[0062] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0063] This embodiment provides a switch box structure, which can be applied to an integrated stove to achieve quick disassembly and assembly, enhance the oil fume protection capability, improve the pressure resistance, and at the same time improve the safety of the switch box assembly and the range hood, and improve the user experience.

[0064] like Figures 1 to 15As shown, the switch box mechanism includes a switch bracket 100 and a switch box 200, wherein the switch bracket 100 has a accommodating channel and a limiting groove 101 connected to the accommodating channel; the accommodating channel extends in the left-right direction, and the limiting groove 101 extends in the up-down direction; the switch box 200 includes a box body 210 extending in the left-right direction and a limiting protrusion 220 provided on the box body 210, the limiting protrusion 220 extends in the up-down direction, the switch box 200 is penetrated in the accommodating channel in the left-right direction, and the limiting protrusion 220 is inserted in the limiting groove 101.

[0065] The switch box mechanism is provided with a receiving channel on the switch bracket 100 so that the switch box 200 can be inserted into the receiving channel, avoiding the need to provide a hole structure around the switch box 200, which is beneficial to reducing the volume of the switch box 200, and is helpful to miniaturizing the range hood and reducing the occupied space of the range hood; at the same time, the rear channel wall of the receiving channel also plays a certain supporting role for the switch box 200. When the user presses the switch box 200 to operate, the pressure resistance of the switch box 200 is effectively improved due to the support of the rear channel wall of the receiving channel, thereby reducing the deformation, improving the user's experience, and ensuring the function of the switch box 200; since the limiting protrusion 220 is provided on the box body 210 of the switch box 200, the box body 210 is limited in the left and right directions and the front and rear directions. Combined with the structure of the receiving channel, the switch bracket 100 can limit the freedom of the switch box 200 in all directions, thereby ensuring the stability of the switch box 200 and improving the assembly efficiency of the switch box 200.

[0066] To improve the convenience of production and assembly of the switch bracket 100, in this embodiment, the switch bracket 100 includes a bracket base 110 and a bracket cover 120. The bracket cover 120 covers and is fixed to the bracket base 110 and surrounds a receiving channel.

[0067] The box body 210 is in the shape of a rectangular parallelepiped, and the bracket base 110 includes a bracket fixing plate 111, and the upper and lower ends of the bracket fixing plate 111 are folded backward to form a first bracket side plate 112 and a second bracket side plate 113, respectively, and the first bracket side plate 112 and the second bracket side plate 113 are opposite to each other up and down; the bracket cover plate 120 includes a plate-shaped, the upper side of the bracket cover plate 120 is connected to the first bracket side plate 112, the lower side of the bracket cover plate 120 is connected to the second bracket side plate 113, and the bracket cover plate 120 and the bracket fixing plate 111 are opposite to each other front and back. The angle between the first bracket side plate 112 and the bracket fixing plate 111 is a right angle; the angle between the second bracket side plate 113 and the bracket fixing plate 111 is a right angle; the first bracket side plate 112 and the second bracket side plate 113 are parallel, and the bracket cover plate 120 is parallel to the bracket fixing plate 111. Since the box body 210 is in the shape of a rectangular parallelepiped, the relative arrangement of the first bracket side plate 112 and the second bracket side plate 113 and the relative arrangement of the bracket cover plate 120 and the bracket fixing plate 111 in the bracket base 110 and the bracket cover plate 120 provided in this embodiment realizes the limitation of the freedom of the box body 210 in the front-to-back direction and the up-and-down direction; at the same time, the first bracket side plate 112 and the bracket fixing plate 111 are at right angles, and the second bracket side plate is at right angles to the bracket fixing plate 111, so that the entire switch bracket 100 has a square shape and is easy to produce.

[0068] In order to improve the connection convenience and connection stability between the bracket base 110 and the bracket cover plate 120, the first bracket side plate 112 is provided with a bracket plug hole 1121, and the second bracket side plate 113 is provided with a bracket plug groove 1132; the upper side of the bracket cover plate 120 is provided with a first cover plug part 124, and the lower side of the bracket cover plate 120 is provided with a second cover plug part 125, the first cover plug part 124 is plugged into the bracket plug hole 1121, and the second cover plug part 125 is plugged into the bracket plug groove 1132. By setting the bracket plug hole 1121 and the bracket plug groove 1132, the first cover plug part 124 can be directly plugged into the bracket plug hole 1121, and the second cover plug part 125 can be plugged into the bracket plug groove 1132 by swinging, thereby improving the connection convenience of the bracket cover plate 120 and the bracket base 110, and improving the assembly efficiency of the bracket cover plate 120 and the bracket base 110.

