A powder output device, including powder storage device (1), powder dispersion device (2), powder distributor (3), and a power device (4) connected with powder dispersion device (2) and powder distributor (3). The powder distributor (3) includes a rotatory accessory (31), a main shaft (32), a shell (33), an output groove (35), and a feed inlet (39). The main shaft (32) is positioned horizontally. The rotatory accessory (31) sleeves on the main shaft (32) and is in the shell (33). At least one recess (312) corresponding to the output groove (35) and the feed inlet (39) is provided on the rotatory accessory (31). Beneficial effects include: facilitating fast and efficient distribution of powder, resulting in not too much powder piled up at the bottom, creating less waste, and can determine the amount of powder to be distributed according to needs, so that the output quantity can be controlled, and the output amount of powder is consistent every time.

A grinding device includes: a housing that includes a sidewall; a grinding bowl within the housing; a cover that mates with one of the housing and the grinding bowl, wherein the cover together with the grinding bowl defines a grinding chamber; a blade positioned within the grinding chamber; a motor, positioned within the housing, operatively connected with and configured to rotate the blade; and a dial generally radially aligned with the sidewall of the housing, wherein the dial is configured to control at least one operational parameter of the motor; and wherein the dial rotates around a substantially vertical axis.

The present invention is directed to a hand-held modular kitchen multitool having a universal powerhead capable of being used with a variety of kitchen appliance attachments, such as a can opener and a coffee grinder. The can opener is a side cutting can opener which provides a more compact size and smoother cut. The coffee grinder has a rotating blade that's only operational when enclosed by a cup and assembled with the powerhead. This prevents unintentional operation and injury to the user.

Disclosed is a coffee grinder having improved accuracy of burr alignment for grinding uniformity. The coffee grinder having improved accuracy of burr alignment for grinding uniformity of the present disclosure comprises: a lower flat burr carrier having a rotary base part rotatably coupled to a grinder body and a lower flat burr part coupled to the rotary base part so as to rotate together with the rotary base part and having a first grinding blade; and an upper flat burr carrier that is coupled to a fixed coupling part provided on the grinder body and grinds introduced coffee beans together with the first grinding blade, wherein the lower flat burr part is coupled to the side of the rotary base part.

A coffee grinder is provided that includes one or more blades; a motor coupled to the one or more blades to drive rotation of the one or blades; and a grind controller that receives a supply voltage; receives a grind setting corresponding to a particular particle distribution; and controls RMS voltage, duty cycle, activation pulse frequency, and overall duration of a grind time of the supply voltage for activation of the motor based on the grind setting, wherein the grind controller generates, from the supply voltage, an adjusted voltage signal of a constant RMS voltage that is supplied to the motor during activation pulses occurring during the overall duration of the grind time to complete operation of the grind setting.
