Description

Technical Field

[0001] The invention relates to the technical field of spray cooling, and in particular to a high-pressure micro-mist device. Background Art

[0002] In today's rapidly developing era, data centers, as key hubs for information storage and processing, continue to grow in size and number. At the same time, the development and utilization of underground space is becoming increasingly widespread, and special facilities such as cave-type data centers are constantly emerging. These places generate a lot of heat during operation due to their dense equipment and heavy computing loads, and heat dissipation and cooling have become one of the core issues to ensure their normal operation.

[0003] The cooling method of data centers mainly relies on air conditioning and refrigeration systems. Such systems usually use mechanical compression refrigeration cycles to absorb and release heat through the phase change of the refrigerant to achieve the purpose of regulating the indoor temperature. However, air conditioning and refrigeration consume extremely high energy. Especially in the high temperature period in summer or when the equipment is under high load, in order to maintain a suitable temperature, the refrigeration system needs to continue to operate at high power, making the electricity cost account for too large a proportion of the total operating cost, bringing a heavy economic burden to the enterprise. Taking a medium-sized data center as an example, the power consumption of air conditioning in summer can account for 40%-60% of the total power consumption, which not only causes a large waste of energy, but also runs counter to the current green, environmental protection, energy conservation and emission reduction concepts advocated.

[0004] For some special underground space environments, such as cave-type data centers, the ventilation conditions are relatively complex. The outside air may carry pollutants such as dust and impurities when it is introduced. The traditional air-conditioning system lacks an effective pretreatment mechanism for this. Long-term operation can easily cause dust accumulation in internal equipment, increasing the risk of failure.

[0005] At the same time, although the existing spray cooling technology has been applied in some fields, it still has many defects when applied to data centers and similar underground spaces. The structural design of some spray devices is unreasonable, and the distribution of spray nozzles is uneven, resulting in limited and uneven spray coverage, which cannot fully and effectively cool the incoming air. Moreover, the bracket structure used by the spray device is usually relatively weak. In the special airflow environment of the underground space, especially when facing the wind, it is easy to shake or even be damaged, which not only affects the spray effect, but also may endanger the safety of surrounding equipment. In addition, many spray devices do not fully consider the impact of water quality on the nozzle and the entire system, and are not equipped with a complete water purification and filtration link. Impurities in the water can easily clog the nozzle and reduce the spray efficiency. Frequent nozzle replacement and maintenance further increase operating costs.

[0006] In summary, existing cooling technologies are unable to meet the urgent needs for efficient, energy-saving, and stable cooling of data centers and underground spaces, and a completely new solution is needed. Summary of the invention

[0007] In order to solve the above problems, especially to address the deficiencies in the prior art, the present invention provides a high-pressure fine mist device that can solve the above problems.

[0008] To achieve the above purpose, the present invention adopts the following technical means:

[0009] A high-pressure micro-mist device, comprising a controller, a raw water tank, a physical filter, a precision filter, an RO reverse osmosis pure water device, a pure water tank, a high-pressure micro-mist machine, and a high-pressure micro-mist spray unit, wherein the raw water tank is connected to the physical filter through a raw water pump, the physical filter is connected to the precision filter, the precision filter is connected to the RO reverse osmosis pure water device through a high-pressure pump, the RO reverse osmosis pure water device is connected to the pure water tank, the pure water tank is connected to the high-pressure micro-mist machine through a pure water pump, and the high-pressure micro-mist machine is connected to the high-pressure micro-mist spray unit;

[0010] The high-pressure micro-mist spray unit comprises a plurality of evenly distributed support rods, the support rods are connected to a plurality of evenly distributed triangular brackets, the tops of the triangular brackets located on the same layer are connected to water supply pipes, the water supply pipes are connected to a plurality of atomizing nozzles, and the water supply pipes are connected to the high-pressure micro-mist machine through an electric water supply valve;

[0011] The raw water pump, the high-pressure pump, the pure water pump, the high-pressure micro-mist machine, and the electric water supply valve are electrically connected to the controller respectively.

[0012] A further solution of the present invention is that the controller is a PLC controller.

[0013] A further solution of the present invention is that the physical filter comprises a filter housing, a quartz sand filter, an activated carbon filter and a resin filter are connected in the filter housing, and the quartz sand filter is connected to the resin filter through the activated carbon filter.

