Abstract

PROBLEM TO BE SOLVED: To provide a mist generator and shower head to be used for the same capable of improving a beauty effect.SOLUTION: A liquid flowing in a liquid flow channel 11 is allowed to collide with a gas flowing in a gas flow channel 12 in a confluence part 13 so as to generate mist, and then the generated mist is supplied to an outside through a mist supply passage 14. A pulse is generated in the mist by resistance to be received by the mist in the mist supply passage 14, to thereby oscillate the mist supply passage 14 with the pulse. Since the mist can be supplied to the outside in a state where atomization is sufficiently performed in the mist supply passage 14, a beauty effect is improved. Besides, since the mist supply passage 14 can be oscillated, the beauty effect is improved by using the oscillation.

Description

  The present invention relates to a mist generating device that generates mist using a liquid and a shower head used therefor.

  For example, in a beauty salon or the like, there is a case where a mist generating device for injecting mist onto the hair of a person to be treated is used (for example, see Patent Document 1 below). A general mist generating apparatus includes a tank capable of storing water, and can generate mist by heating water in the tank.

  On the other hand, in the shower head used for hair washing, etc., the hot water supplied from the water heater is atomized at the nozzle provided in the shower head, and mist can be injected together with the hot water. (See, for example, Patent Document 2 below). Such a shower head is attached to, for example, a hose extending from a faucet, and is configured such that hot water supplied from a water heater via a faucet is atomized at the same time as jetting.

JP 2010-172525 A JP 2001-198037 A

  In the conventional mist generator as exemplified in Patent Document 1, the generated mist can be sprayed on the hair of the person to be treated, but other cosmetic effects cannot be exhibited. Therefore, although a certain amount of installation space is required, it cannot be said that a cosmetic effect sufficient to meet that requirement is obtained, and a mist generating device with a higher cosmetic effect has been desired.

  Moreover, since the shower head as illustrated in Patent Document 2 can spray mist together with hot water just by attaching to a hose extending from the faucet, it exhibits a beauty effect without requiring installation space. be able to. However, since this type of shower head is configured to atomize hot water at the same time as jetting, it is difficult to sufficiently atomize and it is difficult to say that a high cosmetic effect can be obtained.

  This invention is made | formed in view of the said situation, and it aims at providing the mist generator which can improve a beauty effect, and the shower head used for this.

  A mist generating apparatus according to the present invention is a mist generating apparatus that generates mist using a liquid, a liquid channel through which a liquid flows, a gas channel through which a gas for generating mist flows, and the liquid channel And the gas flow path, a merging portion that generates mist by colliding the liquid flowing through the liquid flow path and the gas flowing through the gas flow path, and supplying the mist generated at the merging portion to the outside And a mist supply path for causing the mist to pulsate by the resistance received by the mist in the mist supply path, and causing the mist supply path to vibrate accordingly.

  According to such a configuration, mist generated by the collision of the liquid flowing through the liquid flow path and the gas flowing through the gas flow path at the junction is supplied to the outside via the mist supply path. Thereby, since the mist can be supplied to the outside in a sufficiently atomized state in the mist supply path, the cosmetic effect can be improved as compared with the conventional configuration in which mist is generated in the shower head. it can.

  In particular, the mist can be pulsated by the resistance that the mist receives in the mist supply path. Since the mist supply path can be vibrated as the mist pulsates, the cosmetic effect can be improved by utilizing this vibration.

  For example, if a head (shower head or mist head) connected to the mist supply path is brought into contact with the scalp of the person to be treated, vibration from the mist supply path is ejected through the head while ejecting mist from the head. Can be transmitted to the scalp to obtain a massage effect. Thus, in addition to the beauty effect by the mist, the beauty effect by the massage effect is also obtained, so that it is possible to provide a mist generating device having a very high beauty effect.

  The liquid flow path may be provided with a liquid pump for sending liquid to the merging part side, and the gas flow path may be provided with a gas pump for sending gas to the merging part side. In this case, the pressure of the gas pump may be set higher than the pressure of the liquid pump.

  According to such a configuration, the liquid is sent to the merging portion side by the liquid pump, the gas is sent to the merging portion side by the gas pump, and the liquid and the gas collide at the merging portion, thereby improving the mist. Can be generated. In particular, since the pressure of the gas pump is set higher than the pressure of the liquid pump, finer mist can be generated and pulsation is likely to occur in the mist due to the pressure difference of the pump. Therefore, the beauty effect can be further improved.

  The liquid channel may be supplied with warm water as a liquid from a water heater.

