Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1 and fig. 2, an electronic atomizer 10 according to an embodiment of the present invention includes an atomizer 101 and a power source 300, where the atomizer 101 includes an atomizing assembly 100 and a magnetic assembly 200. The electronic atomization device 10 is provided with an air flow channel 110, and the air flow channel 110 is a channel through which outside air enters the inside of the electronic atomization device 10 from at least one inlet and reaches an outlet for a user to suck. The electronic atomizer 10 may include one or more airflow channels 110, for example, the airflow channels 110 are all disposed on the atomizer assembly 100, the magnetic assembly 200 may be located inside the airflow channels 110, or the magnetic assembly 200 may be located outside the airflow channels 110 and near the ports of the airflow channels 110, and the power source 300 is disposed opposite to the atomizer assembly 100.

In some embodiments, the atomization assembly 100 is used to store an aerosol-generating substrate, while being able to heat the aerosol-generating substrate for atomization. The aerosol formed by atomisation of the aerosol-generating substrate is able to flow within the airflow passage 110, the upper end of the airflow passage 110 forming a mouthpiece 112 to the atomising assembly 100, the mouthpiece 112 being in communication with the environment.

The atomizing assembly 100 further has an air inlet hole 121, for example, the air inlet hole 121 is disposed on a side surface or a bottom surface of the atomizing assembly 100, and the air inlet hole 121 is disposed away from the nozzle opening 112. The air intake holes 121 communicate the air flow passage 110 with the outside. When suction is applied from the nozzle opening 112, ambient air enters the airflow channel 110 from the air inlet apertures 121 to form a suction airflow, which passes through the airflow channel 110 to carry the atomized aerosol-generating substrate into the user's mouth via the nozzle opening 112, thereby effecting the user's suction of the aerosol.

The power supply 300 is connected to the atomizing 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 can be installed on the atomizing assembly 100, and the sensing unit 320 and the processing unit 300 are both electrically connected to the battery 310. When the battery 310 heats the atomizing assembly 100, the atomizing assembly 100 atomizes the aerosol-generating substrate and the atomized aerosol passes through the nozzle 112 for inhalation by the user. When the battery 310 ceases to heat the atomizing assembly 100, the atomizing assembly 100 ceases to atomize the aerosol-generating substrate and the atomizing assembly 100 will not produce an aerosol for the user to draw. The sensing Unit 320 may be a magnetic sensor, the processing Unit 330 may be a single chip Microcomputer (MCU), the sensing Unit 320 is configured to sense a changing magnetic field signal (the changing magnetic field signal includes a change in a magnetic field direction, a change in a magnetic field magnitude, and a change in both the magnetic field direction and the magnetic field magnitude), and transmit the changing magnetic field signal to the processing Unit 330, the processing Unit 330 is configured to analyze and determine the changing magnetic field signal, and the processing Unit 330 may control the battery 310 to heat the atomizing assembly 100, so as to achieve a purpose of atomizing the aerosol generating substrate.

When the magnetic assembly 200 is located in the airflow channel 110, the magnetic assembly 200 may be located close to the power source 300, when a user sucks on the nozzle opening 112, the magnetic assembly 200 can move relative to the atomizing assembly 100 under the pushing action of the sucking airflow, and the sensing unit 320 receives a varying magnetic field signal generated by the movement of the magnetic assembly 200. In some embodiments, the sensing unit 320 is disposed at a location where the battery 310 is close to the atomization assembly 100, for example, the sensing unit 320 is disposed below the atomization assembly 100. This facilitates the sensing unit 320 to accurately and rapidly sense the varying magnetic field signal generated by the movement of the magnetic assembly 200, and improves the sensitivity of the sensing unit 320 and the response speed of the whole electronic device to the user's suction.

The processing unit 330 has a good filtering function, and in the process of analyzing the varying magnetic field signal, the processing unit 330 can accurately determine whether the varying magnetic field signal is a normal suction signal generated by the user sucking the airflow to push the magnetic assembly 200 to move. For example, when the magnetic assembly 200 vibrates due to abnormal interference such as external impact to generate a varying magnetic field signal, the processing unit 330 can effectively remove the interference information, so that the battery 310 does not heat the atomizing assembly 100 to atomize the aerosol-generating substrate. Therefore, the processing unit 330 can control the battery 310 to perform heating reaction on the atomizing assembly 100 only when the varying magnetic field signal is the normal pumping signal, and the processing unit 330 can not control the battery 310 to perform heating reaction on the atomizing assembly 100 when the varying magnetic field signal is caused by other external factors such as non-pumping airflow. In fact, referring to fig. 9, the sensing unit 320 senses the signal generated by the abnormal disturbance such as the external impact as an irregular signal, and referring to fig. 10, the sensing unit 320 senses the signal generated by the suction airflow as a regular signal, and therefore, the processing unit 330 can easily determine whether the signal is generated by the suction airflow by analyzing whether the signal shows a certain rule.

