Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and in particular to a range hood. Background Art

[0002] The range hood is an electrical appliance used to exhaust the fumes generated by the user's cooking out of the kitchen. The range hood is usually located above the stove. When the user is cooking, the range hood is started, and the exhaust fan of the range hood creates a negative pressure at the air intake of the range hood, so that the fumes generated by the user's cooking enter the air collecting chamber of the range hood through the air intake, and are then exhausted by the range hood, preventing the user from inhaling a large amount of fumes while cooking.

[0003] Range hoods with air curtains and range hoods with air quality detection functions are newly emerging range hoods. This type of range hood not only has a better effect in extracting oil fumes, but also can visualize the purification effect of the range hood on oil fumes.

[0004] However, traditional range hoods have a single function, which is only to extract oil smoke, without other functions such as air curtains, air quality detection, etc. If users need these functions, they need to replace the range hood, which is a waste. Summary of the Invention

[0061] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0062] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0063] The range hood 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0064] like Figure 1 and Figure 2 As shown, a range hood 1000 according to an embodiment of the present invention includes: a range hood body 200 and a head 100 .

[0065] like Figure 2 、 Figure 5 and Figure 6 As shown, the range hood body 200 has a first control switch assembly 220 .

[0066] like Figure 1 、 Figure 2 and Figure 7 As shown, the head 100 is detachably mounted on the range hood body 200 , and the head 100 has a second control switch assembly 110 .

[0067] The range hood body 200 has a first state for standalone use and a second state for use in conjunction with the handpiece 100. In the first state, the first control switch assembly 220 controls the operation of the range hood 1000. In the second state, the handpiece 100 is connected to the range hood body 200, and the second control switch assembly 110 controls the operation of the range hood 1000. This means that the range hood 1000 can be controlled both when the range hood body 200 is used alone and when it is used in conjunction with the handpiece 100, improving the range hood 1000's operational flexibility.

[0068] Through the above configuration, in a specific example, users can selectively use range hood 1000 based on their kitchen environment, kitchen space size, and lifestyle habits. For example, if the kitchen space is small or cooking fumes are low, the handpiece 100 can be removed from the range hood body 200 to reduce the space occupied by the range hood 1000. If cooking fumes are high or additional functions are required for the range hood 1000, the handpiece 100 can be connected to the range hood body 200 to improve the performance of the range hood 1000 and thus enhance the user experience.

[0069] It can be seen from the above structure that the range hood 1000 of the embodiment of the present invention controls the operation of the range hood 1000 by setting a first control switch assembly 220 on the range hood body 200 and a second control switch assembly 110 on the head 100, and setting the second control switch assembly 110 so that after the head 100 is connected to the range hood body 200, the range hood body 200 has a first usage state for use alone and a second usage state for use in conjunction with the head 100. That is, the range hood body 200 of the range hood 1000 can be used alone or in conjunction with the head 100, thereby improving the flexibility of use of the range hood 1000 and facilitating the enrichment of the functions of the range hood 1000. In this way, when additional functions need to be added to the range hood 1000, the user does not need to replace the range hood with a new one, but only needs to purchase the head 100, which can avoid waste and save the user the cost of purchasing the machine.

[0070] It is easy to understand that when the handpiece 100 is not connected to the range hood body 200, the range hood body 200 is a range hood with a fume extraction function and possesses all the functions of a conventional range hood. In addition to the first control switch assembly 220, the range hood body 200 also includes hardware controlled by the first control switch assembly 220, such as the smoke exhaust fan and other functional modules, and the range hood's main control module. When the handpiece 100 is connected to the range hood body 200, the first control switch assembly 220 is disconnected from the range hood body's main control module, and the second control switch assembly 110 of the handpiece 100 is connected to the range hood body's main control module. When the user operates the second control switch assembly 110, the range hood body 200 can continue to operate its original functions. After the head 100 is connected to the range hood body 200, the first control switch assembly 220 is disconnected from the main control module of the range hood body. The disconnection here can be that the wiring terminals are disconnected from each other, and then the wiring terminals of the second control switch assembly 110 are connected to the wiring terminals of the main control module. It can also be understood that after the wiring terminals of the second control switch assembly 110 are connected to the main control module, the main control module detects the second control switch assembly 110 and disconnects the circuit of the first control switch assembly 220.

[0071] At the same time, by detachably arranging the head 100 on the range hood body 200, on the first hand, it is convenient to disassemble and assemble the head 100 relative to the range hood body 200, so as to facilitate the use of the range hood body 200 alone or the combined use of the range hood body 200 and the head 100, thereby improving the flexibility of use of the range hood 1000; on the second hand, the head 100 and the range hood body 200 can also form two independent components, which is convenient for customizing the head 100 according to user preferences, so that the color of the head 100 can be set to the user's favorite color, or, the user's favorite pattern can be added to the head 100 to meet the user's personalized needs.

