Description

Technical Field

[0001] This utility model relates to the technical field of sealing ring elasticity testing equipment, specifically to an elasticity tester for silicone sealing rings in electronic cigarettes. Background Technology

[0002] In the e-cigarette manufacturing industry, silicone sealing rings are a key component ensuring the sealing performance of e-cigarettes. Their quality directly affects whether e-liquid can effectively prevent leakage, thus impacting the overall product performance and user experience. Among the key indicators of quality, the elasticity of the silicone sealing ring is crucial; good elasticity ensures that the sealing ring maintains a reliable seal under various usage scenarios.

[0003] Currently, there are significant shortcomings in testing the elasticity of silicone sealing rings for e-cigarettes. Most existing testing methods can only measure the elasticity of the sealing ring at room temperature, lacking the ability to simulate different temperature conditions. However, e-cigarettes face various temperature environments during actual use. For example, in cold regions or when used outdoors in winter, e-cigarettes operate in a low-temperature environment; while during prolonged continuous use or in high-temperature environments, the internal temperature of the e-cigarette rises significantly. Temperature changes have a significant impact on the elasticity of the silicone sealing ring. In low-temperature environments, the silicone material hardens, reducing its elasticity and potentially leading to decreased sealing performance and an increased risk of e-liquid leakage; while in high-temperature environments, the silicone may soften and, after excessive stretching, struggle to return to its original shape, similarly affecting the sealing effect and shortening the lifespan of the sealing ring.

[0004] Because existing elasticity testing technologies cannot simulate the temperature conditions encountered in real-world use, manufacturers struggle to comprehensively and accurately assess the elasticity performance of silicone sealing rings at different temperatures. This can lead to problems in actual use, such as sealing failure and leakage, due to the sealing ring's inability to adapt to temperature changes. This not only affects the user experience but may also damage the internal electronic components of the e-cigarette, increasing repair costs and return rates. Therefore, developing an instrument capable of simulating different temperature conditions to test the elasticity of silicone sealing rings in e-cigarettes has become a pressing technical challenge for the e-cigarette manufacturing industry.

The technical solution of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0027] Example 1: An elasticity tester for silicone sealing rings in electronic cigarettes includes a tensile drive mechanism 1, a tensile clamp 2 on its right side, and a temperature simulation mechanism 3 on the front side of its right surface. In the tensile drive mechanism 1, a base plate 11 is placed horizontally, and two guide columns 17 are fixed on its top left side. A top beam 14 is fixed at the top of the guide columns 17, and a movable beam 13 is set below the top beam 14. The movable beam 13 can move up and down on the guide columns 17. A circular hole is opened inside the top beam 14, through which a lead screw 16 passes and can rotate. A handwheel 15 is fixed at the top of the lead screw 16. A bearing seat is installed on the left side of the upper surface of the base plate 11, and the bottom end of the lead screw 16 is adapted to rotate with the bearing seat. A fixed nut is embedded in the middle of the movable beam 13, and the nut is adapted to the lead screw 16. A pull rod 12 is fixedly connected to the rear side wall of the movable beam 13. The bottom end of the pull rod 12 is connected to the tensile input end of a tension sensor 18. The bottom surface of the tension sensor 18 is fixed to the top surface of the base plate 11 by bolts. In the tension clamp 2, the upper movable block 21 is fixed to the right end of the movable beam 13, and the lower fixed block 24 is fixed to the right side of the top surface of the base plate 11. Hooks 23 are fixed to the upper movable block 21 and the lower fixed block 24 on opposite sides, and the silicone sealing ring 22 is hooked between the two hooks 23. In the temperature simulation mechanism 3, the bottom surface of the square frame 31 is fixedly connected to the support plate 34, and the bottom end of the support plate 34 is fixedly connected to the right side of the upper surface of the base plate 11. A blower 32 is fixed to the front side of the inner cavity of the square frame 31, and an electric heating wire 33 is fixed to the rear side of the inner cavity. A temperature sensor is installed at the rear port of the square frame 31, and a temperature control knob is installed on the top surface. The rear port of the square frame 31 faces between the upper movable block 21 and the lower fixed block 24. During the test, turning the handwheel 15 causes the lead screw 16 to rotate, which in turn raises the movable beam 13. The upper movable block 21 then rises to stretch the silicone sealing ring 22. The tension sensor 18 records the tension data. At the same time, the blower 32 and the electric heating wire 33 are turned on. The temperature is adjusted by the temperature control knob, and the temperature sensor monitors the temperature, so that hot air is blown onto the stretched silicone sealing ring 22 to simulate the elasticity test under different temperature conditions.

