Valve connector adaptable to multiple valve types

Abstract

This invention relates to a nozzle head applicable to various air nozzles, comprising a housing and a supporting device. The housing has a first end, a second end, and a groove connecting the first end and the second end along a virtual through-axis. The supporting device includes a slider, a movable center, and an elastic member. The slider is axially movable within the groove along the through-axis. One end of the slider has a center portion and the other end has a center groove. The center portion is adjacent to the first end, and the center groove is adjacent to the second end. The movable center is axially movable within the center groove along the through-axis. The elastic member is located within the center groove. One end of the elastic member abuts against the slider, and the other end abuts against the movable center, moving away from the center portion. The nozzle head, through the above structure, can be used with various air nozzles.

Claims

1. A nozzle head applicable to various air nozzles, comprising: a housing having a first end, a second end, and a groove connecting the first end and the second end along a virtual through-axis; A backing device includes a slider, a movable center, and an elastic element. The slider is axially movable within a groove along a through-axis. One end of the slider has a center portion and the other end has a center groove. The center portion is adjacent to a first end, and the center groove is adjacent to a second end. The movable center is axially movable within the center groove along the through-axis. The elastic element is disposed within the center groove. One end of the elastic element abuts against the slider, and the other end abuts against the movable center, moving away from the center portion. The backing device includes a sleeve connected to the slider and adjacent to the center groove. The sleeve has a through hole and a flange on the inner periphery of the through hole. In its natural state, the movable center is pushed by the elastic element and abuts against the flange. The through hole allows an air nozzle to be inserted, with the air nozzle abutting against the side of the flange opposite to the movable center.

2. The air nozzle applicable to various air nozzles as described in claim 1, wherein the abutting device includes a lever, the lever being rotatably pivotally mounted on the housing between a first position and a second position, one end of the lever being provided with a pushing part and the other end being provided with a lever part, the pushing part being radially inserted into the slide groove along the through axis and abutting against the slider, the lever part being protruding outside the housing, when the lever is in the first position, the pushing part pushes the slider to move towards the first end, and when the lever is in the second position, the pushing part pushes the slider to move towards the second end.

3. The nozzle head applicable to various air nozzles as described in claim 2, wherein the housing is connected to a first cover and a second cover, the first cover being fitted onto the first end and the second cover being fitted onto the second end, a first airtight ring and a second airtight ring are provided in the slide groove, the first airtight ring being adjacent to the first end and the second airtight ring being adjacent to the second end, when the lever is in the first position, the slider compresses the first airtight ring, and the end of the first airtight ring opposite to the slider abuts against the first cover, when the lever is in the second position, the slider compresses the second airtight ring, and the end of the second airtight ring opposite to the slider abuts against the second cover.
