[0026] The brush unit 20 has a plurality of pins 50. The plurality of pins 50 are arranged on the brush base 40. Specifically, in this embodiment, each pin 50 is provided in a vertical position from the front surface 40A. 8, the brush base 40 is formed on a front surface 40A thereof with a plurality of tufting holes 41, and the brush base 40 is planted in the tufting holes 41. Each pin 50 is made of a resin wire material such as nylon. Each pin 50 is straight in its natural state. The tip of each pin 50 is The pins 50 are machined into a spherical shape with a diameter larger than that of the linear portion. The arrangement is the same as the arrangement of the tufting holes 41.

[0027] The pin 50 bends the linear material cut to a predetermined length, and the bent portion The fibers are planted in the planting holes 41. A pair of pins 50 is provided for each tufting hole 41. The first pin 51 has a relatively long protruding length from the front surface 40A, and the second pin 52 has a relatively short protruding length. Of the two types of pins 51 and 52 having different lengths, the pin 51 according to the present invention An example of the pin is the first pin 51. The protruding length of each first pin 51 is set to the same length. The protruding lengths of the second pins 52 are also the same. The protruding length of the first pin 51 is about 0.8 times the protruding length of the first pin 51. The protruding length of the first pin 51 from the front surface 40A is 21 mm, and the protruding length of the second pin 52 from the front surface 40A is 21 mm. The protruding length from 40A is 16 mm. As the pin, the first pin 51 is connected to the second pin 52. If other pins are provided, they may be of only one length. The other pins may be of three or more types, and may be arranged in the same implantation holes as the pins according to the present invention. The tufting holes may be erected from the same tufting hole, or may be erected independently from different tufting holes.

[0028] As shown in FIG. 9, in the brush unit 20, an imaginary plane connecting the tips of the plurality of first pins 51 is formed. V is recessed toward the front surface 40A of the brush base 40. In other words, the imaginary surface V is The imaginary plane V is formed in a concave shape toward the base end side of the first pin 51. In this embodiment, the imaginary plane V is The surface is similar to the curved surface of the front surface 40A of the brush base 40. This is because they are erected at the same length from the front surface 40A of the base 40. The bush-shaped surface M is represented by connecting the tips of adjacent first pins 51 with a straight line. The virtual surface V can be approximately expressed as a mesh-like surface M. The virtual surface V is The brush head 20 is recessed most toward the brush base 40 (rear side) at the center of the brush head 20. The brush base 40 is gradually raised toward the periphery of the brush head 20. Such a virtual surface V has a continuous concave and convex shape without any local concave and convex portions. The tip of the second pin 52 is located closer to the brush base than the imaginary plane V. It is located on the S40 side (rear).

[0029] As shown in FIG. 10, the brush part 20 has a non-contact part 21 and a contact part 22. The contact portion 21 is a portion where the tip of the pin 50 does not come into contact with the scalp when in use. The contact portion 22 is the portion where the tip of the pin 50 comes into contact with the scalp when in use. The brush head 20 is provided on both sides of the non-contact portion 21. The usage state is when the front of the brush head 20 is applied to the scalp. In this embodiment, the non-contact portion 21 is in contact with the brush portion 20. The contact portion 22 corresponds to the portion where the pin 50 is not erected in the brush portion 20. The non-contact portion 21 corresponds to the portion where the pin 50 is erected. In this embodiment, the contact portion 22 is provided around the entire periphery of the non-contact portion 21. It is being done.

[0030] The brush head 20 has a plurality of regions that have different hardnesses to feel. The area is an area where a plurality of pins 50 are erected in the brush head 20. The phrase "is different" refers to the resistance received from each pin in contact with the scalp when the brush part 20 is placed against the scalp. As shown in FIG. 10, the brush part 20 has a plurality of regions. The inner region R1 and the outer region R2 are Each of these is a part of the area that constitutes the contact portion 22.

[0031] As shown in FIG. 10, the inner region R1 is disposed in the center of the brush head 20 in the left-right direction. The inner region R1 is a region where the perceived hardness is softer than the outer region R2. The inner region R1 is a vertically long region in which three rows of pins 50 are erected in the center of the left-right direction. The inner region R1 is disposed on the outer side in the up-down direction with the non-contact portion 21 sandwiched therebetween.

