Description

氣體檢測裝置Gas detection device

本案關於一種氣體檢測裝置,尤指一種透過一氣體傳輸致動器進行導氣之氣體檢測裝置。The present invention relates to a gas detecting device, and more particularly to a gas detecting device for conducting gas through a gas transfer actuator.

近年來,我國與鄰近區域的空氣汙染問題漸趨嚴重,尤其是細懸浮微粒(PM2.5及PM10)之濃度數據常常過高,空氣懸浮微粒濃度之監測漸受重視。但由於空氣會隨風向、風量的改變而流動,目前檢測懸浮微粒的空氣品質監測站大都為定點,所以根本無法確認當下周遭的懸浮微粒濃度,因此需要一個微型方便攜帶的氣體微粒偵測裝置來供使用者可無時無刻、隨時隨地地檢測周遭環境的懸浮微粒濃度。In recent years, the air pollution problem in China and its neighboring areas has become more and more serious. Especially the concentration data of fine aerosols (PM2.5 and PM10) are often too high, and the monitoring of airborne particle concentration has been paid more and more attention. However, since the air will flow with the change of wind direction and air volume, the air quality monitoring stations for detecting suspended particles are mostly fixed points, so it is impossible to confirm the concentration of suspended particles in the current surroundings, so a micro-friendly portable gas particle detecting device is needed. The user can detect the concentration of suspended particles in the surrounding environment anytime, anywhere.

此外,目前的氣體微粒偵測裝置往往僅能夠對單一氣體作檢測,但除了懸浮微粒之外,日常生活中尚有許多對人體有害的氣體,若是無法即時檢測,也會對人體的健康造成影響。In addition, current gas particle detection devices are often only capable of detecting a single gas, but in addition to aerosols, there are many harmful gases in daily life. If it is not detected immediately, it will also affect the health of the human body. .

此外,使用者會因為不同的場所,如工廠、辦公室、住家等會擁有不同的氣體偵測需求,如工廠需要揮發性或是會造成吸入性傷害等有毒氣體的氣體感測器,住家、辦公室則是一氧化碳、二氧化碳、溫度、濕度等感測器,但目前市售之氣體檢測裝置皆為一體式的氣體檢測裝置,其偵測之氣體已於出廠前便已經決定,無法依據使用者需求自行更改,造成氣體檢測裝置會檢測使用者需求外的氣體或是無法偵測使用者所需求的氣體,十分不便,並且使用者也難以挑選適合的氣體檢測裝置。有鑑於此,如何發展一種可依據氣體偵測需求進行感測的氣體檢測裝置實為當前極為重要的課題。In addition, users will have different gas detection requirements for different places, such as factories, offices, homes, etc., such as gas sensors that require volatility or toxic gases that cause inhalation damage, homes, offices. It is a sensor for carbon monoxide, carbon dioxide, temperature, humidity, etc., but the gas detection devices currently on the market are all integrated gas detection devices, and the detected gas has been determined before leaving the factory, and cannot be customized according to user requirements. The change causes the gas detecting device to detect the gas outside the user's demand or to detect the gas required by the user, which is very inconvenient, and it is difficult for the user to select a suitable gas detecting device. In view of this, how to develop a gas detecting device that can be sensed according to gas detection requirements is currently an extremely important issue.

本案之主要目的係提供一種氣體檢測裝置,能夠檢測空氣中所含有懸浮微粒之濃度及其他氣體之濃度,提供使用者即時且準確的氣體資訊。其中,用以檢測空氣之感測器為外接式感測器,可供使用者依需求自行搭配並且可輕易更換,增加便利性。The main purpose of the present invention is to provide a gas detecting device capable of detecting the concentration of suspended particles contained in the air and the concentration of other gases, and providing the user with instant and accurate gas information. Among them, the sensor for detecting air is an external sensor, which can be easily matched by the user according to the needs and can be easily replaced, thereby increasing convenience.

