Description

Technical Field

[0001] This invention relates to the field of intelligent cat litter box technology, and specifically to a control system and method for an intelligent cat litter box. Background Technology

[0002] As living standards improve, more and more people are choosing to keep cats, and litter boxes are an essential item for cat owners. With the development of the cat industry, smart litter boxes have begun to emerge to free up owners' hands. In the existing smart litter boxes, automatic waste removal is generally achieved by using a rotating ball chamber in conjunction with a filter to separate cat litter from cat litter, such as the smart litter box with patent application number CN202311027921.2.

[0003] The following problems still exist during the operation and use of the aforementioned smart litter box:

[0004] (1) When the ball chamber rotates to clean the cat litter, this type of smart cat litter box generally resets at a fixed point. Since the curved surface of the collection chamber is fitted to the inner wall of the ball chamber, when cleaning and changing the litter, some cat litter clumps will still flow out of the collection chamber after the ball chamber is reset and leveled.

[0005] (2) After the cat litter in the ball chamber is replaced and emptied, the surface of the cat litter in this type of smart litter box will be uneven, which will not provide a good environment when the cat defecates.

[0006] Therefore, this application proposes a control method for an intelligent cat litter box to solve the above-mentioned technical problems. Summary of the Invention

[0007] The main objective of this invention is to provide a control system and method for an intelligent litter box that can achieve relatively accurate rotational self-check and repositioning when the litter ball compartment is reset, and can level the surface of the litter after the litter has been replaced and emptied.

[0008] The present invention solves the above-mentioned technical problems by adopting the following technical solutions:

[0009] A control system for an intelligent cat litter box is used to control the rotation of the litter box body above a base. The base has a mounting plate for limiting the mounting of the litter box body. The control system includes:

[0010] The Hall positioning component, based on the Hall effect sensor set on the mounting plate, is used to sense the magnetic component on the main body of the sphere. The Hall positioning component and the magnetic component cooperate with each other to position the main body of the sphere in a flat state and emit corresponding sensing signals.

[0011] Rotation control assembly, used to control the rotation of the main body of the sphere compartment on the mounting plate;

[0012] The controller receives the sensing signals from the Hall positioning component and the magnet component, and operates the rotation control component to complete the cat litter cleaning, cat litter replacement, self-check of the ball chamber body leveling, and cat litter leveling operations.

[0013] Preferably, a fecal collection chamber body is provided inside the ball chamber body, and one side of the fecal collection chamber body is connected to the interior of the ball chamber body through a fecal collection chamber door, and the other side of the ball chamber body corresponding to the fecal collection chamber door is connected to the interior of the ball chamber body and is provided with a filter screen;

[0014] As the ball chamber body rotates counterclockwise above the base, the waste collection compartment door opens to allow cat litter to enter the ball chamber body.

[0015] Preferably, the controller internally includes a litter cleaning module, a litter changing module, a ball pit self-checking module, and a ball pit leveling module, wherein:

[0016] The litter cleaning module is used to control the main body of the litter box to rotate counterclockwise until the waste collection chamber door opens, and then control the main body of the litter box to rotate clockwise back to its original position after the waste collection chamber door opens.

[0017] The cat litter changing module is used to control the rotation of the ball chamber body through the rotation control component to change the cat litter inside the ball chamber body;

[0018] The ball tank self-inspection module is used to perform a self-inspection of the ball tank body's flatness by controlling the rotation of the ball tank body through the rotation control component;

[0019] The litter bin leveling module is used to control the rotation of the litter bin body through a rotation control component to level the cat litter inside the litter bin body.

[0020] Preferably, a control method for an intelligent litter box is based on the control system of any of the intelligent litter boxes described above. The control component is used to control the rotation of the ball chamber body to perform litter cleaning, litter replacement, self-checking of the ball chamber body's flatness, and litter flatness operation.

[0021] Preferably, the magnet assembly is disposed on the side of the ball compartment body near the mounting plate, and includes a magnet at point a and a magnet at point b;

[0022] The Hall positioning component includes Hall A point and Hall B point, which are used to further sense the rotational attitude of the sphere by sensing the positions of magnetic a point and magnetic b point, and send sensing signals to the controller;

[0023] When the main body of the sphere is flat, magnetic point a is in conjunction with sensor point A, and magnetic point b is in conjunction with sensor point B.

