An ergonomic, electric can opener sits squarely on a kitchen counter and has working features such that the user need not turn the opener to see where to place the can. The housing and working features of the can opener are situated at about a 45 degree angle to the front of the kitchen counter, and a person using the can opener can easily see both an operating lever and a place to insert the can for opening. The can opener is advantageous to persons with arthritic conditions, requiring no orientation in a preferred direction by a user, a minimum of force to operate, and automatic stopping.
An electromotive can opener comprises a body. The body is formed by a first half and a second half. A motor, a touch switch for actuating the motor, a high twisting gear set, and a cutter handle are assembled to the body. In the high twisting gear set, a plurality of following gears and driving gear are engaged one by one and then is engaged to a driven shaft. The driven shaft is assembled with a driving gear. A knife protrudes out of a cutter handle. In operation, the knife cuts into the can and the touch switch is pressed by the cutter handle to actuate the motor and the shaft is driven. The can is driven to rotate to be cut along the periphery by the knife; and high twisting gear set formed by the plurality of gears provides a high twisting force for securing the can firmly.
A battery-operated can opener includes a DC motor, a battery, a switching lever that controls electric connection between the battery and the DC motor, an actuating arm coupled to the switching lever for moving a cutter out of the can opening for cutting the lid of a can when switching on the DC motor, a guide gear wheel coupled to the DC motor through a transmission gear set for moving the can opener along the rim of the can to force the cutter to cut open the lid of the can.
