Description

Technical Field

[0001] The invention relates to the technical field of liquid electric heating utensils, in particular to a temperature control coupler with dry pot self-locking and segmented disconnection. Background Art

[0002] The temperature control coupler is applied to liquid electric heating vessels, such as electric tea sets, and usually includes a lower coupler assembly and an upper coupler assembly. The lower coupler assembly 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 assembly includes a main body plastic part and a first conductive circle, a second conductive circle, a first moving spring sheet and a first static electrode sheet, a second moving spring sheet and a second static electrode sheet, and a grounding electrode plug assembly respectively arranged on the main body plastic part. The upper coupler assembly also includes a mounting fixed substrate and a temperature-sensitive bimetallic sheet arranged on the mounting fixed substrate, and a transmission push rod is respectively arranged between the temperature-sensitive bimetallic sheet and the first moving spring sheet and the second moving spring sheet. In the existing temperature control coupler, the water in the vessel is boiled dry and after the vessel is dry-boiled, the temperature of the vessel continues to rise, causing the temperature-sensitive bimetallic sheet to move, pushing the transmission push rod to move, pushing the moving spring sheet, separating the moving spring sheet from the static electrode sheet, thereby cutting off the power circuit, causing the electric heating element to be powered off and stop working, and achieving the purpose of temperature control. However, after the electric heater is powered off, the temperature of the vessel decreases, the temperature-sensitive bimetallic strip resumes its action, and the transmission push rod is also reset under the action of the elastic force of the moving spring sheet, so that the moving spring sheet contacts the static electrode sheet, the circuit loop is turned on, and the electric heating element is powered on again to generate heat. This cycle repeats continuously and causes the vessel to be turned on and off continuously, which not only reduces the contact life between the moving spring sheet and the static electrode sheet, but also causes damage to the contacts over time. Once the contacts are fused together, a fire will occur, which seriously affects the safety and life of the product. There is another problem with the existing temperature control coupler. When the vessel is coupled and turned on or disconnected from the base, the contact contacts of the electrode sheet of the lower coupler assembly and the conductive ring of the upper coupler assembly 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 temperature control coupler with dry-cooking self-locking and segmented disconnection, which can improve the safety factor and service life of liquid heating vessels to prevent dry-cooking.

[0004] To achieve the above-mentioned purpose, the present invention provides a temperature control coupler with dry-boiler self-locking and segmented disconnection, including a lower coupler component and an upper coupler component, wherein 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 first moving spring sheet and a first static electrode sheet, a second moving spring sheet and a second static electrode sheet, and a grounding electrode sheet assembly respectively arranged on the main body plastic part, and the upper The coupler assembly also includes a mounting fixed base plate and a temperature-sensitive bimetallic strip arranged on the mounting fixed base plate, and a transmission push rod is respectively arranged between the temperature-sensitive bimetallic strip and the first moving spring strip and the second moving spring strip. The main body plastic part is also provided with an anti-drying pot self-locking device and a segmented disconnecting device; the anti-drying pot self-locking device includes a dry-boiler self-locking push rod, a self-locking push rod elastic part, a transverse locking rod part and a transverse pushing elastic part. One end of the dry-boiler self-locking push 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 self-locking push rod elastic part is pressed against the dry-boiler The self-locking push rod applies a force toward the main shell plastic part, and the transverse push elastic member applies a force to the transverse locking rod member toward the first movable spring piece. A dry pot self-locking driving component is provided between the dry pot self-locking push rod and the transverse locking rod member to drive the transverse locking rod member to move in the direction away from the first movable spring piece. The transverse locking rod member has a first position in which the first movable spring piece is kept disconnected from the first static pole piece after moving toward the first movable spring piece, and a second position in which the first movable spring piece and the first static pole piece can be closed after moving away from the first movable spring piece. 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 second movable spring sheet and the second static pole sheet are kept disconnected after moving toward the main shell plastic part, and a second position in which the second movable spring sheet and the second 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 coupled and contacted, the dry-cooking self-locking push rod will be lifted up, and the transverse locking rod will move toward the end of the first moving spring piece under the thrust of the transverse pushing elastic member, and will be flush with the head end of the first moving spring piece. At this time, the force of the temperature-sensitive bimetallic strip being deformed by high temperature pushes the transmission push rod to move the first moving spring piece downward. When the first moving spring piece moves downward, the transverse locking rod will be pushed by the thrust of the transverse pushing elastic member and move toward the end of the first moving spring piece again until it moves to the limit card. At this time, the first moving spring piece is locked by the transverse locking rod, and the anti-dry-cooking self-locking state is achieved. When the lower coupler assembly and the upper coupler assembly are separated, the dry-cooking self-locking push rod will move downward under the stretching force of the self-locking push rod elastic member, pushing the transverse locking rod to move toward the reverse end of the first moving spring piece until the first moving spring piece bounces up, thereby achieving the unlocking state. 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 second movable spring to operate, so that the contact contacts set 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, 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 top rod is acted upon by the disconnecting top rod elastic member, so that the second moving spring piece 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 not energized at first; 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 housing plastic part of the lower coupler assembly to overcome the force of the disconnecting top rod elastic member, so that the second moving spring piece 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.

[0006] Furthermore, the dry pot self-locking drive assembly includes an inclined block arranged on the dry pot self-locking top rod and an arc block arranged on the transverse locking rod and matched with the inclined block.

[0007] With such arrangement, the self-locking top rod of the dry pot cooperates with the inclined block and the arc block to push the transverse locking rod to move, and the structure is simple and compact.

[0008] Furthermore, the main plastic part is also provided with a dry pot self-locking limit groove and a transverse limit groove, the dry pot self-locking limit groove and the transverse limit groove are vertically arranged, the dry pot self-locking top rod can be slidably arranged in the dry pot self-locking limit groove, and the transverse locking rod can be slidably arranged in the transverse limit groove.

[0013] With such arrangement, the dry pot self-locking top rod can be better aligned with the head end of the first moving reed through the bent portion, so as to improve stability.

[0014] Furthermore, the bending portion is bent toward the lower coupler assembly, and a curved surface is provided on the lower side of the transverse locking rod corresponding to one end of the first movable spring sheet.

[0015] This arrangement allows the self-locking top rod of the dry pot to slide more smoothly.

[0016] Furthermore, a disconnecting push rod limiting groove is vertically arranged on the main body plastic part, and the segmented disconnecting push rod member can be slidably arranged in the disconnecting push rod position groove.
