[0029] Example 1

[0030] like Figure 1As shown, this embodiment provides a sample retention bottle 1, including a bottle body 11, a bottle cap 12, and a bottle nozzle 13. The bottle body 11 and the bottle cap 12 are threaded together. The bottle nozzle 13 passes through the bottle cap and is placed inside the bottle body 11. A valve core 14 is provided inside the bottle nozzle 13. The valve core 14 is configured to release the seal inside the bottle nozzle 13 under external force. The bottle nozzle 13 is configured to move away from the bottle cap 12 under external force, thereby releasing the seal between the bottle nozzle 13 and the bottle cap 12. The bottle nozzle 13 is sealed by the valve core 14. When the valve core 14 is pressed downward by external force, it drives the bottle nozzle 13 to move, thereby creating a gap between the bottle cap 12 and the bottle nozzle 13. Air enters the bottle body 11 through the gap. Exhaust and drainage are achieved through only one opening, avoiding water contamination.

[0031] The bottle spout 13 includes a bottle spout body 131 and a funnel-shaped bottom 132. The bottle spout body 131 has a ring of protruding blocks 1311 around its circumference, and the funnel-shaped bottom 132 has an opening.

[0032] A stopper 15 is provided between the bottle body 11 and the bottle cap 12. The stopper 15 is a T-shaped stopper, and the interior of the vertical T-shaped portion 151 of the stopper is a hollow structure 152. The stopper 15 has an opening and is fitted onto the bottle mouth 13, with a protruding block 1311 placed inside the hollow structure 152. A spring 2 is provided inside the hollow structure 152 and is fitted onto the bottle mouth 13.

[0033] A sealing ring 1 3 and a sealing ring 2 4 are provided between the bottle cap 12 and the bottle body 11. The sealing ring 1 3 and the sealing ring 2 4 are respectively located on the upper and lower sides of the T-shaped transverse portion 153 of the bottle stopper. The protruding block 1311 is in contact with the sealing ring 1 under normal conditions, thereby achieving a sealing state between the bottle mouth and the bottle cap. When the valve core 14 is pressed down by an external force, it drives the bottle mouth 13 to move. The protruding block 1311 on the bottle mouth compresses the spring, and the protruding block 1311 moves away from the sealing ring 1 3, so that there is a gap between the bottle mouth and the bottle cap, and air can enter the sample bottle 1 through the gap.

[0034] The bottle body 11 is also provided with a silicone tube 16, and the opening is tightly attached to the inner wall of the silicone tube 16, so that water can enter and exit the sample bottle 1 through the silicone tube 16.

[0035] Example 2

[0036] like Figure 4 As shown, this embodiment provides a sample retention bottle. The difference from embodiment 1 is that the valve core also uses a self-made sealing structure. The sealing structure 14a includes a rubber ball 141a and an elastic element 142a. The rubber ball 141a is used to seal the bottle mouth 13, and the elastic element 142a is used to restore the rubber ball 141a to its original position.

[0037] Example 3

[0038] like Figure 3 As shown, this embodiment provides a water quality sampler inlet and outlet device, including a lifting mechanism 5 and the aforementioned sample bottle 1. The lifting mechanism 5 is configured to push into the bottle nozzle 13 to release the bottle nozzle from its closed state, thereby performing the inlet and outlet operation.

[0039] The lifting mechanism 5 includes a top block 50, a top rod 51, and a sealing ring 52. The top block 50 is located on the outer periphery of the top rod 51. The top block 50 has a sealing groove for placing the sealing ring 52. The cross-section of the top block 50 is a stepped surface, which is used to open the bottle mouth 13. The sealing ring 52 is configured such that when the top rod 51 is pushed into the bottle mouth 13, the sealing ring 52 is tightly attached to the bottle mouth 13, sealing the top rod 51 and the bottle mouth 13.

[0040] The top rod 51 is equipped with an inlet and outlet channel, through which water can enter and exit the sample bottle via the inlet and outlet channel and the silicone tube 16.

[0041] Preferably, the lifting mechanism 5 can be controlled to move by a lifting mechanism or a pneumatic circuit. The lifting mechanism includes an electric push rod or a guide rail slide. The electric push rod or guide rail slide controls the height of movement to ensure that the push rod can be pushed into the sample bottle.

[0042] Preferably, the inlet and outlet device further includes a tray 6, in which the sample bottles 1 are placed in a ring and fitted together. Preferably, the cross-section of the sample bottles 1 is triangular. By fitting the sample bottles 1 in a ring and placing them in the tray 6, more sample bottles 1 can be placed in the same space, which reduces the space required to place the sample bottles 1 and also reduces the overall volume of the water sampler.

[0043] Preferably, the inlet and outlet drainage device further includes a rotary motor 7, which drives the tray 6 to rotate and move the target sample bottle to the lifting mechanism. When a sample bottle needs to be inlet or outlet, the rotary motor 7 can be controlled to rotate and move the target sample bottle to the lifting mechanism 5. The lifting mechanism 5 is inserted into the bottle mouth 13 to perform the inlet and outlet drainage operation.

[0044] Preferably, in order to facilitate smoother rotation of the tray 6, a sliding device 8 can be provided at the bottom of the tray to assist its rotation.

[0045] Preferably, the inlet and outlet drainage device further includes an identification device or a positioning device for identifying or locating the target sample bottle. The identification device includes, but is not limited to, a limit switch and a magnetic encoder.

[0046] like Figure 4As shown, when the top rod is not inserted into the bottle mouth, the sample bottle is in a sealed state. At this time, the valve core is held in place by its own internal spring, and the inside of the bottle mouth is in a closed state. Due to the contact between the protruding block 1311 and the sealing ring, the bottle mouth and the bottle cap are sealed. The bottle mouth and the bottle cap are also in a sealed state, and air and water cannot be poured out of the bottle.

[0047] like Figure 5 As shown, the top block 50 moves the top column nozzle downwards. After the top rod is inserted into the nozzle, the sample bottle enters the water inlet / outlet state. At this time, the valve core inside the nozzle is pushed open downwards by the top rod. Due to the movement of the nozzle, the spring inside the hollow structure is compressed, and there is a gap between the nozzle and the cap. Air enters and exits the sample bottle through the gap between the nozzle and the cap. The top rod is sealed to the inner wall of the nozzle by the sealing ring. Water can enter and exit the sample bottle through the inner hole of the top rod and the silicone tube.
