Abstract
Description
- The present disclosure relates to a stain removing device and a stain removing unit, which remove stains generated by adhesion of cosmetics or food residues to a cloth product by virtue of beating and washing, and which can automatically perform an action for beating a stained portion of the cloth product and supply water to the stained portion.
- In the case where the stain is locally attached to a cloth product, in the aspects of convenience and efficiency in cleaning the stain, cleaning treatment is preferably performed only on the stained portion, as compared with cleaning of the cloth product as a whole; and a device for locally cleaning the cloth product may be, for example, a stain removing device disclosed in the
Patent Literature 1. The stain removing device is provided with a solvent ejection unit for ejecting solvent for removing the stain, and an absorption unit capable of absorbing the solvent. The stain removing device ejects the solvent towards the stained portion of clothes and the like from the solvent ejection unit and absorbs dirt and the solvent from the stained portion by the absorption unit. However, such stain removing device can remove the solvent and instantly-dissolved dirt, but has low ability for removing solid dirt which is for example massively attached onto the cloth product and difficult to be blended with the solvent, and its stain removing effect is not very good. - In addition, as a device for removing the stain, a stain removing system (Non-patent Literature 1) including a bottle containing a detergent and an absorption sheet is additionally known. In the stain removing system, the stained portion contacting with the absorption sheet can be beaten below by the top end of the bottle, and the detergent is supplied to the stained portion from pores formed in the top end by using the beating action. The detergent is impregnated into the clothes under the beating action and is absorbed into the absorption sheet together with the dirt substituting the stained portion.
- As to the stain removing system disclosed in the
non-patent literature 1, since the detergent is supplied while the beating is carried out, the massively attached solid dirt is physically decomposed to be easily dissolved in the detergent and the ability of removing the solid dirt can be improved. - Patent Literature 1:
Japanese Laid-Open Patent Publication No. 2003-996 - Non-patent Literature 1: network (URL: http://product.rakuten.co.jp/product/-/93dbf4a642737b4f28312cd6847ec47c/?sc2id=gmc_10064 7_93dbf4a642737b4f28312cd6847ec47c&scid=s_kwa_pla)
- However, in the stain removing system disclosed in the
non-patent literature 1, in the case where the solid dirt separated from the clothes by the stain removing action is not instantly dissolved in the detergent, there exist problems that the solid dirt is blocked in the pores in the top end of the bottle, the supply amount of the detergent is reduced, and the stain removing efficiency is lowered. In addition, since the stain removing action is performed by rapidly raising and lowering of a hand which holds the bottle, problems exist that the beating force and the beating speed are unstable, the decontamination degree has a deviation or the hand is fatigued. - The present disclosure aims at effectively solving the above problems. An object of the present disclosure is to provide a stain removing device and a stain removing system which can always perform the stain removing operation at stable beating force and beating speed without causing the fatigue of a hand, and can stably provide liquid required for stain removal.
- In view of the above problems, the present disclosure provides solutions as follows.
- That is, the stain removing device of the present disclosure is characterized by including a head part formed with a beating surface, a vibration unit enabling the head part to vibrate in a direction substantially orthogonal to the beating surface by power supply, a liquid containing part for containing liquid and a water supply path having one end connected with the liquid containing part and the other end opened in the periphery of the head part, wherein along with the vibration of the head part caused by the vibration unit, the liquid is provided to the periphery of the head part from the other end of the water supply path.
- Furthermore, the present disclosure is also provided with a non-flexible waterproof cover part encircling the side surface of the head part, the vibration unit comprises an elastic member capable of extending and retracting in the direction substantially orthogonal to the beating surface, the head part is protruded by an elastic force of the elastic member, and an action end on one side of the head part is set at a position which is slightly protruded from a protruding end of the waterproof cover part.
- Furthermore, the waterproof cover part of the present disclosure comprises a heater which generates heat by power supply.
- Furthermore, the present disclosure has a liquid amount adjusting portion, which allows the liquid to drip from the other end of the water supply path by using the vibration caused by the vibration unit, and which can adjust the dripping amount of the liquid.
- Furthermore, the present disclosure is also provided with a detergent containing part for holding a liquid detergent, and a detergent supply unit for supplying the detergent in the detergent containing part to the periphery of the head part.
- Furthermore, the present disclosure is provided with a steam injection unit capable of injecting steam towards the head part.
- Furthermore, the present disclosure is provided with the above stain removing device and a heating device, wherein the heating device is at least provided with a heater, which generates heat by power supply, and a heating plate having a beaten surface, to which the head part constituting the stain removing device applies an external force, and transferring the heat generated by the heater.
- According to the present disclosure described above, since the vibration unit drives the head part to vibrate by power supply, the action of the head part for beating a stain removing object can be automatically carried out. Therefore, the beating force is uniform, the hand is not required to move rapidly, and the hand is not fatigued even if the stain removing operation is performed for a long time. Furthermore, since the other end of the water supply path with one end connected with the liquid containing part is opened in the periphery of the head part rather than on the beating surface of the head part, the liquid is supplied to the periphery of the head part. Therefore, even if the solid dirt constituting the stained portion of the stain removing object is attached onto the beating surface, the water supply path is not blocked, and the stain removing effect can be stably maintained. In particular, an appropriate amount of liquid can be continuously supplied to the stain removing object along with the vibration by appropriately designing the cross section of a flow path of the water supply path, thereby improving the stain removing effect. The liquid described herein can be, for example, water, a mixture of water and detergent, a dedicated detergent for stain removal, and the like.
- In particular, according to the present disclosure having the waterproof cover part, the stain removing operation is carried out in a state that the protruding end of the waterproof cover part is pushed against the stain removing object, so that the waterproof cover part shields the liquid scattered by the vibration of the head part to prevent the liquid from being scattered in a large range; thus, a wetting area of the stain removing object can be reduced, and the stain removing object can be used immediately after the stain removing operation. Furthermore, during the stain removing operation, a distance from an device main body to the stain removing object can be always kept constant, and an external force (beating force) applied by the head part to the stain removing object can be kept moderate and uniform. Further, since the action end on one side of the head part is arranged at the position which is slightly protruded from the protruding end of the waterproof cover part, and the head part may press the stain removing object when protruding due to the elasticity of the spiral spring, the action for beating (pressing) the stained portion by the hand can be automatically simulated.
- Further, as long as the waterproof cover part comprises the heater energized to generate the heat in the present disclosure, the waterproof cover part can be heated by the heat of the heater; and the stained portion and its vicinity of the stain removing object can be always heated via the waterproof cover part during the stain removing operation, so that the stain removing effect can be further improved.
- In particular, according to the present disclosure having the liquid amount adjusting portion, which allows the liquid to drip by means of the vibration and is capable of adjusting the dripping amount of the liquid, the structure allowing the liquid to drip by means of the vibration is simpler than the structure using, for example, a liquid pump to send out the liquid. In this structure, in the case where the detergent mixture formed by mixing water and detergent is used as the liquid, the viscosity of the liquid is higher than that of the water and the liquid is difficult to drip sometimes, but the liquid can be prevented from excessively or insufficiently dripping to the stain removing object by using the liquid amount adjusting portion. Therefore, the reduction of the stain removing effect caused by the insufficient supply of the liquid can be prevented, and the circular stains caused by the supply of a great amount of liquid to the stain removing object at one time can be prevented.
