[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

Of course, they are only examples and the purpose is not to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples in the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0037] For the purpose of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings.

[0038] Please refer to Figures 1 to 7 The present application provides an atomization device, a cold storage refrigeration system and a control method of the atomization device to solve the problem that impurities accumulated during long-term use of the atomization device affect the atomization effect and cause damage to the device.

[0039] In a first aspect, as Figure 1 , Figure 2 and Figure 3As shown, the present application provides an atomization device 10, which includes a water tank 11, an atomizer 12, a first spray head 13 and a second spray head 14. The water tank 11 is provided with an air outlet 113 and a water outlet 114, and the atomizer 12 is arranged in the water tank 11 for atomizing the liquid in the water tank 11. The first spray head 13 is arranged in the water tank 11 for spraying the washing liquid towards the atomizer 12. The second spray head 14 is arranged in the water tank 11 for spraying the washing liquid towards the bottom of the water tank 11.

[0040] The atomization device 10 includes a water tank 11, which is configured as a container for containing the liquid to be atomized. In order to realize the air flow and liquid discharge, the water tank 11 is provided with an air outlet 113 and a water outlet 114. The air outlet 113 can be arranged as an opening on the upper part of the water tank 11, allowing the water mist particles generated by the atomizer 12 in the water tank 11 to be discharged through the air outlet 113, thereby achieving the humidification effect. The water outlet 114 can be arranged as an opening on the bottom of the water tank 11 for discharging the liquid in the water tank 11 when needed. For example, the water outlet 114 can be a simple hole that realizes water discharge by gravity.

[0041] Inside the water tank 11, an atomizer 12 is arranged. The atomizer 12 is used to convert the liquid in the water tank 11 into mist to achieve the humidification function. The atomizer 12 can be fixed on the bottom or side wall of the water tank 11, and part of it is immersed in the liquid during operation. For example, the atomizer 12 can be a vibrating element that generates mist on the surface of the liquid through high-frequency vibration.

[0042] In order to clean the atomizer 12, the device further includes one or more first spray heads 13. The first spray head 13 is arranged inside the water tank 11, and the spraying direction is arranged towards the atomizer 12. When the atomizer 12 needs to be cleaned, the washing liquid is sprayed onto the surface of the atomizer 12 through the first spray head 13 to wash away the impurities attached to the surface of the atomizer 12. For example, the first spray head 13 can be a nozzle structure that provides washing liquid through external pump pressure.

[0043] In addition, in order to remove the sediment at the bottom of the water tank 11, the device further includes one or more second spray heads 14. The second spray head 14 is also arranged inside the water tank 11, and the spraying direction is arranged towards the bottom of the water tank 11. When cleaning is needed, the washing liquid is sprayed onto the bottom of the water tank 11 through the second spray head 14 to carry the bottom impurities out with the water flow, and at the same time, the attached matter at the bottom of the water tank 11 can be washed away to achieve the flushing and cleaning effect inside the water tank 11. For example, the second spray head 14 can be a nozzle structure arranged at a suitable position inside the water tank 11 to cover the bottom area of the water tank 11.

[0044] Through the above structure, the atomization device 10 can effectively solve the problem of impurity accumulation on the surface of the atomizer 12 and the bottom of the water tank 11 in the traditional cold storage humidification device. The first spray head 13 can directly flush the atomizer 12 to remove the attachments on its surface, thereby maintaining the atomization efficiency and prolonging the service life of the atomizer 12. The second spray head 14 is directed at the bottom of the water tank 11 to effectively discharge the precipitated impurities, avoid the adverse effects of long-term accumulation of impurities on the operation of the device, and improve the cleanliness of the atomized particles. Therefore, the atomization device 10 is suitable for different environments such as fresh air systems, air conditioning systems or cold storage systems, has good self-cleaning and maintenance capabilities, and can improve the stability of operation.

