[0035] See also Figures 1 to 5 A camera film 10 developing device includes a main body 100 and a rotary cutting assembly 200, wherein the rotary cutting assembly 200 is connected to the main body 100.

[0036] The rotary cutting assembly 200 includes a housing 210 and a cutter 240. The housing 210 defines a mounting cavity 211 for mounting the camera film 10. Initially, the camera film 10 is placed in the mounting cavity 211. The housing 210 has a lip 212 on one side of the mounting cavity 211. The inner sidewall 125 of the lip 212 extends to meet the mounting cavity 211. The cutter 240 is movably disposed within the housing 210. An opening 213 for the cutter 240 to pass through is defined on the side of the lip 212 proximate the mounting cavity 211. The cutter 240 can move toward the upper surface of the lip 212 to cut the film.

[0037] By providing the rotary cutting assembly 200, the camera film 10 developing device can shear the trailing end of the film 10 and separate it from the spool, eliminating the need for manual cutting. Because the film cutting process is performed within the camera film 10 developing device, there is no need to remove the film 10 for shearing, effectively preventing partial exposure of the film 10 when removing and shearing it.

[0038] In some embodiments, the rotary cutting assembly 200 may further include a cutter knob 220 and a transmission unit 230. The cutter knob 220 is rotatably mounted on and outside the housing 210. The transmission unit 230 is connected to the cutter knob 220 and located inside the housing 210. The cutter knob 220 can drive the transmission unit 230 to rotate. A cutter 240 is connected to the transmission unit 230. When the cutter knob 220 drives the transmission unit 230 to rotate, the cutter 240 can follow the transmission unit 230 and move toward the upper surface of the edge portion 212 to cut the film.

[0039] In some embodiments, the cutter knob 220 drives the transmission part 230 to rotate, thereby driving the cutter 240 to move and cut the film. Therefore, the user only needs to rotate the cutter knob 220 to complete the film cutting, which is simple and convenient for users to use.

[0040] In some embodiments, a support portion 250 is further provided at the opening 213. The support portion 250 protrudes from the upper surface of the edge portion 212. The support portion 250 forms a support surface that protrudes from the upper surface of the edge portion 212. The film in the camera film roll 10 can pass through the support surface and enter the main body 100. By providing the support portion 250 with a support surface higher than the upper surface of the edge portion 212, when the film is drawn, the film at the leading end of the film roll 10 is lifted upward by the protruding support portion 250, eventually passing over the top of the opening 213, preventing the film from extending into the opening 213. This makes it easier for the user to pull the film to be fed into the main body 100, thereby improving the user experience. The height of the support portion 250 protruding from the edge portion 212 can be determined based on actual conditions and is not limited here.

[0041] In some embodiments, the support portion 250 includes a base 251 and a stopper 252. The base 251 is disposed on the upper surface of the edge portion 212. The upper surface of the base 251 forms a support surface, thereby utilizing the height of the base 251 to allow the support surface to be elevated above the upper surface of the edge portion 212. The stopper 252 is connected to the bottom end of the base 251 and extends into the opening 213. The stopper 252 forms a cutter 240 slot between the inner sidewalls 125 of the edge portion 212 for the cutter 240 to pass through. The stopper 252 fills the space within the opening 213, preventing the film from extending into the opening 213 from the bottom side of the base 251. The stopper 252 can correspond to the width of the opening 213 to fit snugly within the opening 213. The base 251 and the stopper 252 can be elongated or flat.

[0042] In some embodiments, the support portion 250 and the cavity wall of the mounting cavity 211 are integrally structured. Specifically, the side wall 125 of the stop portion 252, which faces away from the edge portion 212, can extend to connect with the cavity wall of the mounting cavity 211. The two can be integrally formed to simplify the manufacturing process. At the same time, the film pulled out of the mounting cavity 211 first passes over the support surface, thereby preventing it from entering the space between the support portion 250 and the outer wall 125 of the mounting cavity 211.

