Pet toilet

Abstract

According to the pet toilet, due to the fact that the supporting plate for supporting the pad body is arranged, the supporting plate can cover the protruding framework, the pad body is supported by the supporting plate, the pad body is made to be higher than the bottom face of the first containing space, and then pet sand can be placed on the pad body so that the containing space of the first containing space can be reduced; when a large amount of cat litter is needed, the pad body and the supporting plate can be detached, so that the cat litter is directly contained on the bottom face of the first containing space, and the containing space of the first containing space is increased. Moreover, if the supporting plate is not arranged, the flexible pad body is easy to fall into the gaps among the supporting frameworks, so that the effect of adjusting the use amount of the cat litter cannot be achieved, and the supporting plate for supporting the pad body is arranged, so that the pad body can be effectively prevented from falling into the gaps among the supporting frameworks, and the effect of adjusting the use amount of the cat litter by the pad body is more obvious.

The first bottom wall 701 is connected with the first outer side wall 70, and the distance between one side of the first bottom wall 701 and the bottom end of the first outer side wall 70 is a first distance. The distance between the other side of the first bottom wall 701 and the bottom end of the first outer side wall 70 is a second distance. The first distance is different from the second distance, so that the first bottom wall 701 is arranged at an inclined angle. Through the above structure, when the excrement is discharged into the second accommodating space 71 of the excrement collecting box 7 through the second opening 72, the excrement can slide to one side of the first bottom wall 701 along the inclined surface on the other side of the first bottom wall 701, so as to prevent the excrement from being accumulated on the other side of the first bottom wall 701 below the second opening 72. In the embodiment, the middle part of the screen assembly 3 is recessed towards the inner wall of the roller 1 to form a flow guide channel 32. Through the above structure, the excrement can be discharged into the excrement collecting box through the first opening 11 and the second opening 72 along the flow guide channel 32.

[0053] The screen assembly 3 comprises a first part 33 connected with the drum 1 and a second part 34 connected with the first part 33 and located between the first part 33 and the first containing space 111, and the second part 34 has a plurality of screen holes 341. Specifically, the depth of the flow guide channel 32 increases in the direction from the second part 34 to the first part 33, and the width of the flow guide channel 32 decreases in the direction from the second part 34 to the first part 33. Further, the first part 33 comprises a first baffle 331 and a second baffle 332, one side of the first baffle 331 is connected with the second part 34, the middle part of the other side of the first baffle 331 is connected with the middle part of the drum 1, and the two ends of the other side of the first baffle 331 are connected with the two ends of the drum 1 through the second baffle 332, and the second baffle 332 is arranged at an acute angle, a right angle or an obtuse angle with the first baffle 331. At the same time, the second baffle 332 can also block the pet sand, preventing the pet sand from splashing to the external environment when the drum 1 rotates. In the embodiment, the first connecting piece, the second connecting piece, the third connecting piece, the fourth connecting piece and the fifth connecting piece are all screws or bolts. The first elastic piece, the second elastic piece and the third elastic piece are all torsional springs.

[0054] With reference to Figure 25 The pet toilet comprises a drum 1 having a first opening 11 and a first containing space 111, the first opening 11 is communicated with the first containing space 111, and the first containing space 111 is used to contain the excrement of pets and pet sand; a plurality of protruding skeletons 1111 are arranged in the first containing space 111, and gaps 101 exist between the plurality of protruding skeletons 1111.

[0055] The pet toilet further comprises a support plate 10, which is detachably covered on the bottom surface of the skeletons 1111, the gaps 101 and the first containing space 111.

[0056] The pet toilet further comprises a flexible pad 1112, which is detachably covered on the surface of the support plate, the support plate is arranged between the pad and the skeletons, and the support plate is used to support the pad. Through the above structure, since the support plate for supporting the pad is arranged, the support plate can cover the protruding skeletons, and the support plate supports the pad so that the pad is higher than the bottom surface of the first containing space, and then the pet sand can be placed on the pad to reduce the containing space of the first containing space, so as to facilitate the user to adjust the amount of cat sand. When the demand for the amount of cat sand is large, the pad and the support plate can be detached, so that the cat sand is directly placed on the bottom surface of the first containing space to increase the containing space of the first containing space. Moreover, if there is no support plate, the flexible pad is easy to fall into the gaps between the support skeletons, so that the effect of adjusting the amount of cat sand cannot be achieved. Since the support plate for supporting the pad is arranged, the pad can be effectively prevented from falling into the gaps between the plurality of support skeletons, so that the effect of adjusting the amount of cat sand is more obvious.

[0057] In the embodiment, the hardness of the support plate is greater than the hardness of the cushion body. The support plate is a flat surface support plate. Specifically, the support plate is a plastic support plate or a metal support plate or a bamboo support plate or a wooden support plate. Further, the support plate is a PVC support plate. Through the above structure, the setting of the support plate is effectively realized, and because the hardness of the support plate is greater than the hardness of the cushion body, the support plate can effectively support the cushion body and prevent the cushion body from collapsing. Further, because the support plate is a flat surface support plate, the cat litter can be more evenly laid in the cushion body supported by the support plate. Further, the plastic support plate or the metal support plate or the bamboo support plate or the wooden support plate has a long service life, is convenient to produce, and is convenient for users to clean.
