Description
Technical field
The utility model relates to a kind of handpiece structure of Sewing machines, is specifically related to a kind of head radiator structure of the all-in-one of sewing.
Background technology
Electric sewing machine is the main flow of existing industry or civilian Sewing machines, and owing to having applied motor and electric control gear, its relevant power component is all large thermal source, so heat radiation just becomes a very important task.
The main heat radiation position of existing electric sewing machine and radiating mode roughly comprise following several:
The firstth, head, employing be natural heat dissipation or fan cooling.
The secondth, servo controller, the radiator of the power component of servo controller interior circuit board is natural heat dissipation or employing fan cooling in air directly.
The 3rd is motor, employing be that the blast fan of natural heat dissipation or handwheel dries to dispel the heat.
In radiating mode for above each position, prior art does not consider and makes overall plans comprehensively, to adopt the lower natural heat dissipation mode of efficiency, to increase fan or utilize handwheel blast fan to carry out wind-cooling heat dissipating to a certain parts wherein, cooling effectiveness is low, also will increase energy consumption and increase volume; Moreover be the key position that prior art fails to be absorbed in heating, share out equally cooling air quantity, specific aim is poor.
Through retrieval, find, application number is 201310408056.6, name is called " a kind of sewing machine header structure that is provided with interior heat abstractor ", disclose a kind of sewing machine header structure that is provided with interior heat abstractor and comprised the cover cap that is arranged on head right part, the inside of cover cap is fixed with motor and servo controller, it is characterized in that, a columniform cavity is arranged at the top of cover cap, and motor is positioned at the centre of cavity, servo controller is fixedly connected on the bottom of cover cap, servo controller is provided with the interior heat abstractor of an arc-shaped structure, interior heat abstractor covers at deep gouge oral area and is fixed on cavity wall, the lateral surface of interior heat abstractor arc-shaped structure is directly connected with the power component of circuit board in servo controller, the medial surface of interior heat abstractor arc-shaped structure towards motor and and motor retain certain distance with cooling gas circuit together with formation, the rear shaft end of motor is connected with handwheel, the interior survey of handwheel is provided with blast fan, the right side of blast fan is furnished with dust cover, dust cover is connected to cover cap right part, dust cover is provided with air admission hole, there is cooling air channel in blast fan the place ahead, the composition of cooling air channel comprises the gap of described cavity and motor, cooling gas circuit between the outer surface of servo controller and interior heat abstractor and motor, and head of sewing machine inner chamber.This application arranges cooling gas circuit together and to motor and interior heat abstractor, dispels the heat simultaneously in head of sewing machine, owing to only having single air channel, the holdup time of cooling blast in head is short, heat radiation is slow, and motor surface is different with the windage on interior heat abstractor surface, easily causes the cooling blast of local process even without cooling blast, to pass through less.
Utility model content
The purpose of this utility model is that the local radiating effect that the Sewing machines list cooling airway radiator structure of prior art exists is poor, and the inefficient problem of integral heat sink proposes a kind of head radiator structure of sewing all-in-one of dual cooling air flues.
