Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0042] Example 1

[0043] In a typical implementation of the present invention, Figure 1-Figure 4 As shown, a pressing drive device for endoscope leak detection and disinfection is proposed, including: a mounting seat, a linear driving mechanism, a negative suction button pressing column 12 and a water vapor button pressing column 13. Two linear driving mechanisms are provided, and the two linear driving mechanisms are fixedly mounted on the mounting seat, one linear driving mechanism is used to drive the negative suction button pressing column 12, and the other linear driving mechanism is used to drive the water vapor button pressing column 13, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 can perform pressing actions synchronously and independently and asynchronously (hereinafter described as step-by-step actions). It has strong applicability and can realize air and water supply and negative pressure suction work at the same time, saving time, being more efficient and convenient. In addition, the setting of the two linear driving mechanisms only requires forward movement to push the pressing column to move, reducing the need for backward movement, thereby saving installation space in the length direction and saving clinical space.

[0044] Specifically, in the present embodiment, each linear drive mechanism comprises a motor 4, a gear 5 and a rack 6. The mounting base is used to be fixedly connected to the shell of the automatic pretreatment equipment (i.e., endoscope leak detection and disinfection equipment). The mounting base comprises a substrate 1 and a bottom plate 2. The substrate 1 is U-shaped and vertically arranged. The bottom plate 2 is fixedly arranged at the bottom of the substrate 1. The bottom plate 2 is perpendicular to the substrate 1. The motors 4 of the two linear drive mechanisms are fixedly mounted on the bottom plate 2 through a motor fixing plate 3. The motor fixing plate 3 is parallel to the substrate 1. The two motors 4 are arranged up and down. Specifically, the two motors 4 are staggered up and down. A gear 5 is fixedly installed on the output end of each motor 4 to drive the rack 6 to perform linear reciprocating motion.

[0045] like Figure 2 As shown, the rack 6 is arranged horizontally and the two racks 6 are arranged opposite to each other up and down, and each rack 6 is meshed with a corresponding adjacent gear 5. Since the two motors 4 are staggered up and down, the two gears 5 are also staggered up and down. While saving vertical space, it can also avoid that one gear 5 is meshed with two racks 6 at the same time, thereby ensuring that one gear 5 meshes and drives one rack 6 correspondingly, thereby realizing independent driving of the two racks 6, so that the two racks 6 can move synchronously or in steps.

[0046] Each rack 6 is fixedly connected to a rack fixing plate 7, which is an L-shaped plate structure. The bending section of the rack fixing plate 7 is perpendicular to the linear movement direction of the rack 6. The rack 6 is fixedly installed on the inner side of the rack fixing plate 7, and the rack fixing plate 7 is slidably connected to the mounting seat through a linear guide slider module. Specifically, a slider 9 is fixedly installed on the top of each rack fixing plate 7, and a linear guide 8 is fixedly installed on the base plate 1 and the bottom plate 2 respectively. The linear guide 8 is parallel to the rack 6, and the two linear guides 8 are relatively distributed on the upper and lower sides of the two racks 6. The rack fixing plate 7 is slidably connected to the adjacent linear guide 8 through the slider 9, thereby guiding the movement of the rack 6 to avoid deviation during the linear motion of the rack 6.

[0047] The negative suction button pressing column 12 and the water vapor button pressing column 13 are both placed horizontally, and the negative suction button pressing column 12 and the water vapor button pressing column 13 are arranged relatively to each other up and down, and the negative suction button pressing column 12 and the water vapor button pressing column 13 are both slidably arranged in the guide sleeve 11, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 are guided by the guide sleeve 11 to avoid deviation of the negative suction button pressing column 12 and the water vapor button pressing column 13 when they are in action.

[0048] The guide sleeve 11 is made of self-lubricating material, and the inner hole of the guide sleeve 11 is slidably connected with the corresponding negative suction button pressing column 12 and the water gas button pressing column 13. The guide sleeve 11 is provided with an installation positioning hole so that it can be fixed on the housing of the automatic pretreatment equipment by screws.

[0049] It is understandable that in other embodiments, the guide sleeve 11 may not be provided, and other lubrication structures may be used, or the negative suction button pressing column 12 and the water vapor button pressing column 13 may be directly installed on the pretreatment equipment housing. The specific selection can be made according to actual design requirements, and no excessive restrictions are made here.

