Summary of the invention

Problems to be solved by the invention

However, in the stain removing system of Non-Patent Document 1, since the hand holding the bottle body is quickly subjected to the stain removing operation up and down, there is a problem that the striking force and the knocking speed are unstable, the degree of decontamination is deviated, or the hand is fatigued. Further, since the detergent in the bottle body cannot be replaced, and the detergent can not be used depending on the type and state of the stain such as oil stain or water-based stain, it is sometimes difficult to remove the stain.

The object of the present invention is to effectively solve such a problem, and an object of the invention is to provide a stain removing device and a stain removing system, which can prevent the hand from being fatigued, and always have a stable tapping force and a tapping speed. The stain removal operation can also use different types of detergents and the like depending on the type and state of the stain.

Method for solving the problem

The present invention has been conceived in view of the above problems.

In other words, the stain removing device of the present invention includes a cassette mechanism having a head portion on which a knocking surface is formed, a liquid accommodating portion for accommodating a liquid, and the liquid accommodating portion extending over the head portion. a water supply path formed by the ground; and a device main body having a vibration unit that detachably houses the cassette mechanism and vibrates the cassette mechanism in a direction substantially orthogonal to a striking surface of the head by power supply, accompanied by The vibration of the cassette mechanism caused by the vibration unit supplies the liquid from the liquid accommodating portion to the striking surface of the head via the water supply path.

Further, in the invention, it is preferable that the head portion is detachable from the cassette mechanism, and the liquid accommodating portion is constituted by a accommodating portion main body having a liquid accommodating space formed therein and a lid member that opens and closes the liquid accommodating space.

Further, in the invention, it is preferable that the liquid containing portion is transparent or translucent.

Further, in the invention, it is preferable that the water supply passage is configured to extend from the liquid accommodating portion through the head portion to the striking surface and to expand toward an opening end of the knocking surface.

Further, in the invention, it is preferable that the apparatus main body further includes an inflexible waterproof cover portion surrounding a side surface of the head portion, wherein the vibration unit has an elastic member that can expand and contract in a direction substantially orthogonal to the striking surface, and the elastic member passes through the elastic member. The elastic force of the elastic member causes the head to protrude, and the action end on the side of the head is set at a position slightly protruding from the protruding end of the waterproof cover portion.

Further, the stain removing unit of the present invention includes the above-described stain removing device and a heating device including at least a heater that generates heat by power supply and a head portion that is formed by the stain removing device. A heating plate of an external force that is knocked on the surface and transfers heat generated by the heater.

Effect of the invention

As described above, according to the present invention, since the vibrating unit vibrates the cassette mechanism in a direction substantially orthogonal to the striking surface by the power supply, the head can automatically perform the action of tapping the stain removing object, so that the striking force and the striking speed are uniform and There is no need to move the hand quickly, and the hand will not be fatigued even if the stain removal operation is performed for a long time. Further, since the cassette mechanism can be detached from the apparatus main body, for example, a plurality of cassette mechanisms each housing a different type of liquid are prepared in advance in the liquid accommodating portion. The cartridge mechanism in which the liquid corresponding to the state of the stain portion is housed is attached to the main body, and the type of the liquid can be changed according to the state of the stain portion, and the stain removing effect can be improved.

In particular, according to the present invention in which the head portion is detachable from the cassette mechanism and the liquid accommodating portion is constituted by the accommodating portion main body and the cover member, the liquid can be replenished by removing the cover member from the accommodating portion main body. The liquid accommodating space or the liquid in the accommodating portion can be easily replaced with another type of liquid, so that the stain removing device can be repeatedly used many times. In this case, since the liquid can be replenished, replaced, or the like in a state where the liquid accommodating portion is removed from the apparatus main body, the apparatus main body is not wetted by the liquid during replenishment, and it is not necessary to waterproof the apparatus main body. . In addition, the accommodating portion main body and the lid member can be detached to clean the inside of the liquid accommodating portion, and scale, calcium component, and the like can be easily removed. Further, since the most suitable head and liquid can be selected depending on the state of the stain portion, the stain removing effect can be further improved.

Further, according to the present invention, the liquid accommodating portion is transparent or translucent, and the cartridge mechanism can be temporarily taken out during the process of the stain removing operation or the like, and the liquid remaining amount in the liquid accommodating portion can be confirmed, thereby improving convenience.