[0024] Preferably, the cat litter cleaning includes the following specific steps:

[0025] L1. Use the rotation control component to drive the ball chamber to rotate counterclockwise until the waste collection chamber door and filter screen open;

[0026] L2. The ball chamber is driven to rotate clockwise using a rotation control component;

[0027] L3. When Hall A point passes through magnetic a point at a rotation angle of 0° to 210°, the cat litter inside the ball chamber body, in conjunction with gravity, controls the ball chamber body to rotate above the base. The ball chamber body rotates to the sensing position of Hall A point and magnetic a point to complete the cat litter cleaning.

[0028] Preferably, the cat litter changing includes the following specific steps:

[0029] S1. Use the rotation control component (3) to drive the ball chamber to rotate clockwise to Hall point A (41) to complete one sand cleaning operation;

[0030] S2. Use the rotation control component (3) to drive the ball chamber to rotate counterclockwise by a specified angle, and then drive the ball chamber to rotate clockwise again to the sensing position of Hall A point (41) and magnetic a point (51) to complete one residual sand collection operation;

[0031] S3. Determine if there is residual sand inside the ball chamber. If so, repeat step S2.

[0032] S4. Finally, the rotation control component is used to drive the main body of the hopper to rotate clockwise on the base to the bag changing angle, so that the user can take and change the garbage bag at the bag opening inside the hopper within a preset time. After the preset time is over, the hopper body is driven to rotate clockwise back to the flat position.

[0033] Preferably, the self-inspection of the flatness of the main body of the sphere compartment includes the following specific operating steps:

[0034] Step 1: The Hall effect positioning component and the magnet component are used to further sense the rotational attitude of the main body of the sphere.

[0035] Step 2: If Hall point A and magnetic point a are mutually induced or Hall point B and magnetic point b are mutually induced, the ball chamber body is directly rotated by the rotation control component to perform the leveling operation of the cat litter inside the ball chamber body.

[0036] Step 3: If Hall A cannot sense magnetic point a or Hall B cannot sense magnetic point b, use the rotation control component to drive the ball chamber body to rotate on the base until Hall A senses magnetic point a or Hall B senses magnetic point b, and control the ball chamber body to rotate to the position where Hall A and magnetic point a sense each other or Hall B and magnetic point b sense each other.

[0037] Preferably, during the execution of the control method, if the positions of the magnetic points a and b cannot be confirmed by the Hall A and Hall B points, the rotation control component stops operating, and the controller is used to send an alarm signal to the outside.

[0038] This invention provides a control method for an intelligent cat litter box. Compared with existing technologies, the advantages of this invention are as follows:

[0039] 1. This invention further senses and controls the rotation angle of the litter box body on the mounting plate by setting a Hall positioning component and a positioning magnet component. It can sense and emit corresponding sensing signals in a timely manner when the litter box body rotates to a specified rotation posture, which facilitates the subsequent use of rotation control components to accurately control the rotation of the litter box body to change posture, and complete the cleaning, leveling, litter changing, and self-inspection operations of the litter box body.

[0040] 2. During the sand-changing process, this invention uses a rotation control component to drive the main body of the ball chamber to rotate clockwise to Hall point A to complete one sand-cleaning operation. By driving the main body of the ball chamber to rotate counterclockwise by a specified angle, and then driving the ball chamber to rotate clockwise again to the Hall point A and magnetic point a sensing position, one residual sand collection operation is completed. This operation can be repeated multiple times to improve the quality of residual sand collection. Afterwards, the main body of the ball chamber is driven to rotate clockwise to the bag-changing angle for easy replacement of garbage bags. This invention can efficiently and quickly collect residual sand and replace garbage bags after the sand-cleaning operation, making it convenient to use.

[0041] 3. During the self-checking operation, this invention uses a rotation control component to control the rotation of the ball chamber body and a Hall positioning component to sense the position of the magnet component. This allows the ball chamber body to achieve a more accurate rotation self-check and return to its original position, avoiding the ball chamber body's posture from deviating under normal conditions after repeated use, thus improving the quality of use of this type of smart litter box.

[0042] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] In the first embodiment, see details below. Figures 1 to 6 .

