DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1-4As shown, the oil cup ejection device provided by the embodiment of the present invention includes: an oil cup 100, the oil cup 100 is installed below the smoke guide plate 200, the oil cup 100 includes a cup wall, an air inlet 110 and an air outlet 120 are provided on the cup wall, and an air path connecting the air inlet 110 and the air outlet 120 is provided inside the cup wall, the air inlet 110 of the oil cup 100 is connected to the fan 400 through the air guide channel 300, and the air flow generated by the fan 400 flows through the air guide channel 300 and the air path inside the oil cup 100 in turn, and then flows out from the air outlet 120 and forms an ejection airflow, which blows onto the lower surface of the smoke guide plate 200. The ejection airflow can carry the smoke along the extension direction of the smoke guide plate 200 to the gap between the smoke guide plate 200 and the smoke collecting hood.

[0032] Unlike existing ejection mechanisms, the oil cup ejection device provided in this embodiment of the present invention incorporates the ejection airflow path within the oil cup 100. This eliminates the need for additional structural components. Instead, the ejection airflow is generated by the air outlet 120 on the oil cup 100, directing smoke toward the smoke guide plate 200 above it. The oil cup 100, a structural component that receives oil stains from the smoke guide plate 200, is already present in existing technology, so the oil cup ejection device does not occupy additional space.

[0033] like Figure 5 As shown, in one embodiment, there can be multiple air outlets 120, each of which has different opening directions. The multiple air outlets 120 can be arranged around the circumference of the oil cup 100, and can spray the smoke guide plate 200 from multiple points.

[0034] like Figure 6 As shown, in another embodiment, the air outlet 120 is annular, and the annular air outlet 120 is arranged around the circumference of the oil cup 100. The annular air outlet 120 can form a continuous and uniform air curtain around the circumference of the oil cup 100, thereby generating a continuous and uniform induced airflow on the smoke guide plate 200.

[0035] Specifically, the cup wall includes an inner wall 130 and an outer wall 140 spaced apart from each other. The inner wall 130 is used to collect oil stains. The gap between the inner wall 130 and the outer wall 140 forms the air path, and the gap between the edges of the inner wall 130 and the outer wall 140 forms the annular air outlet 120.

[0036] like Figure 2 As shown, the gap inside the double-layer oil cup 100 forms an air path, and the gap between the edge of the inner wall 130 and the edge of the outer wall 140 can form an annular air outlet 120, thereby achieving continuous and uniform spraying in the circumferential direction of the oil cup 100.

[0037] In other feasible solutions, multiple partition structures can be provided circumferentially between the inner wall 130 and the outer wall 140 to separate the annular opening into multiple air outlets 120, thereby achieving circumferential point injection. Reducing the cross-sectional area of the air outlets 120 increases the injection pressure and improves the oil fume drainage effect. The partition structures can also serve to connect the inner wall 130 and the outer wall 140.

[0038] like Figure 2 and Figure 3 As shown, along the depth direction of the oil cup 100 , from bottom to top, the air outlet 120 is inclined toward the outside of the oil cup 100 .

[0039] To prevent the air outlet 120 from directly blowing into the smoke guide plate 200, the smoke guide plate 200 can be a flat plate or a curved plate. If the smoke guide plate 200 is a curved plate, the surface of the smoke guide plate facing the oil cup is a curved surface that convexly faces the oil cup. The air outlet 120 can be oriented parallel to the cross-section of the smoke guide plate 200 to minimize airflow resistance and achieve a better airflow effect.

[0040] like Figure 3 As shown, the oil cup ejection device further includes a fan 400 and an air guide duct 300. The air guide duct 300 is connected to the fan 400 and the air inlet 110, respectively, so that the airflow generated by the fan 400 enters the air path of the oil cup 100. The fan 400 and the air guide duct 300 can be fixed inside the range hood body, and the range hood housing is provided with ventilation holes corresponding to the fan 400.

[0041] The oil cup ejection device also includes a smoke guide plate 200, the oil cup 100 is arranged below the smoke guide plate 200, and the air outlet 120 faces the smoke guide plate 200; the smoke guide plate 200 is provided with a first drainage tube 210 that passes through the upper and lower surfaces of the smoke guide plate 200, the air inlet 110 is connected to the lower end opening of the first drainage tube 210, and the upper end opening of the first drainage tube 210 is connected to the air guide channel 300.

