[0048] The embodiment of the present invention provides an endoscope cleaning device for automatically cleaning an endoscope 10, specifically cleaning the inner pipeline of the endoscope 10, such as Figure 1 shown.

[0049] like Figure 2-4 As shown, the endoscope cleaning device of the embodiment of the present invention includes a shell 20, a brush, a rotating transceiver mechanism 30 and a propulsion mechanism 40; the rotating transceiver mechanism 30 is used to rotate and transmit and receive the brush, and the propulsion mechanism 40 is used to propel the brush forward and backward, and the two cooperate to realize the rotation of the brush during the forward or backward propulsion process.

[0050] The brush can be a cleaning brush currently used for manual cleaning, or a cleaning brush specially configured for automatic sending and receiving and rotation. The embodiment of the present invention does not limit the specific structure of the brush. Conventionally, the brush has a brush head and a brush body. During the cleaning process, the brush body drives the brush head forward, backward, and rotates, so that the brush head contacts the inner wall of the inner pipe of the endoscope 10 for cleaning.

[0051] Further, the housing 20 includes a bottom shell 21 and an upper cover 22, and the upper cover 22 is preferably connected to the bottom shell 21 in an openable-closable manner, for example, the bottom shell 21 and the upper cover 22 are connected by a hinge 23, so that the upper cover 22 can be closed when in use and opened when necessary to perform related operations, such as adding a solution for cleaning the brush and replacing the brush, etc. Accordingly, a controllable area such as a control button 24 can be provided on the upper cover 22 to directly operate the cleaning process.

[0052] like Figure 5-6 As shown, the rotating transceiver mechanism 30 is disposed on the bottom shell 21 in a detachable manner as a whole, and includes a winding mechanism 31 and a driving mechanism 32 .

[0053] The winding mechanism 31 is used to store the brushes in a wound manner, and includes a fixed bracket 311, a movable bracket 312 and a winding drum 313, on which the brushes are wound; preferably, a winding groove 3131 is provided on the outer periphery of the winding drum 313, in which the brushes are wound to accommodate more brushes; at the same time, the brushes will not fall off the winding drum 313.

[0054] The fixing bracket 311 is disposed on the bottom shell 21 to provide an installation space and a brush inlet and outlet channel 3111 for sending and receiving the brush, and the brush extends from the brush inlet and outlet channel 3111 to the downstream to perform a cleaning task.

[0055] The movable bracket 312 is rotatably disposed on the fixed bracket 311 and can rotate around a first direction; wherein the first direction is specifically a horizontal direction; preferably, the brush inlet and outlet channel 3111 is flush with the rotation centerline of the movable bracket 312 .

[0056] The winding drum 313 is arranged on the movable bracket 312 and can rotate around the second direction; the second direction is specifically a vertical direction, thereby forming an arrangement in which the first direction and the second direction are perpendicular to each other, so that the winding drum 313 can perform a compound motion in two directions, namely revolution and rotation.

[0057] The driving mechanism 32 in the embodiment of the present invention is used to drive the winding disk 313 to rotate around the second direction to send and receive the brush and to drive the movable bracket 312 to rotate around the first direction to rotate the brush;

[0058] like Figure 7-9 As shown, the driving mechanism 32 includes a first direction driving shaft 322 and a second direction driving shaft 323. The first direction driving shaft 322 is arranged on the housing 20 to drive the movable bracket 312 to rotate; the second direction driving shaft 323 is arranged on the movable bracket 312 to drive the winding reel 313 to rotate.

[0059] In order to maintain the tension of the brush during the sending and receiving process and avoid the problem of poor winding caused by too low brush tension, the driving mechanism 32 also includes a differential transmission component 325 for maintaining the tension state of the brush during the sending and receiving process. The second direction driving shaft 323 is connected to the winding drum 313 through the differential transmission component 325; please continue to refer to Figure 7-9 A specific structure of the differential transmission assembly 325 includes a support seat 3251, a first rotating body 3252, a second rotating body 3253 and a preload spring 3254.

[0060] The support base 3251 is disposed on the winding drum 313 to provide support and installation conditions;

[0061] The first rotating body 3252 is disposed on the second direction driving shaft 323 and can rotate synchronously with the second direction driving shaft 323; the second rotating body 3253 is disposed on the supporting seat 3251 and can rotate synchronously with the supporting seat 3251;

[0062] Among them, contact or abutment can be formed between the first rotating body 3252 and the second rotating body 3253, and under the action of the pre-tightening spring 3254, contact transmission is formed between the first rotating body 3252 and the second rotating body 3253; when the relative rotational force between the first rotating body 3252 and the second rotating body 3253 exceeds the friction force provided by the pre-tightening spring 3254, the first rotating body 3252 and the second rotating body 3253 can produce relative rotation.

