It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0054] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. 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.

[0055] 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.

[0056] The present application provides a film developing device for developing films.

[0057] The specific embodiment of the film developing device of the present application is described in detail below with reference to the accompanying drawings.

[0058] Figure 1 is a side view of the film developing device in this embodiment, Figure 2 for Figure 1 Schematic diagram of the AA direction.

[0059] refer to Figure 1-2 The film developing device comprises a housing 1, a developing tank 2, a film core 3 and a driving member 4. The developing tank 2 is arranged inside the housing 1, and contains a liquid for developing the film. The film core 3 is rotatably arranged inside the developing tank 2, and the film core 3 is used to wind the film. The driving member 4 is arranged inside the housing 1, and the driving member 4 is used to drive the film core 3 to rotate, so as to drive the film to rotate in the liquid in the developing tank 2.

[0060] In the above-mentioned film developing device, a driving member 4 is provided to drive the film core 3 to rotate, so that the film core 3 can rotate automatically to wind the film. During the rotation of the film core 3, the film can be driven to rotate in the chemical solution in the developing tank 2, thereby realizing automatic film developing, improving the degree of automation of the film developing device, greatly reducing the difficulty of film developing operation, so that users with zero experience can perform film developing operations, and improving the user's convenience and experience.

[0061] In this embodiment, the housing 1 includes a shell 11 and a cover 12 .

[0062] One side of the housing 11 is open. The interior of the housing 11 has a storage space for storing film. Exemplarily, the top of the housing 11 is open.

[0063] The cover 12 is detachably connected to the shell 11 and is used to open and close the opening of the shell 11. When the cover 12 is connected to the shell 11 and closed at the opening of the shell 11, the cover 12 can shield external light and prevent external light from entering the accommodating space of the shell 11 through the opening, so as to ensure that the brightness of the accommodating space meets the environmental conditions required for film development. When the cover 12 is removed from the shell 11, the opening of the shell 11 allows the accommodating space to communicate with the outside, and the user can use the opening of the shell 11 as a medium for the accommodating space of the shell 11 to interact with the outside. For example, the user can put a film into or take it out of the accommodating space of the shell 11 through the opening of the shell 11.

[0064] The cover 12 is sealed to the shell 11, so that when the cover 12 is closed at the opening of the shell 11, it can prevent external light from entering the shell 11 through the gap between the cover 12 and the shell 11 and affecting the brightness of the accommodating space, thereby enhancing the light-proof ability of the outer shell 1 and ensuring that the brightness of the accommodating space meets the environmental conditions required for film developing.

[0065] Exemplarily, a limiting groove is provided on the shell 11, and a limiting platform matching the limiting groove is convexly provided on the cover body 12. When the cover body 12 is covered on the shell 11, the limiting platform engages with the limiting groove to achieve a sealed connection between the shell 11 and the cover body 12.

[0066] In other embodiments, a sealing ring may be provided between the connection between the shell 11 and the cover 12 to seal the gap between the shell 11 and the cover 12 , so as to achieve a sealed connection between the shell 11 and the cover 12 .

[0067] Figure 3 It is a schematic diagram of the partial structural decomposition of the film developing device in this embodiment.

[0068] refer to Figure 3In this embodiment, the cover body 12 includes a control cover 121 and a light shielding cover 122. The control cover 121 and the light shielding cover 122 are detachably connected, so that the control cover 121 and the light shielding cover 122 can be quickly assembled and disassembled.

[0069] The bottom of the control cover 121 is open. A display window 1211 is provided on the top wall of the control cover 121 .

[0070] The light shielding cover 122 can cover the bottom opening of the control cover 121 and enclose a receiving cavity with the control cover 121. When the cover body 12 is covered on the housing 11, the light shielding cover 122 can block external light, preventing the external light that penetrates into the receiving cavity from the display window 1211 from entering the housing 11 and affecting the brightness of the receiving space, thereby enhancing the light-proof capability of the housing 1 and ensuring that the brightness of the receiving space meets the environmental conditions required for film development.

