DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 6 As shown, the technical solution adopted by the utility model is as follows: a milk warmer that is easy to clean and has a heat preservation function, comprising a base 1, the bottom surface of the base 1 is fixedly connected with an anti-skid pad 9 to increase the friction of the base 1. The top surface of the base 1 is fixedly connected with a shell 2, the inner wall of the shell 2 is fixedly connected with an inner liner 7, the top surface of the shell 2 is placed with an upper cover 3, the bottom surface of the upper cover 3 is fixedly connected with a plug, and the outer circumferential surface of the plug matches the inner wall of the inner liner 7.

[0023] A rotating plate 11 is rotatably provided on the inner wall of the inner container 7, and a sealing ring is fixedly connected to the outer circumferential surface of the rotating plate 11. The rotating plate 11 divides the interior of the inner container 7 into a heating chamber and a cleaning chamber 17, and the heating chamber is located at the upper part of the cleaning chamber 17. A milk bottle body 18 is placed on the top surface of the rotating plate 11, and the milk bottle body 18 is located in the heating chamber.

[0024] Heating wires 8 are fixedly connected to the inner walls on both sides of the inner tank 7, and the outside of the heating wires 8 is wrapped with insulating materials. The two heating wires 8 are both located in the heating cavity.

[0025] Two NTC temperature sensors 6 are fixedly connected in the plug on the bottom of the upper cover 3. The detection ends of the two NTC temperature sensors 6 pass through the plug and extend into the heating chamber. A handle and a display panel 4 are fixedly connected to the top surface of the upper cover 3. The handle is convenient for taking the upper cover 3. The display panel 4 is electrically connected to the two NTC temperature sensors 6. The NTC temperature sensor 6 detects the temperature in the heating chamber, transmits the signal to the display panel 4, and displays it on the display panel 4.

[0026] A motor 10 is fixedly connected inside the base 1 . The output shaft of the motor 10 passes through the base 1 upward and extends into the cleaning chamber 17 . The output shaft of the motor 10 is fixedly connected to the bottom surface of the rotating plate 11 .

[0027] The outer circumferential surface of the upper end of the output shaft of the motor 10 is fixedly sleeved with a one-way bearing 13, which is located in the cleaning chamber 17, and the outer circumferential surface of the one-way bearing 13 is fixedly sleeved with a connecting piece 12. A drainage hole 16 connecting the heating chamber and the cleaning chamber 17 is opened on the rotating plate 11, and the connecting piece 12 rotates with the bottom surface of the rotating plate 11 to block the drainage hole 16. The interior of the connecting piece 12 is slidably connected to a limit pin 15, and the lower end of the limit pin 15 extends out of the connecting piece 12. The outer circumferential surface of the limit pin 15 is sleeved with a spring 14, which is located inside the connecting piece 12, and the upper end of the spring 14 is fixedly connected to the inner wall of the connecting piece 12, and the lower end is fixedly connected to the limit pin 15. The lower end of the limit pin 15 is arc-shaped, and the top surface of the base 1 is opened with a limit groove that matches the limit pin 15, and the inner wall of the limit groove is an arc surface.

[0028] A collecting groove is provided on the side of the base 1 , and the collecting groove is communicated with the cleaning chamber 17 . A collecting box 5 is slidably connected in the collecting groove, and a handle is fixedly connected to the outer side of the collecting box 5 .

[0029] Working principle: In summary, in the initial state, the connecting member 12 blocks the drainage hole 16.

[0030] When using the device, the personnel pulls the upper cover 3 upwards by the handle, and after removing the upper cover 3, the milk bottle body 18 is placed in the heating chamber so that the bottom surface of the milk bottle body 18 contacts the top surface of the rotating plate 11. Then the heating chamber is closed with the upper cover 3.

[0031] Then the personnel starts the heating wire 8 and the motor 10, and the heating wire 8 raises the temperature of the air in the heating chamber and continuously contacts the outer surface of the bottle body 18, thereby heating the inside of the bottle body 18. The output shaft of the motor 10 rotates, driving the rotating plate 11 to rotate, and the rotating plate 11 drives the bottle body 18 to rotate, so that the bottle body 18 is heated evenly.

[0032] At the same time, the output shaft of the motor 10 drives the one-way bearing 13 to rotate, the one-way bearing 13 drives the connecting piece 12 to rotate, and the connecting piece 12 drives the limiting nail 15 to rotate around the central axis of the output shaft of the motor 10. At this time, the connecting piece 12 and the rotating plate 11 are relatively stationary, and the connecting piece 12 blocks the drainage hole 16, preventing the hot air in the heating chamber from entering the cleaning chamber 17 from the drainage hole 16, thereby improving the heating efficiency.

[0033] When the limiting pin 15 moves out of the limiting groove, the limiting pin 15 slides toward the inside of the connecting member 12, the limiting pin 15 compresses the spring 14, and then the lower end of the limiting pin 15 continues to slide with the top surface of the base 1. When the limiting pin 15 moves into the limiting groove, the spring 8 pushes the limiting pin 15 to slide out of the inside of the connecting member 12, and the lower end of the limiting pin 15 matches the limiting groove.

[0034] Two NTC temperature sensors 6 detect the temperature in the heating chamber in real time and transmit the signal to the display panel 4, which displays the temperature in the heating chamber. The personnel can understand the temperature in the heating chamber through the display panel 4. When the temperature is heated to a suitable temperature, the upper cover 3 is removed by the handle, and then the milk bottle body 18 is taken out.

[0035] In the process of heating the bottle body 18, the hot air in the heating chamber contacts the cold bottle body 18, and the hot air is cooled to liquefy the water vapor in the air, forming water droplets on the outer surface of the bottle body 18 and flowing onto the rotating plate 11. If it is not cleaned for a long time, scale is easily generated.

[0036] After heating is completed, the personnel rotate the output shaft of the motor 10 in the opposite direction to drive the rotating plate 11 to rotate. When the rotating plate 11 rotates, the rotating plate 11 will rotate relative to the top surface of the connecting member 12. Since the limiting nail 15 is located in the limiting groove, the connecting member 12 will be prevented from rotating, and the outer ring of the one-way bearing 13 will not rotate at this time, so that the drainage hole 16 and the connecting member 12 end to cooperate, and the water in the heating chamber flows into the cleaning chamber 17 through the drainage hole 16, and then flows into the collection box 5. The heating wire 8 dries the water in the heating chamber.

[0037] After the cleaning is finished, the personnel turns off the motor 10 and the heating wire 8, and then closes the heating chamber with the upper cover 3. Then the collection box 5 is pulled out by the handle, and the water in the collection box 5 is poured out.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
