The control circuit board is also used to calculate the working time of the electric liquid pump according to the liquid consumption, the working power of the electric liquid pump and the liquid viscosity when the liquid consumption is higher than or equal to a first preset threshold value, so as to control the electric liquid pump to operate within the working time, so that the liquid conduction volume of the electric liquid pump is greater than or equal to the liquid consumption.

[0021] Optionally, in some embodiments of the present application, the control component also includes an alarm and a liquid level sensor for real-time monitoring of the liquid level in the liquid storage chamber, and the control circuit board is also electrically connected to the alarm and the liquid level sensor, respectively.

[0022] In addition, the embodiment of the present application also provides a control method of an electronic atomization device, which is applied to the above-mentioned electronic atomization device and includes the following steps:

[0023] The viscosity of the liquid in the liquid storage chamber is detected by the viscometer, and the working time of the atomization component is monitored in real time by the timer;

It can be seen that this technical solution can effectively improve the existing electronic atomizer devices, some of which use an electric liquid pump structure to pump the liquid in the liquid storage cavity into the liquid storage cotton, which easily causes excessive liquid in the liquid storage cavity to flow into the liquid storage cotton, resulting in oil leakage, affecting the user's experience.

[0042] In one embodiment, Figures 1 to 3As shown, an embodiment of the present application provides an electronic atomization device 1, which may specifically include a housing assembly 100, a liquid outlet pipeline 200 with an electric liquid pump 210, a liquid return pipeline 300, an atomization assembly 400, and a control assembly 500. Among them, the housing assembly 100 is mainly built with an air flow channel 11, a liquid storage cotton 12, and a liquid storage chamber 13. The liquid storage cotton 12 is arranged around the air inlet end of the air flow channel 11, and the surrounding wall of the liquid storage chamber 13 is respectively provided with a liquid outlet (not shown) and a liquid return port (not shown). One end of the liquid outlet pipeline 200 is connected to the liquid outlet, and the other end of the liquid outlet pipeline 200 is in liquid communication with the liquid storage cotton 12. One end of the liquid return pipeline 300 is connected to the liquid return port, and the other end of the liquid return pipeline 300 is in liquid communication with the liquid storage cotton 12, so that when the liquid in the liquid storage cotton 12 is greater than a preset threshold, the excess liquid is recovered to the liquid storage chamber 13. The atomizer assembly 400 is mainly arranged at the air inlet end of the air flow channel 11 and is in liquid communication with the liquid storage cotton 12, and is used to heat and atomize the liquid diverted from the liquid storage cotton 12 to form an aerosol. The control assembly 500 mainly includes a control circuit board (not shown in the figure) and a timer (not shown) for calculating the working time of the atomizer assembly 400. The control circuit board is electrically connected to the timer, the atomizer assembly 400 and the electric liquid pump 210 respectively. The control circuit board is used to calculate the liquid consumption of the liquid storage cotton 12 according to the working power of the atomizer assembly 400 and the working time of the atomizer assembly 400, and when the above-mentioned liquid consumption is higher than or equal to the first preset threshold value, the working time of the electric liquid pump 210 is calculated according to the liquid consumption and the working power of the electric liquid pump 210, so as to control the electric liquid pump 210 to work within the working time, so that the liquid diversion amount of the electric liquid pump 210 is greater than or equal to the above-mentioned liquid consumption.

