Description
本發明是有關於一種呼氣閥，特別是指一種適用於一個呼吸防護具的呼氣閥。The present invention relates to an exhalation valve, and more particularly to an exhalation valve suitable for use in a respiratory protection device.
呼吸防護具，俗稱口罩，在此稱呼吸罩，有濾除外界空氣防護個人呼吸系統的功能，然而往往因為穿戴者無法忍受所呼出的溼熱汙濁空氣容留累積在呼吸罩中，而不喜歡穿戴或難以忍受長時間穿戴。為解決此問題，早已經有發明在口罩面體裝設呼氣閥，讓這些濕熱汙濁的空氣能夠省力且快速地排出口罩之外。呼氣閥為一種單向閥，只允許罩內氣體流向罩外，而不允許罩外氣體流向罩內，所以罩外空氣仍必須通過濾材或吸附罐才能進入罩內，並不會造成讓外界空氣進入罩內的捷徑，無減損於淨化外界空氣的功效。Respiratory protective gear, commonly known as a respirator, is called a respirator. It has the function of filtering the air to protect the individual's respiratory system. However, it is often because the wearer can't stand the hot and humid air that is exhaled and accumulates in the respirator, rather than wearing or Unbearable to wear for a long time. In order to solve this problem, it has been invented to install an exhalation valve in the mask face body, so that these hot and dirty air can be saved and quickly discharged outside the cover. The exhalation valve is a one-way valve that only allows the gas in the hood to flow out of the hood, and does not allow the gas outside the hood to flow into the hood, so the air outside the hood must still pass through the filter or the sump to enter the hood without causing the outside world to be The shortcut of air into the hood does not detract from the effect of purifying the outside air.
參閱圖1、圖2，根據前述，為了減輕配載口罩所帶來的不舒適感，一種如CN102695549號專利發明人南森·A·亞伯等人所揭示的過濾面罩1，主要包含一個面罩體11，及設置在該面罩體11之外表面的一個單向閥12。該單向閥12包括形成有一個閥孔120的一個閥座121、與該閥座121對合的一個閥蓋122、可開啟地覆蓋該閥孔120周圍之密封面且一端被固定在該閥座121與該閥蓋122間的一個閥瓣123，及形成在該閥蓋122且避免該閥瓣123沾黏於該閥蓋122的一個凸起124。該閥蓋122具有形成在左、右二側及下側的數個開口1221。藉此，由於該閥瓣123只能單向開啟，因此，可以使呼出的氣流從該面罩體11內經該閥孔120流向該閥瓣123，使該閥瓣123脫離密封面而開放該閥孔120，允許氣流通過該等開口1221快速且大量的向外排氣，進而達到減少容留廢氣量的目的。Referring to Figures 1 and 2, in order to reduce the discomfort caused by the loading of the mask, a filtering mask 1 as disclosed by the inventor of CN102695549, Nansen A. Aber, et al., mainly comprises a mask body. 11. A one-way valve 12 disposed on an outer surface of the mask body 11. The one-way valve 12 includes a valve seat 121 formed with a valve hole 120, a valve cover 122 that is engaged with the valve seat 121, a sealing surface that openably covers the periphery of the valve hole 120, and one end of which is fixed to the valve A valve flap 123 between the seat 121 and the valve cover 122, and a protrusion 124 formed on the valve cover 122 and preventing the valve flap 123 from sticking to the valve cover 122. The valve cover 122 has a plurality of openings 1221 formed on the left and right sides and the lower side. Therefore, since the valve flap 123 can only be opened in one direction, the exhaled airflow can flow from the mask body 11 through the valve hole 120 to the valve flap 123, and the valve flap 123 can be disengaged from the sealing surface to open the valve hole. 120, allowing the airflow to be quickly and massively exhausted through the openings 1221, thereby achieving the purpose of reducing the amount of exhaust gas.
