Description

Air compressor {AIR COMPRESSOR}

FIELD OF THE INVENTION The present invention relates generally to air compressors that produce compressed air and, in particular, for the realization of noiseless operation, eccentric rotating members set to rotate to cause opposite compression of extensible barrels. eccentric rotation members).

In providing a mechanical power source, compressed air is advantageous in terms of low cost and low pollution. Thus compressed air is widely used to operate pneumatic devices, pneumatically actuated means or to facilitate the operation of mechanical devices. Air compressors are often used to convert atmospheric air into compressed air, and motors are used to operate the air compressor. The motor draws air into the cylinder and compresses it into pressurized air for immediate use or reciprocating the piston in the cylinder for storage in a high pressure reservoir. As technology advances, a variety of pneumatic means are used in the market to replace human labor and improve operational efficiency.

However, conventional air compressors often produce loud noises during operation, which is primarily due to their mechanical structure. In a conventional air compressor having an open structure, when set to a regular-load operating condition, the noise generated can reach 90 decibels (dB). Such loud noises often damage the body by constricting blood vessels, raising blood pressure, causing dizziness, and making a person easily irritable. Taiwan Utility Model No. 162789 discloses a box-type air compressor having a quiet, high heat dissipation function, wherein a part of the air compressor is arranged inside a main enclosure box formed by side boards, The sealed box blocks the outflow of noise. The motor provided inside the sealed box has a spindle having an exposed end connected to a multi-blade fan. The feed fan is a high performance heat dissipation by directing the flow of air delivered through the air pipe to the fan-shaped belt pulley provided in the front end of the cylinder and the cylinder so that a large amount of cooling air is blown out as part of the air compressor. .

However, since the above-mentioned solution only lowers the degree of noise to some extent and heat dissipation to some extent, it does not substantially eliminate the problem of noise of the conventional air compressor.

An object of the present invention is to provide a cylinder and cylinder head portion of a conventional air compressor using a transmission system that causes reciprocation up and down and an extensible barrel made of a material having elasticity and elongation-resisting. It is to provide an air compressor having a feature that eliminates the noise caused by the air compressor according to the conventional manner, and also easy to maintain and maintain by replacing the.

An air compressor according to the present invention for achieving the above object comprises a chassis, a motor, a transmission set and a plurality of extensible barrels, wherein the motor, transmission set and extensible barrels are It is mounted on the chassis. Bearing seats are provided on opposite sides of the chassis. The transmission set includes a clutch connected to the motor via a belt. Two eccentric rotation members are connected to the clutch, with the eccentric rotation members respectively disposed opposite each other with the clutch interposed therebetween, the eccentric rotation members having shafts rotatably supported by the bearing seats. It has an outer side face. Each eccentric rotating member is connected to a crank arm. Each extensible barrel has a circumferential surface forming a corrugation, the corrugation consisting of a plurality of alternating troughs and ridges, each of which is a reinforcing ring (reinforcing ring). The extensible barrel has an air inlet port at the center of its uppermost portion and an air discharge port at the center of its lowermost portion. The air inlet port and the air outlet port have check valves and filters, respectively.

In the operation of the present invention, the mechanical power source generated by the driving of the motor is used to rotate the entire transmission set, and the extensible barrels are opposed to each other by causing the crank arms to move to cause opposite motions to each other. Axial compression is performed, through which air is introduced into the extensible barrels through the air inlet ports and then discharged into the compressed air through the air discharge ports of the extensible barrels. Since the extensible barrels applied to the present invention have elasticity and elongation-resisting, no noise is generated during operation of the air compressor according to the present invention, and in case of failure, efficient replacement and convenient maintenance, Maintenance can be done quickly.

The present invention has the following advantages.

(1) The present invention uses the motor 2 to drive the transmission set 3 and the extensible barrels 4, and also structurally reinforces the extensible barrels 4 to draw in air. Compression and discharge are all done within a single operating cycle, providing excellent operating efficiency, no noise during operation, and efficient replacement to simplify repairs, maintenance and maintenance in the event of a fault.

(2) The present invention further provides maneuverability by providing casters 13 at the bottom of the chassis 1.
