Description

Technical Field

[0001] The utility model relates to the technical field of pet appliances, and more specifically, to a cat litter cleaning appliance. Background Art

[0002] As one of the small animals loved by humans, more and more people raise cats, and a cat litter shovel is one of the essential appliances for raising cats. After the cat litter absorbs urine and clumps, the breeder uses the cat litter shovel to remove it and then fills in fresh and clean cat litter.

[0003] The cat litter shovel directly opens sieve holes at the bottom. When in use, the cat litter is shoveled, and the handle is grasped and shaken, so that the clumped cat litter remains on the shovel body and is then poured out. In practice, the cat litter is prone to breakage after clumping, resulting in urine clumps of different sizes. If the sieve holes are too large, the cat litter particles can be quickly filtered out, but small urine clumps may follow and fall. If the sieve holes are too small, it takes a long time to filter out the cat litter particles, and the clean cat litter cannot be fully sifted down, causing waste. The clean cat litter and the clumped cat litter are mixed together, bringing great inconvenience to cleaning the cat litter box and making it easier for the shovel to become blocked. Various improved designs have emerged in the industry.

[0004] For example, the cat litter shovels provided by patents with publication numbers CN220000317U, CN220712437U, CN220174085U, CN209489288U, etc. directly open two groups of sieve holes with different size specifications on the shovel surface to achieve hierarchical screening; but in practice, when shoveling cat litter, the cat litter often covers the entire shovel surface. Especially when shoveling small particle cat litter, it is also easy to leak from the position of the large sieve holes, and users need to specifically adjust the angle of the shovel to concentrate the cat litter in a certain area, or it takes multiple times to completely shovel out the small urine clumps, and the operation is not convenient.

[0005] The patent with publication number CN204482636U provides a cat litter shovel with adjustable holes, which is equipped with an adjusting device that can move along the length direction of the shovel body and adjust the length of the sieve holes; moving the adjusting device can block part of the sieve holes to make the sieve holes smaller. The patent with publication number CN210695406U provides a cat litter shovel, including an upper shovel body and a lower shovel body. The upper shovel body is located in the lower shovel body and is slidably connected to the lower shovel body in a left-right movable manner. Sieve holes are provided on both the upper and lower shovel bodies. After the upper and lower shovel bodies move relative to each other, the mesh size of the cat litter shovel can be changed. Such designs all require cooperating with movable components on the cat litter shovel. The number of components increases, the structure is relatively complex, the production and installation are inconvenient, and the cat litter is also easy to stick to each component, making it inconvenient to clean the cat litter shovel itself.

[0006] The patent with the publication number CN213548943U provides an efficient cat litter shovel. The shovel body consists of a front sieve section, an occlusion boss, and a rear sieve section. The front sieve section and the rear sieve section are respectively fixedly connected to both sides of the occlusion boss. The first sieve holes and the second sieve holes with different pore sizes are used on the front sieve section and the rear sieve section to filter the lumps of different sizes of cat litter. This design uses the occlusion boss to prevent small lumps from easily running to the back and large lumps from being blocked by the occlusion boss. However, in practice, the occlusion boss will form an obvious obstacle to the cleaning of cat litter. When pouring the cat litter, the fine cat litter is easily stuck inside the occlusion boss and difficult to pour out. The user needs to tilt at a large angle or perform knocking and shaking to completely pour it out. Moreover, the cat litter is easily stuck inside the boss and in the groove formed under the occlusion boss, resulting in relatively difficult self-cleaning of the cat litter shovel and affecting the convenience of use for the user. Summary of the Utility Model

[0007] 1. Technical problems to be solved by the utility model

[0008] In view of the situation that cat litter is prone to adhesion, inconvenient pouring and cleaning when using a cat litter shovel in the prior art, the present utility model intends to provide a cat litter cleaning tool. The cat litter shovel adopting this design is convenient for quickly pouring and cleaning the cat litter, and the cat litter is not easily stuck on the shovel body, making it more convenient to use.

