[0002] The paint spraying equipment is special mechanical equipment capable of efficiently and uniformly coating paint on the surface of an object, and the paint is atomized into fine particles by air power or mechanical force and then uniformly sprayed on the surface of a workpiece to realize the protection and decoration of the target object. When the spraying equipment is working, a large amount of gas-liquid mixture is pushed at high speed, so that a large amount of gas pressure cannot be released, and part of the gas-liquid mixture adheres to the inner wall of the spray hole when passing through the spray hole, which causes the filter to be blocked and the effective flow to be significantly reduced.

Wherein, the inner wall of the through hole of the rotary scraper slides along the surface thread marks of the fixed shaft under the pushing of the fixed shaft, and the rotary scraper rotates at the outer wall of the filter screen when the rotary scraper slides on the surface of the fixed shaft due to the rotatable connection of the rotary scraper to the outer wall of the filter screen, thereby scraping off the dirt adhered to the surface of the filter screen while rotating. When the air inlet hole and the liquid inlet hole stop supplying, no gas-liquid enters the inside of the spray gun shell, the connecting ball is driven out of the clamping groove by the elastic force of the spring II, the spring fixedly connected between the clamping buckle and the compression rod is subjected to the elastic force and rebounds, thereby driving the clamping buckle to rebound and reset, the sliding block is pulled to the H space by the elasticity of the spring I, part of the gas-liquid mixture in the Z space is sucked into the H space, the residual gas-liquid mixture in the H space enters the air inlet hole into the air inlet tank, the air inlet tank completes the compression and release of air pressure, the H position space increases and the air pressure decreases, the sliding block is pulled to the H space by the spring I, which causes the Z position space to increase and the air pressure to decrease, thereby adsorbing the external air, the external air enters the Z space through the filter screen inner hole, and the residual substances on the inner wall of the filter screen inner hole are removed by air adsorption.

[0009] Preferably, the pull rod assembly comprises a clamping buckle slidingly connected to the inner wall of the spray gun shell, a compression rod fixedly connected to the front surface of the clamping buckle, a spring fixedly connected to the outer wall of the compression rod, a spring II fixedly connected to the side wall of the clamping buckle, a connecting ball fixedly connected to the end of the spring II away from the clamping buckle, the top of the connecting ball in contact with the inner wall of the spray gun shell, a clamping groove fixedly connected to the outer wall of the spray gun shell, an air inlet tank fixedly connected to the inner wall of the spray gun shell, the outer wall of the compression rod slidingly connected to the inner wall of the air inlet tank, and an air inlet formed in the outer surface of the air inlet tank. The plate buckle slides under the pulling of the staff, and the plate buckle exerts a pulling force on the compression rod when sliding, so that the compression rod is stretched, spring two and the connecting ball follow the sliding, when the connecting ball slides to the clamping groove, spring two and the connecting ball enter the clamping groove to limit the plate buckle.

[0010] Preferably, the compression assembly comprises a compression box fixedly connected to the bottom of the air inlet box, a baffle fixedly connected inside the compression box, a push rod fixedly connected to the left surface of the baffle, a plate buckle fixedly connected to the side of the push rod away from the baffle, a fixed rod fixedly connected to the bottom surface of the baffle, and a U-shaped channel pipe fixedly connected to the inner wall of the compression box. When the plate buckle is pulled by the pulling force, the push rod slides to the left with the plate buckle, and the push rod drives the baffle to move synchronously, at this time, the air pressure in the compression box is compressed, when the staff stops pressing the plate buckle, the plate buckle drives the push rod to pull back by the elasticity of the fixed spring, so that the push rod pushes the baffle to the right, and the air pressure in the compression box is released, when the air pressure is released, the baffle pushes the residual liquid into the U-shaped channel pipe, and the residual liquid enters the storage box through the U-shaped channel pipe.

[0011] Preferably, the ventilation assembly comprises a connecting button slidingly connected to the bottom of the compression box, spring four fixedly connected to the bottom of the connecting button, a blocking block fixedly connected inside the spring four, a storage box fixedly connected to the bottom of the compression box, and a ventilation pipe fixedly connected inside the storage box. The connecting button is pressed downward in the collision of the fixed rod, so that the connecting button exerts a pressure on spring four, spring four is compressed under the pressure to exert a pressure on the blocking block, and the blocking block is popped up by spring four, so that the ventilation pipe is dredged to release the air pressure.

