[0004] The technical solution in the prior art document has the effect of rapid cleaning using cleaning agents, but the defects are also more obvious. For example, the cleaning effect of the cleaning agent is limited, and it lacks a structure to effectively clean the internal pipes of the paint spray gun. Especially for stubborn paint, this solution has a poor cleaning effect on the internal pipes of the paint spray gun. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rapid cleaning device for paint spray gun pipes, which solves the problem that cleaning agents have limited cleaning effects and lack a structure for effectively cleaning the internal pipes of paint spray guns, especially for stubborn paint residues, where this solution has poor cleaning effects on the internal pipes of paint spray guns.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid cleaning device for paint spray gun pipes, comprising a cleaning basin, a brush assembly provided on the surface of the cleaning basin, a plurality of spring structures distributed equidistantly from left to right on the side wall of the cleaning basin, a pressing plate fixedly connected to one end of each spring structure, and an ultrasonic cleaning assembly provided inside the bottom of the cleaning basin.

[0007] The brush assembly includes a drive motor fixedly connected to the outer wall of the washing basin. The output end of the drive motor passes through the washing basin into its interior and is fixedly connected to a connecting rod. A brushing layer is fixedly connected to the surface of the connecting rod.

[0008] The spring structure includes a fixed rod fixedly connected to the side wall of the washing basin, a sliding tube slidably connected to the surface of the fixed rod, a spring fixedly connected to the side of the sliding tube, and a fixed rod fixedly connected to the side of the spring.

[0009] The ultrasonic cleaning assembly includes an ultrasonic transducer group fixedly connected inside the cavity. An ultrasonic generator is electrically connected to the surface of the ultrasonic transducer group, and the ultrasonic generator is fixedly connected to the bottom surface of the cleaning basin.

[0010] In one specific embodiment, the output end of the drive motor is coaxially and fixedly connected to the connecting rod, and the brushing layer is distributed along the axial and circumferential directions of the connecting rod.

[0011] In one specific embodiment, the slide tube is fixedly connected to the extrusion plate, and the slide tube slides along the axial direction of the fixed rod.

[0012] In one specific embodiment, the two ends of the spring are fixedly connected to the side of the slide tube and the side of the fixed rod, respectively, and the axial direction of the spring is the same as the axial direction of the fixed rod.

[0013] In one specific embodiment, the extrusion plate clamps the spray gun pipe between the extrusion plate and the scrubbing layer by the elastic rebound force of the spring structure.

[0014] In one specific embodiment, the ultrasonic transducer group is started synchronously with the ultrasonic generator, and the vibration generated by the ultrasonic transducer group is transmitted to its interior through the bottom of the cleaning basin.

[0015] Compared with the prior art, this utility model provides a rapid cleaning device for paint spray gun pipes, which has the following beneficial effects:

[0016] In the technical solution disclosed in this utility model, the brush assembly drives the brushing layer to rotate via a drive motor, mechanically brushing the surface of the pipe; the spring structure uses the sliding tube and spring rebound to drive the extrusion plate to clamp the pipe onto the brushing layer, ensuring brushing stability; the ultrasonic cleaning assembly generates high-frequency vibrations through the coordinated action of the ultrasonic transducer group and the ultrasonic generator, which, combined with the mechanical action of the brushing layer, achieves dual cleaning of stubborn coatings inside and outside the pipe through mechanical and cavitation effects, significantly improving cleaning efficiency.

[0017] The brush assembly and ultrasonic cleaning assembly of this invention allow for efficient operation. During operation, the paint spray gun pipe is inserted between the brush assembly and the spring structure within the cleaning basin. Pressing the extrusion plate causes it to slide along the fixed rod, compressing the spring and placing the pipe on the surface of the cleaning layer. Releasing the extrusion plate causes the spring to return the sliding pipe to its original position, clamping the pipe between the extrusion plate and the cleaning layer. Starting the drive motor drives the connecting rod to rotate the circumferentially distributed cleaning layer at high speed, removing surface paint through friction between the brush bristles and the pipe surface. Simultaneously, the ultrasonic generator is activated, driving the ultrasonic transducer assembly to generate high-frequency vibrations. These vibrations are transmitted through the bottom of the cleaning basin to the internal cleaning fluid, triggering cavitation. The resulting micro-jet streams impact the inner and outer walls of the pipe, working in conjunction with the mechanical action of the cleaning layer to decompose stubborn paint residue. The elastic clamping of the spring structure ensures stable contact of the pipe during vibration and rotation, preventing cleaning blind spots caused by displacement and ultimately achieving efficient and thorough cleaning.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Figures 1-4In one embodiment of this utility model, a rapid cleaning device for paint spray gun pipes includes a cleaning basin 1, a brush assembly 2 is provided on the surface of the cleaning basin 1, and a plurality of spring structures 3 are distributed equidistantly from left to right on the side wall of the cleaning basin 1. One end of the spring structure 3 is fixedly connected to a pressing plate 4, and a cavity is opened at the bottom of the cleaning basin 1. An ultrasonic cleaning assembly 5 is provided inside the cavity.