In particular, according to the present invention in which the open end of the water supply path is expanded, even if the solid dirt constituting the stain portion is physically decomposed due to the impact from the head, it does not dissolve in the liquid and penetrates into the water supply path, since the open end is expanded. Therefore, the water supply path is also difficult to be blocked by solid dirt, and can be easily removed even if it is filled with solid dirt.

In addition, according to the present invention having the waterproof cover portion, the waterproof cover portion can block the scattering of the liquid to prevent the liquid from diffusing over a wide range, and the distance between the main body and the laundry is always fixed in the stain removing operation, and the head is applied to the stain. The external force (knocking force) for removing the object is suitable and uniform. Further, since the head is pressed against the stain removing object by the elasticity of the elastic member when protruding, the action of tapping (pressing) the stain portion by hand can be automatically simulated.

On the other hand, according to the present invention having the above-described stain removing device and heating device, since the stain portion of the object can be removed by heat from the heater to remove the stain portion of the object and the stain removing operation is performed, the stain is more soluble in the liquid. The state can further improve the stain removal effect.

FIG. 1(c) is a plan view showing the stain removing device 100. 2(a) is a longitudinal cross-sectional view showing the stain removing device 100 shown in FIG. 1(c) taken along the line II-II. Fig. 2(b) is a perspective view showing a part of the stain removing device 100, specifically showing the vicinity of the engaging claw 45b2. Fig. 2 (c) is a longitudinal cross-sectional view showing a part of the head portion 11 and the liquid accommodating portion 12 shown in Fig. 2 (a) in an enlarged manner. 2(d) is a bottom view of the head 11.

As shown in FIG. 2( a ), the stain removing device 100 includes an apparatus main body 3 , a cassette mechanism 1 , a cover member 70 , and a waterproof cover portion 50 .

The apparatus main body 3 detachably houses the cassette mechanism 1, and has a vibration unit 31, a battery 32, and a case main body 33 of a split structure in which these components are mounted.

The vibration unit 31 is a member that vibrates in a direction substantially perpendicular to the striking surface 21a of the head portion 11 by the cassette mechanism 1 protruding from the case main body 33 via the opening 33a by electric power supply. Hereinafter, a direction substantially orthogonal to the striking surface 21a is referred to as a vibration direction. Further, in the vibration direction, a direction in which the head portion 11 protrudes outward is referred to as a protruding direction Y1, and an opposite direction is referred to as a returning direction Y2. Such a vibration unit 31 has a motor 41, first to third gears 42 to 44, a cylinder 45, and a coil spring 46.

The motor 41 includes a drive gear 41a that rotates by power supply from the battery 32 that is a power supply unit.

The first to third gears 42 to 44 transmit the rotational force of the motor 41. The first gear 42 has a large diameter portion 42a that meshes with the drive gear 41a of the motor 41 and is rotatable around the shaft 42c, and a small diameter portion 42b that is integrally formed coaxially with the large diameter portion 42a. The second gear 43 is disposed between the first gear 42 and the third gear 44, has a large diameter portion 43a that meshes with the small diameter portion 42b of the first gear 42 and is rotatable about the shaft 43c, and is coaxial with the large diameter portion 43a. The manner is formed as a single body and a small diameter portion 43b that meshes with the third gear 44. The third gear 44 has a large diameter portion 44a that meshes with the small diameter portion 43b of the second gear 43 and is rotatable around the shaft 44c, and is integrally formed coaxially with the large diameter portion 44a and has a circumferential direction from the end surface thereof. The small diameter portions 44b of the two engaging projections 44b1 projecting at equal intervals. Further, the number of the engagement projections 44b1 is not limited to two, and may be one or three or more.

The cylindrical body 45 is a member that supports the cassette mechanism 1 so as to be movable toward the vibration direction so that the knocking surface 21a is positioned at the distal end, and has a coil spring housing portion 45a and a cassette mechanism insertion portion 45b.

The coil spring accommodating portion 45a is a bottomed tubular member that accommodates a coil spring 46 as an elastic member in a state in which it can expand and contract in the vibration direction.

