The one-way ring 65 of the present invention is prior art.

The engagement between the limiting block 15 and the corresponding limiting groove a19 in the present invention keeps the opening state of the sash 11 and the window frame 5, and can be released by pulling the chain 22 with a large force.

The cooperation of the inner block 31 and the limiting groove B36 of the corresponding arc block B35 keeps the closing state of the casement 11 and the window frame 5, and the cooperation of the inner block 31 and the limiting groove B36 of the corresponding arc block B35 can be released under the driving of pulling the chain 22 with large force.

The working process of the invention is as follows: in the initial state, the opening sash 11 is closed with the window frame 5, and the opening sash 11 is in sealing engagement with the seal ring 9 mounted on the window frame 5. One end of each of the two limit blocks 15 is respectively in contact fit with the inner part of the corresponding arc block A18, and the two limit springs A17 are in a compressed energy storage state. One end of the inner block 31 on the two telescopic blocks is respectively inserted into the limit groove B36 on the inner wall of the corresponding arc block B35, incomplete limit is formed on the relative position of the opening sash 11 and the window frame 5, and the closing state of the opening sash 11 to the skylight opening 2 is kept. The two pneumatic rods 25 are retracted to the shortest. The two fan-folded side barrier films 39 are respectively folded back and recovered into the two accommodating grooves a 7. The window screen 40 is wound around the roller D54 through the roller a10, between the roller B48 and the roller C49, and between the two dust brushes 52. Scroll spring A51, scroll spring B56 and scroll spring C60 are all in a pre-compressed energy storage state. The window screen 40 is in a taut state. The ratchets on the two swing rods 58 are respectively meshed with the two ratchets 57. And the limiting spring A17 and the limiting spring B34 are both in a compression energy storage state. The two shift levers 37 respectively interact with the two swing rods 58, and the ratchets on the two swing rods 58 are respectively separated from the two ratchet wheels 57.

When the skylight needs to be opened, firstly, a chain 22 hung in a room is pulled by hand, the chain 22 drives the chain wheel 21 to rotate, the chain wheel 21 drives the limit round block 13 to rotate synchronously through the shaft B20, the limit round block 13 drives the fan opening 11 to swing upwards around the central axis of the shaft A12 through the corresponding shaft A12, and the fan opening 11 drives the other limit round block 13 to rotate synchronously through the other shaft A12. The fan 11 drives the two pneumatic rods 25 to extend through the two fixed blocks 26 and swing upward around the hinge points with the corresponding U-shaped seats 24. The two limiting round blocks 13 respectively rotate relative to the corresponding arc blocks A18 at the same time, the limiting inclined planes B32 on the inner blocks 31 in the two telescopic blocks interact with the notch edges of the corresponding limiting grooves B36, the two inner blocks 31 respectively retract and slide towards the corresponding sliding sleeves 29 at the same time, the two limiting springs B34 are further compressed to store energy at the same time, and the inner blocks 31 remove the limitation of the relative positions of the oppositely opened sash 11 and the window frame 5. When the inner blocks 31 of the two telescopic blocks are respectively separated from the corresponding arc blocks B35, the inner blocks 31 of the telescopic blocks respectively slide outwards the sliding sleeve 29 to the limit length under the action of the corresponding limit springs B34. The two shift levers 37 are respectively separated from the two swing rods 58, the two swing rods 58 respectively swing under the action of corresponding scroll springs C60, and ratchets on the two swing rods 58 are respectively meshed with the two ratchet wheels 57.

The window screen 40 and the two side barrier films 39 are pulled upwards by the opening sash 11 which is opened around the central axis of the shaft A12, the two side barrier films 39 are unfolded simultaneously, the tightened window screen 40 drives the roller A10, the roller B48 and the roller C49 to rotate, the window screen 40 pulls the roller C49 and the roller D54 to rotate, the roller D54 releases the window screen 40 wound on the roller, and the two scroll springs A51 are further compressed to store energy. Since the ratchets on the swing link 58 do not limit the rotation of the ratchet wheel 57, the roller D54 drives the two ratchet wheels 57 and the two pulleys a62 to rotate synchronously through the shaft D55, and the two spiral springs B56 are further compressed and stored energy simultaneously. The two ratchets 57 which rotate respectively drive the two swing rods 58 to repeatedly swing at high frequency around the corresponding shafts E61. The two belt wheels A62 drive the belt wheel B64 on the same side to rotate through corresponding synchronous belts A63. At this time, since the one-way ring 65 performs an overrunning function, the pulley B64 does not rotate the shaft F66 by the one-way ring 65, and the shaft F66 does not rotate the two fans 74 by the pulley C69, the timing belt B70, the pulley D71, and the shaft G72. In the process of opening the sash 11, the brush ends of the two dust removing brushes 52 are inclined towards the roller C49 wound around the window screening 40, so that the brush ends of the two dust removing brushes 52 do not clean the window screening 40 or the cleaning effect is weak, and no dust or a little dust enters the window sash.

When the fan 11 is completely opened to the horizontal position, the two limit blocks 15 just face the limit grooves A19 on the inner wall of the corresponding arc block A18 and enter the corresponding limit grooves A19 under the action of the corresponding limit springs A17, so that incomplete limit is formed on the fan 11 in the horizontal state. The two pneumatic rods 25 are extended to the longest and form an auxiliary support for the opened fan 11. At this time, the two side blocking films 39 are completely unfolded and vertically tightened, and the two side blocking films 39 and the pulled window screen 40 form a closed space into which mosquitoes can enter.

