Description

Technical Field

[0001] The present application belongs to the field of novel tobacco, and specifically relates to a heating smoking device. Background Art

[0002] In recent years, heat-not-burn cigarette products have become increasingly popular. They are mainly a product that converts nicotine and other substances in tobacco into vapor through means such as atomization, which is then inhaled by users.

[0003] At present, the heating process of cigarette paper can be cleverly designed to produce specific visual effects when smoking. This innovation mainly relies on the temperature-sensitive properties of thermal ink. During the operation of the heated smoking device, the airflow temperature acts on the thermal ink on the cigarette paper, causing the ink to change color when it reaches a specific temperature, thereby showing a preset logo or text information on the cigarette paper.

[0004] However, although this thermal color development technology has shown significant advantages in improving user experience and product aesthetics, it also introduces a series of problems that cannot be ignored. The first is safety considerations. The use of thermal inks and thermal papers may bring potential health risks. These special materials may release unknown chemicals during the heating process. After these substances mix with tobacco smoke, they may cause unknown effects on the consumer's respiratory system, increasing the safety risks during the smoking process.

[0005] Secondly, using thermal paper or applying thermal ink on it as cigarette paper material will inevitably lead to a significant increase in the production cost of cigarettes. More importantly, when consumers use heated smoking devices to smoke ordinary cigarettes that do not use thermal technology, they will not be able to enjoy the visual experience of the unique logo dynamically formed on the surface of the cigarette paper during the heating process. This lack undoubtedly weakens the differentiated charm of the product and the fun of personalized interaction. Summary of the invention

[0006] In view of this, the purpose of this application is to provide a heating smoking device to solve the above problems.

[0007] In order to solve the above technical problems, this application adopts the following technical solutions:

[0013] Further, when the pressure sensing element senses that the pressure value exerted on the second heating element is within a preset pressure value range and / or senses that the pressure exerted on the second heating element lasts for a preset time threshold, the control system controls the driving element to drive the second heating element to be movably set in the first position and the second position along the axial direction of the heating chamber.

[0014] Furthermore, a slide groove is provided on the surface of the heating chamber along its own axial direction, and a driving member and a connecting member are arranged in the slide groove. The driving member drives the second heating member along the slide groove to movably heat the outer surface of the cigarette to form an identification pattern.

[0015] Furthermore, the identification system also includes a temperature sensing element, which is arranged close to the second heating element and connected to the control system. The temperature sensing element is used to monitor the heating temperature of the second heating element and feed back the heating temperature to the control system.

[0016] Furthermore, the pressure sensing element is a strain gauge pressure sensor or a piezoresistive pressure sensor.

[0017] Furthermore, the first heating element is an internal heating element, which is inserted into the interior of the cigarette during heating.

[0018] Among them, the cigarette can be called an aerosol-generating product, a smoking product, and the tobacco portion of the cigarette can be called an aerosol-forming substrate, which generates an aerosol that can be directly inhaled into the user's lungs through the user's mouth by heating.

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] Please refer to Figure 1 and Figure 2 The present application provides a heating smoking device 1 , which may include: a heating system, a power supply system 3 , a control system 2 and an identification system 6 .

[0044] The heating system includes a heating chamber 4 and a first heating element 5. The first heating element 5 is used to heat the cigarettes contained in the heating chamber 4 to generate smoke under the action of the power supply system 3.

[0045] The power supply system 3 may include a power supply device, and the power supply device may be a power adapter.

[0046] The heating smoking device 1 can be operated by the electric energy provided by the power supply device, or the electric energy provided by the power supply device can be charged into the battery. When the heating smoking device 1 is operated by the electric energy provided by the power supply device, the heating smoking device 1 can be driven by the electric energy to operate various built-in electronic units, and the electronic units can include various power-consuming electronic components, which will not be described in detail here.

[0047] Optionally, the first heating element 5 may be an internal heating element, which may be a heating needle or a heating sheet, and the internal heating element is located in the heating chamber 4 and maintains a certain distance from the cigarette in the initial state. When heating, the internal heating element is inserted into the interior of the cigarette to heat the tobacco segment in the cigarette to generate smoke.

[0048] The first heating element 5 may also be an external heating element, which is located outside the heating chamber 4, and the heat can be directly transferred to the surface of the cigarette.

[0049] The first heating element 5 can also be a combination of an internal heating element and an external heating element, and the cigarette is heated by two heat sources, the internal heating element and the external heating element.

[0050] The control system 2 is connected to the power supply system 3 and the first heating element 5 , and is used to control the heating temperature of the first heating element 5 .

[0051] Optionally, the control system 2 may be a microprocessor or a single chip microcomputer, and the control system 2 is responsible for receiving signals generated by other relevant sensor elements, executing control algorithms, and outputting control signals to corresponding electronic elements.

[0052] The marking system 6 can be used to form a marking pattern on the outer surface of the cigarette according to the control signal provided by the control system 2. The marking system 6 is operated by the power supply system 3 providing power and the control system 2 controlling the power supply system 3.

