Description

Novel leakage-proof backflow water pump for tooth flushing device

Technical Field

The utility model relates to a water pump technical field specifically is a novel leak protection backward flow water pump is used to tooth ware towards.

Background

The tooth-rinsing device is a novel oral cavity cleaning appliance, is widely applied, and is a necessary sanitary product for many families in Europe and America. At present, the tooth flusher has entered China, and many people gradually like the comfortable and functional tooth and oral cavity cleaning health-care product. Its efficacy in periodontal health, treating gingivitis, correcting deformity and repairing dental crowns has been demonstrated in various tests. In developed countries, tooth rinsers have already entered the market as early as forty years ago and become a necessary daily necessity for families.

The tooth flushing device pressurizes water through the pump body, can generate superfine high-pressure pulse water columns, and can enable the high-pressure pulse water columns to flush any position of the oral cavity without obstacles through the nozzle, including tooth gaps and deep gum which are not easy to reach by toothbrushes, dental floss and toothpicks. Can effectively clean dental plaque on the surface of teeth, keep the oral cavity clean and refresh people. Cleaning tongue coating, and removing oral odor. Can strongly remove food residue and harmful bacteria trapped in the gap between teeth which can not be reached by toothbrush and dental floss, and effectively prevent dental caries, gingivitis, dental calculus and periodontitis. Massage and stimulate gingiva, improve blood circulation, relieve toothache, and inhibit gingival bleeding.

However, because the existing water pump of the tooth flushing device mostly adopts a reciprocating piston structure, abrasion inevitably occurs between the piston and the pump cavity, particularly, the transmission rod can swing up and down under the driving of the eccentric wheel, so that the local stress is larger, the abrasion is more serious, the water pump can leak after being used for a period of time, the performance of the water pump is reduced, and in serious cases, a circuit board can be damaged and leak electricity due to water leakage, and the personal safety can be even endangered.
