DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-7 As shown, a fruit and vegetable scanning and identification device of the present invention includes a handle 1, the upper end of the handle 1 is fixedly connected to a support box 2, the inner bottom of the support box 2 is fixedly connected to a support base 21, a scanning camera 22 is provided on the front side of the support base 21, the upper end of the support base 21 is fixedly connected to a top plate 23, a transparent round cover 24 is rotatably connected between the top plate 23 and the support box 2, and the transparent round cover 24 is provided with a circle of saw teeth 25 on the inner lower part;

[0030] The lower end of the support base 21 is fixedly connected to a motor 3. The output end of the motor 3 passes through the support box 2 and is provided with a driving gear 31 that meshes with the saw teeth 25. A flap 32 is provided between the support box 2 and the top plate 23 and is located outside the transparent circular cover 24. A cleaning cloth 33 is provided on one side of the flap 32 to abut against the transparent circular cover 24.

[0031] The handle 1 has a built-in control motherboard, and a first button switch 34 and a second button switch 35 are provided on one side of the handle 1. The scanning camera 22, the motor 3, the first button switch 34 and the second button switch 35 are all electrically connected to the control motherboard. The lower end of the handle 1 is provided with a data cable 36 electrically connected to the control motherboard.

[0032] Before use, connect the data cable 36 to the electronic scale. When using, hold the handle 1, then face the scanning camera 22 towards the fruit to be weighed, and then press the first button 34. After pressing, the scanning camera 22 will scan the fruit through the transparent circular cover 24. The scanned data will be processed by the control motherboard and the corresponding price information will be transmitted to the electronic scale through the data cable 36. In this way, the scanning use of the fruit and vegetable scanning and identification device is completed;

[0033] Since the transparent circular cover 24 covers the outside of the camera 22, the transparent circular cover 24 can protect the camera 22, so that stains will only adhere to the outside of the transparent circular cover 24. When the transparent circular cover 24 is dirty, the user can press the second button switch 35. After pressing it, the control main board will control the output end of the motor 3 to rotate forward, so that it drives the driving gear 31 to rotate forward. When the driving gear 31 rotates forward, it will drive the transparent circular cover 24 to rotate forward through a plurality of saw teeth 25. At this time, the transparent circular cover 24 will rotate forward. When the transparent circular cover 24 rotates forward, since the cleaning cloth 33 on the flip plate 32 keeps in contact with the transparent circular cover 24, the outer side of the transparent circular cover 24 will be wiped clean by the cleaning cloth 33 during the forward rotation process, so that the transparent circular cover 24 can be automatically cleaned. This cleaning method is simple and convenient to operate, and does not require the user to wipe it manually, which is convenient for the user to use.

[0034] The flap 32 is rotatably connected between the top plate 23 and the support box 2 via a rotating rod 4. One end of the rotating rod 4 extends into the interior of the support box 2 and is provided with a driven gear 41 that meshes with the driving gear 31. The driven gear 41 includes an intermediate column 42 fixedly connected to the rotating rod 4. A gear ring 43 is rotatably connected between the upper and lower ends of the intermediate column 42 and is sleeved on the outside of the intermediate column 42. The gear ring 43 meshes with the driving gear 31. A plurality of first soft teeth 44 are evenly arranged on the inner side of the gear ring 43, and a plurality of second soft teeth 45 that mesh with the first soft teeth 44 are provided on the outer side of the intermediate column 42.

[0035] When the driving gear 31 drives the driven gear 41 to rotate, it actually drives the gear ring 43 to rotate. Since the inner wall of the gear ring 43 is meshed with the second soft teeth 45 on the outer wall of the intermediate column 42 through the first soft teeth 44, the gear ring 43 drives the intermediate column 42 to rotate when it rotates, and the intermediate column 42 drives the rotating rod 4 to rotate when it rotates. When the rotating rod 4 encounters resistance and cannot rotate, since the first soft teeth 44 and the second soft teeth 45 are both soft teeth, when the intermediate column 42 cannot rotate, the first soft teeth 44 and the second soft teeth 45 will deform relative to each other, allowing the soft teeth to sweep across each other. At this time, the gear ring 43 will rotate idly around the intermediate column 42. Therefore, when the rotating rod 4 encounters resistance and cannot rotate, the driven gear 41 will only drive the driven gear 41 to rotate idly, and will not drive the rotating rod 4 to rotate.

