Description

Technical Field

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

[0002] A cat toilet, also known as a cat litter box, is a container for cats to excrete. Existing cat litter boxes usually include a chamber for pet activities. When in use, cat litter is placed in the chamber. After a trained cat defecates in the pet activity chamber, the cat litter adheres to the feces and wraps the feces into a ball, thereby burying the cat feces. Although many existing cat litters have antibacterial and deodorizing functions, and most cats also have the physiological habit of stirring the cat litter to bury the feces after excretion, the feces will still emit a relatively pungent odor during the excretion process, especially in the home, which not only affects the indoor air and environment, but also easily breeds bacteria, affecting the health of pet cats and cat owners, and needs to be solved urgently. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides a smart deodorizing cat litter box.

[0004] The above invention objectives of the present application are achieved through the following technical solutions: A smart deodorizing cat litter box comprises a cat litter box body, a plasma module and a monitoring sensor, wherein the cat litter box body is used to store cat litter and is provided with a movable door for cats to enter and exit by rotation on one side, the cat litter box body is provided with a first vent, the plasma module and the monitoring sensor are control-connected and are both arranged inside the cat litter box body, the monitoring sensor is used to monitor the gas composition inside the cat litter box body, and the plasma module is used to generate positive and negative ions to deodorize and sterilize the internal space of the cat litter box body.

[0005] By adopting the above technical solution, the cat can freely enter and exit the cat litter box body through the movable door for excretion activities, and after the cat goes to the toilet, the monitoring sensor monitors the gas composition inside the cat litter box body in real time. When the monitoring sensor detects that the odor molecules reach a preset threshold, it will send a signal to the plasma module. The plasma module starts to ionize the gas molecules in the air to produce positive and negative ions, which diffuse into the interior of the cat litter box body and combine with the odor molecules. The chemical structure of the odor molecules can be changed to make them harmless, and the cell walls of bacteria can be destroyed by ions, thereby achieving a sterilization effect. Finally, air circulation is completed through the first vent of the cat litter box body to complete the deodorization process.

When the internal circulation fan is working, the air inside the cat litter box body will enter the internal circulation fan from the opening of the installation cover, and then be output to the second vent through the second air inlet channel, so that the air inside the cat litter box body can continue to pass through the plasma module for continuous deodorization and sterilization. Combined with the setting of the external circulation fan and the first air inlet channel, a two-layer air circulation mechanism is formed inside the cat litter box.

[0021] By adopting the above technical solution, when the infrared sensor senses that the cat has entered the litter box, the infrared sensor sends a signal to the control module, so that the control module controls each device to stop working, thereby avoiding disturbing the cat due to equipment noise and providing the cat with a comfortable toilet environment.

At the same time, the plasma module 2 is arranged at the second vent 8, which can make full use of the power of air flow, and quickly diffuse the positive and negative ions generated by ionization into the inside of the cat litter box body 1, and efficiently deodorize and sterilize the air flowing through the inside. The first air inlet channel 9 is used to guide the external air to the second vent 8, and the plasma module 2 working at the second vent 8 can improve the efficiency of ionization, generate more positive and negative ions faster, and further improve the effect of deodorization and sterilization. The gas after deodorization and sterilization is discharged to the outside through the exhaust port 10 opened on the cat litter box body 1 to complete the air circulation.

[0035] Furthermore, an internal circulation fan 11 is arranged on the installation cover 6, and the installation cover 6 has an opening corresponding to the position of the internal circulation fan 11 and is connected to the internal circulation fan 11, and the internal circulation fan 11 is connected to a second air inlet channel 12, and the second air inlet channel 12 is located between the internal circulation fan 11 and the second vent 8, wherein an additional air circulation loop between the closed cavity and the cat litter box is formed between the internal circulation fan 11, the second air inlet channel 12 and the second vent 8. When the internal circulation fan 11 is working, the air inside the cat litter box body 1 will enter the internal circulation fan 11 from the opening of the installation cover 6, and then pass through the second vent The air inlet channel 12 is output to the second vent 8 so that the air inside the cat litter box body 1 can continue to pass through the plasma module 2 to continuously perform the deodorization and sterilization treatment. Combined with the setting of the external circulation fan 7 and the first air inlet channel 9, 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 preliminary 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 fast 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.

[0036] Furthermore, the first air inlet channel 9 and the second air inlet channel 12 are integrally connected and interconnected, and the first air inlet channel 9 and the second air inlet channel 12 are both arranged in an arc shape. By connecting the first air inlet channel 9 and the second air inlet channel 12 to each other and outputting them together to the second vent 8, the air circulation path can be simplified, and 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. In addition, through the arc-shaped arrangement, the resistance and energy loss in the air flow process can be reduced, so that the air can flow smoothly, reducing the occurrence of eddy currents and turbulence, thereby reducing the noise when the cat litter box is working, and providing a comfortable toilet environment for the pet.

