The present invention relates to a nozzle apparatus used for the massage massage.

It is known that the shower device installed in the bathroom converts the ejection state into two by turning the shower head in the right direction, and is commonly used for shower and massage massage.

However, in the conventional shower apparatus, since a sufficient fractionation massage effect is not expected, a means of incorporating a means for mixing air into the hot water to eject a mixture of the hot water and air (in this specification, the classification of the mixed fluid is referred to as jet classification). It is becoming practical by the inventors.

However, converting jets into manual operation of the showerhead is cumbersome, and because jet jets are very powerful compared to showers in generating jet jets, there are a number of risks associated with direct jetting or into the jet. Despite the accompanying problems, there was a problem that could not clearly call attention to the users.

The present invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to change the ejection state of the hot water as the operation of hanging and removing the nozzle body. An object of the present invention is to provide a nozzle apparatus in which a classification according to a taste can be obtained safely by being performed within.

The chamber 153 is formed, and a jet blowing hole 155 is formed in the center of the bowl-shaped bottom 154 of the valve nozzle 152.

An air passage 156 is formed in the first partition wall 130 to the air introduction hose 128, and the air from the air introduction hose 128 passes through the air introduction passage 128. 153).

Next, the operation of the above embodiment will be described.

The hot water supplied from the pump P passes through the hose 125 and enters the barrel hole 122a of the holding cylinder 122.

At this time, when the engaging portion 118 of the switching lever 144 is in the rotational position of jet jet flow, the inlet side of the switching passage 109 is connected to the through hole 122a as shown in FIG. Since the outlet side of the () is connected to the flow channel 145, the hot water flows into the gas-liquid mixing chamber 153 through the flow path 145 from the switching passage 109 and is jetted out through the jet jet hole 155.

At this time, the air introduced into the air passage 156 is sucked into the gas-liquid mixing chamber 153 by the ejector effect, so that the hot water and the air are mixed in the gas-liquid mixing chamber 153, and the mixed liquid is jet-jetted. It is ejected from the blowing hole 155.

Next, when the engaging portion 118 of the switching lever 114 is pressed to adjust the lever 114 to the operation position of the shower jet flow, the inlet side of the flow path 145 is the switching valve 111 as shown in FIG. Is closed by

On the other hand, the outlet side of the switching passage 109 is connected to the valve hole 129.

As a result, the hot water from the pump passes in the order of the valve hole 129, the passage space 119, the through hole 138, the water supply inlet chamber 134, and the passages 136, 137, and the van vehicle accommodation chamber 135. Is sprayed on.

The vane 143 receives the jet water and the vanes 142 rotates, and the shield plate 144 rotates with the rotation of the vanes 142.

Thus, for example, when the shower jet holes 141b and 141c are closed by the shielding plate 144, the shower jet is ejected from the open shower jet hole group 141a. The jetting hole groups 141a and 141c are closed, and the shower classification is ejected from the shower jetting hole 141b.

By rotating the vane 142 in this way, the hot water is spewed out from the shower jet hole groups 141a, 141b, and 141c sequentially or showered (hereinafter referred to as intermittent shower classification), which is discharged or stopped.

Next, when the engaging portion 118 of the switching lever 114 is placed in the neutral position, the outlet side of the switching passage 109 is extremely minutely formed by the valve hole 129 and the flow passage 145 like the virtual line of FIG. It is slightly through the gap, ie almost closed.

Thus, the hot water from the pump is stopped by the partition wall 104a and the seal packing 110.

This neutral position means that water is not ejected from the shower jet hole 140 and the jet jet hole 155, and the exit of the switching passage 109 at this neutral position is necessarily located at the position of the virtual line of FIG. For example, if it faces the wall surface on the opposite side of the valve hole 129, that is, the partition wall 104b, the discharge of the hot water is completely closed by the packings 108 and 110, and the shower jet hole 140 and the jet are prevented. From the jet hole 155, water is not brought out at all.

Next, the holder 102 in FIGS. 5 to 7 will be described.

The bottom surface of the base 157 made of synthetic resin or the like is a suitable number, and in this embodiment, a pair of suckers 158a and 158b are fixed with the adsorption surface outward.

A sliding surface 161 corresponding to the sliding engagement surface 105 is formed.

That is, the sliding surface 161 is formed with an undercut curved surface 162 that is bent outwardly, and the curved surface 105a of the sliding body portion 104 is fitted to the curved surface 162, so that the nozzle 7 in the main body 101 is prevented from falling out in the E direction, that is, forward.

In addition, the end surface 163 of the insertion groove 160 functions as a locking surface that is the insertion end point of the nozzle body 101.

The bottom of the insertion groove 160 is formed with a guide groove 164 meandering as it enters from the front end side.

The guide groove 164 is a circumferential cross section of the guide groove 164 as the engaging portion 118 of the lever is inserted when the sliding body portion 104 of the nozzle body 101 is inserted into the insertion groove 160. The cam surface 165 rotates the engaging portion 118 of the switching lever 114 to a predetermined rotational position when the nozzle body 101 is inserted and removed.

In this embodiment, as shown in the phantom line of FIG. 6, the nozzle body 101 is inserted into the groove body 160 after the engaging portion 118 is brought into the state where the shower classification is ejected from the switching lever 114 at the position A of the drawing. ) And pushed downward in FIG. 6, the engaging portion 118 enters along the guide groove 164, where the engaging portion 118 is rotated by the pressing force of the cam surface 165a. When the nozzle body 101 is inserted into the insertion groove 160 again, the engaging portion 118 is positioned at the jet ejection operation position at the position C of FIG. 6 at the insertion end point. It is supposed to come.

