Description

Technical Field

[0001] The present application belongs to the field of household cleaning tools, and in particular to a cleaning head of a scraping tool. Background Art

[0002] Brooms are a common cleaning tool in household life, generally used to clean surfaces such as floors and walls. Existing broom designs mostly have densely distributed bristles at the bottom of a long handle to clean debris and other debris on the floor. However, they are powerless against fine particles such as dust or liquid dirt such as water stains and oil stains. Therefore, there are scrapers on the market for scraping off such substances. However, such scrapers usually re-clean the floor that has been swept with a broom, so the same area needs to be cleaned twice, which is time-consuming and labor-intensive. In addition, because liquid dirt such as water stains and oil stains adhere more strongly to surfaces such as the floor than general dust and debris, scrapers on the market are generally thicker to improve their deformation ability and enhance the decontamination effect. However, the thicker size limits their ability to clean gaps and other locations on the floor.

[0003] Therefore, it is necessary to provide a cleaning head for a cleaning tool that is labor-saving to operate and can meet different cleaning requirements. Utility Model Content

[0004] This application aims to solve the problems of time-consuming and labor-intensive cleaning tools and incomplete cleaning in the prior art to a certain extent, and to provide a cleaning tool that has a thorough cleaning effect in a single cleaning and has a variety of cleaning methods. To this end, this application provides a cleaning head, including:

[0005] The plate body has a connector at the upper end for connecting to the handle;

[0006] The first cleaning portion includes a plurality of comb teeth arranged along the length direction of the plate body and extending downward from the lower end of the plate body, and is used to clean the surface to be cleaned;

[0007] a second cleaning portion formed as a strip-shaped body provided side by side with the first cleaning portion at the lower end of the plate body, so that when the first cleaning portion is used to clean the surface to be cleaned along a first side of the plate body, the second cleaning portion is located behind the first cleaning portion to scrape the surface to be cleaned at the same time;

[0008] The scraper has a deformation capability weaker than that of the second cleaning portion and extends toward a second side of the plate body that is opposite to the first side of the plate body.

[0009] In some embodiments, the length of the first cleaning portion extending from the plate body is less than the length of the second cleaning portion extending from the plate body, so that when the plate body is tilted toward the surface to be cleaned along the first side direction, the first cleaning portion and the second cleaning portion contact the surface to be cleaned at the same time.

[0010] In some embodiments, along the first side direction, the comb teeth include at least two rows, and the lengths of the comb teeth gradually become shorter.

[0011] In some embodiments, the angle between the scraper and the second cleaning portion does not exceed 90 degrees.

[0012] In some embodiments, the scraper and the second cleaning portion are both made of rubber, and the thickness of the scraper is greater than the thickness of the second cleaning portion, so that the scraper has a weaker deformation ability than the second cleaning portion.

[0013] In some embodiments, the scraper has a material hardness greater than that of the second cleaning portion, so that the scraper has a deformation capability weaker than that of the second cleaning portion.

[0014] In some embodiments, the lower end of the scraper has an edge extending along the length direction of the plate body.

[0015] In some embodiments, the width of the second cleaning portion along the first side direction gradually narrows from top to bottom.

[0016] In some embodiments, the first cleaning portion, the second cleaning portion, and the scraper are integrally formed.

[0017] In some embodiments, the plate body includes a clamping portion and a main body portion whose upper end is clamped in the clamping portion, and the first cleaning portion, the second cleaning portion, and the scraper are all connected to the lower end of the main body portion.

[0018] The cleaning head of the present application, on the one hand, by providing a strip-shaped second cleaning part at the rear end of the first cleaning part composed of a plurality of comb teeth, when cleaning the surface to be cleaned, the second cleaning part can clean up the dust and other fine particles missed in the tooth gaps of the first cleaning part. The two form a good complement to avoid the need to use a scraper to scrape dust and other operations in the area cleaned by the broom in the existing design, saving time and effort; on the other hand, by providing a scraper with a weaker deformation ability than the second cleaning part, in an environment with water stains, oil stains, etc., only the scraper can be used to clean such highly sticky stains, thereby improving the applicability of the cleaning head; in addition, by providing the scraper with a stronger deformation ability than the second cleaning part, especially when the scraper and the second cleaning part are made of the same material, by providing the second cleaning part with a thickness smaller than the scraper, the second cleaning part can be more easily extended into the gaps of the floor, wall, etc. relative to the scraper to clean the dust and other fine particles that cannot be thoroughly cleaned by the first cleaning part, thereby forming a cleaning head that is labor-saving to operate and adaptable to a wide range of environments.

