Technical field

The utility model relates to a kind of cup, especially a kind of cup that liquid such as beverage, tea are heated and freeze of can be used for.

Background technology

Growth along with economy, the raising day by day of people's living standard, the scope of activities that people more and more are not content with oneself is confined to indoor, but turn to some outdoor activities gradually, see a film as cinema, go window-shopping, travel outdoors etc., at this moment people always wish can be at any time and drink easily heat or ice beverage, tea etc. are (especially when uncomfortable, when urgent need hot water is taken medicine), but existence conditions but can't satisfy people's this hope, conventional cup can only be used for holding tea, beverage, it is played insulation effect, but can't realize long-time heat insulation effect, more impossible beverage and tea are heated and freezed.Existing refrigeration apparatus generally mostly is refrigerator on the market, but because the refrigerator volume is big, Heavy Weight is not easy to move, carries etc., also can't satisfy people's this demand.Therefore, for now, people drink the beverage of ice easily when being difficult in torridity summer and going out, and in the time in winter, when people go out for a long time, also may be through regular meeting drink tea less than heat owing to lack this equipment.Therefore, these have increased the puzzlement in people's life invariably, and giving travels outdoors brings great inconvenience.Past also once the someone designed the less refrigerator of volume, can realize the effect that heats and freeze in theory, but general refrigerator all needs external power supply, as vehicular refrigerator or indoor mini-bar, the shortcoming of these refrigerators is that people can not be in time easily to the refrigerator power supply when going out, and this refrigerator does not have the function of heating simultaneously.Therefore, at above situation, people's life is designed a kind of cup portable and that can heat beverage or tea etc. simultaneously and freeze and is necessary for convenience, has great practical value.

Summary of the invention

The utility model is will provide a kind of can carry, can realize the portable cold, hot two-purpose cup of heating and refrigeration to beverage, tea, this cup adopts semi-conducting material to heat or freezes, utilize ptc and ntc material to realize, and use solar cell to provide energy as whole system to temperature controlling.

In order to achieve the above object, the technical solution of the utility model is; A kind of portable cold, hot two-purpose cup, comprise inner core, urceolus, be characterized in: outer drum outer wall posts solar panels, be provided with switch in the outer tube end plate, inner tank theca posts the semiconductor of heating and refrigeration, is provided with battery case and circuit board below the interior tube end plate, battery case is built-in with the solar cell that is connected with solar panels or external power source, and the refrigeration in the circuit board, heater circuit are connected with battery case with semiconductor.

Refrigeration, heater circuit are serially connected with the PTC resistance and the NTC resistance of the temperature that is used to control heating and freezes, and wherein PTC resistance is attempted by in the circuit of solar cell and switch composition respectively with after semiconductor is connected with NTC resistance.

Switch is the SP3T switch, and three gears are respectively to freeze, heat and close gear.

The beneficial effects of the utility model are: owing to adopted semi-conducting material, therefore need not to add other refrigeration and heating material, shell adopts plastic material simultaneously, utilizes solar cell for supplying power, need not to change battery.Therefore, it is little, in light weight to the utlity model has volume, the convenient use, and characteristics such as be easy to carry.

The design of the utility model volume is less and conventional cup is similar, for high 28 centimetres, and the cylinder that radius is 7 centimetres, weight only has 0.5kg.Because volume is little, in light weight, therefore conveniently carry.The utility model adopts semi-conducting material to freeze and heat, advantages such as that semi-conducting material has is shockproof, noiselessness, the life-span is long, temperature range is wide, and can not produce pollution to environment, satisfy people to environmental protection requirement.The semiconductor position is placed in the cavity between the inner/outer tube, adopt the placement form that directly is attached to inner tank theca, and temperature conduction is very fast.Aspect energy supply, the utility model has used solar cell, the built-in high-capacity lithium-ion of this battery, thereby make equipment not only can use external power charging, can also use outside solar panel that it is charged, solar panel is placed on the outside of cup, can come harvest energy by gathering sunlight, with satisfy electric weight when not enough cup to the demand of electric energy.On the overall structure, the inner core material use be easy to conduct heat and quality lighter metallic material of aluminum, outsidely use the light plastic material, thereby reach attractive in appearance, economical and practical effect.

In order to realize the adjusting of tea or the cold and hot effect of beverage, the utility model has related to gauge tap, and this switch has three gears, a control refrigeration, a control heating, the 3rd on off state that is used for controlling whole system.Therefore, people can carry out the adjusting of switch according to the needs of oneself.In order to realize to refrigeration and heat temperature controlling in the process that we have adopted ptc thermistor and ntc thermistor material, in the heating process, when temperature reaches certain numerical value, the ptc material plays a role, and makes the temperature of heating can't continue to rise, thereby can not burn out semiconductor; In the process of refrigerastion, when temperature dropped to certain numerical value, the ntc material played a role, and the temperature of refrigeration can't be descended, and ptc and ntc material weight are lighter, and volume is less, the convenient use.

The specific embodiment

Below in conjunction with accompanying drawing and example the utility model is further specified.

As Fig. 1, shown in 2, portable cold, hot two-purpose cup of the present utility model comprises solar panels 1, circuit board 2, switch 3, battery case 4, urceolus 5, inner core 6, the semiconductor 7 of heating and refrigeration, negative temperature coefficient heat-sensitive (NTC) resistance 8, positive temperature coefficient temperature-sensitive (PTC) resistance 9.

Urceolus 5 outer walls post solar panels 1, be provided with switch 3 in urceolus 5 base plates, inner core 6 outer walls post the semiconductor 7 of heating and refrigeration, be provided with battery case 4 and circuit board 2 below inner core 6 base plates, battery case 4 is built-in with the solar cell that is connected with solar panels 1 or external power source, and the refrigeration in the circuit board 2, heater circuit are connected with battery case 4 with semiconductor 7.

Power supply is a solar cell, can directly charge, and also can charge by gathering solar energy.Use semi-conducting material in refrigeration and the heating system, in order to prevent the transition heating or excessively freeze that connected PTC resistance 9 and NTC resistance are controlled the temperature of heating and refrigeration in circuit.Switch 3 adopts SP3T switch, three effects that gear is realized respectively freezing, heating and close.Because equipment volume is less, in light weight, is convenient to the user and carries.

Inner core 6 outer walls post heating and the refrigeration of semi-conducting material realization to object, and inner core 6 adopts metal materials to make, and material is light, and temperature conduction is effective.

Used PCT and NTC material in the semi-conductive heating and cooling circuit, can realize stable control, used the selection of SP3T switch realization simultaneously refrigeration, heating and power switch to temperature.

Adopt solar cell in the battery case 4, not only can use external power source to charge, can also be by using solar panel, collection luminous energy is converted into the mode of electrical power storage in battery case and comes to power devices, solar panel 1 sticks on cup outer wall place, convenient collection to solar energy.
