Description

Cosmetic device and cosmetic method

Technical Field

The present invention relates to a cosmetic device and a cosmetic method.

Background

In japanese patent laid-open No. 10-263044, there is proposed a cosmetic device comprising: a container for storing a liquid; an ejection port for ejecting the liquid in the container to the outside; and a piston pump provided in the middle of the flow path from the container to the discharge port.

In the above document, the liquid in the container is discharged from the discharge port in the form of a pulsating jet flow by operating the piston pump. Further, the pulsating jet flow discharged from the discharge port contacts the scalp and the like, whereby dirt (for example, sebum, keratotic plug, dirt and the like) adhering to the scalp and the like in the pores can be removed.

Disclosure of Invention

However, sebum, keratotic plugs, dirt, and the like are usually retained in the pores in a complex mixture. Therefore, as in the conventional technique, dirt remaining in a state of complicated mixing cannot be efficiently removed by simply bringing the pulsating jet flow into contact with the scalp or the like.

The present invention has been made to solve the above-described conventional problems, and an object thereof is to provide a cosmetic device and a cosmetic method capable of removing dirt in pores more efficiently.

In order to achieve the above object, a cosmetic device of the present invention includes: an alkaline liquid storage unit for storing an alkaline liquid to be supplied to the skin of a user; an alkaline liquid passage having an alkaline liquid discharge port through which the alkaline liquid stored in the alkaline liquid storage unit is discharged; and an alkaline liquid ejecting mechanism that can eject the alkaline liquid toward the skin of the user.

Further, a plurality of programs are set, and the programs can remove dirt on the skin of the user by ejecting the alkaline solution.

If a plurality of programs are set as described above, which can remove dirt on the skin of the user by ejecting the alkaline solution, for example, a program for softening the dirt on the skin, a program for removing the softened dirt, and the like can be set, and the dirt on the pores can be more efficiently removed.

Further, the cosmetic method of the present invention is a method performed using the cosmetic device.

The cosmetic method includes an alkaline liquid supply step of supplying the alkaline liquid to the skin of the user by ejecting the alkaline liquid at a predetermined flow rate to the skin of the user by the alkaline liquid ejection mechanism.

The cosmetic method further includes a skin washing step of, after the alkaline liquid supply step, spraying the alkaline liquid at a flow rate higher than the predetermined flow rate to the skin of the user by the alkaline liquid spray mechanism, thereby washing the skin of the user.

This makes it possible to remove dirt that has accumulated in pores or the like while softening the dirt, and thus more efficiently remove dirt that has accumulated in pores or the like.

According to the present invention, a cosmetic device and a cosmetic method capable of more efficiently removing dirt in pores can be obtained.

Detailed Description

The cosmetic device of an embodiment of the present invention includes: an alkaline liquid storage unit for storing an alkaline liquid to be supplied to the skin of a user; an alkaline liquid passage having an alkaline liquid discharge port through which the alkaline liquid stored in the alkaline liquid storage unit is discharged; and an alkaline liquid ejecting mechanism that can eject the alkaline liquid toward the skin of the user.

When the dirt on the skin of the user is removed by ejecting the alkaline liquid as described above, the alkaline liquid can promote hydrolysis of sebum, keratin, and other proteins retained in pores, and soften the dirt retained in pores. Therefore, dirt accumulated in pores and the like can be more easily removed. Further, if a plurality of programs are set as the program for removing the dirt on the skin of the user by ejecting the alkaline solution, for example, a program for softening the dirt on the skin, a program for removing the softened dirt, and the like can be set, and the dirt on the pores can be more efficiently removed.

Further, the program may have: a first program for ejecting the alkaline solution at a predetermined flow rate; and a second process of ejecting the alkaline liquid at a flow rate higher than the ejection flow rate of the alkaline liquid in the first process.

If the procedure for removing the dirt on the skin of the user by discharging the alkaline solution as described above is made to have two procedures with different discharge rates of the alkaline solution, the discharge rate of the alkaline solution can be switched according to the procedures such as the supply of the alkaline solution to the skin and the removal of the dirt on the pores by the alkaline solution. As a result, the dirt in the pores can be removed more efficiently.

Further, the first program may be performed before the second program.

In this way, after the alkaline solution is supplied to the skin by the first process having a relatively low discharge rate, the pore dirt can be removed by the second process having a relatively high discharge rate. As a result, the dirt in the pores can be removed more efficiently.

Further, in order to efficiently remove the dirt in the pores, it is conceivable to further increase the discharge rate of the alkaline solution to the skin, but when the alkaline solution is discharged using only one program, the discharge rate becomes too high, which may cause irritation to the skin. In contrast, if the first program in which the ejection speed is low is followed by the second program in which the ejection speed is high, the dirt in the pores can be removed without increasing the ejection speed to the skin in the second program to a necessary speed or more. Therefore, the skin irritation can be suppressed as much as possible, and the dirt in the pores can be removed more efficiently.

The first program may be set to end when a timer incorporated therein counts a predetermined time.

Thus, the use method is simple, and the use convenience of the beauty device can be further improved.

In addition, if the first program is ended using the timer, it is possible to suppress the time taken for the first program from being lengthened or shortened to be longer than or shorter than necessary.

In addition, if the time taken for the first procedure is extended to be longer than necessary, the time taken for the cosmetic device to be used may be increased, and a large amount of alkaline solution may be consumed when the first procedure is performed. On the other hand, if the time taken for the first process is shortened to the required time or less, the time required for the alkaline solution to chemically react with the scale (the time required for softening the scale) cannot be ensured, and the effect of removing pore scale may be reduced.

However, if the timer is used to end the first routine, it is possible to ensure the time required for the alkaline solution to chemically react with the scale without taking more time than necessary. That is, the time for the first program to be executed can be set to a more appropriate time.

This can shorten the use time of the cosmetic device and further improve the effect of removing pore dirt.

Further, by shortening the use time of the cosmetic device, the amount of the alkaline liquid, the electric power, and the like consumed when the first program is performed can be suppressed, and thus wasteful consumption of the alkaline liquid and the electric power can be suppressed. By reducing the use time as described above, the consumption of the alkaline solution and the electric power is suppressed, and the cost for one-time use can be reduced.

Further, a cleaning button for ejecting the alkaline solution may be provided, and the alkaline solution may be ejected only when the cleaning button is operated.

