Detailed Implementation Methods

[0060] The embodiments that embody the features and advantages of this invention will be described in detail in the following description. It should be understood that this invention can have various variations in different forms, all of which do not depart from the scope of this invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit this invention.

[0061] Please see FIG. 1A , FIG. 1B , FIG. 1C , FIG. 2A and FIG. 4 As shown, this invention provides a gas transmission device, comprising a body 1 and multiple actuation units. The body 1 includes a base 11 and a top cover 12, which seal each other to form a receiving groove 13. The base 11 has an air inlet 11a, and the top cover 12 has an air outlet 12a. The receiving groove 13 communicates with the air inlet 11a and the air outlet 12a. The body 1 also includes multiple channel partitions 14, which separate the receiving groove 13 to form multiple interconnected partitioned receiving grooves. In this embodiment, there are three partitioned receiving grooves, forming a first partition. The body 1 includes a receiving groove 13a, a second dividing receiving groove 13b, and a third dividing receiving groove 13c; and the body 1 includes a plurality of support members 15 positioned on the channel partition 14, maintaining a spaced channel 16 with the inner surface 1a of the body; furthermore, the body 1 also includes a plurality of wiring outlet holes 1b communicating with the plurality of dividing receiving grooves, that is, each wiring outlet hole 1b is respectively connected to the first dividing receiving groove 13a, the second dividing receiving groove 13b, and the third dividing receiving groove 13c.

[0062] In the present embodiment, the plurality of actuating units is three in total, and is distinguished as a first actuating unit 2a, a second actuating unit 2b, and a third actuating unit 2c. Each of the actuating units comprises an actuating body 21 and a valve body 22, and the passage partition 14 and the support 15 are used to support and position an actuating unit, i.e. the passage partition 14 and the support 15 are used to support and position the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c respectively. In addition, the plurality of actuating units are arranged in a plurality of separate accommodating grooves, and two adjacent actuating units are arranged in the separate accommodating grooves in a reverse manner, so as to maintain a series connection structure in which the valve body 22 of one of the actuating units is in communication with the actuating body 21 of the other adjacent actuating unit. The actuating body 21 of the actuating unit at the start end of the series connection structure corresponds to the gas inlet end 11a of the base body 11, and the valve body 22 of the actuating unit at the terminal end of the series connection structure corresponds to the gas outlet end 12a of the top cover 12. In this way, gas can enter the plurality of separate accommodating grooves from the gas inlet end 11a, be transmitted through the series connection structure of the plurality of actuating units to pressurize the gas, and then be discharged from the gas outlet end 12a. The gas transmission device thus formed has an output pressure of 250㎜Hg-450㎜Hg and a gas flow rate of 1L / min-3.5L / min, and is characterized by high output pressure, large gas flow rate, and low noise.

[0063] In the present embodiment, the three actuating units are respectively arranged in the three separate accommodating grooves, namely, the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c are respectively arranged in the first separate accommodating groove 13a, the second separate accommodating groove 13b, and the third separate accommodating groove 13c. The first actuating unit 2a and the second actuating unit 2b are arranged in the first separate accommodating groove 13a and the second separate accommodating groove 13b in a mutually inverted manner. The second actuating unit 2b and the third actuating unit 2c are arranged in the second separate accommodating groove 13b and the third separate accommodating groove 13c in a mutually inverted manner. The valve body 22 of the first actuating unit 2a is in communication with the actuating body 21 of the second actuating unit 2b, and the valve body 22 of the second actuating unit 2b is in communication with the actuating body 21 of the third actuating unit 2c, thereby forming a series connection structure. The actuating body 21 of the first actuating unit 2a corresponds to the air inlet end 11a of the base body 11, and the valve body 22 of the actuating unit at the terminal end of the series connection structure corresponds to the air outlet end 12a of the top cover 12, namely, the valve body 22 of the third actuating unit 2c at the terminal end of the series connection structure corresponds to the air outlet end 12a of the top cover 12. In this way, the gas enters the first separate accommodating groove 13a, the second separate accommodating groove 13b, and the third separate accommodating groove 13c through the air inlet end 11a, is transmitted by the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c in series connection structure, is pressurized, and is then discharged from the air outlet end 12a. The gas transmission device with an output pressure of 250㎜Hg~450㎜Hg and a gas flow rate of 1L / min~3.5L / min, high output pressure, large gas flow rate, and low noise is formed.

[0064] Of course, the gas transmission device of the present case tends to be miniaturized, maximized in flow rate, and quiet. In the design consideration, the body 1 with a width of 24~26㎜, a length of 70~75㎜, and a height of 3~4㎜ excluding the height of the air inlet end 11a and the air outlet end 12a is used to form the gas transmission device. In the present embodiment, the body 1 with an optimal width of 25㎜, an optimal length of 73㎜, and an optimal height of 3.5㎜ excluding the height of the air inlet end 11a and the air outlet end 12a is used to form the gas transmission device.

