Abstract

The micro pump comprises a pump shell, a magnet, a buffer piece, a first electromagnet and a second electromagnet, the pump shell is provided with a first cavity and a second cavity which are communicated with each other, a water inlet and a water outlet are formed in one end of the pump shell, and the water inlet and the water outlet are both communicated with the first cavity; the first cavity is far away from the second cavity; the piston comprises a piston rod and a piston head connected to one end of the piston rod, the piston head is slidably arranged in the first cavity, and at least part of the piston rod is located in the second cavity. The first electromagnet and the second electromagnet are fixed in the second cavity at intervals in the axial direction of the piston rod, and the piston rod slidably penetrates through inner rings of the first electromagnet and the second electromagnet; the magnet is fixedly connected to the piston rod and located between the first electromagnet and the second electromagnet. Buffering pieces are arranged between the first electromagnet and the magnet and between the second electromagnet and the magnet. The micro pump provided by the invention is long in service life.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a micropump and a dental flosser. Background technique [0002] As a new type of oral cleaning appliance, the dental flosser has been proven in various tests for its effectiveness in periodontal care, gingivitis treatment, deformity correction and crown restoration. [0003] The dental flosser pressurizes the water through a micro-pump to generate an ultra-fine high-pressure pulsed water column. The water column scours any part of the oral cavity through the nozzle, including tooth spaces and deep gums that are not easily accessible by toothbrushes, dental floss, and toothpicks. Strongly remove food residues and harmful bacteria accumulated in the gaps between the teeth that toothbrushes and dental floss cannot reach, effectively prevent tooth decay, gingivitis, calculus and periodontitis, and effectively clean up dental plaque on the surface of teeth to keep the mouth clean, It m...