[0033] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0034] This application discloses a cleaning head, which is generally used to clean relatively flat surfaces such as floors, walls, desks, and window glass, especially for cleaning surfaces such as floors that are relatively flat overall but inevitably have a small amount of gaps, depressions, or protrusions. Figure 1As shown, the cleaning head of the present application mainly comprises a plate body 1. The plate body 1 is generally flat and is generally made of plastic, rubber, metal, or other materials, or different parts of the plate body composed of these materials. The plate body 1 is generally provided with a hollow shape to reduce its weight. The portion outside the hollow portion remains generally flat, and its thickness may vary slightly in some places. A connector is provided at the upper end of the plate body 1 for connecting to the handle. The connector can be integrally formed with the handle to reduce processing costs, or it can be detachably connected by means of a snap-fit ​​structure or tight fit to facilitate component replacement. There are many ways to connect the handle to the cleaning head in existing designs, which will not be detailed here.

[0035] like Figure 1 As shown, the cleaning head of the present application also includes a first cleaning part 2, which is formed in a comb shape and consists of a plurality of comb teeth 21 extending downward from the lower end of the plate body 1 and arranged along the length direction of the plate body 1. The comb teeth 21 can be bristles or bristle clusters. For example, when the comb teeth 21 are made of PET, PP, PP, nylon, animal hair, synthetic fiber or other materials or a mixture thereof, the bristles are thinner, and each comb tooth 21 can be a bristle cluster composed of multiple bristles; when the comb teeth 21 are made of rubber, plastic or other materials, in order to reduce the difficulty of processing, each comb tooth 21 can be a single rubber tooth or plastic tooth, etc., of course, it can also be a combination of the above schemes. In addition, in the present application, the upper end and the lower end of the plate body 1 refer to the side of the plate body 1 connected to the first cleaning part 2 when the plate surface of the plate body 1 is perpendicular to the surface to be cleaned, that is, its largest relative side is perpendicular to the surface to be cleaned, so that the first cleaning part 2 can contact the first cleaning part 2, and the side opposite to the first cleaning part 2 is the upper end. Taking the surface to be cleaned as the ground as an example, when the plate surface of the plate body 1 is a plane perpendicular to the ground, the first cleaning part 2 is located at the lower end of the plate body 1 in the vertical direction, and the connecting head is located at the upper end in the vertical direction. At this time, on the plane of the plate body 1, the direction parallel to the ground is the length direction of the plate body 1, which is also the layout direction of the plurality of comb teeth 21. Generally, in the length direction of the plate body 1, the size of the plate body 1 is larger, so that the first cleaning part 2 has a longer cleaning range, thereby improving the cleaning efficiency. In the vertical direction, the size of the plate body 1 is relatively small to avoid increasing the volume of the cleaning head.

[0036] The cleaning head of the present application also includes a second cleaning part 3 and a scraper 4 extending to a second side opposite to the first side, wherein the second cleaning part 3 is formed into a strip-shaped body, that is, a scraping strip. The scraping strip can be a continuous long strip or a combination of multiple sheet scrapers. Regardless of the shape, it forms a basically continuous strip-shaped body along the length direction of the plate body 1, and the lowermost side is relatively flat, or it can be adaptively changed according to the unevenness of the ground. For example, the scraping strip is set in a form that is easy to elastically deform in the vertical direction, so that it can cross the obstacle while maintaining overall contact with the surface to be cleaned when encountering an obstacle on the surface to be cleaned, or it can extend into the ground gap when there is a gap in the ground to clean up small solid debris missed by the first cleaning part 2. Here, the two largest opposing faces of the plate body 1 are defined as its side faces, and the directions perpendicular to the two side faces are respectively the first side face and the second side face. When the cleaning head cleans along the first side face, the second cleaning portion 3 is located behind the first cleaning portion 2, that is, when the comb teeth 21 of the first cleaning portion 2 sweep across the surface to be cleaned, the second cleaning portion 3 maintains contact with the surface to be cleaned, so as to simultaneously perform a scraping operation on the surface to be cleaned. The scraper 4 is similar to the second cleaning portion 3, but its deformation ability is poor, that is, when encountering obstacles or gaps on the surface to be cleaned, its adaptability is poor. Taking a raised obstacle on the ground as an example, when the scraper 4 is scraping dirt on the ground (generally liquid dirt such as water stains and oil stains), at the location of the raised obstacle on the ground, due to the poor overall deformation ability of the scraper 4, the raised obstacle will lift the scraper 4, causing all parts of the scraper 4 except the position in contact with the raised obstacle to be lifted off the ground. Although the scraper 4 has poor adaptability to uneven ground, its better shape retention ability allows it to scrape off liquid dirt more easily on a flat ground, especially in environments such as glass surfaces, where it is easier to scrape off water stains on the glass surface. Therefore, the scraper 4 has a significantly better adaptability to the environment.

