[0040] Referring to Figures 2 to 4 , the first embodiment of the embedded imaging device capable of automatic drainage according to the present invention is suitable for being embedded in a ground 9 (see Figure 6 ) and is used to photograph vehicle license plates. The embedded imaging device capable of automatic drainage is suitable for being installed by a power unit 91 (see Figure 6 ) and electrically connected to the power unit 91. In this embodiment, the power unit 91 is exemplified by a battery, but in some embodiments, the present invention can also be electrically connected to an external power source, and the power unit 91 can be omitted. This embodiment includes a cylinder base unit 200, an electronic component unit 6, and an automatic drainage unit 7.

[0041] Referring to Figure 2 , Figure 3 andFigure 5 The barrel base unit 200 includes a barrel body 23, a water collecting box 24, an upper cover group 400, and a nozzle group 25. The barrel body 23 has an open end 231 and a closed end 232 which are oppositely arranged in a top-bottom direction Z. In this embodiment, the barrel body 23 has an annular ring portion 233, a first barrel portion 234 extending downward from the ring portion 233, and a second barrel portion 235 adjacent to the first barrel portion 234 and extending downward from the ring portion 233. The length of the first barrel portion 234 in the top-bottom direction Z is greater than the length of the second barrel portion 235 in the top-bottom direction Z. The open end 231 is formed on the ring portion 233. The first barrel portion 234 forms a first chamber 236 with an open top end. The second barrel portion 235 forms a second chamber 237 with an open top end. The closed end 232 is defined jointly by the bottoms of the first barrel portion 234 and the second barrel portion 235. The first chamber 236 is adapted to accommodate the power unit 91.

[0042] Refer to Figures 3 to 5 The water collecting box 24 is installed in the second chamber 237 of the barrel body 23 and its top extends into the ring portion 233. In this embodiment, the water collecting box 24 is detachably installed on the barrel body 23, so the water collecting box 24 can be taken out from the second chamber 237, which is convenient for cleaning the water collecting box 24.

[0043] The water collecting box 24 is formed with a water collecting chamber 241, an opening 242, a positioning block 243, a water guiding inclined surface 244, and a window portion 245. The water collecting chamber 241 is located between the open end 231 and the closed end 232 of the barrel body 23 and is independent of the first chamber 236 in space, so that the first chamber 236 can be kept dry and the power unit 91 can be prevented from being affected by moisture.

[0044] Refer to Figure 3 , Figure 4 and Figure 6, in this embodiment, the water collecting chamber 241 is divided into a left half space 246 and a right half space 247 that are connected and communicate with each other. The left half space 246 is located in the annular part 233 of the cylinder body 23, and the right half space 247 is located between the annular part 233 and the second chamber 237. The opening 242 is located on the top side of the right half space 247 and is spatially connected to the water collecting chamber 241. The positioning block 243 is adjacent to the opening 242, and its top side has an inclined surface. The water guiding inclined surface 244 is adjacent to the side of the positioning block 243 opposite to the opening 242 and slopes downward toward the water collecting chamber 241. The window part 245 is located on the top side of the water collecting box and can transmit light. In this embodiment, the window part 245 is composed of a U-shaped block located beside the opening 242 opposite to the positioning block 243 and a transparent thin sheet installed between the U-shaped block and the electronic component unit 6, but is not limited thereto.

[0045] Refer to Figure 2 , Figure 3 and Figure 5 , the upper cover group 400 is used to cover the open end 231 of the cylinder body 23 to close the water collecting chamber 241. In some embodiments, the upper cover group 400 has an upper cover 43 pivotally connected to the cylinder body 23 in a manner that can be lifted, and a water guiding seat 44 provided on the upper cover 43. In this embodiment, the upper cover 43 has a pivoting part 431 pivotally connected to the annular part 233 in a rotatable manner, and a notch 432 opposite to the pivoting part 431 and in a fan shape.

