Description

Technical Field

[0001] The present invention relates to the technical field of atomization, and in particular to an electronic atomization device with a power assist function and a control method thereof. Background Art

[0002] An electronic atomization device is an atomization product that uses a heating element such as an atomization core or a heating wire to heat and vaporize a liquid into an aerosol mist. Existing electronic atomization devices usually have a relatively simple structure, mainly including a power supply component and an atomizer. The atomizer is detachably installed in the power supply component. The energy provided by the power supply component is converted into heat energy by the atomizer core in the atomizer, and the liquid in the atomizer is heated to produce an aerosol mist.

[0003] The atomizer of the prior art mainly includes: a container for containing liquid, an atomizer core (usually a porous ceramic substrate) for atomizing the liquid, and a microphone activated by air pressure. Usually, the microphone triggers the atomizer to start atomization by external suction, which creates negative pressure inside the electronic atomizer device, that is, at the microphone. When the negative pressure value reaches the triggering threshold of the microphone, the microphone is activated, and then the power supply component supplies power to the atomizer core, and the atomizer core heats the liquid to atomize it.

[0004] At present, the electronic atomization device of the prior art needs to start the microphone when external suction is performed, which requires a large suction force to achieve, which is not only laborious, but also affects the user's experience of inhaling aerosol mist. In addition, sometimes after the user stops inhaling, the aerosol mist inside the shell is not discharged from the outside of the shell in time, and some residues remain inside the shell; the aerosol mist remaining inside the shell will form condensate when it is cooled, and remain inside the shell; because there is still condensate remaining in the airway during suction, the condensate will be sucked into the mouth when the microphone is started. In severe cases, harmful condensate will be directly inhaled into the lungs, which seriously causes a poor user experience. Therefore, the electronic atomization device of the prior art is in urgent need of further improvement. Summary of the invention

[0005] In view of this, an embodiment of the present invention provides an electronic atomization device with a power assist function and a control method thereof, so as to solve the technical problem that the existing electronic atomization device requires a large suction force to activate the microphone during suction, resulting in a poor user experience.

[0006] The present invention provides an electronic atomization device with a power-assisted function, the device comprising:

[0007] A shell, wherein a negative pressure chamber is formed inside the shell;

[0008] an atomizer, disposed in the housing, and used for atomizing liquid to form gas;

[0009] A microphone, wherein the microphone is used to trigger the atomizer to work under the negative pressure generated by the negative pressure chamber;

[0010] A power module is disposed in the shell and communicated with the negative pressure chamber, and is used to generate power to discharge the gas in the negative pressure chamber to the outside of the shell.

[0011] Furthermore, the device also includes an airway, which is connected to the negative pressure chamber.

[0012] Furthermore, the air channel includes a first air channel, and the first air channel and the negative pressure chamber are located on a first side of the power module; the airflow generated by the power module passes through the negative pressure chamber and the first air channel in sequence from the first side.

[0013] Furthermore, the air passage includes: a second air passage, and the second air passage is located on a second side of the power module opposite to the first side.

[0014] Furthermore, the pressure value formed by the power module in the negative pressure chamber is less than or equal to the triggering pressure value of the microphone.

[0015] Furthermore, the device also includes: a power switch, which is arranged outside the shell and is used to control the power module to be turned on and / or off.

[0016] Another aspect of the present invention provides a control method for an electronic atomization device, which is applied to any of the electronic atomization devices described above; the method comprises:

[0017] Activate the electronic atomization device;

[0018] The start-up power module is in standby mode;

[0019] The current instruction is obtained, and the power module is controlled to generate an airflow in a specified direction according to the current instruction, so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the shell.

[0020] Further, obtaining the current instruction and controlling the power module to generate an airflow in a specified direction according to the current instruction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the shell includes: if the current instruction is a suction instruction, controlling the power module to generate power in a first direction for reducing the suction force of the starting microphone, and controlling the gas in the negative pressure chamber to be discharged to the outside of the shell along the first direction.

