Gas communication device and gas release method thereof

Abstract

A gas communication device comprises a main body, at least one first pipe, at least one second pipe and at least one sealing member. The first pipe runs straight through the main body, and the first pipe has two ends respectively forming a first opening and a second opening; the second pipe comprises a first end and a second end, the first end being communicated with the first pipe, the second pipe extending from the first pipe out of the main body and forming a third opening at the second end; the at least one sealing member correspondingly seals the second opening of the first pipe. A gas release method using the gas communication device is also disclosed.

1 . A gas communication device, comprising:
 a main body;   at least one first pipe running straight through the main body, the first pipe having two ends respectively forming a first opening and a second opening;   at least one second pipe comprising a first end and a second end, the first end being communicated with the first pipe, the second pipe extending from the first pipe out of the main body and forming a third opening at the second end; and   at least one sealing member for correspondingly sealing the second opening of the first pipe.   
     
     
         2 . The gas communication device of  claim 1 , wherein the first pipe is integrally formed as one-piece. 
     
     
         3 . The gas communication device of  claim 1 , wherein the first pipe has a flow-guiding structure for increasing the flow rate of gas in the first pipe. 
     
     
         4 . The gas communication device of  claim 3 , wherein the flow-guiding structure is a conical structure and the first opening has a cross-sectional area less than that of the second opening. 
     
     
         5 . The gas communication device of  claim 1 , wherein the second pipe and the first pipe are arranged at an included angle ranging from 0° to 180°. 
     
     
         6 . The gas communication device of  claim 5 , wherein the included angle ranges from 90° to 180°. 
     
     
         7 . The gas communication device of  claim 1 , wherein the sealing member is a cover movably connected with the main body. 
     
     
         8 . The gas communication device of  claim 7 , wherein the cover comprises two sliding slots and the main body comprises two protrusions corresponding to the sliding slots. 
     
     
         9 . A gas communication device adapted to switchably provide gas from a gas supplier to a device to be inflated or discharge gas from the device to be inflated using the gas supplier, the gas communication device comprising:
 a main body;   at least one first pipe and at least one second pipe, the first pipe integrally running straight through the main body and having a first opening and a second opening, the second pipe having one end communicated with the first pipe and extending out of the main body; and   at least one sealing member for sealing the second opening of the first pipe when the gas supplier supplies gas from the first opening of the first pipe to the device to be inflated, such that gas enters the device to be inflated through the second pipe;   wherein when the second opening of the first pipe is not sealed by the sealing member, gas from the gas supplier is released from the second opening of the first pipe, thereby creating a pressure difference between the second pipe and the first pipe to facilitate gas release from the device to be inflated.   
     
     
         10 . The gas communication device of  claim 9 , wherein the second pipe and the first pipe are arranged at an included angle to inhibit gas from entering the second pipe. 
     
     
         11 . The gas communication device of  claim 10 , wherein the second pipe is extended away from the second opening. 
     
     
         12 . The gas communication device of  claim 9 , wherein the sealing member is a cover movably connected with the main body. 
     
     
         13 . A gas release method applicable to the gas communication device of  claim 1 , the method comprising: outputting gas from the first opening of the first pipe to the second opening when the second opening is not sealed by the sealing member, thereby creating a pressure difference between the second pipe and the first pipe to facilitate gas release from the device to be inflated through the second pipe and gas discharge via the second opening. 
     
     
         14 . The gas release method of  claim 13 , wherein the gas communication device is used in conjunction with a gas supplier in a separable manner, and wherein the gas communication device is separable from the gas supplier when the gas communication device is disengaged sequentially from two ends. 
     
     
         15 . The gas release method of  claim 14 , wherein the gas supplier comprises at east one connection structure engageable with the gas communication device.
