  The head portion 2 is provided with a pair of front and rear short hair cutting blades 14, and a long hair cutting blade 15 is disposed between the both short hair cutting blades 14. The outer blade cleaning body 52 includes a base body 71 guided and supported by a pair of front and rear guide shafts 70, a cleaning body 72 attached to the base body 71, and a drive body 73 that reciprocates the base body 71. The drive body 73 is reciprocally guided by a third guide shaft 85, and a connection groove 90 that engages with the vibrator 25 is formed in the lower part thereof.

  A cleaning body 72 of the outer blade cleaning body 52 includes a fin base portion 81 having an inverted U-shaped cross-section that is externally fitted to the mounting protrusion 74 of the base body 71, and a group of protrusions formed at regular intervals along the longitudinal direction of the fin base portion 81. The blade body 82 is configured.

  The front and rear edges of the blade body 82 are formed in a tapered shape from the lower end side toward the upper edge side.

  A connecting groove 90 that engages with the drive shaft 43 of the vibrator 25 is formed in the drive body 73. The left and right width B 1 of the connecting groove 90 is set to be larger than the left and right width B 2 of the drive shaft 43, and the outer blade cleaning body 52 is reciprocally driven by the drive shaft 43.

  In the present invention, a cleaning device is constituted by the cleaning case 50, the inner blade cleaning body 51 and the outer blade cleaning body 52 supported by the cleaning case 50, and the outer blade for attaching the outer blade holder 13 to the cleaning case 50. A holder mounting portion 62 is provided. At the time of cleaning, the cleaning case 50 is mounted on an electric razor, the outer blade holder 13 removed from the head portion 2 is mounted on the outer blade holder mounting portion 62, and the inner blade 18 and the outer blade 19 are connected to the inner blade cleaning body 51 and The outer blade cleaning body 52 is cleaned at the same time. Thus, according to the cleaning device provided with the inner blade cleaning body 51 and the outer blade cleaning body 52, the inner blade 18 and the outer blade 19 are simultaneously cleaned, and the cleaning of both the blades 18 and 19 can be performed easily with less labor. Yes.

  According to the cleaning device that simultaneously drives the inner blade cleaning body 51 and the outer blade cleaning body 52 with the power of the motor 16 provided in the main body 1, the inner blade 18 is forcibly cleaned with the inner blade cleaning body 51. At the same time, the outer blade 19 can also be forcibly cleaned by the outer blade cleaning body 52 to improve the cleaning effect. Therefore, the inner blade 18 and the outer blade 19 can be reliably cleaned with less effort. Further, since both the cleaning bodies 51 and 52 are driven only by the power of the motor 16 provided in the main body 1, it is possible to prevent the entire structure of the cleaning device from being unnecessarily complicated. Furthermore, the cost required for manufacturing the cleaning device, which is often used as an accessory for an electric shaver, can be suppressed to the extent that the overall structure can be simplified.

  When the outer blade cleaning body 52 is disposed in a state where the front and rear thereof are close to the front and rear walls of the outer blade 19 and the upper end thereof is opposed to the curved wall of the outer blade 19 via the flow gap E, the flow gap The inner surface of the outer blade 19 can be reliably cleaned while the cleaning liquid is evenly distributed over the entire outer blade cleaning body 52 and the outer blade 19 facing E. Moreover, the hair and sebum adhering to the front and rear walls of the outer blade 19 are forcibly washed by the outer blade cleaning body 52, and the front and rear walls of the outer blade 19 where the hair and sebum easily collect are kept clean. it can. The dust and sebum washed away from the outer blade 19 are discharged to the outside through the hole of the outer blade 19 facing the flow gap E, and the outer blade 19 can be effectively cleaned in a shorter time.

  According to the cleaning device that supports the outer blade cleaning body 52 so as to be reciprocally movable by the cleaning case 50 and is driven to reciprocate by the power of the motor 16, for example, the outer blade 19 is cleaned while the outer blade cleaning body 52 is driven to rotate. Compared to the case, the entire inner surface of the outer blade 19 can be simultaneously and uniformly cleaned by the outer blade cleaning body 52. The outer blade cleaning body 52 stirs and splashes the washing water while reciprocating, and collides with the inner surface of the outer blade 19 to surely wash off the fluff and sebum adhering to the front wall and the rear wall. Further, the vibration effect of the outer blade cleaning body 52 sifts off the dust attached to the outer blade 19 and improves the cleaning effect.

