Description

Technical Field

[0001] The invention belongs to the technical field of smoking articles, and in particular relates to a low-temperature smoking article with a cigarette clamping function. Background Art

[0002] When smoking low-temperature cigarettes, the cigarette needs to be inserted into the heating chamber of the device, and in order to ensure the reliability of heating, the cigarette generally cannot move during the smoking process. Ordinary low-temperature smoking devices on the market rely on the friction between the heating chamber and the cigarette to fix the cigarette, which has major disadvantages. When the cigarette and the heating chamber are interference fit, it will make it more difficult to insert the cigarette into the heating chamber. If the cigarette and the heating chamber are clearance fit, it is very easy for consumers to accidentally pull the cigarette out of the heating chamber during the smoking process, affecting the consumer experience. This problem also leads to poor compatibility of the device with cigarettes of different sizes. Summary of the invention

[0003] The main purpose of the present invention is to provide a low-temperature smoking device with a cigarette clamping function, so as to effectively prevent the cigarette from being taken out of the heating chamber during the smoking process.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] A low-temperature smoking device with a cigarette clamping function, comprising a smoking device shell, wherein a heating chamber for accommodating cigarettes is formed in the smoking device shell, wherein two clamping arms that can be opened and closed relative to each other are provided in the smoking device shell, wherein each of the clamping arms is provided with a clamping block, wherein the two clamping blocks are symmetrically arranged on both sides of the heating chamber, and wherein two through holes corresponding to the two clamping blocks are provided on both sides of the heating chamber;

[0006] The smoking device housing is also provided with a driving member for driving the two clamp arms to open and close. When the driving member drives the two clamp arms to close relative to each other, the clamp block is inserted into the heating cavity from the corresponding through hole.

[0007] Specifically, the rotating ends of the two clamp arms are rotatably connected to the smoking device housing through their respective corresponding rotating shafts after being brought close to each other, and the rotating ends of the two clamp arms are driven by a pair of meshing shifting teeth, and the driving member is a linear driving member hinged to the rotating end of one of the clamp arms;

[0008] Wherein, the rotating end refers to an end of the clamping arm away from the clamping block.

[0009] Specifically, the end surface of the clamping block facing the through hole is an arc-shaped surface adapted to the cigarette, so as to facilitate clamping the cigarette and prevent the cigarette from being damaged when clamped.

[0010] Specifically, the linear drive component is a linear motor.

[0011] Specifically, the heating chamber has a first end and a second end opposite to each other; wherein the first end is used to insert the cigarette, and the second end is a closed end, so that pollutants such as tar will not enter other parts of the smoking device, and the smoking device is easy to clean.

[0012] Specifically, an air intake groove is formed on the inner bottom surface of the second end. The airflow enters the air intake groove from the first end through the side gap between the cigarette and the heating chamber, and finally flows out of the cigarette. By adopting the side air intake method, the fresh airflow can be preheated to save energy consumption, and the smoking device shell can be cooled at the same time.

[0013] Specifically, a heating element is provided in the middle of the heating chamber.

[0014] Specifically, a battery and a circuit board are also provided in the smoking device housing, and the battery, the heating element and the driving element are all electrically connected to the circuit board.

[0015] Specifically, a control button electrically connected to the circuit board is further provided on the side of the smoking device housing.

[0016] Specifically, the through hole is arranged close to the first end.

[0017] Specifically, the smoking device shell includes an upper cover, a middle shell and a lower cover.

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

[0019] A start command is given to the driving part, which drives the two clamping arms to close, so that the clamping blocks on the clamping arms are inserted into the heating chamber from the corresponding through holes, thereby clamping the cigarette in the heating chamber. The heating chamber then starts to heat the cigarette and the smoking process begins. After the cigarette is smoked, the driving part drives the two clamping arms to reset, and the clamping blocks release the cigarette, at which point the cigarette can be taken out. The smoking device has the function of automatically clamping the cigarette, which can effectively prevent the cigarette from being taken 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 DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 3, a low-temperature smoking device with a cigarette clamping function, comprises 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, and the cigarette 2 can be removed from the heating chamber 3 after the inhalation is completed, and a battery 5 for supplying power to the heating element 4, a circuit board 6 and a control button 7 for controlling the operation of the heating element 4 are also 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, forming a heating element heating control circuit, as for the specific structure of the heating element heating control circuit, they are all conventional designs in the field of electrical control, and will not be described here. By pressing the control button 7, the heating element heating control circuit can be controlled to supply power to the heating element 4 or cut off power.

