DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0027] Embodiment one, please refer to Figures 1 to 7 The oil fume separating and filtering device of the oil fume machine comprises an oil fume machine shell 1, an oil fume inlet 1011 is formed in the middle of an oil fume inlet side 101 of the oil fume machine shell 1, a gas guide ring 2 is fixed in the middle of the oil fume inlet side 101 and is in communication with the oil fume inlet 1011, the gas guide ring 2 is composed of an oil collecting part 201 which is arranged in a hollow truncated cone shape close to the oil fume inlet side 101 and a sleeve part 202 which is arranged in a ring shape away from the oil fume inlet side 101, a filter screen 3 is fixed to the middle of the inner wall of the sleeve part 202;

[0028] An oil filter opening 4 is formed in the lower end of the sleeve part 202 on both sides of the filter screen 3, a sealing plate 5 is slidingly installed on the outer wall of the lower end of the sleeve part 202, the sealing plate 5 is connected to the oil fume inlet side 101 through an elastic connecting piece, and the elastic connecting piece can close one oil filter opening 4 close to the oil fume inlet side 101 by the sealing plate 5;

[0029] A flip cover 6 is rotatably installed on the upper end of the oil fume machine shell 1 close to the oil fume inlet side 101 through a damping shaft, no matter how many degrees the flip cover 6 is turned to, the flip cover 6 can keep the opening angle through the damping shaft, the flip cover 6 can surround the gas guide ring 2 when the flip cover 6 is closed to the oil fume inlet side 101, and an electric heating wire 11 is fixed to the position of the inner side 601 close to the oil fume inlet side 101 and opposite to the gas guide ring 2;

[0030] When the oil fume machine is used, the flip cover 6 is turned over, the flip cover 6 is closed to the oil fume inlet side 101, the gas guide ring 2 and the filter screen 3 are surrounded, the electric heating wire 11 is opposite to the filter screen 3 in this state, the filter screen 3 is heated through the electric heating wire 11, so that the oil attached to the filter screen 3 is heated and softened, the flow performance is increased, the oil slides down along the filter screen 3 and drops to the oil filter opening 4, the effect of automatic cleaning of the filter screen 3 is realized, the filter screen 3 always has good permeability, manual disassembly and washing are not needed, and manpower is saved;

[0031] And because of the filter oil port 4 near the smoke side 101 of the oil leakage problem exists when the hood works, that is, the oil fume will pass through the filter oil port 4 over the filter screen 3 directly into the hood;

[0032] The elastic connecting piece includes two slide rods 7 symmetrically fixed on the sealing plate 5 near the smoke side 101, both of which are connected with the smoke side 101 through the sliding hole, and the outer side of the slide rod 7 is provided with a spring 8, one end of which is fixed with the outer wall of the smoke side 101, and the other end is fixed with the outer wall of the sealing plate 5;

[0033] In the normal state of not compression and stretching, the sealing plate 5 keeps closed to the state of the filter oil port 4 near the smoke side 101 under the action of the spring 8, so that when the hood works, the oil fume will not pass through the filter screen 3 directly into the hood from the filter oil port 4;

[0034] Both ends of the sealing plate 5 are formed with downwardly bent extension 501, and the trigger assembly includes push bar 9 symmetrically fixed on the inner side 601 of the cover 6 corresponding to the position of the extension 501, which is matched with the extension 501;

[0035] And when the filter screen 3 needs to be cleaned, the grease on the inner side of the filter screen 3, that is, the side near the smoke side 101, needs to be dropped through the filter oil port 4 on this side, so the extension 501 and the push bar 9 are arranged, and in the process of closing the cover 6, the end of the push bar 9 is in contact with the extension 501, and in the process of completely closing, the push bar 9 pushes the extension 501, so that the sealing plate 5 slides to the side near the smoke side 101 under the compression of the spring 8, and when it is completely closed, the sealing plate 5 opens the filter oil port 4 completely.

[0036] Embodiment two, please refer to Figure 8 This embodiment provides further technical solutions based on embodiment one, the middle part of the lower end of the smoke side 101 is provided with an oil collecting box 10, and both filter oil ports 4 are located above the oil collecting box 10, and the oil collecting box 10 is located between the two extensions 501;

[0037] The grease cleaned from the filter oil port 4 drops into the oil collecting box 10 through the filter oil port 4, and the oil collecting box 10 can be fixed on the outer wall of the smoke side 101 by a magnet when in use, and the oil fume hood shell 1 is made of stainless steel material which can be attracted by the magnet, so that the oil collecting box 10 can be conveniently disassembled and assembled;

[0038] And it needs to be emphasized that the two push bars 9 are located on both sides of the oil collecting box 10, so that in the opening and closing process of the cover 6, the push bar 9 will not conflict with the oil collecting box 10, and at the same time, the lower edge of the inner side 601 of the cover 6 will not hinder the oil collecting box 10 in the process of turning over.

[0039] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
