[0055] Figures 2 to 16 The schematic diagram of the structure of an atomizer of an embodiment is shown; in the atomizer 10 of this embodiment, it includes:

[0056] 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.

[0057] The atomizer core 102 includes a liquid guiding element 102a and a heating element 102b.

[0058] The liquid-conducting element 102a is block-shaped or plate-shaped. The liquid-conducting element 102a extends along the width direction of the atomizer 10 ( 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 2The size of the liquid-conducting element 102a along the length direction of the atomizer 10 is greater than the size of the liquid-conducting element 102a along the thickness direction of the atomizer 10. The liquid-conducting element 102a is preferably a rigid porous body, such as a porous ceramic body, porous glass or foam metal. The liquid-conducting element 102a has an atomizing surface 102a1 and a liquid absorbing surface 102a2 that are opposite to each other along the thickness direction of the atomizer 10. The liquid absorbing surface 102a2 is used to absorb the liquid matrix from the liquid storage chamber 101d and transfer the liquid matrix to the atomizing surface 102a1.

[0059] The heating element 102b is formed on the atomizing surface 102a1 of the liquid guiding element 102a, and the heating element 102b can be formed on the atomizing surface 102a1 by mounting, printing, deposition, etc. The heating element 102b is used to heat the atomized liquid matrix to generate an aerosol.

[0060] The heating element 102b includes a first electrode 102b1, a second electrode 102b2, and a heating portion 102b3 connected to the first electrode 102b1 and the second electrode 102b2. The first electrode 102b1 and the second electrode 102b2 are arranged at intervals along the width direction of the atomizer 10, and the heating portion 102b3 extends between the first electrode 102b1 and the second electrode 102b2. In use, the first electrode 102b1 and the second electrode 102b2 define an electrical connection area of ​​the heating element 102b, and the heating portion 102b3 defines a heating area of ​​the heating element 102b.

[0061] In one example, the heating portion 102b3 includes a conductive track that meanders or extends between the first electrode 102b1 and the second electrode 102b2; in use, current flows through the heating portion 102b3 along the meandering or winding conductive track to form resistive Joule heat and generate heat. The conductive track may include at least two track units that are presented periodically or repeatedly, for example, the conductive track may include several U-shaped track units. Or in some other variant embodiments, the conductive track may also have more shapes, such as a waveform shape, etc.

[0062] The bracket 103 is made of a hard material, such as plastic, and is provided with a connecting cavity 103a and a receiving cavity 103b connected to the connecting cavity 103a.

[0063] The lower end of the aerosol transmission tube 101c is inserted into the connecting cavity 103a. The aerosol transmission tube 101c defines, or the aerosol transmission tube 101c and the connecting cavity 103a jointly define, a channel for providing aerosol generated by atomization of the atomization core 102 to be transmitted to the mouthpiece 101a. In a further implementation, a stopper 103a1 is further provided in the connecting cavity 103a to provide a stop for the lower end of the aerosol transmission tube 101c; the stopper 103a1 includes a protrusion provided on the inner surface of the connecting cavity 103a.

[0064] The atomizer core 102 can be assembled into the receiving cavity 103b through the opening of the lower end surface of the bracket 103. The liquid absorption surface 102a2 of the liquid-conducting element 102a is arranged close to and facing the first side wall of the bracket 103 along the thickness direction of the atomizer 10. The first side wall defines at least part of the boundary of the receiving cavity 103b. The first side wall is provided with a liquid inlet 103c. The outer surface of the first side wall is at least partially spaced from the inner surface of the shell 101. The liquid matrix in the liquid storage cavity 101d can flow into the gap between the outer surface of the first side wall and the inner surface of the shell 101, and then flow from the liquid inlet 103c into the liquid absorption surface 102a2 of the liquid-conducting element 102a (refer to Figure 5 The bracket 103 has a second side wall arranged along the thickness direction of the atomizer 10 and opposite to the first side wall. The second side wall is provided with an opening communicating with the receiving cavity 103b, through which the atomizer core 102, the sealing member 104 and other components can be easily installed.

[0065] In a further implementation, a liquid inlet groove 103d is provided on the outer surface of the first side wall, and the liquid inlet groove 103d extends from the liquid inlet port 103c toward the liquid storage cavity 101d. In this way, the gap between the outer surface of the first side wall and the inner surface of the housing 101 can be increased, which is conducive to the liquid matrix flowing into the gap between the outer surface of the first side wall and the inner surface of the housing 101.

