[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] See also Figure 1 and Figure 2 , the electronic atomization device 10 provided by an embodiment of the present invention includes an atomizer 101 and a power supply 300, and the atomizer 101 includes an atomization assembly 100 and a magnetic assembly 200. An airflow channel 110 is provided in the electronic atomization device 10, and the airflow channel 110 is a channel for external air to enter the inside of the electronic atomization device 10 from at least one inlet and reach the outlet for the user to inhale. The electronic atomization device 10 may include one or more airflow channels 110, for example, the airflow channels 110 are all opened on the atomization assembly 100, the magnetic assembly 200 can be located inside the airflow channel 110, or the magnetic assembly 200 is located outside the airflow channel 110 and is arranged near the port of the airflow channel 110, and the power supply 300 is arranged relative to the atomization assembly 100.

[0034] In some embodiments, the atomizer assembly 100 is used to store the aerosol generating substrate and heat the aerosol generating substrate for atomization. The smoke formed by the atomization of the aerosol generating substrate can flow in the air flow channel 110. The upper end of the air flow channel 110 forms a suction nozzle 112 on the atomizer assembly 100, and the suction nozzle 112 is connected to the outside.

[0035] The atomizer assembly 100 is also provided with an air inlet 121, for example, the air inlet 121 is arranged on the side or bottom surface of the atomizer assembly 100, and the air inlet 121 is arranged away from the mouthpiece 112. The air inlet 121 connects the airflow channel 110 with the outside. When suction is performed from the mouthpiece 112, the outside air enters the airflow channel 110 from the air inlet 121 to form a suction airflow, and the suction airflow passes through the airflow channel 110 to carry the smoke after the aerosol generation matrix is ​​atomized and enters the user's mouth through the mouthpiece 112, thereby realizing the user's suction of the smoke.

[0036] The power supply 300 is connected to the atomizer assembly 100. The power supply 300 includes a battery 310, a sensing unit 320, a processing unit 330 and a housing. The battery 310, the sensing unit 320 and the processing unit 330 are all accommodated in the housing. The sensing unit 320 can be accommodated in the housing or installed on the atomizer assembly 100. The sensing unit 320 and the processing unit 330 are both electrically connected to the battery 310. When the battery 310 heats the atomizer assembly 100, the atomizer assembly 100 atomizes the aerosol generating matrix, and the atomized smoke is inhaled by the user through the mouthpiece 112. When the battery 310 stops heating the atomizer assembly 100, the atomizer assembly 100 stops atomizing the aerosol generating matrix, and the atomizer assembly 100 will not generate smoke for the user to inhale. The sensing unit 320 may be a magnetic sensor, etc., and the processing unit 330 may be a single-chip microcomputer (MCU), etc. The sensing unit 320 is used to sense a changing magnetic field signal (the changing magnetic field signal includes a change in the direction of the magnetic field, a change in the magnitude of the magnetic field, and a simultaneous change in the direction and magnitude of the magnetic field), and transmit the changing magnetic field signal to the processing unit 330. The processing unit 330 is used to analyze and determine the changing magnetic field signal. The processing unit 330 can control whether the battery 310 heats the atomization component 100, thereby achieving the purpose of atomizing the aerosol generation matrix.

[0037] When the magnetic component 200 is located in the air flow channel 110, the magnetic component 200 can be located near the power supply 300. When the user takes a puff at the mouthpiece 112, the magnetic component 200 can move relative to the atomizer component 100 under the impetus of the suction airflow, and the sensing unit 320 receives the changing magnetic field signal generated by the movement of the magnetic component 200. In some embodiments, the sensing unit 320 is arranged at a position where the battery 310 is close to the atomizer component 100, for example, the sensing unit 320 is arranged below the atomizer component 100. This facilitates the sensing unit 320 to accurately and quickly sense the changing magnetic field signal generated by the movement of the magnetic component 200, thereby improving the sensitivity of the sensing unit 320 and the response speed of the entire electronic device to the user's puff.

