Description

Technical Field

[0001] This utility model relates to the field of door and window cleaning technology, and in particular to a timed cleaning device for aluminum alloy doors and windows. Background Technology

[0002] As people's living standards continue to improve, their requirements for living environment are also getting higher and higher. As an important part of buildings, doors and windows play an important role in daily life. However, traditional manual cleaning methods are not only inefficient but also prone to safety hazards. A timed cleaning device for aluminum alloy doors and windows combines mechanical transmission structure with timed control technology to achieve timed and automatic cleaning of the glass and frame surfaces of doors and windows.

[0003] A search revealed Chinese Patent Publication No. CN221888157U, which discloses a door and window with a self-cleaning function, relating to the field of door and window technology. This utility model includes a window frame, and the cleaning device includes a grooved rod. One side of the grooved rod is fixedly connected to one side of the sash frame. A sliding groove is formed inside the groove, and a motor is installed at the top of the inner wall of the sliding groove. A screw is fixedly connected to the output end of the motor, and a slider is threaded onto the outer surface of the screw. A connecting rod is fixedly connected to one end of the slider, and several sponge strips are provided on one side of the connecting rod. This utility model... The cleaning device is set up by inputting the timer trigger parameters into the database via the control panel. When the timer parameters are triggered, the motor is controlled to operate. The motor drives the screw to rotate, causing the slider to move up and down on the inner wall of the slide. This drives the connecting rod to move, and several sponge strips on one side of the connecting rod scrape and clean the outer surface of the glass plate, achieving regular self-cleaning of doors and windows and increasing the convenience of using doors and windows. However, because the sponge strips scrape and clean by rotating the screw forward and backward via the motor, the scraped dust will accumulate at the bottom of the window frame and cannot be completely cleaned, which does not meet the needs of users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a timed cleaning device for aluminum alloy doors and windows, which aims to improve the problem in the prior art where the scraped dust accumulates at the bottom of the window frame due to the sponge strip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a timed cleaning device for aluminum alloy doors and windows, including a sash frame, a reciprocating cleaning mechanism provided at the rear left end of the sash frame, and a fixing mechanism provided at the rear right end of the sash frame. The reciprocating cleaning mechanism includes a housing and a transmission belt. The front side of the housing is fixedly connected to the rear left end of the fan frame. The upper and lower ends of the left side of the inner wall of the housing are rotatably connected to transmission wheels. The two transmission wheels are connected by transmission belt. A motor is fixedly connected to the top left end of the housing. The output end of the motor passes through the left end of the housing and is fixedly connected to the left end of the corresponding transmission wheel. A connecting block is fixedly connected to the upper middle part of the rear side of the outer wall of the transmission belt. A connecting plate is slidably connected to the upper middle part of the inner wall of the housing. A groove is opened on the left side of the connecting plate. The right end of the connecting block is slidably connected to the inside of the groove. A connecting shaft is rotatably connected to the right end of the connecting plate. A brush roller is slidably connected to the right side of the outer wall of the connecting shaft. A rotating component is provided on the outer wall of the connecting shaft.

[0006] Through the above technical solution: the motor drives the upper transmission wheel to rotate, and the transmission belt links the lower transmission wheel to form a closed-loop transmission, so that the connecting block on the outer wall of the transmission belt moves in a circular motion with the transmission belt. The connecting block is embedded in the sliding groove on the left side of the connecting plate, which converts the circular motion into the vertical sliding of the connecting plate, thereby driving the connecting shaft and the brush roller to move up and down reciprocally, so as to achieve full-height coverage cleaning of the surface of doors and windows.

[0007] As a further description of the above technical solution: the fixing mechanism includes a bushing, the inner wall of the bushing is slidably connected to the right side of the outer wall of the brush roller, the outer wall of the bushing is provided with a connecting sleeve, the outer wall of the bushing is rotatably connected to the inner wall of the connecting sleeve, a through hole one is opened on the left side of the outer wall of the bushing, a through hole two is opened on the right side of the outer wall of the brush roller, the inner walls of the through hole one and the through hole two are threaded with the same bolt, and an auxiliary moving component is provided on the front side of the connecting sleeve.

