Detailed Implementation

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a ventilation device with a quick-replaceable filter element is disclosed, comprising a duct 1, an opening 101 on the bottom wall of the duct 1, a fan 2 fixed at one end inside the duct 1, a mounting plate 4 below the opening 101, a slot 41 on the upper surface of the mounting plate 4, a filter element 3 inside the slot 41, the top of the filter element 3 passing through the opening 101 and located inside the duct 1, connecting plates 6 fixed on the lower surface of the duct 1 on both sides of the opening 101, a through groove 42 inside the mounting plate 42, a plug-in assembly 5 connected to the connecting plate 6 inside the through groove 42, an air quality transmitter 7 and a controller 8 installed on the inner side wall of the duct 1, and an alarm light 9 installed on the upper surface of the duct 1.

[0023] Flange plates 10 are fixedly connected to both ends of pipe 1.

[0024] The flange plate 10 facilitates the fixing of the pipe 1 to the ventilation pipe.

[0025] Both the air quality transmitter 7 and the alarm light 9 are electrically connected to the controller 8.

[0026] In this embodiment, the controller 8 is model S7-200, and the air quality transmitter 7 is model RS-MG111-1. The air quality transmitter 7 can monitor the air quality inside the pipeline 1 after being filtered by the filter element 3 in real time. Once the air quality does not meet the standard, the information will be fed back to the controller 8, which will control the alarm light 9 to light up, reminding the staff to replace the filter element 3 in time.

[0027] The outer side wall of the filter element 3 is provided with a sealing gasket, and the two sides and the upper surface of the filter element 3 are attached to the inner wall of the pipeline 1. By arranging the sealing gasket, the sealing between the side of the filter element 3 and the inner wall of the pipeline 1 is ensured, thereby ensuring the filtering effect of the filter element 3 on the passing air.

[0028] Two connecting plates 6 are provided with insertion slots 61 on the adjacent sides, the insertion assembly 5 comprises two vertical plates 51 fixed in the through slot 42, the middle portions of the two vertical plates 51 are penetrated and rotationally connected with screw rods 52 through bearings, the surfaces of the screw rods 52 are rotationally connected with square tubes 53 through threads, the two ends of the through slot 42 are provided with square holes 43, and the two square tubes 53 are respectively clamped into the insertion slots 61.
