[0053] Figure 1 It is a schematic diagram of the electronic atomization device provided in an embodiment of the present application.

[0054] like Figure 1 As shown, 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 interference fit, snap connection, or magnetic connection.

[0055] The nebulizer 10 is used to heat and nebulize a liquid base to generate an aerosol.

[0056] The power supply assembly 20 includes a battery cell 21 and a circuit 22 .

[0057] The battery cell 21 provides power for operating the electronic atomization device 100. The battery cell 21 may be a rechargeable battery cell or a disposable battery cell.

[0058] The circuit 22 can control the overall operation of the electronic atomization device 100. The circuit 22 not only controls the operation of the battery cell 21 and the atomizer 10, but also controls the operation of other components in the electronic atomization device 100.

[0059] Figures 2 to 13 The schematic diagram of the structure of an atomizer of an embodiment is shown; in the atomizer 10 of this embodiment, it includes:

[0060] The housing 101 has a mouthpiece 101a at the proximal end and an opening 101b at the distal end. The mouthpiece 101a can be used as an aerosol outlet, and the user or the 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 in 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, and the liquid storage chamber 101d is connected to the opening 101b. The atomization assembly 102 and the sealing member 103 can be assembled into the housing 101 through the opening 101b.

[0061] 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.

[0062] The atomizing assembly 102 includes a liquid guiding element 102a, a heating element 102b and a bracket 102c.

[0063] The liquid guiding element 102a is used to absorb the liquid matrix from the liquid storage chamber 101d and transfer the liquid matrix to the heating element 102b. The liquid guiding element 102a is block-shaped. The liquid guiding element 102a is arranged along the width direction ( Figure 2 The size of the liquid-conducting element 102a along the length direction of the atomizer 10 ( Figure 2 in the X direction) or the thickness direction ( Figure 2 The dimension of the liquid-conducting element 102a along the thickness direction of the atomizer 10 is greater than the dimension 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 a porous capillary fiber element such as a flexible cotton fiber, a non-woven fiber, or a sponge. In another example, the liquid-conducting element 102a is a rigid porous body, such as a porous ceramic body, a porous glass, or a foamed metal.

[0064] The bracket 102c is roughly block-shaped. The surface of the top of the bracket 102c is arranged facing the liquid storage chamber 101d, and the surface of the bottom of the bracket 102c is arranged facing the bottom cover 104. The bracket 102c has a receiving chamber 102c1, and the surface of the top of the bracket 102c has an opening connected to the receiving chamber 102c1. The receiving chamber 102c1 is used to receive or accommodate the liquid-conducting element 102a. The receiving chamber 102c1 can receive the liquid matrix absorbed by the liquid-conducting element 102a, which is beneficial for the liquid-conducting element 102a to retain the liquid matrix and reduce the probability of the liquid matrix leaking to the bottom cover 104. The shape of the receiving chamber 102c1 is adapted to the shape of the liquid-conducting element 102a. The dimension of the liquid-conducting element 102a along the length direction of the atomizer 10 is slightly larger than the dimension of the accommodating cavity 102c1 along the length direction of the atomizer 10, for example, slightly larger than 0.5 to 1 mm. In this way, part of the liquid-conducting element 102a protrudes from the opening on the top surface of the bracket 102c, which is beneficial for the liquid-conducting element 102a to maintain contact with the heating part of the heating element 102b, thereby forming a good liquid-conducting relationship.

[0065] The heating element 102b is used to heat the atomized liquid substrate to generate an aerosol.

[0066] The heating element 102b includes a first electrode, a second electrode, and a heating portion connected to the first electrode and the second electrode. The first electrode and the second electrode are arranged at intervals along the width direction of the atomizer 10 to increase the area of ​​the heating portion, and the heating portion extends between the first electrode and the second electrode. In use, the first electrode and the second electrode define an electrical connection area of ​​the heating element 102b, and the heating portion defines a heating area of ​​the heating element 102b.

[0067] 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, resulting in poor sealing.

[0068] In one example, the heating portion is disposed on the surface of the top of the support 102c and at least partially covers the opening on the surface of the top of the support 102c. The first electrode and / or the second electrode extend from the surface of the top of the support 102c around the side of the support 102c to the surface of the bottom of the support 102c, or the first electrode and / or the second electrode extend from the surface of the top of the support 102c through the support 102c to the surface of the bottom of the support 102c.

