In this embodiment, the base g is arranged as a wall, and the base surface is a wall surface. Of course, the base g can also be arranged as other structures, such as a shell, equipment, or other carriers. The smoke collecting device comprises a shell 1 with a smoke collecting cavity inside and a driving component 2. The shell 1 is slidingly arranged in the reserved groove g1, and two sides of the shell 1 are provided with smoke inlets 11 for sucking the oil fume on both sides of the shell 1 into the smoke collecting cavity. The driving component 2 is used to drive the shell 1 to translate, so that the shell 1 has a parking state hidden in the base g and a working state exposed outside the base g.

[0037] When the shell 1 is in the parking state, it is hidden in the base g. At this time, the shell 1 does not occupy the space outside the base g, on the one hand, making the kitchen space more spacious and tidy, on the other hand, avoiding the pollution of the shell 1 by oil fume, dust and other substances in the kitchen due to long-term exposure, maintaining the cleanliness of the surface of the shell 1, at the same time, reducing the risk of collision with the user due to the protrusion of the shell 1 from the base g, reducing the safety hazard. When the shell 1 is in the working state, it is exposed outside the base g. At this time, the smoke inlets 11 on both sides of the shell 1 can suck the oil fume on both sides of the shell 1 into the smoke collecting cavity, keeping the kitchen environment clean.

[0038] In this embodiment, the driving component 2 is used to drive the shell 1 to translate on the reserved groove g1, so that the user can switch the shell 1 between the parking state hidden in the base g and the working state exposed outside the base g according to the use demand, which not only meets the demand of saving space and cleaning, but also ensures the smoke suction function of the shell 1 during cooking.

[0039] In the embodiment, the front part of the shell 1 has a front end plate 12, when the shell 1 is in the stop state, the front end plate 12 is flush with the base surface, that is, the front end plate 12 is in a plane with the base surface, at this time, the shell 1 and the base form an integral whole, the integral visual effect is good, which helps to improve the value of the commodity, and the edge of the front end plate 12 is close to the edge corresponding to the opening g2, which can avoid that the dust, oil fume or other pollutants in the kitchen enter the reserved groove g1 from the opening g2 to pollute the shell 1. When the shell 1 is started, the shell 1 is gradually moved out from the stop state, that is, the front end plate 12 is flush with the base surface, until the maximum stroke outside the base g, at this time, the smoke inlet 11 is completely exposed outside the base g.

[0040] In the embodiment, the lower groove wall of the reserved groove g1 is provided with two sliding rails extending along the translation direction of the shell 1, and the shell 1 is provided with two sliding members corresponding to each sliding rail, the sliding members are arranged on the bottom of the shell 1 and are slidingly connected to the sliding rails. The sliding members are in the form of extending along the horizontal direction and protruding downward, and the sliding rails are in the form of long slot-shaped clamps recessed from top to bottom, that is, the sliding rails have sliding grooves extending along the translation direction of the shell 1, the sliding members are slidingly embedded in the sliding grooves, and the cooperation structure of the sliding rails and the sliding members can provide stable support for the shell 1 in the working state, and ensure the accuracy of the sliding direction of the shell 1.

[0041] In the embodiment, in order to improve the smoke suction effect of the smoke inlet 11, a smoke guide plate 3 is arranged at the smoke inlet 11, the smoke guide plate 3 is used to gather oil fume, and the smoke guide plate 3 can slide vertically relative to the shell 1 and gradually turn outward when sliding upward, after the smoke guide plate 3 turns outward, an smoke inlet channel can be formed between the smoke guide plate 3 and the smoke inlet 11, which reduces the escape and diffusion of oil fume, and the vertical sliding of the smoke guide plate 3 is driven by the driving assembly 2.

