The internal structure of the common range hood shown in Figure 1, its composition and its shortcomings are as described above, and will not be repeated here.

Figure 2 is an exploded view of the structure of the utility model, as shown in this figure, it can be clearly seen that it mainly includes an electrical box assembly 2 and a switch assembly 3; wherein, the electrical box assembly 2 and the switch assembly 3 is connected through the connector signal line 20; the electrical box assembly 2 includes an electrical box 21 and a circuit board 22, and the circuit board 22 is arranged in the electrical box 21. When assembling, first use the fastener 25 to fasten the circuit board 22 After being fixed on the bottom plate 23 of the electrical box, the electrical box 21 and the bottom plate 23 of the electrical box are locked and fixed by screws 24 . The rear end of the circuit board 22 is provided with several electric wires and signal wire slots 221, and several jacks 211 are also provided at the relative position on the electrical box 21, which can provide different electric wires and signal wires 41, 42, 43, 44, 20 It is inserted into the slot 221 through the jack 211 to conduct the circuit signal of the circuit board 22 .

Connected by different specific wires and signal lines 41, 42, 43, 44, 20, after the user presses the corresponding switch, the information can be transmitted to the circuit board through the signal line, and then the internal operation of the circuit board will transmit the information The wires and signal lines of a specific machine are sent out to make the corresponding machine work.