[0032] The outer region R2 is located outside (closer to the outer edge) than the inner region R1. The region R2 is disposed adjacent to the outer side of the inner region R1 in the left-right direction of the brush part 20. The outer region R2 is a region that feels harder to the touch than the inner region R1. In the case of the embodiment, the difference between the tactile sensation received from the inner region R1 and the tactile sensation received from the outer region R2 is This is created by making the thickness and material of the pins 50 erected in the regions R1 and R2 different. Specifically, the pins 50 in the inner region R1 have a thickness of the linear material used that is smaller than that of the outer region R2. The pins in the inner region R1 are thinner than the pins 50 in the inner region R2. The pins 50 in the outer region R2 are softer due to the inclusion of the metal.

[0033] The operation of the hair brush 1 having the above configuration will be explained together with how to use it. The method of using the hair brush 1 for washing hair will be described.

[0034] First, gently brush your scalp and hair. This brushing should be done before wetting your hair. When performing such brushing, as shown in FIG. The handle 32 is located at a position below and away from the brush head 20. Therefore, when brushing by gripping the handle 32, the user can easily use a snap of the hand. It is suitable for brushing a wide range of areas. In addition, the handle 32 is curved so that it is convex outward. Its shape allows it to be wrapped around the palm of your hand and held firmly. Furthermore, when the handle 32 is wrapped around the palm of the hand, the thumb and index finger are placed on the constricted portions 33 and 34. Therefore, the hairbrush 1 can be held more firmly.

[0035] Next, wet the scalp and hair, lather up a detergent such as shampoo, and apply it. Brush so that the oil reaches the entire scalp. As shown in FIG. 12, place your thumb, index finger, and middle finger on the left and right notches 31B. It is advisable to hold the handle body 31. The handle body 31 is located behind the brush unit 20. Therefore, when brushing by gripping the handle body 31, the brush part 20 is pressed against the scalp. The cutout portion 31B is formed by cutting the side surface of the handle body 31. Because it is formed with a notch, it is easy for fingers to get caught even with wet hands that have detergent on them. As a result, slippage can be suppressed and the handle body 31 can be firmly gripped. When the handle body 31 is gripped by hooking the index finger and middle finger into the notch portion 31B At least one of the ring finger and the little finger can be placed in the constricted portions 33 and 34. The hair brush 1 can be more firmly gripped. The gripping portions 33 and 34 are provided symmetrically, so that the gripping portion 33 can be held in the same way regardless of whether it is held with the right or left hand. It is possible.

[0036] In the hairbrush 1, the brush part 20 has an imaginary surface connecting the tips of the plurality of first pins 51. V is recessed toward the front surface 40A of the brush base 40, which is the surface of the main body. The tip of each first pin 51 in the brush portion 20 can be easily brought into close contact with the scalp.

[0037] The brush part 20 has a non-contact part 21 and contact parts 22 on both sides of the non-contact part 21. By having the above-mentioned structure, the first pins 51 in the contact portions 22 on both sides of the non-contact portion 21 can be securely attached to the scalp. As shown in FIG. 13, when the brush part 20 is placed facing the scalp, The pins 50 at the contact portions 22 on both sides of the contact portion 21 are arranged obliquely with respect to the curved surface of the scalp. The first pin 51 that has come into contact with the scalp is pushed further against the scalp, and is then pushed out. This allows the outer first pins 51 to come into contact with the scalp. As a result, many pins in the contact portion 22 can be brought into contact with the scalp.

[0038] In contrast to this, for example, as shown in FIG. 14, if a pin P similar to the first pin 51 is In other words, the brush part B shown in FIG. In this case, the pin P that first contacts the scalp is normal to the scalp. Pins P that come into contact in the normal direction tend to be pushed against the scalp, The other pins P arranged outside of this pin P are less likely to come into contact with the scalp.

