Description

Technical Field

[0001] This invention belongs to the field of cat litter box technology, and particularly relates to an air purification device for cat litter boxes. Background Technology

[0002] As the needs of urban families for pet home care continue to upgrade and become more refined, litter boxes, as essential pet supplies for cat-owning households, have gradually become an important part of modern homes. However, traditional litter boxes still have a series of significant technical pain points and functional defects in actual use: First, in the cleaning and maintenance process, these products are prone to producing a noticeable odor from pet feces, accompanied by fine dust and potentially bacteria-containing aerosol particles raised during litter use. More importantly, traditional designs generally lack efficient and integrated pollutant collection and air purification mechanisms, causing odors to quickly spread throughout the indoor space after use, seriously damaging indoor air quality and environmental hygiene. In addition, floating dust and microorganisms may not only cause respiratory discomfort, sneezing, or allergic reactions in pets, especially cats, but may also pose a potential threat to the health of household residents, especially children, the elderly, and people with allergies, thus reducing the overall comfort and safety of living with pets.

[0003] Current litter box technology primarily focuses on automatic cleaning, such as mechanically shoveling and collecting waste. However, these designs often neglect the more critical issues of odor control and dust suppression. Meanwhile, while stand-alone air purifiers offer some air purification capabilities, their bulky size and space requirements make them difficult to deploy around the litter box, hindering their efficiency in addressing localized pollution particles and odors. Furthermore, these purifiers lack intelligent coordination with the litter box, failing to automatically start / stop or adjust operating modes based on litter usage. This results in low purification efficiency, uneconomical energy use, and significantly reduced user convenience and overall experience.

[0004] Therefore, integrating small and medium-sized air purification functions with cat litter boxes can effectively achieve the automated linkage of pollutant collection, targeted purification, and cleaning processes. This not only provides an effective way to solve the shortcomings of traditional products in deodorization, antibacterial and air quality control, but also precisely meets the increasing demand of modern families for pet health care, providing a practical R&D idea and important development direction for the intelligent and healthy upgrading of pet products.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] This embodiment provides an air purification device for cat litter boxes. The device adopts a modular structure and can be easily and detachably installed on the side of the cat litter box 1000. Through the coordinated design of the mounting component 10, the first panel 11, and the second panel 12, a more rational and efficient gas flow path and purification circulation are achieved. Specifically, the first panel 11 is provided with a specially structured embedding groove 112, which allows the entire first panel 11 to be stably and accurately installed in the designated position of the cat litter box 1000. At the same time, this detachable structure greatly facilitates the user's daily maintenance and replacement of core functional components such as the filter 20 and the negative pressure fan 30. The construction of the embedding groove 112 not only enhances the connection stability between the device and the cat litter box 1000, but also makes it compatible with cat litter boxes 1000 of various sizes and shapes, significantly improving the product's versatility and flexibility in actual use.

[0034] Combination Figures 1 to 6 As shown, the air purification device for cat litter boxes provided in this embodiment mainly includes core functional components such as a mounting component 10, a filter 20, and a negative pressure fan 30. The mounting component 10, serving as the main support structure, is designed to be detachably fitted with a first panel 11 and a second panel 12, facilitating quick installation and disassembly by the user, as well as routine cleaning, maintenance, or component replacement. The mounting component 10 and the first panel 11 form a first gas region 100, while the mounting component and the second panel 12 form a second gas region 200. The first gas region 100 and the second gas region 200 are structurally connected through a specific channel. The first gas region 100 is mainly used to receive and guide polluted gases from inside the cat litter box 1000 that need purification, while the second gas region 200 is responsible for introducing fresh, clean air from outside. Under the continuous action of the negative pressure fan 30, the polluted gas in the first gas zone 100 is drawn in and actively flows to the second gas zone 200. During this process, the two gases are fully mixed to form a uniform mixed airflow, thus creating stable and ideal aerodynamic conditions for subsequent high-efficiency filtration and deep purification.

[0035] In this embodiment, the filter 20 is detachably mounted on the mounting component 10, specifically through common mechanical connection methods such as snap-fit ​​or threaded connection. This design is not only simple in structure and convenient in operation, but also helps to reduce the difficulty of maintenance and replacement, thereby significantly improving the maintainability and service life of the equipment. Simultaneously, the filter 20 is arranged within the second gas zone 200, and its main function is to efficiently filter the gas flowing through this zone, effectively removing dust, particulate matter, and other impurities to ensure the purity of the gas medium. Furthermore, the negative pressure fan 30 is also detachably mounted on the mounting component 10, with a similar installation method to the filter 20, such as through snap-fit ​​or threaded connection, facilitating disassembly and replacement. The negative pressure fan 30 and the filter 20 are spatially opposite each other, forming a stable and efficient airflow channel. Through collaborative work, the negative pressure fan 30 generates negative pressure to draw in gas, while the filter 20 filters impurities from the drawn-in gas, jointly achieving efficient gas extraction and filtration functions. In this embodiment, the filter 20 preferably uses HEPA high-efficiency filter material and is combined with activated carbon to give the filter 20 a deodorization function, so as to ensure that the gas in the second gas zone 200 can be filtered more thoroughly and efficiently to meet the high standard of air purification requirements.

