Fresh air ventilation device and full-automatic and intelligent ventilation equipment

Abstract

The invention provides a fresh air ventilation device and relates to the technical field of air purification. The fresh air ventilation device comprises a casing, fresh air ports, exhaust ports, an external connection port, a first fan and a second fan; the fresh air ports, the exhaust ports and the external connection port are formed in the side walls of the casing; the first fan and the second fan are arranged in the casing; the fresh air ports communicate with the first fan through the external connection port; and the exhaust ports communicate with the external connection port through the second fan. The fresh air ventilation device has the independent exhaust mode, so that the problem of air flow short-circuiting of a bidirectional flow pipeline-free fresh air ventilator is avoided; besides, the first fan and the second fan which are independent of each other are adopted, the fresh air pressure and the exhaust pressure are adjusted according to the actual requirements, and the ventilation efficiency of the device is improved; besides, with the single external connection port, the perforating number in a wall is reduced, the device is simple and convenient to mount, and meanwhile, the potential safety hazards to the wall due to perforation are reduced. On the basis, the invention further provides full-automatic and intelligent ventilation equipment.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a fresh air ventilation device and fully automatic intelligent ventilation equipment. Background technique [0002] With the development of the economy, the ambient air quality continues to decline, and the haze weather occurs frequently, and people's demand for fresh air ventilators is becoming more and more urgent. The traditional ceiling-type fresh air ventilator needs to be designed with piping. The suspended ceiling not only reduces the height of the house and increases the difficulty of construction, but also the pipes in the suspended ceiling are likely to cause secondary pollution. Therefore, the "ductless fresh air ventilator" that does not require piping Came into being. [0003] There are two types of "ductless fresh air ventilators" on the market: one-way flow ductless fresh air ventilators and two-way flow ductless fresh air ventilators. Among them, the on...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fresh air ventilator to solve the problems that the fresh air ventilator in the prior art cannot quickly discharge indoor polluted air, the air inlet pipe and the exhaust pipe have partial short circuits, etc.
