Description

FIELD OF THE INVENTION

[0001] The present invention related to fuel container device, and more particularly to a safety device for containing fuel.

BACKGROUND OF THE INVENTION

[0002] In general, liquefied petroleum gas is produced as a byproduct from the oil and gas extraction and refining process. Liquefied petroleum gas, i.e., natural gas, is a kind of hydrocarbons mainly comprising propane, butane as its component.

[0003] Since petroleum gas, at normal atmospheric temperature, is existing in form as a gas, so the volume thereof is huge and thus the way to deliver it causes some inconvenience. In order to make the transportation easy, the petroleum gas is generally subjected to be formed as in phase of liquid by applying pressure or lowering temperature. Moreover, petroleum gas, which is lighter than water, insoluble to water, and colorless and odorless, is deemed dangerous and is easily to be neglected to its danger, due to the reason that its component of propane and butane is highly combustible. For this consideration, petroleum gas was added with mercaptan and ether or other ingredients to generate a stimulating smell of pungent for the safety in process of transportation and storage, so that users could detect whether the leakage is happening.

[0004] Nevertheless, there is still a lot of news reporting that accident about the gas explosion, mostly due to the bad quality of the fuel container, or the negligence of flammable and explosive characteristics of the fuel gas. Therefore, it is an important issue to maintain the combustion efficiency of the fuel gas and reduce the possibility of explosion as well.

SUMMARY OF THE INVENTION

[0005] Therefore, an object of the present invention is to provide a safety device for containing fuel. The safety device for containing fuel comprises a container having a fuel containing space. A fuel tube is provided within the fuel containing space. The fuel tube is hallow tube-shaped and has a top connection orifice and a bottom connection orifice. The top connection orifice and the bottom connection orifice is connected with each other. The bottom connection orifice is connected to the fuel containing space. A fuel supplying tube provided within the container and is connected with the top connection orifice, wherein a upper transmitting opening is formed in a wall of the fuel tube at a position below the top connection orifice. A lower transmitting opening is formed in a wall of the fuel tube at a position above the bottom connection orifice; wherein the fuel containing space contains fuel mixture which is essentially mixed by a gas fuel and petroleum ether, and wherein the fuel mixture flows through the fuel tube and the fuel supplying tube, and the flow of the fuel mixture is maintained stable by the regulation of the upper transmitting opening and lower transmitting opening.

[0006] According to the present invention, wherein weight ratio between the gas fuel and the petroleum ether is 17:3.

[0007] According to the present invention, wherein the gas fuel is liquefied petroleum gas.

[0008] The present invention provides a safety device for containing fuel by providing the upper transmitting opening and the lower transmitting opening in the fuel tube to enhance the mixture of the phase of liquid and gas while the gas fuel flows through these openings, and to further allow the mixture fuel flowing back to the fuel containing space via the fuel tube. Thus, the possibility of gas explosion is reduced and the safety effect for the usage of fuel is enhanced.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The structure and the technical means applied by the present invention for achieving the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings.

[0010] Fig. 1 is a schematic cross-section view illustrating an embodiment of safety fuel member according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The detailed description of the invention which follows is made with reference to the drawings and in terms of a preferred embodiment of the invention. The detailed description is not intended to limit the scope of the present invention, and the only limitations intended are those embodied in the claims hereto.

[0012] Please refer to Fig. 1, which is a schematic view illustrating an embodiment of the present invention. A safety fuel member 100 according to the present invention includes a container 1, a valve 2 connecting the container 1, and a fuel tube 3.

[0013] A container 1, that is a fuel cylinder, has a fuel containing space 10 for fuel storage. The container 1 is connected to a fuel supplying tube 11. The fuel supplying tube 11 is provided with an end thereof extending to the outside of the container 1 and the other end thereof extending to the fuel containing space 10. The fuel is outputted to the external portion of the fuel containing space 10 or injected to the inside of the fuel containing space 10 through the fuel supplying tube 11.

[0014] A fuel mixture F essentially consisting of the gas fuel and petroleum ether storage is contained in the fuel containing space 10. Preferably, a weight ratio between gas fuels and petroleum ether is 17:3. That is, in the case of the weight of gas fuels is 17 kilograms in the fuel containing space 10, the weight of petroleum ether is 3 kilograms in the fuel containing space 10. Gas fuel that is liquefied petroleum gas is consisted of propane and butane. The petroleum ether is a lightweight petroleum products, containing 5 to 6 carbon atoms in the alkane mixture (a mixture of pentane and hexane), mostly as a solvent. The sinking butane of the mixed fuel which mixed with the gas fuel and petroleum ether is dissolved more completely by petroleum ether. The nature of the fuel mixture F leads stably by mixed uniformly.

[0015] The valve 2 is connected fuel supplying tube 11 in order to control the fuel mixture F flowing in the fuel supplying tube 11.

[0016] The fuel tube 3 is installed in the fuel containing space 10. A seaming 12, which is connected to the one end of the fuel supplying tube 11, is formed at the container 1. The fuel tube 3 is connected to the fuel supplying tube 11 through the seaming 12 and the fuel mixture F flows in the fuel supplying tube 11 through the fuel tube 3.

[0017] Specifically, the fuel tube 3 is a hallow tube having a top connection orifice 31 and a bottom connection orifice 32. A connecting part 33 is formed at a predetermined distance below the top connection orifice 31. In this embodiment, the connecting part 33, which is a screwed connecting portion, is connected to the seaming 12 of the container 1. In this way, the top connection orifice 31 of the fuel tube 3 is connected to the fuel supplying tube 11 of the container 1. The bottom connection orifice 32 which is located in the other end of the fuel tube 3 and connects to the fuel containing space 10 nears the bottom of the container 1. Thus, fuel mixture F in the fuel containing space 10 flows in the fuel tube 3 through the bottom connection orifice 32, then the fuel mixture F flows in the fuel supplying tube 11 through the top connection orifice 31 and exports to the exterior, such as table top cooking appliances, through the fuel supplying tube 11.

[0018] In addition, an upper transmitting opening 34 is formed in a wall of the fuel tube 3 at a position below the top connection orifice 31, a lower transmitting opening 35 is formed in a wall of the fuel tube 3 at a position above the bottom connection orifice 32. The upper transmitting hole 34 is used for making the fuel mixture F through the fuel tube 3 to be mixed with the flammable gas within the fuel containing space 10 in full. Then the fuel mixture F is released from the fuel supplying tube 11 through the valve 2. The lower transmitting hole 35 is used for transmitting the refluxing fuel mixture F to the bottom of the fuel containing space 10. In detail, when the level of fuel mixture F is below the lower transmitting hole 35, the pressure of flammable gas is decreased within the fuel containing space 10. Thus the fuel mixture F flowing into the fuel tube 3 refluxes to the bottom of the fuel containing space 10 through the lower transmitting hole 35. In this way, the pressure of the safety fuel member 100 is regulated and the nature of the fuel mixture F and flammable gases is stable by mixed uniformly to lower the possibility of gas explosions and oil leakages.

[0019] The above description should be considered as only the discussion of the preferred embodiments of the present invention. However, a person skilled in the art may make various modifications to the present invention. Those modifications still fall within the spirit and scope defined by the appended claims.
