Detailed Implementation
[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0028] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.
[0029] like Figures 1 to 7As shown, a range hood according to an embodiment of the present invention includes: a range hood housing 100 having a smoke collection chamber; a fixing bracket 200 detachably installed on the range hood housing 100 by bolt connection. It is conceivable that the fixing bracket 200 can also be fixedly installed on the range hood housing by welding or gluing, which will not be described in detail here; the fixing bracket 200 is detachably connected to an oil guide plate 300, and the oil guide plate 300 is located at the smoke inlet of the smoke collection chamber; the fixing bracket 200 is also detachably connected to an oil cup 400, which is located below the oil guide plate 300. The oil droplets condensed inside the range hood will fall onto the oil guide plate 300, and then fall into the oil cup 400 below the oil guide plate 300, thus completing the collection of oil droplets. The fixed bracket 200 is detachably connected to both the oil guide plate 300 and the oil cup 400. The range hood housing 100 does not need to have a groove for the oil cup to be inserted, which reduces the number of parts required when installing the oil guide plate 300 and the oil cup 400, thereby simplifying the installation process and reducing installation time.
[0030] Reference Figures 2 to 4 In some embodiments, the lower end of the fixed bracket 200 is provided with two snap-fit mechanisms 210, and the oil guide plate 300 is provided with corresponding snap-fit holes 310 adapted to the two snap-fit mechanisms 210. The snap-fit mechanisms 210 pass through the snap-fit holes 310, and the oil guide plate 300 snaps into the snap-fit mechanisms 210. When producing the oil guide plate 300, only holes need to be punched on the oil guide plate 300, which simplifies the manufacturing process and improves the production efficiency of the oil guide plate 300 to a certain extent. In actual operation, the oil guide plate 300 is lifted, and the two snap-fit holes 310 are aligned with the two snap-fit mechanisms 210 respectively. By pushing the oil guide plate 300 upward, the snap-fit between the oil guide plate 300 and the snap-fit mechanism 210 can be completed, thereby realizing the detachable connection between the oil guide plate 300 and the fixed bracket 200. The detachable connection between the oil guide plate 300 and the fixed bracket 200 using the above structure has the advantages of simple and easy installation, short time consumption, and strong practicality.
[0031] It should be noted that, provided the strength requirements are met, the lower end of the fixed bracket 200 may only have one snap-fit mechanism 210, in which case only one snap-fit hole 310 is required; if the service life of the snap-fit mechanism 210 is to be increased, the number of snap-fit mechanisms 210 may be increased to three or more, and the number of snap-fit holes 310 shall also be increased accordingly. The number of snap-fit mechanisms 210 and snap-fit holes 310 may be determined by actual needs, and will not be described in detail here.
[0032] Reference Figure 3 , Figure 4 and Figure 6In some embodiments, the snap-fit mechanism 210 includes two spaced-apart spring pieces 230, and each spring piece 230 has a stepped portion 220 on its outer side wall. When the two spring pieces 230 pass through the snap-fit hole 310, the stepped portion 220 snaps into the edge of the snap-fit hole 310. The distance between the outer side walls of the two spring pieces 230 is less than or equal to the width of the snap-fit hole 310, ensuring that the snap-fit mechanism 210 can snap into the snap-fit hole 310. However, the distance from the stepped portion 220 of one spring piece 230 to the outer side wall of the other spring piece 230 is greater than the width of the snap-fit hole 310, and the stepped portion 220 snaps into the edge of the snap-fit hole 310. This ensures that during actual use, the snap-fit mechanism 210 will not easily disengage from the snap-fit hole 310, causing the oil guide plate 300 to fall off. The snap-fit mechanism 210, composed of two spaced-apart spring pieces 230, has a simple structure, is easy to manufacture, and is highly practical.
[0033] If the strength requirement is met, only one spring piece 230 may have a stepped portion 220 on its outer wall that engages with the edge of the snap-fit hole 310. If the distance between the stepped portion 220 of one spring piece 230 and the other spring piece 230 is greater than the width of the snap-fit hole 310, the snap-fit effect can still be achieved. The specific number of stepped portions 220 will not be detailed here.
[0034] It should be noted that, in addition to the aforementioned structure for engaging with the oil guide plate 300, in some embodiments, the engaging mechanism 210 may also include a cuboid component and a connecting post. The connecting post is vertically oriented and its upper end is fixedly connected to the fixed bracket 200. The cuboid component is horizontally oriented and connected to the lower end of the connecting post by a screw, and the cuboid component can rotate around the axis of the screw. The length of the cuboid component is greater than the width of the engaging hole 310, and the length of the cuboid component is less than the length of the engaging hole 310. The cross-sectional area of the connecting post is smaller than the area of the engaging hole 310. When installing the oil guide plate 300, the cuboid component and the connecting post are passed through the engaging hole 310, and the cuboid component is twisted 90 degrees around the axis of the screw, so that both ends of the cuboid component engage with the edges of the engaging hole 310, thereby achieving a detachable connection between the oil guide plate 300 and the engaging mechanism 210.
