Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0025] Example: See Figure 1 - Figure 3 This embodiment relates to a breathing training mask, specifically used to help users train their breathing function, improve respiratory muscle strength and lung capacity, etc. This mask allows for flexible adjustment of training intensity based on the user's specific situation by adjusting breathing resistance, thereby achieving personalized training effects. Specifically, it includes a sealing cover 11 and a breathing section 12. The sealing cover 11 is provided with a fixing strap 13 that is fixed to the user's head. The sealing cover 11 and the breathing section 12 are detachably connected. The breathing section 12 is detachably connected to a breathing assembly 14 with adjustable breathing resistance. The breathing assembly 14 includes an exhalation head 15 and an inhalation head 16.

[0026] Specifically, in this embodiment, the sealing cover 11 is fixed to the user's head by a fixing strap 13, ensuring a stable fit. The sealing cover 11 is detachably connected to the breathing unit 12, and the breathing unit 12 is detachably connected to the breathing assembly 14. The disassembly process is simple, allowing users to easily maintain the device and avoiding the inconvenience of cleaning traditional breathing training equipment. The breathing assembly 14 includes an exhalation head 15 and an inhalation head 16. The structural design of the breathing assembly 14 allows the breathing resistance to be adjusted according to the user's needs, meeting the training requirements of different users. By adjusting the resistance during exhalation and inhalation, users can gradually increase the training difficulty according to their physical condition and rehabilitation progress.

[0027] See Figure 4 In this embodiment, the breathing assembly 14 has a channel 21, within which a valve body 22 is slidably disposed. A compression spring 23 is located at one end of the valve body 22, and an adjusting bolt 24 for adjusting the compression of the spring 23 is located at the other end. The channel 21 has an internal thread 25 adapted to the threaded connection of the adjusting bolt 24. The channel 21 within the breathing assembly 14 is through-type, facilitating airflow during inhalation and exhalation. The spring closes the channel 21 by pushing the valve body 22. When inhaling or exhaling, the user needs to push the valve body 22 open by overcoming the spring pressure. The adjusting bolt 24 is threaded to the internal thread 25 of the channel 21, allowing the user to adjust the compression of the spring 23 by rotating the adjusting bolt 24. Rotating the adjusting bolt 24 changes the compression of the spring 23, thus affecting the position of the valve body 22 and the airflow. As the compression of the spring 23 increases, the valve body 22 is pressed against one end of the channel 21, restricting the airflow and increasing resistance during breathing. Conversely, reducing the compression of the spring 23 will cause the valve body 22 to return to its original position, increasing the opening of the channel 21 and reducing airflow resistance. The channel 21 is provided with a tapered opening 26, and the valve body 22 is spherical. The spring 23 pushes the valve body 22 into contact with the tapered opening 26 to achieve sealing and unidirectional flow.

[0028] In this embodiment, the sealing cover 11 has four sets of threaded holes 31 for connecting with the mounting base 17 of the breathing unit 12. Specifically, the mounting base 17 has through holes 33 corresponding to the positions of the threaded holes 31 on the sealing cover 11. Four sets of fixing bolts 34 (hollow) pass through the through holes 33 and can be threaded into the threaded holes 31 on the sealing cover 11. This design ensures a stable connection between the sealing cover 11 and the breathing unit 12 and enhances the sealing performance of the structure. In addition, the breathing unit 12 is equipped with a filter cotton core 35, which can effectively filter harmful substances in the air, such as dust and bacteria, so that the air inhaled by the user during breathing training is clean and safe.

[0029] See Figure 5 In this embodiment, the fixed base plate 17 is provided with a mounting sleeve 41 for mounting the breathing assembly 14. The mounting sleeve 41 has a mounting groove 42 on its wall. A buckle 43, which slides and adapts to the mounting groove 42, is provided on the outer side of the breathing assembly 14. The mounting groove 42 includes a guide section 44 arranged axially along the mounting sleeve 41 and a screw-in section 45 extending from the end of the guide section 44 and circumferentially along the mounting sleeve 41. A limiting part 46, adapted to the buckle 43, is provided at the end of the screw-in section 45. A return spring 47 is provided inside the mounting sleeve 41 for pushing the breathing assembly 14 outward. Specifically, during installation, the buckle 43 is first aligned with the guide section 44, and then pushed into the breathing assembly 14 along the direction of the guide section 44. After overcoming the elastic force of the return spring 47, the breathing assembly 14 is rotated to allow the buckle 43 to slide into the screw-in section 45 until the end of the screw-in section 45. After releasing, it engages with the limiting part 46 under the push of the return spring 47, thus realizing the installation of the breathing assembly 14. The disassembly process is the reverse. This structural design makes the installation and removal of the breathing assembly 14 simple and convenient.

[0030] See Figure 3 In this embodiment, the fixing strap 13 consists of two parts: an adjusting strap 51 that wraps around the back of the user's head when worn, and an elastic strap 52 that fits snugly against the top of the user's head when worn. The adjusting strap 51 is equipped with a D-ring 53 for adjusting the length. By adjusting the position of the D-ring 53, the length of the adjusting strap 51 can be flexibly adjusted to adapt to different head shapes and provide a comfortable wearing experience. One end of the elastic strap 52 is provided with a loop 54, and the adjusting strap 51 passes through the loop 54, making the connection between the two more secure and preventing slippage or loosening during wear. Furthermore, see... Figure 6 The sealing cover 11 is equipped with a clamp 55, while the elastic band 52 has several sets of limiting holes 56. The clamp 55 is threaded and adapted to the locking bolt 57. The locking bolt 57 can be screwed into the clamp 55 to fix the elastic band 52 to the clamp 55. Specifically, the wearing length of the elastic band 52 can be adjusted by inserting the locking bolt 57 into the limiting holes 56 at different positions to accommodate users with various head sizes.

[0031] In this embodiment, to avoid situations where excessive sealing of the mask leads to excessive adjustment of breathing resistance, causing breathing difficulties or even suffocation, the sealing cover 11 is symmetrically provided with four sets of vent holes 61, each set of vent holes 61 being fitted with a sealing plug 62. Furthermore, the sealing plugs 62 at two sets of vent holes 61 located on the same side of the sealing cover 11 are connected by a connecting strip 63. This design ensures that even with a strong seal, effective airflow can still be provided through the vent holes 61 in emergencies. When the user experiences breathing difficulties, they can quickly pull the connecting strip 63 to detach the sealing plug 62 from the vent hole 61, releasing airflow and thus alleviating breathing resistance and preventing the risk of suffocation. This provides an emergency response measure during mask use, improves safety, and ensures that the user is adequately protected during use.

[0032] When users wear masks for extended periods, the masks can become contaminated and damaged, especially the side that comes into direct contact with the user's face. In this embodiment, the sealing cover 11 is detachably connected to a flexible wearing ring 64 that fits snugly against the user's skin around the mouth and nose. When the wearing ring 64 becomes contaminated, it can be cleaned separately or replaced directly, protecting the user's facial skin and ensuring the hygiene and comfort of the mask. Furthermore, to ensure a tight seal, a sealing groove 65 is provided at the connection between the sealing cover 11 and the wearing ring 64, while a sealing strip 66 is provided on the wearing ring 64 that is press-fitted into the sealing groove 65.

[0033] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
