Technical Field

These devices typically contain a liquid that is heated to vaporize it, thereby generating an inhalable aerosol. The liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol). Electronic nebulizing devices are known in which a user's suction is sensed by an air flow sensor and the vaporization of a liquid is controlled to generate an aerosol in accordance with the sensing of the air flow sensor.

In some implementations, the heating elements 30 are patterned conductive traces. In still other implementations, the heating element 30 is planar. In practice, the heating element 30 is a circuitous, serpentine, reciprocating, or meandering electrically conductive track.

As further shown in fig. 2, a sealing element 40 is also disposed within the housing 10; the sealing member 40 at least partially supports the aerosol output tube 11 and seals the reservoir 12. Then, when assembled, the reservoir 12 defined between the outer wall of the aerosol output tube 11 and the inner wall of the housing 10 is closed at the end near the proximal end 110; and the reservoir 12 is sealed at the end toward the distal end 120 by the sealing member 40.

For ease of assembly, the sealing element 40 is provided with an insertion portion 41 extending towards the proximal end 110 for insertion of the aerosol delivery tube 11. The sealing element 40 also defines an air passage 42 which hangs through the sealing element 40 in the longitudinal direction of the electronic atomising device for the entry of ambient air into the aerosol output tube 11 during inhalation. According to what is shown in fig. 2, the air channel 42 is at least partially surrounded by the plug part 41.

As further shown in fig. 2, the electronic atomizer 100 further includes:

the cell 140 is received and retained within the second housing 160 and is located between the sealing member 40 and the distal end 130. A cell 140 used to power the heating element 30; in the connection, the sealing element 40 is provided with a lead hole 43, and after the assembly, two ends of the heating element 30 are connected to the battery cell 140 through a lead passing through the lead hole 43, so that the heating element 30 is communicated with the battery cell 140 to realize power supply. And, when assembled, a gap or clearance is maintained between the cell 140 and the second housing 160 for air entering from the distal end 120 to enter the aerosol output tube 11 through the gap between the cell 140 and the second housing 160.

Of course, the electronic atomization device 100 is further provided with:

a circuit board (not shown) for controlling the power output from the cells 140 to the heating element 30.

On the suction intake air of the electronic atomization device 100, as further shown in fig. 1, a circumferential side surface of the second housing 160 near the distal end 120 is provided with a first air intake hole 121 extending along the circumferential direction, for allowing the outside air to enter into the electronic atomization device 100 and/or the housing during suction.

In the complete suction airflow path arrangement, as shown in fig. 1-3, the second housing 160 has a recessed slot 123 at the distal end 120; the first intake holes 121 are located on the peripheral side surface defining the concave groove 123; correspondingly, the inner bottom wall of the recess groove 123 of the second casing 160 is provided with a second air hole 122, and the second air hole 122 is communicated with the first air inlet hole 121. During the suction process, as shown by an arrow R2 in fig. 2 and 3, the external air enters the second casing 160 through the first air inlet hole 121 and the second air outlet hole 122 in sequence, flows to the air channel 42 of the sealing element 40 through the gap between the second casing 160 and the battery core 140, then passes through the air channel 42 and the aerosol output tube 11, and carries the aerosol to be output to the air inlet a.

As further shown in fig. 2, 4 and 5, the electronic atomizer 100 further includes:

an airflow sensor 150 for sensing airflow in the user's puff to determine the user's puff. The airflow sensor 150 is arranged to be located within the second housing 160; and an airflow sensor 150 is positioned between the cell 140 and the distal end 120. An airflow sensor 150, such as a microphone or differential pressure sensor, may sense airflow. Specifically, the airflow sensor 150 has a first side 151 and a second side 152 facing away from each other in a longitudinal direction of the electronic atomization device 100. When assembled, the first side 151 is disposed toward the cell 140, and the first side 151 is in airflow communication with the gap or gap between the cell 140 and the second casing 160, thereby enabling the sensing of airflow through the gap between the cell 140 and the second casing 160 during a user puff. The second side 152 is toward the distal end 120. The first side 151 and the second side 152 of the airflow sensor 150 are in airflow communication, for example as shown in fig. 2 and 4, the second side 152 being in airflow communication with the first side 151 of the airflow sensor 150 through the through hole 91 of the sealing member 90. When used for suction, the first side 151 faces directly towards and towards the suction nozzle, and the negative pressure drops more on the first side 151 than on the second side 152; the airflow sensor 150 determines a pumping action of the user and outputs a high level signal when a pressure difference between the first side 151 and the second side 152 is greater than a preset threshold value according to the suction airflow; further, the circuit board (not shown in the figure) controls the electrical core 140 to output power to the heating element 30 according to the sensing signal of the airflow sensor 150 to atomize the liquid to generate aerosol.

