Problems solved by technology

[0003] Most of the currently used air purification devices are single-motor-single-fan integrated air filter devices, which are divided into the following three types: indoor self-priming purification, indoor and outdoor one-way exchange, and two-way dual-system air exchange filter equipment. The air purification and filtration device used has various problems such as low energy utilization rate, low purification efficiency, and the system can only work in one direction.
[0004] The two-way dual-system air exchange filter device has obvious disadvantages such as serious waste of energy, low system integration, and large space occupation, while the one-way filter purification device has the problem of changing the air pressure balance in a relatively closed indoor environment, which lasts for a long time and gradually increases. The positive pressure and negative pressure living environment will cause more or less adverse effects on the physiology and psychology of the human body
For example, when a person is in a positive pressure environment for a long time, it is easy to form an air embolism and cause a variety of diseases, aggravating bronchitis, children's asthma and other adverse diseases and other disease reactions; What's more, when cerebral hypoxia occurs, various symptoms such as dizziness, nausea, vomiting and asthenia will appear, which pose a certain degree of threat to human life, health and safety

Embodiment 1

[0034] Such as figure 1 As shown, this embodiment provides an air filter system capable of maintaining constant net and constant pressure, including: an exhaust module and an exhaust module;

[0035] The exhaust module includes an external air outlet duct 1 and an internal air suction duct 5; the exhaust module includes an external air suction duct 2 and an indoor air outlet duct 4;

[0036] In this embodiment, the port of the external air duct 1 is connected to the outside world, and is matched with the internal air suction duct 5 on the basis of the single frequency conversion motor-double fan device 3,

[0037] The internal suction duct 5 is a plurality of circular air inlets arranged vertically, and the apertures arranged in parallel are about 1 / 5 of the size of the air inlets, so that when the fan performs internal suction work without considering the air volume, the working range The columns are evenly and vertically arranged; the exhaust module is composed of the exter...

Abstract

The invention discloses an air filtering device system capable of keeping constant cleanliness and constant pressure. The air filtering device system comprises an air exhaust module, an air draft module and a single variable frequency motor-double fan device, the single variable frequency motor-double fan device comprises a first fan, a second fan, an air filtering module and a variable frequency motor; the first fan is connected with the air exhaust module through the air filtering module, and the second fan is connected with the air draft module; the first draught fan and the second draught fan are connected through a connecting pipe, a gear is arranged on the connecting pipe, and the axle center of the first draught fan and the axle center of the second draught fan are tangent through the gear, so that under driving of the variable frequency motor, the first draught fan and the second draught fan synchronously and reversely run at the constant speed, and inlet air and outlet air of the air draft module and the air exhaust module run equivalently. The air draft module and the air exhaust module achieve real-time equivalent air inlet and outlet, the axle center of the first fan and the axle center of the second fan are tangent through gears, the effect that the gears reversely move is achieved, constant-speed reverse of the fans is achieved, and the indoor and outdoor constant-pressure and constant-cleanliness effect is kept.

Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to an air filtration device system capable of maintaining constant net and constant pressure. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Most of the currently used air purification devices are single-motor-single-fan integrated air filter devices, which are divided into the following three types: indoor self-priming purification, indoor and outdoor one-way exchange, and two-way dual-system air exchange filter equipment. The air purification and filtering device used has many problems such as low energy utilization rate, low purification efficiency, and the system can only work in one direction. [0004] The two-way dual-system air exchange filter device has obvious disadvantages such as serious waste of energy, low system integration,...
