Description

Technical Field

[0001] The present invention relates to an ozone generator having a deodorizing effect and a sterilizing effect, and particularly to an ozone generating device for deodorization and sterilization in a sealed area such as a refrigerator, a shoe box, a cupboard, a trash can, etc.

Background Art

[0002] Ozone gas (molecular formula: O3) is a gas that always exists in the earth's atmosphere at a low concentration. It can be easily separated into oxygen gas (O2) and oxygen atoms (O), and this oxygen atom has a strong oxidizing power second only to fluorine.

[0003] Utilizing the strong oxidizing power of ozone gas (hereinafter simply referred to as "ozone" in this application), it has been conventionally used for deodorization, sterilization, and virus inactivation. Ozone generating devices for the purpose of deodorization and sterilization in indoor spaces where people live, as well as in sealed spaces such as refrigerators, shoe boxes, cupboards, trash storage bins, etc. are known.

[0004] As an example of such a deodorizing device using ozone, a device that injects mist with a particle size of about 50 nanometers to microns into the room to be deodorized, and additionally injects negative ions, ozone, and vibration energy, and further arranges a ceramic B with adsorption and decomposition ability behind the outside air intake 19, the fan unit 1, and the filter 20 is known (for example, refer to Patent Document 1).

[0005] Also, a purification trash can is known in which the upper lid is installed on the top end surface of the hollow box body so as to be openable and closable by a driving device, and is automatically opened and closed by the sensing function of a sensing sensor and the control of the driving device by a microcomputer. Inside the hollow box body, a purification device composed of one or a combination of two or more of an ultraviolet light, an ozone generator, and a negative ion generator is installed, and the inside of the hollow box body 10 is purified under the control of the microcomputer (for example, refer to Patent Document 2).

[0006] Furthermore, there is also an air conditioning device that includes an ion generator that generates positive ions, negative ions, and ozone, a human body sensor that detects the presence or absence of people in the room, and a mode switching control means that controls the ion generator to switch between a sterilization operation mode that generates positive and negative ions, a relaxation operation mode that generates at least negative ions, and a deodorizing operation mode that generates ozone, based on signals from the human body sensor (see, for example, Patent Document 3).

[0007] Furthermore, as an example of a mechanism for generating ozone, there is a negative ion and ozone generator in which the applied DC high voltage is 7kV-10kV and the discharge distance is 10mm-13mm, and the radius of the circular hole provided in the induction electrode plate is optimized (see, for example, Patent Document 4).

[0008] Furthermore, as an example of using ozone to disinfect and deodorize inside a refrigerator, there is a known disinfection and deodorization device that includes a refrigeration cycle device having a flammable refrigerant, a storage chamber that is reduced to a pressure lower than atmospheric pressure, and a first electrode and a second electrode placed inside the storage chamber to which a voltage is applied, and which decomposes odor components or bacteria contained in the air inside the storage chamber by ozone or negative ions generated by the discharge between the first electrode and the second electrode (see, for example, Reference 5).

[0009] Furthermore, as an example of a device that can generate ozone in addition to negative ions, a negative ion generator 1 is also known, which comprises a discharge electrode 2 having a round rod-shaped body 2a and a conical portion 2b having a sharp tip portion 2c at one end of the body, a ring electrode 3, a shielding cover 4, a DC high voltage generation circuit 5, a variable resistor 6, and a power supply 7, wherein the ring electrode 3 is arranged concentrically parallel to the discharge electrode 2 (see, for example, Patent Document 6). [Prior art documents] [Patent Documents]

[0010] [Patent Document 1] Japanese Patent Publication No. 2012-105707 [Patent Document 2] Utility Model Registration No. 3146752 (Publication) [Patent Document 3] Patent No. 3403723 [Patent Document 4] Japanese Patent Publication No. 2013-222537 [Patent Document 5] Japanese Patent Publication No. 2012-122620 [Patent Document 6] Japanese Patent Publication No. 2013-73865 [Overview of the Initiative] [Problems that the invention aims to solve]

[0011] However, due to its strong oxidizing power, ozone is corrosive and emits a characteristic fishy, ​​pungent odor. Furthermore, in environments where the concentration of ozone exceeds a certain level, it is dangerous for humans and animals to inhale ozone gas above a certain concentration or to have it come into contact with mucous membranes or skin, and should be avoided as much as possible.