The cassette-type mechanism insertion portion 45b is a substantially cylindrical member that extends from the lower end portion of the coil spring housing portion 45a to the vicinity of the opening 33a of the case body 33. A cylindrical opening 45b' shown in Fig. 2(b) is formed on a side surface of the cartridge mechanism inserted portion 45b, and is provided to be engageable with the engaging projection 44b1 formed at the small diameter portion 44b of the third gear 44. The engaged claw 45b1 shown in Fig. 2(a) and the engaging claw 45b2 of the cartridge type mechanism 1 can be engaged. As shown in Fig. 2(b), the engaging claw 45b2 extends from the edge portion of the cylindrical opening 45b' toward the protruding direction Y1, and the distal end portion 45b3 is substantially triangular in longitudinal section toward the central axis of the cartridge mechanism inserted portion 45b. Prominent. Further, the engagement claw 45b2 is configured to be elastically deformed toward the outside of the cartridge mechanism insertion portion 45b with the base end 45b4 as a starting point by the pressing from the cassette mechanism 1. Such engaging claws 45b2 are disposed at two positions at positions facing each other.

One end side of the coil spring 46 is supported by the proximal end side of the fixing portion 33b extending in a boss shape from the case main body 33 in the protruding direction Y1, and the other end side is housed by the coil spring housing portion 45a.

As shown in Fig. 2(a), the cylindrical body 45 is in a state where the engaging projection 44b1 of the third gear 44 is not engaged with the engaged claw 45b1, because the coil spring 46 faces the bottom surface of the coil spring housing portion 45a. Since the 45a1 imparts an elastic force to the protruding direction Y1, it is pushed out together with the cassette mechanism 1 in the protruding direction Y1.

On the other hand, in a state in which the engaging projection 44b1 of the third gear 44 is engaged with the engaged claw 45b1 (see FIG. 4(b)), the cylindrical body 45 is rotated by the bottom surface 45a1 along with the rotation of the third gear 44. The coil spring 46 applies a compressive force and moves in the return direction Y2 together with the cassette mechanism 1. Then, when the engaging projection 44b1 When disengaged from the engaged claw 45b1, the tubular body 45 and the cassette mechanism 1 are again moved in the protruding direction Y1 by the elasticity of the compressed coil spring 46.

By repeating such an action, the cassette mechanism 1 or the head portion 11 is vibrated (amplitude movement). In the present embodiment, as described above, the third gear 44 has two engagement projections 44b1, and the head portion 11 is reciprocated twice by one rotation.

In the present embodiment, the battery 32 shown in FIG. 2( a ) is a dry battery, and is housed in the apparatus main body 3 via an opening and closing cover 34 formed at a part of the case main body 33 . The opening and closing cover 34 is configured to be rotatable toward the outside of the case main body 33 via the pin 34a.

The cassette mechanism 1 vibrated by the vibration unit 31 has a head portion 11, a liquid accommodating portion 12, and a water supply path 13.

The head portion 11 has a striking portion 21 and a head insertion portion 22. The striking portion 21 is a substantially semicircular longitudinal section in which the striking surface 21a is formed, and more specifically, a member that is slightly rounded compared to the semicircle, and the plurality of projections 21a1 protrude from the striking surface 21a. Each of the projections 21a1 has a hemispherical shape and is regularly disposed in the striking surface 21a as shown in Fig. 2(d).

As shown in FIG. 2(c), the head insertion portion 22 is a member that extends from the striking portion 21 and is detachably inserted into the inserted portion 25 to be described later. The side surface of the head insertion portion 22 has mutual vibration directions. A plurality of annular projections 22a are formed separately. When inserted into the inserted portion 25, the protruding portion 22a presses the inner surface of the inserted portion 25, and even if the attachment and detachment are repeated a plurality of times, the head portion 11 can be stably fixed with a constant degree.

Further, in the present embodiment, the head portion 11 is made of a resin (for example, nylon), but the material is not limited to a resin, and may be a metal (for example, stainless steel (Stainless Used Steel: sus)).

The liquid storage unit 12 shown in FIG. 2( a ) has a liquid storage unit 24 and an inserted portion 25 . The liquid storage portion 24 is a transparent or translucent hollow core member capable of accommodating a liquid, and is configured to be decomposed as will be described later. An engagement recess 12a that can be engaged with the engagement claw 45b2 is provided on a side surface of the liquid storage portion 24. The inserted portion 25 extends from the liquid storage portion 24, and the head insertion portion 22 of the head portion 11 is detachably inserted therein by gentle pressing. Further, the head insertion portion 22 is not limited to the configuration in which the inserted portion 25 is inserted by press fitting, and may be inserted and fixed by screws.

