[0035] The electronic cigarette proposed in this application includes an atomizing device, an electronic control device, a locking component, and a resilient component. One end of the atomizing device has an internally connected slot and a locking groove. The slot's opening is located on the end face of the atomizing device, and the locking groove's opening faces the slot. The extension direction of the slot intersects the extension direction of the locking groove. One end of the electronic control device has an internally formed movable channel. One end of the movable channel's opening is located on the end face of the electronic control device, and the other end's opening is located on the side of the electronic control device. The locking component passes through the movable channel and includes a locking end, a middle section, and an operating end connected sequentially. The locking end extends beyond the end face of the electronic control device and is used to insert into the slot and the locking groove. The middle section is located within the movable channel, and the operating end is exposed on the side of the electronic control device. The resilient component is at least partially located within the movable channel, with its two ends connected to the wall of the movable channel and the operating end, respectively.

In the locked state, the locking end is locked by the wall of the lock groove with the cooperation of the elastic element and the movable through groove. In the unlocked state, the locking end is not locked by the wall of the lock groove.
[0036] In the electronic cigarette of this application, the connection between the locking component and the slot and groove can guide and limit the physical and electrical connection between the atomizing device and the electronic control device. When the locking component is in the locked state, the locking end is locked by the wall of the groove with the cooperation of the elastic element and the movable through groove, and no undesirable movement will occur between the atomizing device and the electronic control device, resulting in a better connection effect between the atomizing device and the electronic control device. When the locking component is in the unlocked state, the locking component can be removed by the user from the groove and slot, so that the atomizing device and the electronic control device can be detached from each other, and the atomizing device can be replaced.
[0037] The following will mainly describe the specific structure of electronic cigarettes.
[0038] Please see Figures 1 to 5 The electronic cigarette 100 of this application includes an atomizing device 110. The atomizing device 110 is capable of atomizing e-liquid into a vapor. An interconnected slot 111 and locking groove 112 are formed inside one end of the atomizing device 110. The opening of the slot 111 is formed on the end face of the atomizing device 110, and the opening of the locking groove 112 faces the slot 111. The extending direction of the slot 111 intersects the extending direction of the locking groove 112. The extending direction of the slot 111 and the extending direction of the locking groove 112 may be perpendicular or not. The flow cross-sectional area of the slot 111 is larger than the flow cross-sectional area of the locking groove 112.
[0039] Please see Figures 1 to 5Specifically, the atomizing device 110 may include an upper shell 113 and a base 114. The base 114 is fitted into the bottom end of the upper shell 113. A slot 111 and a locking groove 112 are formed within the base 114. The locking groove 112 is a through groove, with one end of the groove facing the slot 111, and the wall of the other end of the groove connecting to the inner wall of the upper shell 113. This facilitates the fabrication of the slot 111 and the locking groove 112. The upper shell 113 and the base 114 may be snap-fitted, glued, or screwed together.
[0040] Please see Figure 4 and Figure 5 The extension direction of slot 111 is parallel to the axis of atomizing device 110, and the extension direction of locking groove 112 is perpendicular to the axis of atomizing device 110. That is, the extension direction of slot 111 is perpendicular to the extension direction of locking groove 112. The above arrangement makes the fabrication of slot 111 and locking groove 112 relatively convenient.
[0041] Please see Figures 1 to 5 The electronic cigarette 100 of this application includes an electronic control device 120. The electronic control device 120 is physically and electrically connected to the atomizing device 110, and the electronic control device 120 can control the atomization of the atomizing device 110. The electronic control device 120 and the atomizing device 110 can be assembled and disassembled, thereby facilitating their transportation and replacement, and also preventing the e-liquid in the atomizing device 110 from leaking into the electronic control device 120.
[0042] Please see Figures 1 to 5 The inside of one end of the electronic control device 120 is formed with a movable through groove 121. One end of the movable through groove 121 is opened on the end face of the electronic control device 120, and the other end of the movable through groove 121 is opened on the side of the electronic control device 120.
