[0002] A range hood is an appliance used to remove cooking fumes from the kitchen. It is usually located above the stove. When the user is cooking, the range hood is turned on, and the exhaust fan creates negative pressure at the air intake. This causes the cooking fumes to enter the air collection chamber of the range hood through the air intake and then be exhausted by the range hood, preventing the user from inhaling large amounts of fumes while cooking.

[0003] Range hoods with air curtains and those with air quality detection functions are newly emerging types of range hoods. These range hoods not only have a better effect on extracting cooking fumes, but also make the purification effect of the range hood on cooking fumes visible.

[0004] However, traditional range hoods are limited to extracting cooking fumes and lack other functions such as air curtains and air quality monitoring. If users require these functions, they need to replace their range hoods, resulting in waste. Utility Model Content

[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0053] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0054] The head unit 100 of this utility model is described below with reference to the accompanying drawings.

[0055] Combination Figures 1-6 As shown, a head unit 100 according to an embodiment of the present utility model is used to connect to the main body 200 of the range hood 1000. The head unit 100 is provided with a display switch assembly 110 and a functional component 120 controlled by the display switch assembly 110. After the head unit 100 is connected to the main body 200, the display switch assembly 110 is used to control the operation of the main body 200, and the functional component 120 adds additional functions to the range hood 1000.

[0056] As can be seen from the above structure, when the user purchases a traditional range hood, by connecting the head unit 100 of this embodiment of the invention to the main body 200 of the range hood 1000, additional functions can be added to the range hood 1000 through the functional component 120. The user does not need to replace the range hood with a new one, but only needs to purchase the head unit 100. This avoids waste and saves the user the cost of purchasing the equipment.

[0057] The head unit 100 of this utility model embodiment is provided with a display switch assembly 110 and a functional component 120 controlled by the display switch assembly 110. The functional component 120 is independent of the main body 200, which facilitates the later repair, maintenance or replacement of the functional component 120, thereby reducing the difficulty of repair, maintenance and replacement of the functional component 120.

[0058] Meanwhile, since the head unit 100 is connected to the main body 200, the head unit 100 and the main body 200 form two independent components, which makes it easy to customize the head unit 100 according to the user's preferences. This allows the color of the head unit 100 to be set to the user's preferred color, or the user's preferred pattern to be added to the head unit 100, thus meeting the user's personalized needs.

[0059] Furthermore, by setting a display switch assembly 110 and a functional component 120 controlled by the display switch assembly 110 on the head unit 100, and after the head unit 100 is connected to the main body 200, the display switch assembly 110 is set to control the operation of the main body 200, and additional functions are added to the range hood 1000 through the functional component 120, the functions of the range hood 1000 can be enriched, significantly improving the user experience and product competitiveness of the range hood 1000.

[0060] It is worth noting that this application enriches the functions of the range hood 1000 by setting functional components 120 on the head unit 100. Since the head unit 100 is connected to the main body 200, compared with setting functional components 120 directly on the main body 200 to enrich the functions of the range hood 1000, it can effectively reduce the difficulty of setting functional components 120, and at the same time reduce the difficulty of repairing, maintaining and replacing functional components 120.

[0061] In some embodiments, combined with Figure 5 and Figure 8As shown, the functional component 120 includes at least one of the following: an air curtain component 121, a negative ion component 122, an air quality detection component 123, and a lighting component (the lighting component is not shown in the figure). The air curtain component 121 primarily forms an invisible air wall in front of the range hood 1000 using high-speed airflow to block the spread of cooking fumes, thereby preventing them from overflowing into other areas of the kitchen and improving the user experience. The negative ion component 122 releases negative ions, which neutralize particulate matter (such as PM2.5) in the cooking fumes, causing it to settle and reducing the harm of inhalation, thus purifying the air. Negative ions also decompose odor molecules in the cooking fumes, improving kitchen air quality and removing odors. The air quality detection component 123 uses sensors (such as PM2.5 or gas sensors) to monitor kitchen air in real time, automatically adjusting the suction level of the range hood 1000 based on the concentration of cooking fumes without manual operation, achieving intelligent adjustment of the range hood 1000 and improving its smoke-removing performance. The lighting component uses a built-in LED light module to supplement the lighting in the stove area, ensuring safety when cooking in dim lighting conditions.

[0062] In some embodiments, the lighting components may also be equipped with color temperature adjustment to match the kitchen atmosphere and enhance the functionality of the range hood 1000.

