DETAILED DESCRIPTION

[0032] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods.

[0033] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0034] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0035] like Figure 1 As shown, a heating non-combustion device provided in this embodiment includes a heating component 10 and a main body 20; wherein the heating component 10 includes a first control structure 13 and a heating element 11, and the first control structure 13 is used to supply power to the heating element 11 according to a preset program under the triggering of a heating signal to control the heating of the heating element 11; the heating element 11 is electrically connected to the first control structure 13, and the heating element 11 is used to heat the aerosol generating matrix 30 under the control of the first control structure 13.

[0036] The main body 20 is detachably connected to the heating assembly 10, and the main body 20 includes a second control structure 23 and a battery 21, and the battery 21 is used to supply power to the second control structure 23; the second control structure 23 is electrically connected to the first control structure 13, and the second control structure 23 is used to supply power to the first control structure 13, and the second control structure 23 is also used to send a heating signal to the first control structure 13 according to the user's instructions.

[0037] Specifically, when working, first, after the heating non-combustion device is turned on, the user gives the second control structure 23 a heating instruction, and the second control structure 23 sends a heating signal to the first control structure 13 after receiving the instruction. Then, the first control structure 13 supplies power to the heating element 11 according to a preset program under the triggering of the heating signal, so that the heating element 11 can heat the aerosol generating matrix 30 according to a preset heating curve. Among them, the second control structure 23 is powered by the battery 21. Since the second control structure 23 and the first control structure 13 are electrically connected, the first control structure 13 can be powered by the second control structure 23. In actual application, the first control structure 13 and the second control structure 23 respectively use PCB main boards as control boards. The heating signal sent by the second control structure 23 to the first control structure 13 is a level alternating signal. Moreover, when heating, since the resistance between the spring pins 22 is relatively large, if the second control structure 23 is used as the main control board, during the heating control process, the contact resistance between the spring pin 22-copper column 12 structure will affect the normal heating of the heating element 11, resulting in a reduction in the heating effect. Therefore, this scheme uses the second control structure 23 as the main control board to control the heating element 11 for heating.

[0038] Furthermore, for the heating component 10, a heat insulating member, such as a heat insulating cotton or a heat insulating board, may be provided between the heating element 11 and the first control structure 13 to ensure that the temperature of the first control structure 13 during the heating process is always lower than 85°C, thereby ensuring that the first control structure 13 can work normally and also extending its service life.

[0039] By adopting the heating-not-burning device of this embodiment, it is possible to achieve communication between split heating-not-burning devices and precise temperature control heating, thereby meeting the high adaptability of aerosol generating substrates 30 of different specifications to the device itself, and effectively improving the utilization rate of the device. By adopting the communication method between the heating component 10 and the main body 20 of the present application, the main body can control the temperature of the heating element in the heating component 10, can identify the differences between different modules, and maintain the normal operation of the modular HNB (heating-not-burning) device.

[0040] In some embodiments, Figure 2 and Figure 3 As shown, the main body 20 also includes an airflow sensor 24; the airflow sensor 24 is electrically connected to the second control structure 23; the airflow sensor 24 is used to generate an air pressure signal after the suction action occurs; the second control structure 23 is also used to send a heating signal to the first control structure 13 under the triggering of the air pressure signal.

[0041] In practical applications, the airflow sensor 24 uses a microphone. Specifically, when the heating reaches a preset time, the user is reminded to start inhaling. When the user takes a puff, the air pressure signal generated by the airflow sensor 24 changes. At this time, after sensing the change in air pressure, the second control structure 23 sends a heating signal to the first control structure 13. The first control structure 13 adjusts the current input to the heating element 11 according to the heating signal to adjust the temperature of the heating element 11 at different times.