In this way, since the alkaline liquid can be discharged at the will of the user, the alkaline liquid can be prevented from being accidentally discharged in a state where the alkaline liquid discharge port does not face the skin. That is, the alkaline liquid can be more reliably prevented from scattering to the surroundings when the cosmetic device is used. As a result, the cosmetic device can be used more securely, and the convenience of use of the cosmetic device can be further improved.

Further, the cosmetic method of the embodiment of the present invention is performed using the cosmetic device.

The cosmetic method further includes a skin washing step of washing the skin of the user by ejecting the alkaline liquid to the skin of the user at a flow rate higher than the predetermined flow rate by the alkaline liquid ejecting mechanism after the alkaline liquid supplying step.

In this way, after the dirt accumulated in the pores or the like is softened by the alkaline liquid supplied to the skin in the alkaline liquid supply step, the softened dirt can be removed by the alkaline liquid discharged in the skin washing step, and therefore the dirt in the pores can be more efficiently removed. In addition, in the skin washing step, since the softened dirt is removed, the dirt can be removed without increasing the ejection speed of the alkaline solution more than necessary. Therefore, the skin irritation can be suppressed as much as possible, and the dirt in the pores can be removed more efficiently.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiment.

In addition, the side where the alkaline liquid discharge port is located in normal use will be defined as the upper side of the beauty treatment apparatus as follows.

(embodiment mode 1)

As shown in fig. 1A, 1B, 1C, and 2, the cosmetic device 10 according to embodiment 1 includes: a main body 20 having a grip 21 a; a container case 30 detachably attached to a lower portion of the main body 20; and a nozzle unit 40 detachably attached to an upper portion of the body unit 20.

The cosmetic device 10 is a device as follows: the alkaline liquid L1 stored in the container case 30 is discharged toward the skin S of the user U from the alkaline liquid discharge port 80a formed on the distal end side of the nozzle unit 40, thereby removing dirt adhering to the skin S of the user U. When the alkaline liquid L1 is discharged to the skin S of the user U as described above, the alkaline liquid L1 promotes the hydrolysis of proteins such as sebum and keratotic plugs attached to the pores of the skin S of the user U, thereby softening dirt accumulated in the pores. Therefore, dirt accumulated in pores and the like can be more easily removed.

Hereinafter, a specific configuration of the beauty treatment apparatus 10 according to embodiment 1 will be described.

The main body portion 20 includes an elongated substantially cylindrical housing 21 made of insulating synthetic resin, and main components are housed in the cylinder of the housing 21.

A grip portion 21a is formed at a substantially central portion in the longitudinal direction of the housing 21. In embodiment 1, a concave portion 21b curved so as to protrude inward is formed in a substantially central portion in the longitudinal direction of the housing 21, that is, in a rear portion (a rear surface side of the cosmetic device 10) of a portion of the housing 21 which becomes the grip portion 21 a. By forming the concave portion 21b as described above, the portion of the housing 21 to be the grip portion 21a is made thin, and the grip portion 21a is formed in a shape that can be easily gripped by a hand.

In embodiment 1, a flat surface is formed at the bottom of the beauty treatment apparatus 10 in a state where the container case 30 is attached to the housing 21, and the beauty treatment apparatus 10 can be left standing in a posture where the nozzle portion 40 is located upward when not in use.

An upper opening 21c is formed at the upper end of the housing 21, and the nozzle body 41 of the nozzle unit 40 is inserted into the upper opening 21c, whereby the nozzle unit 40 can be detachably attached to the upper portion of the body 20. In embodiment 1, a push button 22 that can be inserted and projected is attached to an upper end portion of the back surface side of the casing 21, and the coupling between the main body portion 20 (casing 21) and the nozzle portion 40 can be released by operating (for example, pressing) the push button 22. The method of attaching and detaching the nozzle portion 40 to and from the body portion 20 is not limited to this, and various methods can be employed. For example, the screwing method may be a screwing method in which the nozzle portion 40 is screwed into the upper portion of the body portion 20 to attach the nozzle portion 40 to the body portion 20.

On the other hand, a lower opening 21d is formed in the lower end portion of the outer case 21, and the tank case 30 is inserted into the lower opening 21d from below, whereby the tank case 30 can be detachably attached to the lower portion of the main body portion 20. The container case 30 is formed in a bottomed cylindrical shape and has a bottom wall portion 31 and a peripheral wall portion 32, the peripheral wall portion 32 is provided to extend upward from a peripheral edge portion of the bottom wall portion 31, and an alkaline solution storage portion 33 for storing alkaline solution L1 is formed inside the container case 30.

As described above, the container case 30 is detachably attached to the lower portion of the main body portion 20, and the alkaline liquid L1 is stored in the alkaline liquid storage portion 33 in a state where the container case 30 is detached from the main body portion 20. Further, by inserting the container case 30 in which the alkaline liquid L1 is stored into the lower opening 21d from below, the alkaline liquid L1 can be stored in the cosmetic device 10. In embodiment 1, the alkaline solution L1 that can be stored in the alkaline solution storage unit 33 is set to a capacity of about 80ml, so that the user U can use the alkaline solution easily even if the user U is a woman or an elderly person. In embodiment 1, the container case 30 is formed to be transparent or translucent, and the liquid level window 23 which is elongated in the vertical direction is provided in a portion of the housing 21 where the container case 30 is attached, whereby the liquid level of the alkaline liquid L1 in the container case 30 can be confirmed from the outside. In embodiment 1, the container case 30 is formed in a shape having a large upper opening, and the inside of the container case 30 can be easily cleaned.

The alkaline liquid L1 stored in the alkaline liquid storage 33 can be generated by, for example, adding an alkaline concentrated solution L2 for pH adjustment and supplying a liquid L3 such as tap water. As the liquid L3 to be supplied, a liquid at normal temperature can be used, but a liquid heated to about 40 ℃. When a liquid at about 40 ℃ is supplied, the decomposition of protein can be further promoted, and thus the cleaning power (dirt removing power) can be further improved. The method of storing the alkaline solution L1 in the alkaline solution storage 33 is not limited to the above method, and for example, the alkaline solution L1 prepared in advance may be directly stored in the alkaline solution storage 33. At this time, the alkali solution L1 prepared in advance may be heated and stored in the alkali solution storage unit 33.

