Description
TECHNICAL FIELD
[0001] The present application belongs to the field of household cleaning tools, and in particular relates to a cleaning head of a scraping tool. BACKGROUND
[0002] In daily life, general floor, window, desktop cleaning, especially when it involves liquid stains such as water stains, oil stains or small particle stains on the surface to be cleaned, often requires the use of a scraper for scraping operation. The scraper in the existing design is usually a plate-shaped whole, with a straight cleaning edge at the lower end. During use, the cleaning edge is tightly attached to the surface to be cleaned, and then the scraper is moved in a direction perpendicular to the plate surface, thereby scraping off the dirt on the surface to be cleaned. The scraper of this structure has a large overall hardness, so it generally has good scraping effect. However, since the liquid stains on the surface to be cleaned in the general home environment are usually water, oil and the like accidentally spilled, and the small particle stains are usually dust, which will not be completely adhered to the surface to be cleaned, so the scraper only needs to maintain a certain integrity, that is, it can be scraped off. However, when the surface to be cleaned is uneven, such as a raised floor or slightly deformed glass, the existing design of the scraper will form a gap when scraping the uneven surface, thereby causing the dirt to be missed on the uneven surface, resulting in incomplete scraping.
[0003] Therefore, it is necessary to provide a cleaning head that can meet the scraping requirements and adapt to uneven surfaces to be cleaned, so as to achieve better cleaning effect. CONTENT OF THE INVENTION
[0004] The present application aims to solve the problem of incomplete scraping of the existing scraper on uneven surfaces to be cleaned to some extent, so as to provide a cleaning head of a cleaning tool with good scraping effect. To this end, the present application provides a cleaning head, comprising:
[0005] a plate-shaped main body portion, a plurality of slits are provided at the lower end of the main body portion, and the lower end of the main body portion is divided into a plurality of elastic scraping pieces;
[0006] the projections of the adjacent two elastic scraping pieces on the reference surface are continuous, so that when the cleaning head is used to scrape off liquid on the surface to be cleaned, the lower end of the main body portion is shaped as a continuous scraper;
[0007] wherein the reference surface is a plane parallel to the plate surface of the plate-shaped body of the main body portion.
[0008] In some embodiments, the projections of the adjacent two elastic scraping pieces at the slits on the reference surface partially overlap.
[0009] In some embodiments, the slit is shaped as a groove at the lower end of the main body, and the groove extends at an angle of no more than 90 degrees with the reference surface.
[0010] In some embodiments, the slit is shaped as a corrugated groove at the lower end of the main body.
[0011] In some embodiments, the width of the slit is 0-2mm.
[0012] In some embodiments, along the direction of the arrangement of the elastic blades, the overlapping width of the projections of the two adjacent elastic blades on the reference surface is no more than 3mm.
[0013] In some embodiments, the slit extends in a direction perpendicular to the reference surface, and the elastic blades on both sides of the slit remain adhered under no external force, so that the projections of the adjacent elastic blades on the reference surface are continuous planes.
[0014] In some embodiments, the height of the slit ranges from 3-8mm.
[0015] In some embodiments, the elastic blades are made of rubber.
[0016] In some embodiments, the main body further comprises a carrier plate integrally formed with the elastic blades, and a clamping body for detachably clamping the carrier plate, and the upper end of the clamping body is connected with a connecting head for connecting with a handle.
