[0056] FIG1 is a schematic diagram of an electronic atomization device provided in an embodiment of the present application.

[0057] As shown in FIG1 , the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20. In some examples, the atomizer 10 and the power supply assembly 20 are not detachable. In some examples, the atomizer 10 and the power supply assembly 20 are detachably connected, such as by an interference fit, a snap connection, or a magnetic connection.

[0058] The nebulizer 10 is used to heat and nebulize a liquid matrix to generate an aerosol.

[0059] The power supply assembly 20 includes a battery cell 21 and a circuit 22 .

[0060] The battery cell 21 provides power for operating the electronic atomization device 100. The battery cell 21 can be a rechargeable battery cell or a disposable battery cell.

[0061] The circuit 22 can control the overall operation of the electronic atomization device 100. The circuit 22 controls not only the operation of the battery cell 21 and the atomizer 10, but also the operation of other components in the electronic atomization device 100.

[0062] FIG2 to FIG13 are schematic structural diagrams of an atomizer according to an embodiment; the atomizer 10 of this embodiment includes:

[0063] The housing 101 has a mouthpiece 101a at its proximal end and an opening 101b at its distal end. The mouthpiece 101a can serve as an aerosol outlet, and a user or inhaler can inhale the aerosol generated by the electronic atomization device 100 through the mouthpiece 101a. An aerosol transmission tube 101c and a liquid storage chamber 101d are provided within the housing 101. The upper end of the aerosol transmission tube 101c is connected to the mouthpiece 101a. The liquid storage chamber 101d is used to store a liquid matrix. The liquid storage chamber 101d is connected to the opening 101b, and the atomization assembly 102 and the sealing member 103 can be assembled into the housing 101 through the opening 101b.

[0064] In further implementation, the inner surface of the housing 101 further has a positioning column 101e, and when the sealing member 103 is assembled into the housing 101 through the opening 101b, the upper end 103a of the sealing member 103 can be positioned by the positioning column 101e.

[0065] The atomizing assembly 102 includes a liquid guiding element 102a, a heating element 102b, and a bracket 102c.

[0066] The liquid-conducting element 102a is used to draw liquid matrix from the liquid storage chamber 101d and transfer the liquid matrix to the heating element 102b. The liquid-conducting element 102a is block-shaped. The size of the liquid-conducting element 102a along the width direction of the atomizer 10 (shown in the Y direction in Figure 2) is larger than the size of the liquid-conducting element 102a along the length direction (shown in the X direction in Figure 2) or the thickness direction (shown in the Z direction in Figure 2) of the atomizer 10, and the size of the liquid-conducting element 102a along the thickness direction of the atomizer 10 is larger than the size of the liquid-conducting element 102a along the length direction of the atomizer 10. In one example, the liquid-conducting element 102a is flexible. For example, the liquid-conducting element 102a includes porous capillary fiber elements such as flexible cotton fibers, non-woven fibers, sponges, etc. In another example, the liquid-conducting element 102a is a rigid porous body, such as a porous ceramic body, porous glass or foam metal.

[0067] The bracket 102c is generally block-shaped. The top surface of the bracket 102c faces the liquid storage chamber 101d, and the bottom surface of the bracket 102c faces the bottom cover 104. The bracket 102c defines a first receiving chamber 102c1. The top surface of the bracket 102c has an opening that communicates with the first receiving chamber 102c1. The first receiving chamber 102c1 is used to receive or accommodate the liquid-conducting element 102a. The first receiving chamber 102c1 can receive the liquid matrix absorbed by the liquid-conducting element 102a, thereby facilitating the liquid-conducting element 102a to retain the liquid matrix and reducing the chance of the liquid matrix leaking to the bottom cover 104. The shape of the first receiving chamber 102c1 matches the shape of the liquid-conducting element 102a. The dimension of the liquid-guiding element 102a along the length direction of the atomizer 10 is slightly larger than the dimension of the first accommodating cavity 102c1 along the length direction of the atomizer 10, for example, slightly larger by 0.5 to 1 mm. In this way, part of the liquid-guiding element 102a protrudes from the opening on the top surface of the bracket 102c, which is conducive to the liquid-guiding element 102a maintaining contact with the heating part of the heating element 102b, thereby forming a good liquid-guiding relationship.

