[0036] See Figures 1 to 5 An embodiment of the present application provides a film developing device 100 for developing film. The film developing device 100 includes a developing box 10, a film winding assembly 20, and an upper cover module 30.

[0037] The developing box 10 includes a box body 11 and a middle cover 12 disposed on the top of the box body 11. The box body 11 includes a accommodating area 111 for accommodating film and a rinsing area 112 for accommodating developing fluid. A film take-up assembly 20 includes a take-up member 21 rotatably disposed within the rinsing area 112 and a knob 22 disposed on the outer wall of the box body 11. External force acting on the knob 22 drives the take-up member 21 to rotate, causing the film in the accommodating area 111 to be wound around the take-up member 21. The film can then rotate with the take-up member 21 to be developed in the rinsing area 112.

[0038] The upper cover module 30 includes a cover body 31, a bottom shell 32, and a motor 33. The cover body 31 is a trough-shaped structure with an open bottom. The bottom shell 32 is disposed at the bottom opening of the cover body 31 and, together with the cover body 31, forms an accommodating cavity 301. The motor 33 is disposed in the accommodating cavity 301. The cover body 31 is detachably connected to the top of the flushing box 10. The bottom shell 32 is disposed above the middle cover 12. The motor 33 can be connected to the film winding member 21 to drive the film winding member 21 to rotate.

[0039] The film developing device 100 of the present application includes a developing box 10, a film take-up assembly 20, and an upper cover module 30. The developing box 10 can accommodate film and developing liquid. The take-up member 21 of the film take-up assembly 20 is disposed within the box body 11. The film can be wound around the take-up member 21 and rotated as the take-up member 21 rotates to be developed in the developing liquid. A knob 22 is provided on the side of the box body 11 for operating the take-up member 21. The cover 31 of the upper cover module 30 is detachably mounted on the top of the developing box 10. A motor 33 in a housing 301 enclosed by the cover 31 and the bottom shell 32 can be connected to the take-up member 21 to drive the take-up member 21 to rotate.

[0040] In actual use, the user can manually rotate the film winding member 21 by turning the knob 22 according to their needs, or install the upper cover module 30 on the top of the developing box 10 to drive the film winding member 21 to rotate via the motor 33, thereby realizing automatic film winding and developing. The film developing device 100 of the present application has both a manual film developing mode and an automatic film developing mode. The user can select the corresponding developing mode to develop the film according to their needs, making the film developing more in line with the user's requirements and effectively realizing a diversified user experience.

[0041] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the developing box 10 includes a box body 11 and a middle cover 12. The box body 11 is open at the top and hollow inside. The interior space of the box body 11 forms a separate receiving area 111 and a developing area 112. The receiving area 111 is used to accommodate the film to be developed, and the developing area 112 is used to accommodate the developing solution used for developing the film.

[0042] In the processing box 10, the film to be processed is first placed in the accommodating area 111 of the box body 11. One end of the film can be pulled out through the top opening of the box body 11 and fixed to the film take-up member 21 in the processing area 112. The film in the accommodating area 111 can be fixed to the film take-up member 21 manually by the user, or by using a removable clamping member provided within the processing box 10 to transfer the end of the film to the film take-up member 21 in the processing area 112.

[0043] In some embodiments of the present application, the box body 11 is a rectangular parallelepiped structure as a whole, and the outer contour of the middle cover 12 is a rectangle. The middle cover 12 is arranged at the top opening of the box body 11.

[0044] In some examples, a gap is provided between one end of the middle cover 12 and the inner wall of the box body 11, and the gap between the end of the middle cover 12 and the inner wall of the box body 11 constitutes a liquid inlet 101, the position of the liquid inlet 101 corresponds to the flushing area 112 of the box body 11, and the liquid inlet 101 is connected to the flushing area 112 of the box body 11.

[0045] Through the liquid inlet 101, the user can directly pour the washing liquid into the washing area 112 of the box body 11 without opening the middle cover 12 or removing the middle cover 12 from the box body 11, making the operation more convenient and quick. In addition, during the film washing process, the user can also add washing liquid directly through the liquid inlet 101 at any time according to actual needs, avoiding the frequent opening and closing of the middle cover 12 that may affect the film washing operation.

