[0031] In order to facilitate replacement of the filter module 3, as Figure 6As shown, the filter module 3 is connected with the back of the bin body 2 through a clamping structure, the clamping structure includes an embedded groove 23 arranged on the back of the bin body 2, and a clamping plate 24 is arranged on each of two sides of the embedded groove 23; the filter module 3 is an activated carbon filter, the filter module 3 is embedded into the embedded groove 23, and the clamping plates 24 on the two sides of the embedded groove 23 clamp the two side surfaces of the filter module 3, so that the filter module 3 is positioned in the embedded groove 23.

[0032] In use, the pet sand is placed in the bin body 2, when the pet pulls out the feces on the pet sand, the feces will be bonded with the pet sand into a fecal ball, in order that the pet toilet which can purify the air in the bin can filter the fecal ball, so as to facilitate cleaning, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9As shown, the bin body 2 is rotatably mounted on the base 1, and the rotation axis of the bin body 2 relative to the base 1 is arranged along the front-rear direction; a partition plate 25 is mounted in the bin body 2, which divides the inner cavity of the bin body 2 into a pet accommodating space and a pet litter filtering space; the lower side of the pet litter filtering space is provided with a litter filtering opening communicating with the pet accommodating space, and a sieve plate 26 is arranged on the litter filtering opening; a litter basin 20 is further mounted in the pet accommodating space during use, and the sieve plate 26 is located between the litter basin 20 and the partition plate 25, and the litter filtering opening is arranged close to the basin opening of the litter basin 20; one side edge of the sieve plate 26 is formed with a connecting portion 261 at the front and rear ends, respectively, and the partition plate 25 is formed with a limiting groove 251 at the front and rear ends of the side edge for forming the litter filtering opening; the connecting portion 261 of the sieve plate 26 at the front and rear ends is correspondingly rotatably mounted in the limiting groove 251 of the partition plate 25, so that the sieve plate 26 is rotatably mounted on the partition plate 25, and the rotation axis of the sieve plate 26 relative to the partition plate 25 is also arranged along the front-rear direction. In the state that the litter basin 20 is at the bottom of the bin body 2, the pet litter filtering space is located on the right side of the bin body 2, and the litter filtering opening is arranged downward, and in the process of rotating the bin body 2 counterclockwise from front to back and directly to the bin body 2 to gradually arrange the litter filtering opening upward for filtering litter, the sieve plate 26 will be arranged on the litter filtering opening under the action of its own gravity and the pet litter, so that the pet litter can enter the pet litter filtering space through the sieve holes of the sieve plate 26, and then the fecal pellets are filtered out; after the fecal pellets are removed, the bin body 2 is rotated clockwise from front to back and directly to the bin body to reset (i.e., the litter basin 20 is in the state of being at the bottom of the bin body 2), so that the litter filtering opening is gradually arranged downward, and at this time the sieve plate 26 is rotated under the action of its own gravity and the gravity of the pet litter to open a small opening of the litter filtering opening, so that the pet litter in the pet litter filtering space quickly enters the litter basin 20 in the pet accommodating space; and due to the design that the connecting portion 261 of the sieve plate 26 is arranged in the limiting groove 251, the limiting groove 251 will block the connecting portion 261 during rotation of the sieve plate 26, so that the opening of the sieve plate 26 will not be too large, avoiding that the sieve plate 26 occupies the pet accommodating space, and further avoiding that the sieve plate 26 scratches the pet.

[0033] In order to make the pet toilet capable of purifying the air in the bin more convenient to use, the fecal pellets do not need to be manually cleaned, and the fecal pellets can be automatically cleaned by the pet toilet.

A cover plate 27 is rotatably arranged on the bin body 2, and a reset spring (not shown in the drawings) is arranged between the cover plate 27 and the bin body 2. The reset spring is used to push the cover plate 27 to move outward from the bin body 2 to close the fecal pellet outlet. A switch mechanism 7 and a fecal pellet processing mechanism 8 are arranged on the base 1. A fecal pellet through hole 13 is arranged on the base 1, and the fecal pellet processing mechanism 8 is provided with a fecal pellet inlet which is opposite to the fecal pellet through hole 13. The switch mechanism 7 comprises a switch motor 71 and a switch arm 72. The switch motor 71 is arranged on the base 1. One end of the switch arm 72 is connected with the rotating shaft of the switch motor 71, and the other end of the switch arm 72 is provided with a roller 73 which is used to push the cover plate 27 to open. The switch mechanism 7 of the embodiment is arranged in the base 1, and an elongated hole is formed in the base 1 for the switch arm 72 and the roller 73 to move out. In use, the switch arm 72 is rotated to push away the cover plate 27 through the rotation of the switch motor 71.