[0009] 2. Technical solution

[0010] To achieve the above object, the technical solution provided by the present utility model is as follows:

[0011] A cat litter cleaning tool of the present utility model includes: a shovel body, the shovel body has a front shovel part and a rear shovel part. Multiple groups of first sieve holes are provided on the front shovel part, and multiple groups of second sieve holes are provided on the rear shovel part. Specifically, in this design, the upper surfaces of both the front shovel part and the rear shovel part have a cat litter bearing surface, and the height of the cat litter bearing surface on the rear shovel part is higher than the height of the cat litter bearing surface on the front shovel part; a transition connecting part is connected between the front shovel part and the rear shovel part. The heights of both ends of the upper surface of the transition connecting part in the front-rear direction are different. The rear end of the transition connecting part is the high position end, and the front end of the transition connecting part is the low position end. The front end of the transition connecting part is connected to the front shovel part, and the rear end of the transition connecting part is connected to the rear shovel part.

[0012] In this application, the overall shovel surface is designed with a lower front and a higher rear, and a transition connecting part is used for transition connection in the middle, so that no obstruction will be formed at the transition connecting part when pouring out cat litter, and the cat litter on the front shovel part and the rear shovel part can be poured out smoothly. More preferably, the average width of the second sieve holes on the rear shovel part is greater than the average width of the first sieve holes on the front shovel part. When circular sieve holes are used, the width of the sieve holes here refers to the aperture diameter. When other shaped sieve holes are used, in terms of the sieve hole extension length being not less than the extension width, it is preferred that the width of the second sieve holes is greater. In practice, the widths of multiple first sieve holes can be exactly the same or different; the widths of multiple second sieve holes can be exactly the same or different. It should be added that in this design, the average width of the second sieve holes that play the main screening function on the rear shovel part, that is, the second sieve holes occupying more than 50% of the screening area, is greater than the average width of the first sieve holes that play the main screening function on the front shovel part. In practice, various design forms can be adopted. For example, the width of each second sieve hole is the same, the width of each first sieve hole is the same, and the width of the second sieve holes is greater than the width of the sieve holes; or the widths of multiple second sieve holes on the rear shovel part are different, the widths of multiple first sieve holes on the front shovel part are different, and the minimum width of the second sieve holes is not less than the minimum width of the first sieve holes; or the widths of most of the second sieve holes on the rear shovel part are greater than the widths of most of the first sieve holes on the front shovel part, but there are a few second sieve holes with widths not greater than the widths of the first sieve holes, etc. All are within the range where the average width of the second sieve holes in this design is greater than the average width of the first sieve holes on the front shovel part.

[0013] In this design, the larger second sieve holes are arranged on the rear shovel part with a higher height, and the smaller first sieve holes are arranged on the front shovel part with a lower height. The front shovel part serves as a small urine mass screening area, and the rear shovel part serves as a large urine mass screening area. When shoveling cat litter, first shovel deeply to mainly use the rear shovel part to quickly screen out large urine masses, and then shovel shallowly to mainly use the front shovel part to screen small urine masses. At this time, the transition connecting part serves as the front and rear demarcation. The lower front and higher rear help to prevent a large number of small urine masses from entering the rear shovel part, and it has a one-way guiding effect on large urine masses without affecting the entry of large urine masses into the rear shovel part area. More importantly, when the cat litter is shoveled, the user needs to pour the urine masses on the shovel surface into the trash can. The height of the rear end of the transition connecting part is consistent with the height of the rear shovel part, and the height of the front end is consistent with the height of the front shovel part. Whether the urine masses are concentrated in the front shovel part or the rear shovel part area, no obstruction will be formed at the transition connecting part when pouring downwards. The transition connecting part can even guide the pouring of cat litter downwards, and the urine masses and cat litter will not get stuck inside the transition connecting part, so that the cat litter can be quickly cleaned. In practice, it is further preferred that the front shovel part, the rear shovel part and the transition connecting part all adopt a flat upper surface design. The upper surfaces of the front shovel part, the transition connecting part and the rear shovel part are continuously transitioned in sequence, and the three form an uninterrupted continuous surface. Specifically, an injection molding integrated design can be adopted, which is not easy to form fine cat litter blockage on the shovel body itself; no groove-shaped structure will be formed at the bottom of the transition connecting part, avoiding the situation that cat litter gets stuck in the groove during the shoveling process and is inconvenient to clean, etc., and the use convenience is greatly improved.

