An opening 14 that opens upward is formed at the front center of the upper surface of the upper housing 13 in the cosmetic body 12. A base member 16 that forms a recess 15 in alignment with the opening 14 is assembled to the upper housing 13.

  A mist nozzle 17 is attached to the base member 16 so as to be rotatable with respect to the cosmetic device body 12 via a support shaft (not shown) as a nozzle rotation shaft. The mist nozzle 17 can be rotated in the vertical direction within a predetermined angle range with respect to the cosmetic body 12. Further, the mist nozzle 17 is integrally formed with a nozzle cover 19 formed so as to cover the periphery of the mist discharge port 18 for discharging the warm mist. Then, by rotating the mist nozzle 17 in the vertical direction, the discharge direction of the warm mist discharged from the mist discharge port 18 can be adjusted in the vertical direction.

  Below the mist outlet 18 in the nozzle cover 19, a substantially U-shaped mist guide 20 in front view is extended in the normal direction of the outer surface of the nozzle cover 19. The mist guide 20 is formed so as to surround the lower side and the left and right sides of the mist discharge port 18, and restricts the user's finger from approaching the mist discharge port 18 from the left and right directions and the lower direction.

  Further, a nozzle guard 21 is attached behind the mist nozzle 17 in the base member 16 as a protector for protecting the mist nozzle 17 so as to be rotatable in the vertical direction. The nozzle guard 21 is formed in a substantially semicircular flat plate shape. The nozzle guard 21 has an open position (second position) where the mist nozzle 17 is exposed as shown in FIG. 1 (a) and the cosmetic device 10 can be used, and a mist nozzle as shown in FIG. 1 (b). It can be turned up and down between a closed position (first position) covering 17.

Next, the piping configuration of the cosmetic device body 12 will be described with reference to FIGS.
As shown in FIG. 2, the cosmetic body 12 is provided with a tank holder 30 that opens on the upper surface of the upper housing 13 and can store the water supply tank 22. A substantially U-shaped drain port 31 is recessed in the back of the tank holder 30. When the water level in the tank holder 30 rises to the bottom of the drain port 31, the water in the tank holder 30 is discharged to the outside through the drain port 31.

  The tank holder 30 is provided with a tank hook 32 for fixing the water supply tank 22. The tank hook 32 is biased toward the tank holder 30 by a spring 33. When the water supply tank 22 is attached to the tank holder 30, the tank hook 32 is engaged with the groove 34 provided on the side surface of the water supply tank 22 based on the urging force from the spring 33, thereby providing the water supply tank. 22 is fixed to the tank holder 30.

  The tank holder 30 is provided with a bearing tube 35 at a lower central position of the water supply tank 22 to be mounted. The bearing tube 35 has a cross-shaped rib 36 extending from front to back and right and left with the outer peripheral surface as a base end, and the tip of the rib 36 is connected to the tank holder 30.

  A lead-out port 37 is formed through the bottom of the tank holder 30, and a supply pipe 38 communicating with the lead-out port 37 is integrally formed forward. A water supply bar 39 penetrating the supply pipe 38 is inserted through the outlet 37. The tip of the water supply bar 39 is inserted and supported so as to be movable in the axial direction in the bearing tube 35. The water supply bar 39 is provided with a water stop packing 40 that closes the outlet 37 of the tank holder 30. A spring 41 is contracted between the water stop packing 40 and the bearing tube 35. Therefore, the water supply bar 39 is urged downward by the elastic force of the spring 41. Therefore, when the beauty device 10 is placed on a horizontal plane, the water supply bar 39 moves up against the elastic force of the spring 41. On the other hand, in a state where the cosmetic device 10 is lifted and not placed on the horizontal plane, the water supply bar 39 moves downward based on the urging force from the spring 41, so that the base end protrudes downward from the bottom of the cosmetic device 10. . When the cosmetic device 10 is placed on a horizontal surface, the water supply bar 39 protruding from the bottom is pushed up and moved upward, so that the outlet 37 is opened as the water-stopping packing 40 moves upward. As a result, the water in the water supply tank 22 is supplied through a supply pipe 38 to a mist generating unit 42 (see FIG. 3) as a mist generating unit.