Here, as the liquid, water, a detergent mixture in which water and a detergent are mixed in a predetermined ratio, a common solvent such as ethanol or gasoline, or a special detergent for removing stains can be used. In the present embodiment, since only water is used as the liquid contained in the liquid storage portion 24, as described later, in addition to the stains In addition to the removal effect, the rinsing effect can also be exerted.

The water supply path 13 is formed from the liquid accommodating portion 12 over the head portion 11, and the liquid in the liquid accommodating portion 12 is supplied to the striking surface 21a of the head portion 11, and has a head water supply hole as shown in Fig. 2(c). 27 and the cylinder water supply hole 28. The head water supply hole 27 extends through the head portion 11 to the striking surface 21a, and is composed of a water storage portion 27a, an expanded portion 27b, and a small diameter portion 27c.

The water storage portion 27a faces the tubular water supply hole 28 and is opened at the base end 11a of the head portion 11, and penetrates the head insertion portion 22 in a substantially rectangular shape in a longitudinal section. The expanded portion 27b has a longitudinally-shaped boss shape and has an open end 11b that is expanded toward the center of the knocking surface 21a and opened. The small diameter portion 27c is configured to connect the water storage portion 27a and the expansion portion 27b, and the flow path cross section is smaller than the water storage portion 27a and the expansion portion 27b.

The cylindrical water supply hole 28 is formed through the insertion portion 25 from the liquid storage portion 24, and is tapered toward the base end 11a of the head portion 11. Further, the longitudinal section of the cylinder water supply hole 28 is not limited to a taper, and may be set to have the same diameter from the beginning to the end. The same is true in other embodiments to be described later.

The liquid in the liquid storage portion 24 is dropped from the cylindrical water supply hole 28 to the head portion 11, and then supplied to the striking surface 21a through the head water supply hole 27.

The water supply path 13 formed in the head portion 11 is a small amount of liquid (for example, 1 to 1.5 cc/min) from the small diameter portion 27c at a steady flow rate in a state where the vibration unit 31 vibrates to vibrate the cassette mechanism 1. It is discharged to the expanded portion 27b, and liquid is supplied to the striking face 21a of the head portion 11. On the other hand, in a state where the cassette mechanism 1 is not vibrated, the liquid droplets are prevented from falling by the surface tension in the small diameter portion 27c and the cylindrical water supply hole 28 (particularly, the small diameter portion 27c).

In this way, since the flow path cross section of the water supply path 13 is designed to discharge a small amount of liquid by the vibration of the head 11, compared with other cleaning methods such as spray cleaning, brushing, etc., the amount of liquid used is less cleaned, so the liquid It is difficult to fly to a place where no liquid is required. In addition, since the water supply path 13 is disposed only in a part that is limited with respect to the entire stain removing apparatus 100, the water supply path 13 is configured to be longer than the water supply path 13 so as to extend over the entire stain removing apparatus 100 (not shown). The clogging of the water supply path 13 due to the solidification of the scale and the calcium component is less likely to occur, and the cumbersome disassembly cleaning of the stain removing device 100 is not required.

Further, the length β of the stain removing device 100 from the striking surface 21a of the head portion 11 to the opening 33a of the case main body 33 (see FIG. 2(a)) is set so that the stain portion can be removed in the stain removing operation to be described later. The length that is not visually obscured by the apparatus main body 3 from obliquely above. Further, the waterproof cover portion 50 to be described later is set to a size corresponding to the length β. Further, the cassette mechanism 1 is mounted to be opposed to the cylindrical case main body 33. In the eccentricity, the stain removing operation can be performed more easily by bringing the side of the case main body 33 located closest to the cassette mechanism 1 closer to the front of the eye, thereby making it possible to more easily confirm the stain portion.

The cover member 70 is a member detachably attachable from the end of the case main body 33, and is attached to the apparatus main body 3 when carrying the stain removing device 100, and is subjected to a stain removing operation to be described later, as shown in Fig. 3(a). It is removed from the apparatus main body 3. Fig. 3 (a) is a perspective view showing the stain removing device 100 in a state where the cover member 70 is removed. With such a cover member 70, it is possible to effectively prevent water leakage to the outside of the device during carrying, impact on the cassette mechanism 1, and the like.

3(b) is a perspective view showing the stain removing device 100 in a state where the waterproof cover portion 50 is removed, and the waterproof cover portion 50 is also configured from the end of the case main body 33 as shown in FIG. 3(b). Department loading and unloading. Further, the relevant structure of the waterproof cover portion 50 will be described in detail later.