惟，該單向閥12雖然提供了快速省力將呼氣排出該過濾面罩1的功能，卻也產生了一個問題，就是使該面罩體11的吸氣較為費力。理論上而言，因為該單向閥12為不透氣性，且只准氣體流出不准流進，所以該單向閥12佔據在該面罩體11的面積，即是減損該面罩體11的透氣面積，因而升高吸氣阻抗，尤其當該面罩體11的總面積越小時，其吸氣阻抗升高的程度越發嚴重。However, although the check valve 12 provides a quick and labor-saving function of expelling exhalation out of the filtering mask 1, it also causes a problem that the inhalation of the mask body 11 is laborious. Theoretically, since the one-way valve 12 is impermeable to air and only the gas outflow is allowed to flow in, the check valve 12 occupies the area of the mask body 11, that is, the ventilation of the mask body 11 is impaired. The area, thus increasing the inspiratory impedance, especially as the total area of the mask body 11 is smaller, the degree of increase in the inspiratory impedance becomes more serious.
參閱圖3，尤其是，當前述單向閥12配置在如中華民國專利號第M258752號專利案發明人廖春榮所揭露之一種具有隔層之面體2時，會因為該面體2區分成上、下分離不相連通且相對鼻部的一個上內側空間21與相對口部的一個下內側空間22，而只能選擇相對該上內側空間21而設置在該面體2上半部，會因為該面體2上半部空間變小而不易安裝，所以必需縮小呼氣閥的基底面積。Referring to FIG. 3, in particular, when the one-way valve 12 is disposed in a face body 2 having a compartment as disclosed by Liao Chunrong, the inventor of the Patent No. M258752 of the Republic of China Patent No. M258752, the face body 2 is divided into upper faces. And separating one upper inner space 21 of the opposite nose and one lower inner space 22 of the opposite mouth, and only being able to be disposed opposite to the upper inner space 21 and disposed in the upper half of the upper body 2, The upper half of the face body 2 becomes small and is not easy to install, so it is necessary to reduce the area of the base of the exhalation valve.
因此，本發明的目的，即在提供一種增加空間效益，以提升吸氣時的進氣量，及減少悶熱感，且能夠避免影響視線，而提高使用呼吸罩之意願的呼氣閥。Accordingly, it is an object of the present invention to provide an exhalation valve that increases the space efficiency to increase the amount of intake air during inhalation, and to reduce the sultry sensation, and to avoid affecting the line of sight and to increase the willingness to use the respirator.

The respiratory protection device includes a face body having a hole, and the exhalation valve includes : a housing, and a first valve flap.
該殼體相對該面體的孔洞接合於該面體，且佔據該面體的一個基底面積不大於1400 mm 2，該殼體界定出一個空腔，並具有一個底板、形成在該底板且連通於該空腔與該面體內部的一個閥口、形成在該底板且環繞該閥口的一個密封面，及連通於該空腔與外界的至少一個排氣口。 The housing is joined to the face body with a hole of the face body, and a base area occupying the face body is no more than 1400 mm 2 , the case defines a cavity, and has a bottom plate formed on the bottom plate and connected a valve port inside the cavity and the face body, a sealing surface formed on the bottom plate and surrounding the valve port, and at least one exhaust port communicating with the cavity and the outside.
該第一閥瓣相對該殼體的閥口覆蓋在該密封面，且沿一條長度方向延伸，並具有形成在一端部且相對該閥座固定不動的一個固定部，及形成另一端部且能夠被氣流推動而開放該閥口的一個活動部，使氣流從該面體內部單向通過該閥口進入該空腔後，由該排氣口向外排氣。The first valve flap covers the sealing surface of the housing and extends along a length direction, and has a fixing portion formed at one end portion and fixed to the valve seat, and the other end portion is formed and capable of being formed The movable portion of the valve port is opened by the airflow, so that the airflow enters the cavity from the inside of the face body through the valve port, and is exhausted outward by the exhaust port.
本發明之功效在於：在不影響氣流流動之順暢性的情形下，縮小整體所佔的面積，進而提升空間效益與過濾面體吸氣時的進氣量，及減少悶熱感，且能夠避免影響視線，而提高使用意願，及容易裝設在其他配件互斥的面體上。The utility model has the advantages that the overall occupied area is reduced without affecting the smoothness of the airflow, thereby improving the space efficiency and the intake air amount when the filter body is inhaled, and reducing the feeling of stuffiness, and avoiding the influence. Sight, and will increase the willingness to use, and easy to install on the face of other accessories.

