[MODE FOR CARRYING OUT THE INVENTION]

[0012] First, embodiments of the present invention will be listed and described. Any combination of the following embodiments within a scope that does not cause contradiction is also included in the mode for carrying out the invention.

[0013] [1] A hairbrush according to an embodiment of the present invention comprises: a base portion; and extending from a front surface of the base portion The base portion comprises multiple upright pins and forms a ventilation passage that penetrates from the rear to the front. As a result, the size of the opening at the rear end of the ventilation passage is larger than the size of the opening at the front end. The brush has a larger opening at the rear end of the air passage that penetrates the base than at the front end. Therefore, this hairbrush has a rear opening that is the same size as the front opening, compared to a case where the opening at the rear end is the same size as the front end. It is easy to draw air into the ventilation channel through the opening at the end. Also, this hairbrush is in the ventilation channel Because the opening at the front end is smaller than the opening at the rear end, ventilation occurs at a faster flow velocity than the inflow velocity. It's possible to make wind blow out from the road. [2] Another embodiment of the present invention is a hairbrush comprising a base portion and the front surface of the base portion. It comprises multiple pins erected from the base, and the base portion has a ventilation passage that penetrates from the rear to the front. The rear end of the wall surface of the base portion that forms the ventilation passage is located outside the base portion. The center side is located further back. This hairbrush has a wall on the base that forms a ventilation channel. In this configuration, the wall located closer to the center is positioned further back than the wall located on the outside of the base. For example, when blowing air from a hairdryer from the outside of the base towards the center, And the airflow can be received by the wall on the central side. Therefore, this The brush is such that the rear end position of the wall surface of the base portion that forms the ventilation passage is the same inside and outside the base portion. Compared to the other configuration, it is easier to draw air into the ventilation passage through the opening at the rear end. Also, with this configuration Regardless of which direction the hairdryer's airflow is directed from the outside of the base, the center of the base It can be received by the side wall and introduced into the ventilation channel. [3] In either of the hairbrushes described in [1] and [2] above, the ventilation passage is formed The length of the wall surface of the base portion in the front-to-back direction is longer on the central side than on the outer side of the base portion. This hairbrush is different from one where the front-to-back length of the base wall forming the air passage is uniform. The front opening of the ventilation channel, formed by a wall surface with a longer front-to-back length, is positioned closer to the scalp. It can be positioned. Therefore, this hairbrush is positioned perpendicular to the front-to-back direction of the hairbrush. Near the center, air can be directed closer to the scalp. For example, by forming an air passage. The rear end of the wall surface of the base portion is located further back towards the center than the outer side of the base portion. [2 In combination with the configuration of ], the length of the wall on the central side of the base is made longer than the outer side, The configuration brings the front end of the wall on the front center side closer to the front end of the outer wall. By adopting this design, it is possible to equalize the distance between the opening at the front end and the scalp. [4] In any of the hairbrushes described in [1] to [3] above, the ventilation passage is formed Of the wall surfaces of the base portion, the rear end of the wall surface on the central side faces outward from the base portion. It is sloped. This hairbrush, for example, brushes from the outside of the hairbrush towards the center. When applying airflow to the ear, the central wall surface that receives the airflow will affect the airflow. This can guide the vehicle so that it is moving forward. [5] In any of the hairbrushes described in [1] to [4] above, the ventilation passage is formed The wall surface of the base portion has ridge-like undulations that extend in the front-to-back direction. The brush guides and straightens the airflow through the ventilation channel into a forward-backward flow due to its undulating surface. Therefore, this hairbrush efficiently directs the air introduced into the vent forward. It is possible.

