Description

Oil storage groove structure of comb-tooth-shaped cutter part of fixed cutter of electric hair cutter

Technical Field

The utility model relates to a serrated knife structure of electronic hair clipper especially relates to an upper surface at each serrated knife of the broach portion of the fixed sword of electronic hair clipper is equipped with the oil storage ditch structure of the broach portion of the fixed sword of the electronic hair clipper of independent indent oil storage ditch separately.

Background

Generally, the comb-shaped blade of the known electric hair cutter includes a fixed blade fixedly mounted at the front lower part of the electric hair cutter and a movable blade stacked above the fixed blade, and the movable blade above the fixed blade is driven by the internal power of the electric hair cutter to linearly and repeatedly move left and right, so as to achieve the effect of cutting hair by the comb-shaped blade part of the fixed blade and the comb-shaped blade part of the movable blade.

In the related art, in order to make the shearing action of the fixed knife and the movable knife stacked on each other smoother, the manufacturing industry designs an upwardly concave oil receiving groove (or called as an oil storage cavity) below the movable knife stacked above the movable knife and moved linearly left and right in a reverse reset manner, and the upwardly concave oil receiving groove is used for storing added lubricating oil, so that the movable knife has an oil lubricating effect when moving linearly left and right in a reverse reset manner, further the friction between the fixed knife and the movable knife is reduced, and the action is smoother.

However, since the lubricant is stored below the movable comb-shaped blade portion which is movable above the movable comb-shaped blade portion, the lubricant is discharged and consumed at a high rate and is lost due to the downward opening of the lubricant storage tank for storing the lubricant and the influence of gravity, and the number of times of adding the lubricant is increased.

Therefore, the inconvenience and trouble of how to improve the storage of the related lubricating oil, how to improve the loss of the related lubricating oil, and how to improve the frequent adding times of the related lubricating oil are the technical problems which are urgently solved in the manufacturing industry of the related electric hair clippers.

SUMMERY OF THE UTILITY MODEL

This technical scheme provides its creation aim at of oil storage ditch structure of comb-tooth form sword portion of stationary knife of electronic hair-clipper: the upper surface of each tooth cutter of the comb-shaped cutter part of the fixed cutter is provided with an independent concave oil storage groove, so that the better lubrication degree is generated between the fixed cutter and the movable cutter of the electric hair cutter, the trouble that the related lubricating oil is easy to lose is improved, the friction resistance is effectively reduced, and the actuating friction temperature and the cutter abrasion among the lubricating oil and the lubricating oil are reduced.

In order to achieve the purpose, the technical scheme is that the upper surface of each tooth cutter of the comb-shaped cutter part of the fixed cutter of the electric hair cutter is provided with an independent concave oil storage groove.

As a further improvement of the technical scheme, the two sides of the oil storage groove and the two sides of the upper surface of the toothed cutter are respectively provided with a distance of 0.15mm to 0.5 mm.

As a further improvement of the technical scheme, the inner width of the oil storage groove towards one end of the tooth cutter tip part is smaller than the inner width of the oil storage groove towards one end of the tooth cutter root part.

As a further improvement of the technical proposal, the oil storage groove has an inner groove depth of 0.03mm to 0.3mm, wherein the inner groove depth of the oil storage groove towards one end of the tooth cutter tip part is less than or equal to the inner groove depth towards one end of the tooth cutter root part.

As a further improvement of the technical scheme, the cross section of the oil storage groove can be shaped like ㄩ, U or arc.

As a further improvement of the technical scheme, the two ends of the oil storage groove, which face the tooth cutter tip part and the tooth cutter root part, on the upper surface of the tooth cutter are arc-shaped.

By arranging the independent concave oil storage groove on the upper surface of each tooth cutter of the comb-shaped cutter part of the fixed cutter, the electric hair cutter can achieve better lubrication between the fixed cutter and the movable cutter, improve the trouble that the related lubricating oil is easy to lose, effectively reduce the friction resistance, and reduce the friction temperature and the abrasion between the cutters.
