[0015] Compared with the prior art, the present invention provides an automatic atomizing spray device and an atomizing cooling method, which have the following beneficial effects:

[0016] 1. The automatic atomizing spray device and the atomizing cooling method are provided with a cleaning component. In the process of the adjustment rod driving the needle valve stem to move, the scraper on the needle valve stem will change with the distance between the liquid outlet and the outer side of the tapered end of the needle valve stem, and will expand and contract by a corresponding length on the needle valve stem, so that the scraper always contacts the inner wall of the liquid outlet when in the liquid outlet.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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 making creative efforts are within the scope of protection of the present invention. Example

[0028] See also Figures 1-8An automatic atomizing spray device and an atomizing cooling method include a main body 1 and a temperature sensor 6 arranged on the outside of the main body 1. The temperature sensor 6 is used to monitor the temperature value in the external environment. The main body 1 is provided with a nozzle 2, a drive component 5 and an adjustment mechanism 3. The nozzle 2 is connected to the end of the main body 1. The center of the nozzle 2 is provided with a liquid outlet 21 for spraying water. The drive component 5 includes a drive motor 51. The drive motor 51 is installed on the side of the bottom of the main body 1. The temperature sensor 6 is connected to the drive motor 51 through an electrical signal. The adjustment mechanism 3 includes an adjustment rod 31 and a cleaning component 4. The adjustment rod 31 is installed inside the main body 1. Cooperating with the drive motor 51, the drive 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 scraper 42 and a transmission rod 44. A plurality of retractable scrapers 42 are installed at the end of the needle valve rod 41 close to the liquid outlet 21. The end of the needle valve rod 41 away from the liquid outlet 21 is connected to the 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 in the same direction into the liquid outlet 21. At the same time, the needle valve rod 41 rotates on the adjusting rod 31 through the transmission rod 44, driving the scraper 42 to rotate, thereby removing scale on the inner wall of the liquid outlet 21.

[0029] Among them, when in use, when the temperature of the space where the device is located rises to a set value, the temperature sensor 6 on the outside of the main body 1 is triggered, and a signal is sent to the drive motor 51 of the drive assembly 5 to start the drive motor 51. Before the drive motor 51 is started, the adjustment rod 31 pushes the needle valve rod 41 to block the liquid outlet 21, and the scraper 42 shrinks 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 opposite direction, driving the adjustment rod 31 to drive the needle valve rod 41 to move the maximum distance in the direction away from the nozzle 2, thereby fully opening the blocked liquid outlet 21, so that the liquid outlet 21 sprays water with a maximum flow rate, which is atomized into a spray at the nozzle 2. The mist quickly cools down the space where it is located. In 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 scraper 42 contracted 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 forward, so that the scraper 42 abutting against the inner wall of the liquid outlet 21 rotates 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 scraper 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 the maximum distance in the direction away from the nozzle 2, the driving motor 51 stops rotating. When the needle valve stem 41 is completely withdrawn from the liquid outlet 21, the scraper 42 also extends out of the needle valve stem 41 to its 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 adjustment rod 31 to push the needle valve stem 41 toward the liquid outlet 21, pushing the needle valve stem 41 into the liquid outlet 21. As the needle valve stem 41 is pushed in, the flow rate of water sprayed from the liquid outlet 21 gradually decreases, thereby adjusting the amount of water mist sprayed from the nozzle 2. When the water mist sprayed from the nozzle 2 can maintain the temperature at a suitable temperature value, the drive motor 51 stops rotating, thereby saving water and avoiding water shortage. Excessive waste, during this process, the transmission rod 44 will drive the needle valve stem 41 to rotate in the opposite direction, and at the same time, the scraper 42 with the maximum length extended from the needle valve stem 41 will be reinserted into the liquid outlet 21 along with the needle valve stem 41, and will be gradually squeezed by the inner wall of the liquid outlet 21, and retracted to the corresponding length into the needle valve stem 41, and in the process of retraction, it will rotate with the needle valve stem 41 to clean the scale on the inner wall of the liquid outlet 21 in the opposite direction. When the device completes the work, the drive motor 51 continues to rotate in the opposite direction, driving the adjusting rod 31 to push the needle valve stem 41 to completely block the liquid outlet 21, so that the nozzle 2 stops spraying water mist. The scraper 42 is now completely retracted into the needle valve stem 41, waiting for the next work.

[0030] The difference from the above embodiment is that a liquid channel 11 is provided in the center of the main body 1, one end of the liquid channel 11 is connected to the liquid outlet 21, gas channels 13 are provided on both sides of the main body 1, and the gas channels 13 are respectively located on both sides of the liquid channel 11, a drive groove 15 is provided in the main body 1, a gear groove 16 is provided below the drive groove 15, the upper end of the gear groove 16 is connected to the lower end of the drive groove 15, and a motor groove 17 is provided on one side of the bottom of the main body 1, and the motor groove 17 is connected to the lower end of the gear groove 16.

[0031] The difference from the above embodiment is that the adjusting rod 31 is movably installed in the driving groove 15, and a transmission groove 311 is opened in the 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, and the mounting seat 32 is connected to the transmission groove 311. The mounting seat 32 is located at the end of the transmission groove 311 away from the nozzle 2.

