Description

Ventilation device for mask

This disclosure relates to a mask ventilation device that can take measures against heat by lowering the temperature of the space between the mask body and the face with a simple configuration when using a disposable mask.

Masks are widely used to prevent pathogens and dust from entering the body with breathing, and to prevent secretions from the mouth and nose from being scattered around. In recent years, many products have been proposed because they are also effective in preventing pollinosis. For example, a mask (see, for example, Patent Document 1) in which a covering portion covering the mouth and an ear hook portion extending rearward from the covering portion are integrally formed by using an elastic sheet such as a non-woven fabric, or a rectangular shape. A mask that secures a breathing space between the mask body and the face by providing creases that are folded along the long side of the mask body (see, for example, Patent Document 2). Etc. are known.

As described above, the mask 1 is a pleated type mask, and the front surface of the mask main body 2 has a pleated shape. By spreading the pleats vertically and attaching the mask to the person 100, the mask main body 2 and the snout portion A space between the 102 and 102 is created, which makes breathing easier and makes it difficult to shift even when talking with the mask 1 on.

The mask ventilation device 10 has

ventilation units

11a and 11b arranged on both the left and right

side edge portions

2a and 2b of the mask main body portion 2, respectively, and a connection portion 12 connecting between the

ventilation units

11a and 11b. The connecting portion 12 connects the

ventilation units

11a and 11b along the rear surface of the mask main body portion 2, that is, the face side surface. As will be described later, the

ventilation units

11a and 11b function as a mask ventilation device as a single unit, but here, the mask ventilation device having two

ventilation units

11a and 11b connected via the connecting portion 12. 10 will be described.

Mounting portions 21 are provided on the upper and lower side surfaces of the

ventilation units

11a and 11b, respectively. The mounting portion 21 is mounted so that the main body portion 20 of the

ventilation units

11a and 11b is sandwiched between the

side edge portions

2a and 2b and the face 101. The mounting portion 21 is a clip of a rod-shaped member extending along the upper and lower side surfaces of the main body portion 20, and sandwiches the

side edge portions

2a and 2b between the upper and lower side surfaces of the main body portion 20. The

<Detailed configuration>
FIG. 4 is a front view showing the configuration of the mask ventilation device 10 before being attached to the mask 1. FIG. 5 is a plan view of the mask ventilation device 10 shown in FIG. FIG. 6 is a back view of the mask ventilation device 10 shown in FIG. FIG. 7 is a perspective view of the mask ventilation device 10 shown in FIG. 4 as viewed diagonally to the right and rear of the back surface side. FIG. 8 is a left side view of the mask ventilation device 10 shown in FIG. FIG. 9 is an exploded perspective view of the ventilation unit 11a. FIG. 10 is a sectional view taken along line AA of the ventilation unit 11a shown in FIG.

As shown in FIGS. 4 to 10, the

ventilation units

11a and 11b are connected by the connecting portion 12. The connecting portion 12 is, for example, a flexible binding band, and both ends thereof are latched by the latch structure 27 of each of the

ventilation units

11a and 11b. The latch structure 27 is a linear protrusion 26 formed in an insertion hole 25 formed on the upper surface (plane in the + Z direction) of the cover 20a engaged with the lower main body portion 20b. The connecting portion 12 is continuously formed with a linear groove that engages with the linear projection 26. Therefore, the length of the connecting portion 12 can be adjusted and held to a desired length. The insertion hole 25 communicates with the insertion hole 24 formed in the lower main body portion 20b to form one insertion hole. The connection portion 12 will be inserted into the insertion holes 24 and 25. As shown in FIG. 5, the upper surface of the cover 20a is inclined so that the height in the Z direction decreases toward the X direction, and when the protrusion of the tip portion of the connection portion 12 becomes long, the tip portion is inserted. Protrusion from the hole 25 is allowed.

By connecting the

ventilation units

11a and 11b using the connection portion 12, the

ventilation units

11a and 11b can be reliably attached to the mask main body portion 2 and the positions of the

ventilation units

11a and 11b are displaced. Can be prevented.