[0042] The fan 400 and air guide channel 300 are located above the smoke guide plate 200, while the oil cup 100 is located below it. A first air guide tube 210 on the smoke guide plate 200 connects the smoke guide channel to the air inlet 110 of the oil cup 100. In the oil cup ejection device, only the oil cup 100 is displaced below the smoke guide plate 200, resulting in a simpler appearance and easier cleaning; only the oil cup 100 needs to be cleaned regularly.

[0043] The oil cup 100 is provided with a connecting pipe 150 connected to the cup wall, one end opening of the connecting pipe 150 is connected to the air path, and the other end opening of the connecting pipe 150 forms an air inlet 110; the connecting pipe 150 is detachably connected to the lower end opening of the first drainage pipe 210, so that the air flow passes through the first drainage pipe 210 and the connecting pipe 150 in sequence and enters the air path.

[0044] The connecting tube 150 can be located inside the oil cup 100 and can be integrally formed with the inner wall 130, thereby connecting the connecting tube 150 to the air path. The connecting tube 150 connects the air path to the first drainage tube 210 and can be connected to the first drainage tube 210 using a plug-in connection. Removing the oil cup 100 from the smoke deflector plate 200 facilitates the removal of oil stains and cleaning.

[0045] like Figure 4 As shown, the connecting tube 150 can be inserted into the inner side of the first drainage tube 210. In order to increase the sealing and connection strength between the two, a first annular sealing ring 510 can be provided on the inner wall 130 of the first drainage tube 210. The material can be a flexible material such as rubber. A first limiting groove 151 corresponding to the first annular sealing ring 510 is provided on the outer wall 140 of the connecting tube 150. When the first drainage tube 210 and the connecting tube 150 are plugged in, the first annular sealing ring 510 enters the first limiting groove 151. On the one hand, the first annular sealing ring 510 can increase the sealing between the first drainage tube 210 and the connecting tube 150. On the other hand, the first limiting groove 151 and the first annular sealing ring 510 can prevent the first drainage tube 210 and the connecting tube 150 from separating. When the user pulls the oil cup 100 outward with greater force, the elastic force of the first annular sealing ring 510 can be overcome, causing the first annular sealing ring 510 to deform, thereby removing the oil cup 100 from the first drainage tube 210 .

[0046] The air guide channel 300 includes a second air guide tube 310, which is detachably connected to the upper end of the first air guide tube 210. This allows airflow to pass through the second air guide tube 310 and the first air guide tube 210 before entering the air path within the oil cup 100. Because the first and second air guide tubes 210 and 310 are detachable, the smoke guide plate 200 can be removed from the range hood body, making it easier to clean.

[0047] like Figure 4 As shown, the smoke guide plate 200 is provided with an oil leakage hole connecting the upper and lower walls thereof, and the oil cup 100 is located below the oil leakage hole. The oil cup 100 can collect the oil accumulated on the inner side of the smoke guide plate 200 .

[0048] like Figure 4As shown, the first drainage tube 210 and the second drainage tube 310 can be connected in a plug-in manner. After the first drainage tube 210 and the second drainage tube 310 are connected, the gas generated by the fan 400 can enter the gas path of the oil cup 100. The second drainage tube 310 can be plugged into the inner side of the first drainage tube 210. In order to increase the sealing and connection strength between the two, a second annular sealing ring 520 can be provided on the inner wall 130 of the first drainage tube 210. The material can be a flexible material such as rubber. A second limiting groove corresponding to the second annular sealing ring 520 is provided on the outer wall 140 of the second drainage tube 310. When the first drainage tube 210 and the second drainage tube 310 are plugged together, the second annular sealing ring 520 enters the second limiting groove. On the one hand, the second annular sealing ring 520 can improve the sealing between the first drainage tube 210 and the second drainage tube 310. On the other hand, the second limiting groove and the second annular sealing ring 520 can prevent the first drainage tube 210 and the second drainage tube 310 from separating. When the user pulls the first drainage tube 210 outward with greater force, the elastic force of the second annular sealing ring 520 can be overcome, causing the second annular sealing ring 520 to deform, thereby separating the first drainage tube 210 and the second drainage tube 310.

[0049] The range hood provided by the embodiment of the present invention includes the above-mentioned range hood. Since the range hood provided by the embodiment of the present invention adopts the above-mentioned oil cup ejection device, the range hood provided by the embodiment of the present invention also has the advantages of the oil cup ejection device.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