[0055] like Figures 2 to 4 As shown, the present invention provides a control method for an intelligent cat litter box. The control system controls the ball chamber body 1 to rotate above the base 2. The base 2 is provided with an mounting plate 21 for limiting the installation of the ball chamber body 1.

[0056] The ball chamber body 1 has an opening 11, which allows the cat to enter and exit while facilitating the replacement of cat litter. The opening 11 is located in the middle of the ball chamber body 1, which ensures that the cat litter inside the ball chamber body 1 will not overflow when the ball chamber body 1 is rotating.

[0057] The control system includes:

[0058] The Hall positioning component 4, based on the Hall effect sensor set on the mounting plate 21, is used to sense the magnet component 5 on the ball chamber body 1. The Hall positioning component 4 and the magnet component 5 cooperate with each other to position the ball chamber body 1 in a flat state and emit corresponding sensing signals.

[0059] Rotation control component 3 is used to control the rotation of the ball tank body 1 on the mounting plate 21;

[0060] The controller 6 is used to receive the sensing signals from the Hall positioning component 4 and the magnet component 5, and to operate the rotation control component 3 to complete the cat litter cleaning, cat litter replacement, self-checking of the ball chamber body 1, and cat litter leveling operation.

[0061] In practice, the Hall positioning component 4 senses the positioning magnet component 5 to further sense and control the rotation angle of the ball chamber body 1 on the mounting plate 21. It can sense and emit corresponding sensing signals in a timely manner when the ball chamber body 1 rotates to the specified rotation posture, so that the rotation control component 3 can accurately control the rotation of the ball chamber body 1 to change its posture and complete the cleaning, leveling, litter changing and self-inspection operations of the cat litter box ball chamber body 1.

[0062] It should be noted that, based on the existing patent cited in the background art (a smart cat litter box with patent application number CN202311027921.2), the overall structure of a smart cat litter box has already been described, so the overall structure of the smart cat litter box in this application will not be described again.

[0063] In further use, according to the existing patent cited, the main body 1 of the ball chamber is provided with a fecal collection chamber body 14, and one side of the fecal collection chamber body 14 is connected to the inside of the ball chamber body 1 through the fecal collection chamber door 12. The other side of the inside of the ball chamber body 1 is connected to the inside of the ball chamber body 1 and is provided with a filter screen 13.

[0064] As the ball chamber body 1 rotates counterclockwise above the base 2, the waste collection door 12 opens to allow cat litter to enter the ball chamber body 1.

[0065] Further as Figure 1 As shown, the controller 6 internally includes a litter cleaning module 61, a litter changing module 62, a ball chamber self-test module 63, and a ball chamber leveling module 64, wherein:

[0066] The litter cleaning module 61 is used to control the ball chamber body 1 to rotate counterclockwise through the rotation control component 3 until the waste collection chamber door 12 opens, and then control the ball chamber body 1 to rotate clockwise back to its original position after the waste collection chamber door 12 opens.

[0067] The cat litter changing module 62 is used to control the rotation of the ball chamber body 1 through the rotation control component 3 to perform the cat litter changing operation inside the ball chamber body 1;

[0068] The ball tank self-inspection module 63 is used to control the rotation of the ball tank body 1 through the rotation control component 3 to perform a leveling self-inspection operation on the ball tank body 1.

[0069] The litter box leveling module 64 is used to control the rotation of the litter box body 1 through the rotation control component 3 to perform the leveling operation of the cat litter inside the litter box body 1.

[0070] For details in the second embodiment, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 7 .

[0071] Furthermore, the present invention also provides a control method for an intelligent litter box. Based on the control system of the intelligent litter box in the first embodiment, the ball chamber body 1 can be rotated by the rotation control component 3 to perform litter cleaning, litter replacement, self-checking of the ball chamber body 1, and litter leveling operations. Specifically, the rotation control component 3 is used to drive the ball chamber body 1 to perform litter replacement and self-checking operations, and the litter replacement and self-checking operations are respectively driven by the litter replacement module 62 and the ball chamber self-checking module 63.

[0072] It should be noted here that the reference is... Figure 5 and Figure 6 The magnet assembly 5 is located on the side of the ball compartment body 1 near the mounting plate 21, and includes a magnet at point a 51 and a magnet at point b 52.