[0065] Please also refer to FIG. 2A , FIG. 2B , and FIG. 3A to FIG. 3CAs shown, the actuating unit comprises an actuating body 21 and a valve body 22. The actuating body 21 comprises an actuating plate 211, a frame 212, and an actuating assembly 213. The actuating plate 211 is stacked on the valve body 22 and has a plurality of actuating through holes 211a. The frame 212 is stacked on the actuating plate 211. The actuating assembly 213 is in a rectangular shape, stacked on the frame 212, and comprises an air inlet plate 2131, a piezoelectric element 2132, an insulating frame 2133, and a conductive frame 2134. The air inlet plate 2131 has a plurality of air inlet holes 2131a. The air inlet plate 2131a defines an actuating area 2131b and a fixed area 2131c on the plane thereof. The actuating area 2131b is surrounded by the air inlet holes 2131a. The fixed area 2131c is outside the air inlet holes 2131a. The piezoelectric element 2132 is disposed on the actuating area 2131b of the air inlet plate 2131. The insulating frame 2133 is disposed on the fixed area 2131c of the air inlet plate 2131. The conductive frame 2134 is disposed on the insulating frame 2133. The conductive frame 2134 has an electrode 2134a and a pin 2134b. The pin 2134b contacts the piezoelectric element 2132. The electrode 2134a is connected to an external wire. The air inlet plate 2131 itself is made of conductive material and is in electrical contact with the piezoelectric element 2132. The frame 212 is connected to another wire, thereby completing the driving circuit of the actuating assembly 213. The gas transmission device of the present application is connected to the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c by a plurality of wires. The plurality of wires are sealed by glue. The plurality of wires are connected to a driving circuit. The driving circuit sends driving signals (driving voltage and driving frequency) to the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c through the plurality of wires. One wire is transmitted to the piezoelectric element 2132 through the electrode 2134a and the pin 2134b of the conductive frame 2134. Another wire is transmitted to the piezoelectric element 2132 through the frame 212 and the air inlet plate 2131. The piezoelectric element 2132 receives the driving signals and deforms, thereby driving the actuating assembly 213 to move up and down. FIG. 3B to FIG. 3C As shown.

[0066] In the embodiment, as FIG. 3A to FIG. 3CAs shown, when the piezoelectric element 2132 receives a driving signal (driving voltage and driving frequency), it converts electrical energy into mechanical energy by the inverse piezoelectric effect, controls the deformation amount of the piezoelectric element 2132 according to the size of the driving voltage, and controls the deformation frequency of the piezoelectric element 2132 by operating the driving frequency, so that the deformation of the piezoelectric element 2132 drives the actuating assembly 213 to start transmitting gas.

[0067] The shape of the actuating assembly 213 described above is rectangular, and in the specific embodiment, the shape of the actuating assembly 213 is square. In the same device peripheral size, the actuating assembly 213 adopts a square appearance design, and the gas inlet plate 2131, the piezoelectric element 2132, the insulating frame 2133, and the conductive frame 2134 formed by the actuating assembly 213 are also square, which has the advantage of power saving compared with the traditional known circular actuating assembly design. The comparison of power consumption is shown in Table 1 as follows:

[0068] Table 1

[0069]

[0070]

[0071] Therefore, the actuating assembly 213 is a capacitive load operating at resonance frequency, and its power consumption increases with the increase of frequency. However, since the resonance frequency of the square designed actuating assembly 213 is significantly lower than that of the circular actuating assembly, its relative power consumption is also significantly lower. That is, the square designed actuating assembly 213 adopted in the present application has the advantage of power saving compared with the previous circular actuating assembly design.

[0072] Please read FIG. 2A , FIG. 2B and FIG. 3A to FIG. 3CAs shown, the valve body 22 comprises an air outlet plate 221, a valve plate 222, and a valve body plate 223 stacked in each of the partitioned accommodation grooves 13a, 13b, 13c. The valve plate 222 is located between the air outlet plate 221 and the valve body plate 223. The air outlet plate 221 has a plurality of air outlet holes 221a. The valve body plate 223 has a plurality of valve plate through holes 223a corresponding to the actuating through holes 211a of the actuating plate 211. The valve plate 222 has a plurality of valve holes 222a arranged in a staggered manner with the valve plate through holes 223a. The valve holes 222a are arranged corresponding to the air outlet holes 221a. The valve plate through holes 223a, the valve holes 222a, and the air outlet holes 221a of the valve body 22 are located below the actuating area 2131b surrounded by the air inlet holes 2131a of the air inlet plate 2131. When the piezoelectric element 2132 drives the air inlet plate 2131, the valve plate through holes 223a and the valve holes 222a are arranged in a staggered manner. When the air flow is in the forward direction, the valve body 22 operates in the open flow path. When the air flow is in the reverse direction, the valve body 22 operates in the closed flow path, preventing reverse flow and generating unidirectional flow. In this embodiment, the air outlet plate 221 and the valve body plate 223 are metal plates, and the valve plate 222 is a flexible film with a thickness of about 0.4-0.6 microns (μm), preferably 0.5 microns (μm). In this embodiment, the valve plate 222 is a polyimide film, but this is not limited.