The respiratory protection device 2 includes a face body 21 mounted on the face, a partition 22 disposed on the inner surface of the face body 21, and a second flap 23 disposed on the partition 22. The face body 21 has a hole 211. The partition 22, together with the face body 21 and the face, defines an upper air chamber 221 that is separated from the upper and lower portions and a lower air chamber 222 that faces the mouth. The second flap 23 allows the air flow to flow unidirectionally from the lower plenum 222 toward the upper plenum 221 . In the present embodiment, the housing 100 is joined to the side of the face body 21 with the hole 211 of the face body 21, and the cavity 40 communicates with the upper air chamber 221 through the hole 211 and the valve port 31.
接下來，先對本發明前述構造進行定義：Next, the foregoing configuration of the present invention is first defined:
在本實施例中，將基底面積A定義為，該殼體100投影在該閥座3之底板30的面積。該基底面積A等於或幾乎等於本發明之呼氣閥接合在該面體21之孔洞211外圍所佔據的面積，這樣的定義，也更能夠顯示本發明之呼氣閥與其他配件在該面體21上配置時的相斥情形。In the present embodiment, the substrate area A is defined as the area in which the casing 100 is projected on the bottom plate 30 of the valve seat 3. The base area A is equal to or nearly equal to the area occupied by the exhalation valve of the present invention engaged on the periphery of the hole 211 of the body 21, and such a definition is also more capable of showing the exhalation valve and other fittings of the present invention in the face. The repulsion situation when configuring on 21 .
在本實施例，定義為該閥蓋4之頂壁42相距於該閥座3之底板30的最大高度H(如圖10)。將該殼體100高度維持在習知技術已有技術的水準，不會因為限縮該基底面積A而加大殼體100高度，避免影響穿戴者的視野。另外，將前述閉側部500與開側部400設定在人臉的上方與下方。In the present embodiment, it is defined that the top wall 42 of the valve cover 4 is apart from the maximum height H of the bottom plate 30 of the valve seat 3 (Fig. 10). The height of the housing 100 is maintained at the level of the prior art of the prior art, and the height of the housing 100 is not increased by limiting the area A of the substrate, thereby avoiding affecting the field of view of the wearer. Further, the closed side portion 500 and the open side portion 400 are set above and below the human face.
參閱圖6，當人以口部或鼻部吸氣時，外界的氣流會通過該面體21，而被該隔板22區隔形成二股分流。其中一股分流，由該面體21進入該下氣室42，除了可以提供人之口部吸氣所需外，且會推動該第二閥瓣23，使該第二閥瓣23允許氣流單向由該下氣室222朝該上氣室221流動。另一股分流，則直接由該面體21進入該上氣室221，與由該下氣室222進入該上氣室221的氣流匯集，而擴增該上氣室221的進氣量，提供人之鼻部吸氣所需。詳如中華民國專利申請號第106121089號申請案所載，於此不再贅述。Referring to Fig. 6, when a person inhales in the mouth or nose, an external airflow passes through the body 21, and the partition 22 is divided to form two shunts. One of the diverts enters the lower plenum 42 from the face 21, and in addition to providing the mouth for the person to inhale, and pushes the second flap 23, so that the second flap 23 allows the air flow The lower air chamber 222 flows toward the upper air chamber 221 . The other split flow directly enters the upper air chamber 221 from the face body 21, and collects airflow entering the upper air chamber 221 from the lower air chamber 222, thereby amplifying the intake air amount of the upper air chamber 221, and providing The nose of the person needs to breathe. For details, please refer to the application of the Republic of China Patent Application No. 106121089, which will not be repeated here.
