[0025] 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.
[0026] Please refer to Figure 1-7 , the present invention provides a technical solution: an anti-blocking spray gun for spraying architectural coatings, including: a spray gun body 1, a filter plate 5 is movably installed on one side of the inner cavity of the spray gun body 1, a connecting plate 501 is installed on the top of the filter plate 5, and auxiliary handles 502 are installed on both sides of the top of the connecting plate 501. Two fixed blocks 6 are installed on the surface of the top of the spray gun body 1, placing grooves 601 are opened on the surfaces of the two fixed blocks 6, fixing components 7 are arranged on one side of the two fixed blocks 6, a paint bucket 9 is installed on the other side of the top of the spray gun body 1, and a stirring component 10 is arranged inside the paint bucket 9. The stirring component 10 includes a motor 1001, the motor 1001 is fixedly embedded in the top of the paint bucket 9, a connecting rod 1002 is fixedly installed at the output end of the motor 1001, a plurality of stirring rods 1003 are installed on the surface of the connecting rod 1002, the plurality of stirring rods 1003 are evenly divided into four groups, and scrapers 1004 are connected to one end of each of the four groups of stirring rods 1003. Two T-shaped scrapers 1005 are installed at the bottom end of the surface of the connecting rod 1002.
[0027] Specifically, when spraying the building wall surface, the paint can be added into the interior of the paint bucket 9. Since a stirring assembly 10 is provided inside the paint bucket 9, the stirring assembly 10 can rotate and stir the paint inside the paint bucket 9. At this time, the motor 1001 operates and drives the connecting rod 1002 to rotate. During the rotation of the connecting rod 1002, multiple stirring rods 1003 on its surface will rotate and disperse the paint inside the paint bucket 9, which can effectively prevent the paint from caking. One end of each of the multiple stirring rods 1003 is connected to a scraping plate 1004. The scraping plate 1004 is attached to the inner wall surface of the paint bucket 9, so that the scraping plate 1004 can scrape off the paint on the inner wall of the paint bucket 9 during the stirring process, preventing the paint from adhering to the inner wall of the paint bucket 9. The bottom ends of the two T-shaped scraping plates 1005 have a certain arc, making them just fit on the surface of the bottom end of the inner cavity of the paint bucket 9, and can scrape the inner wall of the bottom of the inner cavity of the paint bucket 9 during the rotation of the connecting rod 1002, facilitating the cleaning of the interior of the paint bucket 9. At this time, the stirred paint is not likely to block the barrel during spraying. The stirred paint passes through the filter plate 5 in the conveying pipe inside the spray gun main body 1 to filter out impurities in the paint, improving the quality of the paint used. The two auxiliary handles 502 are connected to the filter plate 5 through the connecting plate 501, facilitating the removal of the filter plate 5 when cleaning the spray gun main body 1. The two fixing blocks 6 are installed at positions to cooperate with the clamping plate 8, and the clamping plate 8 can be fixedly placed on the top of the connecting plate 501 through the two fixing assemblies 7, thereby fixing the placement of the filter plate 5.
[0028] In one embodiment, a grip 2 is installed at the bottom of the spray gun main body 1, a card slot 3 is formed on one side of the top surface of the spray gun main body 1, and a nozzle 4 is installed on the front side of the spray gun main body 1.
[0029] Specifically, when spraying, the grip 2 can be held by hand, and by pressing the spray gun switch, the paint can be ejected from the inside of the nozzle 4, thus realizing spraying. The inside of the card slot 3 is used to install and use the filter plate 5, which can filter impurities from the stirred paint.
[0030] In one embodiment, the fixing assembly 7 includes a limit post 701. The limit post 701 is movably embedded on one side of the fixing block 6. A fixing plate 702 is installed on one side of the limit post 701. One side of the fixing plate 702 is connected to a spring 703, and the other end of the spring 703 is connected to the surface of the fixing block 6.
[0031] Specifically: The limit post 701 is movably embedded in the surface of the fixed block 6. The limit post 701 can be pulled out from the surface of the fixed block 6 through the fixed disk 702. At this time, since the fixed disk 702 is connected to the surface of the fixed block 6 through the spring 703, the limit post 701 can be connected by the spring 703 and a pulling force is generated during the extraction process. When the limit post 701 needs to be placed in place, the fixed disk 702 can be used to drive the limit post 701 to rebound and place under the action of the spring 703. The spring 703 can play a role in fixedly connecting the limit post 701.
[0032] In one embodiment, a clamping plate 8 is movably installed inside the two placement grooves 601. An auxiliary plate 801 is installed on the top of the clamping plate 8. Slots 802 are formed on both sides of the clamping plate 8.
