Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric shaver.

Conventionally, a beard debris reservoir formed at one end of the main body case is selectively communicated with the outside, at least one end of the main body case on the side of the beard debris reservoir is immersed in water, and in this state, the inner blade is rotated to enter the interior. There is a model that releases accumulated hair debris using a stream of water, but the source of the water stream is the inner blade, and the area where it is generated is near the contact between the inner surface of the outer blade and the inner blade, so the hair debris collection area is The amount of water that reaches the bottom of the tank is small, and the sticky debris is difficult to remove.

The object of the present invention is to provide an electric shaver that can eliminate the above-mentioned drawbacks.

This invention provides an outer blade attachment portion at one end of a main body case that houses a motor in a watertight manner, and forms a whisker waste storage portion watertightly isolated from the inside of the main body case inside the outer blade attachment portion. The rotary shaft of the motor is made to protrude into this whisker waste storage portion while maintaining watertightness, and an inner cutter is connected to the protruding end thereof, and an outer cutter case having an outer cutter that is pressed into contact with the inner cutter is attached to the outer cutter case. A communication part is formed in the outer cutter case and the outer cutter mounting part to selectively communicate the beard waste collection part to the outside, and a communication part is formed in the outer cutter case and the outer cutter attachment part to selectively connect the beard waste collection part to the outside. The present invention is characterized in that an agitating body that performs a high water flow generation function without performing an air flow generation function is provided in communication with the rotating shaft. In other words, when shearing hair, the inner blade is rotated with the communication section closed, but at this time, no airflow is effectively generated, so there is no amount of beard debris flying around in the beard debris collection section, and the communication section is not opened. The water is purified by immersing the whisker debris reservoir in water, and not only the inner blade but also the stirring body rotates to effectively generate a water flow, which draws water from the outer blade and creates a vortex in the whisker debris reservoir. It is configured so that the discharge action from the communication portion can be carried out actively, and it can be washed cleanly and quickly with water.

An embodiment of the present invention will be described based on the drawings.
Reference numeral 1 is a cylindrical main body case that can be divided into two parts, and the water density at the outer periphery is high due to the packing 2 that is sandwiched and provided at the dividing edge. The lid body 3 is inserted into the rear end, but since the fitting part is provided with packing (not shown) and the lid body 3 itself is formed of an elastic member such as hard rubber and is press-fitted, the fitting is difficult. The water density at the junction is extremely high. A battery 4 and a motor 5 are housed within the main body case 1. Further, a switch 6 is provided on the side surface of the main body case 1 to electrically connect and disconnect the motor 5 and the battery 4. The contact part of this switch 6 is located inside the main body case 1, and the switch knob 7 is located outside and partially protrudes into the main body case 1 to switch the contact. For this purpose, an operating hole is formed through which a part of the switch knob 7 protrudes. (not shown) is configured as a waterproof switch 6 by forming the switch knob 7 from an elastic material such as hard rubber and bringing it into close contact with the operating hole. At the tip of the main body case 1, an outer blade mounting base 9, which is an outer blade mounting part that forms a beard waste storage part 8 inside, is screwed in a watertight manner with a sheet-like packing 10 in between. The rotating shaft 11 of the motor 5 is held by a bearing (not shown) provided in a bearing holder 12 and a seal member (not shown) and protrudes into the whisker waste storage part 8, and the protruding part has a plurality of inner parts. Blade 1
An inner cutter stand 14 that resiliently holds the blade 3 is detachably inserted while being prevented from rotating, and an agitator 15 located at the bottom of the whisker waste storage portion 8 is connected while being prevented from rotating. The agitating body 15 is surface-treated with chrome plating or fluorine resin coating to reduce the adhesion of whisker debris, etc., and has a plurality of ribs 16 arranged in a radial pattern with a gently undulating corrugated cross section. ing. Further, an outer cutter case 18 that holds an outer cutter 17 that resiliently contacts the inner cutter 13 is removably fitted into the outer cutter mount 9. By forming a plurality of openings 19 and 20 in the peripheral walls of the outer cutter mount 9 and the outer cutter case 18, a communication section 21 is formed that selectively communicates the hair debris storage section 8 with the outside. That is, at the lower part of the fitting part between the outer cutter case 18 and the outer cutter mount 9, a locking part (not shown) is formed that engages each other so that the mounting angle in the circumferential direction can be freely changed. , 20 may be closed with their positions shifted from each other as shown in FIG. 3, or they may be aligned and communicated as shown in FIG. 4. These openings 19,
The edge of the opening 20 is inclined in a direction that substantially coincides with the tangential direction of the outer circumference of the stirring body 15.

