[0027] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0028] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0030] An embodiment of this utility model provides an oil-proof lighting lamp for a range hood, such as... Figure 1-4 As shown, the device includes a housing 100, a light guide plate 200, and a light-emitting device 300. The top surface of the housing 100 has a receiving groove 101, within which the light-emitting device 300 and other accessories are fixed. The receiving groove 101 provides the necessary installation space. The light-emitting device 300 emits light, and the light guide plate 200 allows the light to pass through and also serves to uniformly distribute the light.

[0031] The top surface of the housing 100 is provided with a first annular groove 110 and a first protruding ring 120 surrounding the receiving groove 101. Both the first annular groove 110 and the first protruding ring 120 are annular and surround the opening of the receiving groove 101 on the top surface of the housing 100. The surface of the light guide plate 200 is provided with a second protruding ring 210 that matches the first annular groove 110 and a second annular groove 220 that matches the first protruding ring 120. The light guide plate 200 abuts against the top surface of the housing 100, with the second protruding ring 210 inserted into the first annular groove 110 and the first protruding ring 120 inserted into the second annular groove 220, presenting an alternating insertion state. The light guide plate 200 is connected to the housing 100 by ultrasonic welding. During ultrasonic welding, the light guide plate 200 and the top surface of the housing 100 will be bonded together, and the first convex ring 120 and the second convex ring 210 will be heat-fused, so that the first convex ring 120 can fill the second annular groove 220 and the second convex ring 210 can fill the first annular groove 110. The light guide plate 200 and the housing 100 can be tightly combined, which greatly improves the sealing performance and effectively seals the receiving groove 101. Oil stains are difficult to enter the interior of the lighting lamp, ensuring the lighting effect of the lighting lamp and improving the user experience.

[0032] In some embodiments, such as Figure 2-4 As shown, a first convex ring 120 is formed between the inner wall of the receiving groove 101 and the inner wall of the first annular groove 110. The convex ring is formed by utilizing the side wall of the groove, which simplifies the structure. The first annular groove 110 and the first convex ring 120 are adjacent to each other. The second convex ring 210 inserted into the first annular groove 110 can be adjacent to the first convex ring 120, which further improves the tightness of the connection between the light guide plate 200 and the housing 100.

[0033] In some embodiments, such as Figure 2-4 As shown, a third convex ring 230 is provided on the surface of the light guide plate 200. The third convex ring 230 can be located inside the second convex ring 210 or surround the second convex ring 210. A second annular groove 220 is formed between the second convex ring 210 and the third convex ring 230. The annular groove is formed by two convex rings, rather than directly slotting the surface of the light guide plate 200. After the second convex ring 210 is inserted into the first annular groove 110, the surface of the light guide plate 200 can be in close contact with the top surface of the housing 100.

[0034] Furthermore, the third convex ring 230 is located inside the second convex ring 210, and the third convex ring 230 is inserted into the receiving groove 101 and abuts against the inner wall of the receiving groove 101. After ultrasonic welding, the third convex ring 230 can be tightly combined with the inner wall of the receiving groove 101, which further improves the tightness of the combination between the light guide plate 200 and the housing 100, and further improves the sealing performance.

[0035] Furthermore, the receiving groove 101 includes a flared groove 102 located at its opening. The opening area of ​​the flared groove 102 is larger, which is equivalent to enlarging the opening of the receiving groove 101. The lower part of the receiving groove 101 forms a stepped structure at the connection with the flared groove 102. The third protruding ring 230 is inserted into the flared groove 102 and abuts against the inner wall of the flared groove 102. The flared groove 102 can accommodate the heat-fused third protruding ring 230, making it less likely for the heat-fused material to drip. At the same time, the welded third protruding ring 230 is equivalent to filling the flared groove 102, making the inner wall of the receiving groove 101 relatively flat and with less depression.

[0036] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, spring clips 410 are provided on both sides of the housing 100. The spring clips 410 can be used to snap and fix the entire lighting lamp into the corresponding mounting slot. After the lighting lamp is installed, it can be pulled outward to remove it. This structure facilitates the installation and removal of the lighting lamp.

[0037] Furthermore, a connecting plate 420 is fixed to the bottom of the housing 100, and both ends of the connecting plate 420 are connected to two spring pieces 410 respectively. The two spring pieces 410 are installed through the same connecting plate 420, which simplifies the installation structure.

[0038] The connecting plate 420 and the two spring clips 410 can be integrally molded, which facilitates overall manufacturing and also enhances the connection strength. The connecting plate 420 can be fixed to the bottom of the housing 100 by various methods such as screw fixing and adhesive fixing.

[0039] Furthermore, the bottom surface of the housing 100 is provided with a mounting groove, and the connecting plate 420 is embedded in the mounting groove. The mounting groove plays a positioning role for the connecting plate 420, restricting the connecting plate 420 from moving to both sides, and the connecting plate 420 can be stably installed in the mounting groove.

[0040] In some embodiments, such as Figure 3 As shown, a circuit board 310 is fixed inside the receiving groove 101, and the light-emitting device 300 includes LED beads fixed on the circuit board 310. The LED beads are directly fixed to the circuit board 310, which reduces wiring. Specifically, LED beads can be used, and the circuit board 310 can be fixed to the bottom wall of the receiving groove 101 by screws.

[0041] This utility model provides a range hood, including an oil-proof range hood light according to any of the above embodiments. Detailed descriptions of the oil-proof range hood light can be found in the above embodiments and will not be repeated here.

[0042] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art will understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined in the appended claims and their equivalents.
