Wall-through purification ventilation pipe with structure for regulating ventilation flow

Abstract

The invention discloses a through-wall purifying ventilating pipe with a ventilating flow adjusting structure. The through-wall purifying ventilating pipe comprises a ventilating pipe and an air volume adjusting device comprising a valve and a transmission unit. The transmission unit comprises a screw rod, a nut and a driving motor. A circle of retaining flanges is arranged on the inner side of the ventilating pipe. Four limiting sensors, a PLC, a PM2.5 sensor and a CO2 sensor are further arranged. The through-wall purifying ventilating pipe with the ventilating flow adjusting structure is small in mounting space, easy to operate and reliable in structure; and a filter net of a novel structure is arranged in the ventilation pipe, the purpose of prolonging the contact time of gas and the filter net is achieved by prolonging the filter path of the gas, and the purifying efficiency of the filter net is high.

Description

technical field [0001] The invention belongs to the field of gas purification and ventilation equipment accessories, in particular to a wall-penetrating purification ventilation pipe with a structure for adjusting ventilation flow. Background technique [0002] Air purifiers refer to products that can absorb, decompose or transform various pollutants in the air and effectively improve the cleanliness of indoor air. It is used in home, medical and industrial fields. In the field of home, single-unit household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and it can also solve the problem of volatile organic compounds in indoors, underground spaces, and cars caused by decoration or other reasons. [0003] The air purifier filters the fresh outdoor air into the room through the ventilation duct, and at the same time discharges the dirty air from the room to the out...

Problems solved by technology

However, the single valve plate used in this traditional structure must be made relatively thick in order to withstand the wind pressure. In addition, the rotation of the valve plate needs to occupy a large space. It cannot play its role in places where the installation space is narrow and the equipment is dense.

[0004] The patent application number is the Chinese patent of CN200510130459.4, and the patent name is: a simple natural fresh air indoor device, which discloses a ventilation pipe, a louver and an air filter, the louver is installed on the outer end of the ventilation pipe, and the air filter Installed on the cross-section of the ventilation pipe, although it solves the problem of indoor ventilation, the filtering effect is poor, and it does not have the function of adjusting the air volume, so it does not solve the above problems
