Description

Technical Field

[0001] This utility model relates to a detachable self-spraying cat litter box, and belongs to the field of pet supplies and equipment technology. Background Technology

[0002] To maintain a hygienic environment, pet cats usually use litter boxes for their excretion.

[0003] Because pet excrement has a strong odor, it can affect environmental hygiene if not treated promptly. Therefore, existing technologies employ deodorization solutions to treat pet excrement. For example, patent CN218337421U discloses a deodorizing cat litter box, including a seat, a roller, and a deodorizing mechanism. The seat has a litter compartment; the roller holds cat litter, with an inlet / outlet at one end and a waste outlet on its circumference, which communicates with the litter compartment; the roller is mounted on the seat, and the deodorizing mechanism is installed in the seat or the litter compartment. The odor-reducing mechanism is used to hold and spray deodorizing agent into the cat feces compartment. An atomizing plate is installed on the spray nozzle of the odor-reducing mechanism. This invention's litter box has an odor-reducing mechanism installed in the seat or the cat feces compartment. The odor-reducing mechanism sprays deodorizing agent into the cat feces compartment, thereby actively reducing the odor of cat feces in the compartment. The odor is not easily detected, resulting in a better user experience. However, the roller-type structure of this solution is prone to trapping cats, affecting their entry and exit. Furthermore, its odor-reducing mechanism is mainly controlled manually, making it impossible to intelligently maintain the real-time hygiene of the litter box. Therefore, a detachable self-spraying litter box is proposed to solve the problems existing in the prior art. Utility Model Content

[0018] See Figures 1-7As shown, the technical solution adopted in this specific embodiment is as follows: It includes a rotating sand basin 1, a base 2, a detachable spray seat 3, and a waste collection chamber 4. The detachable spray seat 3 is detachably mounted on the base 2. The rotating sand basin 1 is rotatably connected to the inner wall of the detachable spray seat 3. The waste collection chamber 4 is detachably mounted on the bottom of the base 2. A base plate 6 is provided at the bottom of the base 2. Several weight sensors 14 are provided on the base plate 6. A pressure plate 15 is provided above the weight sensors 14. A pressure column 16 is provided on the base 2 corresponding to the position of the pressure plate 15 and abuts against the pressure plate 15. A control panel 13 is provided on the front side of the base 2. A control main board 12 is provided inside the control panel 13 and is electrically connected to the weight sensors 14. In this embodiment, an automated deodorization method is adopted, that is, by setting several weight sensors on the base plate. The device monitors the entry of pets. The specific control signal triggering includes two stages. The first stage is the pet entry stage. When a pet enters the rotating litter box, the pressure column presses against the pressure plate, causing the weight sensor to detect a continuous increase in weight that remains constant for a certain period of time. This is the monitoring stage, where the weight sensor continues to monitor. After the pet finishes defecating and leaves the rotating litter box, the weight decreases and remains constant for a certain period of time. When the weight sensor detects that the weight has not changed for 10 seconds, a control signal is triggered, and the main board controls the atomizing mechanism to spray deodorization. This is the second stage, with a spray duration of 5 seconds. Through sensor-based deodorization control, the device can intelligently monitor the pet's excretion behavior when unattended, thereby better and more timely deodorization to ensure fresh air. In addition, after using cat litter for a period of time, the excrement needs to be cleaned to avoid using contaminated cat litter continuously. The control panel has an on / off switch and function buttons. When the litter changing function button is pressed, the litter box can be rotated. During the rotation, the excrement is separated from the clean cat litter, and the excrement falls into the collection bin. This makes the litter changing operation convenient and provides a better excretion environment for the pet. Both the rotating litter box and the detachable spray nozzle have quick-release structures, making it easier for users to clean the litter box.

[0019] More specifically, the detachable spray base 3 is threadedly connected to a spray head 9. The spray head 9 has a spray hole 91 facing the rotating sand basin 1. Several inclined spray grooves 911 are provided on the spray hole 91, converging at the inner end and dispersing at the outer end. The spray head 9 has a hollow structure, and the detachable spray base 3 has a U-shaped structure. A connecting cavity 31 is provided at the bottom of the side corresponding to the spray head 9, communicating with the spray head 9. Bearings 32 are provided on the inner walls of both sides of the detachable spray base 3. In this embodiment... In the example, the detachable spray holder is the final spraying mechanism for the deodorizing spray. Its overall structure is U-shaped and it is inserted into the base, allowing for quick installation and disassembly. At the same time, a connecting cavity is set as the installation connection structure and also as the channel for the atomized liquid. The atomized disinfectant liquid can enter the spray head from the connecting cavity and be scattered and sprayed out from several inclined spray slots, thereby forming a large-area atomization surface. The spray holes correspond to the position of the rotating sand basin cavity, so that the atomized disinfectant liquid can cover the entire cavity, thereby achieving deodorization and keeping the air fresh. To achieve the automatic sand changing function, a bearing is set up to cooperate with the rotating sand basin, thereby realizing the rotating sand basin on the detachable spray seat for sand changing.

