Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of a mounting base provided in the present application, and fig. 2 is a schematic sectional structural diagram of the mounting base shown in fig. 1, where the mounting base 10 includes: a mounting cylinder 11 and a first electrode 12 disposed in the mounting cylinder 11.

Specifically, as shown in fig. 2, a partition 111 is disposed in the assembly barrel 11, and the partition 111 makes the assembly barrel 11 form a drainage chamber 112 (the drainage chamber 112 may also be referred to as a rear pool) and an assembly chamber 113. That is, the drainage lumen 112 and the assembly lumen 113 are located on opposite sides of the partition 111, respectively.

The first electrode 12 is embedded in the mounting cavity 113. That is, the separator 111 can separate the first electrode 12 from the drainage lumen 112. The first electrode 12 is integrally injection molded or detachably attached to the fitting cylinder 11.

In this embodiment, the first electrode 12 may be a columnar electrode. In other embodiments, the first electrode 12 may also be an electrode sheet.

The side wall of the drainage cavity 112 is provided with a first opening 114, the side wall of the assembly cavity 113 is provided with a second opening 115, and the first opening 114 and the second opening 115 are arranged on the same side of the assembly barrel 11. The fitting chamber 113 and the drainage chamber 112 communicate through a first opening 114 and a second opening 115. Through the arrangement mode, when the assembly seat 10 is used for sample detection, one end of the first electrode 12, which faces a microporous sheet (shown in fig. 4) in the kit, can be prevented from contacting with a sample to be detected, so that the interference of the first electrode 12 on the sample detection is reduced, and the accuracy of a sample detection result is improved.

Further, the drainage chamber 112 and the mounting chamber 113 are arranged side by side in the axial direction of the mounting barrel 11. With this arrangement, control over the shape and volume of the drainage lumen 112 is facilitated. In other embodiments, the drainage chamber 112 and the assembly chamber 113 may also be arranged along the radial direction of the assembly barrel 11 or other directions, which may be selected according to actual needs.

In this embodiment, the drainage lumen 112 and the mounting lumen 113 may be coaxially disposed. The coaxial arrangement of the drainage cavity 112 and the assembly cavity 113 can facilitate the die drawing operation after the die is formed. In other embodiments, the drainage lumen 112 and the mounting lumen 113 may not be coaxially disposed.

In the embodiment shown in FIG. 2, the bottom wall of the drainage lumen 112 can be flared to form a drainage surface on the bottom wall to quickly drain liquid or air bubbles within the drainage lumen 112 to the first opening 114. In other embodiments, the bottom wall of the drainage lumen 112 can also be a planar structure or an arcuate structure, etc.

The first opening 114 and the second opening 115 may have a circular hole shape, a kidney-shaped hole shape, a rectangular hole shape, or the like.

Further, as shown in fig. 1, the outer surface of the fitting cylinder 11 is provided with a recessed area communicating with the first opening 114 and the second opening 115 to form a coupling groove 116. The depth of the recess of the connecting groove 116 is 1/5-4/5 of the wall thickness of the assembling cylinder 11. Liquid in the drainage lumen 112 passes through the first opening 114 and the connecting slot 116 to the second opening 115.

Optionally, the connecting slot 116 is located between the first opening 114 and the second opening 115, and this arrangement can shorten the flow path of the liquid sucked from the drainage chamber 112 and improve the efficiency of sample detection. In other embodiments, connecting slot 116 may also be another slot disposed in a bent manner to connect first opening 114 and second opening 115, as long as first opening 114 and second opening 115 can be communicated with each other, which is not listed here.

Optionally, an end of the bottom wall of the connecting groove 116 close to the first opening 114 is disposed obliquely to form a flow guide surface 1161, and the flow guide surface 1161 is an oblique arc surface or an oblique plane. Flow directing surface 1161 is capable of directing fluid within drainage lumen 112 into connecting slot 116 through first opening 114.

Further, as shown in fig. 1, the outer surface of the fitting cylinder 11 is provided with a recessed area communicating with the second opening 115 to form a guide groove 117. The guide groove 117 is circumferentially provided along the outer surface of the fitting cylinder 11. The depth of the depression of the diversion trench 117 is 1/5-4/5 of the wall thickness of the assembly cylinder 11.

The liquid in drainage chamber 112 is guided into connecting groove 116 from first opening 114 via guiding surface 1161, and then flows into second opening 115 from connecting groove 116 and flows out via guiding groove 117.

The first electrode 12 is embedded in the fitting cavity 113. Alternatively, the first electrode 12 may be embedded in the mounting cavity 113 by injection molding and flush, protruded or recessed on the outer end surface of the mounting seat 10.

Preferably, the first electrode 12 extends to the second opening 115, and blocks the passage of the second opening 115 communicating with the mounting cavity 113. By this arrangement, it is avoided that liquid in the drainage lumen 112 can enter the mounting lumen 113 through the second opening 115 when the liquid flows to the second opening 115.

Further, as shown in fig. 1 and 2, the assembly cylinder 11 includes a rear cell cylinder 13, an end plate 14 and an outer cylinder 15 which are integrally connected, the rear cell cylinder 13 is provided with a drainage cavity 112, an assembly cavity 113, a first opening 114 and a second opening 115, the end plate 14 radially connects the rear cell cylinder 13 and the outer cylinder 15, and the outer cylinder 15 is disposed on the periphery of the rear cell cylinder 13 and spaced apart from the rear cell cylinder 13.
