As shown in Figure 1, temperature attention device of the present invention comprises base element 1, caution part 2, cover part 3, thrust spring 4, bimetallic strip 5, card-bit part 6, tension spring 7 and cover piece 8.
Wherein, caution part 2 is a cylindrical shape, and its front end cylindrical portions may outside surface has alert flag.Alert flag can have various ways, for example is the red or yellow coating that is coated with on the surface, or the mark of " * " symbol or similar lightning etc., thereby make undesired the getting final product of judgement the temperature here so long as can let people's naked eyes see significantly.The inside of caution part 2 has cavity to hold thrust spring 4.Thrust spring 4 and the 2 coaxial settings of caution part move along its axis direction thereby promote caution part 2.One end of thrust spring 4 is against on the inside surface of caution part 2 cavitys, and the other end is against on cover part 3 inwalls.
The cover part 3 cover on the caution part 2 on, the enough ambassadors of its volume its have cavity hold the caution part 2, and the caution part 2 can in cavity, move along axis direction.When caution part 2 moves certain distance, the alert flag of front end is exposed outside the cover part 3 so that one can observe that alert flag.Outside surface color and the alert flag of cover part 3 should distinguish, and best is, cover part 3 is identical with the surrounding environment color of the position of being installed, so that alert flag can clearly be found out when exposing.
Fluted on base element 1 upper surface; Bimetallic strip 5 is positioned at groove; And the concave surface of bimetallic strip 5 is up, and the convex surface of bimetallic strip 5 is facing to groove floor, then under the normal temperature contact 50 towards base element 1 upper surface ground perk; And when temperature reached or surpass preset value, contact 50 was to the distortion of the bottom surface of groove.
Cover piece 8 is housed on the base element 1, and cover piece 8 is enclosed in bimetallic strip 5 in the groove.Through screw bimetallic strip 5 is fixedly installed on the back side of cover piece 8, makes between convex surface and the groove floor of bimetallic strip and leave the gap, to guarantee the deflection of bimetallic strip.The material such as the aluminium of cover piece 8 preferred good heat conductivity, then the temperature amount of base element 1 can be transmitted on the cover piece 8 well, and then passes to sheet metal.Because sheet metal is very thin, and groove is also very shallow, and the air that therefore is sealed in the groove is less, then radiation and the energy that consumes is little; Simultaneously, the good heat-transfer of cover piece of aluminum 8 and base element 1 makes that temperature that bimetallic strip 5 sensed is consistent with the temperature of cover piece 8, base element 1 and tested position basically, thereby improves thermometric accuracy greatly.
