[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0020] Example:

[0021] like Figure 1 , 2 As shown, the utility model provides a circuit board installation structure of an electric cooking device, including a shell base 11. The shell base 11 serves as the basis of the entire device and provides a stable support and installation platform for other components. An upper cover 12 is arranged above the shell base 11. An inclined surface is arranged at one end of the upper cover 12, so that the buttons are installed at an angle, which is convenient for users to view and adjust the buttons, and also keeps the buttons away from the high-temperature cooking area, which can effectively avoid damage to the buttons caused by high temperature. The upper cover 12 is connected to the shell base 11 to form an installation cavity together, which is used to accommodate and fix key components such as a circuit board 21. The circuit board 21 is arranged in the installation cavity to ensure the normal operation of the electric cooking device. In order to provide stable support and fixation, a plurality of groups of support sheets 31 are also arranged on the shell base 11. The upper end surface of the support sheet 31 is also arranged as an inclined surface, and its inclination angle is adapted to the inclination angle of the upper cover 12, so that the circuit board 21 is installed at an angle; at the same time, the contact area with the circuit board 21 is increased, and the stability of the support is improved. The circuit board 21 is mounted on the inclined surfaces of the plurality of support plates 31, which not only ensures the stable fixation of the circuit board 21, but also provides a strong guarantee for the normal operation of the electric cooking device.

[0022] like Figure 3 As shown, the upper end portion and the lower end portion of the supporting piece 31 are both provided with a limiting clamping plate 34, which can be smoothly installed in place with the circuit board 21; at the same time, a plurality of groups of positioning grooves 22 are opened on the circuit board 21, and the limiting clamping plate 34 is clamped in the positioning groove 22, which ensures the precise positioning between the circuit board 21 and the supporting piece 31, plays a role in limiting the circuit board 21, can avoid the displacement of the position of the circuit board 21, and improves the accuracy and stability of the installation of the circuit board 21.

[0023] Two groups of support blocks 32 are arranged inside the housing base 11, which are located between two groups of support sheets 31 and play a role of stable support. Two groups of support card plates 33 are arranged on the support blocks 32, and the upper end surfaces of the support card plates 33 are parallel to the inclined surfaces of the support sheets 31, forming a stable support surface. The support card plates 33 correspond to the connecting through holes on the circuit board 21. The connecting screws pass through the connecting through holes and are accurately clamped between the two groups of support card plates 33, ensuring a firm connection between the circuit board 21 and the housing base 11. Not only a stable support structure is provided, but also the circuit board 21 can be safely and reliably fixed on the housing base 11, providing a strong guarantee for the normal operation of the electric cooking device. In order to further enhance the structural strength of the support card plate 33, a reinforcing rib is arranged on one side thereof. It can effectively share the pressure of the circuit board 21 on the support card plate 33, improve the stability and reliability of the entire circuit board 21 installation structure, and ensure the safety and stability of the electric cooking device during long-term use.

A power plug is provided at one end of the shell base 11, and one end of the power plug is clamped in the mounting cavity, ensuring the stable connection of the power plug and providing a reliable power supply for the electric cooking device. A start button 14 is also provided on the upper cover 12, so that the user can easily press the button to start the electric cooking device. A plurality of groups of mounting buckles are provided on the bottom surface of the upper cover 12, and the shape and size of the mounting buckles match the mounting base 15 on the shell base 11. The clamping structure between the mounting buckle and the mounting base 15 ensures a firm connection between the upper cover 12 and the shell base 11.

[0025] The specific usage and function of this embodiment are as follows:

[0026] The circuit board 21 is placed on the inclined surface of the multiple groups of support sheets 31 to ensure that there is enough contact area between the circuit board 21 and the support sheets 31 to improve the stability of the support. The circuit board 21 is accurately positioned in the device through the positioning groove 22 and the limit clamping plate 34 to avoid the deviation of the position of the circuit board 21. The control button installed on the circuit board 21 is used to control and adjust the circuit board 21 and switch between different modes. The installation structure of the circuit board 21 of the electric cooking device plays a key role and provides a strong guarantee for the normal operation of the electric cooking device. The multiple groups of positioning grooves 22 on the circuit board 21 cooperate with the support sheets 31 to ensure the accurate positioning and stable fixation of the circuit board 21, avoid the deviation of the position of the circuit board 21, and improve the accuracy and stability of the installation of the circuit board 21. The control button is installed on the circuit board 21, so that the user can easily control and adjust the circuit board 21, realize the switching of different modes, and bring a convenient use experience to the user. The reasonable design and stable performance of the installation structure of the circuit board 21 provide support for the long-term reliable operation of the electric cooking device and ensure the performance of the electric cooking device under various cooking needs.
