Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to an intelligent cat litter box. Background Technology

[0002] Smart litter boxes are modern pet supplies designed to provide cat-owning families with a more efficient and convenient litter disposal solution. They are typically equipped with advanced sensors and automatic processing systems that monitor the cat's excretion in real time and automatically filter and store contaminated litter pellets after use, reducing the frequency of manual cleaning. This smart device not only improves the hygiene of the cat's living environment but also saves owners a significant amount of time and effort. However, while existing smart litter boxes can effectively store contaminated litter pellets, they cannot perform thorough cleaning. When the accumulated contaminated litter pellets reach a certain level, owners still need to manually clean them periodically to maintain the cleanliness and hygiene of the smart litter box. This process inevitably brings some trouble and inconvenience to busy owners, especially when the cat uses the litter box frequently, as the accumulated contaminated litter pellets increase rapidly, making cleaning more tedious and further increasing the burden of manual cleaning. Utility Model Content

[0003] In view of this, this utility model proposes an intelligent cat litter box, which aims to solve the problem that existing intelligent cat litter boxes cannot thoroughly clean up contaminated cat litter particles and still require owners to clean them manually on a regular basis.

[0004] This utility model proposes an intelligent cat litter box, including a control circuit, a litter cavity, a first bracket, a base, and support feet; wherein,

[0005] A partition is provided inside the pelvic cavity. The partition has a hollow structure for filtering contaminated cat litter particles. The partition divides the internal space of the pelvic cavity into a storage area for retaining clean cat litter particles and a filtering area for retaining contaminated cat litter particles. Synchronous gears are provided on the outer wall of the pelvic cavity.

[0006] One end of the first bracket is movably connected to the outer wall of the pelvic cavity, and the other end of the first bracket is connected to the top of the base. The first bracket is equipped with a first motor and a drive gear. The drive gear is sleeved on the output shaft end of the first motor and meshes with the synchronous gear.

[0007] The control circuit is installed inside the base and is electrically connected to the first motor. The base has a hollow structure and the pelvic cavity portion passes through the hollow area of ​​the hollow structure.

[0008] The support leg is connected to the bottom of the base, and the height of the support leg is greater than the height of the external toilet or squatting pan.

[0009] The first motor can drive the pelvis to rotate to a position that does not obstruct the hollow area through the meshing motion of the drive gear and the synchronous gear, so as to open the litter drop channel. The contaminated cat litter particles filtered by the hollow structure pass through the litter drop channel to the toilet or squat toilet, while clean cat litter particles pass through the hollow structure and stay in the storage area. The litter drop channel consists of the opening of the pelvis, the hollow area, and the opening of the toilet or squat toilet.

[0010] In one possible implementation, the partition includes an integrally formed baffle and the hollow structure;

[0011] The baffle is located above the partition and is connected above the pelvic cavity to form the storage area;

[0012] The perforated structure is located below the partition and is separated from the pelvic cavity. The aperture of the perforated structure is larger than the size of clean cat litter particles and smaller than the size of soiled cat litter particles.

[0013] In one possible implementation, the smart litter box further includes a second support, which has the same shape as the first support and is located on the left and right sides of the litter cavity respectively. One end of the second support is movably connected to the outer wall of the litter cavity, and the other end of the second support is connected to the top of the base.

[0014] In one possible implementation, the pelvis is a spherical crown-shaped structure larger than a hemisphere with its opening facing forward, the base is a hollow square structure, and the bottom of the pelvis passes through the hollow area of ​​the hollow square structure.

[0015] In one possible implementation, the smart litter box further includes four gravity sensors, each of which is electrically connected to the control circuit, and the four gravity sensors are located at the four corners of the hollow square structure.

[0016] In one possible implementation, the support leg includes four retractable columns, the tops of which are respectively connected to the four corners of the hollow square structure.

[0017] In one possible implementation, the smart litter box also includes four casters, each of which corresponds to a column and is detachably connected by threads.

