Detailed Description
The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.
Example 1: a breathable noise-reduction earplug comprises a hard tube 1, an operation air bag 2 fixed on the hard tube 1 and a response air bag 3 fixed on the hard tube 1, wherein the operation air bag 2 and the response air bag 3 can be fixed on the hard tube 1 in an adhesion mode. The response air bag 3 is arranged at one end part, such as the right end, of the hard tube 1, a vent hole 121 communicated with the inner cavity of the operation air bag 2 is arranged on the side surface of the hard tube 1, a vent hole 131 communicated with the inner cavity of the response air bag 3 is arranged on the side surface or the end part of the hard tube 1, a sealing screw rod 5 is arranged at the other end part (corresponding to the left end part) of the hard tube 1, so that the operation air bag 2 is sealed with gas, and the sealing screw rod 5 can also cut off an air flow channel between the operation air bag 2 and the response air bag; a porous airbag cover 4 is fixed to the surface of the response airbag 3 in an optional manner by adhesion.
Referring to fig. 2 to 3, the rigid pipe 1 includes a left end portion 11 having a stepped inner diameter, an intermediate portion 12, and a right end portion 13, and in fig. 2, the rightmost end of the right end portion 13 is narrower than the left end, which is not particularly effective. The left end portion 11 is provided with an internal thread engaged with the seal screw 5, and a vent hole 121 where the operation airbag 2 communicates with the hard tube 1 is provided in the intermediate portion 12. The sealing screw 5 comprises a thread part 51 and a top sealing part 52, the top sealing part 52 is wrapped with an elastic sealing layer 53, the thread part 51 is screwed on the internal thread of the left end part 11, so that the sealing screw 5 is connected on the hard tube 1, a sealed cavity is formed in the operation air bag 2, the response air bag 3 and the hard tube 1, the elastic sealing layer 53 is pressed against the middle part 12, and after the sealing screw 5 is screwed in and the elastic sealing layer 53 passes over the vent hole 121, the elastic sealing layer 53 can cut off an air flow channel between the operation air bag 2 and the hard tube 1. Thus, the internal thread of the hard tube 1 does not damage the elastic sealing layer 53 when the sealing screw 5 is operated; the threads, the side face of the threaded portion and the elastic sealing layer form a layer-by-layer air isolation effect, and the sealing effect on the vent hole 121 is good.
Referring to fig. 2-3, the length of the overseal 52 is greater than the length of the intermediate portion 12. Thus, the elastic seal layer 53 or the top seal portion 52 can be pressed against the side surface of the right end portion 13, and the sealing effect is further improved.
Referring to fig. 1-3, the seal screw 5 is further provided with a hand-held portion 54, and the hand-held portion 54 is provided on an end surface or a side surface of the threaded portion 51.
Preferably, the porous air bag cover 4 can be made of sponge materials, and can also be made of elastic cloth wrapped with cotton.
The use process of the breathable noise reduction earplug comprises the following steps: the sealing screw rod is rotated to enable the vent hole 121 to be in an unblocked state, the breathable noise reduction earplug is plugged into an ear, and in the plugging process, the gas in the response air bag is extruded into the operation air bag; after reaching a proper depth, the operation air bag is extruded to enable air in the operation air bag to enter the response air bag through the air hole 121, the hard tube and the air hole 131, the response air bag expands and is matched with the auricle to extrude the porous air bag sleeve to seal the auricle, at the moment, the hard tube is held by hand and the sealing screw is screwed inwards, and the sealing screw sequentially seals the air hole 121 and the hole on the end face of the right end part to form sealing. The porous air bag sleeve has the functions of ventilation, sound absorption, noise reduction and moisture absorption. If the breathable noise reduction earplug is to be taken down, the hard tube is held by a hand to rotate the sealing screw outwards, and when the vent hole 121 is not blocked, the plug is directly pulled out.
It is convenient for fill in the auricle, and has ventilative effect concurrently, and porous type gasbag cover still can absorb water simultaneously.
The present invention has been described in detail with reference to the accompanying drawings and embodiments, but those skilled in the art will understand that various specific parameters in the above embodiments can be changed without departing from the spirit of the present invention to form a plurality of specific embodiments, which are the common variation ranges of the present invention and will not be described in detail herein.
