[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a fire alarm controller, including a housing 1 of the controller. Two fixing strips 2 are welded to the inside of the housing 1 on both sides. A side plate 3 is installed on one side of the fixing strip 2. A cavity 4 is opened on the inside of the side plate 3. Multiple ventilation holes 5 arranged in a rectangular pattern are opened on both sides of the side plate 3. A filter element is placed inside the cavity 4. Two sets of locking elements are installed between the side plate 3 and the housing 1.

[0024] In addition, the two fixing strips 2 on both sides of the housing 1 can support the housing 1 to improve its strength. The side plate 3 has a cavity 4 to provide space for the filter to move, so that the operator can easily put in or replace the filter. The ventilation holes 5 on both sides of the side plate 3 are located on both sides of the cavity 4, which can facilitate air to pass through the housing 1 for ventilation and heat dissipation. The side plate 3 can be disassembled and installed and fixed by using the locking device, so that the operator can remove the side plate 3 to inspect or replace the electronic components inside the housing 1, and also provide operating space for inspection.

[0025] Specifically, the locking mechanism includes a fixing frame 6 fixedly connected to both ends of the side plate 3. The top of the fixing frame 6 has a plurality of evenly arranged movable cavities 7. The inner side of the movable cavity 7 is slidably connected to a pad 9 for fixing the locking block 8. The top of the pad 9 is fixedly connected to a connecting rod 10. The outer side of the connecting rod 10 is fitted with a spring 101 for pressing the pad 9. The top of the plurality of connecting rods 10 is fixedly connected to a connecting strip 11. Both ends of the housing 1 have a plurality of evenly arranged locking grooves 12. The other side of the fixing strip 2 is fixedly connected to a plurality of evenly arranged fixing posts 16. The other side of the side plate 3 and near both ends have a plurality of evenly arranged fixing grooves 17. The outer side of the fixing posts 16 is fitted with three evenly arranged rubber sleeves 20.

[0026] The fixing bracket 6 is L-shaped. When the side plate 3 is embedded in the inner side of the housing 1 and is in contact with the fixing strip 2, the fixing brackets 6 at both ends of the side plate 3 are embedded on the outer side of both ends of the housing 1. At the same time, the fixing post 16 is inserted into the fixing groove 17 to pre-position the side plate 3. Meanwhile, the multiple rubber sleeves 20 on the outer side of the fixing post 16 undergo elastic deformation and are tightly fitted with the fixing groove 17. The locking groove 12 and the locking block 8 are both right-angled trapezoids. The inclined surface of the locking block 8 is in contact with both ends of the housing 1 and slides. At the same time, the locking block 8 compresses the spring 101 through the pad 9 and continues to push the side plate 3 so that the fixing bracket 6 drives the locking block 8 into the locking groove 12 to lock and fix the side plate 3, thereby improving the convenience and stability of installing and removing the side plate 3.

[0027] More specifically, the filter element includes a moisture-proof pad 13 that is movably connected to the inside of the cavity 4. A filter plate 14 for purifying air is placed on one side of the moisture-proof pad 13, and an adsorption pad 15 for adsorbing moisture and impurity particles is placed on the other side of the filter plate 14. The adsorption pad 15 is filled with adsorption material. A plurality of evenly arranged guide grooves 18 are provided on one side of the moisture-proof pad 13, and a plurality of evenly arranged protrusions 19 are provided on one side of the filter plate 14.

[0028] Furthermore, the moisture-proof pad 13 is mainly made of polyester fiber + PU coating, which can ensure the breathability of the moisture-proof pad 13 and prevent moisture from the air from drying out. It can increase the air contact area and also guide the blocked and accumulated moisture downward. The multiple raised strips 19 on one side of the filter plate 14 can increase the contact area between the filter plate 14 and the air, so that there is a gap between the filter plate 14 and the moisture-proof pad 13. The filter plate 14 filters and purifies the impurity particles in the air, preventing dust or impurity particles in the air from entering the housing 1 and damaging the electronic components. The adsorption material in the adsorption pad 15 is mainly montmorillonite + activated carbon, which can adsorb, dry and purify the moisture and pollutants.

[0029] Working principle: When it is necessary to disassemble the side plate 3 to carry out maintenance work inside the housing 1, pull the connecting bar 11, which will cause the pads 9 at the bottom of the multiple connecting rods 10 to move upward. At this time, the pads 9 will cause the locking post to disengage from the locking groove 12, and at the same time, the pads 9 will squeeze the spring 101. Then, the side plate 3 will be disengaged from the housing 1 through the fixing bracket 6. At this time, the fixing groove 17 on one side of the side plate 3 will disengage from the fixing post 16, and at the same time, the rubber sleeve 20 on the outside of the fixing post 16 will disengage from the fixing groove 17, so that maintenance work can be carried out inside the housing 1.
