DETAILED DESCRIPTION

[0034] It should be noted that the various embodiments / implementations provided in this application can be combined with each other without causing any contradiction. The detailed description in the specific implementation mode should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0035] In the description of this application, it should be understood that these directional terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application. The term "first / second" is only used to distinguish different objects, and does not mean that there is any similarity or connection between the two.

[0036] One aspect of the present invention provides an electronic atomization device 100. Figures 1 to 3 The electronic atomization device 100 includes an atomization component 1, a liquid storage component 2, a liquid supply channel 3 and an adjustment component 4. Specifically, the electronic atomization device 100 also includes a housing 93, and the atomization component 1, the liquid storage component 2, the liquid supply channel 3 and the adjustment component 4 are all arranged in the housing 93.

[0037] The atomizing assembly 1 is formed with a first atomizing chamber 11a, the liquid storage chamber assembly 2 is formed with a liquid storage chamber 21a, the liquid supply channel 3 is connected with the liquid storage chamber 21a and the first atomizing chamber 11a, and the regulating assembly 4 is arranged on the liquid supply channel 3 to regulate the flow of the liquid supply channel 3. The liquid storage chamber 21a is used to contain and store atomized liquid, and the atomized liquid includes but is not limited to liquid medium such as liquid medicine and smoke liquid. The atomized liquid is atomized in the first atomizing chamber 11a, and the liquid supply channel 3 is used to introduce the atomized liquid in the liquid storage chamber into the first atomizing chamber 11a.

[0038] An electronic atomization device 100 provided in an embodiment of the present application has a liquid supply channel 3 disposed between the atomization component 1 and the liquid storage tank component 2, and there is no direct conduction between the first atomization chamber 11a and the liquid storage tank. At the same time, an adjustment component 4 is disposed on the liquid supply channel 3, and the adjustment component 4 can control the conduction or cutoff of the liquid supply channel 3, which can effectively prevent the residual atomized liquid in the first atomization chamber 11a from directly flowing back into the liquid storage tank, thereby preventing the problem of reduced quality of the unused atomized liquid in the liquid storage tank. On the other hand, the adjustment component 4 can also adjust the flow rate of the atomized liquid flowing from the liquid supply channel 3 into the first atomization chamber 11a. The user can adjust the liquid supply amount by controlling the adjustment component 4 during use to change the amount of fog output from the atomization component 1, thereby further improving the user's experience.

[0039] In one embodiment, please refer to Figures 1 to 3 The electronic atomization device 100 includes a first air circuit 5 and an air pump 6. At least part of the airflow pumped out by the air pump 6 enters the liquid storage tank assembly 2 through the first air circuit 5 to drive the atomized liquid in the liquid storage chamber 21a to enter the liquid supply channel 3. In other words, the electronic atomization device 100 can realize active liquid supply through the air pump 6. The air pressure generated by the air pump 6 after working can enter the liquid storage tank assembly 2 through the first air circuit 5, thereby actively driving the atomized liquid in the liquid storage chamber 21a to enter the liquid supply channel 3. Exemplary, in one embodiment, please refer to Figure 3The liquid storage tank assembly 2 includes an inner liner 21 formed with a liquid storage cavity 21a and a tank shell 22 formed with a placement cavity 22a. The inner liner 21 is arranged in the placement cavity 22a. The first air path 5 connects the placement cavity 22a and the pumping end of the air pump 6. At least part of the airflow pumped by the air pump 6 enters the placement cavity 22a through the first air path 5 to squeeze the inner liner 21, so as to reduce the volume of the liquid storage cavity 21a. Specifically, the tank shell 22 is formed with a tank shell air inlet 22b connected to the placement cavity 22a, a liquid injection port 22d connected to the liquid storage cavity 21a, and a tank shell liquid outlet 22c. The tank shell liquid outlet 22c is connected to the liquid supply channel 3. The first air path 5 is a pipeline structure. One end of the first air path 5 is connected to the pumping end of the air pump 6, and the other end of the first air path 5 is connected to the tank shell air inlet 22b. The inner liner 21 is a soft and stretchable flexible material, including but not limited to latex, rubber, etc. During the process of injecting atomized liquid into the inner tank 21, the volume of the liquid storage chamber 21a gradually expands, thereby playing the role of storing the atomized liquid. When liquid supply is needed, the liquid injection port 22d is closed, and the airflow pumped out by the air pump 6 enters the placement chamber 22a through the first air path 5. The gradually increasing air pressure in the placement chamber 22a will compress the volume of the liquid storage chamber 21a. The atomized liquid stored in the liquid storage chamber 21a is squeezed out from the liquid outlet 22c of the tank shell to the liquid supply channel 3 after being pressurized, and then is transported to the first atomization chamber 11a through the liquid supply channel 3 for atomization, thereby realizing the active liquid supply of the electronic atomization device 100.

