[0002] Combustion devices generate combustion products by burning materials to meet user needs. During use, these combustion products typically need to be filtered before being used, while combustion residues remain in the combustion chamber. With repeated use, the accumulation of these residues may affect the product's continued performance.

[0003] In related technologies, the use of combustion devices typically involves multiple stages, including material supply, combustion, and ash removal. The efficiency of coordination between these stages and the ease of use need further improvement. Summary of the Invention

[0027] The technical solutions of this disclosure will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] See Figures 1 to 24 As shown, this embodiment of the present disclosure provides a combustion device, including a drive mechanism 10, a first switching element 30, a second switching element 40, and a combustion chamber 20; the power output shaft of the drive mechanism 10 includes a first output shaft 11 and a second output shaft 12; the first output shaft 11 is drivenly connected to the first switching element 30, and the second output shaft 12 is drivenly connected to the second switching element 40; the first switching element 30 is located below the combustion chamber 20 and is provided with an ash bin 31 and an outlet channel 32; the second switching element 40 is located above the combustion chamber 20 and is provided with a feed channel 41 and an air intake channel 42; the combustion device has a feeding state, a combustion state, and an ash discharge state. In the feeding state, the feeding channel 41 is connected to the combustion chamber 20 to allow material to enter the combustion chamber 20; in the combustion state, the air intake channel 42 is connected to the combustion chamber 20 to allow outside air to enter the combustion chamber 20, and the exhaust channel 32 is connected to the combustion chamber 20 to allow combustion releases generated by the combustion of material in the combustion chamber 20 to be discharged from the exhaust channel 32; in the ash discharge state, the ash hopper 31 is connected to the combustion chamber 20 to allow combustion residues generated by combustion to fall into the ash hopper 31; the power output shaft of the drive mechanism 10 can rotate in a first direction or in a second direction to switch the combustion device between the feeding state, the combustion state and the ash discharge state, wherein the first direction and the second direction are opposite.

[0031] The combustion device provided in this embodiment utilizes the first output shaft 11 and the second output shaft 12 of the drive mechanism 10 to drive the first switching member 30 and the second switching member 40 to move, enabling the combustion device to switch between a feeding state, a combustion state, and an ash discharge state. In the feeding state, the feeding channel 41 is connected to the combustion chamber 20 to transport materials to the combustion chamber 20; in the combustion state, the air intake channel 42 is connected to the combustion chamber 20 to allow outside air to enter the combustion chamber 20, which helps the material to burn, while the exhaust channel 32 is connected to the combustion chamber 20, allowing the combustion release products generated during combustion to be discharged from the exhaust channel 32 and used by the user; in the ash discharge state, the ash hopper 31 is connected to the combustion chamber 20, and the combustion residue generated after combustion is discharged into the ash hopper 31 to reduce the accumulation of residue in the combustion chamber 20 and improve the continuous use performance of the product. The combustion device provided in this embodiment drives the first switching element 30 and the second switching element 40 to move relative to the combustion chamber 20 through the same driving mechanism 10, thereby realizing the switching of multiple states (feeding state, combustion state and ash discharge state). This is beneficial to improve the coordination efficiency between various links, simplify the product operation process, improve the overall working efficiency of the product, and enhance its ease of use and fluency.

[0032] It should be understood that the drive mechanism 10 in this embodiment can be a dual-shaft extension motor, and the "transmission connection" includes direct transmission connection and indirect transmission connection; wherein, indirect transmission connection refers to transmission connection realized through one or more intermediate transmission components. In addition, in this embodiment, one of the first direction and the second direction is clockwise, and the other is counterclockwise.

[0033] It should be understood that the directional descriptions such as "above" and "below" in the embodiments of this disclosure are based on the relative positional relationship when the combustion device is in normal use. The above directional descriptions are only used to facilitate the explanation of the structural relationships in the embodiments of this disclosure, and should not be construed as limiting the embodiments of this disclosure.

[0034] See Figures 4 to 6 , Figure 17 As shown, in some embodiments, the combustion chamber 20 has a tubular structure with a first end and a second end disposed opposite to each other, the first end being located above the second end, wherein the first end is close to the second switching member 40 and the second end is close to the first switching member 30.

[0035] See Figure 6 and Figure 12As shown, in some embodiments, the combustion device further includes a filter assembly 50, which includes a filter element that is generally cylindrical, such as a cylinder. The filter assembly 50 is installed on the first switching member 30 and spaced apart from the ash hopper 31. The filter assembly 50 is connected to the outlet channel 32 so that the combustion releases generated by the combustion of materials in the combustion chamber 20 pass through the filter assembly 50 and enter the outlet channel 32. The first switching member 30 has a filtration station and an ash discharge station, and the second switching member 40 has a feeding station and an air intake station. The first output shaft 11 can drive the first switching member 30 to switch between the filtration station and the ash discharge station, and the second output shaft 12 can drive the second switching member 40 to switch between the feeding station and the air intake station. See also... Figure 6 As shown, in the feeding state, the first switching element 30 is in the filtering position, and the second switching element 40 is in the feeding position; see also Figure 9 As shown, in the combustion state, the first switching element 30 is in the filtering position, and the second switching element 40 is in the intake position; see also Figure 12 As shown, in the ash discharge state, the first switching component 30 is in the ash discharge station, and the second switching component 40 is in the air intake station.

[0036] By setting a filter assembly 50 and an ash bin 31 in the first switching unit 30, and setting the filter assembly 50 and the ash bin 31 at intervals, when the first switching unit 30 is in the filtration station, the combustion releases generated by the combustion chamber 20 can be filtered through the filter element of the filter assembly 50 and enter the outlet channel 32, thereby improving the quality of the combustion releases; when the first switching unit 30 is switched to the ash discharge station, the ash bin 31 is connected to the combustion chamber 20, so that the combustion residues generated by combustion are discharged into the ash bin 31, realizing the separation of the filtration and ash discharge functions of combustion releases, which helps to reduce the impact of combustion residues on the filter assembly 50.

