[0036] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0037] 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).

[0038] In one embodiment, an atomizer device is provided. This atomizer device is a heat-not-burn device, designed to be inserted into an atomizer substrate, such as a cigarette, for heated atomization and inhalation. This atomizer device features a redesigned air inlet channel, with a portion of the air inlet channel positioned on the surface of the atomizer substrate. This allows air entering the atomizer substrate to carry heat energy emitted by the atomizer substrate back into the atomizer substrate, recycling the heat energy and improving heat utilization. Furthermore, positioning the inlet channel entrance on the circumferential side of the nozzle assembly prevents smoke emitted by the atomizer substrate from entering the air inlet channel.

[0039] Please refer to Figures 1 to 3The atomizing device of this embodiment mainly includes a shell 1, a nozzle assembly 2 and a heating element 3. The nozzle assembly 2 and the heating element 3 are arranged in the shell 1, and a portion of the nozzle assembly 2 is exposed from the shell 1.

[0040] The housing 1 comprises an outer shell 11 and an inner shell 12. The inner shell 12 is located within the outer shell 11 and serves as a support structure, securing components within the housing 1. The outer shell 11 can be composed of multiple parts. For example, the bottom of the outer shell 11 may be detachable to facilitate installation and removal of other components within the outer shell 11. The inner shell 12 can be secured to the outer shell 11 by means of snap-fitting, bonding, or other methods. Alternatively, the inner shell 12 and the outer shell 11 may be integrally formed.

[0041] The housing 1 is provided with a mounting groove 13. Specifically, the outer shell 11 is provided with an opening, and the inner shell 12 is provided with a mounting groove 13 aligned with the opening of the outer shell 11. The mounting groove 13 has openings at both ends. The opening at one end of the mounting groove 13 facing the outside of the housing 1 is used to mount the suction nozzle assembly 2, and the opening at the other end of the mounting groove 13 facing the inside of the housing 1 is used to mount the heating element 3. The opening at the bottom of the mounting groove 13 is smaller than the inner diameter of the mounting groove 13, so that the bottom of the mounting groove 13 forms a stepped stop structure. This stepped stop structure can form an axial stop for the suction nozzle assembly 2, preventing the suction nozzle assembly 2 from being squeezed and falling into the housing 1 under the action of external force.

[0042] The nozzle assembly 2 is installed in the mounting groove 13. The nozzle assembly 2 can be fixed in the mounting groove 13 by means of snap connection, bonding, etc., with one end of the nozzle assembly 2 exposed from the mounting groove 13. There is a certain gap between the bottom of the nozzle assembly 2 and the bottom of the mounting groove 13.

[0043] One end of the heater 3 is fixed to the heater mounting base 4, which is mounted in the opening at the bottom of the mounting groove 13. The other end of the heater 3 is located in the mounting groove 13. The portion of the heater 3 located in the mounting groove 13 is used to be inserted into the atomizing substrate 5. The heater 3 can be a cylindrical structure, and the end of the heater 3 located in the mounting groove 13 can be a pointed structure such as a cone to make it easier to insert the heater 3 into the atomizing substrate 5.

[0044] The heating element 3 can be a resistance heating body, the entire heating element 3 is a resistance heating structure, or the circumferential outer surface of the heating element 3 is provided with a resistance heating structure. The heating element 3 can convert electrical energy into thermal energy and transfer the thermal energy to the atomizing matrix to achieve heating and atomization of the atomizing matrix.

[0045] In this embodiment, the nozzle assembly 2 has an atomizing chamber 221, which is used to insert the atomizing matrix 5. When the atomizing matrix 5 is inserted into the atomizing chamber 221, the end of the atomizing matrix 5 contacts the bottom of the atomizing chamber 221. The bottom of the atomizing chamber 221 is provided with a socket for inserting the heating element 3. Part of the heating element 3 extends into the atomizing chamber 221 through the socket at the bottom of the atomizing chamber 221. When the atomizing matrix 5 is inserted into the atomizing chamber 221, the heating element 3 located in the atomizing chamber 221 will be inserted into the atomizing matrix 5, thereby achieving heating of the atomizing matrix 5 from the inside.

