AI Technical Summary
Existing e-cigarettes are prone to damage to the atomizer core due to user misoperation, especially during the first use when the air intake is open while the oil intake is closed. This causes the heating wire of the atomizer core to heat the oil-free wicking cotton, resulting in damage.
By designing an exhaust pipe that can rotate around its own axis, the positions of the air inlet and oil inlet are constructed to be at an angle to each other. When the exhaust pipe rotates to different states, the air inlet and oil inlet are connected or closed respectively, avoiding damage caused by misoperation.
This ensures the lifespan of the e-cigarette, prevents damage to the atomizer core due to misoperation, and improves the reliability and stability of the e-cigarette.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0033] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.
[0034] Based on the description in the background art, it can be known that the existing electronic cigarette cannot realize the simultaneous opening and closing of the air inlet hole 331 and the oil inlet hole 332, and is prone to the state that the air inlet hole 331 is opened and the oil inlet hole 332 is closed. This state is particularly prone to occur when the user uses the electronic cigarette for the first time after purchasing it. The user directly smokes due to lack of experience, the microphone directly works, and the heating wire of the atomizer directly heats the oil guide cotton 700 without oil, thereby causing damage to the atomizer. In view of this, the present embodiment provides an electronic cigarette, which aims to realize the synchronous opening and closing of the air inlet hole 331 and the oil inlet hole 332 by improving the structure of the air inlet pipe, so as to prevent the state that one of them is opened and the other is closed.
[0035] Specifically, in combination with the accompanying Figure 1 and 2 As shown in the drawings, the upper structure of the electronic cigarette provided by the present embodiment includes an oil cup 100, a mouthpiece 200, an air outlet pipe 300, a base 400, and a shell 500. The upper structure of the electronic cigarette includes an oil cup 100, a mouthpiece 200, etc. The lower structure of the electronic cigarette includes a battery outer tube, an electric core (not shown in the figure), etc. At least part of the upper structure and the lower structure is located in the shell 500 of the present embodiment. Since the improvement of the electronic cigarette of the present embodiment lies in the upper structure, the present embodiment does not describe and illustrate the lower structure of the electronic cigarette too much. In addition, the drawings of the present embodiment only show the upper structure of the electronic cigarette. Figure 2 , the drawings of the present embodiment only show the upper structure of the electronic cigarette. Figure 3 and the drawings of the present embodiment only show the upper structure of the electronic cigarette. Figure 4 and the drawings of the present embodiment only show the upper structure of the electronic cigarette.
[0036] The oil cup 100 is a mounting base of the upper parts of the electronic cigarette. The mouthpiece 200 is mounted at the upper end of the oil cup 100 and is used for the user to inhale. The air outlet pipe 300 is mounted in the oil cup 100, and the air outlet pipe 300 and the oil cup 100 can be coaxially arranged. The atomization assembly is mounted in the air outlet pipe 300. The base 400 is mounted at the bottom end of the oil cup 100. Part of the base 400 extends into the oil cup 100 and is sleeved outside the lower end of the air outlet pipe 300. The microphone (not shown in the figure) penetrates through the base 400 and is connected with the atomization assembly to open and close the atomization operation of the atomization assembly.
[0037] Different from the existing electronic cigarette structure, the air outlet pipe 300 of the electronic cigarette can rotate around the axis thereof. The air inlet hole 331 and the oil inlet hole 332 are arranged on the wall of the air outlet pipe 300. The air outlet hole 410 and the oil outlet hole 420 are arranged on the base 400. The positional relationship between the air inlet hole 331 and the air outlet hole 410 and the positional relationship between the oil inlet hole 332 and the oil outlet hole 420 are configured as follows: when the air outlet pipe 300 rotates to the first state, as shown in FIG. 4a, the air inlet hole 331 of the air outlet pipe 300 is in communication with the air outlet hole 410 of the base 400, and as shown in FIG. 4b, the oil inlet hole 332 of the air outlet pipe 300 is in communication with the oil outlet hole 420 of the base 400. When the air outlet pipe 300 rotates to the second state, as shown in FIG. 4c, the communication between the air inlet hole 331 and the air outlet hole 410 is closed, and as shown in FIG. 4d, the communication between the oil inlet hole 332 and the oil outlet hole 420 is closed. Figure 2 Figure 4 Figure 3 Figure 5
[0038] The electronic cigarette with the above structure improves the structure of the air outlet pipe 300 and the base 400, so that the rotation of the air outlet pipe 300 can simultaneously open and close the oil inlet hole 332 and the air inlet hole 331, avoid the state that the air inlet hole 331 is opened and the oil inlet hole 332 is closed, prevent the atomization core from being damaged due to the user's misoperation, and ensure the service life of the electronic cigarette.
