Description

Electronic atomizing device

Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an electronic atomization device.

Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release the compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As one example, there are electronic atomizing devices that typically contain a liquid that is heated to vaporize it, producing an inhalable aerosol. An electronic atomizing device is known, having an air inlet and an air flow sensor disposed at a distal end, the air flow sensor having a first side and a second side that are air flow isolated from each other, wherein the first side communicates with an air flow channel through the electronic atomizing device to sense pressure within the air flow channel upon aspiration, the second side communicates with the ambient atmosphere to sense pressure of the ambient atmosphere, and the user's aspiration is determined based on a difference between the sensed pressure of the first side and the sensed ambient atmosphere pressure of the second side being greater than a preset threshold. Such electronic nebulizers normally close the air inlet to prevent air from entering and exiting when aerosol is not desired to be output, and the user, especially a minor, draws when the air inlet is closed, and while no airflow through the electronic nebulizers and no aerosol output is established, the first side of the airflow sensor can still be triggered by a pressure drop in the airflow channel caused by the action of drawing and thus a pressure difference exceeding a threshold value with the second side, causing a safety hazard.

In some embodiments, the outer body or housing of the electronic atomization device 100 substantially defines an outer surface of the electronic atomization device 100. In the particular embodiment shown in FIGS. 1-2, the electronic atomization device 100 includes:

After the distal end 120 of the second housing 12 is removed or disassembled, the distal end 120 of the casing 10 is opened, thereby allowing the battery cells 70 to be removed or replaced from the distal end 120 of the casing 10/second housing 12. Specifically, after removing the end cap 20, the distal end 120 of the housing 10 is opened, so that the battery cell 70 can be removed or withdrawn from the distal end 120 of the housing 10 by a slight shaking or flicking.

Referring to fig. 3-5, the assembled rear end cap 20 extends at least partially from the distal end 120 into the housing 10/second shell 12, and a first air inlet 21 is disposed on the end cap 20 for external air to enter the electronic atomization device 100.

As shown in fig. 1 to 5, the electronic atomizing device 100 further includes:

an operating mechanism 30 is at least partially received and mounted within the end cap 20 and is operable by a user to selectively open and close the first air inlet 21 on the end cap 20.

As shown in fig. 1 to 5, the operating mechanism 30 includes:

An operating element 31, a sealing element 32, a connecting element 34 and an elastic element 33.

As shown in fig. 3 to 6, a plurality of flanges 621 circumferentially surrounding the second support portion 620 are disposed in addition to the second support portion 620 of the bracket 60, and grooves are defined between the adjacent flanges 621. As shown in fig. 3 to 6, the flange 621 is disposed between the sealing ring outside the first support portion 610 and the sealing ring outside the third support portion 630 in the longitudinal direction of the bracket 60.

According to the embodiment shown in fig. 3 to 6, the first receiving cavity 611 includes a first section 6111 and a second section 6112 arranged in order in the longitudinal direction, wherein the first section 6111 is close to the first end of the bracket 60, the first section 6111 is in a shape in which an inner side surface is inclined in a cone shape or a wide mouth shape, and the second section 6112 is in a columnar shape in which a diameter is substantially constant. In this embodiment, the first liquid guiding element 51 is received and held in the second section 6112 of the first receiving cavity 611, and the first liquid guiding element 51 avoids the tapered first section 6111 and is absorbed by the liquid matrix in the liquid storage cavity 112 of the tapered first section 6111 being guided to the upper surface of the first liquid guiding element 51. In this embodiment, the first liquid guiding member 51 is not flush with the first end of the bracket 60 after assembly, for example, in fig. 6, with a distance of about 5 to 10mm therebetween.

As shown in fig. 3-6, the second support portion 620 defines a second receiving chamber 627 therein for at least partially mounting and receiving the tubular element 14 and atomizing assembly. Specifically, after assembly, the tubular member 14 is at least partially inserted through the first receiving cavity 611 and into the second receiving cavity 627 of the bracket 60, and the tubular member 14 and the bracket 60 form a seal therebetween by an interference fit. And, there is no flexible sealing element between the tubular member 14 and the stent 60. The first end of the holder 60 is open or has a first opening through which the first liquid guiding element 51 is received from the first end into the first receiving chamber 611 and/or through which the tubular element 14 and/or the atomizing assembly is received from the first end through the first receiving chamber 611 into the second receiving chamber 627.

