DETAILED DESCRIPTIONS

In the following description, reference is made to the accompanying drawings, which illustrate how to practice the present disclosure through illustration.

Before proceeding to the description herein, the applicants would like to point out that the terms and descriptions (upper, lower, etc.) of the position and aspects herein are described with reference to the arrangement of units or apparatus in general use as shown in the accompanying drawings, in order to facilitate the description and enable those skilled in the art to understand the principles of the present invention, and are not intended to be limited.

According to some embodiments of the present invention, an atomization unit assembly, a bracket, a heating core assembly, and an electrode assembly are provided. According to some embodiments of the present invention, an atomization apparatus comprising an atomization unit assembly, a main body unit, a suction nozzle unit, and a base assembly is also provided. The atomization unit assembly and the atomization apparatus of the present invention can atomize liquids such as electronic cigarette oil and pharmaceutical liquid, which can be collectively referred to as medium to be atomized herein. The medium to be atomized is atomized (specifically, heated and atomized by the heating core assembly) to generate aerosols for user suction.

FIGS. 1-3 show views of an existing atomization apparatus, wherein FIG. 1 is a front view of the existing atomization apparatus; FIG. 2 is a cross-sectional view of the existing atomization apparatus; FIG. 3 is a cross-sectional view of the existing atomization apparatus.

Specifically, FIGS. 1-3 show the atomization apparatus with the heating surface facing downwards in the prior art. The “heating surface facing downwards” refers to the orientation shown in the figure. In particular, “heating surface facing downwards” refers to the surface facing downwards of the heating core (heating material) that atomizes the atomization medium; more specifically, it refers to the orientation of the heating surface such that the heated and atomized aerosol is directed downwards/away from the heating surface with respect to the apparatus. In the arrangement of “heating surface facing downwards”, the direction in which the aerosol leaves the spraying/heating surface is opposite to the direction in which the aerosol passes through the apparatus to be sucked by the user (i.e., “turning 180 degrees”). Furthermore, it should be noted that the “heating surface facing downwards” in the present invention covers a situation where the heating surface is generally downwards. That is to say, in the case where the “heating surface is facing downwards”, the heating surface is in a “parallel” orientation in the figure, while the present application covers the case where the heating surface is not parallel. The present invention is applicable to situations where the angle between the direction in which the aerosol is sprayed from the heating surface and the direction in which the aerosol passes through the apparatus to be sucked by the user is greater than 90 degrees.

As best described in the cross-sectional view of the existing atomization apparatus shown in FIG. 3, the heating surface generates a downward aerosol jet flow F1, and causes an overall upward aerosol flow F2 under the action of user suction, as the aerosol flow F2 proceeds upward, it is easy to form a vortex V inside the apparatus (especially at the position where local enclosure (such as a corner) are formed). The vortex V forms a local circulation of the aerosol, which can easily cause condensation of aerosols and accumulation of condensed aerosols in the area where the vortex V is generated. The condensation of aerosols and the accumulation of condensed aerosols waste the atomization liquid and reduce the user's suction experience; at the same time, the accumulated condensation liquid will corrode the electrical components inside the apparatus, causing damage to the apparatus; furthermore, in the case where the apparatus body is made of transparent and semi-transparent materials, the condensation of aerosols and the accumulation of condensed aerosols visually appear as stains, resulting in an unattractive visual effect.

The atomization unit assembly and the atomization apparatus comprising the atomization unit assembly proposed by the present invention are intended to solve the above-mentioned problems that occur in the atomization solution where the heating surface faces downwards in the prior art.

Referring to FIGS. 4-5, which are perspective and front views of the atomization apparatus according to some embodiments of the present application.

As shown in the figures, the atomization apparatus according to some embodiments of the present application comprises a suction nozzle unit 1, a main body unit 2, and a base assembly. The main body unit is connected to the suction nozzle unit, the base assembly is connected to the main body unit. In some embodiments, the suction nozzle unit 1 and the main body unit 2 can be integrally formed. The suction nozzle unit 1 comprises a suction nozzle, which is a component for contacting with the user's lips, its shape is any shape suitable for engaging with the user's lips to suck the aerosol generated by the atomization unit assembly/atomization apparatus, such as a cylinder shape, a tapered cylindrical shape, a tapered cylindrical shape with a cut-off portion, a cylindrical shape with a flat portion, a flat shape, etc. Any shape configured to engage the user's lips for the suction of aerosols is encompassed by the present application. It is easy to understand that the suction nozzle unit 1 defines an aerosol channel therethrough, the aerosol channel leads to an air outlet through which the aerosol passes for users to suck. The main body unit 2 may be an elongated body comprising a longitudinal axis and having a cross-section which may be circular or elliptical, or may be flat.

