[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0022] As used herein, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase does not necessarily refer to the same embodiment at every occurrence in the specification, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of the detection component 100 in some embodiments of the present application. The detection component 100 generally includes a first clamping member 10, a second clamping member 20, and a ring body 30 clamped between the first clamping member 10 and the second clamping member 20.

[0024] Specifically, the first clamping member 10 has a first surface 10a, the second clamping member 20 has a second surface 20a, and the ring body 30 is clamped between the first surface 10a of the first clamping member 10 and the second surface 20a of the second clamping member 20 to form an accommodation space 301 inside the ring body 30. It can be understood that the first clamping member 10 further has a third surface 10b opposite to the first surface 10a, and the second clamping member 20 further has a fourth surface 20b opposite to the second surface 20a. Among them, a plurality of detection electrodes (to be further specifically described below) are provided on the second surface 20a of the second clamping member 20 for detecting electrochemical parameters such as pH value, hematocrit, ion concentration (K+, Na+, Cl-, Ca2+), glucose, lactic acid, and partial pressures of O2 and CO2 in the liquid in the accommodation space 301.

[0025] Further, the first clamping member 10 and / or the second clamping member 20 are provided with a liquid inlet 201 and a liquid outlet 202, and the liquid inlet 201, the accommodating space 301, and the liquid outlet 202 are in communication. Preferably, the liquid inlet 201 and the liquid outlet 202 penetrate through the second clamping member 20 respectively to communicate with the accommodating space 301. Among them, the liquid inlet 201 and the liquid outlet 202 are arranged at intervals. The shape of the liquid inlet 201 can be circular, rectangular, polygonal, etc., and the shape of the liquid outlet 202 can be circular, rectangular, polygonal, etc., which will not be elaborated. It can be understood that the shapes of the liquid inlet 201 and the liquid outlet 202 can be the same or different. Preferably, the axis lines of the liquid inlet 201 and the liquid outlet 202 are arranged substantially parallel and at intervals. It should be understood that the use of the terms "substantially, generally" in this application in terms of digital quantities or other quantifiable relationships (such as perpendicularity or parallelism) should be understood to indicate a quantity of ±10%. Therefore, for example, lines that are generally parallel to each other can form an angle between 0° and 10° with each other.

[0026] The detection component provided by the embodiment of the present application is clamped between the first clamping member and the second clamping member through a ring body, and an accommodating space is formed inside the ring body. At the same time, a liquid inlet and a liquid outlet communicating with the accommodating space are provided on the first clamping member and / or the second clamping member, so that the external liquid of the detection component can flow into the detection component from the liquid inlet to complete the corresponding detection. After the detection is completed, the liquid in the accommodating space can flow out of the detection component from the liquid outlet and will not be stored inside the detection component, which can greatly reduce the volume of the detection component. At the same time, the liquid can flow into and out of the detection component, so that the detection component can realize multiple repeated measurements, greatly improving the number of measurements of the detection component, without the need to frequently replace the detection component, and the test efficiency is high. In addition, the detection component can be reused, which can save the consumable cost to a certain extent.

[0027] It can be understood that the "detection component" can also be called a "blood gas biochemical test card" or a "test box". The detection component can cooperate with a blood gas analysis device to measure parameters such as pH value, hematocrit, ion concentration (K+, Na+, Cl-, Ca2+), glucose, lactic acid, and partial pressures of O2 and CO2 in a blood sample. Among them, the detection component generally can use electrochemistry or AC impedance method to complete the above parameter measurements.

[0028] Among them, the "blood gas analysis device" can also be called a "blood gas analyzer" or a "blood gas biochemical analyzer", which utilizes blood gas analysis technology. Blood gas analysis technology refers to a technical means applied to a blood gas analysis device, which can understand the respiratory function and acid-base balance state of the human body by measuring the H+ concentration, gases dissolved in the blood (mainly CO2, O2, etc.) and other parameters in a blood sample. It can directly reflect the pulmonary gas exchange function and its acid-base balance state, and the specimen used is usually a blood sample.

