Description

Technical Field

[0001] This utility model belongs to the field of ozone generating tube technology, specifically an ozone generator that is easy to install and remove the fan. Background Technology

[0002] Ozone generators are devices used to produce ozone. They use air or oxygen as raw materials and generate ozone through high-frequency, high-voltage discharge. They are widely used in tap water, sewage, industrial oxidation, and space sterilization. However, current ozone generators generally have the following shortcomings: they are usually tank-type or cabinet-type, and are relatively large in size, making them unsuitable for portable use. They are also prone to heat accumulation, which reduces ozone concentration and output.

[0003] CN202123061405.0 discloses a high-yield, long-life ozone generating chamber, comprising a chamber, both ends of which are provided with PTFE end caps, a glass tube and a PTFE wire are provided between the two PTFE end caps, one end of the glass tube is provided with a high-voltage electrode rod, a plurality of heat sinks are uniformly provided on the outer wall of the chamber, and a first air duct cover plate, a second air duct cover plate, an air intake fan and an air exhaust fan are provided on the chamber, and the exterior of the chamber, the first air duct cover plate and the second air duct cover plate are all wrapped with aluminum foil.

[0004] In the above-mentioned technical solution, when installing the fan, it is necessary to fix the fan to the cover plate with bolts. However, this fixing method requires finding bolts that match the mounting holes of the fan and using a screwdriver to complete the installation. Therefore, both installation and disassembly are relatively troublesome. Utility Model Content

[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 1-8 An ozone generator with an easy-to-disassemble fan includes a housing 1, a fan 4 and an ozone generating tube 12. The housing 1 has a detachable front cover 2 and a rear cover 3 at both ends along its length. The ozone generating tube 12 is disposed inside the housing 1. The rear cover 3 is provided with an input end 31 for inputting air into the ozone generating tube 12 and an output end 32 for outputting ozone.

[0035] The fan 4 has a housing 41, and the outer wall of the housing 41 is provided with at least two elastic components 5. The elastic movement direction of the elastic components 5 is the axial direction of the fan 4. The front cover 2 is provided with a circular through hole 21 to accommodate the housing 41. The wall of the circular through hole 21 is provided with grooves 22 corresponding to the elastic components 5. One side of the groove 22 has an opening, which is located on the surface of the front cover 2. The opening allows one side of the groove 22 to communicate with the outside. The length of the opening is less than the length of the groove 22. The elastic components 5 can enter the groove 22 through the opening. At this time, compressing the elastic components 5 can cause the elastic components 5 to move along the length direction of the groove 22 within the groove 22.

[0036] The ozone generating tube 12 has been disclosed in Chinese patent CN220684691U, so the structure of the ozone generating tube 12 will not be described in detail in this embodiment.

[0037] In this design, during assembly, the front cover 2 is first installed at one end of the housing 1. Then, the elastic component 5 of the outer casing 41 of the fan 4 is aligned with the opening of the groove 22 and placed in the groove 22. The worker then presses the outer casing 41 and compresses the elastic component 5, causing it to compress towards the axis of the fan 4. At this time, when the outer casing 41 is rotated clockwise, the elastic component 5 moves along the length of the groove 22 within the groove 22, moving it below the closed end of the groove 22. Afterward, the worker releases the pressure, and the elastic component 5 resets, restoring the outer casing 41 to its original position. The shell 41 is fixed in the circular through hole 21. After the fan 4 is installed, the back cover 3 is installed at the other end of the shell 1 in the length direction. To remove the fan 4, press the fan 4 and rotate the shell 41 counterclockwise so that the elastic component 5 is in the opening of the groove 22. Then remove the fan 4. Air is input into the ozone generating tube 12 from the input end 31. The air is ionized by the ozone generating tube 12 and ozone is output through the ozone generating tube 12. In this way, it is more convenient and faster to install and remove the fan 4.

