Specifically, when the hair is blown with hot air, the hair is heated and the hydrogen bonds between the hair fibers are cut. Therefore, when the hair is being blown by the hot air (when the hydrogen bonds between the hair fibers are cut), the hair can be more easily formed into a desired shape (straight shape, etc.) . On the other hand, when a cold air is blown to the hair in which the hydrogen bonds between the hair fibers are cut, the hair is cooled and the hydrogen bonds between the hair fibers are in a state. Therefore, when the hair that has been arranged in a desired shape is cooled by blowing cold air, the hair fibers are hydrogen-bonded in a state in which the hair has been arranged in the desired shape, and it becomes possible to maintain the hair in the desired shape.

In this way, if the hot air and the cold air are alternately discharged from the discharge port, the hair can be shaped into a desired shape, and the hair care effect can be improved.

The energization time of the energization is 3 seconds or less, and the product of the electric power input to the heating part and the energization time is 1000 W·s or more.

In this way, the hair temperature (hair temperature that can cut hydrogen bonds between hair fibers) required for straightening hair and the like can be obtained in a relatively short period of time, and the hair tail can be easily styled. It becomes possible to further improve the hair care effect.

Moreover, it is comprised so that it can be folded, and when using, the grip part 1a and the main body part 1b can show a substantially T shape or a substantially L shape (substantially T shape in this Embodiment 1) appearance.

The power cord 2 is pulled out from the protruding end of the grip portion 1a. Also, the grip portion 1a is divided into a base portion 1c and a front end portion 1d on the side of the body portion 1b, and the base portion 1c and the front end portion 1d are rotatably connected via a connecting portion 1e. In addition, the front-end|tip part 1d is comprised so that it can be folded up to the position along the main-body part 1b.

The casing 3 constituting the outer wall (constituting the outer casing) of the blower 1 is constituted by joining a plurality of divided bodies. A cavity is formed inside the casing 3, and various electrical components are accommodated in the cavity.

The inside of the main body part 1b is formed with a wind tunnel (air supply flow path) 4 which is an inlet opening from one side (right side) in the longitudinal direction (the left-right direction in FIG. 3 ) of the main body part 1b The air blower 5 is accommodated in the wind tunnel 4 (suction port) 4a to the outlet opening (discharge port) 4b. The blower 5 includes a fan 5a and a motor 5b, and the motor 5b rotates the fan 5a. And by driving the motor 5b and rotating the fan 5a, the air flow W can be formed. The air flow W flows into the wind tunnel 4 from the outside through the inlet opening 4a, and mainly passes through the inside of the wind tunnel 4 and is discharged to the outside from the outlet opening 4b.

In the first embodiment, the inlet opening (suction port) 4a is covered with a mesh-shaped frame 81, and the shape of the opening of the frame 81 is a honeycomb shape. Further, as shown in FIG. 3 , the frame body 81 is integrally formed with a mesh 82 having an aperture ratio of about 55 to 90% and a mesh width of about 300 to 650 μm. For this mesh 82, a flame-retardant resin such as metal or polyester can be used, and by integrally molding the mesh 82 with a fine mesh width in this way, it is possible to more reliably prevent fine dust, hair, etc. from entering the air passage. Inside.

In addition, in the main body portion 1b, a substantially cylindrical inner tube 6 is provided inside the outer tube 3a of the casing 3, and the air flow W mainly flows inside the inner tube 6. As shown in FIG. Inside the inner cylinder 6, a fan 5a is arranged on the most upstream side, a motor 5b for driving the fan 5a is arranged on the downstream side, and a heater 8 as a heating unit is arranged on the further downstream side of the motor 5b.

In addition, when the heater 8 is activated, the hot air is blown out from the outlet opening 4b. In addition, in this Embodiment 1, although the heater 8 is comprised so that the strip|belt-shaped and corrugated sheet-shaped resistor body may be wound and arrange|positioned along the inner periphery of the inner cylinder 6, it is not limited to this structure.

The inner tube 6 has: a cylindrical portion 6a; a plurality of support ribs 6b (only one of which is shown in FIG. 3 ) extending radially outward from the cylindrical portion 6a and distributed in the circumferential direction; and a flange portion 6c, The permeable support rib 6b is connected to the cylindrical portion 6a, and protrudes in a direction substantially orthogonal to the axial direction of the cylindrical portion 6a.

