Description

Technical Field

[0001] The present invention relates to the technical field of low-temperature disinfection by xenon excimer light-excited oxygen to generate active oxygen (or xenon excimer ozone). The invention relates to a xenon excimer light-excited oxygen-generated active oxygen cluster low-temperature disinfection device and an ultrasonic atomization humidification device, and a xenon excimer light source active oxygen cluster ultrasonic atomization water tank is disposed on the disinfection machine. The xenon excimer light source active oxygen cluster ultrasonic atomization disinfection machine can be widely used in the fields of air disinfection and purification and object surface disinfection, and is a new type of efficient and environmentally friendly disinfection and purification equipment. Background Art

[0002] The 172nm deep ultraviolet light emitted by the xenon excimer has a radiation energy of 164kcal / mol, which can cut the double bonds of oxygen molecules to form ground-state oxygen atoms and cut the hydroxyl bonds of water molecules in the air to form hydrogen free radicals and hydroxyl free radicals. Under the condition of air as the gas source, the photochemical products of the xenon excimer light source are ground-state oxygen (O) and ground-state hydroxyl free radicals (OH·), which directly cleave all the main molecular bonds of harmful microorganisms for high-intensity disinfection, and also quickly combine with moisture in the air to extend and generate hydrated superoxide anion clusters (O 2 - (H 2 O) n ), hydrated trioxide anion clusters (O 3 - (H 2 O) n ), hydrated hydroxide ion clusters (OH - (H 2 O) n ), these hydrated ion molecular clusters also have a strong disinfection effect, and have a longer lifespan than ground state oxygen and ground state hydroxyl radicals, ensuring a stable disinfection effect on harmful microorganisms. As we all know, harmful microorganisms belong to organic compounds. The photochemical disinfection active substances generated by the xenon excimer light source to excite oxygen and water in the air have a killing mechanism for harmful microorganisms by oxidizing harmful microorganisms into carbon dioxide gas, water and oxygen, so it has a spectral bactericidal effect. Compared with low-pressure mercury lamps that can emit 185nm, xenon excimer light sources have high luminous efficiency and lower power consumption, and the light source and excitation power supply are small in size, and are suitable for a wide range of temperature and humidity, so they can be conveniently used in many occasions where air disinfection is required. Xenon excimer light sources have good electrical controllability and can be "turned on and off in seconds". Using this electrical characteristic, the amount of active disinfection substances produced by the xenon excimer light source to excite oxygen and water can be accurately controlled according to the needs of disinfection. This is the characteristic guarantee that the xenon excimer light source low-temperature disinfection technology can achieve "human-machine coexistence" air disinfection.

[0003] The energy required to break the triple bond of nitrogen molecules is 225kcal / mol. Since the 172nm radiation energy emitted by xenon excimers cannot meet the bond energy of nitrogen, the photochemical disinfection substances produced by the xenon excimer light source exciting the air are different from the electrochemical disinfection substances produced by the high-voltage electric field discharge ionization in the air. There is no nitrogen element involved in the electrochemical products of the xenon excimer light source, and no harmful nitrogen oxides and high concentrations of positively charged nitrogen cations and negatively charged oxygen ions will be produced. We can call them "active oxygen clusters". The electrochemical disinfection substances produced by air discharge ionization have the participation of nitrogen elements, which can form nitrogen oxides and a large number of positively charged nitrogen cations and negatively charged oxygen ions. If it is used in situations where "humans and machines coexist", it will be harmful to the human body. For the disinfection active substances produced by air discharge ionization, we can still continue the traditional name and call it "ozone".

