[0002] After endoscopes are cleaned, disinfected, and dried, they need to be hung and stored in a storage cabinet. Currently, generally, the endoscopes are hung on a bracket, and the bracket is installed in the storage cabinet. When in use, the cabinet door is opened to take out the corresponding endoscope; or when the bracket is not fully filled with endoscopes, the cabinet door is opened to supplement the endoscopes. However, each time the cabinet door is opened, it will cause external air to directly enter the cabinet body, and there are a large number of microorganisms, dust, etc. in the air, which may all cause contamination of the endoscopes. Although some ultraviolet lamps can be set for irradiation currently, this can only achieve sterilization on the surface of the endoscopes, and the ultraviolet lamps cannot irradiate each endoscope evenly, so the sterilization effect is not ideal.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0034] See Figures 1-10, the endoscopic storage cabinet of this embodiment includes a cabinet body 110, a cabinet door 120, a back plate 130, an air curtain frame 140, an airway tube 150, a bracket 160, and an orifice plate 170. The interior of the cabinet body 110 is hollow and open on one side, and the open side of the cabinet body 110 is closed by the cabinet door 120. One side of the cabinet door 120 is hinged to the cabinet body, and the other side is fixedly assembled to the cabinet body 110 through a door lock. This is the prior art, and specifically, the relevant structures of the cabinet body and the cabinet door in the prior art can be directly adopted.

[0035] An air curtain frame 140 is installed on one side of the cabinet body 110 close to the cabinet door 120, and an orifice plate 170 is installed on the side far from the cabinet door 120. Several through holes 171 are provided on the orifice plate 170; several through blowing holes 142 are provided inside the air curtain frame 140, and a hollow air curtain channel 141 is provided inside the air curtain frame 140, and the air curtain channel 141 is communicated with the blowing holes 142.

[0036] The air curtain frame 140 is assembled with one end of the airway tube 150. The airway tube 150 is installed on the inner wall of the cabinet body 110, and the other end is communicated with the ventilation channel 3611 of the ventilation seat 360 through a hose 390; the interior of the airway tube 150 is a hollow airway 151, and the airway 151 communicates the air curtain channel 141 with the interior of the hose 390. The hose 390 is flexible and can move with the movement of the ventilation seat 360, so as to keep the ventilation channel 3611 communicated with the airway 151 through the hose 390.

[0037] See Figures 1-14 , the ventilation seat 360 is installed on the fan 370. A guide shaft 380 and a fan housing 330 are installed on the fan 370. The interior of the fan housing 330 is hollow and an impeller 340 is installed. The impeller 340 is installed on the impeller shaft 341, and the impeller shaft 341 is inserted into the fan motor 320. The fan motor 320 is installed on the fan housing 330, and after the fan motor 320 is started, it can drive the impeller 340 to rotate, so as to blow air towards one end of the ventilation seat 360.

[0038] A first air inlet groove 331 and a second air inlet groove 332 are respectively provided on the side surface of the fan housing 330, at the end far from the impeller 340. The first air inlet groove 331 and the second air inlet groove 332 are used to suck in air flow so as to be blown towards one end of the ventilation seat 360 under the action of the impeller.

[0039] A grille seat 350 is installed at one end of the fan housing 330 close to the ventilation seat 360. A plurality of grilles 351 are installed on the grille seat 350. A grille groove 352 is formed between two grilles 351, and the air flow blown by the impeller 340 blows out after passing through the grille groove 352.

[0040] A plurality of groove tubes 361 are provided on the ventilation base 360. An air passage groove 362 is formed between two groove tubes 361. In the initial state, the groove tubes 361 are aligned with the grille 351, and the air passage groove 362 is aligned with the grille groove 352, so that the airflow blown by the impeller blows towards the orifice plate 170, and then after uniform air distribution through 171, it blows towards the bracket 160.

[0041] A side tube 363 is further provided on the ventilation base 360. The inside of the side tube 363 is a hollow side tube cavity 3631, and a side tube block 3632 is provided on the outer wall of the side tube 363. The side tube block 3632 is slidably sleeved on the guide shaft 380 in the axial direction, and a ventilation spring 381 is sleeved between the inner wall of the fan 370 and the side tube block 3632 on the guide shaft 380. The ventilation spring 381 exerts an elastic force ( Figure 7 for the standard) to push the ventilation base 360 downward, so that the ventilation base 360 maintains the initial state.