[0018] In one possible implementation, the smart litter box further includes a first wireless communication module, a thermal sensor, and an infrared sensor. The first wireless communication module, the thermal sensor, and the infrared sensor are all electrically connected to the control circuit. The first wireless communication module is disposed inside the base. The thermal emitting part and the thermal receiving part of the thermal sensor are respectively located on the left and right sides of the inner wall of the pelvis and are arranged opposite to each other. The infrared emitting part and the infrared receiving part of the infrared sensor are respectively located on the left and right sides of the inner wall of the pelvis and are arranged opposite to each other.

[0019] In one possible implementation, the smart litter box further includes a flushing component, which includes a second wireless communication module and a flushing structure, wherein the second wireless communication module is electrically connected to the first wireless communication module.

[0020] The flushing structure includes a second motor, a transmission gear, and a rack. The transmission gear is sleeved on the output shaft end of the second motor and meshes with the gear teeth on the rack. The second motor can drive the rack to move up and down through the meshing motion of the transmission gear and the gear teeth, so that the water valve switch of the toilet or squat toilet located below the rack can be lowered or raised.

[0021] In one possible implementation, the smart litter box further includes an energy storage battery disposed inside the base and electrically connected to the control circuit.

[0022] Compared with existing technologies, the advantages of this utility model are as follows: A smart litter box includes a control circuit, a litter cavity, a first support, a base, and supporting feet; wherein, a partition is provided inside the litter cavity, the partition has a hollow structure for filtering contaminated litter particles, and a synchronous gear is provided on the outer wall of the litter cavity; a first motor and a drive gear are provided inside the first support; the base is a hollow structure, and part of the litter cavity passes through the hollow area of ​​the hollow structure; the height of the supporting feet is greater than the height of the external toilet or squat toilet; the first motor can drive the litter cavity to a position that does not obstruct the hollow area through the meshing motion of the drive gear and the synchronous gear, so as to open the litter drop channel, and the contaminated litter particles filtered by the hollow structure pass through the litter drop channel to the toilet or squat toilet, while clean litter particles pass through the hollow structure and stay in the storage area; wherein, the litter drop channel is composed of the opening of the litter cavity, the hollow area, and the opening of the toilet or squat toilet. Therefore, with the support feet, this smart litter box can be stably placed above the external toilet or squat toilet. After the first motor is activated, it rotates the litter box, and the baffles inside the box also rotate. The rotating baffles effectively filter contaminated litter particles, while allowing clean litter particles to pass through the perforated structure and remain in the storage area. In its initial state, the litter box is positioned within the hollow area of ​​the base, blocking the toilet or squat toilet and thus obstructing the litter drop channel. When the litter box rotates, its overall position rises, no longer obstructing the toilet or squat toilet, thus opening the litter drop channel. This rotation allows contaminated litter particles to fall smoothly from the opening of the litter box under the influence of gravity, passing through the hollow area of ​​the base and the opening of the toilet or squat toilet, ultimately falling into the toilet or squat toilet. This achieves the goal of thoroughly cleaning contaminated litter particles from the smart litter box, eliminating the need for regular manual cleaning by the owner. This design not only improves litter cleaning efficiency and reduces the burden on owners but also ensures a more comfortable and hygienic user experience for cats. Attached Figure Description

[0043] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] Please refer to Figure 1-11 As shown, this utility model proposes an intelligent cat litter box, including a control circuit, a litter cavity 10, a first bracket 20, a base 30, and support feet 40; wherein,

[0045] A partition 11 is provided inside the pelvic cavity 10. The partition 11 has a hollow structure 111 for filtering contaminated cat litter particles. The partition 11 divides the internal space of the pelvic cavity 10 into a storage area 12 for retaining clean cat litter particles and a filtering area 13 for retaining contaminated cat litter particles. A synchronous gear 14 is provided on the outer wall of the pelvic cavity 10.

