[0041] In the following description, many specific details are set forth in order to provide a thorough understanding of this specification. However, this specification can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of this specification. Therefore, this specification is not limited by the specific implementations disclosed below.

[0042] The terms used in one or more embodiments of this specification are for the purpose of describing specific embodiments only and are not intended to limit one or more embodiments of this specification. The singular forms "a" and "the" used in one or more embodiments of this specification and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise.

[0043] It should be understood that although the terms first, second, etc. may be used in one or more embodiments of this specification to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0044] In this specification, a cleaning control method for an intelligent litter box is provided. This specification also relates to a cleaning control unit for an intelligent litter box and an intelligent litter box, which will be described in detail one by one in the following embodiments.

[0045] See Figure 1 , Figure 1 shows a flowchart of a cleaning control method for an intelligent litter box provided according to an embodiment of this specification. The intelligent litter box includes a separately rotatable litter scoop and an inner bin of the litter box. The inner bin of the litter box is generally hemispherical, or the inner bin of the litter box is an arc semi-circle with a U-shaped cross-section and can rotate around the center of the circle. The litter scoop and the inner bin of the litter box can rotate relative to each other coaxially. The litter scoop can rotate in the inner bin of the litter box, and when the litter scoop rotates in the inner bin of the litter box, it abuts against the inner bin of the litter box. The method specifically includes the following steps 102-106.

[0046] Step 102: Receive a cleaning instruction for the intelligent litter box, where the cleaning instruction carries a target cleaning mode, and the target cleaning mode is any one or more of at least one cleaning mode supported by the intelligent litter box.

[0047] It should be noted that the intelligent litter box can support at least one cleaning mode, such as a dirty waste removal mode, a waste sand emptying mode, a water flushing and cleaning mode, a drying mode, etc. Among them, the dirty waste refers to fecal masses, urine masses, etc. generated by the cat's excretion. Specifically, when implementing, the user can carry the target cleaning mode that needs to be performed currently when triggering the cleaning instruction, and the target cleaning mode can be one or more.

[0048] It should be noted that the intelligent litter box at least includes a separately rotatable litter scoop and an inner bin of the litter box. The inner bin of the litter box is used to place cat litter, and the cat can enter the inner bin of the litter box to excrete on the cat litter. After the cat excretes, it is necessary to timely remove the dirt generated by the cat's excretion on the cat litter, and regularly clean the litter scoop and the inner bin of the litter box. Therefore, when the user needs to clean the intelligent litter box, the user can select the corresponding cleaning mode to trigger the cleaning instruction. Specifically, the main body of the litter scoop includes a plurality of support structures, and the plurality of support structures are arranged at intervals along the extending direction of the main body of the litter scoop. The intervals between the plurality of support structures of the main body of the litter scoop are used to filter out the clean cat litter, and the dirt can be shoveled up by the litter scoop.

[0049] In practical applications, a cleaning control can be set on the intelligent litter box. The cleaning control can be an actual physical button or a click position on a touch display screen. The user can trigger the cleaning control on the intelligent litter box to trigger a cleaning instruction carrying a target cleaning mode. Of course, it can also be remotely controlled through an APP program.

[0050] In another implementation, an automatic cleaning logic can also be pre-configured in the intelligent litter box. The automatic cleaning logic can be to automatically trigger a cleaning instruction corresponding to a target cleaning mode when a set condition is met. For example, the automatic cleaning logic can be: after detecting that the cat enters the intelligent litter box and then leaves the intelligent litter box after a set time, trigger a cleaning instruction corresponding to the dirt removal mode; trigger a cleaning instruction corresponding to the waste sand emptying mode every first set time period, and trigger a cleaning instruction corresponding to the water flushing and cleaning mode every second set time period, where the first set time period can be less than the second set time period; or it can automatically trigger a cleaning instruction corresponding to the water flushing and cleaning mode after detecting that the waste sand emptying mode is completed; trigger a drying mode after detecting that the water flushing and cleaning mode is completed, etc.

[0051] Of course, other automatic cleaning logics can also be configured based on actual scenario requirements, and the embodiments of this specification do not limit this.

[0052] Step 104: Define a plurality of regions for the circumferential space corresponding to the rotation of the inner bin of the litter box with the center of the circle as the origin of the coordinate system.

[0053] It should be noted that the litter scoop can rotate in the circumferential region corresponding to the inner bin of the litter box. In order to facilitate accurately controlling the rotation of the litter scoop to the corresponding position to achieve the corresponding cleaning function, the circumferential space corresponding to the inner bin of the litter box can be defined as a plurality of regions with the center of the circle as the origin of the coordinate system, which is convenient for controlling the rotation of the litter scoop to the target region corresponding to the target cleaning mode in the future.

[0054] In practical applications, a coordinate system can be established with the rotation center (i.e., the center of the circle) of the inner bin of the litter box as the origin of the coordinate system, and each quadrant in this coordinate system is defined as a plurality of regions. Additionally, in specific implementations, the defined regions can be automatically defined by the cleaning control unit of the intelligent litter box according to certain rules, or can be multiple regions defined manually.

[0055] As an example, Figure 2 is a schematic diagram of region definition provided by an embodiment of this specification. As Figure 2 shown, the middle position of the opening of the inner bin of the litter box can be used as the origin coordinate to establish a coordinate system. In this coordinate system, the right side of the inner bin of the litter box is in the fourth quadrant, the left side is in the third quadrant, the upper right side of the inner bin of the litter box is in the first quadrant, and the upper left side of the inner bin of the litter box is in the second quadrant. Each quadrant in this coordinate system is defined as a region.

[0056] Step 106: Control the litter scoop to rotate to the target region corresponding to the target cleaning mode, and control the inner bin of the litter box to rotate to the target position corresponding to the target cleaning mode to implement the cleaning task in the target cleaning mode.

[0057] It should be noted that the intelligent litter box can support at least one cleaning mode, and different cleaning modes can correspond to different rotation control logics. Therefore, after receiving a cleaning instruction, based on the target cleaning mode carried by the cleaning instruction, the rotation control logic corresponding to the target cleaning mode can be adopted to control the litter scoop to rotate to the target region corresponding to the target cleaning mode, and control the inner bin of the litter box to rotate to the target position corresponding to the target cleaning mode, where the target region and the target position are determined based on the rotation control logic corresponding to the target cleaning mode.

