Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an electric shaver having a feature of a lint discharge mechanism.

That is, in a configuration in which the hair waste is accumulated in the inner blade storage chamber and the hair waste is swept out from the inner blade storage chamber after the outer blade is removed, the hair waste discharge mechanism is troublesome.

Therefore, in this invention, during use, the hair waste is guided from the inner blade storage chamber to the hair waste introduction space communicating with this, and the hair waste can be collectively discharged to the outside from this hair waste introduction space.

[Conventional technology]

As a conventional technique regarding this type of hair waste discharge mechanism, for example, there is a technique as disclosed in Japanese Utility Model Application Laid-Open No. 52-89292. There, the entire inner bottom of the inner blade storage chamber serves as a lint tray that allows the drawer to be operated.
When discharging hair waste, the hair waste tray is rotated and pulled out of the razor body, and the hair waste is swept out from the hair waste tray.

[Problem that the invention attempts to solve]

However, in the conventional example mentioned above, in which the entire inner bottom of the inner blade storage chamber is a hair waste tray that can be pulled out and operated, when hair waste accumulates in the hair waste tray, the rotation of the inner blade is interrupted. Due to the air flow generated by this, hair debris may blow out from the hair introduction hole of the outer blade, causing problems such as irritation.

An object of the present invention is to provide an electric shaver equipped with a hair removal mechanism that can suppress the blowing of hair from the outer blade as much as possible.

[Means for solving problems]

In the present invention, as shown in FIGS. 1 and 6, for example, a lint introducing space 20 is formed below the inner bottom wall 7 of the inner cutter housing chamber 6 in which the inner cutter 12 is rotatably accommodated. This hair waste introduction space 20 is formed in an outwardly open shape and has an outer opening surface 21, and has a part of the inner bottom wall 7.
The hair waste introduction space 20 and the inside of the inner blade storage chamber 6 are communicated through a port 16 provided so as to face the outer opening surface 21.

A hair waste receiving tray 23 is installed in the hair waste introduction space 20 so as to be movable in and out between a position where the dish receptacle 23 enters and retreats into the space 20 and a position where it projects outward from the outer opening surface 21 of the space 20. The operation of moving the hair waste tray 23 in and out can be performed using an operation knob 36.

A guide wall 1 for leading out hair debris is provided at the mouth edge of the opening 16 of the inner cutter storage chamber 6 on the lower side in the rotational direction of the inner cutter.
7 is erected in the radial direction of the inner bottom wall 7 and below the inner cutter 12. Further, the outer opening surface 21 of the hair waste introduction space 20 is closed with a lid 35 so as to be openable and closable.

[Effect]

The hair waste receiving tray 23 is moved into the hair waste introduction space 20, and the outer opening surface 2 of the hair waste introduction space 20 is closed using the lid body 35.
When the inner cutter 12 is rotated in the closed state of the inner cutter 1, an air flow is generated in the inner cutter storage chamber 6, and this air flow P is guided to the passage 16 by the guide wall 17, and further as shown in FIG. The airflow hits the inner surface of the lid body 35 and goes around into the hair waste introduction space 20, and the hair waste is carried from the inner blade storage chamber 6 into the hair waste introduction space 20 and accumulated on the hair waste receiving tray 23. At this time,
The airflow that goes around into the hair waste introduction space 20 is caused by the inner bottom wall 7.
Since the hair is blocked by the lower surface side of the blade, the hair that accumulates in the hair and hair receiving tray 23 will not be thrown back into the inner blade storage chamber 6.

When discharging hair waste, as shown in FIG.
is opened, the hair waste receiving tray 23 is pushed outward from the outer opening surface 21 of the hair waste introducing space 20, and when the inner cutter 12 is rotated under this condition, the air flow P' generated by the rotation of the inner cutter is caused by the guide wall 17. Since the air flow P' is guided to the opening 16 and passes over the hair waste tray 23, the hair waste on the hair waste tray 23 is blown away to the outside together with the hair waste remaining in the inner blade storage chamber 6.

[Effect of idea]

According to the present invention, the hair waste introduction space 20 is formed below the inner bottom wall 7 of the inner blade storage chamber 6 and communicates with the inside of the inner blade storage chamber 6 through the opening 16, and the hair waste is placed in this space 29. In addition to incorporating the saucer 23 so that it can be moved in and out,
By closing the outer opening surface 21 of the hair waste introduction space 20 with the lid 35, the air flow generated by the rotation of the inner cutter 12 is introduced into the hole 16 by the guide wall 17 provided in the hole 16, and the hair is removed. It is assumed that it goes around into the waste introduction space 20. Therefore, the hair waste in the inner blade storage chamber 6 is carried onto the hair waste receiving tray 23 in the hair waste introduction space 20 by the air flow generated by the rotation of the inner blade, so that the hair waste in the inner blade storage chamber 6 is You can minimize the accumulation of debris, and you can also use the hair debris tray 2.
The hair debris carried on the outer blade 3 is less likely to fly back into the inner blade storage chamber 6, and this eliminates the problem of hair debris blowing out from the hair introduction hole of the outer blade 10 and scattering. I was able to resolve it.

