There are gaps between moving gear and the cavity lateral of the pump housing；
Hollow contact pin is connected on end cap；The end of contact pin is as inlet；The root of contact pin passes through in end cap
Fluid passage is communicated with the rear side at gear pair occlusion；
Liquid outlet is equipped in pump housing side；The liquid outlet is communicated with the front side at gear pair occlusion.
Further, sealing ring is equipped between end cap and the pump housing, the sealing ring, which is located at outside the type chamber of the pump housing, to make a circle.
Further, contact pin protection cap is arranged outside contact pin.
Further, driving gear and driven gear are all made of straight-tooth gear.
Further, driving motor uses direct current generator.
Further, the side on the pump housing is additionally provided with the second bolt hole.
Further, contact pin is structure as a whole with end cap.
Utility model has the advantages that
1) part use is greatly decreased in the pump, the deficiency of low efficiency caused by reducing because of the cooperation of more parts；It is big with flow, at
This low advantage.
2) current drain is low, saves electric power.
3) it is directly inserted in cleaning solution bottle and uses, it is easy to use, without additional adapter tube.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model.
Fig. 2 is the appearance schematic diagram of the utility model.
Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
The utility model provides a kind of electric jet pump, since volume requirement is smaller, cannot use common turbine
Pump configuration, but cleverly use the structure of active and passive engaged gears.
As shown in Figure 1, the pump includes: contact pin protection cap 1, end cap 2, sealing ring 3, driving gear 4, driven gear 5, the pump housing
6, driving motor 7, inlet 8, liquid outlet 9；
Described 6 one end of the pump housing is bolted on driving motor 7；Driving motor 7 uses miniature DC motor；End cap
2 are bolted the other end for deviating from driving motor 7 on the pump housing 6；The first bolt being arranged on end cap 2 and the pump housing 6 in Fig. 1
Hole 601 connect use with the pump housing 6 for end cap 2；
The other end that the pump housing 6 is connect with end cap 2 is equipped with type chamber；The type of the pump housing 6 is arranged in driving gear 4 and driven gear 5
In chamber, driving gear 4, driven gear 5 are mutually twisted to form gear pair；Driving gear 4 and driven gear 5 are all made of straight-tooth tooth
Wheel can convey liquid from the rear side of gear pair occlusion place to front side when two gears rotate；Driving gear 4 and driving
The shaft of motor 7 connects；There are gaps between driving gear 4 and driven gear 5 and the cavity lateral of the pump housing 6, for liquid flow
It is dynamic；
Hollow contact pin 201 is connected on end cap 2；The contact pin 201 can be structure as a whole with end cap 2.Contact pin 201
End is as inlet 8；Contact pin 201, which can be convenient, is inserted in entire pump in cleaning solution bottle, easy to use；The root of contact pin 201
It is communicated by the fluid passage in end cap 2 with the rear side at gear pair occlusion；It is arranged contact pin protection cap 1 outside contact pin 201, prevents from inserting
The prick into human body when not in use of needle 201；
Liquid outlet 9 is equipped in 6 side of the pump housing；The liquid outlet 9 is communicated with the front side at gear pair occlusion.
In use, the pump is inserted in cleaning solution bottle；Under the driving of driving motor, pass through driving gear 4 and driven tooth
The rotation of wheel 5, from gear pair rear side to front side transmitting and compressed liquid to form the fluid pressure and flow of setting；The pump phase
For the electric jet pump of other types in the market, 45% or more the cleaning solution flow enhancement of output；Miniature DC motor is also significant
Reduce current drain；
More preferably, sealing ring 3 is equipped between end cap 2 and the pump housing 6, the sealing ring 3 is located at the type chamber periphery one of the pump housing 6
It encloses and improves leakproofness with the direct injection molding of the pump housing 6 and ensure long term seal overstability.Sealing ring 3 can prevent the pump housing 6
Interior liquid leakage.
In addition, the side on the pump housing 6 is additionally provided with the second bolt hole 602；It is used for entirely pumping to be fixedly mounted.
