[0040] like Figure 1 As shown, this embodiment provides an electronic atomization device 10, which can be used for atomization of liquid substrates. The electronic atomization device 10 includes an atomizer 11 and a battery assembly 12. Among them, one end of the atomizer 11 is detachably connected to the battery assembly 12; when the atomizer 11 needs to be replaced, the atomizer 11 can be removed from the battery assembly 12, and the new atomizer 11 is connected to the battery assembly 12 to achieve the reuse of the battery assembly 12. The atomizer 11 can be used in different fields, such as medical atomization, electronic atomization, etc. The atomizer 11 is used to store the substrate to be atomized and atomize the substrate to be atomized to generate an aerosol. In this embodiment, the atomizer 11 is used to atomize the substrate to be atomized and generate an aerosol for the user to inhale; of course, in other embodiments, the atomizer 11 can also be used in hairspray equipment to atomize hairspray for hair styling; or in medical equipment for treating upper and lower respiratory system diseases to atomize medical drugs. The battery assembly 12 is used to supply power to the atomizer 11 so that the atomizer 11 can atomize the liquid matrix to form an aerosol.

[0041] The atomizer 11 includes a first shell, a mounting seat and an atomizing core. A liquid storage cavity, a mounting cavity and an air outlet channel are formed in the first shell. The liquid storage cavity is used to store the liquid matrix to be atomized. The liquid storage cavity can be made of metal such as aluminum and stainless steel, or can be made of plastic. It only needs to be able to store the liquid matrix to be atomized and not react with it to cause it to deteriorate. The shape and size of the liquid storage cavity are not limited and can be designed as needed.

[0042] The first shell forms a mounting cavity on the side of the liquid storage cavity close to the battery assembly 12. The air outlet channel and the liquid storage cavity are arranged side by side on the same side of the mounting cavity, and the air outlet channel is connected to the outside atmosphere. The mounting seat is arranged on the side of the mounting cavity close to the battery assembly 12, and the atomizer core is installed on the mounting seat, and cooperates with the mounting seat to form an atomizer cavity. The atomizer cavity is connected to the air outlet channel, that is, the atomizer cavity, the air outlet channel and the outside atmosphere are connected to each other. Among them, one end of the mounting seat close to the battery assembly 12 is exposed, and the mounting seat is detachably connected to the first shell.

[0043] The atomizer core is used to atomize the matrix to be atomized in the liquid storage chamber into an aerosol. The atomizer core includes a heating element and a porous element. The liquid in the liquid storage chamber enters the porous element, and the porous element uses capillary force to guide the liquid matrix to be atomized to the heating element, and the heating element heats and atomizes it to form an aerosol. The heating element can be a heating wire, a heating net, a heating film, a heating circuit, etc., which can be selected according to needs. The porous element can be a porous ceramic or a cotton core.

[0044] The battery assembly 12 includes a second shell, a control board, a magnetic element and a battery. The second shell has a receiving cavity, and the battery is arranged in the receiving cavity. The battery is used to power the atomizer core. A magnetic encoding chip and a main control chip are arranged on the control board. The magnetic element is connected to the second shell of the battery assembly 12, and the encoding chip is connected to the main control chip. The encoding chip generates magnetic induction encoding information according to the changing magnetic field signal generated by the magnetic element under the pressing operation, and the main control chip controls the locking and unlocking related states of the electronic atomization device according to the magnetic induction encoding information.

[0045] In one embodiment, Figure 2 and Figure 3 As shown, an electronic atomization device is provided, including a magnetic element 110, a magnetic encoding chip 120, a main control chip (not shown in the figure) and a shell 210, the magnetic element 110 is connected to the shell 210, and the magnetic element 110 generates a changing magnetic field signal under a pressing operation; the magnetic encoding chip 120 is arranged in the shell 210, within the magnetic field generated by the magnetic element 110, and has no contact with the magnetic element 110, the magnetic encoding chip 120 senses the changing magnetic field signal of the magnetic element 110, and outputs magnetic induction coding information to the main control chip based on the changing magnetic field signal; the main control chip is communicatively connected with the magnetic encoding chip 120, receives the magnetic induction coding information, and controls the locking and unlocking related states of the electronic atomization device according to the magnetic induction coding information.