[0014] Further embodiments of the present invention will be listed and described. Therefore, one of the following embodiments is used in relation to one of the above embodiments. This also includes combinations that do not create a shield. [6] A hairbrush according to yet another embodiment of the present invention comprises a base portion and the base portion The base portion comprises a first base portion and a plurality of pins erected from the front, and the base portion comprises a first base portion and the front-rear direction In contrast, a second base portion surrounds the first base portion in the circumferential direction in an intersecting direction, and the first It has an elastically deformable connecting part that connects the base part and the second base part. In a hairbrush, a space is formed between the first base portion and the second base portion of the base. Therefore, this hairbrush is designed to allow the hairdryer's airflow to reach behind the brush, for example, when brushing. By allowing air to circulate from the side to the front through this space, ventilation can be ensured between the front and back sides. This can be done. Also, the connecting part between the first base and the second base of this hairbrush is elastic. It is freely deformable. For this reason, the first base part and the second base part are each independently separated by the connecting part. It can stand upright and move. As a result, this hairbrush has pins that stand upright from the first base. The pins erected from the second base section can be easily brought into contact with the scalp. This can improve the fit. [7] In the hairbrush described in [6] above, the first base portion is a through-hole that penetrates in the front-to-back direction. A hole is formed. In this case, the hairbrush has a space between the first base part and the second base part. Furthermore, ventilation is possible through this through-hole, both front and back. [8] In either of the hairbrushes described in [6] and [7] above, the connecting portion is the first connecting The base portion is a part, and the second base portion is in a direction that intersects the front-rear direction. A third base portion that surrounds in the circumferential direction, and an elastic variable connecting the second base portion and the third base portion. It has a second connecting part that can be freely shaped. In this case, the base part is the first base part, the second base Compared to the case where only the first connecting part is present, the pins can conform to the shape of the scalp over a wider area. It can be fitted to further improve the fit. [9] In the hairbrush described in [8] above, the first connecting portion and the second connecting portion are the circumference They are located at equivalent positions in the direction. In this case, the elasticity of the first and second connecting parts Because the direction of deformation can be aligned, the movement of the first base part and the second base part This allows for movement in the same direction, further improving the fit.

[10] Either of the hairbrushes described in [8] and [9] above is the outer edge of the third base portion It is equipped with a handle portion that extends in a direction intersecting the front-rear direction, and the first connecting portion and the second connecting portion The part is provided at the same position as the handle part in the circumferential direction. Compared to the case where each connecting part is located away from the handle, the force required to cause elastic deformation It makes them easier to put on and further improves the fit.

[0033] The rear end of the second base portion 12 is inclined outward. Specifically, see Figures 6 and 7. As shown, the inclination of the rear end of the second base portion 12 is a continuous curved inclination from the front end side. It is inclined. As a result, the rear end of the outer surface 12C of the second base portion 12 also has a similar inclined surface. The second base portion 12 widens so as to curve outwards in a circular arc shape towards the rear end. As a result, the rear end of the second base portion 12 protrudes outward in an overhang shape. In this second base portion 12, the rear end surface 12D faces outward.

[0034] As shown in Figures 6 and 7, the outer peripheral surface 12C of the second base portion 12 has an inclined surface 12E. The inclined surface 12E extends outward and diagonally backward from the outer edge of the second brush surface 12A in a cross-sectional C chamfered shape. It extends. The inclined surface 12E is formed around the entire circumference of the front end of the outer peripheral surface 12C. The base section 12 has multiple second pins 52 erected on this inclined surface 12E. 2 surrounds the outer circumference of the second brush surface 12A on which the first pin 51 is erected, with an inclined surface 1 Multiple pins are erected in a ring shape from 2E. Each second pin 52 is positioned in the same way as each first pin 51, in the front and rear directions. They are erected approximately parallel to the direction. The base end of each second pin 52 is on the inclined surface 12 Since it is erected from E, the base end of the first pin 51 located on the second brush surface 12A It is located further back than the rear position. That is, the brush portion 20 is located at the protruding ends of the multiple first pins 51. This is positioned in front of the protruding ends of the multiple second pins 52. As a result, the brush section 20 is Multiple protruding ends of first pins 51 and multiple protruding ends of second pins 52 are staggered in two stages. This is the structure. The second pin 52 is also provided on the outer circumferential surface 13C of the third base portion 13, which will be described later. There is. By providing the protruding ends of the first pin 51 and the second pin 52 in a stepped shape, the following It exerts the following effect. That is, the hairbrush 1 has a first pin whose protruding end is located further forward. The first pin 51 untangles the hair near the scalp, and moves away from the scalp The tangled hair at that position can be untangled by the second pin 52. By blowing air from a hairdryer on hair that has been untangled more effectively, the hair that is relatively more tangled Compared to other conditions, it allows you to dry your hair faster.