[0035] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7In some embodiments, a pin 410 is provided at the upper end of the oil cup 400, and a insertion channel 240 is provided between the two spring pieces 230. The pin 410 is inserted into the insertion channel 240, and the pin 410 and the insertion channel 240 are interference-fitted. The size of the pin 410 is larger than the size of the insertion channel 240. When the pin is inserted into the insertion channel 240, the two spring pieces 230 will deform in a direction away from each other under the action of the pin 410. The deformed two spring pieces 230 have elastic force, which will clamp the pin 410 and prevent the pin 410 from easily disengaging from the insertion channel 240, thereby causing the oil cup 400 to disengage from the locking mechanism 210, resulting in waste oil splashing out and affecting the user experience. The outer walls of the deformed two spring pieces 230 can also abut against the inner wall of the locking hole 310 to further fix the oil guide plate 300.
[0036] It should be noted that oil droplets can flow directly from the snap-fit hole 310 into the oil cup 400 along the spring piece 230, thus achieving oil droplet collection.
[0037] Reference Figure 6 In some embodiments, the inner sidewalls of the two spring pieces 230 are provided with through grooves 231, and the gap between the through grooves 231 and the two spring pieces 230 forms an insertion channel 240. The pin 410 can be a cylinder, cuboid, frustum, or other shape. The shape of the insertion channel 240 is adapted to the pin 410, and the shape of the pin 410 can be flexibly selected according to the actual situation. By inserting the pin 410 provided at the upper end of the oil cup 400 into the insertion channel 240, the connection between the oil cup 400 and the snap-fit mechanism 210 can be quickly and conveniently achieved, reducing the time required for assembling and disassembling the oil cup 400.
[0038] It should be noted that only one spring piece 230 has a through groove 231 on its inner side wall, which can also form an insertion channel 240 with the gap between two spring pieces 230, so that the pin 410 can be inserted into the insertion channel 240. The number of through grooves 231 can be selected according to the actual situation, which will not be described in detail here.
[0039] Reference Figure 7 In some embodiments, to facilitate the insertion of the pin 410 into the insertion channel 240, the cross-sectional area of the end of the pin 410 facing the insertion channel 240 and initially inserted into the insertion channel 240 gradually increases along the length of the pin 410. When the pin 410 is inserted into the insertion channel 240, since the cross-sectional area of the end of the pin 410 initially inserted into the insertion channel 240 is smaller, a portion of the pin 410 can be easily inserted into the insertion channel 240. As the pin 410 is continuously pushed into the insertion channel 240, the cross-sectional area of the pin 410 gradually increases, and an interference fit occurs between the pin and the insertion channel 240.
[0040] Reference Figure 7In some embodiments, the oil cup 400 and the pin 410 are integrally formed. Manufacturing the oil cup 400 and the pin 410 as an integral structure can reduce the number of parts required when assembling the oil cup, thereby simplifying the installation process.
[0041] Reference Figure 2 and Figure 5 In some embodiments, one end of the oil guide plate 300 is provided with a rotating bracket 320 hinged to the range hood housing 100. The rotating bracket 320 is formed by bending one end of the oil guide plate 300. In the prior art, the rotating bracket 320, as a separate part, can be connected to the oil guide plate 300 by welding or screws. Welding pretreatment and welding processes are cumbersome, and post-weld grinding is required, resulting in low production efficiency of the oil guide plate 300. Screw connections increase the number of parts, leading to a longer installation time for the oil guide plate 300. In this embodiment of the invention, the oil guide plate 300 and the rotating bracket 320 are an integral structure, instead of the rotating bracket 320 being a separate part connected to the oil guide plate 300 by welding or other means. This effectively simplifies the production process and improves the production efficiency of the oil guide plate 300. By hinged to the range hood housing 100, the force exerted by the oil guide plate 300 on the fixed bracket 200 can be dispersed, improving the service life of both the fixed bracket 200 and the range hood housing 100.
[0042] Reference Figure 5 In some embodiments, one end of the oil guide plate 300 is provided with an outwardly extending connecting portion, and the free end 322 of the connecting portion is wound to form a rotating bracket 320. The connecting portion includes a fixed end 321 and a free end 322. The fixed end 321 is connected to the oil guide plate 300 as a whole, and the free end 322 is a flat plate structure. The free end 322 is bent into a cylindrical structure that is easy to rotate by a rolling process. The smoke hood housing 100 is provided with two hooks. The shape of the inner side of the hooks is adapted to the cylindrical structure. The oil guide plate 300 is swung in the two hooks of the cylindrical structure, and the cylindrical structure will rotate inside the hooks. Then, the snap-fit mechanism 210 is snapped into the snap-fit hole 310 to fix the oil guide plate 300. With the above installation method, the weight of the oil guide plate 300 is distributed from multiple points, and the structure is more stable.
[0043] It should be noted that the free end 322 can also be bent into a hook structure through a rolling process, and a rotating shaft that cooperates with the hook structure is provided at the lower end of the range hood housing 100. By hooking the hook structure onto the rotating shaft, the rotating bracket 320 and the range hood housing 100 are hinged.
[0044] Reference Figure 5In some embodiments, the oil guide plate 300 is provided with an oil collecting part 332, the horizontal height of which is lower than the horizontal height of other parts of the oil guide plate 300. The oil cup 400 is located below the oil collecting part 332, and the surface of the oil collecting part 332 is provided with an oil drain hole 333. The oil falling on the oil guide plate 300 will eventually collect on the oil collecting part 332 and fall into the oil cup 400 through the oil drain hole 333 on the surface of the oil collecting part 332, thus completing the oil collection.
[0045] It should be noted that the snap-fit hole 310 can also be an oil drain hole 333, that is, the snap-fit hole 310 can both snap into the snap-fit mechanism 210 and allow oil to drip from the snap-fit hole 310 into the oil cup 400.
[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
