Abstract
The invention provides an electric drill which comprises a body. The body comprises a handle. A battery is disposed at one end of the handle. A motor driving a bit is disposed in the body. The motor comprises an output shaft and a tube filled with cooling water. The tube encloses the motor and forms a closed loop in the body. A magnetic driving wheel is disposed inside the part of the tube, close to the output shaft. A permanent magnet is fixed one side of the output shaft, close to the magnetic driving wheel. Heat generated by a battery of the electric drill can be absorbed quickly by the cooling water around the surface tube of the battery. A magnetic driving wheel driven by means of noncontact driving in the tube drives the cooling water in the tube to circulate, so that heat absorption is efficient and effective and the service life of the battery of the electric drill is prolonged greatly.
Description
Technical field
The present invention relates to field of power tools, relate 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 the electric tool, also is the electric tool series products that has the call.
Electric hand drill internally power source is 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 is in country variant and to some extent difference of area, 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 not 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 at the housing of the corresponding battery setting position of drill body (operated by rotary motion is at the handle afterbody), discharges the heat that battery produces by passage.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 invention provides a kind of electric drill, can in time dispel the heat to the electric drill battery, and radiating efficiency is high successful.
The present invention is achieved through the following technical solutions: a kind of electric drill, comprise body, described body comprises handle, end at described handle is equipped with battery, in described body, has the motor that drives drill bit, described motor comprises output shaft, also comprise body, in described body, be full of cooling water, described body is around motor and form the closed-loop path in described body, body is provided with the magnetic drives wheel near described position of output axle inside, and described output shaft is fixedly installed permanent magnet near a side of described magnetic drives wheel.
In the technique scheme, be provided with in the described body for the storage tank that stores cooling water, described storage tank and described body are communicated with.
In the technique scheme, be provided with through hole at described storage tank, twist at described through hole and be provided with stubborn cap.
The present invention 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 having magnetic drives wheel by the transmission of the noncontact kind of drive in body rotates to drive and cools off water circuit in the body, absorbing heat efficient is high, effective, greatly prolonged service life of electric drill battery.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail: referring to Fig. 1, a kind of electric drill, comprise body 1, described body 1 comprises handle 3, 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, in described body 8, be full of cooling water, described body 8 is around motor 5 and form the closed-loop path in described body 1, body 8 is provided with magnetic drives wheel 4 near inside, described output shaft 50 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, mode by the magnetic transmission drives the rotation of magnetic drives wheel 4, thereby so that the cooling waters in the body 8 can circulate.
Be provided with in the 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 behind the electric drill long-play.
Be provided with through hole 60 at described storage tank 6, body 1 can be dismantled corresponding to the housing of through hole 60 positions, twist cap 61 described through hole 60 stubborn being provided with, in the long-time use procedure of electric drill, if need in body 8, increase or change cooling water, only needs dismounting body 1 is turned on cap 61 corresponding to the housing of through hole 60 positions, adds or pour out cooling water to get final product in through hole 60.
