Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing equipment, in particular to an electric hair clipper. Background Art

[0002] Electric hair clippers are commonly used in haircuts and are frequently used in barbershops because of their ease of operation.

[0003] At present, a Chinese patent with announcement number CN210757858U discloses an electric hair clipper, which includes a shell, a cutter head assembly, a driving mechanism and an adjusting mechanism. The driving mechanism is arranged in the shell, and the cutter head assembly is arranged at the front end of the shell. The cutter head assembly includes a fixed blade and a movable blade. The movable blade and the fixed blade are relatively slidably matched. The driving mechanism can drive the movable blade to slide along the width direction of the fixed blade, and the adjusting mechanism can drive the movable blade to slide along the length direction of the fixed blade. A cutter head spring is also arranged in the shell, and a supporting part is also arranged on the cutter head spring. The supporting part is buckled on the shell, and a spring mounting seat is also arranged in the shell.

[0004] When the electric hair clipper is in use, the driving mechanism drives the movable blade to slide along the width direction of the fixed blade to cut the hair. The movable blade is pressed against the fixed blade by the cutter head spring, which is convenient for quickly cutting the hair. Although the rotating part of the cutter head spring is positioned by being embedded between the spring mounting seat and the housing, so that the rotating part of the cutter head spring is not easy to escape from the gap between the spring mounting seat and the housing during daily use, since the lower side of the cutter head spring is not blocked, when the entire hair clipper is hit by a large external force, such as hitting the ground or a table, the rotating part of the cutter head spring is easy to escape from the groove formed by the spring fixing seat and the housing, thereby affecting the pressing force between the movable blade and the fixed blade, affecting the haircutting effect of the hair clipper, and reducing the impact resistance of the electric hair clipper. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an electric hair clipper, which has the function of preventing the position of the rotating part of the cutter head spring from changing easily when the hair clipper is hit, and the cutter head spring can more stably provide a pressing force to the movable cutter head.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric hair clipper comprises a shell assembly, a switch is provided on the front side of the shell assembly, a motor and a battery are provided in the shell assembly, the upper end of the motor passes through the shell and is connected to a cutter head assembly, the shell assembly comprises a front shell and a rear shell connected by bolts, the cutter head assembly comprises a fixed seat and an eccentric shaft, the front shell of the fixed seat is fixedly connected, the eccentric shaft is connected to the motor shaft, a push block is provided on the upper side of the eccentric shaft, a yield groove matching the motor shaft is provided on the push block, a push plate is fixed on the upper side of the push block, a moving cutter head is connected to the upper side of the push plate, a fixed cutter head fixed to the fixed seat by screws is provided on the upper side of the moving cutter head, a limiter is clamped on the outer side of the fixed cutter head, a cutter head spring is provided on the lower side of the push plate, the cutter head spring comprises a swivel portion, a connecting head and a positioning portion, a positioning groove for embedding the swivel portion and an auxiliary groove for embedding the positioning portion are provided in the fixed seat, and a card groove for embedding the positioning portion is provided on the push plate.

[0008] The utility model is further configured as follows: a limit block is provided at the lower end of the fixed seat, a limit groove is provided on the rear shell body for the limit block to be embedded in, two positioning columns are fixed on the side of the rear shell body facing the front shell body, an extrusion plate is sleeved on the positioning columns, an arc-shaped extrusion portion is provided at the upper end of the extrusion plate, and an extrusion seat is provided on the front side of the fixed seat.

[0009] By adopting the above technical solution, when the fixing seat is installed, the rear part of the fixing seat is restricted by the limiting groove, and the front side of the fixing seat is pressed down by the extrusion part. The fixing seat is firmly connected to the rear shell body and is not easy to shake. When the rear shell body is separated from the front shell body, the fixing seat can be separated from the rear shell body, making it more convenient to disassemble and assemble the fixing seat.

[0010] The utility model is further configured as follows: a first mounting groove and a second mounting groove are provided at the front and rear sides of the auxiliary groove, an auxiliary rod is rotatably connected in the first mounting groove, and a positioning magnet is embedded in the second mounting groove.

[0011] By adopting the above technical solution, when the fixing part is embedded in the auxiliary groove, the auxiliary rod can be turned over to cooperate with the positioning magnet, so that the fixing part is covered by the auxiliary rod, which facilitates the connection of the fixed blade head with the fixing seat.

[0012] The utility model is further configured as follows: the push plate is provided with two extension columns, the extension columns are passed through the movable cutter head, and the clamping grooves are arranged in the extension columns.

[0013] By adopting the above technical solution, after the positioning part is embedded in the auxiliary groove, the auxiliary rod can be flipped to cooperate with the positioning magnet, so that when people fix the fixed blade head and the fixed seat with screws, the positioning part located in the auxiliary groove is not easy to fall out of the auxiliary groove to interfere with the installation of the fixed blade head, thereby making it easier to install the fixed blade head and the fixed seat.

[0014] The utility model is further configured as follows: an L-shaped clamping platform is fixed on the upper side of the push plate, a bottom plate is fixed on the rear side of the clamping platform, the movable cutter head comprises a bottom plate, a cutting head is arranged on the front side of the bottom plate, a limiting foot abutting against the fixed cutter head is arranged on the rear side of the bottom plate, a reinforcing groove is arranged on the bottom plate for the clamping platform to pass through, and a portion of the bottom plate is embedded between the clamping platform and the push plate.

[0015] By adopting the above technical solution, the bottom plate is embedded between the clamping platform and the push plate, and the limiting foot is in contact with the fixed blade head, so that the movable blade head is more stable when sliding and is not easy to tilt back and forth, thereby improving the haircutting effect.

[0016] In summary, the utility model has the following beneficial effects:

[0017] The rotating part and the positioning part of the cutter head spring are embedded in the fixed seat and are closed by the movable cutter head, so that when the hair clipper is hit, the rotating part and the positioning part are not easy to fall out of the fixed seat, thereby making the position of the cutter head spring more stable. After the hair clipper is hit, the cutter head spring can stably provide pressing force for the movable cutter head, thereby making the performance of the hair clipper more stable.
