Example 1

Referring to fig. 1, the present embodiment provides a respiratory mask, including:

a mask body 10, the edge of which is provided with a support assembly 30 attached to the face 20;

a first light source 40, disposed on the support assembly 30, for photo-sterilizing the inner wall of the mask body 10.

and an adjusting mechanism for adjusting the position of the mounting mechanism to adjust the light emitting direction of the first light source 40, so that the first light source 40 can respectively irradiate the edge portion and the middle portion of the inner wall of the mask body 10.

Specifically, the mounting mechanism includes:

a support 31 disposed along an edge of the mask body 10; the support 31 is formed with a mounting groove 51 facing the mask interior; the supporting member 31 is a hard plastic member or a rubber member having a certain flexibility;

a plurality of spacer bars 52 connected to both side walls of the installation groove 51; the plurality of spacer bars 52 are arranged along a first direction, and the first direction is an extending direction of the mounting groove 51; i.e. the first direction is the direction of extension of the edge contour of the mask body 10.

A connecting rod 53 located in the mounting groove 51 and extending in the first direction; the connecting rod 53 is limited in the mounting groove 51 by the spacing bar 52; the connecting rod 53 is a deformable rubber member;

a plurality of mounting frames 54 rotatably mounted on the connection rod 53 in a first direction; the connecting rod 53 is a closed loop structure providing a rotational axis for rotation of the mounting bracket 54; at least one mounting bracket 54 is disposed between each two adjacent spacer bars 52.

Due to the setting of the adjustment mechanism, the first light source 40 has two states:

edge disinfection state:

as shown in fig. 4, the first light source 40 irradiates only the edge portion of the inner wall of the mask body;

middle part disinfection state:

as shown in fig. 5, when the adjusting member 62 is pressed to enter the adjusting groove 61, the end of the adjusting rod 62 presses the mounting bracket 54 toward the middle of the mask body so that it rotates around the connecting rod 53, and presses the elastic supporting portion 32-1 of the flexible liner 32, so that the first light source 40 rotates toward the center of the mask body, thereby achieving light sterilization of the middle of the inner wall of the mask body.

As shown in fig. 4 and 5, the hatched portions of the inner wall of the mask body 10 are schematic views of the irradiation area of the first light source 40 on the inner wall of the mask body in two states, respectively; as can be seen from the changes in the light irradiation areas in fig. 4 to 5, the adjustment mechanism realizes the changes in the irradiation areas on the inner wall of the mask body; the switching in the two states realizes the large-scale disinfection of the inner wall of the mask body.

When the hand-held rib 62-1 pulls the regulating member 63 out of the regulating groove 61, the regulating lever 62 releases the pressing force to the mounting bracket 54, so that the elastic supporting portion 32-1 is restored to the edge sterilizing state. Wherein the side walls of the adjusting member 63 and the adjusting groove 61 are respectively provided with a micro-protrusion and a micro-groove, so that the adjusting member 62 can be limited in the adjusting groove 61 and can be pulled out from the adjusting groove 61 by using external force.

The caregiver thus inserts or withdraws the adjustment member 63 into or from the adjustment slot 61 at intervals to effect the switching of the two light sterilization states.

In this embodiment, the adjusting rod is bent, and the end of the adjusting rod is bent towards the bottom of the mounting groove 51, so that the extrusion point of the adjusting rod 62 to the mounting frame 54 is close to the connecting rod, and a larger rotation angle of the mounting frame 54 can be achieved under the same displacement of the adjusting rod 62.

The embodiment realizes the sterilization of a larger area of the inner wall of the breathing mask.
