Abstract
The utility model provides an electric drill which comprises a body and a pipe body. The body comprises a handle, a battery is mounted at one end of the handle, a motor driving a drill bit is arranged in the body, the motor comprises an output shaft, the pipe body is filled with cooling water, surrounds the motor and forms a closed loop in the body, a magnetic transmission wheel is arranged inside a position, close to the output shaft, of the pipe body, and a permanent magnet is fixedly arranged on one side, close to the magnetic transmission wheel, of the output shaft. Heat generated by the battery can be timely absorbed by the cooling water surrounding in the pipe body on the surface of the battery, and the cooling water in the pipe body is driven to circulate by the magnetic transmission wheel arranged in the pipe body by means of noncontact transmission, so that heat absorbing efficiency is high, heat absorbing effect is good, and the service life of the battery of the electric drill is greatly prolonged.
Description
Technical field
The utility model relates to field of power tools, relates in particular to a kind of electric drill.
Background technology
Electric hand drill refers to utilize electricity to do the drilling machine of power.Being the conventional products in electric tool, is also the electric tool series products that has the call.
Electric hand drill power source is internally distinguished and to be mainly contained the charging electric hand drill and rope electric hand drill two classes are arranged, and providing electric power to be called to the electric drill of electric drill motor internal by the external cable line has the rope electric drill.Usually this class electric drill adopts alternating current motor, and build is larger, powerful, sustainable working long hours.But the specification of power line and plug can be to some extent in country variant and area difference, and operating flexibility can be subject to the impact of power line length and power supply position.
The battery that is equipped with by instrument self provides the electric drill of electric power to be called wireless electric drill, and common wireless electric drill adopts d.c. motor, and build is less, and power is limited, and the sustainable working time is decided by battery capacity.Owing to there is no power line, the flexibility of operation can not be subject to the impact of power line length and power supply position.
Usually in the continuous use procedure of wireless electric drill, battery can produce a large amount of heats, if the untimely elimination of heat that battery produces, the seriously service life of battery.Therefore wireless electric drill can be offered passage on the housing of the corresponding battery setting position of drill body (operated by rotary motion is at the handle afterbody), discharges by passage the heat that battery produces.But this way, radiating efficiency is low, DeGrain.Therefore be necessary to improve.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of electric drill, can in time dispel the heat to the electric drill battery, and radiating efficiency is high, and successful.
The utility model is achieved by the following technical solution: a kind of electric drill, comprise body, described body comprises handle, an end at described handle is equipped with battery, has the motor that drives drill bit in described body, described motor comprises output shaft, also comprise body, be full of cooling water in described body, described body forms the closed-loop path around motor and in described body, the close described position of output axle of body inside is provided with the magnetic drives wheel, and described output shaft is fixedly installed permanent magnet near a side of described magnetic drives wheel.
In technique scheme, be provided with in described body for the storage tank that stores cooling water, described storage tank and described body are communicated with.
In technique scheme, be provided with through hole on described storage tank, twist on described through hole and be provided with stubborn cap.
The utility model compared with prior art, have following beneficial effect: the cooling water that the heat that the electric drill battery produces can in time be centered around in the battery surface body absorbs, and the magnetic drives wheel rotation that has in body by the transmission of the noncontact kind of drive drives cooling water circuit in body, absorb heat efficient high, effective, greatly extended service life of electric drill battery.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1, a kind of electric drill, comprise body 1, described body 1 comprises handle 3, an end at described handle 3 is equipped with battery 2, have the motor 5 that drives drill bit in described body 1, described motor 5 comprises output shaft 50.
Also comprise body 8, be full of cooling water in described body 8, described body 8 forms the closed-loop path around motor 5 and in described body 1, body 8 is provided with magnetic drives wheel 4 near described output shaft 50 inside, position, described output shaft 50 is fixedly installed permanent magnet 7 near a side of described magnetic drives wheel 4, when electric drill uses, motor output shaft 50 rotates the rotation that drives permanent magnet 7, drive the rotation of magnetic drives wheel 4 by the mode of magnetic transmission, thereby make the cooling water in body 8 to circulate.
Be provided with in described body 1 for the storage tank 6 that stores cooling water, in described storage tank 6, more cooling water is set, described storage tank 6 and described body 8 are communicated with, so just can have enough cooling waters and absorb the heat that battery produces in the electric drill running, guarantee that the cooling water heat absorption is too much ineffective after the electric drill long-play.
Be provided with through hole 60 on described storage tank 6, body 1 can be dismantled corresponding to the housing of through hole 60 positions, twist to be provided with on described through hole 60 and twist cap 61, in the long-time use procedure of electric drill, if need to increase or change cooling water in body 8, only need dismounting body 1 corresponding to the housing of through hole 60 positions, turn on cap 61, add or pour out cooling water to get final product in through hole 60.