[0021] Further, obtaining the current instruction and controlling the power module to generate an airflow in a specified direction according to the current instruction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the shell includes: if the current instruction is an exhaust instruction, controlling the power module to generate power in a second direction different from the first direction so that the gas in the negative pressure chamber is discharged to the outside of the shell along the second direction.

[0022] Furthermore, the first direction is opposite to the second direction.

[0023] Furthermore, the method further includes a current instruction determining step before obtaining the current instruction and controlling the power module to generate an airflow in a specified direction according to the current instruction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the housing, and the current instruction determining step includes:

[0024] Obtaining the magnitude of the external suction force on the gas in the negative pressure chamber;

[0025] If the suction force is greater than or equal to a preset value, determining that the current instruction is a suction instruction;

[0026] If the suction force is smaller than a preset value, the current instruction is determined to be an exhaust instruction.

[0027] In summary, the beneficial effects of the present invention are as follows:

[0028] On the first aspect, the present invention is provided with a power module to assist the airflow movement, so that the auxiliary microphone is started during inhalation, and only a small suction force is required to start the microphone, so that the atomization core of the entire atomizer begins to heat the liquid. In addition, for some deep users, such as users who use lung inhalation to produce a large amount of aerosol mist, even lung inhalation does not require the user's lung capacity, and can be achieved more easily; at the same time, due to the existence of the power module, the condensed liquid in the airway can be discharged outside the shell without the user's participation when the atomizer is not inhaled; the residual gas in the shell is reduced to form condensed liquid; therefore, the user will not inhale the condensed liquid when inhaling, which greatly improves the user experience.

[0029] Secondly, since the invention controls the generation of airflows in different directions through different current instructions, and different airflow directions can discharge the gas outside the shell, the current instruction is determined according to the current user's usage status, so that the gas is discharged from different directions. When suction is performed, the gas is discharged from the first airway to assist suction; when suction is stopped, the gas is discharged from the second airway to avoid unnecessary gas being discharged from the first airway and choking the user; thus improving the user experience in many ways.

[0039] The present invention provides an electronic atomization device with a power-assisted function, comprising:

[0040] A shell having a negative pressure chamber formed therein;

[0041] an atomizer, disposed in the housing, and used for atomizing liquid;

[0042] A microphone, the microphone being used to trigger the atomizer to work under the negative pressure generated by the negative pressure chamber;

[0043] A power module is disposed in the shell and communicated with the negative pressure chamber, and is used to generate power to discharge the gas in the negative pressure chamber to the outside of the shell.

[0044] The present invention is provided with a power module to assist airflow movement, so that the auxiliary microphone is started during inhalation, and only a small suction force is needed to start the microphone, so that the atomization core of the entire atomizer begins to heat the liquid. In addition, for some deep users, such as users who use lung inhalation to generate a large amount of aerosol mist, even lung inhalation does not require the user's lung capacity and can be achieved more easily; at the same time, due to the existence of the power module, the condensed liquid in the airway can be discharged from the airway when the atomizer is not inhaling without the user's participation, and the user will not inhale the condensed liquid when inhaling, which greatly improves the user experience.

[0045] The following is combined with Figure 1 -Attached Figure 5 The functions and effects of the power module of the electronic atomization device of the present invention are further described in detail.

[0046] Embodiment 1

[0047] See also Figure 1 and Figure 2 The first embodiment of the present invention provides an electronic atomization device with a power-assist function. The power-assist function in the first embodiment refers to adding a power module to the electronic atomization device, which can assist the electronic atomization device when it is working, reduce the suction force used by the user to start the microphone, and assist in suction. The electronic atomization device includes:

[0048] A housing 1, wherein a negative pressure chamber 11 is formed in the housing;

[0049] An atomizer is disposed in the housing 1 and is used to atomize the liquid;

[0050] Microphone 5, which is used to trigger the atomizer to work under the negative pressure generated by the negative pressure chamber 11;

[0051] The power module 6 is disposed in the shell 1 and communicated with the negative pressure chamber 11 , and is used to generate power to discharge the gas in the negative pressure chamber 11 to the outside of the shell 1 .

[0052] Furthermore, the device also includes: an airway, which is connected to the negative pressure chamber.

