[0003] At present, the smoke outlets of integrated stoves at home and abroad are mainly circular and rectangular in shape. The smoke outlets are flat on the stove surface, which causes the distance between the smoke outlets and the heating area on the stove surface to be closer than the oil fume area on the stove surface. During the cooking process of the integrated stove using such smoke outlets, it is difficult for the oil fume to be sucked away by the smoke outlet along a parabolic trajectory, resulting in poor overall smoke extraction effect of the integrated stove. At the same time, the smoke outlet will also absorb part of the heat of the stove, resulting in unsatisfactory cooking effect of the stove.

[0004] The existing electric smoke-inhaler liftable integrated stove is powered by a cylindrical reduction motor, and a push rod is used to push the smoke-inhaler plate at the smoke-inhaler port to make a cylindrical motion, so as to lift and lower the smoke-inhaler plate at the smoke-inhaler port along a fixed track and increase the smoking height of the smoke-inhaler plate.

[0030] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the present invention applies the smoking device to a combined device with a smoking device and a stove, which is only a preferred embodiment and is not a limitation on the scope of application of the smoking device of the present invention. For example, the smoking device of the present invention can also be applied to other gas appliances, and such adjustment falls within the protection scope of the smoking device of the present invention.

[0031] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

Therefore, the example term "below..." may include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0035] like Figures 1 to 3 As shown, according to an embodiment of the first aspect of the present invention, the first aspect of the present invention provides a smoking device 100, which includes a smoking tube 20 and a lifting mechanism (described in detail below). The smoking tube 20 is arranged at a smoking port 101 of a stove (not shown in the figure), and the oil smoke generated by the stove flows to the smoking port 101 through the smoking tube 20. The lifting mechanism includes a driving assembly 30 and a connecting rod assembly 40. The connecting rod assembly 40 is arranged in the stove and is circumferentially connected to the smoking tube 20. The driving assembly 30 drives the smoking tube 20 to rise and fall at the smoking port 101 through the connecting rod assembly 40.

[0036] When the stove is in use, the smoking device 100 of the present invention drives the smoking tube 20 to rise at the smoking port 101 through the lifting mechanism, and absorbs the oil smoke on the stove through the smoking tube 20. When the stove is in a resting state, the smoking tube 20 is driven to descend at the smoking port 101 through the lifting mechanism, reducing the space occupied by the smoking device 100, thereby improving the user experience. Specifically, a panel 10 is provided on the stove, and one or more gas stoves can be provided on the panel 10 of the stove. For example, two gas stoves are provided on the panel 10 of the stove at intervals. A smoking port 101 is provided at a position between the two gas stoves on the panel 10 of the stove, and a storage space located below the smoking port 101 is provided at a position between the two gas stoves in the stove. A fan is provided at the bottom of the storage space, and a smoking device 100 is provided at the top of the storage space at the smoking port 101. The smoking device 100 includes a smoking tube 20 that is gap-matched with the smoking port 101 and a driving mechanism for driving the smoking tube 20 to rise and fall. The fan is connected to the smoking tube 20 of the smoking device 100. When the gas stove is in working state, the smoking tube 20 is provided at the bottom of the storage space. When the gas stove is in the resting state, the lifting mechanism of the smoking device 100 drives the smoking tube 20 to descend to the bottom of the panel 10, and the cover plate around the smoking tube 20 covers the gap between the side wall of the smoking tube 20 and the smoking port 101, thereby reducing the chance of debris on the stove top falling into the smoking tube 20 through the gap between the side wall and the smoking port 101.

