[0035] Each shutter blade 3 has a folded corner extending on the front and rear sides to strengthen the closed range.

[0036] The contact surfaces of the friction wheel 4001 and the friction strip 8 are both provided with a rubber layer to enhance the friction force.

[0037] The cross section of the friction strip 8 in the vertical direction is trapezoidal, and after the friction strip 8 and the friction wheel 4001 are worn, the trapezoidal inclined surface still keeps the two in contact.

[0038] When using the blinds, in a strong light environment, when the blades are in a fully closed state, when the user needs to temporarily observe the outside world, the blades in the existing blinds cannot be flipped individually, and the sudden strong light from flipping all the blades is dazzling, resulting in obstructed vision and damage to eyesight;

[0039] The present invention provides a sealed dustproof intelligent blind window to address the above problems;

[0040] The window frame 1 is installed in the same manner as the existing windows. Before using the present invention, the lithium battery in the window frame 1 is fully charged. An electric component control button is provided on the left side of the window frame 1. At this time, all the louvers 3 are in a retracted state above the window frame 1. The user presses the control button to start the dual-axis motor 101. The dual-axis motor 101 drives the winding roller 102 to rotate clockwise as viewed from right to left, so that the pull rope 103 on the winding roller 102 is released and moves downward under the action of the bottom plate 104's own gravity until the pull rope 103 is completely released and the bottom plate 104 moves down to the limit position. All movable blocks 2 lose the obstruction of the bottom plate 104 and also move downward under their own gravity. The limit rope 2001 makes the movable blocks 2 equidistantly arranged from top to bottom, and all the louvers 3 are unfolded. Figure 1 State; it should be noted that at this time, all friction wheels 4001 are not in contact with friction strip 8, and the user pushes the lever 1b to the left, and the lever 1b drives the friction strip 8 to move to the left, so that all friction wheels 4001 and friction strip 8 are located at the far left, and all friction wheels 4001 are in contact with friction strip 8, and then the user operates the control button to make the electric gear shaft 7 work, and the electric gear shaft 7 rotates counterclockwise as viewed from right to left. Since the electric gear shaft 7 is meshed with the rack of the friction strip 8, the friction strip 8 moves up, and the friction strip 8 rubs against the friction wheel 4001 during the upward movement, driving the friction wheel 4001 to rotate clockwise as viewed from right to left, and the friction wheel 4001 drives the shaft sleeve 4 to rotate, and the shaft sleeve 4 then drives the spline shaft 3002 to rotate, so that the rotating rod 3001 rotates to control the flipping angle of the louver blades 3. This process realizes the control of the simultaneous flipping of all louver blades 3;

[0041] When the user needs to flip a certain louver blade 3 separately, Figure 3Here, taking the flipping of the bottom shutter blade 3 as an example, the user pushes the lever 1b to the right, and the lever 1b drives the friction strip 8 to move to the right. At this time, the friction strip 8 is separated from all friction wheels 4001. Then the user removes the magnetic block 1a from the slide groove 1002 and moves it to the shutter blade 3 that needs to be controlled. At this time, the magnetic block 1a is attracted by the wedge block Ⅰ5, so that the corresponding wedge block Ⅰ5 moves forward from the initial rear position along the longitudinal limit strip 2003, and the inclined surface of the wedge block Ⅰ5 cooperates with the inclined surface of the wedge block Ⅱ6, and pushes the wedge block Ⅱ6 from the initial left position along the transverse limit strip 2004. The wedge block II 6 moves to the right, and the wedge block II 6 moves to drive the corresponding shaft sleeve 4 and the friction wheel 4001 to move to the right, so that the corresponding friction wheel 4001 contacts the friction strip 8 again. Then the user controls the electric gear shaft 7 to work again, and the electric gear shaft 7 drives the friction strip 8, so that the friction strip 8 contacts the friction wheel 4001 with friction, and drives the friction wheel 4001 and related parts to rotate, so as to realize the flipping control of the single louver blade 3, so as to avoid that the blades in the existing louver window cannot be flipped individually under strong light, and the strong light caused by flipping all the blades is dazzling, resulting in obstruction of vision and damage to vision;

[0042] When some blades of the existing closed structure cannot be turned over normally, it is difficult to disassemble and the maintenance is cumbersome, and the cost of replacing the entire window is high and the economic efficiency is poor. Figure 3 For example, the upper louver blade 3 cannot be turned over normally. After using the turning function, the friction wheel 4001 on the lower side is located at the rightmost side. First, the friction strip 8 is in friction contact with the friction wheel 4001 to control the lower louver blade 3 to turn over to the same vertical state as the upper side. Then, the lever 1b is moved to the left, so that the friction strip 8 pushes the friction wheel 4001 in contact with it to reset to the left through the trapezoidal slope, so that all friction wheels 4001 are on the same vertical line at the initial position. Then, the friction strip 8 is controlled to move up and down by controlling the electric gear shaft 7 to contact the two friction wheels 4001 to drive the two friction wheels 4001 to simultaneously drive the corresponding louver blades 3 to turn over. Adjustment through the above operations can restore all louver blades 3 to the same posture, and the turning function is used normally to avoid the difficulty of disassembly of the closed structure and cumbersome maintenance when some blades cannot turn over normally.