- Furthermore, according to the present disclosure having the detergent containing part and the detergent supply unit, in the case where the liquid containing part only contains water, the water in the liquid containing part and the detergent in the detergent containing part can be respectively supplied to the stain removing object at different time. Therefore, the detergent supplied by the detergent supply unit can be used for removing the stains, and only the water supplied by the water supply path can be used for rinsing the stain removing object.
- In particular, according to the present disclosure having the steam injection unit, since the steam can be used for heating the stained portion of the stain removing object and for performing the stain removing operation, the dirt is in a state of being easily dissolved in the detergent, and the stain removing effect can be improved.
- In another aspect, according to the present disclosure having the above stain removing device and the heating device, since the heat from the heater can be used for continuously heating the stained portion of the stain removing object and for performing the stain removing operation, the dirt is in a state of being more easily dissolved in the detergent, and the stain removing effect can be further improved.

Figs. 1 and2 are longitudinal sectional views illustrating astain removing device 100 of the first embodiment of the present disclosure. As shown inFigs. 1 and2 , thestain removing device 100 of the present embodiment is a handheld-size device capable of locally cleaningclothes 10A as a stain removing object, and includes ahead part 1, avibration unit 2, aliquid containing part 3, awater supply path 4, abattery 5, awaterproof cover part 6 and a shellmain body 9 of a split structure with all parts assembled therein. - The head part (head of a barrel) 1 includes a beating
portion 11 having a beatingsurface 111 and a longitudinal section in a substantially semicircular shape and more specifically in a shape more approximate to a circle than the semicircle; and abarrel insertion portion 12 extending from the beatingportion 11. Thehead part 1 is made of resin (such as nylon) and vibrates in a direction substantially orthogonal to thebeating surface 111 in a state of protruding from the shellmain body 9 into a headpart containing portion 92 recessed in the shellmain body 9 via anopening 91, so as to apply a beating force to theclothes 10A used as the stain removing object and opposed to thebeating surface 111. The direction substantially orthogonal to thebeating surface 111 is referred to as a vibration direction hereinafter. In addition, in the vibration direction, a direction where thehead part 1 faces theclothes 10A is referred to as a protruding direction Y1, and an opposite direction is referred to as a returning direction Y2. Furthermore, the material of thehead part 1 is not limited to the resin and can also be metal (such as stainless used steel (SUS) and the like. - The
vibration unit 2 comprises amotor 23 which is rotated by the power supply from thebattery 5 used as an electric power supply portion, a first tothird gears 22A-22C for transferring a rotating force of themotor 23, abarrel 21 for holding thehead part 1 in a way that the beatingsurface 111 is disposed at the top end and being capable of moving in the vibration direction, and aspiral spring 24 used as an elastic component contained in thebarrel 21. - The
first gear 22A has a large-diameter portion 122a engaging with adrive gear 123 of themotor 23 and capable of rotating around a shaft 122ab, and a small-diameter portion 122b coaxially integrated with the large-diameter portion 122a. Thesecond gear 22B is disposed between thefirst gear 22A and thethird gear 22C, and has a large-diameter portion 122c engaging with the small-diameter portion 122b of thefirst gear 22A and capable of rotating around a shaft 122cd, and a small-diameter portion 122d coaxially integrated with the large-diameter portion 122c and engaging with thethird gear 22C. Thethird gear 22C is configured to rotate around a shaft 122ee (refer toFig. 1 ) in a clockwise direction in the figure, and fourbulges 22c which are formed in parallel with the shaft 122ee in the circumferential direction at equal intervals are arranged on an edge portion of the third gear. Furthermore, the number of thebulges 22c is not limited to 4 and may also be 1 to 3 and may also be 5 or more. - The
barrel 21 comprises a cylindrical closed-end spiralspring containing portion 121a containing thespiral spring 24 in a state of extending and contracting in the vibration direction, an insertedportion 121c into which thebarrel insertion portion 12 of thehead part 1 is inserted, and aliquid storage portion 121b disposed between the insertedportion 121c and the spiralspring containing portion 121a and capable of storing liquid therein. - The spiral
spring containing portion 121a is inserted by a fixedportion 93, which extends in a boss shape from the shellmain body 9 towards the protruding direction Y1, through theopening 1121 a, and contains the other end of thespiral spring 24 supported by a basic end of the fixedportion 93. Furthermore, a snap-fitting claw 1121b in snap fit with thebulge 22c of thethird gear 22C is provided on the side surface of the spiralspring containing portion 121a. With regard to thisbarrel 21, when thebulge 22c is not in snap fit with the snap-fitting claw 1121b (refer toFig. 2 ), thespiral spring 24 applies an elastic force in the protruding direction Y1 to thebottom surface 1121c of the spiralspring containing portion 121a abutted by the other end of thespiral spring 24, and thehead part 1 is pushed out. - On the other hand, in the state where the
bulge 22c is in snap fit with the snap-fitting claw 1121b (refer toFig. 1 ), thebarrel 21 applies a compressive force to thespiral spring 24 via thebottom surface 1121c along with the rotation of thethird gear 22C and moves towards the returning direction Y2. Then, when thebulge 22c is disengaged from the snap-fitting claw 1121b, the barrel moves towards the protruding direction Y1 through the elasticity of thecompressed spiral spring 24. Thehead part 1 is vibrated (vibration movement) by repeating the actions. In the present embodiment, as described above, thethird gear 22C is provided with fourbulges 22c, and thehead part 1 is reciprocated four times by one-time rotation. - The
liquid storage portion 121b comprises awide portion 1121d wider than theopening 91 of the shellmain body 9 and anarrow portion 1121e narrower than theopening 91 of the shellmain body 9 and protruding from theopening 91, wherein thewide portion 1121d is got stuck at the edge portion of theopening 91 to limit a moving range of thebarrel 21 in the protruding direction Y1. With regard to thisliquid storage portion 121b, thewide portion 1121d is connected with aliquid supply tube 41 described below, the liquid supplied from theliquid containing part 3 is stored by theliquid supply tube 41, and the liquid is supplied to the insertedportion 121c via thenarrow portion 1121e. - The inserted
portion 121c comprises awater supply hole 1121f extending from thenarrow portion 1121e, and an insertedsegment 1121g (refer toFig. 2 ) as a hole for inserting thebarrel insertion portion 12 of thehead part 1 in a relatively light pressure. A water supply groove (slot) 12a extending in the axial direction is intermittently formed on the periphery of thebarrel insertion portion 12. The liquid in thenarrow portion 1121e is supplied to the insertedsegment 1121g via thewater supply hole 1121f; in the state where thevibration unit 2 vibrates and thehead part 1 vibrates, as shown inFig. 2 , the liquid is discharged little by little in a small amount (such as 1-1.5 cc/min) from a dischargingport 1121h of thewater supply groove 12a of a specified depth (about 0.1-0.3 mm in the present embodiment) disposed in a gap between the insertedsegment 1121g and thebarrel insertion portion 12. - On the other hand, in the state where the
head part 1 does not vibrate, due to surface tension, the liquid is not discharged from the dischargingport 1121h but stored between thebarrel insertion portion 12 and the insertedportion 121c. As a result, since thewater supply groove 12a is adjusted to a size capable of discharging a small amount of liquid due to the vibration of thehead part 1, the consumption of the liquid is less than that of other cleaning ways such as a spray cleaning or a brush cleaning; and therefore, the liquid is difficult to splash to places other than the stainedportion 10a of theclothes 10A. - Furthermore, the
