Description

Technical Field

[0001] The present invention belongs to the technical field of smoking articles, and particularly relates to a low-temperature smoking appliance. Background Art

[0002] When sucking a low-temperature cigarette, the cigarette needs to be inserted into the heating cavity of the appliance. And to ensure the reliability of heating, the cigarette generally cannot move during the sucking process. Ordinary low-temperature smoking appliances on the market rely on the friction force between the heating cavity and the cigarette to fix the cigarette, and this method has great drawbacks. When the cigarette and the heating cavity are in an interference fit, it will be difficult to insert the cigarette into the heating cavity. If the cigarette and the heating cavity are in a clearance fit, consumers are very likely to accidentally pull out the cigarette from the heating cavity during the process of smoking the cigarette, which affects the consumers' experience. And this problem also leads to poor compatibility of the appliance with cigarettes of different sizes. Summary of the Invention

[0003] The main purpose of the present invention is to provide a low-temperature smoking appliance, aiming to effectively avoid the cigarette being taken out of the heating cavity during the sucking process.

[0004] To achieve the above purpose, the present application adopts the following technical solutions:

[0005] A low-temperature smoking appliance, including a smoking appliance housing, a heating cavity for accommodating a cigarette is formed in the smoking appliance housing, an elastic ring is sleeved outside the heating cavity, at least one convex block is arranged on the inner side of the elastic ring, and a through hole corresponding to the position of the convex block is arranged on the side of the heating cavity;

[0006] A linear driving member fixedly connected to the elastic ring is further arranged in the smoking appliance housing. When the linear driving member pulls the elastic ring to force it to elastically deform, the convex block inserts into the heating cavity from the corresponding through hole.

[0007] Specifically, the number of the convex blocks is two, and the two convex blocks are symmetrically arranged on both sides of the linear driving member.

[0008] Specifically, the pulling direction of the linear driving member is perpendicular to the central axis of the elastic ring.

[0009] Specifically, one end of the elastic ring away from the linear driving member is fixedly connected to the heating cavity.

[0010] Specifically, the linear driving member is a linear motor.

[0011] Specifically, the heating cavity has opposite first and second ends; wherein, the first end is used for inserting the cigarette, and the second end is a closed end.

[0012] Specifically, an air intake groove is formed on the inner bottom surface of the second end;

[0013] The airflow enters the air inlet groove from the first end through the side gap between the cigarette and the heating chamber, and finally flows out of the cigarette.

[0014] Specifically, a heating element is provided in the middle of the heating chamber.

[0015] Specifically, a battery and a circuit board are further provided in the smoking device housing, and the battery, the heating element and the linear driving element are all electrically connected to the circuit board.

[0016] Specifically, the elastic ring is arranged close to the first end.

[0017] Specifically, the end surface of the protrusion facing the heating chamber is an arc-shaped surface, and the arc-shaped surface is adapted to the cigarette.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] A start command is given to the linear drive component, which pulls the elastic ring to force it to deform elastically, so that the protrusion is inserted into the heating chamber from the corresponding through hole, thereby clamping the cigarette in the heating chamber. Then the heating chamber starts to heat the cigarette and the smoking process begins. After the cigarette is smoked, the linear drive component moves in the opposite direction, and the protrusion withdraws from the heating chamber under the restoring force of the elastic ring, thereby loosening the cigarette, at which time the cigarette can be taken out.

[0020] The entire smoking device has the function of automatically clamping the cigarette, which can effectively prevent the cigarette from being pulled out of the heating chamber during the smoking process. In addition, even if there is an error in the diameter of the cigarette, the smoking device can also adapt to it, giving consumers an unchanged experience. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] See Figures 1 - 4 , a low-temperature smoking device, including a smoking device housing 1, a heating chamber 3 for accommodating a cigarette 2 is formed in the smoking device housing 1. The cigarette 2 can be inserted into the heating chamber 3 and can be heated by a heating element 4 in the heating chamber 3 to generate smoke for the user to inhale. After the cigarette 2 is smoked, it can be removed from the heating chamber 3. A battery 5 for supplying power to the heating element 4, a circuit board 6 for controlling the operation of the heating element 4, and a control button 7 are further provided in the smoking device housing 1. The circuit board 6 is electrically connected to the control button 7, the battery 5, and the heating element 4 to form a heating element heating control circuit. As for the specific structure of the heating element heating control circuit, it is a conventional design in the field of electronic control and will not be elaborated here. By pressing the control button 7, the heating element heating control circuit can be controlled to supply power to and cut off power from the heating element 4.

[0031] It should be explained here that the heating method of the smoking device can adopt central heating or surrounding heating. In this embodiment, the central heating method is adopted. The heating element 4 is arranged at the center of the heating chamber 3 and is installed in the smoking device housing 1 through a fixing seat 8. The heating element 4 is arranged in a sheet shape or a rod shape, so that it can be conveniently inserted into the cigarette 2. Of course, the surrounding heating method can also be adopted. Correspondingly, the heating element 4 is arranged on the inner periphery or the outer periphery of the heating chamber 3.

