Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The purpose of the present invention is to provide a ventilation window with a light adjustment function, which can achieve adjustable light in a non-ventilated state and can meet the diverse lighting needs of users.

[0029] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] As Figures 1 - 8 shown, this embodiment provides a ventilation window 100 with a light adjustment function, including a window frame 1, a driving mechanism, and a plurality of window leaves. The window leaves include a rectangular frame 2, an outer glass 9, an inner glass 10, and a linear telescopic driving component 11. An upper sealing strip 3 and a lower sealing strip 4 are respectively arranged on the upper and lower parts of the rectangular frame 2. A first rotating shaft 5 and a second rotating shaft 6 are respectively arranged at both ends of the rectangular frame 2. The first rotating shaft 5 and the second rotating shaft 6 are respectively rotatably installed on both sides inside the window frame 1. The angles between the plurality of window leaves and the horizontal plane are the same. The driving mechanism is used to drive the plurality of first rotating shafts 5 to rotate synchronously. When the plurality of rectangular frames 2 are vertically arranged, the upper sealing strip 3 on the uppermost rectangular frame 2 fits against the inner wall of the window frame 1 to achieve sealing. The lower sealing strip 4 on the upper rectangular frame 2 in two adjacent rectangular frames 2 fits against the upper sealing strip 3 on the lower rectangular frame 2 to achieve sealing. The lower sealing strip 4 on the lowermost rectangular frame 2 fits against the inner wall of the window frame 1 to achieve sealing.

[0031] The outer glass 9 is fixed in the rectangular frame 2. An annular groove is provided inside the rectangular frame 2, and the annular groove is located inside the outer glass 9. The inner glass 10 is slidably installed in the annular groove. The linear telescopic driving member 11 is arranged at the upper or lower part of one end of the rectangular frame 2, and the linear telescopic driving member 11 is used to drive the inner glass 10 to move along the length direction of the rectangular frame 2. A plurality of first polarizing films 14 and a plurality of second polarizing films 15 are sequentially arranged at intervals along the length direction of the outer glass 9. A plurality of first polarizing films 14 and a plurality of second polarizing films 15 are sequentially arranged at intervals along the length direction of the inner glass 10. The total number of the first polarizing films 14 and the second polarizing films 15 on the inner glass 10 is greater than the total number of the first polarizing films 14 and the second polarizing films 15 on the outer glass 9. The polarization directions of the first polarizing film 14 and the second polarizing film 15 are perpendicular to each other, that is, when the first polarizing film 14 overlaps with the second polarizing film 15, the overlapping area is in a light-tight state.

[0032] When the light needs to be adjusted, the linear telescopic driving member 11 drives the inner glass 10 to move along the length direction of the rectangular frame 2, so that the overlapping area of the first polarizing film 14 and the second polarizing film 15 on the inner glass 10 and the first polarizing film 14 and the second polarizing film 15 on the outer glass 9 changes. The light can be adjusted in a non-ventilated state, which can meet the diverse lighting needs of users.

[0033] Specifically, when the first polarizing film 14 on the inner glass 10 overlaps with the second polarizing film 15 on the outer glass 9, the overlapping area is in a light-tight state; when the second polarizing film 15 on the inner glass 10 overlaps with the first polarizing film 14 on the outer glass 9, the overlapping area is in a light-tight state; when the first polarizing film 14 on the inner glass 10 overlaps with the first polarizing film 14 on the outer glass 9, the overlapping area is in a light-transmitting state; when the second polarizing film 15 on the inner glass 10 overlaps with the second polarizing film 15 on the outer glass 9, the overlapping area is in a light-transmitting state. By moving the inner glass 10, the light can be adjusted, so that each window leaf has different light-transmitting states. When the window leaf is inclined, it is in a ventilated and light-transmitting state. At this time, the light-transmitting state can also be further adjusted by moving the inner glass 10.

[0034] Specifically, a hollow chamber is provided inside one side of the window frame 1, and each first rotating shaft 5 passes through the hollow chamber and is rotatably installed on the window frame 1. A plurality of mounting holes are sequentially arranged from top to bottom on the other side of the window frame 1, and each second rotating shaft 6 is rotatably installed in one mounting hole, thereby realizing the rotational installation of the window leaf.

[0035] The driving mechanism includes a power component 8 and a synchronous transmission component. The synchronous transmission component is arranged in the hollow chamber and is connected to a plurality of first rotating shafts 5. The power component 8 is arranged at the lower part of the window frame 1 and is used to drive a plurality of first rotating shafts 5 to rotate synchronously through the synchronous transmission component.

[0036] Specifically, a receiving groove communicating with the bottom of the hollow chamber is provided in the lower part of the window frame 1, and the power component 8 is arranged in the receiving groove.

[0037] As Figure 2 shown, the power component 8 in this embodiment is a rotary motor. The synchronous transmission assembly includes a driving sprocket, a chain 7 and a plurality of driven sprockets. A driven sprocket is fixedly sleeved on each first rotating shaft 5, and a driving sprocket is fixedly sleeved on the power output shaft of the rotary motor. The chain 7 is wound around the driving sprocket and the plurality of driven sprockets.

[0038] When the angle of the window leaf needs to be adjusted, the rotary motor drives the driving sprocket to rotate, and then drives the plurality of driven sprockets to rotate through the chain 7, so that the plurality of first rotating shafts 5 rotate synchronously, thereby changing the angles of the plurality of window leaves.

