Description

Technical Field

[0001] This invention relates to the field of electronic cigarette assembly technology, and in particular to an electronic cigarette assembly method. Background Technology

[0002] In existing technologies, e-cigarettes achieve airflow exchange between the e-liquid reservoir and the external atmosphere through the atomizing air passage in the atomizing component, allowing the e-liquid in the reservoir to be released into the atomizing component during inhalation. However, the e-liquid reservoir and the atomizing air passage remain in a continuous state of communication. Even when the e-cigarette is not inhaled, during transportation and long-term storage and sales, the internal oil pressure in the reservoir can still increase due to temperature rise, causing e-liquid to leak out. This leakage then leads to gas-liquid exchange with the atomizing component through the atomizing air passage, resulting in continuous e-liquid leakage. However, sealing the atomizing air passage is difficult, and e-liquid leakage into the atomizing air passage causes the e-liquid to be exposed to air for a long time, deteriorating and altering the taste of the aerosol when the deteriorated e-liquid is atomized. Summary of the Invention

[0003] The main objective of this invention is to propose an electronic cigarette assembly method to solve the problem of leakage caused by the oil storage tank exchanging gas and liquid with the atomizing component through the liquid guiding channel in existing electronic cigarettes.

[0004] To achieve the above objectives, this application provides an electronic cigarette assembly method, including an atomizing tube, a strip-shaped oil-guiding cotton, a cylindrical atomizing core, an air guide tube with an inner diameter of 0.4-4mm, an oil reservoir, a mouthpiece, and an oil reservoir base; the oil reservoir has an air exchange port and a mouthpiece at the top and an open end at the bottom; the oil reservoir base has an air inlet, and the electronic cigarette assembly method includes: The oil-guiding cotton is wound around the outer peripheral surface of the atomizing core to obtain a first assembly, and the oil-guiding cotton forms a non-closed gap after being wound. An oil inlet is pre-made on the atomizing tube; The first assembly is inserted into the atomizing tube, and the gap is offset from the oil inlet to obtain the second assembly. The second assembly is connected to the oil tank base, so that the air inlet end of the atomizing tube is sealed and inserted into the oil tank base, and the air inlet end of the atomizing tube is connected to the air inlet, thus obtaining the third assembly. Insert the first end of the air guide pipe into the side of the air exchange port located on the inner wall of the oil storage tank to obtain the fourth assembly; The third assembly is connected to the fourth assembly, so that the air outlet end of the atomizing tube is inserted into the inner wall of the oil storage chamber and communicates with the mouthpiece, and the oil tank base is interference-fitted into the opening end of the oil storage chamber, thus obtaining an electronic cigarette in which the atomizing tube, the oil storage chamber, the oil tank base and the air guide tube together form an oil storage cavity, and the second end of the air guide tube is close to the bottom of the oil storage cavity and communicates with the oil storage cavity.

[0005] In some embodiments, the oil tank base is provided with an oil filling hole, and a sealing plug is inserted into the oil filling hole; the assembly method further includes an oil filling step: Before inserting the sealing plug, seal the vent. Use the oil injection device to inject an appropriate amount of e-liquid into the oil storage chamber through the oil injection hole. After the oil injection is completed, insert the sealing plug into the oil injection hole to seal the oil storage chamber.

[0006] In some embodiments, the electronic cigarette further includes a sealing cap having a cap body that seals the mouthpiece and a plug that seals the air vent. Before refilling, the sealing cap is placed on the mouthpiece, while the plug seals the air vent.

[0007] In some embodiments, when the oil-guiding cotton is wound around the outer peripheral surface of the atomizing core, the winding tightness satisfies the following conditions: the outer peripheral surface of the oil-guiding cotton is in contact with the inner wall of the atomizing tube, and the width of the non-closed gap is ≤0.1mm.

[0008] In some embodiments, the oil tank base has a concave surface, the air inlet extends through the oil tank base from the bottom of the concave surface, and after the air inlet end of the atomizing tube is inserted into the air inlet, the axis of the oil inlet is lower than the horizontal plane where the highest point of the concave surface is located.

[0009] In some embodiments, the air duct has a first micropore on the side near the first end. When the posture of the electronic cigarette is adjusted so that the air vent is above the e-liquid, the first micropore is exposed above the e-liquid surface.

[0010] Compared with the prior art, the present invention has obvious advantages and beneficial effects: the components of the electronic cigarette are divided into multiple modules, each module is composed of several interconnected parts, and the modules are assembled and then connected to each other to form a complete electronic cigarette. When e-liquid is injected into the oil storage chamber, there is no need to exchange air through the liquid guide channel between the oil storage chamber and the atomizing component, thus avoiding leakage of e-liquid when exchanging air through the liquid guide channel.