[0033] Specifically: The clamping plate 8 can just be placed inside the two placement grooves 601, so that the positions of the clamping plate 8 are limited inside the two placement grooves 601. The auxiliary plate 801 can facilitate the taking of the clamping plate 8. The slots 802 formed on both sides of the clamping plate 8 are convenient for using the two limit posts 701 to limit it. When the two limit posts 701 are located inside the two slots 802, the clamping plate 8 can limit and fix the installation position of the filter plate 5.
[0034] In one embodiment, a feeding bin 901 is installed through one side of the top of the paint bucket 9. A cover plate 902 is installed on the top of the feeding bin 901. A handle 903 is installed on the surface of the cover plate 902.
[0035] Specifically: When adding paint to the inside of the paint bucket 9, the handle 903 can be used to remove the cover plate 902 from the top of the feeding bin 901, and the inside of the feeding bin 901 communicates with the inside of the paint bucket 9. Thus, the paint can be directly added to the inside of the paint bucket 9 through the inside of the feeding bin 901. A sealing ring is installed around the inner side of the cover plate 902, which can effectively block the feeding port at the top of the feeding bin 901 and prevent the paint from flowing out.
[0036] In one embodiment, both of the two limit posts 701 are located inside the two springs 703. Both of the two limit posts 701 are movable inside the two placement grooves 601. Both of the two limit posts 701 are movable inside the two slots 802.
[0037] Specifically, the limit post 701 is located inside the spring 703, enabling the limit post 701 to be pulled and placed under the action of the spring 703, thereby facilitating the connection of the spring 703 to the limit post 701. After the two limit posts 701 are embedded through the surface of the fixing block 6, they will just enter the inside of the slot 802. When both of the two limit posts 701 are inside the two slots 802, the clamping plate 8 can be fixedly placed on the top of the connecting plate 501 at this time, so as to fix the placement of the filter plate 5. When the clamping plate 8 is removed, one end of the limit post 701 will enter the inside of the placement groove 601.
[0038] In one embodiment, the filter plate 5 is movable inside the card slot 3, and the two fixing blocks 6 are respectively located on both sides of the card slot 3.
[0039] Specifically, the filter plate 5 is movably placed inside the card slot 3, which is convenient for disassembly and installation after the spraying is completed. The two fixing blocks 6 are respectively located on both sides of the card slot 3. After the filter plate 5 is placed inside the card slot 3, the connecting plate 501 on its top will be located between the two fixing blocks 6. By placing the clamping plate 8, the top of the connecting plate 501 can be fitted and fixed, so as to achieve the fixing effect on the installation of the filter plate 5.
[0040] Working principle: When the equipment needs to be used for work, first use the handle 903 to remove the cover 902 from the top of the feeding bin 901, add the paint into the interior of the paint bucket 9 through the feeding bin 901, and start the motor 1001. The operation of the motor 1001 will drive the connecting rod 1002 to rotate. At this time, the multiple stirring rods 1003 on the surface of the connecting rod 1002 rotate and stir the paint to prevent the paint from agglomerating and clogging. In addition, the multiple stirring rods 1003 will drive the multiple scrapers 1 during the rotation process. 004 scrapes the inner wall of the paint bucket 9 to scrape off the paint adhering to the inner wall of the paint bucket 9 for stirring. By setting the stirring component 10, the paint can be stirred to break up the agglomerated paint, thereby avoiding uneven spraying of the paint when spraying on the building wall, which affects the spraying efficiency. After stirring evenly, press the spray gun switch, and the paint inside the paint bucket 9 can be filtered and sprayed through the filter plate 5. The filter plate 5 can filter the impurities remaining in the paint, so that the impurities adhere to the surface of the filter plate 5. At this time, After passing through the filter plate 5, the paint is sprayed onto the building wall through the nozzle 4. When the filter plate 5 needs to be disassembled and cleaned, the two fixing plates 702 can be used to drive the two limiting posts 701 to separate from the inside of the two slots 802 respectively. At this time, the auxiliary plate 801 can be used to remove the card plate 8, and then the two auxiliary handles 502 are used to pull the filter plate 5 out from the inside of the card slot 3. When the filter plate 5 is cleaned, the filter plate 5 is placed inside the card slot 3 again, and the two limiting posts 701 are pulled out to both sides so that the card plate 8 is just placed inside the two placement slots 601. The two fixing plates 702 are loosened, so that the two limiting posts 701 rebound into the inside of the slot 802 under the action of the two springs 703, so that the card plate 8 can be fixed on the top of the connecting plate 501. By filtering the stirred paint, impurities in the paint can be effectively trapped on one side of the filter plate 5, so that better quality paint can be obtained when the nozzle 4 is sprayed, and clogging of the spray gun can be avoided, which can effectively improve the efficiency of the spray gun.
