In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0031] In the daily life environment of human beings, various viruses and bacteria are widely present on the surface of objects and in the air. Human contact with viruses and bacteria may cause a variety of diseases. Effective disinfection is conducive to blocking the route of infection to ensure human health. In related technologies, the space can be sterilized and disinfected by ozone, ultraviolet rays, disinfectants or nano-water ions, but too high a concentration of ozone is harmful to the human body and has a peculiar smell; ultraviolet radiation is harmful to the human body and may cause accelerated aging of the parts of the ultraviolet lamp and the items in the space; the disinfectant is corrosive, and too high a concentration may cause corrosion of the items in the space, while insufficient concentration may result in poor disinfection effect; the generation of nano-water ions requires the use of moisture in the air, and the effect is poor in dry areas. Therefore, a sterilization device with a wider range of application scenarios and better sterilization effect is needed.

[0032] Based on this, refer to Figures 1 to 5 The sterilization device provided by the embodiment of the utility model includes a housing 100, an atomizing element 200, a nano water ion generator 300 and a fan 400. It should be noted that in order to better illustrate the structure of the sterilization device, Figure 1 The housing 100 is partially transparent. The housing 100 has a liquid storage chamber 110, a mounting chamber 120, an atomizing port 130, an air inlet 140 and an air outlet 150. The liquid storage chamber 110 is connected to the mounting chamber 120 through the atomizing port 130. The air inlet 140, the mounting chamber 120 and the air outlet 150 are connected in sequence. The liquid storage chamber 110 is used to contain disinfectant. The atomizing element 200 is connected to the housing 100, and the atomizing element 200 covers the atomizing port 130. The atomizing element 200 is used to atomize the liquid in the liquid storage chamber 110 into aerosol. And released into the installation cavity 120; the nano water ion generator 300 is located in the installation cavity 120, and the nano water ion generator 300 is used to ionize the moisture in the air in the installation cavity 120 into water ions; the fan 400 is located in the installation cavity 120, and the fan 400 is used to generate an airflow from the air inlet 140 to the air outlet 150, and the atomizer 200 and the nano water ion generator 300 are both located on the flow path of the airflow, and the airflow can drive the aerosol and water ions to be discharged from the air outlet 150.

[0033] The sterilization device provided by the embodiment of the utility model is provided with an atomizer 200 and a nano water ion generator 300. The atomizer 200 can atomize the disinfectant in the liquid storage chamber 110 into a disinfectant aerosol, and the disinfectant can kill pathogenic microorganisms; the nano water ion generator 300 can condense the moisture in the air on the surface of the needle electrode through the heat absorption cooler, and ionize the moisture condensed on the surface of the needle electrode into nano-scale water ions through high-voltage discharge. The OH free radicals exist in the water ions, which can decompose or inactivate the hydrogen (H) in organic matter such as odors, bacteria, allergens, etc., so as to kill pathogenic microorganisms. The airflow generated by the fan 400 can drive the water ions and the disinfectant aerosol to be discharged from the air outlet 150 to the space where the sterilization device is located. The water ions and the disinfectant aerosol work together to achieve sterilization and disinfection of the space.

[0034] On the one hand, the sterilization device can generate both disinfectant aerosol and water ions, both of which have a sterilization effect. Even if the concentration of the disinfectant is low, it can ensure a sufficient sterilization effect. Therefore, a disinfectant with a low concentration can be used to prevent corrosion of items in the space where the sterilization device is located; on the other hand, the atomizing element 200 releases the disinfectant aerosol into the installation cavity 120 where the nano water ion generator 300 is located, which can increase the humidity of the installation cavity 120, so that the nano water ion generator 300 can obtain sufficient moisture, and reduce the influence of external humidity on the use effect of the nano water ion generator 300. In summary, the sterilization device provided by the embodiment of the utility model is not easy to cause corrosion of items in the space, is less affected by environmental conditions, has a wide range of application scenarios, and has a good sterilization effect.

[0035] Further, refer to Figure 2 and Figure 6 , the sterilization device also includes an electric control component 500, which is located in the installation cavity 120, and the electric control component 500 is electrically connected to the atomizer 200, the nano water ion generator 300 and the fan 400. The electric control component 500 can realize the control of the atomizer 200, the nano water ion generator 300 and the fan 400 to adapt to different usage requirements. For example, a humidity sensor can be set in the electric control component 500, and the humidity sensor is used to obtain the humidity of the space where the sterilization device is located. When the humidity is lower than the preset value, the electric control component 500 controls the atomizer 200 to increase the power to further increase the humidity in the installation cavity 120, so as to ensure that the nano water ion generator 300 can obtain enough water, thereby ensuring that the nano water ion generator 300 can generate water ions normally; buttons, knobs and other operating components can also be set in the electric control component 500, and the user can control the working mode of the atomizer 200, the nano water ion generator 300 and the fan 400 through the operating components according to actual needs.