[0017] The cleaning head of the present application divides the lower end of the main body into a plurality of elastic blades through a slit, and the projections of the adjacent elastic blades on the reference surface of the main body are continuous, so that when the lower end of the elastic blades adheres to the surface to be cleaned and the cleaning head is moved in a direction perpendicular to the reference surface for sweeping, the plurality of elastic blades move closer to each other, so that the lower end of the main body is still shaped as a continuous cleaning edge, thereby preventing dirt from passing through the slit and achieving the same sweeping effect as the existing design. When encountering uneven places on the surface to be cleaned, the plurality of divided elastic blades can adaptively adhere to the uneven places on the surface to be cleaned, i.e. when encountering a protrusion on the surface to be cleaned, only the elastic blade corresponding to the protrusion is lifted in the state of adhering to the protrusion, and the remaining elastic blades still adhere to the remaining surface to be cleaned. When encountering a depression on the surface to be cleaned, the elastic blades already in the sweeping operation can further extend into the depression, and the remaining elastic blades still adhere to the remaining surface to be cleaned. Therefore, on uneven surfaces to be cleaned, the cleaning head of the present application can always adhere to the surface to be cleaned, thereby preventing gaps between the cleaning head and the surface to be cleaned and avoiding incomplete sweeping of dirt.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:
[0033] This application discloses a cleaning head, such as Figure 1 As shown, it includes a plate-shaped main body 1. Here, "plate-shaped" means that the main body 1 has a large area on two opposite sides, while the area on the other sides is smaller. Specifically, a thin, blade-shaped surface is formed on the lower end face of the main body 1 to perform scraping operations on the surface to be cleaned using this surface or attachments connected to it. Figure 1 , 2 As shown, the lower end of the plate-shaped main body 1 has several slits 11, which divide the lower end of the main body 1 into several elastic scrapers 12. The slits 11 can be simply cuts, meaning adjacent elastic scrapers 12 are in close contact, or they can be slot-shaped openings, meaning adjacent elastic scrapers 12 have a certain distance between them. The elasticity of the elastic scrapers 12 refers to the fact that when an external force drives or holds the main body 1 and presses its elastic scrapers 12 against the surface to be cleaned, the elastic scrapers 12 can deform to a certain extent, such as bending or shrinking. When the elastic scrapers 12 are no longer in contact with the surface to be cleaned or the pressure they receive is small, the elastic scrapers 12 can return to their deformed state or have a tendency to return to their previous state. Obviously, the material of the elastic scrapers 12 can be rubber or other materials with elastic deformation capabilities, or a spring or other structure that generates elastic force can be installed inside the elastic scrapers 12.
[0034] Furthermore, when the main body 1 is perpendicular to the surface to be cleaned, such as Figure 3As shown, the two opposite sides of the main body 1, which have a larger area, are projected onto the paper as lines. The vertical plane perpendicular to the paper is then used as the reference plane, and the direction of the cleaning head's scraping is... Figure 3 The left and right directions of the main body 1. For example... Figure 4 As shown, in this application, the projections of two adjacent elastic scrapers 12 on the reference plane are continuous, that is, the projections of two adjacent elastic scrapers 12 on the reference plane are connected or partially overlap. Figure 4 The diagram shows a state where the projections of two adjacent elastic scrapers 12 on the reference plane partially overlap. When the cleaning head is used for scraping, several elastic scrapers 12 form a continuous surface on a plane perpendicular to the direction of movement, i.e., the reference plane. These elastic scrapers 12 exist in two states: when the slit 11 is inclined to the reference plane, the elastic scrapers 12 can have a certain gap between them, or be adjacent and tightly pressed together. When using the elastic scrapers 12 to remove liquid dirt such as water stains, oil stains, or fine particulate dirt such as dust from the surface to be cleaned, the adjacent elastic scrapers 12 will stick together due to the resistance of the surface, meaning the gap between the elastic scrapers 12 disappears. This prevents dirt from passing through the elastic scrapers 12 through the slit 11, ensuring the scraping effect. Conversely, when the slit 11 is perpendicular to the reference plane, i.e., when all the elastic scrapers 12 are parallel to the reference plane, the elastic scrapers 12 must remain tightly pressed together, forming a continuous plane without gaps on the reference plane. This also prevents dirt from passing through the elastic scrapers 12 through the slit 11, ensuring the scraping effect. Regardless of the type of slit 11 mentioned above, when encountering uneven areas on the surface to be cleaned during scraping, such as protrusions, the elastic scraper 12 corresponding to the protrusion is obstructed by the protrusion, increasing its deformation and being lifted. Therefore, multiple elastic scrapers 12 remain in contact with the protrusion at each protrusion, while the elastic scrapers 12 at other positions, due to the division by the slit 11, are not affected by the elastic scrapers 12 corresponding to the protrusion and still remain in contact with the surface to be cleaned. This ensures that the cleaning head can always remain in contact with the surface to be cleaned, whether it is flat or uneven, through the elastic scrapers 12, without creating gaps at uneven areas, preventing dirt from being left on the uneven areas of the surface to be cleaned.
