Description

Technical Field

[0001] The utility model relates to the technical field of vegetable warming pads, in particular to a novel flexible vegetable warming pad. Background Art

[0002] Warming mats are used to keep food warm. Currently, existing warming mats on the market primarily utilize a frame structure to support the entire board. These panels are made of tempered glass, which is thick and heavy, cannot be folded, and takes up a lot of space. They are also relatively complex and costly. Flexible warming mats are also available on the market that can be rolled up and folded, but they require separate strapping. This strapping must be attached to the roll when folding, making it difficult to use and, as a separate accessory, easy to lose. The lack of a handle means that the entire board remains hot during use, requiring the use of tools to clamp and move it. The lack of support on the bottom surface can cause the board to collapse during use, allowing surface water to easily spill onto the tabletop. Therefore, the design of a new flexible warming mat is essential. Summary of the Invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] As shown in Figures 1 to 10, the utility model includes a heating pad 1, a power control box 2 and a heating wire 3. The heating pad 1 is a silicone plate. A silicone handle 11 is provided on one side of the short side of the silicone plate. The silicone handle has multiple uses. It can not only be used as a handle to facilitate the movement of the heating pad, but also can be used as a storage belt for bundling and storage. As shown in Figure 10, it can be rolled up and stored when not in use. When storing, the storage card head 111 is inserted into the storage card hole 12 and clamped in the storage card hole, and is not easy to slip off. Since the storage card head is made of silicone and is elastic, a slight pull on the handle during use can disengage the card head and open it for use.

[0025] A control box connecting end 16 is provided on the other corresponding side of the heating pad. The control box connecting end is C-shaped, as shown in Figure 4. An upward connecting ridge 162 is provided on the edge of the C-shape, and a downwardly protruding connecting ridge 2 161 is provided below the edge of the C-shape. An upper cover slot 211 corresponding to the position of the ridge 1 is provided on the lower end edge of the control box upper cover, and the upper cover slot is plugged into the connecting ridge 162. A lower cover slot 221 corresponding to the position of the ridge 2 is provided on the upper end of the lower cover slot, and the lower cover slot is plugged into the connecting ridge 2 161. A screw through hole 163 is provided on the edge of the ridge for connecting the upper cover and the lower cover. Under the action of the screw, the upper cover and the lower cover are tightly clamped on the control box connecting end of the heating pad. Since the control box connecting end is C-shaped, the C-shape matches the shape of the ridges 1 and ridges 2 on the edges of the connection between the upper cover and the lower cover, so the connection is tight and firm and will not fall off during normal use.

[0026] As shown in Figures 2, 3 and 12, the bottom of the heating pad is provided with a downwardly protruding right-angled support foot 15, and the adjacent rows of support feet are staggered. Since the right-angled support feet are right-angled, the thickness of the two sides of the right angle is the same, and the heating pad panel is not easy to deform after molding. In this embodiment, since 15 rows are provided, each row is provided with dozens of them. When in use, the heating pad panel is flat as a whole, not easy to collapse, and has a good use effect.

[0027] As shown in Figures 4 to 7, the power control box 2 includes an upper cover 21, a lower cover 22, a control circuit board 23, a touch switch 24 and a power jack 25. The inner side of the lower cover is provided with a circuit switch and a time and temperature control circuit board, and the upper side of the upper cover is provided with a touch switch electrically connected to the circuit board.

[0028] As shown in FIG. 11 to FIG. 16 , the edges of the panel of the heating pad are provided with downwardly concave water accumulation grooves 13 , which can store water when a small amount of water overflows and prevent the water from flowing onto the table top.

[0029] The back of the heating plate is provided with multiple interconnected S-shaped heating wire mounting slots 14. As shown in Figure 12, these S-shaped slots are formed by combining multiple S-shaped slots. The S-shaped slots extend from the center of the heating plate toward the sides of the long edges, then wrap around to the connection end of the control box. This allows the heating wire within the slots to be electrically connected to the control circuit board. The uniform layout of the slots ensures uniform heating of the heating wire 3.

[0030] The heater wire mounting slot is provided with downwardly projecting side strips 141 on either side, as shown in Figures 14 and 15. For illustration purposes, the heater wire 3 and sealant 4 are separated in Figure 15 to make the cross-sectional structure easier to see. The height of the sealant side strip exceeds twice the diameter of the heater wire, and is measured from the lowest end of the side strip to the back of the heating pad. The heater wire is located at the bottom of the heater wire mounting slot and secured with sealant. Both ends of the heater wire are electrically connected to the controller's circuit board. The side strips 141 on either side of the heater wire mounting slot 14 provide the required depth, ensuring a more secure installation of the heater wire due to the sealant. Because the side strips are integral with the heating pad, the width of the junction between the side strips and the heating pad is greater than the width of the lower end of the side strip. As shown in the figure, each side strip forms an inverted triangle in cross section. This not only strengthens the connection between the side strips and the heating pad but also improves heat transfer due to the large contact area at the junction.

[0031] The heating pad 1, silicone handle 11, first and second ridges 162 and 161, side strips 141, and rectangular support legs 15 of this utility model are made of silicone and are integrally molded. The heating wire 3 is provided with a flexible insulating layer. The encapsulating adhesive 4 is silicone adhesive, but other adhesives capable of bonding with silicone are not excluded. The adhesive has elastomeric properties after curing and is resistant to temperatures exceeding 200°C. The controller cover 21 and lower cover 22 are made of plastic and have a height of between 12 and 25 mm after installation. The heating pad is between 8 and 12 mm high.

[0032] Regarding the silicone handle 11, the present invention has three embodiments. One is that the silicone handle 11 is connected to the heating pad as one piece; the second embodiment is shown in Figure 16, in which the silicone handle and the heating pad are divided into two parts, and a clamping head 17 is provided at the lower end of the heating pad. The clamping head and the heating pad are connected as one piece. The clamping head is mushroom-shaped, and the head is larger than the inner part. A circular clamping hole is provided at the upper end of the silicone handle, and the clamping hole is smaller than the head of the buckle. The clamping hole is inserted into the clamping head to thereby clamp the silicone handle to the heating pad. Dividing it into two parts is more convenient for the processing of the production mold, the mold is significantly reduced, and the production cost is reduced; the third embodiment is to replace the clamping head of the second embodiment with a rivet, and use the rivet to rivet the silicone handle and the heating pad.

[0033] The power controller part of the utility model includes a power switch, a multi-speed heating time control switch, and a multi-speed 50 to 100 degrees Celsius temperature switch. It can be controlled with one button without complicated adjustments. Since the maximum temperature is set at around 100 degrees Celsius, it is safer to use.
