Description

Technical Field

[0001] The utility model relates to the technical field of breathing trainers, in particular to a hand-held breathing trainer with adjustable breathing resistance. Background Art

[0002] A breathing trainer is a device for active breathing exercise. It is designed based on the principle of impedance training. By setting a certain resistance, the user needs to overcome this resistance when inhaling, so as to enhance the strength and endurance of the respiratory muscles.

[0003] Researchers found that hand-held breathing trainers have also been designed in the prior art; at the same time, the inventor believes that the following defects often exist: in the process of designing and using a breathing trainer, the adjustment of breathing resistance is a core function, which directly affects the training effect and user experience. When traditional breathing trainers are designed, they often adopt fixed resistance or disassemble and replace resistance plates. Among them, the breathing trainer with fixed resistance obviously limits its scope of application to a certain extent. However, the breathing trainer with detachable and replaceable resistance plates is often cumbersome to disassemble. Therefore, the inconvenient resistance adjustment is its main technical defect. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that there is a disadvantage in the prior art that the breathing resistance cannot be adjusted conveniently. For this reason, we propose a hand-held breathing trainer with adjustable breathing resistance.

[0007] Vent holes are provided on both the first air flow regulating plate and the second air flow regulating plate;

[0008] Limit blocks are installed on the front side and the rear side of the rod wall of the adjusting rod, limit grooves are opened on both sides of the inner groove wall of the adjusting groove, the limit block on the front side of the rod wall of the adjusting rod is embedded and matched with the limit groove on one side of the inner groove wall of the adjusting groove, the limit block on the rear side of the rod wall of the adjusting rod is embedded and matched with the limit groove on the other side of the inner groove wall of the adjusting groove, and a fillet is opened at the edge of the inner part of the limit groove along the sliding-in direction of the limit block of the adjusting rod.

[0009] Preferably, the ventilation holes on the first air flow regulating plate are fan-shaped;

[0010] The vertex of the fan shape of the ventilation hole coincides with the center of the circular first air flow regulating plate. The radius length of the fan shape of the ventilation hole is less than the radius length of the first air flow regulating plate, and the angular radian of the fan shape of the ventilation hole is greater than the angular radian of the connecting pipe where the adjusting groove is located.

[0011] Preferably, an annular side seal is installed inside the connecting pipe;

[0012] The whole of the annular side seal is annular, and the annular side seal includes an outer convex part and a C-shaped groove part arranged on the outer convex part. A main installation groove for installing the outer convex part of the annular side seal is arranged on the inner side wall of the connecting pipe. The C-shaped groove part is used for clamping the edge of the second air flow regulating plate. The edge surface of the second air flow regulating plate is a contact surface that contacts the inner wall of the C-shaped groove part. The contact surface is a smooth curved surface that converges towards both sides. Inside the connecting pipe, a highly efficient annular side seal is specially designed and installed to ensure the tightness and safety of its internal structure.

[0013] Preferably, a breathing timer is installed on one side of the grasping seat. On one side of the grasping seat, a breathing timer is carefully installed to provide the user with an accurate breathing timing function.

[0014] Preferably, arc-shaped grooves are formed on both the front side and the rear side of the rod wall of the grasping seat. In the design of the grasping seat, arc-shaped grooves are carefully crafted on both the front end and the rear end. Such a design not only looks good but also improves the comfort and stability of grasping.

[0015] Preferably, the number of the limiting grooves is four, and the four limiting grooves are evenly distributed on the two side walls of the adjusting groove along a circular track. Four limiting grooves are evenly distributed inside the adjusting groove to ensure stable structure and perfect function.

[0016] Preferably, a mounting plate is installed inside the connecting pipe. Clamping grooves are formed on both sides of the mounting plate.