[0035] Specifically, such as Figure 1 , 2 As shown in Figure 4, a first form of the slit 11 is provided, wherein the projections of two adjacent elastic scrapers 12 at the slit 11 on the reference plane partially overlap, that is, the slit 11 forms a line along... Figure 3 or Figure 4The direction section of the middle horizontal plane is approximately parallelogram shape, so that when viewed along the direction perpendicular to the reference plane, no gap can be seen between the elastic blades 12, that is, no gap is generated during wiping. At this time, since the slit 11 has a certain width, the shape is similar to a chute, in order to ensure that the adjacent two elastic blades 12 can be attached during wiping in the state of the slit 11, the angle between the extension direction of the chute of the slit 11 and the reference plane is not more than 90 degrees, and when the width of the slit 11 is wider, the angle between the extension direction of the chute of the slit 11 and the reference plane should be smaller, so that the overlapping part of the projections of the adjacent two elastic blades 12 on the reference plane is as large as possible, to avoid the generation of a gap through dirt between the elastic blades 12 due to the deformation of the elastic blades 12. Of course, it is also necessary to appropriately adjust the width of the slit 11 and the width of the overlapping part, so that when an uneven cleaning surface is encountered, the elastic blade 12 corresponding to the uneven part can smoothly disengage from the elastic blade 12 corresponding to the remaining part, to avoid that when the width of the slit 11 is too wide, the adjacent two elastic blades 12 cannot be attached, so that the dirt passes through the slit 11, or when the width of the overlapping part is too wide, the elastic blades 12 cannot disengage, so that the elastic blade 12 corresponding to the flat part on the cleaning surface is still subjected to a large friction force by the elastic blade 12 corresponding to the uneven part, thereby driving the elastic blade 12 corresponding to the flat part to also generate a large deformation, so that a gap is generated between the elastic blade 12 corresponding to the flat part and the cleaning surface, resulting in a decrease in cleaning effect. Through comparison and analysis of the size of the cleaning head on the market and the width of the different slits 11 and the width of the overlapping part on the existing cleaning head, for general liquid dirt and dust and other particulate impurities, a slit 11 width of less than 2 mm can ensure that the two elastic blades 12 on both sides of the slit 11 can be attached during wiping, and when the width of the overlapping part between the adjacent two elastic blades 12 is about 1.6 mm, the cleaning effect is best, and when the width is greater than 3 mm, the wiping effect on the uneven part of the general ground will be significantly reduced. Therefore, the width of the slit 11 in the present application should be kept within 0-2 mm, and the width of the overlapping part between the adjacent two elastic blades 12 should be kept within 3 mm, to ensure the wiping effect.
[0036] In addition, when the projections of the adjacent two elastic blades 12 at the slit 11 on the reference plane have a partial overlap, the slit 11 extends along Figure 3 or Figure 4The direction section of the middle horizontal plane can also be corrugated, that is, the slit 11 is shaped as a corrugated groove at the lower end of the main body 1. By setting the slit 11 as corrugated, that is, the opposite faces of the two adjacent elastic blades 12 are both corrugated, when the two elastic blades 12 are close to each other during sweeping, the corrugations between the elastic blades 12 form a mutual clamping state, so that the close state between the elastic blades 12 is maintained more stably, to further prevent the generation of gaps between the elastic blades 12.
