Portable intelligent household exhaust machine

Abstract

The invention provides a portable intelligent household exhaust machine and belongs to the field of air purification fresh air. The portable intelligent household exhaust machine is composed of an exhaust machine tool frame assembly, an exhaust assembly and an air sensing power source switch assembly; the exhaust machine tool frame assembly is internally provided with a stretching and contracting adjustment plate, the length of the whole machine can be adjusted by the stretching and contracting adjustment plate, and the stretching and contracting adjustment plate is suitable for installing leftward-rightward-movement type windows of different sizes; the two ends of the stretching and contracting adjustment plate are provided with bayonets, and the whole machine can be clamped to rails at the upper end and the lower end of a mobile window frame through the bayonets; the air sensing power source switch assembly is composed of an air quality sensor module, a corresponding electronic control panel and power lines and controls the exhaust assembly; when the concentration of harmful gases, such as formaldehyde, carbon dioxide and carbon monoxide is excessively high or oxygen is insufficient in a room, the exhaust machine is started automatically to exhaust towards the outside; and meanwhile, indoor air flows into the room through various ways to supplement fresh air, such as oxygen so that the indoor air can be always highly-qualified and safe. The installation method of the portable intelligent household exhaust machine comprises the steps that a window is moved away, the whole machine is vertically clamped into the window frame, the window is closed, window gaps are sealed, and the portable intelligent household exhaust machine is used after a power source is plugged in.

Description

Technical field: [0001] The invention relates to air purification, fresh air system and automatic control technology, in particular to the technical field of air sensing electronic switches. Background technique [0002] Exhaust machine is a device used to exhaust air to exchange air. Common ones include range hood, toilet exhaust fan and fresh air system. [0003] With the decline in outdoor air quality and the widespread use of indoor heating and cooling equipment, closing doors and windows has become the norm in family life. After the doors and windows are closed, harmful gases such as formaldehyde, benzene, styrene, radon, carbon dioxide, and carbon monoxide generated in the room will gradually accumulate and increase, and the oxygen will gradually decrease, which will endanger human health in serious cases. Existing commonly used range hoods, toilet exhaust fans and other ventilation equipment are only used in specific areas at specific times, and cannot effectively discharge...

AI Technical Summary

Problems solved by technology

However, the existing commonly used range hoods, bathroom exhaust fans and other ventilation equipment are only used in specific areas at specific times, and cannot effectively and timely discharge harmful gases in important places where people live, such as bedrooms, study rooms, and living rooms; they have been widely used in recent years. Although the fresh air system can solve such problems, it generally needs to be installed before moving in, and the amount of work is relatively large. However, if a large number of users who have not installed the fresh air system reinstall it, they usually have to break the wall and punch holes. Damaged, time-consuming and labor-intensive and affect the appearance