barrel insertion portion 12 is not limited to the structure of being inserted into the insertedportion 121c by pressure and can also be fixed and inserted by a screw. Furthermore, the insertedportion 121c is configured so that thehead part 1 can be unplugged, and other head parts can be installed on the insertedportion 121c. Therefore, in thestain removing device 100, in the case for example where the dirt is attached onto the beatingsurface 111 in direct contact with the stained portion of theclothes 10A, thehead part 1 can be removed for cleaning, or thehead part 1 itself can be replaced with a new one. Further, thewater supply groove 12a may be formed in the insertedsegment 1121g rather than in thebarrel insertion portion 12. Still further, the structure is not limited to applying the surface tension to the liquid at the dischargingport 1121h, but can also be configured to adjust thewater supply hole 1121f of thebarrel 21 to a predetermined diameter (such as 0.3 mm), so that in the state where thehead part 1 does not vibrate, the liquid is prevented from dripping by the surface tension acting on the opening end of thewater supply hole 1121f. - The
liquid containing part 3 comprises a containing portionmain body 31 for containing the liquid discharged from the insertedportion 121c and supplied to the periphery of thehead part 1, and acover component 33 for blocking aliquid supply hole 32 formed in the containing portionmain body 31. An air hole which is not shown in the figure is formed in thecover component 33. Therefore, a negative pressure is not formed inside theliquid containing part 3 even if it is closed by thecover component 33, so that the liquid can smoothly flow into thewater supply path 4, and the liquid can drip from the dischargingport 1121h immediately after the vibration is started. - Here, water, a detergent mixture formed by mixing water and detergent according to a certain ratio, dedicated detergent for stain removal and the like can be used as the liquid, and the detergent mixture is used in the present embodiment. When the detergent mixture is used as the liquid, since the detergent is continuously supplied to the
clothes 10A, the detergent cannot disappear from the stainedportion 10a due to gasification, splashing and the like during the stain removing operation, and a high stain removing effect can be maintained. Further, it is unnecessary to additionally arrange a unit for supplying the detergent, so the structure of the device becomes simple. - The
water supply path 4 supplies the liquid in theliquid containing part 3 to the periphery of thehead part 1, and comprises a flexibleliquid supply tube 41 with oneend 41a connected with theliquid containing part 3 and theother end 41b connected with thewide portion 1121d of theliquid storage portion 121b, theliquid storage portion 121b, thewater supply hole 1121f and the insertedsegment 1121g of the insertedportion 121c, and thewater supply groove 12a of thehead part 1. Here, one end of thewater supply path 4 is formed by oneend 41a of theliquid supply tube 41, and the other end of thewater supply path 4 is formed by the dischargingport 1121h formed by the opening end of thewater supply groove 12a disposed between the insertedsegment 1121g and thebarrel insertion portion 12. - The
stain removing device 100 is used in a state in which the shellmain body 9 is held in such a manner that anabsorption liner 10B used as a backing is abutted against the bottom of the stainedportion 10a of theclothes 10A, and thebeating surface 111 of thehead part 1 is opposite to the stainedportion 10a. - When a power supply switch S arranged at the outside of the shell
main body 9 is operated, themotor 23 is rotated by the power supply from thebattery 5, and the rotation is decelerated via thefirst gear 22A and thesecond gear 22B and transferred to thethird gear 22C. When thebulge 22c is in snap fit with the snap-fitting claw 1121b, thebarrel 21 and thehead part 1 are raised by a predetermined size δ (about 5 mm in the present embodiment) (refer toFig. 1 ); and when thebulge 22c is disengaged from the snap-fitting claw 1121b, thebarrel 21 is pushed out by the elasticity of thespiral spring 24, so that thehead part 1 beats the stainedportion 10a (refer toFig. 2 ). At this time, theliquid supply tube 41 absorbs the vibration of thebarrel 21 by virtue of the flexible deformation of acentral portion 41c, and the liquid slowly drips from the dischargingport 1121h along with the vibration to be supplied to the stainedportion 10a along the side surface of the beatingportion 11. - The dirt constituting the stained
portion 10a is dissolved in the liquid supplied to the stainedportion 10a and beaten from theclothes 10A by moving the shellmain body 9 along theclothes 10A and repeating such an action, and absorbed by theabsorption liner 10B. That is, thestain removing device 100 of the present embodiment removes the stains by collectively transferring the dirt of theclothes 10A and the liquid to theabsorption liner 10B. Theabsorption liner 10B is not particularly limited, and various absorption liners can be used as long as it is a component having high absorption speed of liquid. For example, a folded kitchen paper can be used as theabsorption liner 10B. Furthermore, since the dripping liquid can be stably absorbed by theabsorption liner 10B when the position where thehead part 1 is abutted against theabsorption liner 10B during the stain removing operation is periodically changed, it is possible to maintain high stain removing efficiency. Since the detergent mixture is used as the liquid in the present embodiment, even if the abutting position of thehead part 1 is changed, the detergent can also be easily and continuously supplied to the stainedportion 10a. - When the structure described above is used, since the
vibration unit 2 can vibrate thehead part 1 by supplying power, and the beating action of thehead part 1 on theclothes 10A can be automatically carried out, the beating force is uniform, the hand is not required to move rapidly, and the hand is not fatigued even if the stain removing operation is performed for a long time. Further, since the other end, i.e. the dischargingport 1121h, of thewater supply path 4 with oneend 41a connected with theliquid containing part 3 is opened in the periphery of thehead part 1 rather than on thebeating surface 111 of thehead part 1, and the liquid is supplied to the periphery of thehead part 1, even if the solid dirt constituting the stainedportion 10a is attached onto the beatingsurface 111, thewater supply path 4 does not be blocked, and the stain removing effect can be stably maintained. In particular, since an appropriate amount of liquid can be continuously supplied to the stain removing object along with the vibration by, for example, appropriately designing the cross section of a flow path of thewater supply path 4, the stain removing effect can be improved. Moreover, since the liquid is allowed to drip by vibration, the structure is simpler than that using a liquid pump to pump out the liquid. - As a result, the
stain removing device 100 in the present embodiment is small in size and good in portability; and when food residues or cosmetics are attached onto the cloth product when people are out of home, stains become unapparent after being immediately cleaned. In addition, articles which are not easy to clean as a whole, such as curtains or carpets, can be locally and properly cleaned. - As shown in
Fig. 2 , thewaterproof cover part 6 is detachably installed on the shellmain body 9 via arib 9a at a position encircling the side surface of the beatingportion 11 of the head part and is a non-flexible cylindrical transparent component made of acrylic acid in the present embodiment. Thevibration unit 2, as described above, is a component for allowing thehead part 1 to be protruded by the elastic force of thespiral spring 24; and by adjusting the travelling distance of thehead part 1, an action end on one side of thehead part 1 is arranged at a position which is slightly protruded from a protrudingend 61 of thewaterproof cover part 6. In particular, the distance t in the vibration direction from the beatingsurface 111 of thehead part 1 disposed at the protruding position to theprotruding end 61 of thewaterproof cover part 6 is a predetermined distance (about 1-2 mm in the present embodiment). - Since the
