Description

霧化給藥裝置之鎖定結構Locking structure of atomized drug delivery device

本發明係關於一種鎖定結構，尤其指一種霧化給藥裝置之鎖定結構。The invention relates to a locking structure, in particular to a locking structure of an atomized drug delivery device.

霧化給藥裝置是指以噴霧形式來提供使用者特定治療用途的產品。舉例來說，氣喘症患者的隨身吸入劑瓶即為一種典型的霧化給藥裝置。Nebulized drug delivery devices refer to products that provide users with specific therapeutic uses in the form of sprays. For example, a portable inhaler bottle for asthma patients is a typical nebulized drug delivery device.

基於產品的特殊性，必須確保霧化給藥裝置在每次使用時皆釋出相同的劑量，且當療程即將結束（即藥劑消耗至一定量）時，也需要配置鎖定機構來提醒使用者及時更換。Due to the particularity of the product, it must be ensured that the nebulized drug delivery device releases the same dose every time it is used, and when the course of treatment is about to end (ie, the medicine is consumed to a certain amount), a locking mechanism needs to be configured to remind the user in time replace.

現有的一種霧化給藥裝置之鎖定結構採用彈片與推桿的兩件式組合。在操作霧化給藥裝置同時，推桿逐步地靠近被預壓之彈片，最終推抵彈片復位而觸發鎖定機構。The locking structure of an existing atomized drug delivery device uses a two-piece combination of an elastic sheet and a push rod. While operating the atomized drug delivery device, the push rod gradually approached the preloaded shrapnel, and finally pushed against the shrapnel to reset and trigger the locking mechanism.

然而，上述鎖定機構存在若干缺點：首先為霧化給藥裝置的外殼需設置預壓部位，特殊的形狀要求致使外殼脫模困難，彈片在組裝同時也需保持對齊預壓位置，製造成本與結構複雜性較高。此外，由於被預壓的彈片必須可被推動，無法固設於凹槽內，故彈片可能因產品掉落、使用中的金屬共振現象而意外回彈，使霧化給藥裝置被錯誤地鎖定。However, the above locking mechanism has several shortcomings: first, a pre-pressing part needs to be provided for the casing of the atomized drug delivery device, the special shape requirements make it difficult to demold the casing, and the shrapnel needs to maintain the pre-compression position while assembling, manufacturing cost and structure The complexity is higher. In addition, because the pre-loaded shrapnel must be able to be pushed and cannot be fixed in the groove, the shrapnel may rebound unexpectedly due to the product falling and the metal resonance phenomenon in use, causing the atomized drug delivery device to be erroneously locked .

為解決現有技術的問題，本發明的目的為提出一種霧化給藥裝置之鎖定結構，其降低結構複雜性與製造成本較低，且可防止霧化給藥裝置被錯誤地鎖定。In order to solve the problems of the prior art, the object of the present invention is to propose a locking structure for an atomized drug delivery device, which reduces the structural complexity and the manufacturing cost, and prevents the atomized drug delivery device from being erroneously locked.

根據本發明之一實施方式，霧化給藥裝置之鎖定結構包含第一殼體、第二殼體、螺桿以及扣件。第一殼體具有至少一個抵掣部與至少一個扣槽，且扣槽鄰接並形成於抵掣部的一側。第二殼體可旋轉地連接第一殼體，藉而能相對第一殼體沿一旋轉軸線旋轉。螺桿樞設於第二殼體並平行於前述旋轉軸線，且螺桿隨第二殼體與第一殼體的相對旋轉而沿螺桿之中心軸旋轉。扣件連接螺桿而受其驅動，且扣件朝向第一殼體之抵掣部凸伸。扣件包含扣接部，扣接部供抵掣部抵掣以產生位移。扣接部之形狀與扣槽匹配，以於通過抵掣部後而限位於扣槽。According to one embodiment of the present invention, the locking structure of the atomized drug delivery device includes a first housing, a second housing, a screw and a fastener. The first housing has at least one blocking portion and at least one buckling groove, and the buckling groove is adjacent to and formed on one side of the blocking portion. The second housing is rotatably connected to the first housing, so that it can rotate relative to the first housing along a rotation axis. The screw is pivotally arranged on the second housing and parallel to the aforementioned rotation axis, and the screw rotates along the central axis of the screw with the relative rotation of the second housing and the first housing. The fastener is connected to and driven by the screw, and the fastener protrudes toward the abutment portion of the first housing. The buckle includes a buckling portion, and the buckling portion is provided for the abutment portion to abut the abutment portion to generate displacement. The shape of the buckling portion matches with the buckling groove so as to be limited to the buckling groove after passing through the catching portion.

