Description

[Detailed Description of the Invention] This invention relates to a foam disc used in a foam cleaning device such as a foam facial cleansing device.

In recent years, foaming facial cleansers have come into wide use from the viewpoint of beauty and hygiene.

This foaming board guides compressed air discharged from a compressor to the bottom of a bowl-shaped washbasin filled with hot water, floats fine air bubbles from the foaming board placed there, and hits the floating bubbles on the face. This is intended to provide moderate stimulation to the skin.

In order to obtain fine air bubbles, a mesh layer made of a porous sintered material, wire mesh, woven fabric, or non-woven fabric is incorporated into the foam disk, but when using a face wash, Oily grime and other impurities released from the skin settle in the washbasin components and enter the foam board, and often adhere to the mesh layer and cause clogging. When the foaming disk was used again, some of its impurities were liberated and polluted the hot water, which was an inconvenience.

In addition, if the air bubbles eject from the mesh layer become clogged, the air bubbles will no longer hit the face, so it must be able to be cleaned at any time if it becomes clogged. Depending on the material, the mesh layer may stretch irregularly or be partially damaged due to direct exposure to water, so if the mesh layer is used frequently, it is necessary to frequently replace the mesh layer.

The purpose of this invention was to make it easier to clean and replace the mesh layer, in view of the fact that conventional foam disks were prone to clogging and were troublesome to disassemble. The foamed surface of the mesh layer is made of a thin plate of stainless steel so that it will not break even after repeated use. It is characterized in that the constituent parts can be disassembled and assembled by so-called bayonet coupling.

The 1-bayonet connection mentioned here means that a protrusion is formed on one side of two members, a locking piece that engages with the protrusion is formed on the other, and both members are rotated relative to each other. This is a coupling mode in which the locking piece and the locking piece are combined to lock both members together.

Hereinafter, this invention will be explained in detail with reference to embodiments shown in the accompanying drawings.

Figure 1 shows the disassembled state, and the foam board of this invention consists of an annular holder 1, a seal ring 2, and a mesh layer 3.
and a bottom plate 4.

The holder 1 is an annular body made of synthetic resin, and knobs 11 that protrude in the radial direction are integrally formed at appropriate positions on the periphery of the holder 1. Furthermore, knobs 11 are integrally formed at appropriate positions on the outer periphery of the annular holder 1. As shown in FIG. 2A, a plurality of bayonet coupling protrusions 15 are integrally formed.

Preferably, a stopper portion 150 is formed at one end of the protrusion 15, as shown in FIG. 2B.

The seal ring 2 is made of rubber and has a circular longitudinal section.

The mesh layer 3 has a foamed surface made of a disc made of stainless steel plate with a thickness of about 0.1 mm, and the foamed holes (not shown) are formed into ultra-fine holes with a diameter of about 0.2 mm by an etching process, that is, a chemical etching technique. It is formed with a pitch of .

This pitch should be determined according to the use of the foam board, but if it is set to 2 mm or less, especially in the case of a facial cleanser, a phenomenon will occur where air bubbles ejected from adjacent rear positions will combine and become larger. Therefore, in practice, it is desirable to set the thickness to 2 mm or more.

The bottom plate 4 is made of synthetic resin, and has a large diameter support part 46.
and a small-diameter support leg 44 formed integrally therewith,
It is a substantially disk-shaped body consisting of a bottom plate portion 42 and a connecting end 48.

This bottom plate portion 42 defines an air chamber formed by the back side of the mesh layer body 3 and the inner peripheral surface of the flat ring 3a reinforcing the outer peripheral portion of the mesh layer body 3 when bubbles are ejected, as will be described later.

Further, near the outer periphery of the bottom plate portion 42, an annular groove 43 for fitting the seal ring 2 is formed upward.

In addition, when the weight 5 is used, a flat weight is used, and a protrusion 49 for snap-coupling the weight 5 is provided at a predetermined position on the back surface of the bottom plate portion 42.

The annular holder 1
When attaching to the bottom plate 4, a locking piece 45 for locking the bayonet coupling projection 15 of the annular holder 1 is provided at a position corresponding to the projection 15 as shown in FIGS. 3A and 3B. There is.

