[0034] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0035] like Figures 1-3 As shown in the figure, a personal protective equipment for coal mines according to one embodiment of the present invention includes a helmet body 1, which has a hollow structure. A goggle 2 is fixedly installed on the helmet body 1, and a slide rail 201 and a protective lens 202 are fixedly installed on the goggle 2. The slide rail 201 and the protective lens 202 are tightly bonded to the goggle 2, ensuring their service life and preventing them from falling off, thus improving safety during work.

[0036] The goggles 2 are also equipped with a wiping assembly 3. The wiping assembly 3 has a hollow structure inside. The end face of the wiping assembly 3 near the goggles 2 is open. The wiping assembly 3 is equipped with a slider 302, which allows the wiping assembly 3 to slide on the slide rail 201.

[0037] like Figures 5-8 As shown, the wiping assembly 3 has a main shaft 3011 welded to its upper and lower parts inside. A rectangular opening is provided on one end face of the wiping assembly 3 away from the goggles 2. A sliding handle 301 is installed inside the wiping assembly 3, and a through hole is provided on the sliding handle 301. The main shaft 3011 passes through the through hole in the sliding handle 301, allowing the sliding handle 301 to rotate around the main shaft 3011 as its axis of rotation. Simultaneously, the sliding handle 301 protrudes from the outside of the wiping assembly 3 through the rectangular opening. The sliding handle 301 also has a raised cylindrical shape, making it easier for the user to operate and requiring less effort.

[0038] The wiping assembly 3 is also welded with a first rotating shaft 3031 and a second rotating shaft 3041 on the top and bottom. The wiping assembly 3 is equipped with a wiping scraper 303 and a wiping plate 304. The wiping scraper 303 has a through hole, and the first rotating shaft 3031 passes through the through hole on the wiping scraper 303. Therefore, the wiping scraper 303 can rotate around the first rotating shaft 3031 as the rotation axis.

[0039] The wiping plate 304 also has a through hole, and the second rotating shaft 3041 passes through the through hole in the wiping plate 304, so the wiping plate 304 can rotate around the second rotating shaft 3041 as the rotation axis. The wiping scraper 303 and the wiping plate 304 are tilted outward in a stationary state.

[0040] The wiping blade 303 and wiping plate 304 are connected to the wiping assembly 3 by an elastic telescopic structure. The elastic telescopic structure includes a first spring 3032 and a second spring 3042. The first spring 3032 is fixedly installed between the wiping assembly 3 and the wiping blade 303, and the second spring 3042 is fixedly installed between the wiping assembly 3 and the wiping plate 304.

[0041] like Figure 5 , Figure 6 and Figure 8 As shown, when the sliding handle 301 is moved in the direction of the wiping plate 304, the wiping component 3 will be moved in the direction of the wiping plate 304 due to the force. Therefore, the protrusion on the slider 302 will slide in the direction of the wiping plate 304 on the slide 201, and at the same time, the wiping component 3 will also slide on the slide 201.

[0042] At this time, the sliding handle 301 will rotate around the main shaft 3011, so the part of the sliding handle 301 near the protective lens 202 will rotate away from the wiping plate 304 and touch the wiping blade 303. When the part of the sliding handle 301 near the protective lens 202 touches the wiping blade 303, the wiping blade 303 will be rotated around the first rotating shaft 3031 under force. The first rotating shaft 3031 serves as the rotating shaft to divide the wiping blade 303 into a part away from the protective lens 202 and a part near the protective lens 202.

[0043] Therefore, when the part of the wiping blade 303 away from the protective lens 202 comes into contact with the sliding handle 301, it will rotate away from the wiping plate 304. At the same time, under the action of the first rotating shaft 3031, the part of the wiping blade 303 near the protective lens 202 will move towards the wiping plate 304. The first spring 3032 will also be stretched elastically. When the part of the wiping blade 303 near the protective lens 202 touches the first limiting post 306, the first limiting post 306 will restrict the movement of the wiping blade 303.

