[0002] In recent years, the e-cigarette market has shown a rapid development trend, with its market size continuing to expand and product types becoming increasingly diverse.

[0003] In existing e-cigarette technology, a light guide strip is typically installed on the side wall of the e-liquid cup to allow users to clearly see the remaining e-liquid level. The working principle is that as the e-liquid surface covers different areas of the light guide strip, it alters the transmission or reflection of light. By observing the areas where the light is blocked or transmitted, users can intuitively and accurately understand the e-liquid level, much like checking a water level gauge.

[0004] However, the current process for assembling the light guide strip onto the oil cup has significant shortcomings. In practice, it often requires manual application of adhesive to the back of the light guide strip before it is attached to the oil cup. This assembly method is highly dependent on manual operation and inefficient; therefore, improvements to the existing technology are necessary. Utility Model Content

A light guide strip is placed on the oil cup, with the connecting post on the side wall of the oil cup passing through it. At this point, the light guide strip is only initially placed and not yet firmly fixed to the oil cup. The telescopic component is activated, and its telescopic end begins to move downwards vertically. Since the heating component is connected to the telescopic end, the movement of the telescopic end drives the heating component downwards as well. As the telescopic end continues to descend, the heating component finally abuts against the connecting post on the side wall of the oil cup. The heating component heats the connecting post, causing it to melt and deform. During the melting process, the connecting post and the light guide strip fully contact and fuse. After the connecting post cools, the light guide strip is firmly fixed to the oil cup. After the light guide strip is fixed, the telescopic end of the telescopic component moves upwards, causing the heating component to leave the connecting post and return to its initial position for the next assembly operation.

[0034] Reference Figures 1-3 According to an embodiment of the present invention, a hot-melt fixture is used to assemble a light guide strip 43 onto an oil cup 42. The side wall of the oil cup 42 is provided with a connecting post 44, which penetrates the light guide strip 43. The connecting post 44 includes:

[0035] The positioning plate 20 is provided with at least one receiving groove 21, which is used to position and fix the oil cup 42.

[0036] The telescopic component, located above the positioning plate 20, includes a fixed end and a telescopic end that can reciprocate in the vertical direction;

[0037] The heating component is connected to the telescopic end. When the telescopic component is activated, it drives the heating component to abut against the connecting column 44. The connecting column 44 is heated and melted to deform and fix the light guide strip 43 to the oil cup 42.

[0038] This invention places an oil cup 42 with a connecting post 44 in the receiving groove 21 of the positioning plate 20. The receiving groove 21 can position and fix the oil cup 42, ensuring that the oil cup 42 is accurately and stably positioned during subsequent operations and will not move or shake. A light guide strip 43 is placed on the oil cup 42, with the connecting post 44 penetrating the side wall of the oil cup 42. At this point, the light guide strip 43 is only initially placed and not yet firmly fixed to the oil cup 42. The telescopic component is activated, and its telescopic end begins to move downwards vertically. Since the heating component is connected to the telescopic end, the movement of the telescopic end causes the heating component to move downwards as well. As the telescopic end continues to descend, the heating component finally abuts against the connecting post 44 on the side wall of the oil cup 42. The heating component heats the connecting post 44, causing it to melt and deform. During the melting process, the connecting post 44 and the light guide strip 43 come into full contact and fuse. After the connecting post 44 cools, the light guide strip 43 is firmly fixed to the oil cup 42. After the light guide strip 43 is fixed, the telescopic end of the telescopic component moves upward, causing the heating component to move away from the connecting post 44 and return to its initial position for the next assembly operation. Compared with the existing process that requires manual gluing, its efficiency is significantly improved.

[0039] According to some embodiments of the present invention, the heating assembly includes a heating plate 30 and a heat-conducting column 32. The heat-conducting column 32 is fixedly disposed on the side of the heating plate 30 facing the positioning plate 20, and the position of the heat-conducting column 32 corresponds to the connecting column 44. When the telescopic component is activated, it drives the heat-conducting column 32 to abut against the connecting column 44. The connecting column 44 is heated and melted to deform so as to fix the light guide strip 43 on the oil cup 42.

