The assembled gas pump 12 forms a first chamber 127b between the cover plate 126 and the resonant plate 122.

In the present embodiment, the resonator plate 122 of the gas pump 12 of the present invention has a gap g0 between the piezoelectric actuator 123 and the conductive material 123, for example, a conductive adhesive, but does not For this reason, the resonance piece 122 and the convex portion 1231e of the suspension plate 1231 of the piezoelectric actuator 123 are maintained at a depth of a gap g0, thereby guiding the airflow to flow more rapidly, and the suspension plate 1231 is The convex portion 1231e is kept at an appropriate distance from the resonant plate 122 to reduce the mutual contact interference, which causes the noise to decrease. In other embodiments, the height of the outer frame 1232 can be increased by adding the high voltage electric actuator 123 to The resonator piece 122 is added with a gap when assembled, but is not limited thereto. Thereby, when the piezoelectric actuator 123 is driven to perform the air collecting operation, the gas system is first collected by the opening portion 1263 of the cover plate 126 to the confluence chamber 127a, and further flows through the hollow hole 1220 of the resonance piece 122 to the first A chamber 127b is temporarily stored. When the piezoelectric actuator 123 is driven to perform an exhaust operation, the gas system first flows from the first chamber 127b through the hollow hole 1220 of the resonator 122 to the confluence chamber 127a, and the gas is supplied. The shoelace airbag 10 is introduced into the tongue airbag 11.

The operation flow of the gas pump 12 in this case is further described below. Please refer to FIGS. 8A-8D, which are schematic diagrams of the operation of the gas pump in the preferred embodiment of the present invention. First, as shown in FIG. 8A, the structure of the gas pump 12 is as described above, and is sequentially covered by the cover plate 126, another insulating sheet 1242, the conductive sheet 125, the insulating sheet 1241, the piezoelectric actuator 123, and the resonant sheet 122. The stacked assembly is positioned with a gap g0 between the resonant plate 122 and the piezoelectric actuator 123, and the resonant plate 122 and the sidewall 1261 of the cover 126 collectively define the confluent chamber 127a on the resonant plate 122 and The piezoelectric actuator 123 has a first chamber 127b between them. When the gas pump 12 has not been driven by a voltage, the position of each element is as shown in Fig. 8A.

Next, as shown in Fig. 8B, when the piezoelectric actuator 123 of the gas pump 12 is vibrated upward by the voltage, the gas enters the gas pump 12 from the opening 1263 of the cover plate 126 and is collected into the confluence. The chamber 127a then flows upward into the first chamber 127b via the hollow hole 1220 on the resonator piece 122, and the resonance piece 122 is resonated by the resonance of the suspension plate 1231 of the piezoelectric actuator 123. That is, the resonator piece 122 is deformed upward, that is, the resonator piece 122 is slightly convex upward at the hollow hole 1220.

Thereafter, as shown in FIG. 8C, at this time, the piezoelectric actuator 123 is vibrated downward to the initial position, at which time the floating portion 1231e of the suspension plate 1231 of the piezoelectric actuator 123 is close to the resonance plate 122. The portion is slightly convex upward at the hollow hole 1220, thereby causing the gas in the gas pump 12 to temporarily accumulate in the upper chamber 127b of the upper half.

Further, as shown in FIG. 8D, the piezoelectric actuator 123 vibrates downward again, and the resonance piece 122 is vibrated by the vibration of the piezoelectric actuator 123, and the resonance piece 122 is also vibrated downward. The downward deformation of the resonator piece 122 compresses the volume of the first chamber 127b, thereby causing the gas in the upper half of the first chamber 127b to push to flow to both sides and through the gap 1234 of the piezoelectric actuator 123 to circulate downward. The compressed air is discharged to the hollow hole 1220 of the resonator piece 122 to form a compressed gas flowing through the air guiding end opening 204 to the first guiding cavity 202 of the carrier 20. It can be seen from this embodiment that when the resonant plate 122 performs vertical reciprocating vibration, it can be increased by the gap g0 between the resonant piece 122 and the piezoelectric actuator 123 to increase the maximum distance of its vertical displacement, in other words, The gap g0 provided between the vibrating plate 12 and the piezoelectric actuator 123 allows the resonance piece 122 to generate a larger displacement up and down when it resonates.

Finally, the resonator piece 122 will return to the initial position, that is, as shown in FIG. 8A, and then continue to circulate in the order of FIG. 8A to FIG. 8D through the above-described operation flow, and the gas will continuously pass through the opening portion 1263 of the cover plate 126. The flow into the confluence chamber 127a, and then into the first chamber 127b, and then into the confluence chamber 127a by the first chamber 127b, so that the airflow continuously flows into the tongue airbag 11 by the lace airbag 10, thereby stably transmitting the gas. . In other words, when the gas pump 12 of the present invention operates, the gas system sequentially flows through the opening portion 1263 of the cover plate 126, the confluence chamber 127a, the first chamber 127b, the confluence chamber 127a, and the gas nozzle 16, so the present case The gas pump 12 can pass through a single component, that is, the cover plate 126, and is designed by using the opening portion 1263 of the cover plate 126, thereby reducing the number of components of the gas pump 12 and simplifying the overall process.

The confluence is concentrated to the central recess 1211 to effectively converge the gas to the hollow bore 1220 of the resonator plate 122 to transfer the gas to the interior of the first gas pump 12. Therefore, the air inlet plate 121 has an integrally formed air inlet hole 1210, a bus bar hole 1212 and a central recess portion 1211, and a confluent chamber corresponding to a confluent gas is formed at the central recess portion 1211 for temporarily storing the gas.
