[0002] As people's living standards continue to improve, they are beginning to pursue a richer spiritual life, and many choose to add color to their lives by keeping pets. Cats, due to their inherent qualities, have become the top choice for pets. Owning a cat can bring its owner great satisfaction, but it also presents many challenges. Cleaning up after a cat, in particular, is a major inconvenience for many cat owners.
[0003] There are generally two types of existing cat litter boxes. One type uses a sieve plate to automatically filter out cat feces and collect the waste in a sealed box, which is then manually removed and disposed of periodically. This method of storing cat feces in a sealed box has drawbacks. Because several days' worth of feces are piled up together, it is very unhygienic and will emit an odor. Therefore, this method has problems with poor hygiene and incomplete odor sealing. Utility Model Content
[0004] The purpose of this invention is to provide an environmentally friendly litter changing system for home pets. This system uses rotation to filter clumped cat litter, storing clean litter in a collection bag while discharging clumped litter through rotation. Furthermore, it can absorb and extract odors from the rotating drum, effectively reducing odor dispersion. This addresses the technical problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An eco-friendly pet litter changing system, including

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0046] Please see Figure 1-12 In this embodiment of the present invention, an environmentally friendly litter changing system for home pets includes a rotating drum 1 capable of rotating and automatically cleaning clumped cat litter. The drum 1 has a body 101, with a rubber conical part 102 sleeved on the outside of the open end of the body 101. A cat litter plate 104 is provided on the bottom side inside the body 101, and an opening slot 107 is provided through the top of the cat litter plate 104. A wireless camera 108 is fixed inside the body 101. The wireless camera 108 can monitor the cat litter situation inside the body 101. After the cat relieves itself, the system can automatically rotate after monitoring the cat leaving the body 101 to process the clumped cat litter.
[0047] A filter screen 105 is provided on one side of the litter box 104. There is a gap between the filter screen 105 and the cylinder 101 to facilitate the flow of cat litter to the litter collection bag 106. The litter collection bag 106 is located on the side of the filter screen 105 away from the litter box 104.
[0048] More specifically, a gear 9 is also installed on the straight tube 4; there are two gears 9, and the other gear 9 is installed on the output shaft of the motor 10, and the two gears 9 are meshed and connected; the motor 10 is fixedly connected to the horizontal plate placed inside the outer casing 16 through the motor base 11.
[0049] By adopting the above technical solution, when processing clumped cat litter, the motor 10, with the cooperation of two gears 9, drives the straight pipe 4 welded to the inside of the rotating drum 1 to rotate. The cat litter in the drum 101 flows from the litter plate 104 to the filter screen 105. The clumped cat litter remains on top, while the loose cat litter falls below the filter screen 105. As the drum 101 continues to rotate, the loose cat litter enters the litter collection bag 106 for temporary storage, while the clumped cat litter continues to roll. When the opening slot 107 rotates to directly below the drum 101, the clumped cat litter falls through the opening slot 107 into the collection box 14. This achieves the collection of clumped cat litter and waste, making it convenient for pet owners to handle.
[0050] A straight pipe 4 is welded to one end of the cylinder 101 away from the opening. The straight pipe 4 is connected to a gas collection hood 6 via a rotary joint 5. An activated carbon filter 7 is fixed inside the rotary joint 5 and the gas collection hood 6, and the activated carbon filter 7 is in close contact with the exhaust fan 17.
[0051] After the cat defecates, the exhaust fan 17 turns on to draw out the odorous air inside the cylinder 101 through the straight pipe 4. When it passes through the air collection hood 6, it will also pass through the activated carbon filter 7 for odor adsorption, thereby reducing the spread of odor and achieving odor removal.
[0052] In this embodiment, a bearing is installed on the straight pipe 4, and the bearing is fixed on the U-shaped hanger 8. The upper end of the hanger 8 is provided with a fixing rod extending to the rear of the rotating cylinder 1, and the fixing rod is fixed to the outer shell 16.
