[0011] In a second aspect, embodiments of the present application further provide a method for controlling an air disinfection and purification device, comprising the following steps: providing the air disinfection and purification device of any of the above embodiments; activating the air disinfection and purification device so that a user inhales disinfected and purified air, and the user exhales air that has been disinfected and purified and then discharged.

[0012] In some embodiments, after sensing that the user is wearing the respiratory device and inhaling, the respiratory device controls the air intake; after sensing that the user is wearing the respiratory device and exhaling, the respiratory device controls the air exhalation.

[0013] In some embodiments, the air intake of the respiratory unit is controlled to meet the user's breathing needs, and the air output of the respiratory unit is controlled to meet the user's breathing needs. Alternatively, the air intake of the respiratory unit is controlled to meet a set air intake volume, and the air output of the respiratory unit is controlled to meet a set air output volume.

[0014] In some embodiments, the air intake volume of the respiratory control unit increases as the user's breathing needs increase, and decreases as the user's breathing needs decrease, and the air output volume of the respiratory control unit increases as the user's breathing needs increase, and decreases as the user's breathing needs decrease.

The breathing unit has a breathing cavity. The plasma shock generator has a shock flow channel connecting the breathing cavity with the external environment. The plasma shock generator is configured to sterilize and purify gas flowing through the shock flow channel through electric shock.

[0019] The device of the present application has the following beneficial effects:

[0020] 1. The first plasma shock generator and the second plasma shock generator in the device of the present application can destroy the genes of microorganisms and viruses in the air, and can also decompose organic compounds in the air to achieve the effect of purifying the air. The above process uses physical effects entirely without the use of any chemical substances, and there will be no secondary pollution or virus amplification. Moreover, the above process only requires electrical energy and does not require the assistance of other special environments to produce an effective reaction to substances in the air. In addition, the purified air can be directly inhaled by the human body without any side effects. The first plasma shock generator and the second plasma shock generator in the device of the present application have high air disinfection and purification efficiency and low energy consumption.

[0021] 2. The device of the present application allows ambient air to flow into the plasma shock generator to be disinfected and purified, and then be delivered to the respiratory part for the user to inhale. The gas exhaled by the user flows into the plasma shock generator to be disinfected and purified, and then be delivered to the environment, thereby breaking the transmission chain as quickly as possible. The user and the people around the user will not be infected by viruses and bacteria, thereby reducing the chances of cross infection and virus mutation.

[0022] 3. The device of the present application is self-cleaning and can be used for a long time and reused multiple times.

[0023] 4. The device of the present application can disinfect and purify the gas according to the user's breathing needs, and has the function of automatically adjusting the gas volume, so that the user can move and work comfortably in crowded environments (such as hospitals and subways). For example, when the user's activity intensity increases, the inhalation and exhalation volumes increase. At this time, the gas disinfection and purification volume of the device is increased to ensure that the user will not be infected or infect the surrounding people.

[0024] 5. The device of the present application reduces battery consumption and extends battery life by automatically adjusting the gas volume and appropriate efficacy to avoid being in a high energy consumption and wasteful state for a long time. For example, when the user's activity intensity decreases, the inhalation and exhalation volumes decrease. At this time, the gas disinfection and purification volume of the device is reduced, which saves battery power while ensuring that the user and the surrounding people will not be cross-infected, making the device of the present application easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without paying any creative work.

[0026] Figure 1 Schematic diagram of the structure of the device in the embodiment of the present application. DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] Currently, drug-resistant bacteria, mutant viruses, and harmful organic compounds are increasing in the air, especially those that mutate at an accelerated rate. Neither medication nor vaccines can provide timely protection. While virus-infected individuals generally don't show obvious symptoms during the incubation period, the air they exhale may already carry the virus. To quickly break the chain of transmission, both inhaled and exhaled viruses must be eliminated. As long as humans remain uninfected, the chances of the virus mutating are reduced, allowing vaccines to be effective. To protect both the user and those around them, users inhale disinfected and purified air, and exhale disinfected and purified air before exhalation, ensuring that those around them are protected from infection and reducing cross-infection.
