Detailed Description

The present invention will be further described with reference to the following examples.

Examples

A coupler capable of improving heat preservation effect as shown in fig. 1-5, which is mainly used in an electric kettle, and comprises a grounding fixing plate 1, a temperature control base 2, an action rod 3, an L pole terminal 4, an L pole action reed 5, an N pole terminal 6 and an N pole action reed 7, wherein the action rod is movably connected with the temperature control base (the structure is the prior art, and is not described in detail herein), two bimetallic strips are connected on the grounding fixing plate for breaking a circuit due to environmental overheating, a steam action strip 13 is installed on the temperature control base, the steam action strip is also a bimetallic strip, and the steam action strip is deformed under the influence of steam temperature, so as to push the action rod to act to realize tripping of a switch of the electric kettle, and it is worth noting that in order to enable the position of the coupler to achieve a certain heat preservation effect, a groove 11 for installing heat preservation material is arranged on the grounding fixing plate 1, the board that direct joint insulation material made in the recess 11, the board that insulation material made is the ordinary insulation material product in the market, and the board that insulation material made is prior art, does not do too much here and has elucidated, for insulation material does not influence the electric kettle overheat protection effect, this recess 11 staggers dry combustion method screening glass setting. This also enables the dry-fire protection sheet to provide protection against overheating. The dry burning protection sheet is a bimetallic strip 10.

In order to fix the heat insulating material at the position of the groove 11 of the grounding fixing plate 1, the inner wall or the inner surface of the groove 11 is provided with a clamping part 12 for clamping the heat insulating material, and the heat insulating material is arranged in the groove 11 and clamped by the clamping part 12. The clamping part 12 is two bending plates, and the bending part and the grounding fixing plate 1 are in an integrated structure. In the embodiment, the clamping part is designed into a thin plate integrated with the grounding fixing plate 1, and the thin plate has elasticity, so that the heat-insulating material is clamped in the clamping part and then is clamped elastically, and the assembly is convenient and rapid. And the clamping part 12 is convenient to process.

The grounding fixing plate 1 is connected with a movable rod fixing seat 9, the movable rod 8 is movably connected onto the movable rod fixing seat 9, one end of the movable rod 8 is abutted to the double-gold-piece 10, and the other end of the movable rod is abutted to the action reed. In order to prevent the phenomenon of clamping between the traditional movable rod 8 and the movable rod fixing seat 9 from causing abnormal tripping, the movable rod 3 is movably connected with the temperature control base 2 in a rotatable manner, a push rod 31 extending to at least one of the bimetallic strips 10 is arranged on the movable rod 3, a pushed part 51 extending to the range of the moving track of the movable rod 3 is arranged on at least one of the movable reed, the pushed part and the movable reed are in an integrated structure, the push rod 31 pushes the movable rod 3 to rotate integrally when the bimetallic strip 10 deforms, and the pushed part of the movable reed pushes the movable reed to separate the movable reed from a wiring terminal when the movable rod 3 rotates. The push rod 31 part arranged on the action rod 3 can drive the action rod 3 by the double-gold-plated piece 10 when the double-gold-plated piece 10 is deformed by heat, and the action rod 3 pushes and pushes the action reed to open a circuit, thereby playing the role of protecting the circuit.

In order to prevent the elastic force of the action reed from being insufficient to jack up the movable rod 8 when the movable rod 8 is clamped on the movable rod fixing seat 9, the action rod 3 is provided with an abutting part 32 extending to the lower part of each action reed, and the abutting part 32 pushes the action reed to abut against the wiring terminal in the uplifted state of the action rod 3. Through the manual action pole 3 of pressing down, the butt portion 32 top of action pole 3 pushes away the action reed and promotes the movable rod 8 and move up, because manual power is great, can overcome the power that the movable rod 8 blocked on the movable rod fixing base 9 completely, plays the manual mesh that resets when the dead action reed of movable rod 8 card can not reset.

In order to improve the pushing force of the bimetallic strip 10 at the position of the push rod 31 or the movable rod 8, a fixed protrusion 14 for fixedly supporting the bimetallic strip 10 is arranged on the grounding fixed plate 1, and the fixed protrusion 14 is arranged far away from the push rod 31 and/or the movable rod 8. The number of the fixing protrusions 14 is at least two, and the fixing protrusions and the grounding fixing plate 1 are of an integrated structure. The bimetallic strip 10 will deform when heated, the fixing protrusion 14 cannot deform due to the additional arrangement of the fixing protrusion 14, and the deformation force at the position far away from the fixing protrusion 14 will become larger, so that the elastic restoring force is larger, and the bimetallic strip is easier to reset.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
