FIG. 1 is a schematic diagram of an electronic atomization device provided in an embodiment of the present application.

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 removable. The device 10 is detachably connected to the power supply assembly 20, such as by interference fit, snap connection or magnetic connection.

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. 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.

FIG. 2 to FIG. 13 show a schematic diagram of the structure of an atomizer according to an embodiment; in the atomizer 10 of this embodiment, it includes:

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 a user or a smoker can inhale the aerosol generated by the electronic atomization device 100 through the mouthpiece 101a.

An aerosol output tube 101c and a liquid storage chamber 101d are provided in the housing 101. The upper end of the aerosol output tube 101c is communicated with the mouthpiece 101a, and the space between the outer surface of the aerosol output tube 101c and the inner surface of the housing 101 defines a liquid storage chamber 101d, that is, the liquid storage chamber 101d is arranged around at least part of the aerosol output tube 101c. The liquid storage chamber 101d is used to store a liquid matrix, and the liquid storage chamber 101d is communicated with the opening 101b. The atomizer assembly 102, the connecting tube 103, the bracket 104 and the sealing member 105 can be assembled to the housing 101 through the opening 101b.

In some examples, the inner surface of the housing 101 may be further provided with positioning posts (not shown), and when the sealing member 105 is assembled into the housing 101 through the opening 101 b , the sealing member 105 can be positioned by the positioning posts.

In some examples, at least a portion of the housing 101 is made of a transparent material, such as transparent plastic, so that the internal components and/or the liquid medium are visible through the housing 101 .

As shown in FIG6 , the atomization assembly 102 includes a liquid-conducting element 102a and a heating element 102b. The liquid-conducting element 102a is configured as a tubular structure along the length direction (the X direction shown in FIG2 ) of the atomizer 10 or the housing 101. The liquid-conducting element 102a can be made of a flexible fiber material, such as cotton fiber, non-woven fabric or sponge. Alternatively, in other examples, the liquid-conducting element 102a can also be a rigid porous body, such as porous ceramics, porous glass, etc.

The heating element 102b is disposed close to the inner surface of the liquid-conducting element 102a and can be attached to the liquid-conducting element 102a. The heating element 102b is provided on the inner surface of the liquid element 102a, or partially or completely embedded in the heating element 102b. The heating element 102b may be a resistance heating mesh, a resistance heating coil, etc. In a specific implementation, the heating element 102b may be formed by winding a sheet or mesh substrate, and the wound heating element 102b is a non-closed tubular structure in the circumferential direction, that is, a tubular structure with a side opening extending along the length direction of the atomizer 10. Conductive pins 102c and conductive pins 102d are welded or arranged at both ends of the heating element 102b to guide current on the heating element 102b.

As shown in FIG4 , the connecting tube 103 is connected to the aerosol output tube 101c and the bracket 104, respectively. The upper end of the connecting tube 103 is sleeved on the aerosol output tube 101c so that the lower end of the aerosol output tube 101c extends into the connecting tube 103; the lower end of the connecting tube 103 is plugged into or accommodated in the bracket 104. The connecting tube 103 is preferably made of a thinner rigid material, such as stainless steel. The connecting tube 103 and the bracket 104 are connected by interference fit, tight fit or interference fit, and a seal is formed between them while being tightly connected. In other examples, the connecting tube 103 and the aerosol output tube 101c can be formed integrally; that is, the upper end of the aerosol tube after being formed integrally is connected to the nozzle opening 101a, and the lower end is connected to the bracket 104.

The atomizer assembly 102 is disposed in the connecting tube 103, the atomizer assembly 102 and the connecting tube 103 are coaxially disposed, and the atomizer assembly 102 and the lower end of the aerosol output tube 101c are spaced apart. As shown in Figs. 7 and 8, the side wall of the connecting tube 103 is also provided with a liquid guide port 103a disposed near the lower end of the connecting tube 103, and the liquid guide port 103a is also accommodated in the bracket 104. The liquid matrix in the liquid storage chamber 101d can flow into the atomizer assembly 102 through the liquid guide port 103a, that is, it is sucked by the liquid guide element 102a, and atomized by the heating element 102b to generate an inhalable aerosol.

