Description

Technical Field

[0001] This invention belongs to the field of purification and sterilization technology, specifically a smart air purification and sterilization system for cat litter boxes based on sensor control. Background Technology

[0002] With increasingly compact urban living spaces and a rapid increase in the number of pet owners, more and more families are choosing to keep pet cats indoors. However, as an essential daily facility, the cat litter box inevitably produces odorous gases containing ammonia, hydrogen sulfide, volatile organic compounds (VOCs) during use, which seriously affects indoor air quality and living comfort. To solve this problem, existing technologies mostly use the method of venting the cat litter box exhaust to the outside through the air conditioning holes, window gaps, or sewer pipes reserved in the building to achieve rapid odor removal.

[0003] However, not all residences have usable air conditioning vents, window openings, or suitable drainage and ventilation channels. Especially in high-rise apartments, older residences, or scenarios where structural modifications to the building are limited, the above-mentioned ventilation methods are often difficult to implement or have problems such as inconvenient installation, poor sealing, and backflow of odors. In addition, if the odor that has not been fully treated is released back into the room, it will not only fail to improve air quality, but may also cause secondary pollution. In response to the above pain points, there is an urgent need to develop an indoor deodorization and purification device specifically for cat litter boxes. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent air purification and sterilization system for cat litter boxes based on sensor control, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent air purification and sterilization system for cat litter boxes based on sensor control, comprising a cat litter box, a cylindrical outer shell, a first filter core, a second filter core, a top cover, a filter net, a pipe interface, and a filter plate;

[0006] The first filter cartridge is slidably placed inside the cylindrical outer shell to remove odors, cat litter dust and harmful bacteria from the cat litter box;

[0007] The second filter cartridge is slidably placed inside the first filter cartridge to deodorize the gas from the cat toilet.

[0010] As a further preferred embodiment of this technical solution: the cylindrical outer shell is provided with an exhaust port for discharging purified gas, and there are several groups of exhaust ports, which are evenly distributed on the cylindrical outer shell. At the same time, the cylindrical outer shell is provided with a gripping opening for indoor personnel to pick up the cylindrical outer shell.

[0011] As a further preferred embodiment of this technical solution: a supporting edge plate is fixedly connected to the top of the first filter core, and a limiting edge plate is fixedly connected to the top of the second filter core, wherein the limiting edge plate is attached to the upper surface of the supporting edge plate.

[0012] As a further preferred embodiment of this technical solution: the cylindrical outer shell is provided with a sliding groove, and the top cover is installed on the sliding groove by a sliding slider embedded inside, while the end of the slider away from the sliding groove is fixed to the top cover;

[0013] As a further preferred embodiment of this technical solution: the top of the cat toilet is equipped with an air supply pipe through an interface, and an exhaust fan for extracting gas from the cat toilet is installed inside the interface of the cat toilet. At the same time, the end of the air supply pipe away from the cat toilet is slidably connected to the pipe interface.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, through a multi-stage sliding combination structure of a first filter core, a second filter core, a filter net, and a filter plate, odor molecules, cat litter dust, hair, and large particulate impurities generated in the cat litter box can be removed layer by layer; at the same time, an ultraviolet germicidal lamp is integrated and its start and stop are intelligently controlled by an ultraviolet light infrared sensor. The sterilization program is automatically started after the cat leaves, effectively inactivating common zoonotic pathogenic microorganisms such as Escherichia coli, Staphylococcus aureus, Escherichia coli, Aspergillus flavus, Toxoplasma gondii oocysts, and hookworm larvae, significantly reducing the risk of cross-infection between humans and pets.

[0019] 2. In this invention, by equipping the exhaust fan with an infrared sensor and the ultraviolet lamp with an infrared sensor, the exhaust fan and ultraviolet lamp are automatically activated only after the cat is detected leaving the litter box, thus avoiding the harm of ultraviolet rays to pets or humans. At the same time, it achieves on-demand operation, energy saving and consumption reduction, and users do not need to operate manually, truly realizing "unobtrusive" intelligent purification.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example

[0027] Please see Figures 1-4 As shown, the present invention provides a technical solution: an intelligent air purification and sterilization system for cat litter boxes based on sensor control, including a cat litter box 1, a cylindrical outer shell 2, a first filter core 3, a second filter core 4, a top cover 5, a filter net 6, a pipe interface 7, and a filter plate 8.

[0028] The first filter cartridge 3 is slidably placed inside the cylindrical outer shell 2 to remove odors, cat litter dust and harmful bacteria from the cat toilet 1;

[0029] The second filter cartridge 4 is slidably placed inside the first filter cartridge 3 to deodorize the gas in the cat toilet 1;

[0030] The top cover 5 is slidably disposed inside the cylindrical outer shell 2, while the filter bag 6 is fixedly connected to the bottom of the top cover 5 through it for deodorization;

[0031] The pipe interface 7 is fixed to the end of the top cover 5 away from the filter bag 6, while the filter plate 8 is fixed inside the filter bag 6 to filter large particulate impurities in the gas of the cat toilet 1.

