The tube 3 has a sealing valve 26 which is removably connected with the second tank 28. The tank 28 is connected to a regulator which may reduce the pressure of the air supplied from the second tank 28 to a predetermined low pressure level. With the second tank 28 disconnected from the first tank 6, the low-pressure air is provided to an atomizer 11 for atomization of medicine in inhalation treatment. ## Claims ### Claim 1 An atomizer system comprising: a main unit operative to charge a portable unit with an amount of pressurized air, said main unit including: an air compressor for generating pressurized air, a first pressure accumulation tank for storing a volume of pressurized air generated by said compressor, and at least one air tube for conducting said pressurized air air from said first pressure accumulation tank to an air outlet; and a portable unit which includes: a second pressure accumulation tank for accepting an air charge from said first pressure accumulation tank, said second pressure accumulation tank having at least one sealing valve which is detachably connectable to said air outlet of said first pressure accumulation tank, a regulator for decompressing the high-pressure air stored in said second pressure accumulation tank to reduce the pressure thereof and to generate low-pressure air having a predetermined pressure, and at least one atomizer communicating with said regulator on the downstream side thereof for atomizing liquid by means of said low-pressure air. ### Claim 2 (depends on 1) The atomizer system according to claim 1, wherein said atomizer is removably mounted on said regulator via said valve and said air tube. ### Claim 3 (depends on 1) The atomizer system according to claim 1, wherein said main unit further comprises a filter unit for cleaning said high-pressure air released from said first pressure accumulation tank, thereby providing said second pressure accumulation tank with clean high-pressure air. ### Claim 4 (depends on 3) The atomizer system according to claim 3, wherein said second pressure accumulation tank of said portable unit has a short cylindrical configuration and has on the top thereof said regulator and said atomizer, and a bottom which is separable from the rest of said portable unit. ### Claim 5 (depends on 4) The atomizer system according to claim 4, wherein said filter unit includes: a multiplicity of filters for removing different kinds of particles, said filters each having indicator for indicating if they are choked or not; a mount in the form of plate for mounting thereon said filters in series; and an observation window formed in said mount for monitoring said indicators of said filters, said observation window formed at a position suitable for said observation. ### Claim 6 (depends on 5) The atomizer system according to claim 5, wherein said filter unit includes a dust filter for removing dust in the air, an oil mist filter for removing liquid oil particles, and an odor filter for removing bad odor particles. ### Claim 7 An atomizer system comprising: a movable main unit which includes: an air compressor for generating high-pressure air, a pressure accumulation tank for storing a volume of high pressure air generated by said compressor, at least one regulator for reducing the pressure of said high-pressure air in said pressure accumulation tank to a predetermined low pressure, a multiplicity of air outlets communicated with said regulator for delivering said low-pressure air stored in said regulator, a multiplicity of valves mounted in said air outlets, one for each air outlet, for controlling the flow of air that passes through said air outlets, and at least one atomizer for atomizing liquid by means of said low-pressure air. ### Claim 8 (depends on 7) The atomizer system according to claim 7, wherein said main unit further comprises a removable air filter unit for cleaning said high-pressure air delivered from said pressure accumulation tank, thereby supplying clean high-pressure air from said air outlets. ### Claim 9 (depends on 8) The atomizer system according to claim 8 further comprising a timer which is capable of controlling said valves individually such that said low-pressure air is released from said air outlets for only prescribed periods of time. ### Claim 10 (depends on 9) The atomizer system according to claim 9, wherein said filter unit includes: a multiplicity of filters for removing different kinds of particles, said filters each having indicator for indicating if they are choked or not.; a mount in the form of plate for mounting thereon said filters in series; and an observation window formed in said mount for monitoring said indicators of said filters, said observation window formed at a position suitable for said observation. ### Claim 11 (depends on 10) The atomizer system according to claim 10, wherein said filter unit includes a dust filter for removing dust in the air, an oil mist filter for removing liquid oil particles, and an odor filter for removing bad odor particles. ### Claim 12 (depends on 11) The atomizer system according to claim 11, wherein each of said multiplicity of air outlets is provided with a regulator capable of individually regulating the pressure of the air released from said air outlet.
