Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization, in particular to a control system and method for locking oil and wetting a wick of an atomization device. BACKGROUND

[0002] A large-capacity electronic cigarette in the prior art includes a main body and an oil tank. The main body has a support, a battery, and a circuit board. The battery and the circuit board are assembled in the support. The battery is connected to the circuit board through a wire. The main body has an opening at the upper portion. The oil tank is arranged in the opening. The oil tank is provided with an atomization tube and tobacco tar. The upper portion of the oil tank is provided with a mouthpiece. The atomization tube is provided with a storage cotton and an atomization assembly. The upper end of the atomization tube is connected to the mouthpiece. The lower end of the atomization tube is connected to an air inlet hole. The capacity of the oil tank is generally 10 ml, 15 ml, 20 ml, 25 ml, etc. The atomization tube is provided with an oil inlet hole. A switch valve is arranged at the oil inlet hole. The atomization tube is provided with a storage cotton on the inner side. The storage cotton is circular and hollow. The storage cotton is wrapped around the outer side of the atomization assembly. The atomization assembly includes a steel tube. The upper and lower ends of the steel tube are open. The side wall of the steel tube is provided with a clamping groove. The steel tube is provided with a heating wire and a guide cotton. The steel tube is provided with a liquid inlet hole. The guide cotton is wrapped around the heating wire in a cylindrical shape. The outer side of the guide cotton abuts against the inner side of the steel tube. The heating wire is located on the inner side of the guide cotton. The tobacco tar flows into the storage cotton through the oil inlet hole. The tobacco tar in the storage cotton flows into the guide cotton through the liquid inlet hole and reaches the inner side of the guide cotton. The heating wire is connected to the circuit board through a wire. The circuit board controls the output power of the battery to the heating wire. The heating wire heats the tobacco tar on the guide cotton into smoke. The air from the outside flows into the air inlet hole, flows upward along the atomization tube, and then flows upward through the steel tube to reach the heating wire. The heating wire carries away the smoke and the smoke flows out from the steel tube, the atomization tube, and the mouthpiece.

[0003] The large-capacity oil tank is generally not pre-filled with tobacco tar. The oil tank is empty and does not contain tobacco tar. When the oil tank is used for the first time, the tobacco tar needs to be injected into the oil tank. Since the tobacco tar in the oil tank needs to flow into the storage cotton through the oil inlet hole and then flow into the guide cotton through the liquid inlet hole, the path of the tobacco tar is relatively long. Therefore, when the tobacco tar is injected into the oil tank for the first time, the valve needs to be opened and a period of time needs to be waited, for example, 1-2 minutes. After the tobacco tar is fully injected into the guide cotton, the user can normally smoke and the heating wire can be powered to heat the tobacco tar into smoke. If the user smokes immediately after the tobacco tar is injected, the valve is opened at the same time, but the tobacco tar has not been fully injected into the guide cotton or the tobacco tar has not been injected into the guide cotton at all. The heating wire is dry and is easy to burn the guide cotton.

[0004] Therefore, it is necessary to provide a control system and method for locking oil and wetting a wick of an atomization device to overcome the above-mentioned defects. SUMMARY

[0005] The main purpose of the present application is to provide a control system and method for locking oil and wetting wick of an atomization device, which can provide sufficient tobacco tar for the atomization assembly at the first use, lock oil when not in use, and prevent dry burning effect of the atomization assembly.

[0006] To achieve the above purpose, the present application provides a method for locking oil and wetting wick of an atomization device, comprising the following steps:

[0007] a. providing an atomization device, the atomization device comprising a main machine and a cartridge, the main machine being provided with a battery and a circuit board, the circuit board being connected to the battery, the cartridge being provided with a chip, an oil tank, a valve, an atomization assembly and a moving assembly;

[0008] b. connecting the main machine and the cartridge, the main machine detecting whether the cartridge is a cartridge that has not been wetted or a cartridge that has been wetted, if the cartridge is a cartridge that has not been wetted, initializing the payload of the chip as M by the circuit board, and writing the payload M into the chip; if the cartridge is a cartridge that has been wetted, directly analyzing the payload data N in the chip, and recording N in the circuit board, N < M, if N = 0, marking the cartridge as a cartridge that has been wetted completely, if N ≠ 0, marking the cartridge as a cartridge that has not been wetted completely;