A notch groove 103 b is further provided on the side wall of the connecting tube 103 . The notch groove 103 b is also received in the bracket 104 . The notch groove 103 b extends from the lower end of the connecting tube 103 toward the upper end of the connecting tube 103 .

In one example, as shown in Figures 7 and 11, the extension length of the notch groove 103b is relatively long. In this way, on the one hand, a portion of the liquid-conducting element 102a can be exposed, which is conducive to the liquid-conducting element 102a absorbing the liquid matrix, and on the other hand, it can cooperate with the stopper 104j of the bracket 104, which is conducive to the assembly of the connecting tube 103 into the bracket 104. The outer surface of the liquid-conducting element 102a has a radially outward protrusion 102a1, which extends into the notch groove 103b after assembly to better absorb the liquid matrix.

In other examples, as shown in FIG8 , the extension length of the notch 103 b is shorter. The liquid matrix is mainly transferred to the liquid conducting element 102 a through the liquid conducting port 103 a on the side wall of the connecting tube 103 , and the notch 103 b is mainly used to cooperate with the stopper 104 j of the bracket 104 , so as to facilitate the assembly of the connecting tube 103 into the bracket 104 .

As shown in FIG4 , the bracket 104 is disposed near the liquid storage chamber 101 d and is made of a hard material, such as plastic. The bracket 104 includes a connecting portion 104 a and a supporting portion 104 b arranged along the length direction of the atomizer 10 .

As shown in Fig. 9-Fig. 12, the interior of the connecting portion 104a is defined with a chamber 104a1, and the upper end of the connecting portion 104a near the liquid storage chamber 101d has an opening connected to the chamber 104a1. The lower ends of the atomizing assembly 102 and the connecting pipe 103 extend into the chamber 104a1 from the opening at the upper end of the connecting portion 104a, and the liquid guide port 103a of the connecting pipe 103 is located in the chamber 104a1. A gap providing a liquid flow path is defined between the inner surface of the connecting portion 104a and the local outer surface of the connecting pipe 103, and the liquid guide port 103a is connected to the gap, so that the liquid matrix in the liquid storage chamber 101d flows to the atomizing assembly 102 through the gap. The flow path of the liquid matrix can be shown in R1 of Fig. 4.

In a further implementation, the gap includes a liquid inlet groove 104a2 disposed on the inner surface of the connecting portion 104a and close to the liquid guide port 103a, and the liquid inlet groove 104a2 extends toward the upper end of the connecting portion 104a. The liquid inlet groove 104a2 can increase the gap between the inner surface of the connecting portion 104a and the outer surface of the connecting tube 103 on the one hand, and facilitate the liquid matrix to flow to the liquid guide port 103a through the liquid inlet groove 104a2 on the other hand.

In further implementation, part of the inner surface near the upper end of the connecting portion 104a is inclined to the outer surface of the connecting tube 103, thereby forming an inclined portion 104a3. The inclined portion 104a3 can, on the one hand, increase the gap between the inner surface of the connecting portion 104a and the outer surface of the connecting tube 103, which is conducive to guiding the liquid matrix into the connecting tube 103; on the other hand, when the liquid matrix in the liquid storage chamber is nearly exhausted, the inclined portion 104a3 can guide the remaining liquid into the connecting tube 103, thereby improving the utilization rate of the liquid matrix.

In a further embodiment, as shown in FIG. 5 and FIG. 7 , the extension length d1 of the notch groove 103b from the lower end of the connecting tube 103 toward the upper end of the connecting tube 103 is greater than the minimum distance d2 between the lower end of the connecting tube 103 and the inclined portion 104a3. In this way, the portion of the liquid-conducting element 102a located in the connecting tube 103 is closer to or exposed to or extends to the inclined portion 104a3, thereby facilitating the absorption of the inclined portion 104a3. The inclined portion 104a3 guides the liquid matrix downward. Generally, the difference between d1 and d2 is between 0.2-1.5 mm, such as 0.5 mm, 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, etc.