[0039] In comparison with the brush part B, the brush part 20 according to this embodiment has a non-contact part 21. By having such a structure, the brush section 20 as a whole has excellent adhesion to the scalp. The portion 20 is oriented such that the imaginary plane V connecting the tips of the first pins 51 faces the front surface 40A of the brush base 40. Therefore, the tip of each first pin 51 is recessed, so that the tip of each first pin 51 is more firmly attached to the scalp. The brushing can be done with the ends in closer contact with the scalp, which has a cleansing effect on the scalp. The brush part 20 is shorter than the first pin 51. Since the second pins 52 are provided, the tips of more pins 50 can be brought into contact with the scalp. It has particularly excellent adhesion to the scalp.

[0040] When brushing with the hair brush 1, the outer region R2 and the inner region R3 of the brush part 20 are It is recommended to brush in the direction in which the area R1 passes sequentially, i.e., in the left-right direction. In the embodiment, the outer region R2 is a region having a softer feel of hardness than the inner region R2. The brush head 20 is positioned on the outside of the left and right sides of the area R1. When lashing is performed, the outer area R2 on either the left or right side passes through first. Pin 50 in R2 penetrates into the gaps in the hair that covers the scalp and lifts it up. The next pin 50 in the inner region R1 passes through the tangled hair lifted from the scalp. Then, in the outer region R2 that is the last to pass through, each pin 50 has a raised head. The pins 50 can be attached to the scalp through the gaps in the hair. By improving the adhesion of the scalp, it is possible to effectively scrape off dirt adhering to the scalp surface and It is possible to suitably impart a massage effect.

[0041] In addition, the tip of each pin 50 is rounded, so that when washing hair, any hair that has adhered to the scalp is easily removed. It can pick up and scrape away dirt, and when massaging, the tip becomes spherical. A larger area comes into contact with the scalp compared to untreated, providing a wider coverage The tip of each pin 50 is spherical, so that it can provide a surge effect. Therefore, even when the side portions of the tip ends of the pins 50 are in contact with each other, the dirt scraping action is still possible. In other words, if the tip of the pin is spherical, the spherical part On either side, a surface opposite to the brushing direction is created, allowing dirt to be scraped off. do.

[0042] The hair brush 1 also includes an ion plate 60. The action of ions generated from the ionizer 60 can be applied to the scalp and hair. For example, sebum Dirt has a negative potential, so the scalp with sebum dirt has a positive potential, The on-balance state is disturbed. In this case, they are attracted by each other's potential, The bond between sebum and the scalp is strengthened. Ion plates are designed for such scalps. By releasing ions from the 60, it helps to balance the ions and eliminates the bond between sebum and the scalp. It is expected to reduce stickiness and create an environment that makes it easier to remove dirt.

[0043] After using the hair brush 1, store it in the stand S (see Figure 1). By storing the hair brush 1 in an upright position, it is possible to drain the water properly after washing the hair. In addition, the stand S allows you to store the hair brush 1 upright. Therefore, deformation of each pin 50 in the brush part 20 can be suppressed.

[0044] As described above, the hair brush 1 according to the first embodiment includes the main body 10 and the brush part 20. The brush unit 20 has a plurality of first pins 51. 1 is erected from the front surface 40A of the brush base 40, which is the surface of the main body. An imaginary plane V connecting the tips of the blades 51 is recessed toward the front surface 40 A of the brush base 40 . The brush part 20 has a non-contact part 21 and a contact part 22. The non-contact part 21 is The contact portion 22 is a portion where the tip of the first pin 51 does not come into contact with the scalp. 0, the tip of the first pin 51 in the use state. This is the part that touches the scalp.

[0045] Therefore, the hair brush 1 has the first pins 51 in the contact portions 22 on both sides of the non-contact portion 21. The first pins 51 on both sides of the non-contact portion 21 can be securely attached to the scalp. In this case, the head is likely to come into contact with the curved surface of the scalp in an oblique direction (a direction other than the normal direction). The first pins 51 that come into contact with the scalp are easily pushed further against the scalp and fall outward. As a result, many pins in the contact area can be brought into contact with the scalp. The hair brush 1 can improve the degree of contact with the scalp. The pin 51 comes into contact with the scalp not only at the tip but also at the side of the tip. This allows a larger area to come into contact with the scalp, further improving adhesion to the scalp. do.

[0046] In addition, in the hair brush 1, the contact portion 22 is provided around the non-contact portion 21. This allows you to brush without any restrictions on direction, and allows you to brush freely. The degree can be increased.

