[0037] like Figures 1 to 10As shown, this embodiment provides a magnetic fixing structure for fixing the baffle 100 on the smoke hood 200. The magnetic fixing structure includes a mounting seat 1 and a first magnetic member 2 disposed in the mounting seat 1. The mounting seat 1 is disposed on one of the baffle 100 and the smoke hood 200. The first magnetic member 2 can magnetically attract the other of the baffle 100 and the smoke hood 200. The first magnetic member 2 and the mounting seat 1 are spaced apart from each other toward the outer surface of the baffle 100 or the smoke hood 200. The baffle 100 can be made of carbon steel material, and the first magnetic member 2 can be made of a strong magnet. The strong magnet and the carbon steel material can generate a strong magnetic attraction between each other, thereby ensuring the reliability of the fixed installation of the baffle 100 and the smoke hood 200.

[0038] The baffle 100 and the smoke hood 200 are fixedly installed by a magnetic fixing structure. For example, a mounting base 1 is set on the smoke hood 200, and the baffle 100 is magnetically attracted by the first magnetic member 2, so that the baffle 100 can be quickly fixed, installed and disassembled on the smoke hood 200. The installation operation is simple and convenient, the installation cost is low, the installation accuracy requirements for the baffle 100 are low, the installation difficulty of the baffle 100 is reduced, time and labor are saved, and the problem of the baffle 100 being installed too loose or too tight can be effectively solved, thereby improving the user experience. Since the first magnetic member 2 is hidden in the mounting base 1, and the first magnetic member 2 is at a certain distance from the outer surface of the mounting base 1 facing the baffle 100, the first magnetic member 2 is avoided from being exposed outside the mounting base 1, the first magnetic member 2 is protected from being damaged, the service life of the first magnetic member 2 is extended, and the problem of damage to the first magnetic member 2 caused by long-term influence of magnetic attraction can be effectively alleviated. Of course, the mounting base 1 is arranged on the baffle 100, and the smoke collecting hood 200 is magnetically attracted by the first magnetic attraction member 2, which also has the above-mentioned beneficial effects.

[0039] In order to reduce the influence of the wall thickness of the mounting base 1 on the magnetic attraction force of the first magnetic component 2, the mounting base 1 is optionally provided with a magnetizing hole 11, and the magnetizing hole 11 is located between the first magnetic component 2 and the outer surface of the mounting base 1 facing the baffle 100 or the smoke hood 200. Under the premise of not affecting the structural strength of the mounting base 1, the magnetizing hole 11 appropriately reduces the local wall thickness of the mounting base 1, thereby weakening the influence of the wall thickness of the mounting base 1 on the magnetic attraction force of the first magnetic component 2, and enhancing the magnetic attraction effect of the first magnetic component 2 on the baffle 100. The magnetizing hole 11 can be circular or rectangular, which is not limited here. The first magnetic component 2 can be provided with one, two or more, which is not limited here. The magnetizing hole 11 can be a through hole or a blind hole. The through hole is convenient for achieving a stronger magnetizing effect, and the blind hole is conducive to ensuring the structural strength of the mounting base 1. The first magnetic attraction member 2 may be a circular magnet, which is coaxially arranged with the magnetization hole 11 , thereby maximally weakening the effect of the wall thickness of the mounting base 1 on the magnetic attraction force of the first magnetic attraction member 2 .

[0040] In some embodiments, the magnetic fixing structure further includes a limit seat 3, which is disposed on the baffle 100 or the smoke hood 200. The limit seat 3 can cooperate with the mounting seat 1 to limit the mounting seat 1, thereby avoiding the problem of the baffle 100 falling due to the inadequate cooperation between the baffle 100 and the smoke hood 200. The limit seat 3 can be made of carbon steel material, and the first magnetic attraction member 2 can be made of a strong magnet. The strong magnet and the carbon steel material can generate a strong magnetic attraction force, thereby ensuring the reliability of the cooperation between the mounting seat 1 and the limit seat 3, and further ensuring the installation reliability of the baffle 100.

