Description

Technical Field

[0001] This invention belongs to the technical field of hydrogen absorption equipment, and relates to a helmet-type hydrogen absorption device. Background Technology

[0002] Hydrogen has important uses and significance in medicine. Medical research has confirmed that hydrogen can effectively eliminate free radicals in the human body, thereby achieving the purpose of health preservation. As a selective antioxidant, in addition to its antioxidant therapeutic effects on many diseases, hydrogen also has a significant effect on timely removal of free radicals and improvement of immunity in healthy individuals. Currently, due to factors such as air quality, water quality, and lack of sleep, many people have weakened immunity and are in a sub-healthy state. Therefore, hydrogen-absorbing glasses, earplugs, and masks for inhaling hydrogen into the eyes have emerged. Wearing these devices creates a sealed space in the affected area, and when combined with a hydrogen generator, hydrogen is introduced into this tiny sealed space to remove oxidative free radicals and improve immunity.

[0003] However, currently available hydrogen inhalation masks, earplugs, and goggles only allow for hydrogen contact in a localized area of ​​the head. Furthermore, the varying power levels of hydrogen production equipment result in inconsistent hydrogen concentrations. Additionally, the limited size of the enclosed space and the difficulty in adjusting the concentration can lead to excessively high hydrogen concentrations and pressures in areas such as the eyes and eardrums, causing discomfort to the user. Moreover, current hydrogen inhalation devices generally lack automatic exhaust mechanisms that adjust the exhaust volume according to the pressure within the enclosed space, potentially causing excessively high pressure and harm to the user.

[0004] To address the above problems, this invention proposes a helmet-type hydrogen inhalation device. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a helmet-type hydrogen inhalation device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A helmet-type hydrogen inhalation device includes a helmet body and a face mask; the helmet body and face mask are rotatably connected by a rotating shaft, and the helmet body and face mask are in sealed contact and form a accommodating cavity; an air outlet is provided on the rotating shaft to communicate the accommodating cavity with the outside; a trumpet-shaped rubber ring is provided in the air outlet, with the larger end of the rubber ring facing the accommodating cavity; a first driving component is provided in the air outlet, and when the gas pressure in the accommodating cavity is too high, the first driving component drives the smaller end of the rubber ring to enlarge; an air inlet channel is provided on the face mask.

[0008] Furthermore, an air intake assembly is provided in the air intake channel. The air intake assembly includes a fixed disk fixed in the air intake channel and a rotating disk that is rotatably disposed therein. Both the rotating disk and the fixed disk are provided with air holes. The air intake channel is connected to an air intake hose. A second drive assembly is provided between the air intake hose and the air intake assembly.

[0009] Furthermore, the second drive assembly includes a pull rod; a limiting groove is formed on the rotating surface of the pull rod, the limiting groove including a straight groove section and a spiral groove section; the axis of the spiral groove section coincides with the axis of the pull rod, and both ends of the spiral groove section are connected to the straight groove section, which is parallel to the axis of the pull rod; both the rotating disk and the fixed disk have coaxially formed connecting holes, and the upper end of the pull rod passes through the rotating disk and the fixed disk in sequence; a guide ball is fixedly connected to the inner wall of the connecting hole on the fixed disk, and the guide ball is slidably disposed in the limiting groove; a blocking block is slidably disposed in the air intake channel; a rubber tube is connected to the upper end of the air intake hose, and the rubber tube passes through the blocking block and is fixedly connected to the pull rod; and the rubber tube is fixedly connected to the blocking block; an air intake is formed in the part of the rubber tube located between the blocking block and the rotating disk.

[0010] Furthermore, a limiting post is coaxially fixed in the middle section of the intake channel, and a conical hole is coaxially opened on the limiting post, with the tip of the conical hole facing downward; the blocking block is an inverted frustum shape and fits with the conical hole; the lower part of the blocking block is composed of multiple elastic petals, which are evenly distributed around the axis of the blocking block, and the middle of the multiple elastic petals forms a through hole, and the upper end of the rubber tube passes through the through hole and is fixed to the blocking block.