[0058] In an optional implementation manner of this embodiment, the target cleaning mode is the mode of removing dirt; controlling the litter scoop to rotate to the target region corresponding to the target cleaning mode, and controlling the inner bin of the litter box to rotate to the target position corresponding to the target cleaning mode to implement the cleaning task in the target cleaning mode includes:

[0059] Control the litter scoop to rotate from the area where it is standby to the first position in the first region, and scoop up the dirt in the inner bin of the litter box, where the first region is the area close to the dirt dumping side;

[0060] Control the inner bin of the litter box to rotate to the dirt dumping position, and at the same time control the litter scoop to rotate in the reverse direction from the first position in the first region to the second position in the first region;

[0061] Control the litter scoop to sprinkle the dirt out of the inner bin of the litter box at a set speed;

[0062] Control the inner bin of the litter box to rotate back to the standby position, and control the litter scoop to rotate back to the area where it is standby.

[0063] It should be noted that the mode of cleaning dirt refers to the mode of mixing the dirt generated by the cat's excretion with the cat litter originally filled in the inner bin of the litter box and shoveling it into a mass and collecting it into the sewage collection bin. The sewage collection bin refers to the collection device arranged below the inner bin of the litter box, which can be used to collect the shoveled dirt, or the discharged waste sand, sewage, etc.

[0064] In practical applications, the area where the litter shovel is in standby refers to the area corresponding to the position where the litter shovel is not rotating. When the litter shovel is located in this area, it does not affect the cat's entry and activities in the inner bin of the litter box. The first position in the first area refers to the position in the area that is convenient for shoveling the dirt from the inner bin of the litter box and separating the dirt from the clean cat litter. The first area is the area close to the dirt dumping side. The first position forms an obtuse angle with the direction of gravity, that is, the side of the inner bin of the litter box corresponding to the sewage collection bin, which is convenient for dumping the shoveled dirt into the sewage collection bin.

[0065] It should be noted that the area where the litter shovel is in standby can be on the edge side of the inner bin of the litter box and is the side far from the direction where the cat enters the inner bin. In the embodiments of this specification, the litter shovel is located inside the edge of the inner bin of the litter box and in contact with its inner surface at the standby position, ensuring that the litter shovel is inside the inner bin of the litter box, that is, ensuring that the litter shovel is in direct contact with the wall surface of the inner bin of the litter box.

[0066] In addition, the dirt dumping position refers to the position where the litter shovel can throw the shoveled dirt out of the inner bin of the litter box and sprinkle it into the sewage collection bin. The dirt dumping position corresponds to the setting position of the sewage collection bin, that is, controlling the inner bin of the litter box to tilt towards the side where the sewage collection bin is located, so that the litter shovel can sprinkle the shoveled dirt into the sewage collection bin. The second position in the first area refers to the position where the litter shovel sprinkles the shoveled dirt. The second position in the first area is set based on the dirt dumping position, so that the dirt can be sprinkled from the inner bin of the litter box into the sewage collection bin. Specifically, when implemented, the second position forms an acute angle with the direction of gravity, reducing the sprinkling height and avoiding sprinkling outside the sewage collection bin.

[0067] In the embodiments of this specification, in the mode of cleaning dirt, the litter scoop can be first controlled to rotate from the area where it is in standby to the first position in the first area, so as to scoop up the dirt in the inner bin of the litter box and separate it from the clean litter. Then, the inner bin of the litter box can be controlled to rotate to the dirt dumping position, and at the same time, the litter scoop can be controlled to rotate in the reverse direction from the first position in the first area to the second position in the first area to prepare for the throwing action. After that, the litter scoop is controlled to throw the dirt to the dirt collection bin at a set speed, and the inner bin of the litter box is controlled to rotate back to the standby position, and the litter scoop is controlled to rotate back to the area where it is in standby, completing the entire process of cleaning dirt. In this way, through the rotation logic of sequentially controlling the litter scoop to rotate to the first position in the first area - the inner bin of the litter box rotates to the dirt dumping position, the litter scoop rotates to the second position in the first area - the litter scoop performs the throwing action - both the inner bin of the litter box and the litter scoop return to the standby position, the dirt is automatically removed without the need for user intervention, saving time and effort, liberating the user's hands, and making it cleaner when the user raises a pet.

[0068] In an optional implementation manner of this embodiment, controlling the litter scoop to rotate from the area where it is in standby to the first position in the first area includes:

[0069] Controlling the litter scoop to rotate from the area where it is in standby to the third position in the first area;

[0070] Controlling the inner bin of the litter box to rotate from the standby position to the anti-overflow position;

[0071] Controlling the litter scoop to rotate from the third position in the first area to the first position.

[0072] In one implementation manner, the litter scoop can be directly controlled to rotate from the area where it is in standby to the first position in the first area, scoop up the dirt from the inner bin of the litter box, and separate the dirt from the clean litter.

[0073] In another implementation manner, since during the rotation of the litter scoop, the litter and the inner bin of the litter box may accumulate, when the litter scoop approaches the edge of the inner bin of the litter box, a part of the clean litter accumulated on the litter scoop may overflow to the outside, wasting the litter. Therefore, the litter scoop can also be first controlled to rotate from the area where it is in standby to the third position in the first area, and the third position is lower than the first position. First, the dirt in the inner bin of the litter box is scooped up a certain distance, and then the inner bin of the litter box is controlled to rotate from the standby position to the anti-overflow position first, and then the litter scoop is continuously controlled to rotate from the third position in the first area to the first position. Among them, the anti-overflow position refers to the position where one side edge of the inner bin of the litter box rotates and lifts obliquely to avoid the litter overflowing during the rotation of the litter scoop. Specifically, the inner bin of the litter box can be lifted by a certain angle towards the side of the third position where the litter scoop is currently located to avoid the litter overflowing.

