  • Portable automated misting device
    Patent number: 6264120
    Abstract: A portable automatic misting device (20) uses a misting device assembly (38) to automatically disperses a mist (36). The misting assembly (38) includes a hollow cylinder (40) that forms a liquid reservoir (50) that is in fluid communication with a one-way valve (76,102) that permits liquid flow into the reservoir (50). The reservoir (50) has fluid communication with a misting nozzle (34) through a hollow plunger rod (28). A plunger (42), a spring (48) and a portion of the hollow plunger rod (28) are located inside the hollow cylinder (40). The spring (48) is biased to move the plunger (42) and the hollow plunger rod (28) to automatically shrink the liquid reservoir (50). In another embodiment, the plunger rod (28) is solid and the reservoir (50) has fluid communication with the misting nozzle (34) through a second one-way valve (106) that permits liquid flow out of the reservoir (50).

  • Portable automatic misting device
    Publication number: 20010004091
    Abstract: A portable automatic misting device (20) uses a misting device assembly (38) to automatically disperse a mist (36). The misting assembly (38) includes a hollow cylinder (40) that forms a liquid reservoir (50) that is in fluid communication with a one-way valve (128) that permits liquid flow into the reservoir (50) from a liquid container (118). The reservoir (50) has fluid communication with a misting nozzle (34) through a hollow plunger rod (28). A plunger (42), a spring (48) and a portion of the plunger rod (28) are located inside the hollow cylinder (40). The spring (48) is biased to move the plunger (42) and the plunger rod (28) to automatically shrink the liquid reservoir (50). A second one-way valve (122) permits a passage of air into the liquid container (118) to equalize pressure therein.