The main body unit 2 partially defines a storage space for the atomization medium and is configured for mounting the atomization unit assembly therein. The main body unit 2 may be partially or completely made of transparent or semi-transparent materials, or it may also be made of opaque materials. The transparent, semi-transparent, or opaque materials used to make the main body unit 2 are well-known in this field and will not be repeated herein.

Further detailed description of the atomization apparatus of the present invention is provided with reference to FIGS. 6-7, wherein FIG. 6 is a cross-sectional view (a cross-sectional view along the A-A line of FIG. 4) of the atomization apparatus according to some embodiments of the present application; FIG. 7 is a cross-sectional view (a cross-sectional view along the B-B line of FIG. 4) of the atomization apparatus according to some embodiments of the present application.

As shown in FIGS. 6-7, the main body unit 2 comprises an atomization medium chamber assembly 21, the atomization medium chamber assembly 21 and the bracket 22 of the atomization unit assembly described below partially define the atomization medium storage space for storing atomization liquid or atomization medium (the atomization liquid and the atomization medium can be used interchangeably herein). A vertical air pipe is provided in the main body unit 2, the air pipe defines the aerosol channel; when the suction nozzle unit 1 is mounted on the main body unit 2, that is, when the suction nozzle unit 1 and the main body unit 2 are connected to each other, the aerosol channel in the air pipe is in fluid communication or alignment with the aerosol channel in the suction nozzle unit 1. The air pipe and the main body unit 2 may be formed integrally or may be separate elements. The air pipe may be positioned centrally relative to the main body unit 2 (its central axis coincides with the longitudinal axis of the main body unit), in which case the air pipe may be referred to as a central air pipe. The air pipe may also be set without being centered, and its central axis does not coincide with the longitudinal axis of the main body unit. One end of the air pipe is docked (connected and forming an airtight seal) with the aerosol discharge port on the bracket 22 of the atomization unit assembly described below, so that the aerosol led from the aerosol discharge port of the atomization unit assembly passes through the aerosol channel in the air pipe and then through the aerosol channel in the suction nozzle unit.

The atomization medium chamber assembly 21 and the bracket 22 of the atomization unit assembly partially define the storage space for the atomization medium. More specifically, as shown in the figure, the inner wall of the main body unit 2, the outer wall of the air pipe, and the end surface of the bracket 22 with an aerosol discharge port described below partially define the storage space for the atomized medium. The main body unit 2 is provided with a liquid injection port and a liquid injection plug blocking the liquid injection port at one end, preferably at the end connected to the suction nozzle unit 1. The atomization medium/atomization liquid may be injected into the storage space for the atomization medium through the liquid injection port for filling/reloading/supplementing the atomization medium.

The atomization unit assembly 23 may be partially or fully mounted in the main body unit 2. The atomization unit assembly 23 comprises a bracket 22, a heating core assembly, and an electrode assembly. The bracket 22 is preferably made of an opaque material. The bracket 22 is mounted in the main body unit 2 in a form-fitting manner, that is, the outer contours of the bracket 22 and the main body unit 2 are the same in the direction perpendicular to the longitudinal axis, but their sizes are different. The bracket 22 has a longitudinal axis and a wall that defines the internal space of bracket 22. The heating core assembly is assembled in the internal space of the bracket 22 and abuts against the electrode assembly, wherein the heating core assembly comprises a heating surface for heating and atomizing the atomization medium to generate aerosols; the electrode assembly is used to supply power to the heating core assembly. The bracket 22 of the atomization unit assembly 23 is provided with an inlet channel 214, as shown in FIGS. 7-8. Specifically, the bracket 22 is assembled in the main body unit 2 in such a way that its outer wall forms a liquid tight seal with the inner wall of the main body unit 2, and that the aerosol discharge port provided on the bracket 22 is connected to the air pipe. In this way, the atomization medium chamber assembly 21, the air pipe and the end surfaces around the aerosol discharge port of the bracket define an atomization medium chamber. The bracket 22 of the atomization unit assembly 23 is provided with a liquid inlet channel 214 on the end surface around the aerosol discharge port of the bracket, thereby allowing the medium to be atomized in the atomization medium chamber to be introduced into the bracket 22 and be in contact with the heating core assembly 232. The atomization medium is atomized at the atomization surface of the heating core assembly 232 and generates aerosol that is sprayed downward into the atomization chamber 215, as shown in FIG. 9.