  According to the cleaning device, during cleaning, the inner blade cleaning body 51 is rotationally driven in conjunction with the first inner blade 18, and the driving body 73 provided in the outer blade cleaning body 52 is reciprocated in conjunction with the vibrator 25. Both the inner blade cleaning body 51 and the outer blade cleaning body 52 can be operated simultaneously and reliably. Therefore, cleaning of the inner blade 18 and cleaning of the outer blade 19 can be performed simultaneously and forcibly, and cleaning can be performed more effectively. In particular, the outer blade cleaning body 52 can be positively reciprocated by the vibrator 25 that drives the second inner blade 37 of the long hair cutting blade 15, so that the outer blade 19 can be moved while stirring or splashing the cleaning water. It will be possible to clean every corner.

  According to the cleaning device for reciprocatingly guiding the outer blade cleaning body 52 with the rod-shaped guide shaft 70, sliding resistance and useless movement when the outer blade cleaning body 52 reciprocates are reduced, and there is no power loss. In this state, the outer blade cleaning body 52 can be reciprocated smoothly and lightly. The positional relationship between the outer blade cleaning body 52 and the outer blade 19 is always constant, and the inner surface of the outer blade 19 can be uniformly and uniformly cleaned.

  The long hair cutting blade 15 is disposed between the pair of front and rear short hair cutting blades 14, and the pair of front and rear guide shafts 70 and the third guide shaft 85 guide the base body 71 and the drive body 73 of the outer blade cleaning body 52. Then, the outer blade cleaning body 52 can be slid and guided in a more stable state. Further, since the driving body 73 is guided by the third guide shaft 85 provided near the vibrator 25 and the reciprocating power of the vibrator 25 is transmitted to the outer blade cleaning body 52 through the connecting groove 90, the uppermost The outer cutter 19 can be more accurately cleaned by reciprocatingly driving the outer cutter cleaning body 52 positioned at the position.

  When the outer blade cleaning body 52 is constituted by the cleaning body 72 provided with a group of blade bodies 82 provided along the longitudinal direction of the outer blade 19, the cleaning water is stirred and splashed off by the individual blade bodies 82 that reciprocate. Since the flow form of water can be complicated, the inner surface of the outer blade 19 can be uniformly and reliably washed. The blade body 82 can also exert an action of forcibly scraping off lint and sebum mass stacked on the inner surface of the outer blade 19, and can perform more effective cleaning in cooperation with the stirring action of the cleaning water.

  According to the outer blade cleaning body 52 in which the front and rear edges of the blade body 82 are formed in a tapered shape from the lower end side toward the upper edge side, the cleaning is performed when the blade body 82 is formed of rubber or a soft plastic material. It is possible to eliminate the excessive elastic deformation of the blade body 82 due to the resistance of water. Moreover, since the stirring water flow can be formed on the inner surface side of the curved wall of the outer blade 19 from which the shavings are discharged by the upper narrow blade body 82, the washing water can be more effectively shaken to improve the washing effect. .

  When the left and right width B1 of the connecting groove 90 provided in the drive body 73 is set to be larger than the left and right width B2 of the drive shaft 43 of the vibrator 25, the operation is equal to the difference in the previous width dimension near the stroke end of the drive shaft 43. Due to the delay, the outer blade cleaning body 52 stops. For this reason, the inverted drive shaft 43 impacts against one groove wall of the connecting groove 90 and moves the outer blade cleaning body 52 along with gradually increasing the speed. As a result, each time the drive shaft 43 is reversed at the stroke end, the outer blade cleaning body 52 is slid and moved in an impact manner, and the action of feeding the cleaning water by the blade body 82 is moderately increased. Cleaning can be performed effectively.

The thickness dimension of the blade body 82 is set to be substantially uniform along the peripheral surface of the inverted V-shaped fin base 81.

