[0002] The charging spring pin is a kind of precision electronic hardware, which is often used for the transmission connection of current and signals. It is widely used in the charging port of electronic cigarettes.
[0003] The charging port of electronic cigarettes is divided into low current and high current. In order to improve the efficiency of electronic cigarette use, many manufacturers will set the charging port of electronic cigarettes to high current charging when producing electronic cigarettes, which improves the charging efficiency and thus makes it more convenient for people to use electronic cigarettes.
[0004] Therefore, a high-current charging needle is needed to be suitable for current high-current charging electronic cigarette products.
[0005] At present, the existing high-current charging spring needles for electronic cigarettes are generally composed of a needle tube, a needle head, and a spring. However, after long-term use, moisture will exist in the needle tube, which will cause a short circuit in the needle tube of the high-current charging spring needle body, which will directly affect the high-current charging effect. Moreover, the existing high-current charging spring needles for electronic cigarettes are charged with a large current, and the needle head body is small, resulting in a low resistance and weak high-current resistance.
[0006] In addition, the existing high-current charging spring needles used for electronic cigarettes cause overheating inside the needle tube due to high-current charging, and the heat dissipation is low.
[0007] The above problems are widespread and urgently need to be improved. Utility Model Content

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] Reference Figure 1-5 A high-current charging spring needle for electronic cigarettes, comprising a charging spring needle body 1, wherein the charging spring needle body 1 is composed of a needle tube 2, a needle head 3, and a spring 5. A tube cavity 21 is provided in the needle tube 2, and the needle tube 2 is slidably connected with the needle head 3 through the tube cavity 21. An integral coaxial 31 is provided at the right end of the needle head 3, and a heat dissipation groove 4 is provided on the outer wall of the needle tube 2. A heat conductive layer 41 is provided in the heat dissipation groove 4. A hygroscopic drying sleeve 6 is provided on the inner wall of the tube cavity 21, and a dry filling layer 71 is provided in the hygroscopic drying sleeve 6. A hygroscopic hole 61 is provided on the hygroscopic drying sleeve 6. The integral structure of the needle head 3 and the integral coaxial 31 greatly improves the resistance of the needle head 3 itself, and effectively improves the high-current resistance performance of the needle head 3 itself.
[0029] The charging spring pin body 1 is a prior art, and some prior art structures are not drawn and marked, so there is no need to elaborate.
[0030] The spring 5 is sleeved on the integrated coaxial 31, and the two ends of the spring 5 are fixed to the needle 3 and the inner wall of the tube cavity 21 respectively. The spring 5 is made of hard alloy steel, which has high strength, strong elasticity, corrosion resistance and durability, and ensures the guided sliding of the needle 3 and the integrated coaxial 31.
[0031] The heat dissipation grooves 4 are divided into two groups symmetrically, each group has twenty heat dissipation grooves arranged in a circle. The heat dissipation grooves 4 are long open grooves as a whole, which can quickly dissipate the heat transferred from the heat conductive layer 41 to the outside. At the same time, the twenty heat dissipation grooves arranged in a circle can cover the outer wall surface of the needle tube 2, thereby ensuring the effective and comprehensive dissipation of heat.
[0032] The heat-conducting layer 41 is arranged on the inner groove wall of the heat dissipation groove 4. The heat-conducting layer 41 is made of solid heat-conducting silicone material. It is mainly made of organic silicone, with fillers, heat-conducting materials and other polymer materials added, and then mixed to form a solid silicone. It has good thermal conductivity and electrical insulation performance and is durable.
[0033] The hygroscopic drying sleeve 6 is made of aluminum alloy as a whole. A filling cavity 7 is provided inside the hygroscopic drying sleeve 6. The dry filling layer 71 is filled in the filling cavity 7. The hygroscopic drying sleeve 6 made of aluminum alloy is durable and has excellent thermal conductivity. Combined with the copper needle tube 2, heat can be quickly transferred to the heat conductive layer 41.
[0034] The filling cavity 7 is connected to the moisture absorption holes 61 , so that the heat generated in the tube cavity 21 can smoothly and quickly pass through the moisture absorption holes 61 into the filling cavity 7 , thereby achieving moisture absorption and drying of the dried filling layer 71 .
[0035] The dry filling layer 71 is molecular sieve desiccant particles, which are uniformly filled and laid in the filling cavity 7. The molecular sieve desiccant particles have excellent moisture absorption and drying properties, and can effectively absorb and dry the internal moisture of the tube cavity 21, and are durable for long-term use.
[0036] The moisture absorption hole 61 passes through the inner side wall of the moisture absorption and drying sleeve 6, and the inner hole portion of the moisture absorption hole 61 facing the tube cavity 21 is an inward horn diffusion structure, which further increases the effective moisture absorption and drying area of the moisture absorption hole 61 for the moisture inside the tube cavity 21.
[0037] Working method: If moisture appears in the tube cavity 21, the moisture will pass through the moisture absorption hole 61 into the filling cavity 7, and then the moisture will be fully and effectively absorbed and dried by the dry filling layer 71, avoiding the short circuit phenomenon in the needle tube 2 of the charging elastic needle body 1, thereby ensuring the high current charging effect of the charging elastic needle body 1.
[0038] Moreover, when the needle 3 of the charging spring needle body 1 is inserted into the external preset charging port and high-current charging is performed, the overall structure of the needle 3 and the integrated coaxial 31 greatly improves the resistance of the needle 3 itself, and effectively improves the high-current resistance performance of the needle 3 itself.
[0039] In addition, when the needle 3 of the charging pin body 1 is inserted into the external preset charging port and high current charging is performed, a lot of heat will be generated in the tube cavity 21. This heat will be quickly transferred to the heat dissipation groove 4 through the heat conductive layer 41 and then quickly dissipated. The opened heat dissipation groove 4 further increases the effective heat dissipation area of the needle tube 2, thereby improving the heat dissipation of the charging pin body 1 as a whole.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
