The smoke exhausting and backflow preventing functions of the smoke machine are achieved through opening and closing of the air outlet cover.

However, the exhaust hood structure of the prior art smoke machine design has a defect, fig. 1 shows a schematic structural diagram of an exhaust hood of a smoke machine in the related art, as shown in fig. 1, the exhaust hood 00 adopted by the smoke machine includes: the cover body 01, the connecting frame 02, the valve block 03, axis of rotation 04, wherein, this air-out cover 00 adopts two solitary valve block 03, and every valve block 03 can revolute axis of rotation 04 and rotate, and when the cigarette machine during operation, under the effect of wind pressure, two valve blocks 03 can revolute axis of rotation 04 and open the air outlet, and after the cigarette machine is closed, valve block 03 is under the effect of self gravity, revoluted axis of rotation 04 and is fallen, plays the shutoff effect to the air outlet, prevents that outside air from flowing backward into inside the cigarette machine.

Therefore, when the smoke ventilator works, the condition that the rotation angle of the valve plate 03 is small due to insufficient wind pressure can occur, so that the air outlet is not completely opened. In the long-time use process, the air outlet can condense oil stain. When the smoke machine does not work, the self gravity of the valve plate 03 is abutted against, the obstruction of oil stains cannot be overcome, so that a gap is reserved between the valve plate and the air outlet when the air outlet cover 00 is closed, the blocking effect of the air outlet cover 00 is poor, and the smoke in the public channel flows backward into the smoke machine and enters a room.

The application provides a cigarette machine, has solved the cigarette machine when not working, the relatively poor problem of shutoff effect of the air outlet of air-out cover.

In a first aspect, embodiments of the present application provide a smoke machine. As shown in fig. 2 and 3, the range 1000 includes a housing 10, an exhaust duct, a blower, an outlet hood 20, and a damper device 30.

It will be appreciated that as shown in fig. 4, the housing 10 is formed with an exhaust passage 11, and the exhaust passage 11 is used for exhausting the oil smoke. A fan 12 is arranged in the shell 10, and the fan 12 is arranged in the air draft channel 11.

As shown in fig. 5, the exhaust channel 11 has a first air inlet 111 and a first air outlet 112, the first air inlet 111 and the first air outlet 112 are arranged along the flow direction of the oil smoke, and the fan 12 is arranged in the exhaust channel 11 and is used for extracting the indoor oil smoke, so that the indoor oil smoke enters the exhaust channel 11 through the first air inlet 111 and is discharged from the first air outlet 112.

The air inlet side of the fan 12 is communicated with the first air inlet 111 of the air suction channel 11. The air outlet side of the fan 12 is communicated with the first air outlet 112 of the air suction channel 11.

Thus, when the extractor 1000 is in use, the blower 12 is activated to generate suction. Under the action of the fan 12, kitchen oil smoke enters the air suction channel 11 from the first air inlet 111 and is discharged through the first air outlet 112 of the air suction channel 11.

The housing 10 in the embodiment of the present application is a mechanism on the smoke ventilator 1000 for protecting the internal structure and collecting the smoke inside, so that the smoke is delivered to the outside of the air outlet cover 20. Depending on the different models of the cigarette machine 1000, the type of the casing 10 may be a top-suction type cigarette machine casing as shown in fig. 6, a side-suction type cigarette machine casing as shown in fig. 7, an intelligent cigarette machine casing with an intelligent system added thereto, etc. The shape of the housing 10 may be a regular three-dimensional structure, such as a cylinder, a cuboid, or the like, or alternatively, the shape of the housing 10 may be an irregular three-dimensional structure, such as a triangular platform, a combination of a cuboid and a cylinder, or the like, which is not particularly limited in this application.

The fan 12 in the air draft channel 11 can be a variable frequency fan, a constant speed fan, a blower fan and the like. One fan 12 can be arranged in the exhaust channel 11, and two or more fans 12 can be arranged, so that the extraction speed and the discharge speed of the lampblack can be controlled by increasing or decreasing the number of the fans 12. The kind and number of fans 12 are not particularly limited in this application.

As shown in fig. 8, the air outlet cover 20 is disposed at the first air outlet 112 of the air suction channel 11 and is connected to the housing 10. As shown in fig. 9 and 10, the air outlet cover 20 is provided with an air outlet channel 21, and the air outlet channel 21 has a second air inlet 211 and a second air outlet 212.

The air outlet channel 21 is connected to the first air outlet 112 of the air suction channel 11 and the outside, and is configured to receive the oil smoke discharged from the first air outlet 112 and discharge the received oil smoke out of the room.

Specifically, the second air inlet 211 of the air outlet channel 21 is communicated with the first air outlet 112 of the air draft channel 11, and the air outlet of the air outlet channel 21 is connected with the outside.

In this way, the fume absorbed by the fume extractor 1000 can be transmitted to the outside through the air outlet cover 20, and the fume emission and the backflow prevention can be realized by controlling the opening and closing of the second air outlet 212 of the air outlet passage 21.

In addition, as shown in fig. 11, the damper device 30 includes a moving plate 31 and a driving assembly 32.