[0038] It should be noted that the outer casing 41 includes an upper casing 14 and a lower casing 15. After the front cover 2 is bolted to one end of the lower casing 15, the fan 4 is installed into the front cover 2. Then, the connecting lines of the ozone generating tube 12 and the fan 4 are connected respectively. After the lines are connected, the rear cover 3 is bolted to the other end of the lower casing 15. Finally, the upper casing 14 is installed on the lower casing 15 and bolted to the front cover 2 and the rear cover 3. When disassembling the fan 4, after loosening the bolts connecting the upper casing 14 to the front cover 2 and the rear cover 3, the upper casing 14 is removed. Then, the wiring of the fan 4 is disconnected. The outer casing 41 of the fan 4 is pressed and rotated counterclockwise so that the elastic component 5 is in the opening of the groove 22, and the fan 4 can be removed.

[0039] In this embodiment, the groove 22 includes a first groove 221 and a second groove 222 connected together. The opening is located on one side of the first groove 221, and one side of the second groove 222 is closed. Both the first groove 221 and the second groove 222 can accommodate the elastic component 5. The elastic component 5 can be switched between the first groove 221 and the second groove 222 by pressing and rotating the outer shell 41. When the elastic component 5 is located in the first groove 221, the outer shell 41 can be detached from the circular through hole 21. When the elastic component 5 is located in the second groove 222, the elastic component 5 is pressed against the two side walls of the second groove 222 by elastic force, so that the outer shell 41 is fixed in the circular through hole 21.

[0040] Specifically, the opening is located on one side of the first groove 221, and one side of the second groove 222 is closed. When fixing the fan 4, the worker aligns the elastic component 5 with the opening in the first groove 221 and puts it into the first groove 221. Then, the worker presses the outer shell 41 to compress the elastic component 5 towards the axis of the fan 4. Then, the worker rotates the outer shell 41 clockwise to switch the elastic component 5 from the first groove 221 to the second groove 222. Then, the worker releases the outer shell 41, so that the elastic component 5 is reset. The elastic component 5 is pressed against the two side walls of the second groove 222 by elasticity, thereby fixing the outer shell 41 in the circular through hole 21.

[0041] When disassembling fan 4, press the outer casing 41 again and rotate the outer casing 41 counterclockwise to switch the elastic component 5 from the second slot 222 to the first slot 221, and then remove fan 4.

[0042] Preferably, a limiting block 223 is provided at the end of the second groove 222 near the first groove 221. When the elastic component 5 is located in the second groove 222, the limiting block 223 is used to lock the elastic component 5 in the second groove 222.

[0043] The elastic component 5 includes a fixed block 51, a spring 52, and a movable block 53 connected in sequence along the axis of the fan 4. The fixed block 51 is connected to the outer wall of the housing 41, and the spring 52 is used to drive the fixed block 51 and the movable block 53 to press against the two side walls of the second groove 222.

[0044] Specifically, when installing the fan 4, after aligning it with the opening of the first slot 221, and pressing the movable block 53 against the bottom wall of the first slot 221, press the outer shell 41 to compress the spring 52 and rotate the outer shell 41 clockwise to switch the fixed block 51, spring 52 and movable block 53 from the position of the first slot 221 to the second slot 222. Then release the hand, use the spring 52 to reset, and press the fixed block 51 and movable block 53 against the two side walls of the second slot 222 respectively to complete the fixation of the outer shell 41. The limiting block 223 is used to lock the fixed block 51.

[0045] When the fixed block 51, spring 52, and movable block 53 are all in the second groove 222 and the outer shell 41 needs to be disassembled, the outer shell 41 will be restricted by the limiting block 223 when rotating because the end of the second groove 222 is provided with a limiting block 223. Therefore, the outer shell 41 cannot be directly rotated counterclockwise into the first groove 221. In this case, the outer shell 41 must be pressed first, the spring 52 is compressed, and the fixed block 51 is released from the limiting block 223 before the counterclockwise rotation can switch to the first groove 221.

