Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example

[0028] Please see Figure 1 - Figure 5 The present invention provides a building ventilation device, comprising: a ventilation shell 1, an outer shell 2, and an inner shell 3;

[0029] Fireproof components are provided on the surface of the outer shell 2. A fan 15 is fixedly connected to one side of the outer shell 2. Multiple duct-type UV lamps 16 are provided at the center of the surface of the ventilation shell 1. A guide is fixedly connected to the inner surface of the ventilation shell 1. A filter frame 17 is provided on one side of the guide.

[0030] The inner wall of the filter frame 17 is fixedly connected with multiple layers of nylon filter screen 20, and the center of the inner wall of the filter frame 17 is provided with multiple layers of activated carbon filter cotton 21. One side of the filter frame 17 is provided with multiple temperature and humidity sensors 24, and one end of the filter frame 17 is provided with a humidifying component.

[0031] The surface of the inner shell 3 is provided with multiple sets of retaining components that cooperate with the retaining frame 23.

[0032] Furthermore, the fireproof components include an isolation opening at the center of the surface of the outer shell 2, a fireproof plate 5 on the inner wall of the isolation opening, multiple adjustment openings on the outer surface of the outer shell 2, an electric telescopic rod fixedly connected to the inner wall of the adjustment opening, a connecting rod 6 fixedly connected to the end face of the electric telescopic rod, and a connecting block 14 fixedly connected to the outer surface of the connecting rod 6.

[0033] Specifically, when a fire occurs inside the building, after the fire alarm inside the building is triggered, the control system causes the electric telescopic rod to drive the connecting rod 6 and the connecting block 14, so that the fireproof plate 5 moves inside the adjustment port, thereby sealing the outer shell 2.

[0034] Furthermore, the flow guide includes a flow guide shell 18, a sealing groove formed on one side of the flow guide shell 18, and an inner wall sealing sheet 19 fixedly connected to the sealing groove.

[0035] One side of the sealing sheet 19 is in contact with the filter frame 17.

[0036] Specifically, the filter frame 17 contacts the sealing sheet 19 to prevent gas from passing through the gap between the filter frame 17 and the sealing sheet 19. In addition, the flow guide shell 18 guides the gas entering the filter frame 17.

[0037] Furthermore, a photocatalytic filter 22 is fixedly connected to the inner surface of the filter frame 17, and a plurality of fluorescent lamps 13 are provided on one side of the photocatalytic filter 22 to cooperate with the photocatalytic filter 22.

[0038] Specifically, multiple fluorescent lamps 13 are used to irradiate the photocatalytic filter 22, and the gas is photocatalyzed through the photocatalytic filter 22.

[0039] Furthermore, the humidification component includes a retaining frame 23 and a water supply chamber opened inside the retaining frame 23. The surface of the water supply chamber is provided with multiple nozzles, and one side of each nozzle is provided with an atomizing plate 8.

[0040] The outer surface of the inner shell 3 is provided with a water inlet pipe 7, and one side of the water supply cavity is provided with a flexible hose that matches the water inlet pipe 7.

[0041] Specifically, when the temperature and humidity sensor 24 detects the humidity of the gas inside the filter frame 17, and the humidity of the gas is lower than the preset value, the external water supply pipe is connected to the water inlet pipe 7, and water is supplied to the nozzle through the water inlet pipe 7, the hose, and the water supply chamber. At the same time, the sprayed water is atomized by the atomizing plate 8 to humidify the gas.

[0042] Furthermore, the retaining element includes a retaining opening 11 formed on the outer surface of the inner shell 3 and a retaining block 9 that engages with the inner wall of the retaining opening 11.

[0043] Specifically, the retaining block 9 is inserted into the retaining port 11 to fix the retaining frame 23. When it is necessary to disassemble the filter frame 17, the retaining block 9 is pulled upward to deform and disengage from the retaining port 11, thereby removing the retaining frame 23 and the filter frame 17.

[0044] Furthermore, multiple dustproof blades 12 are fixedly connected to the inner surface of the outer shell 2, a dustproof net 10 is provided at one end of the holding frame 23, and multiple mounting holes 4 are opened on the surface of the inner shell 3.

[0045] Specifically, the dustproof blades 12 prevent external birds from entering the ventilation shell 1, and the expansion bolts pass through the mounting holes 4 to fix the inner shell 3. In addition, the dustproof blades 12 prevent indoor dust from entering the ventilation shell 1.

[0046] The workflow of this application:

[0047] External gas is drawn into the ventilation housing 1 through the outer casing 2 by the fan 15. The gas entering the central part of the ventilation housing 1 is sterilized by multiple duct-type UV lamps 16. The gas is guided by the guide shell 18 and enters the filter frame 17. Dust in the gas is filtered by the nylon filter screen 20. Then, harmful substances in the gas are filtered by the activated carbon filter cotton 21. Finally, the photocatalytic filter screen 22 is irradiated by multiple fluorescent lamps 13 and photocatalytically treated by the photocatalytic filter screen 22.

[0048] When the temperature and humidity sensor 24 detects the humidity of the gas inside the filter frame 17, when the humidity of the gas is lower than the preset value, the external water supply pipe is connected to the water inlet pipe 7, and water is supplied to the nozzle through the water inlet pipe 7, the hose and the water supply chamber. At the same time, the sprayed water is atomized by the atomizing plate 8 to humidify the gas.

[0049] The retaining block 9 is inserted into the retaining port 11 to fix the retaining frame 23. When it is necessary to disassemble the filter frame 17, the retaining block 9 is pulled upward to deform and disengage from the retaining port 11, so that the retaining frame 23 and the filter frame 17 can be removed.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
