Description

Technical Field

[0001] This utility model relates to the technical field of intelligent cat litter boxes, and more specifically, to an anti-pinch intelligent cat litter box. Background Technology

[0002] Smart litter boxes, as a common product in the current field of smart pet homes, are gradually becoming an important piece of equipment for pet-owning families due to their convenient functions such as automatic cleaning and odor control.

[0003] In existing technologies, smart litter boxes primarily detect the presence of a cat in the litter box by installing a weighing structure at the bottom. This structure detects any increase in weight within the litter box to determine if a cat is inside, preventing injuries or even death to the cat. However, for kittens, due to their small size, this weighing method is insufficient for effective detection. Furthermore, in complex usage environments, changes in the weight of the litter box, such as moisture or the cat knocking litter out of the box, can interfere with the weighing structure's ability to determine the presence of a cat. This can lead to inaccurate results, affecting the normal functioning of the smart litter box and the safety of the cat during use. Utility Model Content

[0004] The purpose of this invention is to provide an anti-pinch smart cat litter box, aiming to solve the problem of insufficient safety of existing smart cat litter boxes.

[0005] This utility model is implemented as follows: an anti-pinch smart cat litter box includes a support base and a litter bin. The support base has upward-protruding baffles on both sides, and an installation area is formed between the two baffles. The litter bin is located in the installation area. The litter bin is rotatably connected to the two baffles on both sides, and has a litter chamber for placing cat litter.

[0006] The support base is equipped with multiple radar sensors, which are arranged facing the outer periphery of the support base. The radar sensors are used to detect whether a cat is approaching around the support base.

[0007] Furthermore, the support base is equipped with a drive motor, which has a rotating shaft. The rotating shaft is connected to the cat litter compartment through a transmission structure. The cat litter compartment is equipped with a partition, which has multiple sieve holes. The partition divides the cat litter compartment into a litter storage area and a feces collection area.

[0008] When the drive motor drives the rotating shaft to rotate, the transmission structure drives the cat litter bin to rotate, and the cat litter in the cat litter chamber enters the litter storage area through the sieve holes. The excrement in the cat litter chamber is blocked by the partition in the feces collection area.

[0009] When the radar sensor detects a cat approaching around the support base, the drive motor immediately stops, and the litter box stops rotating to prevent the cat from being pinched or injured.

[0010] Furthermore, the bottom of the support base is provided with a waste collection chamber, which is arranged vertically opposite to the cat litter box.

[0011] During the rotation of the litter box, the excrement in the collection area falls into the collection box under the action of gravity;

[0012] The litter box has perforations on both sides;

[0013] The baffle has an inner end face facing the litter box. The middle of the inner end face of the baffle has a protrusion facing the installation area. The protrusion passes through a hollow hole and forms an internal end face facing the litter box. A distance sensor is provided in the protrusion. The distance sensor identifies whether there is a cat in the litter box through the internal end face.

[0014] Multiple radar sensors are arranged around the outer periphery of the support.

[0015] Furthermore, the transmission structure includes a small gear and a large gear. The small gear is sleeved on the outer circumference of the rotating shaft. The outer circumference of the small gear meshes with the outer circumference of the large gear. The large gear is movably arranged in a baffle and is fixedly connected to the side of the cat litter bin.

[0016] As the rotating shaft rotates, the small gear rotates synchronously with the rotating shaft and drives the large gear to rotate through meshing, causing the litter box, which is fixedly connected to the large gear, to rotate.

[0017] Furthermore, a distance sensor is provided in the protrusion of one of the baffles, and a camera is provided in the protrusion of the other baffle, through which the litter box can be remotely observed.

[0018] Furthermore, the lower surface of the litter box is provided with two downward-protruding annular ridges, the two annular ridges are arranged concentrically, and an annular area is formed between the two annular ridges. A bristle strip is provided in the annular area, and the lower surface of the bristle strip abuts against the top surface of the support base.

[0019] The top of the waste collection chamber has a top opening, and the bristles are arranged circumferentially along the outer periphery of the top opening.

[0020] Furthermore, the bottom of the waste collection chamber is arranged in a convex shape with its bottom facing downwards.

