[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1 and Figure 2 A vacuum recyclable motor paint impregnation device includes a base 3, a housing 1, and a support plate 5. The housing 1 and support plate 5 are fixedly connected to the base 3. The housing 1 has an opening at the top. A lid 2 is provided on the top of the housing 1 to match the opening of the housing 1. The lid 2 is used to seal the top opening of the housing 1. In this embodiment, the housing 1 is rotatably connected to one side of the lid 2, and the lid 2 can be flipped to open or close the housing.

[0022] The box cover 2 is provided with a connecting pipe 21, which is connected to a first pipe 8 and a second pipe 9 via a Y-shaped pipe. The first pipe 8 is used to connect to a vacuum air pump to adjust the air pressure inside the box body 1, and the second pipe 9 is used to connect the paint liquid to the box body 1. In this embodiment, a second valve 81 is provided on the first pipe 8, and a third valve 91 is provided on the second pipe 9 to enable the first pipe 8 and the second pipe 9 to operate independently.

[0023] The above-mentioned first pipe 8 can be connected to the air inlet or outlet of the vacuum air pump. When the interior of the box body 1 requires a negative pressure or vacuum state, the first pipe 8 can be connected to the air inlet of the vacuum air pump, and the vacuum air pump extracts air from the interior of the box body 1; when the interior of the box body 1 requires a high pressure state, the first pipe 8 can be connected to the air outlet of the vacuum air pump, and the vacuum air pump exhausts the interior of the box body 1.

[0024] Furthermore, a support plate 5 is located on one side of the housing 1 and is used to house the motor. In this embodiment, the support plate 5 is disc-shaped. A liquid outlet pipe 51 is provided on the support plate 5. The liquid outlet pipe 51 is connected to the housing 1 via a liquid conduit 6. One end of the liquid conduit 6 is connected to the bottom of the housing 1, and the other end of the liquid conduit 6 passes through the support plate 5 and is connected to the bottom of the liquid outlet pipe 51.

[0025] In this embodiment, when a small-volume motor is dipped in paint, the small-volume motor is placed inside the box 1 filled with paint liquid, and the motor dipped in paint can be completed inside the box 1.

[0026] When dipping large motors, refer to Figure 3 , place the large-volume motor 10 on the upper surface of the support plate 5, and keep the liquid outlet pipe 51 inside the large-volume motor 10. The large-volume motor 10 and the upper surface of the support plate 5 are sealed by glue, so that the large-volume motor 10 and the upper surface of the support plate 5 form a container with an open top. The liquid outlet pipe 51 is used to supply or discharge paint liquid into the large-volume motor 10.

[0027] When the large-volume motor 10 is being dipped in paint, the first pipe 8 is connected to the air outlet of the vacuum air pump, and the vacuum air pump exhausts the interior of the housing 1, generating high-pressure gas inside the housing 1. The high-pressure gas pressurizes the paint liquid inside the housing 1, and the paint liquid inside the housing 1 can enter the interior of the large-volume motor 10 through the liquid guide tube 6 and the liquid outlet tube 51, and the winding inside the large-volume motor 10 is dipped in paint. When the paint dipping is completed, the first pipe 8 is connected to the air inlet of the vacuum air pump, and the vacuum air pump evacuates the interior of the housing 1, so that a negative pressure or vacuum state is formed inside the housing 1. The paint liquid inside the large-volume motor 10 can enter the housing 1 again through the liquid outlet tube 51 and the liquid guide tube 6, realizing paint liquid recovery.

[0028] It is worth noting that the large-volume motor 10 in this embodiment is a motor that cannot be placed inside the box 1 , and the small-volume motor is a motor that can be placed inside the box 1 .

[0029] In this embodiment, a drain pipe 11 is further provided at the bottom of the housing 1 for discharging the paint liquid from the housing 1. The aforementioned liquid guide pipe 6 is connected to the drain pipe 11. A first valve 61 is provided on the liquid guide pipe 6, and a fourth valve is provided on the drain pipe 11 to enable the liquid guide pipe 6 and the drain pipe 11 to operate independently.

[0030] In this embodiment, a barometer 7 is provided on the box cover 2 , and the barometer 7 is used to detect the air pressure inside the box body 1 .

[0031] In this embodiment, an observation window 22 is further provided on the box cover 2 . The observation window 22 is provided with a transparent lens to facilitate staff to observe the situation inside the box body 1 .

[0032] In this embodiment, a universal wheel 4 with a brake is provided at the bottom of the base 3 to facilitate the movement of the vacuum recyclable motor paint dipping device.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
