Description

Technical Field

[0001] This utility model relates to the field of ozone generator manufacturing technology, and more specifically to a planar generator. Background Technology

[0002] An ozone generator is a device used to produce ozone gas (O3). Ozone is easily decomposed and cannot be stored; it must be produced and used on-site (short-term storage is possible under special circumstances). Therefore, an ozone generator is required wherever ozone can be used.

[0003] According to invention patent application CN111847391A, published on October 30, 2020, a portable ozone generator is disclosed, comprising: a housing and a discharge assembly disposed within the housing. The discharge assembly includes: a support, a main control board with high-voltage devices, and electrode plates disposed on the support. A vent cover is placed on the top of the housing, and the electrode plates are placed inside the vent cover. The space enclosed by the electrode plates and the opposite vent cover is a corona space. During operation, the vent cover is connected to the main control board as a cathode, and the electrode plates are connected to the main control board as an anode. The air in the corona space is ionized to generate ozone, which is released through the vent cover. The electrode plates have upright discharge bodies arranged on their four sides. The cross-sectional width of the discharge bodies gradually decreases from the bottom to the top, eventually forming a sharp angle at the top. Its main technical advantages are: the ozone generator is small in size, easy to carry, and has a simple internal structure, making it convenient to use.

[0004] Most existing ozone generators are modular in design, using individual ozone generating modules installed inside the casing to generate ozone. Due to the modular design, the ozone generating modules are relatively large, resulting in a bulky final product that is inconvenient to carry. To address this issue, a planar generator is proposed to solve the problem of bulky and inconvenient final product caused by the modular design of ozone generating modules in existing technologies.

One end of the connecting piece is connected to the inner electrode, and the other end is bent and connected to the other side of the insulating dielectric plate. The insulating dielectric plate is disposed within the generating cavity, and an insulating layer is filled into the generating cavity.

[0007] Preferably, the inner electrode is bent into shape.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1 — Figure 11An ozone generator includes a housing 1, a generating chamber 2 inside the housing 1, and an ozone generating unit 3 inside the generating chamber 2. The ozone generating unit 3 includes an insulating dielectric plate 31, an inner electrode 32, an outer electrode 33, and a connecting piece 34. The inner electrode 32 is connected to the bottom of the insulating dielectric plate 31, the outer electrode 33 is connected to the top of the insulating dielectric plate 31, one end of the connecting piece 34 is connected to the inner electrode 32, and the other end is bent and connected to the other side of the insulating dielectric plate 31. The insulating dielectric plate 31 is disposed inside the generating chamber 2, and an insulating layer 4 is filled inside the generating chamber 2.

[0018] The generating chamber 2 and the shell 1 are integrated into one piece. Compared with the ozone generator that is directly installed, it can save the space for installation structure and reserved intervals, so that the final size of the product can be reduced and it is easy to install in different usage scenarios.

[0019] Furthermore, such as Figure 3 As shown, an ozone generating unit 3 is provided inside the generating chamber 2. The ozone generating unit 3 specifically includes an insulating dielectric plate 31, an inner electrode 32, an outer electrode 33, and a connecting piece 34.

The insulating dielectric plate 31 is installed inside the generating chamber 2. The inner electrode 32 can be led out from below the insulating dielectric plate 31 through the connecting piece 34 to facilitate wiring operations. In order to further improve assembly efficiency, power lines can be pre-welded to one end of the connecting piece 34 and the outer electrode 33 to facilitate assembly.

[0020] Furthermore, an insulating layer 4 is injected inside the generating cavity 2. The insulating layer 4 is specifically an encapsulating adhesive, which completely fixes the insulating dielectric plate 31, the inner electrode 32, the outer electrode 33, and the connecting piece 34 inside the generating cavity 2.

[0021] like Figure 4 As shown, a slot for the power cord to pass through can also be provided on the outer casing 1.

[0022] This utility model, by directly setting the generating chamber 2 inside the housing 1, eliminates the need for a separate modular installation structure and wiring structure inside the housing 1, thereby reducing the product size. The ozone generating unit 3 set inside the generating chamber 2 encapsulates the inner electrode 32 inside the generating chamber 2 through an insulating dielectric plate 31 and an insulating layer 4. The outer electrode 33 is connected to the insulating dielectric plate 31, and the inner electrode 32 is connected to the insulating dielectric plate 31 through a connecting piece 34. This facilitates wiring operations during assembly and improves assembly efficiency while reducing the product size.

[0028] As a sixth embodiment of the internal electrode 32 provided by this utility model, such as Figure 10 As shown, the internal electrode 32 has a sawtooth structure.

[0029] As a seventh embodiment of the internal electrode 32 provided by this utility model, such as Figure 11 As shown, the inner electrode 32 has an oblique mesh structure.

[0030] It should be noted that the first, second, third, and fourth embodiments of the internal electrode 32 provided by this utility model can be combined with the fifth and fourth embodiments to form the structure provided by the first, second, third, and fourth embodiments in top view, and the structural schematic diagram provided by the fifth and fourth embodiments in side view.

[0031] As an embodiment provided by this utility model, such as Figure 3 and Figure 4 As shown, the generating chamber 2 is provided with an outlet 22 and an inlet 21. The outlet 22 is located outside the housing 1, and the inlet 21 is located inside the housing 1. A connecting chamber 23 is provided at the upper part of the generating chamber 2. The outlet 22 and the inlet 21 are both connected to the connecting chamber 23. The inlet 21 and the outlet 22 are connected through the connecting chamber 23. The inner electrode 32 is embedded inside the connecting chamber 23, so that the gas passing through the connecting chamber 23 can fully contact the inner electrode 32, thereby improving the efficiency of ozone generation.

[0032] As an embodiment of the present invention, an air pump 5 is fixedly installed inside the housing 1. The output end of the air pump 5 is connected to the air inlet 21, and the input end of the air pump 5 is directly connected to the inside of the housing 1.

[0033] As an embodiment provided by this utility model, such as Figure 4 As shown, it also includes a discharge unit 6, which is fixedly installed inside the housing 1. The discharge unit 6 is electrically connected to the inner electrode 32 and the outer electrode 33. Specifically, the discharge unit 6 is directly electrically connected to the outer electrode 33 via a power cord. The discharge unit 6 is electrically connected to the connecting piece 34 located above the insulating dielectric plate 31 via a power cord. Since the connecting piece 34 is electrically connected to the inner electrode 32, the discharge unit 6 is electrically connected to the inner electrode 32. Preferably, a reinforcing rib 13 is also provided inside the housing 1, dividing the interior of the housing 1 into several areas. The air pump 5 is installed in one area, and the discharge unit 6 is installed in another area.

A snap-fit ​​connector 12 is provided on the positioning strip 11. A snap-fit ​​groove 71 is provided on one side of the top cover 7. The top cover 7 can be quickly positioned with the housing 1 through the positioning strip 11 and snap-fit ​​with the snap-fit ​​connector 12 on the positioning strip 11 through the snap-fit ​​groove 71.

[0035] It should be noted that a certain gap is left around the perimeter of the housing 1 and the top cover 7 for air intake. Connecting posts are provided inside the housing 1 and the top cover 7, which can be used to completely fix the housing 1 and the top cover 7 with screws.

[0036] Working principle: In use, the gas is introduced into the connecting cavity 23 through the air inlet 21 by the air pump 5. At this time, the discharge unit 6 discharges through the inner electrode 32 and the outer electrode 33, so that ozone is generated at the inner electrode 32. Through the suction action of the air pump 5, the gas inside the shell 1 is continuously introduced into the air inlet 21 and finally blown out through the air outlet 22.

[0037] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.
