Embodiment 1

[0077] like Figure 1-7 As shown, the squeeze type peristaltic pump includes: a main body 1, a transmission component (camshaft 9), a first pressing unit (including: a first liquid inlet cut-off block 3, a first working pressure block 4, a first liquid discharge cut-off block Block 5), the second pressing unit (including: the second liquid inlet cut-off block 6, the second working pressure block 7, the second liquid discharge cut-off block 8), the hose (including the first branch pipe 13, the second branch pipe 14, the summary tube 15), the first limiting plate 201, the second limiting plate 202. The first limiting plate 201 and the second limiting plate 202 are respectively disposed on the upper and lower sides of the main body 1 and are fixedly connected with the main body 1 by screws.

[0078] The hose includes a first branch pipe 13 , a second branch pipe 14 , a collective pipe 15 and a tee joint 16 for connecting the above three components.

[0079] The first branch pip...

Embodiment 2

[0115] Different from the first embodiment, the transmission component includes a first transmission unit and a second transmission unit, the first pressing unit reciprocates under the driving of the first transmission unit, and the second pressing unit is in the Reciprocating motion is performed under the driving of the second transmission unit. That is, the first pressing unit and the second pressing unit are individually controlled.

[0116] It should be noted that the first transmission unit and the second transmission unit are not related, and the structures of the two may be the same or different. Similarly, the structures of the first pressing unit and the second pressing unit may be the same or different.

[0117] In this embodiment, one limit plate may be used to limit the two branches of the hose at the same time. Two can also be used to limit the two branches of the hose respectively.

[0118] With this design, the structure is more complicated, the occupied volu...

Embodiment 3

[0121] Different from the first embodiment, the transmission component can be a link mechanism, and one end of the pressing unit performs linear reciprocating motion (such as Figure 8 shown), squeeze the hose periodically.

[0122] like Figure 8 As shown, the first link 17 can be rotated with one end as the center, and then the first link 17 drives the second link 18 to rotate, and the second link 18 pushes the slider 19 to move along a straight line, wherein the slider 19 can be used as an extrusion part Squeeze the hose.

[0123] Among them, the liquid inlet cut-off cam, the extrusion cam and the work cut-off cam can all adopt the above structures.

Abstract

The extrusion type peristaltic pump comprises a body, a transmission part, a first pressing unit, a second pressing unit, a limiting plate and a hose, the limiting plate is fixedly connected with the body, and the hose comprises a first branch pipe and a second branch pipe; the first branch pipe is arranged between the limiting plate and the first pressing unit, and the first pressing unit is driven by the transmission part to do reciprocating motion and used for pressing the first branch pipe; the second branch pipe is arranged between the limiting plate and the second pressing unit; the second pressing unit is driven by the transmission part to reciprocate and used for pressing the second branch pipe, the first branch pipe and the second branch pipe are alternately pressed, and the hose continuously discharges liquid. According to the scheme, the first branch pipe and the second branch pipe alternately extrude and convey the fluid to the gathering pipe, finally continuous conveying of the fluid in the gathering pipe is achieved, fluid cutoff is avoided, the flow stability in the fluid conveying process is improved, and pulsation is reduced.

Description

technical field [0001] The present application relates to the technical field of peristaltic pumps, and in particular, to a squeeze-type peristaltic pump. Background technique [0002] Peristaltic pumps, also known as hose pumps, are used to generate fluid flow within a flexible tubular conduit for fluid delivery. The existing peristaltic pump is usually a rotary peristaltic pump, which has the problems of large wear on the catheter and easy pipeline deviation after long-term use. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present application provide a squeeze-type peristaltic pump, which is used to improve the life of the hose and provide stable continuous fluid. [0004] In order to solve the above-mentioned technical problems, the embodiments of this specification are implemented as follows: [0005] A squeezing type peristaltic pump provided by the embodiments of this specification includes: a main body, a transmission component, a firs...