  The outer blade 19 at the time of cutting the whiskers is pushed up and urged by the inner blade 18 and is in a position indicated by an imaginary line in FIG. However, the outer blade 19 with the outer blade holder 13 removed from the head portion 2 is released from the push-up force by the inner blade 18 and is pulled back to the position indicated by the solid line by the spring force of the outer blade tension structure (not shown). ing. The previous flow gap E is a gap when the outer blade 19 is pulled back to the non-use state by the spring force of the outer blade tension structure.

  The driving body 73 is formed of a plastic molded product integrally including an upper half driving portion 86 that is guided and supported by a third guide shaft 85 so as to be slidable to the left and right, and a connecting body 87 provided on the lower surface of the driving portion 86. . The left and right ends of the guide shaft 85 are supported by bearing bodies 57 (see FIG. 9). The drive unit 86 is formed of a U-shaped frame body that opens upward, and has drive arms 88 that are T-shaped in side view on both the left and right sides, and a passive body 78 of the base body 71 at the front and rear center of the drive arm 88. Is provided with a driving protrusion 89 that engages with (see FIGS. 5 and 11). A connecting groove 90 that engages with the drive shaft 43 of the vibrator 25 is formed at the left and right center of the lower portion of the connecting body 87. When the outer blade cleaning body 52 is driven to reciprocate by the driving body 73, the blade body 82 is elastically deformed in the direction opposite to the moving direction, and the surrounding cleaning water is forced to flow toward the front and rear walls of the outer blade 19.

  In the conventional electric razor, in a state where the outer blade holder 13 is mounted on the first mounting portion 12, both the left and right sides of the drive shaft 43 are clamped by the elastic engagement claws 44 in a slightly elastically deformed state. Are connected without a gap. Accordingly, the inner blade 37 of the center blade 15 can be reciprocated without delay accompanying the reciprocating motion of the vibrator 25. Incidentally, since the vibrator 25 is driven by the rotating eccentric cam 24, the moving speed of the drive shaft 43 becomes maximum at the center of the reciprocating stroke, and the moving speed gradually decreases toward the end of the stroke. Will be zero. Further, the moving speed when the drive shaft 43 moves in the reverse direction from the stroke end gradually increases. Therefore, the inner blade 37 is driven in the reverse direction at a position where the moving speed of the drive shaft 43 is close to zero and can be smoothly reversed and moved.

  On the other hand, in a state where the outer blade holder 13 is mounted on the outer blade holder mounting portion 62 of the cleaning case 50, the connecting groove 90 provided in the connecting body 87 engages with the drive shaft 43 as shown in FIG. In this connection structure, in order to improve the cleaning effect of the outer blade cleaning body 52, the engagement dimension between the connection groove 90 and the drive shaft 43 is set as follows, and the outer blade cleaning body 52 is impacted by the drive shaft 43. Can be driven back and forth. Specifically, as shown in FIG. 10, the left-right width B1 of the connecting groove 90 is set to be larger than the left-right width B2 of the drive shaft 43, but the difference between the width dimensions of both is set larger than the normal margin gap. .

  Normally, the drive shaft 43 and the connection groove 90 that are engaged and connected to each other are configured such that the left and right width B1 of the connection groove 90 is set to be the same as or slightly smaller than the left and right width B2 of the drive shaft 43. Often engaged with a press fit. The width dimension difference (B1-B2) in that case is generally set to about -0.3 to 0 mm. In the present invention, the difference in width dimension (B1-B2) is set to 3 to 3.5 mm, and when the vibrator 25 reciprocates, the outer blade cleaning body 52 is stopped near the end of the stroke of the drive shaft 43, and the impact is shocked. Can be driven back and forth.

  As described above, when the difference in the width dimension is deliberately increased, the outer blade cleaning body 52 is released from the driving force when the vibrator 25 reaches the end of the stroke and further moves by its own motion inertia force. However, since the resistance of the surrounding washing water is large, it does not move by the difference of the width dimension, and stops at a position slightly past the position where the driving force is released. In this state, the drive shaft 43 that has been reversed from the stroke end collides with the inner surface of the connecting groove 90. As a result, the outer blade cleaning body 52 is driven impactively near the end of the stroke of the drive shaft 43, and the cleaning water feeding action by the blade body 82 is moderated and the inner surface of the outer blade 19 is effectively cleaned. Can be done automatically.