[0046] The water guiding seat 44 is shaped to fit the notch 432 and is fixed in the notch 432. The lower half of the water guiding seat 44 extends into the water collecting chamber 241 and has a seat body 441 and a filter element 442 detachably installed on the seat body 441. The seat body 441 has a water guiding hole 443 fluidly communicating with the outside and the opening 242 of the water collecting box 24, a water guiding inclined surface 444 adjacent to the water guiding hole 443, and a hollow part 445 located below the water guiding hole 443. The water guiding hole 443 is lower than the ground 9 (see Figure 6 ) and is located above the water collecting chamber 241 and is spatially connected to the water collecting chamber 241. The water guiding hole 443 is semi-elliptical and has an area larger than the area of the opening 242 of the water collecting box 24. The water guiding inclined surface 444 extends obliquely downward from the outer edge of the water guiding seat 44 toward the water guiding hole 443.

[0047] Refer to Figure 3 and Figure 6, a space is formed beside the hollow portion 445 and is in communication with the water guiding hole 443 and the side opening 446 of the water collecting chamber 241, and a water inlet slope 447 is located below the water guiding hole 443, inclining downward toward the water collecting chamber 241. The side opening 446 is formed beside the water inlet slope 447 away from the water guiding hole 443 and extends along the top-bottom direction Z. The water inlet slope 447 is connected to the water guiding slope 244 and forms a height difference in the top-bottom direction Z.

[0048] The filter element 442 is located between the water guiding hole 443 and the water collecting chamber 241. Specifically, the filter element 442 is installed between the side opening 446 and the water collecting chamber 241. In some embodiments, the filter element 442 is a filter screen and is detachably installed at the side opening 446.

[0049] Refer to Figure 3 , Figure 6 and Figure 7 , the nozzle group 25 has a nozzle head 251 installed in the opening 242 of the water collecting box 24 and standing upright above the water guiding hole 443, and a connecting pipe 252 connected to the bottom end of the nozzle head 251 and extending downward. The nozzle head 251 has a water spraying hole 253 exposed outside and a spraying surface 254 higher than the water spraying hole 253. In this embodiment, the spraying surface 254 is an arc approximately one-fourth of a circle when viewed from the side. The connecting pipe 252 is in fluid communication with the water spraying hole 253. When the nozzle group 25 is installed on the water collecting box 24, it is more convenient to assemble and fix by using the shape matching of the positioning block 243.

[0050] As Figure 6 shown, since the slope of the water guiding slope 444 of the water guiding seat 44 inclines downward from top to bottom, when external water such as rainwater flows along the water guiding slope 444 of the water guiding seat 44 to the water guiding hole 443, it can flow smoothly and is not easy to accumulate water. Then, most of the water will directly fall onto the water guiding slope 244 of the water collecting box 24, and a small part of the water will flow to the water guiding slope 244 along the slope of the positioning block 243. Then, the water flows downward through the water inlet slope 447 and flows toward the side opening 446, and finally flows into the water collecting chamber 241 after passing through the filter element 442. The filter element 442 can filter foreign matters to block foreign matters such as sludge, leaves, and gravel from entering the water collecting chamber 241. In other variations, the positioning block 243 can also be omitted from the water collecting box 24.

[0051] Since the filter element 442 is disposed at the side opening 446, when foreign objects are blocked by the filter element 442, the foreign objects will start to accumulate from the bottom side of the side opening 446, and the top end of the side opening 446 remains unobstructed. Therefore, it will not affect the water from flowing into the water collecting chamber 241, and thus the water flow is smooth.

[0052] Refer to Figure 5 and Figure 6 , the electronic component unit 6 is installed in the cylinder base unit 200, and includes a module box 61 located at the ring portion 233, a waterproof member 62 disposed between the module box 61 and the first chamber 236, and an imaging module 8 installed in the module box 61 and facing the window portion 245. The module box 61 is located above the first chamber 236. Since the imaging module 8 and all electronic components are placed in the module box 61, it has the function of waterproofing and moisture-proofing. The power unit 91 is also adapted to supply power to the electronic component unit 6. The waterproof member 62 is a waterproof rubber cover, which has a watertight function and can ensure that the first chamber 236 remains dry and prevent the power unit 91 from being affected by moisture.