[0040] During operation, the traditional electronic atomization device 100 is provided with a ventilation channel connected to the liquid storage tank to ensure the balance of air pressure inside the liquid storage tank and outside air pressure, so as to avoid the situation where the air pressure inside the liquid storage tank is too low to smoothly supply liquid after the atomized liquid in the liquid storage tank is gradually reduced with use. However, this will cause the atomized liquid in the liquid storage tank to come into contact with the outside air. If the atomized liquid is an easily oxidizable liquid medium, the outside air will have a certain impact on the quality of the atomized liquid. At the same time, when the temperature and pressure of the external environment change, the atomized liquid may leak from the ventilation channel.

[0041] Compared with the liquid supply method of the traditional electronic atomization device 100, the liquid supply method of the embodiment of the present application can realize active liquid supply. The air pump 6 actively compresses the inner liner 21 made of flexible material. There is no need to ventilate the liquid storage chamber 21a to balance the air pressure in the liquid storage chamber 21a. The liquid storage chamber 21a has good sealing performance and there is no leakage. Moreover, the atomized liquid in the liquid storage chamber 21a does not come into contact with the outside air throughout the whole process, which can ensure that the quality of the atomized liquid in the liquid storage chamber 21a remains consistent throughout the entire consumption cycle.

[0042] In one embodiment, please refer to Figures 1 to 3The electronic atomization device 100 includes a second air circuit 7, and part of the air flow pumped out by the air pump 6 enters the first atomization chamber 11a through the second air circuit 7 to atomize the atomized liquid in the first atomization chamber 11a. Specifically, the atomization assembly 1 includes a nozzle 11 formed with the first atomization chamber 11a, and the nozzle 11 has a nozzle air inlet 11b, a nozzle liquid inlet 11c and a spray port 11d; the second air circuit 7 is a pipeline structure, one end of the second air circuit 7 is connected to the pumping end of the air pump 6, and the other end of the second air circuit 7 is connected to the nozzle air inlet 11b. The nozzle liquid inlet 11c is connected to the liquid supply channel. After the air pump 6 starts working, a part of the gas pressurizes the placement cavity 22a of the warehouse shell 22 through the first gas path 5, and squeezes the atomized liquid in the liquid storage cavity 21a of the inner tank 21 to be supplied to the first atomizing cavity 11a through the warehouse shell liquid outlet 22c, the liquid supply channel and the nozzle liquid inlet 11c in turn. The other part of the gas is mixed with the atomized liquid in the first atomizing cavity 11a through the second gas path 7 and the nozzle air inlet 11b. After the gas in the first atomizing cavity 11a is mixed with the atomized liquid, smoke with atomized liquid is sprayed out from the spray port 11d to achieve the atomization effect. That is to say, the nozzle can achieve the atomization effect through the two-phase flow atomization principle, that is, the atomized liquid flowing in from the nozzle liquid inlet 11c and the high-speed airflow flowing in from the nozzle air inlet 11b meet in the first atomizing cavity 11a and are atomized into droplets.

