DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an external screen window that is easy to clean, comprising a window frame 1 and a screen 3, the window frame 1 is fixed on the window frame, a top box 2 is fixed on the top of the window frame 1, a winding shaft 7 is movably connected inside the top box 2, and a torsion spring 701 is arranged between the winding shaft 7 and the top box 2, the top of the screen 3 is wound on the shaft body of the winding shaft 7, and the bottom of the screen 3 is plugged and fixed to the window frame 1. Specifically, the fixing method of the bottom of the screen 3 and the window frame 1 can also be selected as a latch connection or other locking connection. In the initial state, the bottom of the screen 3 is fixed to the bottom of the window frame 1, and the screen 3 is in a closed state. When the screen window needs to be opened, the lock between the screen 3 and the window frame 1 is released, and under the action of the torsion spring 701, the winding shaft 7 winds the screen 3, and the screen 3 slides upward. The above is a mature existing technology and will not be repeated in this solution.

[0026] A cleaning component is provided on the left side of the top box 2, and impurities adhered to the surface of the gauze 3 are cleaned by the cleaning component. A dust collecting box 5 is plugged into the bottom of the cleaning component, and a handle is fixed on the side of the dust collecting box 5. The dust collecting box 5 is pulled out of the top box 2 by the handle, and the dust collecting box 5 collects the cleaned impurities. A dust exhaust component 4 is provided on the right side of the top box 2, and dust generated during cleaning is discharged to the outside through the dust exhaust component 4. Specifically, in this solution, the pulling direction of the dust collecting box 5 is the indoor direction, and the opposite direction is the outdoor direction.

[0027] like Figure 4 As shown, a bottom plate 201 is formed at the bottom of the top box 2, and a rectangular through groove is opened on the plate body of the bottom plate 201, and the gauze 3 is movably arranged in the rectangular through groove, and the bottom plate body of the dust collecting box 5 is in contact with the top end surface of the bottom plate 201.

[0028] like Figure 4As shown, the cleaning component includes a fixing frame 801 fixed to the inner wall of the side of the top box 2, and a plurality of nail-type plug rods 802 are movably inserted on the fixing frame 801, and a spring 803 is connected between the nail-type plug rod 802 and the fixing frame 801, and an inclined plate 804 is fixed to the end of the nail-type plug rod 802, and a plurality of bristles 805 in contact with the surface of the screen 3 are fixed to the side of the inclined plate 804. It can be understood that when the window screen 3 is rolled up, the top window screen 3 close to the winding shaft 7 will gradually move to the left, and the window screen 3 will be squeezed by the bristles 805. Under this squeezing force, the nail-type plug rod 802 moves to the left and the spring 803 extends. The setting of the cleaning component in this scheme will not only not interfere with the rolling of the window screen 3, but also make the bristles 805 fully contact with the surface of the window screen 3, thereby improving the cleaning effect. In addition, it is also necessary to understand that the thickness of the window screen 3 is relatively small, and the bristles 805 can clean the inside and outside of the window screen 3 at the same time when scraping the front of the window screen 3.

[0029] To facilitate the disassembly and assembly of the top box 2, grooves 601 are provided on both sides of the bottom of the top box 2, a second magnet is fixed in the groove 601, and a first magnet 602 is fixed on both sides of the dust collection box 5, and the first magnet 602 and the opposite sides of the second magnet attract each other.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, the dust exhaust component 4 includes air outlets opened on both sides of the top box 2 and first bevel gears 401 fixed on both sides of the winding shaft 7, the side of the first bevel gear 401 is meshed with a second bevel gear 402, a fixed shaft is fixed to the side of the second bevel gear 402, and a support frame 403 is movably connected to the shaft body of the fixed shaft, a fan 404 is fixed to the other end of the fixed shaft, and the fan 404 is located in the air outlet. In order to increase the rotation speed of the fan 404 and improve the dust exhaust effect, in this solution, the gear ratio of the first bevel gear 401 and the second bevel gear 402 is 1: (0.2-1).

[0031] To supplement the present solution, when cleaning the window screen, the lock between the screen 3 and the window frame 1 is released, and under the action of the torsion spring 701, the winding shaft 7 winds the screen 3, and the screen 3 moves upward. When the screen 3 is upward, the bristles 805 are in full contact with the surface of the window screen 3, thereby scraping the impurities attached to the surface of the screen 3 off the screen 3, and the large impurities enter the dust collection box 5. When the winding shaft 7 rotates, it drives the first bevel gear 401 and the second bevel gear 402 to rotate, thereby driving the fan 404 to rotate through the fixed shaft. At this time, there is a negative pressure in the top box 2, and the dust in the top box 2 is discharged to the outside through the fan 404.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
