A smoke exhaust pipe is provided at the top of the connecting tube. A smoke outlet channel corresponding to and communicating with the smoke exhaust pipe is opened in the mouthpiece. The slide groove is located on the rotation trajectory of the slot as the sleeve rotates. When the slot rotates counterclockwise along the outer wall of the connecting tube with the sleeve to correspond to the slide groove, the plug can be aligned with the slot. The sliding member slides in the slide groove to insert the plug into the slot again, so that the sleeve is connected to the connecting tube. The inner wall of the sleeve covers the oil plug and the through hole again.

[0010] In one embodiment, the atomizing body includes an oil storage tube, the upper end of which is narrowed to form the connecting tube, the upper end of which is narrowed to form the exhaust pipe, a groove is formed on the outer wall of the oil storage tube, and the upper end of the groove extends to the top of the oil storage tube, the sliding member is inserted into the groove from the top of the oil storage tube, and the plug is formed by the narrowing of the upper end of the sliding member.

[0011] In one embodiment, the sidewall of the slide groove is provided with a rail groove, and the sidewall of the sliding member is provided with a slide rail corresponding to the rail groove. The slide rail extends into the rail groove, and the sliding member is positioned in the slide groove by extending into the rail groove through the slide rail.

[0022] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0023] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described utility model content, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described.

[0024] like Figure 1-6 As shown, this utility model provides a concealed e-liquid atomizer, including an atomizing body 11 and a mouthpiece body 1. The mouthpiece body 1 has a slot 103. The atomizing body 11 has an oil storage chamber 306 for storing e-liquid. The atomizing body 11 has a child lock structure and an oil filling hole 303 communicating with the oil storage chamber 306 for filling with e-liquid. An oil plug 4 is provided in the oil filling hole 303 for sealing. The mouthpiece body 1 is detachably fitted onto the atomizing body 11 and covered with the oil plug 4. The child lock structure includes a groove 304 and a sliding member 5 provided in the groove 304, and a plug 501 provided on the sliding member 5 corresponding to the slot 103. The sliding member 5 slides in the groove 304 to insert the plug 501 into the slot 103, so that the mouthpiece body 1 is connected to the atomizing body 11. It should be noted that by covering the oil plug 4 with the mouthpiece body 1 and connecting the mouthpiece body 1 to the atomizing body 11 through the design of a child lock structure, the problem of the oil plug 4 being exposed outside the atomizer in the existing atomizer is solved. In the absence of parental supervision, children can pull out the oil plug 4 from the atomizer, causing the e-liquid in the oil storage chamber 306 to flow out of the atomizer from the oil filling hole 303, resulting in pollution and waste.

[0025] In some embodiments, the oil plug 4 is made of silicone or rubber and is hollow. A diaphragm 401 is provided in the hollow area of ​​the oil plug 4, and a through hole 402 communicating with the oil storage cavity 306 is provided on the diaphragm 401. The shape and diameter of the through hole 402 prevent e-liquid from passing through the oil storage cavity 306. In this embodiment, the oil plug 4 is made of rubber and has the characteristics of being deformable and automatically returning to its original shape after deformation, which can effectively seal the oil filling hole 303. The diaphragm 401 is used to prevent e-liquid from flowing out of the hollow area of ​​the oil storage cavity 306. Users can also inject e-liquid into the oil storage cavity 306 directly through the oil pipe of the e-liquid device inserted into the oil storage cavity 306 through the through hole 402 without removing the oil plug 4 from the oil filling hole 303.

[0026] In some embodiments, the through hole 402 is cross-shaped, the diameter of the through hole 402 is 0.2 mm, and the thickness of the diaphragm 401 is 0.4 mm. The through-hole 402 is cross-shaped. Both the oil plug 4 and the diaphragm 401 are made of rubber. When the oil pipe of the e-liquid device is inserted into the through-hole 402, the diaphragm 401 deforms, and the diameter of the through-hole 402 is greatly expanded. When e-liquid is injected into the e-liquid storage chamber 306, the air in the e-liquid storage chamber 306 will be discharged through the through-hole 402, allowing the e-liquid to quickly enter the e-liquid storage chamber 306 and accelerate the e-liquid injection efficiency. After the e-liquid is injected, the oil pipe of the e-liquid device is pulled out, and the diaphragm 401 will automatically return to its original shape, so that the diameter of the through-hole 402 returns to its original 0.2mm. The e-liquid in the e-liquid storage chamber 306 cannot pass through the 0.2mm diameter, ensuring that the e-liquid will not flow out. The diaphragm 401 is 0.4mm thick, which allows it to automatically recover quickly after deformation and is not easily punctured by the oil pipe of the e-liquid device.