[0035] As shown in Figures 6 and 7, the third base portion 13 is concentrically located on the outside of the second base portion 12. It is arranged such that the third base portion 13 asymptotically approaches the center as it moves from the rear end to the front end. It is curved. The inner circumferential surface 13B of the third base portion 13 is the outer circumferential surface 12 of the second base portion 12 A third ventilation passage 43 is formed between C. The inner circumferential surface 13B of the third base portion 13 is the third ventilation passage This corresponds to the outer wall surface of the base portion 10 among the wall surfaces forming 43. Hereinafter, the third ventilation passage 4 The inner circumferential surface 13B of the third base portion 13, which forms the wall surface 3, is also the third outer wall surface 43B. It will be written.

[0036] As shown in Figures 6 and 7, the rear end of the inner circumferential surface 13B of the third base portion 13 is the second base portion It is located forward of the rear end of the outer circumferential surface 12C of 12. That is, it forms the third ventilation passage 43. Of the wall surfaces, the rear end of the outer peripheral surface 12C of the second base portion 12, which corresponds to the wall surface on the central side, is It is located behind the rear end of the inner circumferential surface 13B of the third base portion 13, which corresponds to the wall surface located on the side. The length of the third base portion 13 in the front-to-back direction is shorter than that of the second base portion 12 on the central side. In other words, among the wall surfaces of the base portion 10 that form the third ventilation passage 43, the wall surface corresponding to the central side 2 The length of the outer peripheral surface 12C of the base portion 12 in the front-rear direction corresponds to the third wall surface located on the outside. It is longer than the inner circumferential surface 13B of the base portion 13.

[0037] The inner circumferential surface 13B of the third base portion 13 has a curvature that gradually decreases from the rear end to the front end. It forms a continuous surface with a roughly arc-shaped cross-section. The inner diameter of the inner circumferential surface 13B of the third base portion 13 is The rear end is larger than the front end. The inner circumferential surface 13B of the third base portion 13 is the same as the first base portion 1 1. Similar to the inner circumferential surfaces 11B and 12B of the second base portion 12, ridge-like undulations 6 extending in the front-rear direction Multiple 0s are formed in a row in the circumferential direction. The outer circumferential surface 13C of the third base portion 13 is the inner circumferential surface 1 Similar to 3B, it is formed in a roughly circular arc shape with a cross-section where the curvature gradually decreases from the rear end to the front end. It is continuous without any steps or unevenness.

[0038] The front surface of the third base portion 13 is the third brush surface 13A. Multiple first pins 51 are erected on the brush surface 13A. The inner edge of the third brush surface 13A is 3. Forms the front end opening of the ventilation passage 43. As shown in Figure 1, the third brush surface 13A is hair When viewed from the front, the brush 1 has an elliptical ring shape, and the first brush surface 11A is concentric. The second brush surface 12A, which surrounds the first brush surface, is further surrounded concentrically. As shown in Figures 6 and 7, The third brush surface 13A has its vertical end positioned forward of its horizontal end. In a side view, both ends of the brush surface 13A in the vertical direction are in front of the second brush surface 12A. It is located at the left and right ends of the third brush surface 13A, which is further from the second brush surface 12A. It is located at the rear.

