[0032] Please see Figures 1-3 The waterproof structure 100 for the motor according to the present application includes a motor 10 and a connecting sleeve 20. The motor 10 includes a main body 11 and a drive shaft 12. The drive shaft 12 extends out of the main body 11 and passes through the end face of the main body 11. The bottom surface of the connecting sleeve 20 is mounted on the end face. The connecting sleeve 20 has a through hole 23 and a drain hole 24. The drive shaft 12 passes through the through hole 23. The drain hole 24 communicates with the through hole 23 and passes through the outer peripheral surface and the bottom surface of the connecting sleeve 20.
[0033] The waterproof structure 100 of the motor in this embodiment installs the connecting sleeve 20 on the end face of the motor body 11 and drains the liquid in the through hole 23 from the drain hole 24 in a timely manner through the through hole 23, thereby preventing the liquid from seeping into the motor body 11 along the drive shaft 12, thus preventing the motor 10 from short-circuiting due to water ingress and protecting the motor 10 to work normally.
[0034] Specifically, the main body 11 of the motor 10 can be a cuboid structure, and a drive shaft 12 can extend from one end face along the length direction of the main body 11. The drive shaft 12 can pass through one end face along the length direction of the main body 11 and rotate when the motor 10 is working. The bottom surface of the connecting sleeve 20 can face the main body 11 and be fitted to the end face of the main body 11. The through hole 23 can pass through the central shaft of the connecting sleeve 20, and the drive shaft 12 can pass through the through hole 23 and extend part of its end face. The drain hole 24 can connect the outside of the connecting sleeve 20 to the through hole 23. The outer peripheral surface of the connecting sleeve 20 through which the drain hole 24 passes can be the outer surface of the connecting sleeve 20 that contacts the outside, and the bottom surface can be the side that fits against the main body 11. When there is water or liquid inside the rotating shaft of the motor 10, the drain hole 24 can drain the water or liquid in the through hole 23, preventing water or other liquids from entering the motor 10 along the drive shaft 12.
[0035] Please see Figures 1-3 In some embodiments, a water-spraying component 40 is fixed on the drive shaft 12, and the water-spraying component 40 is exposed through the drain hole 24.
[0036] In this way, the drive shaft 12 drives the water-throwing component 40 to throw the water on the drive shaft 12 out through the drain hole 24 during the operation of the motor 10, thereby improving the drainage efficiency.
[0037] Specifically, a water-spraying component 40 can be fixed on the end face of the drive shaft 12 near the main body 11 of the motor 10. The water-spraying component 40 can be accommodated in the through hole 23 and can be partially exposed through the drain hole 24.
[0038] Please see Figures 1-4 In some embodiments, the water-spraying component 40 is annular and sleeved on the drive shaft 12, and the water-spraying component 40 is sealed to the drive shaft 12.
[0039] Thus, the ring-shaped water-throwing component 40 is conducive to throwing water along the drain hole 24 under the drive shaft 12. The water-throwing component 40, which is sealed to the drive shaft 12, can prevent water from entering the motor 10 through the gap between the water-throwing component 40 and the drive shaft 12 during the water-throwing process.
[0040] Specifically, the structure of the water-spraying component 40 can be a circular cylindrical structure surrounding the drive shaft 12, and the water-spraying component 40 and the drive shaft 12 can be sealed together by a sealing structure such as waterproof rubber. One end of the water-spraying component 40 can be close to the main body 11, and the other end can extend along the length direction of the drive shaft 12.
[0041] Please see Figures 1-3 In some embodiments, the high point of the drain hole 24 is higher than the high point of the water-spinning component 40.
[0042] Thus, the high point of the drain hole 24 is higher than the high point of the water-throwing component 40, which ensures that the water thrown out by the water-throwing component 40 under the drive of the drive shaft 12 can be discharged through the drain hole 24.
[0043] Specifically, the highest point of the drain hole 24 can be the height of the end face of the drain hole 24 furthest from the bottom surface, and the highest point of the water-slinging component 40 can be the height of the water-slinging component 40 furthest from the end face of the main body 11 along its own thickness direction. The highest point of the drain hole 24 is higher than the highest point of the water-slinging component 40, or the diameter height of the drain hole 24 along the length of the drive shaft 12 can be greater than the height of the water-slinging component 40 along the length of the drive shaft 12.
[0044] Please see Figures 1-3 In some embodiments, there are multiple drainage holes 24, which are arranged at intervals along the circumference of the connecting sleeve 20.
[0045] Thus, the arrangement of multiple drainage holes 24 can improve drainage efficiency. The drainage holes 24 arranged at intervals along the circumference of the connecting sleeve 20 make drainage more uniform and further improve drainage efficiency.
[0046] Specifically, multiple drainage holes 24 can be arranged around the circumference of the connecting sleeve 20. When there are two drainage holes 24, the two drainage holes 24 can be symmetrically arranged on the circumference of the connecting sleeve 20. When there are more than two drainage holes 24, the multiple drainage holes 24 can be arranged at equal intervals along the circumference of the connecting sleeve 20.
[0047] Please see Figures 1-3 In some embodiments, the main body 11 includes a body 111 and a flange 112 connected to the body 111. The flange 112 protrudes from the side of the main body 11 and includes an end face. The connecting sleeve 20 is fixedly connected to the flange 112.
[0048] Thus, the flange 112 being mounted on the body 111 and fixedly connected to the body 111 facilitates the connection and fixation of the motor 10 and the connecting sleeve 20.
