Air inlet and outlet device of house ventilator

Abstract

The invention discloses an air inlet and outlet device of a house ventilator, which comprises an air inlet device and an air outlet device. The air inlet device and the air outlet device are structurally symmetric and respectively comprise a shell, a filter, fan blades, a ventilation opening, a ventilation pipe and a lower cover, the shell is of a sector structure, an adjustment opening is arranged at the upper end of the shell, the filter is mounted inside the shell, the fan blades are mounted inside the shell close to the filter, a holder and an external hole are arranged on the lower cover, the external hole corresponds to an external opening of the ventilation pipe, and the lower cover is mounted on one sector side of the shell. The air inlet and outlet device has the advantages that air inlet and outlet amount can be increased for a house, short-term air outlet directions are optionally controlled, and filterability is enhanced.

Description

technical field [0001] The invention relates to an air inlet and outlet device, in particular to an air inlet and outlet device for a house ventilator, which is mainly installed at the air inlet and outlet of the house ventilator. Background technique [0002] At present, there is an increasing demand for housing ventilators in the market, and housing ventilators are more widely used in cities. Since indoors and outdoors are in a closed state, the indoor air is not stable in terms of oxygen content or freshness. It is greatly reduced, so the house ventilator has a broader market prospect, but at this stage, the house ventilator is directly in and out at the air inlet and outlet ends, which leads to insufficient air in and out, and at the same time, due to a large amount of dust outside When the air is inhaled by the ventilator, the air cannot be completely cleaned, so it may be directly inhaled into the room, which will have an adverse effect on human health.