[0074] In addition, the third position also forms an acute angle with the direction of gravity, and the third position may be the same as or different from the second position.

[0075] In the embodiments of this specification, the cat litter scoop can be first controlled to move to a lower third position to scoop up the dirty matter to a certain height, then the rotation of the cat litter scoop is controlled to stop, and the inner bin of the cat litter box is controlled to be lifted towards the dumping side. Under the action of gravity, the cat litter originally accumulated on the cat litter scoop moves away from the opening of the inner bin of the cat litter box and flows back to the clean cat litter. Then, the cat litter scoop is controlled to rotate to the first position to prevent the cat litter from overflowing when the cat litter scoop rotates to the edge of the inner bin of the cat litter box.

[0076] In an alternative embodiment of this example, controlling the cat litter scoop to sprinkle the dirty matter out of the inner bin of the cat litter box at a set speed includes:

[0077] Controlling the inner bin of the cat litter box to be fixed at the dirty matter dumping position, and controlling the cat litter scoop to rotate at a set speed beyond the edge of the inner bin of the cat litter box and then return, forming a sprinkling action to sprinkle the dirty matter out of the inner bin of the cat litter box.

[0078] Specifically, the cat litter scoop can be controlled to rotate at a set speed by a set angle, cross the edge of the inner bin of the cat litter box, and return to the second position in the first area at a set speed, forming a sprinkling action to sprinkle the dirty matter out of the inner bin of the cat litter box. Among them, the set speed refers to the speed of the sprinkling action performed by the cat litter scoop, and this speed is greater than the speed when the cat litter scoop rotates in the inner bin. The set speed can be pre-configured, such as 5 RPM (i.e., 5 revolutions per minute), 10 RPM (i.e., 10 revolutions per minute), etc. The set angle is the angle at which the cat litter scoop rotates to cross the edge of the inner bin of the cat litter box. This set angle needs to be greater than the angle between the cat litter scoop and the opening edge of the inner bin of the cat litter box, so that the cat litter scoop can cross beyond the edge of the inner bin of the cat litter box to ensure that the dirty matter is thrown out of the inner bin of the cat litter box and falls into the dirt collection bin.

[0079] It should be noted that the inner bin of the cat litter box can be controlled to be fixed at the dirty matter dumping position, and the cat litter scoop can be controlled to rotate at a set speed beyond the edge of the inner bin of the cat litter box and then return, forming a sprinkling action. The dirty matter on the cat litter scoop is ejected and quickly cleared through a rapid throwing action, realizing the automatic clearing of the dirty matter in the inner bin of the cat litter box without the need for user intervention, saving time and effort, liberating the user's hands, and making it cleaner when the user raises a pet.

[0080] As an example, Figures 3a - 3f is a schematic diagram of the rotation logic in the dirty matter clearing mode provided by an embodiment of this specification. As Figures 3a - 3f shown, taking the dirt collection bin being arranged below the left side of the inner bin of the cat litter box as an example for illustration, that is, dumping the dirty matter from the left side of the inner bin of the cat litter box, and defining the vertical position as the 0° position.

[0081] Controlling the inner bin of the cat litter box and the cat litter scoop from as Figure 3aRotate the shown standby position to as Figure 3b the position shown, that is, control the inner bin of the litter box to remain horizontally fixed (the angle with the direction of gravity is 0°), control the litter scoop to rotate clockwise from the fourth quadrant (that is, near the right edge position of the inner bin, and this right edge position of the inner bin is the area where the litter scoop is in standby, such as -87°) to the third quadrant (that is, the third position in the first area, such as +54°), and shovel up the dirty substances such as urine clumps and feces clumps from the litter and lift them to a certain height.

[0082] After that, control the litter scoop to stop rotating, and control the inner bin of the litter box to rotate clockwise by a certain angle (such as +10°) and then stop (the position where the inner bin of the litter box stops is the anti-overflow sand position), and then control the litter scoop to further rotate clockwise from the third quadrant (such as +54°) to the second quadrant (that is, the first position, such as +93°), as Figure 3c shown. This process can fully separate the clean litter from the dirty substances such as urine clumps and feces clumps.

[0083] After that, control the inner bin of the litter box and the litter scoop to rotate counterclockwise. The inner bin of the litter box rotates from the anti-overflow sand position (such as +10°) to the dirty substance dumping position (such as -36°), and the litter scoop rotates from the second quadrant (that is, the first position, such as +93°) to the third quadrant (that is, the second position, such as +54°), as Figure 3d shown. At this time, the inner bin of the litter box stops rotating, and the litter scoop rotates clockwise quickly at a speed greater than 5 RPM (5 revolutions per minute) by 5° and then returns to the +54° position at the same speed, forming a throwing action, that is, the litter scoop rotates over the edge of the inner bin and then returns to enter the inner bin, and dumps the filtered urine clumps and feces clumps and other dirty substances into the sewage collection bin, as Figure 3e shown.

[0084] After that, control the inner bin of the litter box to rotate clockwise from the dirty substance dumping position (-36°) to the standby position (0°), and the litter scoop rotates clockwise from the third quadrant to the fourth quadrant (the standby area, such as -87°). At this time, the inner bin of the litter box and the litter scoop rotate to the standby position, as Figure 3f shown, completing the entire feces shoveling and feces dumping functions and realizing the removal of dirty substances.

[0085] It should be noted that the above positions such as -87°, +54°, 10°, +93°, -36° are all for illustrative purposes. In actual applications, they can be adjusted and configured according to the specific size and shape of the litter scoop, the size and shape of the inner bin of the litter box, the installation position between the litter scoop and the inner bin of the litter box, and the actual scenario requirements. The embodiments of this specification do not limit this.

[0086] In an alternative embodiment of this example, the target cleaning mode is the waste sand dumping mode; control the cat litter shovel to rotate to the target area corresponding to the target cleaning mode, and control the inner bin of the cat litter box to rotate to the target position corresponding to the target cleaning mode to implement the cleaning task in the target cleaning mode, including:

[0087] Control the inner bin of the cat litter box to rotate to the waste sand dumping position, and dump the waste sand in the inner bin of the cat litter box to the outside.