[0050] like Figure 2 As shown, a fixed gasket 10 is fixedly installed on one end of the negative suction button pressing column 12 and the water vapor button pressing column 13 near the bending section of the rack fixing plate 7, and a spring 15 is also respectively sleeved on the negative suction button pressing column 12 and the water vapor button pressing column 13, one end of the spring 15 is connected to the corresponding fixed gasket 10, and the other end of the spring 15 is connected to the guide sleeve 11, and the rack fixing plate 7 is in contact with the fixed gasket 10 through its bending section, thereby pushing the corresponding negative suction button pressing column 12 / water vapor button pressing column 13 to move in a straight line, and the spring 15 can drive the corresponding negative suction button pressing column 12 / water vapor button pressing column 13 to automatically reset when the rack fixing plate 7 is reset.

[0051] A flexible block 14 is fixedly provided on the end of the negative suction button pressing column 12 which is in contact with the negative suction button. The flexible block 14 contacts the negative suction button on the endoscope handle, which not only protects the surface of the endoscope button from damage, but also achieves sealed contact with the button surface, so that there is no gas leakage when the air supply action is performed.

[0052] It is understandable that the spring 15 and the fixed gasket 10 and the guide sleeve 11 can be fixedly connected or in abutting contact. The specific connection method can be selected according to actual needs and no excessive restrictions are made here.

[0053] In order to improve the control accuracy of the pressing stroke of the negative suction button pressing column 12 and the water vapor button pressing column 13, a first position sensor 16 and a second position sensor 17 are also provided. Figure 2 As shown, the first position sensor 16 is fixedly mounted on the upper part of the base plate 1, and the first position sensor 16 is close to the slider 9 on the upper linear guide 8, so as to monitor the moving distance of the slider 9 on the upper linear guide 8; the second position sensor 17 is fixedly mounted on the base plate 2, and the second position sensor 17 is close to the slider 9 on the lower linear guide 8, so as to monitor the moving distance of the slider 9 on the lower linear guide 8, so as to realize the accurate monitoring of the 0-point position, and ensure the accurate control of the pressing stroke of the negative pressure suction button and the air and water supply button each time.

[0054] It is understandable that the position sensor can be a limit travel switch, a photoelectric sensor or a magnetic induction sensor, etc. The specific type can be selected according to actual needs and no excessive restrictions are made here.

[0055] Example 2

[0056] In another typical implementation of the present invention, Figure 5-Figure 6 As shown, a pressing drive device for endoscope leak detection and disinfection is proposed, including: a mounting seat, a linear driving mechanism, a negative suction button pressing column 12 and a water vapor button pressing column 13. Two linear driving mechanisms are provided, and the two linear driving mechanisms are fixedly mounted on the mounting seat, one linear driving mechanism is used to drive the negative suction button pressing column 12, and the other linear driving mechanism is used to drive the water vapor button pressing column 13, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 can perform pressing actions synchronously and independently and asynchronously (hereinafter described as step-by-step actions). It has strong applicability and can realize air and water supply and negative pressure suction work at the same time, saving time, being more efficient and convenient. In addition, the setting of the two linear driving mechanisms only requires forward movement to push the pressing column to move, reducing the need for backward movement, thereby saving installation space in the length direction and saving clinical space.

[0057] Specifically, in the present embodiment, each linear drive mechanism comprises a motor 4, a gear 5 and a rack 6. The mounting base is used to be fixedly connected to the shell of the automatic pretreatment equipment (i.e., endoscope leak detection and disinfection equipment). The mounting base comprises a substrate 1 and a bottom plate 2. The substrate 1 is U-shaped and vertically arranged. The bottom plate 2 is fixedly arranged at the bottom of the substrate 1. The bottom plate 2 is perpendicular to the substrate 1. The motors 4 of the two linear drive mechanisms are fixedly mounted on the bottom plate 2 through a motor fixing plate 3. The motor fixing plate 3 is parallel to the substrate 1. The two motors 4 are staggered up and down. A gear 5 is fixedly mounted on the output end of each motor 4 to drive the rack 6 to perform linear reciprocating motion.

