[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents the selected embodiments of the utility model.

[0043] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0044] The following is combined with Figure 1-3 The utility model is described in further detail.

[0045] like Figures 1 to 3As shown, the present disclosure provides a sample spotting instrument housing, including a shell body 10 and a cleaning assembly 20. The shell body 10 has an accommodating cavity 11 inside, and the accommodating cavity 11 is used to accommodate the sample spotting instrument. The shell body 10 is provided with a connecting portion 12, and the connecting portion 12 is used to connect with the first pipeline 30 of the sampling needle assembly and for the second pipeline 40 of the liquid storage assembly to be inserted. The cleaning assembly 20 includes a mounting member 21 and a cleaning member 22. The mounting member 21 is installed on the shell body 10. A cleaning channel 23 for the second pipeline 40 to pass through is formed in the mounting member 21. The cleaning member 22 is located in the cleaning channel 23 and connected to the channel wall of the cleaning channel 23. One end of the cleaning member 22 away from the channel wall of the cleaning channel 23 is used to contact the outer peripheral surface of the second pipeline 40.

[0046] Through the above-mentioned technical solution, since the cleaning piece 22 is connected to the channel wall of the cleaning channel 23 of the mounting piece 21, and the second pipeline 40 can pass through the cleaning piece 22, so that the end of the cleaning piece 22 away from the channel wall of the cleaning channel 23 is in contact with the outer peripheral surface of the second pipeline 40. With such a design, when the second pipeline 40 of the liquid storage assembly is connected to the connecting pipe part 12, the cleaning piece 22 can clean the attachments (such as dust particles or water stains) on the outer peripheral surface of the second pipeline 40, which is beneficial to extend the service life of the second pipeline 40.

[0047] As an implementation method, Figure 2 As shown, the mounting member 21 may include an arc-shaped plate 211, two mounting portions 212 and a first connecting member 213. The two mounting portions 212 are respectively connected to the two ends of the arc-shaped plate 211. The two mounting portions 212 are connected by adjusting bolts 214 so that the arc-shaped plate 211 forms a ring structure. The first end of the first connecting member 213 is connected to the outer peripheral wall of the arc-shaped plate 211, and the second end of the first connecting member 213 is connected to the connecting pipe portion 12.

[0048] Since the mounting member 21 can be in an annular structure and sleeved on the second pipeline 40, and then the nuts on the adjusting bolts 214 passing through the two mounting parts 212 are screwed, on the one hand, the mounting member 21 can be tightly clamped on the second pipeline 40, thereby preventing the second pipeline 40 from falling off the mounting member 21; on the other hand, the mounting member 21 can be adjusted according to the outer diameter of the second pipeline 40, so that the mounting member 21 can be suitable for second pipelines 40 with different outer diameters, which is beneficial to improving the applicability of the sample spotting instrument housing.

[0049] As an implementation manner, the cleaning member 22 may be an annular protrusion extending along the circumference of the cleaning channel 23 .

[0050] Optionally, the cleaning member 22 may be configured as a rubber member or a sponge, which is not limited in the present disclosure.

[0051] In order to improve the cleaning effect, optionally, there may be a plurality of annular protrusions, and the plurality of annular protrusions are arranged at intervals along the axial direction of the cleaning channel 23 .

[0052] As another embodiment, the cleaning member 22 is an elastic ring extending along the circumference of the cleaning channel 23. In the natural state of the elastic ring, the inner diameter of the elastic ring is smaller than the outer diameter of the pipeline.

[0053] Since the inner diameter of the elastic ring is smaller than the outer diameter of the second pipeline 40, when the second pipeline 40 passes through the elastic ring, the second pipeline 40 applies a radially outward extrusion force to the elastic ring, and the elastic ring is thus squeezed and provides a radially inward elastic force, so that the inner wall of the elastic ring remains in contact with the outer circumferential surface of the cable. In this way, a certain adhesion force can be provided between the elastic ring and the cable, so that the elastic ring can be better adhered to the second pipeline 40, which is beneficial to improving the cleaning effect of cleaning the surface of the second pipeline 40.

[0054] As an implementation method, Figure 1 As shown, the mounting member 21 may also include a second connecting member 215 and a sealing member 216. The second end of the first connecting member 213 is connected to the second connecting member 215. One end of the second connecting member 215 is used to be connected to the connecting pipe portion 12, and a sealing member 216 is arranged between the connecting pipe portion 12. The other end of the second connecting member 215 is connected to the second pipeline 40.

[0055] The sealing member 216 can improve the reliability of the connection between the second connecting member 215 and the connecting pipe portion 12 , so that the cleaning assembly 20 can be connected to the connecting pipe portion 12 through the first connecting member 213 and the second connecting member 215 .

[0056] Alternatively, if Figure 3 As shown, there are multiple connecting pipes 12 , which are spaced apart along the up-and-down direction of the shell body 10 , and the number of cleaning assemblies 20 and the number of second connecting members 215 are both multiple and correspond one-to-one to the number of connecting pipes 12 .

[0057] It should be understood that the liquid storage assembly further includes a third pipeline 41, a clean water bottle connected to the third pipeline 41, a fourth pipeline 42, a disinfectant bottle connected to the fourth pipeline 42, a fifth pipeline 43, and a slow-release liquid bottle connected to the fifth pipeline 43. Among them, one end of the third pipeline 41 away from the clean water bottle, one end of the fourth pipeline 42 away from the disinfectant bottle, and one end of the fifth pipeline 43 away from the slow-release liquid bottle are all connected to the second pipeline 40.

[0058] When sampling, the cleaning valve and the slow-release liquid suction valve are closed, the suction valve is opened, the slow-release liquid in the sample tube storing the slow-release liquid is sucked and the slow-release liquid is applied to the chip through the sampling needle. After sampling, the sampling needle is removed, the suction valve and the slow-release liquid suction valve are closed, the cleaning valve is opened, the first valve on the fourth pipeline 42 connected to the disinfectant bottle is opened, and the corresponding hydraulic pump draws disinfectant to disinfect the sampling needle. After that, the first valve on the third pipeline 41 connected to the clean water bottle is opened, and the corresponding hydraulic pump draws clean water to rinse the sampling needle, thereby cleaning the inside of the sampling needle. The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