[0063] Specifically, a first contact portion 3255 is provided on the first rotating body 3252, and a second contact portion 3256 is provided on the second rotating body 3253. Under the action of the preload spring 3254, abutment fit is formed between the first contact portion 3255 and the second contact portion 3256; preferably, the first contact portion 3255 and the second contact portion 3256 are both formed as an annular structure, that is, the first rotating body 3252 and the second rotating body 3253 are assembled in a partially nested manner, so that the contact portion and the second contact portion 3256 form a contact fit.

[0064] Specifically speaking, the propulsion speed of the brush in the propulsion mechanism 40 is set to a first speed, and the rotation speed of the winding drum 313 is set to a second speed; when the brush is propulsed forward, the first speed is greater than the second speed to maintain the tension of the brush during the sending out process, that is, when the brush is propulsed forward, the propulsion mechanism 40 always has a certain pulling force on the winding drum 313, so that even if the propulsion mechanism 40 has a short speed change during the forward conveying process, it will not affect the winding drum 313 to send out the brush; similarly, when the brush is propulsed backward, the first speed is less than the second speed to maintain the tension of the brush during the retraction process.

[0065] The differential transmission component 325 in the embodiment of the present invention can effectively eliminate the tension problem caused by the speed change when the external drive transports the brush. The differential transmission component 325 is used to eliminate the speed difference in the sending and receiving process, which is beneficial to the stability and effectiveness of the sending and receiving of the brush.

[0066] Furthermore, in an optional embodiment of the present invention, the differential transmission assembly 325 may also include an adjusting member 3257 for changing the preload force of the preload spring 3254; for example, the support seat 3251 has a threaded portion, the adjusting member 3257 is an adjusting nut, the preload spring 3254 is a straight spring, and the two ends of the preload spring 3254 respectively abut the adjusting nut and the second rotating body 3253, so that the force of the preload spring 3254 can be changed by adjusting the specific position of the adjusting nut, so as to achieve the adjustment of the friction force provided by the preload spring 3254.

[0067] The driving mechanism 32 in the embodiment of the present invention can use two power sources to respectively drive the movable bracket 312 to rotate around the first direction and drive the winding drum 313 to rotate around the second direction. The specific structural form will not be elaborated here; however, the driving method of the above two power sources has many disadvantages such as multiple power sources, inconvenient control operation, large installation space and difficult wiring; therefore, the embodiment of the present invention especially adopts a single power source to simultaneously rotate the movable bracket 312 around the first direction and the winding drum 313 around the second direction.

[0068] Please continue reading Figure 6-9 The driving mechanism 32 also includes a motor 321 and a transmission assembly 324 , and the transmission assembly 324 is used to transmit power between the first direction driving shaft 322 and the second direction driving shaft 323 .

[0069] The motor 321 is arranged on the shell 20, and the first direction driving shaft 322 is arranged at the output end of the motor 321; preferably, in order to save space, a bevel gear set for steering can be provided at the output end of the motor 321; under the forward and reverse drive of the motor 321, the first direction driving shaft 322 drives the movable bracket 312 to rotate to realize the self-rotation of the brush.

[0070] The movable bracket 312 has a main body 3121 and a connecting part 3122 that are connected to each other; the main body 3121 is bowl-shaped or plate-shaped to form a rotation support effect for at least the rotation of the winding reel 313; the connecting part 3122 is used to form an adaptive connection with the first direction driving shaft 322 and rotate with the first direction driving shaft 322.

[0071] The winding drum 313 is preferably columnar, and an inwardly recessed groove 3132 is formed on a side surface of the winding drum 313 close to the main body 3121 , and the groove 3132 provides installation space for the second direction driving shaft 323 and the transmission assembly 324 .

[0072] The power of the first direction driving shaft 322 is transmitted to the second direction driving shaft 323 via the transmission assembly 324, so that the winding drum 313 rotates to realize the active sending and receiving of the brush.

