Technical Field
[0001] The present application relates to the technical field of oil fume absorption, and in particular to an oil fume absorption device. Background Art
[0002] At present, oil fume absorption devices have become an indispensable electrical equipment in the kitchen. Their main function is to absorb and process the oil fume generated during the cooking process, thereby keeping the kitchen environment clean.
[0003] Traditional oil fume absorption devices usually use a fan combined with a filter. The negative pressure generated by the fan draws the oil fume into the device and then filters it through the filter. However, the filter of this method is prone to clogging and requires frequent cleaning or replacement. The treatment efficiency will drop significantly after long-term use, which cannot meet the needs of modern kitchens for efficient and convenient oil fume treatment.
[0004] To this end, the application provides an oil fume absorption device. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the present application provides an oil fume absorption device, which overcomes the shortcomings of the existing technology and aims to solve the problems in the existing technology.
[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a fume absorption device, comprising a smoke exhaust pipe, a smoke extraction pipe fixedly installed at the bottom of the smoke exhaust pipe, a fan fixedly installed at one end of the smoke extraction pipe, a filter rack slidably connected to the inside of the smoke extraction pipe, a filter mechanism is provided inside the filter rack, a vibrator is fixedly installed on one side of the filter rack, a leakage groove is provided at the bottom of the smoke exhaust pipe, a collection box is fixedly installed at the bottom of the smoke exhaust pipe, and the smoke exhaust pipe and the collection box are connected through the leakage groove.
[0007] By adopting the above technical solution, the fan is turned on to allow the oil smoke to enter the exhaust pipe through the smoke suction pipe. When the oil smoke passes through the filter mechanism, the filter mechanism filters the impurities and oil stains in the oil smoke. After a period of use, the filter mechanism will be clogged. By starting the vibrator to vibrate, it is helpful to help remove impurities and oil stains attached to the filter mechanism, so that users do not need to frequently remove, clean and install the filter mechanism, which greatly improves the convenience of maintenance and is conducive to improving the convenience of oil fume treatment.

When the concentration exceeds the set value, the controller starts the fan to enhance absorption, realizing intelligent control, automatically adjusting the absorption intensity according to the smoke concentration, improving energy efficiency and reducing energy consumption.
[0014] As a preferred technical solution of the present application, the interior of the collection box is slidably connected to a collection pump, and a sponge strip is placed inside the collection pump.

By starting the vibrator 5 to vibrate, it is helpful to help remove the impurities and oil stains attached to the filter mechanism 4, so that the user does not need to frequently remove, clean and install the filter mechanism 4, which greatly improves the convenience of maintenance and is conducive to improving the convenience of oil smoke treatment; the combination of the vertical rod 701, the spring 702 and the block 703 is conducive to clamping the filter frame 3, improving its stability during installation, and at the same time, under the elastic action of the spring 702, the block 703 can be easily detached from 704, thereby facilitating the disassembly and cleaning of the filter frame 3.
[0033] Reference Figure 1-3The filter mechanism 4 includes a metal mesh 401, which is fixedly mounted inside the filter frame 3. An activated carbon layer 402 is fixedly mounted inside the filter frame 3 on one side of the metal mesh 401, and a HEPA filter 403 is fixedly mounted inside the filter frame 3 on one side of the activated carbon layer 402. A smoke concentration detector 10 is fixedly mounted on the inner wall of the smoke exhaust pipe 1 just above the smoke extraction pipe 2. A controller 11 is provided on the front surface of the smoke exhaust pipe 1. The smoke concentration detector 10 is electrically connected to the controller 11, and the controller 11 is electrically connected to the control end of the fan 6. Two sets of guide plates 12 are fixedly mounted on the bottom of the smoke exhaust pipe 1, and the bottom ends of the two sets of guide plates 12 are located at the top of the drain groove 8.
[0034] The metal mesh 401 is used to initially block large particles and protect subsequent filter layers. The activated carbon layer 402 absorbs odors and harmful gases in the oil smoke. The HEPA filter 403 efficiently filters tiny particles, which helps to ensure the cleanliness of the discharged oil smoke.

When the concentration exceeds the set value, the fan 6 is started by the controller 11 to enhance absorption, realizing intelligent control, and automatically adjusting the absorption intensity according to the oil smoke concentration, thereby improving energy efficiency and reducing energy consumption. The guide plate 12 guides the oil stains to fall quickly into the collection pump 13, which helps to improve the collection efficiency of the oil stains and improves the practicality during use.

[0037] Working principle: By turning on the fan 6, the oil smoke enters the exhaust pipe 1 through the smoke pipe 2. When the oil smoke passes through the filter mechanism 4, the filter mechanism 4 filters the impurities and oil stains in the oil smoke. After a period of use, the filter mechanism 4 will be clogged. By starting the vibrator 5 to vibrate, it is helpful to help remove the impurities and oil stains attached to the filter mechanism 4, so that the user does not need to frequently remove, clean and install the filter mechanism 4, which greatly improves the convenience of maintenance and is conducive to improving the convenience of oil smoke treatment. The metal mesh 401 is used to initially block large particles to protect the subsequent filter layer. The activated carbon layer 402 absorbs odors and harmful gases in the oil smoke. The HEPA filter 403 is used to efficiently filter tiny particles, which is conducive to ensuring the cleanliness of the discharged oil smoke.
[0038] The combination of the vertical rod 701, the spring 702, and the clamping block 703 facilitates clamping the filter frame 3, improving its stability during installation.

The smoke concentration detector 10 monitors the oil smoke concentration in real time. When the concentration exceeds the set value, the controller 11 starts the fan 6 to enhance absorption, realizing intelligent control and automatically adjusting the absorption intensity according to the oil smoke concentration, thereby improving energy efficiency and reducing energy consumption.
[0039] At the same time, the sponge strip 14 absorbs the oil and dirt dropped by the filter mechanism 4 due to vibration, and the collecting pump 13 is slidably connected to the collecting box 9, which is convenient for centralized cleaning of the oil and dirt collected in the collecting pump 13, thereby improving the practicality during use; the guide plate 12 guides the oil and dirt to fall quickly into the collecting pump 13, thereby improving the collection efficiency of the oil and dirt and improving the practicality during use;
[0040] In addition, the handle 15 allows the user to easily remove the collection drawer 13 or the filter rack 3, making it easier for the user to perform maintenance and cleaning work. The anti-corrosion coating prevents oil and corrosive gases from corroding the metal mesh 401, the activated carbon layer 402, and the HEPA filter 403, which is beneficial to extending the service life of the metal mesh 401, the activated carbon layer 402, and the HEPA filter 403, while maintaining their filtration efficiency and stability, thereby improving practicality during use.