[0073] The valve holes 222a are arranged in a staggered manner with the valve plate through holes 223a, so that the valve plate 222 can close the valve plate through holes 223a. The valve holes 222a are arranged corresponding to the air outlet holes 221a, and the diameter d2 of the valve holes 222a is greater than or equal to the diameter d1 of the air outlet holes 221a. The design of the air outlet holes 221a allows the valve body 22 to open the flow path, and the large flow of air is quickly discharged through the valve holes 222a and the air outlet holes 221a. The air outlet plate 221 has a recess 221b formed by surface depression, and the valve plate 222 covers the air outlet plate 221, so that the valve plate 222 and the recess 221b of the air outlet plate 221 maintain a distance G. The ratio between the distance G and the thickness of the air outlet plate 221 is between 1:2 and 2:3, about 40-70 microns (μm), and in this embodiment, the optimal distance G is 60 microns (μm). The design of the valve body 22 allows the valve plate 222 to close the valve plate through holes 223a when it is biased towards the valve body plate 223, and the valve body operates in the closed flow path (as shown in FIG. 2B). FIG. 3Bas shown). When the valve piece 222 is biased towards the air outlet plate 221, the valve piece 222 is able to vibrate the airflow in the gap G, and the airflow (the path indicated by the arrow) is quickly discharged through the air outlet hole 221a via the valve hole 222a, and the valve body 22 is in the open flow path mode (as shown) FIG. 3C The valve body 22 is designed to prevent backflow and generate a large flow control effect of one-way airflow.

[0074] As shown in FIG. 2A to FIG. 2B As shown in the above, the actuating plate member 211 is fixed to the valve body plate member 223, and the thickness of the actuating plate member 211 is greater than that of the valve body plate member 223. The actuating plate member 211 has a plurality of actuating through holes 211a, and the number, position, and aperture of the actuating through holes 211a correspond to those of the valve plate through holes 223a. In this embodiment, the actuating plate member 211 is a metal plate, and the aperture of the actuating through holes 211a is the same as that of the valve plate through holes 223a. The air inlet plate 2131 has a plurality of air inlet holes 2131a, and the air inlet holes 2131a are tapered to improve the air inlet efficiency and prevent backflow of the gas. In addition, the arrangement shape of the air inlet holes 2131a can be rectangular, square, circular, or the like. The piezoelectric element 2132 is square, and is arranged on the actuating area 2131b of the air inlet plate 2131. The piezoelectric element 2132 corresponds to the actuating area 2131b of the air inlet plate 2131. In this embodiment, when the air inlet holes 2131a are arranged in a square shape, the actuating area 2131b is defined as a square, and the piezoelectric element 2132 is also square. As described above, the arrangement shape of the air inlet holes 2131a can be rectangular, square, circular, or the like. The actuating area 2131b changes its shape according to the arrangement of the air inlet holes 2131a, and the piezoelectric element 2132 also changes its shape accordingly.

