PRIORITY CLAIM 
       [0001]    This application claims the benefit of China Patent Application No. 201520807285.X filed on Oct. 19, 2015. The contents of the foregoing application are incorporated by reference in their entirety as if fully set forth herein. 
       FIELD OF THE INVENTION 
       [0002]    The present invention relates to a breathing mask and a gas providing device, and more particularly, the present invention relates to the breathing mask and the gas providing device, which can allow user to breath in specified gas smoothly. 
       DESCRIPTION OF THE PRIOR ART 
       [0003]    Breathing system is one of the several kinds supporting system for maintaining the patient&#39;s life in the hospital. A breathing mask is usually used to provide a high concentration of oxygen or cleaning air for patients. It can also be used to let respiratory failure patients breathe in the needed oxygen normally. In common, a breathing system includes a breathing mask and a gas tube. The gas tube connects the breathing mask and a gas generator, so that the oxygen or air generated by the gas generator can be entered to the breathing mask. The breathing mask can fit the patient&#39;s nose and mouth in order to provide high concentration of oxygen or air to the patients. The breathing system can also be connected to other medical gas or anesthetic gas generators for providing medical or anesthetic proposes. 
         [0004]    Except for medical purpose, the breathing system can also be used for other purposes, such as providing the air in emergency or daily care. It can be achieved for any purposes of inhaling gas by nose or mouth when using the breathing system. 
         [0005]    For example, the gas generator can generate hydrogen or oxygen for providing the medical gas sources. A free radical is produced by the oxidation of metabolism. It has one or many non-pairs of electrons or ions, which can attract the nearby electrons because of its active property. Furthermore, the free radical is created for maintaining the human body&#39;s functions by generating good chemical matters or resisting the diseases, such as generating enzymes and engulfing diseases by leukocytes. In addition to the reasons mentioned above, the free radical can be generated by outside environment such as smoke, drinking, radiation, UV, and electromagnetic wave, etc. According to current research, the free radical is the major cause of chronic diseases, cancers, and ageing. 
         [0006]    Free radicals can be exhausted from the human body by composing the hydrogen to H2O. Hydrogen is a strong reduction of antioxidant. Furthermore, hydrogen can reduce free radicals from human body, which returns the acidity to alkalinity physique to achieve the effects of anti-oxidation, anti-ageing, the elimination of chronic diseases, and health care. Much research shows that the patient who has lung injury due to breathing high concentration of oxygen can be relieved by breathing hydrogen. 
         [0007]    In the prior art, the device that can generate hydrogen or a mixture of hydrogen and oxygen is used as a common device for health protection. In general, the hydrogen or the mixture of hydrogen and oxygen which generated by a gas generator can enter a breathing mask through a gas inputting tube. The user wears the breathing mask to breathe in the hydrogen or the mixture of hydrogen and oxygen. The breathing mask is fitted to the user&#39;s face, and it can cover the nose, even the mouth. However, the user not only inhales the gas but also exhales the waste gas. The breathing mask is half-airtight to cover the nose so that the waste gas remains inside the breathing mask and blends with the hydrogen or the mixture of hydrogen and oxygen generated by the gas generator. Accordingly, it reduces the efficiency of the gas generator when the waste gas reacts with the mixture of hydrogen and oxygen and then becomes useless gas. 
         [0008]    Therefore, it is necessary to develop a breathing mask to prevent the waste gas exhaled by users from interfering with the healthy gas which is supposed to be inhaled by users.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0025]    A detailed description of the hereinafter described embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures. Although certain embodiments are shown and described in detail, it should be understood that various changes and modifications may be made without departing from the scope of the appended claims. The scope of the present invention will in no way be limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc., and are disclosed simply as an example of embodiments of the present invention. 
