Description
Technical field
The utility model relates to for water purifier suction booster technical field, particularly relates to a kind of suction booster diaphragm fixed structure.
Background technique
Adopting Reverse Osmosis Technology to carry out in the water purifier of purification of water quality, suction booster sucks former water from water intake in the course of the work, and the pressurization by suction booster increases to certain pressure by water and discharges.The diaphragm of suction booster and on piston, should play intact water buffer action, ensure again the smooth and easy of transmission, can make the motor driving shaft in the pump housing drive driving mechanism to produce axially reciprocating, and by repeatedly upwards pushing the piston diaphragm in the low pressure valve on piston valve base, water is clamp-oned to hyperbaric chamber from low pressure chamber, with certain pressure, export.
Referring to Fig. 1 and Fig. 2, diaphragm 110 is made by elastic plastic material conventionally, main body is triangular in shape, the through hole 121 of piston 120 equates with through hole 111 apertures of diaphragm 110, piston 120 is in diaphragm 110 upper surface location, through hole 121,111 alignment each other, more fixing with the driving mechanism 140 of below by screw 130.
But, in manufacture control process, easily there is screw and twist situation not in place or not tight, thereby cause this place's seal failure, cause and leak.In addition, adopt fastened by screw mode, operation is relatively inconvenient, and efficiency is lower.
Summary of the invention
For solving the deficiency existing in prior art, technical problem to be solved in the utility model is to provide a kind of leakproofness and suction booster simple in structure diaphragm fixed structure of strengthening.
To achieve these goals, the utility model is to realize by the following technical solutions:
A suction booster diaphragm fixed structure, comprises piston, diaphragm and driving mechanism, and described piston comprises head and bar portion, the outstanding head central authorities that are formed at of bar portion; Described diaphragm has sealed department, is provided with the fluting of corresponding head moulding and the through hole of connection thereof in described sealed department; Described driving mechanism has the hole of the corresponding bar portion moulding of the seal groove of corresponding sealed department moulding and connection thereof.
Preferably, described head is in the form of annular discs, and described bar portion is cylindric, and described sealed department external frame is cylindric.
Preferably, described piston is screw-like, and cross section is T-shape.
The beneficial effect of technical solutions of the utility model is:
A kind of suction booster diaphragm fixed structure of the present utility model, because described piston comprises head and bar portion, the outstanding head central authorities that are formed at of bar portion; Described diaphragm has sealed department, is provided with the fluting of corresponding head moulding and the through hole of connection thereof in described sealed department; Described driving mechanism has the hole of the corresponding bar portion moulding of the seal groove of corresponding sealed department moulding and connection thereof.So not only structure is simpler, and sealing effect is better.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of diaphragm fixed structure for the suction booster of prior art.
Fig. 2 is that the structure of Fig. 1 is integrated schematic diagram.
Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of diaphragm fixed structure for a kind of suction booster of the present utility model.
Fig. 4 is that the structure of Fig. 3 is integrated schematic diagram.
Embodiment
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Embodiment:
As shown in Figure 3 and Figure 4, a kind of suction booster diaphragm fixed structure of the present embodiment, comprises piston 120, diaphragm 110 and driving mechanism 140.
The piston 120 that integral body is screw-like comprises head 121 and bar portion 122, the outstanding general middle position that is formed at head 121 lower surfaces of bar portion 122.Head 121 is whole in the form of annular discs, and bar portion 122 integral body are cylindric.From the whole-cutaway view of piston 120, its cross section is T-shape.
Diaphragm 110 main bodys are equilateral triangle, and the lower surface of diaphragm 110 is evenly distributed with three regions that interfix and coordinate with driving mechanism 140, the outstanding cylindrical sealed department 111 of whole external frame that is formed with in substantial middle position in this each region.The interior general middle position near upside of sealed department 111 is provided with the fluting 112 of head 121 moulding of corresponding piston 120, for accommodating head 121.The general middle position of 112 downsides of slotting is provided with the through hole 113 being communicated with it, for wearing bar portion 122.
Driving mechanism 140 is provided with seal groove 141 and hole 142 from top to bottom, and seal groove 141 and hole 142 are interconnected.Sealed department 111 moulding of the corresponding diaphragm 110 of seal groove 141, bar portion 122 moulding of the corresponding piston 120 in hole 142.
A kind of suction booster diaphragm fixed structure of the present embodiment, while being fixed operation, the sealed department 111 of diaphragm 110 is placed in the seal groove 141 of driving mechanism 140, and sealed department 111 is mutually closely sealed with seal groove 141.Piston 120 wears diaphragm 110 and driving mechanism 140 downwards successively, and the head 121 of piston 120 is placed in the fluting 112 of diaphragm 110; After the through hole 113 of the bar portion 122 break-through diaphragms 110 of piston 120, bottom is placed in the hole 142 of driving mechanism 140.Finally, adopt the mode of ultrasonic welding by piston 120, diaphragm 110 to be effectively connected with driving mechanism 140.
Above specific embodiment of the utility model is described.It will be appreciated that, the utility model is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present utility model.
