Description

  The present invention relates to an electric razor in which a razor head is floatingly supported with respect to a main body case.

This type of electric shaver is well known in Japanese Patent Application Laid-Open No. 2000-14943 according to the applicant's application. There, a razor head and a motor are assembled to the top and bottom of a motor base to constitute a razor unit, and a pair of left and right springs provided between the motor base and the case body support the razor unit in a floating manner. This electric razor can float freely up and down, but cannot float left and right or back and forth. Japanese Patent Application Laid-Open No. Hei 8-182872 discloses an electric razor that can float in the vertical and horizontal directions. There, a motor and a razor head are assembled to a motor case, and these three members are configured as one razor unit, and the razor unit is supported by the main body case so as to float. Specifically, three support legs arranged in a triangular shape are supported by the main body case so as to be vertically slidable, and the motor case is pushed up and biased by a spring disposed between the support legs. The support leg and the motor case are connected via a spherical seat, and the three spherical seats can absorb the tilting of the razor head in the front-rear, left-right, or diagonal directions.
JP 2000-14493 A JP-A-8-182872

  In the above-described electric razor, the motor case is floated and supported by the support leg and the spring, and the tilting motion is absorbed by the spherical seat above the support leg, so that the motor case is supported in a rather stable state. Therefore, when the beard cutting surface is moved along the skin surface, the response operation when the beard cutting surface tilts following the change of the skin surface is slow, and the razor unit cannot always be tilted smoothly. The sliding friction of the support legs and the sliding friction of the spherical seat also reduce the response speed when the whisker cutting surface tilts.

  The object of the present invention is to allow the razor head to smoothly tilt following the skin surface change, and therefore to effectively follow the whisker by keeping the beard cutting surface of the razor head in close contact with the skin. The object is to provide an electric razor that can be cut.

  In the present invention, the razor head 2B is floated and supported in a rather unstable state so that the razor head 2B can be smoothly tilted following the skin surface change. Specifically, the electric razor of the present invention includes a razor head 2B including a motor 19, an inner blade 20 driven by motor power, and the like, and a main body case 1 that supports the razor head 2B. The razor head 2 </ b> B is lifted and urged by an elastic material including a pair of left and right springs 80 housed in the main body case 1 and supported in a floating manner. A retaining structure for retaining the razor head 2B against the urging force of the elastic material is provided between the razor head 2B and the main body case 1. The retaining structure includes a head-side engaging body 56 and a case-side engaging body 66 that allow the razor head 2B to descend and slide in contact with each other while allowing the razor head 2B to tilt left and right.

In the present invention, a pair of left and right springs 80 are mainly used, and the razor head 2B is pushed up and biased by these to support the floating, and the razor head is provided with a retaining structure provided between the razor head 2B and the main body case 1. 2B is retained against the urging force of the elastic material, so that the floating support structure is simplified compared to the conventional electric razor that floats and supports the razor unit with three support legs and springs and a spherical seat. In addition, the assembly work can be saved, and the manufacturing cost of the electric shaver can be reduced accordingly. The razor head 2B is pushed up and biased by a pair of left and right springs 80, and the razor head 2B is floated and supported in a rather unstable state, so that the razor head 2B can be smoothly tilted following changes in the skin surface and can be ignored. The frictional resistance can be reduced to a certain extent, and accordingly, the whisker cutting surface of the razor head can be followed in a state of being in close contact with the skin, and the whiskers can be cut effectively. The head side engaging body 56 and the case side engaging body 66 are in contact with each other and can hold the razor head 2 </ b> B against the urging force of the spring 80. Further, since the head side engaging body 56 and the case side engaging body 66 are engaged in contact with each other in a state in which the razor head 2B is allowed to slide downward and the razor head 2B is allowed to tilt left and right, the razor head 2B can be arbitrarily connected. By tilting left and right in the floating position, the whisker cut surface can be made to follow in a state of being always in close contact with the skin.

