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 the problem of noise 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, the pump head structure of existing a kind of diaphragm pump, and it is primarily of upper cover, O shape circle, valve block, valve seat, piston seat, delta-ring, small sucker, piston, screw, diaphragm, escapement, escapement seat etc.Diaphragm has three boss, and it forms three seal areas together with piston seat.A piston is provided with in each seal area, piston is provided with screw hole, piston is connected with escapement by screw, bearing is embedded with in escapement, eccentric wheel is embedded with in bearing, eccentric wheel is connected with the motor output shaft of electric machine assembly, by the acting in conjunction of eccentric wheel and escapement, drives piston to do reciprocal class straight line motion and carries out pump water.
Existing a kind of diaphragm pump balance structure as shown in Figure 3, it comprises escapement body and bearing 20, the contiguous block 30 that escapement body comprises annular sidewall 10 and is connected on annular sidewall 10, this contiguous block 30 is connected with diaphragm, the inwall of annular sidewall 10 is mounting groove, in mounting groove, be provided with support platform, bearing 20 to be embedded in mounting groove and bearing 20 is resisted against on support platform.Easily there is larger noise after running a period of time in current most of diaphragm pump, its reason is that the escapement on pump is connected by bearing with eccentric wheel, and bearing and coordinating of escapement can not be too tight, otherwise can affect the life-span of bearing.Operationally, driven by motor eccentric wheel rotates pump, thus drives piston to make reciprocal class straight line motion.Such bearing will bear axially and radial double reaction plus, operates for a long time, bearing can be made to occur axial float, thus produces noise.
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 to provide a kind of can avoid bearing play, alleviate noise and the diaphragm pump balance structure of simple structure.
In order to achieve the above object, the utility model adopts such technological scheme:

As a kind of optimal way, described limit position part is screw, screw comprises screw section and is connected to the nut portion on screw section, nut portion is abutment end near one end of screw section, the other end is provided with the deep gouge in order to rotating screw cap portion, described annular sidewall offers the screw that the axis along described annular sidewall is arranged, screw to be located in screw and to make described abutment end to being located at described second end.
Preferably, the outside of described annular sidewall is provided with the support block supporting described abutment end, and the corresponding described screw of support block is arranged.
Preferably, the number of described screw is three, and equidistant ring is located in described annular sidewall, and described screw correspondence is set to three.
Preferably, described annular sidewall is provided with semi-circular boss near one end of described screw, semi-circular boss is arranged along the periphery of described screw, described second end exceeds the end face of described annular sidewall, the height that described second end exceeds described annular sidewall equals the height of semi-circular boss, is provided with pad between described abutment end and described second end.
After adopting the technical solution of the utility model, by limit position part restriction bearing play vertically, thus reduce the noise of diaphragm pump generation, and this swing wheel structure is very simple and easy.

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. 2, a kind of diaphragm pump balance structure, comprise escapement body, escapement body comprises annular sidewall 10 and the contiguous block 30 in order to be connected diaphragm, the inner side of annular sidewall 10 is mounting groove, forms support platform 80, be embedded with bearing 20 in mounting groove in mounting groove, bearing 20 two ends are vertically set to first end and the second end respectively, and first end is resisted against on support platform 80.The utility model also comprises limiting described second end and to slip away the limit position part of described mounting groove, and limit position part is connected on described annular sidewall 10, limits bearing 20 play vertically by this limit position part.
As a kind of optimal way of the present utility model, described limit position part is screw 40, and screw 40 comprises screw section and is connected to the nut portion on screw section, and nut portion is abutment end near one end of screw section, and the other end is provided with the deep gouge in order to rotating screw cap portion.Described annular sidewall 10 offers the screw 50 that the axis along described annular sidewall 10 is arranged, and screw 40 to be located in screw 50 and to make described abutment end to being located at described second end.In order to better, restriction bearing 20 play vertically, reduces the noise of diaphragm pump, as optimal way of the present utility model, described annular sidewall 10 is provided with semi-circular boss 70 near one end of described screw 40, and semi-circular boss 70 is arranged along the periphery of described screw 50.After bearing 20 is assembled to mounting groove, second end of bearing 20 exceeds the end face of described annular sidewall 10, such as exceed 0.05-0.1mm, the height that described second end exceeds described annular sidewall 10 equals the height of semi-circular boss 70, be provided with pad (not shown) between described abutment end and described second end, pad is set in outside screw 40.Like this after screw 40 is tightened, bearing 20 can compress by pad, prevents bearing 20 from moving vertically.
