Description
本創作與呼吸面罩、過濾面罩或防毒面罩等面罩有關,尤其涉及設於此類面罩上之排氣裝置、進氣過濾裝置、與用於接觸臉部的環狀氣囊等方面的結構設計。 The present invention relates to a mask such as a breathing mask, a filtering mask or a gas mask, and particularly relates to a structural design of an exhaust device, an air intake filter device, and an annular airbag for contacting a face, which are provided on such a mask.
習知的面罩較常見者有呼吸面罩與防毒面罩,前者係用於協助病人呼吸,例如氧氣面罩或醫療用呼吸面罩,後者則用於過濾空氣中的有害物質或是環境污染物,例如噴塗油漆工作人員需要配戴防毒面罩來過濾有毒物質。無論哪一種面罩,都需要考量到使用者配戴面罩的舒適度,例如,第十五圖所示的一種習知呼吸面罩4,其在一罩體41的後側固設有一環形氣囊42供接觸使用者的臉部,以提供柔軟、舒適的觸感給使用者。然而,由於環形氣囊42係黏固在罩體41上或跟罩體41一體成形而不具備可拆裝之功能,因此,只要環形氣囊42出現漏氣、變形、損壞等不良情形或有吸附過多細菌、病毒、環境污染物等疑慮時,整個呼吸面罩4就需丟棄而形成浪費。 Conventional masks are more common with respiratory masks and gas masks. The former is used to assist patients in breathing, such as oxygen masks or medical respiratory masks, while the latter is used to filter harmful substances in the air or environmental pollutants, such as spray paint. Workers need to wear a gas mask to filter toxic substances. Regardless of the type of mask, it is necessary to consider the comfort of the user wearing the mask. For example, a conventional breathing mask 4 shown in Fig. 15 is provided with an annular airbag 42 on the rear side of a cover 41. Touch the user's face to provide a soft, comfortable touch to the user. However, since the annular airbag 42 is adhered to the cover 41 or integrally formed with the cover 41 and does not have a detachable function, as long as the annular airbag 42 is in a bad situation such as air leakage, deformation, damage, or excessive adsorption. When the bacteria, viruses, environmental pollutants, etc. are suspected, the entire breathing mask 4 needs to be discarded and waste.
再者,對於防毒面罩或具有空氣濾淨作用的過濾面罩而言,在其排氣口的部份通常設有膜片式的單向閥門,讓使用者吐出的氣向外排出,及阻止外面的空氣由此進入(外面的空氣是經由面罩的進氣過濾裝置被吸入面罩內),故使用者需要維持一定的吐氣力道,才能推開該單向閥門,然而,使用者的吐氣力道難以維持一致,尤其是在身體虛弱的狀況下,往往會出現沒有完全推開該單向閥門的狀況,導致所吐出的氣殘留太多, 影響面罩內部空氣的新鮮度,難以確保使用者可吸到清新的空氣。 Furthermore, for a gas mask or a filter mask having an air filtering effect, a diaphragm type one-way valve is usually provided at a portion of the exhaust port to allow the user to discharge the gas outward and block the outside. The air enters (the outside air is sucked into the mask through the air intake filter of the mask), so the user needs to maintain a certain exhalation force to push the one-way valve. However, the user's exhalation force is difficult to maintain. Consistent, especially in a weak state, there is often a situation in which the one-way valve is not fully pushed open, resulting in too much residual gas. Affecting the freshness of the air inside the mask makes it difficult to ensure that the user can breathe fresh air.
此外,該進氣過濾裝置本身對於所吸入的空氣通常會形成一定的阻力,影響使用者吸氣的順暢性。 In addition, the air intake filter device itself usually forms a certain resistance to the inhaled air, which affects the smoothness of the user's inhalation.
因此,習知面罩至少尚有上述問題亟待解決。 Therefore, the conventional mask has at least the above problems to be solved.

For example, the mask 1 further includes two coupling seats 16 that are engaged in the two air inlets 113 of the cover 11 and the air intake filter device 15 is connected to the air inlet 113 by the coupling seat 16. More specifically, the two coupling seats 16 each define a through hole 160 and an engaging groove 161 surrounding the through hole 160. The coupling seat 16 is made of an elastic non-foaming plastic material, in this embodiment. Thermoplastic rubber is used in the middle, but not limited to this. Preferably, the air inlet 113 is slightly smaller than the coupling seat 16 so that the resilient coupling seat 16 is tightly inserted into the air inlet 113, so that the air inlet 113 has no leakage concerns, as shown in the sixth figure. Each of the two air inlet filter devices 15 is provided with a coupling tube 151 which is inserted into the engagement groove 161 of the two coupling seats 16 to be engaged.

