[0028] Hereinafter, embodiments of the brush 1 involved in this disclosure will be described with reference to the accompanying drawings. This disclosure is not limited to the contents described in the following embodiments, and appropriate design changes can be made within the scope of the structure of this disclosure. In the drawings, the same or equivalent elements are labeled with the same reference numerals, and repeated descriptions are omitted. Only the main parts are shown in the drawings. The following description focuses on the main parts and the parts related to this disclosure.

[0029] In this specification, when indicating the orientation of the brush part 20 and the housing 10 on which the brush part 20 is mounted, the front end side of the bristles 210 protruding in the direction of protrusion is designated as the upper (Z1), and the opposite side is designated as the lower (Z2). The direction perpendicular to the protruding direction Z of the bristles 210 (also referred to as the vertical direction Z) is designated as the horizontal direction X. The direction perpendicular to the vertical direction Z and orthogonal to the horizontal direction X is designated as the front-back direction Y. When indicating the orientation of the cover 30, in the closed state where the cover 30 houses the brush part 20, the front end side of the bristles 210 protruding in the direction of protrusion is designated as the upper (Z1), and the opposite side is designated as the lower (Z2). Furthermore, upper and lower are also referred to as the upper side and the lower side, respectively. In the figures, when viewed from above (a top view from Z1), upper is Y1, and the right side is X2.

[0030] Additionally, in this specification, "parallel" means that the angle (absolute value) between two lines or planes is within the range of 0° ± 3°. Furthermore, "orthogonal" (and "perpendicular") means that the angle (absolute value) between two lines or planes is within the range of 90° ± 3°.

Figure 9 This is a top view that briefly shows the brush section 20.

[0032] like Figure 1As shown, the brush 1 of this embodiment includes a housing 10 and a brush portion 20. In this embodiment, an example is shown where the housing 10 and the brush portion 20 are independent components that are detachably connected (see [reference]). Figure 5 and Figure 8 However, the housing 10 and the brush part 20 can also be integrally formed.

[0033] The housing 10 is a component capable of housing various structures such as electrical components. In this embodiment, the case where the charged particle generating unit 130 is used as an electrical component will be described. When a user combs their hair, the hairbrush 1 equipped with the charged particle generating unit 130 can impart charged particles to the hair, thereby eliminating static electricity or untangling knots, thus facilitating the user to style (set) their hair.

[0034] Charged particles refer to non-electrically neutral particles or active species activated in a non-electrically neutral state. Charged particles are not limited to particles with a charge; for example, they also include particles such as atoms or molecules that, although uncharged, possess unpaired electrons. Specifically, charged particles include, for example, positively charged ions (called positive ions), negatively charged ions (called negative ions), complexes of positive ions, complexes of negative ions, free radicals, electrons, and protons. Preferably, the charged particles are at least one of positive ions or their complexes, and negative ions or their complexes. The charged particle generating unit 130 can be a device for generating one type of charged particle or a device for generating multiple types of charged particles.

[0035] The charged particle generating unit 130 includes charged particle generating electrodes for generating charged particles. The charged particle generating unit 130 may have one or more charged particle generating electrodes; for example, the charged particle generating unit 130 preferably includes a first charged particle generating electrode 111 for generating positive ions or their complexes and a second charged particle generating electrode 112 for generating negative ions or their complexes (see reference). Figure 3 (etc.). Compared to emitting only positive or negative ions, the charged particle generating unit 130 emits negative ions or negative ion complexes and positive ions or positive ion complexes, which can moisturize the hair. Furthermore, the first charged particle generating electrode 111 can be an electrode that generates negative ions or their complexes, and the second charged particle generating electrode 112 can be an electrode that generates negative ions or their complexes. In this specification, unless otherwise specified, the first charged particle generating electrode 111 and the second charged particle generating electrode 112 are simply referred to as charged particle generating electrodes.

