Description

Technical Field

[0001] The invention belongs to the technical field of pet equipment, and in particular relates to an intelligent cat litter box capable of purifying, deodorizing and shoveling feces with high efficiency and a feces shoveling method thereof. Background Art

[0002] With the acceleration of urbanization and the improvement of living standards, the requirements for the environment for raising pets at home are getting higher and higher. As a popular household pet worldwide, cats have their own unique personality. Cats are clean and vigilant animals, and they will bury their excrement after defecation. Nowadays, families who keep cats will first prepare a cat litter box, then train the cat to defecate in it, and manually shovel away the cat feces and clean up the excrement after defecation.

[0003] The existing commonly used cat litter boxes have the following shortcomings: First, cleaning the excrement in the cat litter box is a time-consuming and laborious task. If the cat feces are not cleaned regularly, a pungent odor will be generated, especially in the home, affecting the indoor air and environment; Second, the existing cat litter boxes can only simply solve the problem of cat excretion, and cannot realize the function of intelligent separation and collection of cat feces; Third, the existing cat litter boxes lack the automatic control function of separating cat litter and cat feces, and lack the function of monitoring cat activities and health status; Fourth, when cleaning the cat litter box, the cat litter is often cleaned up together, resulting in a waste of cat litter.

[0004] In view of the above technical problems, the improved cat litter box has the function of automatically collecting cat feces, which can reduce the waste of cat litter in the process of cleaning cat feces, and also has the function of weighing the cat's weight. However, the feces scooping structure of the prior art has the following technical problems in the process of scooping feces: (1) Large particles of feces are not easy to be discharged through the feces scooping structure and are easy to remain in the feces scooping structure and the inner bucket. (2) The cat litter box of the prior art generally has a bad smell after use. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide an intelligent cat litter box and a method for shoveling feces with high efficiency in purification, deodorization and feces shoveling. By optimizing the design of the feces shoveling structure, feces of different sizes can be discharged from the feces outlet through the feces shoveling structure, thereby improving the feces shoveling efficiency; and the intelligent cat litter box can be sterilized and deodorized, with significant effect and being non-toxic and harmless.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An intelligent cat litter box with high efficiency in purification, deodorization and feces scooping includes a box body and an inner barrel rotatably connected to the box body. The prior art uses a motor to drive the inner barrel to rotate clockwise. The front of the inner barrel is provided with a cat inlet and outlet, and the rear of the inner barrel is provided with a feces outlet. The inner barrel is provided with a feces scooping structure, and the feces scooping structure is provided with mesh holes. The mesh holes are designed according to the size of the cat litter so that the cat litter can pass through the mesh holes, but the feces cannot pass through the mesh holes.

[0008] Features:

[0009] In the process of shoveling feces, the present invention makes it difficult for large feces to fall from the feces shoveling structure, and cat litter is easily discharged from the feces outlet along the feces shoveling structure. In view of this technical problem, the present invention makes a specific innovative design for the feces shoveling structure, which includes a separation section and a feces block discharge section, and has a double tilt design for the feces shoveling structure, specifically:

[0010] The mesh is arranged on the separation section, which is inclined downward from the cat inlet and outlet to the feces outlet. The separation section separates cat litter and feces blocks, and the cat litter passes through the mesh and falls into the inner bucket.

[0011] The feces block discharge section is tilted from the separation section to the feces outlet, and the setting height of the feces block discharge section gradually increases from the separation section to the feces outlet. The rear part of the feces block discharge section extends into the feces outlet, so that the feces block discharge section is tilted upward. When the inner barrel rotates clockwise at a certain angle, the setting height of the feces block discharge section is adjusted to gradually decrease from the separation section to the feces outlet. After the rotation of the inner barrel, the feces block discharge section is tilted downward. The feces blocks separated by the separation section gather in the feces block discharge section under the rotation of the inner barrel, and are discharged from the feces outlet along the feces block discharge section. In this way, when the cat litter and feces blocks are separated, the feces block discharge section is tilted upward to reduce the cat litter from the feces outlet; when the inner barrel rotates clockwise at a certain angle, the setting height of the feces block discharge section is adjusted to gradually decrease from the separation section to the feces outlet, so that the feces block discharge section is tilted downward, so that the feces blocks of different sizes have a downward rolling force, which is convenient for quickly discharging the feces blocks of different sizes from the feces outlet, thereby improving the feces shoveling efficiency.

