A first piston 8 is fixed to the rear side of the second gear 7. A first oil cylinder 9 is fixed to the top of the first slide rail 2. The first piston 8 is rotatably connected in the first oil cylinder 9. The rotation of the lead screw 4 can drive the rotation of the first gear 6, thereby driving the rotation of the second gear 7. The first piston 8 rotates in the first oil cylinder 9, which is convenient for automatically pressing out the hydraulic oil in the first oil cylinder 9.

[0036] In this embodiment, as Figure 2 , Figure 5 , Figure 6 and Figure 7As shown in the figure, a dust suction channel 1603 is fixed to the inner top of the moving seat 1602, and a second motor 1604 is fixed to the rear side of the dust suction channel 1603.

[0037] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a rotating shaft 1609 is fixed to the worm gear 1608, and the rotating shaft 1609 penetrates through the worm gear 1608 and the dust suction channel 1603. Third gears 1610 are symmetrically fixed to both ends of the rotating shaft 1609. A tooth groove is fixed to the inner bottom of the second slide rail 1601. The third gears 1610 are meshed and connected in the tooth groove. The rotation of the worm gear 1608 drives the rotation of the rotating shaft 1609, thereby driving the rotation of the two third gears 1610. Since the third gears 1610 are meshed and connected with the tooth groove, the third gears 1610 can roll in the second slide rail 1601.

A ratchet sleeve 1613 is sleeved outside the ratchet wheel 1612, and an exhaust fan 1614 is fixed to the top of the ratchet sleeve 1613. The exhaust fan 1614 is rotatably connected to the inside of the dust suction channel 1603. The rotation of the worm 1606 can drive the operation of the second belt transmission assembly 1611, thereby driving the rotation of the ratchet wheel 1612. The rotation of the ratchet wheel 1612 can drive the rotation of the ratchet sleeve 1613, thereby driving the rotation of the exhaust fan 1614. The dust suction channel 1603 sucks dust downward, and the reverse rotation of the ratchet wheel 1612 cannot drive the rotation of the ratchet sleeve 1613.

[0039] In this embodiment, as Figure 5 and Figure 6 shown, a dust collection net 1615 is fixed to the inside of the dust suction channel 1603, and an opening 1616 is formed in the side surface of the dust suction channel 1603. When the dust suction channel 1603 sucks dust, the dust will adhere to the dust collection net 1615, which is convenient for centralized collection.

Both ends of the dust suction pipe 1617 are respectively fixed to two scraping frames 1618. When using the scraping frames 1618 to scrape dust, the dust suction pipe 1617 will suck the dust into the dust suction channel 1603.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 11 shown, a second oil cylinder 1619 is fixed to the inner top of the moving seat 1602, and the second oil cylinder 1619 is connected to the first oil cylinder 9 through a connecting pipe 1620. A second piston 1621 is rotatably connected inside the second oil cylinder 1619, and a sealing ring 1622 is fixed to the bottom of the second piston 1621. The connecting pipe 1620 serves to connect the second oil cylinder 1619 and the first oil cylinder 9. When the first piston 8 rotates and presses the first oil cylinder 9 into the second oil cylinder 1619, the second piston 1621 rotates under the action of oil pressure, thereby driving the sealing ring 1622 to rotate, which is convenient for using the sealing ring 1622 to seal the opening 1616 or using the sealing ring 1622 to scrape the dust on the dust collecting net 1615.

[0042] The usage method and advantages of the present invention: For this self-cleaning air conditioner fin, the working process is as follows:

[0043] As Figures 1 to 11As shown in the figure: First, connect the first refrigeration pipeline 11 and the second refrigeration pipeline 14 to the refrigerant tank and the liquid pump respectively. The refrigerant circulates in the first refrigeration pipeline 11 and the second refrigeration pipeline 14 to cool and dissipate heat from the first fin group 10 and the second fin group 13. If it is necessary to clean the first fin group 10 and the second fin group 13, the screw rod 4 rotates to drive the moving plate 5 to slide forward. The first fin group 10 and the second fin group 13 are respectively inserted into the gaps of each other, so as to automatically push out the dust. The dust accumulates outside the first fin group 10 and outside the second fin group 13. At the same time, the screw rod 4 rotates to drive the first gear 6 to rotate, thereby driving the second gear 7 and the first piston 8 to rotate. The second piston 1621 rotates under the action of oil pressure, and the sealing ring 1622 screws into the dust suction channel 1603 and seals the opening 1616. Then the first belt drive assembly 1605 operates to drive the worm 1606 to rotate, and the worm gear 1608, the rotating shaft 1609 and the two third gears 1610 rotate. The third gear 1610 is meshed and connected to the inner bottom of the second slide rail 1601. The moving seat 1602 slides to the left, and the two scraping frames 1618 respectively scrape the dust on the first fin group 10 and the dust on the second fin group 13. The dust is concentrated in the scraping frames 1618. At the same time, the worm 1606 rotates to drive the second belt drive assembly 1611 to rotate, the ratchet wheel 1612 rotates to drive the ratchet sleeve 1613 and the exhaust fan 1614 to rotate, the exhaust fan 1614 sucks air downward, and the dust suction pipeline 1617 sucks the dust in the scraping frames 1618 into the dust suction channel 1603. The dust adheres to the dust collection net 1615. Then the two scraping frames 1618 move to the right together with the moving seat 1602, and the ratchet wheel 1612 rotates back without driving the ratchet sleeve 1613 and the exhaust fan 1614 to rotate. Then the moving plate 5 moves backward, and the first fin group 10 is separated from the second fin group 13. At the same time, the sealing ring 1622 rotates back and automatically scrapes the dust on the dust collection net 1615. The staff can use the collection device to collect the dust for processing.

[0044] In summary, the self-cleaning air-conditioning fins achieve the purpose of automatically scraping and sucking dust and automatically removing dust, meeting people's usage requirements.
