[0023] The following refers to the Fig. 1 to 5 to describe a food warming plate according to the embodiment of the present utility model.

[0024] The food warming plate according to the exemplary embodiment of the present utility model comprises a heating base 100 and a cover strip 200. The heating base is designed to accommodate external dishes. A groove 12 is provided at a bottom of the heating base 100, and a heating wire 140 is provided in the groove 12. The cover strip 200 is provided at an exit point of the groove 12 and seals the heating wire 140 in the groove 12. The heating wire 140 is bonded to the cover strip 200 and a side wall of the groove 12 by an adhesive.

[0025] As in the Fig. 3 and Fig. For example, as shown in Figure 5, the groove 12 is provided circumferentially at the bottom of the heating pad 100, and the heating wire 140 is laid along the direction of the groove 12, so that the entire heating pad is heated more evenly. The cover strip 200 is provided at the exit point of the groove 12 and seals the heating wire 140 in the groove 12. The adhesive is filled between the cover strip 200 and an inner wall of the groove 12 to form a complete sealing layer.

[0026] With this configuration, the food warming plate according to the embodiment of the present invention can achieve at least the following advantageous effect: By combining the groove 12 with the cover strip 200, the adhesive is packed between the groove 12 and the cover strip 200 to form a closed space, thereby preventing the adhesive from directly contacting the external environment. Weathering and dry cracking of the adhesive caused by air, moisture, and other factors are effectively prevented, and the service life of the food warming plate is extended. The cover strip 200 closes off the exit of the groove 12 to prevent insects, dust, and other foreign matter from entering the groove 12 and sticking to the adhesive, and to reduce the difficulty of cleaning and keep the internal environment of the food warming plate clean.The groove 12 provides a secure mounting position for the heating wire 140, preventing it from shifting or detaching during use. Dual fixation by the cover strip 200 and the adhesive simultaneously prevents the heating wire 140 from being compressed or worn by external forces, ensuring the stability and safety of the heating function. This design enables the installation and replacement of the heating wire 140. When repairing or replacing the heating wire 140, only the cover strip 200 can be easily removed, enabling handling for repair or replacement, reducing maintenance costs and complexity.

[0027] In some specific embodiments of the present utility model, the groove 12 comprises a receiving groove 120 for placing the heating wire 140 and a mounting groove for placing the cover strip 200. The mounting groove is provided at an opening point of the receiving groove 120 and the receiving groove 120 is connected to the mounting groove.

[0028] As in the Fig. 4 and Fig. 5, the groove 12 includes a receiving groove 120 for placing the heating wire 140 and a mounting groove for placing the cover strip 200. The receiving groove 120 is connected to the mounting groove, and a width of a sectional surface of the receiving groove is larger than a width of a sectional surface of the groove 12. The cover strip 200 is embedded in the mounting groove, and a vertical portion of the cover strip covers the opening of the groove 12, and an inverted T-shaped sealing structure is formed by the receiving groove 120 and the mounting groove.

[0029] The width difference between the mounting groove and the receiving groove 120 forms a stepped structure. After the cover strip 200 is embedded, the adhesive forms a double sealing surface at the step. The widening of the mounting groove allows the cover strip 200 to slide in transversely. During repairs, only the cover strip 200 can be pulled out along the direction of the groove without destroying the adhesive.

[0030] In some specific embodiments of the present invention, the cover strip 200 is embedded in the mounting groove to seal the heating wire 140 in the receiving groove 120. A width of a sectional surface of the mounting groove is greater than the width of the sectional surface of the receiving groove 120.

[0031] For example, in the Fig. 4 and Fig. As shown in Figure 5, the cover strip 200 is embedded in the mounting groove to seal the heating wire 140 into the receiving groove 120, and the width of the cutting surface of the mounting groove is larger than the width of the cutting surface of the receiving groove 120. The width difference between the mounting groove and the receiving groove 120 forms a stepped structure. The widening of the mounting groove allows the cover strip 200 to slide in transversely. During repair, only the cover strip 200 can be pulled out along the direction of the groove without destroying the adhesive.

[0032] In some specific embodiments of the present utility model, the mounting groove includes an exit portion 121 and a mounting portion 122 along a thickness direction of the heating pad 100. The width of the sectional surface of the mounting portion 122 is larger than the width of the sectional surface of the exit portion 121, and the cover strip 200 is provided entering the mounting portion 122 from the exit portion 121 and embedded in the mounting portion 122.

[0033] For example, in Fig. As shown in Figure 5, the mounting groove is divided into the output portion 121 and the mounting portion 122 along the thickness direction of the heating pad 100. The width of the sectional surface of the mounting portion 122 is larger than the width of the sectional surface of the output portion 121, and the cover strip 200, after being inserted over the output portion 121, is clamped into the mounting portion 122, forming a stepped embedded structure.

[0034] In some specific embodiments of the present utility model, an arcuate transition surface is provided at a connection point of the mounting portion 122 with the output portion 121, wherein the cover strip 200 abuts against the arcuate transition surface.

[0035] For example, in Fig. 5, an arcuate transition surface is provided at the connection point of the mounting section 122 with the output section 121, wherein an adapted arcuate contour is provided at a corresponding point of the cover strip 200, which lies sealingly against the transition surface when inserted.

[0036] The arcuate transition surface avoids the stress concentration caused by the rectangular structure, and the arcuate surface reduces the insertion resistance of the cover strip 200, making the assembly process smoother while avoiding hard friction.

[0037] In some specific embodiments of the present utility model, the width of the cross-sectional area of ​​the output section 121 is 2.5 millimeters, the width of the cross-sectional area of ​​the mounting section 122 is 3-3.5 millimeters, the width of the cross-sectional area of ​​the groove 12 is 2 millimeters, and the width of the cross-sectional area of ​​the receiving groove 120 is not less than a diameter of the heating wire. Preferably, the diameter of the heating wire is 2 millimeters. The above-mentioned size values ​​are preferred embodiments for this embodiment, but should not be limited thereto. As long as the diameter of the heating wire is smaller than the width of the cross-sectional area of ​​the output section 121 and also smaller than the width of the cross-sectional area of ​​the mounting section 122, this falls within the scope of this application.

[0038] The width of the cross-sectional area of ​​the receiving groove 120 is not smaller than the diameter of the heating wire, so that the heating wire 140 is conveniently placed in the receiving groove 120.

[0039] In some specific embodiments of the present invention, the heating pad 100 is made of a flexible material. The cover strip 200 is also made of a flexible material.

[0040] In some specific embodiments of the present utility model, a power supply 300 is further provided, wherein both ends of the heating wire 140 are each electrically connected to the power supply 300, thereby forming a closed circuit.

[0041] For example, in the Fig. 1 and Fig. As shown in Figure 3, the power supply 300 is connected to both ends of the heating wire 140 via a wire, forming a closed circuit. A built-in temperature control element is provided in the power supply 300 to heat the heating wire 140 and control the temperature.

[0042] In some specific embodiments of the present utility model, a plurality of protrusion structures 130 are provided on the bottom of the heating pad 100.

[0043] For example, in Fig.As shown in Figure 2, protrusion structures 130 are evenly distributed on the bottom of the heating pad 100. The protrusion structures 130 support the entire food warming plate, so that a certain gap exists between the heating pad 100 and the table, and a certain airflow can be maintained, thereby dissipating heat and preventing the heating pad 100 from burning the table.
