Description

Technical Field

[0001] The invention relates to the technical field of positive air compressors, and in particular to an energy-saving positive pressure fan for air conditioning. Background Art

[0002] The positive pressure fan drives the fan blades to rotate through the motor, generating a strong airflow, which sends fresh outdoor air into the room after filtering and purification. With the continuous input of fresh air, the indoor air pressure gradually increases, forming a positive pressure state. This positive pressure difference causes the indoor dirty air to be naturally squeezed to low-pressure areas such as the gaps between doors and windows and discharged, thereby achieving continuous circulation and replacement of indoor air.

[0003] Positive pressure fans are suitable for air conditioning in pig farms and factories, but they cannot be used normally in places that need to be kept dry consistently in humid weather, rainy days and other weather with high moisture content, because in such weather, positive pressure fans will input external humid air and moisture along with the wind, causing the ground and air to become wet, thus affecting the site environment.

[0032] The driving mechanism 4 includes a motor 41 fixed on the top of the box body 11 , and a gear 42 is fixed to the output end of the motor 41 . One side of the gear 42 is meshed with the one-way gear 1 22 , and the other side of the gear 42 is meshed with the one-way gear 2 214 .

[0033] A controller is fixed on one side of the box body 11 , and the controller is electrically connected to the power supply, the solar charging panel, the motor 41 , the heating box 33 , the solenoid valve and the blowing fan 13 .

[0034] Working principle: The controller starts the blowing fan 13, and the blowing fan 13 runs to eject air from the air outlet 12. When the humidity detector built into the controller detects that the air humidity is too high, the motor 41 is started to drive the gear 42 to rotate forward. The forward rotation of the gear 42 satisfies the direction of the one-way gear 1 22 driving the reciprocating screw 1 21 to rotate. The reciprocating screw 1 21 rotates through the pulley 1 218, the pulley 219 and the belt 220 to drive the reciprocating screw 3 216 to rotate, so that the moving frame 23, the moving block 1 217 and the moving block 222 move downward. The moving frame 23, the moving block 1 217 and the moving block 222 move downward and drive the structure connected thereto to move downward, so that the extrusion plate 29 and the mesh plate 225 move to the two sides of one of the filter cottons 227. During the movement, the bevel gear 1 27 pushes the bevel gear 213 to drive the slider 212 to move synchronously downward along the slide 211. When moving upward, the reciprocating screw 25 drives the L-shaped plate 215 to support the bevel gear 213 to drive the slider 212 to move inside the slide 211. The controller controls the motor 41 to drive the gear 42 to reverse, and the reverse rotation of the gear 42 satisfies the direction of the rotation of the one-way gear 214 to drive the rotating shaft 210 to rotate. The rotation of the rotating shaft 210 drives the slider 212 and the bevel gear 213 to rotate, and the bevel gear 213 drives the bevel gear 1 27 to rotate. The bevel gear 1 27 drives the reciprocating screw 25 to rotate so that the threaded cylinder 26 pushes the extrusion plate 29 to move toward the filter cotton 227 to compress the filter cotton 227. One side of the filter cotton 227 is limited by the mesh plate 225. During the compression process, the water filtered by the filter cotton 227 enters the water flow channel 223 from the mesh plate 225. The air flows out of the box 11 through the flexible water outlet pipe 224, and the solenoid valve and the heating box 33 are started at the same time. Part of the air from the fan 13 enters the air inlet cover 32, and then enters the heating box 33 along the air guide pipe 31. The heating box 33 heats the air. The heated air enters the gas channel 35 through the flexible air outlet pipe 34, and then contacts the compressed filter cotton 227 through the air outlet slot 36 and a plurality of water blocking plates 37. The wind blows the water in the filter cotton 227 toward the mesh plate 225, reducing the residual water inside. At the same time, the heat dries the filter cotton 227 to keep it dry. When the extrusion plate 29 moves, the telescopic rod 28 is stretched. The telescopic rod 28 plays a guiding and stabilizing role in the process of the extrusion plate 29 moving. After the threaded barrel 26 moves to the thread tail of the reciprocating screw 25, it pulls the extrusion plate 29 back and forth, and the filter cotton 227 is reset accordingly. The motor 41 drives the gear 42 to rotate forward, so that the reciprocating screw 1 21 and the reciprocating screw 3 216 continue to rotate, so that the extrusion plate 29 and the mesh plate 225 and other structures move down to the position of the next filter cotton 227 for drying. The moisture filtering and processing mechanism 2 and the filtering and drying mechanism 3 filter and process the moist air, reduce the humidity of the air sprayed by the air supply mechanism 1, keep the air dry, and solve the problem that the positive pressure blower cannot be used in places that need to be dried in humid weather or rainy days.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