[0039] The outer edge of the third brush surface 13A is adjacent to the outer peripheral surface 13C of the third base portion 13. The base portion 13 has multiple second pins 52 erected on its outer surface 13C. Pin 52 surrounds the outer circumference of the third brush surface 13A on which the first pin 51 is erected. They are erected in a ring shape from the circumferential surface 13C. Each second pin 52 is positioned similarly to each first pin 51, front and back. They are erected approximately parallel to the direction. The protruding length of each second pin 52 from the outer surface 13C is: It is the same length as the first pin 51. From the outer peripheral surface 13C which is set back from the brush surface 13A The protruding ends of each protruding second pin 52 are the same as the protruding ends of the first pin 51 that protrude from the brush surface 13A. It is positioned further back than that. The protruding ends of the multiple second pins 52 erected on the outer peripheral surface 13C are A step is formed between the protruding ends of the multiple first pins 51 on the adjacent inner brush surface 13A.

[0040] The rear end of the third base portion 13 is inclined outward. Specifically, see Figures 6 and 7. As shown, the inclination of the rear end of the third base portion 13 is a curved inclination that is continuous from the front end side. It is inclined. As a result, the outer surface 13C at the rear end of the third base portion 13 has a similar inclination. The third base portion 13 expands so as it curves outwards in a circular arc shape towards the rear end. It is open. As a result, the rear end of the third base portion 13 protrudes outward in an overhang shape. In this third base portion 13, the rear end surface 13D faces outward.

[0041] As shown in Figures 3 to 5, the back surface 10B of the base portion 10 is positioned so that the center side is further back than the outer side. It is located in the vertical direction. Specifically, as shown in Figure 3, the back surface 10B of the base portion 10 is located in the vertical direction. In this case, the outer shape, when viewed from the side, is roughly arc-shaped, with the central part being the most convex towards the rear. Furthermore, the back surface 10B of the base portion 10 is as shown in Figures 4 and 5 in the left-right direction. The outer shape, when viewed from above, is stepped in plan view, with the central part being the most convex towards the rear. In this case, the base portion 10 consists of a first base portion 11, a second base portion 12, And of the third base portion 13, the rear end of the first base portion 11, which is located most centrally, is furthest to the rear. This configuration is such that the rear end of the third base portion 13, which is located on the outermost side, is positioned at the furthest forward point.

[0042] As shown in Figures 1 to 7, in the base portion 10, the ventilation passage 40 is the first ventilation passage 41, It is configured to have a second ventilation passage 42 and a third ventilation passage 43. Each ventilation passage 41, 42, 43 is Starting from the center of the base section 10, the first ventilation passage 41, the second ventilation passage 42, and the third ventilation passage 43 are arranged in that order. It is formed in a roughly concentric manner. The first ventilation passage 41 is located inside the through hole that penetrates the first base portion 11. It is formed as a space within the circumferential surface 11B (inner wall surface 41A). The second ventilation passage 42 is formed as a space within the first base The outer circumferential surface 11C (second central side wall surface 42A) of part 11 and the inner circumferential surface 12B (second base part 12) 2 It is formed as a space between the outer wall surface 42B). The third ventilation passage 43 is formed as a space between the second base portion 1 The outer circumferential surface 12C of 2 (third central side wall surface 43A) and the inner circumferential surface 13B of the third base portion 13 (third outer It is formed as a space between the side wall surface 43B).

[0043] As shown in Figures 6 and 7, each of the ventilation passages 41, 42, and 43 has a large opening at its rear end. The width is formed to be larger than the size of the opening at the front end. Behind each ventilation passage 41, 42, 43 The position of the end openings is in the order of the first ventilation passage 41, the second ventilation passage 42, and the third ventilation passage 43, with the openings being further back. It is located at the center of the base portion 10. That is, the rear end openings of each ventilation passage 41, 42, 43 are located at the center of the base portion 10. The ventilation passages located on the side are positioned further back than the ventilation passages located on the outside. Also shown in Figure 6. In the cross-sectional view, the ventilation passages 41, 42, and 43 in the hairbrush 1 are, from the front, third The ventilation passages are located in the order of ventilation passage 43, second ventilation passage 42, and first ventilation passage 41. In the plan cross-section shown in Figure 7... In the hairbrush 1, each of the ventilation passages 41, 42, and 43 is, from the front, the first ventilation passage 41 They are located in the order of the second ventilation passage 42 and the third ventilation passage 43.

