Description

Technical Field

[0001] This utility model relates to the technical field of spray cooling devices, and specifically to an anti-clogging nozzle for a spray cooling device. Background Technology

[0002] The urban heat island effect refers to the phenomenon where urban surface temperatures are higher than those in suburban areas, especially with significant nighttime temperature differences. Due to factors such as dense urban buildings and vehicle emissions, heat accumulates in cities, leading to increased urban temperatures and discomfort for residents. To alleviate this phenomenon, in addition to increasing urban green spaces—a natural method—sprinkler cooling devices incorporate the cooling principles of green spaces. By installing sprinkler systems in specific areas (such as around green areas or on building surfaces), they utilize the heat absorption properties of water evaporation to lower the surrounding environment's temperature. These devices can be used alone in green spaces or combined with green areas to form more effective cooling systems.

[0003] During the use of a sprinkler cooling device, the water source may contain various impurities and particulate matter, such as sand, soil, and organic matter. When these impurities enter the sprinkler head through the pipes, they can easily deposit inside the sprinkler head or adhere to the sprinkler head surface, causing blockage. Furthermore, minerals such as calcium and magnesium in the water can form scale inside the pipes after prolonged use. With the impact of the water flow, this scale can also flow into the sprinkler head and gradually accumulate, leading to nozzle blockage. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging nozzle for a spray cooling device to overcome the aforementioned defects in the prior art.

[0005] An anti-clogging nozzle for a spray cooling device includes a water supply pipe connected to the spray cooling device. A connecting mechanism is detachably connected between the water supply pipe and the nozzle. An annular baffle is fixedly connected to the inner wall of the connecting mechanism. A filter mechanism is detachably connected to the annular baffle. A sealing component is provided inside the connecting mechanism. The sealing component and the filter mechanism are connected by a telescopic component.

[0006] Preferably, the connecting mechanism includes a connecting pipe, and the nozzle is threadedly connected to the threaded groove on the inner wall of the upper end of the connecting pipe through the external threaded pipe one at its lower end, and the external threaded pipe two at the lower end of the connecting pipe is threadedly connected to the threaded groove on the inner wall of the upper end of the water supply pipe. An annular baffle is provided on the inner wall of the connecting pipe.

[0007] Preferably, the filtration mechanism includes an annular filter plate, which is located above an annular baffle and has a frustum-shaped filter cylinder below it. The diameter of the annular filter plate is the same as the inner diameter of the connecting pipe, and a connecting plate is provided at the lower end of the filter cylinder.

[0008] Preferably, the telescopic assembly includes an outer rod located at the lower end of the connecting plate, a sliding cavity is provided inside the outer rod, a spring is fixedly connected to the inner wall of the sliding cavity, an inner rod is slidably connected in the sliding cavity, and the lower end of the spring is connected to the inner rod.

[0009] Preferably, the sealing assembly includes a fixing block fixedly connected to the inner wall of the connecting pipe, the upper end of the fixing block having a first groove, the lower end of the fixing block having a second groove communicating with the first groove, and the lower end of the inner rod having a sealing plate that mates with the first groove.

[0010] Preferably, the cross-sections of the first groove, the second groove, and the sealing plate are all isosceles trapezoids.

[0011] The beneficial effects achieved by this utility model are as follows:

[0012] This application installs a connecting mechanism between the nozzle and the water supply pipe. When water is supplied to the nozzle, the water flow applies pressure to the sealing plate, causing the sealing plate to move upward and the telescopic component to be compressed. This allows the water to flow normally, while impurities and other particles in the water flow are intercepted by the filtration mechanism, effectively preventing impurities and other particles from entering the nozzle and causing blockage. When the spraying operation stops, the telescopic component extends, pushing the sealing plate to connect with the groove on the fixed block, thereby sealing the pipe. This keeps impurities and other particles inside the connecting mechanism, making it easy to remove the connecting mechanism and clean the impurities and other particles inside.

