[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Embodiment 1, by Figures 1-4 It is given that the utility model includes a cylinder 1, a water inlet pipe 2, a spring 3, a front end cover 4, a water outlet pipe 5, a rear end cover 6, a heating rod 7, a wire 8, a detection hole 9, a fixing plate 10 and a fixing hole 11. A water inlet pipe 2 is welded to the outer wall of the cylinder 1 near the edge. The water inlet pipe 2 is connected to the interior of the cylinder 1, and one end of the water inlet pipe 2 extends to the interior of the cylinder 1. A spring 3 is provided inside the cylinder 1, and one end of the spring 3 abuts against the extended section of the water inlet pipe 2. A front end cover 4 is welded to one end of the cylinder 1, and a water outlet pipe 5 is welded to one end of the front end cover 4. The water outlet pipe 5 is connected to the interior of the cylinder 1, and a rear end cover 6 is welded to the end of the cylinder 1 away from the front end cover 4, and a heating rod 7 is welded to one end of the rear end cover 6. The heating rod 7 is located inside the spring 3, and a heating wire is provided inside the heating rod 7. One end of the heating wire is connected to the wire 8, and the wire 8 extends to the outside of the rear end cover 6.

[0020] The water outlet pipe 5 is located at the eccentric end of the front end cover 4, and a detection hole 9 is formed at the outer end of the water outlet pipe 5 for installing a temperature sensor and a water flow sensor to detect the water temperature and whether there is water flow.

[0021] The fixed sheet 10 is welded on both sides of the lower end of the cylinder body 1, and a fixed hole 11 is formed at the upper end of the fixed sheet 10 to facilitate the installation and fixation of the device.

[0022] By Figure 5 Given, the device can replace the position of the water inlet pipe 2 with the wire 8 according to actual needs.

[0023] Working principle: water inlet and preliminary dispersion:

[0024] The water source enters the inside of the cylinder body 1 through the water inlet pipe 2, and under the action of the spring 3, the water flow is preliminarily dispersed;

[0025] Heating and spring 3 action:

[0026] The heating rod 7 is connected to the external power supply through the wire 8, and the heating wire generates heat inside the heating rod 7, which transmits heat to the water in the cylinder body 1;

[0027] The spring 3 is sleeved outside the heating rod 7, which not only increases the heating area and improves the heating efficiency, but also buffers the water pressure to a certain extent and improves the high-pressure resistance of the device. On the other hand, the spiral structure of the spring 3 enables the water flow to be more evenly distributed around the heating rod 7 during heating, further improving the heating effect;

[0028] Eccentric water outlet and dry burning prevention:

[0029] The water outlet pipe 5 is arranged at the eccentric end of the front end cover 4 and communicates with the inside of the cylinder body 1. This eccentric design ensures that the water outlet and the water inlet are not on the same horizontal line. When the water level in the cylinder body 1 drops, due to the design of the eccentric water outlet pipe 5, water is always retained at the bottom of the cylinder body 1. Even in the case of insufficient or interrupted water supply, dry burning phenomenon can be effectively prevented;

[0030] Intelligent monitoring and feedback:

[0031] The temperature sensor and the water flow sensor installed in the detection hole 9 can monitor the water temperature and the water flow state in real time;

[0032] When the water temperature exceeds the preset value, the temperature sensor will send a signal to turn off the power supply of the heating rod 7 through the control system to prevent safety accidents caused by high water temperature;

[0033] When the water flow sensor detects water flow interruption or abnormal water flow, it will also send a signal to take appropriate protective measures through the control system, such as turning off the power supply of the heating rod 7 or issuing an alarm prompt.

[0034] Stable structure and convenient installation:

[0035] The components such as the cylinder body 1, the front end cover 4 and the rear end cover 6 are connected together through welding process, which ensures the structural stability and sealing performance of the device;

[0036] The setting of the fixed sheet 10 and the fixed hole 11 makes the device easy to install and fix in various environments, improving the flexibility and convenience of use.

[0037] In summary, the high-pressure-resistant and dry-burning-resistant heating device realizes multiple functions such as efficient heating, dry-burning prevention, high-pressure resistance, etc. through the cooperation of the spring 3, the eccentric water outlet design and the intelligent monitoring system, and has wide application prospect and important social value.