[0044] As shown in Figures 1 and 2, the second ventilation passage 42 is provided with a first connecting portion 14 at its lower end. In some parts, it forms an elliptical ring (C-shape) when viewed from the front, with a partially cut-off form. (Figure 6) As shown in Figure 7, the second central side wall surface 42A and the second outer wall surface that form the second ventilation passage 42 Of the 42B, the rear end of the second central side wall surface 42A is further back than the rear end of the second outer wall surface 42B. The lengths of the second central side wall surface 42A and the second outer wall surface 42B in the front-rear direction are such that the second central side wall surface 42A is located at the front of the second central side wall surface 42B. The side wall surface 42A is longer than the second outer wall surface 42B. The second central side wall surface 42A is the base part It is inclined outwards from 10. The second central side wall surface 42A is more inclined towards the rear end than towards the front end. It is located on the outside of the base portion 10.

[0045] As shown in Figures 1 and 2, the third ventilation passage 43 is provided with a second connecting portion 15 at its lower end. In some parts, it forms an elliptical ring (C-shape) when viewed from the front, with a partially cut-off form. (Figure 6) As shown in Figure 7, the third central side wall surface 43A and the third outer wall surface that form the third ventilation passage 43 Of the 43B, the rear end of the third central side wall surface 43A is further back than the rear end of the third outer wall surface 43B. The length of the third central side wall surface 43A and the third outer wall surface 43B in the front-rear direction is the length of the third central side wall surface 43A. The side wall surface 43A is longer than the third outer wall surface 43B. The third central side wall surface 43A is the base part It is inclined outwards from 10. The third central side wall surface 43A is more inclined towards the rear end than towards the front end. It is located on the outside of the base portion 10.

[0046] The function of the hairbrush 1 with the above configuration will be explained along with an example of use. When drying hair, the user of hairbrush 1 grasps the handle portion 30 and uses the brush portion 20 While brushing your hair, blow air from the hairdryer onto it. The air from the hairdryer is directed through the airflow channel. It passes through 40 and reaches the brush surface 10A side from the back surface 10B of the base part 10. The hairbrush 1 is The airflow from the hair dryer is guided through the ventilation passage 40 to the brush surface 10A, which is the brushing position. It is possible.

[0047] As long as the airflow from the hair dryer is directed towards the back surface 10B of the base unit 10, the first air passage 4 The air is well guided to either the second ventilation passage 42 or the third ventilation passage 43, which are arranged concentrically around 1. It is introduced and can be circulated towards the brush surface 10A. Therefore, the air from the dryer is directed towards the basin. Regardless of which position on the back surface 10B of section 10 is applied, each of the ventilation passages 41, 42, 43 It enters and flows towards the brush surface 10A. Also, each of the concentric ventilation passages 41, 42, 43 Of these, the second ventilation passage 42 and the third ventilation passage 43 form an annular shape. For this reason, for example, the second The air from the dryer that flows in from a portion of the rear end opening of the ventilation passage 42 and the third ventilation passage 43 Air can flow circumferentially through the ventilation passages 42 and 43, and air can be blown out from the front end opening. It can be released. In this way, the hairbrush 1 receives the airflow from the hair dryer that flows in from the rear end opening. The front opening allows for wider and more widespread discharge, efficiently drying the hair and scalp. It is possible.

[0048] Furthermore, the front side of the first connecting section 14 and the second connecting section 15 has a second ventilation passage in the left-right direction. A space is formed that communicates with 42 and the third ventilation passage 43. Therefore, the second ventilation passage 42 and Air flows in from a portion of the rear end opening of the third ventilation passage 43 and flows through the ventilation passages 42 and 43 in the circumferential direction. The airflow from the dryer passes through without being obstructed by the connecting parts 14 and 15, and extends around the entire circumference. It can be circulated and blown out well from the entire front end opening. In this way, hair Rashi 1 is a dry air that flows in from a portion of the rear end openings of the second ventilation passage 42 and the third ventilation passage 43. The airflow from the hair can be released more widely and from a wider area at the front end opening. As a result, the hair Brush 1 can dry hair and scalp more efficiently.