[0072] In summary, the range hood 1000 of the present application is not only highly flexible to use, but also rich in functions and easy to use. It can also meet the personalized needs of users and significantly improve the user experience and product competitiveness of the range hood 1000.

[0073] In some embodiments, combined Figure 5 、 Figure 6 and Figure 7As shown, the range hood body 200 includes a first functional component 270, and the handpiece 100 includes a second functional component 120. The first control switch component 220 is used to control the first functional component 270 to perform at least some of the functions of the range hood 1000, and the second control switch component 110 is used to control the second functional component 120 and part of the first functional component 270 to perform at least some of the functions of the range hood 1000. It can be understood that when the range hood body 200 is used alone, the first control switch component 220 is used to control the first functional component 270 to perform at least some of the functions of the range hood 1000, thereby ensuring the operating performance of the range hood 1000. When the range hood body 200 is used in conjunction with the handpiece 100, the second control switch component 110 is used to control the second functional component 120 and part of the first functional component 270 to perform at least some of the functions of the range hood 1000, thereby enriching the functions of the range hood 1000.

[0074] In summary, the present application not only detachably arranges the head 100 on the range hood body 200 of the range hood 1000, but also arranges a second control switch assembly 110 and a second functional assembly 120 controlled by the second control switch assembly 110 on the head 100. At the same time, after the head 100 is detachably connected to the range hood body 200, the second control switch assembly 110 is configured to control the operation of the range hood 1000, and additional functions are added to the range hood 1000 through the second functional assembly 120. This not only reduces the difficulty of enriching the functions of the range hood 1000, improves the user experience and product competitiveness of the range hood 1000, but also reduces the difficulty of maintenance, repair and replacement of the second functional assembly 120, thereby achieving the purpose of reducing the difficulty of maintenance and repair of the range hood 1000, and can meet the personalized needs of users and significantly improve the user experience.

[0075] In some embodiments, combined Figure 5 、 Figure 6 and Figure 7 As shown, the first functional assembly 270 includes at least one of a fan, a first air quality detection assembly 271, and a first lighting assembly, and the second functional assembly 120 includes at least one of an air curtain assembly 121, a negative ion assembly 122, a second air quality detection assembly 123, and a second lighting assembly. In summary, the first functional assembly 270 and the second functional assembly 120 share some of the same functions, but the handpiece 100 includes some functional components not found on the range hood body 200. This allows the handpiece 100 to enhance the functionality of the range hood 1000 and reduces the maintenance, repair, and replacement of the second functional assembly 120.

[0076] It should be noted that the main function of the fan is to form a negative pressure at the air intake of the range hood main body 200, so that the oil smoke generated by the user's cooking can enter the air collecting chamber of the range hood main body 200 through the air intake, so that the oil smoke can be discharged by the range hood main body 200, ensuring the working performance of the range hood main body 200; the first air quality detection component 271 and the second air quality detection component 123 mainly monitor the kitchen air in real time through sensors (such as PM2.5 or gas sensors, etc.), so as to automatically adjust the suction level of the range hood 1000 according to the oil smoke concentration without manual operation, thereby realizing intelligent adjustment of the range hood 1000 and improving the smoke purification performance of the range hood 1000; the first lighting component and The second lighting component mainly uses the built-in LED lighting module to fill in the light for the stove area, ensuring the safety of cooking in a dim environment; the air curtain component 121 mainly uses high-speed airflow to form an invisible wind wall in front of the range hood 1000 to block the spread of oil smoke, and thus to a certain extent prevent the oil smoke from overflowing to other areas of the kitchen during cooking, thereby improving the user experience; the function of the negative ion component 122 is to release negative ions. On the one hand, negative ions can neutralize particulate matter in oil smoke (such as PM2.5), causing it to settle, reducing the harm of inhalation, and achieving the purpose of purifying the air. On the other hand, negative ions can also decompose odor molecules in oil smoke, improve the air quality in the kitchen, and achieve the purpose of deodorization.

[0077] In some embodiments, the first lighting component and the second lighting component can also be equipped with color temperature adjustment to match the kitchen atmosphere and enrich the functions of the range hood 1000; the negative ion component 122 usually releases negative ions through a built-in generator to achieve the purpose of purifying the air.

