In this embodiment, the functional structure provided in the functional structure area is composed of a long hair cutting portion 37 for cutting long hair or curly hair. As shown in FIG. 4, the long hair cutting portion 37 is provided on the inner uneven peripheral surface 9b (outer peripheral surface) facing the short hair cutting portion 10 of the head case 9. Two strip-shaped razor blades 38 are arranged in the long hair cutting portion 37, and the razor blade 38 includes a mounting portion 40 formed by bending on the opposite edge of the cutting blade 39. The cutting blades 39 of the razor blade 38 are arranged in parallel with the central axis P2 of the razor head 2, and are provided back to back with each cutting blade 39 facing outward. The razor blade 38 is detachably provided with respect to the head case 9 by inserting the mounting portion 40 into the mounting slit 41 provided in the head case 9. The cutting blade 39 of the razor blade 38 may be arranged in a state of being tilted by about 15 degrees with respect to the central axis P2 of the razor head 2 in front view. Further, the razor blade 38 can be inserted into the mounting slit 41 via a resin fixed to the mounting portion 40 and mounted.

As described above, when the short hair cutting portion 10 is composed of the shear blade structure and the functional structure is composed of the long hair cutting portion 37, the long hair and the curly hair can be easily cut by the long hair cutting portion 37. After rough shaving the thin hair, finish shaving is performed at the short hair cutting portion 10, and beard cutting from rough shaving to finish shaving can be efficiently performed. Further, when the strip-shaped razor blade 38 is arranged in the long hair cutting portion 37, the structure of the long hair cutting portion 37 can be simplified and the cost increase of the electric razor due to the provision of the long hair cutting portion 37 can be suppressed.

When two razor blades 38 are provided back to back with the cutting blades 39 of each razor blade 38 facing outward, each razor blade 38 is used properly according to the situation of long hair or curly hair that has fallen on the skin surface. By cutting, rough shaving can be performed quickly.
When the cutting blade 39 of the razor blade 38 is arranged parallel to the central axis P2 of the razor head 2, the razor head 2 is operated in the direction intersecting the central axis P2, so that long hair and curly hair can be accurately cut by the razor blade 38. Can be disconnected. Further, a razor blade 38 having a larger vertical dimension can be provided. Therefore, the usability of the razor blade 38 can be improved, and rough shaving can be performed more quickly.

When the razor blade 38 and the short hair cutting portion 10 are provided on the opposite outer peripheral surfaces of the head case 9, the gripped electric razor is rotated half a turn to perform a rough shave by the razor blade 38 and a finish shaving by the short hair cutting portion 10. Can be used properly to cut the beard.
If the razor blade 38 is detachably provided on the head case 9, the razor blade 38 with reduced sharpness can be replaced with a new razor blade 38, and the razor blade 38 with good sharpness always efficiently removes long hair and curly hair. Can be disconnected.

A skin protection portion 44 is formed on the outer peripheral surface of the head case 9 so as to face the cutting blade 39 of the razor blade 38, and the skin protection portion 44 of the present embodiment is each of the grooves formed in the head case 9. It was composed of a tip portion 45 facing the cutting blade 39 of the razor blade 38. The heights of the cutting edge 39 and the tip 45 in the front-rear direction are the same. By forming the skin protection portion 44 on the outer surface of the head case 9 facing the cutting blade 39 of the razor blade 38 in this way, it is possible to prevent the skin from dripping into the space facing the cutting blade 39 of the razor blade 38. The blade 39 can cut long hair and curly hair while preventing the skin from being damaged. Further, if the skin protection portion 44 is formed by the tip portion 45 of the groove formed in the outer peripheral surface of the head case 9, the skin protection portion 44 can be formed with a simple structure without separately providing a member for protecting the skin. It is possible to suppress an increase in the cost of the electric razor due to the provision of the protection unit 44.

