Description

Technical Field

[0001] This utility model belongs to the field of cleaning tools technology, and in particular relates to a window scraper. Background Technology

[0002] Chinese patent CN210158541U discloses a "Water-Retaining Window Scraper," in which a flexible scraper blade is fixed to a scraper blade holder, and a water-retaining base is detachably installed below the scraper blade holder. When the water-retaining base is installed on the scraper blade holder, a water-retaining cavity is formed between the water-retaining base and the scraper blade holder. The water-retaining cavity has an opening, and the flexible scraper blade covers the opening. When the flexible scraper blade is pushed upwards, liquid can enter the water-retaining cavity through the opening under the guidance of the flexible scraper blade. Its structure is relatively complex, and it only has a scraping function without a cleaning function, resulting in a relatively limited usage. Furthermore, the water retention after scraping is achieved by the water-retaining base, and the water-retaining base and the scraper blade holder are detachably connected, increasing the overall structural complexity.

[0003] Chinese patent CN204971098U discloses a "Water-Saving Window Scraper," which includes a water storage device comprising a water tank and a collection trough extending from the outside of the water tank. A cleaning cloth is placed on the upper surface of the cleaning head. It utilizes the collection trough to collect wastewater and the scraper and cleaning cloth to perform the cleaning function. The scraper and collection trough are separate structures with independently installed water tanks, resulting in a relatively complex structure and low ease of use. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a window scraper that can directly absorb the liquid scraped by the scraper with the cleaning brush head, avoiding the liquid from flowing everywhere and achieving a high degree of cleanliness.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a window scraper, including: an adapter, a main body connected to the adapter, and a scraper and a cleaning brush head disposed on opposite sides of the main body. The cleaning brush head covers one side of the main body, and at least a portion of the cleaning brush head is in contact with the surface of the main body and extends to the other side where the scraper is located, so that the cleaning brush head is close to or in contact with the scraper to absorb the liquid scraped by the scraper.

[0006] In this invention, the liquid scraped by the scraper is absorbed by the cleaning brush head, preventing the liquid from flowing everywhere and thus avoiding dirty water from flowing onto the user's arm, ensuring the user's cleanliness; moreover, the liquid scraped by the scraper is directly absorbed by the cleaning brush head, which plays a certain role in liquid storage, eliminating the need for a separate water storage structure and simplifying the structure; the cleaning brush head's absorption of liquid also facilitates cleaning, eliminating the need to dip the brush head in liquid during cleaning.

[0007] Furthermore, the scraper is equipped with a flow guiding structure, which guides and transports the liquid scraped by the scraper to the surface of the main body. The flow guiding structure ensures that as much of the liquid scraped by the scraper as possible is delivered to the upper surface of the main body.

[0008] Furthermore, the flow-guiding structure is a hydrophilic material layer covering the lower surface of the scraper, or the flow-guiding structure is a capillary channel provided on the lower surface of the scraper. The hydrophilic material layer allows more of the liquid scraped by the scraper to flow downwards along the hydrophilic material layer, so that all the liquid scraped by the scraper is delivered to the upper surface of the main body, making it convenient for the cleaning brush head to absorb the liquid; the capillary channel allows the scraper to not only scrape off the liquid attached to windows, walls, etc., but also to collect the liquid, so that as much of the scraped liquid as possible is guided and delivered to the upper surface of the main body.

[0009] Furthermore, the main body is bent to form a liquid storage area, which is used to collect the liquid scraped by the scraper, and the cleaning brush head extends into this liquid storage area. The liquid storage area is formed by bending the main body, which is convenient to process and facilitates liquid collection.

[0010] Furthermore, liquid storage baffles are formed at both ends of the liquid storage area to prevent liquid from flowing out. The liquid storage baffles can prevent the liquid in the liquid storage area from flowing outward, so that the liquid storage area can play a better role in storage. At this time, the liquid storage area is equivalent to an open water storage cavity. Not only can the curved surface guide the liquid into the liquid storage area, but the liquid can also accumulate in the liquid storage area, greatly simplifying the overall structure.

[0011] Furthermore, the liquid storage area is an arc-shaped groove structure formed by bending the main body, with the opening of the arc-shaped groove facing away from the adapter. The bottom of the main body is the liquid storage area, and the liquid scraped by the scraper can quickly flow to the liquid storage area through the side of the arc surface. The liquid is temporarily collected in the liquid storage area, making it convenient for the cleaning brush head to extend into the liquid storage area to absorb the liquid.

[0012] Furthermore, the angle between the plane of the scraper and the horizontal plane at the bottom of the liquid storage area is 30-60°. With this setting, the liquid storage area can play a better role in liquid storage, the scraper is easier to use, and the liquid scraped by the scraper 3 can flow into the liquid storage area as quickly as possible.

[0013] Furthermore, the cleaning brush head covers the inner and outer surfaces and side surfaces of one side of the main body along its entire length, and the end of the cleaning brush head adheres to the surface of the main body along its entire length and extends close to the end of the scraper. The entire end of the cleaning brush head absorbs liquid in the liquid storage area, resulting in high absorption efficiency. This facilitates the rapid and concentrated absorption of liquid scraped by the scraper, preventing liquid from flowing everywhere.