[0009] c. for the cartridge that has been wetted completely, when suction is performed from the suction nozzle of the cartridge, the circuit board informs the moving assembly to open the valve, the tobacco tar in the oil tank flows to the atomization assembly through the valve, the circuit board informs the atomization assembly to start atomizing the tobacco tar, and normal suction can be performed; for the cartridge that has not been wetted completely and the cartridge that has not been wetted, when suction is performed from the suction nozzle of the cartridge, the circuit board informs the atomization assembly not to atomize the tobacco tar, and step d is entered;

[0010] d. for the cartridge that has not been wetted, the circuit board informs the moving assembly to open the valve, and simultaneously starts a timing / counting function, from the opening to the closing of the valve, which is defined as a time length T, every time the time length T is passed, the circuit board changes the payload data of the chip to M-1 and stores it in the chip, until M = 0, and then normal suction can be performed; for the cartridge that has not been wetted completely, the circuit board informs the moving assembly to open the valve, and simultaneously starts a timing / counting function, every time the time length T is passed, the circuit board changes the payload data of the chip to N-1 and stores it in the chip, until N = 0, and then normal suction can be performed.

[0011] The host detects whether the cartridge is an unprimed cartridge or a primed cartridge by the following method: after the chip is powered on, the circuit board starts reading the data information of the chip through the signal line, and the data format and the verification mode are pre-stored in the circuit board. If the read data information of the chip does not conform to the pre-stored data format and verification mode, the cartridge is marked as an unprimed cartridge. If the read data information of the chip conforms to the pre-stored data format and verification mode, the cartridge is marked as a primed cartridge.

[0012] Defining M as the number of times of priming required, if M=0, it indicates that the number of times of priming required is zero, and normal smoking can be directly performed. Defining N as the number of times of priming required, if N=0, it indicates that the number of times of priming required is zero, and normal smoking can be directly performed. If N≠0, it indicates that the number of times of priming required is N, and normal smoking can be performed after the number of times of priming is completed.

[0013] When smoking from the nozzle of the cartridge, the circuit board first detects whether the cartridge is an unprimed cartridge or a primed cartridge. For a primed cartridge, normal smoking can be performed. For an unprimed cartridge and a cartridge that has not been primed completely, the circuit board informs the atomization assembly not to atomize the tobacco oil, and the circuit board informs the movement assembly to periodically open and close the valve until the number of times of priming is completed.

[0014] From the opening of the valve to the closing of the valve, a time length T is one time of priming. For an unprimed cartridge, if the cartridge is separated from the host during the Kth time of priming, the cartridge has been primed K-1 times, the circuit board records that the cartridge has been primed K-1 times, the circuit board changes the payload data of the chip to M-(K-1), and stores M-(K-1) in the chip, indicating that the cartridge still needs to be primed M-(K-1) times to perform normal smoking.

[0015] From the opening of the valve to the closing of the valve, a time length T is one time of priming. For a cartridge that has not been primed completely, the circuit board changes the payload data of the chip to N-1 and stores N-1 in the chip after each time of priming is completed. The priming action is repeated N times, the circuit board continuously changes the payload data of the chip to 0, and N=0 is stored in the chip, indicating that the cartridge has been primed completely and normal smoking can be performed.

[0016] The host is also provided with a display screen. For an unprimed cartridge, the display screen starts to display a normal working state until M=0. For a cartridge that has not been primed completely, the display screen starts to display a normal working state until N=0.

[0024] When the read-write unit detects that the time length of remaining wetting cores or the number of remaining wetting cores of the storage module is 0, the cartridge is marked as a cartridge whose wetting cores have been completed, and for the cartridge whose wetting cores have been completed, the main control module informs the atomization assembly to heat according to the electrical signals of the induction module;

[0025] When the read-write unit detects that the time length of remaining wetting cores or the number of remaining wetting cores of the storage module is greater than 0, the cartridge is marked as a cartridge whose wetting cores have not been completed, and for the cartridge whose wetting cores have not been completed, the main control module informs the atomization assembly not to heat.