The above functional structure includes a long hair cutting portion 37 and a functional structure including a skin contact body 48 having a hair raising function. The skin contact body 48 is provided on the tip surface 9c of the head case 9, and is configured as a partially spherical protrusion group (concave and convex protrusion group) 49 formed on the tip surface 9c. As described above, since the tip surface 9c of the head case 9 is inclined with respect to the central axis P2 of the razor head 2, when the razor blade 38 is applied to the skin surface, the razor head 2 is applied to the skin surface. Can be tilted. As a result, the target position can be easily seen and the tip surface 9c can be moved accurately, so that the tip surface 9c can be moved pinpointly to accurately raise long hair or curly hair. Further, since the tip surface 9c of the head case 9 is inclined downward from the side of the outer biased peripheral surface 9a of the head case 9 toward the side of the inner biased peripheral surface 9b, when raising hair with a skin contact body, the hair is raised. The short hair cutting portion 10 can be kept away from the skin surface, and there is no possibility that long hair or curly hair is accidentally caught by the short hair cutting portion 10 and the beard is pulled in a state where the electric razor is not driven. A rib-shaped protrusion 62 can be provided on the tip surface 9c of the head case 9 in place of or in combination with the protrusion group (concave and convex protrusion group) 49.

As described above, in the electric razor of the present embodiment, since the functional structure area F2 is provided facing the tip surface 9c of the razor head 2 and the virtual space S, the electric razor is placed on the mounting table in a lying position. In the above, since it is possible to prevent the long hair cutting portion 37 provided on the inner uneven peripheral surface 9b from coming into contact with the mounting surface, it is possible to prevent the long hair cutting portion 37 from being damaged due to contact or collision with the mounting surface.

A vibrating structure for vibrating the razor head 2 is provided inside the tip side of the head case 9. The excitation structure is provided on the support frame 22, and is composed of an excitation shaft 51, an eccentric weight 52 fixed to the excitation shaft 51, and the like. In such a vibration structure, vibration on a plane orthogonal to the vibration axis 51 is generated. The vibration shaft 51 is arranged so that vibration including a vibration component for vibrating the fixed blade 14 in the thickness direction is generated. In this embodiment, the vibration shaft 51 is aligned with the central axis P2 of the razor head 2. Arranged in parallel. By the way, when the vibration generated by the exciting structure does not include the vibration component for vibrating the fixed blade 14 in the thickness direction, the fixed blade 14 held in a flat plate shape is in a state along the thickness direction. When the vibration shaft 51 is provided, and if the above conditions are not satisfied, the generated vibration includes a vibration component in the thickness direction of the fixed blade 14, even if it is slight. Therefore, when the fixed blade 14 is held in an arch shape as in the present embodiment, the fixed blade 14 is vibrated in the thickness direction due to the generated vibration regardless of the orientation of the vibration shaft 51. The vibration component of is included.

As shown in FIG. 4, the vibration axis 51 assumes a tangent line T at the top of the arch cross section of the fixed blade 14 held in an arch shape by the head case 9 and a virtual reference line Q orthogonal to the central axis P2 of the razor head 2. When doing so, it is arranged in a state orthogonal to the virtual reference line Q. Specifically, in the excitation structure of this embodiment, the rotary blade shaft 17 also serves as the excitation shaft 51, and is arranged in parallel with the central axis P2 of the razor head 2. The eccentric weight 52 is externally fitted and fixed to the rotary blade shaft 17 projecting upward from the tip support frame 23 of the support frame 22. When the motor 3 is started, the eccentric weight 52 is rotationally driven together with the movable blade 15 to generate vibration that follows a horizontal plane (follows a plane orthogonal to the vibration axis 51). Due to the generated vibration, the fixed blade 14 held in an arch shape vibrates in the thickness direction in the entire peripheral portion thereof. At this time, since the rotary blade shaft 17 is arranged on the rear side of the central axis P2 of the razor head 2, vibration is more easily transmitted to the short hair cutting portion 10 side. In this way, if the vibration shaft 51 is arranged parallel to the central axis P2 of the razor head 2, that is, vibration including a vibration component for vibrating the fixed blade 14 in the thickness direction is generated, it is easy to apply the vibration shaft 51 to the skin surface. The fixed blade 14 can be vibrated in the thickness direction at the top of the peripheral surface portion of the fixed blade 14 often used in the main, and therefore, the fixed blade 14 is vibrated in a direction orthogonal to the skin surface to be intermittent. Since the fixed blade 14 can be pressed against the skin surface, the whiskers can be introduced deeper inside the fixed blade 14 and deeply shaving in the finish shaving. Further, since the rotary blade shaft 17 of the movable blade 15 also serves as the vibration shaft 51, it is not necessary to provide a motor dedicated to the vibration structure, and the structure of the electric razor is simplified and the vibration structure is provided. The cost increase of the electric razor can be suppressed. Since the motor 3 is provided in the main body case 1, the size of the razor head 2 can be reduced and the structure can be simplified.

