Description

Technical Field

[0001] This utility model belongs to the field of pet supplies and equipment technology, specifically, it relates to an intelligent cat toilet. Background Technology

[0002] In the pet ownership industry, smart litter boxes bring many conveniences to cat owners, but their functionality still has room for improvement. Take patent CN112470951A as an example. This patent focuses on the automatic cleaning mechanism of smart litter boxes, using a specific structural design to separate and clean cat litter from feces. However, in practical applications, this design is not very effective at cleaning fine clumps of urine and small fecal particles. These tiny particles easily get stuck in the gaps of the cleaning structure and cannot be effectively separated, leading to litter waste and, over time, the growth of bacteria and odors, affecting the cleanliness and user experience of the litter box. Furthermore, the cleaning structure in this patent agitates the litter considerably during operation, resulting in uneven litter placement after cleaning, which may cause discomfort for cats when they use it again.

[0003] Looking at patent CN216722573U, it focuses on optimizing the overall structure of the cat litter box, improving the space layout to some extent. However, it has significant shortcomings in safety protection. Its anti-pinch detection device is not sensitive enough; when a cat accidentally enters while the ball chamber is rotating, it cannot detect and brake in time, greatly increasing the risk of pinching the pet. In addition, the deodorization method of this patent is relatively simple, relying only on simple activated carbon adsorption, which is difficult to completely eliminate the strong odor produced by a large amount of feces, resulting in a poor user environment. Furthermore, its litter capacity is limited, its battery life is poor, and the litter filling process lacks precise control, easily leading to insufficient or excessive litter filling, causing inconvenience to users.

[0004] Existing smart litter boxes generally suffer from a lack of privacy protection, as the cameras operate continuously, easily infringing on user privacy. Furthermore, the device's status feedback is untimely and incomplete, preventing users from obtaining real-time information on the litter box's operation, litter volume, and waste collection tank status.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This utility model, through the coordinated design of the filter screen, transfer area, and litter storage area in the ball chamber assembly, enables the filter screen to effectively separate fecal clumps from cat litter during the automatic cleaning process. It has a better filtering effect, especially for fine urine and litter clumps and small fecal particles that are difficult to handle in the prior art, reducing the situation where small particles get stuck in the gaps of the cleaning structure and reducing cat litter waste. At the same time, when the ball chamber assembly rotates in the reverse direction, the cat litter in the transfer area can flow back evenly to the litter storage area, solving the problem of uneven cat litter repositioning in the prior art, which causes discomfort to the cat's paws and improving the cat's user experience.

[0026] 2. This utility model employs left / right micro-switch sensors in conjunction with left / right anti-pinch components. The left and right anti-pinch components are fixed by flexible structural parts, enabling sensitive detection of even weak clamping forces. When a cat accidentally enters the rotating ball chamber assembly, potentially causing injury, braking is immediately triggered. This solves the problem of insufficient sensitivity in anti-pinch detection in existing technologies, significantly reducing the risk of pet injury and improving the safety of the equipment.

[0027] 3. This utility model adopts a method of replacing the fresh air deodorization component with the ozone deodorization component: the fresh air deodorization component works continuously, filtering and expelling odors from the fecal collection chamber through the filter cotton module; when the odor concentration is high, the ozone deodorization component is activated, using the strong oxidizing properties of ozone to enhance deodorization, solving the defect of existing deodorization methods that are difficult to eliminate strong odors, and effectively improving the usage environment.

[0028] 4. This utility model uses a cat litter balance detection sensor to monitor the cat litter balance in real time, and works with a litter adding motor to drive the litter adding impeller to precisely control the amount of litter added. The litter adding effect is verified by comparing data before and after adding litter, avoiding insufficient or excessive litter addition. At the same time, the reasonable design of the litter adding chamber increases the cat litter loading capacity, solves the problems of poor battery life and inaccurate litter adding control in the prior art, reduces the frequency of user operation, and improves the convenience of use.

