Description

Technical Field

[0001] This utility model belongs to the technical field of liquid heaters, specifically relating to a connection structure for a kettle body and a liquid heater having the structure. Background Technology

[0002] As society continues to develop and people's living standards continue to improve, people are paying more and more attention to their own health and cooking nutritious foods in their daily lives. Liquid heaters, such as glass health pots, are very popular because they can cook nutritious foods, boil nutritious soups, and brew nutritious teas.

[0003] In existing glass health pots, the connection structure between the heating plate and the glass body typically uses a mounting bracket, a silicone pad, and a hoop. The installation process is as follows: the heating plate is placed on the bottom surface of the glass body; the silicone pad is fitted onto the outer wall of the glass body; the mounting bracket is fitted over the silicone pad and positioned on the lower side wall of the glass body, pressing the heating plate against the bottom surface; and the hoop is fitted over the outside of the mounting bracket, locking it to the glass body. The problem is that the mounting bracket in this connection structure is generally made of metal and manufactured through stamping, bending, and welding processes. The use of metal results in high material costs for the mounting bracket, and the numerous processing steps lead to high labor costs, thus increasing production costs and reducing the product's market competitiveness. Furthermore, the numerous processing steps extend the manufacturing time, reducing production efficiency.

[0004] Therefore, further improvements are needed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0030] See Figure 1-7 The connecting structure of this kettle body includes a kettle body 11, a kettle shell 12, a heating element 13, and a fixing bracket 15. In this embodiment, the kettle body 11 is preferably made of glass, and the kettle shell 12 is preferably made of plastic. The heating element 13 preferably includes a heating plate, a thermostat, a temperature sensor, etc., and is pressed onto the bottom surface of the kettle body 11 by the fixing bracket 15. The fixing bracket 15 is located at the bottom of the kettle body 11. Specifically, the fixing bracket 15 is preferably made of high-temperature resistant plastic materials such as PI or PPS to improve the durability of the fixing bracket 15. The fixing bracket 15 includes a bracket body 151 and an installation extension 152. The bracket body 151 is ring-shaped and is fitted onto the lower side wall of the kettle body 11 through an installation structure, pressing the heating element 13 onto the bottom surface of the kettle body 11. The installation extension 152 is integrally formed with the bracket body 151 and extends downward from the bottom surface of the bracket body 151. Specifically, the installation extension 152... The bracket includes a first extension and a second extension. The first extension extends downward at an angle from the center of the bracket body 151, and the second extension extends horizontally from the first extension toward the center of the bracket body 151. Preferably, there are four mounting extensions 152 arranged circumferentially at intervals on the bottom surface of the bracket body 151. The second extension of the mounting extension 152 is provided with mounting screw holes. The kettle shell 12 is fastened to the second extension of the mounting extension 152 by screws or other fastening components to achieve the lid being mounted on the bottom of the kettle body 11. Since plastic materials are cheaper than metal materials, the material cost of the fixing bracket 15 is reduced. Moreover, the fixing bracket 15 only needs to be molded to complete the required shape, reducing the processing steps of the fixing bracket 15 and reducing the labor cost of the fixing bracket 15. This reduces the manufacturing cost of the fixing bracket 15, thereby reducing the production cost of the product and improving the product's competitiveness in the market.

[0031] In addition, by adopting the above technical solution for the fixed bracket 15, the processing steps of the fixed bracket 15 are reduced, the manufacturing time of the fixed bracket 15 is reduced, thereby reducing the production time of the product and improving the production efficiency of the product.

[0032] Furthermore, the fixed bracket 15 also includes a bracket reinforcement 153. Specifically, in this embodiment, the vertical projection of the bracket reinforcement 153 is arc-shaped and integrally formed with the bracket body 151. The number of bracket reinforcements 153 is preferably three and they are respectively disposed between two adjacent mounting extensions 152. Through the above technical solutions, the mechanical strength of each mounting extension 152 is improved, the service life of each mounting extension 152 is extended, and the service life of the fixed bracket 15 is improved to a certain extent. This is understandable to those skilled in the art.

