Japanese Utility Model Publication No. 58-18843 (FIG. 1)

  The electric razor of Patent Document 1 can perform a combination shaving with a main blade and a trimmer unit, or a sharp shaving by using a trimmer unit alone, but when shaving a beard on a weak skin such as a cheek or under the jaw, There is a risk of roughening the skin surface.

  An object of the present invention is to provide an electric razor that does not roughen the skin surface when shaving a beard on a weak skin surface such as a cheek or a chin under a trimmer unit.

  The electric razor according to the present invention is an electric razor in which a trimmer unit 78 is provided on a main body case 1 having a blade portion including an inner blade 4 and an outer blade 5 so as to be tiltable. A trimmer holder 101 is tiltably provided on the main body case 1, and a trimmer unit 78 is provided on the trimmer holder 101. The trimmer unit 78 includes a trimmer blade portion including a fixed trimmer blade 80 and a movable trimmer blade 81. The position where the trimmer unit 78 is moved and held toward the blade portion is a combined shaving position where the blade portion and the trimmer blade portion are brought close to each other, and the trimmer unit 78 is moved away from the blade portion. The position where the position is held is the crease position where the trimmer blade portion is separated from the blade portion. The trimmer unit 78 is elastically supported by the trimmer holder 101 so as to be able to reciprocate.

  By connecting the trimmer holder 101 to the main body case 1 so as to be rotatable, the trimmer unit 78 is rotatable with respect to the main body case 1. The trimmer unit 78 is elastically supported by the trimmer holder 101 so as to be capable of reciprocating in the same direction as the axis 101a of the holder 101.

  The trimmer holder 101 is pivotably connected to the main body case 1 via the rotation shaft 94, so that the trimmer unit 78 is rotatable with respect to the main body case 1. The trimmer unit 78 is elastically supported by the trimmer holder 101 so as to be capable of reciprocating in the direction toward the rotation shaft 94.

  The trimmer unit 78 can reciprocate with respect to the trimmer holder 101 in the combination shaving position, and the trimmer unit 78 cannot reciprocate with respect to the trimmer holder 101 in the squeezing position. Features.

  A movement lock structure is provided between the trimmer unit 78 and the main body case 1 so as to restrict the reciprocating movement of the trimmer unit 78 at the sliding position. The movement lock structure includes a contact portion 117 provided on the trimmer base 79 of the trimmer unit 78 and a lock portion 118 provided on the main body case 1. It is characterized in that the movement of the trimmer unit 78 is restricted by receiving the previous contact portion 117 with the lock portion 118 at the wrinkle position.

  A tilt lock structure is provided between the main body case 1 and the trimmer holder 101 so as to restrict the tilt of the trimmer unit 78 in the sliding position.

  The tilt lock structure includes a lock body 120 that is slidably supported by the main body case 1, a lock spring 121 that biases the lock body 120, and an engagement that is provided on the trimmer holder 101 and that is engaged with and disengaged from the lock body 120. It is characterized by including the part 122 and the release body 123 which performs the lock release operation against the urging force of the lock spring 121.

  In the electric razor of the present invention, the trimmer blade can be brought close to the blade and both can be combined. At the time of combi shave, the beard that has fallen on the skin surface is shaved with a trimmer blade, and the raised beard can be immediately cut with the blade portion consisting of the inner blade 4 and the outer blade 5, so the combi shave Can be carried out effectively. Further, in the crease position where the trimmer unit 78 is moved away from the blade portion, the trimmer unit 78 is separated from the blade portion formed by the inner blade 4 and the outer blade 5, so that the blade portion does not interfere with the trimmer unit 78. Usability when using alone is improved. When the trimmer unit 78 is elastically supported so as to be reciprocally movable with respect to the trimmer holder 101 connected to the main body case 1, the trimmer unit 78 can be advanced or submerged following the change of the skin surface condition. Therefore, at the time of combination shaving, the cutting blade portion (trimmer blade portion) of the trimmer unit 78 can be moved in close contact with the unevenness of the skin surface, and the comb shaving of the beard can be performed more lightly. Furthermore, it is possible to prevent the skin surface from being roughened by excessively pressing the cutting edge portion against the skin surface during combi shaving.

  Since the trimmer unit 78 is elastically supported by the trimmer holder 101 so as to reciprocate in the same direction as the axis 101a of the holder 101, it is possible to prevent the trimmer holder 101 from becoming large.

