When cooking and frying in daily life, a large amount of oil smoke and vapor can be produced by an oil pan and a steamer, and because the room is a relatively closed space, if ventilation is not timely performed, not only can kitchen smoke diffuse, but also other places in the room communicated with the kitchen can be influenced by moist vapor and oil smoke filled with oil drop particles. Therefore, an exhaust fan is generally installed in a room, and a range hood must be installed in a kitchen.
Various exhaust devices such as a ventilator or a range hood and the like can form negative pressure at the air inlet when working, and the generated oil smoke and water vapor are sucked away and transferred to the outdoor along an exhaust pipeline under the action of indoor atmospheric pressure.
When various exhaust devices such as the ventilating fan and the range hood operate, negative pressure is formed in a local space in a room, so that part of air in the room is sucked to the outside. Because the air in each room is circulated and the indoor space is relatively sealed, the air pressure in the whole room is lower than the normal air pressure outside when the exhaust equipment works. The prior sewer of a toilet and a kitchen isolates the circulation of indoor air and air in the sewer through water stored in a water return pipe. However, when the indoor negative pressure is too high, the atmospheric pressure difference between the normal atmospheric pressure in the sewer and the indoor negative pressure exceeds the gravity of water stored in the water return pipe, the water return pipe communicated with the sewer fails, and the gas with pungent odor and even pathogenic bacteria in the sewer can enter the room, so that serious consequences are caused.

When the exhaust equipment works, the socket electric control board 11 in the conversion socket 1 detects the working current of the exhaust equipment and sends a signal to the electric control device 3 through the wireless transmission module 12, the air supply electric control board 31 in the electric control device 3 receives the signal through the wireless receiving module 32 and controls the guide rail telescopic motor 241 to start, so that the guide rail connecting board 245 is driven to move towards the direction of the front panel 25 through the structures of the disc 242, the connecting rod 243 and the fixing rod 244, the front panel 25 is further pushed to be far away from the shell 21, the passage of air from the outdoor to the indoor is opened, then the air supply electric control board 31 controls the axial flow fan 23 to start, the effect of sending the outside air into the indoor to balance the negative pressure caused by the exhaust equipment in the indoor, and the effect of preventing the child gas with pungent odor in the sewer from entering the indoor is achieved.
The implementation principle of the above embodiment is as follows:
the front and rear chucks 212 and 211 of the housing 21 of the ventilating device in the ventilating system are used to fix the air blowing means 2 to a window or a wall so that one end of the housing 21 near the louver 221 is located outdoors and one end of the housing 21 near the front panel 25 is located indoors. After the exhaust device is installed and put into use, when people turn on various exhaust devices such as a ventilator or a range hood, the exhaust device is powered on by the conversion socket 1 and the original indoor socket, so when the exhaust device works, the socket electric control board 11 of the conversion socket 1 can detect the current when the exhaust device works. At this time, the wireless transmission module 12 of the conversion socket 1 sends a signal, the signal is received by the wireless receiving module 32 of the electric control device 3, and after the wireless receiving module 32 receives the signal, the air supply electric control board 31 of the electric control device 3 firstly opens the shutter 221 in the protection component 22, so that the air inlet channel is smooth; then, the rail extension motor 241 is started to rotate the disc 242, and the rail connecting plate 245 is pushed to move along the axial direction of the axial flow fan 23 toward the direction of the front panel 25 by the mechanism that the disc 242 is driven and the connecting rod 243 is driven. Since the front panel 25 is connected to the panel moving rail 246, the rail connecting plate 245 pushes the panel moving rail 246 to move, and eventually pushes the front panel 25 to move in a direction away from the louver 221 along the axial direction of the axial flow fan 23.
When the front panel 25 is moved in place, that is, the indoor space is communicated with the outdoor space, at this time, the air supply electric control board 31 of the electric control device 3 turns off the guide rail extension motor 241 and starts the axial flow fan 23, and the outdoor air is filtered by the filter screen 222 and then is sent into the indoor space to balance the indoor negative pressure. Also, the socket electronic control board 11 of the switching socket 1 can detect a change in current when the exhaust apparatus is operated. When the oil smoke is large, people can start the powerful mode of the range hood, at the moment, the exhaust speed of exhaust equipment is higher, the working current is increased, the socket electric control board 11 of the conversion socket 1 transmits the signal to the air supply electric control board 31 of the electric control device 3 through the wireless transmission module 12 and the wireless receiving module 32, the air supply electric control board 31 immediately increases the working strength of the axial flow fan 23, and the air inlet speed is increased to balance indoor negative pressure.
After the exhaust equipment works, the socket electric control board 11 of the conversion socket 1 detects that the working current of the exhaust equipment is zero, the air supply electric control board 31 of the electric control device 3 firstly closes the axial flow fan 23 and restarts the guide rail telescopic motor 241, so that the guide rail telescopic motor 241 reversely rotates, the front panel 25 is further pulled towards the shutter 221 along the axial direction of the axial flow fan 23, finally the front panel 25 is contacted and attached to the shell 21 of the air supply device 2, the air supply channel is closed, and finally the shutter 221 is closed to completely isolate the indoor space from the outdoor space. At this time, the air supply device 2 completes a working cycle, and when a signal sent by the wireless transmission module 12 of the next switching socket 1 is detected, the above steps are cycled to continue the operation.