As described above, when the oscillating structure for vibrating the razor head 2 is provided inside the tip side of the head case 9, the movable blade 15 of the short hair cutting portion 10 is vibrated by the vibration generated by the oscillating structure. The sharpness can be improved and the whiskers can be cut efficiently. Further, by providing the vibration structure on the tip side of the head case 9 away from the main body case 1 that also serves as a grip, it is possible to minimize the transmission of the vibration generated by the vibration structure to the fingers gripping the electric razor. ..
According to the vibration structure provided with the support frame 22, the vibration generated by the vibration structure can be efficiently transmitted to the movable blade 15, so that the sharpness of the movable blade 15 can be further improved. Further, since the contact pressure between the movable blade 15 and the fixed blade 14 changes depending on the vibration, the sliding contact resistance of the movable blade 15 made of the rotary blade can be reduced, the load on the motor 3 is reduced, and the power consumption is suppressed. Can be planned.

As shown in FIG. 4, the long-haired cutting portion 37 on which the razor blade 38 is arranged faces the connecting frame 24 with the head case 9 on the inwardly biased peripheral surface 9b side of the head case 9 in between. Further, the inner surface side of the inner uneven peripheral surface 9b and the front surface of the connecting frame 24 are arranged so as to be in contact with each other. By arranging the long-haired cutting portion 37 and the connecting frame 24 in this way, the vibration generated by the oscillating structure can be applied to the razor blade 38 via the connecting frame 24 and the head case 9, so that the razor blade 38 can be affected. The sharpness can be improved, and long hair and curly hair can be cut more efficiently. The inner surface side of the inner uneven peripheral surface 9b and the front surface of the connecting frame 24 do not necessarily have to be in contact with each other, and may be arranged with a slight gap.

As shown in FIG. 3, an illuminating body 55 that illuminates the razor head 2 is provided at the upper end of the front portion of the main body case 1 facing the virtual space S. The illuminating body 55 is composed of a bullet-shaped LED, and its optical axis is directed toward the long-haired cutting portion 37. A diffusion block 56 is arranged at the tip of the illuminating body 55 so as to diffuse the light emitted from the illuminating body 55. When using an electric razor, the beard can be cut while illuminating the razor head 2, the long hair cutting portion 37, and the skin surface with the illumination light emitted from the illuminating body 55, so that the condition of the beard and the cutting status of the beard can be accurately grasped. However, the beard can be cut accurately.

When using an electric razor, first, the tip surface 9c of the head case 9 is applied to the skin surface, and long hair or curly hair that has fallen on the skin surface is raised by the skin contact body 48 to make it easy to cut. Next, long hair and curly hair are roughly shaved at the long hair cutting portion 37 on which the razor blade 38 is arranged, and further, finish shaving is performed at the short hair cutting portion 10. In this way, a series of shaving operations such as raising hair, rough shaving, and finishing shaving can be efficiently performed with only one electric razor.

