Description

Technical Field

[0001] This application relates to the field of pet product technology, specifically to a cat litter dust filter. Background Technology

[0002] With the ever-growing number of cat owners, cat litter has become an essential consumable for most cat-owning households. However, due to the natural physical properties of cat litter products, regardless of price or quality, they all generate a significant amount of dust during use. This not only affects indoor air quality but may also pose potential health hazards to cats and family members.

[0003] Currently, many cat owners use tools such as drain baskets or strainers as filters when removing cat litter dust. While these tools can filter out some dust, to completely remove most of the dust from the cat litter, people often need to shake the litter multiple times. This approach is not only inefficient and labor-intensive, but also tedious, causing considerable trouble for cat owners. Utility Model Content

[0004] Therefore, this application provides a cat litter dust removal filter to solve the problems of low working efficiency and cumbersome process in existing cat litter dust removal devices.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A cat litter dust collector filter, wherein the dust collector filter is a hollow structure with one end open and the other end closed, and is divided into a fixed section at the rear and an insertion section at the front.

[0007] The fixed section is a cylindrical structure, and the rear end of the fixed section is an open end, which is used to connect to the end of the connecting pipe of the vacuum cleaner.

[0008] The insertion section is used to insert into the interior of the cat litter. The front end of the insertion section is a closed end, and the outer wall of the insertion section is provided with a plurality of first filter holes. The plurality of first filter holes are alternately distributed according to the pore size and are used to filter dust in the cat litter.

[0044] Example 1

[0045] A cat litter dust filter, which is installed on a vacuum cleaner and is a vacuum cleaner connector accessory;

[0046] like Figures 1-4 As shown, the dust filter is a hollow structure with one end open and the other end closed, and is divided into a fixed section 1 at the rear and an insertion section 2 at the front. The fixed section 1 is a cylindrical structure, and the rear end of the fixed section 1 is an open end 101, which is used to connect to the end of the connecting pipe of the vacuum cleaner (connected by plugging). The insertion section 2 is used to insert into the inside of the cat litter. The front end of the insertion section 2 is a closed end, and the outer wall of the insertion section 2 is provided with a number of first filter holes 3, which are alternately distributed according to the hole size to filter dust in the cat litter.

[0047] Preferably, a plurality of first filter holes 3 are arranged in groups, each group of first filter holes 3 has the same pore diameter, and the pore diameters of adjacent groups of first filter holes 3 are different.

[0048] More preferably, each group of first filter holes 3 is evenly distributed along the radial direction of the insertion section 2.

[0049] Preferably, the pore size of the first filter hole 3 is in the range of 20-30 mesh.

[0050] Preferably, the longitudinal section of the insertion segment 2 is a trapezoidal structure, and it is a right-angled trapezoid.

[0051] Preferably, the dust filter is made of stainless steel or plastic.

[0052] Preferably, the front part of the fixed section 1 is provided with a plurality of second filter holes 4 on the side close to the insertion section 2.

[0053] More preferably, the first filter hole 3 and the second filter hole 4 are circular, square or elliptical in shape.

[0054] Example 2

[0055] Example 2 is basically similar to Example 1, except that: Figures 5-8 As shown in Example 2, the longitudinal section of the inserted segment 2 is an isosceles trapezoidal structure.

[0056] Preferably, the diameter of the insertion segment 2 gradually increases from back to front.

[0057] The wider front end of insertion section 2 provides a larger contact area, which better captures and filters dust in the cat litter, and makes it more stable during insertion and removal, reducing the possibility of shaking, improving ease of use and filtration efficiency.

[0058] Example 3

[0059] Example 3 is basically similar to Example 1, except that: Figures 9-12 As shown in Example 3, the longitudinal section of the inserted segment 2 is a wedge-shaped structure.

[0060] Preferably, the diameter of the insertion segment 2 gradually increases from back to front.

[0061] Example 4

[0062] Example 4 is basically similar to Example 1, except that: Figures 13-16 As shown in Example 4, the longitudinal section of the inserted segment 2 is a triangular structure.

[0063] The operating principle of the above embodiment is as follows: the rear end of the fixed section 1 of the dust filter is directly inserted into the end of the connecting pipe of the vacuum cleaner, and the insertion section 2 of the dust filter is inserted into the inside of the cat litter. Then the vacuum cleaner is started, and the dust in the cat litter is filtered through several first filter holes 3 on the outer wall of the insertion section 2.

[0064] In summary, this application has at least the following advantages:

[0065] 1. This dust filter is used to connect to a vacuum cleaner. By connecting to the vacuum cleaner's connecting tube, it can quickly suck up dust from the cat litter, greatly improving filtration efficiency, effectively reducing the harm of dust in the cat litter to people and pets, and also reducing labor intensity. At the same time, several first filter holes are distributed alternately according to the size of the holes, which makes it easy to suck up all the dust particles of different sizes in the cat litter, thereby effectively separating the dust and cat litter.

[0066] 2. The insertion section is designed as a trapezoidal, wedge-shaped, or triangular structure to ensure that it can be easily inserted into the cat litter, improving ease of use and filtration efficiency. In actual use, this significantly enhances the user experience and reduces the workload of cat owners when cleaning cat litter dust. Furthermore, the insertion section is designed with a gradually increasing diameter from back to front, which provides a larger contact area and further improves the filtration effect.

[0067] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
