Description

Technical Field

[0001] This invention relates to the field of lung volume training technology, specifically to a blowing resistance adjustment mechanism and a lung volume training device containing the mechanism. Background Technology

[0002] Lung volume training devices are important equipment in the field of respiratory rehabilitation, widely used in patients with chronic obstructive pulmonary disease, postoperative rehabilitation groups, and respiratory muscle strength enhancement training. Their core principle is to provide controllable blowing resistance to guide users in standardized deep breathing exercises, thereby strengthening respiratory muscles, improving lung ventilation efficiency, and reducing the risk of pulmonary complications.

[0003] Currently, most lung volume training devices on the market have a fixed blowing resistance value, which cannot be flexibly adjusted according to the user's rehabilitation stage, tolerance, and training goals. This design has obvious drawbacks: for beginners or patients with more severe conditions, a fixed high resistance can easily lead to excessive fatigue of the respiratory muscles, and even cause discomfort such as chest tightness and shortness of breath; while for those in the later stages of rehabilitation or healthy individuals, a fixed low resistance cannot achieve effective training intensity and makes it difficult to achieve the expected rehabilitation effect. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an air resistance adjustment mechanism and a lung volume training device containing the mechanism, which can effectively solve the problem of resistance being difficult to adjust in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a blowing resistance adjustment mechanism, including an adjustment tube, and further comprising: The piston plate is slidably disposed within the regulating tube; A multi-stage resistance assembly for adjusting the resistance when the piston plate moves upward includes multiple resistance rings disposed on the piston plate, adjacent resistance rings being slidably connected, and resistance springs being provided at the slidable connections; the adjusting tube is provided with an adjusting element for adjusting the direction of the resistance springs. Except for the bottommost resistance ring, there are blocking elements between the remaining adjacent resistance rings. The blocking elements restrict the relative sliding of the adjacent resistance rings. When the bottommost resistance ring moves up to the highest point of the sliding connection, the restriction of the resistance elements on its adjacent resistance rings is released.

[0006] Furthermore, the resistance ring includes a first resistance ring, a second resistance ring, and a third resistance ring, which are concentrically arranged and have progressively smaller diameters.

[0007] Furthermore, the second resistance ring has a plurality of vertical first grooves distributed in a ring on its sidewall. A rotating plate is rotatably installed in the first groove.

When the piston plate moves up and down, the indicator plate rotates.

[0014] Furthermore, an indicator groove is provided on the top wall of the regulating tube, and a pointer is provided in the indicator groove.

[0023] 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. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] The present invention will be further described below with reference to embodiments. Example 1:

[0025] refer to Figure 4 An air resistance adjustment mechanism includes an adjustment tube 1 and a piston plate 2, which is slidably disposed in the adjustment tube 1.

[0026] And a multi-stage resistance assembly for adjusting the resistance when the piston plate 2 moves upward. This assembly includes multiple resistance rings disposed on the piston plate 2, including a first resistance ring 8, a second resistance ring 9, and a third resistance ring 10. The first resistance ring 8, the second resistance ring 9, and the third resistance ring 10 are concentrically arranged, with their diameters decreasing sequentially. Adjacent resistance rings are slidably connected, and a resistance spring 15 is provided at the sliding connection. Multiple vertical first grooves 13 are annularly distributed on the side wall of the second resistance ring 9. A rotating plate 14 is rotatably mounted in the first groove 13. The resistance spring 15 is mounted on the bottom wall of the rotating plate 14. An auxiliary plate 16 is fixedly installed at the bottom of the 15. An adjusting component for adjusting the direction of the resistance spring 15 is provided in the adjusting tube 1. The adjusting component includes a driving airbag set in the first slide groove 13. The driving airbag and the rotating plate 14 are fixedly connected. When the driving airbag expands, the rotating plate 14 rotates and rotates the resistance spring 15 out of the first slide groove 13. An mounting plate 27 is provided on the top wall of the adjusting tube 1. An adjusting airbag 28 with the same number as the first slide groove 13 is provided on the mounting plate 27. The multiple adjusting airbags 28 and the multiple driving airbags are connected one-to-one. Magnets that attract each other are provided at the top and bottom of the adjusting airbags 28 respectively.

[0027] like Figure 4 As shown, multiple resistance rings are set inside the regulating tube 1 in the form of a sleeve. When air is introduced at the bottom of the regulating tube 1, the piston plate 2 gradually moves upward, thereby causing the resistance rings to move upward. Taking the first resistance ring 8 and the second resistance ring 9 as examples, when the piston plate 2 moves upward, the first resistance ring 8 moves upward, causing the first slide plate 11 to move upward and squeeze the resistance spring 15 in the first slide groove 13. Different exhalation resistance effects are obtained according to the number of resistance springs 15 in use.

[0028] The specific adjustment method for the working quantity of resistance spring 15 is as follows: Pressing the regulating airbag 28 above the regulating tube 1 causes air in the regulating airbag 28 to enter the corresponding driving airbag, causing the airbag to expand and push the resistance spring 15 to rotate out of the first slide groove 13. Thus, in subsequent training, when the first resistance ring 8 moves upward after gas is introduced into the regulating tube 1, the first slide plate 11 will not squeeze the resistance spring 15. When all the resistance springs 15 are moved out, the resistance at this time mainly comes from the friction force of the piston plate 2 moving upward.

