A hair receiving tray 8 having a hair collecting chamber 7 is fixed to the upper surface of the motor mount 6, and the motor 2 is attached from the center of the hair receiving tray 8.
The shaft 9 of is projected forward. A drive shaft 10 is attached to the shaft 9 of the motor 2, and a holder 12 of an inner blade 11 is detachably connected to the drive shaft 10.

The holder 15 of the outer blade 14 is detachably screwed into the outer periphery of the open end of the peripheral wall 13 of the bristle tray 8.

A power switch 16 is housed inside the grip portion 4 of the main body case 1, and a switch operating piece 17 that is integrally coupled with the switch operating knob 5 and slides vertically along the inner wall of the case is housed. The piece 17
The ON / OFF state of the power switch 16 can be obtained by sliding up and down.

The switch operating knob 5 is vertically slidable integrally with the switch operating piece 17 on the front surface of the grip portion 4 of the main body case 1, and is turned on in its raised position and turned off in its lowered position. Is set.

A hair waste discharging mechanism is incorporated in the hair storage chamber 7. With respect to the mechanism, as shown in FIG. 1, a hair waste outlet 18 is opened in a part of the circumference of the peripheral wall 13 of the hair receiving tray 8 so as to communicate with the hair storage chamber 7. Further, a shutter mechanism 19 for opening and closing the hair waste outlet 18 is attached to the hair receiving tray 8. The shutter mechanism 19 is formed by fitting a shutter ring 21 having a lint discharge port 20 on the outer periphery of the bristle tray 8 so as to be rotatable in the circumferential direction. An operating knob 22 is integrally connected to a lower outer peripheral portion of the shutter ring 21 so as to extend outward in the radial direction, and the operating knob 22 is provided on the front surface of the grip portion 4 as shown in FIG. At a position facing the switch operation knob 5, that is, at a closed position, the dust discharge port 18 of the hair storage chamber 7 is closed by the blind wall portion of the peripheral wall of the shutter ring 21. When the operation knob 22 is rotated in the direction of arrow A in FIG. 1 and protrudes outward from the side edge 4b of the front surface 4a of the grip portion 4 as shown in FIG. The waste dust outlet 18 of No. 7 is opened in conformity with the communication state of the waste dust outlet 20 of the shutter ring 21.

In FIGS. 1 and 4, a rotary impeller 24 for sweeping away dust is provided in the hair collecting chamber 7 so as to be disposed below the inner blade 11. The rotary impeller 24 has a plurality of blades 25 and is rotatably supported in the hair-holding chamber 7 around the drive shaft 10. The impeller 24 is transmitted to the inner blade holder 12 via a clutch mechanism 26. Be connected. The clutch mechanism 26
Is a rotating plate 27 which is arranged below the bristle tray 8 in the diameter direction thereof and which is integrally coupled to the shutter ring 21 and rotates around the drive shaft 10, and is integrated with the rotary plate 27 on the drive shaft 10. Drive shaft 10 is coupled to the drive shaft 10 as the rotary plate 27 rotates.
And a clutch piece 28 that moves up and down along. The clutch piece 28 is engaged and disengaged with the coupling claw 29 at the lower end of the inner blade holder 12 with this vertical movement. Thus, when the shutter ring 21 is at the position (see FIG. 1) that closes the shavings discharge port 18, the clutch piece 28 is in a state of being disengaged from the inner blade holder 12 as shown in FIG. Therefore, the drive shaft 10 drives only the inner blade 11, and the rotary impeller 24 is in a stationary state. When the shutter ring 21 is rotated to a position (see FIG. 2) in which the waste dust outlet 18 is opened, the rotary plate 27 rotates with the rotation.
As a result, the clutch piece 28 slides upward along the drive shaft 10 and engages with the coupling claw 29 of the inner blade holder 12, and at this time, the drive blade 10 drives the inner blade 11 and at the same time the rotary impeller 24. Is driven via the clutch piece 28.

A shutter lock means 30 is provided between the switch operation knob 5 and the shutter mechanism 19. As shown in FIG. 2, this shutter lock means 30 releases the operation lock of the shutter mechanism 19 when the switch operating knob 5 is at the setting position where the power switch 16 is turned off, and the shutter mechanism 19 removes the lint discharge port 18. Can be opened and closed,
The switch operating knob 5 can be operated to the setting position for turning on the power switch 16 only when the waste mechanism 18 is closed and opened by the shutter mechanism 19. The content is that the operation of the shutter mechanism 19 is locked and the opening and closing of the lint discharge port 18 is disabled when the power switch 16 is in the set position.

