[0032] Figure 1 An explosion structure schematic diagram of the heating disc fixing structure of the milk warmer of an embodiment of the present disclosure is shown. Figure 2 A vertical section structure schematic diagram of the heating disc fixing structure of the milk warmer of an embodiment of the present disclosure is shown. Figure 3 A three-dimensional structure schematic diagram of the heating disc fixing structure of the milk warmer of an embodiment of the present disclosure after the shell is opened is shown. Please refer to Figure 1 , Figure 2 and Figure 3The milk warmer heating disc fixing structure comprises a kettle body 1, a base 4 and a heating disc 3. The kettle body 1 contains liquid. A connecting block 2 is arranged on the kettle body 1. The base 4 has a concave surface forming a containing cavity 43. The opening end of the containing cavity 43 is close to the kettle body 1. The base 4 is connected with the connecting block 2. The base 4 is connected with the kettle body 1 through the connecting block 2. When the kettle body 1 is made of glass or other materials that are difficult to connect, it is difficult to detachably connect the base 4 with the kettle body 1. At this time, the kettle body 1 is first fixedly connected with the connecting block 2, and then the base 4 is detachably connected with the connecting block 2, so that the heating disc 3 is convenient to disassemble, maintain and upgrade. The heating disc 3 is arranged in the containing cavity 43. The milk in the kettle body 1 is heated by the heating disc 3. The containing cavity 43 is provided with an elastic member 411 arranged between the heating disc 3 and the base 4. The elastic member 411 pushes the heating disc 3 to contact the kettle body 1, so as to realize the elastic connection between the heating disc 3 and the base 4. When the heating disc 3 heats the kettle body 1, the deformation amount of the heating disc 3 and the kettle body 1 is different due to the difference in material. At this time, the elastic deformation of the elastic member 411 compensates for the displacement difference between the kettle body 1 and the heating disc 3, the structure between the kettle body 1 and the heating disc 3 is stable, and the sealing failure and glass cracking caused by the difference in deformation amount between the kettle body 1 and the heating disc 3 are avoided.

[0033] In the embodiment, the fixing ring is a separate component. In other embodiments, the fixing ring can also be integrally formed with the kettle body 1. For example, when the kettle body 1 is made of a material that can be threadedly connected, the fixing ring is integrally arranged with the kettle body 1. At this time, the threaded fastener 6 passing through the support 41 is directly threadedly connected with the kettle body 1, further simplifying the milk warmer heating disc fixing structure. In some other embodiments, the fixing ring can also be integrally arranged with the support 41, that is, the support 41 is directly bonded with the kettle body 1 by glue.

[0034] Please refer to Figure 1 and Figure 2 The base 4 comprises an outer shell 42 and a support 41 arranged in the outer shell 42. The base is split into the support 41 and the outer shell 42. The outer shell 42 can be interference-fitted with the kettle body 1. The support 41 supports the heating disc 3, and the outer shell 42 wraps and protects the heating disc 3 and the support 41 and other structures. Compared with the integral base 4, the split arrangement of the support 41 and the outer shell 42 makes the structure of the components simpler and easier to process. When subsequent maintenance / upgrade is required, the support 41 or the outer shell 42 can be replaced separately, improving the convenience of product maintenance, iteration and expansion of the milk warmer heating disc fixing structure.

[0035] The bracket 41 is connected to the connecting block 2 on the kettle body 1. The elastic member 411 is arranged between the bracket 41 and the heating disc 3. The bracket 41 and the connecting block 2 can be connected by a threaded fastener 6 or a buckle fixing connection or other connection modes. When the bracket 41 is screwed to the connecting block 2 on the kettle body 1 by the threaded fastener 6. The connecting block 2 is provided with a threaded hole column 421. The bracket 41 is provided with a threaded hole corresponding to the threaded hole column 421. The threaded fastener 6 is connected to the threaded hole column 421 along the threaded hole. The threaded fastener 6 is connected between the bracket 41 and the connecting block 2 by thread engagement, has high connection strength, and can be repeatedly disassembled and connected, facilitating the maintenance of the heating disc fixing structure of the milk frother. The threaded fastener 6 can be a screw, a bolt, a stud, or the like. The threaded hole column 421 on the connecting block 2 ensures that there is a sufficient length of threaded connection section between the connecting block 2 and the threaded fastener 6, and at the same time, the threaded hole column 421 on the connecting block 2 can abut against the bracket 41, limiting the distance between the bracket 41 and the connecting block 2, and improving the stability of the connection between the bracket 41 and the connecting block 2. The threaded fastener 6 between the connecting block 2 and the bracket 41 can be provided in multiple numbers, and the multiple threaded fasteners 6 jointly threadedly connect the base 4 and the connecting block 2.

[0036] In some embodiments, the bracket 41 also extends a threaded hole column 421 on the side close to the shell 42, and the shell 42 is provided with a threaded hole corresponding to the threaded hole column 421 on the bracket 41. The threaded fastener 6 connects the threaded hole column 421 on the bracket 41 to the threaded hole on the shell 42, and the threaded fastener 6 threadedly connects the bracket 41 and the shell 42. The threaded hole column 421 on the bracket 41 ensures that there is a sufficient length of threaded connection section between the bracket 41 and the threaded fastener 6, and guarantees the connection strength between the threaded fastener 6 and the bracket 41. At the same time, the threaded hole column 421 can abut against the shell 42, determine the gap width between the bracket 41 and the shell 42, and guarantee the stability of the connection between the bracket 41 and the shell 42.