In addition, when discharging hair waste, by opening the lid 35 and protruding the hair waste tray 23, the air flow generated by the rotation of the inner blade is used to remove the hair waste tray 23.
This is advantageous because the hair on the top is smoothly blown away together with the hair in the inner blade storage chamber 6, and the effort of brushing it off with a cleaning brush can be minimized.

〔Example〕

The drawings show an embodiment in which the present invention is applied to an electric shaver equipped with a rotary inner cutter.

In FIGS. 1 and 2, the razor body 1
has a built-in motor 2 in its upper part, and a head case 4 is fixed to the front of the upper part via a motor board 3.
The motor board 3 is integrally connected to the razor body 1,
The motor 2 is fixed inside the motor board 3 with two screws 5, 5 on the left and right. The inside of the head case 4 is an inner blade housing chamber 6, and the inner bottom wall 7 of the head case 4 is fixed to the motor board 3 with the screws 5, 5.

The head case 4 has a circular outer peripheral side wall 9 connected to the outer periphery of the inner bottom wall 7, and an outer cutter 10 is screwed into the outer peripheral side wall 9 via a holder 11 on the front surface of the opening. A holder 13 supporting the inner cutter 12 is accommodated in the inner cutter storage chamber 6 , and this inner cutter holder 13 is connected to the drive shaft 1 of the motor 2 .
5, and the inner cutter 12 rotates in elastic contact with the outer cutter 10.

At the upper part of the head case 4, an inner bottom wall 7 and an outer peripheral side wall 9 are provided.
A passage 16 is provided through the opening 16, and a guide wall 17 extending in the radial direction is provided protruding from the mouth edge of the passage 16 on the lower side in the rotational direction of the inner cutter.

The head case 4 has an inner bottom wall 7 formed into a raised bottom shape,
The upper front surface of the razor body 1, that is, the motor board 3
A gap 19 is provided between the inner bottom wall 7 and the inner bottom wall 7. The upper part of this gap 19 is set as a hair waste introduction space 20 that opens to the outside by cutting out the outer peripheral side wall 9 of the head case 4 over a constant width on the left and right sides. Hair waste introduction space 20
The upper end opening surface 21 is formed into a straight line by protruding the left and right opening edges of the outer peripheral side wall 9 outward.
An outward opening surface 22 of the passage 16 is continuous above the opening 1 .

A hair waste tray 23 is installed in the gap 19 so as to be slidable in the vertical direction. As shown in FIG. 6, the hair waste tray 23 has a passive portion 23b below the tray main body 23a, and the receiver main body 23a is located in the hair waste introduction space 20.

The passive part 23b of the hair receiving tray 23 has a through hole 25 in the center into which the motor drive shaft 15 is loosely fitted, and a length into which the insertion bosses 26 of the screws 5 protruding from the motor board 3 on the left and right are fitted. A hole 27 is provided transparently. In this way, the lint receiving tray 23 is prevented from rattling within the gap 19 by the fitting guidance between the boss 26 and the elongated hole 27 and the contact guidance between the left and right end surfaces of the tray main body 23a and the left and right opening end surfaces of the lint introducing space 20. It is slidably guided only in the vertical direction without any stickiness. Also,
The fitting between the boss 26 and the elongated hole 27 restricts the upward sliding limit of the hair receiving tray 23 from coming into contact with the downward sliding limit.

Furthermore, in order to eliminate back and forth play of the hair waste receiving tray 23 within the gap 19, a presser member is installed between the inner bottom wall 7 of the inner blade storage chamber 6 and the passive portion 23b of the hair waste receiving tray 23 at the center of the gap 19. 26 is attached. This presser member 29 is positioned on the inner bottom wall 7 side so as to be able to move back and forth while being prevented from rotating, and tongue-shaped presser portions 29a provided on the left and right sides of the presser member 29 are supported by compression coil springs 30, which are attached to the passive portion 23b. The lint receiving tray 23 is pressed against the motor board 3 side by elastically abutting the receiving surfaces formed on the left and right sides of the through hole 25, respectively. Each of the left and right receiving surfaces on the side of the passive portion 23b has a stepped stable receiving surface 31 and a protruding receiving surface 33 that continues below this via an inclined surface 32.

A lid 35 is provided as a means for sealingly closing the upper end opening surface 21 of the hair waste introduction space 20 and the outward opening surface 22 of the passage port 16 that is continuous thereto.
The illustrated lid body 35 is rotatably supported on the left and right sides of its base end on the motor board 3 side.