[0045] In some embodiments, as shown in Figure 4 The atomization device 10 includes a control module 15, a first liquid level sensor 161 and a second liquid level sensor 162. The control module 15 is electrically connected to the atomizer 12 for controlling the operating state of the atomizer 12. The first liquid level sensor 161 is arranged in the water tank 11 and electrically connected to the control module 15 for detecting the first liquid level parameter of the water tank 11. The second liquid level sensor 162 is arranged in the water tank 11 and electrically connected to the control module 15 for detecting the second liquid level parameter of the water tank 11. The detection position of the first liquid level sensor 161 is higher than that of the second liquid level sensor 162.

[0046] The control module 15 can be a microcontroller (MCU), a programmable logic controller (PLC) or an embedded system, which receives signals from various sensors through pre-set program logic and controls the operating state of the execution components in the atomization device 10 according to these signals. For example, the control module 15 can receive signals from the liquid level sensor and decide whether to start the atomizer 12, whether to perform water replenishment or drainage operation according to the liquid level. Through the control module 15, the atomization device 10 can realize automatic and intelligent operation management, improve the reliability and safety of the device.

[0047] The first liquid level sensor 161 can adopt various forms such as float switch, ultrasonic sensor, capacitive sensor or photoelectric sensor. Its detection position is usually set to the upper limit of normal operating liquid level or the upper limit of safe liquid level in the water tank 11. When the liquid level of the water tank 11 reaches or exceeds the detection position of the first liquid level sensor 161, the control module 15 can receive the corresponding signal, thereby stopping water replenishment to prevent the liquid in the water tank 11 from overflowing the atomizer 12, thereby affecting the atomization effect and atomization speed.

[0048] The second liquid level sensor 162 can also be a float switch, ultrasonic sensor, capacitive sensor, or photoelectric sensor. Its detection position is typically set to the lower limit of the normal operating liquid level or the minimum safe liquid level in the water tank 11. When the liquid level in the water tank 11 is lower than the detection position of the second liquid level sensor 162, the control module 15 can receive a signal and take measures, such as stopping the atomizer 12 and starting water replenishment, to prevent the atomizer 12 from continuing to operate in a water-deficient state, which could lead to equipment damage.

[0049] By introducing a control module 15 and a first liquid level sensor 161 and a second liquid level sensor 162, the atomizing device 10 can achieve real-time monitoring and intelligent management of the liquid level in the water tank 11. Based on the liquid level parameters detected by the first and second liquid level sensors 161 and 162, the control module 15 can accurately determine whether the liquid level in the water tank 11 meets the atomization requirements of the atomizer 12. When the liquid level is too low, the control module 15 can promptly stop the atomizer 12 and start water replenishment, effectively preventing equipment damage caused by continuous operation of the atomizer 12 in a water-deficient state, thereby extending the service life of the atomizer 12. When the liquid level is too high, the control module 15 can stop water replenishment or start drainage to prevent the water tank 11 from overflowing and to prevent the water level from submerging the atomizer 12, thus affecting the atomization effect and speed. Through the above configuration, an intelligent liquid level control mechanism can be achieved, significantly improving the automation level and operational reliability of the atomizing device 10, reducing the need for manual intervention, and effectively ensuring the long-term stable operation of the equipment.

[0050] Among them, such as Figure 4 and Figure 5 As shown, the atomizing device 10 includes one or more of a first electrically controlled valve 163, a second electrically controlled valve 164, a third electrically controlled valve 165, and a fourth electrically controlled valve 165.

[0051] The first electrically controlled valve 163 is connected to the first nozzle 13, and the control module 15 is electrically connected to the first electrically controlled valve 163, used to control the start-up state of the first nozzle 13. The second electrically controlled valve 164 is connected to the second nozzle 14, and the control module 15 is electrically connected to the second electrically controlled valve 164, used to control the start-up state of the second nozzle 14. The third electrically controlled valve 165 is located at the drain outlet 114, and the control module 15 is electrically connected to the third electrically controlled valve 165, used to control the opening or closing of the drain outlet 114.

[0052] Water tank 11 is also provided with water inlet 116, and fourth electric control valve 166 is located at water inlet 116 to control the opening or closing of water inlet 116.