Further, it is preferable that the pH of the alkaline solution L1 stored in the alkaline solution storage part 33 is in the range of 9 to 12. This is because if the pH of the alkaline solution L1 is within the above range, irritation to the eyes and skin S of the user U can be suppressed.

The alkaline concentrate L2 can be, for example, a liquid containing water as a main component, about 0.1 wt% of trisodium phosphate, about 1 wt% of sodium dihydrogen phosphate, about 3 wt% of propylene glycol. That is, an alkaline concentrated solution L2 can be produced by blending (dissolving) about 0.1 wt% of trisodium phosphate, about 1 wt% of sodium dihydrogen phosphate, and about 3 wt% of propylene glycol in water as a main component. The pH of the alkaline concentrate L2 thus produced was about 10.7.

When the alkaline concentrated solution L2 is supplied with a liquid L3 such as tap water to produce an alkaline solution L1, the use of trisodium phosphate and sodium dihydrogen phosphate can produce an alkaline solution L1 having a pH of about 10.5 (a pH in the range of 9 to 12) in a relatively small amount. When the amount of the reagent used for producing the alkaline liquid L1 is reduced as described above, it is possible to suppress the occurrence of: the alkaline liquid passage 80 and the alkaline liquid ejection port 80a are blocked by recrystallization of the reagent generated when the liquid in the alkaline liquid passage 80 is dried, which will be described later.

Further, by using trisodium phosphate and sodium dihydrogen phosphate, an alkaline solution L1 having excellent pH buffering ability can be formed. That is, the alkaline liquid L1 produced by mixing the above components becomes a liquid having a pH buffering ability.

As described above, when the alkaline liquid L1 having pH buffering ability is used in the cosmetic device 10, it is possible to suppress the change in pH of the alkaline liquid due to the state of the skin S to be supplied (the pH of the skin S). That is, the pH of the alkaline liquid L1 in the state of being supplied to the skin S does not greatly deviate from the value at the time of production of the alkaline liquid L1 (about 10.5 for the alkaline liquid L1 containing the above components) regardless of the state of the skin S before being supplied with the alkaline liquid L1 (the pH of the skin S).

As described above, by reducing the change in pH of the alkaline liquid L1 in the state of being supplied to the skin S as much as possible, it is possible to suppress a decrease in cleaning force due to the change in pH of the alkaline liquid L1. That is, if the alkaline solution L1 has a pH buffering capacity, a more stable cleaning force can be ensured.

Further, when a liquid having a pH buffering ability is used as the alkaline liquid L1, since the change in pH occurring when the alkaline liquid L1 is diluted can be reduced as much as possible, the skin can be cleaned (the dirt can be removed) using the diluted alkaline liquid L1. When the skin S can be cleaned using the diluted alkaline liquid L1 as described above, the amount of the reagent used in one cleaning can be further reduced, and therefore, the alkaline liquid passage 80 and the alkaline liquid ejection port 80a can be further prevented from being clogged.

When the alkaline solution L1 is diluted with water, normal temperature water can be used, but warm water at about 40 ℃. When the alkaline solution L1 is diluted with warm water of about 40 ℃, the decomposition of protein can be further promoted, and thus the detergency can be further improved.

Further, since the alkaline concentrated solution L2 also has a pH buffering capacity, when the alkaline concentrated solution L1 is generated by supplying the liquid L3 such as tap water to the alkaline concentrated solution L2, there is an advantage that the liquid L3 supplied is less likely to be affected.

Since propylene glycol has liquid antibacterial activity and skin moisturizing activity, both antibacterial components and moisturizing components are contained in the propylene glycol-blended alkaline solution L1.

As described above, when the liquid containing propylene glycol is used as the alkaline liquid L1, the storage performance of the alkaline liquid L1 can be improved, and the irritation to the skin S to which the alkaline liquid L1 is supplied (the skin S after use) can be reduced.

In addition, if propylene glycol having an antibacterial action of a liquid and a moisturizing action of the skin is used, that is, if the same component is used as the antibacterial component and the moisturizing component, the kind and amount of the blended agent can be reduced. As a result, the occurrence of the following can be suppressed: the alkaline liquid passage 80 and the alkaline liquid ejection port 80a are blocked by recrystallization of the reagent generated when the liquid in the alkaline liquid passage 80 is dried. Further, the productivity of the alkaline solution L1 can be improved.

The alkaline solution L1 may contain other components than the above components. The alkaline solution L1 can be produced using various components other than the above components, for example, a combination of sodium carbonate and sodium hydrogen carbonate, a combination of disodium pyrophosphate and trisodium pyrophosphate, sodium propionate, AMPD (2-amino-2-methyl-1, 3-propanediol), and the like.

In the cosmetic device 10, an alkaline liquid passage 80 through which the alkaline liquid L1 stored in the alkaline liquid storage 33 passes is formed, and a downstream end of the alkaline liquid passage 80 is an alkaline liquid discharge port 80a through which the alkaline liquid L1 is discharged to the outside of the cosmetic device 10. That is, the alkaline liquid L1 stored in the alkaline liquid storage 33 is discharged from the alkaline liquid discharge port 80a through the alkaline liquid passage 80.

In embodiment 1, an alkaline liquid discharge mechanism for discharging the alkaline liquid L1 stored in the alkaline liquid storage 33 toward the skin S of the user U is provided in the cosmetic device 10, and the alkaline liquid L1 is discharged from the alkaline liquid discharge port 80a by the alkaline liquid discharge mechanism.

Specifically, a pump section 50 as an alkaline liquid ejecting mechanism is provided in the middle of the alkaline liquid passage 80, and the alkaline liquid L1 stored in the alkaline liquid storage section 33 is ejected from the alkaline liquid ejecting port 80a by operating the pump section 50.

In embodiment 1, the pump section 50 is incorporated in the main body section 20, and the pump section 50 includes a diaphragm pump 51 having a small size and a high discharge force. The pump section 50 includes an electric motor 52 that can drive a diaphragm pump 51. Instead of the diaphragm pump 51, a piston pump may be used.

The electric motor 52 is electrically connected to a battery 60 as a power source, and the electric motor 52 is driven by electric power of the battery 60. The socket 61 is electrically connected to the battery 60, and the battery 60 is charged by supplying power from an external power supply, not shown, such as an AC adapter through the socket 61. In embodiment 1, normally, socket 61 is covered with cover 24, and battery 60 is charged by removing cover 24 and connecting socket 61 to an external power supply, not shown, such as an AC adapter.

