Description

TECHNICAL FIELD

[0001] The utility model relates to air purification technical field, concretely relates to a kind of arrangement structure of improving negative ion air purifier negative ion concentration. BACKGROUND

[0002] Air purifier with negative ion function usually generates air negative ion through negative ion generator.Negative ion generator is a kind of device generating air negative ion, which converts input direct current or alternating current into alternating high voltage through full-coupled transformer after oscillation circuit, and then obtains direct current high voltage through rectifier filter circuit.The direct current high voltage negative high voltage obtained after negative voltage multiplication is used as negative high voltage pole.The positive pole of the direct current high voltage is used as the opposite electrode with the negative high voltage pole, and a negative high voltage difference is formed between the two.

[0003] In actual design and application of air purifier product, the negative high voltage electrode and opposite electrode of negative ion generator are exposed to air and form a pressure difference ionization air with a certain distance.The negative high voltage pole is connected to the release tip made of conductive material such as metal or carbon element, and high corona ionization air is generated by the direct current high voltage of the tip, and a large number of electrons (e-) are emitted into the air at high speed, and the electrons combine with oxygen and other substances in the air to form air negative ions.The opposite electrode is connected to the conductive end made of conductive material such as metal or carbon element, and forms a pressure difference ionization air with the negative high voltage electrode, and forms a loop in the circuit of the negative ion generator device after recovering electrons (e-) from the air.The more electrons recovered from the air by the opposite electrode, the greater the internal loop current, the more electrons emitted into the air by the negative high voltage electrode, and the higher the concentration of air negative ions formed.

[0031] Example 1

[0032] Reference Figures 1 to 5 , a kind of arrangement structure for improving the negative ion concentration of negative ion air purifier, it includes negative ion generator 9 and electronic transmission medium 3, the negative ion generator 9 is equipped with negative high voltage electrode 1, and opposite electrode 2 arranged with negative high voltage electrode 1 spacing, the end of negative high voltage electrode 1 has negative high voltage electrode conductive tip 10.The end of opposite electrode 2 has opposite electrode conductive end 20, and opposite electrode conductive end 20 is made of metal or carbon fiber material.The electronic transmission medium 3 is arranged in the vicinity of opposite electrode conductive end 20, and the electronic transmission medium 3 has electronic transmission interface 30 arranged in the vicinity of opposite electrode conductive end 20.

[0033] In the embodiment, as shown in Figures 1 to 3 Specifically, the negative ion generator 9 is specifically applied to a kind of negative ion air purifier.The negative ion air purifier specifically includes shell 6, the shell 6 has air outlet 60, and the negative ion generator 9 is arranged in the shell 6.The negative high voltage electrode 1 is located in the vicinity of air outlet 60, and the negative high voltage electrode conductive tip 10 of the negative high voltage electrode 1 is arranged opposite air outlet 60.The bottom plate on the bottom of shell 6 has bottom opening 61, and the opposite electrode 2 is located in the vicinity of bottom opening 61, and the opposite electrode conductive end 20 of the opposite electrode 2 has the arrangement opposite bottom opening 61.

[0034] As shown in Figure 1 and Figure 3 , the electron-conducting medium 3 is a supporting table component for placing the negative ion air purifier, specifically a table for placing the negative ion air purifier. The electron-conducting interface 30 is the supporting table surface of the supporting table component, that is, the table surface of the table.

[0035] Further, the vertical distance H between the relative electrode conducting end 20 and the electron-conducting interface 30 in this embodiment is 0-5 mm. The following detailed description is made for the range of 0-5 mm for H.

[0036] First, as shown in Figure 4 , the relative electrode conducting end 20 can contact the electron-conducting interface 30, that is, the vertical distance H between the relative electrode conducting end 20 and the electron-conducting interface 30 is specifically 0 mm. At this time, the relative electrode 2 obtains electrons from the air during the air ionization process, and at the same time, the conducting end 20 contacts the supported table surface, that is, the electron-conducting interface 30, and obtains a large number of electrons by using the large-area contact between the electron-conducting interface 30 and the air. The increase in the number of obtained electrons increases the internal loop current, and the number of electrons emitted by the negative high-voltage electrode 1 into the air is greater, and the concentration of air negative ions formed is higher.

[0037] Second, as shown in Figure 5 , the relative electrode conducting end 20 can also not contact the electron-conducting interface 30, so that the vertical distance H between the relative electrode conducting end 20 and the electron-conducting interface 30 is not more than 5 mm. At this time, the distance between the relative electrode conducting end 20 and the electron-conducting interface 30 is short, and the high-voltage ionization breakdown of the air occurs, and the relative electrode 2 obtains electrons from the air during the air ionization process, and at the same time, the conducting end 20 obtains a large number of electrons from the electron-conducting interface 30 by ionizing and breaking down the air of the electron-conducting interface 30. The increase in the number of obtained electrons increases the internal loop current, and the number of electrons emitted by the negative high-voltage electrode 1 into the air is greater, and the concentration of air negative ions formed is higher.

