Benefits of technology

[0010] A further object of the present invention is to provide an improved structure for an air pump, wherein the motor body and the cylinder can be rapidly cooled, and the device is operating effectively.

Problems solved by technology

This conventional air pump reduces the noise production from the motor but heat dissipation problem of the motor is occurred.
This drawback (heat) may cause the motor being overheated and damaged.
Further, the air pump may not function properly to provide sufficient pressurized air.
The conventional motor A1 does not provide heat dissipation in the course of operation.
Thus, the function of the conventional air pump is restricted by the gear system as well as the shaft.

Embodiment Construction

[0025] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0026] Referring to FIGS. 1 and 2, the air pump of the present invention comprises a motor body 1, a cylinder seat 2, a silencer cap 3, an eccentric gear 4, a piston 5, and a cylinder top cap 6.

[0027] The motor body 1 employs a sealing cap 11 to seal off the front and rear openings thereof. The front sealing cap 11 allows the main shaft 12 to be protruded and is provided with a plurality of air inlets 13. After the main shaft 12 passes through a shaft hole 21 on the cylinder seat 2, a locking ...

Abstract

An improvement in the structure for an air pump, and in particular, an air pump, which is sealed to isolate the noise of operation, and the motor body and the cylinder, can be rapidly cooled. The improved air pump employs the circulation of air to the motor so as to lead the external air to the cylinders of the pump so as to keep the motor body and the cylinder at a cooler temperature. This allows the motor to work effectively and efficiently.

Description

CROSS-REFERENCE [0001] This application is related to U.S. Pat. No. 6,716,003, owned by the same applicant.BACKGROUND OF THE INVENTION [0002] a) Field of the Invention [0003] The present invention relates to an improvement in structure for an air pump, and in particular to an air pump which is sealed to isolate the noise of operation, and of which the motor body and the cylinder can be rapidly cooled. [0004] b) Description of the Prior Art [0005]FIG. 10 shows a closed type mini size air pump A1. The pump A1 includes a motor body A2 and a cylinder body A3. This conventional air pump reduces the noise production from the motor but heat dissipation problem of the motor is occurred. This drawback (heat) may cause the motor being overheated and damaged. Further, the air pump may not function properly to provide sufficient pressurized air. Occasionally the pump has to be stopped in order to provide a proper function. The cylinder top cap A2 is provided with a sealing pad A5. [0006] Howeve...
