In the description of this utility model, unless otherwise expressly limited, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] The following is combined with Figures 1 to 6 The embodiments of this application are described below.

[0027] Based on the above, this application provides a cover assembly, including a top cover 100, a sealing box 200, and a power supply box 300. The top cover 100 is provided with an air outlet 110. Specifically, when installing the cover assembly, the position of the air outlet 110 matches the position of the ventilation system inside the range hood, located on the path of the exhaust fumes. This facilitates the exhaust of internal heat and fumes along the ventilation system. After installation, the space inside the range hood can be utilized efficiently without affecting the normal exhaust function of the air outlet 110 or its connection to the ventilation system. The top cover 100 is connected to and covers the sealing box 200. The sealing box 200 is located on one side of the air outlet 110. The power box 300 is located inside the sealing box 200, which keeps the power box 300 away from the internal structure of the range hood, such as the air duct, thus preventing oil fumes and water vapor from entering the sealing box 200 and causing damage to the power box 300. The sealing box 200 is provided with a cable outlet 210 for the cable to pass through. The cable outlet 210 provides a dedicated extension channel for the cable, which is convenient for subsequent wiring.

[0028] Therefore, by placing the top cover 100 over and connecting it to the sealing box 200, it is possible to prevent impurities such as oil fumes and dust from directly entering the interior of the sealing box 200 from above. At the same time, by placing the sealing box 200 on one side of the air outlet 110, the interior of the sealing box 200 is isolated by the box body, and the exterior is isolated from other pipes or air ducts of the range hood, forming a double-layer isolation structure inside and outside the sealing box 200. This allows the power supply box 300 to be isolated from other internal environments of the range hood, thereby sealing and protecting the interior of the power supply box 300, reducing the impact of external factors on the power supply box 300, and further improving the sealing performance.

[0029] In actual use, if the sealing box 200 has a large outlet 210, the outlet 210 alone cannot completely guarantee a sealing effect. Oil fumes, moisture, etc., may still enter the sealing box 200 along the gap between the cable and the outlet 210, causing damage to the internal power supply box 300, etc. Therefore, in some specific embodiments, the sealing box 200 is provided with a sealing gasket 400, which covers the outlet 210. The sealing gasket 400 has multiple outlet holes 440, which are respectively connected to the outlet 210. By providing a sealing gasket 400, the sealing gasket 400 can be accurately placed on the outlet 210 and connected to the outlet 210 through a connector, ensuring that the outlet hole 440 corresponds to the outlet 210. Then, the cable is passed through the outlet 210 and the outlet hole 440. After that, sheet metal parts are used to connect and fix the sealing gasket 400 to the sealing box 200. This can prevent oil fumes, water vapor, etc. from entering the sealing box 200 through the gap between the outlet 210 and the cable, protect the power box 300 and other components inside the sealing box 200 from corrosion, and improve the sealing performance of the entire cover assembly.

[0030] Specifically, the sealing gasket 400 includes a first connecting portion 410 and a second connecting portion 420. The first connecting portion 410 and the second connecting portion 420 are each provided with a plurality of U-shaped holes 430. The openings of the U-shaped holes 430 of the first connecting portion 410 and the second connecting portion 420 are connected relative to each other to form a cable outlet hole 440. In this way, the size of the U-shaped holes 430 can be set according to the size of the cable, so that after connection, the cable outlet hole 440 can better adapt to the shape of different cables. After the cable is threaded through, it can tightly wrap around the cable, minimizing the gap between the cable and the cable outlet hole 440. This effectively prevents impurities such as oil fumes, moisture, and dust from entering the interior of the sealing box 200 through the gaps, improving the overall sealing performance of the sealing box 200 and further protecting the internal electrical components such as the power supply box 300 from external oil fumes.

