Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laboratory containers, in particular to an alcohol lamp for a laboratory. Background Art
[0002] The alcohol lamp is a heating tool that uses alcohol as fuel. It consists of an alcohol lamp body, a porcelain wick and a lamp cap. The heating temperature of the alcohol lamp is 400-500℃, which is suitable for experiments that do not require too high a temperature, especially when there is no gas equipment.
[0003] At present, the alcohol lamp body will be radiated by the heat of the wick. After the alcohol lamp is extinguished with a lamp cap, the cooling of the alcohol lamp body will cause negative pressure to form between the lamp cap and the alcohol lamp body, making it difficult to remove the lamp cap. In addition, the wick of the alcohol lamp used in the laboratory cannot adjust the flame size. The adaptation effect in different heating operations is achieved by changing the distance between the heated object and the outer flame of the alcohol lamp, and the flame utilization rate is low. In addition, the alcohol lamp is fragile after being knocked over. The ignited alcohol lamp will cause a large-scale alcohol combustion after being smashed, which poses a safety hazard. Utility Model Content
[0004] Purpose of the utility model: to provide an alcohol lamp for laboratory use to solve the above-mentioned problems existing in the prior art.
[0005] Technical solution: A laboratory alcohol lamp includes an alcohol lamp body, a heat-insulating cap, a porcelain wick and a wick rope, wherein the wick rope is arranged inside the porcelain wick, and the heat-insulating cap is arranged between the alcohol lamp body and the porcelain wick to prevent the heat of the wick rope from burning from being transferred to the alcohol lamp body.
[0006] Furthermore, the alcohol lamp body has a double-layer structure, and a cooling cavity is formed inside the alcohol lamp body.
[0007] Furthermore, the cooling cavity is filled with a flame retardant.
[0008] Furthermore, the bottom thickness of the alcohol lamp body is greater than the wall thickness.
[0009] Furthermore, heat-insulating asbestos is provided between the heat-insulating cap and the alcohol lamp body.
[0010] Furthermore, a fire control cover is sleeved on the wick rope, and the fire control cover is a conical tube structure. The fire control cover is arranged on the porcelain wick to cover the wick rope exposed outside the alcohol lamp body.
[0011] Furthermore, the alcohol lamp also includes a lamp cap, which is arranged on the heat insulation cap.
[0012] Furthermore, a float is provided inside the alcohol lamp body to indicate the alcohol remaining inside the alcohol lamp body.
[0013] Beneficial effects: The utility model adds a heat-insulating cap between the alcohol lamp body and the porcelain wick, which effectively blocks the heat from the burning wick from being transferred to the alcohol lamp body, and avoids the formation of negative pressure between the lamp cap and the alcohol lamp body when the alcohol lamp body cools down after the lamp cap covers the wick, thus solving the problem that the lamp cap is difficult to remove. In addition, the flame control cover can effectively change the effective burning length of the wick, thus achieving the purpose of changing the size of the flame. In addition, the double-layer alcohol lamp body is filled with flame retardant in the cooling cavity, which effectively inhibits the burning of a large area of alcohol after the alcohol lamp is overturned. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 It is a schematic diagram of the internal structure of the utility model.
[0016] The accompanying drawings are marked as follows: 1. alcohol lamp body; 2. insulation cap; 3. porcelain wick; 4. flame control cover; 5. wick rope; 6. buoy; 7. insulation asbestos; 8. cooling chamber. DETAILED DESCRIPTION
[0017] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.
[0018] like Figure 1-Figure 2 As shown, a laboratory alcohol lamp includes an alcohol lamp body 1, an insulating cap 2, a porcelain wick 3 and a wick rope 5, wherein the wick rope 5 is arranged in the porcelain wick 3, and the insulating cap 2 is arranged between the alcohol lamp body 1 and the porcelain wick 3, so as to prevent the heat of the wick rope 5 from being transferred to the alcohol lamp body 1 when burning.
