Here, it goes without saying that the respiration control device100may be coupled to the second tube33in the embodiment.

Hereinafter, the respiration control device100will be described in detail.

Referring toFIG.3, the respiration control device100may include a body part200and a pressure controller300.

The body part200is detachably coupled to the mouthpiece30, and when a user directly puts his or her mouth on the respiration control device100to breathe in and out, air by user's respiration may flow into the mouthpiece30through an internal flow path203(refer toFIG.4).

In detail, the body part200may have an inflow part201formed on one side on which a user puts his or her mouth and configured to allow air by user's respiration to flow thereinto, an outflow part202formed on the other side coupled to the mouthpiece30and configured to allow the air flowing thereinto to flow out therethrough, and the internal flow path203formed therein and configured to allow the inflow part201and the outflow part202to communicate with each other.

Here, the inflow part201communicates with an inlet part212of a control room210, and as shown in the drawing, the same may be configured to form a long and narrow flow path corresponding to the size of the user's mouth. In the drawing, the inflow part201is formed in a square duct tube shape to correspond to the shape and size of the user's mouth, so that the user may more easily breathe in and out while holding the inflow part201in the mouth. However, the above-described shape of the inflow part201is a preferred embodiment, and it goes without saying that the inflow part201may be formed in various shapes such as an elliptical tube shape in addition to the square duct tube shape.

The body part200has the pressure controller300formed on the internal flow path203, and the control room210formed therein and configured to control pressure of air flowing by the operation of the pressure controller300.

The body part200may include a partition wall211formed therein and configured to support a moving member310and to form the control room210.

In the drawing, the partition wall211includes a lower wall with a plate shape disposed in the horizontal direction corresponding to the movement direction of the moving member310and located below the moving member310to support the moving member310upwards, the lower wall having the outlet part213formed thereon, a side wall located on the side of the moving member310and configured to guide the moving member310, and a rear wall built behind the moving member310.

Here, the partition wall211may be formed to limit rearward movement of the moving member310through the rear wall so as to limit sliding movement of the moving member310, and to limit forward movement of the moving member310by a locking jaw formed by causing the front end of the lower wall to be located lower than the upper surface of the inflow part201.

Meanwhile, the moving member310may adjust an air passage cross-sectional area of each of the inlet part212and the outlet part213by movement thereof in the control room210, and through this movement, pressure of flowing air is controlled. Here, pressure control in the control room210will be described in more detail in the operation of the pressure controller300inFIG.4to be described later.

Hereinafter, the pressure controller300will be described.

The pressure controller300is provided in the control room210on the internal flow path203, and the same is operated by user's operation to perform a function of controlling pressure of air flowing through the internal flow path203.

Specifically, the pressure controller300may include the moving member310, a driving part320, and a rotation lever330.

First, the moving member310is provided on the internal flow path203and moves forwards and rearwards. Further, the moving member310may be configured to adjust an air passage area of the internal flow path203by movement thereof, thereby controlling air pressure.

In detail, the moving member310is installed in the control room210and the surface thereof slides along the side surface of the partition wall211. Further, the moving member310may be configured to adjust, by movement thereof, an air passage cross-sectional area of each of the inlet part212and the outlet part213of the control room210.

In the drawings, a description has been given as to a case in which the moving member310is formed in a substantially cylindrical shape, and the upper and lower outer circumferential side surfaces thereof are formed to slide along the partition wall211, but the present invention is not limited to the case.

Meanwhile, the moving member310may have a guide protrusion formed on the lower outer circumferential side surface thereof in the axial direction and inserted into a sliding groove formed on an lower wall of the partition wall211so as to slide along the sliding groove.

In addition, the moving member310may have a plurality of moving grooves311continuously formed on the upper outer circumferential side surface thereof in the movement direction, that is, in the axial direction. Here, the moving grooves311are coupled to the driving part320to allow the moving member310to be moved by rotation of the driving part320.

