The liquid is atomized. Please refer to Figure 11, the matching part 153 on the cartridge 10 is in contact with the detection component 25 when the cartridge 10 is installed on the battery device 20, and is separated from the detection component 25 when the cartridge 10 is removed from the battery device 20, the detection component 25 is connected to the controller 29, the detection component 25 is used to generate a separation signal when it is separated from the mating part 153, and the controller 29 is used to control the heating element 21 to work according to the separation signal and preset parameters to remove the residue attached to the heating element 21 things. Residues include, but are not limited to, aerosol-forming substrates, carbides generated at high temperatures.

In this embodiment, please refer to FIG. 8 to FIG. 12 , the detection assembly 25 includes a sensor seal 26, a first chamber 253, a second chamber 254, a first sensor 251 and a second sensor 252, the first chamber 253 and the second The chamber 254 is arranged on one side of the battery holder 23 and is close to the upper end of the battery holder 23. The sensor seal 26 is provided with a first part 261 and a second part 262 respectively corresponding to the first chamber 253 and the second chamber 254. The first sensor 251 is installed in the first part 261 of the sensor seal 26 and placed into the first cavity 253, the opening of the first cavity 253 communicates with the air inlet 152, and the second sensor 252 is installed in the second part 262 of the sensor seal 26 and Inserted into the second chamber 254 , when the pod 10 is installed on the battery device 20 , the matching portion 153 blocks the opening of the second chamber 254 .

Fig. 18 is a schematic cross-sectional view of the cartridge of the electronic cigarette in the second embodiment of the present invention. 19 is a schematic cross-sectional view of the battery device of the electronic cigarette in the second embodiment of the present invention. As shown in Figure 18 and Figure 19, the main difference between the electronic cigarette of this embodiment and the electronic cigarette of the previous embodiment is that in the cartridge 50 of this embodiment, the matching part 553 provided on the base 55 is not a sealing protrusion At the same time, the detection components on the battery device 60 of this embodiment are also different from those of the first embodiment.

In this embodiment, the detection component includes a state detection circuit (not shown in the figure), and the state detection circuit is used to detect the installation state of the cartridge 50. When the cartridge 50 is installed on the battery device 60, the state detection circuit and the matching part 553 When the cartridge 50 is removed from the battery device 60, the state detection circuit is released from the cooperation with the matching part 553 and is in a disconnected state. The separation signal generated when the upper is removed. In this embodiment, a switch element 653 is provided in the state detection circuit. When the cartridge 50 is installed on the battery device 60, the matching part 553 drives the switch element 653 to conduct the state detection circuit. 60 is removed from the mating portion 553 and resets, so that the state detection circuit is disconnected to generate a separation signal.

In actual implementation, the switch element 653 includes a thimble 651 and a switch button 652. The battery device 60 is provided with a thimble installation through hole on the installation side of the pod 50. The thimble 651 is penetrated in the thimble installation through hole, and the thimble 651 protrudes from the bracket seal. 62 and corresponds to the position of the matching part 553 on the pod 50, the thimble 651 is connected to an elastic element and can be automatically reset after the external force is removed. The position is corresponding, the switch button 652 is connected with an elastic element and can be automatically reset after the external force is removed. When the cartridge 50 is installed on the battery device 60, the matching part 553 presses the switch button 652 to the closed position through the thimble 651, and the cartridge 50 from When the battery device 60 is removed, the thimble 651 is reset under the action of the corresponding elastic element, and then the switch button 652 is reset to the disconnected position under the action of the corresponding elastic element. At this time, the state detection circuit is disconnected and a separation signal is generated. The matching part 553 that can push the thimble 651 can be a surface or a groove or a protrusion of the base 55 of the pod 50, as long as the thimble 651 can be pressed down with the movement of the pod 50, there is no limitation on the shape , in this embodiment, the side of the lower end surface of the base 55 opposite to the air inlet 152 is used as the matching portion 553 .

It can be understood that the structure of the switch element 653 in this embodiment is not limited thereto. For example, the switch element 653 is only a switch button, and the matching part 553 provided on the pod 50 is a push rod. When the pod 50 is installed , the push rod on the pod 50 can press the switch button to the closed position. When the pod 50 is removed from the battery device 60, the push rod leaves the switch button, and the switch button resets under the action of the corresponding elastic element to detect the disconnected state. circuit. Alternatively, the switch element 653 is only a switch button, the top of which protrudes from the outside of the bracket seal 62, and the matching part 553 provided on the pod 50 is a flat surface or a groove. When the pod 50 is installed , the pod 50 can directly press the switch button to the closed position. When the pod 50 is removed from the battery device 60, the pod 50 leaves the switch button, and the switch button resets under the action of the corresponding elastic element to disconnect the state detection circuit. .