[0014] More optimally, the upper surface of the transition connecting part is an inclined extension surface, specifically along the front-back direction of the shovel body. The height of the transition connecting part gradually increases from the front end to the rear end. Specifically, the upper surface of the transition connecting part can adopt forms such as a plane, an arc surface, a wavy surface, or a stepped surface. Setting the transition connecting part as an inclined transition surface can help enhance the one-way guiding effect from front to back. When deeply shoveling and screening large urine clumps, it is more conducive to the accumulation of large urine clumps on the rear shovel part, so as to quickly screen. Secondly, in the dumping direction from back to front, no obstruction or occlusion will be formed, which is convenient for cleaning and dumping the cat litter. Further, sieve holes are also formed on the transition connecting part, such as the same first sieve holes formed on the front shovel part, so that the transition connecting part area also has a screening function, increasing the screening area.

[0015] In a more preferred design of the present application, the length extension direction of multiple groups of second sieve holes on the rear shovel part is not parallel to the front-back direction of the shovel body; or / and, the length extension direction of multiple groups of first sieve holes on the front shovel part is not parallel to the front-back direction of the shovel body. In practice, there will be some urine clumps in the shape of approximate spheres in the cat litter urine clumps. When the cat litter needs to be dumped after screening, the rear end of the cat litter shovel is lifted and tilted for dumping, and the cat litter slides forward along the front-back direction to the lower end at the front. When the sieve holes also extend in the front-back direction, the length direction of the sieve holes is completely parallel to the dumping direction of the cat litter shovel, and it is easy for the cat litter to slide off. Especially during the process of the user screening the cat litter and before dumping the cat litter into the trash can after screening, once the user shakes or tilts, it is easy for the cat litter to slide off in advance along the sieve hole direction, which may cause the cat litter to scatter on the ground. In this design, the length direction of the sieve holes is not parallel to the front-back direction of the cat litter shovel, preferably perpendicular to the front-back direction. At this time, the screened cat litter will not easily slide off along the length of the sieve holes, but can be stably carried on the shovel surface area until it is dumped, avoiding scattering on the ground before dumping and improving the cleaning efficiency.

[0016] During the screening process, the size and density settings of the sieve holes also affect the screening efficiency. In this design, the area of the hollow plane formed by multiple groups of second sieve holes on the rear shovel part occupies more than 70% of the overall area of the cat litter bearing surface on the rear shovel part; or / and, the area of the hollow plane formed by multiple groups of first sieve holes on the front shovel part occupies more than 70% of the overall area of the cat litter bearing surface on the front shovel part, thus ensuring sufficient screening area and improving the screening efficiency. In this design, it can be specifically preferred that on the front shovel part or / and on the rear shovel part or / and on the transition connecting part, that is, some areas among the three or all three are simultaneously provided, and two columns of sieve holes are symmetrically arranged on both sides along the front-back length direction of the shovel body. Each column includes multiple sieve holes spaced along the front-back length direction of the shovel body, and each sieve hole extends along the left-right width direction of the shovel body. The sieve holes in this design adopt a design similar to the vein of a leaf. The length of each sieve hole extends along the left-right width direction of the shovel body and is basically close to half of the width of the shovel body. By using long strip-shaped sieve holes, on the basis of reducing the number of sieve holes, the sieve hole area is maximized as much as possible, and the area occupied by the connecting ribs between the holes on the shovel surface is minimized as much as possible. This can not only further improve the screening efficiency, but also reduce the contact area between the cat litter and the connecting ribs of the shovel surface, reduce the adhesion of the cat litter in the shovel surface area. Even if there is a small amount of cat litter adhered to the edge of the sieve hole for a long time, since the sieve hole is long strip-shaped and has a relatively wide size, it will not significantly affect the screening efficiency of the sieve hole, and the convenience is higher.

