Description

[Detailed explanation of the invention] This invention, for example, generates air bubbles in the bathtub to clean the legs, waist, etc.
The present invention relates to a bubble generating device used in a bubble massager in a bath to massage various parts of the human body to promote recovery from fatigue, a bubble facial cleansing device to remove dirt from the face, and a light massage to various parts of the face.

Conventionally, this type of bubble generator, taking a facial cleansing device as an example, connects an appropriate pump to the air chamber of the bubble generator provided at the bottom of a container 100 through a connecting pipe 102, as shown in FIGS. 6A, B, and C. Air is sent from the device, and the air is ejected into the water through small holes drilled on the surface of the bubble generator to generate bubbles.

By the way, in the example shown in FIG. 6A, a bubble plate 104 having a large number of air ejection holes on its surface is adhered along the inner wall of the container 100, and an air chamber 106 is defined in the lower part.

In this case, manufacturing is easy and costs can be reduced, but even if the inside of the air chamber 106 becomes dirty, it cannot be cleaned because the bubble plate 104 cannot be removed, which is extremely unsanitary.

Next, in the example shown in FIG. 6B, the bubble generator 112 is formed into a box surrounded by a bubble generator plate 108 having a large number of air ejection holes on the top surface, and an air chamber 110 is defined inside the box. However, since the air chamber 110 must be mechanically sealed sufficiently, it requires consideration in manufacturing, and furthermore, the air chamber 110 cannot be cleaned as in the example shown in FIG. It's hygienic.

Further, in the example shown in FIG. 6C, a seal ring 116 is fitted between the periphery of a foam board 114 provided with a large number of air ejection holes and the inner wall of the container 100, and the center of the foam board 114 is secured to the container with a stopper. Since the structure is such that the air chamber 118 is formed at the bottom of the foam board 114 by fixing it to a support provided protruding from the bottom surface of the foam board 114, it is easy to remove the foam board 114 and clean the air chamber 118. If the container is deformed due to distortion or impact during molding, it may become impossible to seal, or the seal ring 1 may become damaged due to temperature changes during use.
6 expands and contracts, and sometimes hardens, which is not always satisfactory.

In view of the various disadvantages of conventional bubble generators as mentioned above, the present invention has a removable bubble generating plate, the interior can be easily cleaned, the structure is simple, and the need for sealing is eliminated. This bubble generating device was devised with the aim of obtaining a bubble generating device that can be eliminated and reduce manufacturing costs.

Next, an embodiment will be described in which the bubble generating device according to the present invention is applied to a face wash device shown in FIGS. 1 to 5 of the drawings.

In FIG. 1, 10 is a face-washing container filled with water W, 12 is a bottom plate of the container, and 14 is a column formed in the center of the bottom plate 12. This column 14 has many fine air blowing holes 2.
A bottomless bubble generator 20 is integrally formed with a foam plate 18 formed by penetrating the foam plate 4 through the upper and lower surfaces thereof, and a peripheral wall 16 provided downward along the periphery of the foam plate 18. ing.

Reference numeral 26 denotes a nozzle formed near the bottom of the face-washing container 10 toward the centripetal direction of the container, and the tip of the nozzle 26 penetrates the peripheral wall 16 with the circumference sealed with a seal ring 28 to form the foam board 18. A hose 30 is opened at the bottom and is connected to the rear end of the hose 30, which is connected to a compressed air supply source (not shown).

Therefore, the size and number of the air jet holes 24 and the nozzles 26
The size of the foam board 18 and the pressure of the supplied air are adjusted so that a sufficient air pocket 32 is formed on the underside of the foam board 18 during use.

Next, how to use the above embodiment shown in FIG. 1 will be explained.

When air is sent from the nozzle 26 during use, an air pocket 32 is formed inside the bubble generator 20, that is, on the bottom surface of the foam board 18, and the air accumulated in this air pocket 32 is transferred to the bubble board 18.
The air passing through the air outlet 24 generates air bubbles in the water.

Note that the position of the lower edge 16a of the peripheral wall 16 is from a position deeper than the position of the air jet holes 26;
Therefore, the air in the air pocket 32 does not pass through the lower edge 16a, and the air in the air outlet 2
From step 6, bubbles are generated smoothly.

FIG. 3 shows a second embodiment, in which a partition wall 34. FIG. 5 shows a third embodiment in which the partition walls 36 are arranged radially.

According to the second and third embodiments, from the nozzle 26 to the foam plate 2
The air that enters the air pocket 32 at zero is subjected to resistance from the partition walls 34 and 36, so that the air pressure inside the bubble generator 22 is not biased such that it is stronger on the side closer to the nozzle 26, and the air is uniform and normal in each part. A pool 32 is formed, and the ripples and unevenness as shown in FIG. 2 are eliminated, and uniform bubbles are generated from the entire surface of the foam board 18.

Although the embodiments have been described above, the present invention provides a bubble generating device in which a bubble plate with a large number of air jet holes penetrating the upper and lower surfaces is removably attached to the bottom of the container. Since the wall for the air pocket is made of rawhide is protruded downward, there is no need to form the air pocket separately in the box body as in the past, and there is no need for sealing at all, resulting in a simple structure. , can be produced at low cost.

Furthermore, by removing the bubble generator, the entire device can be easily cleaned, making it extremely sanitary and highly practical.
