When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0049] Please refer to Figure 1 , an embodiment of the present application provides a water-entry floating device 100. After the water-entry floating device 100 falls into water, it can automatically float. In this embodiment, the water-entry floating device 100 can be used to connect a mobile electronic device, such as a mobile phone, so as to facilitate salvaging a mobile electronic device that has fallen into water.

[0050] Please refer to Figure 1 、 Figure 2 and Figure 3 , the water-entry floating device 100 includes a first outer sleeve 10, an inner sliding tube 20, a water-soluble member 30, a gas-generating powder 40, and an airbag 50. Part of the inner sliding tube 20 is movably inserted into the first outer sleeve 10. The gas-generating powder 40 is disposed in the first outer sleeve 10, and the airbag 50 communicates with the inner sliding tube 20 and is exposed outside the first outer sleeve 10. The water-soluble member 30 is disposed between the inner sliding tube 20 and the external environment, so that water in the external environment can enter the inner sliding tube 20 after melting the water-soluble member 30, and then contact the gas-generating powder 40, thereby generating gas. The airbag 50 can receive the gas and expand and open. The expanded airbag 50 can float by buoyancy. In this way, the water-entry floating device 100 achieves the purpose of floating when encountering water.

[0051] In this embodiment, the first outer sleeve 10 is generally cylindrical, and the first outer sleeve 10 includes a first bottom plate 11 and a first side wall 12. The first side wall 12 surrounds one side of the first bottom plate 11 to form a first receiving space 13. That is, one end of the first outer sleeve 10 is open and the other end is closed.

[0052] The inner sliding tube 20 is generally cylindrical, and the inner sliding tube 20 includes a second bottom plate 21 and a second side wall 22. The second side wall 22 surrounds one side of the second bottom plate 21 to form a second accommodation space 23.

[0053] The inner sliding tube 20 is movably inserted into the first outer tube 10, and one end of the inner sliding tube 20 corresponds to the closed end of the first outer tube 10. The second accommodation space 23 communicates with the first accommodation space 13, and the first bottom plate 11 and the second bottom plate 21 are disposed at a relatively spaced interval. The second bottom plate 21 is provided with a through hole 211, and the airbag 50 is connected to the through hole 211. An opening 221 is formed through the second side wall 22, and the opening 221 communicates the second accommodation space 23 with the external environment, and the opening 221 is exposed in the first accommodation space 13. The opening 221 is used to allow water to flow from the external environment into the second accommodation space 23 and flow from the second accommodation space 23 to the gas generating powder 40 disposed in the first accommodation space 13.

[0054] The water-touching dissolving member 30 covers the opening 221 to block the direct communication between the second accommodation space 23 and the external environment. After the water-touching dissolving member 30 is dissolved in water, the water in the external environment can enter the second accommodation space 23 through the opening 221. Among them, the dissolution of the water-touching dissolving member 30 requires a long time and a large amount of water to be completely dissolved and open the opening 221, so as to prevent the airbag 50 from being accidentally opened due to non-falling water, such as rainwater. Among them, the material of the water-touching dissolving member 30 includes solid substances that dissolve in water immediately, such as effervescent tablets, polyvinyl alcohol films, methyl cellulose, polyvinylpyrrolidone, and polyethylene glycol.

[0055] In this embodiment, the water buoyancy device 100 further includes a second outer sleeve 60 and a connecting plate 64. The second outer sleeve 60 has openings at both ends, and one end of the second outer sleeve 60 is connected to one end of the first outer sleeve 10. The second outer sleeve 60 is sleeved on another part of the inner slide tube 20, and the inner wall of the second outer sleeve 60 is spaced from the outer wall of the inner slide tube 20 to form a first water guide groove 65. The connecting plate 64 is arranged on the outer side of the second outer sleeve 60. The connecting plate 64 is used to connect other devices (for example, a mobile phone, a watch, etc.). A first baffle 24 is arranged on the side of the inner slide tube 20 away from the second receiving space 23. A second baffle 61 is arranged inside the second outer sleeve 60, and the first baffle 24 and the second baffle 61 are arranged opposite to each other. The opening 221 is located between the first baffle 24 and the second baffle 61, and the water-contacting dissolving member 30 is located between the first baffle 24 and the second baffle 61. When water from the external environment enters through the first water guide groove 65 and gradually dissolves the water-dissolving member 30, water can enter the second receiving space 23 from the opening 221. The first baffle 24 and the second baffle 61 can limit the maximum movement range.

[0056] In this embodiment, the wall of the second outer sleeve 60 is further provided with a second water guide groove 66, one end of which is connected to the external environment, and the other end is provided corresponding to the water-contacting dissolving member 30. The second water guide groove 66 is provided so that when the first water guide groove 65 is blocked due to the obstruction of the second baffle 61, water from the external environment can reach the water-contacting dissolving member 30 through the second water guide groove 66.

[0057] In this embodiment, the first outer sleeve 10 further includes a first limiting ring 14, which is sleeved on the side of the first side wall 12 facing the first receiving space 13. The inner sliding tube 20 further includes a second limiting ring 25. The second limiting ring 25 is arranged on the side of the second side wall 22 away from the second receiving space 23, and the first limiting ring 14 and the second limiting ring 25 are arranged opposite to each other. The water buoyancy device 100 further includes an elastic member 62 and a plug body 63. One end of the elastic member 62 abuts against the second limiting ring 25, and the other end abuts against the first bottom plate 11. One end of the plug body 63 is fixed to the first bottom plate 11, and the other end can be movably inserted into the end of the second receiving space 23 away from the second bottom plate 21. Among them, the elastic member 62 is a compression spring.