[0036] The charged particle generating unit 130 includes, for example, a transformer drive circuit substrate (not shown), a high-voltage transformer (not shown) driven by a high-voltage transformer drive circuit to boost the input voltage, and a substrate 113 having first and second charged particle generating electrodes 111 and 112 for generating charged particles. The transformer drive circuit substrate is a drive circuit substrate that drives the high-voltage transformer with an external input voltage. The high-voltage transformer (high-voltage circuit) is a circuit driven by a high-voltage transformer drive circuit to boost the input voltage. The first and second charged particle generating electrodes 111 and 112 are disposed on the substrate 113, along with dielectric electrodes (not shown) for forming an electric field between the first and second charged particle generating electrodes 111 and 112. The dielectric electrodes are formed in a ring around the respective mounting positions of the first and second charged particle generating electrodes 111 and 112, and are at ground potential. Charged particles are generated by applying the voltage boosted by the high-voltage transformer to the first and second charged particle generating electrodes 111 and 112.

[0037] The charged particle generating electrode can be needle-shaped (see reference). Figure 3 Alternatively, it can be a brush-shaped electrode formed from multiple linear conductors. The charged particle generating electrode is formed of conductive materials such as metal, carbon fiber, conductive fiber, and conductive resin. The charged particle generating electrode is disposed perpendicularly to the surface of the substrate 113 and protrudes from the surface of the housing 10 toward the brush surface 201. The brush portion 20 is provided with an opening 23 for exposing the first and second charged particle generating electrodes 111 and 112 toward the user side.

[0038] The tip of the charged particle generating electrode is located above the brush surface 201. In the hairbrush described in Patent Document 1, the needle electrode for generating ions is positioned lower than the brush surface 201, making it difficult to deliver a large number of ions to the hair. On the other hand, in the hairbrush 1 of this embodiment, since the tip of the charged particle generating electrode is located above the brush surface 201, a large number of charged particles, including ions, can be delivered to the hair. Delivering a large number of charged particles to the hair can suppress the generation of static electricity when the user combs their hair. When the charged particle generating electrode is needle-shaped, the tip of the needle only needs to be located above the brush surface 201; when the charged particle generating electrode is brush-shaped, the uppermost linear conductor only needs to be located above the brush surface 201.

[0039] When the charged particle generating unit 130 has a first charged particle generating electrode 111 and a second charged particle generating electrode 112, it is preferable that the front end of at least one electrode is located above the brush surface 201, and more preferably that the front ends of both the first charged particle generating electrode 111 and the second charged particle generating electrode 112 are located above the brush surface 201.

[0040] The tip of the charged particle generating electrode is preferably located below the tips of the multiple bristles. This prevents the charged particle generating electrode from contacting hair or other parts of the human body. More preferably, with the multiple bristles bent, the tip of the charged particle generating electrode is located below the tip of the lowest bristle among the multiple bristles. This also prevents the charged particle generating electrode from contacting hair or other parts of the human body during use.

[0041] When the charged particle generating unit 130 is provided with a first charged particle generating electrode 111 and a second charged particle generating electrode 112, it is preferable that the front end of at least one electrode is located below the front end of the plurality of bristles, more preferably that, in the state where the plurality of bristles are bent, it is located below the front end of the lowest bristle among the plurality of bristles, but more preferably that the front ends of both electrodes are located below the front end of the plurality of bristles, and particularly preferably that, in the state where the plurality of bristles are bent, it is located below the front end of the lowest bristle among the plurality of bristles.

[0042] The brush section 20 may also contain two or more types of bristles of different lengths. Containing bristles of different lengths makes it easier to untangle hairs. When containing bristles of different lengths, the tip of the charged particle generating electrode is preferably located below the tip of the shortest bristle.

[0043] When the charged particle generating unit 130 has a first charged particle generating electrode 111 and a second charged particle generating electrode 112, it is preferable that the front end of at least one electrode is located below the front end of the shortest bristle, and more preferably that the front ends of both electrodes are located below the front end of the shortest bristle.

[0044] To protect the scalp from the charged particle generating electrode, the hairbrush 1 preferably also includes a peripheral wall 120, which surrounds the charged particle generating electrode and is located above the brush surface 201. The tip of the charged particle generating electrode is more preferably located below the upper end of the peripheral wall 120. In this embodiment, the peripheral wall 120 is shown as being provided on the housing 10 and protruding from the opening 23 provided in the brush portion 20, but the peripheral wall 120 may also be provided on the brush portion 20.

