The atomization assembly <NUM> includes an atomizing core <NUM>, an air inlet <NUM>, and a fluid-guide member <NUM>. The atomizing core <NUM> is configured to atomize the aerosol-forming substrate, so as to form the aerosol. The atomizing core <NUM> includes an atomizing surface and a non- atomizing surface. The fluid-guide member <NUM> is disposed between the air inlet <NUM> and the atomizing core <NUM>. The fluid-guide member <NUM> and the air inlet <NUM> are arranged at intervals, and the fluid-guide member <NUM> shields a bottom surface of the atomizing core <NUM>, such that an air flow entering from the air inlet <NUM> may flow along a side surface of the fluid-guide member <NUM> to the atomizing surface of the atomizing core <NUM>. It should be appreciated that the bottom surface of the atomizing core <NUM> may be a surface of the atomizing core <NUM> close to the air inlet <NUM>, and the fluid-guide member <NUM> shields the bottom surface of the atomizing core <NUM>, thereby preventing the air flow entering from the air inlet <NUM> from directly blowing the atomizing core <NUM>. Furthermore, the fluid-guide member <NUM> may guide the air flow to flow along a side surface of the atomizing core <NUM> to a side where the atomizing surface of the atomizing core <NUM> is located.

In an embodiment, a projection of the atomizing core <NUM> on a plane where the fluid-guide member <NUM> is located is completely coincident with the fluid-guide member <NUM>, such that the fluid-guide member <NUM> may achieve a better shielding effect, thereby preventing the air flow from directly blowing the bottom surface of the atomizing core <NUM> as far as possible.

In an embodiment, the atomizing core <NUM> includes a porous liquid-guide member and a heating member. The heating member is disposed on a surface of the porous liquid-guide member. The porous liquid-guide member may guide the aerosol-forming substrate to the heating member, such that the aerosol-forming substrate may be atomized. In other words, a surface on which the porous liquid-guide member is arranged with the heat member is the atomizing surface, and other surfaces on which the porous liquid-guide member is not arranged with the heat member are the non-atomizing surface. The air inlet <NUM> is arranged to face towards the non-atomizing surface of the atomizing core <NUM>, thereby preventing the air flow entering from the air inlet <NUM> from directly blowing the atomizing core <NUM>. The fluid-guide member <NUM> is disposed between the air inlet <NUM> and the atomizing core <NUM>, and the fluid-guide member <NUM> may guide the air flow to flow along the side surface of the atomizing core <NUM> to the side where the atomizing surface of the atomizing core <NUM> is located, thereby further preventing the air flow entering from the air inlet <NUM> from directly blowing the non-atomizing surface of the atomizing core <NUM>. In other words, a relative position relationship of the atomizing core <NUM>, the air inlet <NUM>, and the fluid-guide member <NUM> makes it impossible for the air flow entering from the air inlet <NUM> to directly blow the atomizing core <NUM>, so as to prevent an temperature of the atomizing core <NUM> from being affected by the air flow, thereby preventing a heating efficiency of the atomizing core <NUM> from being affected by cool air, thus it is beneficial to ensure atomization amount of the atomizing assembly <NUM>, thus improving the user experience.

It should be appreciated that the atomizing surface of the atomizing core <NUM> may be an upper surface thereof, a bottom surface thereof, or a side surface thereof, which may be designed according to requirements. A setting manner of the air inlet <NUM> and the fluid-guide member <NUM> is in cooperation with a setting manner of the atomizing surface of the atomizing core <NUM>.

When the atomizing surface of the atomizing core <NUM> is the upper surface thereof, a structure of the atomizing assembly <NUM> is described in detail.

The atomizing assembly <NUM> further includes a housing <NUM> and an atomizing base <NUM>. An end of the housing <NUM> defines an inhaling port <NUM>, and a user inhales the aerosol atomized by the atomizing core <NUM> through the inhaling port <NUM>. The housing <NUM> forms a liquid storage cavity <NUM>, an air outlet channel <NUM>, and an accommodating cavity <NUM>. The air outlet channel <NUM> is in communication with the inhaling port <NUM>. The liquid storage cavity <NUM> is wound on the air outlet channel <NUM>. The accommodating cavity <NUM> is disposed a side of the liquid storage cavity <NUM> away from the inhaling port <NUM>. The atomizing core <NUM>, the atomizing base <NUM>, and the fluid-guide member <NUM> are disposed in the accommodating cavity <NUM>. In other words, the atomizing core <NUM>, the atomizing base <NUM>, and the fluid-guide member <NUM> are disposed in the housing <NUM>. The air inlet <NUM> is disposed on a side of the atomizing base <NUM> away from the inhaling port <NUM>.

