Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pet supplies, and in particular to a litter bin structure and a pet toilet. Background Art
[0002] A pet litter box is a device that holds litter for pets to excrete. To save energy and maintain litter hygiene, some pet litters are equipped with automatic cleaning features. Screening is a highly effective cleaning method. Litter boxes using screening cleaning technology are generally divided into a waste chamber, a litter chamber, and a main chamber. A screen is placed between the litter chamber and the main chamber.
[0003] The screening-type automatic cleaning process generally starts when the litter bin senses that the pet has left the litter bin, and the litter bin starts to rotate, causing the litter in the main chamber to contact the screen for screening; after screening, the unused litter enters the litter chamber, and the used litter and excrement remain in the main chamber; then, the sand bin rotates further until the used litter and excrement move to the entrance of the excrement chamber and enter the excrement chamber; finally, the sand bin rotates in the opposite direction until the unused litter in the litter chamber passes through the screen and flows back into the main chamber.
[0004] Because the interior of the litter bin needs to be divided into at least three chambers, and given the overall requirement for pet litters to be small and compact, the volume of each chamber in the litter bin is limited. This limits the capacity of the excrement chamber, requiring users to clean the excrement chamber at short intervals. Furthermore, unused litter enters the chamber during the screening process, requiring the chamber to accommodate as much unused litter as possible. Given the limited volume of each chamber, the amount of litter that can be loaded into the litter bin is also limited. Utility Model Content
[0005] In view of this, the purpose of the present application is to provide a litter bin structure and a pet toilet, which are used to solve the problem of the small volume of the excrement chamber and / or the litter chamber in the screening pet toilet.

[0018] The movable part can be deformed toward the direction of the stool sand cavity.
[0019] Furthermore, the movable member can switch between a flat state and a concave state by deformation;
[0020] In the flat state, the movable member is in the form of a sheet;
[0021] In the recessed state, the movable part is recessed into the feces and litter cavity or into the excrement cavity to form a bowl shape.
[0022] Furthermore, a plurality of mounting parts are provided in the sand bin;
[0023] A plurality of the mounting members are arranged in the stool and litter chamber and / or the excrement chamber;

For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0050] See also Figure 1 In a first aspect, an embodiment of the present application provides a litter bin structure, comprising a litter bin 10. The litter bin 10 can be mounted on a base 20 of a pet litter box, and the litter bin 10 can rotate on the base 20.
[0051] The sand bin 10 is provided with: a main chamber 11, a fecal sand chamber 12, an excrement chamber 13, a screen 14 and a movable part 15; the fecal sand chamber 12 is provided between the main chamber 11 and the excrement chamber 13; a screen 14 is provided on the side of the fecal sand chamber 12 close to the main chamber 11.
[0052] Specifically, when the sand bin 10 is in the reset state, the fecal litter is located at the bottom of the sand bin 10 and is now located in the main chamber 11. Above the fecal litter is the fecal litter chamber 12, and above the fecal litter chamber 12 is the excrement chamber 13. For example, if both the fecal litter chamber 12 and the excrement chamber 13 are arranged in the clockwise direction of the main chamber 11, when the sand bin 10 rotates counterclockwise, the fecal litter will slide downward until it contacts the screen 14. After being filtered by the screen 14, the unused fecal litter enters the fecal litter chamber 12, while the used fecal litter and pet excrement remain in the main chamber 11. As the sand bin 10 rotates further, the used fecal litter and pet excrement reach the entrance of the excrement chamber 13. The sand bin 10 can then rotate clockwise or remain stationary, allowing the used fecal litter and pet excrement to enter the excrement chamber 13.
[0053] A movable member 15 is provided on the side of the feces chamber 12 adjacent to the excrement chamber 13. Specifically, the movable member 15 is disposed between the feces chamber 12 and the excrement chamber 13, separating the two. The movable member 15 is movable toward the excrement chamber 13 and / or toward the feces chamber. The movable member 15 is a movable structure, and its movement can include overall movement, such as sliding, or local movement, such as deformation.
[0054] Taking the example of a movable member 15 that can only move toward the excrement chamber 13, when the sand bin 10 rotates to the point where the fecal litter can enter the interior of the sand chamber 12, the fecal litter is located above the sand chamber 12. At this time, the unused fecal litter that has entered the sand chamber 12 is located above the movable member 15. When the fecal litter is located above the movable member 15, the fecal litter pushes the movable member 15 toward the excrement chamber 13, thereby increasing the storage space of the sand chamber 12. When the sand bin 10 subsequently rotates to the point where used fecal litter and excrement enter the excrement chamber 13, the fecal litter and excrement push the movable member 15 toward the sand chamber 12, returning the storage space of the excrement chamber 13 and the fecal litter chamber 12 to their original size, thereby not affecting the original storage capacity of the excrement chamber 13. This method can increase the fecal litter storage capacity of the sand chamber 12, thereby increasing the fecal litter loading capacity of the sand bin 10 while maintaining the overall volume of the sand bin 10.
