Description

Technical Field

[0001] This invention relates to the field of paint nozzle cleaning technology, and in particular to a paint nozzle cleaning structure for an eggshell gloss art paint dispensing device. Background Technology

[0002] Eggshell glossy art paint is a wall decoration coating with a unique texture and gloss. It is named for its eggshell-like texture and gloss. It features high color saturation and strong color retention. In addition, it is washable, stain-resistant, mildew-proof, algae-resistant, and antibacterial, making it easy to maintain and clean.

[0003] Currently, there are two types of paint dispensing equipment for eggshell glossy art paint: roller-type and spray gun-type. For roller-type paint dispensing equipment, a cleaning structure for the nozzle is disclosed in Chinese Patent Publication No. CN220295017U, which provides a nozzle cleaning device and a paint dispensing device. While this device can solve the problems of liquid accumulation at the nozzle affecting the accuracy of mixing and the solidification of the accumulated liquid causing clogging, it is primarily designed for roller-type paint dispensing equipment and lacks a cleaning structure specifically for spray gun-type nozzles. This means that cleaning the nozzles of existing spray gun-type paint dispensing equipment still largely relies on manual labor, with only a small portion using [other methods]. Cleaning using reverse rinsing involves several steps. Manual cleaning of the paint nozzle requires complete disassembly of the entire nozzle structure, immersion in a special solvent, careful unclogging of the nozzle orifice with a needle, removal of solidified residue from the spray cap's vortex chamber with a brush, and finally wiping it clean and reassembling. This process is time-consuming, labor-intensive, and inefficient, involving frequent disassembly and reassembly of vulnerable parts. While reverse rinsing offers better cleaning, it may still leave stubborn residues. Furthermore, it necessitates the addition of a switching valve and a second flow channel, complicating the cleaning process and increasing costs. Therefore, this application provides a nozzle cleaning structure for an eggshell art paint dispensing device to meet these requirements. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a cleaning structure for the nozzle of an eggshell-shaped art paint dispensing device. This solves the problems of existing spray gun-type paint dispensing devices where cleaning the nozzle relies on manual labor, which is time-consuming, labor-intensive, and inefficient. Frequent disassembly can also damage parts. Furthermore, reverse rinsing cleaning is complex and may still leave residues, requiring additional equipment and increasing costs.

The lower groove is provided on the front side of the lower end of the frame, the upper groove is provided on the front side of the upper end of the frame, the rectangular groove is provided in the middle of the rear end of the frame, and the reinforcing bolt is provided on the lower end of the inner side of the frame.

[0008] Preferably, the cleaning chamber includes a chamber body, a docking frame, an embedded groove, and an electrical connector. The docking frame is located in the middle of the front end of the chamber body, the embedded groove is located at the upper end of the chamber body, and the electrical connector is located on the upper right side of the outer end of the chamber body.

[0009] Preferably, the front hatch includes a front cover plate, a docking shell, a threaded groove, and reinforcing pins. The docking shell is provided in the middle of the front end of the front cover plate, and the threaded groove is provided in the middle of the front end of the docking shell. Reinforcing pins are provided on the left and right sides of the front end of the front cover plate.

[0010] Preferably, the sealing cup includes a sealing ring, a cylindrical cup, a threaded ring, a conical cup, and a nozzle insertion cavity. The upper end of the sealing ring is provided with a cylindrical cup, the lower end of the sealing ring is provided with a threaded ring, the inner side of the lower end of the threaded ring is provided with a conical cup, and the inner side of the upper end of the cylindrical cup is provided with a nozzle insertion cavity.

[0011] Preferably, the sealing circular plate includes a positioning plate, a sealing gasket, a central hole, and a positioning hole. The upper end of the positioning plate is provided with a sealing gasket, the middle part of the upper end of the sealing gasket is provided with a central hole, and the outer side of the central hole is provided with a positioning hole.

[0012] Preferably, the cleaning brush includes a rotating shaft, a brush sleeve, and a limiting block. The brush sleeve is provided at the middle of the outer end of the rotating shaft, and the limiting blocks are provided on the upper and lower sides of the brush sleeve.