[0036] In some embodiments, the disinfectant is a hypochlorous acid solution. Hypochlorous acid can act on cell walls and virus shells, and can also penetrate into the interior of bacteria or viruses, and react with organic macromolecules such as proteins, nucleic acids, and enzymes inside bacteria or viruses to kill pathogenic microorganisms. However, hypochlorous acid is easy to decompose in the solution and is not easy to store for a long time. In order to ensure the bactericidal effect of hypochlorous acid, reference Figure 2 The sterilization device further includes an electrode sheet 700, which is installed inside the liquid storage chamber 110, and the electric control component 500 is electrically connected to the electrode sheet 700. Before the sterilization device is started, a sodium chloride solution can be added to the liquid storage chamber 110, and then the electrode sheet 700 is energized. The electrode sheet 700 can electrolyze the sodium chloride aqueous solution to form a hypochlorous acid solution, and the reaction formula is as follows:

[0037] 2NaCl+2H2O→Cl2↑+H2↑+2NaOH

[0038] Cl2+H2O→HCl+HClO

[0039] After the preparation of hypochlorous acid is completed through the above process, the atomizing element 200 is started again to atomize the hypochlorous acid solution in the liquid storage chamber 110 into hypochlorous acid aerosol. The electrode sheet 700 is arranged in the liquid storage chamber 110, so that hypochlorous acid can be prepared on site before the sterilization device is used for sterilization, which is conducive to preventing hypochlorous acid from decomposing due to long-term storage and then losing its sterilization ability, and can ensure the sterilization effect of hypochlorous acid.

[0040] During the electrolysis of sodium chloride aqueous solution, the electrode sheet 700 energizes the liquid, and the atomizer 200 directly contacts the energized liquid and may be damaged. Figure 2 and Figure 3 The liquid storage chamber 110 includes a first liquid storage space 111, a second liquid storage space 112 and a communication port 113. The second liquid storage space 112 is connected to the first liquid storage space 111 through the communication port 113. The atomization port 130 is connected to the first liquid storage space 111. The electrode sheet 700 is installed inside the second liquid storage space 112. Figure 2 The sterilization device further includes an electric control valve 600, which is installed at the communication port 113. The electric control component 500 is electrically connected to the electric control valve 600, and the electric control component 500 can control the electric control valve 600 to open or close.

[0041] Before the sterilization device is started, the electric control valve 600 is closed, the first liquid storage space 111 is isolated from the second liquid storage space 112, a sodium chloride solution is added to the second liquid storage space 112, and then the electrode sheet 700 is energized, and the electrode sheet 700 electrolyzes the sodium chloride aqueous solution in the second liquid storage space 112 to form a hypochlorous acid solution; after the preparation of hypochlorous acid is completed, the electric control valve 600 is opened, and the hypochlorous acid solution in the second liquid storage space 112 flows into the first liquid storage space 111 through the connecting port 113 and contacts the atomizer 200; then the atomizer 200 is started, and the atomizer 200 atomizes the hypochlorous acid solution in the first liquid storage space 111 into hypochlorous acid aerosol.

[0042] Through the above arrangement, during the electrolysis of the sodium chloride aqueous solution, since the electrically-controlled valve 600 is closed, the first liquid storage space 111 and the second liquid storage space 112 are isolated, and the liquid in the second liquid storage space 112 will not contact the atomizer 200. Therefore, the energized liquid will not affect the atomizer 200, which is beneficial to reduce the possibility of damage to the atomizer 200 and increase the service life of the atomizer 200.

[0043] Furthermore, a filter is provided at the communication port 113 or inside the electric control valve 600 , and the filter can filter the liquid entering the first liquid storage space 111 from the second liquid storage space 112 to prevent impurities in the liquid from entering the first liquid storage space 111 and affecting the normal operation of the atomizer 200 .

[0044] Further, refer to Figure 1 and Figure 2 The housing 100 includes a bottom shell 160, a main body 170 and a top cover 180, the liquid storage chamber 110 is defined between the top cover 180 and the main body 170, the installation chamber 120 is defined between the bottom shell 160 and the main body 170, and the main body 170 has an atomization port 130. In some specific embodiments, refer to Figure 2 The atomizer 200 can be fixed to the atomizer port 130 of the main body 170 through the fixing cover 210. The split housing 100 is easy to manufacture and install, and the liquid storage chamber 110 is defined between the top cover 180 and the main body 170, and the installation chamber 120 is defined between the bottom shell 160 and the main body 170. The space for storing liquid and the space for installing other components can be separated by the main body 170 to prevent the liquid from affecting the operation of other components.

