DETAILED DESCRIPTION

[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] like Figure 1 As shown, a cup dispensing mechanism of a flexible endoscope bedside pre-cleaner includes a cup storage assembly and a cup dispensing assembly, the cup storage assembly includes a fixed plate 1 and at least three limiting rods 2, the fixed plate 1 is provided with a cup dropping notch 1-1, the limiting rods 2 are vertically fixed on the fixed plate 1, and the limiting rods 2 are distributed around the cup dropping notch 1-1, the disposable cleaning cups 100 are stacked up and down in the space surrounded by the limiting rods 2, and the cup mouth of the disposable cleaning cup 100 has a cup rim 101 radially protruding outward from the cup mouth. Figure 1In the embodiment shown, the cup storage assembly includes four limiting rods 2, the cup drop notch 1-1 is circular, and the four limiting rods 2 are evenly distributed around the cup drop notch 1-1. The disposable cleaning cups 100 stacked in the space surrounded by the limiting rods 2 fall one by one from the cup drop notch 1-1 through the cup separation assembly to the cup retrieval assembly waiting in advance below the cup separation assembly. The inner diameter of the cup drop notch 1-1 is larger than the maximum outer diameter of the disposable cleaning cup 100, so that the disposable cleaning cup 100 can fall smoothly.

[0020] The cup-distributing assembly comprises a cylinder 3, a U-shaped connecting rod 4, a cup-distributing plate 5 and a slide rail 6. The cylinder body of the cylinder 3 is fixed on the fixed plate 1. The end of the protruding rod of the cylinder 3 is fixed to the tail of the U-shaped connecting rod 4. A cup-distributing plate 5 is fixed to each of the two heads of the U-shaped connecting rod 4. The two cup-distributing plates 5 are symmetrically arranged relative to the cup storage assembly and are respectively located on both sides of the cup storage assembly. A slide rail 6 is provided under each cup-distributing plate 5. The cup-distributing plate 5 is slidably connected to the slide rail 6. The cup-distributing plate 5 abuts against the bottom of the cup edge 101 of the lowest disposable cleaning cup 100. The open end of the U-shaped connecting rod 4 faces the cup storage assembly. The cup-distributing plate 5 abuts against the bottom of the cup edge 101 of the lowest disposable cleaning cup 100, that is, the two cup-distributing plates 5 on both sides of the U-shaped connecting rod 4 respectively hold the two sides of the cup edge 101 of the disposable cleaning cup 100 to prevent the disposable cleaning cup 100 from falling. The setting of the slide rail 6 can ensure the moving track of the cup separation plate 5, thereby ensuring the distance between the cup separation plate 5 and the cup edge 101 of the disposable cleaning cup 100, and ensuring smooth cup separation. At the same time, the slide rail 6 can also make the movement of the cup separation plate 5 smoother.

[0021] like Figure 3-5 As shown, the cup-distributing plate 5 comprises a starting section 5-1, an intermediate section 5-2 and a receiving section 5-3, the starting section 5-1 and the receiving section 5-3 are connected through the intermediate section 5-2, the receiving section 5-3 is fixedly connected to the head of the U-shaped connecting rod 4, the intermediate section 5-2 is an inclined surface so that the receiving section 5-3 is higher than the starting section 5-1, and the intermediate section 5-2 has a cup-distributing notch 5-4 on the side facing the cup storage assembly, which is recessed in the starting section 5-1 and the receiving section 5-3, and the depth D1 of the cup-distributing notch 5-4 recessed in the starting section 5-1 and the depth D2 of the cup-distributing notch 5-4 recessed in the receiving section 5-3 are both greater than the radial width d of the cup rim 101 of the disposable cleaning cup 100, the projection width W of the cup-distributing notch 5-4 is less than the maximum width L1 of the contact between the starting section 5-1 and the cup rim 101, and the projection width W of the cup-distributing notch 5-4 is less than the maximum width L2 of the contact between the receiving section 5-3 and the cup rim 101. The projection width mentioned here refers to the width projected onto the moving plane of the cup-separating plate 5. In fact, the moving plane of the cup-separating plate 5 is parallel to the plane where the cup edge is located. Figure 6-7As shown, when the contact area between the starting section 5-1 and the cup edge 101 is the largest, the overlapping portion is in an arc shape, and the maximum width L1 between the starting section 5-1 and the cup edge 101 is actually the length of the chord of the arc. When the contact area between the receiving section 5-3 and the cup edge 101 is the largest, the overlapping portion is also in an arc shape, and the maximum width L2 between the receiving section 5-3 and the cup edge 101 is actually the length of the chord of the arc.