[0037] It should be understood that in this embodiment, the filter assembly 50 and the ash bin 31 are integrated into the first switching component 30, and correspond to the filtration station and the ash discharge station respectively. The switching between the filtration function and the ash discharge function can be realized without the need for separate switching mechanisms for the filter assembly 50 and the ash bin 31. This is beneficial for simplifying the structure and improving space utilization, as well as for product miniaturization and portable design.

[0038] By switching between the filtration and ash removal stations using the first switching element 30, and between the feeding and air intake stations using the second switching element 40, the material supply, combustion, and ash removal processes are switched and integrated in an orderly manner, enabling the combustion device to switch between different operating states. Specifically, in the feeding state, the first switching element 30 is in the filtration station, with the filter assembly 50 located below the combustion chamber 20, and the second switching element 40 is in the feeding station, with the feeding channel 41 connected to the combustion chamber 20. At this time, the material enters the combustion chamber 20 and falls above the filter assembly 50. In the combustion state, the material burns within the combustion chamber 20. The first switching element 30 is in the filtration station, and the second switching element 40 is in the air intake station, with the air intake channel 42 connected to the combustion chamber 20, allowing outside air to enter the combustion chamber 20, which aids in material combustion. The combustion releases produced by combustion are filtered by the filter assembly 50 and discharged from the outlet channel 32 for user use. In the ash discharge state, the first switching component 30 is in the ash discharge position, and the ash hopper 31 is connected to the combustion chamber 20, so that the combustion residues produced by combustion are discharged into the ash hopper 31, realizing the separation of the combustion release filtration and ash discharge functions, which helps to reduce the impact of combustion residues on the filter assembly 50. The second switching component 40 is in the air intake position, which can prevent fresh materials from being directly discharged from the feed channel 41 into the ash hopper 31 and causing waste.

[0039] In some embodiments, the combustion device further includes an automatic ignition device, see [link to documentation]. Figure 9 and Figure 13 As shown, the automatic ignition device includes at least one electrode 210. The electrode 210 is mounted on the circumferential sidewall of the combustion chamber 20. It should be noted that the structure and working principle of the automatic ignition device should be understandable to those skilled in the art, and are well known and easily implemented by those skilled in the art; therefore, this embodiment will not describe it in detail.

[0040] The combustion device provided in this disclosure is a universally adaptable device that can achieve combustion and release of different types of materials. By configuring different adaptable components and modular design, it can realize different application scenarios, meet the application needs of different materials, and improve the universality, compatibility and application expansion capability of the device.

[0041] See Figure 1 , Figure 3 and Figure 9As shown, in some embodiments, the combustion device further includes a housing 190 and a release part 200, both of which can serve as adapter components. The drive mechanism 10, the first switching element 30, the second switching element 40, the combustion chamber 20, the filter assembly 50, the ash bin 31, and the automatic ignition device are all installed within the housing 190. The release part 200 is connected to the housing 190 and communicates with the outlet channel 32. It should be noted that the release part 200 and the outlet channel 32 are connected via a pipeline (not shown in the figure), and the housing 190 is provided with an outlet pipe connector 180 for connecting to the pipeline.

[0042] In some embodiments, the release part 200 is rotatably connected to the housing 190, and the housing 190 is provided with a storage groove, so that the release part 200 can be rotated into the storage groove when not in use. In other embodiments, the release part 200 is detachably connected to the housing 100.

[0043] In some embodiments, the combustion device can be applied to the field of smoking devices, for example, to achieve the combustion treatment of tobacco materials and the release of smoke. In this application scenario, the release unit 200 may include a mouthpiece to allow a user to obtain the treated gas. The user inhales the released material filtered by the filter assembly 50 through the mouthpiece.

[0044] In other embodiments, the combustion device can also be applied to the fragrance industry, for example, to achieve the combustion treatment and fragrance release of woody materials, aromatic herbal materials (such as artemisia), floral materials, plant resin materials, and plant-derived composite materials. In this application scenario, the release unit 200 may include a release cover with at least one vent hole to allow the fragrance generated by combustion to diffuse outward.

[0045] It should be understood that the specific application areas of the combustion device are not limited to the two mentioned above. Depending on different application requirements, the outer casing 190, the release unit 200, and other adaptable components of the combustion device can be adaptively adjusted to suit different types of materials and application scenarios. The overall appearance of the combustion device can be the same or different in different application areas.

[0046] It should be noted that the combustion releases described in the embodiments of this disclosure include, but are not limited to, mixtures of components such as gases and volatile substances. For example, combustion releases may include smoke components produced by tobacco combustion, odor components produced by the combustion of aromatherapy materials, or release components produced by the combustion of other combustibles.

[0047] The filtered releases described in this embodiment typically refer to the residual components formed after combustion releases are filtered by a filter element or filter assembly, with some components being retained. These components mainly include, but are not limited to, gaseous components such as smoke and aroma. The filtered releases are available for use by the user.

[0048] The combustion residues mentioned in this embodiment refer to non-volatile solid or semi-solid substances remaining in the combustion chamber and other related structures after the material has been burned in the combustion chamber, including but not limited to ash (such as soot, incense ash, etc.), unburned material residues, tar or coking matter, and inorganic residues produced by high-temperature reactions.

[0049] It should be understood that, for different materials (such as tobacco or aromatherapy materials), those skilled in the art can adjust the airflow of the gas supply device 150 and the combustion temperature of the combustion chamber 20 according to their combustion characteristics, which are all within the scope of protection of this disclosure.