[0042] Specifically, the driving assembly 2 includes a driving mechanism 21 and a transmission mechanism 22, wherein the transmission mechanism 22 includes a first movable gear 221, a second movable gear 222 and a first output wheel 223 which can move along the left and right directions, a second output wheel 224 which is fixed in position and a driver 225, the first output wheel 223 and the second output wheel 224 are respectively used to drive the two side smoke guide plates 3 to slide vertically, the driving mechanism 21 is used to synchronously drive the first movable gear 221 and the second movable gear 222 to rotate and move in the same direction, so that the first movable gear 221 and the first output wheel 223 are combined, or the second movable gear 222 and the second output wheel 224 are combined, and the driver 225 is used to drive the first output wheel 223 to move and combine with the first movable gear 221.

[0043] When the first driving gear 221 and the first output wheel 223 are combined, the first output wheel 223 can drive the smoke guide plate 3 on one side to slide vertically, when the second driving gear 222 and the second output wheel 224 are combined, the second output wheel 224 can drive the smoke guide plate 3 on the other side to slide vertically, and since the driver 225 can drive the first output wheel 223 to move and combine with the first driving gear 221, when the first driving gear 221 and the first output wheel 223 are combined, the second driving gear 222 can also combine with the second output wheel 224, on this basis, the driving mechanism 2 can control the smoke guide plate 3 on one side to slide vertically respectively, or control the smoke guide plate 3 on both sides to slide vertically at the same time, that is, the user can selectively use the driving mechanism 21 to control the smoke guide plate 3 on one side or open the smoke guide plates on both sides of the shell 1 at the same time according to actual needs. For example, when only one side of the stove is cooking, only the smoke guide plate 3 on that side can be moved, and the smoke guide plate 3 on the other side is closed, thereby avoiding unnecessary noise and energy consumption.

[0044] In the embodiment, the driving mechanism 21 includes a driving motor 211 configured as a double-head motor, two rotating shafts 212 assembled on the driving motor 211, a first gear 213 and a second gear 214 connected to the two rotating shafts 212 respectively, and the two rotating shafts 212 are installed at both ends of the double-head motor. When the double-head motor works, it drives the two rotating shafts 212 to rotate synchronously, thereby driving the first gear 213 and the second gear 214 installed on the two rotating shafts 212 to rotate, and the first gear 213 and the first driving gear 221 are engaged and both are configured as bevel gears, the second gear 214 and the second driving gear 222 are engaged and both are configured as bevel gears, the first gear 213 and the second gear 214 are the same structure, the first driving gear 221 and the second driving gear 222 are the same structure, since the first gear 213 and the first driving gear 221 are engaged and both are configured as bevel gears, that is, the first gear 213 will generate a lateral thrust to the first driving gear 221 when rotating, so that the first driving gear 221 translates, therefore, when the double-head motor works, the rotating first gear 213 and the second gear 214 can drive the first driving gear 221 to move in the same direction as the second driving gear 222, and the moving direction of the first driving gear 221 and the second driving gear 222 can be controlled by the rotating direction of the double-head motor.

[0045] In the embodiment, the first output wheel 223 and the first driving gear 221 are respectively provided with a clamping groove 230 and a clamping tooth 229 on the opposite surfaces, and the clamping groove 230 and the clamping tooth 229 are clamped and matched to combine the first output wheel 223 and the first driving gear 221. The clamping structure of the clamping groove 230 and the clamping tooth 229 can realize the close connection between the first driving gear 221 and the first output wheel 223, ensure the transmission accuracy, and realize the installation of the first driving gear 221 and the first output wheel 223 by translating the first driving gear 221 without complex adjustment and calibration. Correspondingly, the second output wheel 224 and the second driving gear 222 are respectively provided with a clamping groove 230 and a clamping tooth 229 on the opposite surfaces, and the clamping groove 230 and the clamping tooth 229 are clamped and matched to combine the second output wheel 224 and the second driving gear 222. In addition, the clamping groove 230 and the clamping tooth 229 are arranged in a circumferential direction, and the stress condition of the clamping groove 230 and the clamping tooth 229 is more balanced when they are clamped and matched, so that the connection reliability is good when combined.

