The stabilizing assembly includes a slide rod 6 , which is symmetrically fixedly connected to both sides of the bottom of the heating plate 503 . A spring 7 is sleeved on the outer side of the slide rod 6 , and a limit plate 8 is fixedly connected to the bottom of the slide rod 6 .
[0024] In the above technical solution, considering that there is a way to directly heat the water pipe, the repeated thermal expansion and contraction of the water pipe over a long period of time can easily cause damage to the water pipe, shorten its service life, and be unfavorable for long-term use. In order to solve this problem, the specific operations are as follows:
[0025] Reference Figure 1 - Figure 5In a preferred embodiment, water is injected into the inside of the meandering heating tube 506 through the water inlet pipe 504, and the heating plate 503 begins to conduct heat to the fixed rod 501. The heat of the fixed rod 501 is evenly transferred to the heat-conducting fins 502. When the water flows through the inside of the meandering heating tube 506, the heat-conducting fins 502 begin to heat the water, and the heated water is discharged through the water outlet pipe 505. At this time, the water flow will impact the heat-conducting fins 502 during the flow, causing the heat-conducting fins 502 to vibrate up and down. When the heat-conducting fins 502 vibrate, the heating plate 503 presses the spring 7 downward. Under the action of the expansion and contraction force of the spring 7, the vibration force of the heat-conducting fins 502 can be filtered and buffered, thereby avoiding long-term vibration and damage to the fins. By setting up the heat exchange mechanism 5, the water can be heated evenly and orderly, while also avoiding the situation where direct combustion heating of the pipeline causes pipeline damage and deformation, extending the service life, improving the heat exchange efficiency, and having a simple structure and strong practicality.
[0026] Reference Figure 1 - Figure 5 In a preferred embodiment, stabilizing plates 9 are symmetrically provided on both sides of the thermal fins 502, and stabilizing blocks 10 are fixedly connected at equal distances on the side of the stabilizing plate 9 close to the thermal fins 502. The height of the stabilizing block 10 is the same as the distance between two adjacent thermal fins 502. An air outlet pipe 11 is fixedly connected to the top of the box body 1, and an air suction head 12 is fixedly connected to the bottom of the air outlet pipe 11. Heat dissipation grooves 13 are equidistantly provided on both sides of the box body 1. A controller 14 is fixedly connected to the outside of the box body 1, and the nozzle 4 is electrically connected to the controller 14. The stabilizing plates 9 and stabilizing blocks 10 are provided to support the thermal fins 502 to avoid deformation. The controller 14 is provided to facilitate the staff to control the opening and closing of the nozzle 4, and the operation is simpler.
[0027] Working principle: When in use, the staff starts the nozzle 4 and starts to heat the heating plate 503. Water is injected into the inside of the circular heating tube 506 through the water inlet pipe 504. The heating plate 503 starts to conduct heat to the fixed rod 501. The heat of the fixed rod 501 is evenly transmitted to the thermal fins 502. When the water flows through the inside of the circular heating tube 506, the thermal fins 502 start to heat the water. The heated water is discharged through the water outlet pipe 505. At this time, the water flow will impact the thermal fins 502 during the flow, causing the thermal fins 502 to vibrate up and down. When the thermal fins 502 vibrate, the heating plate 503 presses the spring 7 downward. Under the action of the expansion and contraction force of the spring 7, the vibration force of the thermal fins 502 can be filtered and buffered to avoid long-term vibration and damage to the fins.