[0014] A further solution of the present invention is that the high-pressure micro-mist machine includes a micro-mist machine housing, a spare water tank is connected to the micro-mist machine housing, the spare water tank is connected to the pure water pump through a water inlet solenoid valve, the spare water tank is connected to the electric water supply valve through a water pump motor, and the water inlet solenoid valve and the water pump motor are electrically connected to the controller respectively.

[0015] A further solution of the present invention is that a liquid level sensor is connected to the spare water tank, and the liquid level sensor is electrically connected to the controller.

[0016] A further solution of the present invention is that the standby water tank is connected to a drainage pipe that runs through the micro-mist machine housing.

[0017] A further solution of the present invention is that the triangular bracket and the support rod are both made of stainless steel.

[0018] A further solution of the present invention is that the atomizing nozzle is a V-shaped double-headed atomizing nozzle.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention can save energy and reduce air temperature. It is used to reduce the temperature of incoming air in underground spaces such as data centers, and can effectively reduce the temperature of high-temperature air entering from the outdoors in summer. The high-pressure mist machine converts pure water into fine water mist, which evaporates and absorbs heat, which can significantly reduce the inlet air temperature and reduce the load of subsequent cooling equipment, thereby saving a lot of energy costs. Compared with traditional air conditioning refrigeration and cooling methods, energy consumption is greatly reduced.

[0021] 2. The structure of the present invention is strong and durable. The triangular bracket structure of the high-pressure micro-mist spray unit is simple and utilizes the stability of the triangle. It is strong and durable as a whole and does not shake when facing the wind. The stainless steel pipes further enhance the wind resistance of the device, ensuring that in the long-term operation, even in the face of complex ventilation airflow in the underground space, the device can still operate stably and reliably, reducing maintenance costs.

[0022] 3. The spray uniformity of the present invention is good. The design of multiple groups of evenly distributed support rods, triangular brackets, water supply pipes and atomizing nozzles enables the water mist to be evenly sprayed on the air inlet surface, ensuring the consistency of the cooling effect, avoiding the situation of local over-high or over-low temperature, and providing a stable and suitable operating environment for electronic equipment in the data center.

[0023] 4. The water quality of the present invention is guaranteed. Through multi-stage filtration of physical filters, precision filters and RO reverse osmosis pure water devices, the water entering the high-pressure micro-fog machine is ensured to be pure water with high purity, which effectively prevents nozzle clogging and prolongs the service life of the nozzle. At the same time, it ensures the quality of the spray and improves the cooling and humidification effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 to Figure 2 As shown, a high-pressure micro-mist device includes a controller 1, a raw water tank 2, a physical filter 4, a precision filter 5, an RO reverse osmosis pure water device 7, a pure water tank 8, a high-pressure micro-mist machine 10, and a high-pressure micro-mist spray unit. The raw water tank 2 is connected to the physical filter 4 through a raw water pump 3, the physical filter 4 is connected to the precision filter 5, the precision filter 5 is connected to the RO reverse osmosis pure water device 7 through a high-pressure pump 6, the RO reverse osmosis pure water device 7 is connected to the pure water tank 8, the pure water tank 8 is connected to the high-pressure micro-mist machine 10 through a pure water pump 9, and the high-pressure micro-mist machine 10 is connected to the high-pressure micro-mist spray unit;

[0034] The high-pressure micro-mist spray unit includes a plurality of evenly distributed support rods 13, to which a plurality of evenly distributed triangular brackets 12 are connected, and a water supply pipe 14 is connected to the top of the triangular brackets 12 on the same layer, to which a plurality of atomizing nozzles 15 are connected, and the water supply pipe 14 is connected to the high-pressure micro-mist machine 10 through an electric water supply valve 11;

[0035] The raw water pump 3 , the high-pressure pump 6 , the pure water pump 9 , the high-pressure mist machine 10 , and the electric water supply valve 11 are electrically connected to the controller 1 , respectively.

[0036] Working principle:

[0037] 1. Water source transportation and pretreatment stage

[0038] The raw water tank 2 is used as a water source storage place to store the raw water to be treated. When the system is started, the raw water pump 3 starts to work, pumping out the water in the raw water tank 2 and transporting it to the physical filter 4. After fine filtration by the physical filter 4, the purity of the water is greatly improved, preliminarily meeting the relatively strict requirements of the subsequent high-pressure micro-mist system for the inlet water quality, and then the preliminarily purified water flows into the precision filter 5.

