Small household appliances are widely used in people's daily life, improving the quality of life, including but not limited to personal life, nursing, health small household appliances, household small household appliances, kitchen and dining small household appliances, and bathroom small household appliances.

[0003] The existing small household appliances are small in size, and many double-layer circuit boards of small household appliances are spliced by multiple pieces stacked vertically, so as to reduce the planar area and avoid increasing the size of small household appliances. When the existing small household appliances are spliced by multiple layers, the applicant finds that the existing double-layer circuit boards are directly fixed together with bolts, and a spacer is arranged in the middle to ensure the fixed distance. However, when the double-sided circuit board in the middle area needs to be disassembled, the other circuit boards need to be disassembled first, and then the double-sided circuit board in the middle area can be disassembled. It is impossible to disassemble and assemble any one layer of circuit board separately. At the same time, the circuit boards are connected by connecting cables, and the cables between the circuit boards are messy. When disassembling and assembling, the connecting cables need to be disassembled and assembled one by one, which is very troublesome. In order to solve the above problems, a spliced small household appliance multilayer double-sided circuit board is provided. SUMMARY
