Description

Technical Field

[0001] This invention relates to the field of pet supplies technology, and in particular to a particle repositioning structure for a pet excrement screening device. Background Technology

[0002] Cat litter is an object used by owners to bury feces and urine in their cats. It has good absorbency and is usually used in conjunction with a litter box (or cat toilet). An appropriate amount of cat litter is poured into the litter box, and a trained cat will go into the litter box to defecate when it needs to.

[0003] The most important advancement in cat culture is the role of cat litter. Early cat litter was mainly non-clumping, primarily for collecting cat waste. However, with the continuous advancement of cat litter technology, people have gone beyond simply collecting waste, leading to the emergence of clumping litter, such as wood litter, crystal litter, and bentonite litter. These types of litter clump together when exposed to water. Due to the variety of cat litter types, we will refer to them as granular litter here.

[0004] In recent years, smart pet toilets that automatically handle pet waste have become increasingly popular among pet owners. For example, smart cat toilets typically include a chamber for cats to enter and defecate. This chamber is lined with granules that clump together after the cat defecates. The entire chamber is usually rotated to clean these clumps, and an internal screen separates them during this process. However, if the smart cat toilet's sensors malfunction, it may fail to correctly identify whether the cat is inside the chamber. If the cat is still inside and the smart cat toilet activates the automatic cleaning function, it will rotate the cat along with it, potentially causing injury or even death.

[0005] To address the aforementioned issues, the inventors developed a pet excrement sieving device, which includes a housing with a receiving cavity. A conveyor belt for laying particles is installed within the receiving cavity, and a partition with sieve holes is positioned below the conveyor belt. The operation of the conveyor belt causes unconsolidated particles to pass through the sieve holes and fall onto the partition, while consolidated particles fall to the bottom of the receiving cavity for collection. However, the unconsolidated particles falling onto the partition are difficult to recover. After multiple filtrations, particles accumulate on the partition, causing sieve blockage and preventing further filtration. The pet excrement sieving device needs to be disassembled and the accumulated particles removed before it can be used again. Therefore, the inventors believe that a particle repositioning structure is urgently needed to solve this problem. Summary of the Invention

[0006] The main objective of this invention is to provide a particulate matter repositioning structure for a pet excrement screening device, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention proposes a particulate matter resetting structure for a pet excrement screening device, comprising a housing, wherein the housing has an internal receiving cavity, and a first inlet / outlet communicating with the receiving cavity is provided on one side of the housing.

[0008] A first conveyor belt is disposed in the receiving cavity, and particulate matter can be laid on the belt body of the first conveyor belt;

[0009] A partition is positioned within the receiving cavity below the first conveyor belt. The front end of the partition is bent towards the front end of the first conveyor belt to form an inclined section. This inclined section has multiple first screen holes through which particles can pass. The operation of the first conveyor belt causes particles to fall onto the inclined section, allowing unconsolidated particles to pass through the first screen holes.

[0010] The second conveyor belt is located in the receiving cavity between the first conveyor belt and the partition. The front end of the second conveyor belt is located below the inclined part, and the rear end of the second conveyor belt is bent to surround a part of the rear end of the first conveyor belt. The belt body of the second conveyor belt is provided with multiple baffles at intervals. Particles that pass through the first screen holes can fall onto the belt body of the second conveyor belt. Through the operation of the second conveyor belt and the baffles, the particles move upward towards the rear end of the first conveyor belt and automatically fall onto the first conveyor belt during the movement.

[0011] Multiple secondary sieve holes are distributed at the rear end of the partition plate to allow particles to pass through;

[0012] The rear end of the second conveyor belt is inclined toward the front end of the first conveyor belt;

[0013] A storage box is provided below the partition in the receiving cavity, and clumps of particles can be dropped into the storage box along the slope.

[0014] Preferably, the shell has a second inlet / outlet corresponding to the position of the storage box, through which the storage box can enter or exit the receiving cavity.

[0015] Preferably, the first conveyor belt and the second conveyor belt can operate synchronously or independently.

[0016] Preferably, the receiving cavity is provided with a first shielding member at a position above the inclined portion to shield the inclined portion.

[0017] Preferably, the first shielding member and the receiving cavity are integrally formed or are detachably connected. When they are detachably connected, the first shielding member is locked in the receiving cavity by screws or fixed in the receiving cavity by a first snap-fit ​​structure.

