The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.
The temperature controller with double circuit temperature control as shown in fig. 1 and 2 comprises a mounting main body, a first static contact 10, a second static contact 20 and a movable contact 30, wherein a temperature sensing metal sheet 40 is arranged on the mounting main body, the temperature sensing metal sheet 40 can deform after sensing temperature change, a push rod 41 is arranged on the temperature sensing metal sheet 40, and the push rod 41 can move up and down when the temperature sensing metal sheet 40 deforms.
The first static contact 10, the second static contact 20 and the movable contact 30 are arranged on the mounting main body, the movable contact 30 is positioned between the first static contact 10 and the second static contact 20, and the first static contact 10 is mounted on the mounting main body and is electrically connected with the first wiring terminal 11; the second stationary contact 20 is mounted on the mounting body and is electrically connected with the second wiring terminal 21; the first connection terminal 11 and the second connection terminal 21 can be connected to different operating circuits.
The movable contact 30 is mounted on the mounting body and is linked with the push rod 41, and the movable contact 30 is electrically connected with the third connecting terminal 31, and the movable contact 30 is used for moving close to the first static contact 10 or the second static contact 20 under the driving of the push rod 41 after the temperature sensing metal sheet 40 senses the temperature change.
Based on the above structure, when the dual-circuit temperature-controlled temperature controller of the present utility model is used, the first connection terminal 11 and the second connection terminal 21 can be connected to two different working circuits respectively, in this embodiment, the first stationary contact 10 is located below the movable contact 30, and the second stationary contact 20 is located above the movable contact 30 for illustration:
when the electric equipment works in the first temperature state, the movable contact can be in contact with the first static contact 10 positioned below to realize electric connection, and at the moment, a circuit accessed by the first wiring terminal 11 and a circuit accessed by the third wiring terminal 31 are in a conducting state, and the first temperature mode working state is started.
And after a period of time, the working temperature reaches a set working temperature, for example, the working temperature reaches a set high-temperature state, at this time, the temperature sensing metal sheet 40 can sense the temperature rise and drive the push rod 41 connected with the temperature sensing metal sheet to move upwards, the push rod 41 can push the movable contact sheet 30 to move upwards to be in contact with the second static contact sheet 20, namely, the working circuit in the first temperature mode is disconnected, at this time, the working circuit led in by the second connecting terminal 21 of the second static contact sheet 20 and the access circuit of the third connecting terminal 31 are in a conducting state, and the working state in the second temperature mode is started.
After the second temperature mode works for a period of time, the temperature is reduced, at this time, the temperature sensing metal sheet 40 senses the temperature change reset, the push rod 41 of the temperature sensing metal sheet 40 moves downwards to drive the movable contact sheet 30 to contact the first static contact sheet 10 again downwards, so as to realize electrical connection, at this time, the working circuit of the second temperature mode is disconnected, and the first temperature working mode is restarted.
In this way, the temperature sensing metal sheet 40 can sense the temperature change, so as to drive the movable contact sheet 30 to be in electrical contact with the first static contact sheet 10 or the second static contact sheet 20, so that the switching of different working circuits is realized, and different working modes are started at different temperatures, thereby realizing temperature control.
Of course, in the two modes of operation illustrated in the embodiment, the temperature sensing metal sheet 40 drives the movable contact sheet 30 to move upward to electrically contact with the second static contact sheet 20 located above, and the temperature sensing metal sheet 40 drives the movable contact sheet 30 to move downward to electrically contact with the first static contact sheet 10 located below when the temperature is reduced, but in other cases, the temperature sensing metal sheet 40 may also drive the movable contact sheet 30 to move upward to electrically contact with the second static contact sheet 20 located above when the temperature is reduced, and the temperature sensing metal sheet 40 drives the movable contact sheet 30 to move downward to electrically connect with the first static contact sheet 10 located below when the temperature is increased, specifically, the temperature sensing metal sheet 40 is selected according to the deformation direction of the temperature sensing metal sheet 40.
Further, one end of the temperature-sensing metal sheet 40 is connected to the mounting body, and the push rod 41 is connected to the end of the temperature-sensing metal sheet 40 away from the mounting body; the width of the temperature-sensitive metal sheet 40 gradually decreases from one end near the mounting body to one end far from the mounting body.
