Description

Technical Field

[0001] The utility model belongs to the technical field of oral irrigators, and in particular relates to a portable oral irrigator. Background Art

[0002] With the development of science and technology and the improvement of health awareness, water flossers are constantly being promoted and advertised as a highly effective oral care product. Water flossers are an auxiliary tool for cleaning the oral cavity, which uses pulsed water flow to clean teeth and interdental spaces. Just as people know that cars can be easily cleaned with high-pressure water guns, water flow with appropriate pressure has long been proven to effectively clean people's teeth and oral cavity. The cleaning effect of water flossers is mainly achieved by using the impact force of a high-speed water column ejected under a certain pressure.

[0003] Currently on the market, most of the water flossers are mainly composed of several main parts such as a handle, a nozzle, a water tank, a circuit board, and a motor. Handle: The handle of the water flosser is the part that the user holds in his hand, which is used to control the working switch and is simple and convenient to operate. Nozzle: The nozzle of the water flosser is the part used to flush water to the gaps between teeth and the tooth surface. The nozzle includes shapes such as a standard nozzle, an orthodontic nozzle, and a periodontal pocket nozzle, and is detachably connected to the handle. Water tank: The water tank of the water flosser is the part that stores water. The water tank has different capacities and can be selected according to personal needs. Circuit board and motor: The circuit board and motor inside the water flosser are responsible for controlling the operation and power output of the water flosser.

[0004] However, when using an oral irrigator, users often place it in the bathroom. When not in use, the users do not remove the nozzle, and the nozzle is directly exposed to the air. When not in use for a long time, dust will accumulate on the nozzle. In addition, if the user takes the oral irrigator on a business trip or travel, the user often needs to remove the nozzle separately and place it in a special box. When using the oral irrigator, the user needs to take the nozzle out of the special box and install it again, which makes the operation process more cumbersome.

[0005] Therefore, how to solve the problem that the nozzle of the existing water flosser is easy to accumulate dust and is inconvenient to store is a technical problem that the existing technical personnel urgently need to solve. Utility Model Content
