Description
Technical Field
[0001] The present invention relates to the technical field of air purification equipment, and in particular to an improved plasma generating system. Background Art
[0002] The economic development of Chinese society has promoted the improvement of consumers' material life. Coupled with the increase in industrial production and fuel vehicles, people have begun to pay attention to air health issues.
[0003] In terms of air quality control, the most widely used device is a household air purifier.
[0004] This type of purifier is generally required to be relatively small in size and will not take up too much home space; it can be used in closed home spaces and non-open-air public venues, providing a steady supply of fresh air to people in the space.
[0005] In existing air purifiers, the mainstream functional component is a plasma generator, which ionizes the air and then sterilizes and reduces dust, thereby achieving the air purification function. However, existing plasma generators have low efficiency in plasma generation and diffusion, resulting in relatively low air purification efficiency. In addition, plasma generators consume high energy, resulting in wasteful resources. A plasma generator that can effectively improve the purification efficiency of plasma air purifiers while reducing actual power consumption is currently in high demand. Summary of the Invention
[0006] The technical problem to be solved by the present invention is to provide an improved plasma generating system, which can effectively solve the problem of overly single functional structure of existing market products, improve the product's ordinary air ionization efficiency and ionized air exchange efficiency, increase the ionized air diffusion speed, and improve the energy utilization rate of the air purifier.
[0007] The following technical solution is provided to solve this problem: an improved plasma generating system, comprising an outer shell and a plasma with an external high-frequency voltage, the plasma comprising an insulating tube and a metal wire spirally wound on the insulating tube, the outer shell comprising a accommodating cavity for placing the plasma, a accommodating cavity wall provided with an airflow channel, and a filter sleeve provided on the outside of the accommodating cavity wall, a circulating airflow guiding device is provided at the rear end of the outer shell, the circulating airflow guiding device comprises a dredging cavity and a dredging fan clamped in the dredging cavity, the dredging fan is a two-way guide structure, the dredging fan comprises an outer ring dredging fan blade group and a power shaft provided on the inner side of the dredging fan blade group, the power shaft is a cylindrical structure with a hollow middle portion, and an air suction fan blade group is provided in the inner cavity of the power shaft. The multi-layer protective structure of the filter sleeve effectively improves the purity of the air during the plasma ionization process, prevents foreign particles from entering the accommodating cavity and affecting the ionization efficiency and the working life of the plasma, and the circulating airflow diversion device greatly improves the output of the airflow and the external ionization uniform diffusion efficiency, thereby improving the actual ionization effect, diverting the self-circulation inside and outside the fan, further improving the air ionization distribution efficiency around the equipment, and improving the actual purification and sterilization efficiency.
[0008] As an improvement, the rear end of the dredging fan is provided with a motor, and the output shaft of the motor is provided with two or more transmission brackets, and the ends of the transmission brackets are connected to the power shaft. A plurality of transmission bracket structures are provided to transmit power between the motor and the dredging fan. While the power is effectively transmitted, the gaps between adjacent transmission brackets realize the airflow circulation channel between the dredging fan blade group and the suction fan blade group, thereby realizing the circulation between the outside air and the internal ionized airflow. The large-area dredging fan blade group effectively draws the outside gas into the accommodating cavity through the filter sleeve for ionization and then guides it out to the outside to provide the main power, further improving the circulation efficiency of the ionized airflow around the plasma and the ordinary air, thereby improving the overall purification effect of the equipment. The relatively small-area suction fan blade group forms an airflow circulation at both sides of the dredging fan and the dredging fan blades. The suction fan blade group mixes the small amount of airflow inhaled with the ionized air and then guides it out to the outside by the dredging fan. The mixed air after discharge has been partially diluted, and the ionized air flowing out of the outside is more quickly evenly mixed. The ionization distribution effect of the outside air is achieved in advance and quickly pre-fusion on both sides of the dredging fan, thereby improving the actual working efficiency of the equipment.
