[0052] When removing the baffle 300, press the locking block 620 so that the locking block 620 is embedded in the mounting groove 521, thereby facilitating the movement of the sliding rod 520, causing the telescopic rod 500 to shorten and move away from the support plate 320, thereby facilitating the removal of the baffle 300 and the filter plate 310 from the housing 100, and facilitating the cleaning or replacement of the filter plate 310 and the baffle 300.

[0053] Reference Figure 1 and Figure 7 The outer walls of the housing 100 on both sides along its width are provided with connection grooves 150. The length of the connection grooves 150 is consistent with the length of the housing 100. The connection grooves 150 are located at the bottom end of the housing 100.

[0054] When disassembling the oil collecting tank 110, move the oil collecting tank 110 along the length direction of the oil collecting tank 110 so that the connecting block 111 slides along the length direction of the oil collecting tank 110 and is connected in the connecting groove 150, so that the oil collecting tank 110 is away from the shell 100, thereby facilitating the cleaning and replacement of the oil collecting tank 110.

[0055] The operating principle of a range hood with an adjustable smoke intake range according to an embodiment of the present application is as follows: During operation, the first motor 400 drives the telescopic rod 500 to rotate, causing the support plate 320 and the baffle 300 to rotate along with the telescopic rod 500, moving the baffle 300 away from the smoke inlet 120 and allowing the filter plate 310 to be embedded within the smoke inlet 120. When the cooking range is small, the power of the fan 210 is reduced, and the three-way valve controls the connection between the first tube 160 corresponding to the cooking position and the smoke exhaust duct 200, while disconnecting the other first tube 160 from the smoke exhaust duct 200. The baffle 300 is rotated to open the smoke inlet 120 corresponding to the cooking position and close the remaining smoke inlets 120. The fan 210 operates, forcing oil smoke into the cavity through the smoke inlet 120. The oil smoke is then discharged from the housing 100 along the first tube 160 and the smoke exhaust duct 200. This ensures that even with reduced power, the range hood's suction force on oil smoke remains unchanged, thereby reducing energy waste.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
