Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described below.
Peristaltic pump schemes generally adopted by soap dispensers on the market can only be driven by common batteries due to the structural limitation of specific products, and a relatively soft silicone tube is generally adopted as a flow channel of liquid, so that the products of the type can not drive viscous liquid (such as liquid detergent, shampoo, hair conditioner, shower gel and the like) with non-Newtonian fluid characteristics.
As the silicone tube is always extruded in the using process, most peristaltic pumps on the market adopt tubes with soft hardness so as to avoid the deformation condition caused by multiple extrusion. Through many times of test demonstration, the hardness of silicone tube is selected the scope and is between 50 degrees to 60 degrees, has extrusion non-deformable and the high characteristics of resilience, consequently, the hardness of the elasticity silicone tube of this application sets up to be more than or equal to 52 degrees, the hardness of less than or equal to 60 degrees.
As shown in fig. 1, the roller rolls from position a to position B, and the volume of fluid delivered is approximately equal to the volume of fluid stored in the pump tube in arc AB, regardless of the volume occupied by the roller rolling the pump tube, i.e.:
d-pump casing circumference pitch circle diameter m;
d-pump tube inside diameter, m;
delta q-volume of fluid stored in arc AB section pump tube, m3；
Theta-angle of rotation of the rotating roller, rad;
δ — pump tube wall thickness, m;
the output flow when the input end of the peristaltic pump rotates for one circle is equal to 2 pi/theta delta q, namely:
formula q-peristalsisDisplacement of pump, m3。
The flow rate of the peristaltic pump is:
Q＝rq-6 (3)
formula Q-flow of peristaltic pump, m3/min；
r-rotational speed of peristaltic pump, r/min.
According to the formula (3), on the premise that the volume occupied by the roller grinding pump tube is not considered, the flow rate of the peristaltic pump is irrelevant to parameters such as the number of the rollers and the wall thickness of the pump tube, and is only relevant to the inner diameter of the pump tube, the diameter of the circumference pitch circle of the pump shell and the rotating speed of the peristaltic pump.

In the present embodiment, the driving assembly comprises a motor 3, a reduction gear 4, a motor transmission gear 5 and a planet wheel fixing base 6;
the motor 3 is arranged at the bottom of the device body, and a transmission shaft of the motor 3 is connected with a motor transmission gear 5; the planet wheel fixing base 6 comprises an outer ring and an inner ring, and the outer ring is fixedly connected with the inner wall of the device body; balls are preset between the outer ring and the inner ring, so that the inner ring rotates relative to the outer ring, and a circle of gears are preset at the bottom of the inner ring; the motor transmission gear 5 is in transmission connection with a gear at the bottom of the inner ring through the reduction gear 4, so that the motor 3 is used for transmitting the inner ring of the planet wheel fixing base 6 to rotate.

The locating component is a planet wheel fixing triangular plate 11, and the planet wheel fixing triangular plate 11 is fixed at the end parts of the three planet wheel fixing columns 7 through bolts, so that the cylindrical planet wheel 1 is prevented from being dislocated.
The planet wheel with three independent operations is fixed together, forms stronger extrusion force, produces more powerful squeezing action to the higher silicone tube of hardness, can not take place the position between the planet wheel to improve the vibrations problem that the planet wheel produced at high-speed rotation in-process, make the peristaltic pump have higher stability when the operation, on the other hand has ensured the vacuum requirement of peristaltic pump, has reached the state of not relieving pressure, has satisfied the demand of driving non-Newton's liquid.

The peristaltic pump has strong self-absorption capacity, theoretically, the maximum absorption distance for conveying water under a large force can reach 9.8 meters, but the flow of the peristaltic pump under the actual condition can be attenuated due to the influence of resistance and the like generated in a pipeline by the surface tension of a medium, and the flow of the peristaltic pump can be attenuated by 15 percent when the absorption distance is increased by one meter. The suction distance, the pump head hose and the medium are all related, and in order to meet the requirement of driving non-Newtonian fluid to flow out, the test result shows that the hose with the thinner inner diameter and the thicker wall thickness is selected, and meanwhile, the driver with the higher rotating speed is selected.

The diameter of the silicone tube is 0.7-1.5mm in wall thickness.
The size of the hose is too small compared with the size of the roller of the pump head, the pump head cannot be firmly clamped with the pump pipe, and the pump pipe can be pulled out of the pump head; also, if the pump tubing is too small, the rollers in the pump head may not compress the pump tubing, resulting in insufficient or complete failure of the pumped flow. If the pump tubing is too large, the excess tubing can wrinkle between the rollers and the pump housing or the rollers and the bite bed, resulting in excessive wear and premature failure.
In order to avoid the above situation, a mode of arranging a stopper 8 in the silicone tube is adopted, so that the silicone tube is prevented from being pulled out of the pump head. The inner diameter of the limiter 8 is consistent with that of the silicone tube, so that the non-Newtonian fluid can smoothly pass through the limiter.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