[0068] The heating element 102b is used to heat the atomized liquid substrate to generate an aerosol.

[0069] The heating element 102b includes a first electrode, a second electrode, and a heating portion connected to the first and second electrodes. The first and second electrodes are spaced apart along the width of the atomizer 10 to increase the area of ​​the heating portion, which extends between the first and second electrodes. During use, the first and second electrodes define the electrical connection area of ​​the heating element 102b, while the heating portion defines the heating area of ​​the heating element 102b.

[0070] The dimensions of the first electrode and the second electrode along the thickness direction of the atomizer 10 are consistent with the dimensions of the bracket 102c along the thickness direction of the atomizer 10, thereby improving the sealing reliability of the atomizer assembly 102 installed in the seal 103, for example, avoiding the formation of steps between the side of the bracket 102c and the seal 103, which may cause a loose seal.

[0071] In one example, the heating portion is disposed on the top surface of the bracket 102c and at least partially covers the opening on the top surface of the bracket 102c. The first electrode and / or the second electrode extend from the top surface of the bracket 102c, around the side of the bracket 102c, and then to the bottom surface of the bracket 102c. Alternatively, the first electrode and / or the second electrode extend from the top surface of the bracket 102c, through the bracket 102c, and then to the bottom surface of the bracket 102c.

[0072] In one example, the heating portion includes a conductive track 102b1 that extends in a circuitous or meandering pattern between a first electrode and a second electrode. The conductive track 102b1 may include at least two periodically or repeatedly arranged track units. For example, the conductive track 102b1 may include a plurality of mesh-shaped track units. Alternatively, in other alternative embodiments, the conductive track 102b1 may have a variety of shapes, such as a wavy shape, a spiral shape, or a U-shape.

[0073] The heating portion also includes a tooth portion 102b2 extending outward from the conductive track 102b1 along the thickness direction of the atomizer 10. In this way, the heating portion spans the opening on the surface of the top of the bracket 102c along the thickness direction of the atomizer 10, thereby retaining the liquid-conducting element 102a within the first receiving chamber 102c1. The tooth portion 102b2 can receive heat from the conductive track 102b1 by conduction, thereby increasing the temperature field range and temperature field uniformity of the heating portion. The tooth portion 102b2 is slender. Alternatively, in some alternative embodiments, the tooth portion 102b2 has various shapes such as rectangle, trapezoid, circle, ellipse, polygon, etc.

[0074] The first electrode includes a first base portion 102b3 and a first electrical connection portion 102b4 connected to the first base portion 102b3. The second electrode includes a second base portion 102b5 and a second electrical connection portion 102b6 connected to the second base portion 102b5. The heating portion is coupled between the first base portion 102b3 and the second base portion 102b5 to form an electrical connection; namely, one end of the first base portion 102b3 is connected to the conductive trace 102b1 of the heating portion, and the other end of the first base portion 102b3 is connected to the first electrical connection portion 102b4. The second base portion 102b5 is similarly configured.

