Waterproof oral irrigator

A waterproof oral irrigator, comprising:

• an oral irrigator housing, wherein an outer wall of the oral irrigator housing is provided with a sliding recess;
• a push switch slidably fitted with the sliding recess, wherein the push switch is provided with a magnetic element;
• and
• a control circuit board arranged inside the oral irrigator housing, wherein the control circuit board is provided with a plurality of Hall elements, and the plurality of Hall elements are sequentially arranged at intervals along a sliding direction of the push switch,
• wherein when the push switch is sliding along the sliding recess, the push switch drives the magnetic element to move to positions sensed by the plurality of Hall elements in sequence;
• wherein the push switch comprises a plurality of abutting members;
• a limiting groove is defined on a side wall of the sliding recess, and each abutting member is slidably fitted with the limiting groove;
• wherein the push switch further comprises a push top wall and a push side wall connected to a periphery of the push top wall, wherein the push side wall is slidably fitted with the side wall of the sliding recess, and each abutting member is connected to the side of the push side wall adjacent to the side wall of the sliding recess;
• wherein a plurality of connecting holes are defined on the push side wall, and each abutting member movably passes through a corresponding connecting hole of the plurality of connecting holes;
• wherein the push switch further comprises an elastic return member configured to cause each abutting member to be in sliding fit with the limiting groove;
• wherein the push top wall and the push side wall are enclosed to form an accommodating cavity, and each abutting member comprises:
• a limiting body, a connecting body and a sliding body connected in sequence, wherein the limiting body is slidably fitted with the limiting groove, the connecting body passes through the corresponding connecting hole, and the sliding body is located in the accommodating cavity, wherein the sliding body is larger than the corresponding connecting hole in size.