[0004] As can be seen from the above, the mechanism and chemical composition of the active oxygen clusters produced by the excitation of air by xenon excimer light source are different from those of ozone produced by air discharge ionization in a high-voltage electric field. It is a new third-generation low-temperature disinfection technology. However, the technical regulatory laws and regulations of any country are based on existing technical products. In other words, from the perspective of management, technical regulations lag behind technological progress. Xenon excimer low-temperature disinfection technology is currently facing a state where technology is ahead of regulations. China's national standard GB28232-2020 "Sanitary Standard for Ozone Disinfectors" divides the methods of ozone preparation into three types: dielectric barrier discharge (i.e., air ionization discharge), ultraviolet radiation, and water electrolysis. The gas source of dielectric barrier discharge is divided into air source and oxygen source. Since the cost of using oxygen with a purity of more than 99% as the gas source for dielectric barrier discharge is too high, the dielectric barrier discharge ozone preparation technology is basically based on air source and molecular sieve oxygen generator. The purity of oxygen is about 90% to 92% as the gas source in actual applications, which will breed nitrogen oxides. GB28232 stipulates that the content of nitrogen oxides in ozone produced by dielectric barrier discharge shall not exceed 2.5% of the ozone content. Despite such a control limit on nitrogen oxides, nitrogen oxides will grow at the same time because nitrogen is involved in the electrochemical process. Since nitrogen-containing compounds are more stable than oxygen ions, they will eventually form nitric acid molecules (HNO 3) is the main end product. GB28232 stipulates that the method of preparing ozone can be to electrolyze water to obtain ozone. The water used should generally be pure water. Otherwise, if pure water is not used, inorganic dielectric compounds will soon appear on the electrodes and deposit on the electrodes, which will quickly destroy the electrodes. Since there is no nitrogen-containing component in water, the ozone obtained by electrolyzing water has high energy consumption and it is difficult to obtain ozone gas with a sufficiently high concentration, which limits the widespread promotion and application of the technology of preparing ozone by electrolyzing water. GB28232 stipulates a method for preparing ozone by ultraviolet radiation. The principle is that a low-pressure mercury lamp can emit a light source spectrum of 185nm, and the spectral energy of the low-pressure mercury lamp is higher than the bond energy of oxygen and water molecules. The photochemical products after irradiation of the air are exactly the same as the photochemical products after the xenon excimer spectrum is irradiated into the air. The only pity is that the spectral radiation energy of 185nm emitted by the low-pressure mercury lamp is lower than the spectral radiation energy of 172nm emitted by the xenon excimer light source, so the photochemical capacity of the low-pressure mercury lamp is 20-50 times lower than that of the xenon excimer light source.

[0005] As can be seen from the above, although GB28232 includes the preparation method of the photochemical products of ultraviolet radiation, it does not distinguish between ozone and reactive oxygen clusters. Based on this, the patent application document and all the patent documents that have been applied for and authorized by the applicant and are related to the xenon excimer light source low-temperature disinfection technology, do not distinguish between ozone and reactive oxygen clusters in name, and most of them use the name of ozone instead of reactive oxygen clusters. The confusion of these name applications is based on the constraints of existing technical regulations and the research process of the inventor on the xenon excimer light source low-temperature disinfection technology from shallow to deep, but it does not mean that the inventor confuses two completely different disinfection technologies. Therefore, when describing the present invention, the present invention still uses the expression of "xenon excimer light source reactive oxygen clusters" according to the existing technical regulations GB28232, which is also conducive to the technical inertia of the patent application proposed by the inventor this time and the numerous patent applications proposed by the inventor's research team. However, it must be noted that xenon excimer reactive oxygen clusters and electric field air ionization ozone are two disinfection active substances with significant differences in components. The technical regulations of any country and government have the defect of lagging behind the development of new technologies. For example, GB28232-2020 "Hygiene Requirements for Ozone Disinfectors" promulgated by my country collectively refers to the electrochemical products after air ionization, the photochemical products after ultraviolet radiation, and the electrochemical products after water electrolysis as "ozone", which is a technological backwardness that is inconsistent with objective facts. 3 The ozone represented does not exist in nature. The main component of the terminal molecular ion clusters of the electrochemical products after air ionization is the hydrated nitrate ion cluster (NO 3 - (H2 O) n ), the ultraviolet light required for ultraviolet radiation of air must be vacuum ultraviolet light (VUV) with a wavelength shorter than 200nm, and the terminal ion molecular clusters of its photochemical products are active oxygen clusters. Water electrolysis is divided into two types of electrolytic cells: diaphragm and non-diaphragm electrolytic cells. The products of electrolysis in electrolytic cells with diaphragms are hydrogen and oxygen, and the products of electrolysis in electrolytic cells without diaphragms are "Brown gas". Hydrated nitrate ion clusters, active oxygen clusters, hydrogen, oxygen, and Brown's gas have different main components and very different physical and chemical properties. When used in the disinfection and medical fields, some characteristics are similar, and some characteristics are very different, especially in terms of safety and effectiveness. Therefore, the products after air ionization, ultraviolet radiation, and water electrolysis are classified in the technical regulations GB28232-2020 "Hygiene Requirements for Ozone Disinfectors" for technical management, which is not rigorous, has inaccurate technical definitions, and is inconsistent with objective facts. This is because when the standard was formulated, there was a serious lag between the standard technology and the development of practical technology. It is a technical regulation that urgently needs to upgrade the standard technology. However, no matter what the technical level of the promulgated technical regulations is, as long as they are not abolished, from the perspective of technical management, they have a valid legal status. When expressing technology and registering products, they must be implemented in accordance with the existing technical regulations. Therefore, in the process of the inventor's research on xenon excimer low-temperature disinfection technology, the inventor's technical team used the names of "xenon excimer ozone" and "active oxygen clusters". The inventor hereby reiterates that in the patent application documents that the inventor has submitted and will submit in the future, the meanings of "xenon excimer ozone" and "active oxygen clusters" are the same.

