Description

[Detailed Description of the Invention] This invention relates to a foam generator that mixes a solution containing a surfactant, such as a washing liquid or a shaving solution, with air to form bubbles and then extract the bubbles.

Conventional foam generators manually squeeze the bottle to release air and contents at the same time to create foam, so only the amount commensurate with the squeeze can be taken out.

For this reason, the foam must be squeezed out from the bolt several times.

Moreover, the contents cannot be replaced without special equipment.

This idea uses the ejector action to mix liquid with air and make it bubble, easily generating bubbles.
Moreover, it is an object of the present invention to provide a bubble generator that can generate bubbles continuously and that allows easy replenishment of liquid.

This invention will be explained in detail below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes the main body of the bubble generator, and a battery chamber 1a for accommodating a power source battery 2 is formed in the base portion, and a lid 3 is detachably attached to the bottom portion.

Further, there is a machine room 1b above the battery room 1a, in which a motor 4, a transmission system 5, and a crank 6 are arranged.

A crank rod 7 provided on the crank 6 is connected to a diaphragm pump 8, and the diaphragm pump 8 has an air intake port 8a having a check valve.

The air chamber 1C in which the air intake port 8a is opened is communicated with the outside air through a through hole 9.

Further, the diaphragm pump 8 has an air discharge port 8b having a check valve, and an air jet nozzle 10 is communicated with this port.

The tip opening of this nozzle 10 is connected to the foam generator main body 1.
It faces the foam spout 11 formed at the tip.

A bubble chamber 12 is formed around the nozzle 10 and communicates with the bubble outlet 11.
The inside is filled with a foam having countless continuous pores, such as urethane foam or fired metal crystals.

Further, the tip of the siphon tube 13 is opened in the bubble chamber 12 .

The proximal end of the siphon tube 13 is opened in a bottle-shaped solution tank 14 which is removably screwed into the bubble generator main body 1.

If necessary, a bypass 15 is provided from the nozzle 10.
exits and communicates with the solution tank 14 via a space 16.

Then, pressurized air is brought into the tank 14.

In such a configuration, when the switch 17 is turned on and the motor 4 is driven by receiving power from the power supply battery 2, the diaphragm pump 8 is operated by the operation of the crank rod 7, and pressure is intermittently applied to the nozzle 10. send air.

For this reason, a high-speed air stream is emitted from the tip of the nozzle 10 and is ejected from the bubble outlet 11, so the bubble chamber 12 becomes under negative pressure due to the ejector effect.On the other hand, due to the force of the pressurized air from the bypass 15, The solution in 14 is in siphon tube 1
3 to the bubble chamber 12, where it passes through countless fine pores of the foam and is stirred and foamed while mixing with the high-speed air flow ejected from the nozzle.
1 to the outside.

In this embodiment, a diaphragm pump was used to supply air to the air jetting nozzle under pressure, but it goes without saying that a manual type or other pump type may be used.

As described in detail above, this device comprises a bubble chamber filled with foam around the air jet nozzle, and the siphon tube of the solution tank is opened in the bubble chamber to allow air to flow from the air jet nozzle. By ejecting the air stream, the solution is guided through the siphon tube to the bubble chamber by the ejector action, and mixed with air through the countless fine pores of the foam and agitated. The surfactant works more effectively and can easily generate bubbles.

In addition, you can generate as much bubbles as you need without the hassle of squeezing the bottle like in the past.
In addition, the practical effect is that the liquid can be easily refilled and can be used any number of times.