In this embodiment, the battery device 60 is also provided with a third cavity 61 and a third sensor 66, the third cavity 61 is arranged on the battery holder 63, the third cavity 61 is connected with the mouthpiece of the electronic cigarette (please refer to the The setting of the first chamber 253) communicates, and the third sensor 66 is arranged in the third chamber 61, and the third sensor 66 is used to detect the airflow state in the third chamber 61. When the suction effect of the user, the third chamber 61 When negative pressure is generated inside, the third sensor 66 generates an airflow signal, and the controller is used to control the heating element to perform atomization according to the airflow signal. In this way, when the state detection circuit is turned on, the electronic cigarette confirms that the pod 50 is in the installed state, and at this time judges whether the user is taking a puff according to the airflow signal of the third sensor 66 . When the user sucks the electronic cigarette, the air in the third chamber 61 is sucked out along with the mouthpiece, the third chamber 61 is in a negative pressure state, and the airflow signal generated by the third sensor 66 is at a high level. When the smoke is in the suction state, the corresponding working parameters control the heating element to work, that is, control the heating element to perform normal atomization work. It should be understood that after detecting the separation signal that the cartridge 50 is removed from the battery device 60 , it indicates that the cartridge 50 has been removed. At this time, even if the airflow signal is detected to be at a high level, the heating element will not be controlled to work.

Through the electronic cigarette with the above structure, the heating element can be arranged on the battery device 60 to reduce the replacement cost of the cartridge 50. In addition, the battery device 60 is provided with a state detection circuit and a resettable switch element 653, which can be connected with the cartridge 50.

Device life.

In the first embodiment and the second embodiment, the matching part is in contact with the detection assembly when the cartridge is installed on the battery device, and is separated from the detection assembly when the cartridge is removed from the battery device. A separation signal is generated when separated from the mating part. It can be understood that, in other unshown embodiments, the matching part and the detection assembly can also adopt other cooperation methods, as long as the detection assembly generates a separation signal when the cartridge is removed from the battery device. For example, the matching part and the detection component may not be in contact all the time. Specifically, the detection component includes a light source and a light sensor. When the pod is installed on the battery device, the light beam generated by the light source is reflected by the matching part, so that the light sensor detects the light beam. When the pod is removed, the light beam cannot be reflected, so that the light sensor detects that the light beam disappears, and the light sensor generates a removal signal accordingly.

The electronic cigarette of the present invention includes a cartridge and a battery device, the cartridge and the battery device are detachably connected, the battery device is provided with a heating element, a detection component and a controller, and when the cartridge is removed from the battery device, the detection component generates a separation signal, The controller is used to control the heating element to work according to the separation signal to remove residues on the heating element. The invention can automatically remove the residue on the heating element when the cartridge is removed from the battery device, thereby improving the service life of the heating element and electronic components in the battery device.

The control method of the electronic cigarette in the above-mentioned embodiment will be described in detail below.

Fig. 20 is a schematic flowchart of a method for controlling an electronic cigarette in an exemplary embodiment of the present invention. As shown in Figure 20, the electronic cigarette control method of this embodiment includes but not limited to the following steps:

Step S1, detecting the separation signal generated when the pod is removed from the battery device, wherein the aerosol-forming substrate is stored in the pod, and the battery device is provided with a heating element, which is used to heat the gas in the pod when energized. Sol-forming matrix;

Step S2, when the separation signal is detected, the heating element is controlled to work to remove the residue on the heating element.

Among them, the structure between the pod and the battery device is a detachable connection. The aerosol-forming substrate is stored in the pod. The aerosol-forming substrate is, for example, liquid smoke, tobacco paste, shredded tobacco and other substances that can produce inhalable smoke. The battery device There is a heating element on it, and the heating element is used to heat the aerosol-forming matrix in the cartridge to form smoke when it is energized. When the cartridge is removed from the battery device, the liquid-absorbing element is separated from the heating element. There may be residues left during use, such as aerosol-forming matrix remaining on the heating element or other carbides formed after heating. In one embodiment, the aerosol-forming substrate is smoke liquid, and a corresponding liquid-absorbing element is provided on the cartridge to supply liquid smoke to the heating element. When the cartridge is installed on the battery device, the liquid-absorbing element is in contact with the heating element or Close to, so that the smoke liquid stored in the pod can be supplied to the heating element for atomization.