[0006] Around the xenon excimer light source low-temperature disinfection technology, the inventor has filed a series of patent applications, including: 202010875608.4, 202010867969.4, 202021830130.5, 202021830451.5, 202021830453.4, 202021830455.3, 202021830126.9, 20202 1830292.9, 202021830127.3, 202110317294.0, 202110317295.5, 202110317293.6, 202120601537.9, 202120601539.8, 202120601678.0, 202120601677.6, 202120601540.0.

These patent applications filed on the same day have similarities in some technical features with the technical features described in this patent application, but as a complete technical solution, they have different technical features, so they were filed on the same day. Summary of the invention

[0007] There are currently four ways to humidify indoor air. The first is the wet curtain humidification method. The principle is that the fan blows the moisture on the wet curtain to the indoor space in the form of water molecules. The advantage of this humidification method is that the water molecules can be quickly dispersed into the indoor space, and the humidification effect is good. The second is the ultrasonic atomization humidification method. The principle is that the fan blows the tiny water droplets generated by ultrasonic atomization into the indoor space. The disadvantage of this humidification method is that the diffusion distance of the small water droplets of ultrasonic atomization is short, so the effect of indoor humidification is far lower than that of the water curtain. However, a micro-mist of small water droplets can be formed at the injection port of the disinfection machine. This micro-mist formed by small water droplets and xenon excimer active oxygen clusters are very beneficial for the disinfection of local object surfaces. The third is to use a two-fluid nozzle for micro-mist spraying humidification under the action of an air pump. At present, this method is widely used in chemical disinfectant spraying equipment, such as hydrogen peroxide disinfection machines. The fourth humidification method is water vapor humidification. Water droplets are added to the heating plate to generate water vapor, and the fan quickly blows the water vapor generated on the heating plate into the heated space. This humidification method is generally used in central air-conditioning systems or some equipment that needs to humidify small spaces because it requires an electric heater. Therefore, in the current market of civilian humidifiers, the main humidification methods used are water curtain humidification and ultrasonic atomization humidification. The present invention combines ultrasonic atomization humidification with xenon excimer light source low-temperature disinfection technology to design a new type of disinfection device that can disinfect and humidify the air in a local space, and also uses ultrasonic atomized water mist to disinfect the surface of objects. Among them, surface disinfection mainly refers to the surface disinfection of hands, feet and handheld materials (such as fruits, vegetables, toys and other items). One of the technical features in the basic design method of the xenon excimer light source active oxygen cluster ultrasonic atomization disinfection machine is that the xenon excimer light source active oxygen cluster ultrasonic atomization disinfection machine is composed of four basic units: an equipment cabin equipped with a xenon excimer active oxygen cluster excitation cabin, a blower cabin, an ultrasonic atomization humidification cabin and a water tank. When these four basic units are combined with each other, the equipment cabin equipped with a xenon excimer active oxygen cluster excitation cabin and the blower cabin are always located below the ultrasonic atomization humidification cabin. There are two basic modes when the equipment cabin, the blower cabin and the ultrasonic atomization humidification cabin equipped with the xenon excimer active oxygen cluster excitation cabin are combined with the water tank. One is that the water tank is located below the equipment cabin, the blower cabin and the ultrasonic atomization humidification cabin equipped with the xenon excimer active oxygen cluster excitation cabin, which is called the lower design method. The other is that the water tank is located above the equipment cabin, the blower cabin and the ultrasonic atomization humidification cabin equipped with the xenon excimer active oxygen cluster excitation cabin, which is called the upper design method. In the upper design method, the equipment cabin and the blower cabin can be combined into one cabin, while in the lower design method, the equipment cabin and the blower cabin must be separated to form two isolated cabins.One of the technical features of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine designed by the present invention using the upper design method is that in the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine, the equipment cabin and the blower cabin equipped with the xenon excimer active oxygen cluster excitation cabin are always located below the ultrasonic atomization humidification cabin, the water tank is installed above the ultrasonic atomization humidification cabin, and the blower cabin and the equipment cabin can be combined into one cabin, or separated to form two isolated cabins.

