Negative-pressure fresh air inlet device

Abstract

The invention relates to a negative-pressure fresh air inlet device. The negative-pressure fresh air inlet device comprises an exhaust mechanism and an air inlet mechanism. The air inlet mechanism comprises a main frame, a fan, an air filter element and a heating body. The heating body is arranged below the air filter element and above the fan. The fan is connected with a wind driven generator. The wind driven generator is electrically connected with the heating body. The air filter element is detachably connected into the main frame. The fan is arranged at the bottom of the main frame. The fan is pushed through inlet air flow, the fan drives the wind driven generator, generated electric power is transmitted to the heating body, the air filter element above the fan forms certain wind resistance for the inlet air flow, and then a cavity around the heating body heats the inlet air flow to achieve the dehumidification effect. The heating body conducts auxiliary heat on outdoor cold air inwinter, and the negative-pressure fresh air inlet device is more environmental-friendly and energy-saving. Meanwhile, the drying and bacteriostatic effects are achieved on the detachable air filter element above the heating body, movable shutters are in a closed state when the exhaust mechanism does not work, indoor heat is prevented from being lost, fragrance can be placed on a storage rack, andthe whole room is fragrant.

Description

technical field [0001] The invention relates to the technical field of fresh air ventilation, in particular to a negative pressure fresh air intake device. Background technique [0002] At present, the conventional two-way fresh air requires the laying of pipes, and in order to meet the current decoration style, the pipes have largely destroyed the load-bearing beams, and the project is huge, the cost is high, and it needs to be hidden by the ceiling. It is also very troublesome to repair and replace the filter element in the later stage. The price of the heat conduction type total heat exchange filter element for pressure fresh air is relatively high, and the other part of negative pressure fresh air cannot solve the problem of cold air entering the room in winter and the problem of outdoor humid weather, and the outer wall needs to be installed with an air inlet, which is difficult to install, and the window glass is installed with air intake The mouth affects the appearan...
