Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic cigarette technology, specifically an electronic cigarette atomizer structure. Background Technology
[0002] The atomizing component is the core part of an electronic cigarette, typically consisting of wicking cotton, a heating mesh, a steel tube, and a tail base. The overall production process is as follows: First, the wicking cotton is used as a base. Then, the heating mesh is placed on the wicking cotton. Next, the center tube is placed on the heating mesh. Then, the wicking cotton is bent along the outer circumference of the shaped tube and finally inserted into the steel tube for fixation. At the same time, the conductive wire is fixed using the tail base. The fiberglass tube and the atomizing component are placed in the integrated cotton, with the fiberglass tube sleeved around the outer circumference of the steel tube. The center tube also needs to be removed during the subsequent assembly process.
[0003] The heating mesh and oil-guiding cotton are not fixed, which can easily cause them to shift, affecting the atomization effect and consequently the taste. In addition, they can also easily cause oil leakage. Utility Model Content
[0004] The purpose of this invention is to provide an electronic cigarette atomizer structure to solve the problems mentioned in the background art.

The atomizing component is placed inside the metal support, and the metal support is provided with oil-absorbing cotton and a rubber plug. The oil-absorbing cotton and the rubber plug are respectively located at the upper and lower ends of the atomizing component.
[0007] The atomizing component is cylindrical and includes an oil-guiding cotton. A mesh body is provided inside the oil-guiding cotton. The mesh body has at least one fixing foot on its upper side and at least two conductive pins on its lower side. The fixing foot is bent and placed on the back of the oil-guiding cotton, and the conductive pins are bent and placed on the back of the oil-guiding cotton. An oil-guiding cloth is also wrapped around the outside of the oil-guiding cotton to cover the fixing foot and conductive pins on the back.
[0008] In a further technical solution, the thickness of the oil-guiding cloth is 0.7mm-1.8mm.

[0013] In a further technical solution, the number of fixing feet is two, arranged symmetrically.
[0014] In a further technical solution, the fixing foot and the conductive pin are staggered.
[0015] The beneficial effects of this utility model are:
[0016] This invention uses absorbent cotton placed between the metal parts to absorb the e-liquid that leaks from the atomizing component, thus preventing the e-liquid from seeping out of the metal bracket. In addition, the use of a rubber stopper instead of the traditional built-in design can effectively save costs.
[0017] This invention uses a fixed foot and a bent conductive pin to fix the position of the oil-guiding cotton and the mesh body, preventing misalignment between the mesh body and the oil-guiding cotton during use, which would affect the atomization effect and user experience.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Please refer to Figure 1-5 ;
[0027] The electronic cigarette atomizer structure described in this utility model provides a fixing structure between the heating mesh and the wicking cotton 11, and solves the problem of oil leakage; specifically, it includes an atomizing component 1 and a metal bracket 2. The atomizing component 1 is placed inside the metal bracket 2. In this embodiment, the atomizer is entirely placed in the integrated cotton during use. E-liquid needs to pass through the bracket to reach the wicking cotton 11 and the heating mesh. Therefore, the side wall of the metal bracket 2 is provided with through holes for e-liquid to pass through. During inhalation, the e-liquid passes through the through holes and is transferred to the wicking cotton 11, and then through the heating mesh. The heating element vaporizes the e-liquid, but the heating element does not vaporize all the e-liquid. The wicking cotton 11 remains moist and stores some e-liquid. After multiple inhalations, a large amount of e-liquid will accumulate in the wicking cotton 11. Moreover, the e-liquid in the wicking cotton 11 rises with each inhalation, which can cause oil leakage at the top. Therefore, in this embodiment, the metal bracket 2 is provided with an oil-absorbing cotton 31 and a rubber plug 32. The oil-absorbing cotton 31 and the rubber plug 32 are located at the upper and lower ends of the atomizing component 1, respectively. The oil-absorbing cotton 31 absorbs the oil that seeps upward and prevents oil leakage.
[0028] Secondly, in the prior art, a metal inner support is set inside the bracket to fix the atomizer. However, in this embodiment, a fixing structure is set between the heating mesh and the oil-absorbing cotton 11, thereby eliminating the inner support and replacing it with a rubber stopper 32. This can also prevent oil leakage and save costs. The oil intake is direct and uniform. Preferably, the oil-absorbing cotton is made of high-density material and has high temperature resistance and oil-blocking effect.
[0029] Further explanation of atomizing component 1;
[0030] The mesh body 12 in this utility model is basically the same as the products on the market. The difference is that the mesh body 12 is provided with at least one fixing foot 13 on the upper side. The fixing foot 13 is usually integrally formed with the mesh body 12. In the initial state, the fixing foot 13 is in an extended state and located on the lower side of the mesh body 12. During assembly, the oil-wicking cotton 11 is laid flat, and then the mesh body 12 is placed on the oil-wicking cotton 11. It should be noted that since this utility model adopts a fixing structure different from the prior art, the area of the oil-wicking cotton 11 used in this embodiment is relatively small. Therefore, the method of cutting the size first and then installing and fixing is adopted, that is, only one cutting is needed, which can save more materials. In contrast, the area of the oil-wicking cotton 11 in the prior art is relatively large. It is cut once in the production process, and then cut again after being assembled with the steel pipe, which wastes more materials. The area of the oil-wicking cotton 11 in the flat state is slightly larger than the area of the mesh body 12.
