Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a liquid heating container. Background Technology

[0002] Electric kettles, as convenient and reliable water heating containers, have become indispensable household items. Electric kettles rely on a heating element assembly for heating, and the positioning structure of this assembly directly affects the kettle's heating efficiency.

[0003] In related technologies, a heating plate bracket is typically installed below the heating plate for support, while the upper part is supported by ribs on the inner wall of the kettle. This bracket and ribs restrict the heating plate's vertical movement. However, this installation method suffers from poor reliability, leading to a risk of displacement of the heating plate during operation and affecting heating efficiency. Utility Model Content

[0004] This application provides a liquid heating container that can improve the stability and reliability of heating plate installation.

[0005] This application provides a liquid heating container, the liquid heating container comprising:

[0006] container body;

[0007] A heating assembly, comprising a heating plate, a mounting portion, and a bracket;

[0008] The heating plate is welded to the mounting part, and the bracket is detachably connected to the mounting part;

[0009] The heating component is mounted on the container body via the bracket.

[0010] In this design, the heating plate is welded to the mounting part, and the bracket is detachably connected to the mounting part, thus integrating the heating plate, mounting part, and bracket into a single unit (i.e., heating assembly). The heating assembly is then mounted onto the container body via the bracket. Because the connection between the heating plate and the mounting part is highly reliable after welding and is not easily separated, and because the heating assembly is mounted onto the container body via the bracket, the installation reliability of the heating plate is high, preventing shaking during use of the liquid heating container. This improves the installation reliability of the heating plate and heating assembly, thereby increasing heating efficiency. Furthermore, in this embodiment, the heating plate does not require internal ribs on the inner wall of the container to restrict upward displacement, reducing the manufacturing difficulty of the container body.

[0011] In one possible design, the outer periphery of the heating plate has a first extension, and the mounting portion is welded to the first extension.

[0012] In this design, the mounting part is welded to the first extension part, instead of being welded to the main body of the heating plate used for heating, thereby avoiding damage to the main body of the heating plate during the welding process and reducing heating efficiency.

[0013] In one possible design, the first extension has a receiving cavity, and the mounting portion is an annular structure located within the receiving cavity.

[0014] In this design, when the mounting part is housed within the receiving cavity of the first extension, the mounting part does not occupy the external space of the heating plate, thus improving the structural compactness of the liquid heating container. Simultaneously, when the mounting part is located within the receiving cavity, the sidewalls of the receiving cavity provide constraint on the mounting part, further enhancing the connection reliability between the mounting part and the first extension.

[0015] In one possible design, the bracket and the mounting part are connected by fasteners. This connection method ensures high reliability between the mounting part and the bracket, and facilitates disassembly and replacement.

[0016] In one possible design, the mounting portion has a second extension extending along the height direction of the liquid heating container, the second extension having a first mounting hole for engaging with a fastener, and the bracket having a second mounting hole for engaging with a fastener.

[0017] In this design, the second extension can increase the connection area between the fastener and the mounting part, thereby improving the connection reliability between the mounting part and the bracket.

[0018] In one possible design, a plurality of second extensions are spaced apart circumferentially along the mounting portion, and a plurality of second mounting holes are spaced apart circumferentially along the bracket. The plurality of circumferentially distributed second extensions and mounting holes ensure that the mounting portion and the bracket are connected at various circumferential positions, thereby further improving the stability of the mounting of the mounting portion and the bracket.

[0019] In one possible design, the bracket has a buckle extending outward in the circumferential direction, and the container body has a first slot. The bracket and the container body are engaged via the buckle and the first slot. This engagement of the bracket and the container body facilitates installation, provides a stable installation structure, and simplifies the structure of both the container body and the bracket.

[0020] In one possible design, the support includes an annular body and a third extension located on the outer periphery of the body, with a plurality of latches spaced apart on the outer peripheral wall of the third extension. The outwardly extending third extension and the latches on the outer periphery of the third extension facilitate connection of the support to the container body.

[0021] In one possible design, the liquid heating container further includes a sealing ring fitted around the outside of the heating assembly, with an interference fit between the sealing ring and the inner wall of the container body. This sealing ring seals the gap between the heating assembly and the container body, preventing liquid from the inner cavity of the container from entering the heating assembly and damaging the heating element.

[0022] In one possible design, the sealing ring includes a fourth extension extending radially inward along the height direction of the liquid heating container, the fourth extension being located between the first extension of the heating plate and the support. The fourth extension prevents liquid from entering the receiving cavity of the first extension, thereby preventing liquid from entering the cavity formed by the bottom cover and the heating assembly, which could cause damage to the circuitry or components.