Such a stain removing device 100 is a device that can partially clean the hand-held size of the laundry C as the stain removing object shown in FIG. FIG. 4 is a longitudinal cross-sectional view for explaining a state of use of the stain removing device 100. At the time of the stain removing operation, the absorbent pad P abuts against the underside of the stain portion Sp of the laundry C as a spacer, and directly applies the stain removing detergent to the stain portion Sp of the laundry C. Moreover, the protruding end 51 of the waterproof cover portion 50 presses the laundry C at a position where the striking surface 21a of the head portion 11 opposes the stain portion Sp, and is held by the annular anti-slip portion 33d of the case main body 33. The stain removing device 100 is used below. Further, in the present embodiment, it is also possible not to use a detergent.

When the power switch Sw provided outside the case main body 33 is operated in this state, the motor 41 is rotated by the power supply from the battery 32, and the rotation is decelerated via the first gear 42 and the second gear 43 and transmitted to the third gear 44. When the engaging projection 44b1 is engaged with the engaged claw 45b1, as shown in FIG. 4(b), the tubular body 45 and the cassette mechanism 1 are lifted together by a predetermined size δ (about 5 mm in the present embodiment). Then, when the engaging projection 44b1 is disengaged from the engaged claw 45b1, the cylindrical body 45 and the cassette mechanism 1 are pushed out by the elasticity of the coil spring 46, as shown in Fig. 4(a), the head 11 is struck in the stained portion. Sp.

Further, since the liquid and the air are stirred in the liquid storage portion 24 accompanying the vibration of the cassette mechanism 1, the negative pressure is not formed in the liquid storage portion 24, and the liquid slowly drops through the water supply path 13 immediately after the start of the vibration. The falling surface is supplied from the striking face 21a to the stain portion Sp.

When the apparatus main body 3 is moved along the laundry C and the operation is repeated, the liquid supplied to the stain portion Sp (only water is used in the present embodiment) is dissolved together with the detergent applied to the stain portion Sp. The stain portion Sp is dirty and is knocked out from the laundry C and absorbed by the absorbent pad P. That is, the stain removing device 100 transfers the dirt of the laundry C together with the liquid and the detergent to A device that absorbs the pad P to remove stains.

Further, in the present embodiment, it is also effective to continue the above-described operation for a certain period of time after the stain is removed, whereby the detergent remaining in the stain portion Sp is transferred to the absorbent pad P, and the rinsing effect can be exhibited.

Further, the absorbent pad P is not particularly limited as long as the liquid is absorbed at a high speed, and various articles can be used. For example, a product obtained by folding a kitchen towel can be used.

Further, since the operation of changing the position at which the head portion 11 abuts on the absorbent pad P is periodically performed in the stain removing operation, the dripped liquid is stably absorbed by the absorbent pad P, thereby maintaining high stain removal efficiency. status.

In the stain removing apparatus 100 having the above configuration, since the vibrating unit 31 vibrates the cassette mechanism 1 in a direction substantially orthogonal to the striking surface 21a by the power supply, the head portion 11 can automatically perform the action of tapping the laundry C, thereby having a tapping force and a uniform tapping speed. Moreover, it is not necessary to move the hand quickly, and the hand does not fatigue even if the stain removal operation is performed for a long time.

Further, although the stain is, for example, a solid stain that is hard to be fused with the liquid, which is attached to the laundry C in a block shape, the stain removing device 100 can physically decompose the solid dirt by the impact from the head 11 to be easily dissolved in the liquid. . Further, for example, by appropriately designing the flow path cross section of the water supply path 13, an appropriate amount of liquid is continuously supplied to the laundry C with vibration, and the stain removing effect can be improved. Further, since the stain removing device 100 is a structure in which the liquid is dripped by the vibration, the structure can be simplified and the size can be reduced as compared with, for example, a device that uses a liquid pump to send out the liquid.

As a result, the stain removing device 100 of the present embodiment is a small-sized and portable device. When the food residue, the ornament, or the like is attached to the cloth product, the stain can be made inconspicuous by using the partial cleaning. In addition, articles such as curtains and carpets that are not easily cleaned as a whole can be appropriately cleaned locally. Further, it is also applicable to the pre-cleaning of the stain on the collar, the cuff, and the like of the garment C by the stain removing device 100 in the early stage of washing by the washing machine.

