If in addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and cannot manage Solution is its relative importance of indication or suggestion or the quantity for implicitly indicating indicated technical characteristic.Define as a result, " the One ", the feature of " second " can explicitly or implicitly include at least one of the features.

FIG. 1 to FIG. 3 is please referred to, the atomising device of the utility model embodiment mainly includes material room 10, suction pipe 20, spray head 30, gas chamber 40, tracheae 50, piston 60, elastic component 70, check valve 80 and pulling mechanism 90.

The top of spray head 30 is equipped with the lead-in chamfered 31 of guidance air-flow, offers discharge hole 32 in lead-in chamfered 31, guides 31 lower section corresponding position of inclined-plane is equipped with venthole 33.The diameter of venthole 33 is 0.3mm ~ 0.4mm, preferably 0.35mm；Discharging The diameter in hole 32 is 0.3mm ~ 0.4mm, preferably 0.35mm.The bottom of material room 10, the other end and discharging are led in 20 one end of suction pipe Hole 32 is connected to.The gas sprayed from venthole 33 is formed about the air-flow of high speed in lead-in chamfered 31, and then makes lead-in chamfered 31 On discharge hole 32 at formed subnormal ambient, and then will expect room 10 in Material extraction, finally by discharge hole 32 spray, gone out The air-flow that stomata 33 sprays dispels, and forms atomization.

Gas chamber 40 is connected to by tracheae 50 with the venthole 33 on spray head 30, is additionally provided with air inlet on gas chamber 40.Check valve 80 are set at air inlet, and check valve 80 is open-minded in 40 air inlet of gas chamber, is closed in outlet.Piston 60 is set in gas chamber 40；Bullet Property 70 one end of part act on piston 60, the other end acts on gas chamber 40, and elastic component 70 pushes piston 60, makes the gas in gas chamber 40 It is discharged from venthole 33.The utility model embodiment does not need to generate forced draft using electric air pump, saves product manufacturing Cost；The utility model embodiment uses negative-pressure atomizing, and without using propellant, (propellant is mostly liquefied gas, in atmospheric boiling point Lower than room temperature, vapour pressure is high), it does not need to achieve the purpose that be atomized material by aerosol, substantially increasing Material, (Material can For chemicals such as fragrance, drugs) safety in utilization and stability, and then expand the utility model embodiment apply model It encloses；The utility model embodiment can be applied in the equipment such as fragrance machine, fragrant atmosphere machine, urine pocket sterilizer.Pulling mechanism 90 effect with On piston 60, for pulling piston 60 to enter extraneous gas in gas chamber 40 from air inlet.

The working principle of the utility model are as follows: pass through compression elastic piece 70(compressed spring), elastic component 70 pushes piston 60, Gas chamber 40 generates pressure and air-flow, sprays from the venthole 33 of spray head 30, and discharge hole 32 is because air-flow is negative pressure, to pass through suction Pipe 20 draw Material, Material be sucked up come after, by venthole 33 spray air-flow dispel mist formation, thus reach atomization diffusion. The atomization quantity of the utility model embodiment can be according to the size of gas chamber 40, elastic component 70(compressed spring) compression travel, spray The size of nozzle aperture is adjusted, to adapt to the demand of varying environment.Preferably, the elastic component 70 of the utility model pushes 60 energy of piston It generates pressure and is greater than 20kp, tolerance is greater than 2L air pressure air-flow per minute；For example, the diameter of gas chamber 40 is 60mm, 60 row of piston Journey is 35mm, and piston 60 promotes time about 4s, generates about 0.0001 cubic metre of gas volume.

As an implementation, pulling mechanism 90 includes connecting rod 91, transmission gear 92 and motor sub-assembly, connecting rod 91 It is connect with piston 60, connecting rod 91 is equipped with corresponding sawtooth, and transmission gear 92 is equipped with half coaxial gear 95, connecting rod 91 It is engaged by sawtooth with half gear 95 of transmission gear 92, motor sub-assembly drives transmission gear 92 to rotate and then passes through connecting rod 91 Pull piston 60.

As an implementation, motor sub-assembly includes micro motor 93 and multiple is successively nibbled by what micro motor 93 drove The reduction gearing 94 of conjunction.The utility model embodiment passes through 93 compression elastic piece 70(compressed spring of micro motor) push piston 60, generate stable forced draft, will not because cell voltage is low and stream pressure is unstable, cause atomizing effect bad and mist Change amount is unstable；The energy consumption of micro motor 93 is more much lower than battery air pump and micro air pump, is powered using battery, installation is answered With conveniently.

As an implementation, pulling mechanism 90 further includes limit switch 97 and half gear 95 set on transmission gear 92 On locating rod 96, limit switch 97 is correspondingly arranged at the side of transmission gear 92, and the locating rod 96 on transmission gear 92 goes to limit When on bit switch 97, motor sub-assembly stop motion.The course of work of the utility model embodiment are as follows: motor sub-assembly (micro motor 93 rotations, are driven by multiple reduction gearing 94) the band rotation of nutating gear 92；Half gear 95 above transmission gear 92 starts The sawtooth in connecting rod 91 is engaged, connecting rod 91 is pulled, thus with 60 compression elastic piece 70(compressed spring of piston)；It is single at this time In the open state to valve 80, gas chamber 40 enters gas；When half gear 95 above transmission gear 92 goes to hypodontia face, elastic component 70 It resetting and pushes piston 60, generate pressure and air-flow, check valve 80 is in close state at this time, and air-flow is discharged from venthole 33, when Locating rod 96 on transmission gear 92 is gone on limit switch 97, indicates that half gear 95 on transmission gear 92 has completed one Period, motor sub-assembly stop operating；Air-flow leads into spray head 30 by tracheae 50, and the venthole of spray head 30 is passed through in air-flow air pressure 33 discharges, drain by lead-in chamfered 31, and discharge hole 32 is in negative pressure state, and Material is sucked into discharge hole 32 by suction pipe 20 Place, Material dispel into spray pattern by the air-flow that the slave venthole 33 passed through sprays；It resets and completes to elastic component 70, forced draft Stop discharge, stop the suction of Material, completes the primary atomization period at this time.

Half gear 95 above the locating rod 96 of the utility model embodiment, position-sensing switch and transmission gear 92, makes piston A complete cycle is completed in 60 movements, even if battery is in the state of low-voltage, 93 revolving speed of micro motor is slack-off, will not influence The stream pressure that elastic component 70 generates when resetting, so that the atomizing effect of spray head 30 be made to stablize.

As an implementation, elastic component 70 is compressed spring.In addition, elastic component 70 can also be elastic slice etc..

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and their equivalents.
