Negative pressure massage structure and massage device for sexual stimulation

A negative pressure massage structure for sexual stimulation, comprising:

• a negative pressure generating assembly;
• a first chamber, wherein the first chamber has at least one first opening configured to be in contact with a target massage area;
• a first connection channel, wherein the first connection channel connects the first chamber and the negative pressure generating assembly, and the first connection channel and the first chamber form a first airflow channel;
• a waterproof-breathable assembly, wherein the waterproof-breathable assembly is disposed in the first airflow channel, and the waterproof-breathable assembly comprises a waterproof-breathable membrane with waterproof-breathable properties;
• and
• a first housing, wherein the negative pressure generating assembly, the first chamber, and the first connection channel are respectively disposed in the first housing;
• wherein the negative pressure generating assembly is configured to generate negative pressure at the first opening via the first airflow channel, such that the first opening exerts a stimulation effect on the target massage area.