[0049] Specifically, the flange 112 can be provided at one end of the body 111 extending from the drive shaft 12. The flange 112 can be in the form of a ring structure, and the annular circumferential surface of the outer edge of the flange 112 can protrude from each side of the body 11 of the motor 10. The end face of the flange 112 can be the surface of the flange 112 that is away from the side that contacts the body 111.
[0050] Please see Figures 1-3 In some embodiments, the flange 112 includes a first circumferential surface 1122, and the outer circumferential surface of the connecting sleeve 20 includes a second circumferential surface 211. Both the first circumferential surface 1122 and the second circumferential surface 211 surround the drive shaft 12. The first circumferential surface 1122 and the second circumferential surface 211 are aligned, and the drain hole 24 penetrates the second circumferential surface 211.
[0051] Thus, aligning the first circumferential surface 1122 with the second circumferential surface 211 and surrounding the drive shaft 12 can protect the drive shaft 12 and prevent water or other liquids from flowing into the drive shaft 12 from the gap between the first circumferential surface 1122 and the second circumferential surface 211 along the connecting sleeve 20.
[0052] Specifically, the first circumferential surface 1122 can be an annular circumferential surface of the side of the flange 112. The first circumferential surface 1122 can axially surround the drive shaft 12. The second circumferential surface 211 can be an annular circumferential surface located on the connecting sleeve 20, close to and aligned with the side of the first circumferential surface 1122. The second circumferential surface 211 can axially surround the drive shaft 12, and the drain hole 24 can penetrate the second circumferential surface 211 along its surface toward the drive shaft 12.
[0053] Please see Figures 1-3 In some embodiments, the connecting sleeve 20 includes a first portion 21 and a second portion 22 connected to the first portion 21. The first portion 21 has a second circumferential surface 211, which is annular. The cross-sectional area of the second portion 22 is smaller than that of the first portion 21. A drain hole 24 is formed in the first portion 21.
[0054] Thus, the connecting sleeve 20 can connect to and protect the drive shaft 12 of the motor 10 by setting the first part 21, while the second part 22 can further prevent the liquid flowing down the protective wall 33 in the atomizing disc 30 from entering the drive shaft 12 along the connecting sleeve 20.
[0055] Specifically, the first part 21 can be the portion of the connecting sleeve 20 near the flange 112. The second circumferential surface 211 of the first part 21 can be annular, and can be composed of multiple stepped annular structures. The drain hole 24 can be located on the first part 21 and penetrate through the second circumferential surface 211. The second part 22 can be an annular columnar structure close to the first part 21. The diameter of the outer circumferential surface of the second part 22 can be smaller than the diameter of the outer circumferential surface of the first part 21, so that the cross-sectional area of the second part 22 perpendicular to the drive shaft 12 can be smaller than the cross-sectional area of the first part 21 perpendicular to the drive shaft 12.
[0056] Please see Figures 2-4 In some embodiments, the drive shaft 12 includes a mounting end 121 located away from the main body 11, which extends out of the connecting sleeve 20. The motor waterproof structure 100 of the battery thin film spraying device 1000 also includes an atomizing disc 30, which includes a disc body 31, a rotating shaft 32, and a protective wall 33. The rotating shaft 32 is connected to the center of the disc body 31, the mounting end 121 is inserted into the rotating shaft 32, and the protective wall 33 is connected to the disc body 31 and surrounds the mounting end 121. The protective wall 33 surrounds the outside of the connecting sleeve 20.
[0057] Thus, the motor waterproofing device of the battery thin film spraying device 1000 is connected to the connecting sleeve 20 by setting a protective wall 33 on the rotating shaft 32 on the atomizing disk 30. This allows water or spraying agent flowing out of the atomizing disk 30 during the spraying process to flow along the protective wall 33 to the connecting sleeve 20, and then be guided along the connecting sleeve 20 to the outside of the motor 10, preventing the spraying agent from flowing into the motor 10 along the drive shaft 12, thereby preventing the motor 10 from short-circuiting or being damaged.
[0058] Specifically, the mounting end 121 of the drive shaft 12 extends out of the upper end face of the connecting sleeve 20. The mounting end 121 may have a threaded structure, which allows the mounting end 121 to be inserted into the rotating shaft 32 of the atomizing disc 30 for stable connection.
[0059] The atomizing disc 30 can be used to hold the reagents used for spraying in the battery thin film spraying device 1000. The disc body 31 can be the main body 11 of the atomizing disc 30, and the disc body 31 can be disc-shaped and have an inclined outer peripheral surface. A rotating shaft 32 can be connected to the center of the disc body 31 of the atomizing disc 30, and the rotation of the rotating shaft 32 can drive the disc body 31 to rotate. The part of the mounting end 121 that protrudes from the connecting sleeve 20 can be inserted into the rotating shaft 32 and fixedly connected to the rotating shaft 32. The protective wall 33 can be connected to the disc body 31 on one side connected to the rotating shaft 32, and can surround and encircle the rotating shaft 32 around the mounting end 121. The end of the protective wall 33 away from the connecting disc body 31 can be close to the outer end face of the connecting sleeve 20.
[0060] Please see Figure 5The battery thin film spraying apparatus 1000 of the present application embodiment includes the motor waterproof structure 100 of the battery thin film spraying apparatus 1000 of any of the above embodiments.
[0061] The battery thin film spraying apparatus 1000 of this application improves the waterproofness of the motor 10 during the battery thin film spraying process by providing a motor waterproof structure 100, thereby improving the reliability of the battery spraying apparatus and reducing malfunctions.
[0062] Specifically, the motor waterproof structure 100 can be installed inside the battery thin film spraying device 1000. When the motor waterproof structure 100 is working, the reagent used for spraying can be sprayed out from the spraying port of the battery thin film spraying device 1000.
