[0030] Next, in combination with the attached drawings, the embodiments of the present utility model will be introduced in detail.

[0031] Refer to Figures 1 - 6 , the present utility model provides a dissolved oxygen detection bottle, which includes a bottle body 1 and a bottle stopper 2.

[0032] In this application, the bottle body 1 is made of glass, that is, the bottle body 1 is a glass bottle. A bottle cavity 10 is formed inside the bottle body 1. The upper end of the bottle cavity 10 is open (has an opening) for containing the liquid to be detected. The open end of the bottle cavity 10 extends upward to form a bottleneck 11. In this embodiment, the inner wall of the bottleneck 11 is an inclined surface, forming a tapered structure with a larger upper end and a smaller lower end, which facilitates the installation of the bottle stopper 2. Preferably, the angle between the inner wall of the bottleneck and the axis of the bottleneck is 2 - 5 degrees. The end of the bottleneck 11 flares upward (increases in diameter) to form a bottle mouth 12. In this embodiment, the end of the bottleneck 11 extends upward obliquely to form the bottle mouth 12. The bottle mouth 12 as a whole forms a conical structure with a larger upper end and a smaller lower end. The angle between the bottle mouth 12 and the axis of the bottle body is 25 - 45 degrees, preferably 30 - 33 degrees, which is used for liquid sealing.

[0033] The bottle stopper 2 as a whole is a cylindrical structure, which can be inserted into the bottleneck 11 to seal the bottle cavity. In this embodiment, the side wall of the bottle stopper 2 is also an inclined surface, which has the same slope as the bottleneck and can fit against the inner wall of the bottleneck. At the same time, it can achieve axial precision positioning. When the bottle stopper 2 is inserted into the bottleneck and sealed, the top of the bottle stopper 2 is higher than the top of the bottle mouth 12, that is, the top surface of the bottle stopper 2 is located above the top surface 12a of the bottle mouth 12. A liquid sealing area is formed between the outer wall of the bottle stopper 2 and the inner wall of the bottle mouth 12, which can accommodate the liquid sealing liquid. A liquid adding hole 202 is opened at the top of the bottle stopper 2. At the same time, a liquid discharging hole 203 is opened on the side wall of the bottle stopper 2. The liquid discharging hole 203 is communicated with the liquid adding hole 202. The liquid discharging hole 203 is located in the liquid sealing area. When the liquid sealing liquid enters from the liquid adding hole 202, it is discharged through the liquid discharging hole 203, so that the liquid sealing liquid enters the liquid sealing area, and then the bottle body is liquid-sealed (liquid is sealed), which can effectively prevent air from entering the bottle and improve the detection accuracy and reliability. In order to facilitate the addition of the liquid sealing solution, in this embodiment, a counterbore is provided at the top of the bottle stopper 2 to form a liquid adding port 201. The side wall of the liquid adding port 201 is an inclined surface, forming a funnel structure, which increases the diameter of the liquid addition and facilitates the addition of the sealing liquid. The liquid adding hole 202 is opened at the bottom surface of the liquid adding port 201.

[0034] When the opening detection is required, the liquid sealing liquid in the liquid sealing area needs to be drained first to avoid entering the bottle cavity during opening. Therefore, before opening the cap, a liquid extraction needle needs to be inserted into the liquid adding hole first, and the liquid sealing solution is extracted by negative pressure. Therefore, the liquid adding hole 202 is a linear hole, which is vertically arranged and can accommodate the liquid extraction needle to insert, so as to realize the liquid sealing drainage (liquid extraction). In this embodiment, the axis of the liquid adding hole is coaxial with the bottle stopper, that is, located at the center, which is convenient for the quick and accurate positioning of the liquid extraction needle; at the same time, the liquid outlet hole 203 is located at the lower end of the liquid sealing area, which can allow the liquid sealing liquid in the liquid sealing area to completely enter the liquid outlet hole 203 for drainage during liquid extraction, avoiding the accumulation of liquid in the liquid sealing area from flowing into the bottle; specifically, an annular protrusion is provided on the side wall of the bottle stopper 2, and the annular protrusion forms a sealing portion 22 for contacting the inner wall of the bottleneck to achieve sealing. The sealing portion 22 is one or more, preferably two or more, which are arranged in sequence from top to bottom. The liquid outlet hole 203 is flush with the uppermost sealing portion 22. Therefore, during liquid extraction, all the liquid in the liquid sealing area can enter the liquid outlet hole, improving the drainage (liquid extraction) effect.

