Description

Miniature diaphragm pump upper end cover
Technical field:
The invention belongs to pump equipment field, particularly a kind of Miniature diaphragm pump upper end cover.
Background technology:
Miniature diaphragm pump (RO pumps) is also referred to as RO booster pumps, RO self priming pumps, reverse osmosis booster pump, counter-infiltration self priming pump etc., is One kind of DC diaphragm booster pump.The English name of RO pumps is Reverse Osmosis Diaphragm Pump, complete Chinese meaning Think of is counter-infiltration (reverse osmosis) diaphragm booster pump.It is currently one of water purification industry, the core part of domestic water purifying machine.
At present, RO pumps are larger in the presence of vibrating in use, and noise is also larger, and prior art is used in RO pump heads Outer side of lid sets the damping and silencing device such as A of Publication No. CN 104776014, the public affairs of entitled water purifier and its bellows pumping element Open " a kind of bellows pumping element of water purifier, it is characterised in that including:The pump housing, the pump housing has water side;Damping unit, institute Stating damping unit includes:First housing, first housing has water inlet, and the water inlet is connected with the water side;The Two housings, second housing has a delivery port, second housing be connected with first housing and with first housing Cushion space is limited, wherein the cushion space is connected with the water inlet and the delivery port respectively;Damping piece, the resistance Damping member is located in the cushion space and by hydraulic drives elastic deformation.", but this mechanism structure is complicated, and parts are more, into This is higher, and assembles also cumbersome.
The content of the invention:
It is an object of the invention to provide a kind of simple in construction, small volume, lightweight, parts are less, easy to assembly, can subtract Shake de-noising, enhancing emptying suction capacity and can be greatly reduced processing and installation cost Miniature diaphragm pump upper end cover.
The present invention is to solve the above problems, provide a kind of Miniature diaphragm pump upper end cover, and it includes covering in miniature diaphragm pump head Intake antrum and water chamber are provided with the lid in portion, the lid, and the both sides of lid are respectively equipped with water inlet pipe and outlet pipe, it is described Water inlet pipe is connected with intake antrum, and outlet pipe is connected with water chamber, causes miniature diaphragm pump head provided with water fender in the water chamber The water outlet of portion water side will not be entered directly into outlet pipe.
Compared with prior art, the present invention provided with water fender in water chamber due to causing miniature diaphragm head water side Water outlet will not be entered directly into outlet pipe, then water fender can separate the current flowed back in the water outlet of water side and outlet pipe, To reduce the mutual impact of current, so as to reduce vibration and noise;And water fender also causes the water outlet of water side to obtain one Entered back into after fixed buffering in outlet pipe so that the bubble in current is greatly decreased, the current of water outlet also more smooth out it is more stable, So as to reduce impact of the current to pipeline, to reduce vibration and noise, and emptying water pump ability and pump can be also greatly improved The full rate of water in cavity, so as to reach the suction capacity and initial water outlet efficiency of enhancing water pump;Furthermore whole mechanism structure letter Single, small volume is lightweight, and parts are less, can single injection-molded, eliminate assembly program, thus be greatly reduced processing and Installation cost.Therefore the present invention have simple in construction, small volume, less, easy to assembly lightweight, parts, damping de-noising, The characteristics of enhancing empties suction capacity and processing and installation cost can be greatly reduced.
Preferably, being provided with annular protrusion in the lid, the annular protrusion is partitioned into intake antrum and water chamber, described Water chamber is located in annular protrusion;The water fender is arcuate structure, and water fender is located at outlet pipe and water chamber connectivity part Front;After then so setting, structure is simpler, also allows for injection molding, and demoulding success rate is also higher.
Preferably, the corresponding center of circle of the water fender is overlapped with the center of circle of annular protrusion, the center of the water fender exists On the extended line of outlet pipe axis;After then so setting so that the current of water fender both sides are relatively more uniform, current flow into water outlet Pipe is also more smoothed out, and vibration is also relatively small, and noise is also decreased.
Preferably, the corresponding central angle of the water fender is 90~120 °;It is relative in this scope internal vibration and noise It is smaller, such as larger than 120 °, then cause water outlet cavity pressure larger, be easily caused end cap and deform, such as less than 90 °, then to current rectification Effect it is poor, vibration and noise with it is existing almost equal.
Preferably, the corresponding central angle of the water fender is 100 °.
Preferably, the both sides of the lid are equipped with the protective cover of " C " font, two protective covers correspond to water inlet pipe respectively And outlet pipe, the axis of the water inlet pipe and the axis of outlet pipe are overlapped with the axis of each self-corresponding protective cover;Then so set Postpone, protective cover can protect the snap joint of pipeline, water inlet pipe and go out while also protection water inlet pipe and outlet pipe, when preventing from dropping Water pipe is broken because of collision, so as to ensure the stability in use of the present invention.
Preferably, the corresponding central angle of the protective cover is 120~135 °;Protective cover is to entering when then in the range of this The protection of water pipe and outlet pipe is relatively more preferable.
Preferably, the corresponding central angle of the protective cover is 130 °.
Preferably, the axial length of the water inlet pipe and the axial length of outlet pipe subtract each self-corresponding protective cover The value of axial length is 0~5mm;After then so setting, on the premise of water inlet pipe and outlet pipe stability in use is ensured, may be used also So that snap joint can be dismounted quickly and easily with water inlet pipe and water outlet pipe.
