Figure 2 is a front view of a second embodiment of a life-saving breathing device in accordance with the present invention;

Figure 3 is an exploded perspective view of a filter bottle in accordance with an embodiment of the present invention;

Figure 4 is a cross-sectional view of the filter bottle of Figure 3;

Figure 5 is an exploded perspective view of a breather in accordance with an embodiment of the present invention;

Figure 6 is a perspective view of the breather of Figure 5; and

Figure 7 is a perspective view of the lifesaving breathing device as shown either in Figure 1 or in Figure 2.

[0015] A first and a second embodiment of a lifesaving breathing device in accordance with the present invention are shown respectively in Figures 1 and 2. The first embodiment has no oxygen tank, but the second embodiment has one for an additional use. The two embodiments each comprise a motor 1, a battery 10 furnishing power to the motor 1, and a switch 11 located on a faceplate for turning on and off the motor 1 as shown in Fig. 7. The motor 1 has a shaft connected with shift gears housed in a gear case 12 and then with a disc 13, and an eccentric rod 14 has its top end connected with the disc 13 and its bottom end connected with the top end of shrinkable bellows 20 fixed on top of a filter bottle 2. The motor 1 moves the bellows 20 up and down via the disc 13 and the eccentric rod 14, giving rise to sucking force in the filter bottle 2 so as to suck air therein from the outside.

[0016] The filter bottle 2 shown in Figs. 3 and 4 has a bottle body 21 and a hollow interior 210, two opposite notches 211, 211 in a top inner wall of the bottle body 21 for other components to fit in to be stabilised, a plurality of through holes 212 in its vertical wall for L-shaped inlet tubes 22 to insert therein so as to be positioned in its hollow interior 210 and immersed partly in a water filter layer 23 on a bottom 213 so that air entering from outside through the tubes 22 may be eliminated of tiny dust by the water.

[0017] As it is a common phenomenon that air bubbles may arise when air goes through water, this device has three active carbon filter layers 25 positioned in an upper portion of the hollow interior 210 of the bottle 2, and two minute nets 240, 241 are positioned under the active carbon filter layers 25 to prevent very tiny particles from moving up through them owing to extremely minuteness of the net meshes. The two nets 240, 241 are held with a silicon gel ring 242, having respectively two opposite projecting edges 243, 243 to fit through two opposite sideway holes 244 of the silicon gel ring 242. A ring 245 is provided to float on top of the water in the bottle 2, augmenting the water surface density so as to lessen water waving movement, preventing water from splashing upward. If the filter bottle 2 should be declined, water movement would also be hampered.

[0018] Three layers of the active carbon filter layers 25 is used in these embodiments of the invention, but any plural number of the layers 25 can be used practically. Each active carbon filter layer 25 is supported by a shallow disc 251 having a plurality of large netted holes 250, and two opposite projecting edges 252, 252 to engage in the two opposite notches 211 of the bottle 2 for positioning the shallow disc 251 together with the active carbon filter layer 25.

[0019] An air guider 26 is provided, positioned just on the highest active carbon filter layer 25, and having a bottom layer 260 bored with a plurality of air sucking holes 261 closed by thin flaps 263 which can be swung open for purified air to go through. When the bellows is in motion, the thin flaps 253 can only allow air to go in, not to go out therethrough. Then the air entering therethrough flows through a sideway hole 262, a guide tube 280, the air outlet tube 27 and finally into the air tank 3. A bottle cap 28 is provided to close the top of the bottle body 21, having a female thread to engage a male thread 215 of the bottle body 21, fixing firmly the bottom of the bellows 20 on top of the bottle body 21. Thus, air sucked in is purified and then sent into the air tank 3 when the bellows 20 is in motion.

[0020] The purified air entering into the air tank 3 cannot flow out, stopped by a stop valve 30 fixed on an air outlet tube 271 and an adjusting valve 32 fixed on the outlet 31 of the tank 3, enabling a user to adjust the volume of the air flowing out of the valve 32. In case of an oxygen tank 4 being additionally attached, a stop valve 40 is provided at the bottom of the tank 4 and an adjusting valve 42 is provided at an outlet 41 to prevent a user from being harmed by an excessive high pressure of the oxygen coming out of the tank 4.

[0021] A moisture bottle 5 is provided, having its interior 50 connected with the air tank 3 or the oxygen tank 4 with guide tubes 33, 43. The interior 50 contains a little water 51 for wetting air or oxygen. The bottle 5 also has a test hole 52 for inserting a test tube, and an outlet tube 53 provided at an upper portion of the bottle body 51 for connecting a nose tube 60, which has its bottom end connected with a breather 6 able to be inserted in nostrils of a user. And the outlet tube 53 can be formed to have a plurality of branched tubes for several persons to use. The breather 6 has two nostril engagers 61, 61 made of soft silicon gel and just sized to fit in nostrils to prevent outside air from flowing therethrough, and partly connected with each other with an elastic connector 610 so as to let the distance between the two nostrils be adjustable to be used by anyone. The nostril engager 61 also has a center vertical hole for an air supply body 62 to fit therein from underneath through a hole 64 attached with an annular ring in the bottom. The air supply body 62 has a center inlet hole 620 for the branch tube 63 of the breather 6 to fit therein, a plurality of cone-shaped teeth 621 formed around the inlet hole 620, a tooth groove 622 between each two teeth 621, a small hole 623 in a bottom wall 624 under each tooth groove 622 for air exhaled by a user to escape out.

[0022] In the illustrated embodiments, the water filter layer of the filter bottle firstly filters air coming from outside, but it is difficult to breathe purified air directly from the filter bottle because of the separation by the water filter layer. Therefore, electric operation is needed to make it possible for a user to breathe from it. The largest benefit of the electric operation is durability and practicality of the power from the battery, enabling this device usable for a long period of time in an emergency. Complete separation of tiny impurities and the purified air produced thereby and stored in the air tank can attain the desired object.
