摘要： A reciprocatory dry shaver is capable of providing a drive point of transmitting a reciprocating force to an inner cutter from a drive element at a location as close as to a cutting edge of the inner cutter for enhancing cutting performance, yet making the use of a plastic made drive element to give a detachable connection with the inner cutter. The shaver comprises a housing incorporating a drive source which is connected to move a drive element projecting on top of the housing. An outer cutter is supported to the top of the housing. An inner cutter is detachably connected to the drive element and is driven thereby to reciprocate in hair shearing engagement with the outer cutter. The drive element comprises a stud and a pin which projects beyond the upper end of the stud. The inner cutter is formed with a joint for detachable connection to the stud and with a catch for detachable connection to the pin. The catch is formed upwardly of the joint to define a drive point at the connection with the pin where the drive element transmits a driving force of reciprocating the inner cutter. With this arrangement, the driving point can be disposed closer to an upper cutting edge of the inner cutter than a connection point of detachably holding the inner cutter to the drive element. Consequently, a driving force is effectively applied for hair shaving between the reciprocating inner cutter and the outer cuter, thereby enhancing cutting performance.

摘要翻译： 往复式干式剃须刀能够提供一个驱动点，该驱动点从位于内切割器的切割边缘的位置处的驱动元件向内切割器传递往复力，以提高切割性能，但是使用塑料 使驱动元件与内刀具分离连接。 该剃须刀包括一个外壳，该外壳包括驱动源，该驱动源连接以移动突出在外壳顶部上的驱动元件。 外刀片支撑在外壳的顶部。 内刀片可拆卸地连接到驱动元件，并由此驱动从而与外刀具进行头发剪切接合。 驱动元件包括螺柱和突出超过螺柱的上端的销。 内切割器形成有用于可拆卸地连接到螺柱的接头和用于可拆卸地连接到销的接头。 卡扣在接头的上方形成，以在与销的连接处限定驱动点，其中驱动元件传递内铣刀往复运动的驱动力。 通过这种布置，驱动点可以比可拆卸地将内刀片连接到驱动元件的连接点更靠近内刀片的上切割刃布置。 因此，在往复式内刀具和外切刀之间有效地施加驱动力，从而提高切割性能。

摘要： An improved hand-held motor-driven oscillating razor for wet shaving provides a substantially vibration-free gripping during the shaving. The razor comprises a grip housing adapted to be gripped by the hand of a user and a shaver head movably supported on top of the grip housing. The shaver head carries a razor blade element and includes a weight which is driven by a motor to impart oscillatory movement to the shaver head. The motor is mounted within the shaver head together with the weight so as to confine an oscillatory system within the shaver head. A damper member is utilized to singly support the shaver head to the grip housing in order to made the shaver head movable with respect to the grip housing such that the grip housing can be isolated substantially from the oscillatory system in the shaver head, permitting the shaver head to oscillate substantially indpendently of the grip housing, thereby minimizing a counter-vibration transmitted back to the grip housing from the shaver head. The damper member is preferably configured to exhibit different elasticity in differing directions in order to minimize the counter vibration which the user feels during the shaving, while assuring effective shaving.
