[0038] Reference Figures 1 to 7 In one embodiment of the utility model, a range hood is provided, which includes a body 100, a box body 300 and a cover body 400. The body 100 has a smoke collecting chamber 110, and a top plate 200 of the smoke collecting chamber 110 is provided with a mounting hole 210, and the top plate 200 is also provided with a grounding portion 220. The box body 300 is installed in the mounting hole 210 and extends into the smoke collecting chamber 110, and the box body 300 has a receiving chamber 310, and a mounting opening connected to the receiving chamber 310 is also provided on the top wall of the box body 300. The cover body 400 is installed on the top plate 200 and closes the mounting opening. Among them, the side wall of the box body 300 is provided with a first wire hole 320 connecting the smoke collecting chamber 110 and the receiving chamber 310, and the top plate 200 is provided with a second wire hole 230 located on one side of the grounding portion 220. The ground wire in the accommodating cavity 310 can pass through the first wire hole 320 and the second wire hole 230 in sequence to connect to the grounding portion 220 . The cover 400 shields the second wire hole 230 and the grounding portion 220 , and can shield the ground wire.

[0039] In the above structure, electrical components such as the power board can be placed in the accommodating cavity 310 of the box body 300, and the ground wire can pass through the first wire hole 320 on the side wall of the box body 300 to the smoke collecting cavity 110, and then pass upward from the second wire hole 230 of the top plate 200, and finally connect to the grounding portion 220 on the top plate 200. Since the cover body 400 is installed on the box body 300 or the top plate 200 and can block the second wire hole 230 and the grounding portion 220, and at the same time can block the ground wire passing from the second wire hole 230 to the grounding portion 220, the ground wire can be confined below the cover body 400, thereby preventing the ground wire from being directly exposed to the outside of the body 100, which not only makes the appearance of the range hood more beautiful, but also protects the ground wire, improves the reliability of grounding of the ground wire, and thus improves the safety of the range hood.

[0040] It is understandable that the second wire hole 230 is provided on the top plate 200, which is only for Figures 1 to 7 As an exemplary illustration, in some embodiments, the second wire hole 230 can also be directly opened on the periphery of the installation opening of the box body 300, so that the ground wire that passes through the first wire hole 320 to the smoke collecting chamber 110 can still pass through the second wire hole 230 upwards and finally be connected to the grounding portion 220 on the top plate 200.

[0041] It is understandable that the cover 400 is installed on the top plate 200, which is only for Figures 1 to 7 As an exemplary illustration, in some embodiments, the cover body 400 can also be directly installed on the box body 300 and close the installation port. The utility model does not make any specific limitation on this. It only needs that the cover body 400 can cover the second wire hole 230 and the grounding portion 220 and the ground wire passing through the second wire hole 230 to the grounding portion 220.

[0042] It is understandable that, referring to Figures 1 to 10 The side wall of the box body 300 is provided with two first wire holes 320, so that, in addition to passing the ground wire through the first wire hole 320 to the smoke collecting chamber 110, the wires of other electrical components can also be passed through the first wire hole 320 to the smoke collecting chamber 110 and then connected to the corresponding positions. Therefore, the number of the first wire holes 320 can be one, two, three or more, and the utility model does not make specific limitations on this.

[0043] It is understandable that the grounding portion 220 may specifically be a grounding terminal or a grounding screw disposed on the upper surface of the top plate 200 , and the present invention does not make any specific limitation on this.

[0044] It is understandable that the box body 300 and the cover body 400 can be made of plastic.

[0045] Reference Figures 1 to 7In some embodiments, a mounting groove 240 is provided on the upper surface of the top plate 200 , the mounting hole 210 , the second wire hole 230 , and the grounding portion 220 are all located on the bottom wall of the mounting groove 240 , and the cover body 400 is installed in the mounting groove 240 and covers the mounting groove 240 .