Further, a gap g1 is formed between the cylindrical portion 6a and the flange portion 6c, and a part of the air flow W is branched through the gap g1 to flow into the cavity 9 (a branched flow is formed). In addition, the gap g1 which becomes the branch flow to the introduction port in the cavity 9 is provided in the downstream of the fan 5, and the position which becomes the upstream of the heater 8. As shown in FIG. Therefore, the branched flow becomes a relatively cool air flow before being heated by the heater 8 .

In addition, the branched flow that has flowed into the cavity 9 is partially branched again, and is blown out from the outer peripheral portion of the outlet opening 4b through the space between the inner tube 6 and the casing 3 . A part of this branched flow becomes an air flow that passes through the inner tube 6 and the casing instead of passing through the metal fine particle outlet (charged particle outlet) 20a and 20b or the mist outlet (charged particle outlet) 20c to be described later. The relatively cool air flow between the bodies 3 is blown out from the outer peripheral portion of the outlet opening 4b.

In the first embodiment, a substantially arc-shaped through-hole (opening) 3b is formed at a position on the side of the outlet opening 4b of the cavity 9 in the casing 3, and the through-hole 3b is blocked by the cover 20. The cover 20 is made of an insulating synthetic resin material. The cover 20 is attached to the casing 3 by being moved from the downstream side to the upstream side with respect to the casing 3 .

Moreover, it is comprised so that the substantially cylindrical outer side blowing nozzle 20f is integrally formed on the downstream side of the cover 20, and when the cover 20 is attached to the casing 3, the outer side blowing nozzle 20f is used for The outer circumference of the outlet opening 4b is defined.

In addition, the inner nozzle 21 is attached to the downstream end of the inner cylinder 6, the inner nozzle 21 has a substantially cylindrical shape with a diameter smaller than that of the outer nozzle 20f, and the downstream side of the inner nozzle 21 is opened. would be part of the outlet opening 4b.

In this way, in the first embodiment, the inner nozzle 21 is attached to the downstream end of the inner cylinder 6, and the cover 20 is attached to the casing 3, whereby the outer nozzle 20f and the inner nozzle 21 are configured to A mouthpiece that forms a double barrel structure.

Therefore, although most of the air flow W formed by driving the blower 5 is introduced into the inner tube 6 and becomes the main air flow W1 blown out from the opening of the inner nozzle 21 (the center of the outlet opening 4b), However, a part of the air flow W becomes the branch flow W2 or the branch flow W3. In addition, the branched flow W2 flows into the cavity 9 and does not pass through the metal fine particle blowing ports 20a and 20b or the mist blowing port 20c, but from between the outer nozzle 20f and the inner nozzle 21 (the outer peripheral side of the outlet opening 4b). ) air flow being blown out. In addition, the branch flow W3 is an air flow which flows into the cavity 9 and is blown out from the metal fine particle blowing ports 20a and 20b or the mist blowing port 20c.

In addition, in the first embodiment, the main air flow W1 is blown out from the two window portions (the first window portion 231 and the second window portion 232 ) formed in the inner side nozzle 21 (see FIGS. 5A and 232 ). 5B and Figure 7).

Specifically, the inner mouthpiece 21 includes: a main body part 210, which is substantially cylindrical; and a beam part 220, which divides the internal space of the main body part 210 into two spaces. The beam portion 220 is formed to extend in the vertical direction at the center portion in the left-right direction of the main body portion 210 . By doing so, it is comprised so that the window parts 231 and 232 may be formed on the left and right sides of the inner mouthpiece 21, respectively.

Furthermore, a plurality of attachment pieces 211 are formed on the outer periphery of the main body 210 , and the inner nozzle 21 is attached to the inner tube 6 by engaging the attachment pieces 211 with the inner tube 6 .

Moreover, as shown in FIG. 7, the beam part 220 is formed so that the shape of a horizontal cross section may become a substantially U shape. That is, the pair of left and right wall portions 221 and 221 formed on the downstream side of the beam portion 220 extend substantially in parallel in the front-rear direction (air blowing direction).

By using the inner nozzle 21 having such a structure and blowing out the air flow from the two window portions 231 and 232, the wind (hot air or cold air) can be blown to the hair more evenly. In addition, if the wind is blown to the hair more evenly, the hair can be appropriately loosened (distributed), so that the drying performance of the hair can be further improved.