[0053] In this embodiment, when the user inhales, the microphone 5 senses the inhalation action, the microphone is activated, and the battery power supply set in the shell starts the voltage output to the atomizer. In this embodiment, when the user inhales, the gas in the negative pressure chamber 11 flows along the direction of arrow A, and at the same time, the power module 6 generates power to push the airflow into the negative pressure chamber 11 along the direction of arrow C, and then discharges it to the outside of the shell in the airway along the direction of arrow A. Therefore, negative pressure is formed in the negative pressure chamber, and the gas at the microphone 5 moves along the direction of arrow D. If the trigger pressure of the microphone 5 is F 触 ; The negative pressure generated when the user inhales is F 吸 ; Generally speaking, when F 吸 ≥F 触 When the microphone 5 is activated, the power supply inside the housing 1 outputs voltage to the atomizer through the electrodes provided on the housing 1. When the user inhales, the power module 6 generates a corresponding pressure of F according to the user setting. 动 ; At this time F 吸 +F 动 is the pressure of the entire negative pressure chamber 11. At this time, the negative pressure chamber 11 is connected to the microphone 5. The pressure of the negative pressure chamber 11 acts on the microphone 5, which is equivalent to the microphone 5 being subjected to the suction negative pressure and the pressure of the power module 6 at the same time. Therefore, when F 吸 +F 动 ≥F 触 ; then the microphone 5 is started. It can be seen that when the power module 6 is turned on, the user's suction force will be reduced, and the specific reduction in suction force can be controlled by controlling the output of the power module 6 according to the user's needs; the present invention is provided with a power module 6 to assist the airflow movement, thereby increasing the negative pressure value of the negative pressure chamber 11, and then the power required when the user sucks or the external machine sucks is relatively reduced. Therefore, the user or the external machine does not need too much power to start the microphone, which solves the technical problem of the electronic atomization device sucking hard in the prior art and has the effect of enhancing the user's experience.

[0054] In the present invention, the power module 6 is arranged inside the shell 1, and the power module 6 includes: a fan blade and a motor. The direction of the fluctuating airflow of the power module 6 can generate a forward or reverse airflow according to the reversal of the motor. The airflow flowing in the direction of the first air duct 4 is defined as forward, and the reverse direction is reverse. According to the size of the shell 1 in the atomization device, the power module 6 can be set to a motor plus an eccentric wheel. Since it is difficult to install small fan blades in a small device, the motor plus an eccentric wheel is set to generate airflow, while reducing the volume of the electronic atomization device, which is convenient for users to carry with them, thereby helping to enhance the user experience.

[0055] Furthermore, the device comprises: a first accommodating portion 2 for accommodating the atomizer; and a second accommodating portion 3 for accommodating the microphone 5; the first accommodating portion 2 and the second accommodating portion 3 are arranged correspondingly.

[0056] In this embodiment, the atomizer and the container for containing liquid (not shown in the figure, this technology is existing technology, as long as it can achieve atomization and contain liquid, it will not be repeated here) are arranged in the first accommodating part 2, and the second accommodating part 3 also contains a power module for powering the entire atomizing device and a control board 8 for controlling the entire device. The first accommodating part 2 and the second accommodating part 3 are arranged correspondingly, so that the atomizer inside the first accommodating part 2 can correspond to the microphone 5 in the second accommodating part 3, can quickly respond to the reaction of the microphone 5, and then can quickly start the atomizer for heating; the first accommodating part 2 and the second accommodating part 3 are detachably connected, and when the liquid in the atomizer is exhausted, a new atomizer can be replaced.

[0057] Furthermore, the power module 6 is disposed in the first accommodating portion 2 or the second accommodating portion 3 .

[0058] In this embodiment, the power module 6 may be arranged in the first accommodating portion 2, and the power module 6 generates suction force to suck the airflow from the microphone 5 in the second accommodating portion 3 to the first air passage 4, and then discharge it from the first air passage 4 to the outside of the housing 1. When the power module 6 is arranged in the second accommodating portion 3, the power generated by the power module 6 is a blowing force, which blows the gas in the negative pressure chamber 11 to the first air passage 4, and then discharges it from the first air passage 4. The power module 6 may be arranged in the first accommodating portion 2 or the second accommodating portion 3, as long as the direction of the airflow from the negative pressure chamber 11 to the first air passage 4 in the present invention can be achieved.

