[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Reference Figure 1 , 2 As shown, a constant temperature milk heater includes a main unit 100, a heat-conducting cover 200, a connecting ring 300, and an expansion sleeve 400. A heating element 500 is arranged in the main unit 100; the heat-conducting cover 200 is arranged on the top of the main unit 100, and the heat-conducting cover 200 is used to contact and conduct heat with the heating element 500; the connecting ring 300 includes a first connecting portion 310 and a second connecting portion 320, the first connecting portion 310 is detachably connected to the heat-conducting cover 200, and the second connecting portion 320 is detachably connected to the milk bottle; the expansion sleeve 400 is detachably installed in the connecting ring 300, and the expansion sleeve 400 is connected to the first connecting portion The connecting portion 310 is pressed against the heat-conducting cover 200, and a heating space 401 is formed in the expansion sleeve 400, and the milk is heated in the heating space 401; an expansion space 201 is formed between the expansion sleeve 400 and the inner wall of the connecting ring 300, and the expansion sleeve 400 is made of elastic materials such as silicone or rubber. When the milk is heated, the expansion sleeve 400 will expand, and the expansion space 201 reserves space for the expansion of the expansion sleeve 400, and the expansion sleeve 400 includes an expansion portion 430, and when the heating element 500 is heating, the expansion portion 430 expands toward the expansion space 201.

[0026] First, before use, the expansion sleeve 400 is installed into the connecting ring 300, and then the first connecting part 310 of the connecting ring 300 is threadedly connected to the heat conductive cover 200, and then the bottle thread is installed into the second connecting part 320 of the connecting ring 300 to form a heating space 401 in the expansion sleeve 400. After starting the heating element 500, the milk is heated in the above-mentioned heating space 401. After the heating is completed, when cleaning, the connecting ring 300 and the expansion sleeve 400 are disassembled and soaked and rinsed, so that there is no dead corner for cleaning.

[0027] Secondly, since the heat-conducting cover 200 is arranged on the top of the host 100 and contacts the heating element 500, there is no connection gap between the heating element 500 and the heat-conducting cover 200. After the connecting ring 300 is removed, the cover surface of the heat-conducting cover 200 can be rinsed or scrubbed; and since the cover surface of the heat-conducting cover 200 is a plane, the heating area is increased, thereby improving the heating efficiency.

[0028] Reference Figure 1 , 3 As shown, a plurality of ventilation windows 330 are provided on the connecting ring 300, and the ventilation windows 330 are communicated with the expansion space 201, so that when the milk is heated, the air in the expansion space 201 can be squeezed out from the ventilation windows 330 into the external environment by the expansion portion 430 that expands due to the heat, thereby preventing the expansion of the expansion sleeve 400 from being restricted and causing damage to the expansion sleeve 400.

[0029] Reference Figure 3 , 4 As shown, the expansion sleeve 400 also includes a first sealing ring portion 410 and a second sealing ring portion 420. The first sealing ring portion 410 is pressed between the first connecting portion 310 and the heat conductive cover 200 to prevent milk from leaking from the gap between the heat conductive cover 200 and the connecting ring 300, thereby improving the sealing performance of the entire machine.

[0030] The second sealing ring portion 420 is installed at the second connecting portion 320, and the second sealing ring portion 420 is pressed tightly by the bottle mouth of the feeding bottle to prevent milk from leaking out of the gap between the connecting ring 300 and the bottle mouth of the feeding bottle when the feeding bottle is turned over, thereby improving the sealing performance of the whole machine.

[0031] In order to further improve the sealing performance, the cross-section of the second sealing ring portion 420 is U-shaped, and the second sealing ring portion 420 is pressed into the bottle mouth of the milk bottle to seep out, thereby improving the sealing performance of the whole machine.

[0032] The connecting ring 300 is a diameter-changing body, and forms a large-diameter first connecting portion 310 and a small-diameter second connecting portion 320 in the diameter change. The diameter of the second connecting portion 320 matches the diameter of the feeding bottle.

[0033] Reference Figure 3 , 4As shown, the heat conductive cover 200 is provided with a first thread 210 , and the inner side wall of the first connecting portion 310 is provided with a second thread 340 , and the first thread 210 is engaged with the second thread 340 .

[0034] A third thread 350 is provided on the inner side wall of the second connecting portion 320 , and the third thread 350 engages with the external thread of the bottle mouth of the feeding bottle.

[0035] Reference Figure 1 , 2 As shown, the host 100 includes an outer shell 110 and a mounting frame 120. The mounting frame 120 is arranged inside the outer shell 110. The heating element 500 is installed on the top of the mounting frame 120. The mounting frame 120 is connected to the heat-conducting cover 200. A rechargeable battery and a control panel are arranged inside the outer shell 110. The rechargeable battery is used for power supply. The control panel is controlled and linked to the heating element 500.

[0036] Reference Figure 5 As shown, in order to improve the stability of the thermal conductive cover 200 after installation, a bending portion 220 is bent at the cover opening of the thermal conductive cover 200, and a step portion 111 is provided at the top end port of the outer shell 110. The bending portion 220 is pressed against the step portion 111 by the first connecting portion 310, and a sealing ring 700 is clamped between the bending portion 220 and the step portion 111.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