However, when the inner nozzle 21 shown in FIGS. 5A and 5B is used to discharge air from the outlet opening 4b, a negative pressure is generated in the vicinity of the downstream side of the beam portion 220. Therefore, even if the main air flow W1 blown from the inner mouthpiece 21 is branched into two air flows (two air beams), the two air flows meet at a relatively early stage (see FIG. 7 ). Therefore, when the inner nozzle 21 shown in FIGS. 5A and 5B is used, there is a high possibility that almost one bundle of air flows to the hair, and the drying performance of the hair cannot be improved in some cases.

Therefore, it is preferable to replace the inner mouthpiece 21 with the inner mouthpiece 21A shown in FIGS. 6A , 6B and 8 .

The inner nozzle 21A also includes: a main body part 210A, which has a substantially cylindrical shape; The portion extends in the up-down direction. In this way, the window portions 231A and 232A are formed on the left and right sides of the inner nozzle 21A, respectively.

Moreover, it is comprised so that several attachment piece part 211A is formed in the outer periphery of main-body part 210A, and the inner side nozzle 21A is attached to the inner cylinder 6 by engaging this attachment piece part 211A with the inner cylinder 6.

Here, as shown in FIG. 8, in 21 A of inner side nozzles, the beam part 220A is formed so that a horizontal cross-sectional shape may become a substantially V shape. That is, the pair of left and right wall portions 221A, 221A formed on the downstream side of the beam portion 220A are provided so as to be separated from each other as they go toward the downstream side. By doing so, the main air flow W1 blown out from the inner nozzle 21 is configured to branch into two air flows (two air beams) more reliably.

In addition, in the inner nozzle 21A, grooves 212A and 212A recessed toward the center are formed on the upper and lower ends of the main body 210A, respectively, and the grooves 212A and 212A are formed so that the grooves on the downstream side are deeper than those on the upstream side. The groove is deeper.

Furthermore, after the grooves 212A and 212A are provided in the main body 210A, when the air is discharged from the outlet opening 4b, the branch flow W2 flows to the center portion on the downstream side of the beam portion 220A, and the branch flow W2 flows from the outside. Between the mouthpiece 20f and the inner mouthpiece 21 (outer peripheral side of the outlet opening 4b) blowing out. Therefore, the negative pressure generated in the vicinity of the downstream side of the beam portion 220A can be alleviated.

In this way, when the inner nozzle 21A is used in place of the inner nozzle 21, the generation of negative pressure in the vicinity of the downstream side of the beam portion 220A is suppressed, so that it is possible to more reliably maintain the bifurcated air flow (two air jets). )status. As a result, the hair can be blown with two air streams (two air beams), and the hair can be appropriately unwound (distributed), so that the drying performance of the hair can be further improved.

In addition, in the main body portion 1b, in the cavity 9 formed between the casing 3 and the inner cylinder 6, two (plurality) metal fine particle generating units (ion generating units: charged particle generating units) 30 are accommodated, 40 ; a mist generation unit (ion generation unit: charged particle generation unit) 50 ; and a voltage application circuit 12 for applying a voltage to the mist generation unit 50 . In addition, a voltage application circuit 13 that applies a voltage to the metal fine particle generating parts 30 and 40 is accommodated in a part of the cavity 9 that is different from the part where the voltage application circuit 12 is accommodated.

The voltage application circuit 12 and the voltage application circuit 13 are preferably arranged in the grip portion 1a, or in a region in the body portion 1b that is an extension of the grip portion 1a. This is because when the user holds the grip portion 1a, the torque due to the mass of the voltage application circuit 12 and the voltage application circuit 13 is reduced, thereby reducing the load on the user's hand.

In addition, it is preferable to arrange the voltage application circuit 12 and the voltage application circuit 13 at positions on the opposite side to each other by sandwiching the inner cylinder 6 . In this way, inconveniences such as voltage drop or instability due to the mutual interference between the voltage application circuit 12 and the voltage application circuit 13 can be suppressed.

In addition, in the first embodiment, the side surface portion of the main body portion 1b (the portion of the cavity 9 that is different from the portion where the voltage application circuit 12 is housed) is provided with a switch portion (air blowing mode selection portion) 19, which switch portion The (air supply mode selection unit) 19 performs switching (selection) between hot air and cold air, selection of an operation mode, and the like.

Moreover, the front-end|tip part 1d of the grip part 1a is provided with the different switch part (air blowing mode selection part) 16, and this switch part 16 performs switching on and off of a power supply, etc. These electrical components are connected by the lead wire 17 which coats the core wire which consists of a metal conductor etc. with insulating resin etc.,.

