Description

一种呼吸装置A breathing device 技术领域Technical field
本发明涉及防护装置领域，具体而言，涉及一种呼吸装置。The invention relates to the field of protective devices, in particular to a breathing device.
背景技术Background technique
包括面罩本体的呼吸装置已成为一种具有很高的实用价值的装置，呼吸装置在用户的鼻部和口部上。在使用时，通过过滤结构，将受污染的环境空气与面罩内部分开，进而含颗粒、病菌等物体阻挡在面罩本体上，用于保护个人免于吸入存在于周围环境中的污染物。The breathing device including the mask body has become a device with high practical value, and the breathing device is on the nose and mouth of the user. When in use, the contaminated ambient air is separated from the inside of the mask through the filtering structure, and objects containing particles, germs, etc. are blocked on the mask body to protect individuals from inhaling pollutants in the surrounding environment.
在呼吸装置中，可折叠的呼吸装置是一种性能优异的类型，面罩本体因可通过折叠而提供了携带的便利性。为了在面罩本体内层和用户口鼻之间形成一定的气体空间，以及便于折叠面罩，人们在面罩的中心线上设置缝合线使面罩本体向外产生一定形变。随着技术的发展，缝合线通过激光焊接、超声波焊接等形成焊接区段实现缝合效果。Among breathing apparatuses, a foldable breathing apparatus is a type with excellent performance, and the mask body can be folded to provide convenience for carrying. In order to form a certain air space between the inner layer of the mask body and the user's mouth and nose, and to facilitate folding of the mask, people set sutures on the center line of the mask to make the mask body deform outward. With the development of technology, the stitching line is formed by laser welding, ultrasonic welding, etc. to form a welding section to achieve the stitching effect.
但现有技术存在缺陷，例如，市面上的可折叠的呼吸装置只有一条夹持条，对呼吸装置的取向做了限定，这对于不同性别、年龄的不同脸型用户而言，局限性是显而易见的，脸型的不同、使用习惯的不同，使得用户对口罩的佩戴多样性有了一定的需求，单一规格的口罩难以适用不同脸型的用户，导致部分人群(尤其是儿童)，由于鼻部高度低、鼻部区域的脸型小，导致鼻部的压条并不能很好的将面罩本体压紧于面部，只能购买特定型号的呼吸装置，有些情况下，由于货源限制等，使得部分人群甚至难以买到合适的呼吸装置。此外，可折叠的呼吸装置只有一条夹持条，设置于面罩本体上方，这对于不同脸型的用户使用而言，有密合性缺陷，尤其有些脸型的下颌后缩，或者瘦脸型的下颌不圆润，存在下颌密封不严的缺陷，使得呼吸装置的防护效果严重降低。此外，市面上的可折叠的呼吸装置下颌处仅靠面罩本体的无纺布层和过滤层提供面罩本体形态支撑，由于 布层的柔性，不足以维持呼吸装置口鼻处的立体结构，会使用户感觉口鼻部压迫。However, the prior art has drawbacks. For example, the foldable breathing apparatus on the market has only one clamping strip, which limits the orientation of the breathing apparatus. This limitation is obvious for users of different genders and ages with different facial shapes. Different face shapes and different usage habits make users have a certain demand for the diversity of wearing masks. It is difficult for a single-size mask to be suitable for users with different face shapes, resulting in some people (especially children), due to the low nose height, The face shape in the nose area is small, so that the pressure strips on the nose can’t press the mask body well on the face. You can only buy a specific type of breathing device. In some cases, due to supply restrictions, some people may even be difficult to buy. Suitable breathing apparatus. In addition, the foldable breathing device has only one clamping strip, which is set above the mask body, which has a tightness defect for users with different facial shapes, especially some facial jaws with receding jaws, or thin-face jaws that are not rounded , There is a defect that the lower jaw is not tightly sealed, which seriously reduces the protective effect of the breathing device. In addition, the foldable breathing apparatus on the market only relies on the non-woven fabric layer and filter layer of the mask body to provide the mask body shape support. Due to the flexibility of the cloth layer, it is not enough to maintain the three-dimensional structure of the mouth and nose of the breathing apparatus. The user feels pressure on the nose and mouth.
一部分现有技术中，缝合线的上下设置和角度设计不合理，使得用户的舒适度体验和面罩密合保护性较差。In a part of the prior art, the upper and lower setting and angle design of the suture are unreasonable, which makes the user's comfort experience and the tightness and protection of the mask poor.
一部分现有技术中，面罩的夹持件采用内置设计，当拉紧面罩带时，内置夹持件会随着面罩带拉扯变形，无法有效密封鼻部，防护效果较差。有的现有技术中采用外置夹持件设计，但将夹持件完全固定在外无纺布外侧，也存在类似缺陷。In a part of the prior art, the clamping piece of the mask adopts a built-in design. When the mask strap is tightened, the built-in clamping piece deforms as the mask strap is pulled, which cannot effectively seal the nose, and the protective effect is poor. Some prior art uses an external clamping piece design, but completely fixing the clamping piece on the outside of the outer non-woven fabric has similar defects.
此外，如今戴眼镜的人群日益增多，对于许多戴眼镜的用户而言，在使用面罩时面临的一个问题在于眼镜容易滑落。In addition, nowadays, the number of people wearing glasses is increasing. For many users who wear glasses, a problem they face when using a mask is that the glasses are easy to slip off.

