Figure 1 The direction shown is consistent with the front, back, left, right, up and down directions of the device of the utility model when viewed from the front.

[0022] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of at least two elements or the interaction relationship between at least two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] See also Figure 1-5, the utility model provides an embodiment: a water feeder for endoscope, comprising a main water tank 10 and a peristaltic pump 18, a transfer tube 13 is fixedly connected on the front end surface of the main water tank 10 near the peristaltic pump 18, and a rod 12 is fixedly connected to the output end of the electric telescopic cylinder 11 installed on the main water tank 10, wherein the rod 12 extends into the inner cavity of the transfer tube 13, and a pressure plug 27 is fixedly connected to the lower end surface of the rod 12, and the pressure plug 27 is in close contact with the inner cavity side wall of the transfer tube 13, a three-way joint 16 is fixedly connected to the transfer tube 13, and the three-way joint 16 is connected to the inner cavity of the transfer tube 13, and the endoscope hose 17 bypasses the peristaltic assembly 25 in the peristaltic pump 18 and is fixedly connected to the three-way joint 16, and at the same time, the water outlet 14 at the front end of the main water tank 10 is also connected to the three-way joint 16 through the guide tube 15;

[0025] When water needs to be delivered during use of the endoscope, the switch valve in the water outlet 14 is opened, so that the water in the electric telescopic cylinder 11 enters the endoscope hose 17 through the guide tube 15 and the three-way joint 16. At the same time, the electric telescopic cylinder 11 is started, thereby pushing the rod 12 to move downward, thereby causing the plug 27 to move downward, squeezing the inner cavity space at the bottom of the rotating cylinder 13, and the plug 27 moves to the connection port between the three-way joint 16 and the inner cavity of the rotating cylinder 13 and stops, thereby blocking the connection port, so that water can continue to flow from the guide tube 15 into the endoscope hose 17, and during the period when the plug 27 moves downward to the connection port between the three-way joint 16 and the inner cavity of the rotating cylinder 13, the plug 27 compresses the inner cavity of the rotating cylinder 13. The generated air pressure accelerates the water entering the endoscope hose 17 through the three-way joint 16, so that the water can reach the water outlet of the endoscope as soon as possible, thereby effectively reducing the time for the water flow to reach the water outlet of the endoscope during the initial water delivery, thereby avoiding the doctor's waiting time and greatly improving work efficiency. Moreover, when the water delivery is stopped, the electric telescopic cylinder 11 is started to retract the rod 12 to reset the plug 27. During the process of the plug 27 being pulled up from the connection port between the three-way joint 16 and the transfer cylinder 13 to its original position, the negative pressure generated in the inner cavity of the limiting portion 23 will suck the water retained in the endoscope hose 17 into the inner cavity of the transfer cylinder 13, thereby effectively avoiding the phenomenon that the residual water in the endoscope hose 17 will drip through the water outlet of the endoscope after the water delivery is stopped.

[0026] In addition, in one embodiment, the difference from the above embodiment is that an opening is provided at the top of the peristaltic pump 18, and a control slide 22 is slidably connected in the opening, the bottom end of the control slide 22 extends into the inner cavity of the peristaltic pump 18, and extension plates 24 are respectively provided on the front and rear end surfaces of the control slide 22, and a return spring is connected between the lower end surface of each extension plate 24 and the upper end surface of the peristaltic pump 18, and an electric-controlled telescopic cylinder 20 is fixedly installed on the rear area of ​​the upper end surface of the peristaltic pump 18, and a trapezoidal block 21 is fixedly connected to the telescopic end of the electric-controlled telescopic cylinder 20, and the trapezoidal block 21 and the facing end surfaces of the control slide 22 are both provided with inclined surfaces, and the left and right ends of the control slide 22 are respectively fixedly provided with limiting portions 23, and the bottom of the limiting portion 23 is provided with a rubber pad;

[0027] When the water supply is stopped, the electric telescopic cylinder 20 is also started at the same time, and the electric telescopic cylinder 20 is pulled back, so that the bottom end of the trapezoidal block 21 is disengaged from the upper end of the control slide 22, so that the control slide 22 will pop up a distance, so that the curved end of the bottom end of the control slide 22 is disengaged from the endoscope hose 17 on the peristaltic component 25, thereby releasing the squeezed part of the endoscope hose 17 and the peristaltic component 25, restoring the original diameter of the endoscope hose 17, and further facilitating the suction of the residue in the endoscope hose 17 into the inner cavity of the rotating cylinder 13.

[0028] It is worth mentioning that in order to facilitate the cleaning of the water sucked back into the rotating cylinder 13, in this embodiment, the bottom of the inner cavity of the rotating cylinder 13 is through-hole and a bottom plug 26 is detachably installed. By disassembling the bottom plug 26, the water in the inner cavity of the rotating cylinder 13 can be discharged.

[0029] It should be noted that, in order to facilitate the movement and adjustment of the peristaltic pump 18 , a base 19 is slidably mounted on the bottom of the main water tank 10 , and the peristaltic pump 18 is fixedly mounted on the base 19 .

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