[0042] A groove tube groove 3611 is provided on the groove tube 361. The groove tube groove 3611 is communicated with the side tube cavity 3631 and opens to the side facing the grille base 350. See Figure 7 , after the ventilation base 360 moves up in place, the groove tube groove 3611 is aligned with the grille groove 352, and the air passage groove 362 is aligned with the grille 351, so that most of the airflow blown by the impeller 340 blows into the groove tube groove 3611, then enters the side tube cavity 3631, then enters the air duct 151 along the hose 390, enters the air curtain channel 141 along the air duct 151, and finally blows out from the air blowing holes 142 to form an air curtain at the air curtain frame 140. This air curtain can effectively prevent external air from entering the cabinet 110, thereby reducing the probability of the inside of the cabinet being contaminated. At the same time, part of the airflow of the fan also blows towards the orifice plate 170, so as to maintain a positive pressure state inside the cabinet and further reduce the probability of external air entering the cabinet. Due to the blocking of the air curtain, the air inside the cabinet basically circulates between the cabinet and the fan, thereby reducing the amount of air that the fan needs to inhale from outside the cabinet.

[0043] The second air inlet groove 332 is communicated with one end of the filter 210. The filter 210 is installed on the back panel 130. The filter 210 includes a filter element 212 and grids 211 installed at both ends of the filter element. The filter element 212 is used to filter large particulate impurities in the air to reduce the probability of large particulate impurities contaminating the inside of the cabinet. When the air pressure inside the cabinet is low, the air outside the cabinet will be inhaled from the filter 210 to supplement the air pressure inside the cabinet.

[0044] See Figure 7, when the cabinet door is in the closed state, the ventilation seat 360 is in the initial state. At this time, the fan blows air in a cycle inside the cabinet body to ensure that the inner diameter is in a ventilated environment, thereby reducing the probability of microorganisms breeding. After the cabinet door is opened, the ventilation seat 360 moves up to the uppermost end and is in the ventilation state. At this time, most of the air flow of the fan blows out from the air blowing holes 142 to form an air curtain on the side of the cabinet body close to the cabinet door, so as to greatly reduce the probability of external air entering the cabinet body.

[0045] A connector 364 is also installed on the ventilation seat 360. The connector 364 is communicated with the side pipe cavity 3631. The hose 390 is assembled and fixed with the connector 364 to realize the communication between the side pipe cavity 3631 and the air duct 151.

[0046] See Figures 1-10 , Figures 15-16 , an ultraviolet lamp 610 is also installed on the inner wall of the cabinet body 110. After the ultraviolet lamp 610 is started, it emits ultraviolet light to irradiate the inside of the cabinet body for sterilization and disinfection.

[0047] One end of the bracket 160 is assembled with the cabinet body 110 in a circumferentially rotatable manner, and the other end is assembled with the shaft bracket 113 in a circumferentially rotatable manner. The shaft bracket 113 is installed on the cabinet body 110. A first hanging plate 161 and at least a second hanging plate 162 are installed on the bracket 160. The first hanging plate 161 is used for hanging the operation part of the endoscope. The light guide hose of the endoscope is clamped into the through groove of the second hanging plate 162 to keep the endoscope in a hanging state.

[0048] One end of the bracket 160 close to the shaft bracket 113 is connected to the connection end 451 of the spline shaft 450 through a connector 163. Splines are arranged on the circumferential direction of the spline shaft 450. And one end of the spline shaft 450 away from the connection end 451 is inserted into the shaft sleeve 440 and is axially slidable and non-rotatable relative to the circumferential direction with it; The shaft sleeve 440 is installed on the cabinet body 110 in a circumferentially rotatable and axially slidable manner. One end of the shaft sleeve 440 enters the inside of the cabinet body 110 and is assembled with the stop ring 441, and the other end is sleeved with a clutch spring 460, passes through the clutch frame 430 and is assembled and fixed with the clutch ring 442. The clutch frame 430 is circumferentially rotatable and non-axially movable relative to the shaft sleeve 440. The two ends of the clutch spring 460 are respectively pressed against the cabinet body 110 and the clutch frame 430 to apply an elastic force to the shaft sleeve 440 away from the spline shaft 450.

[0049] The clutch ring 442 is pressed against the clutch disc 312 for transmission. The clutch disc 213 is installed on the motor shaft 311, and the motor shaft 311 is inserted into the motor 310. After the motor 310 starts, it can drive the clutch disc 312 to rotate. The clutch disc 312 drives the clutch ring 442 to rotate through friction. The clutch ring 442 drives the spline shaft 450 to rotate through the bushing 440. The spline shaft 450 drives the bracket 160 to rotate, and the bracket 160 drives the suspended endoscope to rotate, so that the endoscope can be evenly irradiated by the ultraviolet light on both sides, and the disinfection effect of each endoscope can be greatly improved. In this embodiment, the ultraviolet lamp 610 can be started according to a certain cycle through a built-in program, or a button can be set outside the cabinet, and the button is triggered to start.