And according to the illustration, the airflow sensor 150 is disposed proximate the distal end 120; and airflow sensor 150 is located at distal end 120 and is disposed proximate to the air intake.

As further shown in fig. 2, 4 and 5, the airflow sensor 150 is generally wrapped and retained by the sealing member 90 in an assembly for stable detection by the airflow sensor 150, such as a microphone or differential pressure sensor. Specifically, in the implementation, the sealing member 90 has a cylindrical shape with a cavity inside, the airflow sensor 150 is wrapped and fitted inside the sealing member 90, and the sealing member 90 has a first end 910 and a second end 920 facing away from each other in the longitudinal direction of the electronic atomization device 100; wherein the first end 910 is oriented toward the battery cell 140 and abuts against the battery cell 140 after assembly; the second end 920 abuts the end wall of the second housing 160 at the distal end 120.

The sealing element 90 is provided with a through hole 91 penetrating from the second end 920 to the first end 910; when assembled, the through hole 91 of the sealing member 90 is longitudinally aligned with the second air hole 122.

And, a groove 911 is provided on the surface of the first end 910 of the sealing member 90, which is used for assisting the stable installation and abutment of the battery cell 140. And, the groove 911 surface of the sealing member 90 is provided with at least two air grooves 912 extending in a radial direction.

Referring to fig. 4 and 5, the end of the through hole 91 at the first end 910 is located in at least one of the at least two air slots 912, so that the external air sucked through the second air hole 122 enters the air slot 912 through the through hole 91 and passes through the air slot 912 to enter the gap between the battery cell 140 and the second casing 160.

In order to allow the first side 151 of the airflow sensor 150 to sense the above-drawn airflow, the first end 910 of the sealing member 90 has an opening 913, and the opening 913 is located at the intersection of one of the at least two air slots 912 at the center, so that the first side 151 of the airflow sensor 150 is exposed to the at least two air slots 912 for airflow communication, thereby sensing the airflow.

Likewise, at least a portion of the second side 152 of the airflow sensor 150 is also exposed at the second end 920 of the sealing member 90; to provide a reference in the sensing process of the airflow sensor 150.

Further referring to fig. 2, 3, 6 and 7, the electronic atomization device 100 further includes: the operating element 80 is disposed at the distal end 120 of the second housing 160 and is arranged to be operated by a user to rotate about the central axis m of the electronic atomization device 100 or the second housing 160. The electronic atomization device 100 reduces the amount of air entering through the first air intake hole 121 by the rotation of the operation element 80, thereby preventing the user, particularly a minor, from inhaling the aerosol. Specifically, the method comprises the following steps:

in this embodiment, the second housing 160 is provided with a fitting hole 124 on the surface of the distal end 120; the fitting hole 124 is located at the center of the second housing 160; and second housing 160 is also provided with a curved ledge 125 on the surface of distal end 120, ledge 125 defining a limited relief 1251.

The second air hole 122 is positioned outside the convex edge 125; and the ledge 125 is substantially arcuately curved; and a portion 1252 of the rim 125 near the second air hole 122 is an arc that curves radially inward, and the other portion is an arc that curves radially outward. I.e., portion 1252 of raised edge 125 has a different direction of curvature than the other portions. Also, the portion 1252 is substantially radially directed away from the retention notch 1251.

Correspondingly, the operating element 80 is configured to be cylindrical and has a first section 81 of smaller outer diameter and a second section 82 of larger outer diameter, with a step formed between them. In assembly, first section 81 extends into recessed channel 123 of second housing 160 at distal end 120, and second section 82 abuts distal end 120; the first section 81 of the operating element 80 is further provided with a hook 83 extending away from the second section 82, and the hook 83 is connected with the second housing 160 in a snap-fit manner after passing through the fitting hole 124 of the second housing 160 during assembly, and can rotate around the central axis m of the second housing 160.

As further shown in fig. 3, 6 and 7, the first section 81 of the actuating element 80 is provided with a recess 811; and by rotating the operation element 80, the overlapping degree of the notch 811 and the first air inlet hole 121 is adjusted, so as to change the size of the air inlet defined by the notch 811 and the first air inlet hole 121, and further adjust the amount of the outside air entering the electronic atomization device 100.