[0075] After assembly, the conductive track 102b1 is located at the opening of the top surface of the bracket 102c, and the tooth portion 102b2, the first base 102b3 and the second base 102b5 are all supported on the surface of the top of the bracket 102c, thereby basically covering the opening of the top wall of the first receiving cavity 102c1 and retaining the liquid-conducting element 102a in the first receiving cavity 102c1. A liquid hole 102b7 is provided on the first base 102b3, and a liquid hole 102b8 is provided on the second base 102b5; the liquid hole 102b7 and / or the liquid hole 102b8 are arranged close to the side of the bracket 102c. In further implementation, the top surface of the bracket 102c also has a protrusion 102c2 that cooperates with the liquid hole 102b7 and / or the liquid hole 102b8. The protrusion 102c2 can extend into the liquid hole. The protrusion 102c2 is flush with the surface of the heating element, ensuring that there is no obvious gap between the sealing member 103, thereby improving the sealing reliability between the atomizing assembly 102 and the sealing member 103. The first electrical connection portion 102b4 maintains contact with one side surface of the bracket 102c, and part of the first electrical connection portion 102b4 maintains contact with the surface of the bottom of the bracket 102c after being bent, that is, the first electrical connection portion 102b4 extends to the surface of the bottom of the bracket 102c and maintains contact. This part of the first electrical connection portion 102b4 is covered on the surface of the bottom of the bracket 102c and extends flatly, and after assembly, it is convenient to abut or weld with the electrode connector 105 to form conductivity, thereby facilitating the automated assembly of the atomizer component 102 and the electrode connector 105. Similarly, the second electrical connection portion 102b6 maintains contact with the other opposite side surface of the bracket 102c, and a portion of the second electrical connection portion 102b6 is bent and maintains contact with the surface of the bottom of the bracket 102c. This portion of the second electrical connection portion 102b6 also covers the surface of the bottom of the bracket 102c and extends flatly. After assembly, it is convenient for abutting or welding with the electrode connector 106 to form electrical conductivity, facilitating the automated assembly of the atomizer assembly 102 and the electrode connector 105. This structure can maintain the heating element 102b on the bracket 102c, thereby forming an integrated atomizer assembly 102 and facilitating automated assembly.

[0076] After assembly, first electrical connection portion 102b4 forms electrical conduction with electrode connector 105, and second electrical connection portion 102b6 forms electrical conduction with electrode connector 106, thereby directing current through heating element 102b. During use, current flows through the heating portion along the circuitous or serpentine conductive trace 102b1, generating heat through resistive Joule heating. Furthermore, current substantially does not flow through teeth 102b2.

[0077] In some specific embodiments, the heating element 102b is made of a sheet of resistive metal by cutting or etching, etc. For example, the heating element 102b is made of a resistive metal such as iron-chromium-aluminum alloy, nickel-chromium alloy, etc.

[0078] Seal 103 is made of a flexible material. Seal 103 and housing 101 define liquid storage chamber 101d. Seal 103 can be made of a flexible material such as silicone, thermoplastic elastomer, or thermoplastic rubber, but is preferably made of a single material, such as thermoplastic elastomer.

[0079] As shown in Figures 9 to 11, the seal 103 includes an upper end 103a (an end close to the liquid storage chamber 101d), a lower end 103b (an end away from the liquid storage chamber 101d), a main body 103c extending from the upper end 103a to the lower end 103b, a second receiving chamber 103d, a liquid transmission channel 103e, an aerosol transmission channel 103f and a cavity 103g.

[0080] The end surface of the upper end 103a has an opening connected to the liquid transmission channel 103e. This opening serves as a liquid inlet, and the liquid matrix stored in the liquid storage chamber 101d can flow into the liquid transmission channel 103e through this opening. The end surface of the upper end 103a also has an opening connected to the aerosol transmission channel 103f.

[0081] The end surface of the lower end 103b has an opening.

[0082] At least one flange 103c1 is provided on the outer surface of the body 103c near the upper end 103a, and at least one flange 103c2 is provided on the outer surface of the body 103c near the lower end 103b. Both flanges 103c1 and 103c2 are arranged around the outer circumference of the body 103c to form a raised ring. The number of flanges 103c1 is not limited; multiple flanges 103c1 can be provided at intervals on the outer surface of the body 103c; similar arrangements are made for flanges 103c2. Both flanges 103c1 and 103c2 maintain contact with the inner surface of the housing 101, thereby achieving a seal. In a preferred embodiment, four flanges 103c1 are provided on the outer surface of the body 103c near the upper end 103a. The four flanges 103c1 are arranged sequentially along the length of the atomizer 10, with two flanges 103c1 positioned immediately adjacent to the upper end 103a, and the other two flanges 103c1 spaced a certain distance apart from the other two flanges 103c1. Two to four flanges 103c2 are provided on the outer surface of the body 103c near the lower end 103b. The multiple flanges 103c2 are arranged sequentially along the length of the atomizer 10, with the flanges 103c2 positioned immediately adjacent to the lower end 103b.