In one embodiment, corresponding to the above-mentioned first embodiment, when the first sensor and the second sensor are provided on the battery device, step S1 detects the separation signal generated when the cartridge is removed from the battery device, including:

Acquiring the first airflow signal of the first sensor and the second airflow signal of the second sensor, wherein the first sensor is arranged in the first chamber of the battery device, the second sensor is arranged in the second chamber of the battery device, and the second sensor is arranged in the second chamber of the battery device. One chamber communicates with the airflow channel of the electronic cigarette and is isolated from the second chamber, and the second chamber is in a closed state when the cartridge is installed on the battery device and is in an open state after the cartridge is removed from the battery device;

If the first airflow signal is at a low level and the second airflow signal is at a high level, a separation signal generated when the cartridge is removed from the battery device is detected.

Wherein, the first sensor is arranged in the first chamber on the battery device, the second sensor is arranged in the second chamber on the battery device, the first chamber communicates with the airflow channel of the electronic cigarette, and the first chamber and the second chamber communicate with each other. They are not connected but isolated from each other. The second cavity is in a closed state when the cartridge is installed on the battery device and is in an open state after the cartridge is removed from the battery device. When the pod is installed on the battery device, it is inserted into the opening of the second cavity and the opening is blocked. In this way, when the pod is removed from the battery device, the second cavity will generate negative pressure due to the extraction of the sealing part and cause airflow. Disturbance, the second airflow signal of the second sensor is a high-level signal. At the same time, since the user will not inhale when removing the cartridge, there will be no airflow in the airflow channel of the electronic cigarette, and there will be no airflow when the cartridge is pulled out. It will cause the air pressure in the first chamber to change, so the first airflow signal of the first sensor is a low-level signal. Therefore, when the first airflow signal is low-level and the second airflow signal is high-level, it can be considered smoke The pod is currently being removed from the battery device, the first airflow signal is low level and the second airflow signal is high level, which is equivalent to the separation signal that the pod is removed from the battery device.

When the separation signal is detected, the electronic cigarette controls the heating element to work to remove the residue on the heating element. In actual implementation, the electronic cigarette controls the heating element to work according to the preset parameters, thereby starting the self-cleaning mode to remove the residue on the heating element. Among them, the preset parameters include one of the preset working voltage, the preset temperature and the preset power, and the preset working time. The preset working voltage is greater than the working voltage when the electronic cigarette is in the smoking state. Equal to the current output voltage of the battery, the preset temperature is greater than the working temperature when the electronic cigarette is in the suction state, the working temperature is the atomization temperature when the heating element is working normally, and the preset power is greater than the working power when the electronic cigarette is in the suction state , the working power is also the atomization power of the heating element when it is working normally. By adopting a higher working voltage, working temperature or working power, the attached residue can be quickly consumed in a short period of time. The preset working time is a relatively long time. A short duration, for example, 1 second. Of course, in actual implementation, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in the smoking state, and the residue on the heating element can also be removed, the difference is only in the length of time for elimination.

When the battery device is provided with a first sensor and a second sensor respectively located in the first chamber and the second chamber, the electronic cigarette control method may further include the following steps:

If both the first airflow signal and the second airflow signal are both at low level or at high level, the heating element is controlled not to work.

Wherein, if both the first airflow signal and the second airflow signal are at low level, it means that the electronic cigarette is in an idle state and the heating element does not work. When the electronic cigarette is inhaled without a pod installed, there will be airflow passing through both the first chamber and the second chamber, and the first airflow signal and the second airflow signal are both at high level. If it is a child at this time If the electronic cigarette is obtained and drawn against the electronic cigarette, controlling the operation of the heating element will cause burns. Therefore, when the first airflow signal and the second airflow signal are both at high level, the heating element does not work.

When the battery device is provided with a first sensor and a second sensor respectively located in the first chamber and the second chamber, the electronic cigarette control method may further include the following steps:

If the first airflow signal is at a high level and the second airflow signal is at a low level, the heating element is controlled to work according to the corresponding operating parameters when the electronic cigarette is in a puffing state.

Among them, when the user smokes the electronic cigarette, there is airflow passing through the airflow channel of the electronic cigarette, and the airflow signal generated by the first sensor is at a high level. At this time, combined with the airflow signal of the second sensor, it is judged whether the cartridge is currently installed. When the user smokes the electronic cigarette, the second sensor will not detect the airflow change only when the second chamber is in a closed state. It can be seen that if the second airflow signal is a low-level signal at this time, it indicates that the second chamber is in a closed state , The pod is installed on the electronic cigarette. Therefore, when the first airflow signal is at a high level and the second airflow signal is at a low level, it indicates that the pod has been installed and the user is smoking. At this time, the electronic cigarette is controlled according to the corresponding working parameters when the electronic cigarette is in the smoking state. The heating element works, that is, the heating element is controlled to perform normal atomization work.

