Abstract
The utility model relates to a double-spot switch for a double-control electric heating temperature controller, which is composed of a containing box and an extensional power supply connection post. The both sides of the outer side of a ceramic dish of the containing box are provided with two grooves for containing thermosensitive elements, and through core holes for fixing the thermosensitive elements and switch top posts are arranged on the inner walls of the grooves. A ceramic base and the ceramic dish are symmetrically provided with two through holes. Two normal close elastic contacts are arranged in the box of the ceramic base, and each elastic trip of the normal close elastic contacts bears the movement of the two top posts. A T-shaped lug boss is arranged on the section of the ceramic base, and two elastic contacts and a Y-shaped fixed wafer are respectively fixed on the lug boss and are led to be communicated with the power supply connection post. Compared with a single-spot switch, the utility model has the advantages of novel function and strong practicability.
Description
The utility model relates to a kind of two point switch that is used for two control electric heating thermostats.
Along with improving constantly of expanding economy and living standards of the people, increasing unit, public place and the family various electric water boilers such as electric water heater, insulating pot, electric water boiling bucket, electric water tank of having purchased, the switch that these electric water boiler joining powers adopt mostly is the single-point switch, the break-make of switch realizes the function to thermoelectric heating device heating and disconnected heat, its defective is that function ratio is more single, when heated condition down during unmanned guard, easily dryout water and cause the electrical equipment accident.
The purpose of this utility model is to provide a kind of two point switch that is used for two control electric heating thermostats, can use with two control electric heating thermostat couplings, realizes the function of insulation and anti-dry.
For achieving the above object, the utility model is taked following design: this two point switch that is used for two control electric heating thermostats, the power supply that fastens the container that forms and extension by ceramic dish and ceramics seat connects post and forms, be provided with the grooves of two device temperature-sensitive elements on both sides, the ceramic dish outside, have the through-core hole of stationary heat photosensitive elements and switch fore-set on the groove inwall: ceramics seat and ceramic dish are arranged with two through holes that are used for assembling with controlled electroheat member fastening usefulness; Two normally closed resilient contacts are arranged in the ceramics seat box, and its each flexure strip is stressed respectively in the motion of two fore-sets; One "T"-shaped boss is arranged on the section of ceramics seat, fix two resilient contacts and " Y " shape fixed touching plate on the "T"-shaped protruding platform respectively, this two resilient contact and " Y " shape fixed touching plate draw to be put UNICOM's power supply and connects post.
Two resilient contacts are fixed on the parallel lines of the "T"-shaped boss of ceramics seat, and fixed touching plate is fixed on the vertical line of boss, two resilient contacts and the normally closed joining of fixed touching plate two terminal contacts.
Be provided with the positive stop lug boss that four restriction ceramic dish and ceramics seat fasten the degree of depth in the ceramics seat, two ∩ shape positive stop lug boss wherein are useful on the through hole that assembles fastening usefulness with controlled electroheat member.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is ceramic dish master, side, backsight structural representation
Fig. 3 is ceramics seat master, backsight and B-B cutaway view
As Fig. 1, Fig. 2, shown in Figure 3, the power supply that the utility model mainly fastens the container that forms and extension by ceramic dish 1 and ceramics seat 2 connects post 3 and forms, be provided with the groove of two device temperature-sensitive elements 4 on both sides, the ceramic dish outside, have the through-core hole 101,102 of stationary heat photosensitive elements 4 and switch fore-set 7 on the groove inwall; Ceramics seat and ceramic dish are arranged with two through holes 202,103 that are used for assembling with controlled electroheat member fastening usefulness; Two normally closed resilient contacts 5 are arranged in the ceramics seat box, and its each flexure strip 501 is stressed respectively in the motion of two fore-sets; One "T"-shaped boss 201 is arranged on the section of ceramics seat, fix two resilient contacts and " Y " shape fixed touching plate 501 on the "T"-shaped protruding platform respectively, this two resilient contact and " Y " shape fixed touching plate draw to be put UNICOM's power supply and connects post 3.Two resilient contacts 5 are fixed on the parallel lines of the "T"-shaped boss of ceramics seat, and fixed touching plate is fixed on the vertical line of boss, two resilient contacts and the normally closed joining of fixed touching plate two terminal contacts.
Be provided with the positive stop lug boss 6,8 that four restriction ceramic dish and ceramics seat fasten the degree of depth in the ceramics seat, two ∩ shape positive stop lug boss 6 wherein are useful on the through hole 202 that assembles fastening usefulness with controlled electroheat member.
Components such as container adopt the ceramic-like heat proof material to make.
During use, be communicated with the two control electric heating thermostats in being installed on electric water boiler, utilize temperature-sensitive element (being the constant temperature sheet metal) rising-heat contracting-cold characteristic to make it do mechanical movement, promote ceramic fore-set 7, by this sudden change mechanical force, normally closed resilient contact is disconnected or joining.When water burnt to design temperature (being generally fluidizing point 100 degree), temperature-sensitive element action drives fore-set 7 disconnected resilient contact, cuts off the electric heater power supply, and no longer heating enters insulation and anti-dry state.When temperature reduced, bimetal leaf retracted to the original position state, and makes normally closed resilient contact get back to closure state, power connection, and electric heater continues heating.
The utility model has the advantages that: than the single-point on-off ratio, function is new, and is practical.