[0069] In order to improve the connection stability between the bracket base 110 and the bracket cover plate 120, the bracket plug-in hole 1121 penetrates the first bracket side plate 112 in the up and down direction; the first cover plug-in portion 124 is plugged into the bracket plug-in hole 1121 and can slide in the left and right direction; the bracket plug-in groove 1132 includes a connected bracket transverse groove 11321 and a bracket longitudinal groove 11322, the length direction of the bracket transverse groove 11321 is the left and right direction, the length direction of the bracket longitudinal groove 11322 is the front and back direction, and it penetrates the second bracket side plate 113 backward, and the second cover plug-in portion 125 can be plugged into the bracket longitudinal groove 11322 forward and can slide to the left into the bracket transverse groove 11321. By setting the long strip-shaped bracket plug-in hole 1121 and the bracket transverse groove 11321, the first cover plug-in portion 124 is plugged into the bracket plug-in hole 1121, which can complete the front and rear direction limitation, and the second cover plug-in portion 125 is plugged into the bracket transverse groove 11321, which can also complete the front and rear direction limitation, so that the bracket cover 120 is limited in the front and rear direction relative to the bracket base 110; at the same time, when the first cover plug-in portion 124 and the left side wall of the bracket plug-in hole 1121 are abutted and / or the second cover plug-in portion 125 and the left side wall of the bracket transverse groove 11321 are abutted, the relative position of the bracket cover 120 and the bracket base 110 can be accurately defined, thereby improving the convenience of installation.

[0070] In order to limit the bracket cover 120 in the upper and lower directions, the bracket cover 120 includes a cover body 121, and the upper and lower sides of the cover body 121 are folded backward to form a first cover flange 122 and a second cover flange 123 respectively. The first cover flange 122 and the second cover flange 123 are arranged opposite to each other up and down, and are clamped between the first bracket side plate 112 and the second bracket side plate 113. By setting the first cover flange 122 and the second cover flange 123, the first bracket side plate 112 is pressurized on the upper side of the first cover flange 122, and the second bracket side plate 113 is supported on the lower side of the second cover flange 123; thereby, after the bracket cover 120 is fixed to the bracket base 110, the bracket cover 120 is limited in the up and down directions; at the same time, the first cover flange 122 is formed by folding the upper end of the cover body 121 backward, and the second cover flange 123 is formed by folding the lower end of the cover body 121 backward, which can simplify the processing of the first cover flange 122 and the second cover flange 123, and also simplify the overall structure of the bracket cover 120, thereby reducing the processing difficulty of the bracket cover 120.

[0071] like Figure 5As shown, the support cover 120 is provided with a toggle portion 126, and the toggle portion 126 is toggled along the direction A to drive the support cover 120 to slide in the left and right directions. The provision of the toggle portion 126 makes the sliding of the support cover 120 more convenient, and improves the convenience and efficiency of disassembly and assembly. Specifically, the right side of the cover body 121 is folded backward to form the toggle portion 126. This provision improves the connection strength between the toggle portion 126 and the cover body 121.

[0072] In order to reduce the processing difficulty of the first cover plug-in portion 124, one end of the first cover flange 122 away from the cover body 121 is folded upward to form the first cover plug-in portion 124. The method of forming the first cover plug-in portion 124 after the first cover flange 122 is folded also improves the connection strength between the first cover plug-in portion 124 and the first cover flange 122; at the same time, the first cover plug-in portion 124 is as far away from the cover body 121 as possible, thereby avoiding interference with the space enclosed by the cover body 121 and the bracket base 110, which is conducive to ensuring the installation space of the switch box 200 and improving the installation efficiency and installation accuracy of the switch box 200.

[0073] The second cover plug-in portion 125 includes a second cover connection portion 1251 and a second cover stop portion 1252. The upper end of the second cover connection portion 1251 is connected to the cover body 121. The lower end of the second cover connection portion 1251 is folded back to form the second cover stop portion 1252. The second cover connection portion 1251 is plugged into the bracket plug-in slot 1132, and the second cover stop portion 1252 is located at the lower side of the second bracket side plate 113. The second cover stop portion 1252 is located at the lower side of the second bracket side plate 113, so that the second cover connection portion 1251 cannot be pulled out upward from the bracket plug-in slot 1132, so that the second cover plug-in portion 125 and the bracket plug-in slot 1132 are plugged stably, thereby ensuring the reliability of the connection between the bracket base 110 and the bracket cover plate 120.

[0074] The second bracket side plate 113 has a cover mounting hole 1131, the second cover flange 123 has a cover fixing hole 1231, and the fixing screw 130 passes through the cover mounting hole 1131 and is screwed into the cover fixing hole 1231. In this arrangement, the bracket base 110 and the bracket cover plate 120 can be fixed by only one fixing screw 130, and combined with the plug-in fit at various locations, the limitation between the two in various degrees of freedom is achieved, the assembly process is simplified, and thus the assembly efficiency is improved.