[0040] In the initial state, the heating assembly (including the heating plate 30 and the heat-conducting column 32) is separated from the connecting column 44, and the light guide strip 43 is not yet fixed to the oil cup 42. When it is necessary to fix the light guide strip 43 to the oil cup 42, the telescopic component starts to activate. The telescopic component generates a driving force, pushing the heating assembly towards the positioning plate 20, causing the heat-conducting column 32, which is fixed on the side of the heating plate 30 facing the positioning plate 20, to gradually approach the connecting column 44. As the telescopic component continues to push, the heat-conducting column 32 finally comes into close contact with the connecting column 44. At this time, the heating plate 30 starts to work, generating heat. Since the heat-conducting column 32 is fixedly connected to the heating plate 30 and has good thermal conductivity, the heat generated by the heating plate 30 is quickly transferred to the heat-conducting column 32, causing the temperature of the heat-conducting column 32 to rise. After the heat-conducting column 32 comes into contact with the connecting column 44, it transfers heat to the connecting column 44. Under high temperature, the material of the connecting column 44 begins to undergo physical changes and gradually melts, thus forming a tight connection with the light guide strip 43 and the oil cup 42, and firmly fixing the light guide strip 43 to the oil cup 42.

[0041] According to some embodiments of the present invention, the heating assembly further includes a heat insulation plate 33 and at least one heating tube 31; the heat insulation plate 33 is connected to a heating plate 30 and a telescopic end on both sides respectively, and the heating plate 30 is provided with a plug-in groove adapted to the heating tube 31; the heating tube 31 is embedded in the plug-in groove and forms a heat conduction connection with the heating plate 30.

[0042] When heating is required, an external power source supplies power to the heating element 31, which then begins to operate and generate heat. Because the heating element 31 and the heating plate 30 are tightly fitted together via a connector slot, forming a heat conduction connection, the heat generated by the heating element 31 is rapidly transferred to the heating plate 30, causing the temperature of the heating plate 30 to gradually rise. The heat insulation plate 33 serves to insulate against heat, preventing excessive heat generated by the heating plate 30 from being transferred to the telescopic end, thus avoiding damage to the telescopic end due to overheating or affecting its normal operating performance.

[0043] According to some embodiments of the present invention, the positioning plate 20 is provided with a plurality of receiving grooves 21 arranged in a horizontal or vertical array, and the positioning plate 20 is provided with a limiting block 22 on the side facing the heating component. The height of the limiting block 22 is configured such that when the telescopic end drives the heating plate 30 to contact the limiting block 22, the heat-conducting column 32 just presses against the end of the connecting column 44.

[0044] The height of the limiting block 22 is precisely designed to effectively limit the movement distance of the heating plate 30 and prevent the heat-conducting column 32 from applying excessive pressure to the connecting column 44. Without the limiting block 22, the telescopic end may push the heating plate 30 excessively, resulting in excessive pressure from the heat-conducting column 32 on the connecting column 44, which would affect the fixing effect of the light guide strip 43. The presence of the limiting block 22 avoids this situation and protects the safety of all components.

[0045] According to some embodiments of the present invention, the hot melt fixture also includes a base 10, a support column 13 and a top plate 14. The base 10 is used to support the positioning plate 20. The support column 13 is vertically arranged on the base 10, and its top end is fixedly connected to the top plate 14. The top plate 14 is provided with a clearance opening 15. The fixed end is installed on the top plate 14. The telescopic end of the telescopic member passes through the clearance opening 15 and is set towards the positioning plate 20.

[0046] According to some embodiments of the present invention, the hot melt fixture also includes an L-shaped slider 17 and a guide rail 16. The L-shaped slider 17 has a vertical end and a horizontal end that are perpendicular to each other. The guide rail 16 is fixedly disposed on the inner side of the support column 13 in the vertical direction. The vertical end is slidably engaged with the guide rail 16, and the horizontal end is fixedly connected to the heat insulation plate 33 to guide the telescopic end to move in the vertical direction.

