[0029] As Figures 1-3 shown, in a preferred embodiment of the present utility model, a magnet structure of an embodiment of the present utility model includes a rubber sleeve 1 and a magnet 2.
[0030] The rubber sleeve 1 is provided with a cavity 14 having a volume equal to or slightly larger than the volume of the magnet 2, and the magnet 2 is disposed in the cavity 14.
[0031] Since the magnetic permeability of the rubber material is very low, the magnetic force of the magnet 2 can pass through the rubber sleeve 1 and adsorb and connect with the oil mesh, the smoke collecting hood or other metal products.
[0032] Since the magnet 2 is embedded in the rubber sleeve 1, the rubber sleeve 1 separates the magnet 2 from the oil mesh, the smoke collecting hood or other metal products, so that there is a rubber sleeve for buffering between the oil mesh, the magnet and the smoke collecting hood, achieving the purpose of noise reduction and vibration reduction, and avoiding the noise generated by the collision during the instant of adsorption and the operation of the range hood.
[0033] In a preferred embodiment of the present utility model, the rubber sleeve 1 includes a bottom wall 11, a first annular side wall 12 fixedly connected to the bottom wall 11, and an annular top wall 13 fixedly connected to the first annular side wall 12.
[0034] The cavity 14 is formed by the common enclosure of the bottom wall 11, the first annular side wall 12 and the annular top wall 13. The bottom wall 11, the first annular side wall 12 and the annular top wall 13 are integrally formed. The inner wall of the oil screen 4 abuts against the annular top wall 13 and is adsorbed on the magnet structure to fix the oil screen 4.

[0036] In a preferred embodiment of the present utility model, a second annular side wall 112 is provided on the bottom wall 11 and extends towards the inside of the cavity 14 around the second through hole 111. The second annular side wall 112 is inserted into the first through hole 21, and the second annular side wall 112 is configured to separate the hole wall of the first through hole 21 from the bolt, so as to achieve the purpose of noise reduction and vibration reduction.
[0037] As Figure 3 shown, in a preferred embodiment of the present utility model, one side of the magnet 2 abuts against the bottom wall 11, and there is a spacing a between the other side of the magnet 2 and the annular top wall 13. The spacing a is 1-5 mm, so as to further improve the buffering effect. The diameter of the magnet 2 is 20-50 mm.
[0038] In a preferred embodiment of the present utility model, the cross sections of the rubber sleeve 1 and the magnet 2 are any one of a circle, an ellipse and a polygon.

The wall thickness of the rubber sleeve 1 is 1-5 mm.
[0040] In a preferred embodiment of the present utility model, the rubber sleeve 1 is a soft rubber, and the soft rubber has the effects of good elasticity and good toughness. When the magnet 2 is installed from the central hole of the annular top wall 13, the magnet 2 expands the central hole of the annular top wall 13. After the magnet 2 is placed into the cavity 14, the annular top wall 13 returns to its initial state.
[0041] When the magnet structure of the present utility model is applied to a range hood product, nitrile rubber is preferably used. Nitrile rubber has excellent vibration reduction and noise reduction effects, and nitrile rubber also has excellent properties of oil resistance, wear resistance and heat resistance.
[0042] As Figures 4-5As shown in the figure, the present utility model further provides an oil fume extractor, which includes a smoke collecting hood 3, an oil mesh 4 and at least one of the above-mentioned magnet structures. The magnet structure is installed on the smoke collecting hood 3 or the oil mesh 4, and the oil mesh 4 is adsorbed and connected to the smoke collecting hood 3 through the magnet structure.
[0043] Since the oil mesh of the oil fume extractor provided by the present utility model is connected to the smoke collecting hood by using the above-mentioned magnet structure, there is a rubber sleeve between the oil mesh, the magnet and the smoke collecting hood for buffering, achieving the purpose of noise reduction and vibration reduction, and avoiding the noise generated by collision during vibration at the moment of adsorption and during the operation of the smoke machine.
[0044] In a preferred embodiment of the present utility model, it further includes two mounting bolts.

A clamping hole is provided in the upper part of the smoke collecting hood 3, and a third through hole is provided in the front side wall below the air inlet of the smoke collecting hood 3.
[0045] When fixing, the threaded end of the bolt passes through the first through hole 21 of the magnet 2, the second through hole 111 of the bottom wall 11 and the third through hole and then is connected to the nut. In this way, the nut and the bolt head jointly clamp and fix the magnet 2 and the rubber sleeve 1 on the front side wall below the air inlet of the smoke collecting hood 3.
[0046] As Figure 5 shown, Figure 5 is the rear view (inner side surface of the oil mesh 4) of the oil mesh 4. The upper end of the oil mesh 4 is provided with a plug foot 41 corresponding to the clamping hole. The plug foot 41 is inserted into the clamping hole of the smoke collecting hood 3, and then the oil mesh 4 is rotated towards the magnet structure until the inner wall of the oil mesh 4 abuts against the annular top wall 13 and is adsorbed on the magnet structure, realizing the fixation of the oil mesh 4.