[0039] 2. Deep filtration and pure water preparation stage

[0040] The precision filter 5, with its high-precision filter medium, can further filter out tiny particle impurities remaining in the water. Even extremely fine impurities that may affect the operation of subsequent equipment are difficult to escape, ensuring that the water entering the RO reverse osmosis pure water device 7 reaches a higher purity standard, laying a solid foundation for the stable and efficient operation of the RO reverse osmosis pure water device.

[0041] Next, the high-pressure pump 6 pressurizes the water after precision filtration to make it have sufficient pressure, and then delivers it to the RO reverse osmosis pure water device 7. The RO reverse osmosis pure water device operates based on the characteristics of the unique material of the semipermeable membrane. Under pressure, only water molecules can pass through the semipermeable membrane, while almost all soluble solids, microorganisms, colloids and other impurities are intercepted, thereby producing nearly pure water, which is delivered to the pure water tank 8 for storage as a high-quality water source for subsequent spray cooling.

[0042] 3. Spray execution stage

[0043] When spray cooling operation is required, the controller 1 starts to play its core control role, starts the pure water pump 9, extracts the pure water in the pure water tank 8 and delivers it to the high-pressure micro-mist machine 10. The high-pressure micro-mist machine 10 makes the delivered pure water have high-pressure potential energy, and then delivers it to the water supply pipe 14 through the electric water supply valve 11. The multiple groups of atomizing nozzles 15 connected to the water supply pipe 14 are the key links to achieve water mist generation. When the high-pressure water passes through the nozzle, the special internal structure design of the nozzle is used to break the high-pressure water flow and atomize it into tiny particles, and fine water mist is sprayed out.

[0044] 4. Spray structure stability guarantee stage

[0045] In terms of the spray unit structure, multiple groups of evenly distributed support rods 13 build a stable support frame for the entire spray structure. The triangular bracket 12 connected to it is based on the principle of triangle stability, giving the overall structure of the spray unit a sturdy and durable characteristic, so that it will not shake easily in an outdoor windy environment. In addition, the triangular bracket 12 and the support rod 13 are both made of stainless steel, and are matched with a water supply pipeline of the same material, so that when the entire device is facing the wind, it can effectively reduce the shaking caused by the wind, reduce the windward resistance, and ensure that the water mist can be accurately and stably sprayed in the direction of the wind inlet, optimize the temperature of the wind inlet surface to the greatest extent, and achieve an efficient and energy-saving outdoor wind inlet cooling effect.

[0046] 5. System Intelligent Control Stage

[0047] During the entire operation process, the operation status of key components such as the raw water pump 3, high-pressure pump 6, pure water pump 9, high-pressure micro-fog machine 10, and electric water supply valve 11 are precisely controlled by the controller 1 according to the preset program or the environmental parameters collected in real time. For example, in a hot and dry environment, the controller 1 can instruct to increase the spray water volume and water pressure, quickly reduce the ambient temperature and increase the air humidity; and in a period of relatively suitable temperature and high humidity, the controller 1 can appropriately reduce the operating power of each component, reduce energy consumption, and ensure that the device flexibly adjusts the spray water volume and water pressure according to actual needs to achieve the best cooling and energy-saving effect.

[0048] Example 2

[0049] like Figure 1 to Figure 2 As shown, a high-pressure micro-mist device includes a controller 1, a raw water tank 2, a physical filter 4, a precision filter 5, an RO reverse osmosis pure water device 7, a pure water tank 8, a high-pressure micro-mist machine 10, and a high-pressure micro-mist spray unit. The raw water tank 2 is connected to the physical filter 4 through a raw water pump 3, the physical filter 4 is connected to the precision filter 5, the precision filter 5 is connected to the RO reverse osmosis pure water device 7 through a high-pressure pump 6, the RO reverse osmosis pure water device 7 is connected to the pure water tank 8, the pure water tank 8 is connected to the high-pressure micro-mist machine 10 through a pure water pump 9, and the high-pressure micro-mist machine 10 is connected to the high-pressure micro-mist spray unit;

[0050] The high-pressure micro-mist spray unit includes a plurality of evenly distributed support rods 13, to which a plurality of evenly distributed triangular brackets 12 are connected, and a water supply pipe 14 is connected to the top of the triangular brackets 12 on the same layer, to which a plurality of atomizing nozzles 15 are connected, and the water supply pipe 14 is connected to the high-pressure micro-mist machine 10 through an electric water supply valve 11;

[0051] The raw water pump 3 , the high-pressure pump 6 , the pure water pump 9 , the high-pressure mist machine 10 , and the electric water supply valve 11 are electrically connected to the controller 1 , respectively.