[0053] The above technical solution can not only realize the hoisting of the rotating drum 1, but also ensure the normal rotation of the rotating drum 1, and does not affect the stroke of the electric push rod 12 when it rotates, thus avoiding the situation of motion interference.
[0054] In this embodiment, a rake plate 13 is attached to the cat litter board 104 to facilitate spreading the cat litter. The rake plate 13 is fixed to the push rod end of the electric push rod 12. The electric push rod 12 is fixed to the rear side of the cylinder 101.
[0055] More specifically, the top of the outer shell 16 is also integrally provided with a sand storage cavity 15, which is located directly above the opening groove 107.
[0056] By adopting the above technical solution, when too much clumped cat litter is discharged, the amount of loose cat litter inside will decrease and cannot be evenly spread on the cat litter plate 104; at this time, the control system can control the small slide valve at the bottom of the litter storage chamber 15 to open, so that the dry and loose cat litter inside the litter storage chamber 15 flows onto the cat litter plate 104, thereby increasing the amount of cat litter.
[0057] The flowing cat litter will gather together. At this time, the electric push rod 12 will reciprocate under the drive of the control system to spread the gathered cat litter evenly, so as to avoid the cat litter gathering and causing inconvenience to the cat.
[0058] In this embodiment, a slot is provided at the lower front end of the outer shell 16 to facilitate the pulling out of the collection box 14, and an exhaust slot is provided at the rear of the outer shell 16 to facilitate the exhaust of the exhaust fan 17.
[0059] As a further explanation of the above embodiments, the control system is a simple DC drive control; the control system includes a microcontroller, whose I / O input and output terminals are respectively connected to a wireless receiving module and a wireless transmission module, which can analyze the image information transmitted from the wireless camera, and can interact with the customer's mobile terminal through the wireless transmission module to realize remote control;
[0060] Under the instructions issued by the microcontroller, the drive module can control the movement of the motor or electric actuator to complete the cleaning of clumped cat litter and the spreading of cat litter.
[0061] This control system is existing technology, and its principle will only be briefly described here; the specific circuit relationships will not be elaborated further.
[0062] The working principle of this utility model is as follows: When processing clumped cat litter, the motor 10, with the cooperation of two gears 9, drives the straight pipe 4 welded to the inner side of the rotating drum 1 to rotate. The cat litter in the drum 101 flows from the litter plate 104 to the filter screen plate 105. The clumped cat litter remains on top, while the loose cat litter falls below the filter screen plate 105. As the drum 101 continues to rotate, the loose cat litter enters the litter collection bag 106 for temporary storage, while the clumped cat litter continues to roll. When the opening slot 107 rotates to directly below the drum 101, the clumped cat litter falls through the opening slot 107 into the collection box 14. This achieves the collection of clumped cat litter and waste, making it convenient for pet owners to handle.
[0063] After the clumps of cat litter are cleaned up, the cylinder 101 rotates in the opposite direction, and the cat litter stored in the litter collection bag 106 will flow back onto the litter board 104. With the continuous swaying of the cylinder 101, the cat litter will be flattened.
[0064] After the cat defecates, the exhaust fan 17 turns on to draw out the odorous air inside the cylinder 101 through the straight pipe 4. When it passes through the air collection hood 6, it will also pass through the activated carbon filter 7 for odor adsorption, thereby reducing the spread of odor and achieving odor removal.
[0065] When too much clumped cat litter is discharged, the amount of loose cat litter inside decreases, making it impossible to spread evenly on the litter box 104. At this time, the control system can control the small slide valve at the bottom of the litter storage chamber 15 to open, allowing the dry and loose cat litter inside the litter storage chamber 15 to flow onto the litter box 104, thus increasing the amount of cat litter. The flowing cat litter then gathers together, and the electric push rod 12, driven by the control system, reciprocates to spread the gathered cat litter evenly, preventing the cat litter from gathering and causing inconvenience for the cat.
[0066] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
