DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific figures.

[0018] The prior art of the present application is a common three-ball breathing training device on the market. Since it is relatively common, those skilled in the art can easily query the specific structure of the three-ball breathing training device, so the specific structure of the three-ball breathing training device is not described in detail in this application. The present application provides a breathing training device, which is mainly different from the three-ball breathing training device on the market in that: first, the breathing training device of the present application is composed of only one balloon, one cylinder and one base; second, the resistance adjustment mode of the breathing training device of the present application is different from that of the three-ball breathing training device. The resistance adjustment of the breathing training device of the present application is achieved by adjusting the inclination angle of the cylinder.

[0019] Specifically, referring to Figures 1 to 4The utility model provides a kind of respiratory training device, it includes cylinder, support seat, balloon and air inlet pipe, wherein cylinder is long strip hollow structure, as similar to hollow structure of cylinder in drawing, cylinder has air inlet at bottom, and air outlet at top, one end of air inlet pipe is communicated with air inlet, and the other end is used for the mouth of human blowing, support seat and the middle part of cylinder are rotatably connected, by adjusting and maintaining the specific inclination angle of cylinder, the rising path angle of balloon is stable, cylinder preferably adopts transparent material to facilitate personnel to observe directly (if cooperate with angle sensor, distance sensor and master control device in the following, also can adopt opaque material), balloon is placed in the inside of cylinder, compared with the ball of traditional three-ball respiratory training device, balloon should have more weight, and in order to reduce the height of balloon rising after long time use, friction will affect, clearance fit between balloon and the inner wall of cylinder should be used, for example, the weight of balloon is designed at about 20g, the clearance between balloon and the inner wall of cylinder is designed as 0.2mm spacing, the diameter of balloon is 4cm, when cylinder is in the state of inclination, balloon is kept in stable state by the lateral support force and gravity of cylinder, when human blows into the inside of cylinder through air inlet pipe, the power generated by blowing overcomes the gravity component of balloon along the axis direction of cylinder downwards, so that ball can move upwards along the axis path of cylinder, thus, the closer cylinder is to vertical state, the more difficult balloon is blown to the position of the top of cylinder, and similarly, when cylinder is closer to vertical state, and is blown higher, it indicates that the respiratory state of human is better.

[0020] Specifically, as shown in Figure 4 And Figure 5 Two symmetrical support rods are fixedly connected to the middle part of the outer wall of the cylinder, the support seat includes a base and a stand plate arranged on the base and corresponding to the two support rods, the support rod and the stand plate are rotatably connected, that is, when the angle between the cylinder and the support seat is adjusted, the stand plate and the support rod rotate relative to each other, the support rod includes two parts, a first part fixedly connected to the outer wall of the cylinder and relatively thick, which is named as the first section, and a second part integrally formed with the first section and relatively thin, which is named as the second section, the specific shape of the support rod is a stepped rod, as shown in Figure 6 And Figure 7As shown, the vertical plate has a through-hole only for the second section to pass through (in order to achieve smooth rotation, the outer diameter of the second section is smaller than the inner diameter of the through-hole), and a threaded hole is also provided on the support rod. The threaded hole cooperates with a threaded locking piece to lock the cylinder at a specific angle. The threaded locking piece includes a threaded rod and an extrusion cap integrally formed at one end of the threaded rod. It can be clearly seen from the accompanying drawings that the length of the threaded rod is greater than the length of the extrusion cap, so when the threaded rod is screwed into the threaded hole a certain distance, the extrusion cap will squeeze the vertical plate to generate sufficient friction to achieve the angular positioning of the cylinder on the support seat. When the angle of the cylinder needs to be adjusted, the threaded rod is rotated in the opposite direction to disengage the extrusion cap from the vertical plate, and it can be adjusted. After adjustment, it can be tightened again.

[0021] like Figure 8 As shown, in order to automatically judge whether the current breathing state of a person is good, the breathing training device also includes a main control device, a distance sensor and an angle sensor, wherein the angle sensor is arranged at the connection between the support base and the cylinder, and the distance sensor is arranged on the top of the cylinder. The output ends of the distance sensor and the angle sensor are both connected to the input end of the main control device. The main control device judges the breathing state of the human body based on the signals of the angle sensor and the distance sensor. During the judgment process, the main control device judges based on the angle signal of the angle sensor and the distance signal of the distance sensor. The judgment result is shown as follows: Figure 11 As shown, the judging conditions are every thirty angles and every five centimeters as conditions for judging. The five judging standard results can be represented by Chinese characters. The judging standard results include poor, poor, normal, better and excellent. Of course, the judging conditions and judging standards are not limited to the above-mentioned one way of expression. For example, the level of the judging conditions can be divided more finely, such as every five degrees and every 2 centimeters as a level standard. The judging results can also be more diversified, such as directly using numbers for judging, with zero to twenty numbers as the judging standard. The larger the number, the better the breathing state. The specific main control device has a display screen for displaying the corresponding judging results.

[0022] The above-mentioned distance sensor can be a laser distance sensor, an infrared distance sensor or an ultrasonic distance sensor. The detection principle is based on emitting a light beam or sound wave from the top of the cylinder to the bottom of the cylinder along the axis of the cylinder. After the light beam or sound wave contacts the balloon, it bounces back to the distance sensor on the top. The distance of the balloon is judged according to the time it takes for the light beam or sound wave to reflect back. The specific main control device can judge the distance between the distance sensor and the balloon by receiving the signal from the distance sensor. The rising height of the balloon can be obtained by subtracting the distance between the distance sensor and the balloon from the total length of the cylinder.

[0023] like Figure 9 Shown and Figure 10As shown, the above-mentioned angle sensor includes a fan-shaped plate and a conductive rod electrically contacting the fan-shaped plate, and a main control device with a power supply module and a current monitoring module inside. The main control device has a circuit board inside, and a processing module for processing signals, a current monitoring module for monitoring current, and a power supply module for providing voltage are all integrated on the circuit board. The power supply module is used to provide a stable voltage, and the current monitoring module is used to monitor the current passing through the conductive rod and the fan-shaped plate. The voltage provided by the power supply module of the main control device is constant. When the conductive rod contacts different positions of the fan-shaped plate, the current monitored by the current monitoring module is different. The resistance of the access circuit can be calculated by the ratio of voltage to current. The length of the current fan-shaped plate access circuit can be obtained based on the size of the resistance value. The deflection angle of the cylinder can be calculated based on the length of the fan-shaped plate access circuit. The above-mentioned fan-shaped plate is made of a material with balanced resistivity to ensure that when the conductive rod is in linear contact with the fan-shaped plate, the resistance can change linearly in a stable manner.
