Embodiment Construction

[0013] A switch control system for a fresh air machine, which includes: a fresh air machine, the power switch of which is connected to a control device; a first air detector is arranged outside the application environment of the fresh air machine, and the application environment of the fresh air machine A second air detector is provided in the environment, and the first air detector and the second air detector are respectively connected to the control device; when the first environmental value detected by the first air detector is consistent with the When the ratio of the second environmental value detected by the second air detector is not greater than the set value, the control device sends a stop signal to the power switch.

[0014] Specifically, the set value is 1.2.

[0015] Specifically, the first air detector and the second air detector are one of a CO2 sensor, a PM2.5 sensor, a PM10 sensor and a TVOC sensor.

[0016] The on / off control system of the fresh air blower o...

Abstract

The invention discloses an on-off control system of a fresh air fan. The on-off control system comprises the fresh air fan. A power switch of the fresh air fan is connected with a control device. A first air detector is arranged on the outer side of an application environment of the fresh fan. A second air detector is arranged in the application environment of the fresh air fan. The first air detector and the second air detector are connected with the control device. When the ratio of the first environmental value detected by the first air detector to the second environmental value detected bythe second air detector is not greater than 1.2, the control device sends a stop signal to the power switch. According to the on-off control system of the fresh air fan, the power switch of the freshair fan is controlled by a voice control switch and a human body infrared sensor, so that the intelligent turning-off of the fresh air fan is realized.

Description

technical field [0001] The invention relates to the technical field of fresh air blower control, in particular to a fresh air blower switch control system. Background technique [0002] The fresh air fan is an effective air purification equipment. On the one hand, it discharges the indoor dirty air to the outside, and on the other hand, it takes the outdoor fresh air into the room after sterilization, disinfection, filtration and other measures, so that the room can be cleaned every day Always fresh and clean air. The fresh air fan uses fresh air convection technology to achieve convection of indoor air through independent air supply and induction, thereby maximizing indoor air replacement, and the built-in filter element ensures that the air entering the room is clean and healthy. [0003] However, when the filter screen in the fresh air machine has reached its service life, if you continue to use it, the effect of filtering the air will not be achieved, and the pollutants...