[0035] In this embodiment, the top of the bottle stopper 2 extends radially outward to form a clamping portion 21, and a part of the liquid adding port extends to the clamping portion, thereby increasing the diameter of the liquid adding port and improving the liquid adding efficiency; at the same time, the bottom surface of the clamping portion 21 is an inclined surface, which forms a first inclined guide surface 21a, and its inner side is inclined downward to form a tapered structure with thin sides and thick middle. When the bottle stopper is sealed and installed, there is a spacing between the first inclined guide surface 21a and the top surface 12a of the bottle mouth 12, forming a clamping area for opening the cap and clamping.

[0036] Refer to Figures 7 - 10, Meanwhile, the present utility model also provides an opening device for a dissolved oxygen detection bottle, which is used to remove the bottle stopper 2 of the dissolved oxygen detection bottle without generating an upward pulling force on the bottle body. Specifically, it includes a moving robotic arm (not shown in the figure). A clamping cylinder 4 is fixed at the lower end of the robotic arm. The clamping cylinder 4 is vertically arranged, and its output end is located at the lower end. There are at least two output ends, and it can perform clamping (moving closer to each other) or loosening (moving away from each other) actions. In this application, the clamping cylinder 4 is not a finger cylinder and has two output ends. A claw 3 is fixed at the output end of the clamping cylinder 4. A protrusion is provided on the inner wall (towards the bottle stopper end) of the claw 3 to form a clamping block 31. The inner wall of the clamping block 31 is an arc surface, and the upper surface of the clamping block 31 is an inclined surface to form a second inclined guide surface 31a. The inclination direction and inclination angle of the second inclined guide surface 31a are the same as those of the first inclined guide surface (at the lower end of the clamping part of the bottle stopper 2). Therefore, it can be in fitting contact with the first inclined guide surface. A support surface 31b is provided on the bottom surface of the claw 3. In this embodiment, the support surface 31b is a plane, which can contact the top of the bottle mouth of the bottle body 1 to support the bottle body, avoiding pulling the bottle body upward during the opening process, resulting in impact, vibration, or even tipping of the bottle body. The thickness inside the clamping block 31 is slightly smaller than the distance outside the clamping area (there is a spacing between the first inclined guide surface 21a and the top surface 12a of the bottle mouth 12). During opening, the bottom surface (support surface) of the clamping block 31 is slightly higher than the height of the bottle mouth of the bottle body, and then it is clamped inward. During the inward movement of the clamping block, the second inclined guide surface 31a on the top surface of the clamping block contacts the first inclined guide surface at the lower end of the bottle stopper, and the bottle stopper moves upward as the clamping block moves inward. At the same time, the bottle body will move upward under the frictional force of the bottle stopper. At this time, the bottom surface of the clamping block contacts the top of the bottle mouth, restricting the upward movement of the bottle body, while the bottle stopper is still in the upward movement process and is finally pulled out from the bottleneck, completing the opening of the bottle.

[0037] For the dissolved oxygen detection bottle of the present utility model, a liquid seal area is set, which can perform liquid sealing on the bottle body, greatly improving its sealing performance, preventing air from entering, and improving the detection accuracy and quality; a liquid adding hole is set, which can add liquid to the liquid seal area, making the liquid adding convenient without splashing, clean and hygienic; a conical liquid adding port is set to form a funnel structure, facilitating liquid adding, improving the liquid adding accuracy and efficiency, and thus improving the detection efficiency; the liquid outlet hole is arranged at the lower end of the liquid seal area, which can ensure that the liquid in the liquid seal area is completely discharged during the opening and liquid extraction process, avoiding flowing into the bottle during opening and causing interference, and improving the detection accuracy; a first inclined guide surface is set on the bottle stopper, which cooperates with the second inclined guide surface of the claw to pull out the bottle stopper by extrusion, avoiding pulling up the bottle body and causing impact, vibration, or even tipping of the bottle body, greatly improving the reliability and stability of the bottle body opening; the dissolved oxygen detection bottle of the present utility model has a compact structure, convenient operation, strong sealing performance, and good use effect.

[0038] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
