After said structure, the present invention drives roll wheel assembly rotation by micro motor, extrudes bullet using roll wheel assembly
Property flexible pipe carries out fluid conveying；And the design replaces sliding friction to carry out extruding conveying by rolling friction, serves and prolongs
The effect of long soft-pipe service life and reduces cost；And the design also has simple structure, easily fabricated and practicality and high efficiency
Advantage.
Description of the drawings
Under the present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural blast schematic diagram of the present invention.
Structural representations of the Fig. 2 for roll wheel assembly.
Fig. 3 is the enlarged drawing of A in Fig. 1.
Specific embodiment
A kind of novel peristaltic pump head as shown in Figure 1, including micro motor 1, pump head pedestal 2, roll wheel assembly 3 and pump head
Upper lid 4, the upper surface of described pump head pedestal 2 open up fluted, and described roll wheel assembly 3 is located in the groove of pump head pedestal 2,
On described pump head, lid 4 is connected to the top of pump head pedestal 2, and described roll wheel assembly 3 is located at lid 4 on pump head pedestal 2 and pump head
Between, the center of the groove offers through hole 14, and the shaft end that goes out of described micro motor 1 passes through through hole 14 and roll wheel assembly
3 are meshed, and described micro motor 1 goes out first gear 13 on shaft end, and described micro motor 1 passes through first gear
13 are connected with roll wheel assembly 3, and on described pump head, the side of lid 4 offers two " U " font turnover mouths of pipe 11.The groove
Draw-in groove 15 is provided with the wall of side, the outside of lid 4 is provided with dop 16 on the pump head, lid 4 passes through dop 16 on described pump head
With being connected in the groove of pump head pedestal 2 for draw-in groove 15.Elastic hose is installed in pump head before work, make elastic hose
Body contact with roll wheel assembly 3, the two ends of elastic hose two " U " fonts turnover mouths of pipe respectively from pump head on lid 4
11 stretch out, and when needing to carry out fluid conveying, start miniature micro motor 1 and are passed to first gear 13 with roll wheel assembly 3
Rotated, being extruded using roll wheel assembly 3 carries out fluid conveying using roll wheel assembly extruding elastic hose.The design has structure
The advantage of simply, easily fabricated and practicality and high efficiency.
Roll wheel assembly 3 as shown in Figure 2 includes roller lower carriage 5, the roller 8 with gear and roller upper bracket 6, described
Roller lower carriage 5 is provided with three root posts 9, and three with three root posts, 9 corresponding cooperation are offered on described roller upper bracket 6
Individual connecting hole, is respectively set with a roller 8 with gear on three described root posts 9, described micro motor 1 passes through the first tooth
Wheel 13 is meshed with the gear end of three rollers 8 respectively.After micro motor 1 is started, micro motor 1 passes through 13 band of first gear
Three rollers 8 with gear to be rotated, roller lower carriage 5 and roller upper bracket 6 can also follow one in the presence of inertia
With rotating, elastic hose is extruded by roller 8, carries out fluid conveying using elastic hose, and roller 8 with elasticity
Flexible pipe can occur rotation while contact, so as to replace sliding friction to pressurize elastic hose using rolling friction, significantly
