Description

Technical Field

[0001] This utility model relates to the field of graphene rigid heating plate technology, and in particular to an overheat protection structure for graphene rigid heating plate. Background Technology

[0002] Graphene rigid heating plates are mainly composed of graphene and heating wires. Graphene is a novel material with extremely high thermal and electrical conductivity, serving as the core heating element of the heating plate. Graphene rigid heating plates can be used in home heating equipment. However, current graphene heating plates heat up rapidly, and improper temperature control can lead to localized overheating. Prolonged exposure to high temperatures may cause the heating plate material to deform, age, or even burn, affecting its lifespan and performance. Overheating can also damage the circuitry, potentially leading to leakage or short circuits, thus increasing the risk of electric shock. Utility Model Content

[0003] The purpose of this invention is to address the problems mentioned in the background section regarding the rapid heating of existing graphene heating plates, which can lead to localized overheating if the temperature is not properly controlled. Prolonged exposure to high temperatures may cause deformation, aging, or even charring of the heating plate material, affecting its lifespan and performance. Overheating can also damage the circuitry, potentially leading to leakage or short circuits, thus increasing the risk of electric shock.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An overheat protection structure for a graphene rigid heating plate, comprising:

[0006] The electric heating plate body has an upper lifting mechanism installed at its lower end;

[0007] The upper lifting mechanism includes a base plate. An overheat protection component is installed inside the upper lifting mechanism. The overheat protection component includes a fusible alloy wire. A connector is installed at one end of the fusible alloy wire. A plug wire is installed at one end of the connector. A connecting element is sleeved on the outside of the connector. Card holders are installed at both ends of the connector.

[0008] Preferably, the base plate is internally connected to an elastic element, and the upper end of the elastic element is connected to a support plate.

[0009] Preferably, pressure block sleeves are installed at both ends of the connecting component, and reset posts are inserted inside the pressure block sleeves.

[0010] Preferably, a stop plate is installed at one end of the reset post, and a spring is sleeved on the outside of the reset post.

[0011] Preferably, one end of the connecting element is equipped with an electrical wire, and the upper end of the tray is in contact with the lower end of the fusion alloy wire.

[0012] Preferably, the outer surface of the reset post slides into the interior of the pressure block sleeve, and the inner wall of the spring engages with the outer surface of the reset post.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By installing an upper lifting mechanism at the lower end of the heating plate body, the elastic element causes the support plate to fit tightly against the bottom of the heating plate body. An overheat protection component is installed inside the upper lifting mechanism. A plug-in wire connects to the internal wiring of the connecting component, energizing the other end of the fusible alloy wire to the heating plate body, thus energizing and heating the heating plate body. When the heating plate body overheats and burns out the fusible alloy wire, the power is quickly cut off, preventing unnecessary losses. The connector allows the retainer to be inserted into the internal wiring of the connecting component via the semi-circular shape of the abutment plate. Because the upper end of the abutment plate is secured by a reset post and a spring, the abutment plate is locked after the retainer is pushed, quickly limiting the fusible alloy wire. By pulling the reset post, the abutment plate can be opened, and the fusible alloy wire can be removed and replaced with a new one for overheat protection, achieving the desired overheat protection effect.

[0024] Please see Figure 1 - Figure 4 An overheat protection structure for a graphene rigid heating plate, comprising:

[0025] The electric heating plate body 1 has an upper lifting mechanism 2 installed at its lower end.

[0026] The upper lifting mechanism 2 includes a base plate 21. An overheat protection component 3 is installed inside the upper lifting mechanism 2. The overheat protection component 3 includes a fusible alloy wire 31. A connector 32 is installed at one end of the fusible alloy wire 31, and a plug wire 33 is installed at one end of the connector 32. A connecting piece 34 is sleeved on the outside of the connector 32. A retainer 35 is installed at both ends of the connector 32. After the retainer 35 is pushed, the stop plate 38 is locked, thereby quickly limiting the fusible alloy wire 31. When the heating plate body 1 is energized and heats up, when the heating plate body 1 overheats and burns out the fusible alloy wire 31, the power can be quickly cut off to prevent unnecessary losses. By pulling the reset column 37, the stop plate 38 can be opened, and the fusible alloy wire 31 can be disassembled and replaced with a new fusible alloy wire 31 for overheat protection.