[0050] In some embodiments, a mounting base (not shown in the figure) is provided inside the housing 190, and the mounting base is provided with a shaft hole, and the rotating shaft 35 is engaged with the shaft hole.

[0051] In this embodiment, the combustion chamber 20 is fixed relative to the outer casing 190. The first switching element 30 and the second switching element 40 are located below and above the combustion chamber 20, respectively, and the switching of feeding, combustion, and ash discharge states is achieved by switching the positions of the first switching element 30 and the second switching element 40. Since the combustion chamber 20 remains fixed during operation and does not need to move with the switching of working states, it can reduce moving parts, simplify the structural design, reduce the driving load, and shorten the response time of the switching action. At the same time, it can avoid the combustion chamber 20 from reciprocating in the high-temperature working environment, which is beneficial to improving the safety of the use process. The relative position between the combustion chamber 20 and the automatic ignition device remains stable, which is beneficial to maintaining the stability of the combustion process and improving the working reliability and state switching efficiency of the product.

[0052] It should be understood that this disclosure does not limit the structure and specific arrangement of the filter assembly 50. The filtration function can be achieved by the filter assembly 50 disposed on the first switching member 30, by the filter structure disposed at the release part 200, or by other filter components disposed on the combustion release material circulation path. For example, in a scheme where the release part 200 includes a mouthpiece, the filter structure can be disposed within the release part 200, and the release part can be a filter mouthpiece. The combustion release material generated during combustion enters the filter mouthpiece after passing through the outlet channel 32 and is filtered. In this case, the filtration function is achieved by the filter mouthpiece, thus eliminating the need to provide the filter assembly 50 on the first switching member 30. As another example, in a scheme where the release part 200 includes a release cover, a filter element can be disposed inside the release cover.

[0053] See Figure 4 and Figure 6 As shown, in some embodiments, the combustion device further includes a first one-way clutch mechanism 80 and a second one-way clutch mechanism 90. The first output shaft 11 is drivenly connected to the first switching member 30 through the first one-way clutch mechanism 80; the second output shaft 12 is drivenly connected to the second switching member 40 through the second one-way clutch mechanism 90. The drive mechanism 10 is configured such that when the power output shaft rotates in a first direction, the first one-way clutch mechanism 80 is in a driving state to enable the first switching member 30 to switch positions, and the second one-way clutch mechanism 90 is in an idling state to enable the second switching member 40 to remain in the current position; when the power output shaft rotates in a second direction, the first one-way clutch mechanism 80 is in an idling state to enable the first switching member 30 to remain in the current position, and the second one-way clutch mechanism 90 is in a driving state to enable the second switching member 40 to switch positions.

[0054] By setting up a first one-way clutch mechanism 80 and a second one-way clutch mechanism 90, the power output shaft of the drive mechanism 10 can selectively drive different switching elements when rotating in different directions. During the power output process of the drive mechanism 10, it avoids the simultaneous action of one switching element and the other, thus achieving selective switching of the first switching element 30 and the second switching element 40, as well as position holding, which helps improve the control reliability and stability during the switching process of various working states. When the power output shaft rotates along the first direction, the first output shaft 11 and the second output shaft 12 rotate simultaneously along the first direction. The first one-way clutch mechanism 80 is in the transmission state and drives the first switching member 30 to switch positions, while the second one-way clutch mechanism 90 is in the idling state to cut off the power transmission between the second output shaft 12 and the second switching member 40, so that the second switching member 40 remains in the current position. When the power output shaft rotates along the second direction, the first output shaft 11 and the second output shaft 12 rotate simultaneously along the second direction. The second one-way clutch mechanism 90 is in the transmission state and drives the second switching member 40 to switch positions, while the first one-way clutch mechanism 80 is in the idling state to cut off the power transmission between the first output shaft 11 and the first switching member 30, so that the first switching member 30 remains in the current position. Therefore, the first switching element 30 and the second switching element 40 can be independently controlled using the same drive mechanism 10, without the need to configure a separate drive source for each switching element. This simplifies the transmission structure, reduces the number of parts, and ensures a simpler and more compact overall structure. It also helps to reduce costs and control complexity, and improves the reliability and response speed of workstation switching.

[0055] In some embodiments, the first one-way clutch mechanism 80 in the combustion device is a first one-way bearing, and the second one-way clutch mechanism 90 in the combustion device is a second one-way bearing.

[0056] It should be noted that this disclosure does not limit the specific structural form of the first one-way clutch mechanism 80 and the second one-way clutch mechanism 90. In some embodiments, it can be implemented using a one-way bearing; in other embodiments, it can also be implemented using other mechanisms capable of achieving one-way transmission and reverse idling. Any mechanism that can transmit power in one direction of rotation and disengage transmission in the opposite direction of rotation can be used as the first one-way clutch mechanism 80 and the second one-way clutch mechanism 90 in this disclosure.

[0057] See Figure 6 , Figure 12 , Figure 15 and Figure 16 As shown, in some embodiments, the first switching member 30 is provided with a first placement cavity 331 and a second placement cavity 341, the first placement cavity 331 and the second placement cavity 341 are arranged circumferentially at intervals around a set axis, the ash bin 31 is installed in the first placement cavity 331, and at least a portion of the filter assembly 50 is installed in the second placement cavity 341.

[0058] See Figure 6 , Figure 12 , Figure 15 and Figure 16 As shown, exemplarily, the first switching member 30 is generally fan-shaped and has a rotating shaft 35, the axis of which can be a predetermined axis. The first placement cavity 331 and the second placement cavity 341 can be cylindrical, for example, cylindrical, with their openings facing the combustion chamber 20; the ash bin 31 is also cylindrical, with its opening facing the combustion chamber 20, and is detachably mounted in the first placement cavity 331; along the axial direction of the first placement cavity 331, the filter assembly 50 can be entirely located within the second placement cavity 341, or partially located within the second placement cavity 341 and partially located outside the second placement cavity 341. When the first switching member 30 rotates around the predetermined axis, it can cause the positions of the first placement cavity 331 and the second placement cavity 341 to change, so that the ash bin 31 and the filter assembly 50 alternately communicate with the combustion chamber 20.