[0078] In some embodiments, the first air quality detection component 271 and the second air quality detection component 123 are both PM2.5 detection components. The PM2.5 detection component is equipped with a fan. When the fan is running, it can suck the outside air into the range hood 1000. The PM2.5 detection component performs PM2.5 detection on the sucked outside air. When it is detected that the PM2.5 of the outside air exceeds the set value, the PM2.5 detection component will send 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 gear of the range hood 1000 to increase. In this way, the range hood 1000 becomes more intelligent and effectively improves the practicality and environmental protection of the range hood 1000.

[0079] In a specific example, the second functional component 120 also includes an air curtain component 121, a negative ion component 122, a second air quality detection component 123 and a second lighting component, so that the head 100 can effectively enrich the functions of the range hood 1000, while also reducing the difficulty of maintenance, repair and replacement of the air curtain component 121, the negative ion component 122, the second air quality detection component 123 and the second lighting component.

[0080] Through the above settings, when the user starts cooking, the second air quality detection component 123 can be used to sense the oil fume concentration. When the oil fume concentration is sensed to be increasing, the high air volume mode is automatically started. At this time, the wind curtain component 121 and the negative ion component 122 can also be turned on synchronously. The wind curtain component 121 can achieve the purpose of blocking the oil fume, and the negative ion component 122 can purify the escaping fine particles. In addition, the second lighting component can also be turned on to facilitate the user to observe the status of food, thereby enriching the functions of the range hood 1000 and improving the user experience.

[0081] In some embodiments, in the second usage state, the second air quality detection component 123 detects air quality and / or the first air quality detection component 271 detects air quality. It can be understood that when the handpiece 100 is connected to the range hood body 200, the second air quality detection component 123 on the handpiece 100 can be used alone to detect air quality, the first air quality detection component 271 on the range hood body 200 can be used alone to detect air quality, or both the second air quality detection component 123 on the handpiece 100 and the first air quality detection component 271 on the range hood body 200 can be used simultaneously to detect air quality, thereby ensuring effective air quality detection and facilitating automatic adjustment of the suction level of the range hood 1000 according to the oil fume concentration, achieving intelligent adjustment of the range hood 1000, and improving the smoke purification performance of the range hood 1000.

[0082] In a specific example, when the head 100 is connected to the range hood body 200, the second air quality detection component 123 on the head 100 is used first to detect the air quality. When the second air quality detection component 123 on the head 100 fails, the first air quality detection component 271 on the range hood body 200 is used to detect the air quality. At this time, the first air quality detection component 271 on the range hood body 200 can serve as a backup to ensure the air quality detection effect of the range hood 1000.

[0083] Among them, whether the second air quality detection component 123 on the head 100 is faulty can be judged by observing whether the detection value of the second air quality detection component 123 is abnormal. Specifically, the second air quality detection component 123 on the head 100 and the first air quality detection component 271 on the range hood body 200 can be used simultaneously to detect the air quality respectively, and the values of the two can be compared. If the PM2.5 value displayed by the second air quality detection component 123 on the head 100 is much larger than the PM2.5 value displayed by the first air quality detection component 271 on the range hood body 200, it is judged that the first air quality detection component 271 on the range hood body 200 may be faulty; if the PM2.5 value displayed by the first air quality detection component 271 on the range hood body 200 is much larger than the PM2.5 value displayed by the second air quality detection component 123 on the head 100, it is judged that the second air quality detection component 123 on the head 100 may be faulty.

[0084] In some embodiments, combined Figure 4 、 Figure 5 and Figure 6 As shown, the range hood body 200 includes a panel 280, which is provided with a mounting cavity 290. The first air quality detection assembly 271 is disposed within the mounting cavity 290. The panel 280 can shield the first air quality detection assembly 271. This not only improves the aesthetics of the range hood body 200 but also protects the first air quality detection assembly 271.

[0085] Optionally, combined Figure 4 、 Figure 5 and Figure 6 As shown, a first detection port 260 facing the first air quality detection component 271 is provided on the enclosure 280, so that the first air quality detection component 271 can draw air through the first detection port 260 to detect the air quality (such as: detecting the PM2.5 concentration in the air), which is convenient for feedback on the purification effect of the oil fume when the range hood 1000 is working.

[0086] In some embodiments, combined Figure 7 、 Figure 8 and Figure 10 As shown, the handpiece 100 has a receiving cavity 1612, and the second functional component 120 is disposed in the receiving cavity 1612. On the one hand, this facilitates the integration of the second functional component 120 into the handpiece 100, thereby improving the integration level of the handpiece 100, reducing the volume of the handpiece 100, and reducing the difficulty of assembling the handpiece 100 with the range hood body 200. On the other hand, it facilitates the concealment of the second functional component 120, which not only improves the aesthetics of the handpiece 100 but also protects the second functional component 120 and extends its service life. This, in turn, extends the service life of the handpiece 100, reduces the cost of using the handpiece 100, and enhances the user experience.

