Description

Technical Field

[0001] This utility model relates to the field of window cleaning device technology, and in particular to an automatic window cleaning device. Background Technology

[0002] In today's era of rapid economic development, skyscrapers are being built one after another, making window cleaning at high altitudes increasingly difficult. Most window cleaning still relies on manual labor, leading to the emergence of the "spider-man" window cleaning profession. However, working suspended dozens of stories high carries extremely high risks. Inadequate safety measures can not only seriously threaten lives but also damage buildings and surrounding facilities. While there are double-sided, magnetically attached window cleaners on the market, their adhesion is insufficient for very thick glass, making them prone to falling. For relatively thin glass, they can easily damage it and cannot reach certain hard-to-reach areas. Fully automatic window cleaning robots are expensive and not very user-friendly for those with limited budgets. Some window cleaner devices require user assembly and adjustment, posing a challenge for users unfamiliar with operation. Therefore, we propose an automatic window cleaner to solve these problems. Utility Model Content

[0003] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0004] Specifically, the technical problem to be solved by this utility model is to provide an automatic window cleaner to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An automatic window cleaner includes a first aluminum channel and a second aluminum channel. A water storage tank is installed at the top of the first and second aluminum channels. A water pipe is installed between the two sets of water storage tanks. Multiple nozzles are installed on the outer wall of the bottom end of the water pipe. A water pump is installed on the water storage tank. A DC geared motor is installed at the top of the first aluminum channel. A lead screw is rotatably connected inside the first aluminum channel, and the top end of the lead screw is connected to the output end of the DC geared motor. Silent copper-sleeved optical shafts are installed on both sides inside the first and second aluminum channels. Guide sliders are slidably connected to the outside of the silent copper-sleeved optical shafts. A threaded groove corresponding to the lead screw is provided in the middle of the guide slider in the first aluminum channel. An aluminum strip is connected between the two sets of guide sliders through an installation assembly. A cleaning cloth is glued to the outer wall of the aluminum strip. Limit switches are installed at both the upper and lower ends of the inner wall of the second aluminum channel.

[0007] As an improved technical solution, the mounting assembly includes mounting seats fixed to the outside of two sets of guide sliders. Each of the two sets of mounting seats has a positioning groove at one end opposite to the other. Each of the two sets of mounting seats has a rotating sleeve rotatably connected to its top. Each of the two sets of rotating sleeves has a retaining plate fixed to its outer wall. Each of the two outer walls of the aluminum strip has a protruding plate fixed to its two sides. Each of the two sets of protruding plates can be inserted into the positioning groove on the mounting seat.

[0008] As an improved technical solution, the input terminals of both the water pump and the DC geared motor are electrically connected to an external controller via wires.

[0009] As an improved technical solution, the water storage tank has an internal cavity filled with washing liquid.

[0010] As an improved technical solution, the wiping cloth on the aluminum strip is composed of multiple sets of ultra-fine cleaning squeegees.

[0011] As an improved technical solution, the width of the convex plate is the same as the width of the inner wall of the positioning groove on the mounting base.

[0012] As an improved technical solution, the outer wall of the bottom end of the card plate is in full contact with the top end of the convex plate.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This utility model features longitudinally movable aluminum strips installed on the outside of the first and second aluminum troughs, allowing the cleaning cloth on the strips to effectively clean the glass surface during movement. Combined with the nozzles installed at the top of the first and second aluminum troughs, the cleaning liquid in the water tank is sprayed onto the glass surface by the water pump, improving the cleaning effect. This device has low overall power consumption, low cost, and high efficiency, making it easy to promote and use, and is especially suitable for home use.

[0015] 2. This utility model has an installation base installed on the outside of the guide slider, and a rotatable rotating sleeve installed on the top of the installation base. When it is necessary to disassemble the aluminum strip, the locking plate on the outside of the rotating sleeve can be pulled, so that the rotating sleeve drives the locking plate to rotate away from the top of the positioning groove. This allows the locking plate to quickly release the limiting position on the protruding plate in the positioning groove, so that the aluminum strip can be lifted upward and the protruding plates on both sides of the aluminum strip can be completely removed from the positioning groove on the installation base. This facilitates the quick disassembly of the aluminum strip and the cleaning cloth on the aluminum strip can be cleaned and replaced. Attached Figure Description

[0026] Figures 1 to 4 As shown, this embodiment provides an automatic window cleaner, including a first aluminum channel 1 and a second aluminum channel 2. A water storage tank 3 is installed at the top of the first aluminum channel 1 and the second aluminum channel 2. The water storage tank 3 has an internal cavity filled with detergent. A water pump 6 compresses the contents of the water storage tank 3, causing the detergent to be sprayed from nozzles 5 onto the glass surface, softening the stains and facilitating subsequent cleaning. A water pipe 4 is installed between the two water storage tanks 3. Multiple nozzles 5 are installed on the outer wall of the bottom end of the water pipe 4. A water pump 6 is installed on the water storage tank 3. A nozzle 5 is installed at the top of the first aluminum channel 1. The DC geared motor 7 has a lead screw 8 rotatably connected inside the first aluminum channel 1. The top end of the lead screw 8 is connected to the output end of the DC geared motor 7. Silent copper sleeve optical shafts 10 are installed on both sides inside the first aluminum channel 1 and the second aluminum channel 2. Guide sliders 9 are slidably connected to the outside of the silent copper sleeve optical shafts 10. The guide sliders 9 in the first aluminum channel 1 have a threaded groove in the middle corresponding to the lead screw 8. The two sets of guide sliders 9 are connected by an aluminum strip 11 through an installation component. A wiping cloth 12 is glued to the outer wall of the aluminum strip 11. Limit switches 13 are installed at both the upper and lower ends of the inner wall of the second aluminum channel 2.