[0037] Therefore, the cleaning head of the present application can not only complete the basic cleaning operation through the combined action of the first cleaning part 2 and the second cleaning part 3, so that the second cleaning part 3 can supplement the cleaning of the debris missed between the tooth gaps of the first cleaning part 2 to achieve a better cleaning effect, but also can adapt to the gaps, protrusions, etc. on the surface to be cleaned through the second cleaning part 3 to ensure the cleaning effect on the uneven parts of the surface to be cleaned; it can also scrape off the liquid dirt with strong adhesion on the surface to be cleaned by using only the scraper 4, thereby achieving a better cleaning effect and adapting to a variety of environments to be cleaned through one cleaning head.

[0038] Furthermore, if Figure 2 、 3As shown, in the cleaning head of the present application, the length of the first cleaning part 2 extending from the plate body 1 is shorter than the length of the second cleaning part 3 extending from the plate body 1. Since the first cleaning part 2 and the second cleaning part 3 both extend from the lower end of the plate body 1 and are arranged side by side, the first cleaning part 2 and the second cleaning part 3 are roughly parallel. When in use, the user generally tilts the cleaning head and then moves the cleaning head from far to near to perform cleaning operations within a certain distance range. Therefore, in order to ensure that the first cleaning part 2 and the second cleaning part 3 can contact the surface to be cleaned at the same time, and to avoid the comb teeth 21 of the first cleaning part 2 from being excessively squeezed and deformed or interfering with the position of the second cleaning part 3 when the cleaning head is tilted, the length of the first cleaning part 2 extending from the plate body 1 is limited to be shorter than the length of the second cleaning part 3 extending from the plate body 1.

[0039] Furthermore, if Figure 2 、 3 As shown, the comb teeth 21 on the first cleaning part 2 include at least two rows, as described above, and the length of the comb teeth 21 gradually shortens along the first side. Similar to the length relationship between the second cleaning part 3 and the first cleaning part 2, the comb teeth 21 on the first cleaning part 2 maintain a relationship of gradually shortening in length along the first side, so that when the cleaning head is tilted, each comb tooth 21 can contact the surface to be cleaned at the same time, and can also avoid the comb teeth 21 in the front row from being excessively squeezed and deformed when the comb teeth 21 in the back row contact the surface to be cleaned along the first side, resulting in poor cleaning effect. Of course, the comb teeth 21 here refer to a cluster of bristles composed of a single bristle or multiple bristles, which are arranged in an overall manner so that the first cleaning part 2 has the effect of at least two rows. Therefore, each row of bristles or bristle clusters does not have to strictly extend along the length direction of the plate body 1, that is, it only needs to be kept in a longer arrangement range in the length direction of the plate body 1.

[0040] In some embodiments, as Figure 1-3 As shown, the angle between the scraper 4 and the second cleaning portion 3 does not exceed 90 degrees. Since the second cleaning portion 3 and the first cleaning portion 2 both extend downward from the lower end of the plate body 1, the second cleaning portion 3 is roughly parallel to the plate surface of the plate body 1, and the angle between the scraper 4 and the second cleaning portion 3 does not exceed 90 degrees. That is, when the plate surface of the plate body 1 is perpendicular to the surface to be cleaned, the scraper 4 also extends obliquely downward from the second side of the plate body 1, so that when the cleaning head is tilted toward the second side, as shown in FIG. Figure 3 As shown, the scraper 4 just contacts the surface to be cleaned. At this time, the first cleaning part 2 and the second cleaning part 3 can be separated from the surface to be cleaned or the pressure on the surface to be cleaned is not too large, so only the scraper 4 is used for scraping and sweeping.

