[0025] Reference Figure 1-5 , now a building energy-saving ventilator provided by an embodiment of the utility model is described. A building energy-saving ventilator comprises a first shell 1 and a second shell 5 fixedly connected to the front end of the first shell 1, a ventilation component is installed inside the first shell 1, a sliding filter component is installed inside the second shell 5, a brush 10 is slidably installed inside the second shell 5, the brush 10 is located at the front end of the filter component, a driving component for driving the brush 10 to move is fixedly installed on the outer wall of the second shell 5, and an ash storage box 15 is slidably installed at the bottom of the second shell 5. When in use, the utility model is first installed on the wall. When ventilation is required, the ventilation component is started to pump the indoor air to the outdoors. In this process, the indoor dust will enter the utility model together with the air. When the dust enters the utility model, it will be blocked by the filter component. When there is a lot of dust, the driving component is started to drive the brush 10 to move. When the brush 10 moves, the dust on the filter component can be hung and dropped into the ash storage box 15.

[0026] The ventilation assembly includes a mounting frame 2, a first drive motor 3 and a fan 4. The mounting frame 2 is fixedly connected to the interior of the first housing 1, the first drive motor 3 is fixedly installed inside the mounting frame 2, the fan 4 is fixedly installed at the output end of the first drive motor 3, the air outlet end of the fan 4 is located outdoors and the air inlet end is located indoors. When ventilation is required, the first drive motor 3 is started to drive the fan 4 to rotate, so that the indoor air can be sucked into the utility model, and then the air is discharged outdoors.

[0027] The filter assembly includes a fixed frame 6, a filter screen 7 and a handle 8. The fixed frame 6 is slidably mounted inside the second housing 5. The filter screen 7 is fixedly connected inside the fixed frame 6. The handle 8 is fixedly connected to the outer wall of the fixed frame 6. When indoor air enters the device, dust also enters the device along with the air. Then the dust is blocked by the filter screen 7, while the air can pass through the filter screen 7 and be discharged to the outside. After a period of use, when the filter screen 7 needs to be cleaned or replaced, the filter screen 7 can be taken out by the handle 8 for replacement or cleaning.

[0028] The driving assembly includes a mounting block 11, a screw rod 12, a moving block 13 and a second driving motor 14. The outer wall of the second housing 5 is fixedly connected to two mounting blocks 11 distributed up and down. The screw rod 12 is movably installed between the two mounting blocks 11. The moving block 13 is fixedly connected to the outer wall of the brush 10. The inside of the moving block 13 is provided with a screw hole, which corresponds to the screw rod 12. The second driving motor 14 is fixedly installed on the top mounting block 11, and the screw rod 12 is fixedly installed on the output end of the second driving motor 14. When there is a lot of dust on the filter 7 that needs to be cleaned, the second driving motor 14 is started, and the output end of the second driving motor 14 drives the screw rod 12 to rotate. When the screw rod 12 rotates, it drives the brush 10 to slide at the front end of the filter 7 with the cooperation of the moving block 13, so that the dust on the filter 7 can be scraped off.

[0029] A plurality of bolts 16 are fixedly connected to one end of the second housing 5 away from the driving assembly, and nuts 17 are installed on the outer walls of the bolts 16. The fixing frame 6 and the ash storage box 15 are fixed to the inside of the second housing 5 by the bolts 16 and the nuts 17. When in use, the fixing frame 6 and the ash storage box 15 can be fixedly installed to the inside of the second housing 5 by the bolts 16 and the nuts 17. When the filter 7 or the ash storage box 15 needs to be cleaned, the nuts 17 can be removed to clean the fixing frame 6 and the ash storage box 15.

[0030] The front end of the second housing 5 is fixedly connected with a plurality of baffles 9. When in use, when large-volume sundries (such as plastic bags) are sucked into the utility model, the sundries can be blocked by the baffles 9 to prevent the large-volume sundries from entering the utility model.

[0031] Working principle: first install the utility model on the wall. When ventilation is needed, start the first drive motor 3. The output end of the first drive motor 3 drives the fan 4 to rotate, so that the indoor air can be sucked into the utility model, and then the air is transported to the outdoors. The indoor dust will enter the utility model together with the air, and the dust will be blocked by the filter 7, while the air can be discharged to the outdoors through the filter 7; if there is a lot of dust on the filter 7, start the second drive motor 14, and drive the screw rod 12 to rotate with the cooperation of the second drive motor 14. When the screw rod 12 rotates, it drives the brush 10 to slide on the front end of the filter 7 with the cooperation of the moving block 13, so that the dust on the filter 7 can be scraped off into the dust storage box 15.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
