Detailed Description

The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings, in which reference is made to the accompanying drawings, wherein like reference numerals refer to like elements throughout.

Embodiment 1, this embodiment provides a singing breath exercise device, as shown in fig. 1, which includes an exercise barrel 1, a blowing pipe 2 is connected to the bottom of the exercise barrel 1, so that a singer can blow air into the exercise barrel 1 through the blowing pipe 2 during exercise, and is characterized in that, as shown in fig. 4, a fan blade 4 is coaxially and rotatably installed in the exercise barrel 1, two magnets 3 are transversely arranged at an interval on the upper end surface of the exercise barrel 1 (when two magnets 3 are arranged, N-level and S-level of the two magnets 3 are oppositely arranged, i.e. a closed magnetic field is formed), as shown in fig. 4, a conductive frame 5 which coaxially rotates with the fan blade 4 is arranged between the two magnets 3, and the upper end of the conductive frame 5 is connected with a current detection device, when the singer blows air through the blowing pipe 2, air flows into the exercise barrel 1 and rotates the fan blade 4, at this time, the fan blades 4 rotate to synchronously drive the conductive frame 5 to rotate, and as the conductive frame 5 is arranged in the closed magnetic field formed by the two magnets 3, the conductive frame 5 is further caused to perform magnetic induction line cutting motion in the closed magnetic field, at this time, an induced current is generated in the conductive frame 5, and the value of the corresponding induced current can be detected by the current detection device, of course, the value of the induced current generated is larger when the rotation speed of the conductive frame 5 is higher, and is smaller when the rotation speed of the conductive frame is lower (the value of the induced current is kept constant, which indicates that the blowing rate of the singer is more stable at this time);

referring to fig. 4, a support bracket 6 rotating coaxially with the fan blade 4 is arranged in the practice barrel 1 (the support bracket 6 is coaxially sleeved on the shaft of the fan blade 4 and the support bracket 6 is in a cross shape, as shown in fig. 5), in an initial state, that is, when a singer does not blow air or performs stable lung breathing practice under a small breath force, a plurality of connecting rods 7 slidably mounted on the support bracket 6 along the radial direction of the practice barrel 1 are not in contact with the rotating ring 9, that is, the rotating speed of the fan blade 4 is low at the moment, the generated centrifugal force is low, the connecting rods 7 cannot move along the support bracket 6 along the radial direction close to the rotating ring 9 against the elastic force of the return spring 8, the rotating ring 9 does not rotate at the moment, and the singer performs stable lung breathing practice under a small breath force, at the moment, the singer only needs to blow air at a relatively stable breath rate under a relatively small breath force, the fan blades 4 are further driven to rotate at a slower and stable rotating speed, so that the conductive frame 5 which rotates coaxially with the fan blades 4 performs cutting magnetic induction line motion in a closed magnetic field formed by the two magnets 3 (at the moment, induced current generated in the conductive frame 5 is small), the change of the numerical value of the induced current is detected in real time through the current detection device, and then lung breathing exercise can be reflected that a singer can not perform lung breathing exercise at a stable breathing rate under a small breathing force (the singer can also adjust the breathing rate in real time according to the fluctuation of the observed current numerical value and make the breathing rate stable, and the effect of performing the stable lung breathing exercise under the small breathing force is realized);

