Description

Technical Field

[0001] The present invention relates to a hair washing device and a hair washing system.

Background Art

[0002] As a method of washing the body when it is difficult to take a bath in an outdoor environment or during illness convalescence, methods such as enclosing to prevent water from splashing around, or using a shower or pouring hot water with a tray attached to receive the water after bathing are carried out. In the method of using a normal shower or pouring hot water, a large amount of water (hot water) is used, so it is necessary to treat a large amount of drainage. Even when using a tray or the like, it is inevitable that a large amount of water droplets scatter around. Also, it is difficult to wash hair alone without a caregiver.

[0003] Conventionally, even when it is difficult to take a bath in an outdoor environment, convalescence in a hospital room, etc., a shower device has been known that is devised so that the body can be washed without splashing water around. For example, the shower device of Patent Document 1 has a waterproof wall on the outer periphery of the shower head, and a clean water discharge port and a drainage suction port are provided inside the waterproof wall. By performing washing with this shower head in close contact with the body washing part, the shower device sucks the washed dirty water together with the washing.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in Patent Document 1, the purified water discharge port and the drainage suction port are fixedly installed inside the waterproof wall. Therefore, when the shower head is separated from the body, the shower device cannot suck the washed sewage. Accordingly, although the sewage can be sucked when washing the surface of the body, for example, the sewage cannot be sucked when washing the hair. That is, it is difficult to wash the hair without splashing water. In particular, it is difficult to wash the part of the hair away from the scalp, and when the hair is long, the hair cannot be washed sufficiently.

[0006] In view of the above situation, an object of the present invention is to provide a hair washing device that can easily wash a part of the hair away from the scalp without splashing water.

Means for Solving the Problems

[0007] In order to achieve the above object, a hair washing device according to one aspect of the present invention includes a blowing unit and a suction unit. The blowing unit blows a blown body in which a liquid-phase fluid is atomized or vaporized forward from a nozzle. The suction unit is detachable from the blowing unit and can suck the blown body. The gripping portion is gripped by a user.

[0008] Further, in order to achieve the above object, a hair washing system according to one aspect of the present invention includes the above-described hair washing device, a supply device, and a suction device. The supply device supplies the blown body or the fluid to the blowing unit. The suction device sucks the blown body from the suction unit.

[0009] Further features and advantages of the present invention will be further clarified by the embodiments shown below.

Effects of the Invention

[0010] According to the present invention, it is possible to provide a hair washing device that can easily wash a part of the hair away from the scalp without splashing water.

Mode for Carrying Out the Invention

[0012] Embodiments of the present invention will be described below with reference to the drawings.

[0013] <1. Hair washing system 100> FIG. 1 is an external view showing a configuration example of a hair washing system 100. FIG. 2 is a block diagram showing a configuration example of a control system of the hair washing system 100. FIG. 3A is a schematic diagram showing an application example of the hair washing system 100. FIG. 3B is a schematic diagram showing another application example of the hair washing system 100.

[0014] <1-1. Hair washing device 101, supply device 200, suction device 300> The hair washing system 100 is, for example, a shower system for bathing an object to be blown M in an outdoor environment, indoors, etc. Note that the object to be blown M includes at least one of droplets and vapor obtained by atomizing or vaporizing a liquid-phase fluid F. In the present embodiment, the fluid F is water, and the object to be blown M is fine water droplets that are dispersed and floating.

[0015] As shown in FIG. 1, the hair washing system 100 includes a hair washing device 101, a supply device 200, and a suction device 300.

[0016] The hair washing device 101 is a shower head device for the user U to be exposed to the object to be blown M. The hair washing device 101 blows out the object to be blown M from the blowing part 1 and sucks at least a part of the object to be blown M by the suction part 2. In the present embodiment, the fluid F is a liquid, and the object to be blown M is fine droplets (i.e., mist) that are dispersed and floating. However, it is not limited to this example, and both the fluid F and the object to be blown M may be gases.