[0052] Controller 1 is a PLC controller.

[0053] The advantages of the above settings are:

[0054] Precise control function

[0055] The PLC controller can accurately control the time and operation sequence of the raw water pump 3, the high-pressure pump 6, the pure water pump 9, the high-pressure micro-fog machine 10 and the electric water supply valve 11. For example, it can accurately set the start time, running time and stop time of each water pump. During the spraying process, according to different ambient temperature and humidity requirements, the opening of the electric water supply valve 11 can be accurately adjusted to control the water supply so that the amount of water mist sprayed by the atomizing nozzle 15 can achieve the best cooling effect.

[0056] The PLC controller can also accurately adjust the working pressure of the high-pressure mist machine 10. Accurate control of the water pressure is achieved to ensure that the atomization effect of the water mist is uniform and stable, which is crucial to the quality and efficiency of spray cooling.

[0057] High degree of automation

[0058] The PLC controller can automatically operate the entire high-pressure micro-mist device according to the preset program. For example, the timed spray function can be set to automatically start spray cooling during the high temperature period of the day and automatically stop during the lower temperature period. This automated operation reduces the need for manual intervention and improves the convenience of the device.

[0059] It can also be connected to environmental sensors to achieve closed-loop control. When the ambient temperature rises or the humidity drops to a certain level, the PLC controller can automatically start the spray device and adjust the spray parameters to keep the ambient temperature and humidity within the set comfortable range without manual monitoring and adjustment.

[0060] High reliability and stability

[0061] PLC controllers have strong anti-interference capabilities. In industrial or outdoor environments, there may be various adverse factors such as electromagnetic interference and power fluctuations. PLC controllers can effectively resist these interferences, ensuring the normal operation of their internal programs and stable control of various devices. For example, in places with strong electromagnetic interference such as factory workshops, PLC controllers can ensure the stable operation of high-pressure micro-mist devices, and will not cause misoperation or equipment failure due to external interference.

[0062] Its hardware structure is solid and can adapt to harsh working environments. Whether it is a hot, humid or dusty environment, the PLC controller can work normally, which is very important for high-pressure micro-fog devices used outdoors for a long time. Moreover, the software programming of the PLC controller has good fault tolerance. Even if some small program errors or equipment abnormalities occur, the pre-set error correction mechanism or alarm function can ensure the safe operation of the device.

[0063] Flexible programming and scalability

[0064] The programming of the PLC controller is relatively simple and flexible. The control program can be easily modified according to different application scenarios and user needs. For example, if you need to change the spray mode, such as changing from continuous spray to intermittent spray, or adjusting the spray pressure range, you only need to modify the PLC controller program accordingly.

[0065] It also has good scalability. If new functions need to be added, such as connecting to a remote monitoring system to achieve remote control and data transmission, or adding more sensors to obtain more comprehensive environmental information, the PLC controller can easily perform hardware expansion and software updates to adapt to these new requirements.

[0066] like Figure 3 As shown, the physical filter 4 includes a filter housing 401 , in which a quartz sand filter 402 , an activated carbon filter 403 , and a resin filter 404 are connected. The quartz sand filter 402 is connected to the resin filter 404 through the activated carbon filter 403 .

[0067] The advantages of the above settings are:

[0068] Multi-layer filtration to improve water purification effect

[0069] Initial filtration of the quartz sand filter 402: The quartz sand filter uses the gaps between the quartz sand particles to filter larger particle impurities in the raw water, such as silt, suspended matter, etc. If these impurities are not removed, they may clog subsequent filters or nozzles, affecting the normal operation of the device. For example, in a water source containing a lot of silt, the quartz sand filter can effectively intercept the silt particles and prevent them from entering the more refined filtration link.

[0070] Deep purification of activated carbon filter 403: After preliminary filtration by the quartz sand filter, the water enters the activated carbon filter. Activated carbon has a rich porous structure, which enables it to adsorb odor molecules, organic matter and some residual chlorine in the water. The odor in the water may come from the water source itself or some chemicals produced during the storage process. The adsorption of activated carbon can effectively improve the smell and taste of the water. At the same time, activated carbon can also adsorb residual chlorine in the water, reducing the corrosion of chlorine to subsequent equipment, and avoiding the adverse effects of residual chlorine in the water on the spray environment. For example, in some places that are sensitive to odors, activated carbon filters can improve the purity of water quality.