  An inclination detection micro switch bar 43 is attached to the proximal end portion of the water supply bar 39. The inclination detection micro switch bar 43 moves up integrally with the water supply bar 39 when the water supply bar 39 is pushed in and moves up. When the tilt detection micro switch bar 43 moves up to a predetermined position, the tilt detection micro switch 44 attached to the tank holder 30 detects the tilt detection micro switch bar 43, and the detection signal is transmitted to the control device 45 (FIG. 7). Output). With this configuration, the inclination detection micro switch 44 detects whether or not the water supply bar 39 is pushed in, that is, whether or not the cosmetic device 10 is placed on a horizontal plane. When the detection signal indicating that the cosmetic device 10 is placed on the horizontal plane is not output from the inclination detection microswitch 44, the control device 45 provides a heater 46 (FIG. 3) provided in the mist generation unit 42. (Refer to the above).

  As shown in FIG. 3, the mist generating unit 42 has a mist generating main body 47 made of synthetic resin, and a supply pipe 38 is connected to the lower side of the mist generating main body 47. The mist generating main body 47 is formed with an opening concave portion 49 that is recessed on the left side and opens in the vertical direction. On the right side surface of the mist generating main body 47, a condensate passage 50 extending in the vertical direction is provided. The lower part of the condensate channel 50 communicates with the supply pipe 38. A mist guide tube 51 is connected to the upper portion of the condensate channel 50. The water condensed in the mist guide tube 51 is returned to the condensate channel 50.

  The left opening of the mist generating body 47 is closed by a thin flat plate-like heater 46 extending in the vertical direction. As an example, the heater 46 is composed of a PTC (positive temperature coefficient) element. A space area formed between the heater 46 and the mist generating body 47 is a boiling chamber 53. The lower portion of the boiling chamber 53 communicates with the condensate passage 50 through a lower passage 54 formed below the mist generating body 47. The water sent from the water supply tank 22 to the supply pipe 38 is supplied to the boiling chamber 53 via the condensate channel 50 and the lower channel 54. As a result, the water supplied to the boiling chamber 53 is heated by the heater 46 and boiled to become a high-temperature warm mist.

  A longitudinal groove 55 that widens the opening of the lower passage 54 is formed at the end of the lower passage 54 on the boiling chamber 53 side. As a result, since the capillary force acts on the water in the lower passage 54 so as to flow from the condensate channel 50 side toward the boiling chamber 53 side, the water is suppressed from stagnation in the lower passage 54. .

  A heater packing 56 is provided between the heater 46 and the mist generating body 47, and the boiling chamber 53 is sealed in a watertight manner by the heater packing 56. The heater 46 is provided with a temperature sensor (not shown), and a detection signal from the temperature sensor is output to the control device 45. And the control apparatus 45 stops electricity supply to the heater 46, when a temperature sensor detects temperature more than predetermined.

  Further, a boiler felt 57 having water absorption is provided at the lower part of the boiling chamber 53. The boiler felt 57 is in contact with the heating surface of the heater 46 and absorbs condensed water that hangs down along the wall surface of the boiling chamber 53. The water absorbed by the boiler felt 57 gradually evaporates through the contact surface with the heater 46.

  The upper part of the boiling chamber 53 communicates with the condensate passage 50 through an upper passage 58 formed on the upper side of the mist generating body 47. The warm mist generated in the boiling chamber 53 is supplied to the mist guide cylinder 51 through the condensate channel 50. A boiler mesh 59 is attached to the opening of the upper passage 58 in the boiling chamber 53. The boiler mesh 59 decomposes large bubbles generated by bumping in the boiling chamber 53, thereby suppressing water droplets generated when the bubbles burst from the mist nozzle 17 through the mist guide cylinder 51.

