Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1,2 and 3, the Hygrothermograph 100 that provides for the utility model embodiment.This Hygrothermograph 100 comprises dial plate 10, temperature pointer 21, humidity pointer 31, temperature indicating mechanism and humidity indicating mechanism.As shown in Figure 2, temperature indicating mechanism comprises temperature axostylus axostyle 22, temperature rotating shaft 24, temperature shell fragment 26, is arranged on the dial plate 10 and the temperature axle sleeve 27 and the temperature cover plate 29 of sheathed temperature axostylus axostyle 22.Similarly, humidity indicating mechanism comprises humidity axostylus axostyle 32, humidity rotating shaft 34, humidity shell fragment 36, is arranged on the dial plate 10 and the humidity axle sleeve 38 and the humidity cover plate 39 of sheathed humidity axostylus axostyle 32.Temperature indicating mechanism and humidity indicating mechanism are installed on the dial plate 10 at intervals.
As shown in Figure 1, dial plate 10 can be a disk, has a surface 12, this surface 12 is provided with temperature scale line 14 and humidity scale mark 16, roughly be circle-shaped distribution, people relatively are concerned about environment temperature usually, so temperature scale line 14 is provided with bigger zone, humidity scale mark 16 also can be made change certainly according to actual needs then with less zone.In addition, temperature scale line 14 and humidity scale mark 16 are also divided a plurality of zones, for example,-30 ℃ to-10 ℃ intervals are set at anti-frostbite district,-10 ℃ to 18 ℃ interval is set at cold district, 18 ℃ to 29 ℃ interval is set at comfort zone, and 29 ℃ to 40 ℃ interval is set at hot district, and 40 ℃ to 50 ℃ interval is set at the heatstroke prevention district.On humidity scale mark 16, be that 20% to 40% interval is set at the low humidity district with humidity, 40% to 70% interval is set at the comfort humidity district, and 70% to 100% interval is set at the high humility district.
The surface 12 of dial plate 10 is covered with a translucent cover 19, for example is a domed cloche.Also at least two reference columns 18 can be set on the dial plate 10, present embodiment is two, lays respectively at two temperature end points places of temperature scale line 14, can determine the position of temperature and humidity scale mark 14, the 16 relative drain pans on the dial plate 10 by reference column 18.
Shown in Fig. 2 and 3, in temperature indicating mechanism, temperature cover plate 29 has spacing hole 292, and an end of temperature shell fragment 26 connects and is surrounded on temperature rotating shaft 24, and the other end passes the spacing hole 292 of temperature cover plate 29.The multilayered metal film that temperature shell fragment 26 forces together and forms for two or more metal film stacks, it presents the spiral web-like and is surrounded on temperature rotating shaft 24, and this spiral web-like helps improving sensitivity of thermometry.
The temperature-measurement principle of this temperature indicating mechanism is: when the temperature change of the multilayered metal film of temperature shell fragment 26, each layer expansion of metal or amount of contraction do not wait, and make helical coil roll or unclamp.Because an end of helical coil is fixed in temperature rotating shaft 24, therefore, when bimetallic strip is experienced temperature variation, temperature rotating shaft 24 is rotated, drive the temperature pointer 21 that can freely rotate simultaneously and rotate, temperature pointer 21 can indicate temperature on temperature scale line 14.
Humidity indicating mechanism is similar to temperature indicating mechanism, and for example, an end of humidity shell fragment 36 connects and is surrounded on humidity rotating shaft 34, and the other end passes humidity cover plate 39.The multilayered metal film that humidity shell fragment 26 forces together and forms for two or more metal film stacks, it presents the spiral web-like and is surrounded on humidity rotating shaft 34, and this spiral web-like helps improving hygrometric sensitivity, and humidity shell fragment 26 also can adopt the macromolecular material of induction humidity.Wherein, an end of humidity axostylus axostyle 32 is arranged in the humidity rotating shaft 34 movably.Humidity axostylus axostyle 32 is inserted in the humidity axle sleeve 37 free to rotately, and humidity axle sleeve 37 passes dial plate 10 and is arranged on it.Humidity cover plate 39 structures are identical with temperature cover plate 39, do not repeat them here.Two mechanism's differences are, humidity rotating shaft 34 and humidity axostylus axostyle 32 form that is structure as a whole, and humidity pointer 31 is sheathed on the top that humidity axostylus axostyle 32 stretches out dial plate 10.And, all corresponding element of each element of humidity indicating mechanism less than temperature indicating mechanism.Humidity axostylus axostyle 32 and temperature axostylus axostyle 22 standoff distance D, for example, distance D is 20 millimeters, the total height H of Hygrothermograph 100 can be 32 millimeters.
The hygrometric principle of humidity indicating mechanism is: when the humidity of the sheet metal of humidity shell fragment 26 changes, corresponding generation temperature variation, under the different temperature, the degree difference of each layer metal rising-heat contracting-cold, the degree of crook difference of sheet metal, thus drive humidity pointer 31 indicating graduations, and the humidity scale mark can convert by the dry and wet temp difference and get relative humidity, therefore, shown in Figure 2 is a not scale of five equilibrium.
Wherein, temperature pointer 21 and humidity pointer 31 can adopt aluminum, and temperature axle sleeve 27 and humidity axle sleeve 37 can adopt stainless steel or copper product, and humidity shell fragment 36 also can adopt copper sheet, temperature cover plate 29 and humidity cover plate 39 can adopt aluminum, and dial plate 10 can adopt aluminium or plastics.Certainly each element also can adopt other materials, is not limited to the above material of enumerating.
In addition, as shown in Figure 4, Hygrothermograph 100 also comprises a drain pan 40, and itself and dial plate 10 form the space of ccontaining temperature indicating mechanism and humidity indicating mechanism.Many group flutings 42 can be set, fixing Hygrothermograph 100 on the sidewall of drain pan 40 so that be inserted on any base.The bottom surface of drain pan 40 offers deep-slotted chip breaker 44, it is corresponding to the position of temperature indicating mechanism or humidity indicating mechanism, see through these deep-slotted chip breaker 44 scalable reference temperature or reference humidity, because when Hygrothermograph 100 dispatches from the factory the initial value humiture may the value of losing contact with reality, so just can come the adjustment humiture by deep-slotted chip breaker 44 usefulness proper implements.As shown in Figure 2, Hygrothermograph 100 also comprises an outer ring 46, and it is buckled into translucent cover 19, dial plate 10 and drain pan 40 and is structure as a whole.
The Hygrothermograph that the utility model embodiment provides is installed on temperature indicating mechanism and humidity indicating mechanism on the same dial plate 10, abundant dial plate 10 inner utilization spaces, with two organization's integration is one, and each element adopts axial mounting structure, makes one-piece construction become comparatively compact.Temperature indicating mechanism and humidity indicating mechanism all adopt the spring-piece type sensing element, can improve the sensing precision of temperature and humidity.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
