Description
Technical Field
[0001] This invention relates to the field of interior decoration equipment technology, specifically to an interior decoration wall spraying device and method. Background Technology
[0002] Interior wall spraying is a common painting method that allows for efficient large-area painting while achieving a more uniform coating effect. Currently, various types of spraying equipment are available on the market, including electric sprayers and manual spray guns. Interior decoration encompasses room design, renovation, furniture arrangement, and various small decorative touches, focusing primarily on the interior construction of buildings. During interior decoration, wall spraying is often necessary, typically involving the application of latex paint. This application requires the use of spraying equipment.
[0003] When using spray painting equipment for interior wall decoration, the wall surface needs to be cleaned before spraying to remove dirt, grease, and other impurities, and kept dry. At the same time, a suitable paint should be selected and thoroughly stirred and mixed according to the instructions. During spraying, attention should be paid to techniques such as spraying distance, spraying angle, spraying amount, and spraying speed. For example, the spraying distance should not be too close or too far; the spraying angle should be perpendicular to the wall or slightly tilted; the spraying amount should be appropriate, neither too much nor too little; and the spraying speed should be kept stable, neither too fast nor too slow.
[0004] Chinese Patent Publication (Announcement) No. CN113585674A discloses a wall spraying device for decoration and renovation, including a first connecting frame, a base frame, a material guide, a paint tank, a protective cover, and a paint pump. The first connecting frame has second connecting frames on both the left and right sides of its bottom end. The bottom ends of the two sets of second connecting frames are respectively connected to the left and right sides of the top of the base frame. Universal wheels are provided on the left front, left rear, right front, and right rear sides of the bottom of the base frame. An electric slide rail is provided on the left end of the left second connecting frame, and a sliding seat is slidably mounted on the electric slide rail. A first mounting frame is provided on the left end of the sliding seat. The material guide is mounted on the first mounting frame, and multiple spray nozzles are connected to the left output end of the material guide. The bottom end of the paint tank is connected to the right side of the top of the base frame. The paint tank has a chamber inside, and a filling device is connected to the upper left side of the chamber. This device can effectively improve spraying efficiency and quality, reduce labor intensity, and mitigate limitations.
[0005] Nowadays, when spraying latex paint, a pipe is installed on one side of the spraying device's output port, and a nozzle is installed at one end of the pipe. The worker holds the nozzle and sprays the wall. During the spraying process, the worker needs to hold the nozzle continuously, which is tiring. Spraying also requires a high level of experience from the worker, and it is easy to spray unevenly. When spraying high parts of the wall, the worker needs to use ladders or other tools, which is inconvenient for spraying at heights. Summary of the Invention

[0030] S3. The air pump starts, and the latex paint is delivered to the nozzle through the delivery pipe for spraying.
[0031] The present invention has at least the following beneficial effects:
[0032] (1) This solution: By setting the first moving component and the second moving component, the installation rod is vertically fixed, thereby fixing the lifting component and the spraying component to one side of the wall. By setting the lifting component, it can move up and down on the outer wall of the installation rod, thereby driving the spraying component to move up and down. When spraying the wall, it can support the spraying component, so that the workers do not have to hold the spray gun all the time. By setting the spraying component that can move up and down, it is easier to spray the high parts of the wall. When spraying the wall, after the spraying component has sprayed a part of the wall, the workers can push the middle of the installation rod to move the spraying component horizontally, so that the spraying component can continue to spray other parts of the wall, making it easier to spray evenly.
[0033] (2) This solution: The third motor starts and drives the lead screw to rotate, which can drive the first moving part to move up and down, thereby driving the spray frame to move up and down, so that the spray frame can be moved up and down on one side of the mounting frame to adjust its position, avoiding the spray frame not being sprayed, and making the spraying more thorough.
[0034] (3) This solution: The second spring supports the roller to press against the wall surface, so that the latex paint is applied more evenly to the wall surface while spraying, making the latex paint spraying more even. In addition, by setting up a spray frame to block the spread of latex paint during spraying, the spread of latex paint can be reduced, and the latex paint can be prevented from splashing onto the workers.