[0063] It should be noted that the negative ion unit 122 typically releases negative ions through a built-in generator to purify the air.

[0064] In a specific example, the functional component 120 includes an air curtain component 121, a negative ion component 122, an air quality detection component 123, and a lighting component. When the user starts cooking, the air quality detection component 123 can detect the concentration of cooking fumes. When the concentration of cooking fumes is detected to be high, the high airflow mode is automatically activated. At this time, the air curtain component 121 and the negative ion component 122 can also be opened simultaneously. The air curtain component 121 achieves the purpose of sealing off cooking fumes, and the negative ion component 122 can purify the escaped fine particles. In addition, the lighting component can be turned on to facilitate the user to observe the status of the food, thereby enriching the functions of the range hood 1000 and improving the user experience.

[0065] In some embodiments, the air quality detection component 123 is a PM2.5 detection component. The PM2.5 detection component is equipped with a fan. When the fan is running, it can draw outside air into the head unit 100. The PM2.5 detection component detects PM2.5 in the drawn-in outside air. When the detected PM2.5 level in the outside air exceeds a set value, the PM2.5 detection component sends a signal to the MCU (Microcontroller Unit) of the range hood 1000. After receiving the signal sent by the PM2.5 detection component, the MCU can control the range hood 1000 to increase its speed. In this way, the range hood 1000 becomes more intelligent and effectively improves its practicality and environmental friendliness.

[0066] In some embodiments, combined with Figure 1 , Figure 5 and Figure 6 As shown, the head unit 100 has a receiving cavity 1612, and the functional component 120 is disposed within the receiving cavity 1612. On the one hand, this facilitates the integration of the functional component 120 into the head unit 100, improving the integration level of the head unit 100, which helps to reduce the size of the head unit 100 and reduce the assembly difficulty between the head unit 100 and the main body 200; on the other hand, it facilitates the concealment of the functional component 120, which not only improves the aesthetics of the head unit 100, but also protects the functional component 120 and extends its service life. This, in turn, extends the service life of the head unit 100, reduces the operating cost of the head unit 100, and improves the user experience.

[0067] Optionally, combined Figure 1 , Figure 2 and Figure 4 As shown, the range hood 100 is provided with an air curtain inlet 141 and an air curtain outlet 142 corresponding to the air curtain assembly 121. This can be understood as follows: when the functional component 120 includes the air curtain assembly 121 and the air curtain assembly 121 is located within the receiving cavity 1612 of the range hood 100, the range hood 100 is provided with an air curtain inlet 141 and an air curtain outlet 142 corresponding to the air curtain assembly 121. The air curtain inlet 141 and the air curtain outlet 142 are positioned corresponding to the air curtain assembly 121 to facilitate communication between the air curtain assembly 121 and the external space of the range hood 100. This allows the air curtain assembly 121 to form an invisible air wall in front of the range hood 1000, blocking the spread of cooking fumes and, to a certain extent, preventing cooking fumes from overflowing into other areas of the kitchen, thus improving the user experience.

[0068] In specific examples, combined Figure 1 , Figure 2 and Figure 4As shown, the air curtain inlet 141 is located on the upper side of the head unit 100, and the air curtain outlet 142 is located on the lower side of the head unit 100. When the air curtain assembly 121 is running, air is drawn in through the upper air curtain inlet 141 and exhausted through the lower air curtain outlet 142 to form an air curtain located in front of the air intake of the range hood 1000. The air curtain blocks the user from the fumes and prevents the fumes from escaping into the air intake range corresponding to the user's mouth and nose.

[0069] In some embodiments, combined with Figure 1 , Figure 4 and Figure 5 As shown, the head unit 100 is provided with at least two air curtain components 121. The at least two air curtain components 121 are arranged at intervals in the left and right directions of the head unit 100. The cooperation of the at least two air curtain components 121 can expand the coverage of the air curtain, thereby improving the user experience of the head unit 100.

[0070] It should be noted that, in combination Figure 1 , Figure 4 and Figure 5 As shown, when the head unit 100 is provided with at least two air curtain components 121, the head unit 100 is simultaneously provided with at least two air curtain inlets 141 and at least two air curtain outlets 142. Each air curtain component 121 is provided with one air curtain inlet 141 and one air curtain outlet 142, thereby improving the air intake and exhaust effect of the air curtain component 121.