[0088] It should be noted that the waste sand dumping mode refers to the mode of dumping the waste sand in the inner bin of the cat litter box into the sewage collection bin. Specifically, the waste sand dumping position refers to the position where the waste sand in the inner bin of the cat litter box can be completely dumped into the sewage collection bin. This waste sand dumping position corresponds to the installation position of the sewage collection bin, that is, control the inner bin of the cat litter box to tilt towards the side where the sewage collection bin is located, and the tilt angle is relatively large, so as to completely dump the waste sand in the inner bin of the cat litter box into the sewage collection bin.

[0089] In the embodiment of this specification, in the waste sand dumping mode, the inner bin of the cat litter box can be controlled to rotate to the waste sand dumping position, and the waste sand in the inner bin of the cat litter box can be dumped to the outside, such as dumped into the sewage collection bin, and then control the inner bin of the cat litter box to rotate back to the standby position to complete the entire waste sand dumping process. In this way, through the rotation logic of controlling the inner bin of the cat litter box to rotate to the waste sand dumping position - the inner bin of the cat litter box rotates back to the standby position in sequence, the waste sand is automatically dumped without user intervention, saving time and effort, liberating the user's hands, and making it cleaner when the user raises pets.

[0090] In an alternative embodiment of this example, before controlling the inner bin of the cat litter box to rotate to the waste sand dumping position and dumping the waste sand in the inner bin of the cat litter box into the sewage collection bin, it further includes:

[0091] Control the cat litter shovel to rotate from the area where it is in standby to the second area, where the second area is an area outside the inner bin of the cat litter box and opposite to the waste sand dumping side.

[0092] Specifically, the second area is an area outside the inner bin of the cat litter box and opposite to the waste sand dumping side, that is, a position that does not block the dumping of the waste sand in the inner bin of the cat litter box.

[0093] In practical applications, if the cat litter shovel is located inside the inner bin of the cat litter box, when dumping the waste sand in the inner bin of the cat litter box, it may block the falling of the waste sand, resulting in incomplete dumping of the waste sand. Therefore, in the embodiment of this specification, the cat litter shovel can be controlled to rotate from the area where it is in standby to the second area or other positions to move out of the inner bin of the cat litter box, ensuring that when the inner bin of the cat litter box is subsequently controlled to rotate to the waste sand dumping position and the waste sand in the inner bin of the cat litter box is dumped, no waste sand will fall on the cat litter shovel, ensuring complete dumping of the waste sand.

[0094] Moreover, since the litter scoop is first removed from the inner bin of the litter box, and then during the rotation of the inner bin of the litter box, while the waste sand is falling, due to the rotation of the inner bin of the litter box, the litter scoop enters the inner bin of the litter box from the edge of the inner bin of the litter box until the inner bin of the litter box stops rotating. During this process, the inner bin of the litter box in contact with the litter scoop can be scraped, and the waste sand remaining on the inner wall of this part of the inner bin of the litter box is scraped clean, ensuring the full cleaning of the waste sand.

[0095] In an optional implementation manner of this embodiment, after controlling the inner bin of the litter box to rotate to the waste sand dumping position and dumping the waste sand in the inner bin of the litter box to the outside, it further includes:

[0096] Controlling the inner bin of the litter box to be fixed at the waste sand dumping position and controlling the litter scoop to rotate a set number of turns to scrape the remaining waste sand in the inner bin of the litter box.

[0097] It should be noted that after the inner bin of the litter box rotates to the waste sand dumping position, under the action of gravity, the waste sand will fall into the lower sewage collection bin to achieve the dumping of the waste sand. However, there will be some waste sand remaining on the inner wall of the inner bin of the litter box. Therefore, it is also possible to control the inner bin of the litter box to be fixed at the waste sand dumping position and control the litter scoop to rotate a set number of turns to scrape the remaining waste sand in the inner bin of the litter box, and then control the litter scoop to return to the standby area. In this way, since the litter scoop is in contact with the inner bin of the litter box, by rotating the litter scoop, the remaining waste sand in the inner bin of the litter box can be scraped, ensuring the full removal of the waste sand in the inner bin of the litter box, thereby ensuring the cleanliness and hygiene of the inner bin of the litter box, and there is no need to clean the inner bin of the litter box every time the litter is changed, saving cleaning resources.

[0098] As an example, Figures 4a - 4e is a schematic diagram of the rotation logic in the waste sand dumping mode provided by an embodiment of this specification. As Figures 4a - 4e shown, taking the sewage collection bin being arranged below the left side of the inner bin of the litter box as an example for illustration, that is, dumping the waste sand from the left side of the inner bin of the litter box, and defining the vertical position as the 0° position.

[0099] Controlling the inner bin of the litter box and the litter scoop to rotate from the standby position as Figure 4a shown to the position as Figure 4b shown, that is, controlling the inner bin of the litter box to remain horizontally fixed (the included angle with the gravity direction is 0°), and controlling the litter scoop to rotate counterclockwise from the fourth quadrant (that is, the standby area, such as -87°) to the first quadrant (that is, the second area, such as -135°);

[0100] After that, controlling the litter scoop to be fixed and controlling the inner bin of the litter box to rotate counterclockwise from the standby position (such as 0°) to the waste sand dumping position (such as -100°), as Figure 4cAs shown, at this time, the waste cat litter in the inner bin of the litter box is poured into the sewage collection bin. By first rotating the litter scoop to the first quadrant, the litter scoop can be rotated outside the inner bin of the litter box. Then, when the inner bin of the litter box is rotated to the waste litter dumping position, the litter scoop that was originally outside the bin can scrape the contact part between the litter scoop and the inner bin of the litter box after the litter scoop enters the inner bin of the litter box, avoiding areas at the edge of the inner bin of the litter box that are not scraped and leaving no cleaning dead corners.

[0101] After that, control the inner bin of the litter box to be fixed, and control the litter scoop to rotate clockwise for multiple circles and then rotate back to the standby area in the fourth quadrant (such as -87°), as Figure 4d shown. In this process, the remaining waste litter in the inner bin of the litter box can be scraped into the sewage collection bin by the litter scoop, reducing the residual waste litter.

