Description

Technical Field

[0001] This utility model relates to the field of protective face shield technology, specifically a child protective face shield. Background Technology

[0002] Child protective face shields are personal protective equipment specifically designed for children's heads and faces. They are usually made of transparent, lightweight materials, cover the face, and fit snugly against the head. Their main function is to provide a physical barrier for children in specific situations, effectively blocking direct contact with airborne droplets, dust, pollen, and some pathogens, reducing the risk of respiratory infections and allergies. Because children's immune systems are not fully developed, their respiratory tracts are more vulnerable, and their self-protection awareness and ability are weaker, using protective face shields in public places, schools, or medical environments can provide them with an extra layer of passive protection and is an important tool to help maintain children's health.

[0003] A search revealed that patent number CN211932695U discloses a child protective face shield, comprising a mask body composed of multiple layers, an M-shaped sponge nose clip fixed to the upper inner side of the mask body, a malleable aluminum strip overlapping and fixed to the outer side of the mask body with the top of the nose clip, an eye protection device movably connected to the mask body via an upper strap, and a breathing valve fixed below the nose clip. The M-shaped sponge is densely covered with several small holes. This invention provides a double seal through the nose clip and malleable aluminum strip, with the inner nose bridge being an M-shaped sponge that fits snugly against the face, enhancing protection while ensuring comfort. Combined with the eye protection device, it reduces the difficulty for young children to independently wear separate masks and goggles, improving the stability of wearing them. This utility model has a good fit and protection, and is comprehensive, convenient and practical, and highly comfortable. However, the prior art is not convenient for children to adjust the tightness of the fit independently and quickly.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-3 As shown, a child protective face shield includes a face shield housing 1, a mask housing 2 is provided inside the face shield housing 1, a breathing valve 3 is provided outside the face shield housing 1 and the breathing valve 3 is connected to the mask housing 2, and air inlet pipes 4 are symmetrically arranged on both sides of the outside of the face shield housing 1, and a first filter element 5 is provided at one end of each of the two air inlet pipes 4. Two second filter elements 6 are symmetrically arranged on the outside of the first filter element 5, and a wearing mechanism 7 is provided on the outer side of the mask housing 1.

[0022] In this embodiment, the device is easy to wear and highly adaptable. The core component, the knob 78, can be operated simply by rotating, allowing children to wear it independently. The gear 77 precisely meshes with the groove 76 of the first strap 71, converting rotation into smooth extension and retraction of the strap to accommodate different head circumferences. The locking block 710 and the locking slot 711 automatically lock the length to prevent loosening. The second strap 8 provides additional fixation, enhancing stability during activities. Combined with the flexible fit of the first pad 9 and the second pad 10, it ensures both sealing protection and wearing comfort. The protective window glass 11 ensures a clear field of vision, comprehensively meeting the child's protection needs.

[0023] In one embodiment, such as Figure 1 and Figure 3As shown, the wearing mechanism 7 includes two first straps 71, both of which are fixedly installed on the outside of the mask housing 1. A protective shell 72 is fitted over the two first straps 71. A cover plate 73 is engaged on one side of the protective shell 72. A positioning block 74 is provided on one side of the cover plate 73. An installation component 75 is installed on one side of the cover plate 73 through the positioning block 74. A toothed groove 76 is provided on one side of each of the two first straps 71. A gear 77 is meshed inside each of the two toothed grooves 76. A knob 78 is fixedly connected to one end of the gear 77. A rotating screw 79 passes through one side of the knob 78. One end of the screw 79 passes through the gear 77 and is threadedly connected to the protective shell 72. Two locking blocks 710 are symmetrically arranged on the outside of the installation component 75. Multiple locking slots 711 are equidistantly arranged in a ring on the other side of the knob 78. The locking blocks 710 are compatible with each other. A second strap 8 is fixedly connected to the top of the mask housing 1. One end of the second strap 8 is fixedly connected to the protective shell 72. Two first straps 71 are symmetrically fixed to the outside of the mask housing 1. Together with the protective shell 72, they effectively protect the internal transmission components such as gears 77 and tooth grooves 76, preventing external impacts or dust from affecting the service life. The cover plate 73 is assembled by a snap-fit ​​method and achieves precise alignment with the positioning block 74. This facilitates quick disassembly and maintenance of internal parts and ensures structural sealing. The two locking blocks 710 on the mounting part 75 are precisely matched with the annular groove 711 of the knob 78. After adjustment, they can automatically engage and lock the length of the first strap 71 to prevent the mask from loosening or shifting when the child is active. By rotating the knob 78, the gear 77 can be driven to mesh with the tooth groove 76 of the first strap 71, realizing smooth extension and retraction of the strap. The operation is simple and can be completed independently by children, adapting to different head circumference requirements.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the inner wall of the mask housing 1 is provided with a first pad 9, the inner wall of the mask housing 2 is provided with a second pad 10, and a protective window glass 11 is provided on one side of the mask housing 1. A sealant is provided between the protective window glass 11 and the mask housing 1. The first pad 9 on the inner wall of the mask housing 1 and the second pad 10 on the inner wall of the mask housing 2 are made of flexible sealing material, which can closely fit the contours of a child's face. Under the tightening force of the straps of the wearing mechanism 7, it effectively blocks external droplets and particles from seeping into the facial gaps. At the same time, the flexible material can reduce the pressure on the child's skin and improve the comfort of wearing for a long time. The protective window glass 11 on one side of the mask housing 1 is made of high-transmittance material, ensuring a clear and unobstructed view for the child after wearing it. The sealant provided between it and the mask housing 1 can fill the seam gaps, preventing external pollutants from entering from the edge of the window and strengthening the overall sealing and protective performance of the mask.

[0025] The above embodiment discloses a child protective face shield. After the face shield is fitted to the face, the knob 78 of the wearing mechanism 7 is operated. When the knob 78 is turned, the gear 77 will be driven to rotate simultaneously. The gear 77 meshes with the tooth groove 76 on the surface of the first strap 71, thereby pulling the strap to shrink to fit the size of the child's head. After adjustment, the locking block 710 of the mounting piece 75 is engaged with the locking groove 711 of the knob 78 to lock the length of the strap. At the same time, the second strap 8 at the top assists in fixing, ensuring that the face shield is not easy to shift. When the straps are tightened, the first pad 9 on the inner wall of the mask shell 1 and the second pad 10 on the inner wall of the mask shell 2 fit tightly against the facial skin, preventing outside air from seeping in through the facial gaps; the sealant between the protective window glass 11 and the mask shell 1 simultaneously seals the gaps at the edge of the window, achieving an overall seal of the mask. Outside air enters through the air inlet pipe 4 and undergoes dual filtration through the second filter element 6 and the first filter element 5 in sequence, delivering clean air into the mask. The air exhaled by the child is discharged in one direction through the breathing valve 3 connected to the mask shell 2, avoiding the retention of exhaled air. At the same time, the protective window glass 11 ensures a clear field of vision while isolating external splashes and other risks, achieving dual protection for breathing and face.

[0026] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