  Since the trimmer unit 78 is elastically supported by the trimmer holder 101 so as to reciprocate in the direction toward the rotation shaft 94, the trimmer unit 78 can be applied even when the trimmer unit 78 receives a pressing force from the skin surface. Sinks toward the rotation shaft 94, and therefore the moment for rotating the trimmer unit 78 is small, and the trimmer unit 78 can be prevented from rotating carelessly.

  When a movement lock structure is provided between the trimmer unit 78 and the main body case 1, the trimmer unit 78 is prevented from sinking in the creaking position, and the trimming unit 78 accurately shapes the sideburns, mustaches, and mustaches. It can be carried out. Further, since the contact portion 117 provided on the trimmer base 79 is received by the lock portion 118 provided on the operation body 20 in the wrinkle position to prevent the trimmer unit 78 from sinking, the float lock structure is simplified. In addition, the sinking operation of the trimmer unit 78 can be reliably regulated.

  If a tilt lock structure is provided between the main body case 1 and the trimmer holder 101 to restrict the tilt of the trimmer unit 78 in the sliding position, the trimmer unit 78 can be applied even when an external force acting on the blade portion acts on the trimmer unit 78. The tilting lock structure restricts the tilting movement, and the posture of the squeezing position can be maintained. Therefore, the trimming unit 78 can accurately shape the sideburns, mustaches, and mustaches.

  Since the lock body 120, the lock spring 121, the engagement portion 122 that engages and disengages with respect to the lock body 120, the release body 123, and the like constitute the movement lock structure, the lock body can be simply operated by sliding the release body 123. The trimmer unit 78 can be tilted by simply releasing the engagement state between the 120 and the engagement portion 122.

The upper end of the lock arm 48 is exposed from the front surface of the mounting portion 19, and an arm lock claw 51 that engages with the lock recess 50 protrudes forward from the exposed portion. The lock arm 48 is pivotally supported by a bracket 52 and an arm shaft 53 provided on the inner surface of the main body case 1 and can swing back and forth, and its upper and lower middle part is received by a stopper 54 facing the arm lock spring 49. ing. As shown in FIG. 3, when the arm lock claw 51 is engaged with the lock recess 50, the upward movement of the outer blade holder 6 is restricted, so that the mounting state of the outer blade holder 6 with respect to the mounting portion 19 is maintained. Can continue.

  Prior to the slide operation of the slide knob 20 from the standby position to the open position, an unlocking structure is provided between the slide knob 20 and the lock arm 48 in order to unlock the holder lock structure. The unlocking structure includes a tunnel-shaped release knob (release operation part) 58 provided at the center of the operation part 22 of the slide knob 20, a relay body 59 that relays the pushing operation of the release knob 58, and a lower end of the lock arm 48. A passive arm 60 that is provided and inherits the operation of the relay body 59 is used. Only the lower end of the release knob 58 is connected to the knob wall of the operation unit 22 and can be elastically deformed in the front-rear direction. Non-slip ribs 61 are formed on the outer surface of the release knob 58, and operation cams 62 for sliding the relay body 59 are formed on the upper inner surface of the release knob 58. The relay body 59 is supported by a guide frame 63 provided inside the main body case 1 so as to be slidable back and forth, and a passive cam surface 64 is formed at the rear end thereof. The outer surface of the release knob 58 in the free state is flush with the previous knob wall. By pushing the release knob 58 in this state forward, the relay body 59 is moved forward to tilt the passive arm 60. Thus, the lock arm 48 can be unlocked against the urging force of the arm lock spring 49.

  At the time of washing with water, first, the release knob 58 is pushed in to unlock the holder lock structure, and in this state, the slide knob 20 is slid from the standby position to the open position, and the outer blade holder 6 is moved to FIG. The first open position shown in FIG. In a state where the slide knob 20 is switched to the open position, the engagement arm 25 falls into the upper arm recess 26 and engages, so that the slide knob 20 can be held in the open position.