[0032] Furthermore: The filter bag 6 contains activated carbon and baking soda granules to filter and purify the gas in the cat litter box 1. At the same time, the filter plate 8 can also prevent external dust from entering the filter components inside the cylindrical outer shell 2 when the filter device is not in use.

[0033] In this embodiment, specifically: the cylindrical outer shell 2 is provided with an exhaust port 201 for discharging purified gas, and the exhaust port 201 is provided in several groups, and the several groups of exhaust ports 201 are evenly distributed on the cylindrical outer shell 2. At the same time, the cylindrical outer shell 2 is provided with a gripping opening 202 for indoor personnel to pick up the cylindrical outer shell 2.

[0034] Furthermore, several sets of exhaust holes 201 are distributed in a ring on the cylindrical outer shell 2, and two sets of gripping ports 202 are provided, which are respectively located at the front and rear ends of the cylindrical outer shell 2.

[0035] In this embodiment, specifically: a support edge plate 301 is fixedly connected to the top of the first filter core 3, and a limiting edge plate 401 is fixedly connected to the top of the second filter core 4, with the limiting edge plate 401 attached to the upper surface of the support edge plate 301.

[0036] Further: The outer surface of the second filter cartridge 4 is in contact with the surface of the filter fibers inside the first filter cartridge 3.

[0037] In this embodiment, specifically: the cylindrical outer shell 2 is provided with a sliding groove 9, and the top cover 5 is installed in the sliding groove 9 by a sliding slider 10 embedded inside, while the end of the slider 10 away from the sliding groove 9 is fixed to the top cover 5.

[0038] Furthermore, by embedding the slider 10 into the slide groove 9, it is necessary to align it with the groove opening and insert it vertically before sliding. This makes the positioning more precise and the connection more reliable. In addition, the surface of the slide groove 9 is textured, which can prevent the top cover 5 from sliding upward and opening when the filter component is running inside the cylindrical shell 2.

[0039] In this embodiment, specifically: an air supply pipe 11 is installed on the top of the cat toilet 1 through an interface, and an exhaust fan for extracting gas from the cat toilet 1 is installed in the interface of the cat toilet 1. At the same time, the end of the air supply pipe 11 away from the cat toilet 1 is slidably connected to the pipe interface 7.

[0040] Furthermore, the air supply pipe 11 is a 50mm diameter flexible hose, and the exhaust fan is a type of silent fan.

[0041] In this embodiment, specifically: a mode selection switch button 12 is fixedly connected through the cat toilet 1, and an exhaust fan infrared sensor for controlling the exhaust of gas in the cat toilet 1 is installed on the side of the cat toilet 1 away from the mode selection switch button 12. At the same time, the exhaust fan infrared sensor is electrically connected to the mode selection switch button 12.

[0042] A UV sterilization switch 13 is fixedly connected through the cat litter box 1, and a UV lamp infrared sensor is installed on the side of the cat litter box 1 away from the UV sterilization switch 13. The UV lamp infrared sensor is electrically connected to the UV sterilization switch 13.

[0043] Furthermore, the mode selection switch button 12 and the ultraviolet sterilization switch 13 are equipped with intelligent ring lights, which distinguish the exhaust mode and operating status through three different colored ring lights. The red ring light indicates that the normally open mode is in operation, the green ring light indicates that the intelligent sensing mode is in standby mode, and the yellow ring light indicates that the intelligent sensing mode is in operation.

[0044] In this embodiment, specifically: the cat toilet 1 is provided with a power cord interface 14 for connecting a power cord.

[0045] Further: Power cord interface 14 is a 5521DC type power interface.

[0046] Working principle or structural principle: When a cat enters the litter box 1 to use the litter box, the infrared sensor of the exhaust fan detects the activity signal. When the cat leaves the litter box 1, the silent exhaust fan automatically starts and draws out the gas containing odors, dust, and bacteria from the litter box 1 through the air pipe 11. The gas first enters the cylindrical outer shell 2 and flows through the filter screen 6, where the activated carbon and baking soda granules further deodorize the litter box. Large particles are intercepted by the filter plate 8 installed inside the cylindrical outer shell 2. Subsequently, most of the odors, litter dust, and other impurities are removed by the sliding first filter core 3 and the second filter core 4 nested within it. Harmful microorganisms are eliminated, and the filter plate 8 can prevent external dust from entering the interior when the equipment is not in use. The purified gas is discharged through multiple sets of exhaust holes 201 evenly distributed on the cylindrical outer shell 2. In addition, the ultraviolet light infrared sensor can sense the environment and link the ultraviolet sterilization module to perform timed or on-demand sterilization. The entire system uses the mode selection switch button 12 and the ultraviolet sterilization switch 13 in conjunction with the intelligent ring light to realize three operating status indicators - red for normally open mode, green for intelligent standby mode, and yellow for sensing operation, taking into account energy saving and efficient purification, thereby realizing intelligent and automated purification and sterilization of the air in the cat toilet 1.
