[0035] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:
[0036] Please also read Figures 1 to 7 The utility model provides an oil guide structure. Specifically, the oil guide structure is used for a range hood. The oil guide structure comprises a shell 1, an inner bellows 2, an oil guide assembly 3 and an oil cup 4.
[0037] In this embodiment, please refer to Figure 1 and Figure 4 The housing 1 has a mounting chamber a and an oil guide chamber b. The mounting chamber a is provided with an air inlet 111, and the bottom of the oil guide chamber b is provided with an oil outlet 121.
[0038] The inner bellows 2 is arranged in the installation cavity a, the air inlet 111 is connected to the inner bellows 2, and an oil guide hole 21 connected to the oil guide cavity b is arranged on the inner bellows 2. When the user uses the hood with the oil guide structure, the user inhales the oil smoke through the air inlet 111 of the housing 1, and the oil smoke then enters the inner bellows 2 in the installation cavity a. When oil condenses in the inner bellows 2, the oil enters the oil guide cavity b through the oil guide hole 21.
[0039] The oil guide assembly 3 is arranged in the oil guide cavity b, and the oil guide assembly 3 guides the oil flowing out of the oil guide hole 21 to the bottom of the oil guide cavity b. When using the range hood with the oil guide structure, the user uses the oil guide assembly 3 to guide the oil flowing out of the oil guide hole 21 to the bottom of the oil guide cavity b, so that the oil flows out through the oil outlet 121 at the bottom of the oil guide cavity b. The oil guide assembly 3 can guide the oil condensed inside the range hood to prevent the oil from flowing along the inner wall of the oil guide cavity b, reduce the oil from entering the internal gaps of the various structures of the range hood, and avoid the failure of the various structures of the range hood, thereby improving the service life of the range hood.
[0040] The oil cup 4 is connected to the bottom of the housing 1, and the oil receiving port of the oil cup 4 is aligned with the oil outlet 121, and is used to receive the oil flowing out of the oil outlet 121. When the user uses the range hood with an oil guide structure, the oil flowing out of the oil outlet 121 at the bottom of the oil guide cavity b drips into the oil cup 4, and the user can collect the oil more conveniently through the oil cup 4, so that the user only needs to clean the oil in the oil cup 4, thereby reducing the difficulty of cleaning the range hood.
[0041] The utility model discloses an oil guiding structure, through the arrangement of the shell body 1, the inner bellows 2, the oil guiding assembly 3 and the oil cup 4, when the user uses the range hood, the oil smoke enters the inner bellows 2 in the installation cavity a through the air inlet 111 of the shell body 1, when the oil liquid condenses in the inner bellows 2, the oil liquid enters the oil guiding cavity b through the oil guiding hole 21, and the oil guiding assembly 3 is used to guide the oil liquid flowing out of the oil guiding hole 21 to the bottom of the oil guiding cavity b, so that the oil liquid flows out through the oil outlet 121 at the bottom of the oil guiding cavity b, and then flows into the oil cup 4 for collection; the oil guiding assembly 3 is used to guide the oil liquid condensed inside the range hood, so as to avoid the oil liquid flowing along the inner wall of the oil guiding cavity b, reduce the oil liquid entering the internal gaps of the various structures of the range hood, thereby reducing the difficulty of cleaning the range hood; at the same time, it can also improve the service life of the range hood.

Specifically, there are two first oil guide grooves 31, and the two first oil guide grooves 31 are arranged in an inverted "eight" shape relative to each other. This facilitates the user to collect and guide the oil in the process of using the range hood, and the collected oil can better flow out through the bottom of the back plate 12, thereby reducing the oil from entering the internal gaps of various structures of the range hood.
[0045] Based on the above examples, please refer to Figure 3 , Figure 4 and Figure 6 In other embodiments, the oil guide assembly 3 further includes a second oil guide groove 32, which is disposed at the oil outlet end of the first oil guide groove 31, and the downward projection of the oil outlet end of the first oil guide groove 31 falls into the second oil guide groove 32, and the downward projection of the oil outlet end of the second oil guide groove 32 falls into the bottom of the back plate 12, and the first oil guide groove 31 guides the oil into the second oil guide groove 32, and the second oil guide groove 32 guides the oil into the bottom of the back plate 12 and drips into the oil cup 4 through the oil outlet 121 at the bottom of the back plate 12. When the user uses the range hood, the oil in the first oil guide groove 31 flows into the second oil guide groove 32, and the oil in the second oil guide groove 32 is then guided into the bottom of the back plate 12, so as to prevent the oil in the first oil guide groove 31 from flowing on the front plate 14.
[0046] Based on the above examples, please refer to Figure 4 and Figure 5In other embodiments, the rear edge of the air suction panel 11 extends downward with an extension portion 112, and the lower edge of the extension portion 112 is connected to an oil collecting box 113, which is aligned with the oil guide hole 21, and is provided with an oil leakage hole 1131 aligned with the oil inlet end of the oil guide assembly 35.