[0102] After that, control the inner bin of the litter box to rotate clockwise from the waste litter dumping position to the standby position, restoring the standby position state, as Figure 4e shown, completing the function of automatically cleaning the waste litter.

[0103] It should be noted that the above positions such as -87°, -135°, -100°, etc. are only for illustrative purposes. In actual applications, adjustments can be made according to the specific size and shape of the litter scoop, the size and shape of the inner bin of the litter box, the installation position between the litter scoop and the inner bin of the litter box, and the actual scenario requirements. The embodiments of this specification do not limit this.

[0104] In an optional implementation manner of this embodiment, the intelligent litter box further includes a water spraying member, and the target cleaning mode is the water flushing cleaning mode; control the litter scoop to rotate to the target area corresponding to the target cleaning mode, and control the inner bin of the litter box to rotate to the target position corresponding to the target cleaning mode to implement the cleaning task in the target cleaning mode, including:

[0105] The water spraying member is filled with water to inject water into the inner bin of the litter box;

[0106] After the water injection ends, control the inner bin of the litter box to rotate back and forth a set number of times;

[0107] Control the inner bin of the litter box to rotate to the sewage dumping position to pour out the sewage from the inner bin of the litter box.

[0108] It should be noted that a water spraying member can also be set in the intelligent litter box. In one possible implementation manner, the water spraying member can be correspondingly arranged with the litter scoop, and the water spraying member sprays water flow on the litter scoop. After the water flow washes the litter scoop, it flows into the inner bin of the litter box, realizing water injection into the inner bin of the litter box, and then washing the inner bin of the litter box, realizing the water flushing cleaning of the litter scoop and the inner bin of the litter box. After the water flushing cleaning, the sewage is poured out of the inner bin of the litter box and collected in the sewage tank. In another possible implementation manner, the water spraying member can also be directly correspondingly arranged with the inner bin of the litter box to directly inject water into the inner bin of the litter box.

[0109] In specific implementation, the water spraying member can be arranged inside the cat litter scoop main body or outside the cat litter scoop main body. The water spraying member is arranged corresponding to the cat litter scoop, so that the water flow sprayed by the water spraying member flows towards the cat litter scoop, passes through the cat litter scoop and then flows into the inner bin of the cat litter box. Then, by controlling the relative rotation between the cat litter scoop and the inner bin of the cat litter box, the automatic cleaning of the cat litter scoop and the inner bin of the cat litter box is realized, ensuring the cleanliness and hygiene of the intelligent cat litter box and improving the cleaning efficiency.

[0110] In addition, the sewage dumping position refers to the position where all the sewage in the inner bin of the cat litter box can be dumped into the sewage tank. This sewage dumping position corresponds to the setting position of the sewage tank, that is, controlling the inner bin of the cat litter box to tilt towards the side where the sewage tank is located, and the tilt angle is relatively large, so as to dump all the sewage in the inner bin of the cat litter box into the sewage tank. Among them, the sewage tank refers to the collection device for collecting the sewage generated by cleaning. This sewage tank can be the same device as the sewage collection bin, that is, the sewage, the dirty substances generated by excretion, the waste sand, etc. are all collected into the sewage collection bin. Or, this sewage tank can be a different device from the sewage collection bin, and the sewage and the dirty substances and waste sand generated by excretion are collected separately.

[0111] In the embodiment of this specification, in the water passing and cleaning mode, water needs to be added to the intelligent cat litter box for cleaning. Therefore, it is necessary to first pour out all the waste sand in the inner bin of the cat litter box, that is, it is necessary to first execute the waste sand pouring mode. For the specific execution logic, refer to the detailed discussion in the above waste sand pouring mode. After pouring out the waste sand, the water adding device can be opened, the water spraying member passes water, and water is injected into the inner bin of the cat litter box. Specifically, water can be sprayed onto the cat litter scoop through the water spraying member, and the sprayed water flow will flow towards the cat litter scoop to clean the locally easily soiled surface of the cat litter scoop, and then flow into the inner bin of the cat litter box. After setting the water adding and cleaning duration, the water adding device can be controlled to be closed to end the water passing, and then the inner bin of the cat litter box is controlled to rotate back and forth (that is, left and right along the horizontal direction) a set number of times, so that the water in the inner bin of the cat litter box fully wets the surface of the inner bin of the cat litter box to clean the inner bin of the cat litter box. After that, the inner bin of the cat litter box is controlled to rotate to the sewage dumping position to dump the sewage out of the inner bin of the cat litter box, completing the water passing and cleaning of the intelligent cat litter box. In this way, through the rotation logic of first executing the waste sand pouring mode - passing water to the water spraying member - rotating the inner bin of the cat litter box - rotating the inner bin of the cat litter box to the sewage dumping position, the water passing and cleaning is automatically realized without the intervention of the user, saving time and effort, liberating the hands of the user, and making it cleaner when the user raises a pet.

[0112] In an optional implementation manner of this embodiment, before the water spraying member passes water, it further includes:

[0113] Controlling the inner bin of the cat litter box to be fixed at the standby position and controlling the cat litter scoop to rotate to a state facing the bottom of the inner bin of the cat litter box.

[0114] It should be noted that when the water spraying member and the cat litter shovel are correspondingly arranged, if the cat litter shovel forms an angle with the direction of gravity, that is, the cat litter shovel is inclined or horizontally arranged, the water flow sprayed onto the cat litter shovel will directly flow into the inner bin of the cat litter box due to the action of gravity and cannot flow through the entire surface of the cat litter shovel, thus unable to achieve a complete cleaning of the cat litter shovel. Therefore, before opening the water adding device and spraying water onto the cat litter shovel, the cat litter shovel can be first controlled to rotate to a state facing the bottom of the inner bin of the cat litter box, such as rotating to a vertically downward state. At this time, the water flow sprayed out by the water spraying member can flow down along the surface of the cat litter shovel to clean the entire surface of the cat litter shovel, and the water flow after cleaning the cat litter shovel flows into the inner bin of the cat litter box. In this way, while cleaning the inner bin of the cat litter box, it is ensured that the cat litter shovel can be fully cleaned, and the cleaning of both the cat litter shovel and the inner bin of the cat litter box can be achieved simultaneously, ensuring the cleanliness and hygiene of the intelligent cat litter box and improving the cleaning efficiency.