Furthermore, a connecting end 48 is provided at an appropriate position on the bottom plate 4 and projects upward in the radial direction.

The connecting end 48 is connected to a hose or the like whose one end is connected to a compressed air source.

Reference numeral 47 denotes an air guide hole opened near the outer periphery of the bottom plate portion 42;
Compressed air sent into the bottom plate 4 from a hose connected to the connection end 48 is blown out from below onto the upper surface of the bottom plate part 42.

The support leg 44 has cutouts 44' that penetrate in the radial direction at various places.
is formed.

FIG. 4 shows the above member 1. 2. 3. 4 is a vertical cross-sectional side view of a foam board assembled with four members, and the method of assembling the four members will be explained below.

When assembling, first, the seal ring 2 is fitted into the annular groove 43 formed in the bottom plate part 42 of the bottom plate 4, and the mesh layer 3 is placed thereon.

Next, the annular holder 1 is attached to a protrusion 15 formed on its outer periphery.
is placed on the bottom board 4 so as to slightly avoid the bayonet coupling locking piece 45 formed on the bottom board 4 in the circumferential direction.

In this state, as shown in FIG. 5A, the annular holder 1
When the bottom plate 4 is relatively rotated, the protrusion 15 formed on the annular holder 1 fits into the recess on the lower surface of the locking piece 45 formed on the bottom plate 4, as shown in FIG.
and the bottom plate 4 are bayonet connected, and each member 1. 2.
3. Complete assembly of step 4.

When using the foam board of this invention, the compressed air supplied through the air guide holes 47 reaches the surface of the bottom plate 42 and the mesh layer 3.
enters the small air chamber formed by the lower surface of the
Bubbles smaller than the foam holes in the mesh layer 3 are ejected and float into the hot water spread over the washbasin member.

Although the embodiments have been described above, this invention is based on the annular holder 1.
, a mesh layer 3 made of a flat ring 3a having approximately the same diameter as the holder, fixed to a thin stainless steel plate with a large number of foamed holes; a seal ring 2; An annular groove 43 that protrudes and supports horizontally,
Further, the bottom plate is provided with a plurality of protrusions 45 on the inner peripheral surface for bayonet bonding the outer periphery of the annular holder 1, and an air guide hole 47 in the lower part for feeding air into the mesh layer from below. The introduction hole 4 is formed in a region surrounded by the bottom plate part 42 of the bottom plate 4, the mesh layer 3, its reinforcing flat ring 3a, and the seal ring 2.
Since an air chamber is formed in which the air sent from 7 is temporarily retained, the foaming board of this invention has the following effects.

(a) The annular holder 1 that sandwiches the mesh layer 3 and the bottom plate 4 are assembled by bayonet bonding.
No special tools or techniques are required for assembly, making assembly and disassembly easier.

Therefore, when the mesh layer 3 becomes dirty, by removing the bayonet connection, the mesh layer 3 as well as every corner of the bottom plate 4 can be washed extremely easily. Easy to manage.

This is a particularly noteworthy advantage for products intended for general consumers, such as facial cleansers.

(b) By adopting the bayonet connection, there is no need for fastening fittings such as screws for assembly, and together with the fact that the mesh layer 3 is formed of a stainless steel thin plate, there is no rusting. The idea not only reduces the number of parts, but also
It has excellent hygienic effects and can reduce product costs.

(C) Since the mesh layer 3 is sandwiched between the seal ring 2, the annular holder 1 and the bottom plate 4 which are mutually bayonet-bonded, the compressed air sent from the air guide hole 47 toward the air chamber is Will not leak.

(d) The mesh layer body 3 is provided with a flat ring 3a for reinforcing the outer periphery, and the ring is attached to the seal ring 2.
Since this is also a sealed surface, even if the mesh layer body 3 is extremely thin, there will be no leakage of air from the sealed surface.

(e) Other members 1 including the mesh layer 3. 2.
4 are independent from each other, so when some parts are damaged, only those parts need to be replaced, making replacement costs cheaper than conventional ones.
