Description
Technical field
The utility model relates to electronic water pump for automobile technical field, specifically a kind of electronic water pump for automobile flow blocking machine
Structure.
Background technique
Currently, electronic water pump is widely used in new-energy automobile, caravan and special vehicle, play as water circulation,
Cooling or water system effect.Its principle is that the diaphragm inside water pump is made to do reciprocating by mechanical device, to press
Contracting, the air stretched in pump chamber form positive pressure under unidirectional valve action at discharge outlet；Vacuum is formed at pump mouth, thus
Pressure difference is generated between external atmosphere pressure, under the action of pressure difference, hydraulic pressure is entered into water inlet, then be discharged from discharge outlet.
Generally, electronic water pump at work, is acted on liquid by impeller of rotor, and it is empty that liquid is transported to water pump conveying
In chamber, when water pump stops working, liquid will flow backward in the conveying cavity of water pump under the effect of gravity, so that reflux is formed,
Liquid need to be covered with again to pump housing space in lower task, discharge air could work normally, and substantially reduce electronic water pump
Working efficiency.
Summary of the invention
In order to avoid with solve above-mentioned technical problem, the utility model proposes a kind of electronic water pump for automobile flow blocking mechanisms.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of electronic water pump for automobile flow blocking mechanism, including impeller of rotor, water pump upper cover, the upper surface of the impeller of rotor are set
There are the first ring convex being distributed with one heart to rise to rise with the second ring convex, first ring convex rise, constitute flow blocking annular groove between the second ring convex,
The lower end surface of the water pump upper cover is equipped with the third ring convex between flow blocking annular groove and rises, and second ring convex rise and protrude into flow blocking
In annular groove and make to constitute wavy runner between impeller of rotor and water pump upper cover.
Further, the diameter that first ring convex rise is greater than the diameter that the second ring convex rise.
Further, the third ring convex act the center that flow blocking annular groove is arranged in.
Further, slope surface of the flow blocking annular groove bottom equipped with the radial direction along impeller of rotor obliquely.
The beneficial effects of the utility model are: the conveying cavity inside of electronic water pump can be formed wave by the utility model
The flow blocking runner of shape effectively avoids conveying liquid reflux, greatly improves the working efficiency of electronic water pump, has that structure is simple, makes
With the strong advantage of convenient, anti-return ability.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure composition cross-sectional view of the utility model；
Fig. 2 is partial enlarged view at the I of Fig. 1；
Fig. 3 is the structural schematic diagram of impeller of rotor in the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
It is further described in face of the utility model.
As shown in Figure 1 to Figure 3, a kind of electronic water pump for automobile flow blocking mechanism, including impeller of rotor 1, water pump upper cover 2, it is described
The upper surface of impeller of rotor 1 is equipped with that the first ring convex for being distributed with one heart play 1a and the second ring convex play 1b, and first ring convex play 1a, the
Two ring convex rise and constitute flow blocking annular groove 3 between 1b, and the lower end surface of the water pump upper cover 2 is equipped with the between flow blocking annular groove 3
Tricyclic protrusion 2a, second ring convex play 1b and protrude into flow blocking annular groove 3 and make to constitute wave between impeller of rotor 1 and water pump upper cover 2
The runner of shape wave.
The diameter that first ring convex play 1a is greater than the diameter that the second ring convex play 1b.
The third ring convex play the center that flow blocking annular groove 3 is arranged in 2a.
Slope surface 3a of 3 bottom of flow blocking annular groove equipped with the radial direction along impeller of rotor 1 obliquely.
In use, since the first ring convex play 1a, the second ring convex play 1b and third ring convex play the presence of 2a, in impeller of rotor
The runner constituted between 1 and water pump upper cover 2 moves towards wavy, while the fit clearance based on impeller of rotor 1 and water pump upper cover 2
Slope surface 3a on smaller and flow blocking annular groove 3, after closing, liquid can not be passed through from flow blocking annular groove 3 water pump under self gravity
It crosses, to play the role of anti-backflow.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model also has
Various changes and modifications, these changes and improvements are both fallen in claimed invention.The requires of the utility model protection
Range is defined by the appending claims and its equivalent thereof.