[0012] Through the above-mentioned shit scooping structure, the shit outlet can be set at the central position of the rear part of the inner bucket, and the inner bucket can adapt to various shapes such as square, spherical, cylindrical and elliptical.

[0013] Furthermore, the separation section includes a first plate body, a second plate body and a material stopper, the first plate body is fixedly connected to the front of the inner barrel, the second plate body is connected to the feces discharge section, the meshes are distributed on the first plate body and the second plate body, the meshes on the first plate body separate the cat litter and the feces for the first time, and the meshes on the second plate body separate the cat litter and the feces for the second time. When the inner barrel rotates clockwise, the material stopper blocks the cat litter, so that the cat litter can fall into the inner barrel through the meshes; and the separation section is designed as the first plate body and the second plate body, so that the structure of the separation section can adapt to the structure of the feces discharge section, which is convenient for the later separation section and the feces discharge section to be integrally formed and manufactured, and the contact area and separation time of the separation section with the cat litter and the feces can be increased, thereby improving the separation efficiency of the cat litter and the feces.

[0014] Furthermore, in actual operation, a small portion of the cat litter will still be discharged from the feces outlet along the innovatively designed feces scooping structure of the present invention, resulting in a waste of cat litter. In response to this technical problem, a cat litter blocking portion is provided between the second plate body and the feces block discharge section. The cat litter blocking portion is arranged to be tilted downward from the feces block discharge section toward the second plate body. When the cat litter and feces block are separated, when a small portion of the cat litter rolls from the second plate body toward the feces block discharge section, the cat litter blocking portion blocks and slows down the cat litter, causing the cat litter to roll back onto the second plate body and pass through the mesh holes of the second plate body.

[0015] Furthermore, the mesh holes on the first plate body are arranged toward the second plate body, so that the length direction of the mesh holes on the first plate body is consistent with the direction in which the cat litter rolls on the first plate body, increasing the penetration area of ​​the cat litter on the first plate body, so that the cat litter can quickly pass through the mesh holes on the first plate body. The mesh holes on the second plate body are arranged toward the feces block discharge section, so that the length direction of the mesh holes on the second plate body is consistent with the direction in which the cat litter rolls on the second plate body, increasing the penetration area of ​​the cat litter on the second plate body, so that the cat litter can quickly pass through the mesh holes on the second plate body, and further improving the separation efficiency of cat litter and feces blocks.

[0016] Furthermore, the first plate body is provided with a fixing plate, which is fixed to the front of the inner barrel by fixing screws, and the outer side of the feces discharge section is provided with an outer ring plate, which is fixed to the rear of the inner barrel by fixing screws, so that the feces scooping structure can be detachably connected in the inner barrel, which is convenient for replacing and cleaning the entire feces scooping structure.

[0017] Furthermore, in the prior art, when the amount of cat litter is insufficient, clean cat litter needs to be poured in. At this time, the clean cat litter and the dirty cat litter are mixed together, affecting the use of the cat litter. Therefore, the unused cat litter needs to be discharged from the inner barrel. The operator generally directly shovels the cat litter in the inner barrel with a shovel. The efficiency of shoveling the cat litter is low and the structure of the inner barrel is easily damaged. If the cat litter is discharged by dumping the inner barrel, the structure in the smart cat litter box will fall off, affecting the operation of the smart cat litter box. Therefore, the feces scooping structure of the present invention is provided with an automatic cat litter changing board, which blocks the mesh holes. When the cat litter in the smart cat litter box is insufficient, the user installs the automatic cat litter changing board at the bottom of the feces scooping structure, which blocks the mesh holes on the feces scooping structure, and then controls the inner barrel to rotate in the basin body. At this time, with the coordinated use of the feces scooping structure and the automatic cat litter changing board, the remaining dirty cat litter in the inner barrel falls into the feces collecting bucket through the feces outlet. After the dirty cat litter in the inner barrel is discharged, the clean cat litter is poured back into the inner barrel, thereby achieving the effect of automatic cat litter changing, with high cat litter changing efficiency, without touching the dirty cat litter, and the automatic cat litter changing operation does not affect the subsequent work of the entire smart cat litter box.

