Abstract

The utility model discloses a refrigerating heater with USB plug, comprising a box and a bottom cover, a cooling fan and a control circuit board mounted in the box, a control chip in the circuit, a thermal conductive fin and a radiator respectively mounted at upper and lower sides of the control chip, and a USB plug connected with the control chip and protruded outside the box. The invention is characterized in that the control chip can control refrigerating and heating, while the box is also arranged with a switch for selecting refrigerating or heating modes, which can be connected with a computer to refrigerate or heat milk, coffee, drink and tea.

Description

Refrigeration, the heater of band USB plug

Technical field

The utility model relates to a kind of refrigeration, heater of refrigeration, heating milk, coffee, beverage and the tea etc. that can be connected with computer.

Background technology

Now had the refrigerating plant of refrigeration milk, coffee, beverage and the tea that can be connected with computer, the advantage of this device is to be connected with computer, thus very easy to use, do not need other refrigeration plant.But this device can't satisfy the crowd who likes drinking hot milk, coffee, beverage and tea.Therefore design and a kind ofly promptly can freeze, refrigeration, the heater of the band USB plug that can heat or be incubated have again become people's demand.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can be connected with computer, can freeze, again can heating milk, refrigeration, the heater of coffee, beverage and tea.

Above-mentioned purpose adopts following technical scheme just can realize: this device is the same with prior art, comprises box body and bottom, is contained in cooling fan and control circuit board in the box body, comprises a control chip in the circuit; Both sides up and down at control chip are equipped with conducting strip and radiator respectively; Also have one that be connected with control chip, stretch out USB plug in the outside of box body, its improved part is that said control chip is the chip that can control refrigeration and heating, and also is provided with one can control chip just connecing or the change-over switch of freezing or heating is promptly selected in reversal connection on box body.

The beneficial effects of the utility model are:

Only need the USB plug of this device is inserted the USB interface of computer, utilize change-over switch to select refrigeration or heating function after, just can or be incubated milk, coffee, beverage and tea cooling or heating, it is extremely convenient to use; And this apparatus structure is very simple, and is therefore cheap, is easy to promote the use of.

In order to make the utility model more clear, it is described further below by drawings and Examples.

Concrete embodiment

Embodiment 1, referring to Fig. 1-Fig. 7.Present embodiment comprises box body 2 and bottom 5, is contained in cooling fan 8 and control circuit board in the box body 2, comprises a control chip 7 in the circuit; In the both sides up and down of control chip 7 conducting strip 1 and radiator 6 are housed respectively; Also have one 7 that be connected with control chip, stretch out USB plug 3 in the outside of box body, and this control chip 7 is the chips that can control refrigeration and heat.Also being provided with simultaneously one on box body 2 can control chip just connect or the change-over switch 4 of freezing or heating is promptly selected in reversal connection.

Among Fig. 2 shown in 21 is the ventilating opening of cooling fan 8; Among Fig. 3 shown in 22 is the transom of radiator 6; USB1 promptly is above-mentioned control chip 7 among Fig. 8, and F is a cooling fan 8, and K1, K2 are change-over switches 4.

Embodiment 2, referring again to Fig. 8.The difference of present embodiment and the foregoing description only is that the said chip that can control refrigeration and heating is the chip of TEC series, and the positive terminal of this chip two lines in parallel, these two lines connect the forward contact of change-over switch K1 and the counter-contact of change-over switch K2 respectively, the negative pole end of this chip two lines in parallel, these two lines connect the forward contact of change-over switch K2 and the counter-contact of change-over switch K1 respectively; Change-over switch K1, K2 are linked switch, and wherein K1 connects the VCC end of USB plug, and K2 connects the GND end of USB plug, and the two poles of the earth of cooling fan are in parallel with the two ends of change-over switch K1, K2.So, when change-over switch 4, just can select the function of freezing or heating.

Claims

1, a kind of refrigeration with USB plug, heater comprise box body and bottom, are contained in cooling fan and control circuit board in the box body, comprise a control chip in the circuit; Both sides up and down at control chip are equipped with conducting strip and radiator respectively; Also have one that be connected with control chip, stretch out USB plug in the outside of box body, it is characterized in that said control chip is the chip that can control refrigeration and heating, and on box body, also be provided with one and can control chip just connecing or the change-over switch of freezing or heating is promptly selected in reversal connection.

2, the refrigeration of band USB plug according to claim 1, heater, it is characterized in that the said chip that can control refrigeration and heating is the chip of TEC series, and the positive terminal of this chip two lines in parallel, these two lines connect the forward contact of change-over switch K1 and the counter-contact of change-over switch K2 respectively, the negative pole end of this chip two lines in parallel, these two lines connect the forward contact of change-over switch K2 and the counter-contact of change-over switch K1 respectively; Change-over switch K1, K2 are linked switch, and wherein K1 connects the VCC end of USB plug, and K2 connects the GND end of USB plug, and the two poles of the earth of cooling fan are in parallel with the two ends of change-over switch K1, K2.
