[0099] Figure 1 is a schematic assembly diagram of the electronic cigarette provided by the embodiment of the present invention, Figure 2 is a schematic disassembly diagram of the electronic cigarette provided by the embodiment of the present invention, Figure 3 is a schematic cross-sectional view of the electronic cigarette provided by the embodiment of the present invention. As Figures 1-3 shown, the electronic cigarette in this embodiment includes an electronic cigarette rod B and an atomizer A detachably mounted on the electronic cigarette rod B. It is easy to understand that the atomizer A is a storage body for e-liquid. When the electronic cigarette works, the electronic cigarette rod B provides electrical energy for the atomizer A, so that the e-liquid in the atomizer A can be heated and atomized, and thus can be inhaled by the user.

[0100] Figure 4 is a schematic structural diagram of the electronic cigarette rod B provided by the embodiment of the present invention, Figure 5 is a schematic cross-sectional view of the electronic cigarette rod B provided by the embodiment of the present invention, Figure 6 is an exploded schematic diagram of the electronic cigarette rod B provided by the embodiment of the present invention. As Figures 4-6 shown, the electronic cigarette rod B includes a battery box 1, a bottom cover 2, and a charging connection module 3. Among them, in combination with Figures 7-8As shown, a first accommodation cavity a is formed inside the battery box 1. It is easy to understand that the first accommodation cavity a is used to place the battery that provides electrical energy for the atomizer A. At the same time, an air outlet 11 communicating with the first accommodation cavity a is provided at the first end of the battery box 1, and a first through hole 12 communicating with the first accommodation cavity a is provided at the second end of the battery box 1. Thus, after the air enters the first accommodation cavity a from the first through hole 12, it can be discharged through the air outlet 11. As an alternative implementation, the battery box 1 is made of polycarbonate (abbreviation: PC) or polybutylene terephthalate (abbreviation: PBT).

[0101] Furthermore, the bottom cover 2 includes a bottom plate 21 and a side wall 22 extending from the edge of the bottom plate 21 towards the battery box 1. The bottom cover 2 is used to cover one end of the battery box 1 through the formed opening. Specifically, the bottom cover 2 is connected to the second end of the battery box 1 through the side wall 22 to cooperate with the battery box 1 to form a second accommodation cavity b. It should be noted that an air inlet 23 is provided on the bottom plate 21, that is, the air inlet 23 communicates with the second accommodation cavity b. Thus, after the air enters the second accommodation cavity b from the air inlet 23, it can enter the first accommodation cavity a through the first through hole 12 at the second end of the battery box 1 and then be discharged through the air outlet 11 at the first end of the battery box 1. As an alternative implementation, the bottom cover 2 is made of polycarbonate (abbreviation: PC) or polybutylene terephthalate (abbreviation: PBT).

[0102] Combined with Figures 9-10 As shown, in one implementation, a buckle hole 24 is provided on the side wall 22 of the bottom cover 2. Further, a third buckle 19 matching the buckle hole 24 is provided at the second end of the battery box 1, and the third buckle 19 fixes the bottom cover 2 through the buckle hole 24. It should be noted that using the buckling method to fix the bottom cover 2 is not only convenient for maintenance and replacement, but also can simplify the installation steps, which is beneficial to realizing assembly automation.

[0103] It should be noted that the first end of the battery box 1 is used to dock with the atomizer A, and the atomizer A has a through channel so that air can flow inside the atomizer A. Thus, when the electronic cigarette rod B is docked with the atomizer A, the air inlet 23, the second accommodation cavity b, the first through hole 12, the first accommodation cavity a, and the air outlet 11 form an air flow channel communicating with the atomizer A, that is, the electronic cigarette inhales air through the air inlet 23 on the electronic cigarette rod B.

[0104] Even further, Figure 11 is a schematic structural diagram of the charging connection module 3 provided by the embodiment of the present invention. Combined with Figure 11As shown, the charging connection module 3 is disposed in the second accommodation cavity b. It should be noted that the output terminal 31 of the charging connection module 3 extends into the first accommodation cavity a through the first through hole 12 to connect to the battery 4 placed in the first accommodation cavity a for charging. At the same time, the input terminal 32 of the charging connection module 3 is configured to be connected to an external power source through the air inlet 23. It should be further noted that a certain distance is provided between the outer peripheral side of the input terminal 32 and the inner side wall of the air inlet 23, and the distance is used to communicate with the external air. That is to say, the external power source can be inserted into the air inlet 23 and connected to the input terminal 32 of the charging connection module 3 to charge the battery 4 in the first accommodation cavity a. Thus, the electronic cigarette rod B in this embodiment realizes the use of the air inlet 23 for both ventilation and charging, so that the electronic cigarette rod B does not need to be provided with holes for different purposes respectively, which not only makes full use of the charging structure of the electronic cigarette rod B, but also can improve the production efficiency and reduce the production cost by simplifying the structure.