[0115] In an optional implementation manner of this embodiment, after the water supply ends and the inner bin of the cat litter box is controlled to rotate back and forth a set number of times, it further includes:

[0116] Controlling the inner bin of the cat litter box to stay at the scraping position;

[0117] Controlling the cat litter shovel to rotate a set number of circles.

[0118] It should be noted that the cat litter shovel includes a cat litter shovel main body and a soft rubber scraping strip. The cat litter shovel is in interference contact with the inner bin of the cat litter box through the soft rubber scraping strip. The soft rubber scraping strip is fixed on the cat litter shovel main body by means of encapsulation and abuts against the inner bin of the cat litter box during use. Therefore, the relative rotation of the cat litter shovel and the inner bin of the cat litter box can also be controlled to scrape the inner bin of the cat litter box, and the soft rubber scraping strip can protect the inner bin of the cat litter box during scraping. In addition, the soft rubber scraping strip can have a protruding part, so that the protruding part is in interference fit with the inner bin of the cat litter box to fully scrape the dirt on the inner bin of the cat litter box.

[0119] Specifically, in implementation, the inner bin of the cat litter box can be controlled to stay at the scraping position, then the cat litter shovel is controlled to rotate a set number of circles, and then it returns to the area where it is in standby. This scraping position is the position where the inner bin of the cat litter box stays after rotating left and right a set number of times along the horizontal direction. There is no need to control the inner bin of the cat litter box to rotate anymore, and the cat litter shovel is directly controlled to rotate a set number of circles at the current position to scrape the small particles of dirt remaining on the inner bin of the cat litter box, achieving a full cleaning of the inner bin of the cat litter box and ensuring the cleanliness and hygiene of the inner bin of the cat litter box.

[0120] In an optional implementation manner of this embodiment, after controlling the inner bin of the cat litter box to rotate to the sewage dumping position and dumping the sewage out of the inner bin of the cat litter box, it further includes:

[0121] Controlling the cat litter shovel to rotate at least one circle.

[0122] It should be noted that after controlling the relative rotation between the litter scoop and the inner bin of the litter box and scraping and washing the inner bin of the litter box, although the dirt in the inner bin of the litter box is scraped and washed clean, the sewage generated by the scraping and washing will remain on the surface of the inner bin of the litter box. Therefore, it is also possible to control the inner bin of the litter box to remain stationary and control the litter scoop to rotate at least one full circle to scrape off the residual water stains on the inner bin of the litter box, further cleaning the inner bin of the litter box thoroughly and ensuring the cleanliness and hygiene of the inner bin of the litter box. Among them, the rotation direction can be configured, such as clockwise, counterclockwise, etc.

[0123] For example, control the inner bin of the litter box to be fixed, and the litter scoop rotates 2 circles clockwise, so that the soft rubber scraping strip of the litter scoop scrapes the residual water stains on the surface of the inner bin of the litter box into the sewage tank.

[0124] As an example, Figures 5a - 5g is a schematic diagram of the rotation logic in the water flushing cleaning mode provided by an embodiment of this specification. As Figures 5a - 5g shown, taking the sewage tank being arranged at the lower left side of the inner bin of the litter box as an example for illustration, that is, pouring sewage from the left side of the inner bin of the litter box, and defining the vertical position as the 0° position.

[0125] Before performing water flushing cleaning, first perform waste litter dumping to remove the waste litter in the inner bin of the litter box. After completing the waste litter removal, both the litter scoop and the inner bin of the litter box return to the standby position, as Figure 5a shown. At this time, the inner bin of the litter box is fixed, and the litter scoop rotates clockwise from the fourth quadrant (that is, the area where it is in standby, such as -87°) to the state facing the bottom of the inner bin of the litter box. Preferably, the litter scoop is in a vertically downward state (that is, 0°), as Figure 5b shown. After the litter scoop stops rotating, the water spraying part starts to supply water.

[0126] After the water supply ends, control the inner bin of the litter box to rotate back and forth a set number of times in both forward and reverse directions, and keep the litter scoop in a vertically downward state. In this embodiment, control the inner bin of the litter box to rotate clockwise from 0° to +65°, and then rotate counterclockwise from +65° to -65°, rotating back and forth in both forward and reverse directions multiple times with the same rotation angle, as Figure 5c 、 Figure 5d shown. At this time, the scraping position is the -65° position, so that the inner wall of the inner bin of the litter box can be fully wetted, and the litter scoop also cleans the inner surface when rotating inside the bin. The actual rotation angle back and forth can be adjusted according to the actual water level formed by the water addition amount.

[0127] After that, control the inner bin of the litter box to stop rotating, and control the litter scoop to start rotating clockwise for multiple circles. After completion, the litter scoop returns to the area where it is in standby (such as -87°), as Figure 5eAs shown, this rotation process enables the litter scoop to clean the dirt residues in the inner compartment of the litter box through the soft rubber scraping strip at the bottom. During the above process, the litter box stays at the scraping position. Of course, it can also stay at other positions and then control the litter scoop to rotate multiple times.

[0128] After that, control the litter scoop to stop rotating, and control the inner compartment of the litter box to rotate counterclockwise from the scraping position (such as -65°) to the sewage dumping position (such as -100°), as Figure 5f shown, this rotation process can pour the sewage out of the inner compartment of the litter box and into the sewage tank.

[0129] After that, control the inner compartment of the litter box to stop rotating, and control the litter scoop to rotate clockwise at least 1 circle, as Figure 5g shown, this rotation process can scrape the remaining sewage in the inner compartment of the litter box into the sewage tank, completing the automatic cleaning function.

[0130] It should be noted that the above positions such as -87°, +65°, -65° are for illustrative purposes only. In actual applications, adjustments and configurations can be made according to the specific size and shape of the litter scoop, the size and shape of the inner compartment of the litter box, the installation position between the litter scoop and the inner compartment of the litter box, and the actual scenario requirements. The embodiments of this specification do not limit this.

