[0025] like Figure 1 to Figure 4As shown, it shows the structure of a preferred wearable lifesaving device 100 of the utility model. Among them, the wearable lifesaving device 100 may include a shell 10, a main gas cylinder 20, a sealing member 30 and a wearing member 50. The shell 10 is formed with an opening 11 and a cavity 12 connected to the outside through the opening 11, and at least part of the shell 10 forming the cavity 12 is an elastic shell. The main gas cylinder 20 is arranged in the cavity 12 corresponding to the opening 11, and compressed gas is stored in the main gas cylinder 20, and the gas outlet of the main gas cylinder 20 is sealed by a first water-soluble tablet 21, and the first water-soluble tablet 21 is built with a first spring 22 in a compressed state. The sealing member 30 is arranged on the main gas cylinder 20 corresponding to the opening 11. The wearing member 50 is arranged on the outside of the shell 10 and is worn by the user. Water can enter the cavity 12 from the opening 11 and dissolve the first water-soluble tablet 21 to connect the main gas cylinder 20 with the cavity 12 and release the first spring 22. The first spring 22 can be released to a released state, and drives the main gas cylinder 20 to move toward the opening 11, so that the sealing member 30 on the main gas cylinder seals the opening 11, so that the cavity 12 forms a closed cavity. The compressed gas in the main gas cylinder 20 can inflate the closed cavity, so that the elastic shell expands to an expanded state and provides buoyancy to the user. Figure 4 As shown, not only the first spring 22 in the released state is shown, but also the state of the housing 10 after being inflated. Figure 4 It can be seen that the cavity 12 of the shell 10 becomes larger after being inflated, thereby providing buoyancy for a drowning user.

[0026] Preferably, the elastic shell portion of the shell 10 is made of elastic materials such as elastic rubber, but the present invention is not limited thereto.

[0027] exist Figure 1 In the preferred embodiment shown, the housing 10 may include, for example, a front portion 10a, a side portion 10b, and a back portion 10c, wherein the entire housing 10 may be made of elastic rubber. It is understood that, in other embodiments, only the side portion 10b and the front portion 10a of the housing 10 may be designed as elastic housings, while the back portion 10c of the housing 10 may be designed as a hard material, which is also not a limitation to the present invention, as long as the housing 10 has an elastic housing portion and can be inflated.

[0028] In some embodiments of the present invention, Figure 1As shown, the wearable lifesaving device 100 may further include an outer layer of rice paper 13, which is coated on the outer side of the shell 10. By coating the outer layer of rice paper 13 on the outer side of the shell 10, the outer shape of the entire wearable lifesaving device 100 can be better maintained when the area of ​​the elastic shell portion of the shell 10 is large. Moreover, the outer layer of rice paper 13 will dissolve quickly when a drowning event occurs, and will not prevent water from entering the cavity 12 from the opening 11, that is, it will not affect the normal use of the wearable lifesaving device 100.

[0029] like Figure 1 As shown, and combined with reference Figure 2 and Figure 3 Preferably, the opening 11 can be arranged on the front of the housing 10, for example, at the center of the front of the housing 10; the wearing piece 50 can be arranged on the back of the housing 10. However, it can be understood that the location of the opening 11 and / or the wearing piece 50 can be designed as needed, which is not a limitation of the present invention.

The wearable lifesaving device 100 of the badge-like structure of the utility model is particularly suitable for children. However, it is understandable that the wearing piece 50 can also be other wearable structures such as Velcro or a bracelet, and the wearing position is not limited to the above positions, that is, it can also be worn on the hand through a bracelet, etc., and the user is not limited to children, which is also not a limitation to the utility model.

[0031] In some embodiments of the present invention, the sealing member 30 may be, for example, an elastic sealing member (e.g., made of elastic rubber), and has a connecting portion 31 connected to the main gas cylinder 20 and a protruding portion 32 protruding from the connecting portion 31 toward the opening 11, which may be protruding in an arc shape. Preferably, the outer diameter d2 of the protruding portion 32 is greater than the diameter d1 of the opening 11, and the connecting portion 31 matches the opening 11 (e.g., the outer diameter of the connecting portion 31 may be equal to the outer diameter of the opening 11), but the present invention is not limited thereto.

[0032] In some embodiments of the present invention, Figure 1As shown, the wearable lifesaving device 100 may also include an auxiliary gas cylinder 40 disposed in the cavity 12. Compressed gas is stored in the auxiliary gas cylinder 40 and its gas outlet is sealed by a second water-soluble tablet 41. Water can enter the cavity 12 from the opening 11 and dissolve the second water-soluble tablet 41 to connect the auxiliary gas cylinder 40 with the cavity 12, and the compressed gas in the auxiliary gas cylinder 40 can inflate the closed cavity so that the elastic shell expands to an expanded state and provides buoyancy for the user. Preferably, the second water-soluble tablet 41 may also be built with a second spring 42 in a compressed state, wherein, after the second water-soluble tablet 41 is dissolved, the second spring 42 can be released to a released state and drive the auxiliary gas cylinder 40 to move to expand the cavity 12. By setting the auxiliary gas cylinder 40, the speed of inflation can be accelerated.

[0033] Preferably, a plurality of auxiliary gas cylinders 40 may be designed to be evenly spaced around the outer circumference of the main gas cylinder 20. Figure 5 and Figure 6 As shown, an opening can be set at the center of the front side of the shell 10, a main gas cylinder 20 is located at the center of the cavity 12 corresponding to the opening, and three auxiliary gas cylinders 40a, 40b, 40c are arranged on the periphery of the main gas cylinder 20 in a triangle.

[0034] exist Figure 1 In the embodiment shown, the gas outlet of the main gas cylinder 20 is fixedly connected (including but not limited to bonding) to the inner wall of the cavity 12 corresponding to the back part 10c through the first water-soluble tablet 21 with the first spring 22 built in, and the gas outlet of the auxiliary gas cylinder 40 is fixedly connected (including but not limited to bonding) to the inner wall of the cavity 12 corresponding to the front part 10a through the second water-soluble tablet 41 with the second spring 42 built in. However, it is understood that the fixing position and fixing method of the main gas cylinder 20 and the auxiliary gas cylinder 40 are not limited to this. For example, in Figure 6 In the embodiment shown, the outlet ends of all auxiliary gas cylinders 40a-40c can also be fixedly connected (including but not limited to bonding) to the back portion 10c of the cavity 12 (see Figure 1 ) on the inner wall, which are also not intended to limit the present invention.

[0035] In the present invention, the shape and size of the wearable lifesaving device 100 can be designed as required. Figure 1Taking the wearable lifesaving device 100 of the badge-like structure shown as an example, the maximum outer contour size of the shell 10 when not expanded can be designed to be 60mm (for example, the diameter of the outer contour of a circular badge), the caliber of the opening 11 is 10mm, and the outer diameter of the sealing member 30 is 12mm (for example, the maximum outer diameter of the protrusion 32 of the sealing member 30 can be 12mm, and the outer diameter of the connecting portion 31 can be 10mm). For example, the outer contour size of the side portion 10b of the shell 10 can also be designed to be 30mm. The maximum outer diameter of the main gas cylinder 20 can also be designed to be 15mm, and the caliber of the gas outlet can be 8mm; the maximum outer diameter of the auxiliary gas cylinder 40 can be 10mm, and the caliber of the gas outlet can be 6mm. However, it can be understood that the appearance and / or size of these components or parts are not limited to this, and can be adjusted and designed according to actual needs.