[0069] In one example, the heating portion includes a conductive track 102b1 extending in a circuitous or meandering manner between the first electrode and the second electrode; the conductive track 102b1 may include at least two track units that are presented periodically or repeatedly, for example, the conductive track 102b1 may include a plurality of track units in a mesh shape. Alternatively, in some other variant embodiments, the conductive track 102b1 may also have more shapes, such as a wave shape, a spiral shape, a U shape, etc.

[0070] The heating portion also includes a tooth portion 102b2 extending outward from the conductive track 102b1 along the thickness direction of the atomizer 10, so that 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 keeping the liquid-conducting element 102a in the 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. Or in some other variant embodiments, the tooth portion 102b2 is a variety of shapes such as a rectangle, a trapezoid, a circle, an ellipse, a polygon, etc.

[0071] The first electrode includes a first base 102b3 and a first electrical connection portion 102b4 connected to the first base 102b3. The second electrode includes a second base 102b5 and a second electrical connection portion 102b6 connected to the second base 102b5. The heating portion is combined between the first base 102b3 and the second base 102b5 to form an electrical connection; that is, one end of the first base 102b3 is connected to the conductive track 102b1 of the heating portion, and the other end of the first base 102b3 is connected to the first electrical connection portion 102b4, and the second base 102b5 is similarly configured.

[0072] 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 portion 102b3 and the second base portion 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 receiving cavity 102c1 and keeping the liquid-conducting element 102a in the 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 provided 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, and 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 drop between the sealing member 103, thereby improving the sealing reliability between the atomization assembly 102 and the sealing member 103. The first electrical connection portion 102b4 maintains contact with one side surface of the bracket 102c, and a portion 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 portion of the first electrical connection portion 102b4 covers 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 atomization component 102 and the electrode connector 105. Similarly, the second electrical connection portion 102b6 is in contact with the other opposite side of the bracket 102c, and part of the second electrical connection portion 102b6 is in contact with the surface of the bottom of the bracket 102c after being bent. This part of the second electrical connection portion 102b6 is also 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 106 to form electrical conduction, which is convenient for the automated assembly of the atomizer assembly 102 and the electrode connector 105. With such a structure, the heating element 102b can be kept on the bracket 102c, so that the atomizer assembly 102 is integrated, which is convenient for automated assembly.

[0073] After assembly, the first electrical connection portion 102b4 forms a conductive connection with the electrode connection member 105, and the second electrical connection portion 102b6 forms a conductive connection with the electrode connection member 106, thereby guiding the current on the heating element 102b. In use, the current flows through the heating portion along the circuitous or meandering conductive track 102b1 to form resistive Joule heat and generate heat; and the current basically does not flow through the tooth portion 102b2.

[0074] 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.

[0075] The sealing member 103 is made of a flexible material. The sealing member 103 and the housing 101 define a liquid storage chamber 101d. The sealing member 103 can be made of a flexible material such as silicone, thermoplastic elastomer (Thermo-Plastic-Elastomer) or thermoplastic rubber (Thermo-Plastic-Rubber), and is preferably made of a single material, such as thermoplastic elastomer (Thermo-Plastic-Elastomer).

[0076] like Figure 9-11 As shown, 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 receiving chamber 103d, a liquid transmission channel 103e, an aerosol transmission channel 103f and a cavity 103g.

[0077] The end surface of the upper end 103a has an opening connected to the liquid transmission channel 103e, and the opening serves as a liquid inlet, through which the liquid matrix stored in the liquid storage chamber 101d can flow into the liquid transmission channel 103e. The end surface of the upper end 103a also has an opening connected to the aerosol transmission channel 103f.

[0078] The end surface of the lower end 103b has an opening.

[0079] At least one flange 103c1 is provided on the outer surface of the body 103c close to the upper end 103a, and at least one flange 103c2 is provided on the outer surface of the body 103c close to the lower end 103b. Both the flange 103c1 and the flange 103c2 are arranged around the outer circumference of the body 103c to form a convex ring. The number of flanges 103c1 is not limited, and multiple flanges 103c1 can be provided on the outer surface of the body 103c at intervals; the flange 103c2 is similar. Both the flange 103c1 and the flange 103c2 are in contact with the inner surface of the housing 101, thereby achieving sealing. In a preferred embodiment, four flanges 103c1 are arranged on the outer surface of the body 103c near the upper end 103a, and the four flanges 103c1 are arranged in sequence along the length direction of the atomizer 10, two of which are arranged close to the upper end 103a, and the other two flanges 103c1 are kept at a certain distance from the other two flanges 103c1. Two to four flanges 103c2 are arranged on the outer surface of the body 103c near the lower end 103b, and the multiple flanges 103c2 are arranged in sequence along the length direction of the atomizer 10, and the flanges 103c2 are arranged close to the lower end 103b.

