Further: described roll wheel assembly comprises roller lower support frame, the roller being with gear and roller upper bracket, described roller lower support frame is provided with three root posts, described roller upper bracket offers three attachment holes with the corresponding cooperation of three root posts, three described root posts are respectively set with the roller of a band gear, described micro motor is meshed with the gear end of three rollers respectively by the first gear.
Further again: the outside of the roller of three described band gears is provided with annular baffle, and described annular baffle is positioned at the top of roller gear end.
Further again: the sidewall of described groove is provided with draw-in groove, the arranged outside of described pump head upper cover has dop, and described pump head upper cover is connected in the groove of pump head pedestal by dop and draw-in groove.
Further again: the sidewall in described " U " font turnover mouth of pipe offers clip groove.
After adopting said structure, the present invention drives roll wheel assembly to rotate by micro motor, utilizes roll wheel assembly to extrude elastic hose and carries out fluid conveying; And the design replaces sliding friction to carry out extruding conveying by rolling friction, serves the effect extending flexible pipe working life and reduce costs; And the design also has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
Accompanying drawing explanation
Under below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural blast schematic diagram of the present invention.
Fig. 2 is the structural representation of roll wheel assembly.
Fig. 3 is the enlarged view of A in Fig. 1.
Embodiment
A kind of Novel peristaltic pump head as shown in Figure 1, comprise micro motor 1, pump head pedestal 2, roll wheel assembly 3 and pump head upper cover 4, the upper surface of described pump head pedestal 2 offers groove, described roll wheel assembly 3 is positioned at the groove of pump head pedestal 2, described pump head upper cover 4 is connected to the top of pump head pedestal 2, described roll wheel assembly 3 is between pump head pedestal 2 and pump head upper cover 4, the center of described groove offers through hole 14, the axle head that goes out of described micro motor 1 is meshed with roll wheel assembly 3 through through hole 14, going out on axle head of described micro motor 1 is provided with the first gear 13, described micro motor 1 is connected with roll wheel assembly 3 by the first gear 13, the side of described pump head upper cover 4 offers two " U " font turnover mouths of pipe 11.The sidewall of described groove is provided with draw-in groove 15, the arranged outside of described pump head upper cover 4 has dop 16, and described pump head upper cover 4 is connected in the groove of pump head pedestal 2 by dop 16 and draw-in groove 15.Before work, elastic hose is fit in pump head, the body of elastic hose is contacted with roll wheel assembly 3, the two ends of elastic hose are stretched out from " U " font turnover mouth of pipe 11 of two pump head upper cover 4 respectively, when needs carry out fluid conveying, starting miniature micro motor 1 makes it be rotated with roll wheel assembly 3 by the first gear 13, utilizes roll wheel assembly 3 to extrude and utilizes roll wheel assembly extruding elastic hose to carry out fluid conveying.The design has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
Roll wheel assembly 3 as shown in Figure 2 comprises roller lower support frame 5, the roller 8 being with gear and roller upper bracket 6, described roller lower support frame 5 is provided with three root posts 9, described roller upper bracket 6 offers three attachment holes with the corresponding cooperation of three root posts 9, three described root posts 9 are respectively set with the roller 8 of a band gear, described micro motor 1 is meshed with the gear end of three rollers 8 respectively by the first gear 13.When after startup micro motor 1, micro motor 1 is rotated by the roller 8 of the first gear 13 with three band gears, roller lower support frame 5 and roller upper bracket 6 also can be followed and together rotate under the effect of inertia, extruded by roller 8 pairs of elastic hoses, elastic hose is utilized to carry out fluid conveying, and can rotation be there is in roller 8 while contacting with elastic hose, thus utilize rolling friction to replace sliding friction to pressurize to elastic hose, greatly reduce the wearing and tearing of friction to elastic hose, serve the effect extending flexible pipe working life and reduce costs.
