[0033] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0034] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 5 ,include:

[0035] The main body of the range hood 1 has a cavity, and a partition plate 11 is provided in the cavity. The partition plate 11 divides the cavity into an independent electronic control cavity 12 and a smoke collection cavity 13. The electronic control cavity 12 is provided with functional devices. The main body of the range hood 1 is also provided with an air intake 141 that communicates with the smoke collection cavity 13.

[0036] The air collection box 2 is located on the main body 1 of the smoke machine. The air collection box 2 has an air collection chamber that is connected to the smoke collection chamber 13. The smoke exhaust fan 21 is installed in the air collection chamber. The air collection box 2 is also provided with an exhaust port that is connected to the air collection chamber.

[0037] In this invention, the electronic control cavity 12 is closer to the operating side of the main body 1 of the smoke machine than the smoke collection cavity 13, that is, the side where the user stands and operates. The functional devices are located on the inner wall of the electronic control cavity 12 away from the smoke collection cavity 13, so as to facilitate user operation.

[0038] In use, the exhaust fan 21 is started, creating negative pressure in the air collection chamber. Oil fumes enter the air collection chamber from the smoke collection chamber 13 and are further discharged under the action of the exhaust fan 21. By using a single-layer box formed by the air collection box 2 and setting a partition plate 11 to divide the cavity inside the main body of the range hood into an independent electrical control chamber 12 and a smoke collection chamber 13, the partition plate 11 replaces the internal air box in the prior art. Compared with the prior art's method of using an internal air box to form a double-layer box, this utility model uses a simple partition plate 11 to divide the cavity of the main body of the range hood, eliminating the need for a complex internal air box structure, effectively reducing material costs and manufacturing difficulty, thereby reducing the overall cost.

[0039] By using the partition plate 11, the oil fumes are isolated in the smoke collection chamber 13, preventing them from entering the electrical control chamber 12 and contaminating the functional components. This keeps the functional components clean for a long time, thus improving the technical problem that existing range hoods can easily damage the functional components inside the chamber when fumes are emitted, leading to increased cleaning and replacement costs.

[0040] The partition plate 11 physically separates the electrical control chamber 12 and the smoke collection chamber 13, providing better functional isolation and protection. For the electrical control chamber 12, it prevents impurities such as oil fumes and dust that may be present in the smoke collection chamber 13 from entering, reducing corrosion and contamination of the electrical control components, extending the service life of functional components, and ensuring the stable operation of the electrical control system. For the smoke collection chamber 13, it also avoids unnecessary interference to the smoke collection function caused by malfunctions in the electrical control components, further enhancing the independence and reliability of each functional module.

[0041] In addition, the partition plate 11 can act as a physical partition, structurally stabilizing the boundary between the two cavities and preventing deformation or mutual interference of the two cavities due to external vibrations or other factors during use. This helps maintain the stability of the entire internal structure of the range hood and ensures the normal operation of all functions.

[0042] The functional components can be lighting components, air curtain components, and air quality detection modules. The main body 1 of the range hood has air curtain inlets corresponding to the air curtain components and detection holes corresponding to the air quality detection modules. The base plate has air curtain outlets corresponding to the air curtain components and lighting windows corresponding to the lighting components. When the exhaust fan 21 is started, the air curtain components activate and form an air curtain between the user and the cooktop to prevent the escape of cooking fumes. The lighting components illuminate the area so the user can clearly see the state of the cooking ingredients. The air quality detection module monitors the air quality in real time to determine the range hood's smoke removal effect.

[0043] For the smoke hood of this utility model, please refer to [link / reference]. Figures 1 to 7The main body 1 of the range hood has a bottom plate 14, a cover plate 15, a side plate 16 and a rear plate 17. The bottom plate 14, the cover plate 15, the side plate 16 and the rear plate 17 form a cavity. The lower edge of the partition plate 11 is sealed to the bottom plate 14, the upper edge is sealed to the cover plate 15, and the side edge is sealed to the side plate 16. The air intake 141 is located on the bottom plate 14, and the air collection box 2 is located on the cover plate 15.

[0044] The base plate 14, cover plate 15, rear plate 17, and partition plate 11 together form the smoke collection chamber 13. The lower edge of the partition plate 11 is sealed to the base plate 14, the upper edge is sealed to the cover plate 15, and the side edge is sealed to the side plate 16 to prevent the oil fumes entering the smoke collection chamber 13 from entering the electrical control chamber 12 during the smoke exhaust process.

