AI Technical Summary

Technical Problem

The existing valve design is prone to loss of the sealing plug, affecting its use, and is inconvenient to operate, making it difficult to achieve rapid inflation and deflation and good airtightness.

Method used

It adopts an L-shaped three-in-one air nozzle design, including a sealing cylinder, a sealing plug, and a connecting cylinder. Anti-slip grooves and anti-slip patterns increase stability. The sealing plug and connecting cylinder are integrated to ensure sealing. A limiting structure enables rapid inflation and deflation.

Benefits of technology

To prevent the sealing plug from being lost, improve the convenience and airtightness of inflation and deflation, ensure that the inflatable product does not leak air during use, and has good airflow and rapid inflation capability.

Abstract

The utility model belongs to the technical field of air taps, and particularly relates to an L-shaped three-in-one air tap which comprises a first main body, a sealing cylinder fixedly installed at the center of the bottom of the first main body, a sealing gasket arranged in the sealing cylinder, a sealing plug fixedly installed at the top of one end of the first main body, and a connecting cylinder fixedly installed at the top of the other end of the first main body. When the air cap nozzle is used, the sealing plug is moved out of the sealing cylinder, the air nozzle is placed in the air cap nozzle, the interior of an inflatable product is inflated, air penetrates through the air cap nozzle to push away the sealing gasket to flow into the product, when inflation is stopped, the sealing gasket is reset to prevent the air from flowing out, then the air cap nozzle is taken out, and the air cap nozzle is taken out. The sealing plug is clamped into the sealing cylinder to seal the sealing cylinder, it is guaranteed that the inflatable product cannot leak air in the using process, and meanwhile the sealing plug and the connecting cylinder are integrally arranged, so that the independent sealing plug can be prevented from being lost.
