Description

Inflator that can be manually or connected to a gas cylinder

The present invention relates to an inflator for inflating an object such as a tire, an air cushion, or the like, and particularly an inflator that can be easily converted into a manual air pump or a gas cylinder.

A general pump generally includes a cartridge, a head disposed on the cartridge, and an inflation nozzle disposed on the head. The inflation nozzle is connected to the nozzle of the inflated body to generate compressed gas by operating the cartridge, thereby The gas is charged into the inflated body through the head, the inflator, and the air nozzle.

Based on the convenience of carrying, the mini-type portable pump is popular among long-distance bicycle riders; as shown in the first figure, the conventional portable pump A includes a cylinder A1 and a relative to the cylinder A1. a moving head A2, and an inflating nozzle A3 disposed on the head A2; when inflating, the inflating nozzle A3 is screwed to the inflating nozzle, and then the cylinder A1 is operated to move axially relative to the head A2. The gas can be charged into the inflated body via the head A2 and the inflator A3 by manual operation. The detailed structure and use of the portable pump shown in the first figure can be referred to the TW M315778 patent.

Because manual air pumping is cumbersome and laborious, and air compressors with fast and labor-saving aeration effects are inconvenient or even impossible to carry around, high-pressure gas cylinders that are small and convenient to carry are popular choices, especially for long-distance bicycle riders. It is more practical. As shown in the second figure, the gas cylinder C is a metal bottle body with a certain strength, and the inside thereof is filled with a high-pressure gas (generally carbon dioxide, CO ₂ ), and the bottle mouth is sealed with a metal film; when the tire or other tires are to be When inflated by the inflator, a cylinder connector B must be connected to the mouth of the cylinder C to pierce the metal film by the tapered tapered piercing member provided in the cylinder connector B, and the piercing member is utilized at the same time. The tapered shape plugs the hole through which the metal film is punctured, and then the inflation nozzle B1 of the cylinder connector B is screwed to the gas nozzle of the inflated body, and then the cylinder C is operated to rotate the piercing member appropriately. Disengaging the pierced hole and connecting the cylinder connector B and the cylinder C, so that the high-pressure gas in the cylinder C is filled into the inflated body through the cylinder connector B and the inflation nozzle B1; the cylinder C and the cylinder The connection or disconnection of the connector B is controlled by the cylinder connector B and the cylinder C rotating forward or backward. The detailed structure and usage of the cylinder connector B of the second figure can be referred to the TW I405927 patent.

In combination with the prior art described above, conventional air cylinders cannot be directly connected to a gas cylinder for rapid inflation; conventional gas cylinders must be used in conjunction with separately purchased gas cylinder joints; that is, conventionally, two types of inflation nozzles must be provided. It is necessary to connect the manual pump and the gas cylinder separately; if the two devices of the general pump and the gas cylinder are to be prepared, the carrying is inconvenient and the money is high.

The purpose of the invention is to integrate the general pump with the cylinder connector, so that the pump has only one inflation joint, so that the user can choose to inflate the inflated body by general manual airing, or conveniently convert.
