Description

Technical Field

[0001] This invention relates to the field of pet product development and application technology, and in particular to a quantitative evaluation device for the stickiness performance of cat litter to the bottom and walls, and its usage method. Background Technology

[0002] Adhesion is fundamental to the effectiveness of cat litter. In practical use, when cat urine penetrates the litter layer and comes into contact with the bottom of the litter box, it easily sticks to the bottom, a phenomenon known as "bottom sticking." Simultaneously, due to differences in cat urination habits, cats may urinate on the sides of the litter box, causing litter to stick to the walls, a phenomenon known as "wall sticking." Litter clumps adhering to the bottom and walls are difficult to scoop out, and cleaning is time-consuming and laborious. Therefore, the ability of cat litter to stick to the bottom and walls has gradually become one of the indicators for evaluating its overall performance, and is also an important factor affecting its market price and market share, receiving significant attention from manufacturers and users.

[0003] Chinese invention patent CN118542249A discloses a whole starch cat litter granule composition and its preparation method, and introduces a sensory evaluation method for the cat litter's stickiness to the bottom and sides by scooping out clumps with a litter scoop and touching the contact surface of the clumps. This patent classifies the cat litter's stickiness into three levels: A, B, and C. For level A, the litter clumps are easily scooped out, and the contact surface is not sticky to the touch; for level B, the litter clumps are easily scooped out, but the contact surface is sticky to the touch; for level C, the litter clumps are difficult to scoop out, become loose when scooped out, and the contact surface is sticky to the touch.

[0004] The applicant has identified at least the following technical problems in the existing technology: The evaluation of cat litter's stickiness to the bottom and sides is still based on qualitative perception and description according to experience, lacking quantitative evaluation techniques, methods, and means. This restricts the research, development, production, and application of high-quality, non-sticky cat litter, and also causes difficulties in the quality evaluation, market supervision, and legal dispute adjudication of cat litter products. Summary of the Invention

The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A quantitative evaluation device for the adhesion performance of cat litter to the bottom and walls includes a base plate, a molded component, a base, and a tensile testing machine.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention. In the description of this invention, it should be understood that the terms "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicate the orientation or positional relationship based on the appendix.

[0021] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Reference Figures 1 to 5 The present invention provides a quantitative evaluation device for the adhesion performance of cat litter to the bottom and walls, including a base plate 1, a molded part 2, a base 3 and a tensile testing machine.

[0023] The molded part 2 is placed on the base plate 1 and the two are combined to form an assembly. The interior of the assembly can be used to hold cat litter, which facilitates the conduct of corresponding tests.

[0024] The end of the molded part 2 away from the base plate 1 can be detachably connected to the base 3. After the cat litter fills the assembly, a test solution is added to the cat litter. After the cat litter and the test solution are mixed, a cat litter clump is formed and adheres to the assembly. After the assembly and the cat litter clump are inverted 180°, the molded part 2 can be connected to the base 3, thereby fixing the combined structure of the molded part 2, the base plate 1 and the cat litter.

[0025] The end of the base plate 1 away from the molded part 2 can be detachably connected to the tensile testing machine. After the molded part 2 is connected to the base 3, the base plate 1 is connected to the tensile testing machine. The tensile testing machine can pull the base plate 1 upward to separate the base plate 1 from the cat litter clump. The tensile testing machine can record the maximum value of the tensile force, which is recorded as the adhesive force.

[0026] It is worth noting that after the base plate 1 separates from the cat litter clump, the base plate 1 is actually covered with cat litter. By weighing the base plate 1 in its initial state and the base plate 1 covered with cat litter separately, the amount of cat litter adhering to the base plate 1 can be calculated, that is, the mass (weight) of the litter.

[0027] Thus, by using the quantitative evaluation device for cat litter adhesion performance, the bonding force between the cat litter clumps and the base plate 1, as well as the mass (weight) of cat litter adhering to the base plate 1, can be quantitatively measured. Therefore, a quantitative evaluation of cat litter adhesion performance can be achieved. This method is simple and quick to operate, and has the advantages of accurate data and quantitative conclusions.