[0046] Preferably, the outer casing 41 has a circular structure, and there are four elastic components 5 arranged along the circumferential direction of the outer wall of the outer casing 41. Generally, the outer casing 41 of the fan has a circular structure, and providing four elastic components 5 can better fix the outer casing 41 in the circular through hole 21.

[0047] Preferably, the outer wall of the outer casing 41 is further provided with guide blocks 54 corresponding to the movable blocks 53 one-to-one. The guide blocks 54 have a T-shaped structure, and the fixed block 51 is slidably connected to the guide blocks 54. Specifically, in order to adapt to the T-shaped structure of the guide blocks 54, the movable blocks 53 adopt a T-shaped through groove and are slidably connected to the guide blocks 54. The guide blocks 54 are used to guide the movement of the movable blocks 53 and improve stability.

[0048] Preferably, one end of the housing 1 is provided with a plurality of first threaded holes, and the other end is provided with a plurality of second threaded holes 13;

[0049] The front cover 2 is provided with a plurality of third threaded holes 23 corresponding one-to-one with the first threaded holes, and the rear cover 3 is provided with a plurality of fourth threaded holes 34 corresponding one-to-one with the second threaded holes 13.

[0050] Furthermore, when fixing the front cover 2 and the rear cover 3, the front cover 2 can be fixed to one end of the housing 1 by using bolts passing through the first threaded hole and the third threaded hole 23, while the other end of the housing 1 can be fixed by using bolts passing through the second threaded hole 13 and the fourth threaded hole 34.

[0051] More preferably, it also includes two circular mesh covers 6, with four locking slots 61 provided along the circumferential direction of the mesh cover 6. Each of the two surfaces of the outer shell 41 is provided with a connecting post 42 corresponding to the locking slot 61. The locking slot 61 and the connecting post 42 cooperate to allow the mesh cover 6 to rotate relative to the outer shell 41, thereby enabling the mesh cover 6 to be locked or removed.

[0052] In this embodiment, the connecting post 42 includes a post body 421 and a post head 422. One end of the post body 421 is connected to the surface of the outer shell 41, and the other end is connected to the post head 422.

[0053] The locking groove 61 includes a material passage hole 612 and a locking slide groove 611. The material passage hole 612 and the locking slide groove 611 are connected. The inner diameter of the material passage hole 612 is larger than the outer diameter of the column head 422. The width of the locking slide groove 611 is larger than the column body 421 and smaller than the outer diameter of the column head 422. The column body 421 can be positioned in the material passage hole 612 or the locking slide groove 611 by rotating the mesh cover 6.

[0054] Specifically, when fixing the mesh cover 6, the worker first aligns the material passage hole 612 of the mesh cover 6 with the column head 422 of the connecting column 42, so that the column head 422 passes through the material passage hole 612, and then rotates counterclockwise so that the column body 421 is located in the locking groove 611. Since the width of the locking groove is greater than the column body 421 and smaller than the outer diameter of the column head 422, the mesh cover 6 will be locked to the surface of the outer shell 41 through the column head 422.

[0055] To remove the mesh cover 6, rotate the mesh cover 6 clockwise so that the column body 421 is located in the material passage hole 612 and the position of the column head 422 corresponds to the position of the material passage hole 612. In this way, the worker can remove the mesh cover 6. This installation method makes it easier for workers to clean the dust from the fan blades of the fan 4.

[0056] Preferably, the housing 1 is provided with a mounting plate 11 for installing electronic components, and the rear cover 3 is also provided with a plurality of heat dissipation holes 33.

[0057] Specifically, the electronic components are generally voltage sources, mainly used to provide voltage to the ozone generating tube 12 to ionize the air. The input terminal 31 and output terminal 32 of the front cover 2 are respectively connected to the two ports of the ozone generating tube 12 through pipes. The input terminal 31 inputs air into the ozone generating tube 12, the ozone generating tube 12 ionizes the air and outputs the generated ozone. The heat dissipation hole 33 is used to cooperate with the fan 4 to better dissipate heat from the ozone generating tube 12.

[0058] 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.
