[0027] Embodiment one

[0028] Please refer to Figures 1-7 , the present application provides a kind of equipment for pediatric cardiovascular rehabilitation training activity, including blowing pipe 1 and rubber push rod 3, the right end of blowing pipe 1 is fixedly installed with elbow pipe 11, the top of elbow pipe 11 is fixedly installed with horn pipe 12, rubber push rod 3 is slidably arranged in blowing pipe 1, and the right end of rubber push rod 3 extends into elbow pipe 11;

[0029] The inner wall of the blowing training end of blowing pipe 1 is provided with a blocking mechanism for blocking the backflow of blown gas into the oral cavity, and an air outlet hole 23 is formed on blowing pipe 1 near the blocking mechanism for discharging the blown gas. The blocking mechanism is rotatably arranged on the inner wall of blowing pipe 1 in a petal shape, and the blocking mechanism opens the sealed air outlet hole 23.

[0030] Please refer to Figure 2 and Figure 5 , the backflow of gas is blocked and released by the blocking mechanism, thereby preventing backflow into the child's body and causing certain impact on the child.

[0031] The inner wall of blowing pipe 1 and located at the left end of rubber push rod 3 is swingably provided with an adjusting mechanism for adjusting the blowing size.

[0032] Please refer to Figure 2 , Figure 4 and Figure 7As shown, the training difficulty is adjusted according to the physical state of the child through the adjusting mechanism, so that the breathing training device can flexibly adjust the training intensity according to the training needs and progress of the child, thereby promoting the diversity and depth of the training effect, and further helping the comprehensive rehabilitation of the cardiopulmonary function of the child.

[0033] The inside of the horn pipe 12 reciprocally swings with a swing mechanism that increases the training fun, and the end of the rubber pushing rod 3 extending into the inside of the elbow pipe 11 is fixedly installed with the swing mechanism.

[0034] Please refer to Figure 2 、 Figure 3 and Figure 6 , the swing mechanism swings and emits sound, thereby increasing the fun and attracting the attention of the child, so that the child can maintain a happy mood while training.

[0035] In the above scheme, before use, the training difficulty is adjusted according to the physical state of the child by rotating the adjusting mechanism, and when the training difficulty is adjusted, the child blows air into the blowing pipe 1 through the left end of the blowing pipe 1, at this time, the left side of the blocking mechanism is forced to open to facilitate the flow of gas, so that the gas pushes the rubber pushing rod 3 to move to the right side through the adjusting mechanism, the rubber pushing rod 3 pushes the swing mechanism to move upward and swing, increasing the fun, when the child stops blowing, the swing mechanism moves downward due to its own gravity, at the same time, the swing mechanism pushes the adjusting mechanism to move to the left side through the rubber pushing rod 3, so that the adjusting mechanism pushes part of the gas to move to the left side, when part of the gas moves to the left side, the right side of the blocking mechanism is forced to close, and the gas is discharged, thereby preventing backflow into the child's body, so that the breathing training device can increase the fun of the child through the swing mechanism, and also adjust the blowing difficulty according to the physical state of the child through the adjusting mechanism, which means that the breathing training device can flexibly adjust the training intensity according to the training needs and progress of the child, thereby promoting the diversity and depth of the training effect, and further helping the comprehensive rehabilitation of the cardiopulmonary function of the child.

[0036] When the adjusting mechanism is in a sealed state, the child can more easily blow the swing mechanism, that is, adjust the blowing training difficulty, when the adjusting mechanism is in a leakage state, the difficulty of blowing the swing mechanism is increased, and the larger the leakage hole of the adjusting mechanism, the greater the difficulty of blowing the swing mechanism.

[0037] Specifically, the blocking mechanism includes a fixed ring 2 fixedly installed on the inner wall of the blowing pipe 1 close to the left end, the right side of the fixed ring 2 is provided with a plastic arc plate 21, the outer side of the plastic arc plate 21 is fixedly installed with a rubber baffle 22, and the inner wall of the blowing pipe 1 located to the right of the fixed ring 2 is provided with a gas outlet hole 23.