[0058] like Figure 5 As shown, the rack 6 is arranged horizontally and the two racks 6 are arranged opposite to each other up and down, and each rack 6 is meshed with a corresponding adjacent gear 5. Since the two motors 4 are staggered up and down, the two gears 5 are also staggered up and down. While saving vertical space, it can also avoid that one gear 5 is meshed with two racks 6 at the same time, thereby ensuring that one gear 5 meshes and drives one rack 6 correspondingly, thereby realizing independent driving of the two racks 6, so that the two racks 6 can move synchronously or in steps.

[0059] Each rack 6 is fixedly connected to a rack fixing plate 7, which is an L-shaped plate structure. The bending section of the rack fixing plate 7 is perpendicular to the linear movement direction of the rack 6. The rack 6 is fixedly installed on the inner side of the rack fixing plate 7, and the rack fixing plate 7 is slidably connected to the mounting seat through a linear guide slider module. Specifically, a slider 9 is fixedly installed on the top of each rack fixing plate 7, and a linear guide 8 is fixedly installed on the base plate 1 and the bottom plate 2 respectively. The linear guide 8 is parallel to the rack 6, and the two linear guides 8 are relatively distributed on the upper and lower sides of the two racks 6. The rack fixing plate 7 is slidably connected to the adjacent linear guide 8 through the slider 9, thereby guiding the movement of the rack 6 to avoid deviation during the linear motion of the rack 6.

[0060] The negative suction button pressing column 12 and the water vapor button pressing column 13 are both placed horizontally, and the negative suction button pressing column 12 and the water vapor button pressing column 13 are arranged relatively to each other up and down, and the negative suction button pressing column 12 and the water vapor button pressing column 13 are both slidably arranged in the guide sleeve 11, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 are guided by the guide sleeve 11 to avoid deviation of the negative suction button pressing column 12 and the water vapor button pressing column 13 when they are in action.

[0061] The guide sleeve 11 is made of self-lubricating material, and the inner hole of the guide sleeve 11 is slidably connected with the corresponding negative suction button pressing column 12 and the water gas button pressing column 13. The guide sleeve 11 is provided with an installation positioning hole so that it can be fixed on the housing of the automatic pretreatment equipment by screws.

[0062] It is understandable that in other embodiments, the guide sleeve 11 may not be provided, and other lubrication structures may be used, or the negative suction button pressing column 12 and the water vapor button pressing column 13 may be directly installed on the pretreatment equipment housing. The specific selection can be made according to actual design requirements, and no excessive restrictions are made here.

[0063] One end of the negative suction button pressing column 12 and the water vapor button pressing column 13 are respectively fixedly connected to the bending section of the adjacent rack fixing plate 7, so that the rack fixing plate 7 directly drives the corresponding negative suction button pressing column 12 and the water vapor button pressing column 13 to move back and forth. Figure 5 As shown, the negative suction button pressing column 12 is fixedly connected to the upper rack fixing plate 7, and the water vapor button pressing column 13 is fixedly connected to the lower rack fixing plate 7. The spring 15 and the fixing gasket 10 in Example 1 are omitted, which saves costs and improves the compactness of the structure. At the same time, the rack fixing plate 7 is directly fixedly connected to the negative suction button pressing column 12 and the water vapor button pressing column 13, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 can be driven to move more quickly and accurately.

[0064] A flexible block 14 is fixedly provided on the end of the negative suction button pressing column 12 which is in contact with the negative suction button. The flexible block 14 contacts the negative suction button on the endoscope handle, which not only protects the surface of the endoscope button from damage, but also achieves sealed contact with the button surface, so that there is no gas leakage when the air supply action is performed.

[0065] In order to improve the control accuracy of the pressing stroke of the negative suction button pressing column 12 and the water vapor button pressing column 13, a first position sensor 16 and a second position sensor 17 are also provided. Figure 5 As shown, the first position sensor 16 is fixedly mounted on the upper part of the base plate 1, and the first position sensor 16 is close to the slider 9 on the upper linear guide 8, so as to monitor the moving distance of the slider 9 on the upper linear guide 8; the second position sensor 17 is fixedly mounted on the base plate 2, and the second position sensor 17 is close to the slider 9 on the lower linear guide 8, so as to monitor the moving distance of the slider 9 on the lower linear guide 8, so as to realize the accurate monitoring of the 0-point position, and ensure the accurate control of the pressing stroke of the negative pressure suction button and the air and water supply button each time.