The tension body 46 can swing back and forth around the shaft 47 and is urged to swing counterclockwise by a spring 48, and the roller 49 at the front end circumscribes the timing belt 45 to adjust the tension.

  The motor base 22 is composed of a frame body having an upper surface surrounded by front and rear walls and left and right walls. As shown in FIGS. 8 and 9, a motor 19 and a motor holder 51 are fixed to the lower surface of the frame. The motor base 22 and the motor holder 51 sandwich and fix the inner peripheral edge 15a of the waterproof seal 15 up and down. The outer peripheral edge 15b of the waterproof seal 15 is fitted into a mounting groove 53 (see FIG. 10) provided on the outer peripheral surface of the inner seal wall 52 at the top of the inner frame 16. The outer peripheral surface of the fitting portion is in close contact with the inner surface of the seal wall 54 on the upper inner surface of the main body case 1 to seal between the main body case 1 and the inner frame 16. A pair of front and rear leg pieces 55 project from the lower portions on both sides of the motor base 22, and a projection (head-side engagement body) 56 made of a round shaft is formed on the outer surface of the projecting end. The function of the leg piece 55 will be described later.

  The motor holder 51 is a cylindrical frame-shaped case that opens upward. A pair of front and rear retaining leg pieces 57 are provided on the upper portions of the left and right side surfaces, and a spring seat 58 is provided between the two holding leg pieces 57. Project. An inner seal wall 52 for accommodating the motor holder 51 is provided around the upper portion of the inner frame 16, and a pair of front and rear receiving claws 59 corresponding to the holding leg piece 57 and the spring seat 58 on the left and right inner bottom walls are provided. A spring seat 60 is provided. With the compression coil spring (elastic material) 80 disposed between the upper and lower spring seats 58, 60, the motor holder 51 is assembled to the inner frame 16, so that the lower end claw of the holding leg piece 57 is received by the claw 59. And the razor head 2B is held against the electrical component unit 2A against the elasticity of the spring 80. In the state in which the operation unit 2 is incorporated in the main body case 1, the spring 80 is positioned within the area covered by the waterproof seal 15 as shown in FIG. 5, so that the squeak noise of the spring 80 can be reliably prevented from leaking outside the case.

  In order to partially regulate the floating operation of the razor head 2B, a switching mechanism is provided between the razor head 2B and the main body case 1. In FIG. 12, the switching mechanism includes a frame 62 disposed between the main body case 1 and the front cover 12, a slide knob 11 disposed on the front upper portion of the front cover 12, and a left / right sliding operation of the slide knob 11 to an up / down operation. A cam structure to be converted, and a pair of left and right leg pieces 55 provided on the motor base 22 to inherit the operation of the frame body 62 are included.

  In FIG. 13, the frame body 62 is formed of a stainless steel press fitting integrally provided with a pair of left and right arm portions 63 and a frame base portion 65 that connects the both arm portions 63 with each other through an inclined wall 64. Each arm portion 63 is provided with a vertically long oval groove (case side engagement body) 66 that engages with the protrusion 56 of the leg piece 55. A stepped cam portion 67 is formed at the center upper edge of the frame base portion 65, and a downward notch 68 is formed at the lower edge thereof.

  As shown in FIGS. 12 and 14, the frame body 62 is disposed along the outer opening edge of the seal wall 54 of the main body case 1 with the groove 66 of the arm portion 63 engaged with the protrusion 56 of the leg piece 55. The main body case 1 and the front cover 4 are slidably guided only in the vertical direction by the double wall. Specifically, the frame base portion 65 is sandwiched between the seal wall 54 of the main body case 1 and the guide portions 70 provided on the left and right of the upper wall portion of the front cover 4, and the frame base portion 65 moves vertically along the outer surface of the seal wall 54. Further, a pair of left and right ribs 71 (see FIG. 13) projecting from the outer surface of the seal wall 54 guide the vertical vertical edge of the notch 68, and the frame body 62 tilts left and right. Is regulated. When sliding up and down, the inclined wall 64 is received by the partial arc-shaped corner portions 72 located on both sides of the seal wall 54, which also helps to restrict the frame body 62 from tilting left and right. . As described above, when a part of the main body case 1 is constituted by a double wall and the projection 56 of the leg piece 55 and the groove 66 of the arm portion 63 are accommodated between the double walls, for example, an electric razor falls on the floor surface. In such a case, it is possible to reliably prevent the projection 56 that has received an impact from coming out of the groove 66 by the inner and outer walls.