[0059] It should be understood that the small gap between the first placement cavity 331 and the second placement cavity 341 is beneficial for achieving rapid switching between the filter assembly 50 and the ash bin 31.

[0060] It should be noted that the shape of the first switching element 30 is not limited to a fan shape; other shapes of the first switching element 30 can also be selected according to actual needs. The filter assembly 50 is detachably installed in the second placement cavity 341, facilitating the replacement of the filter assembly 50.

[0061] See Figure 12As shown, in some embodiments, the combustion device further includes a buffer 140, which is installed between the bottom plate of the ash bin 31 and the bottom wall of the first placement cavity 331. For example, the buffer 140 can be a compression spring, providing elastic support to the ash bin 31, ensuring that the open end face of the ash bin 31 can fit against the end face of the second end of the combustion chamber 20, ensuring that combustion residue falls into the ash bin 31, and reducing the risk of combustion residue being discharged from the gap between the combustion chamber 20 and the ash bin 31.

[0062] See Figure 9 and Figure 15 As shown, in some embodiments, the first switching element 30 includes a first sub-base 33 and a second sub-base 34, the first sub-base 33 and the second sub-base 34 are fixedly connected, and the first sub-base 33 and the second sub-base 34 together define a flow channel, which forms at least a portion of the outlet channel 32; the ash bin 31 is disposed on the first sub-base 33, and the filter assembly 50 is disposed on the second sub-base 34.

[0063] For example, the first sub-base 33 and the second sub-base 34 have a fan-shaped plate structure. The first placement cavity 331 is integrally formed with the first sub-base 33, and the second placement cavity 341 is integrally formed with the second sub-base 34. The second sub-base 34 is provided with a clearance portion to avoid the first placement cavity 331. After the second sub-base 34 is connected to the lower part of the first sub-base 33, the first placement cavity 331 and the second placement cavity 341 are arranged circumferentially spaced about a set axis.

[0064] In a first possible design, the lower surface of the first sub-base 33 is provided with a first groove, and the first groove and the surface of the second sub-base 34 covering the opening of the first groove together define a flow channel.

[0065] In a second possible design, the upper surface of the second sub-base 34 is provided with a second groove, and the second groove and the surface of the first sub-base 33 covering the opening of the second groove together define a flow channel.

[0066] In the third possible design, the lower surface of the first sub-base 33 is provided with a first groove, and the upper surface of the second sub-base 34 is provided with a second groove. The first groove and the second groove are staggered. The first groove and the surface of the second sub-base 34 covering the opening of the first groove together define a first flow channel. The second groove and the surface of the first sub-base 33 covering the opening of the second groove together define a second flow channel. The first flow channel and the second flow channel are connected, and the first flow channel and the second flow channel together form a flow channel.

[0067] In the fourth possible design, the lower surface of the first sub-base 33 is provided with a first groove, and the upper surface of the second sub-base 34 is provided with a second groove. The openings of the first groove and the second groove are opposite to each other. In this case, the first groove and the second groove together define a flow channel.

[0068] See Figure 6 , Figure 14 and Figure 16 As shown, in some embodiments, the combustion device further includes a first eccentric wheel 100, a first switching member 30 is provided with a guide groove 36, and the first eccentric wheel 100 cooperates with the guide groove 36; the first output shaft 11 is connected to the first eccentric wheel 100 for transmission, so as to drive the first switching member 30 to rotate around a set axis through the first eccentric wheel 100.

[0069] See Figure 6 , Figure 13 and Figure 14 As shown, along the axial direction of the first eccentric wheel 100, the first eccentric wheel 100 is at least partially installed within the guide groove 36. This reduces the space occupied by the first eccentric wheel 100, which is beneficial for product miniaturization and portable design. The guide groove 36 has two opposing first inner walls 361, the distance between which is adapted to the diameter of the first eccentric wheel 100, and the outer peripheral surface of the first eccentric wheel 100 contacts the two first inner walls 361. The first output shaft 11 of the drive mechanism 10 is connected to the eccentric shaft of the first eccentric wheel 100. When the drive mechanism 10 drives the eccentric wheel to rotate, the outer peripheral surface of the first eccentric wheel 100 makes an eccentric movement between the two first inner walls 361 of the guide groove 36, which can smoothly drive the first switching member 30 to switch between the filtration station and the ash discharge station.

[0070] See Figure 13 and Figure 16 As shown, in some embodiments, the combustion device further includes a limiting mechanism 110, which includes a limiting post 111 and an arc-shaped limiting hole 112. The limiting post 111 is connected to the power output shaft of the drive mechanism 10, and the axis of the limiting post 111 coincides with the axis of the first output shaft 11. The center of the arc-shaped limiting hole 112 is located on a set axis. The limiting mechanism 110 uses the hole walls at both ends of the arc-shaped limiting hole 112 to abut against the limiting post 111 to achieve mechanical limiting of the first switching member 30, providing a limiting constraint for the rotation of the first switching member 30. At the same time, the arc-shaped limiting hole 112, in cooperation with the guide post, can also play an auxiliary guiding role, share the force load of the first output shaft 11, improve the smoothness of the rotation of the first switching member 30, improve the station switching efficiency, and enhance the operational safety and service life of the overall mechanism.