[0053] The first electric control valve 163, the second electric control valve 163, the third electric control valve 164, and the fourth electric control valve 165 can be in the form of solenoid valves, electric ball valves, or electric butterfly valves, and can drive the movement of the valve core or valve flap through an electric signal to open or close the fluid passage. For example, the first electric control valve 163, the second electric control valve 163, the third electric control valve 164, and the fourth electric control valve 165 can be in a normally closed state, and can remain open after receiving the control signal from the control module 15.

[0054] The first electric control valve 163 can receive the electric signal from the control module 15 and change the opening and closing state of the valve according to the signal, so as to accurately control whether the flushing liquid is supplied to the first spray head 13 to realize the flushing of the atomizer 12. The second electric control valve 164 can receive the instruction from the control module 15 and change the opening and closing state of the valve according to the signal, so as to control whether the flushing liquid is supplied to the second spray head 14 to realize the flushing of the bottom of the water tank 11.

[0055] The third electric control valve 165 is an electric control valve arranged at the drain port 114, and is used to control the discharge of the liquid in the water tank 11. The third electric control valve 165 can receive the instruction from the control module 15 to open or close the drain port 114, so as to automatically manage the drainage process of the water tank 11. For example, during the flushing process or when the atomized water needs to be replaced, the third electric control valve 165 can be driven to open by the control module 15 to discharge the liquid in the water tank 11.

[0056] The fourth electric control valve 166 is an electric control valve arranged at the water supplement port 116, and is used to control the supplement of the atomized water. The third electric control valve 165 can receive the instruction from the control module 15 to open or close the water supplement port 116, so as to automatically manage the supplement process of the atomized water in the water tank 11. For example, when the second liquid level sensor 162 detects that the liquid level in the water tank 11 is lower than the second liquid level parameter, the control module 15 can drive the fourth electric control valve 166 to open to supplement the atomized water into the water tank 11, and the supplement of the atomized water is stopped (i.e., the fourth electric control valve 166 is closed) when the first liquid level sensor 161 in the water tank 11 detects that the atomized water reaches the height of the first liquid level parameter.

[0057] Through the above technical solutions, the first electric control valve 163, the second electric control valve 164, the third electric control valve 165, and the fourth electric control valve 166 are introduced into the atomization equipment 10 and are electrically connected with the control module 15, so as to realize the automatic and accurate control of the first spray head 13, the second spray head 14, the drain port 114, and the water supplement port 116. The control module 15 can intelligently control the flushing and cleaning of the flushing liquid, the drainage of the water tank 11, and the supplement of the atomized water according to the preset program or the feedback of the liquid level sensor.

[0058] For example, when flushing is required, the control module 15 can precisely open the first and second electrically controlled valves 163 and 164 to ensure the supply of flushing liquid on demand. During the flushing process or after flushing is completed, automatic drainage is achieved by opening the third electrically controlled valve 165. When the water tank 11 is low on liquid, automatic water replenishment is performed by opening the fourth electrically controlled valve 166. This integrated electrically controlled valve system greatly improves the automation level and management efficiency of the atomization device 10, reduces manual intervention, ensures the accuracy of the flushing and water replenishment processes, effectively saves water resources, maintains the cleanliness of the ultrasonic atomizer 12 and the water tank 11, prolongs the service life of the device, and improves the stability of the atomization effect.

[0059] The ultrasonic atomizer 12 is an ultrasonic generator. An ultrasonic generator is a device that uses ultrasonic energy to atomize liquid into fine particles. Its working principle is usually to generate cavitation effects on the surface of the liquid through high-frequency vibrations (e.g., generated by a piezoelectric ceramic transducer), thereby breaking the liquid into extremely fine mist droplets. This atomization method can produce uniform and small-particle mist droplets, with the advantages of high atomization efficiency and relatively low energy consumption. The ultrasonic generator can be set up as a single or multiple units and can be installed at the bottom of the water tank 11 or other suitable positions as needed to ensure that the liquid is fully atomized.