[0032] The difference from the above embodiment is that a driven rack 33 is fixedly installed on the lower side of the adjusting rod 31, and the driven rack 33 is located at the end of the transmission groove 311 away from the nozzle 2. A traction spring 34 in a stretched state is fixedly connected between the end of the adjusting rod 31 away from the nozzle 2 and the inner wall of the driving groove 15.

[0033] The difference from the above embodiment is that the needle valve rod 41 is located in the liquid channel 11, and the end of the needle valve rod 41 facing the liquid outlet 21 is tapered. The outer diameter of the tapered end of the needle valve rod 41 matches the inner diameter of the liquid outlet 21. A plurality of receiving grooves 411 are provided on the tapered end of the needle valve rod 41. The receiving grooves 411 are evenly distributed on the tapered end of the needle valve rod 41 in a circular shape. There is a distance between the receiving grooves 411 and the top end of the tapered end of the needle valve rod 41. The end of the scraper 42 close to the liquid outlet 21 is rotatably installed in the receiving groove 411. The scraper 42 is trapezoidal, and the upper side of the scraper 42 is an arc surface that matches the outer side of the tapered end of the needle valve rod 41. An elastic spring 43 is fixedly connected between the bottom of the scraper 42 and the bottom of the receiving groove 411. The spring 43 pushes the arc surface side of the scraper 42 out of the receiving groove 411.

[0034] 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 scraper 42 is completely retracted in the receiving groove 411 under the pressure of the inner wall of the liquid outlet 21. The arc surface of the scraper 42 fits with the outer side of the tapered end of the needle valve rod 41, thereby ensuring the sealing effect of the needle valve rod 41 on the liquid outlet 21 and allowing the reed 43 to accumulate force. When the needle valve rod 41 is pulled out of 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, and the accumulated force The reed 43 with force pushes the scraper 42 retracted in the receiving groove 411 outward, so that the arc surface of the scraper 42 always fits against the inner wall of the liquid outlet 21. When the tapered end of the needle valve stem 41 is completely pulled out of the liquid outlet 21, the reed 43 pushes the scraper 42 to extend from the receiving groove 411 to its maximum length. When the needle valve stem 41 is inserted into the liquid outlet 21 again, the scraper 42 extending from the receiving groove 411 is squeezed by the inner wall of the liquid outlet 21 again, thereby shrinking back into the receiving groove 411 and storing force in the reed 43.

[0035] The difference from the above embodiment is that the transmission rod 44 is coaxially 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 fixedly connected to the end of the transmission rod 44 close to the mounting seat 32, and a worm 46 is rotatably installed on the mounting seat 32, the worm 46 cooperates with the worm gear 45, and the upper end of the worm 46 is coaxially fixedly connected to the transmission gear 47.

[0036] Among them, when the adjusting rod 31 pulls the needle valve rod 41 out of the liquid outlet 21, the transmission gear 47 drives the worm 46 to rotate in the opposite direction, and the worm 46 drives the worm wheel 45 to drive the transmission rod 44 to rotate forward, thereby driving the needle valve rod 41 to rotate in the same direction as the transmission rod 44, so that the scraper 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 forward, and the worm 46 drives the worm wheel 45 to drive the transmission rod 44 to rotate in the opposite direction, thereby driving the needle valve rod 41 to move in the same direction as the transmission rod 44, so that the scraper 42 rotates from the other direction to scrape the scale on the inner wall of the liquid outlet 21.

[0037] The difference from the above embodiment is that the drive motor 51 is fixedly installed in the motor slot 17, and the output end of the drive motor 51 is fixedly connected to the drive gear 52, which is located on the lower side of the gear slot 16, and the upper side of the drive gear 52 is engaged with a driven gear 53, which is rotatably installed on the upper side of the gear slot 16, and the upper side of the driven gear 53 extends into the drive slot 15 and engages with the driven rack 33, and the drive rack 54 is fixedly installed on the upper side of the drive slot 15, and the drive rack 54 engages with the transmission gear 47.

[0038] 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 in the driving groove 15 in the direction away from the nozzle 2. 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 with 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 3 1 moves in the driving groove 15 toward the nozzle 2, and at the same time, the adjusting rod 31 drives the transmission gear 47 on the mounting seat 32 to move in the same direction, so that the transmission gear 47 rotates in the forward direction under the cooperation of the driving rack 54. During the movement of the adjusting rod 31, the tension spring 34 exerts a reverse tension on the adjusting rod 31, so that the driven rack 33 under the adjusting rod 31 can maintain a tight meshing with the driven gear 53. At the same time, the tension spring 34 also forms a buffer in the process of the adjustment rod 31 driving the needle valve rod 41 to move, thereby ensuring the normal operation of the device. Example

[0039] 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 located on both sides of the liquid outlet 21 , and the air outlets 22 are connected to the gas channel 13 .

