When the breathing machine is started, the oxygen supply component starts to work, oxygen supply is responsible for generating or releasing oxygen, and the air inlet end of the first pipeline is communicated with the external environment and allows air to be inhaled from the external environment. The main function of the turbo fan is to generate air flow through rotation, the air flows through the formed negative pressure, a container is arranged in the atomization unit, when atomization treatment is needed, the unit can convert liquid medicine into tiny particles or mist, a first pipeline (mixed gas pipeline) and a second pipeline (atomization pipeline) are both connected to the air pipeline 4, and when a patient inhales, the mixed gas and the atomized medicine are inhaled simultaneously.

Referring to fig. 11, further, the air supply unit 1 further includes an air filtering member 12 located at the air inlet end of the first pipeline.

Referring to fig. 12, fig. 12 is a top view of a cover member according to an embodiment, wherein the display area includes a first display area disposed at a periphery of the gas transmission area, a second display area disposed at a periphery of the first display area, and a third display area disposed at a periphery of the second display area; when the container is in a state to be cleaned, the different display areas display different step information related to cleaning the container, and continuing to refer to fig. 12, wherein the part a filling area is a first display area, the part B filling area is a second display area, and the part C filling area is a third display area.

Specifically, in the present invention, the cover member 3 is specifically designed with three display areas: the display device comprises a first display area, a second display area and a third display area. The three areas are arranged on the periphery of the opening in a layer-by-layer and clear manner to form a surrounding display structure, the shape of the display area can be a ring shape or a square frame shape, and the size of each display area is not particularly limited.

For example, the first display area is located at the innermost periphery of the opening, and is the area that is focused first by the user when performing the cleaning operation. The method is mainly used for displaying the most direct and most critical information of container cleaning, such as the real-time state of the current cleaning step, whether cleaning agent needs to be added, the cleaning progress and the like, and the information of the first area is most important for users, and large fonts, striking colors or dynamic effects are used during design so as to ensure that the users can quickly capture the critical information.

The second display area is arranged at the periphery of the first display area, providing more detailed operation guidance. The second display area will show how the cleaning unit 22b is used properly for cleaning, including the parameters set for the amount of detergent used, the cleaning time, the cleaning speed, etc.

The third display area is used as the outermost display area and mainly bears the task of auxiliary information display. The third display area is located on the outermost layer, which provides more comprehensive and thorough cleaning-related information, and may include history of cleaning containers, comparisons of different cleaning methods, maintenance advice for the containers after cleaning, and the like. Through the third display area, the user can acquire more comprehensive cleaning knowledge, thereby improving cleaning efficiency and the service life of the container.

For example, when it is detected that the container needs to be cleaned, the first display area may first send a prompt, such as displaying words of "please prepare to clean the container", while the second display area may provide a preparation instruction before cleaning, such as "please ensure no residue in the container", "prepare to clean the tool and cleaning agent", etc., and during the cleaning process, the first display area may update the information of the cleaning step, such as "cleaning …", "cleaning completion 50%", etc. The second display area can provide specific operation guidelines for each step, such as "please add detergent", "place in container with clean water", etc., and the third display area can provide problems and solutions that may be encountered during the cleaning process, helping the user to cope with various emergencies. When the cleaning is completed, the first display area can display confirmation information such as 'cleaning completion', the second display area can provide maintenance advice after cleaning, such as 'please store the container after airing', 'periodically check the state of the container', and the third display area can provide a use record and maintenance log of the container, so that a user can better manage and maintain the container.

In summary, in the present disclosure, the cleaning state of the container used by the ventilator is determined by using the light emitting surface at the bottom of the container and the light emitting intensity thereof, and specifically, when the container is in the preset first state, for example, after regular or every use, the system starts the photosensitive member to detect the light emitting intensity of the light emitting surface. The photosensitive member converts the intensity of light into an electrical signal and compares it with a preset first threshold. If the light output intensity is higher than the first threshold value, the container is in a normal state and no cleaning is needed. If the intensity is lower than the first threshold value but higher than the second threshold value, the container is in a state to be cleaned, and the cleaning unit automatically starts to clean the bottom of the container, particularly the light-emitting surface.

The present invention is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed within the scope of the present invention.
