The two ends of the oil box form a butt joint end and a plug end of the oil screen 11 respectively.

Further, the other two sides of the oil screen 11 are both folded inwards to form side-turning edges 115, and the side-turning edges 115 are preferably vertically connected with the main screen part 111, so as to simplify the processing, and make the side-turning edges 115 more easily fit with the side walls of the oil smoke inlet, so that the oil screen 11 can better cover the oil smoke inlet.

The greater the angle between the abutting cuff part 112 and the main web part 111, the more difficult the abutting end is to be inserted into the V-shaped groove 127, but the more effectively the oil screen 11 inserted into the V-shaped groove 127 is prevented from coming out of the V-shaped groove 127, and therefore the angle between the abutting cuff part 112 and the main web part 111 is preferably 120 ° to 150 °, and more preferably 135 ° to 150 °, so as to prevent the oil screen 11 after being attached from coming out of the V-shaped groove 127 while ensuring the smoothness of insertion or withdrawal of the abutting end of the oil screen 11 into the V-shaped groove 127. Most preferably, the abutting flange portion 112 makes an angle of 143 ° with the main panel portion 111. Further, the angle between the insertion flange portion 113 and the main panel portion 111 is greater than 60 ° and less than 90 °.

The side of the abutting flange part 112 away from the main panel part 111 and the side of the inserting flange part 113 away from the main panel part 111 are both folded inwards to form a reinforcing flange part 114, and the reinforcing flange part 114 is opposite to and spaced from the main panel part 111. The arrangement of the reinforced flanging part 114 can enhance the rigidity and the structural strength of the oil screen 11 at the inserting end and the abutting end, and avoid the problem of bending deformation of the abutting flanging part 112 or the inserting flanging part 113 caused by collision between the oil screen 11 and the groove wall of the inserting groove 133 or the groove wall of the V-shaped groove 127 in the process of dismounting the oil screen 11.

Further, in order to prevent the oil screen 11 from scratching an operator in the process of loading and unloading, the tail ends of the two side-turn edges 115 and the tail ends of the two reinforced side-turn edges 114 are both turned inwards to form edge-covering parts 116, and the edge-covering parts 116 are attached to the inner sides of the corresponding reinforced side-turn edges 114 and the corresponding side-turn edges 115, so that the edges of the oil screen 11 are prevented from being exposed, the edges of the oil screen 11 are prevented from scratching a user, and the safety of the user in the process of disassembling the oil screen 11 is improved.

In order to further improve the convenience of oil net 11 dismouting, be provided with on the main network board portion 111 and detain the hole 1111, detain the hole 1111 and set up at least two along the length direction interval of oil net 11, and detain hole 1111 and can supply user's finger to insert to make things convenient for the user to snatch oil net 11 through detaining hole 1111. In this embodiment, three fastening holes 1111 are provided at intervals along the length direction of the oil screen 11, and in other embodiments, only two fastening holes 1111 may be provided on the oil screen 11.

In this embodiment, the oil screen 11 is preferably integrally formed by a sheet metal structure, so that the processing is convenient.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model.