[0047] When it is necessary to fix the light guide strip 43, the telescopic component starts to activate, and the telescopic end extends downward from the clearance opening 15 of the top plate 14, pushing the heat insulation plate 33 and the heating plate 30 downward. Because the vertical end of the L-shaped slider 17 slides in conjunction with the guide rail 16, the heat insulation plate 33 and the heating plate 30, guided by the L-shaped slider 17, can only move downward in the vertical direction, ensuring the stability and accuracy of the movement. As the telescopic end continues to push, the heating plate 30 continuously approaches the positioning plate 20. When the heating plate 30 moves to contact the limiting block 22 on the positioning plate 20, the heat-conducting column 32 just presses against the end of the connecting column 44. At this time, the heating tube 31 starts to work, generating heat and transferring it sequentially to the heating plate 30 and the heat-conducting column 32. The heat-conducting column 32 transfers the heat to the connecting column 44, causing the connecting column 44 to melt and deform under heat, thus fixing the light guide strip 43 to the oil cup 42. After the heating and fixing operation is completed, the telescopic component stops working and resets. The telescopic end retracts upward, and the heating plate 30 moves upward through the heat insulation plate 33 and the L-shaped slider 17. The heating plate 30 separates from the limiting block 22 and waits for the next operation.

[0048] According to some embodiments of the present invention, a limiting post 11 is provided above the base 10, and a limiting groove 12 is provided on the lower surface of the positioning plate 20 corresponding to the position of the limiting post 11. The limiting post 11 is limited in the limiting groove 12 to restrict the displacement of the positioning plate 20 in the horizontal direction.

[0049] According to some embodiments of the present invention, the hot melt fixture also includes bolts, the base 10 is provided with through holes, the positioning plate 20 is provided with threaded holes corresponding to the through holes, the bolts pass through the through holes and are threadedly connected to the threaded holes to lock the positioning plate 20 on the base 10.

[0050] When installing the positioning plate 20 onto the base 10, since the base 10 has a limiting post 11 on top and a corresponding limiting groove 12 on the lower surface of the positioning plate 20, the operator places the positioning plate 20 onto the base 10, allowing the limiting post 11 to insert into the limiting groove 12. The cooperation between the limiting post 11 and the limiting groove 12 restricts the horizontal displacement of the positioning plate 20, initially determining the horizontal position of the positioning plate 20 on the base 10 and preventing horizontal offset during installation. After the positioning plate 20 is initially positioned, the through hole on the base 10 aligns with the threaded hole on the positioning plate 20. The operator passes the bolt through the through hole from below the base 10 and rotates the bolt to thread it into the threaded hole on the positioning plate 20. As the bolt is tightened, the positioning plate 20 is securely locked onto the base 10, completing the installation process of the positioning plate 20.

[0051] According to some embodiments of the present invention, the hot melt fixture also includes support feet 18, which are connected to the four corners of the base 10, and the bottom of the support feet 18 is provided with anti-slip texture or anti-slip protrusions.

[0052] During the assembly of the hot melt jig, the support feet 18 are connected to the four corners of the base 10. Then, the hot melt jig is placed on the workbench. Because the bottom of the support feet 18 has anti-slip textures or anti-slip protrusions, the support feet 18 generate a large friction force when in contact with the workbench, so that the hot melt jig can be placed stably on the workbench and will not slide easily.

[0053] According to some embodiments of the present invention, the hot melt fixture also includes a pressure regulating valve 41, and the telescopic component is a cylinder 40, with the pressure regulating valve 41 connected to the air passage of the cylinder 40.

[0054] When heating and fixing operations are required, cylinder 40 begins to operate. Gas from an external source enters cylinder 40 after its pressure is regulated by pressure regulating valve 41, pushing the extension end of cylinder 40 downwards. The extension end moves components such as the heat insulation plate 33 and heating plate 30 downwards, causing the heat-conducting column 32 to press against the connecting column 44. Pressure regulating valve 41 is connected to the gas path of cylinder 40. By changing the opening of pressure regulating valve 41, the gas pressure entering cylinder 40 can be controlled, thereby setting the output force of the extension end of cylinder 40. This ensures that the pressure output by the extension end remains at the set value, thus guaranteeing that the pressure applied by the heat-conducting column 32 to the connecting column 44 is stable and appropriate.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