[0046] One end of the first bracket 20 is movably connected to the outer wall of the pelvic cavity 10, and the other end of the first bracket 20 is connected to the top of the base 30. The first bracket 20 is provided with a first motor 21 and a drive gear 22 inside. The drive gear 22 is sleeved on the output shaft end of the first motor 21 and meshes with the synchronous gear 14.

[0047] The control circuit is installed inside the base 30. The control circuit is electrically connected to the first motor 21. The base 30 is a hollow structure. The pelvic cavity 10 is partially inserted into the hollow area of ​​the hollow structure.

[0048] The support leg 40 is connected to the bottom of the base 30, and the height of the support leg 40 is greater than the height of the external toilet or squatting pan.

[0049] The first motor 21 can drive the pelvic cavity 10 to rotate to a position that does not obstruct the hollow area through the meshing motion of the drive gear 22 and the synchronous gear 14, so as to open the litter drop channel. The contaminated cat litter particles filtered by the hollow structure 111 pass through the litter drop channel to the toilet or squat toilet, while clean cat litter particles pass through the hollow structure 111 and stay in the storage area 12. The litter drop channel is composed of the opening of the pelvic cavity 10, the hollow area, and the opening of the toilet or squat toilet.

[0050] Specifically, this smart litter box allows users to place it directly on the toilet or squat toilet when needed, requiring no additional installation steps for immediate use. When not in use, users can easily remove the smart litter box from the toilet or squat toilet, saving space. This is especially important for residents of small apartments or homes with limited space, as users can flexibly adjust the position of the smart litter box as needed. Furthermore, the support feet 40 are higher than the external height of the toilet or squat toilet, ensuring effective alignment of the smart litter box during use. Simultaneously, the base 30 features a hollow structure, with the litter cavity 10 partially passing through the hollow area of ​​this structure. This design not only reduces the overall weight of the product but also makes the smart litter box more stable during use, eliminating concerns about tilting or instability.

[0051] Compared to existing technologies, the intelligent litter box proposed in this embodiment can be stably placed above an external toilet or squat toilet using the support feet 40. After starting the first motor 21, the motor 21 drives the litter box 10 to rotate, and simultaneously the partition 11 inside the litter box 10 rotates accordingly. The rotating partition 11 effectively filters contaminated litter particles within the litter box 10, while allowing clean litter particles to pass through the hollow structure 111 and remain in the storage area 12. In the initial state of the intelligent litter box, the litter box 10 is inserted into the hollow area of ​​the base 30 and blocks the toilet or squat toilet, thus blocking the litter discharge channel. When the litter box 10 rotates, its overall position rises and it no longer blocks the toilet or squat toilet, thereby opening the litter discharge channel. This rotating motion allows contaminated litter granules to fall smoothly from the opening of the litter box 10 under the influence of gravity, and then through the hollow area of ​​the base 30 and the opening of the toilet or squat toilet, ultimately falling into the toilet or squat toilet. This achieves the goal of thoroughly cleaning contaminated litter granules from the smart litter box, eliminating the need for regular manual cleaning by the owner. This design not only improves the efficiency of litter cleaning and reduces the burden on the owner, but also ensures a more comfortable and hygienic user experience for the cat.

[0052] In some embodiments of this application, the partition 11 includes an integrally formed baffle 112 and the hollow structure 111;

[0053] The baffle 112 is located above the partition 11, and the baffle 112 is connected above the pelvic cavity 10 to form the storage area 12;

[0054] The perforated structure 111 is located below the partition 11 and is separated from the pelvic cavity 10. The aperture of the perforated structure 111 is larger than the size of clean cat litter particles and smaller than the size of contaminated cat litter particles.

