Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a glass window cleaner. Background Technology

[0002] With the development of modern architecture, glass windows are widely used in various types of buildings, including residential buildings, commercial office buildings, and large shopping malls, leading to a growing demand for window cleaning. Window cleaners, specifically designed for cleaning glass surfaces, have emerged as a result. Their basic working principle typically involves using a scraper blade to contact the glass surface, and the movement of the blade removes dirt, dust, and water stains.

[0003] However, existing window washer systems have revealed numerous drawbacks in practical use. For example, their operational precision is severely lacking when moving across the window surface, making it difficult to accurately directionally move and clean according to the user's expectations. This is especially true when cleaning large or high-rise windows; the lack of effective directional control results in chaotic movement trajectories, leading to some areas being repeatedly cleaned while others are missed, significantly reducing cleaning effectiveness. This lack of directional control is particularly evident in large-area window cleaning scenarios, not only drastically reducing cleaning efficiency and consuming excessive manpower and time, but also potentially causing scratches and damage to the glass surface due to repeated cleaning, affecting the glass's appearance and lifespan. Furthermore, the residual dirt in missed areas fails to meet cleaning quality requirements.

[0004] In conclusion, the lack of directional control function in existing window cleaners severely restricts their application in cleaning large areas of windows. There is an urgent need for an innovative technology to solve this problem and improve the efficiency, quality, and convenience of window cleaning. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] Please see Figures 1 to 4 As shown, this utility model provides a glass window cleaner, including a protective cover 10, a water tank 11, a drive component 12, a universal rotating wheel 13, a support body, a water scraper 15, and a scraper blade 16. The protective cover 10 has an outer surface and an inner surface arranged opposite each other along the thickness direction. The protective cover 10 has a through hole penetrating the outer surface and the inner surface, and a receiving groove is provided on the inner surface. The water tank 11 has a through hole, and a water inlet 111 is provided in the area of ​​the water tank 11 exposed to the external space. The drive component 12 is disposed in the receiving groove. The universal rotating wheel 13 is connected to the drive component 12. The central shaft of the support body is driven by the universal rotating wheel 13, and the universal rotating wheel 13 drives the support body to rotate. The water scraper 15 is disposed on the support body. The scraper blade 16 is disposed on the water scraper 15. Among them, an electromagnetic coil (not shown in the figure) is disposed on the output shaft of the drive component 12, and a permanent magnet (not shown in the figure) is disposed on the universal rotating wheel 13.

[0035] This utility model uses an electromagnetic coil on the output shaft of the drive component 12 and a permanent magnet on the universal rotating wheel 13 to form a magnetic coupling transmission device. By precisely controlling the magnetic field direction of the electromagnetic coil, the rotation direction of the universal rotating wheel 13 is changed, so that the universal rotating wheel 13 can achieve precise orientation control, avoiding omissions or repeated cleaning, and greatly improving work efficiency and work quality.

[0036] Preferably, the drive component 12 can be a DC motor, with an electromagnetic coil mounted on the output shaft and a permanent magnet mounted on the universal rotating wheel 13. In this embodiment, by changing the magnitude and direction of the current in the electromagnetic coil, the strength and direction of the magnetic coupling can be flexibly controlled, thereby controlling the rotation speed and direction of the universal rotating wheel 13. This provides great flexibility to the operation of the washer. For example, when cleaning windows of different shapes and sizes, the moving speed and turning angle of the washer can be adjusted according to actual needs, allowing the scraper 16 to better adapt to the window surface, improving cleaning efficiency and quality. Moreover, the use of magnetic coupling between the electromagnetic coil and the permanent magnet for power transmission avoids the direct contact and wear of traditional mechanical transmission methods. This non-contact transmission can greatly extend the service life of transmission components and reduce failures and maintenance costs caused by wear. For example, under prolonged and frequent use of the window washer, mechanical transmission components such as gears or belts may experience wear and loosening, while magnetic coupling transmission does not have these problems.

[0037] In one embodiment, the support body includes multiple scraper blade frames 141 and a circular bracket 142, with the multiple scraper blade frames 141 arranged around the circular bracket 142. Preferably, the scraper blade frames 141 and the circular bracket 142 are made of plastic steel. The scraper blade frames 141 are designed as elongated structures, and the elongated scraper blade frames 141 and the circular bracket 142 can be welded together, achieving a very firm connection between the scraper blade frames 141 and the circular bracket 142, ensuring that no loosening occurs during long-term rotation and scraping operations. The aforementioned support body provides stable physical support for the water scraper frame 15 and the scraper blades 16, ensuring that the multiple water scraper frames 15 and the scraper blades 16 maintain a good relative position and posture during operation, which helps to maintain a stable and efficient cleaning effect.