[0029] Please refer to Figures 2 to 5 , Figure 2 which is a schematic structural diagram of the detection component 100 in some other embodiments of the present application, Figure 3 and Figure 2 is a schematic diagram of the structural disassembly of the detection component 100 in the embodiment. Figure 4 And Figure 2 is a schematic cross-sectional structural diagram of the detection component 100 along the A-A direction in the embodiment. Figure 5 And Figure 2 is a schematic structural diagram of the second clamping member 20 and the ring body 30 in cooperation in the embodiment. Among them, the first clamping member 10 can be made of rigid materials such as plastics, resins, and polymer materials. For example, the first clamping member 10 can be made of ABS (Acrylonitrile Butadiene Styrene plastic), PDMS (Polydimethylsiloxane), PC (Polycarbonate), PMMA (Polymethyl methacrylate), PS (General purpose polystyrene), PP (Polypropylene), COC (copolymers of cycloolefin), etc., and can be processed by injection molding, numerical control machine tool processing, 3D printing or other processing methods. The material of the second clamping member 20 can be the same as or different from that of the first clamping member 10. Preferably, the second clamping member 20 can be a circuit board, that is, a plurality of detection electrodes are provided on the second clamping member 20 to realize the detection of electrochemical parameters and establish a signal connection with an external device (such as a blood gas analysis device).

[0030] A receiving groove 101 is formed on the first surface 10a of the first clamping member 10. The second clamping member 20 is received in the receiving groove 101, and the outer peripheral edge of the second clamping member 20 is adapted to the inner side wall of the receiving groove 101. The liquid inlet 201 and the liquid outlet 202 are provided on the second clamping member 20.

[0031] Among them, the second clamping member 20 can be connected and fixed to the first clamping member 10 by connection methods such as screwing, plugging, buckling, bonding, and welding. In one embodiment, the second clamping member 20 can be connected and fixed to the bottom wall of the receiving groove 101 by connection methods such as screwing, plugging, buckling, bonding, and welding. Generally speaking, the receiving groove 101 generally includes a bottom wall 101a and side walls 101b extending from the edge of the bottom wall 101a, that is, the bottom wall 101a and the side walls 101b enclose the receiving space of the receiving groove 101.

[0032] In one embodiment, at least one first positioning post 203 is provided on the inner side wall of the accommodating groove 101, and at least one first positioning hole 204 corresponding to the first positioning post 203 is formed on the second clamping member 20. Wherein, the first positioning post 203 and the first positioning hole 204 cooperate to position the second clamping member 20 when the second clamping member 20 is assembled in the accommodating groove 101. Preferably, the first positioning post 203 is provided on the bottom wall 101a, and two first positioning posts 203 may be provided. The two first positioning posts 203 are arranged in the diagonal regions of the bottom wall 101a; two first positioning holes 204 may also be provided. The two first positioning holes 204 are distributed in the diagonal regions of the second clamping member 20. Wherein, the first positioning posts 203 and the first positioning holes 204 are arranged in one-to-one correspondence. Of course, it can be understood that the first positioning posts 203 and the first positioning holes 204 can adopt an anti-fooling setting method to avoid the reverse installation phenomenon of the second clamping member 20 during assembly.

[0033] The annular body 30 can be received in the accommodating groove 101 and is arranged between the second clamping member 20 and the bottom wall 101a, that is, the annular body 30 is arranged on the side of the second clamping member 20 close to the bottom wall 101a, and the opposite sides of the annular body 30 are respectively abutted against the bottom wall 101a and the second clamping member 20. In other words, the second clamping member 20 and the bottom wall 101a cooperate to clamp the annular body 30, so that the annular body 30 is in interference fit with the second clamping member 20 and the bottom wall 101a respectively to achieve sealing. Wherein, the annular body 30 can be connected and fixed to the first clamping member 10 and / or the second clamping member 20 through connection methods such as screwing, plugging, buckling, welding, and bonding.

[0034] The annular body 30 can be in a plate shape or a sheet shape. Of course, it can also be in other shapes, which will not be elaborated. The annular body 30 is generally annular, and the opposite two sides of the annular body 30 are respectively abutted against the first clamping member 10 and the second clamping member 20 to form an accommodating space 301 inside the annular body 30. In other words, the annular body 30 is arranged between the second clamping member 20 and the first clamping member 10, and an accommodating space 301 is formed by surrounding when the second clamping member 20 and the first clamping member 10 clamp the annular body 30.