In some embodiments, the power supply 300 further includes an attitude sensor disposed on the housing. The attitude sensor is used for sensing a variable magnetic field signal generated by the movement of the magnetic assembly 200 caused by abnormal interference such as external vibration, and the attitude sensor does not transmit the variable magnetic field signal to the processing unit 330 for analysis and filtering, so that the atomizing assembly 100 is prevented from being heated by the battery 310 due to the variable magnetic field signal, and thus the attitude sensor can be understood to replace the filtering function of the processing unit 330 on interference information, and the reaction speed of the processing unit 330 is improved. At the same time, the attitude sensor can also sense the changing magnetic field signal from the outside, which is not caused by the movement of the magnetic assembly 200, and similarly, the attitude sensor will prevent the changing magnetic field signal from being transmitted to the processing unit 330.

When the magnetic assembly 200 is disposed inside the airflow channel 110 of the atomizing assembly 100, the magnetic assembly 200 can fully utilize the space of the existing airflow channel 110 without occupying the space outside the airflow channel 110, so that the whole electronic atomizing device 10 is more compact. Meanwhile, the power supply 300 receives the variable magnetic field signal generated by the movement of the magnetic assembly 200, and can quickly determine the variable magnetic field signal to control the heating of the atomizing assembly 100, thereby improving the starting sensitivity of the electronic atomizing device 10.

Referring also to fig. 1-4, in some embodiments, the magnetic assembly 200 includes two magnetic units, and when suction is applied from the nozzle opening 112, the suction airflow entering the airflow channel 110 from the air inlet hole 121 pushes the two magnetic units to slide relatively, thereby changing the distance between the two magnetic units to generate the magnetic field strength change.

Specifically, the two magnetic units are respectively referred to as a fixed magnetic unit 210 and a sliding magnetic unit 220, and the fixed magnetic unit 210 is fixed at a position away from the mouthpiece 112. The sliding magnetic unit 220 is slidably disposed in the air flow channel 110, the sliding magnetic unit 220 is located above the fixed magnetic unit 210, when suction is performed from the suction nozzle 112, a space above the sliding magnetic unit 220 of the air flow channel 110 will form a certain vacuum degree, since the space below the sliding magnetic unit 220 of the air flow channel 110 is communicated with the outside through the air inlet hole 121, air pressure difference exists between the upper side and the lower side of the sliding magnetic unit 220, finally, under the push of the suction air flow moving from bottom to top in the air flow channel 110, the sliding magnetic unit 220 moves towards the suction nozzle 112 and moves away from the fixed magnetic unit 210 (i.e. moves upwards), i.e. the distance between the fixed magnetic unit 210 and the sliding magnetic unit 220 changes, and in the process of increasing the distance, the magnetic field intensity of the whole magnetic assembly 200 at the position where the induction unit 320 is located also changes, at this time, the sensing unit 320 senses the varying magnetic field signal, so that the processing unit 330 analyzes the varying magnetic field signal to control the battery 310 to heat the atomizing assembly 100. Of course, when the suction is stopped, 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 112 (i.e. moves downward), the distance between the fixed magnetic unit 210 and the sliding magnetic unit 220 decreases, and during the decrease of the distance, the sensing unit 320 can also sense the changing magnetic field signal at its own position, but since the processing unit 330 has a filtering function, the processing unit 330 can accurately determine the changing magnetic field signal and is not caused by the movement of the magnetic assembly 200 pushed by the suction airflow, the processing unit 330 will not control the battery 310 to heat the atomizing assembly 100.

The electronic atomization device 10 further includes a first bump 141 and a second bump 142, the first bump 141 and the second bump 142 may have substantially the same shape, when the airflow channel 110 is cylindrical, the first bump 141 and the second bump 142 are both circular rings, edges of the first bump 141 and the second bump 142 are both connected to an inner wall of the airflow channel 110, the first bump 141 is disposed near the nozzle 112, the first bump 141 is provided with a first through hole 141a, the first through hole 141a can allow the airflow to pass through, and the first bump 141 is prevented from blocking the airflow channel 110. The second protrusion 142 is disposed close to the fixed magnetic unit 210, and similarly, the second protrusion 142 is provided with a second communication hole 142a, through which the air flow can pass, so as to prevent the second protrusion 142 from blocking the air flow channel 110. The second protrusion 142 is located between the first protrusion 141 and the fixed magnetic unit 210, and the first protrusion 141, the sliding magnetic unit 220, the second protrusion 142 and the fixed magnetic unit 210 are sequentially arranged from top to bottom along the airflow channel 110. Referring to fig. 3, when suction is performed from the nozzle opening 112, the sliding magnetic unit 220 moves upward until abutting against the first protrusion 141, and the first protrusion 141 limits the limit distance of the movement of the sliding magnetic unit 220 toward the nozzle opening 112. Referring to fig. 2, when the suction is stopped, the sliding magnetic unit 220 moves downward until it abuts against the second protrusion 142, and the second protrusion 142 limits the limit distance of the movement of the sliding magnetic unit 220 away from the nozzle opening 112. At this time, there is no direct contact relationship between the sliding magnetic unit 220 and the fixed magnetic unit 210 due to the isolation of the second protrusion 142, so that the sliding magnetic unit 220 is more easily moved upward free from the attraction force of the fixed magnetic unit 210 at the time of suction. Therefore, the first and

second protrusions

141 and 142 play a very good role in limiting the stroke 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 may be sequentially arranged from top to bottom along the airflow channel 110, the second protrusion 142 may enhance the fixing of the fixed magnetic unit 210, and the second protrusion 142 may even be omitted. In other embodiments, each magnet unit in the magnet assembly 200 is slidable; the first projection 141 and the second projection 142 may be replaced by a groove formed on the inner wall of the airflow passage 110, and the upper and lower sidewalls of the groove may limit the stroke of the sliding magnet unit 220.