[0037] Furthermore, the driving assembly 30 of the above-mentioned embodiment drives the smoking tube 20 to rise and fall through the connecting rod assembly 40, and the connecting rod assembly 40 is circumferentially connected to the smoking tube 20, which can improve the stability of the smoking tube 20 during the lifting process, reduce the phenomenon of local stress concentration in the smoking tube 20 during the lifting process, and reduce the damage of the smoking tube 20 due to stress concentration and the phenomenon of shaking back and forth and left and right during the lifting process. It should be noted that the connecting rod assembly 40 can use two-link, three-link, four-link or other multi-link structures. The specific structure of the connecting rod assembly 40 will be described in detail below. The connecting rod assembly 40 is connected to the smoking tube 20 through multiple connecting rods. The driving assembly 30 achieves the purpose of synchronous movement of multiple connecting rods by driving at least one connecting rod in the connecting rod assembly 40. Multiple connecting rods drive the smoking tube 20 to rise and fall at the same time, thereby reducing the phenomenon of local stress concentration in the smoking tube 20 and improving the stability of the smoking tube 20 during the lifting process.

[0038] like Figure 4 and Figure 5According to one embodiment of the present invention, the connecting rod assembly 40 includes a first connecting rod 41 and a second connecting rod 42 that are cross-connected, and the first end 411 of the first connecting rod 41 is horizontally slidably connected to the smoke pipe 20, the second end 412 of the first connecting rod 41 is horizontally slidably connected to the stove top, the first end 421 of the second connecting rod 42 is rotatably connected to the stove top, and the second end 422 of the second connecting rod 42 is horizontally slidably connected to the smoke pipe 20.

[0039] In this embodiment, the first connecting rod 41 and the second connecting rod 42 are pivotally connected by the first axial screw 33. When the driving assembly 30 drives any connecting rod in the connecting rod assembly 40, for example, the driving assembly 30 drives the first connecting rod 41 and / or the second connecting rod 42, the second connecting rod 42 of the connecting rod assembly 40 can rotate with the first end 421 of the second connecting rod 42 as a fulcrum, and the second connecting rod 42 drives the first axial screw 33 to rotate during the rotation process. The first axial screw 33 rises and falls in the vertical direction during the rotation process. The first axial screw 33 drives the second end 422 of the second connecting rod 42 and the first end 411 of the first connecting rod 41 to rise and fall during the lifting process. The second end 422 of the second connecting rod 42 and the first end 411 of the first connecting rod 41 drive the smoking pipe 20 to rise and fall during the lifting process. Furthermore, in order to prevent the second connecting rod 42 from getting stuck during the rotation process, the second end 412 of the first connecting rod 41 is horizontally slidably connected to the stove top, and the second end 422 of the second connecting rod 42 is horizontally slidably connected to the smoking pipe 20. During the rotation of the second connecting rod 42, the second end 412 of the first connecting rod 41 slides horizontally along the stove top, and a flange structure is formed at the second end 422 of the second connecting rod 42. The flange structure slides horizontally in the waist-shaped hole (not shown in the figure) of the smoking pipe 20 through the axial screw.

[0040] Furthermore, the smoking device 100 further includes a mounting plate assembly 11 disposed on the inner wall of the panel 10, the driving assembly 30 and a part of the connecting rod assembly 40 are disposed on the mounting plate assembly 11, specifically, the mounting plate assembly 11 includes a first mounting plate 111 and a second mounting plate 112 disposed on the inner wall of the panel 10 and located around the smoking port 101, the first end 411 of the first connecting rod 41 is horizontally slidably connected to the waist-shaped hole 21 of the smoking tube 20, and the second end 412 of the first connecting rod 41 is horizontally slidably connected to the second mounting plate 111. 12, the first end 421 of the second connecting rod 42 is rotatably connected to the through hole on the first mounting plate 111, and the second end 422 of the second connecting rod 42 is horizontally slidably connected to the waist-shaped hole (not shown in the figure) of the smoking tube 20. The mounting plate assembly 11 also includes a support plate arranged on the inner wall of the panel 10 and away from the smoking port 101. The driving assembly 30 is installed on the support plate. The driving assembly 30 is arranged at a position away from the smoking port 101, which can reduce the influence of the oil smoke at the smoking port 101 on the driving assembly 30.

