[0002] In hotel operations, the kitchen is a core area with frequent and large-scale cooking activities. The preparation of a large number of dishes every day generates a lot of oil fumes. If not effectively treated, it will seriously affect the hotel's internal environment and the surrounding air quality. Therefore, it is necessary to use oil fume treatment equipment.

[0003] Currently, Chinese utility model patent CN221684639U discloses a commercial kitchen fume treatment device, including a straight pipe and a smoke inlet. The bottom right side of the straight pipe is connected to the top of the smoke inlet. A cleaning structure is connected to the right side of the inner wall of the straight pipe. A bend is fixed to the top of the straight pipe, and a nozzle is connected to the bottom of the bend. A fume treatment device is connected to the left side of the straight pipe. Top plates are fixed to the four corners of the top of the outer wall of the fume treatment device. Collection structures are connected to the bottom of both the front and rear sides of the straight pipe. By rotating the first screw in the cleaning structure with the help of the handle, the rotating first screw drives the bracket to move to the left. The moving bracket causes the push plate to move to the left along the bottom of the inner wall of the straight pipe, thereby pushing the knocked-down dust into the housing for timely cleaning. This ensures the normal exhaust volume of the commercial kitchen fume treatment device and improves the working efficiency of the commercial kitchen fume treatment device.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of dust being knocked down by the spray nozzles, and the lack of a cleaning structure inside the pipes causing the dust to accumulate at the bottom of the pipes, leading to a decrease in the internal space of the pipes over time and affecting the normal exhaust volume of commercial kitchen fume treatment equipment, thus reducing work efficiency, during use, a large number of oil fume particles, dust and other impurities continuously adhere to the inner wall of the duct, not only reducing the efficiency of smoke intake but also causing oil fumes to accumulate near the smoke inlet, forming stubborn stains. Existing cleaning methods mainly rely on manual cleaning, resulting in a cumbersome, time-consuming and labor-intensive cleaning process. Utility Model Content

[0024] As a technical optimization of this utility model, by setting a guide reset mechanism 8, the guide rod 82 and the guide block 83 can be effectively coordinated, so that the cleaning scraper frame 4 can move smoothly along the direction of the guide rod 82 when moving up and down. This ensures that the cleaning scraper frame 4 always maintains the correct position and angle when cleaning the inner wall of the smoke inlet pipe 2, thereby improving the cleaning effect and ensuring that all parts of the inner wall of the smoke inlet pipe 2 can be effectively cleaned. The reset component 84 is connected to the top two sides of the cleaning scraper frame 4. After cleaning, it can automatically reset the cleaning scraper frame 4 to the initial position using its own elastic force, without the need for manual reset, which greatly improves the convenience and efficiency of the cleaning operation.

[0025] refer to Figure 2 and Figure 3 The reset assembly 84 includes an L-block 841, which is fixedly connected to both sides of the top of the smoke inlet pipe 2. A reset spring 842 is provided at the bottom of the L-block 841. One end of the reset spring 842 is fixedly connected to both sides of the top of the cleaning scraper frame 4, and the other end of the reset spring 842 is fixedly connected to the bottom of the L-block 841.

[0026] As a technical optimization of this utility model, by setting a reset component 84, one end of the reset spring 842 is connected to the top of the cleaning scraper frame 4 and the other end is connected to the bottom of the L block 841. After the cleaning scraper frame 4 is pressed down and moved for cleaning, the elastic potential energy stored in the reset spring 842 is released, pulling the cleaning scraper frame 4 up to reset, realizing the automatic reset function of the cleaning scraper frame 4, which facilitates subsequent cleaning operations and saves manpower and time costs.

[0027] refer to Figure 2 and Figure 3 The protective component 9 includes a support frame 91, which is fixedly installed on both sides of the bottom front and rear sides of the smoke inlet pipe 2. A protective mesh plate 92 is movably connected to the inner wall of the support frame 91, and a pull ring 93 is fixedly connected to the outer side of the protective mesh plate 92.

[0028] As a technical optimization of this utility model, by setting the protective component 9, the protective mesh plate 92 can be movably connected to the inner wall of the support frame 91. It can be easily disassembled and installed by the pull ring 93, making it easy to clean or replace the protective mesh plate 92. The protective mesh plate 92 can block mosquitoes, large food residues and other foreign objects from entering the smoke inlet pipe 2, prevent the smoke inlet pipe 2 from being blocked, ensure that the oil fumes can enter the equipment smoothly for treatment, maintain the normal operation of the equipment, and at the same time reduce the equipment failure that may be caused by the entry of foreign objects.

[0029] refer to Figure 2 and Figure 3A connecting plate 10 is fixedly installed at the bottom of the cleaning scraper frame 4. A brush 11 is fixedly connected to the surface of the connecting plate 10. The number of brushes 11 is set to several groups, and the brushes 11 are made of steel wire.