[0012] Furthermore, when an ozone generator is used not for the purpose of purifying human living spaces as disclosed in Patent Document 1, but for deodorizing and sterilizing enclosed spaces such as refrigerators, shoe cabinets, cupboards, and garbage storage areas, the ozone generator must have a simple structure, be small and low-cost, and be easy to assemble and manufacture. Moreover, due to various needs such as being installable in places where commercial power is unavailable, being portable, and having a compact design that allows for easy installation of the ozone generator, control circuit, and power source (battery), the ozone generator, control circuit, and power source (battery) must be housed within a single housing in an easily assembled and compact manner.

[0013] Furthermore, while refrigerators, shoe cabinets, cupboards, and garbage storage areas are normally enclosed, sealed spaces into which humans do not normally enter, if the doors or lids separating these enclosed spaces are temporarily opened, the ozone gas inside can escape, come into contact with humans, and be inhaled into the body through respiration.

[0014] Therefore, the ozone concentration emitted by ozone generators used for deodorizing and sterilizing refrigerators, shoe cabinets, cupboards, garbage storage units, etc., must be kept below a predetermined value, and the operation of the ozone generator must be stopped when the doors or lids separating enclosed spaces such as refrigerators are temporarily opened.

[0015] Furthermore, since it is battery-powered, it is necessary to minimize power consumption and extend the battery replacement cycle.

[0016] Furthermore, for the purposes of use described above, it is extremely important that the device be compact in size and that the modules and components constituting the device be assembled easily and quickly in order to reduce manufacturing costs.

[0017] The present invention aims to provide an ozone generator that solves all the various problems required for ozone generators intended for deodorizing and sterilizing refrigerators, shoe cabinets, cupboards, garbage storage units, etc. [Means for solving the problem]

[0018] To solve the above objective, the ozone generator according to the present invention comprises an ozone generator, a control circuit for controlling the ozone generator, a battery for supplying electricity to the ozone generator and the control circuit, and a housing including an ozone emission holder having an emission port for emitting ozone to the outside of the ozone generator, and a bracket and cover for housing components. Openings are provided at both ends of the housing, the bracket is inserted into the housing, an end cap is fitted to one end of the bracket to close one end of the opening, and the cover is detachably connected to the other opening of the housing. The bracket is provided with a first locking position, a second locking position, and a third locking position, each of which fits the ozone generator, the battery, and the ozone emission holder, respectively, and locks them in place. The second locking position is provided with an arc-shaped edge that forms a groove to restrict the vertical position of the battery and fits the arc-shaped surface of the battery. It is characterized by the following.

[0019] Ozone is a substance with excellent properties such as sterilization and deodorization, but high concentrations of ozone are harmful to the human body. Therefore, concentration control is necessary to balance effectiveness and safety when using ozone.

[0020] Therefore, in this ozone generator, when a refrigerator, a shoe box, a cupboard, a garbage bin, etc. are used in a normally closed and sealed space, when a person opens the door of such a sealed space, the opening is surely detected and the generation of ozone is stopped.

[0021] This ozone generator is further equipped with an ozone concentration sensor and a smell sensor, and the operation of the ozone generator is controlled based on the ozone concentration detection value of the ozone concentration sensor and the smell detection value of the smell sensor.

[0022] Here, when the ozone concentration detection value by the ozone concentration sensor exceeds a preset value, regardless of the vibration detection by the vibration sensor and the light quantity detection value by the light sensor, the operation of the ozone generator is stopped or the ozone output concentration of the ozone generator is reduced.

[0023] And when the smell detection value by the smell sensor exceeds a preset value, regardless of the vibration detection by the vibration sensor and the light quantity detection value by the light sensor, the operation of the ozone generator is stopped or the ozone output concentration of the ozone generator is reduced.

[0024] Regarding the toxicity of ozone, in Japan, as the workplace environmental standard concentration recommended by the Japan Industrial Health Association, when the ozone concentration is 0.1 ppm or more, it is defined as a value at which effects on the human body (such as coughing and tearing) occur.

[0025] Since ozone can be said to be a safe substance if its concentration control is correct, in the present invention, when the ozone concentration detection value by the ozone concentration sensor exceeds a preset value, regardless of the vibration detection by the vibration sensor and the light quantity detection value by the light sensor, the operation of the ozone generator is stopped. As the upper limit setting value of this ozone concentration, for example, it is set to 0.05 ppm to 0.1 ppm.

[0026] On the other hand, an important issue that the ozone generator according to the present invention solves is the reduction of manufacturing costs, due to the compact size of the device and the ease and speed of assembly of the modules and components that make up the device.