[0038] Embodiment 2

[0039] With reference to Figure 6 and Figure 7 , the arrangement structure for increasing the concentration of negative ions of the negative ion air purifier in this embodiment is different from that in Embodiment 1 in that in this embodiment, a conducting sheet 4 is further arranged between the relative electrode conducting end 20 and the electron-conducting interface 30. The conducting sheet 4 is made of a conductive material, specifically made of conductive rubber. One side of the conducting sheet 4 contacts the electron-conducting interface 30. The conducting sheet 4 is arranged below or directly below the relative electrode conducting end 20.

[0040] The conductive sheet 4 is arranged on the side of the opposite electrode conductive end 20. The conductive sheet opening 40 is arranged on the conductive sheet 4, opposite the opposite electrode conductive end 20. The conductive sheet opening 40 is in the shape of an open horseshoe (as shown in Figure 8 Fig. 2), but can also be in the shape of a closed ring.

[0041] Further, the vertical distance h between the opposite electrode conductive end 20 and the conductive sheet 4 is 0-2 mm. The range of 0-2 mm is described in detail below.

[0042] First, when the bottom surface of the opposite electrode conductive end 20 is level with the top surface of the conductive sheet 4 (not shown in the figure), that is, the vertical distance h between the opposite electrode conductive end 20 and the conductive sheet 4 is 0 mm. At this time, the surface area of the conductive sheet 4 is larger than the surface area of the conductive end 20 of the opposite electrode 2, and directly contacts the support table surface (that is, the electron conducting interface 30). The good conductivity of the conductive sheet 4 allows the electrons to be quickly conducted to the vicinity of the opposite electrode conductive end 20 along the electron conducting interface 30 and the conductive sheet 4.

[0043] Second, as shown in Figure 7 Fig. 3, the vertical distance h between the opposite electrode conductive end 20 and the conductive sheet 4 is not more than 2 mm. At this time, the distance between the opposite electrode conductive end 20 and the conductive rubber (that is, the conductive sheet 4) is short, and the phenomenon of high-voltage ionization breakdown of air is prone to occur, so that a large number of electrons are obtained from the support table surface through the conductive rubber. The increase in the number of obtained electrons increases the internal loop current, and the number of electrons emitted by the negative high-voltage electrode 1 into the air increases, and the concentration of air negative ions formed is higher.

[0044] Embodiment 3

[0045] Specifically referring to Figures 9 to 11 , the arrangement structure for increasing the concentration of negative ions of the air purifier of the present embodiment is different from that of Embodiment 1 in that the present embodiment further comprises a conductive swing arm 52 arranged near the opposite electrode conductive end 20. The conductive swing arm 52 is made of conductive material, and is specifically made of conductive rubber. One side surface of the conductive swing arm 52 contacts the electron conducting interface 30 and is rotatably arranged by a motor 5. The output shaft of the motor 5 is coaxially connected with a shaft portion 50, and the distal end of the shaft portion 50 is perpendicularly connected with the conductive swing arm 52, so that the conductive swing arm 52 can be rotated to contact the opposite electrode conductive end 20 or can be rotated to not contact the opposite electrode conductive end 20.

[0046] In the above structure, the conductive swing arm 52 of the conductive material is in long-term contact with the supporting table top (i.e. the electron-conducting interface 30). During the rotation of the shaft part 50, the conductive swing arm 52 is in contact with the conductive end 20 of the opposite electrode 2, i.e. the conductive end 20 of the opposite electrode can be connected to the supporting table top through the conductive swing arm 52, thereby obtaining a large number of electrons. The increase of the obtained electrons increases the internal loop current, and the more the number of electrons emitted by the negative high-voltage electrode 1 into the air, the higher the concentration of air negative ions formed. During the swing of the shaft part 50, the conductive swing arm 52 can also be separated from the conductive end 20 of the opposite electrode 2, i.e. the conductive end 20 of the opposite electrode is separated from the supporting table top, thereby realizing the adjustability of the negative ion concentration of the air purifier. The main material of the shaft part 50 is a high-insulation material such as engineering plastic, which can effectively avoid the conduction of the charge on the opposite electrode 2 to the stepping motor 5 through the shaft part 50, and ensure the stable work of the electric control system.

[0047] Further, as shown in Figure 11 , in order to ensure the use effect of the conductive swing arm 52 which is too soft, avoid the conductive swing arm 52 being too soft, and facilitate the replacement of the conductive swing arm 52 after being damaged, the end of the shaft part 50 also has a horizontal arm part 51, and the conductive swing arm 52 is connected to the horizontal arm part 51.

[0048] Further, the conductive swing arm 52 has a protrusion 53 on one side surface thereof, and contacts the electron-conducting interface 30 through the protrusion 53. In the above structure, the contact between the side surface of the conductive swing arm 52 and the electron-conducting interface 30 is realized through the protrusion 53, which also plays a role in reducing the rotating friction of the conductive swing arm 52, and ensures the effective operation of the conductive swing arm 52.
