Description

Technical Field

[0001] The utility model relates to a heating device for a laboratory, in particular to an alcohol combustion device. Background Art

[0002] Human beings have a very close relationship with chemical industry, which is popularized in all aspects of life. Some chemical products play an epoch-making and important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. Alcohol lamp is the most basic experimental instrument in chemical laboratories. Alcohol lamp is a heating tool that uses alcohol as fuel. It is widely used in laboratories, factories, medical treatment and scientific research. Since it does not produce smoke during the combustion process, it can also achieve the purpose of sterilization by burning the equipment. Because the heat generated by the alcohol lamp during the combustion process can heat other experimental materials, its heating temperature reaches 400-1000℃.

[0003] In some experiments, a sterile environment is required, so most of them need to be carried out in a clean bench. The clean bench is a relatively closed environment. When an alcohol lamp is used in it, some volatile or incompletely burned alcohol will gradually escape. When it accumulates to a certain concentration, it may be ignited, causing a fire and causing danger. Utility Model Content

[0004] In view of the problem that alcohol lamps may cause danger due to alcohol escape in relatively closed environments such as clean benches, the utility model provides an alcohol combustion device, which can introduce the upper air of the relatively closed space into the alcohol lamp, burn and consume the escaped alcohol, reduce the alcohol concentration in the closed space, and improve the safety of alcohol lamps in these environments.

[0005] In order to achieve the above object, the utility model provides an alcohol combustion device, which comprises:

[0006] Alcohol lamp, including:

[0007] Bottle,

[0008] The wick holder with a hole is arranged on the bottle body and has a hollow pipe inside.

[0009] The wick is arranged in the wick holder with holes,

[0010] The alcohol filling port is arranged on the bottle body.

[0011] An air inlet is provided on the bottle body;

[0012] The air capture cover is funnel-shaped and communicates with the air inlet.

[0013] Preferably, the bottle body is separated into a wick bin and an alcohol bin by a partition, and the partition is provided with a through hole adapted to the wick at a position above 2 / 3 of the height from the bottom, so that the wick can extend from the wick bin to the alcohol bin, and the through hole is located above the alcohol liquid level;

[0014] The alcohol filling port is located on the alcohol bin, and the air inlet is located on the wick bin.

[0015] Preferably, the bottle body is provided with a handle.

[0016] Furthermore, the bottle body is a metal bottle body, and the handle is a hollow, transparent handle.

[0017] Preferably, the wick is a cotton wick.

[0018] Furthermore, a Tesla valve is provided in the alcohol filling port.

[0019] Preferably, a magnet is provided at the cover opening of the air capture cover.

[0020] The air capture cover is placed on the air introduction port, or is connected thereto through a hose.

[0021] Through the above technical solution, the utility model achieves the following beneficial effects:

[0022] 1. The utility model utilizes an air capture hood to capture flowing air. With the funnel effect, the flow rate of the captured air is accelerated. The air enters the bottle body and is introduced into the flame of the alcohol lamp from the hollow pipe. On the one hand, the volatile or incompletely burned alcohol is fully utilized to burn and consume the escaped alcohol, thereby reducing the alcohol concentration in the confined space and improving the safety of the alcohol lamp in these environments. On the other hand, sufficient air is introduced into the inner flame of the flame to avoid the disadvantage that the outer flame of the ordinary flame burns fully but the inner flame burns insufficiently.

[0023] 2. In a preferred technical solution of the utility model, the bottle body is separated into a wick compartment and an alcohol compartment by a partition. The partition prevents a large amount of alcohol in the alcohol compartment from entering the wick compartment, thereby avoiding the possibility of a fire caused by alcohol quickly flowing to the wick holder after the alcohol lamp is overturned, thereby ensuring the safety of laboratory equipment and personnel.

[0024] 3. In another preferred technical solution of the present invention, a magnet is provided at the cover opening of the air capture cover, and the air capture cover only needs to be adsorbed on the top of the clean bench, which is simple and convenient to install.

[0025] 4. In another preferred technical solution of the present invention, a Tesla valve is provided in the alcohol filling port to prevent leakage of alcohol or alcohol vapor.

