Patent Description:
Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since the aerosol is absorbable by the human body through the respiratory system, a novel alternative absorption manner is provided for the user. For example, atomizing devices that can generate aerosols by baking and heating herbal or paste-like aerosol-forming substrates are applied to different fields, to deliver inhalable aerosols for the users, leading to replacement of conventional product forms and absorption manners.

Generally, an electronic atomizing device heats and vaporizes the aerosol-forming substrate through an atomizer. However, an air inlet of the atomizer is provided on a bottom surface, condensate may be formed when the aerosol inside the atomizer flows back, and the condensate is likely to overflow from the air inlet under the action of its own gravity, resulting in corrosion damage to electronic components such as a cell at the bottom of the atomizer. In addition, the internal airway of a conventional atomizer is relatively long, and the inner wall of the airway provides a relatively long bearing surface for aerosol that flows back, which is likely to result in formation of more condensate. Therefore, the conventional atomizer is prone to formation of a large amount of condensate that overflows. Related technologies are known from <CIT>, <CIT>, and <CIT>.

In view of this, it is necessary to provide an atomizer and an electronic atomizing device to resolve the problem that the conventional atomizer is prone to formation of a large amount of condensate that overflows.

An atomizer is provided, including: a housing, wherein an air outlet channel is formed in the housing; and an atomizing assembly assembled in the housing and including a base and an atomizing core inserted in the base, wherein the base includes a top wall facing the air outlet channel and a side wall intersecting with and connected to the top wall; wherein an atomizing channel in communication with the air outlet channel is defined between the side wall and the atomizing core, the atomizing channel is located in an axial direction of the air outlet channel, and an air inlet in communication with the atomizing channel is provided on the side wall.

In the foregoing atomizer, the atomizing channel is defined between the side wall of the base and the atomizing core, and the atomizing channel is located in the axial direction of the air outlet channel, so that external air directly enters the atomizing channel through the air inlet on the side wall and then can enter the air outlet channel in the axial direction of the air outlet channel, which is equivalent to that an airflow pathway inside the atomizer is L-shaped, and the pathway is relatively simple and short. Therefore, the problem that the airflow pathway is excessively long and absorbs a large amount of aerosol and generates a large amount of condensate is avoided, thereby reducing the generated condensate. In addition, the air inlet of the atomizer is located on the side wall of the base rather than a bottom wall of the base, so that condensate generated in an internal airway may not directly flow out through the air inlet on the side wall, thereby preventing the leakage of the condensate.

In this way, the atomizer provided by this application not only can prevent condensate from leaking through the air inlet, but also can prevent generation of excessive condensate, thereby reducing the risk of the overflow of the condensate and reducing the amount of condensate leaking from the atomizer. In addition, the airflow pathway inside the atomizer provided by this application is relatively short, so that an external airflow can quickly enter the atomizing channel to carry the atomized aerosol, thereby improving the atomizing amount of the aerosol-forming substrate.

In an embodiment, the atomizing core includes an atomizing surface parallel to the axial direction of the air outlet channel, the atomizing surface is relatively spaced apart from the side wall, and the atomizing channel is defined between the atomizing surface and the side wall.

In an embodiment, the air inlet directly faces the atomizing surface.

In an embodiment, the atomizing assembly further includes an electrode, one end of the electrode is electrically connected to a heating member on the atomizing core, and the other end of the electrode penetrates through the side wall and is relatively exposed on an outer surface of the side wall.

In an embodiment, the electrode penetrates through the side wall in a direction intersecting with the axial direction of the air outlet channel.

In an embodiment, a docking cavity is defined between the housing and the outer surface of the side wall, where the docking cavity is configured to accommodate a docking convex portion of a cell base.

In an embodiment, the base includes a base body and a holder, the atomizing core and the holder are both inserted in the base body, one end of the holder abuts against the atomizing core, the other end of the holder is the side wall and is provided with the air inlet, and the electrode fixedly penetrates through the end of the holder provided with the air inlet.

In an embodiment, the atomizing core includes a liquid absorbing surface away from the atomizing surface, a liquid storage cavity is formed inside the housing, a liquid inlet channel in communication with the liquid storage cavity is provided on the base body, and the liquid absorbing surface is in fluid communication with the liquid inlet channel.

In an embodiment, the liquid storage cavity surrounds a periphery of the air outlet channel, and the liquid inlet channel is located on a surface of the atomizing core away from the air inlet and extends in a direction parallel to the axial direction of the air outlet channel.

In an embodiment, the atomizer further includes a magnetic member, the base includes a bottom wall opposite to the top wall, and the magnetic member is assembled on the bottom wall.

