Title: Gas supply device by gasifying burnable liquid

Description:
FIELD OF THE INVENTION  
      The present invention relates to gas supply, and particularly to a gas supply device by gasifying burnable liquid, which agitates and gasifies light oil or solvent oil. The gasified burnable gas is transferred to an external combustion device for providing required fuel used in the combustion device.  
     BACKGROUND OF THE INVENTION  
      In one prior art gas supply device disclosed in Taiwan Patent No. 232366, an oil containing steel bottle has a gas outlet tube and an air inlet tube for inputting compressing air at a top thereof. A lower edge of the air inlet tube extends to a bottom of the steel bottle for guiding compressor air into the oil. Then the air is agitated with the oil. A pump serves for pumping compressed air into the steel bottle. The outlet tube has at least one air transferred rubber tube for guiding burnable gas to a combustor.  
      In above device, no interface active is used. Thereby after a time period, water is mixed in the air to be pumped into the steel bottle so as to mix with the oil in the bottle. The water remains in the bottle so as to affect the combustion. Thereby it is necessary to remove the water in the bottle.  
      Furthermore, larger size oil molecules and oil drops will drain out with the burnable gas so as to affect the combustion of the combustor. In cool whether, since no temperature control device, the air supply is insufficient so that the combustion can not be performed successfully.  
     SUMMARY OF THE INVENTION  
      Accordingly, the primary object of the present invention is to provide a gas supply device by gasifying burnable liquid which comprises a container having a space for filling burnable gas; at least one layer of flow guide plate being arranged in the space; each flow guide plate being arranged with a filter element; a gas generating unit arranged on a container for generating gas and then inputting the container; an input unit arranged on the container for inputting gas from the gas generating unit to the container; a gas divider connected to a tube of the input unit; the gas divider having output holes for generating bubbles; at least one output unit arranged on the container for outputting gas in the container; a pressure sensing unit arranged on the container for sensing pressure within the container; and a constant temperature control unit arranged on the container for sensing temperature within the container for heating at a predetermined timing.

     DETAILED DESCRIPTION OF THE INVENTION  
      In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.  
      With reference to  FIGS. 1 , and  2 , the structure of the present invention is illustrated. The present invention includes a container  1 , a gas generating unit  2 , an input unit  3 , a gas divider  4 , an output unit  5 , a pressure sensing unit  6 , a constant temperature control unit  7 , a pressure releasing unit  8 , and a detector  9 . The container  1  serves to contain burnable liquid. Input gas serves to be agitated with burnable liquid to generate burnable gas for being outputted to an external combustion device.  
      The container  1  has a space  11  for filling burnable gas. At least one layer of flow guide plate  12 ,  13  are arranged in the space. Each flow guide plate  12 ,  13  is arranged with a filter element  14 ,  15 . The filter element  14 ,  15  may be a net for filtering impurity of the gas or larger oil gas or oil drop. Moreover, the flow guide plates  12 ,  13  and filter elements  14 ,  15  serve to prevent burnable liquid from outputting with agitated burnable liquid (oil) in the gasifying process. Besides, the container  1  has an inlet  16  from filling burnable liquid.  
      The gas generating unit  2  is formed by a pump and a power source (for example, a transformer or a battery). The gas generating unit  2  can be arranged on a container  1  or is an external device to be connected to the container  1  for generating gas.  
      The input unit  3  is arranged on the container  1 . The input unit  3  has a check valve switch  31  connected to an output end  21  of the gas generating unit  2  and a tube  32 . The check valve switch  31  serves for preventing input gas from returning back so that the burnable oil flows back. Thereby, the gas supply device can operate successfully.  
      The gas divider  4  has a disk like shape and is connected to the tube  32 . The gas divider  4  has output holes  41  which are arranged as a matrix. The output gas from the tube  32  flows into the gas divider  4  and then is outputted from the output holes  41  for dispersing the gas. Thereby, the gas is effectively mixed or agitated with the burnable liquid.  
