Abstract
Description
Technical Field
[0001] The utility model relates to the field of oral liquid production, in particular to a sampling device for oral solution detection. Background Art
[0002] In the production process of oral liquid, in order to ensure the quality of the products leaving the factory, it is often necessary to sample and test the oral liquid produced. The general sampling test is to randomly take out several bottles of solution from the production line, and then extract the solution in the solution bottle for testing. The existing solution extraction is generally done manually. During the extraction process, the extraction needle is easy to contact with the bottle mouth, and the extraction needle is in contact with the outside world, which makes the extracted solution easy to be contaminated, resulting in the test results being affected. Utility Model Content
[0003] The utility model aims to solve the above technical problems and provide a sampling device for oral solution detection which can avoid the contact between the movable needle and the solution bottle mouth and can isolate the movable needle from the outside world to avoid external factors affecting the detection results.
[0004] The technical solution is: a sampling device for oral solution detection, including a shell, a piston cylinder is clamped on the shell, a piston rod is slidably connected to the piston cylinder, a movable needle is slidably connected to the shell, a connecting hose is connected between the movable needle and the piston cylinder, a pressing component and a closing component are provided in the shell, the pressing component is used to drive the movable needle to extend into the solution bottle, which can prevent the movable needle from contacting the solution bottle mouth and improve the detection accuracy, and the closing component is used to isolate the movable needle from the outside world to prevent external factors from affecting the detection results and further improve the detection accuracy.
[0005] As a further preferred embodiment, the pressing component includes a pressure rod, which is slidably connected to the shell, the pressure rod and the movable needle are fixedly connected, a pressure spring is connected between the pressure rod and the shell, and a limiting ring is fixedly connected to the shell.
[0006] As a further preferred embodiment, the closing component includes a push rod, the push rod is slidably connected to the movable needle, a reset spring 1 is connected between the push rod and the movable needle, a baffle is slidably connected in the outer shell, and a reset spring 2 is connected between the baffle and the outer shell.
[0007] As a further preferred solution, the connecting hose is retractable to facilitate the movement of the movable needle.
[0008] As a further preferred solution, the limiting ring is made of rubber material to better fit the solution bottle.
[0009] The utility model has the following advantages: 1. The descending of the pressure rod will drive the movable needle to descend, and the pressure spring is compressed. When the movable needle descends into the solution bottle, the detection personnel pulls the piston rod, and the piston rod moves to draw the solution in the solution bottle into the piston cylinder through the connecting hose. In this way, the movable needle can avoid contact with the solution bottle mouth when descending, preventing the solution from being contaminated and improving the detection accuracy.
[0010] 2. The descent of the movable needle will drive the ejector rod to descend, and the descent of the ejector rod will squeeze the baffle plate, causing the baffle plate to move toward the ejector rod, and the reset spring 2 will be compressed. When the bottom of the ejector rod contacts the outer shell, the ejector rod will no longer descend, and the ejector rod will extend into the movable needle, and the reset spring 1 will be compressed. At this time, the baffle plate will no longer isolate the movable needle from the outside world. In this way, the movable needle can be isolated from the outside world, preventing external factors from affecting the test results and further improving the test accuracy.

DETAILED DESCRIPTION
[0017] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.
[0018] Example 1: A sampling device for oral solution detection, such as Figure 1-Figure 5As shown, it includes a shell 1, a piston cylinder 2 is clamped on the shell 1, a piston rod 3 is slidably connected to the piston cylinder 2, a movable needle 4 is slidably connected to the shell 1, a connecting hose 5 is connected between the movable needle 4 and the piston cylinder 2, and a pressing component and a closing component are provided in the shell 1. The pressing component is used to drive the movable needle 4 to extend into the solution bottle, which can prevent the movable needle 4 from contacting the solution bottle mouth and improve the detection accuracy. The closing component is used to isolate the movable needle 4 from the outside world to prevent external factors from affecting the detection results and further improve the detection accuracy.
[0019] The pressing component includes a pressure rod 6, which is slidably connected to the shell 1, and the pressure rod 6 and the movable needle 4 are fixedly connected. A pressure spring 7 is connected between the pressure rod 6 and the shell 1, and a limit ring 8 is fixedly connected to the shell 1. The descent of the pressure rod 6 will drive the movable needle 4 to descend, so that the movable needle 4 extends into the solution bottle, which can prevent the movable needle 4 from contacting the solution bottle mouth, prevent the solution from being contaminated, and improve the detection accuracy.
[0020] At first, the piston cylinder 2 is buckled on the outer shell 1, and the inspector first extends the solution bottle to be tested into the outer shell 1. When the mouth of the solution bottle contacts the limit ring 8, the inspector stops moving the solution bottle. Then, the inspector presses down the pressure rod 6. The descent of the pressure rod 6 will drive the movable needle 4 to descend, and the pressure spring 7 is compressed. When the movable needle 4 descends into the solution bottle, the inspector pulls the piston rod 3, and the piston rod 3 moves through the connecting hose 5 to draw the solution in the solution bottle into the piston cylinder 2. After the sampling is completed, the inspector no longer presses the pressure rod 6, and the pressure spring 7 resets to drive the movable needle 4 to reset, so that the movable needle 4 is separated from the solution bottle. Then the inspector takes out the piston cylinder 2 to complete the sampling. In this way, the movable needle 4 can avoid contact with the mouth of the solution bottle when it descends, thereby preventing the solution from being contaminated and improving the detection accuracy.
[0021] Embodiment 2: Based on embodiment 1, Figure 2-Figure 5 As shown, the closing component includes a push rod 9, the push rod 9 is slidably connected to the movable needle 4, a return spring 10 is connected between the push rod 9 and the movable needle 4, a baffle 11 is slidably connected in the outer shell 1, and a return spring 2 12 is connected between the baffle 11 and the outer shell 1. The descent of the push rod 9 will drive the baffle 11 to move, so that the baffle 11 no longer isolates the movable needle 4 from the outside world for solution extraction, and can isolate the movable needle 4 from the outside world, avoid external factors from affecting the detection results, and further improve the detection accuracy.
[0022] The connecting hose 5 is retractable to facilitate the movement of the movable needle 4 .
[0023] The limiting ring 8 is made of rubber material to better fit the solution bottle.
[0024] At first, the baffle 11 is located below the movable needle 4, and the baffle 11 isolates the movable needle 4 from the outside world. The descent of the movable needle 4 will drive the push rod 9 to descend, and the descent of the push rod 9 will squeeze the baffle 11, so that the baffle 11 moves toward the direction close to the push rod 9, and the reset spring 12 is compressed. When the bottom of the push rod 9 contacts the outer shell 1, the push rod 9 no longer descends, and the push rod 9 will extend into the movable needle 4. The reset spring 10 is compressed. At this time, the baffle 11 no longer isolates the movable needle 4 from the outside world. When the movable needle 4 is reset, the movable needle 4 drives the pressure rod 6 to reset, and the pressure rod 6 resets and no longer squeezes the baffle 11. The reset spring 12 is reset to reset the baffle 11. In this way, the movable needle 4 can be isolated from the outside world, avoiding external factors from affecting the detection results, and further improving the detection accuracy.
