[0060] The utility model will be described in further detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the utility model, and not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0061] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0062] In the utility model, unless otherwise expressly provided and limited, the first feature is "on" or "under" the second feature, which can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "on the surface of" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0063] In the description of the embodiment, the terms "upper", "lower", "right", "left", "horizontal", "vertical", "orientation" or "position relationship" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0064] The embodiment provides an oil fume treatment device, which can be an extractor hood, an integrated stove and the like. Hereinafter, the oil fume treatment device is taken as an extractor hood for example. It should be noted that the orientation description of front, rear, left, right, up and down in the following text is relative to the user when the oil fume treatment device is normally working.

[0065] As shown in Figure 1 , the oil fume treatment device can be a flat-embedded extractor hood. In other embodiments, the oil fume treatment device can also be a traditional side-suction extractor hood and the like, which is not limited herein. Specifically, the oil fume treatment device comprises a device main body 200 and a control mechanism 100, wherein the device main body 200 comprises a rack and a fan, the fan is installed on the rack, and a smoke collecting cavity 201 is formed in the rack. The control mechanism 100 is connected with the device main body 200, and the control mechanism 100 comprises a control assembly, which is used for user operation to control the oil fume treatment device to start and stop or switch the working state. When the fan is working, a negative pressure area is formed in and around the smoke collecting cavity 201, so that the oil fume generated in the cooking process is sucked into the smoke collecting cavity 201 and finally discharged to the outdoor. The operation mode of the control assembly includes touch operation and empty-handed gesture operation, some control assemblies have a touch area for user touch operation, wherein the touch area can include touch keys, mechanical keys and the like. Some control assemblies have an empty-handed gesture operation area, and the control assembly with the empty-handed operation function is a prior art, and its specific structure and working principle will not be described herein.

[0066] In some embodiments, as Figure 1 andFigure 2 As shown, the control mechanism 100 is movably connected with the device body 200 to enable opening or closing of the smoke collecting cavity 201. When the fan needs to work, the control mechanism 100 opens the smoke collecting cavity 201 to facilitate the oil fume entering the smoke collecting cavity 201. When the fan stops working, the control mechanism 100 blocks the smoke collecting cavity 201, which not only ensures the appearance of the oil fume treatment device, but also prevents the backflow of external oil fume. In the embodiment, the opening of the smoke collecting cavity 201 is located at the front side of the rack and is obliquely arranged. The control mechanism 100 is arranged at the opening of the smoke collecting cavity 201, and the upper end is connected with the rack through the hinge 300. As shown, Figure 2 When the control mechanism 100 is flipped to the front side of the device body 200 around the hinge 300 at the upper end, the opening of the smoke collecting cavity 201 is realized, and at this time, the control mechanism 100 can also play a role in gathering the smoke, thereby improving the effect of the oil fume treatment device in adsorbing the oil fume. When the control mechanism 100 is flipped to the back side of the device body 200 around the hinge 300 at the upper end, the smoke collecting cavity 201 can be closed. Alternatively, the flipping action of the control mechanism 100 can be realized through the existing driving structure such as an electric push rod, and the details of the specific driving structure are not described herein.

[0067] In summary, in the embodiment, the control mechanism 100 not only accommodates the control components for controlling the oil fume treatment device, but also can be flipped relative to the device body 200, thereby playing a role in gathering the smoke and improving the effect of the oil fume treatment device in adsorbing the oil fume. It can be understood that in other embodiments, the control mechanism 100 can also be arranged to be fixedly connected with the rack, and at this time, the control mechanism 100 does not have the effect of gathering the smoke.

[0068] As shown, Figures 3-5 The control mechanism 100 includes a front panel 10 and a back panel 20. The front surface of the front panel 10 is arranged towards the outside of the smoke collecting cavity 201 and can serve as a partial outer surface of the oil fume treatment device. In the embodiment, the front panel 10 is a glass panel, which can ensure that the user can control the control components 010 through the front panel 10, and has good appearance and is easy to clean. The front panel 10 is substantially rectangular, and the left-right direction of the front panel 10 is the length direction thereof. The back panel 20 is mounted on the back surface (i.e. the side facing the smoke collecting cavity 201) of the front panel 10, and the back panel 20 is provided with a mounting hole 21 for mounting the control components 010. After the control components 010 are mounted into the mounting hole 21, the control components 010 are in contact with the front panel 10. The user can perform touch control operation on the touch control area of the control components 010 by touching the front surface of the front panel 10. For the control components 010 having the function of gesture control in the air, the user can also perform gesture control in the air through the front panel 10. In some embodiments, the control components are provided with LED light prompts at the touch control area and / or the gesture control area in the air, thereby facilitating the user to more intuitively know the positions of the corresponding areas. In some embodiments, an identifier can also be arranged on the front panel 10 at the positions corresponding to the touch control area and / or the gesture control area in the air.

