The present invention relates to a multi-blade electric rotary razor which comprises a razor blade cartridge turned by a motor, and at least one pair of razor blade assemblies disposed at an equal-angle distance at the razor blade cartridge along a direction in which the razor blade cartridge rotates, at least one pair of razor blades (hereinafter referred to as first razor blades) being arranged in an overlapping manner at a predetermined distance at the razor blade assembly along a radius direction of the razor blade cartridge. The electric rotary razor of the present invention has a structure of a wet shaver where multiple razor blades are arranged, and uses the motor to turn the razor blade cartridge during shaving for user convenience and thorough shaving. The multi-blade razor blade assembly alleviates a dermal stimulation, minimizes a possibility of a scar, and does not require shaving cream, making shaving convenient and unhindered by time and space.

1. An electric rotary razor operated by a motor, the electric rotary razor comprising: a razor blade cartridge turned by a motor; andat least two razor blade assemblies disposed at an equal-angle distance at the razor blade cartridge along a rotary direction of the razor blade cartridge,wherein, the razor blade cartridge comprises:a bottom housing coupled to the motor to rotate depending on an operation of the motor;a holding part formed in a front surface of the bottom housing to accommodate razor blades;a top housing coupled to the bottom housing to surround a periphery of the bottom housing; anda housing cover coupled to a central portion of the bottom housing,the holding part is extended in a radius direction of the bottom housing,at least two holding parts are disposed along a circumference direction of the bottom housing,each of the razor blade assemblies comprises a first razor blade and a second razor blade disposed along a radius direction of the razor blade cartridge,each of the first razor blade and the second razor blade comprises razor blades arranged in an overlapping manner, andthe first razor blade and the second razor blade are disposed to face each other. 2. The electric rotary razor of claim 1, wherein, the razor blade cartridge rotates in a forward direction and a rearward direction, and the blades of the first razor blade or the blades of the second razor blade are disposed to face a rotary direction of the razor blade cartridge. 3. The electric rotary razor of claim 2, wherein the motor turns the razor blade cartridge in a forward direction or a rearward direction, or alternately turns the razor blade cartridge in a forward direction and a rearward direction. 4. The electric rotary razor of claim 1, wherein, the first razor blade or the second razor blade are disposed by a distance in the range of from 0.3 mm to 1.0 mm. 5. The electric rotary razor of claim 1, wherein, the first razor blade and the second razor blades are disposed on the same plane as a front surface of the razor blade cartridge, or disposed on a plane lower or higher than the same plane as the front surface of the razor blade cartridge by a range of 0.1 mm or less. 6. The electric rotary razor of claim 1, wherein, the top housing surrounds an end portion of the holding part in a position adjacent to an outer circumference surface of the bottom housing, the housing cover surrounds other end portion of the holding part in a central portion of the bottom housing, and thus, the razor blades accommodated in the holding part are fixed to the holding part. 7. The electric rotary razor of claim 1 further comprising: a coupling groove formed in an inner surface of the other end portion of the holding part; anda hooks extending from an inner surface of the housing cover to a lower portion, wherein, the hook is coupled to the coupling groove to fix the housing cover to the bottom housing. 8. The electric rotary razor of claim 1, wherein, the housing cover is manufactured of a material having lubricity. 9. The electric rotary razor of claim 1, wherein, the motor turns the razor blade cartridge in a forward direction or a rearward direction, or alternately turns the razor blade cartridge in a forward direction and a rearward direction. 10. The electric rotary razor of claim 9 further comprising: a circuit board on which a control circuit controlling the motor and a switch module are mounted, wherein, the motor is driven according to a control of the control circuit to control a rotary direction of the razor blade cartridge. 11. The electric rotary razor of claim 1 further comprising: a cartridge cover disposed for surrounding a periphery of the razor blade cartridge to move in a lengthwise direction of a rotary shaft of the razor blade cartridge, wherein, as the cartridge cover moves along the lengthwise direction of a rotary shaft of the razor blade cartridge, an end portion of the cartridge cover becomes closer to or farther away from a front surface of the razor blade cartridge. 12. The electric rotary razor of claim 1 further comprising: a spring providing the razor blade cartridge with elastic force operating in a lengthwise direction of a rotary shaft of the razor blade cartridge, wherein, the elastic force of the spring brings the razor blade cartridge into contact with skin with constant force to maintain the contact state. 13. The electric rotary razor of claim 1, wherein, the razor blade cartridge is replaced with other razor blade cartridge.