The figure shows. Through the above arrangement, the two coupling seats 16 are directly inserted into the corresponding air inlets 113, and the two air inlet filtering devices 15 are directly inserted into the coupling seat 16, so that the coupling seat 16 and the air inlet filtering device 15 are easily disassembled, assembled, and loaded. After good, the airtightness can be maintained, and the outside air is prevented from infiltrating into the cover 11 without the air intake filter device 15.
請再參見第五、七圖所示,排氣裝置14具有一連接管14b及多個孔14a,其內部可選擇性地設置簡單的濾材(圖中未示),較佳地,連接管14b螺接於罩體11,但不以此為限,例如,也可選擇上述進氣過濾裝置15藉由結合管151與結合座16而連接於罩體11之方式。如此,罩體11內的氣體可經由連接管14b、濾材及孔14a排到外面。請再參見第五、六圖,兩進氣過濾裝置15具有多個孔15a,且內部有濾材及/或吸收材料(圖中未示),吸收材料可選擇活性碳或其它可吸附環境污染物、有毒物質或有害物質的材料,從外面被吸入的空氣係經過兩進氣過濾裝置15的濾材及/或吸收材料的過濾後才經過結合管151、結合座16而進入到罩體11內。 Referring to FIG. 5 and FIG. 7 again, the exhaust device 14 has a connecting tube 14b and a plurality of holes 14a. The inside of the exhaust device 14 can be selectively provided with a simple filter material (not shown). Preferably, the connecting tube 14b is screwed. The cover body 11 is connected to the cover body 11 by a combination of the tube 151 and the coupling seat 16 , for example, but not limited thereto. Thus, the gas in the cover 11 can be discharged to the outside via the connecting pipe 14b, the filter material, and the hole 14a. Referring to FIGS. 5 and 6 again, the two air intake filter devices 15 have a plurality of holes 15a, and have a filter material and/or an absorbing material (not shown) inside, and the absorbing material may be selected from activated carbon or other adsorbable environmental pollutants. The toxic substance or the toxic substance, the air sucked from the outside is filtered by the filter material and/or the absorbing material of the two air intake filter devices 15, and then passes through the joint pipe 151 and the joint seat 16 to enter the cover body 11.
如第六圖所示,面罩1更包括一進氣閥152及一導流通道153。僅以示意圖表示的進氣閥152可選用膜片式單向閥,只允許外面空氣進入罩體11內,不允許罩體11內的氣體排出罩體11外面。進氣閥152可選擇設於罩體11內,但也可選擇設於進氣過濾裝置15內部靠近罩體11的位置,例如結合管151內,故被吸入進氣過濾裝置15空氣於流經濾材及/或吸收材料之後,會經由進氣閥152單向地流入罩體11內而變成較潔淨的空氣供應給使用者。再者,僅以示意圖表示的導流通道153係設於進氣過濾裝置15內且具有兩相對端,導流通道153的內壁面係從遠離罩體11的一端向靠近罩體11的一端有弧度地逐漸內縮、傾斜,大體上形成漏斗狀或喇叭狀。如此,從外面進來的空氣經過兩進氣過濾裝置15的濾材及/或吸收材料的過濾之後,會被順暢地導流進入罩體11內部,降低進氣過濾裝置15對所吸入的空氣的阻力,提高使用者吸氣的順暢性。 As shown in the sixth figure, the mask 1 further includes an intake valve 152 and a flow guiding passage 153. The intake valve 152, which is only shown schematically, may be a diaphragm type one-way valve that allows only outside air to enter the enclosure 11 and does not allow gas within the enclosure 11 to exit the enclosure 11. The intake valve 152 may be optionally disposed in the cover body 11, but may alternatively be disposed at a position inside the air intake filter device 15 near the cover body 11, for example, in the inner tube 151, so that it is sucked into the air intake filter device 15 to flow through the air. After the filter material and/or the absorbing material, it flows into the hood 11 unidirectionally via the intake valve 152 to become a cleaner air supply to the user. Furthermore, only the flow guiding channel 153 shown in the schematic diagram is disposed in the air intake filter device 15 and has two opposite ends. The inner wall surface of the flow guiding channel 153 is from the end away from the cover 11 to the end near the cover 11. The curvature gradually retracts and slopes, and generally forms a funnel shape or a trumpet shape. Thus, the air coming in from the outside is smoothly guided into the inside of the cover 11 after being filtered by the filter material and/or the absorbing material of the two air intake filter devices 15, thereby reducing the resistance of the air intake filter device 15 to the sucked air. To improve the smoothness of the user's inhalation.
