[0028] In order to make the personnel in the technical field better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the technical solution range of the present application.

[0029] Embodiment one:

[0030] As shown in the drawings, the present embodiment provides an oil discharging system for a smoke machine, which comprises a smoke machine body 1 having an air inlet 11 and an oil cup 2 arranged at the bottom position of the smoke machine body 1, and further comprises: Figures 1 to 6 a smoke guide plate 3 movably arranged at the position of the air inlet 11;

[0031]

[0032] ​The oil net assembly 4 is hingedly connected to the smoke guide plate 3 at one end and slidably connected to the smoke machine body 1 at the other end;

[0033] The driving assembly is arranged on the smoke machine body 1, and the output end of the driving assembly is connected to the smoke guide plate 3 to drive the oil net assembly 4 to open and close the air inlet 11 through the smoke guide plate 3;

[0034] The first oil collecting member 6 is arranged on the inner side wall of the smoke guide plate 3 to collect oil on the inner wall of the smoke machine body 1;

[0035] The second oil collecting member 7 is arranged on the inner side wall of the smoke guide plate 3 below the first oil collecting member 6, and the oil collected on the first oil collecting member 6 flows through the second oil collecting member 7 and the oil net assembly 4 in sequence and then collects on the oil cup 2 through the action of the smoke guide plate 3, or the oil collected on the second oil collecting member 7 collects on the oil cup 2 through the oil net assembly 4.

[0036] In this embodiment, in order to increase the air inlet area and reduce the distance between the air inlet 11 and the oil fume, the oil net assembly 4 is flipped with the opening of the smoke guide plate 3, and then is retracted into the inner cavity of the smoke machine body 1 with the smoke guide plate 3 after the oil net assembly 4 is closed. Since the front side wall inside the smoke machine body 1 accumulates a large amount of oil, the first oil collecting member 6 collects oil on the front side wall of the smoke machine body 1. When the air inlet 11 is in a closed state, the oil on the first oil collecting member 6 flows through the second oil collecting member 7 and the oil net assembly 4 in sequence and then collects on the oil cup 2. When the air inlet 11 is in an open state, the oil collected on the second oil collecting member 7 collects on the oil cup 2 through the oil net assembly 4. The collection and flow direction of the oil inside the smoke machine body 1 are fully considered. In this way, the oil can be prevented from dripping on the cooking table, and the purpose of collecting oil is achieved. The structure is simple, and the oil inside the smoke machine body 1 can be effectively collected, so that the oil is prevented from dripping on the cooking table.

[0037] Further, the oil net assembly 4 includes a fixed support 41 and an oil net 42. A guide rail 12 is arranged in the smoke machine body 1. One end of the fixed support 41 is hingedly connected to the smoke guide plate 3, and the other end is slidably connected to the smoke machine body 1 through the guide rail 12. The oil net 42 is protruded on the fixed support 41. The outer side wall of the fixed support 41 extends upward to form a flange 43. The flange 43 and the oil net 42 cooperatively define a guide oil groove 44. The guide oil groove 44 is adapted to guide the oil on the first oil collecting member 6 or the second oil collecting member 7 to the oil cup 2. The structure is simple and reasonable, and the oil on the first oil collecting member 6 or the second oil collecting member 7 can be effectively guided to the oil cup 2.

[0038] Preferably, the fixed support 41 is provided with an oil guiding hole 45 at an end away from the smoke guide plate 3, and the oil guiding hole 45 is located inside the smoke machine body 1 so that the oil entering the oil guiding groove 44 flows into the oil cup 2 through the oil guiding hole 45. The structure is simple, and the oil entering the oil guiding groove 44 can flow into the oil cup 2 along the preset path.

[0039] Specifically, the fixed support 41 is provided with a convex edge 46 extending forward at an end close to the smoke guide plate 3, and the convex edge 46 extends into the second oil receiving member 7 to prevent the oil on the second oil receiving member 7 from overflowing outward. The structure is simple and compact, and the smoke guide plate 3 and the oil screen assembly 4 can be embedded with each other in any case, thereby effectively preventing the oil on the second oil receiving member 7 from overflowing outward.

[0040] Preferably, the transverse width of the fixed support 41 is greater than the transverse width of the smoke guide plate 3. The design is reasonable, and the smoke guide plate 3 can be within the range surrounded by the oil screen assembly 4, thereby effectively improving the oil guiding effect.

[0041] In this embodiment, the oil screen 42 is convexly arranged at the middle position of the fixed support 41, and the outer side wall of the fixed support 41 extends upward to form a flange 43. The inner side wall of the flange 43 cooperates with the outer side wall of the oil screen 42 to jointly define the oil guiding groove 44. The angle between the bottom wall of the oil guiding groove 44 and the horizontal line should be greater than 15°, thereby facilitating the oil to flow in the direction of the oil cup 2. No matter whether the air inlet 11 is in the closed state or the open state, the oil guiding hole 45 at the lower end position of the oil guiding groove 44 is located inside the smoke machine body 1. The oil on the first oil receiving member 6 or the second oil receiving member 7 is subjected to the action of gravity to flow to the upper end position of the oil guiding groove 44. The oil entering the oil guiding groove 44 continues to flow into the bottom wall of the smoke machine body 1 through the oil guiding hole 45 at the lower end position of the oil guiding groove 44, and is collected in the oil cup 2.

