Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a turbine water inlet detection device for a ventilator. Background Art
[0002] A ventilator is an important medical device used to assist patients in breathing.
[0003] In a ventilator, the turbine is a key component responsible for inhaling and exhausting gases. However, since most users lack operational training, the turbine of the ventilator often gets water ingress due to improper operation by the user, and continues to be used after getting water ingress, which will cause the ventilator to malfunction and even pose a serious health threat to the patient. Currently, almost all home ventilators use the current and temperature inside the turbine to determine whether there is an abnormality in the working state of the turbine. For example, if the turbine continues to run without control after getting water in, it may cause a short circuit due to water ingress in the coil, resulting in increased current and higher temperature. Monitoring the dry and wet state of the turbine in this way has great hysteresis and inaccuracy. If the turbine is not identified in time and continues to operate when it is flooded, it may cause an adverse effect on the user's respiratory system due to a short circuit.
[0004] Therefore, finding an appropriate method for detecting water ingress into a turbine is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0005] In view of the problem that the prior art is not accurate enough in detecting water ingress into the turbine, the purpose of the utility model is to provide a turbine water ingress detection device for a ventilator, which can improve the accuracy of detecting water ingress into the turbine.
[0006] The present application provides a turbine water ingress detection device for a ventilator, comprising: a detection test strip, an LED detection light, a color sensor, and a main control module;
[0007] A test paper, facing the internal air outlet of the turbine, for detecting the humidity of the internal air outlet of the turbine;
[0008] An LED detection light, wherein the irradiation working surface of the LED detection light faces the detection test paper, and the LED detection light is used to illuminate the detection test paper to observe the characteristic color of the detection test paper;
[0009] A color sensor, used to obtain the characteristic color of the test paper;
[0010] A main control module, used to control the operating state of the ventilator according to the characterization color;
[0011] The LED detection light and the color sensor are both electrically connected to the main control module.
[0012] Furthermore, the test paper is arranged on the turbo sponge, and the test paper is attached to the turbo sponge.
[0013] Furthermore, the main control module controls the turning on or off of the LED detection light.
[0014] Further, when the main control module controls the LED detection light to turn on;
[0015] The color sensor transmits the acquired characteristic color of the test paper to the main control module; the main control module analyzes the acquired characteristic color to send a control signal to control the operating state of the ventilator.
[0016] Furthermore, the test paper has two representative colors. When the LED test light shines on the test paper with a first representative color, the humidity at the internal air outlet of the turbine is normal; when the LED test light shines on the test paper with a second representative color, the humidity at the internal air outlet of the turbine is abnormal.
[0017] Furthermore, it also includes an alarm component, which is electrically connected to the main control module and is used to issue a prompt according to the representative color.
[0018] Furthermore, the alarm component is a buzzer.
[0019] Furthermore, the model of the color sensor is ADPD2211.
[0020] Compared with the prior art, the beneficial effect lies in that, by setting up a test paper, an LED test light, a color sensor, and a main control module, when the test paper set at the internal air outlet of the turbine is characterized by an abnormal humidity color under the illumination of the LED test light due to excessive humidity, the color sensor is used to identify the characteristic color and send a stop signal to the ventilator, thereby stopping the ventilator in time to prevent greater hidden dangers. The method provided by the present application can timely and accurately identify whether the turbine of the ventilator has entered water, greatly improving the safety and stability of the ventilator and improving the user experience.

[0030] In a ventilator, the turbine is a key component responsible for inhaling and exhausting gases. However, since most users lack operational training, the turbine of the ventilator often gets water ingress due to improper operation by the user, and continues to be used after getting water ingress, which will cause the ventilator to malfunction and even pose a serious health threat to the patient. Currently, almost all home ventilators use the current and temperature inside the turbine to determine whether there is an abnormality in the working state of the turbine. For example, if the turbine continues to run without control after getting water in, it may cause a short circuit due to water ingress in the coil, resulting in increased current and higher temperature. Monitoring the dry and wet state of the turbine in this way has great hysteresis and inaccuracy. If the turbine is not identified in time and continues to operate when it is flooded, it may cause an adverse effect on the user's respiratory system due to a short circuit.
