[0025] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0026] The terms "surface" and "surface" are based on the cool composite layer of the mask and the normal use state of the mask assembly structure. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0027] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] like Figures 1 to 3 As shown, the utility model discloses a cooling composite layer 1 for a mask, comprising a breathable bottom layer 10 and a cooling layer 2, wherein the breathable bottom layer 10 has a first surface 101 and a second surface 102; the cooling composite layer 1 is also provided with a guide slot 21 extending along its width direction, the guide slot 21 is penetrated along the thickness direction of the cooling composite layer 1, and is arranged on the side along its length direction.

[0029] In some embodiments, the cool layer 2 is fully laid on the first surface 101, and the cool layer 2 is also provided with a mouth and nose groove 20. The fully laid cool layer 2 increases the contact area with the face, dissipates heat in time and improves comfort. Among them, the full-page laying means that the mouth and nose groove 20 is not covered, ensuring that the wearer can breathe smoothly and communicate normally; it can also reduce the gravity of the cool composite layer, and combined with the setting of the mouth and nose groove structure, improve the supporting firmness of the bridge of the nose to the cool composite layer. The material of the cool layer is a hydrophilic polymer gel, which improves the fit firmness and stability with the bridge of the nose. Furthermore, the hydrophilic polymer gel includes ingredients such as water, glycerin, peppermint oil, borneol, eucalyptus oil leaves, etc.

[0030] In some embodiments, the cool layer 2 includes cool unit strips 22 arranged at intervals on the first surface 101, and the cool unit strips 22 are arranged crisscross on the first surface 101. The heat of the face is conducted through the crisscross cool unit strips 22, and the gaps between adjacent cool unit strips 22 and the face form a gap, which can improve air permeability and heat dissipation, while reducing the gravity of the cool composite layer, thereby improving the firmness and comfort of the cool composite layer 1 and the face. Due to the crisscross arrangement of the cool unit strips 22, it is conducive to breathing and ventilation. In order to further improve the comfort, the cool layer 2 is provided with a mouth and nose groove 20, and the cool unit strips 22 are arranged crisscross around the mouth and nose groove 20.

[0031] In some embodiments, the cooling layer 2 includes cooling unit strips 22 arranged at intervals on the first surface 101, and the cooling unit strips 22 are arranged on the first surface 101 in a direction extending from the center line of the breathable bottom layer to the circumferential side. Different wearers have different facial curves, and the divergent cooling unit strips 22 fit the face better, avoiding creases and arches in the flat cooling layer 2 after fitting, and the cooling layer 2 does not fit the face. In order to further improve the comfort, the cooling layer 2 is provided with a mouth and nose groove 20, and the cooling unit strips 22 are arranged from the mouth and nose groove 20 to the circumferential side.

[0032] The cool composite layer 1 for masks needs to be used in conjunction with the mask body 3, and the conventional mask body 3 is provided with a fixing belt 300. The cool composite layer 1 and the mask body 3 are not fixedly connected to maintain the relative stacking position between the two, and maintain the clamping state of the fixing belt 300 inserted in the guide slot 21 to prevent the fixing belt 300 from slipping off and reducing the wearing efficiency. Therefore, the guide slot 21 is surrounded by a hydrophilic polymer gel. It also achieves the firmness of the connection between the cool composite layer 1 and the mask body 3, and prevents the cool composite layer 1 from falling off from the face during long-term use or activities.

[0033] The breathable bottom layer 10 is an elastic nonwoven fabric, which is breathable and waterproof. It can ensure that the moisture of the polymer gel in the cooling layer will not easily penetrate out, and allow air to pass through to enhance the breathability. It also has a certain flexibility to ensure that it is both stable and comfortable when applied to the skin.

[0034] The surface of the cooling layer 2 facing away from the breathable bottom layer 10 is covered with a release film 4, which not only helps to maintain the bonding performance of the cooling layer 2, but also locks the moisture in the cooling layer 2 when not in use.

[0035] The cool composite layer 1 and the mask assembly include a mask body 3 and the above-mentioned cool composite layer 1 for the mask. The cool composite layer 1 and the mask body 3 are detachably connected. The mask body 3 is connected with a fixing belt 300 , and the fixing belt 300 is passed through the guide groove 21 .

[0036] The flexibility of different usage scenarios is improved, and a new cooling composite layer can be replaced when the cooling feeling of the cooling composite layer 1 is not good.

[0037] The length of the guide slot 21 is less than or equal to the distance between the fixed ends of the fixing belt 300. By controlling the length of the guide slot 21, the retracted state of the fixing belt 300 in the guide slot 21 along the length direction is adjusted to stabilize the position of the cooling composite layer 1 on the face.

[0038] The mask body 3 includes a waterproof layer 301, a filter layer 302 and a hygroscopic layer 303 stacked in sequence, wherein the breathable bottom layer 10 is adjacent to the hygroscopic layer 303, and the cool layer 2 faces the face. The waterproof layer 301 is made of spunbond nonwoven fabric, which is hydrophobic and is used to block the penetration of large particles, droplets, liquids, etc. from the outside, and prevent pollutants from directly contacting the filter layer. The filter layer 302 is a meltblown cloth, which is formed by polypropylene ultrafine fibers. The fiber diameter is very fine and can effectively filter tiny particles in the air, including bacteria, viruses, etc., to achieve the purpose of blocking pathogens from entering the respiratory tract. The hygroscopic layer 303 is also made of spunbond nonwoven fabric, and sometimes it can also be a soft material, which is responsible for absorbing exhaled water vapor and moisture, keeping the inside of the mask relatively dry, and improving wearing comfort.

[0039] In order to realize the anti-ultraviolet function of the mask, the surface of the waterproof layer 301 away from the filter layer 302 is provided with an anti-ultraviolet coating, or the waterproof layer 301 is an anti-ultraviolet outer layer.

[0040] Example 1

[0041] like Figures 1-2 As shown, the cool composite layer 1 for masks of Example 1 includes a breathable bottom layer 10 and a cool layer 2, the breathable bottom layer 10 has a first surface 101 and a second surface 102; the cool composite layer 1 is also provided with a guide slot 21 extending along its width direction, the guide slot 21 is penetrated along the thickness direction of the cool composite layer 1, and is divided along its length direction on the side. The cool layer 2 is fully laid on the first surface 101, and the cool layer 2 is also provided with a mouth and nose groove 20. The surface of the cool layer 2 facing away from the breathable bottom layer 10 is covered with a release film 4.

[0042] When the cool composite layer 1 is used with a mask, the assembly structure of the two includes a mask body 3 and the cool composite layer 1 for a mask, the cool composite layer 1 is detachably connected to the mask body 3, the mask body 3 is connected with a fixing belt 300, and the fixing belt 300 is inserted into the guide slot 21. Since the guide slot 21 is surrounded by a hydrophilic polymer gel, the release film 4 is first torn open, and then the harder release film 4 is bent, and the two sides of the bent release film 4 are inserted into the guide slot 21 to push it apart, which is conducive to the smooth insertion of the fixing belt 300.

[0043] The mask body 3 comprises a waterproof layer 301, a filter layer 302 and a moisture absorption layer 303 which are stacked in sequence, the breathable bottom layer 10 is adjacent to the moisture absorption layer 303, and the cooling layer 2 faces the face. The waterproof layer 301 is an anti-ultraviolet outer layer.

[0044] Example 2

[0045] like Figure 3 As shown, Embodiment 2 is based on Embodiment 1, and the difference is that the cooling layer 2 includes cooling unit strips 22 arranged at intervals on the first surface 101 , and the cooling unit strips 22 are arranged crisscross on the first surface 101 .

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