[0053] In this embodiment, the imaging module 8 is used to photograph the vehicle license plate and has a lens 81 facing the window portion 245. In other variations, the imaging module 8 may be a projector or other optical device.

[0054] Refer to Figure 3 , Figure 4 and Figure 6 , the automatic drainage unit 7 is installed in the cylinder base unit 200 and is in fluid communication with the nozzle head 251. The automatic drainage unit 7 is used to automatically drain the water that has penetrated from the outside and / or flowed into the water collecting chamber 241 to the outside, and includes a driver 71 that can be driven by the power unit 91 and a water suction pipe 72 connecting the connecting pipe 252 of the nozzle group 25. The driver 71 can be a driving water pump, a water suction motor, a submersible motor or other types of motors as long as it can pump water. The water suction pipe 72 is in fluid communication with the driver 71 and extends along the top-bottom direction Z. By using the water suction pipe 72 to connect the connecting pipe 252, the water suction pipe 72 is in fluid communication with the water spray holes 253. In some variations, the automatic drainage unit 7 further includes a liquid level sensor (not shown in the figure) that can detect the water level in the water collecting chamber 241 to determine whether to activate the pumping function.

[0055] When there is accumulated water on the ground 9, the accumulated water will flow from top to bottom along the water guiding inclined surface 444 into the water collecting chamber 241, or may seep into the water collecting chamber 241 through the joints of each component. Driven by electricity through the driver 71, the water in the water collecting chamber 241 can be forcibly drained automatically to the outside through the water suction pipe 72 and the nozzle group 25. Therefore, there will be no accumulated water in front of the window portion 245, so the lens 81 can take normal pictures, ensuring the normal operation of the imaging module 8. More specifically, when draining water automatically, the water will be accelerated and ejected through the water spraying holes 253 (see Figure 7 ) of the nozzle head 251, and discharged towards the distance outside through the spraying surface 254.

[0056] Refer to Figure 2 and Figure 8 , in some embodiments, the upper cover group 400 can move relative to the barrel body 23 between an open position (such as Figure 8 ) that does not block the open end 231, and a closed position (such as Figure 2 ) that blocks the open end 231. As shown in Figure 8 , when the upper cover group 400 is in the open position, the upper cover group 400 is lifted to one side with the pivot portion 431 as the rotation center, and the open end 231 of the barrel base unit 200 is opened. At this time, the water collecting box 24 can be taken out from the barrel body 23 to facilitate the removal of sludge or foreign objects in the water collecting box 24. If necessary, the driver 71 or the nozzle group 25 can also be removed from the water collecting box 24 for cleaning or maintenance. At the same time, the filter element 442 can also be removed from the seat body 441 for cleaning or replacing with a new product.

[0057] In some variations, the upper cover 43 can be fixed to the barrel body 23 with screws without the pivot portion 431. Therefore, when the barrel base unit 200 is already installed on the ground 9, as long as the screws are loosened, the upper cover group 400 can be removed, and the water collecting box 24 and the filter element 442 can also be cleaned, which has the effect of convenient disassembly.

[0058] As shown in Figure 9 , if the power unit 91 has no power, the upper cover group 400 can be lifted to the open position, and after removing the module box 61 and the waterproof member 62 first, the power unit 91 can be replaced.

[0059] Refer to Figure 3 and Figure 9, in some embodiments, the water guide seat 44 can be detachably installed on the upper cover 43. Specifically, two card slots 433 communicating with the notch 432 are further formed on the upper cover 43. The water guide seat 44 further has two insertion plates 448 respectively formed thereon and capable of being inserted into the card slots 433, so that the water guide seat 44 can be detachably engaged with the notch 432 of the upper cover 43. Therefore, it is more convenient to clean the water guide seat 44 or replace the filter element 442. It can be understood that the water guide seat 44 and the upper cover 43 can also be integrally formed.

