Description

[Detailed explanation of the invention] This invention generates air bubbles in the washing water, and uses the convection action of the washing water accompanying the generation of air bubbles, and the action of ultrasonic waves generated at the moment the air bubbles are generated and the moment the air bubbles break. The present invention relates to a bubble generator that uses vibration waves to effectively wash the face.

Devices are known that produce a pine surge effect by stimulating the skin and promoting blood circulation by the synergistic energy of vigorously ejected air bubbles and water flow, and an example of such devices can be found in Japanese Utility Model Application Publication No. 49-4837.

Conventional devices of this kind, including the facial cleansing bubble generator shown in the above-mentioned Japanese Utility Model Publication No. 49-4837, have air ejection holes formed over the entire blowing surface of the foam 102. As a result, the bubbles 104 become concentrated in the center as shown in FIG. The surface becomes rippled, which sometimes overflows from around the face-washing container 100, and also irritates the nose during face-washing, thereby interfering with face-washing.

Therefore, when the jet surface is formed in the center of the face-washing container, the bubble action is biased towards the center of the face, resulting in a drawback that the face-cleansing effect of the bubbles does not reach every corner of the face.

In addition, in the previous model, the bubble generating part was built into the bottom of the face wash container, so the way the bubbles were generated was constant. The drawback was that you could not wash your face according to your preferred conditions.

In view of the above-mentioned drawbacks of conventional facial cleansing bubble generators, the present invention has been developed to create bubbles that are strong enough to suit the user's preference and rise in a cylindrical shape to provide a comfortable touch to the skin. It creates air bubbles, prevents excessive ripples on the water surface, and generates air bubbles over the entire surface of the face-wash container to achieve an effective cleaning effect. This invention was devised with the aim of reducing irritation to the nose, and examples of this invention are shown below in Figures 1, 2 and 3.
This will be explained based on Figure B.

Figure 1 is an explanatory diagram showing the state of bubble generation during use, Figure 2 is a vertical cross-sectional front view of the bubble generator of the present invention, and Figure 3B shows the convection of cleaning water and bubble groups in the present invention. In the explanatory diagram, 10 is a face-washing container filled with washing water 12, 18 is a bubble-generating plate fixed to the bottom of the face-washing container 10 with a stator 3B described later, and this bubble-generating plate 14 is made by combining a top plate 26 and a bottom plate 22 It is a hollow body having a non-perforated part formed in a relatively wide central part of the top plate 26, and a fumarole surface with a large number of air ejection holes 24 bored around the non-perforated part.

The bottom plate 22 is removably fixed to the seating surfaces 34 and 36 of the top plate 26.

Note that although the seating surfaces 34 and 36 are not provided with seals for fluid tightness, seals may be provided if there is a large amount of air leakage from the seating surfaces 34 and 36.

An annular air chamber 28 is formed inside the bubble generating plate 18 so as to be positioned directly below the blowing surface, that is, the air blowing holes 24, and the lower surface of the hole-free portion is in surface contact with the upper surface of the bottom plate 22.

One end of the hose 30 is connected from above to the annular air chamber 28 via a nipple 32, and the other end is connected to a suitable compressed air supply source.

Reference numeral 16 denotes a protrusion provided at the center of the bottom of the face-washing container 10. The protrusion 16 has a vertical hole 20 that opens upward, and a conical shape is provided at the bottom of the protrusion 16 to stabilize the bubble generating plate 18. A seat surface 14 is formed.

A hole for inserting the projection 16 is formed vertically through the center of the holeless portion of the bubble generating plate 18.

Reference numeral 38 denotes a stator with a knob, which has a presser flange 42 of the bubble generating plate 18 above, and an opening pin 44 elastically engaged with the vertical hole 20 of the protrusion 16 at the lower part. If you push it in the most forcefully, you can fix the bubble generation plate 18 in the lowest state at the bottom of the face-wash container 10, and if you adjust the way you push the stator 38 so that it stays above the state shown in FIG. When the face-washing container 10 is filled with cleansing water 12, the bubble-generating plate 18 can be floated until it hits the presser collar 42.

Next, the operation of this embodiment will be explained.

The bubble generating plate 18 is inserted into the bottom projection 16 of the face-washing container 10, and then the stator 38 is fitted into the vertical hole 20 of the projection 16.

