Under the sufficient prerequisite of above-mentioned cooperation structure precision, all cooperate the connection through the mode of mechanical joint between vertical apron 4, horizontal roof 5, filter 9, left side board 1 and the right side board 7, the condition is as follows in the concrete cooperation connection:

the connection between the vertical cover plate 4 and the horizontal top plate 5 is realized by the mutual matching of the T-shaped groove 4A and the T-shaped block 5A at the corresponding position.

The connection between the filter plate 9 and the horizontal top plate 5 and between the vertical cover plate 4 is realized by the mutual matching of the strip-shaped rectangular block 9A and the rectangular groove 5D and the long rectangular groove 4B which are arranged at the corresponding positions.

The connection between the left side plate 1 and the vertical cover plate 4 is realized by the mutual matching of a small rectangular groove 1D and a small L-shaped block 4D at a corresponding position, and the connection between the left side plate 1 and the horizontal top plate 5 is realized by the mutual matching of a small U-shaped groove 1C and a rectangular block 5B at a corresponding position; the structure on the right side plate 7 is the same as that of the left side plate 1, and the connection condition of the right side plate 7, the vertical cover plate 4 and the horizontal top plate 5 is completely the same as that of the left side plate 1, the vertical cover plate 4 and the horizontal top plate 5.

In order to ensure the structural stability of the left side plate 1 and the right side plate 7, the lower through hole 5C on the horizontal top plate 5 coincides with the axis of the upper through hole 1B at the corresponding position of the left side plate and the right side plate, and the left positioning block 2 and the right positioning block 6 can be inserted into the circular holes at the corresponding positions to prevent the side plates from sliding.

The front parts of the left side plate 1 and the right side plate 7 are provided with rectangular sliding grooves 1A, and the large panel 11 can be just connected with the left rectangular groove and the right rectangular groove; the small panel 10 can be connected with the large panel 11 through the U-shaped sliding groove 11A on the large panel 11, and the small panel 10 can freely move up and down along the U-shaped sliding groove 11A for a certain distance.

The positioning block 15 is made of a non-toxic and elastic material, and can be clamped at any position on the U-shaped sliding groove 11A in the large panel. When the range hood works, the small panel 10 can be positioned by the positioning block 15 after moving upwards for a certain distance along the U-shaped sliding groove 11A, when the range hood does not work, the power supply is turned off, the positioning block is taken down, and the small panel can return to the original position.

A plurality of circular filter screens 12 are arranged on the filter plate 9, the circular filter screens 12 are placed on the annular groove openings 9B, and the circular filter screens do not need to be additionally fixed due to the action of gravity. Circular filter screen 12 lower extreme elastic material parcel, circular filter screen 12 can be adsorbed tightly on the filter when lampblack absorber work, prevents that the filter screen aversion from damaging other parts of lampblack absorber.

The circular filter screen 12 is provided with a plurality of compact small holes which can filter oil smoke well so as to reduce the damage of oil stains to a motor system and a rotating impeller.

The filter plate is provided with a plurality of strip-shaped guide grooves 9C which can guide condensed oil drops to prevent oil stains from being stained on the rotary impeller and the volute.

The oil cup 8 located at the lowest part of the range hood can be matched with the long U-shaped groove 4C on the vertical cover plate 4 and can freely move left and right, and oil drops flowing down along the strip-shaped guide groove 9C can be collected by the oil cup 8 in working.

A layer of protective cover is arranged outside a motor system 3 of the range hood, so that the range hood has a sound insulation effect, and the motor can be protected from being interfered and influenced by an external greasy environment.

All key parts of the range hood are subjected to fillet treatment, the appearance is attractive, and the projecting edges and corners can be prevented from damaging people.

The working process is as follows:

when the range hood works, namely, when the range hood is used for cooking or stir-frying, the power switch is turned on, and the motor shaft of the range hood rotates to drive the rotating impeller 14 to rotate to absorb oil smoke. The small panel 10 is moved to an appropriate height along the slide groove of the large panel 11 and temporarily positioned by the positioning block 15. After leaking out of the air inlet of the range hood, the kitchen oil smoke starts to be sent into the air inlet, penetrates through the circular filter screen 12 on the filter plate and is filtered by the circular filter screen holes, and accordingly the oil smoke is primarily purified. Finally, the oil stain flows into the oil cup 8 below along the guide groove on the filter plate, and harmful flue gas is thrown out to the flue above by the rotary impeller 14 and finally discharged to the outside.

The dismounting process:

when the range hood needs to be disassembled, the sequence of disassembling in sequence is positioning block → small panel 10 → large panel 11 → left positioning block 2 → right positioning block 6 → left side plate 1 → right side plate 7 → filter plate 9 → horizontal top plate 5 → circular filter screen 12; the panel and the filter screen which are stained with oil stains can be thoroughly cleaned after being disassembled, the parts are installed back after the cleaning is finished, and the installation sequence is just opposite to the disassembling steps, and the method comprises the following steps: circular screen 12 → horizontal top plate 5 → filter plate 9 → left side plate 1 → right side plate 7 → left locating piece 2 → right locating piece 6 → large panel 11 → small panel 10 → locating piece.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
