Breast sucking cover structure of breast pump

Abstract

The invention discloses a breast sucking cover structure of a breast pump, which belongs to the field of mother and baby electric appliances, and comprises a breast sucking inner cover body component, and a support outer protection frame body, wherein the breast sucking inner cover body component comprises a big port sealing inner ring sheet, a breast protection cover body, and a cover cup connecting mouth; the breast protection cover body, the big port sealing inner ring sheet, and the cover cup connecting mouth are seamlessly bonded into an integrality through a twice plastic injection manner; the material of the big port sealing inner ring sheet and the cover cup connecting mouth adopts PPSU material, and the breast protection cover body adopts SIL liquid silica gel. Compared with the prior art, the breast sucking cover structure has the following advantages: (1) the breast sucking cover can be used without reassembling after cleaning and disinfecting, so that the defect that the breast sucking cover structure is likely to have physical ageing and damaging easily due to long-term assembly and disassembly is avoided; (2) the heat stability is good, and the breast sucking cove is not easy to deform after being disinfected under high temperature condition; (3) the airtightness is extremely good, so that the leak tightness of the integral breast pump is guaranteed.

Description

technical field [0001] The invention belongs to the field of maternity and infant appliances, and in particular relates to a breast shield structure for a breast pump. Background technique [0002] In modern life, breast pump products, as a tool for breastfeeding, are increasingly accepted by mothers who want to breastfeed their babies safely without affecting their work. In the prior art, breast pumps are generally divided into two types: manual breast pumps and electric breast pumps. No matter what type of existing breast pump, there is a breast shield. Existing breast shields are multi-component assembly structures, which generally include independent breast pads of soft material and cups of hard material, and the breast pads and cups are nested using physical structures. Its disadvantages are: (1) cleaning and disinfection need to be separated, and after disinfection, it needs to be reassembled before it can be used, which is inconvenient to use, and long-term assembly...

AI Technical Summary

Problems solved by technology

Its disadvantages are: (1) cleaning and disinfection need to be separated, and after disinfection, it needs to be reassembled before it can be used, which is inconvenient to use, and long-term assembly and disassembly are likely to cause physical aging and damage to the structure of the breast shield; Under high temperature conditions, the sterilized breast pads and cups are easily deformed, which directly affects the overall airtightness of the breast pump; (3) The structure of breast pumps currently on the market is made of PP or PC materials, and many Secondary disinfection will destroy the stability of the material; (4) In the production process, separate breast pads and cups must be assembled together, and the airtightness after assembly must be ensured, so the process requirements are quite strict
