However, some existing range hoods require users to adjust the suction power of the range hood according to the concentration and amount of oil smoke generated during cooking, resulting in low adjustment accuracy. This may cause a large amount of oil smoke to be emitted into the kitchen, affecting the normal use of the range hood.
[0004] Therefore, it is necessary to provide a new automatic adjustment ceiling type range hood to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION
[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,in Figure 1 A structural schematic diagram of a preferred embodiment of the automatic adjustment ceiling-mounted range hood provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the regulating assembly shown; Figure 3 for Figure 1 A schematic diagram of the structural connection between the first screw rod and the first connecting block is shown;
[0023] Figure 4 for Figure 1 A schematic diagram of the structural connection between the second screw mechanism and the cleaning wipe is shown. An automatically adjustable ceiling-mounted range hood includes a range hood body 1, a PLC controller 2 disposed on the top of the range hood body 1, a main chassis 3 disposed on the top of the range hood body 1, and a gas sensor 23 disposed on the front surface of the range hood body 1;
[0024] The adjustment component 4 is arranged on the top of the range hood body 1. The adjustment component 4 includes a fan 41, a conveying box 42, an air inlet pipe 43, a main conveying pipe 44 and a suction plate 45. The top of the range hood body 1 is fixedly connected with the fan 41, the air outlet of the fan 41 is connected to the conveying box 42, the air inlet of the fan 41 is connected to the air inlet pipe 43, and the end of the air inlet pipe 43 away from the fan 41 is connected to the main conveying pipe 44. A suction plate 45 is provided on the front surface of the range hood body 1.
[0025] In the specific implementation process, Figure 2 and Figure 3 As shown, the end of the main delivery pipe 44 away from the air inlet pipe 43 is connected to the regulating pipe 5, the outer side of the regulating pipe 5 is slidably connected to the inner wall of the main delivery pipe 44, and the end of the regulating pipe 5 away from the main delivery pipe 44 is connected to the branch pipe 6.
[0026] The outer side of the branch pipe 6 is connected to the side pipe 7, and the end of the side pipe 7 away from the branch pipe 6 is connected to the sliding pipe 8. The outer side of the sliding pipe 8 is slidably connected to the inner wall of the side pipe 7, and the end of the sliding pipe 8 away from the side pipe 7 is connected to the suction disk 45.
[0027] A first screw mechanism 9 is provided on the top of the range hood body 1 , a first connecting block 10 is provided on the outside of the first screw mechanism 9 , and a first slot 11 fixedly connected to the outside of the regulating tube 5 is provided inside the first connecting block 10 .
[0028] A second connecting block 12 is provided on the outer side of the first screw mechanism 9 , and a through hole 13 is formed inside the second connecting block 12 .
[0029] A second card slot 14 is provided inside the second connecting block 12 , a top pipe 15 is connected to the top of the delivery box 42 , a flue 16 is connected to the top of the main box 3 , and the outer side of the flue 16 is connected to the end of the top pipe 15 away from the delivery box 42 .
[0030] It should be noted that: under the action of the gas sensor 23, the oil fume concentration at the range hood body 1 can be detected. After the oil fume concentration exceeds a certain threshold, under the action of the PLC controller 2, the first screw mechanism 9 starts to operate. Under the action of the screw inside the first screw mechanism 9, the first connecting block 10 and the second connecting block 12 can be driven to move in opposite directions, so that the adjusting tube 5 and the sliding tube 8 move, and then the two suction discs 45 can move to the specified position, and then can absorb the oil fume at the range hood body 1. Therefore, under the action of the range hood body 1 and the two suction discs 45, the oil fume can be quickly extracted, and then the oil fume is transported to the inside of the conveying box 42, and then through the top pipe 15, the oil fume can enter the inside of the flue 16, thereby reducing the oil fume concentration at the range hood body 1.
[0031] refer to Figure 1 and Figure 4 As shown, a second screw mechanism 17 is provided at the bottom of the range hood body 1 , a moving block 18 is provided on the outer side of the second screw mechanism 17 , and a top block 19 is fixedly connected to the top of the moving block 18 .
[0032] A fixing frame 20 is fixedly connected to the front surface of the moving block 18 , a side plate 21 is fixedly connected to the rear surface of the fixing frame 20 , and a cleaning wipe 22 is provided on the rear surface of the side plate 21 .
[0033] It should be noted that: when the range hood body 1 is used for a long time, a lot of oil and dirt will adhere to its operation panel and gas sensor 23, causing the second screw mechanism 17 to start operating. Under the action of the second screw mechanism 17, the moving block 18 can move on the outside of the screw, and at the same time, the moving block 18 drives the top block 19 to slide inside the range hood body 1. A sliding groove is provided inside the range hood body 1 for use with the top block 19, so that the movement of the moving block 18 remains stable. At the same time, when the moving block 18 moves, it can drive the fixed frame 20 to move, and then drive the cleaning wipe 22 to move at the control panel, thereby cleaning the control panel.
[0034] The working principle of the automatic adjustment ceiling range hood provided by the utility model is as follows:
[0035] When the staff uses this device to extract oil fumes during cooking, they first start the range hood body 1 through the control panel, and then the oil fumes generated during cooking can be extracted and transported. Under the action of the gas sensor 23, the concentration of the oil fume can be sensed. After the oil fume concentration exceeds a certain threshold, the signal is transmitted to the PLC controller 2. Under the action of the PLC controller 2, the first screw mechanism 9 starts to operate. Under the action of the first screw mechanism 9, the first connecting block 10 and the second connecting block 12 move in opposite directions, and then the adjusting tube 5 and the sliding tube 8 move in opposite directions, so that the two suction discs 45 can move, so that the two suction discs 45 can absorb the oil fume, and then under the action of the fan 41, the oil fume can pass through the conveying box 42 and the top pipe 15 into the interior of the flue 16, and then be transported, so that the oil fume exceeding a certain threshold can be extracted, so that the oil fume residue is reduced.
