Description

A smart deodorizing cat litter box Technical Field

[0001] This invention relates to the technical field of pet products, and in particular to an intelligent deodorizing cat litter box. Background Technology

[0002] A litter box, also known as a cat litter box, is a container for cats to excrete waste. Existing litter boxes typically include a chamber for the pet to move around in. When in use, cat litter is placed in this chamber. A trained cat defecates in the chamber, and the litter adheres to the feces, tucking it into a ball and burying it. Although many existing cat litters have antibacterial and deodorizing functions, and most cats have the physiological habit of digging in the litter to bury their waste, feces still emit a rather pungent odor during defecation, especially indoors. This not only affects indoor air quality and the environment but also easily breeds bacteria, impacting the health of both the cat and its owner, a problem that urgently needs to be addressed. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this application provides an intelligent deodorizing cat litter box.

[0004] The above-mentioned inventive objective of this application is achieved through the following technical solutions:

[0005] A smart deodorizing cat litter box includes a litter box body, a plasma module, and a monitoring sensor. The litter box body is used to store cat litter and has a rotating door on one side for cats to enter and exit. The litter box body has a first ventilation opening. The plasma module and the monitoring sensor are controlled to be connected and are both located inside the litter box body. The monitoring sensor is used to monitor the gas composition inside the litter box body. The plasma module is used to generate positive and negative ions to deodorize and sterilize the internal space of the litter box body.

[0006] By adopting the above technical solution, cats can freely enter and exit the litter box through the movable door to relieve themselves. After the cat uses the litter box, the monitoring sensor monitors the gas composition inside the litter box in real time. When the monitoring sensor detects odor molecules reaching a preset threshold, it sends a signal to the plasma module. The plasma module is activated to ionize the gas molecules in the air to generate positive and negative ions, which diffuse into the litter box and combine with the odor molecules. This alters the chemical structure of the odor molecules, making them harmless. The ions also destroy the cell walls of bacteria, thus achieving a sterilization effect. Finally, air circulation is completed through the first vent of the litter box to finish the odor removal process.

[0007] In a preferred embodiment, this application can be further configured as follows: an installation cover is provided inside the litter box body, an external circulation fan is provided on the installation cover, the external circulation fan is connected to the first ventilation port, the installation cover has a second ventilation port, the external circulation fan is connected to a first air inlet channel, the first air inlet channel is located between the external circulation fan and the second ventilation port, the plasma module is disposed inside the installation cover and located at the second ventilation port, the installation cover and the litter box body form a closed cavity for air circulation, and the litter box body has an exhaust port.

[0008] By adopting the above technical solution, a complete air circulation system is formed through the design of an external circulation fan, a first air inlet channel, a second vent, and an exhaust vent. The external circulation motor is installed at the first vent, which can drive external air into the closed cavity and the litter box body, so that the air inside the litter box can be continuously refreshed. At the same time, the plasma module is set at the second vent, which can make full use of the power of air flow to quickly diffuse the positive and negative ions generated by ionization into the interior of the litter box body, and perform efficient deodorization and sterilization treatment on the air flowing inside. The first air inlet channel is used to concentrate and guide external air to the second vent. Combined with the plasma module working at the second vent, it can improve the ionization efficiency, generate positive and negative ions faster and more, and further improve the deodorization and sterilization effect. The air after deodorization and sterilization treatment is discharged to the outside through the exhaust vent on the litter box body, completing the air circulation.

[0009] In a preferred embodiment, this application may be further configured such that: an internal circulation fan is provided on the mounting cover, the mounting cover has an opening corresponding to and connected to the internal circulation fan, and the internal circulation fan is connected to a second air inlet channel, the second air inlet channel being located between the internal circulation fan and the second vent.

[0010] By adopting the above technical solution, an additional air circulation loop is formed between the internal circulation fan, the second air inlet channel, and the second vent, connecting the closed cavity and the litter box. When the internal circulation fan is working, it draws air from inside the litter box into the internal circulation fan through the opening of the cover, and then outputs it to the second vent through the second air inlet channel. This allows the air inside the litter box to continuously pass through the plasma module for continuous deodorization and sterilization. Combined with the external circulation fan and the first air inlet channel, a two-layer air circulation mechanism is formed inside the litter box. The external circulation fan is responsible for introducing external air into the litter box and performing initial air renewal, and for diffusing the ionized positive and negative ions into the litter box. The internal circulation fan is responsible for rapid and efficient air circulation inside the litter box to ensure that the air inside the litter box is continuously purified.

