- Although not shown in the publication, the outer blade is held on the cleaning ring side for discharging beard debris, and when the cleaning ring is moved when cleaning beard debris, the outer blade also moves to the inner blade. It was supposed to move against. [Problems to be Solved by the Invention] However, in such a device in which the outer cutter is moved relative to the inner cutter, the inner cutter may wobble, especially when the outer cutter is moved in a direction away from the inner cutter. , tj of the present invention
As shown in Figure S15, when cleaning the beard debris with the blade facing downward, there was a problem in that when the inner cutter was rotated, the inner cutter could hit unevenly and become deformed. In addition, in the case where the beard 7i11+ outlet is opened and closed by rotating the cleaning ring,
There is a problem in that one of the beard waste discharge holes may be open when the blade protection cap is not conveniently put on, and beard waste may be accidentally scattered when the electric razor is carried. The present invention was made in view of such problems,
The purpose of this is to avoid changing the relative position of the inner and outer blades when cleaning beard debris, to avoid wobbling of the inner blades, to avoid damage to the inner and outer blades, and to have a blade protection cap. To provide an electric shaver in which a beard waste discharge port is not opened when not in use and the beard waste is not accidentally scattered when not in use. Means for Solving the Problem 1 The electric shaver of the present invention includes an outer cutter 1, an inner cutter 2, and a blade protection cap 13 that covers the outer cutter 1, and has a beard waste discharge port in a blade mount 3 on which the outer cutter 1 is attached. An electric shaver in which the beard waste outlet 4 is opened using a cleaning ring 5 attached to the outer surface of the blade mount 3. There, the cleaning ring 5 is attached to the outer cutter 1 and the inner cutter 2.
The cleaning ring 5 is configured to be movable in the axial direction of the cleaning ring 5.
is characterized in that it is configured to abut against the blade protection camp 13 in the closed position in which the beard waste discharge port 4 is closed. [Function] In this way, the beard waste discharge port 4 is opened in the blade mount 3 on which the outer cutter 1 is attached, and the cleaning ring 5 attached to the outer surface of the blade mount 3 is connected to the shaft of the outer cutter 1 and the inner cutter 2. When cleaning beard debris, the cleaning ring 5, which is independent of the outer cutter 1, is moved to open the beard debris outlet 4, and the inner and outer blades 2.1 are moved relative to each other. The beard debris can be discharged without changing the position, and there is no possibility that the inner and outer blades 2, 1 will be deformed due to the inner and outer blades 2 wobbling by changing the relative positions of the inner and outer blades 2.1 during cleaning. Moreover, by configuring the cleaning ring 5 to abut against the blade protection cap 13 in the closed position in which the cleaning ring 5 closes the whisker debris discharge port 4, the whisker debris discharge port 4 can be closed by the cleaning ring 5. The blade protection cap 13 can be attached when the blade protection cap 13 is attached, that is, the beard waste discharge port 4 is always closed when not in use when the blade protection character 7'13 is attached. This is to prevent the accidental scattering of beard debris. E Example 1 Examples of the present invention will be described in detail below with reference to the accompanying drawings. 6 is the main body of the razor, which includes a housing 14, a lower cover 15, a dial 16 for attaching and detaching the lower cover 15, and a switch 1.
7. Consists of internal components (not shown) such as batteries. A motor 18 and the like are incorporated in the upper part of the razor body 6, as shown in FIG. That is, an M-type sealing material 20 for airtightness (waterproofing) is inserted into the motor shaft g19, and this motor shaft portion 19 is attached to the motor mounting base 11.
Insert the motor] 8 into the through hole 21 of the motor mounting base 11.
Fix it to the bottom surface with a hook (not shown) or the like, fit the green part of the 7-run no. 22 of this motor mounting base 11 into the upper end opening of the unong 14 via the rubber ring 23 for sealing (waterproofing), and install the motor. The base 11 is attached to the housing 1 by screws 24.