本发明至少具有以下有益效果：The present invention has at least the following beneficial effects:
本发明中，第一可变形夹持条和第二可变形夹持条中的一个配置为通 过变形将面罩本体夹持于用户的鼻部，第一可变形夹持条和第二可变形夹持条中的另一个配置为通过变形将面罩本体夹持于用户的下颌。由此，将单一鼻部夹持条改进为上下双夹持条设计，可通过第一可变形夹持条和第二可变形夹持条的各自变形，既压紧用户鼻部，又压紧用户下颌部，提高面罩本体整体的密合性，进而提升了防护效果，与现有技术相比具有显著的进步。In the present invention, one of the first deformable clamping strip and the second deformable clamping strip is configured to clamp the mask body to the nose of the user through deformation, and the first deformable clamping strip and the second deformable clamp The other of the holding bars is configured to clamp the mask body to the chin of the user through deformation. As a result, the single nose clamping strip is improved to the upper and lower double clamping strips design, and the first deformable clamping strip and the second deformable clamping strip can be deformed separately to not only compress the user's nose, but also compress it. The lower jaw of the user improves the adhesion of the mask body as a whole, thereby improving the protective effect, which is a significant improvement compared with the prior art.
进一步地，由于第一可变形夹持条外置于第一焊接区段，第二可变形夹持条从第一部分跨过第三段中心线并延伸到第二部分，第一焊接区段延伸到面罩本体的第一边缘，第一焊接区段长度为6.3-6.9cm，第二焊接区段长度为6.2-6.8cm，第二焊接区段与面罩本体的第二边缘的距离为5.5-6.1cm，第一边缘和第二边缘为上下相对的两侧的边缘。特定长度的设计，使得呼吸装置可分别适合不同脸型佩戴，增加不同脸型用户的选择。如对于中庭长度大于下庭长度、或鼻部长度较长的脸型，可将第一段中心线及第一可变形夹持条向上佩戴，作用于用户的鼻部，此时第三段中心线及第二可变形夹持条向下佩戴，作用于用户的下颌部，实现最佳的密合性和舒适度。对于中庭长度小于下庭长度、或鼻部长度较短的脸型，包括儿童，可将第一段中心线及第一可变形夹持条向下佩戴，作用于用户的下颌部，此时第三段中心线及第二可变形夹持条向上佩戴，作用于用户的鼻部，实现最佳的密合性和舒适度。由此，基于本发明的呼吸装置，可通过变更佩戴方向，分别实现最佳的密合性和舒适度。Further, since the first deformable clamping bar is placed outside the first welding section, the second deformable clamping bar crosses the center line of the third section from the first section and extends to the second section, and the first welding section extends To the first edge of the mask body, the length of the first welding section is 6.3-6.9cm, the length of the second welding section is 6.2-6.8cm, and the distance between the second welding section and the second edge of the mask body is 5.5-6.1 cm, the first edge and the second edge are the edges on the opposite sides of the upper and lower sides. The design of a specific length makes the breathing device suitable for different face shapes, increasing the choices of users with different face shapes. If the length of the atrium is longer than the length of the lower court, or the length of the nose is longer, the first section of the centerline and the first deformable clamping strip can be worn upwards to act on the user’s nose. At this time, the third section of the centerline And the second deformable clamping strip is worn downward and acts on the user's jaw to achieve the best fit and comfort. For faces whose atrium length is less than the lower court length or the nose length is short, including children, the first section of the center line and the first deformable clamping strip can be worn downward to act on the user’s lower jaw. At this time, the third The segment centerline and the second deformable clamping strip are worn upwards and act on the user's nose to achieve the best fit and comfort. Therefore, the breathing apparatus based on the present invention can achieve the best adhesion and comfort by changing the wearing direction.
进一步地，由于第一段中心线与第二段中心线之间的夹角为120°-140°，第三段中心线与第二段中心线之间的夹角为130°-150°，第一可变形夹持条外置于第一焊接区段。由此，第一焊接区段有助于支撑保持面罩鼻腔处的立体结构，且三段中心线之间的特定角度范围设置与第一焊接区段、第二焊接区段具有联动配合效果，更符合人体工学设计，改善了面罩对各种脸型可能造成的口鼻部压迫性，且面罩本体密合保护性更好。而且，在外置的第一可变形夹持条和第一焊接区段的配合作用下，当拉紧带体组件时，第一可变形夹持条不容易变形，进而更有效密封鼻部，防护效 果更好。Further, since the angle between the centerline of the first section and the centerline of the second section is 120°-140°, the angle between the centerline of the third section and the centerline of the second section is 130°-150°, The first deformable clamping strip is placed outside the first welding section. As a result, the first welding section helps to support and maintain the three-dimensional structure of the nasal cavity of the mask, and the setting of the specific angle range between the three centerlines has a linkage effect with the first welding section and the second welding section, and more The ergonomic design improves the pressure of the mouth and nose that the mask may cause to various face shapes, and the mask body has better tightness and protection. Moreover, under the cooperation of the outer first deformable clamping strip and the first welding section, when the belt assembly is tightened, the first deformable clamping strip is not easily deformed, thereby more effectively sealing the nose and protecting Better results.
由于面罩本体的第三段中心线处为无焊接区段的圆滑过渡连接，当第一可变形夹持条作用于用户鼻部、第二可变形夹持条作用于用户下颌时，可以更好的贴合下颌部皮肤，解决下颌缝合线的设置造成的下颌不贴合问题，改善下颌密合性。Since the centerline of the third section of the mask body is a smooth transition without welding section, it can be better when the first deformable clamping strip acts on the user’s nose and the second deformable clamping strip acts on the user’s jaw. It fits the skin of the mandible, solves the problem of non-fitting of the mandible caused by the setting of the mandibular suture, and improves the tightness of the mandible.
