Description

Atomizing unit assembly and atomizing device

Technical Field

The present application relates generally to the field of atomization, and more particularly to an atomization unit assembly and an atomization device.

Background

The atomizing device generally includes an atomizing unit assembly and a power source that powers the atomizing unit assembly, which converts electrical energy into thermal energy, under which the aerosol-generating medium is converted into aerosol for inhalation by a user.

The aerosol flow channel of the existing atomizing device after an atomizing medium is atomized usually has two structures, one is that the atomized aerosol can be directly sucked away through an air pipe (such as a central pipe) under the condition that an atomizing heating surface is on the inner side, and an atomizing core of the atomizing device is mainly a net-shaped heating wire and a spiral heating wire; the other is that under the condition that the atomization heating surface faces downwards, atomized aerosol can be sucked away through an air pipe after being turned 180 degrees through a section of zigzag channel, and the atomization device is mainly a ceramic coating atomization core. In the case of the second structure, the atomizing face and the flow channel of the aerosol have the following problems: because the atomizing surface is downward, the aerosol passes through a relatively complex airflow path, which produces excessive condensate. This both wastes the aerosolized liquid and reduces the user's aspiration experience. At the same time, the accumulated condensate can attack electrical components within the device, causing damage to the device.

Detailed Description

In the following description, reference is made to the accompanying drawings which show, by way of illustration, how the application may be practiced.

Before proceeding with the description herein, applicant notes that the terms and depictions (upper, lower, etc.) of the locations and aspects herein are described with reference to the arrangement shown in the drawings or where the units or devices are in general use, for ease of description so as to make those skilled in the art aware of the principles of the present invention and are not intended to be limiting.

According to some embodiments of the present invention, there is provided an atomizing unit assembly, a holder, a heat generating core assembly, and an electrode assembly. There is also provided, in accordance with some embodiments of the present invention, an atomizing device including an atomizing unit assembly, the body unit, the nozzle unit, and the base assembly. The atomizing unit assembly and the atomizing device of the present invention can atomize liquids such as e-cigarette oil, medical liquids, etc., which may be collectively referred to herein as a medium to be atomized. The medium to be atomized is atomized (specifically, heated and atomized by the wick assembly) to generate an aerosol for inhalation by the user.

FIGS. 1-3 illustrate views of a prior art atomizing device, wherein FIG. 1 is a front view of the prior art atomizing device; FIG. 2 is a cross-sectional view of a prior art atomizing device; fig. 3 is a cross-sectional view of a prior art atomizing device.

In particular, fig. 1-3 illustrate a prior art heat generating face down atomizing device. "heating face down" refers to the orientation shown in the figures. In particular, "heat generating face down" means that the surface of the heat generating core (heat generating material) at which the atomizing medium is atomized faces down; more specifically, it refers to the orientation of the heat-generating surface such that the heated, atomized aerosol is ejected downward from the heating surface with respect to the device. In a "heating face down" arrangement, the aerosol exits the spray/exit heating face in a direction opposite to the direction in which the aerosol passes through the device to be inhaled by the user (i.e. "turns 180 degrees"). In particular, the term "heat generating surface" in the present invention covers a substantially downward state. That is, in the case of "heat generating face down", the heat generating faces are in a "parallel" orientation in the figure, while the present application covers the case where the heat generating faces are not parallel. The present invention is applicable to a case where the angle of the direction in which the aerosol is ejected from the heat generating surface and the direction in which the aerosol passes through the device to be sucked by the user is greater than 90 degrees.

As best illustrated in the cross-sectional view of the prior art atomizing device shown in fig. 3, the heat generating surface produces a downward aerosol jet F1 and causes a generally upward aerosol flow F2 under the influence of user suction, the aerosol flow F2 being susceptible to forming a vortex V inside the device, particularly where a localized enclosure (e.g., corner) is formed during upward travel. Such a vortex V forms a local circulation of the aerosol, which in the region where the vortex V is generated is liable to cause condensation of the aerosol and accumulation of the condensed aerosol. Condensation of aerosols and accumulation of condensed aerosols wastes atomized liquid and reduces the user's aspiration experience; at the same time, condensed liquid collected can erode electrical components in the device, causing damage to the device; furthermore, in the case where the device body is made of transparent and translucent materials, condensation of the aerosol and accumulation of the condensed aerosol visually appear as stains, and the visual effect is not beautiful.

