[0018] In some embodiments, the inner side wall of the airway member is provided with a third protrusion and a fourth protrusion;

[0019] The third protrusion is arranged along the axial direction of the airway member to guide the aerosol product to pass through the through hole; the fourth protrusion is arranged along the circumferential direction of the airway member to seal the aerosol product and the airway member.

[0020] In some embodiments, the housing assembly includes a top cover, a body, and a bottom shell;

[0021] The shell body is connected to the bottom shell and together encloses a accommodating cavity with an open end. The heating element is installed in the accommodating cavity.

[0040] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0041] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0042] The present application provides an atomizing device, such as Figure 1 and Figure 2 As shown, the atomizing device may include a housing 1, a power supply component 2 and an atomizer 100. The power supply component 2 may be disposed in the housing 1, the atomizer 100 may be electrically connected to the power supply component 2, and the power supply component 2 may supply power to the atomizer 100 so that the atomizer 100 heats the aerosol product 3 and generates an aerosol.

[0043] Among them, the housing 1 can be set to a box-shaped or long strip-shaped structural shape, the power supply component 2 can include electronic components such as a circuit board, a battery, and electrodes. The atomizer 100 can be electrically connected to the circuit board through the electrodes, and the circuit board can be electrically connected to the battery, so that the battery can power the atomizer 100. In other embodiments, the atomizer 100 can also be directly electrically connected to the battery. In addition, the power supply component 2 can also be set outside the housing 1, and the power supply component 2 can be detachably connected to the housing 1. This application does not impose any special restrictions on the specific structure of the housing 1 and the power supply component 2.

[0044] In order to avoid burns to the user during use, the present application also provides an atomizer 100, such as Figures 1 to 4 As shown, the atomizer 100 may include a shell assembly 11, a heating element 12 and an air duct member 13, the heating element 12 is connected to the shell assembly 11, the heating element 12 is provided with a heating cavity 124 with an open end, and the inner surface of the heating element 12 is provided with a first air duct 123; the air duct member 13 can be installed in the shell assembly 11, the air duct member 13 is provided with a through hole 131 connected to the heating cavity 124, and the aerosol product 3 can pass through the through hole 131 and be inserted into the heating cavity 124; a second air duct 132 connected to the outside is formed between the shell assembly 11 and the air duct member 13, and the second air duct 132 can have at least one bending section; wherein the first air duct 123 and the second air duct 132 are connected in the shell assembly 11, after the aerosol product 3 is inserted into the heating cavity 124, the external airflow can flow into the first air duct 123 along the second air duct 132, and after being heated by the heating element 12, a hot air flow is generated to heat the atomized aerosol product 3.

[0045] Since the second air duct 132 is connected to the outside, the first air duct 123 is connected to the second air duct 132, and the first air duct 123 is arranged on the inner surface of the heating element 12. When the user inhales, the external air flow can flow from the second air duct 132 into the first air duct 123, and the heating element 12 can preheat and then heat the external air flow, so that the heated hot air flow can atomize the aerosol product 3 to improve the efficiency of atomization. When the user stops inhaling, the hot air flow flows back from the first air duct 123 to the second air duct 132 under the action of atmospheric pressure. Since the second air duct 132 between the shell assembly 11 and the air duct member 13 has at least one bending section, the flow path of the hot air flow at the bending section position of the second air duct 132 is extended. Since the second air duct 132 is arranged at a position close to the external air flow, the hot air flow can be cooled in advance at the bending section position before flowing out of the second air duct 132, thereby reducing the temperature of the hot air flow when it is ejected to avoid scalding the user.

[0046] In addition, liquid impurities after the hot air flow is atomized usually remain in the air flow channel. In the present application, since the first air duct 123 is arranged on the inner surface of the heating element 12, the air duct member 13 is installed in the shell assembly 11 and forms a second air duct 132 arranged in the shell assembly 11 between the shell assembly 11, and the first air duct 123 and the second air duct 132 are connected in the shell assembly 11, so that the entire air flow channel is located inside the shell assembly 11 and the heating element 12. The liquid impurities after the hot air flow is atomized will be contained in the shell assembly 11 and the heating element 12, and will not flow into the interior of the atomizing device to pollute the atomizing device. Therefore, the atomizer 100 provided in the present application can not only avoid scalding the user, but also facilitate the user to clean up the liquid impurities to avoid blockage of the air flow channel.