[0012] Preferably, the push rod assembly comprises a telescopic plate slidingly connected to the inner wall of the storage box, and spring three fixedly connected to the top of the telescopic plate. The liquid continuously accumulates to exert a pushing force on the telescopic plate, and the telescopic plate floats upward along with the accumulation of the liquid, when the telescopic plate reaches the clamping groove, the internal spring three is popped out to complete the limiting.

[0013] The present application has the following advantages: (1) This invention addresses the problem that the entry of a gas-liquid mixture can cause residual liquid to adhere to the edge of the spray gun nozzle, affecting subsequent continuous working efficiency. When the operator pulls the plate buckle, the compression rod slidably connected to the plate buckle is stretched. At this time, the second spring and the connecting ball slide along the inner wall of the spray gun housing with the plate buckle. When the connecting ball enters the slot, it completes the limiting of the plate buckle, achieving the effect of saving effort. A rotating mechanism is provided inside the spray gun housing. Due to the presence of the pushing component, when the gas-liquid mixture enters, it will push the sliding block to slide forward in the outer rod. Since the inner wall of the sliding block is fixedly connected to the first spring, when the sliding block moves forward... When the sliding block slides forward, it is pulled by spring one and reaches a certain distance to complete the limit stop. When the sliding block slides forward, the fixed shaft fixedly connected to the outer wall of the sliding block is pushed. At this time, since the fixed shaft is slidably connected to the inner wall of the through hole of the rotating scraper, the inner wall of the through hole of the rotating scraper slides along the surface thread of the fixed shaft under the push of the fixed shaft. Since the rotating scraper is rotatably connected to the outer wall of the filter screen, it rotates on the outer wall of the filter screen when the rotating scraper slides on the surface of the fixed shaft, thereby scraping off the dirt adhering to the surface of the filter screen while rotating. Through the application of the above components, the residual liquid on the inner wall of the spray gun nozzle is effectively removed.

[0014] (2) When the operator stops using the device, the air inlet and liquid inlet stop supplying fluid, and no air or liquid enters the spray gun housing. The spring force of spring two drives the connecting ball out of the slot. At this time, the spring fixed between the plate buckle and the compression rod is subjected to spring force and rebounds, causing the plate buckle to return to its original position. Figure 2 As shown, the elasticity of spring one drives the sliding block to pull towards space H. Part of the gas-liquid mixture in space Z is drawn into space H. The remaining gas-liquid mixture in space H enters the air intake box through the air inlet. The air intake box completes the compression and release of air pressure. As space H increases, air pressure decreases. At this time, spring one pulls the sliding block towards space H, causing space Z to increase and air pressure to decrease, thus adsorbing external air. At this time, external air enters space Z through the inner hole of the filter screen. The air adsorption removes the residue on the inner wall of the filter screen, thereby effectively preventing the liquid in the inner hole of the filter screen from drying out and affecting subsequent work.

[0015] (3) The present invention utilizes the characteristics of air pressure backflow. The residual gas-liquid mixture will enter the air inlet box through the air inlet and then enter the compression box. The compression box has a sliding baffle. When the plate buckle is pulled by the tension, the push rod slides to the left with the plate buckle. At the same time, the push rod drives the baffle to move synchronously. At this time, the air pressure in the compression box is compressed. When the staff stops applying pressure to the plate buckle, the plate buckle uses its own spring elasticity to drive the push rod back, thereby pushing the baffle to the right and releasing the air pressure in the compression box.

