Description

TECHNICAL FIELD

[0001] The present application belongs to the field of research and determination of heat-not-burn cigarettes, and relates to a heat-not-burn cigarette holder and starting device and method. BACKGROUND

[0002] In conventional cigarette research, smoking machines and other smoke suction devices are often used for cigarette smoke suction analysis. These devices usually have a row of suction holes, and multiple conventional cigarettes can be directly inserted into the suction holes and ignited by an ignition device for suction analysis.

[0003] With the rise of heat-not-burn cigarette research, it is necessary to use the above-mentioned cigarette suction equipment for automatic suction analysis test of heat-not-burn cigarettes. However, the suction method of heat-not-burn cigarettes is completely different from that of conventional cigarettes. Conventional cigarettes can be suctioned after being ignited, while heat-not-burn cigarettes need to be placed in a specific heatable holder for heating and suction at the same time. This results in the fact that heat-not-burn cigarettes cannot be directly inserted into the suction holes of the test device like conventional cigarettes, and an additional device is needed to hold the holder to keep the heat-not-burn cigarettes stably inserted into the suction holes. This device also needs to have the function of starting the holder. Therefore, there is an urgent need for a matching holder holding and starting device to meet the needs of efficient and accurate heat-not-burn cigarette suction test. CN222050118U proposes a heat-not-burn cigarette smoke detection holding device, but only supports single holder operation and the holding force is not adjustable, which cannot adapt to the special-shaped holder with asymmetric ends. This device needs to be manually pressed to start, which cannot meet the needs of efficient analysis. CN110333109A invents a heat-not-burn cigarette lighting and smoke capturing device, which adopts a multi-channel suction structure. The trigger lever is pressed by a gas cylinder to press the holder button, realizing the synchronous starting of multiple holders. It can realize the starting and smoke capturing of multiple heat-not-burn cigarette holders, but the trigger lever needs to rely on the linkage of an external air pump and a gas cylinder, so the device is bulky and difficult to be compatible with small laboratory suction equipment. No holder fixing module is designed, and the holder is easy to deviate during testing, resulting in inaccurate alignment of the suction hole. The patent does not mention the technical content of different holder holding and starting, and obviously cannot meet the needs of combining with existing smoke suction equipment to realize efficient test of heat-not-burn cigarette smoke.

[0004] In summary, the technical solutions in the prior art still have the following defects:

[0005] 1. Insufficient versatility of holding: mechanical limiting or elastic clamping is difficult to adapt to complex holder shapes;

[0006] 2. Lack of protection for the holder: conventional mechanical holding design is easy to damage the surface of the holder;

[0007] 3. Start-up synchronization is poor: relying on manual or step-by-step operation, unable to meet the needs of parallel testing of multiple smoking devices;

[0008] 4. Low system integration: lack of linkage control between clamping, starting and smoking equipment, limited test efficiency. SUMMARY

When starting, compressed air is filled in the inner tube 2-5. Under the action of air pressure, the starting head 2-6 rises along the inner tube 2-5 and presses against the starting button of the heated but not burning cigarette set 4 to start the set. After starting, the starting head gas switch valve 3-31 is disconnected from the compressed air and connected with the external air.

The height feet 6 are connected with the main support 1 through threads at the upper part. The height of the whole device is adjusted by rotating, so that the filter tip of the heated but not burning cigarette in the clamped set is aligned with the suction hole. The threads have a small pitch, such as 1 mm, so as to continuously and precisely adjust the height of the main body. The height precision is 0.1 mm. The lower part of the height feet 6 is a large cylinder, so as to ensure the stability of the whole device. The bottom is provided with an anti-skid layer, so as to further improve the stability when the device is placed and used.