[0069] As shown in Figure 3 , the back plate 20 is processed by sheet metal, which not only can provide support for the panel 10 and ensure the structural strength of the whole operating mechanism 100, but also can be used for installing the hinge 300 to facilitate connection with the rack. In the embodiment, the back plate 20 includes a main body part 22 and a protruding part 23, the main body part 22 is arranged in close contact with the panel 10, thereby uniformly supporting the panel 10. Alternatively, the main body part 22 and the panel 10 can be connected by bonding. The protruding part 23 is recessed from the middle region of the main body part 22 to the side away from the panel 10, and the mounting hole 21 is opened on the protruding part 23. The setting of the protruding part 23 forms a certain space between the back plate 20 and the panel 10, thereby accommodating the operating assembly 010 with a certain thickness.

[0070] As shown in Figure 3 , the operating mechanism 100 further includes a cover plate 60, which is connected with the back plate 20 and seals one end of the mounting hole 21 away from the panel 10. The cover plate 60 can protect the operating assembly 010 in the mounting hole 21, preventing oil smoke from depositing on the operating assembly 010 to affect the sensitivity of the operating assembly 010. In the embodiment, the sidewall of the mounting hole 21 has a rib part 24, which is convexly arranged inward along the radial direction of the mounting hole 21, and the cover plate 60 is lapped on the side of the rib part 24 away from the panel 10 and connected with the rib part 24. The rib part 24 not only provides a mounting position for the cover plate 60, but also is used for surrounding to form an installation area matching the outer shape of the operating assembly (see the description below). Alternatively, the surface of the rib part 24 away from the panel 10 is lower than the surface of the protruding part 23 away from the panel 10, thereby forming a sunken groove, and the cover plate 60 is installed in the sunken groove. The sunken groove can play a positioning role for the cover plate 60, not only improving the convenience of installation, but also improving the sealing performance of the connection position, thereby better preventing oil smoke from depositing on the operating assembly 010.

[0071] As shown in Figure 3 , the rib part 24 of the embodiment is provided with a slot 241 and a first hole 242, and the cover plate 60 is provided with a plug 61 and a second hole 62, the plug 61 is inserted into the slot 241, the first hole 242 and the second hole 62 are oppositely arranged, the fastener is inserted through the second hole 62 and connected with the first hole 242, thereby realizing the fixation of the cover plate 60, which is simple in structure and convenient to operate. In the embodiment, the fastener can be a bolt, and the first hole 242 is a threaded hole. It can be understood that the number of the slot 241 and the slot 241, the number of the first hole 242 and the second hole 62 can be flexibly set according to the needs, which are not limited here. In other embodiments, the cover plate 60 and the rib part 24 can also be fixed by welding, bonding and other ways, which are not limited here.

[0072] In the development of oil fume treatment device, a series of products are usually planned according to the demand function, channel positioning and other factors, and different control modes are used to launch multiple models to meet market demand. The control assembly includes a support and a circuit board, and the circuit board is installed on the support shell, as shown in Figure 5 , based on different control modes, the control assembly contains different types and models of circuit boards, so the size of the support shell (i.e. the entire control assembly 010) will also change accordingly. If a size-matched back plate 20 and cover plate 60 are designed for each type of control assembly 010, it will result in high design and manufacturing costs of the entire series of oil fume treatment devices.

[0073] To this end, as shown in Figure 4 , the mounting hole 21 is arranged in at least two different mounting areas, so that the corresponding type of control assembly 010 can be installed in different mounting areas according to different use requirements, thereby adapting to different models of oil fume treatment equipment. In this embodiment, the projection of the mounting area on the panel 10 overlaps at least one of the projections of the other mounting areas on the panel 10, so that the back plate 20 is more compact based on being compatible with different models of control assembly 010.