[0066] It is understandable that the position sensor can be a limit travel switch, a photoelectric sensor or a magnetic induction sensor, etc. The specific type can be selected according to actual needs and no excessive restrictions are made here.

[0067] Example 3

[0068] In another typical implementation of the present invention, Figure 7-Figure 9 As shown, a pressing drive device for endoscope leak detection and disinfection is proposed, including: a mounting seat, a linear driving mechanism, a negative suction button pressing column 12 and a water vapor button pressing column 13. Two linear driving mechanisms are provided, and the two linear driving mechanisms are fixedly mounted on the mounting seat, one linear driving mechanism is used to drive the negative suction button pressing column 12, and the other linear driving mechanism is used to drive the water vapor button pressing column 13, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 can perform pressing actions synchronously and independently and asynchronously (hereinafter described as step-by-step actions). It has strong applicability and can realize air and water supply and negative pressure suction work at the same time, saving time, being more efficient and convenient. In addition, the setting of the two linear driving mechanisms only requires forward movement to push the pressing column to move, reducing the need for backward movement, thereby saving installation space in the length direction and saving clinical space.

[0069] like Figure 7 As shown, the linear drive mechanism is a linear telescopic power structure 18. In this embodiment, the linear telescopic power structure 18 is an electric push rod. It can be understood that in other embodiments, the linear telescopic power structure 18 can also be an electric cylinder, a pneumatic cylinder or other structures. No excessive restrictions are made here.

[0070] In this embodiment, the mounting base includes a base 19 and a pressure plate 20. The base 19 is fixedly mounted on the shell of the automatic pretreatment equipment by bolts. The base 19 is provided with a groove matching the shape of the linear telescopic power structure 18, and bosses are fixedly provided at the front and rear ends of the base 19 for positioning and installing the linear telescopic power structure 18. The two linear telescopic power structures 18 are laterally fixedly mounted in the groove of the base 19, and the two linear telescopic power structures 18 are arranged opposite to each other up and down. The pressure plate 20 is fixedly mounted on the base 19 by bolts for covering the linear telescopic power structure 18 and assisting in positioning.

[0071] A pressing block 21 is fixedly installed on the telescopic end of each linear telescopic power structure 18. The position distance between the two linear telescopic power structures 18 is the same as the position distance between the negative pressure suction button and the air and water supply buttons on the handle of the soft endoscope, and they correspond one to one. Specifically, the linear telescopic power structure 18 located on the upper side abuts against the negative suction button pressing column 12 through the pressing block 21 at its end, and the linear telescopic power structure 18 located on the lower side abuts against the water and gas button pressing column 13 through the pressing block 21 at its end.

[0072] In order to improve the control accuracy of the pressing stroke of the negative suction button pressing column 12 and the water gas button pressing column 13, the linear telescopic power structure 18 itself is integrated with a position sensor, such as a Hall sensor or a high-precision encoder, so that the structure is simpler and more compact, and the position accuracy control accuracy is higher. An external position sensor can also be set to achieve accurate monitoring of the 0-point position to ensure precise control of the pressing stroke of the negative pressure suction button and the air and water supply buttons each time.

[0073] The negative suction button pressing column 12 and the water vapor button pressing column 13 are both placed horizontally, and the negative suction button pressing column 12 and the water vapor button pressing column 13 are arranged relatively to each other up and down, and the negative suction button pressing column 12 and the water vapor button pressing column 13 are both slidably arranged in the guide sleeve 11, so that the negative suction button pressing column 12 and the water vapor button pressing column 13 are guided by the guide sleeve 11 to avoid deviation of the negative suction button pressing column 12 and the water vapor button pressing column 13 when they are in action.

It has strong applicability and can realize air and water supply and negative pressure suction work at the same time, saving time, being more efficient and convenient. In addition, the setting of the two linear driving mechanisms only requires forward movement to push the pressing column to move, reducing the need for backward movement, thereby saving installation space in the length direction and saving clinical space.

The flexible block 14 contacts the negative suction button on the endoscope handle, which not only protects the surface of the endoscope button from damage, but also achieves sealed contact with the button surface. When the air supply action is performed, there is no gas leakage.

[0082] It is understandable that in other embodiments, the guide sleeve 11 may not be provided, and other lubrication structures may be used, or the negative suction button pressing column 12 and the water vapor button pressing column 13 may be directly installed on the pretreatment equipment housing.
