[0039] See also Figure 1-6A specimen liquid storage tank 1 in one embodiment of the present invention includes a tank body 11 for storing specimen liquid, a cover body 12, a sealing cover 13 and an elastic reset member 134. The tank body 11 is provided with a tank opening 111, and the cover body 12 covers the tank opening 111. The cover body 12 is provided with an opening 1224 for connecting the inside and outside of the tank body 11 for allowing the specimen liquid in the tank body 11 to flow out. The sealing cover 13 and the cover body 12 are independent of each other, that is, the sealing cover 13 and the cover body 12 are not integrally formed. The sealing cover 13 is provided on the cover body 12 and seals the opening 1224. The sealing cover 13 can be separated from the cover body 12 and matched with the cover body 12 toward the inside of the tank body 11.

[0040] The sealing cover 13 of the specimen liquid storage tank 1 and the opening 1224 of the cover body 12 form a seal, thereby preventing the specimen liquid in the storage tank from leaking out. When the specimen liquid is needed, the sealing cover 13 can be pressed and pushed into the neck 112 or the tank body 11 to open the opening 1224, and the specimen liquid is taken through the opening 1224. For example, the method of taking the specimen liquid through the liquid collection instrument 2 can be as follows: a protrusion 212 is provided on the liquid collection instrument 2, and the protrusion 212 is aligned with the sealing cover 13 and pushes the sealing cover 13 open, and the specimen liquid flows out through the opening 1224 and flows into the liquid collection instrument 2, and then the user can take the specimen liquid through the liquid collection instrument 2.

[0041] The specimen liquid storage tank 1 is sealed by the cooperation between the sealing cover 13 and the cover body 12, and the opening 1224 can be conveniently opened when the specimen liquid is needed.

[0042] See also Figure 4-6 In the first embodiment, the sealing cover 13 includes a covering portion 131, an extending portion 132, and a sealing member 133. The covering portion 131 is provided in the tank opening 111, located on the inner side of the cover body 12 and corresponding to the opening 1224. The sealing member 133 is provided on the covering portion 131, located outside the opening 1224 and used to seal the opening 1224. The extending portion 132 is connected to the covering portion 131 and can be extended and retracted through the cover body 12. The elastic return member 134 connects the sealing cover 13 and the cover body 12. The sealing cover 13 can be movably provided on the cover body 12 between a closed state and an open state.

[0043] The closed state is: under the elastic force of the elastic return member 134, the protruding portion 132 protrudes outward (that is, the protruding portion 132 moves in the direction away from the tank body 11), the covering portion 131 covers the opening 1224 and the sealing member 133 contacts the cover body 12 to seal the opening 1224; the open state is: the protruding portion 132 is acted upon by an external force to overcome the force of the elastic return member 134 and retract inward, that is, the protruding portion 132 moves in the direction close to the tank body 11, the covering portion 131 leaves the opening 1224 and the sealing member 133 leaves the cover body 12 to open the opening 1224.

[0044] When there is no need to take out the specimen liquid from the specimen liquid storage tank 1, the protruding portion 132 of the sealing cover 13 is not subjected to external force. Under the elastic force of the elastic reset member 134, the protruding portion 132 extends outward, the covering portion 131 covers the opening 1224 of the cover body 12, and the sealing member 133 contacts the cover body 12 to form a seal at the opening 1224. The sealing cover 13 is in a closed state, and the specimen liquid in the tank body 11 cannot flow out through the opening 1224. When the specimen liquid needs to be taken out of the specimen liquid storage tank 1, the extension portion 132 is retracted inward by external force (i.e., the extension portion 132 is moved toward the interior of the tank body 11). For example, when the specimen liquid storage tank 1 is installed on the specimen liquid collection instrument 2, the specimen liquid collection instrument 2 pushes the extension portion 132 inward, so that the covering portion 131 leaves the opening 1224 of the cover body 12, the sealing member 133 leaves the cover body 12, the seal of the opening 1224 is released, and the specimen liquid in the tank body 11 can flow outward through the opening 1224.

[0045] The specimen liquid storage tank 1 is sealed by the cooperation between the sealing cover 13 and the cover body 12 , and can be opened conveniently when the specimen liquid needs to be taken out.

[0046] The cover body 12 includes a base 121 arranged at the tank mouth 111 and an inner recess 122 arranged on the base 121, the inner recess 122 includes a first end wall 1222 and a first side wall 1221 arranged outside the first end wall 1222, the first end wall 1222 and the first side wall 1221 define a concave cavity 1223 open to the outside, and an opening 1224 is provided on the first side wall 1221; the sealing cover 13 includes a second end wall 1312 corresponding to the first end wall 1222 and a second side wall 1311 corresponding to the first side wall 1221.

[0047] The protruding portion 132 is connected to the second end wall 1312 , passes through the first end wall 1222 and protrudes outward, with the protruding portion being located in the concave cavity 1223 .