[0071] See Figure 6 and Figure 17 and Figure 18 As shown, in some embodiments, the feed channel 41 and the air intake channel 42 are along a third direction (within the third direction). Figure 18(The arrow X in the image indicates the direction of the interval) The combustion device also includes a guide mechanism 120 and a second eccentric wheel 130, the second eccentric wheel 130 being mounted on the second switching member 40; the second output shaft 12 is capable of driving the second eccentric wheel 130 to rotate, and the guide mechanism 120 and the second switching member 40 are guided and cooperated so that the second switching member 40 can reciprocate along a third direction.

[0072] See Figure 17 As shown, the second switching member 40 is provided with a recess 43, and the second eccentric wheel 130 is installed in the recess 43. This reduces the space occupied by the second eccentric wheel 130, which is beneficial for product miniaturization and portable design. Along the first direction, the recess 43 has two opposing second inner walls 431. The distance between the two second inner walls 431 is adapted to the diameter of the second eccentric wheel 130, and the outer peripheral surface of the second eccentric wheel 130 contacts the two second inner walls 431. The second output shaft 12 of the drive mechanism 10 is connected to the eccentric shaft of the second eccentric wheel 130. When the drive mechanism 10 drives the second eccentric wheel 130 to rotate, the outer peripheral surface of the second eccentric wheel 130 makes an eccentric movement between the two second inner walls 431 of the recess 43. With the guidance of the guide mechanism 120, the second switching member 40 can be smoothly driven to switch between the feeding station and the air intake station.

[0073] See Figure 6 , Figure 9 , Figure 19 and Figure 20 As shown, in some embodiments, the combustion device further includes a base 60 having a receiving cavity 61, a second switching member 40 located within the receiving cavity 61, and a combustion chamber 20 fixedly connected to the base 60.

[0074] See Figure 17 As shown, in some embodiments, the guide mechanism 120 includes a guide shaft 121 and a bushing 122. The guide shaft 121 is fixedly connected to the base 60, and the axis of the guide shaft 121 is parallel to a third direction. The second switching member 40 is provided with a guide channel, and the bushing 122 is fixedly installed in the guide channel. The bushing 122 is sleeved on the guide shaft 121, and the bushing 122 can reciprocate along the axis of the guide shaft 121.

[0075] See Figure 19As shown, for example, the base 60 is provided with two opposing slots 62, and the two ends of the guide shaft 121 are respectively limited and fixed in the corresponding slots 62. The cross-sectional shape of the guide channel can be circular, and the bushing 122 can be interference-fitted with the guide channel. The bushing 122 can also be fixedly connected to the second switching member 40 by fasteners, wherein the fasteners can include bolts and nuts. When the drive mechanism 10 drives the second eccentric wheel 130 to rotate, the bushing 122 can reciprocate along the axis of the guide shaft 121, thereby guiding the movement of the second switching member 40 and ensuring that the second switching member 40 can reciprocate along the first direction, thereby switching between the feeding station and the air intake station.

[0076] In other embodiments, the bushing 122 may also be integrally formed with the second switching element 40.

[0077] It should be noted that the form of the guide mechanism 120 is not limited to the one mentioned above. As long as the guide mechanism 120 can play a guiding role and ensure that the second switching component 40 switches between the feeding station and the air intake station, it falls within the protection scope of this disclosure.

[0078] See Figure 3 , Figure 8 , Figure 9 and Figure 20 As shown, in some embodiments, the combustion device further includes a gas supply device 150, which supplies airflow to the combustion chamber 20 when the combustion device is in combustion mode. The gas supply device 150 includes an air pump, its air inlet is connected to outside air, and its air outlet is connected to the air inlet channel 42. In combustion mode, the gas supply device 150 continuously introduces outside air into the combustion chamber 20, which is beneficial for material combustion. In ash discharge mode, the gas supply device 150 can be shut off, eliminating the need to introduce outside air into the combustion chamber 20.

[0079] In other embodiments, the air supply device 150 may also include a fan, such as, but not limited to, a traditional fan. The fan's air inlet is in communication with ambient air, and the fan's air outlet is in communication with the air inlet passage 42.

[0080] In some embodiments, the air supply device 150 further includes an air supply pipeline (not shown in the figure), through which ambient air, under the action of an air pump, enters the combustion chamber 20 via the air supply pipeline and the air intake passage 42, thereby improving the combustion efficiency of the material in the combustion chamber 20. See also Figure 3 and Figure 9 As shown, the base 60 is provided with an air inlet pipe connector 65, and the air supply pipeline is connected to and communicates with the air inlet pipe connector 65.

[0081] See Figure 17As shown, in some embodiments, the second switching element 40 has a first notch and a second notch on its side wall near the combustion chamber 20. The first notch forms a feed channel 41, and the second notch is a groove with a vent hole on its inner wall, forming an air intake channel 42. This allows for the integrated design of the air intake channel 42, the feed channel 41, and the second switching element 40, which simplifies the internal structure of the combustion device, reduces the number of parts, and also reduces the weight of the second switching element 40 by providing the first and second notches, thus facilitating the miniaturization and portability of the product.

[0082] See Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figures 22 to 24 As shown, in some embodiments, the combustion device further includes a cleaning device 70, which includes a mounting base 71, a connecting pipe 72, and a cleaning part 73. The mounting base 71 is mounted above the combustion chamber 20 and has a through hole for the cleaning part 73 to pass through. One end of the connecting pipe 72 is fixedly connected to the mounting base 71, and the other end of the connecting pipe 72 is located inside the combustion chamber 20. The connecting pipe 72 communicates with the through hole and has a connecting part 721. A first notch and a second notch communicate with the combustion chamber 20 through the connecting part 721, respectively. The cleaning part 73 is mounted on the mounting base 71, and at least a portion of the cleaning part 73 can move into the combustion chamber 20 and contact the inner wall of the combustion chamber 20.

