Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric razor in which an outer blade holder is connected to a razor head so that the outer surface of the inner blade is released while swinging or can be brought into close contact with the inner blade.
[0002]
[Prior art]
This type of electric shaver is known from JP-A 63-82694. There, slide frames that protrude vertically are provided on the left and right sides of the main body case. The outer blade holder is supported by one slide frame so that it can swing up and down via a hinge. is doing. Each of the pair of slide frames is urged upward by a spring and is held on standby in a state of being retracted into the main body case. When the lock release buttons on both sides of the case are pushed in this state, both slide frames are slid upward and push the outer blade holder up to a position where it does not contact and interfere with the inner blade. Further, when the release button provided on one slide frame is pushed in, the outer blade holder swings upward and swings around the hinge center. In this state, the inner blade is washed with water.
[0003]
In the above-mentioned electric razor, the hinge center axis is provided on one side of the main body case in parallel with the front and rear center axis, and the outer blade holder swings open toward one side of the main body case. Japanese Utility Model Laid-Open No. 4-108070 discloses an electric razor in which an axis is provided in parallel with a case center axis and an outer blade holder is opened and swung in the front-rear direction. However, this electric razor is provided with a brush on the inner surface of the outer blade holder on the swinging tip side so that the dust attached to the inner blade can be cleaned by opening and closing the outer blade holder. Only it is.
[0004]
[Problems to be solved by the invention]
In the former electric razor, since the outer blade holder is supported by the pair of left and right slide frames, extra parts such as a slide frame, a spring, and a hinge are indispensable, and the structure is complicated and the cost increases accordingly. Since the outer blade holder swings open to one side, for example, when a side frame that supports the swing head is provided on both sides of the outer blade holder, such as a swing-type electric razor. The outer frame holder may not be able to open and swing sideways because the side frame becomes an obstacle, and there is a disadvantage that the application target is limited.
[0005]
In this regard, like the latter electric razor, when the outer blade holder is opened and swung in the front-rear direction, it can be applied to a swing-type electric razor. However, since the outer blade holder is only supported so as to be able to swing back and forth via a hinge, the swing angle of the outer blade holder cannot be increased, and the outer blade holder is an obstacle when washing with water. Therefore, there is an inconvenience that water must be poured from the front side to the inner blade. The shape and structure of the outer blade holder must be specialized.
[0006]
An object of the present invention is to provide an electric razor in which an outer blade holder is connected to a razor head, and when necessary, the outer blade holder can be opened and swung to greatly open the outer surface of the inner blade. . Another object of the present invention is to provide an electric razor in which the outer blade holder can be removed from the razor head as required, and for example, the outer blade can be replaced or the outer blade can be independently cleaned. Another object of the present invention is to provide an electric razor that can cause intermittent and irregular impacts on the razor head due to the impact impact of the fluid on the outer blade holder that has been rocked open, thereby improving the cleaning effect during cleaning. It is to provide.
[0007]
[Means for Solving the Problems]
In the electric razor according to the present invention, the outer blade holder 25 provided on the razor head 6 is supported so as to be swingable in the front-rear direction around the axis in the left-right direction provided on one of the front and rear surfaces of the razor head 6. It is. The outer blade holder 25 and the razor head 6 are connected so as to be swingable through a vertical groove 41 provided in any one of them and a shaft body 42 that slides relative to the groove 41. The outer blade holder 25 is swung around the shaft body 42, the use position where the outer blade holder 25 is fitted to the mounting portion 38 of the razor head 6, the swing standby position separated from the mounting portion 38 and slid upward. It is characterized in that it can be displaced to an open position where the outer surface of the inner blade 23 is opened.
[0008]
Between the mounting portion 38 of the razor head 6 and the outer blade holder 25, a lock body 51 that engages and holds the outer blade holder 25 in the use position is provided.
[0009]
The groove 41 and the shaft body 42 are configured to be relatively slidable and relatively rotatable.
[0010]
A connection port 43 that allows the shaft body 42 to enter and exit is provided in a part of the peripheral wall of the groove 41.
[0011]
A pair of left and right guide frames 40 defining a groove 41 is provided in the razor head 6, and a pair of left and right shaft bodies 42 are provided in the outer blade holder 25.