[0016] (4) This invention utilizes the characteristic of the air pressure inside the compression box being released. When the air pressure is released, the baffle pushes the residual liquid into the U-shaped channel tube, and the residual liquid enters the storage box through the U-shaped channel tube. As the liquid accumulates over time, it exerts a pushing force on the telescopic plate. Since the telescopic plate floats on the liquid, it floats upward with the accumulation of liquid. When the telescopic plate reaches the slot, it pops out to complete the limit, and at the same time reminds the staff to discover and clean the storage box in time. At this time, the staff only needs to press the telescopic plate, and the telescopic plate will fall back to its original position. When the baffle passes the connecting button, the fixed rod fixedly connected to the baffle applies pressure to the connecting button, forcing the connecting button to apply pressure to the spring four. The spring four squeezes the air block, causing the air block to pop up, thereby clearing the vent pipe. At this time, the residual gas flows out through the vent pipe, completing the release of air pressure. Attached Figure Description

[0020] 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.

[0021] Example 1, please refer to Figure 1 - Figure 7 This invention relates to a spraying device for absorbing and conducting conductive coatings in aviation, comprising a spray gun housing 13, an air inlet 14 connected through to the bottom of the spray gun housing 13, and a liquid inlet 15 connected through to the outer wall of the spray gun housing 13, and further comprising: Rotating mechanism 1 is fixedly connected to the inner wall of the spray gun housing 13; Pull-pull mechanism 2 is fixedly connected to the inner wall of the spray gun housing 13; The ventilation mechanism 3 is fixedly connected to the bottom of the spray gun housing 13.

[0022] Before use, the staff first hold the spray gun housing 13 in their hands and open the air inlet 14 and liquid inlet 15. Then, the gas and liquid enter the interior of the spray gun housing 13, forcing the push component 11 to drive the cleaning component 12 to rotate.

[0023] Rotating mechanism 1 includes: Push component 11 is fixedly connected inside the spray gun housing 13; Cleaning component 12 is rotatably connected to the top of pushing component 11; Before use, the air inlet 14 and liquid inlet 15 are opened, and then the air and liquid enter the spray gun housing 13, forcing the push assembly 11 to drive the cleaning assembly 12 to rotate.

[0024] The pull-pull mechanism 2 includes: Pull rod assembly 21 is fixedly connected to the outer wall of spray gun housing 13; Push rod assembly 22, which is disposed inside the ventilation mechanism 3; During the process, the operator applies a pulling force to the lever assembly 21, which slides against the outer wall of the spray gun housing 13. As the operator stops pulling the lever assembly 21, the gas-liquid mixture inside the spray gun housing 13 enters the ventilation mechanism 3 through the pull-push mechanism 2.

[0025] The ventilation mechanism 3 includes: Compression component 31 is fixedly connected to the bottom of pull rod assembly 21. Ventilation assembly 32 is fixedly connected to the bottom of compression assembly 31; During the process, the staff applies a pulling force to the lever assembly 21. Under the push of the lever assembly 21, the internal volume of the compression assembly 31 gradually decreases. While the compression assembly 31 compresses the gas, it is released through the ventilation assembly 32.

[0026] Example 2, please refer to Figure 3 - Figure 10 The present invention is a spraying device for absorbing and conducting conductive coatings for aviation. Based on Example 1, the pushing component 11 includes an outer rod 111 fixedly connected to the inner wall of the spray gun housing 13, a sliding block 112 slidably connected to the inner wall of the outer rod 111, a spring 113 fixedly connected to the inner wall of the sliding block 112, and a fixed shaft 114 fixedly connected to the outer wall of the sliding block 112. When the outer rod 111 is pushed forward by the gas and liquid thrust, it causes the sliding block 112 to slide forward on the inner wall of the outer rod 111. At this time, the sliding block 112 generates a pulling force on the spring 113, which causes the sliding block 112 to generate a thrust on the fixed shaft 114 and push it forward.

[0027] The cleaning assembly 12 includes a filter screen 122 fixedly connected to the inner wall of the spray gun housing 13, a rotating scraper 121 rotatably connected to the outer wall of the filter screen 122, a plurality of filter screen inner holes 123 opened on the outer wall of the filter screen 122, and the outer wall of the fixed shaft 114 slidably connected to the inner wall of the through hole of the rotating scraper 121. Under the push of the fixed shaft 114, the inner wall of the through hole of the rotating scraper 121 slides along the surface thread of the fixed shaft 114. The rotating scraper 121 scrapes off the residue on the surface of the filter screen 122 by rotating. The residue in the inner hole 123 of the filter screen is removed by the adsorption force generated by the pull rod assembly 21.

