The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0035] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.
[0036] See Figures 1 to 9 This utility model embodiment provides a switch structure for a range hood, including a switch box 1, a box cover 2, and a switch assembly 3. The switch assembly 3 may include a control board and a control module, a display module, etc., connected to the control board. The control module may be at least one of a touch module, a mechanical module, or an intelligent module. The intelligent module includes a sensor control module and a voice control module. The sensor control module can perform operations such as power on / off and fan speed adjustment through gesture sensing, while the voice control module can perform operations such as power on / off and fan speed adjustment based on voice commands.
[0037] The switch box 1 has a receiving cavity and an opening communicating with the receiving cavity. The opening on the switch box 1 allows the switch assembly 3 to be assembled into the receiving cavity through the opening.
[0038] The cover 2 engages with the opening of the switch box 1 to close the opening. The cover 2 and the switch box 1 are connected to close the opening, and the receiving cavity forms a closed space.
[0039] The switch assembly 3 is located inside the receiving cavity and is snapped into the inner wall of the switch box 1.
[0040] In the range hood switch structure of this embodiment, the switch box 1 and the cover 2 can form a closed receiving cavity. The cover 2 snaps into the opening of the switch box 1, sealing the opening. The cover 2 is connected to the switch box 1 by snapping, making assembly simple, convenient, and quick. The switch assembly 3 is disposed inside the receiving cavity and snaps into the inner wall of the switch box 1. The switch assembly 3 is snapped into the receiving cavity, making assembly simple, convenient, and quick, and avoiding deformation of the switch assembly 3 caused by screw connections.
[0041] In some embodiments, see Figure 3 , Figure 6 and Figure 7The inner wall of the switch box 1 is provided with a first limiting structure 4 and a second limiting structure 5. The second limiting structure 5 is closer to the opening than the first limiting structure 4. There is a gap between the first limiting structure 4 and the second limiting structure 5 in the depth direction of the receiving cavity. The switch assembly 3 is embedded in the gap. The switch assembly 3 can be assembled into the switch box 1 through the opening. When the switch assembly 3 moves from the opening to the bottom, the switch assembly 3 and / or the switch box 1 undergo a certain elastic deformation, causing the switch assembly 3 to pass over the second limiting structure 5 and be blocked by the first limiting structure 4. After the switch assembly 3 passes over the second limiting structure 5, the interaction between the switch assembly 3 and the second limiting structure 5 disappears, the elastic deformation is restored, and the switch assembly 3 is stuck in the gap between the first limiting structure 4 and the second limiting structure 5.
[0042] In some embodiments, see Figure 6 and Figure 7 The second limiting structure 5 has a first guide surface 51 near the opening, and the switch assembly 3 is embedded in the gap along the first guide surface 51. During the movement of the switch assembly 3 from the opening to the bottom, the switch assembly 3 interacts with the first guide surface 51, and the first guide surface 51 guides the switch assembly 3, making it easy for the switch assembly 3 to pass over the first guide surface 51, which is beneficial for the assembly of the switch assembly 3.
[0043] In practice, the control board of the switch assembly 3 is embedded in the gap, thereby enabling the switch assembly 3 to snap into the switch box 1.
[0044] In an exemplary embodiment, a first limiting structure 4 and a second limiting structure 5 are respectively provided on the two opposing inner walls of the switch box 1, thereby forming gaps on the two opposing side walls to accommodate the switch assembly 3.
[0045] In a specific embodiment, the switch box 1 can be generally rectangular in shape. The switch box 1 may include a base plate, two side plates, and two end plates, which together form a receiving cavity with an opening on one side. The inner walls of the two side plates may be respectively provided with a first limiting structure 4 and a second limiting structure 5.
[0046] The two side panels can be bent into a stepped shape. The stepped side panels divide the switch box 1 into two parts with different widths, where the width of the top part near the opening is greater than the width of the bottom part away from the opening.
[0047] In some embodiments, see Figure 7 The first limiting structure 4 includes a support portion 41, and the side of the support portion 41 facing the opening has a support surface 411, forming a gap between the support surface 411 and the second limiting structure 5. The support portion 41 may be a stepped structure formed on the inner wall of the switch box 1, with the stepped surface facing the opening forming the support surface 411. The switch assembly 3 is embedded between the support surface 411 and the second limiting structure 5.
[0048] The support portion 41 may include a protrusion 74 protruding from the inner wall of the switch box 1. The side of the protrusion 74 facing the opening forms a support surface 411.
[0049] The support part 41 can be cylindrical, and the support part 41 extends upward from the bottom of the receiving cavity along the inner wall surface of the switch box 1.
[0050] The number of first limiting structures 4 and second limiting structures 5 on one side of the inner wall of the switch box 1 can each be multiple. The number of first limiting structures 4 and second limiting structures 5 on one side of the inner wall of the switch box 1 can be the same or different. In an exemplary embodiment, the number of first limiting structures 4 on one side of the inner wall of the switch box 1 can be more than the number of second limiting structures 5.
[0051] In some embodiments, see Figure 6 and Figure 7 The first limiting structure 4 includes a guide portion 42 extending from the support portion 41 toward the opening. The guide portion 42 has a second guide surface 421 on its side near the opening. The second guide surface 421 and the first guide surface 51 partially overlap in the depth direction of the receiving cavity. This partial overlap allows the first guide surface 51 and the second guide surface 421 to relay the guidance of the switch assembly 3, and the overlapping area jointly guides the switch assembly 3.