[0046] In some examples, a liquid guiding surface 121 can be provided on the surface of the middle cover 12, and the liquid guiding surface 121 is arranged near the liquid inlet 101. The liquid guiding surface 121 is a sloped surface, which can prevent the flushing liquid from accumulating on the surface of the middle cover 12, thereby guiding the flushing liquid to the liquid inlet 101 and smoothly flowing into the flushing area 112 of the box body 11.

[0047] In this example, when the middle cover 12 is placed on the box body 11, a snap-fit groove 102 is formed between the side wall of the middle cover 12 and the inner wall of the box body 11. The snap-fit groove 102 is used to form a snap connection with the cover body 31 of the upper cover module 30 to achieve a detachable connection of the upper cover module 30 on the flushing box 10.

[0048] Furthermore, the film developing device 100 of the present application further includes a film winding assembly 20 , which includes a film winding member 21 and a knob 22 .

[0049] The film winding member 21 is arranged in the rinsing area 112 of the box body 11, and the knob 22 is arranged on the outer wall of the box body 11. The film winding member 21 includes a pair of oppositely arranged film cores 211, a rotating shaft connected between the two film cores 211, and a film winding gear arranged on the rotating shaft.

[0050] In some examples, the axial direction of the rotating shaft can be consistent with the width direction of the box body 11, or can be set to be consistent with the length direction of the box body 11, or can be set to be consistent with the height direction of the box body 11, or can even be set to be along other extension directions, which is related to the layout orientation of the various components inside the box body 11.

[0051] The axial direction of the rotating shaft shown in the drawings of this application is consistent with the width direction of the box body 11. This arrangement corresponds to the internal accommodating area 111 and the washing area 112 of the box body 11 being distributed along the length direction of the box body 11. It can not only ensure that the accommodating area 111 and the washing area 112 have corresponding appropriate capacity spaces, but also facilitate the miniaturization of the film washing device 100, making it convenient for users to carry and use.

[0052] In this example, a knob 22 is provided on the side wall of the box body 11, and the end of the knob 22 is connected to the shaft. The user rotates or twists the knob 22 to rotate the shaft, thereby rotating the film winding member 21 inside the box body 11, so that the user can manually develop the film.

[0053] A film winding gear is provided on the rotating shaft, and the film winding gear is used to be connected to the motor 33. The motor 33 can drive the film winding gear to rotate, thereby rotating the rotating shaft so that the film winding member 21 rotates inside the box body 11, realizing the operation of automatically washing the film by the film washing device 100.

[0054] Furthermore, the film developing device 100 further includes an upper cover module 30 , which includes a cover body 31 , a bottom shell 32 and a motor 33 .

[0055] See Figures 4 to 7 In some embodiments of the present application, the cover body 31 is a groove-shaped structure with an opening at the bottom, and the bottom shell 32 is arranged at the bottom opening of the cover body 31 and encloses the cover body 31 to form a receiving cavity 301.

[0056] In this embodiment, a funnel-shaped pouring groove 311 is provided on the top surface of the cover 31 , and a liquid outlet 314 is provided on the inner surface of the cover 31 corresponding to the pouring groove 311 . The liquid outlet 314 is communicated with the pouring groove 311 .

[0057] The upper cover module 30 is connected to the flushing box 10, and the liquid outlet 314 corresponds to the liquid guide surface 121 of the middle cover 12. The user can pour the flushing liquid through the pouring groove 311. The flushing liquid flows through the liquid outlet 314 to the liquid guide surface 121. The liquid is guided by the liquid guide surface 121 and enters the flushing area 112 of the box body 11 through the liquid inlet 101.

[0058] In some examples, a connection post 312 is protruded from the top inner wall of the cover 31 , and a connection hole 313 is formed on the connection post 312 . An assembly hole 322 is formed on the bottom shell 32 at a position corresponding to the connection post 312 .

[0059] The upper cover module 30 of this example also includes fasteners 34, which are inserted into the corresponding assembly holes 322 and connection holes 313 to securely connect the bottom shell 32 to the cover 31. The fasteners 34 can be screws or pins. The connecting posts 312 can form a support between the cover 31 and the bottom shell 32, creating a gap between the cover 31 and the bottom shell 32 to form the accommodating cavity 301.

