Description
Technical Field
[0001] This invention relates to window cleaning devices, and more particularly to fixed automatic window cleaning devices. Background Technology
[0002] As urban construction progresses, more and more office buildings and high-rise buildings are springing up, making window cleaning increasingly difficult. Cleaning outdoor windows is a challenging and dangerous task. Currently, the main method is for people to lean out of the window with a rag in hand to wipe the exterior glass. This is not only dangerous and unsafe, but also doesn't guarantee the window will be clean. Furthermore, for safety reasons, many windows now prohibit people from leaning out, and ordinary window cleaning methods simply cannot reach the outer side of the glass. Another commonly used method involves using magnets to hold two cleaning blocks, one inside the window and one outside. The person grabs the inner block and moves it, causing the outer block to move accordingly. This method is entirely manual, requiring considerable force to repeatedly move the cleaning blocks, consuming a lot of physical strength that is difficult for the average person to endure. Summary of the Invention
[0003] The present invention aims to solve the problems existing in the prior art by providing a fixed automatic window cleaning device that can not only clean windows automatically, saving time and effort, but is also safe and reliable.
[0004] The technical solution adopted by this invention to solve its technical problem is as follows: This fixed automatic window cleaning device includes a rack, a gear meshing at the right end of the rack, a rotating shaft fixedly connected to the rear end of the gear, a motor fixedly connected to the rear end of the rotating shaft, a guide rail fixedly connected to the rear end of the rack, a slider slidably connected to the outer side of the guide rail, a motor fixedly connected to the right end of the slider, a mounting block fixedly connected to the rear end of the slider, a first connecting rod mounted at the rear end of the mounting block, one end of a second connecting rod mounted at the rear end of the first connecting rod, a sliding block mounted at the other end of the second connecting rod, a mounting plate mounted on the sliding block, and a rubber pad mounted at the front end of the mounting plate. The scraper blade, driven by a motor, rotates a gear. Due to the rack and pinion mechanism, the rotating gear moves along the rack, which in turn moves the motor. The motor then moves a slider, which in turn moves a mounting block. The mounting block then moves a first connecting rod, which in turn moves a second connecting rod. The second connecting rod then moves a sliding block, which in turn moves a mounting plate. The mounting plate then moves the rubber scraper blade, which wipes the window, thus achieving automatic window cleaning. Rubber scraper blades of different widths can be installed to clean window glass of varying widths.
[0005] To further improve the system, the first connecting rod is rotatably connected to the second connecting rod, and the second connecting rod is rotatably connected to the sliding block. A groove is opened at the rear end of the mounting plate, and the sliding block is slidably connected in the groove. The first connecting rod and the second connecting rod are connected by a tension spring, which can automatically adjust the position of the mounting plate so that the rubber scraper can always be in close contact with the window glass, resulting in better cleaning effect and a wider range of applications for the device.
[0006] Further improvements include the addition of baffles fixedly connected to both the upper and lower ends of the guide rail, with a button fixedly connected to the right end of each baffle. A forward rotation button is installed on the upper end of the motor, and a reverse rotation button is installed on the lower end. The baffles prevent the slider from deviating from the path, and the buttons allow the motor to automatically switch between forward and reverse rotation by pressing the forward and reverse rotation buttons. When the lengths of the window glass are inconsistent, only guide rails of different lengths need to be customized, without changing the motor control, making the device more convenient to use.
[0007] Further improvements include a rotating hole at the rear end of the mounting block, with a rotating shaft rotatably connected within the hole. The rotating shaft is fixedly connected to the front end of the first connecting rod, and a fixing block is fixedly connected to the right end of the first connecting rod. A screw is threadedly connected to the fixing block, and a handle is fixedly connected to the rear end of the screw. Threaded holes are provided at both ends of the rotating hole at the rear end of the mounting block, and the screw is threadedly connected to these holes. This allows the mounting plate to rotate from the left to the right to wipe the glass on the right side, broadening the device's applicability, improving its functionality, and better meeting market demands.