[0047] Among them, the first air duct 123 can be an open channel arranged on the inner surface of the heating element 12, or it can be a closed channel arranged on the inner surface of the heating element 12. The second air duct 132 can be an open channel that is partially arranged on the shell assembly 11 and partially arranged on the air duct component 13, or it can be a closed channel that is separately arranged on the shell assembly 11 or the air duct component 13. The present application does not impose any special restrictions on the specific structures of the first air duct 123 and the second air duct 132. In addition, the number of the bending sections of the second air duct 132 can be one, two or more, and the present application does not impose any special restrictions on the specific number of the bending sections of the second air duct 132.

[0048] In some embodiments, as Figures 3 to 5As shown, the heating element 12 may have a first protrusion 125 and a second protrusion 126; the first protrusion 125 may be arranged on the inner wall of the heating element 12, and the second protrusion 126 may be arranged on the bottom of the heating element 12. After the aerosol product 3 is inserted into the heating cavity 124, the first air duct 123 is formed between the inner surface of the heating element 12 and the aerosol product 3.

[0049] In this way, the first raised portion 125 protrudes relative to the inner sidewall of the heating element 12, allowing a gap to be maintained between the aerosol product 3 and the inner sidewall of the heating element 12. The second raised portion 126 protrudes relative to the bottom of the heating element 12, allowing a gap to be maintained between the aerosol product 3 and the bottom of the heating element 12. As a result, airflow can flow along the inner sidewall of the heating element 12 to the bottom of the heating element 12 and ultimately into the aerosol product 3, causing the aerosol product 3 to be atomized to produce an aerosol.

[0050] The first raised portion 125 and the second raised portion 126 may be structures such as convex strips or bumps provided within the heating element 12. The present application does not impose any particular restrictions on the specific shapes of the first raised portion 125 and the second raised portion 126. Furthermore, the heating element 12 may be made of a material with high thermal conductivity, such as aluminum alloy, copper, or aluminum nitride. The present application does not impose any particular restrictions on the specific material of the heating element 12.

[0051] In some embodiments, as Figure 5 As shown, the heating element 12 may include a heating tube 121; the first protrusion 125 may be connected to the second protrusion 126, the first protrusion 125 may be arranged along the axial direction (aa axis direction) of the heating tube 121, and multiple first protrusions 125 may be arranged on the inner side wall of the heating tube 121 along the circumference of the heating tube 121; the second protrusion 126 may be arranged along the radial direction of the heating tube 121, and multiple second protrusions 126 may be arranged at the bottom of the heating tube 121 along the circumference of the heating tube 121.

[0052] Thus, the recessed portion between adjacent first protrusions 125 and the recessed portion between adjacent second protrusions 126 can form a first air channel 123, allowing the air to flow into the bottom of the heating element 12 along the aa axis and into the aerosol product 3. In other embodiments, the first protrusion 125 can also be configured as a spiral protrusion structure along the inner side wall of the heating tube 121, so that the airflow can flow into the bottom of the heating element 12 in a spiral state.

[0053] When the airflow flows into the first air channel 123, the heating element 12 can preheat the airflow in the first air channel 123. The spiral first air channel 123 is also conducive to extending the path of the heating element 12 preheating the airflow, thereby improving the atomization efficiency of the aerosol product 3.

[0054] In some embodiments, as Figure 6 As shown, the heating body 12 may further include a heating element 122 . The heating element 122 may be disposed on the heating tube 121 to heat the heating tube 121 .