[0060] The cover 31 is connected to the bottom shell 32, and the bottom end of the cover 31 extends outwardly beyond the peripheral side of the bottom shell 32. The bottom end of the cover 31 is detachably engaged with the engaging groove 102 formed between the middle cover 12 and the side wall of the box body 11, so that the cover 31 is detachably connected to the flushing box 10, thereby realizing a detachable connection between the upper cover module 30 and the flushing box 10.

[0061] Some examples, such as Figure 5 and Figure 6As shown, a fixing groove 113 is formed on the side wall of the box body 11 , and the fixing groove 113 is arranged corresponding to the clamping groove 102 .

[0062] The upper cover module 30 also includes a retaining block 35 movably mounted on the sidewall of the cover 31. The retaining block 35 is positioned near the bottom end of the cover 31. A transition opening 124 is provided in the middle cover 12. The retaining block 35 moves relative to the cover 31, either protruding from the sidewall of the cover 31 or retracting into the interior of the cover 31. When the cover 31 is removably attached to the flushing box 10, the retaining block 35 can extend into the interior of the box 11 through the transition opening 124. The portion of the retaining block 35 that protrudes from the sidewall of the cover 31 can be snapped into place and secured in the securing groove 113.

[0063] By engaging the locking block 35 with the fixing groove 113 , the upper cover module 30 can be stably connected to the developing box 10 , ensuring that the upper cover module 30 stably performs the function of automatically developing films.

[0064] In this example, the upper cover module 30 further includes an unlock button 361 movably disposed on a side wall of the cover body 31, and a spring 362 connected to the unlock button 361 and disposed inside the cover body 31. The latch block 35 is connected to the unlock button 361. The upper cover module 30 in this example may further include a connecting arm 363, one end of which is connected to the unlock button 361 and the other end of which is connected to the latch block 35.

[0065] External force presses the unlock button 361, and the spring 362 is elastically compressed, so that the block 35 retracts into the inside of the cover 31. When the external force is released, the spring 362 elastically extends, so that the block 35 protrudes from the side wall of the cover 31, thereby realizing the reset of the block 35.

[0066] When automatic film development is required, the upper cover module 30 is installed on the developing box 10, and the unlocking button 361 is pressed to retract the blocking block 35 into the inside of the cover body 31, and the bottom end of the cover body 31 is engaged with the engaging groove 102 formed between the middle cover 12 and the side wall of the box body 11, so that the upper cover module 30 is connected to the developing box 10. At this time, the external force on the unlocking button 361 is released, and the blocking block 35 is reset and engaged in the fixing groove 113.

[0067] When manual film washing is required, the upper cover module 30 can be removed from the washing box 10. Specifically, the unlocking button 361 can be pressed to disengage the block 35 from the fixing slot 113, and then the bottom end of the cover body 31 can be taken out of the engaging slot 102, thereby removing the upper cover module 30 from the washing box 10. The user can manually wash the film by turning the knob 22.

[0068] In some embodiments of the present application, a motor 33 is provided in the accommodating cavity 301 of the upper cover module 30 , and the upper cover module 30 further includes a driving gear 37 disposed in the accommodating cavity 301 .

[0069] The drive gear 37 is connected to the drive shaft of the motor 33, which drives the drive gear 37 to rotate. A through-hole 323 is provided on the bottom shell 32 at a position corresponding to the drive gear 37, and a through-hole 122 is provided on the middle cover 12. The edge of the drive gear 37 can extend through the through-hole 323. When the cover 31 is removably attached to the flushing box 10, the edge of the drive gear 37 extending from the through-hole 323 can enter the interior of the box body 11 through the through-hole 122 and connect with the film winding gear.

[0070] In this embodiment, the film winding assembly 20 may further include an intermediate gear disposed in the developing area 112 of the cassette body 11. The intermediate gear engages with both the drive gear 37 and the film winding gear. The drive gear 37 is connected to the film winding gear via the intermediate gear. The motor 33 drives the drive gear 37 to rotate, thereby driving the film winding gear to rotate, thereby rotating the shaft, thereby enabling the film developing device 100 to automatically develop the film.

[0071] In some examples, the upper cover module 30 further includes a battery 381, which is disposed in the accommodating cavity 301 and connected to the motor 33 to supply power to the motor 33. The bottom shell 32 is provided with an access opening 324 at a location corresponding to the location of the battery 381.
