BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure device for filling compressed air into a spray container or the like which can be used many times.

[0002]

2. Description of the Related Art A spray container is widely used for spraying various propellants, but as a propellant gas, a chlorofluorocarbon gas and an LPG have been widely used. However, the use of such a propellant gas has problems such as adverse effects on the environment and flammability, and in recent years, it has been known that a substitute for the propellant gas is obtained by pressurizing and filling compressed air. became. As these pressure filling means, there are a means using a manual pump and a means using a compressor (for example, Japanese Patent Publication No. 57-36020).

DISCLOSURE OF THE INVENTION The present invention relates to an improvement of an automatic pressurizing device using a compressor. Particularly, a locking means for preventing the spray container from floating is simple, and if it is not locked, a start switch is turned on. It is an object to provide a safe pressurizing device.

[0004]

Therefore, in the present invention, a gas injection section consisting of a recess provided at the bottom of the spray container is provided.
In a sprayer automatic pressurizing device which is fitted into a gas injection pipe provided in a pressurizing device and filled with compressed air from a compressor, the gas injection pipe is rotatably provided, and with the rotation of the gas injection pipe. A stopper unit that engages with the head of the spray container attached to the gas injection pipe, and a start switch that is pressed by the spray container are provided in the pressurizing device main body, and the stopper unit and the start switch are
The head of the spray container and the stopper were engaged with each other before the spray container pressed the start switch.

[0005]

The pressurizing device of the present invention having the above construction can be used with peace of mind because the starting switch cannot be turned on unless the spray container is completely engaged with the stopper portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The automatic atomizer pressurizing device according to the present invention is based on the base 2
Compressor 10 including control circuit block 4, motor 6 and cylinder 8 placed on top, compressor 1
A pressure sensor 12 for detecting the pressure of the compressed air from 0, a solenoid valve 14 for releasing the compressed air to the outside when the pressure of the pressure sensor 12 reaches a constant value, and a spray container 15 described later for filling the compressed air with the compressed air. The gas injection part 16, the stopper part 18 for fixing the spray container 15 at the time of filling, and the starting switch 20 for starting the compressor 10 are mainly constituted, and are covered by an outer case (not shown).

The control circuit block 4 is for electrically controlling the entire pressurizing device, and the main switch 2 is provided on the upper surface thereof.
2. Confirmation lamps 24 and 26 are mounted. The confirmation lamps 24 and 26 are for confirming whether the pressure of the spray container 15 has reached a certain level or whether the pressure is being filled, and when it is turned on, the state is displayed. The compressor 10 is controlled by a start switch 20. Compressed air from the compressor 10 is guided to the pressure pipe 28, and is sent to the pressure sensor 12 and one end of the gas injection unit 16 via the electromagnetic valve 14.

The gas injecting section 16 is composed of a gas injecting pipe 32 for sending compressed air into the spray container 15 and a support shaft 34, and is rotatably supported by a fixed base 30. A wide opening 33 is formed in one of the support shafts 34, and a ventilation hole 35 is formed from the opening 33 to the tip of the gas injection pipe 32. A tube 36 is press-fitted so as to cover the opening 33 and allow compressed air from the pressure pipe 28 to flow into the opening 33. An O-ring 31 is attached in the middle of the gas injection pipe to prevent compressed air from leaking to the outside at the time of fitting with a spray container described later.

The start switch 20 is composed of a micro switch 40 fixed to a support 38 and an operator 42. The motor 6 is turned on and off by turning the micro switch 40 on and off.
Turn off control. The stopper portion 18 is fixed to the upper part of the support base 44 and has a half donut shape, and is for preventing the spray container 15 from moving when the spray container 15 described later is filled with compressed air. is there.

The spray container 15 includes a cylinder 46 and a nozzle 47.
A concave portion 50 which is formed of a lid portion 48 having a cylindrical shape, and into which the gas injection pipe 32 can be pressed from the bottom portion of the cylinder 46 toward the inside
Is formed. A valve (not shown) prevents the backflow of compressed air at the tip of the recess 50. The lid 48 is a cylinder 4
6 is detachably screwed, so that the spray agent can be easily replaced.

To use this pressurizing device, first, the main switch 22 is turned on. Next, as shown in FIG. 2, the recess 50 of the spray container 15 is pressed into the gas injection pipe 32. Then, when the spray container 15 is rotated together with the gas injecting portion 16 as shown by an arrow A in FIG. 3, the lid portion 48 first engages with the stopper portion 18, and then the cylinder 46 of the spray container 15 is operated by the operator 42. Is pressed to turn on the micro switch 40. Therefore, the motor 6 is activated and the compressed air is filled in the spray container 15. In order to prevent the pressure in the spray container from being filled above a certain value, the pressure sensor 12 measures the pressure, and when it reaches a certain value, the compressed air is discharged to the outside via the solenoid valve 14. 5
Reference numeral 2 denotes a control signal line from the control circuit block 4.

[0012]

As described above, according to the present invention, the engagement with the head stopper portion of the spray container is arranged at a position earlier than the spray container pressing the start switch, so that the structure is simple and A safe pressurizing device can be provided.