[0030] As a technical optimization of this utility model, by setting the connecting plate 10 and the brush 11, the cleaning scraper frame 4 can drive the connecting plate 10 to make the brush 11 move accordingly.

[0032] As a technical optimization of this utility model, by setting a protective sleeve 12, the rubber protective sleeve 12 can be placed on the surface of the pressing plate 6. Rubber has good elasticity and friction, which can increase the friction between the operator's hand and the pressing plate 6, prevent the hand from slipping during the pressing operation. At the same time, the elasticity of the rubber can cushion the hand, reduce the fatigue caused by long-term pressing operation, and improve the operator's comfort.

[0033] refer to Figure 1 and Figure 2 A micro motor 13 is fixedly installed at the bottom right side of the smoke inlet pipe 2, and an insect repellent rope 14 is fixedly connected to the output end of the micro motor 13.

[0034] As a technical optimization of this utility model, by setting up a micro motor 13 and an insect repellent rope 14, during the operation of the equipment, the micro motor 13 drives the insect repellent rope 14 to rotate, and the swing of the insect repellent rope 14 drives away mosquitoes and prevents mosquitoes from approaching the smoke inlet pipe 2 and entering the equipment, thus avoiding problems such as pipe blockage and affecting equipment operation caused by mosquitoes entering the smoke inlet pipe 2.

[0035] The working principle and usage process of this utility model are as follows: In use, the cooking fumes generated in the hotel kitchen are first drawn in through the smoke inlet pipe 2. The smoke inlet pipe 2 is connected to the straight pipe 1, and the fumes then enter the fume treatment box 3 on the left side of the straight pipe 1 for purification. Throughout the process, the protective mesh plate 92 is installed on the inner wall of the support frame 91. The protective mesh plate 92 can block mosquitoes, preventing them from entering the inner wall of the smoke inlet pipe 2 and causing accumulation or blockage. Simultaneously, the micro motor 13 is activated to rotate the mosquito-repellent rope, thus preventing mosquitoes from adhering to the surface of the protective mesh plate 92 and causing blockage. Kitchen staff need to regularly check the accumulation of dirt on the inner wall of the smoke inlet pipe 2. When cleaning the inner wall of the smoke inlet pipe 2 is required, the operator presses the top pressing plate 6 with both hands. The pressing plate 6 evenly moves the pressing rod 5 downwards. The pressing rod 5 is fixedly connected to the cleaning scraper frame 4, causing the cleaning scraper frame 4 to move downwards within the smoke inlet pipe 2, thus cleaning the inner wall of the smoke inlet pipe 2. The cleaning process involves scraping and cleaning. Simultaneously, the cleaning scraper frame 4 drives the connecting plate 10, causing the brush 11 to move accordingly. The brush 11 cleans the inner wall of the smoke inlet pipe 2, separating tiny particles or impurities from the smoke inlet pipe 2, thus achieving a convenient cleaning effect and improving the cleaning efficiency of the smoke inlet pipe 2 after use. This makes the cleaning process of the smoke inlet pipe 2 time-saving and labor-saving. During the cleaning process, the connecting block 81 is fixed on both sides of the inner wall of the smoke inlet pipe 2. The guide rod 82 on the inner side of the connecting block 81 cooperates with the guide block 83. The guide block 83 is connected to the inner wall of the cleaning scraper frame 4, ensuring that the cleaning scraper frame 4 moves smoothly along the guide rod 82 when moving up and down, ensuring the accuracy and comprehensiveness of the cleaning. After the cleaning is completed, one end of the return spring 842 is connected to the top of the cleaning scraper frame 4, and the other end is connected to the L-blocks 841 on both sides of the top of the smoke inlet pipe 2. The return spring 842 releases elastic potential energy, pulling the cleaning scraper frame 4 back to the initial position, preparing for the next cleaning.

[0036] In summary, this kitchen fume treatment equipment for hotels, by incorporating a pressing rod 5, a pressing plate 6, a cleaning scraper frame 4, a sealing ring 7, a guide reset mechanism 8, and a protective component 9, allows operators to easily control the cleaning scraper frame 4 to move up and down within the smoke inlet pipe 2 from the top of the straight pipe 1 via the pressing plate 6 and the pressing rod 5. This scrapes and cleans the inner wall of the smoke inlet pipe 2, separating impurities from the pipe and facilitating cleaning. Simultaneously, the sealing ring 7 prevents oil fumes from leaking through the gap between the pressing rod 5 and the straight pipe 1, ensuring the equipment's internal sealing. This solves the problem of large amounts of oil fume particles, dust, and other impurities continuously adhering to the inner wall of the smoke inlet pipe, which not only reduces smoke intake efficiency but also causes oil fumes to accumulate near the inlet, forming stubborn stains. Existing cleaning methods mainly rely on manual cleaning, resulting in a cumbersome, time-consuming, and labor-intensive process.