[0028] The quantitative evaluation device for cat litter sticking to the bottom and walls can obtain data on the performance of cat litter sticking to the bottom and walls, and can be used to evaluate the performance of cat litter sticking to the bottom and walls, providing experimental equipment and data support for the establishment of a quantitative evaluation system for the performance of cat litter sticking to the bottom and walls.

[0029] As an optional implementation, the base plate 1 is preferably a disc structure, with a first surface 11 and a second surface 12 formed at both ends of its axial direction. The first surface 11 is a plane and forms contact with the molded part 2. The second surface 12 is a plane and has a bolt hole 121 provided in its center. The bolt hole 121 is connected to the upper tension rod of the tensile testing machine by bolts.

[0030] As an optional implementation, the molded part 2 includes a large-diameter section 21 and a small-diameter section 22 connected to each other, forming a stepped hole structure in appearance. At the same time, the large-diameter section 21 and the small-diameter section 22 have stepped molded grooves 23 inside them for accommodating cat litter.

[0031] The outer end face of the large diameter segment 21 forms the third surface 211, and the outer end face of the small diameter segment 22 forms the fourth surface 221. When the base plate 1 and the molded part 2 form an assembly, the fourth surface 221 comes into contact with the first surface 11, and cat litter can be poured in and fill the molded groove 23.

[0032] When the molded part 2 is in an inverted state, the large diameter section 21 can be connected to the base 3.

[0033] As an optional implementation, the base 3 includes a connecting part 31 and a support leg 32 connected to the bottom of the connecting part 31. The connecting part 31 has a slot 311, and the large diameter section 21 can be inserted into the slot 311 to fix the assembly.

[0034] The top surface of the connecting part 31 forms a fifth surface 312, which is connected to the base of the tensile testing machine, and the bottom surface of the support leg 32 forms a sixth surface 321.

[0035] As an alternative embodiment, the base plate 1 is made of polyethylene, polypropylene or polyamide, and the roughness of the first surface 11 ranges from 12.5 to 25, and the roughness of the second surface 12 ranges from 200 to 400.

[0036] As an optional embodiment, the molded part 2 is made of polyethylene, polypropylene or polyamide, the roughness of the third surface 211 is in the range of 200-400, and the roughness of the fourth surface 221 is in the range of 12.5-25.

[0037] As an optional implementation, the base 3 is made of carbon steel, and the roughness of the fifth surface 312 ranges from 200 to 400, and the roughness of the sixth surface 321 ranges from 200 to 400.

[0038] This invention also provides a method for using a quantitative evaluation device for the stickiness performance of cat litter to the bottom and walls, comprising the following steps: S1. Weigh the base plate 1 using a weighing device and record the weight value as W1. Place the base plate 1 flat on the workbench with the first side 11 facing upwards.

[0039] The weighing device here is preferably a balance with a graduation value of 0.001g, thereby further ensuring the accurate reading of the weight value. The first side 11 of the base plate 1 faces upward and the second side 12 faces downward, which facilitates its combination with the molded part 2. After being flipped 180° up and down, the first side 11 becomes downward and the second side 12 becomes upward. At this time, the bolt holes 121 of the second side 12 are also set upward, which facilitates the connection with the upper tension rod of the tensile testing machine.

[0040] S2. Place the molded part 2 flat on the first surface 11 of the base plate 1 with the large diameter section 21 on top, and keep the center of the molded part 2 and the base plate 1 aligned, so that the molded part 2 and the base plate 1 form an assembly.

[0041] The centered molded part 2 and the base plate 1 can ensure accurate positioning. The small diameter segment 22 of the molded part 2 is located at the bottom, and the fourth surface 221 of the small diameter segment 22 is located at the bottommost point, forming contact with the first surface 11 of the base plate 1. After the molded part 2 is placed securely, it forms an assembly with the base plate 1.