[0060] Referring to Figures 10 to 12 , a second embodiment of the embedded imaging device capable of automatic drainage according to the present invention is applicable to being embedded in the ground 9 (see Figure 16 ), and is externally connected to a power supply and used for photographing vehicle license plates. The embedded imaging device capable of automatic drainage includes a cylinder base unit 200, an electronic component unit 6, and an automatic drainage unit 7.

[0061] The cylinder base unit 200 includes a base 21, a cylinder body 22, a top seat group 301, and an upper cover group 4.

[0062] The cylinder body 22 is fixed on the base 21 along a top-bottom direction Z, and defines a water collecting chamber 20 with an open top. The cylinder body 22 can be made of metal, alloy or plastic, and has a wiring hole 221 extending from the water collecting chamber 20 to the outside. The wiring hole 221 allows a power cord (not shown in the figure) to penetrate from the outside into the water collecting chamber 20. In some variations, the cylinder body 22 can be formed by digging a hole in the ground 9, and the base 21 can be omitted as long as the water collecting chamber 20 can be formed.

[0063] Referring to Figure 10 , Figure 12 and Figure 13 , the top seat group 301 is covered on the top of the cylinder body 22 along the top-bottom direction Z, and generally closes the water collecting chamber 20. The top seat group 301 has an outer cylinder 31, an inner cylinder 3 installed at the top of the cylinder body 22 and located inside the outer cylinder 31, a filter element 32 installed inside the inner cylinder 3, and a junction box 33 installed inside the inner cylinder 3.

In this embodiment, the outer cylinder 31 is made of aluminum alloy and has an outer cylinder body 312 with a diameter larger than that of the cylinder body 22, and a lower flange 313 extending downward from the bottom side of the outer cylinder body 312 and surrounding the cylinder body 22.

[0064] Referring to Figure 12 , Figure 14 , Figure 15and Figure 16 The inner cylinder 3 is disposed through the accommodation hole 311 of the outer cylinder 31. The inner cylinder 3 has an inner cylinder body 34 that is snap - connected to the outer cylinder body 312 and penetrates through the cylinder body 22, an inner cylinder base 35 that is snap - fitted to the inner cylinder body 34 from bottom to top, a abutting rubber pad 36 that abuts against the inner cylinder body 34 from top to bottom, a nozzle group 37 that penetrates through and is fixed to the abutting rubber pad 36 from top to bottom, and a water inlet valve 38 that is detachably installed on the inner cylinder body 34.

[0065] Refer to Figure 13 、 Figure 14 、 Figure 16 and Figure 17 The inner cylinder body 34 has a water trough portion 341 recessed downward, a window portion 342 protruding upward and capable of transmitting light, two spaced - apart raised portions 343, a light - transmitting sheet 344 installed on the window portion 342, an inner ring wall 345 that circumferentially surrounds the outside of the water trough portion 341 and the window portion 342, and an outer ring wall 346 that circumferentially surrounds the outside of the inner ring wall 345. A ring groove 347 is defined jointly by the inner ring wall 345 and the outer ring wall 346. The cylinder body 22 penetrates into the accommodation hole 311 from the lower flange 313 of the outer cylinder 31 toward the outer cylinder body 312, and the top end of the cylinder body 22 is embedded between the lower flange 313 of the outer cylinder 31 and the outer ring wall 346 of the inner cylinder body 34.

