Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a cat litter dust detection device. Background Technology

[0002] As a daily necessity for pet cats, the dust-generating performance of cat litter directly affects pets' health and user experience. In cat litter research and development and quality control, dust testing is a key step in evaluating product performance. Currently, the industry generally uses the free-fall test (pouring test) as the main means of dust detection. This method simulates the scenario of users pouring cat litter daily, where a certain amount of cat litter is dropped freely from a fixed height (usually 0.5-1 meter) onto an empty container or the ground, and the dust phenomenon is observed and recorded. During the test, the operator needs to visually judge the significance of the dust (e.g., low, medium, high) as the basis for evaluating the product's dust performance. This method is widely used in production testing and product comparison due to its simplicity and low cost, and has become a common basic testing standard in the cat litter industry.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] The free fall test method relies on subjective judgment by the naked eye and lacks quantitative data support, which may lead to different conclusions by different testers or the same person in different environments. The repeatability and accuracy of the test results are difficult to guarantee. Secondly, the free fall test cannot distinguish the particle size distribution of dust particles, making it difficult to assess the potential harm of fine particulate matter (such as PM2.5) to the respiratory tract of pets.

[0005] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, this utility model proposes a cat litter dust detection device, which solves the problems mentioned in the background technology.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A cat litter dust detection device includes a dark box, a feeding mechanism mounted on the dark box for simulating cat litter dumping, and an industrial camera for detecting cat litter dust.

[0009] The darkroom includes a litter box for collecting cat litter, an adapter enclosure covering the outside of the litter box, and a light source assembly encapsulated on top of the enclosure. The feeding mechanism and the industrial camera are respectively located on adjacent sides of the enclosure. The enclosure is composed of four white matte acrylic sheets glued together, and the inner walls of the white matte acrylic sheet for mounting the industrial camera and the two adjacent white matte acrylic sheets are covered with black light-absorbing velvet.

[0010] The feeding mechanism consists of a connecting pipe that is inclined into the dark box and a storage assembly that is mounted on the top of the connecting pipe via a flange in the vertical direction through a solenoid valve.

[0011] Preferably, the outer wall of the recycling box is enclosed with an inherent rubber liner. Cat litter may generate impact vibrations during dumping; the rubber liner absorbs energy through elastic deformation, reducing rigid collisions between the recycling box and the enclosure, preventing structural loosening or noise. Simultaneously, the high friction of the rubber material prevents the recycling box from sliding within the enclosure, ensuring the stability of the device during dumping and avoiding dust data deviations caused by displacement. Furthermore, it fills the gap between the enclosure and the outer wall of the recycling box to a certain extent, improving the sealing effect.

[0012] Preferably, the light source assembly includes a cover, a diffuser plate, and several LED strips. The diffuser plate covers and is installed at the opening at the bottom of the cover, forming a cavity for mounting the LED strips. The LED strips are arranged in a single-row rectangular array. The diffuser plate can be made of milky-white acrylic sheet. The diffuser plate enables uniform diffusion of light from the single-row rectangular array of LED strips, transforming a point light source into a surface light source. The light source area covers the entire recycling box area, ensuring clear imaging of dust particles within the dark chamber.

[0013] Preferably, the storage assembly consists of a hopper and a cover plate that is hinged to the hopper via a torsion spring hinge.

[0014] Preferably, a first magnetic block is embedded at each of the two corners on the top surface of the hopper away from its hinge, and a second magnetic block is embedded at each of the two corners on the bottom surface of the cover plate away from its hinge, which is magnetically compatible with the first magnetic block.

[0015] The torsion spring hinge and cover plate on the top surface of the hopper, as well as the first and second magnetic blocks that can be magnetically matched with each other, help to achieve immediate sealing of the hopper after the cat litter is poured out, so as to block the exchange of external air, prevent airflow interference, and ensure that the feeding process is controllable and repeatable.

[0016] The beneficial effects of this utility model are:

[0017] The technical solution of this utility model achieves quantitative detection of cat litter dust by combining a dark box design with an industrial camera and a feeding mechanism. The high-precision imaging of the industrial camera replaces visual observation, effectively avoiding subjective judgment differences and significantly improving the accuracy of test results. At the same time, using a white matte acrylic board as a background and covering the three sides of the inner side of the enclosure away from the background board with black light-absorbing velvet effectively eliminates ambient light interference and enhances the imaging contrast of dust particles, ensuring clear capture and particle size analysis of fine particulate matter (such as PM2.5), and providing reliable data support for assessing the potential harm of cat litter to pets' respiratory tract.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-6 This utility model provides a technical solution: a cat litter dust detection device, including a dark box 100 and a feeding mechanism 200 mounted on the dark box 100 for simulating cat litter dumping and an industrial camera 300 for detecting cat litter dust. The dark box 100 includes a collection box 110 for collecting cat litter, a barrier 120 adapted to cover the outside of the collection box 110, and a light source assembly 130 covering and encapsulating the top of the barrier 120. The feeding mechanism 200 and the industrial camera 300 are respectively mounted on the barrier 110. On the two adjacent sides of 20, the enclosure 120 is composed of four white matte acrylic panels 1210 glued together. The white matte acrylic panel 1210 for mounting the industrial camera 300 and the inner sidewalls of the two adjacent white matte acrylic panels 1210 are covered with black light-absorbing velvet 1220. The feeding mechanism 200 consists of a connecting pipe 210 that is connected to the dark box 100 in an inclined direction and a storage assembly 230 that is flanged in a vertical direction and mounted on the top of the connecting pipe 210 through a solenoid valve 220.

[0036] Based on the above structural configuration, the cat litter dust detection device consists of a dark box 100, a feeding mechanism 200, and an industrial camera 300. The dark box 100 constructs the detection environment, and its enclosure 120 is formed by four white matte acrylic panels 1210 glued together. The inner sides of the three sides adjacent to the mounting surface of the industrial camera 300 are covered with black light-absorbing velvet cloth 1220, forming a high-contrast imaging background and effectively eliminating ambient light interference. A backlit projection detection system can be constructed within the dark box 100, with the industrial camera 300 facing the white background panel. The top light source 130 shines directly, and dust particles appear as dark shadows. In the feeding mechanism 200, the connecting pipe 210 is connected to the dark box 100 in an inclined direction, simulating the path of cat litter falling freely to the recycling box 110. The operator can control the opening and closing of the storage component 230 through the solenoid valve 220. Specifically, during operation, the operator loads a measured amount of cat litter into the storage component 230. After activating the solenoid valve 220, the cat litter slides down the connecting pipe 210 to the recycling box 110, simulating a cat litter dumping scenario, and dust particles appear as dark shadows. After being illuminated by a light source, the dust particles inside the chamber 100 are captured and imaged by an industrial camera 300. A black light-absorbing velvet cloth 1220 enhances the contrast between the particles and the background, ensuring clear identification of fine particulate matter (such as PM2.5). The system uses image analysis algorithms to quantify the particle size distribution and quantity of dust particles, replacing traditional subjective judgment by the naked eye, thereby achieving an accurate assessment of the dust emission performance of cat litter. This cat litter dust detection device, through the design of the dark chamber 100 combined with the industrial camera 300 and the feeding mechanism 200, achieves quantitative detection of cat litter dust. The industrial camera 300 high-precision imaging replaces visual observation, effectively avoiding subjective judgment differences and significantly improving the accuracy of test results. At the same time, using a white matte acrylic sheet 1210 as a background board and covering the three sides of the enclosure 120 away from the background board with black light-absorbing velvet cloth 1220 effectively eliminates ambient light interference and enhances the imaging contrast of dust particles, ensuring clear capture and particle size analysis of fine particulate matter (such as PM2.5), providing reliable data support for assessing the potential harm of cat litter to pets' respiratory tract.

[0037] It should be noted that the system and image analysis algorithm mentioned above are existing mature technologies, and their structure and working principle are not the innovations of this utility model. Therefore, they are not shown in the accompanying drawings and the above description. The protection scope of this utility model is only for the specific structural features related to simulation testing that are explicitly defined in the claims.

[0038] Furthermore, the outer wall of the recycling box 110 is enclosed with an inherent rubber liner 1110.

[0039] Furthermore, the light source assembly 130 includes a cover 1310, a diffuser plate 1320, and a plurality of LED light strips 1330. The diffuser plate 1320 covers and is installed at the opening at the bottom of the cover 1310 and encloses a cavity for mounting the plurality of LED light strips 1330. The plurality of LED light strips 1330 are arranged in a single row of rectangular array.

[0040] Furthermore, the storage assembly 230 consists of a hopper 2310 and a cover plate 2330 that is hinged to the hopper 2310 via a torsion spring hinge 2320.

[0041] Furthermore, a first magnetic block 2340 is embedded in each of the two corners of the top surface of the hopper 2310 away from its hinge, and a second magnetic block 2350 that is magnetically compatible with the first magnetic block 2340 is embedded in each of the two corners of the bottom surface of the cover plate 2330 away from its hinge.