As described above, in embodiment 1, since the pump section 50 as the alkaline liquid discharge mechanism is provided in the middle of the alkaline liquid passage 80, the alkaline liquid passage 80 has the suction-side passage 81 for supplying the alkaline liquid L1 stored in the alkaline liquid storage section 33 to the pump section 50. A mesh-like filter 81a is provided at the tip (upstream end) of the suction-side passage 81, and foreign matter can be prevented from entering the alkaline solution passage 80.

The alkaline liquid passage 80 has an alkaline liquid discharge port 80a, and a discharge-side passage 82 into which the alkaline liquid L1 in the pump section 50 is introduced. The discharge-side passage 82 is constituted by a casing inner passage 82a provided in connection with the downstream side of the pump portion 50, and a nozzle inner passage 82b communicating with the downstream side of the casing inner passage 82a when the nozzle portion 40 is mounted on the upper portion of the body portion 20. An alkaline solution ejection port 80a is formed in a downstream side portion of the nozzle internal passage 82 b.

As shown in fig. 2 and 3, the nozzle unit 40 is detachably attached to the tip end (the side from which the alkaline liquid L1 is discharged) of the body 20, and the nozzle unit 40 includes a nozzle body 41 that is insertable into the upper opening 21c of the body 20. The nozzle body 41 is formed with an alkaline solution discharge port 80a and an internal nozzle passage 82b near the alkaline solution discharge port 80 a.

Fig. 3 shows the entire nozzle unit 40, and also shows a grip portion (a portion engaged with the upper opening 21c of the body 20) of the nozzle body 41.

The nozzle portion 40 includes a substantially cylindrical coupling member 42. The coupling member 42 has an internal space (a part of the nozzle internal passage 82 b) that is connected to the nozzle internal passage 82b of the nozzle body 41 and is connected to the downstream side of the casing internal passage 82a in a state where the nozzle portion 40 is attached to the upper portion of the body 20. Further, the coupling member 42 can be detachably attached to the nozzle body 41, and the nozzle inner passage 82b can be easily cleaned.

The nozzle unit 40 includes a skin contact portion 43 that contacts the skin S of the user U when the cosmetic device 10 is used. The skin contact portion 43 is attached to the tip side (the side from which the alkaline solution L1 is discharged) of the handle portion of the nozzle body 41. Further, the skin contact portion 43 is also detachably attached to the nozzle body portion 41, and the skin contact portion 43 can be easily cleaned.

In embodiment 1, the filter 44 is provided upstream of the coupling member 42, and can prevent the alkaline liquid discharge port 80a from being clogged with foreign matter. The filter 44 is detachably attached to the upstream side of the coupling member 42, and the filter 44 can be cleaned in a state where the filter 44 is removed from the coupling member 42. Further, the filter 44 may be integrated with the coupling member 42.

Two alkaline solution discharge ports 80a are formed in the nozzle body 41. In embodiment 1, the two alkaline liquid discharge ports 80a are formed to be aligned in the horizontal direction at a pitch of about 1.5mm when the nozzle unit 40 is viewed from the front (when the nozzle unit 40 is viewed from the front in a state where the beauty apparatus 10 is disposed such that the nozzle unit 40 is positioned upward). Further, each of the alkaline liquid spouting ports 80a is formed as a hole having a diameter of about 0.16 mm.

When the two alkaline liquid discharge ports 80a are formed so as to be aligned in the horizontal direction when the nozzle unit 40 is viewed from the front as described above, the alkaline liquid discharge ports 80a can be formed below the interference region R where the alkaline liquid L1 interferes when discharged (see fig. 8).

As shown in fig. 9, when the three alkaline liquid discharge ports 80a are arranged at equal intervals in the circumferential direction, the alkaline liquid discharge ports 80a are formed below the interference region R where interference occurs when the alkaline liquid L1 is discharged. When the alkaline liquid discharge port 80a is formed below the interference region R as described above, the discharge of the alkaline liquid L1 from the alkaline liquid discharge port 80a located below the interference region R may be hindered by the alkaline liquid L1 falling from the interference region R.

On the other hand, as in embodiment 1, if the alkaline liquid discharge ports 80a are not formed below the interference region R, it is possible to suppress the discharge of the alkaline liquid L1 from one alkaline liquid discharge port 80a from being hindered by the alkaline liquid L1 discharged from the other alkaline liquid discharge port 80 a. This enables the alkaline liquid L1 to be ejected from each alkaline liquid ejection port 80a more efficiently and continuously.

In addition, only one alkaline solution discharge port 80a may be provided, or three or more may be provided. When three or more alkaline liquid discharge ports 80a are provided, as described above, the alkaline liquid discharge ports 80a are preferably not formed below the interference region R.

In embodiment 1, the pitch between the two alkaline solution discharge ports 80a is about 1.5mm, but the pitch may be larger than 1.5mm or smaller than 1.5 mm. However, if the gap is too small, each of the alkaline liquid discharge ports 80a is likely to be interfered with by another alkaline liquid discharge port 80a, and therefore, it is preferable that the two alkaline liquid discharge ports 80a be formed in a state separated from each other so as not to be interfered with by another alkaline liquid discharge port 80a as much as possible. Further, if the pitch is too large, the skin contact portion 43 becomes large, and the usability of the cosmetic device 10 is degraded, so it is preferable not to excessively increase the pitch.

In embodiment 1, the aperture (diameter) of the alkaline liquid discharge port 80a is formed to be smaller than the diameter of a general pore, i.e., 0.2mm to 0.4mm, and is formed to be approximately 0.16 mm. Thus, the alkaline solution L1 discharged from the alkaline solution discharge port 80a easily enters the pores, and therefore, the dirt in the pores can be washed more efficiently.

Instead of the nozzle section 40, a nozzle section 40A shown in fig. 6 may be used. In the nozzle portion 40A, a disk 45 separate from the nozzle body 41A is attached to the nozzle body 41A. Two alkaline liquid discharge ports 80a are formed in the center of the circular plate 45 in such a manner that: when the nozzle section 40A is viewed from the front (when the nozzle section 40A is viewed from the front in a state where the beauty apparatus 10 is disposed such that the nozzle section 40A is positioned above), the two alkaline liquid discharge ports 80A are arranged in the horizontal direction at a pitch of about 1.5 mm. In the nozzle unit 40A, each alkaline liquid discharge port 80A is also a hole having a diameter of about 0.16 mm.

