Description

Technical Field

[0001] This invention belongs to the field of smoking products technology, and particularly relates to an elastic repulsion damping structure and a low-temperature smoking device. Background Technology

[0002] Compared to traditional cigarettes, heated tobacco products directly heat tobacco or nicotine products at a temperature between 220-250℃. After being baked, the smoke gradually evaporates, which can reduce the harmful smoke components produced by the combustion and thermal degradation of tobacco in traditional cigarettes.

[0003] Heated tobacco products come in various shapes and sizes, but most of them have a cigarette insert for inserting a low-temperature cigarette into the heating chamber and a cleaning port for cleaning the heating chamber. Correspondingly, a dust cover is provided at the cigarette insert to cover the cigarette insert, and a cleaning cover is provided at the cleaning port to cover the cleaning port.

[0004] Whether it's a dust cover or a cleaning cover, it must have the function of switching between open and closed states. This requires a mechanical structure to support the opening and closing function. The existing dust covers and cleaning covers have no damping or poor damping when pushed. Because they need to be pushed back and forth at a relatively high frequency during use, the resistance often increases after a period of use, making it difficult to open or close, resulting in a poor user experience for consumers. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide an elastic repulsive damping structure and a low-temperature smoking device.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] An elastic repulsive damping structure is disposed between a fixed component and a sliding component that slides relative to the fixed component. It includes a spring sheet disposed on the fixed component and an abutting part disposed on the sliding component. The spring sheet has a sliding convex surface, and the abutting part slides against the sliding convex surface. When the abutting part slides from one end of the sliding convex surface to the other end by the driving force of the sliding component, the spring sheet undergoes elastic deformation and recovers, thereby providing the sliding component with sliding resistance and sliding assistance in turn.

[0008] A low-temperature smoking device includes a smoking device body and a cover that can slide relative to the smoking device body between an open position and a closed position; when the cover is in the closed position, the opening on the smoking device body is covered by the cover, and when the cover is in the open position, the opening is open;

[0009] The cover and the body of the smoking device are provided with an elastic repulsive damping structure between the open position and the closed position. The elastic repulsive damping structure includes a spring sheet disposed on the body of the smoking device and an abutment part disposed on the cover. The spring sheet is provided with a sliding convex surface in the sliding direction of the cover. The abutment part slides against the sliding convex surface. When the abutment part slides from one end of the sliding convex surface to the other end by the driving of the slider, the spring sheet undergoes elastic deformation and recovers, thereby providing sliding resistance and sliding assistance to the cover.

[0010] Furthermore, the opening is a cigarette insert or a cleaning port connected to the flue of a smoking device.

[0011] Furthermore, the smoking device body adopts a straight-through flue, and the two opposite openings of the straight-through flue are respectively set to form a cigarette insertion port and a cleaning port.

[0012] Furthermore, the smoking device body is provided with a cigarette inlet and a cleaning port that communicates with the flue of the smoking device. Both the cigarette inlet and the cleaning port are provided with a cover to cover them and an elastic repulsive damping structure.

[0013] Furthermore, the portion of the contacting part that contacts the sliding convex surface is designed to be spherical.

[0014] Furthermore, the cross-section of the portion of the spring sheet with the sliding convex surface is V-shaped.

[0015] Furthermore, a guide structure is provided between the cover and the smoking device body to limit the cover from sliding close to the smoking device body. When the cover slides to the two end positions of the guide structure, it respectively covers and exposes the opening.

[0016] Furthermore, the guiding structure includes a guide rail and a guide groove. The guide rail is disposed on the body of the smoking device along the sliding direction of the cover, and the guide groove is disposed on the cover and nested on the guide rail.

[0017] Furthermore, two sets of the guide structures are symmetrically arranged along the sliding direction of the cover.

[0018] Furthermore, the smoking device body is provided with a sliding groove for the cover to slide, and a slider that matches and is inserted into the sliding groove is provided on the end face of the cover facing the smoking device body. The guide structure is disposed between the side wall of the slider and the side wall of the sliding groove.

[0019] Furthermore, the portion of the spring with the sliding convex surface is suspended at the bottom of the slide groove, and the abutting part is disposed in the groove in the middle of the slider.

