Embodiment
Water purifier of the present utility model is for purifying tap water etc., water purifier has a casing, casing is provided with into water port and water outlet port, and in casing, be provided with multi-stage filter core and stabilized pressure pump, tap water flows to water purifier from water inlet port, through the filtration of multi-stage filter core, and after the voltage stabilizing of stabilized pressure pump, flow out from water outlet port.
Referring to Fig. 5, in stabilized pressure pump, be provided with pedestal 40, the housing 30 of stabilized pressure pump is arranged on pedestal 40, and between housing 30 and pedestal 40, water outlet pressure plate 41 and diaphragm 50 is installed.Housing 30 is provided with a through hole 61, is provided with tapped hole 62 in pedestal 40, and screw 60 passes through hole 61 and screws in tapped hole 62, thus housing 30 is fixed on pedestal 40.
Referring to Fig. 6, the peripheral region of housing 30 is provided with perisporium 35, and the lower surface 31 of housing 30 diapires is roughly plane, and lower surface 31 extends to form a circle flange 32 in the direction of diaphragm 50, and flange 32 is along the circumferential extension of housing 30, and flange 32 is annular.As seen from Figure 6, flange 32 is positioned at lower surface 31 near perisporium 35 places.
On the outer surface 33 of the end of perisporium 35, be also provided with flange 34, flange 34 extends to diaphragm 50 directions from outer surface 33, and flange 34 is also the circumferential extension along housing 30, and flange 34 be annular.In the axial direction of housing 30, lower surface 31 is positioned on two horizontal planes of different heights with outer surface 33, and therefore flange 32 and flange 34 are to be also positioned in two different planes of different heights.
The internal surface 36 of perisporium 35 is not parallel to the axis of housing 30, but is obliquely installed with the axis of housing 30.As seen from Figure 6, in the footpath of housing 30 upwards, the thickness of perisporium 35 increases to housing 30 main bodys gradually from its end, therefore the internal surface 36 of perisporium 35 from outer end 37 to inner 38 close to the axis of housing 30 gradually.
The Fig. 5 that sees you later, perisporium 35 is D1 near the internal diameter of diaphragm 50 1 sides, and is D2 away from the internal diameter of diaphragm 50 1 sides, and inner diameter D 1 is greater than inner diameter D 2, perisporium 35 is greater than the internal diameter away from diaphragm 50 1 sides near the internal diameter of diaphragm 50 1 sides.
Referring to Fig. 7, the lower surface 42 of water outlet pressure plate 41 is provided with a circle flange 43, and flange 43 extends to diaphragm 50 directions from lower surface 42, and flange 43 is ring-type, and along the circumferential extension of water outlet pressure plate 41.The lower end of water outlet pressure plate 41 is provided with groove 44, and groove 44 upwards caves in from the lower surface of water outlet pressure plate 41, and groove 44 is near the peripheral region of water outlet pressure plate 50.In the footpath of water outlet pressure plate 41 upwards, flange 43 is positioned at the inner side of groove 44.
Referring to Fig. 8, diaphragm 50 is by having flexible material, as the materials such as rubber are made, and be arranged on pedestal 40, diaphragm 50 is provided with the diaphragm 51 of flat, the peripheral region of diaphragm 51 is provided with the flange 52 and the flange 54 that extend to housing 50 directions from diaphragm 51, in the axial direction of diaphragm 50, the height of flange 52 is greater than the height of flange 54, and in the footpath of diaphragm 50 upwards, flange 54 is positioned at the inner side of flange 52.And, between flange 52 and flange 54, be provided with groove 55.
Review Fig. 5, flange 52 is positioned on the periphery of diaphragm 50, therefore flange 52 is the perisporium of diaphragm 50, and, the perisporium 35 that the D outer diameter 3 of diaphragm 50 perisporiums is greater than housing 30 is D2 away from the internal diameter of diaphragm 50 1 sides, but the perisporium 35 that is less than housing 30 is D1 near the internal diameter of diaphragm 50 1 sides.
The upper surface 56 of flange 52 and lower surface 31 adjacency of housing 30, the lower surface 57 of flange 52 is connected with the outer surface 33 of housing 30 perisporiums 35, and the upper surface 58 of diaphragm 51 and lower surface 42 adjacency of water outlet pressure plate 41.
Referring to Fig. 9 and Figure 10, when holder housing 30, first diaphragm 50 is installed on pedestal 40, then water outlet pressure plate 41 is fixed on diaphragm 50, finally housing 30 is installed on water outlet pressure plate 41, uses screw 60 through housing 30 and pedestal 40, housing 30 is fixed on pedestal 40.
In addition, the flange 43 of water outlet pressure plate 41 is pressed on the upper surface 58 of diaphragm 51 of diaphragm 50, and diaphragm 50, on upper surface 58, elastic strain occurs.In the footpath of diaphragm 50 upwards, flange 32, flange 34 and flange 43 lay respectively on the different circumference of diameter.Like this, by the different flange of axial height, footpath upwards the different flange of circle diameter diaphragm 50 is fixed between housing 30 and pedestal 40, and water is from the gap leakage between housing 30 and pedestal 40.
And, the perisporium outer surface 53 of diaphragm 50 and internal surface 36 adjacency of housing 30 perisporiums 35, the perisporium 35 that is greater than housing 30 due to the D outer diameter 3 of diaphragm 50 perisporiums is D2 away from the internal diameter of diaphragm 50 1 sides, but the perisporium 35 that is less than housing 30 is D1 near the internal diameter of diaphragm 50 1 sides, therefore the perisporium of diaphragm 50 in fact with perisporium 35 interference fit of housing 30, there is elastic strain in the flange 52 of diaphragm 50, the upper end of flange 52 is extruded and tilts to close diaphragm 50 axial directions, thereby contacts hermetically with housing 30.
The flange 54 of diaphragm 50 is positioned at the groove 44 of water outlet pressure plate 41, and spacing by groove 44 to flange 54 avoids diaphragm 50 moving in the radial direction.
Because diaphragm 50 is compressed by many flanges 32,34,43, when stabilized pressure pump work, even if diaphragm 50 needs high-frequency seism moving, also can upwards not wriggle in axial and footpath.And diaphragm 50 is made up of elastic material, coordinate with the perisporium of diaphragm 50 by the perisporium 35 of housing 30, diaphragm 50 can be by the gap filling between housing 30 and pedestal 40, and good seal performance, avoids water from the gap leakage between housing 30 and pedestal 40.
In addition, all flanges 32,34,43, all along the circumferential extension of housing 30 or water outlet pressure plate 41, can avoid diaphragm 50 upwards to wriggle in week, better by fixing diaphragm 50.
Stabilized pressure pump of the present utility model need to not arrange seal ring between water outlet pressure plate 41 and housing 30, when saving material simplified assembling process, can also avoid because of the sealability of the seal ring Seepage causing that declines.
Certainly, above-described embodiment be only the utility model preferred embodiment, when practical application, can have more change, for example, more flange is set on housing and water outlet pressure plate; Or the axis of flange and housing, water outlet pressure plate is obliquely installed; Or, between housing and pedestal, being fixedly connected with by other fixed blocks such as rivets, such change also can realize the purpose of this utility model.
The variation such as change, the change of flange setting position of diaphragm shape and making material finally it is emphasized that the utility model is not limited to above-mentioned mode of execution, as also should being included in the protection domain of the utility model claim.