[0017] The supply device 200 is connected to the blowing part 1 of the hair washing device 101 via the supply hose Hs. The supply device 200 supplies the object to be blown M or the fluid F to the blowing part 1. The supply device 200 includes a supply tank 201 and a supply pump 202. The supply tank 201 stores the fluid F to be supplied to the blowing part 1. The supply pump 202 supplies the fluid F from the supply tank 201 to the blowing part 1 via the supply hose Hs. In the present embodiment, the fluid F is supplied to the blowing part 1 via the supply hose Hs, is made into a mist state at the blowing part 1, and is blown out to the outside of the blowing part 1. Note that the supply device 200 may be a municipal water pipe. For example, municipal water can be supplied to the blowing part 1 via a supply hose Hs connected to the faucet of the water pipe.

[0018] The suction device 300 is connected to the suction part 2 of the hair washing device 101 via the discharge hose Ho. The suction device 300 sucks the object to be blown M from the suction part 2. In the present embodiment, mainly the used object to be blown is sucked by the suction part 2 and discharged to the suction device 300. The suction device 300 includes a storage tank 301 and a suction pump 302. The storage tank 301 stores the object to be blown M discharged to the suction device 300. The suction pump 302 sends the object to be blown M from the suction part 2 to the storage tank 301 via the discharge hose Ho. In the present embodiment, the object to be blown M is discharged to the storage tank 301 via the discharge hose Ho, becomes a liquid fluid F between the suction part 2, or between the discharge hose Ho and the storage tank 301, or in the supply tank 201, and is stored in the storage tank 301. Note that it is not limited to the above example, and the storage tank 301 may be omitted. In this case, the object to be blown M discharged from the suction part 2 may be drained to the drainage outlet of the municipal water, for example, via the discharge hose Ho.

[0019] In addition, in this embodiment, the supply device 200 and the suction device 300 are integrally waterproof and portable devices. However, the present invention is not limited to this example, and the supply device 200 and the suction device 300 may be separate.

[0020] As shown in FIGS. 3A and 3B, for example, the hair washing system 100 can be used to wash the body (hair, skin, etc.) of the user U or the cared-for person by the blown object M blown out from the blowing unit 1. The hair washing system 100 is portable and incorporates a battery 400 as described later. Therefore, the hair washing system 100 can be used outdoors as shown in FIG. 3A. In addition, the hair washing system 100 can suck and store the blown object M used for washing or the like. Therefore, the hair washing system 100 can also be used indoors as shown in FIG. 3B.

[0021] Note that the fluid F may contain, for example, essential oil. In this way, the blown object M can be scented with the mist containing essential oil or the vaporized essential oil. Therefore, the user U can use the hair washing system 100 in a relaxed state.

[0022] Alternatively, the fluid F may contain a drug such as a hair growth agent. In this way, the mist containing the drug or the vaporized drug can be sprayed onto the epidermis of the user U by the blown object M. Therefore, since the drug can effectively penetrate the epidermis, the effect of the drug can be promoted. In particular, when washing hair, the mist containing the hair growth agent or the vapor of the hair growth agent can be efficiently applied to the scalp. Therefore, an improvement in the hair growth effect can be expected.

[0023] Note that the above example does not exclude the configuration in which the fluid F is a liquid other than water.

[0024] <1-2. Control System> Next, as shown in FIG. 2, the hair washing system 100 further includes a battery 400, a power supply unit 500, a storage unit 600, and a control unit 700.

[0025] The battery 400 is the power supply unit of the hair washing system 100 and supplies power to the components that require power. The battery 400 is a rechargeable secondary battery, which is a Li-ion battery in this embodiment.

[0026] The power supply unit 500 can connect the hair washing system 100 to an external power source and receives power supply from the external power source. The external power source may be a generator or a commercial power supply network. The power supply unit 500 charges the battery 400 using the power supplied from an external device. Also, the power supply unit 500 may directly supply the power supplied from an external device to the components that require power.

[0027] The storage unit 600 is a non-transitory storage medium that maintains storage even when the power supply stops. For example, the storage unit 600 stores data and programs used by the control unit 700, and input signals output from the input unit 15 described later.

[0028] The control unit 700 receives signals output from the hair washing device 101 (such as the output signal of the input unit 15), output signals of input units (not shown) of the supply device 200 and the suction device 300, etc. Also, the control unit 700 controls the components that require control in the hair washing system 100 using the data and programs stored in the storage unit 600. For example, the control unit 700 controls the supply pump 202, the suction pump 302, the charging and discharging of the battery 400, the solenoid valve 112 (described later) of the blowing unit 1, etc.

