Abstract
The invention discloses a startup and shutdown control system of a fresh air machine, which comprises the fresh air machine, wherein a power switch of the fresh air machine is connected with a control device; a first air detector is arranged outside the application environment of the fresh air machine, a second air detector is arranged inside the application environment of the fresh air machine, and the first air detector and the second air detector are respectively connected with the control device; and when the ratio of the first environment value detected by the first air detector to the second environment value detected by the second air detector is not more than 1.2, the control device sends a stop signal to the power switch. The on-off control system of the fresh air machine controls the power switch of the fresh air machine through the voice control switch and the human body infrared sensor, so that the fresh air machine is intelligently turned off.
Description
Technical Field
The invention relates to the technical field of fresh air machine control, in particular to a startup and shutdown control system of a fresh air machine.
Background
The fresh air machine is an effective air purification device, on one hand, dirty air in a room is discharged out of the room, on the other hand, fresh air outside the room is input into the room after measures such as sterilization, disinfection, filtration and the like, and the air in the room is fresh and clean air at all times. The new fan utilizes new trend convection technique, through independently supplying air and induced air, makes the room air realize the convection current to the furthest carries out the room air replacement, and guarantees through built-in filter core that the air that gets into indoor is clean healthy.
However, when the filter screen in the fresh air fan reaches the service life, the effect of filtering air cannot be achieved if the filter screen is continuously used, and pollutants accumulated in the filter screen cause secondary pollution to users; if the existing new fan needs to be manually turned on or turned off, a user easily forgets to replace the filter screen regularly.
Disclosure of Invention
The invention aims to provide a switch-on and switch-off control system of a fresh air fan, which effectively solves the problems in the prior art.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a startup and shutdown control system of a new fan comprises: the power switch of the fresh air machine is connected with a control device; a first air detector is arranged outside the application environment of the fresh air machine, a second air detector is arranged inside the application environment of the fresh air machine, and the first air detector and the second air detector are respectively connected with the control device; and when the ratio of a first environment value detected by the first air detector to a second environment value detected by the second air detector is not more than a set value, the control device sends a stop signal to the power switch.
As a specific example, the set value is 1.2.
As a specific example, 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.
Compared with the prior art, the invention has the following technical effects:
according to the startup and shutdown control system of the fresh air machine, the first environment value and the second environment value detected by the first air detector and the second air detector which are respectively positioned inside and outside the application environment are compared, when the ratio of the first environment value to the second environment value is not more than 1.2, the fact that the filter screen has reached the limit service life is proved, the filter screen cannot play a role in filtering after being continuously used, and at the moment, the control device automatically controls the fresh air machine to stop, so that the intelligent shutdown effect is achieved.
For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a switch control system of a fresh air machine of the invention.
Detailed Description
A startup and shutdown control system of a new fan comprises: the power switch of the fresh air machine is connected with a control device; a first air detector is arranged outside the application environment of the fresh air machine, a second air detector is arranged inside the application environment of the fresh air machine, and the first air detector and the second air detector are respectively connected with the control device; and when the ratio of a first environment value detected by the first air detector to a second environment value detected by the second air detector is not more than a set value, the control device sends a stop signal to the power switch.
Specifically, the set value is 1.2.
Specifically, the first and second air detectors are one of a CO2 sensor, a PM2.5 sensor, a PM10 sensor, and a TVOC sensor.
According to the startup and shutdown control system of the fresh air machine, the first environment value and the second environment value detected by the first air detector and the second air detector which are respectively positioned inside and outside the application environment are compared, when the ratio of the first environment value to the second environment value is not more than 1.2, the fact that the filter screen has reached the limit service life is proved, the filter screen cannot play a role in filtering after being continuously used, and at the moment, the control device automatically controls the fresh air machine to stop, so that the intelligent shutdown effect is achieved.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