[0046] Among them, the magnetic element 110 can be a magnet, and the shell 210 can be a metal shell. The magnetic element 110 can be arranged on the inner surface or the outer surface of the shell 210. Taking the case where the magnetic element 110 is arranged on the inner surface of the shell 210 as an example, when the user presses the shell 210, the magnetic element 110 generates a magnetic field change according to the deformation of the shell 210. In one embodiment, the electronic atomization device also includes a control board 220, and the magnetic encoding chip 120 and the main control chip are both arranged on the control board 220. The control board 220 can specifically be a PCB (Printed Circuit Board) board. The magnetic encoding chip 120 obtains the changing magnetic field signal of the magnetic element 110 to generate magnetic induction coding information, and sends the magnetic induction coding information to the main control chip. The main control chip controls the related states of the locking and unlocking of the electronic atomization device according to the magnetic induction coding information, for example, when the magnetic induction coding information matches the pre-stored data, the electronic atomization device is unlocked. By installing a magnetic element 110 on the inner surface of the shell 210 to sense the user's pressing operation, and also installing the magnetic encoding chip 120 on the control board 220 where the main control chip is located, there is no need to change the original structure of the electronic atomization device, and the product appearance of the electronic atomization device will not be damaged.

[0047] The electronic atomization device obtains the coded information generated by the changing magnetic field signal generated by the magnetic element 110 under the pressing operation, and controls the locking and unlocking related states of the electronic atomization device according to the magnetic induction coded information. The user can generate coded information to control the locking and unlocking related states of the electronic atomization device by pressing the operation to generate a magnetic field change, which is not easy to be unlocked by children and can well prevent accidental startup, and has high reliability in preventing false startup.

[0048] In one embodiment, the magnetic element 110 is disposed on the inner surface of the housing 210, and a pressing mark area 212 is disposed on the outer surface of the housing 210 at a position corresponding to the magnetic element 110. The user can press multiple pressing positions around the boundary of the pressing mark area 212, or press at different forces or durations at a fixed position in the middle of the pressing mark area 212. In this embodiment, when the magnetic element 110 is disposed on the inner surface of the housing 210, a pressing mark area 212 is also disposed on the outer surface of the housing 210 to facilitate the user to perform the pressing operation.

[0049] In another embodiment, the magnetic element 110 is disposed inside the housing 210 and exposed on the outer surface of the housing 210. Specifically, the magnetic element 110 can be disposed inside the housing 210 of the electronic atomization device, and a through hole can be opened in the housing 210 to expose the magnetic element 110 on the outer surface of the housing 210. The user can directly press the magnetic element 110 to change the magnetic field between the magnetic element 110 and the magnetic encoding chip 120.

[0050] Specifically, the number of the magnetic element 110 and the magnetic encoding chip 120 can be one or more, and the number of the magnetic element 110 and the magnetic encoding chip 120 can also be inconsistent. The magnetic element 110 can be directly attached to the housing 210 of the electronic atomization device; the magnetic element 110 can also be installed on a fixed structure and fixed to the housing 210 of the electronic atomization device through the fixed structure.

[0051] In one embodiment, Figure 3 and Figure 4 As shown, the electronic atomization device further includes a bracket 130, and the magnetic element 110 is fixed to the shell 210 through the bracket 130. Taking the case where the magnetic element 110 is fixed to the inner surface of the shell 210 through the bracket 130 as an example, when the user presses the shell 210 of the electronic atomization device, the deformation of the shell 210 drives the magnetic element 110 to deform through the bracket 130, so that the magnetic field between the magnetic element 110 and the magnetic encoding chip 120 also changes accordingly. The magnetic encoding chip 120 is installed on the control board 220 at a position corresponding to the magnetic element 110, and does not contact the corresponding magnetic element 110, so as to detect the change in the magnetic field of the magnetic element 110.

[0052] The positional relationship between the magnetic element 110 and the magnetic encoding chip 120 is not unique. In one embodiment, the orthographic projection of the magnetic encoding chip 120 on the housing 210 covers the orthographic projection of the magnetic element 110 on the housing 210. The orthographic projection of the magnetic encoding chip 120 on the housing 210 may cover the orthographic projection of one or more magnetic elements 110 on the housing 210. The positional relationship between the magnetic element 110 and the magnetic encoding chip 120 can be understood as that when the circumscribed circle of the magnetic element 110 is projected onto the plane where the magnetic encoding chip 120 is located, it is in an inner tangent or contained relationship with the circumscribed circle of the magnetic encoding chip 120 to ensure that the magnetic field change of the magnetic element 110 can be detected by the magnetic encoding chip 120.

