[0024] Reference Figure 1-4 :

[0025] The utility model provides an oil fume purification and fresh air integrated fume hood and an oil fume removal system composed thereof;

[0026] The oil fume removal system includes a negative pressure generator, and the negative pressure generator is connected to an oil fume purification and fresh air integrated hood;

[0027] In addition, the oil fume purification and fresh air integrated fume hood includes a smoke extraction hood 1 and a waste oil recovery hood 2. Two L-shaped hanging plates 3 are fixed to the bottom of the smoke extraction hood 1. Side plates 4 are fixed on both sides of the top of the waste oil recovery hood 2. The side plates 4 can be embedded in the L-shaped hanging plates 3. An inner concave plate 5 is fixed inside the waste oil recovery hood 2. A cylindrical rod 6 is slidably connected inside the waste oil recovery hood 2 and the inner concave plate 5. An outer side of one end of the cylindrical rod 6 is coated with a marking layer 7. A control component for controlling the movement of the cylindrical rod 6 is arranged in the waste oil recovery hood 2.

[0028] It should be added that the negative pressure generator is set as an air compressor, which is connected to the oil fume purification and fresh air integrated hood through a pipe. Under the action of the negative pressure generator, a negative pressure chamber can be formed in the oil fume purification and fresh air integrated hood, so that the oil fume in the kitchen can be sucked into the oil fume purification and fresh air integrated hood.

[0029] When in use, the oil fume purification and fresh air integrated fume hood consists of a fume extraction hood 1 and a waste oil recovery hood 2. After the negative pressure generator sucks the oil fume into the fume extraction hood 1, it is filtered in an oil fume filtering device (existing technology, not shown in this device) in the fume extraction hood 1. The waste oil obtained after filtration will flow through the fume extraction hood 1 to the waste oil recovery hood 2 for recovery. When the waste oil in the waste oil recovery hood 2 collects to a certain volume, the waste oil recovery hood 2 is moved so that the side plate 4 is removed from the L-shaped hanging plate 3, and the waste oil recovery hood 2 can be removed, thereby pouring out the waste oil in the waste oil recovery hood 2.

[0030] Specifically, a slot 8 is provided in the waste oil recovery cover 2, and the cylindrical rod 6 is slidably fitted in the slot 8. A spring 10 is sleeved on the outside of the cylindrical rod 6, and an annular sleeve 9 is fixed on the outside of the cylindrical rod 6. One end of the spring 10 is against the annular sleeve 9, and the other end of the spring 10 is against the inner wall of the waste oil recovery cover 2. When the spring 10 is in a normal state, the identification layer 7 is located in the slot 8. It should be noted that the identification layer 7 can be painted in conspicuous colors such as red and yellow, which can attract users very intuitively.

[0031] In addition, the control component includes a floating plate 12 arranged in the waste oil recovery cover 2, a pressurized ball 11 is fixed to the end of the cylindrical rod 6 away from the identification layer 7, and an extrusion block 13 for extruding the pressurized ball 11 is fixed to the top of the floating plate 12. The part of the extrusion block 13 close to the pressurized ball 11 is an arc-shaped surface. Two travel grooves 15 are provided on the inner walls on both sides of the waste oil recovery cover 2, and two connecting plates 14 are fixed on both sides of the floating plate 12, and the connecting plates 14 are slidably fitted in the travel grooves 15.

[0032] During use, when the waste oil in the waste oil recovery cover 2 gradually increases, the floating plate 12 will be driven to move upward. When the floating plate 12 moves upward, it drives the squeezing block 13 to squeeze the pressurized ball 11, thereby driving the pressurized ball 11 to move. When the pressurized ball 11 moves, it drives the cylindrical rod 6 to move. When the identification layer 7 on the cylindrical rod 6 is partially moved out of the slot 8, the user is reminded that the waste oil in the waste oil recovery cover 2 is about to be full. At this time, the waste oil recovery cover 2 needs to be removed and the waste oil inside it needs to be poured out. After the waste oil in the waste oil recovery cover 2 is poured out, the floating plate 12 is moved downward. At this time, the identification layer 7 is driven to move into the slot 8 under the rebound force of the spring 10.

[0033] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
