Description
Technical field
The utility model relates to sprayer, particularly relates to the straight top type safety valve of hand-held atomizer.
Background technology
For the personal safety that prevents the user comes to harm, safety device generally is set on sprayer, guarantee that to greatest extent sprayer is operated in the safe range, nonoverload, do not break.Existing hand-held atomizer is installed safety valve mostly on the kettle body, the kettle body adopts the blowing of PE (polyethylene) material to form, this simple in structure, convenient formation, but for some kettle body in order to guarantee good looking appearance, be not suitable on the kettle body, safety valve being installed, simultaneously for small-sized kettle body, people's appearance requirement is higher, often adopt PET (PET) material, the kettle surface fineness that the PET material is made is good, and product is transparent, lovely luster, the intensity height, but the extensibility of PET material and plasticity do not have the PE material good, except Hu Kou design has the screw thread, again can't be on the kettle body moulding be used for fixing the screw thread of safety valve, therefore this class sprayer does not often have safety valve, uses dangerous.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, provide a kind of can be on the liquid storage kettle of making by the PET material fixing safety valve, thereby reach purpose safe in utilization, and the hand-held atomizer straight top type safety valve of simple structure, compact conformation.
The technical scheme of the utility model hand-held atomizer straight top type safety valve is: hand-held atomizer comprises kettle body and pot lid, is provided with suction hose and pressure measuring cylinder in the kettle body, and piston component is housed in the pressure measuring cylinder, and piston component connects inflates handle; Pot lid is divided into bottom and top through baffle plate, be shaped on water channel on the baffle plate, water channel connects suction hose, the bottom is threaded with the oral area of kettle body, one side on pot lid top is equipped with shower nozzle, shower nozzle is communicated with water channel, and the opposite side on top is provided with handle, trip gear is housed in the handle is connected with the switch of shower nozzle, block is equipped with at the pot lid top, it is characterized in that being shaped on movable span in the described block, the pot lid sidewall is shaped on venthole, is shaped on relief hole in the baffle plate, be shaped on open tubular column on the baffle plate, open tubular column communicates with relief hole and venthole, and spool is housed in the open tubular column, and following of spool is equipped with sealing ring, the sealing ring sealing that contacts with relief hole, spool is equipped with spring outward, and two of spring is withstood baffle plate and block respectively, and the higher authorities of spool pass movable span.
Hand-held atomizer straight top type safety valve of the present utility model, avoid conventional art and generally adopt on the kettle body the fixedly thinking of safety valve, and safety valve is fixed on the pot lid, on baffle plate, be shaped on open tubular column, relief valve assembly is installed in the open tubular column, utilize directly compression spring of block, simple in structure, compact.During work, twitch earlier and inflate handle, increase the pressure in the kettle body, after hand was pressed trip gear, the switch of shower nozzle was opened, and the pressure differential of kettle inside and outside forces liquid to spray from shower nozzle through suction hose, water channel; Behind the spring pressure of pressure in the liquid storage kettle body greater than safety valve, spring is compressed, move on the spool, at this moment, kettle body intracavity, relief hole and venthole form passage, gases at high pressure from then on passage release to the external world, thereby reduce the pressure in the kettle body, make the pressure in the kettle body remain at safe condition.

Fig. 2 is the schematic perspective view of the utility model hand-held atomizer straight top type safety valve.
The specific embodiment
The utility model discloses a kind of hand-held atomizer straight top type safety valve, as shown in Figure 1 and Figure 2, hand-held atomizer comprises kettle body 1 and pot lid 2, is provided with suction hose 3 and pressure measuring cylinder 4 in the kettle body, and piston component 5 is housed in the pressure measuring cylinder, and piston component connects inflates handle 6; Pot lid 2 is divided into bottom and top through baffle plate 21, be shaped on water channel on the baffle plate 21, water channel connects suction hose 3, the bottom is threaded with the oral area of kettle body 1, one side on pot lid top is equipped with shower nozzle 7, shower nozzle 7 is communicated with water channel, and the opposite side on top is provided with handle 8, trip gear 9 is housed in the handle is connected with the switch of shower nozzle 7, block 10 is equipped with at pot lid 2 tops, it is characterized in that being shaped on movable span 101 in the described block 10, pot lid 2 sidewalls are shaped on venthole 28, are shaped on relief hole 26 in the baffle plate 21, be shaped on open tubular column 27 on the baffle plate, open tubular column 27 communicates with relief hole 26 and venthole 28, and spool 15 is housed in the open tubular column 27, and following of spool is equipped with sealing ring 16, the sealing ring sealing that contacts with relief hole 26, the spool 15 outer springs 17 that are equipped with, two of spring is withstood baffle plate 21 and block 10 respectively, and the higher authorities of spool 15 pass movable span 101.This programme is avoided conventional art and is generally adopted on the kettle body the fixedly thinking of safety valve, and safety valve is fixed on the pot lid 2, on baffle plate 21, being shaped on open tubular column 27, relief valve assembly is installed in the open tubular column 27, utilize directly compression spring 17 of block 10, simple in structure, compact.During work, twitch earlier and inflate handle 6, increase the pressure in the kettle body 1, after hand press trip gear 9, the switch of shower nozzle 7 was opened, and the pressure differential of kettle inside and outside forces liquid to spray from shower nozzle 7 through suction hose 3, water channel; Behind spring 17 pressure of the pressure in the liquid storage kettle body greater than safety valve, spring is compressed, move on the spool 15, at this moment, kettle body intracavity 11, relief hole 26 and venthole 28 form passage, gases at high pressure from then on passage release to the external world, thereby reduce the pressure in the kettle body, make the pressure in the kettle body remain at safe condition.