When the nozzle body 101 is taken out from the insertion groove 160, the engaging portion 118 is rotated to the opposite side by the cam surface 165b, and the extraction is completed when the nozzle body 101 is returned to the jetting operation position of the original shower classification.

That is, the cam surface 165a is formed as a surface which presses the engagement part 118 at the time of insertion of the nozzle main body 101 from the jetting operation position of a shower jet to the jetting operation position of jet jet flow, and also the cam surface 165b. The engaging portion 118 is formed as a surface for moving the engaging portion 118 from the jetting operation position of the jet jet flow to the jetting operation position of the shower jet when the nozzle body 101 is pulled out.

In this way, the holder 102 is suction-fixed by inserting the insertion hole of the insertion groove 160 upward on the inner wall surface of the bathtub using the suction plates 158a and 158b.

The height at which the holder 102 is fixed in the bathtub is a height at which the nozzle body 101 does not come out of the hot water filled in the bathtub 166.

When the sliding body 104 of the nozzle body 101 is inserted into the insertion groove 160 with respect to the holder 102 fixed in this way, the nozzle body 101 is held on the inner wall surface of the bathtub.

When the nozzle body 101 is completely held by the holder 102, the engaging portion 118 of the lever 114 is automatically adjusted to the position of jet jet flow by the cam surface 165a, so that the jet jet hole ( Jet classification is ejected from 155, and a bath massage is performed.

Next, when the nozzle body 101 is pulled out upward from the holder 102, the engaging portion 118 is fitted to the position of the shower classification by the cam surface 165b, and thus the position of the jet classification from the nozzle body. Since the jet is not ejected from the nozzle body and directed toward the eyes or ears, there is no danger. In this way, when the nozzle body 101 is pulled out from the holder 102, an intermittent shower classification is ejected from the shower jet hole group 14a-141c.

Receiving this intermittent shower classification on the body gives an intermittent stimulus different from jet classification.

In the above embodiment, when the nozzle body 101 is inserted into the holder 102, the rotational position of the engagement lever 118 of the switching lever becomes the jetting operation position of the jet jet flow, and then the nozzle body 101 is completely The cam surface 165 is formed so as to be in the shower classification jetting operation position when taken out, and the shape of the cam surface 165 can be changed in various ways according to the specification.

For example, at the position where insertion of the nozzle body 101 is completed, the engaging portion 118 becomes the jetting operation position of the jet jet flow, and the cam surface becomes a neutral position at the position where the nozzle body 101 has been removed. 165) may be formed.

In addition, this invention is not limited to the said Example, A various embodiment can be taken.

For example, in the above embodiment, the guide groove 164 is installed on the bottom surface of the insertion groove 160, but according to the attachment form of the switching lever 114 on the nozzle body 101 side, the sidewall of the insertion groove 160, etc. It can also be formed on the wall.

In addition, in the above embodiment, the jet jet and the intermittent shower jet are selectively ejected from the jet surface of the nozzle body 101. However, the jet jet and the intermittent shower jet can be ejected, for example. It may be.

In this case, when the nozzle body 101 is configured to eject only jet jet, the cam surface 165 moves the engaging portion 118 of the switching lever 114 to the jet ejection flow position at the insertion completion position of the nozzle main body 101. The position of the nozzle body 101 may be adjusted to the neutral position (the position of the engaging portion 118 where the jet classification is not ejected).

In addition, when the nozzle body 101 is configured to eject only the intermittent shower classification, the engagement of the switching lever 114 with the holder 102 at the insertion position of the nozzle body 101 is neutral, for example. The cam body 165 is formed at the position (the position at which the shower classification does not eject) and the engagement 118 is aligned at the ejection position of the shower jet flow at the position where the nozzle body 101 has been removed. After taking out 101, the user can perform massage by the intermittent shower classification without having to operate the switching lever 114.

In addition, when the holder 102 is fixed to the inner wall of the bath located above the water surface of the bathtub, the switching lever 114 is hooked at the position where the nozzle body 101 is inserted into the holder 102. Aligning the fitting portion 118 with the shower jet operation position, and forming the cam surface 165 to align the fitting portion 118 to the neutral position at the extraction completion position of the nozzle body 101, the nozzle body in the holder 102 The intermittent shower classification is automatically ejected from the shower jet hole 140 while the 101 is inserted and held therein, so that the intermittent shower of the nape can be taken without using a hand by fitting it to the nape of the neck.

As such, the type of jetting jetted from the nozzle body 101 can be arbitrarily selected, and a cam face 165 suitable for use is set according to the type of jetting jet.

In the above embodiment, the shower classification is constituted by an intermittent shower, but this may be a continuous shower.

In this case, the vanes 142 in the vans accommodating chamber 135 may be omitted.

In the present invention, the sucker is installed on the holder holding the nozzle body so that the holder is detachably formed on the inner wall of the bathtub, so that the fixing position of the holder is changed, so that it is possible to massage the desired part of the body.

In addition, since the cam face is formed on the insertion wall surface inserted by the nozzle body, and the cam switching action of the cam body is configured to switch, the nozzle body is inserted into the holder. Only when the lever is set to the jet classification position and the cam face is formed so that it is in the neutral position or the shower jet ejection operation position when the nozzle body is removed from the holder, the jet classification even if the nozzle body classifying jet classification is removed from the holder. Is automatically safe because it automatically stops or switches to the shower category.