[0046] In the embodiment, the driving mechanism 21 further comprises two driving gears 215 connected to the two rotating shafts 212 respectively and two racks g4 engaged with the two driving gears 215. The two racks g4 are spaced apart from each other and engaged with the corresponding driving gears 215 respectively. The rack g4 is arranged on the groove wall of the reserved groove g1 and extends in the translation direction of the shell 1. The rack g4 is fixedly connected to the upper groove wall of the reserved groove g1. The driving motor 211 is arranged on the top of the shell 1. During operation, the double-head motor rotates to drive the driving gear 215 connected to the rotating shaft 212 to rotate, so that the rotating driving gear 215 can move linearly along the extension direction of the rack g4, thereby driving the driving motor 211 to translate, and further driving the shell 1 fixedly connected to the driving motor 211 to translate. The moving direction of the shell 1 can be adjusted by changing the rotating direction of the double-head motor.

[0047] Since the forward and backward translation of the shell 1 and the vertical movement of the smoke guide plate are both controlled by the double-head motor, in order to keep the position of the shell 1 stable when the shell 1 is in the working state, it is necessary to avoid the double-head motor driving the vertical lifting of the smoke guide plate and the translation of the shell 1 at the same time during operation. Therefore, the driving mechanism 21 further comprises a double-direction damper 216 sleeved on the rotating shaft 212. The driving gear 215 is connected to the double-direction damper 216. The double-direction damper 216 is provided with a threshold torque. When the output torque of the driving motor 211 is greater than the threshold torque, the double-direction damper 216 rotates. When the output torque of the driving motor 211 is less than the threshold torque, the double-direction damper 216 does not rotate. Therefore, when the shell is in the working state, only the output torque of the driving motor 211 needs to be adjusted, so that the driving gear 215 is in a fixed state when the rotating shaft 212 rotates.

[0048] In the embodiment, the cooperation structure of the driving mechanism 21 and the transmission mechanism 22 enables the two-sided smoke guide plates 3 to be respectively controlled to turn outwards by one double-head motor and simultaneously controlled to turn outwards, and the double-head motor is also capable of controlling the casing 1 to switch between the stop state hidden in the base g and the working state exposed outside the base g by setting the bidirectional damper 216 on the rotating shaft 212, which significantly simplifies the internal structure of the smoke collecting device and facilitates manufacturing.

In this embodiment, the base g is arranged as a wall, and the base surface is the wall surface. Of course, the base g can also be arranged as other structures, such as a machine shell, equipment or other carriers. The smoke collecting device comprises a housing 1 having a smoke collecting cavity inside and a driving component 2. The housing 1 is slidingly arranged in the reserved slot g1. Two sides of the housing 1 are provided with smoke inlets 11 for sucking the oil fume on both sides of the housing 1 into the smoke collecting cavity. The driving component 2 is used to drive the housing 1 to translate, so that the housing 1 has a parking state hidden in the base g and a working state exposed outside the base g.

[0070] When the housing 1 is in the parking state, it is hidden in the base g. At this time, the housing 1 does not occupy the space outside the base g. On the one hand, it makes the kitchen space more spacious and tidy. On the other hand, it avoids the pollution of the housing 1 by the oil fume, dust and other substances in the kitchen due to long-term exposure, maintains the cleanliness of the surface of the housing 1, and reduces the risk of collision with the user due to the protrusion of the housing 1 from the base g, thereby reducing the safety hazard. When the housing 1 is in the working state, it is exposed outside the base g. At this time, the smoke inlets 11 on both sides of the housing 1 can suck the oil fume on both sides of the housing 1 into the smoke collecting cavity, thereby keeping the kitchen environment clean.

[0071] In this embodiment, the driving component 2 is used to drive the housing 1 to translate on the reserved slot g1, so that the user can switch the housing 1 between the parking state hidden in the base g and the working state exposed outside the base g according to the use demand. This not only meets the needs of saving space and cleaning, but also ensures the smoke suction function of the housing 1 during cooking.

[0072] In the embodiment, the front part of the shell 1 has a front end plate 12, when the shell 1 is in the stop state, the front end plate 12 is flush with the base surface, that is, the front end plate 12 is in a plane with the base surface, at this time, the shell 1 and the base form an integral whole, the integral visual effect is good, which helps to improve the value of the commodity, and the edge of the front end plate 12 is close to the edge corresponding to the opening g2, which can avoid that the dust, oil fume or other pollutants in the kitchen enter the reserved groove g1 from the opening g2 to pollute the shell 1. When the shell 1 is started, the shell 1 is gradually moved out from the stop state, that is, the front end plate 12 is flush with the base surface, until the maximum stroke outside the base g, at this time, the smoke inlet 11 is completely exposed outside the base g.