[0013] Preferably, the support module, the clamping module, and the cleaning chamber are spliced ​​and assembled together and reinforced with bolts. The rear end height and lateral diameter of the clamping module are adapted to the front end height and lateral diameter of the cleaning chamber. The front end of the front cover penetrates the inner middle of the rear end of the clamping module and extends to the outer side. The front cover and the sealing cup are mutually sealed. The sealing bottom cylinder and the rear cover are mutually sealed. The contact ends of the placement cup, the filter cartridge, and the ultrasonic transducer are threadedly sealed.

[0014] A method for using the cleaning structure of the paint nozzle in an eggshell gloss art paint dispensing device includes the following steps: Step 1: First, before starting work, use the set support module and bolts to fix the device on the upper end of the operating table through the screw holes opened on the front and rear sides of the upper end of the support plate. Then, assemble the clamping module and the cleaning chamber and reinforce them with bolts. Step 2: When it is necessary to clean the residue on the outer end of the paint nozzle, the paint dispensing device can be placed on the clamping module. The handle and the material storage connection end of the paint dispensing device are limited and fixed by the lower and upper grooves set on the upper and lower sides of the front of the frame. At the same time as the limit is fixed, the paint nozzle of the paint dispensing device will penetrate the interior of the sealed cup into the cleaning chamber and continue to extend to the middle area of ​​the sealed bottom cylinder. Step 3: Next, turn on the servo motor installed in the middle of the lower end of the sealed bottom cylinder, so that it drives the driving wheel in the middle of the gear set to rotate. The driving wheel in the middle of the gear set and the driven wheels distributed in an outer ring are meshed together, which can drive the cleaning brush installed on the upper end of the driven wheel to start rotating synchronously. Together with the wiping head installed on the upper end of the driving wheel, it cleans the residual substances on the paint nozzle from the front and the side. Step 4: After the painting work is completed, when it is necessary to clean the inside of the paint nozzle, insert the paint dispensing device directly into the cup from the top, so that the paint dispensing head of the device extends into the inside of the filter cartridge. Then, connect it to the external ultrasonic generator through the electrical connector set at the outer end of the chamber, so that the mains power is converted into a high-frequency electrical signal, which drives the ultrasonic transducer installed inside the lower end of the filter cartridge to start working. Through the ultrasonic transducer, the ultrasonic cavitation effect is used inside the filter cartridge to generate countless tiny vacuum bubbles in the cleaning fluid. When these bubbles burst, they generate strong shock waves that act on the inner and outer surfaces of the paint nozzle and the vortex cavity of the spray cap, breaking and peeling off stubborn cement, cured paint, etc. Step 5: When it is necessary to clean the inside of the cleaning chamber, first open the valve connected to the bottom of the cleaning chamber to remove the cleaning fluid and impurities inside. If you want to clean it thoroughly, simply separate the placement cup and the sealed bottom cylinder from the cleaning chamber to complete the internal cleaning work. At the same time, since the entire mechanical structure is relatively simple, after cleaning, you only need to assemble and reinforce it to complete the reset, which is relatively convenient and quick.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the gripping module limits and holds the handle and material storage connection of the spray gun-type paint dispenser. At the same time, the paint nozzle of the spray gun-type paint dispenser tilts and penetrates the interior of the sealed cup into the cleaning chamber, and continues to extend to the middle area inside the sealed bottom cylinder. Then, the servo motor is turned on, driving the drive wheel in the middle of the gear set to rotate. The drive wheel in the middle of the gear set and the driven wheels distributed in a ring on the outside are meshed together, which drives the cleaning brush installed on the upper end of the driven wheel to rotate synchronously. Together with the wiping head installed on the upper end of the drive wheel, the residual substances on the paint nozzle are wiped clean from the front and side.

[0016] Through the designated placement cup, an operator holds a handheld spray gun-style paint dispenser, inserting its nozzle directly through the inside of the placement cup and extending it downwards into the filter cartridge. Then, via an electrical connector at the outer end of the chamber, it connects to an external ultrasonic generator, converting mains power into a high-frequency electrical signal. This signal drives the ultrasonic transducer installed inside the lower end of the filter cartridge. The transducer utilizes the cavitation effect of ultrasound inside the filter cartridge to generate countless tiny vacuum bubbles in the cleaning fluid. These bubbles, upon bursting, produce powerful shock waves that act on the inner and outer surfaces of the nozzle and within the vortex cavity of the spray cap, shattering and peeling away stubbornly adhered cement, cured paint, and other contaminants.

