[0014] Compared with the prior art, the present invention provides an automatic atomization spraying device and an atomization cooling method, which have the following beneficial effects: 1. For the automatic atomization spraying device and the atomization cooling method, through the arrangement of the cleaning component, during the process of the adjusting rod driving the needle valve rod to move, the scraping blade on the needle valve rod will extend and contract a corresponding length on the needle valve rod as the distance between the liquid outlet and the outer side of the tapered end of the needle valve rod changes, so that when the scraping blade is in the liquid outlet, it always abuts against the inner wall of the liquid outlet.

[0015] 2. For the automatic atomization spraying device and the atomization cooling method, through the cooperation of the driving component and the adjusting mechanism, when the driving motor drives the adjusting rod to drive the needle valve rod to completely open the liquid outlet, the nozzle sprays the maximum amount of water mist for rapid cooling. When the temperature drops to an appropriate value, the driving motor drives the adjusting rod to move an appropriate distance, so that the needle valve rod is inserted into the liquid outlet, reducing the water spraying amount of the liquid outlet, and making the water mist sprayed by the nozzle reduce to a level that can maintain the temperature value at an appropriate value, thereby saving the consumption of water resources.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] Please refer to Figures 1-8, an automatic atomizing spray device and an atomizing cooling method, comprising a main body 1 and a temperature sensor 6 arranged outside the main body 1. The temperature sensor 6 is used to monitor the temperature value in the external environment. A nozzle 2, a driving component 5 and an adjusting mechanism 3 are arranged on the main body 1. The nozzle 2 is connected to the end of the main body 1, and a liquid outlet 21 for spraying water is opened at the center of the nozzle 2. The driving component 5 includes a driving motor 51, and the driving motor 51 is installed on the side of the bottom of the main body 1. The temperature sensor 6 is connected to the driving motor 51 through an electric signal. The adjusting mechanism 3 includes an adjusting rod 31 and a cleaning component 4. The adjusting rod 31 is installed in the main body 1 and cooperates with the driving motor 51. The driving motor 51 can drive the adjusting rod 31 to move linearly in the main body 1. The cleaning component 4 includes a needle valve rod 41, a scraping blade 42 and a transmission rod 44. A plurality of retractable scraping blades 42 are installed at one end of the needle valve rod 41 close to the liquid outlet 21. One end of the needle valve rod 41 far from the liquid outlet 21 is connected to a transmission rod 44. The transmission rod 44 is installed in the adjusting rod 31. When the adjusting rod 31 moves, it drives the needle valve rod 41 to move into the liquid outlet 21 in the same direction. At the same time, the needle valve rod 41 rotates on the adjusting rod 31 through the transmission rod 44, driving the scraping blade 42 to rotate and removing the water scale on the inner wall of the liquid outlet 21.

[0020] Among them, during use, when the temperature of the space where the device is located rises to the set value, the temperature sensor 6 outside the main body 1 is triggered and sends a signal to the drive motor 51 of the drive assembly 5 to start the drive motor 51. Before the drive motor 51 starts, the adjusting rod 31 pushes the needle valve rod 41 to block the liquid outlet 21, and the scraping blade 42 contracts in the needle valve rod 41. When the drive motor 51 receives the start signal from the temperature sensor 6, it starts to rotate in the reverse direction, driving the adjusting rod 31 to drive the needle valve rod 41 to move away from the nozzle 2 by the maximum distance, thereby completely opening the blocked liquid outlet 21, enabling the liquid outlet 21 to eject the water flow with the maximum flow rate, atomizing into a spray at the nozzle 2 to quickly cool the space where it is located. During the process of the adjusting rod 31 driving the needle valve rod 41 away from the nozzle 2, as the needle valve rod 41 is withdrawn from the liquid outlet 21, the scraping blade 42 that contracts in the needle valve rod 41 gradually extends from the needle valve rod 41 and abuts against the inner wall of the liquid outlet 21. At the same time, the transmission rod 44 drives the needle valve rod 41 to rotate in the forward direction, causing the scraping blade 42 that abuts against the inner wall of the liquid outlet 21 to rotate along with the needle valve rod 41, thereby scraping off the scale on the inner wall of the liquid outlet 21. The scale scraped off by the scraping blade 42 will be carried out of the liquid outlet 21 by the water flow and discharged from the nozzle 2. When the adjusting rod 31 moves away from the nozzle 2 by the maximum distance, the drive motor 51 pauses. At this time, the needle valve rod 41 is completely withdrawn from the liquid outlet 21, and the scraping blade 42 also extends from the needle valve rod 41 to the maximum length. When the temperature drops to the appropriate temperature value, the temperature sensor 6 sends a signal to the drive motor 51 again, causing the drive motor 51 to start rotating in the forward direction, thereby driving the adjusting rod 31 to push the needle valve rod 41 towards the liquid outlet 21 and pushing the needle valve rod 41 into the liquid outlet 21. As the needle valve rod 41 is pushed in, the water flow rate ejected from the liquid outlet 21 gradually decreases, thereby adjusting the amount of water mist ejected from the nozzle 2. When the water mist ejected from the nozzle 2 can maintain the temperature at the appropriate temperature value, the drive motor 51 stops rotating, thereby saving water and avoiding excessive waste of water. During this process, the transmission rod 44 will drive the needle valve rod 41 to rotate in the reverse direction, and at the same time, the scraping blade 42 that extends from the needle valve rod 41 to the maximum length will be gradually squeezed by the inner wall of the liquid outlet 21 as the needle valve rod 41 is reinserted into the liquid outlet 21, retracting the corresponding length into the needle valve rod 41 and rotating along with the needle valve rod 41 during the retraction process to clean the scale on the inner wall of the liquid outlet 21 in the reverse direction. When the device finishes working, the drive motor 51 continues to rotate in the reverse direction, driving the adjusting rod 31 to push the needle valve rod 41 to completely block the liquid outlet 21, causing the nozzle 2 to stop spraying water mist. At this time, the scraping blade 42 is completely retracted into the needle valve rod 41 and waits for the next work.

