As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0020] As shown in Figure 1 , the present application discloses a pet litter box 10 based on injection molding, comprising a feces collection box 20 and a litter circulation box 30 placed on the feces collection box 20. As shown in Figure 2 , the litter circulation box 30 comprises a litter storage bin 100, a movable base plate 200, and a one-way valve 300.
[0021] It should be noted that in the present application, the feces collection box 20, the litter storage bin 100, the movable base plate 200, and the one-way valve 300 are respectively injection molded; the feces collection box 20, the litter storage bin 100, the movable base plate 200, and the one-way valve 300 are all made of plastic material.
[0022] As shown in Figure 2 , the litter storage bin 100 is a hollow cavity structure with an upper opening 101, as shown in Figure 3 , the litter storage bin 100 forms a litter sealed cavity 110 and a litter open cavity 120 inside, and an arc-shaped ramp 130 is formed between the litter sealed cavity 110 and the litter open cavity 120.
[0023] The movable base plate 200 is arranged at the upper opening 101 of the litter storage bin 100 (as shown in Figure 1 and Figure 2 ), so that the litter sealed cavity 110 is in a sealed state and the litter open cavity 120 is in an open state.
[0024] A throat narrow opening 400 is formed between the movable base plate 200 and the arc-shaped ramp 130 (as shown in Figure 3 and Figure 4 ), and the one-way valve 300 is movably hinged on the movable base plate 200 and located at the throat narrow opening 400, so that the litter sealed cavity 110 and the litter open cavity 120 are in a through state or a blocked state.
[0025] As shown in Figure 3 and Figure 4 , the movable base plate 200 has a cat litter laying area 210 and a cat litter backflow area 220. In this embodiment, a plurality of blind holes are formed on the cat litter laying area 210, which are arranged in a rectangular array; a plurality of through holes are formed on the cat litter backflow area 220, which are arranged in a rectangular array and are located above the cat litter sealing cavity 110.
[0026] In this application, the injection-molded pet cat litter basin 10 further comprises a cat litter leveling paddle 40 (as shown in Figure 3 and Figure 4 ), which is housed in or taken out of the cat litter open cavity 120.
[0027] Further, two opposite inner walls of the feces collection box 20 are respectively provided with support protrusions 21 (as shown in Figure 2 , and an avoidance space 140 (as shown in Figure 4 ) is formed at the arc-shaped ramp 130 of the cat litter sealing cavity 110 and the cat litter open cavity 120; when the cat litter circulation box 30 is placed horizontally on the feces collection box 20, the support protrusions 21 are located in the avoidance space 140; when the cat litter circulation box 30 is placed obliquely on the feces collection box 20, the arc-shaped ramp 130 abuts against the support protrusions 21 or the edge of the feces collection box 20.