[0027] The base plate 21 is internally connected to an elastic element 22, and the upper end of the elastic element 22 is connected to a support plate 23. By installing an upper lifting mechanism 2 at the lower end of the heating plate body 1 and by installing multiple sets of elastic elements 22 at the upper end of the base plate 21, the elastic element 22 elastically drives the support plate 23 to fit tightly against the bottom end of the heating plate body 1.

[0028] Pressure block sleeves 36 are installed at both ends of the connecting component 34. A reset post 37 is inserted inside the pressure block sleeve 36. A stop plate 38 is installed at one end of the reset post 37. A spring 39 is sleeved on the outside of the reset post 37. Since the upper end of the stop plate 38 is connected to the reset post 37 and the spring 39, the stop plate 38 is locked after the card holder 35 is pushed, thereby quickly limiting the fusible alloy wire 31. By pulling the reset post 37, the stop plate 38 can be opened, and the fusible alloy wire 31 can be removed and replaced with a new fusible alloy wire 31 for overheat protection.

[0029] One end of the connecting component 34 is fitted with a wire 4. The upper end of the support plate 23 is in contact with the lower end of the fusible alloy wire 31. The outer surface of the reset post 37 slides in contact with the inside of the pressure block sleeve 36. The inner wall of the spring 39 is in contact with the outer surface of the reset post 37. By installing an overheat protection component 3 inside the upper lifting mechanism 2, by installing a connector 32 at one end of the fusible alloy wire 31, and by installing a plug wire 33 inside the connector 32, the connecting component 34 is sleeved on the outside of the connector 32. The plug wire 33 is connected to the wire 4 inside the connecting component 34 to conduct electricity, so that the other end of the fusible alloy wire 31 is connected to the heating plate body 1, thereby energizing the heating plate body 1. When the heating plate body 1 overheats and burns out the fusible alloy wire 31, the power can be quickly cut off to prevent unnecessary losses.

[0030] Working principle: By installing an upper lifting mechanism 2 at the lower end of the electric heating plate body 1 and installing multiple sets of elastic elements 22 at the upper end of the base plate 21, the elastic elements 22 elastically drive the support plate 23 to fit tightly against the bottom end of the electric heating plate body 1.

[0031] By installing an overheat protection component 3 inside the upper mechanism 2, a connector 32 is installed at one end of the fusible alloy wire 31, and a plug wire 33 is installed inside the connector 32. A connecting component 34 is sleeved on the outside of the connector 32, and the plug wire 33 is connected to the wire 4 inside the connecting component 34 to provide power. This connects the other end of the fusible alloy wire 31 to the heating plate body 1, causing the heating plate body 1 to be energized and heated. When the heating plate body 1 overheats and burns out the fusible alloy wire 31, the power is quickly cut off, preventing unnecessary losses. Pressure block sleeves 36 are installed at both ends of component 34. By installing card holders 35 at both ends of connector 32, the card holders 35 are inserted into the inside of the electrical component 34 through the semi-arc shape of the abutment plate 38 when the connector 32 is inserted. Since the upper end of the abutment plate 38 is connected to the spring 39 via the reset post 37, the abutment plate 38 is locked after the card holder 35 is pushed, thereby quickly limiting the fusible alloy wire 31. By pulling the reset post 37, the abutment plate 38 can be opened, and the fusible alloy wire 31 can be disassembled and replaced with a new fusible alloy wire 31 for overheat protection, thus achieving the effect of overheat protection.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Although this utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