[0087] Optionally, combined Figure 7 、 Figure 10 and Figure 11 As shown, the head 100 is provided with an air curtain inlet 141 and an air curtain outlet 142 corresponding to the air curtain assembly 121. It can be understood here that when the second functional component 120 includes the air curtain assembly 121 and the air curtain assembly 121 is arranged in the accommodating cavity 1612 of the head 100, the head 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 arranged corresponding to the air curtain assembly 121 to facilitate the communication between the air curtain assembly 121 and the external space of the head 100, thereby facilitating the use of the air curtain assembly 121 to form an invisible wind wall in front of the range hood 1000 to block the spread of oil smoke, thereby preventing oil smoke from overflowing to other areas of the kitchen during cooking to a certain extent, and improving the user experience.

[0088] In a specific example, combining Figure 7 、 Figure 10 and Figure 11 As shown, the wind curtain inlet 141 is arranged on the upper side of the machine head 100, and the wind curtain outlet 142 is arranged on the lower side of the machine head 100. When the wind curtain assembly 121 is running, air is taken in through the wind curtain inlet 141 on the upper side, and air is exhausted through the wind curtain outlet 142 on the lower side to form a wind curtain located in front of the air intake of the range hood 1000. The wind curtain blocks the user from the oil smoke and prevents the oil smoke from escaping to the inhalation range corresponding to the user's mouth and nose.

[0089] In some embodiments, combined Figure 7 and Figure 10 As shown, at least two air curtain assemblies 121 are provided on the head 100 , and the at least two air curtain assemblies 121 are spaced apart in the left and right directions of the head 100 . The cooperation of the at least two air curtain assemblies 121 can expand the coverage of the air curtain, thereby improving the user experience of the head 100 .

[0090] It should be noted that, combined with Figure 7 、 Figure 10 and Figure 11 As shown, when at least two air curtain assemblies 121 are provided on the head 100, at least two air curtain inlets 141 and at least two air curtain outlets 142 are respectively provided on the head 100, and each air curtain assembly 121 corresponds to a separate air curtain inlet 141 and a air curtain outlet 142, thereby improving the air inlet and outlet effects of the air curtain assembly 121.

[0091] In some embodiments, as Figure 7As shown, the handpiece 100 further includes a support member 190, which is disposed within the accommodating cavity 1612, and the air curtain assembly 121 is disposed on the support member 190. This not only reduces the difficulty of securing the air curtain assembly 121, but also 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 stabilizes the structure of the handpiece 100.

[0092] The number of the supporting members 190 is consistent with the number of the air curtain assemblies 121 , so that the supporting members 190 and the air curtain assemblies 121 are arranged in a one-to-one correspondence, thereby improving the supporting effect of the supporting members 190 on the air curtain assemblies 121 .

[0093] Alternatively, as Figure 7 As shown, the negative ion assembly 122 is fixedly connected to the support member 190. While the negative ion assembly 122 is supported by the support member 190, the negative ion assembly 122 can also be placed close to the air curtain assembly 121, so that the negative ions released by the negative ion assembly 122 can be discharged from the head 100 through the air curtain assembly 121, so that the negative ions can diffuse farther, thereby achieving the purpose of using negative ions to purify the air.

[0094] Optionally, combined Figure 2 、 Figure 7 and Figure 10 As shown, a detection port 150 corresponding to the second air quality detection component 123 is provided on the handpiece 100. It can be understood here that when the second functional component 120 includes the second air quality detection component 123 and the second air quality detection component 123 is provided in the accommodating cavity 1612 of the handpiece 100, a detection port 150 corresponding to the second air quality detection component 123 is provided on the handpiece 100, so that the second air quality detection component 123 can inhale air through the detection port 150 to detect the quality of the inhaled air (such as: detecting the PM2.5 concentration in the air), which is convenient for feedback on the purification effect of the oil fume when the range hood 1000 is working.

[0095] In some embodiments, combined Figure 2 、 Figure 7 and Figure 10 As shown, the detection port 150 includes a second detection port 151 and a third detection port 152. One of the second detection port 151 and the third detection port 152 is formed as a detection air inlet, and the other is formed as a detection air outlet. The external air flows to the second air quality detection component 123 through the detection air inlet. After the second air quality detection component 123 detects the air, the air is discharged through the detection air outlet.

[0096] In the description of the present invention, features defined as "first", "second" and "third" may explicitly or implicitly include one or more such features, and are used to distinguish and describe features, without any distinction in order or importance.

