Backwash self-cleaning ventilation device

Abstract

A backwash self-cleaning ventilation device comprises a fresh air host arranged in a room and a filter box mounted outside the room. The filter box and the fresh air host are connected into a whole body through a connecting module, the indoor fresh air host comprises a screen shell body and a temperature probe, fan blades and a fan blade motor are mounted in the screen shell body, and the fan blade motor and the temperature probe are connected with a control system; the connecting module is a flange connecting part; the outdoor filter box comprises a protection screen box, a filter screen support is mounted in the protection screen box, a filter screen is mounted on the filter screen support, a cleaning brush and a brush motor are mounted in the protection screen box, the cleaning brush is in contact with the filter screen, and the brush motor is connected with the control system; and according to the scheme, use and mounting are easy and convenient, the device can be subject to self cleaning while the site required to be ventilated is provided with a filtering ventilation device, the cost spent by the situation that in the later period, maintaining of the ventilation device needs a large amount of manual work is removed, and the device is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to an energy-saving, self-cleaning and maintenance-free backwashing self-cleaning ventilation device, which belongs to the field of ventilation equipment. Background technique [0002] At present, conventional purification ventilation devices are all detachable filters, and later maintenance needs to be manually dismantled or replaced regularly. However, due to the particularity of some places (such as communication base stations in remote areas, etc.), it takes a lot of manpower and material resources to replace and clean the filters. Larger, cumbersome, and time-consuming. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art, and provide a backwashing self-cleaning ventilation device that can clean the machine itself without manual maintenance, is energy-saving and environmentally friendly, and has the function of filtering and ventilation. [0004] The techni...