  In the cleaning device configured as described above, the outer blade holder 13 removed from the head portion 2 is loaded into the outer blade holder mounting portion 62 of the cleaning case 50 and is mounted by the elastic engagement claw 61 provided on the bearing body 57. Hold. In this mounted state, the outer blade 19 covers the cleaning fins 72 of the outer blade cleaning body 52. Next, the cleaning case 50 is mounted on the holder mounting portion 12 of the head unit 2, and the cleaning case 50 is locked and held by the lock lever 33 provided on the head case 10 so as not to be separated. The tip of the bristle 64 of the inner blade cleaning body 51 at this time is in contact with the peripheral surface of the blade shaft 18 a of the inner blade 18 and the blade 18 b, and the connecting groove 90 of the drive body 73 is connected to the drive shaft 43 of the vibrator 25. Is engaged.

  After the cleaning case 50 is mounted on the head unit 2 as described above, the entire electric razor is laid down sideways or obliquely downward as shown in FIG. 12, and the cleaning water (tap water) is placed in the water flow windows 58a and 58b of the cleaning case 50. The switch 16 is turned on to start the motor 16 while flowing water (flowing water such as water). As a result, the inner blade 18 is rotationally driven, and at the same time, the vibrator 25 is reciprocated by the eccentric cam 24. As the motor 16 starts, the inner blade cleaning body 51 receives the rotational force of the inner blade 18 and rotates in the reverse direction, and the outer blade cleaning body 52 reciprocates in response to the reciprocating motion of the vibrator 25. The inner blade 18 and the outer blade 19 are simultaneously and forcibly cleaned by the inner blade cleaning body 51 and the outer blade cleaning body 52.

  The inner blade cleaning body 51 during cleaning rotates vigorously in the opposite direction to the inner blade 18 while the bristle 64 receives the rotational force of the blade 18b of the inner blade 18 and partially slips. By the sliding operation of the bristle 64 and the blade 18b at this time, the peripheral surface of the blade shaft 18a and the chips and sebum adhering to the surface of the blade 18b can be scraped off. In addition, due to the collision action of the cleaning water flowing in from the water flow windows 58a and 58b and the impact of the cleaning water splashed off by the inner blade 18, the dust and sebum adhering to the inner blade 18 and its surrounding structures are simultaneously removed. Can be washed away. The dust and sebum separated from the inner blade 18 and the like flow to the rear wall side of the main case 53 together with the cleaning water and are discharged from the water passage hole 59.

  Part of the cleaning water that has entered the cleaning case 50 flows into the outer blade holder 13 and flows between the outer blade 19 and the outer blade cleaning body 52. The cleaning water that has flowed in is stirred and splashed by the blade body 82 of the cleaning fin 72 that reciprocates and collides with the inner surface of the outer blade 19 that faces the front and rear edges of the blade body 82, and mainly the front wall of the outer blade 19 and Wash away the hair and sebum adhering to the rear wall. Incidentally, most of the dust and sebum adhering to the inside of the outer blade 19 tends to concentrate on the inner surface of the front wall and the rear wall of the outer blade 19 positioned below the rotation trajectory of the inner blade 18. Therefore, the outer blade 19 can be cleaned accurately by cleaning the front and rear walls facing the front and rear edges of the blade body 82.

  The flakes and sebum separated from the outer blade 19 flow into the flow gap E together with the cleaning water, and are forcibly shaken and stirred by the blade body 82 of the cleaning fin 72 that is reciprocally driven. Clean the inner surface of the curved wall. Since the dust and sebum contained in the cleaning water is discharged together with the cleaning water from the blade hole of the outer blade 19 having a mesh blade structure, it does not remain inside the outer blade 19. The fluff and sebum adhering to the front wall and the rear wall of the outer blade 19 may grow larger than the gap e. In such a case, the blade body 82 comes into contact with the fluff and sebum mass and is forced. It can be scraped off and can be washed by the water hammer effect of the washing water thereafter.

