The present application provides an electric hair clipper, as shown in fig. 1, including a housing 100, a driving unit, a shaver 200, a fan 140, and a shaving unit; an accommodating cavity and an air duct are formed in the housing 100; the accommodating cavity is communicated with the atmosphere; the drive unit is located within the receiving cavity and is configured to drive the shaver 200 and the fan; the housing 100 includes a front end and a rear end and defines a front-to-rear direction; the front end of the shell 100 is provided with an inlet, and the rear end is provided with an outlet; the duct extends from the inlet to the outlet in the front-rear direction; the chip collecting unit is detachably connected with the rear end of the shell 100 and is communicated with the air duct through the outlet; the fan 140 is configured to promote air flow within the air duct and the receiving cavity to the debris collecting unit. The utility model provides an album bits unit adopts outer hanging structure, connects with shell 100 detachably, does not receive the restriction of electronic haircut device shell 100 volume, can select the collection bits bag 300 of suitable capacity according to demand and use scene, avoids frequently shutting down and emptys garrulous sending, improves the in-service use and experiences. While the debris collection bag 300 is used to collect the shredded hair in this embodiment, in other embodiments, the flexible conduit 400 may be directly connected externally to guide the shredded hair to the ground or other storage device, such as a trash can.

On the basis, the air channels comprise a front section air channel 110 close to the front end of the shell and a rear section air channel 120 close to the rear end of the shell; when the fan 140 is operated, air flows from the inlet to the scrap collecting unit through the front air duct 110, the rear air duct 120 and the outlet, and negative pressure is formed at the inlet to suck the crushed hair into the air duct and finally guide the crushed hair into the scrap collecting unit.

On the basis, as shown in fig. 1, the volume ratio of the front section air duct 110 to the rear section air duct 120 is 1:2-1:3; the ratio of the length of the front section air duct 110 in the front-back direction to the length of the rear section air duct 120 in the front-back direction is 4:1-5:1. When the fan 140 operates, the air in the rear air channel 120 is discharged from the outlet, and simultaneously the air in the front air channel 110 and the accommodating chamber is sucked into the rear air channel 120, so as to drive the air at the inlet to drive the hair cut by the shaver 200 to enter the front air channel 110. The volume ratio of the front-stage air duct 110 to the rear-stage air duct 120 can affect the suction force at the inlet, in this embodiment, the volume ratio of the front-stage air duct 110 to the rear-stage air duct 120 is 1.25, and the length ratio of the front-stage air duct 110 to the rear-stage air duct 120 in the front-rear direction of the housing 100 is 4.5. In other embodiments the volume ratio may be 1:2 or 1:3 and the length ratio may be 4:1 or 5:1.

On the basis, as shown in fig. 1, the accommodating cavity wall is provided with an air hole 111; the air hole 111 is configured to communicate the front section air duct 110 and the accommodating cavity; when the fan 140 operates, the air in the front air duct 110 flows into the accommodating cavity through the air holes 111, and the air in the accommodating cavity flows to the rear air duct 120. Besides being directly flowed to the rear-section air duct 120, the air in the front-section air duct 110 also partially flows to the rear-section air duct 120 after entering the accommodating cavity through the air hole 111, so that the heat of the driving unit is taken away, and the heat dissipation effect is achieved.

On the basis, the electric hair clipper also comprises a filter screen for preventing the hair from entering the accommodating cavity, so that the broken hair is prevented from influencing the service life of the driving unit; the screen is located in the air hole 111.

The present application provides an electric hair clipper further comprising a transmission unit having a reduction gear set; the shaver is in power connection with the drive unit via the transmission unit. The shaver 200 cuts hairs through reciprocating motion, and a reduction gear set is arranged between the driving unit and the shaver 200 to increase transmission torque, so that the movement of the shaver 200 is ensured to be smooth, and the phenomenon that the shaver 200 is blocked due to over dense hairs is avoided.

On the basis of the above, as shown in fig. 1 and 2, the driving unit includes a first motor 130; the first motor 130 includes a motor housing and an output shaft; one end of the output shaft extends out of the motor casing and is connected with the shaver 200 through the transmission unit in a power mode, and the other end of the output shaft extends out of the motor casing and is connected with the fan 140 in a torque-transferring mode. The use of a single motor to simultaneously drive the shaver 200 and the fan 140 can effectively reduce costs. To ensure that a good suction of the cut pieces is maintained after the trimming operation is completed, the power supply to the driving unit may be continued for a suitable time (e.g., 2 seconds or 3 seconds) after the user presses the power-off key to ensure that the fan 140 sucks the last cut piece.

In another embodiment, the driving unit includes a second motor 131 and a third motor 132; the second motor 131 drives the shaver 200 to reciprocate through the transmission unit; the third motor 132 drives the fan 140 to rotate. The use of two motors to drive the shaver 200 and the fan 140 separately makes the shaver 200 and the fan 140 separately controllable, avoids the problem that the remaining hair is not sucked well when the shaver 200 and the fan 140 are stopped simultaneously, and can be matched with different types of motors according to the powers of the shaver 200 and the fan 140.

The present application provides an electric hair clipper further comprising a power supply unit for supplying power to the drive unit; the power supply unit is a battery or an alternating current power supply which can be repeatedly charged and discharged.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
