Description
Technical field
The utility model relates to a kind of micro pump structures.
Background technique
Micro pump currently on the market is widely used on the market due to small, low noise, low in energy consumption.It is main
It is persistently to form vacuum or negative pressure in water inlet and pull water out.Due to the tension of water surface, hold in water inlet
Moisture film is easily formed, so that water pump dallies and do not take out water, water pump failure is will lead to, seriously affects the normal operation of machine, become
One big technology puzzlement.
Utility model content
The utility model provides a kind of micro pump structure, and which overcome the existing deficiencies of background technique.This reality
Used technical solution with novel its technical problem of solution is:
A kind of micro pump structure, it is characterised in that: it includes pump chamber, the motor being installed in pump chamber, dress
It connects in pump chamber and is sequentially connected the impeller of motor and lid connects pump cover in pump chamber, pump cover offers water inlet, water
Pump housing offers water outlet, and the side of impeller towards pump cover is convexly equipped with the protrusion that can break through moisture film, and protrusion stretches to
Water inlet.
Among one preferred embodiment: protrusion is cylinder, and its end and the lateral surface of water inlet are flush.
Among one preferred embodiment: protruding parts is in impeller towards the center of pump cover side.
Among one preferred embodiment: protrusion number set there are two and arranged for interval.
Among one preferred embodiment: there are three protrusion number is set and annular space is arranged.
Among one preferred embodiment: being provided with the first magnetic induction coil at the top of impeller, motor is provided with second line of magnetic induction
Circle is cooperated by the induction of the first magnetic induction coil and the second magnetic induction coil impeller and motor to be driven.
The technical program compared with the background art, it has the following advantages:
1. water enters from the inlet in pump chamber, negative pressure is formed by impeller and is flowed out again from water outlet, due to water surface
Tension, moisture film can be formed on the inside of water inlet, and be convexly equipped with the protrusion that can break through moisture film in the side of impeller towards pump cover,
And protrusion stretches to water inlet, the protrusion can stave moisture film when wheel rotation, enable water pump normal pumping.The water pump
Structure only adds protrusion on the basis of original structure, is not only simple in structure, and has the effect of significantly breaking through moisture film, fits
Close a wide range of promote the use of.
2. protrusion is cylinder, and its end and the lateral surface of water inlet are flush, which does not protrude water inlet
Lateral surface, so that water pump contour structures do not generate change, suitability is strong.
3. protruding parts in impeller towards the center of pump cover side so that protrusion carries out when breaking through moisture film from moisture film center
It breaks through, breakthrough effect is good, will not secondary formation moisture film.
4. protrusion number set there are two and arranged for interval so that it is more stable into the water in pump chamber, balance, no
Abnormal sound can be generated.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 depicts the perspective exploded view of the micro pump of a preferred embodiment.
Fig. 2 depicts the schematic cross-sectional view of the micro pump of a preferred embodiment.
Fig. 3 depicts the structural schematic diagram of the impeller of a preferred embodiment.
Specific embodiment
Please refer to Fig. 1 to Fig. 3, an a kind of preferred embodiment of micro pump structure, a kind of micro pump structure,
It includes pump chamber 10, motor, impeller 20 and pump cover 30.
As shown in Figure 1, the bottom surface of pump chamber 10 is openning shape, top surface offers water outlet 11.Motor (does not show in figure
It is installed in pump chamber 10 out).
Impeller 20 is installed in pump chamber 10 and transmission connection motor, and the side of impeller 20 towards pump cover 30, which is convexly equipped with, to dash forward
The protrusion 21 of one's water breaks film.
In the present embodiment, protrusion 21 is located at center of the impeller 20 towards 30 side of pump cover, so that protrusion 21 breaks through water
It is broken through when film from moisture film center, breakthrough effect is good, will not secondary formation moisture film.
In the present embodiment, protrusion 21 is cylinder, and its end and the lateral surface of water inlet 31 are flush, so that outside water pump
Shape structure does not generate change, and suitability is strong.
In the present embodiment, 21 numbers of protrusion set there are two and arranged for interval so that more into the water in pump chamber
Stablize, balance, abnormal sound will not be generated.Alternatively, 21 numbers of protrusion set there are three and annular space arrange.It can also be by protrusion 21
Number is set as four, five and differs, and is not limited.
In the present embodiment, the first magnetic induction coil 22 is provided at the top of impeller 20, motor is provided with the second magnetic induction coil,
Cooperated by the induction of the first magnetic induction coil 22 and the second magnetic induction coil impeller 20 to be driven with motor.
The lid of pump cover 30 connects in pump chamber 10, and pump cover 30 offers water inlet 31, and protrusion 21 stretches at water inlet 31.
Water enters in pump chamber 10 from water inlet 31, forms negative pressure by impeller 20 and flows out again from water outlet 11, due to
The tension of water surface can form moisture film on the inside of water inlet 31, and be convexly equipped with and can break through in the side of impeller 20 towards pump cover 30
The protrusion 21 of moisture film, and protrusion 21 stretches at water inlet 31, the protrusion 21 can stave moisture film when impeller 20 rotates,
Enable water pump normal pumping.The water pump structure only adds protrusion on the basis of original structure, is not only simple in structure, and have
The apparent effect for breaking through moisture film, is suitable for large range promotion use.
This micro pump can be used on the electronic products such as air-cooler, humidifier.
The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented
It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual
In the range of type covers.
