[0023] To make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-4 As shown, this utility model provides a weighing automatic water supply base, including a base housing 1. Two floating foot pads 2 are movably inserted through the bottom of the base housing 1. The tops of the two floating foot pads 2 are respectively fixed to the two ends of a connecting rod 3. The connecting rod 3 is located inside the base housing 1. A weighing sensor 4 is provided above the middle part of the connecting rod 3. The end of the weighing sensor 4 is fixed inside the base housing 1. An electronic control component is provided inside the base housing 1. The electronic control component and the weighing sensor 4 are electrically connected.

[0025] Two floating feet 2 serve as two support points, and the two-point support connecting rod 3 is used to move. The weighing sensor 4 is set inside the base housing 1. When water is poured into the electric kettle 15, as the weight increases, the pressure of the floating feet 2 on the weighing sensor 4 gradually increases. The pressure generated by the floating feet 2 is transmitted to the weighing sensor 4, and the pressure information is converted into water volume information, so as to achieve accurate control of the water volume.

[0026] Two fixed feet 5 are also fixed to the bottom of the base housing 1. The two fixed feet 5 are located on one side of the bottom of the base housing 1, and the two floating feet 2 are located on the other side of the bottom of the base housing 1.

[0027] Two fixed foot pads 5 serve as fixed supports, preventing movement and deformation. Only two floating foot pads 2, together with the connecting rod 3, act on one weighing sensor 4. Only one weighing sensor 4 needs to be fixed inside the base housing 1 to realize the conversion between pressure deformation and water capacity. The structure is simple and can reduce costs.

[0028] The bottom of the base housing 1 has two through holes 6, the diameter of which is larger than the diameter of the floating feet 2. The two floating feet 2 are respectively inserted into the two through holes 6. The through holes 6 facilitate the up and down movement of the floating feet 2.

[0029] The base housing 1 has a boss 7 inside, and one end of the load cell 4 is fixed to the boss 7 by a locking assembly. The locking assembly includes a pressure plate 8 and a screw 9. The pressure plate 8 presses against the end of the load cell 4, and the screw 9 passes through the pressure plate 8 and is screwed into the boss 7. Only one end of the load cell 4 needs to be fixed, which is simple in structure and easy to assemble.

[0030] A coupler 10 is fixedly mounted on the top of the base housing 1, and the coupler 10 is electrically connected to the electronic control component. The coupler 10 cooperates with the heating component at the bottom of the electric kettle 15 to heat the water.

[0031] A water pump 11 is installed inside the base housing 1. The water pump 11 has an inlet pipe and an outlet pipe connected to its two ends, respectively. The inlet pipe extends out of the base housing 1 and is used to connect to an external water source. The outlet pipe extends into the middle of the coupler 10 and is used to supply water to the electric kettle 15. The water pump 11 draws water from the external water source through the inlet pipe to the outlet pipe, and then into the electric kettle 15. Combined with the weighing sensor 4, this controls the amount of water injected.

[0032] A protruding guide rod 12 is fixed above the middle of the connecting rod 3. The load cell 4 has a guide hole 13, and the guide rod 12 is inserted into the guide hole 13. The guide rod 12 and the guide hole 13 cooperate to realize the accurate pressure sensing of the load cell 4 by the connecting rod 3.

[0033] An operation panel 14 is fixed on the base housing 1, and the operation panel 14 is electrically connected to the electronic control components.

[0034] The base housing 1 includes a bottom cover 101 and an upper cover 102, with the upper cover 102 fixedly covering the bottom cover 101.

[0035] This invention uses only one weighing sensor 4, which is located inside the base housing 1. Two floating feet 2 are connected to the weighing sensor 4 via a connecting rod 3. The two floating feet 2, together with the connecting rod 3, act as a fulcrum to provide stability. The electronic control components are located inside the base housing 1, which can effectively isolate them from water vapor and the high temperature of the kettle, greatly reducing the risk of failure. The electric kettle 15 is placed on top of the base housing 1, which is compatible with all kettle shapes. The electric connection between the weighing sensor 4 and the electronic control components enables control of the water volume and heating system, preventing overflow due to overfilling. This invention features a simple structure, low cost, and small footprint.
