[0045] like Figure 1-4 As shown, the utility model provides a tap water sample injection device, including a frame 100, a controller, an operation panel 200, a positioning seat 300, a water tank 400, a water injection component and a detection component.

[0046] The controller is disposed on the frame 100. The operation panel 200 is disposed on the frame 100, and the operation panel 200 is electrically connected to the controller. In one embodiment, the operation panel 200 is a touch screen.

[0047] The positioning seat 300 has a positioning groove. Preferably, a clamping assembly is provided in the positioning groove. The positioning seat 300 is provided on the frame 100, and a plurality of positioning seats 300 are provided, and the plurality of positioning seats 300 are arranged in sequence and spaced apart along the Y-axis direction. In the present embodiment, five positioning seats 300 are provided. The water tank 400 is provided on the frame 100. Preferably, the water tank 400 is detachably connected to the frame 100 so as to facilitate the removal of the water tank 400 for cleaning. Preferably, the number of water tanks 400 is equal to the number of positioning seats 300 and corresponds one to one, so as to achieve the purpose of adding different sample waters to different sampling tubes 800 at the same time.

[0048] The water injection assembly is disposed on the frame 100 and is used to inject a preset amount of sample water into the target sampling tube 800. Specifically, the water injection assembly includes a water injection pipe 510, a water outlet pipe 520, a flow sensor 530 and a water pump 540.

[0049] The water injection pipe 510 is arranged on the frame 100 and is located above the positioning seat 300. The number of the water injection pipes 510 is equal to the number of the positioning seat 300 and corresponds one to one. The number of the water outlet pipes 520 is equal to the number of the water injection pipes 510 and corresponds one to one. The liquid inlet end of the water outlet pipe 520 is connected to the water tank 400, and the liquid outlet end is connected to the liquid inlet end of the water injection pipe 510. The flow sensor 530 is arranged on the water injection pipe 510 or the water outlet pipe 520, and the flow sensor 530 is electrically connected to the controller. The water pump 540 is arranged on the water injection pipe 510 or the water outlet pipe 520, and the water pump 540 is electrically connected to the controller. Preferably, the water injection assembly also includes a control valve 550, the number of the control valve 550 is equal to the number of the water injection pipes 510 and corresponds one to one, the control valve 550 is arranged on the water injection pipe 510 or the water outlet pipe 520, and the control valve 550 is electrically connected to the controller.

[0050] The detection component is disposed on the frame 100, and the detection component is electrically connected to the controller, and the detection component is used to detect whether a sampling bottle is placed in the target positioning seat 300. When in use, if the detection component detects that no sampling bottle is placed in the target positioning seat 300, the controller controls the water pump 540 corresponding to the target positioning seat 300 to remain closed; if the detection component detects that a sampling bottle is placed in the target positioning seat 300, the controller controls the water pump 540 corresponding to the target positioning seat 300 to be turned on, thereby injecting sample water into the target sampling tube 800.

[0051] Specifically, when in use, first place the sampling tube 800 into the positioning seat 300; then set the volume of sample water to be injected through the operation panel 200; thereafter, the controller controls the corresponding water pump 540 to turn on according to the information detected by the detection component, thereby injecting a preset amount of sample water into the sampling tube 800. When the flow sensor 530 detects that the volume of the injected sample water reaches the preset amount, the water pump 540 is controlled to be closed through the controller, thereby achieving the purpose of automatically injecting the preset amount of sample water.

[0052] Of course, in this embodiment, through the setting of the operation panel 200, not only can the same volume of sample water be injected into each sampling tube 800, but different volumes of sample water can also be injected into each sampling tube 800 according to actual needs.

[0053] In one embodiment, it further includes a moving base 610 and a first driving assembly.

[0054] The movable seat 610 is slidably disposed on the frame 100, and the movable seat 610 can reciprocate linearly between the first position and the second position along the X-axis direction. The first driving component is disposed on the frame 100, and the first driving component is used to drive the movable seat 610 to reciprocate linearly between the first position and the second position.

[0055] Among them, the positioning seat 300 is fixedly set on the movable seat 610, and when the movable seat 610 is in the first position, the positioning seat 300 is located directly below the water injection pipe 510, and when the movable seat 610 is in the second position, the positioning seat 300 is located below the front side of the water injection pipe 510.

[0056] During water injection, the distance between the water injection pipe 510 and the sampling pipe 800 should not be too large to avoid splashing of the sample water. Therefore, in this embodiment, by providing the movable seat 610 and the first driving assembly, when taking and placing the sampling pipe 800, the first driving assembly drives the movable seat 610 to the second position, so as to achieve the purpose of not touching the water injection pipe 510 during the process of taking and placing the sampling pipe 800. During water injection, the first driving assembly drives the movable seat 610 to the first position, so as to achieve the purpose of normal water injection.

[0057] In this embodiment, by setting up a movable seat 610 and a first driving assembly, the sampling tube 800 is located at the front side of the water injection pipe 510 during the process of taking and placing the sampling tube 800. This can not only achieve the purpose of minimizing the water injection height of the water injection pipe 510, but also achieve the purpose of avoiding the possibility of collision between the sampling tube 800 and the main water pipe during the process of taking and placing the sampling tube 800.

[0058] In one embodiment, the first driving assembly includes a first screw 620 and a first power device 630 .

Specifically, the first power device can be a motor, a driving handle, a driving handle, etc. In the present embodiment, the first power device 630 is a servo motor, and the servo motor is electrically connected to the controller.

[0060] When in use, the first power device 630 drives the first screw rod 620 to rotate, thereby driving the movable seat 610 to perform reciprocating linear motion between the first position and the second position through the first screw rod 620. Specifically, when the first power device 630 drives the first screw rod 620 to rotate forward, the movable seat 610 moves from the first position to the second position, and when the first power device 630 drives the first screw rod 620 to rotate reversely, the movable seat 610 moves from the second position to the first position.

[0061] In this embodiment, the first driving assembly provided has a simple structure, reasonable design and convenient operation.

The second driving assembly is disposed on the frame 100, and the second driving assembly is used to drive the lifting seat 710 to perform reciprocating linear motion between the third position and the fourth position.

[0064] Since different sampling tubes 800 have different heights, in this embodiment, the lifting seat 710 and the second driving assembly are provided so as to achieve the purpose of adjusting the height of the water injection tube 510 according to the sampling tubes 800 of different heights.

[0065] Preferably, the water tank 400 is disposed on the lifting seat 710 to shorten the water outlet pipe 520 .

The second power device 730 is arranged on the frame 100, and the second power device 730 is transmission-connected to the second lead screw 720. Specifically, the second power device 730 can be a motor, a driving handle, etc. In this embodiment, the second power device 730 is a driving handle, the driving handle is sleeved on the top of the second lead screw 720, and the second power device 730 is fixedly connected to the second lead screw 720.

[0068] When in use, the second screw 720 is rotated by the second power device 730 to adjust the height of the lifting seat 710. Specifically, when the second power device 730 is rotated forward, the lifting seat 710 moves from the third position to the fourth position, and when the second power device 730 is rotated backward, the lifting seat 710 moves from the fourth position to the third position.

[0069] In one embodiment, the detection assembly includes pressure sensors, the number of which is equal to and corresponds to the number of the positioning seats 300, and the pressure sensors are fixedly arranged at the bottom of the positioning seat 300. When in use, after the sampling tube 800 is placed in the positioning groove, under the action of its own gravity, the sampling tube 800 will apply a pressure to the pressure sensor, thereby achieving the purpose of detecting whether the sampling tube 800 is placed in the positioning seat 300.