[0020] Furthermore, the portion of the spring sheet located on one side of the sliding convex surface is a positioning part that is positioned and assembled with the body of the smoking device, while the portion located on the other side is bent to form a support part that abuts against the body of the smoking device.

[0021] The elastic repulsion damping structure of this invention is disposed between the fixed member and the sliding member. The elastic repulsion damping structure has a sliding convex surface that is high in the middle and low at both ends. When the sliding member drives the abutment part to slide between the two ends of the sliding convex surface, when the abutment part slides from the low end of the sliding convex surface toward the middle, the elastic piece undergoes elastic deformation, thereby giving the sliding member a sliding resistance that is opposite to the sliding direction and gradually increases. When the abutment part slides from one end (low end) of the sliding convex surface past the highest point in the middle to the other end (low end), the elastic piece elastically resets, giving the cover sliding assistance, making the cover sliding process easier and smoother, thus forming a damping sensation.

[0022] The low-temperature smoking device employing the aforementioned elastic repulsion damping structure opens the opening of the device when the contact part slides from one end of the sliding convex surface to the other, corresponding to the cover. Conversely, when the contact part slides in the opposite direction, it closes the opening of the device. The cover utilizes an elastic repulsion damping structure, ensuring physical contact between the cover and the spring sheet. During the process of opening or closing the opening by sliding the cover, the sheet metal spring sheet provides both frictional resistance and elastic deformation force to the cover. The special structure of the sliding convex surface of the sheet metal spring sheet generates excellent damping during the opening and closing process, greatly improving user comfort.

[0023] The opening of a low-temperature smoking device can be a cigarette inlet (with a corresponding dust cover) or a cleaning port (with a corresponding cleaning cover). Alternatively, an elastic repulsion damping structure can be installed on the cover corresponding to both the cigarette inlet and the cleaning port. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] See Figure 1 An elastic repulsive damping structure is disposed between a fixed member 1 and a sliding member 2 that slides relative to the fixed member 1, so that the sliding member 2 generates a damping sensation when sliding on the fixed member 1. It should be noted that in this embodiment, the fixed member 1 is not absolutely fixed, and can be the outer shell or body of a product, and the sliding member 2 slides relative to the fixed member 1.

[0037] The elastic repulsion damping structure of this embodiment includes a spring sheet 3 disposed on the fixed member 1 and an abutment part 4 disposed on the sliding member 2. The spring sheet 3 is provided with a sliding convex surface 5 that is high in the middle and low at both ends in the sliding direction of the sliding member 2. The abutment part 4 slides against the sliding convex surface 5. When the abutment part 4 slides from one end of the sliding convex surface 5 to the other end by the driving force of the sliding member 2, the spring sheet 3 undergoes elastic deformation and recovers, successively providing sliding resistance and sliding assistance to the sliding member 1.

[0038] In particular, when the sliding convex surface 5 is designed to gradually increase in height from both ends toward the middle, the contact part 4 can slide smoothly on the sliding convex surface 5.

[0039] The following will use the example of the slider 2 sliding from left to right on the fixed part 1 to explain the principle of the elastic repulsion damping structure damping product. Here, the two ends of the sliding convex surface are named the first low end and the second low end, and the middle part is named the high end because it is higher than the two ends:

[0040] The contact part 4 slides between the first low end and the second low end of the sliding convex surface 5, driven by the slider 2. When it starts to slide from the first low end and passes the high end, the spring piece 3 undergoes elastic deformation due to the pressure of the contact part 4, thereby giving the contact part 4 an elastic deformation force, and thus giving the slider 2 a sliding resistance. When the slider 2 slides on the fixed part 1, when the contact part 4 passes the high end and slides towards the second low end, the spring piece 3 gradually elastically resets, giving the slider 2 a boosting force, making the sliding process of the slider 2 easier and smoother, thus forming a damping feeling.

[0041] Whether the slider 2 slides from left to right or from right to left, the elastic repulsive damping structure can provide the slider 2 with the aforementioned sliding resistance, thereby providing a good sliding damping feel.