In such a configuration, shaving is performed by setting the outer cutter case 18, closing the communication portion 21, and driving the motor 5 as shown in FIG. At this time, the stirring body 15 rotates at the same time,
As shown in FIG. 2, the ribs 16 have a corrugated cross-section and a low protruding height, so the airflow generated by the agitator 15 is extremely low. Therefore, there is no possibility that beard debris will fly around in the beard debris reservoir 8. Outer blade case 1
8 at different angles as shown in FIG. 4, the communicating portion 21 is opened, at least the tip of the main body case 1 is immersed in water, and the motor 5 is driven. At this time, since water has a higher viscosity than air, a swirling water flow can be obtained even if the ribs 16 are low and have gentle undulations. This water flow is generated at the bottom of the whisker debris reservoir 8.
That is, water is drawn in from the outer cutter 17, swirls within the whisker debris reservoir 8, and is discharged from the communication portion 21. At this time, since the opening edges of the openings 19 and 20 are inclined in line with the tangential direction of the stirring body 15, the force of the water is not impaired. Therefore, the beard waste storage section 8
Even whisker debris and oil scale stuck to the bottom of the blade, and whisker debris and oil scale stuck to the inner surface of the outer cutter 17 and the cutting edge of the inner cutter 13 can be hygienically and promptly discharged.

Although the description has been made with a low rib 16 having gentle undulations as a means of extremely reducing the air generation effect and increasing the water flow generation effect, the rib 16 is connected to one pole of the motor 5 as a switch 6 as shown in FIG. Contacts a and e connected to the other pole and contacts b and d connected to the other pole
In this case, a movable contact c is connected to the battery 4 for each pole, and a movable contact c is connected to the contact a or b, and a movable contact f is connected to the contact d or e. On the other hand, the stirring body is formed with blades having a shape that makes it difficult to generate water flow or air flow when rotated in one direction, but easily generates water flow or air flow when rotated in the other direction. Therefore, by setting the direction of current to battery 4 - movable contact c - contact a - motor 5 - contact d - movable contact f - battery 4, motor 5 can be rotated in one direction, and conversely, the direction of current can be changed to battery 4 - movable contact c - contact a - motor 5 - contact d - movable contact f - battery 4. By using 4-movable contact c-contact b-motor 5-contact e-movable contact f-battery 4, the motor 5 can be rotated in the other direction. Therefore, neither air flow nor water flow is effectively generated during shaving, and water flow can be actively generated during washing by rotating the stirring body in the opposite direction to that used during shaving. Alternatively, the stirring body 15 is connected to the rotating shaft 1 through a clutch (not shown).
1, the agitator 15 may be stopped to generate an air flow when shaving, and the agitator 15 may be rotated only during water washing to generate a water flow. If a one-way clutch is used as the clutch, it is possible to stop the agitator 15 when shaving with the motor 5 rotated in one direction, and rotate the agitator 15 when washing with water by rotating the motor 5 in the other direction. It is convenient because there is no need to perform intermittent operations.

Since the present invention is constructed as described above, during washing, a swirling water flow is actively generated by the agitator provided at the bottom of the beard debris storage section, thereby quickly discharging the beard debris from the communication portion without leaving any residue. This has the effect that when shaving, the communication portion is closed and the hair can be sheared without creating an air flow that would blow up beard debris into the beard debris reservoir.