[0011] In a preferred embodiment, this application can be further configured such that the first air inlet channel and the second air inlet channel are integrally connected and interconnected, and both the first air inlet channel and the second air inlet channel are arranged in an arc shape.

[0012] By adopting the above technical solution, the first air intake channel and the second air intake channel are interconnected and jointly output to the second vent, which simplifies the air circulation path and allows for unified output to the plasma module at the second vent for deodorization and sterilization. This improves the efficiency of air circulation and the uniformity of deodorization and sterilization. Furthermore, the arc-shaped design reduces air resistance and energy loss during airflow, allowing air to flow smoothly and reducing the occurrence of eddies and turbulence. This reduces the noise of the litter box during operation and provides a comfortable toilet environment for pets.

[0013] In a preferred embodiment, this application may be further configured such that: a wind shroud extends from the end of the first air inlet channel and the end of the second air inlet channel, and the wind shroud covers the plasma module and the second ventilation opening.

[0014] By adopting the above technical solution and setting up a fan hood, the air passing through the first air intake channel and the second air intake channel can be concentrated and guided into the fan hood, thereby improving the deodorization and sterilization efficiency of the plasma module.

[0015] In a preferred embodiment, this application may be further configured such that: the first vent is provided with a filter screen, and the second vent is provided in multiple forms arranged in a strip.

[0016] By adopting the above technical solution, it is possible to prevent dust and other debris from entering the first ventilation opening, protecting the internal components of the sealed cavity from damage and contamination, and to prevent cat litter, dust and other debris from entering the second ventilation opening, protecting the internal components of the sealed cavity from damage and contamination.

[0017] In a preferred embodiment, this application can be further configured as follows: the plasma module includes a high-voltage transformer, a PCB board, a negative electrode plate, and a positive electrode plate. The PCB board is electrically connected to an external power source and to the high-voltage transformer. The negative electrode plate is connected to the negative terminal of the high-voltage transformer and has a plurality of corona peaks. The positive electrode plate is connected to the positive terminal of the high-voltage transformer and is positioned opposite the negative electrode plate. The positive electrode plate has a plurality of corona holes corresponding to the corona peaks, and the corona peaks are located at the center of the corona holes.

[0018] By adopting the above technical solution, the PCB board is connected to an external power supply to relay the high voltage transformer. The high voltage transformer generates high voltage, which forms a high voltage zone between the negative electrode plate and the positive electrode plate, which are respectively connected to the negative and positive terminals of the high voltage transformer. A discharge zone is formed at the center of the corona hole. When air comes into contact with the discharge zone, ionization will occur, generating a large number of positive and negative ions, thereby completing the generation of positive and negative ions.

[0019] In a preferred embodiment, the present application may be further configured such that the intelligent deodorizing litter box also includes a control module, the control module being disposed on the litter box body and controlled and connected to the monitoring sensor, the plasma module, the external circulation fan and the internal circulation fan.

[0020] By adopting the above technical solution and setting up a control module, intelligent coordination can be achieved between the monitoring sensor, plasma module, external circulation fan and internal circulation fan based on the real-time changes of gas molecules inside the litter box.

[0021] In a preferred embodiment, this application can be further configured such that: an infrared sensor is provided at the bottom of the mounting cover, and the control module is connected to the infrared sensor; the infrared sensor is used to detect the cat inside the litter box body.

[0022] By adopting the above technical solution, when the infrared sensor detects that the cat has entered the litter box, the infrared sensor sends a signal to the control module, so that the control module controls the devices to stop working, thereby avoiding disturbing the cat due to the noise of the devices and providing the cat with a comfortable toilet environment.

[0023] In a preferred embodiment, this application may be further configured such that: a wire groove extends from the mounting cover, a DC lead board is disposed within the wire groove, and the wire groove extends through the litter box body to the outside.