[0075] In order to improve the connection reliability between the bracket base 110 and the bracket cover 120, in this embodiment, two bracket insertion holes 1121 and two first cover insertion parts 124 are respectively provided, and the two bracket insertion holes 1121 are arranged at intervals in the left-right direction; the two first cover insertion parts 124 are respectively inserted into the corresponding bracket insertion holes 1121. The provision of the two first cover insertion parts 124 enables the bracket cover 120 to be connected to the bracket base 110 at two locations, effectively improving the connection stability between the bracket base 110 and the bracket cover 120, avoiding the first cover insertion part 124 from being too long in the left-right direction, saving materials, and facilitating processing, which is conducive to improving the convenience of assembly.

[0076] The bracket fixing plate 111 has a first plate surface and a second plate surface that are arranged opposite to each other, the first bracket side plate 112 and the second bracket side plate 113 are both arranged on the first plate surface, and the second plate surface is used to be attached to the panel 400. This arrangement allows the first bracket side plate 112 and the second bracket side plate 113 to be folded in the same direction, which is more convenient to produce and has better structure and stability.

[0077] In the left-right direction, the length of the switch box 200 is greater than the length of the switch bracket 100. The switch box 200 passes through the accommodating channel, and the two ends of the switch and are located in the accommodating channel. This arrangement makes the overall length of the switch bracket 100 smaller, reducing the quality and cost. It should be noted that for the button-type switch box 200, the bracket cover 120 needs to cover the position where the button is located to avoid deformation of the switch box 200 due to force when pressed.

[0078] The present embodiment also provides a fume hood that can be used in a range hood, which can improve the assembly efficiency of the fume hood, increase the service life of the fume hood, and improve the user experience.

[0079] The smoke hood includes a housing 300, a panel 400 and the switch box 200 structure in the above embodiment. The panel 400 is fixed to the housing 300, the switch bracket 100 is fixed to the panel 400, the panel 400 has an operating portion, and the button of the switch box 200 is opposite to the operating portion.

[0080] The housing 300 is provided with a snap-fitting groove 310, and the smoke hood further includes a snap-fitting bracket 500, which has a fixing portion 510 and a snap-fitting portion, the fixing portion 510 is fixed to the panel 400, and the snap-fitting portion is snap-fitted into the snap-fitting groove 310. This arrangement enables the panel 400 and the housing 300 to be fixed by snap-fitting, simplifies the connection method, and improves assembly efficiency.

[0081] The clamping portion includes a first clamping component 520, and the first clamping component 520 includes a first clamping connection portion 521 and a first clamping limit portion 522. The upper end of the fixed portion 510 is folded backward to form the first clamping connection portion 521. The first clamping connection portion 521 extends to the left away from one side of the clamping bracket 500 and forms a first clamping limit portion 522. The shell 300 at the left side wall of the clamping groove 310 is clamped between the first clamping limit portion 522 and the fixed portion 510. In this arrangement, the panel 400 is brought close to the housing 300 so that the first clamping limiter 522 passes through the clamping slot 310 from front to back. At this time, the fixing portion 510 is attached to the front of the housing 300. Then the panel 400 is moved to the left and the first clamping limiter 522 is moved to the rear side of the left side wall of the clamping slot 310. This completes the limitation of the panel 400 and the housing 300 in the front-to-back direction. The operation is simple and the clamping efficiency of the panel 400 and the housing 300 is improved. In this embodiment, the panel 400 is moved to the left, that is, referring to Fig. 9 In the embodiment, the panel 400 is moved along the direction B, thereby driving the first clamping limit portion 522 to move.

[0082] The clamping portion includes a second clamping component 530, and the second clamping component 530 includes a second clamping connection portion 531 and a second clamping limit portion 532. The lower end of the fixed portion 510 is folded backward to form the second clamping connection portion 531. The second clamping connection portion 531 extends to the left along a side away from the clamping bracket 500 and is formed with a second clamping limit portion 532. The shell 300 at the left side wall of the clamping groove 310 is clamped between the second clamping limit portion 532 and the fixed portion 510. This arrangement brings the panel 400 close to the shell 300 so that the second snap-in limiting portion 532 passes through the snap-in slot 310 from front to back. At this time, the fixing portion 510 is attached to the front of the shell 300. The panel 400 is then moved to the left and the second snap-in limiting portion 532 is moved to the rear side of the left side wall of the snap-in slot 310. This completes the limitation of the panel 400 and the shell 300 in the front and rear directions. The operation is simple and the snap-in efficiency of the panel 400 and the shell 300 is improved.