請同時參閱第3A圖、第3B圖及第4A圖,在本案實施例中,氣體傳輸致動器3係一壓電泵,包括一進氣板31、一共振片32、一壓電致動器33、一第一絕緣片34、一導電片35以及一第二絕緣片36。進氣板31、共振片32、壓電致動器33、第一絕緣片34、導電片35以及第二絕緣片36是依序堆疊組合。Please refer to FIG. 3A, FIG. 3B and FIG. 4A simultaneously. In the embodiment of the present invention, the gas transmission actuator 3 is a piezoelectric pump including an air inlet plate 31, a resonant plate 32, and a piezoelectric actuator. The device 33 has a first insulating sheet 34, a conductive sheet 35 and a second insulating sheet 36. The air intake plate 31, the resonance plate 32, the piezoelectric actuator 33, the first insulating sheet 34, the conductive sheet 35, and the second insulating sheet 36 are stacked in sequence.

在本案實施例中,進氣板31具有至少一進氣孔31a、至少一匯流排槽31b以及一匯流腔室31c。至少一匯流排槽31b是對應至少一進氣孔31a而設置。進氣孔31a供導入氣體,匯流排槽31b引導自進氣孔31a導入之氣體至匯流腔室31c。共振片32具有一中央孔32a以及一可動部32b。中央孔32a對應於進氣板31之匯流腔室31c而設置。可動部32b圍繞中央孔32a而設置。共振片32與壓電致動器33之間形成一腔室空間37。因此,當壓電致動器33被驅動時,氣體會由進氣板31的至少一進氣孔31a導入,再經至少一匯流排槽31b匯集至匯流腔室31c。接著,氣體再通過共振片32的中央孔32a,使得壓電致動器33與共振片32的可動部32b產生共振以傳輸氣體。In the embodiment of the present invention, the air inlet plate 31 has at least one air inlet hole 31a, at least one bus bar groove 31b, and a confluence chamber 31c. At least one bus bar groove 31b is provided corresponding to at least one air intake hole 31a. The intake hole 31a is for introducing a gas, and the bus bar 31b guides the gas introduced from the intake hole 31a to the confluence chamber 31c. The resonator piece 32 has a center hole 32a and a movable portion 32b. The center hole 32a is provided corresponding to the confluence chamber 31c of the air intake plate 31. The movable portion 32b is provided around the central hole 32a. A chamber space 37 is formed between the resonator piece 32 and the piezoelectric actuator 33. Therefore, when the piezoelectric actuator 33 is driven, the gas is introduced from at least one intake hole 31a of the air intake plate 31, and is collected to the confluence chamber 31c via at least one bus bar groove 31b. Then, the gas passes through the center hole 32a of the resonator piece 32, so that the piezoelectric actuator 33 resonates with the movable portion 32b of the resonance piece 32 to transport the gas.

請續參閱第3A圖、第3B圖及第4A圖,壓電致動器33包括一懸浮板33a、一外框33b、至少一支架33c以及一壓電元件33d。在本案實施例中,懸浮板33a具有一正方形形態,並可彎曲震動,但不以此為限。懸浮板33a具有一凸部33f。在本案實施例中,懸浮板33a之所以採用正方形形態設計,乃由於相較於圓形的形態,正方形懸浮板33a之結構明顯具有省電之優勢。在共振頻率下操作之電容性負載,其消耗功率會隨共振頻率之上升而增加,因正方形懸浮板33a之共振頻率較圓形懸浮板低,故所消耗的功率亦會較低。然而,在其他實施例中,懸浮板的33a形態可依實際需求而變化。外框33b環繞設置於懸浮板33a之外側。至少一支架33c連接於懸浮板33a以及外框33b之間,以提供彈性支撐懸浮板33a的支撐力。壓電元件33d具有一邊長,其小於或等於懸浮板33a之一邊長。且壓電元件33d貼附於懸浮板33a之一表面上,用以施加驅動電壓以驅動懸浮板33a彎曲振動。懸浮板33a、外框33b與至少一支架33c之間形成至少一間隙33e,用以供氣體通過。凸部33f凸設於懸浮板33a之另一表面上。在本案實施例中,懸浮片33a與凸部33f為利用一蝕刻製程製出的一體成型結構,但不以此為限。Referring to FIGS. 3A, 3B, and 4A, the piezoelectric actuator 33 includes a suspension plate 33a, an outer frame 33b, at least one bracket 33c, and a piezoelectric element 33d. In the embodiment of the present invention, the suspension plate 33a has a square shape and can be flexed and shaken, but not limited thereto. The suspension plate 33a has a convex portion 33f. In the embodiment of the present invention, the suspension plate 33a is designed in a square shape because the structure of the square suspension plate 33a obviously has the advantage of power saving compared to the circular shape. The capacitive load operating at the resonant frequency increases its power consumption as the resonant frequency increases. Since the resonant frequency of the square suspension plate 33a is lower than that of the circular suspension plate, the power consumed is also low. However, in other embodiments, the shape of the suspension plate 33a may vary depending on actual needs. The outer frame 33b is circumferentially disposed on the outer side of the suspension plate 33a. At least one bracket 33c is coupled between the suspension plate 33a and the outer frame 33b to provide a supporting force for elastically supporting the suspension plate 33a. The piezoelectric element 33d has a side length which is less than or equal to one side length of the suspension plate 33a. And the piezoelectric element 33d is attached to one surface of the suspension plate 33a for applying a driving voltage to drive the suspension plate 33a to bend and vibrate. At least one gap 33e is formed between the suspension plate 33a, the outer frame 33b and the at least one bracket 33c for gas to pass therethrough. The convex portion 33f is protruded from the other surface of the suspension plate 33a. In the embodiment of the present invention, the suspension piece 33a and the convex portion 33f are integrally formed by an etching process, but are not limited thereto.