[0017] Preferably in practice, the angle between the upper surface of the front shovel part and the horizontal plane is not less than the angle between the upper surface of the rear shovel part and the horizontal plane, including the state where the upper surface of the front shovel part and the upper surface of the rear shovel part are parallel, and the angle between the upper surface of the front shovel part and the horizontal plane is greater than the angle between the upper surface of the front shovel part and the horizontal plane. Further, the upper surfaces of both the rear shovel part and the front shovel part are horizontal planes, with a beautiful and simple shape, without obstruction during shoveling cat litter, and effective screening can be achieved by simply shaking the shovel after shoveling; when dumping the cat litter, the user does not need to tilt the shovel body greatly, and can dump the cat litter by slightly tilting, which is more rapid and convenient. In practice, it can also be selected that the upper surface of the rear shovel part is set as a horizontal plane, and the upper surface of the front shovel part is set as an inclined plane, and the inclined direction is that the height gradually increases from front to back. Or, the upper surfaces of both the rear shovel part and the front shovel part are inclined planes with the height gradually increasing from front to back, and the inclination angles of the two are parallel, or the angle between the rear shovel part and the horizontal plane is larger. This can effectively ensure that there is no obstruction between the rear shovel part and the front shovel part when dumping the cat litter, which is more conducive to the rapid sliding of the cat litter from the top, and the cat litter can slide down without the user tilting the shovel body greatly.

[0018] In coordination with the gradient design of the upper surface of the shovel body, further, the height of the bottom surface of the rear shovel part is higher than that of the bottom surface of the front shovel part, and the heights of the two ends of the bottom surface of the corresponding transition connection part are different. The low-position end of the bottom surface of the transition connection part is connected to the front shovel part, and the high-position end of the bottom surface of the transition connection part is connected to the rear shovel part. Preferably, the bottom surfaces of the front shovel part, the transition connection part, and the rear shovel part are continuously transitioned in sequence. At this time, preferably, the front shovel part, the rear shovel part, and the transition connection part have the same thickness, which is more convenient for processing, the structure is more concise and beautiful, and a single-sided inclined guiding surface will also be formed at the bottom between the transition connection part and the rear shovel part, rather than forming a groove-shaped area with inward depression and two-sided blocking walls, avoiding the situation that cat litter gets stuck inward during shoveling and is not easy to clean up.

[0019] In practice, further, the two sides and the rear end of the shovel body are also surrounded by a retaining part to prevent cat litter from directly falling from the four sides of the shovel body, and the front end of the retaining part has an inclined part with a gradually increasing height from front to back, so as to facilitate guiding when pushing the shovel forward; along the front-rear direction of the shovel body, preferably, the extension length of the retaining part is less than the extension length of the shovel body, so that the front end of the front shovel part extends forward beyond the retaining part, and there is a thin shoveling plane at the shoveling opening, which is more convenient for the shovel body to be inserted into the cat litter and shovel forward.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] The following further describes the present utility model in conjunction with embodiments.

[0029] Embodiment

[0030] Combined with Figures 1-3 , a cat litter cleaning tool for this embodiment includes: a shovel body 100. The shovel body 100 has a front shovel part 110 and a rear shovel part 120. A plurality of groups of first sieve holes 111 are provided on the front shovel part 110, and a plurality of groups of second sieve holes 121 are provided on the rear shovel part 120. The upper surfaces of the front shovel part 110 and the rear shovel part 120 both have a cat litter bearing surface, and the height of the cat litter bearing surface on the rear shovel part 120 is higher than the plane height of the cat litter bearing surface on the front shovel part 110. A transition connecting part 130 is connected between the front shovel part 110 and the rear shovel part 120. The heights of the two ends of the upper surface of the transition connecting part 130 in the front-rear direction are different. The rear end of the transition connecting part 130 is the high end, and the front end of the transition connecting part 130 is the low end. The front end of the transition connecting part 130 is connected to the front shovel part 110, and the rear end of the transition connecting part 130 is connected to the rear shovel part 120. More preferably, the upper surfaces of the front shovel part 110, the transition connecting part 130, and the rear shovel part 120 are all flat surfaces, and the upper surfaces of the front shovel part 110, the transition connecting part 130, and the rear shovel part 120 are continuously transitioned in sequence to form an integral non-discontinuous continuous surface as the screening surface, such as being processed by integral injection molding.

