Description

Technical Field

[0001] This invention belongs to the field of smart home appliance technology, specifically relating to a cat litter box and an assessment method for detecting the health of pet cats. Background Technology

[0002] As pet ownership becomes increasingly popular, pets' health is receiving more and more attention from owners. Accurate and timely monitoring of pets' health is crucial for disease prevention and improving their quality of life.

[0003] Generally, in households with pets, monitoring a pet's health relies primarily on the owner's daily observation. For example, owners might observe their pet's excrement to make a preliminary judgment about its health. However, because most owners are at work during the day, they cannot immediately observe the form of their pet's excrement when it urinates in the litter box. The moisture and odor of the excrement not only dissipate over time, but its form is also easily altered by other pets entering the litter box later, ultimately affecting the owner's ability to make a preliminary assessment of their pet's condition based on the excrement's appearance.

[0004] The obvious solution is to install a camera inside the litter box so that the owner can see the pet's excrement immediately after it has finished relieving itself. However, in reality, pets instinctively cover their excrement in the litter box, making it difficult for the camera to capture the shape of the excrement within the litter. Furthermore, even if the excrement isn't buried, its color blends seamlessly with the litter background, making it hard to discern its shape. Ultimately, this hinders the owner's ability to make an initial assessment of their pet's condition based on the appearance of their excrement. Summary of the Invention

[0005] To address the problem that pet owners cannot clearly observe the form of their pet's excrement immediately after defecation, thus hindering their ability to make preliminary judgments about their pet's condition by observing the excrement's appearance, this invention provides a litter box and an assessment method for detecting the health of pet cats.

[0006] The objective of this invention can be achieved through the following technical solutions: A cat litter box, characterized in that it includes a litter seat, a hollow litter hopper, a sieve, and a camera. The litter hopper is rotatably mounted on the litter seat. Along the clockwise rotation direction of the litter hopper, the litter hopper has a discharge port, a sieve port, and a collection port. The discharge port is filled with cat litter. The sieve port is disposed on the sieve port for sieving cat litter and excrement. The collection port is used to collect excrement. The litter box also has a sieving trough and a collection trough. The axis of the sieving trough is set along the clockwise rotation direction of the litter box, and the front end of the sieving trough is connected to the sieving port. The axis of the collection trough is set along the counterclockwise rotation direction of the litter box, and the front end of the collection trough is connected to the collection port. The camera is set on the litter box and is used to capture the bottom of the litter box.

[0007] As a preferred embodiment of the present invention, it further includes a judgment camera, which is disposed on the cat litter seat and is used to capture the situation at the cat litter box outlet.

[0008] As a preferred embodiment of the present invention, both the screening trough and the receiving trough are arc-shaped structures.

[0009] As a preferred embodiment of the present invention, it further includes a hollow storage box, wherein the litter box has a placement slot that communicates with the storage slot, and the storage box is detachably disposed in the placement slot for storing excrement.

[0010] As a preferred embodiment of the present invention, the internal space of the storage box includes a first space, and the cat litter box is provided with a connecting slot, which is connected to the storage slot and the placement slot respectively; it also includes a sieving component, which includes a sieving disc and a vibration module. The sieving disc is disposed in the connecting slot, and the vibration module is disposed on the sieving disc. The sieving disc is provided with a strip-shaped slot, which is connected to the first space.

[0011] As a preferred embodiment of the present invention, the internal space of the storage box further includes a second space, the sieving assembly further includes a pushing unit, the pushing unit includes a pushing cylinder and a pushing block, the cat litter box is also provided with a pushing slot, the pushing cylinder is disposed in the pushing slot, the pushing block is connected to the output end of the pushing cylinder, and the bottom surface of the pushing block is on the same horizontal plane as the surface of the sieving disc; The litter box also has a storage slot opposite to the push slot. The storage slot is connected to the second space and the connecting slot, respectively. The bottom surface of the storage slot is flush with the surface of the sieving plate.