In the nozzle portion 40A, a coupling member 42A is detachably attached to the nozzle body 41A, and a filter attachment member 46A is detachably attached to the coupling member 42A. When the filter attachment member 46A is attached to the coupling member 42A, the filter 44A is sandwiched between the coupling member 42A and the filter attachment member 46A. As described above, the filter 44A is provided in the nozzle portion 40A, whereby the alkaline solution discharge port 80A can be prevented from being clogged with foreign matter.

The skin contact portion 43 used in the nozzle portion 40A is formed in the same shape as the skin contact portion 43 used in the nozzle portion 40.

The skin contact portion 43 is formed of a material having elasticity, and is good in skin touch, and is less likely to cause irritation to the skin S even if it slides on the skin S.

The skin contact portion 43 has a peripheral wall portion 43a, and when the skin contact portion 43 is attached to the tip end (the side from which the alkaline solution L1 is discharged) of the nozzle body 41, the peripheral wall portion 43a surrounds the alkaline solution discharge port 80 a.

In embodiment 1, the peripheral wall portion 43a has an inner diameter of about 7mm and can be brought into close contact with the skin S having irregularities such as the nasal wings. Thus, when the cosmetic device 10 is used, the alkaline liquid L1 discharged to the skin S can be prevented from rebounding and scattering to the surroundings. In embodiment 1, the peripheral wall portion 43a also functions as a guide portion for guiding the alkaline solution L1 to be discharged in one direction.

A notch 43b is provided at a lower portion of the peripheral wall portion 43a, and a gap D (see fig. 7) is formed between the notch 43b and the skin S when the cosmetic device 10 is used. Thus, the alkaline liquid L1 discharged from the alkaline liquid discharge port 80a can be efficiently discharged from the gap D to the outside (lower portion) of the peripheral wall 43 a. As a result, since the alkaline liquid L1 accumulates in the lower portion of the peripheral wall portion 43a and prevents the alkaline liquid L1 from being discharged from the alkaline liquid discharge port 80a, continuous cleansing (discharge of the alkaline liquid L1 to the skin S) by the cosmetic device 10 can be suppressed. In embodiment 1, as shown in fig. 7, a direction inclined by approximately 75 ° with respect to the skin S so that the skin S side faces downward is set as the direction (one direction) in which the alkaline liquid L1 is discharged. Thus, the alkaline liquid L1 in contact with the skin S is splashed toward the gap D.

Further, by providing the skin contact portion 43 having elasticity in the nozzle body portion 41, the skin contact portion 43 can be brought into close contact with the skin S. Further, by appropriately setting the amount of projection of the peripheral wall portion 43a, the distance from the alkaline solution ejection port 80a to the skin S can be kept substantially constant (about 5mm to 7mm in embodiment 1). Thus, the cleansing force of the alkaline liquid L1 on the skin S can be kept substantially constant.

In fig. 7, the case of using the nozzle portion 40A is exemplified, but the same applies to the method of contacting the skin S with the skin contact portion 43 even when using the nozzle portion 40.

In addition to the electric motor 52 and the diaphragm pump 51 constituting the pump portion 50, a battery 60 as a power source and a circuit board (control portion) 70 for controlling electric power supplied to the electric motor 52 are provided in the hollow (cylinder) of the housing 21. The electric motor 52 and the battery 60 are supported by a bracket 71 fixed to a circuit board (control unit) 70.

Here, the beauty treatment apparatus 10 according to embodiment 1 is provided with a plurality of programs for ejecting the alkaline liquid L1 to remove dirt on the skin S of the user U.

In embodiment 1, as the plurality of programs, there are set: a first program for ejecting an alkaline solution L1 at a predetermined flow rate; and a second program for ejecting the alkaline liquid L1 at a flow rate higher than the ejection flow rate of the alkaline liquid L1 in the first program.

The first program is executed before the second program, and is set to end when a timer incorporated therein counts a predetermined time.

In embodiment 1, the first routine is intended to supply (apply) the discharged alkaline liquid L1 to the skin S. Therefore, the flow of the alkaline liquid L1 discharged in the first routine does not need to be so strong, but needs to be able to be stably supplied to the skin S. Therefore, in embodiment 1, the discharge flow rate of the alkaline liquid L1 in the first routine is set to about 6 to 7 m/s.

In consideration of the chemical reaction time of decomposition, the discharge time of the alkaline solution L1 in the first routine is preferably set to approximately 1 minute to 2 minutes. In embodiment 1, the first program is set to end after one minute has elapsed from the start of the first program.

On the other hand, the second procedure is intended to remove dirt on the skin S, that is, to wash away dirt after protein is decomposed and softened. Therefore, the flow of the alkaline liquid L1 discharged in the second routine needs to be strong. However, in embodiment 1, the softened dirt is washed away, and therefore, it is not necessary to set a strong streaming force to such an extent that the load on the skin becomes large. Therefore, the discharge flow rate of the alkaline liquid L1 in the second routine is preferably set to about 10m/s to 11 m/s.

In consideration of the load on the skin S, the discharge time of the alkaline liquid L1 in the second process is preferably 2 to 3 minutes. In embodiment 1, the second program is set to end after two minutes from the start of the second program.

In addition, the irritation to the skin felt when removing the dirt of the skin S in the second process varies from person to person. Therefore, in embodiment 1, the discharge flow rate of the alkaline liquid L1 in the second routine can be changed according to the preference of the user U. Specifically, the discharge flow rate of the alkaline liquid L1 in the second routine can be changed in three stages.

The switching of the program, the switching of the flow tendency in the second program, and the like can be performed by operating a switch provided in the casing 21. The discharge flow rate of the alkaline solution L1 and the count of the predetermined time by the timer can be controlled by the circuit board (control unit) 70.

In embodiment 1, a switch 25 for switching on/off of the power supply is formed in the housing 21 at a substantially central portion in the longitudinal direction of a position (front surface of the beauty treatment apparatus 10) on the opposite side of the recess 21 b. By pressing (operating) the switch 25, the discharge mode (the first and second programs) of the alkaline liquid L1 can be switched. The switch 25 may be of a sliding type.