[0045] The electronic control component 500 may use a circuit board with electrical components and printed circuits on its surface. It should usually work in a relatively dry environment to reduce the failure rate of the electronic control component 500. The atomizer 200 will produce a disinfectant aerosol, which contains a lot of water. Based on this, refer to Figure 2 , Figure 4 and Figure 5The installation cavity 120 includes a first cavity 121, a second cavity 122 and a wiring hole 123. The first cavity 121 and the second cavity 122 are connected through the wiring hole 123. The atomizer 200, the nano water ion generator 300 and the fan 400 are all located in the first cavity 121. The electric control component 500 is located in the second cavity 122. The wiring of the atomizer 200, the nano water ion generator 300 and the fan 400 can be electrically connected to the electric control component 500 through the wiring hole 123. The disinfectant aerosol is released in the first cavity 121, and the first cavity 121 and the second cavity 122 are separated from each other. The two are only connected in the wiring hole 123 for wiring, which is conducive to reducing the aerosol entering the second cavity 122, thereby reducing the humidity of the space where the electric control component 500 is located, so as to reduce the failure rate of the electric control component 500.

[0046] Further, refer to Figure 2 and Figure 4 , the second cavity 122 is located at the side of the liquid storage cavity 110, and the sterilization device further includes an operation panel 800, which is connected to the housing 100 and corresponds to the second cavity 122. Specifically, in some embodiments, the operation panel 800 is connected to the main body 170 and covers the second cavity 122, which can not only cover the second cavity 122, but also facilitate the electrical connection between the operation panel 800 and the electric control component 500; Figure 6 The electric control component 500 is electrically connected to the operation panel 800. Mechanical buttons, touch buttons, display lights, etc. can be set on the operation panel 800 for the user to control the sterilization device, obtain the current status of the sterilization device, etc.

[0047] Further, refer to Figure 2 The housing 100 further includes an operation cover 190 , the bottom housing 160 has an operation window 161 , the operation panel 800 is at least partially exposed from the operation window 161 , the operation cover 190 covers the operation window 161 , and the operation cover 190 can protect the operation panel 800 .

[0048] Further, refer to Figure 2 , the air inlet 140 is located at the lower part of the housing 100, and the air outlet 150 is located at the upper part of the housing 100. Specifically, in some embodiments, the air inlet 140 is located on the bottom shell 160, and the air outlet 150 is located on the top cover 180. The airflow with water ions and disinfectant mist can be discharged from the top of the sterilization device to the external environment, and the airflow has an upward initial velocity, which can be better dispersed in the space where the sterilization device is located; refer to Figure 1 , Figure 2 and Figure 4The first cavity 121 includes a accommodating area 1211 and an air outlet channel 1212, the air outlet channel 1212 is connected to the accommodating area 1211, the fan 400 is located in the accommodating area 1211, the nano water ion generator 300 is located in the accommodating area 1211 or the air outlet channel 1212, the atomizer 200 is located in the accommodating area 1211 or the air outlet channel 1212, the accommodating area 1211 is located below the liquid storage chamber 110, the air outlet channel 1212 extends from the lower part of the shell 100 to the upper part of the shell 100, and the airflow generated by the fan 400 enters the interior of the shell 100 from the air inlet 140. It needs to pass through the air outlet channel 1212 in a direction generally from bottom to top before it can be discharged from the air outlet 150. In the air outlet channel 1212, the airflow and water ions and disinfectant aerosol can be more fully mixed, so that the water ions and the disinfectant aerosol can be better discharged into the space where the sterilization device is located to disinfect the space.

[0049] Reference Figure 1 , Figure 4 and Figure 5 A curved surface 1213 is provided at the corner of the air outlet channel 1212. The curved surface 1213 can guide the airflow and reduce the resistance of the airflow flowing in the air outlet channel 1212, so that water ions and disinfectant mist can be released to the external environment more smoothly.

[0050] Further, refer to Figure 1 Part of the main body 170 is exposed from between the top cover 180 and the bottom shell 160 to expose the outer wall of the liquid storage chamber 110. In the scheme of using hypochlorous acid solution as the disinfectant, since the hypochlorous acid solution is easily decomposed under the action of light, the main body 170 can be made of a translucent material, which can not only reduce the light irradiated on the liquid, but also allow the user to observe the liquid level in the liquid storage chamber 110, so that the user can add liquid in time.

[0051] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