[0097] Optionally, combined Figure 2 、 Figure 7 and Figure 10 As shown, the detection port 150 is located at the top of the head 100, so that the detection port 150 is set away from the stove, which to a certain extent prevents oil smoke from entering the accommodating cavity 1612 through the detection port 150, thereby improving the accuracy of the second air quality detection component 123 in detecting air quality.

[0098] In some embodiments, a lighting window (not shown in the example diagram) is further provided at the bottom of the head 100, and the lighting window is arranged opposite the second lighting component so that the second lighting component can transmit light downward through the lighting window, making it convenient for the user to observe the ingredients being cooked.

[0099] In some embodiments, combined Figure 7 、 Figure 8 and Figure 10 As shown, the handpiece 100 includes a housing 160, which includes a main body 161 and a cover 162. The main body 161 has a receiving cavity 1612, which is open. The cover 162 is detachably connected to the opening, and the second functional component 120 is detachably disposed in the receiving cavity 1612. By configuring the housing 160 to include a detachably connected main body 161 and cover 162, and detachably connecting the cover 162 to the opening of the main body 161, not only is the difficulty of molding the receiving cavity 1612 reduced, but also the relatively sealed receiving cavity 1612 is formed. In this way, when the second functional component 120 is disposed in the receiving cavity 1612, the main body 161 and cover 162 can cooperate to protect the second functional component 120, thereby extending the service life of the second functional component 120.

[0100] In addition, by setting the accommodating cavity 1612 to have an opening and detachably arranging the second functional component 120 in the accommodating cavity 1612, the second functional component 120 can be conveniently placed in or removed from the accommodating cavity 1612 through the opening, thereby reducing the difficulty of disassembling and assembling the second functional component 120, thereby facilitating the replacement, maintenance or repair of the second functional component 120, and further reducing the difficulty of replacing, maintaining and repairing the second functional component 120.

[0101] In a specific example, when the second functional component 120 needs to be replaced, maintained or repaired, the cover 162 can be removed from the main body 161 first, and then the second functional component 120 can be removed from the accommodating cavity 1612 through the opening of the accommodating cavity 1612.

[0102] In some embodiments, as Figure 7 As shown, the interior of the main body 161 is hollow to form an accommodating cavity 1612 , so as to further reduce the difficulty of molding the accommodating cavity 1612 .

[0103] It should be noted that the detachable connection between the second functional component 120 and the accommodating cavity 1612 mentioned here can be achieved by bolt connection or clamping.

[0104] In some embodiments, combined Figure 7 、 Figure 8 and Figure 10 As shown, the cover 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 realizes the detachable connection of the cover 162 to the opening, but also reduces the difficulty of connecting the cover 162 to the main body 161.

[0105] The connecting flange 1623 can be detachably connected to the main body 161 by bolts.

[0106] Of course, in some other embodiments, the connecting flange 1623 may also be connected to the main body 161 in a detachable manner by means of a snap connection.

[0107] In some embodiments, the second air quality detection assembly 123 is disposed in the accommodating cavity 1612 and bonded to the cover plate 162. Thus, when the cover plate 162 is removed from the main body 161, the second air quality detection assembly 123 can be removed from the accommodating cavity 1612, thereby facilitating repair, maintenance, or replacement of the second air quality detection assembly 123 and reducing the difficulty of repairing, maintaining, and replacing the second air quality detection assembly 123.

[0108] In some embodiments, combined Figure 2 and Figure 3 As shown, the range hood body 200 and the handpiece 100 are connected via a connecting assembly 213. This connection between the handpiece 100 and the range hood body 200 allows the handpiece 100 to be connected to the range hood body 200, ensuring the strength of the connection between the handpiece 100 and the range hood body 200 while also reducing the difficulty of connecting the handpiece 100 and the range hood body 200.

[0109] In some embodiments, combined Figure 2 and Figure 3As shown, the connection assembly 213 includes at least one of a fixing member 2131, a positioning member 2132, and a avoiding member 2133. The fixing member 2131 is used to fix the handpiece 100 to the range hood body 200, the positioning member 2132 is used to position the handpiece 100 and the range hood body 200, and the avoiding member 2133 is used to avoid the wiring harness connecting the handpiece 100 and the range hood body 200 and / or avoid at least part of the structure of the range hood body 200. Through this arrangement, the fixing member 2131 and the positioning member 2132 can cooperate to achieve a mechanical connection between the range hood body 200 and the handpiece 100.

[0110] At the same time, when a avoidance member 2133 for avoiding the wiring harness connecting the head 100 is provided, it is convenient to realize the electrical connection between the range hood body 200 and the head 100. In this way, when the head 100 is connected to the range hood body 200, the second control switch component 110 of the head 100 can be used to control the second functional component 120 and part of the first functional component 270 to perform at least part of the function of the range hood 1000.

