[0002] Nowadays, many families raise pet cats, and in order to keep the living environment clean and hygienic, cat litter boxes are used to collect the excrement of pet cats. In order to reduce the workload of cleaning the excrement, people now use intelligent automatic cat litter boxes.

[0003] At present, most automatic cat litter boxes are provided with two packing rods that can move relative to each other, and a garbage bag is sleeved on the packing rods. When the excrement in the garbage bag is full, the two packing rods move relative to each other to close the garbage bag, and then the two packing rods are lifted synchronously, so that a new garbage bag is taken off and replaced. Alternatively, a plurality of suction buckles are arranged around the garbage bag. When it is necessary to replace the garbage bag, the plurality of suction buckles are accumulated together to close the garbage bag, so that a new garbage bag is taken out and replaced.

[0076] The first rotary motor 3211 can drive the first driving wheel to rotate, so as to drive the first transmission member to rotate around the first driving wheel and the first driven wheel, and then drive the first driven wheel to rotate, that is, the first driving wheel drives the first driven wheel to rotate through the first transmission member. The first packing rod 322 is connected to the first transmission member, so that the rotation of the first transmission member can drive the first packing rod 322 to move along the X direction.

[0077] The second transmission mechanism 3213 comprises a second driving wheel, a second driven wheel and a second transmission member. The second driving wheel is in transmission connection with the output end of the first rotary motor 3211. The second driving wheel and the second driven wheel are arranged in the Y direction. The second transmission member is arranged around the second driving wheel and the second driven wheel.

[0078] The first rotating motor 3211 can drive the second driving wheel to rotate, so as to drive the second transmission member to rotate around the second driving wheel and the second driven wheel, and then drive the second driven wheel to rotate, i.e., the second driving wheel drives the second driven wheel to rotate through the second transmission member. The second packing rod 323 is connected to the second transmission member, so that the second transmission member can drive the second packing rod 323 to move along the Y direction.

[0079] When it is needed to fold the garbage bag, the first rotating motor 3211 is started to drive the first driving wheel and the second driving wheel to rotate at the same time, so as to drive the first transmission member to rotate along the X direction and the second transmission member to rotate along the Y direction, respectively, and drive the first packing rod 322 to move along the X direction and the second packing rod 323 to move along the Y direction, so as to fold the garbage bag, tighten the garbage bag to the sealing assembly 33, and ensure the sealing of the garbage bag, prevent the garbage bag from having a leakage at the sealing, avoid the overflow of excrement odor and cat litter dust, and avoid the spilling when the garbage bag is discarded, and ensure the use experience of the breeder.

[0080] In the embodiment, the first transmission member includes a transmission belt.

The side of the first gathering plate 3222 facing the second packing rod 323 is provided with a first inclined surface gradually away from the second packing rod 323 in the direction away from the first rod body 3221. When the first transmission member drives the first packing rod 322 to move in the X direction, the first gathering plate 3222 can limit the bag body of the garbage bag on the side of the first inclined surface close to the second packing rod 323.

[0084] In some embodiments, the second packing rod 323 can include a second rod body and a second gathering plate arranged on the side of the second rod body close to the sealing assembly 33. The second gathering plate faces the sealing assembly 33 and is provided with a second inclined surface on the side facing the first packing rod 322, which gradually away from the first rod body 3221 in the direction away from the second rod body. When the second transmission member drives the second packing rod 323 to move in the Y direction, the second gathering plate can limit the bag body of the garbage bag on the side of the second inclined surface close to the second packing rod 323. Through the cooperation of the first gathering plate 3222 and the second gathering plate, the bag body of the garbage bag can be completely gathered and accumulated, preventing the bag body from being missed to cause the sealing to be not tight.

[0085] In other embodiments, the second packing rod 323 can also not be provided with a second gathering plate.

[0086] The sealing assembly 33 is provided with a third inclined surface on the end close to the second rod body, which is arranged on the side of the sealing assembly 33 facing the first rod body 3221 and gradually away from the first rod body 3221 in the direction from the first transmission member to the second packing rod 323. As the first packing rod 322 and the second packing rod 323 move to continuously approach the sealing assembly 33, the bag body of the garbage bag is continuously gathered, and the bag opening is gradually reduced. When the garbage bag is gathered to the range of the sealing assembly 33, the third inclined surface can guide the garbage bag into the space surrounded by the sealing assembly 33, the first packing rod 322 and the second packing rod 323, so that the bag opening of the garbage bag is completely tightened to the sealing assembly 33, avoiding the bag body to be missed to cause the sealing to be not tight, ensuring the sealing of the garbage bag sealing, preventing the excrement odor and cat litter dust from overflowing.

[0087] In the embodiment, the sealing assembly 33 comprises a sealing plate and a heating element. The sealing plate is provided with a third inclined surface. The first packing rod 322 and the second packing rod 323 cooperate to tighten the garbage bag to abut against the sealing plate. The heating element is arranged around the periphery of the sealing plate. After the garbage bag is tightened to abut against the sealing plate, the heating element is powered to heat, so that the heating element heat-seals the garbage bag. The sealed garbage bag falls into the excrement collecting box 2. The bottom of the new garbage bag is sealed by the garbage bag sealing, so as to facilitate the collection of excrement of the pet again.