As shown in Figures 11 and 12, the support portion 104b is at least partially disposed in the chamber 104a1. The connecting portion 104a also includes a bottom wall 104c extending from the inner surface of the connecting portion 104a along the width direction of the atomizer 10 (the Y direction shown in Figure 2) to the outer surface of the supporting portion 104b. During assembly, the lower end of the connecting tube 103 extends into the chamber 104a1 from the opening at the upper end of the connecting portion 104a, and the lower end of the connecting tube 103 is clamped between the inner surface of the connecting portion 104a and the outer surface of the supporting portion 104b and abuts against the bottom wall 104c. The atomizing assembly 102 abuts against the upper end of the supporting portion 104b, thereby being supported by the supporting portion 104b.

The inner surface of the portion near the lower end of the connecting portion 104a is closely attached to the outer surface of the connecting tube 103; this can reduce or prevent the liquid matrix from flowing to the bottom wall 104c. The groove defined by the inner surface of the connecting portion 104a, the outer surface of the supporting portion 104b, and the bottom wall 104c can also collect the leaked liquid matrix or the condensed liquid matrix, reducing the risk of the liquid matrix leaking to the outside of the atomizer 10 or the power supply assembly 20.

In a further implementation, a stopper 104j is further provided in the chamber 104a1 or on the bottom wall 104c to cooperate with the notch groove 103b. During assembly, the stopper 104j is used to provide installation guidance for the connecting tube 103, so that the liquid guide port 103a is aligned with the liquid inlet groove 104a2; specifically, the notch groove 103b is aligned with the stopper 104j, so that the connecting tube 103 is plugged into the connecting portion 104a. After being assembled in place, the liquid inlet groove 104a2 is aligned with the liquid guide port 103a, and the stopper 104j can limit the circumferential movement of the connecting tube 103.

As shown in FIG9 , the support 104 further includes an air inlet pipe 104d extending along the length direction of the atomizer 10. The air inlet pipe 104d is arranged outside the connecting portion 104a, and the air inlet pipe 104d is arranged close to the connecting portion 104a. The air inlet end of the air inlet pipe 104d is located on the end surface of the bottom end of the support 104, and the air outlet end of the air inlet pipe 104d is approximately located in the middle part of the support 104, and the air outlet end of the air inlet pipe 104d is arranged close to one side of the support 104 along the width direction of the atomizer 10.

The side wall of the support portion 104b has an air inlet hole 104b1, and the air inlet end of the air inlet hole 104b1 is offset from the air outlet end of the air inlet pipe 104d. The air inlet end of the air inlet hole 104b1 is arranged close to the side of the support 104 along the thickness direction (Z direction shown in FIG. 2) of the atomizer 10. In this way, the external air flows in through the air inlet end of the air inlet pipe 104d and flows out from the air outlet end of the air inlet pipe 104d. The air flows between the bracket 104 and the seal 105, along the gap between the bracket 104 and the seal 105, through the air inlet 104b1 into the hollow part in the support portion 104b, and then flows to the atomizer assembly 102 disposed in the connecting tube 103, and after mixing with the aerosol generated by the atomizer assembly 102, it is delivered to the mouthpiece 101a through the aerosol output tube 101c. The specific airflow path can be referred to as shown in R2 in Figures 5 and 9.

The support 104 further includes an electrode hole 104e and an electrode hole 104f extending along the length direction of the atomizer 10, the openings of the electrode hole 104e and the electrode hole 104f are located on the end surface of the bottom end of the support 104, and the electrode hole 104e and the electrode hole 104f are arranged at intervals. The electrode 107 is arranged in the electrode hole 104e, and the electrode 108 is arranged in the electrode hole 104f, and the electrode 107 and the electrode 108 are used to be electrically connected to the battery cell 21.