(Example 2) FIGS. 5 and 6 show Example 2 of the electric razor according to the present invention. In this embodiment, as shown in FIG. 5, a hair-raising body 59 composed of a group of protrusions (unevenness) capable of applying pressure to the skin surface at a point is formed along the skin protection portion 44. The hair-raising body 59 functions as a part of the skin protection portion 44, and increases the chance of contact between the skin protection portion 44 and the skin surface. Further, as shown in FIG. 6, each mounting portion 40 of the razor blade 38 is adhesively fixed to the mounting slit 41 in a state where the cutting blade 39 faces the top of the raised body 59. On the outer surface of the razor blade 38, a large number of protective wires 60 are arranged at equal intervals in a state of intersecting the cutting blade 39 of the razor blade 38, and both ends thereof are embedded and fixed in the head case 9. Since the left and right ends of the protective wire 60 in this state are held immovably up and down by the raised body 59 adjacent to the top and bottom, when the razor blade 38 comes into contact with the skin surface, the protective wire 60 is held against the cutting blade 39. It can prevent it from moving up and down. Since the other parts are the same as those in the first embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. The same shall apply in the following description.

As described above, when the raised body 59 is formed on the skin protection portion 44, the long hair and the curly hair that has fallen on the skin surface are raised by the raised body 59, and the chance of contact with the razor blade 38 is increased, so that the long hair and the curly hair are formed. Cutting can be performed more efficiently.
If the protective wire 60 is provided on the outer surface of the razor blade 38, the protective wire 60 can prevent the cutting blade 39 from being unnecessarily pressed against the skin surface, so that the skin contact of the razor blade 38 can be softened. The damage that the blade 38 gives to the skin surface can be reduced.
When the protective wire 60 is held immovably by the raised body 59, it is not necessary to separately provide a member for holding the protective wire 60, and a simple configuration prevents the protective wire 60 from slipping, and the razor blade 38 is on the skin surface. You can do less damage to your hair.

(Example 3) FIG. 7 shows Example 3 of the electric razor according to the present invention. In this embodiment, a long hair cutting portion 37 composed of a razor blade 38 is provided on the outer peripheral surface of the head case 9 in a state of being adjacent to the short hair cutting portion 10. When the short hair cutting portion 10 and the razor blade 38 are adjacent to each other in this way, the razor blade 38 and the short hair cutting portion 10 are applied to the skin surface for rough shaving by simply twisting the wrist lightly without having to change the electric razor. Since the finish shave can be performed, effective hair cutting can be performed in a short time. Further, since the short hair cutting portion 10 does not face downward when the razor blade 38 is used, it is possible to prevent the hair dust cut by the short hair cutting portion 10 from spilling out.

(Example 4) FIG. 8 shows Example 4 of the electric razor according to the present invention. In this embodiment, the head case 9 (razor head 2) is composed of a plurality of rib-shaped protrusions 62 long in the axial direction on the inwardly biased peripheral surface 9b (outer peripheral surface) facing the short hair cutting portion 10 of the head case 9. A skin contact body 48 is provided, and a long hair cutting portion 37 composed of one razor blade 38 is provided on the tip surface 9c of the head case 9. The head case 9 is composed of a cylindrical case 63 and a tip piece 64 that is externally fitted to the tip of the cylindrical case 63, and the razor blade 38 is mounted with a mounting portion 40 so that the cutting blade 39 is aligned in the left-right direction. It is adhesively fixed to the slit 41. The skin protection portion 44 facing the cutting blade 39 of the razor blade 38 is composed of rib-shaped protrusions formed on the tip surface 9c of the head case 9, and the cutting blade 39 of the razor blade 38 is the skin protection portion 44. It is installed so as to face the top of the. The razor blade 38 of this embodiment is replaced together with the tip piece 64 of the head case 9. The rib-shaped protrusion 62 may be provided with a plurality of thin fin-shaped bodies in close proximity to each other. In this case, the fin-shaped bodies are made of silicon rubber or nitrile rubber in order to exhibit elasticity and flexibility. It is preferable to form it with a flexible rubber material such as. A protrusion group (concave and convex protrusion group) 49 can be provided on the outer peripheral surface of the head case 9 in place of or in combination with the rib-shaped protrusion 62.