[0036] When the driving gear 31 rotates forward, it drives the driven gear 41 meshing with it to rotate in the reverse direction. At this time, the driven gear 41 drives the intermediate column 42 to rotate in the reverse direction, causing the cleaning cloth 33 on the inner side of the flap 32 to turn toward the transparent circular cover 24. In this way, the cleaning cloth 33 can maintain contact with the transparent circular cover 24.

[0037] A third button switch 52 is provided on one side of the handle 1, and the third button switch 52 is electrically connected to the control main board;

[0038] When the user presses the third button switch 52, the control motherboard will control the output end of the motor 3 to rotate in the reverse direction, so that it drives the driving gear 31 to rotate in the reverse direction. When the driving gear 31 rotates in the reverse direction, it will drive the driven gear 41 to rotate forward. When the driven gear 41 rotates forward, it will drive the rotating rod 4 to rotate forward, so that the rotating rod 4 drives the flip plate 32 to rotate forward, and the side of the flip plate 32 where the cleaning cloth 33 is set is turned outward. At this time, the user can contact the cleaning cloth 33, which makes it convenient for the user to clean the cleaning cloth 33.

[0039] The upper and lower ends of the intermediate column 42 are fixedly connected with ring pieces 5, and the upper ends of the gear ring 43 are provided with ring grooves 51 that match the ring pieces 5. There is a gap between the inner wall of the gear ring 43 and the outer wall of the intermediate column 42; the two ring pieces 5 are assembled in the two ring grooves 51 to enable the gear ring 43 and the intermediate column 42 to be rotatably connected. The gap between the gear ring 43 and the intermediate column 42 is used to set the first soft teeth 44 and the second soft teeth 45.

[0040] The first soft teeth 44 and the second soft teeth 45 are both made of elastic metal sheets or elastic rubber.

[0041] The cleaning cloth 33 is detachably fixedly connected to the flap 32. This connection allows the cleaning cloth 33 to be removed, making it easier for the user to clean the cleaning cloth 33.

[0042] A T-shaped slot 53 is formed on the side of the flap 32 away from the rotating rod 4. The T-shaped slot 53 extends through the side of the flap 32 facing the transparent circular cover 24. An elastic plastic plate 54 is assembled in the T-shaped slot 53. The cleaning cloth 33 is fixed to one side of the elastic plastic plate 54 and extends out of the T-shaped slot 53 to maintain contact with the transparent circular cover 24. Two upper and lower stoppers 541 are provided on the side of the T-shaped slot 53 away from the rotating rod 4.

[0043] In the initial state, the elastic plastic plate 54 is assembled in the T-shaped groove 53. The two limit blocks 541 can restrict the elastic plastic plate 54 to prevent the elastic plastic plate 54 from naturally escaping from the T-shaped groove 53, so that the cleaning cloth 33 and the flap 32 can be connected together.

[0044] If the elastic plastic plate 54 needs to be removed, the user can hold the elastic plastic plate 54 and pull it toward the larger opening side of the T-slot 53, causing the elastic plastic plate 54 to convexly deform, thereby disengaging the elastic plastic plate 54 from the T-slot 53. In this way, the cleaning cloth 33 can be removed from the flap 32. The steps for reinstalling the cleaning cloth 33 are the same as the above-mentioned disassembly steps and will not be repeated here.

[0045] A take-out slot 55 is provided on a side of the flap 32 away from the rotating rod 4 . The take-out slot 55 is provided to facilitate the user to hold the elastic plastic plate 54 and further facilitate the user to take out the elastic plastic plate 54 .

[0046] An anti-slip cover 56 is provided on the outside of the handle 1 . The anti-slip cover 56 can prevent the handle 1 from slipping off easily after the user holds it.

[0047] The scanning camera 22 is provided with fill lights 57 fixedly connected to the support base 21 on the upper and lower sides. The two fill lights 57 are electrically connected to the control main board. The fill lights 57 can fill light on the scanned fruit, so that the scanning camera 22 can scan a clear image.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