  According to such a structure, mist can be generated using the hot water supplied from a water heater. Accordingly, it is possible to generate a mist that is warm and has a high beauty effect without providing a heater or the like.

  The mist generation device may further include a liquid supply path that branches from the liquid flow path and supplies the liquid to the outside.

  According to such a configuration, not only can mist be supplied to the outside via the mist supply path, but also liquid can be supplied to the outside via the liquid supply path branched from the liquid flow path. Therefore, the cosmetic effect can be further improved by using both mist and liquid.

  In particular, in the case of a configuration in which hot water is supplied from the water heater to the liquid flow path, if the hot water is supplied to the liquid flow path only to generate mist, the flow rate from the water heater is too small, There is a risk that the water does not warm in the water heater. However, as in the present invention, the flow rate from the water heater increases because the hot water supplied to the liquid flow path is guided not only to the merging portion side but also to the liquid supply path side. Can supply hot water well.

  The mist generator may further include a shower head to which the mist supply path and the liquid supply path are connected. In this case, the shower head is formed with a mist injection port for injecting the mist supplied from the mist supply path and a liquid injection port for injecting the liquid supplied from the liquid supply path. May be.

  According to such a configuration, since both mist and liquid can be ejected from the shower head, the cosmetic effect can be further improved. If no gas flows from the gas flow path to the junction, the liquid flowing in the liquid flow path passes through the mist supply path as it is and is ejected as liquid from the mist ejection port of the shower head. In this case, the liquid is ejected from both the liquid ejection port and the mist ejection port of the shower head, and can be used as a normal shower.

  That is, according to the present invention, it is possible not only to use the shower head in a usage manner having a high cosmetic effect by the mist ejected from the mist ejection port and the liquid ejected from the liquid ejection port, In addition, the liquid can be ejected from both the liquid ejection port and the shower head can be used in a normal shower mode. In this way, it is possible to provide an easy-to-use mist generating device that plays two roles.

  A plurality of the liquid ejection ports may be formed so as to surround the mist ejection port.

  According to such a configuration, the mist ejected from the mist ejection port is covered with the curtain formed by the liquid ejected from the liquid ejection port. Thereby, while being able to improve the beauty effect by mist, the silencing effect with respect to the sound produced in a mist injection port can be exhibited.

  A shower head according to the present invention is a shower head used in a state of being connected to a mist generating device, wherein a mist supply port to which a mist supply path for supplying mist from the mist generating device is connected, and a liquid A liquid supply port to which a liquid supply path for supply is connected, a mist injection port for injecting mist supplied from the mist supply path via the mist supply port, and the liquid supply from the liquid supply path And a liquid injection port for injecting the liquid supplied through the port, and a plurality of the liquid injection ports are formed so as to surround the mist injection port.

  According to such a configuration, since the mist can be supplied from the mist supply path in a sufficiently atomized state through the mist supply port and can be injected from the mist injection port, mist is generated in the shower head. Compared to the conventional configuration, the beauty effect can be improved.

  Further, the mist ejected from the mist ejection port is covered with the curtain formed by the liquid ejected from the liquid ejection port. Thereby, while being able to improve the beauty effect by mist, the silencing effect with respect to the sound produced in a mist injection port can be exhibited.

  According to the present invention, since the mist can be supplied to the outside in a sufficiently atomized state in the mist supply path, the cosmetic effect can be improved. Further, according to the present invention, since the mist supply path can be vibrated, the cosmetic effect can be improved by utilizing this vibration.

It is the schematic which showed the example of a structure of the mist generator which concerns on one Embodiment of this invention. It is the front view which showed the structural example of the shower head. It is AA sectional drawing of the shower head of FIG.

  FIG. 1 is a schematic diagram showing a configuration example of a mist generating apparatus 1 according to an embodiment of the present invention. The mist generating device 1 is attached to, for example, a hose 3 extending from the faucet 2 and can generate mist using hot water supplied from the water heater (not shown) through the faucet 2.

  The mist generating device 1 includes a liquid flow path 11, a gas flow path 12, a merging portion 13, a mist supply path 14, a liquid supply path 15, a liquid pump 16, a gas pump 17, a control board 18, a foot switch 19, and the like. ing. Among these units, for example, the liquid channel 11, the gas channel 12, the merging unit 13, the liquid pump 16, the gas pump 17, and the control substrate 18 are accommodated in the housing 10.