[0035] Wherein, the annular body 30 can be made of materials with certain elasticity such as rubber and silica gel. For example, the annular body 30 is made of silica gel and the accommodating space 301 is formed by an integral molding process (such as injection molding). Of course, in other embodiments, the annular body 30 can be formed by a stamping process. It can be understood that the accommodating space 301 can be used for fluid to flow or stand still. Further, the annular body 30 made of materials with certain elasticity such as rubber and silica gel can facilitate the first clamping member 10 and the second clamping member 20 to seal the accommodating space 301 by interference fit when clamping the annular body 30, so that the accommodating space 301 is only communicated with the liquid inlet 201 and the liquid outlet 202, avoiding liquid leakage.

[0036] The liquid inlet 201 and the liquid outlet 202 are respectively communicated with the accommodating space 301, so that the external liquid of the detection component 100 can flow into the accommodating space 301 from the liquid inlet 201, and then can flow out of the detection component 100 through the liquid outlet 202. Wherein, the liquid inlet 201 and the accommodating space 301 at least partially overlap in the axial direction of the liquid inlet 201, that is, the thickness direction of the annular body 30, and the liquid outlet 202 and the accommodating space 301 at least partially overlap in the axial direction of the liquid outlet 202, that is, the thickness direction of the annular body 30.

[0037] In other words, the annular body 30 is disposed around the peripheries of the liquid inlet 201 and the liquid outlet 202, that is, the liquid inlet 201 and the liquid outlet 202 are at least partially exposed in the accommodating space 301, so that the liquid flowing in from the liquid inlet 201 can flow into the accommodating space 301, and the liquid in the accommodating space 301 can flow out of the detection component 100 through the liquid outlet 202. In an embodiment, the orthographic projection of the liquid inlet 201 on the annular body 30 is adjacent to the outer peripheral edge of the accommodating space 301 and is located within the accommodating space 301. The orthographic projection of the liquid outlet 202 on the annular body 30 is adjacent to the outer peripheral edge of the accommodating space 301 and is located within the accommodating space 301.

[0038] It can be understood that the liquid inlet 201 and the liquid outlet 202 are respectively adjacent to the two ends of the accommodating space 301 that are oppositely arranged along the liquid flow direction in the accommodating space 301, so that the flow distance of the liquid in the accommodating space 301 is approximately equal to or slightly greater than the distance between the liquid inlet 201 and the liquid outlet 202, and the length of the accommodating space 301 along the liquid flow direction is approximately equal to or slightly greater than the distance between the liquid inlet 201 and the liquid outlet 202.

[0039] In an embodiment, an assembly groove 1011 is provided on the bottom wall 101a of the accommodating groove 101, and at least a part of the annular body 30 is embedded in the assembly groove 1011 and is in interference fit with the assembly groove 1011 to seal one side of the accommodating space 301. Embedding the annular body 30 in the bottom wall 101a can not only avoid the dislocation of the annular body 30 during assembly, but also improve the tightness of the accommodating space 301 and avoid liquid leakage. The shape of the assembly groove 1011 is adapted to the outer peripheral edge of the annular body 30.

[0040] Of course, in other partial embodiments, when the second clamping member 20 cooperates with the assembly groove 1011 to clamp the annular body 30, the thickness of the annular body 30 in the axial direction of the liquid inlet 201 is substantially the same as the depth of the assembly groove 1011. At this time, the second clamping member 20 abuts against the bottom wall 101a of the accommodating groove 101 to achieve a sealing effect. It can be understood that when the second clamping member 20 and the assembly groove 1011 cooperate to clamp the annular body 30, the annular body 30 can be in interference fit with the assembly groove 1011 and the second clamping member 20 respectively, so as to achieve a sealing effect.

[0041] The detection component provided in the embodiment of the present application is clamped between the first clamping member and the second clamping member through a ring body, and a containing space is formed inside the ring body. At the same time, a liquid inlet and a liquid outlet connected to the containing space are arranged on the first clamping member and / or the second clamping member, so that the liquid outside the detection component can flow into the detection component from the liquid inlet to complete the corresponding detection. After the detection is completed, the liquid in the containing space can flow out of the detection component from the liquid outlet, and will not be stored inside the detection component, which can greatly reduce the volume of the detection component. At the same time, the liquid can flow into and out of the detection component, so that the detection component can achieve repeated measurements for many times, which greatly improves the number of measurements of the detection component, and there is no need to frequently replace the detection component, and the test efficiency is high.