The present invention proposes an atomizing unit assembly and an atomizing device comprising the same, which aim to solve the above-mentioned problems occurring in the prior art atomizing solutions with a heating surface facing downwards.

Referring to fig. 4-5, there are perspective and front views of an atomizing device according to some embodiments of the present disclosure.

As shown, an atomizing device according to some embodiments of the present application includes a nozzle unit 1, a body unit 2 connected to the nozzle unit, and a base assembly connected to the body unit. In some embodiments, the nozzle unit 1 and the main body unit 2 may be integrally formed. The mouthpiece unit 1 comprises a mouthpiece, which is a means for contact with the lips of a user, in any shape suitable for engagement with the lips of a user to draw aerosol generated by the atomizing unit assembly/atomizing device, e.g. cylindrical, tapered cylindrical with cut-out, cylindrical with flattened part, flattened shape, etc. The present application encompasses any shape that is shaped to engage the lips of a user to draw an aerosol. It will be readily appreciated that the mouthpiece unit 1 defines an aerosol passage therethrough which leads to an air outlet through which aerosol is inhaled by a user. The body unit 2 may be an elongated body comprising a longitudinal axis, and may be circular or elliptical in cross-section, or may be flat.

The body unit 2 defines in part an nebulized medium storage space and is configured for mounting a nebulized unit assembly therein. The body unit 2 may be partially or entirely made of a transparent or translucent material, or may be made of an opaque material. Transparent or translucent or opaque materials from which the body unit 2 is made are well known in the art and will not be described in detail herein.

The atomizing device of the present disclosure is described in further detail with reference to fig. 6-7, wherein fig. 6 is a cross-sectional view (taken along line A-A of fig. 4) of an atomizing device according to some embodiments of the present disclosure; fig. 7 is a cross-sectional view (taken along line B-B of fig. 4) of an atomizing device according to some embodiments of the present disclosure.

As illustrated in fig. 6-7, the body unit 2 includes an aerosolized media cartridge assembly 21, the aerosolized media cartridge assembly 21 and a cradle 22 of the aerosolized unit assembly described below partially defining an aerosolized media storage space for storing aerosolized liquid or aerosolized media (aerosolized liquid and aerosolized media are used interchangeably herein). A vertical air tube is arranged in the main body unit 2, and the air tube defines an aerosol channel; when the mouthpiece unit 1 is mounted on the body unit 2, i.e. when the mouthpiece unit 1 and the body unit 2 are connected to each other, the aerosol channels in the air tube are in fluid communication or alignment with the aerosol channels in the mouthpiece unit 1. The air tube may be integrally formed with the body unit 2 or may be a separate element. The trachea may be centrally located relative to the body unit 2 (with its central axis coinciding with the longitudinal axis of the body unit), in which case the trachea may be referred to as the central trachea. The air tube may also be non-centrally located, with its central axis not coincident with the longitudinal axis of the body unit. One end of the air tube interfaces (connects and forms an airtight seal) with an aerosol discharge port on a holder 22 of an atomizing unit assembly, described below, so that aerosol directed from the aerosol discharge port of the atomizing unit assembly passes through an aerosol passage in the air tube and thus through an aerosol passage in the mouthpiece unit.

The nebulized media cartridge assembly 21 and the mount 22 of the nebulizing unit assembly partially define a nebulized media storage space. More specifically, as shown in the drawing, the inner wall of the main body unit 2, the outer wall of the air tube, and an end surface of the holder 22 described below, which is provided with an aerosol discharge port, partially define an atomized medium storage space. The main body unit 2 is provided with a liquid filling port and a liquid filling plug for blocking the liquid filling port at one end, preferably at one end connected to the suction nozzle unit 1. The atomized medium/atomized liquid can be injected into the atomized medium storage space through the liquid injection port, so that the atomized medium is filled/recharged/replenished.

