[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is a customary abbreviation for gas compression and gas delivery machinery. The fans usually mentioned include ventilators, blowers, and wind turbines. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induced draft of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains, inflation and propulsion of wind tunnel wind sources and hovercraft, etc. Fans belong to the energy-saving and environmental protection industry. Fan products cover various large industrial fans, external rotor fans, centrifugal fans, axial flow fans, air conditioning fans, diagonal flow fans, boiler induced draft fans, fire smoke exhaust fans, inverter welding machines, smart chargers, motors and other fans and electromechanical products. Traditional fan equipment has problems of high energy consumption and low efficiency; the noise and pollution generated by traditional fans burden the environment; the existing fans are difficult to maintain, affecting the efficiency and life.

[0003] A window-type fresh air fan is a ventilator installed on a window. It relies on the power device that comes with the product to achieve ventilation. Its function is to adjust the temperature, humidity, cleanliness, air flow rate and other parameters in the room (or closed space, area) by adjusting the outdoor fresh air speed to meet the comfort requirements of the human body.

When the guide fan of the fan assembly rotates, it can directly guide the airflow, so that the airflow is transported from the outdoors to the indoors in a directional manner, thereby improving the effectiveness of introducing fresh air and improving the working efficiency of the fresh air blower.

[0037] (2) The liftable and environmentally friendly window-type fresh air fan of the present invention captures the external airflow through the outer opening of the ball bin and transports it to the inside of the first cover shell, and uses the natural wind flow to drive the second air capture fan and the first air capture fan to rotate, and uses the fourth pulley and the third belt to drive the guide fan of the fan assembly to rotate and transport air, thereby improving the energy saving of the fresh air fan when in use.

[0038] (3) The liftable and environmentally friendly window-type fresh air blower in the present invention is fixedly connected to the ground flag plate through the inner side of the wind rod, and can rotate the ball bin according to the external wind direction, so that the outer opening of the ball bin is facing the wind source, so that the external mechanism can directly inject the external wind flow, thereby improving the wind capture effect of the fresh air blower.

[0039] (4) The environment-friendly window-type fresh air blower that can be raised or lowered in the present invention can have the water accumulated at the bottom of the ball bin humidify the air flow injected through the wind-catching component.

[0040] (5) The environment-friendly window-type fresh air blower that can be raised and lowered in the present invention can, by setting a water pipe on the wind-catching net, allow the accumulated water to flow into the water pipe through the rotation of the wind-catching net and flow out from the other end hole of the water pipe to clean the surface of the wind-catching net, so that the wind-catching net and the second wind-catching fan can perform self-cleaning, thereby improving the cleaning ability of the fresh air blower.

[0041] (6) In the present invention, the environment-friendly window-type fresh air blower that can be raised or lowered, rainwater will continuously accumulate in the ball bin during rainfall, and when the height of the accumulated water exceeds the outer opening of the ball bin, it will overflow. At this time, the dust washed away will flow out synchronously with the water flow, thereby utilizing the natural environment to replace the washing water source, thereby improving the green environmental protection of the fresh air blower.

[0042] (7) The environment-friendly window-type fresh air blower that can be raised and lowered in the present invention can automatically tighten the second belt after the electric mechanism is activated through the design of the gears and gear grooves, thereby improving the automation performance of the fresh air blower.

[0043] (8) The environment-friendly window-type fresh air blower of the present invention can be raised and lowered. By setting a scraper brush, when the guide fan rotates to guide the air, the scraper brush can wipe off and gather the dust on the surface of the dust screen, thereby ensuring the smooth flow of the dust screen during operation and further improving the cleaning ability of the fresh air blower.

[0044] (9) The environment-friendly window-type fresh air blower that can be raised and lowered in the present invention can make the second roller rotate in one direction through the blocking of the spring piece and the block, and the wind flow can drive the fan blades to rotate, and then the conveyor belt is moved from the first ash outlet to the second ash outlet through the second roller, and the scraped dust is sent out simultaneously, and the dust is automatically cleaned by using external resources, thereby improving the energy saving and environmental protection of the fresh air blower.