[0037] It should be noted that the monitoring sensor 3 can also be arranged in the first air inlet channel 9 or the second air inlet channel 12. With such an arrangement, when the external circulation fan 7 and the internal circulation fan 11 are working, that is, when the air is in a rapid circulation process, 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.

[0038] In addition, a wind hood 13 is extended from the end of the first air inlet channel 9 and the end of the second air inlet channel 12. The wind hood 13 is arranged on the plasma module 2 and the second vent 8. By setting the wind hood 13, the air passing through the first air inlet channel 9 and the second air inlet channel 12 can be concentrated and guided in the wind hood 13 to improve the deodorization and sterilization efficiency of the plasma module 2.

[0039] Preferably, the first vent 5 is provided with a filter 14 to prevent dust and other debris in the external environment from entering the first vent 5, thereby protecting the internal components of the closed cavity from damage and contamination, and the second vent 8 is provided with multiple and arranged in strips to prevent cat litter, dust and other debris from entering the second vent 8, thereby protecting the internal components of the closed cavity from damage and contamination.

[0040] In addition, in the present 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 supply and to the high-voltage transformer 21, the negative electrode plate 23 is connected to the negative pole of the high-voltage transformer 21 and is provided with a plurality of corona peak columns 25, the positive electrode plate 24 is connected to the positive pole of the high-voltage transformer 21 and is arranged opposite to the negative electrode plate 23, the positive electrode plate 24 is provided with a plurality of corona holes 26 corresponding to the corona peak columns 25, and the corona peak column 25 is located at the center of the corona hole 26, wherein the PCB board 22 is connected to an external power supply to relay transmission to the high-voltage transformer 21, the high-voltage transformer 21 generates high voltage, so that a high-voltage area is formed between the negative electrode plate 23 and the positive electrode plate 24 connected to the negative pole and the positive pole of the high-voltage transformer 21 respectively, and a discharge area is formed at the center of the corona hole 26, when the air contacts the discharge area, ionization will occur, and a large number of positive ions and negative ions will be generated, thereby completing the generation of positive and negative ions.

[0041] It needs to be further explained that the working principle of plasma is to increase the low voltage to positive high voltage and negative high voltage through the boost circuit, and use the positive high voltage and negative high voltage to ionize the air, generating a large amount of positive ion oxygen and negative ion oxygen. The higher the positive and negative voltage output, the greater the number of positive and negative ions generated. The generated positive and negative ions purify the air at the same time. After the positive and negative ions are neutralized with the substances in the air, a huge energy release is instantly generated, and the molecular structure changes quickly, resulting in changes in the bacterial structure or energy conversion, thereby causing the bacteria to die and achieving its bactericidal effect. Since the number of negative ions is much larger than the number of positive ions during the design, the remaining negative ions still float in the air during purification, which can eliminate smoke, dust, and odor, improve air quality, promote human blood circulation, and prevent bacterial regeneration.

[0042] In order to realize the intelligent adjustment and control of the intelligent deodorizing cat litter box, the intelligent deodorizing cat litter box also includes a control module 15, which is arranged on the cat litter box body 1 and is controlled and connected to the monitoring sensor 3, the plasma module 2, the external circulation fan 7 and the internal circulation fan 11. By setting the control module 15, the monitoring sensor 3, the plasma module 2, the external circulation fan 7 and the internal circulation fan 11 can be intelligently coordinated according to the real-time changes of the gas molecules inside the cat litter box. Among them, the specific structural composition and working principle of the control module 15 are common knowledge of technicians in this field and will not be elaborated here.

[0043] Furthermore, an infrared sensor 16 is installed at the bottom of the cover body 6, and the control module 15 is controlled and connected to the infrared sensor 16. The infrared sensor 16 is used to detect the cat inside the cat litter box body 1. When the infrared sensor 16 senses that the cat has entered the cat litter box, the infrared sensor 16 sends a signal to the control module 15, so that the control module 15 controls each device to stop working, thereby avoiding disturbing the cat due to equipment noise and providing a comfortable toilet environment for the cat.

[0044] Preferably, a wire groove 17 is extended on the installation cover 6, and a lead DC board 18 is arranged in 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 position for collecting wires 19 can be provided for various electrical equipment inside the installation cover 6, and the wire groove 17 passes through the cat litter box body 1, and with the lead DC board 18 located in the wire groove 17, the wires 19 can be uniformly electrically connected to the lead DC board 18 to facilitate connection to an external power supply, thereby greatly improving the ease of use of the smart deodorizing cat litter box.

[0045] The implementation principle of an intelligent deodorizing cat litter box in an embodiment of the present application is as follows: during the pet's toileting process, the monitoring sensor 3 arranged 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 odor through data, the control module 15 will send a start-up maximum deodorization signal to the external circulation fan 7, the internal circulation fan 11 and the plasma module 2, 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 preliminary 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 fast 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.

It should be understood by those skilled in the art 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 in the protection scope of this application.