[0066] The water trough portion 341 circumferentially defines a water trough 340 that is spatially connected to the collection chamber 20. The water trough portion 341 further has a water inlet hole 3411 that is spatially connected to the water trough 340 and the collection chamber 20, an opening 3412 that is spaced from the water inlet hole 3411 and is spatially connected to the water trough 340 and the collection chamber 20, and an inclined arc surface 3413 that gradually expands outward from the top side of the water trough 340. The inclined arc surface 3413 is, for example but not limited to, a sector. The window portion 342 is located at the top in the top - bottom direction Z and circumferentially defines a chamber 3420, and has a through - hole 3421 that is spatially connected to the chamber 3420 and is adjacent to and higher than the water trough 340. Most of the through - holes 3421 are lower than the ground 9 in the top - bottom direction Z. Each of the raised portions 343 protrudes upward and is hollow inside. The light - transmitting sheet 344 is installed on the through - hole 3421, and the light - transmitting sheet 344 is made of glass and has the functions of transmitting light and preventing water.

[0067] Refer to Figure 14 、 Figure 17 and Figure 18, the inner cylinder base 35 has a base wall 351 with a circular outer contour, and a surrounding wall 352 that surrounds the base wall 351 and is embedded in the annular groove 347 of the inner cylinder body 34. The base wall 351 has a mounting groove 353 for the water tank portion 341 of the inner cylinder body 34 to pass through, and a groove portion 354 that extends into one of the raised portions 343 of the inner cylinder body 34 for mounting the junction box 33.

[0068] Refer to Figure 12 , Figure 13 , Figure 16 and Figure 19 , the abutting rubber pad 36 is made of rubber and is installed on the water tank portion 341 of the inner cylinder body 34 and abuts against the inclined arc surface 3413. The abutting rubber pad 36 has a through groove 361 that is spatially connected to the water tank 340, an outer conical surface 362 that abuts against the inclined arc surface 3413, and a water falling surface 363 that is located on a side of the through groove 361 opposite to the outer conical surface 362. The water falling surface 363 is adjacent to the light-transmitting sheet 344. Through the inclined design of the water falling surface 363, the water splashed onto the light-transmitting sheet 344 can be guided to flow in the direction of the through groove 361.

[0069] The nozzle group 37 is inserted through the through groove 361 of the abutting rubber pad 36 and extends into the water tank portion 341 of the inner cylinder body 34. The nozzle group 37 also abuts against the abutting rubber pad 36, and has a seat body 371, and a nozzle head 372 installed on the seat body 371 along the top-bottom direction Z. The seat body 371 and the abutting rubber pad 36 are fan-shaped structures with matching shapes. The seat body 371 has a concave arc surface 373 that is recessed downward, a water inlet hole 374 that penetrates downward from the concave arc surface 373 and is approximately aligned with the water inlet hole 3411 of the inner cylinder body 34, and a water outlet hole 375 that is adjacent to the water inlet hole 374 and penetrates downward from the concave arc surface 373 and is aligned with the opening 3412 of the inner cylinder body 34. In this embodiment, the upper half of the water inlet hole 374 and the upper half of the water outlet hole 375 are connected as a whole and are directly communicated with the outside. The water inlet hole 374 and the water outlet hole 375 are spatially connected to the water tank 340 of the water tank portion 341. The nozzle head 372 is fixed to the water outlet hole 375, and has a water spraying hole 376 that is spatially connected to the water tank 340 and the outside, and a spraying surface 377 that is higher than the water spraying hole 376 and the water outlet hole 375. The spraying surface 377 of this embodiment is an arc surface that is approximately a quarter circle.

[0070] The water inlet valve 38 is detachably installed in the water inlet hole 3411 of the inner cylinder 3, and has a valve port 381 that is spatially connected to the water tank 340 and the water collecting chamber 20.

[0071] The filter element 32 is installed in the water tank 340 of the inner cylinder 3. The filter element 32 of this embodiment is made of stainless steel, is cylindrical in shape, and is covered with mesh holes. The water inlet valve 38 is located below the filter element 32. Therefore, the filter element 32 can block sludge, leaves, gravel or foreign objects from entering the water inlet valve 38 and has the function of removing debris. The filter element 32 can be taken out for cleaning or replaced with a new one when it gets dirty.

