Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized by rotating the inner cutter in the inner cutter storage chamber while pouring water into the inner cutter storage chamber through a fixed outer cutter made of a porous screen. The object of the present invention is a water-washable electric shaver having a structure in which hair waste in an inner blade storage chamber is discharged together with water from an outlet drilled in an outer peripheral wall.

[Prior art and its problems]

In this type of electric shaver, the drain port can be opened and closed with a lid, so that the drain port is closed when shaving and opened when washing hair with water. However, in the conventional structure, the motor start/stop switch and the drain outlet cover are placed at separate locations, and for example, when washing hair with water, the motor switch operation and the cover opening operation are required. This had to be done separately, which was extremely inconvenient.

The present invention has focused on this fact, and has made it possible to simultaneously operate the motor switch and open/close the lid with a single fingertip.

〔Example〕

Hereinafter, a specific example thereof will be explained based on the drawings.

In FIGS. 1 to 3, 1 is a cylindrical razor main body, and 2 is a head case screwed to the upper end of the main body.

The razor main body 1 has a built-in motor 3 in its upper part, and one AA battery 4 in its lower part. head case 2
An outer cutter 5 made of a porous screen is screwed and fixed to the upper end of the head case via a holder 6, and a holder 9 supports a plurality of inner cutters 8 that slide on the inner surface of the outer cutter 5 in an inner cutter storage chamber 7 in the head case. This inner blade holder 9 is engaged and connected to the output shaft 10 of the motor 2, and a rotary blade 11 is installed on the lower side of the inner blade holder 9.
The circular outer peripheral side wall 12 of the inner cutter storage chamber 7
A drain port 14 which is opened and closed by a lid body 13 is bored in the drain port 14.

Then, when the inner blade holder 9 is rotated while pouring water into the inner blade storage chamber 7 through the outer blade 5, the rotating blade 11 is also rotated through the water circulating in the storage chamber, and the water containing hair waste inside is rotated. The basic structure is that water is discharged to the outside from a drain port 14.

2 and 5, a ring 15 is slidably and rotatably interposed between the razor body 1 and the head case 2, and the lid 13 and the lid A slide knob 16 for opening/closing operation is installed upright, and the knob 16
The drain port 14 can be opened and closed by the cover body 13 by rotating the entire ring through the pin 17 protruding from the lower surface of the ring 15 and the pin 1 protruding from the lower surface of the head case 2.
A tension spring 19 is tensioned between the ring 15 and the ring 15 to rotate in a certain direction, and the lid 13 completely closes the drain port 14 at the limit of the biasing rotation.

In FIGS. 5 and 7, a circumferentially extending cantilevered retaining arm 20 is connected to the inner side of the ring 15 so as to be elastically deformable in the inner and outer directions, and the lid body 13 opens the drain port 14. When the ring 15 is slid and rotated to this position, the retaining protrusion 21 provided at the tip of the engagement arm 20 engages with the chevron-shaped rib 22 protruding from the lower surface of the head case 2. However, the engagement force between the engagement arm 20 and the chevron rib 22 is set to be stronger than the restoring force of the stretched spring 19,
A retaining mechanism 2 that holds the lid body 13 in the drain opening position
3.

4 and 5, a stopper 24 made of a temporary spring is fixed to the inner surface of the lid 13 in a cantilevered manner, and when the lid 13 closes the drain port 14, the extending end of the stopper 24 is fixed to the inner surface of the lid 13. The rotating blade 11 in the inner blade storage chamber 7 from the opening 14
protrudes into the rotation locus of and prevents rotation of the rotary blade 11,
When the drain port 14 is opened, the rotating blade 11 comes out of the drain port.
It is designed to allow rotation.

1 and 2, a waterproof slide switch 25 for starting and stopping the built-in motor 3 is installed on the outer circumference of the upper end of the razor body 1, and its slide knob 26 is arranged below the slide knob 16. Place it in This slide switch 25 is constructed by inserting and fixing a switch case 28 into a window provided in the razor body 1 through an elastic rubber gasket 27, and attaching the slide knob 28 to the switch case 28.
is slidably supported in the circumferential direction, and when the knob 26 is slid to the switch-on position, the gasket 27 is pushed inward, thereby deforming the movable terminal 29 located deep inside the teller inward and fixing it. The structure is such that the ζ battery 4 and the motor 3 are electrically connected by contacting the terminal 30. Incidentally, the movable terminal 29 is connected to the cathode of the battery 4 via a metal battery support spring 31, the fixed terminal 30 is connected to the cathode terminal on the motor side, and the anode of the battery 4 is connected to the anode at the bottom of the motor 3. It is connected to the terminal 32 by contact.

