Description

Temp sensing controller

Technical field

The utility model relates to the temp sensing controller that uses in a kind of wireless liquid heater.

Background technology

Existing anti-repetition dry combustion method function temp sensing controller is employed in sets up overbalance central elastic frame under the bimetallic actuator; On this elastic shelf catch bar is housed; And in the housing of temperature control main body, be provided with oblique device, and cooperate in order to movable cam with the temperature control body interior, be implemented in connector and cooperate a time-out with main body; Bimetallic strip on the support is cut off the power supply by thermal actuation, puts into realization and reset again again after need be artificially connector and temperature control body portion being left.Though this kind structure can reach anti-repetition dry combustion method function, and is too numerous and diverse on the constructional device of design, existence surpasses three being in transmission connection; And this connection is processed by plastic parts; In the use of reality, occur transmission easily and have some setbacks, even catching phenomenon, the normal functions of use of consumer influenced.Because mechanism element is numerous, material cost improves simultaneously, also brings difficulty to workman's assembling, and the assembling qualification rate is affected.

Summary of the invention

The purpose of the utility model provides the temp sensing controller of a kind of simple in structure, dependable performance, the anti-repetition dry combustion method function of tool.

For realizing above-mentioned purpose, a kind of temp sensing controller of the utility model comprises main casing, heat-sensitive duplex metal actuator, porcelain rod, conductive reed, conduction static contact; The porcelain rod is located on the main casing and is positioned at the below of bimetallic actuator, and conductive reed is arranged on the below of conduction static contact, and the below of main casing is provided with the connector slot; Have a rotating hole radially on the said main casing; Rotating hole is arranged on the conduction static contact on center position, and a position-limit mechanism is installed in rotating hole, and said position-limit mechanism comprises push rod, spacing tongue, energy-stored spring and stationary shaft; Spacing tongue is articulated in the upper end of push rod; The lower outside of push rod is hinged on the main casing through stationary shaft, establishes energy-stored spring between spacing tongue and the push rod, and push rod can rotate around stationary shaft; The inboard, lower end of push rod is arranged in the connector slot, and the spacing tongue on the push rod is arranged on the adjacent position of conductive reed.

Because the temp sensing controller of the utility model is provided with the position-limit mechanism of conductive reed, when connector in the power supply base inserts the connector slot of main casing, the time; The push rod that promotes position-limit mechanism around stationary shaft to inner rotary; The energy-stored spring compressed energy-storage, spacing tongue leans on last conductive reed, acquires a certain degree when the electrical equipment dry combustion method makes the heat-generating disc surface temperature; Heat-sensitive duplex metal actuator produces kick; When pushing conductive reed open and making its position be lower than spacing tongue, energy-stored spring storage power discharges and makes the spacing tongue revotating card above conductive reed, and anti-its conductive reed resets; When the user need heat up water once more; Need mention kettle, this moment, push rod lost connector to its outside anchorage force, was turned back to original state automatically together with the spacing tongue that is equipped with on it; Conductive reed after the restriction that loses spacing tongue upwards resilience contact with static electric contact piece; Thereby realize resetting of temperature control main body, after the user puts into base with kettle once more, just can switch on and use, therefore avoided electrical equipment unrestricted situation that repeats dry combustion method under the situation that long-time nothing is kept an eye on to take place.Make be able to ensure the serviceable life of electrical equipment, improve the security performance of electrical equipment simultaneously.Its theory structure is comparatively simple, and the cost of material is low.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Embodiment

Like Fig. 1, Fig. 2, shown in Figure 3; A kind of embodiment of the utility model temp sensing controller; Comprise main casing 04, fixed head, heat-sensitive duplex metal actuator 08, porcelain rod 07, conductive reed 05, conduction static contact 06, fixed head is fixedly mounted on the main casing 04, and thermometal braking plate 08 is installed on the fixed head; Porcelain rod 07 is located at the below of thermometal braking plate 08 on the main casing 04; Conductive reed 05 is arranged on the below of conduction static contact 06, is respectively equipped with corresponding dynamic and static contact on conductive reed 05 and the conduction static contact 06, in order to realize the break-make of circuit.

Have a rotating hole 4.1 radially on the said main casing 04; Rotating hole 4.1 is conducting electricity static contact 06 on center position; One position-limit mechanism is installed in rotating hole 4.1, and position-limit mechanism comprises push rod 01, spacing tongue 02, energy-stored spring 03 and stationary shaft 09, and spacing tongue 02 is articulated in an end of push rod 01; The other end of push rod 01 is hinged on the main casing 04 through the stationary shaft 09 in the rotating hole 4.1; Establish energy-stored spring 03 between spacing tongue 02 and the push rod 01, push rod 01 can be around stationary shaft 09 rotation, and the spacing tongue 02 on the push rod 01 can limit conductive reed 05 action.

Its principle is: when the main part of electrical equipment is put into base; Push rod 01 is in power supply base under the effect of connector insertion force; Push rod is the center with the stationary shaft 09 in main casing 04 rotating hole 4.1; Conductive reed 05 direction rotation laterally makes the spacing tongue 02 on the push rod contact with conductive reed 05 positive stop end 5.1, and makes energy-stored spring produce compression.This moment is if electrical equipment produces dry combustion method; When the electrical heating surface temperature acquires a certain degree; Heat-sensitive duplex metal actuator 08 produces kick, promotes porcelain rod 07 and backs down conductive reed 05, is lower than spacing tongue 02 bottom the time when conductive reed 05 backs down the position; Spacing tongue 02 storage power discharges spacing tongue and rotates up, and is stuck in conductive reed 05 top.When the electrical equipment temperature has reduction slightly, when heat-sensitive duplex metal actuator resets, the thrust forfeiture of porcelain rod; Conductive reed automatically reset because of spacing tongue 02 be stuck in its top restricted; Thereby realize anti-repetition dry combustion method function,, need mention the main part of electrical equipment if the user wants to reuse when heating up water; This moment, push rod 01 lost connector to its outside anchorage force; Push rod 01 is turned back to original state automatically together with the spacing tongue that is equipped with on it 02, conductive reed after the restriction that loses spacing tongue 02 upwards resilience contact with conduction static contact 06, thereby the resetting of realization temperature control main body; After the user puts into base with the main part of electrical equipment once more, just can switch on and use, this has just been avoided electrical equipment because the long-time situation of not having unrestricted repetition dry combustion method under the situation of keeping an eye on of user takes place.Make be able to ensure the serviceable life of electrical equipment, improve the security performance of electrical equipment simultaneously.