when a singer needs to do lung breathing exercise at a relatively stable breathing rate under a relatively large breath force, the singer only needs to increase the air blowing rate per unit time, and then drive the fan blades 4 to rotate at a relatively large rotating speed, at this time, the fan blades 4 drive the support bracket 6 to synchronously rotate at a relatively large rotating speed, at this time, the generated centripetal force is relatively large, and the connecting rods 7 overcome the elastic force of the return springs 8 and move along the support bracket 6 towards the direction close to the rotating ring 9, so that finally the connecting rods 7 enter the rotating ring 9 and are positioned by the positioning device arranged in the rotating ring 9, at this time, the connecting rods 7 are connected with the rotating ring 9 and the rotating ring 9 is driven to rotate synchronously along with the fan blades 4, and referring to fig. 14, an inner gear ring 10 is coaxially and rotatably arranged in the exercise barrel 1, and a part of the inner gear ring 10 with teeth is arranged in the rotating ring 9 (as shown in fig. 19) Shown in the figure), the part without teeth of the inner gear ring 10 is arranged outside the rotating ring 9 and is rotatably installed in the exercise barrel 1 (as shown in figure 4, and friction damping pads are installed at the upper end and the lower end of the inner gear ring 10 outside the rotating ring 9 for increasing the friction resistance of the part where the inner gear ring 10 is rotatably matched with the exercise barrel 1), when the singer increases the blowing rate in unit time, the rotating ring 9 is synchronously driven to rotate by the fan blades 4 and the rotating ring 9 drives the unlocking gear 11 to rotate, because the unlocking gear 11 is meshed with the inner gear ring 10, the unlocking gear 11 is further driven to rotate by the meshing of the inner gear ring 10 and the unlocking gear 11 along with the rotation of the rotating ring 9 (at this time, the meshing interaction force between the unlocking gear 11 and the inner gear ring 10 is smaller than the friction resistance of the part where the friction damping pads fixed on the inner gear, because the unlocking gear 11 does not touch the limiting mechanism, the inner gear ring 10 does not rotate, the unlocking gear 11 drives the energy storage withdrawing device connected with the unlocking gear 11 to store energy all the time along with the continuous rotation of the rotating ring 9 when the unlocking gear 11 touches the limiting mechanism (before the unlocking gear 11 touches the limiting mechanism, the unlocking gear 11 does not rotate relative to the rotating ring 9 and the energy storage withdrawing device does not store energy any more), at the moment, the unlocking gear 11 cannot rotate relative to the rotating ring 9 due to the limitation of the limiting mechanism, at the moment, the rotating ring 9 drives the inner gear ring 10 to rotate in the exercise cylinder 1 through the unlocking gear 11 and the inner gear ring 10 which are meshed together, at the moment, the lung breathing exercise under the large expiratory force (the fan blades 4 are driven to rotate by blowing to drive the rotating ring 9), The inner gear ring 10 rotates, the friction damping pad is arranged on the inner gear ring 10, so that the friction resistance during rotation can be increased, a singer can drive the inner gear ring 10 to rotate only with a large expiratory force, the singer can control the blowing rate of the singer by the fluctuation of the value of the induced current detected by the current detection device, the value of the induced current is stabilized in a range, and the effect of performing lung breathing exercise at a stable blowing rate under a large expiratory force can be realized;

when the inner gear ring 10 rotates, the timing device starts timing, and when the exercise time of the singer reaches the set time, the timing device drives the disengaging gear 14 to rotate through the transmission device connected with the timing device and drives the disengaging device through the disengaging gear 14, so that the inner gear ring 10 is disengaged from the unlocking gear 11 (when the unlocking gear 11 is disengaged from the inner gear ring 10, a larger load is reduced, the singer still blows at the previous breath force, the rotating speed of the rotating ring 9 is rapidly increased, the rotating speed of the fan blades 4 is synchronously increased, the current value detected by the current detection device is obviously increased, the exercise time is reached, the air blowing exercise can be stopped in the process), when the inner gear ring 10 is disengaged from the unlocking gear 11, the positioning device is released from the connecting rod 7 under the action of the energy storage withdrawing device, and the connecting rod 7 is withdrawn from the rotating ring 9 outwards, at the moment, the singer completes the lung breathing exercise at a relatively stable breathing rate under a relatively large breathing force.

