Technical Field

[0001] The present application belongs to the technical field of linear voltage regulators, and specifically relates to a linear voltage regulator. Background Art

[0002] Linear voltage regulator is a very important electronic component that can realize voltage conversion and provide suitable voltage output for the subsequent circuit. It is used to convert unstable input voltage into stable output voltage. It reduces the input voltage to the required output voltage by adjusting its internal circuit elements and maintains the stability of the output voltage when the load changes.

[0003] For example, the application with publication number CN215526493U discloses a linear voltage stabilizer, including a universal wheel, an inner frame, a placement frame, an outer shell and a handle, wherein the inner frame is located on the inner side of the outer shell, the inner frame is fixedly connected to the outer shell by a bracket, the placement frame is located on the inner side of the inner frame, the placement frame is welded and fixed to the inner frame, the universal wheel is located at the bottom end of the outer shell, the handle is located at the top end of the outer shell, and a second bearing is installed on the outer shell; the use is facilitated by the provision of a support plate and a second bevel gear threaded rod, and the support plate can be moved up and down by rotating the provision of the second bevel gear threaded rod, which conveniently solves the problem that the outer shell cannot be fixed when it needs to be fixed after only the universal wheel is installed, and at the same time, the structure is simple, the concealment is good, and the appearance is not affected.

[0004] However, the linear voltage regulator in the application cannot clean the voltage regulator itself. If the voltage regulator is used in an environment with heavy dust, the converted output voltage will be unstable, affecting its safe production. Now, a linear voltage regulator is provided that can clean the surface of the voltage regulator and the inductor element. Utility Model Content