waterproof cover part 6 performs the stain removing operation in the state where the protrudingend 61 of thewaterproof cover part 6 is pushed against theclothes 10A, the liquid which is splashed due to the vibration of thehead part 1 is blocked and is prevented from being scattered in a wide range. Therefore, the wetting area of theclothes 10A can be reduced, and theclothes 10A can be put on immediately after the stain removing operation. Furthermore, during the stain removing operation, the distance from the device main body to theclothes 10A can be always kept constant, and the external force (beating force) applied by thehead part 1 to theclothes 10A is appropriate and uniform. Furthermore, since the action end on one side of thehead part 1 is arranged at the position which is slightly protruded from the protrudingend 61 of thewaterproof cover part 6, and thehead part 1 presses theclothes 10A when protruding out due to the elasticity of thespiral spring 24, the action for beating (pressing) the stained portion by hand can be automatically simulated. Further, since thewaterproof cover part 6 is transparent, the decontamination state of the stained portion can be confirmed via thewaterproof cover part 6 during the stain removing operation. - In addition, the shape of the
waterproof cover part 6 is not limited to a cylindrical shape as long as it can cover the whole side surface of the beatingportion 11, and may be, for example, a substantially conical shape (a shape that the protrudingend 61 expands towards theclothes 10A). Furthermore, thewaterproof cover part 6 may be fixed to the shellmain body 9 rather than detachably arranged on the shell main body. -
Fig. 3 is a longitudinal sectional view illustrating the state that thestain removing device 100 of the present embodiment is not in use;Fig. 3(a) is a longitudinal sectional view illustrating a liquid-drip-prevention head part 1X; andFig. 3(b) is a longitudinal sectional view illustrating ananti-leakage cover body 6X. Thestain removing device 100 of the present embodiment is configured to install the liquid-drip-prevention head part 1X shown inFig, 3(a) to the insertedportion 121c in which thehead part 1 is removed. The liquid-drip-prevention head part 1X is provided with aninsertion portion 12X, which is designed in an insertable shape and size and not formed with a gap such as thewater supply groove 12a (refer toFig. 2 ) between the insertedsegment 1121g of the insertedportion 121c. When theinsertion portion 12X is inserted into the insertedsegment 1121g, the liquid supplied via thewater supply hole 1121f is intercepted by the insertedportion 12X, so that the liquid can be prevented from dripping out of the device main body. The liquid-drip-prevention head part 1X is used when carrying thestain removing device 100, the liquid can be prevented from leaking from the device main body due to shaking or vibration, and convenience in carrying can be achieved. - Furthermore, the
stain removing device 100 of the present embodiment is configured to install theanti-leakage cover body 6X shown inFig, 3(b) on the shellmain body 9 with thewaterproof cover part 6 removed. Theanti-leakage cover body 6X comprises a cylindrical portion 6Xa with one end 6Xa1 in snap fit with therib 9a of the shellmain body 9 and a bottom 6Xb disposed at the other end 6Xa2 of the cylindrical portion 6Xa, and the liquid dripping from the dischargingport 1121h is stored in a space Sp encircled by the cylindrical portion 6Xa and the bottom 6Xb. Therefore, even if the state that thehead part 1 is inserted into the insertedportion 121c is maintained, thestain removing device 100 can be carried without leakage of the liquid. Furthermore, the shellmain body 9 may also be a structure that theanti-leakage cover body 6X is installed while thewaterproof cover part 6 is installed. -
Fig. 4 is a perspective view illustrating a portion of abarrel 155 and ahead part 151 constituting a stain removing device of a second embodiment of the present disclosure.Fig. 4(a) illustrates the state before thehead part 151 is inserted into thebarrel 155; andFig. 4(b) illustrates the state after thehead part 151 is inserted into thebarrel 155. The stain removing device of the present embodiment differs from that of the first embodiment in comprising a liquidamount adjusting portion 159 capable of adjusting the dripping amount of the liquid. In the following description, since the structure is the same as the first embodiment except for the following structure, the description thereof will be omitted. - The liquid
amount adjusting portion 159 shown inFig. 4 comprises abarrel 155 and ahead part 151. Thebarrel 155 is adjacent to aliquid storage portion 156 and an insertedsegment 1121g of an insertedportion 158 via apartition portion 157, and a first tothird supply areas 157a-157c which are formed at equal intervals are provided on the edge portion of thepartition portion 157. Different number ofsupply holes 157x penetrating through thepartition portion 157 are respectively formed in thesupply areas 157a-157c; and in the present embodiment, one supply hole is formed in thefirst supply area 157a, three supply holes are formed in thesecond supply area supply holes 157x are formed in thethird supply area 157c. Furthermore, the number of thesupply holes 157x is not limited to the above description. Furthermore, thehead part 151 is formed with anincision 1152 at the end of aninsertion portion 152, and a plurality ofwater supply grooves 1153, which extend from theincision 1152 towards the beatingportion 11, are provided at the side of theinsertion portion 152. -
Fig. 5 is a view schematically illustrating thehead part 151 and thesupply holes 157x shown inFig. 4(b) . InFig. 5 , theincision 1152 is indicated by a slash. As shown inFig. 5 , theincision 1152 is formed in theinsertion portion 152 over a range corresponding to onesupply area 157a (157b, 157c). The liquid in theliquid storage portion 156 shown inFig. 4 flows into theincision 1152 from the water supply hole(s) 157x formed in anysupply area 157a (157b, 157c) opposed to theincision 1152 and drips to the range of the beatingportion 11 through thewater supply grooves 1153. Therefore, the dripping amount of the liquid may be changed according to thesupply area 157a (157b, 157c) opposed to theincision 1152; and the dripping amount of the liquid is sequentially increased according to the state shown inFig. 5(a) where theincision 1152 is opposed to thefirst supply area 157a, according to the state shown inFig. 5(b) where theincision 1152 is opposed to thesecond supply area 157b, and according to the state shown inFig. 5(c) where theincision 1152 is opposed to thethird supply area 157. - So, the stain removing device of the present embodiment is a device allowing the liquid to drip from the other end of a
water supply path 158, i.e. gaps between thewater supply grooves 1153 and theinsertion portion 152 of thehead part 151, by virtue of the vibration of thevibration unit 2, and is provided with the liquidamount adjusting portion 159 shown inFig. 4 capable of adjusting the dripping amount of the liquid. - The liquid may excessively drip in the case of only setting the depth of the
water supply groove 12a, resulting in the formation of circular stains sometimes. However, the liquid can appropriately drip to theclothes 10A by using the liquidamount adjusting portion 159. Therefore, the reduction of the stain removing effect caused by the insufficient liquid supply can be prevented, and the circular stains caused by the supply of a great amount of liquid to the stainedportion 10a at one time can be prevented. - Furthermore, the structure of the liquid
amount adjusting portion 159 is not limited to the above structure as long as it can adjust the dripping amount of the liquid. In addition, the structure of the liquidamount adjusting portion 159 may also be applied to the stain removing devices of the following third to fifth embodiments. Further, although thewater supply grooves 1153 in the present embodiment are formed in theinsertion portion 152, they may also be formed in the insertedportion 158. -
Fig. 6 is a longitudinal sectional view illustrating astain removing device 300 of a third embodiment of the present disclosure. A shellmain body 309 of thestain removing device 300 of the present embodiment is substantially in a cuboid shape; the configuration positions of key elements embedded in the shellmain body 309 and partial structure are different from those in the first embodiment, and the shellmain body 9 in the first embodiment is used substantially in a horizontal posture, while the shellmain body 309 in the present embodiment is used substantially in a vertical posture.