[0083] The body 103c also has openings 103c3 on two opposing sidewalls along the thickness of the atomizer 10. Along the length of the atomizer 10, the openings 103c3 are located between the flanges 103c1 and 103c2. The openings 103c3 communicate with the cavity 103g via a through-hole 103d1. The openings 103c3 also communicate with the aerosol transmission channel 103f via a through-hole 103f2. The length of the openings 103c3 along the atomizer 10 is between 5 mm and 7 mm; in a preferred embodiment, between 5 mm and 6 mm; and in a further preferred embodiment, between 5.5 mm and 6 mm. The width of the openings 103c3 along the atomizer 10 is between 3 mm and 5 mm; in a preferred embodiment, between 3 mm and 4.5 mm; and in a further preferred embodiment, between 3.5 mm and 4.5 mm.

[0084] A liquid retention area is defined between the body 103c and the housing 101, located between the flanges 103c1 and 103c2, for retaining a portion of the liquid matrix from the second receiving chamber 103d or the aerosol transmission channel 103f. The liquid retention area includes capillary grooves 103c4 distributed on the outer surface of the body 103c. The capillary grooves 103c4 extend at least partially along the outer circumference of the body 103c. In a preferred embodiment, one end of the capillary grooves 103c4 communicates with the opening 103c3, and the other end of the capillary grooves 103c4 extends along the outer circumference of the body 103c and terminates at the opening 103c3. The number of capillary grooves 103c4 is not limited. A plurality of spaced capillary grooves 103c4 may be provided on the outer surface of the body 103c, and the plurality of spaced capillary grooves 103c4 may be connected (for example, by providing capillary grooves extending along the length of the atomizer 10 on the outer surface of the body 103c to connect the plurality of spaced capillary grooves 103c4). In a preferred embodiment, approximately 5 to 6 capillary grooves 103c4 are sequentially arranged along the length of the atomizer 10, and the capillary grooves 103c4 are spaced apart and not connected. The dimension of the capillary grooves 103c4 along the length of the atomizer 10 is between 0.4 mm and 0.6 mm, and the spacing between adjacent capillary grooves 103c4 is between 0.4 mm and 0.6 mm. The spacing distance between the capillary groove 103c4 and the flange 103c1 is smaller than the spacing distance between the capillary groove 103c4 and the flange 103c2, which is conducive to the storage of condensed liquid between the capillary groove 103c4 and the flange 103c2.

[0085] The second receiving cavity 103d is disposed in the body 103c. The second receiving cavity 103d is spaced apart from the opening of the lower end 103b to form a cavity 103g, which is communicated with the opening of the lower end 103b.

[0086] A liquid transfer channel 103e is disposed within the body 103c. One end of the liquid transfer channel 103e communicates with an opening on the end surface of the upper end 103a, and the other end communicates with the second receiving chamber 103d. The liquid transfer channel 103e provides a pathway for transferring liquid matrix stored in the liquid storage chamber 101d to the liquid-conducting element 102a. In a preferred embodiment, two liquid transfer channels 103e are symmetrically disposed within the body 103c along the width of the atomizer 10. This allows more liquid matrix to be directed more smoothly to the liquid-conducting element 102a.

[0087] The aerosol transmission channel 103f is disposed within the body 103c. One end of the aerosol transmission channel 103f is connected to the opening on the end surface of the upper end 103a, and the other end is connected to the second receiving chamber 103d. The aerosol transmission channel 103f is used to provide a channel for the aerosol generated by the atomization assembly 102 to be transmitted to the mouthpiece 101a. In a preferred embodiment, the aerosol transmission channel 103f is spaced apart from the liquid transmission channel 103e, and the aerosol transmission channel 103f is disposed between the two liquid transmission channels 103e.