Further, as described above, the water supply path 13 extends from the liquid accommodating portion 12 through the head portion 11 to the striking surface 21a, and expands toward the opening end 11b (see FIG. 2(c)) that is opened to the striking surface 21a. Therefore, even if the solid dirt constituting the stain portion Sp is insoluble in the liquid into the water supply path 13 after being physically decomposed by the impact from the head 11, the water supply path 13 is hardly blocked by the solid dirt due to the expansion of the open end 11b. In addition, it can be easily removed even if it is filled with solid dirt.

As shown in FIG. 4, the waterproof cover portion 50 is made of acryl and is inflexible and has a substantially conical shape (protruding A transparent member having a shape in which the circumference of the end 51 is larger than the circumference of the base end 51' is detachably attached to the vicinity of the opening 33a of the case main body 33 via the rib 33a1 at a position surrounding the side surface of the head portion 11. The head portion 11 that protrudes in the protruding direction Y1 by the vibration unit 31 adjusts its stroke, and the one side operation end is set at a position that can slightly protrude from the protruding end 51 of the waterproof cover portion 50. Specifically, specifically, the distance t (see FIG. 4(a)) in the vibration direction from the striking surface 21a of the head portion 11 located at the protruding position to the protruding end 51 of the waterproof cover portion 50 is set. The distance (in the present embodiment, it is about 1 to 2 mm).

By providing such a waterproof cover portion 50, the waterproof cover portion 50 blocks the scattered liquid by the vibration of the head portion 11 during the stain removing operation, thereby preventing the liquid from diffusing in a wide range, thereby reducing the area in which the laundry C is wetted. Put on clothing C immediately after the stain removal operation. In addition, during the stain removing operation, the distance from the apparatus main body 3 to the laundry C can be kept constant at all times, and the external force (knocking force) of the head portion 11 can be imparted to the garment C appropriately and uniformly. In addition, since one side of the operating end of the head portion 11 is set at a position slightly protruded from the protruding end 51 of the waterproof cover portion 50, and the head portion 11 presses the laundry C when the elasticity of the coil spring 46 is protruded, it can be automatically realized. A simulated motion of an action of tapping (pressing) the stain portion Sp by hand. Further, since the waterproof cover portion 50 is transparent, the stain-removed state of the stain portion can be confirmed via the waterproof cover portion 50 during the stain removing operation.

Further, the shape of the waterproof cover portion 50 is not limited to a substantially conical shape, and may be, for example, a cylindrical shape.

As shown in Fig. 6(a), the liquid storage portion 24 of the cassette mechanism 1 is configured to be decomposed by the housing portion main body 24a and the lid member 24b. The accommodating portion main body 24a is a bottomed substantially cylindrical member in which the liquid accommodating space S is formed, and is configured such that a part of the axial direction is reduced in the radial direction, thereby forming the engaging recessed portion 12a. The lid member 24b is a member that is provided on the opening side of the accommodating portion main body 24a and is attached to the accommodating portion main body 24a by screwing, and opens and closes the liquid accommodating space S. Further, the head portion 11 is configured to be detachable from the inserted portion 25, that is, detachable from the cassette mechanism 1.

With such a structure which can be divided into three parts, the cover member 24b can be removed from the accommodating portion main body 24a, the liquid can be replenished into the liquid accommodating space S, or the liquid in the liquid accommodating portion 12 can be easily replaced with another type of liquid. (For example, a common solvent such as ethanol or gasoline), the stain removing device 100 can be repeatedly used. At this time, since the liquid accommodating portion 12 can be replenished and replaced in a state of being detached from the apparatus main body 3, the apparatus main body 3 is not wetted by the liquid at the time of replenishment, and it is not necessary to implement the apparatus main body 3. Waterproof treatment. In addition, it can be decomposed into the accommodating portion main body 24a and the lid member 24b to clean the inside of the liquid accommodating portion 12, and the scale, the calcium component, and the like can be easily removed. Further, the head portion 11 and the liquid of the optimum shape can be selected for use according to the state of the stain portion Sp or the like, and the head portion 11 itself can be replaced with a new one, which can improve the stain removing effect.

Further, since the liquid accommodating portion 12 is transparent or translucent as described above, the cartridge mechanism 1 can be temporarily taken out in the middle of the stain removing operation, and the remaining amount of the liquid in the liquid accommodating portion 12 can be confirmed, thereby facilitating the convenience. Sex.