Fig. 6 , thestain removing device 300 of the present embodiment is sequentially provided with abarrel 321, athird gear 322C, asecond gear 322B, afirst gear 322A and amotor 23, which constitute avibration unit 302, along the vibration direction in the shellmain body 309. Furthermore, thebarrel 321 comprises a spiralspring containing portion 321a, an inserted portion 321c and ahollow connection portion 321b connecting the spiralspring containing portion 321a and the inserted portion 321c. The structure of the spiralspring containing portion 321a is the same as that of the spiralspring containing portion 121a (refer toFigs. 1 and2 ) of the first embodiment except for an opening 1321ab formed on thebottom surface 1321a and communicated with theconnection portion 321b. Furthermore, the structure of the inserted portion 321c is the same as that of the insertedportion 121c (refer toFigs. 1 and2 ) of the first embodiment except for ahollow connection end 1321b extending from awater supply hole 1121f into theconnection portion 321b. Then, a throughhole 393a penetrating through in the vibration direction is formed in the fixedportion 393 of the shellmain body 309 inserted into the spiralspring containing portion 321 a. - A
water supply path 304 comprises aliquid supply tube 341, aconnection end 1321b of the inserted portion 321c, awater supply hole 1121f, an insertedsegment 1121g, and awater supply groove 12a arranged at thebarrel insertion portion 12 of thehead part 1. Oneend 341a of theliquid supply tube 341 is connected with theliquid containing part 3 and penetrates through the throughhole 393a of the fixedportion 393, an axial center portion of thespiral spring 24 and the spiralspring containing portion 321a, and theother end 341b is connected with theconnection end 1321b in theconnection portion 321b via the opening 1321ab. Theliquid supply tube 341 is provided with adeformation portion 341 c, and thedeformation portion 341c is connected between the liquid containingpart 3 and theconnection end 1321b with a length margin and is flexibly deformed (absorbs the vibration) along with vibration of avibration unit 302. Furthermore, theliquid supply tube 341 can also be connected with theliquid containing part 3 and theconnection end 1321b without ensuring the length margin; and at this time, in order to absorb the vibration, a part of theliquid supply tube 341 is preferably in a bellow shape. - With regard to the
stain removing device 300 of this structure, the power supply switch S at the outside of the shellmain body 309 is operated, so themotor 23 is rotated by the power supply from thebattery 5, thebarrel 321 and thehead part 1 are driven to vibrate by means of the rotation of thethird gear 22C and the elasticity of thespiral spring 24, and the liquid is enabled to drip from the dischargingport 1121h, thereby having the same effect as that of thestain removing device 100 of the first embodiment. -
Figs. 7 and8 are longitudinal sectional views illustrating astain removing device 400 of a fourth embodiment of the present disclosure. Thestain removing device 400 of the present embodiment differs from the first embodiment in that a detergent containing part 7 and adetergent supply unit 8 are provided. In the following description, since the structure is the same as the first embodiment except for the following structure, the same reference numerals in the figures are used, and the description thereof will be omitted. - The detergent containing part 7 comprises a containing portion
main body 71 containing the liquid detergent supplied to the periphery of thehead part 1, and acover component 73 which is provided with an air hole (not shown in the figures) and blocks a liquid supply hole 72 formed in the containing portionmain body 71. - The
detergent supply unit 8 is a component for supplying the detergent in the detergent containing part 7 to the periphery of thehead part 1 and comprises adetergent dripping button 81, adetergent supply tube 82 and adetergent supply portion 409a formed in a shellmain body 409 and opened around thehead part 1. Oneend 82a of thedetergent supply tube 82 is connected with the detergent containing part 7 at a position where thedetergent dripping button 81 applies a pressing force, and theother end 82b is connected with thedetergent supply portion 409a. Thedetergent supply portion 409a is formed in a shape that the detergent is supplied to the beatingportion 11 of thehead part 1 in a direction slightly inclined downwards relative to the horizontal direction, and an opening end of the detergent supply portion is in a nozzle shape. Thedetergent dripping button 81 is elastically connected with thespiral spring 81 a, which applies an elastic force from a down-pressing position to an up-pressing position. - In the present embodiment, the
liquid containing part 3 is only used for containing water, the detergent is enabled to drip on the periphery of thehead part 1 by pressing thedetergent dripping button 81 at an appropriate time; and the action of making the liftedhead part 1 as shown inFig. 7 to be protruded (as shown inFig. 8 ) is continuously performed, so that the liquid drips. Therefore, thestain removing device 400 can adjust the amount of the detergent according to the fouling degree of the stainedportion 10a. Furthermore, the water in theliquid containing part 3 and the detergent in the detergent containing part 7 are respectively supplied to theclothes 10A at different time, the detergent supplied by thedetergent supply unit 8 can be used for removing the stains, and the water supplied by thewater supply path 4 is only used for rinsing theclothes 10A. - Furthermore, the structure in which the detergent is supplied by the
detergent dripping button 81 is not limited to the above structure, and may also be, for example, the structure for supplying the detergent by vibration in the same manner as the liquid in theliquid container 3. - Furthermore, in the present embodiment, since the detergent containing part 7 and the
detergent supply unit 8 are provided to inhibit upsizing of the device main body, the structure of the third embodiment is applicable to thewater supply path 304, thebarrel 321 and the fixedportion 393 of the shellmain body 409. -
Fig. 9 is a longitudinal sectional view illustrating astain removing device 500 of a fifth embodiment of the present disclosure. Thestain removing device 500 of the present embodiment differs from that of the first embodiment in that asteam injection unit 508 capable of injecting steam to the beatingportion 11 of thehead part 1 is included and themotor 23 is powered to drive by power supply wire C with a mandrel C1. Since thestain removing device 500 is powered by the power supply wire C, no battery is required to be embedded into the shellmain body 509, and the size of the device main body is smaller. Furthermore, the power supply wire C is not limited to the structure having the mandrel C1, and may also be a structure with a USB connector and capable of USB connection. Furthermore, the First to the Fourth embodiments may also be the structure powered by the power supply wire C, and the present embodiment may also be the structure powered by the battery. In the following description, since the structure is the same as that in the first embodiment except for the following structure, the same reference numerals in the figures are used, and the description thereof will be omitted. - As shown in
Fig. 9 , thesteam injection unit 508 is provided with a steamliquid containing part 507, a steamliquid dripping button 581, asteam generation portion 583 for generating the steam, a steamliquid supply tube 582 supplying the water in the steamliquid containing part 507 to thesteam generation portion 583, and asteam injection portion 584 with oneend 584a connected with thesteam generation portion 583 and theother end 584b being opened around thehead part 1. The steamliquid dripping button 581 is elastically connected with thespiral spring 581a, which applies an elastic force from a down-pressing position to an up-pressing position. - The steam