[0008] The above technical solution involves a bushing that slides onto the outer wall of the right end of the brush roller, providing radial support for the brush roller and allowing it to rotate freely through rotational engagement with the connecting sleeve. The bolts, threaded through through holes one and two, enable the bushing and brush roller to be quickly fixed together.

[0009] As a further description of the above technical solution: the rotating component includes a gear, the inner wall of the gear is fixedly connected to the left side of the outer wall of the connecting shaft, and a rack is fixedly connected to the right end of the front side of the inner wall of the housing, and the gear and the rack are meshed together.

[0010] With the above technical solution: after the gear is fixed to the connecting shaft, it moves up and down with the gear. Since the gear is always meshed with the rack fixed on the front side of the housing, when the connecting plate drives the connecting shaft to move up and down, the gear rolls along the rack and generates its own rotation, thereby driving the connecting shaft to rotate.

[0011] As a further description of the above technical solution: the auxiliary moving component includes a slider, the rear side of which is fixedly connected to the front side of the connecting sleeve, a slide rail is fixedly connected to the rear right end of the fan frame, and the inner side of the slider is slidably connected to the outer side of the slide rail.

[0012] With the above technical solution: after the slider and the connecting sleeve are fixed, they are embedded in the slide rail at the right end of the fan frame to form a sliding pair. When the brush roller moves up and down, the slider slides synchronously along the slide rail to provide precise guidance for the right end of the brush roller.

[0013] As a further description of the above technical solution: guide grooves are provided on both the front and rear sides of the inner wall of the housing, and the front and rear ends of the connecting plate are respectively slidably connected to the interior of the corresponding guide grooves.

[0014] Through the above technical solution: the guide grooves on the front and rear sides of the inner wall of the housing form a sliding fit with the front and rear ends of the connecting plate, and the movement freedom of the connecting plate is restricted by the groove wall.

[0015] As a further description of the above technical solution: a cover plate is rotatably connected to the upper middle part of the front left end of the fan frame, and a timing controller is provided in the middle of the front left end of the fan frame.

[0016] The above technical solution involves a cover plate that is rotatably connected to the front of the fan frame. When closed, it covers the timer controller, blocking dust, water droplets, and external impacts, thus protecting the internal circuitry of the controller. When open, it exposes the operating interface, making it convenient for users to set cleaning times.

[0017] As a further description of the above technical solution: the outer wall of the fan frame is provided with a window frame, and hinges are fixedly connected to the upper and lower sides of the front left end of the fan frame. The fan frame is rotatably connected to the window frame through the hinges, and a handle is fixedly connected to the front right end of the window frame.

[0018] The above technical solution involves a sash frame that is rotatably connected to the window frame via upper and lower hinges. The hinges allow the sash frame to rotate around them, enabling the opening and closing of the doors and windows. The handle provides a fulcrum for force application, allowing for easy operation of the sash frame's opening and closing through the lever principle.

[0019] As a further description of the above technical solution: a limiting post is fixedly connected to the right side of the outer wall of the connecting shaft, and a limiting groove is opened on the inner wall of the brush roller, with the limiting post engaging with the limiting groove.

[0020] The above technical solution ensures that when the connecting shaft rotates, the limiting post transmits torque through the groove wall, thus ensuring that the brush roller rotates synchronously with the connecting shaft.

[0021] In summary, 1. In this utility model, the motor causes the two transmission wheels to rotate synchronously through the transmission belt. The connecting block on the outer wall of the transmission belt moves synchronously and cyclically with the transmission belt. The cyclical motion of the connecting block is converted into the stable up-and-down reciprocating sliding of the connecting plate along the guide groove. At the same time, the gear rolls along the rack with the up-and-down movement of the connecting plate, thereby causing the brush roller to rotate while moving up and down, so as to achieve full coverage cleaning of the surface of the door and window by the brush roller, and avoid dust being pushed to the bottom and accumulated in one direction.