[0048] The extending portion 132 is rod-shaped, and the elastic return member 134 is a spring and is sleeved on the extending portion 132 .

[0049] The sealing member 133 is provided on the second side wall 1311 . The sealing member 133 is preferably a sealing ring and is sleeved on the second side wall 1311 .

[0050] A groove 123 corresponding to the second side wall 1311 surrounding the inner recess 122 is defined between the first side wall 1221 of the inner recess 122 and the cover body 12. When the sealing cover 13 is in the closed state, the second side wall 1311 extends into the groove 123 and the sealing member 133 cooperates with the inner wall of the groove 123 to form a seal for the opening 1224; when the sealing cover 13 is in the open state, the second side wall 1311 leaves the groove 123 and the sealing member 133 separates from the inner wall of the groove 123, and the seal of the opening 1224 is released.

[0051] See also Figure 7-9 In the second embodiment, the cover body 12 includes a base plate 31 and a protruding structure 32 provided on the base plate 31, the opening 1224 is provided on the base plate 31, the protruding structure 32 extends along the edge of the opening 1224, the protruding structure 32 protrudes toward the tank body 11 and the center of the opening 1224 to form a step-like structure, the sealing cover 13 includes a main body 51 and a first extension portion 52 and a second extension portion 53 provided on the main body 51, the main body 51 is provided in the opening 1224, the first extension portion 52 covers the surface of the protruding structure 32 facing away from the tank body 11 from the edge of the base 121, the second extension portion 53 covers the surface of the protruding structure 32 facing the tank body 11 and the surface facing away from the opening 1224, the protruding structure 32 is between the first extension portion 52 and the second extension portion 53, such a structure enables the sealing cover 13 to withstand the pressure of the specimen liquid inside the storage tank while the user can easily push open the sealing cover 13 from the outside.

[0052] On the surface of the cover body 12 facing away from the tank body 11, the raised structure 32 forms a first step 33 that is recessed toward the tank body 11, and the first extension portion 52 covers the first step 33; on the surface of the cover body 12 facing the tank body 11, the raised structure 32 forms a second step 34 that is raised toward the tank body 11, and the second extension portion 53 covers the second step 34.

[0053] The sealing cover 13 is in sheet shape so that when the sealing cover 13 is pressed, the sealing cover 13 is elastically deformed and pushed open. The sealing cover 13 is a rubber plug.

[0054] See also Figure 10-17 A specimen liquid taking device according to one embodiment of the present invention includes a liquid taking instrument 2 and the above-mentioned specimen liquid storage tank 1 which is detachably mounted on the liquid taking instrument 2, so that the specimen liquid in the specimen liquid storage tank 1 can be taken through the liquid taking instrument 2. The liquid taking instrument 2 includes a frame 21 and a liquid taking unit 22 for taking the specimen liquid in the specimen liquid storage tank 1, which is mounted on the frame 21. The frame 21 is provided with a mounting position 211 for mounting the tank mouth 111 of the specimen liquid storage tank 1, a protrusion 212 disposed in the mounting position 211 for pushing the sealing cover 13 toward the tank body 11, and a receiving port 213 disposed in the mounting position 211 for receiving the specimen liquid and leading to the liquid taking unit 22.

[0055] Specifically, in the first embodiment mentioned above, the extension portion 132 of the liquid collection instrument 2 pushes the extension portion 132 of the sealing cover 13 to retract, so that the opening 1224 is opened; in the second embodiment mentioned above, the extension portion 132 of the liquid collection instrument 2 pushes the sealing cover 13 to separate from the cover body 12, so that the opening 1224 is opened.

[0056] When the specimen liquid storage tank 1 is placed on the liquid collecting instrument 2, with the tank mouth 111 installed in the mounting position 211, the protrusion 212 corresponds to the protruding portion 132 of the sealing cover 13 and pushes the protruding portion 132 of the sealing cover 13 to retract, releasing the seal of the opening 1224 of the cover body 12. The specimen liquid in the specimen liquid storage tank 1 flows out into the liquid collecting instrument 2 through the opening 1224, and flows to the liquid collecting unit 22 through the receiving port 213. The user can take the specimen liquid through the liquid collecting unit 22.

[0057] The specimen liquid taking device can conveniently take the specimen liquid in the specimen liquid storage tank 1 by cooperating with the liquid taking instrument 2 and the specimen liquid storage tank 1 .

