【Example】

 Hereinafter, an embodiment of the supply device of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a tank containing a liquid surfactant (soap soap for hand washing in this embodiment) a, 2 is a discharge nozzle, 3 is a liquid surfactant supply path, 4 is an air supply path, 5 Indicates a pressurizing device.

The discharge nozzle 2 is installed on a counter surface provided in a washroom or a toilet, or on any other installation surface C, and has an inlet 2a for introducing a liquid surfactant a and air on the bottom thereof. The introduction port 2b is provided with a discharge port 2c at the tip, and a flow path 2d is provided inside for connecting the two introduction ports 2a and 2b to the discharge port 2c. Further, as shown in FIG. 2, an opening / closing valve 7 is provided in the middle of the flow path 2d, and a plurality of nets 8 are mounted in the discharge port 2c to stir the liquid surfactant a and air. The stirring chamber 9 is formed.

The opening / closing valve 7 may be an electric type or an electromagnetic type that opens for a certain period of time by an electric signal based on the detection of a hand by a human sensor such as a photoelectric sensor or the pressing operation of a touch switch. A manual type valve that opens mechanically while the button is pressed (or for a certain period of time) may be used, but in the illustrated example, a manual type opening / closing valve by operating the push button 7a is shown.

The tank 1 has an upper surface opened as shown in the figure, or has an upper surface closed with a replenishing port left, and an outlet 1a for the liquid surfactant a is opened at the bottom thereof. The outlet 1a and the inlet 2a of the discharge nozzle 2 are connected by a pipe 3 ', which forms a liquid surfactant supply path 3 that connects the tank 1 and the discharge port 2c. The pipe 3 ′ is branched into a plurality of parts in the middle, and the discharge nozzles 2 are connected to the respective branched ends. Further, the tank 1 has at least an appropriate interval h from the installation surface C, and more specifically, the interval at which the liquid surfactant a contained in the tank 1 is pumped by its head pressure to the discharge port 2c. It is arranged at an appropriate height position with h left.

The pressurizing device 5 is a device that sends compressed air to the discharge port 2c via the air supply path 4 and the air tank 5a, such as a compressor, a hydraulic (water pressure) cylinder, and the air supply path 4 is It is formed by connecting the pressurizing device 5 and the air introduction port 2b with a pipe 4 '. The air tank 5a is provided in the middle of the pipe 4 '. The pipe 4 ′ is branched into a plurality of pipes on the downstream side of the air tank 5 a, and the discharge nozzle 2 is connected to each of the branched ends. A safety valve 10 is provided on the pipe 4 ', and a check valve 11 is provided on the pipes 3'and 4'at appropriate positions.

A pressure sensor b is provided in the air tank 5 a, and the pressure sensor b and the pressure device 5 are electrically connected to the control unit 6. The control unit 6 receives the detection signal from the pressure sensor b, outputs a signal when the pressure inside the air tank 5a becomes lower than a predetermined pressure, and disappears the signal when the pressure becomes higher than the predetermined pressure. The pressurizing device 5 is configured to operate only while the signal from the control unit 6 is being input, so that the air tank 5a is constantly pressurized within a predetermined pressure range.

According to the above configuration, the liquid surfactant a in the tank 1 is pressure-fed to the flow path 2d of the discharge nozzle 2 by its head pressure, and is discharged from the discharge port 2c by pressing the push button 7a. .. At the same time, the compressed air supplied from the air tank 5a and the liquid surface-active agent a are mixed in the flow path 2d and stirred by the mesh body 8 in the stirring chamber 9. Therefore, the liquid surfactant a is discharged in a foam state.

As described above, when the liquid surfactant a is discharged in the form of foam, the ejection force of the liquid surfactant a due to the water head pressure or the compressed air pressure is too strong, and the liquid surfactant a may hit the hand and scatter or flow down. In addition to preventing this, a small amount of the liquid surfactant a can be used efficiently, which is effective in saving the liquid surfactant a.

In FIG. 3, in place of the mesh body 8 described above, small diameter portions 2c ′ are provided in the discharge port 2c at appropriate intervals, thereby forming the stirring chamber 9.

In the present invention, the discharge nozzle 2 is not limited to a plurality of discharge nozzles 2 as described above, and only one discharge nozzle 2 may be installed. The liquid surfactant a is not limited to water soap for hand washing. For example, shampoos, rinses, cosmetics, detergents used for various purposes, and other purposes such as household and commercial purposes, It can be arbitrarily selected according to.

Further, in the above embodiment, a flow rate adjusting valve or the like is provided in the middle of the pipes 3 ′ and 4 ′ so that the supply amount of the liquid surfactant / compressed air can be arbitrarily adjusted. The shape (fineness) of the foamed surfactant can be adjusted according to the user's preference. Furthermore, desired functions other than those described above, for example, a function for displaying the remaining amount of the liquid surfactant a in the tank 1 and a warning function for preventing the overflow from the tank 1 when the liquid surfactant a is replenished , The tank 1, the discharge nozzle 2, the pipes 3 ', 4', the air tank 5a, etc. are damaged, and it is of course optional to add a function to indicate an abnormality when the liquid surfactant a or compressed air leaks. Is.