The vibration structure is composed of a vibration motor 65 dedicated to the vibration structure and an eccentric weight 52 fixed to the output shaft of the vibration motor 65, and the output shaft of the vibration motor 65 also serves as the vibration shaft 51. ing. The output shaft of the oscillating motor 65 is arranged parallel to the central axis P2 of the razor head 2 orthogonal to the virtual reference line Q, and is mounted on the motor fixing seat 66 provided on the inner surface of the upper front side of the cylindrical case 63. There is. In this state, the lower end surface of the vibration motor 65 is in close contact with the upper surface of the tip support frame 23. As a result, the vibration generated by the vibrating structure is transmitted to the head case 9 and the support frame 22. In this way, if the vibration shaft 51 is arranged parallel to the central axis P2 of the razor head 2, that is, vibration including a vibration component for vibrating the fixed blade 14 in the thickness direction is generated, it is easy to apply the vibration shaft 51 to the skin surface. At the top of the peripheral surface portion of the fixed blade 14 often used in the main, the fixed blade 14 can be vibrated in the thickness direction, and therefore the fixed blade 14 can be vibrated in a direction orthogonal to the skin surface. As a result, the fixed blade 14 can be intermittently pressed against the skin surface, so that the whiskers can be introduced deeper inside the fixed blade 14 and deeply ground in the finish shaving. Further, since the vibration motor 65 is arranged on the front side of the central axis P2 of the razor head 2, the vibration is more easily transmitted to the skin contact body 48 side. Therefore, the vibration generated by the vibrating structure can be efficiently acted on the skin contact body 48, and long hair or curly hair that collapses on the skin surface can be generated more quickly. The vibration structure provided with the vibration motor 65 has an advantage that the degree of freedom in the arrangement position of the vibration structure is improved and the vibration applying direction can be freely set. Since the fixed blade 14 is held in an arch shape in the present embodiment as in the previous embodiment 1, the fixed blade 14 is subjected to the generated vibration regardless of the orientation of the vibration shaft 51. A vibration component for vibrating in the thickness direction is included. In each of the above-described embodiments, the skin contact body 48 composed of a plurality of rib-shaped protrusions 62 is not provided, but such a skin contact body structure naturally has other functional structures on the outer peripheral surface of the case 9. For example, it can be configured in combination with a long hair cutting portion 37 for cutting long hair or curly hair, or a hair dust discharging structure described later. The same applies to the skin contact body structure of the following examples.

The oscillating motor 65 is rotated 90 degrees around the virtual reference line Q from the state of this embodiment so that, for example, the output shaft (exciting shaft 51) of the oscillating motor 65 is orthogonal to the central axis P2 of the razor head 2. It can be placed in a state of being. In this case, at the top of the peripheral surface portion of the fixed blade 14, the razor head 2 can be vibrated in the central axis P2 direction while the fixed blade 14 is vibrated in the thickness direction. Therefore, the whiskers can be cut off by the movable blade 15 and the razor blade 38 while intermittently pressing the fixed blade 14 against the skin surface, so that the sharpness of the double-edged blades 15 and 38 can be improved. The vibration shaft 51 is not only in a state orthogonal to the central axis P2 of the razor head 2 as described above, but also has a thickness at the top of the fixed blade 14 regardless of the position rotated around the virtual reference line Q. It can be vibrated in the direction.