[0041] It should be noted that the driving component 30 in the above embodiment can be operated manually or automatically. When the driving component 30 is operated manually, one end of the driving component 30 extends out of the stove, and the other end of the driving component 30 is connected to the connecting rod assembly. The user can drive the other end of the driving component 30 to drive the connecting rod assembly 40 by operating one end of the driving component 30, so as to achieve the purpose of controlling the lifting and lowering of the smoke pipe 20 at the smoking port 101.

[0042] When the drive assembly 30 is in automatic operation mode, such as Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, the driving assembly 30 includes a push rod motor and a controller (not shown in the figure). The push rod motor is arranged in the stove and electrically connected to the controller. The push rod motor operates according to the driving signal sent by the controller. Furthermore, a rocker arm 31 is arranged on the push rod of the push rod motor, and the rocker arm 31 is rotatably connected to the second end 412 of the first connecting rod 41.

[0043] In this embodiment, the push rod of the push rod motor is rotatably connected to the rocker arm 31 through a pin shaft 32. Since the second end 412 of the first connecting rod 41 is horizontally slidably connected to the long hole on the second mounting plate 112, and the push rod of the push rod motor is rotatably connected to the second end 412 of the first connecting rod 41 through the rocker arm 31, the push rod converts the axial force of the push rod into a horizontal thrust on the second end 412 of the first connecting rod 41 through the rocker arm 31, thereby improving the applicability of the push rod motor to the installation state. For example, the push rod motor and the push rod can be installed in the stove in a horizontal direction, and can also be installed in the stove in a vertical direction or an inclined direction.

[0044] Continue reading Figures 1 to 5 According to one embodiment of the present invention, the connecting rod assembly 40 also includes a third connecting rod 43 and a fourth connecting rod 44 cross-connected to the side of the smoke pipe 20 opposite to the first connecting rod 41 and the second connecting rod 42, and the first end of the third connecting rod 43 is horizontally slidably connected to the smoke pipe 20, the second end of the third connecting rod 43 is horizontally slidably connected to the third mounting plate 113 on the stove top, the first end of the fourth connecting rod 44 is rotatably connected to the stove top, and the second end of the fourth connecting rod 44 is horizontally slidably connected to the smoke pipe 20.

[0045] In this embodiment, the third connecting rod 43 and the fourth connecting rod 44 are pivotally connected by the second axial screw 34. By cross-connecting the third connecting rod 43 and the fourth connecting rod 44 to the side of the smoking tube 20 opposite to the first connecting rod 41 and the second connecting rod 42, the supporting stability of the connecting rod assembly 40 on the smoking tube 20 can be further improved, that is, the first connecting rod 41 and the second connecting rod 42 support the smoking tube 20 on one side of the smoking tube 20, and the third connecting rod 43 and the fourth connecting rod 44 support the smoking tube 20 on the other side of the smoking tube 20, thereby reducing the deviation of the smoking tube 20 during the lifting process. Specifically, during the lifting process of the smoking tube 20, the first end of the third connecting rod 43 and the second end of the fourth connecting rod 44 are driven to slide in the horizontal direction on the smoking tube 20, and at the same time, the second end of the third connecting rod 43 is driven to slide in the horizontal direction on the stove, and the first end of the fourth connecting rod 44 is driven to rotate on the stove, so as to achieve the purpose of lifting and lowering the third connecting rod 43 and the fourth connecting rod 44 in the vertical direction.

[0046] Continue reading Figure 4 and Figure 5 According to one embodiment of the present invention, the first link 41, the second link 42, the third link 43 and the fourth link 44 are all bending rods, and the connecting part between the first link 41 and the second link 42 and the connecting part between the third link 43 and the fourth link 44 are both located at the top of the bending rod.

[0047] In this embodiment, the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 are set as bending rods, which can reduce the longitudinal space of the smoking pipe 20 occupied by the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 and increase the lifting range of the smoking pipe 20. That is, the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 can be set at a position located at the bottom of the smoking pipe 20 to reduce the interference between the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 and the smoking port 101 on the panel 10 during the lifting process of the smoking pipe 20.

