Gas nozzle joint structure shared by pump and cylinder (1)

The invention relates to a gas nozzle joint structure which is shared by a gas cylinder and a gas cylinder; in particular, the utility model can simultaneously exert the effect of providing gas nozzle gas whether installed in an air pump or unplugged and installed in a gas cylinder.

Conventional bicycles are equipped with air-inflating devices, which are mainly divided into two types, one is an inflator, which is manually inflated, and the other is a gas cylinder (CO2 cylinder), which is inflated with internal high-pressure gas. Advantages and Disadvantages, using the pump to inflate, regardless of the size of the tire, can fully fill the tire, but its inflation rate is slower and more labor-intensive; use the gas cylinder to inflate, fast, labor-saving, but after use It must be discarded, it cannot be reused, and its capacity is fixed. There is often a case where a canister is still not enough to fill the tire. Therefore, the current general inflation method is to use a connecting device and a tire nozzle to perform an inflating operation, so that the high-pressure gas in the cylinder is filled into the tire from the tire nozzle through the connecting device, and After the gas cylinder is still not enough to fully fill the tire, the connecting device and the gas cylinder are detached from the tire air nozzle, and then the air nozzle joint of the air pump is used to connect with the tire air nozzle to perform the charging operation manually until the tire The wheel is full. However, in addition to carrying the pump and the gas cylinder in the vehicle, it is necessary to carry the special connection device of the gas cylinder, and has the disadvantage of being inconvenient to carry. In addition, it needs to remove the connection device together with the gas cylinder after the gas cylinder is inflated. Mouth, then use the air nozzle connector of the pump and the tire nozzle group It is very inconvenient to operate, and it is necessary to improve it.

For example, in M448568, "The structure of the nozzle joint shared by the pump and the cylinder", the design of the pump and the cylinder can share a joint, but the outlet can not be surely controlled when the cylinder is used.

For example, in the "double-inflated pump" of M426663, the design of the pump and the cylinder can share a joint, but the pump and the cylinder must be connected to the joint at the same time, resulting in an overly complicated structural design and when used. The volume of the connection between the pump and the cylinder is too large.

For example, "Structural Improvement of High Pressure Inflator", No. M441041, this design provides gas cylinder connection. Although it has a control device for pressing and controlling the air, it can surely control the gas output when using the gas cylinder, but it cannot provide the same at the same time. The connection of the gas cylinder is used.

At present, the known gas nozzle joints have disadvantages, and can not be used at the same time as the gas cylinder and the gas cylinder; 2. the structure of the gas cylinder without the control switch; 3. the inconvenience of operation; 4. the large volume of the structure.