[0012] As a preferred embodiment of the present invention, the pushing unit further includes a closing cylinder and a closing block. The closing cylinder is disposed in the storage slot, and the output end of the closing cylinder is connected to the closing block. The closing block can lock or release its sealing relationship with the connection between the storage slot and the connecting slot.

[0013] As a preferred embodiment of the present invention, a plurality of strip-shaped slots are provided, and the plurality of strip-shaped slots are equally spaced along the diameter direction of the screening disc. The arrangement direction of the plurality of strip-shaped slots is perpendicular to the projection direction of the swing direction of the receiving groove onto the surface of the screening disc when it is reset.

[0014] As a preferred embodiment of the present invention, along the sliding direction of the excrement, the strip-shaped groove includes, in sequence, a vertical groove, a transition groove, and an inclined groove connected to each other. The vertical groove is vertically disposed within the screening disc, the inclined groove is inclinedly disposed within the screening disc, and the two ends of the transition groove are tangent to the vertical groove and the inclined groove, respectively.

[0015] A litter box-based assessment method for monitoring the health of pet cats includes the following steps: S1: After the pet finishes defecating in the litter box, the litter box starts working, controlling the excrement to move to the collection opening, and controlling the camera to take pictures of the excrement; S2: Next, the excrement is controlled onto the screening plate, and the vibration module starts to work, causing the excreted feces in the excrement to fall into the first space through the strip-shaped slot holes; S3: After all the excrement on the screening plate has fallen into the first space through the strip-shaped slot, the push cylinder is controlled to push the excrement on the screening plate through the storage slot into the second space, thus completing the classification and collection of excrement. S4: By observing the amount and shape of feces excreted in the first space and the amount and shape of urine excreted in the second space, it is possible to make a preliminary judgment on the pet's condition by observing the shape of the pet's excrement.

