[0029] Specifically, the host temperature sensor 102 and the humidity sensor 103 respectively sense the outdoor temperature and humidity, and send the outdoor temperature and humidity information to the main board control board 101. A control chip is provided on the main board control board 101, and the control chip processes the outdoor temperature and humidity information to assist in controlling the operation of the humidification function of the fresh air humidifier, such as adding water to and draining water from the water storage tank.

[0030] In an embodiment of the present disclosure, the blower motor driver 313 and the exhaust motor driver 314 are integrated on the main board control board 101.

[0031] As Figure 2As shown, the control system according to the present disclosure further includes a controller control system 200, and the controller control system 200 includes a controller control board 201, a display terminal 202, a display terminal driver 203, a water level controller 204, a controller-side temperature sensor 205, and a controller-side humidity sensor 206. The controller-side temperature sensor 205 is used to sense the temperature indoors, and the controller-side humidity sensor 206 is used to sense the humidity indoors. Among them, the input ends of the controller control board 201 are respectively connected to the display terminal driver 203, the controller-side temperature sensor 205, and the controller-side humidity sensor 206, and the output ends of the controller control board 201 are respectively connected to the water level controller 204 and the display terminal driver 203. The controller control board 201 is in bidirectional data connection with the display terminal driver 203.

[0032] In an embodiment of the present disclosure, the display terminal driver 203 and the water level controller 204 are integrated on the controller control board 201.

[0033] Specifically, the controller-side temperature sensor 205 and the humidity sensor 206 respectively sense the temperature and humidity indoors, send the indoor temperature and humidity information to the controller control board 201, and the controller control board 201 then sends the indoor temperature and humidity information to the control chip on the main board control board 101. Indirectly, the control chip processes the indoor temperature and humidity information to assist in controlling the humidification function operation of the fresh air humidifier, such as the water addition and drainage operations of the water storage box.

[0034] Among them, both the main board control board 101 and the controller control board 201 include printed circuit boards.

[0035] As Figure 1 and Figure 2 shown, a data connection is established between the host-side control system 100 and the controller control system 200 through a 2.4GHZ RF transceiver duplex module.

[0036] Those of ordinary skill in the art know that the controller control system 200 can be arranged in different forms at different positions and on different devices. For example, the controller control system 200 can be arranged in the form of a panel on the main body of the fresh air humidifier, can also be arranged on a remote control, or can be bound to a terminal such as a mobile phone in the form of software such as an app.

[0037] Among them, the water level detection component 306 detects the water level in the water storage box and sends a signal indicating high water level, medium water level or low water level to the main board control panel 101. The main board control panel 101 sends a signal indicating opening or closing to the water inlet valve 301 or the drain valve 302 respectively according to the signal sent by the water level detection component 306.

[0038] Specifically, when the humidifier starts to work, the water level detection component 306 automatically detects the water level in the water storage box and sends a signal indicating the water level information to the main board control panel 101. The main board control panel 101 determines whether to open the water inlet valve 301 or the drain valve 302 according to the received signal of the water level information. When the water level information is high water level, the water inlet valve 301 is closed and the drain valve 302 is opened to prevent the water storage box from overflowing. When the water level information is medium water level, both the drain valve 302 and the water inlet valve 301 are closed to keep the water in the water storage box. When the water level information is low water level, the water inlet valve 301 is opened and the drain valve 302 is closed to introduce water into the water storage box.

In actual operation, when the humidifier is not used for a period of time, but there is still water stored in the water storage tray, the control chip on the main board control panel 101 will open the drain valve 302 and start the pumping water pump 305 to pump and discharge the stored water in the water storage tray to avoid water quality corruption due to long-term storage of water in the water storage tray. For example, the control system can be set to open the drain valve 302 and the pumping water pump 305 every 24 hours to discharge the stored water, and then open the water inlet valve 301 to introduce fresh water into the water storage tray.

[0041] Among them, as Figure 1 shown, the host control system 100 further includes a power module 308 and a relay 307, and the output end of the main board control panel 101 is respectively connected to the power module 308 and the relay 307.

[0042] Specifically, the power module 308 can be a DC power source such as a battery or a rechargeable battery, or an AC power source such as a municipal power grid. The host control system 100 is connected to the relay 307 so that the circuit inside the humidifier can play the roles of automatic regulation, safety protection and circuit conversion.

[0043] Among them, as Figure 1As shown, the input and output ends of the main board control board 101 include a plurality of wiring terminals 309, and the electrical components are respectively connected to the main board control board 101 through the plurality of wiring terminals 309. Among them, the wiring terminals 309 are grounded to prevent electric leakage.

[0044] Among them, the number of display terminals 202 is at least one, which can be set on the main body of the fresh air humidifier or on the remote control, and of course can also be a display terminal such as a mobile phone.

[0045] The display terminal 202 includes a liquid crystal display, and the liquid crystal display can display the water level of the water storage box, the temperature and humidity indoors or outdoors, the heat index and the dew point index.

[0046] Among them, the display terminal 202 further includes at least one input button, and the user sends a control signal to the control system through the input button to intervene in the operation of the fresh air humidifier.

[0047] The user can view the environmental data provided on the display terminal and input customized temperature, humidity, air volume and wind speed settings according to their own needs. After receiving these input settings, the control system will adjust the operation of the humidifier accordingly to meet the user's needs.

[0048] In an exemplary embodiment according to the present disclosure, the control signal includes signals for setting the indoor temperature, humidity, water level of the water storage box, indoor air supply wind speed and exhaust wind speed.

[0049] According to another aspect of the present disclosure, a fresh air humidifier is provided, including an air supply outlet, an exhaust outlet, a humidifying film and a water storage box, characterized in that the fresh air humidifier includes the above control system.