[0012]
The outer blade holder 25 in the open position is reversed from the mounting posture in the use position.
[0013]
A vertical groove 41 is provided in the razor head 6. A connecting port 43 that allows the shaft body 42 to enter and exit is provided on the peripheral wall of the groove 41 between the use position and the swing standby position.
[0014]
A vertical groove 41 is provided in the razor head 6. A connection port 43 that allows the shaft body 42 to enter and exit is provided on the peripheral wall of the groove 41 below the use position.
[0015]
In an electric razor in which the razor head 6 is pivotally supported by a pair of left and right side frames 5 provided on the side of the main body case 1 via a shaft 28, the outer blade holder 25 swings at the swing standby position. The center is disposed below the shaft 28.
[0016]
The groove width of the groove 41 is set smaller than the diameter dimension of the shaft body 42 in the vicinity of the connection port 43.
[0017]
A protrusion 53 is provided above the connection port 43 so as to receive the outer blade holder 25 that has been swung open and prevent the outer blade holder 25 from coming off due to its own weight.
[0018]
A holding portion 44 that prevents the shaft body 42 from slipping out is provided at the lower end of the groove 41.
[0019]
[Operation and effect of the invention]
The outer blade holder 25 is connected to the razor head 6 through the groove 41 and the shaft body 42, and after the outer blade holder 25 is slid upward, the outer blade holder 25 swings in an inverted manner. It can be opened. Therefore, for example, in the case of washing with water, running water can be poured on the inner blade 23 from either side of the front and rear surfaces, and thereby the debris adhering to the inner blade 23 and its periphery can be washed away to every corner. it can. The cleaning of the inner blade 23 and the like can be performed not only by using a cleaning brush but also by blowing compressed air or using a vacuum cleaner. Compared to a conventional electric razor in which the slide frame is pushed up to open and swing the outer blade holder, the manufacturing cost of the electric razor can be reduced by reducing the number of parts.
[0020]
The lock body 51 provided between the outer blade holder 25 and the mounting portion 38 prevents the outer blade holder 25 from being slid and displaced in the direction in which it floats away from the inner blade 23 when using a razor. It is provided to keep it in the proper use position.
[0021]
If the groove 41 and the shaft body 42 are configured to be relatively slidable and relatively rotatable, the outer blade holder 25 can swing relative to the razor head 6 at an arbitrary sliding position. The blade holder 25 can be supported by hanging freely. Therefore, when flowing water is poured onto the outer blade holder 25 or compressed air is blown, the outer blade holder 25 can be intermittently and irregularly shaken by the contact impact action, and the outer blade holder 25 at this time The cleaning effect of the razor head 6 and the outer blade holder 25 can be improved by the contact impact with the vibration and the razor head 6.
[0022]
When the shaft body 42 and the groove 41 are engaged and connected via a connection port 43 provided in a part of the peripheral wall of the groove 41, the outer blade holder 25 can be easily attached to and detached from the razor head 6, so that the razor Only the outer blade holder 25 separated from the head 6 can be separately cleaned, or the outer blade 26 can be easily replaced. For example, it is convenient to clean the outer blade holder 25 and the inner blade 23 separated from the razor head 6 with an ultrasonic cleaner.
[0023]
When the groove 41 is formed on the razor head 6 side, the groove 41 can be formed integrally with the components of the razor head 6, so that the number of parts can be prevented from increasing and the structural strength of the guide frame 40 that defines the groove 41 can be increased. Can be strengthened. In an electric razor in which the outer blade holder 25 in the open position is inverted and swung with reference to the mounting posture in the use position, the front and rear surfaces of the fuzz chamber 37 can be fully opened. It is possible to cleanly wash away or blow away fuzz and sebum adhering to the corners. Moreover, as shown in FIG. 16, it is convenient to dry the washed electric shaver by using the outer blade holder 25 that is reversed and swung as a stand.
[0024]
According to the connection structure in which the connection port 43 is provided in the middle of the groove 41 in the vertical direction, the outer blade holder 25 at the use position is operated to slide up and down, and after swinging open, unless the slide operation is performed in that state. The groove 41 and the shaft body 42 cannot be separated. That is, the outer blade holder 25 cannot be removed from the razor head 6 unless the user has a clear intention. Similarly, when the connection port 43 is provided below the use position, the outer blade holder 25 cannot be removed unless a series of operation procedures are similarly performed.
