Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vapor spray device used for cosmetic purposes such as facial beauty and hair styling, and more particularly to a handpiece that facilitates the use of the device.

[0002]

[Prior art]

 As a steam spraying device used for cosmetic purposes, the one described in Japanese Utility Model Publication No. 3-45729 shown in FIG. 4 is known. In the figure, 1 indicates the entire vapor spraying device. Reference numeral 2 denotes a steam generating part which is a part of the steam spraying device 1, and has a steam generating tank 3, an opening / closing lid 4, and a heater 5.

Reference numeral 6 is a vapor discharge cylinder, and a discharge nozzle 7 for spraying vapor is attached to the upper and left sides of the figure. The steam generation tank 3 and the steam discharge tube 6 are connected to each other by a steam pipe 8 and a drip return pipe 9, and an intermediate tank 10 is arranged between these pipes and pipes.

One end of the steam pipe 8 communicates with the upper space portion 3 a of the steam generation tank 3 through this intermediate tank 10, and the other end projects from the bottom of the steam discharge cylinder 6 into the same, and from the bottom. It opens at a separated position. Attached to the open end 8a is a droplet drop pipe 12 consisting of a cap having two slits 11 (only one is shown in the figure) on the side, and droplets are ejected from the vapor discharge nozzle 7. To prevent this. The molten metal return pipe 9 opens at the bottom of the steam discharge cylinder 6 and communicates with the lower part of the steam generation tank 3 via the intermediate tank 10, so that the molten metal droplets generated in the steam discharge cylinder 6 are transferred to the intermediate tank 10 and the intermediate tank 10. The steam is generated in the steam generation tank 3.

A liquid level sensor 13 is attached to the inside of the vapor discharge cylinder 6, and when a drop of water accumulates to a height of b in the figure, an alarm 15 is activated via a signal line 14 to stop the operation of the device. It has become.

When water having a predetermined water level or lower as shown in a in the figure is put in the steam generation tank 3 and heated by the heater 5, the water boils and the upper space 3 a is filled with steam. The filled steam enters the steam discharge tube 6 through the steam pipe 8. The steam condensed in the steam pipe 8 becomes hot water droplets and flows backward in the steam pipe 8 and falls into the intermediate tank 10 or is extruded from the slit 11 of the hot water droplet separating pipe 12 into the steam discharge cylinder 6 to generate steam. It is returned to the intermediate tank 10 and the steam generation tank 3 through the hot water drop return pipe 9 together with the hot water droplets condensed in the discharge cylinder 6. With the above-mentioned configuration, the stable and stable steam is sprayed from the steam discharge nozzle 7, and is used for beauty treatment such as facial treatment and hair styling.

[0007]

[Problems to be solved by the device]

 However, in the conventional device as described above, a rigid pipe is used for the steam pipe 8 and the drip return pipe 9, and the steam generation tank 3 and the steam discharge cylinder 6 configured together with the water tank are integrated. Therefore, when spraying the generated steam on the face or hair, the user needs to bring a beauty target such as the face or hair near the steam discharge nozzle 7, which is inconvenient to use and is not always necessary. It was not easy to use.

On the other hand, if the steam pipe 8 and the drip return pipe 9 are replaced with flexible and long pipes, only the vapor discharge cylinder 6 can be moved to spray the vapor to a desired portion. With such a configuration, since hot steam passes through the steam pipe 8, the insulation is not sufficient with a normal flexible tube, and when the steam discharge tube 6 is brought close to the face, the tube is inadvertently touched. There is a risk of burns. In addition, the hot water drop return pipe 9 for returning the hot water drops generated in the nozzle case is naturally long, which makes it difficult to return the hot water drops to the steam generation tank without difficulty.

[0009]

[Problems to be solved by the device]

 The present invention provides a handpiece that can bring only the steam discharge nozzle part to the hand or face independently of the steam generator, eliminates the inconvenience, and has a convenient steam spraying function. It is the one that tries to make the best use.

Another object of the present invention is to provide a handpiece that can be used as desired by tilting the vapor discharge nozzle portion in any direction. Another object of the present invention is to provide a handpiece which has a simple connection structure between the steam generator and the handpiece and is easy to operate without being burned during operation.

[0011]

[Means for Solving the Problems]

 In order to achieve each of the above objects, the handpiece of the present invention comprises a flexible vapor feed tube whose one end is connected to a vapor generator, a nozzle case with a spray nozzle, and a tip with a water drop separation tube. Side is located in the nozzle case, the base end side is opened to the outside of the nozzle case, the opening is connected to the other end of the steam feed tube, and one end is connected to the bottom of the nozzle case. The other end is configured with a flexible drain return tube connected to the steam generator, and the water droplets generated in the nozzle case are circulated to the steam generator through the drain return tube.