[0105] In one embodiment, the bottom plate 21 extends from the edge of the air inlet 23 towards the battery box 1 to form an air inlet channel 231, and the input terminal 32 is located in the air inlet channel 231. It should be noted that the input terminal 32 is configured to conform to a predetermined charging protocol, and the air inlet channel 231 is formed into a charging interface that matches the predetermined charging protocol. It should be further noted that the predetermined charging protocol includes but is not limited to the PD fast charging protocol, the QC fast charging protocol, etc. As an optional embodiment, the input terminal 32 conforms to the PD fast charging protocol, and the air inlet channel 231 is formed into a Type-C interface that matches the PD fast charging protocol.

[0106] Figure 12 is a schematic structural diagram of the battery 4 provided by the embodiment of the present invention, in combination with Figure 12 As shown, in one embodiment, the electronic cigarette rod B further includes a battery 4. Among them, the battery 4 includes but is not limited to rechargeable batteries such as lithium batteries and nickel-chromium batteries, and the battery 4 is disposed in the first accommodation cavity a. It should be noted that the size of the first accommodation cavity a is relatively large to ensure that there is enough space for air flow after the battery 4 is placed, so that the air inhaled from the air inlet 23 can be discharged from the air outlet 11. Further, the output terminal 31 of the charging connection module 3 is connected to the battery 4 through the first through hole 12. It should be noted that the shape of the first through hole 12 matches the output terminal 31, and at the same time, the size of the first through hole 12 is slightly larger than the output terminal 31. As an optional embodiment, the first through hole 12 can be recessed outward from the edge to increase the size of the first through hole 12 to facilitate air flow.

[0107] In one embodiment, one end of the battery 4 facing the bottom cover 2 has an extended tab 41 for leading the positive and negative electrodes out from the battery cell of the battery 4 to a specific position. Specifically, the tab 41 is provided as a metal conductor, and an electrode plate is provided on the tab 41. In this embodiment, the tab 41 is disposed opposite to the first through hole 12, and the output terminal 31 of the charging connection module 3 is connected to the electrode plate through the first through hole 12, so that the input terminal 32 can charge the battery 4 after being connected to an external power supply.

[0108] In one embodiment, the first through hole 12 extends from the edge towards the first end of the battery case 1 to form a support portion 121, and the size of the support portion 121 matches that of the output terminal 31. In this embodiment, the output terminal 31 and the tab 41 are stacked on the support portion 121. Specifically, when the output terminal 31 extends into the first receiving cavity a from the first through hole 12, it is located on the support portion 121, and then the battery 4 is placed into the first receiving cavity a, so that the tab 41 can be placed on the output terminal 31. It should be noted that the side of the tab 41 with the electrode plate faces the output terminal 31, so that the output terminal 31 can connect to the electrode plate.

[0109] Combined Figures 13-16 As shown, in one embodiment, the battery case 1 includes a battery case body 13 and a battery cover 14. Among them, the side surface of the battery case body 13 has an opening, and the battery cover 14 matches the opening. Further, a pressing portion 141 is provided on the side of the battery cover 14 facing the battery 4. In this embodiment, the battery cover 14 is configured to close the first receiving cavity a and press the tab 41 and the output terminal 31 located on the support portion 121 through the pressing portion 141. That is to say, when the battery cover 14 closes the opening on the side surface of the battery case body 13, the pressing portion 141 presses the tab 41 of the battery 4, so as to ensure that the tab 41 can be in contact with the output terminal 31 under the cooperation of the support portion 121, avoiding poor contact.

[0110] In one embodiment, a buckle 131 is provided on the battery case body 13, and a first buckle 142 matching the buckle 131 is provided on the battery cover 14. In this embodiment, the battery cover 14 is fixedly connected to the battery case body 13 through the first buckle 142 and the buckle 131. Thus, the battery case body 13 and the battery cover 14 are fixed by a snap connection method, which is not only convenient for subsequent maintenance work, but also can simplify the production and assembly process, contributing to the realization of automation. It is easy to understand that a buckle can also be provided on the battery cover 14 and a corresponding buckle can be provided on the battery case body 13.