[0011] Furthermore, the first drive component includes a baffle and a movable plate;

[0012] A support column is fixed on the inner wall of the vent. A baffle is slidably connected to the support column, and the baffle is located on one side of the small end of the rubber ring and opposite to the small end of the rubber ring. One end of the movable plate is hinged to the small end of the rubber ring through a first hinge shaft, and the other end of the movable plate is hinged to the baffle through a second hinge shaft. A sliding hole is provided on the movable plate, and a first sliding rod is slidably connected in the sliding hole. The first sliding rod is cylindrical and is fixedly connected to the inner wall of the vent through a support rod. The first hinge shaft and the second hinge shaft are parallel to each other and are both perpendicular to the axis of the rotating shaft. The baffle, the rubber ring, and the rotating shaft are coaxial. The distance from the first sliding rod to the axis of the rubber ring is greater than the distance from the first hinge shaft to the axis of the rubber ring and less than the distance from the second hinge shaft to the axis of the rubber ring.

[0013] Furthermore, sealing strips are fixed to both the helmet body and the face mask.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the user wears the device, their head is sealed within the cavity, which is then filled with hydrogen gas. The user's head, eyes, ears, and other organs can simultaneously inhale hydrogen, allowing the hydrogen gas to circulate and penetrate every corner of the brain, including every hair follicle. This provides the user with effective, safe, and comfortable hydrogen therapy, boosting immunity. Furthermore, because the gas source is the same, the hydrogen concentration absorbed by the user's face, eyes, ears, and other areas is consistent, avoiding the uneven hydrogen concentration that can occur when different areas are inhaled separately.

[0016] 2. When the gas pressure inside the accommodating cavity is too high, the gas passing through the rubber ring impacts the baffle, causing the baffle to expand outward through the movable plate, thereby increasing the diameter of the lower end of the rubber ring and allowing the gas to flow out faster. This has the function of automatically regulating the internal pressure of the accommodating cavity.

[0017] 3. If the hydrogen supply is too fast or the user feels uncomfortable, pull down the intake hose to allow the blocking block to enter the conical orifice, reducing the diameter of the rubber hose and slowing down the hydrogen intake speed. To stop the hydrogen supply, continue pulling the intake hose. Under the action of the spiral groove section, the rotating disc will rotate, gradually displacing the first and second air holes, thus closing the intake passage. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-12 As shown, the technical solution adopted by this invention is as follows: A helmet-type hydrogen inhalation device includes a helmet body 1 and a face mask 2. The helmet body 1 is injection molded and made of PP or PC. The helmet body 1 and the face mask 2 are rotatably connected by a pivot 3, and the helmet body 1 and the face mask 2 are in sealed contact and form a cavity. Sealing strips 5 are fixed on both the helmet body 1 and the face mask 2. The sealing strip 5 can be made of medical-grade silicone. When the device is worn on the user's head, the face mask 2 is rotated so that it completely covers the user's face. The edges of the helmet body 1 and the face mask 2 are in contact with the user's skin through the sealing strips 5, forming a sealed space within the cavity. An openable breathing hole is provided on the helmet body 1 or the face mask 2 to facilitate the user's access to sufficient oxygen.

[0033] The helmet body 1 has a rotating shaft 3 fixedly installed on both sides, and a connecting block 4 is rotatably sleeved on each rotating shaft 3. The connecting block 4 is fixedly connected to the face mask 2.

[0034] An axial vent is provided on the rotating shaft 3, allowing the accommodating cavity to communicate with the outside. A trumpet-shaped rubber ring 19 is fixed inside the vent, with the larger end of the rubber ring 19 facing the accommodating cavity. The rubber ring 19 is coaxial with the rotating shaft 3. Gas in the accommodating cavity enters the vent through the rubber ring 19 and exits from the vent.