An operation knob 36 is provided for sliding the hair waste tray 23 in the vertical direction from the outside. This operation knob 36 is arranged on the left side of the outer peripheral side wall 9 of the head case 4, and can be slid from outside the case along the outer peripheral side wall 9 at a predetermined rotation angle. That is, a notch 37 is provided at a corresponding portion of the outer peripheral side wall 9 of the head case 4, and the operation knob 36 is inserted between the head case 4 and the motor board 3 via the notch 37, and the operation portion 36a of the operation knob 36 is inserted between the head case 4 and the motor board 3.
is slidably held along the outer circumferential side wall 9 in a state where it faces the outer surface of the outer circumferential side wall 9. As shown in FIGS. 2 and 3, a fork-shaped linking portion 38 is connected from the inside of the operating knob 36 to a pin 39 provided on the passive portion 23b of the hair receiving tray 23.

Next, I will explain the operation of the proposed lint discharge mechanism.
When shaving, as shown in FIG.
The opening surface 21 of 0 is hermetically closed. At this time, the operation knob 36 is located at the lower limit of the notch 37 of the head case 4 as shown by the solid line in FIG. (the upper end) is completely retracted into the hair waste introduction space 20 sealed by the lid body 35.
Then, the holding part 29a of the holding member 29 fits into the stable receiving surface 31 of the passive part 23b of the hair receiving tray 23 and is in elastic contact with it, so that the entire hair receiving tray 23 is unexpectedly slid upward. It is regulated to do so.

When shaving in this state, the hair cut by the inner blade 12 and the outer blade 10 will be removed from the inner blade storage chamber 6 through the opening 1.
6 into the hair waste introduction space 20 on the inner back side. At this time, due to the rotating air flow generated by the rotation of the inner cutter 12, the hair debris moving along the inner surface of the outer peripheral side wall 9 of the inner cutter storage chamber 6 is guided by the guide wall 17 and smoothly flows into the passage 16. Go. The hair waste introduced into the hair waste introduction space 20 is blocked by the inner bottom wall 7, as shown in FIG. 7, and is not blown back to the inner blade storage chamber 6 side. Therefore, the hair waste is received by the receiving tray body portion 23a of the hair waste receiving tray 23.

When discharging hair waste, the operating knob 36 is rotated to the upper limit of the notch 37 as shown in FIG. The operation knob 36 is generally operated with one hand using the thumb of the left hand that grips the razor body 1. This causes the hair receptacle 23 to slide upward via the linking portion 38 and the pin 39, and the upper half of the receptacle main body 23a protrudes outside the case. At this time, the lid 35 is pushed open. At this time, the holding portion 29a of the holding member 29 relatively moves from the above-mentioned stable receiving surface 31 over the inclined surface 32 and onto the protruding receiving surface 33, and the saucer main body portion 23a maintains the protruding state. When the inner blade 12 is rotated with the tray main body 23a protruding outward from the case, the rotating air flow generated in the inner storage chamber 6 is rectified in the radial direction by the guide wall 17 as shown by the arrow P'. Air flow is through port 1
6 onto the tray main body 23a.
As a result, the hair on the tray body 23a is blown out of the case without being scattered in the circumferential direction, and the hair can be easily discharged. Further, if necessary, the hair remaining on the tray main body 23a is swept out with a brush or the like.

When the hair removal work is completed, the operating knob 36 is rotated back to its original lower limit. At this time, the holding part 29a of the holding member 29 moves relatively on the inclined surface 32 as shown in FIG. 5, and slides down onto the stable receiving surface 31.
To effectively prevent a defective retraction state of a hair waste receiving tray 23.
Finally, the lid body 35 is returned to its original closed state. As shown in FIG. 5, the lid body 35 whose base end is pivotally supported has a convex portion 40 and a concave portion 41 on the outer peripheral side wall 9 of the head case 4 on the distal end side.
It is well maintained in the closed position by the convex-concave fitting.

[Another embodiment example]

In the illustrated example, the head case 4 is located at the upper front of the razor body 1, but the razor body 1
It goes without saying that the head case 4 may be located directly above the head case 4, and in that case, the hair waste tray 23 may be slid in a horizontal position.

The hair waste receiving tray 23 is disposed in the hair waste introduction space 20 formed between the inner bottom wall 7 of the inner blade storage chamber 6 and the corresponding wall member, and the illustrated motor board 3 is placed here. This is just one example of the wall member mentioned above.

The operation knob 36 is not limited to a configuration in which it is disposed on the outer peripheral side wall 9 of the head case 7, but also includes a configuration in which the operation knob 36 is linearly slidable and the hair waste tray 23 is rotated accordingly. . Depending on these forms, the means for interlocking and connecting the operating knob 36 and the hair waste tray 23 may also be changed in various ways.

As a means for closing the opening surface 21 of the hair waste introduction space 20, a lid body 35 as shown in the figure is pivotally connected to the razor body 1 side or the head case 4 side so as to be able to open and close, and can be rotated to close and close using a spring member. It may be biased, or a lid body 35 may be integrally connected to the tip of the hair waste receiving tray 23.