[0043] It is understandable that the electronic atomization device 1 of the embodiment of the present application can be specifically used to store a specific liquid (specifically, it can be an atomization liquid such as tobacco oil) through the liquid storage chamber 13 and the liquid storage cotton 12, and during use, the stored specific liquid is diverted to the atomization component 400 through the liquid diversion of the liquid storage cotton 12, so that it is converted into an aerosol through the atomization component 400, and then sprayed outward through the air flow channel 11 for the user to inhale. The above-mentioned liquid storage cotton 12 is generally specially treated organic cotton, which has good liquid absorption and liquid conductivity, and can effectively absorb the liquid in the liquid storage chamber 13 and ensure the atomization effect. In addition, materials such as bamboo charcoal cotton can also be used as a substitute to enhance the suction taste of the electronic atomizer and reduce odors. The other end of the above-mentioned liquid outlet pipeline 200 is in liquid communication with the liquid storage cotton 12, which specifically means that the other end of the liquid outlet pipeline 200 is provided with a corresponding liquid outlet, and the liquid storage cotton 12 at least partially covers the liquid outlet, so that the liquid flowing out of the liquid outlet pipeline 200 through the liquid outlet can directly flow into the liquid storage cotton 12. The other end of the above-mentioned liquid return pipeline 300 is in liquid communication with the liquid storage cotton 12, which specifically means that the other end of the liquid return pipeline 300 is provided with a corresponding liquid inlet, and the liquid storage cotton 12 at least partially covers the liquid inlet, so that when the liquid in the liquid storage cotton 12 is greater than a preset threshold value (the preset threshold value is generally the maximum liquid storage volume of the liquid storage cotton 12), the excess liquid in the liquid storage cotton 12 can flow into the liquid return pipeline 300 through the liquid inlet, and then the liquid return pipeline 300 recovers it to the liquid storage chamber 13. The above-mentioned atomizing assembly 400 is mainly installed at the air inlet end of the air flow channel 11 and is in liquid communication with the liquid storage cotton 12. Specifically, the air inlet end of the air flow channel 11 is provided with a liquid guide port, and the liquid storage cotton 12 on the side of the air flow channel 11 can abut the atomizing assembly 400 through the liquid guide port, so that when there is liquid in the liquid storage cotton 12, the liquid can flow from the liquid storage cotton 12 to the atomizing assembly 400 through the liquid guide port. The above-mentioned control circuit board generally also includes a microphone (not shown) that controls the start and stop of the atomizing assembly 400 by sensing the air flow changes generated when the user sucks the electronic atomizing device 1. Therefore, the above-mentioned timer calculating the working time of the atomizing assembly 400 can be specifically that when the microphone starts the atomizing assembly 400 to perform atomization, the timer is started synchronously to perform timing work, and when the microphone closes the atomizing assembly 400, the timing work of the timer is synchronously paused.Generally speaking, the timer calculates the working time of the atomization component 400 by cumulative timing, that is, each time the electric liquid pump 210 stops working, that is, after completing the current liquid guiding work, the timer is reset synchronously and a new round of timing operation begins. At this time, each time the microphone starts the atomization component 400 to perform atomization work, the timer is started synchronously to perform timing work, and when the microphone turns off the atomization component 400, the timing work of the timer is paused synchronously, and the current liquid consumption of the liquid storage cotton 12 is calculated according to the working power of the atomization component 400 and the current timing duration of the timer to determine whether the current liquid consumption is higher than or equal to the first preset threshold value, and then determine whether it is necessary to start the electric liquid pump 210 to perform the corresponding liquid guiding work. The first preset threshold mentioned above can be adaptively adjusted according to the actual use requirements of the user of the electronic atomization device 1 to meet the different liquid replenishment requirements of different users for the liquid storage cotton 12.

[0044] In addition, since the liquid outlet pipeline 200 of the embodiment of the present application is provided with an electric liquid pump 210 for pumping liquid, the liquid outlet of the liquid storage chamber 13 can be opened and set at any position on the peripheral wall of the liquid storage chamber 13, which will not affect the liquid discharge effect of the liquid storage chamber 13. In addition, the electric liquid pump 210 mentioned above can be set to a single working gear or a plurality of different working gears. Under each working gear, the electric liquid pump 210 has a different working power and, correspondingly, has a different liquid conduction rate, that is, the current liquid conduction rate of the electric liquid pump 210 can be known according to the working power of the electric liquid pump 210. In this way, the working time of the electric liquid pump 210 can be calculated according to the liquid consumption and the working power of the electric liquid pump 210. In addition, the control circuit board mentioned above generally also includes a gear switch (not shown) for controlling the atomization component 400 to switch between different working states, that is, when the gear switch is switched to different gears, the atomization component 400 has different working powers, and then when the user inhales the electronic atomization device 1, the atomization component 400 has different atomization effects to meet the different inhalation needs of the user.

