Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smoking articles, in particular to a heating non-combustion type smoking set and a control method. BACKGROUND

[0002] Traditional cigarettes need to be ignited by open fire to produce tobacco smoke, and thousands of harmful substances to human body are released in the process of high temperature and cracking, which are composed of volatile substances existing in gas and semi-volatile and non-volatile substances existing in particles, such as carbon monoxide, phenols, aldehydes, nicotine, smoke tar, etc., while electronic cigarettes and low-temperature cigarettes can effectively reduce the generation of harmful substances, and the smoke of electronic cigarettes can simulate tobacco smoke, which is more healthy.

[0003] At present, the electronic smoking sets on the market mainly include two types, one is an electronic cigarette which forms a smoke that can be smoked by evaporating tobacco tar, and the other is a low-temperature cigarette which forms a smoke that can be smoked by distilling tobacco materials. When the low-temperature cigarette is used, a cigarette is inserted into a heating tube or a heating sheet of the smoking set, and then the power is turned on to make the heating tube / heating sheet heat, so that the cigarette is heated to generate smoke. The heating component is located in the interior of the smoking set. After a cigarette is smoked, the remaining part of the cigarette (a filter after smoking and residues) is taken out by grabbing the end of the cigarette exposed to the smoking set. Since the cigarette itself is heated, the tobacco inside the cigarette changes, so that the remaining tobacco and residues after heating often stick to the heating tube or the heating sheet. Therefore, how to reduce the problem of tobacco sticking to the heating body when the cigarette is pulled out is very important for the convenience of using the low-temperature smoking set. SUMMARY

[0004] The present application provides a heating non-combustion type smoking set and a control method to solve the problem that the remaining tobacco and residues after heating easily stick to the heating tube or the heating sheet.

[0005] In the first aspect of the present application, a heating non-combustion type smoking set is provided, which comprises system control devices, and switch devices, heating devices, driving devices, rotation number sensing devices and temperature sensing devices connected with the system control devices.

[0012] By increasing the driving device to drive the heating device to rotate spirally upward or downward, the heating device is made to enter the cigarette more labor-saving by controlling the motor in the driving device to drive the heating device to spiral displacement, so as to prevent the displacement of the tobacco fuel in the cigarette from blocking the airflow due to excessive force; after the heating and smoking of the cigarette are completed, the heating device is removed only after it is separated from the cigarette, which greatly reduces the residue of the residue generated in the heating process of the cigarette on the heating device; by increasing the rotation number sensing device, the rotation number of the rotating shaft of the motor in the driving device is collected in real time, the motor is controlled to stop working when the rotation number reaches the preset value, more accurate displacement control is realized, and the system is more stable during working; in addition, the temperature sensing device is additionally provided, the temperature of the heating device can be obtained in real time, the system control device can control the temperature of the heating device, and the temperature of the heating device can be stably increased to the target value and maintained.

[0017] The protruding features at two vertical ends of the push rod are arranged in the shape of an inclined surface, and an elastic feature in the same shape as the inclined surface is arranged on the side surface of the cigarette sleeve. After the cigarette is put in or taken out, when the motor rotates to drive the heating device to move towards the target, the push rod is simultaneously axially displaced. When the push rod is threadedly disengaged from the terminal gear connecting shaft of the reduction gearbox, the position of the push rod in the smoking set is kept by the spring at this moment.

[0054] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0055] like Figure 1As shown, the embodiment of the present application provides a heating non-combustion smoking set, which comprises a system control device 200, and a switch device 90, a heating device 401, a driving device 300, a rotation number sensing device 100, and a temperature sensing device 402 connected with the system control device 200;

[0056] The switch device 90 is used for receiving a smoking set switch action signal and sending a switch instruction to the system control device 200. Specifically, the switch device 90 is used for sending a switch-on / off instruction to the system control device 200, and the system control device 200 controls the start and stop of the smoking set and sends a driving instruction to the motor.

