[0002] An air compressor is an industrial equipment that compresses gas. It is a device that converts mechanical energy into gas pressure energy. Air compressors are widely used in machinery, medical, food, automobile, chemical and building materials industries. The common piston compressors in our daily life include a gas tank, an electric motor installed on the gas tank, a drive mechanism driven by the electric motor and an exhaust pipe for transmitting gas. The electric motor drives the piston of the drive mechanism to make reciprocating linear motion in the cylinder to perform suction and exhaust actions. In addition, a capacitor device is usually fixed on the gas tank. The capacitor device is electrically connected to the motor, which can provide stable current, help the motor start, improve the efficiency of the motor, and protect the motor.

[0003] The current mainstream method of fixing capacitor devices is to first fix the bracket to the outer periphery of the gas tank by welding or screwing, and then fix the capacitor box to the bracket by screwing. This method requires tightening or loosening the screws when installing and removing the capacitor box, which is a relatively complicated process.

[0004] In view of this, it is indeed necessary to provide an improved air compressor to overcome the defects of the prior art. [Contents of the utility model]

[0005] In view of the deficiencies of the prior art, the purpose of the utility model is to provide an air compressor with an improved capacitor device installation method, which can conveniently and quickly install and remove the capacitor device on the air compressor.

[0007] A further improved solution is: the capacitor box includes a lower cover and an upper cover rotatably mounted on the lower cover, the capacitor box includes a notch penetrating the lower cover, and the capacitor box is inserted into the bracket through the notch.

[0008] A further improved solution is: the bracket includes a main body and a pair of extensions formed by bending upward from two ends of the main body, and the pair of extensions are inserted into the lower cover from the notch.

[0009] A further improvement scheme is: a pair of the extension parts include a through mounting hole, and the capacitor box includes a pair of quick-release baffles protruding upward from the inner side of the bottom of the lower cover; the pair of quick-release baffles protrude to the left and right sides respectively to form a protrusion, and the protrusion extends into the mounting hole to clamp the capacitor box on the bracket.

[0010] A further improvement is that in the left-right direction, the distance between the end faces of the two protrusions is greater than the distance between the outermost sides of the two extension portions.

[0011] A further improved solution is: a pair of anti-slip plates are provided on the outer sides of the pair of quick-release baffles, and the pair of anti-slip plates abut against the end faces of the extension parts.

[0012] A further improved solution is: the front side of the upper cover includes at least one buckle, the front side of the lower cover includes at least one hook, and the buckle and the hook cooperate with each other to lock the upper cover and the lower cover.

[0013] A further improved solution is: a receiving cavity is formed between the upper cover and the lower cover, and a capacitor is placed in the receiving cavity.

[0014] A further improvement is that the bracket is integrally formed of metal material.

[0015] A further improvement is that the capacitor box is integrally formed of plastic or metal material.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the capacitor device includes a bracket fixedly connected to the gas tank and a capacitor box plugged and fixed to the bracket; after the bracket is first fixed to the gas tank, a pair of quick-release baffles are pressed inwardly with one hand to insert the capacitor box into the bracket or remove the capacitor box from the bracket; this method is simple, quick and reliable in fixing the capacitor box.