[0024] By adopting the above technical solution and setting up the cable tray, a location can be provided for the collection of cables for various electrical devices inside the installation cover. The cable tray runs through the cat litter box body, and with the lead DC board located in the cable tray, all cables can be electrically connected to the lead DC board to facilitate connection to external power, thereby greatly improving the ease of use of the smart deodorizing cat litter box.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Cats can freely enter and exit the litter box through the movable door to relieve themselves. While the cat is relieving itself, the monitoring sensor monitors the gas composition inside the litter box in real time. When the monitoring sensor detects odor molecules reaching a preset threshold, it sends a signal to the plasma module. The plasma module is activated to ionize the gas molecules in the air, generating positive and negative ions. These ions diffuse into the interior of the litter box and combine with the odor molecules, changing their chemical structure and making them harmless. The ions also destroy the cell walls of bacteria, thus achieving a sterilization effect. Finally, air circulation is completed through the first vent in the litter box to finish the odor removal process.

[0027] 2. A complete air circulation system is formed through the design of an external circulation fan, a first air inlet channel, a second vent, and an exhaust vent. The external circulation motor is installed at the first vent, which drives external air into the enclosed cavity and the litter box body, so that the air inside the litter box can be continuously refreshed. At the same time, the plasma module is set at the second vent, which can make full use of the power of air flow to quickly diffuse the positive and negative ions generated by ionization into the interior of the litter box body, and perform efficient deodorization and sterilization treatment on the air flowing inside. The first air inlet channel is used to concentrate and guide external air to the second vent. Combined with the plasma module working at the second vent, it can improve the ionization efficiency, generate positive and negative ions faster and more, and further improve the deodorization and sterilization effect. The air after deodorization and sterilization treatment is discharged to the outside through the exhaust vent on the litter box body, completing the air circulation.

[0028] 3. An additional air circulation loop is formed between the internal circulation fan, the second air intake channel, and the second vent, creating a closed cavity between the litter box and the litter box. When the internal circulation fan is working, it draws air from inside the litter box into the fan through the opening of the cover, and then outputs it to the second vent via the second air intake channel. This ensures that the air inside the litter box continuously passes through the plasma module for continuous deodorization and sterilization. Combined with the external circulation fan and the first air intake channel, a two-layer air circulation mechanism is formed inside the litter box. The external circulation fan is responsible for introducing external air into the litter box and performing initial air renewal, and for diffusing the ionized positive and negative ions into the litter box. The internal circulation fan is responsible for rapid and efficient air circulation inside the litter box to ensure that the air inside the litter box is continuously purified.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein.

[0037] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0038] The following description, with reference to the accompanying drawings, describes an intelligent deodorizing cat litter box according to this application.

[0039] Referring to Figures 1 to 5, the litter box body 1, plasma module 2, and monitoring sensor 3 are shown. The litter box body 1 is used to store cat litter and has a rotating door 4 on one side for the cat to enter and exit. The litter box body 1 has a first ventilation opening 5. The plasma module 2 and the monitoring sensor 3 are connected and both are located inside the litter box body 1. The monitoring sensor 3 is used to monitor the gas composition inside the litter box body 1. The plasma module 2 is used to generate positive and negative ions to deodorize and sterilize the internal space of the litter box body 1. The cat can freely enter and exit the litter box body 1 through the rotating door 4 to defecate. After the cat uses the litter box, the monitoring sensor 3 monitors the gas composition inside the litter box body 1 in real time. When the monitoring sensor 3 detects odor molecules reaching a preset threshold, it sends a signal to the plasma module 2. The plasma module 2 then activates to ionize the gas molecules in the air, generating positive and negative ions. These ions diffuse into the interior of the litter box body 1 and combine with the odor molecules, altering their chemical structure and rendering them harmless. The ions also destroy the cell walls of bacteria, achieving a sterilization effect. Finally, air circulation is achieved through the first vent 5 of the litter box body 1, completing the odor removal process.