[0055] Taking the example of the movable part 15 being movable only toward the fecal sand chamber 12, when the sand bin 10 rotates to the point where the fecal sand can enter the fecal sand chamber 12, the fecal sand chamber 12 enters the sand feeding process. At this time, the fecal sand is located above the fecal sand chamber 12, and the unused fecal sand passes through the screen 14 and enters the fecal sand chamber 12. Since the movable part 15 cannot move toward the excrement chamber 13, the movable part 15 remains in position at this time. When the sand bin 10 subsequently rotates to the point where the used fecal sand and excrement enter the excrement chamber 13, the fecal sand chamber 12 enters the sand discharge process. The fecal sand and excrement push the movable part 15 toward the fecal sand chamber 12 to increase the accommodation space of the excrement chamber 13. At this time, the unused fecal sand in the fecal sand chamber 12 can flow back into the main chamber 11 through the screen 14. This method can increase the excrement loading capacity of the excrement chamber 13 without affecting the storage capacity of the excrement chamber 12 during the sand feeding process, that is, without affecting the original excrement loading capacity of the sand bin 10, so as to extend the user's cleaning interval, which is more beneficial for users who need to take a long time to clean due to business trips or travel.
[0056] Taking the example of the movable part 15 being movable toward both the excrement chamber 13 and the fecal sand chamber 12, when the sand bin 10 rotates to the point where the fecal sand can enter the fecal sand chamber 12, the fecal sand chamber 12 enters the sand feeding process. At this time, the fecal sand is located above the fecal sand chamber 12, and unused fecal sand passes through the screen 14 and enters the fecal sand chamber 12. The fecal sand that enters the fecal sand chamber 12 is located above the movable part 15, pushing the movable part 15 toward the excrement chamber 13, thereby increasing the storage space of the fecal sand chamber 12 and accommodating more fecal sand. When the sand bin 10 subsequently rotates to the point where used fecal sand and excrement enter the excrement chamber 13, the fecal sand and excrement push the movable part 15 toward the fecal sand chamber 12, thereby increasing the storage space of the excrement chamber 13. At this time, the unused fecal sand in the fecal sand chamber 12 can flow back into the main chamber 11 through the screen 14. That is, in this manner, the storage capacity of the feces sand chamber 12 can be increased during the sand feeding process of the feces sand chamber 12 , while the capacity of the excrement chamber 13 can be increased, thereby improving the space utilization rate inside the sand bin 10 .
[0057] It should be noted that, in use, a storage bag can be provided in the excrement chamber 13, into which the fecal litter and excrement entering the excrement chamber 13 are stored. A removable lid is provided on the outside of the excrement chamber 13; by opening the removable lid, the storage bag can be removed and replaced with a new one.
[0058] As an implementation, see Figure 2 and Figure 3 The movable member 15 can be moved toward the excrement chamber 13 and / or the feces chamber 12 by providing a guide member 131 in the excrement chamber 13. Figure 2 In the illustrated embodiment, the guide member 131 is provided in the excrement chamber 13 as an example. The guide member 131 may be a slide structure for the movable member 15 to slide, specifically, the movable member 15 can slide along the guide member 131. When the movable member 15 slides toward the excrement chamber 13, the volume of the feces chamber 12 can be increased.
[0059] In an embodiment where the movable member 15 can only move toward the excrement chamber 13, a limiter can be provided in the feces chamber 12; the limiter is used to restrict the entry of the movable member 15 so that the movable member 15 can only slide toward the excrement chamber 13. In other words, in this embodiment, the volume of the feces chamber 12 can be increased by the movement of the movable member 15, but cannot be reduced by the movement of the movable member 15.
[0060] Similarly, in the embodiment where the movable member 15 can only move toward the feces and litter chamber 12 , a limiting member can be provided in the excrement chamber 13 to restrict the movable member 15 from entering.
[0061] In the embodiment in which the movable part 15 can move toward the excrement chamber 13 and the fecal litter chamber 12, a guide structure can also be provided in the fecal litter chamber 12 to enable the movable part 15 to slide into the fecal litter chamber 12; thereby, the volume of the fecal litter chamber 12 can be increased or decreased by the movement of the movable part 15.
[0062] In an embodiment provided in the present application, the movable member 15 may also be a flexible member.
[0063] For example, the movable member 15 may be a high-density polyethylene film or a polypropylene film structure; since the movable member 15 is a flexible member, the movable member 15 can be folded or unfolded.