An electronic atomizing device is provided including the foregoing atomizer.

<FIG> is a cross-sectional view of an atomizer according to an embodiment of the present invention. Referring to <FIG>, an embodiment of the present invention provides an atomizer <NUM>, which is configured to heat and atomize an aerosol-forming substrate to form aerosol delivered to a user.

The atomizer <NUM> includes a housing <NUM> and an atomizing assembly <NUM>. An air outlet channel <NUM> is formed in the housing <NUM>. The atomizing assembly <NUM> is assembled in the housing <NUM> and includes a base <NUM> and an atomizing core <NUM> inserted in the base <NUM>.

The base <NUM> includes a top wall <NUM> facing the air outlet channel <NUM> and a side wall <NUM> intersecting with and connected to the top wall <NUM>. An atomizing channel <NUM> in communication with the air outlet channel <NUM> is defined between the side wall <NUM> of the base <NUM> and the atomizing core <NUM>. The atomizing channel <NUM> is located in an axial direction of the air outlet channel <NUM>, and an air inlet <NUM> in communication with the atomizing channel <NUM> is provided on the side wall <NUM>. During operation of the atomizer <NUM>, an aerosol-forming substrate is adsorbed in the atomizing core <NUM>, and after the atomizing core <NUM> is heated, the aerosol-forming substrate is atomized into aerosol and enters the atomizing channel <NUM>. Then an airflow entered from the air inlet <NUM> flows through the atomizing channel <NUM>, and carries the aerosol to flow out of the air outlet channel <NUM>, so as to deliver the atomized aerosol to the user.

In this embodiment, the atomizing channel <NUM> is defined between the side wall <NUM> of the base <NUM> and the atomizing core <NUM>, and the atomizing channel <NUM> is located in the axial direction of the air outlet channel <NUM>, so that external air directly enters the atomizing channel <NUM> through the air inlet <NUM> on the side wall <NUM> and then can enter the air outlet channel <NUM> in the axial direction of the air outlet channel <NUM>, which is equivalent to that an airflow pathway inside the atomizer <NUM> is L-shaped, and the pathway is relatively simple and short. Therefore, the problem that the airflow pathway is excessively long and absorbs a large amount of aerosol and generates a large amount of condensate is avoided, thereby reducing the generated condensate. In addition, the air inlet <NUM> of the atomizer <NUM> is located on the side wall <NUM> of the base <NUM> rather than a bottom wall <NUM> of the base <NUM>, so that condensate generated in an internal airway may not directly flow out through the air inlet <NUM> on the side wall, thereby preventing the leakage of the condensate.

In this way, the atomizer <NUM> provided by this embodiment not only can prevent condensate from leaking through the air inlet <NUM>, but also can prevent generation of excessive condensate, thereby reducing the risk of the leakage of the condensate, and reducing the amount of condensate leaking from the atomizer <NUM>. In addition, the airflow pathway inside the atomizer <NUM> provided in this application is relatively short, so that an external airflow can quickly enter the atomizing channel <NUM> to carry the atomized aerosol, thereby improving the atomizing amount of the aerosol-forming substrate.

Further, the atomizing core <NUM> includes an atomizing surface <NUM> parallel to the axial direction of the air outlet channel <NUM>, that is, the atomizing core <NUM> is laterally arranged. The atomizing surface <NUM> is relatively spaced apart from the side wall <NUM>, and the atomizing channel <NUM> is defined between the atomizing surface <NUM> and the side wall <NUM>, so that the formed atomizing channel <NUM> has a linear shape with a simple structure and a short pathway, thereby reducing the formation of condensate while improving the atomizing amount of the aerosol-forming substrate.

Specifically, the air inlet <NUM> provided on the side wall <NUM> directly faces the atomizing surface <NUM>, so that the air inlet <NUM> is in direct communication with the atomizing channel <NUM> between the side wall <NUM> and the atomizing surface <NUM>, and air flowing in an axial direction of the air inlet <NUM> can directly enter the atomizing channel <NUM> without making a turn before entering the atomizing channel <NUM>, thereby shortening the airflow pathway.