After controlling the heating element to work according to the corresponding working parameters when the electronic cigarette is in the smoking state, the electronic cigarette control method may further include the following steps:

If the resistance value of the heating element rises to the preset resistance value for less than the preset duration, the heating element is controlled to stop working;

If the duration for which the resistance value of the heating element rises to the preset resistance value is greater than or equal to the preset duration, the output power of the heating element is controlled so that the resistance value of the heating element remains at the preset resistance value.

Among them, the preset resistance value is the atomization resistance value when the electronic cigarette is atomized, which is the normal working resistance value. Usually, the electronic cigarette will set an atomization temperature when it leaves the factory, and the atomization temperature corresponds to the temperature of a heating element. Resistance value, when the electronic cigarette is working, the battery device outputs voltage to the heating element to make the heating element work and monitor the resistance value of the heating element in real time. When the resistance value of the heating element reaches the resistance value corresponding to the preset atomization temperature, it passes Control the output power so that the resistance value of the heating element is stable at this resistance value, which is the aforementioned atomization resistance value. Of course, the atomization resistance value can also be calculated according to the actual atomization temperature or power set by the user. During the heating process of the electronic cigarette, if the resistance value of the heating element rises to the preset resistance value for less than the preset duration, it means that the heating element heats up too fast due to dry burning. In order to protect the cartridge, stop heating at this time ; If the time for the resistance of the heating element to rise to the preset resistance value is greater than or equal to the predetermined time, it means that the heating element is working normally. At this time, by controlling the output power of the heating element, the resistance of the heating element is stabilized at the preset resistance. Stable resistance means that the deviation of the resistance value of the heating element relative to the preset resistance value is within a small range.

In another embodiment, corresponding to the above-mentioned second embodiment, when a state detection circuit is provided on the battery device, step S1 detects the separation signal generated when the cartridge is removed from the battery device, including:

Obtain the on-off signal of the state detection circuit, wherein the state detection circuit is used to detect the installation state of the pod, the state detection circuit is set on the battery device, and the state detection circuit is in the conduction state when the pod is installed on the battery device, the state The detection circuit is disconnected when the pod is separated from the battery device;

If the on-off signal is an off signal, a separation signal generated when the cartridge is removed from the battery device is detected.

Wherein, the state detection circuit is arranged on the battery device to detect the installation state of the pod. In this embodiment, the state detection circuit is provided with a switch element for turning on and off the state detection circuit, and the switch element includes an elastic element And the switch button connected to the elastic element, when the cartridge is installed on the battery device, the cartridge presses the switch button on the switch element by pressing the thimble provided on the battery device or the push rod provided on the cartridge, The elastic element in the switch element is in a deformed state, and the switch element is closed to conduct the state detection circuit. At this time, the on-off signal of the state detection circuit is a conduction signal, that is, the state detection circuit changes from an off state to a conduction state, then The electronic cigarette recognizes that the installation signal of the pod is detected or that the pod is in the installed state; when the pod is pulled out from the battery device, the pod no longer presses the thimble or ejector rod, and the external force of the thimble or ejector rod on the switch button Removed, the deformation of the elastic element in the switch element recovers, the switch button is reset, and the state detection circuit is disconnected. At this time, the on-off signal of the state detection circuit is an off signal, that is, the state detection circuit changes from the on state to the off state. Then the electronic cigarette detects the separation signal of the cartridge.

When the separation signal is detected, the electronic cigarette controls the heating element to work to remove the residue on the heating element. In actual implementation, the electronic cigarette controls the heating element to work according to the preset parameters, so as to remove the residue on the heating element. Wherein, the preset parameters include one of the preset working voltage, the preset temperature and the preset power, and the preset duration. The preset working voltage is greater than the working voltage when the electronic cigarette is in the smoking state. The current output voltage of the battery, the preset temperature is greater than the working temperature when the electronic cigarette is in the suction state, the working temperature is the atomization temperature when the heating element is working normally, and the preset power is greater than the working power when the electronic cigarette is in the suction state, The working power is also the atomization power of the heating element when it is working normally. By adopting a higher working voltage, working temperature or working power, the attached residue can be quickly consumed in a shorter period of time. For example, the preset working time is a longer A short duration, for example, 1 second. Of course, in actual implementation, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in the smoking state, and the residue on the heating element can also be removed.