[0073] In the embodiment, the lower groove wall of the reserved groove g1 is provided with two sliding rails extending along the translation direction of the shell 1, and the shell 1 is provided with two sliding members corresponding to each sliding rail, the sliding members are arranged on the bottom of the shell 1 and are slidingly connected to the sliding rails. The sliding members are in the form of extending along the horizontal direction and protruding downward, and the sliding rails are in the form of long slot-shaped clamps recessed from top to bottom, that is, the sliding rails have sliding grooves extending along the translation direction of the shell 1, the sliding members are slidingly embedded in the sliding grooves, and the cooperation structure of the sliding rails and the sliding members can provide stable support for the shell 1 in the working state, and ensure the accuracy of the sliding direction of the shell 1.

[0074] In the embodiment, in order to improve the smoke suction effect of the smoke inlet 11, a smoke guide plate 3 is arranged at the smoke inlet 11, the smoke guide plate 3 is used to gather oil fume, and the smoke guide plate 3 can slide vertically relative to the shell 1 and gradually turn outward when sliding upward, after the smoke guide plate 3 turns outward, an smoke inlet channel can be formed between the smoke guide plate 3 and the smoke inlet 11, which reduces the escape and diffusion of oil fume, and the vertical sliding of the smoke guide plate 3 is driven by the driving assembly 2.

[0075] Specifically, the driving assembly 2 includes a driving mechanism 21 and a transmission mechanism 22, wherein the transmission mechanism 22 includes a first movable gear 221, a second movable gear 222 and a first output wheel 223 which can move along the left and right directions, a second output wheel 224 which is fixed in position and a driver 225, the first output wheel 223 and the second output wheel 224 are respectively used to drive the two side smoke guide plates 3 to slide vertically, the driving mechanism 21 is used to synchronously drive the first movable gear 221 and the second movable gear 222 to rotate and move in the same direction, so that the first movable gear 221 and the first output wheel 223 are combined, or the second movable gear 222 and the second output wheel 224 are combined, and the driver 225 is used to drive the first output wheel 223 to move and combine with the first movable gear 221.

[0076] When the first driving gear 221 and the first output wheel 223 are combined, the first output wheel 223 can drive the smoke guide plate 3 on one side to slide vertically, when the second driving gear 222 and the second output wheel 224 are combined, the second output wheel 224 can drive the smoke guide plate 3 on the other side to slide vertically, and since the driver 225 can drive the first output wheel 223 to move and combine with the first driving gear 221, when the first driving gear 221 and the first output wheel 223 are combined, the second driving gear 222 can also combine with the second output wheel 224, on this basis, the driving mechanism 2 can control the smoke guide plate 3 on one side to slide vertically respectively, or control the smoke guide plate 3 on both sides to slide vertically at the same time, that is, the user can selectively use the driving mechanism 21 to control the smoke guide plate 3 on one side or open the smoke guide plates on both sides of the shell 1 at the same time according to actual needs. For example, when only one side of the stove is cooking, only the smoke guide plate 3 on that side can be moved, and the smoke guide plate 3 on the other side is closed, thereby avoiding unnecessary noise and energy consumption.

