The excrement storage box 13 needs corresponding excrement storage capacity and flavor control function. The litter capacity can be approximately calculated to be three times the volume of litter available for consumption. The user will usually empty the litter box 13 at the same time as adding/replacing the litter, but it cannot be excluded that the user forgets to empty the litter box 13. The device senses the case of the toilet in the toilet storage box 13 and stops and reminds the user. The full-box sensing system is high in reliability by adopting a mechanical mode.

Referring to fig. 15, in the standby state, a sensing plate 20 (which may be a flat plate/mesh plate) is hung on the top side in the feces storage box 13. When the cleaning operation is started and the sand box 11 is lowered, the sensing plate 20 is raised to the top. When the dumping operation is completed and the sand magazine 11 is raised to the standby position, the sensing plate 20 is suspended again. If the stack of the excrement ball exceeds the warning height, the flat plate cannot be hung in place laterally and is jacked up by the excrement ball, and a switch is triggered to send an operation instruction, stop automatic cleaning and send a cleaning prompt.

Preferably, a cleaning device is further disposed in the excrement storage box 13, and the cleaning device is used for cleaning, sterilizing and odor-controlling the excrement storage box 13.

The odor control of the excrement storage box 13 adopts a combined mode of photocatalyst and ultraviolet ray killing. After each cleaning operation, the ultraviolet light is started for a suitable time, and the photocatalyst accelerates the decomposition of organic molecules in the catalytic gas under the irradiation of the ultraviolet light to form water and carbon dioxide, thereby reducing odor. The ultraviolet radiation can also directly kill the microorganisms on the surface of the accumulated excrement mass to prevent the breeding of the small insects.

In practical application, the housing 10 of the feces storage box 13 includes a hollow structure, and an absorbent is disposed inside the hollow structure. The side wall of the excrement storage box 13 is provided with a hollow structure, so that air inside the box and outside the box can circulate, and water inside the box is discharged outside the box. The inner side of the hollow structure can be provided with an activated carbon filter to prevent larger microorganisms from entering the box.

In the embodiment of the application, one end of the top cover 19 of the excrement storage box 13, which is far away from the filter screen 12, is rotatably connected with the side wall of the excrement storage box 13.

Referring to fig. 13 and 14, when the grit storage box 11 closes the bellmouth 14, the edge of the grit storage box 11 and the upper edge of the bellmouth 14 form a cutting action, which is potentially dangerous for the kitty. By providing the socket 14, the upper edge (the top cover 19 of the waste bin 13) can be raised to eliminate this risk. Specifically, the housing (top cover 19 of the toilet stool 13) which is located on the top of the toilet stool 13 and forms the upper edge of the faucet 14 is connected to the other parts by a hinge structure. When the sand box 11 is lifted, the top cover 19 can be lifted by an object caught in the receiving port 14. After the object is removed, the top cover 19 loses support and falls to reform the upper edge of the socket 14.

Further, a fourth sensing device is further disposed in the housing 10, and the fourth sensing device is used for sensing the state of pet excrement, and when the state of pet excrement conforms to a preset state, the health prompt is started. The device provides important health functions: and (5) monitoring the excrement condition of the cat and reminding the user when the excrement appears.

Specifically, the fourth sensing device comprises a microwave humidity sensor, an image sensor and a data processing unit; the microwave humidity sensor is arranged at the position of the filter screen 12 close to the faucet 14 and is used for detecting the humidity of the pet excrement passing through the faucet 14; the image sensor is used for acquiring a first image of pet excrement after the pet leaves the sand storage box 11 and a second image of pet excrement filtered by the filter screen 12; the data processing unit is used for determining the pet excrement state according to the humidity of the pet excrement, the first image and the second image, and starting the health reminding when the pet excrement state accords with the preset state.

The microwave humidity sensor is positioned at one side of the filter screen 12 and close to the position of the faucet 14 of the excrement storage box 13. As the fecal mass passes through the bellmouth 14, the microwave humidity sensor senses the moisture/water content of the fecal mass. If the screen surface of the filter screen 12 is made of metal, the whole screen surface can be used as a probe of a humidity sensor, and the sensing can be started when the filter screen 12 filters out the excrement. The camera of the image sensor is positioned at the rear top of the equipment, and can shoot images of the toilet at two time points when the cat leaves and the toilet is filtered by the filter screen 12;

the shape of the urine ball is regular and the shape of the normal stool ball is regular, so that the humidity is low. A more loose stool bolus may be regular in shape, but with higher humidity. The shape of the extremely thin and loose stool is irregular, and the humidity is very high. The data processing unit judges the two latter types of loose feces and reminds the user.

The data processing unit carries out image recognition on the image of the excrement cluster shot when the cat leaves, and the irregular excrement cluster is judged to be loose excrement; regular stool ball counts the total volume (area) of the stool ball. The device senses the humidity/moisture content of the excrement when the excrement is poured, combines the two data for evaluation, judges the excrement with the humidity exceeding the alarm value as loose excrement and starts reminding.

The pet health monitoring system can interact with the operation terminal and the server, and the user can remotely monitor and manage the pet health environment, so that convenience and controllability are brought to the user.