[0027] To achieve this, the structure of the ozone generator described above is further provided with a first locking position, a second locking position and a third locking position in the bracket, the first locking position, the second locking position and the third locking position respectively fit the ozone generator, the battery and the ozone emission holder, and lock the ozone generator, the battery and the ozone emission holder, and further, the upper and lower sides of the second locking position are provided with opposing arc-shaped sides, the arc-shaped sides fit the arc-shaped surface of the battery, and the arc-shaped sides opposite the upper and lower sides are configured to form a position limiting groove and to contact the battery. [Effects of the Invention]

[0028] With the technical configuration described above, the present invention not only satisfies all requirements such as being small, low-cost, easily movable regardless of installation location, and having low power consumption and a long lifespan, but also realizes an ozone generator that takes into consideration the discomfort and respiratory health damage caused by ozone gas to humans and animals.

[0029] Furthermore, the ozone generator according to the present invention does not require special tools for assembly, significantly reducing assembly time through a very simple assembly process, and its appearance is extremely simple, achieving both functionality and aesthetic appeal. [Brief explanation of the drawing]

[0030] [Figure 1] An example of a configuration diagram for an ozone generator related to the present invention is shown. [Figure 2] This diagram shows a localized disassembled assembly of the ozone generator, which is equipped with hooks that allow it to be easily attached to various locations.

[Figure 9] This shows an example of component mounting on the control circuit board of this ozone generator. [Modes for carrying out the invention]

[0031] An example of an embodiment of the ozone generator according to the present invention will be described in detail below with reference to the drawings.

[0032] Furthermore, the terms used in the description of embodiments illustrating the ozone generator according to the present invention, such as "inside," "outside," "up," "down," "left," and "right," refer to the directions or positional relationships indicated by the drawings, or the directions or positional relationships in which the invention is always positioned when in use. In addition, expressions such as "first," "second," etc., are terms used to identify the parts, etc., related to those terms, and do not indicate relative importance.

[0033] Figures 1-5 illustrate the details of the ozone generator of the present invention.

[0034] This ozone generator includes a housing 1, a bracket 2, and a cover 3. The bracket 2 is inserted into the housing 1, and the cover 3 locks into the housing 1 and the bracket 2.

[0035] Ventilation holes 4 are provided in the side wall of housing 1, and ports are provided at both ends of housing 1. An end cap 6 is provided at one end of bracket 2, and bracket 2 is integrally molded with the end cap 6.

[0036] Bracket 2 is inserted into housing 1, and its end cap 6 locks into one port of housing 1, while cover 3 locks into the other port of housing 1.

[0037] The bracket 2 is detachably connected to the battery 7, ozone generator 8, ozone radiation holder 9, and circuit board 5, and the circuit board 5 is electrically connected to the battery 7 and ozone generator 8, respectively.

[0038] Here, the ozone generator 8 is electrically connected to the ozone radiation holder 9, and by energizing the ozone generator 8 and the ozone radiation holder 9, ozone is generated and can be blown out through the vent 4, thus performing a purification treatment on the air.

[0039] Bracket 2 allows the battery 7, ozone generator 8, ozone emission holder 9, and circuit board 5 to be easily and securely fixed inside housing 1. In other words, when assembling this ozone generator, all that is required is to insert bracket 2 into case 1 and put cover 3 on top; no auxiliary tools are needed, making it very convenient and quick, and also aesthetically pleasing.

[0040] Specifically, as shown in Figure 3, in the ozone generator having the structure described above, the bracket 2 is provided with a first locking position 10, a second locking position 11, and a third locking position 12. Here, the first locking position 10 is a rectangular hole whose structure and size are suitable for the ozone generator 8, and is used to house and lock the ozone generator 8.

[0041] The second locking position 11 is a snap groove 22 whose size and structure are suitable for the battery 7, and is used to lock the battery 7.

[0042] Furthermore, the third locking position 12 is compatible with the structure of the ozone emitter holder 9 and is used to lock the ozone emitter holder 9. When installing, the ozone generator 8 and battery 7 are locked to the first and second locking positions manually only.

[0043] As shown in Figure 3, opposing arc-shaped edges 13 are provided on the upper and lower edges of the second locking position 11. The arc-shaped edges 13 conform to the arc-shaped surface of the battery 7, and the opposing upper and lower arc-shaped edges 13 form a position limiting groove and come into contact with the battery 7. This is used to better limit the position in which the battery 7 locks and to make its fixing more stable.

