[0002] The present invention relates to the technical field of diving devices, and particularly relates to an installation structure of a diving device and a diving device. Background Art

[0003] In the existing underwater wireless voice communication system, the underwater communication module for receiving and transmitting signals is fixed through an installation device. Such installation devices are generally suitable for installing the communication module on a diving mask or directly on the body of a diver. When installed on the diving mask, the communication module corresponds to one side or the top of the diver's head, which not only causes inconvenience in wearing and discomfort during wearing, but also easily causes signal occlusion and reduces the communication quality. When installed on the diver's body, it is generally fixed on the upper arm of the arm through a hook. However, for some other installation methods that do not require the communication module to be installed on the diving mask or the diver's body, such installation devices cannot meet the requirements. Summary of the Invention

[0015] In some embodiments, the second support has a limiting groove, and in the locked position, the connecting member is embedded in the limiting groove; or, the connecting member has a limiting groove, and in the locked position, the second support is embedded in the limiting groove.

[0016] In some embodiments, the second support includes:

[0017] An arc-shaped portion, which forms the second mounting position together with the first support in the locked position; and

[0018] A limiting portion, connected to the arc-shaped portion, protruding radially along the arc-shaped portion away from the center position of the second mounting position, and the limiting portion has a limiting groove;

[0019] In the locked position, the connecting member is embedded in the limiting groove, and the rotating arm abuts against the limiting portion.

Both ends of the connecting piece can rotate, and the rotating arm is pivotally connected to the connecting piece. When the rotating arm rotates, the rotating arm drives the connecting piece to rotate, forming a folding structure. This folding structure provides a gap for the second support to be embedded between the rotating arm and the first support, effectively ensuring the locking position of the second support and improving the reliability of the connection between the second support and the first support. In the embodiment of the present invention, the installation of the component at the second installation position can be realized by moving the second support and the rotating arm, without the need to rely on other disassembly and assembly tools, and the disassembly and assembly are convenient and fast.

Detailed implementation manners

[0059] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art fall within the protection scope of the present invention.

[0060] An embodiment of the present invention provides a diving device, which includes an air cylinder 400, an air pipe 410, a voice cable 700, a communication module 300, a headset 600, and a microphone module 190. The air pipe 410 is communicated with the air cylinder 400; the voice cable 700 is fixed on the air pipe 410; the communication module 300 is installed on the air cylinder 400 and is electrically connected to the voice cable 700. The communication module 300 is used for receiving a first wireless signal; the headset 600 is electrically connected to the voice cable 700 and is used for playing a first audio signal generated based on the first wireless signal; the microphone module 190 is electrically connected to the voice cable 700, and the microphone module 190 is used for collecting a second audio signal; the communication module 300 is further used for sending a second wireless signal generated based on the second audio signal.

[0061] In practical applications, the diving device further includes an above-water communication component (also known as a deck box) at least partially located above the water. The above-water communication module 300 can be installed on a ship and is used for establishing a communication connection with the communication module 300 located underwater. The above-water communication component, the communication module 300, the voice cable 700, the headset 600, the microphone module 190, etc. together form the communication system of the diving device. The communication module 300 has the function of receiving and sending wireless signals. By using the communication module 300, not only can the information interaction with the above-water communication component be realized, but also the information interaction with other divers 800 in the water can be realized. Taking the communication between two divers 800 as an example, after the communication module 300 of the diving device equipped by one diver 800 receives the first wireless signal, it converts the first wireless signal into a first electrical signal, and then the headset 600 converts the first electrical signal into a first audio signal. The microphone module 190 converts the collected second audio signal into a second electrical signal, and the communication module 300 converts the second electrical signal into a second wireless signal and sends it to another diver 800 to realize the information communication underwater. Both the first electrical signal and the second electrical signal are transmitted through the voice cable 700.

[0062] The wireless signal includes but is not limited to ultrasonic signals, optical signals, magnetic signals, etc.

[0063] The air cylinder 400 has a cavity for containing air or oxygen. The air or oxygen in the air cylinder 400 is transmitted to the mouth of the diver 800 through the air pipe 410 to realize the underwater breathing of the diver 800. As Figure 2 and Figure 4 shown, the installation structure can be fixed near the bottle mouth of the air cylinder 400 through the second installation position 150.

[0064] Generally, as Figure 1 and Figure 2As shown, the gas cylinder 400 is located on the back of the diver 800, which is a part of the body that is difficult to cover. By installing the communication module 300 on the gas cylinder 400, it is not only more convenient to install the communication module 300, but also reduces or even avoids the shielding of the communication module signal, improving the communication quality. Moreover, the communication module 300 does not need to be in contact with the body, reducing the movement restriction on the diver 800 and providing comfortable wearing.

[0065] When the communication module 300 is installed on the head or arm, the voice cable 700 exists as an independent cable, increasing the number and length of the exposed cables in the diving device. In the embodiment of the present invention, as Figure 1 and Figure 2 shown, by fixing the voice cable 700 on the air pipe 410, the voice cable 700 and the air pipe 410 can form an integral body, reducing the number and length of the exposed cables and effectively reducing the safety hazard.

[0066] Without limitation, the voice cable 700 is connected to the air pipe 410 by snap connection or bonding connection. The voice cable 700 can be detached from the air pipe as needed. For example: during use, as Figure 2 shown, the voice cable 700 is connected to the air pipe 410 by using the buckle 760 to fix the voice cable 700 to the air pipe 410. After use, when storing the diving device, the buckle 760 can be removed to separate the voice cable 700 from the air pipe 410, facilitating storage.

[0067] In some embodiments, the diving device further includes a charger, which is electrically connected to the communication module 300 and is at least used to supply power to the communication module 300.

[0068] In some other alternative embodiments, the voice cable 700 includes a main cable 710, a first cable 730, and a second cable 720. The main cable 710 is electrically connected to the communication module 300; both ends of the first cable 730 are electrically connected to the main cable 710 and the earphone 600 respectively; both ends of the second cable 720 are electrically connected to the main cable 710 and the microphone module 190 respectively; the main cable 710 is fixed on the air pipe 410, or, the main cable 710 and the second cable 720 are fixed on the air pipe 410 simultaneously.