[0031] See also Figure 1 and Figure 2 As shown, in one of the embodiments, the present application provides a turbine water ingress detection device for a ventilator, comprising: a detection test paper 11, an LED detection light 12, a color sensor 13, and a main control module 20;
[0032] A test paper 11, facing the internal air outlet 30 of the turbine, is used to detect the humidity of the internal air outlet 30 of the turbine;
[0033] An LED detection light 12, wherein the irradiation working surface of the LED detection light 12 faces the detection test paper 11, and the LED detection light 12 is used to illuminate the detection test paper 11 to observe the characteristic color of the detection test paper 11;
[0034] A color sensor 13, used to obtain the characteristic color of the test paper 11;
[0035] A main control module 20, used to control the operating state of the ventilator according to the characterizing color;
[0036] The LED detection light 12 and the color sensor 13 are both electrically connected to the main control module 20 .
[0037] It should be noted that the test paper 11 is a liquid test paper 11, that is, it can detect the water vapor content of the internal air outlet 30 of the turbine to reflect the humidity; when the LED detection light 12 is shone on the test paper 11, the test paper will have a representative color, if the humidity is normal, it will be represented by the first color, if the humidity is abnormal, it will be represented by the second color; the color sensor 13 can identify the representative color of the test paper 11 and send it to the main control module 20. After receiving the representative color signal, the active module will determine that if the representative color corresponds to normal humidity, the ventilator is operating normally, and if the representative color corresponds to abnormal humidity, the ventilator will stop working.
[0038] Compared with the prior art, the beneficial effect lies in that, by setting a test paper 11, an LED test light 12, a color sensor 13, and a main control module 20, when the test paper 11 set at the internal air outlet 30 of the turbine is characterized by a color representing abnormal humidity under the illumination of the LED test light 12 due to excessive humidity, the color sensor 13 identifies the characteristic color and sends a stop signal to the ventilator, thereby stopping the ventilator in time to prevent greater hidden dangers. The method provided by the present application can timely and accurately identify whether the turbine of the ventilator has entered water, greatly improving the safety and stability of the ventilator and improving the user experience.
[0039] In one embodiment, the test paper 11 is disposed on the turbo sponge 31 , and the test paper 11 is attached to the turbo sponge 31 .
[0040] It should be noted that setting the test paper 11 on the turbo sponge 31 is convenient for fixing the test paper 11, which is simple and convenient.
[0041] In one embodiment, the main control module 20 controls the LED detection light 12 to be turned on or off.
[0042] It should be noted that the detection test paper 11 can be made to represent the color by controlling the opening of the LED detection light 12. The detection cycle can be set according to the actual situation. In the current cycle, the LED detection light 12 is turned on to illuminate the detection test paper 11 to detect whether the turbine is flooded in the current cycle. If water is in, the main control module 20 turns on the prompt sound and stops the ventilator from working. If water is not detected in the turbine, the LED detection light 12 is turned off to save energy. Of course, it can also be turned on all the time for real-time monitoring. Of course, it can also be turned on periodically for regular testing. Those skilled in the art can set it according to the actual situation.
[0043] In one of the embodiments, when the main control module 20 controls the LED detection light 12 to turn on;
[0044] The color sensor 13 transmits the acquired characteristic color of the test paper 11 to the main control module 20; the main control module 20 analyzes the acquired characteristic color to send a control signal to control the operating state of the ventilator.
[0045] It should be noted that when the characteristic color corresponds to normal humidity, the ventilator operates normally; when the characteristic color corresponds to abnormal humidity, the ventilator stops working.
[0046] In one embodiment, the test paper 11 has two representative colors. When the LED test light 12 shines on the test paper 11 and the representative color is the first color, the humidity of the internal air outlet 30 of the turbine is normal; when the LED test light 12 shines on the test paper 11 and the representative color is the second color, the humidity of the internal air outlet 30 of the turbine is abnormal.
[0047] It should be noted that the humidity at the turbine outlet is reflected by detecting the change in the color of the test paper 11, so as to quickly, timely and accurately determine whether water has entered the turbine.
[0048] In one embodiment, an alarm component is further included. The alarm component is electrically connected to the main control module 20 and is used to issue a prompt according to the representative color.
[0049] It should be noted that when the color represents the normal humidity, the alarm component does not work, and when the color represents the abnormal humidity, the alarm component responds. The alarm component can be a warning light or a warning sound.
[0050] In one embodiment, the alarm component is a buzzer.
[0051] It should be noted that when the color representing the humidity is abnormal, the buzzer sounds.
[0052] In one embodiment, the model of the color sensor 13 is ADPD2211.
[0053] It should be noted that the color of the test paper 11 is identified by the color sensor 13 .
[0054] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
