Description

Mask capable of treating condensed water

Technical Field

The invention relates to the technical field of medical care appliances, in particular to a mask capable of treating condensed water.

Background

The traditional medical surgical mask body has a three-layer structure from outside to inside, and comprises a first breathable water-repellent non-woven fabric layer, a filter layer and a second breathable water-repellent non-woven fabric layer in sequence. After medical personnel wear the gauze mask for a long time, a large amount of condensed water appears in the gauze mask, especially in the region with large temperature difference, the exhaled gas is instantly liquefied into condensed water, even can be frozen, not only can cause the uncomfortable feeling of wearing, but also can influence the protective effect of the gauze mask.

In addition, the existing one-way moisture-conducting fabric is basically characterized in that a hydrophilic coating, a waterproof coating, a water-repellent coating and the like are carried out on a knitted fabric, the fabric is required to be treated by chemical reagents, the number of layers of the fabric which can achieve the one-way moisture-conducting function is large, the ventilation function is poor, and a mask applying the fabric for a long time is easy to generate oxygen deficiency.

Therefore, how to provide a mask capable of treating condensed water is a technical problem that needs to be solved urgently by those skilled in the art.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1, a mask for treating condensed water includes: the filter comprises a hydrophilic hydrophobic inner layer 1, a filtering one-way diversion middle layer 2 and a hydrophobic outer layer 3 which are arranged from inside to outside in sequence. The hydrophilic and hydrophobic inner layer 1 mainly plays a role in quickly absorbing water, and the filtering one-way diversion middle layer 2 mainly plays a role in discharging condensed water. Refuse the inlayer and filter the middle level for traditional, can effectively with comdenstion water discharge gauze mask to and prevent the comdenstion water backward flow, thereby avoid the comdenstion water to store in the gauze mask, and then the influence wears the comfort level, also can avoid certainly that the gauze mask freezes, guaranteed the protective effect of gauze mask.

Specifically, the hydrophilic-hydrophobic inner layer 1 includes a water-repellent material 5 and a hydrophilic material 4 interposed within the water-repellent material 5. The water-repellent material 5 and the hydrophilic material 4 may be materials known in the art, and the present embodiment is manufactured by mixing two materials. As shown in fig. 2 and 3, the water-repellent material 5 is located inside, and the proportion of the hydrophilic material 4 located outside the water-repellent material 5 is greater than that of the hydrophilic material located outside the water-repellent material 5, that is, most of the hydrophilic material 4 is located outside the water-repellent material 5, so as to achieve the purpose of rapid drainage.

Specifically, the hydrophobic outer layer 3 is a hydrophobic heat-insulating outer layer, and the temperature of the exhaled air can be stored through the hydrophobic heat-insulating outer layer to reduce the temperature difference between the exhaled air and the mask, so that the generation of condensed water is reduced, as shown in fig. 7, the hydrophobic heat-insulating outer layer comprises a water-repellent layer and a heat-insulating material 7 arranged on the water-repellent layer.

As shown in fig. 4, the filtering unidirectional flow guiding middle layer 2 specifically includes a filtering layer and a unidirectional flow guiding structure 6 disposed on the filtering layer, the unidirectional flow guiding structure 6 is used for preventing water flow guiding when inhaling, as shown in fig. 5, when the unidirectional flow guiding structure 6 inhales, the airflow direction is as shown by an arrow in fig. 5, and at this time, the unidirectional flow guiding structure 6 is closed; as shown in fig. 6, the unidirectional flow guiding structure 6 is in the exhalation state, the air flow pattern 6 is shown by the arrow, and the unidirectional flow guiding structure 6 is opened.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
