Abstract
A brush head for an electrically driven toothbrush includes a holding part (2) that provides at least one connecting element for mechanically coupling the brush head to the electric drive of the toothbrush, wherein the holding part (2) integrally forms a stud (4) defining a pivot axis (S) about which the brush head is pivotable, and a plate (6) which at its end facing away from the stud (4) carries at least one bristle bundle (8) which at its attachment-side end includes a thickening (14) formed by surface melting. For improving the brush head, a substantially disc-shaped bristle carrier (10) is connected to a holding part (2) and includes a bore that is penetrated by the bristle bundle (8).
Claims22
A brush head for an electrically driven toothbrush, comprising:
- a holding part (2) that provides at least one connecting element for mechanically coupling said brush head to the electric drive of said toothbrush, wherein said holding part (2) integrally forms a stud (4) defining a pivot axis (S) about which said brush head is pivotable and a plate (6) which at an end thereof facing away from said stud (4) carries at least one bristle bundle (8) which at an attachment-side end comprises a thickening (14) formed by melting a material forming the bristle bundles (8);
- and
- a substantially disc-shaped bristle carrier (10) comprising a bore that is penetrated by said bristle bundle (8) and being connected to said holding part (2),
- wherein said bristle carrier (10) is connected to said holding part (2) by a plastic material (24) inserted into an intermediate space (18) between said bristle carrier (10) and said holding part (2), and
- wherein the thickening (14) at the attachment-side end of the bristle bundle (8) is substantially surrounded by the plastic material (24).
A brush head for an electrically driven toothbrush, comprising:
- a holding part (2) that provides at least one connecting element for mechanically coupling said brush head to the electric drive of said toothbrush, wherein said holding part (2) integrally forms a stud (4) defining a pivot axis (S) about which said brush head is pivotable and a plate (6) which at an end thereof facing away from said stud (4) carries at least one bristle bundle (8) which at an attachment-side end comprises a thickening (14) formed by melting a material forming the bristle bundles (8);
- and
- a substantially disc-shaped bristle carrier (10) comprising a bore that is penetrated by said bristle bundle (8) and being connected to said holding part (2) by a plastic material (24) injection molded into an intermediate space (18) between said bristle carrier (10) and said holding part (2),
- wherein said plastic material (24) introduced into said intermediate space underlaps and overlaps said plate (6) or said bristle carrier, respectively.
A brush head for an electrically driven toothbrush, comprising:
- a holding part (2) that provides at least one connecting element for mechanically coupling said brush head to the electric drive of said toothbrush, wherein said holding part (2) integrally forms a stud (4) defining a pivot axis (S) about which said brush head is pivotable and a plate (6) which at an end thereof facing away from said stud (4) carries at least one bristle bundle (8) which at an attachment-side end comprises a thickening (14) formed by melting a material forming the bristle bundles (8);
- and
- a substantially disc-shaped bristle carrier (10) comprising a bore that is penetrated by said bristle bundle (8) and being connected to said holding part (2),
- wherein said bristle carrier (10) is connected to said holding part (2) by a plastic material (24) inserted into an intermediate space (18) between said bristle carrier (10) and said holding part (2), and
- wherein said bristle carrier (10) or said holding part (2) forms a spacer (20) which defines said intermediate space.