[0038] In one embodiment, a first gear (not shown) is provided on the inner wall of the circular support 142, and a second gear (not shown) is provided on the outer wall of the universal rotating wheel 13. The first gear (not shown) and the second gear (not shown) mesh, and the gear meshing transmission method can provide stable and reliable power transmission. When the universal rotating wheel 13 rotates under the action of the drive component 12, the second gear on its outer wall drives the first gear on the inner wall of the circular support 142 to rotate, thereby smoothly transmitting power to the circular support 142, and then driving the support body and the water scraper 15 and scraper 16 on it to rotate. This transmission method avoids slippage or slippage during power transmission, ensuring that the scraper 16 of the cleaner can rotate at the expected speed and direction, ensuring the stability of the cleaning work. Because the gear transmission has high precision, it can respond quickly and accurately when the cleaner needs to change direction or adjust the rotation speed. For example, when the cleaner is cleaning a curved window or needs to avoid obstacles on the window, the drive component 12 controls the universal rotating wheel 13, and combined with the precision of the gear transmission, the scraper 16 can quickly adjust its position and rotation state to better adapt to various conditions on the window surface and achieve precise cleaning operation.

[0039] In one embodiment, there are multiple water squeegee frames 15, each mounted on the scraper blade 16 frame 141. Preferably, the water squeegee frames 15 are made of plastic and are elongated in shape. Multiple elongated water squeegee frames 15 are arranged around the center of the scraper blade 16, and each water squeegee frame 15 is arranged radially around the scraper blade 16. That is, multiple water squeegee frames 15 are arranged radially around the scraper blade 16, so that after the cleaning liquid is supplied from the water tank 11 or other supply sources, it can be evenly distributed to various parts of the scraper blade 16 and different areas of the window surface through each water squeegee frame 15. Regardless of whether the scraper blade 16 is rotating or translating, the entire area covered by the scraper blade 16 can be moistened with cleaning liquid, avoiding the problem of uneven distribution of cleaning liquid leading to poor cleaning effect in some areas, and achieving an all-round cleaning liquid coverage effect. Furthermore, multiple wiper brackets 15 are installed on the wiper blade 16 frame 141, providing multi-point support for the wiper blade 16 together with the wiper blade 16 frame 141. The wiper blade 16 is usually a component with a certain degree of elasticity. The coordinated support of the wiper brackets 15 and the wiper blade 16 frame 141 can ensure that the wiper blade 16 maintains the correct shape and posture during operation, so that it can better fit the window surface, maintain uniform and appropriate contact pressure, and avoid excessive local deformation of the wiper blade 16 due to single-point support, which would affect the wiping effect and the service life of the wiper blade 16.

[0040] As an extension, the window cleaner provided in this embodiment also includes a conduit (not shown in the figure). One end of the conduit is connected to a water tank 11, and the other end is connected to a squeegee 15. The squeegee 15 has a flow guiding structure along its length, and the liquid flowing out of the conduit is input to the scraper blade 16 through the flow guiding structure. As an example, a main flow channel 151 extending along its length can be provided on the squeegee 15, and several flow guiding branches 152 extending along its thickness can be provided on the squeegee 15. The liquid flowing out of the conduit first enters the main flow channel 151, then enters the flow guiding branches 152 and flows out, so that the liquid can be evenly distributed on the scraper blade 16. Thus, when the scraper blade 16 scrapes the window, each part can be assisted by an appropriate amount of cleaning liquid, so that the stains can be fully softened and dissolved. Whether it is dust, water stains, or oil stains, all kinds of stains can be more effectively removed by the scraper blade 16, greatly improving the quality and effect of cleaning.

[0041] Furthermore, the scraper blade 16 can be made of wear-resistant rubber, and its edges can be wavy or serrated, greatly increasing the contact area and friction between the scraper blade 16 and the stain. During the scraping process, these irregular edge shapes can better "grab" the stain, and compared to traditional smooth-edged scraper blades 16, they are more effective at removing stubborn stains (such as dried water stains, bird droppings, oil stains, etc. on glass). For example, when the wavy edge comes into contact with the stain, the crests and troughs can embed themselves into the stain from different angles, making it easier to peel the stain off the glass surface as the scraper blade 16 moves; the serrated edge is like a series of small "scrapers," enhancing the ability to cut and scrape away stains and improving cleaning efficiency.

[0042] This utility model uses a protective cover 10 to house the drive component 12 in the receiving groove, which effectively protects the drive component 12 from the influence of external environmental factors (such as dust, water splash, collision, etc.), reduces the risk of equipment damage, and improves the stability and service life of the equipment.

[0043] Based on the same inventive concept, this utility model also provides a window washer as described above, which further includes a safety rope (not shown in the figure). One end of the safety rope is connected to the window washer, and the other end is used for fixation. During window cleaning, especially when cleaning operations are carried out on high-rise buildings, there are many unsafe factors. In such cases, the safety rope can firmly hold the washer, preventing it from falling directly and avoiding serious injury and damage to people, vehicles, and other items below, thus ensuring the safety of the surrounding environment.

[0044] 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.
