Description
Technical field
The utility model relates to hand warmer fields, and in particular to a kind of cold, hot two-purpose hand warmer.
Technical background
Hand warmer feature small and exquisite with its, practical, is liked by more and more people, plays in cold winter
Increasingly important role.Existing hand warmer in the market, can only warming function, hot summer or encounter need it is cold
When deposited situation, but lack practicability.
Summary of the invention
To solve the above problems, the utility model provides a kind of cold, hot two-purpose hand warmer.
The technical scheme adopted by the utility model is that: the utility model, a kind of cold, hot two-purpose hand warmer, including shell, phase
Change material layer, thermally conductive inner wall closely connect from outside to inside；Heating system/cold component includes inner radiator, semiconductor chilling plate, outer dissipates
Hot device, blower are successively electrically connected from inside to outside；Heating/refrigerating component surrounding is inlayed around an adiabatic insulation, adiabatic insulation
Between shell and thermally conductive inner wall, one end cold draining or leakage heat of the semiconductor chilling plate far from thermally conductive interior pars intramuralis are prevented；Shell
There is control circuit board in inside, is electrically connected with shell exterior power switch, power switch control hand warmer whether work and freeze or
Heating, and then circuit board controls semiconductor chilling plate current direction；The semiconductor chilling plate, radiator and blower respectively with control
Circuit board electrical connection processed；The shell is provided with air inlet in blower corresponding position；The shell is plastic material；The semiconductor
It is coated with heat-conducting silicone grease between cooling piece and radiator, fixes between three by tightening screw；The radiator is fin.
The utility model compared with existing product, there is following advantage:
(1) the drawbacks of compensating for the single heating of existing hand warmer can also provide cold while providing heat in winter
Amount drops heat and wound cold compress to summer.(2) energy is stored using phase-change material, hand warmer single charge can be effectively improved
The use time afterwards.
Detailed description of the invention
Fig. 1 is a kind of cold, hot two-purpose hand warmer structure figure.
It is as shown in the figure: 1- shell, 2- phase-change material layers, the thermally conductive inner wall of 3-, 4- semiconductor chilling plate, 5- inner radiator, 6-

Specific embodiment
A kind of cold, hot two-purpose hand warmer, including shell -1, phase-change material layers -2, thermally conductive inner wall -3 closely connect from outside to inside
It connects, cooling capacity/heat storage of generation to phase-change material layers -2 is efficiently used energy by thermally conductive inner wall -3, extends hand warmer single
The time is used after charging.
Heating system/cold component include inner radiator -5, semiconductor chilling plate -4, outer radiator -6, blower -7 from inside to outside
Successively it is electrically connected；Heating/refrigerating component surrounding is embedded in shell -1 and leads around adiabatic insulation -10, adiabatic insulation -10
Between hot inner wall -3, prevent semiconductor chilling plate -4 far from one end cold draining or leakage heat of thermally conductive -3 inside of inner wall；In shell -1
There is control circuit board -8 in portion, is electrically connected with -1 external power switch of shell, and power switch -9 controls whether hand warmer works and make
Cold or heating, and then circuit board -8 controls -4 current direction of semiconductor chilling plate.
Semiconductor chilling plate -4, radiator and blower -7 are electrically connected with control circuit board -8 respectively；Shell -1 is in blower -7
Corresponding position is provided with air inlet -12, guarantees exchanging with outside energy for the semiconductor chilling plate side far from thermally conductive inner wall one end.
Shell -1 is plastic material；Heat-conducting silicone grease is coated between the semiconductor chilling plate -4 and radiator, between three
It is fixed by screw is tightened.
The radiator is fin；The hand warmer charges by power outlet.