[0088] The lower end of the aerosol transmission tube 101c can be inserted into the aerosol transmission channel 103f through the opening in the end face of the upper end 103a. After assembly, the seal 103 seals the aerosol transmission tube 101c. In further implementations, a stopper 103f1 is further provided within the aerosol transmission channel 103f to provide a stop for the other end of the aerosol transmission tube 101c. The stopper 103f1 comprises a bump disposed on the inner surface of the aerosol transmission channel 103f.

[0089] The atomizer assembly 102 can be assembled into the second receiving chamber 103d through the opening of the lower end 103b and the cavity 103g, that is, the bracket 102 is at least partially received in the second receiving chamber 103d. After assembly, the lower end of the aerosol transmission channel 103f is located near the surface of the top of the bracket 102c, that is, the top surface of the bracket 102c is arranged to face the aerosol transmission channel 103f; the heating element 102b is at least partially located between the top surface of the bracket 102c and the aerosol transmission channel 103f. The projection of the aerosol transmission channel 103f on the top surface of the bracket 102c and the projection of the heating element on the top surface of the bracket 102c at least partially overlap. Specifically, one end surface of the lower end of the aerosol transmission channel 103f along the width direction of the atomizer 10 abuts the first base portion 102b3, and the other end surface of the lower end of the aerosol transmission channel 103f along the width direction of the atomizer 10 abuts the second base portion 102b5; both end surfaces of the lower end of the aerosol transmission channel 103f along the thickness direction of the atomizer 10 abut against the tooth portion 102b2. With this structure, on the one hand, the heating portion, the first base portion 102b3, and the second base portion 102b5 can be maintained on the top wall of the bracket 102c; on the other hand, the heating portion of the heating element 102b can be located between the two end surfaces of the lower end of the aerosol transmission channel 103f along the width direction of the atomizer 10, and the aerosol after heating and atomization can flow directly into the aerosol transmission channel 103f. The temperatures of the teeth 102b2, the first base 102b3 and the second base 102b5 are lower than those of the conductive track 102b1, which can effectively reduce the heat transferred to the aerosol transmission channel 103f.

[0090] After assembly, a portion of the liquid-conducting element 102a is positioned near the lower end of the liquid delivery channel 103e to absorb the liquid matrix. The first base portion 102b3 or the second base portion 102b5 is sandwiched between the lower end of the liquid delivery channel 103e and the portion of the liquid-conducting element 102a. The liquid passage provides a path for the liquid matrix to pass from the lower end of the liquid delivery channel 103e to the liquid-conducting element 102a. Specifically, the liquid passage allows the heating element 102b to at least partially avoid the liquid-conducting element 102a, thereby enabling the liquid-conducting element 102a to receive the liquid matrix through the liquid delivery channel 103e. Specifically, the liquid passage hole 102b7 is located between one end surface of the lower end of the aerosol transmission channel 103f along the width of the atomizer 10 and one inner surface of the second receiving chamber 103d along the width of the atomizer 10. The liquid passage hole 102b8 is located between the other end surface of the lower end of the aerosol transmission channel 103f along the width of the atomizer 10 and the other inner surface of the second receiving chamber 103d along the width of the atomizer 10. With this structure, the liquid matrix in the left liquid transmission channel 103e can be transferred to the liquid-conducting element 102a through the liquid passage hole 102b7; the liquid matrix in the right liquid transmission channel 103e can be transferred to the liquid-conducting element 102a through the liquid passage hole 102b8. For details, please refer to the liquid matrix transfer path R1 in Figure 4.

[0091] It is understood that the above structural design allows the liquid matrix to be transferred to the liquid-conducting element 102a through the top surface of the bracket 102c. In other examples, it is also feasible to transfer the liquid matrix to the liquid-conducting element 102a through the side of the bracket 102c. For example, the side of the bracket 102c is provided with a liquid hole or groove, so that the liquid-conducting element 102a can receive the liquid matrix through the liquid transmission channel 103e.

