Technical Field

The invention relates to the technical field of tooth rinsers, in particular to a gland sealing piece for a tooth rinser and a manufacturing method thereof.

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, becoming "tartar accumulates in the root of the tooth, compressing and stimulating the periodontal environment, causing periodontal atrophy. Therefore, the teeth are cleaned by a tooth flushing device, a toothpick or dental floss, and a main nutrient source of dental plaque is blocked.

The tooth flusher is an auxiliary tool for cleaning the oral cavity, the teeth and the slits between the teeth are cleaned by utilizing a pulse water flow impact mode, and the emitted pressure water column not only can clean various slit holes and convex-concave-convex surfaces, but also can achieve the effects of microcosmic thorough cleaning rather than macroscopic rough cleaning of the tooth flusher, besides the function of cleaning the oral cavity of the teeth, the water flow has a massage effect on the gum, and the blood circulation of the gum is promoted to enhance the disease resistance of local tissues; and can also eliminate halitosis caused by poor oral hygiene.

The gland on the tooth flushing device has poor sealing effect, so that a sealing ring can be prepared for use together, but the sealing ring can deform and fall off due to long-term use of the sealing ring, and the deformation resistance is poor, so that the sealing performance of the gland is influenced, and therefore, the manufacturing method of the gland sealing part for the tooth flushing device is provided.