[0071] refer to Figure 2 In this embodiment, the washing tank 2 is arranged inside the housing 1, and the washing tank 2 contains a liquid for washing the film. Specifically, the top of the washing tank 2 is open, so that the liquid can be contained therein. The opening of the washing tank 2 is in communication with the opening of the housing 11 and the accommodating space. In actual use, the film contacts the liquid inside the washing tank 2 to achieve film washing. In addition, the design of the top opening of the housing 11 makes it easy for the user to directly take out the washed film from the washing tank 2 through the opening of the housing 11 and the opening of the washing tank 2.

[0072] In this embodiment, the developing tank 2 and the housing 1 may be an integrated structure. When the film is being developed, the developing tank 2 and the housing 1 remain stationary and do not rotate.

[0073] In other embodiments, the washing tank 2 and the housing 1 can be detachably connected. When the washing tank 2 is connected to the housing 1, the washing tank 2 and the housing 1 remain stationary, and when the film is being washed, the washing tank 2 and the housing 1 do not rotate. In addition, the washing tank 2 can also be removed from the housing 1 to facilitate cleaning alone.

[0074] refer to Figure 2 The film core 3 is rotatably arranged inside the developing tank 2, and the film core 3 is used to wind the film. In actual application, one end of the film to be developed is connected and fixed to the film core 3. As the film core 3 rotates relative to the developing tank 2, the film core 3 will drag the film and wind the film. During the process of the film core 3 winding the film, the film wound on the outer layer of the film core 3 can contact the chemical solution in the developing tank 2, so that the film is developed.

[0075] The core 3 includes a first core 31 and a second core 32 which are arranged at intervals. The first core 31 and the second core 32 are arranged corresponding to the opposite side walls of the flushing tank 2. The first core 31 and the second core 32 are rotatably connected to the corresponding side walls of the flushing tank 2, and the first core 31 and the second core 32 rotate synchronously relative to the flushing tank 2. The first core 31 is provided with a plurality of first annular grooves, and the side wall of each first annular groove has a notch, which is used to achieve communication between two adjacent first annular grooves. The second core 32 is correspondingly provided with a plurality of second annular grooves, and the side wall of each second annular groove has a notch, which is used to achieve communication between two adjacent second annular grooves.

[0076] The interval between the first core 31 and the second core 32 can be set according to the width of the film to be installed.

[0077] In actual application, the two sides of one end of the film to be washed are first clamped in the first annular groove located in the middle of the first core 31 and the second annular groove located in the middle of the second core 32. As the first core 31 and the second core 32 rotate synchronously relative to the washing tank 2, the first core 31 and the second core 32 will drag the film, and make the film be wound outward along the middle of the first core 31 and the second core 32 in sequence and clamped in each first annular groove and the corresponding second annular groove. In this process, the film enters the first annular groove located in the outer layer through the gap of the first annular groove, and at the same time, the film enters the second annular groove located in the outer layer through the gap on the side wall of the second annular groove. In this way, the side walls of each first annular groove and the second annular groove can separate the washed and wound parts of the film on the core 3 to prevent the stacked films from contacting each other and causing the films to stick together, and even affecting the clarity of the pictures carried on the films, thereby improving the film imaging yield.

[0078] In this embodiment, the film core 3 is detachably connected to the developing tank 2. When the film developing device is used, the film core 3 can be connected to the developing tank 2, which is convenient and simple to operate. When the film developing device is not in use, the user can remove the film core 3 from the developing tank 2, so as to clean and maintain the film core 3 separately, and also to clean and maintain the developing tank 2, so as to facilitate the next use.

[0079] In this embodiment, the film developing device further includes a rotating member, which is provided through the developing tank 2 and the film core 3, and is used to realize a rotatable connection between the film core 3 and the developing tank 2. Specifically, the rotating member is provided through the developing tank 2, the first film core 31 and the second film core 32, so that the coaxial connection between the first film core 31 and the second film core 32 can be realized, and then the first film core 31 and the second film core 32 can be synchronously rotated relative to the developing tank 2.

