Abstract
The utility model relates to an electric tool technical field especially relates to an electric circular saw, including the casing and be located motor (3) and controller (4) of casing, motor (3) are connected with controller (4) electricity, be equipped with air intake (7) on the casing, controller (4) set up on being close to the casing of air intake (7). This kind of electric circular saw controller radiating effect is better.
Description
Technical field
This utility model relates to electric tool technical field, particularly relates to a kind of electrotrephine.
Background technology
Electrotrephine is a kind of instrument driving saw blade to carry out sawing action for power by drive mechanism with motor.Prior art electrotrephine mainly includes casing, the motor being arranged in casing and for controlling the controller of motor, but the location of controls being because prior art arranges unreasonable, not on the air channel of electrotrephine, so causing the radiating effect of controller poor, and then cause service life of whole electrotrephine relatively low.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of preferable electrotrephine of controller radiating effect.
This utility model be the technical scheme is that a kind of electrotrephine, and the motor including casing and being positioned at casing and controller, described motor is electrically connected with the controller, and described casing is provided with air inlet, and described controller is positioned close in the casing of air inlet.
Use above structure compared with prior art, this utility model has the advantage that and is positioned close in the casing of air inlet by controller, the air being so blown into from the air inlet of casing will pass through controller, thus well can dispel the heat to controller, and then make service life of whole electrotrephine elongated.
As preferably, described casing is divided into right casing and left casing, and described motor is arranged in left casing, and described right casing is provided with air inlet, and described controller is arranged on left casing one end near air inlet.So arranging, be arranged on by controller near the air inlet of right casing, the radiating effect of such controller is preferable, and is fixed in left casing, and fixing also ratio is stronger.
As preferably, left casing is provided with at least two round platform near one end of air inlet, and described controller is connected on round platform.So arrange make distance between the air inlet of controller and right casing closer to, and then make the radiating effect of controller more preferable.
As preferably, described round platform is two, and two round platform circumferences are uniformly distributed.Using two round platforms just energy well static controller, such cost is relatively low, and fixed effect is preferable.
Accompanying drawing explanation
Fig. 1 is a kind of sectional view directly driving electrotrephine of this utility model.
As shown in the figure: 1, right casing；2, left casing；3, motor；4, controller；5, electrotrephine；6, output shaft；7, air inlet；8, round platform.
Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with accompanying drawing, but this utility model is not limited only to detailed description below.
As it is shown in figure 1, this utility model one electrotrephine includes right casing 1, left casing 2, motor 3, controller 4 and saw blade 5.Motor 3 is arranged in left casing 2, and saw blade 5 is arranged on outside right casing 1, and the output shaft 6 of motor 3 is directly connected with saw blade 5, and right casing 1 is provided with air inlet 7, and motor 3 electrically connects with controller 4.Left casing 2 is provided with two round platforms 8 near one end of air inlet 7, and two round platform 8 circumferences are uniformly distributed, and controller 4 is arranged on two round platforms 8.Left casing 2 is for placing the afterbody that position is left casing 2 bearing chamber of controller 4, here it also is provided with some air intake through holes for air circulation, so air enters from the air inlet 7 of right casing 1, first controller 4 is flowed through, it is flowed in left casing 2 from these air intake through holes the most again, motor 3 is dispelled the heat.
Described controller 4 is fixed by screws on round platform 8, and so fixing ratio is stronger.And controller 4 still has some distances from shell body 1 after being arranged on round platform 8, air inlet 7 leaked-in air from shell body 1 so can be allowed preferably to circulate, without being blocked completely by controller 4.
Embodiments described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