[0044] Furthermore, as shown in Figure 3, in order to more firmly secure the ozone emission holder 9, screw holes 34 are provided in both the third locking position 12 and the ozone emission holder 9, allowing the ozone emission holder 9 to be more firmly fixed in the third locking position 12 with bolts or screws.

[0045] Specifically, as shown in Figure 3, a first convex block is provided on one end of the bracket 2 opposite the end face, and a groove 15 is provided on the circuit board 5 at a position corresponding to the first convex block. The first convex block locks with the groove 15 to fix the circuit board 5 to the bracket 2.

[0046] Specifically, in this ozone generator, as shown in Figures 3 and 4, a bar-shaped protrusion 16 extending outward is provided at one end of the bracket 2 facing the end face, and a snap-fit ​​17 is provided at a position corresponding to the bar-shaped protrusion 16 on the cover 3. The snap-fit ​​17 is provided with a second protrusion projecting inward, and the snap-fit ​​17 is formed to interlock with the bar-shaped protrusion 16. This allows the cover 3 and the bracket 2 to be detachably connected, and the cover 3 is fixed to one end of the bracket 2, with both ends of the housing 1 being closed by the end caps 6 provided on the cover 3 and the bracket 2.

[0047] Furthermore, as shown in Figures 2 and 3, inclined portions 19 are provided at the tops of the bar-shaped protrusion 16 and the second protrusion. The inclined portions 19 allow the snap-fit ​​17 and the bar-shaped protrusion 16 to lock very easily, making installation convenient.

[0048] Specifically, as shown in Figure 4, this ozone generator is equipped with a light guide plate 20, which is made of a special light-emitting material and is used to display the operating status of the ozone generator.

[0049] Furthermore, the light guide plate 20 is provided with multiple third protrusions 21, and multiple snap grooves 22 are provided at positions corresponding to the third protrusions 21 on the cover 3 and housing 1. The third protrusions 21 lock into the snap grooves 22, serving to fix the light guide plate 20 to the housing 1, and also transmit light, thus serving a display function.

[0050] Specifically, as shown in Figure 4, in this ozone generator, the cover 3 is provided with a circular through-hole 23, and the power button 24 is cylindrical and is fitted and fixed to the cover 3 through the circular through-hole 23. The power button 24 is further provided with elastic wings 25, and the cover 3 is provided with a locking position for locking the elastic wings 25, so that when the power button 24 is fitted into the circular through-hole 23, the elastic wings 25 are locked in the locking position.

[0051] When using this ozone generator, pressing the power button 24 will turn the ozone generator on or off. The installed elastic wings 25 can securely fix the power button 24 to the cover 3. Furthermore, the elastic wings 25 are made of elastic material and have relatively good elasticity, allowing the power button 24 to quickly return to its original position when the finger is released.

[0052] As shown in Figure 2, the battery 7 is a rechargeable secondary battery, and the housing 1 is provided with a charging port 26 at a position corresponding to the circuit board 5, which is used to connect an external power source when charging.

[0053] Preferably, a power cover 27 should be detachably connected to the charging port 26 to prevent water from entering the housing 1 through the charging port 26 when not charging and damaging the circuit board 5.

[0054] Furthermore, as shown in Figure 2, a mounting hole 28 is provided on the side of the housing 1 opposite the ventilation hole, and a connecting component 29 is connected to the mounting hole 28. A clip 30 (shown in Figure 5) is provided on the bottom surface of this connecting component 29, and the clip 30 protrudes into the mounting hole 28 and locks into the mounting hole 28.

[0055] As shown in Figure 5, the top circumference of the connecting component 29 is provided with an outward-extending extension side 31, which is used to lock onto a hook 32, and the hook 32 is used to secure the ozone generator to a refrigerator door or other location where deodorization is needed.

[0056] Furthermore, the hook 32 is provided with a slot 33, which can be inserted into either of the extension sides 31. This connects the hook 32 to the connecting member 29, thereby connecting the hook 32 to the housing 1 of the ozone generator. At the same time, since the two pairs of extension sides 31 provided on the connecting member 29 are mutually orthogonal, the hook 32 can be connected to the housing 1 in both the horizontal and vertical directions, enabling horizontal or vertical suspension of the housing 1 and improving the adaptability of the ozone generator.

[0057] As explained in detail above, this ozone generator allows for very convenient fixing of the circuit board, battery, ozone generator, and ozone emission holder within the housing by installing a detachable bracket, making assembly easy and requiring no special tools, thus greatly improving assembly efficiency.