[0052] The guide portion 42 and the second limiting structure 5 are staggered, and the second guide surface 421 and the first guide surface 51 partially overlap in the depth direction of the receiving cavity. This allows the second guide surface 421 and the first guide surface 51 to simultaneously guide the switch assembly 3 when it is assembled into the switch box 1, facilitating its assembly. In an exemplary embodiment, as the switch assembly 3 moves from the opening to the bottom, the first guide surface 51 may initially guide it. When the switch assembly 3 moves to the overlapping section, the second guide surface 421 and the first guide surface 51 jointly guide it. After passing the first guide surface 51, the second guide surface 421 then guides the switch assembly 3.
[0053] Of course, during the movement of the switch assembly 3 from the opening to the bottom, it can also be that the first guide surface 51 first guides the switch assembly 3, and when the switch assembly 3 moves to the overlapping area, the first guide surface 51 still guides the switch assembly 3. After passing the first guide surface 51, the second guide surface 421 guides the switch assembly 3. The second guide surface 421 and the first guide surface 51 partially overlap in the depth direction of the receiving cavity, which allows for a smooth transition when the first guide surface 51 and the second guide surface 421 take turns guiding the switch assembly 3.
[0054] In some embodiments, see Figure 3 and Figure 6 The inner wall of the switch box 1 has a first slot 11, and the cover 2 has a first hook 21. The first hook 21 engages with the first slot 11 to engage the cover 2 with the switch box 1. During assembly, the cover 2 moves toward the opening, and the first hook 21 contacts the switch box 1 and undergoes elastic deformation. When the cover 2 continues to move until the first hook 21 is aligned with the first slot 11, the first hook 21 returns to its original shape and embeds into the first slot 11, thus engaging the cover 2 with the switch box 1.
[0055] The first slot 11 on the switch box 1 can be either a through hole or a blind hole. In a specific implementation, the first slot 11 on the switch box 1 can be a through hole, which can increase the sealing of the switch box 1 and reduce the impact of oil and other contaminants on the internal switch assembly 3.
[0056] In some embodiments, see Figure 6 and Figure 7 The first slot 11 and the second limiting structure 5 are arranged longitudinally, with the first slot 11 closer to the opening relative to the second limiting structure 5, and the longitudinal direction perpendicular to the bottom of the receiving cavity. During assembly, the second limiting structure 5 can limit the first hook 21, so that the first hook 21 is accurately embedded in the first slot 11.
[0057] In some embodiments, see Figure 6 and Figure 7 The first slot 11 is connected to the second limiting structure 5. The second limiting structure 5 can effectively limit the first hook 21, preventing the first hook 21 from crossing the first slot 11 during assembly.
[0058] In some embodiments, see Figure 1 and Figure 4 A foolproof structure 6 is provided between the cover 2 and the switch box 1. This foolproof structure 6 ensures correct assembly of the cover 2 and the switch box 1. The foolproof structure 6 may include a foolproof post and a foolproof groove, one of which is located on the cover 2, and the other on the switch box 1. When the cover 2 and the switch box 1 are correctly assembled, the foolproof post is located within the foolproof groove. If the cover 2 and the switch box 1 are incorrectly assembled, the foolproof post and the foolproof groove will misalign, and the cover 2 cannot be assembled into the switch box 1.
[0059] In some embodiments, see Figure 8 and Figure 9 The range hood switch structure also includes a switch bracket 7, and the switch box 1 is detachably connected to the unfolding bracket. In an exemplary embodiment, one side of the switch box 1 is snapped into the switch bracket 7, and the other side is connected to the switch bracket 7 by screws. Using a combination of snap-fit and screw connection to connect the switch box 1 and the switch bracket 7 can improve the assembly speed and make the connection between the switch box 1 and the switch bracket 7 more secure.
[0060] In some embodiments, see Figure 8 The switch bracket 7 has a window 75, through which the switch box 1 passes, and the periphery of the switch box 1 is detachably connected to the switch bracket 7. The window 75 facilitates the design and layout of the connection structure between the switch box 1 and the switch bracket 7.
[0061] In some embodiments, the first side of the window 75 has a first limiting plate 71, the first limiting plate 71 has a second slot 73, and one side of the switch box 1 has a card block 12 corresponding to the second slot 73.
[0062] In some embodiments, the second side of the window 75 has a protrusion 74 with a screw hole, and the other side of the switch box 1 has a mounting ear 13 corresponding to the protrusion 74 with a through hole for the screw to pass through. The first side and the second side are opposite to each other. The protrusion 74 on the switch bracket 7 provides sufficient connection space for the screw, preventing the screw from passing through the switch bracket 7 and protruding from the other side of the switch bracket 7. During assembly, the locking block 12 on the switch box 1 can be inserted into the second locking slot 73 first, and then the mounting ear 13 can be fixed to the protrusion 74 with screws.
[0063] In an exemplary embodiment, the protrusion 74 may be formed by stamping. A groove is formed on the opposite side of the switch bracket 7 opposite to the protrusion 74.
[0064] In an exemplary embodiment, a nut may be welded onto the switch bracket 7 to form a protrusion 74.
[0065] In some embodiments, see Figure 8 The window 75 has second limiting plates 72 on each of its two adjacent sides. The two second limiting plates 72 and the first limiting plate 71 form a limiting space to accommodate the switch box 1. By setting limiting plates on the three adjacent sides of the window 75, the switch box 1 can be effectively limited. A protrusion 74 is provided on the side where no limiting plate is provided.
