Description

Technical Field

[0001] This utility model relates to the field of alcohol lamp technology, and in particular to a novel alcohol lamp. Background Technology

[0002] An alcohol lamp is a commonly used open-flame heating tool in laboratories. It consists of a glass bulb, a cotton wick, and a metal cap. The bulb is filled with alcohol, ideally with the volume controlled between 1 / 3 and 2 / 3. The fuel is delivered through capillary action of the wick. When in use, the wick is lit. The outer flame temperature can reach 400-600℃, which is the effective heating area. Its simple structure and convenient operation make it widely used in low-temperature heating scenarios such as chemical experiments, biological cultivation, and teaching demonstrations.

[0003] Traditional alcohol lamps with manual capping pose significant safety hazards: during operation, the hand must be close to the high-temperature flame, which can easily cause burns; if the extinguishing action is unstable or the bottle opening is not completely covered, residual sparks may ignite alcohol vapors, causing a risk of reignition or explosion. To address these issues, we propose a new type of alcohol lamp. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a new type of alcohol lamp.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel alcohol lamp, comprising a lamp bottle, an oil cylinder, a closing cap, a bottle mouth, a plug rod, and a connecting rope. The lamp bottle has a bottle mouth at its upper end, and a wick located inside the bottle mouth. A symmetrically distributed support is provided at the upper end of the lamp bottle, and a rotating shaft is rotatably installed inside the support. A central block is provided at the center of the rotating shaft, and a closing cap is provided at one end of the central block. A torsion spring is sleeved on the outside of the rotating shaft, with its two ends connected to the closing cap and the central block, respectively. An oil cylinder is provided at one end of the lamp bottle, and a sealing ring is embedded in the opening at the upper end of the oil cylinder. A piston is slidably installed inside the oil cylinder, and oil holes arranged in a circular array are opened inside the piston. A second spring is provided between the piston and the lower inner wall of the oil cylinder. A connecting rope is slidably installed inside the sealing ring and connected to the closing cap at its upper end.

[0006] In existing designs, a sealing gasket is provided at the upper end of the closed cap, and a collar is fitted onto the outer wall of the oil cylinder. One end of the collar has a positioning hole, and a connecting block is provided on one side of the lower end of the closed cap. A retaining pin, with one end located inside the positioning hole, is inserted into the connecting block. The sealing gasket improves the seal when the closed cap is in contact with the bottle opening, and the retaining pin, after being slidably supported by the connecting block, has one end located inside the positioning hole, thus securing the closed cap after rotation.

[0007] In existing designs, one end of the insertion rod is equipped with a pull handle, and a limiting ring is sleeved on the outer wall of the retaining shaft. A spring is sleeved on the outside of the retaining shaft between the limiting ring and the connecting block. Gripping the pull handle facilitates applying a pulling force to the retaining shaft, and the limiting ring is elastically supported by the spring, allowing the retaining shaft to be positioned inside the positioning hole.

[0008] In existing systems, the inner wall of the bottle opening is provided with a conical baffle, and the baffle has liquid holes arranged in a circular array that communicate with the inside of the bottle. The baffle isolates the lamp bottle from the bottle opening, and the liquid holes allow alcohol splashed onto the wick and intercepted by the bottle opening to flow back.

[0009] In the existing design, a rod is slidably installed inside the liquid outlet. A sealing plug, inserted into the lower inner wall of the liquid outlet, is fitted onto the outer wall of the rod. A limiting ring is fitted onto the outer wall of the rod, and a spring is connected to the lower end of the partition. When the cap is closed over the bottle opening, the rod is pushed down, causing the sealing plug to move out of the lower opening of the liquid outlet, allowing the alcohol at the upper end of the partition to flow back. When the cap is opened, the elastic force of the spring compresses the sealing plug into the liquid outlet, preventing alcohol from flowing out through the liquid outlet during use.

[0010] In existing designs, one end of the lamp bottle is connected to a feeding port, and a sealing plug is installed inside the upper end of the feeding port. A pull rope is installed at the upper end of the sealing plug. The feeding port is used to add alcohol, and the opening and closing of the feeding port is controlled by the sealing plug. The sealing plug can be easily pulled up by gripping the pull rope.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a rotating, closing cap at the opening of an alcohol lamp. The cap is elastically supported by a torsion spring and is positioned by a snap-fit ​​mechanism after opening. When the flame is extinguished, the cap engages its locking mechanism, causing it to automatically flip and close the bottle opening. During the flipping process, a piston slides inside the oil cylinder. The hydraulic oil's resistance to the piston's stroke ensures a slow and gentle closure, preventing significant impact on the bottle opening. This design is faster than traditional manual operation while reducing the impact force and preventing damage to the glass bottle opening. The entire process requires no physical contact with the open flame, significantly improving inherent safety. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5 As shown, this utility model proposes a novel alcohol lamp, including a lamp bottle 1, an oil cylinder 3, a closing cap 4, a bottle mouth 6, a plug rod 14, and a connecting rope 25. The upper end of the lamp bottle 1 is provided with a bottle mouth 6, and the lamp bottle 1 is provided with a wick 5 located inside the bottle mouth 6. The upper end of the lamp bottle 1 is provided with symmetrically distributed brackets 2, and a rotating shaft 13 is rotatably installed inside the brackets 2. A central block 12 is provided at the center of the rotating shaft 13, and a closing cap 4 is provided at one end of the central block 12. A torsion spring 11 is sleeved on the outside of the rotating shaft 13, with its two ends connected to the closing cap 4 and the central block 12 respectively. The lamp bottle 1 is provided with an oil cylinder 3 at one end, and a sealing ring 24 is embedded in the upper opening of the oil cylinder 3. A piston 26 is slidably installed inside the oil cylinder 3, and oil holes 27 are distributed in a ring array inside the piston 26. A spring 28 is provided between the piston 26 and the lower inner wall of the oil cylinder 3. A connecting rope 25 is slidably installed inside the sealing ring 24 and connected to the closing cap 4 at the upper end of the piston 26.

