[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0036] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0037] like Figure 1 As shown, the present invention provides a folding screen window for outward-opening windows, comprising: a plurality of folding units 1 connected in sequence, wherein the two folding units 1 located on the outer sides are respectively used to connect with a fixed window frame 4 and an outward-opening window frame 5;

[0038] When the outward-opening window frame 5 is opened, the multiple folding units 1 are fan-shaped to block the gap formed by the fixed window frame 4 and the outward-opening window frame 5; when the outward-opening window frame 5 is closed, the multiple folding units 1 are stored between the fixed window frame 4 and the outward-opening window frame 5.

[0039] The fixed window frame 4 and the outward-opening window frame 5 are sealed and rotatably connected, and a plurality of folding units 1 connected in sequence can be unfolded to a certain angle, for example, within the angle range of 0 degrees to 90 degrees, and can be unfolded to any angle;

[0040] When the outward-opening window frame 5 is opened, the multiple folding units 1 are expanded to a certain angle according to the opening angle of the outward-opening window frame 5, and the multiple folding units 1 are changed from a contracted state to an expanded state, thereby blocking the gap formed by the fixed window frame 4 and the outward-opening window frame 5, thereby separating the indoor and outdoor areas; when the outward-opening window frame 5 is closed, the multiple folding units 1 are contracted and folded together as the outward-opening window frame 5 is closed, and are stored between the outward-opening window frame 5 and the fixed window frame 4.

[0041] Through the above design, when the outward-opening window frame 5 is opened or closed, the multiple folding units 1 can be expanded and folded as the outward-opening window frame 5 is opened and closed, so that when the outward-opening window frame 5 is operated, mosquitoes can be effectively blocked from entering, and there is no need to manually open or close the multiple folding units 1 individually, which makes the operation simple.

[0042] like Figure 2 As shown, in one embodiment, the folding unit 1 includes two screen window bodies 2 , the outer sides 201 of the two screen window bodies 2 are connected to each other, and the inner sides 202 of the screen window bodies 2 are connected to adjacent folding units 1 .

[0043] The inner side edge 202 of the screen body 2 of one folding unit 1 is connected to the inner side edge 202 of the screen body 2 of the adjacent folding unit 1;

[0044] The screen window body 2 can be made of any material used to make screen windows in the prior art.

[0045] When the multiple folding units 1 are unfolded to the maximum angle, for example, 90 degrees, the two screen bodies 2 of each folding unit 1 still have an included angle smaller than the set angle. The set angle can be set to 90 degrees to 120 degrees to ensure that the multiple folding units 1 can be easily folded and unfolded next time.

[0046] The connection between the outer edges 201 or inner edges 202 of adjacent screen window bodies 2 can be one-piece molded, and the connection points are all memory creases, that is, they can be folded and contracted according to the creases at the connection points after each unfolding; or, the outer edges 201 or inner edges 202 of adjacent screen window bodies 2 are connected by gluing, magnetism or sewing.

[0047] like Figure 3 As shown, in one embodiment, the screen body 2 includes: a first window piece 21, a second window piece 22 and a third window piece 23 connected in sequence, the first window piece 21 and the third window piece 23 are arranged up and down, and the second window piece 22 is connected between the first window piece 21 and the third window piece 23.

[0048] The outer edges of the interconnected first window piece 21 , second window piece 22 and third window piece 23 form the outer edge 201 of the screen window body 2 , and the inner edges of the interconnected first window piece 21 , second window piece 22 and third window piece 23 form the inner edge 202 of the screen window body 2 .

[0049] like Figure 4 As shown, in one embodiment, the two folding units 1 located on the outside are both provided with fixed window pieces 3, which are used to be connected to the fixed window frame 4 or the outward-opening window frame 5; the fixed window pieces 3 are connected to the inner side 202 of the screen body 2.

[0050] The fixed window panel 3 can be made of hard materials, such as plastic or metal, and the fixed window panel 3 is sealed and detachably connected to the fixed window frame 4 and the outward-opening window frame 5; for example, a mounting strip can be set on the surface of the fixed window panel 3, and a first magnetic sheet can be set on the mounting strip, and mounting grooves corresponding to the mounting strip can be set on the fixed window frame 4 and the outward-opening window frame 5, and the mounting strip and the mounting groove are sealed and clamped, or a second magnetic sheet corresponding to the first magnetic sheet can be set in the mounting groove to realize a sealed and detachable connection between the fixed window panel 3 and the fixed window frame 4 and the outward-opening window frame 5.

[0051] like Figure 5As shown, in one embodiment, the fixed window frame 4 and the outward-opening window frame 5 are connected via a rotating shaft, and a plurality of folding units 1 are connected to each other on one side close to the rotating shaft.