The specific push rod 41 is connected to the end portion of the temperature sensing metal sheet 40 far away from the installation main body, and the width of the temperature sensing metal sheet 40 gradually decreases from one end close to the installation main body to one end far away from the installation main body, so that one end of the temperature sensing metal sheet 40 has a larger temperature sensing surface, the temperature change can be received to a greater extent, and the width of the end portion of the temperature sensing metal sheet 40 of the push rod 41 is smaller, so that the temperature sensing metal sheet 40 is convenient to deform at the portion.
It should be noted that the push rod 41 in this embodiment may be implemented by a knob structure.
Further, the temperature-sensitive metal sheet 40 is a bimetal sheet. The bimetal is formed by at least two metal layers with different expansion coefficients, and because the thermal expansion coefficients of the metals of the layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, the whole bimetal is bent to one side of the passive layer to deform, and then the push rod 41 is driven to move up and down, so that the temperature control is realized.
Further, a metal reed 42 is arranged on the mounting main body, one end of the metal reed 42 is connected with the push rod 41, and the other end of the metal reed 42 is provided with a movable contact piece 30; the third connecting terminal 31 is electrically connected with the metal reed 42, that is, when the push rod 41 moves up and down, the metal reed 42 can deform better, so that the movable contact 30 connected with the metal reed can be driven to contact with the first static contact 10 or the second static contact 20, the situation of insufficient deformation of the movable contact 30 is compensated, and the elastic force provided by the metal reed 42 can also drive the movable contact 30 to keep a contact conduction state with the corresponding static contact.
Further, an adjusting rod 60 is arranged on the mounting main body, and the adjusting rod 60 is arranged above the metal reed 42 and can move close to or away from the metal reed 42. Specifically, after the adjusting lever 60 moves close to the metal reed 42, the acting force applied to the metal reed 42 is larger, so that the temperature sensing metal sheet 40 needs to have larger deformation to push the movable contact sheet 30 on the metal reed 42 to move up and down, and thus temperature control switching can be realized when the temperature change is larger, while after the adjusting lever 60 moves away from the metal reed 42, the acting force applied to the metal reed 42 is smaller, so that the temperature sensing metal sheet 40 needs smaller deformation to push the movable contact sheet 30 on the metal reed 42 to move up and down, and temperature control switching can be realized within a small range, and thus, the adjustment of the temperature control range can be realized through the up-down movement of the adjusting lever 60.
Further, the ceramic ring assembly comprises a first ceramic ring 51, a second ceramic ring 52, a third ceramic ring 53 and a fourth ceramic ring 54, wherein the first ceramic ring 51, the second ceramic ring 52, the third ceramic ring 53 and the fourth ceramic ring 54 are sequentially stacked from bottom to top; the first wiring terminal 11 and the first static contact 10 are clamped between the first porcelain ring 51 and the second porcelain ring 52; the second wiring terminal 21 and the second static contact piece 20 are clamped between the second porcelain ring 52 and the third porcelain ring 53; the third connecting terminal 31 is clamped between the third porcelain ring 53 and the fourth porcelain ring 54 and is electrically connected with the movable contact 30; the temperature sensing metal sheet 40 is arranged at the bottom end of the first porcelain ring 51.
In this way, the temperature sensing metal sheet 40, the first static contact sheet 10, the first connecting terminal 11, the second static contact sheet 20, the second connecting terminal 21, the movable contact sheet 30 and the third connecting terminal 31 are assembled in a separated manner through the first porcelain ring 51, the second porcelain ring 52, the third porcelain ring 53 and the fourth porcelain ring 54, and the insulation effect between the two porcelain rings is better.
In addition, the above-described structure of the adjusting lever 60, the metal reed 42, and the like may be used as a mounting base for mounting the ceramic ring structure.
Further, the first ceramic ring 51, the second ceramic ring 52, the third ceramic ring 53 and the fourth ceramic ring 54 are sequentially connected and fixed by bolts from bottom to top, that is, when assembling, after the corresponding connection terminals and the contact structure are assembled between two adjacent ceramic rings, the bolts are connected in the corresponding through holes of the first ceramic ring 51, the second ceramic ring 52, the third ceramic ring 53 and the fourth ceramic ring 54 in a penetrating manner, so that assembling is realized, and assembling and disassembling are convenient.
It will be apparent to those skilled in the art from this disclosure that various other changes and modifications can be made which are within the scope of the utility model as defined in the appended claims.
