[0002] Range hoods are essential appliances for people to absorb oil fumes during daily cooking. Due to domestic cooking habits, the amount of oil fumes is large, and the requirements for oil fume extraction effects have become increasingly higher in recent years. Range hoods with smoke baffles are widely loved by people because their smoke baffles can greatly improve the oil absorption effect of range hoods.

[0003] For example, the Chinese utility model patent "A Range Hood" with application number 202223464845.5 (authorization announcement number CN219222559U) discloses a range hood structure with a smoke baffle. However, for this type of range hood, the lamps responsible for lighting are generally installed on the side or bottom of the cavity, and the lamps are usually hidden inside the smoke baffle. When the range hood is in the off state, the smoke baffle must be opened to turn on the light. However, users generally need to clean or prepare before cooking. For users with insufficient lighting in the cooking area, they hope to turn on the light without opening the smoke baffle to avoid touching the smoke baffle when operating on the kitchen countertop. At the same time, it also reduces the sense of oppression when the smoke baffle is opened. Therefore, it is difficult for such products to meet the actual needs of the aforementioned users.

The lamp body 4 is installed in the groove 3b, and the conductive column 41 passes through the oil collecting chamber 3a from bottom to top and is connected to the conductive plate assembly 5 arranged at the bottom of the smoke collecting hood 1.

[0029] Secondly, in order to optimize the overall structure of the lamp body 4 so that it can be better installed in the groove 3b of the oil cup 3, refer to Figures 4 to 6 As shown, in this embodiment, the lamp body 4 includes a PCB board 4a and a light-transmitting lampshade board 4b, the PCB board 4a is arranged in the groove 3b, the conductive column 41 is connected to the PCB board 4a, the PCB board 4a is provided with a lamp bead 4a1 for emitting light, and the lampshade board 4b covers the opening of the groove 3b to make the groove 3b closed.

[0030] At the same time, in order to reduce the height of the groove 3b so that it can better compress the space, thereby maximizing the oil collecting cavity 3a of the oil cup 3, refer to Figures 4 to 6As shown, the PCB board 4a in this embodiment is arranged on the side wall of the groove 3b, and a diffusion plate 4c is also arranged in the groove 3b. The light source emitted by the lamp bead 4a1 is diffused by the diffusion plate 4c and then emitted to the outside of the groove 3b through the lampshade plate 4b.

[0031] In addition, in order to optimize the overall structure of the conductive plate assembly 5 so that it can be better installed at the bottom of the smoke hood 1, refer to Figure 7 and Figure 8 As shown, in this embodiment, the conductive plate assembly 5 includes a conductive plate 5a installed at the bottom of the smoke hood 1, and a conductive sheet 5a1 is formed on the conductive plate 5a. The conductive sheet 5a1 is elastic and is tilted toward the insertion direction of the oil cup 3 when it is installed. When the oil cup 3 is installed, the top of the conductive column 41 can support the conductive sheet 5a1 to make the lamp body 4 conductive.

[0032] In addition, in order to prevent oil and water from flowing into the conductive plate assembly 5 and affecting the use of the lamp body 4 during the use of the range hood, Figure 5 and Figure 7 As shown, the conductive plate assembly 5 in this embodiment also includes a first insulating plate 5b arranged between the conductive plate 5a and the smoke hood 1, and the first insulating plate 5b is also provided with a circle of flange 5b1 folded downward, and the inner side wall of the flange 5b1 and the outer edge of the conductive plate 5a form a groove 5b2, and the first insulating plate 5b and the conductive plate 5a are both provided with mounting holes 5b3 for fasteners 5c to pass through from bottom to top.

[0033] In this embodiment, in order to optimize the structure of the conductive plate assembly 5 so that it can be more conveniently connected to the fastener 5c, refer to Figure 4 and Figure 5 As shown, the conductive plate assembly 5 in this embodiment further includes a second insulating plate 5d disposed above the first insulating plate 5b and located inside the smoke collecting hood 1, and the second insulating plate 5d is provided with a threaded hole 5d1 for threaded connection of a fastener.

[0034] In this embodiment, in order to separate the positive and negative electrodes of the lamp body 4 so that the lamp body 4 can be safer and more reliable in daily use, Figure 2 and Figure 3 As shown, in this embodiment, two conductive plate assemblies 5 are provided, and the two conductive plate assemblies 5 are spaced apart at the bottom of the smoke hood 1. Correspondingly, two conductive columns 41 are also provided, and the two conductive columns 41 are spaced apart and connected to the lamp body 4 and correspond to the conductive plate assemblies 5 adapted thereto.

[0035] It needs to be explained here that the conductive plates 5a of the two conductive plate assemblies 5 are respectively electrically connected to the positive and negative wires built into the smoke hood, and are generally powered by 12V DC. Since the positive and negative poles are separated, they are themselves at a safe extra-low voltage and are far apart, so there will be no short circuit even if they are soaked in water during cleaning.

[0036] refer to Figure 2 and Figure 3 As shown, in order to better realize the detachable setting between the oil cup 3 and the smoke hood 1, in the present embodiment, a transversely arranged slot 1a is provided at the bottom of the smoke hood 1, and a plug plate 3c adapted to the slot 1a is formed on the oil cup 3, so that the oil cup 3 can be detachably installed on the smoke hood 1 through the detachable plug-in between the slot 1a and the plug plate 3c.

When the smoke baffle 2 on the smoke hood 1 is closed, the lamp body 4 will be exposed at the bottom of the oil cup 3. A conductive column 41 exposed at the top of the oil cup 3 is connected to the lamp body 4, and a conductive plate assembly 5 that can adapt to the conductive column 41 is provided on the smoke hood 1. Thus, when the oil cup 3 is installed, the conductive column 41 can touch the conductive plate assembly 5 to turn on the lamp body 4, thereby achieving the purpose of external lighting without opening the smoke baffle 2. This reduces the disadvantage of the prior art that the smoke baffle 2 must be opened before turning on the light, avoids the danger caused by the user touching the smoke baffle 2 when operating on the kitchen countertop, and also reduces the sense of oppression brought by the smoke baffle 2 being opened, thereby improving the user's experience. In addition, since the oil cup 3 is the lowest point of the product, the lamp body 4 is arranged at the bottom of the oil cup 3 so that it is closer to the space that needs to be illuminated at the lower end, and the brightness of the bottom stove area can be improved under the same power. Another point is that since the oil cup 3 and the lamp body 4 adopt an integrated design, it also has the characteristics of fewer parts and convenient cleaning and dumping.