請參閱第4A圖,在本案實施例中,腔室空間37可利用在共振片32及壓電致動器33之外框33b之間所產生的間隙填充一材質,例如導電膠,但不以此為限,使得共振片32與懸浮板33a之間可維持一定的深度,進而可導引氣體更迅速地流動。此外,因懸浮板33a與共振片32保持適當距離,使彼此的接觸干涉減少,噪音的產生也可被降低。在其他實施例中,可藉由增加壓電致動器33的外框33b的高度來減少填充在共振片32及壓電致動器33之外框33b之間的間隙之中的導電膠厚度。如此,在仍可使得懸浮板33a與共振片32保持適當距離的情況下,氣體傳輸致動器3的整體組裝不會因熱壓溫度及冷卻溫度而影響所填充導電膠之厚度,可避免導電膠因熱脹冷縮因素影響到腔室空間37在組裝完成後的實際大小。在其他實施例中,懸浮板33a可以採以沖壓方式成形,使懸浮板33a的凸部33f遠離壓電元件33d的一表面,與外框33b的遠離壓電元件33d的一表面形成非共平面,亦即凸部33f遠離壓電元件33d的表面將低於外框33b遠離壓電元件33d的表面。利用外框33b遠離壓電元件33d的表面上塗佈少量填充材質,例如:導電膠,以熱壓方式使壓電致動器33貼合於共振片32,進而使得壓電致動器33得以與共振片32組配結合。藉由將壓電致動器33之懸浮板33a採以沖壓方式成形,以構成腔室空間37的結構改良,腔室空間37得以透過調整壓電致動器33之懸浮板33a沖壓成形距離來完成,有效地簡化了調整腔室空間37的結構設計步驟。同時也達成簡化製程,縮短製程時間等優點。在本案實施例中,第一絕緣片34、導電片35及第二絕緣片36皆為框型的薄型片體,但不以此為限。Referring to FIG. 4A, in the embodiment of the present invention, the chamber space 37 can be filled with a material, such as a conductive paste, by using a gap generated between the resonator piece 32 and the frame 33b outside the piezoelectric actuator 33, but not This is limited to maintain a certain depth between the resonant plate 32 and the suspension plate 33a, thereby guiding the gas to flow more rapidly. Further, since the suspension plate 33a and the resonance piece 32 are kept at an appropriate distance, contact interference with each other is reduced, and generation of noise can also be reduced. In other embodiments, the thickness of the conductive paste filled in the gap between the resonator piece 32 and the frame 33b outside the piezoelectric actuator 33 can be reduced by increasing the height of the outer frame 33b of the piezoelectric actuator 33. . Thus, in the case where the suspension plate 33a and the resonance plate 32 can still be kept at an appropriate distance, the overall assembly of the gas transmission actuator 3 does not affect the thickness of the filled conductive rubber due to the hot pressing temperature and the cooling temperature, and the conduction can be avoided. The glue affects the actual size of the chamber space 37 after assembly is completed due to thermal expansion and contraction factors. In other embodiments, the suspension plate 33a may be formed by stamping such that the convex portion 33f of the suspension plate 33a is away from a surface of the piezoelectric element 33d and forms a non-coplanar with a surface of the outer frame 33b remote from the piezoelectric element 33d. That is, the surface of the convex portion 33f away from the piezoelectric element 33d will be lower than the surface of the outer frame 33b away from the piezoelectric element 33d. A small amount of filling material, such as a conductive paste, is applied to the surface of the outer frame 33b away from the piezoelectric element 33d, and the piezoelectric actuator 33 is attached to the resonant plate 32 by heat pressing, thereby enabling the piezoelectric actuator 33 to be It is combined with the resonator piece 32. By forming the suspension plate 33a of the piezoelectric actuator 33 in a press form, the structure of the chamber space 37 is improved, and the chamber space 37 is adjusted by the adjustment of the suspension plate 33a of the piezoelectric actuator 33. This completes the structural design steps of the adjustment chamber space 37. At the same time, it also achieves the advantages of simplifying the process and shortening the process time. In the embodiment of the present invention, the first insulating sheet 34, the conductive sheet 35 and the second insulating sheet 36 are all thin frame-shaped sheets, but are not limited thereto.