[0059] In one embodiment, the first accommodating portion 2 and the second accommodating portion 3 are both provided with a notch at one end facing each other, and the notches cooperate with each other to form a negative pressure chamber 11, which is connected to the first airway 4 and the microphone 5; that is, the negative pressure chamber 11 is arranged above the microphone 5 and below the first airway 4, so that the airflow flows from bottom to top in the figure to the suction nozzle for suction, which facilitates the movement of the gas. The second accommodating portion 3 is provided with a concave cavity 31, and the concave cavity 31 and the outer wall of the first accommodating portion 2 form the negative pressure chamber 11.

[0060] Furthermore, the microphone 5 is located at an end of the second accommodating portion 3 away from the negative pressure chamber 11 .

[0061] In this embodiment, the microphone 5 is away from the negative pressure chamber 11 to prevent excessive local pressure in the negative pressure chamber 11 from directly acting on the microphone 5 and causing the microphone 5 to be triggered incorrectly, thereby causing the atomizer to start heating the atomized liquid.

[0062] Furthermore, a chamber for accommodating the microphone 5 is disposed in the second accommodating portion 3 , and a flow channel 32 communicating with the chamber and the negative pressure chamber 11 is disposed in the second accommodating portion 3 .

[0063] In this embodiment, a pressure chamber is formed on one side of the microphone 5 for the microphone 5 to sense pressure; the gas flows from the pressure chamber through the flow channel 32 to the negative pressure chamber 11, and then flows out of the housing 1 through the first air channel 4. By providing the pressure chamber and the flow channel 32, the time for the pressure in the negative pressure chamber 11 to act on the microphone 5 is extended, which is conducive to improving the uniformity of the negative pressure chamber 11 acting on the microphone 5, improving the accuracy of the microphone 5 starting, and reducing the false triggering of the microphone 5.

[0064] Furthermore, the power module 6 is disposed in the second accommodating portion 3 , and the power module 6 is disposed corresponding to the microphone 5 .

[0065] In this embodiment, the power module 6 is arranged on the side of the chamber away from the negative pressure area of ​​the microphone 5, and the power module 6 is also provided with a channel connected to the negative pressure chamber 11. The airflow generated by the power module 6 passes through the channel and then passes through the negative pressure chamber 11, forming an airflow in the negative pressure chamber 11, and then forming a negative pressure, sucking the gas at the microphone 5, so that the microphone 5 is in a negative pressure state. The power module 6 is arranged in the second accommodating part 3, and the second accommodating part 3 is provided with a battery, etc., so that the power module 6 can work without too many other devices.

[0066] Furthermore, the pressure value formed by the power module 6 in the negative pressure chamber 11 is less than or equal to the triggering pressure value of the microphone 5 .

[0067] In this embodiment, when F 动 ≥F 触When the microphone 5 is triggered, the user or an external power mechanism does not need to generate power. If the negative pressure generated by the power module 6 is greater than the threshold for triggering the microphone 5, the microphone 5 automatically starts the atomizer, which causes the atomizer to always remain in atomization when the user does not need to inhale, thereby causing waste of atomized liquid. In order to avoid waste of atomized liquid, the microphone 5 is set to a state where the pressure required to activate the microphone is at a critical value. When the user needs to inhale gas, the microphone can be activated by just gently inhaling.

[0068] Furthermore, the device also includes a power switch, which is arranged outside the housing 1 and is used to control the power module 6 to be turned on and / or off.

[0069] In this embodiment, a switch is set to be turned on and off, so that the user can directly control the pressure of the negative pressure chamber 11. When the suction needs to be controlled, the power module 6 is turned on, and when it is not needed, it is turned off to avoid the power module 6 generating excessive pressure, which directly causes the microphone 5 to be triggered by mistake and causes a waste of resources.