  As shown in FIG. 4, a lower end portion of a bellows member 60 in which a soft material such as silicon rubber is formed in a bellows shape is connected to the upper end portion of the mist guide cylinder 51. Moreover, the upper end part of the bellows member 60 is connected with the nozzle holder 61 formed in the substantially cylindrical shape. The nozzle holder 61 is connected to a substantially annular nozzle packing 62 fixed inside the mist nozzle 17 so as to surround the mist discharge port 18. Therefore, the warm mist generated by the heater 46 is discharged from the mist discharge port 18 through the mist guide cylinder 51 and the bellows member 60.

  As shown in FIG. 2, a discharge part 63 is provided in the mist guide cylinder 51. The discharge unit 63 includes a pair of discharge needles 65 connected to a control circuit 64 (see FIG. 7) and an intermediate electrode 66 disposed between the discharge needles 65. And in the discharge part 63, a warm mist is refined | miniaturized by the high voltage | pressure discharge from the discharge needle 65 installed so that the path | route of mist may be faced. Further, a discharge felt (not shown) having water absorption is provided around the discharge needle 65. The discharge felt absorbs the dew condensation water adhering to the tip of the discharge needle 65, so that the discharge from the discharge needle 65 is favorably performed.

  In addition, a charged fine particle liquid generation mechanism 26 is provided in front of the mist generation unit 42 in the cosmetic device body 12. The charged fine particle liquid generating mechanism 26 is provided with a fan 70, and the fan 70 blows air taken in through an intake port (not shown) to a blower pipe 71 extending upward. In this case, air blown from the fan 70 is sent from the blower pipe 71 to the charged fine particle liquid discharge port 27, but a part of the air is supplied to the electrostatic atomizer 72 through a sub-flow channel (not shown). Then, the electrostatic atomization unit 72 causes the charged fine particle liquid generated by electrostatic atomization to flow back to the blower pipe 71 together with the blown air. As a result, the charged fine particle liquid is ejected from the charged fine particle liquid discharge port 27. A sound deadening material 73 is provided on the inner peripheral surface in the vicinity of the tip of the blower pipe 71.

  Now, in the cosmetic device 10 of the present embodiment, the nozzle guard 21 and the mist nozzle 17 are connected so that the mist nozzle 17 rotates in conjunction with the rotation of the nozzle guard 21.

It is in pressure contact with 90 curved recesses 95.

  In this case, as shown in FIG. 9, the convex portion 112 of the right hinge pin 110 is located at a position deviated rearward with respect to a straight line connecting the shaft portion 111 of the right hinge pin 110 and the convex portion 114 of the cosmetic device body 12. ing. The nozzle guard 21 is held in the closed position by the urging force of the torsion spring 113 that is contracted between the convex portion 112 of the right hinge pin 110 and the convex portion 114 of the cosmetic device body 12.

  Here, when the nozzle guard 21 starts to rotate from the closed position toward the open position, the left hinge pin 82 moves up around the shaft portion 83 in FIG. 8 together with the nozzle guard 21. Then, since the rotation of the left hinge pin 82 is transmitted to the link gear 85 meshing with the left hinge pin 82, the link gear 85 rotates clockwise about the rotation axis S1 in FIG.

  In this case, since the arc 93 of the link gear 85 slides against the curved recess 95 of the extension 90 of the mist nozzle 17, the rotation of the link gear 85 is not transmitted to the extension 90 of the mist nozzle 17. . Therefore, the rotation of the nozzle guard 21 is not transmitted to the mist nozzle 17, and the nozzle guard 21 rotates independently of the mist nozzle 17. In the movable range in which the nozzle guard 21 rotates independently of the mist nozzle 17, the arcuate portion 93 of the link gear 85 is kept in pressure contact with the curved recess 95 of the extension portion 90 of the mist nozzle 17. The Therefore, the link gear 85 restricts the mist nozzle 17 from rotating about the rotation axis S2.