It can be seen therefrom that bracket 22 has a longitudinal axis and has an aerosol discharge port that is connected to the air pipe. The end surface around the aerosol discharge port on bracket 22, (the inner wall of) the atomization medium chamber assembly 21, (the outer wall of) the air pipe define the storage space for accommodating the atomization medium to be atomized. For this purpose, the air pipe is connected/docked with the aerosol discharge port and forms a gas-liquid seal, preferably by means of a seal member, such as an O-ring, and a liquid tight seal is also formed between the outer wall of the bracket and the inner wall of the main body unit 2 preferably by means of a seal member, such as an O-ring. The seal member is preferably mounted in a groove provided on the outer wall of the bracket 22 (as shown in FIGS. 6-11 and 12-16, etc.). In addition, a liquid inlet channel 214 is also provided on the end surface around the aerosol discharge port on the bracket 22, which is used to allow the atomization medium in the storage space for the atomization medium to enter the inside of the bracket. More specifically, the atomization medium enters the bracket and comes into contact with the heating core assembly 232 installed inside the bracket. More specifically, the atomization medium comes into contact with the heating surface of the heating core assembly 232, which is heated and atomized to generate aerosols entering the atomization chamber 215. The atomization core assembly or heating core assembly used to atomize the atomization liquid/atomization medium to generate aerosols comprises an atomization core seat, a liquid guide rod, an atomization core, etc., which are well-known in this field and will not be repeated herein.

In addition to defining the internal space in which the heating core assembly is assembled, the bracket 22 also comprises a wall with a thickness that defines the internal space, and at least one airflow channel 2313 is provided inside the wall (see FIG. 10). The airflow channel is communicated with the atomization chamber 215 and the aerosol discharge port docked with the air pipe to guide the atomized aerosol in the atomization chamber to pass through the airflow channel and be discharged from the aerosol discharge port to enter the air pipe.

Referring to FIGS. 10-11 for further description, the suction nozzle unit 1 and the main body unit 2 are connected in the above manner, and elements such as the bracket 22 and the heating core assembly 232 are mounted in the main body unit 2 in the above manner, at least one airflow channel 2313 is provided in the wall of the bracket 22, and at least one air inlet (such as a first air inlet hole 301 and/or a second air inlet hole 302) is provided on the base assembly that is docked/connected to the main body unit 2. The medium to be atomized/atomization liquid in the atomization medium chamber enters the internal space defined by the bracket 22 through at least one inlet channel 214 provided on the end surface of the bracket 22, and comes into contact with the heating core assembly 232 mounted in the internal space. The medium to be atomized/atomization liquid is heated by the atomization surface of the heating core assembly 232 to generate aerosol sprayed into the atomization chamber 215 (indicated by a downward arrow). When a user is using it, a negative pressure is formed by suction at the air outlet 11 of the suction nozzle, so that external air enters the atomization chamber 215 from the air inlet of the first air inlet hole 301 and/or the second air inlet hole 302. The atomized aerosol is carried away from the atomization chamber 215 through the airflow channel 2313, and reaches the aerosol discharge port provided on the bracket 22, and enters the air pipe, and then reaches the suction nozzle unit 1 through the airway of the air pipe, and through the airway in the suction nozzle unit 1, it reaches the air outlet 11 of the suction nozzle for the user to suck.

FIG. 9 also shows an electrode assembly that is in contact with the heating core assembly 232, wherein the heating core assembly 232 and the electrode assembly partially define the atomization chamber; In embodiments where the atomization apparatus also comprises a base assembly, the base assembly, the heating core assembly, and the electrode assembly define the atomization chamber, and the base is provided with one or more air intakes for introducing external air. The electrode assembly comprises both positive and negative electrodes (pins), and optionally comprises an electrode mounting base through which the (metal) electrode passes.

FIGS. 15 and 17 show the different cross-sectional shapes of the airflow channels inside the wall of the bracket. In particular, when observed in a plane passing through the longitudinal axis of the main body unit and/or bracket and passing through the airflow channel, the airflow channel is in a straight, arched, or S-shaped shape, but is not limited to these. Any cross-section shaped airflow channel, as long as it is set inside the wall of the bracket and configured to connect the atomization chamber and aerosol discharge port, may be applicable to the present invention.

FIGS. 15-17 show the different configurations of the end surface of the bracket provided with an aerosol discharge port relative to the longitudinal axis.

That is, referring to the direction and orientation of the attached figure, the end surface can be parallel to or at an angle to the liquid level of the atomization medium contained in the atomization medium chamber.

As mentioned above, by arranging the airflow channel inside the wall of the bracket, the present application reduces or even eliminates the vortex of atomized gas in the atomization apparatus during the process of the atomized gas leading to the aerosol discharge port, thereby reducing the generation of condensate, improving the user experience, and increasing the utilization rate of atomization medium, and further reducing the possibility of condensate accumulation eroding the circuit/electronic components in the apparatus, thereby extending the service life of the apparatus. To further reduce the negative impact of condensation, in some embodiments, as shown in FIG. 18, a groove (condensate collection groove) is formed on the side wall of the airflow channel 2313 to collect the condensed atomization medium. In some embodiments, the groove is defined by protrusions protruding from the sidewall defining the airflow channel. In some embodiments, the groove extends spirally or circumferentially relative to the longitudinal axis of the bracket or main body unit.
