Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figs 1-4, it is the schematic diagram of the utility model micro pump embodiment, which can be applied to electronics
In electric equipment products, craftwork (such as aquarium, landscape pond etc.), mechanical equipment, to realize that the fluid in relevant device drives
Or fluid circulation.
First check valve 113, second of the micro pump including housing 1 and in housing 1 in the present embodiment is unidirectional
Valve 114, coil 115 and permanent magnet 116；Wherein, it is located at going out for flow chamber both ends in above-mentioned housing 1 with flow chamber and respectively
Liquid mouth 111 and inlet 112；Coil 115 is installed on housing 1 and the magnetic field of alternation is generated when being powered in flow intracavitary；The
One check valve 113 and the second check valve 114 are respectively installed in flow intracavitary and are unidirectionally opened under the pressure of unidirectional fluid
It opens (such as under pressure of the fluid in Fig. 2 from bottom to top), and formed between the first check valve 113 and the second check valve 114
The pressure chamber of closing；Permanent magnet 116 is fixed on the second check valve 114, and the second check valve is driven under action of alternating magnetic field
114 (or parts of the second check valve 114) do reciprocal linear motion in the flow intracavitary of housing 1.
Above-mentioned micro pump drives the second check valve 114 to do straight reciprocating motion by permanent magnet 116, and unidirectional second
Open successively the second check valve 114 and the first check valve 113 in 114 motion process of valve：Such as in fig. 2, in permanent magnet 116
When driving the second check valve 114 to move downward, the second check valve 114 is opened under the pressure effect of the fluid from inlet 112
It opens (the first check valve 113 remains turned-off at this time), it is unidirectional that the fluid from inlet 112 enters the first check valve 113 and second
Pressure chamber between valve 114；When permanent magnet 116 drives the second check valve 114 to move upwards, which is pressing
The pressure effect of power cavity fluid is lower to close, and the first check valve 113 is opened under the pressure effect of pressure cavity fluid, pressure
The fluid of intracavitary is flowed out by liquid outlet 111.Repeatedly above to act, liquid will be from inlet 112 endlessly from liquid outlet
111 outflows, it is achieved thereby that the function of liquid conveying, it is defeated that without rotor, impeller and impeller cavity fluid can be realized in whole process
It send, substantially reduces the volume of water pump.
Above-mentioned first check valve, 113 and second check valve 114 can be located on same axis.By this way, can directly by
Liquid supplying passage pressurizes to fluid without exceptional space, further reduces micro pump as pressurization space
Volume.
Particularly, above-mentioned flow chamber, inlet 112 and liquid outlet 111 can be located on same axis, miniature so as to be conducive to
The installation (such as above-mentioned micro pump can be installed directly on the straightway of associated cyclic system) of water pump and reduction body
Product.
Can have independently of flow chamber and around the coil bore of flow chamber on above-mentioned housing 1, coil 115 is installed in the coil
Intracavitary.With this configuration, uniform magnetic field can be formed, and the liquid of flow intracavitary will not cause shadow to coil 115 in flow intracavitary
It rings.And flow chamber and the separated structure of coil bore are additionally favorable for the assembling of the first check valve 113 and the second check valve 114 and close
It closes.
Specifically, above-mentioned housing 1 may include upper cover 119, lower cover 120, coil holder 118 and outer cover 117, and wherein coil holder 118 is
Columnar structured, upper cover 119 and lower cover 120 are respectively installed in the both ends of coil holder 118, so as to flow chamber by coil holder 118 inner wall,
Upper cover 119, lower cover 120 enclose；Coil bore is then enclosed by the inner wall of the outer wall of coil holder 118 and outer cover 117.
As shown in figure 3, permanent magnet 116 first can be installed to the second check valve 114 by above-mentioned micro pump in assembling；So
Afterwards respectively by the first check valve 113 and the second check valve 114 from the upper/lower terminal of coil holder 118 on coil holder 118, and by coil
115 are installed to the outer wall of coil holder 118；It, will be outer after upper cover 119 and lower cover 120 are assembled into the upper/lower terminal of coil holder 118 respectively
Cover 117 is assembled into the outer wall of coil holder 118, while upper cover 119 and lower cover 120 are fixed；Finally, wire connection terminal 121 assembles
To the winding overhang of coil 115, above-mentioned wire connection terminal 121 is for connecting power supply, so that coil 115 generates magnetic in flow intracavitary
.
As shown in figure 4, above-mentioned second check valve 114 include fixed disk 1141, elastic joint part 1142, sliding sleeve 1143 with
And spool 1144；Above-mentioned elastic joint part 1142 can be made of film, above-mentioned sliding sleeve 1143 by elastic joint part 1142 with
Fixed disk 1141 is connected；Permanent magnet 116 is mounted on sliding sleeve 1143 and sliding sleeve 1143 is driven to be relatively fixed disk 1141 and does directly
Line moves back and forth；Spool 1144 then follows that sliding sleeve 1143 does straight reciprocating motion and spool 1144 is only in the Fluid pressure of side
It is opened during more than preset value.When being installed to housing 1, fixed disk 1141 is fixed between one end of coil holder 118 and lower cover 120,
Sliding sleeve 1143 then extend into 118 inside of coil holder (for ease of assembling, the end of coil holder 118 can have flange arrangement).Particularly,
Above-mentioned spool 1144 can be located in sliding sleeve 1143.Permanent magnet 116 is in circular ring shape, and is placed on the periphery of sliding sleeve 1143.
The spool 1144 of above-mentioned second check valve 114 can be made of rubber material；The spool 1144 may include section for cone
The main body of shape, and in the inside of main body (lower section of section as shown in Figure 2 for the main body of taper) there is water stream channel, top to have
There is notch.Above-mentioned notch is in normally off, and the Fluid pressure only in water stream channel is opened when being more than preset value, and second is single at this time
Opened to valve 114, and the pressure in water stream channel do not reach preset value when, then the notch remains turned-off.Due to spool 1144
Main body section is taper, therefore above under the pressing aid on two inclined-planes, which can not open when pressure is larger above, prevent
Fluid countercurrent current.
The spool of first check valve 113 can be used and 1144 same structure of the spool of the second check valve 114.
For ease of processing and manufacturing, fixation disk 1141, elastic joint part 1142, the sliding sleeve of above-mentioned second check valve 114
1143 can also be made of rubber material, and fixed disk 1141, elastic joint part 1142, sliding sleeve 1143 and 1144 one of spool,
And the different function of each section is realized by the thickness of rubber material, such as elastic joint part 1142 has smaller thickness,
It is moved so that sliding sleeve 1143 can be relatively fixed disk 1141；Fixed disk 1141 and sliding sleeve 143 have larger thickness, to protect
Demonstrate,prove structural strength.
Repeatedly above to act, liquid endlessly will export outflow from 120 entrance of lower cover from upper cover 119.So as to fulfill
The function of liquid conveying.
The utility model also provides a kind of fluid circulation system, including micro pump as described above, passes through the Miniature water
Pump realizes fluid pressurization, so as to form liquid circulation.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, can be readily occurred in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
