DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an intelligent pet toilet, comprising: a support 1, a bin body 2 is rotatably provided on the support 1, a driving assembly is provided on the support 1, and the driving assembly is used to drive the bin body 2 to rotate on the support 1; a sewage outlet 9 is opened on the arc-shaped side wall of the bin body 2 (according to Figure 3 , Figure 4 As shown, the sewage outlet 9 is located at the top left side of the bin body 2), and a discharge outlet 6 is provided at the bottom of the support 1; a photoelectric sensor 8 and a controller 21 (such as a PLC controller microcontroller) are provided on the support 1, and the photoelectric sensor 8 includes a transmitting end and a detecting end, and the transmitting end and the detecting end are respectively located on both sides of the bin body 2 (according to Figure 3 As shown, the transmitting end and the detecting end are respectively located at the front and rear sides of the warehouse body 2, and a plurality of openings 5 ​​are provided on the two side walls of the warehouse body 2. The openings 5 ​​are used for allowing the light beam emitted by the transmitting end to pass through the warehouse body 2 and illuminate the detecting end. During the rotation of the warehouse body 2, the plurality of openings 5 ​​pass through the photoelectric sensor 8 in turn.

[0035] It should be noted that there are four openings 5, and the four openings 5 ​​are marked as the first opening, the second opening, the third opening and the fourth opening in the clockwise direction (the clockwise direction is Figure 1 and Figure 3), the first opening, the second opening and the third opening are all located below the side wall of the warehouse body 2, and the first opening is located on the right side of the second opening, the third opening is located on the left side of the second opening, and the fourth opening is located above the side wall of the warehouse body 2 and close to the sewage outlet 9; when the warehouse body 2 is straightened, the photoelectric sensor 8 corresponds to the second opening; when the pet enters the warehouse body 2 to go to the toilet, it will block the light beam from the transmitting end to the detection end, and the controller 21 receives the information that the pet has entered the warehouse body 2. When the pet moves out of the warehouse body 2, the light beam from the transmitting end is re-irradiated to the detection end through the second opening. At this time, the controller 21 will control the driving component to work and drive the warehouse body 2 to rotate counterclockwise; at this time, the transmitting end and the second opening are staggered. , the light beam emitted by the transmitting end is blocked by the side wall of the bin body 2 until the transmitting end is aligned with the fourth opening (the third opening serves as a transition effect). At this time, the light beam from the transmitting end is irradiated onto the detection end through the fourth opening. After receiving the information, the controller 21 controls the driving component to stop working and stops the bin body 2 from rotating; at this time, the sewage outlet 9 is aligned downward with the discharge outlet 6, so that the feces inside the bin body is discharged through the sewage outlet 9 and the discharge outlet 6 under the action of gravity; after the bin body 2 stays for a preset time (generally 3 seconds), the controller 21 then controls the driving component to move the bin body 2 in the opposite direction (clockwise rotation), and after the transmitting end is aligned with the second opening, the controller 21 controls the driving component to stop working and reset the bin body 2.

[0036] It should also be noted that the support 1 can be placed directly on the toilet so that the feces discharged from the discharge port 6 directly falls into the toilet; and the support 1 can be placed above other collection devices to collect the feces discharged from the discharge port 6 using the collection device.

[0037] In this embodiment, as a further optimized solution, please refer to Figure 1 and Figure 3 A water supply assembly 3 is connected to the warehouse body 2, and the water supply assembly 3 includes a water supply pipe and a solenoid valve arranged on the water supply pipe, and the water supply pipe is connected to an external water supply device; when cat litter is not loaded inside the warehouse body 2 (at this time, the pet toilet can also be used as a dog toilet), when the pet finishes using the toilet inside the warehouse body 2, the warehouse body 2 rotates, so that the feces are discharged from the warehouse body 2 through the sewage outlet 9. The feces will block the light beam emitted by the transmitting end passing through the opening 5 here, so that the feces can be detected when passing through the sewage outlet 9 of the warehouse body 2. At this time, the controller 21 will control the solenoid valve to open, and supply water to the inside of the warehouse body 2 through the water supply pipe, which is used to flush the inside of the warehouse body 2, and is suitable for pet toilets without cat litter.