[0039] On one side of the outer glass 9 close to the inner glass 10, a plurality of first polarizing films 14 and a plurality of second polarizing films 15 are sequentially arranged at intervals along its length direction. On one side of the inner glass 10 close to the outer glass 9, a plurality of first polarizing films 14 and a plurality of second polarizing films 15 are sequentially arranged at intervals along its length direction.

[0040] As Figure 5 and Figure 6 shown, the length and height of the inner glass 10 are respectively greater than the length and height of the outer glass 9. The lengths of the first polarizing film 14 on the outer glass 9, the second polarizing film 15 on the outer glass 9, the first polarizing film 14 on the inner glass 10 and the second polarizing film 15 on the inner glass 10 are all the same.

[0041] In this specific embodiment, the difference between the total number of the first polarizing film 14 and the second polarizing film 15 on the inner glass 10 and the total number of the first polarizing film 14 and the second polarizing film 15 on the outer glass 9 is one.

[0042] When the first polarizing film 14 and the second polarizing film 15 on the inner glass 10 completely overlap with the first polarizing film 14 and the second polarizing film 15 on the outer glass 9 respectively, it is in a completely light-transmitting state; when the first polarizing film 14 and the second polarizing film 15 on the inner glass 10 completely overlap with the second polarizing film 15 and the first polarizing film 14 on the outer glass 9 respectively, it is in a light-blocking state. By moving the inner glass 10, the light can be switched between the completely light-transmitting state and the light-blocking state. In addition to the above two states, there are also various light-transmitting states with different light transmittances.

[0043] Specifically, the number of the first polarizing film 14 on the inner glass 10 is the same as the number of the first polarizing film 14 on the outer glass 9, and the difference between the number of the second polarizing film 15 on the inner glass 10 and the number of the second polarizing film 15 on the outer glass 9 is one.

[0044] The annular groove in this embodiment includes an upper horizontal groove, a right vertical groove 13, a lower horizontal groove, and a left vertical groove 12 that are connected end to end in sequence. The upper horizontal groove extends along the inner wall of the upper part of the rectangular frame 2, the right vertical groove 13 extends along the inner wall of the right side of the rectangular frame 2, the lower horizontal groove extends along the inner wall of the lower part of the rectangular frame 2, and the left vertical groove 12 extends along the inner wall of the left side of the rectangular frame 2. The upper and lower ends of the inner glass 10 are slidably installed in the upper horizontal groove and the lower horizontal groove respectively. The left vertical groove 12 and the right vertical groove 13 provide accommodation spaces for the left and right sides of the inner glass 10, enabling it to move along the length direction of the rectangular frame 2.

[0045] As Figure 4 shown, in this embodiment, the linear telescopic driving member 11 is arranged at the lower part of one end of the rectangular frame 2, and the telescopic rod of the linear telescopic driving member 11 can extend into the left vertical groove 12 to be connected to one end of the inner glass 10.

[0046] In this specific embodiment, the linear telescopic driving member 11 is a linear motor.

[0047] In this specific embodiment, the lengths of the upper sealing strip 3 and the lower sealing strip 4 are both the same as the length of the rectangular frame 2, thereby ensuring the sealing effect.

[0048] Specifically, the upper sealing strip 3 and the lower sealing strip 4 have the same shape and the cross-section of both is a right triangle. The two mutually perpendicular side surfaces of the upper sealing strip 3 are respectively fixed to the upper part of the rectangular frame 2 and flush with the inner side of the rectangular frame 2, and the two side surfaces of the lower sealing strip 4 are respectively fixed to the lower part of the rectangular frame 2 and flush with the outer side of the rectangular frame 2.

[0049] When multiple rectangular frames 2 are arranged vertically, the top of the upper sealing strip 3 on the uppermost rectangular frame 2 fits against the inner wall of the window frame 1 to achieve sealing. The inclined surface of the lower sealing strip 4 on the upper rectangular frame 2 among two adjacent rectangular frames 2 can fit against the inclined surface of the upper sealing strip 3 on the lower rectangular frame 2, and the bottom of the lower sealing strip 4 on the lowermost rectangular frame 2 fits against the inner wall of the window frame 1 to achieve sealing.

[0050] This embodiment also includes a controller. The driving mechanism and the linear telescopic driving member 11 are both connected to the controller. Specifically, the power component 8 is connected to the controller, that is, the rotary motor and the linear motor are both connected to the controller, and the controller controls the operation of the rotary motor and the linear motor.

[0051] The specific usage process is: As Figure 7As shown, when ventilation is required, the rotating motor drives the driving sprocket to rotate, and through the chain 7, the driven sprocket and the first rotating shaft 5, the window leaves are driven to rotate, so that the window leaves are inclined outward from top to bottom. At this time, it is also in a light-transmitting state. When further adjustment of the light-transmitting state is required, the linear motor can be used to drive the inner glass 10 to move along the length direction of the rectangular frame 2, thereby adjusting the light-transmitting state of each window leaf.

[0052] As Figure 8 shown, when airtightness is required, the rotating motor drives the driving sprocket to rotate, and through the chain 7, the driven sprocket and the first rotating shaft 5, the window leaves are driven to rotate, so that the window leaves are set vertically. When adjustment of the light-transmitting state is required, the linear motor can be used to drive the inner glass 10 to move along the length direction of the rectangular frame 2, thereby adjusting the light-transmitting state of each window leaf.

[0053] In this specification, specific examples are used to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