[0025]
The outer blade holder 25 that swings back and forth can be applied to a swing-type electric razor without any trouble. At this time, if the swing center of the outer blade holder 25 is disposed below the shaft 28 which is the swing center of the razor head 6, the gravity moment of the razor head 6 and the outer blade holder 25 and the outer blade holder 25 are affected. As shown in FIG. 14, the razor head 6 at the time of washing is always tilted in a certain direction according to the falling moment of the flowing water, and the inner bottom surface of the fluff chamber 37 is inclined with respect to the falling direction of the flowing water. Can be directly impacted. Therefore, even when a sebum mass that is hard to fall off adheres to the bottom surface of the fuzz chamber 37 or the like, it can be washed out reliably and easily.
[0026]
The reason why the groove width of the groove 41 is set smaller than the diameter of the shaft body 42 in the vicinity of the connection port 43 is to prevent the outer blade holder 25 that has been oscillated open from floating out of the connection port 43 during cleaning or the like. In order to prevent the outer blade holder 25 from being removed from the razor head 6 unless there is a clear intention of the user.
[0027]
The reason why the protrusion 53 is provided above the connection port 43 is to prevent the outer blade holder 25 from coming off due to its own weight as described above. In addition, the protrusion 53 in this case can be shared by the lock body 51 described above.
[0028]
The holding portion 44 provided at the lower end of the groove 41 prevents the shaft body 42 provided on the outer blade holder 25 from moving in the front-rear direction at the use position where the outer blade holder 25 is fitted to the mounting portion 38. Thus, the outer blade holder 25 can be stably maintained in an appropriate mounting state.
[0029]

It is transmitted to the blade unit 14 and the inner blade 23.
[0031]
8 to 10, the razor head 6 is used for an inner blade in a chamber surrounded by the frame 20 and the lid 21, with an inverted portal frame 20 and a lid 21 screwed to the frame 20 as an attachment base. The vibrator 18 and a lock mechanism for the outer blade holder 25 are incorporated, and the inner blade 23 is detachably press-fitted to the pair of front and rear drive shafts 22 protruding from the upper surface of the lid 21. On the pair of front and rear drive shafts 22, a drive piece 24 that moves along with these is fitted and fixed. The outer blade holder 25 fitted to the frame 20 is provided with a pair of front and rear outer blades 26 corresponding to the previous inner blade 23, and a center trimmer 27 that is reciprocated by the previous drive piece 24. The shaft 28 fixed to the outer surfaces of the pair of left and right side walls of the frame 20 is supported by the head frame 4 so that the entire razor head 6 can swing in the front-rear direction. In order to enable power transmission during swinging, the passive groove of the previous vibrator 18 is curved in a partial arc shape (see FIG. 10).
[0032]
In order to lock the razor head 6 so as not to swing, a lock knob 30 and a lock bar 31 that slide up and down are provided on one side of the head frame 4 as shown in FIG. The razor head 6 can be locked and fixed in a state where the lock recess 32 is engaged.
[0033]
The outer blade holder 25 has a holder frame 35 having upper and lower walls that have front and rear walls and left and right side walls. The center trimmer 27 and the reinforcing frame 36 are attached to the front and rear centers of the inner surface of the holder frame 35. The front and rear walls 26 and the reinforcing frame 36 hold the front and rear outer blades 26 in a cross-sectional arch shape. In a state where the outer blade holder 25 is fitted to the razor head 6, the front and rear walls thereof are fitted on the stepped mounting portions 38 provided on the front and rear surfaces of the frame 20, and are received so as not to be able to move back and forth. The frame 20 is received on the inner surface of the side wall so that it cannot move left and right. Between the outer blade holder 25 and the frame 20 in this state, a fluff chamber 37 for accommodating the fluff cut by the inner blade 23 is defined (see FIG. 10).