[0045] Specifically, the sealing connection between the partition plate 11 and the base plate 14, cover plate 15, and side plate 16 can all be achieved by snap-fitting to form a surface contact seal. Alternatively, sealing can be achieved by filling the surface contact areas with sealing cotton.

[0046] For the smoke hood of this utility model, please refer to [link / reference]. Figures 4 to 8 The partition plate 11 has a first connecting part 111, a second connecting part 112 and a third connecting part 113. The first connecting part 111 is located at the lower edge of the partition plate 11 and is sealed to the bottom plate 14. The second connecting part 112 is located at the upper edge of the partition plate 11 and is sealed to the cover plate 15. The third connecting part 113 is located on both sides of the partition plate 11 and is sealed to the side plate 16.

[0047] By utilizing the surface contact sealing structure formed between the first connecting part 111 and the bottom plate 14, the surface contact sealing structure formed between the second connecting part 112 and the cover plate 15, and the surface contact sealing structure formed between the third connecting part 113 and the side plate 16, it is ensured that the oil fumes entering the smoke collection chamber 13 will not enter the electronic control chamber 12 through the various structural connections.

[0048] The partition plate 11 is sealed to the bottom plate 14 via its lower edge first connecting part 11, its upper edge second connecting part 112 is sealed to the cover plate 15, and its sides third connecting parts 113 are sealed to the side plates 16 of the cavity, achieving a comprehensive seal. This effectively prevents impurities such as oil fumes and water vapor in the smoke collection chamber 13 from entering the electrical control chamber 12, avoiding corrosion, short circuits, and other damage to the electronic components in the electrical control chamber. It also prevents heat and static electricity generated by the wiring in the electrical control chamber 12 from interfering with the normal smoke collection and exhaust functions of the smoke collection chamber 13, ensuring the independence and stability of the two cavities and minimizing any adverse effects between them.

[0049] The first connecting part 111 extends toward the smoke collection chamber 13 relative to the partition plate 11 and forms a surface-contact sealing structure with the bottom plate 14. When oil accumulates in the smoke collection chamber 13, the contact surface between the first connecting part 111 extending toward the smoke collection chamber 13 and the bottom plate 14 forms a barrier to prevent oil from spreading toward the electrical control chamber 12. This barrier is a surface structure, and compared to the way the first connecting part 111 extends toward the electrical control chamber 12 in the opposite direction, the barrier structure has a larger partition area, which provides better protection against oil from the smoke collection chamber 13 entering the electrical control chamber 12.

[0050] The cross-section of the second connecting part 112 is convex, and the middle part has an upward convex structure. The cover plate 15 has a groove that fits the second connecting part 112 with the convex structure. When the oil in the smoke collection chamber 13 spreads from the contact surface between the second connecting part 112 and the cover plate 15 toward the electrical control chamber 12, the convex structure of the second connecting part 112 forms a partition. The path of the oil spreading to the electrical control chamber 12 at this point bends upward, then horizontally, and then downward, forming a stepped oil fume spread path structure, which has a better sealing effect.

[0051] The third connecting part 113 is provided in two parts, and is respectively located on both sides of the partition plate 11. The third connecting part 113 is sealed to the side plate 16 of the cavity.

[0052] For the smoke hood of this utility model, please refer to [link / reference]. Figure 4 and Figure 5 It also includes an electrical control board 3 and a main control board 4. The electrical control board 3 is located inside the electrical control cavity 12, and the functional devices are connected to the electrical control board 3. The main control board 4 is located on the top of the air collection box 2, and the electrical control board 3 and the functional devices are electrically connected to the main control board 4 through connecting lines.

[0053] By placing the electronic control board 3 inside the electronic control cavity 12, the partition plate 11 can protect the electronic control board 3, prevent oil fumes from polluting it, and reduce the maintenance cost of the electronic control board 3.

[0054] When using the range hood, the main control board 4 controls the electronic control board 3 and functional devices to operate via communication through the connecting cable.

[0055] For the smoke hood of this utility model, please refer to [link / reference]. Figures 1 to 7 The second connecting part 112 of the partition plate 11 extends into the electrical control cavity 12. The second connecting part 112 is provided with a wire hole 1121. The cover plate 15 is provided with a clearance hole 151 corresponding to the wire hole 1121. The connecting wires of the electrical control board 3 and the functional devices pass through the wire hole 1121 and the clearance hole 151 to connect with the main control board 4.

