[0025] Please also read Figure 3 and Figure 4In the present embodiment, an atomizing channel 120 is provided inside the oil storage tank body 100, and the atomizing channel 120 has a first opening 122 communicating with the outside, and a third opening 124 communicating with the oil storage chamber 110. The cigarette holder assembly 200 comprises a rotating shell 210, a connecting tube body 220 and a riveted joint 230, wherein the rotating shell 210 is rotatably arranged on the outer wall of the oil storage tank body 100, the connecting tube body 220 is arranged on the rotating shell 210 and extends into the atomizing channel 120 through the first opening 122, the riveted joint 230 is arranged in the oil storage chamber 110 and extends into the atomizing channel 120 through the third opening 124, one end of the riveted joint 230 extending into the atomizing channel 120 is riveted and fastened to the inner side of one end of the connecting tube body 220 extending into the atomizing channel 120, and the rotating shell 210 abuts against the axial limit of the atomizing channel 120 toward the oil storage chamber 110. On the outer wall of the oil storage tank body 100, the rivet joint 230 is axially limited along the atomization channel 120 away from the oil storage chamber 110 and abuts against the inner wall of the oil storage chamber 110, so that the axial limit of the rotating shell 210, the connecting tube body 220 and the riveted joint 230 along the atomization channel 120 is realized, so that the rotating shell 210, the connecting tube body 220 and the riveted joint 230 can only rotate along the circumferential direction of the atomization channel 120, but cannot rotate along the atomization channel 120. The channel 120 moves axially, and the rotating shell 210 is finally pressed on the side of the limiting cover body 410 facing away from the oil storage tank body 100, and when the rotating shell 210 rotates to the first position, the rotating shell 210 is immediately pressed on the side of the liquid injection cover body 310 facing away from the oil storage tank body 100, and when the rotating shell 210 rotates to the second position, the rotating shell 210 immediately avoids the side of the liquid injection cover body 310 facing away from the oil storage tank body 100.

[0026] See also Figure 7c In this embodiment, the rotating shell 210 and the connecting tube body 220 are integrally formed, and a connecting channel 211 communicating with the connecting tube body 220 is provided inside the rotating shell 210. One end of the connecting channel 211 facing away from the connecting tube body 220 passes through the top of the rotating shell 210 to form a fifth opening 213. The mouthpiece plug body 270 is pluggably arranged on the connecting channel 211 and closes the fifth opening 213.

[0027] Specifically, the connecting channel 211 is used to guide the atomized aerosol in the oil storage chamber 110 to the fifth opening 213 via the riveted joint 230, the third opening 124, and the connecting tube 220 for the user to inhale. The mouthpiece plug 270 is disposed on the fifth opening 213 and can be detachably connected by plugging and unplugging operations, so that the user can easily pull out or re-insert the mouthpiece plug 270 into the fifth opening 213.

[0028] It should be noted that the mouthpiece plug body 270 is made of a flexible material to ensure good sealing during insertion, and at the same time, it is convenient for users to insert and remove it by applying an appropriate force. In addition, to ensure that the rotation of the rotating housing 210 in the circumferential direction does not affect the stability of the mouthpiece plug body 270, the mouthpiece plug body 270 can form a reliable mating seal with the connection channel 211 in the inserted state, preventing the leakage or loss of the atomized products of the e-liquid, and further improving the use experience and reliability of the portable electronic cigarette 10.

[0029] Furthermore, in this embodiment, the above-mentioned mouthpiece assembly 200 further includes a fastening collar 240. The fastening collar 240 is located in the atomization channel 120 and is disposed around the outer wall of the end of the connecting pipe body 220 extending into the atomization channel 120. The fastening collar 240 is used to radially lock and rivet the end of the riveting joint 230 extending into the atomization channel 120 to the inner side of the end of the connecting pipe body 220 extending into the atomization channel 120 along the atomization channel 120, so as to prevent the end of the riveting joint 230 extending into the atomization channel 120 from being accidentally separated from the end of the connecting pipe body 220 extending into the atomization channel 120 along the axial direction of the atomization channel 120.