As further shown in fig. 3, 6 and 7, a stop 84 extending radially from the hook 83 to the inner wall of the first section 81 is also provided in the operating element 80; during the rotation of the operating element 80, the stop 84 rotates in the limit notch 1251; and provides a stop by the stop 84 against both ends of the ledge 125 bounding the spacing notch 1251.

In particular, fig. 6 shows a schematic view of the operating element 80 rotated to a first configuration or first position; as shown in fig. 6, the notch 811 of the operating element 80 substantially completely overlaps the first air inlet hole 121, and the first air inlet hole 121 is substantially completely opened; at this time, the external air enters the second casing 160 through the first air inlet holes 121, the gap 811 and the second air hole 122 in sequence, as shown by an arrow R2 in fig. 6. Of course, in the first configuration, the stop and limit is formed by the stop 84 abutting the first end of the limit notch 1251.

Further fig. 7 shows a schematic view of the operating element 80 of fig. 6 rotated about the central axis m to a second configuration or second position; as shown in fig. 7, the first intake holes 121 are partially offset from the notches 811, and an overlap portion 1211 remains in the radial direction. Of course, in the second configuration, the stop and limit is formed by the stop 84 abutting the second end of the limit notch 1251.

In implementation, the operating element 80 is in the first configuration or first position, the first air intake aperture 121 is substantially fully open; while the operating element 80 is in the second configuration or second position, only the overlapping portion 1211 of the first air intake aperture 121 is open. Further making the amount of the outside air taken in through the overlapping portion 1211 and the second air hole 122 in order when the user sucks is small as shown by an arrow R4 in fig. 7 in the second configuration or the second position greatly increases the suction resistance when the user, especially the minor sucks the suction opening a; and that the amount of airflow when drawn in the second configuration or position is insufficient to cause the pressure differential between the first side 151 and the second side 152 of the airflow sensor 150 to be greater than a preset threshold. It is therefore advantageous for the electronic vaping device 100 to prevent a user, particularly a minor, from drawing aerosol in the second configuration or second position.

Further in a preferred implementation, the length of the overlap 1211 of the first intake aperture 121 and the notch 811 in the second configuration or second position is less than 1/3 of the extension length of the first intake aperture 121; more preferably, the length of the overlapping portion 1211 of the first air intake hole 121 and the notch 811 is less than 1/4 of the extension length of the first air intake hole 121; more preferably 1/5 that is less than the extended length of the first air intake hole 121. In some implementations, the length of the overlap 1211 is less than 3 mm; more preferably, the length of the overlap 1211 is less than 2 mm.

And in some preferred implementations, as shown in fig. 7, the angle α between the two ends of the overlap 1211 and the line connecting the centers of the second casing 160 in the second configuration or second position is less than 5 degrees; more preferably, the angle α is less than 2 degrees.

The above electronic atomization device 100, by rotating the operation element 80, adjusts the amount of air entering from the first air intake hole 121; in the first configuration the first air intake apertures 121 are substantially fully open, sufficient air is able to enter and trigger the airflow sensor 150 in a puff, and there is a low resistance to draw in, controlling the output of the generated aerosol to the air intake opening a for the user to puff; whereas in the second configuration the first air intake apertures 121 are at least partially obstructed, having only an overlapping portion 1211 for the entry of a small amount of ambient air, the amount of air entering in the puff being insufficient to trigger the airflow sensor 150 to control the generation of aerosol, and a high draw resistance in the puff, which is advantageous for preventing the user, in particular the young, from drawing in aerosol.

In a further preferred embodiment, the operating element 80 is in the second configuration or second position, the notch 811 being completely offset from the first air intake aperture 121; the first air intake holes 121 are completely closed in the second configuration or second position, and external air cannot enter the electronic atomization device 100 at all during inhalation, which is also practical for preventing users, especially juveniles, from inhaling aerosol.

The above electronic atomization device 100, in the second configuration, can prevent the airflow sensor from triggering and generating an aerosol, which is advantageous to prevent a user, particularly a minor, from drawing. And still have a small amount of air flow when drawing in the second configuration to prevent minors from perceiving that the electronic atomization device 100 is locked.