[0042] As mentioned above, the second clamping member 20 is provided with a plurality of detection electrodes to realize electrochemical parameter detection and establish signal connection with external equipment. The plurality of detection electrodes on the second clamping member 20 generally include at least one test electrode 21 and at least one external electrode 22 .

[0043] Specifically, the test electrode 21 and the external electrode 22 can be arranged on the same side or different sides of the second clamping member 20, and the embodiment of the present application does not impose specific restrictions on this. The following is an example in which the test electrode 21 and the external electrode 22 are both arranged on the side of the second clamping member 20 close to the ring body 30. Among them, the test electrode 21 is exposed in the accommodating space 301, and the external electrode 22 is arranged outside the accommodating space 301; the test electrode 21 and the external electrode 22 are electrically connected, and the external electrode 22 is configured to establish a signal connection with an external detection device.

[0044] In one embodiment, the bottom wall 101a of the receiving groove 101 is provided with a test port 1010, and the test port 1010 and the ring body 30 are spaced apart, that is, the test port and the assembly groove 1011 are spaced apart. In other words, the first clamping member 10 is provided with a test port 1010 corresponding to the second surface 20a of the second clamping member 20, and the external electrode 22 is exposed from the test port 1010 to the side of the first clamping member 10 away from the first surface 10a. That is, the external electrode 22 is provided corresponding to the test port 1010, and can be exposed from the test port 1010 to the outside of the detection component 100, so that multiple external electrodes 22 can be connected to the connector of the external device, thereby completing the corresponding test operation and signal transmission.

[0045] It can be understood that the plurality of external electrodes 22 may be distributed in an array, or in a single row, multiple rows, or in other distribution modes, which will not be elaborated in this embodiment.

[0046] A plurality of test electrodes 21 are arranged corresponding to the accommodating space 301 and are exposed to the accommodating space 301. In other words, the annular body 30 surrounds the periphery of the plurality of test electrodes 21 so that the liquid in the accommodating space 301 can completely cover the plurality of test electrodes 21, and thus operations such as cleaning, calibration, and testing can be completed.

[0047] It can be understood that the plurality of test electrodes 21 can be arranged in an array, or can be arranged in a single row or multiple rows or other distribution methods, which will not be elaborated in this embodiment.

[0048] In some embodiments, a reference electrode 23 is further provided on the side of the second clamping member 20 close to the annular body 30. The reference electrode 23 is arranged corresponding to the accommodating space 301 and is exposed to the accommodating space 301. In other words, the annular body 30 surrounds the periphery of the reference electrode 23 so that the liquid in the accommodating space 301 can completely cover the reference electrode 23. Among them, the plurality of test electrodes 21 are arranged in sequence in the liquid flow direction in the accommodating space 301, and the reference electrode 23 can be arranged between two adjacent test electrodes 21.

[0049] Among them, the reference electrode 23 can be linearly distributed with the test electrodes 21, or the reference electrode 23 can be selected from one or more of the plurality of test electrodes 21, that is, one or some of the plurality of test electrodes 21 can be reused as the reference electrode 23. That is, the separately provided reference electrode 23 can be cancelled, that is, one or more of the plurality of test electrodes 21 are reused as the reference electrode 23, so as to further reduce the trough length of the accommodating space 301 in the fluid flow direction, thereby realizing the measurement with the minimum sample volume.

[0050] For example, the plurality of test electrodes 21 are arranged in sequence in the liquid flow direction in the accommodating space 301, that is, the plurality of test electrodes 21 are arranged in a single row, the liquid inlet 201 penetrates through the first test electrode 21 among the sequentially arranged plurality of test electrodes 21, and the liquid outlet 202 penetrates through the last test electrode 21 among the sequentially arranged plurality of test electrodes 21. At this time, the trough length of the accommodating space 301 in the fluid flow direction can be minimized, so that the liquid in the accommodating space 301 can be minimized during a single measurement, and thus the measurement with the minimum sample volume can be realized. Of course, in other embodiments, the plurality of test electrodes 21 can also be arranged in multiple rows, the liquid inlet 201 penetrates through the first test electrode 21 among one row of the multiple rows of test electrodes 21, and the liquid outlet 202 penetrates through the last test electrode 21 among one row of the multiple rows of test electrodes 21, so as to realize the measurement with the minimum sample volume.