The vibration motor 65 in this embodiment can be arranged by forming a motor fixing seat 66 on the rear side of the top of the cylindrical case 63. In this case, since the vibration motor 65 is arranged in the vicinity of the fixed blade 14, vibration can be effectively applied to the fixed blade 14. At this time, if the output shaft of the vibration motor 65 is set in the same direction as the central axis P2 of the razor head 2, vibration can be applied in the thickness direction on all the surfaces of the fixed blade 14 in the circumferential direction, so that deep shaving is effective. Can be done Further, the vibration motor 65 can also be fixed to a fixed seat provided on the support frame 22. In this case, the vibrating structure can effectively vibrate the top of the fixed blade 14 in the thickness direction via the movable blade 15, and the fixed blade 14 makes it easier to transmit the vibration, further enhancing the pulling effect. Can be enhanced. In the present invention, "the support frame 22 is provided with a vibration-exciting structure" means a form in which the vibration-promoting structure is assembled to the support frame 22 as in the first embodiment, or as in the present embodiment. It also includes a form in which the vibration motor 65 is fixed to a component other than the support frame 22 and a part thereof is brought into contact with the support frame 22.

(Example 5) FIGS. 9 and 10 show Example 5 of the electric razor according to the present invention. In this embodiment, as shown in FIG. 9, two flat plate-shaped razor blades 38 are provided on the tip surface 9c of the head case 9, and the facing edges of the cutting blade 39 are inclined with respect to the tip surface 9c. The mounting portion 40 is mounted on the mounting slit 41 to form a long hair cutting portion 37. As shown in FIG. 10, the cutting blades 39 of the razor blade 38 mounted on the mounting slit 41 are arranged so as to face the left and right skin protection portions 44, respectively.

If the razor blade 38 is provided on the tip surface 9c of the razor head 2 as in Examples 4 and 5, the tip surface 9c of the razor head 2 can be moved more freely with respect to the skin surface. It is possible to accurately cut long hair and curly hair in the affected area. In addition, since the razor blade 38 can be finely operated, long hair and curly hair in a narrow area can be accurately cut.

(Example 6) FIGS. 11 to 13 show Example 6 of the electric razor according to the present invention. In this embodiment, as shown in FIG. 11, the functional structure is composed of a skin contact body 48 composed of a raising rod 69, and an L-shaped support arm 70 is attached to the upper end (one end) of the raising rod 69. It is provided integrally. The tip surface 9c of the head case 9 is formed in a horizontal plane, and the raising rod 69 has a head in which the middle portion of the vertical axis portion of the support arm 70 is rotatably supported by the arm support hole 71 of the head case 9. It can rotate around the case 9. The raising rod 69 faces the outer peripheral surface of the head case 9 through a gap at any position around the head case 9, and at least the raising rod 69 faces the long hair cutting portion 37 in the virtual space S. In the state of being located inside, the raising rod 69 is housed inside the outer shape of the cross section of the main body case 1. Further, the facing gap E1 of both 38 and 69 in the state where the raising rod 69 and the razor blade 38 face each other is that of both 10.69 in the state where the raising rod 69 and the short hair cutting portion 10 face each other. It is set smaller than the facing gap E2. As shown in FIG. 12, the hair raising rod 69 is composed of three rib-shaped protrusions 62 formed long in the axial direction of the raising rod 69, except for the peripheral surface facing the outer peripheral surface of the head case 9. A raising body 59 is provided.

A moderation structure is provided between the head case 9 and the support arm 70 to hold the raising rod 69 in a predetermined position, and the raising rod 69 faces the razor blade 38 and the short hair cutting portion 10 It is configured so that the position can be maintained in a state facing the. As shown in FIG. 13, the moderation structure is such that the moderation recess 72 provided on the head case 9 side, the moderation protrusion 73 provided on the support arm 70 side, and the moderation recess 72 and the moderation protrusion 73 are held in an engaged state. It is equipped with a force spring 74 and the like. A support boss 75 is provided on the inner surface of the tip of the head case 9, and moderation recesses 72 are formed in the front and rear on the lower surface side of the boss 75. Further, in the center of the support boss 75, an arm support hole 71 that rotatably supports the vertical axis portion of the support arm 70 is formed. A flange body 76 that is fixed so as not to rotate is provided in the middle of the vertical shaft portion of the support arm 70, and a moderation protrusion 73 is formed so as to protrude on the front side of the upper surface of the flange body 76. The moderation structure is covered with a bottomed tubular cover body 77 that is externally fitted and fixed to the support boss 75, and an urging spring 74 is arranged between the flange body 76 and the inner surface of the bottom wall of the cover body 77. .. The lower end of the vertical shaft portion of the support arm 70 is rotatably supported by the bottom wall of the cover body 77.