[0042] Furthermore, in some embodiments, the heating-not-burning device further includes a plurality of spring pins 22 and a plurality of copper pillars 12 arranged corresponding to the spring pins 22; wherein the spring pins 22 are arranged on the body 20, and the spring pins 22 are connected to the second control structure 23; the copper pillars 12 are arranged on the heating component 10, and the copper pillars 12 are connected to the first control structure 13; the second control structure 23 communicates with the first control structure 13 and / or supplies power through the spring pins 22 and the copper pillars 12. Alternatively, the spring pins 22 may be arranged on the heating component 10, and the spring pins 22 are connected to the first control structure 13; the copper pillars 12 are arranged on the body 20, and the copper pillars 12 are connected to the second control structure 23; the second control structure 23 communicates with the first control structure 13 and / or supplies power through the spring pins 22 and the copper pillars 12.

[0043] In this embodiment, Figure 2 and Figure 3 As shown, it can be seen that the heating component 10 and the main body 20 rely on the elastic pins 22 for power supply and communication. Specifically, in this solution, four elastic pins 22 are provided on the main body 20, and four copper pillars 12 are provided at positions of the heating component 10 corresponding to the elastic pins 22. When in use, three elastic pins 22-copper pillar 12 structures are used for power supply, and one elastic pin 22-copper pillar 12 structure is used for communication. Alternatively, the elastic pin 22 is provided on the heating component 10, and the copper pillar 12 is provided at the position of the main body 20 corresponding to the elastic pin 22, and the use principle is the same. In addition, the number of the elastic pin 22-copper pillar 12 structures is set to at least 2, and is generally between 2 and 16.

[0044] It should be noted that the connection structure of the spring pin 22-copper column 12 can also be replaced by other pluggable connectors, such as a terminal end-type connection structure, a pin-and-socket type connection structure, or a threaded type connection structure. This connection structure can not only realize the communication between the heating component 10 and the body 20, but also ensure the power supply to the heating element 11.

[0045] In some embodiments, Figure 1 As shown, the main body 20 also includes a display unit 25, which is electrically connected to the second control structure 23; the second control structure 23 is also used to receive and process the display signal sent by the first control structure 13, and send the processed display signal to the display unit 25 for display.

[0046] Specifically, the display unit 25 is a display screen. During the working process, in order to facilitate the user to grasp the current use status of the device at any time, the first control structure 13 will send a display signal to the second control structure 23 at different stages of the heating process, such as a signal to remind the user to start inhaling when the heating reaches a preset time. The second control structure 23 processes the signal and displays it through the display unit 25 to remind the user of the current use status.

[0047] In some embodiments, Figure 1 As shown, the body 20 further includes a button 26 , which is electrically connected to the second control structure 23 , and the user's instructions are transmitted to the second control structure 23 via the button 26 .

[0048] Furthermore, a button 26 is provided on the body 20, and the user transmits the instruction to the second control structure 23 by pressing the button 26, and then the second control structure 23 transmits the signal to the first control structure 13 to perform the corresponding operation. For example, pressing once represents the instruction to start the smoking device, and pressing twice in succession represents the instruction to start heating, etc.

[0049] Furthermore, as a control method for stopping heating, the second control structure 23 is provided with a preset heating time or a preset number of puffs; when the heating time of the heating element 11 reaches the preset heating time, the second control structure 23 sends a signal to stop heating to the first control structure 13. Alternatively, when the number of times the air pressure signal is generated reaches the preset number of puffs, the second control structure 23 sends a signal to stop heating to the first control structure 13.

[0050] Specifically, before the heating-not-burning appliance leaves the factory, a preset heating time or a preset number of puffs is set in the second control structure 23. After leaving the factory, during the user's use, when the temperature control and heating stage reaches the total preset time, the second control structure 23 will send a signal to stop heating to the first control structure 13. At this time, the first control structure 13 stops supplying current to the heating element 11 after receiving the signal. Alternatively, the second control structure 23 is provided with a counter, which records the number of times the heating signal sent by the airflow sensor 24 is received. When the number reaches the preset number of puffs, the second control structure 23 sends a signal to stop heating to the first control structure 13. At this time, the first control structure 13 stops supplying current to the heating element 11 after receiving the signal, and the appliance ends heating.

[0051] As another control method for stopping heating, the first control structure 13 is provided with a preset heating time or a preset heating number; when the heating time of the heating element 11 reaches the preset heating time, the first control structure 13 controls the heating element 11 to stop heating. Alternatively, when the number of heating signals sent by the second control structure 23 to the first control structure 13 reaches the preset heating number, the first control structure 13 controls the heating element 11 to stop heating.