[0074] In some embodiments, as shown in Figure 4 , different mounting areas can be arranged staggered along the length direction (i.e. left-right direction) of the panel 10. That is, the projection of one of the mounting areas on the panel 10 at least overlaps the projection of another mounting area on the panel 10 in the left-right direction. In some embodiments (not shown), the two mounting areas are arranged intersecting each other, that is, the projection of one of the mounting areas on the panel 10 intersects the projection of the other mounting area on the panel 10.

[0075] In order to ensure that the mounting area formed by the mounting hole 21 can be compatible with various different models of control assembly 010, it is necessary to first confirm the boundary range of the length (left-right direction) and width of the mounting hole 21. Specifically, as shown in Figures 5-7 , n different control assemblies 010 are known, and the width size B and length size L of the mounting hole 21 are designed as follows: as shown in Figure 5 , for the width size, the widths of each control assembly 010 are B1, B2, B3…Bn respectively, and the width B of the mounting hole 21 is B≥B(B1, B2, B3…Bn)max, it should be noted that the width size B referred to here and below refers to the size of the approximate outline position of the control assembly 010, and does not include the size of the local small protrusions or grooves. As shown in Figure 6 and Figure 7As shown, for the length dimension: the centerline of panel 10 in the first direction is defined as the reference centerline L0. In this embodiment, the first direction is the left-right direction, which is the length direction of panel 10. To ensure the aesthetics of the control mechanism 100, after the control component 010 is installed on the back plate 20, the centerline of the touch area of ​​the control component 010 in the first direction (i.e., the left-right direction) coincides with the reference centerline L0. Therefore, the length design of the mounting hole 21 is as follows: first, obtain the centerline of the touch area of ​​each control component 010 in the left-right direction; then, obtain the dimensions of each model of control component 010 to the left of the corresponding centerline, namely LL1, LL2, LL3…LLn, and take LLmax = LL(LL1, LL2, LL3…LLn)max. Also, obtain the dimensions of each model of control component 010 to the right of the aforementioned centerline, namely LR1, LR2, LR3…LRn, and take LRmax = LR(LR1, LR2, LR3…LRn)max. Then, the length L of the mounting hole 21 is ≥ (LLmax + LRmax).

[0076] like Figures 8-10 As shown, this embodiment provides three different models of control components 010, specifically, Figure 8 This is a schematic diagram of the first type of control component 010. The control component 010 is a touch-sensitive color filter switch and includes a first support housing 41, a first circuit board 42, and a color filter. The first circuit board 42 is disposed inside the first support housing 41. The color filter is electrically connected to the first circuit board 42 and is attached to the surface of the first support housing 41. When the control component 010 is installed, the color filter is attached to the panel 10. The touch area of ​​the first type of control component 010 is rectangular, with a width of B1 and a length of L1. Figure 9 This is a schematic diagram of the second type of control component 010. This control component 010 is a touch switch, and its internal circuit board is a second circuit board 52. The second circuit board 52 has four buttons 020, and the outer rectangle of each button 020 constitutes the touch area of ​​the control component 010. When installing the control component 010, the buttons 020 are directly or indirectly connected to the panel 10. The width of the second type of control component 010 is B2, and its length is L2. Figure 10 This is a schematic diagram of the third type of control component 010. This control component 010 is another type of touch switch, and its internal circuit board is a third circuit board 53. The third circuit board 53 has five buttons 020, and the outer rectangle of each button 020 forms the touch area of ​​the control component 010. When installing the control component 010, the buttons 020 are directly or indirectly connected to the panel 20. The width of the third type of control component 010 is B3, and its length is L3.

[0077] In this embodiment, B1 < B2 = B3, L1 < L2 = L3, and the external dimensions of the second type of control component 010 are exactly the same as those of the third type of control component 010, only their internal circuit boards are different. Based on this, in this embodiment, the smaller first type of control component 010 is defined as the first control component 40, which is a color filter touch switch. The second and third types of control components 010, which have the same external dimensions and are larger than the first control component 40, are both defined as second control components 50, which are touch switches. In this embodiment, the second control component 50 generally refers to control components 010 with the same external dimensions but potentially different internal circuit board models.

[0078] like Figure 4 As shown, a first mounting area 210 and at least one second mounting area 220 are formed within the mounting hole 21. A first control component 40 is mounted in the first mounting area 210, and a second control component 50 is mounted in any one of the second mounting areas 220. In this embodiment, the first mounting area 210 and the second mounting area 220 are arranged along the length direction of the panel 10 and overlap.

