    BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to inflation devices and more particularly to a flexible nozzle head for an inflation device. 2. Description of the Prior Art [0002] The conventional portable inflation device (i.e., a mini pump) that can be transported with a bicycle generally has its head and body forming a single piece. Such an inflator, when used to inflate a tire, tends to pull the tire valve and, therefore, has its head detached from the tire valve, or tends to tear the inner tube. tire where the head is connected.
    To solve the above problem, an improvement has been made to the known inflation device. In this, the head of the inflator is attached to a hose, and the hose is embedded in the pump body of the inflator. The head is pulled out during use and is retracted into the pump body of the inflation device for storage. Although such a configuration prevents the above problem, it is not perfect because, to receive the pipe, the pump body must be provided with an additional inner tube which occupies space in the pump body and reduces the effective inflation capacity of the inflation device, since the inner tube only functions to receive the hose and is not part of the cylinder where the compressed air is formed. Thus, such an inflator is still inferior to conventional devices in terms of inflation efficiency.
    BRIEF SUMMARY OF THE INVENTION
    The main objective of the present invention is to provide a nozzle head for an inflation device. The nozzle head is resiliently flexible, so that when it is used to inflate a tire, it is unlikely that it pulls the tire valve. In addition, the nozzle head does not occupy space in the pump body (cylinder) of the inflation device, thus ensuring good inflation efficiency.
    To achieve the above purpose, the disclosed flexible nozzle head for an inflation device comprises a head end housing, having a receiving space for receiving a nozzle head component; a pump end housing, which is fixedly connected to an end of a pump body of the inflation device; and a pipe, one end of which is airtightly molded onto the head end housing, in one piece, and having an opposite end connected to the pump end housing in an airtight manner . The head end housing has a through hole in communication with the receiving space and an axial pipe of the pipe. The pump end housing has an interior in communication with the axial conduit of the pipe.
    According to another aspect of the invention, the pump end housing is substantially tubular, with one end fixedly connected to the pump body of the inflator and an opposite end forming a receiving cavity which extends inwardly, the opposite end of the pipe having an enlarged outer diameter end portion, the end portion being received in the receiving cavity of the pump end housing, and a retention member being provided at the opposite end of the pump end housing for retaining the end portion of the pipe within the receiving cavity of the pump end housing.
    According to another aspect of the invention, a nonreturn valve is attached to one end of the pump end housing which is fixedly connected to the inflation device.
    According to another aspect of the invention, the retention element is formed by two semi-annular elements combined in a ring, the ring defining at its center a through hole to allow the pipe to pass through it, the hose having its end portion movably engaged in the receiving cavity of the pump end housing.
    According to another aspect of the invention, the end portion of the pipe comes into peripheral contact with the inner wall of the receiving cavity of the pump end housing, in a watertight manner. air.
    According to another aspect of the invention, the opposite end of the pump end housing extends outwardly to form two shoulders for holding and positioning the head end housing therebetween.
    According to another aspect of the invention, the nozzle head comprises: a head end housing having a receiving space for receiving a nozzle head component; a pump end housing, which is fixedly connected to an end of a pump body of the inflation device; and a pipe, one end of which is overmolded with the head end housing, airtight in one piece, and having an opposite end also overmolded with the pump end housing, sealingly to air and in one piece, the head end housing and the pump end housing each having a through hole which communicates with an axial pipe of the pipe.