[0058] A method for clamping and starting a heat-not-burn cigarette smoking set by using the device of example 1, comprising the following steps:

[0059] S1. Main support positioning: fix or place the main support 1 in front of the suction hole of the suction equipment, adjust the direction of the dovetail groove guide rail 1-1, and adjust the height of the height foot 6, so that the mouthpiece of the heat-not-burn cigarette 5 to be tested is opposite to the suction hole of the suction device;

[0060] S2. Smoking set clamping: insert the heat-not-burn cigarette 5 into the smoking set 4, and place the smoking set 4 between the clamping columns 2-2 of the clamping and starting block 2, and make the starting button downward, and adjust the left and right positions of the clamping and starting block 2, and correctly put the mouthpiece of the heat-not-burn cigarette 5 into the suction hole, then press the corresponding clamping button on the control device 3, and fill 0.1-0.3 MPa compressed air into the clamping air bag 2-3 through the control device 3, the clamping force is stable at 5-15 N, and the heat-not-burn cigarette smoking set 4 is clamped and fixed;

[0061] S3. Start head positioning: push the start head position handle 2-4 to move the starting part, so that the start head 2-6 is opposite to the starting button of the heat-not-burn cigarette smoking set 4, and then put and clamp other heat-not-burn cigarette smoking sets 4 with the same or different shapes in sequence, and adjust the corresponding start head position;

[0062] S4. Start the smoking set: after receiving the start signal of the smoking device, the control device 3 drives all the start heads 2-6 to rise and press the buttons at a gas pressure of 0.2-0.5 MPa, triggering the heating;

[0063] S5. Release: after the start of the heat-not-burn cigarette smoking set 4, the control device 3 receives the completion signal and sends a command to the start head gas switch valve 3-31, which is disconnected from the compressed air and connected to the external air, so that the gas pressure in the inner tube 2-5 returns to normal pressure and no additional pressure is generated, the pressure of the start head 2-6 on the start button is released, the smoking set button rebounds, and the normal heating state is entered;

[0064] S6. Test and completion: the control device 3 feeds back the completion signal to the smoking device, starts the smoke suction analysis test at the same time, releases the pressure of the clamping air bag 2-3 after the test is completed, and takes out the smoking set.

[0065] Example 2 provides a heat-not-burn cigarette smoking set clamping and starting device, and the different parts from Example 1 are particularly described as follows:

[0066] The clamping air bag 2-3 in Example 2 is made of rubber, the spacing of the clamping columns 2-2 is 14 mm, the diameter of the semi-cylindrical tube body of the clamping air bag 2-3 after expansion is 10 mm, and the spacing of the clamping air bag 2-3 is suitable for the width or diameter of the smoking set of less than 14 mm.

[0067] In Example 2, the control device 3 takes a microcontroller (MCU) as the core control unit, integrates a communication module, an electromagnetic valve driving circuit, a pressure sensor and feedback circuit, and a human-computer interaction interface, and realizes precise control of the clamping and starting process.

[0068] The core control unit adopts a high-performance MCU, analyzes the input touch panel settings and smoking device instruction signals through program logic, outputs PWM or digital signals to control the execution elements, and receives the feedback signals of the pressure sensor through the built-in A / D conversion module, forming a closed-loop control to maintain the set gas pressure.

[0069] The communication module circuit adopts an RS-485 interface, realizes serial communication with the electromagnetic valve driving board and touch panel inside the control device 3 through a MAX485 chip, supports multi-node data interaction; the CAN bus interface adopts a MCP2515 CAN controller and a TJA1050 transceiver, establishes high-speed communication with the smoking device, realizes real-time interaction of the start signal and state feedback.

[0070] The electromagnetic valve driving circuit adopts a MOSFET power driving chip to receive digital signals of the MCU and control the on-off of multiple independent electromagnetic valves. Each electromagnetic valve corresponds to an independent overcurrent protection circuit to avoid damage caused by overload and support independent control of a single smoking set or linkage of multiple smoking sets. A high-precision pressure sensor is connected in series in the gas circuit to convert the gas pressure signal into a 0-5V analog signal, which is input to the A / D port of the MCU after RC filtering. The MCU adjusts the opening of the starting head gas regulating valve 3-21 and the clamping part gas regulating valve 3-22 according to the deviation between the set pressure and the feedback value through the PID algorithm to realize accurate control of the gas pressure. The touch panel is connected with the MCU through an I2C interface to support setting of the gas pressure parameters, with the clamping gas pressure set to 0.1-0.3MPa and the starting gas pressure set to 0.2-0.5MPa, support adjustment of the starting time and switching of the working modes, including single smoking set and multiple smoking sets. The status indicator light displays the system status in real time through LEDs, including standby, clamping, starting, and fault.