[0028] Next, the use method of the injection-molded pet cat litter basin 10 with the above structure will be described: As shown in Figure 5 , pour the cat litter 50 into the cat litter sealing cavity 110 of the cat litter storage bin 100; As shown in Figure 5 , install the movable base plate 200 at the upper opening 101 of the cat litter storage bin 100, so that the cat litter sealing cavity 110 is in a sealed state and the cat litter open cavity 120 is in an open state; As shown in Figure 5 , movably hinge the one-way valve 300 to the movable base plate 200; when the cat litter circulation box 30 is placed horizontally on the feces collection box 20, the one-way valve 300 will cover the throat narrow opening 400 under the action of gravity, so that the cat litter sealing cavity 110 and the cat litter open cavity 120 are in a blocked state; As shown in Figure 5 , lay a layer of flat cat litter 50 on the cat litter laying area 210 of the movable base plate 200 for the pet cat to excrete feces; When the pet cat excretes feces on the litter laying area 210, part of the litter 50 on the litter laying area 210 will absorb water on the feces and form clumps, and based on the behavior habit of the pet cat, the pet cat will also use the paw to stir the litter to further cover the excreted feces; As shown in Figure 6 , the pet owner starts to clean the feces on the litter laying area 210, lifts one end of the litter circulation box 30, so that the litter circulation box 30 is in an inclined state, and then under the action of gravity, the unused litter (litter not wrapped with feces) and the clumped litter (litter wrapped with feces) on the litter laying area 210 are simultaneously poured out to one side; As shown in Figure 6 , because the clumped litter has a large volume, when passing through the litter backflow area 220, it will not fall into the litter sealing cavity 110 through the small through holes, but directly drop into the feces collection box 20 through the litter backflow area 220; As shown in Figure 6 , the unused litter does not form clumps and still maintains the original fine particle shape, and when passing through the litter backflow area 220, most of the litter will fall into the litter sealing cavity 110 through the small through holes in the litter backflow area 220, and will not drop into the feces collection box 20, so the litter not wrapped with feces can be reused; the pet owner can apply a shaking force to the litter circulation box 30 to make the unused litter fall more smoothly into the litter sealing cavity 110; of course, at this time, the litter leveling paddle 40 can also be used, first, the clumped litter is removed from the litter leveling paddle 40, and then the litter leveling paddle 40 is blocked at the edge of the movable base plate 200 to prevent the unused litter from falling into the feces collection box 20; At this time, it is particularly pointed out that because the litter storage bin 100 stores litter, the entire litter circulation box 30 is very heavy, and if the entire litter circulation box 30 is lifted and suspended in the air, it will be very laborious; to solve this technical problem, in the present application, as shown in Figure 6 , support protrusions 21 are arranged on the two opposite inner walls of the feces collection box 20, and the pet owner only needs to drag the litter circulation box 30 to one side, and the arc-shaped ramp 130 will slide along the support protrusions 21, so that the litter circulation box 30 is easily in an inclined state, and the bottom of the litter circulation box 30 is supported by the support protrusions 21 and is not suspended in the air, which is very convenient and labor-saving to operate; As shown in Figure 7As shown, when clumped cat litter falls into the feces collection box 20 and unused cat litter flows back into the cat litter sealed chamber 110, the pet owner applies force to the cat litter circulation box 30, causing it to tilt towards the cat litter open chamber 120. At this time, the cat litter in the cat litter sealed chamber 110 will flow along the curved ramp 130 towards the cat litter open chamber 120. Under the action of gravity, the cat litter breaks through the blockage of the one-way valve 300, and the narrow throat 400 is in an open state. It should be noted that at this time, the curved ramp 130 is against the edge of the feces collection box 20 (e.g., Figure 7 As shown in the figure, the edge of the feces collection box 20 forms a support point for the entire cat litter circulation box 30, so pet owners do not need to lift the entire cat litter circulation box 30, making the operation very convenient and effortless. like Figure 8 As shown, after a certain amount of cat litter is collected in the open cat litter chamber 120, the pet owner applies force to the cat litter storage chamber 100 to make it lie flat (it can be tilted appropriately towards the cat litter sealed chamber 110 so that the backflow at the narrow throat opening 400 can flow into the cat litter sealed chamber 110). Under the action of gravity, the one-way valve 300 re-seals the narrow throat opening 400. The one-way valve 300 re-seals the narrow throat opening 400, which creates conditions for the cat litter to flow from the open cat litter chamber 120 to the cat litter laying area 210. like Figure 9 As shown, the pet owner applies force to the litter storage compartment 100, causing it to tilt towards the litter sealed chamber 110. This allows the litter in the open litter chamber 120 to reach the litter distribution area 210 via the one-way valve 300. For better results, a litter leveling tool 40 (such as...) can be used. Figure 9 As shown), the cat litter in the open cat litter chamber 120 is scraped out and spread evenly on the cat litter laying area 210; in this embodiment, several blind holes are formed on the cat litter laying area 210. The blind holes can store a portion of the cat litter and create a certain resistance to the flow of the cat litter, preventing the cat litter from being lost quickly. like Figure 10 As shown, after cat litter is re-laid on the litter area 210, the pet owner applies force to the litter storage bin 100 to make it lie flat again. The litter storage bin 100 resets and seals the feces collection box 20 to prevent odors from escaping from the feces collection box 20.
