Description
Technical field
The utility model relates to a kind of diaphragm fluid pumps, particularly relate to a kind of leakage preventing mechanism of diaphragm fluid pump.
Background technique
Diaphragm type liquid pump is circular motion to be provided by motor, then so that the diaphragm in liquid pump is done reciprocating fortune by mechanical device
It is dynamic, to compress, stretch air in pump chamber, under the action of check valve sheet, in apopore or water inlet and ambient atmosphere
Pressure difference is generated between pressure, under the action of pressure difference, hydraulic pressure is entered into water inlet, then be discharged from water outlet.This diaphragm fluid pump is
It is well used in occasions such as small household appliances, medical instruments.Since the water entered in diaphragm fluid pump has certain pressure, this
The liquid with certain hydraulic pressure can voluntarily come out from water inlet end to water outlet water clock in liquid air pump inoperative a bit, and it is existing to generate leak
As.
In view of this, the present inventor develops a kind of leakage preventing mechanism of avoidable diaphragm fluid pump leak thus.
Utility model content
A kind of leakage preventing mechanism of diaphragm fluid pump is provided the purpose of the utility model is to overcome the deficiencies in the prior art, is kept away
Exempt to generate drainage when diaphragm fluid pump does not work.
In order to achieve the above objectives, the solution of the utility model is:
A kind of leakage preventing mechanism of diaphragm fluid pump comprising upper cover and the valve seat with upper cover immovable fitting, the upper cover are equipped with
Water inlet tap and faucet, the valve seat are equipped with water inlet and water outlet, are equipped in the faucet of the upper cover by steel ball and spring
The check-valves of composition, the faucet of upper cover is interior to be arranged one section of access being made of conical horn mouth and circular hole, the conical horn degree of lip-rounding
Tapered inclined-plane, is equipped with draining side channel between the top and tapered slope of the faucet, the check-valves is arranged in the faucet
Tapered slope and faucet top between.
Further, the check-valves further includes the T-type positioning plug cock of an inserted link and a top plug, and the top of the faucet is opened
Mouthful place forms the step of one with the top plug cooperation of positioning plug cock, the internal diameter of faucet greater than the spring outer diameter, spring it is interior
Diameter is greater than the inserted link outer diameter of positioning mouth stuffed, and in the tapered slope of faucet, steel ball is held on one end top of spring for the steel ball cooperation,
The positioning mouth stuffed is held on other end top, and the inserted link of the positioning mouth stuffed is inserted into spring.
Further, the upper cover and valve seat are equipped with mutually matched weld bond and welding slot, pass through ultrasonic fusing group
It loads solid.
After adopting the above structure, the leakage preventing mechanism of the utility model diaphragm fluid pump is the upper cover setting in diaphragm fluid pump by steel
The check-valves that pearl and spring are constituted makes the diaphragm fluid pump have positive self-sealing function, which is to pass through bullet
The buffer brake that the tapered slope compressing faucet of spring compressing steel ball, steel ball and faucet generates is formed, buffer brake and spring
Elastic force it is consistent.When diaphragm fluid pump does not work, hydraulic pressure is less than the buffer brake, and steel ball is motionless, and water will not be flowed out from faucet,
Avoid drainage；When diaphragm fluid pump work, hydraulic pressure is greater than this buffer brake, and steel ball is just rushed to open, and liquid can just flow out.Make
Can have certain cracking pressure from its water inlet end to water outlet with the diaphragm fluid pump of the utility model leakage preventing mechanism, can prevent
The liquid of certain hydraulic pressure voluntarily comes out from water inlet end to water outlet water clock in liquid air pump inoperative, drags all-in-one machine especially suitable for sweeping
Small flow drip wet rag purposes, the phenomenon that water liquid passes through liquid pump water dripping in water tank when avoiding not working.
Detailed description of the invention
Fig. 1 is the combination stereogram of the utility model preferred embodiment.
Fig. 2 is the cross-sectional view of the utility model preferred embodiment.
Specific embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
It as shown in Figures 1 and 2, is the second preferred embodiment of the leakage preventing mechanism of the utility model diaphragm fluid pump, this implementation
In example, the leakage preventing mechanism of the diaphragm fluid pump includes upper cover 1 and the valve seat 2 with 1 immovable fitting of upper cover, and the upper cover 1 is equipped with water inlet
Mouth 11 and faucet 12, the valve seat 2 are equipped with water inlet 21 and water outlet 22, are equipped in the faucet 12 of the upper cover 11 by steel
The check-valves 4 that pearl 41 and spring 42 are constituted.
One section of access 13 being made of conical horn mouth and circular hole, conical horn mouth are set in the faucet 12 of the upper cover 1
Tapered slope 14 is formed, draining side channel 15 is equipped between the top and tapered slope 14 of the faucet 12, the check-valves 4 is arranged
Between 12 top of tapered slope 14 and faucet of the faucet 12.
In the present embodiment, the check-valves 4 is in addition to further including an inserted link 43 and top 44 structures of plug with steel ball 41 and spring 42
At T-type position plug cock 45, the platforms of one with 44 cooperation of top plug of positioning plug cock 45 are formed at the top end opening of the faucet 12
Rank 121, the internal diameter of faucet 12 are greater than the outer diameter of the spring 42, and the internal diameter of spring 42 is greater than outside the inserted link 43 of positioning mouth stuffed 45
Diameter, the cooperation of steel ball 41 is in the tapered slope 14 of faucet 12, and steel ball 41 is held on one end top of spring 42, and institute is held on other end top
Positioning mouth stuffed 45 is stated, the inserted link 43 of the positioning mouth stuffed 45 is inserted into spring 42.
The leakage preventing mechanism of the diaphragm fluid pump of the present embodiment is the upper cover setting check-valves 4 in diaphragm fluid pump, makes the diaphragm liquid
Pump has positive self-sealing function, which is to oppress steel ball 41, steel ball 41 and faucet 12 by spring 42
Tapered slope 14 oppress faucet 12 generate buffer brake formed, buffer brake is consistent with the elastic force of spring.When diaphragm liquid
When air pump inoperative, hydraulic pressure is less than the buffer brake, and steel ball is motionless, and water will not be flowed out from faucet or water outlet, avoids leak existing
As；When diaphragm fluid pump work, hydraulic pressure is greater than this buffer brake, and steel ball is just rushed to open, and liquid can just flow out.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