[0032] It should be explained here that the heating method of the smoking device can be central heating or surrounding heating. The present embodiment adopts the central heating method, and the heating element 4 is arranged at the center of the heating chamber 3. The heating element 4 is arranged in a sheet or rod shape, so that it can be easily inserted into the cigarette 2. Of course, the surrounding heating method can also be adopted, and accordingly, the heating element 4 is arranged inside or outside the heating chamber 3.

[0033] See also Figure 4-Figure 6 Specifically, a clamping assembly 8 is further provided in the smoking device housing 1, and the clamping assembly 8 includes two clamping arms that can be relatively opened and closed. For the convenience of explanation, the two clamping arms are respectively named as a first clamping arm 801 and a second clamping arm 802. The first clamping arm 801 is provided with a first clamping block 803, and the second clamping arm 802 is provided with a second clamping block 804. The first clamping block 803 and the second clamping block 804 are symmetrically arranged on both sides of the heating chamber 3. The two sides of the heating chamber 3 are provided with a first through hole 9 and a second through hole 10 respectively corresponding to the two clamping blocks. The smoking device housing 1 is also provided with a driving member 805 for driving the two clamping arms to open and close. When the driving member 805 drives the two clamping arms to close relatively, the first clamping block 803 is inserted into the heating chamber 3 from the first through hole 9, and the second clamping block 804 is inserted into the heating chamber 3 from the second through hole 10, thereby clamping the cigarette 2 in the heating chamber 3, wherein the driving member 805 is controlled by the circuit board 6.

[0034] When it is necessary to smoke, the cigarette 2 is inserted into the heating chamber 3, and the circuit board 6 gives a start command to the driving member 805, driving the two clamping arms to close, so that the clamping blocks on the clamping arms are inserted into the heating chamber 3 from the corresponding through holes, thereby clamping the cigarette 2 in the heating chamber 3, and then the heating element 4 starts to heat the cigarette 2, and the smoking process begins. After the cigarette 2 is smoked, the driving member 805 drives the two clamping arms to reset, and the clamping blocks release the cigarette 2, and the cigarette 2 can be taken out at this time.

[0035] The smoking device in the embodiment of the present application has the function of automatically clamping the cigarette 2. Compared with the transition or interference fit between the cigarette 2 and the heating chamber 3, the cigarette 2 can be easily inserted into the heating chamber 3 without damaging the structure of the cigarette 2. In addition, even if there is an error in the diameter of the cigarette 2, the smoking device can also adapt to it, giving consumers an unchanged experience. Compared with the gap fit between the heating chamber 3 and the cigarette 2, the cigarette 2 will not be easily taken out when the consumer smokes.

[0036] See also Figure 4-Figure 6 It should be explained that, in some possible implementations, the rotating ends of the two clamp arms are brought close to each other and are rotatably connected to the smoking device housing 1 through their respective corresponding rotating shafts, and the rotating ends of the two clamp arms are driven by a pair of meshing shifting teeth, that is, the rotating end of the first clamp arm 801 is rotatably connected to the smoking device housing 1 through the first rotating shaft 11, and the rotating end of the second clamp arm 802 is rotatably connected to the smoking device housing 1 through the second rotating shaft 12, and the rotating ends of the first clamp arm 801 and the second clamp arm 802 are meshed and driven by a first shifting tooth 806 and a second shifting tooth 807, and the first shifting tooth 806 is arranged on the first clamp arm 801. On the rotating end, the second shifting tooth 807 is arranged on the rotating end of the second clamping arm 802, the center of the first shifting tooth 806 is located on the axis of the rotating end of the first clamping arm 801, and the center of the second shifting tooth 807 is located on the axis of the rotating end of the second clamping arm 802, and the driving member 805 is a linear driving member hinged to the rotating end of the first clamping arm 801; wherein, the rotating end refers to the end of the clamping arm away from the clamping block, and the linear driving member can adopt a linear motor, and of course, it can also adopt a structure such as an oil cylinder or an air cylinder. When the first clamping arm 801 rotates, it can drive the second clamping arm 802 to rotate synchronously through the shifting teeth, thereby controlling the opening and closing actions of the two clamping arms.