[0079] Since the second control component 50 includes two models of control components 010 with different touch area distributions, to ensure that the center lines of the touch areas of both models of control components in the left-right direction coincide with the reference center line of the panel 10 in the left-right direction, this embodiment provides two second mounting areas 220. These two second mounting areas 220 are staggered in the left-right direction. Each second mounting area 220 is used to install one model of the second control component 50, thereby ensuring that the center lines of the control areas on both models of the second control components 50 in the left-right direction coincide with the center line of the panel 10 in the left-right direction, thus ensuring the aesthetics of various models of fume treatment devices. Of course, when the product series includes three or more models of the second control components 50, the number of second mounting areas 220 can be increased accordingly, and their positions can be flexibly adjusted to ensure that the center lines of the control areas of various models of control components 010 in the left-right direction coincide with the center line of the panel 10 in the left-right direction.

[0080] Because the first control component 40 is relatively small, in order to ensure that it can be confined in the first mounting area 210 and will not interfere with the installation of the second control component 50 in the second mounting area 220, such as Figure 11 and Figure 12As shown, the control mechanism 100, including the first control component 40, also includes an adapter 30. The first control component 40 is mounted on the adapter 30, and the adapter 30 is limited to the first mounting area 210. The adapter 30 can expand the external dimensions of the first control component 40 to facilitate its mating with the mounting hole 21, ensuring that the first control component 40 can be accurately positioned within the first mounting area 210.

[0081] Optionally, the mounting hole 21 has a limiting structure, and the first control component 40 cooperates with the limiting structure to be accurately positioned within the mounting hole 21. The second control component 50 cooperates with the limiting structure to be accurately positioned within the mounting hole 21.

[0082] like Figure 4 , Figures 11-14 As shown, in some embodiments, the limiting structure includes an adapter 30 and a limiting feature formed on the sidewall of the mounting hole 21. The limiting feature defines a portion of the first mounting area 210. The first control component 40 is installed in the adapter 30. The adapter 30 cooperates with the limiting feature to stably install the first control component 40 in the first mounting area 210.

[0083] In some embodiments, the limiting structure includes a limiting feature formed on the sidewall of the mounting hole 21, the limiting feature defining a portion of the second mounting area 220, and the second control component 50 cooperating with the limiting feature to stably mount the second control component 50 within the second mounting area 220.

[0084] In some embodiments, the limiting structure includes a limiting feature formed on the sidewall of the mounting hole 21, the limiting feature defining a portion of the first mounting region 210 and a portion of the second mounting region 220. An adapter 30, to which the first control component 40 is fixed, can engage with the limiting feature and be confined within the first mounting region 210. A second control component 50 can directly engage with the limiting feature and be confined within the second mounting region 220.

[0085] In the above embodiments, the adapter 30 and the second operation control component are respectively limited and installed by the limiting feature constructed directly on the side wall of the mounting hole 21, without the need to add additional mating parts or fasteners. The structure is simple, the cost is low, and the assembly is convenient and efficient.

[0086] In this embodiment, the limiting feature includes several limiting notches, such as Figure 11 and Figure 12As shown, the adapter 30 is provided with a first limiting protrusion 31, which engages with a portion of the limiting notch. The second control component 50 is provided with a second limiting protrusion 511, which engages with a portion of the limiting notch. By setting the limiting feature as a limiting notch, it is ensured that the structure defining the first mounting area 210 will not interfere with the installation of the second control component 50, and the structure defining the second mounting area 220 will not interfere with the installation of the first control component 40. In other embodiments, the limiting feature can also be constructed as several limiting protrusions. In this case, it is necessary to provide a clearance opening on the second control component 50 to avoid the limiting protrusions defining the first mounting area 210, and a clearance opening on the second control component 50 to avoid the limiting protrusions defining the second mounting area 220.

[0087] like Figure 4 , Figures 12-14 As shown, the limiting feature includes a first limiting feature 211 and at least one second limiting feature 212. The first limiting feature 211 defines at least a portion of the first mounting area 210. The first limiting feature 211 cooperates with the adapter 30 to limit the first control component 40 to the first mounting area 210. The second limiting feature 212 defines at least a portion of the second mounting area 220. The second limiting feature 212 can cooperate with the second control component 50 to limit the second control component 50 within the corresponding second mounting area 220. For schemes with two or more second mounting areas 220, each second mounting area 220 is respectively provided with a second limiting feature 212, which is used to limit the second control component 50 within the second mounting area 220. By selecting to mate the second control component 50 with different second limiting features 212, the position of the second control component 50 relative to the panel 10 can be selected, thereby ensuring that the center line of the touch area of ​​the second control component 50 in the left-right direction coincides with the center line of the panel 10 in the left-right direction after installation.