  A switching mechanism is provided between the main body case 1 and the razor head 2B to switch the vertical position of the razor head 2B and change the reaction force of the razor head 2B by the spring 80 to a plurality of stages. The slide knob 11 provided on the outer surface of the main body case 1, the frame body 62 that is operated up and down by the slide knob 11, and the lower part of the motor base 22 that constitutes the razor head 2B are projected so as to lower the frame body 62. A pair of leg pieces 55 to be inherited is included, and the leg pieces 55 and the frame body 62 are connected to each other via a groove 66 that allows the razor head 2B to move up and down and a protrusion 56 that engages with the groove 66. The groove 66 also serves as the case-side engaging body.

  A switching mechanism is provided between the main body case 1 and the razor head 2B to change the pressing reaction force of the razor head 2B into a plurality of stages, and the projections 56 provided on the leg pieces 55 constituting the switching mechanism also serve as the head side engaging body. If the groove 66 provided in the frame body 62 also serves as the case-side engaging body, the structure can be simplified and the manufacturing cost of the electric razor can be reduced accordingly.

  Specifically, the slide knob 11 is supported so as to be slidable left and right along a slide groove 73 provided in the front cover 4. The cam structure includes a cylindrical roller 74 that is disposed on the inner surface of the slide knob 11 and is rotatably supported by a shaft, and a cam portion 67 provided on the previous frame base portion 65. The roller 74 is rotatably held by a claw 75 provided on the inner surface of the slide knob 11, and the stepped portion of the peripheral surface contacts the inner edge of the opening of the slide groove 73 so that the slide knob 11 cannot be removed. keeping. In a state where the slide knob 11 is assembled to the front cover 4, the peripheral surface of the roller 74 intersects with the cam portion 67 and is received by a guide recess 76 provided on the upper edge of the seal wall 54. That is, the slide knob 11 is guided and supported directly by the three of the front cover 4, the slide groove 73, and the guide recess 76 or indirectly via the roller 74.

  As shown in FIG. 12, in the normal state, the roller 74 is fitted into the lower step portion of the cam portion 67, and at this time, the protrusion 56 is positioned at the upper end of the groove 66. 15, when the slide knob 11 is slid to the right as shown in FIG. 15, the frame body 62 is pushed down against the urging force of the spring 80, and the upper step is received by the roller 74. It is held incapable of ascending. That is, the razor head 2B is switched from the floating position (the state shown in FIG. 2) in which the razor head can be fully floated to the restricted position (the state shown in FIG. 15) where the floating operation is restricted. Incidentally, the razor head 2B in this embodiment can move downward by about 4 mm in the floating position, but the lowering stroke is restricted to 1.5 mm in the restricted position. In a state where the razor head 2B is pushed in for the entire floating stroke, the spring 80 is fully compressed, so that the razor head 2B cannot be further lowered. At this time, the protrusion 56 is opposed to the lower end of the groove 66 with a slight gap.

