Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a foaming device for generating bubbles in a bathtub, and particularly to a foaming device disposed within the bathtub.

[Conventional technology]

Conventionally, this type of foaming device has been constructed by making countless small holes on the surface of the flat foaming device made of synthetic resin and attaching a pressure air blowing pipe to one side, and the foaming device based on the invention of the present inventor. A foam plate with numerous small holes as described in Utility Model Application No. 117048/1983 is attached to the open top surface of the foamer body, the tip of the blow pipe is positioned in the center of the body, and There are some with multiple holes formed on the surface.

[Problems to be solved by the invention] In the conventional foaming device described above, water is allowed to flow into the foaming device through numerous small holes drilled in the surface of the foaming device, and the foaming device is immersed in the bottom of the bathtub. Since the diameter of the countless small holes drilled on the surface of the foamer is less than 1 mm, there is a problem in that it takes a very long time to sink the foamer to the bottom of the bathtub.
It is also possible to remove the connecting pipe connected to the compressor from the blower pipe of the foamer, allow water to flow in from the mouth of the blower pipe, and submerge the foamer in a bathtub. , there are some troublesome problems to install.

[Means for solving problems]

The object of the present invention is to solve the above-mentioned problems of the prior art and provide a foaming device that can be quickly and easily immersed in the bottom of a bathtub.

Therefore, the present invention achieves the above-mentioned object by forming a water inlet in the main body of the foamer and providing an on-off valve in the water inlet.

〔Example〕

In the figure, the foamer according to the present invention has two legs on the bottom.
The pillar 4 with the tip of the air pipe 3 introduced into the center is made to stand upright, and a foam plate 7 having numerous small holes 6 is fitted into the upper expansion step 5 with a rubber seal in a liquid-tight manner. It consists of a foaming device body 1 in the shape of a circular flat case, on which protective rods 8 are attached radially, and a plurality of small holes 6' are formed in the peripheral wall surface.

A water inlet A is formed on the bottom of the foamer main body 1, and an on-off valve B is attached to the water inlet A. Open/close valve B
has an outer annular plate 10 and an inner annular plate 11 in the shape of 〓 that protrude from the water inlet A to the inside of the main body 1, and the outer annular plate 10 and the inner annular plate 11 have a constant interval between their circular upper surfaces. They are superimposed on each other and attached to the bottom surface of the main body 1 in a liquid-tight manner. The outer annular plate 10 has a guide cylindrical body 12 attached to the center of its circular upper surface, and has a flow port 13 on its outer periphery.
has a communication hole 14 bored in the center of its circular top surface. An operation bolt 16 having a cylindrical sliding member 15 is fitted into the guide cylindrical body 12 attached to the outer annular plate 10 and protrudes from the communication hole 14 formed in the inner annular plate 11, and the protruding operation bolt 16 has a communication hole. 1
The pressing ring 17 having a diameter smaller than that of the cylindrical sliding member 1
Further, a circular rubber ring 18 having a diameter larger than that of the communication hole 14 is attached to the tip of the rubber ring 18 with a nut 20 via a reinforcing ring 19 so as to abut against the pressing ring 17. A helical spring 22 is disposed around the guide cylinder 12 between the retaining ring 21 attached to the head of the operating bolt 16 and the upper surface of the outer annular plate 10 . In order to seal the inner annular plate 14, the rubber ring 18 is urged to come into pressure contact with the upper surface of the inner annular plate 11 via an operating bolt 16. Therefore, a gap is formed between the retaining ring 21 and the lower end of the guide cylinder 12, and the cylindrical sliding member is moved together with the operating bolt 16 against the spring 21 until the retainer ring 20 comes into contact with the lower end of the guide cylinder 12. 15 can be pushed upwards along the guide cylinder 12.

A blower pipe 3 introduced from the peripheral wall of the main body 1 to the support 4
A universal nipple 9 for attaching a connecting pipe connected to the compressor is attached to the base of the support column 3, and a plurality of communication holes 10 are bored in the circumferential surface of the support column 3. Further, a container C in which a radon generator is placed is attached to the lower surface of the main body.

[Effect]

When the foamer of the present invention, which is equipped with a connecting pipe connected to the compressor, is immersed in a bathtub, the retaining ring 2
1 comes into contact with the lower end of the guide cylinder 12 by pressing the operating bolt 16 upward against the spring 21.
The cylindrical sliding member 15 of the operating bolt 16 rises along the guide cylinder 12, the pressing ring 17 lifts the rubber ring 18 to the position shown by the two-dot chain line in FIG. away from the circular top surface of
Valve B opens. If the valve B is inserted into the bathtub in an open state, that is, with the operating bolt 16 pushed up, water will pass through the communication port 13 of the outer annular plate 10 and the communication hole 14 of the inner annular plate 11, and will flow between the rubber ring 18 and the inner annular plate. Board 11
flows between the upper surface of the foamer and enters the foamer main body 1,
Since the small holes 6 and 7 formed in the main body 1 function to discharge air within the main body 1, water quickly enters the main body 1. If valve B is removed from water inlet A, water inlet A
also acts as a cleaning opening that can clean the inside of the main body 1.

〔Effect of the invention〕

Just by pushing up the operating bolt 16, the valve B can be opened and water can flow into the foamer body 1, so the foamer body 1 can be quickly and easily immersed in the bathtub and connected to the compressor. There is no need to worry about removing and installing connected pipes.
