[0022] Please refer to Figures 1-5 As shown in the drawings, the infusion heating insulation hose provided by the present application comprises a lower tube 11 formed by molding, an upper tube 12 formed by liquid injection, a heating wire 2 and a temperature sensor 3. The lower tube 11 is provided with a heating wire groove 112 penetrating through front and back and a temperature sensor groove 111 not penetrating through. The heating wire 2 and the temperature sensor 3 are respectively installed in the heating wire groove 112 and the temperature sensor groove 111 and are sealed by the upper tube 12 formed by liquid injection, so as to effectively fill and wrap the heating wire 2 and the temperature sensor 3. The upper tube 12 and the lower tube 11 are fused and connected to form an integrated heating tube 1. The heating tube 1 is provided with a clamping groove 121 in the center for wrapping an infusion tube. The technical solution is designed in a split type. The heating wire 2 and the temperature sensor 3 are first installed on the formed lower tube 11, then the melted soft glue is poured into a mold and the heating wire 2 and the temperature sensor 3 are wrapped, and after cooling, the integrated heating tube 1 is formed. In this solution, the heating wire 2 is no longer subjected to traction force and extrusion force, and will not be broken. The melted glue effectively wraps the temperature sensor 3, and there is no air around the temperature sensor 3, so the measurement accuracy is higher.

[0023] As Figure 1 shown, the two ends of the formed heating tube 1 are placed in the mold, liquid injection molding is performed, a sheath 4 is formed to protect the internal circuit from the external environment. The sheath 4 at one end of the heating tube 1 is integrally connected with a connector 6, and the connector 6 is electrically connected with the heating wire 2 and the temperature sensor 3, so as to facilitate the user to connect with a control device through the connector 6.

[0024] As Figure 3As shown, the heating wire 2 inside the heating tube 1 is configured in two or more sections, each with a different heating power. The heating intensity can be adjusted according to the needs of different parts, improving heating efficiency and safety. There are two or more heating wires 2, evenly distributed around the clamping groove 121. The connection points between the heating wires 2 are wrapped with insulating sleeves 5 to ensure electrical safety and prevent short circuits.

[0025] To gain a more thorough and comprehensive understanding of the disclosure of this utility model, its principles will be further explained below in conjunction with its usage.

[0026] During production, the lower tube 11 is first molded, such as... Figure 2 As shown, the lower tube 11 has a through-hole heating wire groove 112 and a non-through-hole temperature sensor groove 111 on its surface. Next, the heating wire 2 and the temperature sensor 3 are respectively installed in the heating wire groove 112 and the temperature sensor groove 111, as shown. Figure 3 As shown.

[0027] The lower tube 11, with the heating wire 2 and temperature sensor 3 installed, is placed in a liquid molding mold and liquid injection molded, so that the liquid tube wraps around the heating wire 2 and the sensor. After cooling and solidification, it is as follows: Figure 4 .

[0028] like Figure 5 As shown, the exposed heating wire 2 and temperature sensor 3 wires at both ends are twisted together and soldered; the solder joint is then covered with heat shrink tubing or insulating sleeve 5. This part forms an electrical circuit and a temperature sensing feedback circuit.

[0029] Finally, the two ends of the heating element 1 are placed in the mold and liquid injection molded to form a sheath 4 to protect the internal circuit from the influence of the external environment. The sheath 4 at one end of the heating element 1 is integrally connected to the connector 6. The connector 6 is electrically connected to the heating wire 2 and the temperature sensor 3, making it convenient for the user to connect to the control device through the connector 6.

[0030] In this embodiment, as Figure 3 As shown, the heating wire 2 is divided into two sections. The front section heating wire 21 has a higher power to quickly heat up the liquid in the infusion tube, while the rear section heating wire 22 has a lower power to keep the infusion tube warm after heating, ensuring that the liquid in the infusion tube remains stable at the preset temperature and reducing fluctuations.
