Technical field
The present invention relates to a kind of Miniature diaphragm pump and its valve member.
Background technology
Miniature diaphragm pump is a kind of conveying equipment for fluid substances, and its pump housing is provided with diaphragm and is used for driving diaphragm back and forth to transport
Dynamic drive mechanism；Influent stream chamber in the pump housing is connected by the pump chamber that diaphragm is divided into in the pump housing respectively with outflow lumen.Miniature
Membrane pump changes the action of diaphragm by its drive mechanism, makes the diaphragm difference in the diaphragm and outflow lumen in influent stream chamber
Toward contrary direction motion, form the synchronous reciprocating motion of two diaphragms, it is achieved thereby that the suction of fluid and discharge.Please be same
When refer to Fig. 1 and Fig. 2, the structure that existing diaphragm 11 adopts is flat sheet rubber, then when Miniature diaphragm pump draws water, rubber
The surface of piece needs just to the port sealing its direction, but due to there is impurity in water, then the influent stream rubber in influent stream chamber
Piece and be located in outflow lumen go out to flow sheet rubber certain obstruction can be caused to the flowing of impurity, so that impurity cannot be entered simultaneously with water
Enter in outflow lumen and flow out from outflow lumen, and impurity can build up leading between influent stream sheet rubber and influent stream chamber and pump chamber
Mouthful place, go out to flow the passage port between sheet rubber and pump chamber, lead to influent stream sheet rubber with go out to flow sheet rubber cannot deadend and its
Corresponding port, causes the suction capactity of Miniature diaphragm pump to decline；Meanwhile, the impurity of accumulation also can cause to hinder to current flowing
Hinder, so that current is flowed slow.And, sheet rubber is easily aging, and aging sheet rubber is frangible and can come off and accumulate turn of tidal stream mouth
In, result in blockage, hinder current to pass through, cause Miniature diaphragm pump to be scrapped.
In view of this, how to provide a kind of membrane configuration, make the suction capactity of Miniature diaphragm pump not be subject to impurity effect, and energy
Enough realize the prolongation of the service life of Miniature diaphragm pump, be those skilled in the art's technical issues that need to address.

To during motion, the gas in brake chamber 43 is extracted, and its internal pressure is less than outside pressure, is realized to outside stream using pressure reduction
The suction of body source, now, influent stream valve ball 442 is pushed (the first back-moving spring 441 and is opened between influent stream chamber 41 and brake chamber 43
Port, makes influent stream chamber 41 connect with brake chamber 43, outflow valve ball 452 tightly seals up between outflow lumen 42 and brake chamber 43 simultaneously
Port, so that outflow lumen 42 is not connected with brake chamber 43, thus realize external source of fluid is drawn in brake chamber 42.Work as connecting rod
When moving in the past direction towards brake chamber 43 of 33 drive pump core 31, namely to propelling gass in brake chamber 43, its internal pressure
More than outside pressure, it is transported to the external world using the fluid source that pressure reduction realizes suction is come in, now, influent stream valve ball 442 is subject to bullet
Spring force effect and differential pressure action Rapid reset, tightly seal up the port between influent stream chamber 41 and brake chamber 43, make influent stream chamber
41 are not connected with brake chamber 43；Outflow valve ball 452 is pushed second back-moving spring 451 and is opened outflow lumen 42 and brake chamber 43 simultaneously
Between port, so that outflow lumen 42 is connected with brake chamber 43, thus realize the fluid in brake chamber 43 is pushed to outflow lumen 42
In, and flow out it is achieved that exporting the fluid of suction the external world from outflow lumen 42.Then, according to above-mentioned work process, pass through
Connecting rod 33 constantly moves reciprocatingly, and changes the pressure of brake chamber 43, by the use of pressure reduction as driving influent stream valve ball 442 and outflow valve
The power of ball 452 work, makes influent stream valve ball 442 and outflow valve ball 452 synchronously does reciprocating motion in opposite direction it is achieved that right
The suction of fluid and output.Influent stream valve ball 442 and outflow valve ball 452 all adopt sphere structure, are made miscellaneous using the rollability of spheroid
Light weight is changed places and is entered in outflow lumen 42 and flow out outflow lumen 42 with the valve ball rolling, it is to avoid the accumulation in passage port for the impurity,
Ensure that the unobstructed of fluid motion, utilize the cooperation of spheroid and circular port simultaneously, realize the deadend to port for the valve ball, protect
The flow of card fluid.And the valve ball structure of sphere structure is more solid than sheet rubber, non-aging, long service life.
In addition, the present invention also has other variant embodiment, such as:
(1) lay protecting film in described tabletting 32 top surface, that is, protection is fitted tightly over the top surface of tabletting 32.Set herein
Putting and advantageously ensuring that Miniature diaphragm pump works long hours is not in that tabletting 32 ftractures, aging, the phenomenon such as come off.
(2) described tabletting 32 is metal sheeting.It is provided with herein and be beneficial to be further ensured that Miniature diaphragm pump works long hours
Be not in that tabletting 32 ftractures, aging, the phenomenon such as come off.
With respect to prior art, Miniature diaphragm pump of the present invention and its valve member avoid impurities accumulation to influent stream chamber and system
Passage port between dynamic chamber, it also avoid impurities accumulation to the passage port between outflow lumen and brake chamber simultaneously, and avoid because
The self-adhesion of turn of tidal stream main body and lead to pump tool lost efficacy, enhance suction and the discharge ability of Miniature diaphragm pump convection cell, protect
Demonstrate,prove smoothness and the flow of fluid operation, extend service life.