[0048] Continue reading Figure 4 and Figure 5 , the first end 411 of the first link 41, the second end 422 of the second link 42, the first end of the third link 43 and the second end of the fourth link 44 are in the same horizontal state, and the second end 412 of the first link 41, the first end 421 of the second link 42, the second end of the third link 43 and the first end of the fourth link 44 are in the same horizontal state.

[0049] In this embodiment, the first end 411 of the first connecting rod 41, the second end 422 of the second connecting rod 42, the first end of the third connecting rod 43 and the second end of the fourth connecting rod 44 are in the same horizontal state, and the second end 412 of the first connecting rod 41, the first end 421 of the second connecting rod 42, the second end of the third connecting rod 43 and the first end of the fourth connecting rod 44 are in the same horizontal state, which can improve the synchronization of the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44, and improve the force uniformity of the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44, thereby reducing the uneven force or offset of the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 during the lifting and lowering of the smoking pipe 20.

[0050] Continue reading Figure 2 According to one embodiment of the present invention, two opposite side walls of the smoke pipe 20 corresponding to the oil smoke area on the stove are provided with a plurality of smoke inlet holes, and a grille plate (not shown in the figure) is provided on the top of the smoke pipe 20.

[0051] In this embodiment, taking two gas stoves arranged at intervals on the panel 10 of the stove as an example, the smoke outlet 101 is arranged in the area between the two gas stoves on the panel 10, and multiple smoke inlet holes are arranged on the two side walls of the smoke tube 20 facing the two gas stoves. When the stove is in operation, the fan draws air from the smoke tube 20, so that negative pressure is formed at the multiple smoke inlet holes, and the oil smoke on the stove enters the smoke tube 20 through the multiple smoke inlet holes and is discharged to the outside of the stove through the exhaust pipe on the fan. Furthermore, a grille plate is arranged on the top of the smoke tube 20, and the gaps between the grille plates form a flow channel for the oil smoke, so that the oil smoke on the stove can flow to the smoke tube 20 through the gaps between the grille plates. At the same time, the multiple grille plates can reduce the debris on the stove from falling into the smoke tube 20 through the top of the smoke tube 20.

[0052] Continue reading Figure 3 The smoking device 100 further includes a smoke shield 12 disposed on the inner wall of the panel 10 . The smoke shield 12 is disposed around the smoking port 101 and gradually shrinks toward the bottom of the stove to form a smoke collecting port 121 .

[0053] In the present embodiment, the smoke hood 12 is installed on the mounting plate assembly 11 around the smoking port 101, and a smoke collecting chamber is formed in the smoke hood 12. The oil smoke generated by the stove flows into the smoke collecting chamber of the smoke hood 12 through the smoking pipe 20 and the smoking port 101. The smoke hood 12 gradually shrinks toward the bottom of the stove to form a smoke collecting port connected to the fan. The oil smoke entering the smoke collecting chamber flows into the fan through the smoke collecting port, and then is discharged out of the stove through the exhaust pipe on the fan.

[0055] In this embodiment, the smoking device 100 can drive the smoking tube 20 to rise and fall at the smoking port 101 through the lifting mechanism, so as to improve the user experience of the combined device with the smoking device and the stove. The combined device with the smoking device and the stove has all the technical effects of the smoking device 100, which will not be described in detail here. Further, the shape of the smoking port 101 matches the shape of the smoking tube 20 of the smoking device 100. For example, the smoking tube 20 and the smoking port 101 can be set as a rectangular structure, or can be set as a circle or an ellipse. The number of smoking devices 100 is not limited to one. When the area between the gas stoves is large enough and the size of the smoking port 101 is large enough, two or more smoking devices 100 can be set at the smoking port 101, and the number of smoking tubes 20 raised can be reasonably controlled according to the use of the gas stove. In addition, the above embodiment only describes the relevant structures in the combined device with the smoking device and the stove, and does not mean that the combined device with the smoking device and the stove only includes the above structure. Other structures in the combined device with the smoking device and the stove are not described in detail here.
