Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressurizing device for filling compressed air into a spray container or the like that can be used many times.

[0002]

[Prior Art]

 Although spray containers are widely used for spraying various propellants, Freon gas and LPG have generally been used as the propellant gas. However, the use of such a propellant gas has problems such as adverse effects on the environment and flammability.In recent years, it has been known that a substitute for propellant gas is obtained by pressurizing and filling compressed air. Became. As these means for pressurizing and filling, there are a means using a manual pump and a means using a compressor (for example, Japanese Patent Publication No. 57-36020).

[0003]

[Problems to be solved by the device]

 The present invention relates to an improvement of an automatic pressurizing device using a compressor, and particularly provides a safe pressurizing device in which a locking means for preventing the spray container from floating is simple, and a start switch is not turned on unless it is locked. The purpose is to

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in the atomizer automatic pressurizing device for filling the compressed air from the compressor by fitting the gas injecting part consisting of the recess provided in the bottom part of the spray container with the gas injecting pipe provided in the pressurizing device, A gas injection pipe is rotatably provided, and the stopper is engaged with the head of the spray container attached to the gas injection pipe as the gas injection pipe is rotated, and is pressed by the spray container. A starter switch is provided on the main body of the pressurizing device, and the stopper portion and the starter switch are arranged at a position where engagement between the head of the spray container and the stopper portion is faster than the spray container pressing the starter switch. ..

[0005]

[Action]

 The pressurizing device of the present invention having the above-mentioned configuration 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.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The automatic atomizer pressurizing device according to the present invention comprises a compressor 10 including a control circuit block 4, a motor 6 and a cylinder 8 mounted on a base 2, and a pressure sensor 12 for detecting the pressure of compressed air from the compressor 10. , A solenoid valve 14 for releasing compressed air to the outside when the pressure of the pressure sensor 12 reaches a constant value, a gas injection section 16 for filling compressed air into a spray container 15 described later, and a spray container 15 fixed during filling The stopper portion 18 and the starting switch 20 for starting the compressor 10 are mainly constituted, and are covered by an exterior case (not shown).

The control circuit block 4 performs electrical control of the entire pressurizing device, and has a main switch 22 and confirmation lamps 24 and 26 mounted on the upper surface thereof. 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. 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-up switch 20 is composed of a micro switch 40 fixed to a support 38 and an operator 42. The micro switch 40 is turned on / off to turn on the motor 6. Turn off control. The stopper portion 18 is fixed to the upper part of the support base 44 and has a half donut shape to prevent the spray container 15 from moving when the spray container 15 described later is filled with compressed air. Is.

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

In the method of using 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. 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. The child 42 is pressed to turn on the micro switch 40. Accordingly, 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. Reference numeral 52 indicates a control signal line from the control circuit block 4.

[Effect of the device]

 As described above, in the present invention, since the engagement with the head stopper portion of the spray container is located at a position faster than the spray container presses the start switch, the pressurizing device has a simple structure and is safe. Can be provided.
