Detailed implementation mode

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0032] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data may be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0033] Referring to Figure 1 , an atomization device is provided in an embodiment of the present application, including: a first bin for storing an atomization matrix to be atomized; a second bin for storing the atomization matrix, and the second bin is configured to supplement the atomization medium to the first bin; an atomization component disposed in the first bin for atomizing the atomization matrix; a main control chip for obtaining the working duration of the atomization component and the communication duration between the first bin and the second bin, generating a first signal group according to the working duration and a first preset duration, and generating a second signal group according to the communication duration and a second preset duration; a switching component disposed between the first bin and the second bin for switching the state of the first bin and the second bin to be connected according to the first signal group, or switching the state of the first bin and the second bin to be disconnected according to the second signal group;

[0034] Wherein, when the working duration is greater than or equal to the first preset duration, the main control chip generates the first signal group; when the communication duration between the first bin and the second bin is greater than or equal to the second preset duration, the main control chip generates the second signal group.

[0035] In this embodiment, the state of the first bin and the second bin is switched to be connected or disconnected according to the working duration of the atomization component to ensure that the stock of the atomization matrix in the first bin is appropriate, avoiding the dry burning phenomenon caused by too little stock of the atomization matrix in the first bin of the atomization device or the leakage of the atomization matrix caused by too much stock.

[0036] In some embodiments, the main control chip 10 may be a microcontroller unit (MCU) or other types of chips. The atomizing device may be an electronic cigarette or other types of atomizing devices; the second chamber of the atomizing device may be in the form of a bottle, a can, etc.; the atomizing matrix may be e-liquid or other types of atomizing matrices.

[0037] In some embodiments, when the stock of the atomizing matrix in the first chamber is less than or equal to the first preset stock, it is determined that the remaining amount of the atomizing matrix in the first chamber of the atomizing device is too small; when the stock of the atomizing matrix in the first chamber is less than or equal to the second preset stock and greater than the first preset stock, it is determined that the stock of the atomizing matrix in the first chamber is moderate, so that the internal pressure of the atomizing device is moderate and the atomizing matrix leakage of the atomizing device is avoided; when the stock of the atomizing matrix in the first chamber is greater than the second preset stock, it is determined that the stock of the atomizing matrix in the first chamber is too large, so that the internal pressure of the atomizing device is too large, causing the atomizing matrix leakage of the atomizing device.

[0038] For example, the first preset stock is 0.2 ml, the second preset stock is 2 ml, the first preset duration is 2 minutes, the second preset duration is 1 second, the original stock of the atomizing matrix in the first chamber of the atomizing device is 2 ml. When the working duration is 2 minutes, the stock of the atomizing matrix in the first chamber of the atomizing device becomes 0.2 ml, indicating that the remaining amount of the atomizing matrix in the first chamber of the atomizing device is too small. At this time, the main control chip 10 generates a first signal group, and then the switching component K1 switches the states of the first chamber and the second chamber to be connected according to the first signal group. The atomizing matrix in the second chamber enters the first chamber. After 1 second, the stock of the atomizing matrix in the first chamber becomes 2 ml, and it is determined that the stock of the atomizing matrix in the first chamber is moderate. The main control chip 10 generates a second signal group, and then the switching component K1 switches the states of the first chamber and the second chamber to be separated according to the second signal group. At the same time, the working duration of the atomizing component 60 is cleared and the timing starts again.

[0039] In some embodiments, when the working duration of the atomizing component 60 is less than the first preset duration, the main control chip 10 generates a second signal group, and the switching component K1 makes the states of the first chamber and the second chamber separated according to the second signal group.

[0040] In some embodiments, the switching component K1 includes a driving module 20 and a valve member 30. The driving module 20 drives the valve member 30 to have a relative displacement according to the first signal group or the second signal group.

[0041] In the embodiments of the present application, the working duration of the atomization component is obtained by the main control chip 10. When the working duration is greater than or equal to the first preset duration, it indicates that the remaining amount of the atomization matrix in the first chamber of the atomization device is too small. The main control chip 10 sends a first signal group to the driving module 20. Then, when the driving module 20 receives the first signal group, it drives the valve member 30 to have a relative displacement until it is in the first position, so that the first chamber is communicated with the second chamber, and the atomization matrix in the second chamber flows into the first chamber. After the second preset duration, it is determined that the stock of the atomization matrix in the first chamber is appropriate. The main control chip 10 sends a second signal group to the driving module 20. When the driving module 20 receives the second signal group, it drives the valve member 30 to have a relative displacement until it is in the second position (i.e., the valve member 30 is closed), so that the first chamber is disconnected from the second chamber. During this process, the stock of the atomization matrix in the first chamber is kept appropriate, and the leakage of the atomization matrix caused by too much stock of the atomization matrix in the first chamber of the atomization device is avoided.