[0060] By specifically defining the atomizer 12 as an ultrasonic generator, the present application can significantly improve the atomization efficiency, produce smaller and more uniform mist droplets, and thus optimize the humidification effect. The ultrasonic atomization technology itself has the characteristics of not being prone to fouling, and in combination with the first and second spray heads 13 and 14 provided in the water tank 11 to flush the atomizer 12 and the bottom of the water tank 11, it can effectively reduce the accumulation of dirt and scale on the surface of the ultrasonic generator, prolong its service life, reduce maintenance frequency and operating energy consumption. This ensures that the atomization device 10 can provide a high-quality atomization effect stably for a long time, improves the reliability and user experience of the device.

[0061] In some embodiments, as shown in FIGS. 1A and 1B, the number of atomizers 12 is one, and the atomizer 12 is disposed at the bottom of the water tank 11. Figure 4 and Figure 6 As shown in FIGS. 2A and 2B, the number of atomizers 12 is multiple, and the multiple atomizers 12 are disposed at the bottom of the water tank 11. The number of first spray heads 13 is multiple, and one first spray head 13 is disposed towards one atomizer 12.

[0062] By providing multiple atomizers 12, more mist can be generated, thereby improving the atomization speed and the ability to atomize and humidify the air, and thus meeting the needs of larger spaces or higher humidification efficiency. The multiple atomizers 12 are disposed at the bottom of the water tank 11 to ensure that they can be partially immersed in the liquid to be atomized and that the mist generated by atomization can be evenly diffused upwards. The atomizers 12 can be arranged in an array, for example, in a matrix form or distributed along the edge of the bottom of the water tank 11, to optimize the atomization effect and space utilization.

[0063] On this basis, the first spray head 13 is used to spray the washing liquid towards the atomizer 12 to remove the scale, mineral deposits or other contaminants that may accumulate on the surface of the atomizer 12. When the number of atomizers 12 is multiple, in order to ensure that each atomizer 12 can be effectively and thoroughly cleaned, the number of first spray heads 13 is also increased to multiple. And each first spray head 13 is accurately positioned and oriented, so that the washing liquid sprayed by it can directly and concentratedly act on the corresponding atomizer 12. This one-to-one configuration ensures that the washing liquid can efficiently cover the key working surface of the atomizer 12, thereby removing the dirt to the greatest extent and maintaining the optimal working state of the atomizer 12.

[0064] In some embodiments, as shown in Figure 2 and Figure 4 , the number of second spray heads 14 is multiple, and the multiple second spray heads 14 are spaced apart in the water tank 11. In the water tank 11, the second spray head 14 is also arranged towards the drain 114.

[0065] The multiple second spray heads 14 can be reasonably configured according to the size, shape of the water tank 11 and the layout of the atomizer 12, for example, can be in a matrix, ring or along the bottom edge of the water tank 11. These spray heads can be fixedly installed or have a certain adjustment angle to ensure that the washing liquid can cover most of the area at the bottom of the water tank 11. By increasing the number of spray heads and spacing them, the coverage of the washing liquid can be significantly expanded, and the efficiency of flushing the dirt at the bottom of the water tank 11 can be improved, avoiding dirt residues caused by flushing dead angles.

[0066] In the water tank 11, the second spray head 14 can also be arranged towards the drain 114. This means that at least one second spray head 14 or part of the second spray heads 14 is oriented so that its spraying direction points to the drain 114 of the water tank 11. This arrangement can be achieved by adjusting the installation angle of the spray head, the direction of the nozzle or selecting a nozzle with a specific spraying mode. By spraying the flow directly to the area of the drain 114, it aims to focus on flushing the area of the drain 114, prevent dirt from accumulating at the drain 114, ensure smooth drainage, and help to flush the dirt at the bottom of the water tank 11 more effectively to the drain 114.

[0067] In some embodiments, as shown in Figure 1 and Figure 2 , the atomization device 10 further comprises a fan 17, and the water tank 11 is further provided with an air inlet 115, and the fan 17 is arranged at the air inlet 115 to drive air to flow through the air inlet 115, the water tank 11 and the air outlet 113 in sequence. As shown in Figure 4 , the fan 17 is electrically connected with the control module 15.