[0083] In order to improve the convenience of plugging, in this embodiment, in the front-to-back direction, the distance between the first clamping limit portion 522 and the fixing portion 510 gradually increases in the left direction, and the maximum distance between the first clamping limit portion 522 and the fixing portion 510 is greater than the thickness of the housing 300, and the minimum distance between the first clamping limit portion 522 and the fixing portion 510 is less than the thickness of the housing 300. This arrangement enables the distance between the first clamping limit portion 522 and the fixing portion 510 to adapt to the housing 300 structure of different thicknesses, and ensures that the first clamping limit portion 522 and the fixing portion 510 are both in contact with the housing 300 to clamp the housing 300, thereby improving the connection firmness between the panel 400 and the housing 300, and avoiding the first clamping limit portion 522 and the fixing portion 510 not fitting with the housing 300, resulting in shaking between the panel 400 and the housing 300, thereby generating noise or even wear.

[0084] A guide portion 525 is provided at the left end of the first clamping limit portion 522, and the guide portion 525 is inclined to the right from front to back. The guide portion 525 is in a planar shape, and can smoothly guide the housing 300 between the first clamping limit portion 522 and the fixing portion 510; at the same time, the provision of the guide portion 525 reduces the material used for the first clamping limit portion 522, thereby reducing the cost and quality. It should be noted that the guide portion 525 is also provided at the second clamping limit portion 532.

[0085] In order to improve the connection stability between the panel 400 and the shell 300 in the up and down directions, in this embodiment, an elastic portion 523 is connected between the fixing portion 510 and the first snap-fit ​​connection portion 521 and the second snap-fit ​​connection portion 531; the lower bottom surface of the snap-fit ​​groove 310 includes a first bottom surface 3101, a second bottom surface 3102 and an inclined surface 3103 connected between the first bottom surface 3101 and the second bottom surface 3102, and the distance between the upper top surface of the snap-fit ​​groove 310 and the first bottom surface 3101 is greater than the distance between the upper top surface of the snap-fit ​​groove 310 and the second bottom surface 3102, and the second snap-fit ​​connection portion 531 can slide from the first bottom surface 3101 along the inclined surface 3103 to the second bottom surface 3102. The arrangement of the first bottom surface 3101 and the second bottom surface 3102 makes the snap-in groove 310 present a step shape. When the panel 400 moves to the left, the first snap-in connection portion 521 can smoothly slide to the second bottom surface 3102 through the inclined surface 3103. Due to the different heights between the two bottom surfaces, that is, the first bottom surface 3101 is lower than the second bottom surface 3102, after the first snap-in connection portion 521 moves to the second bottom surface 3102, the height increases, thereby driving the snap-in bracket 500 to rise. Since the second snap-in connection portion 531 abuts against the upper side wall of the snap-in groove 310, the snap-in bracket 500 is clamped between the second bottom surface 3102 and the upper side wall of the snap-in groove 310.

[0086] An elastic part 523 and a supporting part 524 are connected between the fixing part 510 and the first clamping connection part 521. The upper end of the fixing part 510 is folded upward and backward to form an inclined elastic part 523. The upper end of the elastic part 523 is folded upward to form a supporting part 524 of a vertical structure. The upper end of the supporting part 524 is folded backward to form the first clamping connection part 521. Under the action of the elastic part 523, the first clamping connection part 521 and the second clamping connection part 531 always have a movement tendency to move away from each other, so that the first clamping connection part 521 and the second clamping connection part 531 are kept in a tensioned state in the clamping groove 310, thereby maintaining a stable connection between the clamping bracket 500 and the housing 300 in the up and down directions.

[0087] In order to reduce the mass of the fixing part 510, in this embodiment, the fixing part 510 is provided with a through weight-reducing hole 511, and the axis of the weight-reducing hole 511 extends in the front-to-back direction. By providing the weight-reducing hole 511, the material used for the entire fixing part 510 can be reduced, thereby reducing the mass of the fixing part 510; at the same time, when the clamping bracket 500 is bonded to the panel 400, the weight-reducing hole 511 can accommodate excess glue to prevent the glue from escaping to the periphery of the fixing part 510, thereby ensuring the cleanliness of the periphery of the fixing part 510, avoiding the impact on other electronic devices, and avoiding the interference between the protruding structure generated by the solidification of the periphery glue and other components.

[0088] There are at least two clamping slots 310, wherein two clamping slots 310 are arranged at intervals in the vertical direction, and the first clamping limit portion 522 and the second clamping limit portion 532 are respectively clamped to the corresponding clamping slots 310; the lower bottom surface of the lower clamping slot 310 is a step structure. This arrangement makes the size of each clamping slot 310 smaller, and can make the upper side wall of the upper clamping slot 310 and the lower side wall of the lower clamping slot 310 have a larger distance, which meets the structure of the panel 400 with a larger size in the vertical direction; at the same time, it helps to improve the strength of the shell 300.