[0008] The second technical feature of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine is that the main components of the equipment cabin and the air supply fan cabin used by the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine are composed of a xenon excimer active oxygen cluster excitation cabin, a float-type water valve, and an air supply fan, wherein the fan can be a turbine fan, a blower, or an axial flow fan; the main components of the ultrasonic atomization humidification cabin used by the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine are composed of the airflow duct of the air supply fan and an ultrasonic atomization sheet (or transducer); (Here, it is necessary to make necessary technical explanations for the ultrasonic atomization sheet (or transducer): The full name of the ultrasonic atomization sheet is "ultrasonic transducer", which is a device that converts electromagnetic energy into mechanical energy (sound energy), usually made of piezoelectric ceramics or other magnetostrictive materials. Its working principle is to use the piezoelectric effect of the material to convert electrical signals into mechanical vibrations. Specifically, when the electrical signal When acting on piezoelectric materials, the material will deform, thereby generating ultrasonic waves. Conversely, when ultrasonic waves act on piezoelectric materials, the material will return to its original state, thereby generating electrical signals. The application field of ultrasonic transducers is medical diagnosis: such as B-ultrasound probes, used for medical imaging diagnosis. Industrial cleaning: ultrasonic cleaners, used to efficiently clean various items. Atomizer: Ultrasonic atomizer, used to convert liquid into mist. Scientific research and testing: In the field of scientific research, ultrasonic transducers are often used to measure the size, structural shape and position accuracy of objects, etc. In this application, the atomizer field of ultrasonic transducers is used. In the field of atomizers, "ultrasonic transducers" are generally referred to as "ultrasonic atomizers", or will be referred to as "transducers". It should be pointed out that only when it is clearly stated that the "ultrasonic transducer" is in the fields of medical diagnosis, ultrasonic cleaning, atomizers, ultrasonic measurement, etc., can it be called a "transducer". This is common sense for technicians in the field). The main components of the water tank used in the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine are composed of an aeration head (or tubular aeration head, titanium aeration head), a solenoid valve, and a water level detection sensor.

[0009] The third technical feature of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine is that the base of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine can be a self-moving base with a position cruising function, which is also called a robot base, or it can be a universal wheel or a support base. The universal wheel base can be pushed by manpower, while the support base is fixed in a certain position and cannot be moved.

[0010] The fourth technical feature of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine is that the ozone gas prepared by the xenon excimer light source active oxygen cluster preparation device is transported in two ways. One way is directly transported to the water tank of the ultrasonic atomization humidification cabin. After a part of it is dissolved in the water, the ozone overflowing from the water is sent into the air flow drainage cover (or dome) at the top of the water tank through the air duct under the push of the air supply fan, and is sent out of the spray port of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine through the pipe under the action of the fan. One way is directly sent into the water in the water tank. After a part of it is dissolved in the water, the overflowing ozone gathers in the air flow drainage cover (or dome) at the top of the water tank. After the ozone from the ultrasonic atomization cabin and the ozone from the water in the water tank converge in the air flow drainage cover (or dome), the air supply fan is sent out of the spray port of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine through the pipe together with the ultrasonic atomized water mist.

[0011] The purpose of the xenon excimer active oxygen cluster gas delivery route design in the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine is to form a certain concentration of ozone water in the water tank to prevent the growth of harmful microorganisms such as mold in the water tank. Another purpose is to dissolve ozone in water in advance, so that there will be a certain ozone concentration in the small water droplets of the water mist formed during ultrasonic atomization, and thus the amount of ozone in the ultrasonic atomization water mist can be stabilized and increased, thereby stabilizing the ozone water mist for better disinfection ability.

