Problems solved by technology
[0002] Electromechanical equipment almost runs through our lives. Nowadays, most household exhaust fans only have the effect of exhausting, and their functions are relatively single, and they are always at the same speed. Certain energy consumption causes unnecessary consumption. On the other hand, when the temperature is low in winter, the indoor temperature is greatly reduced because the exhaust fan is always connected to the outside world, which has a certain impact on human senses.

The invention relates to the related field of electromechanical equipment, and discloses a heating exhaust fan capable of automatically adjusting the exhaust effect according to the temperature. The heating exhaust fan comprises a main body box, a fan cavity penetrating front and back is formed in the main body box, a reversing cavity is formed in the upper side of the fan cavity, a reversing shaft cavity is formed in the rear side of the reversing cavity in a communicated manner, and a motor gear cavity extending upwards is formed in the rear side of the reversing shaft cavity in a communicated manner. According to the heating exhaust fan, the external temperature is judged through heat expansion and cold contraction of liquid in a temperature telescopic liquid cavity, when the temperature is normal, the exhaust fan can be directly turned on to perform ventilation operation on the indoor place, meanwhile, the rotating angle of fan blades can be increased according to temperature rise,the exhaust effect is gradually enhanced, and the power of the fan is reasonably utilized; when the temperature is low, the fan blades rotate to be closed, the indoor space is isolated from the outdoor space, and therefore the indoor heat loss is avoided; and when the temperature is too low, a heating net can be started to heat while the fan blades are reversed, hot air is blown into the indoor space, and the indoor temperature is increased.
Description
technical field [0001] The invention relates to the related field of electromechanical equipment, in particular to a heating exhaust fan which can automatically adjust the exhaust effect according to the temperature. Background technique [0002] Electromechanical equipment almost runs through our lives. Nowadays, most household exhaust fans only have the effect of exhausting, and their functions are relatively single, and they are always at the same speed. A certain amount of energy consumption causes unnecessary consumption. On the other hand, when the temperature is low in winter, the indoor temperature is greatly reduced because the exhaust fan is always connected to the outside world, which has a certain impact on human senses. Contents of the invention [0003] The purpose of the present invention is to provide a heating exhaust fan that can automatically adjust the exhaust effect according to the temperature, which can overcome the above-mentioned defects of the pri...