[0023] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0062] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0063] This application provides a liquid heating container, such as... Figure 1 and Figure 2 As shown, the liquid heating container includes a lid assembly 1, a body assembly 2, a heating assembly 4, and a base 5. The body assembly 2 includes a container body 21, a bottom cover 22, and a handle 23. The bottom cover 22 is connected to the bottom of the container body 21, and the handle 23 is connected to the container body 21. The heating assembly 4 includes a heating plate 41, which is mounted on the body assembly 2, and the heating plate 41 and the container body 21 form a first cavity for containing liquid. The heating plate 41, the bottom cover 22, and the container body 21 form a second cavity for accommodating a first connector of the body assembly 2. The base 5 has a second connector; when the body assembly 2 is placed on the base, the first connector of the body assembly 2 couples with the second connector of the base.

[0064] When the liquid heating container is in operation, liquid is added into the container body 21. After being powered on, electricity is supplied to the heating plate 41 through the first and second connectors that are coupled to each other. After being powered on, the heating plate 41 generates heat and heats the liquid in the container body 21 through heat conduction, thereby realizing the function of liquid heating.

[0065] Specifically, the heating assembly 4 in this embodiment further includes a mounting part 42 and a bracket 43. The heating plate 41 is welded to the mounting part 42, and the bracket 43 is detachably connected to the mounting part 42, so that the heating plate 41, the mounting part 42 and the bracket 43 are connected as a whole (i.e., the heating assembly 4). When the bracket 43 of the heating assembly 4 is installed on the container body 21, the heating plate 41 is installed on the container body 21.

[0066] In this embodiment, when the heating component 4 is installed as a whole onto the container body 21 via the bracket 43, the connection between the heating plate 41 and the mounting part 42 after welding is highly reliable and not easily separated. Furthermore, the installation reliability of the heating plate 41 via the bracket 43 onto the container body 21 is high, preventing shaking during use of the liquid heating container. This improves the installation reliability of the heating plate 41 and the heating component 4, thereby increasing heating efficiency. Simultaneously, in this embodiment, the heating plate 41 does not require internal ribs on the inner wall of the container body 21 to restrict its upward displacement, reducing the processing difficulty of the container body 21.

[0067] In one specific embodiment, such as Figure 3 and Figure 4 As shown, the heating plate 41 includes a main body 412 and a first extension 411. The main body 412 is the key heating component, which is used to heat the liquid in the liquid heating container after being powered on. The first extension 411 is connected to the outer peripheral wall of the main body 412, that is, the first extension 411 is located on the outer periphery of the heating plate 41.

[0068] For details, see Figure 3 and Figure 4 The mounting part 42 is welded to the first extension part 411, instead of being welded to the main body 412 of the heating plate 41 used for heating, thereby avoiding damage to the main body 412 of the heating plate 41 during the welding process and reducing the heating efficiency.

[0069] In one specific embodiment, such as Figure 3 As shown, the first extension 411 on the outer periphery of the heating plate 41 has a receiving cavity 4111. The mounting part 42 has an annular structure and is placed inside the receiving cavity 4111. The mounting part 42 is welded to the first extension 411 within the receiving cavity 4111. In this embodiment, when the mounting part 42 is housed within the receiving cavity 4111 of the first extension 411, the mounting part 42 does not occupy the external space of the heating plate 41, improving the structural compactness of the liquid heating container. Simultaneously, when the mounting part 42 is located within the receiving cavity 4111, the sidewall of the receiving cavity 4111 can provide constraint on the mounting part 42, further improving the connection reliability between the mounting part 42 and the first extension 411. Furthermore, the annular structure of the mounting part and the first extension has a larger connection area, resulting in higher connection reliability.

[0070] In one specific embodiment, see Figure 2 , Figure 3 The mounting part 42 and the bracket 43 are detachably connected by fasteners 6, which makes the connection between the mounting part 42 and the bracket 43 highly reliable and allows the mounting part 42 and the bracket 43 to be disassembled so that when the welding structure between the heating plate 41 and the mounting part 42 or the bracket 43 is damaged, it can be replaced.

[0071] Specifically, the fastener 6 can be a component such as a screw.

[0072] In one specific embodiment, such as Figure 5 As shown, the lower surface of the mounting portion 42 is provided with a plurality of second extension portions 422 extending downward along the height direction, and the interior of each second extension portion 422 has a first mounting hole 421. See also Figure 6 The body 431 of the bracket 43 has a second mounting hole 4311. When the mounting part 42 is connected to the bracket 43, the second extension 422 of the mounting part 42 abuts against the body 431 of the bracket 43, and the first mounting hole 421 communicates with the second mounting hole 4311, so that the bracket 43 and the mounting part 42 are connected by the fastener 6.

[0073] When the fastener 6 is a screw, the screw passes through the second mounting hole 4311 and the first mounting hole 421 from below the body 431 of the bracket 43, tightening the bracket 43 and the mounting part 42 together. The second extension 422 provides adjustment space for the screw insertion depth, facilitating adjustment of the tightness of the connection between the bracket 43 and the mounting part 42. The screw connection is simple to install, facilitating the disassembly and installation of the mounting part 42 and the bracket 43.

[0074] In other specific embodiments, the mounting part 42 and the bracket 43 can also be connected by other detachable connection methods, such as rivet connection, snap-fit ​​connection, etc. This application does not limit the detachable connection method between the mounting part 42 and the bracket 43.