The upper part of the cartridge 1 is provided with a mouthpiece, the lower part of the cartridge 1 is provided with an air inlet hole, the cartridge 1 further comprises an oil tank 11, the mouthpiece and the air inlet hole are provided with an atomization tube, the sidewall of the atomization tube is provided with a valve 12, the valve 12 is also called an oil inlet hole, the atomization tube is provided with a steel pipe, the steel pipe is provided with an atomization assembly 15, the atomization assembly 15 comprises an oil guide body 16 and a heating body 17, the oil guide body 16 can be oil guide cotton, porous ceramic and the like, the heating body 17 is a heating wire, a heating sheet, a heating net, a heating film and the like, the oil guide body 16 is used for transmitting tobacco tar, the heating body 17 is used for heating the tobacco tar into smoke, the two ends of the heating body 17 are connected with the circuit board through wires, the battery is connected with the circuit board, the electromagnet 21 is connected with the circuit board, the airflow sensor is connected with the circuit board, when the mouthpiece is smoked, the gas in the air inlet channel flows, the airflow sensor senses the change of air pressure, the airflow sensor sends an electric signal to the circuit board, the circuit board transmits the electric energy of the battery to the heating body 17, the heating body 17 generates heat after being electrified, the tobacco tar adsorbed on the inner side of the oil guide body 16 is heated into smoke, the smoke flows upwards along the atomization tube, after the outside air enters the air inlet channel and then enters the air inlet hole, the outside air flows upwards along the atomization tube and enters the lower end of the steel pipe, the outside air and the smoke continue to flow upwards after being mixed, from the lower end of the steel pipe, then enter the atomization tube, and then flow out from the mouthpiece, when the smoking is stopped, the airflow sensor stops sending the electric signal to the circuit board, and the circuit board informs the battery to stop supplying the electric energy to the heating body 17.

[0043] In the design, the valve 12 is used to connect the atomizing assembly and the oil tank 11, the moving assembly 13 is a magnetic moving part arranged inside the oil tank 11, a spring 14 is arranged between the magnetic moving part and the inner wall of the oil tank 11, the magnetic moving part includes two magnetic poles arranged oppositely and having opposite polarities, one of the magnetic poles is close to the valve 12, and the other magnetic pole is close to the spring 14 (also referred to as a compression spring), the electromagnet 21 is arranged outside the oil tank 11, and specific description is as follows: the magnetic moving part includes an N pole and an S pole, the magnetic moving part is made of silica gel material, the magnetic moving part moves left and right along the bottom of the oil tank 11, the left side of the magnetic moving part is the N pole, and the right side of the magnetic moving part is the S pole; after the electromagnet 21 is powered on, the upper end of the electromagnet 21 is the S pole, and the lower end of the electromagnet 21 is the N pole; after the electromagnet 21 stops being powered on, the electromagnet 21 no longer has magnetism. In the initial state, the spring is in a compressed state, but the compression force is relatively small, the compression force enables the magnetic moving part to press the valve 12, ensures that the tobacco tar cannot flow out through the valve 12, and the magnetic moving part cannot be separated from the valve 12; the magnetic moving part is located on the left side, the left side of the magnetic moving part blocks the valve 12, at this time, the spring 14 cannot pull the magnetic moving part, and the tobacco tar in the oil tank 11 cannot enter the oil guide body 16 through the valve 12, thereby preventing the tobacco tar from flowing outwards.

[0044] The movement of the electromagnet 21 has the following three cases: in the initial state, the magnetic moving part blocks the valve 12; in the first case, after the electromagnet 21 is powered on in the positive direction, the upper end of the electromagnet 21 is the S pole, the N pole on the left side of the magnetic moving part is attracted by the electromagnet 21, the S pole on the right side of the magnetic moving part is subjected to upward repulsion, the magnetic moving part moves to the right, the valve 12 is opened, and the spring 14 is in a compressed state; when the N pole on the left side of the magnetic moving part moves to the position directly above the electromagnet 21, the movement stops, at this time, the attraction between the N pole on the left side of the magnetic moving part and the S pole at the upper end of the electromagnet 21 reaches the maximum.