[0021] A sealing gasket 10 is provided at the upper end of the closed cover 4, and a collar 22 is sleeved on the outer wall of the oil cylinder 3. A positioning hole 23 is opened inside one end of the collar 22. A connecting block 17 is provided on one side of the lower end of the closed cover 4. A retaining pin 18 with one end located inside the positioning hole 23 is inserted into the connecting block 17.

[0022] One end of the insertion rod 14 is provided with a pull handle 19, and a limit ring 21 is sleeved on the outer wall of the locking shaft 18. A spring 20 is sleeved on the outside of the locking shaft 18 between the limit ring 21 and the connecting block 17.

[0023] The inner wall of the bottle mouth 6 is provided with a conical baffle 15, and the baffle 15 has liquid holes 16 arranged in a ring array and communicating with the inside of the bottle body.

[0024] A rod 14 is slidably installed inside the liquid hole 16. A sealing plug 31 is sleeved on the outer wall of the rod 14 and inserted into the inner wall of the lower end of the liquid hole 16. A limiting ring 29 is sleeved on the outer wall of the rod 14. A spring 30 is connected to the lower end of the partition plate 15 via the limiting ring 29.

[0025] One end of the lamp bottle 1 is connected to a material inlet 9. A closing plug 7 is provided inside the upper end of the material inlet 9, and a pull rope 8 is provided at the upper end of the closing plug 7.

[0026] Based on the implementation steps of Example 1: Under the elastic potential energy of the torsion spring 11, the closed cap 4 flips upward around the rotating shaft 13. The user pulls the handle 19 outward with one hand, causing the locking shaft 18 to be inserted into the positioning hole 23 inside the collar 22, locking the closed cap 4. At this time, the connecting rope 25 is mostly located inside the oil cylinder 3 through the elastically supported spring 28. After the wick 5 is lit, it is used for experimental operation. When the flame needs to be extinguished, the locking shaft 18 moves out of the positioning hole 23. Under the support of the torsional elasticity of the torsion spring 11, the closed cap 4 rotates around the rotating shaft 13 to close the bottle mouth 6. At the same time, through the connecting... Rope 25 pulls piston 26 upward in oil cylinder 3. Under the action of gravity and spring 28, piston 26 slides to the bottom of oil cylinder 3. Hydraulic oil generates a throttling effect through oil hole 27 of piston 26, forming a damping force to slowly close the closing cap 4. Finally, the sealing gasket 10 is completely attached to the conical surface of bottle mouth 6 to achieve an airtight seal. The closing plug 7 at the feed port 9 is lifted by pulling rope 8. Alcohol is injected into lamp bottle 1 through feed port 9 to the recommended liquid level of 1 / 3-2 / 3. The structure of partition 15 can effectively intercept alcohol droplets that may splash during the combustion of lamp wick 5, and achieve liquid backflow through liquid hole 16 to prevent fuel waste.

[0027] The automatic closing mechanism driven by the torsion spring 11 completely eliminates the operational risks of manually capping the glass bottle by requiring the user to approach the flame. The hydraulic damping system reduces the closing impact force, preventing cracks in the glass bottle opening 6 due to violent collisions and significantly extending the service life of the equipment. The sealing gasket 10 of the closing cap 4 forms a line contact seal with the conical surface of the bottle opening 6. In conjunction with the sealing plug 31 driven by the insertion rod 14, the liquid hole 16 is dynamically opened and closed. In the extinguished state, the sealing plug 31 contacts the blockage of the liquid hole 16, allowing the alcohol to flow back. In the working state, the closing cap 4 squeezes the insertion rod 14 to open the sealing plug 31. The insertion rod 14 is released from the compression of the closing cap 4, causing the sealing plug 31 to close the liquid hole 16, eliminating the risk of burns caused by manual capping. The damping closing mechanism avoids the risk of glass breakage, making it particularly suitable for experimental teaching scenarios for teenagers.
