The present patent discloses an electric grinder, comprising a shell, a motor assembly, a grinding assembly and a dust cover. The motor assembly and grinding assembly are provided in the shell, and an opening is provided at one end of said shell. The dust cover comprises a cover and a counterweight part, and can open or close the opening of the shell under the gravity of the counterweight part. In the electric grinder provided by the present invention, when the opening of the grinder faces downward, the dust cover can open automatically. When the opening of the grinder faces upward, rotating the dust cover can close and engage with the opening of the dust cover automatically. Thus, the present invention prevents the feed opening of the electric grinder from being exposed to air when the user forgets to close the dust cover.

A kitchen appliance for processing food includes a housing, in or on which a drive unit is arranged for driving a processing tool for processing food. The kitchen appliance also includes an actuating mechanism for actuating the drive unit, wherein the actuating mechanism has a moveable switching element arranged outside of the housing. A switch is arranged inside the housing and an opening passes through the housing. The switch is switchable with the switching element for actuating the drive unit such that the switching element is moved relative to the switch, and the kitchen appliance has a sealing element, which forms a seal while closing the opening and transfers the movement of the switching element to the switch.

A dispensing device for dispensing material. The dispensing device comprises a dispensing head; a capsule magazine including at least one void; at least one material capsule, wherein the at least one material capsule is disposed within the at least one void in the material capsule magazine; a motor, operable to provide mechanical power for material dispensing operations, wherein the motor is disposed within the dispensing head; and a gear mechanically connected to the motor, wherein the gear is further disposed in connection with the at least one material capsule, such that operation of the motor causes rotation of the gear and, in turn rotation of the at least one material capsule.

A coffee machine including a grinder configured to grind coffee beans, and a coffee machine devised to be able to bring an air volume for separating waste such as chaff as close as possible to a target air volume. A first grinder configured to grind coffee beans; a fan configured to generate a wind pressure by rotating to separate waste from the ground beans ground by the first grinder; a fan motor configured to cause the fan to rotate; and a control unit configured to control rotation of the fan motor according to a set value, and the control unit acquires information (the number of rotation pulses) related to a rotation speed of the actually rotating fan motor, corrects the set value based on the acquired information, and controls the rotation of the fan motor according to the corrected set value.

An apparatus for grinding coffee is described. The apparatus includes a mechanical user input device, a grinding unit for grinding coffee, an electrical switch which connects the grinding unit to a source of electrical power and a mechanical coupling for the mechanical coupling of the user input device to the grinding unit. The user input device provides electrical power to the grinding unit when it is displaced from an initial position and ceases the provision of electrical power to the grinding unit when it is in the initial position. The mechanical coupling returns the user input device to the initial position when the grinding unit is operational.

A rocker arm structure of a hand-operated bean grinder includes a crank rocker arm and a folding mechanism. The crank rocker arm has first and second sections of rod body, and the folding mechanism is assembled between the first and second sections of rod body. The folding mechanism includes a first and second bodies assembled with each other. A spring is assembled between the first and second rod bodies, and a guide rail seat and a guide pin are respectively arranged on the first and second bodies. The guide rail seat is arranged on the second assembly port, and is arranged with a guide rail, a positioning groove, and at least one assembly notch. The guide rail has a position for guiding the first section of rod body to rotate 180 degrees from the position to be ground.