[0035] A first driving component is provided inside the rotating shaft 3 on one side of the small opening of the rubber ring 19. When the gas pressure in the accommodating cavity is too high, the first driving component causes the small opening of the rubber ring 19 to expand outward, making the gas in the accommodating cavity flow out more quickly.

[0036] The first drive assembly includes a movable plate 22 and a baffle 26.

[0037] Pull rings 20 are fixedly provided on both the upper and lower sides of the small end of the rubber ring 19, and each pull ring 20 is fixedly connected to a first hinge shaft 21. A support column 28 is fixedly connected to the inner wall of the vent, and a through hole is provided on the support column 28. A second slide rod 27 is slidably connected to the support column 28 through the through hole. The baffle 26 is fixedly connected to the end of the second slide rod 27 facing the rubber ring 19. In this embodiment, there are two through holes, and correspondingly two second slide rods 27. A spring 29 is fixedly connected between the spring 29 and the support column 28.

[0038] There are two movable plates 22, each corresponding to one of the two pull rings 20. One end of each movable plate 22 is rotatably connected to the corresponding first hinge shaft 21, and the other end of each movable plate 22 is hinged to the baffle 26 via a second hinge shaft 25. A sliding hole 23 is provided on each movable plate 22. Support rods 24 are provided on both sides of each movable plate 22, and the support rods 24 are fixed to the inner wall of the air outlet. A first sliding rod is fixedly connected between the two support rods 24, and the first sliding rod is slidably disposed within the sliding hole 23. The first sliding rod is cylindrical, allowing the movable plate 22 to rotate relative to the first sliding rod. The first hinge shaft 21, the second hinge shaft 25, and the first sliding rod are parallel to each other and all perpendicular to the axis of the rotating shaft 3. The baffle 26 is coaxial with the rubber ring 19. The distance from the first sliding rod to the axis of the rubber ring 19 is greater than the distance from the first hinge shaft 21 to the axis of the rubber ring 19 but less than the distance from the second hinge shaft 25 to the axis of the rubber ring 19.

[0039] When the gas pressure inside the accommodating cavity is too high, the gas impacts the baffle 26 after passing through the rubber ring 19, causing the baffle 26 to move closer to the support column 28. The baffle 26 pulls the movable plate 22, which in turn pulls the rubber ring 19, causing it to deform axially. Simultaneously, the movable plate 22 moves along the first sliding rod, causing the end of the movable plate 22 near the first hinge shaft 21 to gradually move away from the axis of rotation 3, gradually expanding the small opening of the rubber ring 19 and increasing its diameter, thus accelerating the outflow of gas.

[0040] A mounting block 6 is fixedly connected to the lower part of the mask 2, and an air intake channel 7 is provided on the mounting block 6. The lower part of the air intake channel 7 is connected to the air intake hose 8, and the device for providing hydrogen is connected to the accommodating cavity through the air intake hose 8 and the air intake channel 7. An air intake assembly is provided inside the air intake channel 7, and the air intake assembly is sealed to the air intake channel 7. The air intake assembly includes a rotating disk 15 and a fixed disk 16. The fixed disk 16 is coaxially rotatably disposed inside the air intake channel 7. Specifically, a rotating groove is provided on the inner wall of the air intake channel 7, and the air intake channel 7 is rotatably disposed in the rotating groove. The rotating disk 15 is fixedly connected to the inner wall of the air intake channel 7. Both the rotating disk 15 and the fixed disk 16 are provided with air holes 17. Assuming that the air hole 17 on the rotating disk 15 is the first air hole 1701, and the air hole 17 on the fixed disk 16 is the second air hole 1702, the distance from the first air hole 1701 to the axis of the rotating disk 15 is equal to the distance from the second air hole 1702 to the axis of the fixed disk 16. In this embodiment, there are four first air holes 1701, which are evenly distributed around the circumference of the rotating disk 15. There are also four second air holes 1702, which are evenly distributed around the circumference of the fixed disk 16. Each of the four first air holes 1701 corresponds to one of the four second air holes 1702.

