Problems solved by technology

For example, in the case where an auxiliary tank is added to the above-mentioned battery-type air compressor in order to provide a large amount of compressed air, the remaining power of the battery is likely to be insufficient due to the need for large-capacity power, so the battery must be taken out repeatedly. As a result of recharging or replacement, workability is significantly impaired due to interruption of work

Embodiment Construction

[0031] Combine below Figure 1 ~ Figure 3 Embodiments of the present invention will be described. Such as figure 1 The air compressor device 1 in the first embodiment shown includes a rechargeable compressor body 10 and an external tank 30 connected to the compressor body 10 . The external tank 30 is connected to the compressor body 10 through the air hose 11 . In addition, the external tank 30 is electrically connected to the compressor body 10 through the power cord 12 .

[0032] An air compressor unit 14 having a motor 13 as a drive source is installed in the compressor body unit 10 . The action of the motor 13 is controlled by the control circuit 15 . The motor 13 is driven by a battery (body battery 16 ) as a power source. When the power switch 22 is in the ON (starting) state, the body battery 16 provides power for the motor 13 . The body battery 16 can be used repeatedly by removing it and charging it with a separately prepared charger.

[0033] In addition, a po...

Abstract

An air compressor is provided. When a small-size light movable air compressor is used, situations of insufficient supply of compressed air may occur according to the job content. In the prior art, an external storage tank is adopted to solve the insufficient supply of the compressed air, but the problem of insufficient electric power supply may occur. The external tank in the present invention can not only supply compressed air but also electric power. The air compressor (1) may include a compressor unit (10) which provides compressed air for an air tool T and an external tank unit (30) connectible with the compressor unit (10). The external tank unit (30) may include a battery (37) for supplying electric power to the compressor unit (10).

Description

technical field [0001] The present invention relates to an air compressor device, which is used to provide compressed air for pneumatic tools, and the pneumatic tools include, for example, compressed air-driven nailers or air nail guns. Background technique [0002] A simple air compressor. Compared with the fixed large-scale air compressor, although the exhalation capacity of the compressor is small, it has the characteristics of small size, light weight, and easy handling. It can play a role in pneumatic tools when it is used Big convenience for easy light work. Patent Documents 1 and 2 below disclose technical features of a simple air compressor using a battery (DC power supply) as a power source. [0003] The structure of this simple air compressor is as follows: a motor and a compression part are accommodated inside its resin casing, and the compression part converts the rotational output force of the motor into the reciprocating motion of the piston in the cylinder an...