[0027] In some embodiments, the mouthpiece body 1 includes a mouthpiece 101 and a sleeve 102 connected to each other. The mouthpiece 101 is formed by the necking of the upper end of the sleeve 102. A slot 103 is opened at the bottom end of the sleeve 102. A connecting tube 301 is provided on the atomizing body 11. An oil filling hole 303 is opened on the outer wall of the connecting tube 301. The mouthpiece body 1 is detachably fitted onto the atomizing body 11 through the sleeve 102 on the outer wall of the connecting tube 301. The mouthpiece body 1 is covered by an oil plug 4 and a through hole 402 through the inner wall of the sleeve 102. It should be noted that after the mouthpiece body 1 covers the oil plug 4 and the through hole 402 through the inner wall of the sleeve 102, the oil plug 4 will not be exposed, thus preventing children from pulling out the oil plug 4 and causing oil leakage. Users can expose the oil plug 4 by unplugging the sleeve 102 and the mouthpiece 101 connected to the connecting pipe 301, so that oil can be injected directly into the oil storage chamber 306 through the through hole 402, or the oil plug 4 can be pulled out and injected into the oil storage chamber 306 through the oil injection hole 303.

[0028] In some embodiments, the suction nozzle 101 can rotate along the outer wall of the connecting pipe 301 with the sleeve 102. The outer wall of the sleeve 102 has a window 104. The oil plug 4 and the through hole 402 are located on the rotation trajectory of the window 104 as the sleeve 102 rotates. The sliding member 5 can also pull the plug 501 out of the slot 103 by sliding in the slide groove 304. The window 104 rotates clockwise along the outer wall of the connecting pipe 301 with the sleeve 102 until the window 104 is directly above the slide groove 304, so that the oil plug 4 corresponds to the window 104 and the through hole 402 communicates with the window 104. It should be noted that, in conjunction with the above, the user can also inject oil into the oil storage chamber 306 without disconnecting the sleeve 102 and the suction nozzle 101 from the connecting pipe 301. By rotating the sleeve clockwise along the outer wall of the connecting pipe 301 until the window 104 corresponds to the oil plug 4, oil can be injected into the oil storage chamber 306 through the window 104 and the through hole 402. This reduces the number of steps required for oil injection and makes oil injection more convenient.

[0029] In some embodiments, at least one silicone ring 2 is provided between the outer wall of the connecting pipe 301 and the inner wall of the sleeve 102. The top end of the connecting pipe 301 is provided with a smoke exhaust pipe 302. The mouthpiece 101 has a smoke outlet channel 105 that corresponds to and communicates with the smoke exhaust pipe 302. The slide groove 304 is located on the rotation trajectory of the slot 103 as the sleeve 102 rotates. When the slot 103 rotates counterclockwise along the outer wall of the connecting pipe 301 with the sleeve 102 to correspond to the slide groove 304, the plug 501 can be aligned with the slot 103. The sliding member 5 can slide in the slide groove 304 to insert the plug 501 into the slot 103 again, so that the sleeve 102 is connected to the connecting pipe 301. The inner wall of the sleeve 102 is covered with the oil plug 4 and the through hole 402 again. It should be noted that, in conjunction with the above, after oil is injected into the oil storage chamber 306 through the window 104 and through hole 402, the sleeve 102 can be rotated counterclockwise until the slot 103 corresponds to the slide groove 304. At this time, the window 104 is separated from the oil plug 4 and through hole 402, and the inner wall of the sleeve 102 can continue to cover the oil plug 4 and through hole 402. Then, the sliding member 5 slides in the slide groove 304, and the plug 501 can be inserted into the slot 103, so that the sleeve 102 is connected to the connecting pipe 301. This prevents the oil plug 4 from being exposed and pulled out by children, and also prevents children from pulling the sleeve 102 off the connecting pipe 301. Among them, the silicone ring 2 is located at the upper and lower ends of the oil plug 4 respectively, and is used to reduce the sliding friction between the outer wall of the connecting pipe 301 and the inner wall of the sleeve 102, so that the sleeve 102 is easier to rotate on the connecting pipe 301. The exhaust pipe 302 is used to exhaust smoke, and the smoke outlet channel 105 is used to exhaust smoke.

[0030] In some embodiments, the atomizing body 11 includes an oil storage tube 3, with the upper end of the oil storage tube 3 constricted to form a connecting tube 301, and the upper end of the connecting tube 301 constricted to form a smoke exhaust tube 302. A groove 304 is formed on the outer wall of the oil storage tube 3, and the upper end of the groove 304 extends to the top of the oil storage tube 3. A sliding member 5 is inserted into the groove 304 from the top of the oil storage tube 3, and a plug 501 is formed by the constriction of the upper end of the sliding member 5. The oil storage tube 3, the connecting tube 301, and the smoke exhaust tube 302 are all cylindrical, which allows the sleeve 102 to rotate clockwise and counterclockwise on the connecting tube 301. The upper end of the groove 304 extends to the top of the oil storage tube 3, allowing the plug 501 to extend out of the groove 304 and insert into the slot 103 when the sliding member 5 slides in the groove 304, and also facilitating the sliding member 5 to rotate into the groove 304.