[0053] In one embodiment, the number of magnetic elements 110 is more than two, the number of magnetic encoding chips 120 is at least one, and the positive projection of the magnetic encoding chip 120 on the shell 210 covers the positive projection of at least one magnetic element 110 on the shell 210. For each magnetic encoding chip 120, one or more magnetic elements 110 can be set correspondingly, and magnetic induction encoding information is generated by detecting the changing magnetic field signal of the corresponding magnetic element 110, so as to accurately identify the user's pressing operation. Further, in one embodiment, the area of ​​the magnetic encoding chip 120 projected on the shell 210 is greater than or equal to the area of ​​the user pressing the shell. For example, a pressing identification area 212 is set on the outer surface of the shell 210 to indicate that the user performs a pressing action in the pressing identification area 212. The area of ​​the magnetic encoding chip 120 projected on the shell 210 covers the pressing identification area 212 to further ensure that the user's action of pressing the shell 210 can be accurately detected.

[0054] The distance between the magnetic element 110 and the magnetic encoding chip 120 is not unique and can be designed according to actual needs. In one embodiment, the distance between the magnetic element 110 and the magnetic encoding chip 120 is greater than or equal to 0.4 mm and less than or equal to 2 mm, so as to avoid the distance between the magnetic element 110 and the magnetic encoding chip 120 being too large to affect the detection of magnetic field changes, and to avoid the distance between the magnetic element 110 and the magnetic encoding chip 120 being too small to limit the magnetic element 110 to follow the deformation of the shell to produce magnetic field changes.

[0055] After determining the positions of the magnetic element 110 and the magnetic encoding chip 120, the correspondence between different changing magnetic field signals and magnetic induction coding information can be saved in the magnetic encoding chip 120 in advance according to the actual situation. The magnetic induction coding information may include numbers, letters, etc. After the magnetic encoding chip 120 detects the changing magnetic field signal of the magnetic element 110 when the user presses the housing 210, the magnetic encoding chip 120 obtains the corresponding magnetic induction coding information according to the saved corresponding relationship, and realizes the conversion of the magnetic signal into a digital signal. The magnetic encoding chip 120 determines the corresponding magnetic induction coding information according to the changing magnetic field signal during different pressing actions of the user, and sends the obtained magnetic induction coding information to the main control chip.

[0056] It can be understood that the specific method in which the main control chip controls the locking and unlocking related states of the electronic atomization device according to the magnetic induction coding information is not unique. In one embodiment, the pressing operation is to press the shell 210, and the magnetic induction coding information is generated by pressing different positions of the shell 210 and pressing in different ways. Depending on the pressing position, pressing method, etc. when the user presses the shell 210, the magnetic field of the magnetic element 110 will produce changes in different positions or angles. Specifically, the magnetic encoding chip 120 can generate corresponding magnetic induction coding information according to different pressing positions on the shell 210; or it can generate corresponding magnetic induction coding information according to different pressing methods at the same pressing position on the shell 210. In addition, the magnetic encoding chip 120 can also generate corresponding magnetic induction coding information by comprehensively analyzing different pressing positions on the shell 210 and the pressing methods at each pressing position.

[0057] The magnitude of the magnetic field varies with the pressing position. Similarly, a pressing mark area 212 is set on the outer surface of the shell 210 of the electronic atomization device at a position corresponding to the magnetic element 110 (which can be called the magnetic element coverage area) to guide the user to perform a pressing operation. The user can press multiple pressing positions around the boundary of the pressing mark area 212, for example, in a clockwise or counterclockwise manner, or in combination with multiple pressing positions, such as Figure 4 As shown, when the user presses positions ①, ②, ③, and ④, the magnetic element 110 generates corresponding magnetic field changes according to the user's pressing actions at different positions, and the magnetic encoding chip 120 determines the actual pressing position based on the detected changing magnetic field signal, and then determines the magnetic induction coding information corresponding to the pressing position.

