[0031] Example

[0032] like Figures 1-4 As shown, this application proposes a moisture-proof wooden door, including a wooden door body 1. The bottom end of the wooden door body 1 has a U-shaped groove 2. A bottom protective plate 3 is fixedly connected to the four sides and the bottom end of the U-shaped groove 2. The bottom protective plate 3 is fixedly connected to the U-shaped groove 2 with glue. The four sides and the bottom protective plate 3 together form a complete protective shell, which can protect the bottom end and the four sides of the bottom of the wooden door body 1. The bottom protective plate 3 is a high-performance building material, which not only has waterproof and moisture-resistant properties, but also has a stable structure and is not easily deformed. It can provide multiple protections for the wooden door body 1 when set at the bottom.

[0033] Furthermore, a ventilation groove 4 is provided at the bottom of the wooden door body 1; mesh panels 6 are fixedly connected to both sides of the ventilation groove 4, and several ventilation control structures 7 are rotatably connected to both sides of the bottom protective plate 3. The ventilation control structure 7 includes a circular groove 71 on both sides of the bottom protective plate 3, with a circular piece 72 rotatably connected within the circular groove 71. A pair of strip-shaped through-holes 73 are provided on the circular piece 72, which are not easily separated from the circular groove 71. If ventilation and dehumidification of the bottom of the wooden door body 1 are required, the circular piece 72 is rotated 90 degrees so that the two strip-shaped through-holes 73 align with the mesh panel 6. Because ventilation control structures 7 are provided on both sides, air can achieve a certain convection effect within the ventilation groove 4 during ventilation, thus removing accumulated moisture from the bottom of the wooden door body 1 and keeping it dry. When the two strip-shaped through-holes 73 are in a left-right position, the ventilation groove 4 is sealed; when the two strip-shaped through-holes 73 are in an up-down position, the ventilation groove 4 is open to the outside. The ventilation control structure 7 can be operated periodically according to the environment in which it is used.

[0034] In this embodiment, the inner walls on both sides of the ventilation slot 4 are provided with several corresponding grooves, and a reinforcing plate 5 is inserted into each pair of grooves. The several reinforcing plates 5 can support the bottom of the wooden door body 1, keeping the bottom protective plate 3 in a strong supporting state.

[0035] It should be noted that the ends of several ventilation control structures 7 and several reinforcing plates 5 are staggered. After rotating the circular piece 72 by ninety degrees, the two strip-shaped through slots 73 are connected to the cavity of the ventilation slot 4.

[0036] Furthermore, the wooden door body 1 includes a door panel 101, the outer surface of which is coated with a waterproof coating 102, and the outer surface of the bottom protective plate 3 is also coated with a waterproof coating 102, for overall protection of the door panel 101. The bottom protective plate 3 is made of HPL (High-Pressure Laminate) board, and the waterproof coating 102 is polyurethane varnish. Polyurethane varnish can isolate moisture in the air and protect the door panel, but it will gradually lose its waterproof performance in severely humid environments. This application further enhances the waterproof effect by wrapping the bottom of the door panel with a bottom protective plate 3.

[0037] The working principle of this embodiment is as follows: This application opens a U-shaped groove 2 at the bottom of the wooden door body 1, and glues a bottom protective plate 3 to the four sides and bottom of the U-shaped groove 2. The bottom protective plate 3 has very good waterproof performance and high impact resistance. The outer surfaces of the wooden door body 1 and the bottom protective plate 3 are flat, which will not affect the appearance structure of the entire door. In a humid environment, it can significantly extend the service life of the wooden door. In addition, the bottom protective plate 3 also has very good impact resistance and can protect the wooden door (because people's feet will have more contact with the bottom of the door during use).

[0038] By opening a ventilation groove 4 on the inner side of the bottom of the wooden door body 1, and setting a ventilation control structure 7 that can communicate with the ventilation groove 4 on the bottom protective plates 3 on both sides, the circular discs 72 can be rotated periodically to ventilate the bottom of the wooden door body 1 in a humid environment. By rotating several circular discs 72 by 90 degrees, the two strip grooves 73 are aligned with the corresponding mesh plates 6, so that the ventilation grooves 4 are ventilated and kept dry, which further plays a role in moisture prevention.

[0039] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