[0111] In addition, when an avoidance member 2133 is provided to avoid at least part of the structure of the range hood body 200, it can to a certain extent prevent at least part of the structure of the range hood body 200 from interfering with the head 100 when the head 100 is connected to the range hood body 200, thereby reducing the difficulty of assembling the head 100 and the range hood body 200.

[0112] In some embodiments, combined Figure 2 、 Figure 3 and Figure 7 As shown, the fixing member 2131 includes a connecting plate 180. The range hood body 200 is provided with a first connecting portion 291, and the handpiece 100 is provided with a second connecting portion 1621. The connecting plate 180 is connected to the first connecting portion 291 and the second connecting portion 1621 via fasteners. This facilitates the use of the connecting plate 180 to achieve a mating connection between the handpiece 100 and the range hood body 200, allowing the handpiece 100 to be connected to the range hood body 200. This ensures the strength of the connection between the handpiece 100 and the range hood body 200 while also reducing the difficulty of connecting the two.

[0113] In some embodiments, combined Figure 2 、 Figure 3 and Figure 7As shown, the connecting plate 180 is provided with a first connecting hole 181 and a second connecting hole 182, the first connecting portion 291 of the range hood body 200 is provided with a first fixing hole 211 facing the first connecting hole 181, and the second connecting portion 1621 of the head 100 is provided with a second fixing hole 1622 facing the second connecting hole 182, and the fastener includes a first fastener and a second fastener, the first fastener sequentially passes through the first connecting hole 181 and the first fixing hole 211 and is fixedly connected to the connecting plate 180 and the range hood body 200, respectively, thereby achieving connection. The plate 180 is fixedly connected to the range hood body 200; the second fastener passes through the second connecting hole 182 and the second fixing hole 1622 in sequence and is fixedly connected to the connecting plate 180 and the head 100 respectively, thereby realizing the fixed connection between the connecting plate 180 and the head 100, thereby realizing the coordinated connection between the head 100 and the range hood body 200, so that the head 100 can be connected to the range hood body 200, while ensuring the connection strength between the head 100 and the range hood body 200, it can also reduce the difficulty of connecting the head 100 and the range hood body 200.

[0114] Optionally, the fastener is a fastening bolt or a fastening screw.

[0115] Optionally, combined Figure 2 、 Figure 3 and Figure 8 As shown, the range hood body 200 is provided with a plurality of first fixing holes 211, and the connecting plate 180 is provided with a plurality of first connecting holes 181, and the plurality of first connecting holes 181 and the plurality of first fixing holes 211 are arranged in a one-to-one correspondence, and the cooperation between the plurality of first connecting holes 181 and the plurality of first fixing holes 211 is conducive to improving the connection strength between the connecting plate 180 and the range hood body 200; the connecting plate 180 is provided with a plurality of second connecting holes 182, and the head 100 is provided with a plurality of second fixing holes 1622, and the plurality of second connecting holes 182 and the plurality of second fixing holes 1622 are arranged in a one-to-one correspondence, and the cooperation between the plurality of second connecting holes 182 and the plurality of second fixing holes 1622 is conducive to improving the connection strength between the connecting plate 180 and the head 100, thereby facilitating the use of the connecting plate 180 to achieve a fixed connection between the head 100 and the range hood body 200, thereby improving the positional stability of the head 100.

[0116] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0117] In some embodiments, combined Figure 3 and Figure 7As shown, the first connecting portion 291 is a first mating groove provided on the range hood body 200, the second connecting portion 1621 is a second mating groove provided on the head 100, and the connecting plate 180 is respectively provided in the first mating groove and the second mating groove. The groove depths of the first mating groove and the second mating groove are both adapted to the thickness of the connecting plate 180. It can also be understood here that the groove depths of the first mating groove and the second mating groove are both equal to the thickness of the connecting plate 180. In this way, when the connecting plate 180 is provided in the first and second mating grooves, it can be prevented from protruding from the first and second mating grooves in the thickness direction of the connecting plate 180, thereby improving the aesthetics of the range hood 1000.

[0118] In some embodiments, combined Figure 2 、 Figure 3 、 Figure 8 and Figure 9 As shown, the positioning member 2132 includes a first positioning member 170 and a second positioning member 212. The first positioning member 170 is a plum blossom buckle, and the second positioning member 212 is a positioning hole. The plum blossom buckle can be positioned and fitted in the positioning hole. One of the first positioning member 170 and the second positioning member 212 is provided on the range hood body 200, and the other is provided on the handpiece 100. This facilitates the coordinated connection between the first positioning member 170 and the second positioning member 212 to achieve the coordinated connection between the handpiece 100 and the range hood body 200, thereby allowing the handpiece 100 to be connected to the range hood body 200. While ensuring the connection strength between the handpiece 100 and the range hood body 200, it can also reduce the difficulty of connecting the handpiece 100 and the range hood body 200.