[0016] The beneficial effects of this invention are as follows: This litter box design features a cylindrical structure. After the cat finishes relieving itself in the litter box, some litter in the vent has already adhered to the excrement. The litter box then rotates, moving both the litter and excrement from the vent to the sieving inlet. In this design, a sieving screen is installed at the sieving inlet, and the sieving trough is connected to the sieving inlet. Due to the sieving screen, the excrement is trapped at the sieving inlet, while the litter passes through the screen and enters the sieving trough. The litter box then continues to rotate, moving the excrement from the sieving inlet to the collection inlet, while the litter... The litter box moves from the front end of the sieving trough to the back end. Since the collection trough is connected to the collection opening, the excrement will fall into the front end of the collection trough due to gravity after it moves to the collection opening. When the litter box starts to rotate counterclockwise to reset, the excrement that was originally located at the front end of the collection trough will move to the back end of the collection trough, thus collecting and processing the excrement. At the same time, the litter that was originally located at the back end of the sieving trough will move to the front end of the sieving trough. As the litter box continues to rotate and reset, the litter that was located at the front end of the sieving trough will pass through the sieving screen and move back to the excrement opening. Before the litter box rotates and resets, this solution includes a camera mounted on the litter seat to capture images of the bottom of the litter box. It's important to emphasize that the rotation described in this solution refers to the litter box rotating relative to its own weight on the litter seat. The camera captures the bottom of the litter box, allowing the camera to record the movement of waste to the collection opening. Without litter interference, the camera can clearly capture the size and shape of the pet's waste immediately. This solves the problem of owners being able to obtain information about their pet's waste even when they are not home, and avoids the litter's presence affecting the owner's observation of the waste's shape, ultimately hindering the owner's initial assessment of the pet's condition based on the waste's appearance.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Please see Figures 1-8This embodiment provides a cat litter box, including a litter seat 1, a hollow litter box 2, a sieve 4, and a camera 5. The litter box 2 is rotatably mounted on the litter seat 1. Along the clockwise rotation direction of the litter box 2, the litter box 2 has a discharge port 201, a sieve port 202, and a collection port 203. The discharge port 201 is filled with cat litter. The sieve 4 is set on the sieve port 202 for sieving cat litter and excrement. The collection port 203 is used to collect excrement. The litter box 2 also has a sieve groove 204 and a collection groove 205. The axis of the sieve groove 204 is... The sieving trough 204 is positioned along the clockwise rotation direction of the litter box 2, with its front end connected to the sieving opening 202. The collection trough 205 is positioned along the counterclockwise rotation direction of the litter box 2, with its front end connected to the collection opening 203. A camera 5 is mounted on the litter seat 1 to capture images of the bottom of the litter box 2. It should be noted that the litter box 2 in this design has a cylindrical structure. After the cat has finished defecating in the litter box, some litter in the excretion opening 201 has already adhered to the excrement. At this point, the litter box 2 begins to rotate. The cat litter and excrement located at the excretion outlet 201 move together to the sieving outlet 202. In this design, a sieving screen 4 is installed at the sieving outlet 202, and the sieving trough 204 is connected to the sieving outlet 202. Due to the action of the sieving screen 4, the excrement is blocked at the sieving outlet 202, while the cat litter passes through the sieving screen 4 and enters the sieving trough 204. Then, the cat litter box 2 continues to rotate, and the excrement moves from the sieving outlet 202 to the collection outlet 203, while the cat litter moves from the front end of the sieving trough 204 to the end of the sieving trough 204. Because the collection trough 205 and the collection outlet 203 are connected... Because of the connection between 03 and 204, the excrement will fall into the front end of the collection trough 205 due to gravity after it moves to the position of the collection opening 203. When the litter box 2 starts to rotate counterclockwise to reset, the excrement that was originally located at the front end of the collection trough 205 will move to the end of the collection trough 205 to achieve the collection and processing of the excrement. At the same time, the cat litter that was originally located at the end of the sieving trough 204 will move to the front end of the sieving trough 204. As the litter box 2 continues to rotate to reset, the cat litter located at the front end of the sieving trough 204 will pass through the sieving screen 4 and move back to the position of the excrement opening 201.Before the litter box 2 rotates and resets, this solution also includes a camera 5 mounted on the litter seat 1 to capture images of the bottom of the litter box 2. It's important to emphasize that the rotation of the litter box 2 described in this solution actually refers to its rotation relative to the litter seat 1. The camera 5 captures images of the bottom of the litter box 2. Therefore, when the litter box 2 rotates, the camera 5 can capture images of the excrement moving to the collection opening 203. At this point, without the interference of litter, the camera 5 can clearly capture the size and shape of the pet's excrement immediately. This not only solves the problem of owners being able to obtain information about their pet's excrement even when they are not at home, but also avoids the litter's presence affecting the owner's observation of the excrement's shape, ultimately preventing the owner from making a preliminary judgment about the pet's condition based on the appearance of the excrement. It should be noted that both the sieving trough 204 and the collection trough 205 in this design are arc-shaped structures. When the litter box 2 rotates clockwise, the litter in the sieving trough 204 can only move from the front end to the back end of the sieving trough 204; and the excrement in the sieving trough 204 can only move to the front end of the collection trough 205. When the litter box 2 rotates counterclockwise, the litter in the sieving trough 204 can only move from the back end to the front end of the sieving trough 204; and the excrement in the collection trough 205 can only move from the front end to the back end of the collection trough 205.

[0022] It is worth noting that before the litter box 2 in this solution rotates, it is necessary to ensure that the pet cat has already stepped out of the litter box. However, the camera 5 can only capture the bottom of the litter box 2 and cannot capture the entire interior of the litter box 2. Therefore, it is impossible to determine whether the pet cat has stepped out of the litter box based on the information captured by the camera 5. Based on this, this solution also includes a judgment camera 6, which is set on the litter seat 1 and is used to capture the situation at the exit of the litter box 2. With the judgment camera 6, the pet cat can be captured when entering or leaving the litter box 2. Therefore, the judgment camera 6 can be used to determine whether the pet cat is inside the litter box 2.