[0045] In the second case, when the electromagnet 21 is not powered on, the magnetic moving part is pushed by the spring 14, and under the pushing of the spring 14, the magnetic moving part moves towards the valve 12, and finally the magnetic moving part blocks the valve 12; in this case, the electromagnet 21 does not need to be powered on, and the energy of the spring 14 is released after the spring 14 is compressed, the elastic potential energy is converted into kinetic energy, the magnetic moving part is pushed to the valve 12, and then the magnetic moving part stays at the valve 12, thereby achieving oil blocking, without the need for power on, and the electric energy can be saved; because the valve 12 needs to be blocked in normal state, the magnetic moving part cannot be powered on all the time to keep the valve 12 blocked, and the situation that the electromagnet 21 is powered on for a long time to heat can also be prevented.

[0046] The third case is as follows: after the electromagnet 21 passes a reverse direction current, at this time, the upper end of the electromagnet 21 is N-pole, the lower end of the electromagnet 21 is S-pole, the N-pole on the left side of the magnetic moving piece is repelled by the N-pole on the upper end of the electromagnet 21, the N-pole on the left side of the magnetic moving piece is subjected to an upward repelling force, the S-pole on the right side of the magnetic moving piece is attracted by the N-pole on the upper end of the electromagnet 21, the magnetic moving piece moves to the left, and in addition, the spring 14 is compressed, which also gives the magnetic moving piece a leftward pushing force, the two forces act on the magnetic moving piece to make the magnetic moving piece move to the left, the N-pole on the left side of the magnetic moving piece is subjected to an upward repelling force, which can reduce the frictional force in the movement process, facilitate the magnetic moving piece to move to the valve 12 easily, and then block the valve 12, which belongs to the case of forcibly closing the valve 12.

[0047] The above is the hardware structure part of the atomization device of the present design, and the following will introduce the key content of the present design.

[0048] The control system for locking oil and lubricating core of an atomization device comprises a main control module, an induction module (such as an air flow sensor) connected to the main control module, the induction module being used for detecting the change of air pressure in the process of suction and converting the action of suction into an electric signal to send to the main control module, an atomization assembly 15 connected to the main control module, the main control module controlling whether the atomization assembly 15 is powered to heat, a read-write unit connected to the main control module, and a chip provided with a storage module, the storage module being used for storing the time length of remaining lubricating core or the number of remaining lubricating core of a cartridge.

[0049] When the cartridge 1 is placed in the opening on the upper part of the main body, the cartridge 1 is connected with the main machine 2, the upper part of the main machine 2 is provided with a plug-in space, the plug-in space is provided for the cartridge 1 to be inserted, the plug-in space is provided with two elastic pins and a signal terminal, the two elastic pins and the signal terminal are both connected with a circuit board, the lower surface of the cartridge 1 is provided with two electrode columns and a signal butt joint column, the two electrode columns are respectively connected with the heating body 17, and the signal butt joint column is connected with the chip, after the cartridge 1 is inserted into the plug-in space, the two electrode columns are respectively butt jointed with the two elastic pins, and the signal butt joint column is connected with the signal terminal, the battery provides electric energy through the circuit board, the circuit board firstly controls the signal terminal to provide electric energy to the signal butt joint column on the lower surface of the cartridge 1 to charge the chip, after the chip is powered on, the read-write unit starts to read the data information of the chip through the signal terminal and the signal butt joint column, the read-write unit can also write data information in the storage module of the chip through the signal terminal and the signal butt joint column, and meanwhile, the elastic pins are connected with the electrode columns, so as to facilitate the battery to supply electric energy to the heating body 17 through the circuit board, the elastic pins and the electrode columns.

[0050] When the read-write unit detects that the remaining duration or the number of remaining wicks of the storage module is 0, the cartridge 1 is marked as a cartridge that has completed wicking. For the cartridge that has completed wicking, the host module informs the atomization assembly 15 to heat according to the electrical signal of the sensing module. When the read-write unit detects that the remaining duration or the number of remaining wicks of the storage module is greater than 0, the cartridge 1 is marked as a cartridge that has not been wick or a cartridge that has not completed wicking. For the cartridge that has not been wick or the cartridge that has not completed wicking, the host module informs the atomization assembly 15 not to heat.