[0055] For details, please refer to Figure 2-5 As shown, the baffle 112 is a continuous structure connected above the partition 11. The baffle 112 and the inner wall above the pelvic cavity 10 enclose a storage area 12 with an opening. The hollow structure 111 is separate from the pelvic cavity 10, meaning there is a gap between the edge of the hollow structure 111 and the inner wall of the pelvic cavity 10. The opening of the storage area 12 communicates with this gap. The width of this gap is greater than the width of the clean cat litter granules and less than the width of the soiled cat litter granules. This design allows clean cat litter granules to quickly fall back to the initial position of the pelvic cavity 10 through the gap when the first motor 21 drives the pelvic cavity 10 to rotate and return to its initial state through the hollow area of ​​the base 30, for use next time. Compared to allowing clean litter granules to reset directly through the perforated structure 111, this separate reset method not only improves the efficiency of clean litter granule reset but also speeds up the reset process, effectively avoiding the retention or blockage that might occur with direct reset through the perforated structure 111. Furthermore, this design effectively reduces litter waste, ensuring that the number of clean litter granules in the pelvic cavity 10 remains at an optimal level each time it is used, thereby improving litter utilization and lifespan. It should be noted that users typically place litter at the bottom of the pelvic cavity 10. That is, the initial position of the clean litter granules is at the bottom of the pelvic cavity 10. Because the volume of clean litter granules increases upon contact with liquid, setting the aperture size of the perforated structure 111 to be larger than the size of the clean litter granules but smaller than the size of the contaminated litter granules allows the perforated structure 111 to scoop up the litter at the bottom of the pelvic cavity 10 and filter out the contaminated litter granules when the pelvic cavity 10 rotates.

[0056] In some embodiments of this application, the smart litter box further includes a second support 50, which has the same shape as the first support 20 and is disposed on the left and right sides of the pelvic cavity 10 respectively. One end of the second support 50 is movably connected to the outer wall of the pelvic cavity 10, and the other end of the second support 50 is connected to the top of the base 30.

[0057] For details, please refer to Figure 6-8As shown, the first bracket 20 and the second bracket 50 are identical in shape and located on the left and right sides of the pelvic cavity 10, forming a symmetrical structure. This symmetrical design effectively distributes the weight of the pelvic cavity 10, ensuring that the smart litter box remains balanced during use and preventing the pelvic cavity 10 from tilting or becoming unstable. Furthermore, the two brackets can evenly bear the force generated when the pelvic cavity 10 rotates, reducing wobbling caused by rotation and ensuring smoothness and stability during rotation. It should be noted that both the first bracket 20 and the second bracket 50 can float up and down 1-2 mm relative to the base 30, allowing the gravity sensor 31 mounted on the base 30 to more effectively sense changes in gravity and improve detection accuracy. Moreover, the outer shells of both the first bracket 20 and the second bracket 50 consist of an upper shell and a lower shell, which are detachably connected to facilitate maintenance of the internal components of the first bracket 20 and the second bracket 50.

[0058] In some embodiments of this application, the pelvic cavity 10 is a spherical crown-shaped structure larger than a hemisphere and with its opening facing forward, the base 30 is a hollow square structure, and the bottom of the pelvic cavity 10 passes through the hollow area of ​​the hollow square structure.

[0059] Specifically, the forward-facing opening of the pelvis 10 makes it easier for cats to enter and exit. The dome-shaped structure, larger than a hemisphere, effectively reduces litter spillage during use, preventing litter from scattering outside and maintaining a clean environment. Cats typically prefer enclosed or semi-enclosed spaces, and the dome-shaped structure provides a relatively safe and comfortable environment, allowing cats to relax more during use. The square base 30 provides stable support for the pelvis 10, ensuring it won't tilt or wobble during use, enhancing overall stability. Furthermore, the combination of the dome and square shapes creates a unique aesthetic, enhancing the overall beauty of the home.

[0060] In some embodiments of this application, the smart litter box further includes four gravity sensors 31, each of which is electrically connected to the control circuit, and the four gravity sensors 31 are located at the four corners of the hollow square structure.

[0061] For details, please refer to Figure 9 As shown, four gravity sensors 31 are located at the four corners of the hollow square structure, enabling more even monitoring of gravity changes throughout the pelvic cavity 10. This evenly distributed design accurately detects whether the cat is inside the pelvic cavity 10. When the cat enters or leaves the pelvic cavity 10, the gravity sensors 31 sense the change in gravity, thus determining the cat's position. This function helps the smart litter box automatically initiate the litter cleaning program after the cat uses the litter, thereby improving the product's automation level.

