DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See Figures 1 to 11.

[0040] The intelligent cat litter box of the embodiment of the present invention includes a base 1, a ball bin 2 that can rotate in a clockwise and counterclockwise direction on the base 1, a sand collecting bin 3 arranged in the ball bin 2 and capable of collecting cat litter as the ball bin 2 rotates, a feces collecting bin 4 arranged in the ball bin 2 and capable of collecting cat litter balls as the ball bin 2 rotates, and a cat litter placement area 5 arranged in the ball bin 2, wherein the cat litter in the cat litter placement area 5 can flow into the sand collecting bin 3 as the ball bin 2 rotates, and the cat litter in the sand collecting bin 3 can flow into the cat litter placement area 5 as the ball bin 2 rotates, and further includes:

[0041] The filter assembly 6 is arranged at the corresponding opening position of the sand collecting bin 3, and the edge of one side away from the sand collecting bin 3 can be in contact with the inner wall of the ball bin 2;

[0042] The connecting member 7 is arranged in the ball bin 2, and can be rotated together with the filter assembly 6 in the clockwise and counterclockwise directions, and can also be snap-fitted with the filter assembly 6 in its own circumferential direction.

[0043] The intelligent cat litter box of the present invention is provided with a filter assembly 6 and a connecting piece 7. The filter assembly 6 is installed at the opening position of the sand collecting bin 3 through the connecting piece 7 to separate the cat litter clumps from the cat litter, and the cat litter enters the sand collecting bin 3. Moreover, since the connecting piece 7 is rotatably connected to the filter assembly 6 and the filter assembly 6 and the connecting piece 7 are circumferentially engaged with each other in the connecting piece 7, when the filter assembly 6 needs to be cleaned, it can be disassembled by rotating the filter assembly 6 to the angle of engagement with the connecting piece 7. The disassembly operation is convenient and the filter assembly 6 is easy to clean.

[0044] In one embodiment, the connecting member 7 includes at least two symmetrically arranged connecting columns 701, and each of the connecting columns 701 is provided with a rotation groove 7011 along its own length direction, and at least one of the connecting columns 701 is also provided with a notch 7012 connected to the rotation groove 7011 on the circumference, and the filter assembly 6 includes a rotating shaft 601, and the two ends of the rotating shaft 601 can be rotatably engaged with the two rotating grooves 7011 respectively, and the rotating shaft 601 can also be snap-engaged with the notch 7012. With this design, a detachable connection is achieved through the snap-fit ​​cooperation between the rotating shaft 601 and the notch 7012. The structure is simple and easy to operate. In this embodiment, the width of the notch 7012 is slightly smaller than the diameter of the rotating shaft 601. In this embodiment, when a connecting column 701 is provided with a notch 7012, when removing the rotating shaft 601, it is sufficient to pull this end located at the rotating shaft 601. When both connecting columns 701 are provided with notches 7012, it is sufficient to pull the rotating shaft 601 along the plane direction where the notch 7012 is located.

[0045] In one embodiment, the filter assembly 6 further includes a connecting block 602 connected to the rotating shaft 601 and a filter 603 detachably connected to the connecting block 602. This design allows the filter 603 to be replaceable through the detachable connection between the filter 603 and the connecting block 602. By replacing the filter 603 with a filter having different pore sizes, different types of cat litter can be separated. In this embodiment, after the filter 603 is connected via the connecting block 602, when the filter assembly 6 needs to be removed, the rotating shaft 601 needs to be rotated to an angle that facilitates force application and then the filter 603 needs to be pulled.

[0046] In one embodiment, the pore size of the filter screen 603 gradually decreases along the direction of movement of the cat litter and the litter mass. This design allows more cat litter to be filtered through the large pores at the beginning when the ball bin 2 rotates. During the filtration process, the flow of the cat litter drives the movement of the cat litter mass, so that the movement of the cat litter mass is always slower than that of the cat litter. As the amount of cat litter decreases, the pore size is gradually reduced to ensure that cat litter mass does not pass through the pores and enter the sand collecting bin 3.

