Embodiment
Fig. 1 is the front elevation of the two core maximum/minimum thermometers of the present invention, and Fig. 2 is its side view.
Below in conjunction with embodiment the two core maximum/minimum thermometers of the present invention are described in more detail.
The two core maximum/minimum thermometers of the present invention comprise two glass tubes 1, and described two glass tubes about 1 split, and establish sealing bulb, 2 on one, divide into open safe chamber 4, and another root is oppositely put it; The low-density temperature sensing liquid is filled in the upper end in the every glass tube 1, lower end filling high-density feel geothermal liquid, joint are provided with and add the red display agent in the low-density temperature sensing liquid of 3, two glass tube 1 middle and upper parts of pointer, for guaranteeing that temperature sensing liquid does not leak, safe chamber also adopts hook-type when the lower end.
Glass tube 1 is installed in index dial 9 fronts, and index dial 9 back are provided with magnetic stripe plate 7, is provided with spring 8 between magnetic stripe plate 7 and the bonnet 11, glass tube 1 the place ahead is provided with protecgulum 10, and left and right sides index dial scale value is reverse, and one is upper just bearing down, just lower negative on the another one, form two watch core structures.Among the figure left side be upper negative lower just, the right is upper just lower bearing.
Glass tube 1 length is 200mm approximately, and is outer through 4mm, internal diameter 0.6-0.7mm.
The low-density temperature sensing liquid be proportion 0.8g/cm3, solidifying point for-30 ℃, boiling point be 125 ℃ kerosene.
The proportion of high-density feel geothermal liquid is 1.4-2.0g/cm3, and is transparent.
Safe chamber 4 is hook-type, tapered sphere or ellipse (seeing Fig. 3, Fig. 4, Fig. 5), and 4a wherein, 4b are respectively the sign of safety race 4 on two pipes, and 2a, 2b are respectively the sign of bulb, 2 on two pipes.
Index dial 9 centers are provided with button 12, press the button at 12 o'clock, and index dial 9 can press magnetic stripe plate 7 to move backward, and away from pointer 3, pointer 3 is not attracted by the magnetic stripe on the magnetic stripe plate 7, and the whereabouts resets.
Index dial 9, magnetic stripe plate 7, bonnet 11 and protecgulum 10 adopt ABS plastic to make.
When temperature rose, temperature sensing liquid expanded, and pressure increases, and can avoid glass wall is crushed broken by the air in the compressing secure bubble.
Scaleplate: plastic injection-moulded making, be used for the fixing glass pipe, and printing scale numerical value; Printing scale: be used to refer to current temperature value and the highest and minimum temperature value.Redness is subzero temperature, the black positive temperature; The indication of pointer lower end, the left side be the minimum temperature value, pointer lower end, the right indication be maximum temperature values.
Magnetic stripe: a kind of soft magnetic stripe, plastics add iron powder to be made, and then magnetizes, and draws magnetic stripe magnetic size according to the surface tension of transfer liquid.Be used for attracting the pointer of the right and left glass tube, thus the highest or minimum of record.
Spring: the tinsel coiling forms, and can make magnetic stripe be close to the scaleplate back side.
The magnetic stripe plate: ABS plastic is made, and as the magnetic stripe stationary plane, by spring it is close to the scaleplate back side, press intermediary button after, magnetic stripe leaves the scaleplate back side, the suffered attractive force of pointer reduces, pointer under Action of Gravity Field free-falling to the transfer liquid top.
The thermometric moving process:
Finished product such as Fig. 1, Fig. 2, before the use, button by middle can make magnetic stripe and the scaleplate back side on the press strip that resets form certain distance, thereby makes pointer can not get attractive force on the magnetic stripe, under Action of Gravity Field, free-falling, because the density of lower end transparency liquid is for larger, the gravity of pointer is less than the surface tension of transparency liquid, so pointer falls to the upper end of transparency liquid and stops, this process is called and resets; Release button resets press strip under the acting force of spring, is close to the scaleplate back side, thereby makes magnetic stripe also be close to the scaleplate back side, makes pointer be subject to magneticaction.
When temperature rose, the temperature sensing liquid of left-handed watch core upper end was known from experience expansion, produces larger pressure, promoting the lower end transparency liquid moves, the pointer on the left side stops in the middle of the temperature sensing liquid, and can not descend along with the decline of transparency liquid owing to being subject to the effect of magnetic stripe magnetic force at this moment.The transparent feel geothermal liquid of right watch core lower end also expands, and promotes the upper end red liquid and moves up, and the pointer on the right also has been subject to the magneticaction of magnetic stripe, but magnetic force is less than the expulsive force of temperature-sensitive transparency liquid, so new liq can push pointer move up.
Current Temperatures should be read the corresponding scale value of transparency liquid liquid level, because the temperature sensing liquid liquid level of left side watch core and transparency liquid liquid level are same surfaces; The temperature sensing liquid on the right is exactly transparency liquid, is the measured temperature value so directly read the scale value on transparency liquid surface.Artificially identical graduation is made at two ends, the left and right sides.
Recording process: (left side record lowest temperature, the right record highest temperature)
1, when measured temperature when a certain maximum temperature point (such as 35C), scale corresponding to the transparency liquid of the right and left upper end should be current measured temperature 35C; The right-hand member pointer is subjected to the promotion of high-density feel geothermal liquid (transparency liquid), and its lower end also can rest on the 35C line; When drop in temperature, right-hand member high-density feel geothermal liquid (transparency liquid) volumetric contraction, liquid level is to moving down, and the right pointer rests in the middle of the red kerosene liquid under the effect of magnetic force;
2, when measured temperature to a certain minimum temperature point (as-10C) time, scale corresponding to the transparency liquid at two ends, left and right sides upper end should be current measured temperature-10C; The left end pointer is promoted by transparency liquid, and its lower end also stops-the 10C line; When temperature rises, low-density temperature sensing liquid (kerosene) volumetric expansion, liquid level is to moving down, and left side pointer rests in the middle of the temperature sensing liquid (kerosene) under the effect of magnetic force.
3, when measured temperature be-10C and 35C between the time (such as 20C), the pointer at two ends is through the effect of the highest temperature and lowest temperature, be pushed to the highest and the minimum temperature point by transparency liquid, under the effect of magnetic stripe attractive force, rest on this 2 point, so can know maximum temperature and the minimum temperature that this thermometer is measured by the corresponding temperature value in read pointer lower end.Pointer lower end, the left side is shown as the minimum temperature value; Pointer lower end, the right is shown as maximum temperature value.