The moving member310may have a guide portion312formed on the outer surface thereof and configured to move along a fitting portion of the partition wall211to be described later. Here, one or more guide portions312may be formed in the axial (length) direction from one end of the outer surface of the moving member310to the other end thereof.

As shown in the drawing, the guide portion312may have a guide protrusion312aformed thereon and a guide groove312bformed therein. The guide protrusion312aand the guide groove312bmay be formed to be spaced apart from each other on the outer circumferential side surface of the moving member310in the circumferential direction.

Meanwhile, the partition wall211facing the moving member310has fitting portions formed at positions respectively corresponding to the guide protrusion312aand the guide groove312b, so that the guide protrusion312aand the guide groove312bare respectively fitted to the fitting portions and coupled thereto, thereby performing guidance of the moving member310. As shown in the drawing, regarding the fitting portions, the side wall of the partition wall211may be formed in a rib shape so as to be fitted into the guide groove312b, and the partition wall211may have a fitting groove formed in the lower wall thereof and configured to allow the guide protrusion312ato be fitted thereinto.

The driving part320is rotatably installed in the body part200, and the same is coupled to the moving member310to enable the moving member310to reciprocate in a straight line by rotation thereof.

Specifically, the driving part320may include a rotation shaft322and a driving gear321.

The rotation shaft322may be axially coupled to the rotation lever330to rotate in conjunction with rotation of the rotation lever330.

The driving gear321is axially coupled to the rotation shaft322and rotates in conjunction with rotation of the rotation shaft322, and the same has a screw thread formed on the outer circumferential surface thereof and engaged with the moving groove311, thereby allowing the moving member310to reciprocate according to rotation of the driving gear321.

The rotation lever330is provided on the outside of the body part200and is rotated by user's operation. Further, the rotation lever330is axially coupled to the rotation shaft322of the driving part320. Accordingly, when a user operates the rotation lever330to rotate the same, the rotation shaft322may be rotated in conjunction with rotation of the rotation lever330.

Hereinafter, the operation of the respiration control device100according to the operation of the pressure controller300will be described with reference toFIG.4.

First,FIG.4(a)shows a case in which respiration pressure is maximum,FIG.4(b)shows a case in which respiration pressure is medium, andFIG.4(c)shows a case in which respiration pressure is minimum.

First, referring toFIG.4(a), the moving member310of the pressure controller300is moved as close as possible to the inlet part212(right side in the drawing). Accordingly, the inlet part212and the outlet part213are shielded by the moving member310of the pressure controller300so that respiration pressure is maximized.

Next, referring toFIG.4(b), when a user operates the rotation lever330of the pressure controller300to rotate the driving part320, as shown in the drawing, the moving member310is moved (left side in the drawing) to be spaced apart from the inlet part212by a predetermined distance. In this case, the inlet part212and the outlet part213are partially opened by the pressure controller300, and an air passage area is increased as compared with the case inFIG.4(a), which results in lower respiration pressure.

Finally, referring toFIG.4(c), when a user additionally operates the rotation lever330of the pressure controller300to further rotate the driving part320, as shown in the drawing, the moving member310is moved (left side in the drawing) to be maximally spaced apart from the inlet part212. In this case, both the inlet part212and the outlet part213are opened by the pressure controller300, and an air passage area is maximized, which results in minimum respiration pressure. Accordingly, a user may breathe most comfortably.

According to the above description, in the pressure controller300, when air is introduced from the inlet part212at the front end in the movement direction of the moving member310, the introduced air flows out through the outlet part213formed on the side of the moving member310, and an air passage area of each of the inlet part212and the outlet part213may be adjusted by movement of the moving member310, thereby controlling respiration pressure. That is, in the pressure controller300of the present invention, a user may freely and directly control respiration pressure by rotating the rotation lever330depending on the health state of the user, thereby making it possible not only to provide respiration exercise suitable for the individual health state, but also to increase an effect of respiration exercise.