In addition, the lead wire 17 connected to the metal fine particle generating part 30, the lead wire 17 connected to the metal fine particle generating part 40, and the lead wire 17 connected to the mist generating part 50 are wired so as not to cross each other and to be separated as much as possible. ideal. This is to suppress the situation in which the desired voltage cannot be obtained in the metal fine particle generating parts 30 and 40 or the mist generating part 50 due to the mutual interference of the currents flowing in the different wires 17, or the voltage becomes unstable situation.

In this Embodiment 1, the switch part 16 is comprised so that the opening/closing state of an internal contact can be switched by operating the operating element 16a exposed on the surface of the casing 3. FIG. At this time, by sliding the operating element 16a in the up-down direction, the open/close state of the internal contact can be switched in multiple stages.

For example, it can be configured to be switchable among four modes of power off, weak wind, moderate wind, and strong wind. At this time, the state where the operating element 16a is located at the lowermost part can be set as the power-off.

In addition, when the operating element 16a is slid upward from the lowermost part for one stage, the power supply can be turned on, and weak wind can be sent out. Furthermore, when the operation element 16a is further slid upward for one stage, a stroke can be sent out, and when the operation element 16a is slid to the uppermost part, a strong wind can be sent out.

On the other hand, the switch portion 19 for switching between hot air and cold air, operating modes, etc. is configured to switch the opening and closing of the internal contact by operating (pressing) an operating member 19a formed on the surface (side surface) of the casing 3 . state. In addition, a display portion 14 is formed above the operating element 19, and the display portion 14 displays the currently selected mode.

The switch parts 19 , the display part 14 and the like are electrically connected to the control part 10 .

In the first embodiment, by operating the operating element 19, four air temperature modes of "HOT (heat)", "cold heat", "COLD (cold)", and "SCALP (scalp)" can be switched. In this case, the display unit 14 is configured to display characters or the like that can recognize the selected mode.

Hereinafter, each mode and an example of the display method on the display unit 14 will be described.

The so-called "HOT (heat)" is a mode of outputting hot air, and is a mode in which the temperature of the wind blowing on the hair becomes about 70°C to 80°C during normal use. It can be configured that when the mode for outputting hot air is selected here, the character "HOT (heat)" is displayed on the display unit 14 .

In addition, the so-called "cold and heat" is a mode in which hot air and cold air are alternately output, such as (hot air for 5 seconds, cold air for 7 seconds) or (hot air for 2 seconds, cold air for 6 seconds). When the "hot and cold" mode is selected, arrows are displayed on the display unit 14, and "HOT" and "COLD" are alternately displayed in accordance with the output of hot air and cold air. .

In addition, the so-called "COLD (cold)" is a mode for outputting cold air, and is a mode in which the temperature of the wind blowing on the hair becomes about 30°C during normal use. It is possible to configure the display unit 14 to display the characters "COLD" when the mode for outputting cold air is selected here.

In addition, the so-called "SCALP (scalp)" is a mode for outputting low-temperature wind, and is a mode in which the temperature of the wind blowing on the hair becomes about 50°C during normal use. This "SCALP (scalp)" mode is mainly set as a mode to be selected when performing scalp care. In addition, when the "SCALP (scalp)" mode is selected, the characters "SCALP (scalp)" can be displayed on the display unit 14 .

In addition, when the operating member 16a is slid upward and the power is turned on, the control unit 10 is energized, the heater 8 is driven by the drive signal corresponding to the current air blowing mode, and the display of the display unit 14 is displayed on the control to display the current air supply mode. In addition, when the operating member 16a is slid upward and the power is turned on, the "HOT (hot)" mode is selected, and hot air is sent out.

Furthermore, each time the operating member 19a is operated, a depression signal is sent to the control unit 10, so that the four air temperature states are in the "cold and hot" mode, "COLD (cold)" mode, "SCALP (scalp)" ” mode and “HOT” mode are switched in order.

In addition, in the first embodiment, the characters "SKIN (skin)" are formed on the display unit 14, and when "COLD (cold)" is selected in the low wind mode, "SKIN (skin)" is displayed. Displayed together with "COLD".

That is, when "COLD" is selected in the weak wind mode, it can be used as the "SKIN" mode. In addition, the "SKIN" mode is a mode selected for skin care, such as blowing the skin with cold air containing mist, etc., to bring the skin's moisture and moisture to an appropriate state, etc. .

In addition, the above description is only an example, and various methods can be used as the display method of each mode. Moreover, regarding the switching mode of hot air and cold air, setting of various modes is possible.