[0083] See Figure 6 As shown, in some embodiments of this disclosure, the connecting pipe 72 includes a first pipe segment 722 and a second pipe segment 723. The end of the first pipe segment 722 away from the second pipe segment 723 is fixedly connected to the mounting base 71. The end of the second pipe segment 723 away from the first pipe segment 722 is located inside the combustion chamber 20. The first pipe segment 722 and the second pipe segment 723 are spaced apart. The connecting portion 721 includes an open portion formed by the spaced interval between the first pipe segment 722 and the second pipe segment 723.

[0084] See Figure 6 As shown, in some embodiments of this disclosure, the connecting portion 721 may also be an opening provided with the side wall of the connecting pipe 72.

[0085] See Figure 6 , Figure 8 and Figure 19As shown, in some embodiments, the inner wall of the combustion chamber 20 is provided with a first limiting boss 21, and the lower surface of the base 60 is provided with a second limiting boss 63. The two ends of the second pipe section 723 abut against the first limiting boss 21 and the second limiting boss 63 respectively to achieve sealing, ensuring that the combustion release generated in the combustion chamber 20 can enter the outlet channel 32 and will not escape from other places (such as between the second pipe section 723 and the combustion chamber 20).

[0086] See Figure 5 As shown, when the material burns within the combustion chamber 20, the cleaning section 73 is located outside the combustion chamber 20; exemplarily, the cleaning section 73 is located on the side of the second switching member 40 furthest from the combustion chamber 20. See also... Figure 12 As shown, when it is necessary to clean the combustion residue in the combustion chamber 20, at least a portion of the cleaning part 73 can be moved into the combustion chamber 20 by electric drive and come into contact with the inner wall of the combustion chamber 20. It should be understood that from the moment the cleaning part 73 comes into contact with the inner wall of the first end of the combustion chamber 20 until the cleaning part 73 comes into contact with the inner wall of the second end of the combustion chamber 20, the portion of the cleaning part 73 that comes into contact with the inner wall of the combustion chamber 20 is considered to be located inside the combustion chamber 20.

[0087] The mounting base 71 and the base 60 can be installed separately or integrally formed.

[0088] See Figures 22 to 24 As shown, in some embodiments, the cleaning device 70 further includes a first drive member 74, a first gear 75, a second gear 76, and a second drive member 77. The first drive mechanism 10 is connected to the first gear 75, and the first gear 75 meshes with the second gear 76. The axial length L1 of the first gear 75 is greater than the axial length L2 of the second gear 76. The second gear 76 is connected to the cleaning part 73 to drive the cleaning part 73 to rotate around the axis of the second gear 76. The second drive mechanism 10 is connected to the second gear 76 to drive the second gear 76 and the cleaning part 73 to reciprocate along the axial direction of the first gear 75. The cleaning part 73 is used to contact the inner wall of the combustion chamber 20 of the combustion device.

[0089] When cleaning combustion residue in the combustion chamber 20, the first drive mechanism 10 drives the first gear 75 to rotate, the first gear 75 drives the second gear 76 to rotate, and in turn drives the cleaning part 73 to rotate around the axis of the second gear 76. The cleaning part 73 can contact the inner wall of the combustion chamber 20 of the combustion device and clean the inner wall. Since the axial length of the first gear 75 is greater than the axial length of the second gear 76, the second drive mechanism 10 drives the second gear 76 and the cleaning part 73 to reciprocate along the axis of the first gear 75 together, while keeping the second gear 76 meshing with the first gear 75, thereby ensuring that the cleaning part 73 can thoroughly clean the combustion chamber 20.

[0090] See Figures 22 to 24 As shown, the cleaning device 70 also includes a lead screw 781 and a nut 782. A second drive member 77 is connected to the lead screw 781, and the nut 782 is threadedly connected to the lead screw 781. The nut 782 is fixedly connected to the cleaning part 73. The second drive member 77 can drive the lead screw 781 to rotate around its own axis, thereby driving the nut 782 to reciprocate along the axial direction of the lead screw 781. The movement and stopping position of the cleaning structure 732 are precisely controlled by the lead screw 781, ensuring that the cleaning part 73 thoroughly cleans the interior of the combustion chamber 20. At the same time, when cleaning is not required, for example, when the material is burning, the cleaning part 73 is located outside the combustion chamber 20.

[0091] See Figure 22 and Figure 24 As shown, in some embodiments, the cleaning device 70 further includes a connecting frame 79, through which the nut 782 and the cleaning part 73 are fixedly connected. Exemplarily, the circumferential outer surface of the nut 782 is provided with anti-rotation knurling. A riveting process is used to deeply engage the knurled structure with the connecting frame 79, thereby fixing the nut 782 on the connecting frame 79. The anti-rotation knurling enhances the friction and mechanical shear resistance between the nut 782 and the connecting frame 79, ensuring that the nut 782 will not undergo circumferential displacement or rotation when the second drive component 77 outputs high torque or frequently starts and stops, thus improving the reliability of the transmission chain.

[0092] See Figure 5 and Figure 12 As shown, in some embodiments, the cleaning section 73 includes a rotating rod 731 and a cleaning structure 732. The rotating rod 731 passes through a through hole, and the cleaning structure 732 is connected to the rotating rod 731. The cleaning structure 732 has an initial working position and a cleaning working position. In the initial working position, the cleaning structure 732 is located on the side of the connecting section 721 away from the combustion chamber 20. In the cleaning working position, the cleaning structure 732 is located inside the combustion chamber 20.

[0093] One end of the rotating rod 731 is fixedly connected to the second gear 76, enabling stable power transmission. Using the rotating rod 731 as a transitional connection between the second gear 76 and the cleaning structure 732 helps shorten the length of the cleaning structure 732, reducing the overall weight of the cleaning device 70 and lowering production costs. When cleaning the inner wall of the combustion chamber 20, the cleaning structure 732 contacts the inner wall while the rotating rod 731 does not, reducing frictional resistance during the movement of the cleaning part 73 and facilitating smooth reciprocating motion of the cleaning part 73 along the axial direction of the first gear 75.