Meanwhile, the pressure controller300may further include a recognition means340provided on the body part200and configured to allow a user to recognize whether the pressure controller300operates.

Referring toFIG.5, the recognition means340may include a vibration ball341and a support spring342. Here, the rotation shaft323may have a locking groove323aformed on a side surface thereof in contact with the recognition means340. The locking groove323ais spaced apart from the axis center of the rotation shaft323by a predetermined distance in the radial direction. Further, one or more locking grooves323aare radially disposed at a predetermined angle in the circumferential direction of the rotation shaft323, and the same rotate around the axis center of the rotation shaft323when the rotation shaft323rotates.

In this case, the vibration ball341is in contact with the side surface of the rotation shaft323corresponding to the position of the locking groove323a. When the rotation shaft323rotates, the vibration ball341moves and vibrates back and forth depending on the position of the locking groove323a. By such vibration, a user may recognize whether the driving gear321operates.

FIGS.5(a) and5(b)show movement of the vibration ball341according to rotation of the rotation shaft323.FIG.5(a)shows a case in which the vibration ball341is moved to the right by the locking groove323a, andFIG.5(b)shows a case in which the vibration ball341comes into contact with the flat side surface of the rotation shaft323and is moved to the left.

The support spring342serves to elastically support the vibration ball341toward the rotation shaft323so that the vibration ball341comes into close contact with the rotation shaft323.

Meanwhile, the recognition means340may be applied to a known ball plunger, but is not limited thereto. Furthermore, this recognition means340includes the vibration ball341and the support spring342, and is configured using the user's touch. In addition to this configuration, it goes without saying that various configurations such as a scale using user's vision are applicable as long as the above-mentioned recognition purpose is achievable.

The recognition means340is a means configured to allow a user to recognize a degree of rotation of the rotation lever330by himself or herself when the user rotates the rotation lever330, and the user may recognize rotation of the rotation lever330and a degree of pressure control by vibration of the vibration ball341.

FIGS.6to8are views showing a respiration control device100aaccording to another embodiment of the present invention, and the respiration control device100aaccording to another embodiment of the present invention will be described in detail with reference to the drawings.

First, referring toFIG.6, the respiration control device100aaccording to another embodiment of the present invention may include a body part200aand a pressure controller400.

The body part200ais detachably coupled to the above-described mouthpiece30, and when a user directly puts his or her mouth on the respiration control device100ato breathe in and out, air by user's respiration may flow into the mouthpiece30through an internal flow path.

Referring toFIG.7, the body part200amay have an inflow part201formed on one side and configured to allow air by user's respiration to flow thereinto, an outflow part202formed on the other side to be coupled to the mouthpiece30and configured to allow the air flowing thereinto to flow out therethrough, and a partition wall211aformed therein, the partition wall211ahaving an inlet part212aformed to penetrate the same.

The body part200amay be formed with a fitting portion220having the pressure controller400coupled thereto. In the drawing, the body part200ais divided by the fitting portion220. When the pressure controller400is coupled to the fitting portion220, each of the divided body parts may be coupled to the front and rear surfaces of the pressure controller400, respectively. In other words, the body part200ais configured to be divided into a first body part and a second body part by the fitting portion220. The first body part may be coupled to the front surface of the pressure controller400, and the second body part may be coupled to the rear surface of the pressure controller400.

The pressure controller400may be coupled to the body part200a, and the same may include a rotation member410, a rotation shaft420, and an operation part430.

The rotation member410is axially coupled to the rotation shaft420in a disk shape and is rotatably installed in the body part200a. Further, the rotation member410may have a plurality of pressure control holes411formed to pass therethrough and spaced apart from each other in the circumferential direction around the rotation shaft420. Here, the pressure control holes411communicate with the inlet part212aof the partition wall211awhen the rotation member410rotates, and the same allow air introduced from the inlet part212ato flow into the mouthpiece30while passing therethrough.

