摘要:
Disclosed is an electric toothbrush (1) comprising a handle part (2) and an attachment part (3), e.g. a bristle head (4). Preferably, the bristle head (4) can be driven by a first drive unit (6.1) encompassing a first electric motor (7.1). A reservoir (8.1) for a care substance is connected to a duct (11.1) extending into the bristle head (4) by means of a pump (10.1) which can be driven by a second drive unit (6.2) encompassing a second electric motor (7.2). The first and the second electric motor (7.1, 7.2) are powered by a disposable or a rechargeable battery (12). A housing (16) of the handle part (2) is subdivided into a first and a second chamber (19, 20) by means of a liquid-tight partition (17) that extends in the longitudinal direction of the handle part (2). The first and the second drive unit (6.1, 6.2) and the disposable or rechargeable battery (12) are arranged in the first chamber (19) while the reservoir (8.1) and the pump (10.1) are disposed in the second chamber (20). The pump (10.1) can be driven by the second drive unit (6.1) via a lever (15), pumping movements (A′-B′) being transmitted from the lever (15) to the pump (10.1) via an integrated soft membrane (18) of the partition (17) by means of non-positive contact or via a liquid-tight slide passage (21) in the partition (17).

An electric toothbrush is disclosed. The toothbrush includes a handle part and an attachment part, wherein the handle part has a housing, in which a reservoir for a care substance, a pump for delivering the care substance and a drive unit for driving the pump are arranged. The housing is divided into a liquid-tight first chamber and a second chamber by a partition extending in the longitudinal direction of the housing. The first chamber housing the drive unit is arranged in the first chamber and the reservoir and the pump are arranged in the second chamber.

The invention is directed to a beverage brewing apparatus having a water reservoir (1) and a pump (6) powered by an electric motor (45), the pump pressurizing water from the water reservoir (1) and delivering it to a flow-through heater (11) heated by an electric heater (14). In the flow-through heater (11), water is heated in a water conduit (13) and subsequently fed to a pressure chamber (35), adapted to be filled with coffee grinds, of a brewing unit (34) from which, following an extraction operation, the brewed coffee flows into a receptacle (38, 39). According to the invention, a valve device (20) opening when a predetermined pressure is exceeded is provided in the fluid path (9, 13, 15) between the flow-through heater (11) and the brewing unit (34). As a result, the water current delivered by the pump (6) and flowing through the flow-through heater (11) is maintained nearly constant, causing a uniform transfer of heat in the flow-through heater (11) and avoiding a standstill condition of the electric motor (45). This also keeps the temperature control of both the flow-through heater (11) and the water heated in the flow-through heater (11) at an approximately constant level.
摘要:
A filter for the filtration of extraction beverages includes a disk having a plurality of apertures through which the beverage extracted from the material to be extracted passes form the afflux side to the efflux side. Each aperture is formed by cut edges in the disk and by bending a cut edge away from the surface of the disk to form a roof-shaped dome. The filter is formed by a single punching, bending and embossing operation without scrap slug being produced.