[0058] Figure 6 is intended to illustrate the ozone generating means that constitute this ozone generator, with part (a) showing the basic principle of the ozone generating means that constitute this ozone generator, and part (b) showing the basic configuration of the ozone generating means that constitute this ozone generator.

[0059] As shown in Figure 6, ozone O3 is generated by introducing oxygen (oxygen from the atmosphere) between electrodes 40A and 40B and applying an alternating voltage between electrodes 40A and 40B to create a so-called silent discharge. Electrons generated between electrodes 40A and 40B by the silent discharge collide with oxygen in the air, causing the oxygen gas O2 to first separate into oxygen atoms 2O. These oxygen atoms O then combine with electrons and oxygen molecules O2 to form ozone O3.

[0060] Here, a dielectric 41 is placed on either one or both of electrodes 40A and 40B to facilitate silent discharge. This makes it possible to generate silent discharge at a relatively low voltage.

[0061] The AC voltage applied between the electrodes is generated by chopping the output voltage (DC) of the battery 7 with a few kilohertz oscillation circuit, applying the chopped voltage to the primary winding of the transformer, and generating it in the secondary winding, which is several tens of times stronger than the primary winding. The inverter circuit that converts the DC voltage to a high-voltage AC voltage is obvious to those skilled in the art and will not be explained in detail here. Incidentally, electrodes 40A and 40B generate some heat depending on the amount of silent discharge, so it is advisable to provide electrodes 40A and 40B with heat sinks, for example, made of aluminum, as shown in Figure 6.

[0062] Incidentally, by silently discharging air in the atmosphere in this way, not only ozone gas but also negative ions are generated simultaneously. The ozone generator according to the present invention is placed in places such as refrigerators, cupboards, and garbage storage rooms, and is not primarily intended for use in human living spaces to release ozone gas and negative ions. Therefore, the beneficial physiological effects of negative ions on humans will not be explained in detail here.

[0063] As mentioned above, ozone gas is a substance with excellent properties such as sterilization and deodorization, but high concentrations of ozone are harmful to the human body. Therefore, concentration control that balances effectiveness and safety is necessary when using ozone.

[0064] Therefore, in the ozone generator according to the present invention, when used in a normally closed, sealed space such as a refrigerator, shoe cabinet, cupboard, or garbage storage unit, if a person or animal pet opens the door or lid that closes the sealed space in which the device is placed, the device is designed to reliably detect the opening and stop the generation of ozone.

[0065] Therefore, in this ozone generator, (as shown in Figure 9) for example, a light sensor S1, a vibration sensor S2, an ozone concentration sensor S3, and an odor sensor S4 are mounted on the circuit board 5, and the operation of the ozone generator 8 is accurately controlled based on the detection values ​​of the light sensor S1, vibration sensor S2, ozone concentration sensor S3, and odor sensor S4.

[0066] Here, the optical sensor S1 and vibration sensor S2 are sensors used to detect whether the doors of the enclosed space where the ozone generator is placed, such as a refrigerator, shoe cabinet, cupboard, or garbage storage unit, are open or closed. When the doors or lids of these refrigerators, etc., are closed, the ozone generator 5 performs ozone generation, and when the doors are opened, the ozone generator 5 stops performing ozone generation.

[0067] On the other hand, the ozone concentration sensor S3 stops the ozone generation operation by the ozone generator 5 if the ozone concentration in the sealed space such as a refrigerator in which the ozone generator is placed exceeds a predetermined value, regardless of the detected values ​​of the light sensor S1 and vibration sensor S2 mentioned above. If the ozone concentration is below the predetermined value, the ozone generator 5 starts generating ozone. Here, the predetermined value of the ozone concentration may be, for example, 0.05 ppm to 0.1 ppm.

[0068] Furthermore, the odor sensor S4 stops the ozone generation operation of the ozone generator 5 when the odor concentration in the sealed space such as a refrigerator in which the ozone generator is placed falls below a predetermined value, regardless of the detection values ​​of the light sensor S1 and vibration sensor S2 mentioned above. If the odor concentration is above the predetermined value, the ozone generator 5 starts generating ozone. Here, the odor concentration setting value of the odor sensor S4 that stops the operation of the ozone generator 5 should be, for example, a level at which a human being can hardly perceive the odor.

[0069] Figures 7 and 8 show examples of on / off operation control of the ozone generator 8 in the ozone generator according to the present invention.

