Description

Technical Field

[0001] The present invention relates to the technical field of respiratory function training, in particular to an electronic candle device for respiratory function training and a training method. Background Art

[0002] Respiratory function training is an important component of rehabilitation medicine, especially for patients with respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma, as well as those recovering from surgery. Traditional respiratory function training methods include blowing balloons and using breathing trainers, but these methods have certain limitations.

[0003] Existing respiratory function training devices often use a single trigger mechanism: a single pressure sensor or airflow sensor. This has low sensitivity and is susceptible to environmental interference, leading to false or missed triggers. Furthermore, the device lacks graded feedback, making it difficult to meet the training needs of different users (such as children, the elderly, or critically ill patients), resulting in a poor user experience. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide an electronic candle device and exercise method for respiratory function training, which has a mechanical-electronic hybrid trigger to improve sensitivity and reliability; a three-level adjustable pressure threshold to adapt to different user needs, simulate the effect of a real candle extinguishing, and enhance fun.

[0005] The present invention provides an electronic candle device for exercising respiratory function, comprising:

[0006] a housing including a transparent window;

[0007] A mechanical-electronic hybrid trigger module comprises: an airflow channel vertically penetrating the housing, a mechanical impeller in the middle of the airflow channel, and a membrane pressure switch mounted on the side wall; the pressure switch is triggered when the speed of the mechanical impeller reaches a set value (≥5 rpm);

[0008] Three-position physical dial switch for adjusting the pressure threshold;

[0009] The LED feedback candle assembly is located inside the housing and displays a gradual orange color change during blowing. When the target is met, the red color suddenly turns off and lights up after a set number of seconds.

[0010] The piezoelectric buzzer is located on the front of the housing and emits differentiated prompt sounds according to the blowing intensity;

[0011] The counting display screen is located on the front side of the shell to record the number of successful blow-outs per day;

[0012] A counterweight base (200g steel block) is located at the bottom of the shell.

[0013] Furthermore, the axial distance between the rotating axis of the mechanical wind wheel and the sensing surface of the membrane pressure switch is 3-5 cm, and the diameter of the air flow channel is 8 mm ± 0.5 mm.

[0014] Furthermore, the three-speed physical dip switch changes the pressure threshold by selecting resistors of different resistance values ​​(10kΩ / 22kΩ / 47kΩ) connected to the LM393 comparator.

[0015] Furthermore, the three thresholds of the three-level physical dip switch are: 0.2kPa, 0.5kPa, and 0.8kPa respectively.

[0016] Furthermore, the mechanical wind wheel is a polypropylene wind wheel with 6-8 blades and a blade inclination angle of 15°-20°. The user's blowing kinetic energy is converted into rotational mechanical energy, and the blowing effectiveness is verified by the rotation speed.

[0017] Furthermore, the LED feedback candle assembly includes a main control chip WS2812B chip for controlling the gradient light.

[0018] The present invention also provides a method for exercising the electronic candle device for exercising respiratory function, comprising the following steps:

[0019] S1: Initial state: LED feedback candle component is not lit;

[0020] S2: Air blowing trigger: The air blowing drives the mechanical wind wheel to rotate. When the speed of the mechanical wind wheel reaches the set value (≥5rpm), the membrane pressure switch signal triggers the LM393 comparator;

[0021] S3: Extinguishing feedback: When the target is met, the LED feedback candle assembly goes out suddenly, and the piezoelectric buzzer emits a beep; it lights up after the set number of seconds;

[0022] S4: Counting record: The counting display screen shows the cumulative number of successes.

[0023] Furthermore, in S2, the blade speed is monitored in real time through the wind wheel speed sensor. When the speed reaches the set value ≥5rpm, AD sampling is triggered to obtain the analog voltage signal of the membrane pressure switch; the pressure signal is input into the LM393 comparator and compared with the current gear threshold of the three-speed physical dial switch. After effective triggering, the LED feedback candle component's main control chip executes.

[0024] Furthermore, the sliding window algorithm is used to filter out instantaneous interference, and only when three consecutive sampling points exceed the threshold is it determined to be a valid trigger.

[0025] Further,

[0026] When the mechanical wind wheel speed does not reach the set value, the secondary calibration mode is started:

[0027] If the speed of the mechanical wind wheel reaches the set value but the pressure signal of the membrane pressure switch continues to be, it is determined that the air flow channel is blocked and the piezoelectric buzzer alarm is triggered.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] (1) Mechanical-electronic hybrid triggering improves sensitivity and reliability. A dual triggering mechanism using a mechanical wind wheel and a membrane pressure switch is used. Through dual verification of wind wheel speed and pressure signals, false triggering or missed triggering is effectively avoided, improving detection accuracy. Compared to a single electronic sensor, a mechanical wind wheel can more stably convert blowing kinetic energy into rotational mechanical energy, ensuring the accuracy of the trigger signal.

[0030] (2) Three adjustable pressure thresholds to meet different user needs. Dynamic visual and auditory feedback enhances the user experience. The LED feedback candle component displays a gradient orange when blowing, and then suddenly turns red and lights up after reaching the target, simulating the effect of a real candle being extinguished and enhancing the fun.
