Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to Fig. 2, it is a first embodiment of the novel air cleaning device. This first embodiment includes a shell 2 surrounding a configuration space 20, a guide fan 3 installed in the configuration space 20, and a The ion generating module 4 installed in the configuration space 20 . What should be explained first is that, during actual implementation, the first embodiment can be fixed on the air intake sources such as ventilation windows, transoms, air-conditioning outlets, etc., or even ventilation ducts, air-conditioning outlets, etc. The intermediary position in the pipeline, etc., so that the air is cleaned in advance before it is introduced into a specific space.

Referring to Fig. 2 and Fig. 3 at the same time, the configuration space 20 has an air inlet 201 and an air outlet 202 respectively located at the front side and the rear side along an airflow direction D, that is, the casing 2 is generally a through shape along the airflow direction D. The housing is preferably made of transparent acrylic material. In addition to being easy to observe the configuration space 20, it can also reduce the overall weight of the first embodiment and facilitate deployment and use anywhere.

The guide fan 3 is suitable for introducing the airflow into the configuration space 20 from the air inlet 201, and then leading out from the air outlet 202, so that the flow rate can match the configuration space 20 volume, or choose according to the volume of wind you want to blow out. Wherein, the guide fan 3 preferably can use a low-voltage direct current power supply, so as to facilitate cooperation with a portable power supply, a vehicle power supply, or even a simple solar power supply, so as to achieve the effect of being convenient to use anywhere. In addition, the guide fan 3 can also use a silent fan to reduce adverse effects on the surrounding living environment during operation. It should be noted that if the guide fan 3 must be arranged adjacent to the air inlet 201 due to the overall specification design of the casing 2, the casing 2 can be provided with a block to block the air inlet 201 and form a There are a plurality of guard nets 29 with through slots 290 communicating with the configuration space 20 to prevent users from touching the guide fan 3 directly, thereby ensuring safe use.

Referring to FIG. 4 , the ion generating module 4 includes a negative ion generator 41 , a positive ion generator 42 , and a switcher 43 connected to the negative ion generator 41 and the positive ion generator 42 . Wherein, the switch 43 is used to switch the ion generating module 4 between a negative ion state in which the negative ion generator 41 operates and a plasma state in which the negative ion generator 41 and the positive ion generator 42 operate together. Specifically, the switch 43 can be a toggle switch, which can be operated manually, remotely, etc., to select only the negative ion generator 41 to operate to generate negative ions, or to make the negative ion generator 41 and the positive ion The generator 42 operates simultaneously to generate negative ions and positive ions, that is, a plasma mechanism in which a neutralizing discharge is generated between positive and negative ions.

Referring again to Fig. 2 and coordinating Fig. 4, in the state of negative ions, since the negative ion generator 41 is arranged on one side of the guide fan 3 close to the air outlet 202, and A disturbance space is separated from the guide fan 3, so that when the negatively charged ions are generated by the discharge, they can be fully attached to the air taken in at the front end, and then led out from the air outlet 202 later. Then, since the earth can be regarded as an entity with infinite positive charges, the negative ions drawn out from the air outlet 202 will move towards the ground due to the attraction of positive and negative charges, except that the suspended particles with the negative ions in the air are adsorbed to the ground, thereby accelerating the settling of suspended particles. Among them, besides dust, the suspended particles, bacteria, mold spores, viruses, etc. suspended in the air will also settle to the ground due to the same mechanism, so as to achieve the effect of cleaning the air. In addition, if the air introduced into the configuration space 20 contains bacteria or viruses, when the bacteria and viruses are positively charged, they may be directly eliminated by neutralizing discharge when they come into contact with the negative ions, thereby achieving The effect of killing germs.

In addition, when the ion generating module 4 is in the plasma state, the negative ion generator 41 and the positive ion generator 42 operate simultaneously, so that negatively charged ions and positively charged ions can be generated simultaneously. In this way, some of the bacteria and viruses in the air will be positively charged and partly negatively charged, and then attract each other to generate a neutralizing discharge. Therefore, the structure of bacteria and viruses can be destroyed through electric energy, and the goal of killing bacteria can be achieved. Effect. In addition to targeting germs, harmful molecules such as formaldehyde in the air can also effectively destroy their molecular structure through the plasma mechanism.

