In order to achieve optimized handling and a smooth-running mechanical system, which enables a minimized drive, it is proposed that the cutting plane (16) form an angle (18) of from 10 to 70 degrees, or preferably of from 20 to 30 degrees, with the longitudinal axis (17) of the gripping piece (2), and that the sliding block (11) be designed in the form of a cylinder (19) that extends in the direction (15) indicated or in the form of a ball (20).

Description

The electric hair cutter

Theme of the present invention relates to the electric hair cutter in beauty culture and the sector.

Invention field

The electric hair cutter be people fully known to.They are used for cutting hair of scalp and be the alternative replacement scheme that adopts scissors to come the cutting hair.

United States Patent (USP) 5,959,878 disclose a kind of cutting machine of mowing in the lawn that is used for.If make its size and cutting accuracy be suitable for hairdressing requirement already, then its actuation techniques can be used in the hair salon.This electric slicer be equipped with grasping member (it has longitudinal axis and driver), fixing cut paring blade, be parallel to and adjoin described fixedly cut the paring blade alignment and can be on cutting planes before and after mobile paring blade and the transmission device cut, this transmission device is delivered to rotatablely moving of power transmission shaft and movably cuts paring blade.Power transmission shaft has the reversing arrangement that comprises eccentric and converts linear seesawing to so that will rotatablely move.Can reversing arrangement be connected to movably around the reverse arm of reach rotation and cut on the paring blade.The disk of slide block form is attached on the bearing pin on the eccentric, and wherein said slide block is maintained fixed by the retainer on the reverse arm end, and the design retainer is on the direction perpendicular to power transmission shaft, makes slide block carry out on this direction and moves up and down.

DE 103 38 401 A1 disclose a kind of hair cutter from hairdressing place's industry, and the longitudinal axis of wherein said shear plane and grasping member forms the angle between 10 ° and 70 °.This angle makes to be handled and operation easily.

Background of invention

Known systems has following shortcoming: for also maneuverable electric hair cutter, do not have concrete special location and reversing arrangement smoothness run.Therefore, United States Patent (USP) 5,958, the driving force of 878 subject requirement higher amount, and the theme of DE 103 38 401 A1 has the not too accurate reversing arrangement of operation.

Target of the present invention is the theme that further develops the preorder of claim 1 to a certain extent, makes the shortcoming of being mentioned be eliminated.

Summary of the invention

The present invention has realized described target, and wherein the longitudinal axis of cutting planes and grasping member has formed 10 ° to 70 ° angle, and described slide block is designed to perpendicular to the upwardly extending cylinder form in the side of power transmission shaft or be designed to the form of spheroid.

Hair cutter of the present invention has following advantage: it has favourable angle, because described angle is between 10 ° and 70 °.If described angle is between 20 ° and 30 ° then be preferred, between 20 ° and 25 °, be particularly preferred wherein, make this angle to get a haircut, basically with to shear hair with scissors corresponding, and this is attended by the favourable operability of the ergonomics that is suitable for using and functional.Driving force (it is the size of finger actuator and service time of battery randomly) is minimized, because reversing arrangement accurately and valuably transmits the power that will transmit, and therefore transmits power in the mode of low wearing and tearing.Therefore, transmit power, become cylinder to be fit to slider designs in order to guarantee safety and low wearing and tearing ground.Slide block can have and is the boring of knowing pattern, insert bearing pin in boring, and wherein slide block is connected on the bearing pin with rotation mode.

The favourable embodiment of the innovation of being advised is described in the claim 2 to 8.

If slide block is designed to have the cylinder of at least one flat spot (A2), then this can cause multiple advantage.On the one hand, the groove that is provided on cylindrical outer surface (it is along cylindrical whole length wearing and tearing) is used for limiting concrete position reference, and described position reference can be used to calculate relative motion.On the other hand, cylindrical non-straight surface area is used for the concrete location transmission of power.The flat spot (A3) that is transverse to the central axis of bearing pin has the following advantages, that is, it does not change for motion transmits very important cylindrical any surf zone.Identical situation is applicable to the flat spot (A4) of the central axis that is parallel to bearing pin.When the flat spot (A5) that has the flat spot that is transverse to central axis and be parallel to central axis, the transmission that can especially accurately produce slide block and power is optimized.When slide block is remained on the end of reverse arm, considered each flat spot, if and slide block is remained in the retainer by the profile fastener on the curved surface of slide block according to A6, then flat spot will not interfered rotatablely moving of reverse arm, and slide block can be along pin slide.

In principle, slide block can be maintained fixed in retainer and can be along pin slide.Alternatively, implementer's case can be designed so that also slide block can move in retainer, and slide block be installed on the bearing pin (12) on the bearing of trend of reverse arm with fixed form.

This embodiment is suitable for slide block and is spherical form and slide block both of these case in the form of cylinders.In this embodiment, if the flat spot of the wall that is parallel to retainer is not provided, then according to A8, retainer has parallel to each other at two walls that extend and adjoin slide block on the direction of reverse arm on both sides relatively, wherein has the gap between slide block and wall.When reverse arm is positioned at the center, promptly when its complete matching, described gap maximum.In addition, if about reverse arm rotates to greatest extent the time, the gap is zero, and then this can cause described driving to be delivered to movably by the most accurately cutting on the paring blade.