[0045] When the charged particle generating unit 130 includes a first charged particle generating electrode 111 and a second charged particle generating electrode 112, it is preferable to surround at least one electrode, and more preferably, it surrounds two electrodes. In addition, it is preferable that the front end of at least one electrode is located below the upper end of the surrounding wall 120, and more preferably, the front ends of both electrodes are located below the upper end of the surrounding wall 120.

[0046] Although not shown, the side of the surrounding wall 120 may have through holes. When a user combs hair, charged particles such as ions pass through these through holes along with the air, allowing the charged particles to be distributed over a wider area. There are no particular limitations on the number and arrangement of the through holes; for example, more than one horizontal through hole can be provided.

[0047] The brush 1 may have a sealing member 240 disposed around the charged particle generating electrode. By disposing of the sealing member 240 around the charged particle generating electrode, dust and the like can be prevented from entering the housing from the outside. Examples of sealing members include annular rubber gaskets. Since charged particles are generated from the front end of the charged particle generating electrode, in order not to obstruct the generation of charged particles, the sealing member 240 is preferably disposed below the charged particle generating electrode; specifically, it is preferably disposed below the brush surface 201.

[0048] When the charged particle generating unit 130 includes a first charged particle generating electrode 111 and a second charged particle generating electrode 112, the sealing member 240 is preferably disposed around at least one of the first charged particle generating electrode 111 and the second charged particle generating electrode 112, and more preferably disposed around the first charged particle generating electrode 111 and the second charged particle generating electrode 112.

[0049] The housing 10, as an electrical component, may include, for example, a blower fan (not shown) that directs airflow to the brush section 20, an electric heater (not shown), etc. In this embodiment, the hairbrush 1 has its charged particle generating electrode positioned above the brush surface 201, allowing charged particles to be delivered to the hair even without a blower fan. However, by simultaneously generating charged particles and delivering airflow through the blower fan, the charged particles can be delivered to a wider area. The airflow generated by the blower fan is released towards the user side, for example, through the opening 23 and the through-hole provided in the brush section.

[0050] The brush 1, which includes electrical components, is also provided with a control unit for controlling the electrical components and a power supply unit 140 for supplying power to the electrical components. The control unit and the power supply unit 140 are, for example, disposed on the housing 10. The control unit includes a substrate 113. In the accompanying drawings, the power supply unit 140 is shown to include a battery and a power circuit, but the brush 1, as the power supply unit 140, may also include a rechargeable battery and a battery charging terminal (such as a USB female connector) that can be electrically connected to an external charging power supply terminal.

[0051] The housing 10 preferably includes a power switch 170 that switches the energizing path of the charged particle generating unit 130 to an on or off state. Figure 4In this example, the power switch unit 170 includes a button 171 and a physical switch 172 (e.g., a tactile switch) that is linked to the operation of the button 171. When the user presses the button 171, the button 171 moves towards the tactile switch 172, which is then pressed, turning on the power supply path for electrical components such as the charged particle generator 130. The control unit performs the following control: when the device is in the on state, it starts driving the charged particle generator 130; when the device is in the off state, it stops driving the charged particle generator 130.

[0052] The brush 1 may include an illumination 173 (e.g., LED lighting), which illuminates when the power path of the electrical components is switched on and turns off when switched off. When the brush 1 includes the illumination 173, the user can easily identify whether the state is on or off.

[0053] The housing 10 is provided with, for example, a removal switch 174 for mounting or removing the brush 20 from the housing 10, a locking part 175 for locking the brush mounted on the housing 10, and a force-applying member 176 for applying force to the brush 20 upward toward the housing 10 (see reference). Figure 5 and Figure 7 (etc.). The release switch 174 is, for example, a slide switch, which is normally applied to fix the brush part 20 to the housing 10 (locked state). When the user slides the release switch 174, the locked state is released, and the brush part 20 is removed from the housing 10. The force-applying component 176 is, for example, composed of a coil spring and a pressing component.

[0054] When viewed from above, the shell 10 is a rounded quadrilateral. When viewed from above, the shell 10 can be, for example, a rectangle, ellipse, trapezoid, rhombus, semicircle, semi-ellipse, or any combination of various shapes. Furthermore, the shell 10 can be a shape where the area gradually decreases when viewed from above as it approaches the bottom surface 160 (see reference). Figure 6 and Figure 7 The housing 10 may be made of metal or resin, but if the housing 10 or the cover 30 described later is equipped with a magnet, the housing 10 is preferably made of resin.

