Oral irrigator

Abstract

The invention discloses an oral irrigator which comprises a nozzle, a main shell and a moveable shell, wherein a pump component is arranged in a waterproof accommodation cavity of the main shell and communicates with the nozzle; the moveable shell is moveably connected with the main shell and is sealed by a first seal part which is positioned on the moveable shell; and the pump component communicates with a second cavity inside the moveable shell. A pressure adjusting structure is arranged on the inner side wall of the moveable shell, so that the consequence that remaining water cannot be usedas a water storage tank is at a vacuum state inside is avoided, and the utilization rate of a liquid in the water storage tank is increased; the volume can be freely increased on the basis of an inherent volume of a water tank, and not only is the volume not increased, but also the oral irrigator is convenient to carry over; the nozzle can be smartly designed and put into the water storage tank,so that is not only prevented from contamination, but also convenient to contain, takes a small space and is portable indeed; and the main shell and the moveable shell are in detachable connection, sothat the oral irrigator is convenient to maintain and clean, bacteria are not easy to propagate, and health of a user can be well facilitated.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a water flosser. Background technique [0002] Water flossing is powered by water jets to remove residual food on the teeth or between the teeth. It is an effective technical means to protect the gums, reduce the reproduction of bacteria in the oral cavity, and prevent dental and oral diseases. Most of the traditional water flossers are used in dental hospitals. Taking the patent publication number US20150072303A1 as an example, this patent discloses a technical scheme of a desktop dentist water jet device. The water storage container and the pump body are arranged on the same rack, and the nozzle Connected by a high-pressure water pipe, the advantage is that it has a large enough water storage volume and can have a lighter operating handle. The device is too bulky, not only inconvenient to carry, but also the nozzle is not removable and easily polluted. [0003] With ...

Problems solved by technology

Traditional water floss is mostly used in dental hospitals. Take the patent publication number US20150072303A1 as an example. This patent discloses a technical solution for a desktop dental water jet device. The water storage container and the pump body are arranged on the same frame, and the nozzle Connected by a high-pressure water pipe, the advantage is that it has a large enough water storage volume and can have a lighter operating handle. The device is too bulky, not only inconvenient to carry, but also the nozzle is not detachable and easily contaminated

[0003] With the improvement of living standards and the enhancement of self-care awareness, portable water floss has gradually appeared on the market. By installing a water storage container on the pump body, the effect of portability is achieved. Some water floss water storage containers use movable However, when the dental flosser is running, the air pressure of the water tank will drop under the action of the pump to form an air pressure difference with the outside world, making the inside of the water tank in a vacuum state and stopping the water tank. In situ, the remaining water in the water tank cannot be completely drained, so that the volume of the water storage container cannot be fully utilized