[0042] It is conceivable that in practical applications, the spring 3 can be made of stamped metal sheet, with the cross-section of the part with the sliding convex surface being V-shaped. That is to say, the sliding convex surface is composed of two intersecting slopes, and the contact point of the slopes needs to be designed to have a smooth transition in order to reduce the resistance of sliding and prevent the sliding part from getting stuck on the fixed part. In the above-mentioned structure, when the contact part 4 slides from both ends of the sliding convex surface 5 toward the middle, the elastic deformation force gradually increases, thus the sliding damping of the sliding part 2 is better.

[0043] See Figures 2-6 A low-temperature smoking appliance employing the aforementioned elastic repulsion damping structure includes a smoking appliance body and a cover that can slide relative to the smoking appliance body between an open position and a closed position. When the cover is in the closed position, the opening on the smoking appliance body is covered by the cover; when the cover is in the open position, the opening is open. The aforementioned elastic repulsion damping structure is provided between the cover and the smoking appliance body. Correspondingly, the fixing member 1 is the smoking appliance body, and the sliding member 2 is the cover. In this embodiment, the opening on the smoking appliance body is a cleaning port 6, and the cover corresponding to the sliding member 2 is a dust cover.

[0044] See Figure 2 This embodiment provides an example of a smoking device body, which includes a housing 7, a heating element 8 disposed within the housing 7, a battery 9, and a PCB board 10. The battery 9 and the PCB board 10 are electrically connected, and the PCB board 10 and the heating element 8 are electrically connected, that is, the battery 9 supplies power to the heating element 8 through the PCB board 10. A control button 11 is also provided on the housing 7. The heating element 8, the battery 9, the PCB board 10, and the control button 11 are electrically connected to form a control circuit. As for the specific control circuit structure, it is a conventional design in the field of circuit design and will not be described in detail here.

[0045] like Figure 2 and Figure 3As shown, the heating tube 8 forms a heating chamber inside. When in use, the low-temperature cigarette is inserted into the heating chamber. When the heating tube 8 is powered on, the temperature in the heating chamber rises, heating the low-temperature cigarette to the set temperature (usually 200-250 degrees Celsius, which can be preset as needed). The low-temperature cigarette produces smoke at this temperature.

[0046] In this embodiment, the heating chamber is a straight-through type, with a cleaning port 6 and a cigarette insertion port 12 connected to both ends of the heating chamber. During use, a low-temperature cigarette is inserted into the heating chamber through the cigarette insertion port 12. After smoking one cigarette, the low-temperature cigarette can be pulled out from the cigarette insertion port 12. The cleaning port 6 is also connected to the heating chamber. After the low-temperature smoking device has been used for a period of time, a brush can be inserted through the cleaning port 6 into the heating chamber to clean away tar, residue, and other residual substances. This prevents excessive accumulation of residual substances in the heating chamber during long-term use of the low-temperature smoking device, which could affect its normal operation.

[0047] like Figure 2 and Figure 3 As shown, a dust cover 13 is provided at the cigarette inlet 12, and a cleaning cover is provided at the cleaning port 6. Both the cleaning cover and the dust cover 13 can be moved to the open position and the closed position, thereby opening and closing the cleaning port 6 and the cigarette inlet 12 respectively.

[0048] See Figure 4 and Figure 5 When using the smoking device, push the dust cover 13 to the open position. At this time, the cigarette inlet 12 is exposed, and the cigarette can be inserted into the heating chamber from the cigarette inlet 12, while the dust cover is in the closed position. After use, the dust cover 13 can be pushed to cover the cigarette inlet 12 to prevent dust or other debris from falling into the heating chamber.

[0049] See Figures 2-5 To clean the low-temperature smoking device, push the dust cover to the open position, exposing the cleaning port 6. A brush can be inserted through the cleaning port and then rotated. To facilitate airflow, an air inlet 14 is provided on the cleaning cover. When using the low-temperature smoking device, this air inlet 14 is connected to the cleaning port 6, the heating chamber, and the cigarette insert 12, ensuring that airflow enters through the air inlet 14, passes through the cleaning port 6, and enters the heating chamber. Finally, the smoke produced by the cigarette in the heating chamber is carried into the user's mouth, forming a complete inhalation process. Furthermore, anti-slip protrusions 15 can be provided on the cleaning cover to prevent slippage when manually pushing it, making it more convenient to use.

