Abstract

The invention relates to a one-way valve structure, a pump and a cleaning utensil. The cleaning utensil comprises a pump body or the one-way valve structure. The one-way valve structure comprises a first valve body, a second valve body and a first valve block. The first valve body is provided with a first end face, the first valve body is provided with a first channel penetrating through the firstend face, and an outlet of the first channel is formed in the first end face. A second channel is formed in the second valve body in a penetrating manner, a first avoiding cavity is formed in an inlet of the second channel, the inlet of the second channel is an inlet of the first avoiding cavity, and the second valve body is connected with the first valve body, so that the outlet of the first channel and at least part of the first end face are opposite to the inlet of the avoiding cavity. The first valve block is fixedly connected with the first valve body and / or the second valve body, the first valve block is provided with a first water retaining part in limiting fit with the first end face, and the first water retaining part is movably arranged between the outlet of the first channel and the inlet of the first avoiding cavity.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a one-way valve structure, a pump body and a cleaning appliance. Background technique [0002] Water floss, also known as dental flosser, is a cleaning device for cleaning the oral cavity, which cleans teeth and teeth gaps by using the impact of water flow. According to the structure, dental flossers can be divided into two categories: electric dental flossers and faucet dental flossers. The structure of an electric flosser mainly includes a water pump, a water tank, a body, and a nozzle; the structure of a faucet flosser mainly includes a connector and a nozzle connected to a faucet. In traditional electric flossers, a duckbill valve is mostly installed on the water pump to prevent water from flowing back into the water tank, but the structure of the duckbill valve is complicated and the manufacturing cost is high. Contents of the invention [0003] Based on this, it is neces...