[0029] <2. Hair washing device 101> FIG. 4 is a cross-sectional view showing a configuration example of the hair washing device 101 according to the embodiment. FIG. 5 is an external view of the hair washing device 101 with the blowing unit 1 and the suction unit 2 removed. Note that FIG. 4 shows the cross-sectional structure of the hair washing device 101 when the hair washing device 101 is virtually cut in a plane parallel to the front-rear direction including the two-dot chain line IV parallel to the vertical direction in FIG. 1.

[0030] As shown in FIG. 4, the hair washing device 101 includes a blowing unit 1 and a suction unit 2. The blowing unit 1 blows a blown body M obtained by atomizing or vaporizing a liquid-phase fluid F forward from a nozzle 13. The suction unit 2 is detachable from the blowing unit 1 and can suck the blown body M.

[0031] Since the suction unit 2 is detachable from the blowing unit 1, the hair washing device 101 can easily change the relative position of the suction unit 2 with respect to the blown body M in the blowing unit 1. Therefore, the hair washing device 101 can efficiently suck the blown body M blown from the blowing unit 1 with the suction unit 2. Also, even when the hair washing device 101 is separated from the body, it is possible to sufficiently wash the body with the blown body M while preventing the blown body M from scattering around. In particular, by opposing the suction unit 2 removed from the blowing unit 1 to the nozzle 13 with the hair sandwiched therebetween, the blown body M applied to the hair can be directly sucked by the suction unit 2. Therefore, the blown body M can be applied to the hair up to the hair tips without leakage.

[0032] Note that the blowing unit 1 can also be used as a single shower device with the suction unit 2 removed. Therefore, the hair washing device 101 can be used conveniently.

[0033] <2-1. Blowing Unit 1> The blowing unit 1 of the hair washing device 101 includes a main body unit 11, a head unit 12, a plurality of nozzles 13, a grip 14, and an input unit 15.

[0034] The main body unit 11 extends in the front-rear direction. Inside the main body unit 11, a supply flow path 111 through which the fluid F flows is arranged. The rear end of the supply flow path 111 is connected to a supply hose Hs and is connected to a supply device 200 through the inside of the supply hose Hs. The front end of the supply flow path 111 is connected to the head unit 12 and is connected to the inside of the head unit 12. Also, a solenoid valve 112 is arranged in the supply flow path 111. The solenoid valve 112 opens and closes the supply flow path 111 according to the control of the control unit 700.

[0035] In addition, a bubble generation unit 113 may be disposed in the supply channel 111. The bubble generation unit 113 generates fine bubbles in the fluid F. The fine bubbles include, for example, fine bubbles, bubbles having a diameter of less than 0.1 [mm] and not less than 1 [μm] (so-called microbubbles), and bubbles having a diameter of less than 1 [μm] (so-called ultra-fine bubbles). For example, the bubble generation unit 113 has a constricted portion 114 where the cross-sectional area of the supply channel 111 decreases, and generates fine bubbles by the Venturi effect.

[0036] For example, in the constricted portion 114, the fluid F rapidly decompresses due to the acceleration of its flow velocity. When the pressure of the fluid F becomes equal to or lower than the saturated vapor pressure, bubbles are generated by the vaporization of the fluid F. The bubbles expand after passing through the constricted portion 114, while they collapse and are refined due to a rapid increase in pressure, becoming fine bubbles with a diameter of less than 0.1 [mm].

[0037] Preferably, the bubble generation unit 113 is disposed on the head portion 12 side in the supply channel 111. By doing so, fine bubbles that disappear before reaching the nozzle 13 can be reduced. Therefore, the ejected body M ejected from the nozzle 13 can contain more fine bubbles.

[0038] However, the above examples do not exclude a configuration in which the bubble generation unit 113 is not disposed on the head portion 12 side in the supply channel 111, nor do they exclude a configuration in which the bubble generation unit 113 is not disposed in the supply channel 111.

[0039] The head portion 12 is a hollow box body extending in the left-right direction, and houses the fluid F supplied to the nozzle 13.