[0055] The hairbrush 1 can have the handles such as the stick shape found in traditional hairbrushes, but from the perspective of storage and portability, it can also be without handles.

[0056] like Figure 8 As shown, the brush portion 20 has a plurality of bristles 210 protruding from the brush surface 201. More specifically, the brush portion 20 includes a brush surface 201 and a plurality of bristles 210, the brush surface being the surface from which the bristles 210 protrude. The bristles 210 protrude toward a side opposite to the housing 10 (see reference). Figure 1The brush surface 201 is a plane perpendicular to the vertical direction Z. The brush surface 201 preferably has a shape approximately the same as the housing 10 when viewed from above, for example, a rounded quadrilateral when viewed from above. In the brush portion 20, the surface 202 opposite to the brush surface 201 is also referred to as the back side or reverse side of the brush portion 20 (see reference). Figure 3 and Figure 4 The brush portion is positioned such that its back surface 202 is close to or in contact with the housing 10.

[0057] The bristles 210 can be bent, for example, formed of resin material, chemical fiber or animal hair. The brush portion 20 other than the bristles 210 is formed of resin material, for example.

[0058] like Figure 8 and Figure 9 As shown, a plurality of through holes 220 can be provided on the brush portion 20. The brush surface 201 can have a bristle region and an outer edge region. The bristle region has a plurality of bristles 210. When viewed from above, the outer edge region is arranged around the bristle region. The plurality of through holes 220 can be provided in either the bristle region or the outer edge region. When the brush 1 has the conductive fiber body 251 described later, the plurality of through holes 220 are preferably provided in the outer edge region. However, since the through holes 220 are blocked by the conductive fiber body 251, through holes that allow charged particles such as ions to pass through can be provided separately in either the bristle region or the outer edge region. By providing through holes on the brush portion 20, air passes through the charged particle generating unit 130. Charged particles such as ions pass through the through holes along with the air, thus enabling the transfer of charged particles to a wider range.

[0059] The hairbrush 1 has at least a portion of conductive fibers 251 exposed on the brush surface 201. When viewed from above, the conductive fibers 251 are preferably fixed to the brush portion 20 at a position overlapping with at least one of the plurality of through holes 220. In the hairbrush described in Patent Document 2, the conductive material is not sufficiently fixed, and there is a risk that the conductive material may float up or fall off when the user combs their hair. When the conductive material cannot contact the hair, it is sometimes impossible to sufficiently remove (eliminate) the static electricity on the hair. On the other hand, in the hairbrush 1 of this embodiment, since the conductive fibers can be sufficiently fixed on the brush surface 201, the conductive fibers are less likely to float up or fall off, resulting in excellent static elimination. In addition, since the conductive fibers 251 can release the charged static electricity themselves, it is not necessary to ground the body like the hairbrush described in Patent Document 2 to eliminate static electricity, thus allowing for a high degree of design freedom.

[0060] The conductive fiber body 251 is preferably a rope-like component, and more preferably, multiple fibers twisted together. The conductive fiber body 251 is conductive and therefore carries its own charge, enabling it to remove static electricity from static-charged hair. Furthermore, it is believed that the fuzzy surface of the conductive fiber body 251 can effectively release charged static electricity. According to the inventors' research, for example, it is difficult to achieve a sufficient static removal effect with a rope or similar material consisting of multiple twisted metal wires.

[0061] Examples of conductive fibers include iron, chromium, and their alloys (stainless steel), with stainless steel being preferred. Specific examples of conductive fiber bodies include, for example, Naslon (registered trademark) from Nippon Seiki Co., Ltd. Conductive fiber body 251 can be a mixture of stainless steel fibers and natural or chemical fibers, but a twisted rope consisting solely of stainless steel fibers is more preferred. Furthermore, in the case of a mixture, from the viewpoint of minimizing the generation of static electricity, a mixture of stainless steel fibers and natural fibers is preferred. Examples of natural fibers include cotton, silk, hemp, and wool. Examples of chemical fibers include polyester, nylon, acetate fiber, rayon, and cupro fiber.

