<Detailed composition>

FIG. 4 is a front view showing the structure of the ventilation device 10 for a mask before being installed on the mask 1. Fig. 5 is a plan view of the ventilation device 10 for a mask shown in Fig. 4. Fig. 6 is a back view of the ventilation device 10 for a mask shown in Fig. 4. In addition, FIG. 7 is a perspective view when the ventilation device 10 for a mask shown in FIG. 4 is viewed diagonally from the back side to the right. Fig. 8 is a left side view of the ventilation device 10 for a mask shown in Fig. 4. In addition, FIG. 9 is an exploded perspective view of the ventilation unit 11a. Fig. 10 is a sectional view taken along the line A-A of the ventilation unit 11a shown in Fig. 8.

As shown in FIGS. 4 to 10, the ventilation units 11 a and 11 b are connected by the connecting portion 12. The connecting portion 12 is, for example, a flexible strap, and both ends are connected by the latch structures 27 of the ventilation units 11a and 11b. Come to the latch. The latch structure 27 is a linear protrusion 26 formed in the through hole 25 formed on the upper surface (+Z direction) of a cover 20a engaged with the lower body portion 20b. In the connecting portion 12, a linear groove engaged with the linear protrusion 26 is continuously formed. Therefore, the length of the connecting portion 12 can be adjusted to a desired length and maintained. The through hole 25 communicates with the through hole 24 formed in the lower body portion 20b to form a through hole. The connecting portion 12 penetrates through the through holes 24 and 25. In addition, as shown in FIG. 5, the upper surface of the cover 20a is inclined such that the height in the Z direction decreases toward the X direction. When the protrusion of the front end of the connecting portion 12 becomes longer, the front end is allowed to pass from the through hole. 25 outstanding.

By connecting the ventilation units 11a and 11b using the connecting portion 12, the ventilation units 11a and 11b can be reliably attached to the mask body 2 and the positional deviation of the ventilation units 11a and 11b can be prevented.

Furthermore, the connecting portion 12 connecting the ventilation units 11a, 11b is bent to ensure a space between the mask body 2 and the face 101, or to maintain a curved state to prevent the mask body 2 from obstructing the mouth The nose 102 faces the flow of exhaust from the ventilation units 11a, 11b.

In addition, as shown in FIG. 9, the ventilation unit 11a (11b) is formed by joining the cover 20a to the lower body part 20b from the +X direction side.

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

The valve body 42 is, for example, a sheet formed of a flexible material having a certain degree of rigidity such as polypropylene or polyester with a thickness of about 0.1 mm. In addition, one end of the valve body 42 can also be set not to be fixed by the mounting portion 43, but to be detachably attached with a double-sided adhesive. In addition, when the valve body 42 The valve body 42 may be replaced for ease of disassembly and assembly. However, when the valve body 42 is fixed by the mounting portion 43, the entire vent units 11a and 11b can be cleaned (washed with water), so the valve body 42 can be cleaned at the same time.

The ventilation units 11a and 11b each have a ventilation path L1 formed between the opening 30 on the snout 102 side (the −X direction side) and the opening 31 on the outside (+X direction side). The opening of the exhaust valve 40 is provided in the air passage L1. The exhaust valve 40 can only exhaust air from the snout 102 side to the outside.

That is, when the internal pressure between the mask body 2 and the face 101 becomes high due to exhalation, convection will be generated in the mask body 2, and as shown in FIG. 10, the valve body 42 becomes flexed. In the valve body 42', the exhaust valve 40 is opened, and as indicated by the arrow, exhaust is exhausted through the air passage L1. After that, when the internal pressure becomes low, the valve body 42 closes the opening 41, and the air passage L1 is blocked.

Due to the exhaust caused by the opening of the exhaust valve 40, a flow of air occurs in the space between the mask body 2 and the face 101. At this time, water droplets caused by sultry heat are generated in the mask body 2 due to continuous breathing, and the face temperature is reduced due to the heat of vaporization generated by the air flowing on the surface of the water droplets. With this reduction in the temperature of the face 101, a person's countermeasures against heat (heatstroke countermeasures) are sought. In addition, when wearing glasses, by suppressing the amount of exhaust from the upper part of the mask, fogging of the glasses can also be suppressed.

In addition, as shown in FIG. 8, the bottom surface of the mounting portion 21 floats relative to the bottom surface S of the main body portion 20 by an amount corresponding to the thickness d of the mask main body portion 2. Thereby, even when the ventilation units 11a, 11b are installed on the mask body 2, the bottom surface S of the body 20 and the face 101 side of the mask body 2 will become substantially flush without damage The mask has filter functions such as anti-bacterial or dust-proof.

Fig. 11 is a perspective view of the ventilation unit 11a when viewed from the back side. As shown in Fig. 11, the bottom surface S of the ventilation unit 11a (11b) is configured to contact the face 101 in a U shape, and the area that contacts the face 101 is reduced. That is, the part contacting the face 101 is only the bottom surface S of the frame standing in the Z direction. Thereby, when the ventilation units 11a, 11b are installed, there will be no sense of disharmony, and since the face 101 forms the ventilation path L1 Part of it, therefore, it is possible to promote a decrease in temperature caused by ventilation with respect to the face 101 belonging to the installation part of the ventilation unit 11a, 11b.

In this embodiment, it is possible to counteract heat by using the simple structure of the exhaust valve 40. In addition, even disposable masks can be reused in each mask. Furthermore, the comb-shaped clamp structure makes it easy to detach and assemble the mask body 2.
