Description

Technical Field

[0002] Building ventilation equipment is generally installed on the wall of the building for indoor ventilation. It is generally composed of an air duct and a fan on the air duct. A heat exchange device is generally installed inside the air duct to heat the cold air entering the room in winter, keep the room warm and improve the user's comfort. Generally, a heat exchange device uses a heating coil. When the air flows along the passage where the heating coil is installed, the heating coil heats the air. However, there are the following defects: The heating temperature of the heating coil can only be controlled by the remote control to control the input current. When the air intake speed is adjusted to a small value, when the air flows through the heating passage, the amount of air circulating is reduced and the heating time remains unchanged, which can easily cause the temperature of the air blown into the room to increase, causing the temperature of the air blown into the room to rise.

The first side plate 9075 on the side of the power connection block 9071 is located above the second side plate 9078 on the side of the power connection block 9071 close to the first air inlet baffle 5. After the conductive plate 1004 moves toward the heating box 901, the heating strips 903 on the side of the conductive plate 1004 close to the first air inlet baffle 5 can be connected to the circuit. The smaller the air inlet area, the more heating strips 903 are connected to the circuit. The smaller the number, as the movable frame 805 moves and drives the conductive plate 1004 to move to the target position, the heating strips 903 on the side of the conductive plate 1004 close to the first air inlet baffle 5 are connected to the circuit, while the heating strips 903 on the side of the conductive plate 1004 away from the first air inlet baffle 5 are not connected to the circuit, so that the closer the conductive plate 1004 is to the first air inlet baffle 5, the fewer heating strips 903 connected to the circuit, the shorter the heating path length, the shorter the heating length of the air, so that the heating time and the air intake volume are adaptively adjusted to ensure the stability of the air intake temperature, and a side tube 1007 is installed on the side of the movable frame 805 away from the side conductive strip 1001, and the upper and lower sides of the side tube 1007 are provided with connecting grooves 1008, and the inside of the side tube 1007 is movably installed with movable The movable column 1009 is located at one end of the side tube 1007, and the upper and lower sides of the movable column 1009 are hingedly installed with connecting rods 1010.

The friction plate 1018 contacts the axial outer wall of the rotating ring 1014. The rotating ring 1014 on the movable column 1009 contacts the friction plate 1018. When the moving frame 805 moves and adjusts, the rotating ring 1014 rotates continuously under the action of friction, and then continuously generates electricity through the small generator 1017 and passes it into the electromagnet 1012, driving the movable column 1009 to move toward the heating box 901 to drive the two conductive plates 1004 away from each other, so that the power connection and heating are stopped during the movement, ensuring the safety of use and avoiding the wear of the power connection parts during the movement.

[0023] Working principle: when installing the equipment, a mounting slot is preset on the wall, and the air duct 1 is installed inside the mounting slot, so that the air inlet on the air duct 1 is located indoors, and one end of the air duct 1 provided with the fan 4 is located outdoors. During normal use, the solar panel 2 can absorb solar energy, and then convert the solar energy into electrical energy through the energy conversion device and store it inside the battery 3, which is green and energy-saving. When ventilation is performed, the fan 4 is turned on to drive the outside air to pass through the heating box 901 and blow into the room from the air inlet. When the air intake intensity needs to be reduced, the drive motor 802 is turned on to rotate the screw 801. Since the screw 801 is threadedly connected to the moving frame 805, the moving frame 805 is driven to move toward the side of the first air intake baffle 5, thereby generating pressure on the inclined plate 704 through the top rod 807, pushing the upper and lower baffles 703 closer to each other, thereby continuously reducing the air intake port area at the heating box 901, thereby adjusting the air intake intensity; When used in winter, the air intake needs to be heated, the output switch of the battery 3 is turned on, and the heating strip 903 is connected to the circuit through the two side conductive strips 1001, the two connecting posts 1002, and the two conductive plates 1004, so that the heating strip 903 is energized to generate heat to heat the air. At the same time, when the moving frame 805 moves to a predetermined position toward the first air inlet baffle 5, the upper and lower conductive plates 1004 approach each other, and one of the connecting blocks 9071 moves toward the side of the vertical plate 902, so that the second contact 9074 contacts the connecting slot 904, thereby energizing the corresponding heating strip 903. At the same time, due to the first side plate 907 on one side of the connecting block 9071 5 is located above the second side plate 9078 on the side of the power block 9071 near the first air inlet baffle 5, so that after one of the power blocks 9071 is compressed, all the power blocks 9071 near the first air inlet baffle 5 are driven to move toward the side of the vertical plate 902, so that the heating strips 903 located on the side of the conductive plate 1004 near the first air inlet baffle 5 are all connected to the circuit, so that the heating strips 903 are powered on to heat the air, and the smaller the air inlet area is, the closer the distance between the moving frame 805 and the first air inlet baffle 5 is, so that the number of heating strips 903 connected to the circuit is less, the heating length of the air is shorter, and the heating time and the air inlet volume are adaptively adjusted to ensure the stability of the air inlet temperature; When the moving frame 805 is moving, the outer wall of the rotating ring 1014 contacts the friction plate 1018, and the rotating ring 1014 rotates under the action of friction, and then the input shaft of the small generator 1017 is driven to rotate through the gear ring 1015 and the gear 1016, so that the small generator 1017 generates electricity and inputs current into the electromagnet 1012. The electromagnet 1012 is energized to generate an attraction to the magnetic block 1013, pulling the movable column 1009 to move toward one side of the moving frame 805, and then the upper and lower conductive plates 1004 are pushed away from the heating box 90 through the two connecting rods 1010. 1 moves to one side to avoid obstacles in movement, and after stopping, the rotating ring 1014 no longer rotates, so that the small generator 1017 stops supplying power to the electromagnet 1012, and then the movable column 1009 moves back, so that the conductive plate 1004 contacts the end conductive strip 9076, so that the heating strip 903 is connected to the circuit, wherein when the movable frame 805 moves toward the side of the second air inlet baffle 6, the arc surface 1005 on the conductive plate 1004 can generate pressure on the end of the first side plate 9075, so that the power connection block 9071 moves toward the vertical plate 902, which is convenient for the starting of the movable frame 805.