[0043] When the atomizing liquid is e-liquid, the viscosity of the e-liquid is significantly affected by temperature. For example, the viscosity of 500CP e-liquid at room temperature (25°C) can reach 1100CP at 15°C, but only 172CP at 40°C. Therefore, it is difficult to achieve a uniform atomization effect when using different e-liquids in the same electronic atomizing device 100. Therefore, in one embodiment, please refer to Figure 1 and Fig. 9 The electronic control module 91 includes a control module 91. Specifically, the control module 91 is a circuit board.

[0044] In one embodiment, please refer to Figure 1, the atomization assembly 1 also includes an atomization core 12 formed with a second atomization chamber 12a, and a heating element 14 disposed on the atomization core 12. Specifically, a suction nozzle 931 is formed on the housing 93, and the atomization core 12 is disposed in the suction nozzle 931. The smoke sprayed from the spray port 11d of the nozzle 11 can enter the atomization core 12 and be heated and atomized into an aerosol by the heating element 14, and the aerosol flows out from the suction nozzle 931 for use by the user. The control module 91 is electrically connected to the heating element 14 to control the heating power of the heating element 14. The heating element 14 can be a grid-shaped heating element disposed on the atomization core 12. Similarly, by electrically connecting the control module 91 to the heating element 14, the heating power of the heating element 14 can be controlled, and the temperature of the heating element 14 can be accurately controlled. The smoke sprayed from the nozzle 11 can be efficiently and controllably atomized in the second atomization chamber 12a to form an aerosol with a smaller particle size for use by the user. That is to say, the atomization component 1 has a double atomization function. The atomized liquid flowing out from the liquid supply channel 3 first enters the first atomization chamber 11a, and then the atomized liquid mixes with the airflow and sprays smoke into the second atomization chamber 12a, thereby realizing primary atomization; the sprayed smoke enters the atomization core 12 and is heated by the heating element 14 and atomized into an aerosol, thereby realizing secondary atomization. The aerosol after secondary atomization flows out from the suction nozzle 931 for use by the user. The particle size after secondary atomization is smaller, which can meet the different taste requirements of users.

[0045] In one embodiment, please refer to Figure 1 , the electronic atomization device 100 includes a one-way valve 8 arranged on the liquid supply channel 3 so that the liquid in the liquid storage chamber 21a flows unidirectionally toward the first atomization chamber 11a. The position where the one-way valve 8 is arranged on the liquid supply channel 3 is not particularly limited. For example, in one embodiment, the one-way valve 8 is arranged on the liquid supply channel 3 and is located between the liquid outlet 22c of the tank shell and the adjustment component 4. When the air pump 6 is not working, the one-way valve 8 closes the liquid supply channel 3. After the air pump 6 is working, the atomized liquid in the liquid storage chamber 21a is pressurized to flow out from the liquid outlet 22c of the tank shell, and pushes the valve core of the one-way valve 8 to move, thereby conducting the liquid supply channel 3, and the atomized liquid can flow unidirectionally toward the first atomization chamber 11a through the one-way valve 8. At the same time, the one-way valve 8 is relatively close to the liquid outlet 22c of the tank shell, which can effectively ensure the quality of the atomized liquid in the liquid storage chamber 21a.

[0046] The type of the one-way valve 8 is not particularly limited, including but not limited to one-way valves 8 of spring type, gravity type, swing type, plastic diaphragm type, etc.

[0047] In one embodiment, when the air pump 6 switches from a stable liquid supply working state to a non-working state where the air pump 6 stops supplying liquid, the delay of the one-way valve 8 in shutting off the liquid supply channel 3 is no more than 0.2s. With this arrangement, the active liquid supply of the liquid storage chamber 21a to the first atomizing chamber 11a can be stopped in time, avoiding the leakage of atomized liquid due to the timely shutoff of the one-way valve 8 after the electronic atomizing device 100 stops working. At the same time, the delay is set to no more than 0.2s, so that the one-way valve 8 shuts off the liquid supply channel 3 more timely, and the user experience is better.