[0033] Furthermore, in this embodiment, the mounting structure includes mounting hooks 1510 and mounting slots 111. Specifically, the number of mounting hooks 1510 is preferably three, which are evenly spaced circumferentially on the side wall of the support body 151. The number of mounting slots 111 is preferably one, which is arranged in a ring on the lower part of the side wall of the pot body 11. The mounting hooks 1510 and the mounting slots 111 are correspondingly arranged. When the mounting hooks 1510 extend into the mounting slots 111 and engage with each other, the fixed support 15 is mounted on the pot body 11. This is understood by those skilled in the art.

[0034] Furthermore, in this embodiment, the mounting hook 1510 is elastically disposed on the side wall of the bracket body 151. The kettle body also includes a locking band 16. Specifically, the locking band 16 is preferably a metal band wrapped around the outer wall of the bracket body 151 and corresponding to the mounting hook 1510. When the locking band 16 contracts and its radial dimension gradually decreases, the locking band 16 acts on the mounting hook 1510, locking the mounting hook 1510 in the mounting groove 111. When the locking band 16 relaxes and its radial dimension gradually increases, the locking band 16 moves away from the mounting hook 1510, causing the mounting hook 1510 to loosen from the mounting groove 111. Through the above technical solution, the mounting hook 1510 is prevented from accidentally coming out of the mounting groove 111, ensuring that the fixed bracket 15 is stably installed on the kettle body 11. This is understood by those skilled in the art.

[0035] Furthermore, the fixed bracket 15 also includes a pressing component 154. Specifically, in this embodiment, the pressing component 154 is n-shaped and is made of plate-shaped iron material by stamping. The pressing component 154 is installed on the bottom surface of the bracket body 151 by fastening components, and the number of them is preferably three and they are evenly spaced in the circumference. When the fixed bracket 15 is installed on the kettle body 11, the pressing component 154 acts on the heating element 13 and presses the heating element 13 against the bottom surface of the kettle body 11. Through the above technical solution, the heating element 13 is fixedly installed on the bottom surface of the kettle body 11 by the fixed bracket 15, which can be understood by those skilled in the art.

[0036] Furthermore, the kettle body also includes a lid 17 and a handle 18. Specifically, in this embodiment, the lid 17 is fitted onto the top opening of the kettle body 11 to reduce the risk of foreign objects falling into the inner cavity from the top opening of the kettle body 11, thus ensuring food safety during cooking. The handle 18 is detachably installed on the side of the kettle body. The upper part of the handle 18 is fitted onto the outer wall of the kettle body 11, and the lower part of the handle 18 is fixed to the kettle shell 12 by fastening components, allowing people to take the kettle body out and put it in through the handle 18, avoiding contact with the kettle body 11 and causing burns from high temperatures. This is something that those skilled in the art can understand.

[0037] See Figure 8 This liquid heater includes a heating base 2 and a kettle body. A control component 21 is provided inside the heating base 2. A heating element 13 is electrically connected to the control component 21 via a coupling structure. Specifically, in this embodiment, the control component 21 includes a display operation component, a control board, a power board, etc., and is disposed within the inner cavity of the heating base 2. The coupling structure is disposed between the kettle body and the heating base 2, and includes a first coupling component 19 and a second coupling component 22. The first coupling component 19 is fixed to a fixed bracket 15 by a fastening component and extends downwards from the bottom surface of the kettle shell 12 and is electrically connected to the heating element 13. The second coupling component 22 is fixed inside the heating base 2 by a fastening component and extends upwards from the top surface of the heating base 2 and is electrically connected to the control component 21. When the liquid heater is working, the kettle body is placed on the heating base 2, and the first coupling component 19 and the second coupling component 22 are coupled together, so that the heating element 13 is electrically connected to the control component 21. Through the above technical solution, the control component 21 controls the heating element 13, thereby ensuring the normal operation of the liquid heater. This is understood by those skilled in the art.