[0131] In an optional implementation manner of this embodiment, the intelligent litter box further includes a drying device. The drying device is arranged on one side above the inner compartment of the litter box, and the target cleaning mode is the drying mode; control the inner compartment of the litter box to rotate to the target position corresponding to the target cleaning mode to implement the cleaning task in the target cleaning mode, including:

[0132] Control the inner compartment of the litter box to rotate to the drying position, where the drying position is the position that makes the opening of the inner compartment of the litter box face the drying device;

[0133] Control to start the drying device, and dry the inner compartment of the litter box through the wind blown by the drying device;

[0134] After a set time, control to turn off the drying device, and control the inner compartment of the litter box to rotate back to the standby position.

[0135] It should be noted that the intelligent litter box further includes a drying device. The drying device is arranged on one side above the inner compartment of the litter box. By rotating the opening of the inner compartment of the litter box to face the drying device, the inner compartment of the litter box can be dried through the wind blown by the drying device. Preferably, in order to accelerate the drying speed, a heating component can be arranged in the drying device to heat the extracted wind and blow hot air into the inner compartment of the litter box for drying.

[0136] In practical applications, the inner bin of the litter box can be first controlled to rotate to the drying position, which refers to the position where the opening of the inner bin of the litter box faces the drying device; then, the drying device is controlled to start, and the inner bin of the litter box is dried by the air blown out by the drying device. After a set time, the drying device is controlled to turn off, and the inner bin of the litter box is controlled to rotate back to the standby position, completing the automatic drying of the inner bin of the litter box. In this way, through the rotation logic of controlling the inner bin of the litter box to rotate to the drying position - starting the drying device - turning off the drying device - the inner bin of the litter box rotating back to the standby position, drying is automatically achieved without user intervention, saving time and effort, liberating the user's hands, and making it cleaner when the user raises pets.

[0137] It should be noted that generally, after water flushing and cleaning, water stains will remain on the litter scoop and the inner bin of the litter box. Therefore, the drying mode is often executed after the water flushing and cleaning mode, that is to say, the execution logic of the drying mode is to first execute the water flushing and cleaning mode, and then execute the drying mode.

[0138] In an optional implementation manner of this embodiment, in the drying mode, it further includes:

[0139] Controlling the litter scoop to rotate to a set angle to dry the litter scoop by the air blown out by the drying device;

[0140] Correspondingly, after controlling the inner bin of the litter box to rotate back to the standby position, it further includes:

[0141] Controlling the litter scoop to rotate back to the area where it is in standby.

[0142] It should be noted that after controlling the inner bin of the litter box to rotate to the drying position, the litter scoop can also be controlled to rotate to a set angle to dry the litter scoop by the air blown out by the drying device, and then the litter scoop is controlled to rotate back to the area where it is in standby. In this way, the drying device can be used to simultaneously dry the inner bin of the litter box and the litter scoop, improving the drying efficiency.

[0143] As an example, Figures 6a - 6c is a schematic diagram of the rotation logic in the drying mode provided by an embodiment of this specification. As Figures 6a - 6c shown, taking the drying device being arranged above the right side of the inner bin of the litter box as an example for illustration, the vertical position is defined as the 0° position.

[0144] After the automatic cleaning function is completed, the positions of the inner bin of the litter box and the litter scoop are as Figure 6a shown. At this time, the inner bin of the litter box is controlled to rotate counterclockwise from the sewage dumping position (-100°) at the end of the water flushing and cleaning mode to the drying position (+110°), and the litter scoop is controlled to rotate clockwise from the fourth quadrant (returning to the area where it is in standby at the end of the water flushing and cleaning mode, such as -87°) to the set angle (such as +90°), as Figure 6b shown.

[0145] After that, control the drying device to start working. After a period of air drying, the hot air with a certain temperature dries the water stains remaining on the surface of the inner bin of the litter box and the litter scoop. At this time, stop the drying device;

[0146] After that, control the litter box to rotate counterclockwise from the drying position (such as +110°) to the standby position (such as 0°), and control the litter scoop to rotate clockwise from the set angle (such as +90°) to the fourth quadrant (the area where the standby is located, such as -87°). At this time, it returns to the standby position state, as Figure 6c shown. At this time, the automatic drying function is completed.

[0147] It should be noted that the above positions such as +110° and +90° are only for illustrative purposes. In actual applications, adjustments can be made according to the specific size and shape of the litter scoop, the size and shape of the inner bin of the litter box, the installation position between the litter scoop and the inner bin of the litter box, and the actual scenario requirements. The embodiments of this specification do not limit this.

[0148] In the cleaning control method of the intelligent litter box provided in the embodiments of this specification, the intelligent litter box includes a rotatable litter scoop and an inner bin of the litter box. The intelligent litter box supports multiple cleaning modes such as the dirty waste removal mode, the waste sand emptying mode, the water flushing cleaning mode, and the drying mode. By controlling the litter scoop to rotate to the target area corresponding to the corresponding cleaning mode and controlling the inner bin of the litter box to rotate to the target position corresponding to the corresponding cleaning mode, the cleaning tasks under the corresponding cleaning mode can be realized. In this way, by driving the litter scoop and the inner bin of the litter box to rotate respectively by two motors, through different rotation logics, the litter scoop and the inner bin of the litter box are rotated to different positions, and in cooperation with the water spraying part and the drying device, multiple cleaning modes can be realized, automatically and efficiently cleaning the litter box, realizing multiple functions of the intelligent litter box with a very small number of parts, making the functions of the intelligent litter box more diverse and more concentrated, without the need for user intervention, automatically controlling the rotation of the litter scoop and the inner bin of the litter box to realize the cleaning of the intelligent litter box, saving time and effort, liberating the user's hands, making it cleaner and more hygienic when the user raises a pet, being able to better protect the health of the cat and improve the user experience, and the intelligent litter box is easy to operate and store and can be set according to the user's needs.