[0058] A liquid collection chamber 214 open to the outside is provided on one side of the frame 21. The liquid collection instrument 2 includes a movable door 23 that can be movably arranged on the frame 21 longitudinally. The movable door 23 can be movably set between a position covering the open opening of the liquid collection chamber 214 and a position exposing the open opening of the liquid collection chamber 214. The liquid collection unit 22 includes a liquid collection tube 221 for circulating the specimen liquid, a liquid collection head 222 connected to the liquid collection tube 221 for allowing the specimen liquid to flow out, and a switch handle 223 for controlling the outflow of liquid provided on the liquid collection head 222. The liquid collection head 222 and the switch handle 223 are provided on the upper side of the liquid collection chamber 214. The switch handle 223 can be swung longitudinally, and its lower end is exposed in the liquid collection chamber 214. When the movable door 23 covers the open opening of the liquid collection chamber 214, the switch handle 223 is covered by the movable door 23. When liquid collection is not required, the movable door 23 covers the open mouth of the liquid collection chamber 214, the liquid collection head 222 and the switch handle 223; when liquid collection is required, the movable door 23 moves upward to expose the open mouth of the liquid collection chamber 214, allowing the user to place the liquid container into the liquid collection chamber 214 and align it with the liquid collection head 222, control the switch handle 223, and load the specimen liquid through the liquid collection head 222.

[0059] The specimen liquid storage tank 1 includes a neck portion 112 disposed on the tank body 11, a tank opening 111, and a cover 12 disposed on the neck portion 112. A mounting position 211 is recessed to accommodate the neck portion 112. A protruding latch 2111 is disposed on the inner side of the mounting position 211, and a latching groove 124 corresponding to the latch 2111 is disposed on the outer side of the cover 12 or the neck portion 112. When the neck portion 112 is placed in the mounting position 211, the latch 2111 engages the latching groove 124. Because the specimen liquid storage tank 1 becomes lighter when empty of liquid, the latch 2111 and the latching groove 124 prevent the specimen liquid storage tank 1 from automatically floating, thereby preventing volatile gases such as formaldehyde contained therein from escaping into the air.

[0060] The liquid outlet nozzle is detachably connected to the liquid collection pipe 221 , so that the liquid outlet nozzle can be replaced after being damaged, or replaced with a liquid outlet nozzle of different specifications.

[0061] The liquid collection instrument 2 includes a recovery unit 24 for recovering the specimen liquid, which is arranged on the frame 21. The recovery unit 24 includes a recovery interface 241 for receiving the specimen liquid, which is communicated with the lower side of the liquid collection chamber 214, a recovery tube 242 with one end communicated with the recovery interface 241, and a recovery container 243 for accommodating the recovered specimen liquid, which is communicated with the other end of the recovery tube 242. The recovery tube 242 and the recovery container 243 are arranged below the liquid collection chamber 214; because a small amount of specimen liquid will inevitably run out of the liquid collection container when the specimen liquid is loaded and accumulate at the bottom of the liquid collection chamber 214, these specimen liquids can flow back to the recovery container 243 through the recovery interface 241 and the recovery tube 242, and the recovered specimen liquid can be reused to avoid waste. At the same time, it also prevents the specimen liquid from accumulating at the bottom of the liquid collection chamber 214 and volatilizing to produce irritating gas, affecting the user experience or even irritating the human body;

[0062] The recovery tube 242 is rotatably connected to the recovery interface 241 and the recovery container 243, so that when the recovery interface 241 and the recovery container 243 are connected, the recovery tube 242 can also rotate to facilitate adjustment of the recovery tube 242 when the recovery tube 242 is twisted; and / or, the recovery tube 242 is a hose, and the recovery unit 24 includes a control clip 244 clamped on the recovery tube 242 for controlling the on and off of the recovery tube 242. When the control clip 244 is clamped on the recovery tube 242, the clip flattens the recovery tube 242, so that the internal pipeline of the recovery tube 242 is disconnected, and when the control clip 244 is released from the recovery tube 242, the flattened part of the recovery tube 242 is restored and the internal pipeline is opened; and / or, the frame 21 is provided with a accommodating chamber 215 located below the liquid collection chamber 214, the recovery container 243 and the recovery tube 242 are arranged in the accommodating chamber 215, and the bottom of the accommodating chamber 215 is provided with an upwardly open recovery groove 216, the recovery container 243 is arranged in the recovery groove 216, and the bottom of the recovery groove 216 is provided with a drain port 217 for discharging liquid to the outside of the frame 21, and the recovery unit 24 includes a closure member 245 detachably provided on the drain port 217 for closing the drain port 217, and the closure member 245 can be a plug or a cover.

[0063] In summary, when the specimen liquid storage tank 1 of the present invention does not need to be taken out, the extension 132 of the sealing cover 13 is not subjected to external force, and under the elastic force of the elastic reset member 134, a seal is formed at the opening 1224, and the sealing cover 13 is in a closed state. The specimen liquid in the tank body 11 cannot flow out through the opening 1224. When the specimen liquid storage tank 1 needs to be taken out, the extension 132 is retracted inward by external force, the seal of the opening 1224 is released, and the specimen liquid in the tank body 11 can flow out through the opening 1224. The specimen liquid collection device of the present invention includes a liquid collection instrument 2 and the above-mentioned specimen liquid storage tank 1. When the specimen liquid storage tank 1 is placed on the liquid collection instrument 2, the liquid collection instrument 2 can release the seal of the opening 1224 of the cover body 12, and the user can take the specimen liquid through the liquid collection unit 22.