It is worth noting that, considering that if the positively charged ions are directly output from the air outlet 202, it may cause harm to people, pets, or even specific objects, so if The first embodiment is mainly used in consideration of switching to the plasma state, so another implementation style shown in Figure 5 in the first embodiment can be configured to be detachably arranged on the air outlet 202, and used for The barrier net 6 that blocks excessive positive ions maintains the use safety of the first embodiment in response to the use of the plasma state.

Referring to Fig. 6, it is a second embodiment of the novel air cleaning device. The difference between the second embodiment and the first embodiment is that the second embodiment also includes a second embodiment which is arranged on the guiding fan 3 close to the inlet. On one side of the tuyere 201, the filter material 5 is separated from the guide fan 3 by a buffer distance. The filter material 5 is preferably a fiber filter cotton that simply filters dust, or activated carbon cotton with deodorizing and sterilizing effects, or even one that contains metal ions such as silver ions and copper ions that have a bactericidal effect. Synthetic cotton. It should be noted that due to the fine pore structure of the filter material 5, it is bound to produce a certain wind resistance for the air intake of the configuration space 20. In order to ensure smooth air intake and buffer the air entering the configuration space 20, the The filter material 5 needs to be separated from the guiding fan 3 by the buffer distance, so as to ensure the normal operation of the whole. Except for the related configuration and filtering effect of the aforementioned filter material 5 , the second embodiment can achieve the same effect as the first embodiment.

Referring to Fig. 7, it is a third embodiment of the new air cleaning device. The difference between this third embodiment and the first embodiment and the second embodiment is that the housing 2 includes a body portion 21, a plurality of forming The connecting portion 22 on the top of the main body portion 21, and a plurality of connecting portions 23 formed on the bottom of the main body portion 21 and used for respectively assembling with the connecting portions 22 of another air cleaning device. Specifically, each of the connecting parts 22 can These are the screws used to assemble the body part 21, and each of the assembling parts 23 can be formed with a groove corresponding to the shape of the screw at the bottom, and can be used as a protrusion of the supporting structure. However, in actual implementation, as long as each connecting portion 22 and the individual assembling portion 23 can be ensured to be connected with each other to achieve positioning requirements, it is not limited to the aforementioned implementation. By virtue of the connection between the connecting parts 22 and the connecting parts 23 , an appropriate number of the air cleaning devices of the present invention can be combined according to the usage requirements of the environment, or such as the air inlets of windows.

For specific implementation, as shown in FIG. 8 , through the interconnection of the connection parts 22 and the assembly parts 23, the third embodiment is switched to the negative ion state and the air outlet 202 is fully opened, and The third embodiment that is switched to the plasma state and the air outlet 202 is equipped with the barrier net 6 is matched with each other, so as to meet more diversified usage requirements. Wherein, in the implementation situation as shown in Figure 8, the third embodiment switched to the negative ion state and the other two third embodiments switched to the plasma state have the air outlet 202 facing in different directions. Situations are superimposed to avoid mutual restraint of different air processing mechanisms. It should be further explained that when the third embodiment is stacked with three layers as shown in Figure 8, the ground area occupied is only within the range of a single third embodiment, so even if multiple layers are stacked, a large number of It will not occupy too much area, which is more conducive to the proper application of limited space and flexible configuration.

It is worth noting that the first implementation of the novel air cleaning device In the first embodiment, the second embodiment, and the third embodiment, multiple air cleaning devices of the present invention can be connected in series through the air ducts in response to the treatment requirements, so that multiple treatment mechanisms can be exerted simultaneously, and a more effective germ killing effect can be exerted. kill effect.

To sum up, the new air cleaning device can be flexibly configured in response to the needs of use and environmental conditions, so that the electrically dissociative ions generated by the configured ion generating module 4 can truly interact with suspended particles, bacteria, viruses, and harmful molecules, fully Play the expected effect of electrical ionization treatment. Therefore, can really reach the purpose of this novelty.

But the above-mentioned ones are only embodiments of the present invention, and should not limit the scope of implementation of the present invention with this. All simple equivalent changes and modifications made according to the patent scope of the present application and the content of the patent specification are still within the scope of the present invention.
