Description

Technical Field

[0001] The invention relates to the technical field of breathing training, and in particular to a breathing training device. Background Art

[0002] Breathing training is one of the ways to exercise human lung capacity. The human body exhales because the pressure in the lungs is greater than the atmospheric pressure. Normal exhalation does not produce muscle contraction, so breathing training is needed to enhance the intensity of lung muscle training, especially for the recovery of breathing ability, and regular exercise is required. In the process of breathing training, special breathing training equipment is generally used.

[0003] However, current conventional breathing training equipment lacks an intuitive display of training results, which makes it impossible to accurately record the breathing volume data during each training session, which is not conducive to the formulation and planning of subsequent breathing training plans. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a breathing training device to solve the above problems.

[0005] The purpose of the present invention is achieved through the following technical solutions:

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] like Figure 1-5 As shown, a breathing training device provided in this embodiment includes a chamber body 1, a mouth pad 2, a long column 3 and a driving mechanism 4.

[0037] See also Figure 2 A rotating shaft 11 is rotatably installed inside the warehouse body 1, and a plurality of blades 111 are evenly distributed circumferentially on the rotating shaft 11. A top opening 12 and a bottom opening 13 are respectively provided at the top and bottom ends of the warehouse body 1 on the same side of the rotating shaft 11. When the gas is blown out of the bottom opening 13 from the top opening 12, the rotating shaft 11 will be driven to rotate through the blades 111.

[0038] The mouth pad 2 is installed on the outer side of the top opening 12 and is used to cushion the mouth of the trainee so that the trainee can blow the exhaled gas into the chamber body 1 when exhaling.

[0039] See also Figure 1 and Figure 5 The long column 3 is installed on one side of the warehouse body 1, and a sliding groove 31 is provided on one side of the long column 3. An indicating column 32 is slidably installed in the sliding groove 31 along the length direction of the long column 3. A scale window 33 is provided on one side of the sliding groove 31, and the moving position of the indicating column 32 can be observed through the scale window 33. Scale lines 34 are arranged outside the scale window 33 along the length direction of the long column 3, and the scale lines 34 have a zero point.

[0040] The driving mechanism 4 is drivingly connected to the rotating shaft 11 and the indicating column 32 respectively, and can drive the indicating column 32 to move synchronously when the rotating shaft 11 rotates.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, specifically, the driving mechanism 4 includes an outer convex shaft 41, a connecting rod 42, a first ratchet 43, an arc-shaped groove 44 and a transmission shaft 45. The transmission shaft 45 is rotatably installed on the outside of the warehouse body 1 and is respectively provided with a ratchet 451 and a gear 452. The arc-shaped groove 44 is opened on the outer wall of the warehouse body 1 and surrounds the outside of the ratchet 451. The arc center of the arc-shaped groove 44 is concentric with the axis of the transmission shaft 45. A slider 441 is slidably installed in the arc-shaped groove 44. The first ratchet 43 is provided with a slider 441. The pawl 43 is rotatably mounted on the slider 441 and is provided with a torsion spring, which can provide elastic force so that the first pawl 43 can press against the tooth surface of the ratchet 451. The outer convex shaft 41 is coaxially connected with the rotating shaft 11 and is located outside the chamber body 1. The outer end of the outer convex shaft 41 is eccentrically provided with a support block 411. One end of the connecting rod 42 is rotatably connected with the support block 411 and the other end is connected with the slider 441. The indicator column 32 is provided with a rack 321 meshing with the gear 452. When the rotating shaft 11 rotates, the outer convex shaft 41 will be driven to rotate synchronously, and the slider 441 will be driven to slide back and forth repeatedly in the arc groove 44 through the swing of the support block 411 and the connecting rod 42, thereby driving the first pawl 43 to push the ratchet 451 to rotate through reciprocating movement, and the ratchet 451 drives the gear 452 to rotate through the transmission rotating shaft 45, and the gear 452 drives the indicator column 32 to move through the rack 321. Every time the rotating shaft 11 rotates one circle, the slider 441 can complete a round of back and forth at both ends of the arc groove 44, so that the first pawl 43 can push the ratchet 451 to rotate the same distance after each rotation of the rotating shaft 11, and finally the indicator column 32 can move a fixed distance after each rotation of the rotating shaft 11, thereby improving the accuracy of the displacement of the indicator column 32.

[0042] Preferably, a second pawl 46 is rotatably installed on the outer wall of the warehouse body 1 and located outside the ratchet 451. A torsion spring is installed on the second pawl 46 so that the second pawl 46 can press against the tooth surface of the ratchet 451. The second pawl 46 can prevent the ratchet 451 from rotating in the opposite direction, thereby preventing the ratchet 451 from being pushed back due to the reciprocating movement of the first pawl 43, resulting in inaccurate displacement of the indicator column 32.

[0043] Preferably, a reset groove 35 is provided on one side of the sliding groove 31, and a paddle 322 is installed on the indicator column 32 to slide out of the reset groove 35. After each training, the indicator column 32 can be moved to the zero point position of the scale line 34 by paddle 322 for subsequent training.