[0073] Further, the transmission assembly 324 includes a first gear 3241, a second gear 3242, a transmission connector 3243, a first bevel gear 3244 and a second bevel gear 3245;

[0074] The first gear 3241 and the second gear 3242 form a planetary gear structure; specifically, the first gear 3241 is disposed on the first direction driving shaft 322, and the second gear 3242 is disposed on the movable bracket 312 and meshes with the first gear 3241, so that the second gear 3242 revolves around the first gear 3241;

[0075] Among them, a limiting part 3123 is set on the connecting part 3122 of the movable bracket 312 corresponding to the first gear 3241 and the second gear 3242, and the limiting part 3123 provides a gear ring for the first gear 3241 and the second gear 3242 to revolve relative to each other, ensuring the effectiveness of the second gear 3242 revolving around the first gear 3241.

[0076] The transmission connecting member 3243 is, for example, a transmission shaft, and the second bevel gear 3245 is connected to the second gear 3242 through the transmission connecting member 3243 and rotates synchronously; the first bevel gear 3244 is arranged on the second direction driving shaft 323 and meshes with the second bevel gear 3245, so that the winding drum 313 rotates.

[0077] Furthermore, in order to improve the movement stability, a mounting seat 3124 is provided on the movable bracket 312 in the embodiment of the present invention, and the mounting seat 3124 is used to provide good support to the transmission connection member 3243 and the second direction driving shaft 323; specifically, the mounting seat 3124 is arranged at the center of the main body 3121, and the mounting seat 3124 has a first rotating connection portion 3125 and a second rotating connection portion 3126; the transmission connection member 3243 is cooperated with the first rotating connection portion 3125 to form a support, and the second direction driving shaft 323 is cooperated with the second rotating connection portion 3126 to form a support.

[0078] In the embodiment of the present invention, in the first stage of transmission, the planetary gear cooperation formed by the first gear 3241 and the second gear 3242 realizes the rotation of the movable bracket 312 around the first direction, that is, the revolution; in the second stage of transmission, the transmission cooperation formed by the first bevel gear 3244 and the second bevel gear 3245 is used to transmit motion and power, thereby realizing the rotation of the winding drum 313 around the second direction, that is, the rotation; in this way, the brush can realize sending and receiving and rotation at the same time, thereby improving the cleaning effect and cleaning efficiency of the brush on the internal pipeline of the endoscope 10.

[0079] The driving mechanism 32 in the embodiment of the present invention simulates and reproduces the actual cleaning process, and can realize the self-rotation of the brush during the sending and receiving process of the brush, which greatly improves the cleaning effect and cleaning efficiency of the brush on the internal pipeline of the endoscope 10.

[0080] The propulsion mechanism 40 is used to actively transport the brush forward and backward; it should be noted that although the rotating transceiver mechanism 30 can receive and send the brush, the receiving and sending here only involves retracting the brush to be wound around the winding drum 313 and loosening the brush on the winding drum 313 so that it can be output. The rotating transceiver mechanism 30 is not used as a power structure for actively transporting the brush.

[0081] The propulsion mechanism 40 of the embodiment of the present invention adopts a friction propulsion method. In other embodiments of the present invention, the propulsion mechanism 40 may also adopt a spiral propulsion method, a clamping propulsion method, etc. Figure 3-4 As shown in FIGS. 10-11 , the propulsion mechanism 40 of the embodiment of the present invention includes a base 41 , a conveying belt assembly 42 and a pressure wheel assembly 43 .

[0082] The base 41 is arranged on the shell 20 and provides installation space for the conveying belt assembly 42 and the pressure wheel assembly 43; wherein, a first channel 411 and a second channel 412 are relatively arranged on the base 41, and the first channel 411 corresponds to the brush entrance and exit channel 3111 to receive the brush conveyed from the fixed bracket 311; the second channel 412 and the first channel 411 are at the same height, and specifically, the two are arranged in the same line to facilitate active conveying of the brush.

[0083] like Fig.12 As shown, the conveying belt assembly 42 provides the power for conveying, and includes a conveying motor 421 , a driving conveying wheel 422 , a driven conveying wheel 423 and a conveying belt 424 .

[0084] The conveying motor 421 is arranged on the base 41. In order to save space, a bevel gear steering structure can be arranged at the output end of the conveying motor 421 to transmit power and torque; the active conveying wheel 422 is rotatably arranged on the base 41 through a bearing seat, and the driven conveying wheel 423 is rotatably arranged on the base 41 through other bearing seats, and the conveying belt 424 is sleeved on the active conveying wheel 422 and the driven conveying wheel 423; specifically, the conveying belt 424 is arranged between the first channel 411 and the second channel 412 and is flush in height, that is, the brush passes through the first channel 411 and is compressed and conveyed by the conveying belt 424 and the pressure wheel assembly 43, and then passes out from the second channel 412, so that the conveying stage of the brush between the first channel 411 and the second channel 412 is a linear conveying, which is conducive to maintaining the stability of the brush conveying.

