Description
Technical Field
[0001] This utility model belongs to the field of ventilation equipment technology, specifically a building energy-saving ventilation device. Background Technology
[0002] Building ventilation is a key aspect of maintaining indoor air quality and ensuring the health and comfort of residents. It mainly achieves indoor ventilation through natural ventilation and mechanical ventilation, expelling stale indoor air and introducing fresh outdoor air.
[0003] Existing mechanical ventilation relies on the rotation of fans. When the blades of the ventilation fan rotate, fresh outdoor air is drawn in through the air inlet and then blown into the room, increasing the indoor air pressure and allowing the fresh air to diffuse indoors. However, long-term observation has revealed that existing mechanical ventilation equipment relies on the fan to keep rotating in order to blow outside air into the room. When there is wind outside, the fan continues to rotate actively, which leads to a waste of electricity.
[0004] Therefore, this utility model provides a building energy-saving ventilation device. Utility Model Content

Detailed Implementation
[0023] 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.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 2As shown in the embodiment of this utility model, a building energy-saving ventilation device includes an outer frame 1; a partition 11 is fixedly connected to the inner side wall of the outer frame 1; a pair of fans 12 are installed inside the outer frame 1; a blower 13 is installed inside the outer frame 1; an energy storage module 14 is fixedly connected inside the outer frame 1; a solar panel 15 is installed on the side wall of the outer frame 1; the energy storage module 14 is electrically connected to the solar panel 15 and the blower 13; multiple protective plates 16 are fixedly connected to the side wall of the outer frame 1; a pair of filters 17 are fixedly connected between the outer frame 1 and the partition 11; during operation, the outer frame 1 is installed on the building wall to connect with the outside, and the solar panel 15 faces the outside. When there is wind outside, it will drive the pair of fans 12 to rotate. The fan 12 can blow air from the outside into the room. When there is no wind outside, the fan 13 can be turned on to blow air into the room, thus bringing fresh air into the room. When the solar panel 15 is exposed to sunlight, it will store the converted electrical energy in the energy storage module 14. The energy storage module 14 can then power the fan 13. With the above structure, the fan 12 and the fan 13 can deliver air into the room when there is wind and the fan 13 can actively deliver air into the room when there is no wind. The combination of the two can reduce the waste of electricity caused by the fan 13 constantly running to ventilate the room. At the same time, the solar panel 15 can convert light energy into electrical energy, which can further save energy.
[0026] like Figures 1 to 4 As shown, a linear motor 2 is fixedly connected to the side wall of the partition 11; a connecting component is provided at the output end of the linear motor 2; a fixed frame 21 is installed on the connecting component; a sliding plate 22 is slidably connected to the middle of the fixed frame 21; a support component is provided on the side wall of the fixed frame 21; a wire brush 23 is fixedly connected to the side wall of the sliding plate 22; during operation, when the airflow enters the room, it will be filtered by the filter screen 17, thereby filtering out some dust or lint impurities in the airflow. Then, the linear motor 2 can be periodically started to drive the fixed frame 21 to move back and forth in the vertical direction. At this time, the fixed frame 21 will drive the sliding plate 22 and the wire brush 23 to move. At this time, the wire brush 23 contacts the surface of the filter screen 17 and can brush it, thereby sweeping away the impurities adhering to the surface of the filter screen 17. Through the above structure, the linear motor 2, the fixed frame 21 and the sliding plate 22 are set up, and the wire brush 23 is used to clean the surface of the filter screen 17 by driving the wire brush 23 through the linear motor 2, so as to reduce the situation where impurities adhere to the surface of the filter screen 17, causing the filter screen 17 to become clogged and affecting the airflow.
[0027] like Figure 3 and Figure 5As shown, the connecting assembly includes a fixing plate 3; the fixing plate 3 is fixedly connected to the output end of the linear motor 2; a locking block 31 is fixedly connected to the side wall of the fixing plate 3; a stud 32 is fixedly connected to the side wall of the locking block 31; a slot 33 is provided in the middle of the fixing frame 21; a threaded sleeve 34 is threadedly connected to the middle of the stud 32; the outer side of the threaded sleeve 34 has an impeller structure; during operation, when connecting the fixing frame 21 to the linear motor 2, the slot 33 can be locked onto the locking block 31, and then the threaded sleeve 34 and the stud 32 can be connected together by threads. At this time, the impeller-like structure of the threaded sleeve 34 can lock the linear motor 2. The fixed frame 21 is fixed to one side of the fixed plate 3, thereby installing the fixed frame 21 on the linear motor 2. When it is necessary to disassemble the fixed frame 21, it can be disengaged from the stud 32 by rotating the screw sleeve 34, and the fixed frame 21 can be removed from the side wall of the fixed plate 3. With the above structure, the fixed plate 3, the locking block 31 and the stud 32 are set up, and the locking groove 33 and the screw sleeve 34 are matched to facilitate the installation of the fixed frame 21 on the linear motor 2, so as to improve the convenience of installing and disassembling the fixed frame 21 and the wire brush 23. At this time, it is convenient to replace and maintain the fixed frame 21, the slide plate 22 and the wire brush 23.
[0028] like Figure 4 As shown, a collection box 4 is fixedly connected to the bottom of the slide plate 22; a drawer box 41 is slidably connected inside the collection box 4; during operation, when the wire brush 23 scrapes off the impurities on the filter screen 17, some impurities will fall downwards. At this time, the collection box 4 and the drawer box 41 are located below the wire brush 23, which can collect the fallen impurities. Then the drawer box 41 can be pulled out to pour out the collected impurities, and then the drawer box 41 can be inserted back into the collection box 4 to reset. Through the above structure, the collection box 4 and the drawer box 41 can facilitate the collection of some of the cleaned impurities, so as to reduce the situation where the cleaned impurities scatter around and cause dirt.
