Technical Field
The utility model relates to a kitchen appliance, in particular to a range hood.
Background
The range hood is a device commonly used in home kitchens and commercial kitchens, and is mainly used for absorbing and discharging oil smoke and smell generated in a cooking process. However, most of the traditional range hoods only have basic oil smoke suction and exhaust functions, and lack an effective oil smoke filtering and purifying mechanism.
Therefore, the existing range hood has the following disadvantages: 1. the existing range hood mainly sucks and discharges the oil smoke generated in the cooking process to the outside through a powerful fan, but does not specifically purify the oil smoke. 2. In the absence of the filtration purification mechanism, even if the oil smoke is inhaled and discharged, a large amount of harmful substances such as Volatile Organic Compounds (VOCs), particulates, etc. may be contained. 3. Directly discharging the oil smoke outdoors may cause environmental pollution, especially in densely populated areas or food preparation areas. 4. Because there is no filter module, oil stain and dirt are easy to accumulate in the range hood, which not only reduces the service life of the equipment, but also increases the maintenance cost and the cleaning difficulty. 5. Because the lampblack is not effectively purified, pungent smell and oil stains possibly remain in a kitchen, and user experience is affected.
In summary, existing range hoods focus mainly on basic absorption and emission of oil smoke, but lack effective filtration and purification mechanisms for oil smoke components. This not only limits the ability of the device to provide a healthy, clean kitchen environment, but may also lead to environmental pollution and increased maintenance burden for the user. Therefore, development of a range hood with effective oil smoke filtering and purifying functions is urgent.
In such a background, a range hood with a detachable filter module has been developed to solve a series of problems faced by the conventional range hood.

Detailed Description
The utility model is described in more detail below with reference to the accompanying drawings. The utility model provides a lampblack absorber which characterized in that: the intelligent smoke-guiding device comprises a main machine 1, wherein an air inlet 2 is formed in the front port of the main machine 1, an air cabinet 3 is arranged at the top of the main machine 1, the air cabinet 3 is communicated with the air inlet 2, a smoke-guiding plate 4 is arranged at the front port of the main machine 1 in a turned-up mode in a covering mode, and the smoke-guiding plate 4 is driven by a power mechanism to open and close; the air inlet 2 is detachably provided with a filter module 5, and the oil fume passes through the filter module 5 and then enters the air inlet 2; the filter module 5 includes an upper cover 51 and a lower cover 52 that are fastened to each other, a filter area 53 is formed between the upper cover 51 and the lower cover 52, a filter device is filled in the filter area 53, and a plurality of ventilation holes 54 penetrate through the upper cover 51 and the lower cover 52.
The air inlet 2 is covered with a filter plate, and the filter module 5 is positioned behind the filter plate.
The filter device is filter cotton, active carbon or an oil filter screen.
The outer circle of the lower cover 52 is provided with a plurality of buckling seats 55, correspondingly, the outside of the air inlet 2 is provided with a plurality of clamping grooves 21, and the filtering module 5 is detachably buckled in the clamping grooves 21 through the buckling seats 55.
At least two buckling seats 55 are arranged and evenly distributed outside the filtering module 5.
The power mechanism is an electric push rod 6, one end of the electric push rod 6 is hinged with the main machine, and the other end of the electric push rod 6 is hinged with the smoke guide plate.
The electric push rod 6 is arranged in the middle of the host.