[0050] In practical applications, a silicone part 16 can also be installed at the cleaning port 6, which is in close contact with the heating tube 8 to ensure the airtightness of the air passage connecting the cleaning port 6 and the heating chamber, and to prevent smoke and gas from entering other parts of the low-temperature smoking device.

[0051] See Figure 4 and Figure 5 In addition, in this embodiment, the battery can be a nickel-metal hydride battery, a lithium-ion battery or a hydrogen battery. In order to reduce the number of times the battery is replaced, the battery is designed as a rechargeable battery, and a battery charging port 17 is required accordingly. In this embodiment, the battery charging port 17 is located near the cleaning port 6, so that when the cleaning cover is in the open position, the battery charging port 17 can be covered.

[0052] Of course, it should be noted that the above is only a specific example of a smoking device body. For those skilled in the art, any smoking device body that includes an opening and a cover should fall within the scope of the smoking device body defined in this application.

[0053] The following will illustrate this application by taking the example of setting a cleaning cover and an elastic repulsion damping structure at the cleaning port.

[0054] See Figure 2 and Figure 3 The cleaning cover 2 is fixed to the outer shell 7 and can slide along the reserved space on the outer shell 7, allowing it to move between the open and closed positions of the cleaning port 6. During the movement of the cleaning cover 2, the contact part 4 on the cleaning cover 2 always maintains physical contact with the sheet metal spring 3 of the elastic repulsive damping structure. That is, during the sliding process, the cleaning cover 2 will be subject to frictional resistance and elastic deformation restoring force from the sheet metal spring 3, forming a certain damping sensation. In particular, when the contact part 4 slides to the two ends of the sliding convex surface on the sheet metal spring 3, the cleaning cover 2 slides to the open and closed positions respectively, so that the cleaning cover 2 has a damping sensation throughout the entire sliding process. In addition, when the cleaning cover 2 moves to the closed or open position, it needs to overcome the frictional resistance and elastic deformation restoring force of the sheet metal spring. The sheet metal spring 3 is equivalent to a locking force that locks the cleaning cover 2 in the closed or open position, which can prevent the cleaning cover 2 from automatically opening or closing under abnormal cleaning conditions.

[0055] The sheet metal spring 2 is fixed inside the outer shell 7 of the low-temperature smoking device. On one hand, it is in physical contact with the cleaning cover 2 and is pressed by the abutment part 4 on the cleaning cover 2. On the other hand, it is in contact with the support member 18 fixed in the outer shell 7 of the low-temperature smoking device and is stuck in the space formed by the support member 18, the outer shell 7 and the cleaning cover 2.

[0056] See Figures 7-9 In one embodiment, the low-temperature smoking appliance of this embodiment has a guide structure between the cleaning cover 2 and the outer shell 7, which limits the sliding of the cleaning cover to the outer shell 7. When the cleaning cover 2 slides to the two end positions of the guide structure, the cleaning port 6 is covered and exposed respectively.

[0057] See Figures 7-9In one embodiment, the low-temperature smoking appliance of this embodiment has a groove 20 on the bottom cover 19 of the outer shell 7 for the cleaning cover 2 to slide. The cleaning cover 2 has a slider 21 protruding from the end face of the bottom cover 20 and matching insertion into the groove 20. A guide structure is disposed between the groove 20 and the slider 21.

[0058] Specifically, the guide structure is arranged symmetrically in two sets along the sliding direction of the cleaning cover 2, including a guide rail (not shown in the figure) and a guide groove 22. The guide rail is set on the side wall of the slide groove 20 along the sliding direction of the cleaning cover, and the guide groove 22 is set on the side wall of the slider 21 and nested on the guide rail. The cleaning cover is guided by the guide rail and the guide groove 22 and is snapped into the bottom cover 20. With the above-mentioned guide structure, the cleaning cover is not easy to detach from the outer shell 7 and slides more smoothly on the bottom cover 20.