[0053] The marking system 6 includes a marking element, which has a heating function. After being powered on, the marking element can quickly rise to a high temperature, and after contacting the cigarette paper on the outer surface of the cigarette, an irreversible dark mark can be quickly formed on the cigarette paper through a thermal reaction.

[0054] Specifically, the identification element includes a connecting member 6-2 and a second heating member 6-3. The second heating member 6-3 is connected to the power supply system 3 and the control system 2. The connecting member 6-2 is arranged in the heating chamber 4. The second heating member 6-3 is connected to the connecting member 6-2. The second heating member 6-3 is used to heat at a first position on the outer surface of the cigarette to form an identification pattern.

[0055] The first position may be that the cigarette is inserted into the first heating element 5, and the second heating element 6-3 and the cigarette are on the same horizontal plane, forming an aligned relative position.

[0056] The maximum heating temperature of the second heating element 6 - 3 is not less than 300° C. Preferably, the operating temperature range of the second heating element 6 - 3 is 300-400° C.

[0057] The second heating element 6-3 is kept at the operating temperature for no less than 5 seconds. Preferably, the second heating element 6-3 is kept at the operating temperature for 5 to 10 seconds.

[0058] It can be understood that the second heating element 6 - 3 is suitable for carbonizing the cigarette paper part of the cigarette in this temperature range and operating period, which can produce a dark color change but will not produce obvious odor to affect the user's smoking taste.

[0059] The connecting member 6 - 2 is a support rod, and the second heating member 6 - 3 is a heating wire. The support rods include at least two of them. The support rods are used to support the heating wire, provide electrical conduction and power for the heating wire, and transmit signals to the control system 2 .

[0060] The heating wire is preferably a resistance heating wire. After the resistance heating wire is energized, the resistance heating wire is in a heating state and contacts with the cigarette paper of the cigarette to form a dark graphic mark.

[0061] The diameter of the heating wire does not exceed 1 mm. Preferably, the diameter of the heating wire is 0.3-0.7 mm.

[0062] The material of the heating wire can be selected from any one of the following materials: platinum, tungsten, nickel, copper and alloys thereof.

[0063] The shape of the heating wire can be set according to the required logo graphics or text information, and the maximum width of the heating wire does not exceed 7 mm, preferably 2 to 4 mm. The overall shape of the heating wire is an arc to fit the surface of the cigarette.

[0064] The second heating element can also be a device such as plasma, laser, etc. that can be used to heat the lettering.

[0065] The identification system 6 further includes a pressure sensing element, which is arranged close to the second heating element 6-3. The pressure sensing element is used to sense the pressure received by the second heating element 6-3 and convert the pressure into an electrical signal for transmission to the control system 2.

[0066] Specifically, a pressure sensing element is integrated on the second heating element 6-3, and the pressure sensing element establishes a communication connection with the control system 2. The pressure sensing element can be a strain type pressure sensor or a piezoresistive pressure sensor to ensure accurate pressure detection. At the same time, at least one pressure sensor is also equipped on the support rod, including metal strain gauge type, semiconductor strain gauge type or piezoresistive type, to further enhance the pressure sensing ability of the system.

[0067] It can be understood that when the pressure sensing element detects the pressure received by the second heating element 6-3, it indicates that the second heating element 6-3 is in contact with the cigarette.

[0068] When the pressure value sensed by the pressure sensing element on the second heating element 6-3 is within the preset pressure value range, the second heating element 6-3 starts to work to ensure that the cigarette can correctly contact the second heating element 6-3, and at the same time avoid excessive pressure exerted on the second heating element 6-3 by cigarettes with non-compliant sizes, thereby affecting the identification effect of the identification system 6 on the cigarette surface.

[0069] Exemplarily, the pressure value range can be 4N < F < 10N, 10N < F < 15N or 15N < F < 20N, etc.

[0070] When the duration for which the pressure sensing element senses the pressure received by the second heating element 6-3 reaches the preset duration threshold, the second heating element 6-3 starts to work to avoid mis-starting of the second heating element 6-3 and lack of a heating object, thereby affecting the service life of the identification system 6.

[0071] Exemplarily, the duration threshold is 4 seconds, 5 seconds, 6 seconds, 7 seconds or more, and the present application is not limited thereto.

[0072] The identification system 6 further includes a temperature sensing element, which is arranged close to the second heating element 6-3. The temperature sensing element is connected to the control system 2. The temperature sensing element is used to monitor the heating temperature of the second heating element 6-3 and feedback the heating temperature to the control system 2.

[0073] Specifically, the temperature sensing element can be a thermocouple. The power supply system 3 and the control system 2 can separately monitor the heating temperature of the second heating element 6-3 according to the thermocouple, generate corresponding temperature signals, and the control system 2 adjusts the heating power and start-stop state of the second heating element 6-3 according to the temperature signals, so that the operating temperature of the second heating element 6-3 is maintained within the set temperature range.

[0074] The temperature sensing element and the pressure sensing element can work together to generate accurate temperature signals and pressure signals respectively. The control system 2 flexibly adjusts the heating power and start / stop state of the second heating element 6-3 according to these signals to ensure stable operation and high efficiency of the system.