[0014] Furthermore, the main body is provided with a blocking protrusion along its length, located at the end of the scraper, and forming a through hole for liquid flow. The blocking protrusion can prevent impurities contained in the liquid scraped by the scraper from flowing into the cleaning brush head, and also provides good reinforcement, increasing the overall strength of the main body.

[0015] Furthermore, the main body has mounting portions at both ends, and the scraper is connected to a rotating component. This rotating component is rotatably connected to the mounting portion via a shaft. The liquid storage baffle is integrally connected to the mounting portion. The main body has multiple latching portions for rotatably connecting the shaft, and these latching portions are connected to blocking protrusions. The scraper's mounting structure is simple and stable, easy to assemble and disassemble, has high overall strength, and a long service life for the window scraper.

[0016] The beneficial effects of this utility model are: the liquid scraped by the scraper is absorbed by the cleaning brush head, preventing the liquid from flowing everywhere and thus preventing dirty water from flowing onto the user's arm, ensuring the user's cleanliness; moreover, the liquid scraped by the scraper is directly absorbed by the cleaning brush head, which plays a certain role in liquid storage, eliminating the need for a separate water storage structure and simplifying the structure; the cleaning brush head's absorption of liquid also facilitates cleaning, eliminating the need to dip it in liquid during cleaning; the flow guiding structure ensures that as much of the liquid scraped by the scraper as possible is delivered to the upper surface of the main body; the liquid storage area is formed by bending the main body, which is convenient to process and facilitates liquid collection.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0033] like Figure 1As shown, a window squeegee includes an adapter 1, a main body 2 connected to the top of the adapter 1, and a scraper 3 and a cleaning brush head 4 disposed on opposite sides of the main body 2. Taking the illustrated direction as an example, the left side of the main body 2 is the first side, and the right side is the second side. The cleaning brush head 4 covers the first side of the main body 2, and at least a portion of the cleaning brush head 4 adheres to the upper surface of the main body 2 and extends towards the second side where the scraper 3 is located. This allows the cleaning brush head 4 to approach or contact the scraper 3, facilitating the absorption of liquid scraped by the scraper 3. In this embodiment, the cleaning brush head 4 is a conventional cleaning cotton head, made of a flexible, absorbent material such as a sponge.

[0034] In this invention, the liquid scraped by the scraper 3 flows towards the lower part of the scraper or towards the main body and is absorbed by the cleaning brush head 4, preventing the liquid scraped by the scraper 3 from flowing everywhere, thus preventing dirty water from flowing onto the user's arm and ensuring the user's cleanliness; moreover, the liquid scraped by the scraper 3 is directly absorbed by the cleaning brush head 4, which plays a certain role in liquid storage, eliminating the need for a separate water storage structure and simplifying the structure; the cleaning brush head 4's absorption of liquid also facilitates cleaning, eliminating the need to dip it in liquid during cleaning.

[0035] A flow guiding structure 31 is provided on the lower surface of the scraper 3. The flow guiding structure 31 is used to guide and transport the liquid scraped by the scraper 3 to the upper surface of the main body 2. Specifically, the flow guiding structure 31 can first transport the liquid to the end of the scraper 3 and then to the upper surface of the main body 2, or the flow guiding structure 31 can directly transport the liquid to the upper surface of the main body 2. The ultimate goal is to transport as much of the liquid scraped by the scraper 3 as possible to the upper surface of the main body 2.

[0036] Specifically, such as Figure 10 , Figure 11 As shown, the flow guiding structure 31 can be a hydrophilic material layer 311 covering the lower surface of the scraper 3. Specifically, it is a PEG hydrophilic coating or a PU hydrophilic coating. It can cover the entire lower surface of the scraper 3 or only a portion of the lower surface of the scraper 3, with the portion near the scraping tip of the scraper 3 not covered by the hydrophilic material layer 311. Due to the presence of the hydrophilic material layer 311, more of the liquid scraped by the scraper 3 can flow downwards along the hydrophilic material layer 311, thereby ensuring that all the liquid scraped by the scraper 3 is delivered to the upper surface of the main body 2, facilitating the absorption of liquid by the cleaning brush head 4.

[0037] like Figure 8 , Figure 9As shown, the flow guiding structure 31 can also be a capillary flow guiding groove 312 provided on the lower surface of the scraper 3. Multiple capillary flow guiding grooves 312 are arranged in parallel on the lower surface of the scraper 3. Specifically, the capillary flow guiding groove 312 is formed by recessing from the lower surface of the scraper 3 inward. It extends from the position near the scraping tip of the scraper 3 to the end of the scraper 3. It uses the capillary effect to absorb the liquid scraped by the scraper 3 and guide it to the end of the scraper 3, thereby achieving the function of guiding and transporting the liquid to the upper surface of the main body 2, which facilitates the cleaning brush head 4 to absorb the liquid.

[0038] A flow guiding structure 31 is provided on the lower surface of the scraper 3, so that the scraper 3 in this utility model not only plays the role of scraping off the liquid attached to windows, walls and other surfaces, but also plays the role of collecting the liquid, so that the scraped liquid is guided and transported to the upper surface of the main body 2 as much as possible.

