[0021] The utility model provides Figure 1 , Figure 2 and Figure 4As shown, the negative pressure suction statistical liquid meter includes a device body 1 and a current limiting component 2. The inner wall of the device body 1 is provided with a current limiting component 2 for controlling a liquid outlet switch. The current limiting component 2 includes a limiting wheel 201, a support shaft 202, a movable groove 203, a limiting groove 204 and a drainage tube 205. The middle of the limiting wheel 201 is provided with a support shaft 202, and a movable groove 203 is provided at a position corresponding to the support shaft 202 on the inner wall of the device body 1. A limiting groove 204 is provided at a position corresponding to the inner wall of the device body 1 and the limiting wheel 201. A drainage tube 205 is provided on one side of the outer wall of the limiting wheel 201. The limiting wheel 201 is fixedly connected to the support shaft 202, and the support shaft 202 is slidably connected to the inner wall of the device body 1;

[0022] The operation is as follows: when the liquid needs to be taken out, the staff manually turns the limit wheel 201, at which time the support shaft 202 moves inside the moving groove 203, and the limit wheel 201 moves inside the limit groove 204. As the limit wheel 201 moves downward, the limit wheel 201 releases the pressure on the outer wall of the drainage tube 205, and the liquid flows out through the drainage tube 205. The staff can observe the outflow of the liquid on the inner wall of the liquid storage barrel 3 through the observation window 10. By setting the flow limiting component 2, the staff can manually turn the limit wheel 201 when performing the liquid discharge operation on the negative pressure suction statistical liquid meter, thereby controlling the liquid discharge of the drainage tube 205, which meets the actual use requirements. The operator needs to control the liquid discharge size and the switch, and the operation process is convenient, which is convenient for the staff to use and enhances the practicality of the product.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a liquid storage barrel 3 is provided at the top of the drainage tube 205, and the liquid storage barrel 3 is fixedly connected to the inner wall of the device body 1. An air suction pipe 4 is provided at the top of the liquid storage barrel 3. A negative pressure vacuum pump 5 is provided at one end of the air suction pipe 4 away from the liquid storage barrel 3. The negative pressure vacuum pump 5 is fixedly connected to the inner wall of the device body 1. A support seat 6 is provided at the bottom of the device body 1. A liquid suction pipe 7 is provided on the left side of the air suction pipe 4. The liquid suction pipe 7 is fixedly connected to the liquid storage barrel 3. A limiting rod 8 is provided on the outer wall of the liquid suction pipe 7. The limiting rod 8 is fixedly connected to the outer wall of the device body 1. A protective cover 9 is provided at the bottom of the limiting rod 8. An observation window 10 is provided on the front side of the outer wall of the device body 1.

[0024] The specific operation is as follows. First, when the staff needs to perform negative pressure suction, the pipette 7 is taken out from the protective cover 9 and the limit rod 8, and then inserted into the place where liquid needs to be collected. At this time, the negative pressure vacuum pump 5 is driven to work, and the liquid is subjected to the negative pressure through the pipette 7 to the liquid storage barrel 3. At this time, the staff can observe the amount of liquid taken through the observation window 10. When the liquid collection is completed, the negative pressure vacuum pump 5 is turned off, and the pipette 7 is put back to its original position. By setting the limit rod 8 and the protective cover 9, the staff can limit the pipette 7 after the use of the negative pressure statistical liquid meter is finished. The protective cover 9 can protect the pipette 7. Secondly, the pipe mouth will not be contaminated by dust during the prevention process.

[0025] Working principle of this utility model:

[0026] Refer to the instruction manual Figures 1 to 4 When using the utility model, first when the staff needs to perform negative pressure suction, the pipette 7 is taken out from the protective cover 9 and the limit rod 8, and then inserted into the place where liquid needs to be collected. At this time, the negative pressure vacuum pump 5 is driven to work, and the liquid is received by the negative pressure through the pipette 7 to the liquid storage barrel 3. At this time, the staff can observe the amount of liquid taken through the observation window 10. When the liquid is taken, the negative pressure vacuum pump 5 is turned off and the pipette 7 is put back to its original position. When the liquid needs to be taken out, the staff manually turns the limit wheel 201. At this time, the support shaft 202 moves inside the moving groove 203, and the limit wheel 201 moves inside the limit groove 204. As the limit wheel 201 moves downward, the limit wheel 201 releases the pressure on the outer wall of the drainage tube 205. At this time, the liquid flows out through the drainage tube 205, and the staff observes the outflow of the liquid on the inner wall of the liquid storage barrel 3 through the observation window 10. The above is the working principle.