In some embodiments, the atomizing assembly <NUM> further includes an electrode <NUM>. The atomizing core <NUM> further includes a heating member. One end of the electrode <NUM> is electrically connected to the heating member, and the other end of the electrode <NUM> penetrates through the side wall <NUM> and is relatively exposed on an outer surface of the side wall <NUM>. It is equivalent to that, not only the air inlet <NUM> is provided on the side wall <NUM> of the base <NUM>, but also the electrode <NUM> penetrates through the side wall <NUM>, so that the electrode <NUM> is fixedly mounted through the side wall <NUM>. In addition, the electrode <NUM> is relatively exposed on the outer surface of the side wall <NUM>, so that the electrode <NUM> can be used as a docking end of the heating member of the atomizing core <NUM> and that is electrically connected to a cell base <NUM>. Therefore, the docking end has a specific area, even if there is a slight relative displacement between the atomizer <NUM> and the cell base <NUM> in a mounting direction, the electrical contact between the electrode <NUM> on the side wall <NUM> and the cell base <NUM> can be ensured, thereby improving the stability of power supply.

Further, the electrode <NUM> penetrates through the side wall <NUM> in a direction intersecting with the axial direction of the air outlet channel <NUM>, that is, the electrode <NUM> is laterally arranged. In this way, after the atomizer <NUM> and the cell base <NUM> are vertically mounted in a docked manner, the laterally arranged electrode <NUM> may still be in electrical contact with the cell base <NUM> on the outer surface of the side wall <NUM>, even if the cell base <NUM> is slightly misaligned with the atomizer <NUM> in the mounting direction.

In some embodiments, a docking cavity <NUM> is defined between the housing <NUM> and the outer surface of the side wall <NUM>, and the docking cavity <NUM> is configured to accommodate a docking convex portion <NUM> on the cell base <NUM>. During assembly of the atomizer <NUM> and the cell base <NUM>, the docking convex portion <NUM> on the cell base <NUM> is inserted into the docking cavity <NUM>, so that the electrode <NUM> relatively exposed on the outer surface of the side wall <NUM> can be in electrical contact with a docking terminal on the docking convex portion <NUM> through the docking cavity <NUM>, thereby achieving the electrical connection between the heating member on the atomizing core <NUM> and the cell base <NUM>. In addition, the docking cavity <NUM> accommodates the docking convex portion <NUM> to limit the docking convex portion <NUM>, so that the docking convex portion <NUM> is prevented from being separated from the side wall <NUM>, thereby ensuring that the electrode <NUM> is electrically connected to the cell base <NUM> effectively after the docking convex portion <NUM> comes in contact with the side wall <NUM>, and further improving the reliability of power supply.

Specifically, the docking cavity <NUM> can limit the docking convex portion <NUM> in a first direction perpendicular to the air outlet channel <NUM> and a second direction perpendicular to the first direction, so as to prevent the docking convex portion <NUM> from being displaced in the thickness and width directions of the atomizer <NUM> and improve the reliability of contact between the docking convex portion <NUM> and the side wall <NUM>, thereby improving the user experience.

In addition, an end of the holder <NUM> away from the atomizing core <NUM> is constructed as the side wall <NUM> and is provided with the air inlet <NUM>, so that the atomizing channel <NUM> is formed between the holder <NUM> and the atomizing core <NUM>. Moreover, the holder <NUM> is configured to fix a cell on the base <NUM>.

Further, an air passing opening <NUM> in communication with the atomizing channel <NUM> and the air outlet channel <NUM> is provided on the base body <NUM>, so as to allow airflow to flow from the atomizing channel <NUM> to the air outlet channel <NUM>. In addition, a through groove in communication with the atomizing channel <NUM> and the air passing opening <NUM> is formed on the holder <NUM>, so that the electrode <NUM> can be assembled through the holder <NUM> without affecting the communication between the atomizing channel <NUM> between the holder <NUM> and the atomizing core <NUM> and the air outlet channel <NUM>.

Referring to <FIG>, specifically, the atomizing core <NUM> includes a liquid absorbing surface <NUM> away from the atomizing surface <NUM>.

In addition, when the atomizing core <NUM> is normally held by the user, the liquid inlet channel <NUM> extends in a vertical direction, and the aerosol-forming substrate in the liquid storage cavity <NUM> is allowed to be in contact with the liquid absorbing surface <NUM> of the atomizing core <NUM> after flowing toward the liquid inlet channel <NUM>.

In some embodiments, the housing <NUM> includes an outer housing <NUM> and an inner housing <NUM> inserted in the outer housing <NUM>. The inner housing <NUM> has the air outlet channel <NUM>, and the liquid storage cavity <NUM> is defined between the inner housing <NUM> and the outer housing <NUM>.