[0046] The nozzle assembly 2 is provided with a first air inlet channel a, a second air inlet channel b, and a third air inlet channel c, which are connected in sequence. The first air inlet channel a is located inside the nozzle assembly 2. The first air inlet channel a is located in the portion of the nozzle assembly 2 where the mounting groove 13 is exposed, or the first air inlet channel a is located in the portion of the nozzle assembly 2 near the opening of the mounting groove 13. One end of the first air inlet channel a is located on the circumferential outer side of the nozzle assembly 2 and is connected to the atmosphere. The other end of the first air inlet channel a is located on the circumferential inner side of the atomizing chamber 221 of the nozzle assembly 2. The first air inlet channel a is used to introduce the atmosphere into the nozzle assembly 2. The second air inlet channel b is the gap space between the circumferential inner side of the atomizing chamber 221 and the atomizing matrix 5, that is, the second air inlet channel b is enclosed by the circumferential inner side of the atomizing chamber 221 and the atomizing matrix 5, and the second air inlet channel b extends along the axial direction of the atomizing chamber 221, and one end of the second air inlet channel b is connected with the other end of the first air inlet channel a, and the other end of the second air inlet channel b extends out of the bottom edge of the atomizing chamber 221, that is, the other end of the second air inlet channel b passes through the mouthpiece assembly 2. The third air inlet channel c is located on the outside of the mouthpiece assembly 2, and one end of the third air inlet channel c is connected with the other end of the second air inlet channel b, and the other end of the third air inlet channel c extends to the inner side of the bottom middle part of the atomizing chamber 221, that is, the other end of the third air inlet channel c extends into the atomizing chamber 221, so as to introduce air into the end of the atomizing matrix 5.

[0047] In this embodiment, since the second air inlet channel b in the air inlet channel of the suction nozzle assembly 2 is arranged between the atomizing chamber 221 and the atomizing matrix 5, when the external air enters the bottom of the atomizing matrix 5, it will pass through the circumferential outer side of the atomizing matrix 5, and can bring the heat energy circumferentially emitted during the heating process of the atomizing matrix 5 back into the atomizing matrix 5, thereby improving the heat utilization rate of the heated atomizing matrix 5 and reducing the heat energy diffusion loss of the heated atomizing matrix 5.

[0048] Moreover, in this embodiment, the third air inlet channel c is located on the inner side of the bottom of the atomizing chamber 221, so that the atmosphere can be more evenly introduced into the middle position of the end of the atomizing matrix 5, thereby preventing the atmosphere from directly entering the atmosphere from the end edge of the atomizing matrix 5 and lacking air in the middle position.

[0049] In one embodiment, the third air inlet channel c may also be located inside the bottom of the atomizing chamber 221. For example, the bottom of the atomizing chamber 221 may be provided with a raised or recessed structure, and a gap space may be formed between the end surface of the atomizing matrix 5 and the bottom of the atomizing chamber 221. This gap space forms the third air inlet channel c. This arrangement allows the outside air to be introduced into the end of the atomizing matrix 5 and then into the atomizing matrix 5.

[0050] In one embodiment, the nozzle assembly 2 is provided with a plurality of first air inlet channels a and a plurality of second air inlet channels b, and the plurality of first air inlet channels a are distributed in the same radial cross-section of the nozzle assembly 2 and are evenly distributed. Each first air inlet channel a is connected to a corresponding second air inlet channel b. The third air inlet channel c can be a larger gap space area, and a third air inlet channel c is connected to the plurality of second air inlet channels b. Such an arrangement can improve air intake efficiency, and the evenly distributed first air inlet channels a can also allow the atmosphere to enter the different end surface positions of the atomized substrate 5 more evenly, thereby improving the uniformity of baking.

[0051] In other embodiments, the nozzle assembly 2 is provided with a first air inlet channel a and a second air inlet channel b, which can also enable the external atmosphere to be introduced into the atomizing matrix 5 .

[0052] Please refer to Figure 3 、 Figure 4 and Figure 5 In one embodiment, the nozzle assembly 2 includes an outer shell 21 and an inner pocket 22. The outer shell 21 is connected to the housing 1 and is located in the mounting groove 13. The outer shell 21 can be fixedly connected to the inner shell 12 by means of snap connection, welding, etc. The inner pocket 22 is located within the outer shell 21 and has an atomization chamber 221.

[0053] The first air inlet passage a radially penetrates the outer shell 21 and the inner pocket 22 , and the second air inlet passage b is located in the inner pocket 22 and extends to the bottom edge of the inner pocket.

[0054] An axial groove is provided on the circumferential inner side of the inner pocket 22. One end of the groove is sealed, and the other end extends to the bottom edge of the inner pocket 22. The inner diameter of the inner pocket 22 is equal to or slightly smaller than the outer diameter of the atomizing matrix 5. When the atomizing matrix 5 is inserted into the atomizing chamber 221, the circumferential outer side of the atomizing matrix 5 abuts the circumferential inner side of the inner pocket 22 and covers the radial opening of the groove. In other words, the groove and the atomizing matrix 5 enclose a second air inlet channel b.

[0055] The outer sleeve 21 has an opening at the bottom of the mounting slot 13. A gap exists between the bottom outer side of the inner pocket 22 and the bottom of the mounting slot 13, forming a third air inlet channel c. The bottom of the inner pocket 22 is provided with an air outlet 222 and an air inlet 223. The air outlet 222 is located at the bottom edge of the inner pocket 22, while the air inlet 223 is located in the middle of the bottom of the inner pocket 22. The inner pocket 22 also has an insertion hole 224 in the middle of the bottom, which allows the heater 3 to be inserted into the atomizing chamber 221. One end of the second air inlet channel b is connected to the air outlet 222, and the third air inlet channel c is connected to both the air outlet 222 and the air inlet 223. The third air inlet channel c is connected to the second air inlet channel b through the air outlet 222, and to the bottom inner side of the atomizing chamber 221 through the air inlet 223.