[0050] Roller shafts 470 are respectively installed on both sides of the clutch frame 430. Roller 471 is respectively and rotatably sleeved on each roller shaft 470. In the initial state (when the cabinet door is closed), the roller 471 is pressed against the flat surface 4232, so as to keep the clutch ring 442 and the clutch disc 312 in pressing transmission. When the cabinet door is opened, the roller 471 is in close contact with the inclined surface 4231, so that the clutch ring 442 is kept away from the clutch disc 312. At this time, the clutch disc 312 and the clutch ring 442 are not in contact for transmission. This design is mainly to facilitate the rotation of the bracket 160 to suspend or remove the endoscope when the cabinet door 120 is opened. Since a reduction motor is selected for the motor 310, it can only drive the bracket 160 to rotate slowly. When the bracket 160 is rotated manually, either the resistance is too large and it is inconvenient to use, or the bracket 160 cannot be rotated. Therefore, cutting off the transmission between the bracket 160 and the motor shaft after the cabinet door is opened will make it more convenient to use. After the cabinet door is closed, the bracket 160 resumes transmission with the motor shaft, so that the motor 310 drives the bracket 160 to rotate slowly for ultraviolet light irradiation. When the ultraviolet lamp is turned off, the motor 310 can stop running.

[0051] The flat surface 4232 and the inclined surface 4231 are both arranged on the switch frame 420. First frame plates 421 and second frame plates 422 are respectively arranged at both ends of the switch frame 420. The first frame plate 421 is assembled with one end of the switch shaft 410, and the other end of the switch shaft 410 passes through the second cabinet board 112 and is assembled with the push ring 411. When the cabinet door is closed, the push ring 411 is pressed against the cabinet door.

[0052] The second mounting plate 422 is axially slidably sleeved on the optical axis 540. Both ends of the optical axis 540 are respectively mounted on the first cabinet plate 111 and the shaft plate 114. The second cabinet plate 112, the first cabinet plate 111, and the shaft plate 114 are all mounted on the cabinet body. A switch spring 530 is sleeved on the portion of the optical axis 540 between the second mounting plate 422 and the first cabinet plate 111. The switch spring 530 applies an elastic force to the second mounting plate 422 to push it towards the second cabinet plate 112. When the cabinet door is opened, the switch spring 530 pushes the switch frame 420 towards the second cabinet plate 112 until it reaches the rightmost end ( Figure 15 for the standard). At this time, the inclined surface 4231 and the roller 471 are pressed tightly, so as to drive the bushing 440 to move downward against the elastic force of the clutch spring 460 ( Figure 4 for the standard). That is, it is regarded that the clutch ring 442 and the clutch disc 312 are separated and not in transmission. At this time, the push ring 411 is at the position farthest from the second cabinet plate 112. When the cabinet door 120 is closed, the cabinet door contacts and presses the push ring 411, thus pushing the push ring 411 to move, which also pushes the switch frame 420 and the switch shaft 410 towards the first cabinet plate 111 (compressing the switch spring 530). That is, the inclined surface 4231 gradually moves away from the roller, and the roller gradually moves upward and fits or presses against the flat surface. The clutch spring 460 drives the bushing to move upward ( Figure 4 for the standard) and then presses and drives with the clutch disc 312.

[0053] One end of the second mounting plate 422 is assembled with one end of the cable shaft 520. The other end of the cable shaft 520 passes through the first cabinet plate 111 and is assembled and fixed with one end of the 510. The cable 510 bypasses the guide wheel 511 and is respectively assembled and fixed with the ventilation base 360 of each fan. The guide wheel 511 is rotatably mounted on the cabinet body 110 through the guide wheel bracket 115. See Figure 7 . When the cabinet door is closed, the ventilation base 360 is at the bottommost position at this time, and the clutch disc and the clutch ring are pressed and in transmission. Once the cabinet door 120 is opened, the fan motor starts to blow out air, and the push ring 411, the switch shaft 410, and the switch frame 420 move in the direction away from the first cabinet plate 111 under the push of the switch spring 530. Thus, the ventilation base 360 is pulled up to the topmost position through the cable 510 to complete the ventilation switching. The air enters the air duct 151 and the air curtain channel 141 and then blows out from the air blowing holes 142 to form an air curtain, and the inclined surface 4231 and the roller 471 are pressed tightly, so as to drive the bushing to move downward and the clutch disc and the clutch ring are separated and not in transmission.

[0054] This design realizes the switching of the ventilation base 360 through the opening and closing of the cabinet door on the one hand, and also realizes the transmission switching of the clutch disc and the clutch ring on the other hand. At the same time, without electricity, it is realized by a pure structural method, which is durable, low-cost, easy to maintain, and can simplify the electrical system.
