Abstract
The utility model relates to an electric pump for a sprayer, particularly a miniature electrical appliance which is matched with a sprayer to use. The utility model can spray various water and oil liquid such as the biocidal agent, etc. The utility model is inlaid with a miniature DC motor directly. The utility model has the advantages of simple and compact structure, light weight, small size, and strong practicability. The utility model is suitable for plant protection for the agriculture, sanitation and antiepidemic prevention, disinfection, etc.
Description
The utility model sprayer electric pump relates to a kind of compact electric apparatus that cooperates sprayer to use, and it belongs to a kind of agricultural instrument.
At present, knapsack hand sprayer needs the people to carry, and that does not stop presses hand lever, just can be with the ejection of the soup in the sprayer, and this sprayer easily makes the people have a pain in the back, and usually presses not Shang gas or annotate and fill in mouth and emit water, makes soup glue body, easily causes pesticide poisoning etc.; More existing power sprayes free the people from fatigue, but since integral production, the cost height, and its volume is big, except that centrifugal pump, also is furnished with accessories such as atomizer, and when the user uses, need discarded original sprayer, its market is very restricted.
The purpose of this utility model is exactly in order to solve the shortcoming of above-mentioned prior art, and on the basis of discarded existing manual sprayer, directly installs the utility model sprayer electric pump additional on manual sprayer, makes manual sprayer become power spraye.The utility model is simple in structure, and is easy for installation, in light weight, uses light.
Technical solution of the present utility model is as follows:
The utility model sprayer electric pump, form by the pump housing (1) and DC micromotor (2), it is characterized in that: be provided with a circle collar (5) in the pump housing (1) rear end, the preceding end housing build-in of it and DC micromotor (2) is an one, and the output shaft of DC micromotor (2) centre bore direct and impeller (6) is fixed with one, be connected with pump cover (7) at the pump housing (1) front end, the middle part, outer end of pump cover (7) is connected with the water inlet pipe perpendicular with its center line (3), the water inlet of water inlet pipe (3) is connected with the soft pipe connection of sprayer by internal thread, the outlet of water inlet pipe (3) is communicated with the impeller cavity (9) of the pump housing (1) by pump cover (7) centre bore (10), vertical with its center line and to be provided with delivery port (4) delivery port with water inlet pipe (3) position in the opposite direction be tapered anemostat in the pump housing (1) inwall tangential direction, this delivery port (4) is connected with the sprayer valve by external thread structure.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a pump housing interior schematic diagram of the present utility model;
Fig. 3 is a generalized section of the present utility model.
As shown in Figure 1, 2, 3, when the back sprayer, open the sprayer valve after, the soup in the sprayer flows in the pump housing of the present utility model (1) naturally, DC micromotor this moment (2) is connected power supply, its output shaft impeller (8) running; The water inlet pipe of soup electric pump (3) enters impeller cavity (9) by pump cover (7) centre bore (10), impeller (6) is under the high speed of direct current generator (2) drives, make soup along with impeller does to force circumnutation in impeller cavity, at this moment having partly, soup produces the spraying of high pressure liquid stream through the valve and the various suitable agriculture requirements of ejection such as spray boom, shower nozzle of sprayer along conic diffuse (the existing mouth of a river (the 4)) output of pump housing inwall tangential direction device.
