[0025] The utility model discloses a kind of masks for micro-high pressure oxygen cabin, which can collect and discharge carbon dioxide, and the utility model is further described below in conjunction with specific embodiments.

[0026] As shown in Figure 1 The mask for micro-high pressure oxygen cabin, which can collect and discharge carbon dioxide, has a mask body 1. The opening of the mask body 1 is provided with a silica gel pad 2. The left and right sides of the mask body 1 are respectively provided with strap rings 10, and a strap is installed between the strap rings 10 on the left and right sides. When a user wears the mask, the mask body 1 covers the user's mouth and nose, and the strap is fixed to the user's back of the head. The bottom of the mask body 1 is vertically provided with an air inlet end 11 and an air outlet end 12, and the air inlet end 11 is located in front of the air outlet end 12. The inside of the mask body 1 is provided with a gas collecting cover 3, and the gas collecting cover 3 is provided with a plurality of air outlet holes 30 facing the opening direction of the mask body 1. The air inlet end 11 is connected with the gas collecting cover 3 through a first pipe 31. The air outlet end 12 is communicated with the inside of the mask body 1.

[0027] In use, the air inlet end 11 is connected with the high-pressure oxygen pipe of the micro-high pressure oxygen cabin, the air outlet end 12 is connected with the exhaust pipe of the micro-high pressure oxygen cabin, the user can inhale pure oxygen in the cabin by using the mask, and the exhaled carbon dioxide can be collected and discharged quickly, thereby effectively improving the use effect of the micro-high pressure oxygen cabin.

[0028] To provide negative oxygen ions for the user, further improve the technical effect of the micro-high pressure oxygen cabin, as Figure 1 and Figure 2As shown, a second tube 32 may be provided in the mask body 1. A carbon brush inlet 33 is provided at the lower portion of the mask body 1, the upper end of the second tube 32 is connected to the gas collecting hood 3, and the lower end of the second tube 32 is connected to the carbon brush inlet 33. When negative oxygen ions need to be provided to the user, the carbon brush of the negative ion generator only needs to be inserted into the gas collecting hood 3 through the carbon brush inlet 33 and the second tube 32, and the wire of the carbon brush is located in the second tube 32. When high-pressure oxygen enters the gas collecting hood 3 from the first tube 31, the high DC voltage at the tip of the carbon brush bristles of the negative ion generator generates high corona, and a large number of electrons are released at a high speed. However, the electrons cannot exist in the air for a long time and will be immediately captured by oxygen molecules, thereby generating negative oxygen ions for the user to use.

[0029] In order to facilitate the insertion and removal of the carbon brushes of the negative ion generator and taking into account the convenience of wearing by the user, the carbon brush inlet 33 is located between the air inlet end 11 and the exhaust end 12.

[0030] like Figure 2 As shown, the mask body 1 has two strap rings 10 on each side, and the two strap rings 10 on the same side are arranged one above the other. A strap is installed between the upper left and right strap rings 10, and another strap is installed between the lower left and right strap rings 10. The upper and lower straps can improve the user's wearing comfort.

[0031] In order to facilitate the user to wear the mask and to enable the user to quickly adjust the tightness of the strap, Figure 3As shown, the strap consists of a left strap 6, a right strap 7, and a strap adjuster. The strap adjuster comprises a first housing 4 and a second housing 8. A strip-shaped hole 40 is defined in the top of the first housing 4, and a socket 42 is defined on the right side of the first housing 4. A guide rod 41 is mounted on the right side of the first housing 4, located above the socket 42. The left strap 6 is located on the left side of the first housing 4. A pawl 43 is mounted within the first housing 4, with its pivot axis located above the socket 42. A spring 45 is installed within the first housing 4, pushing the pawl 43 toward the socket 42. A C-shaped sleeve 5 is mounted on the outer periphery of the first housing 4. A slider 51 is located inside the C-shaped sleeve 5. The slider 51 engages with the strip-shaped hole 40 and defines the position between the C-shaped sleeve 5 and the first housing 4, ensuring that the C-shaped sleeve 5 can only slide linearly along the first housing 4. A pull cord 44 is mounted between the slider 51 and the pawl 43. The slider 51 is pulled by the pull cord 44 to swing the pawl 43 upward. A partition 82 is provided within the second housing 8. The partition 82 and the second housing 8 form a guide cavity 80, which cooperates with the guide rod 41. A rack 81 is provided on the left side of the second housing 8. The rack 81 is provided with a row of ratchet teeth 83. The rack 81 can be inserted into the first housing 4 through the insertion hole 42. The ratchet teeth 83 cooperate with the pawl 43. The right side of the second housing 8 is provided with a right strap 7. When the user puts on the mask, they first widen the distance between the first shell 4 and the second shell 8, stretching the straps to make it easier to put on the head. The specific operation is as follows: the user pinches the second shell 8 with one hand and pinches the C-shaped sleeve 5 with the other hand to pull it to the sides. During this process, the C-shaped sleeve 5 pulls the pawl 43 upward through the slider 51 and the pull rope 44. During the swinging process, the end of the pawl 43 moves from the root of the ratchet 83 to its end. At the same time, the distance between the C-shaped sleeve 5 and the second shell 8 is slightly reduced, usually by a few millimeters. When the pawl 43 separates from the ratchet 83, the distance between the C-shaped sleeve 5 and the second shell 8 increases rapidly under the action of the tension, thereby stretching the straps. After the user puts the mask on the mouth and nose, they only need to push the C-shaped sleeve 5 and the second shell 8 closer together to shorten the straps, thereby fixing the mask. To remove the mask, simply move the C-shaped sleeve 5 with one hand, first disengaging the pawl 43 from the ratchet teeth 83 through the sleeve. The straps can then be stretched to remove the mask. The guide cavity 80, in conjunction with the guide rod 41, guides the rack 81 while also strengthening the connection between the C-shaped sleeve 5 and the second housing 8. The C-shaped sleeve 5 and the second housing 8 can be completely separated and reconnected after separation. The end of the rack 81 is provided with a bevel 84, which facilitates smoother insertion of the rack 81 into the C-shaped sleeve 5.

[0032] In order to facilitate processing and manufacturing, as well as assembly, Figure 4As shown, the slider 51 is provided with a base plate 50, two fixed hooks 52 are symmetrically arranged on the base plate 50, the two fixed hooks 52 are respectively located on both sides of the slider 51, a matching hole 55 and two through holes 54 are formed on the C-shaped sleeve 5, the matching hole 55 is matched with the slider 51, the two through holes 54 are matched with the two fixed hooks 52 one by one, and the end inner side of the C-shaped sleeve 5 is provided with a convex edge 53. When assembling the first shell 4 and the C-shaped sleeve 5, the C-shaped sleeve 5 is first installed on the outer periphery of the first shell 4, the matching hole 55 is corresponded with the strip-shaped hole 40, then the slider 51 is sequentially inserted through the matching hole 55 and the strip-shaped hole 40; the fixed hook 52 has a certain elasticity, after the two fixed hooks 52 are respectively inserted into the corresponding through holes 54, the slider 51 and the C-shaped sleeve 5 can be fixed together.

[0033] The technical scheme of the utility model is not limited to the scope of the embodiments described in the utility model. The technical contents not described in the utility model are all known technologies.
