In order to further improve the structural strength of the bottom of the air outlet cover, reinforcing plates which are distributed at intervals along the circumferential direction are arranged between the middle annular wall and the outer circumferential wall.
In order to further improve the effect of preventing air leakage and oil leakage, the edge of the smoke outlet extends upwards to form a circumferential retaining wall, and the inner circumferential wall of the air outlet cover is embedded between the circumferential retaining wall and the circumferential convex rib.
Preferably, the circumferential convex rib is circumferentially provided with a breaking part, a lower mounting hole is formed in the breaking position, an upper mounting hole is formed in the corresponding position of the air outlet cover, and screws sequentially penetrate through the upper mounting hole and the lower mounting hole from top to bottom to fix the air outlet cover on the top cover plate.
In order to further connect and fix the air outlet cover and the top cover plate, the peripheral bottom of the air outlet cover is fixed on the top cover plate through screws.
In order to avoid grease from dropping from the edge of the top cover plate, the outer periphery of the top cover plate is turned upwards to form a flanging.
Compared with the prior art, the utility model has the advantages that: this range hood's leak protection wind oil leak structure installs out the fan on the exhaust port of lamina tecti, through the protruding muscle embedding of circumference around the exhaust port in the circumference recess of fan bottom, can make to form closely to cooperate between lamina tecti and the fan, effectively avoids lamina tecti and the junction of play fan to produce air leakage and oil leak phenomenon.

Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 5, the range hood of the embodiment includes a box body 1 and a top cover plate 2 installed on the top of the box body, a smoke outlet 21 is opened on the top cover plate 2, an air outlet housing 3 is installed on the smoke outlet 21, and the bottom of the periphery of the air outlet housing 3 is fixed on the top cover plate 2 through a screw (not shown). The structure is the same as the air outlet cover mounting structure of the existing range hood, and the description is not repeated.
The top cover plate 2 of the embodiment is provided with a circumferential rib 22 protruding upwards around the smoke outlet 21, and a circumferential retaining wall 23 extending upwards is arranged at the edge of the smoke outlet 21. The bottom of the wind-out cover 3 is provided with an inner peripheral wall 32 and an outer peripheral wall 33, an intermediate annular wall 34 is further arranged between the inner peripheral wall 32 and the outer peripheral wall 33, and a circumferential groove 31 is formed between the inner peripheral wall 32 and the intermediate annular wall 34.
When the air outlet cover 3 is arranged on the top cover plate 2, the circumferential convex rib 22 of the top cover plate 2 is embedded in the circumferential groove 31. The inner peripheral wall 32 of the air outlet cover 3 is embedded between the circumferential retaining wall 23 and the circumferential convex rib 22, so that the air outlet cover 3 and the top cover plate 2 can be tightly matched, the sealing effect is achieved, and the effects of air leakage and oil leakage are achieved.
In addition, the circumferential convex rib 22 of the top cover plate 2 is circumferentially provided with a breaking part, a lower mounting hole 24 is formed at the breaking position, an upper mounting hole 38 is formed at the corresponding position of the air outlet cover 3, and screws sequentially penetrate through the upper mounting hole 38 and the lower mounting hole 24 from top to bottom to fix the air outlet cover 3 on the top cover plate 2, so that the mounting structure of the air outlet cover 3 is firmer.