[0069] As Figure 3 shown, the first cable 730 and the second cable 720 are electrically connected to one end of the main cable 710 away from the communication module 300 respectively. The voice cable 700 is in a substantially Y shape.

[0070] In practical applications, since the communication module 300 is installed on the gas cylinder 400, the setting directions of the main cable 710 and the second cable 720 are substantially the same as the setting direction of the air pipe 410, and both lead from the gas cylinder 400 to the mouth of the diver 800. Therefore, fixing the main cable 710 and the second cable 720 to the air pipe 410 respectively further increases the contact length between the voice cable 700 and the air pipe 410 compared with only fixing the main cable 710 to the air pipe 410, and further reduces the number and length of the exposed cables. Moreover, connecting the voice cable 700 to the air pipe 410 can utilize the air pipe 410 to reserve a moving length for the head movement range, reducing the limitation on the head movement range.

[0071] For the first cable 730, the first cable 730 is connected to the earphone 600, and the earphone 600 corresponds to the ear part of the head and is far from the mouth. Not fixing the first cable 730 to the air pipe 410 is beneficial to the convenient use of the earphone 600 and reduces the limitation of the first cable 730 on the head movement range.

[0072] In some embodiments, as Figure 3 shown, the first cable 730 includes a helical section 731 and a straight section 732. The two ends of the helical section 731 are electrically connected to the main cable 710 and the straight section 732 respectively, and the straight section 732 is connected to the earphone 600. The helical section 731 has elasticity and is wound in a helical manner, presenting a substantially helical shape. When subjected to an external tensile force, the helical section 731 can be stretched into a straight shape, and the length of the helical section 731 changes from L1 to L2, where L2 is greater than L1, increasing the length of the first cable 730. When the external force is removed, using the elastic restoring force of the helical section 731, the helical section 731 returns to the helical shape, and the length of the helical section 731 returns from L2 to L1. The first cable 730 with this structure can meet the needs of different divers 800.

[0073] Without limitation, the number of the straight sections 732 is two, and the two straight sections 732 are substantially in a Y shape with the helical section 731. In some embodiments, the diving device further includes a Y-shaped connection package 740 and a floating plug 750. The main cable 710 is connected to the helical section 731 of the first cable 730 and the second cable 720 respectively through the Y-shaped connection package 740; the helical section 731 is also connected to the two straight sections 732 respectively through the Y-shaped connection package 740, and the second cable 720 can be connected to the microphone module 190 through the floating plug 750.

[0074] In some other alternative embodiments, the diving device further includes: a mounting structure 900, the communication module 300 is mounted on the gas cylinder 400 through the mounting structure 900, and the mounting structure 900 includes: a base 100 and a bracket 200 fixed on the base 100. The bracket 200 includes a first mounting position for mounting the communication module 300. The base 100 includes a first support 110, a connecting member 140, a rotating arm 130, and a second support 120. Among them, the first support 110 is connected to the bracket 200; the connecting member 140 is pivotally connected to the first support 110; the rotating arm 130 is pivotally connected to the connecting member 140; the second support 120 has at least a locked position and an unlocked position relative to the first support 110. In the locked position, the second support 120 and the first support 110 together form a second mounting position 150 for mounting the gas cylinder 400. The second support 120 is located between the rotating arm 130 and the first support 110, and the rotating arm 130 abuts against the second support 120 to restrict the separation of the second support 120 from the first support 110. In the unlocked position, the rotating arm 130 is separated from the second support 120, and at least part of the second support 120 can be separated from the first support 110. The communication module 300 is mounted on the first mounting position; the gas cylinder 400 is mounted on the second mounting position 150.

[0075] As Figure 1 and Figure 2 shown, by using the mounting structure 900, it is possible to more conveniently mount the communication module 300 on the gas cylinder 400. It can be understood that the communication module 300 can also be mounted on the gas cylinder 400 through other structures such as clamps, buckles, or tapes.

[0076] As Figures 4 to 7 shown, the connecting member 140 is located between the rotating arm 130 and the first support 110, providing a gap 170 for the second support 120 to be embedded between the rotating arm 130 and the first support 110, effectively ensuring the locking effect on the second support 120. Both ends of the connecting member 140 can rotate, and the rotating arm 130 is pivotally connected to the connecting member 140. When the rotating arm 130 rotates, the rotating arm 130 drives the connecting member 140 to rotate, and the rotating arm 130 and the connecting member 140 form a folding structure. This folding structure not only facilitates the locking or unlocking of the second support 120, but also can effectively maintain the locked position of the second support 120, ensuring the reliability of the connection between the second support 120 and the first support 110.

[0077] In practical applications, the communication module 300 can be first mounted on the first mounting position, and then the mounting structure 900 can be fixed on the gas cylinder 400. During this process, when mounting with the gas cylinder 400, along the first direction (the first direction can beFigure 6 Rotate the rotating arm 130 in the clockwise direction (as shown), the rotating arm 130 drives the connecting member 140 to rotate, increasing the gap 170 between the rotating arm 130 and the first support 110, moving the second support 120 into the gap 170 between the rotating arm 130 and the first support 110, and then rotating the rotating arm 130 in the second direction opposite to the first direction (the second direction can be Figure 6 the counterclockwise direction as shown), so that the rotating arm 130 abuts against the second support 120, clamping the second support 120 between the rotating arm 130 and the first support 110 to lock the second support 120 and complete the installation process. When disassembling, rotate the rotating arm 130 in the first direction again to increase the gap 170 between the rotating arm 130 and the first support 110, so as to facilitate the separation of the second support 120 from the first support 110.

[0078] In the embodiment of the present invention, the installation of the component at the second installation position 150 can be achieved by moving the second support 120 and the rotating arm 130, without the need for other disassembly and assembly tools, and the disassembly and assembly are convenient and fast.

