Specific implementation

[0028] In order to make the personnel in the technical field better understand the technical scheme in the utility model, the technical scheme in the embodiment of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor should belong to the protection scope of the utility model.

[0029] As Figures 1 to 4 The utility model discloses an embodiment of a medical mask, including face screen 1, the cross section of face screen 1 is arc, and face screen 1 is installed with tie 11, and the medical mask still includes cushion block 12 and wiping assembly. Wherein cushion block 12 is fixedly connected on the end face of face screen 1 close to the wearer, and the wiping assembly includes a pair of sliding blocks 2, and the pair of sliding blocks 2 are symmetrically slidably connected on the two side walls of face screen 1, and the pair of sliding blocks 2 are installed with the sponge block 221 and face screen 1 is attached.

[0030] ​​Specifically, the strap 11 is an elastic strap, which can hold the head of the wearer; the cushion 12 is wrapped with soft cushion, which is placed on the forehead of the wearer, and increases the comfort degree of the wearer during use. Moreover, the thickness of the cushion 12 is greater than the height of the normal nose bridge of the wearer, so that the face shield 1 and the face of the wearer have a certain distance, which is convenient for the wearer to breathe.

[0031] When the face shield 1 is fogged, the sponge block 221 on the pair of sliders 2 can slide on the face shield 1 by sliding the pair of sliders 2, so as to wipe off the fog on the face shield 1.

[0032] It is worth noting that, in order to prevent the sliders 2 from contacting the face of the wearer and affecting the sliding on the face shield 1, the thickness of the sliders 2 is less than the thickness of the cushion 12.

[0033] In addition, since the head circumference of men and women is quite different, in order to prevent the strap 11 from being too tight, the strap 11 is provided with a through hole, and the face shield 1 is provided with a snap buckle 14 matched with the through hole of the strap 11. Specifically, the snap buckle 14 is divided into a male buckle and a female buckle, the female buckle is installed on the face shield 1, and the male buckle penetrates through the through hole of the strap 11 and is pressed on the female buckle on the face shield 1. Through the cooperation of the male buckle and the female buckle, different lengths of the strap 11 can be replaced according to the needs.

[0034] As shown in Figures 3 to 7 The slider 2 is integrally formed with a clamping plate 21, and the lower end surface of the cushion 12 is provided with a first clamping groove 121 matched with the clamping plate 21. When the clamping plate 21 is inserted into the sponge block 221, it can fix the slider 2 and prevent the slider 2 from sliding on the face shield 1. Further, the clamping plate 21 is wrapped with a rubber pad 211, and the elastic force of the rubber pad 211 can make the clamping plate 21 firmly clamped in the first clamping groove 121, preventing the clamping plate 21 from falling off from the first clamping groove 121 when the wearer moves violently.

[0035] When the weather is cold and the face shield 1 is worn for a long time outdoors, the fog on the face shield 1 is serious and will condense into water droplets. The sponge block 221 loses its original wiping effect after absorbing too much water. In order to replace the sponge block 221, the slider 2 is integrally formed with a fixing block 22, the fixing block 22 is provided with a second clamping groove 2201, and the two side walls of the sponge block 221 are respectively bonded with clamping blocks 2211 matched with the second clamping groove 2201.

[0036] Specifically, the clamping blocks 2211 can slide in the second clamping grooves 2201, and the sponge block 221 is clamped on the pair of fixing blocks 22 through the clamping blocks 2211. The wearer can replace the sponge block 221 after lunch to ensure subsequent work.

[0037] Further, in order to prevent the clamping block 2211 from sliding out of the second clamping groove 2201 when the slider 2 slides downward, an insertion groove 2202 is formed on the fixed block 22, the insertion groove 2202 penetrates the two side walls of the second clamping groove 2201, and a locking column 26 is inserted into the insertion groove 2202.

[0038] The locking column 26 can press the clamping block 2211 in the second clamping groove 2201, so that the clamping block 2211 cannot slide upward from the second clamping groove 2201 under the force of the sponge block 221. When replacing the sponge block 221, pulling out the locking column 26 in the insertion groove 2202 can replace the sponge block 221.

[0039] In addition, the first water scraping strip 222 is attached to the fixed block 22 and is located at the lower end of the sponge block 221. When the slider 2 slides downward, the first water scraping strip 222 can scrape off a large part of the water droplets on the face screen 1, reducing the water absorption of the sponge block 221 and prolonging the service life of the sponge block 221.

[0040] It is worth noting that the water droplets scraped off by the first water scraping strip 222 will directly fall off, and if the wearer is doing detection work, these falling water droplets will fall into the sample, causing the detection result to be invalid. A limiting strip 13 is attached to the end face of the face screen 1 close to the wearer, and a water-absorbing cloth 131 is wrapped around the limiting strip 13.

[0041] Specifically, the water-absorbing cloth 131 can absorb the water droplets scraped off by the first water scraping strip 222 to prevent them from falling. At the same time, the water-absorbing cloth 131 can also absorb the water droplets that naturally fall off the face screen 1. In addition, the limiting strip 13 can also limit the slider 2 to prevent it from falling off the face screen 1.

[0042] Further, the slider 2 is integrally formed with a pressing plate 25, and the pressing plate 25 can be pinched and moved up and down, which is convenient to operate.

[0043] As shown in Figure 1 , Figure 3 and Figure 4 , a pair of sliders 2 are attached with a connecting plate 23, which can connect the pair of sliders 2, and when sliding the pair of sliders 2, only one side of the slider 2 needs to be pressed to make the two sliders 2 slide on the face screen 1 at the same time, which is convenient for the wearer to use.

[0044] Although the end face of the face screen 1 far from the wearer is not easy to fog, if liquid splashes on the face screen 1 during detection, it will also affect the line of sight. Further, a second water scraping strip 24 is attached to the lower end face of the connecting plate 23, and the second water scraping strip 24 is attached to the end face of the face screen 1 far from the wearer. When the slider 2 moves downward, the second water scraping strip 24 can clean the end face of the face screen 1 far from the wearer.

[0045] In use, the pressing plate 25 is pinched and pulled down, the pair of sliding blocks 2 slide on the face screen 1, and the sponge block 221 on the sliding block 2 can wipe the water mist and water droplets on the end face of the face screen 1 close to the wearer, so as to ensure the wearer's vision is not affected.

[0046] Through the above operation, the mist on the medical mask can be easily wiped off, the wearer is provided with a clear field of vision, thus effectively avoiding the safety hazards such as misdiagnosis and misoperation caused by blurred vision, and the safety and accuracy in the medical protection process are improved.
