At the same time, the liquid is supplied from the spray nozzle in a sprayed state, thereby improving the slipperiness and adhesion of the suction nozzle to the skin and tightening the skin.
JP 2001-161438 A

  However, since the spray nozzle of Patent Document 1 is provided at a position distant from the suction nozzle, the liquid scatters in addition to the skin suction portion, so that the user feels uncomfortable and the liquid is wasted. There was a problem of being (about 20-40% of the amount of spray water).

  The present invention has been made in order to solve the above-mentioned problem, and provides a facial device that prevents liquid from being scattered other than the skin suction part, eliminates discomfort, and eliminates wasteful use of liquid. It is intended.

In order to solve the above problems, the present invention provides a suction nozzle that abuts against the skin and sucks, a suction pump that applies suction to the suction nozzle, a liquid supply nozzle that supplies liquid to the skin, and a liquid supply nozzle. In a facial device having a liquid tank for supplying liquid, a liquid nozzle is fitted on the outside of the suction nozzle, and a double nozzle tube structure is set so that the suction nozzle and the tip of the liquid supply nozzle are substantially aligned. and the nozzle unit, in the suction nozzle, the is suction force imparted by a suction pump to form a vacuum and name Ru suction passage, between the suction nozzle and the liquid supply nozzle, the liquid is supplied from the liquid tank A liquid supply passage is formed, and a communication passage that connects the suction passage and the liquid supply passage is formed near the tip of the suction nozzle, and the liquid is supplied from the liquid tank to the liquid supply passage by the negative pressure of the suction passage. Like There is provided a facial equipment, characterized in that it is configured.

  In order to make it possible to finely adjust the supply amount of the liquid, it is preferable that the communication path is at least one minute slit formed at the tip of the suction nozzle.

  In order to prevent the liquid in the liquid tank from leaking from the tip of the liquid supply passage, it is preferable that the liquid supply passage is a slit-like groove extending in the nozzle direction.

  In order to make cleaning and replenishment easier, the suction nozzle and the liquid supply nozzle of the double nozzle tube structure are a nozzle unit that can be attached to and detached from a main body housing containing a suction pump and the like. The nozzle unit is preferably a nozzle / tank unit provided with the liquid tank.

  In order to secure a sufficient capacity of the liquid tank, the liquid tank is preferably provided so as to surround the outer periphery of the nozzle unit.

In order to be directly washed in the liquid feed path can be easily, for the suction nozzle, it is preferable to form the liquid supply nozzle is detachable together with the liquid tank.

  In order to eliminate residual water in the liquid tank, it is preferable that a suction passage extending from the rear end portion of the liquid supply passage toward the bottom of the liquid tank is provided.

  According to the present invention, when suctioning the skin, when the suction nozzle of the nozzle unit of the double nozzle tube structure and the tip of the liquid supply nozzle are brought into close contact with the skin, the suction of the suction nozzle is given by the suction pump. Since the passage has a negative pressure, sebum and dirt are sucked and removed, and the tip of the suction nozzle is moved to massage the skin. At the same time, since the negative pressure in the suction passage acts on the liquid tank from the communication passage through the liquid supply passage, the liquid in the liquid tank is sucked up from the liquid supply passage to the suction passage through the communication passage.

  At this time, since the communication path is formed in the vicinity of the tip of the suction nozzle, the liquid sucked up to the communication path is in close contact with the skin by the suction inertia force before being sucked into the suction path. It will be supplied to the skin within the tip of the liquid nozzle. As a result, an appropriate amount of liquid can be supplied to the surface of the skin through the communication path, and since the liquid does not scatter outside from the inside of the tip of the liquid supply nozzle (skin suction part), there is no discomfort and waste of the liquid is eliminated. become.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the facial device 1 includes a main body housing 2, and a battery storage chamber 4 is provided in the lower part of the main body housing 2 so that the battery 6 can be replaced by opening and closing the back cover 5. It has become. An electric motor 7 driven by a battery 6 is provided at an intermediate portion in the main body housing 2 and can be driven / stopped by turning on / off a power switch 8.