[0040] A plurality of nozzles 13 are disposed at the front end portion of the head portion 12. In the present embodiment, five nozzles 13 are arranged in the left-right direction. However, the present invention is not limited to this example, and the nozzle 13 may be singular or plural other than five. Further, the plurality of nozzles 13 may be two-dimensionally arranged at the front end portion of the head portion 12, for example, arranged side by side in the vertical direction and the left-right direction, respectively.

[0041] Each nozzle 13 is a mist nozzle having air holes (not shown), which mixes air with the fluid F supplied from the head portion 12 to atomize it. Thereby, the nozzle 13 atomizes the fluid F to generate the blown object M, and blows out the blown object M forward.

[0042] Note that the blowing portion 1 can change the direction in which the blown object M blows out from the nozzle 13 in the vertical direction. The head portion 12 may be rotatable in the circumferential direction about an axis (not shown) extending in the left - right direction, for example, passing through the center of the head portion 12, with respect to the main body portion 11. Alternatively, at least some of the nozzles 13 may be rotatable in the vertical direction about an axis (not shown) extending in the left - right direction, for example, passing through the base end portion of the nozzle 13, with respect to the head portion 12. In this way, for example, the direction in which the blown object M blows out can be changed to the direction toward the suction portion 2. Therefore, it becomes easier to blow out the blown object M toward the suction portion 2. However, this example does not exclude a configuration in which the direction in which the blown object M blows out from the nozzle 13 cannot be changed.

[0043] The grip 14 is a grip portion held by the user U, and protrudes outward in the left - right direction from the central portion in the front - rear direction of the main body portion 11. An input portion 15 is arranged at one end portion (for example, the left end portion) of the grip 14 in the left - right direction.

[0044] The input portion 15 receives the operation input of the user U and outputs an output signal based on the operation input to the control portion 700. The input portion 15 has, for example, an ON / OFF switch of the hair washing device 101. The control portion 700 switches the opening and closing of the electromagnetic valve 112 in response to the operation input of the ON / OFF switch. Thereby, the blowing out and the stopping of the blown object M are switched. Further, the operation input received by the input portion 15 includes adjustment of the blowing direction and the blowing intensity of the blown object M in the nozzle 13.

[0045] <2 - 2. Suction portion 2> The suction part 2 includes a cover member 21 and a connecting member 22. When the suction part 2 is attached to the blowing part 1, the cover member 21 covers at least the nozzle 13 when viewed from above. The connecting member 22 is disposed at the lower end of the cover member 21. The connecting member 22 is connected to the blowing part 1 and can be detachably attached to and detached from the blowing part 1. Specifically, the cover member 21 is attached to, for example, the upper part of the main body part 11 of the blowing part 1 by the connecting member 22.

[0046] Preferably, in a state where the suction part 2 is attached to the blowing part 1, the connecting member 22 rotatably supports the suction part 2 (particularly the cover member 21) about a rotation axis J with respect to the blowing part 1. The rotation axis J is parallel to the left - right direction. For example, the connecting member 22 has a rotating part that rotatably supports the outer peripheral part with respect to the inner peripheral part. In this way, even when the suction part 2 is attached to the blowing part 1, the relative position of the suction part 2 with respect to the blowing part 1 can be changed. However, this example does not exclude a configuration in which the cover member 21 of the suction part 2 is non - rotatable with respect to the blowing part 1 when the cover member 21 of the suction part 2 is attached to the blowing part 1.

[0047] The cover member 21 includes a top plate part 211, a front plate part 212, side plate parts 213, a rear plate part 214, and a bottom plate part 215.

[0048] In a state where the suction part 2 is attached to the blowing part 1, the top plate part 211 is disposed above the nozzle 13 and extends in a direction intersecting the vertical direction.

[0049] In a state where the suction part 2 is attached to the blowing part 1, the front plate part 212 is disposed in front of the nozzle 13. In this state, the front plate part 212 protrudes downward from the front end part of the top plate part 211 and extends in the left - right direction along the front end part of the top plate part 211. Preferably, in a state where the suction part 2 is attached to the blowing part 1, at least a part of the blow - out port 131 of the nozzle 13 faces the front plate part 212 in the front - rear direction. More preferably, the entire blow - out port 131 of the nozzle 13 faces the front plate part 212 in the front - rear direction. By doing so, it becomes easier for the blown - out object M blown out from the blow - out port 131 of the nozzle 13 to be received by the front plate part 212. Therefore, the suction efficiency of the blown - out object M in the suction part 2 can be improved. Also, the scattering of the blown - out object M forward of the front plate part 212 can be effectively suppressed or prevented.

