At present, also have the wearing temperature sensor based on thermal sensitive effect, can facilitate the measurement of body temperature, Practical Performance is very strong, but existing Wearable temperature sensor, probe be all made by metal material discoid, or hemispherical; Be embedded on sensor external member or dress on parts.Discoid probe plays protection and conductive force; inside connects sensitive component (critesistor or temperature-sensitive electric capacity etc.); between the two by heat-conducting filler in succession; avoid air insulated, this kind of temperature sensing probe, conduction of heat inefficiency; only some touches probe to sensitive component; (part is present in conduction of heat space), other parts are exposed to heat leakage space after surrounding heat-conducting filler.Cause temperature-sensitive device heating surface to be less than radiating surface, thermoinduction weak effect, heat up slow, need could measure temperature for a long time, and cause the too low problem of warming efficiency, sensory experience is not good enough, there is deficiency.
In sum, for the defect of prior art, need the packaging type temperature sensor being applicable to wearable device especially, to solve the deficiencies in the prior art.
Utility model content
For the deficiency that Wearable temperature sensor heat conduction in prior art is slow, affect the experience of actual wearer, the utility model proposes the packaging type temperature sensor being applicable to wearable device, novel in design, be convenient for carrying, change original hot sensing mode, sensitive component is all surrounded by probe, and will receive the conduction of heat in whole direction, heat conduction is rapid, organoleptic properties is excellent, addresses the deficiencies of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Be applicable to the packaging type temperature sensor of wearable device, comprise the housing of sensor, one end of housing is provided with probe, probe adopts the material that heat conductivity is high, and the measuring junction of probe is cambered outwards convex structure, and the bottom of probe is provided with thermal insulation layer, the centre of probe is the tubular structure of hollow, it is inner that temperature-sensitive element is connected probe by tubular structure, and the arranged outside of temperature-sensitive element has conductive filler layer, and conductive filler layer adopts metal.
Further, heat insulating mattress is provided with between described probe and housing.
Further, described temperature-sensitive element leads to wire by tubular structure, and wire includes power line, holding wire.
Be heat insulation foam at the packing material of thermal insulation layer inside described in the utility model.
The beneficial effects of the utility model are: this product structure is simple, change original hot sensing mode, sensitive component is all surrounded by probe, to the conduction of heat in whole direction be received, more than 3 times are shortened to the Measuring Time of body temperature, improve the sensory experience of wearable device, Practical Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
This utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model.
100-housing in figure, 110-pops one's head in, 120-temperature-sensitive element, 130-conductive filler layer, 140-thermal insulation layer, 150-wire, 160-heat insulating mattress.
Detailed description of the invention
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth this utility model further.
See Fig. 1, the packaging type temperature sensor being applicable to wearable device, comprise the housing 100 of sensor, one end of housing 100 is provided with probe 110, probe 110 adopts the material that heat conductivity is high, the measuring junction of probe 110 is cambered outwards convex structure, and the bottom of probe 110 is provided with thermal insulation layer 140, and the centre of probe 110 is the tubular structure of hollow, it is inner that temperature-sensitive element 120 is connected probe 110 by tubular structure, and the arranged outside of temperature-sensitive element 120 has conductive filler layer 130.
The heat-conducting filler of conductive filler layer of the present utility model uses metal, utilizes the characteristic that some alloy melting point is low, and this point is for promoting heat conducting key point.Such as: low temperature scolding tin, its fusing point, at about 160 DEG C, lower than the fusing point of sensor outsourcing resin, pours into when being melted in probe pipe as conductive filler material.The heat conductivity of scolding tin reaches 70W/ (mK), far above the heat conductivity of existing heat conductive silica gel, silicone grease, thus significantly promotes conduction of heat usefulness.
And be provided with heat insulating mattress 160 between probe 110 and housing 100, temperature-sensitive element 120 leads to wire 150 by tubular structure, and wire 150 includes power line, holding wire, and the packing material of thermal insulation layer 140 inside is heat insulation foam.
Use procedure of the present utility model is: pop one's head in and to be made up of the material that heat conductivity is high, such as metal, probe front portion is divided into body contact part outwardly (between 0.5mm-5mm), in elliptic arc wire, to press human body skin, whole probe can both be close to skin simultaneously, avoids probe edge and skin to there is air to greatest extent.Outward appearance camber line is relevant with outstanding height, obtains by experiment correction; Different fat or thin people, radian is also inconsistent.Probe mid portion is tubulose, sensitive component will be inner by this pipe whole insertion probe, the diameter of the sensitive component that the internal diameter of pipe is as far as possible close, when headspace can cover and fill heat-conducting filler, drain inner air, but reduce the use of heat-conducting filler, therefore headspace is unnecessary too large as far as possible.Implant uses liquid metal, as low temperature scolding tin, its fusing point is at about 140 DEG C, even lower than the fusing point of ABS plastic, can be used for doing conduction of heat packing material, and the coefficient of heat conduction of scolding tin is 67, much larger than heat conductive silica gel used on the market, pipe thickness no requirement (NR), the pipe degree of depth equals thermosensitive part length, the heat-conducting filler degree of depth, the thermal insulation layer degree of depth and, probe rear portion is divided into standing part, as far as possible thin, diameter is as far as possible little, to avoid heat loss, when probe is installed, need, between sensor main body, a heat insulation external member is installed, inner covering one deck thermal insulation layer, so the non-human skin contact of probe is all wrapped in thermal insulation layer.
This temperature probe, changes original hot sensing mode, and sensitive component is all surrounded by probe, will receive the conduction of heat in whole direction.Experiment proves original sensing mode, during take temperature, is warming up to 36.5 degrees Celsius of demands about 25 minutes by 33 DEG C, and after using this probe, the heating-up time only needs about 7 minutes.
This utility model is effective is: structure is simple, change original hot sensing mode, sensitive component is all surrounded by probe, to the conduction of heat in whole direction be received, more than 3 times are shortened to the Measuring Time of body temperature, improve the sensory experience of wearable device, Practical Performance is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