In an embodiment, the atomizing base <NUM> defines an installation cavity <NUM>. The atomizing core <NUM> is disposed in the installation cavity <NUM>. The atomizing core <NUM> and the atomizing base <NUM> are disposed in the accommodating cavity <NUM>. The atomizing surface of the atomizing core <NUM> faces towards the inhaling port <NUM>. An atomization cavity <NUM> is defined between the atomizing surface of the atomizing core <NUM> and a top wall of the installation cavity <NUM>. The atomization cavity <NUM> is in communication with the air outlet channel <NUM>, such that the aerosol atomized by the atomizing core <NUM> may pass through the atomization cavity <NUM>, the air outlet channel <NUM>, and the inhaling port <NUM>, and the aerosol may be inhaled by the users.

The atomizing base <NUM> is further arranged with two liquid channels <NUM>. The two liquid channels <NUM> are symmetrically arranged on two sides of the air outlet channel <NUM>. One end of the liquid channel <NUM> is in communication with the liquid storage cavity <NUM>, and the other end of the liquid channel <NUM> is connected to the atomizing core <NUM>, such that it is possible that the atomizing core <NUM> atomizes the aerosol-forming substrate stored in the liquid storage cavity <NUM>. The atomizing core <NUM> further includes a first side surface and a second side surface disposed opposite to each other. The atomizing core <NUM> further includes a third side surface and a fourth side surface, and the third side surface and the fourth side surface are connected to the first side surface and the second side surface. Since the atomizing surface of the atomizing core <NUM> is arranged to face towards the inhaling port <NUM>, the other ends of the two liquid channels <NUM> are respectively connected to the first side surface and the second side surface of the atomizing core <NUM>. The fluid-guide member <NUM> is disposed on a side of the atomizing core <NUM> away from the inhaling port <NUM>, and is configured to guide the air flow to flow along the third side surface and the fourth side surface of the atomizing core <NUM> to the side where the atomizing surface of the atomizing core <NUM> is located. In other words, the fluid-guide member <NUM> guides the air flow to flow along two sides of the atomizing core <NUM> to the side where the atomizing surface of the atomizing core <NUM> is located.

Each of two opposite side surfaces of the atomizing base <NUM> and the housing <NUM> defines a gas-guide channel <NUM>. One end of the gas-guide channel <NUM> is in communication with the air inlet <NUM>, and the other end of the gas-guide channel <NUM> is in communication with the atomization cavity <NUM> (as shown in <FIG>). The gas-guide channel <NUM> is arranged to achieve the air flow to flow along the two sides of the atomizing core <NUM> to the side where the atomizing surface of the atomizing core <NUM> is located. When the user inhales the aerosol, a viscosity of the aerosol-forming substrate decreases as the temperature rises, and some of the aerosol-forming substrate hang on a surface of the atomizing core <NUM>. In this case, when a high-speed air flow passes through the surface of the atomization core <NUM>, the aerosol-forming substrate hanging on the surface of the atomizing core <NUM> is carried to the air outlet channel <NUM> by the high-speed air flow, thus there is a risk of liquid leakage. In some embodiments according to the present disclosure, the fluid-guide member <NUM> is disposed on the side of the atomizing core <NUM> away from the inhaling port <NUM>, thereby preventing the high-speed air flow from directly blowing the atomizing core <NUM>, thus the high-speed air flow may blow a surface of the fluid-guide member <NUM>, be guided by the fluid-guide member <NUM>, and enter from the gas-guide channel <NUM> disposed on the two opposite sides of the atomizing base <NUM> into the atomization cavity <NUM>. The atomizing core <NUM> is arranged to be disposed in the installation cavity <NUM> defined by the atomizing base <NUM>, thereby preventing the air flow passing through the surface of the atomizing core <NUM>, thus a phenomenon of a leak of liquid when the user inhales the aerosol is reduced.

