[0030] Embodiment 1

[0031] This embodiment is suitable for a paste-like aerosol matrix. Since the paste-like aerosol matrix has a high viscosity, it is not easy to leak oil before atomization, and has a good user experience. In addition, the aerosol matrix has a variety of specifications with different components, and users can choose according to their needs.

[0032] See also Figures 1 to 3 This embodiment provides a nebulizer 10 . Specifically, the nebulizer 10 includes a shell 100 , an aerosol generating element 200 and a cover 300 .

[0033] The housing 100 is made of plastic material and has excellent insulation. In addition, in the preparation process, the housing 100 made of plastic material is directly formed by injection molding, which has a simple process and a low preparation cost.

[0034] In this embodiment, the shell 100 is provided with a accommodating cavity (not shown in the figure) and an airflow channel 110. The airflow channel 110 extends along a first direction. In this embodiment, the first direction can be set as the axial direction of the shell 100. The accommodating cavity opens on the surface of the shell 100. The airflow channel 110 is located in the shell 100, and the airflow channel 110 is spaced apart from the accommodating cavity.

[0035] The aerosol generating element 200 is installed in the accommodating cavity, and the aerosol generating element 200 includes an integrally formed heating portion 210 and a storage portion 220. The heating portion 210 is located on one side of the storage portion 220 along the second direction, and the second direction is perpendicular to the first direction. Since the first direction is configured as the axial direction of the shell 100, the second direction is the radial direction of the shell 100. During inhalation, the shell 100 is placed vertically, and the heating portion 210 is located on the left side of the storage portion 220. When the aerosol matrix is ​​continuously consumed, the contact area between the aerosol matrix and the heating portion 210 gradually decreases, which can effectively reduce the risk of burning of the aerosol matrix due to excessive temperature. In addition, such a design is also conducive to sucking out the atomized aerosol and reducing the residual amount of aerosol in the airflow channel 110. In this embodiment, the accommodating cavity and the airflow channel 110 are isolated by the heating portion 210.

[0036] This embodiment simplifies the structure of the atomizer 10 by providing an integrally formed heating portion 210 and storage portion 220, making it easier to assemble. In addition, the integrally formed heating portion 210 and storage portion 220 do not have any installation gaps, thereby reducing the risk of oil leakage and preventing burning.

[0037] Please refer to Figure 3 and Figure 4 The storage portion 220 includes a first end 221 and a second end 222, the first end 221 is provided with a first opening, and the second end 222 is provided with a second opening. In this embodiment, it can be set that the storage portion 220 is cup-shaped, and the inner wall of the storage cavity 223 is tapered along the first direction, and the diameter of the first opening is greater than the diameter of the second opening.

[0038] In addition, the storage portion 220 is provided with a storage cavity 223, which is located between the first opening and the second opening. The first opening is connected to the opening of the accommodating cavity, that is, the storage cavity 223 is in an open state, and the user can insert the aerosol matrix from the top of the storage cavity 223, which is simple and quick.

[0039] In this embodiment, the storage portion 220 may be made of a dense ceramic material, a plastic material, or a glass material.

[0040] The heating part 210 includes an integrally formed heating element 211 and a heat conductor 212, that is, the heating element 211, the heat conductor 212 and the storage part 220 are integrally formed, which is simpler in process manufacturing and does not require additional assembly. The heating element 211 can heat the heat conductor 212, thereby improving the uniformity and stability of aerosol matrix atomization.

[0041] The heat conductor 212 and the storage portion 220 are integrally formed, and the heat conductor 212 is provided with the above-mentioned inner cavity 2121. In the present embodiment, the heat conductor 212 is the main body of the heating portion 210, and has the function of fixing the heating element 211. The heat conductor 212 is made of a microporous ceramic material, which is not only convenient for the penetration of the aerosol matrix, but also has good thermal conductivity, and can evenly absorb the heat of the heating element 211 to various positions of the heat conductor 212, thereby ensuring that the temperature of various positions of the heat conductor 212 rises evenly, thereby avoiding the burning of the aerosol matrix.

[0042] In this embodiment, the heating portion 210 and the second end 222 are integrally formed to block the second opening. Specifically, the periphery of the heating portion 210 abuts against the inner wall of the second opening to form a seal.

[0043] The heat conductor 212 is also provided with an inner cavity 2121, which is connected to the storage cavity 223, and the diameter of the inner cavity 2121 is smaller than the diameter of the second opening. Therefore, this embodiment maximizes the contact area between the heating portion 210 and the aerosol matrix, ensuring that the heating portion 210 can heat and atomize the aerosol matrix located in the inner cavity 2121 to the greatest extent, making local heating less likely to occur, thereby reducing the occurrence of burning.

[0044] The heating element 211 is located on the side of the heat conductor 212 away from the storage portion 220. It is understandable that the heating element 211 needs to be powered to achieve the heating function. Since the housing 100 of this embodiment is made of plastic material, it has good insulation performance, which ensures the safety of electricity use for users.