[0058] See also Figure 3 and Figure 4, during actual use, when the water-soluble member 30 is dissolved in the water in the external environment and enters the second accommodation space 23, the elastic member 62 drives the inner sliding tube 20 to move away from the first bottom plate 11 by acting on the second limiting ring 25 until the first baffle 24 abuts against the second baffle 61, and the inner sliding tube 20 stops moving. At the same time, the plug body 63 slowly withdraws from the inner sliding tube 20, thereby creating a gap S between the plug body 63 and the inner sliding tube 20. The water in the second accommodation space 23 can flow through the gap S to the gas generation powder 40 located in the first accommodation space 13 and react to generate gas, thereby inflating the airbag 50.

[0059] In this embodiment, the water-entry floating device 100 further includes a sealing ring 70, and the sealing ring 70 is located between the first limiting ring 14 and the second limiting ring 25. The sealing ring 70 is sleeved on the inner sliding tube 20, and one side of the sealing ring 70 facing away from the inner sliding tube 20 is in close contact with the first side wall 12. In this way, the gas generated by the reaction of the gas generation powder 40 with water will not overflow from the gap between the first outer sleeve 10 and the inner sliding tube 20, but can only fill the airbag 50, improving the utilization rate of the gas generation powder 40.

[0060] In this embodiment, the cross-section of the inner sliding tube 20 is cylindrical, and the cross-section of the plug body 63 is wedge-shaped. The plug body 63 includes a first end 611 and a second end 612 opposite to the first end 611. The cross-sectional width of the first end 611 is smaller than the cross-sectional width of the second end 612, and the cross-sectional width of the second end 612 is substantially the same as the inner diameter of the inner sliding tube 20. In this way, when the elastic member 62 does not push the inner sliding tube 20, that is, when the water-soluble member 30 is not completely dissolved and part of the water-soluble member 30 still abuts between the first baffle 24 and the second baffle 61, the second end 612 blocks the inner sliding tube 20, so that a small amount of water in the second accommodation space 23 cannot enter the first accommodation space 13. When the elastic member 62 pushes the inner sliding tube 20, that is, when the water-soluble member 30 is completely dissolved, the second baffle 61 moves towards the first baffle 24, and a large amount of water enters the second accommodation space 23 and enters the first accommodation space 13 through the gap S.

[0061] In this embodiment, the gas generation powder 40 is filled between the elastic member 62 and the first side wall 12. The gas generation powder 40 specifically includes a mixture of sodium carbonate and an acidic substance, a mixture of citric acid and baking soda (sodium bicarbonate), a persulfate compound, a mixture of calcium hydroxide and an acidic substance, a mixture of potassium permanganate and hydrogen peroxide, and a mixture of an acidic carbonate and a solid acid.

[0062] In this embodiment, the airbag 50 is red, yellow, or orange, which is beneficial for high visibility in water, such that once the device floats, it can be quickly identified and located even under complex water quality or light conditions.

[0063] In this embodiment, the water-entry floating device 100 is designed to improve the visibility and recoverability of devices dropped into water, and is particularly applicable to mobile electronic devices such as mobile phones or tablet computers. The water-entry floating device 100 is particularly beneficial in outdoor activities such as boating, fishing, beach outings, water sports, etc., where there is a high risk of the device accidentally falling into water. The automatic floating characteristic of the water-entry floating device 100 can quickly bring the device dropped into water back to the water surface, thereby greatly reducing the risk of device loss and enabling the user to quickly recover their valuable items. In emergency rescue or search and rescue operations, the water-entry floating device 100 can also be used to mark devices or other important items, such as life-saving equipment, communication equipment, etc., for quick positioning in the water environment. Due to the eye-catching colors (such as red, yellow, orange) of the airbag 50, the device can be quickly identified even under adverse weather or low light conditions. In addition, the water-entry floating device 100 is also applicable to personal leisure and entertainment activities such as underwater photography, beach vacations, etc., providing additional safety protection for users. Its simple design and easy-to-operate characteristics make it an ideal accessory for any activity that may involve water.

[0064] The water-entry floating device 100 provided by this application has the following advantages:

[0065] (1) Quick response and automatic floating function: The water-soluble part 30 contained in the device quickly dissolves when it encounters water, allowing water to flow into the inner sliding tube 20 to contact the gas-generating powder 40, and quickly generating gas. This process ensures that the device can quickly respond when accidentally falling into water, timely bringing the connected device back to the water surface, effectively reducing the risk of item loss or damage.

[0066] (2) Compact structure and efficient space utilization: The designs of the first outer tube 10 and the inner sliding tube 20 make clever use of space, making the entire water-entry floating device 100 have a compact structure, which is convenient for carrying and installation. The mutual nesting of the first outer tube 10 and the inner sliding tube 20 not only saves space but also increases the overall stability and durability of the water-entry floating device 100.

[0067] (3) Reliable waterproof and anti-mis-touch mechanism: The setting of the water-soluble part 30 effectively prevents mis-triggering under non-immersion conditions such as rainwater, ensuring that the device only starts when it actually falls into water. This increases the reliability of the device and avoids unnecessary gas release and inflation of the airbag 50.

[0068] (4) Enhanced safety performance: After being inflated, the airbag 50 can significantly increase the buoyancy of the device. Even in complex water environments or poor visibility conditions, it can quickly bring the device to the water surface and keep it visible, thus improving safety and recovery efficiency.

[0069] (5) Wide applicability: Due to the universality of the structure design of the water-entry floating device 100, the water-entry floating device 100 can be widely applied to a variety of small electronic devices and personal items, and is particularly suitable for use in outdoor activities, water sports and other occasions.

[0070] The above embodiments are only used to illustrate the technical solutions of the present application rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