As shown in fig. 3 to 6, the third supporting portion 630 of the bracket 60 is further disposed therein:

A third receiving chamber 631 for receiving or mounting the airflow sensor 15 and the partition 16. The airflow sensor 15 is received and mounted within the third receiving chamber 631 of the bracket 60, disposed away from the reservoir 112. In the embodiment of fig. 3 to 6, the air flow sensor 15 is in the shape of a sheet or a disc or a column, and the axis of the air flow sensor 15 is arranged parallel to the longitudinal direction along the holder 60. The partition 16 is flexible, for example made of silicone or thermoplastic elastomer, and encloses the air flow sensor 15. As shown in fig. 3 to 7, at least one second air inlet 161 is arranged on the partition 16 to penetrate in the longitudinal direction for air to pass through the partition 16. In the embodiment of fig. 3-6, the air flow sensor 15 is arranged offset from the longitudinal center axis of the electronic atomizing device 100, e.g. in fig. 4 and 5, the air flow sensor 15 is arranged near the left side.

As shown in fig. 3-6, an air flow channel is disposed within the electronic atomizing device 100 defining an air flow path from the first air inlet 21 through the atomizing assembly to the air outlet 113 for delivering aerosol to the air outlet 113 for inhalation by a user. The air flow path within the electronic atomizing device 100 is commonly defined by a plurality of components, such as shown by arrow R2 in fig. 3-6.

As shown in fig. 6, the bracket 60 is disposed thereon:

A first channel portion 623 extending from the third receiving chamber 631 to an outer surface of the second supporting portion 620 of the bracket 60 and defining a communication port 624 on the outer surface of the second supporting portion 620;

A second channel portion 625 extends from an outer surface of the second support portion 620 into the second receiving chamber 627. Thus, during pumping, the air flow path through the holder 60 is as indicated by arrow R2 in fig. 6, from the third receiving chamber 631 through the first channel portion 623 into the outer surface of the second support portion 620 and flows around the holder 60 in the recess of the outer surface of the second support portion 620 to the second channel portion 625 and then through the second channel portion 625 into the second receiving chamber 627 to carry the aerosol output generated by the atomizing assembly.

The complete airflow path of the electronic atomizing device 100 during suction is shown by the arrow R2 in fig. 3 to 6, when the sealing member 32 of the operating mechanism 30 is moved to the open position, the external air introduced from the first air inlet 21 sequentially passes through the gap between the electric core 70 and the housing 10, the holding member 18, and then enters the third accommodating chamber 631 of the holder 60, and then passes through the second air inlet 161 of the partition 16, flows into the first passage portion 623, flows through the grooves of the surface of the holder 60 to the second passage portion 625, finally enters the tubular member 14 from the second passage portion 625, and carries the aerosol generated by the atomizing assembly to be delivered from the aerosol output tube 111 to the air outlet 113.

In fig. 6-9, the second air inlet 161 is a through hole extending through the divider 16, or in yet other variations, the second air inlet 161 is a groove located on the outside surface of the divider 16, and the second air inlet 161 is defined by the groove on the surface of the divider 16 and the bracket 60 together after the divider 16 is assembled in the bracket 60.

As shown in fig. 6 to 9, the partition 16 is substantially configured in a cylindrical shape, and the partition 16 is substantially adapted to the cross section of the third accommodation chamber 631 of the bracket 60. And, after assembly, the partition 16 has a distance d1 of about 3 to 5mm from the top wall of the third receiving chamber 631 in the longitudinal direction of the bracket 60, and a distance d2 of about 4 to 8mm from the second end of the bracket 60 from the partition 16. As shown in fig. 6 to 9, the second inlet port 161 of the partition 16 has a first port 1611 and a second port 1612 opposite to each other, wherein the first port 1611 is an outlet port, the first port 1611 is adjacent to and communicates with the outlet port 113, and the second port 1612 is an inlet port, and the second port 1612 is adjacent to and communicates with the first inlet port 21.

In order for the airflow sensor 15 to accurately sense the airflow through the electronic atomizing apparatus 100 in the user's suction, the airflow sensor 15 includes first and second sensing surfaces 151 and 152 that are opposite in the longitudinal direction of the electronic atomizing apparatus 100. The partition 16 circumferentially wraps the airflow sensor 15, and exposes the first sensing surface 151 and the second sensing surface 152. In an embodiment, the first sensing surface 151 and the second sensing surface 152 are isolated from each other. The first sensing surface 151 is in air flow communication with the first port 1611 of the second air inlet 161 through a space defined by the spacing d1, and the second sensing surface 152 is in air flow communication with the second port 1612 of the second air inlet 161 through a space defined by the spacing d 2.

