DETAILED DESCRIPTION

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] This embodiment provides a heating cup, such as Figure 1-4As shown, it includes a cup body 100, in which an inner liner 200 is provided. The bottom of the inner liner 200 is provided with a heating element 300 that abuts against the inner liner 200. The heating element 300 can generate heat and heat the inner liner 200 when powered. The lower end of the cup body 100 has a mounting cavity 110, which is located below the inner liner 200. The inner side wall of the mounting cavity 110 has a first fixing portion 111. A fixing bracket 400 is installed in the mounting cavity 110, and the fixing bracket 400 has a second fixing portion 410. A flexible fixing member 500 is provided between the fixing bracket 400 and the heating element 300. The first fixing portion 111 and the second fixing portion 410 are detachably fixed so that the fixing bracket 400 can tightly abut the flexible fixing member 500 against the heating element 300.

[0024] like Figure 2 、 3 As shown, the first fixing portion 111 and the second fixing portion 410 are both threaded structures. After the fixing bracket 400 is locked on the cup body 100, it has an upward thrust on the flexible fixing member 500, so that the flexible fixing member 500 presses the heating element tightly against the lower surface of the bottom of the inner liner 200. The flexible fixing member 500 avoids unnecessary damage to the surface of the heating element 300 during the extrusion process, and at the same time improves the adaptability of the pressing strength to the uneven surface details of the heating element 300, so that the heating element 300 can be better fitted to the inner liner 200, thereby improving the heating efficiency. The flexible fixing member 500 of this embodiment uses high-temperature resistant silicone. In other optional embodiments, the first fixing portion 111 and the second fixing portion 410 can also be a clamping structure, and a guide slope is provided on the clamping structure so that the fixing bracket 400 can squeeze the flexible fixing member 500 during the clamping process.

[0025] The heating element 300 is a heating film. It can be made of a high-temperature-resistant PI heating film. The heating film is adhered to the lower surface of the bottom of the liner 200 using adhesive. The back of the heating film is adhered with high-temperature-resistant adhesive, allowing for direct initial positioning and attachment to the lower surface of the bottom of the liner 200, simplifying installation.

[0026] like Figure 3 、 4 As shown, the heating film includes a ring-shaped heating area 310 and a non-heating area 320 located in the middle of the heating film. The lead wire 330 of the heating film extends downward from the non-heating area 320. A temperature sensor is installed in the non-heating area 320, and the distance between the temperature sensor and the heating area 310 is greater than or equal to 2mm. This ensures that the temperature sensed by the temperature sensor is less directly affected by the heating area 310, thereby more accurately measuring the actual temperature of the metal material at the bottom of the inner liner 200.

[0027] like Figure 1 、 3 As shown, the middle portion of the flexible fixing member 500 has a first through hole 510, and the upper end of the flexible fixing member 500 has an extrusion surface, which abuts against the heating member 300 and completely covers the heating area 310, ensuring that the flexible fixing member 500 can fully squeeze the heating area 310 and better exert the heating effect of the heating area 310.

[0028] Furthermore, the fixing bracket 400 has a second through hole 420 in the middle, and the cross-sectional area of ​​the second through hole 420 is larger than the area of ​​the non-heating area 320. This prevents the high-temperature-resistant fixing bracket 400 from interfering with the wiring harness solder points and temperature sensors in the non-heating area 320 and causing the risk of extrusion damage.

[0029] like Figure 3 、 4 As shown, the fixing bracket 400 has an operating cavity with an opening facing downward, and an operating rib 430 is provided on the inner wall of the operating cavity. The fixing bracket 400 can be screwed by operating the operating rib 430 with a finger, which facilitates the disassembly and assembly of the fixing bracket 400.

[0030] like Figure 1 As shown, the upper surface of the fixing bracket 400 and the lower surface of the flexible fixing member 500 have concave-convex structures 440 that fit into each other. This facilitates the lateral positioning of the flexible fixing member 500, prevents lateral misalignment or displacement of the flexible fixing member 500, and improves installation stability. In other optional embodiments, the upper surface of the fixing bracket 400 and the lower surface of the flexible fixing member 500 can also be in flat contact.

[0031] like Figure 1 As shown, a vacuum chamber 120 is provided between the cup body 100 and the inner liner 200. This prevents excessive heat transfer from the inner wall of the cup body 100 to the outer wall of the cup body 100 after heating, thereby reducing the risk of burns to the user's hands during use. In other optional embodiments, the vacuum chamber 120 may also be provided on the inner liner 200 or the cup body 100.