[0017] In summary, this invention eliminates the need to disassemble the paint nozzle. Instead, it simply limits the spray gun-type paint dispensing device, allowing the nozzle to extend into the interior of two automatic cleaning structures. The internal wiping and ultrasonic cleaning mechanisms of each structure then clean the inside and outer surface of the nozzle. Compared to traditional manual cleaning or backwashing, this method offers superior cleaning results, saves time, effort, and costs, and reduces the need for frequent nozzle disassembly, thus minimizing component damage and extending service life.

[0022] like Figures 1 to 15 As shown, an embodiment of the present invention provides a cleaning structure for the nozzle of an eggshell art paint dispensing device, including a support module 1, a holding module 2 at the upper end of the support module 1, a cleaning chamber 3 at the rear end of the holding module 2, a front cover 4 at the middle of the front end of the cleaning chamber 3, a sealing cup 5 at the inner side of the front end of the front cover 4, a placement cup 6 at the inner side of the upper end of the cleaning chamber 3, a rear cover 7 at the lower end of the rear end of the cleaning chamber 3, a sealing bottom cylinder 8 at the lower end of the rear cover 7, a filter cylinder 9 at the lower end of the placement cup 6, an ultrasonic transducer 10 at the inner side of the lower end of the filter cylinder 9, a servo motor 11 at the middle of the lower part of the sealing bottom cylinder 8, a sealing bottom plate 12 at the upper end of the servo motor 11, a gear set 13 at the inner side of the upper end of the sealing bottom plate 12, a sealing circular plate 14 at the upper end of the gear set 13, and cleaning brushes 15 distributed in a ring at the upper end of the sealing circular plate 14.

[0023] The support module 1, the clamping module 2, and the cleaning chamber 3 are assembled together and reinforced with bolts at the joints. The rear height and lateral diameter of the clamping module 2 are matched with the front height and lateral diameter of the cleaning chamber 3. The front end of the front cover 4 passes through the inner middle of the rear end of the clamping module 2 and extends to the outer side. The front cover 4 and the sealing cup 5 are threaded together and their contact ends are sealed. The lower end of the placement cup 6 is embedded in the inner side of the upper end of the cleaning chamber 3, and their contact ends are sealed and reinforced with bolts. The sealing bottom cylinder 8 and the rear cover 7 are sealed together. The contact ends of the placement cup 6, the filter cartridge 9, and the ultrasonic transducer 10 are threadedly sealed. The outer end of the filter cartridge 9 has four symmetrical arc-shaped slots, and the inner side of the four arc-shaped slots is provided with a filter membrane. The power contact area of ​​the ultrasonic transducer 10 is sealed. The power contact pipe of the ultrasonic transducer 10 is connected to the electrical connector 304. The sealing base cylinder 8 and the sealing base plate 12 are installed in a threaded connection manner. The transmission end of the servo motor 11 and the sealing base plate 12 are installed in a sleeve connection, and the contact end is reinforced by bolts. The gear set 13 consists of one driving wheel and eight driven wheels on the outside. The middle shaft of the driving wheel and the transmission end of the servo motor 11 are sleeved together. The upper end of the middle shaft of the driving wheel is equipped with a wiping head. The lower end of the middle shaft of the driven wheel extends into the annular groove on the inner side of the sealing base plate 12. The upper end of the middle shaft of the driven wheel passes through the annular groove on the inner side of the sealing circular plate 14 and continues to extend upwards to be sleeved together with the cleaning brush 15 and reinforced with screws.

[0024] The clamping module 2 limits and clamps the handle and storage connection end of the spray gun-type paint dispenser. At the same time, the paint nozzle of the spray gun-type paint dispenser tilts and penetrates the interior of the sealed cup 5 into the cleaning chamber 3, and continues to extend to the middle area inside the sealed bottom cylinder 8. Then, the servo motor 11 is turned on, driving the drive wheel in the middle of the gear set 13 to rotate. The drive wheel in the middle of the gear set 13 and the driven wheels distributed in an outer ring are meshed together, which can drive the cleaning brush 15 installed on the upper end of the driven wheel to start rotating synchronously. Together with the wiping head installed on the upper end of the drive wheel, the residual substances on the paint nozzle are wiped and cleaned from the front and side.