[0068] By introducing the fan 17 and the air inlet 115 in the atomization device 10, and electrically connecting the fan 17 with the control module 15, the air can be actively and forcibly driven to flow through the air inlet 115, the water tank 11, and the air outlet 113 in sequence. This forced air circulation mechanism effectively solves the problem of mist stagnation or uneven diffusion in the water tank 11, ensuring that the mist generated by the atomizer 12 can be efficiently and uniformly discharged from the water tank 11, thereby significantly improving the humidification efficiency and mist delivery capacity of the atomization device 10. At the same time, the electrical connection between the fan 17 and the control module 15 allows the operating state of the fan 17 to be intelligently regulated according to actual needs, such as adjusting the air volume according to the target humidity or the operating state of the atomizer 12, further optimizing the performance of the atomization device 10 and achieving precise control and energy-saving operation of the humidification process, avoiding unnecessary energy waste.

[0069] In some embodiments, as shown in Figure 3 and Figure 5 The atomization device 10 further comprises a water baffle 18, which is arranged between the air inlet 115 and the atomizer 12 in the water tank 11.

[0070] The water baffle 18 is a physical barrier for blocking or changing the direction of water flow, water droplets, or atomized liquid movement. It can adopt various structural forms, such as flat, arc-shaped, or grating, and can be made of corrosion-resistant and easy-to-clean materials such as plastic or stainless steel. The water baffle 18 can be installed vertically or obliquely inside the water tank 11, and its size and position should ensure that it can effectively cover the main air flow channel between the air inlet 115 and the atomizer 12, and can be tightly attached to the inner wall of the water tank 11.

[0071] As a physical barrier, the water baffle 18 can effectively intercept the atomized liquid generated by the atomizer 12 and the fan 17 that may splash into the air inlet 115 in the water tank 11, thereby avoiding the fan 17 from being in a humid or waterlogged harsh working condition, which is beneficial to improve the service life and operating stability of the fan 17.

[0072] It should be noted that the air inlet 115 and the air outlet 113 can be arranged on the same side of the water baffle 18, but the atomizer 12 is located on the other side of the water baffle 18. During the process of air flowing from the air inlet 115, the water tank 11, to the air outlet 113, the mist filled in the water tank 11 can be driven to flow out of the air outlet 113. Alternatively, the water baffle 18 can not be arranged at the air outlet 113 and part of the atomizer 12, but only needs to cover the area between the air inlet 115 and the corresponding atomizer 12.

[0073] In some embodiments, as shown in Figure 1 and Figure 3As shown, the water tank 11 comprises a shell 111 and a cover plate 112, the shell 111 is provided with an opening on one side, and the cover plate 112 is located at the opening and connected with the shell 111. The air inlet 115 and the air outlet 113 are arranged on the cover plate 112, and the drain port 114 is arranged on the bottom wall of the shell 111 opposite to the opening.

[0074] The shell 111 of the water tank 11 generally constitutes the main body of the water tank 11 for accommodating liquid and internal components, while the cover plate 112 covers the opening on one side of the shell 111 to form an openable structure. The shell 111 and the cover plate 112 can be connected in various ways, such as through bolts, buckles or hinges, and a sealing gasket is provided at the connection to ensure the sealing of the water tank 11 and prevent liquid leakage. This detachable arrangement allows users or maintenance personnel to easily open the water tank 11 and directly access the internal components such as the atomizer 12, the first spray head 13 and the second spray head 14, greatly simplifying the installation, cleaning and maintenance of the equipment.

[0075] By arranging the water tank 11 as a detachable structure comprising the shell 111 and the cover plate 112, and locating the cover plate 112 at the opening on one side of the shell 111, the atomizing device 10 of the present application greatly improves the maintainability and cleanability of the internal components of the water tank 11. When cleaning, repairing or replacing internal components of the equipment is required, users or maintenance personnel can easily open or remove the cover plate 112 to directly access the interior of the water tank 11, thereby simplifying the maintenance process and reducing the difficulty and time cost of maintenance.

