Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

Referring to Figures 1 to 3, a fire escape helmet structure includes a front cover 1, a filter elastic cloth 2 and a rear cover 3 connected in sequence, the front cover 1, filter elastic cloth 2 and the rear cover The bottom of the shell 3 is provided with a bottom tightening mesh cloth 4, the inside of the front cover 1 is provided with a front pre-storage water tank 5, the middle part is provided with a transparent window 6, and a nose-end protruding cover is provided below the transparent window 6 7. The filter elastic cloth 2 is provided with two ear-avoiding collars 8 , and the rear pre-storage water tank 9 is provided inside the rear cover 3 .

Further, a front cover water inlet and outlet button 501 is provided on the shell below the top of the front pre-storage water tank 5, and a front cover slow water seepage button 502 is provided on the bottom shell. After the front cover water inlet and outlet button 501 is pressed, It has a large amount of water discharge or water filling function. After the slow seepage water button 502 of the front cover is pressed, the water will slowly seep out through gravity.

Further, the inner side of the ear avoiding collar 8 is provided with ear avoiding collar soft glue 10, so that the ear avoiding collar 8 is close to the head.

Further, the bottom shell of the rear pre-storage tank 9 is provided with a rear cover water inlet and outlet button 901 , and the bottom shell is provided with a rear cover slow seepage water button 902 . The water inlet and outlet button 901 of the rear cover has a large amount of water discharge or water filling function after being pressed, and the slow water seepage button 902 of the rear cover is pressed to make water slowly seep out through gravity.

Further, the front cover water inlet and outlet button 501, the front cover slow seepage water button 502, the rear cover water inlet and outlet button 901 and the rear cover slow seepage water button 902 are all set in pairs, and there are settings on the left and right sides , and are all directly connected with the filter elastic cloth 2.

Further, the appearance color of the fire escape helmet is set to a cool color such as blue and green, highlighting the color difference from the fire scene.

Further, the bottom tightening mesh 4 is fastened in the middle of the mouth, which does not affect shouting.

Referring to Fig. 5, further, the bottom tightening mesh 4 is provided with a bottom mesh tightening rope 11, and the bottom tightening mesh 4 is flush with the mouth, which is convenient for shouting at the fire scene.

The working principle of this embodiment is as follows:

During use, the fire escape helmet is worn on the head, and the bottom net tightens the rope 11 to tighten it in the mouth, which does not affect people's shouting for help and communication. The ears are located in the ear escape collar 8, so that sensitive hearing and eyes can be maintained The surrounding environment can be observed from the transparent window 6, which protects the eyes and maintains a good field of view, then opens the rear cover water inlet and outlet button 901 and the front cover water inlet and outlet button 501 to make a large amount of water flow out, and quickly soak the filter elastic cloth 2 and The bottom tightens the mesh cloth 4, so that the air to breathe will enter from the moist filter elastic cloth 2 and the bottom tightened mesh cloth 4 to achieve a good filtering effect. People breathe through the filter breathing channel 12, as shown in Figure 4 Show. Next, open the slow seepage water button 502 of the front cover and the slow seepage water button 902 of the rear cover. Through the functions of the two buttons, the water will slowly penetrate into the filter elastic cloth 2 and the bottom tightening mesh cloth 4, even if it is filtered by the outside When the heat evaporates, it can also replenish water in time to keep it moist. Therefore, there is no need to look for another water source, and there is no need to worry about choking on toxic fumes. The cool-toned helmet color not only highlights the difference with the environment color, it is easy to be found, but also has a calming effect, which is helpful for people to find escape routes as soon as possible.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
