在现代生活中， 吸奶器产品作为母乳哺养的工具， 越来越被既要用母 乳安全哺育婴儿、 又不影响上班的育婴母亲所接受。 现有技术中， 吸奶装 置一般分为手动吸奶器和电动吸奶器两种。现有的吸奶器无论是哪种类型， 都有一个吸乳罩。现有的吸乳罩是多部件组装结构，该结构一般包含有独立 的软性材料的护乳垫和硬性材料的罩杯， 护乳垫和罩杯利用物理结构相嵌 套。 其缺陷是： （1 ) 清洗和消毒都需要分开， 消毒过后还需要重新装配才 可以使用， 使用不方便， 而且长期组装和拆卸容易使吸乳罩结构发生物理 老化和损坏； （2 ) 由于消毒是在高温条件下进行， 消毒后的护乳垫和罩杯 都很容易产生变形， 直接影响到吸奶器整体的密封性； （3 ) 目前市场上的 吸乳罩结构采用的是 PP或 PC材料, 多次消毒会破坏材料的稳定性； （4) 在生产流程中， 要把分开的护乳垫和罩杯组装在一起， 并要保证组装后其 气密性， 因而工艺要求相当严格。 In modern life, breast-feeding products, as tools for breast-feeding, are increasingly being accepted by mothers who want to safely feed their babies with breast milk without affecting their work. In the prior art, the breast pumping device is generally classified into a manual breast pump and an electric breast pump. Regardless of the type of breast pump available, there is a breastshield. The existing breastshield is a multi-component assembly structure which generally comprises a separate soft material breast pad and a hard material cup, and the breast pad and the cup are embedded with a physical structure. The defects are as follows: (1) Both cleaning and disinfection need to be separated. After disinfection, they need to be reassembled before they can be used. It is inconvenient to use, and long-term assembly and disassembly can easily cause physical aging and damage to the structure of the breastshield; (2) Because disinfection is Under high temperature conditions, the breast pad and cup after disinfection are easily deformed, which directly affects the overall sealing of the breast pump; (3) The current structure of the breastshield is made of PP or PC material, Secondary disinfection will destroy the stability of the material; (4) In the production process, separate breast pads and cups should be assembled together, and the airtightness after assembly should be ensured, so the process requirements are quite strict.