The atomizing base <NUM> includes an atomizing top base <NUM> and an atomizing bottom base <NUM>. The atomizing bottom base <NUM> is disposed on a side of the atomizing top base <NUM> away from the inhaling port <NUM>, and the fluid-guide member <NUM> is disposed between the atomizing top base <NUM> and the atomizing bottom base <NUM>. The fluid-guide member <NUM> is arranged with a first connection structure, the atomizing top base <NUM> and/or the atomizing bottom base <NUM> is arranged with a second connection structure, and the first connection structure are arranged in cooperation with the second connection structure, such that the fluid-guide member <NUM> may be fixed on the atomizing top base <NUM> and/or the atomizing bottom base <NUM>. In an embodiment, the fluid-guide member <NUM> defines an insert-connection hole <NUM>, and the atomizing top base <NUM> is arranged with an insert-connection member <NUM>. The insert-connection member <NUM> is inserted into the insert-connection hole <NUM>, such that the fluid-guide member <NUM> may be fixed on the atomizing base <NUM> (as shown in <FIG>).

The atomizing bottom base <NUM> defines the air inlet <NUM>, the air inlet <NUM> and the fluid-guide member <NUM> are arranged at intervals, and the fluid-guide member <NUM> shields the air inlet <NUM>. In an embodiment, a side of the fluid-guide member <NUM> is exposed on the accommodating cavity <NUM> by the atomizing base <NUM>, and the side of the fluid-guide member <NUM> and the housing <NUM> are arranged at intervals, such that the air flow entering from the air inlet <NUM> may enter into the gas-guide channel <NUM> through a gap between the fluid-guide member <NUM> and the housing <NUM>, thereby entering the atomization cavity <NUM>. In another embodiment, the side of the fluid-guide member <NUM> is exposed on the accommodating cavity <NUM> by the atomizing base <NUM>, each of two opposite sides of the fluid-guide member <NUM> define a communication opening <NUM>, such that the air flow entering from the air inlet <NUM> may enter into the gas-guide channel <NUM> through the communication opening <NUM>, and flow to the atomizing surface of the atomizing core <NUM>, thereby entering the atomization cavity <NUM> (as shown in <FIG> and <FIG>). In other words, the gas-guide channel <NUM> is in communication with the air inlet <NUM> by the communication opening <NUM>. The communication opening <NUM> may be a through hole, or a notch, which is designed according to requirements.

In an embodiment, the atomizing base <NUM> includes a first surface and a second surface disposed opposite to each other. Each of the first surface and the second surface of the atomizing base <NUM> define a groove <NUM>. The groove <NUM> and a sidewall of the housing <NUM> cooperatively define the gas-guide channel <NUM> (as shown in <FIG>). One end of the groove <NUM> is in communication with each communication opening <NUM> of the fluid-guide member <NUM>, and the other end of the groove <NUM> is in communication with the atomization cavity <NUM>. The groove <NUM> is disposed on surfaces of the atomizing top base <NUM> and/or the atomizing bottom base <NUM>, which is designed according to requirements. It should be appreciated that the gas-guide channel <NUM> may be other structures, as long as it is possible to preventing the air flow from passing through the surface of the atomizing core <NUM>, which is designed according to requirements.

The atomization assembly <NUM> further includes a sealing member <NUM>, and the sealing member <NUM> is disposed between the side surface of the atomizing core <NUM> and a sidewall of the installation cavity <NUM> of the atomizing base <NUM>. In an embodiment, the sealing member <NUM> is only disposed on the side surface of the atomizing core <NUM>, and the fluid-guide member <NUM> is configured to cover a surface of the atomizing core <NUM> away from the inhaling port <NUM>, that is, the fluid-guide member <NUM> is configured to cover a surface of the atomizing core <NUM> away from the atomizing surface. The fluid-guide member <NUM> abuts against a side surface of the sealing member <NUM> close to the fluid-guide member <NUM>, so as to seal the atomizing core <NUM>, thereby reducing a possibility of the liquid leakage. In an embodiment, the fluid-guide member <NUM> is fitted with a surface of the atomizing core <NUM> away from the inhaling port <NUM>, such that the air flow entering from the air inlet <NUM> may be blocked by the fluid-guide member <NUM>, thereby reducing an impact of the air flow on the temperature of the atomizing core <NUM>. In another embodiment, a gap is defined between the fluid-guide member <NUM> and the surface of the atomizing core <NUM> away from the inhaling port <NUM>, such that air is configured to insulate heat, thereby further reducing the impact of the air flow entering from the air inlet <NUM> on the temperature of the atomizing core <NUM>.