[0075] In an implementable manner of the present application, the temperature sensing element and the pressure sensing element are integrated into one body to form a sensing system 6 - 4 , and the sensing system 6 - 4 is disposed on the connecting member 6 - 2 .

[0076] The identification system 6 also includes a driving member 6-1. A slide groove is provided on the surface of the heating chamber 4 along its own axial direction. The driving member 6-1 and the connecting member 6-2 are arranged in the slide groove. The driving member 6-1 is connected to the connecting member 6-2 and the control system 2 respectively. The driving member 6-1 is used to drive the connecting member 6-2 to drive the second heating member 6-3 to be movably arranged at the first position and the second position in the axial direction of the heating chamber 4 along the slide groove to form an identification pattern.

[0077] It should be noted that the axial direction refers to the direction in which the cigarette is inserted into the heating chamber inside the heating device 1 , and can also be understood as the direction in which the cigarette extends from the proximal end to the distal end inside the heating device 1 .

[0078] The surface of the heating chamber 4 may also be designed without a slide groove, and the connecting member 6-2 and the second heating member 6-3 may be directly installed on the outer surface of the heating chamber 4. In this case, the driving member 6-1 is responsible for driving the second heating member 6-3 to flexibly move between the predetermined first position and the second position on the heating chamber 4.

[0079] Exemplarily, the first position may be the distal end of the heating device 1 , and the second position may be the proximal end of the heating device 1 .

[0080] During the movement of the second heating element 6 - 3 between the first position and the second position, the second heating element 6 - 3 starts heating to form a logo pattern on the surface of the cigarette paper of the cigarette.

[0081] It can be understood that, compared with the method in which the driving component is not integrated in the marking system 6, the introduction of the driving component 6-1 can make the process of the second heating component 6-3 forming the marking pattern on the surface of the cigarette paper more flexible and changeable. At the same time, this improvement also effectively alleviates the problem of poor marking pattern formation effect caused by the second heating component 6-3 heating time being too long, thereby improving the overall marking quality and effect.

[0082] The driving member 6-1 can also cooperate with the sensor system 6-4, and the specific process is as follows:

[0083] When the sensing system 6 - 4 is not in the preset pressure range, the driving element 6 - 1 stops running, and when the identification pattern is formed, the driving element 6 - 1 drives the second heating element 6 - 3 to return to the initial position.

[0084] When the sensing system 6 - 4 detects that the temperature of the second heating element 6 - 3 is too high, the driving element 6 - 1 will start and cause the second heating element 6 - 3 to move to the corresponding position.

[0085] When the driving member 6-1 drives the second heating member 6-3 to move between the first position and the second position, if the pressure sensing module does not sense pressure, it indicates that there is no cigarette in the heating chamber 4, and the driving member 6-1 drives the second heating member 6-3 back to the initial position.

[0086] In a first embodiment of the present application, the identification system 6 of the heating smoking device 1 is composed of a connecting member 6 - 2 , a second heating member 6 - 3 and a sensor system 6 - 4 .

[0087] Specifically, the sensor system 6 - 4 is capable of generating a sensor signal, which is then received by the control system 2 and used to regulate the start and stop status of the second heating element 6 - 3 .

[0088] In a second embodiment of the present application, the identification system 6 of the heating smoking device 1 is composed of a connecting member 6 - 2 , a second heating member 6 - 3 and a driving member 6 - 1 .

[0089] Specifically, the driving element 6-1 can drive the second heating element 6-3 to move more flexibly and precisely on the surface of the cigarette, which not only enhances the hot stamping effect of the second heating element 6-3 on the surface of the cigarette paper, but also significantly improves the overall quality and visual effect of the logo pattern.

[0090] In a third embodiment of the present application, the identification system 6 of the heating smoking device 1 is composed of a connecting member 6-2, a second heating member 6-3, a sensor system 6-4 and a driving member 6-1.

[0091] Specifically, with the help of the sensor signal generated by the sensor system 6-4, the system can intelligently control the moving trajectory of the driving member 6-1 and the working state of the second heating member 6-3, so that the entire identification system 6 not only demonstrates a more advanced level of intelligence in the process of generating the identification pattern, but also effectively ensures the accuracy and high quality of the identification pattern forming effect.

[0092] It can be understood that by arranging the marking system 6 inside the heated smoking device 1, a dark graphic mark can be generated on the surface of the cigarette paper of the cigarette during smoking. The method for forming the graphic mark of the scheme of the present invention is to use the high-temperature resistance wire of the marking system 6 to locally heat the cigarette paper, so that the cigarette paper undergoes a certain degree of thermal cracking, thereby the carbonization color becomes darker.

[0093] It can be seen that the scheme of the present invention can form graphic logos on the surface of heated cigarettes of any brand and any category, and is widely applicable. In addition, the scheme of the present invention does not require the use of additional consumables or changes in the cigarette production process, and has low technical costs and no safety risks.

[0094] In addition, the heating tobacco device of the present application can form a unique identification pattern on the surface of the cigarette paper of the cigarette. This design is not only decorative, but also can effectively prevent the cigarette from being used without authorization or accidentally inhaled by others by determining whether the identification pattern is formed.