[0047] In addition, in the hair brush 1, the brush part 20 has a plurality of regions, an inner region R1 and The inner region R1 and the outer region R2 are provided with a plurality of first pins. 51 are erected, and the tactile sensation of the received hardness is different. This allows for different brushing effects.

[0048] In addition, in the hair brush 1, the inner region R1 and the outer region R2 are The outer region R2 is located outside the side region R1, and the feel of the outer region R2 is harder than that of the inner region R1. Therefore, the first pins 51 lift up the hair in the outer region R2, and In this case, the tangled hair in the outer region R2 is untangled, and further in the outer region R2, The first pins 51 come into strong contact with the scalp at the roots of the raised hair, providing a cleaning and massaging effect. It is possible to effectively provide different brushing actions in each area R1 and R2, such as providing can.

[0049] <Example 2> Next, a hair brush according to Example 2 will be described. As shown in FIG. 15, the outer region R2 of the brush part 220 is provided around the inner region R1. The other configurations are the same as those of the first embodiment, and the same configuration is used. The components are given the same reference numerals and detailed explanations will be omitted.

[0050] A hair brush equipped with such a brush part 220 can be used without any restriction on direction, regardless of the hardness of the brush. It is possible to brush while exerting the effect of each area with a different tactile sensation. In the case of the configuration of Example 1, when brushing in the up and down direction, the inner region R1 and the outer region R2 In contrast, the brush part 220 has a portion where only one of the outer regions is in contact. Since R2 is provided around the entire periphery of the inner region R1, brushing in any direction Even in the case of a directional beam, it can pass through both the inner region R1 and the outer region R2. It is possible to give different brushing actions to the regions R1 and R2 without any restrictions on the quality of the brushing. do.

[0051] The present invention is not limited to the embodiments described above and illustrated in the drawings. For example, the following embodiments are also included within the technical scope of the present invention. (1) In Examples 1 and 2, the contact portion is provided around the non-contact portion. The contact part is provided on the outside of the non-contact part in one direction, such as the outside in the left-right direction or the outside in the up-down direction. It may also be used. (2) In Examples 1 and 2, the pin is not provided in the non-contact portion. The non-contact portion may have a pin that is shorter than the length of the pin in the contact portion, for example. The tip of the pin is closer to the surface of the main body than the tip of the pin closest to the surface of the main body at the contact point. In this case, the pin of the non-contact portion may be positioned on the side of the brush portion. When contacting the scalp, the pin at the contact part is pressed further after the tip of the pin contacts the scalp. When the tip of the device is tilted outward and the side of the tip comes into contact with the scalp, That is, if a pin is provided in the non-contact portion, the pin may be It is preferable that the side of the tip of the pin at the contact portion does not hinder contact with the scalp. In this case, the pin provided in the non-contact portion is preferably, for example, a pin in the contact portion having a tip. After contacting the scalp, the tip is pressed further and tilted outward, so that the side of the tip comes into contact with the scalp. The non-contact portion can be configured not to come into contact with the scalp until the scalp is fully exposed. The tip position of the pin is determined by, for example, using the pin closest to the surface of the main body at the contact point as the reference pin. When this is done, the reference pin is located at a position 0.5 times or more away from the tip of the reference pin. It can be placed. (3) In Examples 1 and 2, multiple pins are erected, and multiple regions with different tactile hardness are provided. Although the brush part has been illustrated as having a hardness of 0.05, this is not required. The shape may have only one area where the tactile sensations of hardness are the same. When there are multiple regions, the number may be three or more. (4) In Examples 1 and 2, the main body has a handle and a brush base. However, this is not essential. The main body has the handle and brush base already attached. The main body may be formed as a body. It is not essential that the main body has a grip portion. When the gripping portion has a gripping portion, the shape of the gripping portion is not limited to a curved shape. There is no particular requirement for the shape as long as it is easy to hold. (5) In Examples 1 and 2, the pins are implanted into implant holes in the main body. However, this is not essential. The pin is not limited to one implanted in the main body, but may be one integrally formed with the main body. It may also be something that has been (6) In the first and second embodiments, when the imaginary surface V is formed in a concave shape, the surface of the main body The front surface 40A of the brush base 40 is formed in a concave shape, and the first pin as a plurality of pins 51 is erected at the same length from the front surface 40A of the brush base 40. It is not essential. To form the imaginary surface V in a concave shape, the lengths of the pins may be made different. In this case, the surface of the main body is not formed to be concave, but a virtual concave surface is formed. That is, the "surface of the main body" according to the present invention may be a flat surface, The projection may be formed in a convex shape in the direction in which the pin projects. (7) In Examples 1 and 2, the thickness and hardness of the pins are varied to provide different tactile sensations. Although the example shows a form in which the material is different for each area, this is not essential. In addition to the thickness and material of the pins, the shape of the pins per unit area can also be changed. The number of pins and the length of the pins may be different for each area, or two or more of these may be combined. Also, for example, like the second pin exemplified in each of the above embodiments, In the present invention, other pins having a shorter protruding length from the surface of the main body than the plurality of pins may be provided. In this case, for example, the present invention By changing the difference between the protruding length of the pin and the protruding length of the other pin, The hardness of the texture can be easily adjusted. (8) Providing other pins with shorter protruding lengths from the surface of the main body than the plurality of pins according to the present invention In this case, the protruding length is, for example, 0.7 to 0 times the protruding length of the plurality of pins according to the present invention. Within this range, the first pin can be brought into contact with the scalp and knocked down. When the second pin is attached, it can easily contact the scalp, making it easy to improve adhesion to the scalp. It can be achieved. (9) In the first and second embodiments, the brush base constituting the surface of the main body of the present invention has a through hole. The ion plate is disposed behind the ion plate. In terms of form, this is not essential. When an ion plate is arranged, for example, Alternatively, the surface of the part may be recessed to form a recess, and the part may be disposed in the recess. For example, the ion plate may be disposed directly on the surface of the main body. Instead of or in addition to the above, substances that contribute to ion generation may be directly included in the materials that make up the main body and pins. It may be allowed to have. (10) The hair brush according to the present invention may have other functions instead of the ion plate. Other functional components may include, for example, a component having an acupressure function. Examples include protruding functional components and functional components that have a function of improving the design of logos, etc. In the case where functional components are provided, these ion generating function, acupressure function, and design improving function are The functional member may have two or more different functions, such as a function for heating or cooling.