[0043] Please see Figure 4 and Figure 5 Specifically, the movable channel 121 includes a first channel segment 122 and a second channel segment 123 that are interconnected. The extension direction of the first channel segment 122 is parallel to the axis of the electronic control device 120, and the extension direction of the second channel segment 123 is perpendicular to the axis of the electronic control device 120. The axis of the electronic control device 120 is parallel to the axis of the atomizing device 110, that is, the extension direction of the first channel segment 122 is parallel to the axis of the slot 111, and the extension direction of the second channel segment 123 is parallel to the axis of the locking slot 112.
[0044] Please see Figures 1 to 6The electronic cigarette 100 of this application includes a locking member 130, which passes through a movable channel 121. One end of the locking member 130 extends out of the movable channel 121 and is used to connect the slot 111 and the locking groove 112 of the atomizing device 110, thereby realizing the connection between the atomizing device 110 and the electronic control device 120. Specifically, the locking member 130 includes a locking end 131, a middle section 132, and an operating end 133 connected in sequence. The locking end 131 extends out of the end face of the electronic control device 120 and is used to insert into the slot 111 and the locking groove 112. The middle section 132 is located in the movable channel 121, and the operating end 133 is exposed on the side of the electronic control device 120. The locking member 130 is movable inside the slot 111, the locking groove 112, and the movable channel 121.
[0045] Please see Figures 3 to 5 The electronic cigarette 100 of this application includes an elastic element 140, which is at least partially located within a movable channel 121. Both ends of the elastic element 140 are connected to the wall of the movable channel 121 and the operating end 133, respectively. The elastic element 140 is in a compressed state. The elastic element 140 can limit the movement of the locking element 130. The cooperation of the locking element 130, the slot 111, the locking groove 112, the movable channel 121, and the elastic element 140 can guide and limit the assembly and disassembly of the atomizing device 110 and the electronic control device 120.
[0046] Please see Figure 4 The locking element 130 is in a locked state. At this time, the locking end 131 is locked by the wall of the locking groove 112 with the cooperation of the elastic element 140 and the movable through groove 121. As a result, no undesirable movement will occur between the atomizing device 110 and the electronic control device 120, and the connection effect between the atomizing device 110 and the electronic control device 120 is relatively good.
[0047] Please see Figure 5 The locking element 130 is in an unlocked state. At this time, the locking end 131 is not locked by the wall of the locking groove 112. The locking element 130 can be removed by the user from the locking groove 112 and the slot 111, so that the atomizing device 110 and the electronic control device 120 can be separated from each other, and the atomizing device 110 can be replaced.
[0048] Please see Figures 3 to 6 The locking end 131 is inverted L-shaped. Thus, the shape of the locking end 131 is adapted to the shape of the slot 111 and the locking groove 112. The slot 111 and the locking groove 112 can better guide and limit the movement of the locking component 130, so as to better realize the assembly and disassembly of the atomizing device 110 and the electronic control device 120.
[0049] Please see Figures 3 to 6The extended end of the locking end 131 is wedge-shaped and converges in the direction away from the electronic control device 120. The shape of the portion of the slot 111 near the opening is adapted to the shape of the extended end of the locking end 131. This facilitates the insertion of the extended end of the locking end 131 into the slot 111 and the locking groove 112.
[0050] Please see Figures 1 to 5 The operating end 133 extends out of the side of the electronic control device 120. This allows the user to easily operate the unlocking lock 130 by touching the operating end 133.
[0051] Please see Figures 3 to 6 The operating end 133 has a plate-like structure, and the thickness direction of the operating end 133 is perpendicular to the axis of the atomizing device 110. As a result, the area of the operating end 133 on the side away from the middle section 132 is relatively large, making it easier for the user to access and operate.
[0052] Please see Figure 4 and Figure 5 The locking end 131, near the middle section 132, is located within the first groove section 122, the middle section 132 is located within the second groove section 123, and the operating end 133, near the middle section 132, is located within the second groove section 123. Thus, the shape of the locking member 130 is adapted to the extending directions of the movable through groove 121, the slot 111, and the locking groove 112, thereby enabling the locking member 130 to perform its function.
[0053] Please see Figures 3 to 5 The elastic element 140 is a spring, and at least part of the elastic element 140 is located within the second groove segment 123. The extending direction of the elastic element 140 is consistent with the extending direction of the second groove segment 123. Thus, when the locking end 131 is located within the locking groove 112, the elastic element 140, which is in a compressed state, applies a force toward the bottom of the locking groove 112 to the locking member 130, thereby cooperating with the wall of the locking groove 112 to lock the locking end 131.