[0057] The heating device 401 is used for receiving a temperature control instruction of the system control device 200 and performing temperature rising / holding according to the temperature control instruction.

[0058] The driving device 300 is used for receiving a driving instruction of the system control device 200, triggering the motor in the driving device 200 to rotate forward or reversely by a preset number of turns, and driving the heating device 401 to rotate and displace at the same time.

[0059] The rotation number sensing device 100 is used for collecting the rotation number data of the motor in the driving device 300 in real time and sending the data to the system control device 200.

[0060] The temperature sensing device 402 is used for collecting the temperature data of the heating device 401 in real time and sending the data to the system control device 200, so that the system control device 200 determines the duty ratio and shutdown period of the heating device 401.

[0061] The system control device 200 is used for receiving the control instruction of the switch device 90 to control the start and stop of the smoking set, receiving the rotation number data sent by the rotation number sensing device 100 to generate a driving instruction for controlling the working state of the driving device 300 according to the rotation number data, and receiving the temperature data collected by the temperature sensing device 402 to generate a temperature control instruction for controlling the heating device 401 according to the temperature data. Specifically, the system control device 200 is used for receiving the switch instruction of the switch device 90 to perform corresponding start and stop operations, reading the real-time rotation number data of the rotation number sensing device 100 to determine whether the target data is reached according to the real-time information data, and then controlling the working state of the driving device 300, reading the real-time temperature data of the temperature sensing device 402 to generate a temperature control instruction and an instruction for powering on or off the heating device 401, and the heating device 401 is used for receiving the instruction and performing temperature rising / holding according to the instruction to heat the low-temperature cigarette.

[0062] The system, when running, first starts up, and after starting up, the system control device 200 starts working, sends driving instructions to the motor in the driving device 300, realizes the helical rotation of the driving device 300 to push the helical displacement of the heating device 401, and at the same time, opens the rotation number sensor 100 to start collecting the rotation number in real time. When the rotation number reaches the target value, the driving instruction is closed, and the temperature control instruction is opened to the heating device 401. After receiving the instruction, the heating device 401 starts to heat up, at the same time, the temperature sensing device 402 also starts to collect real-time information data, and sends the real-time information data to the system control device 200 in real time. The system control device 200 also generates a temperature control instruction to the heating device 401 according to the real-time information data, so that it is kept at a relatively constant temperature. When a cigarette is smoked (generally according to the set time), the system control device 200 generates a driving instruction to control the driving motor in the driving device 300 to rotate in the opposite direction, so that the helical rotation of the low-temperature smoking set heating device 402 is driven to move a certain distance in a straight line, and the rotation number sensing device 100 rotating synchronously with the motor in the driving device 300 collects the rotation number. When the target rotation number is reached, that is, the heating device 401 achieves the target displacement distance, the system control device 200 closes the driving instruction, and the motor stops working.

[0063] By increasing the driving device 300 to drive the heating device 401 to helically rotate upward or downward, and by controlling the motor in the driving device 300 to drive the heating device 401 to helically displace, the heating device 401 can enter the cigarette more labor-savingly, and the excessive stress of the tobacco fuel in the cigarette is prevented from causing displacement and blocking the airflow in the cigarette; after the cigarette is heated and smoked, the heating device 401 is removed only after it is separated from the cigarette, which greatly reduces the residue of the residue generated in the heating process of the cigarette on the heating device 401; by increasing the rotation number sensing device 100, the rotation number of the rotating shaft of the motor in the driving device 300 is collected in real time, and when the rotation number reaches the preset value, the motor is controlled to stop working, so that more accurate displacement control is realized, and the system works more stably; in addition, by additionally providing the temperature sensing device 402, the temperature of the heating device 401 can be obtained in real time, so that the system control device 200 can control the temperature of the heating device 401 to stably rise to the target value and maintain it.

[0064] Specifically, as shown in Figures 2 to 5 The system control device 200 comprises an information reading module 201, an information control module 202 and an instruction sending module 203 connected in sequence.