The moving plate 31 is disposed at the second air outlet 212 of the air outlet channel 21 and is used for opening or closing the second air outlet 212 of the air outlet channel 21, and the driving component 32 is disposed on the air outlet cover 20 and connected with the moving plate 31, wherein the driving component 32 can drive the moving plate 31 to slide on a plane perpendicular to the axial direction of the air outlet channel 21, so that the moving plate 31 can open or close the second air outlet 212 of the air outlet channel 21. Specifically, the driving component 32 is disposed on a side surface of the air outlet housing 20 where the second air outlet 212 is located.

The moving plate 31 is located at the second air outlet 212 of the air outlet channel 21 and slides on a plane perpendicular to the axial direction of the air outlet channel 21, so that the moving plate 31 can slide on the plane where the second air outlet 212 of the air outlet channel 21 is located, and at least part of the moving plate 31 is attached to the second air outlet 212 in the moving process until the moving plate 31 completely opens the second air outlet 212. When the smoke ventilator 1000 works, the driving component 32 can drive the movable plate 31 to completely open the second air outlet 212, at this time, the opening degree of the second air outlet 212 is larger, and the blocking of the movable plate 31 to the smoke exhausted from the second air outlet 212 can be reduced, so that a good smoke exhausting effect can be realized.

And, the second air outlet 212 is fully opened, so that the accumulation of the oil smoke at the second air outlet 212 can be reduced, and the influence of the accumulated oil smoke on the closing of the second air outlet 212 by the movable plate 31 is avoided.

After the smoke ventilator stops working, the movable plate 31 can be driven by the driving component 32 to completely close the second air outlet 212, in this process, at least part of the movable plate 31 is attached to the second air outlet 212, and the accumulated smoke at the second air outlet 212 can be pushed and scraped, so that the accumulated smoke at the second air outlet 212 is further reduced, and the situation that the accumulated smoke is accumulated to cause a large gap between the movable plate 31 and the second air outlet 212 is avoided, so that the sealing effect of the movable plate 31 to the second air outlet 212 can be improved.

The movable plate 31 has a good sealing effect on the second air outlet 212, and can effectively prevent the lampblack in the public channel from flowing back into the room from the air outlet channel and the air draft channel, so that the indoor air can be ensured to be fresh.

The shape of the movable plate 31 may be a circular plate, a square plate, or a plate having other irregular shapes, which is not limited in this application.

In one possible implementation, as shown in fig. 12, the driving assembly 32 includes a motor 3211 and a first connecting rod 3212, where the motor 3211 is fixed to the air outlet cover 20. Specifically, the motor 3211 is fixed to a side surface of the air outlet cover 20 where the second air outlet 212 is located.

One end of the first connecting rod 3212 is connected to the moving plate 31, and an output shaft of the motor 3211 is connected to the other end of the first connecting rod 3212.

When the smoke ventilator 1000 works, the output shaft of the motor 3211 rotates forward to drive the first connecting rod 3212 to rotate around the motor 3211, the first connecting rod 3212 drives the moving plate 31 to slide to open the second air outlet 212 of the air outlet channel 21, and the smoke ventilator 1000 starts to discharge smoke. When the smoke ventilator 1000 is stopped, the motor 3211 drives the first connecting rod 3212 to rotate reversely around the motor 3211, and the first connecting rod 3212 drives the moving plate 31 to reset and block the second air outlet 212 of the air outlet channel 21.

In this way, the motor 3211 and the first connecting rod 3212 can drive the moving plate 31 to open and close the second air outlet 212 of the air outlet channel 21, so that the structure is simple in design and the cost can be reduced.

In addition, the first connecting rod 3212 is driven to rotate by the motor 3211, so that the moving track of the moving plate 31 is arc-shaped in the moving process of the moving plate 31, and the space occupied by the moving plate 31 after the second air outlet 212 is opened is smaller, so that the volume of the smoke ventilator 1000 can be reduced, and the applicability of the smoke ventilator 1000 is improved.

For example, the connection of one end of the first connecting rod 3212 to the moving plate 31 may be a fixed connection, such as welding, riveting, etc., in which case there is no relative movement between the first connecting rod 3212 and the moving plate 31.

For example, the connection between one end of the first connecting rod 3212 and the moving plate 31 may be detachable, for example, by screws, bolts, etc., in which the first connecting rod 3212 and the moving plate 31 are relatively easy to be detached and installed, thereby facilitating replacement of parts.

Illustratively, the connection between one end of the first connecting rod 3212 and the moving plate 31 may be a rotational connection, for example, by means of a pin, a bearing, or the like, to achieve the rotational connection between the first connecting rod 3212 and the moving plate 31. The present application is not particularly limited thereto.

In another possible implementation, the driving assembly 32 includes an electric pushrod, which is fixed to the air outlet cover 20, and an output shaft of the electric pushrod is connected to the moving plate 31. The connection between the output shaft of the electric putter and the moving plate 31 may be a fixed connection, a detachable connection, or the like.

In this way, accurate transmission between the first transmission part 3233 and the second transmission part 3243 can be realized, so that the movement of the first moving plate 311 and the second moving plate 312 is smoother, and larger power can be transmitted through the gear tooth meshing transmission mode, so that the first moving plate 311 and the second moving plate 312 can be effectively driven to move.