liquid containing part 507 comprises a steam liquid containing partmain body 571 configured to contain water for steam, and acover component 573 configured to block a steamliquid supply hole 572 formed in the steam liquid containing partmain body 571 and having an air hole (not shown in the figure). Thesteam generation portion 583 comprises aheater switch 586 capable of switching the power supply state to aheater 585, theheater 585 generating heat through the power supply from the power supply wire C, a steam generation portionmain body 583 with theheater 585 arranged therein and atemperature regulator 587 arranged at the side wall of the steam generation portionmain body 583 and adjusting the power supply state to theheater 585 according to the temperature of theheater 585. Thetemperature regulator 587 is configured to stop the power supply to theheater 585 when an upper limit temperature is reached so as to cool theheater 585, and to supply power to theheater 585 again when a lower limit temperature is reached. - In the
stain removing device 500 of the present embodiment, when theheater switch 586 is operated to supply power to theheater 585 so as to generate heat, and when the liquid drips from the steamliquid containing part 507 onto theheater 585 by pressing the steamliquid dripping button 581 at an appropriate time, steam may be generated and is injected to thehead part 1 from the other end of thesteam injection portion 584. Since thestain removing device 500 is provided with thesteam injection unit 508 injecting the steam to thehead part 1, the steam can be used for heating theclothes 10A and for performing the stain removing operation, and the stain removing effect can be improved. Furthermore, since the kinetic energy of the steam is higher than that of the liquid water containing hot water, and the steam is easier to permeate into the solid dirt and theclothes 10A as compared with the liquid water, the solid dirt or the dirt deep in the fibers of the clothes can be dissolved and removed by the steam, which aids in the improvement of the stain removing effect. Further, since a powerful bleaching agent is not required for removing the stains, the color fading of theclothes 10A can be prevented. - Furthermore, in the present embodiment, since the
steam injection unit 508 is provided to inhibit upsizing of the device main body, the structure of the third embodiment is applicable to thebarrel 321 and the fixedportion 393 of the shellmain body 509. -
Fig. 10 is a longitudinal sectional view illustrating astain removing unit 600 of a sixth embodiment of the present disclosure.Fig. 11 is an exploded view illustrating aheating device 601 of thestain removing unit 600 shown inFig. 10 . Thestain removing unit 600 of the present embodiment shown inFig. 10 comprises thestain removing device 100 of the first embodiment and theheating device 601. - As shown in
Fig. 11 , theheating device 601 comprises an absorption liner setting component (absorption liner setting cover) 681, amain body cover 671, adecoration plate 661, aheating plate 651, a firstthermal insulation material 641, aheater 631, a secondthermal insulation material 621 and a devicemain body 611. - The absorption
liner setting component 681 and themain body cover 671 are, in a top view, circularly-shaped components which have openingportions liner setting component 681 is installed to themain body cover 671 by rotating in a state that theabsorption liner 10B is clamped between oneside 681b of the absorption liner setting component and oneside 671b of themain body cover 671 and by engagement of thescrew portions decoration plate 661 has step differences between acentral portion 661a and endportions 661b; in a state where the decoration plate is inserted into theheating device 601, a raised surface 661ab of thecentral portion 661a is exposed from theopening portion 671a and is substantially parallel to oneside 671b of themain body cover 671; and theend portions 661b are clamped between theother side 671d of themain body cover 671 and the devicemain body 611. Thedecoration plate 661 is made of, for example, stainless steel. Throughholes safety switch 1614 as described below are formed in theend portion 661b of thedecoration plate 661 and themain body cover 671, respectively. - The
heating plate 651 is a component which is configured to be inserted into the central portion of thedecoration plate 661, with a beatensurface 651a, which is given external force by thehead part 1 of thestain removing device 100, being opposed to thedecoration plate 661, and the heating plate is made of, for example, aluminum with high heat conductivity. The thickness of theheating plate 651 is set to about 1-2 mm. Thus, since the heating plate has both strength and high heat conductivity, the heat from theheater 631 can be rapidly and uniformly transferred to theabsorption liner 10B, the deformation of theabsorption liner 10B caused by the external force applied by thehead part 1 during the stain removing operation can be inhibited, and the high stain removing efficiency can be maintained. - The first
thermal insulation material 641 is a thermal insulation material arranged at the back side of theheating plate 651 and configured to adjust the temperature, and made of, for example, silicone rubber. The secondthermal insulation material 621 is a component arranged on the devicemain body 611 and configured to insulate the heat of theheater 631, and made of, for example, glass wool. Theheater 631 disposed between these thermal insulation materials can use, for example, a ceramic heater. Furthermore, it is also possible to use a structure in which the appearance of theheating plate 651 is beautified by implementing the coating and thedecoration plate 661 is not used. - The device
main body 611 includes apower supply wire 1613, amain switch 1611 capable of switching the power supply state to theheater 631, atemperature regulator 1612 capable of adjusting the power supply state to theheater 631 according to the temperature of theheater 631, and asafety switch 1614. When an upper limit temperature (such as 70□) is reached, thetemperature regulator 1612 stops the power supply to theheater 631 so as to cool theheater 631; and when the temperature is lowered to a lower limit temperature (such as 60□), theheater 631 is supplied power again. Thesafety switch 1614 is a component protruding from oneside 671b of themain body cover 671 via the throughholes heater 631 in the case where the safety switch is pressed by theabsorption liner 10B installed at a predetermined position and to stop the power supply to theheater 631 in the case where the safety switch is not pressed. That is, theheating device 601 can be used by arranging theabsorption liner 10B on the predetermined position of themain body cover 671 and closing the absorptionliner setting component 681. - In the
heating device 601 of this structure, when themain switch 1611 is operated, theheater 631 can generate heat, and the heat is transferred to theheating plate 651, so that the temperature of theabsorption liner 10B is increased. Therefore, when theclothes 10A are carried on theheating device 601, an action of applying beating force to the beatensurface 651a by thehead part 1 of thestain removing device 100 can be performed in a state that theheated absorption liner 10B is opposed to the stainedportion 10a. Thus, thestain removing unit 600 of the present embodiment continuously heats the stainedportion 10a to the temperature about 50□, the stain removing operation can be performed in a state that the dirt is easier to dissolve in the liquid, so that the stain removing effect can be further improved. Further, since a powerful bleaching agent is not required for removing the stains, the color fading of theclothes 10A can be prevented. - Furthermore, although the
heating device 601 is used in combination with thestain removing device 100 of the first embodiment in the present embodiment, it may be used in combination with the stain removing device 200-500 of the second to the fifth embodiments or astain removing device 700 of the seventh embodiment described below. - Furthermore, although the
