Abstract

The utility model relates to an electric diaphragm pump which is composed of a motor and a diaphragm pump assembly connected with the motor, wherein the diaphragm pump is installed on an eccentric base of a motor shaft, and the external wall of the eccentric base is connected with a bearing of which the outside is connected with a bearing base. Three milling and rubbing slice fixed columns are arranged on the bearing base, and fixed holes provided with sealing rings on the brims are arranged in the fixed columns. The bearing base is arranged in a large diaphragm base in which three circular holes are arranged, and the three fixed columns of the bearing seat penetrate through the three circular holes. A large diaphragm provided with a connecting hole is arranged in front of the large diaphragm base, and a small milling and rubbing circular slice is arranged in the large diaphragm. Three water absorbing tables and a small diaphragm hole are arranged in a small diaphragm base arranged in front of the large diaphragm. Water absorbing holes are arranged on the water absorbing tables, and water absorbing diaphragms are arranged in the water absorbing tables. A small diaphragm is arranged in the small diaphragm hole, and a sealing ring is arranged between the small diaphragm hole and the small diaphragm. The end cap of the motor and the large diaphragm base are connected with a pump body which is provided with a water inlet and a water outlet.

Description

Electric diaphragm pump

Technical field

The utility model relates to diaphragm pump, particularly relates to electric diaphragm pump, mainly is applicable on sprayer and the washing apparatus.

Background technique

The apparatus of often using in crops prevention and elimination of disease and pests, health and epidemic prevention or article-cleaning (as car etc.) is sprayer or washing apparatus, sprayer has manually and motor-driven two kinds, power driven sprayer now is generally power spraye, and its main structure is compositions such as liquid medicinal case, storage battery, motor, sprayer pump and sprinkler part.Existing power spraye pump is to adopt plunger pump (or claiming reciprocating pump) as power, it is big to exist volume mostly, and weight is too heavy, and especially knapsack sprayer has increased the load of human body, and shortcoming such as damage has easily influenced working efficiency again.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of volume dexterity to be provided, and is in light weight, the electric diaphragm pump of long service life.

The technological scheme of the utility model electric diaphragm pump is: be made up of with the diaphragm pump assembly that is connected motor motor, it is characterized in that described diaphragm pump is mounted in the eccentric mounting on the motor shaft, eccentric mounting outer wall connection bearing, the outside coupling shaft bearing of bearing, be shaped on three mills on the bearing support and rub the sheet fixing column with the hands, be shaped on fixed hole in the fixing column, there is seal ring at the fixed hole edge, bearing support is installed in the big diaphragm seat, be shaped on three circular holes in the big diaphragm seat, three fixing columns of bearing support pass circular hole, before big diaphragm seat big diaphragm are installed, big diaphragm is shaped on attachment hole, in the big diaphragm mill is installed and is rubbed with the hands sequin, before the big diaphragm membranelle bar is arranged, be shaped on three suction platforms and a membranelle film perforation in the membranelle bar, be shaped on the suction hole on the suction platform, the suction diaphragm is installed in the suction platform, in the membranelle film perforation Small diaphragm-piece is installed, between has seal ring, the end cap of motor is connected with the pump housing with big diaphragm seat, and the pump housing is shaped on water intake and water outlet.

When the utility model is worked when electric motor starting, eccentric wheel that motor shaft drives and bearing produce rotation, make and be connected the outer continuous offset movement of bearing support of bearing, make the big diaphragm and the mill stranding sequin that are installed on the bearing support fixing column follow offset movement like this, the result of mill stranding sequin offset movement constantly acts on the suction Small diaphragm-piece in the membranelle bar, and the pressure of suction Small diaphragm-piece constantly changes the water intake and the water outlet that make the pump housing and reaches suction and draining.The present technique structure is except that the weight of motor, and pump body majority is made by plastics and rubber material, and volume is little, and is in light weight, not fragile, changes very convenient again.
