Description

Technical Field

[0001] The utility model relates to a mechanical resetting device. Background Art

[0002] In the prior art, for example, in an electric kettle, a user presses a switch button and the electric kettle starts to boil water. When the water temperature in the electric kettle reaches the boiling temperature, the thermostat disconnects the power supply of the heating module and the electric kettle stops heating. The electric kettle has a single function. In the prior art, if the user needs to continue boiling water, he needs to wait for the thermostat to automatically reset before heating can be started again, which cannot meet the needs of the user.

[0003] Since the electric kettle is a cooking utensil, in principle, the electric kettle can perform the hot pot function, but this function requires that the water in the electric kettle be kept boiling. However, in the prior art, since the user cannot manually reset the thermostat, it is necessary to wait for the thermostat to automatically reset after natural cooling before continuing to heat, which cannot meet user needs.

[0004] There is also a cooking utensil in the prior art that can control the thermostat to reset, but its thermostat is placed horizontally, resulting in the need to add a heat conductive sheet between the temperature sensing surface of the thermostat and the heating plate for heat transfer. This method has poor temperature sensing effect and is not accurate. Utility Model Content

[0027] Overall, this design further enhances the connection stability, ease of installation and mechanical durability of the mechanical reset device, making it more suitable for practical applications and improving the reliability of the entire system.

[0028] Furthermore, it also includes a thermostat, wherein the thermostat is provided with a control rod for resetting, and the control rod extends downward and rests on the control part.

[0029] Direct control: The thermostat's control lever is in direct contact with the control part of the mechanical reset device. Such a direct connection may increase the sensitivity and accuracy of the control, thereby more effectively resetting the thermostat.

[0030] No additional transmission mechanism required: Since the joystick is in direct contact with the control part, no additional transmission mechanism or connecting parts may be required. This helps to simplify the system structure, reduce potential failure points, and improve the stability of the system.

[0031] Real-time response: A joystick that directly contacts the control unit may achieve a more real-time response. This means that when the thermostat needs to be reset, the operation of the mechanical reset device can be triggered more quickly, improving the dynamic performance of the system.

[0032] Reduce energy consumption: Since no additional transmission mechanism is required, the loss of energy transmission may be reduced, thereby improving the energy efficiency of the system.

[0036] Operation control: The first button and the second button are connected to the corresponding switch, and the corresponding switch is controlled to be turned on or off by the activity of the button. This provides an additional operation control means, which can be used to adjust the working state of the system or respond to specific needs.

[0037] Functional expansion: The existence of the first switch and the second switch enables the mechanical reset device to have more functional expansion possibilities. By controlling the state of the switch, different working modes of the system can be realized or special operations can be performed.

When the reset button is pressed, the reset button overcomes the elastic force of the spring and pushes the push rod to move. During the movement of the push rod, the control rod moves upward under the action of the control part, completing the reset of the thermostat and the heating plate continues to work.

[0044] Precise temperature control: The temperature sensing surface of the thermostat is close to the bottom wall of the heating plate, which can accurately sense the temperature of the heating plate. The mechanical reset device can accurately reset the thermostat by moving the control rod, thereby ensuring the accuracy of the temperature control of the system.

[0045] Temperature sensing design without heat conducting sheet: In the prior art, the thermostat is placed horizontally, which requires an additional heat conducting sheet to transfer heat between the temperature sensing surface of the thermostat and the heating plate. This method has poor temperature sensing effect and is not accurate. The utility model does not require additional heat conducting sheet, which makes the temperature sensing effect of the thermostat better, reduces manufacturing costs, and simplifies the design of the temperature sensing part.

[0046] Simplified operation: The reset button design simplifies the operation process. Users only need to press the reset button to reset the thermostat. This design increases user-friendliness and reduces the complexity of use.

[0063] Uniform heat distribution: The different designs of the heating tube and PCT heating element may result in different heat distribution characteristics. By using both heating modules in the system, a more uniform heat distribution can be achieved, thus improving the cooking quality of the food.