[0085] Furthermore, the propulsion mechanism 40 of the embodiment of the present invention further includes a tensioning assembly 44, and the tensioning assembly 44 is used to tension the conveying belt 424 so that the conveying belt 424 has a stable conveying force; please continue to refer to Fig.12 The tensioning assembly 44 includes a tensioning wheel 441 and a tensioning rod 442. The tensioning rod 442 is lockably and loosely arranged on the base 41. The tensioning wheel 441 is arranged on the tensioning rod 442 and can be pressed against the conveying belt 424. The tensioning rod 442 is actively loosened to adjust its position, and the force of the tensioning wheel 441 on the conveying belt 424 is adjusted to adjust the tension of the conveying belt 424. The tensioning rod 442 is locked to maintain the force of the tensioning wheel 441 on the conveying belt 424, thereby achieving the tension adjustment of the conveying belt 424.

[0086] In order to detect whether there is a brush between the first channel 411 and the second channel 412, the propulsion mechanism 40 in the embodiment of the present invention further includes a detection mechanism 45; Figure 13-14 As shown, the detection mechanism 45 includes a detection block 451 arranged on the brush conveying path and a floating component 452 adapted to the position of the detection block 451. The detection block 451 is arranged on the brush conveying path through the floating component 452 to detect the brush. When the brush is conveyed normally, due to the interference between the brush and the detection block 451, the brush can push the detection block 451 to other positions to form an avoidance. It should be pointed out here that the force required to push the detection block 451 is relatively small and will not affect the conveying of the brush.

[0087] Please refer again Fig.14 , the detection block 451 is rotatably arranged on the detection gear 453 and can rotate along with the detection gear 453; the floating assembly 452 is a spring-type assembly, which includes a rack 4521 and a floating spring 4522 for limiting the left and right positions of the rack 4521, and the rack 4521 is meshed with the detection gear 453;

[0088] A guide rail 413 is provided on the base 41, and the rack 4521 can be freely slidably arranged on the guide rail 413; there are preferably two floating springs 4522, and floating springs 4522 are provided on opposite sides of the sliding direction of the rack 4521. The floating spring 4522 can keep the rack 4521 in an initial position in the absence of external force, that is, keep the detection gear 453 and the detection block 451 in the initial position. At this time, the detection block 451 is located on the conveying path of the brush; when the brush is conveyed, it will push the detection block 451 to rotate, and the detection block 451 drives the detection gear 453 to rotate, so that the rack 4521 produces a certain displacement and generates a force on the floating spring 4522.

[0089] The continuous conveying of the brush can always keep the detection block 451 in a non-initial position; accordingly, the detection mechanism 45 also includes a detection element 454, a trigger part 4523 on the rack 4521, and the position of the detection block 451 is detected by the relative position relationship between the trigger part 4523 and the detection element 454, so as to obtain whether there is a brush for conveying at present; for example, the trigger part 4523 is a protruding trigger block, the detection element 454 is a contact switch, the detection block 451 is in the initial position (that is, when the rack 4521 is in the middle position), and the detection element 454 is in abutment with the trigger block; when the detection block 451 is in a non-initial position (that is, when the rack 4521 is in a non-middle position), the detection element 454 is separated from the trigger block.

[0090] like Figure 15-18 As shown, the pressure wheel assembly 43 includes a support frame 431, a pressure plate 432 and a pressure wheel 433; the support frame 431 is arranged on the base 41 and is located above the conveying belt 424, and the pressure plate 432 is arranged on the support frame 431; the pressure wheel 433 is arranged on the pressure plate 432 and can be pressed on the conveying belt 424; wherein, the brush passes through the first channel 411 and is pressed and conveyed by the conveying belt 424 and the pressure wheel 433, and then passes out from the second channel 412.

[0091] Furthermore, at least one of the pressure wheel 433 and the conveying belt 424 can generate elastic deformation to provide sufficient friction force for the brush conveying process; for example, the conveying belt 424 is made of a rubber belt, and the pressure wheel 433 is made of a silicone rotating wheel.

[0092] Specifically, in the embodiment of the present invention, the number of the pressure wheel assemblies 43 can be multiple groups, for example, three groups distributed along the conveying direction of the conveyor belt 424, and the support frames 431 in the multiple groups of pressure wheel assemblies 43 are prefabricated as one or connected as one.