[0037] In another embodiment provided in the present application, additionally, as shown in Figure 5 the third form of the slit 11 is provided, that is, the slit 11 is only a cut extending along the direction perpendicular to the reference plane, and in the state without external force, that is, without contacting the surface to be cleaned, the elastic blades 12 on both sides of the slit 11 remain close, the projections of the adjacent elastic blades 12 on the reference plane do not overlap, but remain in an adjacent close state, that is, along the direction perpendicular to the reference plane, the elastic blades 12 form a continuous surface. When cleaning is performed along the direction perpendicular to the reference plane, the elastic blades 12 will only deform in this direction, that is, the distance between the adjacent elastic blades 12 will not change, still maintaining the adjacent close state, at this time, the lower end of the cleaning head still forms a complete blade without obvious gaps, so that dirt cannot pass through the slit 11, and at the same time, when encountering uneven surfaces to be cleaned, the elastic blades 12 can still change as described above in the state of the two slits 11, to ensure the cleaning effect on uneven surfaces to be cleaned.
[0038] For the cleaning head in the present application, since its general use environment is a family environment, the uneven places on the ground, table top, glass and other surfaces to be cleaned will not have a large height difference from the overall surface to be cleaned, because along the Figure 3In the vertical direction, the height of the slit 11 does not need to be too large, because each elastic blade 12 essentially forms a cantilever structure connected to the main body 1, and a too large height of the slit 11 will make the elastic blade 12 have a large deformation capacity away from the main body 1, especially when the elastic blade 12 has a large self-weight or is made of soft material, the elastic blade 12 can be deformed without or with a small external force, so that the arrangement of the elastic blades 12 is scattered, so that the slit 11 cannot be reduced when the cleaning head is swept in the direction perpendicular to the reference plane, and the adjacent elastic blades 12 cannot be attached, so that the dirt passes through the slit 11, reducing the cleaning effect; and the height of the slit 11 cannot be too small, and a too small height will make the elastic blade 12 have a poor deformation capacity, and the cleaning effect is similar to that without the slit 11, therefore, through comparative analysis, the height of the slit 11 is kept at 4.8mm, and when the height of the slit 11 is less than 3mm, the deformation capacity of the elastic blade 12 will be similar to that of the existing design under the thickness of the commonly used elastic blade 12, therefore, the height of the slit 11 in the present application should be kept in the range of 3-8mm, which can ensure better cleaning effect and adaptability to uneven surfaces to be cleaned.
[0039] In some embodiments, in order to facilitate user operation, as shown in Figure 6 The main body 1 includes a carrier plate 13 and a clamping body 14, the carrier plate 13 is integrally formed with the elastic blade 12, and the clamping body 14 has a clamping cavity on the top, so that the carrier plate 13 can be detachably clamped in the clamping cavity of the clamping body 14, so that when any elastic blade 12 is damaged, it can be replaced by detaching the carrier plate 13 from the clamping body 14, avoiding the use cost caused by replacing the entire main body 1.
[0040] In addition, as shown in Figure 6 In order to adapt to the cleaning of large areas such as floors and windows, and the user cannot directly touch the surface to be cleaned, a connecting head 2 can be provided on the clamping body 14, which is used to connect with a handle, a grip and the like, so as to lengthen the cleaning head, so that the user can operate the cleaning head at a long distance by holding the handle, the handle is generally rod-shaped or tubular, therefore the shape of the connecting head 2 can be correspondingly set as tubular, so that one end of the handle is inserted into the connecting head 2, and the two are tightly fitted or connected in a detachable manner by using a clamping or the like. Of course, for small areas such as desktops and bed surfaces, which are easy for the user to reach, a holding part can be directly provided on the upper end of the main body 1 for the user to hold and operate.