[0062] The thickness (diameter) of the conductive fiber 251 is preferably 0.1 mm or more and 1.5 mm or less.

[0063] When viewed from above, the method of fixing the conductive fiber 251 to the brush portion 20 at a position overlapping with at least one of the plurality of through holes 220 includes the following variations 1 to 3. By passing the conductive fiber 251 through the through hole 220, or by winding the conductive fiber 251 with other fibers at the position of the through hole 220, the conductive fiber 251 can be fixed to the brush portion 20.

[0064] Figure 10 This is a schematic top view of a modified example 1 illustrating the case where the brush section 20 has conductive fibers. Figure 11 It is magnification Figure 10 A schematic cross-sectional view of a portion. (e.g.) Figure 10 and Figure 11 As shown, the brush surface 201 may include a wide portion d1 with a relatively large distance between two adjacent through holes and a narrow portion d2 with a narrower distance between two adjacent through holes than the wide portion d1. The conductive fiber 251 passes through one of the plurality of through holes 220, namely a first through hole 220a, from the brush surface 201 side of the brush portion 20 to the back surface 202 side, and then passes through a second through hole 220b, different from the first through hole 220a, from the back surface 202 side of the brush portion 20 to the brush surface 201 side, thereby fixing the conductive fiber 251 to the brush portion 20. In other words, at least other portions of the conductive fiber 251 are exposed on the back surface 202 side of the brush portion 20. The conductive fiber 251, for example, can be tied at its starting and ending points to form a loop.

[0065] At least a portion of the conductive fiber 251 is preferably exposed on the brush surface 201 of the wide portion d1. In this way, more of the conductive fiber 251 can be exposed on the brush surface 201, resulting in a high static removal effect.

[0066] In the first embodiment, a case is illustrated where the wide portion d1 and the narrow portion d2 are arranged alternately, but this is not a limitation; the wide portion d1 or the narrow portion d2 may be arranged continuously. Furthermore, the distance between two adjacent through holes may be equal.

[0067] Figure 12 This is a schematic top view of a modified example 2, illustrating the case where the brush section 20 has conductive fibers. Figure 13 It is magnification Figure 12 A schematic cross-sectional view of a portion. (e.g.) Figure 12 and Figure 13 As shown, the brush of Modified Example 2 further includes other fibers 252, at least a portion of which are exposed on the back surface 202 of the brush portion 20. In Modified Example 2, the other fibers 252 pass through a first through hole 220a from the back surface 202 side of the brush portion 20 to the brush surface 201 side, and then pass through a second through hole 220b from the brush surface 201 side to the back surface 202 side. In Modified Example 2, the distance between two adjacent through holes is equidistant, but it is not limited to this; it may have a wide portion d1 and a narrow portion d2 as in Modified Example 1.

[0068] Other fiber bodies 252 may not be conductive fibers; for example, they may be the aforementioned natural fibers or chemical fibers. However, from the viewpoint of minimizing the generation of static electricity in hair, fibers with a charge sequence similar to that of hair, such as natural fibers, are preferred. From the viewpoint of more effectively removing static electricity, other fiber bodies 252 are also preferably conductive fibers.

[0069] Figure 14 This is a schematic top view of a modified example 3, illustrating the case where the brush section 20 has conductive fibers. Figure 15 It is magnification Figure 14 A schematic cross-sectional view of a portion. (e.g.) Figure 14 and Figure 15 As shown, the hairbrush of Modified Example 3 also includes other fibers 252, at least a portion of which are exposed on the back surface 202 of the brush portion 20. The other fibers 252 may be those illustrated in Modified Example 2.

[0070] In Modification 3, the conductive fiber 251 and other fibers 252 intersect each other at a position overlapping one of the multiple through holes 220 when viewed from above. The portion of the conductive fiber 251, excluding its intersection with the other fibers 252, is disposed on the brush surface 201 side of the brush portion 20. Furthermore, the portions of the other fibers 252, excluding their intersection with the conductive fiber 251, are disposed on the back surface 202 side of the brush portion 20. In Modification 3, like sewing with a sewing machine, the upper thread (conductive fiber 251) enters the through hole 220 from the brush surface 201 side, and the lower thread (other fibers 252) enters the through hole 220 from the back surface 202 side. The upper and lower threads are wound within the through hole 220, with the upper thread again exposed on the brush surface 201 and the lower thread exposed on the back surface 202 side. With this configuration, the conductive fiber 251 and other fibers 252 are fixed to the brush portion 20.