[0020] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of this utility model, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the concept and technical solution of this utility model.

[0021] like Figure 1 As shown, this utility model provides an anti-clogging nozzle for a spray cooling device, including a water supply pipe 1 connected to the spray cooling device. A connecting mechanism 5 is detachably connected between the water supply pipe 1 and the nozzle 3. An annular baffle 6 is fixedly connected to the inner wall of the connecting mechanism 5. A filter mechanism 7 is detachably connected to the annular baffle 6. A sealing component 8 is provided inside the connecting mechanism 5. The sealing component 8 and the filter mechanism 7 are connected by a telescopic component 9.

[0022] like Figure 2 , 3 As shown, the connecting mechanism 5 includes a connecting pipe 501. The nozzle 3 is threadedly connected to the threaded groove 502 on the inner wall of the upper end of the connecting pipe 501 through the external threaded pipe 4 at its lower end. The external threaded pipe 503 at the lower end of the connecting pipe 501 is threadedly connected to the threaded groove 2 on the inner wall of the upper end of the water supply pipe 1. An annular baffle 6 is provided on the inner wall of the connecting pipe 501.

[0023] Specifically, the filter mechanism 7 is first placed on the annular baffle 6 on the inner wall of the connecting pipe 501. At this time, the telescopic component 9 is in its natural state and at its longest length, so that the sealing plate 804 at the lower end of the inner rod 904 extends into the groove 802 on the fixing block 801, sealing the groove 802. Then, the external threaded pipe 503 at the lower end of the connecting pipe 501 is threadedly connected to the threaded groove 2 on the water supply pipe 1. Then, the nozzle 3 is threadedly connected to the threaded groove 502 on the connecting pipe 501 through the external threaded pipe 4. The nozzle 3 can then be connected to the water supply pipe 1 through the connecting mechanism 5. The lower end of the external threaded pipe 4 abuts against the upper surface of the annular filter plate 701. The lower end of the external threaded pipe 4 and the annular baffle 6 simultaneously squeeze the annular filter plate 701, thereby fixing the filter mechanism 7.

[0024] like Figure 4 , 5As shown, the filtration mechanism 7 includes an annular filter plate 701, which is located above the annular baffle 6 and has a frustum-shaped filter cylinder 702 on its lower side. The diameter of the annular filter plate 701 is the same as the inner diameter of the connecting pipe 501, and a connecting plate 703 is provided at the lower end of the filter cylinder 702.

[0025] Specifically, when water flows through the filtration mechanism 7, the annular filter plate 701 and the filter cylinder 702 can intercept impurities and other particles in the water flow, thereby preventing impurities and other particles from flowing into the nozzle 3. Compared with using a single cylindrical filter cylinder, the combination of the annular filter plate 701 and the filter cylinder 702 can store more impurities and other particles in the connecting pipe 501.

[0026] like Figure 6 As shown, the telescopic assembly 9 includes an outer rod 901 located at the lower end of the connecting plate 703. A sliding cavity 902 is provided inside the outer rod 901. A spring 903 is fixedly connected to the inner wall of the sliding cavity 902. An inner rod 904 is slidably connected in the sliding cavity 902. The lower end of the spring is connected to the inner rod 904. The spring 903 has low stiffness and preload. The force of the spring 903 on the sealing plate 804 is less than the impact force of the water flow on the sealing plate 804, so as not to affect the exposure of the groove 802, allowing the water flow to flow normally into the nozzle 3.

[0027] Specifically, when the water supply is stopped, the spring 903 releases energy, giving the sealing plate 804 a slight push, allowing the sealing plate 804 to move downward quickly and seal the groove 802, thus leaving impurities and other particles inside the connecting pipe 501. By reversing the above operation, the connecting mechanism 5 can be removed from the water supply pipe 1, and the nozzle 3 can also be removed, making it easier to pour out the filter mechanism 7 inside the connecting pipe 501 and the impurities and other particles inside the connecting pipe 501, so as to clean the filter mechanism 7 and the inside of the connecting pipe 501. After reinstallation, it can be used again.