[0076] At the same time, the air inlet 115 and the air outlet 113 are arranged on the cover plate 112, so that the components related to air flow can be more concentrated on the cover plate 112, optimizing the overall structural layout. In addition, the drain port 114 is arranged on the bottom wall of the shell 111 opposite to the opening, ensuring the complete drainage of the liquid in the water tank 11, avoiding dead angle water accumulation, helping to maintain the cleanliness of the interior of the water tank 11, and preventing the drainage operation from interfering with the internal maintenance operation, further improving the practicability and user experience of the equipment.

[0077] In a second aspect, as shown in the drawings, Figure 7 The present application also provides a cold storage refrigeration system 100, comprising the atomizing device 10 of the first aspect and the air cooler 20, and the air outlet 113 of the atomizing device 10 is arranged between the heat exchanger 21 and the air outlet 22 of the air cooler 20. Figure 1

[0078] ​By setting the air outlet 113 of the atomization device 10 between the heat exchanger and the air outlet of the air cooler 20, the mist generated by the atomization device 10 can be directly discharged from the air outlet 22 of the air cooler 20, thereby avoiding the influence of heating or cooling of the heat exchanger 21 on the air humidity, and achieving a better humidifying effect on the cold storage.

[0079] In addition, since the cold storage refrigeration system 100 adopts the atomization device 10 in the first aspect, it at least has all the beneficial effects brought by the technical solutions of the embodiments of the first aspect, which will not be repeated here.

[0080] In the second aspect, the embodiments of the present application also provide a control method of an atomization device, which is used to control the atomization device 10 in the first aspect, and the control method comprises the following steps: Starting the atomization device 10.

[0081] Obtaining the cumulative time of the atomizer 12 in the atomization state.

[0082] When the atomization water amount of the atomizer 12 reaches the first threshold value, determining whether the ratio of the cumulative time of the atomizer 12 to the preset time length is greater than the second threshold value.

[0083] If the ratio of the cumulative time to the preset time length is greater than the second threshold value, controlling the atomizer 12 to be closed and the drain 114 to be opened, and controlling the first nozzle 13 and the second nozzle 14 to be started.

[0084] After the first preset time length, controlling the first nozzle 13 and the second nozzle 14 to be closed, and after the second preset time length, controlling the drain 114 to be closed.

[0085] Controlling the atomization water to be supplemented into the water tank 11.

[0086] By combining the atomization water amount monitoring with the cumulative time ratio determination, the cleaning process can be automatically triggered before the atomization efficiency decreases. Specifically, the method intelligently determines the cleaning demand based on the change of the working time length of the atomizer 12, and when the ratio of the cumulative time to the preset time length exceeds the second threshold value (such as 1.1-1.3), it indicates that the impurity accumulation has affected the atomization efficiency, and at this time, the cleaning program is started. During the cleaning process, the atomizer 12 is first closed and the drain 114 is opened, and the first nozzle 13 and the second nozzle 14 are started to flush, and after the first preset time length (such as 120-300s), the nozzles are closed, and after the second preset time length (such as 10-20s), the drain 114 is closed, and finally the water is supplemented, which has a good cleaning effect.

[0087] Through the above technical solutions, the atomization device 10 can automatically complete the cleaning of the atomizer 12 and the bottom of the water tank 11 without affecting the normal humidifying function, effectively solves the problem of impurity accumulation, prolongs the service life of the device, and ensures the stability of the cold storage environment.

[0088] In some embodiments, before controlling the atomizer 12 to be closed and the drain 114 to be opened, and controlling the first nozzle 13 and the second nozzle 14 to be activated, the control method comprises the following steps: Detecting whether a cold storage humidification instruction is received.

[0089] If the cold storage humidification instruction is not received, controlling the atomizer 12 to be closed and the drain 114 to be opened, and controlling the first nozzle 13 and the second nozzle 14 to be activated.