[0037] In the above embodiments, the bracket 41 and the connecting block 2 are separate components, and in other embodiments, the bracket 41 and the connecting block 2 can also be integrated components. That is, the integrated component includes the bracket 41 part and the connecting block 2 part, the connecting block 2 part directly connects the kettle body 1, and the bracket 41 part supports the elastic member 411.

[0038] In some embodiments, the elastic member 411 can also be a large elastic member 411. A large elastic member 411 is arranged between the heating disc 3 and the bracket 41, that is, the elastic connection between the heating disc 3 and the bracket 41 is realized. For example, the elastic member 411 can be an integrated elastic ring. The heating disc 3 and the bracket 41 are respectively provided with a limiting groove 412, and the position of the annular elastic member 411 is fixed by the upper and lower limiting grooves 412.

[0039] Preferably, the connecting block 2 is recessed near the surface of the kettle body 1 to form a connecting groove 21. The connecting groove 21 is filled with glue. Filling the glue in the connecting groove 21 reduces the risk of glue overflow when the connecting block 2 is bonded with the kettle body 1. At the same time, the connecting groove 21 can quickly locate the glue application position and the amount of glue applied, which is convenient for the operator to apply glue. At the same time, the connecting groove 21 flows out of the gap between the connecting block 2 and the kettle body 1. When the threaded fastener 6 connects the bracket 41 with the connecting block 2, the threaded fastener 6 can extend into the connecting groove 21 after passing through the connecting block 2, avoiding damage to the kettle body 1.

[0040] More preferably, the connecting block 2 is circular in shape. The base 4 connects the annular side of the connecting block 2. Specifically, the structure of the milk frother is mostly cylindrical, and correspondingly, the outer shape of the heating disc 3 is also set to be disc-shaped, so as to expand the contact area between the heating disc 3 and the kettle body 1, and then quickly heat the milk liquid in the kettle body 1. At this time, the connecting block 2 is set to be circular, which does not interfere with the connection of the coupler 5 with the kettle body 1, and can increase the connection area between the connecting block 2 and the bracket 41, thereby enhancing the strength and stability of the bracket 41 fixation.

[0041] Please refer to Figure 1 and Figure 2 A through hole 422 is formed on the base 4, and the cable connected with the heating disc 3 passes through the base 4 along the through hole 422. The coupler 5 is also arranged in the cavity 43. The input end of the coupler 5 extends out of the through hole 422 and is connected with the driving shaft. The output end of the coupler 5 extends into the kettle body 1 beyond the heating disc 3. The output end of the coupler 5 extending into the kettle body 1 can be connected with a baby bottle in the kettle body 1, so as to realize the rotation of the baby bottle. While the heating disc 3 heats the baby bottle in the kettle body 1, the baby bottle is driven to rotate by the coupler 5, so as to shake the milk liquid in the baby bottle evenly. The milk shaking function is realized.

[0042] Preferably, a sealing ring 51 is sleeved on the output end of the coupler 5. The outer diameter of the output end of the coupler 5 is contracted to form a shoulder 52. The sealing ring 51 is arranged between the shoulder 52 and the outer surface of the kettle body 1. The sealing performance between the coupler 5 and the kettle body 1 is guaranteed by the sealing ring 51. The shoulder 52 cooperates with the kettle body 1 to clamp the sealing ring 51.

[0043] More preferably, the heating disc 3 is annular. The annular heating disc 3 can be arranged around the coupler 5 to avoid interference between the heating disc 3 and the coupler 5, while maximizing the contact area with the kettle body 1. Increasing the contact area between the heating disc 3 and the kettle body 1 allows the heat of the heating disc 3 to be more evenly transmitted to the entire bottom of the container, avoiding local overheating or uneven temperature of the kettle body 1. At this time, the hole wall of the annular heating disc 3 contacts the sealing ring 51. Further limit the position of the sealing ring 51 to avoid the position offset of the sealing ring 51 affecting the sealing effect between the kettle body 1 and the coupler 5.

[0044] Please refer to Figure 1 andFigure 2 A limiting post 31 is arranged on the heating disc 3 or the base 4. Correspondingly, a limiting slot 412 is arranged on the base 4 or the heating disc 3 in alignment with the limiting post 31. An elastic member 411 is sleeved on the limiting post 31 and extends into the limiting slot 412. The position of the elastic member 411 is limited by the limiting post 31 and the limiting slot 412, so that the elastic contact is ensured and the heating disc 3 is pushed to the kettle body 1. In the embodiment, the elastic member 411 is a spring.

[0045] Preferably, at least three elastic members 411 are arranged around the center of the heating disc 3. The three or more elastic members 411 are arranged evenly in the circumferential direction around the center of the heating disc 3 to stably support the heating disc 3.

[0046] The specific working process of the utility model is as follows:

[0047] When assembling the heating disc 3, first fill the glue in the connecting groove 21, and bond the connecting block 2 and the kettle body 1 through the glue. Then put the elastic member 411 into the limiting slot 412 of the bracket 41. Then move the heating disc 3, align the position of the limiting post 31 on the heating disc 3 and the elastic member 411 on the bracket 41, and place the heating disc 3 on the bracket 41. Then align the screw hole column 421 on the connecting block 2 and the screw hole on the bracket 41, and connect the screw hole column 421 on the connecting block 2 along the screw hole on the bracket 41 by the threaded fastener 6, so as to screw connect the bracket 41 and the connecting block 2. Then move the coupling 5, and extend the output end of the coupling 5 into the kettle body 1. Move the shell 42, align the screw hole column 421 on the bracket 41 and the screw hole on the shell 42, connect the screw hole column 421 on the bracket 41 along the screw hole on the shell 42 by the threaded fastener 6, screw connect the shell 42 and the bracket 41, and complete the assembly of the heating disc 3.

[0048] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0049] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
