Description

Technical Field

[0001] This utility model relates to the field of screen cleaning technology, specifically, to a screen cleaning device. Background Technology

[0002] Diamond-coated window screens are widely used in residences, office buildings, hospitals, and other settings. However, after prolonged use, these screens are prone to accumulating dust and lint from the air. Regular cleaning not only eliminates the ventilation bottleneck caused by dust buildup but also effectively removes accumulated bacteria, mites, and other microbial contaminants, ensuring better indoor air quality. Traditional cleaning methods for diamond-coated window screens primarily involve manual wiping or mopping with a cotton mop.

[0003] However, traditional cleaning methods have the following problems: 1. Due to the porous nature of window screens, water stains and contaminants are easily squeezed to the back of the screen during manual wiping, making thorough cleaning impossible; 2. Manual cleaning often uses wet wiping tools, and the wastewater generated from cleaning the screens causes secondary pollution to the interior or windowsill; 3. Cleaning the outside of the screen is inconvenient, and if one leans out to clean it, there may be safety risks due to the floor level. Therefore, it is necessary to design a window screen cleaning device that can switch between indoor and outdoor operation modes. Summary of the Invention

[0042] In this embodiment, the main rod 1 is a two-section telescopic rod.

[0043] The cleaning steps of this utility model are as follows:

[0044] Step 1: Push the slider 2 to the corresponding position according to the desired cleaning state:

[0045] When the indoor side of the screen window 300 needs to be cleaned, push the slider 2 down to make the lower elastic buckle 102 engage with the lower buckle hole 202, and the dirt collection cover 6 flips to the front of the brush roller 11.

[0046] When the outdoor side of the screen window 300 needs to be cleaned, push the slider 2 upward to make the upper elastic buckle 101 engage with the upper buckle hole 201, and the dirt collection cover 6 flips to the back side of the brush roller 11.

[0047] Step 2: Place the screen 300 in the gap between the dirt collection cover 6 and the brush roller 11, so that the sponge strip 26 is close to the screen 300 and the brush roller 11 is in contact with the screen 300.

[0048] Step 3: Control the direction of motor 21 according to the cleaning status, thereby driving brush roller 11 to rotate and rub against the surface of window screen 300; at the same time, turn on water pump 20, connect external water source, and the cleaning water enters water spray pipe 23 through water outlet pipe 2001 and is sprayed out from nozzle 12 to achieve cleaning on the corresponding side.

[0049] During cleaning, most of the sewage enters the sewage collection hood 6, and the corresponding sewage pump 9 is turned on. The sewage passes through the corresponding sewage collection pipe 24, three-way valve 8, sewage delivery pipe 25 in sequence, and finally is discharged into the sewage collector through the sewage discharge pipe 2002. A small portion of the sewage flows down along the screen window 300 and is absorbed by the sponge strip 26.