[0080] Figure 4 Schematic diagram of the exploded structure of the rotating part in this embodiment.

[0081] refer to Figure 2 and Figure 4 The rotating member includes a first rotating shaft 51. The first rotating shaft 51 is disposed on the washing tank 2 and the film core 3, the first rotating shaft 51 is fixedly connected to the film core 3, and the first rotating shaft 51 is rotatably connected to the washing tank 2 to realize the rotatable connection between the film core 3 and the washing tank 2.

[0082] In other embodiments, the first rotating shaft 51 is detachably connected to the tablet core 3. When the first rotating shaft 51 is connected to the tablet core 3, the first rotating shaft 51 and the tablet core 3 remain relatively stationary and can rotate synchronously relative to the flushing tank 2. In addition, the tablet core 3 can be separated from the first rotating shaft 51 to facilitate maintenance, cleaning, or replacement.

[0083] In this embodiment, the first rotating shaft 51 is detachably connected to the flushing tank 2 , thereby realizing the detachable connection between the chip 3 and the flushing tank 2 .

[0084] In this embodiment, the first rotating shaft 51 is a hollow structure with a hollow interior, which can reduce the weight of the first rotating shaft 51 and facilitate the rotation of the first rotating shaft 51 relative to the flushing tank 2.

[0085] The rotating member may further include a second rotating shaft 52, which is connected to one end of the first rotating shaft 51, and the second rotating shaft 52 is coaxially arranged with the rotation axis of the first rotating shaft 51, and one end of the second rotating shaft 52 away from the first rotating shaft 51 is rotatably connected to the side wall of the housing 1. In actual use, the second rotating shaft 52 rotates synchronously with the first rotating shaft 51 to drive the tablet core 3 to rotate, and the first rotating shaft 51 and the second rotating shaft 52 cooperate to enhance the stability of the rotation of the tablet core 3.

[0086] In this embodiment, the second rotating shaft 52 is detachably connected to one end of the first rotating shaft 51, so that the second rotating shaft 52 can be removed from the first rotating shaft 51, thereby removing the obstruction of the second rotating shaft 52 to the first rotating shaft 51, and then facilitating the removal of the first rotating shaft 51 from the flushing tank 2.

[0087] Exemplarily, the second rotating shaft 52 is engaged with the first rotating shaft 51. Specifically, one axial end of the first rotating shaft 51 is opened to form a slot, and the second rotating shaft 52 passes through one of the side walls of the housing 1 and extends inward, and extends into the slot from the opening of the first rotating shaft 51, and is tightly combined with the inner wall of the first rotating shaft 51, so as to realize the engagement between the first rotating shaft 51 and the second rotating shaft 52, and thereby the first rotating shaft 51 and the second rotating shaft 52 are coaxially fixedly connected.

[0088] In other embodiments, one axial end of the second rotating shaft 52 may be opened to form a slot for engaging with the first rotating shaft 51 .

[0089] In some other embodiments, the second rotating shaft 52 and the first rotating shaft 51 may also be threadedly connected to achieve a detachable connection between the second rotating shaft 52 and the first rotating shaft 51 .

[0090] In this embodiment, the second rotating shaft 52 is detachably connected to the housing 1. Specifically, a perforation is provided on the side wall of the housing 1. In the process of installing the film developing device, after the film core 3 has been installed on the developing tank 2 through the first rotating shaft 51, the second rotating shaft 52 can be passed through the perforation and connected to the first rotating shaft 51, which is convenient and simple to operate. When the film developing device is in use, the second rotating shaft 52 can be removed from the first rotating shaft 51 and the housing 1 at the same time, so that the second rotating shaft 52 can be stored separately. In addition, the design of the detachable connection between the second rotating shaft 52 and the housing 1 and the first rotating shaft 51 makes it easy to replace the second rotating shaft 52 at any time when the second rotating shaft 52 is damaged.