[0111] Combined Figure 17As shown, as an alternative embodiment, the battery cover 14 includes a cover body 14a and a pressing member 14b. Among them, the cover body 14a matches the opening on the side of the battery box body 13 and is used to close the first accommodation cavity a. A pressing portion 14c is formed on the side of the pressing member 14b facing the battery 4 so as to press the ear 41 and the output terminal 31 on the pressing support portion 121. In this embodiment, after the battery 4 is placed in the first accommodation cavity a, first align the pressing member 14b with the ear 41 and then use the cover body 14a to close the opening on the side of the battery box body 13, and at the same time press the pressing member 14b to indirectly press the ear 41 and the output terminal 31 to ensure the reliability of their contact. By using the method of pressing with the pressing member 14b, it is beneficial to determine the structure of the pressing member 14b according to actual needs without additionally designing and manufacturing the cover body 14a, and it is also beneficial to repair and replace the pressing member 14b.

[0112] Combined with Figure 18 As shown, in one embodiment, the e-cigarette rod B further includes a power supply terminal 5 and an electrical connector 6. Among them, the power supply terminal 5 extends out of the first end of the battery box 1, and both ends of the electrical connector 6 are respectively connected to the power supply terminal 5 and the charging connection module 3. In this embodiment, the power supply terminal 5 is made of pure copper, phosphor bronze or other conductive materials and is used to provide the electric energy stored in the battery 4 to the atomizer A. Thus, the e-cigarette rod B can be connected to an external power supply through the air inlet 23 to charge the battery 4; when the user uses the e-cigarette, the e-cigarette rod B provides electric energy through the power supply terminal 5 docked with the terminals of the atomizer A, so that the e-liquid stored in the atomizer A can be atomized for the user to inhale.

[0113] In one embodiment, the electrical connector 6 is provided as a metal sheet made of pure copper, phosphor bronze or other conductive materials. It is easy to understand that the metal sheet has good ductility and conductivity; at the same time, the sheet-like structure has high strength, which is convenient for inspection and replacement, and it is also convenient for the electrical connector 6 fixed with the power supply terminal 5 to be inserted into the first accommodation cavity a from the second end of the battery box 1 and push the power supply terminal 5 out of the first end of the battery box 1. In this embodiment, a slot 132 communicating with the second through hole 15 is provided on the inner wall of the battery box body 13, and the slot 132 matches the size of the metal sheet so that the metal sheet can be inserted into the first accommodation cavity a through the slot 132. It is easy to understand that the slot 132 plays a role of limiting and guiding the metal sheet. As an alternative embodiment, the electrical connector 6 can be provided as a wire made of copper or other conductive materials.

[0114] In one embodiment, a second through hole 15 is provided at the first end of the battery case 1, and the power supply terminal 5 extends out of the first end of the battery case 1 through the second through hole 15. Further, the second through hole 15 extends from the edge in a direction away from the bottom cover 2 to form a terminal channel 151. It should be noted that the terminal channel 151 can play a role in limiting and guiding the power supply terminal 5. In this embodiment, the air outlet 11 extends from the edge in a direction away from the bottom cover 2 to form an air outlet channel 111. Thus, the terminal channel 151 and the air outlet channel 111 form a protrusion relative to the first end of the battery case 1, which is beneficial to the docking of the electronic cigarette rod B and the atomizer A.

[0115] In one embodiment, a ring-shaped limiting portion 16 is formed by the first end of the battery case 1 protruding in a direction away from the bottom cover 2. Further, the limiting portion 16 is disposed around the periphery of the terminal channel 151 and the air outlet channel 111. It should be noted that by providing the protruding limiting portion 16, it helps the docking of the electronic cigarette rod B and the atomizer A. Combining Figure 19 As shown, in this embodiment, the electronic cigarette rod B further includes an oil-absorbing cotton 7. The oil-absorbing cotton 7 is made of a fibrous material with an adsorption function, and is used to prevent e-liquid from leaking from the atomizer A and entering the battery case 1 through adsorption. It should be noted that the oil-absorbing cotton 7 is disposed inside the limiting portion 16, and the oil-absorbing cotton 7 has an avoidance structure 71. It is easy to understand that the avoidance structure 71 includes an avoidance groove and / or an avoidance hole, and the terminal channel 151 and the air outlet channel 111 pass through the oil-absorbing cotton 7 through the avoidance structure 71. It should be noted that the protruding terminal channel 151 and air outlet channel 111 help to prevent e-liquid from entering the battery case 1 through the air outlet 11 and the second through hole 15.

[0116] Combining Figure 20 As shown, in one embodiment, the electronic cigarette rod B further includes a leak-proof plug 8. The leak-proof plug 8 is made of silica gel and is used to prevent e-liquid leakage. Among them, the leak-proof plug 8 is disposed at one end of the electrical connector 6 close to the bottom cover 2.
