In order to ensure that the circuit is not short-circuited by rain and snow, the waterproof shell can be hooped outside the first motor and the second motor. This is prior art and will not be described in detail and will not be shown in the figures.

The through groove 951 of the connecting rod 95 is aligned with the protrusion 94 by descending the electric push rod II 92, so that the connecting rod 95 is separated from the protrusion 94 and overturned forward by 90 degrees, the transverse plate 10 is close to the skylight, the sliding rod 102, the spring II 104 and the contact piece 103 are matched to achieve the detection effect, when the snow received at the top end of the sliding rod 102 descends to a certain degree to be in contact with the contact piece 103, the motor II 105 starts to work, and the shovel piece 101 moves back and forth to clean the snow on the skylight 3. The phenomenon that when the skylight 3 is opened, too much snow is accumulated to press the glass out of cracks is avoided, and the effect of protecting the skylight 3 glass is achieved.

A use method of a window capable of automatically opening the window and ventilating without people in winter is disclosed:

s1, when people go out to work in the daytime, the sunlight irradiates on the photovoltaic panel 4, and the photovoltaic panel 4 is illuminated to gradually generate electric energy.

S2, the storage battery 7 slowly stores the electric energy generated by the photovoltaic panel 4, and meanwhile, the storage battery 7 supplies power to the plurality of electromagnets

36, the electromagnets 36 generate magnetic force at the same time, and the electromagnets 36 repel each other, so that the electromagnets 36 have force for pushing the sliding sheet 35 to move.

S3, the electric energy is small and the current is weak, so that the magnetic force generated between the electromagnets 36 is weak, the repulsive force between the electromagnets 36 is small, and the distance between the sliding pieces 35 is not large.

S4, increasing the accumulated electric energy of the storage battery 7 along with the time, increasing the current provided for the electromagnet 36, and increasing the magnetic pole generated by the electromagnet 36, when the magnetic pole is increased to a certain extent, the electromagnet 36 pushes the sliding sheet 35 to make the sliding sheets 35 far away from each other, and the sliding sheet 35 is in contact with the first spring 34 coil, so that the first spring 34 is driven to unfold.

And S5, according to S4, the first spring 34 is unfolded, the electromagnet 36 pushes the magnetic block 33 to move, the magnetic block 33 drives the iron blocks 52 to move, the two iron blocks 52 are separated from each other, the single chip microcomputer 6 controls the motor 13 to rotate, and the motor 13 drives the skylight 3 to be turned upwards.

S6, passing S4 and S5, the skylight 3 is turned up and the iron blocks 52 are far away from each other, the lower end of the first steel wire 53 pulls the moving piece 54, the first steel wire 53 is tensioned due to the upturning of the skylight 3, the side windows 2 are pulled outwards, the two side windows 2 are enabled to rotate outwards and are far away, then the first steel wire 53 moves to the farthest position along with the iron blocks 52, the first steel wire 53 pulls the side windows 2 to rotate outwards continuously through the moving piece 54, and finally the side windows 2 are opened completely.

In summary, in the window capable of automatically opening the window and ventilating when no person is in winter, the same magnetic poles repel each other and are far away from each other by virtue of magnetic force, so that the magnetic field generated after the electromagnet 36 is electrified generates repulsive force because the magnetic blocks 33 and the magnetic poles at the opposite ends of the electromagnets 36 are the same. The magnet 33 is enabled to move, the magnet 33 drives the iron block 52, the iron block 52 pulls the moving sheet 54 through the first steel wire 53, the side window 2 is enabled to be opened along with the skylight 3, and therefore the effect of automatic window opening and ventilation under the unmanned condition is achieved. Avoiding the indoor air from being not circulated. Then, the curtain 82, the balancing weight 83 and the first electric push rod 84 are matched with each other, so that when the window is opened and snows suddenly in the weather, the curtain 82 descends to block the window, and the indoor ground is prevented from being wet due to the fact that rain and snow enter the room.

And the through groove 951 of the connecting rod 95 is aligned with the protrusion 94 by descending the electric push rod II 92, so that the connecting rod 95 is separated from the protrusion 94 and overturned forward by 90 degrees, the transverse plate 10 is close to the skylight, the sliding rod 102, the spring II 104 and the contact piece 103 are matched to achieve the detection effect, when the snow received at the top end of the sliding rod 102 descends to a certain degree to be in contact with the contact piece 103, the motor II 105 starts to work, and the shovel piece 101 moves back and forth to clean the accumulated snow on the skylight 3. The phenomenon that when the skylight 3 is opened, too much snow is accumulated to press the glass out of cracks is avoided, and the effect of protecting the skylight 3 glass is achieved.
