 In order to achieve the above object, the supply device of the present invention comprises a tank for containing a liquid surfactant, a discharge port equipped with a stirring chamber for stirring the liquid surfactant and air, and the tank and the discharge port. A liquid surfactant supply path for communication and an air delivery device for communication with the discharge port via an air supply path are provided, and the liquid surfactant is pressure-fed to the discharge port by the head pressure of the liquid. It is characterized in that it is arranged at a height position.

[0005]

[Action]

 According to the above configuration, the liquid surfactant in the tank flows down in the liquid surfactant supply path by its head pressure and is pressure-fed to the discharge port, and the air supplied by the operation of the air feeding device is discharged. The liquid surfactant is mixed in the mouth, the liquid surfactant and air are stirred in a stirring chamber, and the foamed surfactant is discharged from the discharge port. Therefore, the device can be used permanently by replenishing the liquid surfactant in the tank appropriately. In addition, if the end of the liquid surfactant supply path is branched into multiple branches and the discharge ports are connected to the ends, respectively, and if each discharge port is connected to the air delivery device, a plurality of foamy surfactants will be formed. It is possible to discharge at a location. Furthermore, the liquid surfactant can be supplied to the discharge port without using a drive source, a compressed gas, a pressure vessel, or the like.

【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 air supply path, and 5 is air. A sending device, 6 is a control unit.

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. A switch b outputs a signal when the push button 7a is operated, and is electrically connected to the controller 6.

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 delivery device 5 is a device that forcibly sends air to the discharge port 2c through the air supply path 4, such as a manual or electric blower pump. In the present embodiment, an electric blower is used, and an electric power is supplied to the control unit 6. I am in contact with you. The air supply path 4 is formed by connecting the air delivery device 5 and the air introduction port 2b with a pipe 4 '. The pipe 4 ′ is branched into a plurality in the middle part, and the discharge nozzle 2 is connected to each of the 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.

The control unit 6 is configured to generate an output when an output signal from the switch b is input, and the air delivery device 5 operates upon receiving the output to supply air to the discharge port 2c. To do. The control unit 6 is provided on the installation surface C as shown in the figure, or is provided at another suitable place.

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 this time, the output signal from the switch b operates the air delivery device 5 to supply air to the discharge port 2c, the air and the liquid surfactant a are mixed in the flow path 2d, and the stirring chamber 9 It is agitated by the mesh 8. Therefore, the liquid surfactant a is discharged in a foam state.

When the liquid surface-active agent a is discharged in the form of foam in this way, the ejection force of the liquid surface-active agent a due to the water head pressure is too strong, and the liquid surface-active agent a hits the hand and scatters or flows 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 ′, or the output of the air delivery device can be adjusted, whereby the liquid surface active agent / air can be adjusted. It is also possible to make it possible to adjust the supply amount of the surfactant as desired so that the shape (fineness) of the surfactant discharged in the form of foam can be adjusted according to the preference of the user. Furthermore, desired functions other than those described above, for example, a function of displaying the remaining amount of the liquid surfactant a in the tank 1, a warning for preventing the overflow from the tank 1 when the liquid surfactant a is replenished Of course, it is optional to add a function and a function of displaying an abnormality when the liquid surfactant a or the air leaks due to the breakage of the tank 1, the discharge nozzle 2, the pipes 3'and 4 '.

[0017]

[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.