[0029] like Figure 4 As shown, the support assembly includes multiple spring rods 5; the spring rods 5 are fixed to the side wall of the fixed frame 21; the ends of the spring rods 5 are in contact with the slide plate 22; during operation, the slide plate 22 is inserted into the fixed frame 21, at which time the ends of the spring rods 5 are in contact with the slide plate 22. When the fixed frame 21 is installed on the linear motor 2, the wire brush 23 is in contact with the filter screen 17. Then, during the process of rotating the screw sleeve 34 to squeeze the fixed frame 21, the slide plate 22 will squeeze the spring rods 5 into a contracted state. When the wire brush 23 is worn after a long period of use, the spring rods 5 will gradually rebound and push the slide plate 22 and the wire brush 23 towards the filter screen 17. At this time, the wire brush 23 can always be in contact with the surface of the filter screen 17. Through the above structure, the spring rods 5 are connected to the fixed frame 21. The elastic action of the spring rods 5 can push the wire brush 23 towards the filter screen 17, which can reduce the situation where the wire brush 23 is not in contact with the filter screen 17 after wear, thus preventing the filter screen 17 surface from being unable to be cleaned.
[0030] like Figure 2 As shown, a storage box 6 is fixed to the side wall of the protective plate 16; a sponge 61 is placed inside the storage box 6; during operation, aromatherapy essential oil is placed in the storage box 6 and then the sponge 61 is inserted into the storage box 6. At this time, after the essential oil soaks the sponge 61, the aroma will be released from the top of the sponge 61. Then, when the airflow flows into the room, the fragrance can be blown into the room. Through the above structure, the storage box 6 and the sponge 61 are set up, and aromatherapy essential oil is used in conjunction to facilitate the fragrance to be blown into the room, thereby improving the overall functionality of the equipment.
[0031] like Figure 4 As shown, a guide plate 7 is fixed to the top of the collection box 4; the guide plate 7 has an inclined structure; during operation, when impurities fall into the collection box 4 and the drawer box 41, the guide plate 7 contacts the surface of the filter screen 17 and is inclined towards the drawer box 41, which can catch the falling impurities and guide them into the drawer box 41. Through the above structure, the guide plate 7 is set to contact the filter screen 17, which can reduce the situation where impurities fall out from the gap between the collection box 4 and the filter screen 17, thereby improving the stability of impurity collection.
[0032] Working principle: The outer frame 1 is installed on the building wall to connect with the outside, and the solar panel 15 faces the outside. When there is wind outside, it drives a pair of fans 12 to rotate, blowing outside air into the room. When there is no wind outside, the fan 13 can be started to rotate and blow air into the room, thus bringing fresh outside air into the room. When the solar panel 15 is exposed to sunlight, it will convert electrical energy and store it in the energy storage module 14. The energy storage module 14 can then power the fan 13. When the airflow enters the room, it will be filtered by the filter screen 17, thus filtering out some dust or lint impurities in the airflow. Then, the linear motor 2 can be started periodically. The fixed frame 21 moves back and forth vertically, which in turn moves the slide plate 22 and the wire brush 23. The wire brush 23 then contacts the surface of the filter screen 17, brushing away impurities adhering to it. When connecting the fixed frame 21 to the linear motor 2, the slot 33 is engaged with the slot block 31, and then the threaded sleeve 34 and stud 32 are connected by threads. The impeller-like structure of the threaded sleeve 34 fixes the fixed frame 21 to one side of the fixed plate 3, thus mounting the fixed frame 21 onto the linear motor 2. When the fixed frame 21 needs to be disassembled, the threaded sleeve 34 can be rotated to disassemble the stud 32. Once disengaged, the fixing bracket 21 can be removed from the side wall of the fixing plate 3. When the wire brush 23 scrapes off the impurities on the filter screen 17, some impurities will fall downwards. At this time, the collection box 4 and the drawer box 41 are located below the wire brush 23, which can collect the fallen impurities. Then, the drawer box 41 can be pulled out to empty the collected impurities. Then, the drawer box 41 can be inserted back into the collection box 4 to reset it. Insert the slide plate 22 into the fixing bracket 21. At this time, the end of the spring rod 5 contacts the slide plate 22. When the fixing bracket 21 is installed on the linear motor 2, the wire brush 23 contacts the filter screen 17. Then, during the process of rotating the screw sleeve 34 to squeeze the fixing bracket 21, the slide plate 22 will squeeze the spring. When the spring rod 5 is in a retracted state, the wire brush 23 will wear out after a long period of use. At this time, the spring rod 5 will gradually rebound and push the slide plate 22 and the wire brush 23 towards the filter screen 17. This will ensure that the wire brush 23 is always in contact with the surface of the filter screen 17. Place the aromatherapy essential oil into the storage box 6 and then insert the sponge 61 into the storage box 6. When the essential oil soaks the sponge 61, it will release the scent from the top of the sponge 61. Then, when the airflow flows into the room, it can blow the fragrance into the room. When impurities fall into the collection box 4 and the drawer 41, the guide plate 7 will contact the surface of the filter screen 17 and tilt towards the drawer 41 to catch the falling impurities and guide them into the drawer 41.
