Description

Hand-held atomizer laterally pushed type safety valve

Technical field

The utility model relates to sprayer, particularly relates to hand-held atomizer laterally pushed type safety valve.

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, be applicable to the kettle body that volume is bigger, but for small-sized kettle body, people are higher for the appearance requirement of kettle body, and the kettle surface fineness that adopts PET (PET) material to make is good, product is transparent, bright in colour, the intensity height, therefore small-sized kettle body all adopts the PET material to make, but the extensibility of PET material and plasticity do not have the PE material good, except the Hu Kou design has the screw thread, can't on the kettle body, moulding be used for fixing the screw thread of safety valve again, so adopt this class sprayer of PET material often not have safety valve, use dangerous.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of and can on the liquid storage kettle of being made by the PET material mounting structure be set, being used for fixing safety valve, thereby reaching the hand-held atomizer laterally pushed type safety valve of purpose safe in utilization.

The technical scheme of the utility model hand-held atomizer laterally pushed type safety valve is: hand-held atomizer comprises liquid storage kettle body, the oral area of liquid storage kettle body is installed pot lid, block is equipped with at the pot lid top, be provided with suction hose and pressure measuring cylinder in the liquid storage kettle body, piston component is housed in the pressure measuring cylinder, and piston component connects inflates handle; Be shaped on water channel in the pot lid, one side of pot lid is equipped with shower nozzle, shower nozzle communicates with suction hose through water channel, the opposite side of pot lid is shaped on handle, handle is connected with the switch of shower nozzle through trip gear, it is characterized in that being shaped on pressure release passage in the described pot lid, pressure release passage communicates with the inner chamber of liquid storage kettle body, the pot lid outer wall is shaped on valve seat orifice, and valve seat orifice communicates with pressure release passage, the interior fixedly safety valve of valve seat orifice, safety valve comprises valve body, mounting spring in the valve body is equipped with spool in the spring, spool passes valve body and connects bonnet.

Hand-held atomizer laterally pushed 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, pot lid is still made by the PE material, because the PE material has good extensibility and plasticity, therefore when the injection moulding pot lid, can directly in pot lid, be shaped on pressure release passage and the valve seat orifice that communicates, safety valve is installed in the valve seat orifice, during use, is twitched earlier and inflate handle, increase the pressure in the liquid storage 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 through suction hose, water channel sprays from shower nozzle; Behind the spring pressure of pressure in the liquid storage kettle body greater than safety valve, spring is compressed, at this moment, liquid storage kettle body intracavity, pressure release passage and valve seat orifice form passage, gases at high pressure from then on passage release to the external world, thereby reduce the pressure in the liquid storage kettle body, make the pressure in the kettle body remain at safe condition.

Hand-held atomizer laterally pushed type safety valve of the present utility model, its described installing hole is shaped on internal thread, and the valve body of safety valve is shaped on external screw thread, and external screw thread matches with internal thread, also can adopt other connected mode, connects as buckle.The transition position of its described pressure release passage and valve seat orifice is shaped on the taper valve port, and one of spool is equipped with sealing ring, and sealing ring contacts with the taper valve port, and the taper valve port helps guiding and good sealing effect.