The atomizing unit assembly 23 may be partially or safely installed in the main body unit 2. The atomizing unit assembly 23 includes a holder 22, a heat generating core assembly, and an electrode assembly. The support 22 is preferably made of an opaque material. The holder 22 is mounted in the body unit 2 in a form-fitting manner, i.e. the holder 22 and the body unit 2 have the same outer contour in a direction perpendicular to the longitudinal axis, but differ in size. The holder 22 has a longitudinal axis and has walls defining an interior space of the holder 22. The heating core assembly is assembled in the inner space of the support 22 and is abutted against the electrode assembly, wherein the heating core assembly comprises a heating surface for heating and atomizing an atomization medium and generating aerosol; the electrode assembly is used for supplying power to the heating core assembly. The holder 22 of the atomizing unit assembly 23 is provided with a liquid inlet channel 214, see fig. 7-8. In particular, the holder 22 is fitted in the body unit 2 in such a way that its outer wall forms a liquid-tight seal with the inner wall of the body unit 2 and that an aerosol discharge opening provided in the holder 22 is in abutment with the air tube, whereby the end surfaces of the nebulization media cartridge assembly 21, the air tube and the holder surrounding the aerosol discharge opening define a nebulization media cartridge. The end face of the holder 22 of the atomizing unit assembly 23 around the aerosol discharge port of the holder is provided with a liquid inlet passage 214, thereby allowing the medium to be atomized in the atomized medium reservoir to be introduced into the holder 22 and brought into contact with the heat generating core assembly 232. The atomizing medium is atomized at the atomizing face of the wick assembly 232 and generates an aerosol that is sprayed downwardly into the atomizing chamber 215, as shown in fig. 9.

It follows that the holder 22 has a longitudinal axis with an aerosol discharge opening that interfaces with the air tube, the end surface of the holder 22 surrounding the aerosol discharge opening defining with (the inner wall of) the nebulized medium cartridge assembly 21, the (outer wall of the) air tube an nebulized medium storage space for accommodating the medium to be nebulized. For this purpose, the gas tube is connected/docked to the aerosol discharge opening and forms a gas-liquid seal, preferably by means of a sealing member, such as an O-ring, and also forms a liquid-tight seal between the outer wall of the holder and the inner wall of the body unit 2, preferably also by means of a sealing member, such as an O-ring, preferably mounted in a groove provided in the outer wall of the holder 22 (as shown in figures 6-11 and 12-16, etc.). In addition, the end face around the aerosol discharge port on the frame 22 is further provided with a liquid inlet channel 214 for allowing the atomized medium in the atomized medium storage space to enter the inside of the frame, more specifically, the inside of the frame to contact with the heating core assembly 232 inside the mounting frame, more specifically, the heating surface of the heating core assembly 232, so as to be heated and atomized, thereby generating the aerosol entering the atomizing chamber 215. The atomizing core assembly or the heating core assembly for atomizing an atomized liquid/atomized medium to generate an aerosol includes an atomizing core holder, a liquid guiding rod, an atomizing core, etc., which are well known in the art and are not described herein.

The holder 22 includes, in addition to defining an inner space in which the heat generating core assembly is fitted, a wall having a thickness defining the inner space, inside which at least one air flow channel 2313 (see fig. 10) is opened. The airflow passage communicates the atomizing chamber 215 with an aerosol discharge port that interfaces with the air tube to direct atomized aerosol within the atomizing chamber to exit the aerosol discharge port through the airflow passage to enter the air tube.

Further description is made with reference to fig. 10-11. The suction nozzle unit 1 and the main body unit 2 are connected in the above manner, and the components such as the holder 22, the heat generating core assembly 232, etc. are mounted in the main body unit 2 in the above manner, at least one air flow channel 2313 is opened in the wall of the holder 22, and at least one air intake hole (e.g., the first air intake hole 301 and/or the second air intake hole 302) is opened in the base assembly that is docked/connected with the main body unit 2. The medium/atomized liquid to be atomized in the atomized medium compartment enters the interior space defined by the holder 22 through at least one liquid inlet channel 214 opened on the end surface of the holder 22 and contacts a heater core assembly 232 installed in the interior space, and is heated by the atomizing surface of the heater core assembly 232 to generate aerosol (shown by downward arrows) sprayed toward the atomizing chamber 215. When the user is in use, negative pressure is formed by sucking at the air outlet 11 of the suction nozzle, so that external air enters the atomizing chamber 215 from, for example, the first air inlet hole 301 and/or the second air inlet hole 302, and the atomized aerosol is carried away from the atomizing chamber 215 via the air flow channel 2313, reaches the aerosol outlet opening formed in the bracket 22 and enters the air pipe, reaches the suction nozzle unit 1 via the air passage of the air pipe, reaches the air outlet 11 of the suction nozzle via the air passage in the suction nozzle unit 1, and is sucked by the user.

