These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] See also Figures 1 to 4 As shown, the camera film developing device according to the embodiment of the present invention includes a main body 100 and a rotary cutting assembly 200 , wherein the rotary cutting assembly 200 is connected to the main body 100 .

[0046] The rotary cutting assembly 200 includes a housing 210, a cutter knob 220, a transmission part 230 and a cutter 240. The housing 210 has an installation cavity 211 for installing the camera film 10. The housing 210 is provided with a support part 212 on one side of the installation cavity 211. The support part 212 is formed with a support plane. The film of the camera film 10 can enter the main body 100 through the support plane. The cutter knob 220 is rotatably arranged on the housing 210 and is located outside the housing 210. The transmission part 230 is connected to the cutter knob 220 and is located inside the housing 210. The cutter knob 220 can drive the transmission part 230 to rotate. The cutter 240 is connected to the transmission part 230. When the cutter knob 220 drives the transmission part 230 to rotate, the cutter 240 can follow the transmission part 230 to move toward the support plane and cut the film.

[0047] By providing the rotary cutting assembly 200, the developing device has the function of shearing the film so that the tail end of the film is separated from the reel, thereby eliminating the need for manual shearing. Since the film cutting work can be completed inside the developing device, there is no need to remove the film for shearing. This effectively avoids the phenomenon of partial exposure of the film when the film is removed and sheared.

[0048] In addition, the rotary cutting assembly 200 drives the transmission part 230 to rotate through the cutter knob 220, and then the transmission part 230 drives the cutter 240 to move to cut the film. Therefore, the user only needs to rotate the cutter knob 220 to complete the film cutting, and the operation method is simple and convenient for users to use. The camera film developing device of the present application is more convenient to use, which is conducive to improving the user experience.

[0049] The main body 100 is used for developing the camera film 10. Figure 2 As shown, the main body 100 may include an upper cover assembly 110 and a developing box body 120 , and the upper cover assembly 110 and the developing box body 120 are relatively connected to form a developing space for developing the camera film 10 .

[0050] In the present application, the method of developing the film in the main body 100 is not specifically limited. For example, a developing chamber 121 may be provided in the developing space, and the developing chamber 121 is used to contain developing liquid. A disc holder 122 is rotatably provided in the developing chamber 121. The camera film 10 enters the main body 100 through the rotary cutting assembly 200 and is successively wound on the disc holder 122. When the camera film 10 is completely wound on the disc holder 122, the film tail end is sheared by the rotary cutting assembly 200 to separate the film from the reel. Afterwards, when the disc holder 122 rotates in the developing chamber 121, the film can be evenly soaked in the developing liquid to achieve developing.

[0051] The entire flushing box body 120 may be made of opaque material. The flushing cavity 121 is disposed in the flushing box body 120. The flushing box body 120 may be provided with a flushing knob 124 for manually driving the disc device 122 to rotate.

[0052] like Figure 2 As shown, the upper cover assembly 110 may include a first cover body 111 and a second cover body 112, wherein the first cover body 111 is located below the second cover body 112. The first cover body 111 may be made of an opaque material, so that the first cover body 111 and the flushing box body 120 may form a flushing space in a dark environment.

[0053] There is an installation space between the second cover 112 and the first cover 111, in which functional components such as batteries, control circuit boards, and drive motors can be installed. The drive motor is used to electrically drive the disc drive 122 to rotate to achieve film washing. In this application, the method of driving the disc drive 122 to rotate by the drive motor is not specifically limited.

[0054] The second cover body 112 may be provided with a control panel and control buttons, etc. The control panel and control buttons are used to realize intelligent display and control of the flushing device.

[0055] The camera film developing device of the present application can be used for both electric and manual development. Users can choose electric or manual development according to actual needs. In particular, when the battery inside the device is out of power, the user can manually develop the film. Therefore, the camera film developing device of the present application is more convenient to use and can meet the user's needs in different scenarios.

[0056] In the present application, the rotary cutting assembly 200 is connected to 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 may be disposed between the upper cover assembly 110 and the flushing box body 120 and located outside the flushing space.

[0057] The peeling assembly 200 may be detachably connected to the main body 100. Specifically, the housing 210 of the peeling assembly 200 may be detachably connected to the flushing box body 120. When the housing 210 and the flushing box body 120 are connected in place, the upper cover assembly 110 is then placed over the housing 210 and the flushing box body 120.

[0058] 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 in the shape of a ladder, for example, it can be a one-stage ladder structure (L-shaped). For example, the flushing box body 120 is provided with a side wall 125 arranged vertically on one side close to the flushing space, and a bottom wall 126 vertically 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 the mounting position. As an example, the bottom wall 126 has a certain height from the bottom surface of the flushing box body 120.

[0059] See also Figure 2 and Figure 3 As shown, in one embodiment, 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 inserted into the connection slot 214, so that the housing 210 can be detachably connected to the main body 100, so that the peeling assembly 200 can be quickly detached as an integral module to form a film developing device with the main body 100. For example, the housing 210 is provided with a connection slot 214, and the developing box body 120 of the main body 100 is provided with a connection block 130 corresponding to the connection slot 214.

