TECHNICAL FIELD

[0001] The present application relates to the technical field of masks, in particular to a willow leaf type mask. BACKGROUND

[0002] At present, masks are common health protection products. The masks on the market are mainly flat type, folding type and willow leaf type. The willow leaf type mask is like a willow leaf, and has the advantages of comfort, aesthetics and cost performance.

[0003] A willow leaf type mask for preventing leakage and wearing displacement is disclosed in Chinese Patent No. CN216147307U, which comprises a middle connecting piece, ear band ropes arranged on both sides of the middle connecting piece, an elastic upper fin edge piece fixedly connected to the inner side of the top of the middle connecting piece, and an elastic lower fin edge piece fixedly connected to the inner side of the bottom of the middle connecting piece. When the mask is sold or used, the elastic upper fin edge piece and the elastic lower fin edge piece are folded and attached to the inner side of the middle connecting piece to save space.

[0004] In the related technology described above, when in use, the elastic upper fin edge piece can be turned up, and the elastic lower fin edge piece can be turned down to form a large enough area to cover the part below the eyes of the face. However, when the elastic upper fin edge piece is turned up, an upward opening groove is formed between the bottom of the elastic upper fin edge piece and the upper end of the middle connecting piece, and the groove is located in the outer side direction of the mask. When in use, especially when there are a lot of dust and debris outside, dust and debris are likely to accumulate in the groove when they touch the elastic upper fin edge piece, which results in a lot of dust and debris remaining on the mask, affecting the cleanliness when the mask is temporarily stored after being taken off. SUMMARY

[0005] In order to reduce the accumulation of dust, debris and other impurities on the mask and improve the cleanliness of the mask when it is stored after being taken off, the present application provides a willow leaf type mask.

[0006] The willow leaf type mask provided by the present application adopts the following technical solution:

[0007] A willow leaf type mask comprises a middle piece, an upper fin edge piece and a lower fin edge piece. The lower side of the upper fin edge piece is connected to the position close to the upper side of the middle piece. The upper side of the lower fin edge piece is connected to the position close to the lower side of the middle piece. An upward opening groove is formed between the lower side of the upper fin edge piece and the upper side of the middle piece. An outer shielding piece is arranged on the outer side of the upper fin edge piece and close to the middle piece. The outer shielding piece is foldably arranged on the upper fin edge piece. When the mask is worn and used, the inner side of the outer shielding piece is attached to the outer edge of the upper end of the middle piece, and the outer shielding piece covers the opening of the groove.

[0008] By adopting the technical scheme, when the mask needs to be used, the upper fin edge piece attached to the middle piece is folded upward and the lower fin edge piece attached to the middle piece is folded downward, so that the whole mask is opened; after the upper fin edge piece is opened, the outer shielding piece can cover the upper end slot of the groove, so that when there are more dust and debris outside, the outer shielding piece can play a shielding role to limit the dust and debris from falling into the groove, and most of the dust and debris will slide off when falling onto the outer shielding piece, thereby reducing the residue of dust, debris and other sundries on the mask and improving the cleanliness of the mask when it is stored after being taken off.

[0009] Preferably, a clamping strip is arranged on the outer shielding piece along the length direction of the outer shielding piece, the clamping strip is located at a position away from the upper fin edge piece, and the clamping strip is located on the outer side of the upper edge of the middle piece.

[0010] By adopting the technical scheme, when the outer shielding piece covers the slot of the groove, the clamping strip can abut against the outer side of the upper fin edge piece to play a limiting role, so that the end of the outer side piece away from the upper fin edge piece is clamped into the groove, and the outer shielding piece can better cover the slot of the groove.

[0011] Preferably, the clamping strip comprises a plastic part, and the plastic part can be plastically deformed.

[0012] By adopting the technical scheme, the plastic part has plastic deformation capability and can play a role in shaping the position where the upper fin edge piece and the middle piece are close to each other, which is generally located at the tip of the nose. By adjusting the plastic part, the extrusion of the mask on the bridge of the nose can be reduced, and the comfort during wearing can be improved.

[0013] Preferably, the clamping strip further comprises a flexible part, the flexible part is wrapped on the outer side of the plastic part, and the flexible part is connected with the outer shielding piece.

[0014] By adopting the technical scheme, the flexible part has good deformation capability, so that the clamping strip can better fit the upper end outer side of the middle piece and the gap between the clamping strip and the upper end outer side of the middle piece.

[0015] Preferably, a flexible anti-fog part is arranged at the inner side of the upper fin edge piece and close to the middle, the anti-fog part is attached to the two sides of the bridge of the nose, and an air isolation piece is arranged at the upper end of the anti-fog part.