Further, the circuit board is also configured to allow the cells 140 to provide power to the heating element 30 when the operating element 80 is in the first configuration; and inhibits or prevents the cell 140 from providing power to the heating element 30 when the operating element 80 is in the second configuration. Further in some implementations, the electronic atomization device 100 can detect the position of the operating element 80 through a sensing device, such as a distance sensor, a light sensor, etc., to determine the configuration state of the operating element 80; and preventing aerosol generation in the second configuration.

a first housing 170a adjacent to and defining a proximal end 110 a; the first housing 170a defines a suction nozzle 171 a; similarly, a reservoir chamber for storing the liquid substrate, an atomizing assembly for atomizing the liquid substrate, and an aerosol output tube for outputting the aerosol to the proximal end 110a are disposed in the first housing 170 a;

the surface of the second housing 160a at the distal end 120a is provided with a fitting hole 124a, substantially centrally located; the ledge 125a is configured in an arcuate shape that at least partially surrounds the mounting aperture 124a, and a limited relief 1251a is defined between the ends of the ledge 125 a.

The second housing 160a is further provided with an operating element 80a on the distal end 120a, the operating element 80a having a thin shape perpendicular to the longitudinal direction of the electronic atomization device 100; for example, the operating element 80a is in the shape of a thin sheet or plate; the operating element 80a is provided with a hook 83a extending in the thickness direction, and is connected with the second housing 160a after penetrating through the hook 83a to the assembling hole 124 a; the hook 83a is arranged offset from the center of the operating element 80 a. When assembled, the operating element 80a can rotate about the center axis of the second housing 160a, the hook 83a, as indicated by the arrow R3 in fig. 10 and 11.

In particular, fig. 10 shows a schematic view of the operating element 80a rotated to a first configuration or first position; in the first configuration or first position, the operating element 80a completely opens or reveals the first air intake hole 121a and completely closes or obstructs the second air intake hole 122 a; the external air is allowed to enter into the second casing 160a from the first air intake holes 121a as indicated by an arrow R2 in fig. 9 during the suction. And the air quantity entering from the first air inlet hole 121a is enough to ensure that the suction resistance is low, and an air flow sensor can be triggered to control the generated aerosol to be output to the air suction opening A for the suction of a user. Of course, in this first configuration or first position, the operating element 80a forms a stop and a stop against the first end of the stop notch 1251 a.

Further figure 11 shows a schematic view of the operating element 80a rotated to a second configuration or second position; in the second configuration or the second position, the operating element 80a completely opens or reveals the second air intake hole 122a and completely closes or blocks the first air intake hole 121 a; the external air is allowed to enter the second casing 160a from the second air intake holes 122a in drawing along an arrow R4 shown in fig. 9. Since the second air intake holes 122a have a smaller aperture or area, there is a higher draw resistance in the puff and the amount of air entering is small enough not to trigger the airflow sensor to control the generation of aerosol, which is advantageous for preventing the user, especially the young, from drawing aerosol.

In some preferred implementations, the area of the second air intake holes 122a is less than 1/3 of the area of the first air intake holes 121 a; more preferably, the area of the second intake holes 122a is smaller than 1/5 of the area of the first intake holes 121 a.

In some preferred implementations, the aperture of the first air intake holes 121a is about 2-5 mm; the aperture of the second air intake hole 122a is less than 1 mm.

As further shown in fig. 10, an angle α between centers of the first air intake holes 121a and a line connecting the center of the second air intake hole 122a and the center of the second housing 160a is 90 degrees or less.

Further fig. 12 to 16 show schematic views of an electronic atomization device 100 of yet another embodiment; in this embodiment, the electronic atomization device 100 similarly includes:

a first housing 170b adjacent to and defining a proximal end 110 b; the first housing 170b defines a suction nozzle 171 b; similarly, a reservoir chamber for storing the liquid substrate, an atomizing assembly for atomizing the liquid substrate, and an aerosol output tube for outputting the aerosol to the proximal end 110b are disposed in the first housing 170 b;

a second housing 160b adjacent to and defining a distal end 120 b; the second casing 160b is provided therein with a cell for supplying power, a control circuit board, an airflow sensor for sensing suction airflow, and the like.

The second housing 160b is provided at the distal end 120a with:

a concave groove 123 b; a convex edge 125b located in the concave groove 123 b; the ledge 125b defines a restraining notch 1251 b;

a mounting hole 124b in the ledge 125b for the hook 83b of the operating element 80b to pass through and connect;

a second air inlet 122b in the ledge 125b for air to enter the second housing 160 b.

