Description

Filter replacement mask {MASK OF FILTER REPLACEMENT TYPE}

The present invention relates to a filter replaceable mask, and more specifically, it is possible to easily put the filter inside the cover covering the mouth and nose, and when replacing the filter, it is characterized in that it is configured to easily withdraw the inserted filter It relates to a filter replaceable mask.

In general, the mask 1 is also used for cold protection, but in recent years it has become a necessity of life in order to prevent fine dust and infectious diseases. Hereinafter, the mask 1 will be described with reference to the accompanying drawings.

1 is a perspective view showing a mask according to the background art, and is described together.

The mask 1 is composed of a sheet-shaped cover 10 covering the nose and mouth and a string that is connected to both sides of the cover 10 in a U-shape and hooks on both ears of a person.

The cover 10 is made of various fabrics such as fabric or non-woven fabric as air can pass through when breathing. In addition, the cover 10 is composed of an outer sheet 11 facing the front and an inner sheet 13 facing the rear, that is, a person's face. Then, a filter (not shown) for filtering viruses or fine dust is disposed between the outer sheet 11 and the inner sheet 13. As such, the filter is interposable, and the filter is not configured to be reused by washing.

However, recently, the Corona 19 infection has been facing a great crisis not only in Korea but also worldwide. As the best way to block corona19 in the absence of a vaccine yet, experts suggest wearing a mask 1 and washing your hands.

However, hand washing is an easy practice and anyone can do it with will, but in the case of the mask 1, it is not easy to equip and wear it in a state where the amount of water is insufficient. Since the mask 1 is disposable and cannot be reused, it must be purchased each time, so the lack of the mask 1 is inevitable. And the economic burden of replacing and using a new one every day cannot be ignored. Of course, there are some that can be reused by sucking, such as cotton masks. However, since these do not have filters inside, it is impossible to filter particulates such as viruses and fine dust.

In the meantime, a method of inserting and using a filter between the outer sheet 11 and the inner sheet 13 of the reusable mask 1 has been suggested through media. This is to insert the filter after cutting the inner sheet 13 of the mask 1, and the filter can be replaced after use, thereby eliminating the hassle of purchasing the disposable mask 1 each time, and is economical. The burden can be reduced, and the filtration function is excellent because the filter uses an electrostatic filter.

However, there is a problem in that it is not easy to insert a filter having a flexible property between the inner sheet 13 and the outer sheet 11 of the mask 1. If the filter is plate-like having rigidity, it can be easily put in, but as a thin electrostatic filter fabric, it is easily dried when inserted, so there is a problem that there is no reality.

Therefore, people are forced to buy and wear disposable masks, and in this case, there is a problem that pollutes the environment due to the economical burden of purchasing every time, and the resources are wasted and the amount of garbage is increased because it is used once.

Hereinafter, a configuration of the filter replaceable mask 100 according to the present invention together with the accompanying drawings will be described.

Figure 2 is a filter replacement mask according to the present invention will be described together as a perspective view showing the process of connecting the filter to the filter to the inside of the cover.

A cover 110 formed to cover a person's mouth and nose is configured, and strings 121 and 123 connected in a U shape are formed on both sides of the cover 110 so as to be caught by a human ear.

The cover 110 is of a sheet shape and has flexibility to cover a person's mouth and nose. The cover 110 is configured with an outer sheet 111 facing forward, and an inner sheet 113 disposed behind the outer sheet 111 and, more specifically, on the person's face. The outer sheet 111 and the inner sheet 113 may be made of a flexible material such as woven paper or non-woven fabric.

In addition, a space is formed between both sides by attaching the edges of the outer sheet 111 and the inner sheet 113 to each other. Attachment of the rim is possible by rod or adhesive. The adhesion refers to adhesion by thermal adhesion or adhesive as an example.

In addition, an incision 115 formed in the vertical direction on one side of the left and right sides of the inner sheet 113 is configured. That is, as shown in FIG. 1, it may be arranged at a point biased to the left or may be arranged at a point biased to the right. Therefore, a space between the outer sheet 111 and the inner sheet 113 may be opened to the outside through the incision 115.

In addition, in the inner sheet 113, holes 117 respectively drilled up and down on the opposite side of the incision 115 are configured. That is, as shown in FIG. 1, it may be arranged at a point biased to the right, or may be arranged at a point biased to the left.