[0022] 2. In this utility model, when installing the brush roller, first connect the brush roller and the connecting shaft by engaging the limiting post and the limiting groove, then slide the bushing along the outer wall of the right side of the brush roller, so that the first through hole of the bushing is aligned with the second through hole of the brush roller, and tighten a single bolt through the two through holes. This achieves rigid fixation of the bushing and the brush roller through the threaded connection, thus completing the positioning of the brush roller. Attached Figure Description

[0025] 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.

[0026] Reference Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a timed cleaning device for aluminum alloy doors and windows, including a sash frame 1, a reciprocating cleaning mechanism 2 provided at the rear left end of the sash frame 1, and a fixing mechanism 3 provided at the rear right end of the sash frame 1. The reciprocating cleaning mechanism 2 includes a housing 201 and a transmission belt 204. The front side of the housing 201 is fixedly connected to the rear left end of the fan frame 1. The housing 201 serves as the mounting base for the entire reciprocating cleaning mechanism 2. Transmission wheels 202 are rotatably connected to the upper and lower ends of the left side of the inner wall of the housing 201. The two transmission wheels 202 are connected by the transmission belt 204, which is sleeved between the two transmission wheels 202, forming a power transmission medium. A motor 203 is fixedly connected to the top left end of the housing 201. The motor 203 is the power source, and its output end passes through the left end of the housing 201 and is fixedly connected to the left end of the corresponding transmission wheel 202. A connecting block 205 is fixedly connected to the upper middle part of the rear side of the outer wall of the transmission belt 204. The connecting block 205 moves synchronously with the transmission belt 204 in a circular motion. A connecting plate 206 is slidably connected to the upper part of the inner wall of the housing 201. The connecting plate 206 is an intermediate transmission component. A sliding groove 207 is provided on the left side of the connecting plate 206. The sliding groove 207 allows the connecting block 205 to slide horizontally in the groove and can transmit longitudinal force through the groove wall, driving the connecting plate 206 to move up and down synchronously with the connecting block 205. The right end of the connecting block 205 is slidably connected to the inside of the sliding groove 207. A connecting shaft 208 is rotatably connected to the right end of the connecting plate 206. A brush roller 209 is slidably connected to the right side of the outer wall of the connecting shaft 208. The brush roller 209 is a direct cleaning component. A rotating component 210 is provided on the outer wall of the connecting shaft 208. The rotating assembly 210 includes a gear 2101. The inner wall of the gear 2101 is fixedly connected to the left side of the outer wall of the connecting shaft 208. A rack 2102 is fixedly connected to the right end of the front side of the inner wall of the housing 201. The gear 2101 and the rack 2102 are meshed together. When the connecting plate 206 drives the connecting shaft 208 to move up and down, the gear 2101 rolls along the rack 2102 and rotates, converting linear motion into rotational motion of the connecting shaft 208. This ensures that the brush roller 209 rotates synchronously while moving, thus improving cleaning efficiency. Guide grooves 4 are provided on the front and rear sides of the inner wall of the housing 201. The front and rear ends of the connecting plate 206 are slidably connected to the interior of the corresponding guide grooves 4. The guide grooves 4 restrict the degree of freedom of movement of the connecting plate 206, allowing it to slide up and down in the vertical direction only. A limiting post 10 is fixedly connected to the right side of the outer wall of the connecting shaft 208, and a limiting groove 11 is opened on the inner wall of the brush roller 209. The limiting post 10 and the limiting groove 11 are engaged. When the connecting shaft 208 rotates, the limiting post 10 transmits torque through the groove wall, causing the brush roller 209 to rotate synchronously. Specifically, when the device is started, the motor 203 of the reciprocating cleaning mechanism 2 outputs power, causing the transmission wheel 202 connected to the output shaft to rotate. This rotation, via the transmission belt 204, drives the lower transmission wheel 202 to rotate synchronously. The connecting block 205 on the outer wall of the transmission belt 204 moves synchronously in a circular motion with the transmission belt 204. Because the connecting block 205 is embedded in the sliding groove 207 on the left side of the connecting plate 206, and the front and rear ends of the connecting plate 206 are restricted by the guide groove 4 on the inner wall of the housing 201, the circular motion of the connecting block 205 is converted into the stable up-and-down reciprocating sliding of the connecting plate 206 along the guide groove 4. This achieves comprehensive cleaning of the door and window surfaces by the brush roller 209. Simultaneously, when the connecting plate 206 drives the connecting shaft 208 upwards... When moving downwards, the gear 2101 on the left side of the connecting shaft 208 continuously meshes with the fixed rack 2102. The gear 2101 rolls along the rack 2102 as the connecting plate 206 moves up and down, thereby driving the connecting shaft 208 to rotate. The connecting shaft 208 engages with the limiting groove 11 on the inner wall of the brush roller 209 through the limiting post 10 on the outer wall, transmitting the rotational force to the brush roller 209. This allows the brush roller 209 to rotate while moving up and down. The rotational motion of the brush roller 209 can separate the dust on the window surface from the attachment point through the circumferential motion of the bristles, rather than simply pushing it. At the same time, its reciprocating up and down movement ensures that the bristles can cover the entire area of ​​the door and window, preventing the dust from being pushed to the bottom and accumulating in one direction.