[0051] In order to ensure that the read-write unit can accurately read the data of the storage module, the data protocol format and the check are specified. The storage module in the cartridge 1 has the ability to store a certain length of data. In order to ensure that the data read from the storage module is valid data, the application specifies a specific data protocol format and a check method. The data format is specified as 4 bytes, of which the first and second bytes are defined as "protocol header" for identifying the start and type of the data and the like; the third byte is "payload" M (M is an integer greater than 0, and its value represents the duration or number of times that the atomizer needs to be wick before the electronic atomization device works normally); and the fourth byte is "check bit", which can be generated by any suitable check method, such as parity check, CRC check, etc.

[0052] When the cartridge 1 establishes a connection with the host 2, the read-write unit of the host module in the host 2 starts to read the data in the storage module provided in the chip, and judges the read data according to the specified data format and check method. If the read data does not conform to the specified data format, for example, the protocol header is incorrect, the check is not passed, etc., it is determined that the cartridge 1 is a cartridge that has not been wick (also called a brand new cartridge). At this time, the host module initializes the payload M to a preset value M, and writes the complete data protocol into the storage chip of the atomizer according to the established data format, to provide basic data for subsequent wick control and state judgment.

[0053] If the read data conforms to the protocol, it is determined that the cartridge 1 is a cartridge that has not completed wicking. Then the host module directly analyzes the payload data of the third byte and records it as N, which is used for subsequent state judgment. If N is greater than 0, it indicates that the cartridge 1 has not completely completed the wicking process. At this time, the host 2 marks its own working state as "wicking state", and performs corresponding operation control according to the state. If N = 0, it indicates that the cartridge 1 has completely completed the wicking process, and the cartridge 1 is marked as a cartridge that has completed wicking.

[0054] Through the design of the system, whether the cartridge 1 has completed the process of wetting the wick can be detected. For the cartridge that has completed the process of wetting the wick, normal suction can be carried out. The main control module informs the atomization assembly 15 to heat according to the electric signal of the induction module, so that the tobacco tar is heated into smoke and flows out from the cigarette holder of the cartridge 1. For the cartridge that has not completed the process of wetting the wick, even if the suction through the cigarette holder continues, the main control module informs the atomization assembly 15 not to heat, so that normal suction cannot be carried out. This can effectively protect the cartridge and prevent the heating body 17 from dry burning and the oil guide cotton from burning.

[0055] The process of wetting the wick will be introduced below. The main control module is also connected to the electromagnet 21. The cartridge 1 is provided with a chip, an oil tank 11, a valve 12, an atomization assembly 15 and a magnetic moving piece. The magnetic moving piece includes a first magnetic pole and a second magnetic pole that are oppositely arranged and have opposite polarities. The first magnetic pole is close to the valve 12, and the second magnetic pole is away from the valve 12. A compression spring 14 is arranged between the second magnetic pole and the oil tank 11. When the induction module detects that the user performs a suction action, the induction module converts the suction action into an electric signal and sends it to the main control module. The main control module first determines whether the current working state is "wetting the wick state". The upper part of the oil tank 11 is provided with an oil injection hole. The oil injection hole is provided with a sealing plug. When the oil is injected for the first time, the sealing plug needs to be pulled out of the oil injection hole, the tobacco tar is injected, and then the sealing plug is plugged to prevent the tobacco tar from leaking out. During the process of wetting the wick, the valve is closed, which can prevent the tobacco tar from flowing out through the valve. Because when the oil is injected, the gas in the oil tank is compressed by the tobacco tar and will flow out along the valve. If too much tobacco tar is injected, it will cause the tobacco tar to flow out from the atomization assembly, because the amount of tobacco tar adsorbed by the atomization assembly is limited. When the amount of tobacco tar in the atomization assembly reaches a certain amount, if the oil tank is continuously pressurized, it will cause the tobacco tar to leak out. Therefore, when the oil is injected, the valve must be closed.

[0056] In the first case of suction, for the cartridge that has completed the process of wetting the wick, the main control module informs the atomization assembly 15 to heat according to the electric signal of the induction module, and the electromagnet 21 is electrified. The magnetic moving piece moves away from the valve 12 to open the valve 12, and the tobacco tar in the oil tank 11 enters the atomization assembly 15 through the valve 12.

