Specifically, the working process of the first one-way valve is as follows: the first stop ball 305a is located at the lower end of the first limiting post 3027 and at the upper end of the through hole at the lower section of the first outer sleeve 304a, and in a natural state, the first stop ball 305a is plugged at the upper end of the through hole at the lower section of the first outer sleeve 304a by gravity, so that it cannot be communicated with the through hole on the first limiting post 3027 through which the liquid flows, and thus cannot be communicated with the liquid storage area 307. When the power part 1 sucks out the gas in the liquid storage area 307, the gas pressure in the liquid storage area 307 is reduced, along with the continuous operation of the power part 1, the gas pressure in the liquid storage area 307 is continuously reduced, and the gas pressure in the liquid storage bottle 401 is unchanged, because the pressure of the first stop ball 305a near the liquid storage area 307 is lower than the pressure near the liquid delivery conduit 402 side, the first stop ball 305a receives upward acting force, when the gas pressure in the liquid storage area 307 is reduced to a certain extent, so that the upward acting force received by the first stop ball 305a is greater than the gravity of the self, the first stop ball 305a moves upward and leaves the upper end of the lower section through hole of the first outer sleeve 304a, and opens the lower section through hole of the first outer sleeve 304a, so that the liquid in the liquid storage bottle 401 sequentially passes through the lower section through hole of the liquid delivery conduit 402, the first outer sleeve 304a lower section through hole, the first stop post 3027 and the center post 3023 for sucking the liquid into the liquid inlet port 3023 through the liquid inlet section of the liquid storage conduit 307, and the upper section 3023 can flow through the first outer sleeve 304a through the upper section through hole of the liquid inlet pipe 402; when the power part 1 blows air into the liquid storage area 307, the air pressure in the liquid storage area 307 is increased, and because the pressure of the first stop ball 305a near one side of the liquid storage area 307 is gradually increased, the upward acting force exerted by the first stop ball 305a is gradually reduced, and when the upward acting force exerted by the first stop ball 305a is smaller than the gravity of the first stop ball 305a, the first stop ball 305a moves downwards under the action of gravity to block the upper end of the lower section through hole of the first outer sleeve 304a again, and the liquid in the liquid storage bottle 401 cannot enter the liquid storage area 307, so that the liquid storage area 307 can suck the liquid.
Further, as shown in fig. 5 to 10, the liquid storage area 307 further has a bypass port 3024, the bypass port 3024 is located at a lower portion of the liquid storage area 307, and the bypass port 3024 communicates with an external liquid using device through a bypass pipe 3025.
Further, the bypass port 3024 is located at a lower portion of the lower cover 302, the bypass port 3025 is in communication with the bypass port 3024, and the bypass port 3025 is disposed in parallel with the liquid storage area 307.

As shown in fig. 5 to 10, when the upper cover 301 and the lower cover 302 are relatively fastened together, the second limiting post 3015 can be inserted into the bypass pipe 3025, the second stop ball 305b is located in the bypass pipe 3025, a second outer sleeve 304b is disposed at the periphery of the second stop ball 305b, the second limiting post 3015 is inserted into the receiving cavity 3041 in the second outer sleeve 304b from the upper end of the second outer sleeve 304b, the second stop ball 305b is located below the second limiting post 3015, and the second stop ball 305b is received in the receiving cavity 3041 in the second outer sleeve 304 b. The flange 3043 of the second outer sleeve 304b is clamped at the upper portion of the bypass pipe 3025, the main body of the second outer sleeve 304b is filled in a gap between the bypass pipe 3025 and the second limiting column 3015, and the gap is filled and sealed by interference fit or the like.