[0028] The pull rod assembly 21 includes a plate buckle 211 slidably connected to the inner wall of the spray gun housing 13. A compression rod 212 is fixedly connected to the front surface of the plate buckle 211. A spring is fixedly connected to the outer wall of the compression rod 212. A second spring 213 is fixedly connected to the side wall of the plate buckle 211. A connecting ball 214 is fixedly connected to the end of the second spring 213 away from the plate buckle 211. The top of the connecting ball 214 contacts the inner wall of the spray gun housing 13. A slot 215 is fixedly connected to the outer wall of the spray gun housing 13. An air inlet box 217 is fixedly connected to the inner wall of the spray gun housing 13. The outer wall of the compression rod 212 is slidably connected to the inner wall of the air inlet box 217. An air inlet 216 is opened on the outer surface of the air inlet box 217. The buckle 211 slides under the pull of the staff. While sliding, the buckle 211 applies a pulling force to the compression rod 212, so that when the compression rod 212 is stretched, the spring 213 and the connecting ball 214 slide along with it. When the connecting ball 214 slides to the slot 215, the spring 213 and the connecting ball 214 enter the slot 215 to complete the limiting of the buckle 211.

[0029] The bottom of the air intake box 217 is fixedly connected to the compression box 315. The compression assembly 31 includes a baffle 312 fixedly connected inside the compression box 315. A push rod 311 is fixedly connected to the left surface of the baffle 312. A plate buckle 211 is fixedly connected to the side of the push rod 311 away from the baffle 312. A fixing rod 313 is fixedly connected to the bottom surface of the baffle 312. A U-shaped channel tube 314 is fixedly connected to the inner wall of the compression box 315. The push rod 311 slides under the pull of the plate buckle 211, which causes the push rod 311 to exert a pulling force on the baffle 312. As the baffle 312 slides, the fixing rod 313 fixedly connected to the bottom surface of the baffle 312 also slides. While the baffle 312 slides, it discharges the gas-liquid mixture through the U-shaped channel pipe 314.

[0030] The ventilation assembly 32 includes a connection button 321 that is slidably connected to the bottom of the compression box 315. A spring 322 is fixedly connected to the bottom of the connection button 321. An air-blocking block 323 is fixedly connected inside the spring 322. A storage box 325 is fixedly connected to the bottom of the compression box 315. A ventilation pipe 324 is fixedly connected inside the storage box 325. In this process, the connecting button 321 is pressed downward upon impact with the fixing rod 313, causing the connecting button 321 to exert pressure on the spring 322. The spring 322 is compressed under pressure, exerting pressure on the air block 323. The air block 323 is then lifted up by the spring 322, thereby clearing the air pipe 324 and releasing the air pressure.

[0031] The push rod assembly 22 includes a telescopic plate 221 that is slidably connected to the inner wall of the storage box 325, and a spring 222 is fixedly connected inside the telescopic plate 221; As the liquid accumulates over time, it exerts a pushing force on the telescopic plate 221. Since the telescopic plate 221 floats on the liquid, it floats upward with the accumulation of liquid. When the telescopic plate 221 reaches the slot, the internal spring 222 pops out to complete the limit stop, and at the same time reminds the staff to discover and clean the storage box 325 in time. At this time, the staff only needs to press the telescopic plate 221, and the telescopic plate 221 will fall back to its original position.

[0032] One specific application of this embodiment is as follows: Before use, the staff first holds the spray gun housing 13 in their hand and opens the air inlet 14 and the liquid inlet 15. Then, the gas and liquid enter the interior of the spray gun housing 13, forcing the pushing component 11 to push the cleaning component 12 to rotate.