      At least one output unit  5  is arranged on the container  1  for outputting gas in the container  1 .  
      The pressure sensing unit  6  is arranged on the container  1 . The pressure sensing unit  6  is an electronic type or an mechanic type for sensing pressure in the container  1 . When the gas from the gas generating unit  2  generates gas which is then inputted to the container  1  to agitate with the burnable liquid. If the pressure sensing unit  6  senses that the internal pressure of the container  1  is sufficient, signals are outputted so that external control circuits stops the operation of the gas generating unit  2 . If the pressure sensing unit  6  is insufficient, signals are outputted to make the external control circuit actuate the gas generating unit  2  for inputting gas to the container  1 .  
      The constant temperature control unit  7  is arranged on the container  1 . The constant temperature control unit  7  contains a temperature sensing element  71  and a heating element  72  for sensing temperature within the container  1  for heating at a predetermined timing. Thereby, the temperature of the container  1  is achieved to a state to gasify. Thereby, it can suit the variations of elevation or weather.  
      The pressure releasing unit  8  is made of a pressure releasing valve so as to be arranged on the container  1 . When the gas supply device is not used, if the internal pressure of the container  1  is increased due to environmental factors, a part of pressure of the container  1  will be released by the pressure relief valve so as to retain a constant pressure of the container  1 .  
      The detector  9  is a window which is arranged on the container  1 . The amount of the burnable liquid in the container  1  is visible for being filled to the container  1 .  
      By above structure, the present invention can be assembled.  
      With reference to  FIG. 3 , a schematic view of the present invention is illustrated. As illustrated in the drawing, the burnable liquid, such as light oil or solvent is added to the container  1 . Then the gas generating unit  2  is actuated for generating gas. Then gas flows through the check valve switch  31  of the input unit  3  and the tube  32  and then to the container  1 . The check valve switch  3   1  serves to prevent the gas flow back so that the burnable oil flows back. Thereby, the gas can be provided successfully. When the gas is transferred to the gas divider  4 , the gas will be dispersed uniformly to the plurality of output holes  41  to generate small bubbles. The bubbles are agitated with the burnable liquid for gasifying. The burnable liquid is gasified completely. After gasifying, the burnable liquid flows through the filter element  14  of the flow guide plate  12 , the filter element  15  of the flow guide plate  13  and then to the output unit  5 . Then, it is outputted by the output unit  5 . Then it is further outputted by an output tube  10  connected to the output unit  5  to the combustion device  101 . In the gasifying process of the burnable liquid, the flow guide plates  12 ,  13  and the filter elements  14 ,  15  serve to prevent larger oil moleculars and oil drops to spout out.  
      The pressure sensing unit  6  sense an internal pressure of the container  1 . In use, when the pressure sensing unit  6  feels that the internal pressure of the container  1  is insufficient. A control signal is outputted to a control circuit to actuate the gas generating unit  2  to operate. When the pressure sensing unit  6  senses that the internal pressure of the container  1  is insufficient, a control signal is outputted to stop the operation of the gas generating unit  2 .  
      When the external combustion device  101  combusts, gas will be drew out. The oil temperature in the device for supplying gasified burnable liquid will descend. After the sensing element  71  of the constant temperature control unit  7  senses the state, a signal is outputted to the heating unit  72  through the control circuit for heating so that temperature of the oil will achieve a predetermined value.  
      When the device for supplying gasified burnable liquid is not used, if the internal pressure of the container  1  increases, the pressure relies unit will adjust to release pressure.  
      Further, the container  1  can be formed by plastic or metal molding. The detector  9  has a window on the container  1  for detecting the liquid amount in the container  1 .  
      Moreover, a cover  102 , see  FIG. 5 , can be arranged on the container  1  for assuring every unit of the container  1  will not be destroyed by external objects.  
      The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