[0018] Furthermore, the poop scooping structure is provided with a card block, which is preferably designed at the bottom of the poop scooping structure. The card block can be designed into an L shape and is provided with a card slot. The automatic cat litter changing plate is arranged in the card slot, so that the automatic cat litter changing plate can be quickly installed or disassembled on the poop scooping structure.

[0019] Furthermore, the cat litter that passes through the mesh of the poop scooping structure of the present invention does not return to the gathering center, and the cat litter will be eccentric, which is easy to cause the cat litter to fall from the cat inlet and outlet of the inner bucket to the outside, affecting the external environment. Therefore, a semi-wrapped silicone pad is provided on the inner side of the inner bucket of the present invention, and the silicone pad is provided below the poop scooping structure. The silicone pad gathers the cat litter separated and dropped by the poop scooping structure to the center, so that the cat can enter to defecate next time, reducing the waste of cat litter.

[0020] Generally, the bottom of the silicone pad is close to the cat entrance and exit as the first inclined part, and the bottom of the silicone pad is close to the feces outlet as the second inclined part. The inclination angle of the first inclined part is greater than the inclination angle of the second inclined part. The inclination angle of the second inclined part can be designed to be 3-5 degrees, so that the cat litter gathered on the silicone pad is close to the feces outlet set in the center, so that the feces and cat litter are formed into feces blocks as close to the feces outlet as possible, shortening the rolling distance of the feces blocks on the feces shoveling structure, and further improving the feces shoveling efficiency.

[0021] Furthermore, a restraining piece is provided on the inner side of the inner barrel, which fixes the top edge of the silicone pad on the inner side of the inner barrel. Since the silicone pad is made of soft material, a restraining piece is required to fix it on the inner side of the inner barrel to prevent the silicone pad from shrinking on the inner barrel.

[0022] Furthermore, the basin body includes a bottom shell, a middle frame and a top cover, the middle frame is fixedly connected to the inside of the bottom shell, the inner barrel is arranged in the middle frame, the top cover and the middle frame are detachably connected, the middle frame is provided with a front bracket and a rear bracket, a double-spindle bearing is fixedly connected between the front bracket and the rear bracket, the inner barrel is provided with a connecting shaft, and the connecting shaft is rotatably connected to the double-spindle bearing. The bottom shell is provided with a motor, the motor is provided with a transmission gear, and a gear-like structure is provided on the outer side of the rear portion of the inner barrel, and the transmission gear and the gear-like structure are meshed with each other.

[0023] A method for shoveling feces from an intelligent cat litter box with high efficiency of purification, deodorization and feces shoveling, characterized by comprising the following steps:

[0024] a. Connect the power supply, press and hold the power switch for 3 seconds to turn on the smart cat litter box.

[0025] b. After turning on, the smart cat litter box will automatically perform weighing calibration to facilitate subsequent weighing operations and to understand whether the cat has entered the smart cat litter box.

[0026] c. Put clean cat litter in the inner barrel, and the cat enters the inner barrel through the cat inlet and outlet at the front of the inner barrel to defecate. At this time, automatic weighing is performed to calculate the defecation time. After the cat has defecated or urinated, the feces, urine and cat litter form feces blocks. After the cat has left the smart cat litter box for a period of time, the smart cat litter box is turned on and the smart cat litter box starts to scoop feces blocks. The inner barrel rotates 1-2 circles clockwise in the box body. At this time, the cat litter and feces blocks are deposited in the inner barrel, and the feces scooping structure separates the cat litter and feces blocks while scooping the feces. The separation section of the feces scooping structure separates the cat litter and feces blocks, and the cat litter passes through the mesh and falls into the inner barrel. The feces blocks separated by the separation section are gathered in the feces block discharge section and discharged from the feces block discharge section. The feces blocks fall along the feces block discharge section into the feces collecting bucket at the rear of the smart cat litter box, thereby improving the feces scooping efficiency.