[0056] The inner diameter of the insertion hole 224 may be larger than the outer diameter of the heating element 3 , and there is a gap between the insertion hole 224 and the heating element 3 , so that the insertion hole 224 also serves as an air intake.

[0057] The outer cover 21 and the inner pocket 22 are nested inside and outside, and the inner pocket 22 can be set as a heat-conducting metal component, so that the inner pocket 22 can also heat the circumferential side of the atomized substrate 5. The outer cover 21 can be set as a heat-resistant plastic component to prevent internal heat from escaping and losing, and to prevent the exposed part from scalding the user.

[0058] Please refer to Figure 5 In one embodiment, the inner diameter of the outer shell 21 is larger than the outer diameter of the inner pocket 22. The outer shell 21 and the inner pocket 22 define an annular cavity with sealed ends. This annular cavity can provide air insulation and reduce the rate of heat leakage from the inner pocket 22. The first air inlet passage a can radially penetrate and connect to the annular cavity.

[0059] The first end of the outer sleeve 21 exposed from the mounting groove 13 is provided with an abutment portion 211 extending radially inward. The abutment portion 211 is an annular boss structure. One end of the inner pocket 22 is connected to the abutment portion 211 of the outer sleeve 21. The abutment portion 211 realizes the sealing of one end of the annular cavity between the outer sleeve 21 and the inner pocket 22.

[0060] A first engaging portion 212 is provided at one end or the middle portion of the outer cover 21, away from the abutment portion 211. A second engaging portion 225 is provided at a corresponding position on the circumferential outer side of the inner pocket 22. The first engaging portion 212 and the second engaging portion 225 engage to secure the inner pocket 22 within the outer cover 21 and simultaneously seal the other end of the annular cavity between the outer cover 21 and the inner pocket 22. One of the first engaging portion 212 and the second engaging portion 225 can be an annular groove, while the other can be an annular protrusion or an annular spring, either of which can achieve both engagement and sealing.

[0061] In other embodiments, the two ends of the inner pocket 22 can also be fixedly connected to the outer shell 21 through a protruding structure and bonding, and the two ends of the annular cavity between the outer shell 21 and the inner pocket 22 can be sealed.

[0062] Please refer to Figure 3 In one embodiment, a sunken step 131 is provided at the opening of the mounting groove 13, and the inner shell 12 forms the sunken step 131. The outer shell 21 is provided with an annular protrusion 213 that cooperates with the sunken step 131. The annular protrusion 213 is installed on the sunken step 131 to form an axial limit for the outer shell 21.

[0063] The outer diameter of the annular protrusion 213 is smaller than the inner diameter of the sunken step 131, and a transition air intake channel d is formed between the annular protrusion 213 and the sunken step 131. The first air intake channel a penetrates the annular protrusion 213 radially, and the transition air intake channel d is connected to the first air intake channel a. The transition air intake channel d is used to introduce the atmosphere into the first air intake channel a.

[0064] With such an arrangement, the opening of the first air intake passage a can be hidden, forming a labyrinth structure, thereby preventing foreign objects from entering the air intake passage and ensuring smooth flow of the air intake passage.

[0065] In other embodiments, the opening of the first air inlet channel a may also be directly connected to the atmosphere to introduce the atmosphere into the atomized substrate 5 .

[0066] Please refer to Figure 6 In one embodiment, an electronic atomization device is provided. The electronic atomization device includes a control board 6, a battery 7 and an atomization device in any of the above embodiments.

[0067] In this embodiment, the control board 6 and the battery 7 are installed in the shell 1, and the control board 6 is electrically connected to the battery 7 and the heating element 3. The control board 6 is used to control the heating element 3 to heat the atomizing matrix 5, and the battery 7 is used to provide stored electrical energy and provide electrical energy to the heating element 3.

[0068] The housing 1 may also be provided with a charging port and the like, and the charging port is used to charge the battery 7 to increase the service life of the electronic atomization device.

[0069] In this embodiment, since the second air inlet channel b in the air inlet channel of the suction nozzle assembly 2 is arranged between the atomizing chamber 221 and the atomizing matrix 5, when the external air enters the bottom of the atomizing matrix 5, it will pass through the circumferential outer side of the atomizing matrix 5, and can bring the heat energy circumferentially emitted during the heating process of the atomizing matrix 5 back into the atomizing matrix 5, thereby improving the heat utilization rate of the heated atomizing matrix 5 and reducing the heat energy diffusion loss of the heated atomizing matrix 5.

[0070] 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.