[0019] The utility model adds a heat insulating cap 2 between the alcohol lamp body 1 and the porcelain wick 3, which effectively blocks the heat of the wick rope 5 from being transmitted to the alcohol lamp body 1 when it burns, avoids the formation of negative pressure between the lamp cap and the alcohol lamp body 1 when the alcohol lamp body 1 is cooled after the lamp cap covers the wick rope 5, and solves the problem that the lamp cap is difficult to remove.
[0020] The alcohol lamp body 1 has a double-layer structure, and a cooling cavity 8 is formed inside the alcohol lamp body 1. The cooling cavity 8 is filled with a flame retardant. The cooling cavity 8 provides a storage space for the flame retardant. When the alcohol lamp body 1 is knocked over, when the outer layer of the double-layer alcohol lamp body 1 is broken, the alcohol inside will not be scattered over a large area, and will not cause a large-scale alcohol combustion. Even if the inner layer of the alcohol lamp body 1 is also broken, the flame retardant will be scattered first at the falling position, which has a flame retardant effect on the alcohol, and effectively improves the use safety of the alcohol lamp.
[0021] Specifically, the bottom thickness of the alcohol lamp body 1 is greater than the wall thickness. The thicker bottom of the alcohol lamp body 1 can make the placement stability of the alcohol lamp body 1 better and not easily knocked over. The bottleneck opening of the alcohol lamp body 1 is large, and the large-diameter alcohol lamp body 1 reduces the manufacturing difficulty of the double-layer structure.
[0022] A heat insulating asbestos 7 is provided between the heat insulating cap 2 and the alcohol lamp body 1. The heat insulating asbestos 7 can block heat diffusion on the one hand, and can compensate for the assembly gap between the heat insulating cap 2 and the alcohol lamp body 1 on the other hand.
[0023] The wick rope 5 is covered with a flame control cover 4, which is a conical tube structure, and is arranged on the porcelain wick 3 to cover the wick rope 5 exposed outside the alcohol lamp body 1. The flame control cover 4 can be set to a variety of sizes, and the flame control covers 4 of various sizes can effectively change the effective burning length of the wick rope 5, thereby achieving the purpose of changing the flame size, and the flame size can be selected according to the conditions of the heated object.
[0024] A float 6 is provided inside the alcohol lamp body 1 to indicate the alcohol remaining inside the alcohol lamp body 1. The double-layer structure and flame retardant design of the alcohol lamp body 1 increase the difficulty for the user to judge the alcohol remaining, and the addition of the float 6 can help the user quickly judge the alcohol remaining.
[0025] The alcohol lamp also includes a lamp cap, which is arranged on the heat-insulating cap 2. Specifically, the lamp cap is placed on the cone wall of the heat-insulating cap 2, and the contact between the cone wall and the lamp cap is not easy to fit, which is not conducive to the lamp cap and the heat-insulating cap 2 forming a closed space.
[0026] When the utility model is used, the porcelain wick 3 can be removed from the heat-insulating cap 2, and then the buoy 6 can be put into the alcohol lamp body 1, and an appropriate amount of alcohol can be poured. Then the porcelain wick 3 is placed on the heat-insulating cap 2. Before lighting the alcohol lamp, a suitable fire control cover 4 can be selected according to the heated object, and the fire control cover 4 can be put on the wick rope 5. Because the fire control cover 4 limits the effective burning length of the wick rope 5, the size of the flame can be controlled. After the alcohol lamp is used, the wick rope 5 is extinguished with the lamp cap. Under the blocking effect of the heat-insulating cap 2 on the heat source energy and the difficult adhesion between the cone wall of the heat-insulating cap 2 and the lamp cap, the lamp cap will not be adsorbed on the heat-insulating cap 2.
[0027] If you accidentally touch the alcohol lamp body 1, the bottom of the alcohol lamp body 1 is stable, and a slight collision will not overturn the alcohol lamp body 1. If the alcohol lamp body 1 is overturned to the ground, the outer layer of the alcohol lamp body 1 is broken, and the flame retardant is first spilled. Even if the inner layer of the alcohol lamp body 1 is broken, the alcohol will spill on the flame retardant. It is difficult to cause a large-scale alcohol combustion even if the alcohol lamp is overturned, and the use safety is relatively good.
[0028] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