[0071] Water quality optimization of resin filter 404: Resin filter is mainly used to remove calcium, magnesium and other ions in water, that is, to reduce the hardness of water. Calcium and magnesium ions in hard water exist in the form of compounds in water. When water flows in equipment and pipes, these ions may form scale. In high-pressure micro-mist devices, the formation of scale will reduce the heat exchange efficiency of the equipment, block pipes and nozzles, etc. After removing these ions through the resin filter, it can effectively prevent subsequent equipment scaling, extend the service life of the equipment, and ensure the stable operation of the entire device.

[0072] The filters are connected in sequence to give full play to the advantages of each filter

[0073] The quartz sand filter 402 first filters to remove large particles of impurities, reducing the burden on the subsequent activated carbon filter 403 and resin filter 404. Without this step, large particles of impurities may quickly clog the activated carbon and resin filters, reducing their service life and filtering efficiency.

[0074] The activated carbon filter 403 is in the middle. After removing organic matter and odor impurities in the water, it delivers relatively clean water to the resin filter 404. This can avoid the interference of organic matter and other impurities on the resin filter, ensuring that the resin filter can more effectively remove hardness ions in the water. In addition, the chemical properties of the water after the activated carbon filter are more stable, which is conducive to the ion exchange process of the resin filter, thereby improving the comprehensive filtering effect of the entire physical filter.

[0075] Integrated in a filter housing 401, saving space and easy maintenance

[0076] Space saving: The quartz sand filter 402, the activated carbon filter 403 and the resin filter 404 are integrated into a filter housing 401, which greatly saves the space occupied by the device compared to using multiple separate filters. This is very beneficial for application scenarios with limited space, and can make the layout of the entire high-pressure micro-mist device more compact and reasonable.

[0077] Easy maintenance: All filters are concentrated in one housing, which is convenient for operators to perform maintenance work such as inspection, repair and replacement of filter elements. Maintenance personnel can open the filter housing 401 to conveniently check the working status of each filter, such as whether the quartz sand needs to be cleaned or replaced, whether the activated carbon is saturated, whether the resin is invalid, etc. Moreover, when it is necessary to replace the filter element or perform maintenance, all operations are performed in a relatively concentrated area, which improves the efficiency of maintenance work.

[0078] The triangular bracket 12 and the support rod 13 are both made of stainless steel.

[0079] The advantages of the above settings are:

[0080] Corrosion resistance

[0081] In outdoor environments, the high-pressure micro-mist device is often exposed to various weather conditions, such as rain, dew, etc. If the tripod bracket 12 and the support rod 13 are made of ordinary metal materials, they are easily corroded and rusted. Stainless steel has excellent corrosion resistance and can resist the erosion of rain, humid air, and chemicals that may be contained in water, such as dissolved salts. For example, when the device is used at the seaside or in areas with severe industrial pollution, the tripod bracket 12 and the support rod 13 made of stainless steel can maintain structural integrity for a long time, and the stability and service life of the device will not be affected by corrosion.

[0082] High strength and stability

[0083] Stainless steel has high strength and can bear the weight of the atomizing nozzle 15, the water supply pipe 14 and the water mist. During the spraying process, the triangular bracket 12 and the support rod 13 serve as supporting structures and need to ensure the stability of the entire spray unit. Especially when the device is working outdoors in a windy environment, strong winds may exert a large force on the spray unit. The stainless steel structure can effectively resist these external forces and prevent the device from shaking or tipping over. The triangular structure bracket itself has good stability, coupled with the high strength characteristics of stainless steel, it can better fix the water supply pipe 14 and the atomizing nozzle 15, so that the water mist sprayed by the nozzle can be accurately distributed in the target area, ensuring the spray cooling effect.

[0084] Easy to clean and maintain

[0085] The surface of stainless steel is relatively smooth and not easily contaminated by dust, dirt and other impurities. Even if there are some stains on the surface during use, it is relatively easy to clean. When regularly maintaining the high-pressure micro-mist device, it is relatively simple to clean the tripod bracket 12 and the support rod 13. For example, most of the stains on the surface can be removed by gently wiping with a damp cloth, without the need for special cleaning tools or complicated cleaning processes, which helps to reduce maintenance costs and time.

