As shown in a partially enlarged view of the conventional structure of Fig. 3, the gas plug valve 62 has the following characteristics: 'the top of the gas plug valve 62 is opened with a 621 downwardly opened in the inner volume-large space= To the 622' and the outer plug of the air plug (5) 62 is provided with a recess and is provided with a 〇tΖ ί 的 的 气缸 内 内 内 内 内 内 内 内 内 内 内 内 内 , , , , , , , , , , , , , , , , , , , Each of the chambers 622 设有 is provided with an air plug in the second middle section. The gas plug 63 is exemplified by the prior art design as having a smaller tip end = 'the head end 631 can hinder movement in the through hole 621, the air plug 63 has a bulky plug body 632 below the head end 631. The body of the plug body 632 can be used to open the joint between the 621 and the chamber 622 to form a gas tightness. After the end of the pumping stroke, the tire (10) is self-tested. After the τ square hose SQ is recirculated, it can be borrowed. The 632 abuts against the opening position of the connection between the through hole 62i and the chamber 622. Under the plug body 632, a smaller-sized sleeve portion 633 is formed for a pressure spring 64, and is supported by the pressure spring 64 below the joint portion 633 and axially abuts against the top. The force causes the air plug 63 to be normally I, upwardly abutting below the opening position of the connection between the through hole 621 and the chamber 622. Therefore, when the user starts to perform airing, the airflow enters from the position of the through hole 621, and the strong air pressure forces the plug body 632 of the air plug 63 to be pressed down and then retracted to the 201139898, and the opening is made to allow the airflow to pass downward. After being guided to the conduction port 611, the official 50 outputs the air flow. However, the conventional air lock valve 62 and the air plug 63 are designed to operate on the wire, and the resulting dead wire is produced, but in actual use, there are disadvantages. The main reason for the generation is that the plug body 632 is cylindrical in shape and is vertically inclined to the top in a tapered manner. The pressure is balanced (pressure (8) is the unit area • the force (F) of the text) (cylinder exhaust) Pressure F]y (through hole A through pressure P = reverse pressure F2 (pressure spring elastic + tire internal pressure) / (plug pressure value] can be known to meet the - set pressure (8) balance, prepare, body The ratio of the 632 pressure area to the eight 2 is larger than the aperture of the through hole.

In the through hole 621 aperture ^ position generated greater than the reverse pressure + the tire internal pressure) and then press down into the airflow, so similar to the aforementioned tapered oblique contact design 'increased user in the design of the air structure, there are The air plug of the sphere is formed as a gas-tight use of the circular arc surface and through hole of the '^ Γ二原,理下' sphere The question of airtightness is the same as the effect of the force to increase the area of the money to produce ^ ^ _ make the ball too large 'and the arc surface still produces the force to press the spherical body to disperse the effect; Please refer to the formula shown in Figure 4: The valve structure is also used in the drawing to be used under the through hole 621. However, generally the blade valve of this type is still mainly a single piece. 201139898 Soft material such as rubber is made. Therefore, under strong A_ pressure, (4) will be pressed under the through hole 621, and the pressure from the inside of the tire is too large, resulting in the pressure to form a convex end 651. Once the convex end 651 is pressed and formed, the degree of change is large, and it may be as shown in the figure B. In the repeated pumping stroke, it is easy to highlight the shape of the end 651, and the shape cannot be completely dense. Covering the opening of the through hole 621 and creating a gap to allow the airflow to pass through the state of the pressure generation, and the situation will become more severe as the shape of the convex end 651 changes more and more ΐΐΪΐ f 知 立 立 立The valve body structure 6G of P should be designed with Hanwu space.

In the design of the present invention, the circular area Ac of the dead area is at least larger than the through hole of the top cover 22. ίίΛ' f and at the same time greater than the thickness h of the valve plate is a proportional limit, so that when the pumping bay is not fluorineed, it can be pushed by the magazine 24 and the top cover 22 is airtightly formed at the lower edge of the opening of the through hole 221, and the gasket The 234 sets of the round furnace disposed on the periphery of the top 231 are not larger than the maximum circular diameter A3 of the valve piece. It is noted that the inner surface of the chamber 222 is flat around the through hole 221, and the diameter of the dead area Ae of the 23 is a flat design. When the air pump is added to the air, the force is turned. The component force is generated and the flow force can completely transmit the circular area Ac of the dead area, and the valve piece 23 is designed to abut the through hole 221 around the ring 2 end of the washer 234, thereby generating a better airtight effect and reducing The plane is required to add 1 density to the surface required for the stop, and the class of the valve piece 23...the sigh can provide the support under the washer 234 without deformation, and the face, the diameter Ac is at least greater than the top cover 22 hole 221 hole diameter & with valve handle, thickness design, can reduce the required volume ratio of the diaphragm 23 to the most - and at the same time obtain the maximum pressure proportional area, based on the aforementioned (cylinder outlet 201139898 pressure ) / (through hole diameter A,) = pressure p = reverse pressure (pressure spring force + month A) / (the principle of the circular area of the plug body pressure area Ad, the blade 23 of the present invention can be made The lowering of the required force is required to press the valve on the magazine 24 when the air is being pumped, and the maximum diameter A3 of the valve 23 is divided. Increasing the contact area of the top cover 22 which is separated by the circular diameter Ac from the through hole 221 and the inlet air flow area, so that the continuously driven air flow can maintain the position of the lower pressure valve piece 23 to the optimum air blowing effect. Referring to FIG. 9 again, the structural design of the other embodiment shown in FIG. 9 is different from the design of the preferred embodiment. The valve piece 26 of another form has a recess 261 and a ring wall 262 ′ is formed on the outer ring. The bottom of the ring wall 262 and the at least one abutting portion 2 have the same flow channel design to conduct airflow; wherein the groove 261 can be sleeved. As shown in FIG. 9A, the gasket 264 or the gasket 265 of FIG. 9B, wherein the gasket 265 is provided with a convex ring 2651, the gasket 264 and the convex ring 2651 are at the center of the valve plate 26 The top end position is slightly higher than the valve piece plus the top end position, and forms a stop area round diameter Ac. The valve piece % and the dead area round diameter of the embodiment are the same as the other structural relationships. The valve body structure of the pump of the present invention is transmitted through the valve seat, the top cover and The design of 1 can reduce the force required for pumping, and at the same time make the overall structure, the design of the replacement and maintenance more convenient, and the use of the industry, and there is no similar or only the same patent or technology disclosed. It has already met the novelty of the special specification on the special wolf, and has filed an invention patent application according to law. 201139898 [Simple diagram of the diagram] Figure 3, Figure 4, Figure 5, Figure 6, Figure 8, Figure 9 A perspective view of a partial assembly of a conventional pump.
