposite side surfaces of the two support plates 10 are fixedly connected with fixing rods 8. The outer peripheral wall of the protective filter net 3 is provided with two fixing holes 7, and the two fixing rods 8 respectively extend into the two fixing holes 7.

[0025] Among them, the two installation grooves 14 are symmetrically distributed before and after with the protective filter net 3 as the center, and the two fixing rods 8 are in clearance fit with the two fixing holes 7 respectively.

[0026] Specifically, when the protective filter net 3 is pushed, the protective filter net 3 enters the interior of the air inlet filter cover 2. The fixing rod 8 and the fixing hole 7 are on the same center line, and the fixing rod 8 is inserted into the fixing hole 7. Through the clearance fit between the fixing rod 8 and the fixing hole 7, the protective filter net 3 is fixed.

[0027] In this embodiment, support components are provided inside both of the two installation grooves 14. The support components include telescopic rods 15. The telescopic rods 15 are fixedly connected inside the installation grooves 14. The telescopic rods 15 are fixedly connected to the support plates 10. Springs 16 are sleeved on the outer peripheral walls of the telescopic rods 15 and are fixedly connected to the support plates 10 and the installation grooves 14 respectively. Two connection holes 11 are formed in the left side surfaces of the two support plates 10. Rubber rings 12 are fixedly connected inside the two connection holes 11. Two support rods 13 are fixedly connected inside the installation grooves 14, and one end of each of the two support rods 13 penetrates through the rubber ring 12 and extends into the connection hole 11.

[0028] Among them, the telescopic rod 15 is located between the two support rods 13, and the support rod 13 is in contact with the rubber ring 12.

[0029] Specifically, when the support plate 10 moves, it squeezes the telescopic rod 15 and the spring 16, causing the telescopic rod 15 and the spring 16 to contract, thereby driving the fixed rod 8 to move. Through the contact between the support rod 13 and the rubber ring 12, the support plate 10 is supported, improving the stability of the support plate 10. The fixed rod 8 and the fixed hole 7 are on the same center line. When the pull plate 9 is released, under the action of the spring 16, the fixed rod 8 is pushed back to its original position.

[0030] In this embodiment, a limiting component is provided between the air inlet filter cover 2 and the protective filter net 3. The limiting component includes two limiting plates 6. The two limiting plates 6 are respectively fixedly connected to the top surface and the bottom surface of the protective filter net 3. Two limiting grooves 5 are formed in the inner peripheral wall of the air inlet filter cover 2. The two limiting plates 6 respectively extend into the two limiting grooves 5. Rubber pads 4 are fixedly connected to the front and back surfaces of the two limiting plates 6.

[0031] Among them, the limiting plate 6 is slidably connected to the limiting groove 5, and the rubber pad 4 is in contact with the limiting groove 5.

[0032] Specifically, when the protective filter net 3 is pushed, the protective filter net 3 enters the inside of the air inlet filter cover 2, and the limiting plate 6 is inserted into the limiting groove 5 to limit the protective filter net 3. Through the contact between the rubber pad 4 and the limiting groove 5, the protective filter net 3 is supported, improving the stability of the protective filter net 3.

[0033] The working principle of the above embodiment is as follows:

[0034] Pull the pull plate 9 to drive the support plate 10 to move, squeeze the telescopic rod 15 and the spring 16, cause the telescopic rod 15 and the spring 16 to contract, and then drive the fixed rod 8 to move. Through the fitting between the support rod 13 and the rubber ring 12, support the support plate 10 to improve the stability of the support plate 10. Push the protective filter screen 3, and the protective filter screen 3 enters the inside of the air inlet filter cover 2. The limiting plate 6 is inserted into the limiting groove 5 to limit the protective filter screen 3. Through the fitting between the rubber pad 4 and the limiting groove 5, support the protective filter screen 3 to improve the stability of the protective filter screen 3. The fixed rod 8 and the fixing hole 7 are on the same center line. Loosen the pull plate 9, and under the action of the spring 16, push the fixed rod 8 to reset. The fixed rod 8 is inserted into the fixing hole 7. Through the clearance fit between the fixed rod 8 and the fixing hole 7, fix the protective filter screen 3.