[0041] Specifically, the material of the scraper 4 and the material of the second cleaning part 3 are both rubber, and the thickness of the scraper 4 is greater than the thickness of the second cleaning part 3, so that the scraper 4 has a deformation capacity weaker than that of the second cleaning part 3, to adapt to its demand for scraping liquids with strong adhesion. At the same time, the better deformation capacity of the second cleaning part 3 can also make it easier to adapt to the cleaning needs of uneven floors. Of course, rubber is only exemplified as one of the most commonly used materials. Materials with similar material properties to rubber, such as silicone, latex, fluororubber, nylon, etc., can also be used. In addition, in order to make the scraper 4 have a deformation capacity weaker than that of the second cleaning part 3, the scraper 4 and the second cleaning part 3 can also be set to different materials, for example, the scraper 4 uses materials such as aluminum alloy or plastic, while the second cleaning part 3 uses rubber.

[0042] Furthermore, since the scraper 4 is mainly used to scrape off liquid dirt on the surface to be cleaned, the scraper 4 needs to maintain close contact with the surface to be cleaned to prevent liquid dirt from leaking from the gap between the surface to be cleaned and the scraper 4. Therefore, the scraper 4 and the surface to be cleaned need to maintain direct line contact, thereby reducing the gap between the scraper 4 and the surface to be cleaned. In the present application, the lower end of the scraper 4 is provided with an edge 41 extending along the length direction of the plate body 1, so that when the scraper 4 is used to scrape off liquid dirt on the surface to be cleaned, the scraper 4 forms a line contact with the surface to be cleaned through the edge 41 to ensure that the gap between the scraper 4 and the surface to be cleaned is as small as possible. In order to ensure that the scraper 4 does not produce large deformation during scraping, and to ensure that the scraper 4 still maintains close contact with the slightly uneven surface to be cleaned, the scraper 4 can be set to a combination of relatively soft soft rubber and relatively hard metal or hard plastic parts, that is, the main body of the scraper 4 is set to metal or hard plastic parts to ensure that it does not produce large deformation, and the lower end of the scraper 4 is set to relatively soft rubber or soft plastic and other materials, which covers or fits the lower end of the metal or hard plastic part of the scraper 4, and an edge 41 is set at the lower end of the scraper 4. When the edge 41 of the rubber or soft plastic encounters slight unevenness on the surface to be cleaned, it can be slightly deformed to maintain constant contact with the surface to be cleaned, thereby preventing liquid dirt from leaking.

[0043] In some embodiments, the width of the second cleaning portion 3 along the first lateral direction maintains a trend of gradually narrowing from top to bottom, that is, when the plate surface of the plate body 1 is perpendicular to the surface to be cleaned, the portion of the second cleaning portion 3 closer to the surface to be cleaned has a smaller size along the first lateral direction. Since the second cleaning portion 3 has a better deformation ability than the scraper 4, when encountering a raised obstacle on the surface to be cleaned, the second cleaning portion 3 can maintain the greatest possible fit with the raised obstacle, thereby reducing the gap between the second cleaning portion 3 and the surface to be cleaned caused by the raised obstacle lifting the second cleaning portion 3, and preventing fine dust and other particulate matter from leaking out of the gap between the second cleaning portion 3 and the surface to be cleaned and remaining near the raised obstacle, resulting in poor cleaning effect.

[0044] When the scraper 4 is made of rubber, the first cleaning portion 2 and the second cleaning portion 3 can also be made of rubber or other materials. The three can be formed in one piece, that is, the first ends of the scraper 4, the first cleaning portion 2, and the second cleaning portion 3 are connected as a whole, and the second ends extend in a direction away from the plate body 1, thereby reducing production costs. In this case, the first end of the three connected as a whole can also be formed in one piece with the plate body 1, further reducing production costs. Figure 4 As shown, the plate body 1 can also be set as a clamping portion 11 and a main body portion 12 connecting the scraper 4, the first cleaning portion 2, and the first end of the second cleaning portion 3. The clamping portion 11 can use metal or hard plastic material to form a clamping plate on both sides of the main body portion 12, so that the main body portion 12 and the clamping portion 11 form a detachable structure. When any of the first cleaning portion 2, the second cleaning portion 3, and the scraper 4 is damaged, the main body portion 12 can be removed from the clamping portion 11 to replace it, thereby reducing the wear cost during use.