[0042] S3. Connect base 3 to the base of the tensile testing machine.

[0043] In actual operation, the fifth surface 312 of the base 3 is facing upwards, and it is fixed to the base of the tensile testing machine. The test force resolution of the tensile testing machine is preferably 1 / 500000FS, so as to ensure that the value of the adhesive force F1 detected by subsequent tests is more accurate.

[0044] S4. Pour cat litter into and fill the molding slot 23 of the molding part 2, so that the upper surface of the cat litter is flush with the third surface 211.

[0045] In actual operation, the cat litter is poured into the forming groove 23 in an orderly manner. The cat litter will first fill the small stepped section of the forming groove 23, and then fill the large stepped section. It can also be fully filled by shaking it slightly, and finally achieve the effect of spreading it out, so that the upper surface of the cat litter is level with the third surface 211, thus completing the cat litter filling operation.

[0046] S5. Drip the test solution into the cat litter to obtain cat litter clumps, and after a preset time, flip the assembly with the cat litter clumps 180° up and down.

[0047] In actual operation, a volumetric measuring instrument is used, preferably a pipette or a pipette tube. The volumetric measuring instrument draws 20 mL of 1% sodium chloride solution at a temperature of 36-40℃, and then the solution is transferred to a burette. The burette outlet is adjusted to the center of the forming groove 23, and the outlet is 3 cm away from the cat litter surface. The burette is opened to allow the test solution to flow out at the fastest speed. After all the test solution has flowed out, the timing is started. The preset time is preferably 180 seconds. After the time is up, the assembly with cat litter clumps is slowly rotated 180° up and down. During this process, the cat litter clumps are always connected to the assembly.

[0048] S6. Connect the large-diameter section 21 on the molded part 2 after it has been flipped 180° up and down to the slot 311 on the base 3. Use bolts to connect the bolt hole 121 on the base plate 1 to the upper tension rod of the tensile testing machine. After waiting for the preset time to be reached, start the tensile testing machine. The preset time is preferably 360 seconds. After the time is reached, the upper tension rod of the tensile testing machine can pull the base plate 1 upward until the base plate 1 separates from the cat litter clump. Read the maximum value of the tensile force of the tensile testing machine and record it as the adhesion force F1.

[0049] At the end of this step, the base plate 1 detaches from the cat litter clumps, while cat litter remains stuck to the base plate 1.

[0050] S7. Remove the base plate 1, and use a weighing device to weigh the base plate 1 and the cat litter attached to the base plate 1. The weight value is recorded as W2.

[0051] S8. Calculate the adhesion amount ΔW, ΔW=W2-W1.

[0052] After adopting the above-described method, the quantitative evaluation device for cat litter adhesion performance can quantitatively determine the adhesion force between the cat litter clump and the base plate 1, as well as the mass (weight) of cat litter adhering to the base plate 1. Therefore, it can achieve a quantitative evaluation of the cat litter adhesion performance. This method is simple and quick to operate, and has the advantages of accurate data and quantitative conclusions.

[0053] The quantitative evaluation device for cat litter sticking to the bottom and walls can obtain data on the performance of cat litter sticking to the bottom and walls, and can be used to evaluate the performance of cat litter sticking to the bottom and walls, providing experimental equipment and data support for the establishment of a quantitative evaluation system for the performance of cat litter sticking to the bottom and walls.

[0054] Example 1: The base plate 1 was made of polyamide (nylon 66). The roughness of the first surface 11 and the second surface 12 of the base plate 1 was measured using a roughness tester. The results showed that the roughness (Ra) of the first surface 11 was 22.5 and the roughness (Ra) of the second surface 12 was 273.

[0055] Polyamide (Nylon 66) was selected to process the molded part 2. The roughness of the third surface 211 and the fourth surface 221 of the molded part 2 was measured by a roughness tester. As a result, the roughness (Ra) of the third surface 211 was 280 and the roughness (Ra) of the fourth surface 221 was 20.8.

