Nozzle and tooth flushing device

Technical Field

The utility model relates to a wash tooth ware technical field, especially relate to a nozzle and wash tooth ware.

Background

The food debris lodged in the crevices of the teeth, in addition to being uncomfortable and carrying bacteria itself, is more harmful in that it provides nutrients to the plaque. If not removed in time, the plaque is easily calcified, becomes tartar to accumulate in the root of the tooth, stresses and stimulates the periodontal environment, and causes periodontal atrophy. Therefore, cleaning the gaps between teeth by using a tooth flushing device, or a toothpick or a dental floss is a main means for blocking the nutrient sources of dental plaque.

The tooth flusher is an auxiliary tool for cleaning the oral cavity, utilizes a pulse water flow impact mode to clean teeth and tooth gaps, and the emitted pressure water column not only can clean various gap holes and convex-concave-convex surfaces, but also can achieve the effect of microscopic thorough cleaning instead of macroscopic rough cleaning. The tooth washing device has the function of cleaning the oral cavity, and the water flow has the function of massaging the gum, promotes the blood circulation of the gum, enhances the disease resistance of local tissues and can eliminate halitosis caused by poor oral hygiene.

The tooth flushing device pressurizes water through the pump body, and can generate ultrafine high-pressure pulse water columns of 800 times per minute and 1600 times per minute, and the designed and exquisite nozzle can enable the high-pressure pulse water columns to flush any parts of the oral cavity without obstacles, including tooth brushes, dental floss and toothpicks which are not easy to clean teeth gaps and deep gums.

Traditional towards tooth ware is all cleaned the tooth with the rivers of taking the pulse effect, and the water pressure that the water pump produced is all come from to clear dynamics, and water pressure is big more, and clean effect is better, but otherwise the oral cavity that the increase of dynamics can give people brings the discomfort and even brings the damage for the oral cavity.
