Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of heating cigarette, specifically relates to a heating cigarette apparatus and heating cigarette system. BACKGROUND

[0002] Traditional cigarettes, electronic cigarettes, heating cigarettes, oral tobacco, nicotine bags and other tobacco products all have nicotine delivery as the main consumption feature. New tobacco products such as electronic cigarettes, heating cigarettes and nicotine bags have less harm to consumers and can effectively deliver nicotine, so they are increasingly favored by consumers. In recent years, new tobacco products have shown a rapid growth trend in the international tobacco consumption market, and are the focus of major tobacco producers. Heating cigarettes have similar smoke characteristics to traditional burning cigarettes and have rapidly developed in the international market, and are expected to become the main tobacco consumer product. Innovations for heating cigarettes mainly focus on heating cigarette structure, heating methods and close integration with the apparatus to promote aerosol generation in tobacco products and efficient delivery to consumers.

[0003] Mature heating cigarette rods are generally cylindrical with a length of 42mm to 60mm and a circumference of 20mm to 24mm. They generally contain a smoking segment, a hollow segment, a cooling segment and a filter segment in the axial direction. The heating direction mainly includes circumferential heating, central heating, hot gas flow or aerosol heating. Circumferential heating refers to the placement of a heater around the smoking segment. Central heating generally involves the placement of a heating body inside the aerosol generating substrate or the insertion of a heating body during use to heat the aerosol generating substrate. The design of the airflow channel during the smoking process can also be divided into an airflow channel provided on the matching apparatus or a naturally formed airflow channel between the cigarette and the apparatus. After the airflow is introduced into the airflow channel and passes through the aerosol generating substrate, the aerosol formed by heating the aerosol generating substrate is carried out. Since the aerosol generating substrate is heated and airflow is introduced, the aerosol migrating from the downstream of the aerosol generating substrate has a high temperature, which needs to be cooled down by the cooling segment and / or the perforated filter segment before being delivered. For this type of product, due to the presence of the airflow channel on the apparatus, an airflow sensor (e.g., a microphone) can be placed in the airflow channel to record the consumer's puffing behavior characteristics, such as the number of puffs. The signal feedback from the airflow sensor can also control the atomizing heater, such as increasing the heater output power when sensing the puffing airflow and decreasing the heater output power when not sensing the puffing airflow.

[0004] Another type of heated cigarette (Chinese patents previously filed by the applicant in this case, such as 202010241676.5, 201911021676.8, and 201911021823, etc.) generally consists of a smoke-generating section, a hollow structure smoke-gas mixing section, and a filter section. The upstream end face of the aerosol-generating matrix is ​​sealed. The sealing method can be achieved by sealing the upstream end face of the aerosol-generating matrix with a matching smoking device, or by attaching a sealing rod or gas barrier membrane to the upstream end face of the aerosol-generating matrix. At the same time, an airflow channel is provided in the smoke-gas mixing section (for example, a channel of controllable size is provided in the hollow structure sidewall of the smoke-gas mixing section). During inhalation, the airflow bypasses the aerosol-generating matrix. Air enters the hollow structure of the smoke-mixing section through sidewall pores. The fluid flow in the mixing section creates negative pressure, drawing out the heated aerosol due to the pressure difference. This aerosol mixes with air entering from the outside through the sidewall pores and is then expelled through the filter. For such end-closed heated cigarettes, recording the consumer's inhalation behavior within the device becomes extremely difficult because the airflow channel is downstream of the aerosol-generating matrix in the heated cigarette, rather than within the device itself. Therefore, those skilled in the art generally do not incorporate airflow sensors into the device. How to record and acquire the consumer's inhalation behavior in this situation becomes a problem.

[0005] To address the above problems, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to design a smoking device for sealed heated cigarettes that can automatically detect the consumer's smoking behavior, based on the aforementioned existing technology.

[0007] The first aspect of this application provides a heated cigarette device, the heated cigarette device comprising: a cigarette holder, a sealing element, and a differential pressure sensor;

[0008] The bottom of the cigarette holder is sealed, and it is used to hold cigarettes.

[0009] The seal is configured to seal the gap between the cigarette holder and the cigarette;

[0010] One monitoring end of the differential pressure sensor is connected to the space formed by the seal, the cigarette, and the cigarette holder, while the other monitoring end is connected to the atmosphere.

[0011] The differential pressure sensor is configured to monitor the pressure difference between the air pressure and atmospheric pressure in the space formed by the seal, the cigarette, and the cigarette holder.

[0012] One end of the differential pressure sensor is used to monitor the pressure of the space formed by the sealing member, the cigarette, and the cigarette containing cylinder, and the other end is used to monitor the pressure of the external environment.

[0013] Preferably, the sealing member is a middle annular sealing member arranged between the bottom and the top of the cigarette containing cylinder, and / or a bottom annular sealing member arranged at the bottom of the cigarette containing cylinder.

[0014] When the sealing member is a middle annular sealing member, one monitoring end of the differential pressure sensor (also the connecting end with the cigarette containing cylinder) is arranged on the side wall or the bottom wall of the cigarette containing cylinder downstream of the middle annular sealing member.

[0015] When the sealing member includes a bottom annular sealing member, one monitoring end of the differential pressure sensor (also the connecting end with the cigarette containing cylinder) is arranged on the bottom wall of the cigarette containing cylinder and located in the hollow portion of the bottom annular sealing member.

