As shown in fig. 17, 18 and 27, the transmission ratio of the pulley a55 to the pulley B57 is smaller than 1, the transmission ratio of the pulley C62 to the pulley D64 is larger than 1, when the chain B54 is pulled to drive the sprocket B53 to rotate, the sprocket B53 rotates fast through a series of driving shafts G65, and the shaft G65 drives the fan 67 to rotate fast, so that the dust discharging speed of the fan 67 is increased.

As shown in fig. 2, 23 and 24, the brush tips of the two dust removing brushes 40 are inclined towards the roller C43 wrapped around the window screening 31, so that the window screening 31 can be removed before the skylight is opened, and dust attached to the window screening 31 can not enter the room with air in the opening process of the sash 11. During the closing process of the skylight, the dust removing brush 40 can not remove dust on the window screen 31 passing through the dust removing brush 40, so that dust on the window screen 31 brushed by the dust removing brush 40 can be prevented from flying and entering the room through the window screen 31 and the closed skylight.

The side barrier films 30 in the invention are transparent elastic films, so that when the casement 11 is completely opened, the two side barrier films 30 can be in a tight state, and form a mosquito-proof closed space with the tight window screen 31.

The roller A10 of the invention ensures that when the casement 11 is fully opened, the roller A10 and the casement 11 tighten the part of the window screen 31 between the casement 11 and the window frame 6 and form a mosquito-proof closed space with the two side barrier films 30 in a tightened state at both sides.

The one-way ring 58 of the present invention is conventional.

The limit of the limit round block 13 and the arc block 18 relative to each other by the matching of the limit block 15 and the corresponding limit groove 19 can be relieved under the driving of pulling the chain A22 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 6, and the opening sash 11 is in sealing engagement with the seal ring 9 mounted on the window frame 6. One end of each of the two limit blocks 15 is inserted into a corresponding limit groove 19 on the inner wall of the corresponding arc block 18 and forms incomplete limit to the relative position of the sash 11 and the window frame 6. The two pneumatic rods 28 are retracted to a minimum. The two swing rods A24 swing out to the two sides of the window frame 6 around the corresponding shafts C25 respectively and support the side barrier films 30 on the same side outwards, so that the two side barrier films 30 are recycled. The window screen 31 is wound around the roller C43 through the space between the roller a10, the roller B39, and the two dust removing brushes 40. Scroll spring A26, scroll spring B45 and scroll spring C52 are all in a pre-compressed energy storage state. The window screen 31 is in a taut state. The two swing rods B49 are respectively in contact fit with the two swing limit blocks 51. The limit spring 17 is in a compressed energy storage state.

When the skylight needs to be opened, the chain B54 hung in a room is pulled to and fro by hand, and the chain B54 drives the chain wheel B53 to rotate back and forth.

When the chain wheel B53 rotates in the forward direction, the chain wheel B53 drives the two belt wheels A55 and the two swing rods B49 to rotate synchronously through the shaft E48. The two swing rods B49 simultaneously drive the roller D50 to swing upwards around the shaft E48, and the two scroll springs C52 are further compressed and stored with energy simultaneously. Roller D50 pulls window screen 31 under tension from roller C43, window screen 31 pulled from roller C43 is held and pulled by roller D50 and enters the space between arc plate 69 and the inner top of housing 33, roller B39 rotates under the drive of window screen 31, roller C43 rotates under the drive of window screen 31, and two volute spiral springs B45 are further compressed and stored with energy. The window screening 31 drawn out from the roll C43 is moved relative to the two dust removing brushes 40, and since the brush tips of the two dust removing brushes 40 are inclined in the direction of the roll C43 around the window screening 31, the dust on the window screening 31 is cleaned by the brush bristles on the two dust removing brushes 40.

The arc plate 69 supports the window screen 31 drawn by the roller D50 so that the roller D50 draws the window screen 31 longest at the same swing arc, and further so that the portion of the window screen 31 where dust is removed by the dust removing brush 40 is longer, and the dust removed by the dust removing brush flies into the housing 33.

