Description

Technical Field

[0001] The present invention relates to the field of electronic cigarettes, and in particular to an anti-leakage structure of a liquid oil electronic cigarette. Background Art

[0002] With the rapid development of the e-cigarette market, liquid oil e-cigarettes have gradually become an important alternative for smokers to traditional cigarettes due to their portability and diverse flavors. However, liquid oil e-cigarettes currently on the market generally have oil leakage problems, which not only affects the user experience, but may also cause equipment damage and environmental pollution.

[0003] Existing solutions to prevent oil leakage mainly include reducing the diameter of the oil inlet hole, reducing the number of oil inlet holes, and adding silicone plugs and metal rods to seal the inside of the airway when shipping.

[0004] However, these methods have many disadvantages. First, adding a sealing device will significantly increase production costs; second, users need to remove the silicone plug and metal rod by themselves before use, which increases the difficulty of operation; in addition, these methods are difficult to completely eliminate oil leakage, resulting in an increase in the defective product rate.

[0005] In addition, the existing structure is difficult to effectively prevent oil leakage during long-term transportation and static storage, further affecting the product's market competitiveness and user satisfaction. Summary of the invention

[0006] In order to solve the above problems, the present invention provides an anti-leakage structure for liquid oil electronic cigarettes, which adds a closing / opening structure at the front end where the oil enters the atomization chamber, and uses the assembly transmission mechanism of the cigarette rod and the cigarette cartridge to realize the automatic closing and opening of the oil inlet hole, thereby effectively preventing oil leakage when the cigarette cartridge is separated from the cigarette rod, and ensuring that the device remains sealed during transportation and static storage. This structure not only effectively solves the oil leakage problem in the prior art, but also optimizes the production cost and operation convenience, providing strong support for the further development of liquid oil electronic cigarettes.

DETAILED DESCRIPTION

[0034] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0035] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0036] like Figure 1-Figure 6As shown, an anti-leakage structure of a liquid oil electronic cigarette of the present invention includes a cartridge assembly 100 and a cigarette rod assembly 200, and the cartridge assembly 100 and the cigarette rod assembly 200 are assembled using a disassembly structure, which is convenient for user operation. An atomization bin for accommodating tobacco oil is provided inside the cartridge assembly 100, and an oil inlet hole 22 is provided at the input end of the atomization bin for realizing the transmission of tobacco oil from the storage area to the atomization area. In order to solve the oil leakage problem of liquid oil electronic cigarettes, the present invention designs a closed-open structure, which is installed on the outside of the atomization bin, and realizes the closing and opening of the oil inlet hole 22 by linkage with the assembly relationship of the cartridge assembly 100 and the cigarette rod assembly 200. When the cartridge assembly 100 is separated from the cigarette rod assembly 200, the closed-open structure can automatically close the oil inlet hole 22; when the cartridge assembly 100 and the cigarette rod assembly 200 are assembled together, the closed-open structure makes the oil inlet hole 22 conductive, thereby ensuring the normal supply of tobacco oil.

[0037] The closed-open structure includes an outer steel tube bracket 8 mounted outside the atomization chamber, and the oil inlet hole 22 is arranged on the steel tube bracket, so that the oil inlet hole 22 is fixed and supported by the steel tube bracket. At the same time, the movable bracket 10 is movably mounted outside the outer steel tube bracket 8, and the movable bracket 10 has at least two movable extension rods 11, and the movable extension rods 11 can be extended into the bottom cover of the bottom of the cigarette cartridge assembly 100 to achieve cooperation with other components.

[0038] The bottom end of the movable bracket 10 is provided with a sealing silicone ring 9, which wraps the outer steel pipe bracket 8 and is used to provide a reliable sealing effect when the oil inlet hole 22 is closed. A sealing silicone gland 12 is installed at the bottom of the sealing silicone ring 9, and the sealing silicone ring 9 is fastened to the bottom of the movable bracket 10 through the sealing silicone gland 12, thereby further enhancing the sealing performance in the closed state.