[0034]
The outer blade holder 25 is connected to the razor head 6 so as to be open and swingable in the front-rear direction, so that the outer surface of the inner blade 23 can be largely opened during washing. Therefore, as shown in FIG. 11, a pair of left and right guide frames 40 are integrally formed on both sides of the rear surface of the lid body 21, and upper and lower grooves 41 partitioned by the guide frames 40 are used to form both sides of the lower end of the rear wall of the holder frame 35. The shaft 42 projecting from the guide is supported so as to slide up and down. In FIG. 1, a connection port 43 that allows the shaft body 42 to be taken in and out is provided near the lower end of the guide frame 40, and a frame portion below the connection port 43 serves as a holding portion 44. The upper and lower gaps of the connection port 43 are set slightly smaller than the diameter dimension of the shaft body 42.
[0035]
As described above, the shaft 42 provided on the holder frame 35 is slidably guided by the groove 41, so that the holder frame 35 is fitted into the mounting portion 38, and at the same time the outer blade 26 is 23, the use position (state shown in FIG. 10) close to the head 23, the swinging standby position (state shown in FIG. 1) where the entire outer blade holder 25 slides upward and separated from the mounting portion 38 and the inner blade 23, and the outer The blade holder 25 can be displaced to an open position (state shown in FIG. 14) in which the front and rear surfaces of the inner blade 23 and the fluff chamber 37 are completely opened by swinging reversely to the razor rear surface side around the shaft body 42. The outer blade holder 25 is once slid upward to the swing standby position to avoid the holder frame 35 from contacting and interfering with the inner blade 23 during the open swing and further separating the center trimmer 27 and the drive piece 24 from each other. It is to do.
[0036]
In order to lock and hold the outer blade holder 25 fitted to the mounting portion 38, a lock mechanism shown in FIG. 12 is provided. The locking mechanism includes a lock release button 46 attached to one side frame 5 of the head frame 4, a lock piece 47 incorporated in the frame 20, a pair of left and right compression coil springs 48, and the front and rear of the holder frame 35. It comprises an engaging recess 49 provided on the inner surface of the wall. In FIG. 6, the lock piece 47 includes a horizontally long rod-shaped core shaft 50 provided at the front and rear center, a pair of left and right lock bodies 51 protruding from the front and rear walls of the mounting portion 38, and the core shaft 50 and the lock body 51. It consists of a plastic molded product integrally formed with four hinge portions 52 to be connected, and a spring 48 is interposed between the lock bodies 51 and 51 that make a pair in the front and rear, and the lock bodies 51 and 51 are forward and backward. Energize to advance toward. One end of the core shaft 50 is slidably guided and supported by one side wall of the frame 20, and the shaft end faces the button 46. Accordingly, when the button 46 is pushed in, the core shaft 50 moves in the middle right direction in FIG. 12, and each lock body 51 is retracted into the frame while resisting the urging force of the spring 48. 49 is released.
[0037]
The electric shaver configured as described above is washed with water as shown in FIGS. Prior to cleaning, the button 46 is pushed in to release the engagement state between the lock body 51 and the engagement recess 49. By this unlocking operation, the entire outer blade holder 25 is displaced upward by several mm by a spring that pushes up and biases the inner blade 23. In this state, when the outer blade holder 25 is slid upward along the groove 41 to the swing standby position, the shaft body 42 is received by the upper end of the groove 41, so that the outer blade holder 25 is continuously swung in the reverse direction to the razor. The front and rear surfaces of the inner blade 23 can be opened by moving the operation.
[0038]
By pouring running water over the opened inner blade 23 and the fluff chamber 37, the fluff and sebum adhering to them can be washed away cleanly. At this time, since the shaft body 42 of the outer blade holder 25 is located below the position of the shaft 28 of the razor head 6, the razor head 6 is caused by the gravitational moment between the own weight and the outer blade holder 25. Inclined so that the inner bottom surface is slightly upward. Accordingly, it is not necessary to incline the razor head 6 in particular, and the running water can be directly collided with the inner bottom surface and the corners. Further, by pouring the running water on the inner surface of the outer blade holder 25 which is inverted, the outer blade holder 25 can be vibrated intermittently and irregularly, or the holder frame 35 can be caused to collide with the frame 20. Further, the entire razor head 6 can be rattled by an impact force at the time of a collision, and sebum masses and debris adhering to the inner blade 23 and the debris chamber 37 can be shaken off.