[0062] In some embodiments of this application, the support foot 40 includes four retractable columns, the tops of which are respectively connected to the four corners of the hollow square structure.

[0063] Specifically, different cats have different usage habits and preferences, especially older or less mobile cats. The retractable support legs 40 can be adjusted in height according to the cat's needs, providing a more comfortable usage height and encouraging the cat to use the smart litter box more readily. Furthermore, the retractable support legs 40 can be adjusted to accommodate the height of different sanitary facilities, allowing the smart litter box to be placed stably on toilets or squat toilets. This flexibility ensures the product can adapt to various home environments and meet the needs of different users. By adjusting the height of each column, the smart litter box can also remain stable on uneven or tilted surfaces. This stability is crucial for the cat's user experience, effectively preventing the litter box 10 from tilting or wobbling, ensuring the cat's sense of security during use. In addition, the four-column support design further enhances the smart litter box's anti-tipping ability, especially when the cat is entering or exiting the litter box 10, effectively preventing tilting or tipping due to sudden movements, while also avoiding deformation or damage caused by excessive localized stress. Furthermore, placing the four pillars at the four corners of the hollow square structure effectively lowers the overall center of gravity, improving the product's stability. This design also results in a cleaner and more aesthetically pleasing appearance for the smart litter box, avoiding the cluttered look of the supporting structure and enhancing the product's visual appeal.

[0064] In some embodiments of this application, the smart litter box further includes four casters, each of which corresponds to a column and is detachably connected by threads.

[0065] Specifically, the addition of omnidirectional wheels makes moving the smart litter box incredibly convenient. Users don't need to lift it; a simple push is all it takes to reposition the litter box, greatly enhancing the user experience. The omnidirectional wheels allow users to easily push the smart litter box to the toilet or squat toilet, ensuring it's readily available when needed, thus improving the cat's experience. When not in use, the smart litter box can be easily pushed aside, avoiding taking up space around the toilet or squat toilet.

[0066] In some embodiments of this application, the smart litter box further includes a first wireless communication module, a thermal sensor, and an infrared sensor. The first wireless communication module, the thermal sensor, and the infrared sensor are all electrically connected to the control circuit. The first wireless communication module is disposed inside the base 30. The thermal emitting part and the thermal receiving part of the thermal sensor are respectively located on the left and right sides of the inner wall of the pelvic cavity 10 and are arranged opposite to each other. The infrared emitting part and the infrared receiving part of the infrared sensor are respectively located on the left and right sides of the inner wall of the pelvic cavity 10 and are arranged opposite to each other.

[0067] Specifically, the infrared sensor can monitor the cat's behavior of entering and exiting the pelvic cavity 10 in real time. When the cat approaches or enters the pelvic cavity 10, the infrared sensor immediately detects this action. This function provides data support for the subsequent intelligent control of the smart litter box. The control circuit is connected to both the infrared sensor and the first wireless communication module, and can transmit control signals converted from the cat's behavior information detected by the infrared sensor. This allows modules receiving these control signals to start or stop corresponding functions, such as the smart litter box's soiled litter particle cleaning program or adjusting the working mode, ensuring that the smart litter box can intelligently respond according to the cat's usage. By combining the infrared sensor with the first wireless communication module, the smart litter box can achieve more efficient intelligent management.