[0020] More specifically, the base 2 includes a base frame 21, a front cover plate 22, and a rear cover plate 23. The front cover plate 22 and the rear cover plate 23 are snapped into the sides of the base frame 21. The main body of the base consists of three parts, facilitating assembly and subsequent cleaning. The front and rear cover plates are snapped into the base frame, allowing for quick assembly and disassembly. The base frame 21 consists of a central hemispherical cavity with an opening and several side support columns. The cavity opening extends downwards to the waste collection chamber 4. The hemispherical cavity of the base frame matches the shape of the rotating sand basin, thus preventing interference when the rotating sand basin rotates and changes sand. The excrement in the rotating sand basin can be... The waste falls into the collection chamber through the cavity opening for collection and processing. The front cover plate 22 has an installation groove that matches the control panel 13. The upper part of the base frame 21 is symmetrically provided with connecting seats 25. The base 2 is inserted into the detachable spray seat 3 through the connecting seats 25. The connecting seat 25 corresponding to the connecting cavity 31 is provided with a mist guide groove 251 that passes through the connecting seat 25. In this embodiment, the shape of the connecting seat matches the connecting cavity. After the two are inserted, they can fit tightly to ensure the connection is firm and ensure that the atomized disinfectant can smoothly enter the spray head without leakage. In one embodiment, a sealing ring is provided on the connecting seat to seal the connection with the connecting cavity.

[0021] More specifically, an atomizer 61 is electrically connected to the control main board 12 at the edge of the base plate 6. The base plate has a through hole at the atomizer location as a mounting hole. The atomizer 61 is connected to the mist guide groove 251 via a conduit. The bottom of the base plate 6 has four support feet 5, one of which, corresponding to the atomizer 61, serves as a disinfectant storage chamber. The base plate 6 and the atomizer 61 are sealed together, forming an atomizing mechanism. A negative ion generator is also integrated within the atomizer 61. In this embodiment, the atomizing mechanism is located on the base plate, with a conduit on the atomizer connecting to the mist guide groove. One of the four support feet serves as the disinfectant storage chamber, and both the support foot and the atomizer are sealed and mounted in a mounting hole on the base plate. The atomizer extracts and atomizes the disinfectant, then sprays the atomized liquid through a conduit (not shown) into the spray head, and finally sprays it evenly from the atomizing hole to cover the entire sand basin. When disinfectant needs to be added, simply open the back cover, remove the atomizer, and add new disinfectant. The atomizer integrates a negative ion generator and an ozone generator (not shown), which share a connecting conduit with the atomized disinfectant. While disinfecting, it generates negative ions and ozone to simultaneously disinfect, sterilize, and purify the air in the sand basin. A through hole is opened in the middle of the base plate 6 to cooperate with the cavity extension of the base frame 21. The drive power supply 62 is located at the rear end of the base plate 6 opposite to the atomizer 61 and is electrically connected to the control main board 12. The drive power supply is an AC power supply, which can be connected to the socket when in use.

[0022] More specifically, the control motherboard 12 integrates a main control chip 121 and a wireless communication module 122. The main control chip 121 uses an STM32F407VGT6 chip, and the wireless communication module 122 uses an ESP32-WROOM-32D chip. In this embodiment, the STM32F407VGT6 chip integrates a data interface for a weight sensor, enabling the processing of weight monitoring data and the sending of control commands. The wireless communication module enables terminal devices to control the litter box. Terminal devices, such as mobile phones or tablets, can download a corresponding APP and, after pairing, remote spraying and litter changing control can be achieved. At the same time, all spraying data and litter changing times are recorded in the APP, allowing users to understand the deodorization status and add disinfectant and litter in a timely manner. The intelligent automatic deodorization operation, combined with remote monitoring, achieves intelligent management and effectively ensures the hygiene of the litter box.

[0023] More specifically, four weight sensors 14 are symmetrically arranged and employ an HX711 24-bit high-precision ADC module. In this embodiment, to ensure the accuracy of intelligent sensing, four weight sensors are set up and an HX711 24-bit high-precision ADC module is used, which can accurately and quickly monitor and provide signal feedback on the pet's entry and exit.