The drain opening/closing knob 16 and the switch operating knob 26, which are arranged vertically in parallel, are provided with engaging portions 33 and 34, respectively, so that the knob 16 is in the drain opening position as shown in FIG. 7(B). When the knob 26 is in the switched-on position, the re-engaging portions 33, 34 are adapted to engage in abutting engagement.

In such a case, both knobs 16 and 26 can be slid simultaneously or individually with one thumb of the hand holding the razor body 1. That is, during normal shaving, only the switch operation knob 26 is operated. Both knobs 16 when washing hair waste with water.
, 26 to the right at the same time, the drain port 14
When the inner cutter 8 opens, the inner cutter 8 can be rotated. In this state, both knobs 16 and 26 are in the position of the engagement mechanism 23.
The razor body 1 is held in place by the user, and the user can wash his/her hand with water while moving his or her hand to the lower part of the razor body 1 to avoid splashing water from the drain port 14. After washing the hair in the inner blade storage chamber 7 with water, simply return the lower knob 26 to the switch-off position, and the upper knob 16 will be returned slightly by the contact interference of the engaging portions 33 and 34, and the ring will close. 15 rotates and the engagement arm 20
The engagement protrusion 21 is disengaged from the chevron lip 22, and the ring 15 is rotated back by the tension spring 19.
3 will automatically close. Therefore, the drain port 14 will not remain closed during the next shave. Also, knob 16. Since the knob 1 must be slid to the open position against the tension spring 19, the knob 1 must be slid to the open position against the tension spring 19.
There is no possibility of accidentally opening the drain port 14 by operating the button 6. This was done as described above.

In the illustrated example, the lid body 13 is urged to close by the tension spring 19 and held in the open position by the engagement mechanism 23, but the engagement mechanism 23 is omitted in order to simplify the structure. However, the lid 13 may be always urged to close. However, in this case, when washing hair waste with water, please use knob 16.
It is necessary to hold it in the open position side with your fingertips, and the cover body 1
You won't forget to close 3, but your hands will get wet. However, the tension spring 19 itself can also be omitted.

Further, the drain port 14 may be bored in the outer peripheral portion of the bottom wall of the inner blade storage chamber 7.

Furthermore, the present invention envisages a configuration in which both the knobs 16, 26 are disposed close to the upper part of the razor body 1 in a left-right parallel manner, and are slidable in the vertical direction.

[Effects of the Invention] As explained above, according to the present invention, the slide knob 26 for operating the switch and the slide knob 1 for opening and closing the drain port
6 are placed close together so that they can be operated with a single fingertip, so that by simply grasping the shaver body 1 and moving the fingertips of one hand in the same direction, the switch 25 can be turned on and off and the drain port 14 can be opened and closed in conjunction with each other. It is extremely easy to use, especially when washing hair waste with water.

In addition, in the second aspect of the invention, since the sliding operation force of the slide knob 16 for opening and closing the drain port is large, when shaving, one of the knobs 16 is slid at the same time and the drain port 14 is opened by mistake. It has the advantage that it does not get lost.