[0045] In this way, the electronic atomization device 1 provided in the embodiment of the present application, through the above-mentioned structural setting, has a new liquid return pipeline 300 between the liquid storage cotton 12 and the liquid storage chamber 13, so that when the liquid in the liquid storage cotton 12 is greater than a preset threshold, the excess liquid is recovered into the liquid storage chamber 13. That is, when too much liquid in the liquid storage chamber 13 flows into the liquid storage cotton 12, the excess liquid is actively recovered into the liquid storage chamber 13 through the liquid return pipeline 300, thereby avoiding related oil leakage problems, thereby greatly improving the user experience. At the same time, a timer for calculating the working time of the atomizer assembly 400 is added to the control assembly 500, so that the control circuit board of the control assembly 500 can calculate the liquid consumption of the liquid storage cotton 12 according to the working power of the atomizer assembly 400 and the working time of the atomizer assembly 400, and when the liquid consumption is higher than or equal to the first preset threshold, the working time of the electric liquid pump 210 is calculated according to the liquid consumption and the working power of the electric liquid pump 210, so as to control the electric liquid pump 210 to work within the working time, so that the liquid conduction amount of the electric liquid pump 210 is greater than or equal to the liquid consumption. In this way, the problem of core sticking caused by excessive consumption of liquid in the liquid storage cotton 12 and failure to obtain timely oil conduction replenishment during the use of the electronic atomizer device 1 can be effectively avoided.

[0046] In some examples, such as Figure 1 and Figure 2As shown, the liquid storage cotton 12 includes a first side surface (not shown in the figure) and a second side surface (not shown in the figure), and the first side surface and the second side surface are arranged opposite to each other in the extension direction of the air flow channel 11. The other end of the liquid outlet pipeline 200 is in liquid communication with the liquid storage cotton 12 via the first side surface, and the other end of the liquid return pipeline 300 is in liquid communication with the liquid storage cotton 12 via the second side surface. Thus, through the above-mentioned structural setting, the position on the liquid storage cotton 12 that is in liquid communication with the return liquid pipeline 300 can be in the extension direction of the air flow channel 11, away from the position on the liquid storage cotton 12 that is in liquid communication with the outlet liquid pipeline 200, so that the liquid from the outlet liquid pipeline 200 can be better ensured to reach the position on the liquid storage cotton 12 that is in liquid communication with the return liquid pipeline 300 only after the entire liquid storage cotton 12 is filled, thereby ensuring that only when the liquid in the liquid storage cotton 12 is greater than the preset threshold value (i.e., the maximum liquid storage volume of the liquid storage cotton 12), the excess liquid in the liquid storage cotton 12 will be recovered into the liquid storage chamber 13 through the return liquid pipeline 300. Furthermore, the second side surface is closer to the air flow outlet of the air flow channel 11 than the first side surface in the extension direction of the air flow channel 11. In this way, through the above-mentioned structural setting, when the user uses the electronic atomization device 1 for inhalation, the second side surface will be located above the first side surface, and then affected by gravity, which can further ensure that only after the liquid coming out of the liquid outlet pipeline 200 fills the entire liquid storage cotton 12, the liquid in the liquid storage cotton 12 will come to the position on the liquid storage cotton 12 that is liquid-connected with the return liquid pipeline 300, thereby ensuring that only when the liquid in the liquid storage cotton 12 is greater than the preset threshold value (that is, the maximum liquid storage capacity of the liquid storage cotton 12), the excess liquid in the liquid storage cotton 12 will be recovered into the liquid storage chamber 13 through the return liquid pipeline 300.

