[0004] When the above application places the power supply body inside the shell structure, it can be placed directly on the placement station of the power supply placement layer, and the guide placement rod plays a guiding role during placement, so that the power supply body can be placed quickly and accurately. After placement, it is clamped and positioned by the clamping parts, that is, the power supply body is firmly placed at the position of the placement station through the clamping parts to avoid its position movement. This structure can achieve the purpose of fast and accurate placement and fast disassembly. However, most of the current embedded power supplies are protected by a shell, and the overall device uses a built-in fan for active heat dissipation or slotted passive heat dissipation. However, dust can easily settle into the interior of the power supply, affecting the reliability of use. Therefore, the market urgently needs to develop an elevator embedded power supply to help people solve the existing problems. Utility Model Content

[0011] Through the above technical solution, the first filter and the second filter can further prevent dust from entering the embedded power supply.

[0012] In a preferred example, the utility model can be further configured as follows: a baffle is arranged inside the dust shield cover to form a ventilation duct.

[0013] Through the above technical solution, the ventilation duct is used to input external air into the embedded power supply, and then the heat inside the embedded power supply is output.

[0014] In a preferred example, the present invention can be further configured as follows: feet are provided on both sides of the power supply housing, and mounting holes are provided on the feet.