  Then, as shown in FIG. 10, when the link gear 85 further rotates in conjunction with the rotation operation of the nozzle guard 21, the inner surface of the concave groove 94 of the link gear 85 is provided in the extending portion 90 of the mist nozzle 17. The convex portion 96 is engaged in the circumferential direction around the rotation axis S2. As a result, the rotation of the link gear 85 is transmitted to the extending portion 90 of the mist nozzle 17 through the convex portion 96. Therefore, the mist nozzle 17 moves upward about the rotation axis S <b> 2 in FIG. 10 so as to eliminate the pressure contact state between the arc portion 93 of the link gear 85 and the curved concave portion 95 of the extension portion 90. That is, the rotation position of the nozzle guard 21 shown in FIG. 10 is a boundary position between a movable range that rotates independently of the mist nozzle 17 and a movable range that rotates in conjunction with the mist nozzle 17.

  In this case, the convex portion 96 of the extending portion 90 approaches the rotational axis S <b> 1 of the link gear 85 as the mist nozzle 17 rotates, but between the convex portion 96 and the inner bottom surface of the concave groove 94. Since a gap is interposed between the convex portion 96 and the concave portion 94, the convex portion 96 moves to the inner depth side. Therefore, the concave groove 94 prevents the convex portion 96 from interfering with the rotation of the link gear 85.

  When the nozzle guard 21 rotates to the position shown in FIG. 10, the engagement piece 98 that rotates together with the link gear 85 is detected by the open / close detection microswitch 99, and the open / close detection microswitch 99 controls the control device 45. An open signal is output at. Then, the control device 45 allows the heater 46 and the discharge unit 63 to be energized when an open signal is input from the open / close detection microswitch 99.

  Further, when the nozzle guard 21 rotates to the position shown in FIG. 10, the protrusion 100 of the link gear 85 rides on the convex portion 101 provided on the cosmetic body 12, thereby causing a feeling of resistance (click feeling) in the operation. Therefore, in the present embodiment, the resistance generated when the nozzle guard 21 passes through the boundary position between the movable range that rotates independently of the mist nozzle 17 and the movable range that rotates in conjunction with the mist nozzle 17. The feeling (click feeling) recognizes that the warm mist can be released.

  In this case, as shown in FIG. 11, the convex portion 112 of the right hinge pin 110 is arranged on a straight line connecting the shaft portion 111 of the right hinge pin 110 and the convex portion 114 of the cosmetic device body 12. Therefore, since the distance between the convex portion 112 of the right hinge pin 110 and the convex portion 114 of the cosmetic device body 12 is the shortest distance, the opening angle of the torsion spring 113 is minimum. That is, while the nozzle guard 21 is rotated from the closed position to the boundary position, the torsion spring 113 is compressed so that the opening angle is reduced, so that the nozzle guard 21 is held at the closed position by the urging force from the torsion spring 113. The Therefore, in the present embodiment, by maintaining the closed state when the cosmetic device 10 is not used, it is possible to satisfactorily suppress foreign matters such as dust from adhering to the mist nozzle 17.

  Further, as shown in FIG. 12, when the link gear 85 further rotates in conjunction with the rotation operation of the nozzle guard 21, the second tooth portion 92 of the link gear 85 is provided in the extension portion 90 of the mist nozzle 17. Engage with the tooth portion 91. Then, since the rotation of the link gear 85 is transmitted to the extending portion 90 of the mist nozzle 17 meshed with the link gear 85, the mist nozzle 17 further moves up around the rotation axis S2 in FIG. That is, the nozzle guard 21 rotates in conjunction with the mist nozzle 17 at the rotation position of the nozzle guard 21 shown in FIG.