[0031] In practical cat litter shovels, a handle 200 for easy grasping is generally provided on the shovel body 100. The front-rear direction mentioned in this embodiment is combined with Figure 1As shown, it refers to the length extension direction of the handle 200. The direction where the handle 200 is close to the shovel body 100 is the front, and the direction where the handle 200 is away from the shovel body 100 is the back. In this design, the upper surface of the shovel body 100 is designed with a lower front and a higher back, and the transition connecting part 130 is used for transition connection to play a one-way guiding role. Further preferably, the minimum width of the second sieve holes 121 on the rear shovel part 120 is greater than the minimum width of the first sieve holes 111 on the front shovel part 110. Specifically, it can be selected that the width of each second sieve hole 121 is greater than the width of the first sieve hole 111; large sieve holes are opened on the rear shovel part 120 as the large urine mass screening area, and small sieve holes are opened on the front shovel part 110 as the small urine mass screening area. The front shovel part 110, the rear shovel part 120 and the transition connecting part 130 are all designed with a planar shape, making the rear shovel part 120 the highest plane of the shovel surface. After the shoveling action is completed, when pouring out the cat litter outward, just slightly lift the rear end of the shovel body 100, and the cat litter can then fall off the shovel body 100 downward. Especially at the transition connecting part 130 at the height boundary, its rear end is flush with the rear shovel part 120 to form an integral plane. When there is cat litter on the rear shovel part 120, it will not cause an inner obstacle to the pouring of the cat litter. The cat litter can quickly pass through the transition connecting part 130 and finally fall off the shovel surface, and it is not easy to adhere to the rear side of the transition connecting part 130, which is convenient for pouring the cat litter. And the entire shovel surface is composed of smooth planes, without grooves or blocky structures, which is more convenient for self-cleaning of the shovel body 100. When performing the shoveling action in this design, the user can quickly distinguish the screening areas by controlling different depths of shoveling. Generally, the large urine masses are screened first and then the small urine masses. First, shovel deeply downward with a large depth, then the large urine masses can still be concentrated backward without being blocked on the rear shovel part 120 for quick screening. After shoveling the large urine masses, then shovel shallowly with a small depth, so that the small urine masses are blocked by the transition connecting part 130 and are basically concentrated on the front shovel part 110 for screening, and the user operation is also relatively convenient.

[0032] Combined Figure 2 , furthermore, preferably, the upper surface of the transition connecting part 130 extends obliquely, specifically along the front-back direction of the shovel body 100. The height of the transition connecting part 130 gradually rises from the front end to the rear end. The transition connecting part 130 has a guiding effect on the large urine masses, which is more convenient for the large urine masses to be concentrated backward on the rear shovel part 120, and the height of the rear end is relatively high. Such an inclined setting will not cause an obstacle to the later pouring of the cat litter, is more conducive to pouring the cat litter, and is more convenient for cleaning the shovel body 100. The transition connecting part 130 can specifically adopt forms such as an obliquely extending plane, an arc surface, a stepped surface, a wavy surface, etc. Furthermore, sieve holes are also opened on the transition connecting part 130, specifically, small sieve holes with the same specifications as the first sieve holes 111 are set, increasing the distribution area of the sieve holes and improving the screening efficiency.

[0033] In practice, the shape and distribution of the sieve holes can adopt various forms. Preferably, the length extension direction of multiple groups of second sieve holes 121 on the rear shovel part 120 is not parallel to the front-back direction of the shovel body 100; or / and, the length extension direction of multiple groups of first sieve holes 111 on the front shovel part 110 is not parallel to the front-back direction of the shovel body 100. In this embodiment, preferably, the leaf vein-shaped distribution as shown in Figure 2 is adopted. On the front shovel part 110 or / and the rear shovel part 120 or / and the transition connection part 130, that is, any one or all of the three can adopt this leaf vein-shaped distribution. Specifically, two columns of sieve holes are symmetrically arranged on both sides along the front-back length direction of the shovel body 100. Each column includes multiple sieve holes spaced along the front-back length direction of the shovel body 100. Each sieve hole extends along the left-right width direction of the shovel body 100. The so-called extension along the left-right width direction of the sieve hole along the shovel body 100 includes both the case where the sieve hole extends along the width direction completely perpendicular to the front-back direction, and can also be as shown in Figure 2 where it shows an inclined extension in the left-right width direction. The sieve holes in the same column are preferably arranged in a parallel manner. In this way, the length extension direction of the sieve holes is staggered with the front-back pouring direction of the cat litter, avoiding the situation that the cat litter easily slips off the shovel surface due to the user's unsteady grip or shaking before pouring the cat litter. And with such a design, the extension length of each sieve hole is basically close to half of the width of the shovel body. On the basis of reducing the number of sieve holes, the sieve hole area is increased as much as possible. The hollow plane area formed by multiple groups of second sieve holes 121 on the rear shovel part 120 occupies more than 70% of the overall area of the upper surface of the rear shovel part 120; or / and, the hollow plane area formed by multiple groups of first sieve holes 111 on the front shovel part 110 occupies more than 70% of the overall area of the upper surface of the front shovel part 110, thereby improving the screening efficiency, and the area of the connecting ribs between the sieve holes can be effectively reduced, reducing the contact area with the cat litter, thereby reducing the adhesion of the cat litter on the shovel surface, avoiding the phenomenon of cat litter blockage, and also being more conducive to the self-cleaning of the shovel body 100. The vein-shaped distribution of the sieve holes is also more beautiful and concise. In this embodiment, the multiple "or / and" schemes mentioned refer to the situation where they can be simultaneously present or can be selectively present.