[0056] The base 3 is made of carbon steel. The roughness of the fifth surface 312 and the sixth surface 321 of the base 3 is measured by a roughness tester. The results show that the roughness (Ra) of the fifth surface 312 is 297 and the roughness (Ra) of the sixth surface 321 is 315.5.

[0057] A spherical bentonite cat litter was selected as the cat litter used in this experiment.

[0058] The usage method is as follows: S1. Weigh the base plate 1 using a balance with a scale division of 0.001g and record the weight value as W1. As a result, the weight of the base plate 1 is W1 = 115.552g. Place the base plate 1 flat on the workbench with the first side 11 facing upwards.

[0059] S2. Place the molded part 2 flat on the first surface 11 of the base plate 1 with the large diameter section 21 on top, and keep the center of the molded part 2 and the base plate 1 aligned, so that the molded part 2 and the base plate 1 form an assembly.

[0060] S3. Connect base 3 to the base of the tensile testing machine, so that the test force resolution of the tensile testing machine reaches 1 / 500000FS.

[0061] S4. Pour the spherical bentonite cat litter into and fill the molding slot 23 of the molding part 2, so that the upper surface of the spherical bentonite cat litter is flush with the third surface 211.

[0062] S5. Use a pipette or pipette to draw 20 mL of 1% sodium chloride solution at 38°C, then transfer the solution to a burette. Adjust the burette outlet to the center of the forming groove 23 and keep the outlet 3 cm away from the cat litter surface. Open the burette to allow the test solution to flow out at the fastest speed. Start timing after all the test solution has flowed out. After 180 seconds, slowly rotate the assembly with the spherical bentonite cat litter clumps 180° up and down.

[0063] S6. Connect the large-diameter segment 21 on the molded part 2 after it has been flipped 180° up and down to the slot 311 on the base 3. Use bolts to connect the bolt hole 121 on the base plate 1 to the upper tension rod of the tensile testing machine. After waiting for 360 seconds after the start of the timing in step S5, start the tensile testing machine. The upper tension rod of the tensile testing machine can pull the base plate 1 upward until the base plate 1 separates from the cat litter clump. Read the maximum value of the tensile force of the tensile testing machine and record it as the adhesive force F1. As a result, the maximum value of the tensile force of the tensile testing machine is 12.452N, which is recorded as the adhesive force F1 = 12.452N.

[0064] S7. Remove the base plate 1 and weigh the base plate 1 and the cat litter attached to it using a weighing device. The weight value is recorded as W2. As a result, W2 = 115.903g.

[0065] S8. Calculate the adhesion amount ΔW, ΔW=W2-W1=115.903–115.552=0.351g.

[0066] Therefore, as a result, the two quantitative indicators of the adhesion performance of spherical bentonite cat litter are: adhesion force F1 = 12.452 N and adhesion amount ΔW = 0.351 g.

[0067] Example 2: Based on Example 1, the spherical bentonite cat litter was replaced with non-sticky modified spherical bentonite cat litter, while other parameters remained the same as in Example 1.

[0068] As a result, the adhesion force of the obtained anti-sticking modified spherical bentonite cat litter was F1=2.309N, and the adhesion amount was ΔW=0.025g.

[0069] Example 3: Based on Example 1, the spherical bentonite cat litter was replaced with crushed bentonite cat litter, while other parameters remained the same as in Example 1.

[0070] As a result, the bonding force of the obtained bentonite-crushed cat litter was F1=4.327N, and the adhesion amount was ΔW=0.997g.

[0071] Example 4: Based on Example 1, the spherical bentonite cat litter was replaced with non-sticky modified bentonite crushed cat litter, while other parameters remained the same as in Example 1.

[0072] As a result, the adhesion force of the obtained non-sticky modified bentonite crushed cat litter was F1=2.138N, and the adhesion amount was ΔW=0.036g.

[0073] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