[0052] The side of multiple first window panels 21 close to the rotating shaft is sealed with the side of the two fixed window panels 3 close to the rotating shaft, and the side of multiple third window panels 23 close to the rotating shaft is sealed with the side of the two fixed window panels 3 close to the rotating shaft; the fixed window frame 4 and the outward-opening window frame 5 are sealed and rotated, which can effectively achieve shielding and prevent mosquitoes from entering.

[0053] like Figure 6-Figure 8 As shown, in one embodiment, a first receiving groove 51 corresponding to the fixed window piece 3 is provided on the side of the outward-opening window frame 5 close to the fixed window frame 4, and a second receiving groove 41 corresponding to the fixed window piece 3 is provided on the side of the fixed window frame 4 close to the outward-opening window frame 5.

[0054] When the multiple folding units 1 are folded and contracted as the outward-opening window frame 5 is closed, the first storage groove 51 and the second storage groove 41 can store the folded and contracted folding units 1;

[0055] The fixed windows 3 of the folding units 1 on both sides are detachably sealed and connected to the first receiving groove 51 and the second receiving groove 41 respectively.

[0056] like Figure 8 and Figure 9 As shown, in one embodiment, a support member 42 is provided in the second receiving groove 41, and a mounting plate 43 corresponding to the fixed window piece 3 is provided on the side of the support member 42 close to the outward-opening window frame 5, and the mounting plate 43 can be inserted into the first receiving groove 51; when the outward-opening window frame 5 is closed, the outward-opening window frame 5 can be inserted into the second receiving groove 41.

[0057] The multiple folded folding units 1 are stored between the mounting plate 43 and the first storage groove 51 .

[0058] Furthermore, an elastic layer can be provided on the side of the mounting plate 43 in contact with the fixed window panel 3, so that when multiple folding units 1 are accommodated, the multiple folding units 1 can be elastically squeezed between the mounting plate 43 and the first receiving groove 51, thereby ensuring the sealing of the window when it is closed.

[0059] Furthermore, the support member 42 may be an elastic block made of rubber material, and the elastic block is arranged along the length direction of the second receiving groove 41 .

[0060] The support member 42 can be set as an elastic block. In order to further ensure the sealing of the window and prevent hard squeezing of the multiple folding units 1, the support member 42 is set as an elastic block, which can make the storage space of the multiple folding units 1 retractable. In this way, after long-term use, the dust attached to the surface of the multiple folding units 1 will increase the thickness of their contracted folding. The retractable storage space can ensure that the multiple folding units 1 are effectively stored, preventing the closing of the outward-opening window frame 5 from being hindered due to the increase in the thickness of the multiple folding units 1.

[0061] like Figure 9 and Figure 10 As shown, in one embodiment, the fixed window frame 4 and the outward-opening window frame 5 are connected by a rotating shaft, and the multiple folding units 1 are connected to the telescopic fixing part 6 on the side close to the rotating shaft. The telescopic fixing part 6 can expand or contract in a fan shape with the multiple folding units 1.

[0062] The first windows 21 and the two fixed windows 3 are connected by a telescopic fixing portion 6 , and the third windows 23 and the two fixed windows 3 are connected by a telescopic fixing portion 6 .

[0063] The principle of expansion and contraction of the telescopic fixing part 6 is the same as that of the multiple folding units 1. The difference is that the two sides of the telescopic fixing part 6 are closed, so that the whole is a closed fan-shaped body. The telescopic fixing part 6 and the multiple folding units 1 are integrally formed or fixedly connected. The fixed connection method can be gluing or sewing.

[0064] like Figure 11-14 As shown, in one embodiment, a first air cavity 61 and a second air cavity 62 are provided in the telescopic fixing portion 6. When the telescopic fixing portion 6 is unfolded, a first blowing hole 63 communicating with the first air cavity 61 and a second blowing hole 64 corresponding to the second air cavity 62 are provided on the side facing the multiple folding units 1.

[0065] The first air blowing holes 63 are used to provide airflow to the outer surfaces of the folding units 1 , and the second air blowing holes 64 are used to provide airflow to the inner surfaces of the folding units 1 .

[0066] The telescopic fixing portion 6 is entirely sealed.

[0067] Furthermore, an air pipe 7 is provided on a side of the telescopic fixing portion 6 close to the fixed window frame 4 , and the air pipe 7 is connected to an air pump 8 provided on the fixed window frame 4 .

