Description
Technical Field
The invention relates to a pet article, in particular to a pet toilet.
Background
Previously pets have only been animals that a single person had to stock for silence removal or for recreational purposes. Pets are nowadays defined as animals and plants that are kept for non-economic purposes. Pets are animals and plants that are kept for mental purposes. The pet is usually kept for eliminating the dead or entertaining, and the former pets are usually mammals or birds, because the animals are developed in brain and are easy to communicate with people. To foster the popularity of pets, vast markets for pet products, such as dog foods, cat foods, kennels, cat houses, pet toys, pet litter, and the like, have evolved. The purpose of the pet toilet is to facilitate the defecation of the pet and avoid indoor pollution.
The existing pet toilet mainly comprises a cat toilet, a dog toilet and the like, and the existing pet toilet has the following ubiquitous problems: has bad taste and is difficult to clean. After defecation, the pet needs to be cleaned by the host in time, and if the pet is not cleaned, the pet is hard to clean, so that the labor intensity of the pet host is certainly increased, the excrement is manually cleaned, and the experience is quite poor. For example, the existing cat toilet is often not cleaned in time by users after the cat defecation, and the excrement stays on the surface of the cat litter for a long time and volatilizes odor. The cat litter is easily stuck to the bottom after being soaked in the excrement liquid for a long time. The sticky bottom formed by the cat litter has strong viscosity and is difficult to clean. Due to these problems, the automatic toilets have been developed.
The existing automatic cat litter box mainly comprises the following steps:
1. automatic cat lavatory of littermaid
The market time is 2016, and the basic principle is that the cat litter on the surface of the cat litter is removed by a horizontally moving claw rake and the cat litter is agglomerated. Because the claw rake is directly contacted with cat litter, the cat litter is easy to pollute, causes blockage and cannot work. Frequent cleaning is required and difficult to clean. The user experience is poor. The advantage is that automatic equipment can be purchased within thousands of yuan.
2. Automatic cat toilet easy to clean.
Imported in the united states, manufactured in china. Domestic market time 2012. The basic principle is to simulate cat litter using water washable plastic particles. After the cat urinates, the cat litter is washed by water, and then large particles are scraped out by a strainer to be washed away. And (5) drying the cat litter.
The advantages are that: placing in a toilet, and automatically flushing cat litter into a sewer. Special cat litter is used without frequent addition
Disadvantages: the toilet bowl is not cleaned up when the toilet bowl has loose feces and small particles, and the toilet bowl has heavy pollution and needs to be manually cleaned. The cat litter is automatically dried after the feces are diluted, so that the cat litter has heavy odor. The experience is poor. The toilet must be placed in the toilet, with the water tap and sewer. The consumables are more expensive, and the consumption cost of the plastic cat litter and the cleaning liquid is high. The cleaning time was long (45 minutes). The pet excrement and urine can be automatically cleaned, and the energy consumption and the water consumption are high (drying, cleaning and sand drying are needed), so that the use cost of a user is high.
