Description

Intake and exhaust mechanism of ventilation equipment

This creation is related to the technical field of a ventilation device, especially the intake and exhaust mechanism of a ventilation device.

Generally speaking, bathrooms are often filled with a lot of moisture, and the way people handle moisture is mostly controlled by ventilation. Especially in Taiwan and the humid subtropical climate, the bathrooms often become hotbeds for bacteria and molds. If it happens to be a bathroom space without windows for lighting, mold will often grow on the walls and towels in the bathroom. Generally, in order to solve the above-mentioned moisture problem, ventilation equipment is often installed in the bathroom. The ventilation equipment is a ventilation pipe. Connected to the top to extract moisture and air from the bathroom and exhaust it outside the bathroom.

However, when the ventilating equipment does not operate, the dirty air from the outside will be injected into the room through the vent, causing the indoor air to be polluted and causing considerable trouble to the residents. In modern buildings, common ventilation ducts are usually used as the ventilation paths for residents' toilets. Therefore, all residents use their own exhaust fans to discharge the odor in the toilets into the ventilation ducts. Only when the ventilation equipment does not operate, the odor in the ventilation duct will be poured into the toilet from the vent, causing the air in the toilet to be polluted.

However, the exhaust plate of the previous ventilation equipment uses a spring to return, but the torsion generated by the spring will cause the drive motor to be easily damaged, and the spring will cause elastic fatigue when the spring is used frequently, making the opening and closing of the exhaust plate incomplete. It can be seen that there is still a need to improve the previous control components.
