Description

Technical Field

[0001] This utility model relates to the field of pet equipment technology, specifically to a smart pet toilet flushing system and device. Background Technology

[0002] More and more people are keeping pets these days, mainly cats and dogs.

[0003] Cats and dogs can be trained to use the toilet in designated locations. However, if their excrement is not flushed immediately after they use the toilet, the next person using it will have a poor experience. While infrared sensors can identify whether a pet has entered the toilet and flush accordingly, infrared sensors are prone to misjudgment, causing the toilet to flush empty and wasting water. In existing technologies, such as the Chinese utility model patent with publication number CN212520341U, a smart fully automatic toilet flusher for pets is disclosed. This solution controls flushing through pressure sensing, but sometimes animals may experience constipation when using the toilet. The aforementioned solution cannot determine whether the person using the toilet is a pet, nor can it determine whether the pet has defecated, which can easily lead to misjudgment and waste of water.

[0004] Therefore, we propose a smart pet toilet flushing system and device. Utility Model Content

[0005] One of the technical problems this application aims to solve is that existing methods of controlling flushing using infrared sensors and pressure sensors are prone to misjudgment, resulting in empty flushing of the toilet and wasting water resources.

[0006] To address the aforementioned technical problems, this application provides a smart pet toilet flushing system, including a pressure detection module and an identification module. The pressure detection module includes a pressure sensor, Bluetooth communication, and a battery, used for detecting pressure on objects.

[0007] The pressure sensor is located at the bottom of the toilet seat cover and can be connected to the toilet bowl wall;

The output end of the electric push rod can be connected to the movable plate. An opening is provided on one side of the first protective shell, and an actuating rod is provided on the movable plate. The actuating rod can move vertically within the opening.

[0011] In some embodiments, the actuator is an L-shaped component, with one end of the actuator away from the movable plate located directly above the water tank button.

[0012] In some embodiments, a return spring is also included, with two return springs respectively looped around the outside of the support column. The return springs are located between the bottom surface of the first protective shell and the movable plate, and the movable plate can be moved by the elastic force of the return springs.

[0013] In some embodiments, the interior of the first protective shell is provided with a partition, and the interior space of the first protective shell is divided into a first placement cavity and a second placement cavity by the partition. The supporting column and the movable plate are both located in the first placement cavity. The second protective shell is located directly above the first placement cavity.

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1 to 6The technical solution provided by this utility model is as follows: a smart toilet flushing system for pets, including a pressure detection module and an identification module. The pressure detection module includes a pressure sensor, Bluetooth communication and a battery, and is used to detect the pressure of objects. The pressure sensor is set at the bottom of the toilet seat cover and can be connected to the toilet bowl wall. The identification module includes a microcontroller and a battery, and is used to identify the pet's defecation and urination behavior and to judge the object that generates pressure.

[0031] A smart pet flushing device includes a pressing mechanism 1, which is mounted on the top of a water tank via a mounting plate 101 and an adhesive piece 12. The pressing mechanism 1 is used to operate a flush button, recognize the pet's defecation and urination behaviors, and identify the object generating pressure. The recognition module also includes a recognition camera 5.

[0032] In this embodiment, as Figure 2 and Figure 4 As shown, the adhesive component 12 includes a double-sided adhesive tape 1201 fixed to the bottom of the mounting plate 101. The pressing mechanism 1 also includes a first protective shell 2, which is located on the top of the mounting plate 101. A second protective shell 3 is connected to the top of the first protective shell 2. An electric push rod 13 is installed inside the second protective shell 3. Two symmetrically distributed support columns 16 are provided on one side inside the first protective shell 2. A movable plate 18 is slidably sleeved on the two support columns 16. The output end of the electric push rod 13 can be connected to the movable plate 18. An opening 10 is provided on one side of the first protective shell 2. An actuating rod 4 is provided on the movable plate 18. The actuating rod 4 can move vertically within the opening 10. The recognition camera 5 is located on the outer surface of the first protective shell 2. The actuating rod 4 is an L-shaped component. The end of the actuating rod 4 away from the movable plate 18 is located directly above the water tank button.

[0033] It also includes a return spring 17. Two return springs 17 are respectively looped around the outside of the support column 16. The return springs 17 are located between the bottom surface of the first protective shell 2 and the moving plate 18. The moving plate 18 can be moved by the elastic force of the return springs 17.

[0034] When the operation is initiated, the electric push rod 13 is energized and pushes down the moving plate 18. At the same time, the actuator 4 moves down and gradually pushes the water tank button. When the electric push rod 13 reaches its maximum output limit, the actuator 4 presses the water tank button to the lowest position, at which point the water tank flushing function is activated and flushing is completed. After flushing, the electric push rod 13 will retract after reaching its maximum output limit until it stops retracting completely. Because the return spring 17 is compressed while the moving plate 18 is being pressed down, the return spring 17 has rebound potential energy to be released. When the electric push rod 13 is retracted, the return spring 17 will act on the moving plate 18 to reset the actuator 4 for the next use.