[0047] In some examples, such as Figure 1 and Figure 2 As shown, the liquid return port and the liquid outlet port are spaced apart in the extension direction of the airflow channel 11, and the liquid return port is closer to the airflow outlet of the airflow channel 11 than the liquid outlet port in the extension direction of the airflow channel 11. In this way, when the user uses the electronic atomization device 1 for inhalation, the position of the liquid return port will be higher than the position of the liquid outlet port, so as to ensure the liquid reflux effect of the liquid return pipeline 300 under the influence of gravity.

[0048] It can be understood that the specific shapes of the liquid return port and the liquid outlet mentioned in this example are not limited, including but not limited to a round port structure or a square port structure.

[0049] In some examples, such as Figure 1 and Figure 2As shown, the liquid return pipe 300 is extended in a direction perpendicular to the extension direction of the air flow channel 11, and the peripheral wall of the liquid return pipe 300 abuts the second side surface, so that the liquid inlet of the liquid return pipe 300 is at least partially immersed in the liquid storage cotton 12. In this way, through the above-mentioned structural arrangement, when the liquid in the liquid storage cotton 12 is greater than the preset threshold value (i.e., the maximum liquid storage volume of the liquid storage cotton 12), due to the abutment and squeezing of the second side surface of the liquid storage cotton 12 by the liquid return pipe, the excess liquid in the liquid storage cotton 12 is effectively recovered to the liquid storage cavity 13 through the liquid return pipe 300.

[0050] In some examples, such as Figures 1 to 3 As shown, the housing assembly 100 includes a first housing 110 and a base 120. The base 120 is installed at one end of the first housing 110 and is surrounded by the first housing 110 to form a first installation cavity 14. The airflow channel 11 and the liquid storage cotton 12 are respectively installed in the first installation cavity 14. In this way, by setting the first housing 110 and the base 120, the installation positions of the airflow channel 11 and the liquid storage cotton 12 can be reasonably arranged, and the airflow channel 11 and the liquid storage cotton 12 can be protected by the first installation cavity 14. Further, the housing assembly 100 also includes a second housing 130 having a liquid storage cavity 13, and the second housing 130 is fastened to the first housing 110. In this way, the liquid storage cavity 13 formed as a whole by the independent second housing 130 can maximize the liquid storage volume of the liquid storage cavity 13.

[0051] It can be understood that the second housing 130 in this example is extended along the extension direction of the air flow channel 11 to increase the liquid storage volume of the liquid storage chamber 13 as much as possible.

[0052] In some examples, such as Figures 1 to 3 As shown, at least one liquid guide port (not shown) is provided on the peripheral side wall of the air inlet end of the air flow channel 11, and the atomizer assembly 400 blocks all liquid guide ports so that the atomizer assembly 400 is in liquid communication with the liquid storage cotton 12. In this way, through the above-mentioned structural arrangement, it can be ensured that the atomizer assembly 400 is in better liquid communication with the liquid storage cotton 12. Further, two liquid guide ports are provided on the peripheral side wall of the air inlet end of the air flow channel 11, and the two liquid guide ports are arranged opposite to each other along the radial direction of the air flow channel 11. In this way, through the above-mentioned structural arrangement, it can be ensured that the liquid in the liquid storage cotton 12 penetrates more evenly into the entire atomizer assembly 400 to enhance the atomization effect of the atomizer assembly 400. Furthermore, the atomizer assembly 400 includes liquid guide cotton and a heating element, the liquid guide cotton blocks all liquid guide ports, and the heating element is mounted on the liquid guide cotton. Thus, through the above-mentioned structural setting, the liquid in the liquid-conducting cotton can be converted into aerosol and sprayed out through the heating work of the heating element on the liquid-conducting cotton, so as to be inhaled by the user.

[0053] It is understandable that the liquid-conducting cotton in this example can be made of the same material as the liquid-storing cotton 12 to ensure that it can effectively absorb the liquid in the liquid-storing cotton 12 and ensure the atomization effect. The number of liquid-conducting ports in this example can be arbitrarily increased or decreased according to actual needs, including but not limited to the two mentioned above. The shape of the liquid-conducting port in this example can be specifically rectangular, circular or other shapes. The heating element in this example can specifically be a heating sheet or a heating wire.