[0050] In a state where the suction part 2 is attached to the blowing part 1, the side plate part 213 is disposed outside the nozzle 13 in the left - right direction. In this state, the side plate part 213 protrudes downward from the left - right direction end part of the top plate part 211 and extends along the left - right direction end part of the top plate part 211. In the present embodiment, the side plate parts 213 are a pair on the left and right. The left - hand side plate part 213 protrudes downward from the left end part of the top plate part 211 and extends in the front - rear direction along the left end part of the top plate part 211. The right - hand side plate part 213 protrudes downward from the right end part of the top plate part 211 and extends in the front - rear direction along the right end part of the top plate part 211. By doing so, the side plate part 213 can effectively suppress the scattering of the blown - out object M to the outside in the left - right direction of the hair - washing device 101. In the present embodiment, the pair of left - and - right side plate parts 213 can effectively suppress the scattering of the blown - out object M to both sides in the left - right direction of the hair - washing device 101.

[0051] The rear plate part 214 is disposed behind the nozzle 13 in a state where the suction part 2 is attached to the blowing part 1. In this state, the rear plate part 214 protrudes downward from the rear end part of the top plate part 211 and extends in the left - right direction along the rear end part of the top plate part 211.

[0052] The bottom plate portion 215 is disposed above the main body portion 11 and below the top plate portion 211 in a state where the suction portion 2 is attached to the blowing portion 1, and extends in a direction intersecting the vertical direction. The rear end portion of the bottom plate portion 215 is connected to the lower end portion of the rear plate portion 214. Further, in the present embodiment, the left end portion of the bottom plate portion 215 is connected to the left side plate portion 213, and the right end portion of the bottom plate portion 215 is connected to the right side plate portion 213.

[0053] Further, a suction port 216 and a discharge port 217 are disposed in the cover member 21.

[0054] The suction port 216 is an opening for sucking the object to be blown M, and is disposed at the lower portion of the cover member 21. In the present embodiment, the suction port 216 is an opening surrounded by the lower end portion of the front plate portion 212, the lower end portions of the pair of left and right side plate portions 213, and the front end portion of the bottom plate portion 215.

[0055] The discharge port 217 is an opening for discharging the object to be blown M sucked from the suction port 216 from the suction portion 2. Specifically, a discharge pipe 218 is connected to the discharge port 217. The discharge pipe 218 is connected to one end of the discharge hose Ho. The other end of the discharge hose Ho is connected to the suction device 300. In the present embodiment, the discharge port 217 is disposed in the rear plate portion 214. However, it is not limited to this example, and the discharge port 217 may be disposed in any of the top plate portion 211, the front plate portion 212, the side plate portion 213, and the bottom plate portion 215.

[0056] In a state where the suction portion 2 is attached to the blowing portion 1, the outer edge portion on the front side of the suction port 216 is located in front of the nozzle 13. In this way, in this state, the suction portion 2 can suck the object to be blown M blown forward from the suction port 216 above the nozzle 13 and discharge it from the discharge port 217 to the outside of the suction portion 2. The object to be blown M is discharged to the suction device 300.

[0057] Also, preferably, at least a part of the suction port 216 has a mesh shape or a perforated shape formed by a plurality of through holes. For example, the suction part 2 further has a passing plate 219. The passing plate 219 covers the suction port 216. At least a part of the shape of the passing plate 219 is either a mesh shape or a perforated shape having a plurality of through holes.

[0058] In this way, it is possible to suppress or prevent a part of the user U's body (such as a finger or hair) from entering the inside of the cover member 21 through the suction port 216. Therefore, the user U can safely use the suction part 2. In addition, the intrusion of foreign matters (such as dust and fallen hairs) can also be suppressed or prevented, so that the foreign matters can be suppressed or prevented from blocking the suction port 216, the inside of the cover member 21, the discharge port 217, etc. (especially clogging these). Therefore, a decrease in the suction force of the suction part 2 can be suppressed or prevented.

