Hereinafter, embodiments of the present invention will be described with reference to the drawings.

5 to 7, a liquid cleaning agent feeding apparatus 100 according to the present invention includes an air compressor 10, an air tank 20, a liquid cleaner supply unit 30, an air hammer unit 40, (60) and a control means (COM).

The air compressor 10 is capable of compressing the air at a pressure of 5 to 30 kg / cm 2 , and is equipped with a drier capable of self-evaporating moisture in the introduced air to increase the compression efficiency. Here, the air compressor 10 is equipped with a solenoid valve S3 for high-pressure air.

The air tank 20 is a compressed air tank provided in communication with the air compressor 10 to fill the high pressure air supplied from the air compressor 10 and to maintain a constant pressure of the discharged high pressure air. The discharge port of the air tank 20 communicates with a plurality of air tank solenoid valves S1.

The liquid cleaning agent supply means 30 is filled with a liquid cleaning agent DTG and includes a vibrating bed 31, a cleaning agent vessel 33 seated on the vibrating bed 31 and one end connected to the solenoid valve S1 And the other end is positioned adjacent to the inner bottom surface of the cleaning agent container 33 and the other end is positioned adjacent to the cleaning agent container 33 exposed to the outside of the cleaning agent container 33, A water level sensor 35 provided inside the cleaning agent container 33 and a submerged pump 37 provided at the lower end of the cleaning agent feed pipe Pdo. The cleaning agent feed pipe Pdo, The upper end of the solenoid valve S2 is interlocked with the solenoid valve S2 for the cleaning agent.

This is because the lower end of the air supply pipe Pai can be expected to have a compressing effect of the liquid detergent DTG due to the high-pressure air so as to be located higher than the highest level of the liquid detergent DTG filled in the detergent container 33 . If the lower end of the air supply pipe Pai is positioned below the maximum level of the liquid detergent DTG, the liquid detergent DTG is aerated. The liquid detergent DTG filled in the cleaning agent container 33 and pressurized flows through the lower end of the cleaning agent feed pipe Pdo and is supplied to the foam gun 60 to be described later via the cleaning agent solenoid valve S2. Further, the submerged pump 37 is provided so as to additionally pump the liquid detergent (DTG) when the liquid detergent (DTG) is not preferably compressed and can not flow through the cleaning agent feed pipe (Pdo).

It is noted in advance that a regulator (regulator) capable of regulating the pressure of high-pressure air can be installed in the air supply pipe Pai for communicating the solenoid valve S1 for the air tank and the cleaning agent container 33 .

The liquid cleansing agent supply means 30 is provided with the vibration bed 31, the cleaning agent vessel 33, the water level sensor 35, the underwater pump 37 and the pipes Pai Pdo, as shown in Fig.

The foam gun 60 includes a cleaning agent inlet 61 communicating with the cleaning agent solenoid valve S2, a high pressure air inlet 63 communicating with the air compressor 10, a cleaning agent inlet 61 and a high pressure air inlet 63 And a nozzle 67 provided at the front end for mixing the cleaning agent DTG and the high pressure air Air to discharge the cleaning agent foam DF when the adjustment knob 65 is operated, . The nozzle 67 has a double structure composed of an inner skin 67a communicated with the cleaning agent inlet 61 and a skin 67b communicated with the high pressure air inlet 63. The inner skin 67a has a plurality of A high-pressure air inflow hole Ha is formed.

The air hammer ring 40 is interposed between the high pressure air solenoid valve S3 of the air compressor 10 and the high pressure air inlet 64 of the foam gun 60. [ When the adjustment handle 65 is operated by the user, the air hammer unit 40 senses the flow rate or flow rate of the high-pressure air, and interrupts the air supplied from the air compressor 10 by 5 to 3,000 times per second, 60 to the high-pressure air inflow port 64. Therefore, when the adjustment handle 65 of the foam gun 60 is operated, the high-pressure air is supplied at a rate of about 5 to 3,000 times per second, so that it is about 3 to 10 times higher than the supply of continuous high-pressure air It is smoothly mixed with the liquid detergent (DTG).

The control means COM controls the air compressor 10, the high-pressure air solenoid valve S3, the air tank solenoid valve S1, the cleaning agent solenoid valve S2, the water level sensor 35 and the underwater pump 37 . Here, the control means COM controls the cleaning agent solenoid valve S2, the high-pressure air solenoid valve S3 and the underwater pump 37 in accordance with the operation of the adjustment handle 65 of the foam gun 60. [

When the level of the liquid detergent DTG is lower than the reference level by the level sensor 35, the control means COM stops the operation of the underwater pump 37.

The operation of the present invention will now be described.

First, in the liquid detergent feeder 100 of the present invention, the air compressor 10 is operated by the control means COM so that the high pressure air is charged into the air tank 20, and the high pressure air of the air tank 20 is supplied to the cleaning agent And the liquid detergent (DTG) filled in the container 33 is pressurized.

When the user operates the control knob 65 of the foam gun 60, the cleaning agent solenoid valve S2 is opened to supply the liquid detergent DTG of the cleaning agent container 33 to the foam gun 60, At the same time, the high-pressure air solenoid valve S3 is opened and the air hammer device 40 is operated to cause the interrupted high-pressure air to flow into the foam gun 60 and mixed with the liquid detergent DTG, The bubble DF is discharged through the opening 67.

On the contrary, when the user operates the adjustment knob 65 to release the operation, the cleaning agent solenoid valve S2 is closed, the supply of the liquid cleaning agent DTG is stopped, and at the same time, the high-pressure air solenoid valve S3 is closed When the operation of the air hammer machine 40 is stopped, the foam DF discharged from the nozzle 67 of the foam gun 60 is no longer discharged.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
