The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
 Such as figure 1 As shown, the disposable toe water-proof patch provided by this embodiment includes: a first layer 5 and a second layer 4;
 The lower surface of the first layer 5 is coated with a glue layer, which can be detachably bonded to the upper surface of the second layer 4;
 Two dividing lines 6 are symmetrically provided on the first layer 5;
 Two dividing lines 6 cut the first layer 5 into: left stick wing 3, right stick wing 1 and top stick 2;
 The shape and size of the top sticker 2 match the toe surface.
 In this embodiment, the first layer 5 and the second layer 4 can be easily separated, and then the first layer is pasted to the toe, and the top sticker wraps the upper surface of the toe; then the left and right wing attach The side surface of the toe is wrapped, thereby isolating the toe from the outside, so as to achieve the waterproof effect of the toe.
 The first layer 5 and the second layer 4 are rectangular paper sheets with the same shape and size.
 The upper surface of the first layer 5 is coated with a super-hydrophobic coating.
 The second layer 4 is release paper.
 The uncovered area 7 is provided on the first layer 5; the uncovered area 7 and the second layer 4 are not adhered; the uncovered area 7 is located at a corner of the first layer 5.
 In this embodiment, the release paper and the adhesive layer can be easily separated. The uncovered area 7 does not adhere to the second layer 4, and the function is that the user can easily separate the first layer 5 and the second layer 4.
 The two dividing lines 6 respectively start from the middle of the first layer 5 and end at two vertices on one side of the first layer 5.
 The two dividing lines 6 do not intersect, and the starting point is not shared. The two dividing lines 6 are located on the same parabola. The distance between the starting points of the two dividing lines 6 is n, and the distance between the ending points of the two dividing lines 6 is m, so that: m≤6n. The distance between the vertex of the parabola where the two dividing lines 6 are located and the long side where the end points of the two dividing lines 6 are located is l, and the length of the short side of the first layer 5 is p, so that: p>l≥2/3p.
 In this embodiment, figure 1 In the middle, the side where the left sticking wing 3 is located is the left side, and the side where the right sticking wing 1 is located is the right side. The corner where the area 7 is uncovered is the upper left corner of the first layer 5. The uncovered area 7 is set away from the end points of the two dividing lines 6.
 Such as figure 2 As shown, this embodiment only needs to remove the second layer 4 when in use, and after unfolding the first layer 5, stick the sticky side of the top sticker 2 on the toe, and then stick the left wing 3 and the right wing 1 Stick the sticky side to both sides of the toe. After the first layer 5 is separated from the second layer 4 and pasted on the toe of the shoe, in this embodiment, m=6n; l=2/3p. The above-mentioned dimensions can ensure that the toe of the shoe is completely covered; and the left and right wing 3 can also fix the edges of the top sticker 2, making the top sticker 2 stronger.
 This embodiment is simple in structure, convenient and easy to use, low in manufacturing cost, and can be mass-produced. It can solve the problem that dirty water on the ground is rolled onto the toe of the shoe and penetrates into the shoe when people walk, and avoids that the dirty water infiltrates the toe and the toe is wet. This leads to the trouble of having to change shoes to go out, reducing the burden of people cleaning up the toe stains; at the same time, it also prevents dirty water from leaking into the shoes and affecting people's health. In this embodiment, individual decoration can also be performed, and various colors and patterns can be added to satisfy the aesthetics of different people.
 It should be understood that the specific order or hierarchy of steps in the disclosed process is an example of an exemplary method. Based on design preferences, it should be understood that the specific order or level of steps in the process can be rearranged without departing from the scope of protection of the present disclosure. The accompanying method claims present elements of the various steps in an exemplary order and are not intended to be limited to the specific order or hierarchy described.
 In the above detailed description, various features are combined together in a single embodiment to simplify the present disclosure. This method of disclosure should not be interpreted as reflecting the intent that the implementation of the claimed subject matter requires more features than those clearly stated in each claim. On the contrary, as reflected in the appended claims, the present invention is in a state with fewer features than the single disclosed embodiment. Therefore, the appended claims are hereby clearly incorporated into the detailed description, with each claim standing alone as a separate preferred embodiment of the present invention.