heating device 601 is in a circular shape in the top view in the present embodiment, it can also be a rectangular shape in the top view. In this case, one side of the absorption liner setting component is connected with other components (the main body cover, the decoration plate, the heating plate, the first thermal insulation material, the heater, the second thermal insulation material and the device main body) of the heating device via a hinge and the like; and the absorption liner configuring component is preferably configured to clamp the absorption liner relative to other components of theheating device 601 to be foldable. -
Fig. 12 is a view illustrating astain removing device 700 of a seventh embodiment of the present disclosure. Specifically,Fig. 12(a) is a longitudinal sectional view illustrating thestain removing device 700 of the present embodiment;Fig. 12(b) is a perspective view illustrating a waterproof cover part included in thestain removing device 700 of the present embodiment; andFig. 12(c) is an exploded longitudinal sectional view illustrating the waterproof cover part. - Furthermore,
Fig. 13 is a circuit diagram schematically illustrating circuits for supplying power to amotor 23 and aheater 731 of thestain removing device 700 and illustrates three power supply statuses corresponding to siding positions of an operation portion SS1 of the switch SS. Furthermore, in the circuits ofFig. 13 , an energized portion is indicated by a solid line, while a non-energized portion is indicated by a dotted line. - As shown in
Fig. 12 , thestain removing device 700 of the present embodiment differs from that in the third embodiment shown inFig. 6 mainly in the structure of thewaterproof cover part 706 and in driving themotor 23 by power supply via a USB connector CC1. The USB connector CC1 is connected with an external power supply BB (refer toFig. 13 ) through a USB cable CC2 (refer toFig. 13 ). Thus, since thestain removing device 700 in the present embodiment is powered by the external power supply BB, no battery needs to be embedded into a shellmain body 709, and the device main body is smaller in size. In the following description, since the structure is the same as that in the third embodiment except for the following structure, the same reference numerals in the figures are used, and the description thereof will be omitted. In addition, wirings such as connecting between the USB connector CC1 and themotor 23 inFig. 12 are not shown. - As shown in
Figs. 12(a)-(c) , thewaterproof cover part 706 includes a guidingframe 732, aheater 731, apressing component 733, athermal insulation liner 734 and apower supply connector 735. Thewaterproof cover part 706 is the same as that of the above-mentioned embodiments and can be detached from the shellmain body 709 via arib 709a at a position encircling the side surface of the beatingportion 11 of thehead part 1. - The guiding
frame 732 has a flat annularbottom area 732c, an innercylindrical area 732a extending from an inner circumference of thebottom area 732c, and an outercylindrical area 732b coaxial with the innercylindrical area 732a and extending from an outer circumference of thebottom area 732c, and an inner space Is is formed by theseareas 732a-732c. Herein, as shown inFig. 12(c) , an inner surface of thebottom area 732c is configured to be bent according to the shape of theheater 731, and length L1 of the innercylindrical area 732a in the extending direction is shorter than length L2 of the outercylindrical area 732b in the extending direction. Theheater 731, thepressing component 733 and thethermal insulation liner 734 are successively arranged in the internal space Is from thebottom area 732c to anopening 732d. During the stain removing operation, anouter surface 732e of thebottom area 732c is pushed against theclothes 10A. The guidingframe 732 is made of, for example, aluminum with high heat conductivity. Therefore, since heat from theheater 731 can be rapidly transferred to theclothes 10A, and the temperature can be rapidly lowered after use, thestain removing device 700 can be stored and carried immediately after use. - The
heater 731 is an annular component formed by coiling a nickel-chromium electric heating wire and is powered by the USB connector CC1 and apower supply connector 735 to generate the heat. Furthermore, the electric power supplied to theheater 731 is, for example, about 5W; and the temperature of theheater 731 when generating the heat is set to about 80□-100□. Furthermore, theheater 731 can also be other heaters such as a ceramic heater. - The
pressing component 733 is an annular component having apressing surface 733a, the shape of which is bent according to the shape of theheater 731 with a circular longitudinal section. Thepressing component 733 restricts the movement of theheater 731 by abutting thepressing surface 733a against theheater 731 in the internal space Is, and prevent the heat of theheater 731 from being transferred to therib 709a. - The
thermal insulation liner 734 is a silicon-made annular component having a gap with the innercylindrical area 732a of the guidingframe 732 in the internal space Is and installed along the outercylindrical area 732a, and comprises acylindrical area 734a abutted against the outercylindrical area 732a and thepressing component 733 and aflange area 734b extending outwardly from the end of thecylindrical area 734a. - The
power supply connector 735 shown inFigs. 12(b) and13 protrudes from the internal space Is, is installed on an opening end surface of the guidingframe 732 and embedded with a main body side connector (not shown in the figure) arranged at the side of the shellmain body 709, and theheater 731 is electrically connected with the external power supply BB via thepower supply connector 735. - The
rib 709a is inserted into thewaterproof cover part 706 through the internal space Is, so that the insertedrib 709a is abutted against the innercircumferential surface 734c of thethermal insulation liner 734 and the waterproof cover part is installed on the shellmain body 709. At this time, the end surface of the outercylindrical area 732b of the guidingframe 732 is abutted against the shellmain body 709 via theflange area 734b of thethermal insulation liner 734, thereby thewaterproof cover part 706 is positioned in the vibration direction; and moreover, theflange area 734b plays a role in separating the shellmain body 709 from the outercylindrical area 732b. Further, as shown inFig. 12(c) , length L3 of therib 709a in the vibration direction is shorter than length L4 of thethermal insulation liner 734 in the vibration direction, and the top end of therib 709a is disposed at a position separated from thepressing component 733. Moreover, thethermal insulation liner 734 is disposed between the outercylindrical area 732b of the guidingframe 732 and therib 709a, and a thermal insulation space Gp is formed between the innercylindrical area 732a of the guidingframe 732 and therib 709a (refer toFig. 12(a) ). Further, since the length L1 of the innercylindrical area 732a is shorter than the length L2 of the outercylindrical area 732b of the guidingframe 732 as described above, in combination with the situation that the shellmain body 709 and the outercylindrical area 732b of the guidingframe 732 are separated by theflange area 734b, the top end of the innercylindrical area 732a is disposed at a position separated from the shellmain body 709. In this way, when thewaterproof cover part 706 is installed to the shellmain body 709 by using the internal space Is with theheater 731 built-in, since thepressing component 733 and the guidingframe 732, which become high temperature due to the heat of theheater 731, do not directly contact with the shellmain body 709 including therib 709a, the main body of thestain removing device 700 is prevented from being damaged by the heat from thewaterproof cover part 706. - Furthermore, in order to prevent the
