Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, and in particular to an atomization main body and an electronic atomization device. BACKGROUND

[0002] Tobacco products, such as cigarettes, cigars, and the like, burn tobacco during use to produce tobacco smoke. Attempts have been made to provide alternatives to these burning tobacco products by creating products that release compounds without burning.

[0003] Examples of such products are heating devices that release compounds by heating, rather than burning, a material. For example, the material can be tobacco or other non-tobacco products, which can or can not contain nicotine. As another example, there are aerosol provision devices, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to cause it to vaporize, thereby producing an inhalable aerosol. The liquid can contain nicotine and / or flavorings and / or an aerosol generating substance (e.g., glycerol).

The receiving cavity 11 is open from a front side 150 to a rear side 160. In embodiments, the receiving cavity 11 is open at the front side 150 and the rear side 160.

[0140] Pins 131 and 141 are used to connect the second body 200 with the main housing 10 of the first body 100. In embodiments, the pins 131 and 141 are arranged along a width direction of the first body 100. Further, the pins 131 and 141 are arranged in alignment along the width direction.

[0208] For example, in specific embodiments, the indicating element 12 is a magnet 12 for generating a magnetic field, and the sensing element 2821 is a Hall sensor 2821 for sensing the magnetic field strength or the presence of the magnetic field generated by the magnet 12 close to the Hall sensor 2821. When the first end 210 of the second body 200 is towards the proximal end 110, the distance between the Hall sensor 2821 and the magnet 12 is greater than when the first end 210 of the second body 200 is towards the distal end 120. Then, for example, when the user operates the first end 210 of the second body 200 towards the proximal end 110, the Hall sensor 2821 can sense the presence of the magnetic field generated by the magnet 12 or can sense a first magnetic field strength; and when the user operates the second end 210 of the second body 200 towards the proximal end 110, the Hall sensor 2821 cannot sense the presence of the magnetic field generated by the magnet 12 or can sense a second magnetic field strength smaller than the first magnetic field strength. Then, according to the sensing result of the Hall sensor 2821, the first circuit board 282 can determine whether the first end 210 of the second body 200 is towards the proximal end 110 or the second end 220 is towards the proximal end 110.

[0209] In embodiments, there is no magnetic field in the second body 200 that can be sensed by the Hall sensor 2821, so that the Hall sensor 2821 can only sense the presence of the magnetic field from the magnet 12 of the first body 100 close to the Hall sensor 2821.

[0210] In embodiments, the indicating element 12, e.g. the magnet 12, is arranged on the main housing 10 of the first body 100; more specifically, the indicating element 12, e.g. the magnet 12, is arranged on the inner side surface of the accommodation cavity 11 close to the second side 140 and / or the first side 130. In embodiments, the distance between the indicating element 12, e.g. the magnet 12, and the inner side surface of the accommodation cavity 11 towards the proximal end 110 is less than the distance between the indicating element 12, e.g. the magnet 12, and the inner side surface of the accommodation cavity 11 towards the distal end 120. Alternatively, the indicating element 12, e.g. the magnet 12, is closer to the proximal end 110 than the pin 131 and / or the pin 141. In embodiments, the sensing element 2821, e.g. the Hall sensor 2821, is arranged between the first circuit board 282 and the second circuit board 283 of the second body 200; and the sensing element 2821, e.g. the Hall sensor 2821, is located between the electric core 281 and the second side 240.

[0213] The electric core 281 is arranged between the first circuit board 282 and the second circuit board 283; the electric core 281 is electrically connected to the first circuit board 282 and the second circuit board 283 simultaneously.

[0214] In embodiments, the first circuit board 282 and the second circuit board 283 are arranged perpendicular to the longitudinal direction of the second body 200. In use, the electric core 281 is used to supply power to the atomizer, e.g. the first atomizer and / or the second atomizer; the first circuit board 282 controls the electric core 281 to supply power to the first atomizer; the second circuit board 283 controls the electric core 281 to supply power to the second atomizer.

[0215] In embodiments, the sensing element 2821 is electrically connected to the first circuit board 282; and the first end 210 of the second body 200 is determined to be towards the proximal end 110 or the distal end 120 according to the sensing result of the sensing element 2821 by the first circuit board 282.

[0217] The second detection mechanism is used to detect whether the mouthpiece 20 is located at the first position or the second position when the second body 200 is rotated to coincide with the longitudinal direction of the first body 100.

[0218] In some embodiments, the first conductive element 24 is arranged on the mouthpiece 20; the second detecting mechanism determines whether the mouthpiece 20 is in the first position or the second position by detecting the position of the first conductive element 24. In embodiments, the first conductive element 24 is arranged on the pin shaft 23. After assembly, the first conductive element 24 is at least partially inserted into or exposed from the accommodating cavity 11.

[0219] In some embodiments, the first conductive element 24 and / or the pin shaft 23 is offset from the longitudinal central axis of the main housing 10. Specifically, in embodiments, the first conductive element 24 and / or the pin shaft 23 is offset from the longitudinal central axis of the main housing 10 by a distance of about 1-2 mm.