[0080] The body 103c is also provided with openings 103c3 on two opposite side walls along the thickness direction of the atomizer 10. The opening 103c3 is provided between the flange 103c1 and the flange 103c2 along the length direction of the atomizer 10. The opening 103c3 is communicated with the cavity 103g through the through hole 103d1, and the opening 103c3 is also communicated with the aerosol transmission channel 103f through the through hole 103f2. The size of the opening 103c3 along the length direction of the atomizer 10 is between 5mm and 7mm; in a preferred implementation, between 5mm and 6mm; in a further preferred implementation, between 5.5mm and 6mm. The size of the opening 103c3 along the width direction of the atomizer 10 is between 3mm and 5mm; in a preferred implementation, between 3mm and 4.5mm; in a further preferred implementation, between 3.5mm and 4.5mm.

[0081] A liquid holding area for holding a portion of the liquid matrix from the receiving chamber 103d or the aerosol transmission channel 103f is defined between the body 103c located between the flange 103c1 and the flange 103c2 and the housing 101. The liquid holding area includes capillary grooves 103c4 distributed on the outer surface of the body 103c, and the capillary grooves 103c4 extend at least partially along the outer periphery of the body 103c; in a preferred embodiment, one end of the capillary groove 103c4 is connected to the opening 103c3, and the other end of the capillary groove 103c4 extends along the outer periphery of the body 103c and terminates at the opening 103c3. The number of the capillary grooves 103c4 is not limited, and 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 a capillary groove extending along the length direction of the atomizer 10 on the outer surface of the body 103c to connect the plurality of spaced capillary grooves 103c4). In a preferred implementation, about 5 to 6 capillary grooves 103c4 are sequentially arranged along the length direction of the atomizer 10, and the capillary grooves 103c4 are arranged to be spaced apart and not connected. The size of the capillary grooves 103c4 along the length direction of the atomizer 10 is between 0.4 mm and 0.6 mm, and the spacing distance 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, so that the condensed liquid is stored between the capillary groove 103c4 and the flange 103c2.

[0082] The receiving cavity 103d is disposed in the body 103c. The receiving cavity 103d is spaced from the opening of the lower end 103b to form a cavity 103g, and the cavity 103g is communicated with the opening of the lower end 103b.

[0083] The liquid transmission channel 103e is arranged in the body 103c. One end of the liquid transmission channel 103e is communicated with the opening of the end surface of the upper end 103a, and the other end is communicated with the receiving chamber 103d. The liquid transmission channel 103e provides a channel for the liquid matrix stored in the liquid storage chamber 101d to be transferred to the liquid guiding element 102a. In a preferred embodiment, the two liquid transmission channels 103e are symmetrically arranged in the body 103c along the width direction of the atomizer 10. In this way, the liquid matrix can be guided to the liquid guiding element 102a more and more smoothly.

[0084] The aerosol transmission channel 103f is arranged in the body 103c. One end of the aerosol transmission channel 103f is connected to the opening of the end face of the upper end 103a, and the other end is connected to the receiving chamber 103d. The aerosol transmission channel 103f is used to provide a channel for the aerosol generated by the atomization component 102 to be transmitted to the mouthpiece 101a. In a preferred embodiment, the aerosol transmission channel 103f is arranged at intervals from the liquid transmission channel 103e, and the aerosol transmission channel 103f is arranged between the two liquid transmission channels 103e.

[0085] The lower end of the aerosol transmission tube 101c can be inserted into the aerosol transmission channel 103f through the opening of the end surface of the upper end 103a, and the sealing member 103 seals the aerosol transmission tube 101c after assembly. In a further implementation, a stopper 103f1 is further provided in the aerosol transmission channel 103f to provide a stop for the other end of the aerosol transmission tube 101c; the stopper 103f1 includes a convex block provided on the inner surface of the aerosol transmission channel 103f.