[0016] By adopting the technical scheme, since the mask has an arc-shaped transition part between the nose bridge and the cheek when worn, there is a gap between the two sides of the nose bridge and the inner side of the upper fin edge sheet; and when the person wearing glasses uses the mask in cold weather, hot air is easily emitted from the gap during exhalation, forming water mist on the glasses; the design of the protection part can better fill the gap, and the air isolation sheet can reduce the penetration of hot air through the anti-fog part, thereby achieving the effect of anti-fog, and reducing the inflow of external air to improve the protection effect.

[0017] Preferably, the anti-fog part comprises two flexible bumps, the two flexible bumps are located on both sides of the middle of the upper fin edge sheet, the upper end of the flexible bump is flush with the upper fin edge sheet and is a mounting plane, and the air isolation sheet is arranged on the mounting plane.

[0018] By adopting the technical scheme, the flexible bump can better fit on both sides of the nose bridge, thereby reducing the gap between the inner side of the upper end of the mask and the face, and the mounting plane can facilitate the fixation of the air isolation sheet on the anti-fog part.

[0019] Preferably, one side of the flexible bump away from the upper fin edge sheet is arc-shaped.

[0020] By adopting the technical scheme, since the transition between the nose bridge and the cheek is basically arc-shaped, the arc-shaped flexible bump can better block the transition gap between the nose bridge and the cheek.

[0021] Preferably, a shaping part is arranged on the outer side of the lower edge of the lower fin edge sheet, and the shaping part is arranged in a direction close to the middle sheet.

[0022] By adopting the technical scheme, the shaping part arranged in a direction close to the middle sheet can shape the lower fin edge sheet to better fit the bottom surface of the lower jaw of the head through the shaping part, thereby achieving better protection effect.

[0023] Preferably, the outer side of the shaping part is wrapped with a flexible sleeve, and the outer side of the flexible sleeve is fixed with the outer side of the lower edge of the lower fin edge sheet.

[0024] By adopting the technical scheme, the flexible sleeve wraps the shaping part, thereby improving the isolation protection effect between the shaping part and the face, reducing the hard extrusion of the positioning part on the face, and improving the safety of using the shaping part at the lower end of the mask.

[0025] Preferably, the connection position of the outer shielding sheet and the upper fin edge sheet is higher than the uppermost end position of the middle sheet.

[0026] By adopting the above technical scheme, when the upper fin edge sheet of the mask is folded upward and the outer shielding sheet shields the groove opening, the outer shielding sheet can be inclined downward away from the face, so that most of the dust debris and the like can freely slide off when falling on the outer shielding sheet.

[0027] To sum up, the present application includes at least one of the following beneficial technical effects:

[0028] (1) By setting the outer shielding sheet, when the upper fin edge sheet is folded and opened, the outer shielding sheet can shield the groove opening, thereby reducing the residue of dust, debris and the like on the mask, and improving the cleanliness of the mask when it is stored after being taken off;

[0029] (2) By setting the cooperation between the anti-fog part and the air isolation sheet, the gap between the two sides of the nose bridge and the cheeks can be better blocked, the influence of the fog on the glasses is reduced, and the anti-fog effect is achieved;

[0030] (3) By setting the shaping piece, the lower side of the lower fin edge sheet can be bent and shaped, so that the lower fin edge sheet better fits the bottom surface of the lower jaw, and the protection effect of the mask is improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be described in detail with reference to the accompanying drawings. Figures 1-4 The present application will be further described in detail.

[0037] The present embodiment discloses a willow leaf type mask. Referring to Figure 1 , the willow leaf type mask includes a middle sheet 1, an upper fin edge sheet 2, a lower fin edge sheet 3 and an outer shielding sheet 4. In the present embodiment, the orientation when the mask is normally worn is described, the side of the mask facing the face is the inner side, and the side of the mask away from the face is the outer side.

[0038] Referring to Figure 1 andFigure 2 The two sides of the middle piece 1 are fixed with ear bands 11. The lower edge of the upper fin edge piece 2 is hot melt connected to the middle piece 1 near the upper side, and there is a gap between the lower side of the upper fin edge piece 2 and the upper end edge of the middle piece 1; the upper side of the lower fin edge piece 3 is connected to the middle piece 1 near the lower side, and there is a gap between the upper side of the lower fin edge piece 3 and the lower end edge of the middle piece 1, and the upper fin edge piece 2 and the lower fin edge piece 3 are both folded and connected to the inner side of the middle piece 1. A groove 5 with its notch facing upwards is formed between the lower side of the upper fin edge piece 2 and the upper end edge of the middle piece 1, and the outer cover piece 4 is in the shape of a strip. The outer cover piece 4 is made of non-woven fabric, and the upper side of the outer cover piece 4 is connected to the upper fin edge piece 2 near the middle piece 1. The outer cover piece 4 can be folded and fixed to the upper fin edge piece 2. When the mask is worn and used, the lower end of the outer cover piece 4 is inclined away from the face, the inner side of the outer cover piece 4 is attached to the upper end outer edge of the middle piece 1, and the outer cover piece 4 covers the notch of the groove 5. Therefore, the outer cover piece 4 can play a shielding role, reducing the falling of dust and debris into the groove 5, and most of the dust and debris falling on the upper surface of the outer cover piece 4 will slide off.

