Of course, in other embodiments, the first body portion 9a11 can also be embedded or inserted in the battery accommodating housing 2a, so that the first body portion 9a11 can also be fixed to the battery accommodating housing 2a.

[0051]Similarly, the second connecting member 9a2 includes a second body portion 9a21, a second bent portion 9a22 bent inwardly and backwardly from one end (e.g., a bottom end) of the second body portion 9a21, and a fourth bent portion 9a23 bent inwardly and backwardly from another end (e.g., a top end) of the second body portion 9a21. The second bent portion 9a22 and the fourth bent portion 9a23 are closer to the second circuit board 8a1, so that the reliability of contact is high and the structure is relatively compact. The second bent portion 9a22 and the fourth bent portion 9a23 are both parallel to the second body portion 9a21. The second body portion 9a21 is insert-molded in the battery accommodating housing 2a. Both the second bent portion 9a22 and the fourth bent portion 9a23 are exposed in the accommodating space 2a3. Of course, in other embodiments, the second body portion 9a21 can also be embedded or inserted in the battery accommodating housing 2a, so that the second body portion 9a21 can also be fixed to the battery accommodating housing 2a.

[0052]Referring to FIGS. 7 to 12, FIG. 23 and FIG. 24, after the first circuit board 4a1 and the second circuit board 8a1 are assembled in place, the first bent portion 9a12 is in abutment with the first contact element 4a11, the third bent portion 9a13 is in abutment with the third contact element 8a11, the second bent portion 9a22 is in abutment with the second contact element 4a12, and the fourth bent portion 9a23 is in abutment with the fourth contact element 8a12.

The e-liquid tank lower sealing cover 8b is at least partially inserted into the e-liquid tank housing 4b, and is sealed at a lower end of the e-liquid tank housing 4b. It should be noted that it is understandable to those skilled in the art that the terminology “seal” used herein refers to preventing the e-liquid from leaking to other places than an e-liquid channel.

[0060]The e-liquid storage element 5b is adapted for storing e-liquid. In an embodiment of the present disclosure, the e-liquid storage element 5b is an e-liquid storage cotton. The e-liquid storage element 5b is received in the e-liquid tank housing 4b. The e-liquid storage element 5b defines a second channel 5b1 communicating with the first channel 3b1 of the e-liquid tank upper sealing cover 3b.

[0061]The e-liquid guiding element 6b is in contact with the e-liquid storage element 5b, so as to guide and absorb the e-liquid derived from the e-liquid storage element 5b. In an embodiment of the present disclosure, the e-liquid guiding element 6b is an e-liquid guiding cotton. The e-liquid guiding element 6b includes a pipe body 6b1, a first extension portion 6b2 extending from one side of the pipe body 6b1, and a second extension portion 6b3 extending from another side of the pipe body 6b1. The pipe body 6b1 is provided with a third channel 6b11 communicating with the second channel 5b1. The first extension portion 6b2 and the second extension portion 6b3 are substantially flat.

[0062]In an embodiment of the present disclosure, the clamping pipe 7b is a hollow metal pipe. The clamping pipe 7b is provided with an accommodation space 7b1. The clamping pipe 7b is of a substantially cylindrical shape. The pipe body 6b1 of the e-liquid guiding element 6b is received in the accommodation space 7b1. The clamping pipe 7b includes slots 7b2 extending in the axial direction and extending backwardly through an outer wall of the clamping pipe 7b. The first extension portion 6b2 and the second extension portion 6b3 of the e-liquid guiding element 6b are inserted into the slots 7b2 so as to be assembled with the clamping pipe 7b.

[0063]In an embodiment of the present disclosure, the e-liquid tank lower sealing cover 8b is a soft rubber sealing cover in order to improve the sealing performance. Preferably, the e-liquid tank lower sealing cover 8b is inserted into the e-liquid tank housing 4b by means of elastic extrusion. In this way, on the premise of not affecting the fixing effect, the e-liquid can be prevented from leaking to the outside as much as possible, and the convenience of assembly and disassembly is also improved.

[0064]In an embodiment of the present disclosure, the heating element 9b is a heating wire. The heating element 9b includes a heating portion 9b1, a first connecting wire 9b2 connected to the heating portion 9b1, and a second connecting wire 9b3 connected to the heating portion 9b1. The heating portion 9b1 is received in the accommodation space 7b1 of the clamping pipe 7b and/or the pipe body 6b1 of the e-liquid guiding element 6b. The first connecting wire 9b2 and the second connecting wire 9b3 pass through the e-liquid tank lower sealing cover 8b to extend beyond the e-liquid tank lower sealing cover 8b.