[0035] (4) This solution uses a fan to draw air through the ventilation slots when the fan is turned on. The fan can then pre-dry the latex paint on the wall, which can accelerate the drying of the latex paint and prevent the latex paint from dripping down. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] Please see Figures 1-9This invention provides an indoor wall painting device and method, comprising: a mounting rod 1, with a first telescopic mechanism and a second telescopic mechanism for extension and retraction respectively provided at the top and bottom; a first moving component; the first moving component is installed at one end of the first telescopic mechanism and is attached to the indoor ceiling by a top moving plate 204 and a first ball bearing 205, thereby fixing the mounting rod 1 from one end of the ceiling; a second moving component; the second moving component is installed at one end of the second telescopic mechanism and is attached to the indoor floor by a bottom second ball bearing 209, thereby fixing the mounting rod 1 from one end of the floor; and a lifting component, installed on one side of the outer wall of the mounting rod 1 and sliding on the outer wall of the mounting rod 1 by a sliding frame 503 and a pulley 504 on one side. The spraying assembly is installed on one side of the lifting assembly. The spraying assembly slides on the lifting assembly side via a first moving part 601 and a second moving part 6011, and sprays the interior wall surface through an internal nozzle 409. A first telescopic mechanism and a second telescopic mechanism are provided to extend and retract the first and second moving parts, fixing them to the ceiling and floor respectively. The first and second moving parts also serve to vertically fix the mounting rod 1, thus securing the lifting assembly and the spraying assembly to one side of the wall. The lifting assembly can move up and down on the outer wall of the mounting rod 1, thus moving the spraying assembly up and down. The lifting assembly also allows the spraying assembly to adjust its position by moving up and down on one side of the lifting assembly, making spraying more convenient. When spraying the wall, the spraying assembly can be supported, freeing the worker from constantly holding the spray gun. Furthermore, the vertically movable spraying assembly makes it easier to spray higher areas of the wall.
[0050] In some embodiments, see Figure 1 , Figure 4 , Figure 5The mounting rod 1 has mounting grooves 101 at both ends. The first telescopic mechanism includes a first electric push rod 102 and a first sliding cylinder 103. The first electric push rod 102 is fixedly installed at one end of the groove wall of the mounting groove 101 at the top of the mounting rod 1, and the first sliding cylinder 103 is slidably installed at the top of the outer wall of the mounting rod 1. The second telescopic mechanism includes a second electric push rod 104 and a second sliding cylinder 105. The second electric push rod 104 is fixedly installed at one end of the groove wall of the mounting groove 101 at the bottom of the mounting rod 1, and the second sliding cylinder 105 is slidably installed at the bottom of the outer wall of the mounting rod 1. The outer walls of the mounting rod 1, the first sliding cylinder 103, and the second sliding cylinder 105 have a plurality of first sliding grooves 106. The positions of the first sliding grooves 106 on the mounting rod 1, the first sliding cylinder 103, and the second sliding cylinder 105 are corresponding. The moving component includes a movable frame 2, several second slide grooves 201, several first springs 202, and a limiting plate 203. The movable frame 2 is fixedly installed at one end of the output end of the first electric push rod 102. One end of the first sliding cylinder 103 is fixedly installed at the bottom end of the movable frame 2. Several second slide grooves 201 are opened at the top end of the movable frame 2. Several first springs 202 are fixedly installed at one end of the groove wall of the corresponding second slide groove 201. The limiting plate 203 is fixedly installed at one end of the corresponding first spring 202 and is slidably installed on the groove wall of the corresponding second slide groove 201. The moving plate 204 is fixedly installed at one end of the corresponding limiting plate 203. Several first balls 205 are movably installed at the top end of the corresponding moving plate 204. The second moving component includes a mounting base 206, several connecting rods 207, and a moving column 208.
[0051] Mounting base 206 is fixedly mounted on one end of the output end of the second electric push rod 104. Second sliding cylinder 105 is fixedly mounted on one end of mounting base 206. Several connecting rods 207 are fixedly mounted on the bottom end of mounting base 206. Moving column 208 is fixedly mounted on one end of the corresponding connecting rod 207. Second ball bearing 209 is movably mounted on the bottom end of the corresponding moving column 208. The activation of the first electric push rod 102 and the second electric push rod 104 drives the mounting base 206 and the moving frame 2 at the output ends of the first and second electric push rods 102 and 104 to extend. The first ball bearing 205 on the movable frame 2 is supported on the ceiling. The first spring 202 supports the movable plate 204 and the first ball bearing 205 to press against the ceiling. By setting several movable plates 204, each movable plate 204 can slide up and down independently, which can make the movable plate 204 and the first ball bearing 205 move more smoothly on the ceiling. The mounting base 206 and several connecting rods 207 are placed on the floor. By setting the movable column 208 and the second ball bearing 209 at the bottom of the connecting rod 207, the second movable component can move on the floor.
[0052] In this example, when spraying the wall, after the spraying component has finished spraying a part of the wall, the worker can push the middle of the mounting rod 1 to move the spraying component laterally, so that the spraying component can continue to spray other parts of the wall, making it easier to spray evenly.
[0053] In some embodiments, see Figure 7 The lifting assembly includes a mounting frame 5, a connecting plate 501, several limiting grooves 502, a first mounting plate 505, a second mounting plate 506, a third motor 507, a lead screw 508, and a limiting rod 509. The connecting plate 501 is fixedly installed on the top of the mounting frame 5. Several limiting grooves 502 are all opened on one side of the connecting plate 501. Several sliding frames 503 are fixedly installed on one side of the connecting plate 501. Pulleys 504 are rotatably installed on the inner wall of the corresponding sliding frame 503. The pulleys 504 extend to the outside of one side of the corresponding sliding frame 503. The pulleys 504 are slidably installed on the first sliding groove 106 of the outer wall of the corresponding mounting rod 1, the first sliding cylinder 103, and the second sliding cylinder 105. The first mounting plate 505 is fixedly installed on the top of both sides of the mounting frame 5.