[0031] In some embodiments, the sidewall of the slide groove 304 is provided with a rail groove 305, and the sidewall of the sliding member 5 is provided with a slide rail 502 corresponding to the rail groove 305. The slide rail 502 extends into the rail groove 305, and the sliding member 5 is positioned in the slide groove 304 by extending into the rail groove 305 via the slide rail 502. The sliding member 5 can slide up and down within the slide groove 304 via the slide rail 502 and the rail groove 305. It should be noted that the cooperation between the slide rail 502 and the rail groove 305 ensures that the sliding member 5 will not fall out within the slide groove 304 and will not deviate from its sliding trajectory when sliding within the slide groove 304.

[0032] In some embodiments, the atomizing body 11 further includes an atomizing core 6 and a sealing member 7. The atomizing core 6 is disposed inside the oil storage pipe 3. The space between the outer wall of the atomizing core 6 and the inner wall of the oil storage pipe 3 and the connecting pipe 301 forms an oil storage cavity 306. The sealing member 7 is disposed inside the oil storage pipe 3 to seal the oil storage cavity 306. The exhaust pipe 302 corresponds to and communicates with the oil storage cavity 306. The upper end of the atomizing core 6 is inserted into the exhaust pipe 302 to block it. An air guiding channel 701 is provided on the sealing member 7. The lower end of the atomizing core 6 is inserted into the air guiding channel 701. The atomizing core 6 is used to atomize the e-liquid in the oil storage chamber 306. The sealing element 7 is made of silicone, which is soft and easy to assemble. It has a large deformation coefficient and can effectively seal the oil storage chamber 306. The upper end of the atomizing core 6 is inserted into the exhaust pipe 302 to isolate the exhaust pipe 302 from the oil storage chamber 306 and prevent the e-liquid in the oil storage chamber 306 from flowing out. The air guide channel 701 is used to provide the airflow required for atomizing the e-liquid to the atomizing core 6. The lower end of the atomizing core 6 is inserted into the air guide channel 701 to isolate the air guide channel 701 from the oil storage chamber 306 and also prevent the e-liquid in the oil storage chamber 306 from flowing out.

[0033] In some embodiments, the atomizing core 6 has an atomizing channel 601 that communicates with the air guide channel 701 and the exhaust pipe 302. The atomizing channel 601 is provided with a heating core 603. The outer wall of the atomizing core 6 has an oil inlet hole 602 corresponding to the heating core 603. The bottom end of the oil storage pipe 3 is provided with a fixing member 8. The bottom end of the fixing member 8 is provided with a first electrode 9 and a second electrode 10 that are electrically connected to the heating core 603, as well as an air inlet hole 801 that communicates with the air guide channel 701. The atomizing channel 601 is used to house the heating core 603 and the airflow. The heating core 603 is used to heat the e-liquid in the oil storage chamber 306 to produce smoke. The oil inlet 602 is used to guide the e-liquid in the oil storage chamber 306 into the heating core 603. The fixing member 8 is used to seal the bottom end of the oil storage tube 3 and prevent the sealing member 7 from moving down. The first electrode 9 and the second electrode 10 are used to connect the heating core 603 to electricity so that it can heat up. When the mouthpiece 101 is used to smoke, the external airflow can enter the air guide channel 701 through the air inlet 801, and then enter the atomizing channel 601 through the air guide channel 701. Then, it drives the smoke generated by the heating core 603 heating the e-liquid to enter the exhaust pipe 302, and finally enter the user's mouth through the smoke outlet channel 105 to be inhaled.

[0034] The following detailed description uses preferred embodiments.