當人透過鼻部呼出廢氣時，呼出的氣流會因為受阻於該隔板22與該第二閥瓣23，使該氣流無法流入該下氣室222，而侷限在該上氣室221內，參閱圖8、圖9，該上氣室221因為呼氣所產生的正壓，而推動該第一閥瓣5的活動部52，使該閥瓣5的活動部52由該封閉位置朝反向於該閥口31的方向在該空腔40內活動，至受阻於該限位柱43而位於該開放位置，且開放該閥口31。藉此，使該上氣室221內的廢氣從該面體21的上氣室221單向通過該閥口31進入該空腔40後，由前部300及開側部400的該等排氣口412向外排氣。When a person exhales the exhaust gas through the nose, the exhaled airflow is restricted to the partition 22 and the second flap 23, so that the airflow cannot flow into the lower air chamber 222, and is confined in the upper air chamber 221, see 8 and 9, the upper air chamber 221 pushes the movable portion 52 of the first flap 5 due to the positive pressure generated by the exhalation, so that the movable portion 52 of the flap 5 is reversed from the closed position. The direction of the valve port 31 is movable within the cavity 40 to be blocked by the limit post 43 in the open position, and the valve port 31 is opened. Thereby, the exhaust gas in the upper air chamber 221 is unidirectionally passed through the valve port 31 from the upper air chamber 221 of the surface body 21 into the cavity 40, and the exhaust gas from the front portion 300 and the open side portion 400 is exhausted. Port 412 is vented outward.
參閱圖9、圖10，當該第一閥瓣5的活動部52位於該開放位置時，氣流會由該活動部52竄流，此時，由該活動部52相對於該閥蓋4前部300及開側部400竄流的氣流，會直接由該閥蓋4前部300、開側部400之排氣口412分別朝下及朝向臉面前方排出，由該活動部52往人臉上側方向竄流的氣流到達該閥蓋4閉側部500的圍繞壁41且受阻擋後，會如圖11所示，通過該第一閥瓣5與該閥蓋4之頂壁42間的間距空間，且依循該限位柱43之圓柱造型的弧面，形成順利通過該限位柱43二側的二股分流，而同樣由前部300及開側部400即相對於該活動部52往人臉下側方向之排氣口412分別朝下及朝向臉面前方排出。Referring to FIG. 9 and FIG. 10, when the movable portion 52 of the first flap 5 is located at the open position, the airflow is turbulent by the movable portion 52. At this time, the movable portion 52 is opposite to the front portion of the bonnet 4. The turbulent flow of the 300 and the open side portion 400 is directly discharged from the front portion 300 of the bonnet 4 and the exhaust port 412 of the open side portion 400 toward the front and toward the front of the face, respectively. After the turbulent airflow reaches the surrounding wall 41 of the closed side portion 500 of the valve cover 4 and is blocked, as shown in FIG. 11, the space between the first valve flap 5 and the top wall 42 of the valve cover 4 is And following the curved surface of the cylindrical shape of the limiting column 43, the two shunts passing through the two sides of the limiting column 43 are formed, and the front portion 300 and the open side portion 400 are opposite to the movable portion 52. The exhaust ports 412 in the lateral direction are discharged downward and toward the front of the face, respectively.
參閱圖6、圖9，當人透過口部呼氣時，呼出的氣流除了會通過該面體21而排出外界外，同樣會推動該第二閥瓣23，使該第二閥瓣23允許氣流單向由該下氣室222朝該上氣室221流動，且由該上氣室221經該面體21，及本發明的呼氣閥快速的排出。藉此，對於空間較大的下氣室222而言，如果口部不持續呼出廢氣，則呼出的廢氣可以在數次被抽向該上氣室221，及排出的過程中，逐漸地減少該下氣室222的廢氣含量，而能夠提升吸氣時新鮮空氣的含量，而減少悶熱感。Referring to FIG. 6 and FIG. 9, when a person exhales through the mouth, the exhaled airflow is discharged outside the outside through the face body 21, and the second valve flap 23 is also pushed to allow the second valve flap 23 to allow airflow. One-way flow from the lower air chamber 222 toward the upper air chamber 221, and the upper air chamber 221 is quickly discharged through the face body 21 and the exhalation valve of the present invention. Thereby, for the lower air chamber 222 having a large space, if the mouth portion does not continuously exhale the exhaust gas, the exhaled exhaust gas can be gradually reduced to the upper air chamber 221 several times, and during the discharge process, gradually reduce the The exhaust gas content of the lower air chamber 222 can increase the content of fresh air at the time of inhalation, and reduce the feeling of sultry heat.