[0028] Example 2: In this electronic cigarette silicone sealing ring elasticity tester, the base plate 11 of the tensile drive mechanism 1 is made of thick steel plate to ensure stability, the guide column 17 is made of high-strength metal, and the top beam 14 and movable beam 13 are also made of sturdy materials. The handwheel 15 has anti-slip texture on its surface for easy rotation by the operator. The upper movable block 21 and lower fixed block 24 of the tensile clamp 2 are made of hard plastic, and the hook 23 is designed to be detachable for easy replacement of silicone sealing rings 22 of different sizes. The square frame 31 of the temperature simulation mechanism 3 is made of heat-insulating material to reduce heat loss, the blower 32 is a low-noise model, and the electric heating wire 33 is designed with uniform distribution to ensure uniform heating. Reinforcing ribs are set at the connection between the support plate 34 and the base plate 11 and the square frame 31 to enhance structural strength. During the test, the silicone sealing ring 22 is first installed on the tension fixture 2. The position of the movable beam 13 is adjusted by the handwheel 15 so that the silicone sealing ring 22 is in a natural state. Then, the temperature simulation mechanism 3 is turned on and the required temperature is set. After the temperature stabilizes, the handwheel 11 is rotated to stretch the silicone sealing ring 22, and the tension sensor 18 records the data in real time.

[0029] Example 3: This electronic cigarette silicone sealing ring elasticity tester features adjustable feet mounted on the bottom of the base plate 11 of the stretching drive mechanism 1, facilitating instrument leveling on different surfaces. A scale line is provided on the movable beam 13, allowing for direct observation of its movement distance and thus understanding the stretching length of the silicone sealing ring 22. Anti-slip textures are provided on the opposing surfaces of the upper movable block 21 and lower fixed block 24 of the stretching clamp 2 to prevent the silicone sealing ring 22 from sliding during stretching. A protective net is installed on the front of the square frame 31 of the temperature simulation mechanism 3 to prevent accidental contact with the blower 32 and heating wire 33 by the operator. The temperature control knob uses a rotary encoder for precise temperature adjustment. During testing, the instrument is first placed in a stable position, the feet are adjusted to level the instrument, the silicone sealing ring 22 is installed, and the temperature simulation mechanism 3 is turned on for preheating. After preheating, the handwheel 15 is slowly rotated to stretch the silicone sealing ring 22, while simultaneously observing the data displayed on the tension sensor 18 and recording the elasticity changes of the silicone sealing ring 22 under different temperatures and stretching degrees.

[0030] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0031] The silicone sealing ring 22 to be tested is hooked between the hooks 23 of the upper movable block 21 and the lower fixed block 24 of the tension clamp 2, so that the silicone sealing ring 22 is in a natural suspension state. The temperature simulation mechanism 3 is turned on, and the required test temperature is set by the temperature control knob. The blower 32 starts to run, blowing air towards the electric heating wire 33. The electric heating wire 33 heats the air, and the heated air is blown out from the rear port of the square frame 31. Since the rear port of the square frame 31 faces the upper movable block 21 and the lower fixed block 24 close to each other, the hot air blows directly onto the stretched silicone sealing ring 22. The temperature sensor monitors the hot air temperature in real time and feeds back the data. The operator can fine-tune the temperature to the set value by using the temperature control knob according to the feedback. After the temperature stabilizes at the set value, the operator rotates handwheel 15. Handwheel 15 drives lead screw 16 to rotate within the circular hole of top beam 14. Since the nut inside movable beam 13 is compatible with lead screw 16, the rotation of lead screw 16 causes movable beam 13 to move upward along guide post 17. Movable beam 13 drives upper movable block 21 to rise. Upper movable block 21 stretches silicone sealing ring 22 through hook 23. Simultaneously, pull rod 12 on the rear side of movable beam 13 transmits the tension to tension sensor 18. Tension sensor 18 records the tension data of silicone sealing ring 22 in real time during the stretching process. During the stretching process, the operator can continuously rotate handwheel 15 to increase the stretching degree as needed, observe the changes in data recorded by tension sensor 18, and record the elastic performance of silicone sealing ring 22 at the set temperature under different stretching degrees. After the test is completed, stop rotating handwheel 15, turn off the power of temperature simulation mechanism 3, and after silicone sealing ring 22 cools down, remove it from hook 23 and tidy up the components of the testing instrument for the next test.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
