Definitions

  • This invention relates to a motor-driven dry shaving device such as an electric shaver.
  • the device of this invention it is possible to continuously supplement and strengthen the electrical field effecting the accumulation of the hair dust on one of the two poles during the operation of the shaver, thus avoiding the above-noted deficiencies of previously known devices.
  • FIG. 2 shows a partial section of a dry shaving apparatus with rotary blades, according to this invention.
  • FIG. 3 is a cross-sectional view of the device of FIG. 2 taken along the section line 3-3 of FIG. 2.
  • a metallic cutting head frame 4 is attached onto the housing 7 of the dry shaver, this housing being of synthetic plastic material.
  • the cutting head frame carries a screen foil or perforated plate 8 as the external stationary cutting part.
  • the movable cutter component of the cutting head is formed by a frame 3 with several blades 6 attached thereto; this part is driven in a reciprocating movement by the rocking lever 9 of an oscillating-armature motor, the latter not being shown in detail.
  • a plate of insulating material, designated by 2 is provided on the part of the housing 7 in the proximity of the cutting head, and on one end of the blade block 3, 6, a brush 1 of Wool is attached.
  • the brush 1 slides along the plate 2, leaves the plate shortly before reaching the right terminal position illustrated in FIG. 1, and contacts the inner side of the metallic cutting head frame 4.
  • the previously electrically neutral plate 2 is negatively charged; the brush, so to speak, removes therefrom the positive charges and transfers them to the cutting head frame 4 as the ground pole.
  • an electrical field is produced between both parts which is continuously complemented and amplified during the operation of the shaver.
  • the hair dust collects on the negatively charged plate 2 and can be removed from the cutting head after the shaving procedure is done.
  • the frame 4 and the blade block 3, 6 can be provided with a cover of insulating material 5.
  • FIG. 2 includes a circular plate 2 insulating material with a recess Z'rz provided therein.
  • a brush 1' is mounted, being positioned to frictionally contact the plate 2' during the rotating motion of the blades.
  • the brush sweeps over the recess 2'a, it contacts a lug or contact surface 4'a of the metallic cutting head frame 4'.
  • the plate can be partially metallized in order to attain a charge concentration, and it can be additionally provided with an adhesive layer.
  • this plate can be mounted in the cutting head so that it can be detached therefrom in order to facilitate removal of the plate for discarding the hair dust.
  • the materials for the brush and the parts of the cutting head serving as poles can be selected appropriately depending upon at which location the hair dust is to accumulate.
  • An electric shaver with an electric field system for retaining hair dust in the cutting head comprising: a housing, a head frame, a cutting head and movable cutting blade element positioned on the housing Within the head frame, first insulating plastic pole means secured on the housing adjacent to the movable cutting blade, and second metallic pole means formed by the head frame spaced therefrom in the cutting head, and a sliding charge transport means attached to the cutting blade element for sequential contact With the first and second pole means for efiecting charge transfer therebetween and to thereby produce a charge separation between the first and second pole means, whereby the hair dust is retained by said electric field.
