Description

Technical Field

[0001] The utility model relates to the technical field of Internet of Things devices, and more specifically, to an Internet of Things exhaust system. Background Art

[0002] Some current air supply and exhaust systems usually use a fixed opening method, such as directly turning on the switch to turn it on when the power is on, and turning it off when the power is off. However, this opening and closing method requires manual operation at a designated location at a certain time, and there is no network control function. Especially in some special scenarios, it is necessary to open and close the system at multiple time periods within a day. The operation is particularly troublesome, making the equipment non-intelligent.

[0003] To this end, we propose an exhaust system based on the Internet of Things. Utility Model Content

[0004] In order to overcome the defects of the existing technology, the utility model provides an Internet of Things exhaust system, which aims to solve the problems in the above-mentioned existing technology.

[0005] The technical solution adopted by the present invention to solve the technical problem is: an Internet of Things exhaust system, including a power switch, wherein the input end of the power switch is respectively connected to a live wire and a neutral wire, and the Internet of Things exhaust system further includes:

[0006] A rotary switch, wherein the input end of the rotary switch is connected in series with the live wire output end of the power switch;

[0007] A network control box, wherein the positive electrode of the network control box is connected in series with the live wire output terminal of the power switch, the negative electrode of the network control box is connected in series with the neutral wire output terminal of the power switch, the network control box is provided with a control output terminal, and the output terminal of the knob switch is connected to the control output terminal;

[0008] The exhaust fan is connected in series with the neutral line output end of the power switch through the negative pole of the intermediate relay, and the positive pole of the intermediate relay is connected in parallel with the live line output end of the power switch, the output end of the knob switch and the control output end.

[0009] In the above-mentioned Internet of Things exhaust system, the exhaust fan and the intermediate relay are connected via an AC contactor.

[0010] In the above-mentioned Internet of Things exhaust system, the number of the knob switches is the same as the number of the exhaust fans.

[0011] In the above-mentioned Internet of Things exhaust system, the power switch is a 24V power switch.

[0012] The beneficial effect of the present invention is that remote control is performed through the network control box, so that the exhaust fan can be turned on and off through network control, without the need for manual operation at a designated location, thereby improving the degree of intelligence. Moreover, when the network control box fails, control can be performed by switching the knob switch to prevent the exhaust fan from being unusable. BRIEF DESCRIPTION OF THE DRAWINGS