[0088] Optionally, in this embodiment, the first limiting feature 211 and the second limiting feature 212 can both be directly disposed on the rib portion 24, or can be formed by two adjacent rib portions 24 surrounding each other.

[0089] In this embodiment, as Figure 11 and 12 As shown, the first limiting protrusion 31 of the adapter 30 is disposed at one end in its length direction, and includes two protrusions distributed at both ends of its width. The mounting hole 21 has an upper sidewall, a lower sidewall, a left sidewall and a right sidewall, and the first limiting feature 211 is a limiting notch and includes two notches respectively disposed on the upper sidewall and the lower sidewall, and the two protrusions are correspondingly inserted into the two notches.

[0090] likeFigure 13 and Figure 14 As shown, the second limiting feature 212 is a limiting notch and is provided in two sets. The two sets of second limiting features 212 are defined as second limiting feature a2121 and second limiting feature b2122, arranged left and right respectively. The second control component 50 is provided with two sets of second limiting protrusions 511, defined as second limiting protrusion a5111 and second limiting protrusion b5112, arranged left and right respectively. For example... Figure 14 As shown, when the second limiting protrusion a5111 of a second control component 50 (i.e., the third type of control component 010 described above) engages with the second limiting feature a2121, the second control component 50 is confined within one of the second mounting areas 220, and the center line of its touch area in the left-right direction coincides with the center line of the panel 10 in the left-right direction. Figure 13 As shown, when the second limiting protrusion b5112 of another second control component 50 (i.e., the second type of control component 010 described above) engages with the second limiting feature b2122, the second control component 50 is confined within another second mounting area 220, and the center line of the touch area of ​​the second control component 50 in the left-right direction coincides with the center line of the panel 10 in the left-right direction. In this embodiment, combined with Figure 4 As shown, the second limiting feature a2121 is formed by the protruding rib 24 provided on the left side wall of the mounting hole 21 and the protruding ribs 24 provided on the upper and lower side walls of the mounting hole 21 respectively. The second limiting feature b2122 is formed by the protruding rib 24 provided on the right side wall of the mounting hole 21 and the protruding ribs 24 provided on the upper and lower side walls of the mounting hole 21 respectively.

[0091] like Figure 13 As shown, the first limiting feature 211, in addition to defining a portion of the first mounting area 210, can also define one of the second mounting areas 220 and cooperate with the second control component 50. This arrangement fully utilizes the existing first limiting feature 211 to limit the second control component 50, ensuring the accuracy of the second control component 50's position and the stability of its installation. In this embodiment, the first limiting feature 211 is positioned between two second limiting features 212. When the second limiting protrusion b5112 of the second control component 50 engages with the second limiting feature b2122, the second limiting protrusion a5111 of the second control component 50 also engages with the first limiting feature 211. In other words, the first limiting feature 211 and the second limiting feature b2122 jointly limit the second control component 50, thereby improving the accuracy of the second control component 50's installation position and the stability of its installation.

[0092] likeFigure 14 As shown, the limiting feature also includes a third limiting feature 213. In this embodiment, the third limiting feature 213 is a limiting groove. The third limiting feature 213 is disposed between the first limiting feature 211 and the second limiting feature b2122. When the second limiting protrusion a5111 of the second control component 50 is engaged with the second limiting feature a2121, the second limiting protrusion b5112 of the second control component 50 is engaged with the third limiting feature 213. That is, the second limiting feature a2121 and the third limiting feature 213 together limit the second control component 50, thereby improving the accuracy of the installation position and the firmness of the installation of the second control component 50.

[0093] like Figure 12 and Figure 15 As shown, a first gap 214 exists between the sidewall of the mounting hole 21 within the first mounting area 210 and the sidewall of the adapter 30. A first limiting protrusion 215 is provided within the first gap 214. The first limiting protrusion 215 connects to one of the sidewalls of the mounting hole 21 and the adapter 30, and abuts against the other. This arrangement creates a point fit between the adapter 30 and the sidewall of the mounting hole 21, ensuring precise positioning of the adapter 30 while reducing the installation difficulty of the adapter 30, thereby improving the assembly efficiency of the control mechanism 100. In this embodiment, the first limiting protrusion 215 is located on the sidewall of the mounting hole 21 within the first mounting area 210.