[0079] Without limitation, the materials of the bracket 200 and the base 100 can both be metal or plastic.

[0080] Compared with installing the communication module 300 on the face mask or the body, in this example, the communication module 300 is installed on the gas cylinder 400, which is simple to wear, reduces the limitation of movement after wearing the communication module 300, and improves the comfort of wearing the communication module 300. Moreover, the gas cylinder 400 is located on the back of the diver, which is a part that is difficult to be blocked by the diver's limb movement. By installing the communication module 300 on the gas cylinder 400, it is not only more convenient to install the communication module 300, but also reduces or even avoids the occlusion of the communication module signal, improving the communication quality.

[0081] In the locked position, the installation structure 900 can fix the communication module 300 and the gas cylinder 400 through the first installation position and the second installation position 150. In the unlocked position, the second installation position 150 cannot be formed. At this time, the installation structure 900 cannot perform the installation and fixing function, and the installation structure 900 can be disassembled using the unlocked position. After disassembling the installation structure 900, the communication module 300 is also separated from the gas cylinder 400 at the same time.

[0082] In the locked position, the gas cylinder 400 is located in the second installation position 150, and the first support 110 and the second support 120 jointly abut against the gas cylinder 400 to fix the installation structure 900 on the gas cylinder 400.

[0083] Figure 4 and Figure 7 Exemplarily shows a schematic structural diagram of the installation structure in the locked position. Figure 6The structural schematic diagram of the mounting structure when in the unlocked position is exemplarily shown. Figure 5 Located between the locked position and the unlocked position, at this time, the rotating arm 130 has an interference effect in the direction of the separation of the second support 120 from the first support 110. Although the second support 120 cannot be separated from the first support 110, at this time, the fixing of the first support 110 and the second support 120 to the gas cylinder 400 is lower than that when in the locked position, where the fixing of the first support 110 and the second support 120 to the gas cylinder 400 is concerned.

[0084] Without limitation, the first mounting position can be a plane, a hole or a groove, and fasteners such as bolts can be used to fix the communication module 300 on the first mounting position.

[0085] Without limitation, as Figure 4 and Figure 7 shown, the second mounting position 150 is a hole, the first support 110 includes a first arc surface 111, and the second support 120 includes a second arc surface 1211. When in the locked position, the first arc surface 111 and the second arc surface 1211 together form the hole wall of the second mounting position 150.

[0086] Combined with Figure 2 and Figure 4 shown, when the second mounting position 150 is connected to the gas cylinder 400, in order to adapt to the gas cylinder 400, the second mounting position 150 is a generally circular hole. It can be understood that the shape of the second mounting position 150 can also be any shape such as a square, an ellipse or a hexagon.

[0087] As Figure 4 and Figure 7 shown, when in the locked position, the position where the rotating arm 130 abuts against the second support 120 is adjacent to the connection position of the rotating arm 130 and the connecting member 140. Thus, even if a relatively large external force in the direction away from the center position of the second mounting position 150 acts on the second support 120, the second support 120 cannot easily push the rotating arm 130 to rotate, further ensuring the reliability of the connection between the second support 120 and the first support 110 when in the locked position.

[0088] In some embodiments, as Figures 4 to 7 shown, the mounting structure 900 further includes: a first rotating shaft 141 and a second rotating shaft 142 respectively installed at both ends of the connecting member 140. The first support 110 is pivotally connected to the connecting member 140 through the first rotating shaft 141, and the rotating arm 130 is pivotally connected to the connecting member 140 through the second rotating shaft 142.

[0089] In some other alternative embodiments, the first end of the second support 120 is pivotally connected to the first support 110; in the locked position, the second end of the second support 120 is located between the first support 110 and the rotating arm 130; wherein, the second end is the opposite end of the first end.

[0090] As Figures 4 to 7 shown, the rotating arm 130 fixes the second end of the second support 120 between the rotating arm 130 and the first support 110 by abutting against the second end of the second support 120, thereby locking the second support 120.

[0091] In practical applications, by rotating the second support 120 in different directions, the second end of the second support 120 can be inserted between the rotating arm 130 and the first support 110, or the second end of the second support 120 can be separated from the first support 110.

[0092] Without limitation, the first end of the second support 120 can be pivotally connected to the first support 110 through the third rotating shaft 143.

[0093] The first end of the second support 120 is pivotally connected to the first support 110. Even in the unlocked position, the second support 120 will not be completely separated from the first support 110, improving the integrity of the installation structure 900.

[0094] In some embodiments, the first end and the second end of the second support 120 can be separated from the first support 110 respectively. At this time, in the unlocked position, the second support 120 can be completely separated from the first support 110. The fixing manner of the first end of the second support 120 to the first support 110 can be the same as that of the second end of the second support 120 to the first support 110. That is, compared with the installation structure 900 in Figures 4 to 7 when in the locked position, the first end of the second support 120 is also locked between the rotating arm 130 and the first support 110.

[0095] In some other alternative embodiments, the second support 120 has a limiting groove 1221, and in the locked position, the connecting member 140 is embedded in the limiting groove 1221; or, the connecting member 140 has a limiting groove 1221, and in the locked position, the second support 120 is embedded in the limiting groove 1221.

[0096] To Figures 4 to 7Taking the second support 120 shown as an example with a limiting groove 1221. After the connecting member 140 is embedded in the limiting groove 1221, the limiting groove 1221 can at least limit the movement of the connecting member 140 in a direction perpendicular to the base 100. And the abutment of the rotating arm 130 against the second support 120 is more conducive to restricting the movement of the second support 120 in a direction parallel to the base 100. Therefore, setting the limiting groove 1221 can further improve the reliability of the connection between the second support 120 and the first support 110 when in the locked position.

[0097] In some other alternative embodiments, the second support 120 includes an arc portion 121 and a limiting portion 122. When in the locked position, the arc portion 121 and the first support 110 jointly form the second mounting position 150; the limiting portion 122 is connected to the arc portion 121 and protrudes in a direction away from the central position of the second mounting position 150 along the radial direction of the arc portion 121. The limiting portion 122 has a limiting groove 1221; when in the locked position, the connecting member 140 is embedded in the limiting groove 1221, and the rotating arm 130 abuts against the limiting portion 122.

