DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Unless otherwise defined, the up, down, left, right, front, back, etc. directions involved in this document are based on the up, down, left, right, front, back, etc. directions in the figures shown in the present utility model, and are explained here together.

[0023] See also Figure 1-4 The utility model provides a technical solution: a building ventilation device that is convenient for cleaning a filter structure, comprising a ventilation fan 1, a ventilation tube 2, a first mounting plate 3, a filter screen 4, a movable rod 5, a gear 6, a motor 7, a movable wheel 8, a cleaning mechanism 9, a receiving box 10, a second mounting plate 11, an activated carbon filter screen 12, a handle 13, a water tank 14, a water inlet 15, a water pump 16, a first water pipe 17, a second water pipe 18 and a spray mechanism 19;

[0024] When using the building ventilation device, firstly, the working principles of the motor 7 and the water pump 16 are mature technologies in the existing background. Figure 1 The ventilation fan 1 in the ventilation duct 2 conveys air to the ventilation duct 2, and the air is filtered through the filter screen 4 arranged on the first mounting plate 3. When it is necessary to clean the dust on the filter screen 4, the motor 7 is turned on. Under the action of the motor 7, the movable rod 5 fixedly connected to the motor 7 is driven to rotate, thereby driving the gear 6 fixedly connected to the movable rod 5 to rotate, and the gear 6 is meshed and connected with the movable wheel 8, so that the rotation of the gear 6 drives the movable wheel 8 to move up and down. A cleaning mechanism 9 is installed on the right outer surface of the movable wheel 8, so that the movable wheel 8 drives the cleaning mechanism 9 to move up and down, thereby cleaning the dust on the filter screen 4;

[0025] The cleaned dust falls into the receiving box 10. When the dust in the ventilator 2 needs to be taken out, since the receiving box 10 is connected to the ventilator 2 by bolts, the bolts are screwed to remove the receiving box 10, thereby facilitating the removal of the dust.

[0026] The filtered air passes through the activated carbon filter 12 to remove odor. When the activated carbon filter 12 needs to be replaced, the handle 13 is fixedly connected to the second mounting plate 11. The top of the second mounting plate 11 is connected to the slot of the ventilator 2. The activated carbon filter 12 is installed on the second mounting plate 11. Pull the handle 13 to pull out the second mounting plate 11, so as to facilitate the replacement of the activated carbon filter 12.

[0027] When the air after odor removal reaches the air outlet, water is injected into the water tank 14 through the water inlet 15, and the water pump 16 is turned on. Under the action of the water pump 16, water is pumped from the water tank 14 through the first water pipe 17, and the water is transported to the spray mechanism 19 through the second water pipe 18. The spray mechanism 19 sprays the air outlet of the ventilation tube 2 to increase the humidity of the air, thereby completing a complete set of building ventilation equipment.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