[0091] Figure 5 FIG. 1 is a top view of the film developing device in this embodiment.

[0092] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The rotating member may further include a knob 53, which is fixedly connected to the second rotating shaft 52. The knob 53 is disposed in the housing 1 and is sealed with the housing 1. The knob 53 is used for the user to rotate to realize the rotation of the second rotating shaft 52. In this way, the user can manually operate the knob 53 to drive the second rotating shaft 52 to rotate. Therefore, the film developing device of this embodiment supports manual and automatic integration and can meet the diverse individual needs of users.

[0093] In this embodiment, the knob 53 includes a main body 531 and a limiting portion 532. One axial end of the main body 531 is open for the second rotating shaft 52 to pass through, and the main body 531 is coaxial with the second rotating shaft 52. The outer diameter of the main body 531 is adapted to the inner diameter of the through hole, so that the main body 531 can be inserted into the through hole. The limiting portion 532 is arranged around the outer circumference of the main body 531 and protrudes out of the main body 531 in the circumferential direction. The outer diameter of the limiting portion 532 is larger than the inner diameter of the through hole, and the limiting portion 532 is used to abut the side wall of the housing 1. When the main body 531 passes through the through hole, the limiting portion 532 can abut the side wall of the housing 1 to prevent external light from entering the interior of the housing 1 from the gap between the main body 531 and the through hole, so as to ensure that the brightness of the accommodating space of the housing 1 meets the environmental conditions for film washing.

[0094] The limiting portion 532 is located in the middle of the main body 531 along the axial direction, so that part of the main body 531 on one side of the limiting portion 532 can pass through the through hole, and part of the main body 531 on the other side of the limiting portion 532 is outside the shell 1 for manual operation by the user.

[0095] In other embodiments, the limiting portion 532 may also be connected to the axial end of the main body 531. When the main body 531 passes through the through hole, the limiting portion 532 can abut against the side wall of the outer shell 1, so that the limiting portion 532 is located outside the outer shell 1 and is used for manual operation by the user.

[0096] In some other embodiments, the knob 53 may also include only the main body 531. Specifically, the outer diameter of the second shaft 52 is matched with the inner diameter of the through hole, and the outer diameter of the main body 531 is larger than the inner diameter of the through hole, so that when the second shaft 52 passes through the through hole, the main body 531 can abut against the side wall of the housing 1 to prevent external light from entering the housing 1 through the gap between the second shaft 52 and the through hole.

[0097] refer to Figure 1 , Figure 2 and Figure 4 In this embodiment, the rotating member may further include a mounting shaft 54, which is disposed in the housing 1. The mounting shaft 54 ​​is coaxially arranged with the rotation axis of the first rotating shaft 51, and the first rotating shaft 51 is rotatably connected to the mounting shaft 54. The mounting shaft 54 ​​and the second rotating shaft 52 are arranged at the two axial ends of the first rotating shaft 51, so that while the first rotating shaft 51 is rotatably connected to the washing tank 2, the first rotating shaft 51 can also be rotatably connected to the opposite side walls of the housing 1 through the mounting shaft 54 ​​and the second rotating shaft 52, which can enhance the stability of the rotation of the first rotating shaft 51, so as to enhance the stability of the rotation of the film core 3, thereby stably driving the film to rotate in the chemical solution in the washing tank 2, so that the film is fully in contact with the chemical solution, so that the washed film can be imaged evenly, and the film imaging yield is improved.

[0098] In this embodiment, the installation shaft 54 ​​is detachably connected to the first rotating shaft 51 , so that the installation shaft 54 ​​can be separated from the first rotating shaft 51 , so as to facilitate the subsequent removal of the first rotating shaft 51 from the flushing tank 2 .

