The accompanying drawings illustrate one or more embodiments of the disclosure and together with the written description, serve to explain the principles of the disclosure. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment, and wherein:
The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
The side wall of the tube head is provided with a drain outlet 10, a cavity communicated with the drain outlet is provided inside, and a floating ball is provided in the cavity. The upper portion of the cavity is provided with an air inlet and outlet communicated with the tube body. When the tube head 102 stretches out of the water surface, the floating ball sinks into the lower portion of the cavity under the effect of gravity, and the tube body is communicated with the outside through the air inlet and outlet and the drain outlet for air exchange. When the tube head 102 sinks into the water, the water flows into the cavity from the drain outlet 10, and the floating ball blocks the air inlet and outlet due to the increase of buoyancy of water, such that water is prevented from entering the tube body 1.
In the present invention, a light warning device is provided in the tube head 102. A water sealing structure is adopted between the tube body and the tube head 2 to ensure that the light warning device in the tube head will not be damaged due to short circuit caused by water inflow. Similarly, a waterproof seal is also adopted between the cover body 2 of the tube head and the tube head 102.
The light warning device comprises a circuit board 4 fixed in the tube head, and an indicator lamp 6, an MCU 9, a power source 8, metal contact electrodes 5 and a vibration switch 7 mounted on the circuit board.
The function of the indicator lamp 6 is light warning, one or more indicator lamp may be provided, and preferably the indicator lamp is an LED lamp. The indicator lamp 6 has three working modes: (1) turn-off mode, (2) slow flashing mode and (3) SOS emergency rescue mode.
The power source 8 is used for supplying power for the whole light warning device. The power source may be a 3V button battery, and the endurance is about 120 h. When no power is available, it can be used again by replacing with a new battery. A rechargeable lithium battery may also be used, and in this case there is no magnetic suction charging port in the tube head.
The contact electrodes 5 are switch control of the indicator lamp 6 in the slow flashing mode. Two mounting holes 3 are provided in the cover 2, and the top ends of the metal contact electrodes respectively stretch out of the two mounting holes in the cover 2. A sealing structure is provided between each contact electrode and each mounting hole to avoid short circuit caused by leakage of water. The two metal contacts are also required to be insulated from each other.
When the cover 2 is not in contact with water, the two contact electrodes 5 are not conducted; when the cover 2 is immersed in water or the two contact electrodes are touched simultaneously by a wet hand, the contact electrodes are in a conducted state through the conductivity of water and form a current loop; when the MCU 9 receives an electric signal, the indicator lamp 6 is controlled to be in the slow flashing mode, at this moment the indicator lamp will flash intermittently, i.e., emit light like twinkling, and the interval time is controlled by the MCU 9. The slow flashing mode can provide a warning to nearby people and improve the safety of divers.
The vibration switch 7 is used for controlling the indicator lamp 6 to give out an SOS international standard rescue signal. The working principle of the vibration switch is that a conductive vibration spring and a trigger pin are accurately placed in the body of the vibration switch 7 and fixed by adhesives, the spring and the trigger pin are not conducted when there is no vibration, the spring jitters and contacts the trigger pin such that it is energized to generates a trigger signal when the spring is beaten and vibrates.
Under emergency, the tube head is beaten according to preset beat times, the vibration switch 7 vibrates under beating and is conducted, and the MCU 9 controls the indicator lamp 6 to be in the SOS emergency rescue mode and given out an SOS international standard rescue signal. When an athlete is in danger, he can give out the SOS international standard rescue signal in time to remind rescuers to rescue in time, thus avoiding dangerous accidents and ensuring the safety of athletes.
The MCU 9 is electrically connected with the indicator lamp 6, the power source 8, the contact electrodes 5 and the vibration switch 7 respectively. According to the situation of conduction of the metal contact switch and the vibration switch, the light state of the indicator lamp 6 is controlled to realize switching among the turn-off mode, the slow flashing mode and the SOS emergency rescue mode.
A GPS positioning device may also be mounted in the tube head. In case of emergency, the MCU controls the GPS to work to facilitate the search personnel to know the position of the diver.
As an alternative embodiment, the indicator lamp 15 may use a two-color lamp, a green lamp is on when oxygen is within the safe range, and a red lamp is on when oxygen is below the safe range.
The gas detection device may also comprise an alarm, which gives out an alarm signal when the oxygen exceeds the safe range to prompt the athlete to pay attention.
The power source 8 in the first sealing box may be a lithium battery or a rechargeable battery. In this case, a magnetic suction charging port 18 is provided in the first sealing box.
The tube body may further comprise an external second sealing box 19 connected thereto, the second sealing box is made of a transparent material, and a highly-identifiable object such as a red object or a luminous object is placed inside. The second sealing box may adopt a sealing cabin structure capable of being opened, which can be opened for placing a luminous or highly-identifiable object, so as to help to improve the identification rate among people.
The first sealing box and the second sealing box may be clamped on the tube body by adopting spring clips.
In the present invention, since a light warning device and a gas detection device are provided on the diving breathing tube, the safety capacity of the device is improved and the life safety of athletes is effectively guaranteed. In addition, in the present invention, the identification rate among divers is enhanced through the GPS and the second sealing box, which facilitates the searching by rescuers.
The above embodiments and drawings are only used for describing the concept of the present invention instead of limiting the present invention. The modifications made to the structure of the present invention, or the equivalent replacements made to some or all of its technical features, shall be included in the protection scope of the claims of the present invention.
