Description

This invention relates to a mobile battery-powered compressor that can supply compressed air to drive various devices.

A compressor is an air compressor that can use compressed air to drive tools such as air drivers and air tackers, or to spread pesticides and fertilizers in agricultural work. Many compressors that compress large amounts of air are powered by AC power, but battery-powered air compressors have also been proposed (see, for example, Patent Document 1). If they are battery-powered, compressed air can be used even in sites where there is no nearby AC power source.

Patent No. 5234243

The air compressor in Patent Document 1 detects the pressure in the storage tank, controls the motor that drives the compressor with a control device, and is provided with a pressure gauge that displays the air pressure being delivered through a pressure reducing valve, but does not have a pressure gauge that displays the detected pressure in the storage tank to the user of the device. In a battery-powered compressor, when the electrical capacity charged using the battery decreases, the compressor will not be driven sufficiently and the pressure in the storage tank will not increase. The pressure required in the storage tank needs to be higher than the air pressure being delivered. By replacing the battery, the pressure in the storage tank can be increased and the operating time can be extended. However, if the pressure in the storage tank is not displayed, it is not possible to know when the battery needs to be replaced.

The purpose of this invention is to provide a mobile battery-powered compressor that uses a mobile battery as its power source and can easily achieve continuous operation by simply replacing the battery.

The present invention comprises a cylindrical storage tank,
A motor, a compressor, and a mobile battery are arranged side by side in parallel with the extension direction of the storage tank,
an internal pressure gauge provided on the storage tank for indicating a pressure inside the storage tank;
a knob for adjusting the opening of a regulator valve that is arranged next to the internal pressure gauge on the storage tank and that adjusts the air pressure discharged from the storage tank;
a delivery pressure gauge arranged next to the knob on the storage tank for indicating the pressure of air delivered from the regulating valve;
The mobile battery can be attached and detached in the vertical direction next to the compressor.
This is a mobile battery-powered compressor characterized by the above.

In addition, in the present invention, the storage tank is provided with a hand-held handle that extends upward and then tilts upwardly of the motor, compressor and mobile battery.
It is characterized by:

In addition, in the present invention, a display panel is provided on the inclined portion of the hand-held handle,
the internal pressure gauge, the knob and the delivery pressure gauge are attached to a display panel;
It is characterized by:

According to this invention, if you prepare multiple charged mobile batteries, you can check the pressure inside the storage tank, which is displayed on the internal pressure gauge, and when the pressure stops increasing, you can replace the mobile battery you are using. With the mobile battery as the power source, continuous operation can be easily achieved by replacing the batteries.

The device also has a handle that allows it to be easily carried around.

In addition, this invention allows the internal pressure and the air pressure being pumped out to be easily compared and viewed on the display panel.

FIG. 4 is a photograph partially showing the handle 9 and the display panel 10 of FIG. FIG. 5 is a photograph partially showing the display panel 10 of FIG. FIG. 6 is a photograph substituted for a drawing showing the mobile battery 5 attached to the side of the compressor box 4 in the mobile battery type compressor 1 of FIG. FIG. 7 is a photograph showing the configuration of the back side of the display panel 10 of the mobile battery-type compressor 1 of FIG.

The configuration of one embodiment of the present invention will be described below with reference to Figures 1 to 7. In each figure, the same reference numerals are used for corresponding parts, and duplicate explanations may be omitted, and parts not shown in the figure being described may be referred to by reference numerals used in other figures.

1 and 2 show the external configuration of a mobile battery compressor 1, which is an embodiment of the present invention. The mobile battery compressor 1 includes a storage tank 2, a motor 3, a compressor box 4, a mobile battery 5, an internal pressure gauge 6, a knob 7, a delivery pressure gauge 8, a hand-held handle 9, and a display panel 10. The storage tank 2 has a cylindrical shape and is installed so that the extension direction is approximately horizontal. The motor 3, the compressor box 4, and the mobile battery 5 are arranged parallel to the extension direction of the storage tank 2 and lined up next to the storage tank 2. The compressor box 4 has a built-in compressor and its control unit, and a controller is fixed to the upper part. The mobile battery 5 is attached to the side of the compressor box 4 and can be attached and detached in the vertical direction. The internal pressure gauge 6 is provided on the storage tank 2 and displays the pressure inside the storage tank 2. The knob 7 is provided on the storage tank 2 next to the internal pressure gauge 6 and adjusts the opening of a regulating valve that adjusts the air pressure discharged from the storage tank 2. The delivery pressure gauge 8 is installed next to the knob 7 on the storage tank 2 and displays the air pressure delivered from the adjustment valve.

The mobile battery compressor 1 can use the compressed air drawn in from the air inlet 11 to drive tools such as an air driver or air tacker connected to an air hose connected to the outlet coupler 12, or to spread chemicals or fertilizers in agricultural work. The air that is blown out can be used in a wide range of applications, such as inflating tires or balls, blowing dust, and painting. However, the air pressure required differs depending on the application. If multiple charged mobile batteries 5 are prepared, the pressure inside the storage tank 2, displayed by the internal pressure gauge 6, can be checked, and when the output pressure no longer rises to the required air pressure, the attached mobile battery 5 can be replaced. Continuous operation can be easily achieved by replacing the batteries using the mobile battery 5 as the power source.

Figures 3, 4 and 5 show the configuration related to the hand-held handle 9. The storage tank 2 is provided with a hand-held handle 9 that extends upward and then tilts upwardly of the motor 3, compressor box 4 and mobile battery 5. The mobile battery compressor 1 can be easily moved by holding the hand-held handle 9.

The display panel 10 is located on the inclined portion of the handle 9, and is equipped with the internal pressure gauge 6, knob 7, and output pressure gauge 8. The internal pressure and output air pressure can be easily compared on the display panel 10, allowing appropriate decisions to be made, such as when to replace the batteries.

Figure 6 shows the mobile battery type compressor 1 of Figure 1 with the mobile battery 5 attached next to the compressor box 4. The mobile battery 5 is a lithium ion battery, with specifications of, for example, a voltage of 21 V and a capacity of 4.0 Ah. An attachment slot is provided on the side of the compressor box 4 to match the outer shape of the mobile battery 5, and parallel positioning bars are arranged in the vertical direction on both sides of the slot. A positioning slot is opened in the mobile battery 5 to match the positioning bar. A plug-in piece extending upward from the bottom is provided in the attachment slot. A plug-in hole that fits with the plug-in piece is provided at the bottom of the mobile battery 5. This makes it easy and reliable to attach and detach the mobile battery 5.

Figure 7 shows the configuration behind the display panel 10 of the mobile battery-type compressor 1 in Figure 1. Air in the storage tank 2 is led to the delivery pipe 14 via the extraction pipe 13. An adjustment valve 7a, the opening of which is adjusted with a knob 7, is provided midway along the delivery pipe 14. An internal pressure gauge 6 is connected to the delivery pipe 14 on the upstream side of the adjustment valve 7a. A delivery pressure gauge 8 is connected to the delivery pipe 14 on the downstream side of the adjustment valve 7a, and a delivery port coupler 12 is provided at the end.

In this embodiment, the compressor is built into the compressor box 4, and mounting slots for the controller and mobile battery 5 are provided, but the controller and mounting slots may be separate from the compressor.
