  • Patent number: 9677961
    Abstract: A pressure indicator with a pressure-relief function is disclosed, which can release excessive pressure to the environment. The pressure indicator includes a transparent tube defining therein a first bore and a second bore, and a slider which can be forced by the medium supplied from an external pressure source to move along the first and second bores of the transparent tube. In particular, the first bore has a diameter greater than the second bore, and a tapered annular surface is provided between the first bore and the second bore of the transparent tube. When the pressure of the medium exceeds a predetermined pressure, the slider can be forced by the medium to reach the tapered annular surface, at which excessive medium can be released into the environment via an annular gap between the slider and the tapered annular surface.

  • Patent number: 9664187
    Abstract: A pen-type 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 transparent tube and a slider. The slider can be moved along a first bore and a second bore of the transparent tube. The motion of the slider in the transparent tube is similar to the motion of a piston in a cylinder. The transparent tube is provided with a tapered annular surface, between the first bore and the second bore. In addition to measuring the pressure of the compressed air delivered to an object, when the pressure of the compressed air exceeds a predetermined pressure, excessive air can be released into the environment, without requiring the air compressor to be installed with a safety valve, so that the object can be protected from damages due to overpressure.

  • Publication number: 20170126099
    Abstract: An electric motor generally includes a housing, a cover, and a cooling fan. The cover defines multiple inlet holes and is formed integrally with an air collecting ring around the inlet holes so as to provide an airflow path for allowing a central portion of the air current generated by the cooling fan to enter the housing. The housing defines a plurality of communication holes and a plurality of outlet holes for allowing the air which has entered the housing to flow thereout. In addition, the present invention provides another path so that an outer portion of the air current can flow along the outer surface of the housing to reduce the temperature of the housing. Through multiple paths for heat dissipation, heat is not easy to accumulate in the housing of the electric motor.

  • 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.

  • Patent number: 9550333
    Abstract: A sealant dispenser, which can cooperate with an air compressor for repairing punctured tires, is disclosed. The sealant dispenser generally includes a bottle with a top opening being filled with a chemical sealant, a cap mounted over the top opening of the bottle, a control valve for controlling an air passage and a sealant passage defined at the cap, and a rotary handle. In use, the air passage receives compressed air from the air compressor, and the sealant passage is connected to a tire to be repaired. By turning the rotary handle, the air passage and the sealant passage can communicate with the inner space of the bottle, which allows the compressed air to flow into the inner space of the bottle to force the chemical sealant contained therein to flow into the interior of the punctured tire, thus repairing the tire.
