Abstract

The invention discloses a direction self adjusting ventilating cowl which comprises an air outlet pipe, an air inlet pipe, a bearing base and a first bearing and a second bearing which are arranged on the upper side of the bearing base. The second bearing is arranged on the inner side of the first bearing and coaxial with the first bearing. A vertical air outlet section of the air outlet pipe is connected with the first bearing, and a vertical air inlet section of the air inlet pipe is located in the air outlet pipe and connected with the second bearing. A first air vent and a second air vent connected with upper side and the lower side of the bearing base are arranged on the bearing base, the air outlet pipe is connected with the lower side of the bearing base through the first air vent, and the air inlet pipe is connected with the lower side of the bearing base through an inner hole and the second air vent. The direction self adjusting ventilating cowl drives indoor air inlet and air outlet through natural wind and hot pressure supplied by solar heat collection and heat accumulation materials so as to achieve bidirectional ventilating. Simultaneously, total heat exchangers are arranged in buildings according to difference in use purposes of the buildings, energy is saved by using temperature difference of air inlet and air outlet to perform heat exchange, and the environment is protected.

Description

technical field [0001] The invention relates to an automatic ventilation energy-saving device applied to buildings, in particular to a self-adjusting direction ventilation cap. Background technique [0002] The current building ventilation devices are mainly driven by the power supply. When the power supply is used, it will consume a lot of power and cause a certain degree of damage to the environment. In recent years, ventilators without power have also been developed, but it cannot be realized simultaneously The purpose of air intake and exhaust has limited effect on building energy saving. Through searching, it is found that the Chinese utility model patent: Pneumatic energy storage heat preservation and dehumidification two-way ventilation cap, patent number: ZL200920071880.6, this patent relates to a ventilation device, which includes an exhaust pipe, an air inlet pipe, a heat exchange box, and a bearing , the components are connected in turn as a whole, the device can...
