Description

Detailed Description of the Invention [Industrial Application Field] This invention relates to a shower head that can spray and disperse a water stream or a steam/water mixed stream by manually switching the flow as desired. Its main feature is that it has the function of cleaning bubbles using air flow.

[Conventional technology and problems to be solved]

Conventionally, a bubble face wash device has been provided in which water or hot water is poured into a water container and compressed air from an air compressor is supplied from the bottom of the water container through a bubble dispersion plate to generate bubbles and wash the face. This is common knowledge.

However, with this type of bubble face wash, it is necessary to immerse the entire face in the water, making it difficult to breathe while washing the face, and the user sometimes has to lift their face out of the water to catch their breath and then immerse their face in the water again. Therefore, it takes time to wash the face, and it is also mentally painful. In addition, since a power source is used to operate the air compressor, there is a risk of electric shock, and dirt from the face, sebum, and other impurities may fall off in the water in the water container or into the bath, and air bubbles may stir up the water flow. As a result, these filth may re-adhere to the skin, mouth, eyes, nose, etc., resulting in a feeling of uncleanness.
Furthermore, some ingredients of cosmetics applied to the face and sebum have a foam suppressing effect, and the bubble diameter increases during face washing, making it difficult to wash the face with stable microfoam.

Moreover, cleaning and drying the water container is time-consuming.
In some cases, bacteria such as mold may grow on the bubble dispersion disk, making it unclean.

The present invention is devised to realize a bubble cleaning device that improves the above-mentioned drawbacks by using an air-water mixed flow jetting rod,
Furthermore, the present invention provides a spouting rod that emits water and a mixed flow of air and water and also has the function of a shower using a normal water dispersion flow.

[Means to solve the problem]

That is, according to the spout rod of the present invention, the negative pressure effect when water or hot water is spouted from the nozzle is used to suction and mix air to create a mixed flow of air and water, which can be applied to the face, head, and other parts of the body. It is designed to perform bubble cleaning, stimulation, and pine surge by pouring water into the water, and is equipped with a hot water dispersion plate with multiple small holes, and a hot water spouting nozzle part that spouts a stream of water or hot water, and the hot water dispersion nozzle. A steam/water spouting nozzle section is provided at a position opposite to the steam/water spouting nozzle section and spouting a steam/water mixed flow of water or hot water and air; A spouting rod for a water flow and a mixed flow of air and water, which is used by being connected to a water or hot water supply pipe, and is equipped with a pair of water supply channels for supplying water and a switch for switching between the pair of water supply channels. , the steam/water spouting nozzle section includes a hot/water dispersion nozzle including a hot/water spouting nozzle and a steam/water mixed flow forming chamber formed at an outlet of the hot/water spouting nozzle; An air suction hole is provided around the air-water mixed flow forming chamber to allow air to flow into the air-water mixed flow forming chamber due to the low-pressure effect of the high-speed jetting hot water flow. a rectifying plate with a plurality of small holes that rectify the flow of air and promote subdivision of air bubbles; and an air intake amount adjustment device that adjusts the amount of air sucked into the water or hot water and the diameter of the bubbles by varying the opening area of the air suction holes. and a means for controlling the spouting rod of the water flow and the air/water mixture flow formed by the manual switch that opens either one of the pair of water supply channels. This is what we provide. This spout of a mixed flow of water and air does not require an air compressor or water container, and it also allows you to wash your face while breathing, concentrating on any part of your body and constantly producing constant air bubbles. It is extremely hygienic because it can be cleaned with a fresh air-water mixed flow.

Furthermore, by changing the distance between the cleaning portion and the steam/water mixed flow disperser, an appropriate steam/water mixed flow can be directed.

Currently, most households use a well-known shower head, and by attaching the above-mentioned air-water mixed flow distributor to this shower head, it can be used as either a regular shower or a steam-water mixed flow separator.
This makes it possible to create a cleaning device that is extremely versatile, convenient, safe, and inexpensive.

By adjusting the amount of suction air, the bubble diameter changes (the smaller the suction amount, the smaller the bubble diameter, and the larger the suction amount, the larger the bubble diameter). Depending on the purpose, the size of the bubbles can be selected. That is, a small bubble size can be used for cleaning skin wrinkles and areas with small pores, and a large bubble size can be used for cleaning, stimulating, and pine surges on the skin surface.

Further, when the air-water mixed flow is spouted upward, a water flow prevention disc is provided to prevent falling water from being sucked into the air suction path due to the negative pressure effect of the nozzle and impairing free suction of air. Therefore, even if the spouting rod of the present invention is turned upward and used for, for example, washing the face, the user can effectively bathe in the mixed flow of air and water.

Next, the present invention will be explained based on embodiments shown in the drawings.

〔Example〕

In the figure, reference numeral 1 denotes a handle having a supply path for hot water W, one of which is screwed to, for example, a flexible pipe P, and the other to a head 2 via a packing 3. The head 2 has a water supply channel Q for spraying and dispersing water or hot water and a water supply channel R for spraying and dispersing a mixed flow of air and water.
By manually pressing the button 4, a piston 5 integrated with the button 4 is moved to open either the water supply channels Q or R.

After inserting the switch S into the head 2, tighten the screw 6.
This prevents it from slipping out.

The surface F ₁ or F ₂ of the piston 5 is always pressed against the closed water supply channel side by water pressure on the open water supply channel side where hot water is supplied. Reference numeral 7 denotes an ordinary hot water distribution plate having a plurality of small holes, and is screwed onto the head 2 via a backing 8.

A hot water dispersing nozzle 9 having a plurality of nozzles N is provided at a position of 180 degrees with respect to the long axis of the main spout rod, facing the hot water dispersing plate 7, and is screwed onto the head 2 by a fixing ring 11 via a packing 10. has been done. A plurality of internal air suction holes H _i are distributed in the radial direction of the hot water distribution nozzle 9 . Due to the hydrodynamic low-pressure effect caused by the high-speed jetting flow of hot water from the nozzle N, air A is sucked through the plurality of external air suction holes H _p and into the hot water jetting flow K from the internal air suction holes H _i . The water is suctioned into bubbles, and a steam/water mixed flow is generated in the steam/water mixing wave forming chamber 32 provided in the hot/water dispersion nozzle 9.