  In this case, as shown in FIG. 13, the convex portion 112 of the right hinge pin 110 is disposed at a position deviated forward with respect to a straight line connecting the shaft portion 111 of the right hinge pin 110 and the convex portion 114 of the cosmetic device body 12. The Therefore, the distance between the convex portion 112 of the right hinge pin 110 and the convex portion 114 of the cosmetic device body 12 is larger than when the nozzle guard 21 is disposed at the boundary position, so that the opening angle of the torsion spring 113 is increased. . That is, while the nozzle guard 21 is rotated from the boundary position to the open position, the torsion spring 113 is elastically returned so that the opening angle increases, so that the nozzle guard 21 is held in the open position by the urging force from the torsion spring 113. Is done. Therefore, in the movable range in which the nozzle guard 21 rotates in conjunction with the mist nozzle 17, the torsion spring 113 pushes up the nozzle guard 21 from below against its own weight, so that the rotation (upward movement) of the nozzle guard 21 is performed. Assisted by a torsion spring 113.

  By the way, in the present embodiment, in the movable range in which the nozzle guard 21 rotates in conjunction with the mist nozzle 17, when the left hinge pin 82 rotates as the nozzle guard 21 rotates, the left hinge pin 82 rotates. This is transmitted to the extension 90 of the mist nozzle 17 via the link gear 85. In this case, the link gear 85 rotates around the rotation axis S1 without being displaced in a direction intersecting with the rotation axis S1. Therefore, it is not necessary to secure a space area for allowing the link gear 85 to pass in the direction intersecting the rotation axis S1 during the rotation operation of the nozzle guard 21, thereby saving the space of the entire apparatus. . In this case, the direction in which the warm mist is discharged from the mist nozzle 17 is adjusted by rotating the nozzle guard 21. Therefore, the user's finger is prevented from approaching the mist nozzle 17 when adjusting the discharge direction of the warm mist.

According to the above embodiment, the following effects can be obtained.
(1) When the nozzle guard 21 is rotated, the rotation of the left hinge pin 82 that rotates integrally with the nozzle guard 21 is transmitted to the extending portion 90 of the mist nozzle 17 via the link gear 85. Therefore, the nozzle guard 21 and the mist nozzle 17 can be operated in conjunction with each other. In this case, the link gear 85 rotates about the rotation axis S1 without being displaced in a direction intersecting the axis direction of the rotation axis S1. Therefore, it is not necessary to secure a space area for allowing the link gear 85 to pass in the direction intersecting the rotation axis S1 during the rotation operation of the nozzle guard 21, thereby suppressing the increase in size of the entire apparatus. it can.

  (2) Since the link gear 85 is drivingly connected by meshing with the extension portion 90 of the left hinge pin 82 and the mist nozzle 17, the rotation of the left hinge pin 82 is rotated via the link gear 85. Can be reliably transmitted to the extending portion 90.

  (3) When the nozzle guard 21 rotates from the closed position toward the open position, first, the arc portion 93 of the link gear 85 is disposed so as to face the extending portion 90 of the mist nozzle 17. Therefore, even if the link gear 85 rotates in conjunction with the left hinge pin 82 when the nozzle guard 21 rotates, the rotation of the link gear 85 is not transmitted to the extending portion 90 of the mist nozzle 17. Therefore, the nozzle guard 21 and the mist nozzle 17 can be operated independently. When the nozzle guard 21 further rotates from the closed position toward the open position, the second tooth portion 92 of the link gear 85 meshes with the extension portion 90 of the mist nozzle 17. Therefore, when the link gear 85 rotates in conjunction with the left hinge pin 82 during the rotation of the nozzle guard 21, the rotation of the link gear 85 is transmitted to the extending portion 90 of the mist nozzle 17. Therefore, the nozzle guard 21 and the mist nozzle 17 can be operated in conjunction with each other. That is, the nozzle guard 21 has a movable range that operates independently of the mist nozzle 17 and a movable range that operates in conjunction with the mist nozzle 17. Therefore, compared with the case where the nozzle guard 21 and the mist nozzle 17 operate in conjunction with each other over the entire movable range of the nozzle guard 21, the movable range of the mist nozzle 17 can be narrowed. The configuration can be made compact.