[0071] In some embodiments, such as Figure 5 As shown, the head unit 100 also includes a support member 190, which is disposed within the receiving cavity 1612, and the air curtain assembly 121 is disposed on the support member 190. This reduces the difficulty of fixing the air curtain assembly 121 and facilitates the use of the support member 190 to support the air curtain assembly 121, thereby improving the positional stability of the air curtain assembly 121. This not only improves the working performance of the air curtain assembly 121 but also makes the structure of the head unit 100 more stable.

[0072] The number of support members 190 is the same as the number of air curtain components 121, so that the support members 190 and the air curtain components 121 are set in a one-to-one correspondence, thereby improving the support effect of the support members 190 on the air curtain components 121.

[0073] Optionally, such as Figure 5 As shown, the negative ion component 122 is fixedly connected to the support member 190. While supporting the negative ion component 122 with the support member 190, the negative ion component 122 can also be positioned close to the air curtain component 121, so that the negative ions released by the negative ion component 122 can be discharged from the head unit 100 through the air curtain component 121, allowing the negative ions to diffuse a greater distance and achieving the purpose of purifying the air with negative ions.

[0074] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the head unit 100 is provided with a detection port 150 corresponding to the air quality detection component 123. This can be understood as follows: when the functional component 120 includes the air quality detection component 123 and the air quality detection component 123 is located in the receiving cavity 1612 of the head unit 100, the head unit 100 is provided with a detection port 150 corresponding to the air quality detection component 123, so that the air quality detection component 123 can draw air through the detection port 150 to detect the quality of the drawn-in air (e.g., detect the PM2.5 concentration in the air), which facilitates feedback on the purification effect of the range hood 1000 on the oil fumes when it is working.

[0075] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 As shown, the detection port 150 includes a first detection port 151 and a second detection port 152. One of the first detection port 151 and the second detection port 152 is formed as a detection air inlet, and the other is formed as a detection air outlet. External air flows to the air quality detection component 123 through the detection air inlet. After the air quality detection component 123 detects the air, the air is discharged through the detection air outlet.

[0076] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the detection port 150 is located at the top of the head unit 100, so that the detection port 150 is far away from the stove, which to a certain extent prevents oil fumes from entering the receiving cavity 1612 through the detection port 150, thereby improving the accuracy of air quality detection by the air quality detection component 123.

[0077] In some embodiments, the bottom of the head unit 100 is also provided with a lighting window (not shown in the example figure), which is positioned directly opposite the lighting component so that the lighting component can transmit light downwards through the lighting window, making it convenient for the user to observe the ingredients during cooking.

[0078] In some embodiments, combined with Figure 1 , Figure 5 and Figure 6As shown, the machine head 100 has a housing 160, which includes a main body 161 and a cover plate 162. The main body 161 has a receiving cavity 1612 with an opening. The cover plate 162 is detachably connected to the opening, and the functional component 120 is detachably disposed within the receiving cavity 1612. By configuring the housing 160 to include the detachably connected main body 161 and cover plate 162, and detachably connecting the cover plate 162 to the opening of the main body 161, not only is the molding difficulty of the receiving cavity 1612 reduced, but it also facilitates the formation of a relatively sealed receiving cavity 1612. Thus, when the functional component 120 is disposed within the receiving cavity 1612, the main body 161 and cover plate 162 can work together to protect the functional component 120, extending its service life.

[0079] Furthermore, by providing an opening in the receiving cavity 1612 and detachably housing the functional component 120 within the receiving cavity 1612, it is convenient to place or remove the functional component 120 from the receiving cavity 1612 through the opening, thereby reducing the difficulty of disassembling and assembling the functional component 120, and facilitating the replacement, maintenance or repair of the functional component 120, further reducing the difficulty of replacing, maintaining and repairing the functional component 120.

[0080] In a specific example, when it is necessary to replace, maintain or repair the functional component 120, the cover plate 162 can be removed from the main body 161 first, and then the functional component 120 can be removed from the receiving cavity 1612 through the opening of the receiving cavity 1612.

[0081] In some embodiments, such as Figure 5 As shown, the main body 161 has a hollow interior forming a receiving cavity 1612, which further reduces the molding difficulty of the receiving cavity 1612.

[0082] It should be noted that the detachable connection between the functional component 120 and the receiving cavity 1612 can be achieved by bolt connection or snap-fit, etc.

