DETAILED DESCRIPTION

[0022] like Figure 1 A contact heating device for use in a narrow space includes a heating component 1 and a supporting component 2. The heating component 1 includes a base 3, a heating plate 4 is disposed on the base 3, and a temperature transfer contact 5 is mounted on the heating plate 4;

[0023] The support component 2 is composed of a plurality of support rod sections 7 movably connected to form a deformable rod structure.

[0024] In a preferred embodiment, the upper end of the support rod section 7 is provided with a protruding connection ball 8, and the lower end is provided with a spherical connection cavity 9, and the connection ball 8 on the support rod section 7 located below is arranged in the spherical connection cavity 9 on the support rod section 7 located above;

[0025] A gap is formed between the connection positions of two upper and lower adjacent support rod sections 7.

[0026] In a preferred solution, the support rod section 7 is a hollow structure, and a first through hole 10 and a second through hole 11 are respectively provided on the connecting sphere 8 and the spherical connecting cavity 9;

[0027] A heating cable 13 is inserted into the rod structure composed of a plurality of the support rod sections 7 . The heating cable 13 passes through the first through hole 10 , the second through hole 11 and the interior of the support rod section 7 and is connected to the heating plate 4 in the heating component 1 .

[0028] In a preferred embodiment, a semicircular annular groove 12 is provided on the side wall of the heating plate 4, and an air bag 6 is provided on the semicircular annular groove 12;

[0029] An air-filling tube 14 is also provided in the rod structure composed of the plurality of supporting rod sections 7 . One end of the air-filling tube 14 extends into the base 3 and is connected to the inner wall of the annular semicircular groove 12 .

[0030] In a preferred solution, the heating plate 4 is a radial structure composed of a plurality of electric heating plates.

[0031] The above scheme discloses a contact heating device for use in a narrow space:

[0032] The device mainly consists of a heating component 1 and a supporting component 2, and is designed to efficiently transfer heat in a confined environment.

[0033] The heating component 1 includes a stable base 3, on which a heating plate 4 is fixedly mounted. The heating plate 4 is made of high-quality heat-conducting material to ensure that heat is distributed quickly and evenly. The surface of the heating plate 4 is equipped with a temperature transfer contact 5. The temperature transfer contact 5 can be made of a soft and high-temperature resistant material, which can fit closely to the target surface and effectively transfer heat even on irregularly shaped objects. It is particularly suitable for application scenarios that require precise heating.

[0034] The design of the support component 2 is one of the key innovations of the present invention. It is composed of a plurality of movably connected support rod sections 7. Each support rod section is equipped with a protruding connection ball 8 at the upper end, and a spherical connection cavity 9 matching it at the lower end. This design allows adjacent support rod sections to be connected through the nesting of the ball and the cavity, forming a flexible and adjustable rod structure that can adapt to the morphological requirements of various complex spaces. The gap design between the support rod sections not only increases the flexibility of the structure, but also facilitates the passage and maintenance of cables.

[0035] In order to achieve the transmission of electric energy, each support rod section 7 is designed as a hollow structure, and a first through hole 10 and a second through hole 11 are respectively opened on the connecting sphere 8 and the spherical connecting cavity 9. Through these through holes, the heating cable 13 can pass through the entire rod structure and be directly connected to the heating plate 4, ensuring the effective transmission of electric energy while maintaining the flexibility and compactness of the entire device.

[0036] In addition, in order to further improve the adaptability of the device, an annular semicircular groove 12 is designed on the side wall of the heating plate 4, and an air bag 6 is embedded in the groove. By introducing an inflatable tube 14 into the support rod structure and connecting it to the air bag 6 in the annular semicircular groove, the function of fine-tuning the positioning of the heating plate or increasing the contact pressure can be realized when necessary, which is particularly suitable for application scenarios that require dynamic adjustment of the heating contact state.

[0037] In the specific implementation of the heating plate 4, a radial structure consisting of multiple small electric heating plates is adopted. This design not only ensures the uniformity of heating, but also improves the overall thermal efficiency and response speed, so that the heat can be diffused from the center to the surrounding more quickly, meeting the needs of efficient heating in a small space.

[0038] In summary, this embodiment demonstrates an innovative contact heating device, which integrates a flexible support structure, a convenient power and control signal transmission path, and an efficient heating element layout, and is particularly suitable for application environments that have high requirements for heating accuracy and spatial adaptability.