[0073] The Hall positioning component 4 includes Hall A point 41 and Hall B point 42, which are used to further sense the rotational attitude of the sphere by sensing the positions of magnetic a point 51 and magnetic b point 52, and send sensing signals to the controller 6.

[0074] Furthermore, when the main body 1 of the sphere is flat, magnetic point a 51 is in conjunction with sensor point A 41, and magnetic point b 52 is in conjunction with sensor point B 42.

[0075] Therefore, the specific steps for performing litter cleaning in further methods include:

[0076] L1. Use the rotation control component 3 to drive the ball chamber to rotate counterclockwise until the waste collection chamber door 12 and filter screen 13 open;

[0077] L2. Use rotation control component 3 to drive the ball chamber to rotate clockwise;

[0078] L3. When Hall A point 41 passes through magnetic a point 51 and rotates at an angle of 0° to 210°, the cat litter inside the ball chamber body 1, in conjunction with gravity, controls the ball chamber body 1 to rotate above the base 2. The ball chamber body 1 rotates to the sensing position of Hall A point 41 and magnetic a point 51 to complete the cat litter cleaning.

[0079] The L3 step can be specifically divided into:

[0080] (1) When using mixed sand, rotate 0 to 75 degrees, then rotate back 45 degrees, and then rotate counterclockwise to 210 degrees.

[0081] (2) When using mineral sand, rotate counterclockwise directly from 0 to 210 degrees.

[0082] It should be noted that the rotation angle of the main body 1 of the ball chamber can be adjusted according to the actual application mode:

[0083] Soft stool mode: Before cleaning, rotate the stool back and forth twice between -45 degrees and 45 degrees, and then clean it.

[0084] Deep mode: Performs two cleanups directly.

[0085] Therefore, as Figure 7 As shown, the specific steps for performing cat litter changing in a further method include:

[0086] S1. Use the rotation control component (3) to drive the ball chamber to rotate clockwise to Hall point A (41) to complete one sand cleaning operation;

[0087] S2. Use the rotation control component (3) to drive the ball chamber to rotate counterclockwise by a specified angle, and then drive the ball chamber to rotate clockwise again to the sensing position of Hall A point (41) and magnetic a point (51) to complete one residual sand collection operation;

[0088] S3. Determine if there is residual sand inside the ball chamber. If so, repeat step S2.

[0089] S4. Finally, the rotation control component 3 is used to drive the main body 1 of the ball compartment to rotate clockwise on the base 2 to the bag changing angle, so that the user can take and change the garbage bag at the bag opening inside the main body 1 of the ball compartment within a preset time, and after the preset time ends, the main body 1 of the ball compartment is driven to rotate clockwise back to the flat position.

[0090] It should be noted that in step S3, the determination of whether there is residual sand inside the ball chamber is generally made by visual inspection. Alternatively, a corresponding sensor can be installed inside the ball chamber to sense the amount of residual sand inside the ball chamber.

[0091] It should also be further explained that, unlike the existing smart litter boxes, which generally require an additional baffle for litter changing, and where the litter chamber rotates in the same direction as the cleaning mechanism, this application uses a method where the cleaning mechanism rotates counterclockwise from 0 to 210 degrees, while the litter chamber rotates clockwise from 0 to 300 degrees. This simplifies the overall structure for litter changing and improves the overall litter changing effect and quality.

[0092] During the sand replacement process, the rotation control component 3 drives the main body 1 of the ball chamber to rotate clockwise to Hall point A 41 to complete one sand cleaning operation. By driving the main body 1 of the ball chamber to rotate counterclockwise by a specified angle, and then driving the ball chamber to rotate clockwise again to the Hall point A 41 and the magnetic point a 51 sensing position, one residual sand collection operation is completed. This operation can be repeated multiple times to improve the quality of residual sand collection. Afterwards, the main body 1 of the ball chamber is driven to rotate clockwise to the bag changing angle for easy replacement of garbage bags. This allows for efficient, high-quality, and rapid collection of residual sand and replacement of garbage bags after the sand cleaning operation, making it convenient to use.