[0099] The mounting shaft 54 ​​is detachably connected to the housing 1. Specifically, a through hole is provided on the side wall of the housing 1. In the process of installing the film developing device, after the film core 3 has been installed on the developing tank 2 through the first rotating shaft 51, the mounting shaft 54 ​​can be passed through the through hole and connected to the first rotating shaft 51, which is convenient and simple to operate. When the film developing device is in use, the mounting shaft 54 ​​can be removed from the first rotating shaft 51 and the housing 1 at the same time, so that the mounting shaft 54 ​​can be stored separately. In addition, the design of the mounting shaft 54 ​​being detachably connected to the housing 1 and the first rotating shaft 51 makes it easy to replace the mounting shaft 54 ​​at any time when the mounting shaft 54 ​​is damaged.

[0100] Exemplarily, the first rotating shaft 51 is engaged with the mounting shaft 54. Specifically, a connecting groove is provided on the first rotating shaft 51, and one axial end of the mounting shaft 54 ​​can be clamped in the connecting groove. Alternatively, a connecting groove is provided on the mounting shaft 54, and one axial end of the first rotating shaft 51 can be clamped in the connecting groove.

[0101] The mounting shaft 54 ​​is sealed and connected to the housing 1. Specifically, the mounting shaft 54 ​​includes a mounting portion 541 and a connecting portion 542 and a sealing portion 543 respectively arranged at two axial ends of the mounting portion 541. The connecting portion 542 is used for detachable connection with the first rotating shaft 51. The outer diameter of the mounting portion 541 is larger than the outer diameter of the connecting portion 542, and the outer diameter of the mounting portion 541 is adapted to the inner diameter of the through hole. The outer diameter of the sealing portion 543 is larger than the inner diameter of the through hole, so that when the connecting portion 542 and the mounting portion 541 both pass through the through hole, the sealing portion 543 can abut against the side wall of the housing 1, thereby preventing external light from entering the interior of the housing 1 from the gap between the mounting portion 541 and the through hole, so as to ensure that the brightness of the accommodating space of the housing 1 meets the environmental conditions for film washing.

[0102] In other embodiments, the installation shaft 54 ​​can omit the connection portion 542 and directly be rotatably connected to the first rotating shaft 51 through the installation portion 541, which can simplify the structure of the installation shaft 54 ​​and facilitate manufacturing. Alternatively, the installation seat can also omit the installation portion 541. In this case, the outer diameter of the connection portion 542 is adapted to the through hole to simplify the structure of the installation shaft 54.

[0103] refer to Figure 2 The driving member 4 is arranged inside the housing 1, and the driving member 4 is used to drive the core 3 to rotate, so as to drive the film to rotate in the liquid medicine in the washing tank 2. When using the film washing device, the user can choose to directly drive the core 3 to rotate through the driving member 4, so as to realize the automatic rotation of the core 3 and wind the film. During the rotation of the core 3, the film can be driven to rotate in the liquid medicine in the washing tank 2, thereby realizing the automatic washing of the film, improving the automation degree of the film washing device, greatly reducing the difficulty of film washing, so as to facilitate the operation of film washing by users with zero experience, and improving the convenience and experience of users. In addition, the user can also manually operate the knob 53 to drive the core 3 to rotate, so as to personally experience the process of the core 3 rotating and winding the film, and driving the film to be washed by the liquid medicine in the washing tank 2.

[0104] Exemplarily, the driving member 4 can be arranged on the cover body 12, and can be installed on the housing 11 together with the cover body 12, or can be detached from the housing 11 together with the cover body 12. In this embodiment, the driving member 4 is detachably arranged in the accommodating cavity, and is located on the top of the light shielding cover 122. Since the light shielding cover 122 and the control cover 121 are detachably connected, the light shielding cover 122 can be removed from the control cover 121 to expose the driving member 4, so as to facilitate the maintenance of the driving member 4; and the driving member 4 is detachably arranged on the control cover 121 or the light shielding cover 122, so as to facilitate the removal of the driving member 4 from the control cover 121 or the light shielding cover 122, and facilitate the maintenance, replacement and other operations of the driving member 4.

[0105] In other embodiments, the driving member 4 may also be disposed on the housing 11 .