[0021] Furthermore, the collection chamber has a collection cavity, the bottom of which has two symmetrically arranged inclined surfaces. Along the middle of the collection cavity towards both sides of the collection cavity, the inclined surfaces extend downwards at an angle. A central protrusion is provided between the two inclined surfaces, and the central protrusion separates the two inclined surfaces.

[0022] Furthermore, the bottom of the support base is provided with multiple support feet, which are arranged around the outer periphery of the support base.

[0023] Furthermore, a sand-falling pedal is connected to the front side of the support base. The sand-falling pedal has a sand-falling cavity, and a sand-draining plate is provided at the top of the sand-falling cavity. The sand-draining plate has multiple sand-draining holes that communicate with the sand-falling cavity.

[0024] Compared with the prior art, the anti-pinch smart litter box provided by this utility model has multiple radar sensors in the support base, which can detect cats approaching from all sides in advance, effectively preventing the cats from being pinched when the device is running, and greatly improving the safety and reliability of the smart litter box.

[0038] Reference Figure 1-10 The image shown is a preferred embodiment of the present invention.

[0039] The intelligent cat litter box with anti-pinch function provided by this utility model includes a support base 200 and a litter bin 100. The support base 200 has two upwardly protruding baffles 300 on both sides, and the two baffles 300 are spaced apart to form an installation area. The litter bin 100 is provided in the installation area. The two sides of the litter bin 100 are rotatably connected to the two baffles 300 respectively. The litter bin 100 has a litter cavity for placing cat litter.

[0040] The support base 200 is equipped with multiple radar sensors 230, which are arranged in the direction of the outer periphery of the support base 200. The radar sensors 230 are used to detect whether there are cats approaching around the support base 200.

[0041] The aforementioned anti-pinch smart litter box features multiple radar sensors 230 around the support base 200, which can detect approaching cats in advance. Combined with the distance sensor 320 inside the litter chamber, it forms a double protection, covering the entire process of the cat entering, using, and leaving the litter box. This effectively prevents the cat from being pinched during operation and significantly improves the safety and reliability of the smart litter box.

[0042] In this embodiment, the radar sensor 230 is a millimeter-wave radar sensor 230.

[0043] The support base 200 is equipped with a drive motor 240, which has a rotating shaft. The rotating shaft is connected to the cat litter chamber 100 through a transmission structure. The cat litter chamber is equipped with a partition 110, which has multiple sieve holes. The partition 110 divides the cat litter chamber into a litter storage area 112 and a feces collection area 111.

[0044] When the drive motor 240 drives the rotating shaft to rotate, the transmission structure drives the litter bin 100 to rotate. The litter in the litter chamber enters the litter storage area 112 through the sieve holes, while the excrement in the litter chamber is blocked by the partition 110 in the waste collection area 111. In this way, by setting the drive motor 240 on the support base 200, which drives the litter bin 100 to rotate through the transmission structure, and in conjunction with the partition 110 with sieve holes in the litter chamber, the litter and excrement are separated. This solves the problems of tedious manual cleaning and litter waste. The litter can be reused in the litter storage area 112 through the sieve holes, and the excrement is contained in the waste collection area 111. Furthermore, it can be combined with a sensor protection system to achieve automated cleaning while ensuring the safety of the cat, thus improving the practicality of the equipment.

[0045] When the radar sensor 230 detects a cat approaching around the support base 200, the drive motor 240 immediately stops, and the litter box 100 stops rotating to prevent the cat from being pinched.

[0046] The cat litter box 100 has perforated holes 101 on both sides;

[0047] The baffle 300 has an inner end face facing the litter box 100. The middle part of the inner end face has a boss 310 protruding towards the installation area. The boss 310 passes through the hollow hole 101, and the side of the boss 310 facing the litter box forms an inner end face 311. A distance sensor 320 is provided in the boss 310. The distance sensor 320 identifies whether there is a cat in the litter box through the inner end face 311.

[0048] Multiple radar sensors 230 are arranged around the outer periphery of the support base 200 to achieve 360-degree all-round detection of the litter box, resulting in better performance.

[0049] By embedding the boss 310 into the hollow hole 101, and the boss 310 is equipped with a distance sensor 320, the presence of a cat in the litter box can be directly detected. This avoids the problem of the weighing method failing to detect kittens and small cats. At the same time, this design is not affected by changes in the weight of the litter, avoiding misjudgments caused by changes in the state of the litter, and improving the stability of the detection.