[0037] In the embodiment of the present application, the first clamping arm 801 and the second clamping arm 802 can be driven to open and close by a driving member 805 , and the clamping assembly 8 has a simple structure and is easy to operate.

[0038] It is understandable that when the end surfaces of the first clamping block 803 and the second clamping block 804 facing the corresponding through holes are designed to be arc-shaped surfaces adapted to the cigarette 2, the cigarette 2 can be clamped more securely and is not easily broken.

[0039] See also Figure 1 and Figure 2In some possible implementation schemes, the heating chamber 3 has a first end and a second end opposite to each other; wherein the first end is used to insert the cigarette 2, and the second end is a closed end, so that tar and other dirt generated by smoking the cigarette 2 will not enter other parts of the smoking device, and the smoking device is easy to clean. In particular, an air intake groove 13 is provided on the inner bottom surface of the second end, and when the cigarette 2 is inserted into the heating chamber 3 and abuts against the inner bottom surface of the second end of the heating chamber 3, the cigarette 2 is inserted into place. At this time, the external fresh airflow enters the air intake groove 13 from the first end of the heating chamber 3 through the side gap between the cigarette 2 and the side wall of the heating chamber 3 under the action of the suction negative pressure, and enters the cigarette 2 from the bottom end of the cigarette 2, and finally enters the user's mouth.

[0040] In the embodiment of the present application, the smoking device adopts a side air intake method, which can not only preheat the fresh airflow to save energy consumption, but also cool the smoking device shell 1.

[0041] In addition, it should be explained that the cigarette 2 in the embodiment of the present application includes a tobacco segment and a filter segment. When the cigarette 2 is inserted into the heating chamber 3, at least part of the filter segment leaks out of the smoking device, so that it is convenient for the user to hold the filter and smoke. Of course, a cooling segment can be added between the tobacco segment and the filter segment. The airflow cools down after passing through the cooling segment, which can prevent the smoke from burning the mouth and improve the user's smoking experience. Secondly, when the first through hole 9 and the second through hole 10 are arranged close to the first end, the reliability of clamping the cigarette 2 can be effectively improved.

[0042] Specifically, the smoking device shell 1 includes an upper cover 101, a middle shell 102 and a lower cover 103. The upper cover 101, the middle shell 102 and the lower cover 103 together form a cavity for accommodating components such as the clamping assembly 8, the battery 5 and the circuit board 6. The heating element 4 is installed inside the smoking device shell 1 through a fixing seat 14.

[0043] See also Figure 1-Figure 8 The working process of the present application is as follows:

[0044] The cigarette 2 is placed in the heating chamber 3 , at which time the driving member 805 is in an initial state, the clamping blocks on the first clamping arm 801 and the second clamping arm 802 are located in the corresponding through holes on the heating chamber 3 and the clamping blocks do not contact the cigarette 2 .

[0045] A start command is given to the smoking device, the driving shaft of the driving member 805 extends, the first clamping arm 801 rotates around the first rotating shaft 11 under the action of the driving member 805, and the first clamping block 803 on the first clamping arm 801 moves toward the cigarette 2 and contacts the cigarette 2. At the same time, the second clamping arm 802 rotates synchronously under the action of the shifting teeth, so that the second clamping block 804 on the second clamping arm 802 also contacts and clamps the cigarette 2, and then the heating element 4 starts to heat the cigarette 2, and the smoking process begins.

[0046] After the cigarette 2 is smoked, the driving shaft of the driving member 805 retracts, the first clamping arm 801 and the second clamping arm rotate in opposite directions and release the cigarette 2, and the cigarette 2 can be taken out at this time.

[0047] The above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods. For those skilled 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 list all the embodiments here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