[0060] The connecting groove 214 may be a long strip groove. The long strip connecting groove 214 may be provided in two pieces. The two connecting grooves 214 may be arranged in parallel and spaced on the surface of the housing 210 opposite to the flushing box body 120. Accordingly, the connecting block 130 may be provided in two pieces. The two connecting blocks 130 may be arranged in parallel and spaced on the surface of the flushing box body 120 opposite to the housing 210. For example, the two connecting blocks 130 may be provided on the side wall 125 of the flushing box body 120 described above.

[0061] When the housing 210 needs to be connected to the flushing box body 120, the connection groove 214 of the housing 210 is aligned with the connection block 130 and slid in, so that the connection block 130 is completely snapped into the connection 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 play the role of supporting the peeling assembly 200 as a whole.

[0062] The cross-sectional shape of the connection block 130 may be L-shaped. Accordingly, the cross-sectional shape of the connection groove 214 may also be L-shaped.

[0063] It is understood that in other embodiments, the positions of the connection slot 214 and the connection block 130 may also be interchanged. That is, the connection slot 214 is disposed on the flushing box body 120 , and the connection block 130 is correspondingly disposed on the housing 210 .

[0064] 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 some other embodiments, the housing 210 can also be detachably connected to the flushing box body 120 by a magnetic structure, a screw structure, or a snap structure.

[0065] See also Figure 2 As shown, in one embodiment, 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 inserted into the locking groove 215 to keep the shell 210 fixed on the main body 100.

[0066] The locking portion 140 may 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 may be disposed below the bottom wall 126 of the flushing box body 120 described above, and a portion of the locking portion 140 protrudes upward from the bottom wall 126. The locking portion 140 may slide in a horizontal direction.

[0067] Correspondingly, the locking groove 215 can be provided at the bottom of the housing 210. The notch of the locking groove 215 is opened in the horizontal direction. When the peeling assembly 200 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 of the flushing box body 120 and slid in, so that the connecting block 130 is completely snapped into the connecting groove 214. Then the locking part 140 is moved toward the locking groove 215 and snapped into the locking groove 215, so that the housing 210 cannot be separated from the flushing box body 120 upwards, thereby ensuring the reliable connection between the housing 210 and the flushing box body 120.

[0068] See also Figure 7 As shown, in one embodiment, the locking portion 140 includes a lock hook 141 and an elastic member 142, the lock hook 141 abuts against the elastic member 142, and the lock hook 141 can be elastically clamped into 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 lock hook 141.

[0069] When the shell 210 is connected to the flushing box body 120, the locking hook 141 can be inserted 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 withdraw from the locking groove 215, and the shell 210 can slide relative to the flushing box body 120 and can be removed.

[0070] It is understood that in other embodiments, the elastic member 142 may be omitted. That is, the movement of the lock hook 141 may be manually operated. When the housing 210 is connected to the flushing box body 120, the lock hook 141 is manually moved to be inserted into the locking groove 215, and the housing 210 can be kept fixed on the flushing box body 120; when the housing 210 needs to be removed, the lock hook 141 is manually moved to be removed from the locking groove 215, and the housing 210 can slide relative to the flushing box body 120 and can be removed.

[0071] It can be understood that in other embodiments, the rotary cutting assembly 200 can 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.

[0072] like Figure 3 As shown, in one embodiment, 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 shape of the camera film 10.

[0073] See also Figures 5 to 7 , illustratively, the mounting cavity 211 has a substantially cylindrical shape. The interior of the mounting cavity 211 is hollow, and an opening for inserting the camera film 10 is formed in its circumferential sidewall. After the housing 210 is assembled to the developing box body 120, and the upper cover assembly 110 is then placed over the housing 210 and the developing box body 120, the upper cover assembly 110 can block the opening of the mounting cavity 211, ensuring that the camera film 10 is reliably installed in the mounting cavity 211.

[0074] For example, when the upper cover assembly 110 is disposed on the outer shell 210 and the developing box body 120 , the film can enter the main body 100 from the gap between the opening of the installation cavity 211 and the lower surface of the upper cover assembly 110 .

[0075] like Figure 3 As shown, the housing 210 is provided with a support portion 212 on one side of the mounting cavity 211, and the support portion 212 forms a support plane. The film of the camera film 10 can enter the main body 100 through the support plane. Specifically, the support portion 212 can be a support table provided on one side of the opening of the mounting cavity 211, and the upper surface of the support table is a support plane for supporting the film. In other embodiments, the support portion 212 can also be a through slot opened on the side wall of the housing 210, and the lower wall surface of the through slot is the support plane, and the camera film 10 can enter the main body 100 through the through slot.

[0076] Combination Figure 6 As shown, in the embodiment of the present application, the film of the camera film 10 can be pulled out from the gap between the opening of the mounting cavity 211 and the lower surface of the upper cover assembly 110, and enter the main body 100 through the support of the supporting plane.