[0098] Limiting portions 122 can be respectively provided at the first end and the second end of the second support 120, or, as Figures 4 to 7 shown, a limiting portion 122 can be provided only at the second end of the second support 120, and the first end is pivotally connected to the first support 110.

[0099] The second arc surface 1211 is located on the surface of the arc portion 121 facing the first support 110. The second support 120 fixes the gas cylinder 400 through the second arc surface 1211.

[0100] In some other alternative embodiments, when in the locked position, the rotating arm 130 is arranged along the circumferential direction of the arc portion 121.

[0101] As Figures 4 to 7 shown, the shape of the rotating arm 130 is generally arc-shaped. The shape of the rotating arm 130 can be generally the same as the shape of the arc portion 121.

[0102] The rotating arm 130 arranged along the circumferential direction of the arc portion 121 is less likely to rotate, further improving the locking effect on the second support 120 when in the locked position.

[0103] It can be understood that the longer the length of the rotating arm 130 arranged along the circumferential direction of the arc portion 121, the more conducive it is to locking the second support 120. In some embodiments, the length of the rotating arm 130 arranged along the circumferential direction of the arc portion 121 is about 1 / 2 to 1 of the length of the arc portion 121.

[0104] In some other alternative embodiments, the mounting structure 900 further includes: a flexible member 160 located within the second mounting position 150.

[0105] The flexible member 160 is used to strengthen the connection strength between the second mounting position 150 and the gas cylinder 400.

[0106] Without limitation, the flexible member 160 can be rubber or fiber fabric, etc. Rubber includes but is not limited to silica gel.

[0107] In some other alternative embodiments, the bracket 200 has a first through hole 240; the first support 110 has a second through hole 112; the mounting structure 900 further includes a rotating shaft 210 and a limiting protrusion 220. The rotating shaft 210 passes through the first through hole 240 and the second through hole 112 at the same time; the limiting protrusion 220 is located on the rotating shaft 210; the bracket 200 has at least an unfolded position and a folded position relative to the base 100; in the unfolded position, the limiting protrusion 220 is located within the first through hole 240 and the second through hole 112 at the same time, and the limiting protrusion 220 restricts the bracket 200 from rotating relative to the first support 110 along the axis of the rotating shaft 210; in the folded position, the limiting protrusion 220 is separated from the second through hole 112, the limiting protrusion 220 is located within the first through hole 240 and abuts against the first support 110, and the bracket 200 can rotate relative to the first support 110 along the axis of the rotating shaft 210.

[0108] In the embodiments of the present invention, the unfolded position can be the working position during diving operations. The folded position is the non - working position. Relatively speaking, in the folded position, the mounting structure 900 occupies less space, which is convenient for the storage of the mounting structure 900.

[0109] Without limitation, the rotating shaft 210 can be a folding bolt.

[0110] The limiting protrusion 220 can maintain the unfolded position of the bracket 200 and prevent the bracket 200 from rotating relative to the base 100 undesirably.

[0111] Without limitation, when in the unfolded position, the bracket 200 is perpendicular to the base 100; when in the folded position, the bracket 200 is parallel to the base 100.

[0112] Figure 4 Exemplarily, a schematic structural diagram of the mounting structure in the unfolded position is shown. Figure 7 Exemplarily, a schematic structural diagram of the mounting structure in the folded position is shown. Figure 6 Exemplarily, a schematic structural diagram of the mounting structure when it is between the unfolded position and the folded position is shown.

[0113] AsFigure 5 As shown, the limiting protrusion 220 is always located within the first through hole 240. Due to the anti-rotation effect of the limiting protrusion 220, the rotating shaft 210 cannot rotate around the axis of the first through hole 240 within the first through hole 240, but can move axially within the first through hole 240. By moving the rotating shaft 210, the limiting protrusion 220 can be moved into the second through hole 112 or outside the second through hole 112. When the limiting protrusion 220 is located within the second through hole 112, the limiting protrusion 220 prevents the first support 110 from rotating relative to the rotating shaft 210; when the limiting protrusion 220 is located outside the second through hole 112, the limiting protrusion 220 cannot prevent the first support 110 from rotating relative to the rotating shaft 210, and the first support 110 and the bracket 200 can rotate relative to each other, thereby realizing the transition from the unfolded position to the folded position.

[0114] In some other alternative embodiments, the mounting structure further includes: an elastic member 230, with two ends respectively connected to the bracket 200 and the rotating shaft 210; in the folded position, the elastic member 230 is in an elastically deformed state storing elastic restoring force; between the folded position and the unfolded position, the elastic member 230 releases the elastic restoring force.

[0115] In some embodiments, in the folded position, the limiting protrusion 220 abuts against the first support 110. When transitioning from the folded position to the unfolded position, when the bracket 200 rotates in place or the first support 110 rotates in place, the second through hole 112 aligns with the limiting protrusion 220 again, and under the action of the elastic restoring force of the elastic member 230, the limiting protrusion 220 automatically enters the second through hole 112.

[0116] Therefore, the elastic member 230 can automatically realize the connection between the limiting protrusion 220 and the second through hole 112, facilitating operation.

[0117] Without limitation, the elastic member 230 can be a spring or a spring sheet. Springs include but are not limited to tension springs.

[0118] In some embodiments, the diving device includes the mounting structure, the communication module 300, and the gas cylinder 400 described in any of the above embodiments. The communication module 300 is mounted on the first mounting position; the gas cylinder 400 is mounted on the second mounting position 150.

[0119] The diving device further includes a breathing mouthpiece 500, and the breathing mouthpiece 500 includes: a housing 510, a fixing bracket 520, a mouthpiece 521, and a mouth sleeve 530. The housing 510 has an air inlet 511 and an air outlet 512. The air inlet 511 communicates with the air outlet 512. The air pipe 410 communicates with the air inlet 511. The microphone module 190 is located inside the housing 510. The fixing bracket 520 is installed inside the housing 510, and the microphone module 190 is fixed on the fixing bracket 520. The mouthpiece 521 is fixed on the fixing bracket 520, passes through the air outlet 512, and is at least exposed outside the housing 510. The mouth sleeve 530 is sleeved outside the mouthpiece 521.