[0083] In some embodiments, combined with Figure 5 , Figure 6 and Figure 8 As shown, the cover plate 162 is provided with a connecting flange 1623 extending toward the main body 161, and the connecting flange 1623 is detachably connected to the main body 161. This not only enables the cover plate 162 to be detachably connected to the opening, but also reduces the difficulty of connecting the cover plate 162 to the main body 161.

[0084] The connecting flange 1623 can be detachably connected to the main body 161 by bolts.

[0085] Of course, in some other embodiments, the connecting flange 1623 may also be connected to the main body 161 in a snap-fit ​​manner to form a detachable connection.

[0086] In some embodiments, the air quality detection component 123 is disposed within the receiving cavity 1612 and adhered to the cover plate 162. This allows the air quality detection component 123 to be removed from the receiving cavity 1612 when the cover plate 162 is removed from the main body 161, facilitating repair, maintenance, or replacement of the air quality detection component 123 and reducing the difficulty of repairing, maintaining, and replacing it.

[0087] In some embodiments, combined with Figure 5 , Figure 6 and Figure 7 As shown, the machine head 100 is provided with a first connecting structure 170 for connecting to the main body 200. The first connecting structure 170 is a perforated buckle. By setting the first connecting structure 170, the machine head 100 can be connected to the main body 200, realizing the mating connection between the machine head 100 and the main body 200, and helping to reduce the assembly difficulty of the machine head 100 and the main body 200.

[0088] Meanwhile, by setting the first connecting structure 170 as a quincunx buckle, the connection performance of the first connecting structure 170 can be guaranteed, so that the first connecting structure 170 can be used to effectively realize the connection between the head 100 and the main body 200.

[0089] In some embodiments, combined with Figure 6 and Figure 7 As shown, the head 100 is also provided with an adapter plate 171. The first connecting structure 170 is connected to the head 100 through the adapter plate 171 to reduce the assembly difficulty of the first connecting structure 170 and the head 100, thereby facilitating the connection of the head 100 to the main body 200 using the first connecting structure 170.

[0090] Optionally, combined Figure 6 and Figure 7 As shown, the head 100 is provided with at least two first connecting structures 170. The at least two first connecting structures 170 are spaced apart in the length direction of the head 100. The at least two first connecting structures 170 cooperate to connect the head 100 to the main body 200, which helps to increase the connection quality between the head 100 and the main body 200 and improve the positional stability of the head 100.

[0091] Optionally, combined Figure 2 , Figure 3 and Figure 7As shown, the main body 200 is provided with a positioning hole 212 facing the first connecting structure 170. The first connecting structure 170 is adapted to be positioned and fitted in the positioning hole 212 to realize the positioning and fitting of the machine head 100 and the main body 200, reduce the connection difficulty between the machine head 100 and the main body 200, and help improve the connection quality between the machine head 100 and the main body 200.

[0092] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, the machine head 100 has a connecting plate 180, on which a second connecting structure 181 is provided. The connecting plate 180 is detachably connected to the main body 200 through the second connecting structure 181. This enables a detachable connection between the machine head 100 and the main body 200, which helps to reduce the difficulty of detachably connecting the machine head 100 and the main body 200.

[0093] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, the second connection structure 181 is the first connection hole, and the main body 200 is provided with a second connection hole 211 facing the first connection hole. The first fastener passes through the first connection hole and the second connection hole 211 in sequence and is fixedly connected to the connection plate 180 and the main body 200 respectively, thereby realizing the fixed connection between the machine head 100 and the main body 200.

[0094] Optionally, the first fastener is a first fastening bolt or a first fastening screw, etc. The first fastening bolt or the first fastening screw passes through the first connecting hole and the second connecting hole 211 in sequence and is fixedly connected to the connecting plate 180 and the main body 200 respectively, thereby realizing the detachable connection between the machine head 100 and the main body 200.

[0095] Optionally, combined Figure 2 , Figure 3 and Figure 5 As shown, the connecting plate 180 is provided with a plurality of second connecting structures 181, and the main body 200 is provided with a plurality of second connecting holes 211. The plurality of second connecting structures 181 and the plurality of second connecting holes 211 are arranged in a one-to-one correspondence. The cooperation of the plurality of second connecting structures 181 and the plurality of second connecting holes 211 helps to improve the connection strength between the machine head 100 and the main body 200, thereby improving the positional stability of the machine head 100.

