[0060] "Atomizing matrix" refers to a mixture or auxiliary substance that can be wholly or partially atomized into an aerosol by an electronic device or similar device. Atomizing matrix can be liquid media such as e-cigarette liquids, medical drugs, and skin lotions. By atomizing these media, an aerosol that can be inhaled or absorbed can be delivered to the user.

[0061] "Aerosol" refers to a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gaseous medium.

[0062] A "nebulizer" is a device that uses heat or ultrasound to form an aerosol from a stored atomizable substrate. The atomizing core is one of the main components of an atomizer.

[0063] In electronic cigarette technology, the atomizer core includes a heating element and an wicking component. The heating element heats the e-liquid to form vapor, while the wicking component guides the atomizing matrix to the heating element. The heating element can be made of conductive metal or graphene, carbon nanomaterials, while the wicking component can be made of ceramic, glass, quartz, mica, cotton, or fiber materials.

[0064] The following description, in conjunction with the accompanying drawings, further illustrates this application:

[0065] See Figure 1-13 This embodiment provides an electronic atomization system, including an atomizing device 1 and / or a power supply component 2.

[0066] In some embodiments, the atomizing device 1 includes a cartridge shell 10, a storage chamber 301, a heating chamber 302, and a heating element 321.

[0067] Reference Figure 2-5 In some embodiments, the storage chamber 301 is used to store the atomizing matrix, and the heating chamber 302 is used to heat the atomizing matrix. The heating chamber 302 is located outside the storage chamber 301. Specifically, for example... Figure 3As shown, the heating chamber 302 is located on one side of the storage chamber 301. The storage chamber 301 and the heating chamber 302 are connected by a connecting hole 303. The transverse arrangement of the storage chamber 301 and the heating chamber 302 prevents the backflow of un-atomized residual atomized matrix in the heating chamber 302, which would contaminate the unused atomized matrix in the storage chamber 301 and affect the user's vaping experience. The storage chamber 301 is equipped with a movable piston 311 for pushing the atomized matrix through the connecting hole 303 into the heating chamber 302. The connecting hole 303 is located at one end of the side wall 42 of the storage chamber 301 and the heating chamber 302, and the piston 311 is located at the other end of the storage chamber 301. In use, the storage chamber 301 stores atomizing substrates such as e-liquid or e-cream. The atomizing substrate in the storage chamber 301 enters the heating chamber 302 through the connecting hole 303 to provide atomizing substrates for the heating chamber 302. When the atomizing substrate in the storage chamber 301 decreases, the piston 311 moves upward, pushing the atomizing substrate in the storage chamber 301 into the heating chamber 302 through the connecting hole 303, so as to make full use of the atomizing substrate and avoid waste.

[0068] In some embodiments, refer to Figure 2 and Figure 5 The piston 311 includes a body 3110, at least a portion of which is covered with a sealing compound 3111. The sealing compound 3111 is made of plastic, rubber, or silicone material, which increases the sealing performance of the piston 311 and prevents oil leakage when the piston 311 moves up and down. The sealing compound 3111 may cover the side of the body 3110 facing the storage chamber 301, or it may cover the other side, or the sealing compound 3111 may cover the entire piston 311.

[0069] In some embodiments, the heating chamber 302 is equipped with a heating element 321, and the atomizing device 1 includes a cup body 40, within which the heating chamber 302 is formed. (Refer to...) Figure 10 , 11 The cup body 40 includes a bottom wall 41 and a side wall 42. At least the bottom wall 41 of the cup body 40 is an oil guiding component for guiding oil. The heating element 321 is disposed on the outside of the bottom wall 41 of the cup body 40. The oil guiding component is made of glass, ceramic, mica or quartz with a multi-microporous structure. The heating element 321 is made of conductive metals such as copper or nickel-chromium alloy or is made of graphene or carbon nanomaterials, and is attached to the surface of the oil guiding component by printing, etching or bonding, embedding or other methods. In use, the atomizing matrix stored in the heating chamber 302 is transferred to the heating element 321 through the microporous structure of the oil guiding component and is heated and atomized by the heating element 321.