It is fixed at 4. 3 is a blade mount for screwing the outer blade 1, 5 is a cleaning ring that surrounds the outer circumferential surface of the blade mount 3, and the blade mount 3 is installed after the cleaning ring 5 is inserted into the outer periphery. , is fixed to the motor mounting base 11 with screws 25. Further, a joint 26 is press-fitted into the motor shaft portion 19, and the inner cutter 2 is attached to the joint 26, and the outer cutter 1 is screwed onto the blade mount 3. A blade protection cap 13 can be placed over the outer cutter 1 when not in use, and a claw 27 on the inner circumference of the blade protection cap 13 is fitted into a ring groove 28 on the outer circumference of the outer cutter 1. As shown in FIGS. 6 and 7, a threaded portion 29 for attaching the outer cutter 1 is provided on the inner periphery of the blade mount 3, and a flange 9 is protruded from the outer periphery of the upper end. A plurality of oblong beard waste discharge ports 4 are opened on the outer periphery of the beard waste outlet 4, and between the beard waste discharge ports 4, the beard waste discharge ports 4 are inclined with respect to the circumferential direction of the outer peripheral surface (
Preferably, an inclined groove 7 (preferably with an inclination angle a = 15° to 30°) is carved, the lower end of the inclined groove 7 communicates with a horizontal lower straight part 31 opened on the lower end surface, and the upper end of the inclined groove 7 is connected to the flange. It communicates with an upper straight part 30 provided horizontally below the part 9 along the collar part 9. Furthermore, an upper click boss 32 and a lower click boss 3 are provided at the upper and lower parts of the outer peripheral surface of the blade mount 3, respectively.
3 is provided with the same pitch as the inclined groove 7. On the other hand, an anti-slip uneven part 34 is provided on the outer periphery of the cleaning ring 5, a ring protrusion 35 is provided on the upper end thereof, and a protrusion 8 is provided on the lower end of the inner peripheral surface of the cleaning ring 5 to prevent rattling. The ribs 10 are provided to protrude inward. Furthermore, an elastic piece 3 is provided at the lower end of the inner circumferential surface of the cleaning ring 5 to provide elasticity by providing a slit groove 36 around the periphery.
7, and a substantially triangular click protrusion 38 is provided on the elastic piece 37. Then, during assembly, the protrusion 8 is housed in the lower straight part 31 so that the protrusion 8 is slidably fitted into the inclined groove 7, and the blade mount 3 is fixed to the motor mount 11 as described above. In the normal state, as shown in FIG. 4, the cleaning ring 5 stops and retracts when its lower surface abuts the end surface of the housing 14, and the protrusion 8 is located within the lower straight portion 31 and clicks. The protrusion 38 elastically rides over the lower click boss 33 to prevent the cleaning ring 5 from moving inadvertently. In this state, there is a gap (c) between the outer periphery of the blade mount 3 and the inner periphery of the cleaning puffer fish 5, but this gap (c) is closed by the end face of the housing 14 and the alligator part. ,
This prevents beard debris from spilling outside the cleaning ring 5. When cleaning whisker 7F'l,
When you turn the cleaning ring 5 with a little force, the click protrusion 3
8 elastically climbs over the lower click boss 33 and the cleaning ring 5 becomes free. When the cleaning ring 5 is further turned, the protrusion 8 is guided in the inclined groove 7 and moves, thereby removing the cleaning ring 5. stands out. At this time, the inner surface of the rib 10 comes into sliding contact with the inner surface of the blade mount 3, and the flange 9 comes into sliding contact with the inner peripheral surface of the cleaning rib 5, so that the cleaning ring 5 moves without rattling. Further, as the cleaning ring 5 rises, the blade protection camp 13 is also pushed up, and the blade protection a cap 13 is naturally removed from the outer blade 1. When the cleaning ring 5 rises and the protrusion 8 reaches the inside of the upper straight part 30, the protrusion 8 hits the lower surface of the flange part 9 and stops. When the cleaning ring 5 is turned with a little force, the protrusion 8 moves into the upper straight part 30. While moving, the click protrusion 38 clicks over the click boss 32 as shown in FIG. 5, and locks the cleaning ring 5 so that it does not return. In this state, as shown in Figure fJIJ15, submerge up to 3 parts of the blade mount in water, turn on the switch 17 and rotate the inner blade 2, a water flow will be generated, and beard debris will be discharged from the beard debris outlet 4 along with the water flow. They are thoroughly washed with water. After cleaning, the cleaning ring 5 may be operated in reverse to return it to its original state. In addition, the vJ2 diagram shows the protection of the outer blade 1 during cleaning of whisker debris.
