Accompanying drawing explanation
Fig. 1 is embodiments of the invention structural representation.
Fig. 2 is the topside schematic diagram of embodiments of the invention.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the present invention is further described:
As shown in the figure, this Dewar bottle comprise have hold the body 1 of cavity 13, drive link 3, piston 4 that shower nozzle 2 that inside has the first cavity 21, inside have the second cavity 31; The top of body is provided with opening, and this opening part elasticity is provided with the valve block 5 of this opening of shutoff; Shower nozzle can be connected to body upper end along body axially reciprocating, drive link 3 is connected to the lower end of shower nozzle, specifically can adopt end drive link 3 being plugged on the first cavity or lower end drive link being butted up against shower nozzle that the second cavity is communicated with the first cavity, and the lower end of drive link is relative with valve block, the diameter of drive link is less than the diameter of valve block; Piston 4 slides and is arranged at the bottom of body, and the diameter of this piston is equal with the internal diameter of body; The bottom side of piston 4 is connected with elasticity at the bottom of the bottle of body 1 by Compress Spring 6.
The present invention in use, hold in cavity the liquid or emulsion or lotion of filling with and having under the contention effect of piston and Compress Spring, being in high pressure conditions, then press shower nozzle, make the end squeezing valve block of drive link, valve block and opening are departed from, diameter due to drive link is less than the diameter of valve block, thus space is formed between edge and the outer wall of drive link in opening, the liquid of high pressure or emulsion or lotion are from the ejection of this space thus enter in the second cavity, then enter the first cavity, finally spray from shower nozzle.Decontroling after shower nozzle, along offseting in the opening of valve block self-resetting and body, thus liquid or emulsion or lotion being continued shutoff holding in cavity.The present invention utilize Compress Spring by piston to being positioned at the liquid of body inside, emulsion, lotion provide power, only needs push valve block to make to hold and form passage between cavity and shower nozzle and liquid, emulsion, lotion can be sprayed, simple to operate; And simple and reliable for structure, be convenient to processing, productive costs is significantly reduced.
Particularly, the upper center of body 1 has the connection 11 of the column extended to body outside, and this connection 11 is embedded with a seal receptacle 7, and valve block 5 is placed in sealing seat 7; The top of sealing seat 7 is provided with seal bore 71, be provided with bottom it and the fluid hole 72 holding cavity connects, the lower end of valve block 5 is offseted with the bottom of Connection Block by a shutoff spring 51, the upper end of valve block offsets with the edge of seal bore under the elastic force effect of shutoff spring, thus is isolated from the outside by accommodation cavity; Namely seal bore 71 forms the opening of body.
The bottom of drive link 3 has the sealing 32 that radial direction extends to form; The upper end of seal receptacle is connected with a Sealed casing pipe 8, and the top of sealing sleeve pipe 8 is the directed cavity 81 that internal diameter is equal with drive link upper diameter, and its underpart is the annular seal space 82 of internal diameter and sealing equal diameters; Pilot bar is plugged in Sealed casing pipe slidably, and sealing is in annular seal space, thus makes the lower end of drive link relative with the valve block being positioned at seal receptacle.Wherein valve block 5 is valve ball.
The outer wall of connection 11 is provided with outside thread, and connection 11 is connected with the bottom of a connection pipe 9 by this outside thread; Thus Sealed casing pipe is in the middle part of connection pipe, the lower portion of shower nozzle is connected with Sealed casing pipe elasticity by a retracing spring 22; Thus make shower nozzle 2 can be connected to body 1 upper end along body axially reciprocating.Connection pipe 9 forms protection to its inner structure.
The arranged outside of sealing 32 has annular seal groove 33, is filled with the seal ring 34 with annular seal space contact internal walls in this annular seal groove.Drive link 3 partial sidewall be positioned at below sealing offers the introduction hole 35 be communicated with the second cavity.By arranging Sealed casing pipe, and the bottom of drive link being provided with sealing, making liquid, emulsion, lotion concentrate ejection in corresponding cavity, liquid, emulsion, lotion will be caused to reveal due to the free gap of drive link.
The bottom thread of body 1 is connected with bottom 12 and is formed at the bottom of bottle; Further elastic force is provided to Compress Spring thus guarantees that the present invention has when causing piston stroking upward by discharging to be threadedly connected at the bottom of bottle bottom body in liquid, emulsion, lotion part and spray power preferably.Body top is provided with crossette, and crossette place is covered with shower nozzle storage upper cover therebetween.