[0035] like Figure 1-6As shown, the atomizer of this utility model includes: a mouthpiece body 1 and an atomizing body 11. The atomizing body 11 includes: a silicone ring 2, an oil storage tube 3, an oil plug 4, a sliding member 5, an atomizing core 6, a sealing member 7, a fixing member 8, a first electrode 9, and a second electrode 10. The upper end of the oil storage tube 3 is necked to form a connecting tube 301 for connecting to the mouthpiece body 1. The upper end of the connecting tube 301 is also necked to form an exhaust tube 302 for exhausting smoke. The atomizing core 6 is installed inside the oil storage tube 3. The space between the outer wall of the atomizing core 6 and the inner walls of the oil storage tube 3 and the connecting tube 301 forms an oil storage cavity 306 for storing e-liquid. The atomizing core 6 is used to atomize the e-liquid in the oil storage cavity 306. The upper end of the atomizing core 6 is inserted into the exhaust tube 302 to isolate the exhaust tube 302. The oil storage chamber 306 and the sealing element 7 are installed inside the oil storage pipe 3 to seal the oil storage chamber 306. The sealing element 7 has an air guide channel 701 for air guiding. The lower end of the atomizing core 6 is inserted into the air guide channel 701 to isolate the air guide channel 701 and the oil storage chamber 306. The atomizing core 6 has an atomizing channel 601 that communicates with the air guide channel 701 and the exhaust pipe 302 for airflow. The atomizing channel 601 has a heating element 603 to heat the e-liquid in the oil storage chamber 306 to produce smoke. The outer wall of the atomizing core 6 has an oil inlet hole 602 corresponding to the heating element 603 to guide the e-liquid in the oil storage chamber 306 into the heating element 603. The fixing element 8 is installed at the bottom end of the oil storage pipe 3 to seal the bottom end of the oil storage pipe 3. The bottom end of the fixing component 8 is provided with a first electrode 9 and a second electrode 10 electrically connected to the heating core 603 for energizing the heating core 603 to generate heat. The bottom end of the fixing component 8 has an air inlet 801 communicating with the air guide channel 701 for external airflow to enter the air guide channel 701. A silicone ring 2 is fitted onto the outer wall of the connecting pipe 301. The outer wall of the connecting pipe 301 has an oil injection hole 303 communicating with the oil storage cavity 306 for injecting oil into the oil storage cavity 306. An oil plug 4 is inserted into the oil injection hole 303 to seal it. The oil plug 4 is hollow, and a diaphragm 401 is provided in the hollow area of ​​the oil plug 4 to prevent e-liquid from flowing out of the oil storage cavity 306. A through hole 402 communicating with the oil storage cavity 306 is also provided on the diaphragm 401. For injecting oil into the oil storage chamber 306, the outer wall of the oil storage pipe 3 is provided with a groove 304 extending to the top of the oil storage pipe 3 for accommodating the sliding member 5 to slide inside. The sliding member 5 is inserted into the groove 304 from the top of the oil storage pipe 3. The upper end of the sliding member 5 is necked to form a plug 501 for connecting the mouthpiece body 1 to the connecting pipe 301. The side wall of the groove 304 is provided with a rail groove 305. The side wall of the sliding member 5 is provided with a rail 502 corresponding to the rail groove 305. The rail 502 extends into the rail groove 305. The sliding member 5 is positioned in the groove 304 by extending into the rail groove 305 through the rail 502. The sliding member 5 can slide up and down in the groove 304 through the rail 502 and the rail groove 305. All components are combined together to form the atomizing body 11.

[0036] The mouthpiece body 1 includes a mouthpiece 101 and a sleeve 102 connected to each other. The mouthpiece 101 is formed by the necking of the upper end of the sleeve 102. The bottom end of the sleeve 102 has a slot 103. The mouthpiece body 1 is detachably fitted onto the atomizing body 11 through the sleeve 102 on the outer wall of the connecting tube 301. The slot 103 corresponds to the plug 501 on the sliding member 5. The silicone ring 2 abuts against the inner wall of the sleeve 102 to reduce the sliding friction between the outer wall of the connecting tube 301 and the inner wall of the sleeve 102. The mouthpiece body 1 is covered by the oil plug 4 and the through hole 402 through the inner wall of the sleeve 102 to prevent the oil plug 4 from being exposed and pulled out by children, causing oil leakage. The sliding member 5 slides upward in the sliding groove 304 to insert the plug 501 into the slot 103, so that the sleeve 102 is connected to the connecting tube 301.

[0037] The suction nozzle 101 can rotate along the outer wall of the connecting pipe 301 with the sleeve 102. The outer wall of the sleeve 102 has a window 104. The oil plug 4 and the through hole 402 are located on the rotation trajectory of the window 104 as the sleeve 102 rotates. The sliding member 5 slides downward in the slide groove 304 to pull the plug 501 out of the slot 103. The window 104 rotates clockwise along the outer wall of the connecting pipe 301 with the sleeve 102 until the window 104 is directly above the slide groove 304, so that the oil plug 4 corresponds to the window 104. The through hole 402 communicates with the window 104. The oil pipe of the oil injection device can inject oil into the oil storage chamber 306 through the window 104 and the through hole 402. At the same time as oil injection, the air in the oil storage chamber 306 can be discharged from the through hole 402 to speed up the oil injection efficiency, thereby reducing the oil injection steps and making the oil injection operation more convenient.

[0038] After the oil is filled, the sleeve 102 can be rotated counterclockwise until the slot 103 corresponds to the slide groove 304. At this time, the window 104 is separated from the oil plug 4 and the through hole 402. The inner wall of the sleeve 102 can continue to cover the oil plug 4 and the through hole 402. Then, the slider 5 slides in the slide groove 304 and the plug 501 can be inserted into the slot 103, so that the sleeve 102 is connected to the connecting tube 301.