[0099] When the external wind is strong enough, the electric mechanism 3 is not activated and the second belt 306 of the electric mechanism 3 is kept in a relaxed state at ordinary times. The door panel 108 is raised by the starter 107, and the telescopic column 510 is extended to send the ball bin 501 out of the outlet slot 106. The external airflow is captured and transported to the inside of the first cover shell 101 through the outer opening of the ball bin 501, and the natural wind flow is used to drive the second air capture fan 507 and the first air capture fan 407 to rotate, and the fourth pulley 405 and the third belt 406 are used to drive the guide fan 205 of the fan assembly to rotate and transport air, thereby improving the energy saving of the fresh air fan when in use.

[0100] By fixing the ground flag plate 509 on the inner side of the wind rod 508, the ball bin 501 can be rotated according to the external wind direction, so that the outer opening of the ball bin 501 is facing the wind source, so that the external mechanism 5 can directly inject external wind flow, thereby improving the wind catching effect of the fresh air fan.

[0101] During rainfall outside, rainwater will enter the ball bin 501 through the outer opening of the ball bin 501 and gather on the lower side of the inner part of the ball bin 501. The outer opening of the ball bin 501 is larger than the radius of the bellows 502, which effectively avoids rainwater backflow. The accumulated water at the bottom of the ball bin 501 can humidify the airflow injected through the wind capture component. The heater 102 is used to manage the air temperature, which can prevent the air introduced by the fresh air fan from being too dry and effectively adjust the humidity of the indoor air.

[0102] After water accumulates inside the ball bin 501, the lower sides of the second fan 507 and the wind catching net 503 will contact the accumulated water during rotation. Therefore, the second fan 507 can drive the accumulated water to clean itself during rotation. In addition, through the setting of the water pipe 505 on the wind catching net 503, the accumulated water can be poured into the water pipe 505 through the rotation of the wind catching net 503 and flow out from the other end hole of the water pipe 505 to clean the surface of the wind catching net 503, so that the wind catching net 503 and the second fan 507 can perform self-cleaning, thereby improving the cleaning ability of the fresh air fan.

[0103] During rainfall outside, rainwater will continue to accumulate in the ball bin 501, and when the height of the accumulated water exceeds the outer opening of the ball bin 501, it will overflow. At this time, the cleaned dust will flow out synchronously with the water flow, thereby utilizing the natural environment to replace the cleaning water source and improving the green environmental protection of the fresh air fan.

[0104] When the external wind source is insufficient, the electric mechanism 3 is activated, and the motor 303 drives the gear 307 to rotate. Through the meshing of the gear 307 and the tooth 309, the motor 303 slides as a whole along the second bracket 301 to the arc groove 310 of the matching gear 307 opened on the gear groove 308, and then automatically straightens the loose second belt 306, thereby actively driving the fan assembly to operate. Through the design of the gear 307 and the gear groove 308, the second belt 306 can be automatically tightened after the electric mechanism 3 is activated, thereby improving the automation performance of the new air fan.

[0105] Through the built-in guide fan 205 of the fan assembly, a fixed wind direction is formed, and the airflow enters the other side from the ash screen 203. Most of the external air dust is isolated on the outside of the ash screen 203. Through the setting of the scraper brush 206, when the guide fan 205 rotates to guide the air, the scraper brush 206 can wipe off and gather the dust on the surface of the ash screen 203, thereby ensuring the smooth flow of the ash screen 203 during operation, and further improving the cleaning ability of the fresh air fan.

[0106] The dust isolated on the outside of the ash screen 203 is gathered by the scraper 206 and falls into the first ash opening 602 on the bottom plate bin 601 under the action of gravity. The outer side of the bottom plate mechanism 6 extends out of the outer plate 105. When it is windy outside, the second roller 606 is blocked by the spring piece 610 and the block 609 to make the second roller 606 rotate in one direction. The wind flow can drive the fan blade 612 to rotate, and then the conveyor belt 604 is moved from the first ash opening 602 to the second ash opening 603 through the second roller 606, and the scraped dust is sent out simultaneously, and the automatic cleaning is performed using external resources, thereby improving the energy saving and environmental protection of the fresh air fan.

[0107] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