Embodiment 2, on the basis of embodiment 1, referring to fig. 5, one end of the connecting rod 7 near the rotating ring 9 is integrally provided with a transition rod 15 with a width smaller than that of the connecting rod 7, and the transition rod 15 is provided with an arc-shaped plate 16 facing one side of the rotating ring (the width of the arc-shaped plate 16 is the same as that of the connecting rod 7), referring to fig. 13, we are provided with an insertion hole 17 corresponding to the arc-shaped plate 16 on the inner circular surface of the rotating ring 9 (we make the width of the insertion hole 17 be the same as that of the connecting rod 7), referring to fig. 14, the positioning device includes: arc-shaped positioning blocks 18 which are arranged at two sides of the insertion hole 17 and are slidably arranged in the rotating ring 9 along the direction vertical to the insertion hole 17, when the two arc-shaped positioning blocks 18 are arranged, the arc-shaped surfaces of the two arc-shaped positioning blocks face one side of the connecting rod 7, when the connecting rod 7 does not enter the rotating ring 9, the two arc-shaped positioning blocks 18 are abutted with each other under the action of a positioning spring 19, when the blowing strength of a singer is increased, the fan blade 4 is driven to rotate at a higher rotating speed and generate a higher centrifugal force, so that the connecting rod 7 overcomes the elastic force of the return spring 8 and moves towards the direction close to the insertion hole 17 under the action of the centrifugal force, when the arc-shaped plate 16 enters the insertion hole 17 and the arc-shaped surfaces of the two arc-shaped positioning blocks 18 contact with the arc-shaped surfaces of the two arc-shaped positioning blocks 18, the two arc-shaped, with the further forward advancement of the connecting rod 7 so that when the side of the arcuate plate 16 facing the corresponding connecting rod 7 is aligned with the planar portions of the two arcuate locating blocks 18, at this time, the two arc-shaped positioning blocks 18 move towards the direction of approaching each other under the action of the positioning spring 19 and finally abut against the side wall of the transition rod 15, as shown in fig. 15, in which the positioning effect of the connecting rod 7 is achieved, we can provide a stop (not shown) in the rotating ring 9, so that when the connecting rod 7 is brought under centrifugal force into the turn ring 9 and in the positioned position as shown in figure 15, the singer will not move further along the radial direction of the rotating ring 9 due to the increased blowing force, i.e. so that the foremost end of the arcuate plate 16 abuts against the stop for limiting the same when the arcuate plate 16 is in the position shown in figure 15.

Embodiment 3, on the basis of embodiment 2, referring to fig. 19, the unlocking gear 11 drives a one-way half gear coaxially arranged with the unlocking gear 11, the one-way half gear is rotatably installed on the unlocking gear 11 shaft (we rotatably install pawls 68 on the unlocking gear 11 shaft and a plurality of ratchets 67 matched with the pawls 68 are arranged on the inner circumferential surface of the one-way half gear at intervals, we fix elastic blocks 69 abutting against the pawls 68 on the unlocking gear 11 shaft for resetting the pawls 68), referring to fig. 13, the energy storage withdrawing device comprises a coil spring 21 connected with the unlocking gear 11 shaft, the other end of the coil spring 21 is connected with the inner wall of a rotating ring 9, and we set the fan blade 4 such that when a singer blows into the exercise barrel 1 through the blowing pipe 2, the rotating ring 9 is driven to rotate in the clockwise direction as shown in fig. 13 by the fan blade 4, when the unlocking gear 11 does not touch the limiting mechanism, the unlocking gear 11 is enabled to rotate along the anticlockwise direction shown in the attached drawing 13 through the inner gear ring 10 meshed with the unlocking gear 11 and along with the rotation of the rotating ring 9, at this time, the shaft of the unlocking gear 11 cannot drive the one-way half gear to rotate (at this time, the one-way half gear and the shaft of the unlocking gear 11 generate relative rotation as shown in the attached drawing 19), and along with the rotation of the unlocking gear 11 along the anticlockwise direction shown in the attached drawing 13, the coil spring 21 is enabled to contract and store energy, so that when the unlocking gear 11 touches the limiting mechanism, the unlocking gear 11 does not rotate relative to the rotating ring 9 any more, and at this time, the rotating ring 9 is meshed with the inner gear ring 10 through the unlocking gear 11 to drive the inner gear ring 10 to rotate;