  A suction pump 10 that applies a suction force to a suction nozzle 15 (described later), a nozzle unit 11 having a double nozzle tube structure, and the like are provided in the upper part of the main body housing 2, and a liquid supply nozzle 16 (described later). ) Is integrally provided with a liquid tank 12 for supplying liquid. The liquid tank 12 can replenish and discharge liquid by opening and closing the cap 13 of the liquid replenishing port 12a with the hinge portion 13a.

  When the electric motor 7 is driven, the eccentric output shaft 7a rotates eccentrically, and the diaphragm 10a of the suction pump 10 is driven to reciprocate, so that the suction pump 10 reciprocates the nozzle unit 11 by the reciprocating operation of the supply / discharge valve 10b. While performing the suction operation of sucking air from the suction port 11a, the operation of discharging the air from the exhaust port 11b into the main body housing 2 is performed.

  The nozzle unit 11 is composed of a cylindrical suction nozzle 15 that sucks in contact with the skin and a cylindrical liquid supply nozzle 16 that supplies liquid to the skin. The nozzle unit 11 has a front end portion projecting laterally outward from an upper portion of the main body housing 2 and a rear end portion (base portion) side fixed inside the main body housing 2. The direction of the nozzle unit 11 is not limited to the horizontal direction, and an oblique direction, a vertical direction, or the like can be appropriately selected.

  The nozzle unit 11 has a double nozzle tube structure in which the liquid supply nozzle 16 is fitted to the outside of the suction nozzle 15 so that the suction nozzle 15 and the tip portions 15a and 16a of the liquid supply nozzle 16 are substantially aligned. . A suction passage 15b to which a suction force is applied by the suction pump 10 is formed in the suction nozzle 15 through the suction port 11a, and the liquid tank 12 is provided between the suction nozzle 15 and the liquid supply nozzle 16. A thin ring-shaped liquid supply passage 16b through which the liquid is supplied via the tube 17 is formed.

  At the tip of the suction nozzle 15, there is formed a communication passage 15c that is at least one minute slit that connects the suction passage 15b and the liquid supply passage 16b. For example, as shown in FIG. 4, a plurality (four in this example) of communication paths 15 c are preferably formed at equal angular intervals (90 degrees in this example). As the minute slit, for example, both width and depth are preferably about 0.2 to 0.5 mm. Note that the communication path 15c is not necessarily formed in a slit shape at the tip of the suction nozzle 15. For example, the tip 16a of the liquid supply nozzle 16 is slightly convex than the tip 15a of the suction nozzle 15. It is also possible to form a step (about 0.1 mm).

  If the face device 1 is configured as described above, the two tip portions 15a and 16a of the suction nozzle 15 of the double nozzle tube structure and the liquid supply nozzle 16 are connected to the skin when the skin F is sucked as shown in FIG. When closely attached to F, the suction passage 15b of the suction nozzle 15 to which suction force (see arrow a) is applied by the suction pump 10 becomes negative pressure, so that sebum and dirt are sucked and removed, and the suction nozzle 15 The skin is massaged by moving the tip 15a.

  At the same time, since the negative pressure in the suction passage 15b acts on the liquid tank 12 from the communication passage 15c through the liquid supply passage 16b, the liquid in the liquid tank 12 is transferred to the tube 17 and the liquid as shown by the arrow b in FIG. The suction passage 15b is sucked up from the supply passage 16b through the communication passage 15c.

  At this time, since the communication path 15c is formed at the tip (or the vicinity) of the suction nozzle 15, the liquid sucked up to the communication path 15c is sucked into the suction path 15b by the suction inertia force. The liquid is supplied to the skin F within the tip 16a of the liquid supply nozzle 16 that is in close contact with the skin F (see arrow b '). As a result, an appropriate amount of liquid can be supplied to the surface of the skin F through the communication passage 15c, and the liquid does not scatter outside from the inside of the distal end portion 16a (skin suction portion) of the liquid supply nozzle 16. There will be no waste.

  Further, if the communication path 15c is a minute slit, the amount of liquid supply can be finely adjusted depending on the width, depth, and number, so that the liquid can be supplied in a sprayed state, so that the liquid adheres to the surface of the skin F. Become.

  As shown in detail in FIGS. 5 (a) and 5 (b), it is preferable that the tip portions 15 a and 16 a of the suction nozzle 15 and the liquid supply nozzle 16 are respectively rounded (R). The communication path 15c of the tip portion 15a is a minute slit that is linearly cut in the radial direction. The communication passage 15c may be a minute slit cut in an arch shape in the radial direction, as shown in detail in FIGS.

