[0024] When in use, the heating tank body 11 is a heating tank commonly used in the prior art, and is provided with an electric heating tube, a thermostat and a temperature sensor therein to meet the requirements of the prior art for heating and sterilizing milk. When in use, the submersible pump 14 draws water from the heating tank body 11, and then injects the hot water into the heat conducting tube 18 through the connecting tube 16 and the tube seat 17. The partition 19 in the heat conducting tube 18 divides it into a U-shaped pipe so that hot water can flow inside it. By setting up a plurality of heat conducting tubes 18 and inserting them into the interior of the milk in the inner tank 12, the milk in the center can be heated to improve the uniformity of heating. Compared with the stirring method, it can reduce the separation of milk fat due to stirring.

[0026] Further, such as Figure 2-4 As shown, the middle part of the push plate 22 is rotatably connected with a screw rod 31; the top end of the screw rod 31 is fixedly connected with a stirring blade 32; the bottom of the heating tank body 11 is fixedly connected with a nut 33; the screw rod 31 passes through the nut 33 and is threadedly connected thereto; the bottom of the heating tank body 11 is fixedly connected with a closed tube 34; the screw 31 is located in the middle part of the closed tube 34; when in use, the movement of the push plate 22 will drive the screw rod 31 to move upward, and since the nut 33 is fixed, the upward movement of the screw rod 31 will cause it to rotate, thereby driving the stirring blade 32 to rotate, and the rotation of the stirring blade 32 can stir the water in the inner tank 12, thereby improving the cleaning effect of the inner tank 12.
[0027] Further, such as Figure 2-4As shown, a water injection hole is opened in the middle of the screw 31; a nozzle 41 is fixedly connected to the top of the water injection hole; a spherical mesh cover 42 is fixedly connected to the top of the screw 31; the nozzle 41 is located inside the spherical mesh cover 42; the bottom end of the screw 31 is connected to a flexible tube 43 through a rotating pipe joint; the flexible tube 43 passes through the bottom of the closed tube 34 and is fixedly connected thereto; when in use, the flexible tube 43 is connected to an external water pump, the water pump fills water, and then water is injected into the water injection hole through the flexible tube 43 and the rotating pipe joint, and then the water is ejected outward from the nozzle 41, and the ejected water is ejected from the holes on the spherical mesh cover 42, so as to disperse it into multiple small water flows to rinse the inside of the inner tank 12, thereby further improving the cleaning effect and reducing milk residue.
[0028] Further, such as Figure 4 As shown, an annular mesh cover 61 is fixedly connected to the inner wall of the bottom of the heating tank body 11; a top cover 62 is fixedly connected to the top of the annular mesh cover 61; the side end of the pipe seat 17 passes through the annular mesh cover 61 and is fixedly connected to it; when in use, the hot water flowing out of the heat pipe 18 will be injected into the annular mesh cover 61 through the pipe seat 17, and the hot water flowing out from the holes of the annular mesh cover 61 will be mixed with other hot water, thereby disrupting the water flow in the heating tank body 11 and mixing it, thereby facilitating improving the uniformity of the water temperature of the heating tank body 11.
[0029] Further, such as Figure 2 As shown, a drainage cover 7 is fixedly connected to the top of the inner tank 12. When in use, a small amount of solid precipitation will be generated when the milk is heated. When the push plate 22 moves to the top of the inner tank 12, the remaining water and some solid precipitation on the push plate 22 will fall into the drainage covers 7 on both sides, thereby reducing the situation where water is pumped out through the silicone tube 15 and residual water in the push plate 22.
[0030] Working principle: when in use, the heating tank body 11 is a commonly used heating tank in the prior art, and has an electric heating tube, a thermostat and a temperature sensor inside, so as to meet the requirements of the prior art for heating and sterilizing milk. When this embodiment is in use, the submersible pump 14 will extract water from the heating tank body 11, and then inject the hot water into the heat pipe 18 through the connecting pipe 16 and the pipe seat 17. The partition 19 in the heat pipe 18 separates it into a U-shaped pipe, so that hot water can flow inside it. By setting a plurality of heat pipes 18 to be inserted into the milk in the inner tank 12, the heat pipe 18 can be heated and sterilized. This can heat the milk at the center to improve the uniformity of heating, and compared with the stirring method, it can reduce the separation of milk fat caused by stirring. Multiple silicone tubes 15 are used to inject milk, inject water and flush the inner tank 12, and pump water. When the milk is injected into the inner tank 12, the milk is located on the top of the push plate 22. After the milk is pumped out, the silicone tube 15 is injected and flushed, and the hydraulic cylinder 21 pushes the push plate 22 upward, so that the milk on the inner wall of the inner tank 12 and the heat conducting tube 18 can be scraped off, thereby reducing milk residue and facilitating entry. The first seal 51 is used to seal between the push plate 22 and the inner wall of the inner tank 12, and the second seal 52 is used to seal the connection between the heat conducting pipe 18 and the through hole. The movement of the push plate 22 will drive the screw 31 to move upward. Since the nut 33 is fixed, the upward movement of the screw 31 will cause it to rotate, thereby driving the stirring blade 32 to rotate. The water in the inner tank 12 can be stirred by the rotation of the stirring blade 32, so as to improve the cleaning effect of the inner tank 12. The flexible tube 43 is connected to the external water pump, the water pump is filled with water, and then the water is pumped through the flexible tube 43 and the rotating tube The joint injects water into the water injection hole, and then the water is ejected outward from the nozzle 41, and the ejected water is ejected from the holes on the spherical mesh cover 42, so as to disperse it into multiple small water flows to rinse the inside of the inner tank 12, so as to further improve the cleaning effect and reduce milk residue. When in use, the hot water flowing out of the heat pipe 18 will be injected into the annular mesh cover 61 through the pipe seat 17, and the hot water flowing out from the holes of the annular mesh cover 61 will be mixed with other hot water, so as to disrupt the water flow in the heating tank body 11 and mix it, thereby facilitating the improvement of the water temperature uniformity of the heating tank body 11.