[0043] In some embodiments, the peeling assembly 200 further includes a pressure rod 260. The pressure rod 260 is disposed on the housing 210 and is located above the support surface. A guide groove is formed between the pressure rod 260 and the support surface for the film in the camera film roll 10 to pass through. After the film is pulled out, it passes through the guide groove and enters the main body 100. The guide groove guides the film, allowing it to move along a prescribed path.

[0044] In some embodiments, the pressure rod 260 can be parallel to the base 251, and the distance between the two is greater than the thickness of the film, so that the film can pass smoothly through the guide groove. A plurality of pressure rods 260 can be arranged at intervals in the horizontal direction to better guide the film. In some embodiments, the main body 100 is used to develop the camera film 10. Figure 2 As shown, the main body 100 may include an upper cover 110 and a developing box body 120 . The upper cover 110 and the developing box body 120 are connected relative to each other to form a developing space for developing the camera film 10 .

[0045] In this application, the method for developing film within the main body 100 is not specifically limited. For example, a developing chamber 121 may be provided within the developing space, which is configured to contain developing solution. A film core 122 is rotatably disposed within the developing chamber 121. The camera film 10 enters the main body 100 through the rotary cutting assembly 200 and is sequentially wound onto the film core 122. When the camera film 10 is fully wound onto the film core 122, the rotary cutting assembly 200 shears the film's tail end, separating it from the film reel. Subsequently, the film core 122 rotates within the developing chamber 121, evenly soaking the film in the developing solution and achieving development.

[0046] The flushing box body 120 can be made of an opaque material. The flushing cavity 121 is arranged in the flushing box body 120. The flushing box body 120 can be provided with a flushing knob 124 for manually driving the core 122 to rotate.

[0047] like Figure 2 As shown, the upper cover can be made of opaque material, so that the upper cover and the flushing box body 120 can form a flushing space in a dark environment.

[0048] The camera film developing device of the present application can be used for both electric and manual development. Users can choose between electric and manual development based on their actual needs. In particular, when the device's internal battery is low, users can manually develop the film. Therefore, the camera film developing device of the present application is more convenient to use and can meet users' needs in various scenarios.

[0049] In the present application, the rotary cutting assembly 200 is provided on the main body 100, which is used to install the camera film 10 and to cut and separate the film tail from the reel. Figure 1 and Figure 2 As shown, the peeling assembly 200 can be disposed between the upper cover 110 and the flushing box body 120 and outside the flushing space.

[0050] The peeling assembly 200 can be detachably connected to the main body 100. Specifically, the housing 210 of the peeling assembly 200 is detachably connected to the flushing box body 120. After the housing 210 and the flushing box body 120 are connected in place, the upper cover 110 is placed over the housing 210 and the flushing box body 120.

[0051] like Figure 2As shown, the flushing box body 120 can be roughly rectangular. The flushing box body 120 is provided with a mounting position for mounting the peeling assembly 200. The mounting position is roughly stepped, for example, it can be a one-step structure (L-shaped). For example, the side of the flushing box body 120 close to the flushing space is provided with a vertically arranged side wall 125 and a bottom wall 126 perpendicularly connected to the bottom of the side wall 125. The bottom wall 126 and the side wall 125 can form a stepped mounting position. The peeling assembly 200 is detachably mounted in this mounting position. As an example, the bottom wall 126 is at a certain height from the bottom surface of the flushing box body 120.

[0052] See also Figure 2 and Figure 3 As shown, in some embodiments, a connection slot 214 is provided on one of the housing 210 and the main body 100, and a connection block 130 is correspondingly provided on the other of the housing 210 and the main body 100. The connection block 130 can be snapped into the connection slot 214, allowing the housing 210 to be detachably connected to the main body 100. As a result, the rotary cutting assembly 200 can be quickly removed from the main body 100 as an integral module to form a film developing device. For example, the housing 210 has a connection slot 214, and the developing box 120 of the main body 100 has a connection block 130 corresponding to the connection slot 214.

