Description

Technical Field

[0001] This application belongs to the field of diving breathing apparatus technology, and specifically relates to a diving breathing apparatus with an underwater switchable oxygen supply pump. Background Technology

[0002] When divers are deep-sea diving, they need oxygen supply equipment to breathe. The traditional oxygen supply equipment is a backpack oxygen cylinder, which is carried by the diver underwater. Although it can meet the needs of underwater breathing, the backpack oxygen cylinder has a limited oxygen storage capacity and is heavy, so it cannot be used for a long time and hinders the diver's underwater activities. There is another type of diving breathing apparatus that can be separated from the body. Its oxygen supply unit can float on the water surface and supply oxygen to the diver through an air supply tube that can go down with the diver. For example, the prior art discloses a diving respirator with publication number CN217074756U. This respirator includes a housing, inside which are installed a battery, a drive unit, and a cylinder head. A cover is located on top of the housing, and a magnetically controlled receiving switch is installed inside the cover. A sliding electromagnetic switch is installed on the surface of the cover. Although this diving respirator can control the power supply to the drive unit, battery, and cylinder head inside the housing by using the magnetically controlled receiving switch inside the housing in conjunction with the sliding electromagnetic switch on the surface of the cover, thus replacing the existing method of connecting wires for power supply, and can cut off the power to the drive unit, battery, and cylinder head inside the housing when the cover is opened, thereby reducing the number of openings in the diving respirator's cover and reducing the risk of water leakage, it has the following problems: Because it is a single-cylinder design, it is difficult to adjust the oxygen supply according to the diver's diving depth or diving time; and the switch for controlling the oxygen supply is located on the surface of the cover, making it impossible for the diver to control or adjust it underwater, which is not conducive to the diver controlling the respirator according to the needs of the diving state. Summary of the Invention

[0003] Based on the aforementioned technical needs, this application provides a diving respirator with an underwater switchable oxygen pump, which can solve the problems of existing technologies that make it difficult to adjust the oxygen supply according to the diver's diving depth or diving time, and that the switch for controlling the oxygen supply is located on the surface of the tank cover, making it impossible for the diver to control or adjust it underwater, which is not conducive to the diver controlling the respirator according to the needs of the diving state.

[0004] To achieve the above objectives, the technical solution of this application is as follows:

[0005] A diving breathing apparatus with an underwater switchable oxygen pump includes a floating body. The top of the floating body has a battery compartment and a cover.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limitations on this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0025] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present application will be further described in detail with reference to specific embodiments.

[0026] This application discloses a diving respirator with an underwater switchable oxygen pump. The diving respirator includes a floating body 10 capable of floating on the water surface. A battery compartment 11 and a cover plate 12 are embedded at the top of the floating body 10. The battery compartment 11 contains a power source for outputting electrical energy, such as a rechargeable battery. The cover plate 12 is a sealable cover 1233 that fits onto the surface of the battery compartment 11 to prevent the power source from coming into contact with water. A first switch 121 and an extension wire are provided at the top of the cover plate 12, and a second switch is provided at the other end of the extension wire. The bottom of the floating body 10 is provided with a main oxygen pump 15, at least one auxiliary oxygen pump 16, an air tank 17, and a breathing tube 18 connected to the air inlet of the air tank 17. The air outlets of the main oxygen pump 15 and the auxiliary oxygen pump 16 are both connected to the air inlet of the air tank 17. The main oxygen pump 15 is electrically connected to the power source through the first switch 121. The auxiliary oxygen pump 16 is electrically connected to the second switch and the power source through the extension wire.

[0027] In a preferred embodiment, both the first switch 121 and the second switch are waterproof switches. Since the first switch 121 is located on the upper part of the cover plate 12, and the upper part of the cover plate 12 has short contact time with water and generally does not bear water pressure, the first switch 121 only needs to have a splash-proof function, and its waterproof rating should be at least IPX4, such as the waterproof switch with publication number CN113593950B, whose housing is fixed to the surface of the cover plate 12, with its switch button located at the top of the cover plate 12. The second switch, however, needs to be carried underwater by the diver under the extension of the extension cord and needs to withstand water pressure at a certain depth; its waterproof rating is also important. The rating must reach IP68, and to prevent accidental underwater activation, a submersible switch for underwater robots or an M8 underwater switch can be selected. The length of the extension cable can be set according to the diver's diving depth, such as 5 to 30 meters. The connection between the extension cable and the second switch and the auxiliary oxygen pump 16, and the connection between the first switch 121 and the main oxygen pump 15, must be sealed and waterproof, such as by wrapping the wiring terminals with waterproof filler glue coating and / or covering the wiring terminals with waterproof heat shrink tubing. The air outlets of the main oxygen pump 15 and the auxiliary oxygen pump 16 are connected to the air storage tank 17 through a three-way pipe, and the air supply pressure is stabilized through the air storage tank 17.