The side surface of the atomizing core <NUM> is wrapped by the sealing member <NUM>, and a bottom of the atomizing core <NUM> is covered by the fluid-guide member <NUM>. That is to say, only the atomizing surface of the atomizing core <NUM> is exposed, and the gas-guide channel <NUM> is arranged to make the air flow blow to a top of the atomizing core <NUM>, and prevent the air flow from directly blowing the atomizing core <NUM>. In this way, when the aerosol is carried away by the air flow, it is possible to prevent the temperature from being reduced due to excessive air cooling, and result in the unnecessary heat loss, such that the atomizing core <NUM> may quickly perform a next atomization, thereby prolonging a boiling time of the aerosol-forming substrate, thus the atomization amount is increased, and the user's inhaling taste is improved. Materials of the sealing member <NUM> and the fluid-guide member <NUM> may be silica gel, plastic, or the like, preferably silica gel.

As shown in <FIG> and <FIG>, <FIG> is another partial schematic structural view of the electronic atomization device according to some embodiments of the present disclosure, and <FIG> is a schematic structural view of a guide member of the electronic atomization device viewed from another view angle.

One end of the lead <NUM> is connected to the atomizing core <NUM>, and the other end of the lead <NUM> is connected to the electrode pin <NUM>. The electrode pin <NUM> is connected to an electrical connection member of the battery assembly <NUM>, such that the atomization assembly <NUM> may be electrically connected to the battery assembly <NUM>.

A surface of the fluid-guide member <NUM> close to the air inlet <NUM> is arranged with a protrusion member <NUM>. The protrusion member <NUM> defines an opening <NUM>. One end of the electrode pin <NUM> is inserted in the opening <NUM>, and the other end of the electrode pin <NUM> is configured to connect to the battery assembly <NUM>. One end of the lead <NUM> is connected to the atomizing core <NUM>, and the other end of the lead <NUM> is disposed in the opening <NUM> and electrically connected to the electrode pin <NUM>.

The atomizing bottom base <NUM> defines an installation hole <NUM>. The protrusion member <NUM> is disposed in the installation hole <NUM>. The other end of the lead <NUM> passes through the opening <NUM>, and is bent and disposed between an inner surface of the installation hole <NUM> and an outer surface of the protrusion member <NUM>. In an embodiment, the opening <NUM> may be a blind hole, the lead <NUM> passes through a bottom wall of the opening <NUM>, enters into the opening <NUM>, and is fitted with an inner surface of the opening. In this case, the lead <NUM> passes through the opening <NUM>, and is bent and disposed in the installation hole <NUM> of the atomizing bottom base <NUM>, a setting manner of the lead <NUM> on the fluid-guide member <NUM> makes the lead <NUM> be closely contacted with the electrode pin <NUM>, such that it is possible to stabilize the communication with the battery assembly <NUM>. At the same time, the above design may prevent the lead <NUM> from penetrating the bottom of the atomizing bottom base <NUM>, and breaking an interference seal on the electrode pin <NUM>, such that it is possible to prevent the aerosol-forming substrate from flowing out along the lead <NUM>, thereby improving a performance of preventing a shelved liquid leakage.

The atomization assembly of the present disclosure includes the atomizing core, the air inlet, and the fluid-guide member. The fluid-guide member is disposed between the air inlet and the atomizing core. The fluid-guide member and the air inlet are arranged at intervals, and the fluid-guide member shields the bottom of the atomizing core. In this way, the fluid-guide member may prevent the cool air entering from the air inlet from directly blowing the atomizing core, such that it is possible to prevent the heating efficiency of the atomizing core from being affected by the cool air, thus it is beneficial to ensure the atomization amount of the atomizing assembly, thus improving the user experience.