[0075] Specifically, at least two second extensions 422 are distributed circumferentially along the mounting portion 42, and correspondingly, at least two second mounting holes 4311 are distributed circumferentially along the bracket 43, and the number of second mounting holes 4311 corresponds one-to-one with the number of second extensions, thereby further improving the stability of the mounting portion 42 and the bracket 43.

[0076] The multiple second extensions 422 can be evenly distributed circumferentially, and the second mounting holes 4311 can be evenly distributed circumferentially, thereby improving the installation reliability of the mounting part 42 and the bracket 43 at each position.

[0077] In the above embodiments, after the structure of the bracket 43 welded to the mounting part 42 and the heating plate 41 is detachably connected to form the heating component 4, the heating component 4 is fixed inside the container body 21 by the connection between the bracket 43 and the container body 21.

[0078] For details, see Figure 3 , Figure 7 The container body 21 has a first slot 211 distributed circumferentially at its lower part, and the bracket 43 has a buckle 4321 extending outward circumferentially. The number of buckles 4321 and the first slot 211 of the container body 21 are equal and their positions correspond. When the heating component 4 is installed on the container body 21, the buckle 4321 of the heating component 4 engages with the first slot 211, realizing the engagement between the heating component 4 and the container body 21. After engagement, the heating component 4 is not easily detached from the container body 21, thereby reducing the risk of displacement of the heating plate 41 during the use of the liquid heating container.

[0079] More specifically, such as Figure 6 As shown, the bracket 43 includes an annular body 431 and a third extension 432 located on the outer periphery of the body 431. The buckle 4321 is located on the outside of the third extension 432 and is evenly spaced along the circumference. The buckle is used to engage with the first slot of the container body.

[0080] When installing the heating component into the container body, such as Figure 3 As shown, the heating component 4 enters from the lower opening of the container body 21 and extends upward until the buckle 4321 engages with the first slot 211. The installation process is simple and convenient, and it is easy to disassemble.

[0081] See details Figure 7 The container body 21 has a second slot 212 distributed circumferentially below it, which is located below the first slot 211 along the height direction of the container body 21; the bottom cover 22 is engaged with the container body 21 through the second slot 212. The structure has sufficient strength and is easy to replace and repair in case of damage.

[0082] In the above embodiments, such as Figure 2 As shown, the liquid heating container may also include a sealing ring 3, which is used to seal the gap between the heating component 4 and the container body 21 to prevent liquid in the inner cavity of the container body 21 from entering the heating component 4.

[0083] Specifically, such as Figure 3 As shown, the sealing ring 3 is sleeved on the outside of the heating component 4, and the sealing ring 3 is interference-fitted with the inner wall of the container body 21, thereby improving the sealing reliability.

[0084] More specifically, such as Figure 3 As shown, a waterproof rib 31 is provided on the side of the sealing ring 3 that contacts the container body 21, and the waterproof rib 31 is interference-fitted with the container body 21.

[0085] Specifically, two waterproof ribs 31 are spaced apart along the height of the sealing ring 3 on the side facing the container body 21. The waterproof ribs 31 encircle the outer surface of the sealing ring 3, and the outermost waterproof rib 31 has a triangular cross-section. The two circumferential waterproof ribs 31 provide a double-layer seal; even if the upper waterproof rib 31 fails, the lower waterproof rib 31 can still provide a seal, preventing water from flowing into the base assembly 5. Simultaneously, the interference fit between the sealing ring 3 and the container body 21 further secures the heating plate 41, preventing displacement.

[0086] Specifically, the sealing ring 3 is disposed on the outer surface of the first extension 411 of the heating plate 41 and abuts against the outer surface of the first extension 411.

[0087] In one specific embodiment, such as Figure 3 As shown, the lower part of the sealing ring 3 has a fourth extension 32 extending radially inward. Along the height direction of the liquid heating container, the fourth extension 32 extends between the first extension 411 and the third extension 432. Along the height direction of the liquid heating container, one end of the fourth extension 32 abuts against the first extension 411 and the other end abuts against the third extension 432. Thus, the fourth extension 32 blocks the gap between the first extension 411 and the third extension 432, preventing liquid from entering the receiving cavity 4111 of the first extension 411. This prevents liquid from entering the cavity formed by the bottom cover 22 and the heating assembly 4 from the first receiving cavity 4111, thus preventing damage to the circuit or assembly.

[0088] In this embodiment, during the assembly of the kettle body assembly 2, the mounting part 42 is welded to the heating plate 41 as a whole, the sealing ring 3 is fitted onto the outside of the first extension 411, the bracket 43 is placed under the first extension 411, and the bracket 43 is connected to the mounting part 42 by screws to form the heating assembly 4. The sealing ring 3 and the heating assembly 4 are pushed upward from the lower opening of the container body 21 until the buckle 4321 engages with the first slot 211, and then the bottom cover 22 is fastened from the lower part of the container body 21 through the second slot 212 to complete the installation.

[0089] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
