Abstract

The utility model discloses a cup, belonging to the technical field of articles for daily use and comprising a cup body, wherein the cup body consists of an inner-layer cup body and an outer-layer cup body which form a closed cavity; the cavity is internally provided with a thermistor and a small bulb which are connected with a battery by leads so as to form a closed circuit. The cup is simple in structure, and can intuitively judge the temperature of water in the cup, and avoid scalding due to overhigh water temperature. In addition, the cup does not adopt a thermometer, thus being safer.

Description

Cup

Technical field

The utility model relates to a kind of cup, is specifically related to a kind of cup that can judge water temperature.

Background technology

At present, a variety of thermos cups have been arranged on the market, they can make water be incubated for a long time.But the general wall of cup thermal insulation of these water tumblers is very strong, and with the true temperature of feel feel less than water, the situation that the regular meeting's generation often of drinking water irons because do not understand water temperature, this situation is especially serious for the child.Had the people to invent the water tumbler that has thermometer, but water tumbler drop to the ground and is easy to make the thermometer fragmentation, has potential safety hazard for this situation.

Summary of the invention

The utility model provides a kind of cup that can judge water temperature in order to overcome above-mentioned deficiency, and it can allow the people judge the height of water temperature intuitively, prevents to produce because of water temperature is overheated scald.

The utility model is realized by following measure:

A kind of cup, comprise cup, described cup is made up of internal layer cup and outer cup, and inside and outside two-layer cup forms the cavity of a closure, be provided with thermistor and miniature bulb in the described cavity, described thermistor and miniature bulb are connected to form the closed-loop path by lead and battery.

Further, be fixed in internal layer cup lateral wall lower end in order to judge water temperature, thermistor more accurately, miniature bulb is fixed on the outer cup madial wall.

Further, in order significantly to see the situation of bulb, outer cup is made by rigid transparent material.In addition, described miniature bulb can be redness, so that observe.

Further, also be provided with battery case in the described cavity, described battery is positioned at battery case, can change new battery after battery uses up.

Principle of the present utility model is: thermistor reduces gradually with its resistance of rising of water temperature.When pouring hot water in cup, the thermistor resistance diminishes, and this moment, miniature bulb was bright, and hydro-thermal is described; When water temperature reduced gradually, resistance value constantly raise, thereby made miniature bulb deepening gradually, illustrated that water temperature reduces, and can drink.

Beneficial effect: the utility model is simple in structure, can judge the height of water temperature in the cup intuitively, has avoided producing because of water temperature is too high scald.In addition, the utility model does not adopt thermometer, and is safer.

Wherein, 1, outer cup, 2, the internal layer cup, 3, cavity, 4, thermistor, 5, miniature bulb, 6, lead, 7, battery, 8, battery case.

The specific embodiment

Below by the drawings and specific embodiments the utility model is further set forth.

Cup as depicted in figs. 1 and 2, comprise cup, cup is made up of internal layer cup 2 and outer cup 1, interlayer between internal layer cup 2 and the outer cup 1 forms the cavity 3 of a closure, be provided with thermistor 4 and miniature bulb 5 in the described cavity 3, thermistor 4 and miniature bulb 5 are connected to form the closed-loop path by lead 6 and battery 7.In order to judge water temperature more accurately, thermistor 4 is fixed in internal layer cup 2 lateral wall lower ends, and in order significantly to see the situation of bulb, miniature bulb 5 is red, and the outer cup 1 of cup adopts rigid transparent material to make.In addition, change battery for convenience, also be provided with battery case 8 in the cavity 3, battery 7 is positioned at battery case 8.

Above-mentioned explanation does not limit the utility model just in order to explain principle of the present utility model and advantage.