[0027] d. When all the feces have fallen into the collection bucket, continue to control the inner bucket to rotate two full circles in the basin. After the inner bucket returns to its original position, the silicone pad will reduce the centrifugal force deviation of the cat litter in the inner bucket and gather it in the center so that the cat can enter to defecate next time.

[0028] e. When there is no cat, turn on the ozone negative ion generator on the smart cat litter box. The negative ions generated will first precipitate the bacteria in the smart cat litter box, and at the same time release ozone for sterilization and deodorization. Then use a fan to align the air outlet with the cat to deodorize the smart cat litter box again, and then turn on the UV lamp on the smart cat litter box to sterilize the smart cat litter box again, realizing the integration of feces cleaning, sterilization and deodorization, improving the internal cleanliness of the smart cat litter box, and increasing the comfort of the smart cat litter box.

[0029] f. When the alarm on the smart cat litter box detects that there is insufficient cat litter, the alarm is triggered, and the user installs an automatic cat litter changing board at the bottom of the feces scooping structure. The automatic cat litter changing board blocks the mesh holes on the feces scooping structure, and then controls the inner barrel to rotate in the basin body. At this time, with the coordinated use of the feces scooping structure and the automatic cat litter changing board, the remaining dirty cat litter in the inner barrel falls into the feces collection bucket through the feces outlet. When the dirty cat litter in the inner barrel is discharged, the clean cat litter is poured back into the inner barrel, achieving the technical effect of automatic cat litter changing.

[0030] g. Take out the dirty cat litter in the toilet collection bucket, clean and disinfect it, recycle the cat litter, and recycle and reuse the cat litter to reduce the cost of purchasing cat litter.

[0031] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0032] 1. In the process of shoveling feces, the present invention makes it difficult for large particles of feces to fall from the feces shoveling structure, and cat litter is easily discharged from the feces outlet along the feces shoveling structure. In view of this technical problem, the present invention makes a specific innovative design for the feces shoveling structure, which includes a separation section and a feces block discharge section, and has a double tilt design for the feces shoveling structure, specifically:

[0033] The mesh is arranged on the separation section, which is inclined downward from the cat inlet and outlet to the feces outlet. The separation section separates cat litter and feces blocks, and the cat litter passes through the mesh and falls into the inner bucket.

[0034] The feces block discharge section is tilted from the separation section to the feces outlet, and the setting height of the feces block discharge section gradually increases from the separation section to the feces outlet. The rear part of the feces block discharge section extends into the feces outlet, so that the feces block discharge section is tilted upward. When the inner barrel rotates clockwise at a certain angle, the setting height of the feces block discharge section is adjusted to gradually decrease from the separation section to the feces outlet. After the rotation of the inner barrel, the feces block discharge section is tilted downward. The feces blocks separated by the separation section gather in the feces block discharge section under the rotation of the inner barrel, and are discharged from the feces outlet along the feces block discharge section. In this way, when the cat litter and feces blocks are separated, the feces block discharge section is tilted upward to reduce the cat litter from the feces outlet; when the inner barrel rotates clockwise at a certain angle, the setting height of the feces block discharge section is adjusted to gradually decrease from the separation section to the feces outlet, so that the feces block discharge section is tilted downward, so that the feces blocks of different sizes have a downward rolling force, which is convenient for quickly discharging the feces blocks of different sizes from the feces outlet, thereby improving the feces shoveling efficiency.

[0035] 2. In the prior art, when the amount of cat litter is insufficient, clean cat litter needs to be poured in. At this time, the clean cat litter and the dirty cat litter are mixed together, which affects the use of the cat litter. Therefore, it is necessary to discharge the unused cat litter from the inner bucket. The operator generally directly shovels the cat litter in the inner bucket with a shovel. The cat litter shoveling efficiency is low and the structure of the inner bucket is easily damaged. If the cat litter is discharged by dumping the inner bucket, the structure in the smart cat litter box will fall off, affecting the operation of the smart cat litter box. Therefore, the feces scooping structure of the present invention is provided with an automatic cat litter changing board, which blocks the mesh holes. When the cat litter in the smart cat litter box is insufficient, the user installs the automatic cat litter changing board at the bottom of the feces scooping structure, which blocks the mesh holes on the feces scooping structure, and then controls the inner barrel to rotate in the basin body. At this time, with the coordinated use of the feces scooping structure and the automatic cat litter changing board, the remaining dirty cat litter in the inner barrel falls into the feces collecting bucket through the feces outlet. After the dirty cat litter in the inner barrel is discharged, the clean cat litter is poured back into the inner barrel, thereby achieving the effect of automatic cat litter changing, with high cat litter changing efficiency, without touching the dirty cat litter, and the automatic cat litter changing operation does not affect the subsequent work of the entire smart cat litter box.