[0024] More specifically, the rotating litter box 1 has an open hemispherical structure. In this embodiment, the rotating litter box adopts an open hemispherical structure, which makes it more convenient for pets to enter and exit. A filter assembly mounting groove 108 is symmetrically arranged on one side of its inner wall. A filter 102 is inserted into the lower part of the filter assembly mounting groove 108, and a baffle 101 is inserted into the upper part of the filter assembly mounting groove 108. The baffle 101, the filter 102, and the rotating litter box 1 together form a filter chamber. The baffle and the filter adopt an insert-type structure, which is more convenient. For easy disassembly and cleaning, the rotating litter box rotates during litter changing. The litter mixed with pet waste gradually tumbles onto the filter screen, while the remaining clean litter also tumbles onto the screen and falls into the filter chamber for storage. As the litter box continues to rotate, waste falls into the collection bin for disposal. When rotating in the reverse direction, clean litter falls back from the filter screen. Users can track litter changing frequency via an app, allowing for timely addition of new litter. The lower part of the rotating litter box 1 is connected by a screw... A mounting ring 103 is fixed in place, and a fixing groove 107 is provided on the inner side of the upper part of the mounting ring 103. An arc-shaped litter box 106 is engaged in the fixing groove 107. Since the litter box is the main carrier of cat litter, it needs to be cleaned after a period of use to ensure hygiene. Therefore, a detachable mounting ring is provided as a fixing component for the litter box. When cleaning is required, simply loosen the screw on the mounting ring to remove the mounting ring from the rotating litter box, and then remove the litter box from it for cleaning. Disassembly and installation are extremely convenient. The rotating litter box 1 has a rotating shaft 105 on both sides, which is connected to the bearing 32. The rotating shaft and the bearing cooperate to realize the smooth rotation of the rotating litter box. The rotating litter box 1 has a drive tooth groove 104 arranged circumferentially on the outer side of the middle part of the rotating litter box 1, perpendicular to the rotation axis of the rotating shaft 105. The drive tooth groove is arranged in the middle of the outer side of the middle part of the rotating litter box, which is the middle of the direction in which the pet enters and exits. The drive tooth groove is arranged from the opening position on one side of the rotating litter box to the opening position on the other side, and a stop is set at each opening position to prevent excessive rotation, so as to realize the rotation and litter changing operation.

[0025] More specifically, a drive motor 7 is provided on one side of the middle of the base plate 6, and a drive gear 8 is connected to the output end of the drive motor 7. A gear groove 24 is provided on one side of the middle of the base 2 corresponding to the position of the drive gear 8. The drive gear 8 passes through the gear groove 24 and meshes with the drive gear groove 104. The drive motor 7 is electrically connected to the control main board 12. In this embodiment, the drive motor drives the drive gear to rotate, so that the drive gear and the drive gear groove cooperate to drive the rotating sand basin.

[0026] More specifically, the lower part of the cavity of the base frame 21 is provided with symmetrical UV sterilization lamps 10 and infrared disinfection lamps 11. Both the UV sterilization lamps 10 and infrared disinfection lamps 11 are tilted downwards towards the feces collection chamber 4. In this embodiment, in order to ensure the overall hygiene of the litter box, the opposing UV sterilization lamps and infrared disinfection lamps are set to sterilize and disinfect the mixture of collected cat litter and excrement from two directions, preventing the generation of odors due to the user's lack of time to change the litter box, and ensuring the hygiene of the environment.

[0027] The working principle of this utility model is as follows: When using the litter box, pour cat litter into the litter box 106, press the power button on the control panel 12 to power the control motherboard 12. The control panel 13 allows selection of timed spray deodorization or sensor-based deodorization, depending on the needs. Simultaneously, a corresponding APP can be downloaded to a terminal device such as a mobile phone or tablet, and paired with the control motherboard 12 via the wireless communication module 122, enabling remote control of the litter box. In the sensor-based deodorization mode, when a pet enters the litter box 106, the four weight sensors 14 detect a change in weight. At this time, no control signal is triggered; monitoring is maintained. After the pet finishes defecating and leaves, a significant weight change occurs again, triggering a start signal from the weight sensors 14 to the control motherboard 12. The main control chip 121 then sends a start signal to the atomizer 61, activating the atomization function. The disinfectant atomized liquid enters the mist guide 251 through the conduit and then enters the spray head 9, spraying out from the spray hole 91 to cover the litter box 106, thereby effectively deodorizing the litter box. The system disinfects and deodorizes pet excrement. When cleaning is needed, the litter changing function can be selected via control panel 13 or control terminal. Drive motor 7 starts, rotating drive gear 8. Drive gear 8 causes the rotating litter box 1 to rotate away from drive motor 7. The litter, along with the excrement, tumbles towards filter screen 102. The excrement is trapped on filter screen 102, while clean litter passes through it into the filtration chamber. During continuous rotation, the excrement eventually falls off filter screen 102. The litter falls into the collection chamber 4 through the cavity of the base frame 21. During each litter change, the UV sterilization lamp 10 and the infrared disinfection lamp 11 will be activated to sterilize and disinfect the excrement that falls into the collection chamber 4 for 10 minutes. After the excrement falls into the collection chamber 4, the drive motor 7 reverses and controls the rotating litter box 1 to reverse and reset. During the reversal process, the clean cat litter will return to the litter box 106 through the filter screen 102 and can be reused. The intelligent automatic spray deodorization combined with one-button litter changing brings a more hygienic environment for pets.
