[0040] Reference Figures 1 to 9 In one embodiment of the utility model, a switch 300 fixing structure is provided, and the switch 300 fixing structure includes a bottom plate 100, a bracket 200 and a switch 300. The bracket 200 is disposed on the bottom plate 100, and the switch 300 is detachably mounted on the bracket 200. The bottom plate 100 has a blocking portion 110 arranged circumferentially around the switch 300, and the blocking portion 110 has an abutting surface 111 capable of sealingly abutting against the glass panel 400.

[0041] In the above structure, by setting the bottom plate 100, the bracket 200 is set on the bottom plate 100, and the switch 300 is detachably installed on the bracket 200, wherein the bottom plate 100 has a blocking portion 110 arranged around the circumference of the switch 300, and the blocking portion 110 has an abutting surface 111 that can be sealed and connected with the glass panel 400. During installation, the abutting surface 111 of the blocking portion 110 is sealed and abutted with the inner side surface of the glass panel 400. Therefore, during the use of the range hood, the blocking portion 110 can prevent oil smoke and oil stains from flowing along the inner side surface of the glass panel 400 and penetrating between the switch 300 and the glass panel 400, thereby protecting the switch 300 and reducing the impact of oil smoke and oil stains generated by cooking on the switch 300. In addition, when the switch 300 needs to be replaced and repaired, it is only necessary to remove the switch 300 from the bracket 200 without replacing the entire glass panel 400. The operation is simple, making the replacement and repair of the switch 300 more convenient.

[0042] Reference Figures 1 to 6 In some embodiments, the outer periphery of the blocking portion 110 is provided with a first peripheral edge 120 extending toward a side away from the abutting surface 111 .

[0043] In the above structure, by providing the first surrounding edge 120 on the outer periphery of the blocking portion 110, the oil smoke and oil stains on the inner side of the glass panel 400 can be better blocked, and the oil smoke and oil stains can be further prevented from flowing along the inner side of the glass panel 400 and penetrating between the switch 300 and the glass panel 400, thereby better protecting the switch 300 and reducing the impact of the oil smoke and oil stains generated by cooking on the switch 300.

[0044] It is understandable that the outer periphery of the blocking portion 110 is provided with a first peripheral edge 120 extending toward the side away from the abutting surface 111. Specifically, the first peripheral edge 120 can be formed by bending the outer periphery of the blocking portion 110 toward the side away from the abutting surface 111, thereby facilitating the processing of the first peripheral edge 120, making the production and processing of the bottom plate 100 more convenient, and improving the production efficiency of the bottom plate 100. Of course, in addition to this, the first peripheral edge 120 can also be connected to the outer periphery of the blocking portion 110 by welding or other connection methods, which is not specifically limited by the present invention.

[0045] Reference Figures 1 to 6 In some embodiments, the inner periphery of the blocking portion 110 is provided with a second peripheral edge 130 extending toward a side away from the abutting surface 111 .

[0047] It is understandable that the inner periphery of the blocking portion 110 is provided with a second peripheral edge 130 extending toward the side away from the abutting surface 111. Specifically, the second peripheral edge 130 can be formed by bending the inner periphery of the blocking portion 110 toward the side away from the abutting surface 111, thereby facilitating the processing of the second peripheral edge 130, making the production and processing of the bottom plate 100 more convenient and improving the production efficiency of the bottom plate 100. Of course, in addition to this, the second peripheral edge 130 can also be connected to the inner periphery of the blocking portion 110 by welding or other connection methods, which is not specifically limited by the present invention.

[0048] Reference Figures 1 to 6 In some embodiments, the abutting surface 111 of the blocking portion 110 can be bonded to the glass panel 400 , and the blocking portion 110 is provided with a plurality of through holes 112 .

[0049] In the above structure, the abutting surface 111 of the blocking portion 110 can be bonded to the glass panel 400 by gluing, and the glue can extend into the through hole 112, thereby increasing the tightness of the connection between the bottom plate 100 and the glass panel 400, making the installation of the bottom plate 100 more secure, and further increasing the connection sealing between the abutting surface 111 of the blocking portion 110 and the glass panel 400.

[0050] It is understandable that, referring to Figures 1 to 6All the through holes 112 are arranged at intervals along the circumference of the blocking portion 110, thereby increasing the connection stability between the bottom plate 100 and the glass panel 400. It is understandable that the utility model does not specifically limit the number of through holes 112, and the number of through holes 112 can be one, two, three, four or more, which is not specifically limited in the utility model.

[0051] It can be understood that the blocking portion 110 has an abutment surface 111 that can be sealed against the glass panel 400. In order to achieve the sealed abutment between the abutment surface 111 of the blocking portion 110 and the glass panel 400, in addition to bonding the abutment surface 111 of the blocking portion 110 to the glass panel 400, the abutment surface 111 of the blocking portion 110 can also be sealed against the glass panel 400 by negative pressure adsorption. The specific abutment method between the abutment surface 111 of the blocking portion 110 and the glass panel 400 is not specifically limited by the present invention.

[0052] Reference Figures 1 to 9 In some embodiments, there are two brackets 200 , and the two brackets 200 are correspondingly disposed on two opposite sides of the bottom plate 100 , and the switch 300 is detachably mounted on the two brackets 200 .

[0053] In the above structure, by providing two brackets 200 , and correspondingly arranging the two brackets 200 on two opposite sides of the bottom plate 100 , the installation of the switch 300 can be made more balanced and stable.

[0054] It is understandable that the number of the above-mentioned brackets 200 is two, which is only for Figures 1 to 9 As an exemplary illustration, the number of the brackets 200 may be not only two, but also one, three, four or more, which is not specifically limited in the present invention.

