Description
Technical Field
The utility model relates to a pet drinking water's technical field, in particular to pet water dispenser of automatically cleaning and automatic water changing.
Background
Along with the improvement of living standard of people, more and more families for raising pets, cats, dogs and other pets as good partners in life of people, and the problems in the aspect of diet and health are more and more valued by people. The water source is indispensable in food, and people need regularly change clean drinking water for the pet. With the development of economy and technology, automatic feeding machines and pet water dispensers are available to liberate manpower.
As a result of the discovery that a slippery mucous layer always exists on the wall of a pet water bowl, it is known that this is actually a Bacterial biofilm (or Bacterial biofilm) that is a mass of Bacterial aggregated membrane-like material formed by bacteria adhering to a contact surface, secreting polysaccharide matrix, fibrin, lipoprotein, etc., and wrapping themselves around them. The bacterial biofilm is a life phenomenon that bacteria adapt to natural environment and are beneficial to living, and can continuously attract, breed and differentiate more bacteria. The bacterial biofilm on the wall of the water bowl for the pet is mostly formed by dust in the environment and bacteria accumulated in the mouth when the pet drinks water, and the source cannot be eradicated. The higher the temperature, the faster the bacterial biofilm growth.
Therefore, the stainless steel pet drinking bowl needs to be cleaned at least every day, and is not simply added with water, otherwise the bacterial content in water can be greatly increased, the drinking desire of the pet is slightly influenced, and even the pet suffers from dyspepsia, urinary system diseases and the like.
One of the common pet water dispensers at present adopts an inverted bucket, and when the water level in a drinking bowl is lower than a certain value, drinking water is supplemented by utilizing the action of gravity and air pressure; the other is to adopt a water circulation structure, the water in the water tank flows out in a fountain-like mode, a 'living water' vision is created to attract the pet to drink, actually, the water circulation is not a new water source, and even if some filter screens are added in the water circulation tank, the filtered dirt is still soaked in the water to pollute the water. The structure has obvious defects, the water circulation structure is complex, the water circulation structure has a plurality of dead angles, the water circulation structure is a hotbed for bacterial reproduction, and even if the water circulation structure is manually cleaned, the water circulation structure cannot be thoroughly cleaned due to the complex structure.
The common pet water dispensers in the prior art mainly realize the functions of supplementing water or attracting pets, and do not have the functions of self-cleaning and automatic water changing. If the pet owner is busy or even goes on a business trip, the water dispenser can not meet the requirement of a healthy water source basically.