[0048] For example, see Fig.11 , the pressure relief time is simulated and calculated with the air supply pressure of 80KPa. If the delay of the one-way valve 8 in shutting off the liquid supply channel 3 needs to be guaranteed to be within 0.2s, the valve threshold of the one-way valve 8 is set to 60KPa at the lowest, which can realize shutting off the liquid supply channel 3 within 0.2s. At the same time, when the electronic atomization device 100 is not in operation, the one-way valve 8 can effectively avoid leakage caused by the influence of ambient temperature and pressure.

[0049] In one embodiment, please refer to Figure 2 , Figures 4 to 8 The adjustment assembly 4 includes a casing 41 and an adjustment member 42. A main flow channel 41a is formed in the casing 41. The peripheral side wall of the casing 41 and the axial side wall of the casing 41 are both formed with flow ports. Both flow ports are connected to the main flow channel 41a, one of which is connected to the first atomization chamber 11a, and the other is connected to the liquid storage chamber 21a. For details, please refer to Figure 4 The shell 41 is roughly a hollow cylindrical structure, the hollow area inside the shell 41 is the main flow channel 41a, and a flow port is formed at one end of the shell 41 in the axial direction; another flow port is formed on the peripheral side wall of the shell 41; when the flow port on the peripheral side wall of the shell 41 is connected with the first atomization chamber 11a, the flow port on one axial side wall of the shell 41 is connected with the liquid storage chamber 21a; when the flow port on the peripheral side wall of the shell 41 is connected with the liquid storage chamber 21a, the flow port on one axial side wall of the shell 41 is connected with the first atomization chamber 11a; that is, the two flow ports on the shell 41 can be interchangeably connected with the first atomization chamber 11a or the liquid storage chamber 21a.

[0050] See also Figure 4 and Figure 5, at least part of the regulating member 42 is disposed in the main flow channel 41a, and the regulating member 42 rotates around the axial direction of the casing 41 or slides along the axial direction of the casing 41 to adjust the liquid outlet area of ​​at least one flow port. In other words, the regulating member 42 can be disposed entirely in the main flow channel 41a, or partially in the main flow channel 41a, and the regulating member 42 can adjust the liquid outlet area of ​​one or both flow ports by rotating around the axial direction of the casing 41 or sliding around the axial direction of the casing 41 in the main flow channel 41a. The change in the liquid storage area of ​​the flow port can adjust the liquid supply flow rate of the liquid storage chamber 21a flowing into the first atomizing chamber 11a.

[0051] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 5 , the flow port located on one side wall of the casing 41 in the axial direction is the first flow port 41b, the flow port located on the peripheral side wall of the casing 41 is the second flow port 41c, the adjusting member 42 has a fully closed position and a fully open position, when the adjusting member 42 is in the fully closed position, the adjusting member 42 closes the first flow port 41b; when the adjusting member 42 is in the fully open position, the liquid outlet area of ​​the first flow port 41b reaches the maximum; the adjusting member 42 rotates or slides continuously between the fully closed position and the fully open position. In other words, the adjusting member 42 can continuously change the liquid outlet area of ​​the first flow port 41b by continuously rotating or sliding between the fully closed position and the fully open position, thereby realizing stepless regulation of the liquid supply flow rate, and the stepless regulation has higher regulation accuracy, and the user can operate the adjusting member 42 according to the use requirements to realize the regulation of the liquid supply flow rate.

[0052] In one embodiment, please refer to Figure 2 and Figure 4 , the adjusting member 42 is threadedly matched with the casing 41, so that the adjusting member 42 can continuously slide axially relative to the casing 41 during the process of the adjusting member 42 rotating circumferentially relative to the casing 41. Specifically, the adjusting member 42 has a fully closed position that closes the first flow port 41b and a fully open position that avoids the first flow port 41b in the axial sliding direction of the casing 41. In other words, the manner in which the adjusting member 42 is threadedly matched with the casing 41 is not particularly limited. In one embodiment, the adjusting member 42 can be a rod-shaped structure with an external thread on the circumferential side wall, and the inner circumferential wall of the main channel 41a is provided with an internal thread that cooperates with the external thread of the adjusting member 42. The internal thread of the main channel 41a is threadedly sleeved with the external thread of the adjusting member 42, so that the adjusting member 42 can rotate circumferentially relative to the sleeve and continuously slide axially along the casing 41.

