Description
Technical Field
[0001] This utility model relates to the field of diving equipment, specifically a mouthpiece diving mask. Background Technology
[0002] A mouthpiece diving mask is a type of protective equipment designed specifically for scuba diving. Its core feature is the separation of the mouth and nose. The mask only covers the diver's eyes and nose area, providing clear vision and a waterproof seal, while the mouth is completely exposed and used to bite the mouthpiece of an independent regulator. This design allows the diver to breathe compressed air directly from the cylinder through the regulator, and the exhaled exhaust gas is discharged through the exhaust valve on the side of the regulator.
[0003] While the mouthpiece design overcomes the dead space defect of full-face masks in current diving mask technology, it still has systemic bottlenecks. The instability of the secondary head under water flow impact can lead to seal failure. At the same time, the rigid connection between the mouthpiece and the secondary head restricts head movement, which can easily cause temporomandibular joint fatigue with long-term use. Furthermore, the fixed connection between the trachea and the secondary head requires replacement of the entire device during maintenance, which significantly increases the cost of use. In view of this, the inventors urgently need to design a mouthpiece diving mask that enhances the stability of the diving mask under water flow impact and allows for mouthpiece angle adjustment. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a mouthpiece diving mask to solve the technical problems of system instability and mouthpiece angle hardening of diving masks under water flow impact.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mouthpiece diving mask, comprising a mask body, a matching secondary head body disposed on the lower side of the mask body, a support plate disposed on one side of the secondary head body, the support plate being connected to the secondary head body via a support plate frame, a mouthpiece mounting bracket disposed at the breathing output end of the secondary head body, and a movable omnidirectional ball disposed at the middle position between the mouthpiece mounting bracket and the secondary head body.
[0006] By adopting the above technical solutions, the separate design of the mask body and the secondary head body enables independent maintenance of functional modules. The breathing unit can still be reused when the mask body is damaged, which significantly reduces the cost of use. The precision locking structure of the separate interface ensures water tightness and avoids irreversible damage to the body.
[0007] Furthermore, a goggle is provided on one side of the main body of the mask, a detachable mask strap is installed on one side of the goggle, and a nose shield is fixedly connected to the lower side of the goggle and extends into the inside of the main body of the mask.
[0008] By adopting the above technical solution, the integrated structure of the goggles and the mask body forms a seamless optical curved surface, eliminating the assembly error and edge water seepage risk of the split frame. The continuous sealing design of the curved surface simultaneously improves the clarity of underwater vision and waterproof reliability, and eliminates the structural weakening caused by the replacement of independent lenses.
[0009] Furthermore, the outer wall of the mouthpiece mounting bracket is provided with a slot, a detachable mouthpiece is provided on one side of the mouthpiece mounting bracket, the inner wall of the mouthpiece is provided with a groove that matches the mouthpiece mounting bracket, and the mouthpiece is fastened to the connection of the mouthpiece mounting bracket by a cable tie.
[0010] By adopting the above technical solution, the bite nozzle is fitted with the bite nozzle mounting bracket groove through the groove to provide an axial anti-displacement barrier. The split interlocking mechanism reduces the replacement cost of a single bite nozzle. The groove depth is precisely matched to the shrinkage deformation of the bite nozzle, ensuring the structural stability under high vibration environment.
[0011] Furthermore, a secondary head clamp is provided on one side of the secondary head body, and the secondary head clamp is connected to the secondary head body by a buckle.
[0012] By adopting the above technical solution, the buckle connection between the secondary headband and the secondary head body achieves independent circumferential constraint on the head. The headband can be replaced independently if it breaks. The ratchet locking mechanism of the buckle provides a single-handed blind operation fastening force, freeing the user from the constraints of the mask body.
[0013] Furthermore, a drain valve is provided on the front side of the secondary head body, and the drain valve is fixedly installed on the secondary head body by a snap fastener.
[0014] By adopting the above technical solutions, the low-position layout at the front of the drain valve accurately receives the gravity water from the nasal mask, the optimized fluid path design significantly shortens the flow path, and the split flow channel architecture avoids water resistance accumulation in complex bending structures, thereby improving the drainage response speed.
[0015] Furthermore, a drain pipe is provided on the lower side of the secondary head body, and the drain pipe is fluidly connected to a drain valve.
[0016] By adopting the above technical solution, the drainage pipe and the secondary head are integrally injection molded, eliminating the risk of leakage at the pipe joint. The horizontal flow channel design of the U-shaped flat bend structure utilizes the gas-liquid interface tension to form a self-locking water seal, which physically blocks backflow during non-drainage periods, significantly outperforming the traditional downward bend structure that relies on gravity for drainage.
[0017] Furthermore, air inlet pipes are symmetrically installed on both sides of the secondary head body, and the inner wall of the air inlet pipes is provided with connecting threads.