[0090] If the cold storage humidification instruction is received, controlling the atomizer 12 to remain activated.

[0091] This step aims to determine whether the current system is in a special operating mode that requires priority to ensure the humidification function. The cold storage humidification instruction can be sent to the control module 15 of the atomization device 10 by an external control system (such as the central control system of the cold storage) through a wired or wireless communication interface.

[0092] In addition, it can also be manually set by the user on the device operation interface, or automatically generated when the environmental humidity detected by the internal sensor (such as the humidity sensor) is lower than the set value. The reception of this instruction is a key precondition for the system to decide whether to execute the cleaning process.

[0093] When the system does not receive the cold storage humidification instruction, it indicates that there is no special requirement for the continuity of humidification in the current environment, or the system is in a non-cold storage humidification mode. In this case, in order to ensure the cleaning and normal operation of the atomization device 10, the control module 15 will close the atomizer 12, stop the atomization operation, and open the drain 114 by controlling the third electric valve 165 to drain the water in the water tank 11. At the same time, the control module 15 controls the first nozzle 13 and the second nozzle 14 to be activated by controlling the first electric valve 163 and the second electric valve 164, to flush the atomizer 12 and the bottom of the water tank 11, to remove sediments and dirt, and to ensure the atomization efficiency and water quality.

[0094] When the system receives the cold storage humidification instruction, it means that the current cold storage environment has a continuous and strict requirement for humidity. In order to avoid the interruption of the cleaning process to the humidification task, the control module 15 will prioritize the continuous operation of the atomizer 12, even if the atomization water volume has reached the first threshold value and the cumulative time ratio is greater than the second threshold value. In this case, the cleaning process will be temporarily delayed, and the atomizer 12 will continue to remain activated to ensure that the humidity in the cold storage can be continuously maintained within the target range, thereby ensuring the quality and safety of the stored goods.

[0095] By the above technical solution, the atomization equipment 10 can intelligently determine whether it is currently in a special demand scenario of cold storage humidification when the trigger cleaning condition is met. When receiving a cold storage humidification instruction, the system will prioritize ensuring the continuous operation of the atomizer 12, thereby avoiding the interruption of humidification caused by the start of the cleaning process. This effectively solves the potential conflict between automatic cleaning and continuous humidification in application scenarios with high requirements for humidity continuity, ensuring the stability and continuity of the humidity in the cold storage environment, which is of great significance to ensuring the quality of the stored goods in the cold storage. At the same time, under the non-humidification instruction state, the system can still clean on time, ensuring the cleanliness and long-term efficient operation of the equipment.

[0096] The step of controlling the replenishment of atomized water into the water tank 11 includes: controlling the opening of the fourth electric control valve 166 until the first liquid level parameter is detected.

[0097] The first liquid level parameter is the rated replenishment height of the water tank 11.

[0098] The fourth electric control valve 166 is usually a valve that can be controlled by an electric signal to open or close, such as a solenoid valve or an electric valve. The fourth electric control valve 166 is arranged at the water replenishment port 116 of the water tank 11, and is used to accurately control the on-off of the water replenishment. When the control module 15 issues an opening instruction, the fourth electric control valve 166 opens to allow the external water source to enter the water tank 11 through the water replenishment port 116. When the control module 15 issues a closing instruction, the fourth electric control valve 166 closes to stop water replenishment.

[0099] The first liquid level parameter represents the rated replenishment height of the liquid in the water tank 11, i.e. the optimal liquid level required for the normal operation of the atomization equipment 10. This parameter is usually pre-set and stored in the control module 15. The detection of the first liquid level parameter is realized by the first liquid level sensor 161 arranged in the water tank 11. The first liquid level sensor 161 continuously monitors the actual liquid level in the water tank 11 and feeds back the detected liquid level information to the control module 15. When the feedback actual liquid level reaches or exceeds the pre-set first liquid level parameter, the control module 15 determines that the first liquid level parameter has been detected. Therefore, the control module 15 will send an opening signal to the fourth electric control valve 166 to open the water replenishment port 116 when water replenishment is needed. At the same time, the control module 15 continuously receives liquid level data from the first liquid level sensor 161. Once the first liquid level sensor 161 detects that the liquid level in the water tank 11 reaches or is slightly higher than the rated replenishment height represented by the first liquid level parameter, the control module 15 will immediately send a closing signal to the fourth electric control valve 166 to accurately stop the water replenishment process.