[0053] In another embodiment, see Figure 2 and Figure 4The adjusting member 42 includes a rod body 421 and a cover body 422. An installation opening 41d is formed at one axial end of the casing 41 away from the first flow port 41b. One end of the rod body 421 extends into the main flow channel 41a through the installation opening 41d. The cover body 422 is connected to one axial end of the rod body 421 away from the first flow port 41b. The cover body 422 includes a cover plate 4221 connected to one end of the rod body 421 and a surrounding plate 4222 arranged around the outer peripheral side of the cover plate 4221. The inner peripheral wall of the surrounding plate 4222 is threadedly sleeved with the outer peripheral wall of the casing 41. Specifically, in the fully closed position, one end of the rod body 421 away from the installation opening 41d abuts against the first flow port 41b of the casing 41 to close the communication between the first flow port 41b and the main flow channel 41a. In the process of switching from the fully open position to the fully open position, the end of the rod body 421 away from the installation port 41d is separated from the casing 41, and slides relative to the casing 41 in the axial direction away from the first flow port 41b, and the gap between the rod body 421 and the first flow port 41b gradually increases, and finally in the fully open position, when the gap between the rod body 421 and the first flow port 41b reaches the maximum value. In other words, in the process of the adjusting member 42 sliding axially relative to the casing 41, the gap between the adjusting member 42 and the first flow port 41b can be changed to achieve the flow adjustment of the first flow port 41b into the main flow channel 41a.

[0054] The cover plate 4221 of the cover body 422 and a part of the surrounding plate 4222 are both arranged on the outside of the outer shell 93, which makes it easier for the user to operate the adjustment member 42. Through the threaded connection between the cover body 422 and the sleeve 41, the user only needs to tighten or loosen the cover body 422, and the cover body 422 can drive the rod body 421 located in the main channel 41a to slide axially between the fully open position and the fully closed position, so as to achieve the flow adjustment of the first flow port 41b flowing into the main channel 41a.

[0055] In one embodiment, please refer to Figure 4 The cover body 422 and the rod body 421 are an integrally formed structure. With this arrangement, the adjusting member 42 has a higher structural strength.

[0056] In one embodiment, please refer to Figures 5 to 8 The adjusting member 42 rotates continuously between the fully closed position and the fully open position, and a partial circumferential surface of the adjusting member 42 at one end facing the first flow port 41b forms a flow groove 42a, and the end surface of the adjusting member 42 at one end facing the first flow port 41b is an adjusting surface 42b; when the adjusting member 42 is in the fully open position, the adjusting surface 42b is misaligned with at least part of the first flow port 41b, and when the adjusting member 42 is in the fully closed position, the adjusting surface 42b closes the first flow port 41b.

[0057] Specifically, the adjusting member 42 is a rod-shaped structure, the through-flow groove 42a is used to connect the first flow port 41b, the adjusting surface 42b is used to adjust the liquid outlet area of ​​the first flow port 41b, the axial end of the casing 41 formed with the first flow port 41b is a flow plate, and the adjusting surface 42b of the adjusting member 42 abuts against the flow plate. During the circumferential rotation of the adjusting member 42, the adjusting surface 42b can completely close the first flow port 41b or partially close the first flow port 41b or completely displace with the first flow port 41b, thereby continuously changing the liquid outlet area of ​​the first flow port 41b. When the adjusting member 42 is in the fully open position, on the projection plane perpendicular to the axial direction of the casing 41, the liquid outlet area of ​​the first flow port 41b flowing into the through-flow groove 42a reaches the maximum; when the adjusting member 42 is in the fully closed position, the adjusting surface 42b completely closes the first flow port 41b.