[0041] Optionally, the limiting seat 3 is provided with a limiting groove 31, and the end of the mounting seat 1 can be inserted into the limiting groove 31. The limiting seat 3 can be provided with a boss structure, and the limiting groove 31 is opened on the boss structure, so as to avoid the modification and upgrading of the existing baffle, and there is no need to change the processing and manufacturing process of the existing baffle, saving the modification and upgrading cost. The limiting groove 31 can play an all-round limiting role on the end of the mounting seat 1, and prevent the baffle 100 from falling due to improper installation. The limiting groove 31 can be a circular groove or a square groove, which is not limited here. One end of the mounting seat 1 is thinner, and the other end is thicker. The thin end of the mounting seat 1 is inserted into the limiting groove 31, and the thick end of the mounting seat 1 is fixedly connected to the smoke hood 200 or the baffle 100.

[0042] In some embodiments, the magnetic fixing structure also includes a second magnetic member 4, which is disposed in the limit seat 3, and the second magnetic member 4 has opposite magnetism to the first magnetic member 2. The first magnetic member 2 and the second magnetic member 4 are both made of magnetic materials, and the two can be fixed by suction. For example, the first magnetic member 2 and the second magnetic member 4 can both be magnets, and the N pole of the first magnetic member 2 faces the S pole of the second magnetic member 4, or the S pole of the first magnetic member 2 faces the N pole of the second magnetic member 4. The first magnetic member 2 and the second magnetic member 4 can both have one, two, or more, which are not limited here.

[0043] Optionally, the limit seat 3 is bonded to the baffle 100 or the smoke hood 200. The bottom of the limit seat 3 is a flat structure, which is convenient for providing a larger bonding area. The limit seat 3 is fixedly connected to the baffle 100 or the smoke hood 200 by bonding, which can conveniently and quickly upgrade the existing baffle without changing the processing and manufacturing process of the existing baffle, saving the cost of upgrading.

[0044] In some embodiments, the smoke hood 200 is provided with a connecting plate 300, and the mounting base 1 is connected to the connecting plate 300 through a fastener. The connecting plate 300 is provided with a connecting hole 301, and the mounting base 1 is provided with a threaded hole 12. The fastener passes through the connecting hole 301 and is threadedly matched with the threaded hole 12. The fastener can be a screw, which is low in cost.

The connecting plate 300 is provided with a recessed structure, and the connecting hole 301 is provided at the bottom of the recessed structure, which is convenient for hiding the fastener and ensuring the beauty of the smoke hood 200. One end of the mounting base 1 is thinner and the other end is thicker. The first magnetic suction member 2 is embedded in the thin end position of the mounting base 1, and the threaded hole 12 is opened at the thick end position of the mounting base 1.

[0045] Optionally, the mounting base 1 is provided with a weight-reducing groove 13 and a mounting shaft 14, the mounting shaft 14 is located in the weight-reducing groove 13, and the threaded hole 12 is provided on the mounting shaft 14. The mounting shaft 14 is a hollow structure, and the threaded hole 12 is provided on the inner wall of the mounting shaft 14. The weight-reducing groove 13 can reduce the weight of the mounting base 1, and avoid applying excessive force to the smoke hood 200 or the baffle 100. The mounting shaft 14 is connected to the inner wall of the weight-reducing groove 13 through a reinforcing rib plate 15, so as to avoid the mounting shaft 14 being suspended in the air and causing insufficient connection strength.

[0046] In some embodiments, one of the baffle 100 and the smoke hood 200 is provided with a limiting protrusion 101, and the other of the baffle 100 and the smoke hood 200 is provided with a mounting bracket 201 that is engaged with the limiting protrusion 101. The mounting bracket 201 can be bonded to the lower side of the smoke collecting chamber of the smoke hood 200, and the limiting protrusion 101 of the baffle 100 is inserted into the limiting groove of the mounting bracket 201 to achieve preliminary fixation of the baffle 100 and the smoke hood 200, and then the baffle 100 is magnetically attracted by the magnetic fixing structure to achieve rapid fixing, installation and removal of the baffle 100 on the smoke hood 200.

[0047] The present embodiment also provides a range hood, comprising a baffle 100, a smoke hood 200 and the above-mentioned magnetic fixing structure, the number of magnetic fixing structures can be one, two or more, which is not limited here. The baffle 100 is fixedly installed on the smoke hood 200 by the magnetic fixing structure, so that the baffle 100 can be quickly fixed, installed and disassembled on the smoke hood 200, the installation operation is simple and convenient, the installation cost is low, the installation accuracy requirement of the baffle 100 is low, the installation difficulty of the baffle 100 is reduced, time and labor are saved, and the problem of the baffle 100 being installed too loose or too tight can be effectively solved, thereby improving the user experience.