[0036] 3. The cat litter that passes through the mesh of the poop scooping structure of the present invention does not return to the gathering center, and the cat litter will be eccentric, which is easy to cause the cat litter to fall from the cat inlet and outlet of the inner bucket to the outside, affecting the external environment. Therefore, a semi-wrapped silicone pad is provided on the inner side of the inner bucket of the present invention, and the silicone pad is provided below the poop scooping structure. The silicone pad gathers the cat litter separated and dropped by the poop scooping structure to the center so that the cat can enter to defecate next time, reducing the waste of cat litter.

[0037] Generally, the bottom of the silicone pad is close to the cat entrance and exit as the first inclined part, and the bottom of the silicone pad is close to the feces outlet as the second inclined part. The inclination angle of the first inclined part is greater than the inclination angle of the second inclined part. The inclination angle of the second inclined part can be designed to be 3-5 degrees, so that the cat litter gathered on the silicone pad is close to the feces outlet set in the center, so that the feces and cat litter are formed into feces blocks as close to the feces outlet as possible, shortening the rolling distance of the feces blocks on the feces shoveling structure, and further improving the feces shoveling efficiency.

[0038] 4. The negative ions generated by the ozone negative ion generator of the present invention first precipitate the bacteria in the smart cat litter box, and at the same time release ozone for sterilization and deodorization, and then use a fan to align the air outlet of the cat to deodorize the smart cat litter box again, and then turn on the UV lamp on the smart cat litter box to sterilize the smart cat litter box again. The UV lamp sterilizes cat feces, realizing the integration of feces shoveling, sterilization and deodorization, with significant sterilization and deodorization effects, and is non-toxic and harmless, improving the internal cleanliness of the smart cat litter box and increasing the comfort of the smart cat litter box.

DETAILED DESCRIPTION

[0053] like Figures 1 to 12 As shown, a smart cat litter box with high efficiency in purifying, deodorizing and shoveling feces of the present invention comprises a box body 1 and an inner barrel 2 rotatably connected to the box body 1. The prior art uses a motor to drive the inner barrel 2 to rotate clockwise. A cat inlet and outlet 3 is provided at the front of the inner barrel 2, and a feces outlet 4 is provided at the rear of the inner barrel 2. A feces shoveling structure 5 is provided inside the inner barrel 2, and a mesh 8 is provided in the feces shoveling structure 5. The mesh 8 is designed according to the size of the cat litter so that the cat litter can pass through the mesh 8, but the feces cannot pass through the mesh 8.

