A nozzle structure with a plurality of bristle bunches includes a mouth-shaped casing and a plurality of bristle bunches. The mouth-shaped casing has a first end portion with an air inlet and a second end portion opposite to the first end portion. The second end portion has a plurality of outlet pores arranged in parallel and a plurality of bristle pores. Each of the outlet pores connects to the air inlet via a ventilated space inside the mouth-shaped casing, and the plurality of bristle bunches are implanted in the bristle pores of the mouth-shaped casing. In addition, the bristle bunches protrude further out from the outlet pores.

A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

A brush head (32) including a neck (40) having a brush neck (42); a plurality of bristle tufts (21), each of which includes a plurality of bristle strands with a free end (25) and a proximal end (23), the proximal end having a proximal end head portion (26); a plurality of retention rings (50), each configured to receive the proximal end of at least one of the plurality of bristle tufts; an elastomeric matrix (30) bonded to at least a portion of the brush neck, the plurality of retention rings, and the proximal end of the plurality of bristle tufts, wherein the proximal end head portion of each of the plurality of bristle tufts is configured to comprise a space (27) between the proximal end head portion and the respective retention ring.

In the technical field of the production of brush production machines (1), a construction kit for the production of brush production machines (1) is inter alia provided. This modular construction kit includes at least one basic module type (2a) and a deflection module type (3a), the modules (2, 3) thereof having standardized connection interfaces 5 by which the modules (3) are inter-coupleable to form a brush production machine (1). Since each of the modules (2, 3, 4) is coupleable to each module of the different module types (2a, 3a, 4a), a large number of different brush production machines (1) can be configured by way of this construction kit, without a particular constructive effort being required to this end.

A head for an oral care implement has a mounting surface comprising at least one tuft of a first length and at least one tuft of a second length, the first length being longer than the second length measured from the mounting surface of the head along a longitudinal axis of the tufts. The at least one tuft of the first length comprises filaments having a substantially circular cross-sectional area extending in a plane perpendicular to the longitudinal axis and an end-rounded free end, while the at least one tuft of the second length comprises flagged filaments having split free ends.

The present invention is a makeup brush with a releasably connectable ferrule and handle, so that the ferrules and handles are interchangeable. The means for releasably connecting the ferrule and the handle may be, for examples, by friction fit or by the inclusion of sliding features, such as a notch and channel, such being additional methods for releasable connectivity beyond those already patented and/or developed by the inventor.