[0042] Further, a first flange is arranged outward at the top position of the inner side wall of the smoke guide plate 3 to form the first oil receiving member 6. The oil guiding hole 61 is arranged at both ends of the first oil receiving member 6 to discharge the oil on the first oil receiving member 6 outward. The structure is simple, and the first oil receiving member 6 can effectively collect the oil on the front side wall of the smoke machine body 1 no matter whether the air inlet 11 is in the closed state or the open state.

[0043] Preferably, the control panel 8 is further arranged on the smoke guide plate 3. The first oil receiving member 6 is provided with an oil blocking rib 62 extending upward after being bent at an end away from the smoke guide plate 3 to prevent the oil on the first oil receiving member 6 from flowing onto the control panel 8. The design is reasonable, and the first oil receiving member 6 not only collects the oil but also protects the control panel 8 from being contaminated by the oil, thereby effectively reducing the risk of short circuit of the electric control module.

[0044] Specifically, the second oil receiving member 7 is formed by extending the second flange outward from the inner wall of the smoke guide plate 3, and the oil screen assembly 4 is arranged at the middle position of the smoke guide plate 3 by extending the second flange downward after being bent away from one end of the smoke guide plate 3. The structure is simple, and the grease on the first oil receiving member 6 can be temporarily collected and then guided to the oil screen assembly 4.

[0045] In the embodiment, the front inner wall of the smoke machine body 1 is in the interception range of the first oil receiving member 6 arranged on the smoke guide plate 3, no matter the air inlet 11 is in the open state or the closed state, so that the grease on the front inner wall of the smoke machine body 1 can be smoothly guided to the first oil receiving member 6. The oil discharge holes 61 are arranged at both ends of the first oil receiving member 6 to discharge the grease on the first oil receiving member 6 outward, and the recess is arranged at the position of the oil discharge hole 61 of the first flange, so that when the grease on the first oil receiving member 6 flows to both ends, the grease can flow to the second oil receiving member 7 through the recess and the oil discharge hole 61 in turn. Thus, the grease guiding effect of the first oil receiving member 6 can be effectively improved. No matter the air inlet 11 is in the open state or the closed state, the grease collected on the second oil receiving member 7 can be guided to the oil guiding groove 44 of the oil screen assembly 4, and when the air inlet 11 is in the open state, the angle between the second flange and the horizontal line is greater than 15°, and the angle between the bent flange 71 and the horizontal line is less than 165°. In addition, when the air inlet 11 is in the open state, the first oil receiving member 6 collects the grease on the front inner wall of the smoke machine body 1, and the grease collected on the second oil receiving member 7 flows to the oil cup 2 through the oil guiding groove 44 of the oil screen assembly 4. When the air inlet 11 is in the closed state, the first oil receiving member 6 collects the grease on the front inner wall of the smoke machine body 1, and the grease in the first oil receiving member 6 flows to both ends to guide the grease on the first oil receiving member 6 to the second oil receiving member 7 through the oil discharge hole 61. Since the oil amount is relatively small after cooking, the grease is temporarily stored in the second oil receiving member 7, and when the storage amount of the grease in the second oil receiving member 7 exceeds the height of the second flange, the grease can be guided into the oil guiding groove 44 of the oil screen assembly 4, and then the grease in the oil guiding groove 44 is guided to the oil cup 2.

[0046] Further, the driving assembly includes a driving device and a connecting rod, wherein the driving device is installed in the smoke machine body 1, and the output end of the driving device is connected with the smoke guide plate 3 through the connecting rod. The structure is simple and compact, and the stability of the turning movement of the smoke guide plate 3 can be effectively improved.

[0047] Particularly, the rotating shaft 13 is arranged on the smoke machine body 1, and the upper end of the smoke guide plate 3 is rotatably connected with the smoke machine body 1 through the rotating shaft 13, which is simple in structure and facilitates the overturning movement of the smoke guide plate 3.

[0048] In the embodiment, the driving device is preferably a motor, but is not limited to the motor, and other more suitable driving units can be selected according to actual needs. In the embodiment, the driving device is exemplarily described by taking the motor, and the remaining types of driving units will not be described in detail. The driving device is symmetrically installed on the left and right ends in the smoke machine body 1. The connecting rod has a first connecting rod and a second connecting rod. The output end of the driving device is connected with the first connecting rod. The first connecting rod is hingedly connected with one end of the second connecting rod at an end away from the driving device. The other end of the second connecting rod is hingedly connected with the inner side wall of the smoke guide plate 3. The upper end of the smoke guide plate 3 is rotatably connected with the smoke machine body 1 through the rotating shaft 13. The middle position of the inner side wall is connected with one end of the oil screen assembly 4. The oil screen assembly 4 is slidably connected with the smoke machine body 1 through the guide rail 12 at an end away from the smoke guide plate 3. The driving device drives the second connecting rod to move through the first connecting rod. The smoke guide plate 3 is driven to overturn through the movement of the second connecting rod. The oil screen assembly 4 is driven to move forward and backward in the longitudinal direction through the overturning movement of the smoke guide plate 3. Thus, the front end of the smoke guide plate 3 rotates around the rotating shaft 13, and the rear end slides forward and backward on the guide rail 12 to guide the overturning movement of the oil screen assembly 4, so as to realize the opening or closing of the air inlet 11 by the oil screen assembly 4.

[0049] The above only describes some embodiments of the present application. Those skilled in the art can make several modifications and improvements without departing from the concept of the present application, which are all within the protection scope of the present application.