[0077] Although not specifically described in the present application, it is understood that a guide plate 123 for guiding the film to be wound onto the disc device 122 may be provided in the main body 100, as shown in FIG. Figure 6 As shown in the example, the guide plate 123 mainly plays a guiding role, so that the film can be aligned with the disc device 122 for winding.

[0078] like Figure 3 As shown, the cutter knob 220 of the peeling assembly 200 is rotatably disposed on the housing 210 and is located outside the housing 210. The transmission part 230 of the peeling assembly 200 is connected to the cutter knob 220 and is located inside the housing 210, and the cutter knob 220 can drive the transmission part 230 to rotate.

[0079] Specifically, the housing 210 may be provided with a through hole for inserting the cutter knob 220. The cutter knob 220 is inserted into the through hole of the housing 210 and exposed outside the housing 210. Meanwhile, the transmission part 230 located in the housing 210 may be connected to the cutter knob 220. When the user rotates the cutter knob 220, the transmission part 230 can rotate synchronously with the cutter knob 220.

[0080] See also Figure 4 In one embodiment, the transmission part 230 may be a semicircular cylindrical structure. The transmission part 230 may be sleeved on the outer periphery of the installation cavity 211. Figure 7 As shown, in this example, the transmission part 230 of the semicircular cylinder structure can be coaxially arranged with the cylindrical installation cavity 211 mentioned above. When the user rotates the cutter knob 220, the transmission part 230 can rotate around the installation cavity 211 as the cutter knob 220 rotates.

[0081] like Figure 4 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.

[0082] Of course, in other embodiments, the cutter knob 220 and the transmission part 230 may be split structures, and the two may be relatively fixedly connected together by means of a snap connection, a screw fastening connection, or the like.

[0083] See also Figure 4 The peeling assembly 200 further includes a cutter 240 connected to the transmission part 230. When the cutter knob 220 drives the transmission part 230 to rotate, the cutter 240 can follow the transmission part 230 to move toward the supporting plane and cut the film.

[0084] Specifically, in one embodiment, the cutter knob 220 has an initial position. Figure 7As shown, the cutter knob 220 is in the initial position, and the cutter 240 is arranged perpendicular to the support plane. Therefore, when the user turns the cutter knob 220, the transmission part 230 rotates with the cutter knob 220, and then the transmission part 230 drives the cutter 240 to cut the film on the support plane perpendicularly, so that the cutter 240 can better cut the film and ensure a neat cut.

[0085] See also Figure 8 When the user turns the cutter knob 220 counterclockwise, the transmission part 230 rotates with the cutter knob 220, and then the transmission part 230 drives the cutter 240 to cut the film on the supporting plane from bottom to top. Thus, the tail end of the film can be separated from the reel, and then the user can carry out the film washing operation.

[0086] See also Figure 2 As shown, in one embodiment, an opening 213 for the cutter 240 to pass through is provided on one side of the support portion 212 close to the mounting cavity 211. In this embodiment, the cutter 240 can cut the film on the supporting plane through the opening 213 driven by the transmission portion 230. When the film needs to be cut, since the position of the cutter 240 is between the mounting cavity 211 and the support portion 212, the two sides of the film at the lower cutting position of the cutter 240 are supported by the mounting cavity 211 and the support portion 212 respectively. Therefore, the cutter 240 can cut the film quickly and accurately to ensure a neat cut.

[0087] See also Figure 7 In one embodiment, the cutter 240 is tangent to the outer peripheral surface of the transmission part 230. In this embodiment, the transmission part 230 is a semicircular cylindrical structure as described above. The cutter 240 is connected to the outer peripheral wall of the transmission part 230 and is tangent to the outer peripheral surface of the transmission part 230. By arranging the cutter 240 tangent to the outer peripheral surface of the transmission part 230, the rotational motion of the transmission part 230 can be better converted into the linear motion of the cutter 240, which is conducive to the cutter 240 to better cut the film and make the user's operation more labor-saving.

[0088] like Figure 3 As shown, a mounting seat may be provided on the outer peripheral wall of the transmission part 230, and a cutting knife groove may be provided on the mounting seat. The back of the cutting knife 240 may be tightly engaged in the cutting knife groove. By providing the mounting seat and the cutting knife groove, the cutting knife 240 may be easily installed and removed, thereby facilitating the replacement of the cutting knife 240.

[0089] In other embodiments, the cutter 240 may also be fixed to the transmission part 230 by screw connection.

[0090] See also Figure 7As shown, in one embodiment, an avoidance groove 113 is provided at a position where the upper cover assembly 110 is opposite to the cutter 240. By providing the avoidance groove 113, the upper cover assembly 110 can be ensured not to be damaged by the collision of the cutter 240, so that the service life of the whole machine is longer.

[0091] The use process of the camera film developing device of the present application is as follows:

[0092] Generally, the camera film 10 has a free end (head end) and a connection end (tail end), and the connection end is fixed on the reel. First, the camera film 10 is installed in the installation cavity 211, and then the head end of the film is pulled out through the opening of the installation cavity 211 and fixed to the disc holder 122 along the guide plate 123. Then, the upper cover assembly 110 is closed.
