One-way self-closing communicating vessel

Abstract

The invention relates to the technical field of health physiotherapy equipment, in particular to a one-way self-closing communicating vessel. The communicating vessel comprises a female seat assemblyand a male connector body. The female seat assembly comprises a female seat shell, an air-entrapping chamber formed in the female seat shell, a communicating hole and a sealing cover; the male connector body is provided with a male connector pipe which is detachably connected with the communicating hole in a sealed mode; when the male connector pipe is completely inserted into the communicating hole and is connected with the communicating hole in a sealed mode, the sealing cover is jacked by the male connector pipe to be separated from the communicating hole. When the male connector pipe is inserted into the communicating hole, the sealing cover is jacked up by the end of the male connector pipe, and due to the existence of the interval, the gas in the gas filling chamber can smoothly enter the male connector pipe to achieve the communicating gas filling function. When the male connector pipe is pulled out, the sealing cover rapidly abuts against the hole opening of the communicating hole under the action of air pressure or an elastic piece and blocks the communicating hole, so the automatic closing function of the communicating vessel is achieved, and only the male connector pipeneeds to be inserted or pulled out; the communicating vessel has the advantages of being simple in structure, high in response speed and accurate in on-off in place.

Description

technical field [0001] The invention relates to the technical field of health physiotherapy equipment, in particular to a one-way self-closing connector. Background technique [0002] With the growth of age and long-term hard work, many elderly people who have experienced hardships in life suffer from physical discomfort when they should have spent their old age in peace. Lumbar disc herniation, old cold legs, arthritis, frozen shoulder and other diseases often afflict many middle-aged and elderly people. In response to the above conditions, various health devices such as lumbar pillows and neck pillows have appeared on the market to help those affected Consumers with pain in the waist and neck relieve their pain. [0003] In order to meet the requirements of low cost, low noise, and balanced massage force, a considerable number of health devices on the market are driven by air pressure, that is, the air bag is inflated and deflated by the air pump to realize the back and f...

AI Technical Summary

Problems solved by technology

Existing, the air filling chamber communicated with the air pump is connected with multiple massage devices, and when the inflation port of the air filling chamber is not fully inserted, the air filling interface will leak and cause the entire air supply to be damaged. Devices and health devices cannot be used, but in practical applications, health devices such as neck massage, waist massage, and knee massage are not often used. However, in order for the air pump and health devices to work properly without leaking air, either the above Plug in all the health devices, or install an on-off valve for each inflatable interface separately, and open and close according to the actual application when using it, which is very inconvenient to use