[0054] In some examples, such as Figures 1 to 3 As shown, the electronic atomization device 1 also includes a power supply component 600, which is electrically connected to the atomization component 400 and the electric liquid pump 210 respectively. In this way, through the above-mentioned structural setting, when the power supply component 600 performs power supply work, on the one hand, the power supply component 600 can power the electric liquid pump 210, so that the liquid in the liquid storage cotton 12 can be sucked into the liquid storage cotton 12 through the liquid outlet pipeline 200. On the other hand, the power supply component 600 can power the heating element of the atomization component 400, so that the heating element of the atomization component 400 heats the liquid guide cotton under the power supply of the power supply component 600, so as to convert the liquid in the liquid guide cotton into an aerosol spray for the user to inhale.

[0055] It can be understood that the power supply component 600 in this example may specifically include a control mainboard, a control switch, a battery and a charging interface, wherein the control mainboard and the power supply component 600 are installed as a whole in the shell component 100, wherein the control switch and the charging interface are respectively exposed on the surface of the shell component 100 to facilitate corresponding switch control and charging operations.

[0056] In some examples, such as Figure 1 and Figure 3 As shown, one end of the second housing 130 is fastened to the peripheral side of the first housing 110 to form an inverted L-shaped groove. The housing assembly 100 also includes a third housing 140, which surrounds an inverted L-shaped groove to form a second installation cavity 15 for installing the power supply assembly 600. In this way, through the above-mentioned structural setting, a second installation cavity 15 independent of the first installation cavity 14 and the liquid storage cavity 13 can be better formed to better independently install the power supply assembly 600, ensure that the power supply assembly 600 is away from the influence of the liquid in these chambers, and improve the service life of the power supply assembly 600.

[0057] It is understandable that the electric liquid pump 210 mentioned above can also be installed in the second installation cavity 15 in this example. The inverted L-shaped groove in this example refers to the gap formed by the part of the second shell 130 and the part of the first shell 110, and the third shell 140 surrounds the inverted L-shaped groove, which means that the third shell 140 surrounds the missing part of the gap to match the part of the second shell 130 and the part of the first shell 110 to form a complete cubic second installation cavity 15.

[0058] In some examples, such as Figure 1 and Figure 3 As shown, the third housing 140 is detachably fastened to the edge of the inverted L-shaped groove. Thus, through the above-mentioned structural setting, the third housing 140 can be removed at any time according to actual installation and maintenance needs, so as to open the second installation cavity 15 and facilitate the installation, maintenance and replacement of the power supply component 600 (generally specifically refers to the battery).

[0059] It can be understood that the detachable fastening connection in this example includes but is not limited to the snap structure 16 , that is, the third shell 140 and the edge of the inverted L-shaped groove body can be detachably fastened by the snap structure 16 .

[0060] In some examples, such as Figure 2 As shown, the control component 500 also includes a viscometer for detecting the liquid viscosity of the liquid in the liquid storage chamber 13, and the control circuit board is also electrically connected to the viscometer. The control circuit board is also used to calculate the working time of the electric liquid pump 210 according to the liquid consumption, the working power of the electric liquid pump 210 and the liquid viscosity when the liquid consumption is higher than or equal to the first preset threshold value, so as to control the electric liquid pump 210 to work within the working time, so that the liquid conduction amount of the electric liquid pump 210 is greater than or equal to the liquid consumption. It can be understood that in order to meet the suction needs of users with different tastes, liquids of different flavors can be stored in the liquid storage chamber 13, and for liquids of different flavors, the corresponding viscosities will have more or less differences. For the electric liquid pump 210, this difference will affect its liquid conduction rate. Even if the electric liquid pump 210 works at the same working power, the liquid conduction rate will have some changes due to the different viscosities of the liquid in the liquid storage chamber 13. In this way, the viscometer newly introduced through the above structure can fully consider the impact of the viscosity of the liquid in the liquid storage chamber 13 on the liquid conduction rate of the electric liquid pump 210, and further ensure the calculation accuracy of the working time of the electric liquid pump 210, so as to further ensure that the liquid conduction volume of the electric liquid pump 210 is greater than or equal to the liquid consumption.