[0023] This solution also includes a structure for storing excrement. Specifically, it includes a hollow storage box 7. The litter box 1 has a placement slot 206 that communicates with the end of the storage slot 205. The storage box 7 is detachably installed in the placement slot 206 for storing excrement. When the litter box 2 rotates to its reset position, the excrement at the front end of the storage slot 205 will move to the end of the storage slot 205, and finally, the excrement at the end of the storage slot 205 will fall into the storage box 7 due to gravity.

[0024] In the above embodiment, this solution separates and photographs pet excrement from the litter box, allowing the owner to observe the shape of the excrement immediately after it is excreted. However, pet excrement typically includes feces and urine. Because feces and urine are mixed together, the owner cannot know the exact proportion of feces and urine in the excrement. Accurately determining the feces-urine ratio in excrement is crucial for monitoring pet health—a low urine ratio often indicates dehydration or urinary tract obstruction; an abnormally high feces ratio with a hard, dry consistency reflects constipation and insufficient water intake; a sudden drop in feces ratio with a soft consistency suggests diarrhea or digestive problems. Only by clearly distinguishing the feces-urine ratio in excrement can the pet's health be further monitored. Therefore, this solution also needs to differentiate the feces-urine ratio in excrement.

[0025] Specifically, to enable the device to collect excrement, the internal space of the collection box 7 in this design includes a first space, and the litter box 2 is also provided with a connecting slot 207, which is interconnected with the collection slot 205 and the placement slot 206 respectively; it also includes a screening component 8, which includes a screening disc 801 and a vibration module 802. The screening disc 801 is disposed in the connecting slot 207, and the vibration module 802 is disposed on the screening disc 801. The screening disc 801 is provided with a plurality of strip-shaped slots 8011, which are evenly spaced along the diameter of the screening disc 801. The arrangement direction of several strip-shaped slots 8011 is perpendicular to the projection direction of the swing direction of the collection tank 205 when it is reset onto the surface of the screening disc 801; the strip-shaped slots 8011 are interconnected with the first space; with this arrangement, when the excrement moves to the end of the collection tank 205, due to gravity, the excrement will fall onto the screening disc 801, and then the vibration module 802 will start working, causing the excrement on the screening disc 801 to vibrate, so that the excreted feces in the excrement fall into the first space through its adjacent strip-shaped slots 8011, thus completing the collection of excreted feces. It is important to note that feces adhere to cat litter and clump into strips, while urine adheres to cat litter and clumps into irregular lumps. In practice, the volume of clumped urine is much larger than that of clumped feces. Furthermore, because the clumped urine falls onto the sieving disc 801, due to gravity, it always falls onto the disc 801 with the end face having the largest contact area. Therefore, clumped urine cannot fall into the first space through the strip-shaped slot 8011, while clumped feces can fall into the first space through the strip-shaped slot 8011, thus completing the centralized collection of feces.

[0026] Furthermore, to achieve the collection of excreted urine, the internal space of the collection box 7 in this solution also includes a second space, and the screening component 8 also includes a pushing unit 9. The pushing unit 9 includes a pushing cylinder 901 and a pushing block 902. The litter box 2 also has a pushing slot, and the pushing cylinder 901 is set in the pushing slot. The pushing block 902 is connected to the output end of the pushing cylinder 901, and the bottom surface of the pushing block 902 is on the same horizontal plane as the surface of the screening disc 801. The litter box 2 also has a storage slot opposite to the pushing slot. The storage slot is connected to the second space and the connecting slot 207 respectively, and the bottom surface of the storage slot is flush with the surface of the screening disc 801. After the excreted feces are collected and processed, only excreted urine remains on the screening disc 801. At this time, the driving pushing cylinder 901 starts to work, so that the pushing block 902 moves and pushes all the excreted urine on the screening disc 801 into the storage slot, thereby achieving the collection of excreted urine.