[0026] The specific problem addressed in this embodiment is the limitation of cleaning agents in terms of cleaning effect, and the lack of a structure for effectively cleaning the internal pipes of paint spray guns, especially for stubborn paint residue. This invention solves the problem of poor cleaning effect on the internal pipes of paint spray guns by using a brush assembly 2 to drive the brush layer 23 to rotate via a drive motor 21, mechanically brushing the pipe surface; a spring structure 3 uses a sliding tube 32 and a spring 33 to drive a pressing plate 4 to clamp the pipe onto the brush layer 23, ensuring brushing stability; an ultrasonic cleaning assembly 5 uses an ultrasonic transducer group 51 and an ultrasonic generator 52 to generate high-frequency vibrations, which, combined with the mechanical action of the brush layer 23, achieves dual cleaning of stubborn paint inside and outside the pipes through mechanical and cavitation effects, significantly improving cleaning efficiency.

[0027] The brush assembly 2 includes a drive motor 21 fixedly connected to the outer wall of the cleaning basin 1. The output end of the drive motor 21 passes through the cleaning basin 1 into its interior and is fixedly connected to a connecting rod 22. A brushing layer 23 is fixedly connected to the surface of the connecting rod 22. The ultrasonic cleaning assembly 5 includes an ultrasonic transducer group 51 fixedly connected to the cavity. An ultrasonic generator 52 is electrically connected to the surface of the ultrasonic transducer group 51, and the ultrasonic generator 52 is fixedly connected to the bottom surface of the cleaning basin 1. In this specific embodiment, the output end of the drive motor 21 is coaxially fixedly connected to the connecting rod 22, and the brushing layer 23 is distributed along the axial and circumferential directions of the connecting rod 22. During operation, the paint spray gun pipe is inserted between the brush assembly 2 and the spring structure 3 inside the cleaning basin 1. The pressing plate 4 is pressed to make it slide along the fixed rod 31, driving the slide tube 32 to slide and compress the spring 33. At this time, the pipe is placed on the surface of the brushing layer 23. After releasing the pressing plate 4, the spring 33 rebounds and pushes the slide tube 32 back to its original position, so that the pressing plate 4 and the brushing layer 23 clamp the pipe together. The drive motor 21 is activated, driving the connecting rod 22 to rotate the circumferentially distributed brush layer 23 at high speed. The friction between the brush bristles and the pipe surface removes the surface coating. Simultaneously, the ultrasonic generator 52 is activated, driving the ultrasonic transducer assembly 51 to generate high-frequency vibrations. These vibrations are transmitted through the bottom of the cleaning basin 1 to the internal cleaning fluid, triggering a cavitation effect. The resulting micro-jet streams impact the inner and outer walls of the pipe, working in conjunction with the mechanical action of the brush layer 23 to decompose stubborn coating residues. The elastic clamping of the spring structure 3 ensures stable contact of the pipe during vibration and rotation, avoiding cleaning blind spots caused by displacement, ultimately achieving efficient and thorough cleaning.

[0028] In this specific embodiment, the two ends of the spring 33 are fixedly connected to the side of the slide tube 32 and the side of the fixing rod 31, respectively, and the axial direction of the spring 33 is the same as the axial direction of the fixing rod 31; the extrusion plate 4 clamps the spray gun pipe between the extrusion plate 4 and the brushing layer 23 through the elastic rebound force of the spring structure 3; the linear compression / rebound of the spring 33 provides the clamping force of the pipe to avoid lateral displacement, and the direct force of the spring ensures the stability of the clamping.

[0029] In this specific embodiment, the ultrasonic transducer group 51 and the ultrasonic generator 52 are started synchronously, and the vibration generated by the ultrasonic transducer group 51 is transmitted to its interior through the bottom of the cleaning basin 1; the ultrasonic cavitation effect penetrates the inner and outer walls of the pipe, and works with brushing to break down stubborn coatings. The high-frequency vibration forms micro-jet impacts in the liquid, which, combined with mechanical brushing, thoroughly cleans the surface.

[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
