Detailed Description

The present invention will be further described with reference to the following examples for facilitating understanding of those skilled in the art, and the description of the embodiments is not intended to limit the present invention.

Fig. 1 to 3 show a first embodiment of a one-way self-closing communicator according to the present invention, which includes a female housing assembly and a male connector body 1 corresponding to the female housing assembly, wherein the female housing assembly includes a female housing 2, a gas adding chamber 21 opened in the female housing 2, a communication hole 22 located in an inner wall of the gas adding chamber 21, and a sealing cover 3 located in an inner wall of the gas adding chamber 21 for sealing the communication hole 22, the male connector body 1 is provided with a male connector tube 11 detachably and hermetically connected to the communication hole 22, and when the male connector tube 11 is completely inserted into the communication hole 22 and hermetically connected, the sealing cover 3 is pushed open by the male connector tube 11 to generate a gap before the communication hole 22.

When the male pipe 11 is inserted into the communication hole 22, the sealing cover 3 is jacked up by the end part of the male pipe 11, and due to the existence of the interval, the gas in the gas adding chamber 21 can smoothly enter the male pipe 11 to realize the functions of communication and gas filling; when public first pipe 11 is pulled out, sealed lid 3 under the effect of atmospheric pressure or elastic component fast with the drill way butt of intercommunicating pore 22 and stifled intercommunicating pore 22 to realized the self-closing function of intercommunicating vessel, only need insert or pull out public first pipe 11 can in the use, need not any other operation, had simple structure, response speed is fast and the accurate advantage that targets in place of break-make, the practicality is strong.

In this embodiment, add built-in the elastic component that is equipped with and is used for making sealed lid 3 to butt intercommunicating pore 22 all the time of air chamber 21, it is specific, the elastic component is spring 31, when public first pipe 11 was extracted, utilizes the elastic component can further realize the stifled effect of dying of intercommunicating pore 22 fast, and the gas tightness is better, and sealed effect is better.

In this embodiment, the end surface of the male pipe 11 is provided with the air inlet notch groove 12, and when the end surface of the male pipe 11 abuts against the sealing cover 3, the air inlet notch groove 12 is designed to further increase the ventilation flow rate between the male pipe 11 and the communication hole 22, thereby improving the inflation efficiency.

In this embodiment, female seat casing 2 is connected with flexible glue seal block 23 in a sealing manner, this flexible glue seal block 23 is seted up to intercommunicating pore 22, and after public first pipe 11 inserted intercommunicating pore 22, the design of flexible glue seal block 23 can effectively improve the leakproofness between the outer wall of public first pipe 11 and the inner wall of intercommunicating pore 22.

In this embodiment, a sealing rubber ring 31 is disposed on a side surface of the sealing cover 3, and when the sealing cover 3 blocks the communication hole 22, the sealing rubber ring 31 abuts against an end surface of the communication hole 22. The sealing rubber ring 31 is designed to further improve the air tightness between the sealing cover and the communicating hole 22 during sealing, and the reliability is higher.

In this embodiment, the number of the communication holes 22 is more than two, and the two or more communication holes 22 are both communicated with the air charging chamber 21 so as to be conveniently connected with a plurality of health care devices in a ventilation manner, so that the multifunctional air charging device has multiple purposes, strong practicability and high cost performance.

In this embodiment, the female housing 2 is provided with an air inlet pipe joint 24 communicated with the air charging chamber 21, so that a hose connected to an air pump is conveniently communicated with the air charging chamber 21, and the assembly is convenient.
