DETAILED DESCRIPTION

[0026] In order to make the technical scheme of the present application clearer, the following will make further detailed description of the present application in combination with the drawings and specific embodiments.

[0027] Embodiment 1

[0028] In order to make the technical scheme of the present application clearer, the following will make further detailed description of the present application in combination with the drawings and specific embodiments.

[0029] In order to make the technical scheme of the present application clearer, the following will make further detailed description of the present application in combination with the drawings and specific embodiments.

[0030] In order to make the technical scheme of the present application clearer, the following will make further detailed description of the present application in combination with the drawings and specific embodiments. Figures 1-6 An air disinfection purifier, comprising a shell 1, an ion plasma reactor 2 and a fan 3 arranged in the shell 1, wherein the fan 3 is arranged on one side of the ion plasma reactor 2 and is used to suck the gas to be disinfected through the ion plasma reactor 2.

[0031] The ion body reactor 2 includes N negative plates 4 connected to a negative electrode and alloy plates 5 connected to a positive electrode, where N is an integer greater than 1, and gaps exist between the negative plates 4 and the alloy plates 5 to form a discharge area and pass through the gas that needs to be disinfected.

[0032] Specifically, the fan 3 inhales air, which is introduced into the ion body reactor 2, rapidly decomposes and eliminates harmful air gases, and clean air is blown out through the fan 3. Through voltage dielectric barrier discharge, low-voltage discharge is achieved. Plasma technology can generate a large number of non-equilibrium positive and negative oxygen ions. The energy consumption of this reaction process is relatively low, which can significantly reduce energy costs during long-term operation of the equipment, and is especially suitable for use in homes and commercial places.

[0033] The discharge area of the ion body reactor enters the purification process, and the ion body reactor is internally provided with N negative plates 4 and alloy plates 5 installed between adjacent negative plates 4. The negative plates 4 are connected to a negative electrode, and the alloy plates 5 are connected to a positive electrode. Through this polarity setting, an electric field is formed between the negative plates 4 and the alloy plates 5. As the electric field strength increases, the discharge area produces ionization effect to ionize or generate plasma to destroy the cell structure or DNA of pathogens such as bacteria and viruses, achieving the effect of air disinfection. Through the uniform linear structure, stable discharge is achieved, which optimizes air flow and reduces the burden on the heating and ventilation fan 22, thereby reducing energy consumption. This discharge mode can provide high uniformity and strength to ensure that the gas is fully ionized and disinfected when passing through the ion body reactor, and solves the problem of corona generated by polarization of air particles in the prior art.

[0034] Gaps are formed between the negative plates 4 and the alloy plates 5, which allows the formation of a discharge area between the electrodes. The action of the electric field activates the molecules in the air, thereby producing ionization effect to kill bacteria and viruses in the air.

[0035] In some specific embodiments, the two ends of the negative plates 4 and the alloy plates 5 are respectively connected to the reactor support 6.

[0036] Specifically, the reactor support 6 provides structural support to ensure that the negative plates 4 and the alloy plates 5 remain stable during operation and are not moved or shaken due to air flow or other factors. This helps to maintain the distance between the electrodes, thereby ensuring the uniformity of the electric field and the effectiveness of the discharge.

[0037] In some specific embodiments, the housing 1 includes an air inlet mesh plate 7 and an air outlet mesh plate 8. The air inlet mesh plate 7 is arranged on the side of the ion body reactor 2 away from the fan 3, and the air outlet mesh plate 8 is arranged on the side of the fan 3 away from the ion body reactor 2.

[0038] Specifically, the air inlet mesh plate 7 is located on the side of the plasma reactor away from the fan 2, designed as the gas inlet, through which the external air is sucked into the equipment, and the design of the mesh plate 7 can effectively prevent large particles from entering the plasma reactor 2, ensuring that the entering gas is relatively clean, thereby improving the purification effect; the air outlet mesh plate 8 is arranged on the side of the fan 3 away from the plasma reactor, serving as the gas outlet, through which the air treated by the plasma reactor is discharged, ensuring that the purified air can be smoothly released into the environment, and the reasonable arrangement of the air inlet and outlet mesh plates 8 helps to form a good air circulation, enhancing the overall performance of the equipment.

[0039] In some specific embodiments, a filter screen 9 is arranged between the air inlet mesh plate 7 and the plasma reactor 2.

[0040] Specifically, the filter screen 9 is used to capture large particles in the air, such as dust, pollen, and smoke, which can prevent these impurities from entering the plasma reactor, thereby protecting the internal components and prolonging the service life of the equipment. By pre-filtering impurities in the air, the filter screen 9 can ensure that the air entering the plasma reactor is cleaner, improving the efficiency of killing bacteria and viruses during ionization. Therefore, the air flow through the filter screen is smooth and uniform, which can protect the air conditioning system, reduce system energy consumption, reduce noise, and is suitable for quiet public and home environments.

[0041] In some specific embodiments, the filter screen 9 is folded into a high-strength cardboard.

[0042] In some specific embodiments, an ozone decomposition filter plate 10 is arranged between the fan 3 and the air outlet mesh plate 8.

[0043] Specifically, the main function of the ozone decomposition filter plate 10 is to remove ozone that may be generated in the plasma reactor, but it is harmful to the human body at high concentrations. Therefore, effective removal of ozone is crucial to ensure air quality. By removing ozone, the filter plate can improve the quality of the discharged air, making it safer and more suitable for human respiration, which is particularly important for closed spaces such as homes and offices.

[0044] In some specific embodiments, a controller 11 is arranged on one side of the fan 3.

[0045] Specifically, the controller 11 also includes an existing controller circuit, which includes a digital control circuit with an oscillator, an error amplifier, and a PWM comparator. The system can convert the control signal into a digital control current, accurately adjusting the width of the high-voltage pulse to meet the needs of specific applications.

[0046] In some specific embodiments, the motor of the fan 3 is a brushless motor.

[0047] Specifically, the noise generated by the fan 3 during operation is low, which is particularly important for places that require a quiet environment (such as a bedroom or office), helps to improve user experience, and brushless motors have higher energy conversion efficiency than brushed motors, which means that under the same power, brushless motors can provide stronger wind power and improve air circulation effect. Brushless motors usually have a longer service life due to the absence of carbon brush wear, which reduces the frequency of maintenance and replacement and reduces long-term use costs.

[0048] In some specific embodiments, the shell 1 further comprises a support top plate 12 and a support bottom plate 13, which are respectively arranged on the upper side and the lower side of the plasma reactor 2 and the fan 3.

[0049] In some specific embodiments, the shell 1 further comprises two first fixing plates 14, which are arranged on the two sides of the plasma reactor 2 and the fan 3.

[0050] In some specific embodiments, the shell 1 further comprises two second fixing plates 15, and the first fixing plate 14 is arranged on the two sides of the air inlet mesh plate 7 and the air outlet mesh plate 8.

[0051] In some specific embodiments, the shell 1 is an alloy shell, which is more simple, beautiful, corrosion-resistant, waterproof, anti-aging, durable, and cost-effective.

[0052] Specifically, the simple structure improves assembly efficiency, and the alloy shell material can reduce damage and improve safety.

[0053] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
