Description

Technical Field

[0001] This utility model relates to the field of chemical apparatus technology, and in particular to a sampling device for chemical analysis and detection. Background Technology

[0002] Chemical apparatus refers to the instruments used in chemical experiments. Commonly used modern experimental instruments include test tubes, beakers, evaporating dishes, crucibles, alcohol lamps, Buchner funnels, and gas washing bottles.

[0003] Currently, in the chemical analysis and testing process, in addition to the aforementioned experimental instruments, sampling devices are also used. However, the sampling device requires the staff to pinch the tail of the device to draw up the chemical test liquid. In the process of multiple comparative tests, this is not conducive to the staff to quickly draw up the liquid and needs to be improved. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to provide a sampling device for chemical analysis and detection, and to solve the problems mentioned in the background art.

[0005] Technical Solution: A sampling device for chemical analysis and detection includes a second housing, on the upper surface of which a first housing is disposed. The first housing and the second housing are adhered and fixed together. A battery is installed inside the first housing. A through groove is formed at the bottom of the second housing. A miniature electric push rod is disposed at the upper part of the interior of the second housing and is fixedly connected to the second housing. A hollow tube is disposed inside the second housing near the lower part of the miniature electric push rod and is fixedly connected to the second housing. A circular hole is formed at the top of the hollow tube. The output shaft of the miniature electric push rod passes through the interior of the hollow tube. A rubber disc is disposed at the output end of the miniature electric push rod and is adhered and fixed to the output end of the miniature electric push rod. A threaded ring is disposed at the lower part of the inner wall of the hollow tube and is adhered and fixed to the hollow tube. A threaded suction tube tail is disposed on the inner wall of the threaded ring and is threadedly connected to the threaded ring. A disposable suction tube is disposed at the bottom end of the threaded suction tube tail and is adhered and fixed to the threaded suction tube tail.

[0006] Furthermore, a button is provided on the front surface of the second housing, and the button is fixedly connected to the second housing.

[0007] Furthermore, the rubber disc is located on the inner wall of the hollow tube, and the rubber disc is slidably connected to the hollow tube.

[0008] Furthermore, a charging port is installed on the upper surface of the first housing.

[0009] Furthermore, the center of the threaded ring and the center of the through groove coincide, and the tail of the threaded suction tube penetrates the through groove, with the outer diameter of the tail of the threaded suction tube being smaller than the diameter of the through groove.

[0010] Beneficial effects:

[0011] The device designed in this utility model allows the operator to hold the disposable straw and install the threaded straw tail thread into the threaded ring. It is simple to operate and has good sealing performance. When the button is pressed, the output shaft of the micro electric push rod retracts, and then the rubber disc gradually moves upward. When the disposable straw is inserted into the chemical liquid, it can extract the chemical liquid into the disposable straw with high extraction efficiency.

[0012] The device designed in this utility model has a detachable disposable straw, which makes it convenient for staff to replace it with a new one. In addition, the device is powered by a rechargeable battery, which provides a long battery life. Attached Figure Description

[0017] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] According to the appendix Figure 1-3A sampling device for chemical analysis and detection is provided, comprising a second housing 3, a first housing 1 disposed on the upper surface of the second housing 3, the first housing 1 and the second housing 3 being adhered and fixed together, a battery 12 installed inside the first housing 1, a through groove 13 formed at the bottom of the second housing 3, a miniature electric actuator 10 disposed at the upper part of the interior of the second housing 3 and fixedly connected to the second housing 3, and a hollow tube 7 disposed inside the second housing 3 near the lower part of the miniature electric actuator 10 and fixedly connected to the second housing 3. A circular hole 8 is opened at the top of the hollow tube 7. The output shaft of the micro electric push rod 10 passes through the interior of the hollow tube 7. A rubber disc 6 is provided at the output end of the micro electric push rod 10. The rubber disc 6 is glued and fixed to the output end of the micro electric push rod 10. A threaded ring 9 is provided at the bottom of the inner wall of the hollow tube 7. The threaded ring 9 is glued and fixed to the hollow tube 7. A threaded straw tail 5 is provided on the inner wall of the threaded ring 9. The threaded straw tail 5 is threadedly connected to the threaded ring 9. A disposable straw 4 is provided at the bottom of the threaded straw tail 5. The disposable straw 4 is glued and fixed to the threaded straw tail 5.

[0020] In this embodiment, a button 2 is provided on the front surface of the second housing 3. The button 2 is fixedly connected to the second housing 3 and is used to control the start and stop of the device.

[0021] In this embodiment, the rubber disc 6 is located on the inner wall of the hollow tube 7, and the rubber disc 6 is slidably connected to the hollow tube 7, allowing the rubber disc 6 to slide within the hollow tube 7.

[0022] In this embodiment, a charging port 11 is installed on the upper surface of the first housing 1 for charging the storage battery 12.