[0036] Specifically, in the structural design adopted in this embodiment, the first panel 11 and the main body of the litter box 1000 are assembled through a detachable connection. This design fully considers the actual needs of users for cleaning and maintaining the device during daily use, making the disassembly and installation of the first panel 11 simpler and faster, significantly improving the practicality of the product and the user experience. Furthermore, multiple neatly arranged air inlets 111 are evenly distributed throughout the entire surface area of ​​the first panel 11. These appropriately sized and scientifically laid-out holes can efficiently guide the odorous gases and humid air accumulated inside the litter box 1000 into the first gas area 100 above it, providing a stable and unobstructed flow channel for subsequent gas guidance and treatment processes. Meanwhile, the second panel 12 is arranged inside the device in a manner relatively parallel to the first panel 11. Its surface is precisely formed with several air inlet slots 121 of a certain length and width. These slotted structures allow fresh air from the external environment to be continuously and evenly introduced into the second gas region 200, thereby achieving effective exchange and thorough mixing of the internally accumulated gas and the external fresh air, ensuring the basic conditions for gas treatment. Furthermore, a well-designed gas exhaust port 101 is specifically provided on the mounting component 10 of the overall structure. This port is located at the end of the airflow path of the device, used to smoothly discharge the mixed and filtered gas to the external environment, thereby ensuring smooth airflow within the entire device, thorough gas filtration, and high reliability of the final purification effect, fully meeting the product's preset functional standards and performance requirements.

[0037] In this embodiment, the negative pressure fan 30 is precisely positioned within a specific space between the mounting component 10 and the first panel 11. This rational layout not only fully utilizes the space but also ensures the stability of the equipment operation. The negative pressure fan 30 and the mounting component 10 work closely together to form a clearly defined third gas region 300. Although this third gas region 300 is entirely located within the first gas region 100, its structural design maintains its independence and integrity. Its boundaries are clear, and it is completely separated from the first gas region 100 through physical isolation, ensuring that the two regions do not communicate with each other in the gas flow path and effectively preventing gas mixing or mutual interference.

[0038] Combination Figure 5 and Figure 6As shown, in the specific structure of this embodiment, the mounting component 10 is provided with two sets of through holes 102. These through holes 102 are used to achieve effective communication between the first gas region 100 and the second gas region 200, ensuring that gas can flow smoothly from the first gas region 100 to the second gas region 200. Simultaneously, the mounting component 10 also provides a central through hole 103. The main function of this through hole is to connect the third gas region 300 with the second gas region 200, further optimizing the gas flow path. The central through hole 103 is designed as a circular opening, its position precisely corresponding to the negative pressure fan 30, so that the negative pressure fan 30 can efficiently draw and transport gas through this through hole. Furthermore, the gas discharge port 101 is arranged at the top of the mounting component 10. This design helps to smoothly discharge the treated gas in the third gas region 300, thereby ensuring the gas circulation and exchange efficiency of the entire system.

[0039] In practical use, the air purification device for the litter box in this embodiment is quickly installed on the side of the litter box 1000 via the embedding groove 112 on the first panel 11, ensuring the overall structure is stable. When the negative pressure fan 30 is activated, the odorous gas inside the litter box 1000 enters the first gas zone 100 through the air inlet 111 on the first panel 11 under negative pressure. Simultaneously, external air is introduced into the second gas zone 200 through the air inlet groove 121 on the second panel 12. The two gases converge and mix at the through hole 102 of the mounting component 10, and then flow through the HEPA filter 20 in the second gas zone 200. The HEPA filter 20, with its fine fiber structure, efficiently traps dust particles, odor molecules, and some microorganisms in the gas. The purified mixed gas is drawn into the independent third gas zone 300 through the annular central through hole 103, and finally discharged as clean air through the gas exhaust port 101 at the top of the mounting component 10. The entire process enables rapid capture and purification of localized pollution sources in the litter box 1000. The detachable filter 20 and negative pressure fan 30 design allow users to easily replace components during routine maintenance, effectively reducing operating costs and complexity. Furthermore, the modular connection between the device and the litter box 1000 allows it to be compatible with different brands and sizes of litter box 1000 products, enhancing the product's market applicability and user acceptance.

[0040] In summary, the air purification device for cat litter boxes in this embodiment achieves highly efficient and targeted treatment of odors from the litter box 1000 through the gas mixing design of the first gas zone 100 and the second gas zone 200 and the construction of independent purification channels. Its modular and detachable structure not only simplifies the maintenance process of core components and lowers the user's operating threshold, but also enhances compatibility with different litter boxes 1000 through detailed designs such as the embedded slot 112. The collaborative working mechanism of the HEPA filter 20 and the negative pressure fan 30 ensures the stability and continuity of purification efficiency, while the independent division of the three gas zones optimizes airflow organization and avoids secondary pollution. This design concept, which integrates high-efficiency purification, convenient maintenance, and wide compatibility, not only creates a healthier living environment for pet families but also provides a replicable solution for the technological upgrading of the pet products industry, promoting the further development of intelligent pet care products.