Specifically, the working process of the second one-way valve is as follows: the second through-stop ball 305b is located at the lower end of the second limiting post 3015 and at the upper end of the through hole at the lower section of the second outer sleeve 304b, and in a natural state, the second through-stop ball 305b is plugged at the upper end of the through hole at the lower section of the second outer sleeve 304b by means of self gravity, so that the through hole at the lower section of the second outer sleeve 304b cannot be communicated with the through hole for flowing liquid on the second limiting post 3015, and cannot be further communicated with an external liquid using device. When the power part 1 sucks out the gas in the liquid storage area 307, the pressure of the gas in the liquid storage area 307 is reduced, so that the pressure of the second through-stop ball 305b near the liquid storage area 307 is lower than the pressure near the second limiting post 3015, and at this time, the second through-stop ball 305b is subjected to downward force, and is tightly blocked at the upper end of the lower section through hole of the second outer sleeve 304b, so as to block the communication between the external liquid using device and the liquid storage area 307. When the power part 1 blows air into the liquid storage area 307, the air pressure in the liquid storage area 307 is increased, so that the pressure of the second stop ball 305b near the liquid storage area 307 is higher than the pressure near the second limiting post 3015, at this time, the second stop ball 305b is subjected to upward acting force, and as the power part 1 continuously blows air into the liquid storage area 307, when the upward acting force applied by the second stop ball 305b is higher than the gravity of the power part, the second stop ball 305b moves upwards and leaves the upper end of the lower section through hole of the second outer sleeve 304b, so that the bypass port 3024 can be communicated with an external liquid using device through the bypass pipe 3025, the second outer sleeve 304b, the second limiting post 3015 and the liquid outlet channel 3014 in sequence, and then the liquid in the liquid storage area 307 can be discharged to the external liquid using device through the bypass pipe 3025, the second outer sleeve 3015 and the liquid outlet channel 3014 in sequence, thereby realizing liquid discharge. On the other hand, in this process, when the power unit 1 starts to blow air into the liquid storage area 307, the air pressure in the liquid storage area 307 will gradually increase, and once the upward acting force applied to the first stop ball 305a is smaller than the gravity force thereof before the air pressure in the liquid storage area 307 is equal to the air pressure in the liquid storage bottle 401, the first stop ball 305a will move downward under the action of gravity force thereof and tightly block the upper end of the lower section through hole of the first outer sleeve 304a, so that the liquid in the liquid storage bottle 401 cannot enter the liquid storage area 307. It can be seen that, during the process of blowing the gas into the liquid storage area 307 by the power unit 1, the first blocking ball 305a falls back first to close the liquid suction channel, and then, the power unit 1 needs to continue blowing the gas into the liquid storage area 307 to make the second blocking ball 305b rise to open the liquid discharge channel, that is, during the process of blowing the gas into the liquid storage area 307 by the power unit 1, the first valve and the second valve are not opened at the same time; similarly, when the power unit 1 sucks out the gas in the liquid storage area 307, the second valve is always subjected to downward force and keeps the closed state; the first valve is openable after a period of inhalation of the power section 1, and the first valve and the second valve are likewise not opened at the same time.

Further, as shown in fig. 5 and 9, the central column 3023 has an upper end surface and an annular side wall, and a liquid discharge port is disposed at a connection portion between the upper end surface and the annular side wall, the liquid discharge port is in communication with a through hole in the central column 3023 through which liquid passes, and the liquid discharge port is disposed so that the liquid entering the liquid storage area 307 through the central column 3023 is not easily sucked out of the liquid storage area 307 by the power portion 1 through the first gas transmission port 3013.
Further, the upper end of the second side wall 3022 is further provided with a flange 3026, when the upper cover 301 and the lower cover 302 are fastened together relatively, the flange 3026 is attached to the edge of the upper cover 3011 of the upper cover 301, and the upper cover 301 and the lower cover 302 can be tightly connected together through the flange 3026.

In this way, the gas that the power unit 1 delivers to the liquid storage area 307 will sequentially pass through the connection unit 2, the second air guide elbow 3016, the first air delivery port 3013, the expansion end 3031, and the second air delivery port 3033 to enter the liquid storage area 307. The liquid in the liquid storage area 307 is effectively prevented from being sucked into the air bag 104 in the power part 1 by the arrangement of the backflow preventing member 303.
Preferably, the first gas delivery port 3013 and the second gas delivery port 3033 are not on the same straight line in the vertical direction, that is, in the use state, the projections of the first gas delivery port 3013 and the second gas delivery port 3033 in the vertical direction are not overlapped.
