Description

Technical Field

[0001] The utility model belongs to the technical field of range hood filters, and particularly relates to a range hood filter. Background Art

[0002] The range hood filter is a key component installed inside the range hood, mainly used for filtering and intercepting the oil fume and other particulate matters generated during the cooking process. Its structure usually adopts multiple layers of metal meshes intertwined or made of special materials, with good air permeability and oil adsorption. When the oil fume passes through the filter, the oil will be captured by the filter and adhered to its surface, preventing the oil from entering the deep components of the range hood, thus protecting the motor and fan from oil pollution and prolonging the service life of the range hood. At the same time, the filter can also prevent larger foreign objects from being sucked into the range hood, reducing the risk of machine failure and being beneficial to maintaining the cleanliness of the kitchen air.

[0003] After the existing range hood filters are used for a long time, the oil accumulates on the surface and is not easy to slide down into the oil collecting tank. As the use time increases, the accumulated oil is too much. Once it exceeds the bearing capacity of the filter or encounters the condensation condition, it is easy to form oil droplets and drip from the edge or gap of the filter. Therefore, we hope to design a range hood filter with a new structure to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a range hood filter to solve the problems put forward in the above background art.

[0005] The utility model is realized through the following technical solutions: A range hood filter includes: an oil cup, a filter frame, and a filter screen. The oil cup is threadedly connected to the lower end of the filter frame, and the filter screen is movably installed on the upper side of the filter frame. The oil cup includes a cup body and a convex block, and the convex block is arranged at the rear side of the cup body.

[0006] The filter frame includes a base, a connecting part, and a circular frame. There are a plurality of equally distributed connecting parts between the upper side of the base and the lower side of the circular frame.

[0007] The filter screen includes a mesh body and a circle, and the circle is fixed to the upper side of the mesh body.

[0008] As a preferred embodiment, the upper end of the convex block is provided with a rounded corner, the lower end of the convex block is flush with the rear side of the lower end of the cup body, and the thickness of the convex block is not less than 5 mm. In actual use, the inner diameter of the upper side of the cup body is larger than the diameter of the base, which enables all the oil concentrated on the base to be received by the cup body.

[0009] As a preferred embodiment, a ventilation hole is respectively arranged on the left side and the right side of each of the connecting parts. The widths of the ventilation holes and the connecting parts gradually decrease from top to bottom, and the height of the outer end of the lower end of the ventilation hole is greater than that of the inner end.

[0010] As a preferred embodiment, a diversion part is arranged on the outer wall of each of the connecting parts. The diversion part includes a vertical diversion groove, an inclined diversion groove I and an inclined diversion groove II. The diversion part is located in the middle of the outer wall of the connecting part, and the length of the diversion part is less than the height of the connecting part.

[0011] As a preferred embodiment, a plurality of inclined diversion grooves I arranged at an angle of 45 degrees are arranged on the left side of the diversion part. The height of the lower end of each inclined diversion groove I is less than that of the upper end. The upper end of each inclined diversion groove I is communicated with the vertical diversion groove, and the lower end of each inclined diversion groove I is communicated with the right side of a ventilation hole.

[0012] As a preferred embodiment, a plurality of inclined diversion grooves II arranged at an inverted 45-degree angle are arranged on the right side of the diversion part. The height of the lower end of each inclined diversion groove II is less than that of the upper end. The upper end of each inclined diversion groove II is communicated with the vertical diversion groove, and the lower end of each inclined diversion groove II is communicated with the left side of a ventilation hole. The arrangement of the diversion part can guide the grease attached to the outer wall of the connecting part into the filter frame to avoid the accumulation of grease on the outer wall surface of the connecting part.

[0013] As a preferred embodiment, a plurality of fixing columns uniformly distributed in an annular structure are arranged on the upper surface of the circular frame. A plurality of fixing holes uniformly distributed in an annular structure are formed by penetrating downward through the upper surface of the circle. The number, size and distribution position of the fixing holes are matched with the number, size and distribution position of the fixing columns;

[0014] A circular magnet is fixed to the upper end of each of the fixing columns.

[0015] After adopting the above technical solution, the beneficial effect of the utility model is that: by arranging a convex block at the rear side of the cup body, when installing or disassembling the cup body, the user can very conveniently rotate the cup body through the convex block, and the oil cup is not easy to disassemble due to slippery hands caused by oil stains on the surface of the cup body;

[0016] The setting of the filter frame is such that by providing a diversion part on the connecting part, the oil stain will gradually move downward. During the downward movement of the oil stain, it will pass through the vertical diversion groove, the first inclined diversion groove, or the second inclined diversion groove. Whether it is the vertical diversion groove, the first inclined diversion groove, or the second inclined diversion groove, the oil stain on the surface of the connecting part will be guided to the inner wall of the corresponding ventilation hole. Since the height of the outer side at the lower end of the ventilation hole is greater than that of its inner side, when the oil stain is diverted to the lower end of the ventilation hole, it will be diverted to the inside of the base by its inclined structure, and then enter the oil cup for collection, without accumulating on the surface of the connecting part. Without the accumulation of oil stain on the surface of the connecting part, the risk of oil dripping on the filter frame will be reduced. Brief Description of the Drawings
