And between pump cover 12, and, this flange 112 also has waterproof sealing function, prevents the liquid in chamber 105 from spilling.
In one embodiment, as it is shown in figure 1, flange 112 is not only provided at the periphery of barrier film 11, flange 112 also extends
To the 4th fluid course the 1056, the 5th fluid course 1057, enter accent 1051 and go out the periphery of accent 1052 correspondence position, phase
Ying Di, the line of rabbet joint 120 and the line of rabbet joint 109 extend to the 4th fluid course the 1056, the 5th liquid the most respectively on pump cover 12 and main part 10
Circulation road 1057, enter accent 1051 and go out the position that the periphery of accent 1052 is corresponding, so that flange 112 is to whole chamber
The periphery of 105 seals.
In one embodiment of the invention, the mode of the volume size that drive mechanism 2 changes chamber 105 is: drive machine
Structure 2 is connected with barrier film 11, and drive mechanism 2 occurs reciprocating motion to change the volume size of chamber 105 by driving barrier film 11.
The structure of drive mechanism 2 can have multiple, and the structure of the drive mechanism 2 of the present embodiment is as follows:
Incorporated by reference to refering to Fig. 1 to Fig. 4, drive mechanism 2 includes motor 21, eccentric 22 and the connecting rod being arranged in main part
23, eccentric 22 is arranged on the output shaft 210 of motor 21, and connecting rod 23 is socketed in outside eccentric 22, the end of connecting rod 23 with every
The side away from pump cover 12 of film 11 connects, and by the eccentric rotary of eccentric 22, drivening rod 23 moves back and forth, thus carries
Dynamic barrier film 11 moves back and forth.
For example, as shown in Figure 4, the middle part of connecting rod 23 defines a kidney slot 232, and the waist of waist type groove 232 is parallel
Plane in barrier film 11 place.Eccentric 22 is positioned at waist type groove 232, in eccentric 22 rotation process, away from the one of the point of rotation
Side is expressed to the inwall of one of them waist of the waist type groove 232 of connecting rod 23, thus promotes this waist place end of connecting rod 23 that court occurs
Move to chamber 105.
Wherein, motor 21 can be brushless electric machine, and the interference of brushless electric machine is low, noise is low, and smooth movements, uses the longevity
Life is long, the most also has the advantage that maintenance cost is low.
Specifically, the connected mode of connecting rod 23 and barrier film 11 has multiple, and the most bonding, clamping etc. the following is the present embodiment
Connected mode between middle connecting rod 23 and barrier film 11:
Barrier film 11 is provided with groove 110, and the edge of groove 110 is provided with inwardly projecting chuck 111, the end of connecting rod 23
Being provided with nose bar 230, the end of nose bar 230 is provided with barb 231, and nose bar 230 inserts in groove 110, by barb 231 and chuck
The cooperation of 111 and connecting rod 23 is coupled together with barrier film 11.
In one embodiment, barrier film 11 is provided with a groove 110, and the end of connecting rod 23 is correspondingly provided with a nose bar
230。
In another embodiment, in order to make the connection of barrier film 11 and connecting rod 23 more fasten, barrier film 11 is provided with two
Groove 110, the end of connecting rod 23 is correspondingly provided with two nose bars 230.
Owing to connecting rod 23 is connected with barrier film 11 by two nose bars 230 so that on barrier film 11, the stress of each several part more becomes
In equilibrium, so that the motion of barrier film 11 each several part more tends to synchronizing, so that the volume of cavity 105 is with the rotation of motor 21
And the change that occurs is sensitiveer, and then liquid is carried or the speed of supercharging is more accelerated with the rotation of motor 21.
Being further fixed on circuit board 14 on the pump housing 1, circuit board 14 is connected with pressure-detecting device 3 and flow detector 4, uses
In receiving pressure-detecting device 3 and the feedback result of flow detector 4, and feedback result is passed to control terminal.Control eventually
Flow and the pressure of liquid can be controlled by end according to this feedback result.
The pump housing 1 also include side cover 15, side cover 15 be arranged on main part 10, near the side of circuit board 14 position,
Wire hole 150 it is additionally provided with, for drawing the wire on circuit board 14 on side cover 15.
In one embodiment, in order to waterproof, the pump housing 1 farther includes be sheathed on outside drive mechanism 2 and be fixed on master
Capsul 13 on body 10.
It is noted that in certain embodiments, the pump housing 1 only includes a chamber 105, and in other embodiments
In, the pump housing 1 includes two chambers 105.
In the case of the pump housing 1 includes two chambers 105, drive for convenience, the opposite sides of main part 10 is divided
It is not provided with one group of pump cover 12 and barrier film 11, and then is symmetrically formed chamber 105 in the opposite sides of main part 10, as shown in Figure 4, for
Making a distinction these two chambers 105, to facilitate, the present invention will be described, chamber above in Fig. 4 is chamber
1058, the chamber being positioned at lower section is chamber 1059, and barrier film above is barrier film 113, and the barrier film being positioned at lower section is barrier film
114。
Drive mechanism 2 is arranged between two barrier films 11, and then drives two barrier films 11 to do adverse movement simultaneously.
What the first fluid course 103 was arranged on two chambers 105 enters between accent 1051, and the second fluid course 104 is arranged
Going out between accent 1052 at two chambers 105.
Below by combining Fig. 1 to Fig. 4, the operation of the pump of this embodiment is introduced:
Liquid enters the first fluid course 103 from inlet 101.
The side away from the point of rotation of eccentric 22 extrude the waist type groove 232 of connecting rod 23 in the diagram be positioned in figure lower section
Waist inwall on, now, eccentric 22 drivening rod 23 moves downward so that barrier film 114 extrudes to chamber 1059, reduce chamber
