[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an easy-to-clean screen door includes a screen door frame 1, within which two symmetrically arranged screen door components are provided; each screen door component includes a screen curtain 2. A drive roller 7 is provided in the middle of the screen door frame 1, and a cleaning chamber 10 is provided in the side wall of the screen door frame 1. A bobbin 5 is provided in the cleaning chamber 10, and a take-up roller 6 is connected to the lower end of the bobbin 5. A connecting wire 3 is wound on the bobbin 5, and the other end of the connecting wire 3 passes through the drive roller 7 and connects to the screen curtain 2. The other end of the screen curtain 2 is wound around the take-up roller 6. The side wall of the screen door frame 1 is open. A cleaning port 9 communicating with the cleaning chamber 10 is provided. An opening door 13 is provided at the cleaning port 9. Two cleaning rollers 11 are provided between the opening door 13 and the winding roller 6. Each of the two cleaning rollers 11 is connected to a connecting gear. One of the cleaning rollers 11 is connected to a cleaning motor. The two connecting gears are meshed and connected for transmission. A recycling box 12 is provided below the cleaning rollers 11. Each of the two drive rollers 7 is provided with a drive gear 16. The two drive gears 16 are meshed and connected for transmission. One of the drive rollers 7 is connected to a drive motor 4.

[0028] When the screen curtain 2 needs to be cleaned, the drive motor 4 is started, which drives the transmission roller 7, the take-up roller 6 and the spool 5 to rotate. The connecting line 3 wound on the spool 5 is unwound from it and passes through the transmission roller 7. The two screen curtains 2 move in opposite directions. The screen curtains 2 are rolled up onto the take-up roller 6 through the cleaning port 9. At the same time, the cleaning motor is started, which drives the two cleaning rollers 11 to clean both sides of the screen curtain 2. The cleaned dust is collected into the recycling box 12.

[0029] Two opening doors 13 are provided at each of the cleaning openings 9. Each opening door 13 is connected to the cleaning opening 9 via a hinge shaft 17. Both hinge shafts 17 are connected to meshing gears 18, which mesh and drive each other. One of the hinge shafts 17 is connected to the spool 5 via a drive belt. When the drive motor 4 controls the drive roller 7 to rotate counterclockwise, the take-up roller 6 and the spool 5 rotate counterclockwise, causing the hinge shaft 17 to rotate and open the opening door 13. The screen curtain 2 in the screen door frame 1 can enter the cleaning chamber 10 through the cleaning opening 9 for cleaning. At this time, the screen curtain 2 can open the space inside the screen door frame 1, allowing people to enter or exit the room through the screen door frame 1. When the drive motor 4 controls the transmission roller 7 to rotate clockwise, the screen curtain 2 can block the space inside the screen door frame 1. The clockwise rotation of the transmission roller 7 drives the take-up roller 6 and the bobbin 5 to rotate clockwise. The hinge shaft 17 rotates to control the opening door 13 to close the cleaning opening 9.

[0030] like Figure 4 , Figure 5As shown, each of the two opening doors 13 has a sliding groove on one side facing each other. A scraper 14 is slidably connected in the sliding groove. The bottom of the sliding groove is connected to the scraper 14 by an elastic spring 15. When the screen curtain 2 passes between the two opening doors 13, the scraper 14 can easily scrape the screen curtain 2 and clean the dust on it.

[0031] like Figure 6 As shown, the edge of the gauze curtain 2 is provided with a binding 8, and multiple connectors 19 are provided on the binding 8. Each connector 19 includes a connecting port 25 respectively provided on two of the bindings 8. The two connecting ports 25 are arranged facing each other. Each connecting port 25 is provided with a first fixed male and female magnetic block 24. The two first fixed male and female magnetic blocks 24 are magnetically attracted to each other. A movable cavity 20 is provided on one side of the connecting port 25. A movable male and female magnetic block 21 is slidably arranged in the movable cavity 20. The two movable male and female magnetic blocks 21 are magnetically attracted to each other. A connecting pipe 23 is connected to the opposite side of the two movable cavities 20. An air outlet pipe is provided on the opposite side of the two movable cavities 20. A one-way valve is provided in the air outlet pipe. The two connecting pipes 23 are connected to the two connecting ports 25 respectively. A connecting spring 22 is connected to the opposite side of the two movable male and female magnetic blocks 21. The other end of the connecting spring 22 is connected to the movable cavity 20. When the two edging blocks 8 approach each other, the two first fixed male and female magnetic blocks 24 are magnetically attracted to each other. In addition, the two movable male and female magnetic blocks 21 are magnetically attracted to each other. The movable male and female magnetic blocks 21 move in the movable cavity 20, drawing air from the connecting tube 23 into the movable cavity 20. The closer the two movable male and female magnetic blocks 21 are, the tighter the connection between the two edging blocks 8 becomes. Furthermore, the negative pressure state of the connecting tube 23 further makes the connection between the two edging blocks 8 tighter.

[0032] The movable cavity 20 is provided with a slide rail, and the movable male and female magnetic blocks 21 are provided with a slider that is slidably connected to the slide rail.

[0033] Each of the two facing edges 8 has an air inlet, which is connected to a suction fan via an air inlet duct 27. A screen 30 is installed inside the air inlet duct 27, and a recycling pipe 31 connected to the recycling box 12 is installed below one side of the screen 30. The recycling pipe 31 is located between the screen 30 and the air inlet. When the suction fan is activated, the air between the two screen curtains 2 can enter the air inlet duct 27, and dust and other particles can enter the recycling box 12 through the recycling pipe 31. This reduces the amount of dust and other particles entering and leaving the room through the screen door frame 1, thus improving the dustproof effect.

[0034] The air inlet duct 27 is connected to a rubber cavity 28 in the middle. Two second fixing magnetic blocks 29 are provided on both sides of the rubber cavity 28. The two second fixing magnetic blocks 29 are like-pairs and repel each other. A pressure sensor 26 and a pressure plate are respectively provided on the side of the two second fixing magnetic blocks 29 facing each other. The suction fan is connected to the normally closed contact of the pressure sensor 26, or the normally closed contact of the pressure sensor 26 is coupled in the suction fan's circuit. When the two edgings 8 are attached together, the two air inlets are connected. The suction fan starts, reducing the air in the air inlet duct 27. The pressure sensor 26 contacts the pressure plate, opening the normally closed contact of the pressure sensor 26, de-energizing the suction fan. The two edgings 8 are tightly attached together, facilitating the reduction of dust and other contaminants entering and exiting the room through the screen door frame 1, thus improving the dustproof effect.

[0035] Both air inlets are provided with a third fixing male and female magnetic block 32, and the two third fixing male and female magnetic blocks 32 are engaged and snapped together.

[0036] The cleaning roller 11 is provided with a dust suction port, which is connected to the vacuum cleaner through a dust suction pipe. The dust suction pipe is connected to the recycling box 12, and the vacuum cleaner is located inside the cleaning chamber 10.

[0037] Multiple sets of ferromagnetic blocks and permanent magnets are respectively provided on one side of the two edging 8 facing each other. When the two edging 8 come into contact with each other, they can be attracted and connected together, reducing the flow of dust in the frame space inside the screen door frame 1.