[0050] Furthermore, the TOF sensor 320 can detect the remaining cat litter level; when the litter height falls below the set height, the TOF sensor detects insufficient litter and alerts the user. The alert can be sent via an indicator light or a notification from a mobile app.

[0051] In this embodiment, the distance sensor 320 is a TOF distance sensor 320.

[0052] Specifically, the bottom of the support base 200 is provided with a waste collection chamber 400, which is arranged vertically opposite to the cat litter box 100.

[0053] As the litter bin 100 rotates, the excrement in the collection area 111 falls into the collection bin 400 under the influence of gravity. This, combined with the litter waste separation structure, further simplifies the cleaning process and reduces manual operation by the user.

[0054] In this embodiment, the transmission structure includes a small gear 241 and a large gear 330. The small gear 241 is sleeved on the outer periphery of the rotating shaft. The outer periphery of the small gear 241 meshes with the outer periphery of the large gear 330. The large gear 330 is movably arranged in a baffle 300 and is fixedly connected to the side of the cat litter box 100.

[0055] As the rotating shaft rotates, the pinion 241 rotates synchronously with the shaft and, through meshing, drives the large gear 330 to rotate, causing the litter bin 100, which is fixedly connected to the large gear 330, to rotate. This gear transmission method provides stable transmission, low power loss, and precise control of the litter bin 100's rotation speed. It avoids excessively high speeds that could cause litter to splash or excessively low speeds that could affect the separation effect, providing reliable power support for the efficient separation of litter and excrement.

[0056] In this embodiment, a distance sensor 320 is provided in the protrusion 310 of one baffle 300, and a camera 340 is provided on the protrusion 310 of the other baffle 300, allowing remote observation of the litter box. In this way, the camera 340 solves the problem of users being unable to remotely check the status of the litter box, allowing users to periodically observe their cat's behavior in the litter box while traveling.

[0057] The lower surface of the cat litter box 100 is provided with two downward-protruding annular ridges 120. The two annular ridges 120 are arranged concentrically, and an annular area 121 is formed between the two annular ridges 120. A bristle strip is provided in the annular area 121, and the lower surface of the bristle strip abuts against the top surface of the support base 200.

[0058] In a preferred embodiment, the top of the litter box 400 has a top opening, and the bristles are arranged circumferentially along the outer periphery of the top opening. This seals the gap between the litter box 100, the support base 200, and the litter box 400, preventing odors from escaping from the litter box 400, solving the problem of traditional cat odor diffusion, and improving the cleanliness of the usage environment.

[0059] The waste collection chamber 400 is arranged with its bottom facing downwards in a raised shape, which improves space utilization.

[0060] The waste collection chamber 400 has a waste collection cavity, and the bottom of the waste collection cavity has two symmetrically arranged inclined surfaces 401. The inclined surfaces 401 extend downwards along the middle of the waste collection cavity towards both sides of the cavity. A central protrusion 410 is arranged between the two inclined surfaces 401, separating the two inclined surfaces 401. In this way, the design of the central protrusion 410 and the inclined surfaces 401 prevents excrement from accumulating in the middle of the cavity, prevents the top opening of the waste collection chamber 400 from being blocked, and prevents new excrement from falling downwards, so that the excrement is collected on both sides of the central protrusion 410.

[0061] In this embodiment, the bottom of the support base 200 is provided with multiple support feet 210, which are arranged around the outer periphery of the support base 200. In this way, together with the downward protruding design of the waste collection chamber 400, material is saved, space utilization is improved, and the overall stability of the support base 200 is ensured.

[0062] In a preferred embodiment, a litter discharge pedal 220 is connected to the front side of the support base 200. The litter discharge pedal 220 has a litter discharge chamber, and a litter leakage plate 221 is provided at the top of the litter discharge chamber. The litter leakage plate 221 has multiple litter leakage holes communicating with the litter discharge chamber. In this way, when the cat leaves the litter box 100, the litter residue on its paws can fall into the litter discharge chamber through the litter leakage holes, solving the problem of litter being carried out and soiling the environment. Subsequently, the user only needs to clean the litter discharge chamber to recycle the litter, which keeps the environment clean and reduces litter waste.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
