In particular, referring to fig. 1 of the drawings, the present invention is based on the principle that charged ions can be directionally deflected in an electric field. Firstly, an oil smoke channel 13 is constructed by using a generating polar plate 11 and a grounding polar plate 12, and an electric field is generated in the oil smoke channel 13; then, an ion generating component 3 is arranged at an inlet of the constructed oil smoke channel 13, the ion generating component 3 continuously emits charged ion groups to the inlet of the oil smoke channel 13, and the ion groups are attached to oil smoke molecules and enter the oil smoke channel 13 along with oil smoke; finally, the oil smoke entering the oil smoke channel 13 will deflect toward the polar plate on one side under the action of the electric field because of the electrification of the ions attached to the oil smoke, and then the oil smoke is finally adsorbed and captured by the oil smoke adsorbing member 2 on the corresponding polar plate. When the oil smoke adsorbing member 2 adsorbs oil smoke to be saturated, the new oil smoke adsorbing member 2 is replaced.

Based on the principle that charged ions can generate directional deflection in an electric field, in the embodiment, the ion generating assembly 3 emits positive charge ion groups, so that oil smoke molecules are deflected to the grounding polar plate 12, and at least the oil smoke adsorbing piece 2 is arranged on the grounding polar plate 12; meanwhile, in order to avoid that part of the oil smoke may be adsorbed on the generating polar plate 11 when the concentration of the oil smoke is high, the oil smoke adsorbing member 2 may be provided on the generating polar plate 11.

The oil smoke adsorption mechanism of the utility model realizes the collection of oil smoke by electrifying the oil smoke molecules and combining the electric field to make the oil smoke molecules generate directional deflection, and compared with the existing air flow suction, the oil smoke adsorption mechanism has the advantages of no noise and no mechanical vibration, and improves the user experience; simultaneously the utility model discloses utilize the oil smoke adsorbent spare on the polar plate to collect the oil smoke and oil smoke adsorption spare 2 is removable, and then need not to clear up components such as polar plate specially, has alleviateed user's oil smoke cleaning work.

Preferably, the oil smoke adsorbing member 2 is an oil absorbing paper, and the oil absorbing paper is attached to the surface of the generating electrode plate 11 and/or the grounding electrode plate 12. The oil absorption paper is light in weight, convenient to install and use, easy to obtain and low in use cost. In addition, the oil absorption paper can adopt a multilayer structure, the surface layer is an oil smoke absorption layer, the bottom layer is an oil separation layer (such as a plastic film), and the oil separation layer can prevent oil stains from soaking the oil absorption paper and remaining on the polar plate. Furthermore, a plastic film (or other materials for resisting water and oil) is used as an oil-separating layer of the oil-absorbing paper, the oil-absorbing paper can be directly attached to the pole plate by water, similar to attaching a window decoration on glass by water, and the oil-absorbing paper is attached to the pole plate by utilizing atmospheric pressure.

Further, the oil absorbing paper is attached to the surface of the generating plate 11 and/or the grounding plate 12 by means of adhesive fixation or clip fixation. The adhesive can be fixed most directly by adopting a corresponding fixing mode according to specific requirements, but the adhesive type needs to be easy to paste or tear and preferably has no residue; the clamp can adopt a clamp to clamp the edge of the oil absorption paper on the polar plate, and the clamp can also adopt a magnet to be adsorbed on the polar plate, so that the oil absorption paper is tightly pressed on the polar plate.

Further, referring to fig. 1 of the drawings, two sides of the ground electrode plate 12 are provided with generating electrode plates 11 and form two oil smoke channels 13, and the inlets of the two oil smoke channels 13 are provided with the ion generating assemblies 3. Two or more oil smoke channels 13 are provided, mainly for improving the effect of oil smoke adsorption. Firstly, a plurality of channels are utilized to disperse oil smoke, so that the phenomenon that the oil smoke in a single oil smoke channel 13 is too high in concentration and cannot be absorbed completely is avoided; secondly, on the basis of a certain size of the range hood, the design of the plurality of oil smoke channels 13 can reduce the width of a single oil smoke channel 13, and avoid overlong adsorption movement path of oil smoke molecules caused by overlarge width, thereby avoiding that the oil smoke is not adsorbed in the process of flowing outwards because of overlong adsorption movement path.

Further, referring to fig. 1 of the drawings, along the direction in which the oil smoke channel 13 extends outwards, the side surface of the generating polar plate 11 and/or the grounding polar plate 12 corresponding to the oil smoke channel 13 is an inclined surface inclined to the oil smoke channel 13. For example, the ground plate 12 shown in fig. 1 is entirely in an inverted trapezoidal structure having a large upper surface thickness and a small lower surface thickness, thereby forming a side surface slope. On one hand, the inclined surface can increase the surface area and improve the adsorption capacity; on the other hand, the inclined plane has certain blocking effect on the oil smoke, so that the oil smoke can be fully contacted with the oil smoke adsorption piece 2 on the surface of the polar plate, and the adsorption effect is improved.