[0065] The information reading module 201 is used for obtaining the control instruction of the switch device 90 and the data collected by the rotation number sensing device 100 and the temperature sensing device 402, and sending the obtained control instruction and / or data to the information control module 202;

[0066] The information control module 202 is configured to process the control instructions and / or data acquired by the information reading module 201, generate control instructions, and send the control instructions to the instruction sending module 203.

[0067] The instruction sending module 203 is configured to send the control instructions generated by the information control module 202 to the driving device 300 and / or the heat generating device 401.

[0068] In the application scenario, the temperature sensing device 402 is a device such as a thermistor or a thermocouple, which is generally arranged on the heat generating body 401 of the low-temperature smoking set or integrated with the heat generating device 401 as a whole 400; the heat generating device 401 is generally one of a heating type tube heat generating body, a center heating type heating rod, and a heating sheet, and in the embodiment, the heat generating device 401 is a heating rod, and the temperature sensing device 402 is a thermistor.

[0069] The driving device 300 includes a motor 301, a reduction box 302 connected to one end of a rotating shaft of the motor 301, a U-shaped driving frame 305 connected to a protruding end shaft of an end gear of the reduction box 302, a reset support 306 connected to the U-shaped driving frame 305, and a screw rod 303. The reduction box 302 is configured to reduce the rotating speed of the motor 301 and increase the torque thereof. The U-shaped driving frame 305 is connected to the end gear connecting shaft of the reduction box 302 and rotates synchronously at the same speed. The reset support 306 is connected to the U-shaped driving frame 305 and rotates synchronously. The reset support 306 is fastened to one end of the screw rod 303 through a center hole arranged in the center of the reset support 306. The screw rod 303 is threadedly engaged with a nut 304 fastened to the shell. When the screw rod 303 and the reset support 306 rotate synchronously, the screw rod 304 and the reset support 306 rotate spirally around the nut 304 and axially displace due to the non-fastening and small gap cooperation between the U-shaped driving frame 305 and the reset support 306 and the similar cross section of the gap hole of the reset support 306 to the U-shaped driving frame 305. The heat generating device 401 connected to the other end of the screw rod 304 synchronously displaces. The reduction box 302 is arranged to reduce the rotating speed of the heat generating device 401, the rotating number sensing device 100 counts the rotating number of the motor, and the difference in the reduction speed of the two devices reduces the distance error in the movement control, thereby achieving more accurate displacement.

[0070] Motor 301 away from the end of the reduction gearbox shaft connected to the center hole of the cylindrical rotor 102, with motor 301 synchronous motion, in the rotor 102 center hole eccentric distance from the position set with blind hole, for fastening the magnet 103, can be fixed by riveting way magnet. On the circuit board set for sensing magnetic properties of the magnetic hall switch 101, magnetic hall switch 101 is higher than the circuit board electronic devices, its higher than the circuit board magnetic hall switch 101 is located in the rotor 102 set with blind hole side, and magnetic hall switch 101 and rotor 102, motor 301 end face and motor shaft between the gaps. System controller 200 instruction sending module 203 to give the drive instruction, control driver 300 drive heating device 401 spiral rotation displacement, motor 301 the other end of the rotating shaft when driving rotor 101 and the magnet 103 fixed on it rotates, in the movement process in a circle, the magnet 103 in eccentric position will have a moment close to the magnetic hall switch 101, the hall switch 101 will give the signal, by information reading module 201 record 1 times, when the record data reaches the target setting value, means that the motor 301 has driven the heating device 401 to reach the target position, by inductive motor rotation number to control the displacement of heating device 401, displacement control is more accurate. Information reading module 201 will feedback to information control module 202, by instruction sending module 203 to give the instruction, control to motor 301 power off, and at the same time to heating device 401 power supply, and temperature sensing device 402 starts to collect the temperature data of heating device 401. The data collected by temperature sensing device 402 is read in real time by information reading module 201 and analyzed by information control module 202, and the duty cycle is given in real time, so as to control the temperature of heating device 401 to approach the target trend, until the target value is reached. When the target value is reached, the system controller 200 will maintain the target temperature for the target time. When the target time is reached, the system controller 200 will power off the heating device 401, and send the drive instruction to the motor 301 by the instruction sending module 203 to drive the motor 301 to rotate reversely, drive the reduction gearbox 302, U-shaped drive frame 305, reset support 306, screw rod 303 movement, finally drive heating device 401 through nut 304 spiral rotation displacement, while the rotor 102 and magnet 103 rotate synchronously with the motor, and the magnetic hall switch 101 on the circuit board gives the rotation number signal, which is read by information reading module 201, when the target rotation number is reached, the system controller 200 controls the motor to power off, at this time the heating device 401 returns to the starting position, ready for the next work.

