AI Technical Summary
The processing cost and cycle time of the air passage of existing inflation equipment are high, especially for small inflatable products with high airtightness requirements. The performance of existing inflation equipment is prone to overflow, resulting in the inability to effectively reduce production costs and cycle time.
It adopts a simple press-to-inflate valve, including an elastic airbag and a hollow connecting part, with first and second chambers inside, and first and second one-way venting plates arranged in the chambers. The one-way venting plate design realizes inflation and air intake circulation. The structure is simple and suitable for miniaturized production.
It achieves low-cost, simple-structure inflation, suitable for occasions where high inflation volume is not required, and reduces the production cost and cycle time of small inflatable products.