[0094] Similarly, the mounting hole 21 has a second gap between its sidewall in the second mounting area 220 and the sidewall of the second control component 50. A second limiting protrusion is provided within this second gap. The second limiting protrusion is fixedly connected to one of the sidewalls of the mounting hole 21 and the second control component 50, and abuts against the other. This arrangement creates a point fit between the second control component 50 and the mounting hole 21, ensuring precise positioning of the second control component 50 while reducing the installation difficulty of the second control component 50, thereby improving the assembly efficiency of the control mechanism 100. In this embodiment, the second limiting protrusion is located on the sidewall of the mounting hole 21 in the second mounting area 220.

[0095] In this embodiment, both the first limiting protrusion 215 and the second limiting protrusion are provided on the protruding rib portion 24. It should be noted that since the first mounting area 210 and the second mounting area 220 have an overlapping area, a portion of the sidewall of the mounting hole 21 is located in both the first mounting area 210 and the second mounting area 220. Therefore, a portion of the limiting protrusion on the sidewall of the mounting hole 21 serves as both the first limiting protrusion 215 and the second limiting protrusion.

[0096] like Figures 16-19As shown, a limiting groove 32 is provided on the adapter 30, and the first control component 40 is installed in the limiting groove 32. This arrangement allows the adapter 30 to expand the external dimensions of the first control component 40 and facilitates easy assembly and disassembly with the first control component 40.

[0097] like Figure 16 As shown, a mating boss 33 is provided on the side wall of the limiting groove 32. The mating boss 33 abuts against the side wall of the first control component 40 to limit the first control component 40. By mating the mating boss 33 with the side wall of the first control component 40, a point fit is formed between the first control component 40 and the limiting groove 32. This not only reduces the mating area between the adapter 30 and the first control component 40, reducing processing costs, but also makes it easier to assemble and disassemble the adapter 30 and the first control component 40. In this embodiment, the limiting groove 32 is approximately rectangular, and mating bosses 33 are provided on all three side walls of the limiting groove 32. In other embodiments, the distribution of the mating bosses 33 on the side walls of the limiting groove 32 can be flexibly adjusted, and no specific limitation is made here.

[0098] like Figure 16 As shown, at least part of the mating boss 33 has a chamfer 35 at its edge away from the bottom of the limiting groove 32. When the first control component 40 is installed into the limiting groove 32, the chamfer 35 acts as a guide, greatly improving the ease of installation of the first control component 40. In this embodiment, the mating boss 33, which is positioned opposite the sidewall without the mating boss 33, has a chamfer 35. Optionally, the chamfer 35 can be a sloped surface or an arc-shaped surface; no specific limitation is made here.

[0099] like Figures 16-18 As shown, of the side wall of the first control component 40 and at least one mating boss 33, one is provided with a latching protrusion 34, and the other is provided with a latching groove 411. The latching protrusion 34 is inserted into the latching groove 411. Through the cooperation of the latching protrusion 34 and the latching groove 411, the firmness of the cooperation between the adapter 30 and the first control component 40 can be further improved, thereby preventing the position of the first control component 40 from shifting during the use of the range hood and affecting the user's accurate operation. In this embodiment, the latching protrusion 34 is provided on the mating boss 33, and the latching groove 411 is provided on the first control component 40. The first control component 40 includes a first support shell 41, a first circuit board 42, and a color filter. The first circuit board 42 is installed inside the first support shell 41, and the latching groove 411 is formed on the first support shell 41. The color filter is electrically connected to the first circuit board 42, and is attached to the surface of the first support shell 41 and is abutted against the panel 10.

[0100] like Figure 20 and Figure 21As shown, the second control assembly 50 includes a second support housing 51, and a second limiting protrusion a5111 and a second limiting protrusion b5112 are both disposed on the second support housing 51. The second support housing 51 has at least two mounting positions, each for mounting a different type of circuit board. By mounting different types of circuit boards into the second support housing 51, different types of second control assemblies 50 are formed.