[0096] In a specific example, when it is necessary to place the machine head 100 on the main body 200, the first connecting structure 170 on the machine head 100 can be positioned and fitted in the positioning hole 212 on the main body 200 to achieve the positioning fit between the machine head 100 and the main body 200. Then, the fastening bolts or fastening screws are passed through the first connecting hole and the second connecting hole 211 in sequence and fixedly connected to the connecting plate 180 and the main body 200 respectively, thereby achieving the detachable connection between the machine head 100 and the main body 200.

[0097] In some embodiments, combined with Figure 2 , Figure 5 and Figure 8 As shown, the connecting plate 180 is detachably connected to the machine head 100. This allows the connecting plate 180 to be formed as a separate structural component, reducing the molding difficulty of the connecting plate 180, thereby reducing the molding difficulty of the second connecting structure 181 on the connecting plate 180, and making it easier to reduce the connection difficulty between the machine head 100 and the main body 200.

[0098] In some embodiments, combined with Figure 2 , Figure 5 and Figure 8 As shown, the connecting plate 180 is provided with a third connecting structure 182, which is a third connecting hole. The outer shell 160 of the machine head 100 is provided with a fourth connecting hole 1622 facing the third connecting hole. The second fastener passes through the third connecting hole and the fourth connecting hole 1622 in sequence and is fixedly connected to the connecting plate 180 and the outer shell 160 of the machine head 100 respectively, thereby realizing the fixed connection of the connecting plate 180 to the machine head 100.

[0099] Optionally, the second fastener is a second fastening bolt or a second fastening screw, etc. The second fastening bolt or the second fastening screw passes through the third connecting hole and the fourth connecting hole 1622 in sequence and is fixedly connected to the connecting plate 180 and the outer shell 160 of the machine head 100 respectively, thereby realizing the detachable connection between the connecting plate 180 and the machine head 100.

[0100] Optionally, such as Figure 5 As shown, the connecting plate 180 is provided with a plurality of third connecting structures 182, and the outer shell 160 of the machine head 100 is provided with a plurality of fourth connecting holes 1622. The plurality of third connecting structures 182 and the plurality of fourth connecting holes 1622 are arranged in a one-to-one correspondence, which helps to improve the connection strength between the connecting plate 180 and the machine head 100, and thus facilitates the fixed connection between the machine head 100 and the main body 200 by using the connecting plate 180.

[0101] In some embodiments, combined with Figure 2 , Figure 5 and Figure 8As shown, the machine head 100 is provided with a mating groove 1621, and at least a portion of the connecting plate 180 is disposed within the mating groove 1621. The depth of the mating groove 1621 is adapted to the thickness of the connecting plate 180. This can also be understood as the depth of the mating groove 1621 being equal to the thickness of the connecting plate 180. Thus, when at least a portion of the connecting plate 180 is disposed within the mating groove 1621, it prevents the connecting plate 180 from protruding beyond the mating groove 1621 in the thickness direction, thereby preventing the connecting plate 180 from protruding beyond the machine head 100 in the thickness direction and improving the aesthetics of the machine head 100.

[0102] In specific examples, combined Figure 2 , Figure 5 and Figure 8 As shown, at least a portion of the top of the cover plate 162 is recessed towards the main body 161 to form a mating groove 1621. This reduces the difficulty of forming the mating groove 1621 and also allows the connecting plate 180 to be placed on the top of the machine head 100. Thus, when the machine head 100 and the main body 200 are connected using the connecting plate 180, the connection difficulty between the machine head 100 and the main body 200 is reduced compared to placing the connecting plate 180 on the bottom of the machine head 100.

[0103] The following description of an embodiment of the present invention, a smoke hood 1000, is based on the accompanying drawings.

[0104] Combination Figure 1 and Figure 2 As shown, a range hood 1000 according to an embodiment of the present utility model includes: a main body 200 and a head 100.

[0105] Among them, combined Figure 1 and Figure 2 As shown, the main body 200 has a connection position 210, and the head unit 100 is the aforementioned head unit 100. The specific structure of the head unit 100 will not be described in detail here. The head unit 100 is detachably connected to the connection position 210 of the main body 200. The display switch assembly 110 on the head unit 100 is used to control the operation of the main body 200 and the functional components 120, and to control the operation of at least some of the functions on the main body 200.