[0044] At this time, due to the opening of the wiping component 3 near the surface of the goggles 2, the wiping scraper 303 can rotate around the first rotating axis 3031 to directly contact the protective lens 202. As the wiping component 3 slides on the slide 201 toward the wiping plate 304, the wiping scraper 303 can clean and scrape the dust left on the surface of the protective lens 202 due to coal mining operations, which is very convenient and quick.

[0045] Preferably, the wiping scraper 303 is provided with a wedge-shaped scraper at one end near the protective lens 202, which can better scrape and clean the protective lens 202.

[0046] like Figures 5-7 As shown, when the sliding handle 301 is moved in the direction of the wiping blade 303, the wiping assembly 3 will be subjected to a force that moves in the direction of the wiping blade 303. Therefore, the protrusion on the slider 302 will slide in the direction of the wiping blade 303 on the slide 201, and at the same time, the wiping assembly 3 will also slide on the slide 201.

[0047] Simultaneously, due to the action of the main shaft 3011, the sliding handle 301 will rotate around the main shaft 3011. Therefore, the part of the sliding handle 301 near the protective lens 202 will rotate away from the wiping blade 303 under the action of the main shaft 3011 and touch the wiping plate 304. When the part of the sliding handle 301 near the protective lens 202 touches the wiping plate 304, the wiping plate 304 will rotate around the second rotating shaft 3041 under the force. The second rotating shaft 3041, as the rotating shaft, divides the wiping plate 304 into a part away from the protective lens 202 and a part near the protective lens 202. Therefore, when the part of the wiping plate 304 away from the protective lens 202 touches the sliding handle 301, it will rotate away from the wiping blade 303.

[0048] At the same time, under the action of the second rotating shaft 3041, a part of the wiping plate 304 near the protective lens 202 will move towards the wiping scraper 303, and the second spring 3042 will also be stretched elastically. When the part of the wiping plate 304 near the protective lens 202 touches the second limiting post 305, the second limiting post 305 will restrict the movement of the wiping plate 304.

[0049] At this time, due to the opening of the wiping component 3 near the goggles 2, the wiping plate 304 can rotate around the second rotating shaft 3041 to directly contact the protective lens 202. At the same time, the wiping plate 304 is equipped with a wiping cloth 3043. As the wiping component 3 slides on the slide 201 towards the wiping scraper 303, the wiping cloth 3043 installed on the wiping plate 304 can wipe away the dust during coal mine operations.

[0050] The wiping scraper 303 and the cleaning scraping plate 304 can remove dust left on the protective lens 202 during coal mining operations to the greatest extent. The dust removal efficiency is high, which improves the work efficiency of workers and ensures work safety.

[0051] like Figures 6-8 As shown, when the sliding handle 301 is moved towards the wiping plate 304, the sliding handle 301 rotates with the main shaft 3011, causing the part of the sliding handle 301 near the protective lens 202 to contact the wiping blade 303. Therefore, the wiping blade 303 can directly contact the protective lens 202 with the rotation of the first rotating shaft 3031. At the same time, the first spring 3032 elastically extends. If the sliding handle 301 is moved towards the wiping blade 303, the rotation of the sliding handle 301 around the main shaft 3011 causes the sliding handle 301 to approach the wiping blade 303. The portion of the protective lens 202 is moved away from the wiping blade 303, so the wiping blade 303 stops being stressed. The first spring 3032 will then move the wiping blade 303 away from the protective lens 202 due to its elastic contraction. At this time, the portion of the wiping blade 303 away from the protective lens 202 can be rotated towards the sliding handle 301 by the rotation of the first rotating shaft 3031. Therefore, the wiping blade 303 returns to its original position and no longer contacts the protective lens 202.