guiding frame 732 and theclothes 10A from being overheated, thewaterproof cover part 706 may also be provided with a temperature regulation portion such as a temperature regulator for adjusting the power supply state to theheater 731 according to the temperature of theheater 731. In addition, thewaterproof cover part 706 may also be provided with a temperature display portion such as a thermosensitive tape for displaying the temperature of the guidingframe 732. Therefore, the temperature of thewaterproof cover part 706 can be controlled by a user. - On the other hand, although the functions of a
vibration unit 702, aliquid containing part 703 and awater supply path 704 are the same as those of thestain removing device 300 of the third embodiment, as shown inFig. 12(a) , the shape and the positions in the shellmain body 709 are different from those of thestain removing device 300 of the third embodiment. - Specifically, as shown in
Fig. 12(a) , athird gear 722C constituting thevibration unit 702 is provided with 2bulges 722c, which are protruded radially at equal intervals in the circumferential direction, instead of thebulges 22c which extend parallel to the axis 122ee (refer toFig. 6 ). The number of vibrations per unit time of thehead part 1 can be adjusted according to the number of thebulges 722c; and the beating action of thehead part 1 in the present embodiment is set to 15 to 20 times per one second. Furthermore, the number of thebulges 722c is not limited to 2 and may also be 1 or 3 or more. - Furthermore, the
barrel 721, which also constitutes the vibration unit, is configured such that a part of asecond component 721y is integrally fitted to the outer circumference of the closed-end cylindricalfirst component 721x in the vibration direction, a spiralspring containing portion 721a is arranged inside thefirst component 721x, in the part of the closed-end cylindricalsecond component 721y overlapped with thefirst component 721x and facing thehead part 1, aliquid storage portion 721b, an insertedportion 721c and an insertedsegment 1121g are arranged. Thesecond component 721y covers thefirst component 721x up to the center of the vibration direction substantially, and a snap-fitting claw 1721b that can be in snap fit with thebulge 722c of thethird gear 722C is formed at the end of thesecond component 721x on the side of thefirst component 721x. - This spiral
spring containing portion 721a contains the other end of thespiral spring 24 and a fixedportion 793 which is formed by a component different from the shellmain body 709 and which has a basic end fixed to the shellmain body 709. - The
liquid storage portion 721b comprises awide portion 1721d which is wider than anopening 1721g of the shellmain body 709 and anarrow portion 1721e which is narrower than theopening 1721g of the shellmain body 709 and which is protruded from theopening 1721g, and thewide portion 1721d is blocked by a limitingcomponent 709b which is arranged along the edge of the opening of the shellmain body 709, thereby limiting the moving range of thebarrel 721 towards the protruding direction Y1. Furthermore, the limitingcomponent 709b for the barrel is made of elastic materials such as rubber, polyurethane resin, so that the damage of thebarrel 721 and the shellmain body 709 can be inhibited; and moreover, the noise produced when thestain removing device 700 is operated can be suppressed. In addition, in order to suppress the noise when thestain removing device 700 is operated, it is also effective that the shellmain body 709 is integrally or substantially integrally designed into a double structure and the components such as thevibration unit 702 are embedded into the shellmain body 709. Furthermore, since the shell main body is of the double structure, the fixing component such as screws fixed to the inner side of the shell can be shielded by the outer side of the shell, so that the appearance designability of the stain removing device can be improved. - The inserted
portion 721c comprises a conicalwater supply hole 1721f extending from thenarrow portion 1721e and the insertedsegment 1121g, which has a width approximately the same as that of thenarrow portion 1721e and into which thecylindrical insertion portion 12 of thehead part 1 is inserted in a slightly pressing manner. - The
bottom surface 703a of the containing portionmain body 703a of the liquid containingpart 703 is inclined towards oneend 741a of theliquid supply tube 741, and the shape of the containing portionmain body 703a is different from that of the containing portion main body of thestain removing device 300 of the third embodiment. Furthermore, theother end 741b of theliquid supply tube 741 with oneend 741a connected with the liquid containing part is connected with thewide portion 1721d of thebarrel 721. Furthermore, aspiral spring 741c is wound in the vicinity of theother end 741b of theliquid supply tube 741 to prevent the immobility of the liquid caused by the bending of the flexibleliquid supply tube 741. - Furthermore, the switch SS in the present embodiment is a sliding-type switch; and the operation portion SS1 of the switch SS is provided with three sliding positions, i.e. a closed position as shown in
Figs. 12(a) and13(a) , a first sliding position as shown inFig. 13(b) and a second sliding position as shown inFig. 13(c) . Specifically, when the operation portion SS1 is in the closed position, it is a power-off state not supplying power to either of themotor 23 of thevibration unit 702 and theheater 731; and when the operation portion SS1 is in the first sliding position, it is a preheating state only supplying power to theheater 731 via thepower supply connector 735. Further, when the operation portion SS1 is in the second sliding position, it is a heating and beating state supplying power to both theheater 731 and themotor 23 of thevibration unit 702. - Therefore, in the preheated state, the
waterproof cover part 706 is pushed against theclothes 10A to heat theclothes 10A; and when theclothes 10A are heated to a certain degree, the switch SS is switched to the heating and beating state to perform the stain removing operation in a state of heating theclothes 10A. - Thus, in the
stain removing device 700 of the present embodiment, thewaterproof cover part 706 pushed against theclothes 10A is heated by the heat of theheater 731 when the stain removing operation is performed. Therefore, even if theheating device 601 shown inFig. 10 is not additionally used, the stained portion and its vicinity of the stain removing object can be always heated by thewaterproof cover part 706 in the process of stain removing operation, thereby realizing the miniaturization and further improving the stain removing effect. Furthermore, assuming that the heater is provided in the head part rather than the waterproof cover part, the heat can only be discontinuously transferred to theclothes 10A, and theclothes 10A cannot be efficiently heated. - Furthermore, in the
stain removing device 700 of the present embodiment, an LED, which is turned on when theheater 731 is in a power supply state, can also be provided. In this way, the user can control the situation where thewaterproof cover part 706 is being heated. - Furthermore, the
waterproof cover part 706 of the present embodiment can be removed from the shellmain body 709; and thewaterproof cover part 6 with no heater of thestain removing device 100 of the first embodiment shown inFig. 1 can also be installed on the shellmain body 709 of thestain removing device 700 according to the fouling condition of theclothes 10A and the available electric power. - Further, although the switch SS is of a sliding type in the present embodiment, the switch SS can also be of other types such as a knob switch or a button switch.
- In addition, the
stain removing device 700 of the present embodiment and theheating device 601 shown inFig. 10 can also be collectively used as described above, so that theclothes 10A can be more efficiently heated, and the stain removing effect can be further improved. - Although one embodiment of the present disclosure is described above, the specific structure of each portion is not limited to the above-mentioned embodiment.