[0025] Through the placement cup 6, an operator holds a spray gun-type paint dispensing device, inserting its nozzle directly through the inside of the placement cup 6 and extending it downwards into the interior of the filter cartridge 9. Then, through the electrical connector 304 located at the outer end of the chamber 301, it connects to an external ultrasonic generator, thereby converting the mains power into a high-frequency electrical signal, driving the ultrasonic transducer 10 installed inside the lower end of the filter cartridge 9 to start working. Through the ultrasonic transducer 10, the ultrasonic cavitation effect inside the filter cartridge 9 is used to generate countless tiny vacuum bubbles in the cleaning fluid. When these bubbles burst, they generate strong shock waves that act on the inner and outer surfaces of the paint nozzle and the vortex cavity of the spray cap, breaking and peeling off stubborn cement, cured paint, etc.

[0026] like Figures 1 to 4 As shown, in this embodiment, the support module 1 includes a support plate 101, a trapezoidal base 102, a reinforcing hole 103, a counterweight 104, and a drain hole 105. The trapezoidal base 102 is provided in the middle of the upper end of the support plate 101. The four corners of the upper end of the trapezoidal base 102 are provided with reinforcing holes 103. The counterweight 104 is provided inside the trapezoidal base 102. The drain hole 105 is provided on the rear side of the upper end of the support plate 101. The clamping module 2 includes a frame 201, a lower groove 202, an upper groove 203, a rectangular groove 204, and a reinforcing bolt 205. The lower groove 202 is provided on the front side of the lower end of the frame 201. The upper groove 203 is provided on the front side of the upper end of the frame 201. The rectangular groove 204 is provided in the middle of the rear end of the frame 201. The reinforcing bolt 205 is provided on the lower end of the inner side of the frame 201.

[0027] The support plate 101 and the trapezoidal base 102 are integral structures. Four screw holes are symmetrically opened on the front and rear sides of the upper end of the support plate 101. Four reinforcing holes 103 are symmetrically opened. The distribution spacing of the reinforcing holes 103 is adapted to the distribution spacing of the reinforcing bolts 205. The counterweight 104 is embedded in the trapezoidal groove opened on the inner side of the trapezoidal base 102. The position of the drain hole 105 is vertically located at the position of the drain pipe connected to the lower end of the cabin 301. The frame 201 is an integral structure. The size of the lower groove 202 and the upper groove 203 is adapted to the handle diameter and material connection end diameter of the spray gun type paint dispensing equipment. The inner diameter of the rectangular groove 204 is adapted to the outer diameter of the docking shell 402. Four reinforcing bolts 205 are symmetrically distributed.

[0028] A bottom support structure is formed by the support plate 101 and the trapezoidal base 102, which is fixed to the upper side of the spray painting workbench. Then, the frame 201 is fixed to the upper end of the bottom support structure by the reinforcing bolts 205 and the reinforcing holes 103 to form a bracket. With the lower groove 202 and the upper groove 203, the spray gun type paint dispensing equipment can be placed when not in use. At the same time, the design of the rectangular groove 204 allows the cleaning chamber 3 to be installed on the back of the frame 201, and the splicing end is reinforced with bolts. When the spray gun type paint dispensing equipment is placed, the front paint nozzle will extend into the cleaning chamber 3 to achieve automatic cleaning.

[0029] like Figures 1 to 5 As shown, in this embodiment, the cleaning chamber 3 includes a chamber body 301, a docking frame 302, an inner groove 303, and an electrical connector 304. The docking frame 302 is provided in the middle of the front end of the chamber body 301, the inner groove 303 is provided at the upper end of the chamber body 301, and the electrical connector 304 is provided on the upper right side of the outer end of the chamber body 301.

[0030] The cabin 301 and the docking frame 302 are integrated into one structure. At the same time, the outer diameter of the docking frame 302 and the inner diameter of the rear end of the docking shell 402 in the front cover 4 are compatible with each other, and the contact ends of the two are sealed. The embedded groove 303 is sealed by the top sealing plate. The inner side of the electrical connector 304 can be used to pass through the connecting wires to supply power to the ultrasonic transducer 10 installed inside the cabin 301.

[0031] The chamber 301 allows cleaning fluid to be injected inside. Since the interior of the chamber 301 is a single cavity, and the internal cavities of the sealed bottom cylinder 8 and the filter cartridge 9 are interconnected with the cavity opened on the inner side of the chamber 301, they can share the same cleaning fluid during cleaning. In addition, since the bottom of the chamber 301 is designed to be inclined, the impurities removed from the cleaning fluid can naturally settle at the bottom of the inclined area, making subsequent sewage discharge more convenient.