參閱圖6與圖8，在本實施例中，該殼體100是以面向該面體21的該接合面301，相對該面體21的孔洞211接合於該面體21。該接合面301能夠以高週波、或超音波、或熱壓、或黏結等方式接合於該面體21，當不以此為限。另外，該接合面301也可以形成在該閥蓋4之圍繞壁41的凸緣，由於本領域中具有通常知識者根據以上說明可以推知擴充細節，因此不多加說明。Referring to FIGS. 6 and 8, in the present embodiment, the housing 100 is the joint surface 301 facing the surface body 21, and the hole 211 of the surface body 21 is joined to the surface body 21. The joint surface 301 can be joined to the surface body 21 by high frequency, ultrasonic wave, hot pressing, or bonding, etc., without being limited thereto. In addition, the joint surface 301 may also be formed on the flange of the valve cover 4 surrounding the wall 41. Since those skilled in the art can infer the details of the expansion according to the above description, it will not be described.
參閱圖12、圖13與圖14，是本發明一個第二實施例，其與該第一實施例大致相同，不同處在於：Referring to FIG. 12, FIG. 13, and FIG. 14, a second embodiment of the present invention is substantially the same as the first embodiment, and the difference lies in:
該閥座3的底板30與環牆33呈橢圓形，還包括一個凸緣部302，及形成在該凸緣部302且面向該面體21的一個接合面303。且該環牆33與該密封面32間相對於該開側部400與閉側部500的間距大於第一實施例，並具有形成在一外表面的一個凸環331。The bottom plate 30 of the valve seat 3 and the ring wall 33 are elliptical, and further include a flange portion 302, and a joint surface 303 formed on the flange portion 302 and facing the face body 21. And the distance between the annular wall 33 and the sealing surface 32 relative to the opening side portion 400 and the closing side portion 500 is larger than that of the first embodiment, and has a convex ring 331 formed on an outer surface.
該閥蓋4的圍繞壁41與該閥座3的凸環331卡合，且還包括另一個凸緣44。該凸緣44的形狀與該閥座3之底板30的凸緣部302形狀配合，並具有面向該面體21的一個接合面441。該凸緣部302、該凸緣44分別夾迫在該面體21之內表面與外表面，使該等接合面303、441相互面對且接合於該面體21，而與該面體21氣密接觸。該基底面積A等於該閥座3及其凸緣部302與該閥蓋4及其凸緣33在該面體21上所佔據的面積。The surrounding wall 41 of the valve cover 4 engages with the convex ring 331 of the valve seat 3 and further includes another flange 44. The flange 44 has a shape that matches the flange portion 302 of the bottom plate 30 of the valve seat 3 and has a joint surface 441 facing the face body 21. The flange portion 302 and the flange 44 are respectively clamped to the inner surface and the outer surface of the face body 21 such that the joint faces 303, 441 face each other and are joined to the face body 21, and the face body 21 Airtight contact. The base area A is equal to the area occupied by the valve seat 3 and its flange portion 302 and the valve cover 4 and its flange 33 on the face body 21.
藉此，前述凸緣部302與凸緣33同樣可以達到接合該面體21的目的，另外，改變該等排氣口412的設置位置，使得該開側部400與該閉側部500位置對調，而反向於圖4~圖11的設計，使本發明在本實施例中，該殼體100是接合於該面體21相對鼻子的另一側，由於本領域中具有通常知識者根據以上說明可以推知擴充細節，因此不多加說明。Thereby, the flange portion 302 and the flange 33 can achieve the purpose of joining the surface body 21, and the position of the exhaust port 412 is changed such that the opening side portion 400 and the closed side portion 500 are oppositely adjusted. In contrast to the design of FIGS. 4-11, in the present embodiment, the housing 100 is joined to the other side of the face 21 opposite the nose, as is generally known in the art. The description can infer the details of the expansion, so there is no more explanation.
