The spring A serves as a reset button.

[0009] As a further embodiment of this utility model, the two sets of sliders are symmetrically arranged on both sides of the connecting block, and the two sets of plug-in blocks are symmetrically arranged at the bottom of the connecting block. The opposite sides of the two sets of plug-in blocks are provided with inclined surfaces. The inclined surfaces enable the plug-in blocks to be snapped and fixed with the buttons.

[0014] (III) Beneficial Effects

[0015] This utility model provides a modular heating core for an electric heater, which has the following advantages:

[0016] 1. This electric heater features a modular heating core. Through the design of a base, connecting block, locking mechanism, and guiding mechanism, during heating core installation, the sliders on both sides of the connecting block slide downwards along the dovetail groove. Simultaneously, the plug-in block slides downwards along the cross groove. As the plug-in block moves downwards through the inclined opening inside the button, it pushes the button to slide to the right. The button compresses spring A. During the sliding process, the plug-in block contacts the support plate and pushes it downwards. Spring B is compressed downwards by the support plate. When the plug-in block slides to the same horizontal plane as the inclined surface of the inclined opening, the button resets under the action of spring A and engages with the plug-in block. For disassembly, pushing the button causes it to slide to the right away from the plug-in block. Under the force of spring B, the plug-in block pops upwards, completing the rapid disassembly process. This supports free splicing of multiple modules to meet various needs. Furthermore, maintenance only requires single-module operation, saving time and avoiding the destructive operation of traditional overall disassembly.

[0017] 2. This modular heating core of the electric heater, through the setting of the heating shell and safety mechanism, when the heating core causes local overheating due to abnormal operating conditions (such as heat dissipation failure or power overload) during the operation of the electric heater, the protection device inside the heating shell quickly cuts off the power supply. At the same time, the molecular structure or crystal arrangement of the thermosensitive material built into the sensing strip undergoes an irreversible change, and the surface color of the sensing strip permanently changes from the initial color (such as gray) to the warning color (such as red). Moreover, the color change reaction does not require an external power supply or complex reading equipment and can be directly identified by visual inspection, which facilitates subsequent inspection and maintenance. This effectively makes up for the shortcomings of traditional electronic temperature control systems in high-temperature scenarios of electric heaters. It is suitable for the safety protection and efficient operation and maintenance of modular heating cores, reducing equipment complexity and maintenance costs. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a modular heating core for an electric heater, including a base 1 and a connecting block 2. Several sets of cross grooves are symmetrically opened on both sides of the base 1. A locking mechanism 3 is slidably connected inside the sets of cross grooves. Side plates 4 are provided on both sides of the base 1. A guide mechanism 5 is opened on one side of the side plate 4. A heating shell 6 is fixedly connected above the connecting block 2. A safety mechanism 7 is provided inside the heating shell 6. The locking mechanism 3 includes a button 301 slidably connected inside the cross groove. An inclined opening 302 is opened inside the button 301. A spring A 303 is fixedly connected to one side of the button 301. A spring B 304 is fixedly connected to the inner bottom wall of the cross groove. A load-bearing plate 305 is fixedly connected to the top of the spring B 304. The guide mechanism 5 includes a dovetail groove opened on one side of the side plate 4. A slider 501 is slidably connected inside the dovetail groove. Two sets of plug-in blocks 502 are provided at the bottom of the connecting block 2. The safety mechanism 7 includes a sensing strip 701 provided on one side of the heating shell 6. A protective device 702 is provided on the surface of the heating shell 6.

[0025] Spring A303 is fixedly connected to the inner wall of the sliding groove. The length of the inclined opening 302 is greater than the width of the plug block 502. The plug block 502 is located directly above the support plate 305. Through the setting of spring A303, it plays the role of reset button 301.

[0026] Two sets of sliders 501 are symmetrically arranged on both sides of the connecting block 2, and two sets of plug-in blocks 502 are symmetrically arranged at the bottom of the connecting block 2. The opposite sides of the two sets of plug-in blocks 502 are provided with inclined surfaces 8. The inclined surfaces 8 are provided to allow the plug-in blocks 502 to be snapped and fixed with the button 301.

[0027] The heating shell 6 has a heating wire 9 inside and a power interface 10 on its surface. The heating wire 9 is electrically connected to one side of the power interface 10 via a power cord. The power interface 10 serves to connect the heating wire to the outside circuit.

[0028] The surface of the heating shell 6 is uniformly provided with heat dissipation fins 11, and a circuit board 12 is threadedly connected to one side of the heating shell 6. The heat dissipation fins 11 are used to increase the heat dissipation area and improve the heat dissipation efficiency.

[0029] A temperature module 13 is provided on one side of the circuit board 12, and a temperature sensor 14 is provided on the other side of the circuit board 12. The temperature sensor 14 is used to control the temperature.

[0030] The base 1 has mounting plates 15 on both sides. The surface of the mounting plates 15 has several sets of mounting holes. The mounting plates 15 serve to fix the base in place.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When installing the heating core, slide the sliders 501 on both sides of the connecting block 2 downward along the dovetail groove. At this time, the plug block 502 slides downward along the cross groove. When the plug block 502 moves downward through the inclined opening 302 inside the button 301, the plug block 502 pushes the button 301 to slide to the right. The button 301 compresses the spring A303. During the sliding process, the plug block 502 will contact the support plate 305 and push the support plate 305 downward. The spring B304 is pressed downward by the support plate 305. When the plug block 502 slides to the inclined surface 8 and the inclined surface 8 of the inclined opening 302 are at the same level, the button 301 is reset under the action of the spring A303 and is locked in place with the plug block 502. When disassembly is required, push the button 301. The button 301 slides to the right away from the inside of the plug block 502. Under the action of the spring B304, the plug block 502 pops upward, completing the quick disassembly process.

[0033] The second step: When the electric heater is working, if the heating core overheats locally due to abnormal conditions (such as heat dissipation failure or power overload), the protection device 702 inside the heating shell 6 quickly cuts off the power supply. At the same time, the molecular structure or crystal arrangement of the thermosensitive material built into the sensing strip 701 undergoes an irreversible change. The surface color of the sensing strip 701 permanently changes from the initial color (such as gray) to the warning color (such as red). Moreover, the color change reaction does not require an external power supply or complex reading equipment and can be directly identified by visual inspection.