[0052] An experiment was conducted to demonstrate the effectiveness of the hair brush of the present invention. A cleaning experiment was carried out. The experiment was carried out using a hair brush according to the present invention, which had the same structure as that of Example 1. As a comparative example, a hair brush was used to wash the scalp by hand. In each experiment, a mixture of sebum and impurities was applied to the test area of ​​the scalp in advance. Each method was used for one minute of washing, and the condition of the scalp was observed using a microscope. The results are shown in Figure 16.

[0053] As shown in FIG. 16, (A) shows the state before washing, and the state where the artificial soil is attached to the scalp. In the comparative example (B), which shows the state after hand washing, the pseudo-soil has been removed to some extent. The defects are clearly visible, but there are areas that have not been washed, such as the areas indicated by the circles and arrows. In (B), the pseudo-soil that was not washed away is present at the base of the hair on the scalp (near the pores). In this regard, when washing your hands, your fingertips may not be able to touch the scalp at the base of your hair. I think this shows that.

[0054] In contrast, in (C) which shows the state after washing using the hair brush of the present invention, the scalp No artificial soil was found to adhere to the hair, including the base of the hair. This is because the pins were not attached to the scalp. This is thought to be because the artificial dirt adhered to the scalp is scraped off by the appropriate contact. It is believed that the hair brush according to the present invention allows the tips of the pins to come into good contact with the scalp.

[0055] A sensory evaluation was carried out on the feel of using the hair brush according to the present invention. After washing hair using a hair brush with the same structure as in Example 1, (1) a refreshing feeling on the scalp, (2) hair (3) Hair manageability, and (4) Hair smoothness were each rated on a three-point scale. The study was conducted on 48 subjects who used the brush for one week. The results are shown in Figure 17. The hair brush of the present invention has a performance of 80% or more in any of the items (1) to (3). The subjects were able to feel the effects, especially (1) a refreshing feeling on the scalp and (2) improved manageability of hair. In this case, more than 90% of subjects felt the effects.