The electronic atomization device 100 further includes:

an operating element 80b disposed at the distal end 120b of the second housing 160 b; the operating element 80b is cylindrical in shape; the actuating element 80b has a first section 81b and a second section 82 b; wherein the outer diameter of the first section 81b is smaller than the outer diameter of the second section 82 b. Further, when assembled, the first section 81b extends into the recessed groove 123b of the second housing 160b, and the second section 82b abuts against the distal end 120 b.

A hook 83b extending away from the second section 82b is arranged in the first section 81b of the operating element 80b, and penetrates through the mounting hole 124b to be connected to the second housing 160 b; and it is the operating element 80b that can rotate about the center axis m of the second housing 160b or the hook 83b, as indicated by the arrow R3 in fig. 14 and 15.

A stop portion 84b extending from the hook 83b to the inner wall of the first section 81b in the radial direction is further arranged in the first section 81b of the operating element 80 b; during the rotation of the operating element 80b, the stop 84b rotates in the limit notch 1251 b; and provides a stop by stop 84b abutting the two ends of ledge 125b defining a limit notch 1251 b.

The operating element 80b is further provided with a first air inlet 85b penetrating in the axial direction, as shown by an arrow R2 in fig. 13, and external air can enter the second casing 160b through the first air inlet 85b and the second air inlet 122b during suction.

A stop 86b is also provided in the first section 81b of the operating element 80b for blocking the second air inlet 122b of the second housing 160 b.

In particular, fig. 14 shows a schematic view of the operating element 80b rotated to a first configuration or first position; referring to FIG. 14, the stop 86b is fully offset from the second inlet opening 122b, such that the second inlet opening 122b is fully open or exposed; at this time, the external air enters the second casing 160b through the first air inlet 85b and the second air inlet 122b in sequence. Of course, in the first configuration, the stop and limit is formed by the stop 84b abutting the first end of the limit notch 1251 b.

Further fig. 15 shows a schematic view of the operating element 80b of fig. 14 rotated about the central axis m to a second configuration or second position; referring to FIG. 15, the stop 86b substantially blocks a portion of the second inlet opening 122 b; of course, the second air inlet 122b still retains the exposed portion 1221b that is not blocked. Of course, in the second configuration, the stop and limit is formed by the stop 84b abutting the second end of the limit notch 1251 b.

In practice, the operating element 80b is in the first configuration or first position, the second air inlet 122b is substantially fully open; and the operating element 80b is in the second configuration or second position, only the exposed portion 1221b of the second air inlet 122b that is unobstructed is open.

When a user draws in the first configuration, sufficient air can enter the second housing 160b through the second air inlet 122 b; the aerosol has low suction resistance in the suction process, and can trigger the airflow sensor to control the generated aerosol to be output to the air suction port A for the suction of a user.

While in the second configuration, the user draws little air from the exposed portion 1221b into the second housing 160b, resulting in a greater resistance to draw in the second configuration and insufficient airflow volume to trigger the airflow sensor when drawn in the second configuration or position. It is therefore advantageous for the electronic vaping device 100 to prevent a user, particularly a minor, from drawing aerosol in the second configuration or second position.

Or in yet other variations, the operating element 80b completely obscures the second air inlet 122b in the second configuration, leaving the second air inlet 122b completely closed without exposure; it is further advantageous to completely prevent the user, especially the pre-adults, from sucking the aerosol.

As further shown in fig. 16, the surface of the second housing 160b in this embodiment is provided with first and second marks 161b and 162b arranged at intervals in the circumferential direction; correspondingly, a pointing mark 87b is provided on the surface of the operating element 80 b. Accordingly, the operating element 80b is directed towards the first marker 161b or close to the first marker 161b or in contact with the first marker 161b in the first configuration at the directional marker 87 b; and the operating element 80b in the second configuration is oriented with the orientation mark 87b directed toward the second indicia 162b or adjacent to the second indicia 162b or in contact with the second indicia 162 b. Further, a first mark 161b indicates a rotational position where air can maximally enter the operation element 80b of the electronic atomization device 100; and a second mark 162b indicates a rotational position where air can minimally enter the operating element 80b of the electronic atomization device 100, so as to prompt the user that the operating element 80b is currently located. More preferably, when the user, such as an adult, rotates the operating member 80b to point at the first marker 161b to perform suction, the operating member 80b is rotated to point at the second marker 162 b; it is advantageous to prevent the generated aerosol from being drawn by minors.

It should be noted that the preferred embodiments of the present application are shown in the specification and the drawings, but the present application is not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and variations can be made in the above description, and all such modifications and variations should be within the scope of the appended claims of the present application.