The raising rod 69, which is held at a position facing the long hair cutting portion 37 in the moderation structure, is rotated by pushing the support arm 70 downward to release the engagement state between the moderation recess 72 on the front side and the moderation protrusion 73. It becomes movable. In this state, the moderation protrusion 73 is engaged with the moderation recess 72 on the rear side by rotating the support arm 70 toward the short hair cutting portion 10 side to release the push-in, and the hair raising rod 69 cuts the short hair. The position is held at a position facing the portion 10. When holding the raising rod 69 on the side of the long hair cutting portion 37 again, the support arm 70 is pushed downward to disengage the rear moderation recess 72 and the moderation protrusion 73, and the moderation protrusion 73 is placed on the front side. It may be engaged with the moderation recess 72. In this way, the holding position of the raising rod 69 can be changed by pushing and rotating the support arm 70. In FIG. 13, reference numeral 78 is a regulation flange that defines the push-in limit of the support arm 70. Also in this embodiment, since the razor head 2 is provided with the skin contact body 48, the long hair cutting portion 37, and the short hair cutting portion 10, a series of shaving operations such as raising hair, rough shaving, and finishing shaving can be performed by one electric device. It can be done efficiently with only a razor.

As described above, when the hair raising rod 69 is opposed to the outer peripheral surface of the head case 9 through a gap, the hair raising rod 69 is brought into contact with the skin surface before the head case 9 to accurately raise long hair and curly hair. Can be done. Further, when the hair raising body 59 composed of the rib-shaped protrusions 62 is formed on the hair raising rod 69, the chance of contact between the hair raising rod 69 and the skin surface can be increased, and long hair or curly hair can be raised more accurately.

When the raising rod 69 is allowed to rotate around the head case 9, the posture of the electric razor is significantly changed by locating the raising rod 69 near the short hair cutting portion 10 or the long hair cutting portion 37. It is possible to raise the hair with the hair raising rod 69 and cut the whiskers with the short hair cutting portion 10 or the long hair cutting portion 37. Further, by locating the hair raising rod 69 far away from the short hair cutting portion 10 or the long hair cutting portion 37, the hair raising by the hair raising rod 69 and the beard cutting by the short hair cutting portion 10 or the long hair cutting portion 37 are clearly used properly. be able to. Therefore, since the usage pattern can be selectively selected depending on the position of the raising rod 69, the electric razor can be used in the usage pattern preferred by the user. For example, with the hair raising rod 69 facing the short hair cutting portion 10, the movable blade 15 (motor 3) is driven to actively use the hair raising rod 69 and the short hair cutting portion 10. be able to. In this case, the short hair cutting portion 10 can cut the beard while raising the beard with the raising rod 69. Therefore, it is possible to effectively cut the beard. At this time, the moderation structure is set so that the raising rod 69 can hold the position of the raising rod 69 at an arbitrary position in the circumferential direction of the fixed blade 14 (for example, three places at the center and both ends in the circumferential direction of the fixed blade). Then, the raising rod 69 does not rotate carelessly.

When the raising rod 69 is located in the virtual space S and the raising rod 69 is contained inside the outer shape of the cross section of the main body case 1, the electric razor is placed on the mounting table in a lying position. In this state, it is possible to prevent the raising rod 69 from coming into contact with the mounting surface, so that damage to the raising rod 69 due to contact or collision with the mounting surface can be prevented.

If it is set smaller than E2, the razor blade 38 can be more reliably protected by the raising rod 69. Further, in the state where the hair raising rod 69 faces the short hair cutting portion 10, there is no possibility that the long hair or the curly hair is caught by the short hair cutting portion 10 and the whiskers are pulled in the state where the electric razor is not driven. ..