[0049] As shown in Figures 8 and 9, the airflow from the dryer is directed towards the back of the base portion 10 in the ventilation passage 40. Since the opening on surface 10B is formed to be larger than the opening on brush surface 10A, ventilation It is easy to enter passage 40. Also, the airflow through the ventilation passage 40 is smaller than the opening on the rear side 10B. The airflow is accelerated and blown out from the opening on the brush surface 10A, delivering a strong breeze to the hair and scalp. It is possible.

[0050] As shown in Figures 8 and 9, the airflow from the hair dryer is directed from the diagonal rear of the back surface 10B of the base portion 10. Let's assume the case where it is applied. In this case, of the wall surface forming the second ventilation passage 42, the base portion 1 The rear end of the second central side wall surface 42A, located towards the center of 0, is greater than the rear end of the second outer wall surface 42B. Since it is located at the rear, the airflow from the dryer is received by the second central side wall surface 42A. It can be stopped and enter the second ventilation passage 42 smoothly. Also, the rear end of the second central side wall surface 42A Since it is inclined outward toward the base portion 10, the rear end of the second central side wall surface 42A The airflow from the dryer, once received, is directed towards the front brush surface 10A within the second air passage 42. It is guided well. Also, the airflow from the dryer circulating in the second ventilation passage 42 is directed towards the second outer wall surface. Since ridge-like undulations 60 are formed on 42B, it is good towards the front brush surface 10A. It is guided to the good. Furthermore, the airflow from the dryer circulating in the second ventilation passage 42 is directed to the second central side wall Since the length of 42A in the front-to-back direction is longer than that of the second outer wall surface 42B, the second central side wall surface 42 It can be easily reached along A, close to the scalp H.

[0051] Similarly, among the wall surfaces forming the third ventilation passage 43, the rear end of the third central side wall surface 43A is the 3. Since it is located behind the rear end of the outer wall surface 43B, the back surface 10B of the base portion 10 The airflow from the hair dryer, directed from diagonally behind, is received by the third central side wall surface 43A. It can enter the third ventilation passage 43 smoothly. Also, the rear end of the third central side wall surface 43A is also the base part Since it is inclined outward from 10, it is received by the rear end of the third central side wall surface 43A. The airflow from the dryer is guided well through the third air passage 43 toward the front brush surface 10A. Furthermore, the airflow from the dryer circulating within the third ventilation passage 43 forms ridges on the third outer wall surface 43B. Because the undulating surface 60 is formed, it is well guided toward the front brush surface 10A. Furthermore, the airflow from the dryer circulating within the third ventilation passage 43 has a length in the front-to-back direction that is on the third outer side. It is guided well along the third central lateral wall surface 43A, which is longer than the wall surface 43B, up to near the scalp H. ru.

[0052] Furthermore, the brush section 20 has a plurality of first pins 51. The plurality of first pins 51 are arranged longitudinally. It is erected from a brush surface 10A that curves so that the central part is concave towards the rear. Therefore, as shown in Figure 8, the hairbrush 1 is used in the longitudinal direction of the base portion 10. The protruding end of the first pin 51 can easily conform to the curved shape of the user's scalp H, allowing for good brushing. It is possible to do so.

[0053] On the other hand, the brush surface 10A has a curve in which the center protrudes slightly forward in the shorter direction. It has a curved shape. This curved shape is opposite to the direction of the curve of the user's scalp H. It has a curved shape. However, in the hairbrush 1, the base part 10 is connected to the first base The first connecting portion 14 allows elastic deformation of the base portion 11, the second base portion 12, and the third base portion 13. And it is connected by the second connecting part 15. Therefore, when the brush part 20 is pressed against the scalp H As a result, elastic deformation occurs in the first connecting portion 14 and the second connecting portion 15. The s section 11, the second base section 12, and the third base section 13 are each individually displaced in the front-rear direction. This allows the protruding ends of each first pin 51, which are erected from each of them, to conform to the curved shape of the scalp H. It can be made to conform to the contours.

