FIG. 2: a top view of a breathable waterproof rubber plug;
FIG. 3: fig. 2 is a sectional view a-a.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Specific example 1: please refer to fig. 1 to 3, in the embodiment of the present invention, a breathable waterproof rubber plug, include with flat plate collector frame cartridge complex cylinder 1, the inside air cavity 101 that runs through cylinder 1 that is equipped with of cylinder 1, one side of cylinder 1 is connected with ventilative cap 2, ventilative cap 2 is cylinder 1 structure, ventilative cap 2 is inside to be equipped with bleeder vent 201, bleeder vent 201 runs through the upper and lower both ends that pierce through ventilative cap 2, the one end and the bleeder vent 201 intercommunication of air cavity 101, bleeder vent 201 transverse section structure is rectangle form opening, and at the lateral wall of column structure, the opening contrast circular opening area of rectangle form is great, helps the external discharge of gas and liquid.
The joint of the ventilation cap 2 and the column body 1 is an umbrella-shaped connecting part 3, the outer diameter of the umbrella-shaped connecting part 3 is gradually increased from inside to outside along the axial direction of the column body 1, and the umbrella-shaped connecting part 3 is correspondingly inserted into the outer frame of the flat plate collector. The connection part of the umbrella-shaped connecting part 3 and the breathable cap 2 is provided with a clamping groove 4 clamped with the outer frame of the flat plate collector, and the clamping groove 4 is in interference fit with the outer frame of the flat plate collector.
The air cavity 101 comprises a first exhaust cavity 101-1 and a second exhaust cavity 102, one end of the second exhaust cavity 102 is communicated with the first exhaust cavity 101-1, the other end of the second exhaust cavity 102 is communicated with an air vent 201, and the diameter D of the first exhaust cavity 101-11Is smaller than the diameter D of the second exhaust cavity 1022. Due to the diameter D of the first exhaust chamber 101-11Is smaller than the diameter D of the second exhaust cavity 1022The step is formed at the joint of the first exhaust cavity 101-1 and the second exhaust cavity 102, when rainwater enters from the second exhaust cavity 102, the rainwater cannot continuously flow into the heat collector due to the blocking of the step, so that the rainwater flows out of the second exhaust cavity 102 to the ventilating cap 2 and is discharged outwards through the ventilating hole 201, and the design of the air cavity 101 can ensure that a dry environment is kept in the heat collector, and the rainwater is prevented from entering.