  The cleaning operation need not be performed while pouring running water, and may be cleaned by immersing the cleaning case 50 in cleaning water containing detergent stored in the container. In that case, the cleaning can be performed while the cleaning case 50 is filled with cleaning water. In addition, the detergent contained in the cleaning water is foamed with the inner blade 18, the inner blade cleaning body 51, and the outer blade cleaning body 52, and the sebum adhering to the inner blade 18, its peripheral structure, and the outer blade 19 is decomposed with the detergent. While cleaning more effectively. In addition, when increasing the amount of water to be poured to the cleaning case 50, the cleaning case 50 and the outer blade holder 13 are filled with cleaning water, and the inner blade 18, the outer blade 19 or the outer blade holder 13 is immersed. It can be cleaned effectively in the same manner as the state. Further, when cleaning is performed with the outer blade protection cap attached to the outer surface of the outer blade holder 13, stagnation of cleaning water on the inner surface of the outer blade holder 13 is promoted and cleaning can be performed effectively.

  Hereinafter, another embodiment of the cleaning apparatus according to the present invention will be described. In each embodiment of FIGS. 13 to 26, the structure and function different from the previous embodiment are mainly described, and the same members as those in the previous embodiment and the preceding embodiment are denoted by the same reference numerals, and the description is given. Omitted.

  FIG. 13 shows an embodiment in which a part of the cleaning fin 72 of the outer blade cleaning body 52 is changed. In this case, the front and rear edges of the blade body 82 are formed in an upwardly tapered shape from the lower end side toward the upper edge side, and the portions where the thicknesses are formed at equal widths are the upper edge of the blade body 82 and the upper part of the front and rear edges. I tried to limit it to Specifically, when the width dimension b1 of the upper edge of the blade body 82 and the upper part of the front and rear edges is 1.0 mm, the width dimension b2 of the lower end portion of the front and rear edges of the blade body 82 is 2.0 mm. As described above, according to the blade body 82 having the front and rear edges formed in a narrow shape, the blade body 82 is prevented from elastically deforming excessively due to the resistance of the cleaning water during cleaning, and the cleaning water is further effective. Can be shaken and stirred. Further, with the washing water splashed off by the blade body 82, the hairs and sebum adhering to the front and rear walls of the outer blade 19 can be washed away.

  14 and 15 show an embodiment in which the structure of the outer blade cleaning body 52 and the drive structure of the outer blade cleaning body 52 are changed. In this case, the right and left side walls of the main case 53 are extended upward, and the extended portion and the bearing body 57 constitute a groove-shaped outer blade holder mounting portion 62.

In a state where the outer blade holder 13 is mounted on the cleaning case 50, the tip of the bristle 64 of the inner blade cleaning body 51 is in contact with the lower peripheral surface of the stirring body 72. Therefore, in a state where the inner blade 18 is rotationally driven, the inner blade cleaning body 51 is rotationally driven in the reverse direction in conjunction with the inner blade 18, and the stirring body 72 is partially slipped in conjunction with the inner blade cleaning body 51. While being rotated in the opposite direction.

  The washing water that has flowed into the outer blade holder 13 is splashed around the agitator 72 by the rotating blade piece 94 to wash away the dust and sebum adhering to the front and rear walls of the outer blade 19. At this time, a very small part of the tip of the blade piece 94 comes into contact with the front and rear walls of the inner surface of the outer blade 19 and scrapes off the dust adhering to the contact portion. It is only a thing. The cleaning action by the stirrer 72 is mainly exerted by the scooping-off cleaning of the cleaning water by the blade piece 94, and the inner surface of the outer blade 19 can be extensively cleaned compared to the scraping cleaning. In addition, the rotational resistance of the stirring body 72 accompanying scraping is smaller than the rotational force by the bristle 64 of the inner blade cleaning body 51.

  The outer blade cleaning body 52 of FIG. 16 is configured by a stirring body 72 having a gear section in the same manner as in FIG. In addition, the rotational force of the inner blade cleaning body 51 is transmitted to the stirring shaft 93 via the gear transmission structure 96 provided between the bush 65 and the stirring shaft 93 so that the stirring body 72 can be forcibly driven to rotate. did.