Detailed Embodiment

[0026] Now, the present utility model will be further described in detail with reference to the drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0027] Embodiment 1

[0028] As Figure 1 - Figure 2 shown, Embodiment 1 of the present utility model provides an adjustable breathing resistance handheld breathing trainer, including a gripping seat 1. A curved tube 2 is installed at the top of the gripping seat 1. A connecting pipe 3 is installed at the front end of the curved tube 2. A contact nozzle 4 is installed at the front end of the connecting pipe 3;

[0029] The first airflow adjustment plate 5 is fixedly connected to the interior of the connecting pipe 3, and the second airflow adjustment plate 6 is rotatably connected to the interior of the connecting pipe 3; Figure 4 and Figure 5 The top wall of the connecting pipe 3 is provided with an adjusting groove 7, and the top of the second airflow adjusting plate 6 is fixedly connected with an adjusting rod 8; the first airflow adjusting plate 5 and the second airflow adjusting plate 6 are both provided with vents 18, and the front and rear sides of the rod wall of the adjusting rod 8 are both installed with limiting blocks 9, and the inside of the adjusting groove 7 is provided with a limiting groove 10, and the inside of the limiting groove 10 is provided with a rounded corner 11;

[0030] The first airflow adjustment plate 5 and the second airflow adjustment plate 6 are both provided with ventilation holes 18; wherein the ventilation holes 18 on the first airflow adjustment plate 5 may be fan-shaped, while the ventilation holes 18 on the second airflow adjustment plate 6 may be fan-shaped through holes opened on the entire plane or may be composed of a plurality of circular holes;

[0031] Limiting blocks 9 are installed on the front and rear sides of the rod wall of the adjusting rod 8, and limiting grooves 10 are provided on both sides of the inner groove wall of the adjusting groove 7. The limiting block 9 at the front side of the rod wall of the adjusting rod 8 is embedded and matched with the limiting groove 10 on one side of the inner groove wall of the adjusting groove 7, and the limiting block 9 at the rear side of the rod wall of the adjusting rod 8 is embedded and matched with the limiting groove 10 on the other side of the inner groove wall of the adjusting groove 7. The inside of the limiting groove 10 is provided with a rounded corner 11 at the edge along the sliding direction of the limiting block 9 of the adjusting rod 8.

[0032] Analyzing the main structure of the above-mentioned handheld breathing trainer with adjustable breathing resistance, it can be known that the handheld breathing trainer with adjustable breathing resistance is mainly composed of basic structures such as a gripping seat 1, a curved tube 2, a connecting tube 3 and a contact nozzle 4; at the same time, the interior of the connecting tube 3 is fixedly connected with a first airflow adjustment plate 5, and the interior of the connecting tube 3 is rotatably connected with a second airflow adjustment plate 6, that is, the second airflow adjustment plate 6 can be installed and sleeved inside the connecting tube 3, and the two can form a rotational matching relationship; and the top of the above-mentioned connecting tube 3 is provided with an adjustment groove 7, and the top of the second airflow adjustment plate 6 is fixedly connected with an adjustment rod 8. The adjustment rod 8 is used to form a certain angle of toggle rotation in the adjustment groove 7, thereby driving the second airflow adjustment plate 6 to rotate relative to the connecting tube 3. The front and rear sides of the rod wall of the adjustment rod 8 are both installed with limit blocks 9. Specifically, the limit block 9 at the front end of the adjustment rod 8 is a cylindrical platform structure. The cylindrical platform structure can be disassembled and connected by threads for convenient manual control, and the other end is a limit structure that is conveniently embedded in the second airflow adjustment plate 6 to form a connection and matching relationship;

[0033] When the staff needs to adjust the resistance during the patient's breathing, the adjusting rod 8 is toggled downward to synchronously rotate the second air flow regulating plate 6 inside the connecting pipe 3. When it rotates to the position of the limiting groove 10, the limiting block 9 is simultaneously snapped into it to fix the second air flow regulating plate 6, causing the holes on the first air flow regulating plate 5 and the second air flow regulating plate 6 to bifurcate. When the gap between the holes changes, the resistance during the patient's breathing can be adjusted to make it suitable for patients with different rehabilitation degrees.