[0034] In practice, preferably, the angle between the upper surface of the front shovel part 110 and the horizontal plane is not less than the angle between the upper surface of the rear shovel part 120 and the horizontal plane. Further preferably, the upper surfaces of both the rear shovel part 120 and the front shovel part 110 are horizontal planes, with a beautiful and simple shape, and it is also more convenient to pour the cat litter after shoveling, and it is not easy to accumulate and adhere to the fine cat litter.

[0035] Corresponding to the stepped design on the upper surface of the shovel body 100, as shown in Figure 3As shown in the figure, further, the height of the bottom surface of the rear shovel part 120 is higher than that of the bottom surface of the front shovel part 110. The heights of the two ends of the bottom surface of the transition connection part 130 are different. The front end of the bottom surface of the transition connection part 130 is connected to the front shovel part 110, and the rear end of the bottom surface of the transition connection part 130 is connected to the rear shovel part 120. More preferably, the bottom surfaces of the front shovel part 110, the transition connection part 130, and the rear shovel part 120 also adopt a planar design, and the three planes are continuously transitioned. Similarly, it is preferred that the bottom surface of the transition connection part 130 extends in an inclined manner, and the height gradually increases backward along the front-rear direction, so that a single-sided inclined guiding surface is also formed between the bottom of the transition connection part 130 and the rear shovel part 120, avoiding situations such as fine cat litter getting stuck under the transition connection part 130 and being difficult to clean. Specifically, the bottom surface of the transition connection part 130 can also adopt forms such as an inclined extended plane, an arc surface, a stepped surface, or a wavy surface. Further preferably, the respective thickness regions of the front shovel part 110, the rear shovel part 120, and the transition connection part 130 are the same, which is more convenient for processing, the product structure is thinner and lighter, and it is also more labor-saving to use.

[0036] In practice, the two sides and the rear end of the shovel body 100 are surrounded by a retaining part 140, and preferably, the front end of the retaining part 140 has an inclined part with a height gradually increasing from front to back, so as to facilitate guiding when pushing the cat litter forward. Along the front-rear direction of the shovel body 100, the extending length of the retaining part 140 is less than the extending length of the shovel body 100, so that the front end of the front shovel part 110 extends forward beyond the retaining part 140, and there is a thin cat litter shoveling plane at the shoveling opening, which is more convenient for the shovel body to insert into the cat litter and shovel the cat litter forward.

[0037] The cat litter shoveling tool of this embodiment, on the basis of meeting the requirement of realizing the grading and screening of cat litter size, through structural optimization design, simplifies the structure of the shovel body 100 as much as possible and does not add complex accessories, while improving the convenience of subsequent cat litter dumping and shovel surface cleaning of the cat litter shovel, thereby optimizing the user experience.

[0038] The above schematically describes the present invention and its embodiments. This description is not restrictive, but only one of the embodiments of the present invention. In fact, it is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments to this technical solution without creative work under the premise of not departing from the creative purpose of the present invention, they should all fall within the protection scope of the present invention.