[0042] In some embodiments, when the valve member 30 is open, the first chamber of the atomization device is communicated with the second chamber, and the atomization matrix in the second chamber can enter the first chamber; when the valve member 30 is closed, the first chamber of the atomization device is disconnected from the second chamber, and the second chamber is separated from the first chamber; after the valve member 3 has been closed, the working duration of the atomization component 60 is cleared and the timing starts again. Among them, the working duration of the atomization component 60 is negatively correlated with the stock of the atomization matrix in the first chamber; the second preset duration is positively correlated with the stock of the atomization matrix in the first chamber;

[0043] For example, the first preset stock is 0.2 ml, the second preset stock is 2 ml, the first preset duration is 2 minutes, the second preset duration is 1 second, and the original stock of the atomization matrix in the first chamber of the atomization device is 2 ml. When the working duration is 2 minutes, the stock of the atomization matrix in the first chamber of the atomization device becomes 0.2 ml, indicating that the remaining amount of the atomization matrix in the first chamber of the atomization device is too small. At this time, the main control chip 10 sends a first signal group to the driving module 20. Then, when the driving module 20 receives the first signal group, it drives the valve member 30 to open, so that the first chamber is communicated with the second chamber, and the atomization matrix in the second chamber enters the first chamber. After 1 second, the stock of the atomization matrix in the first chamber becomes 2 ml. It is determined that the stock of the atomization matrix in the first chamber is appropriate. The main control chip 10 sends a second signal group to the driving module 20. Then, when the driving module 20 receives the second signal group, it drives the valve member 30 to close, so that the first chamber is disconnected from the second chamber. At the same time, the working duration of the atomization component is cleared and the timing starts again.

[0044] In some embodiments, the driving module 20 includes: a motor 22 connected to the valve member 30 for driving the valve member 30 to undergo relative displacement; wherein, the motor 22 is driven in response to the first signal group, causing the valve member 30 to be in the first position, and the states of the first chamber and the second chamber are in communication; the motor 22 is driven in response to the second signal group, causing the valve member 30 to be in the second position, and the states of the first chamber and the second chamber are partitioned.

[0045] In the embodiments of the present application, when the working duration of the main control chip 10 is greater than or equal to the first preset duration, the main control chip 10 sends the first signal group to the driving module 20, and then the motor 22 is driven in response to the first signal group, causing the valve member 30 to be in the first position, and the states of the first chamber and the second chamber are in communication. The atomization matrix in the second chamber enters the first chamber. After the second preset duration, the main control chip 10 sends the second signal group to the driving module 20, and the motor 22 is driven in response to the second signal group, causing the valve member 30 to be in the second position, and the states of the first chamber and the second chamber are partitioned, and the atomization matrix in the second chamber stops entering the first chamber.

[0046] In some embodiments, the driving module 20 further includes: a driving chip 21, and the driving chip 21 is used to control the operation of the motor 22 according to the first signal group or the second signal group.

[0047] In the embodiments of the present application, when the working duration of the main control chip 10 is greater than or equal to the first preset duration, the main control chip 10 sends the first signal group to the driving chip 21. Then, when the driving chip 21 obtains the first signal group, the motor 22 is in the first working state. Then, when the motor 22 is in the first working state, the motor 22 drives the valve member 30 to open, causing the first chamber and the second chamber to be in communication, and the atomization matrix in the second chamber enters the first chamber. After the second preset duration, the main control chip 10 sends the second signal group to the driving chip 21. When the driving chip 21 obtains the second signal group, the motor 22 is in the second working state. When the motor 22 is in the second working state, the motor 22 drives the valve member 30 to close, causing the first chamber and the second chamber to be disconnected.

[0048] In some embodiments, referring to Figure 2, the driving module 20 includes a driving chip 21 and a motor 22; the main control chip 10 is electrically connected to the driving chip 21, and the main control chip 10 is configured to send a first signal group to the driving chip 21 when the working duration is greater than or equal to a first preset duration, and send a second signal group to the driving chip 21 after a second preset duration; the driving chip 21 is electrically connected to the motor 22, and the driving chip 21 is configured to make the motor 22 in a first working state when the first signal group is obtained, and make the motor 22 in a second working state when the second signal group is obtained. For example, the motor 22 is connected to the valve member 30, and when the motor 22 is in the first working state, the valve member 30 is driven to open; when the motor 22 is in the second working state, the valve member 30 is driven to close.

[0049] In some embodiments, the operating voltage range of the driving chip 21 is from 2.7 volts to 15 volts. The wide voltage range meets the low-voltage working requirements of the atomizing device. A 3.7-volt lithium battery can be used to supply power to the driving chip 21, and the driving chip 21 has protection functions such as under-voltage, over-current, and over-heat; the motor 22 can be a stepper motor or other types of motors; precise control of the opening and closing process of the valve member 30 can be achieved through the stepper motor.