[0032] like Figures 1 to 7 As shown, in this embodiment, the front cover 4 includes a front cover plate 401, a docking shell 402, a threaded groove 403, and a reinforcing pin 404. The docking shell 402 is provided in the middle of the front end of the front cover plate 401, and the threaded groove 403 is provided in the middle of the front end of the docking shell 402. The reinforcing pins 404 are provided on the left and right sides of the front end of the front cover plate 401. The sealing cup 5 includes a sealing ring 501, a cylindrical cup 502, a threaded ring 503, a conical cup 504, and a nozzle insertion cavity 505. The upper end of the sealing ring 501 is provided with a cylindrical cup 502, the lower end of the sealing ring 501 is provided with a threaded ring 503, the inner side of the lower end of the threaded ring 503 is provided with a conical cup 504, and the inner side of the upper end of the cylindrical cup 502 is provided with a nozzle insertion cavity 505.

[0033] The front cover plate 401 and the mating shell 402 are integrated into one structure. The outer side of the threaded groove 403 has a groove for installing the seal. There are six reinforcing pins 404 symmetrically distributed on the left and right, with four distributed at the top and two distributed at the bottom. The sealing ring 501, cylindrical cup 502, threaded ring 503 and conical cup 504 are integrated into one structure. The interior of the integrated structure is hollow. The nozzle insertion cavity 505 is conical, with a thicker front end and a narrower rear end. The inner wall of the nozzle insertion cavity 505 is made of rubber material. The front cover plate 401 and docking shell 402 can be sealed and spliced ​​with the front end of the cabin 301, so that the cavity inside the front cover plate 401 and docking shell 402 is connected to the cavity inside the cabin 301. Then, through the nozzle insertion cavity 505 opened on the inner side of the front end of the sealing cup 5, it can fit with the structure at the rear end of the paint nozzle of the spray gun type paint dispensing device. Together with the clamping module 2, it plays a role in limiting and fixing the spray gun type paint dispensing device. At the same time, the contact end between the spray gun type paint dispensing device and the sealing cup 5 is sealed by blocking.

[0034] like Figures 10 to 15 As shown, in this embodiment, the sealing circular plate 14 includes a positioning plate 141, a sealing gasket 142, a central hole 143, and a positioning hole 144. The upper end of the positioning plate 141 is provided with a sealing gasket 142, and the middle part of the upper end of the sealing gasket 142 is provided with a central hole 143. The outer side of the central hole 143 is provided with a positioning hole 144. The cleaning brush 15 includes a rotating shaft 151, a brush sleeve 152, and a limiting block 153. The middle part of the outer end of the rotating shaft 151 is provided with a brush sleeve 152, and the upper and lower sides of the brush sleeve 152 are provided with limiting blocks 153.

[0035] The positioning plate 141 and the sealing gasket 142 are integrated. The sealing gasket 142 is made of rubber material. The central hole 143 and the positioning hole 144 both penetrate the interior of the sealing gasket 142 and the positioning plate 141 from top to bottom. The inner diameter of the central hole 143 is compatible with the outer diameter of the middle shaft of the driving wheel in the gear set 13. There are eight positioning holes 144 arranged in a ring. The upper and lower ends of the rotating shaft 151 penetrate the middle of the brush sleeve 152 and continue to extend to the outer side of the upper and lower ends. There are two limit blocks 153 symmetrically distributed in the upper and lower parts. The two limit blocks 153 and the rotating shaft 151 are threaded together. The lower end of the rotating shaft 151 extends to the inner side of the middle shaft of the driven wheel in the gear set 13. The splicing end is reinforced with a screw pin.