[0018] Preferably, the receiving cavity is provided with a second shielding member at a position above the rear end of the second conveyor belt to shield the rear end of the second conveyor belt.

[0019] Preferably, the second shielding member and the receiving cavity are integrally formed or are detachably connected. When they are detachably connected, the second shielding member is locked in the receiving cavity by screws or by a second snap-fit ​​structure.

[0020] The present invention provides a first conveyor belt for laying particulate matter within the housing cavity. A partition is positioned below the first conveyor belt, with its front end bent to form an inclined section facing the front end of the first conveyor belt. Multiple first sieve holes for filtering particulate matter are provided on the inclined section. A second conveyor belt is positioned between the first conveyor belt and the partition, with its front end located below the inclined section and its rear end bent to partially surround the rear end of the first conveyor belt. Multiple baffles are spaced along the belt body of the second conveyor belt. A pet cat can enter the housing cavity through the first inlet / outlet to defecate. The movement of the first conveyor belt causes the particulate matter laid on it to fall onto the inclined section. Unclumped particulate matter can pass directly through the first conveyor belt. After passing through the sieve holes, the particles fall onto the second conveyor belt. Agglomerated particles then fall along the inclined path below the partition to await collection, thus achieving particle sieving. Particles falling onto the second conveyor belt can be moved to the top of the first conveyor belt by the baffles, and automatically fall back onto the first conveyor belt during this movement, achieving automatic particle resetting. Compared to traditional methods, this invention achieves particle filtration and sieving by horizontally conveying particles through the first conveyor belt and using the first sieve holes, while automatically resetting the particles via the second conveyor belt. This solves the problem of particle accumulation, eliminating the need to disassemble the sieving device to clean up accumulated particles, effectively avoiding clogging of the first sieve holes, and allowing for the recycling of sieved particles, thus preventing waste.

[0028] This invention proposes a particle repositioning structure for a pet excrement screening device.

[0029] In embodiments of the present invention, such as Figures 1 to 4 As shown, the particulate resetting structure of the pet excrement screening device includes a shell, a first conveyor belt, a partition, and a second conveyor belt.

[0030] The housing 1 has an internal cavity 100, and a first inlet / outlet 11 communicating with the cavity 100 is provided on one side of the housing 1. The first conveyor belt 2 is disposed in the cavity 100, and particles can be laid on the belt body of the first conveyor belt 2. The partition 3 is disposed in the cavity 100 corresponding to the position below the first conveyor belt 2. The front end of the partition 3 is bent towards the front end of the first conveyor belt 2 to form an inclined part 31. The inclined part 31 is distributed with a plurality of first sieve holes 32 that allow particles to pass through. The operation of the first conveyor belt can cause particles to fall onto the inclined part 31 and allow unconsolidated particles to pass through. The particles pass through the first sieve hole 32; the second conveyor belt 4 is located in the receiving cavity 100 between the first conveyor belt 2 and the partition 3. The front end of the second conveyor belt 4 is located below the inclined part 31. The rear end of the second conveyor belt 4 is bent and surrounds part of the rear end of the first conveyor belt 2. The belt body of the second conveyor belt 4 is provided with multiple baffles 41 at intervals. The particles that pass through the first sieve hole 32 can fall onto the belt body of the second conveyor belt 4. Through the operation of the second conveyor belt 4 and the baffles 41, the particles move upward toward the rear end of the first conveyor belt 2 and automatically fall onto the first conveyor belt 2 during the movement.

[0031] The present invention provides a first conveyor belt for laying particulate matter within the housing cavity. A partition is positioned below the first conveyor belt, with its front end bent to form an inclined section facing the front end of the first conveyor belt. Multiple first sieve holes for filtering particulate matter are provided on the inclined section. A second conveyor belt is positioned between the first conveyor belt and the partition, with its front end located below the inclined section and its rear end bent to partially surround the rear end of the first conveyor belt. Multiple baffles are spaced along the belt body of the second conveyor belt. A pet cat can enter the housing cavity through the first inlet / outlet to defecate. The movement of the first conveyor belt causes the particulate matter laid on it to fall onto the inclined section. Unclumped particulate matter can pass directly through the first conveyor belt. After passing through the sieve holes, the particles fall onto the second conveyor belt. Agglomerated particles then fall along the inclined path below the partition to await collection, thus achieving particle sieving. Particles falling onto the second conveyor belt can be moved to the top of the first conveyor belt by the baffles, and automatically fall back onto the first conveyor belt during this movement, achieving automatic particle resetting. Compared to traditional methods, this invention achieves particle filtration and sieving by horizontally conveying particles through the first conveyor belt and using the first sieve holes, while automatically resetting the particles via the second conveyor belt. This solves the problem of particle accumulation, eliminating the need to disassemble the sieving device to clean up accumulated particles, effectively avoiding clogging of the first sieve holes, and allowing for the recycling of sieved particles, thus preventing waste.