[0016] Preferably, the sealing member is arranged in close contact with the side wall or the bottom wall of the cigarette containing cylinder.

[0017] Preferably, when one monitoring end of the differential pressure sensor (also the connecting end with the cigarette containing cylinder) is arranged on the side wall of the cigarette containing cylinder, a gap is provided between the upstream substrate surface of the cigarette and the bottom of the cigarette containing cylinder to form a detection space for the monitoring end.

[0018] Preferably, when one monitoring end of the differential pressure sensor (also the connecting end with the cigarette containing cylinder) is arranged on the bottom wall of the cigarette containing cylinder, the upstream substrate surface of the cigarette and the bottom of the cigarette containing cylinder can have no gap.

[0019] Preferably, the heated cigarette smoking set further comprises a heating element arranged around, at the bottom, or in the center of the cigarette containing cylinder. The heating element comprises a temperature controller and a power collector.

[0020] Preferably, the heated cigarette smoking set further comprises a data collector, a data storage, and a data analyzer.

[0021] The differential pressure sensor is sequentially connected in communication with the data collector, the data storage, and the data analyzer.

[0022] Preferably, the data analyzer is connected in communication with the temperature controller, and the temperature controller is used to control the output power of the heating element.

[0023] The present application provides a heated cigarette system, which comprises a heated cigarette and the heated cigarette smoking set of any one of the first aspect.

[0024] The heating cigarette comprises a smoking segment, an upstream end of the smoking segment is open, and the smoking segment is located in the cigarette accommodating cylinder.

[0025] In the present application, the flow direction of smoke is recorded as from upstream to downstream. The upstream end of the smoking segment is the end close to the bottom of the cigarette accommodating cylinder.

[0026] The heating cigarette further comprises a smoke mixing segment and a filter segment downstream of the smoking segment, the smoke mixing segment has a hollow structure, and the sidewall of the smoke mixing segment is provided with a sidewall through hole in communication with the hollow structure.

[0027] The cigarette accommodating cylinder is matched with the cigarette structure in function. Preferably, the cigarette accommodating cylinder is in a cylindrical shape.

[0028] The heating element can be selected from a resistance heating element, an infrared heating element, an electromagnetic heating element, a microwave heating element and the like. The heating element comprises other electrically driven heating elements and the like.

[0029] When the heating element is arranged at the center of the cigarette accommodating cylinder, it is in a rod-like or sheet-like structure.

[0030] Due to the addition of the pressure difference sensor, the heating cigarette apparatus can collect the following data: the working power of the heating element, the pressure difference between the space formed by the cigarette accommodating cylinder and the cigarette and the atmospheric pressure. The changes of the two kinds of data with the suction time can be collected and stored, and analyzed, so as to extract the smoking behavior characteristics of the consumer and used for subsequent heating element heating control.

[0031] The principle of the present application is as follows:

[0032] In operation, the cigarette is inserted into the cigarette accommodating cylinder, the heating element is started, and after preheating is completed, the cigarette is smoked. At this time, the smoking segment is heated to generate aerosol to form a positive pressure and move downstream. After the suction action is started, since the cigarette accommodating cylinder and the cigarette are directly sealed by the sealing member, the external air can and only can enter the smoke mixing segment through the sidewall through hole of the smoke mixing segment. Due to the high-speed fluid flow, a negative pressure is formed at the hollow structure of the smoke mixing segment, the aerosol generated by the smoking segment is transferred to the smoke mixing segment due to the action of the pressure difference, mixed with the air entering the place to form aerosol, and then transferred out of the smoke mixing segment under the action of the suction pressure difference of the user, to complete a suction. In a standard 55ml / 2s bell-shaped suction process, the negative pressure formed by the user suction is usually in the range of 500-3000pa. This pressure value exceeds the positive pressure formed by the aerosol of the smoking segment of the cigarette, so that the pressure difference sensor arranged on the upstream of the cigarette has a clear response. The response can be input, recorded and output through the data storage, and after the consumer completes the smoking of a cigarette, the apparatus also completes the recording of the smoking behavior of the consumer in the suction process.

[0033] Compared with the prior art, the utility model has the following beneficial effects:

[0034] The present application sets a pressure sensor in the cigarette accommodating cylinder of the closed heating cigarette smoking set. In the closed heating cigarette smoking set even without airflow channel, the pressure sensor records the suction behavior of the consumer when consuming the heating cigarette by recording the negative pressure formed during suction.

[0063] Figure 2 for Figure 1 Test data of the pressure sensor of the heated cigarette system under five different draw volumes were obtained. The experimental results were obtained by measuring the pressure drop at the bottom of the cigarette device under different draw volumes using a micro differential pressure gauge, a smoking machine, and a draw resistance meter. The operating temperature of the cigarette device was 260℃; the draw time was 2 seconds; and the draw volumes were 15mL, 25mL, 35mL, 45mL, and 55mL.

[0064] Figure 2 The data shows the pressure difference between the pre-aspiration stage and the aspiration stage over time. The pressure difference during the pre-aspiration stage remains approximately 0 Pa. The aspiration stage exhibits significant pressure difference changes. Therefore, data analysis can distinguish between the pre-aspiration stage and the aspiration stage, and the number of aspirations can be counted.