[0027] Furthermore, it should be noted that, as mentioned in the above embodiments, the volume of excreted urine is greater than the volume of excreted feces. Therefore, in this solution, the cross-sectional area of ​​the storage slot is also greater than the cross-sectional area of ​​the strip slot 8011. This presents a problem where excreted feces may fall into the second space through the storage slot during the vibration of the screening disc 801. To avoid this problem, the driving unit 9 in this solution also includes a closing cylinder 903 and a closing block 904. The closing cylinder 903 is disposed in the storage slot, and its output end is connected to the closing block 904. The closing block 904 can lock or release its sealing relationship with the storage slot. By providing the closing cylinder 903, before the excreted feces on the screening disc 801 are completely collected, the closing cylinder 903 controls the closing block 904 to move, thereby sealing the connection between the storage slot and the connecting slot 207 and preventing excreted feces from falling into the second space through the storage slot.

[0028] Furthermore, it is worth noting that in the actual application of this solution, the excrement that moves into the collection trough 205 falls into the end of the collection trough 205 due to gravity during the resetting of the litter box 2. That is, during the resetting of the litter box 2, the excrement that falls into the end of the collection trough 205 will directly fall onto the sieving disc 801. Based on this situation, in order to accelerate the efficiency of the sieving disc 801 in distinguishing and collecting excreted feces and excreted urine, the sieving disc 801 of this solution has several strip-shaped slots 8011. The strip-shaped slots 8011 are evenly spaced along the diameter direction of the sieving disc 801. The arrangement direction of the strip-shaped slots 8011 is perpendicular to the projection direction of the swing direction of the collection trough 205 when resetting onto the surface of the sieving disc 801. Through this arrangement, the excrement is evenly distributed in the area of ​​the strip-shaped slots 8011, thereby accelerating the collection speed of excreted feces.

[0029] The cross-sectional shape of the strip-shaped slot 8011 in this design is an arc-shaped structure. Specifically, along the sliding direction of excreted feces, the strip-shaped slot 8011 sequentially includes interconnected vertical slots 803, transition slots 804, and inclined slots 805. The vertical slots 803 are vertically arranged within the screening disc 801, and the inclined slots 805 are inclined within the screening disc 801. The two ends of the transition slots 804 are tangent to the vertical slots 803 and the inclined slots 805, respectively. With this arrangement, when excrement falls from the end of the collection trough 205, there are blocky... The excreted urine falls vertically due to gravity. Although the volume of the lumpy excreted urine is larger than that of the strip-shaped excreted feces, it does not mean that the thickness of the lumpy excreted urine will be greater than the maximum cross-sectional diameter of the strip-shaped excreted feces, nor will it necessarily be greater than the width of the slot opening of the strip-shaped slot 8011. Therefore, during the process of excrement falling, the lumpy excreted urine will fall directly into the strip-shaped slot 8011 in a vertical state. The aforementioned transition slot 804 can prevent the lumpy excreted urine from falling directly into the first space through the vertical slot 803.

[0030] The above embodiment describes a problem where urine excretion causes blockage of the corresponding strip-shaped slots 8011. To solve this potential problem, this solution further includes several adjustment units 10, each corresponding to a number of strip-shaped slots 8011. Each adjustment unit 10 is disposed within a corresponding strip-shaped slot 8011. In this solution, the screening disc 801 also has several vertical adjustment slots, each corresponding to a number of strip-shaped slots 8011. Each adjustment slot is vertically disposed within a corresponding transition slot 804, and the central axis of the adjustment slot coincides with the central axis of the vertical slot 803. The adjustment unit 10 includes an adjustment cylinder 1001 and an adjustment... The segment 1002 and the regulating cylinder 1001 are coaxially arranged in the regulating slot. The regulating block 1002 is connected to the output end of the regulating cylinder 1001. Under normal conditions, the regulating block 1002 is hidden in the regulating slot. When the excreted urine falls into the corresponding vertical slot 803, the regulating cylinder 1001 starts to work, controlling the regulating block 1002 to abut against the excreted urine, and controlling the top surface height of the excreted urine to be level with the surface height of the screening disc 801, or controlling the top surface height of the excreted urine to be higher than the surface height of the screening disc 801. Through this setting, it is firstly to prevent the excreted urine from falling into the strip slot 8011, and the remaining excreted feces will fall into the strip slot 8011 due to vibration.

