Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] like Figures 1 to 9 As shown, this embodiment provides a leak-proof electronic cigarette, including: an upper oil cup 11 and a lower oil cup 21 distributed vertically. The bottom opening of the upper oil cup 11 is sealed by a silicone plate A12 to form an oil storage cavity 1, and the bottom opening of the lower oil cup 21 is sealed by a silicone plate B22 to form an oil storage cotton cavity 2. Specifically, the oil storage cavity 1 is used to hold e-liquid, while the oil storage cotton cavity 2 is filled with oil storage cotton 4. More specifically, the upper oil cup 11 is a transparent oil cup, making it easy to observe the amount of oil in the oil storage cavity 1. The oil inlet hole at the bottom of the silicone plate A12 is sealed by a silicone nail 121, which facilitates the addition of e-liquid, and the silicone nail 121 achieves a good seal.

[0027] The atomizing core 3 is installed at the top of the lower oil cup 21. The bottom of the atomizing core 3 is sealed by the silicone plate B22. That is, the silicone plate B22 seals the lower opening of the lower oil cup 21 and also blocks the bottom of the atomizing core 3. The atomizing core 3 has pores for entering e-liquid on its side. When the side of the atomizing core 3 is wrapped by the e-liquid-absorbing cotton 4, the e-liquid in the cotton 4 seeps into the atomizing core 3.

[0028] Please see Figure 3 and Figure 8As shown, the top of the atomizing core 3 is connected to the air tube 31. The air tube 31 passes through the silicone plate A12 and is connected to the mouthpiece 111 provided on the top of the upper oil cup 11. The mouthpiece 111 is only integrally connected to the top of the air tube 31 and is not connected to the inside of the upper oil cup 11. After the atomizing core 3 heats and atomizes the e-liquid inside, it is inhaled into the user's mouth through the air tube 31 and the mouthpiece 111. Specifically, a connecting tube 211 is integrally connected to the top of the lower oil cup 21, and the lower end of the connecting tube 211 is connected to the top of the atomizing core 3; an air tube hole is opened on the upper surface of the silicone plate A12, and an annular groove corresponding to the connecting tube 211 is opened on the lower surface of the silicone plate A12. The annular groove is located outside the air tube hole to form a sealing sleeve 122, that is, a sealing sleeve 122 is formed between the annular groove and the air tube hole. The top of the connecting tube 211 is matched and installed in the annular groove, and the bottom end of the connecting tube 211 is installed in the air tube hole; by providing a sealing sleeve 122 on the silicone plate A12, a good seal is achieved when the connecting tube 211 is connected to the atomizing core 3, which is convenient and practical.

[0029] The lower oil cup 21 is filled with oil-retaining cotton 4, which wraps around the side of the atomizer core 3. When the oil-retaining cotton 4 absorbs e-liquid, the e-liquid in the oil-retaining cotton 4 can enter the interior of the atomizer core 3 through the pores on the side of the atomizer core 3. Several fiber rods 5 are vertically inserted into the oil-retaining cotton 4. The top of the fiber rods 5 passes through the upper oil cup 11 and the silicone plate A12 and extends into the oil-retaining cavity 1. In fact, the fibers forming the fiber rods 5 include, but are not limited to, plastic fibers, cotton fibers, metal fibers, and inorganic non-metallic fibers. The fiber rods 5 can slowly transfer the e-liquid in the oil-retaining cavity 1 to the oil-retaining cotton 4 in the oil-retaining cotton cavity 2, so that the oil-retaining cotton 4 can absorb and deliver it to the atomizer core 3. Furthermore, the oil-retaining cotton 4 inside the oil-retaining chamber 2 has a high-molecular fiber structure. Its loose and porous properties serve as an excellent liquid storage medium carrier. It not only utilizes the surface tension of the e-liquid to lock it within the oil-retaining cotton, but also slowly supplies the e-liquid to the atomizer core through its internal capillary channels, thereby achieving an effective balance between the e-liquid received in the atomizer core and the e-liquid that evaporates during atomization. At the same time, the oil-retaining chamber 2 can also be regarded as a buffer zone, preventing leakage caused by direct contact between the flowing e-liquid and the atomizer core.

[0030] In this embodiment, the e-liquid in the oil storage chamber 1 is transported to the oil storage cotton 4 in the oil cotton chamber 2 by the fiber rod 5; the oil storage cotton 4 effectively balances the e-liquid received in the atomizing core and the e-liquid evaporated by atomization, avoiding leakage caused by the fluid e-liquid directly contacting the atomizing core, which is convenient and practical.

[0031] Example 2:

[0032] Please see Figure 9As shown, a strip groove 51 extending through both ends is opened along the outer side of the fiber rod 5 along the axial direction. The strip groove 51 forms an air hole between the oil storage chamber 1 and the oil cotton storage chamber 2. The air hole is used for exhaust and can effectively balance the air pressure between the oil storage chamber 1 and the oil cotton storage chamber 2 so that the e-liquid in the oil cotton storage chamber 2 can be smoothly transported to the oil cotton storage 4 through the fiber rod 5.

[0033] Please see Figure 3 As shown, the upper oil cup 11 and the lower oil cup 21 are installed vertically inside the housing 6. The top and adjacent side ends of the housing 6 are open to form an L-shaped opening, making the housing 6 semi-open. The electronic control device 7 is installed below the upper oil cup 11. The electronic control device 7 includes a lithium battery, a display screen, and a charging interface, etc. The electronic control device 7 is existing technology and will not be described in detail again. The lower oil cup 21 and the electronic control device 7 are respectively installed on the left and right sides of the lower part of the housing 6. The semi-open state of the housing 6 facilitates the disassembly, assembly, and maintenance of the upper oil cup 11, the lower oil cup 21, and the electronic control device 7.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