[0053] The connecting groove 214 can be an elongated groove. Two elongated connecting grooves 214 can be provided. The two connecting grooves 214 can be arranged in parallel and spaced apart on the surface of the housing 210 facing the flushing box body 120. Accordingly, two connecting blocks 130 can be provided. The two connecting blocks 130 can be arranged in parallel and spaced apart on the surface of the flushing box body 120 facing the housing 210. For example, the two connecting blocks 130 can be provided on the sidewall 125 of the flushing box body 120 described above.

[0054] When the housing 210 needs to be connected to the flushing box body 120, the connecting groove 214 of the housing 210 is aligned with the connecting block 130 and slid into the housing 210, so that the connecting block 130 is fully engaged with the connecting groove 214, thereby removably fixing the housing 210 to the flushing box body 120. At this time, the bottom of the housing 210 can abut against the bottom wall 126 of the flushing box body 120 mentioned above. The bottom wall 126 can serve to support the peeling assembly 200 as a whole.

[0055] The cross-sectional shape of the connecting block 130 may be L-shaped. Accordingly, the cross-sectional shape of the connecting groove 214 may also be L-shaped.

[0056] It is understood that in other embodiments, the positions of the connecting groove 214 and the connecting block 130 can also be interchanged. That is, the connecting groove 214 is provided on the flushing box body 120. The connecting block 130 is correspondingly provided on the housing 210.

[0057] In the embodiment of the present application, the housing 210 and the flushing box body 120 are detachably connected by the snap fit between the connecting block 130 and the connecting groove 214. However, the present application is not limited thereto, and in other embodiments, the housing 210 may be detachably connected to the flushing box body 120 by a magnetic structure, a screw structure, or a snap-fit ​​structure.

[0058] See also Figure 2 As shown, in some embodiments, a locking portion 140 is movably provided on the main body 100, and a locking groove 215 is provided on the shell 210 corresponding to the locking portion 140. When the shell 210 is connected to the main body 100, the locking portion 140 can be snapped into the locking groove 215, so that the shell 210 remains fixed on the main body 100.

[0059] The locking portion 140 can be slidably disposed at a position where the flushing box body 120 is opposite to the bottom of the housing 210. For example, the locking portion 140 can be disposed below the bottom wall 126 of the flushing box body 120, with a portion of the locking portion 140 protruding upward from the bottom wall 126. The locking portion 140 can slide in a horizontal direction.

[0060] Correspondingly, a locking groove 215 can be provided at the bottom of the housing 210. The notch of the locking groove 215 is horizontally extending. When the peeling assembly 200 needs to be connected to the flushing cartridge 120, the connecting groove 214 of the housing 210 is aligned with the connecting block 130 of the flushing cartridge 120 and slid in, so that the connecting block 130 is fully engaged with the connecting groove 214. The locking portion 140 is then moved toward the locking groove 215 and engaged therewith, thereby preventing the housing 210 from being disengaged upward from the flushing cartridge 120, thereby ensuring a secure connection between the housing 210 and the flushing cartridge 120.

[0061] See also Figure 3 As shown, in some embodiments, the locking portion 140 includes a locking hook 141 and an elastic member 142. The locking hook 141 abuts against the elastic member 142 and can be elastically engaged with the locking groove 215. The elastic member 142 can be a coil spring. One end of the coil spring abuts against the flushing box body 120, and the other end abuts against the locking hook 141.

[0062] When the shell 210 is connected to the flushing box body 120, the locking hook 141 can be locked into the locking groove 215 under the action of the elastic member 142, and the shell 210 can remain fixed on the flushing box body 120. When the shell 210 needs to be removed, the user presses the locking hook 141 to make it exit the locking groove 215, and the shell 210 can slide relative to the flushing box body 120 and can be removed.

[0063] In other embodiments, the elastic member 142 may be omitted. That is, the locking hook 141 may be manually moved. When the housing 210 is connected to the flushing cartridge body 120, the locking hook 141 is manually moved so that it engages the locking groove 215, thereby maintaining the housing 210 fixed to the flushing cartridge body 120. When the housing 210 needs to be removed, the locking hook 141 is manually moved so that it exits the locking groove 215, allowing the housing 210 to slide relative to the flushing cartridge body 120 and be removed.