If a moderation structure is provided so that the raising rod 69 can be held in a state of facing the short hair cutting portion 10 or the long hair cutting portion 37 composed of the razor blade 38, the razor blade 38 can be used while the short hair cutting portion 10 is in use. Since it can be covered with the raising rod 69, it is possible to prevent the razor blade 38 of the long hair cutting portion 37 from accidentally damaging the skin surface. Further, since the short hair cutting portion 10 can be covered with the raising rod 69 while the long hair cutting portion 37 is in use, it is possible to prevent clothes or the like from being accidentally caught in the short hair cutting portion 10.

In this embodiment, a long-haired cutting portion 37 composed of one razor blade 38 is provided on the tip surface 9c of the head case 9. Although the hair dust discharge structure including the discharge window 80 and the opening / closing body 81 is not provided in each of the above-described embodiments, such a hair dust discharge structure naturally has other functional structures on the outer peripheral surface of the case 9. For example, it can be configured in combination with a long hair cutting portion 37 for cutting long hair or curly hair, or a rib-shaped protrusion 62 having a hair raising function. The same applies to the hair dust discharge structure of the following examples.

When cleaning the inside of the hair dust chamber R, the shutter 82 is opened as shown in FIG. 16 to maintain the posture of the electric razor so that the discharge window 80 faces downward. In this state, the washing water is supplied from the short hair cutting portion 10 to the hair dust chamber R, and the hair dust is discharged together with the washing water through the discharge opening 87 and the discharge window 80 to wash the hair dust chamber R. At this time, by starting the motor 3, the washing water can be stirred in the hair dust chamber R to wash the hair dust chamber R more effectively. If the shutter 82 is left open even after washing, the drying of the hair dust chamber R is promoted. The washing water can be supplied from the discharge window 80 and the washing water can be discharged together with the whiskers from the short hair cutting portion 10. That is, the discharge window 80 can be an introduction window for washing water. Hair dust can also be discharged by shaking the electric razor with the shutter 82 open without using washing water.

As described above, when the peripheral wall of the head case 9 facing the functional structure area F2 is provided with the functional structure including the discharge window 80 and the opening / closing body 81 for opening / closing the discharge window 80, the opening / closing body 81 is opened and the discharge window 80 is provided. By opening the head case 9 toward the outer surface, the hair dust in the hair dust chamber R can be easily discharged. Further, by supplying the washing water from the short hair cutting portion 10, the hair dust can be discharged together with the washing water while washing the inside of the hair dust chamber R with water. Therefore, the hair dust accumulated in the hair dust chamber R can be easily cleaned, and the hair dust chamber R can be easily cleaned. Further, if the opening / closing body 81 is composed of the shutter 82, the structure of the opening / closing body 81 can be simplified, and the discharge window 80 can be opened toward the outer surface of the head case 9 by a simple operation of simply sliding the shutter 82. Can be done. According to the shutter 82 provided with the operation piece 83 for finger hooking, the operation piece 83 can be used to accurately slide the shutter 82 with one hand. At this time, since the operation piece 83 is provided near the main body case 1 of the shutter 82, it is easy to operate when opening and closing the shutter 82 while holding the main body case 1.

(Example 8) FIGS. 17 and 18 show Example 8 of the electric razor according to the present invention. In this embodiment, the head case 9 is provided with the same opening / closing body 81 as in the seventh embodiment, but is different from the seventh embodiment in that the upper end of the guide groove 86 is exposed to the tip surface 9c of the head case 9. According to such an opening / closing body 81, most (part) of the shutter 82 can be projected from the tip of the head case 9 in a state where the shutter 82 is slid to open the discharge window 80. The shutter frame 85 viewed from the front is formed in a U shape. By projecting most of the shutter 82 from the tip of the head case 9 in this way, the shutter 82 can indicate that the discharge window 80 is open. Further, since it can be visually confirmed that the discharge window 80 is open, it is possible to effectively prevent the whiskers from being cut while the discharge window 80 is open.