[0119] In a specific example, combining Figure 2 、 Figure 3 、 Figure 8 and Figure 9 As shown, the second positioning member 212 is provided on the range hood body 200 , and the first positioning member 170 is provided on the head 100 .

[0120] Of course, in some other embodiments, the first positioning member 170 may also be provided on the range hood body 200 , and the second positioning member 212 may be provided on the head 100 (not shown in this example figure).

[0121] In some embodiments, combined Figure 2 and Figure 3As shown, the range hood body 200 has a first surface 240 facing the user side, the second positioning member 212 is arranged on the first surface 240, the range hood body 200 has a second surface 250 facing upward and located on the front side of the range hood body 200, and the first fixing hole 211 is arranged on the second surface 250, so that the second positioning member 212 and the first fixing hole 211 are arranged on different surfaces of the range hood body 200, which not only avoids interference between the second positioning member 212 and the first fixing hole 211, but also enables the head 100 to be connected to different surfaces of the range hood body 200, thereby improving the connection strength between the head 100 and the range hood body 200.

[0122] Optionally, combined Figure 2 、 Figure 3 and Figure 8 As shown, at least two second positioning members 212 are provided on the first surface 240, and the at least two second positioning members 212 are spaced apart in the left and right directions of the range hood body 200. At least two first positioning members 170 are provided on the head 100. The at least two second positioning members 212 and the at least two first positioning members 170 correspond one-to-one to connect the head 100 to the range hood body 200, which is beneficial to increase the connection quality between the head 100 and the range hood body 200 and improve the position stability of the head 100.

[0123] Through the above-mentioned setting, in a specific example, when the head 100 needs to be set on the range hood body 200, the first positioning member 170 on the head 100 can be first positioned and matched in the second positioning member 212 on the range hood body 200 to achieve the positioning and matching of the head 100 and the range hood body 200, and then the connecting plate 180 is respectively connected to the first connecting part 291 and the second connecting part 1621 through fasteners, thereby achieving a fixed connection between the head 100 and the range hood body 200.

[0124] In some embodiments, combined Figure 8 and Figure 9 As shown, an adapter plate 171 is also provided on the head 100, and the first positioning member 170 is connected to the head 100 through the adapter plate 171 to reduce the difficulty of assembling the first positioning member 170 and the head 100, thereby facilitating the use of the first positioning member 170 to connect the head 100 to the range hood body 200.

[0125] Optionally, combined Figure 2 、 Figure 3 and Figure 8As shown, the avoidance member 2133 includes a first avoidance opening 320 and a second avoidance opening 310. The first avoidance opening 320 is provided on the range hood body 200, and the second avoidance opening 310 is provided on the handpiece 100. The first avoidance opening 320 and the second avoidance opening 310 are arranged opposite each other. The first avoidance opening 320 and the second avoidance opening 310 avoid the wiring harness connecting the handpiece 100 and the range hood body 200. This simplifies the difficulty of electrical connection between the main control module and the second control switch assembly 110.

[0126] In a specific example, a main control module (not shown in the figure) is provided on the range hood body 200 , and the main control module is electrically connected to the second control switch assembly 110 via a wire passing through the first avoidance opening 320 and the second avoidance opening 310 .

[0127] In some embodiments, combined Figure 7 、 Figure 8 and Figure 10 As shown, the handpiece 100 is provided with a third clearance opening 163. In the second operating state, the third clearance opening 163 clears at least a portion of the first control switch assembly 220. This, to a certain extent, prevents interference between the first control switch assembly 220 and the handpiece 100 when the handpiece 100 is connected to the range hood body 200, thereby reducing the difficulty of assembling the handpiece 100 and the range hood body 200.

[0128] In some embodiments, combined Figure 5 and Figure 6 As shown, the range hood 1000 further includes a shielding member 230. In a first usage state, the shielding member 230 is connected to the range hood body 200. The shielding member 230 at least shields the connection point 210 between the range hood body 200 and the handpiece 100. This prevents the user from directly observing the connection point 210 when the range hood 1000 is used alone, thereby preventing the integrity of the range hood 1000 from being affected. Furthermore, the shielding member 230 shields the connection point 210, thereby improving the safety of the range hood body 200.

