Abstract
The utility model discloses a miniature peristaltic pump which comprises a frame structure, a motor and a transmission structure. The frame structure comprises a lower cover and an upper cover, wires of the motor are led outside through a wire leading ring, the transmission structure comprises a worm rod installed on a motor shaft and a worm wheel meshed with the worm rod, three rotors evenly distributed are installed below the worm wheel, a tripod is installed below the rotors to for supporting and balancing, the worm wheel, the tripod and the rotors rotate around a smooth shaft, a peristaltic pipe is arranged outside the rotors, the worm wheel rotates to drive the rotors to move in a rotating and revolving mode, and the rotors rotate to evenly press the peristaltic pipe in a cavity in a rolling mode to extract or discharge liquid. According to the miniature peristaltic pump for automatic liquid injection, external equipment provides a direct current power supply, and a direct current motor can be applied to an ordinary domestic appliance. The miniature peristaltic pump for the automatic liquid injection is smaller and more exquisite in product structure, longer in service life and lower in cost. The worm wheel and the worm rod are utilized for transmitting motive power, and the peristaltic pipe is pressed in the rolling mode through the transmission of the worm wheel, and the whole efficiency can be promoted.
Description
Technical field
The utility model relates to a kind of for the pump on the washing machine, is specifically related to a kind of miniature peristaltic pump for extracting the washing agent such as liquid detergent, emollients.
Background technique
At present, great majority are equipped with for the pump that extracts the washing agent such as liquid detergent, emollients on the washing machine, but existing pump all is to be driven by AC motor, and its structure is larger, expensive, working life is shorter.
The model utility content
The deficiency that exists in order to overcome the prior art condition, the utility model provide a kind of miniature peristaltic pump that can be driven by direct current generator.
Miniature peristaltic pump described in the utility model, comprise frame structure, motor and drive mechanism, described frame structure comprises lower cover and loam cake, motor wire is introduced outside by the threading circle, described drive mechanism comprise the worm screw that is installed on the motor shaft and with the worm gear of worm meshing, described worm gear below is equipped with three rotors, rotor below is equipped with that tripod supports and balance, described turbine, tripod and rotor rotate around optical axis, the rotor outside is provided with peristaltic tube, worm gear rotates rotor driven rotation and revolution motion, and rotor rotates and balancedly rolls the peristaltic tube extraction that is positioned at die cavity or discharge liquid.
For the active force that acts on the worm gear is cancelled out each other, guarantee that worm gear moves without acceptance of persons, three of rotor driven balanced layouts of pillar on the worm gear, in order to extract or to get rid of liquid, described peristaltic tube two ends are respectively liquid entering hole and liquid outlet.
Beneficial effect: miniature peristaltic pump of the present utility model compared with prior art has following advantage:
1, adopts pump and circuit unpack format, provide DC electrical source by external equipment, direct current generator can be applied in the normal domestic use electrical equipment, make the structure of product smaller and more exquisite, longer service life, cost be cheaper;
2, roll peristaltic tube by employing worm and gear transferring power, and by worm drive, whole structure is improved.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, miniature peristaltic pump of the present utility model, comprise frame structure, motor 6 and drive mechanism, frame structure comprises loam cake 1 and lower cover 2, motor wire is introduced outside by threading circle 5, drive mechanism comprise the worm screw 7 that is installed on the motor shaft and with the worm gear 8 of its engagement, worm gear 8 belows are equipped with three rotors 9, rotor 9 belows are equipped with tripod 11 and support and balance, three's (worm gear, rotor and tripod) around optical axis 10 rotations, rotor 9 outsides are provided with peristaltic tube 4, and worm gear 8 rotates rotor driven 9 rotations and revolution motion, and rotor 9 rotates and balancedly rolls peristaltic tube 4 extractions that are positioned at die cavity or discharge liquid.
In the present embodiment, three of rotor driven 9 balanced layouts of pillar on the worm gear 8, the active force of being convenient to act on the worm gear 8 is cancelled out each other, and guarantees that worm gear 8 moves without acceptance of persons; Peristaltic tube 4 two ends are respectively imports and exports 3 liquid entering hole 31 and liquid outlet 32, is convenient to extract or get rid of liquid.
Miniature peristaltic pump of the present utility model in the course of the work, the outside provides DC electrical source (for example 12V) to motor 6 power supplies, worm screw 7 on the motor 6 drive motor axles, worm screw 7 drives worm gear 8 rotor drivens 9 again and tripod 11 rotates together, and rotor 9 rotates and repeatedly rolls peristaltic tube 4 extractions that are positioned at die cavity or discharge liquid.