在一實施例中，前述抵掣部可具有抵接側以及限位側，抵接側以及限位側位於抵掣部之相對側。當扣接部接觸抵接側時，抵掣部導引扣接部自抵接側移至限位側。In an embodiment, the abutment portion may have an abutting side and a limiting side, and the abutting side and the limiting side are located on opposite sides of the abutting portion. When the buckling portion contacts the abutting side, the abutment portion guides the buckling portion to move from the abutting side to the limiting side.

在一實施例中，前述抵掣部朝向旋轉軸線凸伸，於扣接部接觸抵接側時，扣接部朝向旋轉軸線位移後再復位於限位側而限位於扣槽。In one embodiment, the abutment portion protrudes toward the rotation axis. When the buckle portion contacts the abutment side, the buckle portion is displaced toward the rotation axis and then resets to the limiting side to be limited to the buckle groove.

在一實施例中，抵掣部以及扣槽也可以是兩組以上。舉例來說，第一殼體可相對旋轉軸線對稱設置另一組抵掣部以及扣槽。另外，依據不同的定位需求，抵掣部與扣槽也可以為三組以上，並且等距地分布於第一殼體。In an embodiment, there may be more than two sets of the locking portion and the buckle groove. For example, the first housing may be symmetrically arranged with respect to the rotation axis to provide another set of abutment portions and buckle grooves. In addition, according to different positioning requirements, the contact portion and the buckle groove may be more than three groups, and are equally distributed in the first housing.

前述的扣接部可以一體成形於扣件，例如扣件可以為塑膠、金屬等材料之整體成形。或者，扣接部與扣件也可以組合連接為一個整體，並且互為相異的材料。The aforementioned fastening portion may be integrally formed on the fastener, for example, the fastener may be integrally formed of plastic, metal and other materials. Alternatively, the fastening portion and the fastener may be combined and connected as a whole, and the materials are different from each other.

在一實施例中，扣件更包含一連接部及一連接臂。連接部具有螺紋孔，螺桿與螺紋孔相嚙合，使扣件連接螺桿並受螺桿驅動。連接臂的一端設於連接部，扣接部設置於連接臂的另一端。連接臂可為一金屬彈片且嵌設於連接部。In one embodiment, the fastener further includes a connecting portion and a connecting arm. The connecting part has a screw hole, and the screw is engaged with the screw hole, so that the fastener is connected to the screw and driven by the screw. One end of the connecting arm is provided at the connecting portion, and the fastening portion is provided at the other end of the connecting arm. The connecting arm may be a metal dome and embedded in the connecting portion.

在一實施例中，扣槽可以貫穿地設置於第一殼體、或是設置在第一殼體之內表面。在此實施例中，扣槽限位扣接部之兩端所夾的圓心角小於等於25度。In an embodiment, the buckle groove may be disposed through the first casing or on the inner surface of the first casing. In this embodiment, the center angle between the two ends of the buckle slot limiting buckle is less than or equal to 25 degrees.

在一實施例中，於一初始狀態下，扣接部與旋轉軸線的距離大於第二殼體之外表面與旋轉軸線的距離。In an embodiment, in an initial state, the distance between the fastening portion and the rotation axis is greater than the distance between the outer surface of the second housing and the rotation axis.

在其他實施例中，扣槽也可以設置於第一殼體的外部(例如外表面或是凸出地設置)。在此實施例中，第二殼體之外表面可設有擋塊。在扣接部及扣槽彼此限位時，前述第一殼體之內表面可以凸設至少一個施力部，施力部的位置與螺桿之一端相對應。第一殼體與第二殼體相對旋轉時，施力部接觸螺桿，藉以推動螺桿旋轉。In other embodiments, the buckle groove may also be disposed on the outside of the first housing (for example, on the outer surface or protrudingly). In this embodiment, a stopper may be provided on the outer surface of the second housing. When the buckling portion and the buckling groove are limited to each other, at least one urging portion may be protruded on the inner surface of the first housing, and the position of the urging portion corresponds to one end of the screw. When the first housing and the second housing rotate relatively, the force applying portion contacts the screw, thereby pushing the screw to rotate.

