Description

The present invention relates to mask assemblies, especially mask assemblies that can be used in combination with straws and filters.

The function of the mask is primarily to protect the respiratory tract and block harmful substances such as bacteria, viruses, toxic airborne particles (eg PM2.5) or chemicals in the environment. In the process of wearing the mask, the user's mouth and nose must be completely covered and sealed as much as possible to ensure that harmful substances are blocked outside the mask. However, it is necessary to remove the mask when trying to eat or drink during the process of use. This puts the user at risk of contamination. In particular, if you need to drink enough water a day and drink frequently (such as water), you will have to remove the mask many times during the process of wearing the mask. It is even more inconvenient for staff working in high-risk environments, especially medical staff at high risk of virus infection. Moreover, in order to provide good barrier properties, common masks are usually multi-layered. Taking a surgical mask as an example, it is mainly composed of waterproof fiber non-woven fabric, skin-friendly fiber non-woven fabric, and melt blow non-woven fabric. It makes a person uncomfortable.

Therefore, in order to improve the convenience of using the mask and improve the protection property, it is necessary to develop an improved mask assembly that can solve the defects of the prior art in the art.

The outline of the invention is intended to provide a simplified summary of the disclosure content so that the reader can understand the basics of the disclosure content. The outline of the present invention is not a complete outline of the disclosed contents, and its intention is not to point out the important / main elements of the embodiments of the present invention or to define the scope of the present invention.

To solve problems existing in the prior art, one aspect of the present invention relates to a new mask assembly. This assembly solves the inconvenience of wearing the mask for extended periods of time during the epidemic prevention period, especially the problem of drinking drinks and / or the poor breathability of the mask.

According to one embodiment of the present invention, the mask assembly can be used in combination with a straw and includes a first assembly tool, a second assembly tool and a puncture tool. Specifically, a through hole is provided inside the first assembly tool, a flange is provided outside, a male screw is provided above the flange, and a connecting portion is provided below. Female screws are provided in at least a part of the inside of the second assembly tool. The female screw and the male screw of the first assembly tool are screwed together. The puncture tool has a fitting portion and is connected to the through hole by the fitting portion. In the present invention, the mask body is punctured at an appropriate position using a puncture tool to form a perforation, then removed, and the second assembly tool is screwed into the first assembly tool and fixed to the perforation of the mask body. Connect to the straw through the through hole of the first assembly tool.

Further, according to another embodiment of the present invention, the mask assembly further includes a lid that is connected to the first or second assembly and seals the through hole.

According to another embodiment of the present invention, the mask assembly further includes a filter connected to a second assembly. As a result, the ventilation rate when wearing the mask is increased, and the suffocation of wearing the mask for a long time is eliminated. The filter includes an upper housing and a lower housing connected to each other, a storage space is formed between them, and a filtration sheet is provided in the storage space. Specifically, the upper housing is provided with a plurality of pores in the wall. The lower housing includes a connecting port, a check valve and a protrusion. This is because the connecting port is connected to the second assembly tool. The check valve is provided at the connecting port. The protrusion extends from the periphery of the connecting port toward the accommodation space. The filtration sheet is provided in the accommodation space. In any embodiment, the upper housing and the lower housing are connected by screwing, engaging or any suitable method known in the art.

In a non-limiting embodiment, the filtration sheet is capable of filtering fine particles of at least 2.5 μm or larger. In a preferred embodiment, the filtration sheet is capable of filtering fine particles of at least 0.1 μm or larger. Therefore, the filter can filter suspended fine particles in the air, for example, PM2.5 fine particles, and preferably can filter bacteria and viruses to block harmful substances out of the mask. Furthermore, in a preferred embodiment, the filtration sheet is made of graphene.

The mask suitable for this mask assembly may be each type of mask on the market. For example, examples of the mask include, but are not limited to, planar, C-shaped, shell-shaped, duck-billed or foldable. Further, the straws applied to the mask assembly may be commercially available disposable and non-disposable straws, preferably elastic plastic straws.

In the present invention, due to the above-mentioned unique new design, the mask assembly of the present invention can be applied to various existing masks, has the advantages of repeatability and durability, and even when the mask is worn, the mask assembly and the above-mentioned mask assembly If you can drink with a straw and do not need to eat or drink, use it in combination with a lid or filter to restore the integrity of the original mask, block external airborne particles or germs, and prevent epidemics.

Specifically, when the user exhales, the gas discharged through the filter 350 can be discharged to the outside of the mask, and a good exhaust effect can be achieved.

Furthermore, another aspect of the present invention relates to how to use the mask assembly 300. When the user assembles the mask assembly 300 of the present invention on the mask body 251, in an emergency situation where a fire breaks out, wet the mask and wet the mouth and nose to avoid inhaling too much smoke or carbon dioxide. Need to cover. However, wetting the mask makes it difficult to exhale. In this case, by providing the filter 350, the ventilation rate can be improved by the filter 350. As will be appreciated by those skilled in the art, the filter sheet 380 used in the filter 350 of the present invention may be made of other known filter material capable of blocking harmful chemicals. This makes it applicable even in dense smoke, carbon dioxide and high temperature environments.

The mask body applicable to the mask assembly according to the different embodiments of the present invention may be, but is not limited to, a planar, C-shaped, shell-shaped, duckbill-shaped or foldable commercially available mask.

Based on the above, the mask assembly according to the present invention solves the defects of the conventional mask, provides a better wearing experience in terms of drinking fluid substances and improving the ventilation rate, and reduces the inconvenience of repeatedly wearing the mask. Especially in situations where epidemic infectious diseases are prevalent, the number of repeated mask attachments and detachments is reduced, the risk of splash transmission between individuals is avoided, and the epidemic prevention failure due to eating and drinking is effectively prevented. Waste of medical resources is avoided.

Specific examples of the present invention have been disclosed in the above embodiments, but these examples are not limited to the present invention. Those skilled in the art may make various changes and modifications as long as they do not deviate from the principles and ideas of the present invention. Therefore, the scope of protection of the present invention should conform to the scope of claims for utility model registration.