[0039] The specific shape of the main body 2 is not limited in the above structure. It can be planar, curved, or composed of multiple bent surfaces, and there are no specific restrictions. In order to achieve a good liquid collection effect, the main body 2 is bent to form a liquid storage area 21. The liquid storage area 21 is used to collect the liquid scraped by the scraper 3. Its main function is to concentrate the liquid scraped by the scraper 3 to the liquid storage area 21 and facilitate the cleaning brush head 4 to absorb it.

[0040] The specific way the liquid storage area 21 is formed is not limited; it can be a single arc bend, multiple arc bends, a single bend formed by bending a plane, or multiple bends formed by bending a plane. The end of the cleaning brush head 4 extends into the liquid storage area 21, thereby facilitating its rapid and maximum absorption of liquid.

[0041] like Figures 2-4 As shown, in this embodiment, the liquid storage area 21 is an arc-shaped groove structure formed by bending the main body 2. The opening of the arc-shaped groove is away from the adapter 1, that is, the main body 2 is a concave arc surface, so its inner bottom is the liquid storage area 21. The liquid scraped by the scraper 3 can flow quickly to the liquid storage area 21 through the side of the arc surface. The liquid is temporarily collected in the liquid storage area 21, which makes it convenient for part of the cleaning brush head 4 to extend into the liquid storage area 21 to absorb the liquid.

[0042] like Figures 5-7 As shown, to prevent the liquid in the storage area 21 from flowing outward from the end, and to better utilize the liquid storage function, at both ends of the storage area 21 (within the range shown), Figure 7 (Taking the direction shown as an example) A liquid storage baffle 22 is formed to prevent the liquid from flowing out. At this time, the liquid storage area 21 is equivalent to an open water storage cavity. Not only can the curved surface guide the liquid into the liquid storage area 21, but the liquid can also accumulate in the liquid storage area 21, which greatly simplifies the overall structure.

[0043] like Figure 7As shown, the angle α between the plane S1 where the scraper 3 is located and the horizontal plane S2 where the bottom of the liquid storage area 21 is located is 30-60°. At this time, the liquid storage area 21 can play a better role in liquid storage, and the scraper 3 is easier to use. The liquid scraped by the scraper 3 can also flow into the liquid storage area 21 as soon as possible.

[0044] In this embodiment, the cleaning brush head 4 covers the entire length of the first side of the main body 2, including its inner surface (upper surface in the figure), outer surface (lower surface in the figure), and side surface. This provides support for the cleaning brush head 4, allowing cleaning to be performed against walls, glass surfaces, etc., using the side of the main body 2 and the cleaning brush head 4. Furthermore, the entire length of the end of the cleaning brush head 4 is flush with or nearly flush with the upper surface of the main body 2, extending close to the end of the scraper 3. In other words, the entire end of the cleaning brush head 4 absorbs liquid in the liquid storage area 21.

[0045] like Figure 3 , Figure 6 As shown, the main body 2 is provided with a blocking protrusion 24 along its length. The blocking protrusion 24 is located at the end of the scraper 3, and multiple through holes 241 for liquid flow are formed on the blocking protrusion 24. The blocking protrusion 24 can prevent impurities contained in the liquid scraped by the scraper 3 from flowing to the cleaning brush head 4. At the same time, the blocking protrusion 24 plays a good reinforcing role and increases the overall strength of the main body 2.

[0046] like Figures 12-14 As shown, mounting portions 23 are provided at both the front and rear ends of the main body 2. The scraper 3 is made of an elastic material such as silicone and is snapped onto the rotating member 32. The rotating member 32 is rotatably connected to the mounting portion 23 via a shaft 33. The aforementioned liquid storage baffle 22 is integrally connected to the mounting portion 23, which also increases the structural strength of the mounting portion 23. Multiple snap-fit ​​portions 34 are provided along the length of the main body 2. The shaft 33 extends along the entire length of the rotating member 32, exposing portions of the shaft 33 in multiple areas. These exposed portions of the shaft 33 are rotatably connected to the snap-fit ​​portions 34, thereby achieving a stable assembly connection of the rotating member 32. To further increase the overall structural stability, the snap-fit ​​portions 34 are fixedly connected to the blocking protrusions 24.

[0047] When using this window scraper, the cleaning brush head 4 is first used to deeply clean the glass or wall surface. Then, the scraper blade 3 is used to scrape the liquid downwards against the glass or wall surface, effectively removing any remaining liquid. The liquid flows along the scraper blade 3 through the guide structure 31 and is transported to the upper surface of the main body 2, where it accumulates in the liquid storage area 21. At this time, the end of the cleaning brush head 4 directly extends into the liquid storage area 21 to absorb the liquid. The scraper blade 3 does not cause the liquid to flow everywhere when scraping the liquid, preventing dirty water from flowing onto the user's arm and ensuring the user's cleanliness. At the same time, after the cleaning brush head 4 has absorbed the liquid, it is not necessary to dip it in additional liquid when cleaning another area of ​​the glass or wall surface, achieving a good water-saving effect.

[0048] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