  The liquid flow path 11 and the gas flow path 12 are connected at the junction 13 and communicate with the mist supply path 14 respectively. Specifically, each end portion of the liquid flow path 11, the gas flow path 12, and the mist supply path 14 is connected to the merge portion 13 constituted by a three-way joint. The mist supply path 14 is connected at one end to the junction 13 in the housing 10 and extends to the outside of the housing 10 at the other end.

  The liquid channel 11 is connected to, for example, a connection port 10 a provided in the housing 10. A hose 3 extending from the faucet 2 or the like can be attached to and detached from the connection port 10a. Thereby, hot water can be supplied to the liquid flow path 11 from the water heater through the faucet 2, the hose 3, and the connection port 10a. When attaching the mist generating device 1 to the hose 3, it is only necessary to remove the shower head originally attached to the end of the hose 3 and attach the end of the hose 3 to the connection port 10a of the mist generating device 1. .

  The liquid pump 16 is constituted by a reciprocating pump such as a piston pump, for example, and is provided in the liquid flow path 11 through which hot water flows. By driving the liquid pump 16, the hot water in the liquid flow path 11 can be sent to the merging portion 13 side at a predetermined pressure. A check valve 11 a is provided downstream of the liquid pump 16 in the liquid flow path 11, so that the warm water sent to the merging portion 13 side by the liquid pump 16 does not flow backward.

  The gas pump 17 is constituted by a reciprocating pump such as a piston pump. By driving the gas pump 17, air as a gas for generating mist is sent out to the merging portion 13 side through the gas flow path 12 at a predetermined pressure. A check valve 12 a is provided downstream of the gas pump 17 in the gas flow path 12, so that the air sent to the merging portion 13 side by the gas pump 17 does not flow backward.

  The hot water flowing through the liquid flow channel 11 and the air flowing through the gas flow channel 12 collide with each other at the junction 13, and mist is generated by this collision. In this example, the discharge pressure of the liquid pump 16 is about 0.2 to 0.3 MPa at the maximum, and hot water is supplied from the liquid channel 11 to the junction 13 at a flow rate of about 2 to 3 L / min. ing. Further, the discharge pressure of the gas pump 17 is about 0.5 MPa at the maximum, and air is supplied from the gas flow path 12 to the joining portion 13 at a flow rate of about 80 L / min.

  Thus, in this embodiment, the pressure of the gas pump 17 is set higher than the pressure of the liquid pump 16. As a result, the hot water and air collide with each other at high pressure in the junction 13, and high-pressure mist generated by the collision is supplied to the outside through the mist supply path 14.

  The liquid supply path 15 branches from the liquid flow path 11. Specifically, one end side of the liquid supply path 15 is connected to the liquid channel 11 between the connection port 10 a and the liquid pump 16, and the other end side extends to the outside of the housing 10. Thereby, the hot water supplied from the water heater to the liquid flow path 11 through the faucet 2, the hose 3 and the connection port 10a is guided not only to the junction 13 side but also to the liquid supply path 15 side. It is supplied to the outside through a path 15.

  Each end of the mist supply path 14 and the liquid supply path 15 opposite to the mist generator 1 side is connected to the shower head 100. Thereby, both the mist supplied from the mist supply path 14 and the hot water supplied from the liquid supply path 15 can be ejected from the shower head 100. The flow rate of mist ejected from the shower head 100 is, for example, about 1 L / min, and the flow rate of hot water ejected from the shower head 100 is, for example, about 10 L / min.

  The control board 18 constitutes a control unit for controlling the operation of each unit provided in the mist generating device 1, and controls the driving of the liquid pump 16 and the gas pump 17, for example. A foot switch 19 is connected to the control board 18 so that the practitioner can operate with the foot. By operating the foot switch 19, the liquid pump 16 and the gas pump 17 are driven to generate mist, and the mist can be supplied from the mist supply path 14.

  As a specific procedure for generating mist, first, hot water is supplied to the mist generator 1 through the hose 3 by opening the faucet 2. At this time, the liquid pump 16 and the gas pump 17 are in a stopped state, and at first, only the water before warming is jetted from the shower head 100. Thereafter, by operating the foot switch 19 after confirming that hot water has started to be injected, mist can be generated in the mist generating device 1 and mist can be injected from the shower head 100 together with the hot water. Mist is injected at the same temperature as the temperature of hot water set in the water heater.

  In the present embodiment, the resistance that the mist receives in the mist supply path 14 causes pulsation in the mist, and the mist supply path 14 can be vibrated accordingly. That is, by configuring the mist supply path 14 with an elongated tubular member, the resistance received by the mist in the mist supply path 14 can be increased, and pulsation can be generated satisfactorily.