[0031] In some embodiments, the sealed box 200 is formed by multiple side plates 230, and the top cover plate 100 is connected to the multiple side plates 230 to form a receiving cavity. The power supply box 300 is disposed in the receiving cavity, which provides a fixed installation position for the power supply box 300, making its installation more stable. During maintenance, one side plate can be opened to remove the power supply box 300. Furthermore, an upper side plate can be provided between the top of the sealed box 200 and the top cover plate 100 to further enhance the sealing performance of the power supply box 300. The connection between the top cover plate 100 and the side plates 230 forms a closed space, which can effectively isolate the power supply box 300 from external fumes, dust, etc., thereby protecting the power supply box 300.

[0032] Specifically, the top cover 100 and the sealing box 200 are both sheet metal parts or connected from sheet metal parts. The top cover 100 and the side panels 230 are both integrally molded, abandoning the traditional separate molding method, which can greatly simplify the processing flow and effectively reduce production costs. Specifically, the left and right side panels are respectively formed with bent structures, and corresponding holes are provided on the bent edges. During installation, the side panels 230 are first assembled into the sealing box 200 along the bent edges. Then, the assembled side panels are fixed with fasteners such as bolts through the corresponding holes to form a receiving cavity. The power box 300 is then placed into the receiving cavity. Subsequently, the side panel on one side is fixedly connected along the holes using fasteners to form a closed space inside the sealing box 200. In this way, the entire sealing box 200 can achieve good protection for the internal power box 300 without welding, effectively preventing the intrusion of dust, oil and other impurities.

[0033] In some embodiments, a wire passage gap 240 is provided between the power supply box 300 and at least one side plate 230, and the wire passage gap 240 communicates with the outlet 210. First, the power supply box 300 is placed in the receiving cavity of the sealing box 200, and the cable of the power supply box 300 can extend in the wire passage gap 240, with its outlet 210 corresponding to the cable route of the power supply box 300. Then, the top cover plate 100 is connected and fixed to the sealing box 200 by fasteners, so that the cable can extend out along the opening of the outlet 210 and connect to other components of the range hood.

[0034] In some embodiments, the power supply box 300 has a lifting part 310 on its outer side, and the sealing box 200 has an outer side plate 250 on the side facing the lifting part 310, with the lifting part 310 abutting against the outer side plate 250. The lifting part 310 provides a leverage point for the installation and removal of the power supply box 300. After removing the side cover, the power supply box 300 can be easily placed into or removed from the sealing box 200 by pulling the lifting part 310, without having to completely remove the range hood or cover assembly, thus improving the convenience of installation and maintenance. The abutment between the lifting part 310 and the outer side plate 250 also plays a certain role in positioning and stabilizing, ensuring the stability of the power supply box 300 after installation.

[0035] In some embodiments, the outer edge of the top cover 100 is provided with a downwardly folded edge 120. The range hood has a mounting position that is adapted to the size of the top cover 100, so that when the cover assembly is installed, the folded edge 120 naturally faces downward and abuts against the inner wall of the range hood. After the cover assembly is securely installed using fasteners, the folded edge 120 enhances the sealing of the cover assembly's edge. When the range hood is operating, it also prevents fumes from overflowing from the edge of the top cover 100, allowing the fumes to be exhausted through the air outlet 110 as much as possible.

[0036] To facilitate subsequent installation and disassembly of the cover assembly, in some embodiments, the top cover 100, sealing box 200, and folded edge 120 are provided with multiple connection holes 500 for connection with fasteners. By providing connection holes 500, after the cover assembly is fixedly connected to the range hood body using fasteners such as screws, it can be ensured that the cover assembly is securely installed and will not loosen or shift during range hood operation, facilitating later maintenance and repair.

[0037] This application also provides a range hood, including a cover assembly as described in any of the above technical solutions. For example, as shown... Figure 6 The illustrated range hood structure features a cover assembly positioned on the top of the range hood and on one side of the exhaust system. Simply connecting the cover assembly's outlet to the exhaust pipe and installing it in the corresponding position on the top of the range hood allows for quick assembly and disassembly, a secure connection, and complete sealing of the top of the range hood. Furthermore, it possesses some or all of the beneficial effects of the aforementioned cover assembly.