[0071] In variation 3, the other fiber body 252 may not be a conductive fiber body, such as the aforementioned natural fiber or chemical fiber, but from the viewpoint of being able to remove static electricity more effectively, the other fiber body 252 is also preferably a conductive fiber body. When the tension of the upper and lower wires is different, the lower wire may sometimes be pulled from the through hole 220 to the brush surface 201 side, so both the upper and lower wires are preferably conductive fibers.

[0072] In Modification Example 3, the distance between two adjacent through holes is equal, but it is not limited to this. It can have a wide portion d1 and a narrow portion d2 as in Modification Example 1.

[0073] Figure 16 It is magnification Figure 3 A three-dimensional view of the part corresponding to the dashed line in the middle, as shown in Example 4. Figure 17 It is magnification Figure 3 A three-dimensional view of the portion corresponding to the dashed line in example 5. Figure 16 As shown, the brush surface 201 of the brush portion 20 may have a first groove 231 disposed between two adjacent through holes 220. The first groove 231, the second groove 232 and / or the third groove 233, described later, are preferably disposed in a region that overlaps with the outer edge region of the brush portion 20 when viewed from above.

[0074] Figure 16 The conductive fiber 251 is not shown in the diagram, but when arranging the conductive fiber 251, the portion of the conductive fiber 251 exposed on the brush surface 201 is preferably arranged along the first groove 231. By arranging the conductive fiber 251 along the first groove 231, it is possible to more effectively prevent the conductive fiber 251 from floating up or falling off the brush surface 201. In addition, it is possible to prevent the conductive fiber 251 from being hooked and damaged during use. The depth of the first groove 231 is preferably deeper than the diameter of the conductive fiber 251, and when the brush surface 201 is viewed horizontally, it is preferable that the conductive fiber 251 does not protrude from the first groove 231.

[0075] like Figure 3 , Figure 8 , Figure 16 , Figure 17 As shown, the brush 1 may also include a back part 21 disposed on the back side 202 side of the brush part 20. Figure 16 The conductive fiber 251 is not shown in the diagram, but when the conductive fiber 251 is arranged, the portion of the conductive fiber 251 exposed on the back surface 202 is preferably arranged between the brush portion 20 and the back surface component 21. For example... Figure 17 As shown, by sandwiching the conductive fiber 251 between the brush portion 20 and the backing material 21, and pressing it in while extruding with the two components, the conductive fiber 251 can be more firmly fixed to the brush portion 20. When viewed from above, after the conductive fiber 251 is fixed to the brush portion 20 at a position overlapping at least one of the plurality of through holes 220, it can be treated as a single unit by, for example, melting the brush portion 20 and the backing material 21.

[0076] Preferably, the back panel 21 has an opening of the same shape as the opening 23 at a position that overlaps with the opening 23 when viewed from above. On the other hand, the back panel 21 may not have multiple through holes 220.

[0077] The back surface 202 of the brush portion 20 may have a second groove 232 disposed between two adjacent through holes 200 (see reference). Figure 3 The portion of the conductive fiber 251 exposed on the back surface 202 is preferably arranged along the second groove 232. Providing grooves on both the brush surface 201 and the back surface 202 of the brush portion 20 makes it more difficult for the conductive fiber 251 to deviate. The depth of the second groove 232 is preferably shallower than the diameter of the conductive fiber 251.

[0078] like Figure 16 As shown, when viewed from above, the back panel 21 may have a third groove 233 on the surface opposite to the brush portion 20. The third groove 233 is configured to overlap with the first groove 231 when viewed from above. From the viewpoint of more firmly securing the conductive fiber 251, the depth of the second groove 232 is preferably shallower than the diameter of the conductive fiber 251, and when the second groove 232 is provided, the third groove 233 is preferably not provided.

