  • AIR COMPRESSOR
    Publication number: 20160258431
    Abstract: An improved motor includes a cylinder defining multiple exit holes of different diameters, which are respectively controlled by a resilient sheet having multiple branches to communicate with an air storage container. In operation, when a piston body conducts reciprocating motion in the cylinder, the compressed air produced in the cylinder can quickly enter the air storage container. The branches of the resilient sheet are subjected to different back force resulting from the compressed air in the air storage container, wherein the smallest branch of the resilient sheet is subjected to a smallest back force, so that the compressed air produced in the cylinder can enter the air storage container more easily through the smallest exit hole, so that the piston body can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.

  • MOTOR WITH HEAT DISSIPATION STRUCTURE
    Publication number: 20160238030
    Abstract: A motor includes a cylindrical housing, a cooling fan, and a rotating shaft. The cylindrical housing defines at least one upstream through hole at its circumferential wall. The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor. The hollow hood is mounted to the cylindrical housing such that a head portion is located above the upstream through hole, thus defining an annular air-guiding channel therebetween, which can receive the airflow generated by the cooling fan and guide the airflow to enter the cylindrical housing via the upstream through holes, so that the heat generated therein can be dissipated effectively. Thus, heat is not easy to accumulate in the motor, and the performance and service life of the motor can be increased.

  • AIR COMPRESSOR
    Publication number: 20160237996
    Abstract: An improved air compressor includes a cylinder that is fitted with a piston body and defines at its top wall a plurality of exit holes having different diameters and communicating between the cylinder and an air storage container. The exit holes are sealed by plugs and compression springs. The exit holes allow the compressed air produced in the cylinder to enter the air storage container more quickly. When the piston body approaches the top wall of the cylinder, one exit hole, with a smaller diameter, allows the compressed air to enter the air storage container more easily. The exit holes with different diameters allow the piston body to move in the cylinder more smoothly, and thus the efficiency of inflating an object can be increased.

  • AIR COMPRESSOR
    Publication number: 20160102661
    Abstract: An improved air compressor includes a cylinder with a piston body and an air storage container. The air storage container can be detachably mounted to the cylinder to define a primary air chamber, and an auxiliary air chamber which can reduce the motion resistance of the piston body, so that the piston body can conduct reciprocating motion in the cylinder more smoothly. Furthermore, the cylinder has an open bottom that is divided into two halves according to a central vertical line (Y) of the cylinder, wherein one half of the open bottom is horizontal while the other half of the open bottom is slanted. When the piston body reaches the bottom dead center, the head of the piston body will be entirely within the cylinder and thus keep air-tight with the cylinder. Therefore, the performance of compressing air and the operational safety can be increased.