[0059] Preferably, the portion of the spring sheet 3 with the sliding convex surface 5 is suspended at the bottom of the slide groove 20, and the middle part of the slider 21 is recessed to form a groove 23. The contact part is disposed in the groove and aligned with the groove and abuts against the sliding convex surface. The part of the contact part that contacts the sheet metal spring sheet is designed as a spherical surface. During the sliding process of the cleaning cover, the spherical protrusion of the contact part directly bears the friction and elastic deformation force from the sheet metal spring sheet and transmits it to the entire cleaning cover, resulting in smooth sliding.

[0060] See Figure 10 and Figure 11 The spring piece 2 has a positioning part 201, a sliding part 202 and a supporting part 203 connected in sequence. The surface of the sliding part 202 facing the contact part is a sliding convex surface 5. The cross-sectional shape of the sliding part in the middle is V-shaped. The sliding convex surface 5 has a first slope 501 and a second slope 502. A transition vertex 503 is provided at the connection between the first slope 501 and the second slope 502. The slopes of the first slope 501 and the second slope 502 have different inclination directions. They both change slope as they move away from the transition vertex 503. This makes the movement on the sliding convex surface such that the first stage is from the first slope 501 to the transition vertex 503, the transition stage is when the transition vertex is reached, and the second stage is from the transition vertex 503 to the second slope 502.

[0061] See Figure 6 and Figure 10Specifically, the positioning part 201 is provided with a 24, and around the positioning hole 24 are distributed guide positioning fixing ears 25 and positioning correction ears 26, which facilitates the snap-fit ​​positioning with the outer shell 7 during installation. The spring piece 2 is positioned and assembled with the outer shell 7 through a snap fastener inserted in the positioning hole 24. The part of the spring piece 2 located on the other side of the sliding convex surface 5 is a support part 203 that abuts against the body of the smoking device. The end of the support part 203 away from the sliding convex surface 5 is bent and fixed by the support member 18. The part of the support part 203 that contacts the support member 18 has a relatively flat surface, so that there is a surface contact (or line contact) between the sheet metal spring piece and the support member 18, so that the resistance is uniform when the cleaning cover 2 is pushed left and right.

[0062] Combination Figure 6 , Figure 10 and Figure 11 The spherical protrusion of the contact part 4 on the cleaning cover is in physical contact with the sheet metal spring 3. During the sliding process of the cleaning cover opening / closing the cleaning port 6, the spherical protrusion of the cleaning cover 6 slides between the first slope 501, the transition vertex 503 and the second slope 502 (always maintaining contact with the sheet metal spring). When it starts to slide from the first slope 501, passes the transition vertex and reaches the second slope 502, the corresponding cleaning cover opens the cleaning port 6 of the low-temperature smoking device; when it starts to slide from the second slope 502, passes the transition vertex 503 and reaches the first slope 501, the corresponding cleaning cover closes the cleaning port 6 of the low-temperature smoking device. Referring to the above paragraph, during the process of sliding to the transition vertex in the first stage and the process of sliding to the transition vertex in the second stage, the sliding resistance increases under the action of the sheet metal spring 2. When it passes the transition vertex 503, the sheet metal spring returns to its original position, the sliding resistance decreases, and the sliding process becomes easier and smoother, thus forming a damping sensation.

[0063] Applying the above process to the opening and closing of the cleaning cover, when opening or closing the cleaning cover, after initially pushing with force, the damping gradually increases. The user will subconsciously increase the pushing force appropriately. After a certain point, the resistance decreases. The pushing force accumulated in the first half makes pushing in the second half easier, resulting in a better user experience.

[0064] Finally, it should be noted that the above is merely an illustrative description of the case where the opening is a cleaning port and the cover is a cleaning cover. For those skilled in the art, the opening and cover in this application should not be limited to cleaning ports and cleaning covers, but can also be a cigarette inlet or other openings. Correspondingly, the cover can be a dust cover corresponding to the cigarette inlet or other covers. Furthermore, if the smoking device body has multiple openings, a cover with the above-described structure and an elastic repulsion damping structure can be provided for each opening. For example, the above-described elastic repulsion damping structure can be provided simultaneously at the cigarette inlet and dust cover, and at the cleaning port and cleaning cover.

[0065] The above embodiments are merely illustrative examples to clearly illustrate the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
