[0011] By employing the above technical solution, this utility model provides a cleaning device for metal screen windows, which has at least the following beneficial effects:

[0012] 1. This metal screen cleaning device, by setting up a cleaning mechanism and a dust collection mechanism, has the cleaning mechanism contacting the screen and sweeping off the dust through the action of a roller brush. At the same time, when the fan in the dust collection mechanism rotates forward, it blows the dust on the screen to the outside by blowing air outward. When the fan rotates in reverse, it sucks the dust into the dust collection box, which can prevent the dust from spreading everywhere. It has the advantages of simple and convenient screen cleaning, and at the same time, it will not allow dust to fall into the room during cleaning, reducing subsequent cleaning steps and protecting the health of cleaning personnel.

[0013] 2. The cleaning device for this metal screen window is equipped with a wind direction detection mechanism. When the wind is blowing, the wind enters from one side of the north-south window and exits from the other. If the wind direction detection mechanism rotates clockwise, the airflow direction near that side window is from inside to outside. At this time, the fan can directly blow the dust outside when cleaning. On the other side window, the airflow direction is from outside to inside. At this time, the fan can reverse to suck the dust into its interior for storage. By detecting the airflow direction of the north-south windows of the house, the cleaning method can be adjusted according to the natural wind direction to ensure that the dust does not spread everywhere.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Metal screens are window screens made of metal materials (such as aluminum or stainless steel) used to prevent insects and debris from entering the room while maintaining ventilation. Compared to traditional screens, metal screens are more durable, corrosion-resistant, and can withstand wind and rain, making them suitable for various climatic conditions. They are typically installed on window frames and can be opened or fixed, with designs that can match the style of the windows. Metal screens are commonly used in residential, commercial, and industrial buildings, serving as an important facility for improving indoor comfort and security.

[0028] Example 1:

[0029] Due to the limitations of existing technologies, such as the inconvenience of cleaning window screens and the ease with which dust can be dispersed, please refer to... Figures 1-9 This utility model provides a metal screen cleaning device, which has the advantages of simple and convenient screen cleaning, while preventing dust from falling into the room during cleaning, reducing subsequent cleaning steps, and protecting the health of cleaning personnel. It includes an outer shell composed of an upper shell 1 and a lower shell 2. A cleaning mechanism 3 that contacts the screen is installed inside the lower shell 2. A dust collection mechanism 4 that works in conjunction with the cleaning mechanism 3 is installed inside the upper shell 1. A wind direction detection mechanism 5 is installed through the upper shell 1 and the lower shell 2. A handle 6 is fixed to the surface of the upper shell 1, and a switch button 7 is provided on the handle 6. In use, hold the device and place it against the screen, then press the switch button 7 to start the cleaning mechanism. Under the action of the wind direction detection mechanism 5, the rotation direction of the fan 404 is selected according to the airflow direction. If the wind direction is towards the outside, the fan 404 is used to blow air and blow the cleaned dust outside. If the wind direction is towards the inside, the fan 404 is reversed to suck the dust into the storage compartment.

[0030] To perform the cleaning operation on the window screens, please refer to... Figure 3 The cleaning mechanism 3 includes a roller brush 301 installed in the mounting groove at the bottom of the lower housing 2. The roller brush 301 is connected between the mounting assembly 302 and the driven wheel 303. The driven wheel 303 is rotatably connected in the lower housing 2 and is driven by the drive wheel 304 via a belt. The drive wheel 304 is fixed to the output shaft of the motor 305. The motor 305 operates and drives the roller brush 301 to rotate through the transmission action of the drive wheel 304 and the driven wheel 303. After the roller brush 301 contacts the screen window, it can clean the screen window through the rotation action.

[0031] To improve the cleaning effect of window screens, please refer to... Figure 5The roller brush 301 includes a roller shaft 3011, and brush bristles 3012 are provided on the outer wall of the roller shaft 3011. The ends of the brush bristles 3012 are provided with hook grooves 3013. During rotation, the brush bristles 301 with hook-like structures lie on the surface of the metal screen. The brush bristles 301 with hook-like structures can pass through the mesh of the metal screen. The hook-like structures can hook onto the mesh wires of the screen and apply a certain friction force, thereby sweeping the dust off the screen.

[0032] To replace roller brush 301, please refer to... Figure 4 The mounting assembly 302 includes a rotating cylinder 3022 rotatably mounted inside the lower housing 2 via a rotating shaft 502. A top post 3024 is elastically connected inside the rotating cylinder 3022 via a spring 3023. At least two positioning grooves 30241 are provided on the outer wall of one end of the top post 3024. One end of the top post 3024 is inserted into a slot opened at one end of the roller shaft 3011. The slot is provided with a positioning protrusion 30111 that matches the positioning groove 30241. There are two top posts 3024, and the other top post 3024 is fixedly connected to the driven wheel. Both ends of the roller brush 301 have slots. When replacing the roller brush 301, under the elastic force of the spring 3023, one end of the roller brush 301 presses against the top post 3024, and the top post 3024 retracts into the rotating cylinder 3022. At this time, space is left for disassembly of the other end of the roller brush 301. Conversely, the roller brush 301 can be installed using the same principle.

[0033] To collect dust, please refer to... Figures 8-9 The dust collection mechanism 4 includes a dust collection box 401 inserted into the upper housing 1. A box cover 402 is snapped onto the top of the dust collection box 401. An opening is provided on the side wall of the dust collection box 401, and an air guide hood 403 is attached to the opening. The air guide hood 403 is installed inside the upper housing 1. One end of the air guide hood 403 is embedded in a vent 201 opened on the inner wall of the mounting groove. A fan 404 is installed inside the upper housing 1 on one side of the dust collection box 401. A filter screen 405 is snapped onto the inner wall of the dust collection box 401 near the fan 404. When the wind is blowing, the wind direction is from one side of the north and south windows to the other side. If the wind direction detection mechanism 5 rotates clockwise, the airflow direction near the window on that side is from inside to outside. At this time, when cleaning, the fan 404 can directly blow the dust to the outside by rotating clockwise. The airflow direction of the other window is from outside to inside. At this time, the fan 404 can be reversed to suck the dust into its interior for storage.

[0034] It should also be noted that since the setting of the filter screen 405 may affect the blowing effect of the fan 404, an additional fan can be installed in the lower housing in actual application. When dust blowing is required, the added fan can be used.

[0035] Example 2:

[0036] To detect wind direction, please refer to... Figure 6 The wind direction detection mechanism includes a ventilation pipe 501 installed between the upper housing 1 and the lower housing 2. A rotating shaft 502 is rotatably connected inside the ventilation pipe 501. Multiple sets of air guide vanes 503 are fixed on the outer wall of the rotating shaft 502. An arrow mark is provided on the top of the rotating shaft 502. When the airflow enters the ventilation pipe 501, it can drive the rotating shaft 502 to rotate under the action of the air guide vanes 503. At this time, the rotation direction of the rotating shaft 502 can be clearly seen through the arrow mark, so as to understand the wind direction and select the cleaning method according to the wind direction.

[0037] To facilitate the intake or exhaust of air, a second air hole 8 is provided on the side wall of the upper shell 1 near the tail. When blowing dust outward, air enters through the second air hole 8 and exits through the first air hole 201. Conversely, when sucking dust inward, air enters through the first air hole 201 and exits through the second air hole 8.