[0071] The embodiment also includes a cigarette locking mechanism, which includes a U-shaped push rod and a spring. The horizontal feature of the U-shaped push rod is provided with an internally threaded hole. The end gear connecting shaft of the reduction gearbox is provided with an externally threaded section. The front end of the connecting shaft is threadedly connected with the internally threaded hole of the push rod. The spring is coaxially arranged between the push rod and the end gear of the reduction gearbox, and the spring is in a compressed state.

[0072] When the motor rotates to drive the heating device to move towards the target, the push rod is simultaneously axially displaced. When the push rod is threadedly disengaged from the end gear connecting shaft of the reduction gearbox, the position of the push rod in the smoking set is maintained by the spring. At this position, the slope of the protruding features arranged at the two vertical ends of the U-shaped push rod clamps the cigarette holder to hold the cigarette. The motor continues to rotate to ensure that the heating device moves to the target position. After the cigarette is smoked, when the motor reverses rotation for a distance, the reset bracket contacts the push rod of the cigarette locking mechanism. The reset bracket will push the threads of the push rod to threadedly engage with the end gear connecting shaft of the reduction gearbox. When the motor rotates to drive the heating device to the starting position, the slope of the protruding features arranged at the two vertical ends of the U-shaped push rod releases the extrusion of the cigarette holder, i.e. releases the holding of the cigarette, and the user can remove the cigarette.

[0095] In use of the low-temperature smoking set, first, a cigarette is inserted into the smoking set, and then the smoking set is started. After the system control device obtains the start instruction, each part starts to work, including starting the motor to rotate, starting the rotation number sensing device to collect information and record data. When the motor rotates, the lock cigarette mechanism is driven to move towards the target position. When the first target data is reached, the heating device reaches the first target position. The lock cigarette mechanism is opened to lock the cigarette, and the lock cigarette mechanism is separated from the control of the motor. The motor continues to rotate. When the second target data is reached, it indicates that the heating device has reached the second target position, that is, it enters the cigarette. At this time, the motor is powered off and the heating device is powered on. The temperature sensing device is started to collect real-time temperature data. The duty cycle is adjusted in real time according to the data. When the heating time reaches the target value, it indicates that the smoking is completed. The heating body is powered off, and the motor is powered on to drive the motor to rotate in reverse and start the rotation number switch to collect information and record data. The lock cigarette mechanism starts to move reversely under the control of the motor. When the heating device reaches the first target position, the lock cigarette mechanism loosens the grip of the cigarette. The motor continues to rotate. When the working starting position is reached, it indicates that the heating device has separated from the cigarette. The motor is powered off, the heating body is stopped, the cigarette is removed, and the next work is prepared.