根據本發明之另一實施方式，霧化給藥裝置之鎖定結構，包含一第一殼體，具有至少一抵掣部及至少一扣槽，該扣槽鄰接並形成於該抵掣部的一側；可旋轉地連接該第一殼體的一第二殼體；樞設於該第二殼體的一螺桿；以及連接該螺桿的一扣件，其中：當該第二殼體相對於該第一殼體沿一旋轉軸線旋轉時，該扣件受該螺桿驅動向該第一殼體的該抵掣部線性移動，當該第二殼體相對於該第一殼體持續旋轉使該扣件之一扣接部接觸該抵掣部時，該扣接部受該抵掣部抵掣而產生位移，且當該扣接部通過該抵掣部後，該扣接部復位並扣合於該扣槽，從而限制該第一殼體相對於該第二殼體沿該旋轉軸線之旋轉。According to another embodiment of the present invention, a locking structure of an aerosolized drug delivery device includes a first housing having at least one abutment portion and at least one buckle groove, the buckle groove abutting and formed on a portion of the abutment portion Side; a second casing rotatably connected to the first casing; a screw pivotally arranged in the second casing; and a fastener connected to the screw, wherein: when the second casing is opposite to the When the first housing rotates along a rotation axis, the fastener is driven by the screw to linearly move to the abutment portion of the first housing, and when the second housing continues to rotate relative to the first housing, the buckle When one of the fastening parts of the piece contacts the abutment part, the fastening part is displaced by the abutment part of the abutment part, and when the abutment part passes through the abutment part, the buckle part is reset and engaged with The buckle groove restricts the rotation of the first housing relative to the second housing along the axis of rotation.

在一實施例中，前述抵掣部具有一抵接側以及一限位側，抵接側與限位側位於抵掣部之相對側，扣槽鄰接限位側，且扣件包含：一連接部，具有一螺紋孔，螺紋孔與螺桿嚙合；及一連接臂，固定連接於連接部，且扣接部位於連接臂遠離連接部之一端。In an embodiment, the abutting portion has an abutting side and a limiting side, the abutting side and the limiting side are located on opposite sides of the abutting portion, the buckle groove abuts the limiting side, and the fastener includes: a connection The part has a threaded hole, the threaded hole meshes with the screw; and a connecting arm, which is fixedly connected to the connecting part, and the fastening part is located at one end of the connecting arm away from the connecting part.

在一實施例中，於前述扣接部受抵掣部抵掣而產生位移，連接臂因應扣接部之移動而暫時地形變直至扣接部通過抵掣部。In an embodiment, the abutment portion of the abutment portion is abutted by the abutment portion to cause displacement, and the connecting arm is temporarily deformed in response to the movement of the abutment portion until the abutment portion passes the abutment portion.

在一實施例中，前述連接臂的復位力順勢導引扣接部滑移至限位側，進而使扣接部扣合扣槽。In an embodiment, the restoring force of the aforementioned connecting arm guides the buckling portion to slide to the limit side, thereby causing the buckling portion to buckle into the buckling groove.

在一實施例中，於螺桿旋轉，扣件受到第二殼體的止擋而沿著螺桿的旋轉軸線方向線性移動。In an embodiment, when the screw rotates, the fastener is linearly moved along the direction of the rotation axis of the screw by the stop of the second housing.

在一實施例中，於一初始狀態下，扣件位於螺桿相對較遠離第一殼體的一端；且於第一殼體與第二殼體相對旋轉時，扣件受螺桿的帶動而沿著螺桿的旋轉軸線方向向第一殼體移動。In an embodiment, in an initial state, the fastener is located at an end of the screw relatively far away from the first housing; and when the first housing and the second housing rotate relatively, the fastener is driven by the screw and moves along The direction of the rotation axis of the screw moves toward the first housing.