[0106] As can be seen from the above structure, the range hood 1000 of this utility model embodiment, by adopting the aforementioned head 100, can enrich the functions of the range hood 1000, reduce the maintenance and repair difficulty of the range hood 1000, and meet the personalized needs of users, effectively improving the user experience and product competitiveness of the range hood 1000.

[0107] Meanwhile, by setting a connection point 210 on the main body 200, it is beneficial to reduce the difficulty of connecting the head 100 and the main body 200.

[0108] In some embodiments, combined with Figure 2 and Figure 3 As shown, the main body 200 has a first surface 240 facing the user and a second surface 250 facing upward and located on the front side of the main body 200. The connection position 210 includes a positioning hole 212 provided on the first surface 240 for connecting the head 100 and a second connection hole 211 provided on the second surface 250 for connecting the head 100. The positioning hole 212 and the second connection hole 211 cooperate to achieve the fixation of the head 100 and the main body 200.

[0109] In some embodiments, combined with Figure 2 and Figure 3 As shown, the main body 200 has a shielding member 230, which is installed on the main body 200 after the machine head 100 is detached from the main body 200. The shielding member 230 is used to shield the connection position 210. This is to cover the positioning hole 212 and the second connection hole 211 by using the shielding member 230 to improve the aesthetics of the main body 200 after the machine head 100 is detached from the main body 200.

[0110] In some embodiments, combined with Figure 2 , Figure 3 and Figure 9 As shown, the shielding member 230 is provided with a fifth connecting hole 231, which is set opposite to the second connecting hole 211 on the main body 200, so as to facilitate the shielding member 230 to be set on the main body 200 by using the cooperation of the fifth connecting hole 231 and the second connecting hole 211, thereby reducing the difficulty of connecting the shielding member 230 and the main body 200.

[0111] In a specific example, the third fastening bolt or the third fastening screw passes through the fifth connecting hole 231 and the second connecting hole 211 in sequence and is fixedly connected to the shielding member 230 and the main body 200 respectively, thereby realizing the fixed connection between the shielding member 230 and the main body 200.

[0112] It is worth noting that both the head 100 and the shield 230 are fixedly connected to the main body 200 through the second connecting hole 211, so that the head 100 and the shield 230 share a second connecting hole 211 when fixed. This simplifies the number of connecting holes on the main body 200, which helps to simplify the structure of the main body 200. At the same time, it ensures that the head 100 and the shield 230 are positioned in the same position on the main body 200, so that after the head 100 is disassembled from the main body 200, the shield 230 can cover the connection position 210 of the head 100, improving the aesthetics of the main body 200 after the head 100 is disassembled from the main body 200.

[0113] In some embodiments, such as Figure 2As shown, the main body 200 is equipped with functional modules and a control switch assembly 220. The control switch assembly 220 controls the operation of the range hood 1000 and the functional modules. This allows the range hood 1000 to be controlled independently even when the head unit 100 is not installed on the main body 200, ensuring that the range hood 1000 has certain functions and guaranteeing its working performance.

[0114] In other words, the main body 200 of this application can be used alone or in conjunction with the head unit 100, thus enriching the flexibility of the main body 200.

[0115] It should be noted that when the main unit 200 is used alone, the control switch assembly 220 is used to control the operation of the smoke hood 1000; when the head unit 100 is connected to the main unit 200, the main unit 200 and the head unit 100 are used together, and the display switch assembly 110 is used to control the operation of the smoke hood 1000. The display switch assembly 110 can also control the operation of some functions of the functional modules.

[0116] The air quality detection component 123 mentioned above is defined as the first air quality detection component 123, and the lighting component mentioned above is defined as the first lighting component.

[0117] In some embodiments, the functional modules of the main body 200 include, but are not limited to, a second air quality detection component and a second lighting component. The function of the second air quality detection component is the same as that of the first air quality detection component 123 described above, and the function of the second lighting component is the same as that of the first lighting component described above, and will not be repeated here.

[0118] In a specific example, when the head unit 100 is connected to the main unit 200, the display switch assembly 110 controls the operation of the smoke hood 1000, controls the operation of the functional components 120 on the head unit 100, and also controls the operation of the second air quality detection component and the second lighting component of the functional module, thus enriching the functions of the smoke hood 1000.

[0119] Optionally, such as Figure 2 As shown, the main body 200 is provided with a third detection port 260 facing the second air quality detection component, so that the second air quality detection component can draw air through the third detection port 260 to detect air quality (e.g., detect the PM2.5 concentration in the air), which facilitates feedback on the purification effect of the range hood 1000 on the oil fumes when it is working.