[0120] During actual use, the air outlet 512 faces the diver's oral cavity. As Figure 8 and Figure 9 shown, the housing 510 is a hollow member, and the housing 510 further has a gas passage located between the air outlet 512 and the air inlet 511. The air inlet 511 is used to communicate with the gas cylinder, so that the gas provided by the gas cylinder 400 enters the gas passage through the air inlet 511 and then flows from the air outlet 512 to the diver 800's oral cavity, realizing the diver 800's inhalation underwater.

[0121] Generally, the rigidity of the fixing bracket 520 is greater than that of the housing 510. The fixing bracket 520 has a supporting effect on the housing 510. At the same time, the fixing bracket 520 is at least used to fix the mouthpiece 521.

[0122] In some embodiments, the cross-sectional area of the housing 510 gradually decreases from the air inlet 511 to the air outlet 512 direction. As Figure 1 、 Figure 2 and Figure 8 and Figure 9 shown, the air outlet 512 part of the housing 510 that fits with the diver 800's mouth is designed to be streamlined. The outer surface of the housing 510 is generally conical, which is roughly the same as the shape of a duck's bill. This shape of the housing 510 is beneficial to reducing the resistance when the diver 800 swims, and at the same time, it is more tightly attached to the face under the action of water pressure.

[0123] Without limitation, the housing 510 can be made of silicone material. The silicone material is relatively soft and has good elasticity, which is more convenient for the assembly of the housing 510 and the fixing bracket 520.

[0124] The mouthpiece 521 and the fixing bracket 520 can be a split structure. At this time, the mouthpiece 521 can be fixed on the fixing bracket 520 by welding, bonding, clamping, or threaded connection, etc. Or, the mouthpiece 521 and the fixing bracket 520 are an integral structure, and the fixing bracket 520 and the mouthpiece 521 can be made by an integral molding method such as injection molding or machining.

[0125] In practical applications, the mouthpiece 521 and the mouth cover 530 simultaneously extend into the mouth of the diver 800. To ensure that the breathing mouth mask 500 does not easily separate from the face of the diver 800, the mouthpiece 521 needs to have a certain supporting effect on the mouth of the diver 800, while the mouth cover 530 only needs to isolate the mouthpiece 521 and the mouth. Therefore, relatively speaking, there is no special requirement for the rigidity of the mouth cover 530. The mouth cover 530 can be made of flexible and / or elastic waterproof materials, such as silicone. The mouth cover 530 made of this material is convenient to carry and occupies little space when stored.

[0126] Without limitation, there are at least two mouthpieces 521, and the number of mouth covers 530 is the same as the number of mouthpieces 521. Each mouthpiece 521 is sleeved with a mouth cover 530.

[0127] In the embodiment of the present application, by sleeving the mouth cover 530 on the mouthpiece 521, the mouth of the diver 800 of the breathing mouth mask 500 contacts the mouth cover 530 and does not directly contact the mouthpiece 521. When different divers 800 share the same breathing mouth mask 500 or the mouth cover 530 is contaminated, the mouth cover 530 can be detached from the mouthpiece 521 and replaced, improving the hygiene problem during the use of the breathing mouth mask 500. Moreover, by replacing the mouth cover 530 instead of the entire mouthpiece 521, it is also beneficial to save costs.

[0128] In other alternative embodiments, the mouth cover 530 has a receiving cavity 532 and an opening 531 communicating with the receiving cavity 532. The mouthpiece 521 passes through the opening 531 and is at least partially located in the receiving cavity 532.

[0129] The mouth cover 530 is a hollow member. As Figure 10 and Figure 11 shown, one end of the mouth cover 530 is open 531, which facilitates the installation of the mouth cover 530 on the mouthpiece 521. The other end of the mouth cover 530 is closed, ensuring the coverage of the mouthpiece 521 by the mouth cover 530 and further avoiding the contact between the mouthpiece 521 and the mouth.

[0130] In other alternative embodiments, the mouth cover 530 further has a limiting hole 533 communicating with the receiving cavity 532. The limiting hole 533 and the opening 531 are located on different surfaces of the mouth cover 530 respectively; the mouthpiece 521 includes a supporting portion 5211 and a first limiting portion 5212. The supporting portion 5211 is fixed on the fixing frame 520 and is located in the receiving cavity 532; the first limiting portion 5212 is connected to the supporting portion 5211 and can pass through the limiting hole 533 to limit the separation of the mouth cover 530 from the supporting portion 5211.

[0131] The cooperation between the limiting hole 533 and the first limiting portion 5212 further strengthens the connection between the mouthpiece sleeve 530 and the mouthpiece 521, restricting the mouthpiece sleeve 530 from detaching from the mouthpiece 521.

[0132] Without limitation, for example Figure 10 and Figure 12 as shown, the first limiting portion 5212 can be a cylindrical protrusion or a hook approximately in an L shape.

[0133] In some embodiments, the distance between the first limiting portion 5212 and the end of the mouthpiece sleeve 530 close to the fixing bracket 520 is less than the distance between the first limiting portion 5212 and the other end of the mouthpiece sleeve 530 far from the fixing bracket 520. For example Figure 10 as shown, in practical applications, when the mouthpiece sleeve 530 extends into the oral cavity and the first limiting portion 5212 is arranged at the free end far from the mouthpiece 521, the contact between the first limiting portion 5212 exposed outside the mouthpiece sleeve 530 and the oral cavity can be reduced or even avoided, further ensuring the hygiene condition of the breathing mouth mask 500.

