Description

Technical Field

[0001] The utility model relates to the field of plasma air purifiers, in particular to a double-base straight-through tube type plasma air generator. Background Art

[0002] The main working principle of the plasma generator is to increase the low voltage to positive high voltage and negative high voltage through a boost circuit, and use the positive high voltage and negative high voltage to ionize the air (mainly oxygen) to produce a large number of positive ions and negative ions. The number of negative ions is greater than the number of positive ions (the number of negative ions is approximately 1.5 times the number of positive ions).

[0003] As the requirements for air purifiers increase, plasma air purifiers have the advantages of good air purification effect and non-irritation (compared with ultraviolet irradiators and ozone generators).

[0004] Existing plasma air purifiers, such as Chinese patent CN201620871606.7, use a single base installation method, which has the following disadvantages:

[0005] (1) The installation stability of the single base is difficult to fasten with the straight glass tube and the assembly is cumbersome. In addition, a large amount of glue and adhesive (to achieve relative sealing) and other environmental pollutants are required for bonding between the single base and the straight glass tube, which will pollute the environment;

[0006] (2) The inner electrode assembly is difficult to tighten, which affects the stable release of plasma and is cumbersome to assemble;

[0007] (3) The outer electrode metal mesh has an outward tension, which causes insufficient elastic contact between it and the outer side of the glass tube and makes it easy to loosen and slide off the end of the glass cover, affecting the stable release of plasma;

[0008] (4) The outer electrode of the plasma tube cannot be well connected to the wire, which affects the stable release of plasma and makes the assembly complicated;

[0009] (5) The manufacturing and assembly process has high requirements;

[0010] (6) The stability of the plasma air generator is greatly affected by the above factors. Utility Model Content

[0011] The main purpose of the utility model is to propose a double-base straight-through tube plasma air generator, which aims to facilitate the assembly of inner electrode components and outer electrode components through the structure of double insulating bases, and the straight-through glass tube has good sealing performance and does not need to be sealed with glue or other materials.

[0012] To achieve the above object, the utility model proposes a double-base straight-through tube plasma air generator, comprising:

[0013] A straight glass tube, wherein the straight glass tube is a tube body with a chamber inside, and a first insulating base and a second insulating base are respectively provided on both sides of the straight glass tube;

[0014] An inner electrode assembly, the inner electrode assembly comprising an inner conductive screw and an inner electrode metal mesh sleeved on the outer peripheral wall of the inner conductive screw, one end of the inner conductive screw extending out of the first insulating base and connected to the first nut assembly, the other end of the inner conductive screw being connected via a single-head screw assembly mounted on the second insulating base, the inner electrode metal mesh being arranged in the chamber, and both ends of the inner electrode metal mesh being against the inner wall of the first insulating base and the inner wall of the second insulating base;

[0015] The outer electrode assembly comprises an outer electrode metal mesh, the inner peripheral wall of the outer peripheral wall of the outer peripheral wall of the straight glass tube is in contact with the outer peripheral wall of the straight glass tube.

[0016] In the actual design, the straight glass tube is relatively fixed and sealed by setting a double insulating base and cooperating with an inner conductive screw. The structure is simple and the assembly is convenient.

[0017] In actual work, plasma is generated by the cooperation of the inner electrode metal mesh and the outer electrode metal mesh. Specifically, when the power is on, an induced electric field is generated between the inner electrode metal mesh and the outer electrode metal mesh to make the gas conductive and generate plasma air. The plasma air has the ability to actively sterilize, disinfect and remove odor, purify the air and decompose toxic and harmful gases in the air.

[0018] 1. When using a double-base straight-through tube plasma air generator and installing it on the matching air purifier, you can choose a single-head fixed plasma air generator or a double-head fixed plasma air generator according to the internal structure of the air purifier itself, giving you more and better choices when designing the air purifier;

[0019] 2. When using a double-base straight-through tube plasma air generator and installing it at the air purifier or fresh air duct outlet, fix the two ends of the plasma air generator horizontally on the inside of the outlet, which can not only ensure stability, but also make the released plasma air fully diffuse out of the outlet;