[0072] Refer to Figure 10 , Figure 11 , Figure 15 and Figure 16 , the upper cover group 4 is located above the water collecting chamber 20 in the top-bottom direction Z and is fixed to the top side of the outer cylinder 31 by a plurality of bolts. The upper cover group 4 has a water guiding area 41 that is generally fan-shaped and used to receive water, and a non-water guiding area 42 that is higher than the water guiding area 41. The water guiding area 41 has a water guiding concave portion 411 and a water guiding hole 412 that is fluidly connected to the outside and is spatially connected to the water guiding concave portion 411. The water guiding concave portion 411 has a water guiding inclined surface 413 that extends obliquely downward from the outer edge toward the water guiding hole 412, and two side blocking surfaces 414 that are respectively connected to opposite sides of the water guiding inclined surface 413 and extend upward to connect to the non-water guiding area 42. The water guiding hole 412 is aligned with the nozzle head 372, and its outer contour fits the concave arc surface 373 of the nozzle group 37 and is connected to the concave arc surface 373. That is to say, the nozzle head 372 is fixed to the water outlet hole 375 and stands upright in the water guiding hole 412. The water guiding hole 412, the water inlet hole 374, the water outlet hole 375, the water tank 340, and the water inlet hole 3411 are spatially connected to each other. Therefore, when the accumulated water or rainwater from the outside flows into the water guiding hole 412 through the water guiding inclined surface 413, it will first pass through the filter element 32 located between the water guiding hole 412 and the water collecting chamber 20 to filter debris, and finally be concentrated in the water collecting chamber 20 through the water inlet valve 38 installed in the water inlet hole 3411.

[0073] In this embodiment, the water inflow can be changed by replacing the water inlet valve 38 with different valve port inner diameters.

[0074] This embodiment also provides a waterproof gasket 5 between the upper cover group 4 and the top seat group 301. The waterproof gasket 5 is made of rubber and uses its elasticity to increase the water tightness, so it has a waterproof function.

[0075] Refer to Figure 12 , Figure 16 and Figure 17, the electronic component unit 6 is installed on the cylinder base unit 200 and includes a control board 63 installed on the top base group 301 and an imaging module 8 adjacent to the window portion 342. The control board 63 is installed on the base wall 351 of the inner cylinder base 35 and is located within another raised portion 343 of the inner cylinder body 34. Specifically, the imaging module 8 is installed within the window portion 342 of the top base group 301 and faces the light-transmitting sheet 344. In this embodiment, the imaging module 8 is a camera and includes a lens 81 that faces the light-transmitting sheet 344 and is lower than the ground 9 in the top-bottom direction Z. The lens 81 is used to capture the vehicle license plate. In other variations, the imaging module 8 can be a projector or other optical device.

[0076] Refer to Figure 11 , Figure 15 , Figure 16 and Figure 18 , the automatic drainage unit 7 is installed on the cylinder body 22 and the top base group 301 and is used to automatically drain the water that seeps in from the outside and / or flows into the water collection chamber 20 outwards. The automatic drainage unit 7 includes a driver 71 housed in the water collection chamber 20 and electrically connected to the control board 63 (see Figure 17 ), a water suction pipe 72 that is fluidly connected to the driver 71 and generally extends upwards along the top-bottom direction Z, a wiring pipe 73 that is connected to the driver 71 and the junction box 33 along the top-bottom direction Z, and a liquid level sensing group 74 housed in the water collection chamber 20. The driver 71 can be a driving water pump or a pumping motor. The top end of the water suction pipe 72 passes through the filter element 32 and is connected to the nozzle head 372 and is fluidly connected to the water spraying holes 376. The inner diameter of the water spraying holes 376 is smaller than the inner diameter of the water suction pipe 72. The liquid level sensing group 74 is used to sense the water level in the water collection chamber 20 and is signal-connected to the driver 71 to control the start or stop of the driver 71. In some embodiments, the liquid level sensing group 74 can also control the driver 71 by electrically connecting to the control board 63. Since the electronic control method is a prior art and has various variations, and those skilled in the art can infer and expand the details based on the above description, no further elaboration will be provided. In this embodiment, the liquid level sensing group 74 has a low water level sensor 741 and a high water level sensor 742 that is higher than the low water level sensor 741.