[0038] The processing unit 330 has a good filtering function. In the process of analyzing the changing magnetic field signal, the processing unit 330 can accurately determine whether the changing magnetic field signal is a normal suction signal generated by the user's inhalation airflow pushing the magnetic component 200 to move. For example, when the magnetic component 200 vibrates due to abnormal interference such as external impact and triggers a changing magnetic field signal, the processing unit 330 can effectively eliminate the interference information, so that the battery 310 will not heat the atomization component 100 to atomize the aerosol to generate the matrix. Therefore, only when the changing magnetic field signal is a normal suction signal can the processing unit 330 react by controlling the battery 310 to heat the atomization component 100. When the changing magnetic field signal is caused by other external factors such as non-inhalation airflow, the processing unit 330 will not react by controlling the battery 310 to heat the atomization component 100. In fact, refer to Fig. 9 The sensing unit 320 senses the signal generated by abnormal interference such as external impact as an irregular signal, see Fig.10 The sensing unit 320 senses that the signal generated by the suction airflow is a regular signal. Therefore, the processing unit 330 can easily determine whether the signal is generated by the suction airflow by analyzing whether the signal presents a certain regularity.

[0039] In some embodiments, the power supply 300 further includes a posture sensor, which is disposed on the housing. The posture sensor is used to sense the changing magnetic field signal generated by the movement of the magnetic component 200 caused by abnormal interference such as external vibration. The posture sensor does not transmit the changing magnetic field signal to the processing unit 330 for analysis and filtering, so as to prevent the changing magnetic field signal from causing the battery 310 to heat the atomization component 100. This can be understood as the posture sensor replacing the filtering function of the processing unit 330 for interference information, thereby improving the reaction speed of the processing unit 330. At the same time, the posture sensor can also sense the changing magnetic field signal from the outside world, which is not caused by the movement of the magnetic component 200. Similarly, the posture sensor will also prevent the changing magnetic field signal from being transmitted to the processing unit 330.

[0040] When the magnetic component 200 is disposed inside the air flow channel 110 of the atomizer component 100, the magnetic component 200 can fully utilize the space of the existing air flow channel 110 without occupying the space outside the air flow channel 110, so that the structure of the entire electronic atomizer device 10 is more compact. At the same time, the power supply 300 receives the changing magnetic field signal generated by the movement of the magnetic component 200, and can quickly judge the changing magnetic field signal and control the heating of the atomizer component 100 accordingly, thereby improving the sensitivity of the electronic atomizer device 10 when starting.

[0041] See also Figures 1 to 4 In some embodiments, the magnetic assembly 200 includes two magnetic units. When suction is performed from the nozzle opening 112, the suction airflow entering the airflow channel 110 from the air inlet hole 121 will push the two magnetic units to slide relative to each other, thereby changing the distance between the two magnetic units to produce a change in magnetic field strength.

[0042] Specifically, the two magnetic units are respectively referred to as a fixed magnetic unit 210 and a sliding magnetic unit 220 . The fixed magnetic unit 210 is fixed at a position away from the nozzle opening 112 . The sliding magnetic unit 220 is slidably disposed in the air flow channel 110, and the sliding magnetic unit 220 is located above the fixed magnetic unit 210. When suction is performed from the suction nozzle 112, a certain vacuum degree will be formed in the space above the sliding magnetic unit 220 of the air flow channel 110. Since the space below the sliding magnetic unit 220 of the air flow channel 110 is connected to the outside through the air inlet 121, there is an air pressure difference between the upper and lower sides of the sliding magnetic unit 220. Finally, under the push of the suction airflow moving from bottom to top in the air flow channel 110, the sliding magnetic unit 220 moves toward the suction nozzle 112 and away from the fixed magnetic unit 210 (i.e., moves upward), that is, the distance between the fixed magnetic unit 210 and the sliding magnetic unit 220 changes. In the process of increasing the distance, the magnetic field strength of the entire magnetic component 200 at the position where the sensing unit 320 is located also changes. At this time, the sensing unit 320 will sense the changing magnetic field signal, so that the processing unit 330 analyzes the changing magnetic field signal to control the battery 310 to heat the atomizer component 100. Of course, when the suction stops, under the action of gravity and magnetic attraction, the sliding magnetic unit 220 moves toward the fixed magnetic unit 210 and away from the nozzle opening 112 (i.e., moves downward), and the distance between the fixed magnetic unit 210 and the sliding magnetic unit 220 decreases. In the process of reducing the distance, the sensing unit 320 can also sense the changing magnetic field signal of its own position. However, since the processing unit 330 has a filtering function, the processing unit 330 can accurately determine that the changing magnetic field signal is not caused by the suction airflow pushing the magnetic component 200 to move, so the processing unit 330 will not control the battery 310 to heat the atomization component 100.