在一實施例中，當第二殼體相對於第一殼體持續旋轉，扣接部係接觸抵掣部，並相對於抵掣部滑動並扣入扣槽。In an embodiment, when the second housing continues to rotate relative to the first housing, the buckling portion contacts the abutment portion, and slides relative to the abutment portion and buckles into the buckle groove.

在一實施例中，於扣接部固定於扣槽後，第一殼體與第二殼體的相對移動範圍受到扣槽中的扣接部的限制，從而使第二殼體無法相對第一殼體旋轉。In an embodiment, after the fastening portion is fixed in the fastening groove, the relative movement range of the first housing and the second housing is restricted by the fastening portion in the fastening groove, so that the second housing cannot be relative to the first The housing rotates.

本文件所揭露的霧化給藥裝置之鎖定結構僅需在第一殼體設置定位用的扣槽，扣件之扣接部在進入扣槽前為自由端，不採用須預壓的彈片元件，也不須在組裝同時保持對齊預壓位置，因此製造成本與結構複雜性較低，並可防止霧化給藥裝置被錯誤地鎖定。The locking structure of the atomized drug delivery device disclosed in this document only needs to be provided with a buckle groove for positioning in the first housing, and the buckle portion of the buckle is a free end before entering the buckle groove, and no preloaded shrapnel element is used It is not necessary to maintain the alignment pre-compression position during assembly, so the manufacturing cost and structural complexity are low, and the atomized drug delivery device can be prevented from being erroneously locked.

為充分瞭解本發明之目的、特徵及功效，茲藉由下述具體之實施例，並配合所附之圖式，對本發明做一詳細說明，說明如後。In order to fully understand the purpose, features and effects of the present invention, the following specific embodiments and the accompanying drawings are used to make a detailed description of the present invention and the following description.

請參照圖1，霧化給藥裝置之鎖定結構100包含第一殼體200、第二殼體300、螺桿400以及扣件500。第一殼體200與第二殼體300可旋轉地連接，使兩者可相對彼此沿著旋轉軸線A旋轉。螺桿400可樞轉地設置於第二殼體300的一側(外表面301之外側)，且螺桿400的軸向平行於旋轉軸線A。當第二殼體300相對於第一殼體200旋轉時，螺桿400隨之沿著自體之中心軸B旋轉。扣件500同樣設於第二殼體300的一側，且扣件500連接螺桿400而受其驅動。由於扣件500貼近第二殼體300之側面，當螺桿400旋轉時，扣件500受到第二殼體300止擋而無法一齊旋轉，僅能對應螺桿400旋轉而相對螺桿400上下移動。Referring to FIG. 1, the locking structure 100 of the atomized drug delivery device includes a first housing 200, a second housing 300, a screw 400 and a fastener 500. The first housing 200 and the second housing 300 are rotatably connected so that they can rotate along the rotation axis A relative to each other. The screw 400 is pivotally disposed on one side (outer side of the outer surface 301) of the second housing 300, and the axial direction of the screw 400 is parallel to the rotation axis A. When the second housing 300 rotates relative to the first housing 200, the screw 400 rotates along the central axis B of the body. The fastener 500 is also disposed on one side of the second housing 300, and the fastener 500 is connected to the screw 400 and driven by it. Since the fastener 500 is close to the side of the second housing 300, when the screw 400 rotates, the fastener 500 is stopped by the second housing 300 and cannot rotate together, and can only move up and down relative to the screw 400 in response to the rotation of the screw 400.

配合參照圖2A與圖2B，第一殼體200具有兩組抵掣部210以及扣槽220。扣槽220鄰接並形成於抵掣部210的一側。如圖2B之剖示圖所示，抵掣部210的兩側又分為抵接側211以及限位側212，且扣槽220位於限位側212。兩組抵掣部210與扣槽220係相對旋轉軸線A對稱設置。在其他實施例中，抵掣部210與扣槽220也可以為單組、或是多組且等距地分佈於第一殼體200。Referring to FIGS. 2A and 2B together, the first housing 200 has two sets of abutment portions 210 and buckle grooves 220. The buckle groove 220 is adjacent to and formed on one side of the abutment portion 210. As shown in the cross-sectional view of FIG. 2B, both sides of the abutment portion 210 are further divided into an abutment side 211 and a limiting side 212, and the buckle groove 220 is located on the limiting side 212. The two sets of blocking portions 210 and the buckle groove 220 are arranged symmetrically with respect to the rotation axis A. In other embodiments, the blocking portion 210 and the buckle groove 220 may also be a single group, or multiple groups, and are equally distributed in the first housing 200.

