In this embodiment, a fan 151 is connected to an end of the motor 11 away from the turret 17, and a rotation speed sensor 152 is disposed at the end, and the rotation speed sensor 152 senses the rotation of the blades of the fan 151, so that a chip connected to the rotation speed sensor 152 can calculate the rotation speed of the turret 17, and thus the flow rate of the delivery pipe 13.

The working principle of the invention is as follows: the motor 11 drives the driving gear 161 to rotate, so as to drive the plurality of driven gears 162 to rotate along the gear portion 143, and drive the rotating rack 17 to rotate through the rotating disk 163, and then the rotating rack 17 drives the plurality of rollers 18 to rotate, and the rollers 18 alternately extrude and release the elastic conveying pipe 13 to pump the fluid in the conveying pipe 13.

When the peristaltic pump with the false touch prevention structure is installed, the conveying pipe 13 can firstly surround the periphery of the roller 18 arranged on the rotating frame 17, and then the two ends of the conveying pipe 13 are fixed by the positioning rings 19, so that the conveying pipe 13 and the rotating frame 17 form primary connection;

then, the joint member 21 is clamped into the housing 12, the housing 12 is connected with the transmission case 14, the plurality of arc-shaped strips 212 are kept close to the housing 12 under the action force of the elastic ring 213, so that a gap is formed between the arc-shaped strips 212 and the conveying pipe 13, and the matching assembly can be conveniently carried out, when the joint member 21 and the housing 12 are gradually connected in place, the extrusion block 141 can extrude the arc-shaped strips 212, so that the arc-shaped strips 212 slide along the sliding columns 217 towards the direction close to the conveying pipe 13, and the arc-shaped strips 212 extrude the conveying pipe 13, so that the arc-shaped strips 212 and the rollers 18 can extrude the conveying pipe 13 better to pump fluid.

The peristaltic pump with the false touch prevention structure of the preferred embodiment is provided with the connecting piece through the movement on the inner wall of the shell, and the connecting piece has a certain movement space, so that the conveying pipe can be arranged between the wheel surface of the roller and the connecting piece more easily, and the assembly and disassembly are more convenient.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