[0093] In addition, such as Figure 7 As shown, in the further method of performing the self-inspection operation on the leveling of the main body 1 of the sphere compartment, the specific steps include:

[0094] Step 1: The rotational attitude of the main body 1 of the ball chamber is further sensed by the Hall positioning component 4 and the sensing magnet component 5;

[0095] Step 2: If Hall A point 41 and magnetic a point 51 are mutually induced or Hall B point 42 and magnetic b point 52 are mutually induced, the ball chamber body 1 is directly controlled to rotate by the rotation control component 3 to perform the leveling operation of the cat litter inside the ball chamber body 1.

[0096] Step 3: If Hall A point 41 cannot sense magnetic point a 51 or Hall B point 42 cannot sense magnetic point b 52, use the rotation control component 3 to drive the ball chamber body 1 to rotate on the base 2 until Hall A point 41 senses magnetic point a 51 or Hall B point 42 senses magnetic point b 52, and control the ball chamber body 1 to rotate to the position where Hall A point 41 and magnetic point a 51 sense each other or Hall B point 42 and magnetic point b 52 sense each other.

[0097] In step three, if Hall A point 41 cannot sense the position of magnetic a point 51 and Hall B point 42 also cannot sense the position of magnetic b point 52, then the rotation control component 3 stops operating, and the controller 6 is used to send an alarm signal to the outside.

[0098] At this time, because the rotation control component 3 controls the rotation of the ball chamber body 1 during the leveling self-check operation, and the position of the magnet component 5 is sensed by the Hall positioning component 4, the ball chamber body 1 can easily achieve a more accurate rotation self-check and return to its original position. This avoids the ball chamber body 1 from deflecting under normal conditions after repeated use, thus improving the quality of use of this type of smart litter box.

[0099] In addition, it should be noted that during the execution of the control method of the smart litter box, if Hall A point 41 and Hall B point 42 cannot confirm the position of magnetic a point 51 and magnetic b point 52, the rotation control component 3 will stop operating, and the controller 6 will be used to send an alarm signal.

[0100] At this point, we can explain further that, due to the external wear and stress on the main body 1 of the litter box during rotation, there is a certain offset of the center point. Therefore, during the actual rotation of the main body 1 of the litter box, the positions of Hall A point 41 and Hall B point 42 cannot be confirmed by magnetic a point 51 and magnetic b point 52. It can generally be determined that the main body 1 of the litter box of the cat litter box needs to be repaired.

[0101] In the third embodiment.

[0102] Based on the above embodiments, the overall operation method of the smart litter box can be further described, specifically including the following operation steps:

[0103] (1) After the smart litter box device is powered on, it performs a self-check operation to level the ball chamber body 1. During the self-check operation, if an object is detected to be close to the front of the device at an angle of 15 degrees upward and the distance is between 8 and 15 cm, the ball chamber body 1 is controlled to stop the self-check operation and the smart litter box light component emits a red flashing light. After the object leaves for 10 seconds, the self-check operation continues. After the self-check operation is completed, the device enters the standby state and the smart litter box light component emits a white light that stays on.

[0104] (2) The user drives the cat litter changing module 62 in the controller 6 through an external app or local terminal. The smart cat litter box device is turned on to perform cat litter changing operation. During the cat litter changing operation, the motor current is detected. If it exceeds the rated current by 20%, the drive motor of the rotation control component 3 stops.

[0105] Meanwhile, within 10 seconds of the smart litter box device pausing, the user can reset the ball chamber body 1 by driving the rotation control component 3 through the external app or local terminal. If the user continues to drive the litter changing module 62 in the controller 6 through the external app or local terminal within 10 seconds of the smart litter box device pausing, the smart litter box device will continue to perform the litter changing operation.

[0106] (3) Users can set a do-not-disturb period in the smart litter box control system through an external app or local terminal. During this period, the smart litter box device will not perform any operation.

[0107] (4) If the user inputs that the cat's weight is less than 800g, the smart litter box device will not use the litter cleaning module 61 by default, and the user can manually clean the litter box.

[0108] (5) If the user sets the soft poop mode in the intelligent litter box control system through an external app or local terminal, the intelligent litter box device will first drive the ball chamber leveling module 64 to operate before driving the litter cleaning module 61.

[0109] (6) If the user sets the depth mode in the intelligent litter box control system through an external app or local terminal, the intelligent litter box device will drive the litter cleaning module 61 in the controller 6 to run twice by default, and drive the litter box leveling module 64 to run after the main body of the ball chamber 1 returns to the origin 53.

