The rotation angle of the servo motor 105 can be set in advance. After the trigger switch 204 sends a signal, it is received and recognized by the internal controller of the servo motor 105, and then the controller controls the servo motor 105 to rotate, thereby driving the rotating worm 104 to rotate, and then driving the rotating worm wheel 102 to rotate, and then driving the two bottom liquid storage bins 2 to rotate and swap positions, thereby causing the overflowing liquid storage bin 2 to rotate to the side, and the empty liquid storage bin 2 to rotate to the bottom of the Y-shaped tube 1011 to continue storing liquid.

[0025] See also Figure 1 and Figure 2 A Y-shaped tube 1011 is fixedly connected to the top of the fixed box 101, and the liquid will flow into one of the liquid storage bins 2 through the Y-shaped tube 1011.

During the rotation of the liquid storage bin 2, the switch plate 209 is first slidably connected with the convex plate 1052. During the sliding connection, the switch plate 209 moves toward the inside of the liquid storage bin 2 due to the squeezing effect of the convex plate 1052, thereby moving the sliding rod 208 inward, thereby moving the sealing plate 207 and leaving the sealing state, thereby allowing the liquid inside the liquid storage bin 2 to be discharged through the drain port, drain pipe 211, rotating pipe 212 and conduit 213. The rotating pipe 212 can rotate with the liquid storage bin 2 to avoid the drain pipe 211 from rotating and entangled. After the liquid inside the liquid storage bin 2 is discharged, the liquid storage bin 2 rotates to the position of the compression roller 302.

[0027] See also Figure 1 and Figure 5 The bottom end of the liquid storage bin 2 is fixedly connected with a discharge pipe 211, the bottom end of the discharge pipe 211 is fixedly connected with a rotating pipe 212, and the bottom end of the rotating pipe 212 is fixedly connected with a guide tube 213.

[0029] See also Figure 4 and Figure 5 The side end of the servo motor 105 is fixedly connected to a buzzer plate 1051, and the bottom end of the buzzer plate 1051 is fixedly connected to a convex plate 1052. The side end of the convex plate 1052 can be slidably connected to the switch plate 209. When the trigger 202 starts to rotate and switch, the internal controller of the buzzer plate 1051 receives and identifies the signal, and then controls the internal buzzer of the buzzer plate 1051 to alarm, reminding the medical staff that the liquid storage tank 2 is overflowing. When the overflow reaches a certain number of times, it can be cleaned. Since a drain pipe 211, a rotating tube 212 and a catheter 213 are provided at the bottom of the liquid storage tank 2, the accumulated liquid can be discharged through the pipe and the sewer. The medical staff can make the ventilator continuously collect the accumulated liquid without replacing the liquid cup, saving a lot of operation time.

[0030] In summary, in the utility model, the installer uses the Y-tube 1011 to connect the ventilator liquid accumulation alarm device, and empty the two liquid storage tanks 2, and install the drainage pipe 211, the rotating tube 212 and the catheter 213 at the bottom of the liquid storage tank 2. Then the ventilator can be started, and the liquid will flow into one of the liquid storage tanks 2 through the Y-tube 1011, and then the liquid level inside the liquid storage tank 2 will gradually rise, thereby driving the buoyancy block 203 to rise, and then the trigger 202 will slide upward through the limit of the guide rod 201 and trigger the trigger switch 204, and the trigger switch 204 and the servo The motor 105 is connected by telecommunication, and the servo motor 105 is fixedly connected to the top of the buzzer board 1051. The rotation angle of the servo motor 105 can be set in advance. After the trigger switch 204 sends a signal, it is received and recognized by the internal controller of the servo motor 105, and then the controller controls the servo motor 105 to rotate, thereby driving the rotating worm 104 to rotate, and then driving the rotating worm wheel 102 to rotate, and then driving the two liquid storage bins 2 at the bottom to rotate and swap positions, thereby causing the overflowing liquid storage bin 2 to rotate to the side, and the empty liquid storage bin 2 to rotate to the bottom of the Y-tube 1011 to continue storing liquid.

[0031] In the utility model, during the rotation of the liquid storage bin 2, the switch plate 209 is first slidably connected with the convex plate 1052. During the sliding connection, the switch plate 209 moves toward the inside of the liquid storage bin 2 due to the squeezing effect of the convex plate 1052, thereby causing the sliding rod 208 to move inward, thereby causing the sealing plate 207 to move and break away from the sealed state, thereby causing the liquid inside the liquid storage bin 2 to be discharged through the drain port, drain pipe 211, rotating pipe 212 and conduit 213. The rotating pipe 212 can rotate with the liquid storage bin 2 to avoid the drain pipe 211 from rotating and entangled. After the liquid inside the liquid storage bin 2 is discharged, the liquid storage bin 2 rotates to the position of the compression roller 302.

[0032] In the utility model, when the liquid storage bin 2 rotates to the compression roller 302 position due to the rotation of the rotating worm wheel 102 drives the compression gear 301 to rotate, and then drives the compression roller 302 to rotate, so that the disinfection airbag 206 is compressed by the compression roller 302, so that the disinfection gas inside the disinfection airbag 206 disinfects and cleans the inner wall of the liquid storage bin 2, ensuring that the inside of the liquid storage bin 2 is in a sterilized state. At this time, the switch plate 209 is no longer squeezed by the convex plate 1052, so that the switch plate 209 is reset, and then the sealing plate 207 is reset and the sealing state is restored. At the same time, the liquid in the liquid storage bin 2 is discharged, and the buoyancy block 203 and the trigger 202 return to the initial position. After the disinfection is completed, the liquid storage bin 2 rotates to the previously empty liquid storage bin 2 position and waits for the next use or replacement by medical staff. Here, there is a distance between the rotating worm wheel 102 and the compression gear 301, which does not affect the meshing between the rotating worm 104 and the rotating worm wheel 102.

[0033] In the utility model, when the trigger 202 starts the rotation and switching, the internal controller of the buzzer board 1051 receives and identifies the signal, and then controls the internal buzzer of the buzzer board 1051 to alarm, reminding the medical staff that the liquid storage tank 2 is overflowing. When the overflow reaches a certain number of times, it can be cleaned. Since a drainage pipe 211, a rotating tube 212 and a catheter 213 are provided at the bottom of the liquid storage tank 2, the accumulated liquid can be discharged through the pipe and the sewer. The medical staff can make the ventilator continuously collect the accumulated liquid without replacing the liquid cup, saving a lot of operation time.

[0034] The standard parts used in the utility model can all be purchased from the market, and the special-shaped parts can all be customized according to the description and the drawings.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
