Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pet products, in particular to a rolling shovel type automatic cat litter box. BACKGROUND

[0002] Cats are a popular family pet worldwide, and their personalities have their own unique characteristics. Cats are animals that like to be clean and have high vigilance. After defecating, they will bury their excrement. Cat litter boxes are used as pet cat toilet supplies, making it easy to clean up pet feces. Therefore, for people who raise pet cats, cat litter boxes are essential components. In order to facilitate the cleaning of cat excrement, the breeder will usually prepare a cat litter box and then train the cat to defecate in it. After that, the breeder will clean the cat litter box regularly.

[0003] Cat litter boxes mainly include ordinary cat litter boxes and intelligent cat litter boxes. Ordinary cat litter boxes are gradually being phased out because they are very inconvenient to use and need to be cleaned after each use. Most breeders prefer intelligent cat litter boxes that can automatically clean feces. Existing intelligent cat litter boxes are mainly divided into the following two types:

[0004] 1. A drum type cat litter box has a closed cavity inside, which has a sand hiding area and a screen area. Although it can play a role in cleaning feces, due to its structural characteristics, the feces collection bin is placed at the bottom of the drum, which greatly compresses the space of the feces collection bin.

[0005] 2. A flat shovel type cat litter box is mainly composed of a sand bin body and a screen, which cleans feces by moving the screen. The obvious disadvantage of this scheme is that the feces in the sand bin cannot be wrapped with cat litter through rolling, so it is easy to smear feces on the sand bin side wall during cleaning, causing serious pollution, and even possibly causing the product to malfunction. In addition, due to the structure of the flat shovel type, the feces collection bin is relatively short, which compresses the storage space of the feces collection bin, resulting in the user needing to frequently empty the feces, which brings a very poor experience to the user.

[0031] The basin 1 also includes a litter collection bin 5 for collecting waste cat litter, located directly below the mixing bin 2. After the cat litter in the mixing bin 2 has been used for a period of time, the main control board controls the first drive mechanism to rotate the mixing bin 2 until one end of the mixing bin 2 connects to the litter collection bin 5. The cat litter in the mixing bin 2 will then roll out of the mixing bin 2 due to its own gravity and fall into the litter collection bin 5 for collection. The litter collection bin 5 is connected to the drawer of the basin 1, with one end extending out of the basin 1. A second handle 51 is provided at the end extending out of the basin 1. By holding the second handle 51, the litter collection bin 5 can be pulled out of the basin 1, making it easy to empty the waste cat litter in a timely manner.

[0032] The basin body 1 includes a bottom shell 102 and a top cover 103. The top cover 103 is fitted onto the upper end of the bottom shell 102 and is detachably connected to the bottom shell 102.

By arranging the arc-shaped groove 104, the feces and cat litter in the mixing bin 2 can be prevented from falling into the interior of the basin 1, thereby ensuring the cleanliness of the interior of the basin 1; by arranging the collection hole 105, when the waste cat litter is poured, after the mixing bin 2 rotates, the cat litter in the mixing bin 2 will roll into the arc-shaped groove 104 and then fall into the sand collecting bin 5 under the action of its own gravity, thereby ensuring that all the cat litter can fall into the sand collecting bin 5.

[0037] As shown in Figure 5 , 6 shown, the second driving mechanism includes a second driving motor 11, the second driving motor 11 is electrically connected with the control mainboard, the second driving motor 11 is fixedly installed in the interior of the basin 1, and the output end of the second driving motor 11 is fixedly connected with the sieve shovel 4. In specific work, when the feces and litter mixture needs to be scooped out, the second driving motor 11 is controlled to work to drive the sieve shovel 4 to rotate, so that the sieve shovel 4 extends into the mixing bin 2 to push the feces and litter mixture to roll in the mixing bin 2, the cat litter will leak out of the hollow groove 41 of the sieve shovel 4, and the feces and litter mixture will be pushed to the edge of the mixing bin 2 along with the continuous rotation of the sieve shovel 4, until the feces and litter mixture is pushed to above the feces collecting bin 3, and then the feces and litter mixture will roll and fall into the feces collecting bin 3 under the action of its own gravity, thereby realizing the function of automatic cleaning.