[0030] Furthermore, in this embodiment, the above-mentioned mouthpiece assembly 200 further includes an elastic collar 250. The atomization channel 120 is coaxially provided with a fixed ring groove 126. The fixed ring groove 126 directly communicates with the oil storage chamber 110 along the axial direction of the atomization channel 120 facing the oil storage chamber 110. The elastic collar 250 is disposed around the outer wall of the connecting pipe body 220 and is embedded in the fixed ring groove 126. The inner ring of the elastic collar 250 is elastically abutted against the outer wall of the fastening collar 240, and the outer ring of the elastic collar 250 is elastically abutted against the inner wall of the fixed ring groove 126. A limiting ring portion 232 is coaxially disposed around the outer wall of the riveting joint 230. The limiting ring portion 232 is located in the oil storage chamber 110, and the limiting ring portion 232 abuts against the inner wall of the oil storage chamber 110 along the axial direction of the atomization channel 120 facing away from the oil storage chamber 110, and limits and abuts the elastic collar 250 in the fixed ring groove 126.

[0031] It should be noted that, in this embodiment, the outer ring of the above-mentioned elastic collar 250 is elastically abutted against the inner wall of the fixed ring groove 126, and the inner ring of the elastic collar 250 is elastically abutted against the outer wall of the fastening collar 240. On the one hand, the elastic collar 250 is used to increase the rotational friction force of the connecting pipe body 220 in the atomization channel 120 in the circumferential direction of the atomization channel 120, thereby preventing the rotating housing 210 of the mouthpiece assembly 200 from accidentally rotating and inadvertently opening the second opening 132 during the carrying process of the portable electronic cigarette 10. On the other hand, the elastic collar 250 is also used to seal the atomization channel 120, thereby preventing the e-liquid in the oil storage chamber 110 from leaking out of the atomization channel 120.

[0032] Specifically, in the present embodiment, the outer ring of the elastic ring 250 is provided with a friction surface (not shown in the figure), and the inner ring of the elastic ring 250 has a smooth surface (not shown in the figure). It can be understood that the friction surface has a higher friction coefficient than the smooth surface. In this way, the elastic ring 250 is relatively fixedly embedded in the fixed ring groove 126, and when the connecting tube body 220 rotates circumferentially along the atomization channel 120, the elastic ring 250 is not easy to rotate accordingly with the connecting tube body 220.

[0033] It should be noted that, in the present embodiment, the above-mentioned fixed annular groove 126 is directly connected to the oil storage chamber 110 along the axial direction of the atomizing channel 120 toward the oil storage chamber 110, and the limiting ring portion 232 abuts against the inner wall of the oil storage chamber 110 along the axial direction of the atomizing channel 120 away from the oil storage chamber 110, and the limiting abutment elastic sleeve 250 is in the fixed annular groove 126. On the one hand, the limiting ring portion 232 is used to cooperate with the bottom of the rotating shell 210 to realize the axial limitation of the rotating shell 210, the connecting tube body 220 and the riveted joint 230 along the atomizing channel 120. On the other hand, the limiting ring portion 232 is used to assist the elastic ring 250 in limiting and fixing in the fixed ring groove 126. In this way, during the assembly process of the portable electronic cigarette 10, the elastic ring 250 can be extended from one side of the oil storage chamber 110 into the fixed ring groove 126 and arranged on the outer wall of the fastening ring 240, and then the riveted joint 230 is extended from one side of the oil storage chamber 110 into the atomization channel 120 and riveted to the connecting tube body 220. At the same time, the limiting ring part 232 on the riveted joint 230 synchronously limits and fixes the elastic ring 250 in the fixed ring groove 126, thereby realizing a convenient assembly process of the portable electronic cigarette 10.

