Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Figures 1 to 5, the breathing tube of the present invention includes a tube body 1 and a waterproof device 2, wherein:

The waterproof device 2 includes a base track 21 , a vacuum float 22 and a water retaining plate 23 . The base track 21 is in the shape of a two-stage hollow cylindrical tube with a small bottom and a big top. The inner wall of the upper end of the tube body 1 is provided with an annular groove 11, and the outer wall of the lower end (small hollow cylinder) of the base track 21 is provided with a corresponding clip. The ring 211, through the corresponding cooperation of the snap ring 211 and the annular groove 11, the lower end (small hollow cylinder) of the base track 21 is fixedly inserted into the upper end of the pipe body 1; the outer wall of the large hollow cylinder on the base track 21 The bottom is provided with an axially elongated guiding projection 212 . The above-mentioned vacuum floating ball 22 is composed of an outer cover 221, an upper cover 222, and a soft rubber part 223. The upper cover of the vacuum floating ball covered with glue and the outer cover of the vacuum floating ball are welded to make the upper cover 222 seal the outer cover 221 Further, a vacuum chamber 224 is formed. The soft rubber part 223 is disposed in the upper cover 222 and is used to form a sealing structure with the water blocking plate 23 . The lower end of the outer cover 221 of the above-mentioned vacuum floating ball 22 is provided with a strip-shaped guide groove 2211 corresponding to the strip-shaped guide protrusion 212, and the lower end of the vacuum float 22 is movably sleeved through the corresponding guide protrusion 212 and guide groove 2211. Outside the base track 21, it not only limits the sliding stroke of the vacuum floating ball 22, but also prevents the vacuum floating ball 22 from swinging left and right during the up and down sliding, ensuring the consistency of the vacuum floating ball 22 sliding up and down, reducing friction, and further The accurate positioning of the vacuum floating ball 22 and the water baffle 23 is guaranteed. The upper port of the vacuum floating ball 22 is higher than the upper port of the base track 21 . The water retaining plate 23 is separated into an upper gate plate 232 and a lower gate plate 233 by a leg 231, and the lower gate plate 233 is provided with a ventilation hole 234 corresponding to the upper port of the base track 21, and the lower end surface of the water retaining plate lower gate plate 233 is connected to The upper end surface of the base track 21 is sealed, glued or welded to prevent the water baffle from twisting, and the distance between the upper end surface of the vacuum floating ball 22 and the lower end surface of the upper gate 232 is less than or equal to that of the lower gate. The distance between the lower end surface of the plate 233 and the upper end surface of the base track 21, the axial length of the guide projection 212 is longer than the distance between the upper end surface of the vacuum floating ball 22 and the lower end surface of the upper gate 232, to prevent vacuum The guide protrusion 212 of the floating ball 22 breaks away from the guide groove 2211 of the base track 21 and cannot be returned accurately.

Referring again to Fig. 6 to shown in Fig. 9, the snorkel of the present utility model, when the people is snorkeling, the waterproof device 2 of pipe body 1 upper end floats on the water surface, and air passes through the upper port of vacuum floating ball 22, water retaining plate successively The ventilation hole 234 of the lower shutter 233, the base track 21 and the tube body 1 enter into the user's mouth. During the diving process, when the waterproof device 2 sinks to a certain depth, the vacuum floating ball 22 moves upwards along the guiding projection 212 of the base track 21 under the buoyancy of the water, and when it moves upwards to a certain distance, the water blocking The upper gate 232 of the plate 23 seals the upper port of the vacuum floating ball 22 to prevent sprays from entering the pipe body 1. Sealing prevents water flow back into the pipe body along the gap on the outer wall of the base track 21, so that the pipe body 1 is still a vacuum when submerged in water, forming a double-channel sealing structure to better achieve the sealing effect; that is, the upper port of the vacuum floating ball 22 Withstand the lower end surface of the upper flashboard 232 of the water retaining plate 23, and block water from entering the pipe body 1 through the upper flash plate 232 of the water retaining plate. The upper shutter 232 of the water retaining plate 23 , the lower shutter 233 and the soft glue 223 in the upper cover 222 of the vacuum float 22 can further play a sealing role. When the user floats up, the waterproof device floats up to a certain height, and the vacuum float 22 slides down along the guide projection 212 of the base track 21 under the action of its own gravity, and the upper port of the vacuum float 22 is connected to the water retaining plate 23. The lower end surface of the flashboard 232 is gradually separated, and the air can enter the guide shaft pipe from the air hole of the water retaining plate, thereby entering the pipe body, so the air re-enters the pipe body 1 and circulates again and again. After the user emerges from the water, he blows air with his mouth, and the water in the pipe body 1 moves upward along the air flow and is ejected from the upper port of the sponge float 4 .

The key point of the design of the utility model is that the vacuum floating ball moves up and down along the base rail, resulting in the sealing and separation between the vacuum floating ball and the water retaining plate, which can effectively prevent water from entering the pipe body from the nozzle during the diving process. Air can be inhaled when not diving to improve the safety of use

The above is only a preferred embodiment of a breathing tube of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, Equivalent changes and modifications all still belong to the scope of the technical solution of the present utility model.