[0086] The atomizer assembly 102 can be assembled into the receiving cavity 103d through the opening of the lower end 103b and the cavity 103g, that is, the bracket 102 is at least partially accommodated in the receiving cavity 103d. After assembly, the lower end of the aerosol transmission channel 103f is arranged near the surface of the top of the bracket 102c, that is, the surface of the top of the bracket 102c is arranged toward the aerosol transmission channel 103f; the heating element 102b is at least partially located between the surface of the top of the bracket 102c and the aerosol transmission channel 103f. The projection of the aerosol transmission channel 103f on the surface of the top of the bracket 102c and the projection of the heating part on the surface of the top 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 against the first base 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 against the second base 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 such a structure, on the one hand, the heating part, the first base 102b3 and the second base 102b5 can be maintained on the top wall of the bracket 102c; on the other hand, the heating part 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 directly flow 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.

[0087] After assembly, part of the liquid-conducting element 102a is disposed near the lower end of the liquid transmission channel 103e to absorb the liquid matrix. The first base 102b3 or the second base 102b5 is sandwiched between the lower end of the liquid transmission channel 103e and part of the liquid-conducting element 102a. The liquid-passing hole provides a channel for the liquid matrix to be transferred from the lower end of the liquid transmission channel 103e to the liquid-conducting element 102a. Specifically, the liquid-passing hole allows the heating element 102b to at least partially avoid the liquid-conducting element 102a, thereby allowing the liquid-conducting element 102a to receive the liquid matrix through the liquid transmission channel 103e. Specifically, the liquid-passing hole 102b7 is located between an end face of the lower end of the aerosol transmission channel 103f along the width direction of the atomizer 10 and an inner surface of the receiving chamber 103d along the width direction of the atomizer 10, and the liquid-passing hole 102b8 is located between another end face of the lower end of the aerosol transmission channel 103f along the width direction of the atomizer 10 and another inner surface of the receiving chamber 103d along the width direction of the atomizer 10. With such a structure, the liquid matrix in the liquid transmission channel 103e on the left side can be transferred to the liquid-conducting element 102a through the liquid-passing hole 102b7; the liquid matrix in the liquid transmission channel 103e on the right side can be transferred to the liquid-conducting element 102a through the liquid-passing hole 102b8. For details, please refer to Figure 4 The transfer path R1 of the liquid matrix.

[0088] It is understandable that the above structural design allows the liquid matrix to be transferred to the liquid-conducting element 102a through the surface of the top 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, a liquid hole or groove is provided on the side of the bracket 102c, so that the liquid-conducting element 102a can receive the liquid matrix through the liquid transmission channel 103e.

[0089] In one example, there is a ventilation channel between the inner surface of the receiving chamber 103d and the outer surface of the bracket 102c, or between the inner surface of the 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, 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 of the liquid storage chamber 101d can be smoothly transferred to the liquid guide element 102a. In a specific implementation, the ventilation channel includes an air flow groove 103d2 arranged on the inner surface of the receiving chamber 103d, for example, on another inner surface along the width direction of the atomizer 10.

[0090] The bottom cover 104 is detachably coupled to the opening 101b at the far 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-connected to the housing 101.

[0091] The bottom cover 104 is provided with a first electrode hole 104a and a second electrode hole 104b, and an electrode connector 105 and an electrode connector 106 are installed one by one. One end of the electrode connector 105 is in contact with the first electrical connection portion 102b4 to form an electrical connection, and the other end of the electrode connector 105 is exposed on the bottom cover 104; one end of the electrode connector 106 is in contact with the second electrical connection portion 102b6 to form an electrical connection, and the other end of the electrode connector 106 is exposed on the bottom cover 104. Further, the electrode connector 105 and the electrode connector 106 can also support the atomizer assembly 102, so that the atomizer assembly 102 is kept in the receiving cavity 103d.

[0092] 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 straight 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 part of the heating element 102b and is not easily misaligned.

[0093] The bottom cover 104 is also provided with an air inlet 104c. External air enters the atomizer 10 through the air inlet 104c, flows into the opening 103c3 through the through hole 103d1, that is, between the seal 103 and the inner surface of the housing 101, and then flows into the aerosol transmission channel 103f through the through hole 103f2, mixes with the aerosol generated by heating and atomization of the heating element 102b, and then flows out from the mouthpiece 101a through the aerosol transmission tube 101c. For details, please refer to Figure 5 As shown in the airflow path R2 in FIG. As can be seen from the figure, the opening 103c3 is arranged 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 housing 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.

[0094] The bottom cover 104 is further provided with a collecting chamber 104 d , and 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 to the power source assembly 20 .

[0095] The outer surface of the bottom cover 104 has a step 104e and a step 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 far end of the housing 101 abuts against the step 104f.
