Problems solved by technology
[0002] In order to prevent the accumulation of moisture inside the decorative board and the change of external temperature from causing potential safety hazards and affecting the service life of the decorative board, the decorative board is generally provided with breathing holes, which are generally set on the surface of the decorative board. As a result, the ventilation and dustproof effect of the decorative board is poor, the construction is complicated, and the construction difficulty is increased; therefore, it is necessary to design a drainage device with a simple structure, convenient construction, waterproof, breathable and dustproof effect

Embodiment Construction
[0016] In the following, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand more clearly the technical idea claimed in the present invention.
[0017] Such as Figure 1-2 Shown is a shielding waterproof breathable valve of the present invention, which includes a horizontal block 1 and a vertical block 2 which are vertically intersected. The back and the front of the longitudinal block 2 are provided with an inclined through hole 3, the first orifice 31 of the inclined through hole 3 on the back of the longitudinal block 2 is higher than the second orifice 32 on the front of the longitudinal block 2, and the inclined through hole 3 is located on the front of the longitudinal block 2. The aperture of the first aperture 31 on the back of the longitudinal block 2 is larger than the aperture of the second aperture 32 on the front of the longitudinal block 2. The cross section of the oblique thr...

The invention discloses a shielding, waterproof and air-permeable valve. The valve comprises a transverse block and a longitudinal block which are vertically crossed, wherein an inclined through hole penetrating through the back and the front of the longitudinal block is formed in the longitudinal block, a first hole opening, located at the back of the longitudinal block, of the inclined through hole is higher than a second hole opening located in the front of the longitudinal block, and the hole diameter of the first hole opening, located at the back of the longitudinal block, of the inclined through hole is larger than that of the second hole opening located in the front of the longitudinal block. The valve can be mounted between decoration plates, has the advantages that moisture, vapor and air in the decoration plates can be discharged conveniently and the waterproof and air-permeable effects are good, can prevent dust from entering the decoration plates and is simple in structure and convenient to construct; problems that decoration plates are worse in air-permeable and dustproof effect, construction is complex and construction difficulty is increased due to the fact that air-permeable holes of the traditional decoration plates are generally formed in plate surfaces of the decoration plates are solved.
Description
technical field [0001] The invention relates to the technical field of decorative boards, in particular to a shielding, waterproof and breathable valve installed between decorative boards for draining moisture in the decorative boards. Background technique [0002] In order to prevent the accumulation of moisture inside the decorative board and the change of external temperature from causing potential safety hazards and affecting the service life of the decorative board, the decorative board is generally provided with breathing holes, which are generally set on the surface of the decorative board. As a result, the air permeability and dustproof effect of the decorative board are poor, the construction is complicated, and the construction difficulty is increased; therefore, it is necessary to design a drainage device with a simple structure, convenient construction, waterproof, breathable and dustproof effect. Contents of the invention [0003] Aiming at the deficiencies of...