[0070] Embodiment 2

[0071] See also Figure 3 and Figure 4 , the parts of the second embodiment of the present invention that are the same as the aforementioned first embodiment will not be repeated here. The main difference is that the function of the power module has been further extended. In addition to the auxiliary suction as described in the first embodiment, the power module can absorb the residual gas in the airway during the idle time when the user is not sucking the electronic atomization device, thereby reducing the condensation of the condensate in the shell, so that there is no condensate in the first airway. Specifically, the electronic atomization device of the second embodiment includes: a shell 1, a negative pressure chamber is formed in the shell; an atomizer, which is arranged in the shell 1, and the atomizer is used to atomize the liquid to form gas; a microphone, the microphone triggers the atomizer to work under the action of the negative pressure generated in the negative pressure chamber; a power module 6, the power module 6 is connected to the negative pressure chamber 11, and is used to control the gas in the negative pressure chamber to be discharged from the shell 1 to the outside of the shell 1 according to instructions.

[0072] Furthermore, the first air channel 4 and the negative pressure chamber are located on the first side of the power module 6; the airflow generated by the power module passes through the negative pressure chamber and the first air channel from the first side in sequence. If the instruction is a suction instruction, the airflow generated by the power module 6 passes through the negative pressure chamber and the first air channel 4 from the first side in sequence.

[0073] In this embodiment, if Figure 4As shown, the airflow formed by the power module can flow forward or backward along the direction of the arrow. The device also includes a microphone 5, which triggers the atomizer according to the pressure inside the shell 1. The pressure on the microphone 5 is the sum of the external suction force and the pressure generated by the power module 6. When the person stops sucking the atomizer, the atomizer stops atomizing the liquid, and the gas atomized by the atomizer usually remains inside the shell 1; therefore, when the user stops sucking, the microphone starts working and controls the power module to continue working. At this time, F 吸 Equal to 0, the power module continues to work, F 动 The airflow in the negative pressure chamber is continuously pushed to discharge the residual gas from the negative pressure chamber to the outside of the housing 1, reducing the gas remaining in the housing, thereby reducing the formation of condensate. In addition, the power module 6 is immediately started to discharge the gas outside the housing 1, reducing the time the gas stays inside the housing 1, thereby reducing the problem of condensate forming inside the housing 1 and affecting the taste of the next draw, further improving the user experience.

[0074] Furthermore, a first air passage 4 is provided on the shell 1 , and the first air passage 4 connects the inside of the shell 1 with the outside of the shell 1 ; the first air passage 4 is used for an external power source to absorb gas.

[0075] In this embodiment, the external power source can be a person or an external power mechanism, such as a suction fan. A first air duct 4 is provided, and the user inhales gas. In addition, the power module 6 discharges the gas from the first air duct 4 to the outside of the shell 1. In addition, the power module 6 can also assist the user in suction. When the user inhales, the power module 6 is started to discharge the gas outside the shell 1, which is beneficial for the user to inhale, and the gas can be inhaled without too much force. Therefore, in this embodiment, when the user or the external machine inhales, the power module 6 is started to assist in suction. When the user or the external machine stops inhaling, the power module 6 continues to work until all the gas inside the shell 1 is cleared and the power module 6 is turned off. In addition, a smoke detector can also be provided inside the shell 1 to detect the content of the atomized gas in the negative pressure chamber 11. If the content value drops to a certain value, the power module 6 is turned off.

[0076] Furthermore, the air passage includes, in addition to the first air passage 4, a second air passage 7, which is located at a second side of the power module 6 opposite to the first side. If the instruction is an exhaust instruction, the airflow generated by the power module 6 flows from the negative pressure chamber 11 through the power module 6 and then through the second air passage 7.

[0077] In this embodiment, the second air duct 7 is arranged in a chamber connected to the power module 6, and the second air duct 7 is arranged at one end away from the first air duct 4. Since the first air duct 4 is used for external suction, the second air duct 7 is arranged away from the first air duct 4, and the first air duct 4 is no longer used to discharge exhaust gas, thereby avoiding that when the user stops inhaling, the power module 6 forcibly discharges the residual gas into the user's suction part, resulting in a decrease in user experience.