[0012] The fifth technical feature of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine is that the xenon excimer active oxygen clusters in the ultrasonic atomization water mist released by the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine can change the concentration rapidly under the control of switches or voice control, and can form a water mist with a lower ozone concentration, which has a disinfection and purification effect on the surrounding air; it can form an ozone water mist with a higher ozone concentration for a short time, and disinfect the surface of objects (such as hands, feet and other surfaces) with ozone water mist. At the same time, an ozone concentration sensor should be designed. When the ozone concentration around the xenon excimer light source active oxygen cluster ultrasonic atomization disinfection machine exceeds 0.1mg / m 3 -0.16mg / m 3When the xenon excimer light source is turned off, an alarm is sounded. At present, there is no dedicated active oxygen cluster concentration sensor for active oxygen clusters. The technical team of the present invention has found that the active oxygen clusters generated from photochemical products and ozone generated from electrochemical products have similar strong oxidizing properties, and the components contain O 2 - (H 2 O) n (hydrated superoxide anion clusters), O 3 - (H 2 O) n (hydrated trioxide ion cluster), OH - (H 2 O) n (hydrated hydroxide ion clusters), so in view of the current situation that it is not technically possible to realize a concentration sensor specific for reactive oxygen clusters, an ozone concentration sensor is selected to detect the concentration of reactive oxygen clusters. After experimental verification by the technical team of the present invention, the sensitivity and linearity of the existing ozone concentration sensor for detecting the concentration of reactive oxygen clusters are the same as those for detecting the electrochemical product ozone, but it does not have the specific detection ability to distinguish between reactive oxygen clusters and ozone, nor does it have the specific ability to distinguish the Brownian gas produced by water electrolysis, but it has the specificity of being insensitive to oxygen and hydrogen. Therefore, an ozone concentration monitor was selected as the technical solution for monitoring the concentration of reactive oxygen clusters in this technical solution. Based on this, in the document description of the present invention, the technical meanings of "ozone sensor", "ozone concentration sensor", "reactive oxygen cluster sensor", and "reactive oxygen cluster concentration sensor" are all the same, and all refer to "ozone concentration sensor".

[0013] The xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine can be designed as a fixed, mobile, or automatically cruise mobile disinfection equipment. In this way, it can be widely used in indoor places (such as classrooms, shopping malls, waiting rooms, airport lounges, conference rooms and other indoor places) and indoor doorways in a fixed or mobile or automatically cruise mobile manner as needed to carry out fixed or mobile disinfection and humidification operations on indoor air, and take into account the surface disinfection of hands, feet, and handheld materials (such as fruits, vegetables, toys and other items). Among the fixed, mobile and automatically cruise mobile designs, the preferred technical design scheme for the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine should be the automatic cruise mobile design, which can be commonly referred to as the "xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine robot."

DETAILED DESCRIPTION

[0019] The present invention has been described in detail above. Obviously, those skilled in the art may make many modifications and variations after becoming familiar with the present invention without departing from the spirit and scope of the present invention.

[0020] Example 1: The applicant's scientific research team described a design of a "centrally transmitted xenon excimer light source active oxygen cluster generator" in patent application document 202010875608.4. The practicality of this design is to use the xenon excimer light source to excite the oxygen in the air to produce active oxygen (ozone) to form a continuous xenon excimer active oxygen cluster airflow with disinfection activity. In the design of the xenon excimer active oxygen cluster ultrasonic atomization disinfector, it is also necessary to use the design technology described in patent application document 202010875608.4. In order to more accurately describe the basic design method of the xenon excimer light source active oxygen cluster ultrasonic atomization disinfector, it is necessary to use the design of a specific xenon excimer light source active oxygen cluster ultrasonic atomization disinfector to describe it. To this end, borrowing the design described in patent application document 202010875608.4, a xenon excimer active oxygen cluster generating cabin suitable for the xenon excimer active oxygen cluster ultrasonic atomization disinfector is designed. Figure 1This is actually a type of concentrated transmission xenon excimer light source active oxygen cluster generator described in patent application document 202010875608.4.