[0040] Preferably, the litter box body 1 has an internal mounting cover 6, on which an external circulation fan 7 is installed. The external circulation fan 7 is connected to a first ventilation opening 5. The mounting cover 6 has a second ventilation opening 8, and the external circulation fan 7 is connected to a first air inlet channel 9, which is located between the external circulation fan 7 and the second ventilation opening 8. The plasma module 2 is installed inside the mounting cover 6 and located at the second ventilation opening 8. The mounting cover 6 and the litter box body 1 form a closed cavity for air circulation. The litter box body 1 has an exhaust vent 10. Through the design of the external circulation fan 7, the first air inlet channel 9, the second ventilation opening 8, and the exhaust vent 10, a complete air circulation system is formed. The external circulation motor is installed at the first ventilation opening 5. The system drives external air into the enclosed cavity and the litter box body 1, ensuring continuous air renewal within the litter box. Simultaneously, the plasma module 2, located at the second vent 8, fully utilizes the power of airflow to rapidly diffuse the positive and negative ions generated by ionization into the litter box body 1, effectively deodorizing and sterilizing the air flowing through it. The first air inlet channel 9 guides external air to the second vent 8, which, combined with the plasma module 2 operating at the second vent 8, enhances ionization efficiency, generating more and faster positive and negative ions, further improving the deodorization and sterilization effect. The deodorized and sterilized air is then exhausted to the outside through the exhaust vent 10 on the litter box body 1, completing air circulation.

[0041] Furthermore, an internal circulation fan 11 is provided on the mounting cover 6. The mounting cover 6 has an opening corresponding to and connected to the internal circulation fan 11. The internal circulation fan 11 is connected to a second air inlet channel 12, which is located between the internal circulation fan 11 and the second vent 8. The internal circulation fan 11, the second air inlet channel 12, and the second vent 8 form an additional air circulation loop between the closed cavity and the litter box. When the internal circulation fan 11 is working, it draws air from inside the litter box body 1 into the internal circulation fan 11 through the opening of the mounting cover 6, and then through the second vent 8... The air intake duct 12 outputs to the second vent 8 so that the air inside the litter box body 1 can continuously pass through the plasma module 2 for continuous deodorization and sterilization. Combined with the external circulation fan 7 and the first air intake duct 9, a two-layer air circulation mechanism is formed inside the litter box. The external circulation fan 7 is responsible for introducing external air into the litter box body 1 and performing initial air renewal, and diffusing the ionized positive and negative ions into the litter box body 1. The internal circulation fan 11 is responsible for rapid and efficient air circulation inside the litter box body 1 to ensure that the air inside the litter box body 1 can be continuously purified.

[0042] Furthermore, the first air intake channel 9 and the second air intake channel 12 are integrally connected and interconnected. Both the first air intake channel 9 and the second air intake channel 12 are arc-shaped. By connecting the first air intake channel 9 and the second air intake channel 12 and outputting them together to the second vent 8, the air circulation path can be simplified. The air can be uniformly output to the plasma module 2 at the second vent 8 for deodorization and sterilization, thereby improving the efficiency of air circulation and the uniformity of deodorization and sterilization. Moreover, the arc-shaped design can reduce the resistance and energy loss during air flow, allowing the air to flow smoothly and reducing the occurrence of eddies and turbulence, thereby reducing the noise of the litter box during operation and providing a comfortable toilet environment for pets.

[0043] It should be noted that the monitoring sensor 3 can also be set in the first air intake channel 9 or the second air intake channel 12. With this setting, when the external circulation fan 7 and the internal circulation fan 11 are working, that is, when the air is circulating rapidly, the monitoring sensor 3 can detect the composition of the air around the plasma module 2 in the first time, thereby improving the response efficiency of the monitoring sensor 3 and the deodorization and sterilization efficiency of the plasma module 2.

[0044] In addition, a hood 13 is provided at the end of the first air intake channel 9 and the end of the second air intake channel 12. The hood 13 covers the plasma module 2 and the second ventilation port 8. By providing the hood 13, the air passing through the first air intake channel 9 and the second air intake channel 12 can be concentrated and guided into the hood 13 to improve the deodorization and sterilization efficiency of the plasma module 2.

[0045] Preferably, the first vent 5 is provided with a filter screen 14 to prevent dust and other debris from entering the first vent 5 and to protect the internal components of the enclosed cavity from damage and contamination. The second vent 8 is provided in multiple strips to prevent cat litter, dust and other debris from entering the second vent 8 and to protect the internal components of the enclosed cavity from damage and contamination.