[0008] To further improve the design, a dustproof box is fixedly connected to the lower end of the motor on the outside of the gear, preventing the gear from being exposed to the outside and increasing the service life of the device.
[0009] Further improvements include: a cam fixedly connected to the outer side of the rotating shaft; a water cylinder fixedly connected to the upper end of the dustproof box; a water inlet at the upper end of the water cylinder; a first one-way valve installed inside the water inlet; a water inlet pipe fixedly connected to the water inlet; a water outlet at the upper end of the water cylinder; a second one-way valve installed inside the water outlet; a water outlet pipe fixedly connected to the water outlet; a spray tank fixedly connected to the water outlet pipe; the spray tank mounted on the upper end of the mounting plate; a nozzle installed at the front end of the spray tank; a piston block slidably connected inside the water cylinder; a piston rod fixedly connected to the lower end of the piston block; the piston rod penetrating the inside of the dustproof box; a push block fixedly connected to the lower end of the piston rod; one end of a spring fixedly connected to the upper end of the push block; and the other end of the spring fixedly connected to the lower end of the water cylinder. The rotation of the cam drives the push block to move up and down, which in turn drives the piston rod to move up and down, which in turn drives the piston block to move up and down. Due to the action of the one-way valve, water is drawn from the water inlet pipe into the water tank, then flows from the water cylinder through the water outlet pipe into the spray tank, and finally sprayed out from the nozzle to clean the windows.
[0010] Further improvements include the addition of several nozzles that are evenly distributed at equal intervals, resulting in more uniform water spraying and better cleaning performance.
[0011] Further improvements include a water tank detachably connected to the upper end of the water inlet pipe, a connecting block fixedly connected to the right end of the motor, and the water tank detachably connected to the upper end of the connecting block. The design of the water tank makes the device more convenient to use.
[0012] Further improvements include a snap-fit block fixedly connected to the lower end of the water tank, and snap-fit grooves at both the upper and lower ends of the mounting plate. The snap-fit block snaps into the snap-fit grooves, allowing the water tank to be installed on the upper end of the mounting plate when the mounting plate is rotated from the left to the right, making cleaning more convenient.
[0013] To further improve the design, a protrusion is fixedly connected to the outside of the throttle, and there are several protrusions that are evenly distributed at equal intervals, making it more convenient to turn the throttle.
[0014] The beneficial effects of this invention are: it not only automatically cleans windows, saving time and effort, but is also safe and reliable. The motor rotates, driving the gears. Due to the rack and pinion mechanism, the gears move along the rack, which in turn moves the motor. The motor then moves the slider, which in turn moves the mounting block. The mounting block moves the first connecting rod, which in turn moves the second connecting rod, which in turn moves the sliding block. The sliding block moves the mounting plate, which in turn moves the rubber scraper. The rubber scraper wipes the window, achieving automatic window cleaning. Different widths of rubber scrapers can be installed to clean windows of varying widths. A tension spring automatically adjusts the position of the mounting plate, ensuring the rubber scraper remains firmly in contact with the window glass. The design enhances the cleaning effect on the glass and broadens the applicability of the device. The baffle prevents the slider from deviating from its path, and the push button allows the motor to automatically switch between forward and reverse rotation. When the length of the window glass is inconsistent, only guide rails of different lengths need to be customized without changing the motor control, making the device more convenient to use. The mounting plate can be rotated from the left to the right to wipe the glass on the right side, making the device more applicable, more complete, and more in line with market demands. The cam rotation drives the push block to move up and down, the push block drives the piston rod to move up and down, and the piston rod drives the piston block to move up and down. Due to the action of the one-way valve, water is drawn from the inlet pipe into the water tank, and then from the water tank through the outlet pipe into the spray tank, and sprayed out from the nozzle to clean the window.