配合圖2A、圖2B參照圖3A，扣件500與螺桿400連接，並透過樞接於第二殼體300之螺桿400來線性移動。扣件500具有連接部510與連接臂520。連接部510具有適於與螺桿400相嚙合的螺紋孔511，使連接部510能夠受螺桿400的帶動而於螺桿400上相對於第二殼體300線性移動。連接臂520的一端設於連接部510，連接臂520在本實施例中呈扁長形，其自連接部510朝向抵掣部210凸伸。連接臂520的端部具有與扣槽220形狀匹配的扣接部521。扣件500的連接部510、連接臂520與扣接部521可以為一體成形。或者，連接部510、連接臂520與扣接部521也可透過固定連接的組合方式來結合成為扣件500。Referring to FIG. 3A in conjunction with FIGS. 2A and 2B, the fastener 500 is connected to the screw 400 and linearly moves through the screw 400 pivotally connected to the second housing 300. The fastener 500 has a connecting portion 510 and a connecting arm 520. The connecting portion 510 has a screw hole 511 suitable for meshing with the screw 400, so that the connecting portion 510 can be driven by the screw 400 to move linearly on the screw 400 relative to the second housing 300. One end of the connecting arm 520 is provided in the connecting portion 510. In this embodiment, the connecting arm 520 is elongated and protrudes from the connecting portion 510 toward the abutment portion 210. The connecting arm 520 has an engaging portion 521 matching the shape of the engaging groove 220 at the end. The connecting portion 510, the connecting arm 520 and the fastening portion 521 of the fastener 500 may be integrally formed. Alternatively, the connecting portion 510, the connecting arm 520, and the fastening portion 521 can also be combined into the fastener 500 through a combination of fixed connection.

參照圖3B，為清楚顯示扣件500、螺桿400之移動，此處省略第二殼體300。第一殼體200之內表面設置有凸出的兩個施力部230，施力部230位置對應螺桿400之一端（頂部）。而螺桿400的頂部則具有複數個驅動端410。如圖3B所示，施力部230的形狀與驅動端410相匹配，以供推動其中一個驅動端410。當第一殼體200與第二殼體300相對旋轉時，施力部230接觸而推動驅動端410，繼而推動螺桿400旋轉。在其他實施例中，施力部230的數量可以是單個，也可以是多數個等距分布於第一殼體200。Referring to FIG. 3B, to clearly show the movement of the fastener 500 and the screw 400, the second housing 300 is omitted here. The inner surface of the first housing 200 is provided with two protruding force applying portions 230, and the position of the force applying portion 230 corresponds to one end (top) of the screw 400. The screw 400 has a plurality of driving ends 410 on the top. As shown in FIG. 3B, the shape of the urging portion 230 matches the driving end 410 for pushing one of the driving ends 410. When the first housing 200 and the second housing 300 rotate relatively, the urging portion 230 contacts and pushes the driving end 410, and then pushes the screw 400 to rotate. In other embodiments, the number of the urging portions 230 may be a single, or a plurality of equidistantly distributed on the first housing 200.

當然，驅動螺桿400以帶動扣件500線性移動的方法眾多，本實施方式僅略舉例說明，故施力部230的實施態樣可以有多種，並且這些態樣不排除於本實施方式所涵蓋的範圍。同時，扣槽220的設置位置也不限制於第一殼體200之內表面，而可以為貫穿地設置在第一殼體200。Of course, there are many methods for driving the screw 400 to drive the fastener 500 to move linearly. This embodiment is only a few examples, so the force applying portion 230 may have various implementation forms, and these aspects are not excluded from the scope of this embodiment. range. At the same time, the installation position of the buckle groove 220 is not limited to the inner surface of the first casing 200, but may be provided through the first casing 200 through.