[0061] In some examples, such as Figure 2As shown, the control component 500 also includes an alarm and a liquid volume sensor for real-time monitoring of the liquid volume in the liquid storage chamber 13. The control circuit board is also electrically connected to the alarm and the liquid volume sensor respectively. The control circuit board is also used to control the alarm to alarm when the liquid volume is lower than or equal to the second preset threshold. In this way, through the above-mentioned structural setting, the user can timely perform corresponding liquid replenishment operations on the liquid storage chamber 13 when the liquid volume in the liquid storage chamber 13 is low.

[0062] It is understandable that the alarm in this example can be a light alarm, a voice alarm, or even a combination of the two, so as to promptly remind the user to perform the corresponding refilling operation on the liquid storage chamber 13 in a timely manner in the form of voice and light. In addition, the second preset threshold in this example can be adaptively adjusted according to the actual use needs of the user to meet the different refilling reminder needs of different users.

[0063] In one embodiment, Figure 4 As shown, the embodiment of the present application also provides a control method for an electronic atomization device, which can be specifically applied to the electronic atomization device of the above embodiment, and mainly includes the following steps:

[0064] Step S110: Detect the liquid viscosity of the liquid in the liquid storage chamber by using a viscometer, and monitor the working time of the atomization component in real time by using a timer.

[0065] Step S120: Calculate the liquid consumption of the liquid storage cotton according to the working power of the atomizer assembly and the working time of the atomizer assembly, and determine whether the liquid consumption is higher than or equal to a first preset threshold.

[0066] Step S130: If the liquid consumption is higher than or equal to the first preset threshold, the working time of the electric liquid pump is calculated according to the liquid consumption and the working power of the electric liquid pump, and the electric liquid pump is controlled to work within the working time so that the liquid conduction volume of the electric liquid pump is greater than or equal to the liquid consumption.

[0067] It can be understood that, based on the above description, in the above method steps, the timer monitors the working time of the atomization component in real time, which mainly refers to the current accumulated time of the atomization component, that is, all the working time of the atomization component from the last time the electric liquid pump 210 stopped working to the current time period.

[0068] In this way, the control method of the embodiment of the present application can make the liquid volume of the electric liquid pump 210 greater than or equal to the liquid consumption through the above method steps. In this way, the problem of core sticking caused by excessive consumption of liquid in the liquid storage cotton 12 and failure to obtain timely oil replenishment during the use of the electronic atomization device 1 can be effectively avoided.

[0069] In some examples, such as Figure 5As shown, the control method also includes the following steps:

[0070] Step S140: monitor the liquid volume in the liquid storage chamber in real time through the liquid volume sensor, and determine whether the liquid volume is lower than or equal to a second preset threshold.

[0071] Step S150: If the liquid volume is lower than or equal to the second preset threshold, the alarm is controlled to perform an alarm operation.

[0072] It can be understood that, based on the above description, the alarm in the above method steps can be a light alarm, a voice alarm, or even a combination of the two. Therefore, the control neck device performs the above alarm work in the form of voice and / or light to promptly remind the user to perform corresponding fluid replenishment operations on the liquid storage chamber 13 in time.

[0073] In addition, the method step S140 in this example can be specifically performed synchronously with the method step S110 mentioned above, that is, in the embodiment of the present application, the various steps of the electronic atomization device are numbered sequentially through step S110 to step S150, which does not limit the execution order of its method steps. For those skilled in the art, they can make any reasonable adjustments to the execution order of the above-mentioned method steps on the premise that the execution of each method step does not cause conflicts and contradictions. These are all within the inventive concept of this application and are included in the patent protection scope of this application.

[0074] In this way, the control method in this example, through the above method steps, the electronic atomization device can promptly remind the user to perform corresponding liquid replenishment operations on the liquid storage chamber 13 when the liquid level in the liquid storage chamber 13 is low.

[0075] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