[0078] Furthermore, the axial direction of the second air passage 7 is arranged at an acute angle with the axial direction of the housing 1 , and the port of the second air passage 7 communicating with the housing 1 is located at the lower end.

[0079] In this embodiment, the second air duct 7 is arranged at an angle, which is beneficial to gas discharge. In addition, if part of the atomized gas condenses on the inner wall of the shell 1, it can also slide along the inner wall of the second air duct 7 and leave the inside of the shell 1, further preventing the formation of condensate inside the shell 1, which is beneficial to extending the service life of the electronic components inside the shell 1.

[0080] Furthermore, the pressure value formed by the power module 6 in the negative pressure chamber 11 is less than or equal to the trigger (starting) pressure value of the microphone 5 .

[0081] In this embodiment, when F 动 ≥F 触 When the microphone 5 is activated, the user or an external power mechanism does not need to generate power. If the negative pressure generated by the power module 6 is greater than the threshold of the trigger of the microphone 5, the microphone 5 automatically controls the voltage output to the atomizer, which causes the atomizer to continue to produce atomized gas when the user does not need to inhale. In order to avoid wasting atomized liquid, the microphone 5 is set to a critical state that is just triggered. When the user needs to inhale gas, he can directly inhale.

[0082] In other embodiments of the present invention, the power module includes: a first power module, which is used to provide airflow as power for the negative pressure chamber and the first airway; and a second power module, which is used to generate suction force, and the suction airflow flows out through the second airway. The first power module assists suction, and the second power module realizes suction. The two power modules work separately and independently.

[0083] Embodiment 3

[0084] Embodiment 3 of the present invention provides a control method of an electronic atomization device, which is used to control the electronic atomization device of Embodiment 1 or Embodiment 2; Figure 5 As shown, the method includes:

[0085] S1: Start the electronic atomization device;

[0086] The atomizer device can be started by setting a switch or by clicking an icon on the screen through a touch button. After being started, the electronic atomizer device is in a standby state. When suction occurs, when the suction force reaches a certain size, the microphone is started, and the entire electronic atomizer device enters a working state.

[0087] S2: The start-up power module is in standby state;

[0088] The power module can be started manually through an external power switch or by setting a pressure switch. When the external suction force reaches a certain value, the power module is automatically started, so that the electronic atomization device is in working state. The specific power value generated by the power module can be set as needed.

[0089] S3: Obtain the current instruction, and according to the current instruction, control the power module to generate an airflow in a specified direction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the shell.

[0090] The current instruction can be set as needed. In this embodiment, the current instruction is set to be a suction instruction or an exhaust instruction. The current instruction means obtaining the current state of the electronic atomization device, including when suction is in progress and when suction stops. Specifically, the acquisition of the current instruction can be triggered by an external power switch, such as setting a button on the outside of the shell, and sending the current instruction information by pressing the button.

[0091] The power module generates airflow in a specified direction, which means that, according to the current instructions, the control generates airflow in a direction that matches the current instructions to meet the current instructions and improve the user experience.

[0092] Since the present invention controls the generation of airflows in different directions through different current instructions, and different airflow directions can discharge the gas outside the shell. Therefore, according to the current user's usage status, the current instruction is determined to discharge the gas from different directions. When suction is performed, the gas is discharged from the first airway to assist suction; when suction is stopped, the gas is discharged from the second airway to avoid unnecessary gas being discharged from the first airway and choking the user. The user experience is improved in many ways.

[0093] Further, obtaining the current instruction and controlling the power module to generate an airflow in a specified direction according to the current instruction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the shell include: if the current instruction is a suction instruction, controlling the power module to generate a first direction for reducing the power for starting the microphone suction force, and controlling the gas in the negative pressure chamber to be discharged to the outside of the shell along the first direction.

[0094] In this embodiment, when suction is performed, the power module is controlled to generate power in the first direction, which is used to reduce the negative pressure when the microphone is activated; the first direction is to flow from the negative pressure chamber through the first airway and out of the shell. At this time, the user is in the suction state, which reduces the suction force of the activated microphone to improve the user's experience; the principle is consistent with the above-mentioned embodiment 1, and will not be repeated here.