且重要的是，該底板30的凸緣部302與凸緣44呈橢圓形，因此，可進一步縮小該基底面積A在該面體21上所佔據的面積，而不大於1000 mm 2。且該環牆33也構造成橢圓形，可以強化上面的凸環331與該閥蓋4的結扣力，並相對於該開側部400與閉側部500加大與該密封面32間的間距，相較於該第一實施例的設計，可以使由該活動部52相對於該閥蓋4之閉側部300及開側部400竄流的氣流，具有足夠的空間朝該閉側部300與該開側部400流動，且朝該閉側部300流動的氣流，同樣在到達該閥蓋4的圍繞壁41且受阻擋後，而如圖14所示，轉折向上並通過該第一閥瓣5與該閥蓋4之頂壁42間的間距空間，而同樣相對於該等排氣口412分別朝下及朝向臉面前方排出。 What is important is that the flange portion 302 of the bottom plate 30 and the flange 44 are elliptical, and therefore, the area occupied by the base area A on the surface body 21 can be further reduced, and is not more than 1000 mm 2 . The ring wall 33 is also configured in an elliptical shape to strengthen the fastening force of the upper convex ring 331 and the valve cover 4, and is enlarged relative to the opening side portion 400 and the closed side portion 500 and the sealing surface 32. With respect to the design of the first embodiment, the airflow turbulent by the movable portion 52 with respect to the closed side portion 300 and the open side portion 400 of the valve cover 4 can have sufficient space toward the closed side portion. 300 and the open side portion 400 flow, and the air flow flowing toward the closed side portion 300 is also after reaching the surrounding wall 41 of the valve cover 4 and blocked, and as shown in FIG. 14, turning upward and passing the first The space between the valve flap 5 and the top wall 42 of the valve cover 4 is also discharged toward the front and toward the front of the face, respectively, with respect to the exhaust ports 412.
參閱圖15，是本發明一個第三實施例，其與該第一實施例大致相同，不同處在於：Referring to Figure 15, there is shown a third embodiment of the present invention which is substantially identical to the first embodiment except that:
該殼體100適用於沒有安裝該隔板22的面體21。且該等排氣口412形成在該圍繞壁41且相對於靠近該閥口31之兩個長邊311的兩個側部600，使該殼體100的前部300與該等側部600分別有對稱的排氣口412，藉此，該殼體100安裝在該面體21靠近鼻子下方的位置，使得後部200朝向臉面上方，前部300朝向臉面下方，而同樣能夠將呼出的氣流，往人臉下側方向及二側方向之排氣口412分別朝下及朝向臉面二側排出，並加速氣流排出的速度。The housing 100 is suitable for the face body 21 in which the partition 22 is not mounted. And the exhaust ports 412 are formed on the surrounding wall 41 and opposite to the two side portions 600 of the two long sides 311 of the valve port 31, so that the front portion 300 of the casing 100 and the side portions 600 are respectively There is a symmetrical exhaust port 412, whereby the housing 100 is mounted at a position below the nose 21 near the nose such that the rear portion 200 faces the upper side of the face and the front portion 300 faces below the face, and the exhaled airflow can also be The exhaust port 412 in the lower side direction and the two side directions of the face are respectively discharged downward and toward the two sides of the face, and accelerate the speed at which the airflow is discharged.
經由以上的說明，可將前述實施例的優點歸納如下：Through the above description, the advantages of the foregoing embodiments can be summarized as follows:
1、更進一步的說，本發明其中一設計目標，就是一種較小基底面積A的呼氣閥，而本發明之呼氣閥的基底面積A不大於1000 mm 2，足夠小到可以裝設在嘴巴以上且鼻部周圍的面體21上，不但能夠縮小整體所佔的面積，而進一步適用於小孩的口罩上，且在該基底面積A明顯小於前述CN102695549號專利的情形下，會因為所佔面積減少，而提升進入該面體21內部的新鮮空氣量，並減小呼吸阻抗。 1. Further, one of the design goals of the present invention is an exhalation valve having a smaller base area A, and the exhalation valve of the present invention has a base area A of not more than 1000 mm 2 , which is small enough to be mounted on The face 21 above the mouth and around the nose can not only reduce the overall area, but is further suitable for children's masks, and in the case where the substrate area A is significantly smaller than the aforementioned CN102695549 patent, it will be occupied. The area is reduced, and the amount of fresh air entering the inside of the face body 21 is increased, and the respiratory impedance is reduced.
