[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-6 This range hood with gas leak alarm and air purification detection includes a body 1, on which are installed: Controller 2 and control panel 3 are electrically connected to enable bidirectional communication between them. Alarm device 4 is used to detect whether the gas leak near the range hood has reached the alarm threshold and danger alarm threshold. Control panel 3 is electrically connected to alarm device 4. Alarm component 5 is used to issue alarm prompts; control panel 3 is electrically connected to alarm component 5. Air detector 6 is used to detect whether the concentration of particulate matter near the range hood has reached the preset working threshold. Control panel 3 is electrically connected to air detector 6. Fan 7 is used for ventilation. Controller 2 is electrically connected to fan 7 to control the start and stop of fan 7.

[0024] The alarm device 4 is equipped with a gas-sensitive sensor or laser sensor for detecting gas concentration, such as a natural gas semiconductor gas-sensitive sensor. When a gas leak occurs in the operating environment and reaches the alarm threshold or danger alarm threshold, the range hood will issue an audible and visual alarm to achieve the purpose of gas leak alarm.

[0025] The air detector 6 is equipped with a gas sensor or laser sensor for detecting particulate matter concentration. When the ambient air particulate matter level reaches the preset working threshold, the smoke machine sends a working reminder signal and starts the fan 7 to replace the air.

[0026] The alarm device 4 is equipped with an alarm for issuing an alarm.

[0027] The control panel 3 is equipped with a display screen 8 for displaying gas leak alarm information and gas leak hazard alarm information. The display screen 8 is equipped with a function indicator light 12 for indicating that the particulate matter concentration has reached the preset working threshold. The control panel 3 is electrically connected to the display screen 8.

The buzzer and the indicator light are respectively mounted on the control panel 3, and the control panel 3 is electrically connected to the buzzer and the indicator light respectively.

[0029] The working principle of this range hood with gas leak alarm and air purification detection is as follows: 1. When the range hood is in operation or standby mode, if the alarm device 4 detects a natural gas leak near the range hood and the leak reaches the alarm threshold (0.5%~300%VOL), the alarm will sound. The gas sensor or laser sensor will send a signal to the control panel 3, the buzzer will sound an alarm, the indicator light will flash, the display screen 7 will display "CH4" gas leak alarm information, the control panel 3 will send a signal to the controller 2, and the controller 2 will control the fan 7 to work to discharge the natural gas to the outside. 2. When the range hood is in operation or standby mode, if the alarm device 4 detects a natural gas leak near the range hood and the leak reaches the danger alarm threshold (≥300% VOL), the alarm will sound. The gas sensor or laser sensor will send a signal to the control panel 3, the buzzer will sound an alarm, the indicator light will flash, the display screen 7 will display the "119" gas leak danger alarm information, the control panel 3 will send a signal to the controller 2, the controller 2 will cut off the high-voltage circuit of the range hood, and the fan 7 and heating components will stop working.

[0030] 3. When the range hood is in operation or in standby mode, the air detector 6 monitors the concentration of particulate matter near the range hood in real time. When the concentration of particulate matter reaches the preset working threshold, the "PM2.5" function indicator light on the display screen 8 will light up, and the controller 2 will control the fan 7 to start working to actively ventilate the kitchen environment.