[0086] Good temperature adaptability

[0087] Stainless steel can maintain good performance under different temperature environments. Whether in hot summer or cold winter, the stainless steel triangular bracket 12 and support rod 13 will not produce obvious physical property changes due to temperature changes. In the high temperature of summer, the structure will not be deformed due to thermal expansion, affecting the accuracy of the spray unit; in the cold winter, there will be no embrittlement and other problems, ensuring that the device can operate normally under various climatic conditions.

[0088] like Figure 5 As shown, the atomizing nozzle 15 is a V-shaped double-headed atomizing nozzle.

[0089] The advantages of the above settings are:

[0090] Good atomization effect

[0091] Bidirectional spray characteristics: The V-shaped double-head atomizing nozzle has two spray outlets and can spray in two directions at the same time. Compared with a single-head nozzle, it can expand the spray coverage and make the water mist more evenly distributed in the space. For example, when used for outdoor air intake cooling, the double-head design allows the water mist to fully contact the air in a wider area, quickly reducing the temperature of the passing air, thereby effectively improving the cooling effect.

[0092] Fine atomization capability: This nozzle can atomize water into tiny particles. Tiny water mist particles have a larger surface area, and when in contact with the air, the heat exchange efficiency is higher. In addition, fine particles of water mist are suspended in the air for a relatively long time, which can more fully absorb the heat in the air and make the surrounding temperature drop more significantly. At the same time, fine particles of water mist also help to increase air humidity and improve the local microclimate.

[0093] Improve work efficiency

[0094] Increased spray volume: The dual-head design increases the spray volume per unit time. In scenarios where rapid cooling is required, such as factory workshops and outdoor venues, a larger spray volume can reduce the ambient temperature more quickly and meet actual usage needs. For example, when used in large sports venues, it can quickly create a relatively cool environment for spectators and athletes.

[0095] Balanced spray distribution: The V-shaped double-head atomizing nozzle can spray droplets evenly in two directions, avoiding the problem of excessive local temperature differences caused by uneven spraying. This helps to achieve a more consistent cooling effect in the entire spraying area, improves work efficiency overall, and reduces the need for additional operations such as frequent adjustment of nozzle positions due to uneven spraying.

[0096] Good structural stability

[0097] V-shaped structure advantage: The V-shaped structure of the nozzle itself has good stability. When high-pressure water passes through the nozzle, this structure can better withstand the internal water pressure and reduce the risk of damage to the nozzle due to pressure shock. Compared with some nozzles with simple structures, the V-shaped double-head atomizing nozzle works more reliably in a long-term high-pressure environment, reducing the frequency of repairing and replacing the nozzle, thereby reducing maintenance costs.

[0098] Highly adaptable

[0099] Adaptation to different application scenarios: This nozzle can adjust the spray angle according to actual needs. Whether it is horizontal spray for large-area cooling, or slightly adjusted upward or downward for special space layout or target area cooling, the V-shaped double-head atomizing nozzle can adapt well. It can also be adapted to different water supply pipelines and spray systems, and flexibly integrated into the design of various high-pressure micro-fog devices to meet the personalized needs of different users.

[0101] like Figure 1 to Figure 2 As shown, a high-pressure micro-mist device includes a controller 1, a raw water tank 2, a physical filter 4, a precision filter 5, an RO reverse osmosis pure water device 7, a pure water tank 8, a high-pressure micro-mist machine 10, and a high-pressure micro-mist spray unit.

[0103] The raw water pump 3 , the high-pressure pump 6 , the pure water pump 9 , the high-pressure mist machine 10 , and the electric water supply valve 11 are electrically connected to the controller 1 , respectively.

[0104] like Figure 4 As shown, the high-pressure micro-mist machine 10 includes a micro-mist machine housing 1001, and a spare water tank 1004 is connected to the micro-mist machine housing 1001. The spare water tank 1004 is connected to the pure water pump 9 through a water inlet solenoid valve 1002. The spare water tank 1004 is connected to the electric water supply valve 11 through a water pump motor 1005. The water inlet solenoid valve 1002 and the water pump motor 1005 are electrically connected to the controller 1 respectively.