FIG. 9 also shows an electrode assembly in abutment with the heater core assembly 232, the heater core assembly 232 and the electrode assembly partially defining an atomization chamber; in an embodiment wherein the atomizing device further comprises a base assembly, the heat generating core assembly, and the electrode assembly define an atomizing chamber, and one or more air inlets are provided in the base for introducing external air. The electrode assembly includes positive and negative electrodes (pins) and optionally includes an electrode mount through which the (metal) electrode passes. The electrode assembly may be partially mounted in the holder 22 and may be connected to an external power source (e.g., a battery module) through an electrical connection structure in the base assembly. In some embodiments, the base assembly is a threaded sleeve adapted for use with the 510 interface.

As shown in the figure, the main body unit 2 comprises an atomized medium bin assembly 21, and the atomized medium bin assembly 21 is provided with a liquid injection port 212. The body unit 2 includes an integrally formed air tube. The main body unit 2 includes a mounting port 213 at an end connected to the nozzle unit 1, and the atomizing unit assembly 23 is fitted into the main body unit 2 from the mounting port 213. As shown, the air tube and aerosol discharge port will be connected (docked) by a first seal member seal 2211 (e.g., a sealing ring or O-ring) to form an airtight seal. The atomizing core assembly is fitted in the inner space defined by the bracket 22, and an electrode assembly including an electrode mount is also partially mounted in the inner space, the electrode assembly being abutted/connected with the atomizing core assembly.

Fig. 13 is a cross-sectional view of an installed atomizing device according to some embodiments of the present disclosure. As shown, the air tube interfaces with the aerosol discharge port via a first seal 2211 and the outer wall of the holder 22 forms a fluid tight seal with the inner wall of the body unit 2 via a second seal, in particular the second seal is mounted in a groove provided on the outer wall of the holder. The atomizing device further comprises a base assembly 24 connected to the main unit 2, wherein an electrical connection of the electrodes to an external power source is formed and at least one air inlet hole is provided.

It is clear from this figure how the air flow channels defined in the walls of the holder communicate with the atomizing chamber and the aerosol discharge opening and the central tube.

Figures 15 and 17 show different cross-sectional shapes of the air flow channels in the walls of the rack. In particular, the airflow passage is in the shape of a straight line, an arch, or an S-shape, etc., as viewed in a plane passing through the longitudinal axis of the main body unit and/or the holder and passing through the airflow passage, but is not limited thereto, and any cross-sectional shape of the airflow passage may be applicable to the present invention as long as it is provided in the wall of the holder and configured to communicate with the atomizing chamber and the aerosol discharge port.

Fig. 15-17 show different configurations of the end face of the holder, on which the aerosol discharge opening is provided, with respect to the longitudinal axis, in particular the end face may be at right, acute or obtuse angles with respect to the longitudinal axis. I.e. with reference to the orientation and orientation of the drawing, the end surface may be parallel to or angled with respect to the liquid surface of the nebulized media contained in the nebulized media cartridge.

As described above, the configuration of the airflow channel arranged in the wall of the bracket also reduces, even eliminates, vortex flow of the atomized gas in the atomizing device in the process of leading to the aerosol discharge outlet, thereby reducing condensate generation, improving user experience and increasing the utilization rate of atomized media, reducing the possibility of condensate accumulation and corrosion of circuits/electronic components in the device, and prolonging the service life of the device. To further mitigate the negative effects of condensate, in some embodiments, as shown in fig. 18, a trough (condensate collection trough) is formed on the side wall of the airflow channel 2313 for collecting the condensed atomizing medium. In some embodiments, the slot is defined by a protrusion protruding from a sidewall defining the airflow channel. In some embodiments, the groove extends helically or circumferentially relative to the longitudinal axis of the stent or body unit.

Also, in some embodiments, a wicking member, such as a nonwoven, is also provided in the device for further absorption of condensate and/or leakage (possibly non-atomized medium introduced into the interior space of the holder). As shown in fig. 19, the liquid absorbing member 29 is provided between the electrode assembly 233 and the base assembly, and can prevent the liquid from flowing into the air intake holes and/or from flowing out to other electric components to cause corrosion of electric connection, etc. Fig. 19 also shows a second seal, such as an O-ring, forming a fluid tight seal between the holder and the body unit.
