[0029] The following is for reference. Figures 1 to 5 This describes a food warmer according to an embodiment of the present invention.

[0030] According to an embodiment of the present invention, a food warmer includes a heating pad 100 and a shielding strip 200. The heating pad is used to hold external tableware. The bottom of the heating pad 100 has a groove 12, in which a heating wire 140 is disposed. The shielding strip 200 is disposed at the outlet of the groove 12, enclosing the heating wire 140 in the groove 12. The heating wire 140 is bonded to the shielding strip 200 and the side wall of the groove 12 by adhesive.

[0031] For example Figure 3 and Figure 5 As shown, the groove 12 meanders along the bottom of the heating pad 100, and the heating wire 140 is laid along the direction of the groove 12 to make the heating pad heat up more evenly. The shielding strip 200 is set at the outlet of the groove 12 to seal the heating wire 140 in the groove 12. Adhesive fills the space between the shielding strip 200 and the inner wall of the groove 12 to form a complete sealing layer.

[0032] According to the embodiments of this utility model, the food warmer board, through its design, achieves at least the following beneficial effects: The combined design of the groove 12 and the shielding strip 200 encapsulates the adhesive between the groove 12 and the shielding strip 200, forming a closed space. This prevents the adhesive from being directly exposed to the external environment, effectively preventing weathering and cracking of the adhesive due to air, moisture, and other factors, thus extending the service life of the food warmer board. The shielding strip 200 seals the outlet of the groove 12, preventing insects, dust, and other foreign objects from entering the groove 12 and sticking to the adhesive, reducing cleaning difficulty and keeping the internal environment of the food warmer board clean. The groove 12 provides a stable installation position for the heating wire 140, preventing the heating wire 140 from shifting or loosening during use. Simultaneously, the double fixation of the shielding strip 200 and the adhesive prevents the heating wire 140 from being subjected to external pressure or wear, ensuring the stability and safety of the heating function. The structural design facilitates the installation and replacement of the heating wire 140. When the heating wire 140 needs to be repaired or replaced, it can be operated simply by removing the shielding strip 200, which reduces maintenance costs and difficulty.

[0033] In some specific embodiments of this utility model, the groove 12 includes a receiving groove 120 for placing the heating wire 140 and a mounting groove for placing the shielding strip 200. The mounting groove is disposed at the opening of the receiving groove 120; and the receiving groove 120 is connected to the mounting groove.

[0034] For example Figure 4 and Figure 5As shown, the groove 12 includes a receiving groove 120 for placing the heating wire 140 and a mounting groove for placing the shielding strip 200. The receiving groove 120 and the mounting groove are connected, and its cross-sectional width is greater than that of the groove 12. The shielding strip 200 is embedded in the mounting groove, and its longitudinal portion covers the opening of the groove 12, forming an inverted "convex" shaped sealing structure between the receiving groove 120 and the mounting groove.

[0035] The width difference between the mounting groove and the receiving groove 120 forms a stepped structure. After the shielding strip 200 is embedded, the adhesive forms a double sealing surface at the step. The widened design of the mounting groove allows the shielding strip 200 to slide in and be fixed laterally. During maintenance, the shielding strip 200 only needs to be pulled out along the groove direction without damaging the adhesive.

[0036] In some specific embodiments of this utility model, the shielding strip 200 is embedded in the mounting groove to enclose the heating wire 140 in the receiving groove 120; and the cross-sectional width of the mounting groove is greater than the cross-sectional width of the receiving groove 120.

[0037] For example Figure 4 and Figure 5 As shown, the shielding strip 200 is embedded in the mounting groove, enclosing the heating wire 140 in the receiving groove 120; and the cross-sectional width of the mounting groove is greater than the cross-sectional width of the receiving groove 120. The width difference between the mounting groove and the receiving groove 120 forms a stepped structure. The widening design of the mounting groove allows the shielding strip 200 to slide in and be fixed laterally. During maintenance, the shielding strip 200 only needs to be pulled out along the direction of the groove without damaging the adhesive.

[0038] In some specific embodiments of this utility model, the mounting groove includes an outlet section 121 and a mounting section 122 along the thickness direction of the heating pad 100. The cross-sectional width of the mounting section 122 is greater than the cross-sectional width of the outlet section 121. The shielding strip 200 enters the mounting section 122 from the outlet section 121 and is embedded in the mounting section 122.

[0039] For example Figure 5 As shown, the mounting groove is divided into an outlet section 121 and an installation section 122 along the thickness direction of the heating pad 100. The cross-sectional width of the installation section 122 is greater than that of the outlet section 121. The shielding strip 200 is inserted from the outlet section 121 and then snapped into the installation section 122 to form a stepped interlocking structure.

[0040] In some specific embodiments of this utility model, an arc-shaped transition surface is provided at the connection between the installation section 122 and the outlet section 121, and the shielding strip 200 abuts against the arc-shaped transition surface.

[0041] For example Figure 5 As shown, an arc-shaped transition surface is provided at the connection between the installation section 122 and the outlet section 121, and the corresponding position of the shielding strip 200 adopts a matching arc-shaped contour, which fits tightly with the transition surface when inserted.

[0042] The curved transition surface avoids stress concentration caused by right-angle structures. The curved surface reduces the insertion resistance of the shielding strip 200, making the installation process smoother and avoiding hard friction.

[0043] In some specific embodiments of this utility model, the cross-sectional width of the outlet section 121 is 2.5 mm, the cross-sectional width of the mounting section 122 is 3-3.5 mm, the cross-sectional width of the groove 12 is 2 mm, and the cross-sectional width of the receiving groove 120 is not less than the diameter of the heating wire, preferably the diameter of the heating wire is 2 mm. The above-mentioned dimensions are preferred solutions of this embodiment, but should not be limited thereto. As long as the diameter of the heating wire is less than the cross-sectional width of the outlet section 121 and less than the cross-sectional width of the mounting section 122, it should be understood as falling within the protection scope of this application.

[0044] The cross-sectional width of the receiving groove 120 is not less than the diameter of the heating wire, so that the heating wire 140 can be placed in the receiving groove 120.

[0045] In some specific embodiments of this utility model, the heating pad 100 is made of a flexible material; the shielding strip 200 is also made of a flexible material. The flexible material can be soft rubber, TPE / TPR, PU / PVC, natural rubber, etc., but is not limited to these. Other common flexible materials should also fall within the protection scope of this patent. The heating pad 100 is made of a flexible material, so that the food warming board can be rolled up or folded up, making it convenient to store the food warming board.

[0046] In some specific embodiments of this utility model, a power supply 300 is also included, and both ends of the heating wire 140 are electrically connected to the power supply 300 to form a closed circuit.

[0047] For example Figure 1 and Figure 3 As shown, the power supply 300 is connected to both ends of the heating wire 140 via wires to form a closed circuit. The power supply 300 has a built-in temperature control element to heat and control the temperature of the heating wire 140.

[0048] In some specific embodiments of this utility model, the bottom of the heating pad 100 is provided with a plurality of raised structures 130.

[0049] For example Figure 2 As shown, the bottom of the heating pad 100 has evenly distributed raised structures 130, which support the entire food warming board and create a certain gap between the heating pad 100 and the tabletop, allowing for air circulation, heat dissipation, and preventing the heating pad 100 from burning the tabletop.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
