Description
Technical Field
[0001] This utility model relates to the field of window scraper technology, and in particular to a window scraper with an adjustable head angle. Background Technology
[0002] A window scraper is a tool used for cleaning glass surfaces. The head of the window scraper has a wiping mop and a scraper on both sides. The wiping mop is wetted and comes into contact with the glass to wipe it, while the scraper removes water stains from the glass surface.
[0003] Existing window squeegees have an integrated mop head design. To cover a large area, the overall width of the integrated window squeegee is usually 350-450mm. However, the inner diameter of a typical household sink is only 250-300mm. The integrated window squeegee cannot be completely placed inside the sink. During cleaning, it can only wipe the edges of the mop head locally, and it is difficult to reach the stains in the middle. If not cleaned properly, it will leave marks on the glass. Summary of the Invention
[0004] This invention provides a window scraper with an adjustable head angle. The window cleaning kit can be detached separately and can be rubbed and washed in a sink. This avoids the problem of existing window scrapers having an integrated wiping mop head, which is too wide and makes it difficult to put the window scraper and wiping mop head into the sink for washing, resulting in incomplete cleaning and leaving marks on the glass.
[0005] This utility model provides a window wiper with an adjustable head angle, specifically including a window cleaning kit, a window cleaning head frame, and an extension rod. The window cleaning kit is fitted onto one side of the window cleaning head frame, and an extension rod is provided at the tail of the window cleaning head frame. The window cleaning kit has a pocket-shaped structure, and outer fiber columns are arranged in a spaced array on the outer side of the window cleaning kit. Both the outer fiber columns and the window cleaning kit are made of polyester-nylon composite fiber material, which has good water absorption performance. Velcro fastening strips are sewn and fixedly connected to both sides of the opening of the window cleaning kit.
[0006] Furthermore, both sides of the window cleaning head frame are integrally injection molded with rectangular frame scraper and window cleaning frame. The scraper is fixed to the inside of the scraper frame by a buckle for scraping off residual water stains. The middle part of the window cleaning head frame is integrally injection molded with a front connecting frame. The tail end of the front connecting frame is axially slidably connected to a limit post. The tail end of the front connecting frame and the head end of the rear connecting frame are rotatably connected.
[0007] Furthermore, the limiting post has side limiting protrusions on both sides, and the inner side of the rear connecting frame has an inner limiting groove in a circular array. The rear connecting frame is slidably connected to a rear handle and limited by a buckle. When the limiting post is pressed by hand, the limiting post moves toward the front connecting frame and compresses the support spring. The side limiting protrusions of the limiting post move and separate synchronously with the inner limiting groove. The limiting post and the front connecting frame are released, and the front connecting frame and the rear connecting frame can rotate to adjust the angle.
[0008] Furthermore, the window cleaning kit wraps around the window cleaning frame by attaching opposing Velcro fasteners. The window cleaning kit and Velcro fasteners are wrapped around the outside of the window cleaning frame. The window cleaning kit and the outer fiber column are attached to the door and window for wiping operations. The window cleaning kit can be rubbed and washed in a washbasin, achieving full-area soaking and rubbing cleaning of the window cleaning kit.
[0009] Furthermore, a support spring is fixedly connected between the limiting post and the front connecting frame. The support spring is a stainless steel compression spring. The support spring supports the limiting post to move upward. The limiting post and the rear connecting frame are slidably connected. The side limiting protrusion of the limiting post and the inner limiting groove are slidably connected.
[0010] Furthermore, the tail end of the extension rod is fixedly connected to the tail threaded tube, and the tail threaded tube is threadedly connected to the head end of the rear grip rod, allowing personnel to hold the rear grip rod to perform window cleaning operations at a more distant location.
[0011] Furthermore, the extension rod's head end and the rear handle's tail end are threadedly connected, allowing for window cleaning operations by holding the rear handle at close range. The extension rod can be connected to another extension rod via a tail threaded pipe thread, enabling the two extension rods to be connected in series, further increasing the length and extending the working range.
[0012] This utility model provides a window scraper with an adjustable head angle, which has the following beneficial effects: The window cleaning kit can be detached from the window cleaning head. The window cleaning kit can be removed separately and used for washing in the sink. This avoids the problem of existing window squeegees having an integrated cleaning head. Window squeegees are wider, making it difficult to put the window squeegee and cleaning head into the sink for washing, resulting in difficult cleaning and leaving marks on the glass if not cleaned properly.