[0046] In the above structure, the setting of the installation groove 240 can facilitate the positioning and installation of the cover body 400, thereby ensuring that after the cover body 400 is installed, it can cover the second wire hole 230 and the grounding portion 220 as well as the ground wire passing from the second wire hole 230 to the grounding portion 220, thereby limiting the ground wire to the bottom of the cover body 400, avoiding the ground wire from being directly exposed to the outside of the body 100, and thus being able to protect the ground wire, improve the reliability of the grounding of the ground wire, and thereby improve the safety of the range hood.

[0047] It is understandable that the cover body 400 is installed in the installation groove 240 and covers the installation groove 240. Specifically, the cover body 400 can be embedded in the installation groove 240, or the outer surface of the cover body 400 is flush with the upper surface of the top plate 200, thereby increasing the aesthetics of the range hood.

[0048] Reference Figures 1 to 11 In some embodiments, at least one plug plate 410 extending outward is provided on one side of the cover body 400, at least one first fastening hole 420 is provided on the surface of the cover body 400, a plug hole 250 corresponding to the plug plate 410 is provided on the side wall or bottom wall of the mounting groove 240, and a second fastening hole 260 corresponding to the first fastening hole 420 is also provided on the bottom wall of the mounting groove 240.

[0049] In the above structure, during installation, the plug plate 410 of the cover body 400 is first inserted into the corresponding slot, so that the cover body 400 is positioned and placed in the installation slot 240, and then the fastener is sequentially passed through the first fastening hole 420 and the second fastening hole 260, so that the cover body 400 is fixedly installed in the installation slot 240, and the second wire hole 230 and the grounding portion 220 as well as the ground wire passing from the second wire hole 230 to the grounding portion 220 are shielded. This structure can position and install the cover body 400, and makes the installation of the cover body 400 simpler and more convenient. At the same time, it can ensure that the ground wire is limited to the bottom of the cover body 400, avoiding the ground wire being directly exposed outside the body 100, thereby protecting the ground wire, improving the reliability of the grounding of the ground wire, and thereby improving the safety of the range hood.

[0050] It is understandable that the first fastening hole 420 and the second fastening hole 260 can be threaded holes. During installation, the cover body 400 can be fixed to the installation groove 240 by directly selecting suitable screws or bolts. The structure is simple and the materials are easy to obtain.

[0051] In some embodiments, a flexible sleeve is installed on the periphery of the first wire passing hole 320 and the periphery of the second wire passing hole 230 .

[0052] In the above structure, the provision of the flexible sleeve can protect the ground wire, preventing the ground wire from being scratched or cut due to the sharp edge of the first wire hole 320 or the second wire hole 230, thereby affecting the electrical performance of the ground wire.

[0053] It is understandable that the flexible sleeve may specifically be an oil-proof rubber ring, a silicone sleeve, etc., and the present invention does not make any specific limitation on this.

[0054] Reference Figures 1 to 10 In some embodiments, the periphery of the mounting opening has an outwardly folded edge 330 , and the folded edge 330 overlaps the periphery of the mounting hole 210 .

[0055] In the above structure, by setting an outward folded edge 330 on the periphery of the installation opening, the box body 300 is placed in the installation hole 210 of the top plate 200 during installation until the folded edge 330 overlaps the periphery of the installation hole 210. The structure is simple and makes the installation of the box body 300 simpler and more convenient.

[0056] Reference Figures 1 to 10 In some embodiments, at least one snap-in portion 350 is provided on the outer peripheral wall of the box body 300 . The snap-in portion 350 is located below the folded edge 330 and is spaced apart from the folded edge 330 to form a snap-in groove 360 ​​. The edge of the mounting hole 210 is snap-into the snap-in groove 360 ​​.

[0057] In the above structure, during installation, the box body 300 is placed into the mounting hole 210 of the top plate 200 from top to bottom until the edge of the mounting hole 210 is inserted into the snap-in groove 360 ​​between the snap-in portion 350 and the folded edge 330 of the box body 300. This can make the installation of the box body 300 more secure and stable, and avoid looseness between the box body 300 and the top plate 200 due to shaking or vibration when the range hood is working.

