Description
Technical field
The present invention relates to a kind of hand-held atomizer, particularly relate to the built-in safety valve of hand-held atomizer.
Background technology
Hand-held atomizer is a kind of miniaturised nebuliser, mainly is to sprayings such as pot flowers, sapling, the usefulness of watering.At present, safety (valve) device is set all on such sprayer, prevents that user's personal safety from coming to harm, guarantee that to greatest extent sprayer is operated in the safe range, nonoverload, do not break.But existing hand-held atomizer safety valve is installed on the pot lid of sprayer more, and internal structure is complicated, and processing difficulties is installed trouble.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of and be arranged in the sprayer piston component, the built-in safety valve of hand-held atomizer simple in structure, safe in utilization, reliable.
The technical scheme of the built-in safety valve of hand-held atomizer of the present invention is: comprise kettle body and pot lid, be provided with suction hose and pressure measuring cylinder in the kettle body, be provided with piston in the pressure measuring cylinder; Piston connects inflates handle, and the bottom of pressure measuring cylinder is provided with the water shutoff valve block, is shaped on water channel in the pot lid; Water channel connects suction hose, and a side on pot lid top is provided with shower nozzle, and shower nozzle is communicated with water channel; The opposite side on pot lid top is provided with handle, is provided with in the handle to pull plate and be connected with the switch of shower nozzle, and block is arranged at the pot lid top; It is characterized in that being shaped on stepped mesopore in the described piston, be provided with ball sealer in the stepped mesopore, the ball sealer rear end connects spring; Spring withstands on inflates negative winding stem, and the rear end of piston is shaped on steam vent, and the front end of piston is shaped on air admission hole.
The built-in safety valve of hand-held atomizer of the present invention, operating pressure are 2.5bar, and pressure limiting pressure is 2.5-3bar.Inflate when pressurizeing, because the pressure in the initial kettle body is little, piston moves downward, the gas of compressing piston nose, and the precompression of spring is greater than the pressure in the kettle body at this moment, and piston compressing gas is opened the water shutoff valve block, gets in the kettle body; Air pressure in the kettle body raises, and when reaching the precompression of spring, the air pressure after piston nose compression this moment equates with the kettle internal pressure; Continue pressurization, the air pressure of piston nose then must overcome the pressure of spring; Force ball sealer to rise; The piston mesopore is opened, and the Compressed Gas that makes piston nose releases from the mesopore of piston, reaches the safety requirements of protection kettle body.But the air pressure in the kettle is owing to the single effect of water shutoff valve block, and pressure can not be affected.This programme only needs in piston, to open the system mesopore, and the sealing ball and spring is set in mesopore, just can reach the work of pressure release, and is simple in structure, safe in utilization, reliable.
The built-in safety valve of hand-held atomizer of the present invention, the described negative winding stem of inflating is installed coupling head, and coupling head is through the piston that is threaded, and spring withstands on the coupling head head, and coupling head has been arranged, and it is convenient that the handle of inflating connects piston, is threaded conveniently.Described piston crown is shaped on two catch, forms groove between two catch, and O-ring seals is installed in the groove; O-ring seals contacts with the inwall of pressure measuring cylinder; The spacing of two catch makes O-ring seals with reciprocating motion of the pistons the time greater than the diameter of O-ring seals, lags behind piston.
