DETAILED DESCRIPTION

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the following.

[0025] Reference Figure 1-4 As shown, the utility model provides a rechargeable electric hair clipper, which solves the problem of inconvenience in heat dissipation and temperature reduction treatment of the cutter head raised in the above-mentioned background technology.

[0026] To achieve the above-mentioned purpose, a rechargeable electric hair clipper includes a main body shell 1, a battery 2 is fixedly installed in the main body shell 1, a heat dissipation mechanism is provided in the main body shell 1 and on one side of the battery 2, and a clipping mechanism is provided at one end of the main body shell 1, wherein the battery 2 can supply power to the electrical components in the device to ensure the battery life, and a control switch is provided on one side of the top of the main body shell 1;

[0027] An exhaust shell 3 connected to the main shell 1 is fixedly installed on the top, and a plurality of heat dissipation fins 4 are fixedly installed on the inner bottom wall of the exhaust shell 3, and the top ends of the heat dissipation fins 4 extend out of the interior of the exhaust shell 3;

[0028] A rotating shaft rod 5 is rotatably connected between the inner walls of the exhaust shell 3, and a plurality of rotating blades 6 are fixedly installed on the surfaces of both ends of the rotating shaft rod 5, and a bevel gear 7 is fixedly installed on the middle surface of the rotating shaft rod 5;

[0029] A fixing rod 8 is rotatably connected to one side of the rotating shaft rod 5 in the exhaust housing 3 through a bracket. One end of the fixing rod 8 is fixedly connected to a bevel gear 2 9 meshing with a bevel gear 1 7 , and the other end of the fixing rod 8 is fixedly connected to a cooling fan 10 .

[0030] The utility model provides a rechargeable electric hair clipper. When in use, the hair can be trimmed through the hair clipping mechanism. At the same time, the heat released by the internal parts of the main shell 1 can be input into the exhaust shell 3 through the heat dissipation mechanism, and contact with the heat dissipation fins 4 for heat exchange. The heat dissipation fins 4 absorb the heat and transfer it to the outside for cooling. The cooled wind blows the rotating blades 6 to drive the rotating shaft rod 5 and the bevel gear 1 7 to rotate. At the same time, the bevel gear 2 9 and the fixed rod 8 that are meshed with the bevel gear 1 7 are linked to rotate, thereby driving the heat dissipation fan 10 to rotate, and the cooled wind is quickly discharged from the exhaust shell 3 to blow onto the cutter head. Therefore, the heat dissipation of the internal parts of the main shell 1 can be achieved, and the discharged wind can also be used to dissipate heat and cool the cutter head, thereby avoiding the discomfort caused to consumers by friction and heating of the cutter head, and effectively improving the use effect and the hairdressing comfort of consumers.

[0031] Furthermore, the clipper mechanism includes a clipper head 12 arranged at one end of the main body shell 1 and a motor 11 fixedly installed in the main body shell 1 and used to drive the clipper head 12 to move, wherein the structure of the motor driving the clipper head is the prior art in this field, and the specific structure and principle will not be described in detail here.

[0032] Specifically, the motor 11 can drive the clipper head 12 to move back and forth, so as to trim the hair.

[0033] Furthermore, the heat dissipation mechanism includes a motor 2 13 fixedly installed in the main housing 1 and located between the battery 2 and the motor 1 11 , and a heat dissipation fan 2 14 fixedly connected to the output end of the motor 2 13 , and the heat dissipation fan 2 14 corresponds to the exhaust shell 3 .

[0034] Specifically, when dissipating heat, the motor 2 13 drives the cooling fan 2 14 to rotate, so as to facilitate the heat inside the main shell 1 to be transported upward to the exhaust shell 3 for discharge, thereby achieving the effect of dissipating heat inside the main shell 1 and preventing its internal parts from generating a large amount of heat energy during operation that affects use.

[0035] Furthermore, a plurality of air inlets 15 are provided at the bottom of the main shell 1 , and filters 16 corresponding to the air inlets 15 are fixedly mounted on the inner bottom wall of the main shell 1 .

[0036] Specifically, through the air inlet 15, when the heat is dissipated inside the main shell 1, the cooler air from the outside can enter the main shell 1 from the air inlet 15 to achieve the effect of air circulation, so as to better dissipate heat. At the same time, dust and impurities can be filtered through the filter 16 to prevent them from entering the main shell 1.

[0037] Furthermore, a dustproof net 17 is provided at one end of the exhaust shell 3, and the dustproof net 17 is connected to the exhaust shell 3 by screws.

[0038] Specifically, by providing the dustproof net 17, external impurities and dust can be blocked and filtered to prevent dust and impurities from entering the main housing 1 through the exhaust shell 3 and affecting the use effect of its internal parts.

[0039] Furthermore, a through groove is provided at the other end of the main shell 1, in which a charging port 18 electrically connected to the battery 2 is provided, and a baffle plate 19 is hingedly connected at one end of the main shell 1 and above the charging port 18, and a connecting component is provided between the baffle plate 19 and the main shell 1.

[0040] The connecting component is composed of two iron sheets 20 symmetrically fixedly mounted on one side of the shielding plate 19 and a magnet block 21 fixedly mounted on one end surface of the main housing 1 and magnetically connected to the iron sheets 20 .

[0041] Specifically, when charging, the shielding plate 19 is rotated upward, the magnet block 21 and the iron sheet 20 are separated, so that the charging port 18 is exposed for charging. When not charging, the charging port 18 is blocked by rotating the shielding plate 19 downward, and the iron sheet 20 and the magnet block 21 are connected and fixed to the shielding plate 19, so as to shield the charging port 18 and prevent dust and impurities from clogging the charging port 18.

[0042] Working principle: When in use, the hair can be trimmed through the clipper mechanism, and at the same time, the heat released by the internal parts of the main shell 1 can be input into the exhaust shell 3 through the heat dissipation mechanism, and contact with the heat dissipation fins 4 for heat exchange cooling, and then the rotating blades 6 are blown to drive the rotating shaft rod 5 and the bevel gear 7 to rotate, and at the same time, the bevel gear 2 9 and the fixed rod 8 engaged with the bevel gear 7 are rotated through the linkage, thereby driving the heat dissipation fan 10 to rotate, and the cooled wind is quickly discharged from the exhaust shell 3 and blown onto the cutter head. Therefore, the heat dissipation of the internal parts of the main shell 1 can be achieved, and the effect of heat dissipation and cooling of the cutter head can be achieved by using the discharged wind.

Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