[0036] The positioning plate 141, along with the center hole 143 and the positioning hole 144, can be used to position the gear set 13 and the cleaning brush 15, ensuring that the vertical angles of the two are matched. At the same time, the sealing gasket 142, along with the sealing adhesive, seals the contact ends of the gear set 13, the cleaning brush 15, and the positioning plate 141. Subsequently, the gear set 13 drives the cleaning brush 15 to rotate, and the wiping head on the upper end of the drive wheel in the gear set 13 cleans the outer end and front end of the paint nozzle of the spray gun-type paint dispensing device.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0038] The cleaning structure for the paint nozzle of the eggshell art paint dispensing equipment includes the following steps when in use; Step 1: First, before starting work, the device is fixedly installed on the upper end of the operating table by bolts through the screw holes opened on the front and rear sides of the upper end of the support module 1. Then, the clamping module 2 and the cleaning chamber 3 are assembled and reinforced with bolts. Step 2: When it is necessary to clean the residue on the outer end of the paint nozzle, the paint dispensing device can be placed on the clamping module 2. The handle and the material storage connection end of the paint dispensing device are limited and fixed by the lower groove 202 and the upper groove 203 set on the upper and lower sides of the front end of the frame 201. At the same time as the limit is fixed, the paint nozzle of the paint dispensing device will penetrate the interior of the sealing cup 5 and enter the cleaning chamber 3, and continue to extend to the middle area of ​​the sealing bottom cylinder 8. Step 3: Then turn on the servo motor 11 installed in the middle of the lower end of the sealed bottom cylinder 8, so that it drives the driving wheel in the middle of the gear set 13 to rotate. The driving wheel in the middle of the gear set 13 and the driven wheels distributed in an outer ring are meshed together, which can drive the cleaning brush 15 installed on the upper end of the driven wheel to start rotating synchronously. Together with the wiping head installed on the upper end of the driving wheel, the residual substances on the paint nozzle are cleaned from the front and the side. Step 4: When the painting work is completed and the inside of the paint nozzle needs to be cleaned, insert the paint dispensing device directly into the placement cup 6 from the top, so that the paint dispensing head of the paint dispensing device extends into the inside of the filter cartridge 9. Then, connect it to the external ultrasonic generator through the electrical connector 304 set at the outer end of the chamber 301, so as to convert the mains power into a high frequency electrical signal, drive the ultrasonic transducer 10 installed inside the lower end of the filter cartridge 9 to start working. Through the ultrasonic transducer 10, the ultrasonic cavitation effect is used inside the filter cartridge 9 to generate countless tiny vacuum bubbles in the cleaning fluid. When these bubbles burst, they generate strong shock waves that act on the inner and outer surfaces of the paint nozzle and the vortex cavity of the spray cap, breaking and peeling off stubborn cement, cured paint, etc. Step 5: When it is necessary to clean the inside of the cleaning chamber 3, first open the valve connected to the lower end of the cleaning chamber 3 to remove the cleaning fluid and impurities inside the cleaning chamber 3. If you want to clean it thoroughly, you only need to separate the placement cup 6 and the sealing bottom cylinder 8 from the cleaning chamber 3 to complete the internal cleaning work. At the same time, since the entire mechanical structure is relatively simple, after cleaning, you only need to assemble and reinforce it to complete the reset. The overall disassembly and assembly work is relatively convenient and quick.

[0039] The working principle of the technical solution provided by this invention is as follows: The clamping module 2 limits and clamps the handle and storage connection end of the spray gun-type paint dispenser. Simultaneously, the paint nozzle of the spray gun-type paint dispenser tilts and penetrates the interior of the sealed cup 5 into the cleaning chamber 3, extending further to the middle area inside the sealed bottom cylinder 8. Then, the servo motor 11 is turned on, driving the drive wheel in the middle of the gear set 13 to rotate. The drive wheel in the middle of the gear set 13 is meshed with the driven wheels distributed in a ring on the outer side, thus driving the cleaning brush 15 mounted on the upper end of the driven wheel to rotate synchronously. Together with the wiping head mounted on the upper end of the drive wheel, it wipes away the residue on the paint nozzle from both the front and side. Wipe and clean; through the set placement cup 6, an operator holds a spray gun-type paint dispensing device, with its paint nozzle directly penetrating the inner side of the placement cup 6 and continuing to extend downward into the interior of the filter cartridge 9. Then, through the electrical connector 304 set at the outer end of the chamber 301, it is connected to an external ultrasonic generator, thereby converting the mains power into a high-frequency electrical signal, driving the ultrasonic transducer 10 installed inside the lower end of the filter cartridge 9 to start working. Through the ultrasonic transducer 10, the ultrasonic cavitation effect is used inside the filter cartridge 9 to generate countless tiny vacuum bubbles in the cleaning fluid. When these bubbles burst, they generate strong shock waves that act on the inner and outer surfaces of the paint nozzle and the vortex cavity of the spray cap, breaking and peeling off stubborn cement, cured paint, etc.
