【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 an air supply means.

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 liquid surfactant a contained in the tank 1 is pressure-fed to the discharge port 2 c by its head pressure. It is arranged at an appropriate height position with a space h.

The air supply means 5 is a means for sending compressed air to the discharge port 2c via the air supply path 4 and the air tank 5a, for example, a compressor, a hydraulic (water pressure) cylinder, etc. The supply means 5 and the air introduction port 2b are connected by 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 nozzles 2 are connected to the respective branched ends. A safety valve 10 is provided in the pipe 4 ', and a check valve 11 is provided in the pipes 3'and 4'at appropriate positions. A pressure sensor b is provided in the air tank 5a, and the pressure sensor b and the air supply means 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 is below a predetermined pressure, and disappears when the pressure exceeds a predetermined pressure. The air supply means 5 is constructed so as to operate only while the signal from the control section 6 is being input, so that the inside of the air tank 5a is always 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 supply means 5 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 the present embodiment, the air supply means may be composed of only an air tank containing a compressed gas, in which case the air tank is replaceably connected to the base end of the pipe 4 '. .

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

FIG. 4 shows an example in which the above-mentioned air supply means 5 is constituted by an air delivery device, for example, a blower pump 5 '.

That is, in this embodiment, the blower pump 5 ′ and the switch c provided on the discharge nozzle 2 are electrically connected to the controller 6 ′, and the blower pump 5 ′ is operated by operating the switch c. As a result, air is supplied to the discharge port 2c, and as a result, a foamy surfactant is discharged from the discharge port 2c.

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 ′, or the output of the air supply means can be adjusted, whereby the liquid surface active agent / compression It is also possible to adjust the amount of air supply arbitrarily so that the shape (fineness) of the surfactant discharged in the form of foam 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 , Tank 1, discharge nozzle 2, pipes 3 ', 4', air tank 5a, etc. are damaged and liquid surfactant a, compressed air, etc. are leaked. It is optional.

[Effect of the device]

 Since the present invention is configured as described above, it is possible to foam various liquid surfactants used for detergents, cosmetics, and other household and business uses in the form of foam, and also to general households, offices, and other public It is possible to provide a liquid surfactant supply device that can be installed in a washroom or a toilet at a place for permanent use. Further, by branching the end of the liquid surfactant supply path into a plurality of ends, it is possible to discharge the foamy surface active agent at a plurality of locations using one tank. Furthermore, a drive source for supplying the liquid surfactant to the discharge port, a compressed gas, a pressure vessel, etc. are not required, and therefore the entire device can be made to have a simple structure.