[0054] In the process of shoveling feces, the large particles of feces are not easy to fall from the feces shoveling structure 5, and the cat litter is easy to be discharged from the feces outlet 4 along the feces shoveling structure 5. In view of this technical problem, the present invention makes a specific innovative design for the feces shoveling structure 5, which includes a separation section 6 and a feces block discharge section 7. The feces block discharge section 7 is generally designed to be a semi-wrapped arc shape, and the feces shoveling structure is double-inclined, specifically: the mesh 8 is provided on the separation section 6, and the separation section 6 is inclined downward from the cat entrance 3 to the feces outlet 4. The separation section 6 separates the cat litter and the feces blocks, and the cat litter passes through the mesh 8 and falls into the inner bucket 2. The feces discharge section 7 is inclined from the separation section 6 toward the feces outlet 4, and the setting height of the feces discharge section 7 gradually increases from the separation section 6 toward the feces outlet 4. The rear part of the feces discharge section 7 extends into the feces outlet 4, so that the feces discharge section 7 is inclined upward. When the inner barrel 2 rotates clockwise at a certain angle, the setting height of the feces discharge section 7 is adjusted to gradually decrease from the separation section 6 toward the feces outlet 4. After the rotation of the inner barrel 2, the feces discharge section 7 is inclined downward, and the feces separated by the separation section 6 gather in the feces discharge section 7 under the rotation of the inner barrel 2, and are discharged from the feces outlet 4 along the feces discharge section 7. In this way, when the cat litter and feces are separated, the feces discharge section 7 is tilted upward to reduce the cat litter from the feces outlet 4; when the inner barrel 2 rotates clockwise at a certain angle, the height of the feces discharge section 7 is adjusted to gradually decrease from the separation section 6 to the feces outlet 4, so that the feces discharge section 7 is tilted downward, so that the feces of large and small particles have a downward rolling force, which is convenient for quickly discharging the feces of large and small particles from the feces outlet 4, and improving the feces shoveling efficiency. Through the feces shoveling structure 5 of the above structure, the feces outlet 4 can be set at the center of the rear part of the inner barrel 2, and the inner barrel 2 can adapt to various shapes such as square, spherical, cylindrical and elliptical.

[0055] The separation section 6 includes a first plate 9, a second plate 10 and a material stopper 11. The first plate 9 is fixedly connected to the front of the inner barrel 2, the second plate 10 is connected to the feces discharge section 7, and the meshes 8 are distributed on the first plate 9 and the second plate 10. The meshes 8 on the first plate 9 are used to separate the cat litter and the feces for the first time, and the meshes 8 on the second plate 10 are used to separate the cat litter and the feces for the second time. When the inner barrel 2 rotates clockwise, the material stopper 11 blocks the cat litter, so that the cat litter can pass through the mesh 8 and fall into the inner barrel 2; and the separation section 6 is designed as the first plate 9 and the second plate 10, so that the structure of the separation section 6 can adapt to the structure of the feces discharge section 7, which is convenient for the later separation section 6 and the feces discharge section 7 to be integrally formed and manufactured, and the contact area and separation time of the separation section 6 with the cat litter and the feces can be increased, thereby improving the separation efficiency of the cat litter and the feces.

[0056] In actual operation, a small portion of cat litter will still be discharged from the feces outlet 4 along the feces scooping structure 5 of the innovative design of the present invention, resulting in a waste of cat litter. In view of this technical problem, a cat litter blocking portion 12 is provided between the second plate 10 and the feces block discharge section 7. The cat litter blocking portion 12 is tilted downward from the feces block discharge section 7 to the second plate 10. The top surface of the cat litter blocking portion 12 is an inclined surface. When a small portion of cat litter rolls from the second plate 10 to the feces block discharge section 7 during the separation stage of cat litter and feces, the cat litter blocking portion 12 blocks and slows down the cat litter, causing the cat litter to roll back onto the second plate 10 and pass through the mesh 8 of the second plate 10.

[0057] The mesh holes 8 on the first plate body 9 are arranged toward the second plate body 10, so that the length direction of the mesh holes 8 on the first plate body 9 is consistent with the direction in which the cat litter rolls on the first plate body 9, increasing the penetration area of ​​the cat litter on the first plate body 9, so that the cat litter can quickly pass through the mesh holes 8 on the first plate body 9. The mesh holes 8 on the second plate body 10 are arranged toward the feces block discharge section 7, so that the length direction of the mesh holes 8 on the second plate body 10 is consistent with the direction in which the cat litter rolls on the second plate body 10, increasing the penetration area of ​​the cat litter on the second plate body 10, so that the cat litter can quickly pass through the mesh holes 8 on the second plate body 10, and further improving the separation efficiency of cat litter and feces blocks.

[0058] The first plate body 9 is provided with a fixing plate 13, which is fixed to the front of the inner barrel 2 by fixing screws. The outer side of the feces discharge section 7 is provided with an outer ring plate 14, which is fixed to the rear of the inner barrel 2 by fixing screws, so that the feces scooping structure 5 can be detachably connected to the inner barrel 2, which is convenient for replacing and cleaning the entire feces scooping structure 5.

