Description

Technical Field

[0001] The present invention relates to an electric hair clipper, and particularly to an electric hair clipper with an adjustable cutter head and a limiting comb and having waterproof function. Background Art

[0002] An electric hair clipper is a commonly used tool for trimming human hair or animal hair. A rechargeable electric hair clipper is internally provided with a rechargeable battery that supplies power, and there is no need to plug in a power cord during use, which is deeply favored by consumers. The structure of a rechargeable electric hair clipper generally includes a housing composed of an upper shell and a lower shell. An electric motor is provided inside the housing, a cutter head driven by the electric motor is provided at the front end of the housing, a PCB board and a battery are provided inside the housing, a power switch is provided on the front shell, and a charging plug is provided at the rear end of the housing. The electric motor, the battery, the power switch, and the charging plug are all electrically connected to the PCB board. For the convenience of use, most of the commonly available electric hair clippers on the market are equipped with a blade adjustment mechanism to adjust the position of the moving blade, or a limiting comb adjustment structure to adjust the position of the limiting comb, so as to trim hairs of different lengths. The existing electric hair clippers, whether using a blade adjustment mechanism or a limiting comb adjustment mechanism, have the following defects: The blade adjustment mechanism has high adjustment accuracy but a short distance, that is, it can only be adjusted on a limited short length of hair, and the adjustable range is small; while the limiting comb adjustment mechanism has a long adjustment distance but low accuracy. Therefore, these two adjustment mechanisms cannot take into account both the adjustment range and the accuracy; and the current electric hair clippers have poor waterproof performance. Summary of the Invention

[0003] Based on the above problems, the present invention provides a waterproof electric hair clipper with an adjustable cutter head and a limiting comb, which can simultaneously adjust the positions of the cutter head and the limiting comb, that is, it has a large adjustment range and high accuracy, and at the same time achieves a good waterproof effect;

[0004] The technical solution adopted is: A waterproof electric hair clipper with an adjustable cutter head and a limiting comb, including an upper cover, a lower cover, a cutter head assembly, a limiting comb adjustment mechanism, a semi-exposed cutter head adjustment mechanism, and a waterproof movement; the upper cover and the lower cover form a housing, the waterproof movement is installed inside the housing, and a cutter head assembly is installed at one end of the housing; a groove is opened on the lower cover; the limiting comb adjustment mechanism is installed on the lower cover; the limiting comb adjustment mechanism is fixed to the cutter head assembly;

[0005] The limiting comb adjustment mechanism includes a limiting comb, a limiting comb holder, a first gear block, and a spring; a spring seat, a buckle, and a second convex tooth are fixed on the first gear block. The spring seat is located between the buckles, and the second convex tooth is located on the other side of the spring seat; the first gear block is fixed in the groove of the lower cover through the buckle; a spring is placed on the spring seat; a chute is provided on the limiting comb holder, and the convex edges on both sides of the limiting comb are matched with the chute; there are also first convex teeth on both sides of the limiting comb, and the first convex teeth are buckled on the groove on one side of the limiting comb holder; the second convex tooth on the first gear block is engaged with the gear slot on the limiting comb;

[0006] The semi-exposed cutter head adjusting mechanism includes a rotating ring, a pushing block and a cutter head rotating frame; the inner surface of the rotating ring is provided with a track; the pushing block has a convex cylinder and is connected to the rotating ring; one end of the pushing block is connected to the cutter head rotating frame; a spring is installed on one side of the cutter head rotating frame, and the spring is connected to the moving cutter fixing piece; the moving cutter fixing piece is located below the moving cutter; the moving cutter can move on the cutter head assembly;

[0007] A groove is provided below the waterproof movement, and a second gear block is sleeved in the groove. A second spring is installed in the second gear block; the second gear block engages with the concave teeth on the rotating ring.

[0008] Furthermore, the track inside the rotating ring is irregular.

[0009] Furthermore, the second gear block is conical and hollow.

[0010] Furthermore, an elastic waterproof mechanism is installed on the waterproof movement.

[0011] The elastic waterproof mechanism includes a lamp window, a waterproof upper shell and a rubber ring; there is a groove on the waterproof upper shell, the lamp window is connected in the groove of the waterproof upper shell by ultrasonic welding, and the rubber ring is connected to the lamp window by a fixing piece with screws.

[0012] Furthermore, a wire hole is provided on the lower cover, a fixing block is fixed in the wire hole, and there is a waterproof ring between the wire hole and the fixing.

[0013] The structure of the present invention is simple and convenient to disassemble and assemble. By engaging the first gear block in the limit comb adjusting mechanism with the gear slots on the limit comb and pushing the limit comb adjusting mechanism, the position of the first gear block on the gear slots of the limit comb is changed, so as to change the distance between the limit comb and the cutter head assembly, and the required hair length to be cut is realized. The length adjustment range is large; at the same time, it is also possible to rotate the rotating ring in the semi-exposed cutter head adjusting mechanism, engage the second gear block with the concave teeth on the rotating ring, and cooperate the irregular track inside the rotating ring with the pushing block. When the rotating ring rotates, the pushing block pushes the spring on the cutter head rotating frame, the spring pushes the moving cutter fixing piece, and the moving cutter fixing piece pushes the moving cutter to move, changing the position between the moving cutter and the static cutter. The length adjustment accuracy is high, and the precise adjustment of the hair cutting length is realized. Description of the Drawings