[0055] For example, the heating element 122 can be connected to the bottom of the heating tube 121, and the surface of the heating element 122 fits with the bottom of the heating tube 121 to heat the heating tube 121. Among them, the heating element 122 can be set as a serpentine or grid-shaped heating wire or heating strip, and the heating element 122 can be attached to the bottom of the heating tube 121 to save the space volume occupied by the heating element 122, which is conducive to reducing the volume of the atomizer 100. The power supply component 2 can be electrically connected to the heating element 122 to supply power to the heating element 122. In addition, the heating element 122 can be set at the bottom of the heating tube 121 and away from the side of the heating cavity 124, so as to avoid the problem of burning of the aerosol product 3. The present application does not impose any special restrictions on the specific shape of the heating element 122.

[0056] In other embodiments, the heating element 122 may also be attached to the outer wall of the heating tube 121, thereby heating the outer wall of the heating tube 121 and atomizing the aerosol product 3. The heating element 122 disposed on the outer wall of the heating tube 121 may be arranged in sections or regions, so that the heating element 12 can heat different parts of the aerosol product 3 at different temperatures, thereby effectively atomizing the aerosol product 3. This application does not impose any particular restrictions on the specific location of the heating element 122.

[0057] The above embodiment is a detailed introduction to the specific structure of the heating element 12. In order to avoid scalding the user, the following embodiment will introduce the specific structure of the airway component 13 in detail. Figure 3 、 Figure 4 and Figure 7 As shown, the air duct member 13 may have a first notch 1321 and a second notch 1322 connected to the through hole 131, and the outer wall of the air duct member 13 may be provided with a first channel 1323, and the first channel 1323 connects the first notch 1321 and the second notch 1322 to form a second air duct 132; the first notch 1321 can guide the external airflow to bend from the inner wall of the air duct member 13 and flow into the second air duct 132, and the second notch 1322 can guide the external airflow to bend from the outer wall of the air duct member 13 and flow out of the second air duct 132, and the external airflow flows from the second air duct 132 into the first air duct 123.

[0058] When the hot air flows from the first air channel 123 into the second air channel 132 under the action of atmospheric pressure (i.e., when the hot air flows in the opposite direction), the hot air first bends once at the second notch 1322 and flows into the second air channel 132 on the outer wall of the air channel member 13. Then, it bends a second time at the first notch 1321 along the second air channel 132 and flows out of the atomizer 100. Thus, the hot air can bend twice in the second air channel 132, thereby reducing the temperature of the hot air flowing out of the atomizer 100 and preventing the hot air from scalding the user.

[0059] In other embodiments, the second air channel 132 may be configured as a spiral air channel formed on the outer wall of the air channel member 13, so that the hot air flow can meander within the spiral air channel to reduce the temperature of the hot air flowing out of the atomizer 100. Alternatively, a plurality of bumps may be provided on the first channel 1323, so that the second air channel 132 forms a multi-bend air flow channel, thereby increasing the number of meanders of the second air channel 132. The present application does not impose any particular limitation on the specific structure of the second air channel 132.

[0060] In some embodiments, as Figure 7 As shown, the shape of the airway member 13 can be set to a circular ring; a plurality of first notches 1321 can be set on one end surface of the airway member 13, and a plurality of second notches 1322 can be set on the other end surface of the airway member 13, and a first channel 1323 is connected between each first notch 1321 and each second notch 1322. A second channel 133 can be further provided on the outer side wall of the airway member 13 along the circumference of the airway member 13, and the second channel 133 is connected to the plurality of first channels 1323.

[0061] The provision of multiple second air channels 132 along the circumference of the airway member 13 prevents the problem of one second air channel 132 being blocked by liquid impurities, thereby affecting the flow of external air into the atomizer 100. Furthermore, the multiple second air channels 132 allow more external air to flow into the atomizer 100, thereby enabling more complete atomization of the aerosol product 3. The second channel 133 connects the multiple first channels 1323, allowing the multiple second air channels 132 on the airway member 13 to communicate with each other. This not only increases the flow rate of external airflow, but also increases the number of times the hot air flow bends at the airway member 13, thereby reducing the temperature of the hot air flowing out of the atomizer 100.

