Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A frequency converter assembly with strong heat dissipation includes a base 1, a frequency converter body 7, and a heat sink 8 installed on the outer wall of the frequency converter body 7. The base 1, the frequency converter body 7, and the heat sink 8 are existing technologies and will not be described in detail here. A second rubber pad is fixedly connected to the lower end of the base 1 to prevent the lower end of the base 1 from being worn. A plurality of vertically arranged pillars 9 are fixedly connected between the lower end of the frequency converter body 7 and the upper end of the base 1. The frequency converter body 7 is located above the base 1.

[0022] In this embodiment, the heat sink 8 is provided with multiple grooves on the side away from the inverter body 7. A lifting box 12 is slidably connected to the inner wall of the groove for driving the brush 13 to rise and fall. The lifting box 12 is provided with through holes communicating with its interior at one end facing the inverter body 7 and at both the front and rear ends for sucking up dust and debris. The lifting box 12 is fixedly connected to the brush 13 at one end facing the inverter body 7 and at both the front and rear ends for cleaning the inner wall of the groove.

[0023] In this embodiment, a lifting block 11 is provided on the side of the heat sink 8 away from the inverter body 7, which is used to drive the lifting box 12 to rise and fall. One end of the lifting box 12 passes through the groove and is fixedly connected to the lifting block 11. Two vertically arranged guide rods 10 are slidably inserted into the upper end of the lifting block 11 to guide the lifting block 11 to rise and fall. The lower end of the guide rod 10 passes through the lifting block 11 and is fixedly connected to the upper end of the base 1. An electric push rod 6 is fixedly connected to the lower end of the lifting block 11 to drive the lifting block 11 to rise and fall. The lower end of the electric push rod 6 is fixedly connected to the upper end of the base 1.

[0024] In this embodiment, a connecting box 3 is fixedly connected to the upper end of the base 1 for storing dust and debris. An exhaust fan 2 connected to the connecting box 3 is fixedly connected to the upper end of the base 1 for drawing airflow. A vertically arranged filter screen 4 is slidably inserted into the inner side wall of the connecting box 3 for filtering dust and debris. A slot corresponding to the filter screen 4 is provided at the bottom of the connecting box 3. The lower end of the filter screen 4 slides into the slot. A cover plate 14 is rotatably connected to the upper end of the connecting box 3 for closing the connecting box 3. A locking screw is provided at the upper end of the cover plate 14 for fixing the cover plate 14. The cover plate 14 is fixed to the connecting box 3 by the locking screw. A telescopic hose 5 is fixedly connected to the lower end of the lifting box 12 for circulating air and dust. The lower end of the telescopic hose 5 passes through the groove and the cover plate 14 and extends into the connecting box 3. The telescopic hose 5 and the cover plate 14 are fixedly connected.

[0025] In this embodiment, a first rubber pad is fixedly connected to the lower end of the cover plate 14 to improve the sealing performance of the cover plate 14. The lower end of the first rubber pad abuts against the upper end of the connecting box 3. A rubber block 15 is fixedly connected to the lower end of the cover plate 14 to press the filter screen plate 4. The lower end of the rubber block 15 extends into the connecting box 3 and abuts against the upper end of the filter screen plate 4. A pull ring is fixedly connected to the upper end of the cover plate 14 to facilitate the user to open the cover plate 14.

[0026] In this embodiment, firstly, the exhaust fan 2 is started. The exhaust fan 2 sucks the dust and debris in the groove of the heat sink 2 into the connecting box 3 through the through hole, the lifting box 12, and the telescopic hose 5. To prevent dust and debris from entering the exhaust fan 2, a filter screen 4 is used to block them. In this way, the cleaning of the heat sink 8 can be carried out smoothly. At the same time, the electric push rod 6 is started to drive the lifting block 11 and the lifting box 12 to move up and down. With the up and down movement of the lifting box 12, the lifting box 12 drives the brush 13 to thoroughly clean the upper, lower, and side walls of the groove, effectively reducing cleaning dead corners. Finally, simply unscrew the locking screw and unscrew the cover plate 14 to easily clean the dust and debris in the connecting box 3. This also makes it convenient for the user to perform necessary maintenance on the filter screen 4.
