  • Pressure indicator for air compressor
    Patent number: 9562821
    Abstract: A pressure indicator, which can be detachably connected to an air compressor for measuring the pressure of compressed air produced in the air compressor, includes a tube and a slider. The slider can be moved along a first bore and a second bore of the tube. The motion of the slider in the tube is similar to the motion of a piston body in a cylinder. The tube is provided with a tapered annular surface, between the first bore and the second bore, and defines an elongated opening. In addition, when the pressure of the compressed air exceeds a predetermined pressure, excessive air can be released into the ambient environment, without using a mechanical safety valve, so that an object can be prevented from over-inflation.

  • MOTOR STRUCTURE
    Publication number: 20170033642
    Abstract: An improved motor structure includes a housing and a cooling fan for generating an air current that can quickly enter the housing to dissipate heat therein. The housing is pressed to form a plurality of intercepting fins and a plurality of inlet holes. The air current can be guided by the intercepting fins so that it can pass through the inlet holes more easily to enter the inner space of the motor's housing to take away the heat generated in the motor, so that heat is not easy to accumulate in the housing of the motor, and thus maximum power output of the motor can be achieved. Therefore, the performance and service life of the motor can be increased.

  • 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.

  • 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.

    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.
