Example 2

[0032] Based on Example 1, a preferred embodiment of the detachable explosion-proof electric safety helmet provided by the present invention is as follows: Figures 1 to 5 As shown: the ventilation component 6 includes a ventilation box 602, which is fixedly connected to the middle position of the lower end of the back side of the safety helmet body 1, a battery compartment 604 is fixedly connected to one side of the ventilation box 602, a micro fan 607 is fixedly connected to the inner wall of the ventilation box 602, a fixing groove 608 is provided on the top of the ventilation box 602 away from the micro fan 607, a clamping plate 609 is rotatably connected to the top of the ventilation box 602 on one side of the fixing groove 608, a fixing plate 603 is movably connected to the top of the ventilation box 602, a reserved groove 606 is provided on one side of the fixing plate 603, and a filter screen 601 penetrating the fixing groove 608 is fixedly connected to the bottom end of the fixing plate 603, by starting the micro fan 607, the external fresh air is filtered through the filter screen 601 and sucked into the ventilation box 602, and then transported to the inside of the safety helmet body 1, and then flows out from the front through hole of the safety helmet body 1 and the gap between the safety helmet body 1 and the worker, thereby accelerating the air flow inside and outside the safety helmet body 1 and realizing ventilation and heat dissipation in the head area of ​​the worker.

[0033] In this embodiment, a snap-fit ​​structure is formed between the filter 601 and the interior of the ventilation box 602. The lower end of the filter 601 is semicircular. The snap-fit ​​between the filter 601 and the ventilation box 602 ensures that the filter 601 will not shake back and forth after being snap-fitted and installed.

[0034] In this embodiment, the cross-section of the reserved slot 606 is rectangular, and the reserved slot 606 and the clamping plate 609 are both in the same horizontal plane. The rectangular reserved slot 606 allows the clamping plate 609 to only rotate away from one side of the reserved slot 606 .

[0035] In this embodiment, a rubber sheet 605 is fixedly connected to one end of the inner top wall and the inner bottom wall of the reserved groove 606. The cross-section of the rubber sheet 605 is a right-angled trapezoid. The right-angled convex rubber sheet 605 makes it easier for the card plate 609 to rotate toward the inner side of the reserved groove 606, and the deformation of the rubber sheet 605 itself will increase the tightness of the card plate 609 and the inner wall of the reserved groove 606, thereby preventing the card plate 609 from accidentally rotating away and affecting the stability of the fixed plate 603.

[0036] The working principle and use process of the utility model are as follows: first, the worker wears the helmet body 1 and locks it with the fixing rope 5, then rotates the explosion-proof mask 2 downward to protect the worker's face. When the explosion-proof mask 2 is not needed, it can be rotated upward. At the same time, when wearing the helmet body 1 in hot weather, the worker can press the switch button on the side of the battery compartment 604 to start the micro fan 607, and then the external fresh air is sucked into the ventilation box 602, and filtered through the filter 601 to prevent large particles of impurities from being sucked in. After that, the fresh air enters the helmet body 1, and then passes through the front through-hole of the helmet body 1 and the helmet body. The air flows out from the gap between the helmet body 1 and the worker's wearing, speeding up the air flow inside and outside the helmet body 1, realizing ventilation and heat dissipation in the head area of ​​the worker, and avoiding the feeling of dampness caused by long-term wearing. At the same time, the card plate 609 can be rotated from time to time to be completely separated from the inside of the reserved groove 606, and then the filter 601 can be taken out from the inside of the ventilation box 602 through the fixed plate 603, which is convenient for cleaning and preventing the filter 601 from being blocked. After the subsequent installation, the card plate 609 can be stuck to the inside of the reserved groove 606, and the rubber sheet 605 can be used to ensure the clamping of one end of the card plate 609 with one side of the inner wall of the reserved groove 606, so as to avoid the card plate 609 from accidentally rotating away and affecting the stability of the fixed plate 603 limit.

[0037] When the surface of the explosion-proof mask 2 is severely scratched or damaged, the sliding block 306 can be driven to slide by pulling the pull rod 301, so that the mounting block 308 slides to completely disengage from the inside of the mounting hole 303, and then the explosion-proof mask 2 is pulled upward to make the clamping block 302 completely disengage from the inside of the clamping slot 307 to achieve disassembly. During installation, the pull rod 301 is first pulled to make the mounting block 308 slide to the inside of the mounting slot 305, and then the clamping block 302 is clamped into the inside of the clamping slot 307 to achieve preliminary clamping and fixation of the explosion-proof mask 2, and then the pull rod 301 is released, and the elastic force of the installation spring 304 is used to make the mounting block 308 slide to the inside of the mounting hole 303, so as to achieve limited fixation of the clamping block 302 and the inside of the clamping slot 307, thereby achieving rapid disassembly and assembly between the explosion-proof mask 2 and the rotating frame 4, which is convenient for replacing the explosion-proof mask 2 that is severely scratched or damaged.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