[0066] The atomizing surface 102a1 of the liquid-conducting element 102a is disposed facing away from the first side wall and exposed in the receiving cavity 103b. The aerosol generated by the heating element 102b heating the atomized liquid matrix can be released in the receiving cavity 103b and then transmitted to the mouthpiece 101a through the connecting cavity 103a and the aerosol transmission tube 101c.

[0067] In a further implementation, the bracket 103 is further provided with a ventilation groove 103e and a ventilation hole 103f. The ventilation groove 103e is arranged on the inner surface of the first side wall of the bracket 103, and the ventilation hole 103f is arranged on the stopper 103a1. One end of the ventilation groove 103e is communicated with the liquid inlet 103c, and the other end of the ventilation groove 103e is arranged near one end of the ventilation hole 103f, and the other end of the ventilation hole 103f passes through the stopper 103a1, thereby communicating with the connecting cavity 103a.

[0068] In a further implementation, the bracket 103 is further provided with a connecting portion 103g connected to the base 108. Preferably, the connecting portion 103g is a snap-fitting hole connected to the base 108.

[0069] The seal is made of a flexible material. The seal can be made of a flexible material such as silicone, thermoplastic elastomer (Thermo-Plastic-Elastomer) or thermoplastic rubber (Thermo-Plastic-Rubber), preferably made of a single material, such as thermoplastic elastomer (Thermo-Plastic-Elastomer). The seal includes a seal 104, a seal 105 (a first seal), a seal 106 (a second seal) and a seal 107.

[0070] The seal 104 includes a first part 104a and a second part 104b connected to the first part 104a. The first part 104a is arranged between the aerosol transmission tube 101c and the connecting cavity 103a, so as to seal the gap between the aerosol transmission tube 101c and the connecting cavity 103a. The second part 104b is sleeved on the side wall of the bracket 103, and the second part 104b has a structural design corresponding to the side wall of the bracket 103, for example, a through hole 104c corresponding to the liquid inlet 103c and the liquid inlet groove 103d is arranged on one side wall, and a corresponding opening is arranged on the other side wall. The difference is that the outer surface of the second part 104b is also provided with a sealing rib 104b1; after assembly, the sealing rib 104b1 abuts against the inner surface of the outer shell 101, so as to seal the gap between the outer surface of the side wall of the bracket 103 and the inner surface of the outer shell 101.

[0071] The sealing member 105 is received in the receiving cavity 103 b and is at least partially disposed between the liquid absorbing surface 102 a 2 of the liquid guiding element 102 a and the first side wall of the bracket 103 along the thickness direction of the atomizer 10 .

[0072] The sealing member 105 includes a mounting portion 105a disposed between the liquid absorbing surface 102a2 and the first side wall of the bracket 103. The mounting portion 105a is generally plate-shaped or block-shaped, and a through hole 105a1 is provided on the mounting portion 105a. The liquid matrix flowing in from the liquid inlet 103c can flow into the liquid absorbing surface 102a2 of the liquid guiding element 102a through the through hole 105a1; as shown in the figure, there are two through holes 105a1 arranged at intervals. The mounting portion 105a is also provided with a sealing rib 105a2, which is arranged around the through hole 105a1 or arranged along the periphery of the through hole 105a1; after assembly, the sealing rib 105a2 abuts against the liquid absorbing surface 102a2, thereby forming a good sealing effect.

[0073] The seal 105 further comprises arms 105 b and 105 c extending from the mounting portion 105 a toward the first side wall away from the bracket 103 . The arms 105 b and 105 c abut against the side of the liquid guiding element 102 a , and the atomizer core 102 can be embedded in or retained in the seal 105 .

[0074] In a further implementation, a limit block 105b1 is further provided on the arm 105b, and the limit block 105b1 abuts against the atomization surface 102a1 of the liquid guiding element 102a, thereby clamping the liquid guiding element 102a or the atomization core 102 in the seal 105, that is, limiting the liquid guiding element 102a or the atomization core 102 from moving outward or in a direction away from the first side wall of the bracket 103.

[0075] In further implementation, a ventilation groove 105d is further provided on the top wall of the mounting portion 105a, and the ventilation groove 105d is formed by two protrusions protruding from the top wall of the mounting portion 105a. One end of the ventilation groove 105d is connected to the other end of the ventilation groove 103e, and the other end of the ventilation groove 105d is connected to one end of the ventilation hole 103f.

