A clamping block 12 is installed at the end of the guide rod 19, and the clamping block 12 is adapted to the mounting groove 16. A gasket 13 is provided on the inner wall of the clamping block 12. A spring 17 is installed on the outer wall of the guide rod 19, and the spring 17 is installed between the clamping block 12 and the mounting frame 18. A limiting frame 20 is installed at one end of the guide rod 19, a movable groove 9 is provided at the bottom of the shell 1, and a handle 7 is provided at the bottom of the clamping block 12, and the handle 7 is adapted to the movable groove 9. An air inlet 10 is provided on one side of the clamping block 12, an air volume adjustment component for adjusting the air volume is provided on one side of the shell 1, and a collection component for collecting waste oil is provided on one side of the air inlet 10;

[0027] When in use, a volute, an impeller and a matching variable frequency motor are provided in the housing 1. At the same time, a processor and a controller are provided in the housing 1. The variable frequency motor is started to drive the impeller to rotate to form a negative pressure to inhale the oil smoke generated during cooking. The smoke exhaust pipe is connected to the connecting port to transport the inhaled oil smoke through the volute for discharge, thereby reducing the range hood during cooking. Before using the device, the control handle 7 is moved into the moving groove 9, and the block 12 can be controlled to overcome the elastic force of the spring 17 and enter the installation groove 16. After the block 12 moves, the air inlet 10 is installed on the housing 1. The position of the air inlet 10 is matched with the block 12. After aligning it with the block 12, the handle 7 is released, and the block 12 is reset by the elastic force of the spring 17, and the edge of the air inlet 10 can be clamped to fix it. The oil smoke can be normally inhaled through the multiple groups of openings in the air inlet 10, and at the same time, it plays a filtering role to prevent the inhalation of foreign matter. At the same time, the waste oil is blocked to prevent it from adhering to the impeller and affecting the use. When the air inlet 10 is fixed, the rubber gasket 13 contacts with the air inlet 10 to make the fixation more firm, and at the same time, buffering can be performed to prevent the air inlet 10 from vibrating and falling when the device is running. After being used for a long time, the air inlet 10 will be attached with a certain amount of oil and dirt, which will cause the opening to be blocked and affect the entry of oil smoke. It is necessary to remove it for cleaning. By controlling the handle 7 to move to the moving groove 9, the block 12 is driven to overcome the elastic force of the spring 17 and be collected into the mounting groove 16 to release the fixation of the edge of the air inlet 10, thereby completing the rapid disassembly and removing the air inlet 10 for cleaning. When moving, the guide rod 19 is moved to the mounting frame 18 to limit the movement trajectory of the block 12. The limit frame 19 is used to prevent the guide rod 19 from falling off the mounting frame 18. After cleaning, the block 12 is controlled to move to quickly install the air inlet 10, which can reduce the difficulty of disassembling the range hood in household use, thereby facilitating cleaning, reducing unnecessary expenses and making it more convenient to use.

A baffle 15 is provided on the outer wall of the rotating shaft 14, and the baffle 15 is adapted to the air inlet 10.

[0029] When in use, the infrared sensor 2 is connected to the processor and controller in the housing 1 through a line. The infrared sensor 2 can detect the amount of oil smoke during use, and the power of the variable frequency motor can be adjusted according to the amount of oil smoke. At the same time, the rotating motor 3 is controlled to start, driving the rotating shaft 14 and the baffle 15 to rotate, and the opening and closing degree of the baffle 15 is adjusted. By adjusting the opening and closing degree of the baffle 15, the air inlet 10 can be blocked according to the amount of smoke, and the space for oil smoke to enter can be increased, so that the air volume can be automatically adjusted in conjunction with the power adjustment of the variable frequency motor;

[0030] The collecting assembly includes an oil collecting box 5, which is adapted to the air inlet 10. A fixing frame 11 is installed at both ends of the oil collecting box 5. The fixing frame 11 has screw holes, through which bolts are inserted to fix it to the bottom of the air inlet 10. An oil drain port is opened in the center of the air inlet 10.

[0031] When in use, the oil collecting box 5 is installed at the bottom of the air inlet 10. When waste oil accumulates at the air inlet 10, it can flow out through the central oil discharge port and flow into the oil collecting box 5 below the oil discharge port for collection. After a period of use, the oil collecting box 5 can be removed for cleaning.

[0032] In order to facilitate the discharge of waste oil, Figure 3 , 5 As shown, the top of the air inlet 10 is designed to be recessed, and the top of the air inlet 10 is designed to be gradually inclined downward from the edge to the center;

[0033] When in use, the inward-recessed air inlet 10 is designed to be gradually inclined downward from the edge to the center, so that when waste oil accumulates, it can flow along the inclination and flow to the center to be discharged from the oil outlet for collection, thereby reducing the accumulation of waste oil and facilitating the collection of waste oil.

[0034] In order to prevent the block 12 from tilting when moving, Figure 4 , 5 As shown, the guide rods 19 are installed in groups of two on each group of blocks 12;