[0043] The electronic atomization device 10 further includes a first protrusion 141 and a second protrusion 142. The shapes of the first protrusion 141 and the second protrusion 142 can be substantially the same. When the airflow channel 110 is cylindrical, the first protrusion 141 and the second protrusion 142 are both annular. The edges of the first protrusion 141 and the second protrusion 142 are connected to the inner wall of the airflow channel 110. The first protrusion 141 is arranged near the mouthpiece 112. The first protrusion 141 is provided with a first communication hole 141a. The first communication hole 141a can allow airflow to pass through, so as to prevent the first protrusion 141 from blocking the airflow channel 110. The second protrusion 142 is arranged near the fixed magnetic unit 210. Similarly, the second protrusion 142 is provided with a second communication hole 142a. The second communication hole 142a can allow airflow to pass through, so as to prevent the second protrusion 142 from blocking the airflow channel 110. The second protrusion 142 is located between the first protrusion 141 and the fixed magnetic unit 210. The first protrusion 141, the sliding magnetic unit 220, the second protrusion 142 and the fixed magnetic unit 210 are arranged in sequence from top to bottom along the air flow channel 110. Figure 3 When suction is performed from the nozzle opening 112, the sliding magnetic unit 220 moves upward until it contacts the first protrusion 141, and the first protrusion 141 limits the maximum distance of the sliding magnetic unit 220 moving toward the nozzle opening 112. Figure 2 When the suction stops, the sliding magnetic unit 220 moves downward until it contacts the second protrusion 142, and the second protrusion 142 limits the maximum distance that the sliding magnetic unit 220 can move away from the nozzle 112. At this time, due to the isolation effect of the second protrusion 142, there is no direct contact relationship between the sliding magnetic unit 220 and the fixed magnetic unit 210. During suction, the sliding magnetic unit 220 is more likely to get rid of the attraction of the fixed magnetic unit 210 and move upward. Therefore, the first protrusion 141 and the second protrusion 142 play a good role in limiting the travel of the sliding magnetic unit 220. Of course, the first protrusion 141, the sliding magnetic unit 220, the fixed magnetic unit 210 and the second protrusion 142 can be arranged in sequence from top to bottom along the air flow channel 110, and the second protrusion 142 plays a reinforcing role in the fixation of the fixed magnetic unit 210, and the second protrusion 142 can even be omitted. In other embodiments, each magnetic unit in the magnetic assembly 200 is slidable; the first protrusion 141 and the second protrusion 142 can also be replaced by grooves opened on the inner wall of the air flow channel 110, and the upper and lower side walls of the groove can limit the stroke of the sliding magnetic unit 220.

[0044] See also Figures 2 to 4It is worth mentioning that both the first connecting hole 141a and the second connecting hole 142a can be circular, and at the same time, the sliding magnetic unit 220 and the fixed magnetic unit 210 can be bar-shaped permanent magnets or electromagnetic solenoids. Since the bar-shaped permanent magnets or electromagnetic solenoids are both long strips, when the sliding magnetic unit 220 abuts against the first protrusion 141, the long sliding magnetic unit 220 cannot block the entire circular first connecting hole 141a, so that the airflow can flow from the unblocked part of the first connecting hole 141a, ensuring that the user can smoke. Similarly, the long fixed magnetic unit 210 cannot block the entire circular second connecting hole 142a.

[0045] See also Figure 5 On the basis of other conditions in the above embodiment remaining unchanged, the fixed magnetic unit 210 can be removed so that the magnetic assembly 200 includes only one sliding magnetic unit 220. At this time, the sliding magnetic unit 220 slides between the first protrusion 141 and the second protrusion 142. The first protrusion 141 and the second protrusion 142 limit the maximum distance of the sliding magnetic unit 220 moving toward or away from the nozzle opening 112, that is, limit the maximum stroke of the sliding magnetic unit 220 moving up and down. When suction is performed from the nozzle opening 112, the sliding magnetic unit 220 moves upward toward the nozzle opening 112. During the movement, since the distance between the sliding magnetic unit 220 and the induction unit 320 changes, the magnetic field strength of the sliding magnetic unit 220 at the position of the induction unit 320 also changes. Of course, the magnetic component 200 can also include an elastomer 221, which can be a spring or a diaphragm, etc. One end of the elastomer 221 is fixed to the second protrusion 142, and the other end of the elastomer 221 is fixed to the sliding magnetic unit 220. When suction is performed from the nozzle opening 112, the sliding magnetic unit 220 overcomes the elastic force of the elastomer 221 and moves upward. When suction is stopped, the elastomer 221 can provide a restoring force, so that the sliding magnetic unit 220 moves quickly to a position abutting against the second protrusion 142.