2、本發明另一個設計目標，就是該殼體100的最大高度H，將該殼體100的最大高度H維持在習知技術已有技術的水準，不要因為限縮該基底面積A而加大該殼體100的最大高度H，能夠避免影響穿戴者的視野。2. Another design object of the present invention is the maximum height H of the housing 100, maintaining the maximum height H of the housing 100 at the level of the prior art of the prior art, and not increasing the area A of the substrate. The maximum height H of the housing 100 can avoid affecting the wearer's field of view.
3、本發明的呼氣閥，在減少於該面體21所佔據面積的同時，將該殼體100較偏向水平設置而非重直設置，並將該殼體100設計成較狹長，如此可以容易安裝在前述嘴上鼻旁的面體21上。以下的處置能將該殼體100變成前述狹長，即維持或小幅度改變該閥口31在該長度方向X的徑寬，並較大幅度縮小該寬度方向Y的徑寬，同時該懸臂式之第一閥瓣5配合該閥31做徑寬改變。如此處置不會加大氣流推動該第一閥瓣5位於該開放位置的功，而維持同樣省力。3. The exhalation valve of the present invention, while reducing the area occupied by the face body 21, the housing 100 is disposed horizontally rather than vertically, and the housing 100 is designed to be narrow and long, so that It is easy to install on the face 21 on the nose of the aforementioned mouth. The following treatment can change the casing 100 to the aforementioned length, that is, maintain or slightly change the diameter of the valve port 31 in the longitudinal direction X, and greatly reduce the diameter of the width direction Y, and the cantilever type The first flap 5 cooperates with the valve 31 to vary the diameter. Such a treatment does not increase the flow of air to push the first flap 5 in the open position, while maintaining the same effort.
4、另外，由於該殼體100較偏向水平設置，如此較佳地將該等排氣口412設置在面體21的朝下側和視線前方，亦即該殼體100的前部300朝視線前方、開側部400朝下、閉側部500朝上，由前部300與開側部400順利將呼氣排除，而閉側部500阻擋廢氣排出，避免影響視線或模糊眼鏡。該等排氣412不對稱於該殼體100，跟巿面上呼吸罩之呼氣閥垂直設置，且其排氣口皆對稱於殼體，及朝下和側部靠下的設計，是很大的不同。4. In addition, since the casing 100 is disposed horizontally, it is preferable to arrange the exhaust ports 412 on the downward side of the face body 21 and in front of the line of sight, that is, the front portion 300 of the casing 100 faces the line of sight. The front side, the open side portion 400 faces downward, and the closed side portion 500 faces upward, and the exhalation is smoothly removed by the front portion 300 and the open side portion 400, and the closed side portion 500 blocks exhaust gas discharge to avoid affecting the line of sight or blurring the glasses. The exhaust 412 is asymmetric with respect to the housing 100, and is disposed perpendicular to the exhalation valve of the respirator on the heel surface, and the exhaust ports are symmetric with respect to the housing, and the design is downward and side down. Big difference.
5、再者，以該限位柱43特殊的造型設計，除了可以使該第一閥瓣5之活動部52位於該開放位置時，與該閥蓋4的頂壁42形成有供氣流通過的低層空間外，還能避免該活動部52沾黏於該閥蓋4的頂壁42，且重要的是，被開側部阻擋的氣流，可藉通過前述低層空間，使氣流依循該限位柱43之圓柱造型的弧面，順利地通過該限位柱43，而提升排氣時的速度與順暢性。5. Further, in the special design of the limiting post 43, in addition to the movable portion 52 of the first flap 5 being located in the open position, a top wall 42 of the valve cover 4 is formed with a flow for airflow. Outside the low-level space, the movable portion 52 can be prevented from sticking to the top wall 42 of the valve cover 4, and it is important that the airflow blocked by the open side portion can pass the aforementioned low-level space, so that the airflow follows the limit column. The curved surface of the cylindrical shape of 43 smoothly passes through the limit column 43 to improve the speed and smoothness of the exhaust.
惟以上所述者，僅為本發明的實施例而已，當不能以此限定本發明實施的範圍，凡是依本發明申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本發明專利涵蓋的範圍內。However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