Referring to fig. 2 to 4, it is worth mentioning that both the first and

second communication holes

141a and 142a may be circular, and the sliding magnetic unit 220 and the fixed magnetic unit 210 may be bar-shaped permanent magnets or electromagnetic solenoids. Because the bar permanent magnet or the electromagnetic solenoid is in a long strip shape, when the sliding magnetic unit 220 abuts against the first protrusion 141, the long sliding magnetic unit 220 cannot seal the whole circular first through hole 141a, so that the airflow can circulate from the part of the first through hole 141a which is not sealed, and the user can be ensured to suck the smoke. Similarly, the elongated fixed magnetic unit 210 cannot block the entire circular second communication hole 142 a.

Referring to fig. 5, on the basis of the above embodiment without changing other conditions, the fixed magnetic unit 210 may be eliminated, so that the magnetic assembly 200 includes only one sliding magnetic unit 220. At this time, the sliding magnetic unit 220 is located between the first protrusion 141 and the second protrusion 142 to slide, and the first protrusion 141 and the second protrusion 142 limit the limit distance of the sliding magnetic unit 220 moving towards or away from the nozzle opening 112, i.e. limit the limit 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, and during the movement, since the distance between the sliding magnetic unit 220 and the sensing unit 320 changes, the magnetic field intensity of the sliding magnetic unit 220 at the position of the sensing unit 320 also changes. Of course, it is also possible to make the magnetic assembly 200 include an elastic body 221, the elastic body 221 may be a spring or a diaphragm, etc., one end of the elastic body 221 is fixed on the second protrusion 142, the other end of the elastic body 221 is fixed on the sliding magnetic unit 220, when suction is performed from the suction nozzle 112, the sliding magnetic unit 220 moves upward against the elastic force of the elastic body 221, and when suction is stopped, the elastic body 221 may provide a restoring force, so that the sliding magnetic unit 220 moves rapidly to a position abutting against the second protrusion 142.

Referring to fig. 1, 6 and 7, in some embodiments, the magnetic assembly 200 includes two magnetic units, and when suction is applied from the nozzle opening 112, the suction airflow entering the airflow channel 110 from the air inlet hole 121 pushes the two magnetic units to rotate relatively, thereby changing the distance between the two magnetic units to generate the magnetic field strength change.

Specifically, the two magnetic units are respectively referred to 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 nozzle opening 112. The rotary magnetic unit 240 is rotatably disposed at a position far from the nozzle opening 112, the rotary magnetic unit 240 may be disposed opposite to the air inlet hole 121, when suction is performed from the nozzle opening 112, the suction air flow entering the air flow channel 110 from the air inlet hole 121 pushes the rotary magnetic unit 240 under the action of vacuum force, and during the rotation of the rotary magnetic unit 240, the magnetic field intensity of the whole magnetic assembly 200 at the position of the sensing unit 320 changes. The fixed magnetic unit 230 and the rotating magnetic unit 240 may be both bar-type permanent magnets or electromagnetic solenoids; of course, the fixed magnetic unit 230 employs a bar-shaped permanent magnet or an electromagnetic solenoid, and the rotating magnetic unit 240 employs a flat plate-shaped permanent magnet. In the case that the air flow passage 110 is cylindrical, the rotating magnetic unit 240 rotates around a rotating shaft 241, the rotating shaft 241 is parallel to or coincident with the central axis of the air flow passage 110, that is, the rotating shaft 241 is vertically disposed; of course, the rotation shaft 241 may be perpendicular to the central axis of the air flow channel 110, that is, the rotation shaft 241 may be transversely disposed. In other embodiments, each magnet unit in the magnet assembly 200 is rotatable. The magnet assembly 200 may also include only one rotating magnet unit 240.

The magnetic assembly 200a is positioned in the airflow passage 110 that opens in the power supply 300 a.

Specifically, the electronic atomizer 10a of the another embodiment includes a power source 300a and an atomizer 101a, the atomizer 101a includes an atomizing assembly 100a, and the atomizing assembly 100a has a nozzle 112.

When the air is sucked from the nozzle opening 112, the magnetic assembly 200a moves due to the pressure change in the air flow channel 110a, the sensing unit 320a receives the changing magnetic field signal generated due to the movement of the magnetic assembly 200a and transmits the signal to the processing unit 330a, and the processing unit 330a determines the changing magnetic field signal and controls the heating of the atomizer 101a by the battery 310a accordingly.
