[Problems to be solved by the device]

 The above-mentioned conventional supply device is a so-called disposable device that becomes unusable when the encapsulated liquid surfactant and compressed gas are exhausted, and is used permanently in, for example, the washroom / toilet of an ordinary household or office. It was not suitable for. The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to be capable of foaming various liquid surfactants used for detergents, cosmetics, and other household and commercial uses. The purpose of the present invention is to provide a supply device that can be installed for permanent use in a washroom / toilet in an ordinary home, office, or other public place.

[0004]

[Means for Solving the Problems]

 To achieve the above object, the supply device of the present invention comprises a liquid tank containing a liquid surfactant, an air tank containing a pressurized gas, and a stirring chamber for stirring the liquid surfactant and the pressurized gas. The liquid tank is connected to the liquid tank via the liquid surfactant supply path and to the air tank via the air supply path. It is characterized in that it is arranged at a height position where the agent is pumped to the discharge port by its head pressure.

[0005]

[Action]

 According to the above configuration, the liquid surfactant in the liquid tank flows down in the liquid surfactant supply path due to its head pressure and is pumped to the discharge port, and the pressurized gas supplied from the air tank is also supplied. Is mixed with the liquid surfactant in the discharge port, and the liquid surfactant and the pressurized gas are stirred in the stirring chamber to discharge the foamy surfactant from the discharge port. Therefore, it is possible to permanently use the device by appropriately replenishing the liquid surfactant in the liquid tank and appropriately replacing the air tank. Also, if the end of the liquid surfactant supply path is branched into multiple parts and the discharge ports are connected to the ends of each, and each discharge port is connected to the air tank, the foamy surfactant can be applied to multiple locations. It is possible to discharge with. Furthermore, the liquid surfactant can be supplied to the discharge port without using a drive source, a compressed gas, a pressure vessel, etc., and a drive source for supplying air to the discharge port is not required.

【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 liquid 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 route, 4 air supply route, 5 Indicates an air tank.

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 installed in the discharge port 2c so that the liquid surfactant a and the pressurized gas are discharged. A stirring chamber 9 for stirring 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.

As shown in the figure, the liquid tank 1 is formed by opening the upper surface or closing the upper surface leaving a replenishing port, and an opening 1a for taking out 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 ', whereby a liquid surfactant supply path 3 that connects the liquid tank 1 and the discharge port 2c is formed. 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 liquid tank 1 is at least appropriately spaced apart from the installation surface C by an appropriate distance h, and more specifically, the liquid surfactant a contained in the liquid tank 1 is pumped to the discharge port 2 c by its head pressure. It is arranged at an appropriate height position with a space h.

The air tank 5 is a pressure-resistant container containing a pressurized gas (compressed gas, compressed air, etc.), for example, a pressurized cylinder, and sends the pressurized gas to the discharge port 2 c via the air supply path 4. The air tank 5 is replaceably connected to the base end of the air supply path 4 (base end of the pipe 4 '). The air supply path 4 is formed by connecting the air tank 5 and the air introduction port 2b with a pipe 4 ', and the pipe 4'is branched into a plurality of portions in the middle, and the discharge nozzles 2 are connected to the respective branched ends. .. An opening / closing valve 10, a safety valve 11 and the like are provided in the pipe 4 ', and a check valve 12 is appropriately provided in the pipes 3'and 4'.

According to the above configuration, the liquid surfactant a in the liquid tank 1 is pressure-fed to the flow path 2d of the discharge nozzle 2 by its head pressure, and the push button 7a is pushed to the discharge port 2c. Is ejected. At the same time, the pressurized gas supplied from the air tank 5 and the liquid surface-active agent a are mixed in the flow path 2d and stirred by the net 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 pressurized gas pressure is too strong, and the liquid surfactant a is splashed by falling into the hand. Not only is it possible to effectively prevent the use of a small amount of the liquid surfactant a, but it is also 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 ', 4', so that the supply amount of the liquid surfactant / pressurized gas can be arbitrarily adjusted. It is also possible to adjust the shape (fineness of the texture) of the foamed surface-active agent to 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 liquid tank 1 and a function for preventing overflow from the liquid tank 1 when replenishing the liquid surfactant a A warning function and a function to display an abnormality when liquid surfactant a or pressurized gas leaks due to damage to liquid tank 1, discharge nozzle 2, piping 3 ', 4', air tank 5, etc. are added. Of course, it is arbitrary.
