Abstract
The invention relates to a balance wheel structure of a diaphragm pump. The balance wheel structure comprises a balance wheel body which comprises an annular side wall and a connecting block used for connecting diaphragms; an installation groove is formed in the inner side of the annular side wall, a supporting table is formed in the installation groove, a bearing is embedded into the installation groove, the two ends of the bearing in the axial direction are a first end and a second end, and the first end abuts against the supporting table; and the balance wheel structure further comprises a limiting component used for limiting the second end from leaving the installation groove in a sliding manner, and the limiting component is connected to the annular side wall. After the technical scheme is adopted, the limiting component limits the bearing to axially flee, and therefore noise generated by the diaphragm pump is reduced; and in addition, the balance wheel structure is quiet easy.
Description
Technical field
The invention belongs to membrane pump field, be specifically related to a kind of diaphragm pump balance structure.
Background technology
Along with the raising of people's living standard, water purifier has started to enter huge numbers of families, but the membrane pump on existing water purifier uses the problem easily producing noise after a period of time.This is caused due to existing barrier film pump structure and operation principle.Membrane pump mainly includes electric machine assembly and pump head, the pump head structure of existing a kind of membrane pump, and it is mainly by upper cover, O, valve block, valve seat, piston seat, delta-ring, small sucker, piston, screw, diaphragm, escapement, escapement seat etc..Having three boss on diaphragm, it forms three seal areas together with piston seat.A piston it is provided with in each seal area, piston is provided with screw hole, piston is connected with escapement by screw, escapement is embedded with bearing, bearing is embedded with eccentric, eccentric is connected with the motor output shaft of electric machine assembly, by the combined effect of eccentric and escapement, drives piston to do reciprocal class rectilinear motion and carries out pump water.
Existing a kind of diaphragm pump balance structure is as shown in Figure 3, it includes escapement body and bearing 20, escapement body includes annular sidewall 10 and the contiguous block 30 being connected on annular sidewall 10, this contiguous block 30 is connected with diaphragm, the inwall of annular sidewall 10 is mounting groove, being provided with support platform in mounting groove, bearing 20 is embedded in mounting groove and makes bearing 20 be resisted against on support platform.Easily there is bigger noise in current most of membrane pump after running a period of time, the escapement that its reason is in that on pump is connected by bearing with eccentric, and bearing can not be too tight with coordinating of escapement, otherwise can affect the life-span of bearing.Operationally, driven by motor eccentric rotates pump, thus driving piston to make reciprocal class rectilinear motion.Such bearing to bear double reaction plus axially and radially, operates for a long time, bearing can be made axial float occur, thus producing noise.
In consideration of it, the problems referred to above are carried out deep research by the present inventor, this case is then had to produce.
Summary of the invention
It is an object of the invention to provide a kind of it can be avoided that bearing play, alleviate the diaphragm pump balance structure of noise and simple structure.
In order to achieve the above object, the present invention adopts such technical scheme:
A kind of diaphragm pump balance structure, including escapement body, escapement body includes annular sidewall and in order to connect the contiguous block of diaphragm, the inner side of annular sidewall is mounting groove, is formed and supports platform, be embedded with bearing in mounting groove in mounting groove, bearing two ends vertically are set to the first end and the second end, first end is resisted against on support platform, also includes limiting described second end and slips away the limiting component of described mounting groove, and limiting component is connected on described annular sidewall.
As a kind of optimal way, described limiting component is screw, screw includes threaded portion and the nut portion being connected on threaded portion, nut portion is abutment end near one end of threaded portion, the other end is provided with the deep gouge in order to rotating screw cap portion, offering the axially arranged screw along described annular sidewall on described annular sidewall, screw is located in screw and makes described abutment end support and is located at described second end.
It is preferred that the outside of described annular sidewall is provided with to support a bracer of described abutment end, the corresponding described screw of a bracer is arranged.
It is preferred that the number of described screw is three, 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 peripheral of described screw, described second end exceeds the end face of described annular sidewall, described second end exceeds the height height equal to semi-circular boss of described annular sidewall, is provided with pad between described abutment end and described second end.
After adopting technical scheme, limiting bearing play vertically by limiting component, thus reducing the noise that membrane pump produces, and this swing wheel structure is very simple and easy.

Detailed description of the invention
In order to technical scheme is explained further, it is described in detail below in conjunction with accompanying drawing.
Referring to figs. 1 through Fig. 2, a kind of diaphragm pump balance structure, including escapement body, escapement body includes annular sidewall 10 and in order to connect the contiguous block 30 of diaphragm, the inner side of annular sidewall 10 is mounting groove, is formed and supports platform 80, be embedded with bearing 20 in mounting groove in mounting groove, bearing 20 two ends vertically are set to the first end and the second end, and the first end is resisted against on support platform 80.Present invention additionally comprises to limit described second end to slip away the limiting component of described mounting groove, limiting component is connected on described annular sidewall 10, limits bearing 20 play vertically by this limiting component.
As a kind of optimal way of the present invention, described limiting component is screw 40, and screw 40 includes threaded portion and the nut portion being connected on threaded portion, and nut portion is abutment end near one end of threaded portion, and the other end is provided with the deep gouge in order to rotating screw cap portion.Offering the axially arranged screw 50 along described annular sidewall 10 on described annular sidewall 10, screw 40 is located in screw 50 and makes described abutment end to support and is located at described second end.In order to better, limit bearing 20 play vertically, reducing the noise of membrane pump, as the optimal way of the present invention, 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 peripheral 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, described second end exceeds the height height equal to semi-circular boss 70 of described annular sidewall 10, being provided with pad (not shown) between described abutment end and described second end, pad is set in outside screw 40.So after screw 40 is tightened, bearing 20 can be compressed by pad, it is prevented that bearing 20 is axially movable.
As a kind of optimal way, in an embodiment, the outside of described annular sidewall 10 is provided with to support a bracer 60 of described abutment end, and a corresponding described screw 40 of bracer 60 is arranged, end face common support screw 40 by a bracer 60 with annular sidewall 10, it is ensured that the steady connection of screw 40.