[0021] The difference from the above embodiments is that a liquid passage 11 is provided at the center of the main body 1. One end of the liquid passage 11 communicates with the liquid outlet 21. Gas passages 13 are provided on both sides of the main body 1. The gas passages 13 are respectively located on both sides of the liquid passage 11. A driving groove 15 is provided in the main body 1. A gear groove 16 is provided below the driving groove 15. The upper end of the gear groove 16 communicates with the lower end of the driving groove 15. A motor groove 17 is provided on one side of the bottom of the main body 1. The motor groove 17 communicates with the lower end of the gear groove 16.

[0022] The difference from the above embodiments is that the adjusting rod 31 is movably installed in the driving groove 15. A transmission groove 311 is provided at one end of the adjusting rod 31 facing the nozzle 2. A mounting seat 32 is fixedly installed on the outer side of the adjusting rod 31. The mounting seat 32 communicates with the transmission groove 311. The mounting seat 32 is located at one end of the transmission groove 311 away from the nozzle 2.

[0023] The difference from the above embodiments is that a driven rack 33 is fixedly installed on the lower side of the adjusting rod 31. The driven rack 33 is located at one end of the transmission groove 311 away from the nozzle 2. A tension spring 34 in a stretched state is fixedly connected between one end of the adjusting rod 31 away from the nozzle 2 and the inner wall of the driving groove 15.

[0024] The difference from the above embodiments is that the needle valve rod 41 is located in the liquid passage 11. One end of the needle valve rod 41 facing the liquid outlet 21 is conical. The outer diameter of the conical end of the needle valve rod 41 fits the inner diameter of the liquid outlet 21. A plurality of receiving grooves 411 are provided on the conical end of the needle valve rod 41. The receiving grooves 411 are evenly distributed in a circular shape on the conical end of the needle valve rod 41. There is a certain distance between the receiving grooves 411 and the topmost end of the conical end of the needle valve rod 41. One end of the scraping blade 42 close to the liquid outlet 21 is rotatably installed in the receiving groove 411. The scraping blade 42 is trapezoidal, and the upper side of the scraping blade 42 is an arc surface that fits the outer side of the conical end of the needle valve rod 41. An elastic reed 43 is fixedly connected between the bottom of the scraping blade 42 and the bottom of the receiving groove 411. The reed 43 pushes the arc surface side of the scraping blade 42 out of the receiving groove 411.

[0025] Among them, when the device is not started, the tapered end of the needle valve rod 41 is inserted into the liquid outlet 21, completely blocking the liquid outlet 21. At this time, the scraping blade 42 is completely contracted in the receiving groove 411 under the extrusion of the inner wall of the liquid outlet 21. The arc surface of the scraping blade 42 fits against the outer side of the tapered end of the needle valve rod 41, thus ensuring the blocking effect of the needle valve rod 41 on the liquid outlet 21 and enabling the reed 43 to store energy. When the needle valve rod 41 is withdrawn from the liquid outlet 21, the distance between the outer side of the tapered end of the needle valve rod 41 and the inner wall of the liquid outlet 21 gradually increases. The energized reed 43 thus pushes the scraping blade 42 contracted in the receiving groove 411 outwards, making the arc surface of the scraping blade 42 always fit against the inner wall of the liquid outlet 21. After the tapered end of the needle valve rod 41 is completely withdrawn from the liquid outlet 21, the reed 43 will push the scraping blade 42 to extend to the maximum length from the receiving groove 411. When the needle valve rod 41 is inserted into the liquid outlet 21 again, the scraping blade 42 extending from the receiving groove 411 is again extruded by the inner wall of the liquid outlet 21, thus contracting back into the receiving groove 411 and enabling the reed 43 to store energy.

