Referring to fig. 1 to fig. 3, in the present embodiment, the control module includes a housing 10, a power input port 20, a power output port 30, a processing unit 40, a sensor unit 50, a first switch unit 60, a second switch unit 70, and a power management system 80. The processing unit 40, the sensor unit 50, the first switch unit 60, the second switch unit 70, and the power management system 80 are integrated on a circuit board 200 within the housing 10. The housing 10 serves to achieve electrical insulation while protecting the components inside.

The power input port 20 and the power output port 30 are exposed from the notch of the housing 10. The power input port 20 includes a first power input terminal 21, a second power input terminal 22, and a first ground terminal 23, and the power output port 30 includes a first power output terminal 31, a second power output terminal 32, and a first ground terminal 33.

The first switch unit 60 is configured to be controlled by a user, for example, a common push switch, toggle switch or rotary switch. The input end of the first switch unit 60 is electrically connected to the first power input terminal 21, the output end of the first switch unit 60 is electrically connected to the first power output terminal 31, and a user can directly operate the first switch unit 60 to switch on the circuit, thereby supplying power to the electric device. In other embodiments, the first switch unit may also be configured as a switch unit of an integrated communication module to allow wireless control by a user through a mobile phone, a tablet computer, or a dedicated remote controller.

In this embodiment, the second switch unit 70 is a relay, such as an electromagnetic relay, an input terminal of the second switch unit 70 is electrically connected to the first power input terminal 21, an output terminal of the second switch unit 70 is electrically connected to the first power output terminal 22, and a control terminal of the second switch unit 70 is electrically connected to the processing unit. When the second switching unit 70 receives the trigger signal of the processing unit 40, the coil of the electromagnetic relay obtains a magnetic force to drive the switch to be closed, so that the input terminal of the second switching unit 70 is connected to the output terminal of the second switching unit 70, thereby completing the circuit.

The sensor unit 50 is electrically connected to the processing unit 40, so as to transmit data signals and power signals. When the environmental parameter detected by the sensor unit 50 reaches the threshold value, the processing unit 40 controls the second switching unit 70 to be turned on. Optionally, the sensor unit 50 includes at least one of a gas sensor, a temperature sensor, a humidity sensor, and an air pressure sensor, and is configured to detect environmental parameters such as a contamination degree, an environmental temperature, an environmental humidity, and an air pressure of the gas. In this embodiment, the sensor unit 50 includes a gas sensor, and when the sensor unit 50 detects that the air pollution degree reaches the threshold value, the processing unit controls the second switch unit 70 to be turned on, that is, the second switch unit is automatically turned on, and the electric device (for example, a ventilator) connected to the power output port of the control module can be automatically started in time according to the environmental parameters.

It should be noted that there is some uncertainty in the automatic control. For example, in a normal state, the electric devices are controlled by the processing unit 40, the sensor unit 50, and the second switching unit 70; however, when the sensor unit 50 cannot work normally (for example, is blocked by dust or foreign matter), the electric equipment cannot be turned on automatically, and the present application allows a user to manually control the working state of the electric equipment through the first switch unit 60, so as to prevent the electric equipment from being started. Of course, if the user feels uncomfortable, the second switch unit 70 may be directly turned on when the sensor unit 50 can normally operate but the environmental parameter does not reach the threshold value. It is easily understood that when the second switching unit 70 is manually turned on, the second switching unit 70 is short-circuited.

The housing 10 is provided with a first opening 101 and a second opening 102, and the sensor unit 50 is located in a gas flow path between the first opening 101 and the second opening 102, so that gas flowing in from one of the first opening 101 and the second opening 102 can be detected by the gas sensor and flows out from the other of the first opening 101 and the second opening 102. Preferably, a small fan is further disposed in the gas flow path between the first opening 101 and the second opening 102 for accelerating the air flow and improving the detection accuracy.

The power management unit 80 is electrically connected between the power input port 20 and the processing unit 40, and the power management unit 80 is configured to receive power and supply power to the processing unit 40 and the sensor unit 50.

Optionally, the control module further includes a display unit 90 electrically connected to the processing unit 40, and the display unit 90 is configured to indicate a state of the second switch unit 70 and/or a detection result of the sensor unit. For example, the display unit 90 is an LED lamp.

On the other hand, the present application further provides an electrical system, where the electrical system includes an electrical device and the control module according to any of the foregoing embodiments, a power input port 20 of the control module is connected to an ac power source, and a power output port 20 of the control module is connected to the electrical device. The first power input terminal 21 is used for connecting with a live wire, the second power input terminal is used for connecting with a zero wire, and the first grounding terminal is used for connecting with a grounding wire. Optionally, the electrical device is a ventilation device (e.g., a ventilator), and the sensor unit 50 includes a gas sensor.

Preferably, the power input port 20 is removably connected to the ac power source and the power output port 30 is removably connected to the powered device, where "removably connected" is understood to mean that removal is possible without the use of tools. The sensor unit 50 may include a plurality of sensors, so that the control module can be selectively used for various electric devices, such as a ventilator, a lighting lamp, an air conditioner, and the like.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