[0054] The second mounting plate 506 is fixedly installed on the bottom ends of both sides of the mounting frame 5. The third motor 507 is fixedly installed on the bottom end of one of the second mounting plates 506, with one end of the output end of the third motor 507 extending to the top end of the corresponding second mounting plate 506. The lead screw 508 is fixedly installed on one end of the output end of the third motor 507, with one end of the lead screw 508 rotatably installed on the bottom end of the corresponding first mounting plate 505. The limiting rod 509 is fixedly installed on the top end of the other second mounting plate 506, with one end of the limiting rod 509 fixedly installed on the bottom end of the corresponding first mounting plate 505. A first fixing plate 3 is fixedly installed on one side of the moving frame 2, and a first motor is fixedly installed on the top end of the first fixing plate 3. The first motor 301 has a first turntable 302 fixedly installed at one end of its output end. A second fixing plate 303 is fixedly installed on the outer wall of the mounting base 206. A second motor 304 is fixedly installed at the top of the second fixing plate 303. A second turntable 305 is fixedly installed at one end of its output end. Connecting ropes 306 are fixedly installed on the outer walls of both the first turntable 302 and the second turntable 305. One end of the connecting rope 306 installed on the first turntable 302 is fixedly installed on one end of the connecting plate 501 at the top of the mounting frame 5. One end of the connecting rope 306 installed on the second turntable 305 is fixedly installed on one end of the connecting plate 501 at the bottom of the mounting frame 5.
[0055] The mounting frame 5 and the connecting plate 501 form a rectangular frame. The mounting frame 5 and the connecting plate 501 achieve lifting and lowering functions through the cooperation of the first motor 301 and the second motor 304. Specifically, when the mounting frame 5 and the connecting plate 501 need to be raised, the first motor 301 starts and drives the first turntable 302 to rotate. The first turntable 302 tightens the connecting rope 306, and the connecting rope 306 pulls the mounting frame 5 and the connecting plate 501 upward. At the same time, the second motor 304 starts and drives the second turntable 305 to rotate. The second turntable 305 releases the connecting rope 306 at the bottom, allowing the mounting frame 5 and the connecting plate 501 to move upward smoothly. When the mounting frame 5 and the connecting plate 501 need to be moved downward, the first motor 301 and the second motor 304 operate in the opposite manner.
[0056] In this example, the third motor 507 starts and drives the lead screw 508 to rotate, which can drive the first moving part 601 to move up and down, thereby driving the spray frame 6 to move up and down. This makes it easier for the spray frame 6 to move up and down on one side of the mounting bracket 5 to adjust its position, avoiding the spray frame 6 not being sprayed properly, and allowing for more thorough spraying.
[0057] In this example, the middle part of the mounting rod 1 is U-shaped, reserving space for the mounting housing 402. When the lifting assembly moves to the U-shaped position of the middle part of the mounting rod 1, the limiting groove 502 on one side of the connecting plate 501 is engaged in the limiting block 401, allowing the lifting assembly to move smoothly. When it moves out of the U-shaped position of the middle part of the mounting rod 1, the pulley 504 is engaged in the first sliding groove 106 again.
[0058] In some embodiments, see Figure 8 The spraying assembly includes a spraying frame 6, a through hole, a baffle 602, a third mounting plate 603, several fans 604, several ventilation slots 605, and a sliding plate 606. A first moving part 601 and a second moving part 6011 are fixedly installed on one side of the spraying frame 6. One end of the first moving part 601 has a threaded hole, and the first moving part 601 is movably installed on the outer wall of the lead screw 508 through the threaded hole. One end of the second moving part 6011 has a sliding hole, and the second moving part 6011 is slidably installed on the outer wall of the limiting rod 509 through the sliding hole. The through hole... A baffle 602 is fixedly installed on one side of the spray frame 6, located at the bottom of the through hole. A third mounting plate 603 is fixedly installed on both sides of the inner wall of the spray frame 6. Several fans 604 are fixedly installed on one side of the third mounting plate 603. Several ventilation slots 605 are opened on both sides of the spray frame 6. Several sliding plates 606 are fixedly installed on one side of the spray frame 6 and slidably installed on one side of the mounting bracket 5. The nozzle 409 is fixedly installed on the inner wall of the through hole. A fixing bracket 4 is fixedly installed in the middle of the outer wall of the mounting rod 1. The fixing bracket 4 is U-shaped.
[0059] Each of the fixed frames 4 is fixedly installed with a limit block 401, which slides on the wall of the corresponding limit groove 502. A housing 402 is fixedly installed on one side of the fixed frame 4. A storage cylinder 403 is fixedly installed on the top of the inner wall of the housing 402. A feeding frame is fixedly installed on the top of one side of the housing 402. One end of the feeding frame extends into the inside of the housing 402 and is connected to the storage cylinder 403. A feed cylinder 404 is installed on the other end of the feeding frame.