[0043] At the same time, when the user uses the independent flipping function and does not know whether the shutter blade 3 is in the independent flipping position, the independent flipping function can be used again after the above operation.

[0044] Embodiment 2, on the basis of embodiment 1, as Figure 1 , Figure 4-Figure 5 and Figure 7-Figure 8As shown, a manual control system is also included, which includes a thumbwheel Ⅰ201, a driven wheel Ⅰ202, a thumbwheel Ⅱ203 and a driven wheel Ⅱ204; an installation cavity is provided on the upper side of the window frame 1; a thumbwheel Ⅰ201 is rotatably connected in the installation cavity; a part of the thumbwheel Ⅰ201 extends out of the window frame 1; a driven wheel Ⅰ202 is fixedly connected to the output shaft of the double-axis motor 101; the driven wheel Ⅰ202 and the thumbwheel Ⅰ201 are driven by a belt; another installation cavity is provided at the lower part of the window frame 1; a thumbwheel Ⅱ203 is rotatably connected in the installation cavity; a part of the thumbwheel Ⅱ203 extends out of the window frame 1; a driven wheel Ⅱ204 is fixedly connected to the right side of the electric gear shaft 7; the driven wheel Ⅱ204 and the thumbwheel Ⅱ203 are driven by a belt; rubber rings for sealing are provided on the output shaft of the double-axis motor 101 and the electric gear shaft 7.

[0045] It also includes a connecting pipe 205; a connecting groove 1005 is opened at the lower part of the window frame 1; the connecting pipe 205 is installed on the lower side of the window frame 1; the connecting pipe 205 is connected to the connecting groove 1005; a one-way valve is arranged in the connecting pipe 205; and a plug 20501 is arranged at the outlet of the connecting pipe 205.

[0046] A rubber gasket is provided on the contact surface between the glass 1001 and the window frame 1 .

[0047] When the battery power is insufficient, the electric component cannot work, and the user cannot retract and flip the louver 3, or in strong weather, the electric component overheats and triggers protection to stop working. At this time, the louver 3 is in an open state, and the user cannot control the louver 3 to close and block the sunlight; in this regard, when the user needs to retract and extend the shutter, by manually rotating the dial wheel Ⅰ201, the dial wheel Ⅰ201 drives the output shaft of the dual-axis motor 101 to rotate through the belt-driven driven wheel Ⅰ202, and then drives the winding roller 102 to rotate to retract the pull rope 103, so that the pull rope 103 drives the bottom plate 104 to move up and down, and the bottom plate 104 drives all the louver blades 3 to move, so as to realize the retraction and extension of all the louver blades 3, and avoid the louver blades 3 being unable to be retracted and extended when the electric component cannot work;

[0048] When the user needs to perform a flipping operation, the user manually rotates the thumbwheel II203, and the thumbwheel II203 drives the electric gear shaft 7 to rotate through the belt drive driven wheel II204. The electric gear shaft 7 is meshed with the rack of the friction strip 8 to drive the friction strip 8 to move up and down. The friction strip 8 and the friction wheel 4001 rub to rotate, thereby driving the relevant parts to rotate, and realizing the flipping of the shutter blade 3, so as to avoid the shutter blade 3 being unable to perform the flipping operation when the electric parts cannot work;

[0049] During long-term use, after the glass 1001 is damaged and replaced, air enters the window frame 1, the vacuum state is lost, and the heat insulation effect is reduced; therefore, after the user replaces the glass 1001, the user opens the plug 20501, connects the exhaust device at the connecting pipe 205, and exhausts the air in the window frame 1 through the connecting groove 1005 to restore the vacuum state in the window frame 1. The one-way valve in the connecting pipe 205 prevents air from entering the window frame 1 through the connecting pipe 205. After evacuation, the plug 20501 is closed again to complete the vacuum operation; to avoid the window frame 1 losing the vacuum state and reducing the heat insulation effect after the glass 1001 is replaced; in addition, when the sealant of the glass 1001 loses its sealing effect during long-term use, the user can restore the vacuum state in the window frame 1 through the above operation after re-sealing;

[0050] It should be noted that after the window frame 1 is evacuated, negative pressure is formed, so that the two pieces of glass 1001 are adsorbed toward the middle, and at the same time, the rubber ring provided on the inner side thereof is pressed tightly, thereby increasing the sealing performance of the present invention.

[0051] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application.
