Description
Technical field
This utility model relates to sprayer art, particularly to a kind of hand-held atomizer inflator.
Background technology
Aerosol apparatus is to utilize suction effect that liquid medicine or other liquid are become vaporific, is ejected into the utensil on other objects equably.Hand-held atomizer is mainly used in spraying flowers, potted plant etc., traditional aerosol apparatus, water in staving is all sprayed out to constantly pressurizeing in sprayer barrel body by it by inflator again, but the continuous pressurization due to inflator, air pressure in staving can constantly rise, without controlling the pressure added well, then staving can be excessive and damage due to pressure.
At present, notification number is that the Chinese patent of CN202290394 discloses a kind of Handheld sprayer built-in relief valve, it includes kettle body and pot lid, absorption tube and pressure measuring cylinder it is provided with in kettle body, piston it is provided with in pressure measuring cylinder, piston connects inflates handle, the bottom of pressure measuring cylinder is provided with water shutoff valve block, its piston is shaped with stepped mesopore, it is provided with ball sealer in stepped mesopore, ball sealer rear end connects spring, spring top is inflating negative winding stem, the rear end of piston is shaped with steam vent, the front end of piston is shaped with air inlet, the purpose reaching pressure release is coordinated by the spring in piston and ball sealer, prevent kettle body swollen bad.But, owing to ball sealer is linear contact lay with contacting of stepped mesopore, ball sealer and stepped mesopore can produce abrasion and corrosion when using for a long time, easily there is pit in so ball sealer surface, stepped mesopore is also easily generated breach in the limit that ball sealer contacts, therefore sealing can be caused tight, affect the service life of pressure measuring cylinder.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide the hand-held atomizer inflator of a kind of good airproof performance length in service life.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of hand-held atomizer inflator, including cylinder and the handle of inflating being located in cylinder, the described front end inflating handle is provided with pressure release cylinder, the front end of described pressure release cylinder is provided with breather cheek valve, described pressure release cylinder is that hollow is arranged, the front end of described pressure release cylinder is provided with air inlet, the barrel of pressure release cylinder is provided with steam vent, the sealing-plug for blocking air inlet it is provided with in described pressure release cylinder, the rear end of described sealing-plug connects to have and withstands on the spring inflating on negative winding stem, it is provided with tapered sidewalls with air inlet joint in described pressure release cylinder, the front end of described sealing-plug is provided with the tapering point coordinated with tapered sidewalls.
By above-mentioned setting, inflate handle in cylinder during pull effect due to breather cheek valve realize toward inflation in aerosol apparatus kettle body, in order to ensure that air pressure that inflator injects can not over loading, it is provided with pressure relief, the volume taken here for minimizing pressure relief makes close structure, therefore pressure relief is located at inflate the front end of handle and breather cheek valve integral, the cavity of pressure release cylinder forms pressure-releasing chamber, sealing-plug props up air inlet and realizes sealing, here spring is to the certain precompression of sealing-plug, when the air pressure in aerosol apparatus kettle body is low, precompression is more than the interior thrust to sealing-plug of kettle body, sealing-plug will not move toward when inflating in kettle body inflating handle, inflator works just as normal inflator；When in kettle body to the thrust of sealing-plug more than precompression time, inflate in kettle body again, then sealing-plug is by moving in thrust and opening air inlet, gas enters from air inlet and discharges the purpose reaching pressure release from steam vent, here the form of sealing-plug is used, pressure release tube inner chamber is tapered sidewalls near the sidewall of air inlet position, opening is gradually reduced, just the tapering point on sealing-plug and tapered sidewalls fit tightly, and contact in face between the two, it is effectively guaranteed sealing between the two, simultaneously when tapering point or tapered sidewalls have a little damage or abrasion, owing to the sealing of sealing-plug and tapered sidewalls is wide, sealing-plug gas leakage is not interfered with yet, the sealing of relief valve is effectively ensured, thus the service life of inflator is longer.
Preferably, described breather cheek valve includes being located between the catch of pressure release cylinder front end, catch and pressure release cylinder front end the annular groove formed, the unidirectional valve plug being located in annular groove, and described catch is provided with breach.
By above-mentioned setting, check valve plug sleeve is located in annular groove, there is gap between the two, when inflate handle move downward relative to inflator inflate time, unidirectional valve plug moves up the lower end being close to pressure release cylinder, forms airtight chamber, it is ensured that gas is pressed in aerosol apparatus kettle body；When inflate handle move upward relative to inflator time, unidirectional valve plug moves down is close to catch, and the breach on catch is used for air inlet, and gas enters from the external world and enters inflator lower end inflator and from breach, for inflate handle press down time toward air inlet in kettle body.
Preferably, described catch is provided with taper surface away from one end of pressure release cylinder.
By above-mentioned setting, the taper surface on catch towards the bottom of inflator, can effectively reduce inflate handle be pressed downward against time resistance, have certain gas guide effect simultaneously, make gas quickly promote check valve to move the bottom being close to relief valve beyond the Great Wall.
Preferably, described pressure release cylinder is threadedly connected to inflate the front end of handle.
Removably connected by above-mentioned setting, pressure release cylinder and realization between handle of inflating, it is possible to change at any time.
Preferably, inflate described in and be provided with reinforcement rib along its length on the outer wall of handle.
By above-mentioned setting, during inflating, bear main pressure be susceptible to fracture owing to inflating handle, therefore arrange along its length and strengthen rib and ensure to inflate the intensity of handle.
Preferably, inflate described in and be circumferentially with the reinforcing rib of connection reinforcement rib along it on the outer wall of handle.
By above-mentioned setting, reinforce rib and effectively adjacent reinforcement rib is linked together, enhance the intensity strengthening rib, thus ensure that and inflate the intensity of handle.
In sum, this utility model in contrast to the tapering point having the beneficial effect that on sealing-plug of prior art and tapered sidewalls fits tightly, and contact in face between the two, it is effectively guaranteed the best sealing, simultaneously when tapering point or tapered sidewalls have a little damage or abrasion, owing to the sealing of sealing-plug and tapered sidewalls is wide, do not interfere with sealing-plug gas leakage yet, the sealing of relief valve is effectively ensured, thus the service life of inflator is longer.
