[0031] The present invention will be further explained below with reference to specific embodiments.
[0032] like Figures 1-5 As shown, this embodiment provides a 3D foot scanner, including a foot measuring platform 3, a connecting rod 2 at the rear end of the foot measuring platform 3, handrails on both sides of the connecting rod 2, and a display screen 1 at the top of the connecting rod 2. The display screen 1 is an existing product and is used to control the scanning start and display foot scanning parameters. Scanning rods 7 are provided at the four corners of the upper side of the foot measuring platform 3. The scanning rods 7 are used for foot stepping scanning and data collection. A cleaning mechanism 4 is provided below the scanning rods 7 on the foot measuring platform 3. The cleaning mechanism 4 is used to remove foreign objects and dirt from the soles of the feet.
[0033] like Figures 2-5 As shown, in this embodiment, the cleaning mechanism 4 includes a slidably disposed cleaning shell 401. The bottom of the cleaning shell 401 is a detachable baffle. The top of the cleaning shell 401 is symmetrically and fixedly connected to two support plates 409 that match the shape of the human foot. The middle of the support plate 409 is composed of multiple spaced baffles. Two sets of induction motors 402 are symmetrically arranged inside the cleaning shell 401. Each set contains two induction motors 402 arranged front and back. The output end of each set of induction motors 402 is rotatably connected to a driving helical gear 405. A bracket sleeve 408 is rotatably connected to the outer side of the rotating shaft in the middle of the induction motor 402 and the driving helical gear 405. The bracket sleeve 408 is fixedly connected inside the cleaning shell 401. The side of the driving helical gear 405 is meshed with a horizontally rotating driven helical gear 406. The upper sides of the two driven helical gears 406 located on the side closer to the inside of the foot measuring platform 3 are fixedly connected to two first... The cleaning disc 403 has two second cleaning discs 404 fixedly connected to the upper side of the two driven helical gears 406 on the outer side via a rotating shaft. The upper side of the first cleaning disc 403 and the second cleaning disc 404 is funnel-shaped. The first cleaning disc 403, the second cleaning disc 404, and the rotating shaft and driven helical gears 406 on the lower side are provided with guide holes 407, which facilitate foreign objects to move towards the middle and leak downwards during operation, and are collected downwards through the guide holes 407. The upper side of the first cleaning disc 403 and the second cleaning disc 404 is provided with annular baffles to prevent foreign objects from contaminating the internal components of the device during operation. At the same time, multiple vertical soft brushes are evenly distributed on the upper surface of the first cleaning disc 403 and the second cleaning disc 404. These soft brushes extend out of the cleaning shell 401 through the support plate 409 on the upper side of the cleaning shell 401, thereby cleaning the user's feet. The first cleaning disc 403 and the second cleaning disc 404 rotate in the same direction. A bracket sleeve 408 is rotatably connected to the outer side of the shaft between the driven helical gear 406 and the first cleaning disc 403. The bracket sleeve 408 is fixedly connected inside the cleaning shell 401. Similarly, a bracket sleeve 408 is rotatably connected to the outer side of the shaft between the driven helical gear 406 and the second cleaning disc 404.
[0034] like Figures 6-7 As shown, a sensor 6 is provided on the front side wall of the foot measuring platform 3 corresponding to the cleaning mechanism 4. A square through hole 9 is provided on the side wall of the foot measuring platform 3. Two electric telescopic rods 5 are symmetrically fixedly connected to the two side walls of the foot measuring platform 3. The electric telescopic rods 5 are arranged along the sliding direction of the cleaning shell 401. A connecting block 8 is provided at the end of the telescopic rod of the electric telescopic rod 5. The connecting block 8 passes through the square through hole 9 and is symmetrically fixedly connected to both sides of the cleaning shell 401. Connecting grooves are provided on both sides of the cleaning shell 401 corresponding to the position of the connecting block. The sensor 6 cooperates with the electric telescopic rod 5 to drive the cleaning shell 401 to extend and return.
[0035] The working principle of the technical solution provided by this utility model is as follows:
[0036] When performing a foot scan, after the user stands in the designated position, the sensor 6 detects the user's leg and activates the electric telescopic rod 5 to extend outward through signal transmission and response. At the same time, the cleaning shell 401 is driven to extend outward along the square through hole 9 of the foot measuring platform 3 through the connecting block 8 at the end of the telescopic rod and slowly approach the user. After the cleaning shell 401 reaches the designated position, it stops moving and waits for the user to move.
[0037] After the cleaning shell 401 extends, the user steps onto the support plate 409 above it. Upon detecting pressure, the instrument activates the induction motor 402 inside the cleaning shell 401. The output of the induction motor 402 drives the active helical gear 405 to rotate clockwise, which in turn drives the driven helical gear 406 to rotate counter-clockwise. Simultaneously, the driven helical gear 406, via a rotating shaft, drives the first cleaning disc 403 and the second cleaning disc 404 to rotate counter-clockwise. This causes the brushes on the upper sides of the first and second cleaning discs 403 and 404 to rotate around the central guide hole 407, thus removing foreign objects from the user's feet. Under gravity, the foreign objects move towards the center through the surfaces of the first and second cleaning discs 403 and 404, and fall through the guide hole 407 to the bottom of the cleaning shell 401.
[0038] After the user has finished cleaning their feet, they step onto the designated position on the foot measuring platform 3. The scanning rod 7 is controlled by the display screen 1 to scan the feet, thereby obtaining the specific parameters of the feet. At this time, the sensor 6 transmits a reset signal to reset the electric telescopic rod 5. At the same time, the connecting block 8 at the end of the telescopic rod drives the cleaning shell 401 to reset inward along the square through hole 9 of the foot measuring platform 3, thereby realizing the overall reset of the cleaning shell 401.
[0039] After a period of use, the foreign matter collected inside the instrument needs to be removed. At this time, the bottom baffle of the cleaning shell 401 can be removed and cleaned for reuse.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
