Abstract
The utility model discloses a double-way gear pump. The double-way gear pump comprises a frame structure, a transmission mechanism and a motor for driving the transmission mechanism, wherein the frame structure comprises a cavity, an upper cover on the cavity and a lower cover below the cavity; the motor is positioned in the cavity, a motor shaft is provided with a worm rod, the worm rod drives a worm wheel for transmission, and the worm wheel drives gear groups in a gear cavity to rotate; each gear group comprises a driving gear and a driven gear, and the driving gears and the driven gears can form positive pressure and negative pressure to pump liquids through rapid rotation. The double-way gear pump provided by the utility model has the advantages that the two gear groups are driven to rotate through a transmission gear, the mechanism is small, the cost is low, the installation is reliable, two different laundry detergents are pumped, the functions are comprehensive, and the double-way gear pump is suitable for different washing machines.
Description
Technical field
The utility model relates to a kind of laundry washer liquid pump, is specifically related to a kind of two-way gear pump.
Background technique
At present, on washing machine, great majority adopt how group pumps are used for extracting the washing agent such as different liquid detergents, emollients, but the problems such as existing many group pump structures are larger, installation trouble, expensive, utilization ratio is not high.
Model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of two-way gear pump, and mechanism is small and exquisite, with low cost, installs more reliably, and can extract two kinds of different liquid detergents.
Technological scheme: for achieving the above object, a kind of two-way gear pump of the present utility model, the motor that comprises frame structure, driving mechanism and drive transmission device, described frame mechanism comprises die cavity, be positioned at the upper cover above die cavity and be positioned at the lower cover below die cavity, described motor is positioned at die cavity the inside, motor shaft is provided with worm screw, worm screw drives worm drive, the gear train in worm gear driven gear chamber rotates, described gear train comprises driving gear and driven gear, and driving gear and driven gear fast rotational form malleation and negative pressure comes pump to get liquid.
As preferably, two ends, described motor left and right are all provided with motor shaft, described worm screw comprises left worm screw and right worm screw, left worm screw and right worm screw lay respectively on motor the right and left axle, described worm gear comprises left worm gear and right worm gear, left worm screw is connected with right worm gear with left worm gear respectively with right worm screw, thereby drives the gear train of left and right two gear cavities to rotate.
As preferably, described left gear chamber and right gear chamber are formed by sealing gasket and upper cover.
Beneficial effect: a kind of two-way gear pump of the present utility model, mechanism is small and exquisite, with low cost, installs more reliably, and can extract two kinds of different liquid detergents, and complete function, is applicable to various washing machines.