[0021] exist Figure 1 In the figure, A is used to represent the entire module component of the xenon excimer reactive oxygen cluster excitation chamber, which is enclosed by a solid frame line. Figure 1 In the figure, A1 is an air pump (denoted by F), F can be a small air compressor, a vortex fan, a blower, or an axial fan, the purpose of which is to provide a power source. A2 is a xenon excimer lamp, A3 is an ozone excitation chamber where the xenon excimer lamp is placed, 9 is an ozone gas pipeline, 5 is an aeration head (tubular aeration head), B is the air inlet of the air pump (which can also be regarded as the air inlet of the xenon excimer active oxygen cluster excitation chamber), and G is a three-way connection. Its working principle is to start the air pump A1 and light up the xenon excimer lamp A2 at the same time. The air entering the air pump from the air inlet of the air pump enters the ozone excitation chamber A3 where the xenon excimer lamp is placed under the action of the air pump, and an airflow is formed around the xenon excimer lamp A2. At this time, the 172nm narrow-band deep ultraviolet light emitted by the xenon excimer lamp excites the oxygen molecules and water molecules in the air flowing around the lamp to form ground state oxygen (O) and ground state hydrogen (H·) and hydroxyl free radicals (HO·), thereby forming a xenon excimer active oxygen cluster gas flow with strong oxidizing properties. The xenon excimer active oxygen cluster gas flow is divided into two streams through the pipeline 9 and the tee G. One of the streams needs to be transported to water. In order to increase the solubility of the xenon excimer active oxygen cluster gas in water, an aeration head 5 is designed in the pipeline. The function of the aeration head is to immerse a stream of xenon excimer active oxygen cluster gas in the form of small ozone bubbles into water, which is very conducive to the dissolution of xenon excimer active oxygen clusters in water.

If the upper design method of a xenon excimer light source active oxygen cluster ultrasonic atomization disinfector is used to design a xenon excimer light source active oxygen cluster ultrasonic atomization disinfector, it is generally recommended to use the gravity of the water in the upper water tank to use a float-type water valve to inject water into the ultrasonic atomization humidification cabin.

A represents the xenon excimer active oxygen cluster excitation cabin; B represents the air inlet direction of the air inlet of the xenon excimer active oxygen cluster excitation cabin; C represents the air inlet direction of the air inlet window of the ozone cabin; D represents the air supply cabin; E represents the equipment cabin.

[0027] First of all, it should be noted that Figure 5 In the figure, the fan cabin (D) and the equipment cabin (E) are separated by a dotted line, which means that in the upper design method of the xenon excimer light source active oxygen cluster ultrasonic atomization disinfection machine, the fan cabin (D) and the equipment cabin (E) can be designed as one cabin. Figure 2 , 3 , 4 and the above description can clearly show how the water in the water tank is added to the water tank of the ultrasonic atomization humidification cabin when the water tank is in the upper position of the ultrasonic atomization humidification cabin. In order to save space, this application will not be repeated.

[0028] exist Figure 5In the design, the xenon excimer active oxygen cluster gas prepared by the xenon excimer active oxygen cluster excitation chamber is transported to the ultrasonic atomization humidification chamber (23) and the water (4) in the water tank (3) through the exhaust pipe (ozone pipe) 8 of the xenon excimer active oxygen cluster excitation chamber in two ways; the distribution ratio of the airflow can be adjusted according to the situation by the airflow regulating valve 2. The reason for passing the ozone gas into the water tank is to suppress the growth of microorganisms in the water tank by dissolving a part of the ozone gas in the water of the water tank. The growth of microorganisms in the water tank, especially the growth of mold, is a shortcoming of many humidifiers at present. Spraying the water vapor mist containing mold or mold spores into the indoor space as a humidified water vapor mist is very harmful to health. Another part of the ozone gas is directly sent to the water tank of the ultrasonic atomization chamber, and the purpose of doing so is also to suppress the growth of microorganisms in the ultrasonic atomization water tank. However, the solubility of ozone in water is limited. The ozone gas escaping from the ultrasonic atomization chamber is blown to the air flow guide cover (or dome) 22 on the top of the water tank by the air supply fan 11 through the ventilation pipe 28 that leads to the top of the water tank (the part above the water surface) through the ultrasonic atomization humidification chamber together with the ultrasonic atomization water mist generated by the ultrasonic atomization sheets 18 and 25. Here, after reuniting with the ozone gas escaping from the water tank, it continues to be sent out through the ozone water vapor mist pipe 21 and the elbow 19 of the ozone water vapor mist pipe under the action of the air supply fan, forming ozone water vapor mist 20 at the nozzle mouth, which is sprayed into the surrounding space to disinfect, purify and humidify the surrounding space with xenon excimer active oxygen clusters.