[0110] (7) The user drives the ball chamber leveling module 64 in the controller 6 through the external app or local terminal. During the leveling process of the ball chamber body 1, if an object approaches the front of the device at an angle of 15 degrees upward and the distance is 8 to 15 cm, the leveling stops and the smart cat litter box light component emits red light flashing. After the object leaves for 10 seconds, the self-check continues.

[0111] The controller 6 of the aforementioned built-in control system consists of a memory and a processor.

[0112] The memory may include random access memory (RAM) or non-volatile memory (NVM), such as at least one disk storage device. Optionally, the memory may also be at least one storage device located remotely from the aforementioned processor.

Rotation control assembly (3) is used to control the rotation of the ball tank body (1) on the mounting plate (21); The controller (6) is used to receive the sensing signals of the Hall positioning component (4) and the magnet component (5), and to operate the rotation control component (3) to complete the cat litter cleaning, cat litter replacement, ball chamber body (1) leveling self-inspection and cat litter leveling operation; The controller (6) is equipped with a ball compartment self-test module (63), which is used to perform a flat self-test operation of the ball compartment body (1) by controlling the rotation of the rotation control component (3) to rotate the ball compartment body (1). The magnet assembly (5) is located on the side of the ball compartment body (1) near the mounting plate (21), and includes a magnet at point a (51) and a magnet at point b (52); The Hall positioning component (4) includes Hall A point (41) and Hall B point (42), which are used to further sense the rotational attitude of the sphere by sensing the positions of magnetic a point (51) and magnetic b point (52), and send sensing signals to the controller (6); When the main body (1) of the sphere is in a flat state, the magnetic point a (51) is in conjunction with the sensing Hall point A (41), and the magnetic point b (52) is in conjunction with the sensing Hall point B (42). The self-inspection of the flatness of the main body (1) of the ball tank includes the following specific operating steps: Step 1: The Hall positioning component (4) senses the magnet component (5) to further sense the rotational attitude of the main body (1) of the ball chamber; Step 2: If Hall point A (41) and magnetic point a (51) are mutually induced or Hall point B (42) and magnetic point b (52) are mutually induced, the ball chamber body (1) is directly controlled to rotate by the rotation control component (3) to perform the leveling operation of the cat litter inside the ball chamber body (1); Step 3: If Hall A point (41) cannot sense magnetic a point (51) or Hall B point (42) cannot sense magnetic b point (52), use the rotation control component (3) to drive the ball chamber body (1) to rotate on the base (2) until Hall A point (41) senses magnetic a point (51) or Hall B point (42) senses magnetic b point (52), and control the ball chamber body (1) to rotate to the position where Hall A point (41) and magnetic a point (51) sense each other or Hall B point (42) and magnetic b point (52) sense each other.

2. The control method for the intelligent litter box as described in claim 1, characterized in that, The cat litter cleaning process includes the following specific steps: L1. Use the rotation control component (3) to drive the ball chamber to rotate counterclockwise until the stool collection chamber door (12) and filter screen (13) open; L2. Use the rotation control component (3) to drive the ball chamber to rotate clockwise; L3. When the Hall A point (41) passes the magnetic a point (51) at a rotation angle of 0° to 210°, the cat litter inside the ball chamber body (1) is controlled by gravity to rotate the ball chamber body (1) above the base (2). The ball chamber body (1) rotates to the sensing position of the Hall A point (41) and the magnetic a point (51) to complete the cat litter cleaning.

Use the rotation control component (3) to drive the ball chamber to rotate clockwise to Hall point A (41) to complete one sand cleaning operation; S2. Use the rotation control component (3) to drive the ball chamber to rotate counterclockwise by a specified angle, and then drive the ball chamber to rotate clockwise again to the sensing position of Hall A point (41) and magnetic a point (51) to complete one residual sand collection operation; S3. Determine if there is residual sand inside the ball chamber. If so, repeat step S2. S4. Finally, use the rotation control component (3) to drive the main body (1) of the ball compartment to rotate clockwise on the base (2) to the bag changing angle, so that the user can take and change the garbage bag at the bag opening inside the main body (1) within a preset time, and drive the main body (1) of the ball compartment to rotate clockwise back to the flat position after the preset time ends.
