Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:
Referring to Fig. 1, be the apparatus structure synoptic diagram of the replaceable spices that is used for notebook computer of the utility model one embodiment.As shown in Figure 1, the device that is used for the replaceable spices of notebook computer of the present utility model comprises: a housing 1, this housing 1 comprise a upturning lid 11 and a side socket 12, and this upturning lid 11 is articulated in housing one side; One metal heater plate 2 is positioned at the bottom that housing 1 inboard is lower than side socket 12 positions; One temperature control circuit 3 is built in housing 1, and electrically connects with metal heater plate 2; One power interface 4 is located at housing 1 side, is connected with the pc card slot (not shown) of notebook computer.
Described power interface 4 is from the pc card slot power taking of notebook computer, for described temperature control circuit 3 provides power supply, the temperature of the described metal heater plate 2 of described temperature control circuit 3 controls, the spices that makes metal heater plate 2 tops place volatilizees fast, reaches the effect of pure and fresh environment.Wherein, spices can be solid spice sheet or by the gas penetration potential liquid spice solution of plastic film wrapped preferably, the spices sheet can be opened upturning lid 11 from housing 1 top and be put on the metal heater plate 2, and also socket 12 inserts from the side; Liquid spice solution then is put on the metal heater plate 2 from housing 1 top.
The pc card slot that present most of notebook computer uses all is the slot that meets the canonical sized definition of PC CARD TYPE II, the device that is used for the replaceable spices of notebook computer of the present utility model also is the dimension definitions that meets PC CARD TYPE II standard.Therefore, the device that is used for the replaceable spices of notebook computer of the present utility model is applicable to any type notebook computer that meets PC CARD TYPE II standard.Because in the notebook computer some slots on the shelf are arranged, the utility model can utilize these slots, and this device is plugged in the notebook computer, as an accessory of notebook computer, can provide the working environment of a fresh and comfortable for the user.
Referring to Fig. 2, be the temperature control circuit synoptic diagram of another embodiment of the utility model.The temperature control circuit 3 that the utility model is used for the device of the replaceable spices of notebook computer comprises: fusible link S, a thermistor R, the first triode Q1, second a triode Q2 and a diode D1; Described fusible link S and described thermistor R electrically connect; The base stage of the described thermistor R and the first triode Q1 electrically connects; The collector of the positive pole of described diode D1 and the second triode Q2 electrically connects, and negative pole and described metal heater plate 2 electrically connect, and the collector of the described metal heater plate 2 and the first triode Q1 electrically connects; The emitter-base bandgap grading of the described first triode Q1, the second triode Q2 electrically connects.
Because the device of the replaceable spices of the utility model is used for notebook computer inside, its heating-up temperature should be not too high.Therefore, utilize this temperature control circuit 3 temperature can be controlled in certain scope.
Specifically describe the principle of work of temperature control circuit 3 below in conjunction with Fig. 1 and Fig. 2.When power interface 4 when the pc card slot of notebook computer is obtained positive 5V power supply, the temperature control circuit 3 of this device gets electric operate as normal, after 1 step-down of the positive 5V process of supply voltage resistance R, voltage when making the voltage of thermistor R be normal working temperature, at this moment, the voltage drop at thermistor R two ends is higher than the emitter voltage of the first triode Q1, therefore, the first triode Q1 is in conducting state, because resistance R 2, R3 is a fixed value resistance, so the base voltage of the second triode Q2 is fixed, and then collector voltage V2 is a definite value and less than 5V, when the first triode Q1 is in conducting, voltage V2 makes diode D1 be in conducting state greater than voltage V1, and then gives metal heater plate 2 heating; Rising along with heating-up temperature, the resistance of thermistor R can reduce, and its both end voltage also reduces thereupon, when the temperature of this device surpasses design temperature, the voltage at thermistor R two ends will be less than the first triode Q1 emitter voltage, the first triode Q1 is in cut-off state, and at this moment, voltage V1 is 5V, and the voltage of V2 is less than 5V, so voltage V1 greater than voltage V2, makes diode D1 be in cut-off state, and then stop heating to metal heater plate 2; In the time of in temperature is reduced to design temperature, the voltage at thermistor R two ends is higher than the emitter voltage of the first triode Q1 again, the first triode Q1 conducting, and voltage V1 is greater than voltage V2, and diode D1 conducting continues metal heater plate 2 heating.These temperature control circuit 3 round-robin work like this can reach the purpose of working temperature of the whole device of control.
Wherein, when the electric current that comes from laptop electric power surpassed temperature control circuit 3 running currents, fusible link S can disconnect temperature control circuit 3 and power supply 4 automatically, and protection temperature control circuit 3 is in safe work state.
Utilize the device that is used for the replaceable spices of notebook computer of the present utility model, the notebook computer operator can be according to the difference of personal preference or environment for use, at any time change different spices, such as, before soon having a rest, lavender spices sheet is put on the metal heater plate of this device,, reaches effect with fixed attention along with fragrance emanation; During operation, can put into lotus flower spices sheet, reach the effect of restoring consciouness; When overtime work, can put into essential wind oil, reach the effect of refreshing oneself.
Though the utility model with preferred embodiment openly as above; but be not in order to limit the utility model; any person skilled in the art; in not breaking away from spirit and scope of the present utility model; all can do various changes and modification, therefore protection domain of the present utility model should be with being as the criterion that claim was defined.