請續參閱第3A圖、第3B圖及第4A圖,進氣板31、共振片32、壓電致動器33、第一絕緣片34、導電片35以及第二絕緣片36皆可透過微機電的面型微加工技術製程,使氣體傳輸致動器3的體積縮小,以構成一微機電系統之氣體傳輸致動器3。Referring to FIGS. 3A, 3B, and 4A, the air intake plate 31, the resonant plate 32, the piezoelectric actuator 33, the first insulating sheet 34, the conductive sheet 35, and the second insulating sheet 36 are all transparent. The electromechanical surface micromachining process reduces the volume of the gas delivery actuator 3 to form a gas transmission actuator 3 of a microelectromechanical system.

請參閱第4B圖,在壓電致動器33作動流程中,壓電致動器33的壓電元件33d被施加驅動電壓後產生形變,帶動懸浮板33a向遠離進氣板31的方向位移,此時腔室空間37的容積提升,於腔室空間37內形成了負壓,便汲取匯流腔室31c內的氣體進入腔室空間37內。同時,共振片32產生共振同步向遠離進氣板31的方向位移,連帶增加了匯流腔室31c的容積。且因匯流腔室31c內的氣體進入腔室空間37的關係,造成匯流腔室31c內同樣為負壓狀態,進而通過進氣口31a以及匯流排槽31b來吸取氣體進入匯流腔室31c內。Referring to FIG. 4B, in the operation of the piezoelectric actuator 33, the piezoelectric element 33d of the piezoelectric actuator 33 is deformed by applying a driving voltage, and the suspension plate 33a is displaced in a direction away from the air inlet plate 31. At this time, the volume of the chamber space 37 is increased, and a negative pressure is formed in the chamber space 37, and the gas in the confluence chamber 31c is taken into the chamber space 37. At the same time, the resonance piece 32 generates resonance resonance displacement in a direction away from the air intake plate 31, which increases the volume of the confluence chamber 31c. Due to the relationship between the gas in the confluence chamber 31c entering the chamber space 37, the confluence chamber 31c is also in a negative pressure state, and the gas is sucked into the confluence chamber 31c through the inlet port 31a and the bus bar groove 31b.

接著,如第4C圖所示,壓電元件33d帶動懸浮板33a朝向進氣板31位移,壓縮腔室空間37,同樣的,共振片32被懸浮板33a致動產生共振而朝向進氣板31位移,迫使同步推擠腔室空間37內的氣體通過間隙33e進一步傳輸,以達到傳輸氣體的效果。Next, as shown in FIG. 4C, the piezoelectric element 33d drives the suspension plate 33a toward the air intake plate 31 to compress the chamber space 37.