referring to fig. 19 (in this case, the initial position state of the position-limiting post and the position-limiting baffle 13), the position-limiting mechanism includes a position-limiting post fixedly installed on the lower end surface of the unlocking gear 11 and a position-limiting baffle 13 fixed on the bottom wall of the rotating ring 9 and matching with the position-limiting post, when the unlocking gear 11 is rotated in the counterclockwise direction as shown in fig. 13, so that the limit post touches the limit stop 13, that is, when the limit post fixedly installed on the lower end surface of the unlocking gear 11 is rotated from the position shown in fig. 19 to the position on the other side of the limit stop 13, at this time, the unlocking gear 11 cannot be rotated further with respect to the rotating ring 9 (the coil spring 21 stops storing energy), at the moment, the rotating ring 9 drives the inner gear ring 10 to rotate through the unlocking gear 11 and the inner gear ring 10 which are meshed together, and then the lung breathing exercise operation is started at a relatively stable breathing rate under a relatively large breathing force;

referring to fig. 13, initially, the U-shaped rack 22 is in the position shown in fig. 13 under the action of the withdrawing spring 23, when the exercise time reaches the corresponding set time in the process, the disengaging gear 14 is driven to rotate by the transmission device under the action of the timing device so as to drive the disengaging device to disengage the internal gear ring 10 from the unlocking gear 11, when the internal gear ring 10 is disengaged from the unlocking gear 11 (as the load is removed, the singer observes that the induced current is obviously increased through the current detection device, then the blowing exercise is stopped, and the connecting rods 7 are no longer subjected to the centrifugal force), at this time, the coil spring 21 drives the shaft of the unlocking gear 11 to rotate in the clockwise direction as shown in fig. 13, so as to drive the one-way half gear to rotate in the clockwise direction as shown in fig. 13 and enable the one-way half gear to start to be engaged with the teeth on a cantilever of the U-shaped rack 22 fixedly provided with the withdrawing arc-shaped plate, at this time, the one-way half gear drives the U-shaped rack 22 to move towards the direction close to the connecting rod 7 and the withdrawing spring 23 is compressed, as shown in fig. 15, along with the continuous movement of the U-shaped rack 22, so that when the arc withdrawing plate 24 touches the withdrawing rod 25 slidably installed in the arc plate 16 (initially, a part of the withdrawing rod 25 is placed outside the arc plate 16, as shown in fig. 6), the withdrawing rod 25 is synchronously moved towards the direction contracting into the arc plate 16, as shown in fig. 6, so that when the withdrawing rod 25 is completely contracted into the arc plate 16 under the action of the arc withdrawing plate 24 (at this time, the telescopic spring 26 connected between the withdrawing rod 25 and the arc plate 16 is compressed), we set the withdrawing rod 25 at one end of the arc plate 16 to perform chamfering setting, and therefore along with the process of contracting the withdrawing rod 25 into the arc plate 16, the chamfered end of the withdrawing rod 25 abuts against a convex plate 29 fixedly connected with the two squeezing blocks 27 and enables the two squeezing blocks 27 to move in the transition rod 15 towards the direction away from each other (initially, the two squeezing blocks 27 are positioned in the transition rod 15 and the two squeezing blocks 27 are vertically arranged at intervals in the transition rod 15), so that when the withdrawing rod 25 is completely contracted into the arc-shaped plate 16 under the action of the arc-shaped withdrawing plate 24, the two squeezing blocks 27 slide out for the maximum distance, and the two arc-shaped positioning blocks 18 abutting against the wall of the transition rod 15 are forced to move towards the direction away from each other along with the outward sliding out of the squeezing blocks 27, and the squeezing blocks 27 are set to enable the arc-shaped positioning blocks 18 to move to the position where the arc-shaped plate 16 is not hindered from being withdrawn outwards when the squeezing blocks 27 slide out for the maximum distance (at the moment, the opposite sides of the two arc-shaped positioning blocks 18 are respectively kept flush with the two, with the continuous movement of the U-shaped rack 22, the arc-shaped plate 16 (the connecting rod 7) is driven to outwardly withdraw from the rotating ring 9 through the arc-shaped withdrawing half, and it is set that after the arc-shaped surface of the arc-shaped plate 16 passes over the two arc-shaped positioning blocks 18, the U-shaped rack 22 moves to the farthest distance (the coil spring 21 cannot continuously drive the U-shaped rack 22 to move, at this time, the one-way half gear just needs to be separated from the teeth on the cantilever on the side, where the arc-shaped withdrawing plate 24 is fixed to the U-shaped rack 22, and needs to be meshed with the teeth on the other cantilever of the U-shaped rack 22), and at this time, the connecting rod 7 moves out of the insertion hole 17;