[0059] However, the above example does not exclude a configuration in which the entire suction port 216 is not in a mesh shape and is not a perforated shape composed of a plurality of through holes. For example, the passing plate 219 may be omitted, and the suction port 216 may not be covered by the passing plate 219.

[0060] In addition, in this embodiment, as described above, the cover member 21 has the side plate portion 213 and the bottom plate portion 215. However, this example does not exclude a configuration in which the cover member 21 does not have the side plate portion 213, nor does it exclude a configuration in which the cover member 21 does not have the bottom plate portion 215. In the latter case, the opening surrounded by the lower end portion of the front plate portion 212, the lower end portions of the pair of left and right side plate portions 213, and the lower end portion of the rear plate portion 214 becomes the suction port 216.

[0061] <3. First Modified Example of the Hair Washing Device 101> Next, with reference to FIG. 6, a first modification of the hair washing device 101 will be described. FIG. 6 is a cross-sectional view showing a configuration example of the hair washing device 101a according to the first modification. Note that FIG. 6 corresponds to the cross-sectional structure of the hair washing device 101 when the hair washing device 101 is virtually cut along a plane parallel to the front-rear direction including the two-dot chain line IV parallel to the vertical direction in FIG. 1. Hereinafter, for the hair washing device 101a according to the first modification, the configurations different from those of the above-described embodiment will be described. In addition, among the components of the hair washing device 101a according to the first modification that are the same as those of the above-described embodiment, the same reference numerals may be given, and the description thereof may be omitted. Further, the configuration of the first modification described below can be implemented in combination with the configuration of the above-described embodiment as long as there is no particular contradiction.

[0062] In the hair washing device 101a according to the first modification, the top plate portion 211a, the front plate portion 212a, the side plate portion 213a, and the rear plate portion 214a of the cover member 21 are each hollow. Their interiors are connected to each other.

[0063] In addition, a suction port 216a and a discharge port 217 are arranged in the cover member 21. The suction port 216a is an opening for sucking the object to be blown M. The discharge port 217 is an opening for discharging the object to be blown M sucked from the suction port 216a from the suction unit 2, and is connected to the suction device 300. In the hair washing device 101a according to the first modification, the discharge port 217 is arranged at the rear end surface of the rear plate portion 214a.

[0064] Preferably, the suction port 216a is arranged at the rear end surface of the front plate portion 212a. Specifically, at least one suction port 216a connected to the discharge port 217 is arranged in at least a part of the region of the rear end surface of the front plate portion 212a. For example, in the present embodiment, the rear end portion of the front plate portion 212a (that is, the entire region of the rear end surface of the front plate portion 212a) serves as one suction port 216a.

[0065] In this way, the suction part 2 can suck the object M to be blown out into the inside from the rear end surface of the front plate part 212a inside the cover member 21. The suction port 216a of the front plate part 212a is arranged deeper inside the cover member 21 than the opening 21a formed on the lower surface of the cover member 21. Therefore, it becomes difficult for a part of the user U's body (such as a finger or hair) to hit the suction port 216a of the front plate part 212a, and it is possible to more effectively suppress or prevent entry into the inside from the suction port 216a.

[0066] Also, preferably, the suction port 216a is arranged on the side surface of the side plate part 213a on the nozzle 13 side in the left-right direction. At least one suction port 216a connected to the discharge port 217 is arranged in at least a part of the region of the side surface of the side plate part 213a on the nozzle 13 side in the left-right direction. In this embodiment, the right side part of the left side plate part 213a (that is, the entire region of the right side surface of the left side plate part 213a) serves as one suction port 216a. Also, the left side part of the right side plate part 213a (that is, the entire region of the left side surface of the right side plate part 213a) serves as one suction port 216a.

[0067] In this way, the suction part 2 can suck the object M to be blown out into the inside from the inner side surface in the left-right direction of the side plate part 213a inside the cover member 21. The suction port 216a of the side plate part 213a is arranged deeper inside the cover member 21 than the opening 21a formed on the lower surface of the cover member 21. Therefore, it becomes difficult for a part of the user U's body (such as a finger or hair) to hit the suction port 216a of the side plate part 213a, and it is possible to more effectively suppress or prevent entry into the inside from the suction port 216a.

