Description
Technical field
This utility model is related to field of power tools, more particularly, to a kind of garden instrument that lithium battery pack can be lowered the temperature.
Background technology
Garden instrument mainly includes hay mover, pruner, chain saw and hair-dryer etc..
Because lithium electricity is the higher new forms of energy of a kind of environmental protection, energy density, so the garden instrument master of prior art
Lithium battery pack to be adopted is as its main power source.But the shortcoming of lithium battery pack is, when its lasting heavy-current discharge, temperature
Can drastically raise, easily explode during high temperature, thus not only garden instrument is caused with very big damage, shorten lithium battery pack and gardens
The service life of instrument, and bring potential safety hazard to user.
Utility model content
Technical problem to be solved in the utility model is：A kind of long service life is provided, safe, can be to lithium electricity
The garden instrument of Chi Bao cooling.
This utility model be employed technical scheme comprise that：A kind of garden instrument that lithium battery pack can be lowered the temperature, this gardens
Instrument include housing, lithium battery pack and be arranged on housing supply battery bag grafting plug socket, housing be provided with air inlet with
And air outlet, wherein, plug socket side is provided with a fan, and fan is located between air inlet and air outlet.
After above structure, compared with prior art, this utility model has advantages below：In the setting of plug socket side
One fan, and fan be located between air inlet and air outlet, extraneous air can be preferably drawn into slotting by such fan
To lithium battery pack radiating in joint chair, then flowing out from air outlet again, thus playing preferable radiating effect to lithium battery pack, dissipating
It is also possible to extend lithium battery pack and the service life of garden instrument while heat problem solves, improve their safety in utilization.
Preferably, one end that lithium battery pack is exposed at hull outside can set multiple fresh air inlets, it inserts in plug socket
End can set multiple exhaust vents, and exhaust vent is connected with air inlet.So extraneous air can flow through inside lithium battery pack, can be more
Good radiates to lithium battery pack, and radiating effect is more preferable.
Preferably, being provided with the cavity for housing motor in housing, air inlet is all communicated with cavity with air outlet.At present
Most of garden instruments are provided with one for the fan to motor radiating, and the air inlet at aluminum cell bag plug socket and air-out
After mouth is connected with the cavity of accommodating motor, the fan at motor position can also radiate to lithium battery pack, two fan works simultaneously
Work can further enhance the radiating effect of lithium battery pack.

Specific embodiment
With specific embodiment, this utility model is described further below in conjunction with accompanying drawing, but this utility model is not only
It is limited to detailed description below.
Fig. 1 and Fig. 2 show chain saw, is the one of which in garden instrument, this utility model is using chain saw as concrete reality
Apply example, but be not limited only to chain saw, as long as similar also possible of other garden instrument base component.
In this embodiment, garden instrument includes housing 1, lithium battery pack 3 and is arranged on and supplies battery on housing 1
Wrap the plug socket 4 of 3 grafting, housing 1 is provided with air inlet 7 and air outlet 6, plug socket 4 side is provided with a fan 8, fan 8
Between air inlet 7 and air outlet 6.Be provided with the cavity 5 for housing motor 2 in housing 1, air inlet 7 and air outlet 6 all with
Cavity 5 communicates.One end that lithium battery pack 3 is exposed at outside housing 1 is provided with multiple fresh air inlets 9, and the one end in its insertion plug socket 4 sets
There are multiple exhaust vents 10, exhaust vent 10 is connected with air inlet 7.It is provided between lithium battery pack 3 and plug socket 4 and flow through for outside air
Lithium battery pack 3 and then flow to the passage of air inlet 7.