[0059] In the prior art, when the amount of cat litter is insufficient, clean cat litter needs to be poured in. At this time, the clean cat litter and the dirty cat litter are mixed together, affecting the use of the cat litter. Therefore, it is necessary to discharge the unused cat litter from the inner barrel 2. The operator generally directly shovels the cat litter in the inner barrel 2 with a shovel. The efficiency of shoveling the cat litter is low and the structure of the inner barrel 2 is easily damaged. If the cat litter is discharged by dumping the inner barrel 2, the structure in the smart cat litter box will fall off, affecting the operation of the smart cat litter box. Therefore, the feces scooping structure 5 of the present invention is provided with an automatic cat litter changing board 15, the shape of which matches that of the feces scooping structure 5, and the automatic cat litter changing board 15 blocks the mesh holes 8. When the cat litter in the smart cat litter box is insufficient, the user installs the automatic cat litter changing board 15 at the bottom of the feces scooping structure 5, and the automatic cat litter changing board 15 blocks the mesh holes 8 on the feces scooping structure 5, and then controls the inner barrel 2 to rotate in the basin body 1. At this time, with the coordinated use of the feces scooping structure 5 and the automatic cat litter changing board 15, the remaining dirty cat litter in the inner barrel 2 falls into the feces collecting bucket 29 through the feces outlet 4. After the dirty cat litter in the inner barrel 2 is discharged, the clean cat litter is poured back into the inner barrel 2, thereby achieving the effect of automatic cat litter changing, with high cat litter changing efficiency, without contacting the dirty cat litter, and the automatic cat litter changing operation does not affect the subsequent work of the entire smart cat litter box.

[0060] The poop scooping structure 5 is provided with a card block 16, which is preferably designed at the bottom of the poop scooping structure 5. The card block 16 can be designed into an L shape. The card block 16 is provided with a card slot 17, and the automatic cat litter changing plate 15 is arranged in the card slot 17, so that the automatic cat litter changing plate 15 can be quickly installed or disassembled on the poop scooping structure 5.

[0061] The cat litter that passes through the mesh 8 of the feces scooping structure 5 of the present invention does not return to the gathering center, and the cat litter will be eccentric, which is easy to cause the cat litter to fall from the cat inlet and outlet 3 of the inner bucket 2 to the outside, affecting the external environment. Therefore, a semi-wrapped silicone pad 18 is provided on the inner side of the inner bucket 2 of the present invention, and the silicone pad 18 is provided below the feces scooping structure 5. The silicone pad 18 gathers the cat litter separated and dropped by the feces scooping structure 5 to the center, so that the cat can enter to defecate next time, reducing the waste of cat litter.

[0062] Generally, the bottom of the silicone pad 18 near the cat entrance 3 is the first inclined portion 20, and the bottom of the silicone pad 18 near the feces outlet 4 is the second inclined portion 21. The inclination angle of the first inclined portion 20 is greater than the inclination angle of the second inclined portion 21. The inclination angle of the second inclined portion 21 can be designed to be 3-5 degrees, which ensures that the silicone pad 18 can centrally gather and return the cat litter separated and dropped by the feces shoveling structure 5, and can also make the bottom of the silicone pad 18 near the feces outlet 4 tend to be flat. The cat litter gathered on the silicone pad 18 is close to the feces outlet 4 set in the center, so that the feces and cat litter are formed into feces blocks as close to the feces outlet 4 as possible, shortening the rolling distance of the feces blocks on the feces shoveling structure 5, and further improving the feces shoveling efficiency.

[0063] A restraining member 19 is provided on the inner side of the inner barrel 2 , which fixes the top edge of the silicone pad 18 on the inner side of the inner barrel 2 . Since the silicone pad 18 is made of soft material, the restraining member 19 is required to fix it on the inner side of the inner barrel 2 to prevent the silicone pad 18 from shrinking on the inner barrel 2 .