As shown in FIG11 , the support portion 104b has a wire hole 104b2 communicating with the electrode hole 104e, and a wire hole 104b3 communicating with the electrode hole 104f; the wire hole 104b2 and the wire hole 104b3 are arranged at intervals. In conjunction with FIG6 , it can be seen that the conductive pin 102c connected to the heating element 102b can maintain contact with the electrode 107 through the wire hole 104b2, thereby forming an electrical connection; the conductive pin 102d connected to the heating element 102b can maintain contact with the electrode 108 through the wire hole 104b3, thereby forming an electrical connection.

As shown in Fig. 10, the bracket 104 further includes a receiving portion 104g. The receiving portion 104g is formed by a depression of a portion of the end surface of the top end of the bracket 104. The receiving portion 104g is arranged close to one side of the bracket 104 along the width direction of the atomizer 10. In the example in Fig. 10, two receiving portions 104g are respectively arranged on the left and right sides of the connecting portion 104a.

As shown in FIG9 , a fin 104h is further provided between the receiving portion 104g and the air inlet pipe 104d. The fin 104h is spaced apart from the receiving portion 104g. The fin 104h extends outward from the outer surface of the connecting portion 104a along the width direction of the atomizer 10. The number of the fins 104h can be multiple, and the multiple fins 104h are spaced apart. The liquid matrix or the condensed liquid matrix can be hidden in the gap between two adjacent fins 104h or in the gap between the fin 104h and the receiving portion 104g.

As shown in Fig. 10, the bracket 104 further includes a flange 104i disposed near the bottom end of the bracket 104. The flange 104i extends outward from the outer surface of the bracket 104 along the width direction of the atomizer 10. During assembly, the distal end of the housing 101 abuts against the flange 104i.

As shown in Figures 13 and 14, the seal 105 is made of a flexible material. The seal 105 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 sealing member 105 includes a first portion 105 a extending along the width direction of the atomizer 10 , and a second portion 105 b extending from the first portion 105 a toward the bottom of the atomizer 10 .

The first part 105a has a through hole 105a1, and the inner surface of the first part 105a has a protrusion 105a2 extending toward the bottom of the atomizer 10. During assembly, the upper end of the connecting part 104a extends into the through hole 105a1, thereby sealing a portion of the outer surface of the connecting part 104a; the protrusion 105a2 is received in the receiving part 104g, thereby covering a portion of the end surface of the top end of the bracket 104 and sealing it.

The second part 105b is generally tubular in structure. During assembly, the second part 105b is sandwiched between the inner surface of the housing 101 and the outer surface of the bracket 104, and the second part 105b surrounds or covers the outer surface of the bracket 104. In this way, while forming a seal, the gas flowing out of the outlet end of the air inlet pipe 104d flows into the air inlet hole 104b1 along the gap between the bracket 104 and the sealing member 105.

In a further implementation, the outer surface of the second portion 105b further has flanges 105b1 and 105b2 that are spaced apart, and the flanges 105b1 and 105b2 abut against the inner surface of the housing 101, thereby forming a good sealing effect.

In a further implementation, an air pressure balance channel is further provided between the seal 105 and the bracket 104 for replenishing air into the liquid storage chamber 101d to relieve the negative pressure in the liquid storage chamber 101d.

Please refer to Figures 10-11 again, the bracket 104 also has an airflow groove 104g1. One end of the airflow groove 104g1 penetrates the bottom wall of the receiving portion 104g, and the other end of the airflow groove 104g1 extends from the inner surface of the receiving portion 104g, and then extends to the end surface of the upper end of the connecting portion 104a through the outer surface of the connecting portion 104a. In this way, after assembly, the protrusion 105a2 covers the airflow groove 104g1 to form an air pressure balance channel, and external air can flow in from one end of the airflow groove 104g1 and flow out from the other end of the airflow groove 104g1 to enter the liquid storage chamber 101d to relieve the negative pressure in the liquid storage chamber 101d.

As shown in FIG. 3 , the bottom cover 106 is detachably coupled to the housing 101 to define a The housing of the atomizer 10. In a preferred embodiment, the bottom cover 106 is snap-connected to the housing 101. The bottom cover 106 has a through hole 106a to expose the electrodes 107, 108 and the air inlet end of the air inlet pipe 104d.