[0094] See Figures 22 to 24As shown, the cleaning structure 732 includes a brush, which can be made of, but is not limited to, metal. For example, the brush handle can be integrally formed with the rotating rod 731, enhancing the overall structural strength of the cleaning unit 73 and preventing the risk of brush detachment due to mechanical fatigue during high-frequency rotation or reciprocating motion, thus improving the reliability of the cleaning device 70. The brush uses copper bristles, utilizing the high-temperature resistance and corrosion resistance of copper to maintain good mechanical properties even in the complex chemical environment of the combustion chamber 20. Furthermore, since the combustion chamber 20 is typically made of ceramic, and copper is less hard than ceramic, using copper bristles not only effectively removes combustion residues adhering to the inner wall of the combustion chamber 20 but also effectively protects the inner wall of the combustion chamber 20 from scratches, extending the service life of the combustion chamber 20.

[0095] See Figure 23 As shown, in other embodiments, the cleaning structure 732 may also include a scraper (such as...). Figure 12 As shown, the scraper can be made of, but is not limited to, rubber.

[0096] It should be noted that at least a portion of the cleaning unit 73 can also be moved manually into the combustion chamber 20 and brought into contact with the inner wall of the combustion chamber 20 to remove combustion residues from the combustion chamber 20.

[0097] By setting up the cleaning device 70, the combustion residue after combustion can be discharged in a timely manner, which helps to maintain the working condition of the combustion chamber 20, improve the overall working efficiency of the product and the user experience.

[0098] See Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, in some embodiments, the combustion device further includes a feed chamber 160, which is located above the combustion chamber 20, and a second switching element 40 is located between the feed chamber 160 and the combustion chamber 20. When the combustion device is in the feeding state, one end of the feed channel 41 is connected to the outlet of the feed chamber 160, and the other end of the feed channel 41 is connected to the combustion chamber 20, so that the material in the feed chamber 160 enters the combustion chamber 20. When the combustion device is in the combustion state, the second switching element 40 blocks the outlet of the feed chamber 160, and the air intake channel 42 is connected to the combustion chamber 20.

[0099] In the feeding state, the material enters the combustion chamber 20 through the feeding chamber 160 and the feeding channel 41. At this time, the air supply device 150 is usually in the closed state. In the combustion state, the air supply device 150 is turned on, and the air supply device 150 supplies outside air to the combustion chamber 20 through the air intake channel 42. At this time, the feeding channel 41 and the outlet of the feeding chamber 160 are misaligned, and the outlet of the feeding chamber 160 is blocked by the upper surface of the second switching member 40, cutting off the passage between the feeding chamber 160 and the combustion chamber 20, and preventing the material in the feeding chamber 160 from continuing to fall and causing waste.

[0100] The feed chamber 160 is located above the combustion chamber 20. The material can fall into the combustion chamber 20 under its own gravity or be pushed into the combustion chamber 20 by an external force.

[0101] See Figure 2 and Figure 5 As shown, in some embodiments, a screw feeder 170 is provided inside the feed chamber 160. The screw feeder 170 includes a rotating shaft and screw blades. The screw blades are disposed on the circumferential sidewall of the rotating shaft, which can rotate around its own axis, so that the screw blades can carry the material to the discharge port of the feed chamber 160. When the material enters the feed port of the feed chamber 160, it will fall onto the screw blades of the screw feeder 170. Since the rotating shaft of the screw feeder 170 can rotate around its own axis, the screw blades carry the material along with it, thereby conveying the material to the discharge port of the feed chamber 160, reducing the risk of material adhering to the inner wall of the feed chamber 160, and thus reducing the risk of material jamming during the feeding process.

[0102] In some embodiments, the edge of the helical blade is clearance-fitted with the inner wall of the feed cylinder, which reduces shearing and compression of the material and decreases frictional wear between the helical blade and the inner wall of the feed cylinder. For example, the gap between the edge of the helical blade and the inner wall of the feed cylinder is smaller than the particle size of the material, reducing the risk of material getting stuck between the helical blade and the inner wall of the feed cylinder.

[0103] In some embodiments, the screw feeder 170 is inclined, that is, the axis of the rotating shaft 35 of the screw feeder 170 is set at an angle to the axis of the connecting pipe 72. The first notch is an oblique opening, which is substantially parallel to the extension direction of the rotating shaft 35; the discharge port of the discharge pipe is offset from the combustion chamber 20, and the material falls smoothly onto the inclined surface of the oblique opening through the discharge port, and falls into the combustion chamber 20 through the connecting part 721.

[0104] In other embodiments, the screw feeder 170 may also be arranged vertically. Accordingly, the discharge port of the discharge pipe is located directly above the combustion chamber 20, and the first notch may also be a straight-through groove.

[0105] See Figure 9 , Figure 19 and Figure 20 As shown, in some embodiments, the second switching member 40 forms an arc-shaped surface 421 at the second notch. The arc-shaped surface 421 is located between the first pipe segment 722 and the second pipe segment 723 to cover the open portion. The two opposite arc-shaped edges of the second notch are respectively attached to the end faces of the first pipe segment 722 and the second pipe segment 723 that are close to each other. The two opposite straight edges of the second notch are attached to the two side end faces 641 of the arc-shaped inner wall 64 of the base 60, so that the first pipe segment 722 and the second pipe segment 723 are connected to form a complete channel. When the second notch is aligned with the connecting portion 721, it ensures that the gas can smoothly enter the combustion chamber 20 and reduces the risk of gas leakage.