[0100] When the water supplement is needed in the atomization device 10, the control module 15 can accurately control the opening and closing of the fourth electrically controlled valve 166, and combine the real-time monitoring of the liquid level in the water tank 11 by the first liquid level sensor 161, to ensure that the liquid level in the water tank 11 can be accurately supplemented to the preset rated water supplement height. This accurate control method based on the liquid level parameter effectively avoids the problems of overflow caused by excessive water supplement or insufficient water supplement affecting the atomization efficiency in the traditional water supplement method, ensures that the atomization device 10 always operates in the best liquid level state, thereby improving the operation stability and reliability of the device, and at the same time realizes the saving and efficient use of water resources.

[0101] In some embodiments, as shown in FIG. 1 1, the first threshold value is the water consumption of the atomizer 12 between the first liquid level parameter and the second liquid level parameter in the water tank 11. Figure 7

[0102] The second liquid level parameter is the minimum atomization water height of the water tank 11.

[0103] The first threshold value is a key parameter for triggering the cleaning process of the atomization device 10, which represents the total water consumption of the atomizer 12 in a certain liquid level range. The first threshold value is not a fixed value, but is dynamically associated with the change of the liquid level in the water tank 11. Specifically, it refers to the total amount of liquid consumed by the atomizer 12 during the period when the liquid level in the water tank 11 drops from the first liquid level parameter (rated water supplement height) to the second liquid level parameter (minimum atomization water height). By accurately measuring or estimating the water consumption in this liquid level range, it can be ensured that the cleaning trigger condition is closely linked to the actual atomization water consumption. The second liquid level parameter is the minimum atomization water height that the liquid in the water tank 11 can reach. This parameter is usually detected by the second liquid level sensor 162. When the liquid level in the water tank 11 drops to this second liquid level parameter, it indicates that the atomization water in the water tank 11 has been consumed to the minimum safe or effective atomization level. The purpose of setting this parameter is to ensure that the atomizer 12 operates within the effective working liquid level range, and when the water is insufficient for effective atomization, the water supplement or cleaning process is triggered.

[0104] ​By the technical solution, the first threshold is accurately defined as the water consumption of the atomizer 12 between the first liquid level parameter and the second liquid level parameter, and the second liquid level parameter is explicitly defined as the lowest atomization water height of the water tank 11. The control method of the present application can more accurately determine the actual water consumption of the atomizer 12. When the water consumption of the atomizer 12 reaches the preset effective atomization water consumption (i.e. the water consumption from the rated water replenishment height to the lowest atomization water height), the system triggers the cleaning process. This avoids the problem of unreasonable cleaning cycle caused by inaccurate water consumption calculation, ensures that the cleaning operation is performed when necessary, thereby improving the effectiveness of cleaning, prolonging the service life of the atomizer 12, and optimizing the utilization efficiency of water resources. At the same time, combined with the judgment of the cumulative time, the timeliness and thoroughness of cleaning are further ensured.

[0105] In a fourth aspect, as shown in Figure 8 The control module 15 of the present application is a control device of the atomization equipment, which comprises a processor 151, a communication interface 152, a memory 153 and a communication bus 154. The processor 151, the communication interface 152 and the memory 153 communicate with each other through the communication bus 154. The memory 153 is used to store a computer program.

[0106] In an embodiment of the present application, the processor 151 is used to execute the computer program stored in the memory 153, so as to realize the execution steps of the control method of the atomization equipment in the second aspect.

[0107] The present application also provides a computer readable storage medium having a computer program stored thereon, and the computer program is executed by the processor to realize the execution steps of the control method of the atomization equipment in the second aspect.