[0054] Furthermore, the first connecting portion 14 and the second connecting portion 15 are handles in the circumferential direction of the base portion 10. It is located at approximately the same position as part 30. Therefore, when gripping the handle part 30, When using brush 1, elastic deformation occurs in the first connecting portion 14 and the second connecting portion 15. The force is efficiently transmitted from the handle portion 30, which is gripped by the user, to the respective connecting portions 14 and 15.

[0055] Furthermore, the first base portion 11, the second base portion 12, and the third base portion 13 are connected to the first connecting portion 1 4 and the second connecting part 15 are integrally molded and both are made of TPE. Therefore, the first In conjunction with the elastic deformation of the connecting portion 14 and the second connecting portion 15, the first base portion 11 and the second base portion 1 Further elastic deformation occurs in each of the 2 and 3 base parts 13, resulting in a better fit to the scalp H. The feel is further enhanced.

[0056] Also, as shown in Figures 10 and 11, press the brush part 20 of the hairbrush 1 against the scalp H When this happens, elastic deformation occurs in the first connecting portion 14 and the second connecting portion 15, causing the first base portion 11 and the second The base portion 12 and the third base portion 13 are each displaced relative to each other in the front-rear direction. The connecting portion 14 and the second connecting portion 15 are in the front-rear direction compared to each base portion 11, 12, and 13. It is formed with thin walls. For this reason, the hairbrush 1 has a first connecting part 14 and a second connecting part 15 In this way, the first connecting portion 14 and the second connecting portion 15 can be elastically deformed well. By creating this shape, the second base portion 12 is positioned relative to the third base portion 13 in a rearward position. The first base portion 11 moves relative to the third base portion 13, and the second base portion 13 moves backward. It moves further rearward relative to part 12. Then the rear end opening of the second ventilation passage 42, and The rear end openings of the three ventilation passages 43 widen.

[0057] In detail, as shown in Figures 10 and 11, elastic deformation occurs in the first connecting portion 14, and the first bell The rear end of the second ventilation passage 42 opens after the base portion 11 moves relative to the second base portion 12. The size L42A of the opening in the front-to-back direction is such that elastic deformation occurs in the first connecting portion 14 shown in Figures 8 and 9. The size of the rear end opening of the second ventilation passage 42 in the front-to-back direction L42 is larger than the size of the rear end opening of the second ventilation passage 42 in the natural state when it is not in a state of natural conditions. Similarly, elastic deformation occurs in the second connecting portion 15, and the second base portion 12 moves toward the third base portion 1 L43 is the size of the rear end opening of the third ventilation passage 43 in the front-rear direction after it has moved relative to 3 backward. A is the rear end opening of the third ventilation passage 43 when no elastic deformation has occurred in the second connecting portion 15 in its natural state. The size of the opening in the front-to-back direction is larger than L43. Thus, the hairbrush 1 has a brush part Elastic deformation is produced in the first connecting portion 14 and the second connecting portion 15 so that 20 fits to the scalp H. By doing so, the rear end openings of the second ventilation passage 42 and the third ventilation passage 43 widen, and the second This makes it easier for the air from the dryer to enter the ventilation passage 42 and the third ventilation passage 43.