[0026] The difference from the above embodiment is that the transmission rod 44 is coaxially and fixedly connected to the other end of the needle valve rod 41. The transmission rod 44 is rotatably installed in the transmission groove 311, and a worm gear 45 is coaxially and fixedly connected to one end of the transmission rod 44 close to the mounting seat 32. A worm 46 is rotatably installed on the mounting seat 32. The worm 46 cooperates with the worm gear 45, and a transmission gear 47 is coaxially and fixedly connected to the upper end of the worm 46.

[0027] Among them, when the adjusting rod 31 withdraws the needle valve rod 41 from the liquid outlet 21, the transmission gear 47 drives the worm 46 to rotate in the reverse direction. The worm 46 drives the worm gear 45 to drive the transmission rod 44 to rotate in the forward direction, thereby driving the needle valve rod 41 to rotate in the same direction as the transmission rod 44, so that the scraping blade 42 rotates to scrape the scale on the inner wall of the liquid outlet 21. When the adjusting rod 31 inserts the needle valve rod 41 into the liquid outlet 21, the transmission gear 47 drives the worm 46 to rotate in the forward direction. The worm 46 drives the worm gear 45 to drive the transmission rod 44 to rotate in the reverse direction, thereby driving the needle valve rod 41 to move in the same direction as the transmission rod 44, so that the scraping blade 42 rotates to scrape the scale on the inner wall of the liquid outlet 21 from another direction.

[0028] The difference from the above embodiment is that the driving motor 51 is fixedly installed in the motor groove 17. The output end of the driving motor 51 is fixedly connected to a driving gear 52. The driving gear 52 is located below the gear groove 16. A driven gear 53 is meshed with the upper side of the driving gear 52. The driven gear 53 is rotatably installed on the upper side of the gear groove 16. The upper side of the driven gear 53 extends into the driving groove 15 and is meshed with the driven rack 33. A driving rack 54 is fixedly installed on the upper side of the driving groove 15. The driving rack 54 is meshed with the transmission gear 47.

[0029] Among them, when the driving motor 51 drives the driving gear 52 to rotate forward, the driving gear 52 drives the driven gear 53 to rotate in the reverse direction, thereby driving the driven rack 33 to drive the adjusting rod 31 to move away from the nozzle 2 in the driving groove 15. At the same time, the adjusting rod 31 will drive the transmission gear 47 on the mounting seat 32 to move in the same direction, so that the transmission gear 47 rotates in the reverse direction under the cooperation of the driving rack 54. When the driving motor 51 drives the driving gear 52 to rotate in the reverse direction, the driving gear 52 drives the driven gear 53 to rotate forward, thereby driving the driven rack 33 to drive the adjusting rod 31 to move towards the nozzle 2 in the driving groove 15. At the same time, the adjusting rod 31 will drive the transmission gear 47 on the mounting seat 32 to move in the same direction, so that the transmission gear 47 rotates forward under the cooperation of the driving rack 54. During the movement of the adjusting rod 31, the traction spring 34 in the stretched state applies a reverse pulling force to the adjusting rod 31, so that the driven rack 33 under the adjusting rod 31 can remain in close meshing with the driven gear 53. At the same time, the traction spring 34 will also form a buffer during the process of the adjusting rod 31 driving the needle valve rod 41 to move, thus ensuring the normal operation of the device. Embodiment

[0030] The difference from the above embodiment is that air outlets 22 are provided on both sides of the nozzle 2. The two air outlets 22 are correspondingly located on both sides of the liquid outlet 21, and the air outlets 22 are communicated with the gas channel 13.

[0031] The difference from the above embodiment is that an infusion tube 12 and an air supply tube 14 are sequentially installed on the upper side of the main body 1. The infusion tube 12 is communicated with the end of the liquid channel 11 far from the nozzle 2. The infusion tube 12 is used to inject water into the liquid channel 11. The two air supply tubes 14 are respectively communicated with the ends of the gas channels 13 far from the nozzle 2. The air supply tubes 14 are used to inject gas into the gas channels 13.

[0032] Among them, after the needle valve rod 41 opens the liquid outlet 21, the infusion tube 12 will inject water into the liquid channel 11. The water in the liquid channel 11 is sprayed out through the liquid outlet 21 of the nozzle 2. At the same time, the air supply tube 14 injects gas into the gas channel. The gas in the gas channel 13 is sprayed out from the air outlet 22, atomizing the water flow sprayed out from the liquid outlet 21 into small droplets for spraying. After the needle valve rod 41 blocks the liquid outlet 21, the infusion tube 12 and the air supply tube 14 stop working.