[0106] In some embodiments, the combustion device further includes an on / off switch and a controller. The on / off switch is disposed in the housing 190, and the controller is installed inside the housing 190. The on / off switch is connected to the control system. The drive mechanism 10, the gas supply device 150, the automatic ignition device, the cleaning device 70, and the screw feeder 170 are all connected to the control system. For example, the on / off switch can be a push-button or a touch button. The controller can include a microcontroller unit (MCU) or a programmable logic controller (PLC).

[0107] It should be noted that the structure and working principle of the on / off switch and controller are well known to those skilled in the art and are easy to implement, and will not be described in detail here.

[0108] In some embodiments, the combustion device further includes a power supply device (not shown) to provide electrical energy to electrical components such as the drive mechanism 10, the gas supply device 150, and the automatic ignition device. The power supply device is installed inside the housing 190, which is provided with a charging port. The power supply device can be, but is not limited to, a lithium battery.

[0109] In some embodiments, the operation of the combustion device is as follows: See Figure 9 As shown, in standby mode, the first switching element 30 is in the filtration position, the second switching element 40 is in the air intake position, and the filter assembly 50 is located below the combustion chamber 20, which contains material. When the on / off switch is turned on, the combustion device enters the working state, the automatic ignition device starts, igniting the material in the combustion chamber 20, and the air supply device 150 starts, introducing outside air into the combustion chamber 20, which facilitates complete combustion and improves combustion efficiency. After combustion is complete, the air supply device 150 is turned off. (See also...) Figure 12As shown, when ash discharge is required, the power output shaft rotates in the first direction, the first one-way bearing is in the transmission state, so that the first switching element 30 switches to the ash discharge position, the ash hopper 31 is located below the combustion chamber 20, the second one-way bearing is in the idling state, so that the second switching element 40 is kept in the air intake position. At this time, the air supply device 150 is closed, and the cleaning device 70 discharges the combustion residue in the combustion chamber 20 into the ash hopper 31.

[0110] After the ash removal operation is completed, the power output shaft rotates in the second direction, the first one-way bearing is in an idle state, keeping the first switching element 30 in the ash removal position, and the second one-way bearing is in the transmission state, causing the second switching element 40 to switch to the feeding position; then the power output shaft rotates in the first direction again, causing the first switching element 30 to switch to the filtration position, while the second switching element 40 remains in the feeding position. At this time, see... Figure 6 As shown, the filter assembly 50 is located below the combustion chamber 20. The screw feeder 170 is activated to feed the material into the combustion chamber 20 through the feed channel 41 for future use.

[0111] Then the power take-off shaft rotates again in the second direction, keeping the first switching element 30 in the filter position while the second switching element 40 switches to the intake position. At this point, see... Figure 9 As shown, the combustion device is in standby mode.

[0112] In some embodiments, the second one-way clutch mechanism 90 can be omitted, while the first one-way clutch mechanism 80 is retained. The first one-way clutch mechanism 80 can be a first one-way bearing. The first output shaft 11 is connected to the first switching member 30 via the first one-way clutch mechanism 80. The drive mechanism 10 is configured such that when the power output shaft rotates in the first direction, the first one-way clutch mechanism 80 is in an idle state, so that the first switching member 30 remains in the current position, and the second output shaft 12 drives the second switching member 40 to perform position switching; when the power output shaft rotates in the second direction, the first one-way clutch mechanism 80 is in a driving state, so that the first switching member 30 performs position switching, and the second switching member 40 rotates synchronously to perform position switching. Because the second one-way clutch mechanism 90 is omitted, the operational relationship between the first switching member 30 and the second switching member 40 is different from that in the previous embodiment, and therefore the corresponding position switching process is also different. The specific operation process is as follows: In standby mode, the combustion chamber 20 is filled with material. The first switching element 30 is in the filtration position, and the second switching element 40 is in the air intake position. When the on / off switch is turned on, the combustion device enters the working state, the automatic ignition device is activated, and the material in the combustion chamber 20 is ignited. The air supply device 150 is activated, and outside air is introduced into the combustion chamber 20, which is conducive to the complete combustion of the material and improves the combustion efficiency. After combustion is completed, the air supply device 150 is turned off.

[0113] When ash discharge is required, the power output shaft rotates in the first direction, and the first one-way bearing is in an idle state, so that the first switching element 30 is kept in the filtration position. At the same time, the second output shaft 12 drives the second switching element 40 to switch to the feeding position. Then, the power output shaft rotates in the second direction, and the first one-way bearing is in the transmission state, so that the first switching element 30 switches to the ash discharge position. The ash hopper 31 is located below the combustion chamber 20. At the same time, the second output shaft 12 drives the second switching element 40 to switch to the air intake position. At this time, the air supply device 150 is still in the closed state, and the cleaning device 70 is started to discharge the combustion residue in the combustion chamber 20 into the ash hopper 31.

[0114] Then the power output shaft rotates again in the second direction, causing the first switching element 30 to switch to the filtration station, and the second switching element 40 to switch to the feeding station. At this time, the filter assembly 50 is located below the combustion chamber 20, and the screw feeder 170 is activated to send the material into the combustion chamber 20 through the feeding channel 41 for the next use.

[0115] Then the power output shaft rotates again in the first direction, so that the first switching element 30 remains in the filtration position, while the second switching element 40 switches to the intake position. At this time, the combustion device is in standby mode.

[0116] It should be understood that in the embodiments of this disclosure, in the standby state, the combustion chamber is already filled with material, the first switching element 30 is in the filtration position, and the second switching element 40 is in the air intake position. Therefore, when the user wants to use the combustion device, there is no need to perform a feeding operation first. The combustion device can be put into combustion state by starting the automatic ignition device, or by starting the automatic ignition device and the air supply device, thus improving the user experience.

[0117] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