請參照圖3C，由圖2A至圖3B可知，第二殼體300繞旋轉軸線A旋轉而帶動扣件500線性地往扣槽220移動。其後，扣接部521係接觸抵掣部210，並相對於抵掣部210滑動並扣入扣槽220。在較佳的實施例中，扣槽220可以為圖3C所示的圓弧形，且扣槽220用以限位扣接部521兩端的止擋端221所夾的圓心角C宜小於等於25度。藉此，當扣接部521抵達抵掣部210之位置時，扣槽220的寬度足以確保扣接部521正確地扣入扣槽220，同時扣槽220的寬度又保持在一定的限度內而能夠達成有效的限位扣合效果。Please refer to FIG. 3C. As can be seen from FIGS. 2A to 3B, the second housing 300 rotates around the rotation axis A to drive the fastener 500 to move linearly toward the buckle groove 220. Thereafter, the engaging portion 521 contacts the abutment portion 210 and slides with respect to the abutment portion 210 and snaps into the engaging groove 220. In a preferred embodiment, the buckle groove 220 may be a circular arc shape as shown in FIG. 3C, and the buckle groove 220 is used to limit the center angle C of the center of the stop end 221 between the two ends of the buckling portion 521 should be less than or equal to 25 degree. In this way, when the buckle portion 521 reaches the position of the catch portion 210, the width of the buckle groove 220 is sufficient to ensure that the buckle portion 521 is correctly buckled into the buckle groove 220, while the width of the buckle groove 220 is kept within a certain limit. Can achieve an effective limit buckling effect.

圖4A與圖4B示意霧化給藥裝置之鎖定結構100的操作過程。在圖4A的初始狀態下，扣件500位於螺桿400的最底部，也就是位於螺桿400相對較遠離第一殼體200的一端。在第一殼體200與第二殼體300相對旋轉的同時，扣件500及其扣接部521亦受螺桿400帶動而向上移動，也就是向著第一殼體的抵掣部210線性移動。4A and 4B illustrate the operation process of the locking structure 100 of the atomized drug delivery device. In the initial state of FIG. 4A, the fastener 500 is located at the bottom of the screw 400, that is, at the end of the screw 400 relatively away from the first housing 200. While the first housing 200 and the second housing 300 rotate relatively, the fastener 500 and its engaging portion 521 are also driven by the screw 400 to move upward, that is, linearly move toward the abutment portion 210 of the first housing.

請參照圖5A至圖5D，在圖5A中，當第二殼體300相對於第一殼體200持續旋轉使扣件500移動至設定的位置後，扣接部521開始接觸抵掣部210之抵接側211。如圖5B所示，扣件500繼續朝向第一殼體200移動時，由於抵掣部210係設置為朝向旋轉軸線A凸伸，於扣接部521接觸抵接側211時，扣接部521受抵掣部210抵掣而朝向旋轉軸線A產生位移，連接臂520因應扣接部521之移動而暫時地形變直至扣接部521通過抵掣部210。Please refer to FIGS. 5A to 5D. In FIG. 5A, when the second housing 300 continues to rotate relative to the first housing 200 to move the fastener 500 to the set position, the fastening portion 521 starts to contact the stop portion 210 Borne side 211. As shown in FIG. 5B, when the fastener 500 continues to move toward the first housing 200, since the abutment portion 210 is configured to protrude toward the rotation axis A, when the abutment portion 521 contacts the abutment side 211, the abutment portion 521 The resisting portion 210 resists and generates displacement toward the rotation axis A. The connecting arm 520 temporarily deforms in response to the movement of the catching portion 521 until the catching portion 521 passes the catching portion 210.

參照圖5C，當扣件500之扣接部521通過抵掣部210時，連接臂520的復位力順勢導引扣接部521滑移至限位側212，進而使扣接部521限位於扣槽220。Referring to FIG. 5C, when the buckling portion 521 of the fastener 500 passes through the catch portion 210, the reset force of the connecting arm 520 guides the buckling portion 521 to slide to the limiting side 212, thereby limiting the buckling portion 521 to the buckle槽220。 The slot 220.

參照圖5D，在扣接部521固定於扣槽220後，第一殼體200與第二殼體300的相對移動受到扣槽220中的扣接部521的限制，故第二殼體300無法自由地相對第一殼體200旋轉，形成對霧化給藥裝置的鎖定效果。Referring to FIG. 5D, after the fastening portion 521 is fixed to the fastening groove 220, the relative movement of the first housing 200 and the second housing 300 is restricted by the fastening portion 521 in the fastening groove 220, so the second housing 300 cannot Rotate relative to the first housing 200 freely to form a locking effect on the atomized drug delivery device.

