[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The spiral electric heater offers two technical solutions:

[0025] The first embodiment includes a base 1 and a spiral heating tube 2. The base 1 is provided with a control board and a power socket. The power-on end of the spiral heating tube 2 is inserted into the power socket. The temperature sensor 51 is connected to the control board. The spiral heating tube 2 is installed on the top of the base 1 through a mounting mechanism. The mounting mechanism includes a protective component 3 and multiple mounting components 4.

[0026] The protective component 3 includes multiple fixing seats 31, which are fixed at equal distances to the top of the base 1. A circular rod 32 is fixedly connected between the multiple fixing seats 31. Multiple protective plates 33 are rotatably connected to the surface of the circular rod 32 at equal distances. Multiple mounting components 4 are respectively set inside the multiple protective components 3. The mounting components 4 install and fix the spiral heating tube 2 by clamping. A detachable detection component 5 is provided on one of the protective plates 33.

[0027] The mounting assembly 4 includes two lower clamping blocks 41. The interior of the protective plate 33 has two sets of upper and lower sliding grooves 42. The inner surfaces of the two sets of sliding grooves 42 are slidably connected to the upper clamping blocks 43. The interiors of the lower clamping blocks 41 and the sliding grooves 42 are all provided with slots that are the same as the spiral trajectory of the spiral heating tube 2. The inner side of the protective plate 33 is fixedly connected to two sliders 44. The inner surfaces of the two sliders 44 are slidably connected to sliding rods 45. The upper and lower clamping blocks 43 are fixedly connected to the surfaces of the sliding rods 45. The upper clamping blocks 43 and the two sliders 44 are fixedly connected to a return spring 46. The two return springs 46 are respectively sleeved on the surfaces of the two sliding rods 45. The top of the two sliding rods 45 is fixedly connected to a pressure plate 47. The top of the protective plate 33 is fixedly connected to a mounting base 48. One side of the mounting base 48 is rotatably connected to a rotating rod 49. The other end of the rotating rod 49 is fixedly connected to a cam 410. The cam 410 rotates and pushes the upper clamping blocks 43 to move downward to clamp and fix the spiral heating tube 2.

[0028] When installing the spiral heating tube 2, the installation of the spiral heating tube 2 is quickly completed by rotating the protective plate 33 to a vertical position and cooperating with the installation components 4. Furthermore, the installation components 4 on the multiple protective plates 33 increase the stability of the spiral heating tube 2 after installation, thereby improving the practicality of the device during use.

[0029] The second embodiment differs from the first embodiment in that the detachable detection component 5 includes a temperature sensor 51 and an insertion hole 52 inside the protective plate 33. A retaining ring 53 is fixedly connected to the surface of the temperature sensor 51, and a limit spring 54 is fixedly connected to one side of the retaining ring 53. Two L-shaped grooves 56 are provided on the inner surface of the insertion hole 52. The L-shaped grooves 56 are composed of a horizontal straight part and a vertical arc part. Two mounting blocks 55 that cooperate with the L-shaped grooves 56 are fixedly connected to the surface of the temperature sensor 51.

[0030] A temperature sensor 51 is installed on the protective plate 33 to monitor the internal temperature of the spiral heater 2. The temperature sensor 51 can be quickly installed and removed through the cooperation of the socket 52, L-shaped groove 56 and mounting block 55, which improves the convenience of using the device.

[0031] In use, the spiral heating tube 2 is inserted into the base 1, and the multiple protective plates 33 are rotated so that the multiple protective plates 33 enter the vertical position. At this time, the lower clamping block 41 is below one end of the spiral heating tube 2. Then, the cam 410 is rotated by the rotating rod 49. The cam 410 rotates and contacts the pressure plate 47, thereby pushing the pressure plate 47 to move downward. The pressure plate 47 moves downward and drives the upper clamping block 43 to move downward through the sliding rod 45, thereby clamping and fixing the spiral heating tube 2. In addition, when the temperature sensor 51 needs to be disassembled, the temperature sensor 51 is rotated so that the mounting block 55 is aligned with the horizontal straight part of the L-shaped groove 56. At this time, the temperature sensor 51 can be pulled out.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