  (4) When the nozzle guard 21 is rotated from the closed position toward the open position, the convex portion 96 of the extending portion 90 engages with the inner surface of the concave groove 94 of the link gear 85. Therefore, when the link gear 85 rotates in conjunction with the left hinge pin 82 during the rotation of the nozzle guard 21, the rotation of the link gear 85 is transmitted to the extending portion 90 via the convex portion 96. In this case, since there is a gap between the convex portion 96 and the inner bottom surface of the concave groove 94, the convex portion 96 is rotated so as to approach the rotational axis S1 of the link gear 85. Even if it exists, it is avoided by the ditch | groove 94 that the convex part 96 interferes with rotation of the link gear 85. FIG. Therefore, the rotation of the link gear 85 is transmitted to the extending portion 90 via the protruding portion 96 so as to surely engage the second tooth portion 92 of the link gear 85 with the extending portion 90, and this protruding portion 96. It can suppress that rotation of the link gear 85 interferes due to.

  (5) When the meshing position of the left hinge pin 82 and the link gear 85 deviates from a desired position, the front side of the left hinge pin 82 is moved when the nozzle guard 21 is rotated from the closed position toward the open position. The tooth portion 84 a tries to mesh with the rear side tooth groove 87 b of the link gear 85. In this case, the front tooth portion 84a whose tooth width is set to be relatively large in the left hinge pin 82 can mesh with the rear tooth groove 87b whose groove width is set to be relatively small in the link gear 85. Can not. Therefore, when the apparatus is assembled, the tooth portion and the tooth gap determined with each other can be reliably engaged with each other, so that the nozzle guard 21 and the mist nozzle 17 can be accurately interlocked.

In addition, you may change the said embodiment into another embodiment as follows.
In the above embodiment, the left hinge pin 82 may be set such that the front tooth portion 84a has a smaller tooth width in the axial direction of the shaft portion 83 than the rear tooth portion 84b. Further, the left hinge pin 82 may have the same tooth width in the axial direction of the shaft portion 83 of the front side tooth portion 84a and the rear side tooth portion 84b.

  In the embodiment described above, the extended portion 90 of the mist nozzle 17 may not be provided with the curved concave portion 95. In this case, the link gear 85 does not need to be provided with the concave groove 94 as an interference avoidance shape for avoiding interference by the convex portion 96 provided at the rear end portion of the curved concave portion 95.

  In the above embodiment, the arc 93 of the link gear 85 is second in the rotation direction of the link gear 85 that rotates in conjunction with the left hinge pin 82 when the nozzle guard 21 rotates from the closed position to the open position. It may be arranged on the rear side in the rotation direction with respect to the tooth portion 92.

  In the above-described embodiment, the nozzle guard 21 is always meshed with the link gear 85 and the extending portion 90 of the mist nozzle 17 throughout the movable range of the nozzle guard 21 without providing the link gear 85 with the arc portion 93. The nozzle guard 21 and the mist nozzle 17 may operate in conjunction with each other over the entire movable range.

  In the above embodiment, the link gear 85 meshes with the left hinge pin 82 and the other gear that is drivingly connected to the extension portion 90 without meshing with the left hinge pin 82 and extension portion 90. And it is good also as a structure drive-coupled with respect to the extension part 90. FIG.

  In the above embodiment, the mist generating unit 42 generates the warm mist. However, for example, the mist generating unit 42 may generate a cold mist having a temperature lower than that of the warm mist. In this case, cold mist is discharged from the mist nozzle 17.

In the above embodiment, one mist nozzle 17 that discharges warm mist is provided, but two or more mist nozzles 17 may be provided.
In the above embodiment, in combination with the mist nozzle 17, a nozzle that discharges negative ions and positive ions, a nozzle that discharges a chemical such as a moisturizer and a whitening agent, a nozzle that discharges a charged fine particle liquid, and the like are provided. It may be. In this case, if the nozzle guard 21 is provided at least with respect to the mist nozzle 17, the same effect as that of the above embodiment can be obtained.

  In the above embodiment, a liquid containing a moisturizer or a whitening agent or a liquid containing a fragrance may be stored in the water supply tank 22 as a liquid for heating the heater 46 to generate warm mist.