[0018] By adopting the above technical solution, the intake pipe is separately embedded on both sides of the secondary head body. The dual independent air supply design maintains the minimum survival breathing volume when one side is blocked. The separate embedded structure eliminates the risk of hooking the protruding pipe opening and improves adaptability to complex environments.
[0019] Furthermore, an air tube is provided on one side of the secondary head body, and a thread is provided on the outer wall of one end of the air tube. The air tube is connected to the inner wall thread of the air inlet pipe through the thread on its outer wall.
[0020] By adopting the above technical solution, the gas tube is screwed to the air inlet pipe via a separate external thread, enabling independent replacement of the gas supply line. There is no need to discard the secondary head after a rupture. The modular design supports the separate switching of the gas cylinder tube and the water surface tube, expanding its applicability to multiple scenarios.
[0021] In summary, the present invention has the following main advantages:
[0022] 1. This utility model uses a support plate that rigidly abuts against the user's jawbone, transforming the impact force of water flow into the natural bearing capacity of the human skeleton. This breaks through the pain threshold limitation of traditional facial soft tissue pressure and achieves a revolutionary optimization of the mechanical transmission path. At the same time, the three-level stabilization system works in concert: the jaw support bears the longitudinal gravity, the secondary headband circumferentially restrains head displacement, and the mask band is distributed to fit the facial contours. In a turbulent environment, a spatial truss-like anti-overturning structure is constructed, enabling the device to maintain millimeter-level displacement accuracy of the mouthpiece breathing path in a surge environment, eliminating sealing failure and breathing interruption caused by device shaking.
[0023] 2. This utility model utilizes a directional drainage mechanism that allows water to seep into the mask's inner cavity from the outside, relying on a U-shaped horizontal flow channel in the drain pipe. This structure uses the gas-liquid interface tension to form a self-locking water seal, physically blocking backflow while accelerating water removal. The symmetrical redundant air supply design of the dual air inlets ensures a safe breathing flow threshold under unilateral blockage. Meanwhile, the modular architecture of the system achieves quick and easy disassembly without damage through threaded connections and slotted engagement, completely avoiding the irreparable defects of traditional integrated maintenance. The split sealing interface adopts a pre-pressurized adaptive sealing ring, maintaining static sealing integrity under deep water and high pressure, forming a reliable guarantee for the entire life cycle of industrial-grade diving equipment.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0030] In this embodiment:
[0031] A type of mouthpiece diving mask, such as Figure 1-4 As shown, a mouthpiece diving mask is characterized by: a mask body 1, a matching secondary head body 5 on the lower side of the mask body 1, a support plate 8 on one side of the secondary head body 5, the support plate 8 being connected to the secondary head body 5 via a support plate frame 9, a mouthpiece mounting bracket 15 at the breathing output end of the secondary head body 5, and a movable universal ball 14 at the midpoint between the mouthpiece mounting bracket 15 and the secondary head body 5. The separate matching design of the mask body 1 and the secondary head body 5 allows for independent maintenance of functional modules. Even if the mask body is damaged, the breathing unit can still be reused, significantly reducing the cost of use. The precision locking structure of the separate interface ensures watertightness and avoids irreversible damage to the body. At the same time, the support plate 8 is rigidly connected to the secondary head body 5 via the support plate frame 9, so that the jaw support force is transmitted independently of the mask, optimizing the mechanical distribution. The movable joint of the separate universal ball 14 between the mouthpiece mounting bracket 15 and the secondary head breaks through the angle limitation to match multi-directional head movement and eliminates temporomandibular strain caused by forced displacement of the mouthpiece.
[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4The mask body 1 has a goggle 2 on one side and a detachable mask strap 3 on one side. A nose shield 4 is fixedly connected to the lower side of the goggle 2 and extends into the inside of the mask body 1. The integrated structure of the goggle 2 and the mask body 1 forms a seamless optical curved surface, eliminating the assembly error and edge water seepage risk of the split frame. The continuous sealing design of the curved surface simultaneously improves the clarity of underwater vision and waterproof reliability, and prevents structural weakening caused by the replacement of independent lenses. At the same time, the nose shield 4 is fixed to the goggle 2 and extends into the inside of the mask to form an independent nasal cavity sealing cavity, which physically isolates the nasal cavity from water seepage while maintaining free breathing in the mouth. The integrated quick-adjustment mechanism of the detachable mask strap 3 works with the mask body 1 to dynamically distribute facial pressure, achieving dual optimization of ergonomic fit and high-pressure sealing.
[0033] See Figure 1 , Figure 3 , Figure 4 The outer wall of the bite mount 15 is provided with a slot, and a detachable bite 6 is provided on one side of the bite mount 15. The inner wall of the bite 6 is provided with a groove that matches the bite mount 15. The bite 6 is fastened to the connection of the bite mount 15 by a cable tie. The bite 6 is fitted into the slot of the bite mount 15 by the groove to provide an axial anti-displacement barrier. The split interlocking mechanism reduces the replacement cost of a single bite. The groove depth is precisely matched to the shrinkage deformation of the bite, ensuring the structural stability in high vibration environments. At the same time, the cable tie is fastened to the split connection to form a shear redundancy protection to avoid micro-leakage at the interface when the universal ball moves. The split design supports personalized bite customization and solves the incompatibility of traditional one-piece designs with tooth rows.