[0070] Figure 7 shows an example of the operation control mode (operation mode 1) of the ozone generator 8 in this ozone generator. This mode (operation mode 1) detects the opening and closing of doors such as refrigerators and shoe cabinets by comprehensively judging the detected values ​​of the optical sensor S1 and the vibration sensor S2, and controls the ON / OFF status of the ozone generator 8 accordingly.

[0071] In Figure 7, first, when the power button 24 is pressed (S11), the ozone generator 8 is activated (S12). Next, if the ozone concentration detected by the ozone sensor S3 is less than or equal to a predetermined value (for example, set to a range of 0.05 ppm to 0.1 ppm), the operation of the ozone generator 8 continues (S13). Also, if the ozone concentration detected by the ozone sensor S3 is greater than or equal to a predetermined value, the operation of the ozone generator 8 continues (S13, S16).

[0072] Subsequently, while the ozone generator 8 is still operating, if the vibration sensor S2 detects vibrations caused by opening the door (S14) and the light intensity detected by the light sensor 15 increases, it is determined that the door or lid of the sealed space has been opened (S15), and the operation of the ozone generator 8 is stopped (S16).

[0073] If the vibration sensor S2 detects vibration and the light intensity detected by the light sensor 15 increases, it means that light has entered the sealed space from the outside, causing the door or lid of the sealed space to be opened. If the vibration sensor S2 detects vibration but the light sensor 15 does not detect any increase in light intensity, it can be assumed that the vibration is caused by human walking or wind.

[0074] Then, if a certain amount of time has elapsed since the ozone generator stopped operating (S16) (S17, S18), the ozone generator 8 is restarted (S12), and the control operations S13 to S18 are performed again.

[0075] Figure 8 shows an example of the operation control mode (operation mode 2) of the ozone generator in this ozone generator. Unlike the example of operation control mode (operation mode 1) described in Figure 7, "operation mode 2" is the operation control mode when an odor sensor S4 is provided in addition to the ozone concentration sensor S3.

[0076] In Figure 8, when the power button 24 is pressed first (S11), the ozone generator 8 is activated (S12).

[0077] Next, if the odor detection value of the odor sensor S4 is above a predetermined set value, the operation of the ozone generator 8 continues; if it is below the set value (S13-1), the operation of the ozone generator 8 is stopped (S16).

[0078] Then, if the odor detection value of the odor sensor S4 is above a predetermined set value and the ozone generator 8 continues to operate, the ozone concentration detection value of the ozone sensor S3 is checked. If the ozone concentration detection value is below a predetermined value (for example, set to a range of 0.05 ppm to 0.1 ppm), the ozone generator 8 continues to operate. If the ozone concentration detection value is above the predetermined value, the ozone generator 8 stops operating (S13-2).

[0079] If the ozone concentration detected by the ozone sensor S3 is below a predetermined value and the ozone generator 8 continues to operate, if the vibration sensor S2 detects vibration caused when the door is opened (S14), or if the light intensity detected by the light sensor 15 increases, it is determined that the door or lid of the sealed space has been opened (S15), and the operation of the ozone generator 8 is stopped (S16).

[0080] As described above, if the vibration sensor S2 detects vibration and the light intensity detected by the light sensor 15 increases, it means that light has entered the sealed space from the outside, causing the door or lid of the sealed space to be opened. If the vibration sensor S2 detects vibration but the light sensor 15 does not detect any increase in light intensity, it can be assumed that the vibration is due to human walking or wind.

[0081] Then, if a certain amount of time has elapsed since the ozone generator stopped operating (S16) (S17, S18), the ozone generator 8 is restarted (S12), and the control operations S13 to S18 are performed again.

[0082] Figure 9 shows an example of component mounting on the circuit board 5 (Figures 3 and 4) of this ozone generator. As shown in Figure 9, a light sensor S1, a vibration sensor S2, and an ozone concentration sensor S3 are mounted on the circuit board 5, and the operation of the ozone generator 8 is accurately controlled based on the detected values ​​of the light sensor S1, vibration sensor S2, and ozone concentration sensor S3 (Figures 7 and 8).

[0083] As explained in detail above, this ozone generator not only meets all requirements such as being small, low-cost, easily portable regardless of installation location, and having low power consumption and a long lifespan, but it also realizes an ozone generator that takes into consideration the discomfort and respiratory health damage caused by ozone gas to humans and animals.

[0084] Furthermore, this ozone generator does not require any special tools for assembly, significantly reducing assembly time through a very simple assembly process. Its appearance is also extremely simple, achieving both functionality and aesthetic appeal. [Explanation of Symbols]