[0062] In some embodiments, as Figure 7 As shown, the inner side wall of the airway member 13 may be provided with a third protrusion 134 and a fourth protrusion 135; the third protrusion 134 may be provided along the axial direction of the airway member 13 to guide the aerosol product 3 to pass through the through hole 131; the fourth protrusion 135 may be provided along the circumferential direction of the airway member 13 to seal the aerosol product 3 and the airway member 13.

[0063] During the insertion of the aerosol product 3 into the heating chamber 124, the third protrusion 134 arranged axially along the airway member 13 can guide the aerosol product 3 through the through hole 131 and press the aerosol product 3 against the through hole 131 to prevent the aerosol product 3 from escaping from the atomizer 100. For example, the third protrusion 134 can have an inclined surface or an arc surface arranged axially along the airway member 13. The present application does not impose any special restrictions on the specific shape of the third protrusion 134. In addition, the fourth protrusion 135 arranged circumferentially along the airway member 13 can seal with the aerosol product 3 to allow external airflow to flow from the second air channel 132 into the atomizer 100. The material of the airway member 13 can be selected from materials such as silicone or plastic to enhance the sealing performance between the airway member 13, the housing assembly 11, and the aerosol product 3. The present application does not impose any special restrictions on the specific material of the airway member 13.

[0064] In more embodiments, Figure 3 and Figure 4 As shown, the shell assembly 11 may include a top cover 111, a shell body 112 and a bottom shell 113; the shell body 112 can be connected to the bottom shell 113 and together enclose a accommodating cavity 110 with an open end, the heating element 12 is installed in the accommodating cavity 110, the top cover 111 is connected to the open position, and the top cover 111 is provided with a cavity 1110 connected to the heating cavity 124, the airway component 13 is installed in the cavity 1110 and is located at the end of the top cover 111 away from the heating element 12, and the through hole 131 is connected to the cavity 1110.

[0065] Thus, the aerosol product 3 can pass through the through hole 131 and the cavity 1110 and be inserted into the heating cavity 124. The air duct component 13 is installed at the end of the top cover 111 away from the heating element 12, so that the second air duct 132 can be located close to the external air flow, so that when the hot air flow flows back, the hot air flow can be quickly cooled to avoid scalding the user. The heating element 12 is installed in the accommodating cavity 110, and the heating component 122 is arranged at the bottom of the heating tube 121, so that the accommodating cavity 100 has a heat-insulating effect on the heating element 12, thereby avoiding heat loss. Among them, a limiting step can be provided in the top cover 111, and the air duct component 13 can be installed on the limiting step in the cavity 1110.

[0066] In some embodiments, as Figure 3 and Figure 4 As shown, the shell assembly 11 may also include a support member 114; the support member 114 is connected to the inner wall of the shell body 112, one end of the heating element 12 is connected to the support member 114, and the other end of the heating element 12 is suspended in the accommodating cavity 110, and the top cover 111 close to the end of the heating element 12 can press the heating element 12 onto the support member 114.

[0067] The heating element 12 is suspended in the accommodating cavity 110, which can reduce the heat transfer between the heating element 12 and the shell assembly 11, thereby reducing heat loss. The top cover 111 presses the heating element 12 against the support member 114, so that the heating element 12 can be firmly connected to the shell body 112, thereby improving the stability of the heating element 12. In addition, the support member 114 can have an inclined surface inclined toward the heating cavity 124, and a limiting step connected to the inclined surface, so that the heating element 12 can slide into the limiting step through the inclined surface and be fixed to the support member 114 through the limiting step. The present application does not impose any special restrictions on the specific structure of the support member 114.

[0068] In addition, if Figure 3 and Figure 4 As shown, the housing assembly 11 may further include a compression member 115, which may be disposed between the housing 1 and the airway member 13. When the atomizer 100 is installed in the housing 1, the compression member 115 can compress the flexible airway member 13, thereby ensuring a seal between the airway member 13, the aerosol product 3, and the housing 112, thereby allowing external airflow to flow into the atomizer 100 from the second airway 132. The compression member 115 may be an annular pressure plate structure, and the present application does not impose any particular limitation on the specific structure of the compression member 115.

[0069] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
