Description

Technical Field

[0001] The utility model relates to the field of oral irrigators, and in particular to an oral irrigator with a replaceable water tank. Background Art

[0002] Brushing teeth is the most common dental care behavior. However, most toothbrushes cannot allow toothpaste to penetrate into the gaps, grooves and cracks of the occlusal surface. Therefore, an oral irrigator is needed as an auxiliary tool for toothbrushes to clean teeth. An oral irrigator generally includes an oral irrigator body and a nozzle detachably connected to the oral irrigator body. The oral irrigator body includes a water pump, which can suck the cleaning liquid and spray the cleaning liquid through the nozzle at a certain pressure, so as to clean the places that are difficult to clean with a toothbrush, such as the gaps between teeth and the gingival sulcus.

[0003] The Chinese patent with publication number CN213310500U provides a water flosser, including a housing, a water flossing mechanism, a main water tank, a water suction pipe and a nozzle. A connection part for connecting a plurality of water tanks is provided at the lower part of the housing. The water flossing mechanism is provided in the housing. The main water tank is detachably provided on the housing. The water suction pipe is provided at the connection part and can extend into the main water tank, and the water suction pipe is connected to the water flossing mechanism. The nozzle is connected to the water flossing mechanism, and the nozzle extends out of the housing.

[0004] By providing a connecting portion at the lower part of the shell, the connecting portion can be used to connect a mineral water bottle or other replacement water tank for use. Although this solves the problem of having to carry a large water tank when taking the water flosser out, in general, users prefer to use the water tank that comes with the water flosser rather than a mineral water bottle. Since the capacity of the water tank is basically within 200 ml, due to different usage habits of consumers, some people only need to add water once, some people need to add water multiple times, and some people need to add water repeatedly. In this disclosed patent, the water tank needs to be removed from the connecting portion before water can be added to the water tank, which is inconvenient to use. Utility Model Content