  The pulsation as described above can be generated more favorably by configuring one or both of the liquid pump 16 and the gas pump 17 with a reciprocating pump such as a piston pump. At this time, the mist supply path 14 can be set to an inner diameter and a length that easily cause pulsation in consideration of the relationship with the pressure of the liquid pump 16 or the gas pump 17. Can be set to about 1 to 1.5 m.

  As described above, in the present embodiment, the mist generated by the collision of the hot water flowing through the liquid flow channel 11 and the air flowing through the gas flow channel 12 at the junction 13 is externally (via this mist supply channel 14). In the example, it is supplied to the shower head 100). Thereby, since the mist can be supplied to the outside in a sufficiently atomized state in the mist supply path 14, the cosmetic effect is improved as compared with the conventional configuration in which mist is generated in the shower head. Can do.

  Moreover, since the mist can be generated using the hot water supplied from the water heater, it is possible to generate a mist that is warm and has a high beauty effect without providing a heater or the like.

  In particular, in this embodiment, the mist can be caused to pulsate due to the resistance received by the mist in the mist supply path 14. Since the mist supply path 14 can be vibrated as the mist pulsates, the cosmetic effect can be improved by utilizing this vibration.

  For example, if the shower head 100 connected to the mist supply path 14 is brought into contact with the scalp of the person to be treated, vibration from the mist supply path 14 via the shower head 100 is performed while ejecting mist from the shower head 100. Can be transmitted to the scalp to obtain a massage effect. Thus, in addition to the beauty effect by mist, the beauty effect by the massage effect is also obtained, so that the mist generator 1 having a very high beauty effect can be provided.

  Moreover, in this embodiment, while sending warm water to the confluence | merging part 13 side with the liquid pump 16, sending air to the confluence | merging part 13 side with the gas pump 17, and making these warm water and air collide with the confluence | merging part 13, Mist can be generated satisfactorily. In particular, since the pressure of the gas pump 17 is set higher than the pressure of the liquid pump 16, finer mist can be generated and pulsation is likely to occur in the mist due to the pressure difference between the pumps 16 and 17. Therefore, the beauty effect can be further improved.

  Furthermore, in this embodiment, not only can mist be supplied to the outside via the mist supply path 14, but also hot water can be supplied to the outside via the liquid supply path 15 branched from the liquid flow path 11. Therefore, the cosmetic effect can be further improved by using both mist and hot water.

  In particular, in the case where the hot water is supplied from the water heater to the liquid channel 11 as in the present embodiment, if hot water is supplied to the liquid channel 11 only to generate mist, Since the flow rate from the water heater is too small, the water may not warm in the water heater. However, since the hot water supplied to the liquid flow path 11 is guided not only to the merging portion 13 side but also to the liquid supply path 15 side as described above, the flow rate from the water heater increases. The hot water can be supplied satisfactorily from the water heater.

  FIG. 2 is a front view showing a configuration example of the shower head 100. 3 is a cross-sectional view taken along the line AA of the shower head 100 in FIG. This shower head 100 is provided with a gripping part 101 for a practitioner to hold, and an injection part 102 for injecting mist and hot water toward the patient.

  The grip portion 101 is formed in a hollow shape, for example, and a mist joint 111 and a liquid joint 112 are provided therein. An inlet 113 for introducing the mist supply path 14 and the liquid supply path 15 into the inside is formed at the end of the grip 101.

  The mist joint 111 is connected to the end of the mist supply path 14 introduced from the introduction port 113 so that the mist is supplied from the mist generator 1 side. At this time, a connection port with the end of the mist supply path 14 in the mist joint 111 constitutes a mist supply port 114 through which mist is supplied from the mist supply path 14.

  On the other hand, the end of the liquid supply path 15 introduced from the introduction port 113 is connected to the liquid joint 112 so that hot water is supplied from the mist generating device 1 side. At this time, the connection port with the end of the liquid supply path 15 in the liquid joint 112 constitutes a liquid supply port 115 to which hot water is supplied from the liquid supply path 15.

  The injection unit 102 is formed in a cylindrical shape, for example, and one end thereof is connected to the grip unit 101 with a partition plate 121 interposed therebetween. In order to inject hot water supplied from the liquid supply path 15 and the mist injection plate 123 in which a plurality of mist injection ports 122 for injecting mist supplied from the mist supply path 14 are formed inside the injection unit 102. And a liquid ejection plate 125 in which a plurality of liquid ejection ports 124 are formed.

