The pressing piece to be pressed is a hose for conveying liquid, the driving piece drives the driving piece to move, the driving piece drives the pressing piece to move simultaneously, the pressing piece is prevented from being extruded or released after the pressing piece moves, and when the pressing piece to be pressed is extruded, the infusion channel in the pressing piece to be pressed is closed to prevent the liquid from flowing through. When the pressure stop piece moves again, the pressure piece to be pressed is separated from the extrusion action of the pressure stop piece, and the internal channel is restored to allow the liquid to pass through.
In this embodiment, preferably, the driving member may be a steering engine 1, the steering engine is of a TD-8125MG type, and an output shaft 1.1 of the steering engine 1 is fixedly connected to the transmission member. The steering engine 1 is started, and an output shaft 1.1 of the steering engine drives the transmission piece to move. The driving medium can be rotary disk 2, rotary disk 2 is the circular disk, steering wheel 1's output shaft 1.1 fixed connection rotary disk central part 2.1, optionally, adopts fixed pin 5 to pass back by rotary disk central part 2.1 and screw at the output shaft of steering wheel to fixed the output shaft of rotary disk and steering wheel, drive the rotary disk rotation when the output shaft rotates.
On the basis of the above embodiment, the pressure stopping member provided by the embodiment includes a pressure lever 3, one end of the pressure lever 3 is provided with an axial clamping groove 3.1, the axial clamping groove 3.1 includes groove walls 3.11 at two sides, the rotating disc 2 is provided with an arc-shaped pushing groove 2.2, and part of the rotating disc 2 extends into the axial clamping groove 3.1; the compression bar 3 is connected with the rotary disc 2 through a fixing pin 5, the fixing pin 5 is penetrated through by a groove wall 3.11 at one side of the axial clamping groove 3.1, and penetrates through an arc-shaped pushing groove 2.2 of the rotary disc 2 and then penetrates out from a groove wall 3.11 at the other side of the axial clamping groove 3.1. Because the arc push slot 2.2 is arranged on the rotating disk 2, when the rotating disk 2 rotates, the arc push slot 2.2 rotates along with the rotating disk 2 to change the position of the through slot 6.31, and because the position of the pressure lever 3 in the vertical direction is fixed, the pressure lever 3 is influenced by the position change of the arc push slot 2.2, and the pressure lever 3 moves linearly along with the position change, and moves back and forth along the direction of the through slot 6.31, so that the pressing or releasing of the pressing piece to be treated is realized.
Because the steering engine 1 is internally provided with the angle sensor, the rotating angle of the output shaft can be sensed, and the rotating angle of the output shaft of the steering engine is the rotating angle of the rotating disk because the output shaft is fixedly connected with the central part of the rotating disk. The arc-shaped push groove 2.2 is provided with two end parts, including a first end part 2.21 and a second end part 2.22, and the included angle between the two end parts and the connecting line of the central part 2.1 of the rotating disc is a right angle; the length of the first end part 2.21 from the central part 2.1 of the rotating disk is 1.5-2 times, preferably 2 times, the length of the second end part 2.22 from the central part of the rotating disk, and the arc-shaped push groove 2.2 is positioned on the rotating disk and close to one side of the through groove of the mounting bracket, and the arc-shaped push groove is in a shape of being convex and concave outwards, i.e. the side close to the central part 2.1 of the rotating disk is concave inwards, so that the rotating disk 2 can freely rotate along with the output shaft of the steering engine within the angle defined by the arc-shaped push groove 2.2.
Because the distance between the arc-shaped push groove 2.2 and the central part 2.1 of the rotating disk gradually increases from the second end part 2.22 to the first end part 2.21, the fixing pin 5 passes through the arc-shaped push groove 2.2 when fixing the pressure rod 3 and the rotating disk 2, and the relative position of the fixing pin 5 in the arc-shaped push groove 2.2 is changed while the arc-shaped push groove 2.2 changes along with the rotating disk. When the rotating disk 2 rotates to enable the fixing pin 5 to be located at the first end portion 2.21 of the arc-shaped pushing groove 2.2, the first end portion 2.21 is far away from the center portion 2.1 of the rotating disk, and the pressing rod 3 moves towards the inside of the through groove 6.31 along with the rotation of the rotating disk 2 to press the piece to be pressed, so that liquid in the piece to be pressed is difficult to pass through. When the rotating disc 2 rotates 90 degrees, the fixing pin 5 is located at the second end 2.22 of the arc-shaped pushing groove 2.2, the second end 2.22 is closer to the center 2.1 of the rotating disc, the rotating disc 2 drives the pressing rod 3 to move towards the outer side of the through groove, the piece to be pressed is separated from the extrusion effect of the pressing rod 3, and liquid can pass through the piece to be pressed after an internal channel of the piece to be pressed is opened.
In order to save electricity and avoid continuous power supply for a steering engine, the axis of the pressure lever and the center of the rotary disc are positioned on the same horizontal line in the embodiment of the invention, so that when the anti-drip valve is in a closed state, the first end part, the center of the rotary disc and the axis of the pressure lever are positioned on the same horizontal line, the fixed pin is taken as a fulcrum of the lever, the thrust of the pressure lever is along the axis of the pressure lever and points to the fulcrum, and the resistance generated by the fixed pin and the center of the rotary disc also points to the fulcrum.