[0038] In this embodiment, as a further optimized solution, please refer to Figure 4 , Figure 5 and Figure 6A partition 11 is installed in the inner cavity of the bin body 2, and the partition 11 is L-shaped. The partition 11 divides the inner cavity of the bin body 2 into a garbage cavity 201 and a discharge cavity 202. The garbage cavity 201 and the discharge cavity 202 are distributed up and down. The garbage cavity 201 is connected with the sewage outlet 9. A filter screen 12 is provided in the inner cavity of the discharge cavity 202. The filter screen 12 divides the inner cavity of the discharge cavity 202 into a placement cavity 2021 and a temporary storage cavity 2022. The placement cavity 2021 is located outside the temporary storage cavity 2022 (according to Figure 4 As shown, the placement chamber 2021 is located on the right side of the temporary storage chamber 2022), the temporary storage chamber 2022 is located below the garbage chamber 201, and cat litter is installed inside the placement chamber 2021. An opening 14 is provided on the side wall of the partition 11, and the placement chamber 2021 is connected with the garbage chamber 201 through the opening 14; when the cat finishes using the toilet inside the placement chamber 2021, the warehouse body 2 rotates counterclockwise, so that the cat litter passes through the filter screen 12 and enters the temporary storage chamber 2022 for temporary storage, while the feces is blocked by the filter screen 12. As the warehouse body 2 continues to rotate, so that the sewage outlet 9 faces downward (at this time, the partition 11 restricts the cat litter inside the temporary storage chamber 2022), the feces enters the interior of the garbage chamber 201 from the opening 14, and is then discharged from the sewage outlet 9 and the discharge port 6; after the warehouse body 2 is reset, the cat litter flows back from the temporary storage chamber 2022 to the inner cavity of the placement chamber 2021.

[0039] It should be noted that the left side wall of the bin body 2 (according to Figure 4 In the process of using cat litter inside the placement cavity 2021 of the bin body 2, when the controller 21 controls the driving assembly to make the bin body 2 that has cleaned the feces rotate clockwise, the bin body 2 will rotate until the emitting end of the photoelectric sensor 8 is aligned with the first opening, and then the controller 21 controls the driving assembly to make the bin body 2 rotate counterclockwise until the emitting end of the photoelectric sensor 8 is aligned with the second opening, at which time the bin body 2 is reset; by controlling the rotation of the bin body 2 to align the emitting end with the first opening, it is ensured that the cat litter entering the temporary storage cavity 2022 can completely flow back to the inside of the placement cavity 2021.

[0040] In this embodiment, as a further optimized solution, please refer to Figure 4 A garbage bag is put on the opening 14, and the garbage bag is located on the inner side of the garbage cavity 201, which is used to collect feces discharged from the opening 14, so that the feces discharged from the bin body 2 can also be collected by the garbage bag; a pressing plate 15 is hinged in the inner cavity of the garbage cavity 201, and the pressing plate 15 is used to press the entrance of the garbage bag; when the bin body 2 rotates counterclockwise to discharge feces, the pressing plate 15 rotates under the action of gravity and does not contact the partition 11, releasing the pressure on the garbage bag, allowing the feces to enter the garbage bag normally, and when the bin body 2 rotates clockwise to reset, the pressing plate 15 rotates under the action of gravity, and presses and seals the upper opening of the garbage bag again to prevent the odor from escaping.

[0041] Please note that Figure 4 A cover plate 10 is mounted on the left side wall of the bin body 2; when the feces is collected by using a garbage bag, the sewage outlet 9 is covered by the cover plate 10.

[0042] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 5 A baffle 13 is detachably provided in the inner cavity of the placement cavity 2021 (such as by a snap-on method), and the baffle 13 is used to separate the placement cavity 2021 from the temporary storage cavity 2022, so that when the bin body 2 rotates counterclockwise, the cat litter inside the placement cavity 2021 can be discharged through the opening 14, making it more convenient to replace the cat litter.