參照圖6，圖6中示出霧化給藥裝置之鎖定結構100的另一種扣件500’，其可選擇地替代圖1、圖3A、圖3B、圖4A~圖5D所示的扣件500。類似地，扣件500’與螺桿400連接，並透過樞接於第二殼體300之螺桿400來線性移動。扣件500’具有連接部510’與連接臂520’。連接部510’具有適於與螺桿400相嚙合的螺紋孔511’，使連接部510’能夠受螺桿400的帶動而於螺桿400上相對於第二殼體300線性移動。Referring to FIG. 6, another fastener 500' of the locking structure 100 of the atomized drug delivery device is shown in FIG. 6, which can optionally replace the fastener shown in FIGS. 1, 3A, 3B, 4A-5D 500. Similarly, the fastener 500' is connected to the screw 400 and linearly moves through the screw 400 pivotally connected to the second housing 300. The fastener 500' has a connecting portion 510' and a connecting arm 520'. The connecting portion 510' has a screw hole 511' suitable for engaging with the screw 400, so that the connecting portion 510' can be driven by the screw 400 to linearly move on the screw 400 relative to the second housing 300.

在本實施例中，連接臂520’與扣接部521’可為一（略呈V形的）金屬彈片。此（略呈V形的）金屬彈片的一部份為連接臂520’，連接臂520’的一端嵌設於連接部510’。扣接部521’則位於此V形金屬彈片的另一部分（即連接臂520’相對於嵌設在連接部510’的另一端），其形狀可與扣槽220匹配，且其傾斜的角度被設計為適於通過抵掣部210，頂抵抵掣部210達到鎖固第一殼體200與第二殼體300。扣件500’的移動方式類似於扣件500的移動方式，可參照圖3B、圖4A~圖5D的示意圖，在此不多加贅述。In this embodiment, the connecting arm 520' and the fastening portion 521' may be a (slightly V-shaped) metal dome. A part of this (slightly V-shaped) metal dome is a connecting arm 520', and one end of the connecting arm 520' is embedded in the connecting portion 510'. The buckle portion 521' is located at another part of the V-shaped metal dome (that is, the connecting arm 520' is opposite to the other end embedded in the connecting portion 510'), and its shape can match the buckle groove 220, and its inclined angle is The design is suitable for locking the first housing 200 and the second housing 300 through the abutting portion 210 and the abutting abutting portion 210. The movement method of the fastener 500' is similar to the movement method of the fastener 500, and reference may be made to the schematic diagrams of FIG. 3B and FIG. 4A to FIG. 5D, which will not be repeated here.

在本實施例中，由於連接臂520’與扣接部521’採用金屬材質，可使扣接部521’固定於扣槽220後可承受更大的扭力。In this embodiment, since the connecting arm 520' and the buckle portion 521' are made of metal, the buckle portion 521' can be fixed in the buckle groove 220 and can withstand greater torsion.

要注意的是，本發明之扣槽220的形狀並未限定於圖式所呈現的態樣，可依據實際需求（例如搭配扣件500之扣接部521或扣件500’之扣接部521’）進行調整。It should be noted that the shape of the buckle groove 220 of the present invention is not limited to what is shown in the drawings, and can be based on actual needs (for example, with the buckle portion 521 of the buckle 500 or the buckle portion 521 of the buckle 500' ') Make adjustments.

再參照圖7A以及圖7B，除了前述設置外，扣槽220也可以設置於第一殼體200外部，扣件500之連接臂520、扣接部521則依據扣槽220的方向與形狀變化。為了進一步增加扣合力，第二殼體300之外表面301可以設置擋塊310，在扣接部521扣合於扣槽220而彼此限位時，扣件500被限位於擋塊310及扣槽220之間，以防止扣接部521脫落。本實施例有關於連接臂520以及扣接部521在扣合過程中的作動關係如同圖5A至圖5D之段落說明，故此處不再重述。Referring again to FIGS. 7A and 7B, in addition to the foregoing configuration, the buckle groove 220 may also be provided outside the first housing 200, and the connecting arm 520 and the buckle portion 521 of the fastener 500 change according to the direction and shape of the buckle groove 220. In order to further increase the buckling force, the outer surface 301 of the second housing 300 may be provided with a stopper 310. When the buckle portion 521 is locked to the buckle groove 220 to limit each other, the fastener 500 is restricted to the stopper 310 and the buckle groove Between 220 to prevent the buckling portion 521 from falling off. This embodiment relates to the operation relationship of the connecting arm 520 and the buckling portion 521 during the buckling process as described in the paragraphs of FIGS. 5A to 5D, so it will not be repeated here.