[0033] The present invention also provides an atomizing cooling method, which uses an automatic atomizing spraying device.

[0034] Working principle: During use, when the temperature in the space where the device is located rises to the set value, the temperature sensor 6 outside the main body 1 is triggered, sending a signal to the drive motor 51 of the drive assembly 5 to start the drive motor 51. Before the drive motor 51 starts, the tapered end of the needle valve rod 41 is inserted into the liquid outlet 21, completely blocking the liquid outlet 21. At this time, the wiper blade 42 is completely contracted in the storage groove 411 under the extrusion of the inner wall of the liquid outlet 21, and the arc surface of the wiper blade 42 fits against the outer side of the tapered end of the needle valve rod 41, thus ensuring the blocking effect of the needle valve rod 41 on the liquid outlet 21 and making the reed 43 store energy. When the drive motor 51 receives the start signal from the temperature sensor 6, the drive gear 52 drives the driven gear 53 to rotate in the reverse direction, thereby driving the driven rack 33 to drive the adjusting rod 31 to move in the drive groove 15 in the direction away from the nozzle 2 by the maximum distance, thus completely opening the blocked liquid outlet 21. The infusion tube 12 injects water into the liquid channel 11, and the water in the liquid channel 11 sprays out through the liquid outlet 21 of the nozzle 2. At the same time, the gas transmission tube 14 injects gas into the gas channel, and the gas in the gas channel 13 sprays out from the gas outlet 22, atomizing the water flow sprayed out from the liquid outlet 21 into small droplets for rapid cooling of the space where it is located; During the process of the adjusting rod 31 driving the needle valve rod 41 away from the nozzle 2, as the needle valve rod 41 is withdrawn from the liquid outlet 21, the distance between the outer side of the tapered end of the needle valve rod 41 and the inner wall of the liquid outlet 21 gradually increases. The energized reed 43 thus pushes the wiper blade 42 contracted in the storage groove 411 outwards, making the arc surface of the wiper blade 42 always fit against the inner wall of the liquid outlet 21. At the same time, the adjusting rod 31 will drive the transmission gear 47 on the mounting seat 32 to move in the same direction, causing the transmission gear 47 to drive the worm 46 to rotate in the reverse direction in cooperation with the drive rack 54. The worm 46 drives the worm gear 45 to drive the transmission rod 44 to rotate in the forward direction, thereby driving the needle valve rod 41 to rotate in the same direction as the transmission rod 44, making the wiper blade 42 against the inner wall of the liquid outlet 21 rotate with the needle valve rod 41, thus scraping the scale on the inner wall of the liquid outlet 21. The scale scraped off by the wiper blade 42 will be carried out of the liquid outlet 21 by the water flow and discharged from the nozzle 2. When the adjusting rod 31 moves in the direction away from the nozzle 2 by the maximum distance, the drive motor 51 pauses, and at this time, the needle valve rod 41 is completely withdrawn from the liquid outlet 21, and the reed 43 will push the wiper blade 42 to extend from the storage groove 411 to the maximum length; After the temperature drops to a suitable temperature value, the temperature sensor 6 sends a signal to the drive motor 51 again, causing the drive motor 51 to start rotating forward, thereby driving the adjusting rod 31 to push the needle valve rod 41 in the direction of the liquid outlet 21, and pushing the needle valve rod 41 into the liquid outlet 21. As the needle valve rod 41 is pushed in, the water flow rate sprayed from the liquid outlet 21 gradually decreases, thereby adjusting the amount of water mist sprayed by the nozzle 2. When the water mist sprayed by the nozzle 2 can maintain the temperature at a suitable temperature value, the drive motor 51 stops rotating, thereby saving water sources and avoiding excessive waste of water sources. During this process, the transmission rod 44 will drive the needle valve rod 41 to rotate in the reverse direction, and at the same time, the wiper blade 42 that extends the maximum length from the needle valve rod 41 will be gradually squeezed by the inner wall of the liquid outlet 21 as the needle valve rod 41 is reinserted into the liquid outlet 21, and retract the corresponding length into the needle valve rod 41, and rotate with the needle valve rod 41 during the retraction process to clean the scale on the inner wall of the liquid outlet 21 in the reverse direction. When the device finishes working, the drive motor 51 continues to rotate in the reverse direction, driving the adjusting rod 31 to push the needle valve rod 41 to completely block the liquid outlet 21, and the infusion tube 12 and the air delivery tube 14 stop working, causing the nozzle 2 to stop spraying water mist. At this time, the wiper blade 42 is completely retracted into the needle valve rod 41 and waits for the next work.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