[0221] spaced second conductive elements 214 and 215. The second conductive elements 214 and 215 are at least partially exposed from the first end 210. The second conductive elements 214 and 215 are also arranged offset from the longitudinal central axis of the second main body 200.

In embodiments, the second conductive elements 214 and 215 are respectively connected to the first circuit board 282 by wires or the like.

[0222] According to Figure 26 , when the mouthpiece 21 is rotated to the second position, the first conductive element 24 is inserted between the spaced second conductive elements 214 and 215 and simultaneously contacts the second conductive elements 214 and 215, so that the first conductive element 24 conducts the spaced second conductive elements 214 and 215. According to Figure 27 , when the mouthpiece 21 is rotated to the first position, the first conductive element 24 is relatively rotated to be closer to the front side 250, so as to simultaneously separate from the second conductive elements 214 and 215; at this time, the spaced second conductive elements 214 and 215 are electrically disconnected. In embodiments, the first circuit board 282 determines whether the mouthpiece 21 is in the first position or the second position by detecting whether the second conductive elements 214 and 215 are connected or disconnected.

[0223] In some embodiments, the first circuit board 282 determines whether the second electrically conductive element 214 and the second electrically conductive element 215 are in an electrically conductive loop or in an open circuit, and thus determines whether the second electrically conductive element 214 and the second electrically conductive element 215 are in an electrically conductive state or in an electrically non-conductive state.

In some embodiments, the second electrically conductive element 224 and the second electrically conductive element 225 are respectively connected to the second circuit board 283 by wires or the like. When the first end 210 of the second body 200 is turned to face the distal end 120 and the second end 220 faces the proximal end 110, the second circuit board 283 determines whether the second electrically conductive element 224 and the second electrically conductive element 225 are in an electrically conductive state or in an electrically non-conductive state by detecting whether the second electrically conductive element 224 and the second electrically conductive element 225 are in an electrically conductive loop or in an open circuit.

[0226] In some embodiments, the first electrically conductive element 24, the second electrically conductive element 214 and the second electrically conductive element 215, and the second electrically conductive element 224 and the second electrically conductive element 225 are made of electrically conductive metal or alloy materials.

[0255] In embodiments, the structure and arrangement of the second airflow channel are basically the same as those of the first airflow channel, and will not be described again.

[0256] In embodiments, the first airflow channel and the second airflow channel are isolated from each other. Specifically, in embodiments, the first airflow channel is arranged between the first circuit board 282 and the first end 210; and the second airflow channel is arranged between the second circuit board 283 and the second end 220.

[0257] ​​In this embodiment, the first airflow channel and the second airflow channel avoid the battery cell 281.

Correspondingly, a second airflow channel is at least partially formed between the second support 290 and the third housing 231.

[0262] according to Figure 24 , Figures 1 to 6 As shown, the second body 200 also includes:

[0263] A first airflow sensor 2823, such as a microphone sensor or MEMS sensor, is used to sense the airflow passing through a first airflow channel when the user inhales. In an embodiment, the first airflow sensor 2823 is mounted or disposed on the surface of a first circuit board 282 facing the first end 210. According to... Figures 15 to 27 As shown, the first airflow sensor 2823 is connected to the air cavity 2360; specifically, the first airflow sensor 2823 is connected to the port of the air cavity 2360 facing the first circuit board 282. In use, the first airflow sensor 2823, through its connection to the air cavity 2360, senses changes in airflow through the first airflow channel when the user inhales. The first circuit board 282 then controls the battery cell 281 to provide power to at least one first atomizer based on the sensing result of the first airflow sensor 2823, so that at least one first atomizer generates aerosol.

[0264] according to Figure 24 , Figures 1 to 6 As shown, the second body 200 also includes:

[0265] A second airflow sensor 2831, such as a microphone sensor or MEMS sensor, is used to sense the airflow passing through the second airflow channel when the user inhales. In an embodiment, the second airflow sensor 2831 is mounted or arranged on the surface of the second circuit board 283 facing the second end 220.

In use, in turn, the second airflow sensor 2831 senses a change in airflow through the second airflow passage upon user puffing by virtue of being in communication with the air cavity 2370. In turn, the second circuit board 283 controls the power supply from the power supply 281 to the at least one second atomizer based on the sensing result of the second airflow sensor 2831 to cause the at least one second atomizer to generate aerosol.

[0266] In embodiments, the mouthpiece is selectively changeable between the first position and the second position by a user rotating the mouthpiece 20 in use, thereby allowing only the first airflow passage to flow through the two first atomizers or the second atomizer. The second body 200 is configured to:

[0267] The control circuit 281 only supplies power to the first atomizer or the second atomizer in air communication with the air outlet 21 to generate aerosol when the mouthpiece 20 is in the first position or the second position.