[0120] In summary, both the head unit 100 and the main body 200 are equipped with structural components for detecting air quality. Thus, when the head unit 100 is connected to the main body 200, the air quality can be detected by using the first air quality detection component 123 on the head unit 100 alone, or by using the second air quality detection component on the main body 200 alone, or by using both the first air quality detection component 123 on the head unit 100 and the second air quality detection component on the main body 200 simultaneously.

[0121] In a specific example, when the head unit 100 is connected to the main unit 200, the first air quality detection component 123 on the head unit 100 is used first to detect the air quality. When the first air quality detection component 123 on the head unit 100 fails, the second air quality detection component on the main unit 200 is used to detect the air quality. At this time, the second air quality detection component on the main unit 200 can serve as a backup to ensure the air quality detection effect of the range hood 1000.

[0122] Specifically, the malfunction of the first air quality detection component 123 on the head unit 100 can be determined by observing whether the detection value of the first air quality detection component 123 is abnormal. Specifically, the air quality can be detected simultaneously using the first air quality detection component 123 on the head unit 100 and the second air quality detection component on the main body 200. The two values ​​are compared. If the PM2.5 value displayed by the first air quality detection component 123 on the head unit 100 is much greater than the PM2.5 value displayed by the second air quality detection component on the main body 200, then the second air quality detection component on the main body 200 may be malfunctioning. If the PM2.5 value displayed by the second air quality detection component on the main body 200 is much greater than the PM2.5 value displayed by the first air quality detection component 123 on the head unit 100, then the first air quality detection component 123 on the head unit 100 may be malfunctioning.

[0123] In some embodiments, the shielding member 230 at least partially shields the control switch assembly 220. This improves the aesthetics of the main body 200, prevents users from accidentally touching the control switch assembly 220, enhances the safety of the main body 200, and also protects the control switch assembly 220, extending its service life.

[0124] In some embodiments, combined with Figure 2 and Figure 9 As shown, the control switch assembly 220 includes a control button, and the shield 230 is provided with a clearance structure 232 for avoiding the control button. This ensures that when the shield 230 blocks the connection position 210, the control button of the control switch assembly 220 can be exposed, making it convenient to control the operation of the range hood 1000 using the control button.

[0125] The aforementioned avoidance structure 232 can be understood as an avoidance hole.

[0126] In some embodiments, combined with Figure 1 , Figure 2 and Figure 6 As shown, the main body 200 has a control switch assembly 220, which controls the operation of the main body 200. The machine head 100 is provided with a clearance opening 163 to avoid the control switch assembly 220. This avoids interference between the control switch assembly 220 and the machine head 100 when the machine head 100 is connected to the main body 200, thereby reducing the assembly difficulty of the machine head 100 and the main body 200.

[0127] In some embodiments, the main body 200 is provided with a main control module (not shown in the figure), which is electrically connected to the display switch assembly 110 via wires. Both the head unit 100 and the main body 200 are provided with wire passage ports 300 to avoid wires (the specific location and structure of the wire passage ports 300 can be determined by referring to...). Figure 2 , Figure 3 and Figure 6 (For understanding). By setting the wire passage 300 to avoid the wire, the main control module and the display switch assembly 110 can be electrically connected, and the difficulty of the electrical connection between the main control module and the display switch assembly 110 can be reduced. This makes it easier to use the main control module to control the display switch assembly 110, so that the display switch assembly 110 on the machine head 100 can control the operation of the smoke machine 1000, control the operation of the functional components 120 on the machine head 100, and control the operation of the functional modules on the main body 200, thereby ensuring the working performance of the machine head 100.

[0128] In some embodiments, combined with Figure 2 , Figure 3 and Figure 6 As shown, the cable passage 300 includes a first cable passage 310 and a second cable passage 320. The first cable passage 310 is located on the side of the head unit 100 facing the main body 200, and the second cable passage 320 is located on the side of the main body 200 facing the head unit 100. The first cable passage 310 and the second cable passage 320 are arranged opposite to each other so as to avoid the wires connecting the main control module and the display switch assembly 110 by using the first cable passage 310 and the second cable passage 320 together. This achieves the purpose of avoiding the wires by using the cable passage 300, reducing the difficulty of electrical connection between the main control module and the display switch assembly 110.