[0046] See also Figure 1 , Figure 6 and Figure 7 In some embodiments, the magnetic assembly 200 includes two magnetic units. When suction is performed from the nozzle opening 112, the suction airflow entering the airflow channel 110 from the air inlet 121 will push the two magnetic units to rotate relative to each other, thereby changing the distance between the two magnetic units to produce a change in magnetic field strength.

[0047] Specifically, the two magnetic units are respectively recorded as a fixed magnetic unit 230 and a rotating magnetic unit 240, and the fixed magnetic unit 230 is fixed at a position close to the suction nozzle 112. The rotating magnetic unit 240 is rotatably set at a position away from the suction nozzle 112, and the rotating magnetic unit 240 can be set relative to the air inlet 121. When suction is performed from the suction nozzle 112, under the action of the vacuum force, the suction airflow entering the air flow channel 110 from the air inlet 121 pushes the rotating magnetic unit 240. During the rotation of the rotating magnetic unit 240, the magnetic field strength of the entire magnetic assembly 200 at the position where the induction unit 320 is located changes. The fixed magnetic unit 230 and the rotating magnetic unit 240 can both be bar permanent magnets or electromagnetic solenoids; of course, the fixed magnetic unit 230 uses a bar permanent magnet or an electromagnetic solenoid, and the rotating magnetic unit 240 uses a flat permanent magnet. When the airflow channel 110 is cylindrical, the rotating magnetic unit 240 rotates around the rotating shaft 241, and the rotating shaft 241 is parallel to or coincides with the central axis of the airflow channel 110, that is, the rotating shaft 241 is arranged vertically; of course, the rotating shaft 241 can also be perpendicular to the central axis of the airflow channel 110, that is, the rotating shaft 241 is arranged horizontally. In other embodiments, each magnetic unit in the magnetic assembly 200 can rotate. The magnetic assembly 200 can also include only one rotating rotating magnetic unit 240.

[0048] See also Fig.11 The present invention also provides an electronic atomization device 10a of another embodiment. The main difference between the electronic atomization device 10a of the other embodiment and the electronic atomization device 10 of the above embodiment is that the airflow channel 110a is partially opened on the power supply 300a, and the other part of the airflow channel 110a is opened on the atomization component 100 to communicate with the nozzle 112. The magnetic component 200a is located in the airflow channel 110 opened on the power supply 300a.

[0049] Specifically, the electronic atomization device 10a of another embodiment includes a power supply 300a and an atomizer 101a, the atomizer 101a includes an atomization assembly 100a, and a nozzle 112 is provided on the atomization assembly 100a. The power supply 300a includes a battery 310a, a sensing unit 320a, a processing unit 330a, a magnetic assembly 200a and a shell. The battery 310a, the sensing unit 320a and the processing unit 330a are all accommodated in the shell, and the battery 310a and the sensing unit 320a are both electrically connected to the processing unit 330a, and the processing unit 330a is arranged on the shell, and the sensing unit 320a can be arranged on the shell or the atomization assembly 100a. An air flow channel 110a is provided on the battery 310a, and the air flow channel 110a on the battery 310a is connected to the suction nozzle 112 on the atomizer 101a. The magnetic component 200a is located in the air flow channel 110a of the battery 310a and can move relative to the battery 310a. The structure of the magnetic component 200a can be the same as that of the magnetic component 200 in the electronic atomization device 10 of the above-mentioned embodiment.

[0050] When suction is drawn from the nozzle 112, the magnetic component 200a moves due to the pressure change in the airflow channel 110a. The sensing unit 320a receives the changing magnetic field signal generated by the movement of the magnetic component 200a and transmits it to the processing unit 330a. The processing unit 330a determines the changing magnetic field signal and controls the battery 310a to heat the atomizer 101a accordingly.

[0051] For other similarities of the electronic atomization device 10a of this other embodiment, please refer to the relevant description of the electronic atomization device 10 of the previous embodiment, which will not be repeated here.