In embodiment 1, when the switch 25 is pressed (operated) once in a state where the power supply is off, the power supply is switched on and the first program is selected.

When the switch 25 is pressed (operated) again in a state where the first program is selected, the ejection mode is switched from the first program to the second program. However, in embodiment 1, even if the switch 25 is pressed (operated) before the first program is ended, the first program is not switched to the second program. That is, the switch 25 is pressed (operated) after the first program is ended, thereby switching from the first program to the second program.

The first routine is set to end when the cumulative time of the discharge time of the alkaline solution L1 in the first routine is counted up to one minute. Here, the power supply is set to be turned off when the discharge of the alkaline solution L1 is not continued for a predetermined time (for example, one minute or the like) until the cumulative time reaches one minute.

When the second routine is selected, if the cumulative time of the discharge times of the alkaline solution L1 in the second routine is counted for two minutes, the second routine is terminated and the power supply is turned off. Even when the second program is selected, the power supply is turned off when the discharge of the alkaline solution L1 is not performed continuously for a predetermined time (for example, one minute or the like) until the cumulative time reaches two minutes.

Further, a selection mode display unit 26 is provided above the switch 25 of the housing 21, and by observing the selection mode display unit 26, it is possible to confirm which discharge mode is selected. The mode display unit 26 can be formed of, for example, an LED element and a light guide member.

In embodiment 1, the two mode display portions 26 are formed to be arranged in the horizontal direction. When the first program is selected, the mode display unit 26 on the left side of fig. 1A is turned on. As described above, by observing and confirming that the mode display unit 26 on the left side of fig. 1A is turned on, it can be confirmed that the first program is selected.

When the first routine is ended, the mode display unit 26 on the right side of fig. 1A blinks. As described above, by observing and confirming that the mode display portion 26 on the right side of fig. 1A is blinking, it can be confirmed that the second program can be selected. When the mode display unit 26 on the right side of fig. 1A is in a blinking state, the ejection mode can be switched from the first program to the second program by pressing (operating) the switch 25. At this time, the mode display portion 26 on the right side of fig. 1A is turned on. As described above, by observing and confirming that the mode display portion 26 on the right side of fig. 1A is turned on, it can be confirmed that the second program is selected.

The confirmation of the ejection pattern is not limited to the above-described method, and the selected pattern may be notified using, for example, characters, voice, or the like.

Further, a water pressure adjusting button 27 is provided above the mode display portion 26 of the housing 21, and when the second program is selected, the water pressure adjusting button 27 can switch the water pressure (water force) of the alkaline liquid L1 discharged from the alkaline liquid discharge port 80 a. In embodiment 1, the discharge flow rate of the alkaline liquid L1 in the second routine can be switched in three stages by pressing (operating) the water pressure adjustment button 27. The water pressure adjustment button 27 may be of a slide type.

In the state where the second program is selected, the water pressure (water force) of the alkaline liquid L1 is switched in the order of weak → medium → strong → weak each time the water pressure adjustment button 27 is pressed (operated). When the power supply of the beauty treatment apparatus 10 is turned off, the selected water pressure (water potential) is stored in the circuit board (control unit) 70. Therefore, when the power supply is turned on again, the water pressure (water potential) selected before the power supply is turned off is selected. That is, when the user U temporarily sets the water pressure (water force), the alkaline liquid L1 can be discharged at the set water pressure (water force) without pressing (operating) the water pressure adjustment button 27. By storing the selected water pressure (water potential) in the circuit board (control unit) 70 as described above, the water pressure adjustment button 27 can be kept from being pressed (operated) unless the water pressure (water potential) needs to be changed when the water pressure (water potential) is temporarily set by the user U.

A selected water pressure display unit 28 is provided above the water pressure adjustment button 27 of the housing 21, and by observing the selected water pressure display unit 28, it is possible to confirm which water pressure (water force) is selected. The selective water pressure display unit 28 may be formed of, for example, an LED element and a light guide member.

In embodiment 1, one selective water pressure display unit 28 is provided to extend in a vertically elongated manner. Then, the lighting state of the selected water pressure display unit 28 is changed according to the selected water pressure (water potential). As a method of changing the lighting state, for example, a method of changing the length, position, lighting color, and the like of a lighting portion can be given. Specifically, when the length of the lit portion is changed, for example, when "weak" is selected, the lower one-third portion of the selective water pressure display unit 28 is lit, when "medium" is selected, the lower two-thirds portion of the selective water pressure display unit 28 is lit, and when "strong" is selected, the entire selective water pressure display unit 28 is lit. When the position of the lighted portion is changed, for example, when "weak" is selected, the lower third portion of the selective water pressure display unit 28 is lighted, when "medium" is selected, the central third portion of the selective water pressure display unit 28 is lighted, and when "strong" is selected, the upper third portion of the selective water pressure display unit 28 is lighted. When the color to be lit is changed, for example, when "weak" is selected, the selective water pressure display unit 28 is lit in blue, when "medium" is selected, the selective water pressure display unit 28 is lit in green, and when "strong" is selected, the selective water pressure display unit 28 is lit in red.

As described above, by observing and confirming the length and position of the lighted portion of the selected water pressure display unit 28 and the lighting color of the selected water pressure display unit 28, it is possible to confirm which water pressure (water potential) is selected.

The method of confirming the selected water pressure (water potential) is not limited to the above method, and the selected water pressure (water potential) may be notified by, for example, characters, sound, or the like.

A cleaning button 29 for discharging the alkaline liquid L1 is provided above the selective water pressure display unit 28 of the housing 21, and the alkaline liquid L1 is discharged only when the cleaning button 29 is pressed (operated). That is, by moving the finger (hand) away from the washing button 29, the discharge of the alkaline solution L1 can be immediately stopped. This can prevent the alkaline liquid L1 from being discharged in an unexpected situation such as a state where the skin contact portion 43 is not in contact with the skin. Further, even if the cosmetic apparatus 10 is carelessly operated, the operation can be immediately stopped, and thus the cosmetic apparatus 10 can be used more safely.

The operation of the cleaning button 29 (the start and stop of the discharge of the alkaline solution L1) can also be controlled by the circuit board (control unit) 70.