  As described above, the razor head 2B can float up and down with respect to the main body case 1. When the razor head 2B moves up and down, the arm portion 63 of the frame body 62 slides and guides the outer surface of the leg piece 55, thereby moving the razor head 2B left and right. To regulate. Further, the groove 66 restricts the forward and backward movement of the protrusion 56, so that the vertical slide locus of the protrusion 56 is always constant. By forming the protrusion 56 with a round shaft and the groove 66 with an oblong groove, and securing a floating gap E1 between the front and back of the motor base 22 and the main body case 1, the razor head 2B is controlled to the floating position. It can be tilted back and forth as shown in FIG. Further, by securing a floating gap E2 between the leg piece 55 and the seal wall 54, the razor head 2B can be tilted left and right at an arbitrary vertical position as shown in FIG.

  The left and right leg pieces 55 are disposed on the left and right sides of the main body case 1, and the left and right distance between the leg pieces 55 is much larger than the left and right distance between the springs 80. Therefore, as shown in FIG. 1, for example, when the left end of the razor head 2B is pushed and sinks obliquely toward the main body case 1 with the right projection 55 as a fulcrum, the left spring 80 is of course the right spring 80. Is also compressed and deformed. Accordingly, at the same time as the external force is released, the posture of the razor head 2B can be immediately returned by the two springs 80. That is, the response speed when the razor head 2B returns to the floating position can be improved.

  In FIG. 4, the head frame 23 has a case portion 82 that opens downward, and side walls 83 that are erected on both left and right ends of the case portion 82, and the case portion 82 is joined and fixed to the motor base 22 in a cover-like manner. Thus, the first transmission chamber 27 is defined between the joint surfaces of the two 22 and 23. In this joined state, the side wall 83 and the partition wall 31 are flush with each other, and the second transmission chamber 28 is defined by both of them 31 and 83 and a cover 84 that is put on them. The cover 84 is detachably engaged with and fixed to the side wall 83.

  The inner blade support base 24 is composed of a base base 85 having a section that opens upward, a pair of left and right arms 86 erected from both left and right ends, and a lid 87 that closes the upper surface opening of the base base 85. By supporting the shaft provided at the upper part of the left and right arms 86 by the bearing 81 at the upper part of the side wall 83 of the head frame 23, the inner blade support base 24 can swing back and forth, that is, the entire shaving block 91 is It is pivotally supported with respect to the frame 23 so as to be able to swing. An inner blade frame 25 described later is detachably press-fitted and engaged between the pair of arms 86. Inside the pedestal base 85, there are provided a lock mechanism for locking the outer blade holder 26 that is externally fitted to the inner blade support base 24 so that it cannot be detached and a vibrator 39 for the center blade 38.

  The inner blade frame 25 has a base wall 88 and a pair of side walls 89 erected on both left and right ends of the base wall 88, and a pair of front and rear inner blades 20 are rotatably supported between the upper ends of both side walls 89. is doing. A small-diameter inner blade gear 30 is fixed to the left inner blade shaft toward FIG. 4, and this gear 30 meshes with a final gear 29 provided on the inner blade frame 25, so that the motor power can be reduced. The inner blade 20 is simultaneously transmitted. In order to clean the inner blades, a rotating brush 90 is arranged below each inner blade 20, and the left and right ends thereof are rotatably supported by slide pieces assembled to the side wall 89. The inner blade frame 25 is engaged and mounted on the inner blade support base 24 from above to constitute a shaving block 91. Note that the forward / backward tilt angle θ1 (see FIG. 7) of the shaving block 91 is set larger than the forward / backward tilt angle θ2 (see FIG. 16) with respect to the main body case 1 of the razor head 2B. The total tilt angle is set larger than the total tilt angle of the forward tilt angle θ2 of the razor head 2B with respect to the main body case 1 and the rear tilt angle θ2 ′. In summary, (θ1> θ2, θ1> θ2 ′) is satisfied, and the relationship (θ1 + θ1> θ2 + θ2 ′) is satisfied. The tension of the spring 92 (see FIG. 3) for returning and biasing the shaving block 91 is set smaller than the tension of the spring 80 for returning and biasing the razor head 2B. Incidentally, if the shaving block 91 can be tilted with a smaller force than the razor head 2B, it is not always necessary to urge the shaving block 91 with a spring, and the spring can be omitted. In this case, the position is held by friction between the bearing 81 of the head frame 23 and the shaft portion of the inner blade support 24 supported by the bearing 81.