[0077] In the embodiment, the driving mechanism 21 includes a driving motor 211 configured as a double-head motor, two rotating shafts 212 assembled on the driving motor 211, a first gear 213 and a second gear 214 connected to the two rotating shafts 212 respectively, and the two rotating shafts 212 are installed at both ends of the double-head motor. When the double-head motor works, it drives the two rotating shafts 212 to rotate synchronously, thereby driving the first gear 213 and the second gear 214 installed on the two rotating shafts 212 to rotate respectively, and the first gear 213 and the first driving gear 221 are engaged and both are configured as bevel gears, the second gear 214 and the second driving gear 222 are engaged and both are configured as bevel gears, the first gear 213 and the second gear 214 are the same structure, the first driving gear 221 and the second driving gear 222 are the same structure, since the first gear 213 and the first driving gear 221 are engaged and both are configured as bevel gears, that is, the first gear 213 will generate a lateral thrust to the first driving gear 221 when rotating, so that the first driving gear 221 translates, therefore, when the double-head motor works, the rotating first gear 213 and the second gear 214 can drive the first driving gear 221 to move in the same direction as the second driving gear 222, and the moving direction of the first driving gear 221 and the second driving gear 222 can be controlled by the rotating direction of the double-head motor.

[0078] In the embodiment, the first output wheel 223 and the first driving gear 221 are respectively provided with a clamping groove 230 and a clamping tooth 229 on the opposite surfaces, and the clamping groove 230 and the clamping tooth 229 are clamped and matched to combine the first output wheel 223 and the first driving gear 221. The clamping structure of the clamping groove 230 and the clamping tooth 229 can realize the close connection between the first driving gear 221 and the first output wheel 223, ensure the transmission accuracy, and realize the installation of the first driving gear 221 and the first output wheel 223 by translating the first driving gear 221 without complex adjustment and calibration. Correspondingly, the second output wheel 224 and the second driving gear 222 are respectively provided with a clamping groove 230 and a clamping tooth 229 on the opposite surfaces, and the clamping groove 230 and the clamping tooth 229 are clamped and matched to combine the second output wheel 224 and the second driving gear 222. In addition, the clamping groove 230 and the clamping tooth 229 are arranged in a circumferential direction, and the stress condition of the clamping groove 230 and the clamping tooth 229 is more balanced when they are clamped and matched, so that the connection reliability is good when combined.

[0079] In the embodiment, the driving mechanism 21 further comprises two driving gears 215 connected to the two rotating shafts 212 respectively and two racks g4 engaged with the two driving gears 215. The two racks g4 are spaced apart from each other and engaged with the corresponding driving gears 215 respectively. The rack g4 is arranged on the groove wall of the reserved groove g1 and extends in the translation direction of the shell 1. The rack g4 is fixedly connected to the upper groove wall of the reserved groove g1. The driving motor 211 is arranged on the top of the shell 1. During operation, the double-head motor rotates to drive the driving gear 215 connected to the rotating shaft 212 to rotate, so that the rotating driving gear 215 can move linearly along the extension direction of the rack g4, thereby driving the driving motor 211 to translate, and further driving the shell 1 fixedly connected to the driving motor 211 to translate. The moving direction of the shell 1 can be adjusted by changing the rotating direction of the double-head motor.

[0080] Since the forward and backward translation of the shell 1 and the vertical movement of the smoke guide plate are both controlled by the double-head motor, in order to keep the position of the shell 1 stable when the shell 1 is in the working state, it is necessary to avoid the double-head motor driving the vertical lifting of the smoke guide plate and the translation of the shell 1 at the same time during operation. Therefore, the driving mechanism 21 further comprises a double-direction damper 216 sleeved on the rotating shaft 212. The driving gear 215 is connected to the double-direction damper 216. The double-direction damper 216 is provided with a threshold torque. When the output torque of the driving motor 211 is greater than the threshold torque, the double-direction damper 216 rotates. When the output torque of the driving motor 211 is less than the threshold torque, the double-direction damper 216 does not rotate. Therefore, when the shell is in the working state, only the output torque of the driving motor 211 needs to be adjusted, so that the driving gear 215 is in a fixed state when the rotating shaft 212 rotates.

[0081] In the embodiment, the cooperation structure of the driving mechanism 21 and the transmission mechanism 22 enables the two-sided smoke guide plates 3 to be respectively controlled to turn outwards by one double-head motor and simultaneously controlled to turn outwards, and the double-head motor is also capable of controlling the casing 1 to switch between the stop state hidden in the base g and the working state exposed outside the base g by setting the bidirectional damper 216 on the rotating shaft 212, which significantly simplifies the internal structure of the smoke collecting device and facilitates manufacturing.