[0039] A positioning sleeve 16 is provided at a position corresponding to the movable extension rod 11 in the bottom cover of the cigarette cartridge assembly 100, and a pin plug 13 is installed in the positioning sleeve 16. The movable extension rod 11 can extend into the positioning sleeve 16 and cooperate with the pin plug 13. One end of the pin plug 13 is fixedly installed in the movable extension rod 11, and the other end corresponds to the position of the cigarette rod assembly 200.

[0040] When the cigarette cartridge assembly 100 is assembled with the cigarette rod assembly 200, the positioning rod 6 provided on the cigarette rod assembly 200 is inserted into the positioning assembly sleeve 16, and the pin plug 13, the movable extension rod 11, the movable bracket 10, the sealing silicone ring 9 and the sealing silicone gland 12 are pushed, so that the originally sealed oil inlet hole 22 is opened, and the inflow of the smoke oil is completed. The liquid inlet path 19 is as shown in FIG. Figure 4 As shown, the liquid is introduced by utilizing the gap formed in the middle and the siphon principle.

[0041] Furthermore, the sealing silicone ring 9 is designed to have two sealing parts, including a first sealing part 21 and a second sealing part 20, and a gap sealing interval is formed between the two. When the cigarette cartridge assembly 100 is separated from the cigarette rod assembly 200, the oil inlet hole 22 is in the gap sealing interval, ensuring that the oil inlet hole 22 remains in a good sealing state even during long-term storage or transportation to prevent oil leakage.

[0042] In order to enhance the reset capability of the closed-open structure, the pin plug 13 is fixedly connected to the movable extension rod 11, and a spring 14 is installed outside the pin plug 13. One end of the spring 14 is in contact with the bottom surface of the positioning assembly sleeve 16 for support, and the other end is in contact with the pin plug 13 for support. When the pin plug 13 is compressed, the spring 14 is compressed; when the assembly relationship is released, the elastic force of the spring 14 pushes the pin plug 13 to reset, driving the movable extension rod 11 and the sealing structure to return to the closed state.

[0043] In addition, the movable extension rod 11 passes through a cigarette cartridge movable silicone member 17 at the inner end of the bottom cover, and the cigarette cartridge movable silicone member 17 is provided with a silicone sealing convex portion 18 at the position where the movable extension rod 11 passes through, which is used to always maintain the sealing of the movable extension rod 11 during the activity process. An interference fit is adopted between the silicone sealing convex portion 18 and the movable extension rod 11, thereby ensuring that the movement of the movable extension rod 11 will not destroy the sealing effect, and the sealing can be ensured even when there is excessive traction.

[0044] The bottom of the shell 7 of the cartridge assembly 100 is designed as a bottom cover, on which a plurality of first magnetic blocks 3 are arranged, and the cigarette rod assembly 200 is correspondingly provided with a second magnetic block 5, and the first magnetic block 3 and the second magnetic block 5 are magnetically acted upon to ensure reliable assembly of the cartridge assembly 100 and the cigarette rod assembly 200. In addition, a pin hole 2 is also provided on the bottom cover, and a conductive pin 4 is provided at a position corresponding to the pin hole 2 on the cigarette rod assembly 200. When the cartridge assembly 100 and the cigarette rod assembly 200 are assembled, the conductive pin 4 is inserted into the pin hole 2 to complete the circuit connection, thereby providing power support for the normal operation of the atomization chamber.

[0045] The bottom opening of the positioning and assembly sleeve 16 forms a socket 15, and the positioning rod 6 is inserted into the positioning and assembly sleeve 16 from the socket 15, and cooperates with the pin plug 13. The overall structural design is compact, and through the combination of the linkage mechanism and the sealing device, the automatic closing and opening function of the oil inlet 22 of the liquid oil electronic cigarette before and after use is realized, further improving the reliability of preventing oil leakage, and at the same time, the operation is convenient, and the user can use it directly without additional disassembly of the closure.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