[0105] The advantages of the above settings are:

[0106] Water source reserve and stable water supply function

[0107] The buffering effect of the spare water tank: The spare water tank 1004 plays a buffering role in the whole system. In the case of a short-term fluctuation or interruption in the water supply of the pure water pump 9, such as a pure water pump failure or a temporary blockage of the water supply pipeline, the reserve water in the spare water tank 1004 can continue to provide water for the spray process. This ensures that the high-pressure micro-mist device will not stop working due to a momentary water supply problem, maintains the continuity of the spray cooling, and ensures the temperature stability of the use site.

[0108] Stable water supply guarantee: The water inlet of the standby water tank 1004 is controlled by the water inlet solenoid valve 1002, so as to realize accurate control of the water level of the water tank. When the water level of the water tank drops, the controller 1 can timely open the water inlet solenoid valve 1002 according to the feedback signal of the liquid level sensor or the preset water level control program, so as to allow the pure water pump 9 to replenish the water source to the standby water tank 1004. At the same time, the water pump motor 1005 can stably draw water from the standby water tank 1004 and supply water to the spray unit through the electric water supply valve 11, so as to ensure a stable water supply to the atomizing nozzle 15, thereby ensuring the quality and effect of the spray.

[0109] Ease of implementation of intelligent control

[0110] Collaboration with the controller: The water inlet solenoid valve 1002 and the water pump motor 1005 are electrically connected to the controller 1 respectively, which enables the entire water supply process to be intelligently controlled. The controller 1 can accurately control the opening and closing time of the water inlet solenoid valve 1002 and the speed of the water pump motor 1005 according to the preset program, environmental parameters such as temperature, humidity or manual instructions of the user. For example, when the spray volume needs to be increased in a high temperature environment, the controller 1 can control the water inlet solenoid valve 1002 to extend the opening time to quickly replenish the water volume of the spare water tank 1004, and at the same time increase the speed of the water pump motor 1005 to increase the water supply pressure and flow, thereby achieving efficient spray cooling.

[0111] Integrated design space advantage and protection function

[0112] Efficient space utilization: The spare water tank 1004, the water inlet solenoid valve 1002 and the water pump motor 1005 are integrated inside the micro mist housing 1001, making full use of the space. This compact design reduces the footprint of the entire high-pressure micro mist device, making the structure of the device more compact, and is convenient for installation and layout in different venues such as workshops with limited space and corners of outdoor activity venues.

[0113] Component protection: The mist housing 1001 provides physical protection for the internal spare water tank 1004, the water inlet solenoid valve 1002 and the water pump motor 1005. It can prevent external dust, debris, moisture, etc. from entering the internal components, reducing the possibility of component damage due to external factors. At the same time, the housing can also play a certain role in sound insulation and heat insulation, reducing the impact of noise generated by the operation of internal components on the surrounding environment, and reducing the interference of external temperature changes on the internal water supply system.

[0114] A liquid level sensor 1003 is connected to the spare water tank 1004 , and the liquid level sensor 1003 is electrically connected to the controller 1 .

[0115] The advantages of the above settings are:

[0116] Accurate water level monitoring and control

[0117] Real-time feedback of water level information: The liquid level sensor 1003 can monitor the water level in the standby water tank 1004 in real time, and convert the water level signal into an electrical signal and send it to the controller 1. The controller 1 accurately understands the water level status in the water tank based on the received signal. For example, when the water level drops to a certain level, the controller 1 can react immediately to avoid the idling of the water pump motor 1005 due to the low water level, thereby protecting the equipment and ensuring the continuity of water supply.

[0118] Precise water replenishment control: Based on the feedback from the liquid level sensor 1003, the controller 1 can accurately control the opening and closing of the water inlet solenoid valve 1002 to achieve precise water replenishment of the spare water tank 1004. When the water level is lower than the set lower limit, the controller 1 opens the water inlet solenoid valve 1002 to allow the pure water pump 9 to inject water into the spare water tank 1004; when the water level reaches the set upper limit, the controller 1 closes the water inlet solenoid valve 1002 to stop injecting water. This precise control can effectively prevent the water tank from overflowing or lacking water, and ensure that there is always an appropriate amount of water in the water tank.

[0119] Improve the reliability and stability of the device

[0120] Prevent equipment damage: Through the monitoring of the liquid level sensor 1003, it is possible to avoid failures such as dry burning of the water pump motor 1005 due to lack of water. Dry burning may damage the water pump motor and shorten the service life of the equipment. With the protection of the liquid level sensor 1003, once the water level is too low, the controller 1 can stop the operation of the water pump motor 1005 in time until the water level returns to normal, thereby greatly improving the reliability of the equipment.

