The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0034] Example 1,

[0035] A smoke collecting device is applied in a kitchen environment, mainly used for collecting and guiding the oil fume generated by the cooking on the cooking stove into the inside of the range hood, referring to Figures 1-13 The base g is provided with a reserved groove g1, and the reserved groove g1 is formed with an opening g2 on the base surface. In this embodiment, the base g is provided as a wall, and the base surface is a wall surface. Of course, the base g can also be provided as other structures, such as a shell, equipment, and 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. 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.

[0036] 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, it makes the kitchen space appear more spacious and tidy. On the other hand, it avoids the shell 1 being polluted by oil fume, dust and other substances in the kitchen for a long time, maintains the cleanliness of the surface of the shell 1, reduces the risk of collision with the user caused by the shell 1 protruding from the base g, and reduces 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.

[0037] 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. It not only meets the needs of saving space and cleaning, but also ensures the smoke suction function of the shell 1 during cooking.

[0038] In this embodiment, the front part of the shell 1 has a front end plate 12. When the shell 1 is in the parking state, the front end plate 12 is flush with the base surface, i.e. the front end plate 12 and the base surface are in the same plane. At this time, the shell 1 and the base g form a whole, which has a good visual effect and helps to improve the value of the product. Moreover, the edge of the front end plate 12 closely abuts the corresponding edge of the opening g2, which can prevent the dust, oil fume or other pollutants in the kitchen from entering the reserved groove g1 through the opening g2 and polluting the shell 1. When the shell 1 is started, the shell 1 gradually moves out from the parking state, i.e. the state that the front end plate 12 is flush with the base surface, until it moves out of the base g to the maximum stroke. At this time, the smoke inlets 11 are completely exposed outside the base g.

[0039] In the embodiment, the lower groove wall of the reserved groove g1 is provided with two slide rails extending along the translation direction of the shell 1, and the shell 1 is provided with two sliding members corresponding to each slide rail, the sliding members are arranged on the bottom of the shell 1 and are slidingly connected to the slide rails. The sliding members are in the form of extending horizontally and protruding downward, and the slide rails are in the form of long slot-shaped notches recessed from top to bottom, that is, the slide rails have slide grooves extending along the translation direction of the shell 1, the slide grooves extend along the translation direction of the shell 1, and the sliding members are slidingly fitted in the slide grooves. The cooperation structure of the slide rails and the sliding members can provide stable support when the shell 1 is in the working state, and ensure the accuracy of the sliding direction of the shell 1.

[0040] In the embodiment, in order to improve the smoking 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 the oil fume, the smoke guide plate 3 is vertically slidable relative to the shell 1, and the smoke guide plate 3 gradually turns outward when it is upwardly slid, after the smoke guide plate 3 turns outward, an oil fume inlet channel is formed between the smoke guide plate 3 and the smoke inlet 11, which reduces the escape and diffusion of the oil fume, and the vertical sliding of the smoke guide plate 3 is driven by the driving assembly 2.

[0041] 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 are movable along the left-right direction, 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 vertically slide, 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.