[0076] After assembly, the ventilation holes 103f, the ventilation grooves 105d and the ventilation grooves 103e define a ventilation channel. When the liquid matrix in the liquid storage chamber 101d forms a negative pressure due to consumption, the external air can flow into the gap between the outer surface of the first side wall of the bracket 103 and the inner surface of the shell 101 through the ventilation channel (as shown in the ventilation path R3 in the reference figure), and then flow into the liquid storage chamber 101d, thereby alleviating or balancing the negative pressure of the liquid storage chamber 101d, so that the liquid matrix in the liquid storage chamber 101d can smoothly flow to the liquid absorption surface 102a2 of the liquid guide element 102a.

[0077] The sealing member 106 is disposed in the receiving cavity 103b of the bracket 103. The sealing member 106 is disposed at the opening on the second side wall of the bracket 103, thereby sealing the opening on the second side wall of the bracket 103. The sealing member 106 is spaced apart from the atomizing surface 102a1 of the liquid guiding element 102a or the heating element 102b, and the space between the sealing member 106 and the atomizing surface 102a1 of the liquid guiding element 102a or the heating element 102b defines an atomizing cavity. The aerosol generated by the heating element 102b heating the atomized liquid matrix can be released in the atomizing cavity, and then transmitted to the mouthpiece 101a through the connecting cavity 103a and the aerosol transmission tube 101c.

[0078] In a preferred embodiment, the sealing member 106 has a groove 106a. The groove 106a can increase the volume of the atomizing chamber on the one hand, and facilitate the communication between the atomizing chamber, the connecting chamber 103a and the air inlet on the other hand.

[0079] The top surface of the seal 107 abuts against the bracket 103 and the seal 106 to form a seal. The top surface of the seal 107 has a first through hole 107a, which is aligned with and connected to the groove 106a; in a preferred embodiment, the top surface of the seal 107 is symmetrically provided with two first through holes 107a along the thickness direction of the atomizer 10, so that blind installation can be achieved. The top surface of the seal 107 is also provided with a second through hole 107b and a third through hole 107c, and the number of the second through hole 107b and the number of the third through hole 107c are both two.

[0080] The base 108 is provided with a step 108a and a step 108b. After assembly, the upper end of the base 108 extends into the seal 107, and the end surface of the lower end of the seal 107 abuts against the step 108a, so that part of the seal 107 is sandwiched between the base 108 and the housing 101, thereby forming a seal; the end surface of the far end of the housing 101 abuts against the step 108b.

[0081] The base 108 is also provided with an air inlet 108c. External air enters the base 108 through the air inlet 108c, flows into the atomization chamber through the first through hole 107a, and then carries the heating element 102b to heat the aerosol generated by atomization, and is transmitted to the mouthpiece 101a through the connecting chamber 103a and the aerosol transmission tube 101c (see the air flow path R2 in the figure). Figure 5 It can be seen that the first through hole 107 a is arranged to deviate from the air inlet 108 c , so that the liquid matrix or condensate in the atomization chamber can be prevented from falling into the air inlet 108 c and leaking out of the atomizer 10 .

[0082] The base 108 is also provided with two electrode holes 108d. One end of the electrode connector 110 passes through one electrode hole 108d and one second through hole 107b and then keeps contact with the first electrode 102b1 to form an electrical connection. The other end of the electrode connector 110 is exposed on the base 108 and forms an electrical connection with the battery cell 21 when the atomizer 10 and the power supply assembly 20 are connected. Similarly, one end of the electrode connector 111 passes through another electrode hole 108d and another second through hole 107b and then keeps contact with the second electrode 102b2 to form an electrical connection. The other end of the electrode connector 111 is exposed on the base 108 and then forms an electrical connection with the battery cell 21 when the atomizer 10 and the power supply assembly 20 are connected.

[0083] The base 108 is further provided with a connecting portion 108e. The connecting portion 108e passes through the third through hole 107c and is connected to the connecting portion 103g of the bracket 103. Preferably, the connecting portion 108e is a snap-fitting member snap-fitted to the bracket 103, so that the base 108 is integrated with the bracket 103 and other components.

[0084] The base 108 is also provided with a collecting chamber 108f, and the air inlet 108c and the electrode hole 108d both protrude from the collecting chamber 108f. The collecting chamber 108f is used to collect liquid matrix or condensate to prevent the liquid matrix or condensate from leaking out of the atomizer 10 or flowing to the power supply assembly 20.

[0085] The bottom cover 109 is detachably coupled to the housing 101, and defines a housing of the atomizer together with the housing 101. In a preferred embodiment, the bottom cover 109 is snap-connected to the housing 101. It is understandable that the bottom cover 109 is correspondingly provided with an air inlet and an electrode hole.