  As described above, by sliding the slide knob 20 upward with the release knob 58 pushed in, the outer blade holder 6 is moved to the first opening position, and the lower opening end and the base of the mounting portion 19 are moved. A cleaning opening 68 for introducing cleaning water or discharging the cleaning water together with the hairs can be opened between the end step portion 67. The cleaning opening 68 in this state is opened in a circular shape along the lower opening edge of the outer blade holder 6, and the outer blade holder 6 functions as a lid 69 for opening and closing the cleaning opening 68. When the slide knob 20 is slid downward from the open position to the standby position, the filing chamber S can be closed by closing the cleaning opening 68 with the front and rear walls and the left and right walls of the outer blade holder 6.

  As described above, in a state where the outer blade holder 6 is opened to the first open position, the lower opening of the outer blade holder 6 is located above the bottom wall 27 of the fluff storage chamber S. Specifically, as shown in FIG. 4, the lower opening of the outer blade holder 6 in the first open position is located above the peripheral surface of the inner blade holder 8. As described above, when the position of the lower opening of the outer blade holder 6 in the first open position is positioned above the peripheral surface of the inner blade holder 8, the opening height of the cleaning opening 68 is increased, and the inner blade holder 8 is increased. The entire peripheral surface can be exposed to the cleaning opening 68, and the drive shaft 16 and the bottom wall 27 can be exposed. Note that the lower opening of the outer blade holder 6 is located above the peripheral surface of the inner blade holder 8, as will be described below, the holder swing shaft 40 is moved from the first open position to the holder swing shaft 40. This means that when the swinging operation is performed with the center as the center, the swinging locus of the lower opening of the outer blade holder 6 need only be at a height position that does not contact and buffer the inner blade 4.

  In the first opening position, the user swings the outer blade holder 6 about the holder swinging shaft 40 to move the outer blade holder 6 from above the inner blade 4 to a second opening position (see FIG. 1). Status). In a state where the outer blade holder 6 is opened to the second open position, not only the front, rear, left and right surrounding spaces of the inner blade 4 but also the upper space of the inner blade 4 can be opened to expose the entire inner blade 4. . The imaginary center axis P2 of the outer blade holder 6 in this state is orthogonal to the imaginary center axis P1 of the main body case 1 (see FIG. 1), and the inner surfaces of the outer blade holder 6 and the outer blade 5 that are in the recumbent posture face forward. Can be exposed to.

  In the state where the outer blade holder 6 is positioned at the second open position as described above, the washing water (running water) is poured onto the inner blade 4 and the bottom wall 27 to thereby cause the inner blade 4, the bottom wall 27, or the drive shaft to flow. The hair chips and sebum adhering to 16 can be washed away. If washing with water is performed while the inner blade 4 is driven to reciprocate, the chance of collision between the washing water and the small blade 7 can be increased, and washing with water can be performed more effectively. In addition, by flushing the cleaning water directly onto the inner surfaces of the outer blade holder 6 and the outer blade 5, it is possible to wash away all the fluff and sebum adhering to the inner surfaces of the outer blade holder 6 and the outer blade 5. . In addition, even if the virtual center axis P2 of the outer blade holder 6 and the virtual center axis P1 of the main body case 1 are not perpendicular to each other at an angle of 90 degrees, the same water washing effect as described above can be exhibited. Therefore, in this embodiment, the intersection angle when the virtual center axis P2 of the outer blade holder 6 and the virtual center axis P1 of the main body case 1 are perpendicular to each other includes an angle in the range of 80 degrees to 100 degrees. To do.

  When the amount of fluff in the fluff storage chamber S is large, the washing water is allowed to flow from the washing opening 68 to the inner blade 4 and the bottom wall 27 while the outer blade holder 6 is opened to the first open position. Then, the fluff and sebum adhering to the inner blade 4 and the bottom wall 27 or the outer blade holder 6 and the outer blade 5 are washed away to perform pre-stage cleaning, and then the outer blade holder 6 is opened to the second open position. The cleaning can be performed again. As described above, if the chips and sebum adhering to the outer blade holder 6 and the outer blade 5 are washed away by the pre-cleaning, the chips are peeled off when the outer blade holder 6 is opened to the second open position. It is hygienic because it can eliminate adhesion.

  As described above, in a state where the outer blade holder 6 is positioned at the first open position, the engagement arm 25 falls into the upper arm recess 26 and engages, so that the slide knob 20 moves relative to the main body case 1. The position is held firmly. Further, the outer blade holder 6 in the first open position and the second open position is securely held in each open position by the click pin 44 receiving the urging force of the click spring 45 engaging the click recess 46. Therefore, the slide knob 20 does not wobble. Therefore, the slide knob 20 and the outer blade holder 6 are prevented from wobbling in the first open position and the second open position, and washing with water can be performed accurately and effectively.