[0068] Also, preferably, the suction port 216a is arranged on the lower surface of the top plate part 211a. Specifically, at least one suction port 216a connected to the discharge port 217 is arranged in at least a part of the region of the lower surface of the top plate part 211. In this embodiment, the lower end part of the top plate part 211a (that is, the entire region of the lower surface of the top plate part 211a) serves as one suction port 216a.

[0069] By doing so, the suction part 2 can suck the object M to be blown out from the lower surface of the top plate part 211a into its interior inside the cover member 21. The suction port 216a of the top plate part 211a is arranged deeper inside the cover member 21 than the opening 21a formed on the lower surface of the cover member 21. Therefore, it becomes difficult for a part of the user U's body (such as a finger or hair) to hit the suction port 216a of the top plate part 211a, and it is possible to more effectively suppress or prevent entry into the interior from the suction port 216a.

[0070] In addition, in the hair washing device 101a according to the first modification example, the suction port 216a is arranged on all of the lower surface of the top plate part 211a, the rear end surface of the front plate part 212a, and the side surface on the nozzle 13 side in the left - right direction of the side plate part 213a. However, it is not limited to this example, and the suction port 216a may not be arranged on at most two of these. In other words, as long as the suction port 216a is arranged on at least one of these.

[0071] That is, the suction port 216a is arranged on any one of the lower surface of the top plate part 211a, the rear end surface of the front plate part 212a, and the side surface on the nozzle 13 side in the left - right direction of the side plate part 213a, and may not be arranged on the remaining two. Alternatively, the suction port 216a is arranged on any two of the lower end part of the top plate part 211a, the rear end surface of the front plate part 212a, and the side surface on the nozzle 13 side in the left - right direction of the side plate part 213a, and may not be arranged on the remaining one.

[0072] Also, preferably, at least a part of the suction port 216a has a mesh shape or a perforated shape composed of a plurality of through - holes. For example, in the hair washing device 101a according to the first modification example, instead of the through - plate 219 in the above - mentioned embodiment, the suction part 2 has a through - plate 219a. At least a part of the shape of the through - plate 219a is either a mesh shape or an effective shape having a plurality of through - holes.

[0073] By doing so, it is possible to suppress or prevent a part of the user U's body (such as a finger or hair) from entering the internal space of at least any one of the top plate portion 211a, the front plate portion 212a, and the side plate portion 213a through the suction port 216a. Therefore, the user U can safely use the suction unit 2. In addition, since the intrusion of foreign matters (such as dust and fallen hair) can also be suppressed or prevented, it is possible to suppress or prevent the foreign matters from blocking the internal space of the suction port 216a, the top plate portion 211a, the front plate portion 212a, and the side plate portion 213a, the discharge port 217, etc. (especially clogging these). Therefore, it is possible to suppress or prevent a decrease in the suction force of the suction unit 2.

[0074] However, the above examples do not exclude a configuration in which the entire suction port 216a is not in a mesh shape and is not a perforated shape composed of a plurality of through holes. For example, in at least any one of the top plate portion 211a, the front plate portion 212a, and the side plate portion 213a, the passing plate 219 may be omitted, and the suction port 216a in at least any one of the top plate portion 211a, the front plate portion 212a, and the side plate portion 213a may not be covered by the passing plate 219. Also, in at least any one of the top plate portion 211a, the front plate portion 212a, and the side plate portion 213a, the suction port 216a may be omitted. Further, one or at most two of the top plate portion 211a, the front plate portion 212a, and the side plate portion 213a may not be hollow.

However, the present invention is not limited to this example, and at most two of these may not be provided with the suction ports 216b. In other words, as long as the suction ports 216b are arranged in at least one of these.

[0077] Even in this case, it is possible to suppress or prevent a part of the user U's body (such as fingers, hair, etc.) from entering the internal space of at least any one of the top plate portion 211b, the front plate portion 212b, and the side plate portion 213b through the suction ports 216b. Therefore, the user U can safely use the suction unit 2. In addition, the intrusion of foreign matters (such as dust, fallen hair, etc.) can also be suppressed or prevented, so that it is possible to suppress or prevent the foreign matters from blocking the suction ports 216b, the internal spaces of the top plate portion 211b, the front plate portion 212b, and the side plate portion 213b, the discharge port 217, etc. (especially clogging these).
