Abstract
The invention relates to a bellows type air pump, wherein four sections of angle materials are connected with the edges of two equal large square plates to form a cross shape, the two surfaces of the angle materials are equal, the angle is variable, the angle between the surface of the angle materials and the surface of the square plates is variable, the angle is freely and movably combined, the edges of four pieces of 90-degree bent flexible sheets are connected with the end parts of the angle materials to form a sealing box, the sealing box is provided with an air outlet and an air inlet, and a proper device is arranged to change the space between the square plates in a linkage way; the above is a unit. Multiple units can be connected in series in a stacked manner, and the air outlet of one air inlet is connected with the adjacent air inlet. A suitable means may be a handle on the end plate, which is pumped manually. The flexible sheet may be soft leather. When the included angle of the angle materials is 0 degree, the flexible sheet is folded in half, and the sealing box is octagonal. When the angle of the angle material is 90 degrees, the edge of the flexible sheet is attached to the end part of the angle material to form two planes, and the sealing box is in a cross shape. The flexible sheet produces little resistance to these deflections, greatly reducing the resistance to the movement of the seal box and improving the pumping performance.
Description
The invention relates to a bellows type air pump. The conventional bellows-type air pump is usually driven by manpower, and when the angle of V is changed, the ratio of the outer periphery size to the inner periphery size of the bellows is changed by using V-shaped bellows. The periphery is stretched and the inner periphery is compressed or the periphery is compressed and the inner periphery is stretched, so that resistance is formed to free movement. The stronger the vessel wall, the poorer the free mobility.
The invention aims to improve the free movement performance and has considerable strength for manual operation.
This object is achieved in the following way:
the four sections of angle bars 3 are connected with the edges of two equal large square plates 1 and 5 to form a cross shape, the two sides of the angle bars are equal, the angle is variable, the angle between the surface of the angle bars and the surface of the square plates is variable, the angle is freely and movably combined, the edges of the four flexible high-tension film blocks 4 are connected with the end parts of the angle bars to form a sealing box, the sealing box is provided with an air outlet and an air inlet, and a proper device is linked with external force to change the space between the square plates; the above is a unit.
A plurality of units can be connected in series in a stacked mode, and the air outlet of one unit is connected with the air inlet of the adjacent unit.
A suitable means may be a handle 7 on the end plate.
The flexible high tensile film may be a soft leather.
When the angle of the angle material is 0 degree, the flexible film is folded in half, and the sealing box is octagonal. When the angle of the angle bar is 90 degrees, the edge of the flexible film is attached to the end part of the angle bar to form two planes, and the sealing box is in a cross shape. The flexible film provides little resistance to these deflections, greatly reducing resistance to movement of the sealed box and improving performance.
The invention is described below with reference to the accompanying drawings:
fig. 1 is a top view of a case where the angle is 0 °. In the figure, 1 is a square panel, 2 is an air outlet, 3 is a section of angle bar, and 4 is a flexible film.
Fig. 2 is a bottom view of the angle bar at 0 °. In the figure, 5 is a square bottom plate, and 6 is an air inlet.
Fig. 3 is a top or bottom view at an angle of 90 °. In the figure, the flexible film (4) is attached to the end of the angle section (3) to form two planes.
Fig. 4 is a side view at an angle of 90 °, showing the flexible film 4 on one half.
Fig. 5 is a side view of a plurality of cells in series. In the figure, item 7 is a handle.
The flexible membrane 4 in the cassette of fig. 3 is a solid 90 ° bend, and in the plane of fig. 1 is a planar right triangle, the flexible membrane 4 changing between these two shapes, the original "square" no longer existing. The flexible high tension film may be a flexible sheet.
The flexible high tension film may be a flexible sheet.
The low resistance characteristic of the invention improves the manpower conversion efficiency and is suitable for manpower jet propulsion. The traditional bellows type air pump has large resistance and consumes extra manpower, and is not suitable for use.
