Detailed Implementation

[0023] This utility model provides, for example Figures 1-6 The high-strength PTC electric heater resistant to seawater corrosion shown includes an electric heater body 1, a base 2 and a support plate 3. The support plate 3 is fixedly connected to the bottom of the electric heater body 1 and is located above the base 2.

[0024] The electric heater body 1 is a PTC electric heater, which includes a heat pipe, a heating core and other structures. It features automatic temperature control, energy saving and long natural life.

[0025] The base 2 is provided with an anti-corrosion coating 19. The anti-corrosion coating 19 can be, but is not limited to, water-based acid and alkali resistant high-temperature anti-corrosion paint, which has anti-corrosion properties. Especially when the PTC electric heater is used in marine vessels, the base 2 is placed on the ground of the vessel and is easily affected by marine water vapor. In actual use, the anti-corrosion coating 19 can also be provided on the support plate 3 and other structures.

[0026] To facilitate the adjustment of the height of the electric heater body 1, a rotating groove 4 is provided on the upper surface of the base 2. A threaded rod 5 is rotatably connected inside the rotating groove 4. A threaded hole that mates with the threaded rod 5 is provided on the support plate 3. The base 2 has a certain weight so that it is not easy to slide freely when the ship is rocking.

[0027] A guide frame 18 is fixedly connected to the upper surface of the base 2, and a through hole is provided on the support plate 3 to cooperate with the guide frame 18.

[0028] Rotating the threaded rod 5 causes the guide frame 18 to limit the movement of the support plate 3, which in turn moves the electric heater body 1 up and down, adjusting the height of the electric heater body 1 and improving the flexibility of use. At the same time, the threaded rod 5 and the guide frame 18 can be used as a hanging rack, making it convenient for users to hang shoes, socks, etc. for drying. Furthermore, the base 2, support plate 3, guide frame 18, and other structures are protected on the outside of the electric heater body 1, which can improve the strength of the PTC electric heater.

[0029] To fix the position of the base 2, a circular groove 6 is provided at the bottom of the base 2. A suction cup 7 is fixedly connected to the lower half of the circular groove 6, and an air cylinder 8 is fixedly connected to the upper half of the circular groove 6. The air cylinder 8 is connected to the suction cup 7, and a slider 9 is slidably installed inside the air cylinder 8. A square groove 11 is provided inside the base 2, located above the air cylinder 8. An electric push rod 10 is fixedly connected to the top of the base 2. The telescopic end of the electric push rod 10 extends into the interior of the square groove 11, and a through hole is provided at the top of the air cylinder 8 for the telescopic end of the electric push rod 10 to pass through. The slider 9 is fixedly connected to the telescopic end of the electric push rod 10.

[0030] After placing the base 2 on the ground, the suction cup 7 adheres to the ground. Activate the electric push rod 10 and control the extension end of the electric push rod 10 to retract, causing the slider 9 to move upward inside the air cylinder 8, so that the inside of the suction cup 7 is in a negative pressure state, and the base 2 is fixed to the ground, improving the stability of the PTC electric heater.

[0031] Before placing the base 2, the operator can clean the ground to ensure smoothness, making it easier for the suction cup 7 to adhere to the ground.

[0032] A circular hole 13 is provided at the top of the square groove 11, which communicates with the rotating groove 4. A circular plate 14 is fixedly connected inside the circular hole 13. An elastic telescopic rod 16 is slidably mounted on the circular plate 14, and a pressure plate 15 is fixedly connected to the bottom end of the elastic telescopic rod 16. A spring 17 is fitted on the outside of the elastic telescopic rod 16. One end of the spring 17 is fixedly connected to the lower surface of the circular plate 14, and the other end of the spring 17 is fixedly connected to the upper surface of the pressure plate 15. A square plate 12 is fixedly connected to the telescopic end of the electric push rod 10, and the square plate 12 abuts against the pressure plate 15.

[0033] Specifically, when the electric push rod 10 drives the slider 9 to move upward inside the air cylinder 8, the square plate 12 moves upward synchronously, first abutting against the bottom of the pressure plate 15, and then the pressure plate 15 drives the elastic telescopic rod 16 to move upward. The telescopic end of the elastic telescopic rod 16 abuts against the bottom end of the threaded rod 5, and the telescopic end of the elastic telescopic rod 16 retracts. Under the elastic squeezing force of the elastic telescopic rod 16, there is a certain damping feeling when rotating the threaded rod 5, which avoids random rotation and improves the stability of use.