[0013] The window cleaning head unit rotates with the front connecting frame to adjust the angle between the window cleaning head unit and the rear handle. After the window cleaning head unit and the rear handle are rotated to a right angle, it can be used to clean the large glass pane in the middle of the window. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a window wiper with an adjustable head angle, including a window cleaning kit 1, a window cleaning head frame 2, and an extension rod 3. The window cleaning kit 1 has a pocket-shaped structure, and outer fiber columns 101 are arranged in a spaced array on the outer side of the window cleaning kit 1. Both the outer fiber columns 101 and the window cleaning kit 1 are made of polyester-nylon composite fiber, which has good water absorption performance. Velcro fasteners 102 are sewn and fixedly connected to both sides of the opening of the window cleaning kit 1. The window cleaning kit 1 is fitted onto one side of the window cleaning head frame 2. Both sides of the window cleaning head frame 2 are integrally injection molded with rectangular frame scraper frame 201 and window cleaning frame 202. The inner side of the scraper frame 201 is secured by a clip. A scraper strip is fixed in place to remove residual water stains. The window cleaning head 2 has a front connecting frame 203 integrally injection molded in the middle. A limit post 204 is axially slidably connected to the tail end of the front connecting frame 203. The center of the limit post 204 and the rotating connection point between the front connecting frame 203 and the rear connecting frame 206 is aligned. The tail end of the front connecting frame 203 and the head end of the rear connecting frame 206 are rotatably connected. Side limiting protrusions 205 are provided on both sides of the limit post 204. An inner limiting groove 207 is formed in a circular array on the inner side of the rear connecting frame 206. A rear handle 209 is slidably connected to the tail end of the rear connecting frame 206 and is limited by a buckle. When the limiting post 204 is pressed, it moves towards the front connecting frame 203 and compresses the support spring 208. Simultaneously, the side limiting protrusion 205 of the limiting post 204 and the inner limiting groove 207 move and separate, releasing the limiting position of the limiting post 204 and the front connecting frame 203. The front connecting frame 203 and the rear connecting frame 206 can then rotate to adjust their angle. A support spring 208, a stainless steel compression spring, is fixedly connected between the limiting post 204 and the front connecting frame 203. The support spring 208 supports the limiting post 204 as it moves upward, and the limiting post 204 and the rear connecting frame 206 slide together. The side limiting protrusion 205 of the limiting post 204 and the inner limiting groove 207 are slidably connected. The end of the window cleaning head 2 is provided with an extension rod 3. The end of the extension rod 3 is fixedly connected to the tail threaded tube 302. The tail threaded tube 302 is threadedly connected to the head of the rear handle 301. The operator holds the rear handle 301 to perform window cleaning operations at a more distant position. The head of the extension rod 3 is threadedly connected to the tail of the rear handle 209. The operator can also hold the rear handle 209 to perform window cleaning operations at a closer distance. The extension rod 3 is threadedly connected to another extension rod 3 through the tail threaded tube 302 to realize the series connection of the two extension rods 3, further increasing the length and extending the working range.
[0019] In this embodiment, the window cleaning kit 1 wraps around the window cleaning frame 202 by attaching the opposing Velcro fasteners 102. The window cleaning kit 1 and the Velcro fasteners 102 surround the outside of the window cleaning frame 202. The window cleaning kit 1 and the outer fiber column 101 are attached to the door and window for wiping operations. The window cleaning kit 1 can be rubbed and washed in the sink, realizing full-area soaking and rubbing cleaning of the window cleaning kit 1. This avoids the situation where only the edges of the mop head can be wiped locally during cleaning, and the stains in the middle cannot be reached. Incomplete cleaning will leave strip-shaped or dot-shaped marks on the glass.
[0020] In this second embodiment, based on the first embodiment, inclined structures are provided on both sides of the upper part of the side limiting protrusion 205. This allows the inclined surfaces of the side limiting protrusion 205 to guide the circumferential rotation of the side limiting protrusion 205 while simultaneously moving axially. When the rotational force of the window cleaning head 2, the front connecting rotating frame 203, and the side limiting protrusion 205 is greater than that of the support spring 208, the inclined surfaces of the side limiting protrusion 205 rotate circumferentially along the inner limiting groove 207 while simultaneously moving axially, thereby automatically releasing the limit and rotating. This allows operation without pressing the limiting post 204.
[0021] The working principle of this embodiment: The window cleaning kit 1 is separated from the window cleaning frame 202 by the Velcro fastening strips 102 on both sides of the opening. The window cleaning kit 1 can be folded and rubbed separately. The window cleaning kit 1 is fully adaptable to the space of mainstream washbasins, allowing for rubbing and cleaning within the washbasin. This achieves full-area soaking and rubbing cleaning of the window cleaning kit 1, increasing the cleaning coverage to 100%. This solves the problem that integrated window scrapers, for large-area cleaning, typically have an overall width of 350-450mm, while the inner diameter of commonly used household washbasins is only 250-300mm. 00mm, the tool cannot be fully placed in the basin, and can only wipe the edge of the mop head during cleaning. The central stains cannot be reached. If not cleaned properly, it will leave streaks and dots on the glass. Improve window cleaning efficiency and surface cleanliness; Window cleaning kit 1 can be directly hand-rubbed in the basin. It has a high degree of stain removal between fibers. After cleaning, the moisture content of the kit can be controlled to within 30% by wringing it dry to avoid residual moisture and mold growth. It avoids the problem of the integrated tool being restricted by the frame and only able to be rinsed with water. It cannot rub, which makes it easy for stubborn stains to remain in the gaps between the fibers of the mop head and cause mold. By pressing the limiting post 204 with your hand, the limiting post 204 moves towards the front connecting frame 203 and compresses the support spring 208. The side limiting protrusion 205 of the limiting post 204 moves and separates from the inner limiting groove 207. The limiting post 204 and the front connecting frame 203 are released from their limits. The front connecting frame 203 and the rear connecting frame 206 can rotate to adjust the angle. When you release the limiting post 204, the support spring 208 supports the side limiting protrusion 205 of the limiting post 204 to move and the inner limiting groove 207 to slide in, thus achieving angle limiting operation. When adjusted to a 90° right angle, you can use the window cleaning head 2 and window cleaning kit 1 to perform horizontal window cleaning operation by holding the rear grip 301. The person wipes the glass in the middle of the window from the outside at the open window sash, expanding the cleaning range.
