Dual-purpose nozzle

Abstract

A dual-purpose air nozzle includes: a connector cap; a hose connector, one end of which is a connecting end and the other end is a holding end, and an air passage is formed inside; the connector cap is fitted onto the hose connector; an air nozzle connector has a channel passing through both ends; an air nozzle connection portion is located at the bottom end of the air nozzle connector; the air nozzle connector is fitted onto the hose connector, located between the connector cap and the hose connector, and can be displaced and rotated relative to the hose connector; when the air nozzle connector is moved into the connector cap, it is in a retracted use position, and the holding end is located inside the air nozzle connection portion, so that the air nozzle can be connected to an air nozzle of one specification; when the air nozzle connector is moved out of the connector cap, it is in an unfolded use position, and the holding end is away from the air nozzle connection portion, so that the air nozzle can be connected to an air nozzle of another specification.

Claims

1. A dual-purpose air nozzle, comprising: a connector cap having a chamber; an opening located at the bottom end of the connector cap; a hose connector, which is a hollow cylindrical body, one end of which is a connecting end and the other end of which is a holding end; the connecting end is configured to communicate with an inflation device; an air passage formed in the hose connector; the connector cap is sleeved on the hose connector, the hose connector is located in the chamber, and the holding end of the hose connector is located at the opening of the connector cap; An air nozzle connector is a hollow cylindrical body with a channel extending through both ends; an air nozzle connection portion is located at the bottom end of the channel of the air nozzle connector; an airtight element is disposed at the bottom end of the channel of the air nozzle connector; the air nozzle connector is sleeved on the hose connector, located between the connector cover and the hose connector, and can be displaced and rotated relative to the hose connector to move into or out of the chamber of the connector cover; when the air nozzle connector is moved into the connector cover, it is in a retracted use position, and the top holding end is located inside the air nozzle connection portion; when the air nozzle connector is moved out of the connector cover, it is in an unfolded use position, and the top holding end is away from the air nozzle connection portion; a first connecting portion and a second connecting portion are respectively disposed on the connector cover and the air nozzle connector; when the air nozzle connector is in the retracted use position, the first connecting portion and the second connecting portion are detachably connected.

2. The dual-purpose nozzle as described in claim 1, wherein: The air nozzle connection has a lower screw hole with a larger diameter and an upper screw hole with a smaller diameter, with the upper screw hole located above the lower screw hole.

3. The dual-purpose air nozzle head as described in claim 2 includes: an air nozzle nut disposed at the bottom end of the channel of the air nozzle connector; the lower screw hole and the upper screw hole are disposed in the air nozzle nut.

4. The dual-purpose nozzle as described in claim 3, wherein: The airtight element of the air nozzle connector is located between the upper and lower screw holes of the air nozzle nut.

5. The dual-purpose nozzle as described in claim 3, wherein: The lower screw hole is located at the bottom end of the air nozzle nut, and the upper screw hole is located at the top end of the air nozzle nut; an annular groove is provided on the inner wall of the air nozzle nut, located between the upper and lower screw holes; the airtight element is annular and is provided in the annular groove.

6. The dual-purpose nozzle as described in claim 1, wherein: A leak-proof element is disposed between the outer peripheral surface of the hose connector and the inner wall of the air nozzle connector.

7. The dual-purpose nozzle as described in claim 1, wherein: One flange is located at the top of the channel of the air nozzle connector; a large diameter portion is located on the outer circumferential surface of the hose connector. When the air nozzle connector is in the unfolded use position, the flange abuts against the large diameter portion.

8. A dual-purpose nozzle as described in any one of claims 1 to 7, wherein: The first joint is located on the bottom side of the connector cover, and the second joint is located on the air nozzle connector.

9. The dual-purpose nozzle as described in claim 8, wherein: The first and second joints are internal threads and external threads or elastic retaining rings and retaining grooves.
