Description
Technical Field
[0001] The present invention relates to the technical field of pet monitoring, and particularly to a method for obtaining pet health information of a pet toilet. Background Art
[0002] With the development of society, there are now some pet toilets with automatic feces cleaning functions on the market. For example, in the Chinese patent application for invention with the publication number CN118749437A and the name "An Intelligent Pet Toilet", these pet toilets collect the fecal sand blocks in the sand container through a feces cleaning device, crush the fecal sand blocks and mix them with water to form a mortar, and finally discharge them into the sewer, thus avoiding the accumulation of feces in the sand container. Users do not need to manually process the feces of pets, making the pet toilet more intelligent and hygienic. However, while these pet toilets are intelligent, they also bring new technical problems. It is difficult for users to observe and monitor the defecation status of pets to evaluate the health status of pets, making it difficult to detect the health problems of pets in a timely manner.
[0003] In addition, the Chinese patent application for invention with the publication number CN118383290A and the name "Pet Health Information Monitoring System and Method Based on Intelligent Pet Toilet Equipment" discloses a pet health information monitoring system and method. In the technical solution of this document, 2 sets of weight sensing units are used to monitor the cat litter container unit and the feces collection bin unit respectively. However, for automatic flushing and discharging type pet toilets, such as the pet toilet disclosed in the above-mentioned CN118749437A document, since the feces cleaning device used in it will add water to crush and discharge the fecal clumps, if a weight sensor is directly installed at the bottom of this device, it is required that there is no hard connection between this device and the chassis, which will make the noise of this device increase during operation and affect the use experience. Therefore, this monitoring system and method are not applicable. For this reason, a method for obtaining pet health information applicable to this type of pet toilet is needed. Summary of the Invention
[0004] The purpose of the present invention is to provide a method for obtaining pet health information of a pet toilet, which enables users to conveniently monitor the defecation status of pets to monitor the health status of pets, so that the health problems of pets can be detected in a timely manner, and this method is applicable to automatic flushing and discharging type pet toilets.
[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: A method for obtaining pet health information of a pet toilet. In particular, there is only one set of weight sensors for monitoring the weight on the pet litter tray of the pet toilet. When no pet stands on the pet litter tray, the main control program records the static weight measured on the pet litter tray at this time as weight A. When the main control program detects a weight increase event, the main control program records the weight measured on the pet litter tray at this time as weight D. When it is determined that this weight increase event is not due to the pet defecating, the main control program does not use weight D as the calculation data for pet health information and does not perform the sand cleaning operation. When it is determined that this weight increase event is due to the pet defecating, the main control program uses weight D as the calculation data for pet health information. When it is determined that this weight increase event is due to the pet defecating, after the main control program determines that the pet has left the pet litter tray, the main control program records the weight measured on the pet litter tray at this time as weight B, and then performs the sand cleaning operation. After the sand cleaning operation is completed, the main control program records the weight on the pet litter tray at this time as weight C. When obtaining pet health information, obtain the weight W of this pet = weight D - weight B, obtain the weight P of this defecation = weight B - weight A, and obtain the weight S of the reduction of the pet litter this time = weight A - weight C. If the weight P of this time is greater than the weight S of this time, obtain the type of this defecation as feces. If the weight P of this time is less than or equal to the weight S of this time, obtain the type of this defecation as urine.
[0006] Through the above method, it is possible to obtain the weight W of this pet, the weight P of defecation, and the type of defecation under the condition of only setting one set of weight sensors for monitoring the weight on the pet litter tray, providing data support for subsequent pet health assessment by recording and statistics for users. And because the said weight sensors are not specifically for monitoring the weight on the feces treatment device or the feces collection bin, but are set to monitor the weight on the pet litter tray, so the weight sensors can be set directly under the pet litter tray to monitor the weight on the pet litter tray, or set near the bottom of the pet litter tray, or even set under the chassis of the pet toilet to indirectly monitor the weight on the pet litter tray (at this time, it is required that the pet toilet is of the automatic flushing and discharging type, or the collection type where the weight of the feces clump will not be added to the weight sensor after the sand cleaning operation is performed), which greatly reduces the mechanical structure design threshold of such automatic pet toilets. It should be noted that the main data obtained by the method of the present invention is essentially the difference in weight. Therefore, even when the weight sensor is set under the chassis of the pet toilet, even if the weight sensor monitors the weight of all components including the chassis shell and those inside and on the chassis such as the pet litter tray and the feces treatment device, as long as the weight of the feces clump will not be added to the weight sensor after the sand cleaning operation is performed, it will not affect the calculated result.