[0029] 5. This utility model monitors the cat's status in real time through an external camera, and only activates the internal camera when the cat approaches, with the working status displayed by a corresponding indicator light, thus avoiding the privacy invasion problem caused by the continuous operation of cameras in the prior art; at the same time, the angle design of the internal and external cameras ensures the complete monitoring range, taking into account both monitoring needs and privacy protection.

[0030] 6. This utility model uses the weighing structure of the base assembly and the cat litter balance detection sensor to collect information such as the working status of the equipment, the remaining cat litter balance, and the status of the waste collection chamber in real time. This information is then fed back to the user terminal through the main control system, solving the problem of untimely and incomplete equipment status feedback in the prior art. This allows users to keep track of the equipment status in real time and improves the ease of use. Attached Figure Description

[0073] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0074] like Figure 1 As shown, this utility model discloses an intelligent cat toilet, including a base assembly 1, a top cover assembly 2, a ball chamber assembly 3, a sand filling assembly 4, a waste collection chamber 5, a deodorizing assembly, an anti-pinch structure 8, and a monitoring module 10.

[0075] like Figure 2-9 As shown, the base assembly 1 serves as the bracket base for the sphere chamber assembly 3. The base assembly 1 includes an upper part 11 and a lower part 12. The upper part 11 and the lower part 12 are set with an overlapping structure, which can stably connect the upper part 11 and the lower part 12 and provide a stable foundation for the entire weighing module. A weighing structure 13 and a positioning structure 14 are provided between the upper part 11 and the lower part 12. The weighing structure 13 is arranged at the four corners of the base assembly 1 to ensure the uniformity and accuracy of weighing. The positioning structure 14 is arranged on the left and right sides of the base assembly 1 to achieve accurate positioning of the upper part 11 and the lower part 12.

[0076] The weighing structure 13 includes a weighing sensor 131, a weighing foot support pad 132, a weighing foot support bracket 133, a weighing foot 134, and a support foot 135. Weighing feet 134 are fixedly installed at the bottom four corners of the upper part 11, and weighing sensors 131 are fixedly installed at the bottom of the weighing feet 134. The weighing sensors 131 can accurately detect the pressure transmitted by the weighing feet 134. Support feet 135 are fixedly installed at the top four corners of the lower part 12, and weighing foot support brackets 133 are fixedly installed at the top of the support feet 135. A weighing foot support pad 132 is provided at the top center of the weighing foot support bracket 133.

[0077] The weighing foot support bracket 133 includes a support column 1331, elastic arms 1332, and connecting arc arms 1333. Three elastic arms 1332 are arranged in a ring around the top periphery of the support column 1331. The elastic arms 1332 are bow-shaped and have good elastic deformation capability. One end of the multiple elastic arms 1332 is fixedly connected to the support column 1331, and the other end of the multiple elastic arms 1332 is fixed in series by the connecting arc arms 1333. Thus, when the upper part 11 is subjected to load by the weighing sensor 131 on the support column 1331 and deflection occurs, the elastic arms 1332 can perform elastic deformation to ensure that the heavy load does not change and ensure the accuracy of weighing.

[0078] The positioning structure 14 includes positioning feet 141, positioning bracket feet 142, positioning grooves 143, and weighing catches 144. Positioning feet 141 are installed on both the left and right sides of the bottom of the upper part 11. The positioning feet 141 are convex. The top of the positioning bracket feet 142 is provided with a positioning groove 143. The positioning feet 141 and the positioning grooves 143 are inserted into each other to realize the positioning between the upper part 11 and the lower part 12. The top of the positioning feet 141 is fitted with a weighing catch 144. The weighing catch 144 is umbrella-shaped, and a gap is provided between the weighing catch 144 and the top surface of the positioning groove 143. This gap can effectively prevent mechanical locking and ensure the normal operation of the equipment.