[0068] Specifically, the thermal sensor can monitor temperature changes within the pelvic cavity 10 in real time, helping to determine whether a cat has entered the pelvic cavity 10. Adding a thermal sensor inside the pelvic cavity 10 further compensates for the blind spots of the infrared sensor, thereby improving the overall accuracy and reliability of the detection. Moreover, if the infrared sensor malfunctions, the thermal sensor can still continue to operate, and vice versa. This dual detection mechanism ensures effective monitoring of the cat's activity within the pelvic cavity 10 under any circumstances, enhancing the responsiveness and sensitivity of the smart litter box. Furthermore, the infrared sensor and thermal sensor can be directly installed inside the pelvic cavity 10, or they can be positioned relative to the first support 20 and the second support 50, with detection light being introduced into the pelvic cavity 10 through openings. The specific installation method can be determined based on actual application requirements, monitoring accuracy requirements, and the structural design of the pelvic cavity 10, ensuring that both the infrared sensor and the thermal sensor can effectively capture the cat's activity information, improving the overall monitoring performance and reliability.

[0069] In some embodiments of this application, the smart litter box further includes a flushing component 60, which includes a second wireless communication module and a flushing structure, wherein the second wireless communication module is electrically connected to the first wireless communication module;

[0070] The flushing structure includes a second motor 61, a transmission gear 62, and a rack 63. The transmission gear 62 is sleeved on the output shaft end of the second motor 61 and meshes with the gear teeth on the rack 63. The second motor 61 can drive the rack 63 to move up and down through the meshing motion of the transmission gear 62 and the gear teeth, so that the water valve switch of the toilet or squat toilet located below the rack 63 can be lowered or raised.

[0071] For details, please refer to Figure 10 As shown, the second wireless communication module is electrically connected to the first wireless communication module, meaning that the two modules can transmit data and communicate wirelessly. For example, after the cat finishes using the smart litter box, the second wireless communication module receives a control signal from the first wireless communication module and starts the second motor 61 to drive the transmission gear 62 and rack 63. The up-and-down movement of the rack 63 directly affects the water valve switch of the toilet or squat toilet located below it. By controlling the up-and-down movement of the rack 63, the water valve switch can be opened or closed, thereby completing the automatic flushing function and thoroughly cleaning up the soiled cat litter particles that have fallen into the toilet or squat toilet. Furthermore, the flushing assembly 60 can also be equipped with an infrared sensor. When the user's hand waves in front of the infrared sensor, the flushing assembly 60 can be immediately activated to perform the flushing action. This design is particularly suitable for situations where the owner finds that soiled cat litter particles have not been flushed away and a second flush is needed, providing a more convenient user experience.

[0072] In some embodiments of this application, the smart litter box further includes an energy storage battery 32, which is disposed inside the base 30 and electrically connected to the control circuit.

[0073] Specifically, the energy storage battery 32 serves as the power source for the smart litter box, providing necessary power to various components such as the control circuit, wireless communication module, infrared sensor, gravity sensor 31, and flushing assembly 60, ensuring the normal operation of the smart litter box under various working conditions. The energy storage battery 32 is preferably an 18650 type battery. The 18650 type battery is a common lithium-ion battery with a diameter of 18 mm and a length of 65 mm. The 18650 type battery has a high energy density, providing a longer operating time, and is rechargeable, making it suitable for multiple charge-discharge cycles.

[0074] Please refer to Figure 11As shown, the intelligent litter box provided in this embodiment has a main body (including a control circuit, a litter box 10, a first bracket 20, a base 30, and support feet 40) placed on a toilet or squat toilet. The flushing assembly 60 is placed on the water tank of the toilet or squat toilet, directly opposite the water valve switch. When a cat enters the litter box 10, the gravity sensor 31 in the base 30 senses the weight change and activates the infrared sensor to further confirm whether the cat has defecated. Once confirmed, the infrared sensor detects that the cat has left and activates the first motor 21 to rotate the litter box 10. The rotation of the litter box 10 can block contaminated litter particles (including clumps of litter) outside the partition 11 (clean litter particles enter the storage area 12 through the perforated structure 111) and pour them into the toilet or squat toilet through the litter drop channel. Then, the flushing assembly 60 is activated, and the second motor 61 drives the rack 63 to move upward to press the water valve switch and perform the flushing action. In summary, this smart litter box can automatically flush away contaminated litter particles that combine cat urine and feces into the toilet or squat toilet.

[0075] It should be noted that the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0076] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