[0057] The second case is that when the cartridge is not fully primed, the main control module informs the atomization assembly 15 not to heat, the read-write unit directly analyzes the payload data N in the chip, and the electromagnet 21 is powered. The magnetic moving part moves away from the valve 12 to open the valve 12, and the oil in the oil tank 11 enters the atomization assembly 15 through the valve 12. The read-write unit reduces the value of N in the storage module by one each time the valve 12 is opened until it is zero, and normal suction can be performed. For example, if the value of N is 3, the valve 12 needs to be opened 3 times, and the value of N is reduced by one each time the valve 12 is opened. The value of N is changed to 2, and the read-write unit writes the value 2 into the storage module. In this way, the remaining priming time information is always recorded in the chip in real time. Even if the cartridge is inserted and removed during the priming process, since the remaining time data is recorded in the storage module of the chip, when the cartridge is inserted again, the control system can continue to complete the remaining priming process from the breakpoint, without starting from the beginning, greatly improving the convenience and efficiency of use.

[0058] The third case is that when the cartridge is not primed, the main control module informs the atomization assembly 15 not to heat, and writes the number of times M that need to be primed into the storage module, and the electromagnet 21 is powered. The magnetic moving part moves away from the valve 12 to open the valve 12, and the oil in the oil tank 11 enters the atomization assembly 15 through the valve 12. The read-write unit reduces the value of M in the storage module by one each time the valve 12 is opened until it is zero, and normal suction can be performed. For example, if M is 10 times, the valve 12 needs to be opened 10 times for normal suction. Whether the priming action is interrupted or not, after the valve 12 is opened 3 times, it means that the priming has been performed 3 times, and 7 times of priming are still needed. The read-write unit writes the value 7 into the storage module in real time. In this way, the remaining priming time information is always recorded in the chip in real time. Even if the cartridge is inserted and removed during the priming process, since the remaining time data is recorded in the storage module of the chip, when the cartridge is inserted again, the control system can continue to complete the remaining priming process from the breakpoint, without starting from the beginning, greatly improving the convenience and efficiency of use.

[0059] The design is a method for locking oil and priming a cartridge, which includes the following steps.

[0060] a, provide an atomization device, the atomization device includes host computer 2 and smoke bullet 1, the host computer 2 is provided with battery, circuit board, circuit board connects battery, the smoke bullet 1 is provided with chip, oil storehouse 11, valve 12, atomization component 15 and movement component 13;Initial state, smoke bullet 1 and host computer 2 are separated, facilitate smoke bullet 1 and host computer 2 complete oil injection and detection work respectively, of course, smoke bullet 1 and host computer 2 can be loaded together, smoke bullet 1 and host computer 2 are assembled and constitute electronic cigarette, when the initial state, smoke bullet 1 is empty, there is no tobacco tar in the oil storehouse 11 of smoke bullet 1, after smoke bullet 1 and host computer 2 are docked, tobacco tar is injected into oil storehouse 11;Or tobacco tar is injected into oil storehouse 11 first, then smoke bullet 1 and host computer 2 are assembled, but valve 12 is closed, and tobacco tar cannot enter atomization component 15 through valve 12.

[0061] b, connect host computer 2 and smoke bullet 1, host computer 2 detects whether smoke bullet 1 is an unprimed smoke bullet or a primed smoke bullet, if it is an unprimed smoke bullet, the circuit board initializes the payload of the chip to M and writes the payload M into the chip, the design is explained by taking the number of times as an example, for example, M is 10 times, indicating that the smoke bullet needs to be primed 10 times, of course, the same principle can be explained by taking the time length as an example;If it is a primed smoke bullet, directly analyze the payload data N in the chip, and record N in the circuit board, for example, N is 7 times, indicating that the smoke bullet needs to be primed 7 times, N < M, if N = 0, mark the smoke bullet as a primed smoke bullet, if N ≠ 0, mark the smoke bullet as a smoke bullet that has not been primed completely;This is the process of identifying the smoke bullet, although the oil storehouse 11 in the smoke bullet has been injected with oil, but it is unknown whether the atomization component 15 is full of tobacco tar or whether it is completely wetted by tobacco tar. If it is the case that the smoke bullet and host computer 2 are docked, and then tobacco tar is injected into the oil storehouse 11, the human eye can directly judge that the priming has not been completed, but in the other case, the human eye cannot directly judge the priming condition, whether the priming is completed or not, etc. For example, tobacco tar is injected into the oil storehouse 11 first, whether the smoke bullet that has been injected with tobacco tar has been assembled with other host computers 2, whether the priming action of the smoke bullet is stopped after the tobacco tar is injected, or whether the smoke bullet and other host computers 2 are assembled for priming, but whether the number of times or the time length of priming meets the preset requirements, these problems must be objectively and accurately judged in order to execute the subsequent actions.