[0058] Furthermore, the type of pressing method is not unique, and may specifically include at least one of long press, short press, number of presses within a predetermined time, and pressing force. Correspondingly, the user may also press with different forces or durations at a fixed position in the middle of the pressing mark area 212. Correspondingly, the magnetic element 110 generates a magnetic field change according to the user's pressing action at the fixed position, and the magnetic encoding chip 120 analyzes the user's pressing force, pressing time or number of presses according to the magnetic field change. For example, the magnetic encoding chip 120 determines that the user's pressing time exceeds the set threshold and determines it as a long press, if it does not exceed the set threshold, it is determined as a short press; for another example, the magnetic encoding chip 120 can also analyze the user's pressing force, or the number of presses of the user within a predetermined time. The magnetic encoding chip 120 can determine the corresponding magnetic induction coding information according to the identified changing magnetic field signal when the user performs a pressing action by pre-saving the magnetic induction coding information corresponding to the user's long press, short press, pressing force, and number of presses.

[0059] In one embodiment, the main control chip controls the electronic atomization device to unlock when the electronic atomization device is not started and the magnetic induction coding information is the same as the first pre-stored coding information. Specifically, the first pre-stored coding information, as the saved password data, may be composed of one or more coding information. When the electronic atomization device is in an unstarted state, if the main control chip receives the magnetic induction coding information sent by the magnetic coding chip 120, the received magnetic induction coding information is compared with the saved first pre-stored coding information. If the two are consistent, the electronic atomization device is unlocked; conversely, if the received magnetic induction coding information is inconsistent with the first pre-stored coding information, the electronic atomization device is not unlocked.

[0060] Furthermore, in one embodiment, when the magnetic induction coding information is the same as the second pre-stored coding information, the main control chip controls the electronic atomization device to enter a password setting state and obtains the magnetic induction coding information in the password setting state; if a confirmation instruction is received, the magnetic induction coding information obtained in the password setting state is saved as the first pre-stored coding information.

[0061] Among them, the second pre-stored coding information is used as the judgment data of whether the electronic atomization device enters the password setting state. When the magnetic induction coding information sent by the magnetic coding chip 120 is the same as the second pre-stored coding information, the electronic atomization device enters the password setting state, and the received magnetic induction coding information in the password setting state is saved as the first pre-stored coding information. Specifically, after the electronic atomization device is successfully started, when the user needs to set or modify the password of the electronic atomization device, a specific pressing action is performed on the shell 210 of the electronic atomization device so that the magnetic induction coding information sent by the magnetic coding chip 120 is the same as the second pre-stored coding information, and the electronic atomization device enters the password setting state. At this time, the user sets the password combination by pressing the operation and inputs the password data to the main control chip. For example, when a password needs to be set, the user can use a specific pressing method, such as long pressing, short pressing, pressing a set number of times at a fixed time, etc. to make the electronic atomization device enter the password setting state, which is convenient for user operation. Furthermore, after the main control chip determines that a confirmation instruction has been received based on the magnetic induction coding information sent by the magnetic coding chip, the magnetic induction coding information obtained in the password setting state is saved as password data and the password setting state is exited. The user only needs to press to unlock according to the set password sequence next time.

[0062] It is understandable that when the electronic atomization device is started for the first time, the user does not need to use a specific pressing action to make the electronic atomization device enter the password setting state, and can directly set the password by pressing, and the main control chip will save the received password data.

[0063] In addition, in one embodiment, the main control chip can also control the interactive device to provide status prompts according to the state of the electronic atomization device. Specifically, the interactive device can be a display screen, an indicator light, a speaker, etc. The main control chip can control the interactive device to provide status prompts according to the state of the electronic atomization device so that the user can know. Taking the status prompt through the indicator light as an example, the main control chip can output a password setting prompt message through the indicator light after the electronic atomization device enters the password setting state, informing the user that the password setting program has been started and a new password can be set. After saving the new password, the main control chip can also output a password setting success prompt message through the indicator light to inform the user that the new password has been set successfully. When the user starts the electronic atomization device next time, the main control chip determines that the magnetic induction coding information sent by the magnetic coding chip 120 is consistent with the saved password data, unlocks the electronic atomization device, and outputs a password input correct prompt message through the indicator light, informing the user that the password is correct and the electronic atomization device is successfully unlocked.

[0064] In one embodiment, Figure 5 As shown, a control method of an electronic atomization device is also provided, the method comprising:

[0065] Step S100: Obtain magnetic induction coding information. The magnetic induction coding information is coding information generated by a changing magnetic field signal generated by a magnetic element connected to the shell of the electronic atomization device under a pressing operation. The pressing operation is to press the shell, and the magnetic induction coding information is generated by pressing different positions of the shell and different pressing methods. The size of the magnetic field is different for different pressing positions. Furthermore, the pressing method includes at least one of: long press, short press, number of presses within a predetermined time, and pressing force.