Moreover, as described above, in the cover 20, the metal fine particle blowing ports (ion emission ports) 20a and 20b and the mist blowing port (ion emission port) 20c are formed independently of each other.

Furthermore, the ion flow path 4c for supplying ions to flow is formed in front of the mist generating part (ion generating part: charged particle generating part) 50 and the metal fine particle generating parts (ion generating part: charged particle generating part) 30 and 40. , the metal fine particle blowing ports (ion emission ports) 20a and 20b and the mist blowing port (ion emission port) 20c are provided on the downstream side of the ion flow path 4c.

In addition, in order to suppress the electrification by metal fine particles or mist, it is desirable that the cover 20 lowers the conductivity lower than that of the case 3 . This is because when the cover 20 is charged, the charged metal fine particles, negative ions, or mist are less likely to be discharged from the metal fine particle generating units 30 and 40 or the mist generating unit 50 due to the charge.

In order to suppress the electrification of the cover 20 , the cover 20 is formed of a material that does not easily cause electrification, such as PC (polycarbonate: polycarbonate) resin. Also, in this section, the cover 20 constitutes the outer profile of the hair dryer 1 .

In addition, it is also possible to configure the cover 20 to remove static electricity by bringing the cover 20 into contact with the electrodes of the mist generation part (ion generation part: charged particle generation part) 50 .

Moreover, in this Embodiment 1, the hole diameter of the metal fine particle blowing port 20a, 20b is narrowed smaller than the hole diameter of the mist blowing port 20c. That is, maintenance of the mist generating part 50 passing through the mist blowing port 20c, checking of the state, etc. can be performed more easily, and erroneous entry of fingers or tools through the metal fine particle blowing ports 20a and 20b can be suppressed.

Moreover, in this Embodiment 1, the metal fine particle blowing port (ion emission port) 20a, 20b is formed in the peripheral part 20d of the mist blowing port 20c.

Specifically, the metal fine particle blowing port 20a and the metal fine particle blowing port 20b are arranged side by side so that the mist blowing port 20c becomes the center.

That is, in the cover 20, the metal fine particle blowing ports 20a and 20b and the mist blowing port 20c are formed as the metal fine particle blowing port 20a and the mist blowing port in the width direction of the blower 1 (the left-right direction in FIG. 2 ). 20c and the metal fine particle blowing port 20b are arranged in the order.

By adopting such an arrangement, the negatively charged mist can be suppressed from being diffused (scattered) to the outside due to the negative ions blown out from the metal fine particle blowing ports (ion discharge ports) 20a and 20b, which are It is formed in the peripheral part 20d of the mist blowing port 20c.

As a result, the straightness of the mist is improved, the mist can easily reach the hair, and the hair care effect can be further enhanced.

Moreover, the wall part 20e is provided in the downstream side of the mist blowing outlet 20c, and the lower part, and this wall part 20e is extended in the blow-out direction of mist. Moreover, by providing this wall part 20e, it is comprised so that the mist blown out from the mist blowing port 20c can be suppressed from spreading (scattering) downward.

In addition, the metal fine particle generating parts 30 and 40 and the mist generating part 50 are formed by the metal fine particle generating part 30 , the mist generating part 50 and the metal fine particle generating part in the width direction (the left-right direction in FIG. 2 ) of the blower 1 in the cavity 9 The order of 40 is arranged side by side.

Furthermore, a shielding plate (partitioning portion) 6d is provided between the mist generating portion 50 and the metal fine particle generating portions (negative ion generating portions) 30 and 40 adjacent to the mist generating portion 50 .

Further, as shown in FIG. 4 , by arranging the shielding plate 6d so as to extend in the vertical direction of the blower 1 and the blowing direction of the mist (the left and right direction in FIG. 4 ), the metal particles or mist are suppressed from being discharged from the metal particle outlet. 20a, 20b and the mist blowing port 20c are mixed before being blown out.

At this time, the amount of charged particles generated in the second charged particle generation amount control mode is configured to be larger than the amount of charged particles generated in the first charged particle generation amount control mode. That is, when the cold air which increases the resistance value of the hair has been blown (when the hair is drying or when the temperature of the hair is low), the amount of generated charged particles is reduced.

As described above, in the first embodiment, the amount of the generated charged particles is controlled in accordance with the change in the electrical conductivity of the hair surface, whereby static electricity can be removed more stably.

Although the preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described first embodiment, and various modifications are possible.

For example, as shown in FIG. 14, this invention can also be applied to the hair dryer 1B with a comb as a heating blower.