[0064] The basin body 1 includes a bottom shell 22, a middle frame 23 and a top cover 24. The middle frame 23 is fixedly connected to the inside of the bottom shell 22. The inner barrel 2 is arranged in the middle frame 23. The top cover 24 and the middle frame 23 are detachably connected. The middle frame 23 is provided with a front bracket 30 and a rear bracket 25. A double-spin bearing 26 is fixedly connected between the front bracket 30 and the rear bracket 25. The double-spin bearing 26 is a customized structure. The inner barrel 2 is provided with a connecting shaft 27, and the connecting shaft 27 is rotatably connected to the double-spin bearing 26. The bottom shell 22 is provided with a motor, and the motor is provided with a transmission gear. A gear-like structure is provided on the outer side of the rear part of the inner barrel 2, and the transmission gear and the gear-like structure are meshed with each other.

[0065] A method for shoveling feces from an intelligent cat litter box with high efficiency of purification, deodorization and feces shoveling comprises the following steps:

[0066] a. Connect the power supply, press and hold the power switch for 3 seconds to turn on the smart cat litter box.

[0067] b. After turning on, the smart cat litter box will automatically perform weighing calibration to understand whether the cat has entered the smart cat litter box.

[0068] c. Put clean cat litter in the inner bucket 2, and the cat enters the inner bucket 2 through the cat inlet and outlet 3 at the front of the inner bucket 2 to defecate. At this time, automatic weighing is performed to calculate the defecation time. After the cat has finished defecating or urinating, the feces and urine and cat litter form feces blocks. After the cat has left the smart cat litter box for a period of time, the smart cat litter box is turned on and the smart cat litter box starts to shovel feces blocks. The inner bucket 2 rotates 1-2 circles clockwise in the box body 1. At this time, the cat litter and feces blocks are deposited in the inner bucket 2. The feces shoveling structure 5 separates the cat litter and feces blocks while shoveling the feces. The separation section 6 of the feces shoveling structure 5 separates the cat litter and feces blocks. The cat litter passes through the mesh 8 and falls into the inner bucket 2. The feces blocks separated by the separation section 6 gather in the feces block discharge section 7 and are discharged from the feces block discharge section 7. The feces blocks fall into the feces collecting bucket 29 at the rear of the smart cat litter box along the feces block discharge section 7, thereby improving the feces shoveling efficiency.

[0069] d. When all the feces fall into the collecting bucket 29, the inner bucket 2 is controlled to rotate two full circles in the basin body 1. After the inner bucket 2 returns to its original position, the silicone pad 18 reduces the centrifugal force deviation of the cat litter in the inner bucket 2 and gathers the cat litter in the center to facilitate the cat to enter the inner bucket 2 for defecation next time.

[0070] e. In the absence of a cat, turn on the ozone negative ion generator 28 on the smart cat litter box, press and hold the switch of the ozone negative ion generator 28 for 3 seconds to enter the automatic purification state. The generated negative ions will first precipitate the bacteria in the smart cat litter box, and release ozone for sterilization and deodorization at the same time. Sterilization and deodorization can be performed every 2 hours. Then use a fan to align the air outlet 3 of the cat to deodorize the smart cat litter box again. Then turn on the UV lamp on the smart cat litter box, and sterilize the smart cat litter box again through the UV lamp, realizing the integration of shoveling shit, sterilization and deodorization, improving the sterilization and deodorization ability of the smart cat litter box, improving the internal cleanliness of the smart cat litter box, and increasing the comfort of the smart cat litter box.

[0071] f. When the alarm on the smart cat litter box detects that there is insufficient cat litter, the alarm is triggered, and the user installs an automatic cat litter changing board 15 at the bottom of the feces scooping structure 5. The automatic cat litter changing board 15 blocks the mesh holes 8 on the feces scooping structure 5, and then controls the inner bucket 2 to rotate in the basin body 1. At this time, with the coordinated use of the feces scooping structure 5 and the automatic cat litter changing board 15, the remaining dirty cat litter in the inner bucket 2 falls into the feces collecting bucket 29 through the feces outlet 4. When the dirty cat litter in the inner bucket 2 is discharged, the clean cat litter is poured back into the inner bucket 2, achieving the technical effect of automatically changing cat litter.

[0072] G, take out the dirty cat litter in the cesspool 29 and clean and disinfect it, reclaim the cat litter, recycle the cat litter and reuse it to reduce the cost of cat litter purchase.

[0073] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