after the U-shaped rack 22 moves to the farthest distance under the action of the coil spring 21, at this time, the U-shaped rack 22 moves in the opposite direction under the action of the withdrawing spring 23 and drives the one-way half gear to idle by the teeth on the other cantilever of the U-shaped rack 22, and at this time, the rotation of the one-way half gear does not drive the shaft of the unlocking gear 11 to rotate, so that the U-shaped rack 22 moves to the initial position under the action of the withdrawing spring 23;

when the arc-shaped withdrawing plate 24 is not abutted to the withdrawing rod 25 any more, the withdrawing rod 25 slides outwards out of the arc-shaped plate 16 under the action of the telescopic spring 26 and the two extrusion blocks 27 synchronously contract into the transition rod 15 under the action of the extrusion spring 28, so that the resetting effect is realized.

in the scheme, the timing device is introduced, so that a singer can judge whether to perform lung breathing exercise with stable expiratory strength only by the fluctuation change of the numerical value of the induced current detected by the current detection device, and when the time for performing lung breathing exercise with stable expiratory rate under the large expiratory strength reaches the set exercise time, the judgment is also performed only by the fluctuation of the numerical value of the induced current detected by the current detection device (the singer does not need to acquire the exercise time by observing a timer), so that the singer can perform lung breathing exercise more intensively with stable respiratory rate, and the singer can perform the exercise more intensively while ensuring higher exercise efficiency;

referring to fig. 3, we install an additional ring 66 coaxially and rotatably in the practice cylinder 1 above the rotating ring 9 (we can also install a friction damping pad at the position where the additional ring 66 is rotatably matched with the practice cylinder 1 to increase the friction resistance), and the additional ring 66 is matched with an adjusting screw 65 through threads (we fix a threaded cylinder 64 matched with the adjusting screw 65 on the rotating ring 9), we can correspondingly select the practice intensity of the maximum expiratory force according to the different conditions of singers, that is, the adjusting screw 65 is screwed to be in threaded fit with the rotating ring 9 (i.e., the rotating ring 9 is connected with the additional ring 66), when a singer blows air and drives the rotating ring 9 to rotate, the additional ring 66 is synchronously driven to rotate, and at this time, the singer has to blow air with a larger expiratory force, the square can drive and rotate ring 9 and additional ring 66 synchronous rotation and make the induced-current that current detection device detected out maintain a numerical value size within range, we link together additional ring 66 and ring 9 through revolving to twist adjusting screw 65 and then decide, consequently make singer practise under the biggest expiration dynamics of difference, make the suitability of the device improve greatly, in this scheme, the material of exercise section of thick bamboo 1 we select the processing of transparent plastic material to form and other transmission and the rotating part that use in this scheme all select the processing of the material that the material is lighter to form.

The exercise device can enable a singer to realize lung breathing exercise at a stable breathing rate under different breathing dynamics, and when the singer switches from a small breathing dynamics exercise mode to a large breathing dynamics exercise mode, the lung breathing exercise can be realized only by improving the blowing rate in unit time without excessive manual operation;

when the exercise mode is switched to the exercise mode with the large expiratory force, the timing device is started and can monitor that the singer completes the exercise of lung breathing at the stable expiratory rate under the large expiratory force within the specified time, and after the singer completes the exercise of the large expiratory force within the specified time (at the moment, the singer stops blowing air), under the action of the timing device, the exercise mode of the exercise device is switched to the exercise mode with the small expiratory force again from the exercise mode with the large expiratory force, and the whole switching process does not need manual extra participation, so that the singer can more concentrate on the exercise of lung breathing;

in this scheme, we still are provided with in exercise section of thick bamboo 1 and rotate circle 9 matched with supplementary ring, and we can set up according to different singers 'exercise demand for the supplementary ring is connected (can further improve the singer and breathe the exercise in the lung under the biggest expiratory dynamics when connecting together) or breaks away from (singer's the biggest expiratory dynamics of practicing this moment is less than the exercise intensity that supplementary ring and rotation circle 9 link together).
