Abstract
Description
Technical Field
[0001] This invention belongs to the field of ozone equipment and relates to an ozone generator. Background Technology
[0002] In existing ozone generators, the discharge unit typically includes a pair of discharge unit mounting plates, several concentrically mounted external electrodes, dielectric tubes, and internal electrodes. The mounting plates, external electrodes, and internal electrodes are generally made of metal, and the external electrodes are fixed and sealed to the mounting plate by welding.
[0003] Because the weld joint may not be smooth, and may contain protrusions or burrs, vibrations caused by the discharge during ozone generator operation can cause the dielectric tube to collide with the weld joint, potentially damaging the dielectric tube and leading to leaks. This could then damage the discharge unit or even the entire ozone generator. Furthermore, the external electrode opening may also be rough; vibrations caused by the discharge during ozone generator operation can cause the dielectric tube to collide with the external electrode opening, also damaging the dielectric tube and leading to leaks. This could further damage the discharge unit or even the entire ozone generator.
[0004] Therefore, a simple and durable ozone generator is needed to meet practical needs. Summary of the Invention
[0005] The purpose of this invention is to provide an ozone generator that can overcome the above-mentioned shortcomings.
[0006] The ozone generator of the present invention is implemented as follows: an ozone generator includes a first gas chamber, a second gas chamber, a cooling chamber, a pair of discharge unit fixing plates, and a plurality of discharge units. The discharge unit fixing plates are respectively fixed between the two gas chambers and the cooling chamber. Each discharge unit includes an inner electrode, a dielectric tube, and an outer electrode. The inner electrode is located inside the dielectric tube, and the outer electrode is sleeved outside the dielectric tube. The discharge unit has a discharge gas gap. The characteristic feature is that: the two ends of the outer electrode pass through the discharge unit fixing plates, and at least one end of the outer electrode passes through the discharge unit fixing plate and extends into the corresponding gas chamber. There is a distance between the end of the outer electrode extending into the gas chamber and the discharge unit fixing plate it is located on.
[0007] To achieve better technical results, the ozone generator of the present invention may also have the following specific technical features:
[0008] 1. The first end of the external electrode extends into the first air chamber by a certain distance. The first end of the external electrode is in the shape of a flared mouth. The wide opening of the flared mouth is located in the first air chamber, and the inner side of the narrow opening of the flared mouth is rounded and smooth.
[0009] 2 The second end of the external electrode extends into the second air chamber by a certain distance. The first end and the second end of the external electrode are in the shape of a flared mouth. The wide opening of the flared mouth is located in the corresponding air chamber, and the inner side of the narrow opening of the flared mouth is rounded and smooth.
[0010] 3 The inner electrode is a high-voltage electrode, and the first end of the inner electrode is connected to the positive terminal of the power supply.
[0011] 4. The inner electrode is a high-voltage electrode, and one or both ends of the inner electrode are simultaneously connected to the positive terminal of the power supply.
[0012] 5. The distance between the end of the external electrode extending into the gas chamber and the fixing plate of the discharge unit where it is located shall not exceed 10 mm.
[0013] 6. The distance between the end of the external electrode and the fixing plate of the discharge unit is between 2 and 8 mm.
[0014] 7 The inner electrode, dielectric tube and outer electrode are concentric circle structures. There is a discharge gap between the inner electrode and the dielectric tube or between the dielectric tube and the outer electrode, or there are discharge gaps between the inner electrode and the dielectric tube and between the dielectric tube and the outer electrode at the same time.
[0015] 8 The inner electrode, dielectric tube and outer electrode are non-concentric circle structures. There is a discharge gap between the inner electrode and the dielectric tube or between the dielectric tube and the outer electrode, or there are discharge gaps between the inner electrode and the dielectric tube and between the dielectric tube and the outer electrode at the same time.
[0016] The external electrode described in 9 is welded and sealed to the discharge unit fixing plate.
[0017] The ozone generator using the technical solution of this invention has the following advantages:
[0018] 1. The welding point between the external electrode and the fixed plate is a certain distance away from the end of the external electrode to avoid the discharge between the internal electrode and the external ground electrode damaging the weld and causing leakage due to poor sealing between the external electrode and the fixed plate; effectively reducing the equipment failure rate, extending the service life of the equipment, and saving maintenance costs.
[0019] 2. The welding point between the external electrode and the fixed plate is a certain distance away from the end of the external electrode to avoid damage to the dielectric tube caused by an uneven welding point, which could lead to the breakage of the dielectric tube and consequently damage to the discharge unit or even the ozone generator; thus reducing the equipment failure rate and saving maintenance costs.
[0020] 3. The end of the external electrode is flared, and the inner side of the narrow opening of the flared opening is rounded and smooth. When the ozone generator vibrates during discharge, it protects the dielectric tube from being damaged by the external electrode port, extends the life of the dielectric tube, reduces the equipment failure rate, and saves maintenance costs.

The discharge unit fixing plates 104 are sealed with the corresponding gas chamber and cooling chamber. The discharge unit 200 includes an inner electrode 1, a dielectric tube 2, and an outer electrode 3. The inner electrode 1 is located inside the dielectric tube 2, and the outer electrode 3 is sleeved outside the dielectric tube 2. The discharge unit 200 has a discharge gap 4. The first end 31 and the second end 32 of the external electrode are mounted on the discharge unit fixing plate 104. The first end 31 and the second end 32 of the external electrode respectively pass through their respective discharge unit fixing plates 104 and extend into the corresponding first gas chamber 101 or second gas chamber 102. The external electrode 3 is welded and sealed to the discharge unit fixing plate 104.

Preferably, the distance between the second end of the external electrode and its respective discharge unit fixing plate does not exceed 10 mm.
[0028] In this embodiment, the inner electrode 1 is a high-voltage electrode. The first end 11 of the inner electrode 1 is connected to the positive terminal of the power supply.

[0030] Preferably, the distance between the outer edge of the wide opening of the horn 5 and the fixing plate of the discharge unit is between 2 and 8 mm.
[0031] In practical applications, one end of the external electrode can extend a certain distance into the corresponding first or second air chamber. The extended end of the external electrode is shaped like a flared mouth, with the wide opening of the flared mouth located within the corresponding air chamber, and the inner side of the narrow opening of the flared mouth being rounded and smooth.
[0032] In this embodiment, the first end 11 of the inner electrode is connected to the positive terminal of the power supply. In practical applications, the second end 12 of the inner electrode can also be connected to the positive terminal of the power supply, or both ends of the inner electrode can be connected to the positive terminal of the power supply at the same time.
[0033] Preferably, in this embodiment, the inner electrode 1, the dielectric tube 2, and the outer electrode 3 are concentric circles, and a discharge gap 4 exists between the dielectric tube and the outer electrode. In practical applications, a discharge gap may also exist between the inner electrode 1 and the dielectric tube 2, or a discharge gap 4 may exist simultaneously between the inner electrode and the dielectric tube, and between the dielectric tube and the outer electrode.
[0034] In practical applications, the inner electrode, dielectric tube, and outer electrode can also be non-concentric circular structures. There is an air gap between the inner electrode and the dielectric tube, or a discharge air gap 4 between the dielectric tube and the outer electrode, or a discharge air gap 4 exists simultaneously between the inner electrode and the dielectric tube, and between the dielectric tube and the outer electrode.