  When the electric razor is used, the slide knob 11 is switched between the soft position and the hard position according to the state of the skin and the beard, and the pressing reaction force of the razor head 2B is set to either hard or soft. For example, when shaving is performed normally, the slide knob 11 is positioned in the soft position so that the razor head 2B can be fully floated, and the sinking of the razor head 2B is facilitated to facilitate close contact with the skin. In addition, when deepening, the slide knob 11 is slid to the hard position to increase the pushing-down reaction force of the razor head 2B, thereby enabling deepening. In the restricting position, the razor head 2B is held in a state where the spring 80 is half-compressed, so that the razor head 2B can be strongly pressed against the skin with a smaller pressing force, and as a result, the razor head 2B can be deepened. At this time, the lower end of the arm part 63 is received by the main body case so as not to be lowered.

  The razor head 2B can float up and down against the pushing force of the spring 80 and the waterproof seal 15 in both the floating position and the restriction position, and can tilt forward and backward and left and right. The razor head 2B is pushed up and biased mainly by two springs 80, and is a connecting portion between the head side engaging body (projection) 56 and the case side engaging body 66 (groove), that is, an arm portion of the frame body 62. 63 (connecting portion) prevents it from coming off. Therefore, when the razor head 2B is pushed in and the projection 56 and the upper end of the groove 66 are separated from each other, the razor head 2B is supported by only two springs 80, that is, in an extremely unstable state. Will be. Therefore, the razor head 2B can only tilt according to the external force, and as a result, the beard cutting surface can follow the skin smoothly.

  In the above-described embodiment, the projection 56 is contacted and engaged using the frame body 62 that restricts the floating operation of the razor head 2B, but this is not necessary, and corresponds to the arm portion (connecting portion) 63 of the frame body 62. The leg piece 55 can be engaged and held by mounting the member to be mounted on the main body case 1. The groove 66 can be integrally formed on the inner surface of the main body case 1. Of course, the case-side engaging body can be formed by the protrusion 56, and the head-side engaging body can be formed by the groove. That is, one of the head side engaging body and the case side engaging body can be formed by the protrusion 56 and the other can be formed by the groove 66 long in the vertical direction. The groove can be formed by a notch, a recess, a long hole-like boss, or a frame. In short, as long as the leg piece 55 and the frame 62 are connected while allowing the razor head 2B to move downward. Good. In the above embodiment, in the state where the razor head 2B is assembled to the electrical component unit 2A, the holding leg piece 57 is engaged with the receiving claw 59 in order to integrate the two inseparably, but it is not necessary. Depending on the shape of the motor base 22 and the main body case 1, the holding leg pieces 57 and the receiving claws 59 can be omitted. In this case, the protrusion 56 can be directly provided on the side surface of the motor base 22.

  In the above embodiment, since the slide knob 11 is supported by the front cover 4 so as to be slidable in the left and right directions, it is necessary to convert the left and right movements into vertical movements. Although the structure is provided, the cam structure can be omitted when the slide knob 11 is switched up and down. However, in this case, in order to hold the slide knob 11 in the restricted position, a position holding structure such as a joint mechanism or a position lock mechanism is added. In addition to sliding left and right or up and down, the slide knob 11 can be configured as a push button or a rotary dial.

  The cam portion 67 provided on the frame body 62 can be formed in a required number of stages, such as two or more stages, three stages, or four stages. In addition to the cam structure 63, the frame body 62 can be lowered by a swing lever. The present invention can also be applied to an electric razor having only one inner blade 9, an electric razor having a reciprocating inner blade, or an electric razor in which the inner blade rotates about the vertical axis. The inner blade support 24 and the inner blade frame 25 of the razor head 2B may be supported by the head frame 23 so as not to swing.