[0149] Corresponding to the above method embodiments, this specification also provides an embodiment of an intelligent litter box, Figure 7 showing a schematic structural diagram of an intelligent litter box provided by an embodiment of this specification. As Figure 7As shown in the figure, the intelligent cat litter box includes an inner bin 1 of the cat litter box, a main body 2 of the cat litter shovel, a water spraying member 3, a nozzle cover plate 4, a drying device 5, and a screw 6. The inner bin 1 of the cat litter box is coaxially assembled with the main body 2 of the cat litter shovel and is driven by different motors. The water spraying member 3 is installed inside the main body 2 of the cat litter shovel and is fixed by the nozzle cover plate 4. The nozzle cover plate 4 is fixed on the main body 2 of the cat litter shovel by the screw 6. The drying device 5 is located at the upper right of the inner bin of the cat litter box, and the assembly relationship is as Figure 8 and Figure 9 shown in the figure.

[0150] Among them, the main body of the cat litter shovel includes a plurality of support structures, and the plurality of support structures are arranged at intervals along the extending direction of the main body of the cat litter shovel. The intervals between the plurality of support structures of the main body of the cat litter shovel are used to filter out clean cat litter.

[0151] It should be noted that the main body of the cat litter shovel includes a plurality of support structures, and the plurality of support structures are arranged at intervals along the extending direction of the cat litter shovel. That is to say, the main body of the cat litter shovel is a structure similar to a guardrail. The dirt is blocked by the support structures, and the clean cat litter can be separated from the intervals between adjacent support structures and left in the inner bin of the cat litter box for continued use, realizing the separation of clean cat litter and saving cat litter.

[0152] Specifically, the distribution of the plurality of support structures is dense in the middle and wide on both sides. That is to say, the gap between the support structures on both sides of the main body of the cat litter shovel is large, and the gap between the support structures in the middle is small.

[0153] It should be noted that during the process of shoveling the cat litter, the piled-up cat litter shoveled by the cat litter shovel will flow out to both sides of the cat litter shovel. Therefore, the gaps between the support structures on both sides are set wider to facilitate the clean cat litter to leak out from the cat litter shovel, while the small gap in the middle area can ensure that the clumped dirt will not leak out when shoveled.

[0154] In addition, the cross-section of the support structure is configured to be thin at the front end, wide in the middle, and thin at the rear end.

[0155] It should be noted that the wide middle of the support structure can better block the shoveled dirt, while the thin front end and thin rear end structures can better facilitate the clean cat litter to flow out and stay in the inner bin of the cat litter box to achieve the filtration of clean cat litter.

[0156] Furthermore, in addition to the litter scoop main body, the litter scoop can also include a soft rubber scraping strip, which is fixed to the litter scoop main body in a way of rubber coating. When in use, the soft rubber scraping strip abuts against the inner bin of the litter box. In this way, the two sides of the bottom edge of the litter scoop can be reused. One side is set as a hard scraping corner to remove dirt, and the other side is set as a soft rubber scraping strip through rubber coating to protect the surface of the inner bin of the litter box. Secondly, the soft rubber scraping strip has a protrusion, and the protrusion is in interference fit with the inner bin of the litter box to scrape and wash the dirt in the inner bin of the litter box; there is a set scraping angle between the bottom of the litter scoop main body and the inner bin of the litter box. When the litter scoop main body shovels up the dirt at the bottom, the litter scoop main body and the dirt form an obtuse angle relationship, which can effectively shovel up the dirt sticking to the bottom; the gap between the bottom of the litter scoop main body and the inner bin of the litter box is small at the front end and large at the rear end, effectively reducing the rolling situation caused by the litter entering the gap between the bottom of the litter scoop main body and the inner bin of the litter scoop, and at the same time reducing the friction between the litter scoop main body and the inner bin of the litter scoop.

[0157] In actual implementation, the water spraying member includes a plurality of vertical water distributing nozzles. One supporting structure corresponds to at least one vertical water distributing nozzle. Through the plurality of vertical water distributing nozzles, water flow can be sprayed onto the supporting structure to achieve water spraying and cleaning of the supporting structure. In addition, the water spraying member further includes at least one horizontal water distributing nozzle, and the horizontal water distributing nozzle is used to spray water on the side wall of the inner bin of the litter box to clean the side wall of the inner bin of the litter box.

[0158] The water passing structure of the water spraying member is to introduce water from the water inlet at the top, pass through the internal flow channel, and flow out from the water outlet of the vertical water distributing nozzles at the bottom. The internal flow channel adopts a layered partition structure. The layered partition structure divides the single incoming water flow into multiple strands and evenly flows out from the water outlets of each vertical water distributing nozzle.

[0159] Of course, in addition to fixing the water spraying member inside the litter scoop main body in the above solution, the water spraying member can also be fixed to the outside of the litter scoop main body through screws. The water outlet of the water spraying member is located on the front outer wall of the litter scoop main body. And a baffle can be arranged below the water outlet of the water spraying member. The baffle is used to form a water storage tank below the water outlet of the water spraying member, and the water flow flows to the front outer wall of the litter scoop main body through the water storage tank.

[0160] In the embodiments of this specification, an intelligent cat litter box is provided. This intelligent cat litter box supports multiple cleaning modes such as a dirty waste removal mode, a waste sand dumping mode, a water flushing and cleaning mode, and a drying mode. By using two motors to drive the cat litter shovel and the inner bin of the cat litter box to rotate respectively, and using different rotation logics, the cat litter shovel and the inner bin of the cat litter box can be rotated to different positions. Cooperating with a water spraying part and a drying device, multiple cleaning modes can be realized to automatically and efficiently clean the cat litter box. With a very small number of parts, multiple functions of the intelligent cat litter box can be achieved, making the functions of the intelligent cat litter box more diverse and more concentrated. Without user intervention, the rotation of the cat litter shovel and the inner bin of the cat litter box is automatically controlled to clean the intelligent cat litter box, saving time and effort, liberating the user's hands, making it cleaner and more hygienic when the user raises a pet, being able to better ensure the health of the cat and improve the user experience. Moreover, this intelligent cat litter box is easy to operate and store, and can be set according to the user's needs.