[0062] c. For the cartridge that has been fully primed, when suction is performed from the mouthpiece of the cartridge, the circuit board instructs the movement assembly 13 to open the valve 12, and the oil in the oil tank 11 flows to the atomization assembly 15 through the valve 12, and the circuit board instructs the atomization assembly 15 to start atomizing the oil, normal suction can be performed, and the user does not need to wait and can directly perform normal suction. For the cartridge that has not been fully primed and the cartridge that has not been primed, when suction is performed from the mouthpiece of the cartridge, the circuit board instructs the atomization assembly 15 not to atomize the oil. For such cartridges, the dry burning of the heating element 17 can be effectively prevented, the life of the atomization assembly 15 is protected, and step d is entered.

[0063] d. For the cartridge that has not been primed, the circuit board instructs the movement assembly 13 to open the valve 12, and simultaneously starts the timing / counting function. From the opening to the closing of the valve 12 once, a time length T is defined. The circuit board changes the payload data of the chip to M-1 and stores it in the chip until M=0, and then normal suction can be performed. For example, after a time length T, the valve 12 is opened and closed once, indicating that the cartridge has been primed once. The value corresponding to M-1 is 9, indicating that the cartridge needs to be primed 9 more times. In this way, the value of M decreases to 0. For the cartridge that has not been fully primed, the circuit board instructs the movement assembly 13 to open the valve 12, and simultaneously starts the timing / counting function. After a time length T, the circuit board changes the payload data of the chip to N-1 and stores it in the chip until N=0, and then normal suction can be performed. For example, after a time length T, the valve 12 is opened and closed once, indicating that the cartridge has been primed once. The value corresponding to N-1 is 6, indicating that the cartridge needs to be primed 6 more times. The valve 12 is repeatedly opened and closed until the value of N is 0. M and N are natural numbers, and M and N can be selected according to the actual number of priming times.

[0064] Through the above method, the cartridge that has been fully primed, the cartridge that has not been primed, and the cartridge that has not been fully primed can be distinguished. The circuit board performs different actions on the atomization assembly 15, accurately manages the working state of the electronic cartridge, ensures the stable operation of the equipment in various situations, and allows normal suction for the cartridge that has been fully primed. For the cartridge that has not been primed and the cartridge that has not been fully primed, normal suction cannot be performed. The circuit board instructs the movement assembly 13 to open the valve 12 to perform the priming action, so that the oil fully enters the atomization assembly 15, the dry burning of the heating element 17 can be effectively prevented, the remaining time length / number of times is recorded in real time during the priming process, and after the atomizer is inserted and removed in the middle, the priming can continue from the breakpoint without the need to start over. Especially for the cartridge that has not been fully primed, the convenience and efficiency of user use are improved, and the user experience is enhanced.

[0065] In step b, the host 2 detects the method of the cartridge is an unprimed cartridge or a primed cartridge as follows: after the chip is powered on, the circuit board starts reading the data information of the chip through the signal line, and the data format and verification method are pre-stored in the circuit board. If the read data information of the chip does not conform to the pre-stored data format and verification method, the cartridge is marked as an unprimed cartridge. If the read data information of the chip conforms to the pre-stored data format and verification method, the cartridge is marked as a primed cartridge. A specific data protocol format and verification method is adopted to ensure that the data read from the chip is valid data, improve the accuracy and reliability of data management, and provide a solid data basis for the judgment of the cartridge state and priming control.