[0058] Furthermore, the brush section 20 has multiple first pins 51, as well as multiple first pins 51 of equal length to each first pin 51. The second pin 52 is erected from a surface located behind the surface on which the first pin 51 is erected. Furthermore, the brush portion 20 of the hairbrush 1 is erected from the brush surfaces 11A, 12A, and 13A. Multiple first pins 51, and a length approximately equal to that of the first pins 51, from the brush surfaces 12A, 13A It also has a two-stage structure having multiple second pins 52 erected from the rear surface. With pin 1 51 in contact with the surface of scalp H, the second pin 52 is not in contact with scalp H. By using this method, you can detangle your hair while drying it quickly. Furthermore, by bending the first pin 51 and bringing it into contact with the surface of the scalp H, the second pin 52 It can also be brought into contact with the scalp H. In this case, the first pin 51 is flexed. By drying your hair while applying a product that works to straighten out frizz, the frizz can be reduced. It can also contribute to harmony. Furthermore, neither the first pin 51 nor the second pin 52 will come into contact with the scalp. Even in that state, the difference in height between the protruding ends of the first pin 51 and the second pin 52 prevents hair from getting in. Hair is located in two positions: one close to the scalp and another further away from the scalp and closer to the surface. Because it can part the hair, it is easier to send air to the entire hair. Moreover, the second pin 52 is Since it is located on the outer circumferential surface side of the base portion 10 than the first pin 51, in particular the outer circumference of the hairbrush 1 It makes it easier to deliver airflow smoothly to the deeper layers of the hair from any direction.

[0059] Furthermore, since the length of the second pin 52 is approximately the same as that of the first pin 51, the protrusion of the second pin 52 Even when the protruding end comes into contact with the scalp H, it can bend with approximately the same stiffness as the first pin 51. For example, In the case of a brush section with a two-tiered structure using two types of pins with different protruding lengths, the protrusion of the shorter pin... When the ends touch the scalp, they may feel harder than long pins, or cause pain. In contrast, hairbrush 1 has the lengths of the first pin 51 and the second pin 52 made approximately equal. This design makes it less likely for discomfort to be felt when the protruding end of the second pin 52 touches the scalp H.

[0060] As described above, the hairbrush 1 according to Example 1 comprises a base portion 10 and this base portion The first pins 51 are a plurality of pins erected from the brush surface 10A, which is the front surface of 10, and The base portion 10 has a first that penetrates from the rear surface 10B to the brush surface 10A. It forms a ventilation passage 41, a second ventilation passage 42, and a third ventilation passage 43. In 42 and 43, the size of the opening at the rear end is larger than the size of the opening at the front end.

[0061] Thus, the ventilation passages 41, 42, and 43 in the hairbrush 1 are located on the back surface of the base portion 10. The opening on side 0B is formed to be larger than the opening on side 10A of the brush surface. Therefore, this Compared to the case where the size of the opening at the rear end of the air passage is the same as that at the front end, Air can easily be drawn into the ventilation passages 41, 42, and 43 from the opening at the rear end. That is, base part 1 It is easier to direct the airflow from the hairdryer, directed from the back side 10B of unit 0, into the ventilation passages 41, 42, and 43. Therefore, the hairbrush 1 directs more airflow towards the brush surface 10A, which is the brushing position. It can be guided. Also, the hairbrush 1 has an opening at the rear end in the ventilation passages 41, 42, 43. Compared to the front end opening, the opening is smaller, so the flow velocity is faster than the flow velocity at inflow, in the ventilation passage 41. Air can be blown out from 42 and 43 towards the brush surface 10A.

[0062] Furthermore, in the hairbrush 1 according to Example 1, the second central side wall that forms the second ventilation passage 42 The rear ends of surface 42A and the second outer wall surface 42B are located further apart than the rear end of the second outer wall surface 42B. The rear end of the side wall surface 42A is located further back. Also, the third central side that forms the third ventilation passage 43 The rear ends of wall surface 43A and the third outer wall surface 43B are further apart than the rear end of the third outer wall surface 43B. The posterior end of the lateral wall surface 43A is located further back. Second central lateral wall surface 42A and third central lateral wall surface 43A corresponds to a wall surface located closer to the center than the outer surface of the base portion according to the present invention. The side wall surface 42B and the third outer wall surface 43B are located outward from the center side of the base portion according to the present invention. It is designed to fit the wall surface on which it will be placed.
