Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a centrifugal oil mist processor, comprising an oil mist processor body 1 and an exhaust fan 5 installed on the inner side of the oil mist processor body 1, a filter cartridge 2 is installed on the top surface of the oil mist processor body 1, and an adjustable air inlet assembly 3 is installed on the bottom surface of the oil mist processor body 1. When used later, the oil mist processor body 1 can be installed on the suction port of the external processing equipment, and then after the exhaust fan 5 is started, the oil mist generated during the processing of the external processing equipment can be sucked into the oil mist processor body 1, and then the purified air is discharged after being filtered through the filter cartridge 2, and the oil will be adsorbed by the multi-layer filter cotton in the filter cartridge 2, and the adjustable air inlet assembly 3 includes a movable tube 32 and a fixed tube 31 fixed on the bottom surface of the oil mist processor body 1, the movable tube 32 is movably installed at the bottom of the fixed tube 31, and the top end of the movable tube 32 is slidably inserted into the inner side of the fixed tube 31, and a limiting structure 33 is also arranged between the fixed tube 31 and the movable tube 32;

[0022] The limiting structure 33 includes a movable block 331 movably arranged on the outer surface of the fixed tube 31, a limiting rod 332 is fixed to the side of the movable block 331, and a plurality of limiting slots 333 corresponding to the limiting rod 332 are evenly provided on the left side surface of the movable tube 32, and the end of the limiting rod 332 penetrates into one of the limiting slots 333, so as to stably limit the movable tube 32. The limiting structure 33 also includes an inner groove 334 opened on the left inner side of the fixed tube 31, and an inner sliding block 336 and a spring 337 are provided in the inner groove 334. Two connecting rods 335 are fixed on one side of the inner sliding block 336, and the ends of the two connecting rods 335 are both penetrated to the outer side of the fixed tube 31 and fixed to the movable block 331. Under the pushing action of the spring 337, the movable block 331 can always be in close contact with the outer surface of the fixed tube 31 during daily use, thereby ensuring that the end of the limiting rod 332 is stably stuck in the limiting slot 333, ensuring the installation stability of the movable tube 32, and then The spring 337 will push the inner slider 336 back and reset it, and the connecting rod 335 will pull the movable block 331 back, so that the end of the limiting rod 332 can be stuck in the limiting slot 333 at other positions, and the movable tube 32 can be limited again, thereby realizing the adaptive adjustment of the length of the adjustable air inlet assembly 3 to meet different installation requirements and installation environments.

[0023] Among them, a circular limiting groove is opened on the inner wall of one side of the inner groove 334, one end of the spring 337 is inserted into the circular limiting groove, and the other end of the spring 337 is fixed to the inner slider 336 to ensure the installation stability of the spring 337.

[0024] Among them, a guide block 34 is fixed to the inner wall of the fixed tube 31, and a guide groove 35 corresponding to the guide block 34 is opened on the surface of the movable tube 32. The guide block 34 is located in the guide groove 35, which can play a guiding and limiting role when the movable tube 32 slides up and down to adjust the height, thereby preventing the movable tube 32 from rotating.

[0025] A left through hole is formed on the left side surface of the fixing tube 31 , and the left through hole corresponds to the limiting rod 332 , so that the limiting rod 332 can pass through smoothly.

[0026] Among them, two fixing legs 4 are symmetrically welded on the bottom surface of the oil mist processor body 1, and the bottom ends of the fixing legs 4 are provided with reserved mounting holes, and the fixing legs 4 are used to subsequently fix the oil mist processor body 1 on external processing equipment.

[0027] Example 2

[0028] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that a rubber sealing ring 36 can be provided to play a sealing role between the movable tube 32 and the fixed tube 31.

[0029] Specifically, the adjustable air inlet assembly 3 also includes a rubber sealing ring 36, which is installed on the top surface of the movable tube 32, and the top of the rubber sealing ring 36 is in close contact with the inner wall of the fixed tube 31. The rubber sealing ring 36 can play a sealing role between the movable tube 32 and the fixed tube 31 to prevent oil mist leakage. In addition, since the rubber sealing ring 36 is installed on the movable tube 32, when the height of the movable tube 32 is adjusted later, the rubber sealing ring 36 will also move accordingly to keep the seal at all times. The bottom end of the rubber sealing ring 36 is inserted into the movable tube 32. The inner side of the movable tube 32 is provided with two T-shaped clamp heads 361 on the bottom surface of the rubber sealing ring 36. The inner wall of the top end of the movable tube 32 is symmetrically provided with two T-shaped slots 321 corresponding to the T-shaped clamp heads 361. The T-shaped clamp heads 361 are embedded in the T-shaped slots 321. The T-shaped clamp heads 361 and the rubber sealing ring 36 are both made of fluororubber. When installing, first insert the bottom end of the rubber sealing ring 36 into the inner side of the movable tube 32, and then squeeze the T-shaped clamp heads 361 into the T-shaped slots 321, so as to achieve stable installation of the rubber sealing ring 36.
