[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a surface coating device for automotive interior processing provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure. Figure 3 for Figure 1 The diagram shows a cross-sectional structure. Figure 4 for Figure 3 The enlarged schematic diagram of part A is shown. A surface coating apparatus for automotive interior processing includes: a spray bottle 1;

[0028] A fixing frame 3 is fixedly installed on the bottom of the spray bottle 1;

[0029] A support plate 4 is fixedly installed on the inner side of the fixed frame 3. A dual-head motor 41 is fixedly installed inside the support plate 4. A scraper 42 is fixedly installed on one output end of the dual-head motor 41, and a disc 43 is fixedly installed on the other output end of the dual-head motor 41. A connecting rod 47 is rotatably connected to one end of the bottom of the disc 43, and a rotating seat 46 is rotatably connected to one end of the connecting rod 47. A piston plate 45 is fixedly installed on one side of the rotating seat 46. An inflation pipe 44 is fixedly installed at the bottom of the inner side of the fixed frame 3. The piston plate 45 is slidably connected to the inner side of the inflation pipe 44. An air inlet one-way valve 49 is fixedly installed at one end of the inflation pipe 44, and an air outlet one-way valve 48 is fixedly installed at the top end of the inflation pipe 44. A pipe 40 is fixedly installed at the output end of the air outlet one-way valve 48, and an air outlet nozzle 411 is fixedly installed at the output end of the pipe 40.

[0030] A support ring 2 is fixedly installed at the bottom of the spray bottle 1, and the support ring 2 is disposed on the outer side of the fixed frame 3.

[0031] Ventilation openings 31 are provided at both ends of the bottom of the fixed frame 3, and ventilation windows 32 are fixedly installed at both ends of the bottom of the fixed frame 3, with the ventilation windows 32 located at the bottom of the ventilation openings 31.

[0032] The side of the scraper 42 is attached to the side of the spray bottle 1.

[0033] The pipe 40 is disposed inside the spray bottle 1, and the air nozzle 411 is disposed on the top of the inner side of the spray bottle 1.

[0034] When the disc 43 rotates, it can drive the connecting rod 47 to move, thereby causing the connecting rod 47 to drive the piston plate 45 to reciprocate inside the air tube 44, thereby increasing the pressure inside the spray bottle 1.

[0035] When in use, a pressure relief valve can be installed on the air tube 44. When the pressure inside the spray bottle 1 is too high, the pressure relief valve can automatically relieve the pressure inside the air tube 44.

[0036] The heat generated by the dual-head motor 41 can be discharged through the ventilation window 32 and the ventilation opening 31;

[0037] The support plate 41 increases the stability of the dual-head motor 41 during rotation.

[0038] The working principle of the surface coating device for automotive interior processing provided by this utility model is as follows:

[0039] When in use, the user starts the dual-head motor 41, which drives the scraper 42 to rotate, thereby making the scraper 42 stir and mix the material inside the spray bottle 1, and also scrape off the material adhering to the inner wall of the spray bottle 1.

[0040] At the same time, the other end of the dual-head motor 41 drives the disc 43 to rotate, which in turn drives the connecting rod 47 to rotate. This causes one end of the connecting rod 47 to pull the rotating seat 46 and the piston plate 45, allowing external gas to enter the inflation pipe 44 through the inlet one-way valve 49, then through the outlet one-way valve 48 into the pipe 40, and finally through the outlet nozzle 411 into the spray bottle 1, pressurizing the inside of the spray bottle 1.

[0041] Compared with related technologies, the surface coating device for automotive interior processing provided by this utility model has the following advantages:

[0042] The dual-head motor 41, scraper 42, disc 43, air inlet pipe 44, piston plate 45, rotating seat 46, connecting rod 47, exhaust check valve 48, intake check valve 49, pipe 40, and exhaust nozzle 411 work together to scrape and stir the paint for automotive interior processing adhering to the inner wall of the spray bottle 1 while the dual-head motor 41 drives the scraper 42 to do so. At the same time, it can also pressurize the inside of the spray bottle 1. This eliminates the need for manual operation by the staff, reducing the number of operation steps and increasing work efficiency.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 5 Based on the first embodiment of this application, which provides a surface coating apparatus for automotive interior processing, the second embodiment of this application proposes another surface coating apparatus for automotive interior processing. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the difference in the second embodiment of this application regarding the surface coating device for automotive interior processing is that the inner side of the spray bottle 1 is provided with a limiting ring 51, and both ends of the limiting ring 51 are fixedly installed with support rods 51.

[0046] One end of the support rod 51 is fixedly installed on the other side of the scraper 42.

[0047] The working principle of the surface coating device for automotive interior processing provided by this utility model is as follows:

[0048] When in use, two support rods 5 are installed between the two scrapers 42, and then a limiting ring 51 is installed between the two support rods 5. In this way, the top of the two scrapers 42 can be limited when in use.

[0049] Compared with related technologies, the surface coating device for automotive interior processing provided by this utility model has the following advantages:

[0050] By using the support rod 5 and the limiting ring 51 in conjunction with each other, the tops of the two scrapers 42 can be limited during use, increasing the stability of the two scrapers 42 when they rotate.