[0134] In other alternative embodiments, the mouthpiece 521 further includes a second limiting portion 5213, the second limiting portion 5213 is located at the end of the supporting portion 5211 far from the fixing bracket 520, and the first limiting portion 5212 is located between the second limiting portion 5213 and the fixing bracket 520; the cross-sectional area of the second limiting portion 5213 is larger than the cross-sectional area of the supporting portion 5211, restricting the mouthpiece 521 from detaching from the oral cavity of the diver 800.

[0135] In practical applications, since the cross-sectional area of the second limiting portion 5213 is larger than the cross-sectional area of the supporting portion 5211, the second limiting portion 5213 is less likely to detach from the oral cavity, further strengthening the connection between the mouthpiece 521 and the oral cavity, and further ensuring the fitting degree between the breathing mouth mask 500 and the face of the diver 800.

[0136] In other alternative embodiments, the mouthpiece sleeve 530 further has an avoidance hole 534, the avoidance hole 534 communicates with the accommodation cavity 532 and is distributed at intervals with the opening 531; the avoidance hole 534 is distributed along the setting direction of the mouthpiece 521.

[0137] In practical applications, after the avoidance hole 534 is provided, the avoidance hole 534 can be expanded, and it is easier to detach the mouthpiece sleeve 530 from the mouthpiece 521 or install the mouthpiece sleeve 530 by means of the avoidance hole 534.

[0138] For example Figure 10 as shown, the setting direction of the avoidance hole 534 is substantially the same as the setting direction of the supporting portion 5211 of the mouthpiece 521. Without limitation, the avoidance hole 534 is a long strip hole.

[0139] In some embodiments, the mouthpiece 530 has substantially the same shape as the bite piece 521. As Figures 10 to 12 shown, the mouthpiece 530 and the bite piece 521 with substantially the same shape can fit better.

[0140] As Figure 10 、 Figure 12 shown, the bite piece 521 is a toothed member. The toothed member occupies less space in the oral cavity and can facilitate the diver 800 to speak on the premise of facilitating biting. The support portion 5211 and the second limiting portion 5213 of the bite piece 521 are disposed substantially perpendicular to each other. As Figure 11 shown, the mouthpiece 530 is composed of a horizontal section 535 and a vertical section 536. A relief elongated hole (i.e., the avoidance hole 534) is formed in the middle of the vertical section 536 and extends to the horizontal section 535. The horizontal section 535 is sleeved on the support portion 5211, and the vertical section 536 is sleeved on the second limiting portion 5213. The setting of the relief elongated hole facilitates the disassembly and assembly of the mouthpiece 530. To prevent the mouthpiece 530 from slipping off during use, an L-shaped hook extends outward from the outer side wall of the support portion 5211, and a square hole is formed in the side wall of the horizontal section 535 of the mouthpiece 530, and the square hole is adapted to the L-shaped hook.

[0141] In other alternative embodiments, the breathing mouth mask 500 further includes a switch member 580, and the switch member 580 is electrically connected to the microphone module 190; the switch member 580 is used to turn on or off the call function of the microphone module 190.

[0142] The microphone module 190 is used to collect the second audio signal generated by the speech of the diver 800.

[0143] The switch member 580 can be a button. When the diver 800 needs to communicate, the button can be pressed, and the microphone module 190 works, and the received audio is transmitted to the underwater communication device through the voice cable 700. When the diving operation is over, the mouthpiece 530 is removed and the bite piece 521 is cleaned. A brand-new mouthpiece 530 can be replaced for the next use to ensure the cleanliness and hygiene when used by different people.

[0144] By electrically connecting the switch member 580 to the microphone module 190, the call function of the microphone module 190 can be controlled, and the timeliness of communication can be improved.

[0145] Without limitation, the voice cable 700 can be a waterproof cable, also known as a watertight cable.

[0146] In other alternative embodiments, the breathing mouthpiece 500 further includes a first fixing base 572 and a second fixing base 571. The first fixing base 572 is mounted on the fixing frame 520; the second fixing base 571 covers the first fixing base 572 and jointly forms a sealed cavity with the first fixing base 572. The sealed cavity houses the microphone module 190, at least part of the voice cable 700, and at least part of the switch member 580.

[0147] As Figure 13 shown, the microphone module 190, a part of the voice cable 700 connected to the microphone module 190, and the switch member 580 are all connected to the fixing frame 520 through the first fixing base 572. By integrating the microphone module 190, a part of the voice cable 700, and the switch member 580 in a sealed cavity, it is convenient for sealed installation, effectively preventing water outside the sealed cavity from entering the sealed cavity and contacting the microphone module 190, a part of the voice cable 700, and the switch member 580 during diving, and effectively protecting the communication function of the breathing mouthpiece 500.

[0148] Without limitation, a sealing ring can be provided between the first fixing base 572 and the second fixing base 571 to form a sealed cavity after the first fixing base 572 and the second fixing base 571 are covered.

[0149] In some embodiments, an installation groove 573 is formed on the first fixing base 572. The installation groove 573 is part of the sealed cavity. The microphone module 190, a part of the voice cable 700, and the switch member 580 are all installed in the installation groove 573, and sealing members are provided between the assembly gaps of the microphone module 190, a part of the voice cable 700, and the switch member 580 and the first fixing base 572. The sealing member includes but is not limited to silicone. The sealing member not only further ensures the sealing performance of each assembly gap, but also helps to strengthen the connection strength between the microphone assembly and the first fixing base 572, the connection efficiency between the connection effect and the first fixing base 572, and the connection strength between the switch member 580 and the first fixing base 572.

[0150] In other alternative embodiments, the breathing mouthpiece 500 further includes ear hooks 560 and a fixing strap. The ear hooks 560 are fixed on the housing 510 and form an installation hole 561 with the housing 510. Both ends of the fixing strap are fixed on the fixing frame 520 through the installation hole 561.

[0151] The installation hole 561 is used to realize the connection between the fixing strap and the housing 510. The fixing strap is used to fix the breathing mouthpiece 500 on the head of the diver 800, improving the tightness of the fit between the breathing mouthpiece 500 and the face and facilitating the wearing of the breathing mouthpiece 500.

