Abstract
Description
Technical Field
[0001] This utility model relates to mirrors, and more specifically, to a bathroom mirror. Background Technology
[0002] Thin-film mirrors are increasingly used in bathrooms due to their lightweight, durability, good reflectivity, and resistance to condensation. Existing thin-film mirrors are made by stretching a PET base film with a metal electroplated layer on the back onto a metal frame. Although the PET base film of thin-film mirrors has an additional anti-oxidation layer on top of the metal electroplating layer, oxidation black spots still appear on the PET base film after prolonged exposure to the high humidity of a bathroom environment, thus affecting the mirror's usability. Utility Model Content
[0003] This invention proposes a bathroom mirror, the purpose of which is to solve the problem of existing thin-film mirrors being oxidized when directly exposed to the high humidity of the bathroom environment.
[0004] Because of the above-mentioned technical solution, this utility model adopts the following technical solution:
[0005] A bathroom mirror includes: a mirror frame, the back surface and four sides of which are coated with an adhesive layer; a PET film, which is stretched in all directions by mechanical equipment with a tensile tension of 2-10 Newtons, covering the front surface of the mirror frame and adhering to the adhesive layer on the four sides of the mirror frame, the back of the PET film being plated with a metal electroplated layer; silver cardboard, which is attached to the adhesive layer on the back surface of the mirror frame and joins the edge of the PET film; a waterproof membrane, which is attached to the back surface of the silver cardboard; and a sealant layer, which is coated on the edge of the silver cardboard and the edge of the PET film, sealing the junction of the silver cardboard and the PET film.
[0006] Preferably, the frame includes an I-shaped frame body and two sets of opposing mirror support rods protruding from the front surface of the frame body; the back of the frame body is flat to attach the silver cardboard, and the mirror support rods support the PET film.
[0007] Preferably, the surface corners of the mirror strut are blunted.
[0008] Preferably, the I-shaped frame body has at least one sealing strip to form at least one sealed space.
[0009] Preferably, a magnetic structure is provided on the rear surface of the frame, and the magnetic structure is fixed to the edge of the sealed space.
[0010] Preferably, a rotating fastening structure is provided on the rear surface of the frame, and the rotating fastening structure is fixed to the edge of the sealed space.
[0011] Preferably, an adhesive structure is provided on the rear surface of the frame.
[0012] Preferably, the sealing layer is a sealant layer or a sealing aluminum foil tape layer.
[0013] By adopting the above technical solution, this utility model improves the structure of the mirror, so that the back of the PET film is sealed between the mirror frame, the silver cardboard and the waterproof film, preventing contact with water vapor, and the overall weight is still very light, with no safety hazards.

[0016] Figure 3 This is a schematic diagram of the back of an embodiment of the present utility model. Detailed Implementation
[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] See Figure 1 and Figure 2 As shown, the bathroom mirror of this utility model includes a mirror frame 1, a PET film 2, a silver cardboard 3, a waterproof film 4, and a sealant layer 5.
[0019] The mirror frame 1 provides structural support for the entire bathroom mirror. Frame 1 is composed of multiple I-shaped frame bodies 11 joined together to form the desired mirror frame. Two sets of opposing mirror support rods 12 are raised on the front surface of the I-shaped frame body 11, and the rear surface of the I-shaped frame body 11 is smooth and flush. The corners of the mirror support rods 12 are blunted and smoothed to ensure that the mirror support rods 12 can support the PET film. The tops of the mirror support rods 12 are at the same horizontal plane, allowing the PET film to form a mirror directly on the mirror support rods 12, thus avoiding the problem of uneven mirror surface caused by an incompletely flat frame, and the problem of not being able to guarantee a complete fit between the mirror film and the frame even if the frame is flat. The smooth and flush rear surface of the I-shaped frame body 11 provides a base for the adhesion of the silver cardstock. An adhesive layer is applied to the four sides and the rear surface of the mirror frame 1. A metal electroplating layer is deposited on the back of the PET film. After being stretched in all directions with a tensile tension of 2-10 Newtons by mechanical equipment, the mirror support rods 12 on each side are stretched tightly and the PET film is attached to the adhesive layer on the sides of the frame.
[0020] The PET film is stretched to form a mirror on the front surface of the eyeglass frame. Silver cardstock is attached to the adhesive layer on the back surface of the eyeglass frame. The edges of the silver cardstock meet the edges of the PET film. The silver cardstock closes the entire back surface of the eyeglass frame, achieving a complete seal inside the frame through the action of the silver cardstock and PET film. The silver cardstock is lightweight, does not increase the overall weight of the mirror, and enhances the overall aesthetics. A waterproof film 4 is attached to the back surface of the silver cardstock 3, protecting it while further preventing moisture from entering the eyeglass frame. A sealant layer (preferably a sealing aluminum foil tape layer) is applied to the edges of the silver cardstock 3 and the PET film, sealing the junction between the silver cardstock and the PET film. Figure 3 As shown. At the same time, the silver cardstock also enhances the aesthetics, allowing for customization of specific patterns according to customer needs.
[0021] In addition, see Figure 2 As shown, in this embodiment, a sealing strip 111 is provided inside the I-shaped frame body 11 to form two independent sealed spaces 112. The magnetic or rotating fastening structure 6 is set on the side wall of one of the sealed spaces 112 by rivets, and is not connected to the space between the frames, so as to prevent moisture from entering the space between the frames through the rivets and thus oxidizing the back surface of the PET mirror.
[0022] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of this utility model. All equivalent changes and modifications made to this utility model by those skilled in the art should fall within the scope of the appended claims.