The shutter lock means 30 is configured by using the operation knob 22 of the shutter ring 21 and the switch operation knob 5. That is, the shutter ring 2
1 is provided with a recessed notch 31 at the lower edge and the switch operation knob 5 is provided at the upper edge with a lock claw 32 corresponding to the recessed portion 31, and the switch operation knob 5 is provided as shown in FIG. When the is in the ON position, the lock claw 32
The shutter ring 21 is engaged in the recessed portion 31 of the operating knob 22 in the closed state, and by this engagement, the shutter ring 21 is closed and locked, and rotation of the shutter ring 21 toward the open position is restricted. As shown in FIG. 2, the switch operation knob 5
Is in the off position, the lock claw 32 of the knob 5 is
The shutter ring 21 can be opened / closed and rotated by the operation knob 22 because the shutter ring 21 is pulled out from the recess 31 of the operation knob 22 of the shutter ring 21. Therefore, when the shaving use state of FIG. 1 is changed to the dust removal state, the switch operating knob 5 is set to the off position as shown in FIG. 2, and the shutter ring 21 is first rotated to the open position. The switch operation knob 5 is slid to the on position to switch it on, and the rotary impeller 24 that rotates together with the inner blade 11 discharges the shavings in the hair collecting chamber 7 to the shaving discharging port 18. As shown in FIG. 2, the switch operating knob 5 in the OFF position abuts and interferes with the operating knob 22 and cannot be slid to the ON position unless the lint outlet 18 is opened. Therefore, it is not possible to open the shaving discharge port 18 with the power switch 16 of the motor 2 turned on, and open the shaving discharge port 18 in advance to determine the location of the shaving discharge and prepare for it. The procedure for turning on the power switch 16 will be followed.

To return from the shavings cleaning state to the normal shaving state, after returning the switch operating knob 5 to the prescribed off position again, the shutter ring 21 is rotated to the closed position to close the shaving discharge port 18, and The switch operation knob 5 is slid to the on position and the inner blade 11 is rotated by driving the motor 2. In this case, the switch operation knob 5 at the on position is the operation knob 2 of the shutter ring 21.
The shutter ring 21 is prevented from being opened by careless handling because it is engaged with 2.

[Another embodiment]

5 to 7 show another embodiment of the present invention.
This embodiment shows another modified example of the shutter ring 21 and the shutter lock means 30. The shutter ring 21 has a lint discharge port 20 and is rotatably mounted on the outer periphery of the bristle tray 8. However, the shutter ring 21 does not have the operation knob 22 as in the above-described embodiment, but is the same as that of the above-described embodiment, and the waste dust outlet 2 is not provided.
0 is provided so as to project from a part of the peripheral surface of the shutter ring 21, and a finger can be directly hung on the projecting wall surface of the trash discharge port 20 to perform its rotating operation. . As the shutter lock means 30, the switch operation knob 5 provided on the front surface of the grip portion 4 of the main body case 1 so as to be vertically slidable between the on position and the off position is provided with the lock claw 32, while the shutter ring 2 is provided.
On one part of the peripheral wall 13 of the first concave portion 31a, 31b with which the locking claw 32 is engaged and disengaged are arranged side by side in the circumferential direction.

Thus, as shown in FIGS. 5 to 7, when the switch operating knob 5 is slid to the on position when the shutter ring 21 is in the closed position, the lock claw 32 thereof engages with the recess 31a of the shutter ring 21. The shutter ring 21 is prevented from opening and rotating. When the switch operating knob 5 is in the off position as shown in FIG.
Allows the shutter ring 21 to open and rotate by slipping out of the recessed portion 31a of the shutter ring 21. Further, when the shutter ring 21 shown in FIG. 6 is opened and the switch is turned on for cleaning, the lock claw 32 of the switch operation knob 5 is allowed to slide upward to the ON position so that the lock claw 32 has a concave portion adjacent to the concave portion 31a. Insert into the cutout 31b.

Further, in the present invention, the shutter mechanism 19 is not limited to the shutter ring 21 having a ring shape surrounding the entire circumference of the bristle tray 8, but in addition to that, for example, the waste debris outlet 18 of the bristle tray 8 can be closed. For example, a shutter plate having a flat size may be used.

Further, as the shutter lock means 30, instead of the above-described embodiment in which the switch operating knob 5 is directly engaged with and disengaged from the shutter ring 21 or its operating knob 22, for example, in addition to the switch operating knob 5 and the shutter. A lock member separate from them is arranged between the ring 21 and the ring 21, and the lock member is locked / unlocked with respect to the shutter ring 21 in conjunction with the on / off operation of the switch operation knob 5 by a slide switch or a push button switch. It may be locked.

Further, in the present invention, the rotary impeller 24 described above is not always necessary.

[Effect of device]

According to the present invention, the switch operation knob 5 cannot be operated to the set position for turning on the power switch 16 unless the shutter mechanism 19 completely closes the waste chip outlet 18 during shaving. Moreover, as long as the switch operating knob 5 is in the ON position, the operation lock of the shutter mechanism 19 does not work, and the lint discharge port 18 does not open accidentally. Therefore, when the shaving is used, it is possible to well prevent the shaving discharge port 18 from opening and scattering the shavings to the outside.

Only when the switch operating knob 5 is operated from the on position to the off position, the operation lock of the shutter mechanism 19 is released, and the lint discharge port 18 can be freely opened and closed.

In addition, when cleaning the debris after that, the switch operating knob 5 cannot be operated from the off position to the on position unless the debris discharge port 18 is completely opened. Therefore, at the time of discharging shavings, first set the switch operation knob 5 to the off position to open the shaving discharge port 18, determine the shaving discharge position in advance and make sufficient preparations, and then operate the switch operation knob 5 to the on position. Then, the work of discharging the hair waste will be performed. This means that by opening the shaving discharge port 18 later while the razor blade unit 3 is being driven by the motor 2, it is possible to prevent undesired scattering of shavings outside.
