[0040] Refer to Figures 1 to 4 , a connection structure for an electronic cigarette. The connection structure includes a main body 100 and a base 200 in the electronic cigarette. The base 200 is detachably connected to one end of the main body 100, and the base 200 is used for detachably installing a cartridge 400. The main body 100 has a first accommodation space 110 for accommodating the cartridge 400.

[0041] Specifically, the cartridge 400 is detachably disposed on the base 200. When the base 200 is connected to the main unit 100, the cartridge 400 can be located in the first accommodation space 110 in the main unit 100.

[0042] Furthermore, an assembly space 120 can also be provided in the main unit 100.

[0043] The connection structure includes a telescopic locking structure 300, and the telescopic locking structure 300 is disposed in the assembly space 120.

[0044] The base 200 is provided with a hook 210 that cooperates with the telescopic locking structure 300. When the base 200 is pressed during the connection process with the main unit 100, the telescopic locking structure 300 locks the hook 210 in the pressed position and unlocks it when pressed again.

[0045] That is to say, in the connection structure applied to the electronic cigarette of the present application, the hook 210 is provided on the base 200 of the electronic cigarette, and the telescopic locking structure 300 is provided in the main unit 100. Through the pressing cooperation between the hook 210 and the telescopic locking structure 300, the locking and unlocking of the hook 210 and the telescopic locking structure 300 can be realized. Furthermore, pressing the base 200 can fix the connection between the base 200 and the main unit 100, and then pressing again can lock the contact between the base 200 and the main unit 100. This method can facilitate the removal of the base 200 from the main unit 100 for replacing the cartridge 400, and this method makes the connection structure between the base 200 and the main unit 100 more durable.

[0046] Furthermore, referring to Figure 5 and Figure 7 , in some embodiments, the telescopic locking structure 300 is a door latch switch. The latch 310 of the door latch switch is movably engaged with the hook 210. When the base 200 is pressed, the latch 310 locks the hook 210 in the pressed position and unlocks it when pressed again.

[0047] It should be noted that the structure of the door latch switch itself is a prior art, and the specific structure of the door latch switch will not be described in detail here. This embodiment only utilizes the structure of the door latch switch

[0048] Combined with Figure 2 and Figure 7 , the main unit 100 may include a housing 130. A cavity is provided in the housing 130, and the cavity extends to one end of the housing 130 to form an opening. The cavity includes an assembly space 120, a first accommodation space 110, and a second accommodation space 140 for accommodating the base 200, and the second accommodation space 140 is close to the opening.

[0049] The base 200 is inserted into the second accommodation space 140 through the opening, and the hook 210 can be movably engaged with the telescopic locking structure 300.

[0050] Specifically, in some embodiments, the assembly space 120, the first accommodation space 110, and the second accommodation space 140 for accommodating the base 200 may be interconnected with each other.

[0051] After the base 200 is inserted into the second accommodation space 140 through the opening, the cartridge 400 located on the base 200 can be exactly located within the first accommodation space 110. The hook 210 on the base 200 can exactly cooperate and connect with the telescopic locking structure 300, such as the buckle 310 of the door latch switch. Then, by pressing the base 200, the telescopic locking structure 300 locks the hook 210, thereby fixing the base 200 within the second accommodation space 140 of the housing.

[0052] Optionally, the base 200 can be partially or completely accommodated within the second accommodation space 140.

[0053] Refer to Figure 3 、 Figure 4 and Figure 7 As shown in, the base 200 may include a bottom case 220 and a bottom cover 230 disposed on the bottom case 220. The interior of the bottom case 220 is used to mount the main board 900. A hook 210 and a cartridge mounting structure for mounting the cartridge 400 are respectively disposed on the bottom case 220.

[0054] Furthermore, for the convenience of detaching the cartridge 400 from the base 200, the cartridge mounting structure may include a threaded seat 240 and an electrode 250 disposed within the threaded seat 240. An insulating member 260 is disposed between the threaded seat 240 and the electrode 250. The threaded seat 240 and the electrode 250 are respectively connected to the main board 900. The threaded seat 240 is used for threaded connection with the cartridge 400, and the electrode 250 is used for contacting the cartridge 400. Thus, the threaded seat 240 and the electrode 250 form the positive and negative electrodes of the cartridge 400, realizing the control connection between the main board 900 and the cartridge 400.

[0055] Furthermore, in some embodiments, in order to ensure the sealing between the base 200 and the main unit 100 after the cartridge 400 is accommodated within the first accommodation space 110, so as to prevent the leakage of the cartridge 400, an annular step 150 may be provided at one end of the first accommodation space 110 close to the insertion of the cartridge 400. A sealing ring 270 is disposed on the base 200. When the base 200 is connected to the main unit 100, the sealing ring 270 abuts against the annular step 150, and the sealing ring 270 can undergo elastic deformation.

[0056] It is understandable that after the base 200 is connected to the main unit 100, the sealing ring 270 on the base 200 can exactly abut against the annular step 150, realizing the sealing of the position corresponding to the cartridge 400 at the connection between the base 200 and the main unit 100. Then, when the base 200 and the main unit 100 are unlocked, it is necessary to press the base 200 so that the telescopic locking structure 300 can release the locking of the hook 210 on the base 200. Therefore, when pressing the base 200, the sealing ring 270 undergoes elastic deformation to avoid blocking the pressing of the base 200.

[0057] For example, in some embodiments, the sealing ring 270 can be made of silicone.

[0058] Refer to Figure 3 , the hook 210 can include a protruding portion 211 provided on the base 200. On both sides of the end of the protruding portion 211 away from the base 200, there are respectively provided hook portions 212. The hook portions 212 cooperate with the telescopic locking structure 300 for clamping, so that the telescopic locking structure 300 can lock the hook 210.

[0059] Furthermore, in order to facilitate the movable cooperation between the hook portion 212 and the telescopic locking structure 300, such as the buckle 310 when it is a door latch switch, a guiding inclined surface 213 can also be provided on the end surface of the hook portion 212 away from the base 200.

[0060] In addition, refer to Figure 1 and Figure 7 , the present application also provides an electronic cigarette, including a cartridge 400 and the connection structure in the above embodiments. The cartridge 400 is detachably arranged on the base 200, and when the base 200 is connected to the main unit 100, the cartridge 400 is located in the first accommodation space 110.

[0061] Furthermore, the main unit 100 includes a housing 130. A cavity is provided inside the housing 130, and the cavity extends to one end of the housing 130 to form an opening. A bracket 160 is provided inside the cavity, and the bracket 160 divides the cavity into at least an assembly space 120, a first accommodation space 110, and a second accommodation space 140 for accommodating the base 200.

[0062] A battery 500 is also provided in the assembly space 120. The battery 500 is electrically connected to a cartridge pin 600. A contact 700 electrically connected to the cartridge 400 is provided on the base 200. When the base 200 is connected to the main unit 100, the cartridge pin 600 contacts the contact 700, and the cartridge pin 600 can expand and contract when subjected to a pressing force.

[0063] Specifically, when a main board 900 is provided inside the base 200, the contact 700 can be electrically connected to the main board 900.

[0064] In some embodiments, in order to save space of the host 100, the battery 500 may be disposed at one end of the telescopic locking structure 300 away from the base 200 in the assembly space 120.

[0065] Refer to Figure 1 and Figure 7 , in some embodiments, the electronic cigarette may further include a mouthpiece 800, the mouthpiece 800 is disposed at one end of the housing 130 away from the base 200, and the flue of the mouthpiece 800 is communicated with the first accommodating space 110.

[0066] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
