The utility model supports the placement plate by providing a buffer spring. When the device body prevents the top end of the placement plate from being placed, the transmission rod is rotated to engage the protrusion with the groove, driving the movable plate to move, so that the movable plate drives the clamping block to fix the device body. When shaking, the buffer spring can provide buffering, reducing the shaking of the device body caused by uneven road surface.

[0004] The adsorption capacity of activated carbon fiber is limited. As the usage time increases, it will gradually reach an adsorption saturation state. When saturated, its ability to remove pollutants will drop significantly, and it will no longer be able to effectively purify media such as air or water. The existing activated carbon fiber composite filter is extremely inconvenient to disassemble and use, resulting in low replacement efficiency. Utility Model Content

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-7 An activated carbon fiber composite filter is shown, comprising a filter body 1, the top of the filter body 1 being detachably connected to a sealing cover 11 by bolts, an air inlet 2 being provided at the bottom of the filter body 1, an air outlet 3 being provided at a position near the top of the side wall of the filter body 1, an outer shell 9 being detachably connected to the inner wall of the filter body 1, a bracket 6 being fixedly connected to the inner wall of the filter body 1, and the outer shell 9 being placed on the bracket 6, a card plate 8 being installed at the top of the outer shell 9, and a sealing layer 7 being installed on the surface of the end where the bracket 6 and the card plate 8 are close to each other, an activated carbon fiber filter screen 10 and a pre-filter screen 17 being detachably connected at the upper and lower ends of the outer shell 9, respectively, and two sets of limiting mechanisms being symmetrically provided at the upper and lower ends of the inner wall of the outer shell 9, the limiting mechanisms comprising an annular spacer equidistantly provided at the bottom. A first card slot 14 is formed on the inner wall of the housing 9, and a second card slot 21 is symmetrically formed on the inner wall of the first card slot 14. The side walls of the activated carbon fiber filter 10 and the pre-filter 17 are fixedly connected with a first card block 16 corresponding to the first card slot 14, and the first card block 16 is engaged with the first card slot 14. A first slide groove 19 is symmetrically formed on the side wall of the first card block 16, and a second card block 20 is slidably connected in the first slide groove 19. The two second card blocks 20 are fixedly connected with a magnetic block 22 at one end close to each other, and the two magnetic blocks 22 attract each other. A threaded groove 23 is formed on the top of the first card block 16, and a screw 15 is threadedly connected to the inner wall of the threaded groove 23. The bottom of the screw 15 is designed as an inverted cone, and the bottom end of the screw 15 is stuck between the two magnetic blocks 22.

[0027] The heights of the activated carbon fiber filter 10 and the pre-filter 17 are both less than the depth of the first slot 14 , and the surface of the screw 15 outside the thread groove 23 is designed to be tooth-marked.

[0028] Working principle: When replacing the filter layer of the outer shell 9, the sealing cover 11 can be opened and removed. At this time, the card plate 8 can be taken out first, and then the outer shell 9 can be taken out from the filter body 1. At this time, the screw 15 can be turned to move it upward. When the screw 15 moves to the top position in the thread groove 23 and is stuck with the magnetic block 22, the two second blocks 20 are attracted to each other by the magnetic block 22 and retracted into the first slide groove 19. At this time, the activated carbon fiber filter 10 and the pre-filter 17 can be removed from the first card blocks 16 at both ends of the outer shell 9 from the first card slot 14 for replacement, and the new activated carbon fiber filter 10 is placed in the outer shell 9 so that the first card block 16 is stuck in the first card slot 14. At this time, the second card block 20 is aligned with the second card slot 21, and then Twist the screw 15 in the opposite direction and move it downward until it is fully inserted into the thread groove 23. Push the two second clamping blocks 20 out of the first slide groove 19 and clamp them into the second clamping groove 21, thereby fixing the first clamping groove 14 and the first clamping block 16. After installation, turn the shell 9 over 90 degrees or 180 degrees, and then install the pre-filter 17 at the other end of the shell 9 according to the same steps. After installation, place the replaced shell 9 on the bracket 6 in the filter body 1, and then clamp the clamping plate 8 on the top of the shell 9. At this time, cover the filter body 1 with the sealing cover 11. The sealing cover 11 contacts the clamping plate 8, press the clamping plate 8 and the shell 9 together, and seal the shell 9 and the inner wall of the filter body 1 through the sealing layer 7 to prevent air from not passing through the filtering equipment.

[0029] By providing a limiting mechanism, when the activated carbon fiber filter 10 and the pre-filter 17 are replaced, they can be conveniently disassembled and assembled for quick replacement.

[0030] Second implementation method:

[0031] Figure 2-5 and Figure 8 It is shown that a control panel 4 is fixedly connected to the side wall of the filter body 1, an alarm 5 is installed in the control panel 4, and the control panel 4 is electrically connected to the alarm 5, pressure sensors are installed in the air inlet and the air outlet 3, and the pressure sensors are electrically connected to the control panel 4, an inner groove is opened at the bottom of the first card slot 14, a second compression spring 18 is fixedly connected in the inner groove, and the second compression spring 18 is in conflict with the bottom end of the first card block 16, a groove 24 is symmetrically opened at the top of the shell 9, a second slide groove 25 is symmetrically opened on the inner wall of the groove 24, a handle 13 is slidably connected to the second slide groove 25 through a slider 26, and a first compression spring 12 is symmetrically fixedly connected between the bottom end of the handle 13 and the bottom wall of the groove 24.

[0032] Working principle: When the pressure sensors in the air inlet 2 and the air outlet 3 detect that the pressure difference exceeds the set threshold, the signal is transmitted to the controller, thereby automatically turning on the alarm 5 to remind the staff to replace the activated carbon fiber filter 10 and the pre-filter 17. When the sealing cover 11 is opened and the card plate 8 is taken out, the handle 13 is pushed out of the pop-up groove 24 through the first compression spring 12. At this time, the two handles 13 can be held to pull the outer shell 9 out of the filter body 1. After the outer shell 9 is taken out, the screw 15 is turned to remove the second card block 20 from the second card slot 21. The bottom end of the first card block 16 is pushed by the second compression spring 18 to push the activated carbon fiber filter 10 out of the outer shell 9, and then the pre-filter 17 is also taken out by the same operation.

[0033] The outer shell 9 can be easily taken out from the filter body 1 through the handle 13. After taking it out, the second block 20 and the second slot 21 on the activated carbon fiber filter 10 and the pre-filter 17 are separated, and the second compression spring 18 can be used to push the device out of the outer shell 9 and automatically fall out, avoiding the activated carbon fiber filter 10 and the pre-filter 17 from getting stuck on the inner wall of the outer shell 9 and being difficult to take out.

[0034] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
