The three-way hole 7 is connected to the left side of the buffer chamber 8, and its upper opening is connected to the lower side of the heating chamber 15. Several guide plates 11 are arranged vertically and fixedly connected to the inside of the heating chamber 15 in an alternating manner. The heating tube 12 is fixedly connected to the inside of the heating chamber 15. The lower opening of the return chamber 6 is connected to the lower opening of the heat exchange tube 4. The piston 9 is movably connected to the inside of the buffer chamber 8, and a spring 10 is provided between the right side of the piston 9 and the right side of the inside of the buffer chamber 8. The delivery pump 13 is fixedly connected to the inside of the upper left side of the housing 5, and its lower inlet is connected to the upper side of the heating chamber 15. The adjusting device 14 is fixedly connected to the outside of the upper right side of the housing 5, and its left inlet is connected to the right outlet of the delivery pump 13, and its right outlet is connected to the upper opening of the heat exchange tube 4.

[0017] like Figure 2 and Figure 3 As shown, the specific structure of the regulating device 14 includes a valve body 141, a motor 142, a valve core 143, a valve hole 144, a first arc groove 145, an output hole 146, a conveying groove 147, an input hole 148, and a second arc groove 149; the motor 142 is fixedly connected to the upper interior of the valve body 141; the valve core 143 is externally and movably connected to the lower interior of the valve body 141, and the upper center of the valve core 143 is fixedly connected to the lower output shaft of the motor 142; there are several valve holes 144, and the several valve holes 144 are arranged vertically. Arranged and disposed inside the valve core 143, several valve holes 144 are respectively provided with arc grooves 145 of different arc lengths on the right side, and several valve holes 144 are respectively provided with arc grooves 149 of different arc lengths on the left side; there are several output holes 146, which are respectively located on the right side of the corresponding valve holes 144, and all of the output holes 146 are opened inside the right side of the valve body 141; the conveying groove 147 is opened inside the left side of the valve body 141, and the center of the left side of the conveying groove 147 is provided with an input hole 148.

[0018] The motor 142 is a servo motor or a stepper motor; the heat exchange tube 4 is a Teflon tube; and the end of the guide plate 11 is arc-shaped.

[0019] The utility model is used as follows: It features a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, the heating tube 12 is first energized and heats the liquid in the heating chamber 15. The heated liquid, under the action of the delivery pump 13, enters through the lower inlet of the pump 13, flows out from its right outlet, and enters the input hole 148 of the regulating device 14. Subsequently, it flows into the delivery trough 147. At this time, the motor 142 drives the valve core 143 to rotate according to the set program, thereby changing the valve hole 144 and... The relative position of the output holes 146 controls the liquid flow rate. Since the right side of the valve hole 144 has arc grooves 145 of different arc lengths, and the left side has arc grooves 149 of different arc lengths, when the valve core 143 rotates, the flow rate of liquid from the valve hole 144 to the output hole 146 and the opening / closing of the valve hole 144 at different positions can be adjusted. This, in turn, regulates the liquid flow rate into the heat exchange tube 4 and the number of working heat exchange tubes 4. The liquid flowing out from the right outlet of the regulating device 14 enters the upper opening of the heat exchange tube 4 for heat exchange. The liquid flows through tube 4 (Teflon tube), transferring heat to the filling layer 3 and the pad 1, thus achieving the heating and insulation function of the heating pad. After heat exchange, the liquid flows into the return chamber 6 through the lower opening of the heat exchange tube 4, and then enters the buffer chamber 8 through the three-way hole 7. In the buffer chamber 8, the liquid pushes the piston 9 to the right, compressing the spring 10. When the elastic force of the spring 10 is balanced with the liquid pressure, the piston 9 stops moving, allowing the liquid to briefly stay and buffer in the buffer chamber 8. Afterward, it re-enters the heating chamber 15 through the upper opening of the three-way hole 7, and so on, ensuring the heating pad's heating function. The heating pad works continuously and stably. Inside the heating chamber 15, the liquid is guided by the vertically arranged and staggered flow guide plates 11 (with rounded ends), making the liquid flow more uniform and stable, further improving heating efficiency and temperature uniformity. Throughout the process, the Teflon layer 2 on the outer surface of the pad 1 provides waterproof, anti-fouling, and corrosion-resistant protection, improving the safety and durability of the heating pad. In addition, the heat exchange tube 4 is used for heat transfer, thus ensuring safety during long-term use.