[0101] like Figure 20 and Figure 21 As shown, in this embodiment, a first mounting position 510 and a second mounting position 520 are provided inside the second support shell 51. The second control component 50 includes a second circuit board 52 or a third circuit board 53. The second circuit board 52 is mounted at the first mounting position 510, thereby forming one type of second control component 50. The second circuit board 52 is mounted at the second mounting position 520, thereby forming a second type of second control component 50. In this embodiment, the projection of the first mounting position 510 on the panel 10 overlaps with the projection of the second mounting position 520 on the panel 10, thereby making the second support shell 51 more compact while being compatible with both the second circuit board 52 and the third circuit board 53.

[0102] Specifically, the second support shell 51 is provided with connecting features for mounting the second circuit board 52 or the third circuit board 53. In some embodiments, the connecting feature is a snap-fit, which can engage with the second circuit board 52 or the third circuit board 53. In some embodiments, the connecting feature is a threaded hole, through which a fastener passes and is threadedly connected. Optionally, the connecting features shared by the second circuit board 52 and the third circuit board 53 can be used, thereby reducing the number of connecting features required on the second support shell 51, and thus reducing the manufacturing difficulty and cost of the second support shell 51. Figure 20 and Figure 21 As shown, taking a threaded hole as an example, the second circuit board 52 is provided with a second through hole 521, and the third circuit board 53 is provided with a third through hole 531. At least a portion of the second through hole 521, at the position where the second circuit board 52 is mounted on the second support shell 51, coincides with the position of the third through hole 531 after the third circuit board 53 is mounted on the second support shell 51. Therefore, this portion of the second through hole 521 and the third through hole 531 can share the same threaded hole for connection.

[0103] like Figure 20As shown, the second support shell 51 includes a bottom shell 5110 and a cover 5120. The bottom shell 5110 and the cover 5120 are interlocked and enclosed to form an installation space. The second circuit board 52 or the third circuit board 53 is installed in the installation space. The second support shell 51 can provide a relatively tight cover protection for the second circuit board 52 or the third circuit board 53, thereby preventing oil fumes from accumulating on the second circuit board 52 or the third circuit board 53.

[0104] like Figure 20 As shown, the second support shell 51 has a clearance hole on the side facing the panel 10. The clearance hole is configured to avoid the button 020 on the circuit board, ensuring that the button 020 can contact the panel 10 so that the button 020 can be triggered when the user touches the corresponding position of the panel 10.

[0105] In some embodiments, the clearance hole includes a first clearance hole 5121 and a second clearance hole 5122. The first clearance hole 5121 can accommodate buttons 020 on at least two different types of circuit boards, while the second clearance hole 5122 can accommodate buttons 020 on one type of circuit board. The first clearance hole 5121 allows for compatibility with buttons 020 on different types of circuit boards, reducing the processing cost of the second support shell 51. The second clearance hole 5122 can accommodate buttons 020 that are unique to and distributed on some types of circuit boards, preventing the clearance hole from being too large and weakening the strength of the second support shell 51. In this embodiment, the first clearance hole 5121 can accommodate at least some buttons 020 on the second circuit board 52 and at least some buttons 020 on the third circuit board 53, while the second clearance hole 5122 can accommodate some buttons 020 on the second circuit board 52 or a portion of the buttons 020 on the third circuit board 53. In other words, the second clearance hole 5122 is a clearance hole shared by both types of circuit boards, and the second clearance hole 5122 is a clearance hole opened for the second circuit board 52 or the third circuit board 53. In this embodiment, a first clearance hole 5121 is processed at a position where the button 020 on the second circuit board 52 and the third circuit board 53 are relatively close and concentrated. For the button 020 that is unique to the second circuit board 52 or the third circuit board 53, a second clearance hole 5122 is opened independently, thereby avoiding the clearance hole on the second support shell 51 being too large and affecting the strength of the second support shell 51.

[0106] like Figure 20 As shown, the second support shell 51 has a first side rib 513 protruding from its edge facing the panel 10, and the first side rib 513 abuts against the panel 10. By setting the first side rib 513, the second control component 50 and the panel 10 are in line contact, which reduces the mating area between the two and thus reduces the processing difficulty of the second support shell 51.

[0107] In this embodiment, the second rib 514 is a closed ring. The second support shell 51 also has a second rib 514 on the side facing the panel 10. The second rib 514 surrounds the clearance hole, thus forming a recessed platform between the first rib 513 and the second rib 514. This recessed platform is filled with adhesive and bonded to the panel 10. By bonding the second support shell 51 to the panel 10, the position of the second control component 50 can be better prevented from shifting during use, and oil fumes can be prevented from contacting the button 020, thereby ensuring the sensitivity of the button 020.
