## Abstract

A Presta valve connector includes a housing and a stripping assembly rotatably connected to the housing. The housing is provided with a channel and an airtight ring having a connection hole. The airtight ring and the stripping assembly are disposed at two opposite ends of the channel. One end of the stripping assembly is disposed in the channel, and another end of the stripping assembly is exposed out of the channel. One end of the stripping assembly is provided with a driving groove faced to the connection hole. The driving groove is provided with a first driving face formed as a plane.

## Claims

### Claim 1

A Presta valve connector comprising:
a housing provided with a channel, wherein one end of the channel communicates with the outside of the housing and is provided with an airtight ring having a connection hole; and
a stripping assembly rotatably connected to the housing about a rotation axis and movable in relative to the housing in the rotation axis, wherein the airtight ring and the stripping assembly are respectively disposed at two opposite ends of the channel, wherein the stripping assembly defines a first end and a second end along the rotation axis, wherein the first end of the stripping assembly is disposed in the channel, wherein the second end of the stripping assembly is exposed out of the channel, wherein the first end of the stripping assembly is provided with a driving groove recessed in the rotation axis and faced to the connection hole, and wherein the driving groove is provided with a first driving face formed as a plane parallel to the rotation axis.

### Claim 2 (depends on 1)

The Presta valve connector as claimed in claim 1, wherein the driving groove is provided with a second driving face formed as a plane parallel to the first driving face.

### Claim 3 (depends on 2)

The Presta valve connector as claimed in claim 2, wherein the stripping assembly includes a driving rod and a switch member, wherein a proximal end of the driving rod is disposed in the channel, and wherein a distal end of the driving rod is exposed out of the channel, wherein the driving groove is disposed at the proximal end of the driving rod, and wherein the switch member is rigidly connected to the distal end of the driving rod and is exposed out of the out of the channel.

### Claim 4 (depends on 3)

The Presta valve connector as claimed in claim 3, wherein an inner periphery of the channel is provided with a first section and a second section disposed at one side of the first section opposite to the airtight ring, wherein a diameter of the second section in a radial direction of the channel is less than a diameter of the first section in the radial direction of the channel, wherein the driving rod includes a head portion disposed in the first section and a body portion connected to the head portion, wherein a diameter of the head portion in a radial direction of the rotation axis is greater than the diameter of the second section in the radial direction of the channel, wherein one end of the body portion is connected to the head portion, wherein another end of the body portion opposite to the head portion extends through the second section and is exposed out of the channel, and wherein the switch member is rigidly connected to the body portion.

### Claim 5 (depends on 4)

The Presta valve connector as claimed in claim 4, wherein the inner periphery of the channel is provided with a third section disposed between the first and second sections, wherein a diameter of the third section in the radial direction of the channel is less than the diameter of the first section in the radial direction of the channel and is greater than the diameter of the second section in the radial direction of the channel, wherein a seal ring and a stopper are located in the channel, wherein the seal ring is disposed in the third section, wherein the stopper is disposed in the first section and abuts against a side of the seal ring opposite to the second section, and wherein the seal ring and the stopper are mounted around the body portion.

### Claim 6 (depends on 5)

The Presta valve connector as claimed in claim 5, wherein the body portion is provided with a first insert hole in the radial direction of the rotation axis, wherein the switch member is provided with a second insert hole in the radial direction of the rotation axis, and wherein the stripping assembly includes a connection member mounted through the first and second insert holes.

### Claim 7 (depends on 6)

The Presta valve connector as claimed in claim 6, wherein the housing is provided with an end cap disposed at one end of the channel and abutting against the airtight ring.

### Claim 8 (depends on 6)

The Presta valve connector as claimed in claim 6, wherein the housing is provided with an inlet passage communicating between two ends of the channel, wherein a positioning member, a pressure relief valve, and an elastic member are arranged in the inlet passage, wherein the positioning member is disposed at one side of the inlet passage in a radial direction of the inlet passage, wherein one end of the pressure relief valve is disposed at another side of the inlet passage opposite to the positioning member in the radial direction of the inlet passage, wherein another end of the pressure relief valve opposite to the positioning member is exposed out of the inlet passage, wherein one end of the elastic member abuts against the positioning member, and wherein another end of the elastic member abuts against the pressure relief valve.