[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A secondary headband 7 is provided on one side of the secondary head body 5. The secondary headband 7 is connected to the secondary head body 5 by a buckle. The buckle connection between the secondary headband 7 and the secondary head body 5 achieves independent circumferential restraint of the head. The secondary headband 7 can be replaced independently if it breaks. The ratchet locking mechanism of the buckle provides a single-hand blind operation fastening force to free the body of the mask from restraint. At the same time, the elastic modulus of the secondary headband 7 is designed to match the curvature of the skull, dispersing pressure to the non-pain-sensitive area of the occipital tuberosity. The split anchoring system works with the mask band 3 to form a two-way anti-flow network, which reduces the turbulent displacement of the respirator.
[0035] See Figure 1 , Figure 2 , Figure 3A drain valve 13 is installed on the front side of the secondary head body 5. The drain valve 13 is fixedly installed on the secondary head body 5 by a snap-fit. The independent disassembly and cleaning design solves the problem of the whole machine's functional paralysis caused by algae blockage. The valve core and valve body are assembled separately in a modular manner, which reduces the maintenance cost of precision parts. At the same time, the snap-fit pre-pressure sealing ring structure maintains a static seal under high water pressure at the split interface, eliminating the progressive leakage failure caused by metal fatigue in traditional threaded connections and ensuring the system's sealing integrity during long-term use.
[0036] See Figure 1 , Figure 2 , Figure 4 A drain pipe 12 is provided on the lower side of the secondary head body 5. The drain pipe 12 is fluidly connected to the drain valve 13. The drain pipe 12 and the secondary head body 5 are integrally injection molded to eliminate the risk of leakage at the pipe connection seam. The horizontal flow channel design of the U-shaped flat bend structure utilizes the gas-liquid interface tension to form a self-locking water seal, which physically blocks backflow during non-drainage periods. This is significantly better than the traditional downward bend structure that relies on gravity drainage. At the same time, the integrated connection between the flat bend rate and the drain valve 13 precisely controls the fluid boundary layer separation effect, accelerating the discharge of high-viscosity water. The overall structure has no stress concentration points, can withstand the impact of deep water pressure pulsation, and avoids the fatigue fracture of the weld seam of the split U-shaped downward bend structure.
[0037] See Figure 1 The two sides of the main body 5 of the secondary head are symmetrically fitted with air inlet pipes 10. The inner wall of the air inlet pipes 10 is provided with connecting threads. The air inlet pipes 10 are separately fitted on both sides of the main body 5 of the secondary head. The dual independent air supply design maintains the minimum survival breathing volume when one side is blocked. The separate fitting structure eliminates the risk of hooking the protruding pipe opening and improves the adaptability to complex environments. At the same time, the separate threaded interface on the inner wall is compatible with the standard air tube 11 for tool-free quick installation. The polymer coating on the thread sealing surface compensates for the metal expansion difference and ensures the airtightness of the separate connection under drastic temperature changes.
[0038] See Figure 1 , Figure 2 , Figure 3 The secondary head body 5 has an air tube 11 on one side. One end of the air tube 11 has a thread on its outer wall. The air tube 11 is connected to the inner wall thread of the air inlet pipe 10 through its outer wall thread. The air tube 11 is screwed to the air inlet pipe 10 through the external thread of the separate external thread, so that the air supply line can be replaced independently. There is no need to discard the secondary head after it breaks. The modular design supports the separate switching of the gas cylinder tube and the water surface tube, expanding the applicability of multiple scenarios.
[0039] The implementation principle of this embodiment is as follows: When the user wears the diving mask, the mask body 1 is fixed to the face by the mask strap 3, so that the goggles 2 fit the eyes to provide a field of vision. At the same time, the nose mask 4 covers the nose to form a sealed area. During breathing, the external air source is delivered through the air tube 11 and introduced into the interior of the secondary head body 5 through the air inlet pipe 10. After the air flows through the breathing passage of the secondary head body 5, it is transmitted to the mouthpiece 6 through the mouthpiece mounting bracket 15 connected by the universal ball 14. The flexible structure of the universal ball 14 supports the mouthpiece 6 to be adjusted at multiple angles to adapt to oral movements. At the same time, the support plate 8 is pressed against the lower jaw to disperse water pressure through the support plate bracket 9. The secondary head strap 7 is put on the user's head and is fastened to the secondary head body 5 to form a stable system. At the same time, when water enters the secondary head body, the water is discharged through the drain valve 13 through the drain pipe 12. The interlocking of the mouthpiece 6 and the mouthpiece mounting bracket 15, the tightening of the straps, and the threaded interlocking of the air tube 11 and the air inlet pipe 10 together ensure underwater airtightness.