[0040] The difference from the above embodiment is that a liquid infusion tube 12 and a gas infusion tube 14 are installed in sequence on the upper side of the main body 1. The liquid infusion tube 12 is connected to the end of the liquid channel 11 away from the nozzle 2, and the liquid infusion tube 12 is used to inject water into the liquid channel 11. The two gas infusion tubes 14 are respectively connected to the ends of the gas channels 13 on both sides away from the nozzle 2, and the gas infusion tubes 14 are used to inject gas into the gas channel 13.

[0041] Among them, after the needle valve stem 41 opens the liquid outlet 21, the liquid infusion tube 12 will inject water into the liquid channel 11, and the water in the liquid channel 11 will be sprayed out through the liquid outlet 21 of the nozzle 2. At the same time, the gas pipe 14 injects gas into the gas channel, and the gas in the gas channel 13 is sprayed out from the gas outlet 22, atomizing the water flow sprayed from the liquid outlet 21 into small droplet spray. After the needle valve stem 41 blocks the liquid outlet 21, the liquid infusion tube 12 and the gas pipe 14 stop working.

[0042] The present invention also provides an atomization cooling method, which uses an automatic atomization spraying device.

[0043] Working principle: When in use, when the temperature of the space where the device is located rises to the set value, the temperature sensor 6 on the outside of the main body 1 is triggered, and a signal is sent to the drive motor 51 of the drive assembly 5 to start the drive motor 51. Before the drive motor 51 is started, the tapered end of the needle valve rod 41 is inserted into the liquid outlet 21 to completely block the liquid outlet 21. At this time, the scraper 42 is completely retracted in the receiving groove 411 under the pressure of the inner wall of the liquid outlet 21. The arc surface of the scraper 42 fits with the outer side of the tapered end of the needle valve rod 41, thereby ensuring the sealing effect of the needle valve rod 41 on the liquid outlet 21 and storing force in the reed 43. When the drive motor 51 is started, the tapered end of the needle valve rod 41 is inserted into the liquid outlet 21 to completely block the liquid outlet 21. At this time, the scraper 42 is completely retracted in the receiving groove 411 under the pressure of the inner wall of the liquid outlet 21. The arc surface of the scraper 42 fits with the outer side of the tapered end of the needle valve rod 41, thereby ensuring the sealing effect of the needle valve rod 41 on the liquid outlet 21 and storing force in the reed 43. After receiving the start signal from the temperature sensor 6, the driving gear 52 drives the driven gear 53 to rotate in the opposite direction, thereby driving the driven rack 33 to drive the adjusting rod 31 to move the maximum distance in the driving groove 15 in the direction away from the nozzle 2, thereby fully opening the blocked liquid outlet 21. The liquid infusion pipe 12 will inject water into the liquid channel 11, and the water in the liquid channel 11 will be ejected through the liquid outlet 21 of the nozzle 2. At the same time, the gas in the gas channel 13 will be ejected from the gas outlet 22, and the water flow ejected from the liquid outlet 21 will be atomized into small droplets to quickly cool the surrounding space.

[0044] In 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, and the force-storing spring 43 pushes the scraper 42 contracted in the receiving groove 411 outward, so that the arc surface of the scraper 42 always fits the inner wall of the liquid outlet 21. At the same time, the adjusting rod 31 drives the transmission gear 47 on the mounting seat 32 to move in the same direction, so that the transmission gear 47 drives the worm 46 to rotate in the opposite direction under the cooperation of the driving rack 54, and the worm 46 drives the worm wheel 45 The transmission rod 44 is driven to rotate forward, thereby driving the needle valve rod 41 to rotate in the same direction as the transmission rod 44, so that the scraper 42 abutting against the inner wall of the liquid outlet 21 rotates 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 scraper 42 will be carried out of the liquid outlet 21 by the water flow and discharged from the nozzle 2. When the adjustment rod 31 moves the maximum distance in the direction away from the nozzle 2, the driving motor 51 stops rotating. At this time, the needle valve rod 41 is completely withdrawn from the liquid outlet 21, and the reed 43 pushes the scraper 42 to extend the maximum length from the receiving groove 411.

[0045] 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 adjustment rod 31 to push the needle valve rod 41 toward the liquid outlet 21, pushing the needle valve rod 41 into the liquid outlet 21. As the needle valve rod 41 is pushed in, the flow rate of water sprayed from the liquid outlet 21 gradually decreases, thereby adjusting the amount of water mist sprayed from the nozzle 2. When the water mist sprayed from the nozzle 2 can maintain the temperature at a suitable 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 opposite direction. At the same time, the scraper 42 extending to the maximum length from the needle valve stem 41 will be reinserted into the liquid outlet 21 as the needle valve stem 41, and will be gradually squeezed by the inner wall of the liquid outlet 21, and retracted to the corresponding length into the needle valve stem 41. During the retraction process, as the needle valve stem 41 rotates, the scale on the inner wall of the liquid outlet 21 is cleaned in the reverse direction. When the device completes the work, the drive motor 51 continues to rotate in the reverse direction, driving the adjusting rod 31 to push the needle valve stem 41 to completely block the liquid outlet 21, the liquid infusion pipe 12 and the gas infusion pipe 14 stop working, and the nozzle 2 stops spraying water mist. At this time, the scraper 42 is completely retracted into the needle valve stem 41, waiting for the next work.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