[0052] When the sliding handle 301 is moved towards the wiping blade 303, the sliding handle 301 rotates with the main shaft 3011, causing the portion of the sliding handle 301 near the protective lens 202 to contact the wiping plate 304. Therefore, the wiping plate 304 can directly contact the protective lens 202 as the second rotating shaft 3041 rotates. Simultaneously, the second spring 3042 elastically extends. If the sliding handle 301 is moved towards the wiping plate 304 at this time, the rotation of the sliding handle 301 around the main shaft 3011 causes it to approach the protective lens. The portion of 202 is moved away from the wiping plate 304, so the wiping plate 304 stops being stressed. The first spring 3032 will then move the wiping plate 304 away from the protective lens 202 due to its elastic contraction. At this time, the portion of the wiping plate 304 away from the protective lens 202 can be rotated towards the sliding handle 301 by the rotation of the second rotating shaft 3041. Therefore, the wiping plate 304 returns to its original position, and the wiping cloth 3043 on the wiping plate 304 does not contact the protective lens 202.

[0053] In this way, the wiping scraper 303 and the wiping plate 304 have a clear division of labor when they work, and will not interfere with each other, thus reducing the cleaning area and improving the wiping range and efficiency.

[0054] like Figure 4 As shown, magnets 203 are fixedly installed on both sides of the long side of the goggles 2. The magnets 203 can attract the wiping assembly 3. When the protective lens 202 does not need to be cleaned, the wiping assembly 3 can be moved to both sides of the goggles 2. The magnets 203 can directly attract the wiping assembly 3 to contact it, making it easy to store without obstructing vision. Preferably, in this embodiment, the wiping assembly 3 is preferably made of martensitic stainless steel, which has a lighter weight, higher hardness and wear resistance, and is also magnetic, making it suitable for the environment of coal mine operations.

[0055] like Figure 1 As shown, a safety helmet 4 is welded onto the helmet body 1. The safety helmet 4 can protect workers from the harm of falling stones. Preferably, in this embodiment, the safety helmet 4 is made of fiberglass. The edge of the safety helmet 4 is provided with a brim 401, which can increase the protection range and improve the structural strength of the safety helmet 4.

[0056] The helmet body 1 is equipped with a filter box 5, which has multiple filter holes 501. It is used to filter toxic and harmful gases, vapors and particulate matter in the air during coal mine operations, and can effectively protect the respiratory tract from damage and prevent pneumoconiosis.

[0057] Multiple vent valves 6 are installed on the helmet body 1, and filter plates 601 are installed on the multiple vent valves 6. The vent valves 6 can expel the air exhaled by the user into the helmet body 1, reducing the circulation of hot air inside the helmet body 1, which would cause the helmet body 1 to heat up and affect the user experience.

[0058] Meanwhile, there are no gaps between the safety helmet 4, filter box 5 and air valve 6 on the helmet body 1, which increases the protection range and effectively prevents coal dust face during coal mining operations.

[0059] In use, the head enters the helmet body 1 through the opening at the bottom of the helmet body 1, and the eyes are aligned with the protective lens 202. Then, work can begin. When dust accumulates on the protective lens 202, the sliding handle 301 is moved towards the wiping plate 304. At this time, the sliding handle 301 rotates around the main shaft 3011, causing the end of the sliding handle 301 near the protective lens 202 to touch the wiping blade 303. The wiping blade 303 is then subjected to force and rotates with the first rotating shaft 3031, and the first spring 3032 extends elastically. When the wiping blade 303 rotates to the first limit post 306, it stops rotating. At this moment, the end of the wiping blade 303 near the protective lens 202 touches the protective lens 202, and then the dust can be cleaned and scraped off. When the sliding handle 301 is moved towards the wiping blade 303, it rotates around the main shaft 3011, causing the end of the sliding handle 301 near the protective lens 202 to contact the wiping plate 304. Simultaneously, the wiping assembly 3 is not under force, so the first spring 3032 elastically contracts, allowing the wiping blade 303 to rotate around the first rotating shaft 3031 and reset. At the same time, the wiping plate 304 is subjected to force by the sliding handle 301 and rotates with the second rotating shaft 3041, causing the end of the wiping plate 304 near the protective lens 202 to contact the lens 202. A wiping cloth 3043 is mounted on the wiping plate 304, and when it contacts the protective lens 202, it removes dust. When the sliding handle 301 is moved towards the wiping plate 304 again, the wiping plate 304 is reset by the second spring 3042. This cycle repeats, improving wiping efficiency and expanding the dust cleaning area.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