[0058] In one embodiment, please refer to Figures 6 to 8 On the projection plane perpendicular to the axial direction of the housing 41, the projection of the first flow port 41b is an arc extending in the circumferential direction. The first flow port 41b is an arc-shaped structure, so that when the adjustment member 42 rotates by a preset angle each time, the change amount of the liquid outlet area of ​​the first flow port 41b each time remains stable, and the user can accurately determine the current liquid outlet area of ​​the first flow port 41b according to the rotation angle of the adjustment member 42.

[0059] In one embodiment, please refer to Figures 6 to 8 , on the projection plane perpendicular to the axial direction of the adjusting rod, the through-flow groove 42a is fan-shaped. Each time the preset angle is rotated, the radius edge of the fan cooperates with the arc structure of the first flow port 41b to uniformly change the liquid outlet area of ​​the first flow port 41b, so that the change amount of the liquid outlet area of ​​the first flow port 41b each time is kept stable, further ensuring that the current liquid outlet area of ​​the first flow port 41b can be accurately determined by the rotation angle of the adjusting member 42, so as to achieve precise adjustment of the liquid supply flow rate.

[0060] By setting the adjustment component 4 on the liquid supply channel 3, the resistance along the liquid supply channel 3 can be changed, so that the liquid supply amount at different viscosities and temperatures can be set to the preset target value, and the preset target value range is between 5mg / 3s and 100mg / 3s. Among them, since the duration of the user's aerosol inhalation is approximately 3 seconds, every 3 seconds is used as the time unit for testing. For details, please refer to Fig.10 , Fig.10 This is a test table for the liquid supply volume of atomized liquids with different viscosities. Fig.10 Two groups of test records of atomized liquids with viscosities of 100CP and 500CP are shown. After the atomized liquids with different viscosities are adjusted by the adjustment component 4, the atomized liquids with different viscosities can maintain the liquid supply within a reasonable range of 76mg / 3s±10%.

[0061] In one embodiment, the electronic atomization device 100 includes a control module 91 , which is connected to the regulating component 4 and the atomization component 1 . The control module 91 adjusts the heating power of the atomization component 1 according to the flow signal of the liquid supply channel 3 adjusted by the regulating component 4 .

[0062] During the atomization process of the atomizer component 1, if the liquid supply flow rate is relatively too large and the heating power of the heating element is too small, the atomization will be insufficient and the atomized droplets will be too large. If the liquid supply flow rate is relatively too small and the heating power of the heating element is too large, the heating element will have a burnt taste after dry burning. In other words, the present application can receive the flow signal of the liquid supply channel 3 adjusted by the adjustment component 4 through the control module 91, and adaptively adjust the heating power of the atomizer component 1 according to the flow signal, so as to achieve preliminary adjustment of the heating power, ensure that the liquid supply flow rate and the heating power of the atomizer component 1 are always in a reasonable range, ensure that the atomized liquid is fully atomized, and the taste of the aerosol is consistent.

[0063] The implementation form of transmitting the flow signal to the control module 91 is not particularly limited. For example, the flow signal can generate an angular displacement signal by rotating the adjustment member 42, and the angular displacement signal can be received by the control module 91 through an optical signal or a resistance signal. The control module 91 can adaptively adjust the heating power of the atomization component 1 according to the optical signal or the resistance signal, thereby realizing the linkage between the liquid supply flow and the heating power of the atomization component 1.

[0064] For example, in one embodiment, please refer to Figure 1 and Fig. 9 The adjustment component 4 includes a sliding rheostat 43 electrically connected to the control module 91. The movement of the adjustment member 42 can drive the sliding rheostat 43 to change the resistance value. The control module 91 adjusts the heating power of the atomization component 1 according to the resistance value of the sliding rheostat 43. Specifically, the adjustment component 4 generates an angular displacement signal by rotating the adjustment member 42. The manner in which the adjustment member 42 drives the sliding rheostat 43 to change the resistance value is not particularly limited.