[0028] In addition, the sealing assembly 8 includes a fixing block 801 fixedly connected to the inner wall of the connecting pipe 501. The upper end of the fixing block 801 is provided with a groove 802, and the lower end of the fixing block 801 is provided with a groove 803 communicating with the groove 802. The lower end of the inner rod 904 is provided with a sealing plate 804 that cooperates with the groove 802.

[0029] Specifically, when water is supplied to the water supply pipe 1, the water flows into the connecting pipe 501. Under the impact of the water flow and the pressure inside the pipe, the sealing plate 804 is pushed upward, causing the sealing plate 804 to gradually move away from the groove 802. The groove 802 is opened, allowing the water to continue to flow upward. During the upward movement of the sealing plate 804, the inner rod 904 also moves upward, and the spring 903 is compressed and stores energy.

[0030] In addition, the cross-sections of the first groove 802, the second groove 803, and the sealing plate 804 are all isosceles trapezoids. The cross-sections of the first groove 802 and the sealing plate 804 are isosceles trapezoids to facilitate the quick alignment of the sealing plate 804 with the first groove 802, thereby sealing the first groove 802 and keeping impurities and other particles inside the connecting pipe 501. The cross-section of the second groove 803 is an isosceles trapezoid to facilitate the flow of impurities and other particles.

[0031] Detailed implementation methods and principles:

[0032] In use, first place the filter mechanism 7 on the annular baffle 6 on the inner wall of the connecting pipe 501. At this time, the telescopic component 9 is in its natural state and at its longest length, so that the sealing plate 804 at the lower end of the inner rod 904 extends into the groove 802 on the fixing block 801, sealing the groove 802. Then, thread the external threaded pipe 503 at the lower end of the connecting pipe 501 to the threaded groove 2 on the water supply pipe 1. Then, thread the nozzle 3 to the threaded groove 502 on the connecting pipe 501 through the external threaded pipe 4. The nozzle 3 can then be connected to the connecting machine. The filter mechanism 7 is connected to the water supply pipe 1, and the lower end of the external threaded pipe 4 abuts against the upper surface of the annular filter plate 701. The lower end of the external threaded pipe 4 and the annular baffle 6 simultaneously squeeze the annular filter plate 701, thereby fixing the filter mechanism 7. At this time, the spray cooling device is activated to supply water to the water supply pipe 1. When the water flows into the connecting pipe 501, under the impact of the water flow and the pressure inside the pipe, the sealing plate 804 is pushed upward, causing the sealing plate 804 to gradually move away from the groove 802, so that the water can continue to flow upward. As the sealing plate 804 moves upward, the inner rod 904 also moves upward, compressing the spring 903 and storing energy. When water flows through the filter mechanism 7, impurities and other particles in the water are intercepted and adhere to the surfaces of the annular filter plate 701 and the filter cylinder 702, effectively preventing impurities and other particles from entering the nozzle 3 and thus avoiding clogging. When the water flow from the nozzle 3 is slow and weak, it indicates that too many impurities and other particles have accumulated inside the connecting pipe 501. At this time, the water supply is stopped, and the spring 903 is released. Energy is applied to the sealing plate 804 with a slight pushing force, allowing the sealing plate 804 to move downwards quickly and seal the groove 802, thus leaving impurities and other particles inside the connecting pipe 501. By reversing the above operation, the connecting mechanism 5 can be removed from the water supply pipe 1, and the nozzle 3 can also be removed, making it easier to pour out the filter mechanism 7 inside the connecting pipe 501 and the impurities and other particles inside the connecting pipe 501, so as to clean the filter mechanism 7 and the inside of the connecting pipe 501. After reinstallation, it can be used again.