[0031] Furthermore, the adjustment unit 10 of this scheme also includes a moving cylinder 1003 and a moving block 1004. The screening disc 801 is also provided with a number of moving slots, which correspond to and match a number of strip slots 8011. Each moving slot is set in the side wall of the corresponding vertical slot 803. The two ends of the moving slot are respectively connected to the vertical slot 803 and the second space. The moving cylinder 1003 is set in the other side wall of the vertical slot 803 relative to the moving slot. The moving block 1004 is connected to the output end of the moving cylinder 1003. By providing the moving cylinder 1003, when the moving cylinder 1003 starts to work, it will drive the moving block 1004 to press against the excreted urine located in the vertical slot 803, pushing the excreted urine to move into the moving slot, and finally solving the problem of excreted urine blocking the strip slot 8011. It is important to note that both the moving cylinder 1003 and the moving block 1004 are concealed within the side wall of the vertical slot 803; and the moving cylinder 1003 is located at the top of the vertical slot 803.

[0032] It is important to note that in this design, it is impossible to move the urine clogged in the vertical slot 803 out of the strip slot 8011 by controlling the regulating cylinder 1001. This is because the urine has already clogged the strip slot 8011, so there is still some urine and feces on the screening disc 801. If the regulating cylinder 1001 is directly controlled to move the urine clogged in the vertical slot 803 out of the strip slot 8011, it will cause the urine to flow directly out of the slot. When urine or feces are placed on top of other excreted urine or feces, two situations arise: First, due to the superposition of multiple excreted urine samples, the height of the push slot opening becomes lower than the height of the superimposed urine, preventing the superimposed urine from smoothly entering the push slot. Second, if the excreted urine is superimposed on excreted feces, the feces will not be able to move due to the vibration of the screening disc 801, thus preventing them from smoothly entering the strip slot 8011 for classified collection. In summary, in this solution, it is impossible to move the urine blocked in the vertical slot 803 out of the strip slot 8011 by controlling the regulating cylinder 1001.

[0033] Furthermore, to prevent excrement from falling into the second space through the movable slot, the adjustment unit 10 of this solution also includes a sealing door 1005 with a reset function. One end of the sealing door 1005 is hinged to one end of the movable slot. Under normal conditions, the sealing door 1005 and the movable slot are in a sealed fit. When the movable cylinder 1003 pushes the excreted urine against the sealing door 1005, the sealing door 1005 will release its sealed fit with the movable slot, allowing the excreted urine to fall smoothly into the second space, and the sealing door 1005 will then re-seal its fit with the movable slot.

[0034] Furthermore, it is worth noting that in this solution, in order to facilitate the determination of whether the excreted urine is blocked in the vertical slot 803, and also to facilitate the subsequent determination of whether the regulating cylinder 1001 controls the top surface height of the blocked excreted urine to be equal to or higher than the surface height of the sieve plate 801, the regulating unit 10 of this solution also includes an regulating camera 1006. The regulating camera 1006 is set on the top of the side wall inside the vertical slot 803 for observing the situation inside the vertical slot 803.

[0035] In addition, the storage box 7 in this solution is equipped with two visual modules, which correspond to the first space and the second space respectively. Each visual module is used to photograph the excrement in the corresponding space, which is convenient for subsequent assessment of the pet's health.

[0036] A litter box-based assessment method for monitoring the health of pet cats includes the following steps: S1: After the pet finishes its defecation in the litter box 2, the litter box 2 starts to work, controlling the excrement to move to the collection opening 203, and controlling the camera 5 to take pictures of the excrement. S2: Next, the excrement is controlled onto the screening plate 801, and the vibration module 802 starts to work, causing the excreted feces in the excrement to fall into the first space through the strip slot 8011. S3: After all the excrement on the screening disc 801 has fallen into the first space through the strip slot 8011, the push cylinder 901 is controlled to push the excrement on the screening disc 801 through the storage slot into the second space, thus completing the classification and collection of excrement. S4: By observing the amount and form of feces excreted in the first space and the amount and form of urine excreted in the second space, the pet's condition can be preliminarily judged by observing the form of the pet's excrement.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