[0047] In one embodiment, the filter screen 603 is made of metal. This design can reduce the risk of cat litter sticking to the wall, and in this embodiment, the metal material can be stainless steel, aluminum alloy or galvanized steel, which is rust-proof and lightweight.

[0048] In one embodiment, the filter assembly 6 is wavy, with the rotationally connected side of the filter assembly 6 and the side away from the sand collecting bin 3 both located at the trough position. This design allows the cat litter to be accelerated and buffered as it passes through the filter assembly 6 as it rotates with the ball bin 2.

[0049] In one embodiment, it further includes:

[0050] Cat litter mat 8, used for holding cat litter;

[0051] The first flange 9 is provided in the cat litter placement area 5 and is arranged around the inner wall of the ball bin 2;

[0052] The clip-on fitting 10 is provided in the cat litter placement area 5 and can cooperate with the first flange 9 to clip the cat litter mat 8 to the inner side of the first flange 9. This design completely encloses the cat litter mat 8 by providing a circle of first flange 9. If a cat accidentally urinates on the inner wall of the ball bin 2, the urine will eventually flow along the first flange 9 onto the cat litter mat 8, preventing urine from flowing through the gaps at the edge of the cat litter mat 8 to the inner bottom of the ball bin 2.

[0053] In one embodiment, the snap-fit ​​fitting 10 includes at least a second flange 1001 spaced apart from the inner side of the first flange 9 and extending along the inner wall of the ball chamber 2. The cat litter mat 8 includes at least an elastic shaping strip 801 and a surface pad 802 covering the elastic shaping strip 801 and forming a cushioning layer with the elastic shaping strip 801. The elastic shaping strip 801 can be snapped between the first flange 9 and the second flange 1001. This design forms a groove structure with the second flange 1001 and the first flange 9. The elastic characteristics of the elastic shaping strip 801 allow the elastic shaping strip 801 to be pressed into the gap between the second flange 1001 and the first flange 9 during installation by squeezing the elastic shaping strip 801, making installation convenient. During removal, the elastic shaping strip 801 can be deformed and released from the gap between the second flange 1001 and the first flange 9 by squeezing the surface pad 802, making removal convenient. In this embodiment, the elastic shaping strip 801 can be made of metal.

[0054] In one embodiment, it further includes:

[0055] At least one assembly part 11 is detachably disposed in the ball chamber 2;

[0056] At least one deodorizing component 12, which is engaged with the assembly part 11 and can spray deodorant into the ball chamber 2;

[0057] The control unit 13 is arranged in the deodorizing component 12, and the control unit 13 controls whether the deodorizing component 12 sprays or not by detecting the rotation tilt angle of the ball bin 2. In this embodiment, the function of the control unit 13 is to first obtain an input tilt threshold value required by the outside, and then obtain the current rotation tilt value of the monitored ball bin 2, and finally compare the input tilt threshold value with the current tilt value; when the current tilt value is greater than or equal to the input tilt threshold value, the control unit 13 controls the deodorizing component 12 to operate and spray the deodorant into the ball bin 2; when the current tilt value is less than the input tilt threshold value, the control unit 13 controls the deodorizing component 12 not to spray. With this design, the control unit 13 realizes that the deodorizing component 12 is independent of the smart litter box, and can control whether the deodorizing component 12 sprays or not without the control logic of the control system of the smart litter box. There is no incompatibility problem with the smart litter box, and the repair cost can be reduced when it is damaged.