[0007] It should be noted that the provision of one set of weight sensors does not mean provision of only one weight sensor, but means provision of one or more weight sensors. In the case of more than one weight sensor, the weight value is generally the sum of the respective measured values of these weight sensors.
[0008] The main control program determines that no pet is currently standing on the pet litter tray under the following conditions: the pet toilet has just been powered on and has completed self-test; or the litter cleaning operation has just been completed.
[0009] The main control program determines whether the weight increase event is a pet's defecation by the following conditions: if a weight reduction event is found after the timing duration t2 ends and before the timing duration t3 ends, and the weight is reduced to the range of weight A + preset weight X, the weight increase event is determined to be a pet's defecation, and the pet is determined to have left the pet litter tray, otherwise the weight increase event is not a pet's defecation. The value range of the timing duration t2 is the maximum time that the pet stays on the pet litter tray without the intention of defecation, and its value range is generally 5 seconds to 30 seconds, and the value range of the timing duration t3 is the maximum time that the pet stands on the pet litter tray until the defecation is completed and leaves, and its value range is generally 1 minute to 5 minutes. It should be noted that if no weight reduction event occurs after the timing duration t3 ends from the discovery of the weight increase event, the main control program still determines that the weight increase event is not a pet's defecation, but may just be an artificial sand addition operation. In addition, even if the weight reduction event occurs after the timing duration t2 ends and before the timing duration t3 ends, but the weight reduction to the range of weight A + preset weight X is not met, it is possible that part of the pet litter is manually removed, that is, the sand reduction operation; if the weight reduction event occurs during the timing duration t2, and the weight reduction to the range of weight A + preset weight X is met, it is possible that the pet is just curious and not standing on the pet litter tray with the intention of defecation; if the weight reduction event occurs during the timing duration t2, and the weight reduction to the range of weight A + preset weight X is not met, it is possible that only the manual sand reduction operation is performed. Therefore, such conditional settings can effectively reduce misjudgments and improve the accuracy of sand cleaning operations. It should be noted that the preset weight X is set based on the assumption that the weight of a pet's single defecation will not exceed this weight. When facing pets of different breeds and ages, this setting can be set once when the pet toilet product leaves the factory, or a user operation interface is provided for the user to set it by himself. For common pet cats, the preset weight X is generally set in the range of 50g to 500g.
[0010] The determination condition for the main control program to determine whether the weight increase event is due to the pet defecating can also be: If after detecting the weight increase event, it is recognized through photographing that the pet has defecated and the pet has left the litter box, then it is determined that the weight increase event is due to the pet defecating, and it is determined that the pet has left the litter box; otherwise, it is determined that the weight increase event is not due to the pet defecating.
[0011] In addition, the described sand cleaning operation can be a collecting type sand cleaning operation or an automatic discharging type sand cleaning operation. The so-called collecting type sand cleaning operation means that the fecal mass is transferred to a feces storage bin for storage. The so-called automatic discharging type sand cleaning operation means that the fecal mass is transferred to an automatic flushing and discharging device and then discharged from the pet toilet immediately.
[0012] The technical solution of the present invention can be used to obtain the pet health information of a collecting type or automatic discharging type pet toilet by only using 1 set of weight sensors, which simplifies the structural design and manufacturing of the pet toilet product, has a low misjudgment rate, and can achieve the desired effect.

[0015] In order to have a clearer understanding of the technical solution, purpose and effect of the present invention, the detailed embodiment of the present invention will now be described in detail with reference to the drawings.
[0016] The pet health information acquisition method of this embodiment is based on an automatic flushing and discharging type pet toilet. As Figure 1As shown in the figure, the pet toilet includes a chassis 1 and a roller 2 installed on the chassis 1. Inside the roller 2, there is a filter sand net 21, a sand storage bin 22, and a pet sand tray 23. Between the chassis 1 and the roller 2, there are a roller seat and rollers (the roller seat and rollers are not shown), and the rollers enable the roller 2 to be more easily driven by a roller drive device (the roller drive device is not shown) to rotate. When performing the sand cleaning operation after the pet defecates, the roller 2 will rotate a certain angle. At this time, the pet sand that has not been contaminated by feces can pass through the filter sand net 21 and enter the sand storage bin 22, while the pet sand contaminated by feces will adhere to the feces to form a fecal mass. Because the fecal mass is relatively large in volume and cannot pass through the filter sand net 21 and enter the sand storage bin 22, with the continuous rotation of the roller 2, the fecal mass will pass over the filter sand net 21 and fall into a preset opening on the roller 2. This opening is the discharge port 24 of the roller 2. When the roller 2 rotates into place, the discharge port 24 will be directly opposite the automatic flushing and discharging device 11 located below the roller 2 to allow the fecal mass to fall into the automatic flushing and discharging device 11. The automatic flushing and discharging device 11 includes a stirring knife, a water injection device, and a sewage impeller. When performing the sand cleaning operation, the automatic flushing and discharging device 11 can crush the fecal mass and discharge it through a pipeline away from the pet toilet.