[0039] It should be noted that the Figure 2 and Figure 4 are different angle cross sections of the upper structure of the electronic cigarette of the embodiment. Similarly, the Figure 3 and Figure 5 are different angle cross sections of the upper structure of the electronic cigarette of the embodiment. That is, the oil inlet hole 332 and the air inlet hole 331 of the embodiment are not in a straight line in the vertical direction, or it can be understood that when the number of the air inlet hole 331 and the oil inlet hole 332 is two, the projection of the connecting line between the two oil inlet holes 332 on the base 400 is a first line segment, the projection of the connecting line between the two air inlet holes 331 on the base 400 is a second line segment, and the first line segment and the second line segment form an angle with each other.
[0040] The reason for such design is to avoid the interference between the oil inlet and the air inlet, and preferably, the first line segment and the second line segment are designed to be perpendicular, and a gear mark (not shown in the figure) is designed on the oil cup 100 of the electronic cigarette, when the air inlet hole 331 and the oil inlet hole 332 are switched from the open state to the closed state, the air outlet pipe 300 of the embodiment is twisted by 90°, and similarly, when the air inlet hole 331 and the oil inlet hole 332 are switched from the closed state to the open state, the air outlet pipe 300 is reversed or twisted again by 90°, which is very convenient for the user to operate, and the opening and closing is accurate.
[0041] In order to facilitate the rotation of the air outlet pipe 300 around its own axis, as a preferred embodiment of the present embodiment, the mouthpiece 200 is rotatably mounted on the upper end of the oil cup 100, and the upper end of the air outlet pipe 300 is connected with the mouthpiece 200, so that the rotation of the mouthpiece 200 can drive the air outlet pipe 300 to rotate synchronously, without the need to add other structures. The specific connection between the mouthpiece 200 and the upper end of the oil cup 100 can be sleeve connection. Preferably, the upper end of the air outlet pipe 300 of the present embodiment is inserted into the mouthpiece 200 and connected with the mouthpiece 200 by key (the key connection structure is not shown in the figure), which not only facilitates the connection and assembly of the two, but also can improve the stability of the connected structure and avoid loosening of the two.
[0042] In addition, the present embodiment is provided with a limiting flange 311 extending outwardly on the upper part of the air outlet pipe 300, and the oil cup 100 is provided with a limiting tube 110, the inner wall of the limiting tube 110 is provided with a first limiting edge 111 and a second limiting edge 112, and the limiting flange 311 is located between the first limiting edge 111 and the second limiting edge 112. The cooperation of the first limiting edge 111, the second limiting edge 112 and the limiting flange 311 can prevent the air outlet pipe 300 from moving, and ensure the stability of the air outlet pipe 300 in the oil cup 100.
[0043] In addition, as a preferred embodiment of the present embodiment, the central angle corresponding to the circumferential length of the first limiting edge 111 above the limiting tube 110 is preferably less than 180°, and the circular angle corresponding to the circumferential length of the limiting flange 311 of the present embodiment can also be less than or equal to 180°, or the sum of the central angle corresponding to the first limiting edge 111 and the circular angle corresponding to the limiting flange 311 is 360°. In this way, the limiting flange 311 can be avoided by rotating the air outlet pipe 300 to avoid the first limiting edge 111, thereby facilitating the insertion of the air outlet pipe 300 into the oil cup 100, and then rotating the air outlet pipe 300 to make the first limiting edge 111 and the limiting flange 311 limit and cooperate to complete the assembly.
[0044] In addition, in order to improve the sealing between the air inlet pipe and the inner wall of the oil cup 100, and improve the stability of the limiting flange 311 between the first limiting edge 111 and the second limiting edge 112, at least one mounting groove 3111 is arranged on the outer wall of the limiting flange 311, and a sealing ring 312 is mounted in the mounting groove 3111. The sealing ring 312 is in sealing cooperation with the inner wall of the limiting pipe 110 and the bottom wall of the mounting groove 3111, respectively, and plays a role of sealing and fixing the air outlet pipe 300 of the embodiment. The material of the sealing ring 312 can be rubber or silicone.
[0045] In order to facilitate the installation of the heating wire 600 and the oil guiding cotton 700 and other atomization components, the air outlet pipe 300 of the embodiment comprises a first straight pipe section 310, a variable diameter section 320 and a second straight pipe section 330 connected in sequence from top to bottom. The radial dimension of the second straight pipe section 330 is greater than that of the first straight pipe section 310. That is, the radial dimension of the variable diameter section 320 of the embodiment gradually increases in the direction from the first straight pipe section 310 to the second straight pipe section 330. The air inlet hole 331 and the oil inlet hole 332 are both arranged on the second straight pipe section 330.
[0046] The limiting flange 311 described above is arranged on the outer wall of the first straight pipe section 310 of the embodiment, and the heating wire 600 and the oil guiding cotton 700 are mounted in the second straight pipe section 330 of the embodiment. The gasket 800 is mounted at the bottom end of the second straight pipe section 330. The oil guiding cotton 700 of the embodiment is sleeved on the heating wire 600 and communicates with the oil inlet hole 332. The bottom end of the gasket 800 of the embodiment is in sealing cooperation with the inner wall of the bottom end of the second straight pipe section 330, and the side wall of the gasket 800 is in clearance cooperation with the air inlet hole 331. The material of the gasket 800 of the embodiment and the base 400 can be a deformable material such as silicone.
[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
