Abstract

The utility model relates to the technical field of flow pump bodies and particularly discloses to a fluid body driving mechanism of a bathroom hose pump, which solves the technical problems existed in the prior art of unreasonable design and easy damage. The utility model comprises a central shaft, an upper disc body and a lower disc body are respectively fixed at two ends of the central shaft, a plurality of rollers for squeezing a hose are arranged between the upper and the lower disc bodies, the rollers take the shapes of waist drums, and the axle center lines of the rollers and that of the central shaft are in parallel arrangement. Compared with the prior art, the fluid body driving mechanism of a bathroom hose pump has the advantages that firstly, reasonable structural design, good working stability, and high mechanical strength are achieved; and secondly, the working stability can be effectively improved, the fluid body can be conveniently and smoothly delivered, the damage to the hose is difficult to occur, and the service life of the bathroom hose pump is greatly prolonged.

Description

The fluid drives mechanism of sanitary hose pump

Technical field

The utility model relates to flow pumps body technique field, relates to sanitary hose pump, especially relates to a kind of fluid drives mechanism of sanitary hose pump.

Background technique

Peristaltic pump is the hocketed extruding and discharge pumping fluid of the elasticity delivery hose that utilizes pump.Along with the transfer roller of peristaltic pump moves, transfer roller sidepiece squeezing tube forms negative pressure in pipe, and one section flexible pipe between two transfer rollers forms " pillow " shape fluid, and along with transfer roller is rotated further, the interior liquid of flexible pipe is mobile thereupon.The fluid drives mechanism of sanitary hose pump is an important spare part, and whether reasonable performance to whole sanitary hose pump has material impact to its structural design.

Chinese patent literature discloses a kind of finger-type peristaltic pump [application number: 200580045471.3], comprise the pump housing and housing, the described pump housing comprises the processor that two or more refer to the type valve and are configured to operate according to scheduled time spatial model described valve, described housing has the passage that is configured to holding conduit, described housing has the primary importance and the second place, in described primary importance, the conduit in the described passage and the finger type spare of described valve are adjacent to the location, in the described second place, the finger type spare with described valve is not adjacent for the conduit in the described passage.The somebody has invented a kind of peristaltic pump [application number: 200480021722.X] that transmits the flexible pipe inner fluid, and this flexible pipe has first end, intermediate portion, second end, and described peristaltic pump comprises: the roll assembly that is used to rotate; First, the close described roll assembly in its position, and around the first direction pivot; With second, the close described roll assembly in its position, and around the second direction pivot; Thereby, described first and described second can be on pivot rotating opening, and the described intermediate portion of described flexible pipe is positioned at around the described roll assembly.

Though such scheme has improved service behaviour to a certain extent, still exist and be difficult to manufacturing, working stability is relatively poor, easily flexible pipe is caused technical problems such as damage.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of good operating stability is provided, and is difficult for the fluid drives mechanism that flexible pipe is caused the sanitary hose pump of damage.

For achieving the above object, the utility model has adopted following technical proposal: the fluid drives mechanism of this sanitary hose pump, be arranged in the pump housing, it is characterized in that, this fluid drives mechanism comprises central shaft, be fixed with disk body and following disk body at the two ends of central shaft respectively, be provided with some rollers that are used for squeezing tube between last disk body and following disk body, described roller is the axis parallel setting of the shaft axis and the central shaft of waist drum type and roller.

In the fluid drives mechanism of above-mentioned sanitary hose pump, the quantity of described roller is 2-6 and the evenly distribution in a circumferential direction of each roller.

In the fluid drives mechanism of above-mentioned sanitary hose pump, the lower end of described central shaft has the attachment hole that can link to each other with live axle.

In the fluid drives mechanism of above-mentioned sanitary hose pump, the upper end of described central shaft passes disk body, and is with bearing in this end periphery.

In the fluid drives mechanism of above-mentioned sanitary hose pump, described going up is fixed with some bodies of rod that are provided with central axes between disk body and the following disk body, and described roller is movably set on the body of rod.

Compared with prior art, the advantage of the fluid drives mechanism of this sanitary hose pump is: 1, reasonable in design, good operating stability, mechanical strength height.2, effectively improve working stability, be convenient to fluid and be transferred swimmingly, and be difficult for flexible pipe is caused damage, improved the working life of sanitary hose pump greatly.