[0035] Specifically, in this embodiment, the outer wall of the top of the oil storage tank body 100 is provided with two sections of limiting arc grooves 150, and the two sections of limiting arc grooves 150 are arranged symmetrically with the first opening 122, and the bottom of the rotating shell 210 is correspondingly provided with two limiting protrusions 212 that extend into the two sections of limiting arc grooves 150 in a one-to-one manner.

[0036] Please also read Figure 8 and Figure 9 In this embodiment, the above-mentioned liquid injection plug cover 300 includes a liquid injection cover body 310 and a liquid injection plug body 320 fixedly arranged on the liquid injection cover body 310, and the limit plug cover 400 includes a limit cover body 410 and a limit plug body 420 fixedly arranged on the limit cover body 410. The liquid injection cover body 310 is adjacent to the limit cover body 410, and the liquid injection cover body 310 and the limit cover body 410 are tightly fitted on the outer wall of the oil storage tank body 100. The liquid injection plug body 320 is correspondingly inserted into the first opening 122, and the limit plug body 420 is correspondingly inserted into the limit counterbore 140. The rotating shell 210 is always pressed on the side of the limit cover body 410 facing away from the oil storage tank body 100, and the limit plug body 420 is always relatively locked in the limit counterbore 140, that is, the limit plug body 420 is always fixedly inserted in the limiting counterbore 140, and when the rotating shell 210 rotates to the first position, the rotating shell 210 is immediately pressed on the side of the liquid injection cover 310 facing away from the oil storage tank body 100, and the liquid injection plug 320 is correspondingly locked in the second opening 132, that is, the liquid injection plug 320 is fixedly inserted in the second opening 132, and when the rotating shell 210 rotates to the second position, the rotating shell 210 is immediately avoided by the side of the liquid injection cover 310 facing away from the oil storage tank body 100, and the liquid injection plug 320 is correspondingly unlocked in the second opening 132, that is, the liquid injection plug 320 is movably inserted in the second opening 132, at this time, the liquid injection cover 310 is opened and the liquid injection plug 320 can be pulled out of the second opening 132.

[0037] In this embodiment, the above-mentioned liquid injection cover body 310 and the limiting cover body 410 are integrally formed, the liquid injection plug body 320 is integrally formed on the liquid injection cover body 310, and the limiting plug body 420 is integrally formed on the limiting cover body 410. The outer wall of the top of the oil storage tank body 100 is provided with a cover body groove 160, and the positioning countersunk hole and the second opening 132 are both provided in the cover body groove 160. The liquid injection cover body 310 and the limiting cover body 410 are adapted to fit in the cover body groove 160 together. In this way, the outer surface of the oil storage tank body 100 remains flat, which is convenient for the rotating shell 210 to be pressed accordingly on the side of the liquid injection cover body 310 facing away from the oil storage tank body 100 and the side of the limiting cover body 410 facing away from the oil storage tank body 100, thereby closing the second opening 132 without affecting the overall appearance of the product, thereby improving the integration and aesthetics of the product.

[0038] Please also read Figure 5 and Figure 10a, in this embodiment, the portable electronic cigarette 10 further includes a cross plug cover 500. An injection channel 130 is further provided inside the oil storage chamber 100, which has a second opening 132 communicating with the outside and a fourth opening 134 communicating with the oil storage chamber 110. The cross plug cover 500 is embedded in the fourth opening 134 to block the fourth opening 134. The cross plug cover 500 is an elastic plug cover and has a cross indentation 512 for forming a cross slit after being punctured.

[0039] It should be noted that, in this embodiment, the cross indentation 512 is a preset thin layer area for forming a cross slit when punctured by an external injection device. Before the first injection, the cross plug cover 500 is in a completely closed state. Only when the user opens the injection plug cover 300 and inserts an injection device into the injection channel 130 through the second opening 132 and punctures the cross indentation 512, the cross indentation 512 immediately forms a cross slit to enable the injection device to communicate with the oil storage chamber 110 through the second opening 132 for injection operation. And when the injection device is removed, the cross slit can quickly rebound and reset under its own elastic force to block the fourth opening 134.