[0020] 3. Use a double-base straight-through tube plasma air generator, with the inner and outer electrodes fixed on different insulating base ends, which can better ensure the insulation distance between the inner and outer electrodes. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] An inner electrode assembly 2, the inner electrode assembly 2 comprising an inner conductive screw 21 and an inner electrode metal mesh 22 sleeved on the outer peripheral wall of the inner conductive screw 21, one end of the inner conductive screw 21 extends out of the first insulating base 11 and is connected to the first nut assembly 4, the other end of the inner conductive screw 21 is connected through a single-head screw assembly 6 installed on the second insulating base 12, the inner electrode metal mesh 22 is arranged in the chamber, and the two ends of the inner electrode metal mesh 22 are against the inner wall of the first insulating base 11 and the inner wall of the second insulating base 12;

[0038] The outer electrode assembly 3 includes an outer electrode metal mesh 31 , and the inner peripheral wall of the outer peripheral wall of the outer electrode metal mesh 31 is in contact with the outer peripheral wall of the straight glass tube 1 .

[0039] In the actual design, the straight glass tube 1 is relatively fixed and sealed by setting the double insulating base and cooperating with the inner conductive screw 21, and the structure is simple and the assembly is convenient.

[0040] In actual work, plasma is generated by the cooperation of the inner electrode metal mesh 22 and the outer electrode metal mesh 31. Specifically, when the power is on, an induced electric field is generated between the inner electrode metal mesh 22 and the outer electrode metal mesh 31 to make the gas conductive and generate plasma air. The plasma air has the ability to actively sterilize, disinfect and remove odor, purify the air and decompose toxic and harmful gases in the air.

[0041] 1. When using a double-base straight-through tube plasma air generator and installing it on the matching air purifier, you can choose a single-head fixed plasma air generator or a double-head fixed plasma air generator according to the internal structure of the air purifier itself, giving you more and better choices when designing the air purifier;

[0042] 2. When using a double-base straight-through tube plasma air generator and installing it at the air purifier or fresh air duct outlet, fix the two ends of the plasma air generator horizontally on the inside of the outlet, which can not only ensure stability, but also make the released plasma air fully diffuse out of the outlet;

[0043] 3. Use a double-base straight-through tube plasma air generator, with the inner and outer electrodes fixed on different insulating base ends, which can better ensure the insulation distance between the inner and outer electrodes.

[0044] Specifically, the diameter of the first insulating base 11 and the diameter of the second insulating base 12 are larger than the diameter of the straight glass tube 1 and the diameter of the outer electrode metal mesh 31 , thereby achieving positioning and limiting of the outer electrode metal mesh 31 and the straight glass tube 1 .

[0048] Specifically, the inner conductive screw 21 is provided with an outer thread, and the inner electrode metal mesh is wound along the outer thread and has a spiral structure. This structure can ensure that the outer peripheral wall of the inner electrode metal mesh and the inner peripheral wall of the straight glass tube are elastically offset, and have a large friction resistance. After the inner electrode metal mesh 22 is assembled to the straight glass tube, the inner electrode metal mesh 22 is not easy to produce relative displacement, thereby ensuring the stable conduction of the inner electrode metal mesh.

[0049] In the embodiment of the utility model, the second insulating base 12 is provided with a second through hole 121, and the single-threaded screw assembly includes a single-threaded single-threaded insulating screw and an outer electrode wire fixing nut, the single-threaded single-threaded insulating screw is provided with an inner thread, and the inner conductive screw extends out of the second through hole and is screwed into the inner thread. Therefore, the plasma air generator can be assembled by cooperating with the single-threaded single-threaded insulating screw 61 and the inner electrode fixing nut 41 of the inner conductive screw 21, and the disassembly and maintenance are relatively convenient.

[0050] Specifically, a negative power wire 52 is provided between the single-pass single-head insulating screw 61 and the outer electrode wire fixing nut 62 , and a special-shaped conductive spring 7 is extended from the negative power wire toward the outer electrode metal mesh 31 , thereby ensuring that the outer electrode metal mesh 31 is energized.

[0051] In the embodiment of the utility model, the outer electrode metal mesh 31 is a circular mesh structure arranged vertically and horizontally, thereby ensuring the magnetic induction contact area between the inner electrode metal mesh 22 and the outer electrode metal mesh 31 .

[0052] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
