[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See Figures 1 to 3 As shown, a new type of range hood air outlet with an anti-oil leakage rubber ring includes an inclined air outlet 1, the bottom end of the inclined air outlet is integrally formed with an outwardly bent mounting ear 2, and a mounting hole 3 is fixed on the mounting ear. In this embodiment, the above structure is a conventional structure of the prior art and is simply applied, so it is not recorded in detail. The mounting hole is an L-shaped or straight hole, so that the position can be adjusted during installation.

[0022] In actual application, the inner wall of the inclined air outlet is integrally formed with a convex ring 4, and the inner edge of the convex ring is integrally formed with an annular convex edge 5; a position avoidance ring groove is provided between the annular convex edge and the inner wall of the inclined air outlet. During installation, the connecting tube is inserted into the inclined air outlet tube, and the annular convex edge is inserted into the annular slot on the end face of the connecting tube for positioning.

[0023] In actual application, an anti-leakage rubber ring 6 is buckled on the annular convex edge; the anti-leakage rubber ring is a rubber ring or a silicone ring. It has good softness and flexibility. The bottom surface of the anti-leakage rubber ring is provided with an n-shaped card slot 7. In actual application, the thickness of the annular convex edge matches the width of the n-shaped card slot. The annular convex edge is snapped into the n-shaped card slot for positioning. Through the above structure, the annular convex edge is abutted against the annular convex edge through the anti-leakage rubber ring, which improves the sealing of the installation. Moreover, when used for a long time, even if there is a slight deformation, it can be deformed by the anti-leakage rubber ring to ensure the overall anti-leakage effect. It is stable and reliable to use, and has strong applicability and good practicality.

[0024] In actual application, the top edge of the annular convex edge is provided with U-shaped grooves 8 at equal intervals; at the same time, a convex block 9 matching the U-shaped groove is integrally formed on the top wall of the n-shaped slot; during installation, the convex block is inserted into the U-shaped groove for limiting position. The above structure can prevent the oil leakage prevention rubber ring from loosening or shifting after installation, thereby improving the stability and reliability of installation.

[0025] The diameter of the convex ring is integrally formed with a rib 10. This is a conventional structure of the prior art, and a support rod can be installed on the rib to ensure the strength of the overall structure and prevent it from deforming.

[0026] The utility model has positive effects: the structure of the utility model is reasonably arranged, and an annular convex edge is provided to cooperate with an oil leakage prevention rubber ring. After installation, the oil leakage prevention rubber ring is used to improve the overall installation stability and sealing. At the same time, the softness and flexibility of the oil leakage prevention rubber ring can effectively improve the oil leakage and air leakage prevention performance. At the same time, it is also convenient for disassembly and maintenance operations, which is conducive to improving the overall service life. It has strong applicability and good practicality.

[0027] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
