Description

Technical Field

[0001] The invention relates to the technical field of heating devices, and in particular to a foldable and storable towel heating device. Background Art

[0002] A towel warmer is a device used to heat towels or clothing. A towel warmer is primarily used to heat towels to keep them warm and increase comfort during use, especially in cold weather. In addition to towels, it can also be used to heat other items such as blankets, bathrobes, and pajamas.

[0003] In the current business environment, transportation costs have become a major expense. In the first and last leg of product transportation, the smaller the volume, the lower the transportation cost. The folding storage type greatly reduces the product packaging volume. In order to reduce transportation costs, the existing towel heating devices on the market are mostly folding products. Their defects are obvious. They mainly use soft cloth as the surface. This method has the following disadvantages:

[0004] 1. Due to the limitation of flexible materials, the temperature is relatively low (about 80°C), which cannot reach the temperature of a regular towel barrel (130°C), resulting in a very poor user experience.

[0005] 2. In terms of safety, the heating wire is distributed inside the soft cloth. Compared with our overall plastic hard shell, the safety factor is lower and the use effect is not ideal. Summary of the invention

At the same time, the locking rod 174 drives the hook 1741 to disengage from the rear locking plate 155 and the front locking plate 115, so that the combined rear shell 15, the combined left side plate 13, the combined right side plate 14, and the combined front shell 11 can be disassembled in turn. One end of the central rotating shaft 173 is in the shape of an inner hexagon, and the central rotating shaft 173 can be rotated by a inner hexagon screwdriver.

[0058] As a specific technical solution of this embodiment, the combined cover 16 includes a cover body 161, the bottom of the cover body 161 is movably connected with a scented sheet box 162, the top of the cover body 161 is provided with a leather handle 163 and a handle head cover 164 located at both ends of the leather handle 163, the top of the combined front shell 11, the combined rear shell 15, the combined left side plate 13 and the combined right side plate 14 are jointly provided with a cover groove 19, and the cover body 161 is movably placed inside the cover groove 19.

[0059] In this embodiment, after the combined front shell 11, the combined rear shell 15, the combined left side plate 13 and the combined right side plate 14 are assembled, they can be plugged in to make the front heating plate 112, the left heating plate 132, the right heating plate 142 and the rear heating plate 152 generate heat. Towels and other products that need to be heated and dried can be placed inside the device body 1 through a shelf for heating and drying. The combined cover 16 is covered inside the cover groove 19 to ensure the heating and drying efficiency.

[0060] When using, refer to Fig. 9When the user receives the disassembled device body 1, refer to Figure 8 , Figure 7 and Figure 6 First, remove the combined rear shell 15, the combined left side plate 13 and the combined right side plate 14, refer to Figure 5 , Figure 4 , Figure 3 and Figure 2 , turn over the combined base 12, first assemble the combined left side plate 13 or the combined right side plate 14, after the combined left side plate 13 and the combined right side plate 14 are assembled, assemble the combined rear shell 15, after the combined rear shell 15 is assembled, the limit block 158 triggers the limit switch 125, and the circuit conduction of the PCB main board 123 is controlled by the limit switch 125, see Fig. 20 After the device body 1 is stood up, it can be plugged in for use. The combined rear shell 15, the combined left side plate 13, the combined right side plate 14, and the combined front shell 11 can be unlocked by rotating the central shaft 173. After disassembly, the combined base 12 is turned over and stored on one side of the combined front shell 11, and the combined cover 16, the combined left side plate 13 and the combined right side plate 14 are stacked in sequence. Finally, the combined rear shell 15 and the combined front shell 11 are assembled together for packaging and transportation.

[0061] In summary, the foldable towel heating device, the combined front shell 11, the combined base 12, the combined left plate 13, the combined right plate 14, the combined rear shell 15 and the combined cover 16 can be disassembled and folded, which greatly reduces the space occupied by transportation and reduces the transportation cost. The stability of the device body 1 after assembly is ensured by plugging multiple posts and fixing seats in conjunction with the locking mechanism 17. The conductive terminals 18 are plugged in between the components for conductivity, which does not affect disassembly. The limit switch 125 is triggered by the limit block 158, so that the device body 1 cannot be turned on and work if it is not fully assembled, which makes it safer to use. The entire device body 1 adopts a hard shell that is foldable, and the heating temperature and safety are better than those of conventional folding towel heating products, meeting the user's needs.