[0035] In this embodiment, as Figure 2 and Figure 4 As shown, the interior of the first protective shell 2 is equipped with a partition, which divides the internal space of the first protective shell 2 into a first placement cavity 14 and a second placement cavity 15. The support column 16 and the movable plate 18 are both located in the first placement cavity 14. The second protective shell 3 is located directly above the first placement cavity 14. The second placement cavity 15 is empty. A sealing cover 11 is hinged on the first protective shell 2 and directly above the second placement cavity 15. Opening the sealing cover 11 allows the spare battery or other items in the device to be placed in the second placement cavity 15, thus having the function of storing items.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, a limiting edge 8 is provided on one side of the top of the mounting plate 101. A pair of slide rails 6 are provided on the top surface of the mounting plate 101. A pair of slide blocks 7 are provided at the bottom of the first protective shell 2, which respectively cooperate with the slide rails 6. The first protective shell 2 is slidably connected to the slide rails 6. A limiting bolt 9 is provided at the end of the mounting plate 101 away from the limiting edge 8. This setting provides adjustability for the first protective shell 2. When the position of the actuator 4 is forward or backward, the pressing end of the actuator 4 is located at the edge of the water tank button, making it difficult to press down. The button may cause flushing failure. This problem can be avoided by moving the first protective shell 2 horizontally, so that the pressing end of the actuator 4 is in the middle position of the water tank button, achieving a stable pressing action. There is sliding damping between the slide rail 6 and the slide block 7, which can keep the slide block 7 stable when it is not subjected to external force, reducing the probability of self-movement. Furthermore, by removing the limiting bolt 9, the first protective shell 2 and the mounting plate 101 can be separated, which is convenient for charging the battery of the power module inside the device or for its maintenance.

[0037] In this embodiment, the pressure sensor is wirelessly connected to the microcontroller, and the microcontroller is wirelessly connected to the electric push rod 13.

[0038] The usage process is as follows:

[0039] S1. The pet enters the toilet and sits down to relieve itself. At this time, the pressure sensor in the pressure detection module detects the pressure exerted by the pet and transmits the pressure signal value n to the identification module via Bluetooth. The identification module judges whether the signal value n is within the pet's weight range n1 to n2. If n1≤n≤n2, it is determined that the pet is relieving itself and proceeds to the next stage; if n≤n1 or n≥n2, it is determined that it is not a pet, and flushing is not performed, and the process ends.

[0040] S2. Wake-up recognition function: By recognizing the image data captured by camera 5, the current pet's actions and feature values ​​are matched with the large model. If the match is unsuccessful, it is determined that the pet has not performed toilet work, and no flushing command is sent to the actuator, and the process ends.

[0041] S3. If the matching is successful, confirm that the pet has defecate or urinated, and wait for the periodic pressure signal value provided by the pressure detection module. When the received pressure signal value is 0, the identification module sends a flushing command to the pressing mechanism 1 via Bluetooth. The actuator 4 in the pressing mechanism 1 presses the water tank button, the water tank completes the flushing, and the process ends.

[0042] S4. After the pressing mechanism 1 completes the pressing action, the actuator 4 resets and waits for the next instruction.

[0043] The implementation principle of the intelligent pet flushing device in this application embodiment is as follows: When the electric push rod 13 is energized, it pushes down the moving plate 18. At the same time, the actuator 4 moves down and gradually pushes the water tank button. When the electric push rod 13 reaches its maximum output limit, the actuator 4 presses the water tank button to the lowest position. At this time, the flushing function of the water tank has been activated, and flushing can be completed. After flushing is completed, the electric push rod 13 will retract after reaching its maximum output limit until it stops retracting completely. Because the return spring 17 is compressed at the same time as the moving plate 18 is pressed down, the return spring 17 has rebound potential energy to be released. When the electric push rod 13 is retracted, the return spring 17 will act on the moving plate 18 to reset the actuator 4 for the next use.

[0044] Example 2:

[0045] Please see Figure 7 The technical solution provided by this utility model is as follows:

[0046] Unlike Embodiment 1, this solution provides another implementation of the adhesive component 12: the adhesive component 12 includes two adhesive hook and loop fasteners 1202 disposed on the bottom of the mounting plate 101 and adhered to each other. The two adhesive hook and loop fasteners 1202 are respectively adhered and fixed to the top of the water tank and the bottom of the mounting plate 101. Installation only requires the two adhesive hook and loop fasteners 1202 to adhere to each other. In subsequent use, if it is necessary to adjust the installation position of the mounting plate 101, the adhesive hook and loop fasteners 1202 can be peeled off, the mounting plate 101 can be moved horizontally, and the position can be adjusted so that the remaining parts of the adhesive hook and loop fasteners 1202 after horizontal movement adhere to each other, which improves practicality, facilitates real-time adjustment by the user, and makes use more convenient.