在本實施例中，在連接臂520（或連接臂520’）於初始狀態下，扣接部521（或扣接部521’）與旋轉軸線A的距離，係大於第二殼體300之外表面301與旋轉軸線A的距離。在此，扣接部521（或扣接部521’）與旋轉軸線A的距離係定義為扣接部521（或扣接部521’）上的各點與旋轉軸線A的距離的平均。換言之，扣件500及其扣接部521（或扣接部521’）獨立地安裝於第二殼體300的外表面301外部，因此只需要提供連接臂520（或連接臂520’）產生暫時形變的空間，不需要另行提供容置整個扣件500的凹槽，相較於習用鎖定結構較不會對結構形成限制。藉此，第一殼體200或第二殼體300的結構複雜性可以有效地降低。In this embodiment, when the connecting arm 520 (or the connecting arm 520') is in an initial state, the distance between the fastening portion 521 (or the fastening portion 521') and the rotation axis A is larger than that of the second housing 300 The distance of the surface 301 from the axis of rotation A. Here, the distance between the fastening portion 521 (or the fastening portion 521') and the rotation axis A is defined as the average distance between the points on the fastening portion 521 (or the fastening portion 521') and the rotation axis A. In other words, the fastener 500 and its buckle portion 521 (or buckle portion 521') are independently installed outside the outer surface 301 of the second housing 300, so it is only necessary to provide the connection arm 520 (or connection arm 520') for temporary The deformed space does not need to provide a groove for accommodating the entire fastener 500, which is less restrictive than conventional locking structures. Thereby, the structural complexity of the first casing 200 or the second casing 300 can be effectively reduced.

需特別說明的是，本發明中的暫時形變係指受到一施力所造成形狀上的暫時性的改變，如彎曲、扭轉、變形等。這些的形變通常導致一彈性位能，而在前述施力消失後以復位的形式釋放彈性位能。It should be particularly noted that the temporary deformation in the present invention refers to a temporary change in shape caused by an applied force, such as bending, twisting, and deformation. These deformations usually result in an elastic potential energy, and the elastic potential energy is released in the form of reset after the aforementioned force disappears.

此外，相較於習用鎖定結構的預壓做法，本實施方式之扣件500在觸發鎖定機制前為自由狀態，因此也不需設置預壓扣件500的凸出部位，可避免因第一殼體200的形狀特殊而造成脫模困難問題。In addition, compared to the conventional pre-compression method of the locking structure, the fastener 500 of this embodiment is in a free state before the locking mechanism is triggered, so there is no need to provide a protruding portion of the pre-pressure fastener 500, which can avoid the first shell The special shape of the body 200 causes difficulty in demolding.

本文件所揭露的霧化給藥裝置之鎖定結構僅需在第一殼體設置定位用的扣槽，扣件之扣接部在進入扣槽前為自由端，不採用須預壓的彈片元件，也不須在組裝同時保持對齊預壓位置，因此製造成本與結構複雜性較低，並可防止霧化給藥裝置被錯誤地鎖定。本發明在上文中已以較佳實施例揭露，然熟習本項技術者應理解的是，該實施例僅用於描繪本發明，而不應解讀為限制本發明之範圍。應注意的是，舉凡與該實施例等效之變化與置換，均應設為涵蓋於本發明之範疇內。因此，本發明之保護範圍當以申請專利範圍所界定者為準。The locking structure of the atomized drug delivery device disclosed in this document only needs to be provided with a buckle groove for positioning in the first housing, and the buckle portion of the buckle is a free end before entering the buckle groove, and no preloaded shrapnel element is used It is not necessary to maintain the alignment pre-compression position during assembly, so the manufacturing cost and structural complexity are low, and the atomized drug delivery device can be prevented from being erroneously locked.