[0096] As Figure 8 shown, the application gives a specific embodiment of a control method of a heating non-combustion type smoking set system. It includes the following steps:

[0097] A10, obtaining a start instruction;

[0098] A15, presetting target rotation number information N1, N2;

[0099] A20, starting a driving instruction, starting the motor and the rotation number sensing device to work;

[0100] A25, judging whether the collected rotation number information reaches the target rotation number N1, N2;

[0101] A30, reach the target number of revolutions N1, the cigarette locking mechanism is started, and the cigarette locking mechanism holds the cigarette;

[0109] A85, preset the target number of revolutions N2-N1, N2;

[0110] A90, control the motor to reversely rotate according to the driving instruction, and simultaneously start the number of revolutions sensing switch counting;

[0111] A95, judge whether the collected real-time data information reaches the preset value N2-N1, N2;

[0112] A100, reach the target number of revolutions N2-N1, and the cigarette locking mechanism is loosened;

[0113] A110, reach the target number of revolutions N2, and close the motor rotation according to the driving instruction.

[0114] In the application process, first insert the cigarette, and then open the smoking set through the key switch to start working. After the system controller of the smoking set obtains the start-up instruction, the target rotation information N1 and N2 are set, i.e. the motor rotates N1 times to start the smoking set lock cigarette mechanism, and rotates N2 times to stop the motor. At the same time, the system controller drives the motor to rotate and push the heating device to spiral upward. The system controller will determine whether the number of rotations reaches N1 in real time. When N1 is reached, the smoking set lock cigarette mechanism is started to hold the cigarette. At the same time, the motor continues to rotate. When N2 is reached, the data is cleared, and the system controller turns off the motor power supply. Set the timing period t and the target temperature T. The timing period t refers to a working period of the smoking set system (for example, set the timing period to four minutes), i.e. a cycle from starting to automatically closing. The target temperature T refers to the target temperature interval of the heating body (for example, 200-260 degrees or 220-240 degrees, etc.). At the same time, generate the temperature control instruction and the real-time data information acquisition instruction. The temperature control instruction controls the heating device to start working and rising temperature. The real-time data information acquisition instruction refers to controlling the system to control the thermistor to start working and collecting the real-time information data of the thermistor feedback. When the heating body temperature rises to the target temperature T, the control system determines this conclusion according to the real-time information data of the thermistor feedback at this time, and starts to adjust the duty cycle of the heating body. By adjusting the duty cycle, the heating body is maintained in a relatively constant temperature interval, so that the cigarette in the low-temperature smoking set can be continuously and stably heated to generate aerosol for the user to smoke. When the timing period is completed, i.e. a working period is completed, the target rotation information N2-N1, N2 is set, and the control system drives the reverse motor to rotate to push the heating device to spiral downward. The real-time acquisition system will determine whether the number of rotations reaches N2 in real time. When N2 is reached, the motor pushes the heating body to the initial position, and the smoking set enters the dormant state to prepare for the next cigarette.

[0115] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

The system controller controls the motor to work, which drives the gearbox to rotate. The gearbox drives the U-shaped drive frame to rotate synchronously. The U-shaped drive frame drives the reset bracket to rotate synchronously. The reset bracket drives the screw to rotate synchronously, thereby causing the screw to rotate and move in a spiral motion, which in turn drives the heating element to rotate and move in a spiral motion. It also includes a smoke-locking mechanism, which includes a U-shaped push rod and a spring. The push rod has an internal threaded hole at the horizontal feature position of the U-shape. The front end of the gear connecting shaft of the gearbox has an external thread. The front end of the connecting shaft is threadedly connected to the internal threaded hole of the push rod.

The protruding features at the two vertical ends of the U-shaped push rod are designed with a beveled shape. These protruding features contact the outer surface of the cigarette sleeve. Correspondingly, the side of the cigarette sleeve has an elastic feature with a similar beveled shape. After the cigarette is inserted, when the motor rotates and pushes the heating element towards the target, the push rod simultaneously moves axially. When the push rod disengages from the threaded connection shaft of the gearbox's end gear, the spring maintains the push rod's current position in the cigarette device. At this position, the beveled features at the two vertical ends of the push rod's U-shape drive the cigarette sleeve to hold the cigarette tightly.
