Description

Technical Field

[0001] The utility model relates to the technical field of diving equipment, in particular to a breathing tube with improved use safety. Background Art

[0002] As living standards gradually improve, more and more people begin to pay attention to improving the quality of life. Appropriate outdoor sports can relieve physical and mental stress and are beneficial to health. At present, snorkeling has become one of the favorite and respected activities of young people. However, snorkeling has certain risks, and the breathing tube is one of the necessary equipment for snorkelers.

[0003] In the prior art, for example, a Chinese utility model patent with publication number CN208746218U discloses a breathing tube with an adjustable buckle position, including a tube head, a tail tube, a bellows tube, an outer tube body, a mouthpiece and a buckle, wherein the tube head, the tail tube, the bellows tube, the outer tube body and the mouthpiece are connected in sequence; a connecting strip is integrally formed at the lower end of the tail tube, and a gap is provided between the connecting strip and the outer wall of the tail tube, wherein a snap-on rack is provided on the inner wall of the connecting strip, and a buckle is connected to the connecting strip, and the buckle includes a connecting seat and a buckle ring. A Chinese utility model patent with publication number CN204956888U discloses a breathing tube for diving, including a tube head, a suction tube, a threaded tube, a tube tail and a mouthpiece that are connected in sequence, and also includes a cavity provided on the inner side wall of the tube head and provided with a drainage port, a round floating ball accommodated in the cavity, and a sealing ring sleeved on the air inlet and outlet above the cavity, and when the floating ball floats up, it acts with the sealing ring to seal the air inlet and outlet. These breathing tubes generally use bellows tubes or threaded tubes to achieve a certain degree of expansion or folding, and the expansion range is limited, which cannot meet the diving depth requirements of snorkelers within a certain range. They are dangerous and cannot meet the increasingly high requirements of snorkelers for breathing tubes. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a breathing tube that is safer for snorkelers to use by adjusting the length of the breathing tube body.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] To facilitate understanding of this embodiment, a breathing tube with improved safety of use disclosed in an embodiment of the utility model is first introduced in detail.

[0028] Example:

[0029] like Figure 1 and Figure 2 As shown, the present application is a breathing tube with improved safety in use, comprising a tube head 100, a tube body 200 and a mouthpiece 300 that are interconnected in sequence, the tube body 200 comprising a curved tube body 201 connected to the tube head 100 and a retractable straight tube body 202, the straight tube body 200 comprising an inner tube body 203 and an outer tube body 204, the inner tube body 203 being slidably connected to the outer tube body 204, specifically, the inner tube body 203 is connected to the mouthpiece 300, and the outer tube body 204 is connected to the curved tube body 201, the inner tube body 203 can slide back and forth in the sliding cavity 205 of the outer tube body 204 to achieve extension and contraction of the straight tube body 200, therefore, the snorkeler can adjust the length of the tube body 200 by adjusting the inner tube body 203, so that the tube body 200 can be greatly retracted and retracted, thereby meeting the snorkeler's snorkeling depth requirements within a certain range and improving the safety of use of the snorkeler.

[0030] Specifically, the inner tube body 203 includes a large diameter portion 2031 and a small diameter portion 2032. The large diameter portion 2031 can slide along the sliding cavity 205 of the outer tube body 204, thereby realizing the extension and contraction of the straight tube body 202. Two guide rails 2033 are arranged on the outer wall surface of the large diameter portion 2031. The two guide rails 2033 slide in corresponding guide grooves 2041 on the inner wall surface of the sliding cavity 205 of the outer tube body 204. By guiding the guide rails 2033 in the guide grooves 2041, the guide rails 2033 move along a specified trajectory, thereby improving the accuracy and stability of the movement of the inner tube body 203 relative to the outer tube body 204.

[0031] As a preferred embodiment of the present application, a limiting portion 2042 is provided at the port of the free end of the outer tube body 204 to prevent the inner tube body 203 from sliding out of the outer tube body 204. Therefore, when the snorkeler pulls the inner tube body 203 to the free end of the outer tube body 204, the large diameter portion 2031 is restricted by the limiting portion 2042 and cannot slide out of the outer tube body 204. At this time, the length of the tube body 200 reaches the longest.

[0032] As a preferred embodiment of the present application, a sealing cap 2043 threadedly connected to the outer tube 204 is provided at the free end of the inner tube 203 near the outer tube 204, and a tube sealing ring 2044 is also provided between the sealing cap 2043 and the free end of the outer tube 204. The design of the sealing cap 2043 and the tube sealing ring 2044 prevents water from entering the tube 200 from the connection between the inner tube 203 and the outer tube 204. In addition, when the breathing tube of the present application is not in use, the sealing cap 2043 is unscrewed, the inner tube 203 is extended to the end of the sliding cavity 205 of the outer tube 204, and the sealing cap 2043 is tightened, so that the length of the breathing tube of the present application is the shortest, which is convenient for snorkelers to store and transport.

[0033] Specifically, the pipe head 100 has a cavity 101, which is connected to a drain port 102 on the side wall of the pipe head 100. An air inlet and outlet 103 is arranged above the cavity 101. A float 104 capable of sealing the air inlet and outlet 103 is arranged in the cavity 101. A sealing ring 105 is arranged on the outer cover of the air inlet and outlet 103. Through the above-mentioned structural design, when the pipe head 100 enters underwater, water will flow into the cavity 101 from the drain port 102. When the water in the cavity 101 is filled to a certain height, the float 104 will rise due to the buoyancy of the water, thereby working together with the sealing ring 105 to seal the air inlet and outlet 103. At this time, water cannot enter the tube body 200 from the air inlet and outlet 103.

[0034] Specifically, the tube body 200 is provided with a water storage chamber 206 near the mouthpiece 300, and a one-way check valve 2061 for water discharge is provided at the lower end of the water storage chamber 206. Since the one-way check valve 2061 is provided at the lower end of the water storage chamber 206, when the water storage chamber 206 stores a small amount of water, the snorkeler exhales forcefully through the mouthpiece 300 to impact the one-way check valve 2061, and pushes it open, thereby discharging the water in the water storage chamber 206. During normal ventilation, the one-way check valve 2061 will not be pushed open at will due to the weak impact force, and at the same time, due to the effect of external water pressure, the one-way check valve 2061 is closely attached to the tube body 200, so that the external water will not enter the inside of the tube body 200 through the one-way check valve 2061.

[0035] As a preferred embodiment of the present application, a one-way air inlet valve 2034 is provided in the inner tube body 203 near the mouthpiece 300. Through the one-way air inlet valve 2034, the air exhaled by the snorkeler will only remain in the tube head 100. Since the volume of the tube head 100 is small, the amount of residual carbon dioxide is very small and can be ignored.

[0036] In summary, the present application solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable design, high safety, and strong practicality.