Meanwhile, the pressure control holes411are respectively formed to have different air flow passage areas, and as such pressure of flowing air is controlled by an air passage cross-sectional area of each of the air flow passage areas. In the drawing, the pressure control holes411are formed of four different air passage cross-sectional areas so as to control respiration pressure. Here, as the air passage cross-sectional area increases, respiration pressure decreases. The operation part430may be provided on the outer circumferential surface of the rotation member410and exposed to the outside of the body part200a. Accordingly, a user operates the operation part430to rotate the rotation member410around the rotation shaft. As shown in the drawing, the operation part430may have a plurality of protrusions formed thereon and configured to improve the user's grip and facilitate user's operation, but is not limited thereto.

According to the above description, in the pressure controller400, when a user rotates the rotation member410through the operation part430, pressure is controlled while any one of the pressure control holes411having different passage cross-sectional areas communicates with the inlet part212a.

Hereinafter, the operation of the respiration control device100aaccording to the operation of the pressure controller400will be described.

Referring toFIG.8, the pressure control holes411are formed to have different air passage cross-sectional areas as shown in the drawing, and the pressure controller400may control respiration pressure according to the air passage cross-sectional area of any one of the pressure control holes411communicating with the inlet part212a.

In detail, first,FIG.8(a)shows a case in which the air passage cross-sectional area of the pressure control hole411communicating with the inlet part212ais the largest, and respiration pressure is the lowest. Next,FIG.8(b)shows a case in which the rotation member410is rotated by user's operation, and the pressure control hole411communicating with the inlet part212ahas a smaller air passage cross-sectional area than that ofFIG.8(a). In this case, respiration pressure may be higher than that ofFIG.8(a). Next,FIG.8(c)shows a case in which the rotation member410is rotated by user's operation, and the pressure control hole411communicating with the inlet part212ahas a smaller air passage cross-sectional area than that ofFIG.8(b). In this case, respiration pressure may be higher than that ofFIG.8(b). In addition,FIG.8(d)shows a case in which the rotation member410is rotated by user's operation, and the air passage cross-sectional area of the pressure control hole411communicating with the inlet part212ais the smallest. In this case, respiration pressure is the highest.

According to the above description, the pressure controller400is configured so that a user may selectively control respiration pressure by rotating the rotation member410through the operation part430, and respiration pressure may be controlled by varying the size of the air passage cross-sectional area of the pressure control hole411.

FIG.9is a diagram showing the operation of the recognition means340provided in the pressure controller400described above. Referring to the drawing, the recognition means340has substantially the same configuration as that ofFIG.5including the vibration ball341and the support spring342. Therefore, hereinafter, the operation of the recognition means340according to the operation of the pressure controller400will be mainly described.

First, in the pressure controller400, the rotation member410may have a locking groove410aformed on the side surface thereof in contact with the recognition means340and disposed at a position corresponding to the recognition means340. In the drawing, the plurality of locking grooves410aare radially disposed to be spaced apart from each other in the circumferential direction around the rotation shaft, and the same are rotated by rotation of the rotation member410.

FIGS.9(a) and9(b)show movement of the vibration ball341by rotation of the rotation member410. Referring to the drawings,FIG.9(a)shows a case in which the vibration ball is moved to the left in the drawing by the locking groove410a, andFIG.9(b)shows a case in which the vibration ball341is moved to the right by contacting the flat side surface of the rotation member410.

Meanwhile, the respiration control device100may be detachably coupled to the mouthpiece30, thereby forming a mouthpiece assembly according to an embodiment of the present invention. Here, the mouthpiece assembly according to the embodiment of the present invention may include the above-described respiration control device100or100a, and the mouthpiece30, detachably coupled to the main body20including the respiration measurement module21, formed to have an air flow path therein, and coupled to the respiration control device100or100a.

Although the present invention has been described with reference to the embodiments shown in the drawings for illustrative purposes, those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
