Description

Technical Field

[0001] This utility model relates to the field of cold plasma structure technology, specifically a detachable cold plasma structure. Background Technology

[0002] Cold plasma (low-temperature plasma) is a non-thermal equilibrium plasma. Its core characteristic is that the electron temperature is much higher than the temperature of ions and neutral particles, and the overall temperature is close to room temperature. This unique energy distribution endows cold plasma with specific structure and physical properties, making it widely applicable in materials processing, biomedicine, environmental remediation and other fields. A cold plasma structure is a cold plasma generator that uses dielectric barrier discharge for ionization. In the existing technology, the copper foil electrodes on the outside of the cold plasma structure need to be installed at equal intervals. The manual installation process is prone to deviations, making the installation accuracy less than ideal.

[0003] For example, patent publication number CN216440598U describes a multi-electrode dielectric barrier discharge low-temperature plasma reactor. It includes an outer insulating dielectric cylinder with a fluid inlet and a fluid outlet, a closed inner insulating dielectric cylinder housed within the outer cylinder, and a plasma light source installed inside the inner cylinder. Multiple parallel-connected external electrodes are spaced at intervals on the outer wall of the outer insulating dielectric cylinder, while a central electrode is located inside the inner cylinder. This reactor uses multiple parallel external electrodes, increasing the number of electrode edges and enhancing the edge effect. This is beneficial for increasing the proportion of corona discharge in the plasma discharge mode, reducing the current generated during discharge, improving the surface treatment effect and quality of samples, and enabling the reactor to operate safely and stably for extended periods. This facilitates the widespread application of plasma reactors in various industries. However, a problem exists: the copper foil electrodes on the outside of this cold plasma structure need to be installed at equal intervals, which can easily lead to deviations during manual installation, resulting in less than ideal installation accuracy.

[0008] Preferably, the guide slider matches the guide groove, and the plurality of mounting seats are slidably connected to the guide slider through the guide groove, so as to provide a good guiding effect for the movement of the mounting seats.

[0009] Preferably, one end of the fixing sleeve has a through groove, and the positioning sleeve passes through the through groove and extends to the outside of the fixing sleeve, so that the positioning sleeve can be easily moved from the outside, thereby adjusting the distance between the copper foil electrodes.

[0010] Preferably, the positioning rod is fixedly installed on the outer surface of the fixed sleeve, and the through hole matches the positioning rod, so that the positioning sleeve can move along the positioning rod using the through hole.

[0011] Preferably, the locking bolt has an internal hexagonal groove at its end, and the pin matches the insertion hole, so that the pin can be inserted into the insertion hole for locking.

[0012] Preferably, the installation mechanism includes an installation base, a threaded block is fixedly connected to the top of the installation base, an installation screw hole is opened at the bottom end of the inner electrode cylinder, a sealing groove is opened on the top surface of the installation base, and a sealing ring is installed inside the sealing groove, which can facilitate the installation and removal of the inner electrode cylinder and increase the sealing performance.

[0013] This invention provides a detachable cold plasma structure. Compared with the prior art, it has the following advantages:

[0014] 1. This detachable cold plasma structure involves attaching copper foil electrodes to the inside of the mounting base, then using bolts to fix the fixing sleeves to the outer cylinder.

[0023] The detachable external electrode mechanism 2 includes a fixing sleeve 201 with multiple fixing holes 202. The outer cylinder 1 has connecting screw holes that match the fixing holes 202. The fixing sleeve 201 is detachably connected to the outer cylinder 1 via bolts, connecting screw holes, and fixing holes 202, allowing for easy fixation of the fixing sleeve 201 to the outer cylinder 1. Two guide sliders 203 are fixedly connected to the inner wall of the fixing sleeve 201. Multiple mounting seats 204 are provided between the two guide sliders 203, and each mounting seat 204 has a guide hole on its outer surface. The guide slider 203 matches the guide groove 205. Multiple mounting seats 204 are slidably connected to the guide slider 203 via the guide groove 205, which provides good guidance for the movement of the mounting seats 204. A copper foil electrode 206 is bonded to the inner side of the mounting seat 204. The end of the copper foil electrode 206 is connected to an external wiring 208 via a connecting terminal 207, which allows for easy connection and disconnection of the copper foil electrode 206 and the external wiring 208. Positioning sleeves 209 are fixedly connected to the outer surfaces of multiple mounting seats 204. One end of the fixed sleeve 201 has a through groove, and the positioning sleeve 209 passes through the through groove and extends to the outside of the fixed sleeve 201, allowing the positioning sleeve 209 to be easily moved from the outside, thereby adjusting the distance between the copper foil electrodes 206. The positioning sleeve 209 has a through hole 210, inside which is a positioning rod 211. The positioning rod 211 is fixedly installed on the outer surface of the fixed sleeve 201. The through hole 210 matches the positioning rod 211, allowing the positioning sleeve 209 to move along the positioning rod 211 using the through hole 210. The positioning rod 211... The device is equipped with a scale strip 212 and multiple insertion holes 213. The scale strip 212 allows installers to more intuitively determine the distance between the copper foil electrodes 206, improving installation accuracy. The end of the positioning sleeve 209 is threaded with a locking bolt 214, and the end of the locking bolt 214 is fixedly connected with a pin 215. The end of the locking bolt 214 has an internal hexagonal groove, which allows the locking bolt 214 to be easily rotated with a tool. The pin 215 matches the insertion hole 213, allowing the pin 215 to be inserted into the insertion hole 213 for locking.

[0024] Please see Figure 4The installation mechanism 4 includes an installation base 401, which is fixed to the bottom of the inner side of the outer cylinder 1. A threaded block 402 is fixedly connected to the top of the installation base 401. An installation screw hole is opened at the bottom of the inner electrode cylinder 3. A sealing groove 403 is opened on the top surface of the installation base 401. A sealing ring 404 is installed inside the sealing groove 403. By inserting the sealing ring 404 into the sealing groove 403 and then screwing the installation screw hole into the threaded block 402, the inner electrode cylinder 3 can be easily installed and removed, and the inner electrode cylinder 3 can press the sealing ring 404, thereby increasing the sealing between the inner electrode cylinder 3 and the installation base 401.

[0025] During operation, the copper foil electrode 206 is adhered to the inside of the mounting base 204, and then the fixing sleeve 201 is fixed to the outer cylinder 1 using bolts. The positioning sleeve 209 is moved, which moves the mounting base 204, which in turn moves the copper foil electrode 206. The positioning sleeve 209 moves along the surface of the positioning rod 211. The installer can observe the scale on the edge of the positioning sleeve 209 to determine the distance between two adjacent positioning sleeves 209. Multiple positioning sleeves 209 are moved to the designated scale positions in sequence, and then the locking bolt 214 is rotated. The locking bolt 214 inserts the pin 215 into the insertion hole 213 for locking, so that the distance between multiple copper foil electrodes 206 is equal, which effectively improves the installation accuracy and allows for disassembly and replacement.
