[0002] A hard hat with a face mask is a personal protective equipment used to protect the head and face. It usually consists of a cap shell, a face mask and a headband, which can provide multiple protections. Face mask hard hats are commonly used in mines, construction sites, industrial manufacturing and laboratories.
[0003] Among them, when used on a construction site, a helmet with a mask is used during operations such as crushing and welding on the site (such as steel bar cutting and shotcrete spraying) to prevent the splashing of gravel, dust and metal debris generated during the operation from damaging the worker's face. For example, the Chinese patent with announcement number CN210276065U discloses a helmet with a transparent mask. However, when the mask is in use, due to the high dust content in the use scene, the splashing metal debris or dust will adhere to the outer surface of the mask, which reduces the visibility of the mask and limits the field of vision. Therefore, when there is a lot of dust accumulation, the worker needs to put down the tools in his hands, take off the gloves, and then wipe the mask, or temporarily use the corner cloth of clothes to wipe it. If the wiping is not good enough, the helmet needs to be taken off and then wiped. In addition, taking off the helmet on a construction site is also very dangerous. Therefore, a helmet with a mask is designed to solve the above-mentioned problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example
[0020] See also Figure 1-3 The present embodiment provides a safety helmet with a mask, including a safety helmet 1 and a transparent mask 3, a restoration component, a cleaning component, and an adjustment component. A positioning component 2 is fixedly installed on the rear of the safety helmet 1. The positioning component 2 is composed of a micro battery, a positioning sensor and an indicator light. Please refer to the Chinese patent announcement number: CN212368426U. A construction safety helmet with a positioning and temperature monitoring device is a commonly used technical means in this field and will not be described in detail here.
[0021] like Figure 1 As shown, a mounting groove is provided on the outer side of the transparent mask 3 near the ear, and the side wall of the mounting block 7 is slidably connected in the mounting groove. The two mounting blocks 7 are fixedly connected to the mounting ring 4 along the outer side wall of the transparent mask 3. The mounting ring 4 is as shown in FIG. Figure 3 As shown in the figure, the mounting ring 4 is in a ring shape, and a plurality of first elastic sheets 5 are fixedly connected to the side close to the transparent mask 3, and the first elastic sheet 5 is fixedly connected to the side away from the mounting ring 4. The first elastic sheet 5 provides elastic force to make the cleaning scraper 6 close to the outer wall of the transparent mask 3. The first elastic sheet, the mounting ring 4, the cleaning scraper 6 and the mounting block 7 constitute a cleaning assembly, and the cleaning assembly moves up and down to complete the cleaning of the transparent mask 3.
[0022] When supporting the foundation pit, cutting steel bars, and spraying concrete at the construction site, the working environment is dusty, especially when spraying concrete, concrete will splash on the mask, thereby adhering dust impurities. When cleaning the mask, the installation block 7 (or the installation ring 4) can be pushed down by hand, so that the installation block 7 and the installation ring 4 drive the cleaning scraper 6 to descend synchronously, and the cleaning scraper 6 cleans the dust on the transparent mask 3 when it moves. When cleaning, since the installation block 7 is relatively small in structure, it is not convenient for workers to push the installation block 7 while wearing gloves, and the installation ring 4 can be directly pushed to perform the cleaning work. However, since the installation ring 4 is located right in front of the transparent mask 3 and is relatively close to the transparent mask 3, when the hand pushes the installation ring 4, the hand is easy to contact with the transparent mask, resulting in the dirt of the hand sticking to the transparent mask or the fingerprint of the hand (or hand trace) is printed on the transparent mask 3, affecting the line of sight and observation.
[0023] Therefore, a connecting rod 10 is also rotated at a position near the ear of the transparent mask 3, and a pressing plate 8 is fixedly connected to the side of the rotating rod 10. The initial position of the pressing plate 8 is as shown in FIG. Figure 1 As shown, it is placed at an angle, and the side of the pressing plate 8 away from the rotating rod 10 is a bent portion. Figure 3 For example, the rotating rod 10 is composed of a circular block and a cylinder, wherein the circular block is fixedly connected to a torsion spring 9 on one side close to the transparent mask 3, one end of the torsion spring 9 is fixedly connected to the cylinder of the rotating rod 10, and the other end of the torsion spring 9 is fixedly connected to the side wall of the transparent mask 3. The rotating rod 10, the torsion spring 9 and the pressure plate 8 constitute an adjustment assembly. When in use, the rotating rod 10 is twisted to make the rotating rod 10 drive the pressure plate 8 to rotate and the torsion spring 9 to rotate. When the rotating rod 10 is loosened, the torsion spring 9 plays a role in restoring the rotating rod 10 and restoring the pressure plate 8 connected on one side.
[0024] The specific method of using the adjustment assembly is as follows: the pressing plate 8 is pressed downward by hand, and the pressing plate 8 and the rotating rod 10 rotate with the axis of the rotating rod 10 as the axis, forcing the mounting block 7 to be squeezed and then drive the mounting ring 4 and the cleaning scraper 6 to descend. During the descent, the cleaning scraper 6 scrapes off the dust and metal debris adhering to the transparent mask 3. When the pressing plate 8 rotates and presses the mounting block 7 downward, the mounting block 7 drives the cleaning scraper 6 to move. Due to the friction between the cleaning scraper 6 and the transparent mask 3, the cleaning scraper 6 is blocked and the downward force is applied to the transparent mask 3, thereby scraping off the dust and metal debris on the transparent mask 3 more forcefully, so that the cleaning scraper 6 can scrape cleanly.
[0025] After the cleaning scraper 6 is lowered to clean the transparent mask 3, the restoring force provided by the torsion spring 9 to the rotating rod 10 enables the rotating rod 10 to drive the pressing plate 8 to recover so as to be used next time.
[0026] After the cleaning scraper 6 descends to clean the transparent mask 3, the cleaning scraper 6 is at the lower end of the transparent mask 3 and does not affect the field of view of the transparent mask 3. However, in order to facilitate the next cleaning of the transparent mask 3, the No. 2 elastic sheet 11 is fixedly connected in the mounting groove, and the upper end of the No. 2 elastic sheet 11 is fixedly connected to the mounting block 7; during the descent process, the cleaning scraper 6 squeezes the No. 2 elastic sheet 11 on one side of the mounting block 7 to shrink the No. 2 elastic sheet 11. When the pressure plate 8 no longer provides pressure to the mounting block 7, the No. 2 elastic sheet 11 is restored to drive the mounting block 7 and the cleaning scraper 6 to rise, thereby restoring the cleaning scraper 6 for reuse.
[0027] In addition, the second elastic sheet 11 also supports the mounting block 7 and the mounting ring 4. After long-term use, the friction between the mounting block 7 and the mounting groove will cause the friction between the two to become smaller and smaller, and even a gap will appear between the two. This will cause the mounting block 7 and the mounting ring 4 to fall downward under the action of their own gravity, and it is impossible to ensure that the cleaning component is located at the top of the mounting groove, thereby affecting the field of vision. By providing the second elastic sheet 11, the cleaning component can be ensured to be located at the top of the mounting groove under the elastic force of the second elastic sheet 11.
[0028] The mounting groove is directly exposed to the outside, and dust will enter the mounting groove during use, causing blockage in the mounting groove, affecting the use of the second elastic sheet 11. Therefore, a protective soft belt is fixedly connected at the lower end of the mounting block 7 and away from the side of the mounting groove. Figure 1 As shown, the protective soft belt is located in the installation groove, which is used to protect the installation groove and prevent dust from directly entering the installation groove and affecting the use of the second elastic piece 11.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