[0033] To address the issue that the entry of a gas-liquid mixture can cause residual liquid to adhere to the edges of the spray gun nozzle, affecting subsequent continuous working efficiency, the following measures are implemented: When the operator pulls the latch 211, the compression rod 212, which is slidably connected to the latch 211, is stretched. At this time, the spring 213 and the connecting ball 214 slide along the inner wall of the spray gun housing 13 with the latch 211. When the connecting ball 214 enters the slot 215, it simultaneously limits the latch 211, achieving a labor-saving effect. Since the spray gun housing 13 is equipped with a rotating mechanism 1, the presence of the pushing component 11 causes the sliding block 112 to slide forward within the outer rod 111 when the gas-liquid mixture enters. Because the inner wall of the sliding block 112 is fixedly connected to the spring 113, the sliding block 112... When sliding forward, it is pulled by spring 113 and reaches a certain distance to complete the limit. When the sliding block 112 slides forward, the fixed shaft 114 fixedly connected to the outer wall of the sliding block 112 is pushed. At this time, since the fixed shaft 114 is slidably connected to the inner wall of the through hole of the rotating scraper 121, the inner wall of the through hole of the rotating scraper 121 slides along the surface thread of the fixed shaft 114 under the push of the fixed shaft 114. Since the rotating scraper 121 is rotatably connected to the outer wall of the filter screen 122, when the rotating scraper 121 slides on the surface of the fixed shaft 114, it rotates on the outer wall of the filter screen 122, thereby scraping off the dirt adhering to the surface of the filter screen 122 while rotating. Through the application of the above components, the residual liquid on the inner wall of the spray gun nozzle is effectively removed.

[0034] Using the aforementioned push-pull mechanism 2, when the operator stops using the device, the air inlet 14 and liquid inlet 15 stop supplying fluid, and no air or liquid enters the spray gun housing 13. The spring force of spring 213 causes the connecting ball 214 to exit the slot 215. At this time, the spring fixed between the plate buckle 211 and the compression rod 212 is subjected to spring force and rebounds, causing the plate buckle 211 to return to its original position. Figure 2 As shown, the elasticity of spring 113 drives the sliding block 112 to pull towards space H. Part of the gas-liquid mixture in space Z is drawn into space H. The remaining gas-liquid mixture in space H enters the air intake box 217 through the air inlet 216. The air intake box 217 completes the compression and release of air pressure. The space in position H increases and the air pressure decreases. At this time, spring 113 pulls the sliding block 112 towards space H, causing the space in position Z to increase and the air pressure to decrease, thus adsorbing external air. At this time, external air enters space Z through the inner hole 123 of the filter screen. The air adsorption removes the residue on the inner wall of the inner hole 123 of the filter screen, thereby effectively preventing the liquid in the inner hole 123 of the filter screen from drying out and affecting subsequent work.

[0035] Utilizing the aforementioned air pressure reflux characteristics, the residual gas-liquid mixture will enter the air intake box 217 through the air inlet 216, and then enter the compression box 315 through the air intake box 217. Inside the compression box 315, a sliding baffle 312 is connected. When the plate buckle 211 is pulled by a tension force, the push rod 311 slides to the left along with the plate buckle 211. At the same time, the push rod 311 drives the baffle 312 to move synchronously, thus compressing the air pressure in the compression box 315. When the operator stops applying pressure to the plate buckle 211, the plate buckle 211 uses its own spring elasticity to drive the push rod 311 to pull back, thereby pushing the baffle 312 to the right and releasing the air pressure in the compression box 315.

[0036] Taking advantage of the release of internal air pressure in the aforementioned compression box 315, when the air pressure is released, the baffle 312 pushes the residual liquid into the U-shaped channel tube 314. The residual liquid then enters the storage box 325 through the U-shaped channel tube 314. As the liquid accumulates over time, it exerts a pushing force on the telescopic plate 221. Since the telescopic plate 221 floats on the liquid, it floats upward with the accumulation of liquid. When the telescopic plate 221 reaches the slot, it pops out to complete the limit stop, and at the same time reminds the staff to discover and clean the storage box 325 in time. At this time, the staff only needs to press the telescopic plate 221, and the telescopic plate 221 will fall back to its original position.

[0037] When the baffle 312 passes the connecting button 321, the fixing rod 313, which is fixedly connected to the baffle 312, applies pressure to the connecting button 321, forcing the connecting button 321 to apply pressure to the spring 322. The spring 322 squeezes the air block 323, causing the air block 323 to bounce up, thereby clearing the vent pipe 324. At this time, the residual gas flows out through the vent pipe 324, completing the release of air pressure.