  Incidentally, as a comparative example, FIG. 2B shows a type in which the communication passage 15 c is not formed at the tip of the suction nozzle 15. In this type, the skin F swollen so as to be sucked into the suction passage 15b of the suction nozzle 15 is in close contact with the tip portion 15a so that the negative pressure of the suction passage 15b does not act up to the liquid supply passage 16b. It is clear that the liquid in the tank 12 cannot be sucked into the suction passage 15b.

  On the other hand, in the type of this embodiment, as shown in FIG. 2A, even if the skin F swollen so as to be sucked into the suction passage 15b of the suction nozzle 15 adheres to the distal end portion 15a without a gap, it continues. Since the passage 15c is not blocked, the negative pressure in the suction passage 15b acts up to the liquid supply passage 16b, so that the liquid in the liquid tank 12 can be sucked into the suction passage 15b.

  In the above embodiment, the rear end (base) side of the nozzle unit 11 is fixed in the main body housing 2. However, as in the embodiment shown in FIGS. The suction nozzle 15 and the liquid supply nozzle 16 having the structure are a nozzle unit 11 that can be attached to and detached from the main body housing 2, and a nozzle / tank unit 20A in which a liquid tank 12 is provided in the nozzle unit 11. it can.

  Specifically, a base member (corresponding to the rear end (base) side of the nozzle unit 11 of the above embodiment) 11A in which the suction port 11a of the nozzle unit 11 is formed in the cylindrical portion 11c is disposed in the main body housing 2. Secure with.

  In addition, an elastic large-diameter base portion 15e having an insertion hole 15d that can be inserted into the cylindrical portion 11c of the base member 11A from the front is formed on the rear end side of the suction nozzle 15, and the large-diameter portion is formed in the main body housing 2. The insertion hole 2b into which the base portion 15e can be inserted from the front is formed. On the outer periphery of the cylindrical portion 11c of the base member 11A, there is provided a seal ring 18 that seals between the insertion hole 15d of the suction nozzle 15 and holds the large diameter base portion 15e so as not to come off.

  Further, the liquid supply nozzle 16 is integrally provided with a liquid tank 12 so as to surround the outer periphery of the nozzle unit 11, and an opening of the bottom of the liquid tank 12 is formed on the flange portion 15f of the large-diameter base 15e with ultrasonic waves or the like. And are integrated in a watertight state.

  In the embodiment shown in FIGS. 6A and 6B, the nozzle unit 11 and the liquid tank 12 are cleaned by using the nozzle / tank unit 20A provided with the liquid tank 12 in the nozzle unit 11, or the liquid tank. When the liquid is replenished to the liquid 12 (the liquid tank 12 has a liquid replenishing port not shown), etc., only the nozzle / tank unit 20A is removed from the main body housing 2 as shown in FIG. Since it is portable, cleaning and replenishment can be performed more easily.

  In particular, by providing the liquid tank 12 so as to surround the outer periphery of the nozzle unit 11, a sufficient capacity of the liquid tank 12 can be ensured, and continuous use for a long time becomes possible.

  Further, both the end portions 15a and 16a of the suction nozzle 15 and the liquid supply nozzle 16 can be provided with roundness (R) as shown in FIGS. 5A and 5B, respectively. As in (b), it is also possible to attach roundness (R) integrally. The outer shape of the liquid tank 12 is most preferably a circular shape when viewed from the front, but various shapes such as an ellipse, a rhombus, a square, a rectangle, a triangle, a hexagon, and a sphere are selected in consideration of design and the like. It is also possible to do.

  In the embodiment of FIGS. 6A and 6B, when the liquid in the liquid tank 12 is reduced and the liquid level (see symbol L in FIG. 7) becomes lower than the rear end portion 16e of the liquid supply passage 16b, the liquid is sucked up. There is a problem that the liquid tank 12 remains as it is (residual water).

  Therefore, as shown in FIG. 7, a flange portion 16c extending to the vicinity of the bottom of the liquid tank 12 is formed at the rear end portion 16e of the liquid supply nozzle 16, and the liquid supply passage 16b is formed inside the flange portion 16c. A straw-shaped suction passage 16d extending from the rear end 16e toward the bottom of the liquid tank 12 is formed. The diameter of the suction passage 16d is preferably φ1.0 or more. A plurality of suction passages 16d may be formed in the circumferential direction, or a tube connected to the rear end portion 16e of the liquid supply passage 16b may be provided.