[0032] See Figures 4 - 6, an elastic ring 9 is sleeved outside the heating chamber 3 of the low-temperature smoking device. Among them, the elastic ring 9 has a certain elasticity. When it is subjected to pressure, it can produce a certain deformation and its shape can automatically recover when the pressure disappears. The elastic ring 9 can withstand high temperatures of 100 - 200 °C and its chemical and physical properties will not change significantly. Its material can be PEEK (polyetheretherketone). At least one convex block 10 is provided on the inner side of the elastic ring 9 (the side close to the heating chamber 3), and a through hole 13 corresponding to the position of the convex block 10 is provided on the side of the heating chamber 3. A linear drive member 11 fixedly connected to the elastic ring 9 is further provided in the smoking device housing 1, and the linear drive member 11 is controlled by the circuit board 6. The circuit board 6 gives a start instruction to the linear drive member 11, and the linear drive member 11 pulls the elastic ring 9, which can force the elastic ring 9 to undergo elastic deformation, so that the convex block 10 is inserted into the heating chamber 3 from the corresponding through hole 13, and the cigarette 2 in the heating chamber 3 is clamped.

[0033] In the embodiment of the present application, when a start instruction is given to the linear drive member 11, the linear drive member 11 pulls the elastic ring 9, which can force the elastic ring 9 to undergo elastic deformation, so that the convex block 10 is inserted into the heating chamber 3 from the corresponding through hole 13, thereby clamping the cigarette 2 in the heating chamber 3. Then the heating chamber 3 starts to heat the cigarette 2, and the suction process begins. After the cigarette 2 is smoked, the linear drive member 11 moves in the reverse direction, and the convex block 10 exits from the heating chamber 3 under the restoring force of the elastic ring 9, thereby loosening the cigarette 2. At this time, the cigarette 2 can be taken out. The entire smoking device has the function of automatically clamping the cigarette 2, which can effectively prevent the cigarette 2 from being taken out of the heating chamber 3 during the suction process. Moreover, the automatic clamping of the cigarette can be realized only by the elastic ring 9 and the linear drive member 11, with a simple structure and convenient operation. In addition, even if there is an error in the diameter of the cigarette 2, the smoking device can still adapt, giving consumers a consistent experience.

[0034] Specifically, to improve the reliability of the clamping of the cigarette 2, the number of the convex blocks 10 is two, and the two convex blocks 10 are symmetrically arranged on both sides of the linear drive member 11. The pulling direction of the linear drive member 11 is perpendicular to the central axis of the elastic ring 9.

[0035] In some possible implementation schemes, one end of the elastic ring 9 far from the linear drive member 11 is fixedly connected to the heating chamber 3, and the linear drive member 11 is a linear motor, and the shaft of the linear motor is connected to the elastic ring 9. Of course, the linear drive member 11 can also adopt structures such as an oil cylinder, a cylinder or a screw lifting mechanism.

[0036] It can be understood that the heating chamber 3 has opposite first and second ends; among them, the first end is used for inserting the cigarette 2, the second end is a closed end, and the heating element 4 is fixedly installed on the closed end. Tar and other dirt generated by smoking the cigarette 2 will not enter other parts of the smoking device, and the smoking device is convenient to clean.

[0037] In some possible embodiments, an intake groove 12 is provided on the inner bottom surface at the second end. When the cigarette rod 2 is inserted into the heating chamber 3 and abuts against the inner bottom surface at the second end of the heating chamber 3, the cigarette rod 2 is inserted in place. At this time, under the action of the suction negative pressure, the external fresh air flow enters the intake groove 12 from the first end of the heating chamber 3 through the side gap between the cigarette rod 2 and the side wall of the heating chamber 3, enters the cigarette rod 2 from the bottom end of the cigarette rod 2, and finally enters the user's mouth. The smoking device of this embodiment adopts the side intake method, which can not only preheat the fresh air flow and save energy consumption, but also cool down the smoking device housing 1.

[0038] In addition, it should be explained that the cigarette rod 2 in the embodiment of the present application includes a tobacco section and a filter section. When the cigarette rod 2 is inserted into the heating chamber 3, at least part of the filter section protrudes out of the smoking device, so as to facilitate the user to hold the filter for suction. Of course, a cooling section can also be added between the tobacco section and the filter section. After the air flow passes through the cooling section, the temperature drops, and the temperature of the air flow is effectively reduced, which can avoid the hot smoke and improve the user's suction experience. In addition, when the elastic ring 9 is arranged near the first end, the reliability of clamping the cigarette rod 2 can be further improved.

[0039] It can be understood that when the end face of the convex block 10 facing the through hole 13 is designed as an arc surface adapted to the cigarette rod 2, the cigarette rod 2 can be clamped more firmly and is not easily clamped and broken.

[0040] Specifically, the smoking device housing 1 includes an upper cover 101, a middle housing 102 and a lower cover 103. The upper cover 101, the middle housing 102 and the lower cover 103 jointly enclose a cavity for accommodating components such as the battery 5 and the circuit board 6.

[0041] See Figures 1 - 6 , the working process of the low-temperature smoking device in the embodiment of the present application is as follows:

[0042] Put the cigarette rod 2 into the heating chamber 3. At this time, the shaft of the linear motor is in the extended state, and the convex block 10 on the elastic ring 9 is located in the through hole 13 of the heating chamber 3 and the convex block 10 does not contact the cigarette rod 2.

[0043] Give the smoking device a start command, the shaft of the linear motor retracts, and the elastic ring 9 is pulled by the linear motor so that the convex block 10 on the elastic ring 9 moves towards the cigarette rod 2 and clamps the cigarette rod 2. Then the heating element 4 starts to heat the cigarette rod 2, and the suction process begins.

[0044] After the cigarette rod 2 is smoked, the shaft of the linear motor extends, the elastic ring 9 releases the cigarette rod 2, and at this time, the cigarette rod 2 can be taken out.

[0045] The above embodiments are merely examples clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the embodiments here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