<FIG> is a cross-sectional view of an electronic atomizing device <NUM> according to an embodiment of the present invention. Referring to <FIG>, the electronic atomizing device <NUM> includes the atomizer <NUM>. The atomizer <NUM> includes a housing <NUM> and an atomizing assembly <NUM>. An air outlet channel <NUM> is formed in the housing <NUM>. The atomizing assembly <NUM> is assembled in the housing <NUM> and includes a base <NUM> and an atomizing core <NUM> inserted in the base <NUM>. The base <NUM> includes a top wall <NUM> facing the air outlet channel <NUM> and a side wall <NUM> intersecting with and connected to the top wall <NUM>. An atomizing channel <NUM> in communication with the air outlet channel <NUM> is defined between the side wall <NUM> of the base <NUM> and the atomizing core <NUM>, the atomizing channel <NUM> is located in an axial direction of the air outlet channel <NUM>, and an air inlet <NUM> in communication with the atomizing channel <NUM> is provided on the side wall <NUM>. In this way, the atomizing channel <NUM> is defined between the side wall <NUM> of the base <NUM> and the atomizing core <NUM>, and the atomizing channel <NUM> is located in the axial direction of the air outlet channel <NUM>, so that external air directly enters the atomizing channel <NUM> through the air inlet <NUM> on the side wall <NUM> and then can enter the air outlet channel <NUM> in the axial direction of the air outlet channel <NUM>, which is equivalent to that an airflow pathway inside the atomizer <NUM> is L-shaped, and the pathway is relatively simple and short, so that the airflow pathway is prevented from generating a large amount of condensate after absorbing a large amount of aerosol because of being excessively long, thereby reducing the formation of condensate.

In addition, the air inlet <NUM> of the atomizer <NUM> is located on the side wall <NUM> of the base <NUM> rather than a bottom wall <NUM> of the base <NUM>, so that condensate generated in an internal airway may not directly flow out through the air inlet <NUM> on the side wall, thereby preventing the leakage of the condensate. Therefore, the atomizer <NUM> provided in this embodiment not only can prevent condensate from leaking through the air inlet <NUM>, but also can prevent generation of excessive condensate, thereby reducing the risk of condensate leakage, and reducing the amount of condensate leaking from the atomizer <NUM>. In addition, the airflow pathway inside the atomizer <NUM> provided in this embodiment is relatively short, so that an external airflow can quickly enter into the atomizing channel <NUM> to carry the atomized aerosol, thereby improving the atomizing amount of the aerosol-forming substrate.

In some embodiments, the electronic atomizing device <NUM> further includes a cell base <NUM>. The cell base <NUM> includes a main body and a docking convex portion <NUM> protruding from the main body. The docking convex portion <NUM> includes a docking terminal, and the docking terminal can be in electrical contact with the electrode <NUM> when the docking convex portion <NUM> is docked with the side wall <NUM>, so as to achieve the electrical connection between the atomizer <NUM> and the cell base <NUM>.

Further, the docking cavity <NUM> is formed in the atomizer <NUM>, and the docking convex portion <NUM> is inserted in the docking cavity <NUM>. In this way, the docking cavity <NUM> accommodates the docking convex portion <NUM> to limit and fix the docking convex portion <NUM>, so that the docking convex portion <NUM> is prevented from being separated from the side wall <NUM>, thereby ensuring that the electrode <NUM> is electrically connected to the cell base <NUM> effectively after the docking convex portion <NUM> is in contact with the side wall <NUM>, and further improving the reliability of power supply.

Specifically, the docking cavity <NUM> limits the docking convex portion <NUM> in a first direction perpendicular to the air outlet channel <NUM> and a second direction perpendicular to the first direction, so as to prevent the docking convex portion <NUM> from being displaced in the thickness and width directions of the atomizer <NUM> and improve the reliability of contact between the docking convex portion <NUM> and the side wall <NUM>, thereby improving the user experience.

In some embodiments, an air inlet channel communicating between the outside and the air inlet <NUM> is formed inside the docking convex portion <NUM>, the external airflow passes through the air inlet channel in the docking convex portion <NUM> and then enters the air inlet <NUM> on the side wall <NUM>, and finally flows inside the atomizer <NUM>. In this way, air is supplied to the air inlet <NUM> through the docking convex portion <NUM>, thus achieving air intake from a side of the atomizer <NUM>. In addition, since the air inlet channel in the docking convex portion <NUM> is located on a side of the air inlet <NUM> rather than being located at the bottom of the air inlet <NUM>, when a part of the aerosol in the atomizer <NUM> flows back to form condensate, the condensate cannot easily enter the docking convex portion <NUM> on the side through the air inlet <NUM>, which can effectively prevent electronic components inside the cell base <NUM> from corrosion damage caused by the condensate, thereby prolonging the service life of the electronic atomizing device <NUM>.

However, provided that combinations of the technical features do not conflict with each other, the combinations of the technical features are considered as falling within the scope described in this specification.