  The mist injection plate 123 has a circular shape, for example, and is located at the center of the injection unit 102. On the other hand, the liquid ejection plate 125 has, for example, an annular shape, and is positioned so as to surround the mist ejection plate 123. Thus, a plurality of liquid ejection ports 124 are formed so as to surround the mist ejection port 122. In this example, the mist ejection plate 123 and the liquid ejection plate 125 are arranged at different heights so as not to be located in the same plane, whereby the mist ejection port 122 is more external than the liquid ejection port 124. It is located on the side (opposite the gripping part 101 side).

  A mist introduction space 126 for guiding the mist supplied from the mist supply path 14 via the mist supply port 114 to the mist injection port 122 is formed between the mist injection plate 123 and the partition plate 121. The mist joint 111 is formed, for example, in an L shape, and is attached to the partition plate 121 so as to communicate the mist supply path 14 and the mist introduction space 126.

  An annular liquid introduction space 127 is formed between the liquid ejection plate 125 and the partition plate 121 to guide the hot water supplied from the liquid supply path 15 through the liquid supply port 115 to the liquid ejection port 124. Yes. The liquid joint 112 is formed, for example, in an L shape, and is attached to the partition plate 121 so as to communicate the liquid supply path 15 and the liquid introduction space 127.

  The mist ejecting plate 123 and the liquid ejecting plate 125 are disposed on the inner side (the gripping portion 101 side) than the end face 128 on the side opposite to the gripping portion 101 side in the ejecting portion 102. Therefore, when the shower head 100 is used in a state where the end surface 128 of the ejection unit 102 is in contact with the scalp of the patient, the space between the end surface 128, the mist ejection plate 123, and the liquid ejection plate 125, Mist and hot water can be injected.

  However, the mist ejection plate 123 and the liquid ejection plate 125 may be configured to be provided at substantially the same position as the end surface 128 of the ejection unit 102. Further, the mist ejection plate 123 and the liquid ejection plate 125 are not limited to the configuration arranged at different heights, and may be located in the same plane. Furthermore, the mist ejection plate 123 and the liquid ejection plate 125 are not limited to the configuration formed by separate members, and may be integrally formed by the same member.

  In this embodiment, since both mist and warm water can be ejected from the shower head 100, the cosmetic effect can be further improved. If air does not flow from the gas flow path 12 to the junction 13, the hot water flowing through the liquid flow path 11 passes through the mist supply path 14 as it is and is ejected as liquid from the mist injection port 122 of the shower head 100. In this case, the liquid (hot water) is ejected from both the liquid ejection port 124 and the mist ejection port 122 of the shower head 100, and can be used as a normal shower.

  That is, in this embodiment, not only can the shower head 100 be used in a usage mode with a high cosmetic effect by the mist ejected from the mist ejection port 122 and the hot water ejected from the liquid ejection port 124, but also the mist It is also possible to use the shower head 100 in a normal shower mode by injecting hot water from both the ejection port 122 and the liquid ejection port 124. In this way, it is possible to provide the mist generator 1 that is easy to use with two roles.

  In the present embodiment, the mist ejected from the mist ejection port 122 is covered with a cylindrical curtain formed by hot water ejected from the liquid ejection port 124. Thereby, the beauty effect by mist can be enhanced, and the mute effect for the sound generated at the mist injection port 122 can be exhibited.

  In the above embodiment, a configuration has been described in which the practitioner operates the foot switch 19 with his / her foot to drive the liquid pump 16 and the gas pump 17. However, the configuration is not limited to such a configuration, and the configuration may be such that the practitioner drives the liquid pump 16 and the gas pump 17 by performing an operation at a site other than a foot such as a hand.

  Alternatively, the liquid pump 16 and the gas pump 17 may be driven in a predetermined manner by executing a program by a control unit configured by the control board 18. Furthermore, the mist generating device 1 according to the present embodiment can be operated not only by the practitioner but also by the practitioner himself.

  The liquid flowing through the liquid flow path 11 is not limited to hot water, and may be water at room temperature or a liquid other than water. Further, the gas flowing through the gas flow path 12 is not limited to air but may be other gases. In this case, it is preferable that at least one of the liquid flowing through the liquid channel 11 and the gas flowing through the gas channel 12 includes a component having a high cosmetic effect.

  In the above embodiment, the shower head 100 that can eject the mist supplied from the mist supply path 14 and the liquid supplied from the liquid supply path 15 has been described, but the mist head that ejects only the mist is also described. The present invention can be applied. Further, when the present invention is applied to the shower head 100, it is possible to provide not only the mist generating device 1 provided with the shower head 100 but also the shower head 100 alone.