[0040] In this embodiment, in order to ensure that the cross plug cover 500 can quickly rebound and reset and reliably block the fourth opening 134 after the external injection device is pulled out, the cross plug cover 500 is integrally formed of high-elastic silicone or an elastomeric material with similar elastic properties. Preferably, the Shore hardness of the elastomeric material is controlled between 30A and 50A to balance the puncture convenience and the sealing and rebounding performance.

[0041] It can be understood that the above injection plug cover and the cross plug cover 500 respectively block the second opening 132 and the fourth opening 134 of the injection channel 130, thereby forming a double sealing effect on the injection channel 130, which can prevent the e-liquid from accidentally leaking out of the injection channel 130 and effectively improve the use experience of the portable electronic cigarette 10.

[0042] In addition, in practical applications, the material of the cross plug cover 500 has good oil resistance and heat resistance to ensure long-term elasticity and sealing performance under different ambient temperatures and oil erosion.

[0043] Please refer to Figure 5 、 Figure 6 and Figure 10b, in this embodiment, the above-mentioned portable electronic cigarette 10 further includes a limiting ring tube 600. Inside the liquid injection channel 130, there is a limiting ring platform 136 coaxially arranged outside the fourth opening 134. The limiting ring tube 600 abuts against the cross plug cover 500 along the axial direction of the liquid injection channel 130 and is fixed on the limiting ring platform 136, thereby providing a fastening effect on the cross plug cover 500, preventing the cross plug cover 500 from accidentally moving inside the liquid injection channel 130 when subjected to external forces or air pressure changes, and ensuring the sealing effect of the cross plug cover 500 on the fourth opening 134.

[0044] Please refer to Figure 10a and Figure 10b , in this embodiment, the above-mentioned cross plug cover 500 includes a cross plug body 510 having a cross indentation 512, and a first convex ring 520 coaxially arranged outside the cross plug body 510. A first concave ring 514 is formed between the cross plug body 510 and the first convex ring 520. One corresponding end of the limiting ring tube 600 is provided with a second convex ring 610, and a second concave ring 620 arranged outside the second convex ring 610. The limiting ring platform 136 is provided with a limiting ring groove 138 arranged outside the second opening 132. The first convex ring 520 is inserted into the second concave ring 620 on the side facing the second concave ring 620, the second convex ring 610 is inserted into the first concave ring 514 on the side facing the first concave ring 514, and the side of the first convex ring 520 facing the limiting ring platform 136 is inserted into the limiting ring groove 138. In this way, the cross plug cover 500 and the limiting ring tube 600 form a ring sleeve structure, further improving the fixing effect of the cross plug cover 500 along the axial direction of the liquid injection channel 130, preventing the cross plug cover 500 from shifting due to external forces such as the insertion force of the liquid injection device, pressure fluctuations in the oil storage chamber 110, or transportation shaking, resulting in changes in the position of the cross indentation 512, misalignment of the sealing surface, or failure of the sealing function.

[0045] In addition, in this embodiment, the limiting ring groove 138 can provide a positioning constraint for the cross plug cover 500 along the axial direction of the liquid injection channel 130, ensuring that the cross plug cover 500 is always in a preset sealing position and guaranteeing the continuous effectiveness of the sealing function. In addition, the limiting ring groove 138 can also assist in installation positioning. During the assembly process of the electronic cigarette, the limiting ring groove 138 provides a clear insertion alignment reference for the first convex ring 520, enabling the cross plug cover 500 to be quickly positioned and automatically in place during installation, improving the assembly efficiency and consistency, and reducing manual errors.

[0046] Furthermore, in this embodiment, the above-mentioned portable electronic cigarette 10 further includes a battery compartment 700. The battery compartment 700 is snap-fitted to one end of the oil storage chamber 100 facing away from the mouthpiece assembly 200.

[0047] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
