Description

CROSS-REFERENCE TO RELATED APPLICATION The present disclosure claims priority to Chinese patent application No. 202411552693.5, filed with the Chinese Patent Office on Nov. 1, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the technical field of pet supplies, and in particular to a control method, device and system for a feces cleaning system. BACKGROUND ART With the development of society and the improvement of living standards, people's pursuit of quality of life is also constantly improving. In the field of pet care, pet cats, as important members of the family, are also valued for their quality of life. The optimization of modern living area planning and the improvement of pet care requirements have made the living environment and sanitary conditions of pet cats the focus of attention. However, the fast-paced lifestyle has made pet owners face challenges in pet sanitation management, especially in the cleaning and maintenance of cat toilets. Although the existing cat toilet technology has achieved automation to a certain extent, it can automatically perform the cleaning process and reduce the burden on pet owners. These technologies usually include functions such as automatic cleaning of feces and automatic replenishment of cat litter in order to achieve the effect of freeing hands. However, despite the progress made in automation, these technologies still have deficiencies in feces treatment and odor control. Specifically, before and after the cleaning process of cat toilets in the prior art, feces are often exposed to the air for a long time, resulting in the continuous emission of feces odor in the space where the cat litter box is located, causing the deterioration of environmental sanitation. This continuous odor emission not only affects the comfort of the living environment, but also may attract insects to enter and lay eggs, further exacerbating environmental pollution. In addition, the long-term presence of fecal odor may also have potential impacts on human health and the physical health of pet cats, especially in confined or poorly ventilated spaces. In summary, although the existing cat toilet technology has made some progress in automated cleaning, it has obvious defects in odor control and environmental sanitation management. These problems not only affect the quality of life of pet owners, but also pose challenges to the health of pet cats and the sanitation condition of the home environment. Therefore, it is necessary to develop a new cat toilet technology to solve the odor control and environmental sanitation problems in the prior art and improve the overall experience of pet care.