[0121] Ensure the continuity of the spray process: During the spray process, a stable water supply is essential. The cooperation between the liquid level sensor 1003 and the controller 1 ensures that there is enough water in the spare water tank 1004 for spraying. Even if the pure water pump 9 fails temporarily or the water supply pressure fluctuates, as long as there is a certain amount of reserve water in the spare water tank 1004, the spray process can continue, thereby ensuring the stability of the operation of the entire high-pressure micro-mist device and enabling the spray cooling work to be carried out continuously and effectively.

[0122] Optimize energy efficiency

[0123] Avoid unnecessary energy consumption: When the liquid level sensor 1003 detects that the water level of the standby water tank 1004 is full, the controller 1 will close the water inlet solenoid valve 1002 to prevent the pure water pump 9 from continuing to inject water, thereby preventing the waste of electricity due to excessive water injection. At the same time, by accurately controlling the water level in the water tank, it can also ensure that the water pump motor 1005 works under appropriate water level conditions, avoiding the reduction of the working efficiency of the water pump motor 1005 due to too low or too high water level, thereby optimizing the energy utilization efficiency of the entire device.

[0124] Key links in intelligent automation operation

[0125] Realize intelligent control logic: The liquid level sensor 1003 is an important component for realizing the intelligent and automatic operation of the high-pressure micro-mist device. It works together with the controller 1 and other components to form a complete intelligent control system. For example, in different spraying scenarios, the controller 1 can flexibly adjust the working state of the water inlet solenoid valve 1002 and the water pump motor 1005 according to the feedback of the liquid level sensor 1003 and the preset spraying strategy, and realize intelligent spraying according to actual needs, such as automatically adjusting the spray volume and spray time according to the ambient temperature and humidity.

[0126] The standby water tank 1004 is connected to a drainage pipe 1006 that passes through the micro mist machine housing 1001 .

[0127] The advantages of the above settings are:

[0128] Drainage convenience and maintainability

[0129] Convenient drainage operation: The setting of the drain pipe 1006 allows the water in the spare water tank 1004 to be easily drained. For example, when the spare water tank 1004 needs to be cleaned or repaired, or the device is not used for a long time and needs to be emptied, the water in the water tank can be quickly and completely drained through the drain pipe 1006. This operation is simple and easy, and does not require complicated tools or additional equipment. You only need to open the drain valve if there is one or connect the drain pipe.

[0130] Convenient for maintenance: When maintaining the high-pressure mist device, especially when it involves the inspection, repair or replacement of the internal components of the spare water tank 1004, emptying the water tank is an essential step. The drain pipe 1006 can ensure that the water in the water tank can be drained smoothly, providing a dry and safe working environment for maintenance personnel, making it convenient for them to enter the water tank to perform various maintenance operations, such as cleaning scale, checking sensors, repairing pipes, etc.

[0131] Prevent water quality deterioration in the water tank

[0132] Preventing water from deteriorating: If the standby water tank 1004 does not have a drainage device, long-term water accumulation may cause water quality to deteriorate. Microorganisms such as bacteria and algae may grow in the water, which may pollute the water tank and the entire water supply system. The drain pipe 1006 can regularly drain the old water in the water tank and replace it with new water, thereby ensuring good water quality in the standby water tank 1004, reducing the possibility of microbial growth, extending the service life of the equipment, and ensuring the quality of the spray water.

[0133] Drainage function for emergency situations

[0134] Handling abnormal water inflow: In some special cases, such as when the water inlet solenoid valve 1002 fails and causes excessive water inflow into the water tank, or when the water tank is contaminated by the outside world, the drain pipe 1006 can be used as an emergency drainage channel to quickly drain excess or contaminated water, thereby avoiding damage to the equipment caused by overflow of the water tank or preventing contaminated water from entering the spray system, thereby ensuring the normal operation of the entire high-pressure micro-mist device.

[0135] Flexible system integration and adaptability

[0136] Connected to external drainage system: The drainage pipe 1006 runs through the micro mist housing 1001, which is convenient for connecting to the external drainage system. This connection method enables the entire device to better adapt to different installation environments, reasonably guide the drainage to the designated drainage area, and avoid the adverse effects of drainage on the surrounding environment, such as water accumulation, slippery ground, etc.

[0137] The examples given in the present invention are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
