[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a light alarm device for an air respirator.

[0026] Example 1

[0027] The utility model provides Figure 1-3 The air respirator optical alarm device shown comprises a respirator mask 1 and an air pipe 2 connected to the lower end of the respirator mask 1, an electronic pressure alarm 3 is connected to the wall of the air pipe 2, a fixing box 4 is fixedly provided on the outer wall of the respirator mask 1, a sealing block 20 is fixedly provided on the outer wall of the fixing box 4 through a connecting belt 19, the sealing block 20 is a rubber block and is embedded with the inner wall of the fixing box 4, a rotating rod 5 is rotatably provided on the inner wall of the fixing box 4, a vertical pipe 6 is fixedly provided on the rod wall of the rotating rod 5, an optical alarm 7 is fixedly provided on the bottom of the vertical pipe 6, a plurality of indicator lights 8 are connected to the side wall of the optical alarm 7, a plurality of light guide columns 9 corresponding to the indicator lights 8 are fixedly provided on the inner wall of the vertical pipe 6, a plurality of color indicator labels 18 arranged at intervals are bonded to the outer wall of the vertical pipe 6, and the color indicator labels 18 are arranged corresponding to the indicator lights 8, and a cable 10 is connected between the optical alarm 7 and the electronic pressure alarm 3;

[0028] The side wall of the fixing box 4 is provided with a strip-shaped rotating hole, the vertical pipe 6 is slidably arranged in the strip-shaped rotating hole, and the outer wall is fixedly sleeved with a rubber cover 11, which is fixedly arranged outside the strip-shaped rotating hole.

[0029] When the respirator is in use, the electronic pressure alarm 3 is connected to the trachea 2 of the respirator, so that the gas pressure inside the trachea 2 can be monitored in real time. The cooperation of the optical alarm 7 and the indicator light 8 can provide alarm indications of different colors under different gas pressures. Therefore, when the respirator is in use, the corresponding indicator light 8 lights up, and the color is transmitted through the light guide column 9 at the corresponding position above it, and the corresponding color indicator label 18 on the outside of the vertical tube 6 is displayed at the same time, so that the user can be given accurate and effective optical alarm indications, which improves the use effect and safety of the respirator. Even people who are not sensitive to light can accurately judge the gas pressure inside the respirator at this time.

[0030] Example 2

[0031] Embodiment 2 is based on Embodiment 1 to reduce the irritation of the indicator light to the user's eyes. Figure 1-2 As shown, a mounting plate 12 is fixedly arranged on the inner wall of the fixed box 4, a DC motor 13 is fixedly arranged on the bottom of the mounting plate 12, an output end of the DC motor 13 passes through the mounting plate 12 and is fixedly provided with a reciprocating screw rod 14, a rack 15 is threadedly sleeved on the rod wall of the reciprocating screw rod 14, a gear 16 is meshed with the rack 15, and the gear 16 is fixedly sleeved on the outer side of the rotating rod 5, a sliding hole is opened inside the rack 15, a guide plate 17 is slidably penetrated inside the sliding hole, and the cross section of the guide plate 17 is L-shaped, and the guide plate 17 is fixedly connected to the inner wall of the fixed box 4.

[0032] When the respirator is in use, the DC motor 13 is started to drive the reciprocating screw 14 to rotate. During this process, the rack 15 can be driven by the reciprocating screw 14 to move stably longitudinally through the sliding of the guide plate 17 and the sliding hole, so that the rack 15 can engage with the gear 16, so that the rotating rod 5 drives the vertical tube 6 and multiple light guide columns 9 to swing. While the indicator light can be displayed to the user, the time that the light irradiates the user's eyes is reduced, thereby improving the use effect of the respirator alarm device.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