[0022] The height difference between the receiving section 5-3 and the starting section 5-1 is the same or substantially the same as the height difference between the cup edges 101 of two adjacent disposable cleaning cups 100 stacked in the storage cup assembly, or the height difference between the receiving section 5-3 and the starting section 5-1 is smaller than the height difference between the cup edges 101 of two adjacent disposable cleaning cups 100 stacked in the storage cup assembly. In this way, after the starting section 5-1 supports the bottommost disposable cleaning cup 100, the receiving section 5-3 abuts against the penultimate disposable cleaning cup 100.

[0023] like Figure 2 As shown, the center of the tail of the U-shaped connecting rod 4 has an upwardly folded mounting piece 4-1, which is fixedly connected to the end of the extending rod of the cylinder 3. The two ends of the U-shaped connecting rod 4 are bent upward to form step portions 4-2, and the step portions 4-2 are fixed to the receiving section 5-3 of the cup separating plate 5.

[0024] The action process of the cup-dispensing mechanism of the bedside pre-cleaner for flexible endoscopes of the utility model is as follows:

[0025] In the initial state, the cup edge 101 of the lowest disposable cleaning cup 100 is supported by the starting section 5-1 of the cup separating plate 5, and the cylinder 3 extends to make the U-shaped connecting rod 4 pull the cup separating plate 5 to slide along the slide rail 6, and the cup edge 101 of the lowest disposable cleaning cup 100 will pass through the inclined middle section 5-2. Since the side of the middle section 5-2 facing the cup storage assembly is concave in the starting section 5-1 and the receiving section 5-3, and the middle section 5-2 is concave in the depth D1 of the starting section 5-1 and the inner depth D2 of the middle section 5-2, the cup edge 101 of the lowest disposable cleaning cup 100 will pass through the inclined middle section 5-2. The depth D2 of the recessed receiving section 5-3 is greater than the radial width d of the cup edge 101 of the disposable cleaning cup 100. When passing by, the cup edge 101 of the lowest disposable cleaning cup 100 does not contact the middle section 5-2. Since the receiving section 5-3 is higher than the starting section 5-1, the cup edge 101 of the lowest disposable cleaning cup 100 continues to move from the middle section 5-2 recessed in the cup separation notch 5-4 of the starting section 5-1 and the receiving section 5-3 to the bottom of the receiving section 5-3. Since the projection width W of the cup separation notch 5-4 is smaller than the maximum width L1 of the contact between the starting section 5-1 and the cup edge 101, before the lowest disposable cleaning cup 100 falls, the receiving section 5-3 can abut against the second to last disposable cleaning cup 100 to ensure that only one disposable cleaning cup 100 falls at a time. When the bottom disposable cleaning cup 100 falls, the two receiving sections 5-3 of the two cup-distributing plates 5 have supported both sides of the penultimate disposable cleaning cup 100. After the bottom disposable cleaning cup 100 falls, the penultimate disposable cleaning cup 100 becomes the bottom disposable cleaning cup 100. At this time, the cylinder 3 is retracted, and the cup edge 101 of the new bottom disposable cleaning cup 100 passes through the cup-distributing notch 5-4. Since the projection width W of the cup-distributing notch 5-4 is smaller than the maximum width L2 of the receiving section 5-3 in contact with the cup edge 101, it is ensured that the cup edge 101 passes through the middle section 5-2 and is always in contact with the receiving section 5-3 before contacting the starting section 5-1, that is, the cup edge 101 of the new bottom disposable cleaning cup 100 is finally supported by the starting section 5-1 and returns to the initial position. At this time, a cup-distributing process ends.

[0026] When the flexible endoscope bedside pre-cleaner is used for bedside pretreatment of the endoscope, the enzyme solution is first heated, and then the cup taking assembly is moved to below the cup drop notch 1-1, and the cylinder action of the cup dividing assembly realizes the falling of a disposable cleaning cup 100, and the disposable cleaning cup 100 just falls into the cup taking assembly, and the cup taking assembly clamps the disposable cleaning cup 100 and moves it to below the liquid outlet of the enzyme solution, and after taking the specified volume of enzyme solution, the cup taking assembly continues to move to send out the disposable cleaning cup 100 containing the enzyme solution, and the endoscope aspirates the enzyme solution for internal cleaning.

[0027] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