[0052] The present invention also provides an atomizer 101, which is used to be connected to a power source 300. The atomizer 101 includes an atomizer assembly 100 and a magnetic assembly 200. The atomizer assembly 100 is provided with an air flow channel 110 and a suction nozzle 112 connecting the outside and the air flow channel 110. The magnetic assembly 200 can move relative to the air flow channel 110, and the magnetic assembly 200 can be located inside the air flow channel 110. The power source 300 includes a battery 310 and a processing unit 330. When suction is drawn from the suction nozzle 112, the magnetic assembly 200 moves due to the change in air pressure in the air flow channel 110. The processing unit 330 determines the change in magnetic field signal generated by the movement of the magnetic assembly 200 and controls the heating of the atomizer assembly 100 accordingly.

[0053] In some embodiments, the atomizer 101 may further include a sensing unit 320 , which is disposed on the atomizer assembly 100 , and receives a changing magnetic field signal generated by the movement of the magnetic assembly 200 , and transmits the changing magnetic field signal to the processing unit 330 .

[0054] The present invention also provides a power supply 300 of an electronic atomization device 10, which includes a magnetic component 200, a sensing unit 320, and an atomizer 101 with a nozzle 112. The power supply 300 includes a battery 310 and a processing unit 330, the processing unit 330 is arranged on the housing of the power supply 300, and the sensing unit 320 and the processing unit 330 are both electrically connected to the battery 310. When suction is drawn from the nozzle 112, the sensing unit 320 receives the changing magnetic field signal generated by the magnetic component 200 and transmits the changing magnetic field signal to the processing unit 330, and the processing unit 330 judges the changing magnetic field signal and controls the heating of the atomizer 101 by the battery 310 accordingly.

[0055] In some embodiments, the magnetic component 200 on the electronic atomization device 10 is a component of the power supply 300, that is, the power supply 300 also includes the magnetic component 200, and an air flow channel 110 connected to the nozzle opening 112 is opened on the battery 310. The magnetic component 200 can be located in the air flow channel 110, and the magnetic component 200 can move relative to the air flow channel 110. When suction is drawn from the nozzle opening 112, the magnetic component 200 moves due to the change in air pressure in the air flow channel 110, and the magnetic component 200 generates a changing magnetic field signal due to the movement.

[0056] In some embodiments, the sensing unit 320 on the electronic atomization device 10 is also a component of the power supply 300 , that is, the power supply 300 may also include the sensing unit 320 , and the sensing unit 320 is disposed on the housing of the power supply 300 .

[0057] The present invention also provides a control method of the electronic atomization device 10, which is used to control the electronic atomization device 10 in the above embodiment and mainly includes the following steps:

[0058] The magnetic component 200 of the electronic atomization device 10 moves relative to the airflow channel 110 of the electronic atomization device 10 by suction, and the magnetic component 200 generates a changing magnetic field signal due to the movement;

[0059] receiving the changing magnetic field signal; and

[0060] The changing magnetic field signal is judged and the heating of the electronic atomization device 10 is controlled accordingly.

[0061] In some embodiments, the movement of the magnetic component 200 relative to the airflow channel 110 can be in the form of sliding, rotating, and a combination of sliding and rotating. The sensing unit 320 such as a magnetic sensor receives the sensing change magnetic field signal, and the change magnetic field signal includes a change in the direction of the magnetic field, a change in the magnitude of the magnetic field, or a simultaneous change in the direction and magnitude of the magnetic field. The sensing unit 320 transmits the change magnetic field signal to the processing unit 330 such as a single-chip microcomputer, and the processing unit 330 analyzes the change magnetic field signal. If it is determined that the change magnetic field signal is caused by a normal suction airflow, the battery 310 is controlled to heat the atomizer component 100; if it is determined that the change magnetic field signal is caused by an external impact or an external magnetic field, the battery 310 is controlled not to heat the atomizer component 100. Of course, the attitude sensor can also be directly used to sense the change magnetic field signal caused by an abnormal suction airflow such as an external impact or an external magnetic field, and the change magnetic field signal caused by the abnormal suction airflow is stopped from being transmitted to the processing unit 330, so that the processing unit 330 cannot receive the change magnetic field signal caused by the abnormal suction airflow, that is, the attitude sensor has a filtering function to eliminate interference information.

[0062] The control method can improve the starting sensitivity while making the electronic atomization device compact in structure.