[0152] The number of the installation holes 561 is at least two, Figure 8 andFigure 9 Exemplarily, a housing 510 having two mounting holes 561 is shown.

[0153] In practical applications, the lugs 560 and the housing 510 together form the mounting holes 561, rather than forming the mounting holes 561 by opening on the housing 510, which is beneficial to ensure the sealing performance of the housing 510. The mounting holes 561 are located on the housing 510 at positions adjacent to the ears of the diver 800. When worn, the head of the diver 800 is located between the fixing strap and the housing 510. The two ends of the fixing strap respectively pass through the mounting holes 561 at two different positions. After the fixing strap is fixed to the housing 510, the diver 800 can adjust the fixing strength of the fixing strap by changing the length of the fixing strap.

[0154] In some embodiments, the fixing strap is of an integral structure, and the two ends of the fixing strap respectively pass through the mounting holes 561 at different positions; or, the fixing strap is of a split structure, that is, the fixing strap includes a first fixing strap and a second fixing strap. While the first fixing strap and the second fixing strap are connected by a joint member, the first fixing strap and the second fixing strap are also connected to the mounting holes 561 at different positions. When disassembling the breathing mask from the head of the diver 800, the elasticity of the fixing strap can be utilized to increase the distance between the fixing strap and the housing 510, or the locking of the first fixing strap and the second fixing strap by the connector can be released to achieve disassembly. The connector can be a snap-type quick-release connector.

[0155] In other alternative embodiments, the breathing mouthpiece 500 further includes: a sealing strip 550, fixed on the fixing frame 520 and distributed along the circumferential side of the air outlet 512.

[0156] As Figure 8 and Figure 9 shown, the sealing strip 550 is used to seal the gap between the housing 510 and the face of the diver 800, to prevent water from entering the interior of the housing 510 through the gap between the housing 510 and the face of the diver 800.

[0157] In other alternative embodiments, the earphone includes a base 10, a cover 20, a magnetic core 30, and a driving circuit (not shown). The cover 20 covers the base 10, and the cover 20 and the base 10 together form a sealing cavity 11; the magnetic core 30 is located in the sealing cavity 11; the driving circuit is electrically connected to the magnetic core and the voice cable respectively, and drives the magnetic core to vibrate by changing the electrical signal passing through the magnetic core, and drives the cover to resonate to generate the first audio signal.

[0158] The driving circuit drives the magnetic core 30 to vibrate, and the magnetic core 30 drives the cover 20 to resonate and generate sound. Compared with piezoelectric ceramic earphones, the sound quality output by the earphone in the embodiment of the present application is less affected by the vibration source magnetic core 30, but is related to the cover 20. This way of resonating and generating sound can effectively improve the problem of sharp sound.

[0159] Moreover, compared with the driving circuit of piezoelectric ceramic earphones, the driving circuit of the earphone in the embodiment of the present application can be simpler and have lower cost.

[0160] By selecting covers 20 made of different materials, sounds with different sound qualities can be output, and sound qualities with good high-frequency, medium-frequency or low-frequency responses can be obtained. For example: when the material of the cover 20 is wood, a deep sound quality with good low frequency can be output. When the material of the cover 20 is beryllium copper alloy, a sound quality with more prominent high frequency can be obtained. When the material of the cover 20 is glass, a clear and ethereal sound quality can be obtained, and the sound frequency is between that of the cover 20 made of wood and beryllium copper alloy. It can be understood that the material of the red cover 20 in the embodiment of the present application is not limited to the above several, and can also be other materials such as plastic and cast iron.

[0161] In some embodiments, the magnetic core 30 includes: a magnetostrictive body and a coil wound around the magnetostrictive body. After passing an alternating current through the coil, an alternating magnetic field is generated. Under the action of the alternating magnetic field, the magnetostrictive body generates elongation and shortening changes, that is, generates vibration. The magnetostrictive body is generally a metal material. For example: the material of the magnetostrictive body includes but is not limited to metals such as iron, cobalt, nickel and their alloys.

[0162] Without limitation, the driving circuit can also be located in the sealed cavity 11. The driving circuit can realize the vibration of the magnetostrictive body by changing parameters of electrical signals such as the current intensity, current direction, and frequency of the alternating current passing through the coil.

[0163] By replacing the magnetic core 30 with different powers, or by controlling the circuit to change the current intensity passing through the magnetic core 30 and other methods, the loudness of the sound output by the earphone can be made different to meet the requirements of different scenarios. For example: the loudness of the output sound can be increased by increasing the power of the magnetic core 30; conversely, the loudness of the output sound can be decreased by decreasing the power of the magnetic core 30.

[0164] By selecting covers 20 and bases 10 with different thickness dimensions, the earphone can meet the requirements of different pressure resistance strengths. Generally, for the same material, the greater the thickness, the more pressure-resistant the earphone is, and the deeper the diving depth it can adapt to.

[0165] The sealed cavity 11 can prevent the liquid in the external environment where the earphone is located from entering, and has a protective effect on the magnetic core 30.

[0166] In the embodiments of the present application, the sealing cavity 11 jointly formed by the cover body 20 and the base 10 ensures the waterproof and pressure-resistant effects of the earphone when used underwater.

[0167] In some other alternative embodiments, the earphone further includes: a shock pad 60, located between the magnetic core 30 and the base 10.

[0168] As Figure 14 shown, the shock pad 60 can reduce the transmission of vibrations generated by the magnetic core 30 to the base 10, ensure that the vibrations are transmitted in the direction of the cover body 20, improve the directivity of sound transmission, and is beneficial to improving the privacy of the earphone.

[0169] The material of the shock pad 60 includes but is not limited to rubber or foam.

[0170] In practical applications, the shock pad 60 fills the gap between the magnetic core 30 and the base 10, and also has a fixing effect on the magnetic core 30, reducing or even avoiding the shaking of the magnetic core 30 in the sealing cavity 11.

[0171] In some other alternative embodiments, the cover body 20 and the base 10 are adhesively connected or welded at the joint.

