[0024] Reference Figure 1-4 The low-resistance ceramic heating device of this utility model includes: a shell 1, a guide groove 2 provided on the inner wall of the shell 1, a placement rack 3 provided on the inner wall of the shell 1, a limit post 4 fixedly connected to the upper end of the placement rack 3, a heating unit 5 provided between the placement rack 3 and the shell 1, an installation unit 6 provided on the upper end of the shell 1, a shell cover 7 provided on the upper end of the shell 1, and a fixing groove 8 provided on the outer side wall of the shell cover 7.

[0025] The heating unit 5 includes a heating tube 501 installed between the placement frame 3 and the housing 1. An electric heating wire 502 is provided on the inner wall of the heating tube 501. Two fixing brackets 503 are fixedly connected to the outer wall of the heating tube 501, and the side of the two fixing brackets 503 away from the heating tube 501 is fixedly connected to the inner wall of the housing 1. The heating unit 5 can heat objects inside the housing 1.

[0026] The mounting unit 6 includes a mounting base 601 fixedly connected to the upper end of the housing 1. A sliding cavity 602 is provided inside the side wall of the mounting base 601. A sliding plate 603 is slidably connected to the inner wall of the sliding cavity 602. A mounting post 604 is fixedly connected to one side of the sliding plate 603. A sliding rod 605 is fixedly connected to the side of the sliding plate 603 away from the mounting post 604. A handle 607 is fixedly connected to one end of the sliding rod 605 that passes through the mounting base 601. The mounting unit 6 can limit the cover 7 to the upper end of the housing 1.

[0027] Mounting post 604 extends through one side of mounting base 601 and is slidably connected thereto. Mounting post 604 is also slidably connected to the inner wall of fixing groove 8. Mounting post 604 prevents displacement of cover 7.

[0028] The limiting post 4 is adapted to the inner wall of the guide groove 2, and the limiting post 4 is slidably connected to the guide groove 2. The limiting post 4 helps to ensure that the placement rack 3 can be stably placed or pulled out of the housing 1.

[0029] The heating element 501 is spiral-shaped and made of aluminum nitride ceramic material. The spiral shape of the heating element 501 enables heat to be evenly distributed in the housing 1, while also helping to increase the heating area and improve heating efficiency.

[0030] A power supply assembly 101 is mounted on the outer wall of the housing 1, and the power supply assembly 101 is electrically connected to the heating wire 502. The power supply assembly 101 provides electrical energy to the heating wire 502.

[0031] A sealing gasket 701 is installed at the lower end of the cover 7, and a vent hole 702 is provided at the upper end of the cover 7. The sealing gasket 701 ensures the airtightness of the connection between the cover 7 and the housing 1, and the vent hole 702 prevents excessive internal pressure in the housing 1 from causing safety hazards.

[0032] Working principle: During use, the object to be heated is placed in the placement rack 3. The power supply component 101 provides power to the heating wire 502, causing the heating wire to heat up and transfer the heat to the heating tube 501. The heating tube 501 can transfer the heat to the surrounding environment or the object to be heated. During the heating process, the placement rack 3 can separate the object from the heating tube 501 to prevent the object from directly touching the heating tube 501. In addition, the placement rack 3 can be pulled out from the housing 1 for easy placement or removal of the object. In addition, during the heating process, the handle 606 is pulled to retract the mounting post 604 at one end of the sliding plate 603 into the sliding cavity 602. The cover 7 is then placed on the upper end of the housing 1. At this time, the handle 606 is released, and the sliding plate 603 is affected by the rebound force of the spring 606, causing the mounting post 604 to slide into the fixing groove 8, thereby fixing the cover 7 and preventing the cover 7 from being accidentally opened during the heating process.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
