[0018] The utility model is now further described with reference to the accompanying drawings.

[0019] like Figures 1 to 6 An automatic liquid-discharging window wiper shown in the figure comprises a first shell 1 and a second shell 2 connected to each other, a cavity is formed between the first shell 1 and the second shell 2, a telescopic plug 3 is provided in the cavity, two protruding parts and a scraper strip 4 are provided on the outside of the first shell 1, a through hole 1a is provided on the first shell 1, a gap is provided between the telescopic plug 3 and the through hole 1a, the telescopic plug 3 in the cavity can extend from the through hole 1a to the outside of the first shell 1 and seal the through hole 1a, the telescopic plug 3 can be retracted into the cavity to open the gap between the telescopic plug 3 and the through hole 1a, and the telescopic plug 3 and the two protruding parts are distributed in a triangle.

[0020] The method of using the utility model is to store clean water or cleaning liquid through the cavity, and then face the first shell 1 to the glass and press it against the glass. Because the two protruding parts on the first shell 1 and the telescopic plug 3 are distributed in a triangle, the two protruding parts can form a fulcrum, so that the entire window cleaner deflects toward the glass around the fulcrum, thereby pressing the telescopic plug 3 to retract it into the cavity, so that the water or cleaning liquid in the cavity can flow outward onto the glass through the gap between the telescopic plug 3 and the through hole 1a, thereby achieving the effect of wetting the glass and facilitating the cleaning of the glass.

[0021] As a preferred embodiment, the utility model installs a magnet in the cavity (not shown in the figure). After the magnet is installed, in conjunction with the magnetic device, the automatic liquid-discharging window cleaner of the utility model can be placed outdoors and operated by the magnetic device indoors.

[0022] As a preferred embodiment, the raised component includes a roller 5, which is mounted on the first housing 1 and partially protrudes from the surface of the first housing 1. In addition to the roller 5, the raised component can also be a protrusion integrally formed on the outer surface of the first housing 1, but the friction between the fixed protrusion and the glass may scratch the glass, so the roller 5 is preferably used.

[0023] As a preferred embodiment, the scraper strip 4 has a T-shaped cross section, and a matching T-slot 6 is provided on the surface of the first housing 1. The scraper strip 4 is inserted into the T-slot 6 from the side of the first housing 1 for fixation. In addition to this method, the scraper strip 6 can also be fixed by bonding, screws, etc., but fixing with the T-slot 6 is the simplest and convenient for replacing the scraper strip 4.

[0024] As a preferred embodiment, the T-slot 6 is provided with an elastic side wall 7, on which a snap-fitting opening 7a is provided, and the side surface of the scraper strip 4 is provided with a corresponding snap-fitting portion 4a protruding outward. After the scraper strip 4 is inserted into the T-slot 6, the snap-fitting portion 4a engages with the snap-fitting opening 7a to lock the scraper strip 4, thereby preventing the scraper strip 4 from moving laterally.

[0025] As a preferred embodiment, the telescopic plug 3 includes a fixed guide column 3a fixed inside the second shell 2, and a movable sleeve 3b sleeved on the fixed guide column 3a, the movable sleeve 3b can be displaced relative to the fixed guide column 3a, a spring 3c is provided between the movable sleeve 3b and the second shell 2, the movable sleeve 3b is provided with a stepped table 3d, and a sealing ring 8 is provided on the stepped table 3d. Under the action of the spring 3c, the front end of the movable sleeve 3b is inserted into the through hole 1a, and the sealing ring 8 on the stepped table 3d is pressed against the inner end surface of the through hole 1a to seal the gap.

[0026] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