第七圖顯示面罩1更包括一排氣閥141,排氣裝置14內部還有一排氣模組142,較佳地,排氣裝置14內部還有一旁通道143。僅以示意圖表示的排氣閥141可選用膜片式單向閥,只允許罩體11內的氣體排出罩體11外面,不允許外面空氣進入罩體11內。排氣閥141可選擇設於罩體11內,一如圖中所示,但也可選擇設於排氣裝置14內部靠近罩體11的位置。僅以示意圖表示的排氣模組142包括一吸入通道142a、一排出通道142b及連接此兩者的一微型泵M。吸入通道142a與排出通道142b於圖中形成喇叭狀或漏斗狀,但具體形式不以此為限,重點在於前者一端連接微型泵M的一吸入口(圖中未示)且與連接管14b相通,後者一端連接微型泵M的一排出口(圖中未示)且與該些孔14a相通。罩體11內由使用者呼出的氣體可藉由微型泵M抽氣運作而經由排氣閥141、吸入通道142a、排出通道142b及孔14a而排出到罩體11外面。透過排氣模組142的設置,可自動將面罩1內的使用者呼出的氣體排送到面罩1外,保持罩體11內空氣的清新,並降低使用者呼氣上的負擔。依此概念,上述進氣過濾裝置15中也可選擇加設與排氣模組142相同或類似的一進氣模組(圖中未示),協助使用者吸氣,以減輕其吸氣上的負擔。 The seventh figure shows that the mask 1 further includes an exhaust valve 141. The exhaust unit 14 further has an exhaust module 142. Preferably, the exhaust unit 14 also has a bypass passage 143 therein. The exhaust valve 141, which is only schematically shown, may be a diaphragm type check valve that allows only the gas in the casing 11 to exit the outside of the casing 11, and does not allow outside air to enter the casing 11. The exhaust valve 141 may be optionally disposed within the cover 11, as shown in the figures, but may alternatively be disposed at a location within the exhaust 14 adjacent the cover 11. The exhaust module 142, which is only schematically shown, includes a suction passage 142a, a discharge passage 142b, and a micropump M that connects the two. The suction passage 142a and the discharge passage 142b are formed in a flared shape or a funnel shape in the figure, but the specific form is not limited thereto, and the focus is that one end of the former is connected to a suction port (not shown) of the micropump M and communicates with the connecting pipe 14b. One end of the latter is connected to a row of outlets (not shown) of the micropump M and communicates with the holes 14a. The gas exhaled by the user in the cover 11 can be discharged to the outside of the cover 11 via the exhaust valve 141, the suction passage 142a, the discharge passage 142b, and the hole 14a by the pumping operation of the micropump M. Through the arrangement of the exhaust module 142, the gas exhaled by the user in the mask 1 can be automatically discharged to the outside of the mask 1, and the air in the cover 11 can be kept fresh and the burden on the user's exhalation can be reduced. According to the concept, an air intake module (not shown) similar to or similar to the exhaust module 142 may be added to the air intake filter device 15 to assist the user to inhale to reduce the inhalation. The burden.
旁通道143係直接貫通吸入通道142a及排出通道142b,形 成繞過微型泵M的一排氣通路。旁通道143內設置有一閘門(圖中未示),排氣裝置14上對應設置有可讓使用者控制閘門開啟或關閉的一控制件(圖中未示),及設置可讓使用者控制微型泵M開啟與關閉的開關。當微型泵M被開啟,且該閘門被關閉而使旁通道143不導通吸入通道142a及排出通道142b時,罩體11內由使用者呼出的氣體可藉由微型泵M被強制排出到罩體11外,確保罩體11內空氣的清新。若使用者認為不需開啟微型泵M,則只要將閘門打開,以使旁通道143導通吸入通道142a及排出通道142b,此時罩體11內由使用者呼出的氣體就可透過由旁通道143、通道142a、排出通道142b及孔14a所形的該排出通路而排出到罩體11外面。在此實施例中,使用者就能視其需求,選擇利用微型泵M來協助排氣,或是選擇利用旁通道143來自主排氣。 The bypass passage 143 directly penetrates the suction passage 142a and the discharge passage 142b, and is shaped An exhaust passage that bypasses the micropump M. A gate (not shown) is disposed in the bypass channel 143. The exhaust device 14 is provided with a control member (not shown) for allowing the user to control the gate to be opened or closed, and the setting allows the user to control the miniature Pump M opens and closes the switch. When the micropump M is turned on and the gate is closed so that the bypass passage 143 does not conduct the suction passage 142a and the discharge passage 142b, the gas exhaled by the user in the cover 11 can be forcibly discharged to the cover by the micropump M. Outside of 11, ensure that the air inside the cover 11 is fresh. If the user thinks that the micropump M is not required to be turned on, the gate is opened to allow the bypass passage 143 to open the suction passage 142a and the discharge passage 142b. At this time, the gas exhaled by the user in the cover 11 can pass through the bypass passage 143. The discharge passage formed by the passage 142a, the discharge passage 142b, and the hole 14a is discharged to the outside of the cover 11. In this embodiment, the user can choose to utilize the micropump M to assist in the exhaust, or select to utilize the bypass passage 143 from the main exhaust, depending on the needs thereof.