[0027] Reference Figure 3 , Figure 4 and Figure 5 The fixing mechanism 3 includes a bushing 301. The inner wall of the bushing 301 is slidably connected to the right side of the outer wall of the brush roller 209. A connecting sleeve 302 is provided on the outer wall of the bushing 301. The connecting sleeve 302 provides stable support for the brush roller 209. The outer wall of the bushing 301 is rotatably connected to the inner wall of the connecting sleeve 302. A through hole 303 is provided on the left side of the outer wall of the bushing 301. A through hole 304 is provided on the right side of the outer wall of the brush roller 209. The inner walls of the through holes 303 and 304 are threadedly connected to the same bolt 305. After the through hole 303 on the left side of the bushing 301 is aligned with the through hole 304 on the brush roller 209, a rigid connection is achieved by the bolt 305 to ensure that the two move synchronously. An auxiliary moving component 306 is provided on the front side of the connecting sleeve 302. The auxiliary moving component 306 includes a slider 3061, which reduces sliding friction resistance and ensures that the brush roller 209 moves smoothly up and down. The rear side of the slider 3061 is fixedly connected to the front side of the connecting sleeve 302. The rear right end of the fan frame 1 is fixedly connected to the slide rail 3062, and the inner side of the slider 3061 is slidably connected to the outer side of the slide rail 3062. Specifically, when installing the brush roller 209, firstly, the brush roller 209 and the connecting shaft 208 are engaged and connected via the limiting post 10 and the limiting groove 11. Next, the bushing 301 is slid into the outer wall of the right side of the brush roller 209, aligning the first through hole 303 of the bushing 301 with the second through hole 304 of the brush roller 209. Then, a single bolt 305 is passed through these two through holes and tightened. This achieves a rigid fixation between the bushing 301 and the brush roller 209 through a threaded connection, thus completing the positioning of the brush roller 209. This process simplifies the installation steps. When replacing the brush roller 209, only the bolt 305 passing through the first through hole 303 and the second through hole 304 needs to be unscrewed, and the bushing 301 is slid into the outer wall of the right side of the brush roller 209. The outer wall of the brush roller 209 can be detached from the connecting shaft 208 to complete the disassembly. This improves the convenience of operation. The outer wall of the bushing 301 is rotatably connected to the inner wall of the connecting sleeve 302. When the brush roller 209 rotates with the connecting shaft 208, the bushing 301 rotates synchronously while the connecting sleeve 302 remains stationary to avoid interference with the rotation. The slider 3061 on the front side of the connecting sleeve 302 is embedded in the slide rail 3062 on the right side of the fan frame 1. When the brush roller 209 moves up and down with the reciprocating cleaning mechanism 2, the slider 3061 slides synchronously along the slide rail 3062. The guide effect of the slide rail 3062 restricts the wobbling of the right end of the brush roller 209 and ensures its fitting accuracy with the window surface.