[0075] As shown in FIG. 3A to FIG. 3C and FIG. 4 As shown in the above, the piezoelectric element 2132, the air inlet plate 2131, and the actuating plate member 211 are stacked and fixed to the frame 212, and an air inlet chamber 212a is formed between the actuating assembly 213, the frame 212, and the actuating plate member 211. The valve plate through holes 223a of the valve body plate member 223 and the actuating through holes 211a of the actuating plate member 211 are located below the vertical projection area of the actuating area 2131b of the air inlet plate 2131 and correspond to the actuating area 2131b vertically, as shown in the above. FIG. 3B As shown in the above, after the piezoelectric element 2132 receives the driving signal, it starts to deform and drives the air inlet plate 2131 to bend upwards. At this time, the volume of the air inlet chamber 212a increases and forms a negative pressure, which attracts the valve piece 222 upwards and closes the valve plate through holes 223a of the valve body plate member 223. At this time, as shown in the above, the air inlet holes 2131a of the air inlet plate 2131 are closed, and the air outlet hole 221a of the air outlet plate 221 is also closed.FIG. 4 As shown, the gas on the intake end 11a side of the base 11 is sucked into the actuating assembly 213 of the first actuating unit 2a, and enters the intake chamber 212a; please also refer to FIG. 3C As shown, the piezoelectric element 2132 receives the driving signal and generates deformation, which drives the intake plate 2131 to bend downward, compresses the intake chamber 212a, and pushes the gas inside the intake chamber 212a to transmit downward through the actuating through hole 211a of the actuating plate member 211 and the valve plate through hole 223a of the valve body plate member 223, so that the kinetic energy is transmitted downward from the actuating assembly 213 to the interval G, and the kinetic energy pushes the valve piece 222 to displace, so that the valve piece 222 is separated from the valve plate through hole 223a and abuts against the exhaust plate 221, thereby opening the flow path and transmitting the gas downward through the valve hole 222a to the exhaust hole 221a of the exhaust plate 221, and then introducing the gas into the first partition accommodation groove 13a through the exhaust hole 221a, and then entering the second partition accommodation groove 13b through the interval passage 16. Similarly, the piezoelectric element 2132 of the actuating assembly 213 of the second actuating unit 2b receives the driving signal and starts to generate deformation, and similarly transmits the actuation, so that the gas in the second partition accommodation groove 13b is sucked into the actuating assembly 213 of the second actuating unit 2b, enters the intake chamber 212a, and then transmits the gas downward through the valve hole 222a to the exhaust hole 221a of the exhaust plate 221, and then introduces the gas into the third partition accommodation groove 13c through the exhaust hole 221a and the interval passage 16. Finally, the piezoelectric element 2132 of the actuating assembly 213 of the third actuating unit 2c receives the driving signal and starts to generate deformation, and similarly transmits the actuation, so that the gas in the third partition accommodation groove 13c is sucked into the actuating assembly 213 of the third actuating unit 2c, enters the intake chamber 212a, and then transmits the gas downward through the valve hole 222a to the exhaust hole 221a of the exhaust plate 221, and then introduces the gas into the third partition accommodation groove 13c through the exhaust hole 221a and the interval passage 16. Thus, the gas is transmitted and pressurized through the series architecture of the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c, and each actuating unit is designed with an actuating body 21 and a valve body 22, which can prevent backflow and generate one-way airflow with large flow control effect, thereby forming a gas transmission device with output pressure of 250㎜Hg~450㎜Hg, gas flow of 1L / min~3.5L / min, high output pressure, large gas flow, and low noise.

[0076] In addition, in the specific embodiments of the present case, the valve body 22 composed of the air outlet plate 221, the valve sheet 222, and the valve body plate 223 is designed to consider the valve sheet 222 as a flexible thin film with a thickness of about 0.4-0.6 microns (μm), and the distance G between the valve sheet 222 and the recess 221b of the air outlet plate 221 is about 40-70 microns (μm). Therefore, when the piezoelectric element 2132 of the actuating assembly 213 is maintained at an operating frequency of 20-22 kHz, preferably at an operating frequency of 21 kHz, and the pressure difference is maintained at an oscillation wavelength of 30 microns (μm), the valve sheet 222 with a thickness of 3 microns (μm) is arranged in the recess 221b of the air outlet plate 221 to maintain the distance G in the range of 40-70 microns (μm). The one-way flow of the sparse and dense waves in the distance G can prevent backflow and achieve the best effect of one-way flow. Thus, the maximum flow can be obtained, and the pressure drop caused by the air flowing through the valve body 22 is minimized, which is important for maximizing the valve performance.

[0077] As can be seen from the above description, the gas transmission device emits a driving signal (driving voltage and driving frequency) through an external driving circuit, and transmits the driving signal to the first actuating unit 2a, the second actuating unit 2b, and the third actuating unit 2c through multiple sets of two wires to drive and operate. Of course, in another embodiment, the driving circuit can be arranged in the accommodating groove 13 and electrically connected to the multiple actuating units for control and driving in separate independent integrated packaging. Alternatively, in another embodiment, the driving circuit can be arranged in the accommodating groove 13 and electrically connected to the multiple actuating units for control and driving in system integrated packaging (SIP packaging).

[0078] In summary, the gas transmission device provided in the present case is composed of the air outlet plate, the valve sheet, the valve body plate, and the square-shaped actuating assembly arranged in sequence to form an actuating unit. When the piezoelectric element of the actuating assembly drives the air inlet plate, it can quickly transmit the gas downward. The misalignment between the valve plate through hole and the valve hole can prevent backflow, and the structure with large flow and backflow prevention can make the valve body act as an open flow path when the air flow is positive and as a closed flow path when the air flow is negative, thereby preventing backflow and generating one-way air flow to improve the gas transmission amount and greatly increase the gas flow. In addition, the structure design of the multiple actuating units in series can form a gas transmission device with high output pressure, large gas flow, and low noise, which is very useful in industry.

[0079] The present case can be modified by those skilled in the art, but it should not deviate from the scope of the appended patent application.