[0065]In an embodiment of the present disclosure, the sealing cover assembly 10b includes a sealing cover 10b1, a first contact terminal 10b2 fixed to the sealing cover 10b1, and a second contact terminal 10b3 fixed to the sealing cover 10b1. In the embodiment shown in the present disclosure, the first contact terminal 10b2 and the second contact terminal 10b3 are assembled and fixed in the sealing cover 10b1. In the embodiment shown in the present disclosure, the sealing cover 1b1 includes a first terminal mounting hole 10b11, a second terminal mounting hole 10b12, and a positioning post 10b13 located between the first terminal mounting hole 10b11 and the second terminal mounting hole 10b12. The first contact terminal 10b2 and the second contact terminal 10b3 are inserted into the first terminal mounting hole 10b11 and the second terminal mounting hole 10b12, respectively. The e-liquid tank lower sealing cover 8b is sleeved on the positioning post 10b13, so as to improve the assembly precision.

[0066]In the embodiment shown in the present disclosure, the first contact terminal 10b2 and the second contact terminal 10b3 are both of hollow configurations. The first contact terminal 10b2 includes a first receiving portion 10b21 and a first slit 10b22 for holding the first connecting wire 9b2. The first receiving portion 10b21 has elasticity so as to better accommodate the first plug portion 8a21 of the first mating terminal 8a2. In the embodiment shown in the present disclosure, the first receiving portion 10b21 is provided with a plurality of slots extending along the axial direction. The slots extend through the first receiving portion 10b21 in a direction away from the heating element 9b, so that the first receiving portion 10b21 has a certain elasticity.

[0067]Similarly, the second contact terminal 10b3 includes a second receiving portion 10b31 and a second slit 10b32 for holding the second connecting wire 9b3. The second receiving portion 10b31 has elasticity, so as to better receive the second plug portion 8a31 of the second mating terminal 8a3. In the embodiment shown in the present disclosure, the second receiving portion 10b31 is provided with a plurality of slots extending along the axial direction. The slots extend through the second accommodating portion 10b31 in a direction away from the heating element 9b, so that the second accommodating portion 10b31 has a certain elasticity. In this way, when the electronic atomization heating battery assembly 100 and the electronic atomization heating e-liquid storage assembly 200 are disassembled and then assembled, the first mating terminal 8a2 and the second mating terminal 8a3 can be reliably contacted with the first contact terminal 10b2 and the second contact terminal 10b3, respectively, thereby ensuring proper electrical function.

[0068]In an embodiment of the present disclosure, when the electronic atomization heating e-liquid storage assembly 200 is assembled, the first contact terminal 10b2 and the second contact terminal 10b3 are fixed to the sealing cover 10b1 to form the sealing cover assembly 10b. The first connecting wire 9b2 and the second connecting wire 9b3 of the heating element 9b are clipped into the corresponding first slit 10b22 and the second slit 10b32. The aforementioned assembly is assembled with the e-liquid tank lower sealing cover 8b, so that the heating portion 9b1 passes through the e-liquid tank lower sealing cover 8b. The clamping pipe 7b is sleeved on the heating portion 9b1. The e-liquid guiding element 6b is inserted into the slot 7b2 of the clamping pipe 7b. The aforementioned assembly is assembled with the e-liquid storage element 5b. The aforementioned assembly is integrally assembled into the e-liquid tank housing 4b. The e-liquid tank upper sealing cover 3b is assembled into the e-liquid tank housing 4b. The e-liquid absorbing element 2b is assembled to the e-liquid tank upper sealing cover 3b. Finally, the aforementioned assembly is assembled into the second receiving space 1b2 of the second housing 1b.

[0069]When the electronic atomization heating device 300 is in a charging state, the electrical connector 4a2 is connected to a mating connector. The battery 3a can be charged under the control of the first circuit board 4a1.

[0070]Referring to FIGS. 25 and 26, when the electronic atomization heating device 300 is in use, the battery 3a is connected through the first circuit board 4a1, the first connecting member 9a1, the second connecting member 9a2, the second circuit board 8a1, the first mating terminal 8a2, the second mating terminal 8a3, the first contact terminal 10b2, the second contact terminal 10b3, the first connecting wire 9b2 and the second connecting wire 9b3 so as to provide power to the heating portion 9b1. At this time, the heating portion 9b1 generates heat and heats the e-liquid. The heated e-liquid is in a gaseous state, and passes through the third channel 6b11, the second channel 5b1, the first channel 3b1 and the perforation 2b1 to reach the mouthpiece 1b1. The e-liquid storage element 5b is capable of storing (e.g., absorbing) e-liquid. The e-liquid guiding element 6b is in contact with the e-liquid storage element 5b, so that the e-liquid in the e-liquid storage element 5b is gradually transferred to the e-liquid guiding element 6b, and the e-liquid is heated by the heating portion 9b1. With this arrangement, the e-liquid can be fully heated to be in a gaseous state, which avoids heating all the e-liquid at the same time, thereby improving the heating efficiency.

[0071]Compared with the prior art, many components of the present disclosure are assembled in a detachable manner, so these components can be reused, which saves costs and reduces pollution. In addition, these components are assembled along the axial direction, so that automatic assembly can be realized more easily, production efficiency can be improved, and installation errors can be reduced.