[0095] Further, obtaining the current instruction and controlling the power module to generate an airflow in a specified direction according to the current instruction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the shell includes: if the current instruction is an exhaust instruction, controlling the power module to generate power in a second direction different from the first direction so that the gas in the negative pressure chamber is discharged to the outside of the shell along the second direction.

[0096] In this embodiment, specifically, when the suction is completed in the second direction, the power module is controlled to generate power in the second direction opposite to the first direction, so as to discharge the gas from the second air passage to reduce the gas residue in the shell and form condensate. Of course, it is worth noting that in other embodiments, if the current instruction is an exhaust instruction, the gas can also be discharged along the first direction to reduce the gas residue in the shell from condensing to form condensate.

[0097] Furthermore, the first direction is opposite to the second direction.

[0098] In this embodiment, the first direction and the second direction can be achieved by rotating the power module forward and reversely, without the need to set up too many power devices. In other embodiments, if the first direction and the second direction are not opposite, but just different, in this case, a first power module can be set to generate power in the first direction, and a second power module can be set to generate power in the second direction different from the first direction.

[0099] Furthermore, the method further includes a current instruction determining step before obtaining the current instruction and controlling the power module to generate an airflow in a specified direction according to the current instruction so that the gas in the negative pressure chamber is discharged from the specified direction to the outside of the housing, and the current instruction determining step includes:

[0100] Obtaining the magnitude of the external suction force on the gas in the negative pressure chamber;

[0101] If the suction force is greater than or equal to a preset value, determining that the current instruction is a suction instruction;

[0102] Assume that the preset value is F1; the pressure of the microphone 5 triggering the atomizer is F3; the pressure generated by the power module 6 in the negative pressure chamber 11 is F2; ​​when F3=F1+F2, the microphone 5 just triggers the atomizer. Generally speaking, F3 and F2 are fixed values. Therefore, when the suction force is equal to F1, at this time, starting the power module 6 just triggers the microphone 5 to assist the user in inhaling. When the suction force of the microphone 5 is greater than F1, it is considered that the second state of the current atomization device is in the state of suction; therefore, the exhaust direction of the power module 6 is controlled to be discharged from the first airway 4 to assist the user inhaling, thereby reducing the energy consumption of the user or external power; enhancing the user experience.

[0103] If the suction force is less than the preset value, the current instruction is determined to be an exhaust instruction. If the suction force is less than F1, it is considered that the atomizer is in the third state at this time, and it is necessary to start the power module 6 to discharge the gas from the second airway 7. Due to the suitability of suction, the power module 6 assists in suction. When the user stops suctioning, the user cancels the suction force. At this time, the suction force is less than F1; if the exhaust direction of the power module 6 is controlled, the gas is prevented from escaping from the first airway 4 and choking the user; the user's experience is enhanced.

[0104] In this embodiment, the exhaust direction of the power module 6 is adjusted according to the suction force. According to the suction force, it is determined whether the current atomization device is in a suction state. According to the current state of the atomization device, the exhaust direction of the power module 6 is controlled to improve the user experience.

[0105] In this embodiment, the suction force is acquired in real time. When the suction force changes, the direction of the power module 6 is immediately controlled to switch between the suction command and the exhaust command, thereby enhancing the user experience.

[0106] Before the step of obtaining the magnitude of the external suction force on the gas in the negative pressure chamber, it also includes: detecting the content of the gas generated by atomization inside the shell 1; if the gas content reaches a preset value, the step of obtaining the magnitude of the external suction force on the gas in the negative pressure chamber is executed. Since the suction force of the electronic atomization device is 0 when it is in the closed state, if the power module is controlled to be turned on at this time, it will cause a waste of resources and even trigger the microphone by mistake. Therefore, only when the content value inside the shell reaches a certain value, the power module is started, further making the electronic atomization device more intelligent.

