Wherein, the drum 30 is rotatably provided to the housing 10. The intelligent cat toilet further comprises a driving mechanism in transmission connection with the roller and used for driving the roller 30 to rotate. The driving mechanism is electrically connected with the controller and comprises a driving motor (not shown) and a transmission structure, and the specific transmission structure is a gear transmission structure. Referring to fig. 3, the gear transmission structure includes a large gear 52 coaxially disposed with the drum 30 and a small gear (not shown) engaged with the large gear 52, the small gear is engaged with the large gear 52 to perform deceleration, and the driving motor drives the small gear and the large gear 52 to rotate, thereby performing rotation of the drum 30 around its axis.
The drum 30 has a pet entrance 32 for the pet cat to enter and exit, and a discharge compartment 34 is defined therein, through which pet cat enters the discharge compartment 34. In a normal use condition (as shown in fig. 1), the drainage compartment 34 is located at the very bottom of the drum 30, i.e. closer to the ground, and for clarity of description, the drum is referred to as an initial position in this position. In the initial position, litter within the drum 30 collects at the bottom of the waste compartment 34 and, after a pet cat enters the waste compartment 34 through the pet inlet 32, the litter is disposed beneath the pet cat to receive waste from the pet cat.
In this embodiment, the drum 30 further comprises a screening device. Specifically, referring to fig. 2, the screening device includes a spiral screen 36 and a screen 35. The outlet of spiral sifter 36 is connected with the waste outlet 360 of drum 30, the inlet of spiral sifter 36 is connected with screen 35, screen 35 has a plurality of screen holes, the size of screen hole allows the cat litter to pass through, but the excrement caking of large granule will obstruct on the surface of screen 35, and in the rotation process of drum 30, the excrement caking rolls onto spiral sifter 36 and is guided to waste outlet 360 along with the rotation of spiral sifter 36.
The smart cat litter box 100 further includes a litter box 40, the litter box 40 is located below the side of the waste discharge opening 360, and the excrement falling from the waste discharge opening 360 is agglomerated and falls into the litter box 40 to be temporarily stored.

In the prior art, a pet cat enters the drum and automatically leaves the drum from the pet inlet after excretion is finished. When the pet cat is detected to leave, the intelligent cat toilet automatically starts an excrement screening program, and the driving roller rotates to screen the excrement. If the detection is not accurate, part of the body of the pet cat still exists in the roller when the roller rotates, and the pet cat is pinched and injured.
Referring now to fig. 2 and 3 with emphasis on the pet identification sensor, it is used to detect whether a pet cat is inside the drum 30. Specifically, the pet identification sensor is arranged in the roller 30 and comprises an emitting end 22 for emitting the detection signal and a receiving end 24 for receiving the detection signal, the emitting end 22 and the receiving end 24 are both arranged on the inner wall of the roller 30 and are respectively positioned at two sides of the excretion room 34, when a pet cat is positioned in the excretion room 34, a straight path between the emitting end 22 and the receiving end 24 is blocked, the receiving end 24 cannot receive the detection signal, and the pet identification sensor sends out an identification signal for identifying the pet cat. When the pet cat comes out of the roller 30, the straight path between the emitting end 22 and the receiving end 24 is not blocked, the signal emitted by the emitting end 22 is directly transmitted to the receiving end 24 and received by the receiving end 24, and the signal emitted by the pet identification sensor is different from the identification signal, so that the pet cat can be judged not to be positioned in the roller 30 according to the different signal.
The controller is electrically connected to the pet recognition sensor for receiving the recognition signal and outputting a control signal for controlling the operation of the drum 30. In this embodiment, the controller is disposed in the housing 10 and connected to the pet identification sensor through a signal line. When the controller receives the identification signal, the operation of the drum is not automatically started, and the drum 30 is not started to rotate until the pet cat is detected not to be positioned in the drum 30, so that excrement can be screened.

In the embodiment, the casing 10 includes a lower casing 12 and an upper casing 14, the drum 30 is rotatably supported on the lower casing 12, and the upper casing 14 is covered above the drum 30. There is a gap between the upper casing 14 and the drum 30. In order to reduce the risk of trapping the cat, an elastic support structure is provided between the lower housing 12 and the upper housing 14, and the elastic support structure abuts against the upper housing 14 and is used for applying a pre-tightening force to the upper housing to return to the first position. That is, the gap is variable under the influence of the resilient support structure, and the upper housing 14 has a first position and a second position relative to the lower housing 12, wherein the gap between the lower housing 12 and the upper housing 14 is different in size, and the gap in the first position is greater than the gap in the second position. If a pet cat plays in the roller 30, when the pet inlet 32 rotates to the upper part and is shielded by the upper shell 14, part of the body of the pet cat extends out of the pet inlet 32 and touches the upper shell 14, at the moment, the upper shell 14 moves to the first position, and the gap between the upper shell 14 and the lower shell 12 is increased, so that a larger space is left for the pet cat to prevent clamping injury.
In the exemplary embodiment, upper housing 14 has a generally flat upper surface to provide a platform for a pet cat to rest and play with.
In the present application, a position switch electrically connected to the controller is provided on the lower housing 12.

When the position switch is activated, it is recognized that there is pressure on the upper housing 14, and it may be that a pet cat is jumping onto the upper housing 14, and the weight data from the load cell may be combined to determine that a pet cat is positioned on the upper housing 14. Therefore, in the embodiment, the pet cat can be more accurately identified to be positioned on the shell.
The position switch can be a micro switch or a Hall switch. When the position switch is a hall switch, the trigger part includes a magnet.
When the controller determines that the pet cat is positioned on the upper shell 14, the excrement screening program can be started according to the program at the moment, the weighing data of the weighing sensors do not contain the weight of the pet cat, therefore, the excrement screening can be normally carried out, and the risk that the excrement stays in an excrement room for too long time and emits peculiar smell is reduced.
In the embodiment, the drum 30 includes a circumferential side wall and two end walls respectively disposed at two ends of the side wall, and the transmitting end and the receiving end are respectively disposed on the two end walls of the drum. Specifically, both end walls of the drum 30 are substantially perpendicular to the rotational axis of the drum 30 around which the side wall of the drum 30 is wound, and the section of the side wall perpendicular to the rotational axis of the drum 30 is substantially circular. The rotational axis of the drum 30 passes through the centers of both end walls.
More specifically, the emitting end 22 and the receiving end 24 are arranged substantially along a direction parallel to the rotational axis of the drum 30. That is, the emitting end 22 and the receiving end 24 are oppositely disposed with their center lines parallel to the rotational axis of the drum 30.
In one embodiment, the pet identification sensor is a laser sensor, and accordingly, the transmitting end 22 is a laser transmitter, the receiving end 24 is a laser receiver, and the detection signal is a laser signal.
When a pet cat is in a excretion room, the pet cat sometimes makes a motion of arching the body, and a situation that the transmitting end 22 and the receiving end 24 of the pet identification sensor are not blocked may occur, and at this time, misjudgment may occur. In order to reduce the risk of misjudgment, in an embodiment, the transmitting end and the receiving end are arranged in a plurality of pairs, the positions of each pair of transmitting end and receiving end are different, the signal transmission paths are different, and the pet cat can be identified to be positioned in the roller as long as the pet cat blocks one of the transmission paths, so that the accuracy of identifying the pet cat is obviously improved.
It is obvious that the above described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, a person skilled in the art can make changes or changes in other different forms without creative work, and all should belong to the protection scope of the present invention.
