Description
Technical field
The utility model belongs to water pump field, is specifically related to a kind of diaphragm of diaphragm pump.
Background technique
Along with the raising of people's living standard, water purifier has started to enter huge numbers of families, but the diaphragm pump on existing water purifier easily produces leakage water problem after using a period of time.This caused due to existing barrier film pump structure and working principle.Diaphragm pump mainly comprises electric machine assembly and pump head, as shown in Figure 5, it is primarily of upper cover 1, O shape circle 2, valve block 3, valve seat 4, piston seat 5, delta-ring 7, small sucker 8, piston 9, screw 10, diaphragm body 11, escapement 12, escapement seat 13 etc. for the pump head structure of existing a kind of diaphragm pump.Diaphragm body 11 has three boss, and it forms three seal areas together with piston seat 5.A piston 9 is provided with in each seal area, piston 9 is provided with screw hole, piston 9 is connected with escapement 12 by screw 10, bearing (not shown) is embedded with in escapement 12, eccentric wheel (not shown) is embedded with in bearing, eccentric wheel is connected with the motor output shaft of electric machine assembly (not shown), by the acting in conjunction of eccentric wheel and escapement 12, drives piston 9 to do reciprocal class straight line motion and carries out pump water.In order to anti-sealing is from the screw hole of piston 9 to external leakage, diaphragm body 11 is provided with the hollow frustum of a platform and protrusion, and when tightening screw, the structure on piston 9 seals therewith; In order to anti-sealing leaks between upper cover 1 and escapement seat 13, diaphragm body 11 has protruded two sealing folding faces in outside, is formed seal with piston seat 5, and upper cover 1 passes through delta-ring 7 and diaphragm body 11 and piston seat 5 and formed and seal, so in principle, water would not spill outside the pump housing.But owing in the pump housing being high pressure hydroecium, piston 9 bears thrust and the pulling force of high frequency periodic, of long duration, due to the fatigue of sealing material, the impact of the stress deformation of each parts etc., will produce the problem of poor sealing, thus generation is leaked.
Given this, the present inventor carries out deep research to the problems referred to above, then has this case to produce.
Model utility content
The purpose of this utility model is the diaphragm of diaphragm pump providing a kind of leak preventing effect better.
In order to achieve the above object, the utility model adopts such technological scheme:
A kind of diaphragm of diaphragm pump, comprise diaphragm body and be connected to the piston on diaphragm body, diaphragm body is provided with the first collar flange coordinated with piston seat, described piston is shaped in described diaphragm body near the side of described piston seat, and the opposite side of described diaphragm body is connected with escapement by contiguous block.
As a kind of optimal way, described contiguous block comprises the annular flange extended towards described escapement and the fixture block being arranged on annular flange outer wall, described escapement is provided with the through hole mated with annular flange and the annular brace step being arranged on through-hole wall, and fixture block is fastened on annular brace step.
As further improvement of the utility model, the week of described diaphragm body is along being provided with the ring-shaped platform extended towards the outside of described diaphragm body, the week of ring-shaped platform is along being provided with annular boss, annular boss and described first collar flange are arranged in the same way, form annular groove between the inwall of annular boss and the outer wall of the first collar flange.
After adopting the technical solution of the utility model, due to piston and this body by integral forming of diaphragm, without the need to offering screw hole on piston, completely avoid the problem that in prior art, water is revealed from screw hole, after adopting diaphragm body of the present utility model, the assembling of pump head is convenient, and the leak preventing effect of whole pump head more simultaneously.
As further improvement of the utility model, by the ring-shaped platform that extends in the arranged outside of diaphragm body with arrange annular boss on ring-shaped platform, after pump head assembling, even if there is water to reveal from the first collar flange, by the barrier effect of annular groove and annular boss, the leak preventing effect of whole pump head can be strengthened further.

Embodiment
In order to explain the technical solution of the utility model further, be described in detail below in conjunction with accompanying drawing.
Referring to figs. 1 through Fig. 4, a kind of diaphragm of diaphragm pump, the piston 9 comprising diaphragm body 11 and be connected on diaphragm body 11, diaphragm body 11 is provided with the first collar flange 111 coordinated with piston seat 5, the second collar flange 112 is also provided with in the inner side of the first collar flange 111, first collar flange 111 and the second collar flange 112 coordinate with piston seat 5 latter two seal folding face, these are existing in the prior art introduces, and no longer describes in detail here.Piston 9 described in the utility model is shaped in the side of described diaphragm body 11 near described piston seat 5, and the opposite side of described diaphragm body 11 is connected with escapement 12 by contiguous block 6.
As a kind of optimal way, described contiguous block 6 comprises the annular flange 61 extended towards described escapement 12 and the fixture block 62 being arranged on annular flange 61 outer wall, described escapement 12 is provided with the through hole 121 mated with annular flange 61 and the annular brace step 122 being arranged on through hole 121 inwall, fixture block 62 is fastened on annular brace step 122, also be squeezed into through hole 121 from through hole 121 near one end of diaphragm body 11 by fixture block 62, and make fixture block 62 be stuck on annular brace step 122 by the mode of left-hand thread, the swing of escapement 12 like this can drive piston 9 to do class straight reciprocating motion.
As further improvement of the utility model, the week of described diaphragm body 11 is along being provided with the ring-shaped platform 113 extended towards the outside of described diaphragm body 11, the week of ring-shaped platform 113 is along being provided with annular boss 114, annular boss 114 extends towards piston seat 5 direction, also namely annular boss 114 is located at the periphery of described first collar flange 111, forms annular groove 115 between the inwall of annular boss 114 and the outer wall of the first collar flange 111.The sealability of seal area in diaphragm pump is further enhancing after annular boss 114 and annular groove 115 coordinate with piston seat 5.
Product form of the present utility model is not limited to this case diagram and embodiment, and anyone carries out suitable change or the modification of similar thinking to it, all should be considered as not departing from patent category of the present utility model.