[0068] like Figure 12 and Figure 14As shown, the first air cavity 61 and the second air cavity 62 are respectively provided with an air pipe 7 connected to the air pump 8. The part of the air pipe 7 passing through the fixed window frame 4 is a non-deformable hard pipe, such as a steel pipe, and the part passing through the second receiving groove 41 is a retractable bellows. The bellows and the hard pipe are sealed by threads.

[0069] The airflow provided by the first blowing holes 63 is used to remove debris such as leaves attached to the multiple folding units 1;

[0070] The airflow provided by the second blowing holes 64 is used to remove dust attached to the multiple folding units 1;

[0071] During cleaning, the multiple folding units 1 are preferably kept at the maximum unfolding angle, and air is selectively supplied to the first air cavity 61 and the second air cavity 62 by the air pump 8 to facilitate cleaning; the two air pipes 7 communicating with the first air cavity 61 and the second air cavity 62 can be connected to the air pump 8 via a three-way valve; in addition, a flow regulating valve can be provided on each air pipe 7 to adjust the blowing flow rate;

[0072] During cleaning, the outer and inner surfaces of the multiple folding units 1 can be selectively cleaned sequentially or simultaneously;

[0073] When cleaning the outer surface first and then the inner surface, larger debris such as leaves can be removed first, and then the dust can be cleaned conveniently; when cleaning the inner surface first and then the outer surface, the dust can be cleaned first to prevent dust from entering the room when cleaning the outer surface; when cleaning the inner and outer surfaces at the same time, the air flow rate of the first air hole 63 can be made smaller than the air flow rate of the second air hole 64, and debris and dust can be removed at the same time, and dust can be prevented from entering the room.

[0074] When cleaning the outer surfaces of multiple folding units 1, air is supplied to the first air cavity 61 by the air pump 8, and the multiple first blowing holes 63 connected to the first air cavity 61 can blow air toward the outer surfaces of the first window sheet 21 and the third window sheet 23. The outer surface is the surface in contact with the outside of the room. The direction in which the first blowing holes 63 are set can remove larger debris such as leaves attached to the folding units 1 when the multiple folding units 1 are at the maximum expansion angle (and the telescopic fixing part 6 is also expanded at the maximum angle); when cleaning the inner surfaces of the multiple folding units 1, air is supplied to the second air cavity 62 by the air pump 8, and the multiple second blowing holes 64 connected to the second air cavity 62 can blow air toward the inner surfaces of the first window sheet 21 and the third window sheet 23. The air flow will also blow toward the inner surface of the second window sheet 22. The inner surface is the surface in contact with the room. The direction in which the second blowing holes 64 are set can realize reverse cleaning of the multiple folding units 1 and blow out the dust attached to the screen window.

[0075] In one embodiment, a solution is provided for determining whether the multiple folding units 1 need to be cleaned;

[0076] Specifically, a pressure sensor is set on the surface of the mounting plate 43, the pressure sensor is connected to the control unit, and the control unit is connected to the control terminal via a wireless connection; the pressure sensor is used to sense the pressure when the outward-opening window frame 5 is closed to determine whether the multiple folding units 1 need to be cleaned.

[0077] The control terminal can be a mobile phone software. Each time the outward-opening window frame 5 is closed, the pressure value detected by the pressure sensor is transmitted to the control terminal in real time. If the detected pressure is greater than the first set pressure, an alarm prompt is issued through the mobile phone software, indicating that there may be foreign objects stuck on the multiple folding units 1 and need to be cleaned. If the detected pressure is less than or equal to the first set pressure, the outward-opening window frame 5 can be closed normally; wherein, the first set pressure is: under normal conditions, when there is no debris attached to the multiple folding units 1, the maximum pressure value detected by the pressure sensor.

[0078] Furthermore, the pressure sensor is also used to sense whether the outward-opening window frame 5 is opened to the maximum extension angle. When the pressure detected by the pressure sensor is less than a second set pressure, it indicates that the outward-opening window frame 5 is at the maximum extension angle. The second set pressure is: under normal conditions, when the outward-opening window frame 5 is opened to the maximum extension angle, the maximum pressure value detected by the pressure sensor;

[0079] Furthermore, the air pump 8, the three-way valve and the flow regulating valve can also be connected to the control unit, which can control the opening and closing of the air pump 8, and can record the working time and working cycle of the air pump 8. The working cycle can be set in the mobile phone software;

[0080] For example, if the working cycle is one week, the mobile phone software will remind the user that cleaning is required when the working cycle is over. The user needs to open the outward-opening window frame 5 to the maximum expansion angle. When the pressure sensor detects that the pressure is less than the second set pressure, the air pump 8 is automatically controlled to work and the folding screen window is cleaned regularly.