[0056] During installation, when the electronic control board 3 and functional devices are installed in the electronic control cavity 12, the connecting wires are passed through both the clearance hole 151 and the wire through hole 1121 to connect the electronic control board 3 and functional devices to the main control board 4.

[0057] Reference Figure 5 , Figure 8 as well as Figure 9 Since the second connecting part 112 extends into the electrical control cavity 12, the wire hole 1121 is connected to the electrical control cavity 12, thus preventing the wire hole 1121 from being connected to the smoke collection cavity 13 and preventing oil stains in the smoke collection cavity 13 from entering the electrical control cavity 12 through the wire hole 1121.

[0058] Reference Figure 9 The second connecting part 112, which has a "convex" shaped cross-section, has two parallel plates and a downward-opening U-shaped groove structure. One of the parallel plates is connected to the partition plate 11, and the parallel plate is also connected to the U-shaped groove structure. The wire hole 1121 is opened in both the parallel plate and the U-shaped groove structure. The wire hole 1121 is not connected to the partition plate 11, so that when the parallel plate abuts against the cover plate 15, a sealing area is formed, which further prevents the oil in the smoke collection chamber 13 from entering the electrical control chamber 12 through the wire hole 1121.

[0059] For the smoke hood of this utility model, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 6 as well as Figure 7 The cover plate 15 is provided with an air outlet 152, and the edge of the air outlet 152 extends upward with a connecting edge 153. The lower edge of the air collection box 2 extends into the air outlet 152, and the corresponding wall surface at the lower end of the air collection box 2 is connected to the connecting edge 153.

[0060] During use, the fumes enter the air collection chamber from the fume collection chamber 13. During this process, the fumes enter the air collection box 2 through the air outlet 152 on the cover plate 15. During installation, the lower edge of the air collection box 2 extends into the air outlet 152 and is sealed to the connecting edge 153 to ensure that all fumes are drawn into the air collection box 2 and prevent leakage. Specifically, the air collection box 2 and the connecting edge 153 can be connected by screws, and sealing cotton is filled on the mating surfaces to further improve the sealing performance.

[0061] Please refer to Figure 4 and Figure 6 In this utility model of a smoke hood, the air outlet 152 extends backward through the rear edge of the cover plate 15, and the rear plate 17 extends upward and connects to the corresponding side of the air collection box 2.

[0062] During installation, the lower edge of the air collection box 2 extends into the air outlet 152, and its rear edge is sealed to the rear plate 17 to ensure that the oil fumes can be drawn into the air collection box 2 and prevent exposure. Specifically, the air collection box 2 and the rear plate 17 can be connected by screws, and sealing cotton is filled on the mating surfaces to further improve the sealing performance.

[0063] For the smoke hood of this utility model, please refer to [link / reference]. Figure 2 , Figure 3 , Figure 6 as well as Figure 7 A support portion 154 is provided between the cover plate 15 and the connecting edge 153. The support portion 154 is arranged around the air outlet 152 and is recessed downward relative to the cover plate 15. The range hood also includes a surrounding plate 5, which covers the outside of the air collection box 2 and is connected to the support portion 154 at its lower end.

[0064] After extending the lower edge of the air collection box 2 into the air outlet 152 and completing the connection and installation with the connecting edge 153 and the rear plate 17, the enclosure 5 is installed. When installed on the enclosure 5, it covers the outside of the air collection box 2 and the lower end is connected to the support part 154 to form an external protection for the air collection box 2 and prevent the oil fumes inside the air collection box 2 from escaping.

[0065] The lower end of the enclosure 5 can be connected to the support part 154 by means of screwing, snap-fitting, etc.

[0066] In this utility model, the smoke hood has an avoidance hole 151 on the support part 154, and the connecting line is arranged between the enclosure 5 and the air collection box 2.

[0067] When installing the enclosure panel 5 to cover the outside of the air collection box 2, the connecting wires can be simultaneously covered inside, ensuring the connecting wires are located in the space between the enclosure panel 5 and the air collection box 2, thus maintaining an aesthetically pleasing appearance. Furthermore, the clearance hole 151 connects to the space between the enclosure panel 5 and the air collection box 2. During long-term use, if oil fumes enter the clearance hole 151, the fumes can be directed into the space between the enclosure panel 5 and the air collection box 2, preventing the fumes from escaping.

[0068] Please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The range hood of this utility model also has a control panel 6 on the main body 1.
