Abstract
A mercury-free non-electronic type thermometer with a support structure comprises the support structure, a heat conducting layer, a temperature scale layer and a temperature sensing color-changing layer, wherein the heat conducting layer is located on the outer layer of the support structure and comprises a heat sensing portion and a temperature displaying portion, the temperature scale layer is marked on the surface of the temperature displaying portion or at the position above the temperature displaying part, and the temperature sensing color-changing layer is at least formed on the temperature displaying portion to cover the temperature scale layer. The heat sensing portion on the support structure senses the heat contact face of a user to conduct heat conducting flow to the temperature sensing color-changing layer at the temperature displaying portion, and the temperature sensing color-changing layer generates a color-changing area according to the temperature the heat flow corresponds to so as to expose a corresponding temperature scale value. The mercury-free non-electronic type thermometer with the support structure does not contain mercury so as to avoid toxic pollution, and simultaneously greatly reduces cost in comparison with an electronic thermometer. In addition, the mercury-free non-electronic type thermometer with the support structure does not need to be provided with a chemical battery so as to be capable of avoiding causing insufficient power during use due to the fact that the thermometer causes loss of the chemical battery caused by long time no use while avoiding polluting the environment.

The specific embodiment
Please be simultaneously referring to figs. 1 to Fig. 4, it shows an embodiment of clinical thermometer of the present invention.At first as shown in Figure 3, clinical thermometer 50 comprises supporting structure 40, and generally speaking, supporting structure 40 can be to be made up of metal body or plastic body.And in one embodiment, for alleviating thermal capacity, supporting structure 40 forms with the hollow body mode, and for making things convenient for user to measure body temperature and avoiding injury, the leading section surface of supporting structure 40 can be the smooth curve shape, and can be made up of a soft material in addition.
Secondly, see also Fig. 1 and Fig. 4, heat-conducting layer 10 is positioned at the outer surface of supporting structure 40, and it comprises a 10b of sensible heat portion and a temperature display part 10a.In one embodiment, the 10b of sensible heat portion is in abutting connection with the leading section of supporting structure 40.Temperature scale layer 20 for example uses waterproof ink, and each temperature value of mint-mark is in temperature display part 10a surface or its top position of heat-conducting layer 10.
In supporting structure 40 is among the embodiment of hollow metal pipe, and the outer surface of hollow metal pipe can be directly as heat-conducting layer 10.And be among the embodiment of hollow plastic pipe in supporting structure 40, can coat in addition one deck sensible heat film or heat sensitive paper on the outer surface of hollow plastic pipe with as heat-conducting layer 10, generally speaking, sensible heat film or heat sensitive paper comprise the metal material of high-termal conductivity.
See also Fig. 2 and Fig. 4, heat discoloration layer 30 is formed on the temperature display part 10a of heat-conducting layer 10 at least.The thermal interface of the 10b of the sensible heat portion sensing user on the supporting structure 40 wherein is with the heat discoloration layer 30 on conductive heat flow to the temperature display part 10a.As shown in Figure 5; Heat discoloration layer 30 can produce a transformation region 30X according to the corresponding temperature of hot-fluid; Go up corresponding temperature scale to expose temperature display part 10a; Therefore the remainder of heat discoloration layer 30 not transformation region 30Y still keeps primitive color then because of temperature does not reach not variable color of marginal value.
Wherein, among the embodiment as shown in Figure 2, the lower temperature scale value (heat discoloration block 30a) that can select to go up the temperature scale layer with temperature display part 10a is adjacent to the 10b of sensible heat portion, and with higher temperature scale value (heat discoloration block 30n) away from the 10b of sensible heat portion.For example; Heat discoloration layer 30 can be divided into the heat discoloration block 30a～30n of a plurality of each temperature scale of correspondence; Each block is minimum critical value of discoloration with each temperature scale respectively then; Therefore when the heat discoloration layer 30 of the 10b of sensible heat portion conductive heat flow to temperature display part 10a, the corresponding temperature of hot-fluid can make minimum critical value of discoloration this below temperature each block variable color and form transformation region, for example; When recording temperature and be 37 degrees centigrade, can make critical value of discoloration change color and form transformation region 30X at each block below 37 degrees centigrade such as 30a～30c; Critical value of discoloration then remains unchanged at each block more than 37 degrees centigrade.Wherein, the primitive color of heat discoloration layer 30 can be covered temperature scale, and the color after the change of transformation region can be another kind of color or form transparent region with the displays temperature scale value.
Please consult Fig. 2 again, in one embodiment, heat discoloration layer 30 can be made up of multiple structure, has the more block of layer structure, and its critical value of discoloration is higher, and the high temperature that also promptly need heal can make it variable color.For example, can be coated with one deck heat discoloration thin film earlier in heat-conducting layer 10 surfaces, scope can contain whole temperature scale layer at least; Secondly; Coating second layer heat discoloration thin film is in heat-conducting layer 10 surfaces, but scope only contains the above zone of second temperature scale, and the rest may be inferred.Therefore, the heat discoloration thin film of minimum temperature scale block (heat discoloration block 30a) is the thinnest, and the heat discoloration thin film of maximum temperature scale block (heat discoloration block 30n) is the thickest.In addition, the multiple structure of heat discoloration layer 30 also can be selected to be made up of the thin film of multilamellar different components or doping different proportion, or select to form each independently monolayer heat discoloration piece on each block.
Comprehensively above-mentioned; Because the clinical thermometer of present embodiment does not contain hydrargyrum, therefore can avoid toxic pollution, cost significantly reduces than electronic clinical thermometer simultaneously; This clinical thermometer need not be provided with the chemical battery in addition; Except that avoiding the environmental pollution, can prevent that also clinical thermometer from need not cause the chemical battery loss because of putting for a long time, power shortage when causing using.