[0092] In one example, a ventilation channel is provided between the inner surface of the second receiving chamber 103d and the outer surface of the bracket 102c, or between the inner surface of the second receiving chamber 103d and the first electrical connection portion 102b4 or the second electrical connection portion 102b6 abutting against the side wall of the bracket 102c, and one end of the ventilation channel is connected to the cavity 103g and the other end is connected to the liquid transmission channel 103e. Through the ventilation channel, air can be added to the liquid storage chamber 101d to relieve the negative pressure of the liquid storage chamber 101d, so that the liquid matrix in the liquid storage chamber 101d can be smoothly transferred to the liquid guiding element 102a. In a specific implementation, the ventilation channel includes an air flow groove 103d2 provided on the inner surface of the second receiving chamber 103d, for example, on another inner surface along the width direction of the atomizer 10.

[0093] The bottom cover 104 is detachably coupled to the opening 101b at the distal end of the housing 101, thereby defining a housing of the atomizer together with the housing 101. In a preferred embodiment, the bottom cover 104 is snap-fitted to the housing 101.

[0094] The bottom cover 104 is provided with a first electrode hole 104a and a second electrode hole 104b, and is provided with an electrode connector 105 and an electrode connector 106, which are mounted in a one-to-one correspondence. One end of the electrode connector 105 maintains contact with the first electrical connection portion 102b4 to form an electrical connection, while the other end of the electrode connector 105 is exposed on the bottom cover 104. One end of the electrode connector 106 maintains contact with the second electrical connection portion 102b6 to form an electrical connection, while the other end of the electrode connector 106 is exposed on the bottom cover 104. Furthermore, the electrode connectors 105 and 106 can also support the atomizer assembly 102, thereby maintaining the atomizer assembly 102 within the second receiving cavity 103d.

[0095] In one example, both the electrode connector 105 and the electrode connector 106 are non-elastic electrodes. When the electrode connector 105 and the electrode connector 106 are assembled to the atomizer 10, the electrode connector 105 and the electrode connector 106 are supported on the bottom cover 104 and extend linearly toward the atomizer assembly 102. Due to the elastic compression of the seal 103, the atomizer assembly 102 can provide an elastic force downward or opposite to the assembly direction to the electrode connector 105 or the electrode connector 106, so that one end of the electrode connector 105 or the electrode connector 106 maintains good contact with the electrical connection portion of the heating element 102b and is not easily misaligned.

[0096] An air inlet 104c is also provided on the bottom cover 104. External air enters the atomizer 10 through the air inlet 104c, and can flow into the opening 103c3 through the through hole 103d1, that is, between the sealing member 103 and the inner surface of the outer shell 101, and then flows into the aerosol transmission channel 103f through the through hole 103f2, and after mixing with the aerosol generated by heating and atomization of the heating element 102b, it flows out from the mouthpiece 101a through the aerosol transmission tube 101c. For details, please refer to the air flow path R2 shown in Figure 5. As can be seen from the figure, the opening 103c3 is provided between the flange 103c1 and the flange 103c2, and the flange 103c1 and the flange 103c2 are both in contact with the inner surface of the outer shell 101 to achieve sealing; in this way, it can be ensured that the airflow flows into the aerosol transmission channel 103f through the opening 103c3.

[0097] The bottom cover 104 is further provided with a collecting chamber 104 d . The first electrode hole 104 a , the second electrode hole 104 b and the air inlet 104 c all protrude from the collecting chamber 104 d . The collecting chamber 104 d is used to collect the liquid matrix to prevent the liquid matrix from flowing toward the power supply assembly 20 .

[0098] The outer surface of the bottom cover 104 has steps 104e and 104f. After assembly, the upper end of the bottom cover 104 extends into the cavity 103g of the seal 103, so that part of the seal 103 is sandwiched between the bottom cover 104 and the housing 101. The end surface of the lower end 103b of the seal 103 abuts against the step 104e, and the end surface of the distal end of the housing 101 abuts against the step 104f.
