Owing to adopted said method, the utility model collection thermometer, automatic and artificial warning, doorbell are one, and can optionally use wherein a certain function, be particularly useful for family, it not only provides the temperature of every day for you, but but also the automatic forecasting fire alarm also can report to the police when running into accident, can work as doorbell at ordinary times again and use, and also have the effect of decorating.

Below just the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is a principle schematic of the present utility model: among the figure 1, left side control temperature pointer 2, temperature pointer 3, Celsius and Fahrenheit coil 4 quarter, right control temperature pointer 5, rotating shaft 6, tinsel 7, hairspring 8, bell and bimetallic strip stiff end 9, bimetallic strip 10, steel bell 11, the electromagnet 12 of electric bell, battery case (reverse side).

Fig. 2 is the rotating shaft stereograph of metallic thermometer: among the figure 1, left side control temperature pointer 2, temperature pointer 3, left side indicator knob 4, right control temperature pointer 5, rotating shaft 6, tinsel 7, pointer contact, the right 8, pointer contact, the left side 9, temperature pointer contact 10, the right indicator knob

Fig. 3 is the right control temperature pointer view

Fig. 4 is a circuit diagram of the present utility model: among the figure 2, spring leaf 3, armature 4, screw 5, doorbell button 6, artificial alarm switch 7, electromagnet

Bimetallic strip among Fig. 1 (9) encloses into scroll, and is fixed in the steel bell (10).One end and bell are fixed together (8), and the other end hauls with tinsel (6) and walks around rotating shaft (5) and hang on the spring (7).Rotating shaft (5) is gone up except that the temperature pointer is arranged (2), about control temperature pointer (1,4) in addition.When bimetallic strip (9) is subjected to temperature and influences, will expand or shrink, though it this expand and one contract very smallly, reach rotating shaft (5) with transmission mechanism tinsel (6) and amplified through temperature pointer (2) again, just can (3) obviously find out from the quarter dish.

The left and right sides pointer (1,4) on a little higher than plane that coexists of temperature pointer (2) among Fig. 2.They can only be that use in left and right sides at the center with temperature pointer (2), and by left and right sides indicator knob (3,10) control with gear shaft from rotating shaft (5) center respectively, three pointers (2,1,4) be to be enclosed within respectively in the rotating shaft (5), their afterbody all is being with power contact (7,8,9), and can rotate around axle (5) separately, the contact (7 of left and right sides pointer, 8) can be enclosed within on the insulating trip of rotating shaft (5) bottom with the power supply sheet that left side place has a round spot, with insulating trip the right is had the power supply sheet of round spot and temperature pointer contact (9) every on top again then.The root of temperature pointer (2) is to one section long insulation distance is arranged between temperature pointer contact (9), sheet metal (6) just go up to drive temperature pointer (2) and contact (9) thereof around this section rotating shaft (5), belong to moving contact, left and right sides pointer (1,4) is controlled temperature in advance and is used, and belongs to stationary contact.When bimetallic strip (9) is subjected to temperature and influences, temperature pointer (2) will be under the effect of transmission mechanism, overlapping or separate with a left side or right pointer (1 or 4), when when they are overlapping or again surpassing original pointer, the contact of afterbody links to each other, and circuit is connected, and has also just started alarm, contact separation in the time of separately, circuitry cuts.But about two pointers (1,4) can not use side by side because side by side the time, no matter temperature is to rise or descend, the contact of temperature pointer (9) all link to each other with the contact (7,8) of left and right sides pointer, so have also just lost the effect of automatic warning.