[0038] In the above scheme, when the child blows into the blow pipe 1 through the left end of the blow pipe 1, the left side of the plastic arc-shaped plate 21 is forced to open, facilitating the flow of air through the push adjustment mechanism. When the plastic arc-shaped plate 21 is opened, it deforms and opens away from the center of the circle. The plastic arc-shaped plate 21 drives the rubber baffle 22 to open and contact the inner wall of the blow pipe 1, thereby blocking the air outlet hole 23 to prevent air from flowing out through the air outlet hole 23. When the child stops blowing, the swing mechanism moves downward due to its own gravity, pushing the adjustment mechanism to move to the left through the rubber push rod 3. The adjustment mechanism pushes part of the gas to move to the left. When the part of the gas moves to the left and contacts the right side of the plastic arc-shaped plate 21, the right side of the plastic arc-shaped plate 21 is forced to close. The plastic arc-shaped plate 21 drives the rubber baffle 22 to move to a position close to the center of the circle. The rubber baffle 22 unblocks the air outlet hole 23, allowing the air to flow out through the air outlet hole 23. After the child blows, the backflow of gas is effectively discharged through the cooperation of the internal structure of the blocking mechanism, avoiding the backflow of gas into the child's body, causing irritation to the respiratory mucosa and discomfort such as respiratory distress, thereby positively promoting the overall recovery of the child's heart and lung function.

[0039] If this part directly uses a one-way valve, the child can perform normal training when blowing for the first time, but if the adjustment mechanism is in a sealed state, the one-way valve cannot discharge the gas in the blow pipe 1, and the gas will remain in the blow pipe 1. When the child blows for the second time, the one-way valve will produce a gas flow collision after opening, making it difficult for the child to perform normal training. If the first blowing amount is too large and the second blowing amount is too small, the backflow of gas after the collision will also cause irritation to the respiratory mucosa and discomfort such as respiratory distress.

[0040] Specifically, the blocking mechanism includes a moving disc 4 fixedly installed at the left end of the rubber push rod 3, the moving disc 4 is movably connected with the blow pipe 1, the left end of the moving disc 4 is rotatably connected with a rotating disc 41, an arc-shaped triangular air hole 42 is formed on the left side of the moving disc 4 away from the center of the circle, a square air hole 43 is formed on the left side of the rotating disc 41 corresponding to the arc-shaped triangular air hole 42, an adjusting ring 44 is rotatably connected with the inner wall of the blow pipe 1 at the left side of the rotating disc 41, a circular arc clamping groove 45 is formed on the right side of the adjusting ring 44, the right end of the circular arc clamping groove 45 is designed as a rounded corner, a circular arc clamping block 46 is fixedly installed on the left side of the rotating disc 41 away from the center of the circle, the left end of the circular arc clamping block 46 is clamped in the circular arc clamping groove 45, a circular arc communication hole 47 is formed on the same horizontal plane of the circular arc clamping groove 45 on the outer side of the blow pipe 1, an adjusting handle 48 is fixedly installed on the outer side of the adjusting ring 44, and the adjusting handle 48 is movably connected with the circular arc communication hole 47.

[0041] In the above scheme, the rotating adjusting handle 48 can adjust the difficulty of the breathing training. When the adjusting handle 48 is rotated to the front side by a certain angle, the adjusting handle 48 drives the adjusting ring 44 to rotate clockwise, the adjusting ring 44 drives the arc-shaped clamping block 46 to rotate through the arc-shaped clamping slot 45, the arc-shaped clamping block 46 drives the rotating disc 41 to rotate, the rotating disc 41 drives the square-shaped air hole 43 to rotate, and when the square-shaped air hole 43 rotates clockwise, the gap coinciding with the arc-shaped triangular air hole 42 becomes smaller, thereby increasing the air tightness between the rotating disc 41 and the oral cavity of the child, and reducing the difficulty of the breathing training. Similarly, when the adjusting handle 48 is rotated to the rear side by a certain angle, the working principle of increasing the training difficulty is the same as above. When the training difficulty is adjusted, in the process of the child blowing air, the airflow drives the rotating disc 41 to move to the right side, the rotating disc 41 drives the arc-shaped clamping block 46 to move to the right side to release the clamping with the arc-shaped clamping slot 45, the rotating disc 41 drives the moving disc 4 to move to the right side, the moving disc 4 drives the swing mechanism to swing through the rubber pushing rod 3, and when the child stops blowing air, the swing mechanism moves downward due to its own gravity to drive the rubber pushing rod 3 to drive the moving disc 4 to move to the left side. The moving disc 4 drives the rotating disc 41 to move to the left side, the rotating disc 41 drives the arc-shaped clamping block 46 to move to the left side to be clamped in the arc-shaped clamping slot 45. Since the arc-shaped clamping slot 45 is designed with a round corner, the arc-shaped clamping block 46 is clamped in the arc-shaped clamping slot 45. Through the cooperation of the adjusting ring 44 and the rotating disc 41 and other structures, the training difficulty is adjusted according to the physical condition of the child, so that the breathing training device can flexibly adjust the training intensity according to the training needs and progress of the child, thereby promoting the diversity and depth of the training effect, and further helping the comprehensive rehabilitation of the cardiopulmonary function of the child.