[0079] like Figure 1 As shown, the upper cover assembly 2 is located above the base assembly 1. The upper cover assembly 2 and the base assembly 1 form a cabin. The tilt angle of the cabin axis ranges from 10 to 45 degrees, and at least two Hall sensors are installed on the inner wall of the cabin. One Hall sensor is set on the rotation path of the sphere assembly 3 at its maximum rotation position. It is used to detect whether the sphere assembly 3 reaches the maximum rotation position when rotating counterclockwise during the cleaning process. When the sphere assembly 3 is detected to have reached this position, a signal is output to control the sphere assembly 3 to rotate in the opposite direction. The other Hall sensor is set on the rotation path of the sphere assembly 3 at its initial position. It is used to detect whether the sphere assembly 3 returns to the initial state when rotating in the opposite direction. When the sphere assembly 3 is detected to have returned to the initial position, a signal is output to control the sphere assembly 3 to stop rotating.

[0080] like Figure 10 and 11As shown, the ball chamber assembly 3 is rotatably disposed within the chamber cavity formed by the upper cover assembly 2 and the base assembly 1, thereby storing the cat litter placed in the ball chamber assembly 3 and preventing the cat litter from overflowing from the ball chamber assembly 3 due to its rotation during cleaning. The ball chamber assembly 3 includes a ball chamber upper cover 31, a ball chamber middle cover 32, a filter support 33, a filter 34, a ball chamber pad 35, a ball chamber lower cover 36, a circular gear 37, and a ball chamber poop outlet 38. A litter filling window is provided at the top of the ball chamber upper cover 31. During the cleaning process, the ball chamber rotates to the bottom of the base assembly 1, serving as a litter box outlet. The ball chamber top cover 31 and the ball chamber middle cover 32 are connected to form a cup-shaped chamber. A circular gear 37 is fixedly installed at the rear end of the cup-shaped chamber. A motor is installed inside the base assembly 1, and a small gear is installed at the output end of the drive motor. The small gear meshes with the circular gear 37, thereby driving the ball chamber assembly 3 to rotate, completing the automatic cleaning and leveling of the cat litter. A filter support 33 is fixedly installed at the bottom of the ball chamber top cover 31. A filter screen 34 is fixedly installed on the left side. When the ball chamber assembly 3 rotates for cleaning, the filter screen 34 separates the mixture of feces and cat litter. The feces fall into the collection chamber 5 through the channel. A transfer area is formed between the filter screen support 33 and the inner wall of the ball chamber top cover 31. The transfer area is used by the filter screen 34 to store the filtered cat litter, which is convenient for subsequent recycling. A spoon-shaped ball chamber lower cover 36 is fixedly installed at the bottom of the ball chamber middle cover 32. A ball chamber pad 35 is placed on the ball chamber lower cover 36. The ball chamber pad 35 is made of silicone material. The chamber pad 35 is fixedly installed on the ball chamber cover 32 by screws. The ball chamber pad 35 and the ball chamber cover 32 form a sand storage area. During rotation, the transfer area formed by the filter screen 34 and the inner wall of the ball chamber cover 31 can store the filtered cat litter. When the ball chamber assembly 3 rotates in the opposite direction to reset, the cat litter in the transfer area flows back to the sand storage area, improving the utilization efficiency of cat litter. The ball chamber assembly 3 is provided with a ball chamber litter outlet 38, and the base assembly 1 is provided with a base litter outlet 9 in the middle. The base litter outlet 9 is correspondingly set with the ball chamber litter outlet 38.