[0064] As an embodiment, the movable part 15 of the flexible structure can be unfolded into a bag shape, so that when the fecal litter is located above the movable part 15, it can be pushed by gravity to expand the movable part 15 toward the excrement cavity 13, and then part of the fecal litter is stored through the movable part 15, thereby increasing the volume of the fecal litter cavity 12 and increasing the storage capacity of the fecal litter cavity 12.
[0065] In a further improved embodiment, the movable member 15 is an elastic member. In this embodiment, the movable member 15 is a deformable structure; when deformed, the movable member 15 can accommodate a certain amount of fecal sand; when the sand bin 10 rotates until the movable member 15 is above the fecal sand, the movable member 15 can be reset by the elastic force.
[0066] In application, the movable member 15 is, for example, a silicone pad, a rubber pad, etc.
[0067] Compared with the movable member 15 which is only a flexible structure, in this embodiment, the movable member 15 is an elastic member, which can prevent the movable member 15 from being unable to return to its original position and occupying the internal space of the excrement cavity 13.
[0068] Compared with the movable part 15 of the sliding structure, in this embodiment, the movable part 15 is an elastic part, which can make the two ends of the movable part 15 fixedly connected to the sand bin 10. On the one hand, the connection structure is simpler, and on the other hand, it can prevent foreign matter from entering the gap due to the gap in the sliding structure.
[0069] Based on the above-mentioned movable part 15 being an elastic part, in another embodiment provided by the present application, the movable part 15 is arranged between the feces and sand chamber 12 and the excrement chamber 13; the movable part 15 can be deformed toward the excrement chamber 13; the movable part 15 can be deformed toward the feces and sand chamber 12.
[0070] Specifically, see Figures 4 and 5 , taking the sand chamber 12 and the excrement chamber 13 as an example, which are located in the clockwise direction of the main chamber 11 , in this embodiment, the automatic cleaning process of the sand bin 10 may include states 1 to 7.
[0071] State 1 is when the sand bin 10 is in the initial state;
[0072] State 2 is based on state 1, and the sand bin 10 rotates counterclockwise so that the feces and excrement come into contact with the screen 14.
[0073] State 3 is based on State 2, and the litter bin 10 further rotates counterclockwise, so that the unused litter completely enters the litter chamber 12, while the used litter and pet excrement gradually move to the inlet and outlet 16 of the excrement chamber 13;
[0074] State 4 is based on state 3. The litter bin 10 rotates further counterclockwise. At this time, the used litter and pet excrement have moved to the inlet and outlet 16 of the excrement chamber 13 and gradually enter the excrement chamber 13.
[0075] State 5 is based on state 4, and the sand bin rotates clockwise to shovel the used feces and pet excrement into the excrement chamber 13;
[0076] State 6 is based on state 5, and the sand bin 10 further rotates clockwise. At this time, the used fecal litter and pet excrement have completely entered the excrement cavity 13.
[0077] State 7 is based on state 6. The sand bin 10 rotates further clockwise. At this time, the sand bin 10 rotates to the same reset state as state 1, and the used fecal litter and pet excrement have been transferred to the excrement chamber 13, completing the automatic cleaning of the used fecal litter and pet excrement.
[0078] As shown in state 3 above, when unused litter enters the litter chamber 12, the movable member 15 is deformed toward the excrement chamber 13 due to the weight of the unused litter, thereby increasing the volume of the litter chamber 12. At this time, the used litter and pet excrement are not yet ready to enter the excrement chamber 13, and do not affect the use of the excrement chamber 13.
[0079] As shown in state 6 above, after the used litter and pet excrement enter the excrement chamber 13, the movable member 15 can be deformed toward the litter chamber 12 due to the gravity of the used litter and pet excrement, thereby increasing the volume of the excrement chamber 13. At this time, the used litter and pet excrement have all entered the excrement chamber 13, so the litter in the litter chamber 12 can flow back into the main chamber 11, without affecting the automatic cleaning process.
[0080] It can be seen that the movable part 15 provided in this embodiment can increase the volume of the fecal sand chamber 12 and the excrement chamber 13 respectively under different conditions, and when the volume of one of them increases, it does not affect the use of the other, so that when the total volume of the fecal sand chamber 12 and the excrement chamber 13 occupied by the sand bin 10 remains unchanged, the utilization rate of each space is effectively improved, and the space of the fecal sand chamber 12 and the space of the excrement chamber 13 are increased at the same time.
[0081] Optionally, the movable member 15 can be formed into a bowl shape after deformation, so as to better accommodate feces and pet excrement.
[0082] Specifically, the movable part 15 can switch between a flat state and a recessed state through deformation; in the flat state, the movable part 15 is sheet-shaped; in the recessed state, the movable part 15 is recessed into the feces chamber 12 or into the excrement chamber 13 to form a bowl shape.