[0042] Specifically, the swing mechanism includes a transfer block 5, the transfer block 5 is fixedly installed at the right end of the rubber pushing rod 3, the top end of the transfer block 5 is rotationally connected with a swing spherical body 51, the swing spherical body 51 is clamped in the horn pipe 12, the outer side of the horn pipe 12 is provided with a swing clamping slot 52, the outer side of the swing spherical body 51 is fixedly installed with a swing clamping rod 53, the swing clamping rod 53 is movably clamped with the swing clamping slot 52, the swing clamping rod 53 extends out of the front end of the horn pipe 12 and is fixedly installed with a limiting circular block 54, the front end of the limiting circular block 54 is fixedly installed with a swing sound pipe 55, and the outer side bottom of the swing sound pipe 55 is provided with a cartoon flag 56.

[0043] In the above scheme, when the child exhales, the adjusting mechanism drives the transfer block 5 to move upwards through the rubber push rod 3, the transfer block 5 drives the swing ball 51 to move upwards, the swing ball 51 drives the swing clamping rod 53 to move upwards, the swing clamping rod 53 moves upwards along the swing clamping groove 52 to swing, the swing clamping rod 53 drives the swing ball 51 to rotate, the swing clamping rod 53 drives the limiting circular block 54 to move upwards while swinging, the limiting circular block 54 drives the swing sound pipe 55 to move upwards while swinging, the swing sound pipe 55 cooperates with the outside air to emit sound while moving upwards and swinging, the swing sound pipe 55 drives the cartoon flag 56 to move upwards while swinging, and the swing sound pipe 55 and the cartoon flag 56 are driven to move upwards while swinging and emitting sound through the cooperation of the swing clamping groove 52 and the swing clamping rod 53, thereby increasing the interest and attracting the attention of children, so that the children can train while maintaining a happy mood.

[0044] Specifically, the inner wall of the elbow pipe 11 is fixedly installed with a double-layer limiting plate, and the double-layer limiting plate is clamped on the upper and lower sides of the rubber push rod 3.

[0045] In the above scheme, the double-layer limiting plate limits the movement track of the rubber push rod 3, so that the rubber push rod 3 has a fixed movement track during left and right movement.

[0046] Specifically, a horizontal limiting groove is formed in the inner wall of the blowing pipe 1 near the right side, a horizontal limiting block is fixedly installed on the outer side of the moving disc 4, and the horizontal limiting groove and the horizontal limiting block are movably connected.

[0047] In the above scheme, the horizontal limiting groove and the horizontal limiting block movably connected increase the stability of the moving disc 4 during left and right movement, and also prevent the moving disc 4 from rotating during left and right movement.

[0048] Specifically, a circular ring friction strip is fixedly installed on the left side of the moving disc 4 away from the center, and the inner wall of the circular ring friction strip is in contact with the outer side of the rotating disc 41.

[0049] In the above scheme, the inner wall of the circular ring friction strip is in contact with the outer side of the rotating disc 41, which increases the stability of the rotating disc 41 during left and right movement and prevents the rotating disc 41 from rotating during movement.

[0050] Specifically, circular arc friction strips are fixedly installed on the left and right sides of the circular arc communication hole 47, and the two circular arc friction strips are in contact with the two sides of the adjusting handle 48.