[0070] In some embodiments, refer to Figure 11The heating element 321 is annular and includes a heating part 310 and a thin oil-blocking part 312 for preventing the atomizing matrix from continuing to be transmitted. Specifically, the heating part 310 includes a first heating part 3101 and a second heating part 3102, and the oil-blocking part 312 includes a first oil-blocking part 3121 and a first oil-blocking part 3122. The first oil-blocking part 3121, the first heating part 3101, the first oil-blocking part 3122, and the second heating part 3102 are connected end to end to form a closed annular thin-sheet structure, as shown in the figure. Figure 5 The cup body 40 is covered with a sealing element 43 made of rubber or silicone. The sealing element 43 has openings corresponding to the heating element 310 to facilitate the discharge of atomized gas. An oil-blocking element 312 further prevents oil leakage. The heating element 310 includes a zigzag structure with reciprocating bends, allowing for a more compact arrangement within a limited area and increasing the heat dissipation area. Simultaneously, the zigzag structure also improves the mechanical strength of the heating element 310 to some extent. The oil-blocking element 312 can be a thin sheet structure with minimal thickness. Both the heating element 310 and the oil-blocking element 312 are made of conductive metal. The area of ​​the oil-blocking element 312 is larger than the area of ​​the heating element 310.

[0071] In some embodiments, refer to Figure 4 and Figure 11 The atomizing device 1 further includes a first contact electrode 71 and a second contact electrode 72, which are used for electrical connection with the power supply component 2. This contact-type electrical connection method is more convenient and faster. The first contact electrode 71 and the second contact electrode 72 are respectively electrically connected to the heating element 321 through conductive elements. Specifically, the first oil-blocking part 3121 and the first oil-blocking part 3122 of the heating element 321 are respectively electrically connected to the first contact electrode 71 and the second contact electrode 72 through wires. The first contact electrode 71, the second contact electrode 72, and the conductive elements are all made of conductive metal.

[0072] In some embodiments, refer to Figure 12The atomizing device 1 further includes an atomizing chamber 50, which is formed circumferentially and corresponds to the heating element 321. That is, the atomizing chamber 50 is longitudinally located below the corresponding heating element 321. The atomizing chamber 50 has an air inlet 51 and an air outlet 52, which are symmetrical and correspond to the positions of the first oil-blocking parts 3121 and 3122, respectively. This allows the airflow to completely pass through the first heating part 3101 and the second heating part 3102, carrying away the aerosol generated by heating and atomization. Specifically, the atomizing chamber 50 is an annular space located at the bottom of the heating element 321. The air inlet 51 and the air outlet 52 are symmetrically arranged on both sides of this annular space. The ring structure of the atomizing chamber 50 makes the atomization air path longer, and together with the heating element 321 at the top, makes atomization more complete.

[0073] In some embodiments, refer to Figure 5 The atomizing device 1 includes an oil receiving groove 60, which is located below the side of the cup body 40 with the heating element 321. The annular heating element 321 surrounds a central area, and the oil receiving groove 60 corresponds to this central area, meaning it is located below the central area. The atomizing chamber 50 surrounds the outer periphery of the oil receiving groove 60. The oil receiving groove 60 is used to collect any un-atomized atomized matrix that leaks out from the top of the cup body 40, preventing contamination of the electronic components inside the atomizing device 1.

[0074] In some embodiments, the atomizing device 1 further includes sealing silicone 20 and a chamber 30, such as Figure 5 and Figure 12 As shown, the chamber 30 includes a horizontally arranged air guiding zone 30a, an atomizing zone 30b, and an oil storage zone 30c. The oil storage zone 30c is a tubular structure with open ends. One end of the tubular structure is sealed by a piston 311, and the other end of the tubular structure is sealed by a sealing silicone 20. The space enclosed by the tubular structure, the sealing silicone 20, and the piston 311 serves as a storage chamber 301. The atomizing matrix in the storage chamber 301 is transferred to the atomizing zone 30b and heated and atomized by the heating element 321 of the atomizing zone 30b. The smoke formed by atomization is discharged through the air guiding zone 30a.

[0075] In some embodiments, refer to Figure 3 , 513. The atomizing device 1 further includes a mouthpiece 11 and a smoking port 12, which are integrally formed on the cartridge shell 10. In some other embodiments, the mouthpiece 11 and the smoking port 12 may be separately provided or not provided on the cartridge shell 10, which is not limited here. The mouthpiece 11 is provided with a smoking port 111, which is connected to a smoke exhaust channel 121. The atomizing device 1 also includes an air intake channel 330, and the air intake channel 330, air intake section 51, atomizing chamber 50, air outlet section 52, smoke exhaust channel 121, and smoking port 111 are sequentially connected.

[0076] In some embodiments, the storage chamber 301 is equipped with an oil injection hole 80. During production, the storage chamber 301 can be filled with oil before the sealing silicone 20 is installed, or the sealing silicone 20 can be installed first and then oil can be injected into the storage chamber 301 through the oil injection hole 80.