The hair dryer 1B with a comb is formed in a rod shape, and the user can hold the grip portion 1a and set the hair (comb the hair) by touching the comb portion 23 provided at the front end portion 1g with the hair. In the comb part 23, a plurality of bristles 23a are protrudingly provided.

The casing 3B constituting the outer wall (constituting the outer shell) is constituted by joining a plurality of divided bodies, and a wind tunnel (air flow passage) 9B is formed in the casing 9B, and various electrical components are accommodated in the wind tunnel 9B.

In addition, a cover 20B is attached to the portion of the grip portion 1a close to the comb portion 23, and the cover 20B constitutes a bulging outer wall (constructs an outline), and is formed by the cover 20B and the case 3B. Inside the wind tunnel 9B, the metal fine particle generating parts 30 and 40 and the mist generating part 50 are accommodated.

The cover 20B has discharge ports 20a and 20b that are opened toward the bristles 23a, and the metal fine particles generated by the metal fine particle generating units 30 and 40 and the mist generated by the mist generating unit 50 will pass through the discharge port 20a. , 20b are released to the outside and act on the hair or skin. In addition, a voltage is applied from the circuit part 24 to the metal fine particle generation parts 30 and 40 and the mist generation part 50 .

In addition, a fan 5B and a motor 7B are provided in the wind tunnel 9B, the fan 5B generates the air flow W, the motor 7B rotates the fan 5B, and the particles generated by the metal fine particle generating units 30 and 40 can be generated. The metal fine particles and the mist generated by the mist generating unit 50 are discharged along the branch flow Wp.

The motor 7B and the fan 5B are accommodated in the wind tunnel 9B formed in the casing 3B. The motor 7B is rotationally driven by a drive circuit included in the circuit portion 24 .

An opening 1h is formed on the base end side (lower side in FIG. 14 ) of the casing 3B, and the opening 1h serves as an air intake port. After the fan 5B is rotated, the air flows into the wind tunnel 9B through the opening 1h from the outside. air flow W that is discharged toward the comb part 23 through the inside of the wind tunnel 9B is formed. The air flow W is blown out from the blow-out hole (discharge port) 23b formed in the root of the bristles 23a of the comb part 23 .

In addition, in order to prevent the discharge of the metal fine particles from being hindered by the user's electrification, the electrification portion (the electrification imparting plate) 1f is exposed on the surface of the grip portion 1a.

In addition, the shielding wall 22B is provided to prevent the mist generated by the mist generation part 50 from reaching the metal fine particle generation parts 30 and 40 .

In addition, in the above-mentioned Embodiment 1, although the metal fine particle generating part which produces|generates metal fine particles and negative ions is illustrated as an ion generating part, it is also possible to use a device which does not generate metal fine particles, but only generates negative ions.

In addition, the present disclosure can also be applied to an ion generator that generates positive ions. In this way, when positive ions are generated, it is effective when used for hair to which artificial hairs such as wigs are joined. This is because artificial hairs such as wigs tend to be negatively charged, so by supplying positive ions, the generation of static electricity can be suppressed.

Moreover, in the said Embodiment 1, although the example in which two metal fine particle blowing ports (ion discharge ports) were formed was illustrated, three or more metal fine particle blowing ports (ion discharge ports) may be formed.

In addition, in the above-mentioned Embodiment 1, although the example in which the metal fine particles and the mist are blown out by the branch flow is illustrated, even when there is no branch flow, the metal fine particles and the mist can be blown out from the corresponding outlet.

In addition, it is also possible to release a hair conditioner that imparts a hair care effect to the hair, and to enhance the hair care effect by reducing the amount generated when the hair is relatively dry. As such a hair conditioner, the chemical|medical agent containing an oil component is mentioned, for example. Among the medicines containing oil components, there is a medicine that enhances the hair care effect by attaching a small amount to the surface of the hair.

In addition, it is also possible to include an ambient temperature detection unit that detects an ambient temperature (outside air temperature: room temperature, air temperature, etc. of the user's place) and corresponds to the ambient temperature detected by the ambient temperature detection unit , to change the energization amount or energization time to the heating part.

In addition, the supply amount or supply time of the charged fine particles may be changed according to the hair texture (thickness, length, etc.) of the user.

In addition, the specifications (shape, size, layout, etc.) of the cover, the casing, or other details can be appropriately changed.

Since the heating and blowing device of the present disclosure can obtain the hair temperature required for the care in a relatively short time, it can be applied to, for example, a hair dryer for pets and the like in addition to a hair dryer for humans.