[0039]
When water is poured from the rear side of the razor, as shown in FIG. 15, the outer blade holder 25 is pressed and held by the fingertips, and then the running water is poured to a necessary portion. If necessary, the shaft body 42 of the outer blade holder 25 may be extracted from the connection port 43 and separated from the razor head 6, and only the outer blade holder 25 may be separately cleaned. After the cleaning, the electric razor can be effectively dried by leaving the outer blade holder 25 that is inverted and swung as a stand as shown in FIG. 16 to allow the water droplets attached to the razor head 6 and the outer blade holder 25 to be effectively dried. .
[0040]
The lock body 51 also serves as a protrusion 53 for preventing the outer blade holder 25 that has been opened and oscillated at the oscillation standby position from sliding along the groove 41 due to its own weight and falling off from the connection port 43 (FIG. 11). In order to avoid the contact interference with the projection 53 (lock body 51) and operate the outer blade holder 25 to be pulled out without hindrance, a relief groove 54 is formed below the engaging recess 49 (see FIG. 1). . That is, depending on the opening angle of the outer blade holder 25 (when sliding with the opening angle of the outer blade holder 25 shown by the dotted line in FIG. 1), the contact is interfered by the projection 53 and the slide is regulated. Thus, if an angle is intentionally generated, interference can be avoided, the slide can be smoothly performed downward, and the outer blade holder 25 can be removed. Of course, since the protrusion 53 also serves as the lock body 51 and is provided so as to be retractable, if the outer blade holder 25 is pushed down strongly, it can slide downward at any angle. In a state where the outer blade holder 25 is fitted to the mounting portion 38, the shaft body 42 is received and held by the holding portion 44 at the lower end of the guide frame 40 as shown in FIG. 10. Therefore, even when an external force is applied to the holder frame 35 due to a drop impact or the like, the front and rear walls are prevented from moving away from the mounting portion 38, and the outer blade holder 25 is maintained in an appropriate mounting state. You can continue.
[0041]
Next, another embodiment in which the connection structure between the outer blade holder 25 and the razor head 6 is changed will be described. In FIG. 17, the entire length of the groove 41 is extended downward from the position of the shaft body 42 at the use position, and the connection port 43 is provided on the peripheral wall of the groove 41 below the use position. Further, in order to prevent the outer blade holder 25 that has been rocked open from coming out of the connection port 43 due to its own weight, the guide frame 40 is bent inwardly in the vicinity of the connection port 43, and the groove of the groove 41 in that portion is formed. The width was set smaller than the diameter dimension of the shaft body 42. When completely removing the outer blade holder 25, the shaft body 42 is pushed down against the elastic pressure of the guide frame 40 and is extracted from the connection port 43.
[0042]
In FIG. 18, a pair of slide arms 56 protrudes from the holder frame 35, and grooves 41 are formed in each of the opposing surfaces of both arms 56. Correspondingly, a pair of left and right brackets 57 project from the frame 20 side, and a shaft body 42 that slides and guides the groove 41 is projected from the outer surface of each bracket 57. Thus, the groove 41 and the shaft body 42 can be provided on either side of the razor head 6 and the outer blade holder 25. In this case, the groove 41 can be engaged with the shaft body 42 by elastically deforming the pair of slide arms 56 in the left and right direction. That is, the connection port 43 can be omitted.
[0043]
The groove 41 and the shaft body 42 can be provided together on the razor head 6 side. For example, as shown in FIG. 19, the shaft body 42 can be slid up and down in the groove 41 but cannot be detached, and the outer blade holder 25 is connected to the shaft body 42 protruding out of the groove. .
[0044]
As shown in FIG. 20, the connection port 43 can be formed on the upper front side of the guide frame 40. In this case, since the connection port 43 is not on the rear surface side, it is possible to prevent the outer blade holder 25 from coming off due to its own weight as much as possible during cleaning in the open state.
[0045]
In addition to the above-described embodiments, the present invention can be applied to a normal type electric shaver that is not a swing type, and a rotary electric shaver in which an inner blade is rotatably supported around a horizontal axis. Further, the present invention is equally applicable to an electric razor not provided with a center trimmer and an electric razor provided with only one inner blade 23.