[0054] Please see Figures 3 to 6 The electronic cigarette 100 also includes a first limiting member 150, which is fitted inside the elastic member 140. The extending direction of the first limiting member 150 is consistent with the extending direction of the second groove segment 123. One end of the first limiting member 150 is connected to the operating end 133, and the other end of the first limiting member 150 is a free end. The first limiting member 150 is used to limit the movement of the elastic member 140 and the locking member 130. Thus, by limiting the movement of the elastic member 140 and the locking member 130 by the first limiting member 150, the assembly and disassembly of the atomizing device 110 and the electronic control device 120 are more effective.
[0055] Please see Figure 6The first limiting member 150 is columnar. Multiple recessed grooves are formed on the peripheral side of the first limiting member 150, arranged circumferentially. The extending direction of the multiple recessed grooves is parallel to the axial direction of the first limiting member 150. The arrangement of the multiple recessed grooves reduces the contact area between the first limiting member 150 and the elastic member 140, thereby reducing the difficulty of elastic deformation of the elastic member 140, and facilitating the assembly and disassembly of the atomizing device 110 and the electronic control device 120.
[0056] Please see Figures 3 to 6 The electronic cigarette 100 also includes a second limiting member 160, which is at least partially located within the second groove segment 123. The extending direction of the second limiting member 160 is consistent with the extending direction of the first limiting member 150. One end of the second limiting member 160 is connected to the operating end 133, and the other end is a free end. The second limiting member 160 is used to limit the locking member 130. Thus, by limiting and guiding the operating end 133 through the second limiting member 160, the movement of the locking member 130 is more stable, and the unlocking effect of the locking member 130 through the operating end 133 is better. The second limiting member 160 can be columnar or plate-shaped.
[0057] Please see Figures 3 to 6 Along the axial direction of the electronic control device 120, the intermediate section 132, the first limiting member 150, and the second limiting member 160 are arranged sequentially. As a result, the force on the operating end 133 is more even, and the limiting and guiding effect is better.
[0058] Please see Figures 1 to 5 The device has two slots 111, two locking slots 112, two locking pieces 130, and two movable through slots 121. The two slots 111 are located on opposite sides of the atomizing device 110, and the two movable through slots 121 are located on opposite sides of the electronic control device 120. These slots 111, locking slots 112, locking pieces 130, and movable through slots 121 are arranged in a one-to-one correspondence. This ensures a tight connection between the atomizing device 110 and the electronic control device 120, resulting in good connection positioning and guidance. It also accommodates the user's finger operation position, facilitating the detachment of the atomizing device 110 and the electronic control device 120.
[0059] Please combine Figures 3 to 5The assembly process of the atomizing device 110 and the electronic control device 120 of the electronic cigarette 100 of this application is as follows: The user inserts the locking end 131 into the slot 111 and brings the atomizing device 110 and the electronic control device 120 close to each other. When the locking end 131 passes through the locking groove 112, the elastic element 140 in the compressed state spontaneously drives the locking element 130 to move towards the bottom of the locking groove 112 through the opening of the locking groove 112. One side of the locking end 131 abuts against one side wall of the first groove segment 122, and the extended end of the locking end 131 abuts against the wall of the locking groove 112. Thus, the locking end 131 is locked by the wall of the locking groove 112 with the cooperation of the elastic element 140 and the movable through groove 121, and the atomizing device 110 and the electronic control device 120 are assembled. The process of detaching the atomizing device 110 and the electronic control device 120 is as follows: The user presses the operating end 133, and the locking member 130 moves toward the inside of the electronic control device 120 in the extension direction of the second groove 123. The first limiting member 150 and the second limiting member 160 move and abut against the groove wall of the first groove 122. The other side of the locking end 131 abuts against the other side wall of the first groove 122. The elastic member 140 is further compressed, and the locking end 131 disengages from the locking groove 112 through the opening of the locking groove 112. The locking member 130 is unlocked. While the user presses the operating end 133, the locking end 131 is taken out from the slot 111, and the atomizing device 110 and the electronic control device 120 are detached.
[0060] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application.