[0081] like Figure 12-15The litter filling component 4 is fixedly installed on the top of the upper cover component 2. A litter balance detection sensor 410 is fixedly installed at the front end of the chamber formed by the upper cover component 2 and the base component 1. The litter balance sensor 410 uses a TOF sensor or a camera. When the litter balance sensor 410 is a TOF sensor, it is also used to measure the height of the litter accumulation inside the ball chamber component 3. When the litter storage reaches a set threshold, the device status data is updated and fed back to the user terminal through the main control system. When the litter balance detection sensor 410 is a camera inside the ball chamber of a dual-camera system, the camera captures images of the litter, and the remaining litter balance is determined by an algorithm, thereby controlling the drive stroke of the litter filling motor 47. The litter filling component 4 includes a litter filling chamber body 41, a litter filling chamber upper cover 42, a litter filling chamber lower cover 43, an opening button 44, a body fixing lock 46, a litter filling motor 47, a litter filling impeller 48, and a litter filling port 49. The top of the litter filling chamber body 41... The litter bin is equipped with a litter bin cover 42, and an opening button 44 is located on the front top of the litter bin cover 42. The litter bin cover 42 can be opened by pressing the opening button to add cat litter into the litter bin. The litter bin lower cover 43 is locked to the top of the litter bin body 41 by a main body fixing lock 46. A litter filling port 49 is opened at the center of the bottom of the litter bin lower cover 43. A rotatable litter filling impeller 48 is set inside the connection channel between the litter filling port 49 and the litter bin. The central shaft of the litter filling impeller 48 is connected to the output shaft of the litter filling motor 47, and the litter filling motor 47 is fixedly installed on the litter bin body 41. The litter filling impeller 48 is driven by the litter filling motor 47 to transport the cat litter in the litter bin to the ball chamber assembly 3. The litter filling amount of the litter filling assembly 4 is controlled by the number of rotations of the litter filling impeller 48 driven by the built-in litter filling motor 47. The difference in detection data before and after litter filling by the TOF sensor is compared with the set litter filling amount to determine whether litter filling is successful.

[0082] like Figure 16 and 17As shown, the waste collection chamber 5 is located at the bottom of the base assembly 1. The waste collection chamber 5 includes a waste collection chamber body 51, a waste collection chamber front plate 52, a front plate groove 53, a handle 54, a drawstring hook 55, a shelf 56, and a soft rubber plate 57. The waste collection chamber front plate 52 is fixedly installed at the front end of the waste collection chamber body 51. The waste collection chamber front plate 52 is perpendicular to the waste collection chamber body 51. The front plate groove 53 is opened in the middle of the front end of the waste collection chamber front plate 52. The handle 54 is installed in the front plate groove 53. The handle 54 is C-shaped. The two ends of the handle 54 are rotatably connected to the groove wall of the front plate groove 53. The drawstring hook 55 is fixedly installed in the middle of the rear end of the handle 54. The drawstring hook 55 is perpendicularly connected to the handle 54. The top center of the waste collection chamber front plate 52 has a notch corresponding to the drawstring hook 55. The groove edge of the front plate groove 53... The structure has an arc-shaped transition. A frame plate 56 is fixedly installed on both the left and right sides of the main body 51 of the stool collection chamber. The length of the frame plate 56 matches the length of the main body 51 of the stool collection chamber. The frame plate 56 and the main body 51 of the stool collection chamber are an integral structure.

The interior camera 102 is fixedly embedded in the rear end face of the mounting base 101, with its lens facing the inside of the litter box to accurately capture the cat's littering activities. The interior camera 102 is electrically connected to an interior camera indicator light 15. When the interior camera 102 is activated, the indicator light 15 illuminates; otherwise, it turns off, allowing the user to intuitively understand the operating status of the interior camera 102. The exterior camera... Camera 103 is fixedly embedded in the front end face of mounting base 101, with the lens facing the outside of the litter box. It can monitor the cat's approach and preparation to enter the litter box in real time. The external camera 103 is electrically connected to the external camera working indicator light 16. When the external camera 103 is working, the external camera working indicator light 16 is lit, making it easy for users to know its working status. The shooting angle range α of the internal camera 102 and the shooting angle range β of the external camera 103 are both less than 180 degrees. This angle range setting can effectively avoid unnecessary redundant areas in the shooting image, while ensuring complete coverage of the target monitoring area and improving the practicality of the monitoring image.
