Description

Technical Field

[0001] This utility model relates to the field of liquid heater technology, and in particular to a heating plate mounting structure for a liquid heater. Background Technology

[0002] The patent application published by the same applicant in earlier application, with publication number CN223311032U, discloses a liquid heater, including a pot body and a heating plate. A fixing component is provided below the heating plate. The fixing component is used to support the heating plate and is fixedly connected to the bottom of the pot body. The fixing component includes a fixing frame and a support. The fixing frame has a through-hole in the middle and is sleeved on the outside of the support. The support is supported below the heating plate. The support includes an integrally formed support part and a connecting part. The top of the support part abuts against a washer. The connecting part is fixedly connected to the fixing frame by screws.

[0003] In order to make the heating plate make better contact with the bottom of the kettle, the above-mentioned patent will also add a spring in actual production. The spring is placed between the heating plate and the fixing component. Through the elastic force of the spring, the heating plate is made to adhere to the bottom of the kettle, thereby improving the heat transfer efficiency.

[0004] However, the lack of a positioning structure in the spring installation makes it prone to tilting, fatigue, and uneven force distribution during actual installation. Utility Model Content

[0007] As a further improvement to the above technical solution, a first fixing ring is integrally provided on the side of the heating plate, and a first through hole is provided on the first fixing ring. The first through hole is sleeved on the fixing post; the spring is installed below the first fixing ring, and the two ends of the spring abut against the first fixing ring and the limiting member, respectively.

[0008] As a further improvement to the above technical solution, a screw hole is provided at the lower end of the fixing column, and the limiting member is a screw, which is screwed onto the fixing column; the screw has a nut, the diameter of which is larger than the diameter of the spring, and the spring abuts against the nut.

[0009] As a further improvement to the above technical solution, the limiting component is integrally disposed on the fixed column.

[0010] As a further improvement to the above technical solution, a bottom shell is also included, which is fixedly installed at the bottom of the kettle body and covers the bracket and heating plate.

[0011] As a further improvement to the above technical solution, an annular groove is provided on the lower side of the bracket, one end of the fixing column is integrally connected to the bottom surface of the annular groove, and the other end of the fixing column extends downward.

[0012] The beneficial effects of this utility model are: by setting several fixed columns on the bracket and sleeve the spring on the fixed columns, the spring is not easy to tilt or fatigue, and the spring is evenly stressed. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Reference Figures 1 to 4 A heating plate mounting structure for a liquid heater includes a pot body 1 and a heating plate 3. A bracket 2 is fixedly mounted on the pot body 1. The top surface of the heating plate 3 contacts the bottom surface of the pot body 1. The bracket 2 is annular and surrounds the outer periphery of the heating plate 3. Several fixing posts 21 are provided on the bracket 2, extending downward. A spring 6 is sleeved on the fixing post 21. A limiting member 4 is fixedly connected to the lower end of the fixing post 21. The limiting member 4 is used to abut against the lower end of the spring 6. The lower end of the spring 6 abuts against the limiting member 4. The heating plate 3 abuts against the upper part of the spring 6. The setting of the fixing posts 21 enables the spring 6 to be positioned, preventing the spring 6 from tilting or shifting during installation, thereby ensuring that the spring 6 is subjected to uniform force and is not prone to fatigue. It should be noted that the spring in the above-mentioned "heating plate 3 abuts against the upper part of the spring 6" can be in direct contact with the heating plate 3 or indirect contact with the heating plate 3 (i.e., there is a component such as a partition between the two). Both direct and indirect contact fall within the concept of "heating plate 3 abuts against the upper part of the spring 6".

[0020] Specifically, the fixing post 21 and the spring 6 are evenly spaced around the bottom of the pot body 1. The spring 6 plays a role in relieving and balancing the stress at the bottom of the pot body 1, so that the stress at the bottom of the pot body 1 is uniform, and the pot body 1 is prevented from cracking due to uneven force and heat conduction.

[0021] In other embodiments, a first fixing ring 31 is integrally provided on the side of the heating plate 3, and a first through hole 311 is provided on the first fixing ring 311. The first through hole 311 is sleeved on the fixing post 21; the spring 6 is installed below the first fixing ring 31, and the two ends of the spring 6 abut against the first fixing ring 31 and the limiting member 4 respectively.

[0022] In a preferred embodiment, the lower end of the fixing post 21 is provided with a screw hole, and the limiting member 4 is a screw, which is screwed onto the fixing post 21; the screw has a nut, the diameter of which is larger than the diameter of the spring 6, and the spring 6 abuts against the nut. The elastic force of the spring 6 can be adjusted by rotating the screw.

[0023] In other embodiments, the above-mentioned screw solution can be replaced by: the limiting member 4 is integrally disposed on the fixing post 21, and the limiting member 4 only serves as a component for limiting the spring 6.

[0024] In some embodiments, a bottom shell 7 is further included, which is fixedly installed at the bottom of the kettle body 1 and encloses the support 2 and the heating plate 3, thereby forming a closed heating cavity.

[0025] In some embodiments, the lower side of the bracket 2 is provided with an annular groove 22, one end of the fixing post 21 is integrally connected to the bottom surface of the annular groove 22, and the other end of the fixing post 21 extends downward.

[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
