Description

Technical Field

[0001] This utility model belongs to the field of ozone generator technology, specifically an ozone generating tube cap and an ozone generating device. Background Technology

[0002] Ozone (O3) is a highly oxidizing gas widely used in various fields, including air purification, disinfection and sterilization, water purification, and industrial production. In water treatment, it can effectively kill bacteria and viruses, decompose organic matter and heavy metals, and replace traditional chlorine disinfection to avoid secondary pollution. Its preparation technologies mainly include corona discharge, low-pressure hydrolysis, and ultraviolet irradiation. The corona discharge method uses a high-voltage electric field to ionize oxygen and generate ozone.

[0003] CN201520903812.7 discloses a device for sterilizing and decomposing harmful substances in a water storage tank, including an upper cover, a lower cover, and an ozone generator; the lower cover is also provided with a front cover plate and a rear cover plate, and the upper cover and the lower cover form a sealed cavity, in which the sterilization device is housed; the ozone generator includes an aluminum alloy lampshade, a high-power ultraviolet high ozone lamp, a high-power electronic ballast, and a gas pipe device.

[0004] In the above technical solution, when the second vent is located at the end and connected to the first vent through a pipe, the axis of the second vent is perpendicular to the axis of the rear lamp holder. Therefore, when the pipe is connected to the vent pipe, there will be a section with a large degree of bending. When ozone is discharged, it is not conducive to the rapid discharge of ozone. Moreover, the shell needs to reserve more space, and the pipe is in a bent state for a long time, which is prone to material fatigue and thus affects the service life of the pipe.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] refer to Figures 1-4 A cap for an ozone generating tube, the ozone generating tube 1 including an outer electrode tube 11, a dielectric ceramic tube 12 disposed in the outer electrode tube 11 and an inner electrode tube 13 disposed in the dielectric ceramic tube 12, one end of the inner electrode tube 13 being fitted with an air inlet connector 2, and an ionization channel (not shown in the figure) being provided between the dielectric ceramic tube 12 and the inner electrode tube 13.

[0035] The cap 3 includes a hollow column 31. The inner wall of the column 31 is provided with a positioning part 32 and a fitting 33. The positioning part 32 and the fitting 33 are arranged sequentially along the axial direction of the column 31.

[0036] The cap 3 is fitted onto the end of the inner electrode tube 13 away from the air inlet connector 2 by the kit 33, and the end of the dielectric ceramic tube 12 is pressed against the positioning part 32.

[0037] The outer wall of the column 31 is provided with a connecting block 34, and an air outlet pipe 35 is provided on the side of the connecting block 34 near the air inlet connector 2. The axis of the air outlet pipe 35 is parallel to the axis of the column 31.

[0038] The connecting block 34 is provided with a connecting channel 36, and the ionization channel is connected to the gas outlet pipe 35 through the connecting channel 36.

[0039] The structure and positional relationship of the outer electrode tube 11, dielectric ceramic tube 12, inner electrode tube 13, air inlet connector 2, and ionization channel have been disclosed in Chinese patent CN220684691U, so they will not be described in detail in this embodiment.

[0040] In this design, a positioning part 32 and a fitting 33 are provided on the inner wall of the column 31, and the positioning part 32 and the fitting 33 are arranged sequentially along the axial direction of the column 31. During installation, the fitting 33 is used to first put the tube cap 3 into place, and then the positioning part 32 is used to make one end of the dielectric ceramic tube 12 abut against the positioning part 32 to complete the installation of the tube cap 3. Since the gas outlet pipe 35 is located on the side of the connecting block 34 near the gas inlet connector 2, and the axis of the gas outlet pipe 35 is parallel to the column 31, the gas can be directly discharged when the pipe is connected to the gas discharge pipe of the external ozone generator. In this way, the flowability of ozone is improved, which is conducive to the rapid discharge of ozone and saves more space.