[0268] Specifically, for example, the control circuit on the first circuit board 282 is configured to:

[0269] The control circuit 281 only supplies power to the first atomizer 520 and the first atomizer 530 in air communication with the air outlet 21 when the mouthpiece 20 is in the first position, thereby causing the first atomizer 520 and the first atomizer 530 to generate aerosol and output to the air outlet 21; and the control circuit 281 only supplies power to the first atomizer 510 and the first atomizer 540 in air communication with the air outlet 21 when the mouthpiece 20 is in the second position, thereby causing the first atomizer 510 and the first atomizer 540 to generate aerosol and output to the air outlet 21. Specifically, for another example, in some embodiments, the control circuit on the first circuit board 282 is configured to control the power supply 281 to not supply power to all the first atomizers at the same time.

[0270] Specifically, for another example, the control circuit on the second circuit board 283 is configured to:

[0271] When the mouthpiece 20 is in the first position, the control electric chip 281 only provides power to the second atomizers 620 and 630 in air communication with the air outlet 21, thereby causing the second atomizers 620 and 630 to generate aerosol and then output to the air outlet 21; and when the mouthpiece 20 is in the second position, the control electric chip 281 only provides power to the second atomizers 610 and 640 in air communication with the air outlet 21, thereby causing the second atomizers 610 and 640 to generate aerosol and then output to the air outlet 21. Specifically, for example, in some embodiments, the control circuit on the second circuit board 283 is configured to control the electric chip 281 to not simultaneously provide power to all the second atomizers.

[0272] In embodiments, based on the user pressing the second body 200 to flip inside the first body 100 in use, the second body 200 is configured to:

[0273] When the first end 210 is inside the accommodating cavity 11 of the first body 100 towards the proximal end 110, only the electric chip 281 is allowed to provide power to the first atomizers, while the second atomizers are prevented from being powered; and when the first end 210 is inside the accommodating cavity 11 of the first body 100 towards the distal end 120, only the electric chip 281 is allowed to provide power to the second atomizers, while the first atomizers are prevented from being powered.

[0274] Specifically, for example, in some embodiments, the second body 200 is configured such that the first circuit board 282 controls the electric chip 281 to provide power to the first atomizers and the second circuit board 283 controls the electric chip 281 to provide power to the second atomizers cannot be performed simultaneously. Or the second body 200 is configured such that the first circuit board 282 controls the electric chip 281 to provide power to the first atomizers and the second circuit board 283 controls the electric chip 281 to provide power to the second atomizers cannot be performed simultaneously.

[0275] Specifically, in some embodiments, the first circuit board 282 and the second circuit board 283 are electrically connected. Then, the second circuit board 283 can be configured to not respond to the sensing result of the second airflow sensor 2831 according to the detection or determination of the first circuit board 282 when the first end 210 is facing the proximal end 110; and the second circuit board 283 can be configured to respond to the sensing result of the second airflow sensor 2831 according to the detection or determination of the first circuit board 282 when the first end 210 is facing the distal end 120. In this way, it is safer to control the power supply to the corresponding atomizer according to the orientation of the first end 210 and the sensed airflow. For example, when the first circuit board 282 detects that the first end 210 is facing the distal end 120 and at the same time the second airflow sensor 2831 senses that there is a suction airflow, it indicates that the flipping direction of the second body 200 is logically consistent with the suction airflow, at this time the second circuit board 283 can be allowed to respond to the sensing of the second airflow sensor 2831 to control the power supply of the second atomizer by the battery 281. For another example, when the first circuit board 282 detects that the first end 210 is facing the proximal end 110, but at the same time the second airflow sensor 2831 senses that there is a suction airflow, the flipping direction of the second body 200 is logically inconsistent with the suction airflow, indicating that the second airflow sensor 2831 may be misfired, etc., at this time the second circuit board 283 can not respond to the sensing result of the second airflow sensor 2831.

[0276] According to ​ 、 ​ As shown in FIG. 2, the second body 200 further comprises:

[0277] A button 233 for user operation to generate an input signal representing a user pressing action. The button 233 is exposed on the front side 250 for user pressing operation. The button 233 is electrically connected to the second circuit board 283.

[0278] In some embodiments, the user operation of the button 233 locks or unlocks the second body 200. The second circuit board 283 can control the second body 200 to switch between a locked state and an unlocked state according to the user pressing operation of the button 233. When the second body 200 is in the locked state, the battery 281 is prevented from supplying power to any atomizer, thereby preventing the second body 200 from generating aerosol; this is beneficial for preventing the output of aerosol to users, especially minors, i.e., the so-called "child lock" function. When the second body 200 is in the unlocked state, the battery 281 is allowed to supply power to the atomizer.

[0279] Or in some embodiments, the second circuit board 283 can control to increase or decrease or change the power provided by the battery cell 281 to the atomizer according to the operation of the user pressing the button 233. It is advantageous to meet the user's control of larger or smaller aerosol suction dose in use.

[0280] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification, and further, those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