At the same time, the two pulleys a55 each rotate the corresponding pulley B57 via the corresponding timing belt a 56. Since the one-way ring 58 performs a one-way driving function at this time, the two pulleys B57 drive the flywheel 61 and the pulley C62 on the same side to rotate synchronously through the corresponding one-way ring 58 and the corresponding shaft F59, respectively. The two belt wheels C62 drive the corresponding belt wheel D64 to rotate through the synchronous belt B63 on the same side, and the belt wheel D64 drives the fan 67 on the same side to rotate rapidly through the corresponding shaft G65. The two fans 67 discharge the dust flying in the casing 33 through the two dust discharge ports 37 at the same time, thereby preventing the dust from accumulating in the casing 33.

When the chain wheel B53 rotates reversely, the chain wheel B53 drives the two belt wheels A55 and the two swing rods B49 to synchronously rotate reversely through the shaft E48. The two swing rods B49 simultaneously drive the roller D50 to swing downwards around the shaft E48, and the two scroll springs C52 can quickly release energy along with the downward swing of the two swing rods B49 of the roller. With the swinging back of the roller D50 around the shaft E48, the roller C43 mounted on the shaft D44 rotates reversely by the restoring action of the two spiral springs B45 and winds and recovers the window screen 31 which was pulled out of the roller C43 and is in a tightened state, and the roller B39 rotates reversely by the window screen 31. The window screen 31, which was previously pulled out from the roll C43, is caused to move relative to the two dust removing brushes 40. Since the brush tips of the two dust removing brushes 40 are inclined toward the roll C43 around the window screening 31, the brush tips of the two dust removing brushes 40 do not clean the window screening 31 or the cleaning effect is weak.

At the same time, the two pulleys a55 each rotate the corresponding pulley B57 via the corresponding timing belt a 56. Since the one-way ring 58 plays an overrunning role at this time, the two pulleys B57 do not drive the flywheel 61 and the pulley C62 on the same side to continue to accelerate through the corresponding one-way ring 58 and the corresponding shaft F59. Because the inertia of the flywheel 61 is large, the flywheel 61 continues to rotate rapidly, the two flywheels 61 respectively drive the belt wheel C62 on the same side to continue to rotate through the corresponding F, the two belt wheels C62 respectively drive the corresponding belt wheel D64 to continue to rotate rapidly through the synchronous belt B63 on the same side, and the belt wheel D64 drives the fan 67 on the same side to continue to rotate rapidly through the corresponding shaft G65. The two fans 67 continue to simultaneously discharge the dust still flying inside the casing 33 through the two dust discharge ports 37, thereby preventing dust from accumulating inside the casing 33.

After the chain B54 is pulled back and forth several times, when the dust on the window screen 31 is removed, the pulling of the chain B54 is stopped. Roller D50 swings back around shaft E48 to the initial position by the action of two wrap springs C52, and roller C43 rewinds the portion of window screen 31 pulled out by roller D50 completely by the return action of two wrap springs B45. After the pulling of the chain B54 is stopped, the two flywheels 61 are gradually decelerated and finally stopped, and the two fans 67 are stopped as the flywheels 61 are stopped.

Then, a chain A22 hung in a room is pulled by hand, the chain A22 drives a chain wheel A21 to rotate, the chain wheel A21 drives a limit round block 13 to rotate synchronously through a shaft B20, the limit round block 13 drives an opening fan 11 to swing upwards around the central axis of a12 through a corresponding shaft A12, and the opening fan 11 drives another limit round block 13 to rotate synchronously through another shaft A12. The fan 11 drives the two pneumatic rods 28 to extend through the two fixed blocks 29 and swing upward around the hinge points with the corresponding U-shaped seats 27. The two limiting round blocks 13 respectively rotate relative to the corresponding arc blocks 18 at the same time, one limiting-releasing inclined plane 16 on the limiting blocks 15 interacts with the notch edges of the corresponding limiting grooves 19, the two limiting blocks 15 respectively retract and slide towards the corresponding sliding grooves 14 at the same time, the two limiting springs 17 are further compressed to store energy at the same time, and the limiting blocks 15 release the limitation of the relative positions of the casement 11 and the window frame 6.

The window screen 31 and the two side barrier films 30 are pulled upwards by the opening sash 11 which is opened around the central axis of the shaft A12, the two tightened side barrier films 30 respectively and simultaneously drive the two swing rods A24 to respectively retract into the window frame 6 around the corresponding shafts C25, the tightened window screen 31 drives the roller A10 and the roller B39 to rotate, and the window screen 31 pulls the roller C43 to rotate positively. Because the dust on the window screen 31 is removed, in the opening process of the casement 11, the two dust removing brushes 40 still brush the window screen 31 but no dust falls off from the window screen 31, so that the dust on the window screen enters the room to pollute the air in the room in the opening process of the skylight.