[0032] Specifically, a storage box 5 is provided in the cavity 100 below the partition 3, and the clumps of particles can fall into the storage box 5 along the inclined part 31.

[0033] Specifically, the housing 1 is provided with a second inlet / outlet 12 at the position corresponding to the storage box 5, and the storage box 5 can enter or exit the receiving cavity 100 through the second inlet / outlet 12.

[0034] Specifically, the rear end of the partition 3 has multiple second screen holes 33 that allow particles to pass through. The particles can be swept into the second screen holes 33 by the reverse rotation of the second conveyor belt 4 in conjunction with the baffle 41, so that they fall into the storage box 5.

[0035] Specifically, the first conveyor belt 2 and the second conveyor belt 4 can operate synchronously or independently.

[0036] Specifically, the rear end of the second conveyor belt 4 is inclined toward the front end of the first conveyor belt 2 to ensure that the particles can automatically fall onto the rear end of the first conveyor belt 2.

[0037] Specifically, the cavity 100 is provided with a first shielding member 6 above the inclined portion 31 to shield the inclined portion 31.

[0038] Specifically, the first shielding member 6 and the receiving cavity 100 are integrally formed or detachably connected. When they are detachably connected, the first shielding member 6 is locked in the receiving cavity 100 by screws or by a first snap-fit ​​structure.

[0039] Specifically, the receiving cavity 100 is provided with a second shielding member 7 at the position above the rear end of the second conveyor belt 4, which is used to shield the rear end of the second conveyor belt 4.

[0040] Specifically, the second shielding member 7 and the receiving cavity 100 are integrally formed or detachably connected. When they are detachably connected, the second shielding member 7 is locked in the receiving cavity 100 by screws or by a second snap-fit ​​structure.

[0041] Specifically, some of the baffles 41 abut against the belt body of the first conveyor belt 2. Since the first conveyor belt 2 and the second conveyor belt 4 can operate synchronously, the state in which the baffles 41 abut against the belt body of the first conveyor belt 2 does not affect the operation of the first conveyor belt 2 and the second conveyor belt 4, nor does it affect the second conveyor belt 4 from conveying particulate matter. At the same time, the two adjacent baffles 41 cooperate with the partial belt body of the first conveyor belt 2 to form a space that can accommodate particulate matter, so as to better convey particulate matter to the first conveyor belt 2.

[0042] Specifically, the cavity is equipped with a sensor (not shown) and a control system (not shown) electrically connected to the sensor, the first conveyor belt 2 and the second conveyor belt 4. The sensor is used to sense whether the pet cat is in the receiving cavity 100. When it is determined that the pet cat is not in the receiving cavity 100, the control system can drive the first conveyor belt 2 and the second conveyor belt 4 to operate to achieve the function of automatically cleaning particles.

[0043] It is understandable that the first conveyor belt 2 and the second conveyor belt 4 have the same structure, mainly including the belt body, the rotating shaft and the drive motor, which are existing technologies, and their specific structural principles will not be described in detail here.

[0044] It should be noted that the sensor and control system can refer to existing technologies, and their specific structural principles will not be elaborated here.

[0045] Specifically, the housing 1, partition 3, first shield 6, and second shield 7 can be made of plastic, metal, or rubber.

[0046] Specifically, the first entrance / exit 11 is provided with a movable door (not shown), which is movably installed on the housing 1 and can move between the closed and open positions of the first entrance / exit 11.

[0047] Specifically, the shell 1 has a partially transparent structure to facilitate observation of the interior of the cavity from the outside.

[0048] Understandably, if some particles do not fall into the rear end of the first conveyor belt 2 during the conveying process of the second conveyor belt 4, these particles can continue to fall into the rear end of the partition 3 as the second conveyor belt 4 operates, and then fall into the collection box 5 after passing through the second screen hole 33.

[0049] Specifically, the housing 1 is a box structure made of plastic, acrylic, metal or rubber.

[0050] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