[0079] The brush 1 may also have a cover 30. The cover 30 is a separate component from the housing 10 and a separate component from the brush part 20. Figure 18 This is a three-dimensional diagram that briefly represents the closed state of brush 1. Figure 19 This is a 3D diagram that briefly shows the open state of brush 1. Figure 20 yes Figure 19 A cross-sectional view of line A-A' in the middle. Figure 21 yes Figure 19A cross-sectional view along line B-B'. The cover is detachably mounted on the housing 10, allowing the closure state of the brush storage section 20 to be changed (see reference). Figure 18 ) and the open state of the open brush section 20 (refer to Figure 19 The brush bristles 210 are housed within the cover 30, which is positioned between the brush bristles and the outer surface 150 of the housing 10. The cover 30 is installed on the housing 10, and when the brush bristles 210 are housed within the cover 30, the housing is in a closed state. The inner surface 32 of the cover 30 and the outer surface 150 of the housing 10 approach or contact each other. When the cover 30 is removed from the closed state to allow the brush bristles 210 to open, the housing is in an open state (see reference). Figure 20 and Figure 21 ).

[0080] With the front end of the bristles 210 protruding in the upward direction as the top, the cover 30 is detachably mounted on the lower part of the housing 10 in the open state. The user can use the hairbrush 1 while holding the cover 30 mounted on the lower part of the housing 10. This makes it easy for the user to hold the hairbrush 1 and also prevents the cover 30 from being lost.

[0081] Furthermore, the outer surface 31 of the cover 30 preferably has a curved concave portion, which forms a recess on the housing 10 side when the cover is closed (see reference). Figure 18 to 21 Therefore, the user can easily hold the cover 30, thus improving the usability of the hairbrush 1. Additionally, a portion of the outer surface 31 of the cover 30 can be a concave portion, or it can be like... Figure 18 As shown, the outer surface 31 of the cover portion 30 is integrally formed into a concave portion.

[0082] The cover 30 is formed of, for example, a resin material. When viewed from above, the cover 30 is preferably in a shape that is substantially the same as that of the housing 10, for example, a rounded quadrilateral when viewed from above.

[0083] The cover 30 preferably covers the power switch section 170 when closed, and exposes the power switch section 170 when the cover 30 is installed at the bottom of the housing 10. When not in use, the cover 30 is closed to prevent accidental operation; when in use, with the cover 30 installed at the bottom of the housing 10, the user can operate the power switch section 170.

[0084] A magnet 40 may be provided on one of the inner surface of the cover 30 and the outer surface of the housing 10, and a magnetic body 41 may be provided on the other. Figure 20 and Figure 21In this example, a magnetic element 41 is provided on the outer surface of the housing 10, and a magnet 40 is provided on the inner surface of the cover 30. However, it is also possible to provide a magnetic element 41 on the inner surface of the cover 30 and a magnet 40 on the outer surface of the housing 10. When a user moves the cover 30 closer to the housing 10 from the top to achieve a closed state, the magnetic element 41 on the housing 10 and the magnet 40 on the cover 30 will attempt to connect through magnetic force. Therefore, the user can easily achieve a closed state without exerting force.

[0085] Magnet 40 is disposed on the inner side surface 32 of the cover 30. Magnet 40 may be disposed at one or more locations on the inner side surface 32 of the cover 30, or may be disposed along the inner circumference of the inner side surface of the cover 30 for more than half of the entire length of the inner circumference.

[0086] The magnetic element 41 is disposed in the outer surface 150 of the housing 10, and in the closed state, it approaches or contacts the magnet 40 of the cover 30. It is particularly preferred that the magnetic element 41 be disposed along more than half of the outer perimeter of the outer surface 150 of the housing 10. The magnetic element 41 is, for example, a metal plate made of a magnetic metal. Examples of materials for the magnetic element 41 include iron, cobalt, nickel, or alloys thereof (such as stainless steel).

[0087] The housing 10 and the cover 30 may each have a first fitting portion 151 and a second fitting portion 34 that fit together. This securely maintains the closed state, thus further improving usability. Figure 20 and Figure 21 As shown, the outer surface 150 of the housing 10 is formed with ribs along its entire circumference, which is an example of the first fitting portion 151. The first fitting portion 151 may not be provided along the entire circumference of the outer surface 150, but rather on a portion thereof. A portion or the entire circumference of the inner surface 32 of the cover 30 is provided with a second fitting portion 34 that engages with the first fitting portion 151 (see Figure 151). Figure 20 and Figure 21 ).