[0066] If it is an unprimed cartridge, define M as the number of times of priming required, and indicate that the number of times of priming required is M, so as to perform normal suction. For example, M is 10 times, which indicates that the cartridge needs to be primed for 10 times, and the valve 12 needs to be opened for 10 times, so as to perform normal suction. M is pre-set according to the structure of the atomization assembly 15, the required amount of tobacco tar, the required time, and other factors. If it is a primed cartridge, define N as the number of times of priming required. If N = 0, it indicates that the number of times of priming required is zero, and the cartridge has been primed for 10 times, so it does not need to be primed any more and can directly perform normal suction. If N ≠ 0, it indicates that the number of times of priming required is N, so as to perform normal suction. The values of M and N need to be pre-written in the storage module of the cartridge according to a data rule, so as to facilitate quick reading and also prevent random modification of data, and ensure the authenticity and objectivity of data.

[0067] In step c, when suction is performed from the suction nozzle of the cartridge, the circuit board first detects whether the cartridge is an unprimed cartridge or a primed cartridge. For a cartridge that has been primed completely, normal suction can be performed. For a cartridge that has not been primed completely and an unprimed cartridge, the circuit board informs the atomization assembly 15 not to atomize tobacco tar, and at the same time, the circuit board informs the movement assembly 13 to periodically open and close the valve 12 until the number of times of priming is completed. Different measures need to be taken for different cartridges, and the host 2 needs to judge according to the data information of the chip to avoid artificial judgment. A specific data protocol format and verification method is adopted to ensure that the data read from the storage chip is valid data, improve the accuracy and reliability of data management, and improve the accuracy and reliability of data management.

[0068] In step d, from the opening to the closing of the valve 12, a time T is a core wetting, for the cartridge which has not been wetted, in the K-th wetting process, K is a natural number, if the cartridge is separated from the host 2, at this time the cartridge has been wetted K-1 times, the circuit board records that the cartridge has been wetted K-1 times, the circuit board changes the payload data of the chip to M-(K-1), and stores M-(K-1) in the chip, indicating that the cartridge still needs to be wetted M-(K-1) times to perform normal smoking. This real-time recording method can record the number of remaining wettings in the chip. When the cartridge is used, the host 2 directly reads the number of remaining wettings from the chip, and directly wets for several times, reducing the wetting time and improving the convenience and efficiency of user use, and enhancing the user experience.

[0069] In step d, from the opening to the closing of the valve 12, a time T is a core wetting, for the cartridge which has not been wetted, in the K-th wetting process, K is a natural number, if the cartridge is separated from the host 2, at this time the cartridge has been wetted K-1 times, the circuit board records that the cartridge has been wetted K-1 times, the circuit board changes the payload data of the chip to M-(K-1), and stores M-(K-1) in the chip, indicating that the cartridge still needs to be wetted M-(K-1) times to perform normal smoking. This real-time recording method can record the number of remaining wettings in the chip. When the cartridge is used, the host 2 directly reads the number of remaining wettings from the chip, and directly wets for several times, reducing the wetting time and improving the convenience and efficiency of user use, and enhancing the user experience.

[0070] The host 2 is also provided with a display screen. For the cartridge which has not been wetted, until M=0, the display screen starts to display a normal working state. For the cartridge which has not been wetted completely, until N=0, the display screen starts to display a normal working state, so that the user can directly see the wetting data and know the progress state, how long the cartridge can be smoked, and when the cartridge can be smoked, and increase the interest while the user is waiting.

[0071] The host 2 is provided with an electromagnet 21 connected to the circuit board. The moving assembly 13 is a magnetic moving part, which includes oppositely arranged first and second magnetic poles with opposite polarities. The first magnetic pole is close to the valve 12, and the second magnetic pole is away from the valve 12. A compression spring 14 is arranged between the second magnetic pole and the oil tank 11. When the electromagnet 21 is powered, the magnetic moving part moves away from the valve 12 to open the valve 12. When the electromagnet 21 is not powered, the compression spring 14 pushes the magnetic moving part to move close to the valve 12 and block the valve 12. From the opening of the valve 12 to the closing of the valve 12, it is a period. This point has been described in detail above. The oil tank 11 is designed to be transparent, so that the user can directly see the left and right movement of the magnetic moving part.

[0072] The above merely describes the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural changes made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