[0031] Then, the fixing foot 13 is bent 180° and placed on the back of the oil-guiding cotton 11, so that the fixing foot 13 and the mesh body 12 are clamped together, thus clamping and fixing the oil-guiding cotton 11. Preferably, there are two symmetrically arranged fixing feet 13, which can better clamp and fix the oil-guiding cotton 11. This is one of the steps in the production of the atomizing component 1. It can avoid the phenomenon of misalignment between the oil-guiding cotton 11 and the mesh body 12 during subsequent installation steps. The relative position of the oil-guiding cotton 11 and the mesh body 12 is also fixed in a de facto way. The setting of the fixing foot 13 can also fix the relative position of the mesh body 12 and the oil-guiding cotton 11, which can achieve the same fixing effect. It can also remain fixed when subjected to strong vibration, avoiding misalignment between the mesh body 12 and the oil-guiding cotton 11, which would affect the atomization effect and the user experience.
[0032] To further explain, the mesh body 12 should include conductive pins 14. Based on the above-mentioned fixing method, there are two embodiments. In one embodiment, the conductive pins 14 act as fixing feet 13, which are bent 180° and fixed to the back of the oil-wicking cotton 11. In the other embodiment, the fixing feet 13 are independent parts, which are bent 180° and fixed to the back of the oil-wicking cotton 11. The number of conductive pins may change depending on the actual situation, generally two or three, which is not limited here.
[0033] Based on the above-described embodiment of the fixing foot 13, in order to better fix the mesh body 12, it is conceivable to set another fixing foot 13 on the lower side of the mesh body 12. This fixing foot 13 is also bent to the back of the oil-guiding cotton 11, so that there are fixing points on the upper and lower sides of the oil-guiding cotton 11, so as to avoid the oil-guiding cotton 11 and the mesh body 12 from being misaligned due to strong vibration. In this embodiment, the conductive pin 14 is bent to the back of the oil-guiding cotton 11 to achieve double wrapping fixation, which can also achieve the effect of two fixing points. The two bends are equivalent to wrapping the oil-guiding cotton 11 and fixing it firmly to one side of the mesh body 12. No matter how big the impact and vibration, it can remain relatively fixed, without the need to set another fixing foot 13, thus ensuring the atomization quality and taste.
[0034] Preferably, the fixing foot 13 and the conductive pin 14 are staggered, that is, after the fixing foot 13 and the conductive pin 14 are bent, they can both contact the back of the oil-wicking cotton 11, which can better play a fixing role.
[0035] In the above embodiment, the mesh body 12 and the oil-wicking cotton 11 are fixed. However, the shape still needs to be adjusted before it can be installed in the metal bracket 2. Here, a shaping tube is required. In addition, after the bending process, the fixing feet 13 and conductive pins 14 are exposed outside the oil-wicking cotton 11. Therefore, an oil-wicking cloth 15 needs to be wrapped around the outside of the oil-wicking cotton 11 to cover the fixing feet 13 and conductive pins 14 on the back. It should be noted that the thickened oil-wicking cloth 15 can be a single layer or composed of multiple layers stacked together.
[0036] The thickness of the oil-guiding cloth 15 was also crucial after testing. Since a metal bracket 2 is used, if the oil-guiding cloth 15 is too thin, it is easy to be punctured by the fixing foot 13 and exposed to the outside, which may cause a short circuit when it comes into contact with the metal bracket 2. Therefore, the thickness of the oil-guiding cloth 15 used in this embodiment is 0.7mm-1.8mm, which can prevent the fixing foot 13 from being exposed.
[0037] In addition, due to the thickened wicking cloth 15, the wicking cloth 15 has a certain oil storage function, which allows the e-liquid to be introduced more quickly and smoothly during inhalation. Preferably, since the fixing foot 13 and the pin part are placed on the back of the wicking cotton 11, and since the thickened wicking cloth 15 has a slightly worse wrapping effect than the thinner wicking cloth 15, this characteristic is used to create a small gap between the wicking cloth 15 and the wicking cotton 11 after wrapping the wicking cloth 15. The e-liquid can be stored in the small gap, thereby increasing the oil storage capacity.
[0038] In this embodiment of the utility model, the upper end of the metal bracket 2 is provided with an inner step, the upper end of the oil-absorbing cotton 31 abuts against the inner step, the lower end abuts against the upper end of the atomizing component 1, and the rubber stopper 32 abuts against the lower end of the atomizing component 1. The upper and lower abutments can limit the position of the atomizing component 1 and prevent shaking and displacement. In addition, the oil-absorbing cotton can also isolate the pins to prevent short circuits, prevent oil explosion and splashing, and prevent gurgling sounds during the suction process.
[0039] In addition, the metal bracket 2 is inserted into the housing, so at least one sealing ring 21, preferably 2-3, is fitted on the outer side of the upper end of the metal bracket 2. The sealing ring 21 abuts against the inner wall of the housing to form a seal, preventing the e-liquid in the integrated cotton from leaking out.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