Detailed Implementation

[0013] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. For illustrative purposes, specific structures and details are presented in the description to provide a complete understanding of the embodiments. Those skilled in the art will readily recognize that some features may be omitted in different circumstances, or may be replaced by their components, materials, or methods. In some cases, to make the described embodiments clear, well-known features are not shown or described in the specification; for those skilled in the art, describing these related operations in detail is not necessary.

[0014] refer to Figure 1As shown, this application provides an electronic cigarette, which includes an atomizing tube 3, a strip-shaped oil-guiding cotton 5, a cylindrical atomizing core 6, an air duct 4 with an inner diameter of 0.4-4mm, an oil reservoir 1, a mouthpiece 11, and an oil reservoir base 2; the oil reservoir 1 has an air exchange port 12 and a mouthpiece 11 at the top, and an open end at the bottom. The oil-guiding cotton 5 wraps around the atomizing core 6 and is assembled inside the atomizing tube 3. One end of the atomizing tube 3 is inserted into the oil reservoir base 2 and communicates with the air inlet 22, while the other end of the atomizing tube 3 is connected inside the oil reservoir 1 and communicates with the mouthpiece 11.

[0015] Based on the aforementioned electronic cigarette, this application provides an electronic cigarette assembly method, which includes: Atomizing tube 3 with only one oil inlet 31 is selected, and the hollow pipe of atomizing tube 3 is defined as the atomizing gas path.

[0016] See Figure 1 As shown, the atomizing tube 3 has only one oil inlet 31, so that the e-liquid enters the atomizing tube 3 through the oil inlet 31 and is transferred to the atomizing core 6 by the oil-guiding cotton 5. With only one oil inlet 31, the phenomenon of e-liquid leaking into the atomizing tube 3 due to the oil storage chamber 100 completing gas-liquid exchange with the outside atmosphere through the oil inlet 31 can be reduced.

[0017] Pre-assemble the first assembly: The oil-guiding cotton 5 is wound around the outer peripheral surface of the atomizing core 6 to obtain the first assembly, and the oil-guiding cotton 5 forms a non-closed gap after being wound.

[0018] See Figure 2 As shown, the circumference of the strip-shaped wicking cotton 5 is approximately equal to the circumference of the cylindrical atomizing core 6. However, after the wicking cotton 5 completes the winding action, a gap that cannot be completely closed will be left between the end faces of the two ends. This gap will cause the e-liquid to pass through the gap faster than the e-liquid to pass through the capillary pores of the wicking cotton 5 body when it is immersed from the outside to the inside.

[0019] Pre-installing the second assembly: Insert the first assembly into the atomizing tube 3 and make the gap offset from the oil inlet 31 to obtain the second assembly.

[0020] The wicking cotton 5 needs to be interference-fitted with the atomizing tube 3 to ensure a relatively stable state for the first assembly within the atomizing tube 3. Furthermore, with the gap offset from the inlet 31, the e-liquid, after passing through the inlet 31, can only first wet the wicking cotton 5, and then diffuse outwards from the inlet 31 as the diffusion point until the wicking cotton 5 reaches saturation. The surface tension of the e-liquid forms a liquid seal on the capillary surface of the wicking cotton 5, preventing more e-liquid from overflowing through the wicking cotton 5 under its own weight.

[0021] In some embodiments, when the oil-guiding cotton 5 is wound around the outer peripheral surface of the atomizing core 6, the width of the non-closed gap after winding is ≤0.1mm.

[0022] Pre-assemble the third assembly: Connect the second assembly to the oil tank base 2.

[0023] See Figure 3 As shown, the air inlet end of the atomizing tube 3 is inserted into the oil tank base 2, so that the outer wall of the atomizing tube 3 is sealed to the inner wall of the air inlet 22, and the atomizing tube 3 is connected to the air inlet 22 to obtain the third assembly.

[0024] In some embodiments, the oil tank base 2 is provided with a concave surface 21. Figure 6 As shown, the air inlet 22 extends through the oil tank base 2 from the bottom of the concave surface 21, and the concave surface 21, in conjunction with the air inlet 22, is approximately funnel-shaped. After the air inlet end of the atomizing tube 3 is inserted into the air inlet 22, the axis of the oil inlet 31 is lower than the highest horizontal plane of the concave surface 21.

[0025] Pre-assemble the fourth assembly: connect the air duct 4 to the air exchange port 12.