[0009] As an improvement, a guide hole is provided between the diversion cavity and the accommodating cavity, and a protective filter is provided outside the guide hole. The guide hole facilitates the outlet of the airflow, and the protective filter prevents particles that may be present in the diversion cavity from entering the accommodating cavity.
[0010] As an improvement, the drainage cavity port card is equipped with a drainage plate, which is attached to the outer end of the drainage fan. The drainage plate is provided with a drainage grille, a connecting portion is provided in the middle of the drainage plate, and a connecting frame is provided on the outer edge of the drainage plate. The drainage grille is arranged between the connecting portion and the connecting frame. The provision of the drainage grille achieves a uniform, stable and efficient airflow pattern, further effectively preventing the accumulation of high-concentration plasma air that cannot be dispersed and utilized, and improving energy conversion efficiency.
[0011] As an improvement, a spiral retaining groove is provided on the outer wall of the insulating tube, and the metal wire on the insulating tube is wound in the spiral retaining groove. This is suitable for limiting and locking, ensuring the stability of the metal wire and preventing it from slipping, thereby effectively improving the functional stability and service life of the plasma.
[0012] As an improvement, a snap-in groove is provided on the inner wall of the plasma generating chamber, a snap-in plate corresponding to the snap-in groove is provided on the guide plate, the snap-in plate is arranged perpendicular to the inner side surface of the guide plate, the snap-in groove is an L-shaped groove, and the snap-in plate is an L-shaped plate corresponding to the snap-in groove. The outer peripheral surface of the drainage fan rests on the inner wall of the plasma generating chamber, and then an L-shaped clamping groove is set on the inner wall of the ion generating chamber. During assembly, the L-shaped clamping plate is inserted into the clamping groove and then rotated to one side to realize the insertion of the plug-in plate at the bottom and the groove, respectively realizing circumferential and longitudinal limiting, ensuring that the drainage plate is stably clamped in the plasma generating chamber and just clamps the drainage fan in the plasma generating chamber. The inner wall of the plasma generating chamber and the inner wall of the clamping plate simultaneously cover and rest against the outer peripheral surface of the drainage fan, realizing circumferential comprehensive covering, the various structural parts are compactly connected, the amplitude of the working process is reduced, and it is not easy to cause collision damage to the functional components, thereby improving the working life of the equipment; when the drainage plate needs to be disassembled, it is first rotated circumferentially to one side, the plug-in plate at the lower end of the clamping plate is unscrewed and then pulled out longitudinally before it can be disassembled. It is not easy to disengage under normal non-human operation and has good connection stability.
[0013] As an improvement, the chamber wall is provided with multiple airflow channels, with at least two channels evenly spaced circumferentially and at least five channels arranged axially. The multiple airflow channels are evenly spaced circumferentially and axially to ensure stable airflow during the ionization process and continuous, efficient operation of the device.
[0014] As an improvement, the filter sleeve is constructed from at least three layers of woven cotton mesh. The innermost layer of the woven cotton mesh is provided with a velvet filter cushion on its inner side. The filter cushion is designed as a raised velvet fabric and is positioned at the end of the airflow channel. This effectively enhances the filtration strength of the airflow channel, while the multi-layered woven cotton mesh outer structure effectively isolates foreign particles. The overall weight is lightweight and the filtration efficiency is high. This targeted improvement in filtration material reduces the actual material usage and saves manufacturing costs.
[0015] The beneficial effects of this invention are: the multi-layer protective structure of the filter sleeve effectively improves the purity of the air during the plasma ionization process, prevents foreign particles from entering the accommodating cavity and affecting the ionization efficiency and the working life of the plasma, and the circulating airflow guiding device greatly improves the output of the airflow and the external ionization uniform diffusion efficiency, improves the actual ionization effect, guides the self-circulation inside and outside the fan, further improves the air ionization distribution efficiency around the equipment, and improves the actual purification and sterilization efficiency.