[0029] Depend on Figure 5 It can be seen that since 6 is marked as an automatic cruise mobile base (or robot chassis), this is a design of a xenon excimer active oxygen cluster ultrasonic atomization disinfection robot with a water tank on top. Figure 5 By analogy, if 6 is replaced with a foot base or a universal wheel base, then Figure 5 The design can be transformed into a xenon excimer active oxygen cluster ultrasonic atomization disinfection machine with a fixed or movable water tank on top. This is an analogy design that is clear to technicians in the professional field.

[0030] exist Figure 5In the design, it is inevitable to digitally control the active components inside the xenon excimer light source active oxygen cluster ultrasonic atomizing water tank upper disinfection machine. It is also a technical measure that must be taken by all mechanical equipment at present. It has become a conventional technology in the professional field, so there is no need to describe the electromechanical digital control of the equipment in the present invention. The only thing that needs to be stated is that the electrical characteristics of the xenon excimer light source are very good, and the electrical control of "on and off in seconds" can be realized, and there is no preheating time and it will not affect the service life of the xenon excimer lamp. As described in the background, when the xenon excimer lamp is turned on, it can excite the surrounding oxygen molecules and water molecules to form active substances with disinfection effects (expressed in this document as xenon excimer active oxygen clusters), so the "on and off in seconds" electrical characteristics of the xenon excimer means that the use of a xenon excimer light source can accurately prepare the dose of the released xenon excimer active oxygen clusters. This will be a very valuable technical parameter. At present, the safety evaluation of xenon excimer active oxygen clusters is controlled in accordance with the national safety evaluation standards for ozone. The current safety concentration standard for ozone is 0.1mg / m 3 When the safe concentration of ozone reaches 0.16mg / m 3 When the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine humidifies and disinfects the indoor environment, it also takes into account the purpose of surface disinfection. When the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine humidifies and disinfects the indoor air, the concentration of the released xenon excimer active oxygen clusters shall not exceed 0.1mg / m 3 The safety limit should not exceed 0.16 mg / m within 8 hours. 3 safety limit. When it is necessary to disinfect the surface of an object, it is hoped that the instantaneous concentration of the xenon excimer active oxygen clusters released by the equipment in a short period of time is as high as possible, because the disinfection effect is expressed by the CT value, where C represents the concentration of the disinfecting factor and T represents the time. Therefore, the higher the value of C, the shorter the disinfection time required. Obviously, when disinfecting the surface of an object, the shorter the time is hoped to be. For example, when you put your hands into the ultrasonic atomized water mist sprayed by the equipment to disinfect the surface of your hands, it is obviously hoped that the shorter the time is, the better. Existing experimental data show that when the ozone concentration in the water reaches about 1ppm, the time required to kill 100% of various harmful microorganisms such as Escherichia coli, Staphylococcus aureus, and viruses is between 5-10 seconds. Based on this information, it is suggested that the opening time of the xenon excimer light source of the xenon excimer ultrasonic atomization disinfector should generally be based on the indoor ozone concentration of 0.1mg / m 3 -0.16mg / m 3When it is necessary to control the switching between the two modes, and when it is necessary to disinfect the surface of an object, it is hoped that all xenon excimer light sources will be turned on for a short period of time, so as to form an instantaneous high concentration of xenon excimer reactive oxygen clusters in the ultrasonic atomization water vapor mist in a short period of time, quickly complete the disinfection of the surface of the object, and then quickly return to the release state of low concentration of xenon excimer reactive oxygen clusters. The best control method to achieve this rapid conversion is a one-touch button or voice recognition control. In addition, the equipment should be equipped with an ozone concentration detection sensor. When the ozone concentration around the xenon excimer light source reactive oxygen cluster ultrasonic atomization disinfector exceeds 0.1mg / m 3 -0.16mg / m 3 When the xenon excimer light source is turned off, an alarm is sounded.

[0031] from Figure 5 It can be seen from the design that the nozzle of the ultrasonic atomization steam of the xenon excimer light source active oxygen cluster ultrasonic atomization water tank upper disinfection machine is designed to be in the shape of a bent neck. The advantage of this design is that the ultrasonic atomization sprays in one direction. At this time, if surface disinfection is required (such as hand washing disinfection), people can stand on the back of the bent neck and extend their hands into the steam atomization area for disinfection without being eroded by high concentrations of xenon excimer active oxygen clusters.

[0032] On the same day, the applicant submitted an invention patent application for the basic design method of a xenon excimer light source active oxygen cluster ultrasonic atomization disinfection machine and a utility patent application for a xenon excimer light source active oxygen cluster ultrasonic atomization water tank lower disinfection machine.