It represents 91 years old. In other words, if the electric razor is dropped when cleaning beard debris, the outer blade 1 is most likely to be damaged, so when the cleaning ring 5 is protruded, its tip surface is δ higher than the apex A of the outer blade 1. It is designed to protrude and protect the outer cutter 1. In addition, FIG. 9 shows another structure for protecting the outer blade 1 when it is dropped or stored, in which the blade mounting base 3 of the electric razor is bent in an oval shape relative to the razor body, and the cleaning ring 5 is When protruding, the external force 1 should be retracted by δ' from the imaginary line connecting the lower end of the razor body 6 and the tip of the cleaning ring 5 on the bent side (inner fill). It is 7. As shown in FIG. 9, even when the razor body 6 and the blade are drained after washing with water, this can be done without damaging the outer cutter 1, which is directed downward. Furthermore, if the ring protrusion 35 of the cleaning ring 5 is integrally molded with an elastic material such as rubber, it will prevent slipping during rotation of the cleaning ring 5 and improve the feel. Can be done. In the illustrated example, the beard waste discharge ports 4 are opened at three locations, but it is also possible to open them over the entire outer periphery of the shaft. The inclination angle of the inclined groove 7 is as described above.
6 = 15° to 30°, but this is the inclination angle α
If the angle a is small, the angle of rotation to open the beard waste outlet 4 will become large, making it difficult to use.On the other hand, if the inclination angle a is large, the opening (intersection of) between the upper and lower straight parts 30 and 31 and the inclined groove 7 This is because there is a problem that the angle change becomes 8 drastic, and the cleaning ring 5 feels like a two-step click, and the operating force becomes stiff. What is shown in FIGS. 10 to 14 is another part of the present invention, in which the cleaning ring 5 is operated in a straight manner. As shown in Figure t512 and Figure 13, the blade mount 3 has a beard waste discharge port 4, and at the opening of the beard discharge port 4, a vertically stepped click ridge 39 is formed. Idle strips 40 that are higher than the click ridges i39 are made to protrude in the vertical direction on both sides of the ridges ff1s39. On the other hand, a click protrusion 38 is provided on the elastic piece 37 on the inner periphery of the cleaning ring 5 . Thus, the cleaning ring 5 is fitted onto the outer periphery of the blade mount 3. The click protrusion 38 is housed between the γ-id strips 40 and the click protrusion 38 is restricted between the 141 strips 40 to prevent the cleaning ring 5 from rotating. The cleaning ring 5 slides while clicking by elastically passing over the peak 39. Furthermore, a spring body 12 is interposed between the end surface of the housing 14 and the cleaning ring 5. When the cleaning ring 5 is pushed a little, the cleaning ring 5 is automatically projected by the elastic force of the spring body 12 and the beard waste outlet 4 is opened, and conversely, when the beard waste outlet 4 is closed. It is sufficient to push the cleaning ring 5 against the elastic force of the spring body 12 and withdraw it. In this embodiment, the cleaning ring 5 is moved by the spring body 12.
Although the cleaning ring 5 is biased in the protruding direction, the spring body 12 may be attached so as to bias the cleaning ring 5 in the retracting direction to facilitate the return of the cleaning ring 5. What is shown in FIGS. 16 to 18 is still another side of the present invention, and shows the case of a reciprocating electric shaver, in which the housing 14
A beard waste discharge port 4 is opened on the side of the blade mount 3 that is integrated with the blade mount 3, and a lid-shaped cleaning ring 5 is attached to this beard waste discharge port 4 so as to be able to slide up and down. At the same time as sliding the blade to open the beard waste outlet 4,
The J cap 13 is also pushed and automatically detached from the outer cutter 1. In the above embodiment, the cleaning ring 5 does not have an outlet for discharging whisker debris, but the present invention is not limited to this, and the cleaning ring 5 also has an outlet for discharging whisker debris. A discharge port may be formed, and this discharge port may be aligned with the beard waste discharge port 4 to discharge the beard waste, or the discharge port of the cleaning ring 5 may be shifted from the beard waste discharge port 4 to be closed. .

【Effect of the invention】

In summary, the present invention has a blade mount on which the outer cutter is attached with a beard waste discharge port, and a cleaning ring attached to the outer surface of the blade mount so as to be movable in the axial direction of the outer cutter and the inner cutter. Because of this, when cleaning beard debris, the cleaning ring, which is independent of the outer blade, is moved to open the beard debris discharge port, and the beard debris can be discharged without changing the relative position of the inner and outer blades. When cleaning, the blades are not deformed due to changing the relative positions of the inner and outer blades and causing the inner blades to wobble, and the cleaning ring is in a closed position where the cleaning ring closes off the shavings discharge. Since the blade is dry so that it comes into contact with the protective cap, the blade protective cap can be installed with the beard waste outlet closed with the cleaning ring, which means that when the blade protective cap is installed and not in use. The beard debris discharge port is always open, which has the advantage that beard debris will not be accidentally thrown away when not in use, such as when carrying an electric razor.
