Description

Technical Field

[0001] The utility model relates to the technical field of oral irrigators, in particular to an ultra-quiet oral irrigator. Background Art

[0002] An oral irrigator is an auxiliary tool for cleaning the oral cavity. It is a tool that uses pulsed water flow to clean teeth and interdental spaces. At present, most oral irrigators on the market are driven by DC carbon brush motors. The gears are rotated on the body, and the center of the gears has a cam. The motor drives the gears to rotate through gear transmission. When the cam rotates, it drives the piston to reciprocate, thereby pumping and spraying water. This driving method of the oral irrigator has the problems of high noise, short service life, and high maintenance cost. The assembly process is relatively cumbersome and the production efficiency is low, which needs to be improved. Summary of the invention

[0003] The problem to be solved by the utility model is to provide an ultra-quiet oral irrigator, which reduces noise, increases service life, simplifies the assembly process, and improves production efficiency.

[0004] To solve the above technical problems, an ultra-quiet water flosser provided by the utility model includes a linear drive mechanism and a water inlet and outlet mechanism; the linear drive mechanism includes a coil bracket, a coil wound on the outer ring of the coil bracket, a linear output shaft axially movably arranged in the coil bracket, and a magnet arranged on the linear output shaft; the water inlet and outlet mechanism includes a pump body and a piston, the pump body includes a piston cylinder, inlet and outlet water pipes connected to one end of the piston cylinder, a water inlet pipe connected to the inlet and outlet water pipes, and a water outlet pipe connected to the inlet and outlet water pipes, the piston is movably arranged in the piston cylinder, one end of the linear output shaft is fixedly connected to the piston, a water inlet check valve is arranged in the water inlet pipe, and a water outlet check valve is arranged in the water outlet pipe.

[0005] Preferably, the coil support comprises a cylindrical portion and end face portions respectively connected to both ends of the cylindrical portion, a sleeve matching the linear output shaft is provided through the center of the end face portions, and the linear output shaft is movably provided in the sleeve.

[0006] Preferably, the magnet is a ring magnet.

[0007] Preferably, the distance between the outer edge of the magnet and the inner edge of the cylindrical portion is 8 mm.

[0008] The beneficial effects of the utility model are as follows: the utility model provides an ultra-quiet water flosser, which can form a magnetic field by passing electricity through the coil, and the magnet will be subjected to force under the action of the magnetic field of the coil. By switching the current direction of the coil, the direction of the magnetic field of the coil can be changed, thereby driving the linear output shaft to reciprocate along the axial direction of the coil bracket, and the piston will perform piston motion in the piston cylinder driven by the linear output shaft. When the linear output shaft drives the piston to move inward, the piston cylinder is in an intake state, the water inlet check valve will automatically open, the water outlet check valve will automatically close, and the water flow can enter the piston cylinder through the water inlet pipe; when the linear output shaft drives the piston to move outward, the piston cylinder is in an exhaust state, the water outlet check valve will automatically open, the water inlet check valve will automatically close, and the water in the piston cylinder can be discharged through the water outlet pipe, thereby realizing the circulation action of pumping and draining water. It has a simple structure, is easy to assemble, can improve production efficiency, reduce the size of the water flosser, and has the advantages of low noise, long service life, and easy maintenance.

[0016] When used specifically, a magnetic field can be formed by passing electricity through the coil 12, and the magnet 14 will be subjected to force under the magnetic field of the coil 12. By switching the direction of the current of the coil 12, the direction of the magnetic field of the coil 12 can be changed, thereby driving the linear output shaft 13 to reciprocate along the axial direction of the coil support 11, and the piston 22 will perform piston motion in the piston cylinder 210 driven by the linear output shaft 13.
