Description

M252649 IV. Creation Instructions (1) [Technical Field to which the New Type belongs This invention relates to the structure of a dry-type snorkel wave-proof head, in particular, a type of wave-proof head cover with a hollow and closed air chamber, and the bottom of the partition: a groove, which can The anti-wave head is maintained on the sea surface in a forward direction (or upright, and it is easy to discharge the seawater that has penetrated into the breathing tube. [Previous technology] $ ° Dry breathing tube is mainly used for divers to snorkel, in order for water to enter the breathing tube, Design a buoy in the wave-proof head. Use the buoyancy principle to close the water inlet so that the seawater cannot enter the breathing tube. = Li Zhi ^ ® Dashi Shibajiji g 円, there is a wide range of products in Xufang, as shown in Figure 1. Equipped with a straight vertical pontoon 101, the wave-proof head 200 in Figure 2 has a multi-legged vertical buoy 2001, and the figure ^ 3 0 0 has a peripheral vertical buoy 300m, and the wave-proof head in Figure 4. 〇00 has a ^ style ocean tube 401; the above wave-protection heads have the same common disadvantages, as follows ^ as follows: 1. When the tilt angle is too large, the pontoon can easily close the water inlet, so the shirt can effectively and smoothly divers Breathe 2. When the waves are too At this time, the buoy is not closed properly, and the seawater can easily enter the breathing tube. 3. When the seawater enters the breathing tube and wants to be discharged out of the tube, part of the seawater is returned due to the obstruction of the wave-proof head cover, causing the diver to constantly blow air. Draining water, which makes it difficult to drain water. = In view of this, the creator has accumulated years of experience in this trip, is refined = researched nine and tested and improved again, and now finally create a full and made a sample. Mouth 'provides a The new type of dry-type snorkel anti-wave head can eliminate the shortcomings of conventional products and improve the efficacy.

Page 5 M252649 IV. Creation Instructions (2) [New Content] The main purpose of the creation of Yuan Che 4 * Langtou is to provide a dry breathing tube air-proof chamber. The structure is improved, and the top of the head of the wave-proof head is set. —Hollow airtightness, no 不会 head on the sea—Keep straight (upright) position, lost; :: Jing closed too quickly or seawater is more likely to enter the breathing tube. The lack of conventional water shortage is less than 2 of the middle The bottom of the partition is provided with a number of water diversion grooves. When the sea is discharged into the breathing tube, the water diversion grooves can smoothly transport seawater 卞 ® to the outside without flowing back. Another purpose of the structural modification is to provide a side of the anti-wave head of a dry breathing tube, not I. The buoy of this creation is set beside the main body of the anti-wave head, which will hinder the diver from draining due to the resistance caused by the buoy. In order to allow your reviewing committee to have a further understanding of this creation, here is a detailed description of the diagram: [Embodiment]--Figure 5 ~ Figure 7, the inner edge ir 'of the nozzle 1 of the breathing tube 1 The mt card block ui can be inserted into the two holes 9 & 4 of the bottom end of the body 21 of the waveproof head. The waveproof head 2 is composed of the body 21, the pontoon 22, the partition 23 and the top cover 24. Among them, the body 2 丨 The connecting tube 2 connecting to the breathing tube i is equipped with a container 213 on the side for the tube 22 to be inserted into the 'through tube 212 and the container 213 are connected by a circular groove 214 at the top. Sides 2131 are provided on the sides to allow air to enter or flow in for the buoy 22 to float; the circular partition 23 can be inserted into the circular groove 214Θ of the main body 21, and the connecting pipe 231 at the bottom end can extend into the main body. In the valley chamber 213, a large area of hollow 232 beside the receiver 231 is in communication with the circular groove 214. When the wave prevention head 2 penetrates into the water surface, the buoy 22 can float up,

4. Creation instructions (3) The buoyancy problem and the water tightness 221 can block the pipe hole 233 at the bottom end of the takeover 231 to prevent the seawater in the chamber 2 1 3 from entering the through pipe 2 1 2 and flowing into the diver's password ( Figure 7) The internal thread 241 on the inner bottom of the top cover 24 can be bolted with the external thread 21 5 on the outer top of the body 21 °. A 10-shaped waterproof washer 2151 is placed under the external thread 21 5 of the main body. Above the thread 241, another 0-shaped waterproof gasket 2 is housed. The 411 waterproof gasket 2 1 5 1 and 2 4 1 1 have a water-stopping effect. It is characterized in that the top of the top cover 24 of the wave head 2 has a hollow and closed air chamber 242. Due to the arrangement of the air chamber 242, the buoyancy of the wave prevention head 2 on the sea surface can be increased to maintain the diver's breathing tube. The wave-proof head 2 always maintains the forward (upright) position, so that the tilt angle of the wave-proof head 2 is not too large, resulting in the lack of conventional products such as the buoy 22 closing too quickly or the seawater easily entering the breathing tube, to maintain the divers breathing smoothly. In addition, the water groove 234 (see figure 7) of the wave-proof head 2 partition plate 2 3, in case one exhales the seawater through the through pipe 21 2, the seawater exits the breathing tube 1 through the water diversion groove 234 By. The bottom is provided with several arc-shaped guides. When the seawater enters the breathing tube 1, the diving row is towards the side of the chamber 2 1 3 and the strand 21 3 1 can be discharged easily and without backflow.

Suspicious * In summary, the structure of the dry-type snorkel wave-proof head of this creation is improved, and it is placed on the side of the wave-proof head 'except that it will not cause the diver to form a hindrance when the water is drained by the diver ^ i for the wave-proof head on the sea _ Keep it in a straight position to prevent the sewage tank from closing too quickly or seawater easily entering the breathing tube. When seawater enters the breathing tube, the seam can be drained out of the breathing tube smoothly without backflow through the partition channel. Its practical effect is indisputable, and it has already complied with the provisions of the Patent Law.