[0077] In this embodiment, external power supply is adopted. Therefore, the external power cord passes through the wiring hole 221 and is electrically connected to the control board 63 inside the junction box 33 to provide power. The control board 63 is electrically connected to the driver 71 and the liquid level sensing group 74 to provide power. The junction box 33 is coated with waterproof glue and has a waterproof function. If battery power supply is used, the wiring hole 221 can be closed.

[0078] When the liquid level in the water collection chamber 20 is higher than the high water level sensor 742, the driver 71 will be started to pump the water in the water collection chamber 20 to the top of the water extraction pipe 72 and automatically discharge it outward. Since the inner diameter of the water spray hole 376 is smaller than that of the water extraction pipe 72, the flow rate of water will increase when it flows through the water spray hole 376 from the water extraction pipe 72. Therefore, it has a spraying effect and can discharge water far away. When the liquid level in the water collection chamber 20 is lower than the low water level sensor 741, the driver 71 is turned off and the drainage stops.

[0079] When the inner diameter of the valve port of the water inlet valve 38 is large, it has the advantage of a large water intake and is not easily blocked. When the inner diameter of the valve port of the water inlet valve 38 is small, the water intake is less than the drainage volume of the automatic drainage unit 7, which helps to extend the service life of the driver 71. The user can select the inner diameter of the valve port of the water inlet valve 38 according to the installation environment.

[0080] In this embodiment, the liquid level sensing group 74 detects the water level height and drives the driver 71 to perform automatic drainage. The water is forced to be discharged above the ground 9 through the nozzle head 372. In some variations, the liquid level sensing group 74 can also be integrated into the driver 71, or only one liquid level sensor is needed to achieve the function of detecting the water level.

[0081] In this embodiment, the driver 71 is started by electricity to force the water in the water collection chamber 20 to be discharged to the outside through the nozzle head 372, which also has the function of automatic drainage.

[0082] It should be particularly noted that the through hole 3421 of the window portion 342 in this embodiment is adjacent to and faces the nozzle group 37, and the nozzle head 372 is located directly below the water guiding hole 412. However, in other variations, the through hole 3421 of the window portion 342 can be far away from and face away from the nozzle group 37, or the nozzle head 372 and the water guiding hole 412 can be spaced apart in the horizontal direction. The position configurations of the window portion 342, the water guiding hole 412, and the nozzle group 37 can be adjusted according to actual needs.

[0083] Since most of the through holes 3421 of the inner cylinder body 34 and the lens 81 are lower than the ground 9, when there is accumulated water on the ground 9, the accumulated water can flow downward along the water guiding inclined surface 413 into the water collecting chamber 20, and may also seep into the water collecting chamber 20 through the joints of each component. The automatic drainage unit 7 of the present invention can automatically drain the water in the water collecting chamber 20, so there will be no accumulated water in front of the lens 81, and thus the lens 81 can take pictures normally.

[0084] In some embodiments, the upper cover group 4 can be designed as a closed cover without openings, and the upper cover group 4 can be glued and waterproofed to the top seat group 301, and the designs of the water guiding area 41, the water guiding hole 412 and the water inlet hole 3411 can be omitted. When the accumulated water accidentally seeps into the water collecting chamber 20 through the joints of each component, the water can still be automatically drained through the automatic drainage unit 7.

[0085] In summary, the embedded imaging device of the present invention that can automatically drain water can automatically force the water in the water collecting chamber outwards towards the outside through the driver 71, so it can automatically drain water from bottom to top and outwards, avoiding the problem of accumulated water, enabling the imaging module 8 to take pictures or project normally, and thus can indeed achieve the purpose of the present invention.

[0086] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope of the present invention.