[0107] In an improved embodiment, in order to achieve accurate control of the microphone, the control method of the electronic atomization device of the present invention may further include the following steps:

[0108] Calculating the flow velocity of the gas in the negative pressure chamber according to the magnitude of the suction force;

[0109] Determine whether the flow velocity meets the preset flow velocity value;

[0110] If the flow velocity of the gas is greater than or equal to S1, it is considered that the gas flows out of the outside of the housing 1 under the combined action of an external force and an external power suction, or when the user sucks alone; if the flow velocity of the gas is less than S2, it is considered that the gas is not affected by an external force and freely overflows to the outside of the housing 1; if the flow velocity of the gas is less than S1 and greater than or equal to S2, it is considered that only the power module 6 acts on the gas to discharge the gas. Therefore, when the flow velocity of the gas is lower than S1, it is necessary to control the power module 6 to discharge the generated gas to the outside of the housing 1. Among them, S2 < S1. It should be noted that when controlling the power module 6 to discharge the gas to the outside of the housing 1, if the flow velocity of the gas is less than S1 and greater than or equal to S2, at this time, the pressure generated by the power module cannot directly trigger the atomizer, and it is necessary for the power module 6 to discharge the gas generated by the atomizer, and the power module 6 plays the role of discharging waste gas.

[0111] If so, control the power module 6 to discharge the gas atomized by the atomizer to the outside of the housing 1.

[0112] In this embodiment, the flow velocity of the gas is obtained and compared with the preset flow velocity value to obtain the current state of the atomization device. The states of the atomization device include: First: The atomizer does not work and there is no residual gas in the housing 1. Second: The atomizer continuously atomizes the liquid (that is, a suction instruction needs to be started). And third: The atomizer stops atomizing and there is residual gas inside (that is, an exhaust instruction needs to be started). At the beginning, the flow velocity of the gas is 0, and at this time, the atomization device is in the first state. When the user starts to suck, the power module is in the working state. At this time, the flow velocity of the gas is greater than or equal to S1, and at this time, the atomization device is in the second state. When the flow velocity is less than S2, at this time, the atomization device is in the third state. Therefore, when the user stops sucking, there is gas inside the housing 1 at this time, and it slowly flows out of the housing 1. At this time, the flow velocity of the gas is less than S2 and greater than 0; then control the power module 6 to blow or suck the gas to make the flow velocity of the gas greater than S2 and less than S1, which plays the role of discharging the gas, reduces the gas remaining inside the housing 1, and further reduces the formation of condensate inside the housing 1. Solve the technical problem of easy formation of condensate in the atomization device in the prior art.

[0113] Furthermore, in this embodiment, if the user sucks the gas inside the housing 1, at this time, control the power module 6 to blow the gas to make the flow velocity of the gas greater than S2; thus playing the function of assisting the user to suck. The whole atomization device not only has the advantage of reducing the formation of condensate, but also has the advantage of assisting the user or an external power to suck the gas; greatly enhancing the user experience.

[0114] In order to accurately determine whether the atomization device is currently in the third state, before the step of controlling the power module 6 to discharge the gas generated by the atomizer to the outside of the shell 1, it also includes: judging whether the gas flow rate suddenly changes according to the flow rate, and if so, executing the control power module 6 to discharge the gas generated by the atomizer to the outside of the shell 1.

[0115] In this embodiment, the sudden change means that the flow rate of the airflow suddenly decreases. The flow rate of the gas is obtained in real time, and the flow rates of the gas before and after are subtracted. If it exceeds the preset value, it is considered that the flow rate of the airflow has suddenly changed (in addition, it can also be used to determine whether the magnitude of the suction force has suddenly changed). If the flow rate of the gas suddenly changes, that is, it suddenly decreases, it indicates that the external suction has stopped. At this time, the microphone 5 is closed, and the power module 6 is controlled to discharge the gas outside the shell 1, which reduces the residence time of the gas in the shell 1, which is conducive to reducing the formation of condensate inside the shell 1. In other embodiments, it is also possible to determine whether the power module 6 needs to be started by detecting whether the microphone 5 is closed and combining the content of the gas in the airway inside the shell 1.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