         [0026]    The present invention provides a breathing mask  1 . Please refer to  FIG. 1A  and  FIG. 1B .  FIG. 1A  is a schematic diagram of the breathing mask  1  according to an embodiment of the invention.  FIG. 1B  is a schematic diagram of side view for the breathing mask  1  according to  FIG. 1A . The breathing mask  1  comprises a main body  10 , a gas inputting tube  12 , a one-way valve  16 , and at least one gas existing tube  14 . The main body  10  has a containing part  100  and a fitting part  102 . The containing space  1000  is formed by a central hollow of the containing part  100 , and the fitting part  102  is connected to an outer edge of the containing part  100 . In fact, when user uses the breathing mask  1 , the main body  10  is worn and let the fitting part  102  fit to the user&#39;s face. Then the nose, even the mouth is contained in the containing space  1000 . Besides the main body of the breathing mask further comprises a headband which is disposed to the fitting part or the containing part so as to fix the main body of the breathing mask to the user&#39;s face. The gas inputting tube  12  is connected the central of the containing part  100  of the main body. In more detail, the gas inputting tube  12  is connected to another side of the containing space  1000  of the containing part  100 . 
         [0027]    The gas inputting tube  12  is connected between the containing part  100  and the gas generator. In fact, the gas generator is a device which can provide any kinds of medical or health care gas such as oxygen, hydrogen, mixture of hydrogen and oxygen, or any devices for providing anesthesia gas. The generated gas can be entered to containing space  1000  of containing part  100  from the gas inputting tube  12 , and breathed by users from containing space  1000 . Containing space  1000  forms an airtight space because the containing part  100  and the fitting part  102  fit the user&#39;s face, which can avoid the outside gas interfering with the generated gas from the gas generator. 
         [0028]    The one-way valve  16  is disposed between the gas inputting tube  12  and the containing part  100 . The one-way valve  16  can let the gas pass through in only one direction. The one-way valve  16  can make the gas generated by gas generator enter into the containing space  1000  for the user&#39;s breathing. Contrarily, the waste gas which the user exhales is blocked by the one-way valve  16  so that the waste gas cannot be entered into the gas inputting tube  12  from the containing space  1000 . 
         [0029]    The gas existing tube  14  is connected to the other side of containing space  1000  of containing part  100 , and connected to the containing space  1000  which is located on the other side of containing part  100 . As mentioned before, although the containing part  100  and the fitting part  102  can block most of the outside gas from entering into the containing space  1000 , the waste gas can interfere with the gas which is exhaled by the user himself/herself in the containing space  1000 . However, due to the one-way valve  16 , the waste gas that the user exhales doesn&#39;t enter into the gas inputting tube  14  from containing space  1000 . The waste gas can be entered into the gas exiting tube  14  from the containing space  1000  and be exhausted to the outside as well. In more detail, the waste gas that the user exhales is passed to the containing space  1000  to the outside through the gas exiting tube  14 , so that the interference with the gas generated by the gas generator is reduced. 
         [0030]    In fact, the gas exiting tube  14  can be various types to exhaust the waste gas and keep the generated gas from the gas generator. For example, as shown in  FIG. 1A , the gas exiting tube  14  connects and extends to the bottom of the main body  10 . The waste gas (no matter exhaled from the nose or the mouth) can be exhausted directly by the gas exiting tube  14  because the nostril direction and the mouth position are below to the gas exiting tube  14 . In the other hand, the waste gas is carbon dioxide which is much heavier than oxygen, hydrogen, and air. The gas exiting tube  14  is positioned to the bottom of the main body  10  and extends downward, which can help the waste gas sink spontaneously. 
         [0031]    According to an embodiment of the invention, there are two gas exiting tube  14 , and they connect to the both sides of the lower part of the main body  10  so as to correspond to the nose position. However, there is not limited to two gas exiting tube  14 . At least one gas exiting tube can achieve the waste gas exhausting effect. Moreover, a plurality of through holes  140  are formed on the gas exiting tube  14  for exhausting the waste gas effectively from the containing space  1000 . 
         [0032]    According to an embodiment of the invention, the breathing mask can provide the needed gas to the user without the interference of the outside gas. And, since the waste gas that users exhale themselves is blocked by the one-way valve, the waste gas cannot be entered into the gas inputting tube but be exhausted from the gas exiting tube. Accordingly, the gas exiting tube doesn&#39;t affect the generated gas from gas generator. Moreover, the gas exiting tube can increase the efficacy of the user&#39;s gas breathing. 
         [0033]    In addition, when a user wears the breathing mask, he/she can keep various postures, such as lying on the bed or sitting on the chair. For users&#39; comfort and the adaptation of the breathing mask, the gas inputting tube is rotatably connected to the containing part in order to fit the user&#39;s nose under different postures. 