When the fan 11 is completely opened to the horizontal position, the two limit blocks 15 just face to another limit groove 19 on the inner wall of the corresponding arc block 18 and enter the corresponding limit groove 19 under the action of the corresponding limit spring 17, so that incomplete limit is formed on the fan 11 in the horizontal state. The two pneumatic rods 28 are extended to the longest and form an auxiliary support for the opened fan 11. At this time, the two side blocking films 30 are vertically tightened, the two side blocking films 30 and the pulled window screen 31 form a closed space for preventing mosquitoes from entering, the two swing rods a24 are completely recovered to the two swing grooves 7 on the window frame 6 by the two side blocking films 30, and the two spiral springs a26 are further compressed to store energy.

When the skylight needs to be closed, the chain A22 is pulled forcefully and reversely, the chain A22 drives the chain wheel A21 to rotate reversely, the chain wheel A21 drives the limiting round block 13 to rotate synchronously and reversely through the shaft B20, and the limiting round block 13 drives the fan 11, the other shaft A12 and the other limiting round block 13 to rotate and swing synchronously through the corresponding shaft A12. The other limit-releasing inclined plane 16 on the two limit blocks 15 interacts with the notch edge of the limit groove 19, the two limit blocks 15 simultaneously contract inwards the corresponding sliding grooves 14 and release the limit of the downward swing of the opening fan 11 around the shaft A12, and the two limit springs 17 are further compressed to store energy. The two pneumatic rods 28 are compressed by the opening fan 11 while swinging down around the hinge point with the corresponding U-shaped seat 27. Meanwhile, the two side barrier films 30 and the window screen 31 are loosened, the two swing rods a24 swing out of the swing grooves 7 and swing towards the two sides of the window frame 6 under the reset action of the corresponding volute spiral springs a26, and the two swing rods a24 support the two loosened side barrier films 30 outwards to complete the recovery of the side barrier films 30. The roller C43 mounted on the shaft D44 is reversely rotated by the returning action of the two wrap springs B45 and winds and recovers the loosened window screen 31.

When the casement 11 is completely closed, the two limit blocks 15 are respectively just opposite to the limit grooves 19 at the initial positions on the corresponding arc blocks 18, and under the reset action of the corresponding limit springs 17, the two limit blocks 15 simultaneously and quickly enter the limit grooves 19 to form incomplete limit on the closed state of the casement 11, so that the windowing in the sealed closed state is prevented from being loosened under the treading of wind power or flying birds, and the skylight 2 is ensured to be always closed by the casement 11.

After a period of use, some dust accumulates in the housing 33. Water is sprayed into the housing 33 through the water inlet 35, and the water sprayed into the housing 33 washes a small amount of dust accumulated in the housing 33 and is discharged through the water outlet groove 36.

In conclusion, the beneficial effects of the invention are as follows: before the window sash 11 is opened, the chain B54 is repeatedly pulled to carry the chain wheel B53 to rotate in a reciprocating mode, the chain wheel B53 drives the roller D50 to pull the window screen 31 wound on the roller C43 to move through a series of transmissions, and dust on the moving window screen 31 is brushed off under the action of the two dust removal brushes 40, so that the dust attached to the window screen 31 cannot enter a room through the window screen 31 in the opening process of the skylight. Meanwhile, the dust on the window screen 31 is prevented from flying in the brushing process by the two dust removing brushes 40 and entering the room through the window screen 31, so that the indoor air is prevented from being polluted.

During the closing of the skylight 2 by the opening of the window, the roller C43 winds and recovers the window screen 31. In the process of opening the skylight opening 2, the window opening pulls out the window screen 31 wound on the roller C43 and forms an anti-mosquito closed space with the two side barrier films 30.

In addition, in the process of removing dust from the window screening 31 by the two dust removing brushes 40, the chain B54 drives the two fans 67 through a series of transmission to discharge dust brushed off from the window screening 31 outwards in time, so as to prevent secondary pollution caused by dust accumulated in the housing 33 to the window screening 31 brushed off.
