A drive assembly is disclosed, including a housing cylinder with a cap end, an attachment end with a first attachment surface, and gear teeth disposed around an inner circumference to form at least one ring gear. A planetary gear set may be surrounded by the housing cylinder and includes at least one sun gear and at least one set of planet gears. An output interface may include an interface body and an annular attachment lip with a second attachment surface. The housing cylinder may be attached to the attachment lip for operation of the drive assembly via the second attachment surface contacting the first attachment surface, with the cap end of the housing cylinder extending axially past an axial end of the attachment lip. Rotational power may be transmitted from the planetary gear set to the output interface via the gear teeth and the contact between the attachment surfaces.

A control module for a motorized powered surgical tool. The module includes a trigger sensor, a motor rotor position sensor and control circuit. The trigger sensor and motor rotor position sensor output their signals by monitoring magnetic fields associated with, respectively the trigger and the motor rotor. Based on signals from the trigger sensor and the motor rotor position sensor, the control circuit selectively applies energization signals to the windings of the motor. The module includes a shell that separates the trigger sensor, the motor rotor position sensor and the control circuit from the motor. The shell is formed from material that both shields the components within the shell from affects of the ambient environment and that allows the magnetic fields to be detected by the sensors.

A drinking system (1) is disclosed which comprises a drinking vessel (2) with a receiving chamber (3) for a liquid. A drinking straw (5) is arranged in the drinking vessel (2) and is guided into the receiving chamber (3). The drinking system (1) further comprises a fragrance reservoir (9, 9) which is loaded with fragrance and has an inflow opening (10) for air and an outflow opening (11) for fragrance-enriched air. The drinking straw (5) is connected or connectable to the outflow opening (11) in order to suck in fragrance-enriched air emerging from the outflow opening (11) of the fragrance reservoir (9). According to the invention, an injector pump arrangement (12) is provided in the drinking system (1), which injector pump arrangement (12) is connected to or integrated into the drinking straw (5) and is joined to a suction channel (8) of the drinking straw (5) by way of a main flow path which is surrounded by an outer wall, or is a component of the suction channel (8). The injector pump arrangement has a suction opening (17) which is led through the outer wall and is fluidically connected or connectable to the outflow opening (11, 11) of the fragrance reservoir (9, 9). It further comprises the following components: a drive nozzle (14), an expansion chamber (15) which is fluidically connected directly downstream of the drive nozzle (14) and into which the suction opening (17) leads, and a collector nozzle (16) which is fluidically connected directly downstream of the expansion chamber (15).

A handheld, hand-operated blender may include a container, a lid threadably connected to an upper portion of the container, a bottom portion including a stationary bottom portion threadably connected to a lower portion of the container and a rotatable bottom portion rotatable with respect to the container. The blender may also include a blade assembly including a plurality of blades and a shaft rotatably connected to the rotatable bottom portion and a gear assembly mechanically connected to the blade assembly and the rotatable bottom portion such that rotation of the rotatable bottom portion rotates the blade assembly at a faster revolution per minute than the rotation of the rotatable bottom portion.

A dry powder and liquid mixing apparatus provides a dry powder container integratable with a liquid container, and a lid engaging both the dry powder container and the liquid container to enable selectable storage and mixing of powder and liquid, such as mixing dry infant formula with water. Through simple manual twisting of the lid about the liquid container to a closed state, a user is able to selectively prevent mixing of stored dry powder and liquid. Likewise, through simple manual twisting of the lid about the liquid container to an opened state, a user is able to selectively enable mixing of the dry powder with the liquid, by shaking the apparatus while the lid is in an opened state, resulting in a consumable mixed formula.

A lid closure for storing and dispensing at least one material into a hot or cold beverage container comprising a one-piece molded lid closure with one or more sealed compartments containing one or more materials, and a stirring element integrally molded to the lid, wherein the sealing floor of the compartments is broken by pulling the stirring element and therefore, the materials are dispensed to the beverage container, where they are then mixed with the stirring element to provide an instant beverage, preferably instant coffee.

This disclosure presents a reptile cricket powder mixer, which comprises a shell, including a primary shell with primary through-holes provided on its lower surface at an interval and a secondary shell which is movably mounted at the lower end of the primary shell and is used to store calcium powder; an upper cover, which is mounted at the upper end of the primary shell; a powder adjusting ring, which is fixed inside the secondary shell, and secondary through-holes are provided on the surface of the ring at an interval aligned with the primary through-holes. In this disclosure, by rotating the secondary shell, you can change the area of alignment of the primary through-holes with the secondary through-holes, so as to control the quantity of the powder entering to or from the first or the secondary shell, or to conveniently recycle any excessive powder in the primary shell.

A cup structure includes a bottom, a body and a top cover. A bottom edge of the body is detachably sleeved at the bottom. The top cover is covered on a top of the body. The bottom includes a base, a driving assembly, a transmitting assembly and a cover. A top surface of the base is sunk inward and forms an accommodating space. The driving assembly is disposed in the accommodating space. The transmitting assembly is geared into the driving assembly. The cover is disposed on the transmitting assembly, wherein the cover includes a protrusion, a water-blocking layer and a mixer. The mixer is disposed on a top of the protrusion and includes at least one mixing blade. A power is transmitted to the mixer by the transmitting assembly after the power is generated by the driving assembly, so that the at least one mixing blade is rotated.

A beverage apparatus hand-holdable by a user to be portable, can include a beverage chamber housing that includes a chamber for storing a consumable liquid. The beverage apparatus can include a dispensing assembly that includes a receptacle. The receptacle can retain a vessel. The vessel can include an electronic tag and can contain an additive. The dispensing assembly can be operatively controllable by a controller to output the additive from the vessel into the consumable liquid. The beverage apparatus can include one or more sensors, devices, or assemblies that can be used to detect a volume of liquid in the chamber or a liquid level in the chamber. The beverage apparatus can include an apparatus computer processor portion (ACP) and an apparatus database portion.