[0129] In some embodiments, combined Figure 5 and Figure 6 As shown, the main body 200 of the range hood is provided with a connection position 210, which is suitable for connecting with the head 100 provided with the second functional component 120 (the specific structure of the head 100 can be seen in Figure 7-10 Thus, the range hood body 200 can be externally connected to the handpiece 100, so that the range hood body 200 of the present application can be used not only alone but also in conjunction with the handpiece 100, thereby improving the flexibility of the range hood 1000 and reducing the difficulty of connecting the range hood body 200 and the handpiece 100.

[0130] In some embodiments, combined Figure 5 and Figure 6As shown, the shielding member 230 simultaneously shields the first fixing hole 211, the second positioning member 212 and the first avoidance opening 320 to prevent the first fixing hole 211, the second positioning member 212 and the first avoidance opening 320 from being exposed when the range hood body 200 is used alone, thereby making the appearance of the range hood body 200 complete and improving the aesthetics of the range hood body 200.

[0131] In some embodiments, the shielding member 230 at least avoids the operating portion of the first control switch assembly 220. This prevents the shielding member 230 from interfering with the user's operation of the operating portion of the first control switch assembly 220, thereby enabling the first control switch assembly 220 to control the operation of the range hood body 200 and ensure the operating performance of the range hood body 200 itself.

[0132] In some embodiments, combined Figure 5 and Figure 6 As shown, the first control switch assembly 220 includes a control button 221, and the shielding member 230 is provided with an avoidance structure 232 for avoiding the control button 221. This ensures that when the shielding member 230 blocks the connection position 210, the user can directly access the control button 221 of the first control switch assembly 220, and conveniently use the control button 221 to control the operation of the range hood body 200.

[0133] The avoidance structure 232 mentioned above can be understood as an avoidance hole.

[0134] In some embodiments, combined Figure 5 and Figure 6 As shown, a third connecting hole 231 is provided on the shielding member 230, and the third connecting hole 231 is arranged opposite to the first fixing hole 211 on the range hood body 200, so that the shielding member 230 can be set on the range hood body 200 by utilizing the third connecting hole 231 and the first fixing hole 211, thereby reducing the difficulty of connecting the shielding member 230 with the range hood body 200.

[0135] In a specific example, the third fastener passes through the third connection hole 231 and the first fixing hole 211 in sequence and is fixedly connected to the shielding member 230 and the range hood body 200 respectively, thereby achieving a fixed connection between the shielding member 230 and the range hood body 200 .

[0136] The third fastening member is a third fastening bolt or a third fastening screw.

[0137] It is worth noting that the head 100 and the shielding member 230 are both fixedly connected to the range hood body 200 through the first fixing hole 211, so that the head 100 and the shielding member 230 share a connecting structure (the first fixing hole 211) when fixed. This can simplify the number of connecting structures on the range hood body 200, which is conducive to simplifying the structure of the range hood body 200. At the same time, the head 100 and the shielding member 230 are set in the same position on the range hood body 200, ensuring that after the head 100 is disassembled relative to the range hood body 200, the shielding member 230 can cover the connection position 210 of the head 100, thereby improving the aesthetics of the range hood body 200 after the head 100 is disassembled relative to the range hood body 200.

[0138] In a specific example, combining Figure 5 and Figure 6 As shown, at least a portion of the first surface 240 is recessed toward the rear side of the range hood body 200 to form a third matching groove, and at least a portion of the second surface 250 is recessed toward the bottom of the range hood body 200 to form a first connecting portion 291. The first connecting portion 291 is formed as a first matching groove. The shielding member 230 includes a first shielding member 233 and a second shielding member 234. The first shielding member 233 is arranged in the third matching groove, and the second shielding member 234 is arranged in the first matching groove, thereby achieving the purpose of using the shielding member 230 to shield the connection position 210 and improving the position stability of the shielding member 230.

[0139] Optionally, the groove depth of the third mating groove is equal to the thickness of the first covering member 233, and the groove depth of the first mating groove is equal to the thickness of the second covering member 234. In this way, when the covering member 230 is connected to the range hood body 200, the covering member 230 can be prevented from protruding from the range hood body 200, thereby improving the aesthetics of the range hood body 200.

[0140] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0141] Figure 7 Three first connection holes 181 and three second connection holes 182 are shown for illustrative purposes, but after reading the above technical solution, ordinary technicians can obviously understand that the solution can be applied to the technical solution of three, four or more first connection holes 181 and second connection holes 182, which also falls within the scope of protection of the present invention.

[0142] Other components of the range hood 1000 according to the embodiment of the present invention, such as the specific structure of the air curtain assembly 121, are well known to those skilled in the art and will not be described in detail here.