Further, referring to fig. 1 of the drawings, a smoke sensor 4 for detecting the concentration of smoke is further disposed at an inlet of the smoke channel 13, and the smoke sensor 4 is electrically connected to the smoke adsorbing assembly 1. The oil smoke adsorption mechanism further comprises a controller, the controller is electrically connected with the smoke sensor 4 and the oil smoke adsorption component 1 respectively, and the smoke sensor 4 is indirectly and electrically connected with the oil smoke adsorption component 1 through the controller. The smoke sensor 4 can detect in real time and feed back the concentration value of the oil smoke to the controller, the voltage range of the generating polar plate 11 can be controlled after the controller analyzes, the generating polar plate 11 uses low-grade voltage when the oil smoke concentration is low, and the generating polar plate 11 uses high-grade voltage when the oil smoke concentration is high, so that different conditions are matched, and energy is reasonably saved.

Further, the soot absorption mechanism is disposed above the cooking apparatus, and the soot passage 13 extends outward in a direction opposite to the direction of gravity. Because the molecules of the oil smoke are lighter than air, the oil smoke floats upwards under the action of the heat effect on the cooking stove, so that the oil smoke adsorption mechanism does not need other power mechanisms to drive the oil smoke to flow, and the silence is ensured.

Example 2

This embodiment is an improvement on the basis of embodiment 1, and reference is made to embodiment 1 for part of the same contents, which is not described again in this embodiment.

The winding shaft 6 is mainly used for facilitating the detachment of the oil absorption paper, and after the oil absorption paper is saturated with oil stains, the oil absorption paper is difficult to operate because the surface of the oil absorption paper is full of oil stains and the oil absorption paper does not have a rigid structure when a user replaces the oil absorption paper. At this time, the oil absorption paper can be wound into a paper roll by rotating the winding shaft 6, on one hand, the surface layer of the oil absorption paper absorbing oil stains can be rolled into the interior to roll the clean bottom layer to the outside, on the other hand, the oil absorption paper can be wound into the paper roll to increase the rigidity of the structure, and on the two aspects, the oil absorption paper can be conveniently taken by a user and the oil stains are prevented from being scattered and dropped. When the user takes off the paper roll, the user can take out the paper roll by holding the paper roll and moving the paper roll along the axial direction of the winding shaft 6.

In addition, referring to fig. 2 of the drawings, the mounting groove 121 is configured as a circular arc groove matched with the shape of the paper roll, and can play a role in assisting the oil absorbing paper to wind. Specifically, when the oil absorbing paper is wound on the winding shaft 6 to a certain degree, the paper roll formed by the oil absorbing paper contacts the groove wall of the mounting groove 121, so that the groove wall of the mounting groove 121 can reversely press the paper roll, and the paper roll is wound more tightly without loosening. One end of the winding shaft 6 can be hinged with the corresponding mounting seat 122, and the other end of the winding shaft is movably connected with the corresponding mounting seat 122 through a buckle, so that the paper roll can be conveniently taken down after the oil absorption paper is wound.

Further, referring to fig. 2, a driving assembly 7 is further connected to the winding shaft 6, and the driving assembly 7 is used for driving the winding shaft 6 to rotate. The driving assembly 7 adopts a rope driving mode, and includes a winding wheel 71 (disposed inside the mounting seat 122 to isolate oil stains) coaxially disposed with the winding shaft 6, a driving wire 72 wound around the winding wheel 71, and a driving wheel 73 for reversing the driving wire 72, wherein the driving wire 72 and the driving wheel 73 are disposed inside the ground plate 12 to isolate oil stains, and the driving wire 72 is reversed from the winding wheel 71 via the driving wheel 73 and then extended out of the range hood through a through hole on the ground plate 12. When the user operates, the user only needs to pull the driving wire 72 outwards to rotate the winding shaft 6 to wind the oil absorbing paper.

The reset mechanism may also be an elastic member such as a torsion spring disposed on the winding wheel 71, and when the driving wire 72 is pulled to rotate the winding wheel 71, the torsion spring is wound and compressed, and then the elastic potential energy of the torsion spring can drive the winding wheel 71 to rotate in the reverse direction to reset and rewind the driving wire 72.

Further, the spool is divided into two parts by the mounting opening 61, referring to the left and right parts in fig. 2, one of the two parts is used as the main body part of the spool fitting mounting seat 122, and the other part is used as the movable part hinged with the main body part, that is, one end of the movable part is hinged with the end part of the main body part, and the other end can be movably clamped with the main body part. This allows the movable portion to be rotated open by the hinge structure to open the mounting opening 61, facilitating the mounting of the oil absorbing paper. In addition, the size of the mounting opening 61 can be reduced to match the thickness of the oil absorption paper or the size of the mounting opening 61 is slightly smaller than the thickness of the oil absorption paper, so that the oil absorption paper can be clamped to assist in mounting the oil absorption paper.

In addition, referring to fig. 2, the winding reel 6 in the present embodiment is disposed in the middle of the ground plate 12, and may be disposed at an upper portion, a lower portion or other positions according to actual situations, or a plurality of winding reels 6 may be disposed. Of course, the orientation of the spool 6 can be adjusted, for example, vertically as shown in FIG. 2.