[0026] See Figure 4 As shown, the air duct 4 has a first end and a second end along the axial direction. The first end is inserted into the air exchange port 12 from the opening end of the oil storage tank 1, so that the outer wall of the first end is sealed with the inner wall of the air exchange port 12 to obtain the fourth assembly.

[0027] Connect the third assembly to the fourth assembly.

[0028] See Figure 5 As shown, the air outlet of the atomizing tube 3 extends into the oil storage chamber 1 from one side of the open end and is inserted into the inner wall of the oil storage chamber 1, so that the air outlet is connected to the outside atmosphere through the mouthpiece 11. At the same time, the oil storage base 2 is interference-fitted into the open end of the oil storage chamber 1, so that the oil storage base 2 seals the open end, resulting in an electronic cigarette in which the oil storage cavity 100 is formed by the atomizing tube 3, the oil storage chamber 1, the oil storage base 2 and the air guide tube 4. The second end of the air guide tube 4 is close to the bottom side of the oil storage cavity 100 and is connected to the oil storage cavity 100.

[0029] In some embodiments, the electronic cigarette assembly method further includes an oil filling step.

[0030] See Figure 6As shown, the oil tank base 2 is provided with an oil filling hole 23, and the oil filling hole 23 is sealed by a sealing plug 7. Specifically, before the oil storage chamber 100 is filled and sealed, the vent 12 is sealed, the oil filling hole 23 faces upward, and an appropriate amount of e-liquid is injected into the oil storage chamber 100 using an oil filling device. After the oil filling is completed, the sealing plug 7 is inserted into the oil filling hole 23 to seal the oil storage chamber 100.

[0031] After the oil filling and sealing of the oil storage chamber 100 is completed, when the oil filling hole 23 is in the downward position, the sealing state of the air exchange port 12 can be released. Since the second end of the air guide tube 4 is below the e-liquid surface, the opening of the second end is sealed by the surface tension of the e-liquid. The external atmospheric pressure and the internal pressure of the oil storage chamber 100 tend to be balanced. Under the action of its own weight, the e-liquid cannot break through the liquid seal, and the difficulty of e-liquid leakage increases.

[0032] In some embodiments, the air duct 4 has a first micropore on the side near the first end face. When the posture of the electronic cigarette is adjusted so that the air exchange port 12 is above the e-liquid, the first micropore is exposed above the e-liquid surface. The electronic cigarette exchanges external air through the first micropore to balance the air pressure in the oil storage chamber 100 with the outside.

[0033] In some embodiments, the air duct 4 has a second micropore on one side near the second end face. When the e-liquid in the oil storage chamber 100 submerges the second micropore, the second micropore is sealed by the surface tension of the e-liquid, and the external atmospheric pressure and the internal pressure of the oil storage chamber 100 tend to be balanced. Under its own weight, the e-liquid cannot break through the liquid seal, and the difficulty of e-liquid leakage increases.

[0034] In some embodiments, the electronic cigarette also includes a magnet 8 for magnetic connection. For example... Figure 6 As shown, the magnet 8 is inserted into the oil filling hole 23 after the sealing plug 7 is inserted into the oil filling hole 23. The magnet 8 can be pressed into the oil filling hole 23 by riveting so that the oil storage chamber 100 can only complete one oil filling. The magnet 8 can also be inserted into the oil filling hole 23 by a detachable plug-in method, pressing against the sealing plug 7, so that the oil storage chamber 100 can be repeatedly filled with oil.

[0035] In some embodiments, the oil injection hole 23 is a countersunk hole. The small diameter section of the countersunk hole is located on the side of the oil tank base 2 near the oil storage cavity 100, and the large diameter section is located on the outside of the oil tank base 2. The large diameter section is connected to the external atmosphere. The sealing plug 7 is sealed with the small diameter section, and the large diameter section is interference-fitted with the magnet 8.

[0036] In some embodiments, the electronic cigarette further includes a sealing cap 9 having a cap body 91 that seals the mouthpiece 11 and a plug 92 that seals the air exchange port 12. Before filling with e-liquid, the sealing cap 9 is placed on the mouthpiece 11, while the plug 92 seals the air exchange port 12.

[0037] The cap body 91 and the plug 92 are integrally formed. For example... Figure 7 , Figure 8 As shown, the cap body 91 has a brim that covers the air vent 12, and the brim protrudes outward to form a plug 92. When the cap body 91 is placed on the suction nozzle 11, the plug 92 can be inserted into the air vent 12 to form a seal. Of course, when the cap body 91 is removed from the suction nozzle 11, the plug 92 also disengages from the air vent 12.

[0038] The above description is only a part or preferred embodiment of the present invention. Neither the text nor the drawings should limit the scope of protection of the present invention. All equivalent structural transformations made using the content of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