[0071] The external compressed air enters the control device 3 through a pressure reducing valve, passes through a water separation and gas filter to remove impurities and moisture, ensures the cleanliness of the gas circuit, and is reduced to the set value of 0.1-0.3MPa by the clamping part gas regulating valve 3-22, then is distributed to each clamping air bag 2-3 through the clamping part gas switch valve 3-32. After the clamping air bag 2-3 is inflated and expanded, a clamping force of 5-15N is generated. A pressure sensor is arranged in the clamping air bag 2-3 to monitor and feedback to the MCU in real time, and the gas pressure is dynamically adjusted to adapt to different shapes of the heat-not-burn cigarette smoking set 4. The compressed air is reduced to 0.2-0.5MPa by the starting head gas regulating valve 3-21, and is distributed to each starting head inner tube 2-5 through the starting head gas switch valve 3-31. The gas pressure drives the starting head 2-6 to vertically press the smoking set button with a stroke of 1-15mm, the response time is ≤0.1s, and the pressing force error is <1%.

[0072] In example 2, a plurality of electromagnetic valve arrays are adopted, each corresponding to a clamping unit and a starting unit, supporting simultaneous control of multiple heat-not-burn cigarette smoking sets 4. The MCU distinguishes different channels through address coding to realize independent gas pressure adjustment and synchronous starting control.

[0075] S2. Clamping of the smoking set: Insert the heat-not-burn cigarette 5 into the smoking set 4, and place the smoking set 4 between the clamping columns 2-2 of the clamping starting block 2, and make the starting button downward, and adjust the left and right positions of the clamping starting block 2, so as to correctly place the mouthpiece of the heat-not-burn cigarette 5 into the suction hole;

[0077] S4. Starting of the smoking set: the operator sets parameters such as clamping air pressure and starting pressure through the touch panel, and the MCU synchronizes the parameters to the suction equipment database; after the suction equipment is ready, the "starting instruction" is sent through the CAN bus, and the frame format of the starting instruction contains the equipment ID and the starting time; after the control device 3 receives the instruction, the starting head gas switch valve 3-31 is driven to open, the air pressure drives the starting head 2-6 to press the button, and the heat-not-burn cigarette smoking set 4 is triggered to heat; after the starting is completed, the control device 3 sends a "starting confirmation signal" to the suction equipment, which contains the actual starting time and the state signal of each smoking set;

[0078] S5. Release: after the heat-not-burn cigarette smoking set 4 is started, the control device 3 receives the starting completion signal, and sends an instruction to the starting head gas switch valve 3-31, the starting head gas switch valve 3-31 is disconnected with the compressed air, and connected with the external air, the air pressure in the inner tube 2-5 returns to normal pressure, and no additional pressure is generated, the pressure of the starting head 2-6 on the starting button is released, the smoking set button rebounds, and enters the normal heating state;

[0079] S6. Test and completion: after the suction equipment receives the "starting confirmation signal", the suction of the smoke starts, and the "suctioning" state signal is sent to the control device 3; the control device 3 continuously monitors the pressure of the clamping air bag 2-3 during the suction process, and if the pressure fluctuation exceeds ±0.02 MPa, the pressure is automatically supplemented to maintain stable clamping; the control device 3 uploads the clamping force, starting pressure, synchronization time and other data of this test to the laboratory management system through the RS-485 interface, and forms a test report; after the suction test is completed, the suction equipment sends a "test end" signal to release the pressure of the clamping air bag 2-3.