Detailed Description of the Invention [Field of Industrial Application] This invention provides an inner cutter that rotates the inner cutter in the inner cutter storage chamber while pouring water into the inner cutter storage chamber through a fixed outer cutter made of a porous screen. The object of the present invention is a water-washable large electric shaver having a structure in which hair waste in a storage chamber is discharged together with water from an outlet drilled in an outer peripheral wall. [Prior art and its problems] In this type of water-washable large electric razor, the drain port can be opened and closed with the lid body, the drain port is closed when shaving, and the drain port is opened when washing hair waste, and the water is poured from the outer blade etc. Water passes through the inner blade storage chamber and is discharged from the drainage port along with hair debris. However, with conventional structures, even when washing with water, the inner blade is rotated and a swirling water flow is generated within the inner cutter storage chamber, even hair particles stuck to the inner wall of the inner cutter storage chamber are washed away. The cleaning efficiency was poor. This invention focuses on this fact, and by arranging a rotary blade that is rotated by the swirling water flow accompanying the rotation of the inner cutter holder at a position below the inner cutter holder in the inner cutter storage chamber,
The rotation of this rotary blade forcibly removes the hair debris attached to the inner wall of the inner cutter housing chamber, and the rotation of the rotary blade is prevented by a stopper during normal shaving. . [Example] Hereinafter, a specific example thereof will be explained based on the drawings. In FIGS. 1 to 3, 1 is a cylindrical razor main body, and 2 is a head case screwed to the upper end of the main body. The razor main body 1 has a built-in motor 3 in its upper part, and a single AA battery 4 in its lower part. head case 2
An outer cutter 5 made of a porous screen is screwed and fixed to the upper end of the head case via a holder 6, and a holder 9 supports a plurality of inner cutters 8 that slide on the inner surface of the outer cutter 5 in an inner cutter storage chamber 7 in the head case. The inner blade holder 9 is fixedly connected to the output shaft 10 of the motor 2, and the rotating blade 11 is installed on the lower side of the inner blade holder 9.
The circular outer peripheral side wall 12 of the inner cutter storage chamber 7
A drain port 14 which is opened and closed by a lid body 13 is bored in the drain port 14. Then, when the inner cutter holder 9 is rotated while pouring water into the inner cutter storage chamber 7 through the outer cutter 5, the rotating blade 11 also rotates through the water circulating inside the storage chamber and adheres to the inner wall of the inner cutter storage chamber 7. The basic structure is such that the hair waste is forcibly removed by the rotating blade 11, and the water containing the hair waste inside is discharged to the outside from the drain port 14. 2 and 5, a ring 15 is slidably and rotatably interposed between the razor body 1 and the head case 2, and the lid 13 and the lid A slide knob 16 for opening/closing operation is installed upright, and the knob 16
The drain port 14 can be opened and closed by the cover body 13 by rotating the entire ring through the pin 17 protruding from the lower surface of the ring 15 and the pin 1 protruding from the lower surface of the head case 2.
A tension spring 19 is tensioned between the ring 15 and the ring 15 to rotate in a certain direction, and the lid 13 completely closes the drain port 14 at the limit of the biasing rotation. In FIGS. 5 and 7, a circumferentially extending cantilevered retaining arm 20 is connected to the inner side of the ring 15 so as to be elastically deformable in the inner and outer directions, and the lid body 13 opens the drain port 14. When the ring 15 is slid and rotated to this position, the retaining protrusion 21 provided at the tip of the engagement arm 20 engages with the chevron-shaped lip 22 protruding from the lower surface of the head case 2. However, the engagement force between the engagement arm 20 and the chevron rib 22 is set to be stronger than the restoring force of the stretched spring 19,
Engagement mechanism 2 that holds the lid 13 in the drain opening position
3. 4 and 5, a stopper 24 made of a temporary spring is fixed to the inner surface of the lid 13 in a cantilevered manner, and when the lid 13 closes the drain port 14, the extending end of the stopper 24 is fixed to the inner surface of the lid 13. It protrudes from the opening 14 into the rotation locus of the rotary blade 11 in the inner blade storage chamber 7 to prevent rotation of the rotary blade 11, and when the drain port 14 is opened, it comes out of the drain port and prevents the rotation of the rotary blade 11. It is designed to allow movement. That is, in a state in which the drain port 14 is closed, that is, in a so-called shaving state, the rotation of the rotary blades 11 is prevented by the stopper 24, so that the rotation of the rotary blades 11 due to the swirling airflow accompanying the rotation of the inner blade holder 9 during shaving is prevented. In addition to preventing unnecessary rotation, the rotating blade 11 conversely divides and prevents the generation of swirling airflow in the inner cutter storage chamber 7, so that the outer cutter 5
It is possible to reduce the scattering of hair debris from the rotary blade 1 when the drain port 14 is opened during washing.