[0046] Furthermore, in this embodiment, the plasma module 2 includes a high-voltage transformer 21, a PCB board 22, a negative electrode plate 23, and a positive electrode plate 24. The PCB board 22 is electrically connected to an external power source and to the high-voltage transformer 21. The negative electrode plate 23 is connected to the negative terminal of the high-voltage transformer 21 and is provided with a plurality of corona peaks 25. The positive electrode plate 24 is connected to the positive terminal of the high-voltage transformer 21 and is positioned opposite the negative electrode plate 23. The positive electrode plate 24 has a plurality of corona holes 26 corresponding to the corona peaks 25. The corona peaks 25 are located at the center of the corona holes 26. The PCB board 22 is connected to an external power source to relay transmission to the high-voltage transformer 21. The high-voltage transformer 21 generates high voltage, which forms a high-voltage zone between the negative electrode plate 23 and the positive electrode plate 24, which are respectively connected to the negative and positive terminals of the high-voltage transformer 21. A discharge zone is formed at the center of the corona holes 26. When air comes into contact with the discharge zone, ionization will occur, generating a large number of positive and negative ions, thereby completing the generation of positive and negative ions.

[0047] It needs further explanation that the working principle of plasma is to boost a low voltage to positive and negative high voltages through a boost circuit. These high voltages ionize the air, generating a large number of positive and negative oxygen ions. The higher the output voltage, the greater the number of positive and negative ions produced. The generated positive and negative ions simultaneously purify the air. The neutralization of these ions with airborne substances instantly releases a huge amount of energy, rapidly altering the molecular structure and causing changes in bacterial structure or energy conversion, leading to bacterial death and achieving its bactericidal effect. Because the design ensures a much larger number of negative ions than positive ions, the remaining negative ions float in the air after purification, helping to eliminate smoke, dust, and odors, improve air quality, promote blood circulation, and prevent bacterial regeneration.

[0048] To achieve intelligent adjustment and control of the intelligent deodorizing litter box, the intelligent deodorizing litter box also includes a control module 15. The control module 15 is set in the litter box body 1 and is connected to the monitoring sensor 3, plasma module 2, external circulation fan 7 and internal circulation fan 11. By setting the control module 15, the monitoring sensor 3, plasma module 2, external circulation fan 7 and internal circulation fan 11 can intelligently coordinate according to the real-time changes of gas molecules inside the litter box. The specific structure and working principle of the control module 15 are common knowledge to those skilled in the art and will not be described in detail here.

[0049] Furthermore, an infrared sensor 16 is installed at the bottom of the mounting cover 6. The control module 15 is connected to the infrared sensor 16. The infrared sensor 16 is used to detect the cat inside the litter box body 1. When the infrared sensor 16 detects that the cat has entered the litter box, the infrared sensor 16 sends a signal to the control module 15, so that the control module 15 controls all devices to stop working, thereby avoiding disturbing the cat due to the noise of the devices and providing the cat with a comfortable toilet environment.

[0050] Preferably, a wire groove 17 extends from the mounting cover 6, and a lead DC board 18 is installed inside the wire groove 17. The wire groove 17 passes through the cat litter box body 1 to the outside. By setting the wire groove 17, a location can be provided for the collection of wires 19 of various electrical devices inside the mounting cover 6. Furthermore, since the wire groove 17 passes through the cat litter box body 1, and is paired with the lead DC board 18 located in the wire groove 17, all wires 19 can be electrically connected to the lead DC board 18 to facilitate connection to external power, thereby greatly improving the ease of use of the intelligent deodorizing cat litter box.

[0051] The implementation principle of an intelligent deodorizing cat litter box according to an embodiment of this application is as follows: During the pet's toilet use, the monitoring sensor 3 installed inside the cat litter box body 1 senses the data of the internal environment of the cat litter box in real time, such as temperature, humidity, and odor concentration. When the monitoring sensor 3 detects the presence of an odor through the data, the control module 15 sends a signal to the external circulation fan 7, the internal circulation fan 11, and the plasma module 2 to start maximizing deodorization, so that a two-layer air circulation mechanism is formed inside the cat litter box. The external circulation fan 7 is responsible for introducing external air into the cat litter box body 1 and performing initial air renewal, and diffusing the ionized positive and negative ions into the cat litter box body 1. The internal circulation fan 11 is responsible for performing rapid and efficient air circulation inside the cat litter box body 1 to ensure that the air inside the cat litter box body 1 can be continuously purified. After the monitoring sensor 3 confirms that there is no odor in the cat litter box, the control module 15 controls the external circulation fan 7, the internal circulation fan 11, and the plasma module 2 to switch to standby mode.

[0052] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