[0058] In one embodiment, the assembly 11 includes at least a connecting bolt 1101, and the deodorizing assembly 12 includes at least a housing 1201 and a plurality of elastic snap-fit ​​strips 1202. The housing 1201 has a mounting hole 1203 through which the connecting bolt 1101 passes. The plurality of elastic snap-fit ​​strips 1202 are disposed within the housing 1201 and are tapered around the mounting hole 1203. The plurality of elastic snap-fit ​​strips 1202 snap-fit ​​with the connecting bolt 1101. In this embodiment, the snap-fit ​​end of the connecting bolt 1101 is mushroom-shaped, and the snap-fit ​​surfaces of the plurality of elastic snap-fit ​​strips 1202 are arc-shaped and can be attached to the bottom of the snap-fit ​​end of the connecting bolt 1101.

[0059] In one embodiment, the assembly 11 further includes a connection plate 1102 connected to the connection bolt 1101, and the connection plate 1102 is detachably connected to the ball chamber 2. In this embodiment, the connection plate 1102 can be detachably connected to the ball chamber 2 by gluing or screws.

[0060] In one embodiment, the deodorizing assembly 12 further includes a deodorant bottle 1207 and an atomizing nozzle 1204. A receiving cavity 1205 is provided on the exterior of the housing 1201. The deodorant bottle 1207 is disposed within the receiving cavity 1205, and the mouth of the deodorant bottle 1207 is located within and detachably connected to the housing 1201. The atomizing nozzle 1204 is disposed within the housing 1201 and detachably connected to the mouth of the deodorant bottle 1202. This design allows the deodorant bottle 1202 to be directly replaced after the deodorant inside is used up, and since it is disposed outside the housing 1201 via the receiving cavity 1205, it is easily disassembled.

[0061] In one embodiment, the control unit 13 includes a sensor 1301 for detecting the rotation angle of the ball chamber 2, and a control board 1302 for receiving inclination data transmitted by the sensor 1301 and controlling the deodorizing assembly 12 on and off based on the inclination data. In this embodiment, the sensor 1301 can be a mechanical gyroscope or a fiber optic gyroscope, as known in the art, and the control board 1302 can be a single-chip microcomputer or a small PLC board, as known in the art.

[0062] In one embodiment, the housing 1201 further houses a battery 1206 for powering the atomizing nozzle 1204, the control board 1302, and the sensor 1301. This design allows for independent power from the battery 1206, eliminating the need for information exchange with the smart litter box's own control system. The deodorization process is triggered solely by monitoring the rotation angle of the ball bin 2, simplifying the deodorization process.

[0063] In one embodiment, it further includes:

[0064] The feces collection bin door 14 is located at the opening of the feces collection bin 4 and includes at least a sealing plate 1401 that can be elastically rotated only within the feces collection bin 4. This design allows the sealing plate 1401 to automatically open when a litter ball enters the feces collection bin 4 and automatically close after entering the feces collection bin 4, preventing the litter ball from falling out of the opening of the feces collection bin 4. In this embodiment, the elastic rotation connection of the sealing plate 1401 can be achieved by a torsion spring.

[0065] In one embodiment, it further includes:

[0066] The tie ring 15 is engaged with the excrement collection bin door 14 and can fix the garbage bag in the excrement collection bin 4 and connect the bag opening of the garbage bag with the opening of the excrement collection bin 4. In this design, the bag opening of the garbage bag is fixed by the tie ring 15, so as to prevent the cat litter ball from pulling the garbage bag when entering the garbage bag from the opening of the excrement collection bin 4, causing the garbage bag to fall out of the excrement collection bin door 14.

[0067] In one embodiment, the tie ring 15 comprises at least a first ring body 1501, two ears 1502 elastically disposed on either side of the first ring body 1501, and two clips 1503 disposed on the outer sides of the ears 1502. Two clips 401 are also disposed on the walls of the two sides of the opening of the feces collection bin 4, and each of the clips 401 is provided with a slot 4011 that engages with the two clips 1503. With this design, when securing the garbage bag, the edge of the opening of the garbage bag is wrapped around the first ring body 1501, and then the two ears 1502 are pressed together to engage the two clips 1503 in the slots 4011, thereby securing the tie ring 15. When removing the garbage bag, the two ears 1502 are similarly squeezed together to disengage the two clips 1503 from the slots 4011.

