The utility model has the beneficial effects that：This to fall to spray in foam pump configuration, suck-back pipe sleeve is mounted in the input terminal of the pump housing,
Make product be easier to install, and nozzle side is provided with valve block made by flexible glue, foldable, foam can be effectively prevent
It overflows and remains, so that product is used and more clean, and tonifying Qi can be carried out to the negative pressure of vacuum in bottle, effectively solve to spray foam pump
To the Dependence Problem of bottle pliability.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the use state diagram of the utility model.
Specific implementation mode
Referring to Figures 1 and 2, one kind of the utility model, which is fallen, sprays foam pump, including storage bottle 1, the installation of 1 opening of storage bottle
There are the pump housing 2, the input terminal of the pump housing 2 to stretch into storage bottle 1, the input terminal of the pump housing 2 is set with suck-back pipe 3, has on the pump housing 2
The top of the recessed portion 4 opposite with the input port of the suck-back pipe 3, the pump housing 2 is equipped with annular groove 21, is set in annular groove 21
There are the elastomeric pad 18 for mending stomatal limiting value sealing with the pump housing, the output end of the pump housing 2 to be connected with Netcom 5, be connected in the Netcom 5
Head 6,6 end of head are equipped with by nozzle 7, should 7 side of nozzle be provided with valve block 8 made by flexible glue, foldable, the valve block
Reservoir 81 is formed in 8, is separately installed with large and small piston 9,10 in the pump housing 2, needle column 11 is provided in valve piston 10, it should
It is set with subpost 12 outside needle column 11, spring 13, the input terminal setting of the pump housing 2 are connected between the subpost 12 and valve piston 10
There is ball valve 14.This to fall to spray in foam pump configuration, suck-back pipe sleeve is mounted in the input terminal of the pump housing, and product is made to be easier to install, and
Nozzle side is provided with valve block made by flexible glue, foldable, foam overflow and residual can be effectively prevent, product is made to use
It more cleans, and tonifying Qi can be carried out to the negative pressure of vacuum in bottle, effectively solve spray foam pump and the dependence of bottle pliability is asked
Topic.
In the present embodiment, 6 end set of the head has annular groove 61, described to be inserted into the ring by 7 end edge of nozzle
It is formed in connected in star 61 and is fastened, made by being easier to dismount between nozzle and head.The pump housing 2 is connected through a screw thread lid 15 and is mounted on
On storage bottle 1.Pad valve 16 is provided between the large and small piston 9,10.The threaded connection lid 15 be set with can will it is described by
First 6 dust covers 17 surrounded.Foam pump fluid hole in travel position is in a sealed state with tonifying Qi hole, and is cased with dust cover
Prevent the downthrust in transportational process from causing to leak.Spray foam pump pulls out dust cover and is in inversion state when in use
(can be assemblied under normal circumstances in dedicated spraying equipment).First, it by nozzle by upward active force, is deformed inward and drives
Relevant built-in function part moves upwardly together, and opens infusion channel, while big piston moves up extrusion gas chamber with valve piston
With the gas and liquid in liquid chamber, gas together with liquid by Netcom formed foam, final foam liquid by head with press
The fluid hole of nozzle sprays.After being pressed into bottom, valve piston is moved down by acting force of the spring rebound, while valve piston drives big live
Plug, head are moved down by nozzle, and gas chamber opens the inside make-up gas in tonifying Qi hole because big Piston rebound generates negative pressure by padding valve,
Liquid chamber generates the logical bottom outlet of negative pressure because valve piston is sprung back and supplements liquid to liquid chamber, and generating negative pressure of vacuum after bottle internal cause ejection liquid can beat
Elastomeric pad is opened, the make-up gas into bottle, big piston, head, is sprung back to always top by nozzle at valve piston, and fluid hole is replied again
To sealing state.After recoiling to top, due to act on by nozzle power disappear, by nozzle with natural resiliency recovery shape, by nozzle from
Replied in invagination state, the inner space of reply then generate negative pressure will remain on returned by nozzle oral area foam liquid suck-back it is internal, from
And solve to press nozzle oral area liquid residue problem, even if the foam in infusion channel turns to liquid and also can be effectively trapped in by nozzle
Internal chamber.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the scope of protection of the utility model.