[0055] Reference Figures 1 to 8 In some embodiments, the bracket 200 includes a first connecting plate 210 and a mounting plate 220 . The first connecting plate 210 is mounted on the base plate 100 . The mounting plate 220 is formed by bending the edge of the first connecting plate 210 . The switch 300 is detachably mounted on the mounting plate 220 .

[0056] In the above structure, the bracket 200 is divided into a mounting plate 220 and a first connecting plate 210. The mounting plate 220 is formed by bending the edge of the first connecting plate 210, so that the bracket 200 can be installed on the base plate 100 through the first connecting plate 210, and a detachable connection with the switch 300 is achieved through the mounting plate 220. In addition, this structure can also increase the structural strength of the bracket 200, so that the bracket 200 can better support the switch 300 and reduce the occurrence of adverse phenomena such as stress deformation of the bracket 200 during use.

[0057] Reference Figures 1 to 8 In some embodiments, the base plate 100 is provided with second connecting plates 140 corresponding to the two brackets 200 one by one, the first connecting plate 210 is installed on the corresponding second connecting plate 140, the first connecting plate 210 is provided with a positioning groove 211, and the second connecting plate 140 is provided with a positioning boss 141 that can be embedded in the positioning groove 211.

[0058] In the above structure, by opening a positioning groove 211 on the first connecting plate 210 and providing a positioning boss 141 matched with the positioning groove 211 on the second connecting plate 140, the positioning boss 141 and the positioning groove 211 can cooperate to position the first connecting plate 210 and the second connecting plate 140, and then can position the bracket 200 and the base plate 100, so that the installation of the bracket 200 is more convenient, thereby improving the production and processing efficiency of the switch 300 fixing structure.

[0059] It is understandable that the first connecting plate 210 is provided with a positioning groove 211, and the second connecting plate 140 is provided with a positioning boss 141 capable of being embedded in the positioning groove 211. Figures 1 to 8 An exemplary description is given. In addition, the positioning groove 211 can also be opened on the second connecting plate 140, and the positioning boss 141 can be set on the second connecting plate 140. The present invention does not make specific limitations on this. It only requires that one of the first connecting plate 210 and the corresponding second connecting plate 140 has a positioning groove 211, and the other has a positioning boss 141 that can be embedded in the positioning groove 211.

[0060] Reference Figures 1 to 8 In some embodiments, the first connecting plate 210 has a first bending portion 230 and a second bending portion 240. The first bending portion 230 is formed by bending the edge of the first connecting plate 210 inward, and the second bending portion 240 is formed by bending the free end of the first bending portion 230 toward a side close to the base plate 100. The mounting plate 220 is formed by bending the free end of the second bending portion 240 toward a side away from the first bending portion 230.

[0061] In the above structure, a first bending portion 230 and a second bending portion 240 are arranged between the first connecting plate 210 and the mounting plate 220. The first bending portion 230 is formed by bending the first connecting plate 210, the second bending portion 240 is formed by bending the first bending portion 230, and the mounting plate 220 is formed by bending the second bending portion 240. This can greatly increase the structural strength of the bracket 200, making the structure of the bracket 200 more stable, thereby enabling the bracket 200 to better support the switch 300, thereby reducing the occurrence of adverse phenomena such as stress deformation of the bracket 200 during use.

[0062] It can be understood that the first bending portion 230 is formed by bending the edge of the first connecting plate 210 inwardly, specifically, the first bending portion 230 is formed by bending the edge of the first connecting plate 210 toward the direction close to the switch 300. The second bending portion 240 is formed by bending the free end of the first bending portion 230 toward the side close to the bottom plate 100, wherein the free end of the first bending portion 230 specifically refers to the side edge of the first bending portion 230 away from the first connecting plate 210. The mounting plate 220 is formed by bending the free end of the second bending portion 240 toward the side away from the first bending portion 230, wherein the free end of the second bending portion 240 specifically refers to the side edge of the second bending portion 240 away from the first bending portion 230.

[0063] It is understandable that, referring to Figures 1 to 8 The first bending portion 230 is formed by bending the edge of the first connecting plate 210 inwardly, the second bending portion 240 is formed by bending the free end of the first bending portion 230 toward the side close to the bottom plate 100, and the mounting plate 220 is formed by bending the free end of the second bending portion 240 toward the side away from the first bending portion 230, wherein the angle between the first bending portion 230 and the first connecting plate 210 is 90 degrees, and the angle between the second bending portion 240 and the first bending portion 230 is 90 degrees, so that the first bending portion 230, the second bending portion 240 and the first connecting plate 210 are mutually enclosed to form an inverted "U" shape, and in addition, the angle between the mounting plate 220 and the second bending portion 240 is also 90 degrees. This structure can not only increase the structural strength of the bracket 200, but also make the processing of the first bending portion 230, the second bending portion 240 and the mounting plate 220 more convenient.

[0064] In some embodiments, the first connection plate 210 is welded to the second connection plate 140 , and the switch 300 is detachably connected to the two mounting plates 220 via screw fasteners.

[0065] In the above structure, by welding the first connecting plate 210 and the second connecting plate 140, the bracket 200 can be installed more firmly and stably, so that the bracket 200 can better support the installation of the switch 300. The switch 300 is detachably connected to the two mounting plates 220 by screw fasteners, which makes the removal and installation of the switch 300 simpler and more convenient. The installation and removal of the switch 300 can be achieved by only screwing the screws, which is convenient for the replacement and maintenance of the switch 300.

[0066] It is understandable that, referring to Figures 1 to 8A first mounting hole 221 is provided on the mounting plate 220, and a second mounting hole 310 corresponding to the first mounting hole 221 is provided on the switch 300. Therefore, during installation, the screw fasteners can be installed in the corresponding first mounting hole 221 and second mounting hole 310, which is simple and convenient to operate.
