Detailed Description

The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 7, the liquid blocking device for a vent valve according to the present embodiment includes a housing 2 inserted into a vent valve 1, both left and right sides of the housing 2 are opened, a through gas flow passage is formed in the housing 2, a soft liquid blocking diaphragm 3 is installed in the gas flow passage, the liquid blocking diaphragm 3 is made of silica gel, a cross slit 4 is formed in the liquid blocking diaphragm 3, and the cross slit 4 tends to be closed naturally.

The ventilation valve 1 comprises a valve body 5 with openings on the left and right sides, a ventilation film 6 is arranged in the valve body 5, the ventilation film 6 is an existing product and is also called a waterproof ventilation film or breathing paper, the shell 2 comprises a first shell 7 and a second shell 8, the left and right sides of the first shell 7 and the second shell 8 are open, the first shell 7 is provided with an inserting sleeve 9 matched with the left opening of the valve body 5, the second shell 8 is provided with a first clamping convex edge 10, the inner wall of the left opening of the first shell 7 is also provided with a second clamping convex edge 11 matched with the first clamping convex edge 10, the left opening of the second shell 8 is provided with a cross-shaped grating 12, the right opening of the second shell 8 is internally provided with a third clamping convex edge 13, the liquid barrier diaphragm 3 is provided with a clamping groove 14 matched with the third clamping convex edge 13, the clamping groove 14 is annular, the first shell 7, the second shell 8 and the liquid barrier diaphragm 3 which are separated from each other facilitate the cleaning and replacement of the liquid barrier diaphragm 3, is favorable for prolonging the service life of the liquid barrier.