[0052] Specifically, before the heating-not-burning appliance leaves the factory, a preset heating time or a preset number of heating times is set in the first control structure 13. After leaving the factory, during the user's use, according to the preset program, when the temperature control heating stage reaches the total preset time, the first control structure 13 will stop supplying current to the heating element 11. Alternatively, the first control structure 13 is provided with a counter, which records the number of heating signals sent by the second control structure 23. When the number reaches the preset number of heating times, the first control structure 13 will stop supplying current to the heating element 11, and the appliance will end heating.

[0053] Another heating non-combustion device provided in this embodiment includes a heating component 10 and a main body 20; the heating component 10 includes a first control structure 13 and a heating element 11; wherein the first control structure 13 is used to store the heating parameters of the heating element 11; the heating element 11 is used to heat the aerosol generating matrix 30; the main body 20 and the heating component 10 are detachably connected, and the main body 20 includes a second control structure 23 and a battery 21, and the battery 21 is used to supply power to the second control structure 23; the second control structure 23 is electrically connected to the first control structure 13 and the heating element 11, respectively, and the second control structure 23 is used to obtain the heating parameters from the first control structure 13, and supply power to the heating element 11 according to the heating parameters to control the heating of the heating element 11.

[0054] In the heating-not-burning device of this embodiment, when the memory space of the first control structure 13 is small, the first control structure 13 is used as a storage chip, and the second control structure 23 is used as the main control board to control the heating of the heating element 11. Specifically, the heating parameters of the heating element 11 are acquired and stored in real time by the first control structure 13, wherein the heating parameters are the parameters of the heating element 11 itself, mainly including the resistance value, temperature, and the corresponding relationship between the resistance value and the temperature of the heating element 11. For example, how much the resistance value of the heating element 11 will increase when the heating element 11 rises by one degree is read (which can be calculated by the TCR formula). Since there is a communication connection between the first control structure 13 and the second control structure 23, the first control structure 13 can send the acquired heating parameters to the second control structure 23, and the second control structure 23 will determine the corresponding heating curve according to the heating parameters, and then supply the corresponding current of the heating element 11 to achieve temperature control heating of the aerosol generating matrix 30. In addition, as in the above embodiment, the second control structure 23 is also powered by the battery 21, and the first control structure 13 is powered by the second control structure 23.

[0055] Similarly, the heating component 10 and the body 20 of this embodiment also communicate / power supply through the spring pin 22-copper pillar 12 structure. The specific implementation principle has been described in detail in the above embodiment, and this embodiment will not be repeated here. At this time, it is necessary to ensure that the contact resistance of the spring pin 22-copper pillar 12 structure during heating is not greater than 50 milliohms to ensure that the heat loss is within the expected range.

[0056] The detachable connection method mentioned in the above embodiment can be one of the following connection methods: magnetic connection, snap connection, threaded connection and pin connection. This embodiment is described by taking magnetic connection as an example. Figure 2 As shown, two or more upper magnets 14 are provided at the bottom of the heating component 10, and a lower magnet 27 is provided at the position where the main body 20 is connected to the heating component 10, wherein the positions and quantities of the upper magnets 14 and the lower magnets 27 correspond to each other. When assembling the appliance, the lower magnets 27 and the lower magnets 27 are magnetically connected to each other, thereby realizing the assembly of the heating-not-burning appliance. When the detachable connection method is a threaded connection, the heating component 10 can be screwed into the main body 20; when the detachable connection method is a pin connection, the pin provided in the main body 20 can be inserted into the corresponding pin hole of the heating component 10, or the pin provided in the heating component 10 can be inserted into the corresponding pin hole of the main body 20. The specific implementation method can be realized by the existing technology, and this embodiment does not require too much here.

[0057] In addition, the heating without burning appliance of this embodiment can also adopt the arrangement method of the above-mentioned embodiment in terms of structural arrangement, and this embodiment will not be described in detail here.

[0058] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