[0112] In this embodiment, the transmission member 6 may further include a driven wheel 62, which is connected to the core 3 and arranged coaxially with the rotation axis of the core 3, and is transmission-connected to the driving wheel 61. The driving member 4 is used to drive the driving wheel 61 to rotate and drive the driven wheel 62 to rotate, so as to realize the rotation of the core 3.

[0113] The driving wheel 61 is located on the circumferential side of the driven wheel 62, and the driving wheel 61 is meshed and connected with the driven wheel 62. In this embodiment, the driving wheel 61 and the driven wheel 62 are gears. Among them, the rotation of the core 3 is achieved by driving the driving member 4 and the gear meshing transmission, which has high transmission reliability and high transmission efficiency, and can ensure that the transmission ratio is stable and unchanged, so that the rotation speed of the core 3 can be guaranteed, and the core 3 can be ensured to rotate stably.

Exemplarily, a positioning groove is formed on the driven wheel 62, the inner diameter of the positioning groove is matched with the outer diameter of the main body 531 of the knob 53, and the positioning groove is engaged with the main body 531 to achieve relative fixation between the driven wheel 62 and the second rotating shaft 52, so that the driven wheel 62 can drive the second rotating shaft 52 to rotate.

[0115] In other embodiments, the second rotating shaft 52 may be omitted, and one axial end of the first rotating shaft 51 may directly pass through the flushing tank 2 and be passed through the driven wheel 62, and be connected and fixed to the driven wheel 62, so that the driven wheel 62 can directly drive the first rotating shaft 51 to rotate.

[0116] In other embodiments, the driven wheel 62 can be omitted, and saw teeth matching the periphery of the driving wheel 61 can be directly set on the periphery of the first core 31 or the second core 32, so that the driving wheel 61 is located on the peripheral side of the first core 31 or the second core 32, and the first core 31 or the second core 32 is directly meshed and connected with the driving wheel 61, which can simplify the structure.

[0117] In other embodiments, the driving member 4 can also be directly connected to the core 3 to simplify the driving structure. That is, the output shaft of the driving member 4 can be directly connected to the first rotating shaft 51, and the output shaft of the driving member 4 is coaxially arranged with the rotation axis of the first rotating shaft 51. For example, the driving member 4 can replace the second rotating shaft 52 and the knob 53, or the driving member 4 can replace the installation shaft 54.

[0118] In this embodiment, the film developing device further includes a circuit board 7, which is disposed inside the housing 1. The circuit board 7 is electrically connected to the driving member 4 and is used to control the opening and closing of the driving member 4. Specifically, the circuit board 7 is disposed inside the cover 12. Since the driving member 4 is disposed inside the cover 12, the cables used to realize the electrical connection between the circuit board 7 and the driving member 4 can be saved.

[0119] In this embodiment, the circuit board 7 is arranged in the accommodating cavity, and the circuit board 7 is detachably connected to the control cover 121 or the light shielding cover 122. When the control cover 121 and the light shielding cover 122 are separated from each other, the circuit board 7 can be detached from the control cover 121 or the light shielding cover 122, thereby facilitating the inspection, replacement and other operations of the circuit board 7.

[0122] In this embodiment, the battery 8 is arranged in the accommodating cavity, and the battery 8 is detachably connected to the control cover 121 or the light shielding cover 122. When the control cover 121 and the light shielding cover 122 are separated from each other, the battery 8 can be detached from the control cover 121 or the light shielding cover 122, thereby facilitating the replacement of the battery 8.

[0123] In this embodiment, the battery 8 may be a dry cell battery 8 .

The temperature detector 10 is inserted into the light shielding cover 122 and protrudes downward from the light shielding cover 122. In this way, when the cover body 12 is closed on the shell 11, the temperature detector 10 can extend into the developing tank 2 to detect the temperature signal of the chemical solution in the developing tank 2 and transmit the temperature signal to the circuit board 7. The circuit board 7 can control the film developing time according to the temperature signal.