[0038] As shown in Figure 1 , in order to facilitate the pet cat to smoothly enter the mixing bin 2 for convenience, on the one hand, the feces collecting bin 3 is arranged below the cat entrance and exit 101, and one end of the feces collecting bin 3 extends out of the basin 1, and an anti-skid climbing path 32 is arranged on the upper end face of the end of the feces collecting bin 3 extending out of the basin 1. In the embodiment, the anti-skid climbing path 32 includes a plurality of anti-skid grooves arranged in an array on the basin 1; in other embodiments, the anti-skid climbing path 32 can also be other anti-skid structures, such as anti-skid protrusions, protrusions, etc. By arranging the anti-skid climbing path 32, the pet cat can climb and jump to the cat entrance and exit 101 through the feces collecting bin 3. On the other hand, a cover plate 12 is arranged in the basin 1 at a position corresponding to the cat entrance and exit 101, one end of the cover plate 12 is hingedly connected with the basin 1, the other end is a free end, and the free end can be connected with the mixing bin 2; by arranging the cover plate 12, the pet cat can smoothly enter the mixing bin 2 after entering the cat entrance and exit 101. Specifically, when the pet cat needs to enter the cat litter basin for convenience, it can jump to the anti-skid climbing path 32 and then climb and jump to the cat entrance and exit 101, and then enter the mixing bin 2 through the cover plate 12 for convenience.

[0039] As shown in Figure 3As shown, the cover plate 12 is arranged directly above the excrement collecting bin 3, and the free end of the cover plate 12 is provided with a pushing block 13 which is an arc-shaped strip structure bending upward as a whole; during the rotation of the sifting shovel 4 driven by the second driving motor 11, the sifting shovel 4 can be in contact with the pushing block 13 and push the cover plate 12 to rotate around the hinged end as the axis, so as to push the cover plate 12 to open and expose the excrement collecting bin 3 below the cover plate 12, so that the excrement-sand mixture scooped out by the sifting shovel 4 can roll into the excrement collecting bin 3 for collection.

[0040] Working principle:

[0041] The user pours cat litter into the mixing bin 2 in advance, and when the pet cat needs to relieve itself, it will jump to the anti-skid ladder 32 and then climb and jump to the cat entrance and exit 101 to enter the mixing bin 2 through the cover plate 12 to relieve itself.

[0042] After the pet cat relieves itself, the first driving motor 8 is controlled to rotate forward and reverse repeatedly by operating the control switch 7, so as to drive the mixing bin 2 to rotate back and forth, and the excrement and cat litter are rolled and mixed together to form an excrement-sand mixture. After the first driving motor 8 works for a predetermined time, the second driving motor 11 is controlled to work to drive the sifting shovel 4 to rotate, so that the sifting shovel 4 extends into the mixing bin 2 to push the excrement-sand mixture to roll in the mixing bin 2, and the cat litter will leak out of the hollow slot 41 of the sifting shovel 4; as the sifting shovel 4 continues to rotate, the sifting shovel 4 will be in contact with the pushing block 13 and push the cover plate 12 to rotate around the hinged end, thereby exposing the excrement collecting bin 3. After the sifting shovel 4 pushes the excrement-sand mixture out of the edge of the mixing bin 2, the excrement-sand mixture will roll and fall into the excrement collecting bin 3 under the action of its own gravity, realizing automatic cleaning of the excrement-sand mixture.

[0043] When the cat litter in the mixing bin 2 is used for a period of time, the first driving motor 8 is controlled to work by operating the control switch 7 to drive the mixing bin 2 to rotate counterclockwise until one end of the mixing bin 2 is aligned with the sand collecting bin 5, and the cat litter falls into the sand collecting bin 5 under the action of its own gravity, realizing automatic collection of waste cat litter.
