Module support 2 is located in electric control cavity 11, and module support 2 has installation site 21. Bluetooth WiFi module 3 includes PCB board 31 and on-board antenna 32, and PCB board 31 is installed in installation site 21, and on-board antenna 32 is installed on PCB board 31, and at least the on-board antenna 32 of bluetooth WiFi module 3 is towards installation port 121. Cover plate 4 is located in installation port 121.
[0028] In the embodiment, the electric control cavity 11 is arranged at the front end of the shell of the range hood main body 1, and is used for mounting part of functional components or electrical components of the range hood. The range hood main body 1 further comprises a top cover plate 13, which is provided with an access opening communicating with the electric control cavity 11, and the maintenance cover plate 12 covers the access opening. When the components in the electric control cavity 11 need to be maintained, the maintenance cover plate 12 can be removed to open the access opening. The module support 2 and the Bluetooth WiFi module 3 can also be installed into the electric control cavity 11 through the access opening of the electric control cavity 11. The Bluetooth WiFi module 3 is used to receive and send Bluetooth signals and WiFi signals (hereinafter collectively referred to as communication signals), and the user's smart terminal is connected with the range hood through the communication signals, so that the user can realize the intelligent interaction with the range hood, and thus the user can control the range hood through the smart terminal and obtain the working condition of the range hood. The module support 2 provides a mounting basis for the Bluetooth WiFi module 3, so that the Bluetooth WiFi module 3 can be conveniently and stably installed in the electric control cavity 11. The PCB board 31 of the Bluetooth WiFi module 3 is installed in the mounting position 21 of the module support 2, and the on-board antenna 32 is installed on the side of the PCB board 31 facing the mounting opening 121. The PCB board 31 is used to connect with the main control board of the range hood to transmit parameter signals and control signals, and the on-board antenna 32 is used to transmit wireless signals converted from the parameter signals and the control signals.
[0029] The on-board antenna 32 faces the mounting opening 121, so that the mounting opening 121 can provide a signal channel for the on-board antenna 32, so that the signals of the on-board antenna 32 can enter and exit the electric control cavity 11 through the mounting opening 121. In this way, the shell of the range hood main body 1 can be prevented from affecting the signal transmission process of the Bluetooth WiFi module 3, so as to improve the signal strength of the Bluetooth WiFi module 3, and improve the interaction effect between the user terminal and the range hood. The cover plate 4 is installed at the mounting opening 121, which can prevent the Bluetooth WiFi module 3 from being exposed to affect the appearance of the range hood main body 1, and can also prevent the Bluetooth WiFi module 3 from being easily contacted and damaged, so as to hide and protect the Bluetooth WiFi module 3. The cover plate 4 can be a plastic cover plate to prevent affecting the signals of the Bluetooth WiFi module 3.
[0030] The mounting structure of the sensor assembly of the utility model, such as Figure 1 and Figure 2As shown, the module support 2 also has a cavity, and an air quality detection module 5 is arranged in the cavity, the covering plate 4 is provided with a detection hole 41 on the part opposite to the mounting position 21, and the air quality detection module 5 detects the air quality through the detection hole 41. The air quality detection module 5 comprises a PM2.5 detection module, the detection hole 41 connects the cavity with the external air environment, and when the air quality detection module 5 works, the air above the smoke machine body 1 enters the cavity through the detection hole 41 and is detected by the air quality detection module 5. It can be understood that the detection hole 41 not only allows the air quality detection module 5 to detect the air, but also allows the signal of the Bluetooth WiFi module 3 to enter and exit the electric control cavity 11, so as to further improve the signal strength of the Bluetooth WiFi module 3.
[0031] The mounting structure of the sensor assembly is shown in Figure 2 and Figure 5 As shown, the cavity is divided into a mounting cavity 22, an air inlet cavity 23 and an air outlet cavity 24.

The on-board antenna 32 is arranged above the air inlet cavity 23 or the air outlet cavity 24. When the air quality detection module 5 works, the external air enters the air inlet cavity 23 from the detection hole 41, flows through the air quality detection module 5 and then flows into the air outlet cavity 24, and finally flows out of the air outlet cavity 24 from the detection hole 41. In this way, a smooth air quality detection path can be formed in the module support 2.
[0032] The mounting structure of the sensor assembly is shown in Figure 1 and Figure 5 As shown, the mounting structure of the sensor assembly further comprises a sealing piece 6, the sealing piece 6 is arranged between the module support 2 and the covering plate 4, the sealing piece 6 has avoiding openings corresponding to the air inlet cavity 23 and the air outlet cavity 24, and the sealing piece 6 allows the air inlet cavity 23 and the air outlet cavity 24 to be connected only through the air quality detection module 5. The part of the sealing piece 6 corresponding to the PCB board 31 is located above the PCB board 31, and the on-board antenna 32 is opposite to the avoiding opening on the sealing piece 6.
[0033] It can be understood that the target detection object of the air quality detection module 5 is the air outside the smoke machine body 1, but after the smoke machine body 1 inhales the oil fume, part of the oil fume may flow to the electric control cavity 11 or even enter the cavity, which affects the detection result accuracy of the air quality detection module 5. The sealing piece 6 can seal and isolate the air inlet cavity 23 and the air outlet cavity 24 from the air environment in the electric control cavity 11, prevent the air in the electric control cavity 11 from entering the air quality detection module 5, and thus ensure that the air detected by the air quality detection module 5 is the air from outside the smoke machine body 1, so as to improve the detection result accuracy of the air quality detection module 5.

After the air flows through the air quality detection module 5, it can continue to flow through the methane sensor and the carbon monoxide sensor for detection of the methane concentration and the carbon monoxide concentration, so that the detection function of the sensor assembly can be improved.
[0035] The installation structure of the sensor assembly, as shown in Figure 2 The side edge of the module support 2 is provided with a support portion in the direction away from the cavity, and the support portion forms the mounting position 21, and the buckle 211 is connected to the support portion.