Next, an example of the operation and action of the skin makeup device 10 configured as described above will be described with reference to fig. 10.

First, the user U or the like removes the container case 30 from the casing 21, adds the alkaline concentrated solution L2 for pH adjustment to the alkaline solution storage 33, and supplies a liquid L3 such as tap water to the solution, thereby producing an alkaline solution L1. In embodiment 1, an alkaline solution L1 having a pH of about 10.5 (a pH within a range of 9 to 12) is stored in the alkaline solution storage unit 33.

Then, the container case 30 storing the alkaline liquid L1 is inserted into the lower opening 21d of the housing 21, whereby the cosmetic device 10 storing the alkaline liquid L1 in the alkaline liquid storage 33 is formed.

Then, the switch 25 of the cosmetic device 10 is pressed (operated). When the switch 22 is operated as described above, the power supply is switched on, and the first program is selected.

Further, a timer (built-in timer) formed on the circuit board (control section) 70 operates.

Then, the cleansing button 29 is pressed (operated) in a state where the skin contact portion 43 of the nozzle portion 40 or the nozzle portion 40A is brought into contact with the surface of the skin S such as the nasal ala.

When the cleaning button 29 is pressed (operated) in a state where the skin contact portion 43 of the nozzle portion 40 or the nozzle portion 40A is brought into contact with the skin S as described above, the electric motor 52 is driven, and the pump portion 50 operates.

Thus, the first routine is started, and the discharged alkaline solution L1 is supplied to the skin S.

Specifically, when the pump unit 50 is operated, the alkaline liquid L1 stored in the alkaline liquid storage unit 33 flows into the membrane type pump 51 through the suction-side passage 81, and the alkaline liquid L1 flowing into the membrane type pump 51 is ejected from the alkaline liquid ejection port 80a toward the skin S such as the surface of the nasal ala of the user U through the ejection-side passage 82.

At this time, the alkaline solution L1 was discharged at a discharge flow rate of about 6 to 7 m/s. Then, the alkaline liquid L1 is supplied to the skin S, and the dirt accumulated in pores or the like is softened by the alkaline liquid L1.

The discharge time of the alkaline solution L1 in the first routine was counted by a timer, and the alkaline solution L1 was discharged until the cumulative time of the discharge times reached one minute. When the cumulative time of the ejection time reaches one minute, the circuit board (control unit) 70 ends the first routine.

After the first program is ended, when the switch 22 is pressed (operated), the ejection mode is switched from the first program to the second program.

Thereafter, by pressing (operating) the water pressure adjustment button 27, the water pressure (water force) of the alkaline solution L1 of the second routine is set to a desired intensity. Furthermore, this action is not required in case the desired intensity has been selected.

When the cleaning button 29 is pressed (operated) in a state where the skin contact portion 43 of the nozzle portion 40 or the nozzle portion 40A is brought into contact with the skin S as described above, the electric motor 52 is driven, and the pump portion 50 is operated.

Then, the second routine is started to remove dirt accumulated in pores and the like by the momentum of the jet of the discharged alkaline liquid L1.

At this time, the alkaline solution L1 was discharged at a discharge flow rate of about 10m/s to 11 m/s. As described above, by ejecting the alkaline solution L1 with a stronger momentum than in the first routine, dirt accumulated in pores or the like is removed by the momentum of the ejected alkaline solution L1.

The discharge time of the alkaline solution L1 in the second routine was also counted by a timer, and the alkaline solution L1 was discharged until the cumulative time of the discharge times reached two minutes. When the cumulative time of the ejection time reaches two minutes, the circuit board (control unit) 70 terminates the second routine and cuts off the power supply.

As described above, the cosmetic method according to embodiment 1 is a method performed using the cosmetic apparatus 10.

The cosmetic method according to embodiment 1 further includes an alkaline liquid supply step of supplying an alkaline liquid L1 to the skin S of the user U by ejecting an alkaline liquid L1 at a predetermined flow rate to the skin S of the user U by a pump unit (alkaline liquid ejecting mechanism) 50.

The beauty treatment method according to embodiment 1 includes a skin washing step of, after the alkaline liquid supply step, spraying the alkaline liquid L1 at a flow rate higher than a predetermined flow rate toward the skin S of the user U by the pump section (alkaline liquid spraying mechanism) 50 to wash the skin S of the user U (remove dirt adhering to the skin S).

In embodiment 1, the case where the discharge time of the alkaline liquid L1 in the second routine is counted by the timer is also exemplified, but the alkaline liquid L1 can be discharged until the alkaline liquid L1 in the alkaline liquid storage 33 is exhausted in the second routine. For example, the nozzle unit 40 and the nozzle unit 40A are provided with flow rate detection units, and when the discharge flow rate of the alkaline liquid L1 in the second routine is equal to or less than a predetermined flow rate, it is determined that the alkaline liquid L1 in the alkaline liquid storage unit 33 is exhausted, and the second routine is terminated.

Thus, when "weak" in which the cleaning ability is reduced as compared with the case where the flow force is "strong" or "medium" is selected, the use time can be extended, and the cleaning ability equivalent to the case where the flow force is "strong" or "medium" can be ensured.

As described above, the cosmetic device 10 according to embodiment 1 includes: an alkaline liquid storage 33 for storing alkaline liquid L1 supplied to the skin S of the user U; an alkaline liquid passage 80 having an alkaline liquid discharge port 80a through which the alkaline liquid L1 stored in the alkaline liquid storage 33 is discharged; and a pump section (alkaline liquid ejecting mechanism) 50 that can eject the alkaline liquid L1 to the skin S of the user U.

Further, a plurality of programs are set, and the programs can remove dirt on the skin S of the user U by discharging the alkaline liquid L1.

When the dirt on the skin S of the user U is removed (the skin S is cleaned) by discharging the alkaline liquid L1 as described above, the alkaline liquid L1 can promote hydrolysis of sebum, keratin, and other proteins retained in pores, and soften the dirt retained in pores. Therefore, dirt accumulated in pores and the like can be more easily removed. Further, if a plurality of programs are set as the program for removing the dirt on the skin S of the user U by discharging the alkaline liquid L1, it is possible to set a program for softening the dirt on the skin S, a program for removing the softened dirt, and the like. This enables to remove sebum, keratotic plugs, dirt such as dirt in pores more efficiently.