[0028] Using the above-mentioned diving breathing apparatus has at least the following beneficial effects:

[0029] When using the above-mentioned diving breathing apparatus, before entering the water, the diver first turns on the main oxygen pump 15 via the first switch 121. The main oxygen pump 15 is used to meet the diver's breathing needs in shallow waters, such as below 5 meters. Even if the main oxygen pump 15 fails to supply oxygen due to a malfunction, the diver can immediately start the auxiliary oxygen pump 16 to breathe, ensuring safety. When the diver dives to deeper waters, the diver can start the auxiliary oxygen pump 16 at any time via the second switch to increase the oxygen supply and pressure. While meeting the needs of deep diving, it allows the diver to easily turn the auxiliary oxygen pump 16 on and off at any time according to the diving depth to adjust the oxygen supply and pressure, and to provide stable oxygen supply through the air tank 17 and breathing tube 18. This not only improves the reliability of oxygen supply, but also helps to reduce the oxygen supply energy consumption of a single pump and extend the oxygen supply time of the diving breathing apparatus.

[0030] Based on the above embodiments, this application also provides further embodiments to improve the above-described diving breathing apparatus.

[0031] Preferably, to facilitate the replacement of extension cords of different lengths, the above-mentioned power supply is electrically connected to the output terminal wire, and one end of the output terminal wire extends through the cover plate 12 to the top of the battery compartment 11. One end of the extension cord is connected to the output terminal through a waterproof aviation plug 19. By inserting or unplugging the waterproof aviation plug 19, the electrical connection between the second switch and the power supply is disconnected, so as to facilitate the replacement of extension cords of different lengths or to facilitate the storage of the extension cord when the diving breathing apparatus is not in use. The waterproof characteristics of the waterproof aviation plug 19 ensure that the connection between the output terminal wire and the extension cord meets the waterproof requirements.

[0032] In this embodiment, a right-angle bend 122 is provided at the top of the cover plate 12. One end of the output wire passes through the right-angle bend 122 and extends in a direction parallel to the horizontal plane of the cover plate 12. The right-angle bend 122 can fix the bending direction of the output wire and prevent the output wire from being repeatedly bent in different directions during the process of divers dragging the extension wire, thus accelerating aging.

[0033] Furthermore, in order to ensure that the waterproof aviation plug 19 remains fixed in position relative to the cover plate 12 during use and to prevent the waterproof aviation plug 19 and the output cable from being dragged or scraped by horizontal wind, thus causing the connection to loosen, a limiting box 123 is provided at the top of the cover plate 12, and the right-angle elbow 122 is located at the bottom of the limiting box 123. A snap-fit ​​groove 1231 is provided on the side of the limiting box 123 opposite to one end of the right-angle elbow 122. The snap-fit ​​groove 1231 fits with the waterproof aviation plug 19 and can snap the waterproof aviation plug 19 axially to prevent the waterproof aviation plug 19 from being easily moved.

[0034] In this embodiment, to prevent water from splashing onto the surface of the cover plate 12 and then seeping into the battery compartment 11 along the right-angle bend 122, a flexible sealing gasket 1232 is laid on the top of the limiting box 123 along the axial direction of the side wall. The flexible sealing gasket 1232 is made of silicone or rubber, etc. A sealing cover 1233 is provided on the side of the limiting box 123 that is away from the snap-fit ​​groove 1231. Buckles are provided on both sides of the sealing cover 1233. The sealing cover 1233 can be closed with the top of the limiting box 123 through the buckles, which can prevent water from seeping into the battery compartment 11 through the limiting box 123 and the sealing cover 1233.

[0035] Furthermore, to prevent excessive pressure on the left or right side of the floatable body 10 when divers drag the extension cable and snorkel 18, which could cause the floatable body 10 to become unbalanced or capsize, a limiting hole 101 is provided between the top and bottom of the floatable body 10 on both sides. One end of the extension cable and snorkel 18 extends downward through the limiting hole 101. At least part of the extension cable and snorkel 18 has a spiral stretchable structure, which can not only buffer the pulling force of the diver on the starting end of the extension cable and snorkel 18, but also shorten the relative length of the extension cable and snorkel 18, making it easier to store and carry.

[0036] To facilitate the diver's access to the second switch underwater, a limiting fastener 181 is provided at one end of the snorkel 18 adjacent to the second switch (i.e., the end of the snorkel 18) to secure the second switch. Specifically, the limiting fastener 181 is a fixing rod, one end of which is tightly fitted into the snorkel 18, and the other end is provided with a slot that engages with the second switch. The second switch includes a waterproof switch as disclosed in CN215644224U.

[0037] In a preferred embodiment, the top of the floating body 10 is provided with a first air inlet pipe 124 and a second air inlet pipe 125. Specifically, the air inlets of the first air inlet pipe 124 and the second air inlet pipe 125 extend vertically upward from below the cover plate 12 to above the cover plate 12, respectively. The air outlet of the first air inlet pipe 124 is connected to the air inlet of the main oxygen pump 15, and the second air inlet pipe 125 is connected to the air inlet of the auxiliary oxygen pump 16. The two air inlet pipes supply air to the main oxygen pump 15 and the auxiliary oxygen pump 16 respectively, and can prevent water from entering the air pump to a certain extent.

[0038] Furthermore, the outer surface of the floating body 10 is boat-shaped, which can improve buoyancy and floating stability, making the floating body 10 less prone to capsizing.

[0039] By combining the various structures and features in the above embodiments, the corresponding functions of the above-mentioned diving breathing apparatus with an underwater switchable oxygen pump have been improved, and the waterproofness, adaptability and stability of its key components during use have been enhanced, enabling it to serve diving projects more reliably.

[0040] Obviously, the above embodiments of this application are merely examples for clearly illustrating this application, and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
