Description

Technical Field

[0001] The invention relates to the technical field of liquid electric heating vessels, in particular to a coupler with segmented disconnection. Background Art

[0002] The coupler is applied to liquid electric heating vessels, such as electric tea sets, and usually includes a lower coupler component and an upper coupler component. The lower coupler component includes a main shell plastic part and a first electrode sheet, a second electrode sheet, and a grounding electrode sheet respectively placed on the main shell plastic part, and the first electrode sheet and the second electrode sheet are respectively provided with contact points; the upper coupler component includes a main body plastic part and a first conductive ring, a second conductive ring, a moving spring sheet and a static electrode sheet, and a grounding electrode plug assembly respectively arranged on the main body plastic part. There is a problem with the existing coupler. When the vessel is coupled to the base or disconnected, the contact points of the electrode sheet of the lower coupler component and the conductive ring of the upper coupler component are prone to electrode arcing and carbon deposition, thereby affecting the service life. Summary of the invention

[0003] The main purpose of the present invention is to provide a coupler with segmented disconnection and improved service life.

[0004] To achieve the above-mentioned object, the present invention provides a coupler with segmented disconnection, comprising a lower coupler assembly and an upper coupler assembly, wherein the lower coupler assembly comprises a main housing plastic part and a first electrode sheet, a second electrode sheet and a grounding electrode sheet respectively placed on the main housing plastic part, and the first electrode sheet and the second electrode sheet are respectively provided with contact points; the upper coupler assembly comprises a main body plastic part and a first conductive ring, a second conductive ring, a moving spring sheet and a static electrode sheet, and a grounding electrode sheet assembly respectively arranged on the main body plastic part, and the main body plastic part is also provided with a segmented disconnection device, The segmented disconnecting device includes a segmented disconnecting top rod and a disconnecting top rod elastic part. One end of the segmented disconnecting top rod passes through the main body plastic part and cooperates with the main shell plastic part of the lower coupler assembly, and is vertically slidable. The disconnecting top rod elastic part applies a force to the segmented disconnecting top rod part in the direction of the main shell plastic part. The segmented disconnecting top rod part has a first position in which the movable spring sheet and the static pole sheet are kept disconnected after moving toward the main shell plastic part, and a second position in which the movable spring sheet and the static pole sheet can be closed after moving away from the main shell plastic part.

[0005] By adopting the above technical solution, when the lower coupler assembly and the upper coupler assembly are partially separated, the segmented disconnecting top rod moves downward under the force of the disconnecting top rod elastic member, pressing the movable spring to operate, so that the contact contacts provided on the first electrode sheet and the second electrode sheet on the lower coupler assembly are still in the connected state with the first conductive circle and the second conductive circle of the upper coupler assembly, thereby disconnecting the load circuit in advance, and when the lower coupler assembly and the upper coupler assembly are completely separated again, the contact contacts on the lower coupler assembly are completely disconnected from the first conductive circle and the second conductive circle on the upper coupler assembly. Correspondingly, when the lower coupler assembly and the upper coupler assembly begin to couple, the segmented disconnecting push rod is acted upon by the disconnecting push rod elastic member, so that the moving spring piece and the static pole piece are in a disconnected state, so that the contact point on the lower coupler assembly and the first conductive circle and the second conductive circle on the upper coupler assembly are not energized at first; when the lower coupler assembly and the upper coupler assembly are coupled in place, the segmented disconnecting push rod is acted upon by the thrust of the main housing plastic part of the lower coupler assembly, so as to overcome the force of the disconnecting push rod elastic member, so that the moving spring piece and the static pole piece are in a closed state, so that the contact point on the lower coupler assembly and the first conductive circle and the second conductive circle on the upper coupler assembly are energized. Therefore, the first conductive circle and the second conductive circle will not produce the phenomenon of electrode arcing and carbon deposition, thereby extending the service life of the product.

[0006] Furthermore, a disconnecting ejector rod limiting groove is vertically arranged on the main body plastic part, and the segmented disconnecting ejector rod member can be slidably arranged in the disconnecting ejector rod limiting groove.

[0007] Such arrangement makes the structure compact and stable.

[0008] Furthermore, the segmented disconnecting ejector rod comprises a main body, the main body is provided with a protruding arm protruding toward the movable spring sheet, and the disconnecting ejector rod limiting groove is provided with an opening for the protruding arm to slide vertically.

[0009] This arrangement further improves stability.

[0010] Furthermore, a convex ring is provided on the main body, the convex arm is provided on the convex ring, a gap is provided between the convex arm and the main body, the disconnect push rod elastic member is provided as a spring, the spring is sleeved on the convex ring, and the gap positions the spring.

[0011] Such arrangement makes the structure compact and stable.

[0012] Furthermore, the segmented disconnecting push rod and the static pole piece are arranged on the same side of the moving spring piece, and an extension wall is arranged at the opening, and the extension wall is placed between the protruding arm and the moving spring piece.

[0013] Such an arrangement further makes the structure compact and stable. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the segmented disconnecting top rod 401 passes through the main body plastic member 201 and cooperates with the main shell plastic member 101 of the lower coupler assembly 1, and is vertically slidable. The disconnecting top rod elastic member 402 applies a force to the segmented disconnecting top rod 401 in the direction of the main shell plastic member 101. The segmented disconnecting top rod 401 has a first position in which the second movable spring piece 206 and the second static pole piece 207 are kept disconnected after moving toward the main shell plastic member 101, and a second position in which the second movable spring piece 206 and the second static pole piece 207 can be closed after moving away from the main shell plastic member 101. When the lower coupler assembly 1 and the upper coupler assembly 2 are partially separated, the segmented disconnecting top rod 401 moves downward under the force of the disconnecting top rod elastic member 402, pressing the second movable spring 206 to operate, so that the contact points 105 provided on the first electrode sheet 102 and the second electrode sheet 103 on the lower coupler assembly 1 are still in the connected state with the first conductive circle 202 and the second conductive circle 203 of the upper coupler assembly 2, and the load circuit is disconnected in advance. When the lower coupler assembly 1 and the upper coupler assembly 2 are completely separated again, the contact points 105 on the lower coupler assembly 1 are completely disconnected from the first conductive circle 202 and the second conductive circle 203 on the upper coupler assembly 2.Correspondingly, when the lower coupler assembly and the upper coupler assembly begin to couple, the segmented disconnecting top rod is acted upon by the disconnecting top rod elastic member, so that the second moving spring and the second static pole piece are in a disconnected state, so that the contact point on the lower coupler assembly and the first conductive circle and the second conductive circle on the upper coupler assembly are still not energized at the beginning; when the lower coupler assembly and the upper coupler assembly are coupled in place, the segmented disconnecting top rod is acted upon by the thrust of the main shell plastic part of the lower coupler assembly to overcome the force of the disconnecting top rod elastic member, so that the second moving spring and the second static pole piece are in a closed state, so that the contact point on the lower coupler assembly and the first conductive circle and the second conductive circle on the upper coupler assembly are energized. Therefore, the first conductive circle and the second conductive circle will not produce the phenomenon of electrode arcing and carbon deposition, thereby extending the service life of the product. It should be noted that the technical solution of the present invention can also be used for couplers without temperature control function, that is, the upper coupler assembly may not include the temperature-sensitive bimetallic strip 210, and it is also feasible to set only one set of moving springs and static pole pieces, see the attached specification.