         [0034]    Please refer to  FIG. 2 .  FIG. 2  is a schematic diagram of the gas providing device  2  according to an embodiment of the invention. As  FIG. 2  shown, the gas providing device  2  comprises a gas generator  20  and a breathing mask  22 . The gas generator  20  can generate the gas for users&#39; breathing, such as hydrogen, oxygen, mixture hydrogen and oxygen, or anesthesia gas, etc. The breathing mask  22  comprises a main body  220 , a gas inputting tube  222 , a one-way valve  226 , and at least one gas existing tube  224 . The main body  220  has a containing part  2200  and a fitting part  2202 . The gas inputting tube  222  is connected the central of the containing part  2200  and the gas generator  20 , which provide the generated gas from gas generator  20  to the containing space of containing part  2200 . The one-way valve  226  is disposed between the gas inputting tube  222  and the containing part  2200 . The one-way valve  226  can let the gas pass through from gas generator  20  to the containing part  2200  in one direction. Also, at least one gas exiting tube  224  connects to the containing part  2200 . There is substantially the same about the elements of the breathing mask  22  according to an embodiment of the invention; for example, a plurality of through holes are formed on the gas exiting tube  224 , the containing space is formed by a central hollow of the containing part  2200 , the fitting part  2202  is connected to an outer edge of the containing part  2200 , etc. 
         [0035]    When a user uses the gas providing device  2 , the breathing mask  22  is worn on the face so that the containing part  2200  can cover the user&#39;s nose. In fact, the breathing mask  22  further comprises a headband so as to fix the breathing mask  22  to the user&#39;s face. However, any kinds of stuff that can fix the breathing mask to the user&#39;s face are reasonably chosen to use. 
         [0036]    The gas generator  20  is started when a user is ready to wear the breathing mask  22 . The generated gas from the gas generator  20  can be breathed by the user from gas generator  20 , which is passed through from gas inputting tube  222  to the containing space of the containing part  2200 . Due to the one-way valve  226 , the waste gas that users exhale doesn&#39;t enter into the gas inputting tube  224  from the containing space. The waste gas is entered to the gas exiting tube  114  from the containing space and is exhausted to the outside. According to an embodiment of the invention, the breathing mask  22  can provide the generated gas by gas generator  20  to the user without the interference of the outside gas. Accordingly, the gas exiting tube doesn&#39;t affect the generated gas from gas generator. Moreover, the gas providing device can increase the efficacy of the user&#39;s gas breathing. 
         [0037]    Please refer to  FIG. 3 ;  FIG. 3  is a schematic diagram of the gas providing device according to another embodiment of the invention. As  FIG. 3  shown, the gas providing device  3  further comprises a vaporized gas generator  34 . The gas providing device  3  is connected to a containing part  3200  through a gas inputting tube  322 . The vaporized gas generator  34  can vaporize the gas and enters into the containing part  3200  through the gas inputting tube  322 . In detail, the vaporized gas generated by the vaporized gas generator  34  is mixed with the generated gas (ex: hydrogen or mixture of hydrogen and oxygen) by the gas generator, and then is entered to the containing part  3200 . Both effects of the vaporized gas and the hydrogen can be obtained by breathing these two gases. Please note that the other elements of the gas providing device  3  are substantially similar to the gas providing device  2 . 
         [0038]    According to an embodiment of the invention, the vaporized gas and the mixture of hydrogen and oxygen are mixed before entering the gas inputting tube  322 . However, the vaporized gas and the mixture of hydrogen and oxygen can be separated to enter to the containing space. For example, the vaporized gas and the mixture of hydrogen and oxygen can be entered into the first gas inputting tube and the second gas inputting tube respectively. Then the two gases are mixed when entering to the containing space. 
         [0039]    According to an embodiment of the invention, the breathing mask of gas providing device can provide the needed gas to the user without the interference of the outside gas. And the waste gas cannot be entered into the gas inputting tube and can be exhausted from the gas exiting tube. Moreover, the gas exiting tube can increase the efficacy of the users&#39; gas breathing. 
         [0040]    With the examples and explanations mentioned above, the features and spirits of the invention are hopefully well described. More importantly, the present invention is not limited to the embodiment described herein. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the meets and bounds of the appended claims.