[0058] It is understandable that, referring to Figures 8 to 10 There are four clamping parts 350, two of which are distributed on the two opposite outer walls of the box body 300, so that the box body 300 can be more balanced in force during installation, and the box body 300 can be more conveniently installed in the installation hole 210 of the top plate 200. The utility model does not specifically limit the number and position of the clamping parts 350, which can be selected according to actual conditions.

[0059] It is understandable that, referring to Figures 1 to 10In some embodiments, a mounting column 370 for mounting electrical components such as a power board is provided in the mounting cavity of the box body 300, thereby facilitating the installation and positioning of electrical components such as the power board. In addition, the box body 300 is also provided with at least one reinforcing rib 340, thereby reinforcing the structural strength of the box body 300. Specifically, the reinforcing rib 340 can be provided at the folded edge 330 of the box body 300, the outer side wall of the box body 300, etc., and the utility model does not make specific limitations on this.

[0060] Reference Figures 1 to 10 In some embodiments, the clamping portion 350 is provided with a guide surface 351 , which is connected to the outer peripheral wall of the box body 300 and extends outward in a bottom-to-top direction.

[0061] In the above structure, the setting of the guide surface 351 can facilitate the installation of the box body 300 into the installation hole 210 of the top plate 200. Specifically, during installation, the box body 300 is placed into the installation hole 210 of the top plate 200 from top to bottom. During this process, the periphery of the installation hole 210 abuts against the guide surface 351 and moves relative to the box body 300 along the guide surface 351 until the edge of the installation hole 210 is inserted into the clamping groove 360 ​​between the clamping portion 350 and the folding edge 330 of the box body 300. This structure can guide the installation of the box body 300, making the installation of the box body 300 simpler and more convenient.

[0062] It is understandable that, referring to Figures 1 to 10 The guide surface 351 can be an inclined plane extending outward from bottom to top. Of course, in addition to this, the guide surface 351 can also be an arc-shaped curved surface inclined outward from bottom to top, and the present invention does not make specific limitations on this.

[0063] Reference Figures 1 to 7 In some embodiments, the cover body 400 is installed on the top plate 200 , and the folded edge 330 is sandwiched between the cover body 400 and the top plate 200 .

[0064] In the above structure, by sandwiching the folded edge 330 between the cover body 400 and the top plate 200, the installation stability of the box body 300 can be further enhanced, so that the installation of the box body 300 is more firm and stable.

[0065] Reference Figures 1 to 7 The second wire-passing hole 230 is an open slot opened at the edge of the mounting hole 210 , and the folded edge 330 can cover the opening of the open slot.

[0066] In the above structure, the second wire passing hole 230 is set as an open groove located at the edge of the mounting hole 210, so that the processing and opening of the second wire passing hole 230 is more convenient. By covering the opening of the open groove with the folded edge 330, the ground wire can be confined inside the second wire passing hole 230, and the ground wire is limited, making the installation of the ground wire more stable.

[0067] Reference Figures 1 to 7 In some embodiments, the edge of the second wire hole 230 is provided with a flange.

[0068] In the above structure, the flange setting can protect the ground wire and prevent the ground wire from being scratched or cut due to the periphery of the first wire hole 320 or the periphery of the second wire hole 230 being too sharp, thereby affecting the electrical performance of the ground wire.

[0069] It is understandable that, in some embodiments, the periphery of the first wire hole 320 may also be provided with a flange, thereby protecting the ground wire and preventing the ground wire from being scratched or cut due to the periphery of the first wire hole 320 or the periphery of the second wire hole 230 being too sharp, thereby affecting the electrical performance of the ground wire. It should be noted that, in some embodiments, only the edge of the second wire hole 230 may be provided with a flange, or only the periphery of the first wire hole 320 may be provided with a flange, or both the edge of the second wire hole 230 and the periphery of the first wire hole 320 may be provided with a flange, and the utility model does not make specific limitations on this.

[0070] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