The above first sensing surface 151 and the second sensing surface 152 of the airflow sensor 15 are brought into communication through the second air inlet 161. When the device is used for sucking, the pressure drop sensed by the first sensing surface 151 is larger than the pressure drop sensed by the second sensing surface 152, the air flow sensor 15 determines the sucking action of a user and outputs a trigger signal when the difference value of the pressure drop of the first sensing surface 151 and the pressure drop of the second sensing surface 152 is larger than a preset threshold value according to the sucking air flow, and the electronic atomization device 100 controls the electric core 70 to output power to the heating element 40 to atomize the liquid to generate aerosol according to the trigger signal of the air flow sensor 15. And when the user draws while the first air inlet 21 is blocked or closed by the sealing member 32 of the operating mechanism 30, no air flow is established through the electronic atomizing apparatus 100, and the pressures sensed by the first sensing surface 151 and the second sensing surface 152 of the air flow sensor 15 are substantially simultaneously lowered and comparable while the draw resistance is large, at which time the air flow sensor 15 cannot form a trigger.

According to fig. 5, the air flow sensor 15 is arranged remote from the distal end 120. Specifically, the first sensing surface 151 is oriented toward the proximal end 110 with a first distance d11 from the proximal end 110, and the second sensing surface 152 is oriented toward the distal end 120 with a second distance d12 from the distal end 120. Wherein the second distance d12 is larger than the first distance d 11. Accordingly, the airflow sensor 15 is relatively closer to the proximal end 110.

In some embodiments, such as shown in FIG. 7, the cross-sectional area of the second air inlet 161 is varied, at least a portion of the second air inlet 161 is tapered in FIG. 7, at least a portion of the cross-sectional area of the second air inlet 161 is decreasing toward the first inlet 1611, and turbulence is created as air flows through the second air inlet 161 during pumping, which is advantageous to promote a pressure differential across the first sensing surface 151 and the second sensing surface 152. Or in still other varying embodiments, the cross-sectional area of the second inlet 161 may be constant.

In the embodiment shown in fig. 7 and 8, the number of second air inlets 161 is two, or in still other variations, the number of second air inlets 161 may be only one or more.

In still other embodiments, the minimum cross-sectional area of the second inlet port 161 determines the suction resistance and pressure drop difference created in the suction, i.e., the cross-sectional area of the second inlet port 161 at the minimum aperture 1613 in fig. 7. In some embodiments, the cross-sectional area of the smallest aperture 1613 of the second air inlet 161 is between 0.8 and 2.3mm ². In some more preferred embodiments, the cross-sectional area of the second inlet 161 at the smallest aperture 1613 is between 1.0 and 2.26mm ². The following table shows the results of the cross-sectional area at the minimum aperture 1613 of the second inlet port 161 and the pressure differential across the suction resistance and the airflow sensor 15 during suction in various embodiments, which is advantageous for triggering the airflow sensor 15 while maintaining a suitable suction resistance.

In some embodiments the minimum cross-sectional area of the second inlet 161 is such that in use a pressure drop across the second inlet 161 is caused to drive the airflow sensor 15 to actuate, preferably the second inlet 161 is arranged to form a pressure differential of between 100 and 600 Pa in use.

In some embodiments, the area of the first air inlet 21 is greater than 1.5 times the smallest cross-sectional area of the second air inlet 161. In some preferred embodiments, the area of the first air inlet 21 is greater than 2.5 times or more the smallest cross-sectional area of the second air inlet 161, or the area of the first air inlet 21 is greater than 3.5 times or more the smallest cross-sectional area of the second air inlet 161. In some preferred embodiments, the area of the first air inlet 21 is about 4-10 mm ².

As shown in fig. 4 to 9, the complete air flow path through the electronic atomizing device 100 includes:

the first portion between the first air inlet 21 and the second port 1612 of the second air inlet 161 is primarily defined by the gap between the battery cell 70 and the second housing 12;

the second portion, located between the first port 1611 of the second inlet port 161 and the outlet port 113, is primarily defined by the support 60 and the aerosol outlet tube 111 together. In an embodiment, the average cross-sectional area of the second portion is smaller than the average cross-sectional area of the first portion.

In some embodiments, the length of the second air inlet 161 is about 5-12 mm. That is, the separator 16 has a thickness of about 5 to 12mm.

It should be noted that the description of the application and the accompanying drawings show preferred embodiments of the application, but are not limited to the embodiments described in the description, and further, that modifications or variations can be made by a person skilled in the art from the above description, and all such modifications and variations are intended to fall within the scope of the appended claims.