[0083] The movable member 15 can be configured to deform into a bowl-shaped structure by adjusting the elastic modulus at different locations on the movable member 15. For example, the movable member 15 includes, from the inside out, a central region, an annular region, and an outer region. The outer region has a higher elastic modulus and is used to securely connect to the sand bin 10. The annular region has a lower elastic modulus and is capable of greater deformation. The central region has a higher elastic modulus than the annular region, so that when the movable member 15 is subjected to force, the annular region deforms more significantly, thereby supporting the movable member 15 in a bowl-shaped configuration.
[0084] Based on any of the above embodiments, please refer to Figure 6 A plurality of mounting members 18 are provided in the sand bin 10; the plurality of mounting members 18 are provided in the fecal sand chamber 12 and / or the excrement chamber 13; the plurality of mounting members 18 are distributed at intervals along the arrangement direction of the fecal sand chamber 12 and the excrement chamber 13; the movable member 15 can be detachably provided on any mounting member 18.
[0085] Taking the example of the movable part 15 being movable toward the excrement chamber 13 and the feces and litter chamber 12, multiple mounting parts 18 are arranged at intervals in the feces and litter chamber 12 and the excrement chamber 13, so that the movable part 15 can be selectively installed on any mounting part 18. Therefore, the user can adjust the volume of the feces and litter chamber 12 and the excrement chamber 13 as needed.
[0086] In application, the mounting member 18 may be a groove structure, a supporting structure, etc., and specifically, the mounting member 18 can be used to mount the movable member 15 .
[0087] Taking the mounting frame 18 as an example of a groove structure, the outer periphery of the movable part 15 can be snapped into the mounting frame 18; wherein, the inner periphery of the movable part 15 can be a deformable structure, so that the movable part 15 can be deformed and the outer periphery can be inserted into the groove structure.
[0088] For example, if the mounting frame 18 is a supporting structure, the movable member 15 is placed on the mounting frame 18 and then secured by a connecting structure such as bolts. Accordingly, the mounting frame 18 may be provided with a clearance groove so that when the mounting frame 18 located below is installing bolts, the mounting frame 18 located above will not interfere with the installation of the bolts.
[0089] In one embodiment, an inlet and outlet 16 is provided inside the excrement cavity 13 ; a movable door 17 is provided on the inlet and outlet 16 .
[0090] Specifically, the excrement chamber 13 is configured so that when feces and pet excrement approach the inlet and outlet 16, the movable door 17 is located in the lower area of the litter bin 10, so that the movable door 17 can be automatically opened by gravity.
[0091] In one embodiment, the movable door 17 may be a sliding door. When the movable door 17 is rotated to the lower area in the sand bin 10, for example, in the aforementioned state 3, the movable door 17 can be caused by gravity to slide away from the feces sand chamber 12, thereby opening the inlet and outlet 16. When the movable door 17 is rotated to the upper area in the sand bin 10, for example, in the aforementioned state 6, the movable door 17 can be caused by gravity to slide toward the feces sand chamber 12, thereby closing the inlet and outlet 16.
[0092] As another embodiment, the movable door 17 may be a flip door. When the movable door 17 is rotated to the lower area within the sand bin 10, such as in the aforementioned state 3, the movable door 17 can flip under the force of gravity to open the inlet and outlet 16. When the movable door 17 is rotated to the upper area within the sand bin 10, such as in the aforementioned state 6, the movable door 17 can flip under the force of gravity to close the inlet and outlet 16.
[0093] Optionally, in this embodiment, the movable door 17 is an outward-turning door, that is, when the movable door 17 is opened, it needs to be opened in a direction away from the excrement chamber 13. Correspondingly, a counterweight block can be provided on the movable door 17 to ensure that the movable door 17 can open and close the inlet and outlet 16 under the force of gravity, thereby avoiding the situation where the movable door 17 is not sensitive to opening and closing.
[0094] In the case where the movable door 17 is an inner flip door, when it is opened, the movable door 17 flips toward the inside of the excrement chamber 13, compressing the internal space of the excrement chamber 13; when the movable door 17 is closed, the movable door 17 may push the feces or excrement above it to the outside of the excrement chamber 13, affecting the cleaning effect.
[0095] Compared with the inward flipping method, in this method, when the movable door 17 is opened, the inlet and outlet 16 has a larger normally open area; when the movable door 17 is closed, if there is fecal sand or excrement on the movable door 17, as shown in state 5, the movable door 17 can also push the fecal sand and excrement into the excrement cavity 13, thereby ensuring the cleaning effect.
[0096] A second aspect of the present application provides a pet litter box, comprising: a base 20 and any one of the above-mentioned litter bin structures; the litter bin 10 in the litter bin structure can be rotatably disposed on the base 20 .
[0097] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