[0172] By using the adhesive or welding method, not only can the cover body 20 be fixed on the base 10, but also the gap between the cover body 20 and the base 10 can be sealed, ensuring the tightness of the sealing cavity 11.

[0173] In some embodiments, the earphone further includes a sealing ring (not shown), which is located between the cover body 20 and the base 10 to seal the gap between the cover body 20 and the base 10. The sealing ring can further ensure the airtight and waterproof effect of the sealing cavity 11.

[0174] The adhesive includes but is not limited to epoxy resin glue or acrylate glue.

[0175] Without limitation, the welding can use ultra-high frequency welding technology.

[0176] In some other alternative embodiments, the magnetic core 30 is adhesively connected to the cover body 20.

[0177] Adhesively connecting the magnetic core 30 to the cover body 20 is beneficial to stabilizing the magnetic core 30 and also beneficial to the magnetic core 30 driving the cover body 20 to vibrate, further improving the sound generation effect.

[0178] The adhesive connection between the magnetic core 30 and the cover body 20 can be bonded with an adhesive or bonded with an adhesive tape.

[0179] In some other alternative embodiments, the earphone further comprises: a connector 50; the voice cable 700 passes through the base 10 and is electrically connected to the drive circuit; the connector 50 forms a liquid-tight structure at the position where the partial voice cable 700 passes through the base 10.

[0180] In practical applications, the partial voice cable 700 can be electrically connected to the communication module in the diving device. After the communication module converts the received information into an audio electrical signal, it is transmitted to the magnetic core 30 through the partial voice cable 700.

[0181] As Figures 14 to 17 shown, the partial voice cable 700 passes through the connector 50, and the partial voice cable 700 extends at least outside the sealing cavity 11 for electrically connecting to the communication module. The connector 50 is used to seal the gap formed when the partial voice cable 700 passes through the base 10 to ensure the sealing performance of the sealing cavity 11. In addition, the connector 50 is located at the connection between the partial voice cable 700 and the base 10, which has a supporting effect on the partial voice cable 700 and reduces the risk of bending damage to the partial voice cable 700 at the connection with the base 10.

[0182] In some other alternative embodiments, the connector 50 forms the liquid-tight structure by bonding or welding with the base 10.

[0183] The adhesive includes but is not limited to epoxy resin glue or acrylate glue.

[0184] Without limitation, the welding can use ultra-high frequency welding technology.

[0185] To further ensure the sealing effect, the earphone further comprises a sealing member (not shown). A sealing member is provided at the connection between the connector 50 and the base 10, and / or at the connection between the connector 50 and the voice cable 700. The sealing member can be an elastic rubber member.

[0186] In some other alternative embodiments, as Figures 15 to 17 shown, the earphone further comprises: a hanger 70. One end of the hanger 70 has a receiving groove 72, and the receiving groove 72 at least accommodates the base 10. The other two ends of the hanger 70 include hooks 71.

[0187] The hanger 70 has a fixed connection function, which facilitates the wearing of the earphone.

[0188] In some embodiments, the base 10 and the receiving groove 72 are in interference fit. The interference fit ensures the reliability of the connection between the base 10 and the hanger 70 and facilitates the disassembly of the hanger 70.

[0189] In some embodiments, as Figure 15 and Figure 16As shown, the cover body 20 is exposed outside the receiving groove 72. In practical applications, the cover body 20 faces the human ear, and sound is received through the cover body 20. The cover body 20 exposed outside the receiving groove 72 reduces the cover body 20 being covered by the hanger 70, ensuring the sound transmission effect.

[0190] The hanger 70 can be installed or not according to needs. When the diver is wearing a diving hood, the hanger 70 may not be needed, and the Figure 14 shown earphone can be directly inserted into the hood. When the diver is not wearing a diving hood, the hanger 70 is needed. The hanger 70 is installed on the diver's face mask by using the hook 71, and the fixation of the earphone can be achieved.

[0191] In some other alternative embodiments, the second end of the hanger 70 is bent to form the hook 71.

[0192] The hook 71 formed by bending has a simple structure and is convenient to connect.

[0193] In some other alternative embodiments, the wall of the receiving groove 72 formed by the hanger 70 has an avoidance opening 73.

[0194] As Figure 17 shown, the avoidance opening 73 is used to avoid the voice cable 700, so that the voice cable 700 does not need to be bent when passing through the hanger 70, which is beneficial to ensuring the service life of the voice cable 700.

[0195] In a specific example, as Figures 1 to 17 shown, the communication module 300 is installed on the gas cylinder 400 containing compressed air through the installation structure 900. Installing the communication module 300 on the gas cylinder 400 can prevent the communication module 300 from being blocked, improving the efficiency and quality of wireless signal transmission and reception. The voice cable 700 is buckled on the air pipe 410. The earphone 600 includes a hanger 70. When the diver 800 uses a diving hood, the earphone 600 can be directly inserted into the hood. When not using the diving hood, the earphone 600 is hung on the diving face mask through the hanger 70. The breathing mouthpiece 500 includes a silica gel hanging strap (also known as a fixing strap). When not using the breathing mouthpiece 500, the breathing mouthpiece 500 is suspended in front of the chest through the silica gel hanging strap. The breathing mouthpiece 500 includes a mechanical button (i.e., the switch member 580), and the mechanical button has a waterproof and pressure-resistant structure. Through different pressing methods of the mechanical button, the diver realizes information interaction with the underwater communication module 300. In this example, the diving device has the advantages of good communication performance, quick disassembly and assembly, reduced safety hazards, clear sound collection of the microphone module 190, and full audio of the earphone 600. Moreover, the communication module 300 of the embodiment of the present invention reduces the possibility of being blocked, and has good signal transmission quality; using a toothed mouthpiece for pronunciation and sound collection is clearer.

[0196] The features disclosed in several product embodiments provided by the present invention can be arbitrarily combined without conflict to obtain new product embodiments.

[0197] Other structures and operations of the products according to the embodiments of the present invention are understandable and easy to implement for those skilled in the art, and thus will not be described in detail.

[0198] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
