[0039] As shown in FIG. 1, the support 100 is provided with a slide 110.

[0040] As shown in FIG. 1, the support 100 is provided with a slide 110.

[0041] As shown in FIG. 1, the support 100 is provided with a slide 110.

[0042] As shown in FIG. 1, the support 100 is provided with a slide 110.

[0043] As shown in FIG. 1, the support 100 is provided with a slide 110. Figure 1 and Figure 2 As shown in FIG. 1, the support 100 is provided with a slide 110.

[0044] As shown in Figure 6 and Figure 7 , the drip head 200 has a liquid inlet 210 and a pressure port 220; as shown in Figure 1 , the drip head 200 is provided with a pressure port 220, one end of which is installed at the connecting hole 120 of the support 100, so that the drip head 200 is connected to the connecting hole 120 through the pressure port 220, and the pressure port 220 is connected to the pressure regulating port 350 through the connecting hole 120.

[0045] Exemplarily, the drip head 200 sucks the sample through the liquid inlet 210. Exemplarily, the drip head 200 is made of transparent material, such as glass, plastic, etc. The drip head 200 is provided with a scale line.

[0046] The plurality of equidistantly distributed connecting holes 120 provided on the support 100 enable the drip head 200 to be installed as needed, realizing the modular design of the mechanical structure.

[0047] As shown in Figure 1 , the pressure regulating port 350 can be in communication with the connecting hole 120, so that the pressure regulating member 300 connects the pressure port 220 of the drip head 200 through the pressure regulating port 350 and the connecting hole 120, and the pressure regulating member 300 can adjust the air pressure in the drip head 200.

[0048] Exemplarily, one end of the pressure port 220 of the drip head 200 is threadedly matched with the connecting hole 120 of the support 100, and in another embodiment, one end of the pressure port 220 of the drip head 200 is snap-fitted with the connecting hole 120 of the support 100.

[0049] The number of drip heads 200 is matched with the number of connecting holes 120. For example, if two connecting holes 120 are provided, two drip heads 200 are correspondingly provided. In another embodiment, if four connecting holes 120 are provided, four drip heads 200 are correspondingly provided. In yet another embodiment, if ten connecting holes 120 are provided, ten drip heads 200 are correspondingly provided. In another embodiment, if twelve connecting holes 120 are provided, twelve drip heads 200 are correspondingly provided.

[0050] As shown in Figure 1 , in one embodiment, the combined dropper further comprises a movable member 400. The movable member 400 is provided to enable the pressure regulating port 350 of the pressure regulating member 300 to be in sealing cooperation with the pressure port 220 of the drip head 200, to improve the sealing property, and to ensure the efficiency of the pressure regulating member 300 in adjusting the air pressure of the drip head 200, so as to make the sampling of the drip head 200 more accurate and sensitive.

[0051] As shown in Figure 1 and Figure 8As shown, the movable part 400 is slidingly installed in the connecting hole 120, so that it is easy to disassemble and clean. When the movable part 400 or the connecting hole 120 is worn or contaminated, the user can easily replace or clean it, ensuring the hygiene and accuracy of the sampling process.

[0052] The movable part 400 is in sealing cooperation with the inner wall of the connecting hole 120. The movable part 400 has a matching through hole 410 coaxial with the connecting hole 120. The matching through hole 410 has a first opening 412 for sealingly connecting the pressure regulating port 350 and a second opening 414 for sealingly connecting the pressure port 220, so that the pressure regulating port 350 of the pressure regulating part 300 and the pressure port 220 of the dripper 200 are sealingly connected through the matching through hole 410.

[0053] An outer thread is arranged on the outer wall at the pressure regulating port 350, and an inner thread is arranged on the inner wall of the first opening 412, which cooperates with the outer thread at the pressure regulating port 350.

[0054] During use, the pressure regulating part 300 is rotated in the forward direction, so that the movable part 400 axially approaches the pressure regulating part 300, and then the pressure regulating part 300 and the movable part 400 are in sealing cooperation. The pressure regulating part 300 is rotated in the reverse direction, so that the movable part 400 axially moves away from the pressure regulating part 300, and then the pressure regulating part 300 and the movable part 400 are disengaged. In this way, the pressure regulating part 300 can slide on the slide 110, so that the pressure regulating part 300 can switch to cooperate with other movable parts 400 and drippers 200.

[0055] As shown in Figure 1 and Figure 8 In one embodiment, the outer wall of the movable part 400 is a stepped shaft surface 420. The design of the stepped shaft surface 420 can make the stress distribution on the movable part 400 more uniform. The stepped shaft surface 420 can also reduce the contact area between the outer wall of the movable part 400 and the inner wall of the connecting hole 120, thereby reducing the friction between the movable part 400 and the inner wall of the connecting hole 120.