The connection portion 12 connecting the

ventilation units

11a and 11b is bent or maintained in a curved state so as to secure a space between the mask main body portion 2 and the face 101, and the ventilation unit 11a, from the snout portion 102. It prevents the mask main body 2 from obstructing the flow of exhaust gas to 11b.

As shown in FIG. 9, the ventilation unit 11a (11b) is formed by connecting the cover 20a to the lower main body portion 20b from the + X direction side.

The lower main body 20b is formed with an inclined plate that becomes lower in the X direction. An exhaust valve 40 as a ventilation mechanism is formed on this inclined plate. An opening 41 is formed in the inclined plate, and a valve body 42 capable of closing the opening 41 from above (+ Z direction) is arranged. One end of the valve body 42 is fixed by the mounting portion 43.

The valve body 42 is a sheet made of a flexible material having a certain degree of rigidity, such as polypropylene or polyester having a thickness of about 0.1 mm. One end of the valve body 42 may not be fixed by the mounting portion 43, but may be attached with double-sided tape so that it can be attached and detached. If the valve body 42 is removable, the valve body 42 may be replaced. Even when the

ventilation units

11a and 11b are fixed by the mounting portion 43, the

entire ventilation units

11a and 11b can be washed (washed with water), so that the valve body 42 can be washed at the same time as the

ventilation units

11a and 11b.

In each of the

ventilation units

11a and 11b, a ventilation passage L1 is formed between the opening 30 on the snout 102 side (-X direction side) and the opening 31 on the external side (+ X direction side). The opening forming the exhaust valve 40 is provided in the ventilation passage L1. The exhaust valve 40 enables only exhaust from the snout 102 side to the outside side.

When the internal pressure between the mask main body 2 and the face 101 becomes high due to exhalation, convection occurs in the mask main body 2, and as shown in FIG. 10, the valve body 42 bends the valve body 42'. Then, the exhaust valve 40 opens and is exhausted through the ventilation path L1 as shown by the arrow. After that, when the internal pressure becomes low, the valve body 42 closes the opening 41 and the ventilation passage L1 is shut off.

Due to the exhaust caused by opening the exhaust valve 40, an air flow is generated in the space between the mask main body 2 and the face 101. At this time, water droplets due to stuffiness are generated in the mask main body 2 due to continuous breathing, and the facial temperature is lowered by the heat of vaporization generated by the air flowing on the surface of the water droplets. Due to this decrease in the temperature of the face 101, measures against human heat (measures against heat stroke) will be taken. When wearing glasses, the amount of exhaust from the upper part of the mask is suppressed, so that the fogging of the glasses can also be suppressed.

As shown in FIG. 8, the bottom surface of the mounting portion 21 is floated by the thickness d of the mask main body portion 2 with respect to the bottom surface S of the main body portion 20. As a result, even when the

ventilation units

11a and 11b are attached to the mask main body 2, the bottom surface S of the main body 20 and the surface of the mask main body 2 on the face 101 side are substantially flush with each other to prevent the mask. The filter functions such as bacteria and dustproof are not impaired.

FIG. 11 is a perspective view of the ventilation unit 11a as viewed from the back surface side. As shown in FIG. 11, the bottom surface S of the ventilation unit 11a (11b) has a U-shape and is in contact with the face 101 so that the contact area with the face 101 is reduced. The portion that comes into contact with the face 101 is only the bottom surface S of the frame that stands in the Z direction. This does not give a sense of discomfort when the

ventilation units

11a and 11b are attached. Since the face 101 forms a part of the ventilation path L1, it is possible to promote a temperature drop due to ventilation to the face 101, which is a mounting portion of the

ventilation units

11a and 11b.

According to the mask ventilation device 10 of the first embodiment, it is possible to take measures against heat with a simple structure using the exhaust valve 40. Even if the mask is disposable, the mask ventilation device 10 can be used repeatedly for each mask. The comb-shaped clip structure makes it easy to attach / detach the mask ventilation device 10 to / from the mask main body 2.
