Description

Technical Field

[0001] This utility model relates to a hand-operated air-inflating device, and more particularly to a pressurized air-inflating pump. Background Technology

[0002] In everyday life, air mattresses, air beds, inflatable toys, and other products all contain air bladders. These air bladders are used in conjunction with hand-operated inflatable balls to inflate them. However, existing inflatable balls inflate directly, resulting in relatively low gas pressure, which fails to fully realize the comfort of inflatable products. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model provides a two-stage pressurized air pump, comprising a primary inflation chamber, a booster valve plate, a secondary inflation chamber, a booster valve plate, and an inflation valve plate. Its features are: the booster valve plate is disposed between the primary and secondary inflation chambers; the booster valve plate is disposed on the booster valve plate; and the inflation valve plate is disposed within the secondary inflation chamber. A first sealing ring is provided along the periphery of the side of the primary inflation chamber, and an air inlet is provided at the top of the primary inflation chamber. The outer ring of the booster valve plate is provided with a second sealing ring, and the inner ring is provided with a booster air hole and a booster valve plate embedding hole. The booster valve plate has a pressure transmission protrusion on the upper part of the middle ring and a booster valve plate protection block on the lower part; the secondary inflation chamber has a third sealing ring on the side periphery, an inflation valve plate embedding hole and an inflation hole in the center of the bottom, and an inflation valve plate protection block protruding on the outer side of the bottom; the first sealing ring, the second sealing ring and the third sealing ring can be fused together to achieve an external seal; the fixing part of the booster valve plate is inserted into the booster valve plate embedding hole from below, and the booster valve plate is positioned below the booster air hole; the fixing part of the inflation valve plate is inserted into the inflation valve plate embedding hole from below, and the inflation valve plate is positioned below the inflation hole.

[0004] This invention, by setting up a progressive primary inflation chamber and a secondary inflation chamber, achieves secondary pressurization during the inflation process, providing greater inflation pressure for inflatable products and significantly improving their performance.

[0014] like Figures 1 to 3 The illustrated two-stage pressurized air pump includes a primary inflation chamber 1, a booster valve plate 2, a secondary inflation chamber 3, a booster valve 4, and an inflation valve 5. The booster valve plate 2 is disposed between the primary inflation chamber 1 and the secondary inflation chamber 3. The booster valve 4 is disposed on the booster valve plate 2, and the inflation valve 5 is disposed within the secondary inflation chamber 3. A first sealing ring 11 is provided along the periphery of the side of the primary inflation chamber 1, and an air inlet 12 is provided at the top of the primary inflation chamber 1. A second sealing ring 11 is provided around the outer ring of the booster valve plate 2. The second sealing ring 21 has an inner ring with a pressurizing air hole 22 and a pressurizing valve plate embedding hole 23. A pressure transmission protrusion 24 is located on the upper part of the middle ring of the pressurizing valve plate 2, and a pressurizing valve plate protection block 25 is located on the lower part. The secondary inflation chamber 3 has a third sealing ring 31 along its side perimeter, an inflation valve plate embedding hole 33 and an inflation hole 32 at the center of its bottom, and an inflation valve plate protection block 34 protruding from the outer side of its bottom. The first sealing ring 11, the second sealing ring 21, and the third sealing ring 31 can be fused together to achieve a tight outer seal. The pressure booster valve plate 4 is fixed from below and inserted into the pressure booster valve plate recess 23, positioning the pressure booster valve plate 4 below the pressure booster air hole 22; the inflation valve plate 5 is fixed from below and inserted into the inflation valve plate recess 33, positioning the inflation valve plate 5 below the inflation hole 32; the primary inflation chamber 1, the pressure booster valve plate 2, and the secondary inflation chamber 3 are all made of soft material, wherein the thickness of the primary inflation chamber 1 is less than the thickness of the pressure booster valve plate 2 and the secondary inflation chamber 3, and when the primary inflation chamber 1 is pressurized, the pressure booster... The space formed by the valve plate 2 and the secondary inflation chamber 3 has a large supporting force, ensuring that the gas in the inflation chamber 1 can enter the secondary inflation chamber 3 through the pressurizing air hole 22 for primary inflation. When the pressure is further squeezed downwards until it acts on the pressure transmission block 24, the space formed by the pressurizing valve plate 2 and the secondary inflation chamber 3 begins to shrink, thus pressurizing the gas in the secondary inflation chamber 3 a second time. The gas then enters the air-using space sealed with the inflation pump through the inflation hole 32 at a relatively high pressure, achieving secondary inflation. During the inflation process, the pressurizing valve plate protection block 25 and the inflation valve plate protection block 34 respectively protect the pressurizing valve plate 4 and the inflation valve plate 5, ensuring sufficient clearance for smooth airflow.

[0015] This invention achieves secondary pressurization during inflation by setting up a progressive primary inflation chamber 1 and a secondary inflation chamber 3, providing greater inflation pressure for inflatable products and significantly improving their performance.