[0027] By installing longitudinally movable aluminum strips 11 on the outside of the first aluminum trough 1 and the second aluminum trough 2, the cleaning cloth 12 on the aluminum strips 11 can effectively clean the glass surface during movement. In addition, the nozzles 5 installed at the top of the first aluminum trough 1 and the second aluminum trough 2 can spray the cleaning liquid in the water tank 3 onto the glass surface under the action of the water pump 6, thereby improving the cleaning effect.

[0028] In other embodiments, the mounting assembly includes mounting bases 14 fixed to the outside of two sets of guide sliders 9. Each set of mounting bases 14 has a positioning groove 15 at one opposite end. Each set of mounting bases 14 has a rotating sleeve 17 rotatably connected to its top. Each set of rotating sleeves 17 has a retaining plate 18 fixed to its outer wall. Each set of aluminum strips 11 has a protruding plate 16 fixed to its outer walls on both sides. Both sets of protruding plates 16 can be inserted into the positioning grooves 15 on the mounting bases 14.

[0029] By installing a mounting base 14 on the outside of the guide slider 9, and installing a rotatable rotating sleeve 17 on the top of the mounting base 14, when it is necessary to disassemble the aluminum strip 11, the locking plate 18 on the outside of the rotating sleeve 17 can be pulled, so that the rotating sleeve 17 drives the locking plate 18 to rotate away from the positioning groove 15. This allows the locking plate 18 to quickly release the restriction on the protruding plate 16 in the positioning groove 15, and the aluminum strip 11 can be lifted upward, so that the protruding plates 16 on both sides of the aluminum strip 11 completely leave the positioning groove 15 on the mounting base 14. This facilitates the quick disassembly of the aluminum strip 11 and the cleaning cloth 12 on the aluminum strip 11 can be cleaned and replaced.

[0030] In other embodiments, the input terminals of both the water pump 6 and the DC geared motor 7 are electrically connected to an external controller via wires.

[0031] This design allows an external controller to control the start and stop of the water pump 6 and the DC geared motor 7 in real time, ensuring that the water pump 6 and the DC geared motor 7 can operate normally.

[0032] like Figure 2 As shown, the cleaning cloth 12 on the aluminum strip 11 is composed of multiple sets of ultra-fine cleaning squeegees. When the aluminum strip 11 moves longitudinally, the multiple sets of ultra-fine cleaning squeegees can move along the glass surface, which improves the cleaning effect of the cleaning cloth 12.

[0033] like Figure 4 As shown, the width of the protruding plate 16 is the same as the width of the inner wall of the positioning groove 15 on the mounting base 14;

[0034] With this design, when the aluminum strip 11 drives the protruding plate 16 to insert into the positioning groove 15 on the mounting base 14, it can effectively prevent the protruding plate 16 from shaking inside the positioning groove 15, thus effectively improving the stability of the aluminum strip 11 during use.

[0035] like Figure 1 As shown, the bottom outer wall of the card plate 18 is in full contact with the top of the protruding plate 16;

[0036] With this design, when the card plate 18 rotates to the top of the positioning groove 15, the bottom of the card plate 18 can contact the top of the protrusion 16, allowing the card plate 18 to limit the upward movement of the protrusion 16 in the positioning groove 15.

[0037] This utility model provides an automatic window cleaner, the specific working principle of which is as follows:

[0038] In use, first drive the water pump 6 to pressurize the washing liquid in the water tank 3, allowing the washing liquid to be sprayed onto the glass surface through the nozzle 5 on the water pipe 4. After spraying, drive the DC geared motor 7 to start working, causing the guide slider 9 in the first aluminum groove 1 to slide along the silent copper sleeve optical axis 10 under the action of the thread. This allows the guide slider 9 to drive the aluminum strip 11 to move longitudinally, and the cleaning cloth 12 on the aluminum strip 11 to move longitudinally on the glass to clean the glass surface. When the second aluminum groove 2... When the inner guide slider 9 touches the limit switches 13 at both ends of the silent copper sleeve optical shaft 10, the limit switches 13 send a signal to control the DC geared motor 7 to run in reverse, so that the outer guide slider 9 of the silent copper sleeve optical shaft 10 moves in reverse along the silent copper sleeve optical shaft 10, so that the silent copper sleeve optical shaft 10 can drive the cleaning cloth 12 to move in reverse. When the silent copper sleeve optical shaft 10 touches another limit switch 13, it continues to move in reverse. This cycle repeats, so that the cleaning cloth 12 can thoroughly clean the glass surface.

[0039] All electrical components mentioned in this article are conventional and known devices.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
