Description

Technical Field

[0001] The utility model relates to the technical field of pet supplies, in particular to an automatic pet toilet, and aims to provide an automatic, efficient and clean pet excrement treatment device. Background Art

[0002] As the number of pets in households grows, they bring joy and companionship, but also a host of worries for their owners. Pets face challenges related to eating, drinking, defecating, sleeping, playing, and more. Among these, defecation is particularly crucial, unconstrained by time, space, or the owner's will. When unable to hold it in, they'll surprise their owners with a treat anytime, anywhere. Cats, due to their unique characteristics, have litter boxes, including automatic ones. Dogs, on the other hand, have tray-type dog toilets and pet mats, but none of these address the fundamental problem. These products either require owners to promptly rinse the tray and the screen above it, and if the feces is hard, it can be difficult to flush down the drain or cause a blockage. Alternatively, they use pet mats, which must be cleaned and replaced immediately after use. Some dogs even tear up the mats, creating further problems. Few dogs are even capable of using human toilets. Therefore, a fully automatic, operator-free dog toilet is crucial. Utility Model Content

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] When the utility model is implemented, the action device:

[0025] Roller conveyor belt 101: As a component for carrying and conveying pet excrement, rollers are provided at both ends of the belt, and a gear is provided at one end of the roller for connecting with a driving device and a driven device.

[0026] Conveyor belt tensioning device 102: installed between the rollers, used to adjust the tension of the roller conveyor belt 101 to ensure stable operation.

[0027] DC drive motor 103: drives the roller conveyor belt 101 to operate. A drive gear 104 is installed on its shaft and meshes with the gear on the roller through a gear set.

[0028] Driven gear 105: installed on the same side end of the screw propeller 106 and the driving gear 104, meshing with the gear on the drum to achieve synchronous operation of the screw propeller.

[0029] The screw propeller 106 is located at the end of the roller conveyor belt 101 away from the DC drive motor 103 and is used to push the excrement to a designated location.

[0030] The cutting blade 107 and the mesh blade 108 are installed at the other end of the screw propeller 106 to break up the excrement for subsequent processing.

[0031] Drainage and sewage pipe 109: connected to the cutting blade 107 and the mesh blade 108, used to discharge the processed excrement.

[0032] The clean water spray pipe 110 is provided on the top of the screw propeller 106 and is used to clean the conveyor belt and the screw propeller.

[0033] Conveyor belt squeezing roller 111: is in contact with and connected to the bottom of the roller conveyor belt 101, and is used to squeeze out excess water.

[0034] Conveyor belt tray 112: provided below the roller conveyor belt 101, used for supporting and fixing the conveyor belt.

[0035] The wiper strip 113 is arranged between the conveyor belt squeezing roller 111 and the screw propeller 106, contacts the lower part of the conveyor belt, scrapes off residual stains and excess water, and prevents stains from entering the bottom of the housing and the side of the drive motor.

[0036] shell:

[0037] Bottom water trough 301: Located at the bottom of the roller conveyor 101, on the side of the DC drive motor 103, the housing curves downward to form a semicircular cavity for mounting components such as the DC drive motor 103, steam generator 502, UV germicidal lamp 503, infrared sensor 504, integrated control board 505, and camera 506. Away from the DC drive motor 103, the housing curves downward to form a semicircular cavity for mounting the propeller 106, spray water pipe 110, and conveyor belt squeeze roller 111. Together with the wiper strip 113, this forms a relatively enclosed sewage trough, conveniently collecting sewage generated during the cleaning process and facilitating the propeller 106 to remove dirt from the machine.

[0038] Side covers 302: are provided on both sides of the bottom water tank 301 to shield and protect the internal devices, and are provided with hinges for easy opening and cleaning.

[0039] End cover 1 303 and end cover 2 304 are respectively arranged at both ends of the bottom water trough 301 and are provided with hinges, wherein end cover 1 303 is arranged at the end where the screw propeller 106 is located, which is convenient for opening, repairing and cleaning the internal components; end cover 2 304 is arranged at the end where the DC drive motor 103 is located, which is used to further protect the internal components and is convenient for opening, repairing and cleaning the internal components.

[0040] When the side cover 302, the end cover 1 303 and the end cover 2 304 are opened at the same time, the roller conveyor belt can be taken out to clean the bottom pool of water 301 or to clean and replace the roller conveyor belt.

[0041] Control system:

[0042] Gravity sensors 501: There are two of them, symmetrically distributed along the center line of the conveyor tray 112, and used to detect the weight on the conveyor tray 112, thereby triggering a cleaning or protection program.

[0043] Steam generator 502: It is arranged at the bottom of the roller conveyor belt 101 near the DC drive motor 103 and is used to generate steam to perform high-temperature disinfection on the conveyor belt and excrement.

[0044] Ultraviolet germicidal lamp 503: is arranged on the top of the DC drive motor 103, and is used to further kill bacteria and viruses.

[0045] Infrared sensors 504: There are two of them, symmetrically distributed along the lower center line of the second end cover 304, used to detect whether pets have entered the toilet area to avoid injuries during the cleaning process.

[0046] Integrated control board 505: It is set in the cavity of end cover 2 304 near the DC drive motor 103 side, and is used to centrally control the operation and data transmission and management of the entire system. After opening the end cover 304, necessary operations can also be performed manually on the machine.

[0047] Camera 506: It is set between the two infrared sensors 504 and is used to monitor the internal situation of the toilet, making it convenient for users to view and manage it remotely.

[0048] Inspired by the working principles of home treadmills and meat grinders, after a dog defecates, infrared sensors, gravity sensors, and cameras send signals to the control system, which then calculates safety and initiates the cleanup process. The machine uses a water-absorbent roller conveyor belt to transport the feces to a collection trough on one side, integral to the outer shell. A screw propeller, similar to the principle of a meat grinder, pushes the feces toward the front, where cross-cutting blades and mesh blades further break up the feces. The screw's movement squeezes the feces into the sewer pipe. Simultaneously, the control system flushes the collection trough and roller conveyor belt with clean water. The conveyor belt's squeezing rollers squeeze any remaining water from the conveyor belt into the collection trough. This allows the broken feces to be easily discharged. At the other end, the roller conveyor belt is sterilized with high-temperature steam and ultraviolet light, ensuring a clean, hygienic, and odor-free machine. The side and end covers are easily accessible, allowing the conveyor belt, auger, and blades to be easily removed for belt replacement and cleaning, as well as cleaning, repair, and replacement of the blades and machine. Infrared sensors, cameras, and gravity sensors serve as safety components to ensure the safety of pets and the machine, and can also be used to record information. The integrated control panel is integrated with a Wi-Fi module to facilitate remote automatic or manual control of the machine.