[0039] Referring to Figure 2 and Figure 3 A clamping strip 6 is fixed on the outer cover piece 4 along the length direction of the outer cover piece 4, and the clamping strip 6 is located away from the upper fin edge piece 2. The clamping strip 6 includes a plastic part 61 and a flexible part 62, the flexible part 62 is wrapped on the outer side of the plastic part 61, the plastic part 61 can be plastically deformed, and the flexible part 62 is connected to the outer cover piece 4. The flexible part 62 is selected to be a flexible cloth cover, and the plastic part 61 is selected to be a common nose bridge strip made of metal wire or resin material. The clamping strip 6 is located in the outer side direction of the upper edge of the middle piece 1 and abuts to the outer side of the upper edge of the middle piece 1. The clamping strip 6 can limit the side of the outer cover piece 4 away from the upper fin edge piece 2, reduce the falling of the lower end of the outer cover piece 4 away from the upper fin edge piece 2 into the groove 5, and ensure that the outer cover piece 4 can better cover the notch of the groove 5. At the same time, when the mask is worn, the position of the nose tip is close to the connection position of the middle piece 1 and the upper fin edge piece 2, and the clamping strip 6 has the ability of plastic shaping, which can shape the part of the mask close to the middle piece 1 and the upper fin edge piece 2, reduce the extrusion of the mask on the nose tip, and improve the comfort during wearing.

[0040] Referring to Figure 1 and Figure 4When the mask is worn, a large arc-shaped transition surface is formed between the two sides of the nose bridge and the cheeks, so that the upper edge of the upper fin edge sheet 2 cannot better fit the transition surface between the two sides of the nose bridge and the cheeks, and there is a gap between the position of the upper fin edge sheet 2 on the two sides of the nose bridge and the face. When exhaling in cold weather, hot air diffuses upward from the gap and easily produces mist that affects the glasses. Therefore, a flexible anti-fog part 7 is fixed to the inner side of the upper fin edge sheet 2 and near the middle, the anti-fog part 7 is fitted to the two sides of the nose bridge, and the upper end of the anti-fog part 7 is provided with an air separation sheet 8. The anti-fog part 7 is selected to be a sponge material, and the air separation sheet 8 is selected to be a film. The anti-fog part 7 can block the gap between the upper fin edge sheet 2 and the two sides of the nose bridge, and the air separation sheet 8 can limit the hot air from passing through the anti-fog part 7, thereby reducing the effect of the mist on the glasses. At the same time, the anti-fog part 7 and the air separation sheet 8 can also reduce the entry of external pollutants into the inside of the mask, achieving better protection effect.

[0041] Specifically, the anti-fog part 7 includes two flexible lugs, which are located on both sides of the middle of the upper fin edge sheet 2. The side of the flexible lug away from the upper fin edge sheet 2 is arc-shaped to better fit the two sides of the nose bridge. The upper end of the flexible lug is flush with the upper fin edge sheet 2. The position where the flexible lug is flush with the upper fin edge sheet 2 is the mounting plane, and the air separation sheet 8 is bonded to the mounting plane, facilitating the installation of the air separation sheet 8.

[0042] In addition, a shaping part 9 is fixed to the outer side of the lower edge of the lower fin edge sheet 3, and the shaping part 9 extends in the direction close to the middle piece 1. In this embodiment, the shaping part 9 is spaced apart by five pieces, and each shaping part 9 is spaced apart along the horizontal direction of the mask. The outer side of the shaping part 9 is wrapped with a flexible sleeve 10, which is a cloth sleeve. The shaping part 9 is also selected to be a common nose bridge strip metal wire or a resin material made of a rubber strip, which can be bent and deformed under external force. The outer side of the flexible sleeve 10 is bonded and fixed to the outer side of the lower edge of the lower fin edge sheet 3.

[0043] The implementation principle of the willow leaf type mask of the embodiment of the present application is as follows: when the mask is used, the upper fin edge sheet 2 is folded upward, and the lower fin edge sheet 3 is folded downward, so that the entire mask is opened for wearing. After the upper fin edge sheet 2 is opened, the lower side of the outer cover sheet 4 is turned upward to cover the upper end slot of the groove 5. Therefore, when there is a lot of dust and debris outside, the outer cover sheet 4 can block the slot of the groove 5, limiting the dust and debris from falling into the groove 5. When the dust and debris fall on the outer cover sheet 4, most of them will slide off, thereby reducing the residue of dust, debris and other impurities on the mask and improving the cleanliness of the mask when it is stored after being taken off.

[0044] Furthermore, the anti-fog part can block the gap between the upper end of the upper fin edge sheet and the two sides of the nose bridge, reduce the mist from rising and producing mist, and thus reduce the influence of the mist.

[0045] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
