Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps for oral irrigators, and in particular relates to a water pump for oral irrigators with the function of reducing transmission noise. Background Art

[0002] At present, the cylindrical shaft supporting the crown gear in the punch water pump cannot ensure the distance between the upper and lower covers. When the upper and lower covers are deformed or squeezed by external force, the distance will be even greater. If the gap between the connecting rod and the upper and lower crown gears is too large, noise will be generated. If it is too small, friction will be generated, and power consumption will increase. Utility Model Content

[0003] The purpose of the present utility model is to solve the above-mentioned problems and to provide a water pump for a water flosser with the function of reducing transmission noise.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a water pump for a water flosser with the function of reducing transmission noise, which includes a lower cover, an upper cover, a motor, a pinion, an adjusting shaft mechanism, a crown gear, a connecting rod and a diaphragm. The upper cover is clamped on the lower cover, the adjusting shaft mechanism connects the upper cover and the lower cover, the diaphragm is installed in the lower cover and separates the interior of the lower cover from the pump chamber, the crown gear is hinged on the adjusting shaft mechanism, the connecting rod connects the crown gear and the diaphragm, the crown gear drives the connecting rod to swing, the motor is installed in the lower cover, the pinion is installed on the driving end of the motor, and the pinion is meshed with the crown gear.

[0005] As a further description of the above technical solution:

[0006] The adjusting shaft mechanism includes a central shaft and a nut. The central shaft passes through the lower cover and the upper cover. The nut is screwed on the end of the central shaft and abuts against the upper cover.

[0007] As a further description of the above technical solution:

[0008] The end of the central shaft is provided with a step, and the step abuts against the lower cover.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0010] In the utility model, the upper cover and the lower cover are clamped by adopting an adjusting shaft mechanism, so that the distance between the upper and lower covers can be strictly controlled and is no longer affected by external forces, thereby effectively reducing transmission noise and water pump power consumption.
