Description

Technical Field

[0001] The present application relates to the technical field of respiratory equipment, and in particular to a cleaning device for respiratory equipment. Background Art

[0002] Sleep apnea (OSA) is a common sleep disorder that can easily lead to complications such as diabetes and cerebrovascular disease, and even sudden death at night. Sleep apnea machines are the main treatment for obstructive sleep apnea (OSA). When using a ventilator for a long time in a home environment, regular cleaning and maintenance are very important. If it is not cleaned in time, it will directly affect the cleanliness of the air. Continuous use of contaminated ventilators for treatment may cause a person's lungs to become infected.

[0003] In the prior art, the cleaning methods of the ventilator water tank are mainly manual cleaning and dishwasher cleaning. Manual cleaning generally requires repeated cleaning with warm water according to the instructions after the heating plate has cooled down, and then wiping the outer surface with a towel or the like and drying it in the sun. However, since the user has to wait for the heating plate to cool down before cleaning, it wastes the user's time, and the water tank has a complex structure and is not easy to clean in hidden places. Dishwasher cleaning requires the water tank to be disassembled, and then the disassembled water tank and each water tank component are cleaned in a dishwasher. This method requires disassembly and assembly and requires the purchase of an additional dishwasher, which is cumbersome to operate and increases costs. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature.

[0030] In order to make the content of this application more clearly and accurately understood, it will now be described in detail with reference to the accompanying drawings. The accompanying drawings in the specification illustrate examples of embodiments of the present application, wherein the same reference numerals represent the same elements. It is understood that the scales shown in the accompanying drawings in the specification are not the scales actually implemented in this application, and are only for the purpose of illustrative description, and are not drawn according to the original size.

[0031] Please see Figure 1 , Figure 1The structure diagram of the respiratory device provided in the embodiment of the present application. The respiratory device 1 comprises: a host 10, and an ultrasonic cleaning device 101 disposed on the host 10 and used to clean the water tank 100. The ultrasonic cleaning device 101 comprises: an ultrasonic signal generator 1010, a main control board 1011, an ultrasonic transducer 1012, and a vibration plate 1013.

[0032] The main control board 1011 is connected to the ultrasonic signal generator 1010 for controlling the ultrasonic signal generator 1010 to transmit an electrical signal of a preset frequency. Specifically, the main control board 1011 controls the ultrasonic signal generator 1010 to transmit an electrical signal of a preset frequency through an electrical signal. The ultrasonic signal generator 1010 is integrated in the main control board 1011. The frequency band of the electrical signal of the preset frequency is below 40KHZ or above 1000KHZ. In this embodiment, the main control board 1011 controls the ultrasonic signal generator 1010 to transmit an electrical signal with a frequency of 35KHZ.

[0033] Please see Figure 2 , Figure 2 A scenario application diagram of the respiratory device provided in the embodiment of the present application. When the ultrasonic wave emitted by the ultrasonic transducer 1012 propagates in the liquid, it causes the bubbles in the liquid to vibrate, generating a cavitation effect, and some cavitation bubbles rupture to generate shock waves. The shock wave can generate thousands of atmospheric pressures around it, directly and repeatedly impacting the dirt layer at the water tank 100, causing the dirt to detach from the surface of the water tank 100 and disperse into the cleaning liquid. The cavitation effect generates high-speed microjets on the surface of the water tank 100 and the surface of the liquid to weaken the dirt layer at the boundary of the water tank 100, accelerate stirring, and enhance the cleaning effect.

[0034] Specifically, the ultrasonic transducer 1012 includes a plurality of ultrasonic transducer units 10120 arranged side by side at the bottom of the vibration plate 1013, and each ultrasonic transducer unit 10120 is identical.

[0035] The ultrasonic transducer 1012 is connected to the ultrasonic signal generator 1010 for communication, and is used to convert the electrical signal emitted by the ultrasonic signal generator 1010 into an ultrasonic wave of a corresponding frequency. Specifically, the ultrasonic transducer 1012 is connected to the ultrasonic signal generator 1010 for communication via a lead wire. The ultrasonic transducer 1012 receives the electrical signal emitted by the ultrasonic signal generator 1010, and converts the received electrical signal into an ultrasonic wave of a corresponding frequency.

[0036] In this embodiment, the ultrasonic transducer 1012 receives the 35 kHz electrical signal emitted by the ultrasonic signal generator 1010 , and the ultrasonic transducer 1012 converts the 35 kHz electrical signal into a 35 kHz ultrasonic wave.

[0037] Please see again Figure 1The vibration plate 1013 is disposed between the water tank 100 and the ultrasonic transducer 1012, and is against the water tank 100 and the ultrasonic transducer 1012. The vibration plate 1013 transfers the ultrasonic radiation energy generated by the ultrasonic transducer 1012 to the liquid in the water tank, thereby causing the liquid in the water tank to generate bubble vibration.

[0038] The vibration plate 1013 is a plate-shaped object, which can be a heating plate of the water tank 100 or a side wall of the water tank 100. The shape and position of the vibration plate 1013 are set according to actual conditions. If it is a heating plate, it can be set at the bottom of the heating plate. If it is a side wall, it can be set adjacent to the side wall. It is not limited here.

[0039] In one embodiment, the ultrasonic wave generated by the ultrasonic transducer 1012 will cause the vibration plate 1013 to vibrate, and the vibration of the vibration plate 1013 will cause the water tank 100 to vibrate. However, the vibration of the water tank is not the principle of cleaning, but is only a side effect that may be caused during the ultrasonic transmission process. Some transducers will not cause vibration of the conductive object when emitting ultrasonic waves.

[0040] The ultrasonic radiation energy generated by the ultrasonic transducer 1012 will cause the vibration of the cavitation bubbles inside the water tank 100. The vibration of the cavitation bubbles will cause a high velocity gradient and viscous stress on the surface of the cavitation bubbles to promote the shedding of dirt on the surface of the water tank 100. Some cavitation bubbles enter the cracks of the water tank 100, and the dirt on the surface of the cracks will fall off through the continuous vibration of the bubbles themselves. The cavitation bubbles clean the cracks in the water tank 100 through vibration, making the water tank 100 clean more thoroughly.

[0041] The ultrasonic cleaning device 101 can be started after the respiratory device 1 is heated. Specifically, after the user uses the respiratory device 1, the ultrasonic cleaning device 101 can be directly started to clean the water tank 100. The user does not need to wait for the heating plate to cool down before cleaning, which saves the user's waiting time. Functionally, the ultrasonic cleaning and heating of the water tank can be used independently, without the need for a sequence. However, from the user's usage behavior, after the ventilator is heated for use, daily water tank cleaning can be performed directly, which is a more convenient method. After the ventilator is heated for use, the temperature of the water rises, and the cleaning effect is better.

[0042] In this embodiment, the user turns on the respiratory device 1, and the heating plate of the respiratory device 1 is heated. After the user finishes using the device, the user directly turns on the ultrasonic cleaning device 101 to clean the water tank 100.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.

[0044] The above examples are only preferred embodiments of the present application, and certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