[0029] like Figure 2 As shown, in this invention, the cat litter storage compartment 100 is provided with a handle 150, and the side wall of the feces collection box 20 is provided with a clearance groove 22 that cooperates with the handle 150. By providing the handle 150, pet owners can easily apply force to the entire cat litter circulation box 30 by holding the handle 150.
[0030] like Figure 2As shown, in the present application, the cat litter storage bin 100 is provided with a left baffle 102 and a right baffle 103 at the upper opening 101, and the left baffle 102 and the right baffle 103 are respectively located on both sides of the movable base plate 200. By arranging the left baffle 102 and the right baffle 103, the left baffle 102 and the right baffle 103 are higher than the movable base plate 200, which can effectively prevent the cat litter laid on the movable base plate 200 from falling off. Further, as shown Figure 2 As shown, the left baffle 102 is provided with a left guide groove 104, and the right baffle 103 is provided with a right guide groove, and the movable base plate 200 is respectively inserted into the left guide groove 104 and the right guide groove, and the left guide groove 104 and the right guide groove are arranged to limit the movable base plate 200, and the movable base plate 200 is installed at the upper opening 101 of the cat litter storage bin 100 in a pulling manner.
[0031] The pet cat litter basin 10 based on injection molding has the following beneficial effects: 1. The cat litter storage bin 100 forms a cat litter sealed cavity 110 and a cat litter open cavity 120 inside, an arc-shaped ramp 130 is formed between the cat litter sealed cavity 110 and the cat litter open cavity 120, and a throat narrow mouth 400 is formed between the movable base plate 200 and the arc-shaped ramp 130. This structure design facilitates the reciprocating circulation of cat litter, and only needs to tilt the cat litter circulation box 30 back and forth, and the cat litter can form circulation among the cat litter open cavity 120, the cat litter sealed cavity 110 and the movable base plate 200, which is very convenient to operate; 2. The one-way valve 300 is movably connected to the movable base plate 200 and located at the throat narrow mouth 400, so that the cat litter sealed cavity 110 and the cat litter open cavity 120 are in a through state or a blocking state. This structure design, together with the back-and-forth tilting operation of the cat litter circulation box 30, the one-way valve 300 blocks or penetrates the throat narrow mouth 400 under the action of gravity, not only solves the problem of cat litter in the cat litter sealed cavity 110 entering the cat litter open cavity 120, but also solves the problem of cat litter in the cat litter open cavity 120 flowing to the movable base plate 200 by using the one-way valve 300; 3. When the cat litter circulation box 30 is tilted and placed on the feces collection box 20, the arc-shaped ramp 130 abuts against the supporting protrusion 21 or the edge of the feces collection box 20. In this way, when replacing the cat litter, it is not necessary to lift the entire cat litter circulation box 30, but to form a supporting force by means of the supporting protrusion 21 or the edge of the feces collection box 20. It is worth noting that the arc-shaped ramp 130 is a smooth arc-shaped structure, which is beneficial to the smooth sliding of the bottom of the entire cat litter circulation box 30 on the supporting protrusion 21; 4. When the litter box 30 is placed flat on the feces collection box 20, the support protrusion 21 is located in the clearance space 140. It can be seen that the support protrusion 21 makes full use of the clearance space 140 to achieve the purpose of support. Without this clearance space 140, the litter box 30 would interfere with the feces collection box 20, and the litter box 30 would be difficult to place flat on the feces collection box 20. In addition, the support protrusion 21 is a small protrusion formed on the side wall of the feces collection box 20. The support protrusion 21 does not need to penetrate through the two side walls of the feces collection box 20 to achieve the support function.
[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