[0045] See also Figure 5 The heating element 211 includes a first electrode sheet 2111, a second electrode sheet 2112 and a heating wire 2113, and the heating wire 2113 is respectively connected to the first electrode sheet 2111 and the second electrode sheet 2112. In order to improve the uniformity of heating, in this embodiment, the heating wire 2113 is arranged in a polygonal array, and the heating wire 2113 is located in the middle of the heat conductor 212, and the two ends of the heating wire 2113 are arranged in a shape that is convenient for contacting the first electrode sheet 2111 and the second electrode sheet 2112, and the first electrode sheet 2111 and the second electrode sheet 2112 are respectively located on both sides of the heating wire 2113.

[0046] Please continue reading Figure 3 The cover 300 is sealed and covers the storage cavity 223, and the cover 300 is fixedly connected to the housing 100. Specifically, after the aerosol matrix is ​​placed, the cover 300 covers the first opening, thereby changing the storage cavity 223 from an open state to a closed state, effectively preventing the aerosol matrix from contacting the external environment.

[0047] In order to achieve a sealed connection between the cover body 300 and the storage cavity 223, the present embodiment further includes a sealing member 400, which is installed between the storage portion 220 and the cover body 300. In the present embodiment, the sealing member 400 can be set to be an O-ring.

[0048] In addition, in this embodiment, the cover 300 and the housing 100 are connected by snap fastening, thereby achieving a fixed connection between the cover 300 and the housing 100. This embodiment utilizes the cooperation between the housing 100 and the cover 300 to better install the aerosol generating element 200, thereby improving the integrity of the atomizer 10.

[0049] It is understandable that the snap connection can be a detachable connection or a non-detachable connection. The following describes two different connection methods in detail.

[0050] When a detachable connection is adopted, the cover body 300 can be repeatedly disassembled and assembled to add aerosol matrix, thereby achieving the purpose of reuse and saving user usage costs.

[0051] When a non-detachable connection is adopted, before the aerosol matrix is ​​placed, the shell 100 and the cover 300 are split. When the user selects an aerosol matrix and places it into the storage cavity 223, the cover 300 is closed with the shell 100. When the aerosol matrix is ​​used up, the atomizer 10 cannot be reused, thereby protecting the user's inhalation hygiene. In addition, the atomizer 10 is a disposable product with good anti-counterfeiting performance.

[0052] This embodiment can meet the personalized needs of users. After the user selects the specifications of the aerosol matrix, the user can add it by himself, which makes this embodiment more flexible and provides users with a good usage experience.

[0053] Furthermore, in this embodiment, the cover 300 is made of glass material with good transparency, which is convenient for the user to observe the usage of the aerosol matrix and the remaining amount of the aerosol matrix at any time. Especially during inhalation, the user can adjust the clamping angle in time according to naked eye observation.

[0054] See also Figures 1 to 3 Based on the above content, the installation principle of the disposable atomizer 10 is further described in this embodiment as follows:

[0055] S100. The sealing member 400 is mounted on the storage portion 220;

[0056] S200. The integrally formed storage portion 220 and heating portion 210 are placed into the accommodating cavity from the upper opening, and the sealing member 400 is ensured to be located at one end of the storage portion 220 close to the opening.

[0057] S300. Inserting an aerosol matrix from the first opening above;

[0058] S400. Fix the cover 300 and the housing 100 together.

[0059] This embodiment simplifies the preparation and installation steps by integrally forming the heating element 211, the heat conductor 212 and the storage portion 220, solves the problem of oil leakage from gaps caused by installation, and avoids the problem of burning caused by local temperature rise, and has a good prospect for use.

[0060] Embodiment 2

In this embodiment, the aerosol matrix is ​​installed in the storage part 220 of the nebulizer 10, and the storage part 220 is provided with a storage cavity 223.

[0062] The aerosol generating device also includes a battery, which is electrically connected to the heating element 211 of the atomizer 10. When the aerosol generating device is started, the battery supplies power to the heating element 211, the heating element 211 generates heat, and the heat conductor 212 absorbs the heat of the heating element 211 and its temperature rises, thereby atomizing the aerosol matrix in the storage cavity 223 to form an aerosol, and the atomized aerosol is in the form of smoke.

[0063] Specifically, the aerosol generating device further includes a suction nozzle 20 , and the air flow channel 110 is connected to the suction nozzle 20 . When the user performs a suction action, the suction force draws the air flow channel 110 to the suction nozzle 20 .

[0064] The use principle of the aerosol generating device is further described in this embodiment as follows: when the aerosol generating device is started and powered on, the heating portion 210 of the atomizer 10 atomizes the aerosol matrix stored in the storage portion 220 to generate an aerosol. At this time, the user performs an inhalation action through the mouthpiece 20.