Since the fitting portion of the stator 38 into the vertical hole 20 is formed by an opening pin 44, when the opening pin 44 is fitted into the vertical hole 20, the stator 38 is pushed onto the protrusion 16 by the elastic force of the pin. Firmly fixed.

Next, an appropriate amount of cleansing water 12 is filled into the face cleansing container 10.

In this case, if the fixed position of the stator 38 is the deepest at the bottom, the top surface of the bubble generating plate 18 is held down by the presser flange 42 of the stator 38, as shown in FIG.
However, if the fixed position of the stator 38 is shallow, the air bubble generation plate 18
floats up until it hits the presser collar 42 due to buoyancy, so when air is started to be supplied to the annular air chamber 28 at this time, the compressed air enters the air chamber 28 along the inner circumferential wall surface of the annular air chamber 28 and fills the hole. Air bubbles are ejected in a ring shape from the air ejection holes 24 surrounding the blank part, and a group of air bubbles 4 is generated thereby.
0 rises in a cylindrical manner.

Therefore, when the stator 3B is pinched and the stator 38 is opened and moved up and down against the elastic force of the pin 44, the bubble generation plate 18 moves up and down depending on the up and down movement of the stator 38, and accordingly, Since the convection state of the bubble group 40 changes, the stator 38 is fixed after adjusting the way the bubble flow and the washing water flow hit the face as desired.

When air is ejected from the air ejection holes 24 in this way, as shown in FIG. A group of bubbles 114 with a strength suitable for the skin is placed directly above the
This prevents the bubbles from being concentrated in the center, which is the case with conventional bubble generators.

At this time, there appears to be a part in the central part 118 of the washing water where no air bubbles are generated, but as mentioned above, the group of air bubbles 114 flows in the centripetal direction in this part, so it does not irritate the nostrils. disappear, and this cylindrical bubble group 1
14, the convection of the cleansing water divided into the centripetal direction and the radial direction of the face-washing container 110 acts to reduce ripples on the surface of the cleansing water.

As above, the present invention has been explained based on the embodiments, but the present invention differs from the face-wash container and the bubble-generating plate formed separately from the same container, and includes a protrusion at the center of the bottom of the face-wash container.
The protrusion is provided with a hole that opens upward, while the bubble generating plate has a non-perforated part formed in the center of the upper surface, and a hole inserted into the protrusion in the center of the non-perforated part, and,
A fumarole surface is formed around the insertion hole with a large number of air ejection holes perforated on one side, and an annular air chamber is formed inside by being located directly below the fumarole surface. It has a structure in which the base end of a hose leading to a compressed air supply source can be connected from above to the inner circumferential wall surface, and furthermore, the face-washing container and the bubble-forming plate have a presser flange for the bubble-generating plate on the upper part, and the base end of the hose leading to the compressed air supply source can be connected from above. Since the stator is detachably connected using a stator with a knob having an opening pin that elastically engages with the hole of the projection, at least the following effects can be achieved.

First, because the air chamber is formed in an annular shape inside the foaming disk, air bubbles rise up in the washing water in a cylindrical shape, and these air bubbles are caused to convect in both the centripetal and radial directions together with the washing water, and are brought close to the water surface. Generates minute vibration waves with even strength and weakness.

Therefore, if the bubble generator of the present invention is used, the minute vibration waves generated by the action of ultrasonic waves generated at the moment when bubbles are generated or burst will uniformly spread to the wash water in the face wash container, resulting in a cleansing effect. can be significantly improved.

Moreover, the bubble foaming board can be attached and detached from the face-washing container using a stator, and the convection of the air bubbles can be changed according to the user's preference depending on the fixed position of the stator. Since the flow of water is divided into both centripetal and radial directions by the cylindrical bubbles, there is less irritation to the face during use, and the ripples on the surface of the washing water are smaller than before, making the washing water more efficient. Even if you put a little too much into the face-washing container, it will not overflow from the container, and furthermore, you will not have to worry about inadvertently getting your hair wet while washing your face.

Furthermore, since the bubble group is formed in a cylindrical shape in the washing water, the bubbles do not hit the nose from directly below, but from an oblique direction.

Therefore, the nostrils are not tickled and the nose is not irritated unnecessarily, so there is no difficulty in breathing during use.

Further, since the bubble generating plate can be easily removed by detaching the stator from the face washing container, the bubble generating plate can also be easily washed, and there is an effect that the cleaning can be performed in a clean state at any time.