In addition, the strings 123 on one side of the strings 121 and 123 on both sides are configured such that both end portions 125 are fitted into the respective holes 117 from the outside of the inner sheet 113. At this time, the string 121 opposite the string 123 is fixed to the cover 110. And it is formed on the strap 123 on one side, the inner portion of the inner sheet 113, the engaging portion 127 is formed in the hole 117, as an example, by making a knot to make the engaging portion 127 can be configured . Therefore, unlike the fixed string 121 on the opposite side, the string 123 can be moved to the left and right, and when the string 123 is pulled outward to the end because the locking portion 127 is caught in the hole 117 It is configured to be prevented.

In addition, the filter 130 is formed to be inserted into the incision 115, it is a sheet shape of a flexible material, it is possible if it can filter out fine dust or viruses. As an example, it may be provided with an electrostatic filter fabric, preferably KF (Korea Filter) 80 or higher.

In addition, the filter 130 and the both ends of the string 123 is configured with a detachable means 140 configured to be detachable from each other. The detachable means 140 is formed as a hook 143 connected to the end 125 of the string 123 as an example, and a hole 145 drilled in the filter 130 to be caught by the hook 143 It is possible by. At this time, the hole 145 is biased toward the hook 143 and is disposed at the end of the filter 130.

In addition, when the filter 130 enters the incision 115, the film 147 formed in the portion where the hole 145 is formed is front or rear of the filter 130, or both sides, so as to maintain the expanded state. After they are all attached, the hole 145 is drilled in the film 147 and the filter 130 at the same time. Therefore, since the upper and lower portions of the filter 130 are rolled up and are not able to cope with the entire surface of the cover 110, it is possible to prevent a foreign matter such as fine dust or a virus from passing through.

3 is a perspective view showing an example in which the Velcro tape is configured as another embodiment of the detachable means configured in the filter replaceable mask according to the present invention, and looking at another example of the detachable means 140 as follows.

One side velcro tape 146 is configured to be connected to both end portions 125 of the string 123 at the same time, and the other side velcro tape 146 detachable from the one side velcro tape 146 is one of the filters 130 It is attached to the side. At this time, the opposite side velcro tape 148 is biased toward one side velcro tape 146 and disposed at the end of the filter 130.

Also, in this case, since the velcro tape 146 is caught in the hole 117, the locking portion 127 is not configured.

The use case of the filter replaceable mask 100 according to the present invention as described above will be described with reference to the accompanying drawings.

4 is a perspective view showing a state in which the filter is connected to the string in the state of FIG. 2, and shows an example in which the string 123 and the filter 130 are connected. That is, by inserting a finger inside the incision 115, the hook 143 is pulled out of the incision 115. At this time, the string 123 is to go inside the cover 110. In this way, the exposed hook 143 is caught in the hole 145 of the filter 130.

5 is a perspective view showing a state in which the filter is inserted into the cover by pulling the string in the state of FIG. 4, after the hook 143 is caught in the hole 145, the string 123 from the outside of the inner sheet 113 ) And pull outward. Then, the filter 130 connected to the string 123 is inserted between the inner sheet 113 and the outer sheet 111. At this time, the filter 130 by the film 147 is disposed inside the cover 110 in a stretched state without drying, so that smooth filtering is possible. Therefore, the filter 130 can be easily inserted into the inside of the cover 110 in an unfolded state. In addition, since the locking portion 127 is caught in the hole 117, the phenomenon that the string 123 deviates outward is prevented. In addition, it is of course that the string 123 functions to be caught in the ear together with the opposite string 121.

6 is a perspective view showing a process of drawing out the filter in the state of FIG. 5, when replacing the filter 130 after use, open the incision 115 and pick the filter 130 with a finger and pull it outward. Then, the string 123 also enters the inside of the cover 110 one after another. In this way, the filter 130 is detached from the hook 143 in the withdrawn state until the hook 143 is exposed. Next, the new filter 130 is accommodated in the cover 110 in the order presented through FIGS. 4 and 5. At this time, the filter 130 can be stored in the expanded state by the mating velcro tape 148 attached to the filter 130.

The detachable means 140 shown in FIG. 3, that is, both side velcro tapes 146 and 148, can be used through the above-mentioned procedure.

As described above, according to the present invention, the sheet-shaped cover 110 can be easily accommodated inside the cover 110 in an unfolded state. In addition, since it is accommodated in an unrolled, unfolded state, smooth filtering is possible as compared to entering a dried state. Therefore, by actually realizing the replacement of the filter 130, it is possible to relieve the economical burden of buying a disposable mask of KF 80 or more each time, and the disposable mask should be discarded entirely after use, but the present invention only replaces the filter 130 Since it can be done, it is possible to prevent waste of resources and to protect the environment by reducing the amount of waste.
