[0033] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0034] Example 1, as Figures 1-5 As shown, in order to solve the existing problems, this utility model discloses a recyclable sampling device, including a tank 1 and a scale line 2 set on its outer arc surface. A guide groove 3 is provided at the bottom of the inner wall of the tank 1. A sampling tube 4 is connected through the side of the tank 1. One end of the sampling tube 4 is set inside the guide groove 3. The other end of the sampling tube 4 is connected to a control valve 5. A connector 6 is connected to the other side of the control valve 5. A cover plate 7 is connected to the top of the tank 1. An aspiration component 8 is connected to the top of the cover plate 7.

[0035] The suction component 8 includes a suction tube 801 that is connected through the top of the cover plate 7. An electric telescopic rod 802 is connected to the top of the suction tube 801. A pneumatic plate is connected to the bottom telescopic end of the electric telescopic rod 802. The pneumatic plate is slidably connected to the inner wall of the suction tube 801.

[0036] The outer arc surface of the suction tube 801 is connected to a branch tube 803, and the other end of the branch tube 803 is connected to a control housing 804. A rotating shaft 806 is rotatably connected to the side of the control housing 804.

[0037] The outer arc surface of the rotating shaft 806 is connected to a blocking plate 807. One end of the rotating shaft 806 is threadedly connected to a locking knob 809. The outer arc surface of the rotating shaft 806 is rotatably connected to a blocking member 808. The blocking member 808 is provided with a countersunk hole. The inner wall of the countersunk hole is rotatably connected to the rotating shaft 806. The locking knob 809 penetrates the inner wall of the countersunk hole and contacts and presses against the side of the blocking member 808.

[0038] The control housing 804 has a through arc-shaped groove 810 on its side. A transmission rod 811 is slidably connected to the inner wall of the arc-shaped groove 810. The other end of the transmission rod 811 is connected to the side of the baffle plate 807 away from the rotating shaft 806. The side of the transmission rod 811 is in contact with the side of the baffle member 808.

[0039] The specific working principle is as follows: This device can effectively improve the efficiency of sample collection. When in use, the tank 1 and cover plate 7 form a sealed space, thereby achieving the absorption effect. The connector 6 is placed inside the sample, and the control valve 5 is closed. At this time, the inside of the tank 1 is in a sealed state. Then, the electric telescopic rod 802 is activated, which drives the air pressure plate to rise and slide, thereby generating negative pressure inside the tank 1. During the sampling process, the blocking member 808 is set on the side of the transmission rod 811 near the branch pipe 803. At this time, the blocking plate 807 can freely deflect towards the filter screen 805. Thus, when the air pressure plate driven by the electric telescopic rod 802 rises, the inside of the suction pipe 801 is under negative pressure, and the blocking plates 807 are in contact with each other in a sealed state. When the air pressure plate moves downward... During movement, the internal pressure of the suction tube 801 increases, pushing the baffle plate 807 to rotate, thereby expelling excess air from the tank 1 and generating negative pressure. After a period of time, the tank 1 is in a negative pressure environment. Opening the control valve 5 allows external samples to be sucked into the tank 1 of this device. The suction volume can be easily controlled by the scale line 2. When the device needs to discharge the sample, the baffle 808 is moved to the side of the transmission rod 811 away from the branch tube 803 and fixed. At this time, the baffle plate 807 can only tilt and rotate in the direction of the branch tube 803, thereby achieving a one-way air intake effect inside the control housing 804. This, in turn, achieves the effect of adding air and pressurizing the tank 1 through the combination of the electric telescopic rod 802 and the air pressure plate, causing the internal pressure of the tank 1 to rise. At this time, opening the control valve 5 allows the sample to be squeezed out from the sampling tube 4 by air pressure, thereby achieving the discharge effect.

[0040] Example 2, as Figures 1-5 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the first embodiment above, the recyclable sampling device further includes: a filter screen 805 connected to one end of the control housing 804 away from the branch pipe 803; the rotating shaft 806 and the baffle plate 807 are mirror-symmetrically distributed on both sides inside the control housing 804; and the two baffle plates 807 are in contact with each other on the side away from the rotating shaft 806.

[0041] The specific working principle is as follows: This device can generate negative pressure inside the tank 1, thereby achieving the effect of drawing samples from the connector 6, which reduces the difficulty of operating the device. Compared with traditional devices, this device is more compact and highly integrated, which reduces the difficulty of use.

[0042] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
