Description

Technical Field

[0001] The utility model relates to a breast pump, in particular to a heatable breast pump. Background Art

[0002] A breast pump is a tool used to extract breast milk for lactating mothers. Babies have poor sucking ability when they are just born and cannot effectively absorb milk from their mothers' breasts. A breast pump solves this problem very well. A breast pump can extract breast milk in the mother's spare time and then feed the baby. Breast pumps are easy to operate and have become a widely used maternal and child product.

[0003] When the temperature is low, the surface temperature of the breast pump is also low. The cold breast pump close to the skin will cause the milk ducts of the breast to contract due to the cold, resulting in poor milk discharge. Therefore, a breast pump with a heating function has emerged, such as a heating device for a breast pump disclosed in CN206543296U, which includes a heating component, a temperature controller and a connector. The heating component, the temperature controller and the connector are electrically connected. The heating component includes a heat-conducting cover and a heating element. The heating element is in contact with the heat-conducting cover and is fixed by a buckle. The heating component can be bent and sleeved on a breast pump. The heating element generates heat and transfers the heat to the breast pump through the heat-conducting cover.

[0004] However, the connector of the above-mentioned breast pump is external, and it needs to be connected to an external power supply when in use, and there is a long connecting line, which is relatively inconvenient. Utility Model Content