[0041] In this embodiment, the vertical cross-section of the connecting channel 36 is L-shaped, and the connecting channel 36 includes a horizontal section 361 and a vertical section 362 disposed within the connecting block 34;

[0042] One end of the horizontal section 361 is connected to the air outlet pipe 35, one end of the vertical section 362 is connected to the horizontal section 361, and the other end extends downward and is connected to the hollow part of the column 31. When the cap 3 is fitted onto the inner electrode tube 13, the end of the vertical section 362 connected to the hollow part of the column 31 is connected to the ionization channel.

[0043] Specifically, the vertical surface of the channel has an L-shaped structure. One end of the horizontal section 361 is connected to the outlet pipe 35, and one end of the vertical section 362 is connected to one end of the horizontal section 361. The other end is connected to the hollow part of the column 31. When the cap 3 is fitted on the inner electrode tube, the end of the vertical section 362 connected to the hollow part of the column 31 will be connected to the ionization channel. The ozone generated after ionization will first pass through the vertical section 362, then through the horizontal section 361, and then be discharged from the outlet pipe 35.

[0044] More preferably, the cap 3 is made of ceramic. Ozone has strong oxidizing properties, therefore the cap 3 is made of ceramic.

[0045] Preferably, both the positioning part 32 and the kit 33 are annular structures, and the inner diameter of the positioning part 32 is larger than the inner diameter of the kit 33.

[0046] Generally, both the inner electrode tube 13 and the dielectric ceramic tube 12 are annular structures. Therefore, the positioning part 32 and the sleeve 33 are set as annular to better fit the sleeve 33 when it is fitted onto the inner electrode tube 13, and the positioning part 32 is used to press the dielectric ceramic tube 12 against each other.

[0047] Example 2

[0048] refer to Figures 5-6 An ozone generating device includes a housing 4 and a cap 3 as described in Embodiment 1. An ozone generating tube 1 is provided inside the housing 4. A heat sink 6 is installed on the ozone generating tube 1. The top of the heat sink 6 is provided with a mounting part 61 for mounting electronic components.

[0049] One end of the housing 4 is equipped with a fan (not shown in the figure), and the other end is equipped with a through hole 41, a gas inlet pipe 42, and a gas outlet pipe 43.

[0050] The ozone generating tube 1 is horizontally disposed inside the housing 4, and the tube cap 3 is sleeved on the end of the ozone generating tube 1 away from the gas outlet pipe 35.

[0051] The air outlet pipe 35 is connected to the gas discharge pipe 43 through a pipe, and the air inlet connector 2 is connected to the gas input pipe 42 through a pipe.

[0052] The structure of radiator 6 has been disclosed in Chinese patent CN215756451U, so the structure of radiator 6 will not be described in detail in this embodiment.

[0053] In this design, the gas used to generate ozone can be either pure oxygen or air. These gases are introduced into the inlet connector 2 through the gas inlet pipe and then enter the ionization channel. The ozone generating tube 1 then ionizes the input pure oxygen or air to produce ozone. The ozone produced passes through the pipe cap 3 and is discharged from the outlet pipe 35. The ozone is then discharged from the gas outlet pipe 43 through the pipe. Since the high temperature environment will decompose the ozone into oxygen, a fan and a radiator 6 are used to cool down the ozone generating tube 1.

[0054] It should be noted here that the electronic components are generally power supplies, used to provide voltage so that ozone can be produced in the ozone process.

[0055] More preferably, it also includes a nut 5, one end of the inner electrode tube 13 is provided with a thread 131, and the nut 5 is connected to the thread 131 to press the tube cap 3 against one end of the dielectric ceramic tube 12.

[0056] Specifically, by using nut 5 to connect with thread 131, the cap 3 and dielectric ceramic tube 12 are more tightly pressed together by screwing in nut 5.

[0057] Preferably, the axes of the gas discharge pipe 43 and the gas outlet pipe 35 are on the same horizontal line. When the gas outlet pipe 35 is connected to the gas discharge pipe 43 through a pipe, the pipe is straighter during installation, allowing for more rapid ozone discharge.

[0058] Generally speaking, the air inlet connector 2 can also adopt the structure of the cap 3 in Embodiment 1.

[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
