The sealing component 121 includes a support plate 1211 connected to the housing 11, screws 1213 respectively connected to both sides of the support plate 1211, and screws 1213 connected to the screw 121. 3 side of the motor 1212, the first clamping plate 1214 and the second clamping plate 1215 respectively connected to the screw 1213 at both ends, the synchronous belt 1216 connected to the screw 1213 on both sides of the support plate 1211, and the exhaust fan 123 located on the side below the support plate 1211, the first clamping plate 1214 and / or the second clamping plate 1215 are provided with a heating wire, the exhaust fan 123 is opposite to the position of the air outlet, the screw 1213 is provided with a first thread 12131 and a second thread 12132, the first thread 12131 and the second thread 12132 are provided. The rotation directions of the thread 12132 are opposite, the lengths of the first thread 12131 and the second thread 12132 are equal, a first opening is provided on the support plate 1211, the screw 1213 is respectively located on both sides of the first opening, the first clamping plate 1214 and the second clamping plate 1215 are respectively located at both ends of the first opening, the placement plate 122 is provided with a second opening, a placement groove located on the peripheral side of the second opening, and an upper cover 1221 located above the placement groove, an opening is provided between the inner side of the upper cover 1221 and the placement groove, and the funnel 124 is located above the second opening.

[0048] After the pet defecates, the collecting device 13 moves the feces in the litter box 14 into the funnel 124. The pet feces passes through the funnel 124 through the second opening and the first opening and falls into the plastic bag. When a certain amount of pet feces is collected in the plastic bag, the motor 1212 is started, and the motor 1212 drives the screw 1213 to rotate. Due to the action of the synchronous belt 1216, when the motor 1212 drives the screw 1213 on one side of the support plate 1211 to rotate, the screws 1213 on both sides of the support plate 1211 are rotated. 213 rotates synchronously. Since the first thread 12131 and the second thread 12132 on the lead screw 1213 rotate in opposite directions, when the lead screw 1213 rotates, the first clamping plate 1214 and the second clamping plate 1215 are relatively close to each other. When the first clamping plate 1214 and the second clamping plate 1215 are in contact with each other, the plastic bag is located in the first clamping plate 1214 and the second clamping plate 1215.