[0077] In some embodiments, the housing 30 is made of a transparent or translucent material, and the cartridge shell 10 corresponding to the storage chamber 301 is provided with an observation window 13 (e.g., Figure 1 As shown in the figure, this facilitates observation of the remaining amount of atomized matrix in the storage chamber 301.

[0078] In some embodiments, the power supply assembly 2 is used to assemble with the atomizing device 1. The power supply assembly 2 includes a vapor chamber 201, a battery cell 202, and a pusher 3 for moving the piston 311. One end of the pusher 3 is opposite to the piston 311. The battery cell 202 is electrically connected to a heating element 321 for supplying power to it. The power supply assembly 2 also includes a drive member 4 for driving the pusher 3. Figure 3 As shown, the pusher 3 abuts against the piston 311, and the drive 4 drives the pusher 3 to slide upward, thereby driving the piston 311 to move upward in the storage chamber 301, squeezing the atomized matrix into the heating chamber 302. In this application, the pusher 3 abuts against the piston 311, so that the movement of the pusher will not be affected when the power supply assembly and the atomizing device are disassembled and installed, which facilitates the replacement of the atomizing device. In some other embodiments, the piston 311 can also be fixed on the pusher 3 so that it can move up and down with the pusher 3.

[0079] In some embodiments, one end of the driving member 4 is connected to a knob 5, and the driving member 4 is a rotatable component that rotates as the knob 5 rotates.

[0080] In some embodiments, the pusher 3 is a hollow cylinder with internal threads, and the drive 4 is rod-shaped, disposed inside the hollow cylinder of the pusher 3 with external threads on its outer periphery. The drive 4 is threadedly connected to the pusher 3. The power assembly 2 further includes a fixing bracket 6 for limiting the drive 4, so that the drive 4 can only rotate and cannot move up and down. The fixing bracket 6 can be a component separately disposed inside the cigarette holder 201, or it can be the cigarette holder 201 itself. The function of the fixing bracket 6 is to limit the movement of the drive 4, so that it can only rotate and cannot move up, down, left, or right. The drive 4 is rotatably connected to the fixing bracket 6, and the pusher 3 moves as the drive 4 rotates. Specifically, for example... Figure 3 As shown, as the drive member 4 rotates, the pusher 3 moves upward, thereby squeezing the piston 311 into the storage chamber 301.

[0081] In some embodiments, the fixed frame 6 is provided with a guide assembly 7 for guiding the movement direction of the push member 3. The guide assembly 7 includes a guide groove 710 and a guide block 720 slidably connected in the guide groove 710. The guide groove 710 is arranged along the axial direction of the push member 3. One of the guide groove 710 and the guide block 720 is provided on the fixed frame 6, and the other of the guide groove 710 and the guide block 720 is provided on the outer wall of the push member 3. The guide assembly 7 is provided to improve the stability of the push member 3 moving up and down.

[0082] In some embodiments, the power supply assembly 2 further includes at least one positioning protrusion 810 and at least one positioning groove 820 for receiving the positioning protrusion 810. The power supply assembly 2 also includes a positioning component 8, which is disposed adjacent to the knob 5. One of the positioning groove 820 and the positioning protrusion 810 is disposed on the knob 5, and the other of the positioning groove 820 and the positioning protrusion 810 is disposed on the positioning component 8. The knob 5 is positioned at a preset position by rotation relative to the positioning component 8 via the positioning groove 820 and the positioning protrusion 810. The positioning component 8 may be a frame separately disposed within the cigarette holder 201, or it may be the cigarette holder 201 itself. (Refer to...) Figure 9 The positioning component 8 is used to position the knob 5. By setting the positioning groove 820 and the positioning protrusion 810, the positioning protrusion 810 moves from one positioning groove 820 to another positioning groove 820 each time the knob 5 rotates, thereby fixing the angle of the knob 5 each time and fixing the distance that the pusher 3 and piston 311 move accordingly, so as to realize the function of quantitative oil squeezing.

[0083] In some embodiments, the positioning groove 820 and the positioning protrusion 810 are adapted to each other, and the number of one of the positioning groove 820 and the positioning protrusion 810 is one, while the number of the other of the positioning groove 820 and the positioning protrusion 810 is multiple.

[0084] In some embodiments, the power supply assembly 2 is detachably connected to the atomizing device 1. Specifically, the atomizing device 1 and the power supply assembly 2 are connected by snap-fit ​​or magnetic attraction. The power supply assembly 2 further includes a third contact electrode 73 for conductive contact with the first contact electrode 71 of the atomizing device 1 and a fourth contact electrode 74 for conductive contact with the second contact electrode 72 of the atomizing device 1.