[0026] 5. In another preferred technical solution of the utility model, the bottle body is made of metal to improve safety, and the handle is a hollow, transparent handle. The principle of communicating vessels can be used to display the alcohol content inside the alcohol lamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0031] First of all, it should be noted that in the following description, some directional words, such as "outside" and "inside", etc., are used to clearly explain the technical solution of the utility model. They are all analogous to the normal directions of the parts in the alcohol combustion device. For example, the accommodating cavity of the bottle body is the inside, and the part opposite to it is the outside. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the utility model.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 As shown, the alcohol combustion device described in the utility model includes:

[0034] Alcohol lamp, including:

[0035] Bottle 1,

[0036] The wick holder 2 with a hole is arranged on the bottle body 1 and has a hollow pipe 21 inside.

[0037] The wick 3 is arranged in the wick holder 2 with a hole.

[0038] The alcohol filling port 4 is provided on the bottle body 1.

[0039] An air inlet 5 is provided on the bottle body 1;

[0040] The air capture cover 6 is funnel-shaped and communicates with the air inlet 5 .

[0041] The utility model can be used in a clean bench or other relatively closed environment. When in use, the air capture hood 6 is connected to the air inlet 5, and the flowing air is captured by the wind direction of the clean bench. A filter can be added to the air outlet of the clean bench to filter the air to ensure the cleanliness of the air. If it is other occasions where the internal air is not flowing, a motor fan needs to be installed in the closed space to blow the air in the direction of the air capture hood 6. As the funnel effect accelerates the flow rate of the captured air, the air enters the bottle body 1 and is introduced into the flame of the alcohol lamp from the hollow pipe 21. On the one hand, the volatile or incompletely burned alcohol is fully utilized to burn and consume the escaped alcohol, thereby reducing the alcohol concentration in the closed space and improving the safety of the alcohol lamp in these environments; on the other hand, a sufficient amount of air is introduced into the inner flame of the flame to avoid the disadvantages of the outer flame of the ordinary flame being fully burned and the inner flame being insufficiently burned.

[0042] The air capture cover 6 can be directly placed on the air inlet 5, or can be connected thereto through a hose.

[0043] The wick of a traditional alcohol lamp is placed directly in alcohol. If the alcohol lamp is knocked over, the alcohol will quickly flow to the wick holder, accelerating the combustion and possibly causing a fire, which is unsafe. Therefore, in the utility model, the bottle body 1 is separated into a wick bin 12 and an alcohol bin 13 by a partition 11. The bottle body 1 is separated into a wick bin 12 and an alcohol bin 13 by a partition 11. The partition 11 is provided with a through hole adapted to the wick 3 at a position above 2 / 3 of the height from the bottom, so that the wick 3 can extend from the wick bin 12 to the alcohol bin 13, and the through hole is located above the alcohol liquid level; the alcohol filling port 4 is located on the alcohol bin 13, and the air inlet 5 is located on the wick bin 12. The partition 11 prevents a large amount of alcohol in the alcohol bin 13 from entering the wick bin 12, thereby avoiding the possibility of a fire caused by alcohol quickly flowing to the wick holder after the alcohol lamp is knocked over, and ensuring the safety of laboratory equipment and personnel. In addition, the alcohol content in the bottle body 1 usually does not exceed 2 / 3 of the volume. The through hole is arranged at a position above 2 / 3 of the height of the partition 11 from the bottom, that is, the through hole is located above the alcohol liquid level, thereby preventing alcohol from entering the wick compartment 12 through the through hole and affecting the separation effect.

[0044] In order to facilitate the installation of the air capture cover 6, a magnet is provided at the cover opening, so that the air capture cover 6 only needs to be adsorbed on the top of the clean bench, and the installation is simple and convenient.

[0045] In addition, in order to prevent alcohol from spilling out of the alcohol filling port 4 and causing a fire after the alcohol lamp is knocked over, a Tesla valve 41 is provided in the alcohol filling port 4. The Tesla valve 41 is used to smoothly introduce air to prevent alcohol or alcohol vapor from leaking out.

[0046] In order to facilitate the gripping and moving of the alcohol lamp, a handle 7 is provided on the bottle body 1.

[0047] Traditionally, glass alcohol lamps are widely used, which are easy to explode and very dangerous, so the bottle body 1 is made of metal, but the metal material is opaque, and the amount of alcohol in the alcohol lamp cannot be observed. Each time the alcohol is added, it is easy to overflow, and the user does not know the amount of alcohol remaining in the alcohol lamp. Therefore, the handle 7 is set as a hollow, transparent handle. The handle 7 can be made of thickened glass, hollow, and can be used to display the alcohol content inside the alcohol lamp using the principle of a communicating vessel.

[0048] The wick 3 is usually a cotton wick.

[0049] 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, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0051] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