[0017] One weight sensor 12 is respectively arranged under the four corners of the chassis 1 of the pet toilet, so a total of 4 are arranged. The sum of the weights measured by these 4 weight sensors 12 at the same moment is equal to the overall weight G of the pet toilet. They constitute a set of weight sensors for monitoring the weight on the pet toilet. Since the weight of the fecal mass will not be added to the weight sensor 12 after the subsequent sand cleaning operation, in the absence of external sudden interference, the 4 weight sensors 12 are equivalent to monitoring the change in the weight on the pet sand tray 23. Therefore, these 4 weight sensors 12 can be regarded as weight sensors for monitoring the weight on the pet sand tray 23.
[0018] After the pet toilet is just powered on and the self-check is completed, or after the sand cleaning operation is just completed, at this time the main control program determines that there is no pet standing on the pet sand tray at present, and the main control program records the static weight on the pet sand tray measured at this time as weight A. At this time:
[0019] Weight A = the overall weight G of the pet toilet + the weight N of the original pet sand.
[0020] When the main control program detects a weight increase event, the main control program records the weight measured on the pet litter box at this time as weight D, and starts timing for timing duration t2 and timing duration t3. Among them, the timing duration t2 is set to 15 seconds, and the timing duration t3 is set to 3 minutes. If a weight decrease event is detected after the end of timing duration t2 and before the end of timing duration t3, and the weight reduced by the weight decrease event is within the range of weight A + preset weight X, in this embodiment, the preset weight X = 150g. At this time, it is determined that the weight increase event is that the pet has defecated, and it is determined that the pet has left the pet litter box. Under this determination, the composition of the previously recorded weight D is:
[0021] Weight D = the overall weight G of the pet toilet + the weight N of the original pet litter + the weight W of the pet + the weight V of the pet about to defecate.
[0022] After determining that the pet has left the pet litter box, the main control program records the weight measured on the pet litter box at this time as weight B. At this time:
[0023] Weight B = the overall weight G of the pet toilet + the weight N of the original pet litter + the weight P of this defecation.
[0024] After that, a sand cleaning operation is performed. The sand cleaning operation in this embodiment belongs to an automatic discharge type sand cleaning operation. Therefore, the weight of the fecal mass will not be added to the weight sensor after the sand cleaning operation. After the sand cleaning operation is completed, the main control program records the weight on the pet litter box at this time as weight C. At this time:
[0025] Weight C = the overall weight G of the pet toilet + the weight M of the current remaining pet litter.
[0026] As can be seen from the above, since the weight V of the pet about to defecate = the weight P of this defecation, it can be obtained that the weight W of this pet = weight D - weight B; the weight P of this defecation = weight B - weight A; the weight S reduced by this pet litter = weight A - weight C = the weight N of the original pet litter - the weight M of the current remaining pet litter. Using the phenomenon that the weight of the pet litter taken away by the fecal mass is lighter when the feces have less water and heavier when the urine has more water, if the weight P of this time is greater than the weight S of this time, it can be determined that the type of this defecation is feces; if the weight P of this time is less than or equal to the weight S of this time, it can be determined that the type of this defecation is urine at this time. When obtaining pet health information, the above data and determination conclusions can be obtained.
[0027] To reduce misjudgment, when the main control program detects an event of weight increase, although the main control program will record the weight measured on the pet litter box at this time as weight D, if no weight reduction event occurs after the end of the timing duration t3, or if a weight reduction event occurs during the timing duration t3 but the degree of weight reduction does not reach the range of being reduced to weight A + preset weight X, or if the degree of weight reduction of the weight reduction event reaches the range of being reduced to weight A + preset weight X but such a weight reduction event only occurs during the timing duration t2, then none of these three situations will determine that the pet has defecated. Subsequently, the main control program will not use weight D as the calculation data for pet health information and will not perform the sand cleaning operation.
[0028] Through the method of this embodiment, it is possible to obtain pet health information very simply by setting a weight sensor.
[0029] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes, combinations, and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