In this case, since the flexible steam feed tube described above has a high temperature due to the steam passing through the inside thereof, a large number of tubes are provided on the outer circumference thereof so as not to be touched or burned. Nozzle case and steam generation are performed in order to allow the heat dissipation effect of the projection to be exhibited and to efficiently return the water droplets generated in the nozzle case to the steam generator. A drain pump may be interposed in the drain return tube that is connected to the device, and the suction function of the drain pump may positively recirculate the molten metal toward the steam generation tank. Furthermore, regarding the nozzle case, when holding and using it, no matter what position or posture it occupies, in order to prevent the water droplets generated in the nozzle case from being ejected from the spray nozzle, The nozzle case has an elongated shape, openings are formed at both ends of the nozzle case, a communication pipe with a branch is provided between both openings, and valve seats are provided on both sides of the branch in the communication pipe. A ball valve that separates from and contacts the valve seat is constructed to have a switching valve.In addition, the parallel flow path parts of the drain return tube and the steam feed tube are integrated in parallel, and the steam generator is connected to the nozzle case. The space may be connected by a single flexible cord, and the structure may be easy to operate.

[0013]

[Action]

 The steam sent from the steam discharge nozzle of the steam generator is sent to the steam supply pipe by a flexible steam sending tube. At that time, the water droplets generated in the nozzle case are separated by the water droplet separator at the tip of the steam supply pipe and accumulated in the nozzle case, and only the steam is ejected from the spray nozzle. The water droplets accumulated in the nozzle case are also sucked by the drain pump and returned to the steam generator through the drain return tube through the opening at the bottom of the nozzle case. The drain pump is fixed near the steam generator, and the handpiece, including the nozzle case, can be placed as close to the face or hair as the flexible steam delivery tube and drain return tube allow. Can be moved to. Also, since both tubes have a large number of ribs formed on the outer circumference, there is sufficient heat dissipation, and there is no risk of burns if the user touches them carelessly during handling.

Further, by forming openings at both ends of the nozzle case and connecting them with a communicating pipe, and providing a switching valve in the middle of the communicating pipe, no matter how the handpiece is tilted Is collected on the lower opening side in the longitudinal direction of the nozzle case and can be sucked by the drain return tube, so there is no inconvenience in discharging the generated water droplets.

Furthermore, by integrating the parallel flow path portions of the drain return tube and the vapor feed tube into a flexible cord-like body, these tubes are integrated into one and the configuration as a handpiece is simplified. It becomes easier to use.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a state in which a handpiece of a cosmetic steam spraying device according to the present invention is attached to a steam generator. As the steam generator A, the same one as the steam spraying device 1 described in FIG. 4 as a conventional example can be used. Although not shown in FIG. 1, a liquid level sensor 13 is installed in the vapor discharge cylinder 6, and when the water droplets are accumulated up to the height of b in the figure, an alarm device 15 is activated via a signal line 14 to activate the device. The structure for stopping the operation of is similar to that of the conventional device of this type. Further, in the embodiment of the present invention, a detector 16 for monitoring the upper limit of the water level and a detector 17 for monitoring the lower limit of the water level are provided in the intermediate tank 10 to add a configuration for notifying an abnormal water level. I am doing it.

A male screw is formed on the outer circumference of the vapor discharge nozzle 7, and one end of a vapor feed tube 21 is hermetically connected by a bag nut 20 screwed to the male screw. FIG. 2 shows an example of this connection state. A pipe joint 22 having a flange portion is fitted into the cap nut 20, and one end of the steam feed tube 21 is fitted and fixed to the pipe joint 22. The packing 23 is fitted between the flange portion of the pipe joint 22 and the discharge nozzle 7, and the cap nut 20 is screwed into the steam discharge nozzle 7 to prevent steam leakage.

The other end of the steam feed tube 21 is connected to the open end of the steam supply pipe 24, and the steam supply pipe 24 projects from the bottom surface of the elongated nozzle case 25 to the inside thereof. And a water drop separator 26 is provided at the tip position separated from the bottom surface. The hot water drop separator 26 has the same configuration as the hot water drop separation tube 12 described above.

The nozzle case 25 is provided with a spray nozzle 27 on one side in the approximate center, and openings 25 a and 25 b are provided at both ends of the nozzle case 25, and a communication pipe 28 connects these openings. I am doing it.

A branch portion 28a is provided at the center of the communication pipe 28, and a drain is returned to the branch portion 28a to air-tightly connect one end of the tube 29. The drain return tube 29 is connected to the steam generating device A at a part of the hot water drop returning pipe 9 with a drain pump 30 interposed between the drain returning tube 29 and the steam generating device A. The drain pump 30 is usually fixedly arranged near the steam generator A.

Inside the branch portion 28a, a step is formed on the inner diameter, valve seats 28b and 28c are formed on both sides of the step, and a ball valve body that separates from and contacts the valve seats 28b and 28c is formed in the conduit of the communication pipe 28. 31, 31 are accommodated. Reference numeral 32 is a stopper for the ball valve body 31, and both the ball valve bodies 31, 31 ride on the valve seats 28b, 28c by their own weight to close the pipe line, and the ball valve bodies 31 and 31 drop downward to separate from the valve seat and become stoppers 32. It is movable between the position where it is supported and the line is opened, but which position is occupied depends on the posture in which the nozzle case 25 is gripped. That is, when the nozzle case 25 is in the posture shown in FIG. 1, the upper ball valve body 31 abuts the upper valve seat 28b to close the upper pipe line, and the lower ball valve body 31 lowers the lower valve seat. The lower conduit is released away from 28c. When the nozzle case 25 is turned upside down, the conduit on the valve seat 28c side is closed and the conduit on the valve seat 28b side is opened. That is, the valve seats 28b and 28c and the ball valve elements 31 and 31 constitute the switching valve 33.