[0029] The adjustment method between the second resistance ring 9 and the third resistance ring 10 is also the same, such as... Figure 7 In the process described above, the resistance spring 15 in the second slide groove is also adjusted using the corresponding adjusting airbag 28. Alternatively, the resistance springs 15 in the first and second slide grooves located on the same side can be driven simultaneously. Figure 7As shown, the driving airbags on the same side are connected to the same adjusting airbag 28, enabling the pressure of a single adjusting airbag 28 to drive the position adjustment of multiple resistance springs 15. This allows for different expiratory resistance training for different patients. Example 2:

[0030] refer to Figure 5 and Figure 6 Except for the bottommost resistance ring, there are blocking elements between the remaining adjacent resistance rings. These blocking elements restrict the relative sliding of adjacent resistance rings. When the bottommost resistance ring moves to the highest point of the sliding connection, the restriction of the resistance element between it and its adjacent resistance ring is released. The blocking elements include a second sliding plate 12 installed on the second resistance ring 9, and a second sliding groove adapted to the second sliding plate 12 on the third resistance ring 10. An adjusting groove 19 is provided in the second sliding plate 12, and a retaining plate 20 is slidably disposed in the adjusting groove 19. A return spring is provided at the sliding connection. The groove is provided with a slot that matches the card plate 20. The blocking component also includes a first sliding plate 11 installed on the first resistance ring 8. The first sliding plate 11 and the first sliding groove 13 are matched. A release plate 17 is installed on the first sliding plate 11. The release plate 17 and the first sliding plate 11 slide up and down synchronously. When the release plate 17 moves up to the second sliding plate 12, it squeezes the card plate 20 to separate from the slot. A release rod 18 is provided on the top of the release plate 17. A release groove 21 is provided on the bottom wall of the card plate 20. The release groove 21 is wedge-shaped. A through hole 22 is provided on the bottom wall of the second sliding plate 12.

[0031] The bottommost resistance ring (first resistance ring 8) can always slide freely up and down, while starting from the second resistance ring from the bottom, it will be hindered by the resistance components. The specific working process of the resistance components is as follows: Figure 6 As shown, when the first resistance ring 8 moves upward, the first slide plate 11 moves upward together with the release plate 17 and the release rod 18 until the release rod 18 moves to the position of the second slide plate 12. By squeezing the release groove 21, the locking plate 20 slides, causing the locking plate 20 to separate from the locking groove. At this time, the second slide plate 12 can slide upward in the second slide groove. This makes the resistance increase more stably in a step-like manner, making the training more stable.

[0032] The slot is located at the bottom of the second slide. If other resistance rings are slidably installed above the third resistance ring, a release plate 17 will also be provided on one side of the second slide plate 12, which is horizontally offset from the slot in the second slide, that is, the release plate 17 is located above the slot.

[0033] like Figure 4As shown, a threaded tube 3 is fixedly installed on the top of the piston plate 2, an indicator plate 5 is rotatably installed on the inner top wall of the adjusting tube 1, and a threaded rod 4 adapted to the threaded tube 3 is fixedly installed on the bottom wall of the indicator plate 5. When the piston plate 2 moves up and down, the indicator plate 5 rotates. A rotating ring 7 is rotatably installed on the bottom wall of the indicator plate 5, and the topmost resistance ring is fixedly connected to the rotating ring 7. An indicator groove 6 is opened on the top wall of the adjusting tube 1, and a pointer is provided in the indicator groove 6.

[0034] When the piston plate 2 moves upward, the threaded tube 3 moves upward, driving the threaded rod 4 to rotate through the threaded transmission, causing the indicator plate 5 to rotate, and the pointer is used to observe the height to which the internal piston plate 2 has risen. Example 3:

[0035] refer to Figure 1 and Figure 2 A lung volume training device employs an air resistance adjustment mechanism, including a trainer 29 and a mounting slot 33 formed on the trainer 29. Multiple mounting slots 33 are provided, and an adjustment tube 1 is installed in the mounting slot 33. An air outlet adjustment component is provided at the bottom of the trainer 29 for adjusting the air outlet speed of the adjustment tube 1. The air outlet adjustment component includes a vent head 23 connected to the air outlet end of the air outlet tube. A vent hole 24 is formed on the vent head 23, and an adjustment cover 25 is rotatably mounted on the vent head 23. Multiple adjustment holes 26 are formed on the adjustment cover 25, arranged in a ring shape, and all holes have different diameters.

[0036] By rotating the valve, different adjustment holes 26 can be aligned with or offset from the vent hole 24, thereby adjusting the actual vent diameter. Alternatively, the vent hole 24 can be blocked.

[0037] The mounting slot 33 has connecting slots 34 on both sides. Two connecting pipes 35 are symmetrically connected to the bottom side wall of the adjusting pipe 1. The trainer 29 is connected to the air blowing pipe 30 and has an air outlet pipe. When the adjusting pipe 1 is inserted into the mounting slot 33, the two connecting pipes 35 are connected to the air blowing pipe 30 and the air outlet pipe respectively. The air blowing pipe 30 is connected to a water separator 31, and an air cover 32 is connected to the water separator 31. A connecting component is provided between the water separator 31 and the air cover 32.

[0038] The entire training device 29 is made of transparent material, making it easy to observe the aforementioned pointers and other components. The adjustment tube 1 is installed via an insertion method, and during the insertion process, it is connected to the internal air outlet tube and air blowing tube 30 (e.g., ...). Figure 3 (Connection method).

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