[0044] During specific use, the trainee holds the chamber body 1 and puts his mouth toward the mouth pad 2. The trainee blows air into the chamber body 1 at one time. The gas blows the blade 111 on one side of the rotating shaft 11 to rotate the rotating shaft 11, and the indicator column 32 is driven to move synchronously through the driving mechanism 4. After blowing, the position of the indicator column 32 can be checked through the scale window 33, and the training result can be checked through the position of the indicator column 32 on the scale line 34.

[0045] The present invention utilizes the trainee's blowing to drive the rotating shaft 11 to rotate, and converts the number of rotations of the rotating shaft 11 into the linear movement of the indicator column 32 through the driving mechanism 4, and converts the amount of gas blown by the trainee into a more intuitive movement of the indicator column 32 through a series of transmissions, so that each training result is clearer and more intuitive, which is convenient for recording and is conducive to improving the accuracy of the respiratory volume data.

[0046] like Figure 4 As shown, in one embodiment, an adjusting block 14 is installed on the outer wall of the warehouse body 1, and an adjusting stud 15 is screwed on the adjusting block 14, and the adjusting stud 15 is arranged along the radial direction of the outer convex shaft 41, and a friction head 151 is arranged on the end of the adjusting stud 15 facing the outer convex shaft 41. The friction head 151 can be a rubber head. By rotating the adjusting stud 15, the pressure of the friction head 151 on the side of the adjusting block 14 can be changed, and then the rotational resistance of the rotating shaft 11 can be adjusted, so that the training intensity can be changed according to the situation of the trainee, and the training effect is improved.

[0047] like Figure 2 and Figure 3 As shown, in one embodiment, a connecting ring 121 is provided on the outer side of the top opening 12, the mouth pad 2 is in the shape of a trumpet with an expanded top, and an inserting tube 21 which can be movably inserted into the inner side of the connecting ring 121 is provided at the bottom thereof. The mouth pad 2 is detachably connected to the top opening 12 by inserting the inserting tube 21 into the connecting ring 121. After each training, the used mouth pad 2 can be removed and replaced with a new mouth pad 2 during the next training, making the training process more hygienic and safer.

[0048] like Figure 1-Figure 5As shown, further, it also includes a disassembly mechanism 5, which includes a cylinder 51, a connecting pipe 52 and a ring magazine 53. The cylinder 51 is installed at one end of the long column 3 close to the zero point of the scale line 34. A piston column 511 parallel to the long column 3 is slidably installed in the cylinder 51, and one end of the piston column 511 slides into the sliding groove 31. The ring magazine 53 is surrounded and arranged on the outside of the connecting ring 121. The ring magazine 53 has an annular internal space, and a plurality of through holes 531 are opened on the top of the ring magazine 53. A piston ring piece 532 is slidably installed in the ring magazine 53, and a plurality of top columns 533 penetrating the through holes 531 are arranged on the top of the piston ring piece 532. One end of the connecting pipe 52 is connected with the cylinder 51 and the other end is connected with the ring magazine 53. After each training session, the indicator column 32 is moved below the zero reading of the scale line 34 so as to record the reading next time. When the indicator column 32 moves to the end of the sliding groove 31 close to the zero reading of the scale line 34, the indicator column 32 presses the piston column 511 into the cylinder 51 and transmits the air pressure to the ring chamber 53 through the connecting pipe 52, so that the piston ring piece 532 is pushed upward by the air pressure and the mouth pad 2 is pushed away from the top opening 12 through the push column 533, so that when the indicator column 32 is pushed back, the used mouth pad 2 is automatically removed, which is helpful to remind the trainee to replace the new mouth pad 2.

[0049] Preferably, a push ring 22 is provided on one side of the mouth pad 2 close to the piston column 511 , and the push ring 22 is directly opposite to the top of the through hole 531 , so that the mouth pad 2 can be pushed smoothly by the push column 533 .

[0050] Furthermore, when the indicator column 32 moves to the end of the sliding groove 31 close to the zero point of the scale line 34, the rack 321 will be disengaged from the gear 452. In this state, the new mouth pad 2 is not installed, the indicator column 32 is disconnected from the driving mechanism 4, and the device cannot record the training results, thereby reminding the trainee to install a new mouth pad 2. After replacing the new mouth pad 2, when the plug-in cylinder 21 is reinserted into the connecting ring 121, the mouth pad 2 can push the top column 533 downward and push the piston ring 532 downward, and transmit the air pressure to the cylinder 51 through the connecting pipe 52 to push the piston column 511 into the sliding groove 31. The piston column 511 will push the indicator column 32 to move so that the rack 321 is re-engaged with the gear 452, and at the same time, the end of the indicator column 32 away from the cylinder 51 can be pushed to align with the zero point of the scale line 34. When the mouth pad 2 is installed on the top opening 12, the air pressure generated by the mouth pad 2 pressing the piston ring sheet 532 can drive the piston column 511 to push the indicator column 32 to move, thereby making the rack 321 engage with the gear 452. After the mouth pad 2 is removed, the trainee can be reminded to replace and use a new mouth pad 2. At the same time, the piston column 511 can also push the indicator column 32 to align with the zero point of the scale line 34 after the mouth pad 2 is installed, which is beneficial to improving the calibration efficiency of the device and saving the preparation time before training.