[0065] In one embodiment, please refer to Figure 1, the sliding rheostat 43 is provided with a first gear 431, and the adjusting member 42 is provided with a second gear 423, the first gear 431 is meshed with the second gear 423 for transmission, and the second gear 423 drives the first gear 431 to rotate, so as to drive the sliding rheostat 43 to change the resistance value. Specifically, a second gear 423 is provided on the outer peripheral wall of the cover body 422 of the adjusting member 42, and the rotation of the adjusting member 42 can drive the second gear 423 to rotate, and the second gear 423 is meshed with the first gear 431 to drive the sliding rheostat 43 to change the resistance value. Since the control module 91 is electrically connected to the heating element 14, when the control module 91 receives the resistance signal of the sliding rheostat 43, the heating power of the heating element 14 of the atomizing assembly 1 is adaptively controlled according to the resistance signal, thereby realizing the linkage between the liquid supply flow rate and the heating power of the atomizing assembly 1.

[0066] For example, the user rotates the adjusting member 42 forward to increase the liquid supply flow rate. The forward rotation of the adjusting member 42 can drive the sliding rheostat 43 to increase or decrease the resistance value. The control module 91 adaptively increases the heating power of the heating element 14 of the atomization component 1 according to the change in resistance value. Similarly, the user rotates the adjusting member 42 reversely to reduce the liquid supply flow rate. The reverse rotation of the adjusting member 42 can drive the sliding rheostat 43 to reduce or increase the resistance value. The control module 91 adaptively reduces the heating power of the heating element 14 of the atomization component 1 according to the change in resistance value. Thereby, the heating power of the atomization component 1 is always matched with the current liquid supply flow rate, thereby optimizing the atomization effect.

[0067] Similarly, the sliding rheostat 43 and the adjusting member 42 can also realize the linkage between the flow signal and the resistance signal through a worm gear transmission, a gear rack transmission, etc.

[0068] In one embodiment, please refer to Figure 1 and Fig. 9, the electronic atomization device 100 includes an air pump 6, an interaction module and a control module 91. The control module 91 is electrically connected to the interaction module, the air pump 6 and the atomization assembly 1 respectively, and the control module 91 is electrically connected to the air pump 6. The interaction module is used to receive input signals and transmit them to the control module 91. The control module 91 adjusts the heating power of the atomization assembly 1 and the output power of the air pump 6 according to the input signals. In other words, the control module 91 is the control core of the electronic atomization device 100. The control module 91 can adjust the heating power of the heating element 14 of the atomization assembly 1 and the output power of the air pump 6 according to actual needs. The interaction module is used to realize signal interaction between the user and the control module 91. Exemplarily, the interaction module is a control panel with a screen and buttons. The user's instructions and signals can be directly transmitted to the control module 91 through the buttons. The control module 91 adjusts the relevant working parameters of the electronic atomization device 100 according to the user's instructions. The working parameters include but are not limited to the heating power of the heating element 14, the output power of the air pump 6, the liquid supply flow rate, etc. The control module 91 can also feedback the relevant working parameters to the screen to provide a visual reference for the user.

[0069] For example, when the atomized liquid is e-liquid, the user can change the particle size of the nozzle 11 after atomization by adjusting the output power of the air pump 6, thereby optimizing the taste. For another example, the particle size of the aerosol flowing out of the mouthpiece 931 can be further reduced by increasing the heating power of the heating element 14, so that the user can get a milder and more delicate taste after inhalation.

[0070] In one embodiment, please refer to Figure 1 and Fig. 9 The electronic atomization device 100 includes a power supply module 92, which is used to supply power to the air pump 6, the atomization assembly 1, the control module 91 and the interaction module. In other words, the power supply module 92 provides the electronic atomization device 100 with the energy required for operation, and the power supply module 92 can be a battery or a power supply circuit directly connected to an external power source.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