[0064] In other embodiments, the peeling assembly 200 may also be fixedly connected to the main body 100, that is, the shell 210 and the flushing box body 120 are an integral structure and the two cannot be separated.

[0065] like Figure 3 As shown, in some embodiments, a mounting cavity 211 for mounting the camera film 10 is formed inside the housing 210. The mounting cavity 211 may have a shape that matches the outer shape of the camera film 10.

[0066] See also Figures 3 to 5 For example, the mounting cavity 211 has a generally cylindrical shape. The interior of the mounting cavity 211 is hollow, and its circumferential sidewalls define an opening for inserting the camera film 10. When the housing 210 is assembled with the developing cartridge 120 and the upper cover 110 is placed over the housing 210 and developing cartridge 120, the upper cover 110 blocks the opening of the mounting cavity 211, ensuring that the camera film 10 is securely installed within the mounting cavity 211.

[0067] For example, when the upper cover 110 is placed on the outer shell 210 and the developing box body 120 , the film can enter the main body 100 through the gap between the opening of the installation cavity 211 and the lower surface of the upper cover 110 .

[0068] Although not specifically described in this application, it is understood that a guide plate 123 for guiding the film to be wound onto the film core 122 may be provided in the main body 100. Figure 3 As shown in the example, the guide plate 123 mainly plays a guiding role, so that the film can be aligned with the core 122 for winding.

[0069] The housing 210 may be provided with a through hole for receiving the cutter knob 220. The cutter knob 220 is inserted into the through hole of the housing 210 and is exposed outside the housing 210. Furthermore, a transmission unit 230 located within the housing 210 may be connected to the cutter knob 220. When the user rotates the cutter knob 220, the transmission unit 230 rotates synchronously with the cutter knob 220.

[0070] See also Figure 5In one embodiment, the transmission part 230 may be at least partially a semicircular cylindrical structure. The transmission part 230 may be sleeved on the outer periphery of the installation cavity 211. Figure 3 As shown, in this example, the transmission part 230 of the semicircular cylindrical structure can be coaxially arranged with the cylindrical mounting cavity 211. When the user rotates the cutter knob 220, the transmission part 230 rotates around the mounting cavity 211 along with the cutter knob 220.

[0071] like Figure 2 As shown, for example, the cutter knob 220 and the transmission part 230 are an integral structure. The cutter knob 220 can be a cylindrical cutter knob 220. The cutter knob 220 and the transmission part 230 can be integrally injection molded.

[0072] Of course, in other embodiments, the cutter knob 220 and the transmission part 230 may be separate structures, and the two may be relatively fixedly connected together by means of a snap connection, a screw fastening connection, or the like.

[0073] See also Figure 5 When the user turns the cutter knob 220 counterclockwise, the transmission unit 230 rotates with the cutter knob 220, and the transmission unit 230 drives the cutter 240 to cut the film on the supporting surface from bottom to top. This separates the tail end of the film from the spool, and the user can then proceed with the film development operation.

[0074] like Figure 5 As shown, a mounting seat can be provided on the outer peripheral wall of the transmission portion 230, and the mounting seat can be provided with a mounting groove. The blade back of the cutter 240 can be tightly engaged in the mounting groove. The provision of the mounting seat and the mounting groove facilitates the installation and removal of the cutter 240, thereby facilitating the replacement of the cutter 240.

[0075] In other embodiments, the cutter 240 may also be fixed to the transmission portion 230 by screw connection.

[0076] The use process of the camera film developing device of this application is as follows:

[0077] Typically, the camera film roll 10 has a free end (the leading end) and a connecting end (the trailing end), which is secured to the spool. First, the camera film roll 10 is installed in the mounting cavity 211. The leading end of the film roll is then pulled out through the opening of the mounting cavity 211 and secured to the film core 122 along the support portion and guide plate 123. The top cover 110 is then replaced.

[0078] After the film is completely rolled onto the film core 122, the cutter knob 220 is rotated counterclockwise, and the cutter 240 cuts upward toward the film, separating the tail end of the film from the spool.

[0079] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.