[0041] When the first vent 1701 and the second vent 1702 are aligned, the intake channel 7 is opened, and hydrogen gas can enter the accommodating cavity through the intake hose 8 and the intake channel 7. When the first vent 1701 and the second vent 1702 are misaligned, the intake channel 7 is blocked.

[0042] A second drive assembly is provided between the air intake assembly and the air intake hose 8. When the user feels that the gas pressure in the accommodating cavity is too high and uncomfortable, he pulls the air intake hose 8. The air intake hose 8 causes the rotating disk 15 to rotate through the second drive assembly, so that the area opposite the first air hole 1701 and the second air hole 1702 gradually decreases, thereby reducing the amount of gas passing through the air hole 17 and reducing the amount of gas entering the accommodating cavity.

[0043] The second drive assembly includes a pull rod 13. A limiting groove 14 is formed on the rotating surface of the pull rod 13, comprising a straight groove section and a spiral groove section. The axis of the spiral groove section coincides with the axis of the pull rod 13, and both ends of the spiral groove section are connected to straight groove sections, which are parallel to the axis of the pull rod 13. Both the rotating disk 15 and the fixed disk 16 have coaxially formed connecting holes 18, through which the upper end of the pull rod 13 passes sequentially. A guide ball is fixedly connected to the inner wall of the connecting hole 18 on the fixed disk 16, and the guide ball is slidably disposed within the limiting groove 14. A blocking block 10 is slidably and sealed within the air intake channel 7. A rubber tube 9 is connected to the upper end of the air intake hose 8, and the rubber tube 9 passes through the blocking block 10 and is fixedly connected to the pull rod 13. The rubber tube 9 is also fixedly connected to the blocking block 10. An air inlet 12 is formed in the portion of the rubber tube 9 located between the blocking block 10 and the rotating disk 15.

[0044] Hydrogen gas enters the intake channel 7 through the intake hose 8, rubber hose 9, and intake port 12, and then enters the accommodating cavity through the first vent 1701 and the second vent 1702. In this embodiment, the rubber hose 9 and the blocking block 10 are threadedly connected.

[0045] A limiting post is coaxially fixed in the middle section of the air intake channel 7. A conical hole 11 is coaxially opened on the limiting post, with the tip of the conical hole 11 facing downward. The blocking block 10 is an inverted frustum shape. The lower part of the blocking block 10 is composed of multiple elastic petals. The multiple elastic petals are evenly distributed around the axis of the blocking block 10, and the middle of the multiple elastic petals forms a through hole. The rubber tube 9 passes through the through hole and is threadedly connected to the blocking block 10.

[0046] Pulling the intake hose 8 downwards causes the blocking block 10 to move downwards. Under the action of the conical hole 11, the blocking block 10 is squeezed and its radial dimension decreases. The blocking block 10 further squeezes the rubber tube 9, causing the rubber tube 9 to deform, thereby reducing the flow rate of hydrogen.

[0047] In this embodiment, there are two air intake channels 7, each equipped with an air intake component and connected to an air intake hose 8. Each air intake hose 8 is connected to a corresponding air intake component via a second drive component. This allows for more precise adjustment of the hydrogen inflow rate and a wider adjustment range.

[0048] Working principle: Initially, the first air hole 1701 and the second air hole 1702 are vertically opposite each other, and the air intake channel 7 is in the open state. The guide ball is located within the straight groove section at the bottom of the limiting groove 14. The blocking block 10 is located above the conical hole 11. The rubber ring 19 is in its natural state, and the first sliding rod is located at the end of the sliding hole 23 near the baffle 26.

[0049] When in use, put the helmet body 1 on your head, and then rotate the mask 2 downwards around the pivot 3 so that the mask 2 completely covers the user's face. At this time, the sealing strip 5 fits against the user's skin, and the user's head is sealed in the cavity.