1 rotation is allowed. 1 and 2, a waterproof slide switch 25 for starting and stopping the built-in motor 3 is installed on the outer circumference of the upper end of the razor body 1, and its slide knob 26 is arranged below the slide knob 16. Place it in This slide switch 25 is constructed by inserting and fixing a switch case 28 through an elastic rubber gasket 27 into a window provided in the razor body l, and attaching the slide knob 26 to the switch case 28.
is slidably supported in the circumferential direction, and when the knob 26 is slid to the switch-on position, the gasket 27 is pushed inward, which deforms the movable terminal 29 in the inner part of the teller inward and turns it into a fixed terminal. By contacting the battery 4 and the motor 3, the battery 4 and the motor 3 are electrically connected. Incidentally, the movable terminal 29 is connected to the cathode of the battery 4 via a metal battery support spring 31, the fixed terminal 30 is connected to the cathode terminal on the motor side, and the anode of the battery 4 is connected to the anode at the bottom of the motor 3. It is connected to the terminal 32 by contact. The drain opening/closing knob 16 and the switch operating knob 26, which are arranged vertically in parallel, are provided with engaging portions 33 and 34, respectively, so that the knob 16 is in the drain opening position as shown in FIG. 7(b). When the knob 26 is in the switched-on position, the reassembly portions 33, 34 are adapted to abut and engage. In such a case, both knobs 16 and 26 can be slid simultaneously or individually with one thumb of the hand holding the razor body 1. In other words, when shaving normally, only the switch operation knob 26 is operated, and when rinsing with water, both knobs 16 are operated.
．． 26 to the right at the same time, the drain port 14
When the inner cutter 8 opens, the inner cutter 8 can be rotated. In this state, both knobs 16 and 26 are in that position with the engagement mechanism 23.
The razor body 1 is held in place by the user, and the user can wash his/her hand with water while moving his or her hand to the lower part of the razor body 1 to avoid splashing water from the drain port 14. After washing the hair in the inner blade storage chamber 7 with water, simply return the lower knob 26 to the switch-off position, and the upper knob 16 will be returned slightly by the contact interference of the engaging portions 33 and 34, and the ring will close. 15 rotates and the engagement arm 20
The engagement protrusion 21 is disengaged from the chevron-shaped rib 22, and the ring 15 is rotated back by the tension spring 19.
3 will automatically close. Therefore, the drain port 14 will not remain closed during the next shave. Further, since the knob 16 must be slid to the open position against the tension spring 19, the knob 16 must be slid to the open position against the tension spring 19.
There is no need to accidentally open the drain port 14 by operating the . This was done as described above. In the illustrated example, the lid body 13 is urged to close by the tension spring 19 and held in the open position by the retaining mechanism 23, but the engaging mechanism 23 is omitted in order to simplify the structure. However, the lid 13 may be always urged to close. However, in this case, when washing hair waste with water, please use knob 16.
It is necessary to hold it in the open position side with your fingertips, and the cover body 1
You won't forget to close 3, but your hands will get wet. However, the tension spring 19 itself can also be omitted. Further, the drain port 14 may be bored in the outer peripheral portion of the bottom wall of the inner blade storage chamber 7. Furthermore, the present invention envisages a configuration in which both the knobs 16, 26 are disposed close to the upper part of the razor body 1 in a left-right parallel manner, and are slidable in the vertical direction. [Effects of the Invention] As explained above, according to the present invention, the outer cutter 5 made of a porous screen is fixed to the upper end of the head case 2 on the razor body 1 having a built-in motor 3 via the holder 6, A holder 9 supporting an inner cutter 8 that is in sliding contact with the inner surface of the outer cutter 5 is housed in an inner cutter storage chamber 7 in the head case, and is opened and closed by a lid 13 on the outer peripheral wall portion of the lower end of the inner cutter storage chamber 7. Drain port・14
is drilled, and by rotating the inner blade holder 9 while pouring water into the inner blade storage chamber 7 through the outer blade 5, the water containing hair waste in the inner blade storage chamber is discharged to the outside from the drain port 14. In the water-washable electric shaver, rotary blades 11 are freely rotatably supported at a position below the inner cutter holder 9 of the inner cutter storage chamber 7, and the rotary blades 11 are rotated by the swirling water flow accompanying the rotation of the inner cutter holder 9. It is equipped to rotate, and in conjunction with the opening/closing operation of the lid body 13, the lid body 13 protrudes into the rotation locus of the rotary blade 11 in the inner blade storage chamber 7 and rotates when the drain port 14 is closed. The rotary blade 11 is prevented from rotating and the drain port 14 is opened.
Since the stopper 24 is provided to allow the rotary blade 11 to rotate outside of the rotation trajectory, when washing with water, the rotary blade 11 rotated by the swirling water flow removes hair particles stuck to the inner wall of the inner cutter storage chamber 7. The cleaning efficiency is improved by forcibly removing hair debris accumulated in the inner blade storage chamber 7 and draining it from the drain port 14, and at the same time, when shaving, the rotation of the rotary blade 11 is stopped by a stopper 24. This has the advantage that the scattering of hair debris from the external force 5 can be reduced. 4.