[0034] As Figure 2 and Figure 6 shown, in this implementation scheme: an annular side seal 12 is installed inside the above-mentioned connecting pipe 3;

[0035] Since the inner wall of the connecting pipe 3 and the outer edge of the second air flow regulating plate 6 are both made of rigid material structures, rotation between the two cannot achieve sealing. Therefore, the annular side seal 12 is designed; the outer convex portion 121 can be embedded into the main installation groove 123 at the inner wall of the connecting pipe 3, and then the C-shaped groove portion 122 contacts the outer edge of the rotatable second air flow regulating plate 6 and achieves sealing; for this, in order to ensure the realization of the dynamic sealing structure, the edge surface of the second air flow regulating plate 6 is designed as a smooth curved surface that converges towards both sides, so that the second air flow regulating plate 6 can rotate a certain angle along the C-shaped groove portion 122 of the annular side seal 12 under the condition of ensuring a certain sealing performance.

[0036] Analyzing the above scheme, it can be seen that: through the setting of the annular side seal 12, when the patient blows air into the contact nozzle 4, good airtightness can be maintained inside it, thereby increasing the accuracy during the adjustment of the breathing resistance.

[0037] As Figure 3 shown, the ventilation holes 18 on the first air flow regulating plate 5 can be in a fan shape, while the ventilation holes 18 provided on the second air flow regulating plate 6 can be fan-shaped through holes opened on the entire plane or composed of multiple circular holes;

[0038] As Figure 1 shown, in this implementation scheme: a breathing timer 13 is installed on one side of the gripping seat 1. Through the setting of the breathing timer 13, when the patient is performing breathing exercises, the number of breaths at one time can be accurately recorded, thereby improving the patient's usage experience.

[0039] As Figure 1 shown, in this implementation scheme: arc-shaped grooves 14 are opened on both the front side and the rear side of the rod wall of the gripping seat 1. Through the setting of the arc-shaped grooves 14, when the patient grips the gripping seat 1, it can fit more closely to the hand curve, thereby improving the stability of the grip.

[0040] As Figure 2 And Figure 4As shown, in this embodiment: the number of the limiting grooves 10 is four and they are evenly distributed inside the adjusting groove 7. Through the arrangement of the four adjusting grooves 7, the second air flow adjusting plate 6 can be adjusted in four gears during rotation, making it more convenient to use.

[0041] As Figure 5 shown, in this embodiment: an installation plate 15 is installed inside the connecting pipe 3. Clamping grooves 16 are formed on both sides of the installation plate 15. Clamping columns 17 are installed on both sides inside the contact nozzle 4. Inside the connecting pipe 3, an installation plate 15 is ingeniously arranged. Clamping grooves 16 are carefully designed on both sides of this installation plate 15 to ensure stability and reliability.

[0042] Meanwhile, in this embodiment: clamping columns 17 are installed on both sides inside the contact nozzle 4. These clamping columns 17 are perfectly matched with the clamping grooves 16 on the installation plate 15, forming a stable connection structure.

[0043] In summary, the adjustable breathing resistance handheld breathing trainer provided by the embodiment of the present invention has the technical advantages of being convenient to adjust, highly practical and having good sealing. The specific use process is described in detail as follows: when the staff needs to adjust the resistance during the patient's breathing, the adjusting rod 8 is toggled downward to make the second air flow adjusting plate 6 rotate synchronously inside the connecting pipe 3. When it rotates to the position of the limiting groove 10, the limiting block 9 is simultaneously clamped into it to fix the second air flow adjusting plate 6, and the holes on the first air flow adjusting plate 5 and the second air flow adjusting plate 6 are bifurcated;

[0044] When the gap between the holes changes, the adjustment of the resistance during the patient's breathing can be achieved, making it applicable to patients with different rehabilitation degrees. Through the arrangement of the annular side seal 12, when the patient blows air into the contact nozzle 4, good airtightness can be maintained inside it, thereby increasing the accuracy during the adjustment of the breathing resistance. Through the arrangement of the breathing timer 13, when the patient is performing breathing exercises, the number of breaths at one time can be accurately recorded, thereby improving the patient's use experience.

[0045] Finally, it should be noted that: the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail in the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
