(13) Also included in a diffusion device 6, where the diffusion device 6 comprises a container 61 and a diffuser 62. The container 61 has an end connected to a circumference of the diffuser 62 so that a bottom of the diffuser 62 is received and held in an interior of the container 61. The diffuser 62 is provided, on the circumference thereof, with a retention section 621. The retention section 621 is engageable with and thus coupled to the retention device 5 to have the diffuser 62 clamped and retained between the retention device 5 and the coupling section 11. The diffuser 62 is provided, on the circumference thereof, with a gas entrance section 622. The gas entrance section 622 has a side that is provided with a gas entrance passage 6221. The gas entrance section 622 is a gas entrance section in the form of an inclined surface to facilitate mutual tight engagement between the gas entrance section 622 and the gas conveyance hole 12 so that the gas entrance passage 6221 is set in tight connection with the gas conveyance hole 12. The gas entrance passage 6221 has an end formed in a surface of the gas entrance section 622 and an opposite end of the gas entrance passage 6221 extends to a bottom of the diffuser 62 and an end of the gas entrance passage 6221 has a diameter that is greater than that of an opposite end of the gas entrance passage 6221. The diffuser 62 is provided, on the bottom thereof, with a liquid guiding device 623. The liquid guiding device 623 has an end connected to the bottom of the diffuser 62. The liquid guiding device 623 has an opposite end extending to a location adjacent to a bottom of the container 61. The liquid guiding device 623 is provided, in a circumference thereof, with an atomization hole 6231. The atomization hole 6231 has an end communicating with the liquid guiding device 623, while an opposite end of the atomization hole 6231 is arranged at a location adjacent to the opposite end of the gas entrance passage 6221. The diffuser 62 has a circumference that is coupled to the coupling section 11 and the gas conveyance hole 12 is in tight connection with the gas entrance passage 6221. The diffuser 62 is provided, in a top end thereof, with an exit opening 624. The diffuser 62 is provided, in the interior thereof, with a slow flowing device 625 for flowing down the flowing speed of pressurized gas and filtering off atomized objects having large particles to allow only fine atomized substance to spray out, thereby improving an effect of atomization.

(14) In the above-described gas supply device 1, the gas supply device 1 is connected, at the circumference thereof, to an electrical wire 7 so that electrical power can be supplied through the electrical wire 7 to the gas supply device 1. Further, the gas supply device 1 is provided, in the interior thereof, with a power supply device (not shown) so that in case of power failure, the power supply may maintain continuous supply of electrical power to the gas supply device 1.

(15) In the above-described gas inlet section, the gas inlet section is connected to a sponge 8 for filtering off impurities entraining external air.

(16) In the above-described container 61, the container 61 receives and holds therein a liquid, and the liquid may comprises perfume, disinfection liquid, or insect expellant liquid.

(17) Referring to FIGS. 2, 3, and 7-9, which are respectively an exploded view of the present invention, a schematic view illustrating inside details of the gas supply device of the present invention, a schematic view illustrating a use condition of the present invention, an enlarged view showing the atomization hole of the present invention, and an enlarged view showing the slow flowing device of the present invention, as shown in the drawings, the gas outlet section 21 is coupled to the compression element 3 and the compression element 3 is coupled to the gas conveyance hole 12 so that external gas, when drawn in through the gas inlet section of the gas inlet device 2, first passes through the sponge 8 for filtering and removal of impurities and then enters the interior of the gas inlet device 2 to be fed through the gas outlet section 21 into the compression assembly 3 to allow the compression assembly 3 to compress the gas to provide pressurized gas that is then fed to the gas conveyance hole 12. The gas conveyance hole 12 is in connection with the gas entrance passage 6221 and one end of the gas entrance passage 6221 is provided at the surface of the gas entrance section 622, while an opposite end extends to the bottom of the diffuser 62 so that the pressurized gas that is fed from the gas conveyance hole 12 to the gas entrance passage 6221 passes through the gas entrance passage 6221 to allow the pressurized gas to be introduced into the container 61. Further, due to the diameter of one end of the gas entrance passage 6221 is greater than that of another end so as to induce the Venturi effect, where the flow speed of a fluid that passes through a narrowed cross section would be increased and the pressure rises. As such, when the pressurized gas flows from one end of the gas entrance passage 6221 to the opposite end of the gas entrance passage 6221 and discharged therefrom, the flow speed and the pressure thereof would be increased. When the pressurized gas is introduced into the container 61, due to the opposite end of the gas entrance passage 6221 being adjacent to the atomization hole 6231, the pressurized gas flowing the location that is adjacent to the atomization hole 6231 would induce a negative pressure at such a site, such that the negative pressure zone induces a suction force due to the outside atmospheric pressure being relatively greater, whereby the liquid contained in the container 61 is sucked and drawn through the liquid guiding device 623 to the atomization hole 6231 and the liquid is then subjected to atomization by the atomization hole 6231 to have the liquid converted into atomized liquid.

(18) Further, when the pressurized gas is introduced into the container 61, since the container 61 is a closed space, the pressurized gas is only allowed to flow out through the exit opening 624. When the pressurized gas flows toward the exit opening 624, the atomized liquid is also driven thereby to the exit opening 624, whereby the pressurized gas and atomized liquid are fed out. Further, the slow flowing device 625 helps increase the time interval that is necessary for the pressurized gas to flow to the exit opening 624 in order to prevent the situation where the liquid is just atomized while the pressurized gas has already fed out through the exit opening 624 and also functions to filter off large particles of the atomized gas, allowing only fine particles to be discharged so as to make better atomization. In this way, automatic spraying can be achieved effectively.

(19) When the pressurized gas and the atomized liquid are discharged through the exit opening 624, the flow driving device 4 simultaneously drives gas that is drawn in from the outside through the air ingress section 14 toward one side of the gas supply device 1 so as to blow the atomized liquid to a further location, making the atomized liquid spread to a further location, where the term further location is such that for atomized liquid that is driven out by the pressurized gas to cover a distance of for example one meter, the flow driving device 4 so arranged to blow the external gas to the atomized gas would help spread the atomized liquid to cover a range more than one meter in distance.

(20) It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

(21) While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