  According to the electric razor configured as described above, by simply sliding the slide knob 20 from the standby position to the open position, the circular cleaning opening 68 is opened below the lower opening of the outer blade holder 6, The inner blade 4 and the bottom wall 27 of the fluff storage chamber S can be exposed to the opening space. Further, by swinging the outer blade holder 6 from the first open position to the second open position, the surrounding space of the front, rear, left and right and the upper space of the inner blade 4 are opened, and the entire inner blade 4 is exposed. The inner surfaces of the outer blade holder 6 and the outer blade 5 can be exposed forward. Accordingly, washing water is directly poured onto the outer surfaces of the members of the inner blade 4, the bottom wall 27, and the drive shaft 16 and the inner surfaces of the outer blade holder 6 and the outer blade 5, and the fouling adhered to each portion is washed away together with the washing water. be able to.

  Specifically, when the electric razor is placed in a recumbent posture and flowing water is poured, the inner blade 4 can be washed or the outer blade holder 6 can be washed simply by moving the razor back and forth in the recumbent posture. In addition, the washing with water can be easily performed as much as it is not necessary to change the posture for washing the inner blade 4 and the posture for washing the outer blade holder 6. In addition, the outer blade holder 6 and the inner blade 4 in the second open position are in a positional relationship that is largely separated from the front and rear in a state where the electric razor is in the lying position, so that when washing with water, the outer blade 5 and the outer blade holder While avoiding the 6 and the inner blade 4 from interfering with each other, the inner blade 4 and the surrounding structure, the outer blade 5 and the outer blade holder 6 can be cleaned individually and thoroughly.

  After washing with water, the electric razor is lightly shaken while holding the main body case 1 to remove water droplets adhering around the head of the razor head 2, and then the outer blade holder 6 is positioned at the second open position. By leaving it as it is, it can be dried in a short time. If necessary, hot air from a hair dryer can be blown around the head of the razor head 2 and dried in a shorter time. After drying, the electric razor swings the outer blade holder 6 to return to the first open position, and further slides the slide knob 20 from the open position to the standby position, thereby opening the cleaning opening 68 in the outer blade holder 6. The outer blade holder 6 in the closed state can be locked again with the holder lock structure.

  The outer blade holder 6 in Proposed Example 1 can be attached to and detached from the slide knob 20 via the connecting frame 30, but this is not necessary, and the connecting base 29 of the outer blade holder 6 is bracketed via the holder swinging shaft 40. 41 may be connected. In that case, an outer blade frame that keeps the outer blade 5 in an inverted U shape is separately provided inside the outer blade holder 6, and the outer blade frame is attached to and detached from the outer blade holder 6. 5 can be exchanged.

  (Proposed example 2) FIG. 7 shows a proposed example 2 in which the holder lock structure described in the proposed example 1 is changed. There, a pair of left and right lock claws 71 arranged on both sides of the body case 1, a lock spring 72 for urging the lock claws 71, and an inner surface of the front wall of the outer blade holder 6 corresponding to the lock claws 71 are provided. The lock recess 73 and the like. The upper end of the lock claw 71 is exposed from both sides of the mounting portion 19, and the engaging claw 74 that engages with the lock recess 73 projects laterally from this exposed portion. The lower end of the lock claw 71 is provided with a release button 75 that protrudes from both outer surfaces of the main body case 1. By pushing the release button 75 against the urging force of the lock spring 72, The engagement state of the engagement claw 74 can be released. Since others are the same as the previous proposal example, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted. The same applies to the following embodiments of the present invention.

  At the time of washing with water, the left and right release buttons 75 are pushed in with one hand to release the lock by the engaging claws 74, and the slide knob 20 is slid from the standby position to the open position with the other hand in that state. Thus, the outer blade holder 6 can be positioned at the first open position. Further, the outer blade holder 6 can be opened to the second open position by swinging the outer blade holder 6 about the holder swing shaft 40 in the first open position. After washing with water and drying water droplets adhering around the head of the razor head 2, the outer blade holder 6 is swung to the first open position, and the slide knob 20 is slid from the open position to the standby position. By operating, the outer blade holder 6 can be automatically locked and held by the pair of left and right lock claws 71.
