摘要： The invention relates to a spray nozzle (1) creating a liquid jet for a mouth rinse. Said spray nozzle (1) comprises a nozzle member (2) that is provided with a chamber (6) into which extends a liquid duct (5) supplying pressurized cleaning liquid. A nozzle outlet (18, 19) which discharges a jet of cleaning liquid extends from said chamber (6). The chamber (6) is connected to a whirl chamber (15) that has an approximately round cross section and creates a circulating flow of the cleaning liquid. The nozzle outlet (18,19) extends centrally from the whirl chamber (15) and comprises an approximately cylindrical narrow passage and an adjacent especially approximately conical expansion. The cleaning liquid is delivered to the spray nozzle at high pressure, the nozzle outlet creating a high-speed liquid jet of the discharged cleaning liquid, which consists of microsized drops.

摘要： The invention relates to a brush head for a toothbrush, which comprises a handle with a drive for said brush head. Said brush head has an, in particular, disc-shaped or plate-shaped bristle support, which supports a bristle array and which is displaceably mounted on a brush head support, and has connecting means for coupling to the drive of the toothbrush situated in the handle. The bristle support is subdivided into a number of bristle support segments that can move relative to one another. The brush head additionally comprises drive means that alter the position of the bristle support segments relative to one another according to the position of the entire bristle support. According to the invention, the drive means, which cause the bristle support segments to move relative to one another, comprise a curved control surface and an engaging element that interacts therewith, both of which being respectively provided on the brush head support and on at least one bristle support segment, in order to correspondingly displace this at least one bristle support segment when the bristle support moves about the movement axis thereof. The basic movement of the entire bristle support relative to the brush head support is utilized, via a cam surface, for additionally driving individual bristle support segments so that these individual bristle support segments execute an additional movement that is superimposed on the basic movement of the bristle support.