Further, the program may have: a first program for ejecting an alkaline solution L1 at a predetermined flow rate; and a second process of ejecting the alkaline liquid L1 at a flow rate higher than the ejection flow rate of the alkaline liquid L1 in the first process.

If the procedure for removing the dirt on the skin S of the user U by discharging the alkaline liquid L1 is made to have two procedures with different discharge rates of the alkaline liquid L1 as described above, the discharge rate of the alkaline liquid L1 can be switched in accordance with the procedures such as the supply of the alkaline liquid L1 to the skin S and the removal of the dirt on the pores by the alkaline liquid L1. As a result, the dirt such as sebum, keratotic plug, and dirt in the pores can be removed more efficiently.

Further, the first program may be performed before the second program.

In this way, after the alkaline liquid L1 is supplied to the skin S by the first process in which the discharge speed is low, the dirt such as sebum, keratotic plugs, and dirt in the pores can be removed by the alkaline liquid L1 discharged by the second process in which the discharge speed is high. As a result, the dirt such as sebum, keratotic plug, and dirt in the pores can be removed more efficiently.

Further, in order to efficiently remove the dirt in the pores, it is conceivable to further increase the ejection speed of the alkaline liquid L1 to the skin S, but in the case where the alkaline liquid L1 is ejected using only one program, the ejection speed becomes too high, which may cause irritation to the skin. On the other hand, if the first process in which the discharge speed is low is followed by the second process in which the discharge speed is high, the dirt such as sebum, keratotic plug, and dirt in the pores can be removed even if the discharge speed of the alkaline liquid L1 to the skin S in the second process is not increased more than necessary. Therefore, the irritation to the skin S can be suppressed as much as possible, and the dirt such as sebum, keratotic plugs, and dirt in the pores can be removed more efficiently.

In addition, since it is possible to suppress the time required for the first process from being consumed, the use time of the cosmetic apparatus 10 can be shortened. Further, since the amount of the alkaline liquid L1 consumed in performing the first routine can be suppressed, wasteful consumption of the alkaline liquid L1 can be suppressed. By reducing the use time as described above, the consumption of the alkaline liquid L1 can be suppressed, and the cost required for each use of the cosmetic device 10 can be reduced.

The first program may be set to end when a predetermined time is counted by a timer (built-in timer) formed on the circuit board (control unit) 70.

In this way, the end of the first program can be recognized without the user U himself/herself having to make a judgment, and therefore, the method of using the cosmetic apparatus 10 can be simplified. As a result, the usability of the cosmetic device 10 can be further improved.

In addition, if the time taken for the first process is extended to be longer than necessary, the time taken for the cosmetic device 10 to be used may be extended, and a large amount of the alkaline liquid L1 may be consumed when the first process is performed. On the other hand, if the time taken for the first process is shortened to the required time or less, the time required for the chemical reaction between the alkaline solution L1 and the scale (the time required for softening the scale) cannot be ensured, and the effect of removing the scale from the pores may be reduced.

However, if the timer is used to end the first routine, the time required for the chemical reaction between the alkaline solution L1 and the dirt can be secured without taking more time than necessary. That is, the time for the first program to be executed can be set to a more appropriate time.

This can shorten the use time of the cosmetic device 10 and further improve the pore dirt removing effect.

Further, by shortening the use time of the cosmetic device 10, the amount of the alkaline liquid L1, the electric power, and the like consumed when the first program is performed can be suppressed, and thus wasteful consumption of the alkaline liquid L1 and the electric power can be suppressed. By reducing the use time as described above, the consumption of the alkaline solution L1 and electric power is suppressed, and the cost for one-time use can be reduced.

Further, the cleaning button 26 for discharging the alkaline liquid L1 may be provided, and the alkaline liquid L1 may be discharged only when the cleaning button 26 is operated.

Thus, since the alkaline liquid L1 can be discharged at the will of the user U, the alkaline liquid L1 can be prevented from being discharged accidentally in a state where the alkaline liquid discharge port 80a is not directed toward the skin S. That is, the scattering of the alkaline liquid L1 to the surroundings when the cosmetic device 10 is used can be more reliably suppressed. As a result, the cosmetic device 10 can be used more securely, and the convenience of use of the cosmetic device 10 can be further improved.

The beauty treatment method according to embodiment 1 is a method performed using the beauty treatment apparatus 10.

The cosmetic method includes an alkaline liquid supply step of supplying an alkaline liquid L1 to the skin S of a user U by ejecting an alkaline liquid L1 at a predetermined flow rate to the skin S of the user U by a pump section (alkaline liquid ejection mechanism) 50.

The cosmetic method includes a skin cleansing step of applying an alkaline liquid to the skin S of the user U, and then cleansing the skin S of the user U by ejecting the alkaline liquid L1 at a flow rate higher than a predetermined flow rate by the pump unit (alkaline liquid ejecting mechanism) 50.

In this way, after the dirt accumulated in pores or the like is softened by the alkaline liquid L1 supplied to the skin S in the alkaline liquid supply step, the softened dirt can be removed by the alkaline liquid L1 discharged in the skin washing step (skin S washing). Therefore, the dirt such as sebum, keratotic plug, and dirt in the pores can be removed more efficiently. In addition, in the skin cleansing step, since the softened dirt is removed, the dirt can be removed even if the ejection speed of the alkaline solution L1 is not increased more than necessary. Therefore, the skin S can be prevented from being irritated as much as possible, and dirt such as sebum, keratotic plugs, and dirt in the pores can be removed more efficiently.

While the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and various modifications are possible.

For example, an energizing mechanism for energizing the skin may be provided in the cosmetic device.

Further, the cosmetic device is formed to include a stationary container housing and a cosmetic device main body provided separately from the container housing, and the alkaline liquid passage of the cosmetic device main body is communicated with the alkaline liquid reservoir portion in the stationary container housing by a tube or the like, whereby the dirt on the skin can be removed.

Further, the specifications (shape, size, layout, etc.) of the main body, the container case, and other detailed portions can also be changed as appropriate.

As described above, the cosmetic device of the present invention can remove dirt such as sebum, keratotic plugs, and dirt blocking skin pores, and thus can be applied to applications such as improving blackheads of nasal wings and cleaning scalp pores (removing dirt such as sebum, keratotic plugs, and dirt).