FIG. 3 is a perspective view showing a part of the integrated vapor feed tube 21 and the drain return tube 29 in a longitudinal section and enlarged. These tubes are made of a material that is resistant to heat and is also flexible, for example, silicone rubber, and forms two flow passages that are parallel to each other by the two thick and flexible tubes 21 and 29. The outer circumference of each of these is surrounded by a large number of protruding bodies 21a and 29a. The protruding bodies 21a and 29a may have any cross-sectional shape as long as the hands or the like do not directly touch the tube main body portion. In this embodiment, the cross-section has a substantially isosceles triangular shape, Although it is formed as a rib parallel to the axis of the, the outer periphery may be surrounded by a large number of "wart" -shaped projections instead of the ribs. According to this structure, even if steam or hot water passes through the hollow portions 21b and 29b, the tube body is touched via the protruding bodies 21a and 29a, so that the surface temperature is slightly higher than room temperature. It does not get burned, and it is hot and does not touch.

The steam feed tube 21 and the drain return tube 29 are separately arranged by separating them with a knife or the like at a portion where both paths are to be separated without being parallel, but the parallel flow channel It is preferable that the parts are integrated so that the pipes can be integrated into one and the operation of gripping the handpiece including the nozzle case 25 becomes easier.

The steam sent from the steam generator A through the steam feed tube 21 rarely condenses into a drop of water in the middle of the steam feed tube 21 at a high temperature. Even if water droplets are generated, they are pushed by the pressure of the steam to be sent, reach the tip of the steam supply pipe 24, are separated by the water droplet separator 26, and fall into the nozzle case 25. Therefore, the user can hold the nozzle case 25 of the handpiece in his hand and apply the steam from the spray nozzle 27 to the face and hair close to the spray case, and the spray nozzle 27 does not eject water droplets and is comfortable. Can be used.

When the water droplets collect in the nozzle case 25, the drain pump 30 is activated to pump out the hot water accumulated in the nozzle case 25. When the nozzle case 25 is in the posture shown in the drawing, the water droplets collect on the side of the opening 25b. In this case, the ball valve body 31 is placed on the upper valve seat 28b to close the valve, and the ball valve body 31 is separated from the lower valve seat 28c to open the valve. The hot water collected on the side of is drained by the drain pump 30 through the lower valve seat 28c, enters the drain return tube 29, and returns to the steam generator A via the drain return tube 29 and the drain pump 30.

Even if the nozzle case 25 is reversed during use, the hot water accumulated in the nozzle case 25 instantly moves to the opening 25a side, and at that time, the ball valve element 31 is placed on the valve seat 28c. The valve is closed by riding, and the ball valve element 31 is separated from the valve seat 28b which is located below to open the valve, so that the hot water accumulated on the side of the opening 25a can be sucked by the drain pump 30 through the valve seat 28b. That is, no matter what position the nozzle case 25 takes, the water droplets collect in the lower opening, the switching valve 33 automatically switches, and the ball valve element separates from the lower valve seat to open the valve. The drain pump 30 can return the water droplets to the steam generator A.

In the above embodiment, the conventional vapor spraying device 1 was used as the steam generator A, but the handpiece of the present invention is not limited to such a configuration or combination. For example, the steam discharge tube 6 and the steam discharge nozzle 7 may be eliminated and the steam sending tube 21 may be directly connected to the steam pipe 8 of FIG. In that case, the intermediate tank 10 may be provided or may not be provided.

The nozzle case 25 may be fixed to a universal stand (not shown), and the stand may be held in the hand to use the handpiece. It should be noted that, in the above-described configuration, the openings 25a and 25b of the nozzle case 25 can be formed in either one of them. In that case, the switching valve 33 is unnecessary, but the posture of the handpiece during use must always be such that the opening is at the bottom. Also, regarding the nozzle case 25, the liquid level sensor 13, the signal line 14 and the alarm device 15 described in the conventional example are provided so that the operation of the device is stopped when the water droplets accumulate to a certain height. Is desirable.

[0029]

[Effect of device]

 As described above, according to the present invention, since only the spray nozzle portion that ejects steam can be moved to a free position independently of the steam generator, it can be used as a handpiece close to the face or other necessary position. It becomes possible to do. Also, as a handpiece, a nozzle case is equipped with a communication pipe, and a switching valve is built into this, so that no matter what direction the handpiece is tilted, no matter what, while preventing the ejection of water droplets, It can be used in the same way without fear.

Further, by integrally forming the flow path part in which the drain return tube and the steam feed tube run in parallel, the connection structure between the steam generator and the handpiece can be simply summarized and the usability is improved. Can be raised.