[0028] Reference Figure 1 and Figure 2 A cover plate 5 is rotatably connected to the upper middle part of the front left side of the fan frame 1. The cover plate 5 forms a physical protective barrier. A timer controller 6 is set in the middle of the front left side of the fan frame 1. It is connected to the motor 203 and the power supply through wires. It can preset the cleaning time period and adjust the speed of the motor 203. A window frame 7 is provided on the outer wall of the sash frame 1. The window frame 7 is the mounting base of the sash frame 1. Hinges 8 are fixedly connected to the upper and lower sides of the front left end of the sash frame 1. The sash frame 1 is rotatably connected to the window frame 7 through the hinges 8. A handle 9 is fixedly connected to the front right end of the window frame 7. The handle 9 provides a force fulcrum. Specifically, when the cover 5 is closed, it covers the outside of the timer controller 6, forming a physical barrier to block dust, rain or external force from directly impacting the controller and protecting the internal circuit components. When it is necessary to set the cleaning time, flipping the cover 5 will expose the controller operation interface. The handle 9 serves as the force point. By holding the handle 9 and pushing or pulling, the fan frame 1 will rotate around the hinge 8, thereby opening and closing the door and window.

[0029] Working principle: When the device is started, the motor 203 of the reciprocating cleaning mechanism 2 outputs power, causing the transmission wheel 202 connected to the output shaft to rotate. This rotation is synchronized with the lower transmission wheel 202 via the transmission belt 204. The connecting block 205 on the outer wall of the transmission belt 204 moves synchronously with the transmission belt 204. Because the connecting block 205 is embedded in the sliding groove 207 on the left side of the connecting plate 206, and the front and rear ends of the connecting plate 206 are limited by the guide groove 4 on the inner wall of the housing 201, the cyclic motion of the connecting block 205 is converted into the stable up-and-down reciprocating sliding of the connecting plate 206 along the guide groove 4. This achieves full coverage cleaning of the door and window surfaces by the brush roller 209. Simultaneously, the connecting plate 206 drives the connecting shaft 208 upwards... When moving downwards, the gear 2101 on the left side of the connecting shaft 208 continuously meshes with the fixed rack 2102. The gear 2101 rolls along the rack 2102 as the connecting plate 206 moves up and down, thereby driving the connecting shaft 208 to rotate. The connecting shaft 208 engages with the limiting groove 11 on the inner wall of the brush roller 209 through the limiting post 10 on the outer wall, transmitting the rotational force to the brush roller 209, so that the brush roller 209 can rotate itself while moving up and down. The rotational motion of the brush roller 209 can peel the dust off the window surface from the attachment point through the circumferential motion of the bristles, rather than simply pushing it. At the same time, the up-and-down reciprocating movement ensures that the bristles cover the entire area of ​​the door and window, preventing the dust from being pushed to the bottom and accumulating in one direction. Furthermore, when installing the brush roller 209, first connect the brush roller 209 and the connecting shaft 208 by engaging the limiting post 10 and the limiting groove 11. Then, slide the bushing 301 along the outer right side of the brush roller 209, aligning the first through hole 303 of the bushing 301 with the second through hole 304 of the brush roller 209. Tighten the single bolt 305 through both through holes, thus achieving rigid fixation of the bushing 301 and the brush roller 209 through the threaded connection, completing the positioning of the brush roller 209 and simplifying the installation steps. When replacing the brush roller 209, simply unscrew the bolt 305 that passes through the first through hole 303 and the second through hole 304, slide the bushing 301 away along the outer wall of the brush roller 209, thus releasing the right end fixation. Then, pull the brush roller 209 out of the connecting shaft 208 to complete the disassembly, improving the ease of operation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
