Description

Technical Field

[0001] This utility model relates to the technical field of air purification, and in particular to a structure for deodorizing and sterilizing indoor air. Background Technology

[0002] In the current field of indoor air treatment, various technologies have been developed to address the needs of odor removal and sterilization. These technologies can be mainly divided into two categories: active odor removal and sterilization, and passive contact technologies. Active odor removal and sterilization technology relies on the self-diffusion of specific components or materials to ensure full contact with indoor air, thereby achieving sterilization and odor removal effects. The significant advantage of this type of technology lies in its proactiveness and high efficiency, enabling it to quickly respond to and process harmful substances and odors in indoor air. However, active odor removal and sterilization technologies also face significant challenges. Since most of these technologies rely on strong oxidizing materials, these materials may oxidize and corrode other indoor facilities during use, and even pose a potential threat to human health. Therefore, it is often difficult to achieve human-machine coexistence with these technologies, that is, to ensure both effective sterilization and odor removal while ensuring harmlessness to the human body.

[0003] Ozone sterilization technology, as a type of active deodorization and sterilization technology, has advantages such as broad spectrum, fast reaction speed, and ease of preparation, and therefore has been widely used in industries and animal husbandry. Ozone can quickly kill a variety of bacteria and viruses, effectively improving air quality. However, ozone's strong oxidizing properties also bring problems that cannot be ignored. In indoor environments, ozone concentration control is extremely critical. If the concentration is too low, the sterilization and deodorization effect will be limited; if the concentration is too high, it may exceed national standards and have a negative impact on human health. Therefore, how to reasonably control ozone to reduce its impact on human health while ensuring sterilization and deodorization effects has become a technical challenge that urgently needs to be solved in the field of indoor air treatment.

Figure 2 This is a cross-sectional view of the structure of the present invention for deodorizing and sterilizing indoor air. Figure 3 This is a schematic diagram of the structure of a diverter for deodorizing and sterilizing indoor air according to the present invention. Figure 4 This is a partial structural diagram of a structure for deodorizing and sterilizing indoor air according to the present invention, as shown below. Figures 1-4As shown, a preferred embodiment of an indoor air deodorization and sterilization structure is illustrated, comprising: a housing 1, a purification channel 11 on the housing 1, and a fan 4, an ozone generator 5, a diverter 6 and an ozone removal filter 7 arranged sequentially in the purification channel 11, wherein the diverter 6 includes a first diverter plate 61, and the side of the first diverter plate 61 near the ozone generator 5 is set as a conical surface.

[0028] In this embodiment, indoor air enters the purification channel 11 through one opening of the fan 4 and flows toward the other opening of the purification channel 11. During the flow, the ozone generator 5 releases ozone and mixes with the air to deodorize and sterilize. The air mixed with ozone is then filtered by the ozone removal filter 7 and finally discharged from the other opening of the purification channel 11.

[0029] In this embodiment, ozone generator 5 releases ozone to deodorize and sterilize the air, and then the ozone in the air is filtered through ozone removal filter 7, which can effectively avoid the negative impact of excessive ozone concentration on human health and improve the safety of use.

[0030] In this embodiment, in order to fully mix the ozone released by the ozone generator 5 with the air and improve the deodorization and sterilization effect of the air, a diverter 6 is set between the ozone generator 5 and the ozone removal filter 7. When the ozone is blown toward the first diverter plate 61, it is diverted to all directions under the action of the conical surface of the first diverter plate 61 and fully mixed with the air passing through the first diverter plate 61.

[0031] Furthermore, as a preferred embodiment, in order to further improve the mixing effect of ozone and air, the diverter 6 also includes a second diverter plate 62, which is disposed between the first diverter plate 61 and the ozone filter.

[0032] Furthermore, as a preferred embodiment, both the first diversion mesh plate 61 and the second diversion mesh plate 62 have a number of air holes, through which the mixture of air and ozone passes through the air holes and then through the first diversion mesh plate 61 / second diversion mesh plate 62.

[0033] Furthermore, as a preferred embodiment, the ozone generator 5 is a high-voltage discharge ozone generator 5. The high-voltage discharge ozone generator 5 is an existing mature structure, and its specific principle and structure will not be described in detail here.

[0034] Furthermore, as a preferred embodiment, an air inlet filter 3 is also installed in the purification channel 11. The air inlet filter 3 is located on the side of the fan 4 away from the ozone generator 5. The purpose of installing the air inlet filter 3 is to filter out large particulate impurities, hair, and willow catkins in the air.

[0035] Furthermore, as a preferred embodiment, a mounting plate 8 is installed inside the purification channel 11. The mounting plate 8 has ventilation holes, and the fan 4 is installed on the mounting plate 8, with the air outlet of the fan 4 connected to the ventilation holes.

[0036] Furthermore, as a preferred embodiment, the housing 1 is a rectangular housing 1 with openings at both ends, and a purification channel 11 is formed inside the housing 1.

[0037] Furthermore, as a preferred embodiment, the bottom of the housing 1 has a support frame 2.

[0038] Furthermore, as a preferred embodiment, foot pads 21 are provided at the four corners of the bottom of the support frame 2.

[0039] Furthermore, as a preferred embodiment, the ratio of the area of ​​the ozone deodorization filter 7 to the wind speed of the fan 4 should be >0.01 (m). 2 ): 2 (m / s).

[0040] In this embodiment, the ozone removal filter 7 is a mature existing technology. It can use materials with a large surface area and small pores as the filter medium, such as aluminum-zinc alloy and aluminum honeycomb. These materials have a high ozone adsorption capacity. When ozone in the air passes through the filter, ozone molecules are adsorbed onto the surface of the filter. By increasing the surface area and porosity of the filter material, the contact area between ozone and the filter material can be greatly increased, thereby improving the adsorption effect. Furthermore, the ozone removal filter 7 not only removes ozone through physical adsorption, but also uses chemical reactions to further decompose ozone molecules. For example, reducing agents such as activated carbon, manganese dioxide, or active molecular catalysts loaded on a carrier (such as copper wire mesh) are added to the filter. These reducing agents can chemically react with the ozone molecules adsorbed on the filter, decomposing them into harmless oxygen (O2). Specifically, when ozone molecules come into contact with the reducing agent on the filter surface, a catalytic reduction reaction occurs. In this process, ozone molecules are decomposed into oxygen molecules, and the ozone in the air treated by the filter is effectively removed.

[0041] Furthermore, the ozone concentration generated by ozone generator 5 is controlled at 200-300 ppb.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
