V. New description: [New technical field] The present invention relates to a plasma device, and in particular to an atmospheric plasma device. [Prior Art] With the development of plasma technology, atmospheric arc plasma in plasma has been widely used in surface treatment in various fields. For example, atmospheric electricity can be surface treated with an arc plasma to improve the reliability of processes such as adhesion, printing, packaging, or sizing on the surface of the object. However, limited by the negative resistance of the arc, such arc-type atmospheric plasma has a limited processing range and cannot simultaneously generate a large area of arc discharge. Although the discharge density of the arc-type atmospheric plasma is high, the plasma technology produces more active substances, which can greatly increase the speed of the plasma processing, and the surface of the scanning area can be completed by only a short scan. deal with. However, the inability to produce large-area arc discharges will still result in limited application of such electro-arc atmospheric plasma. In order to improve the applicability of arc-type atmospheric plasma, U.S. Patent No. 6,262,386 proposes a plasma device in which an arc-type plasma nozzle is rotatable. In this plasma device design, the nozzle is inclined at an angle with respect to the axis of the inner electrode, and the nozzle and the outer electrode are circumferentially rotated about the axis. With such a design, when the plasma is ejected, the rotation of the nozzle can increase the plasma ejection area. At this time, the effect of large-area processing can be achieved by moving the object to be processed. However, by rotating the nozzle to expand the effective area of the plasma treatment, it is necessary to provide more power to the plasma device to produce the desired plasma. However, the application of high power causes the rod-shaped inner electrode to be damaged by the concentration of the plasma at a single point. [New content] Therefore, one aspect of the present invention is to provide a plasma device in which the inner electrode and the outer electrode have a tubular structure, thereby avoiding the concentration of the arc at a single point, and avoiding damage to the electrode, thereby effectively extending the electrode.

In this way, the plasma injection area of the plasma device can be enlarged, so that the plasma device can provide a large-area treatment effect, which helps to shorten the time for the electricity to be processed. Another aspect of the present invention is to provide a plasma device having a gas passage between the tubular inner electrode and the insulating lining of the outer casing, so that the flow of the working gas in the gas passage can be utilized to cool the tubular inner electrode. Effective φ reduces the operating temperature of the tubular inner electrode, which in turn can effectively extend the service life of the tubular inner electrode. According to the above object of the present invention, a plasma device is proposed. The plasma apparatus includes a housing, a tubular inner electrode, a first swirl generator, a tubular outer electrode, and a nozzle. The outer casing has a first chamber and the side of the first chamber is covered with an insulating lining. The tubular inner electrode is disposed in the first chamber and has a second chamber. The first swirl generator is coupled to the aforementioned tubular inner electrode. Wherein the first swirling flow generator comprises at least one first air inlet, and the at least one first air inlet is adapted to use the working air in the first chamber 5 M426456.

The nozzle 132 is fixed to the bottom of the tubular outer electrode in a non-bearing manner, i.e., the spray 32 does not correspond to the tubular outer electrode 128. The nozzle 132 can pass through the tubular outer electrode 128 and the support 126 to which it is coupled, and Rotating in the outer casing 102. The mouth 132 is disposed obliquely below the tubular outer electrode (3) so that the nozzle has an angle - between the axis 136 of the tubular: 128. In some examples, 0 is greater than 0 degrees and less than 90 degrees. The material of the bearing 126 may be gold. The potential of the tubular outer electrode 128 and the nozzle is permeable: to the outer casing 102. 6 and M426456 In one embodiment, the tubular inner electrode 110, the tubular outer electrode 128 and the nozzle 132 are concentric. That is, the axis of the opening 156 where the nozzle 132 is engaged with the chamber 130 of the tubular outer electrode 128 is the same as the axis of the tubular inner electrode 110 and the tubular outer electrode 128. In another embodiment, the tubular inner electrode 110, the tubular outer electrode 128, and the nozzle 132 are off-axis. For example, the tubular inner electrode 110 is different from the axis of the tubular outer electrode 128, but may be the same as the axis of the opening 156 of the nozzle 132; or the axis of the opening 156 of the nozzle 132 and the tubular outer electrode 128 and the tubular inner electrode 110 The axis of the tube is different; or the tubular inner electrode 110, the tubular outer electrode 128, and the axis of the opening 156 of the nozzle 132 are different. In one embodiment, as shown in Figure 1, the plasma device 100 can further include a non-DC power source, such as an AC power source 138. The AC power source 138 is electrically connected to the tubular inner electrode 110 and the outer casing 102. Thus, an alternating current source 138 can be used to apply electrical current to the tubular inner electrode 110 and the outer casing 102. Wherein the tubular inner electrode 110 is a high voltage end and the outer casing 102 is opposite to the low voltage end or the ground end. When the plasma device 100 is operated, the desired working gas 158 is first supplied and the working gas 158 is passed into the chamber 104 of the outer casing 102. The working gas 158 will flow down the gas passages 148 between the tubular inner electrode 110 and the insulating lining 108 to the swirling flow generators 114 and 120. The working gas 158 then swirls into the chamber 112 of the tubular inner electrode 110 from the inlet 116 of the swirl generator 114 and the inlet 122 of the swirl generator 120. After the working gas 158 enters the chamber 112 in a swirling manner from the swirling generator 120, it will follow the inner side of the upper tubular inner electrode 110 and the inner side of the bottom portion 124 of the outer casing 102 and the tubular outer electrode 128, respectively. The inner side of the side flows upwards and downwards. The working gas entering the chambers 112, 叱 and 130 <RTI ID=0.0>> An electric arc (10) is generated, "60, which can be rotated: two 8 =: two to make the working gas 158 generate an activation reaction, the emulsion is 14 〇 ionized" and in the mode, the arc 160 and the electric polymerization are equal to the tube = the plasma. The arc of the working gas 158 is 11 〇 and the tubular outer electrode 110 and the tubular outer electrode 128 " a rotating air flow will push the arc of the tube arc around the tubular inner electrode 11 () The root causes the chamber 130 to make a circular motion. The tubular outer electrode 128 132' is converted from the working gas into "two: the electrode 128 is guided out of the nozzle, and the object to be processed is electrically y processed 4". The self-plasma device 100 is known from the above embodiments, the new electrode; the inner electrode and the outer electrode are both tubular knots, m has the advantage that the plasma device is single-point, and the teeth avoid damage to the electrodes, and the arc can be avoided. From the above embodiments, the electrode life is known. The electrode has an outer electrode that can be rotated around the outer casing, because the advantage is that the plasma package is expanded into a line shape, thereby expanding the electric material to be sprayed from a dot shape to a green shape, and the plasma spray electropolymer device for the large area is provided for a large area. The processing effect helps _ electricity time. It can be seen from the above embodiments that the insulating inner lining of the tubular inner electrode and the outer casing which is too reported is== this can be used to cool the tubular internal electricity of the m-channel; and the second can be used for the temperature, which can be effectively extended. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this new type is subject to the definition of the scope of the patent application.