[0066] Step S200: controlling the locking and unlocking related states of the electronic atomization device according to the magnetic induction coding information.

[0067] In one embodiment, step S200 includes: if the electronic atomization device is not started, and the magnetic induction coding information is the same as the first pre-stored coding information, controlling the electronic atomization device to unlock.

[0068] In one embodiment, step S200 also includes: if the magnetic induction coding information is the same as the second pre-stored coding information, controlling the electronic atomization device to enter a password setting state; obtaining the magnetic induction coding information in the password setting state; if a confirmation instruction is received, saving the magnetic induction coding information obtained in the password setting state as the first pre-stored coding information.

[0069] It should be noted that the specific implementation of the control method of the electronic atomization device has been explained in detail in the above-mentioned electronic atomization device, which will not be repeated here.

[0070] In order to better understand the control method of the electronic atomization device and the electronic atomization device, the electronic atomization device is taken as an example for detailed explanation below.

[0071] The current child lock and accidental start-up prevention methods of electronic atomizer devices are all achieved through physical buttons, touch, pressure-sensing buttons, fingerprints, etc., which require destroying the product appearance, reduce the product appearance effect, are difficult to assemble, are costly, and are easily triggered by mistake, and cannot prevent accidental start-up. In addition, the current accidental start-up prevention method has fixed unlocking and locking modes, is simple to operate, and is easy for children to learn and unlock.

[0072] Based on this, the present application provides a child lock and an anti-accidental start solution that forms a code by pressing to judge the change in the magnetic field, which is specifically implemented through a magnetic coding chip + magnetic element. By pressing the metal shell of the electronic atomization device, the magnetic element is deformed and the corresponding magnetic field changes occur. By judging the change in the magnetic field at different positions or angles, the corresponding magnetic induction coding information is formed, and the lock and unlock password is formed through the magnetic induction coding information.

[0073] Specifically, Figure 2-4 As shown, when the user presses the magnetic element coverage area of ​​the shell 210, the shell 210 will produce micron-level deformation, and at the same time drive the magnetic element 110 to produce micron-level deformation. The deformation causes the magnetic field between the magnetic element 110 and the magnetic encoding chip 120 to change. The magnetic encoding chip 120 detects the position or angle of the magnetic field change, and generates different magnetic induction coding information according to the magnetic field changes at different positions. The magnetic encoding chip 120 sends the detected magnetic induction coding information to the main control chip for identification and judgment, and makes corresponding control.

[0074] Depending on the pressing position, pressing area, pressing force, etc. when the user presses the shell 210, the magnetic field of the magnetic element 110 will produce changes in different positions or angles. The correspondence between different magnetic field changes and magnetic induction coding information can be saved in the magnetic encoding chip 120 in advance. After the magnetic encoding chip 120 detects the change magnetic field signal generated by the magnetic element 110 when the user presses the shell, the corresponding magnetic induction coding information is obtained according to the saved correspondence, and the magnetic signal is converted into a digital signal. The electronic atomization device itself does not need to make any structural changes, and only needs to electrically connect a magnetic encoding chip 120 to the PCB board. The magnetic encoding chip 120 can sense the micro-deformation caused by the pressing area of ​​the shell pressed by the user's finger. Among them, the area where the user presses the shell is less than or equal to the area projected on the shell by the magnetic encoding chip 120. There can be multiple magnetic elements 110, and correspondingly, multiple magnetic encoding chips 120 are also required, but the number may not be corresponding. It is only required that the magnetic element 110 does not contact the corresponding magnetic encoding chip 120, and when the circumscribed circle of the magnetic element 110 is projected onto the plane where the magnetic encoding chip 120 is located, it is internally tangent to or contained in the circumscribed circle of the magnetic encoding chip 120. Furthermore, the dimension between the magnetic element 110 and the magnetic encoding chip 120 is greater than 0.4 mm and less than 2.0 mm, and the housing is in full contact with the magnetic element 110.

[0075] In addition, users can also enter the password setting state through a specific pressing method (long press, short press, number of presses within a fixed time, etc.), and set the password combination by pressing different positions.