Wherein, when the state detection circuit and the third sensor are provided on the battery device, the electronic cigarette control method may further include the following steps:

When the pod is in the installed state, the third airflow signal of the third sensor is obtained, wherein the third sensor is arranged in a third chamber on the battery device, and the third chamber is communicated with the airflow channel of the electronic cigarette;

If the third airflow signal is at a high level, the heating element is controlled to work according to the corresponding working parameters when the electronic cigarette is in a puffing state.

When the on-off signal of the state detection circuit on the battery device is an on-off signal, the electronic cigarette confirms that the pod is in the installed state, and at this time judges whether the user is taking a puff according to the airflow signal of the third sensor. When the user smokes the electronic cigarette, there is airflow passing through the airflow channel of the electronic cigarette, and the airflow signal generated by the third sensor is at a high level. At this time, the electronic cigarette controls the heating element according to the corresponding working parameters when the electronic cigarette is in the suction state Carry out work, that is, control the heating element to perform normal atomization work. It should be understood that after detecting the separation signal that the pod is removed from the battery device, it indicates that the pod is removed and is in an uninstalled state. At this time, even if the third airflow signal is detected to be at a high level, the heating element will not be controlled to work.

After controlling the heating element to work according to the corresponding working parameters when the electronic cigarette is in the smoking state, the electronic cigarette control method may further include the following steps:

If the resistance value of the heating element rises to the preset resistance value for less than the preset duration, the heating element is controlled to stop working;

If the duration for which the resistance of the heating element rises to the preset resistance is greater than or equal to the preset duration, the output power of the heating element is controlled so that the resistance of the heating element remains at the preset resistance.

Among them, the preset resistance value is the atomization resistance value when the electronic cigarette is atomized, which is the normal working resistance value. Usually, the electronic cigarette will set an atomization temperature when it leaves the factory, and the atomization temperature corresponds to the temperature of a heating element. Resistance value, when the electronic cigarette is working, the battery device outputs voltage to the heating element to make the heating element work and monitor the resistance value of the heating element in real time. When the resistance value of the heating element reaches the resistance value corresponding to the preset atomization temperature, it passes Control the output power so that the resistance value of the heating element is stable at this resistance value, which is the aforementioned atomization resistance value. Of course, the atomization resistance value can also be calculated according to the actual atomization temperature or power set by the user. During the heating process of the electronic cigarette, if the resistance value of the heating element rises to the preset resistance value for less than the preset duration, it means that the heating element heats up too fast due to dry burning. In order to protect the cartridge, stop heating at this time ; If the time for the resistance of the heating element to rise to the preset resistance value is greater than or equal to the predetermined time, it means that the heating element is working normally. At this time, by controlling the output power of the heating element, the resistance of the heating element is stabilized at the preset resistance. Stable resistance means that the deviation of the resistance value of the heating element relative to the preset resistance value is within a small range.

In one embodiment, the electronic cigarette control method may further include the following steps:

Control the heating element to work according to the received preset operation signal to remove the residue on the heating element;

During the working process of the heating element, obtain the resistance change rate of the heating element;

If the rate of change of the resistance value is less than the preset rate of change, the heating element is controlled to stop working;

If the resistance value change rate is greater than or equal to the preset change rate, the heating element is controlled to work to remove the residue on the heating element.

Among them, a self-cleaning manual button is also provided at the bottom of the electronic cigarette. When the manual button is pressed, a preset operation signal for controlling the heating element to work is generated, and the heating element starts to heat for self-cleaning. The preset change rate refers to the resistance change rate when the heating element works to remove the residue under the condition that the pod is not installed. When the heating element works with the preset parameters to remove the residue, the preset change rate is It refers to the resistance value change rate when the heating element works with preset parameters under the condition that no pod is installed. During the self-cleaning process, if the pod is still inserted into the e-cigarette, the heating element will have more aerosol-forming substrates attached to it, making the resistance value change rate less than the preset change rate. If self-cleaning continues at this time, it will If the pod is damaged, in order to ensure that the pod is in good condition, control the heating element to stop working and stop self-cleaning. On the contrary, if the resistance value change rate is greater than or equal to the preset change rate, it is considered that the heating element is not in contact with the aerosol in the pod. , residue cleaning can be carried out, and at this time continue to control the work of the heating element.

In the electronic cigarette control method of the present invention, an aerosol-forming matrix is stored in the cartridge of the electronic cigarette, and a heating element is provided on the battery device, and the heating element is used to heat the aerosol-forming matrix in the cartridge when it is powered on. When the separation signal of the pod is removed from the battery device, the heating element is controlled to work to remove the residue on the heating element. In this way, the present invention can automatically remove residues on the heating element for self-cleaning when the pod is removed from the battery device, thereby improving the service life of the heating element.