[0056] As shown in Figure 4 and Figure 5 In one embodiment, the pressure regulating part 300 includes a dripper rod 310, a rubber head 320, and a threaded joint 330.

[0057] The dripper rod 310 is a sleeve structure with open ends. As shown in Figure 1 One end of the dripper rod 310 is open in the slide 110, and the other end of the dripper rod 310 extends out of the slide 110, facilitating the user to hold the dripper rod 310.

[0058] The rubber head 320 is arranged on the end of the dripper rod 310 away from the slide 110, facilitating the user to pinch the rubber head 320.

[0059] The threaded connector 330 is located on the drip rod 310 at one end of the opening near the slide 110, and the pressure regulating port 350 is located on the threaded connector 330.

[0060] The user squeezes the nozzle 320 to change the air pressure inside the dripping rod 310. The air pressure change is transmitted through the dripping rod 310 and the threaded connector 330 to the pressure regulating port 350, and then through the pressure regulating port 350 and the through hole 410 to the dripping head 200, thereby adjusting the air pressure of the dripping head 200.

[0061] like Figures 1 to 3 As shown, in one embodiment, the slide 110 has a wedge-shaped opening 112.

[0062] The connection between the drip rod 310 and the threaded joint 330 is a funnel-shaped fitting part 340 that adapts to the wedge-shaped opening 112 of the slide rail 110, so that the pressure regulating component 300 is kept fixed in the axial direction, improving the fit between the pressure regulating component 300 and the slide rail 110, reducing the shaking and deviation of the pressure regulating component 300 when it moves on the slide rail 110, and improving the stability and reliability of the entire mechanical structure.

[0063] The funnel-shaped mating part 340 allows the pressure regulating component 300 to move more smoothly when switching between different drip heads 200. Due to the tight fit between the mating part and the wedge-shaped opening 112, the movement of the pressure regulating component 300 on the slide 110 is more stable, reducing friction and resistance, thereby improving the efficiency and smoothness of switching.

[0064] In one embodiment, a first internal thread is provided at the opening of the connecting hole 120 near the dropper 200, and a first external thread is provided on the outer wall of the pressure port 220 of the dropper 200 to mate with the first internal thread. The first external thread of the dropper 200 mates with the first internal thread in the connecting hole 120. Rotating the dropper 200 allows it to move axially, bringing it closer to the movable part 400. This ensures a sealing fit between the pressure head and the second opening 414, improving the gas-tightness and reducing gas leakage and pressure loss during pressure regulation. This, in turn, improves the pressure regulation accuracy of the pressure regulating component 300 on the dropper 200. This improved pressure regulation accuracy directly leads to improved sampling accuracy. In applications requiring precise control of sample volume, such as chemical analysis and environmental monitoring, this high-precision sampling capability is crucial. By improving the pressure regulation accuracy of the pressure regulating component 300 on the dropper 200, it ensures that each sample is more accurate and reliable.

[0065] like Figure 8 As shown, in one embodiment, a first sliding engagement member 430 is provided on the outer wall of the movable member 400.

[0066] A second sliding engagement component is provided on the inner wall of the connecting hole 120 to engage with the first sliding engagement component 430.

[0067] For example, the first sliding engagement member 430 is a groove, and the second sliding engagement member is a protrusion that slides with the groove. However, in another embodiment, the first sliding engagement member is a protrusion, and the second sliding engagement member is a groove that slides with the protrusion.

[0068] In one embodiment, the number of support members 100 is two or more, and adjacent support members 100 are detachably connected. Exemplarily, two support members 100 may be provided. In another embodiment, three support members 100 may be provided. In yet another embodiment, four support members 100 may be provided. Of course, the number of support members 100 can also be five, six, ten, etc.

[0069] like Figures 1 to 3 As shown, in one embodiment, the support member 100 is provided with a T-shaped protrusion 130 and a T-shaped slot 140, and adjacent support members 100 are detachably connected through the T-shaped protrusion 130 and the T-shaped slot 140.

[0070] For example, two support members 100 are provided, with the T-shaped protrusion 130 of one support member 100 engaging with the T-shaped slot 140 of the other support member 100 to connect the two support members 100. In another embodiment, three support members 100 are provided, namely a first support member 100, a second support member 100, and a third support member 100. The T-shaped protrusion 130 of the first support member 100 engages with the T-shaped slot 140 of the second support member 100, and the T-shaped protrusion 130 of the second support member 100 engages with the T-shaped slot 140 of the third support member 100.

[0071] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