[0050] Then, the inlet hose 8 is connected to the hydrogen supply device, allowing hydrogen to enter the inlet channel 7 through the inlet hose 8, rubber hose 9, and inlet 12, and then enter the receiving cavity through the first air hole 1701 and the second air hole 1702. The receiving cavity gradually fills with hydrogen, allowing the user's head, eyes, ears, and other organs to inhale hydrogen simultaneously. This allows the hydrogen to circulate and penetrate every corner of the head and brain, including every hair follicle, providing the user with effective, safe, and comfortable hydrogen therapy and improving immunity. Furthermore, because the gas source is the same, the hydrogen concentration absorbed by the user's face, eyes, ears, and other areas is consistent, avoiding the situation where different areas receive hydrogen inhalation separately, resulting in different hydrogen concentrations.

[0051] As hydrogen gradually enters the cavity, the pressure inside the cavity gradually increases. The gas in the cavity flows out through the rubber ring 19 and the rotating shaft 3, allowing the hydrogen to circulate and maintaining a suitable pressure inside the cavity.

[0052] Under suitable air pressure, the gas flows towards the baffle 26 after passing through the rubber ring 19, but not enough to make the baffle 26 overcome the elastic force of the spring 29 and move closer to the support column 28. When the air pressure in the accommodating cavity is too high, the gas flow rate increases. When the gas passes through the rubber ring 19 and impacts the baffle 26, the baffle 26 overcomes the elastic force of the spring 29 and moves closer to the support column 28. The baffle 26 pulls the movable plate 22 to move, and the movable plate 22 pulls the rubber ring 19 to stretch and deform. At the same time, the movable plate 22 moves along the first sliding rod and rotates around the second hinge axis 25, causing the end of the movable plate 22 near the first hinge axis 21 to gradually move outward, causing the small end of the rubber ring 19 to deform outward, accelerating the gas outflow and reducing the air pressure in the accommodating cavity.

[0053] As the air pressure in the accommodating cavity gradually decreases, the impact of the gas on the baffle 26 decreases. Under the action of the spring 29, the baffle 26 moves towards the rubber ring 19. The movable plate 22 moves along the first sliding rod, causing the end of the movable plate 22 near the baffle 26 to gradually approach the first sliding rod, so that the rubber ring 19 gradually returns to its original state.

[0054] If the hydrogen supply is too fast, or if the gas pressure in the containment cavity increases too quickly, causing discomfort to the user, the user can pull the inlet hose 8. The inlet hose 8 will move the rubber tube 9 outward, thereby causing the blocking block 10 to move into the conical hole 11. As the diameter of the conical hole 11 gradually decreases, the blocking block 10 is squeezed and deformed inward, further squeezing the rubber tube 9, causing the diameter of the rubber tube 9 to shrink, thus reducing the speed at which hydrogen flows in.

[0055] At the same time, the rubber tube 9 pulls the lever 13 downward, and the straight groove section of the limiting groove 14 contacts the guide ball on the rotating disk 15.

[0056] If the user still feels uncomfortable and needs to further reduce the hydrogen supply rate or stop the hydrogen supply, the intake hose 8 can be pulled further, causing the blocking block 10 to move further into the conical hole 11, and the pull rod 13 to continue moving downwards. When the spiral groove section of the limiting groove 14 passes the rotating disk 15, the rotating disk 15 rotates under the action of the spiral groove section, causing the first air hole 1701 and the second air hole 1702 to gradually shift apart, and the area opposite the first air hole 1701 and the second air hole 1702 to gradually decrease, further reducing the hydrogen flow rate. Until the intake channel 7 is closed, hydrogen can no longer enter the accommodating cavity. When the first air hole 1701 and the second air hole 1702 are completely shifted apart, the straight groove section at the upper end of the limiting groove 14 cooperates with the guide ball to prevent the first air hole 1701 and the second air hole 1702 from facing each other again and opening the intake channel 7 when the user continues to pull the intake hose 8.

[0057] Meanwhile, due to the excessively high gas pressure inside the cavity, the small end of the rubber ring 19 expands outward, allowing hydrogen to flow out quickly, which further reduces the gas pressure inside the cavity rapidly.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
