Abstract

The utility model relates to an ultra-low spraying pump, comprising a nozzle 1, a pressing head 2, a piston 3, a pump cover 4, a valve rod 8, a pump body 9 and a spring 10; the upper part of the valve rod is inserted in the piston; the lower part of the valve rod is inserted in the pump body; the pressing head is sleeved on the piston; the nozzle is arranged at one side of the pressing head; the pump cover is arranged below the pressing head and is sleeved on the pump body; the spring is arranged in the internal bottom of the pump body. The utility model belongs to no-ball pump; the valve rod in the pump directly acts on the upper piston and the pump body. The utility model has the advantages of most simple structure, strong explosive force, reducing the movable stroke, short length of the whole pump body, directly feeling hidden on the position of a bottle after using packages such as astringents, etc., beautifying the entrails of the finished products, saving the assembly cost and reducing the production cost owning to few parts.

Description

Super short atomizing pump

Technical field:

The utility model relates to a kind of pump.Be specifically related to a kind of super short atomizing pump.Belong to the spray apparatus technical field.

Background technology:

Common atomizing pump is generally formed by pressing head, nozzle, connection gland, the pump housing, upper and lower piston, valve rod, valve seat, spring, ball and suction pipe etc.During spraying, depress and press head, valve rod is opened thereupon, and liquid is pressed onto the nozzle zone by piston inner hole in the pump housing, and liquid is ejection fast under the effect of pump internal pressure.Owing in this atomizing pump pump ball is arranged, act on piston and ball by valve rod in the pump, again by the ball effect and the pump housing, complex structure, a little less than the explosive force, movable stroke is long, and the pump housing is long.In addition because the entire pump body length is long, packing such as toner is used after, the pump bottom is at the bottleneck position, the finished product internal organ are not attractive in appearance.And because part is many, assembling cost height, production cost is also high.

Summary of the invention:

It is a kind of simple in structure that the purpose of this utility model is to provide, and explosive force is strong, pump housing length is short, assemble cost and the low super short atomizing pump of production cost.

Technology contents of the present utility model is: a kind of super short atomizing pump, comprise nozzle, press head, piston, pump cover, valve rod, the pump housing and spring, valve rod top is inserted in the piston, the bottom is inserted in the pump housing, press headgear and place on the piston, nozzle unit is in pressing first side, and pump cover places presses the head below, be placed on the pump housing, spring places pump housing inner bottom part.

Because the utility model belongs to no ball-type pump, directly act on the upper piston and the pump housing by valve rod in the pump, structure is the simplest, and explosive force is strong.Because directly act on, generation activity stroke shortens, the entire pump body length is very short, packing such as toner is used after, its direct sensation is just hided at the position of bottleneck, has beautified the internal organ of finished product.And, saved the assembling cost greatly because part is few, and also reduced production cost, be that a kind of invention in the spraying industry improves.

Description of drawings:

Fig. 1 is an example structure schematic diagram of the present utility model.

The specific embodiment:

As Fig. 1, the utility model is a kind of super short atomizing pump, by nozzle 1, press 2, piston 3, pump cover 4, O RunddichtringO 5, electrochemical aluminium gland 6, pad 7, valve rod 8, the pump housing 9, spring 10 and suction pipe 11 form.Valve rod 8 tops are inserted in the piston 3, the bottom is inserted in the pump housing 9, press 2 and be placed on piston 3 tops, nozzle 1 is installed on presses 2 one side, pump cover 4 places presses 2 below, be placed on the pump housing 9, set O RunddichtringO 5 between pump cover 4 and piston 3 outside wall surface, electrification aluminium gland 6 be sleeved on pump cover 4 tops and around, be nested with pad 7 on the pump housing 9, pad 7 places pump cover 4 lower surfaces, and spring 10 places the pump housing 9 inner bottom parts, its top is placed on valve rod 8 bottoms, and suction pipe 11 inserts in the endoporus of pump housing bottom from the pump housing 9 bottoms.