When the skylight needs to be closed, the chain 22 is pulled reversely by force, the chain 22 drives the chain wheel 21 to rotate reversely, the chain wheel 21 drives the limit round block 13 to rotate reversely synchronously through the shaft B20, and the limit round block 13 drives the fan 11, the other shaft A12 and the other limit round block 13 to rotate and swing synchronously through the corresponding shaft A12. The limit-releasing inclined planes A16 on the two limit blocks 15 interact with the notch edges of the limit grooves A19, the two limit blocks 15 simultaneously contract inwards the corresponding sliding grooves 14 and release the limit of downward swing of the opening fan 11 around the shaft A12, and the two limit springs A17 are further compressed to store energy. The two pneumatic rods 25 are compressed by the fan 11 and swing down around the hinge point with the corresponding U-shaped seat 24, and the two inner blocks 31 on the telescopic blocks gradually approach the two arc blocks B35. At the same time, the two side barrier films 39 begin to fold back and begin to retract into the respective receiving grooves a7, and the window screen 40 begins to relax. Roller C49, which is mounted on shaft C50, rotates in the opposite direction by the return action of two wrap springs a51 and transports the window screen 40 in the direction of the dust brush 52 together with roller B48. Since the two ratchet wheels 57 are restricted from rotating in opposite directions by the ratchets of the two swing rods 58, the two scroll springs B56 do not drive the roller D54 to wind the window screen 40 through the shaft D55. The window screening 40 is piled up between the dust removing brush 52 and the roller C49, the window screening 40 and the dust removing brush 52 do not move relatively, the dust removing brush 52 does not remove dust on the window screening 40, and the dust on the window screening 40 brushed down by the dust removing brush 52 in the process of opening the window 11 and closing the skylight 2 is prevented from entering the room to pollute the air in the room.

When the opening fan 11 is completely closed, the inner blocks 31 on the two telescopic blocks respectively enter the inner walls of the corresponding arc blocks B35 and are respectively just opposite to the limiting grooves B36 on the corresponding arc blocks B35. Under the reset action of the corresponding limiting spring B34, the inner blocks 31 on the two telescopic blocks respectively and rapidly enter the limiting grooves B36 on the corresponding arc blocks B35 and form incomplete limitation on the relative positions of the sash 11 and the window frame 5 in a closed state, the sash in a sealed closed state is prevented from loosening under the treading of wind power or flying birds, and the sash 11 is ensured to be always closed on the skylight opening 2. At this time, the ends of the two limit blocks 15 are respectively in contact fit with the inner walls of the corresponding arc blocks a 18.

Meanwhile, the two shift levers 37 mounted on the fan opening 11 interact with one ends of the two swing rods 58 respectively, and drive the two swing rods 58 to swing around the corresponding shafts E61 respectively, the ratchet wheels 57 on the two swing rods 58 are disengaged from the two ratchet wheels 57 respectively, the reverse rotation limitation on the ratchet wheels 57 is removed, and the two volute spiral springs C60 are compressed again to store energy. The roller D54 mounted on the shaft D55 is rotated by the two wrap springs B56 and winds the window screen 40 accumulated between the dust removing brush 52 and the roller C49. Since the brush tip ends of the two dust removing brushes 52 are inclined toward the roller C49 around the window screen 40, the two dust removing brushes 52 brush off the dust on the window screen 40 passing therebetween, and the dust brushed off the window screen 40 flies into the housing 42. Since the opening fan 11 is completely closed at this time, the flying dust does not enter the room through the sunroof 2.

Meanwhile, the shaft D55 drives the two pulleys a62 to rotate in opposite directions, and the two pulleys a62 drive the corresponding pulleys B64 to rotate through the corresponding timing belts a 63. Since the one-way ring 65 performs a one-way driving function at this time, the two pulleys B64 drive the flywheel 68 and the pulley C69 on the same side to rotate synchronously through the corresponding one-way ring 65 and the corresponding shaft F66, respectively. The two belt wheels C69 drive the corresponding belt wheel D71 to rotate through the synchronous belt B70 on the same side, and the belt wheel D71 drives the fan 74 on the same side to rotate rapidly through the corresponding shaft G72. The two fans 74 simultaneously discharge the dust flying in the casing 42 through the two dust discharge ports 45, thereby preventing the dust from accumulating in the casing 42. After the rotation of the shaft D55 is stopped, since the one-way ring 65 now performs the overrunning function, the two flywheels 68 drive the shaft F66 to continue to rotate, the flywheels 68 gradually decelerate and finally stop, and the two fans 74 stop as the flywheels 68 stop.

After a period of use, some dust may accumulate in the housing 42. Water is sprayed into the housing 42 through the water inlet 43, and the water sprayed into the housing 42 washes a small amount of dust accumulated in the housing 42 and is discharged through the water outlet groove 44.

In conclusion, the beneficial effects of the invention are as follows: in the process of opening the skylight opening 2, the window opening pulls out the window screen 40 wound on the roller D54 and forms a closed space with the two side barrier films 39 to play a role in preventing mosquitoes.

In addition, the dust removing mechanism 41 does not remove dust from the window screening 40 in the process of opening and closing the skylight opening 2, the dust removing mechanism 41 removes dust from the window screening 40 accumulated between the roller C49 and the dust removing brush 52 only after the skylight opening 2 is completely closed, and the dust on the window screening 40 is prevented from flying up due to being brushed off by the dust removing brush 52 and entering the room through the window screening 40 in the process of closing the skylight opening 2. During the process of removing dust from the window screen 40 by the two dust removing brushes 52, the two energy-storing volute spiral springs B56 drive the roller D54 to wind and recover the window screen 40 through the shaft D55.

At the same time, the shaft D55 drives the two fans 74 through a series of transmissions to discharge the dust falling from the window screen 40 to the outside, preventing the dust in the housing 42 from accumulating.