  In the embodiment of FIG. 7, even if the liquid in the liquid tank 12 decreases and the liquid level L becomes lower than the rear end portion 16e of the liquid supply passage 16b, it can be sucked up by the straw-like suction passage 16d. So there will be no residual water.

  As shown in FIGS. 8A and 8B, instead of forming the flange portion 16c and the suction passage 16d of FIG. 7, the liquid tank 12 is rotatably fitted to the outer periphery of the liquid supply nozzle 16. A semicircular weight (weight) 21 may be provided. In this way, the weight 21 always rotates and stops at the bottom side of the liquid tank 12 due to its own weight. Therefore, even if the liquid level L becomes lower than the rear end portion 16e of the liquid supply passage 16b, the weight 21 Therefore, the liquid level L can be maintained higher than the rear end portion 16e of the liquid supply passage 16b.

  The nozzle / tank unit 20A of the embodiment shown in FIGS. 6 to 8 is integrated in a watertight state by welding the bottom opening of the liquid tank 12 to the flange portion 15f of the large-diameter base portion 15e of the suction nozzle 15 with ultrasonic waves or the like. However, like the nozzle / tank unit 20B of the embodiment shown in FIGS. 9 and 10 (a) and 10 (b), the flange member 22 is welded to the bottom opening of the liquid tank 12 with ultrasonic waves or the like in a watertight state. While fixing, the boss | hub part 15g is protruded from the flange part 15f of the suction nozzle 15 to the front-end | tip direction.

  The flange member 22 is formed with an insertion hole 22a that can be inserted into the boss portion 15g from the front, and a seal ring 23 that seals between the insertion hole 22a is provided on the outer periphery of the boss portion 15g.

  The nozzle / tank unit 20B of the embodiment of FIGS. 9 and 10A and 10B is similar to the nozzle / tank unit 20A of the embodiment of FIGS. When cleaning or replenishing the liquid tank 12, as shown in FIG. 10 (a), since only the nozzle / tank unit 20 can be removed from the main body housing 2 and carried, cleaning and replenishment can be performed more easily. It becomes like this.

  In addition, as shown in FIG. 10B, since the nozzle / tank unit 20B can remove the liquid supply nozzle 16 together with the liquid tank 12 with respect to the suction nozzle 15, the liquid supply passage 16b can be easily cleaned directly. become.

  Here, when the liquid surface in the liquid tank 12 is positioned above the suction nozzle 15 having the double nozzle tube structure and the tip portions 15a and 16a of the liquid supply nozzle 16, or the suction nozzle having the double nozzle tube structure. When 15 and the liquid supply nozzle 16 are directed downward, the liquid in the liquid tank 12 may leak from the tip of the liquid supply passage 16b.

  Therefore, as shown in FIG. 10C, the liquid supply passage 16b is formed in a slit shape extending in the nozzle direction on the outer peripheral surface of the suction nozzle 15 (not shown, but also the inner peripheral surface of the liquid supply nozzle 16). It is formed with a concave groove. The concave grooves are formed in plural (four in this example) at equal angular intervals (90 degrees in this example) on the circumference, but the present invention is not limited to this. Moreover, it is preferable that a ditch | groove has a cross-sectional area equivalent to φ0.2, for example, and it is preferable to select a relatively simple shape such as a circle, an ellipse, a rectangle, and a square as the cross-sectional shape.

  In this way, since the surface tension higher than the head pressure of the liquid in the liquid tank 12 works in the liquid supply passage 16b which is a slit-like concave groove, the liquid surface in the liquid tank 12 has a double nozzle tube structure. Even when the suction nozzle 15 and the tip end portions 15a of the liquid supply nozzle 16 are positioned above the front end portions 15a, 16a or when the suction nozzle 15 and the liquid supply nozzle 16 of the double nozzle tube structure are directed downward, the liquid tank The liquid in 12 does not leak from the tip of the liquid supply passage 16b.

  The liquid supply passage 16b which is such a slit-like concave groove can also be employed in the embodiments of FIGS.