[0068] In one embodiment, the excrement collection bin door 14 further includes a second ring body 1402. The bottom of the first ring body 1501 is further provided with a protrusion 1504. The second ring body 1402 is further provided with a groove 1403 that plugs into the protrusion 1504. This design allows the protrusion 1504 to partially engage the groove 1403 when the garbage bag is being secured, thereby securing the garbage bag more securely. In this embodiment, the sealing plate 1401 is elastically rotatably connected to the second ring body 1402.

[0069] In one embodiment, at least one pressing block 402 for squeezing the first ring body 1501 can be detachably provided on the wall of the feces collecting bin 4. This design increases the squeezing force by adding the pressing block 402 to squeeze the first ring body 1501, making the garbage bag more firmly fixed.

[0070] In one embodiment, it further includes:

[0071] The pedal 16 is provided at the entrance of the ball bin 2, and the tread surface of the pedal 16 is in an inwardly concave arc shape. With this design, when a cat enters the ball bin 2 to defecate, after stepping on the pedal 16, the cat litter stuck on the cat's paw can fall onto the upper surface of the pedal 16 and fall back into the ball bin 2 along with the pedal 16.

[0072] In one embodiment, the ball bin 2 is further provided with a sand drain outlet at the position corresponding to the bin door. This design facilitates the discharge of cat litter and sewage when cleaning the interior of the ball bin 2.

[0073] In one embodiment, it further includes:

[0074] The barrel ring 17 is detachably mounted at the door of the ball bin 2. With this design, the barrel ring 17 shields the sand and water outlet, and under the shielding of the barrel ring 17, the door of the ball bin 2 can be made as large as possible to facilitate cleaning of the ball bin 2. Finally, the barrel ring 17 controls the size of the door of the ball bin 2 to be just large enough for the cat to enter and exit, thereby preventing the door of the ball bin 2 from being too large, causing the cat to scrape the litter outside the ball bin 2 when digging.

[0075] In the present invention, the entire defecation control process and deodorization process of the smart cat litter box is to detect whether there is a cat in the ball bin 2 through the gravity sensor. If there is no cat, the ball bin 2 will not move. If the timing reaches a certain time, the ball bin 2 will rotate counterclockwise, and then rotate clockwise after a period of time. When the sensor 1301 detects that the clockwise rotation angle exceeds the specified threshold, the deodorization component 12 is started to spray deodorant into the ball bin 2. This section of the control system can be implemented through existing technology and will not be elaborated here.

[0076] In summary, the smart cat litter box of the embodiment of the present invention is provided with a filter assembly 6 and a connecting piece 7. The filter assembly 6 is installed at the opening position of the sand collecting bin 3 through the connecting piece 7 to separate the cat litter from the cat litter, and the cat litter enters the sand collecting bin 3. Moreover, since the connecting piece 7 is rotatably connected to the filter assembly 6 and the filter assembly 6 and the connecting piece 7 are engaged with each other in the circumferential direction of the connecting piece 7, when the filter assembly 6 needs to be cleaned, the filter assembly 6 can be disassembled by rotating the filter assembly 6 to the angle of engagement with the connecting piece 7. The disassembly operation is convenient and the filter assembly 6 is easy to clean.

[0077] By providing a circle of first flanges 9 to completely enclose the cat litter mat 8, when the cat accidentally urinates on the inner wall of the ball bin 2, the urine will eventually flow along the first flanges 9 to the cat litter mat 8, preventing the urine from flowing through the edge gaps of the cat litter mat 8 to the inner bottom of the ball bin 2;

[0078] The control unit 13 enables the deodorizing component 12 to be independent of the smart litter box, and the spraying of the deodorant in the deodorizing component 12 can be controlled independently of the control logic of the control system of the smart litter box. There is no incompatibility problem with the smart litter box, and the repair cost can be reduced in the event of damage.