[0051] The detection component provided in this embodiment is configured such that the annular body is disposed around the periphery of the liquid inlet and the liquid outlet, and the two ends of the accommodation space provided inside the annular body that are oppositely disposed along the liquid flow direction are respectively adjacent to the liquid inlet and the liquid outlet, thereby reducing the flow distance of the liquid within the accommodation space, and further enabling measurement with a minimum sample volume. Additionally, the annular body surrounds the periphery of multiple test electrodes, and the liquid inlet and the liquid outlet respectively penetrate through the first test electrode and the last test electrode among the multiple test electrodes, further reducing the flow distance of the liquid within the accommodation space, and can greatly reduce the sample volume in a single measurement operation.

[0052] Please refer to Figure 6 , Figure 6 which is a schematic cross-sectional structure diagram of the annular body 30 in some other embodiments of the present application. The difference between the annular body 30 in this embodiment and the annular body 30 in the foregoing embodiment is that: the accommodation space 301 is generally a blind hole structure.

[0053] Specifically, the annular body 30 generally includes a bottom surface 30a and a top surface 30b that are disposed opposite to each other. The bottom surface 30a abuts against the second clamping member 20, and the top surface 30b abuts against the bottom wall 101a. A blind hole structure accommodation space 301 is formed on the bottom surface 30a, that is, the bottom surface 30a is recessed in a direction away from the second clamping member 20 to form the accommodation space 301. At this time, the accommodation space 301 is spaced apart from the bottom wall 101a, and the annular body 30 can form the accommodation space 301 only in cooperation with the second clamping member 20. It can be understood that, compared with the through-hole structure accommodation space 301 in the foregoing embodiment, the blind hole structure accommodation space 301 provided in this embodiment only needs to ensure the airtightness between the annular body 30 and the test board, and the sealing effect is relatively good.

[0054] Please refer to Figures 7 to 9 , Figure 7 which is a schematic structural diagram of the detection component 200 in some other embodiments of the present application, Figure 8 is Figure 7 a schematic diagram of the structural disassembly of the detection component 200 in the embodiment, Figure 9 is Figure 7 a schematic cross-sectional structure diagram of the detection component 200 along the B-B direction in the embodiment. The detection component 200 generally includes a first clamping member 10, a second clamping member 20, an annular body 30 disposed between the first clamping member 10 and the second clamping member 20, and a diversion component 50 disposed on the second clamping member 20. It can be understood that the difference between the detection component 200 in this embodiment and the detection component 100 in the foregoing embodiment is that: the detection component 200 may further include a diversion component 50 disposed on the side of the second clamping member 20 that faces away from the bottom wall 101a or the annular body 30. In this embodiment, the diversion component 50 will be described in detail, and other technical features of the detection component 200 that are not elaborated herein may refer to the detection component 100 in the foregoing embodiment.

[0055] The diversion assembly 50 may include a first diversion assembly 51 and a second diversion assembly 52, and both the first diversion assembly 51 and the second diversion assembly 52 are disposed on the side of the second clamping member 20 away from the ring body 30. Among them, a first diversion hole 510 penetrating the first diversion assembly 51 is provided on the first diversion assembly 51, and a second diversion hole 520 penetrating the second diversion assembly 52 is provided on the second diversion assembly 52. The first diversion hole 510 is arranged corresponding to the liquid inlet 201 and communicated with the liquid inlet 201, so that the external liquid of the detection assembly 200 can flow into the liquid inlet 201 from the first diversion hole 510. The second diversion hole 520 is arranged corresponding to the liquid outlet 202 and communicated with the liquid outlet 202, so that the internal liquid of the detection assembly 200 can flow into the second diversion hole 520 from the liquid outlet 202 and flow out of the detection assembly 200 through the second diversion hole 520.

[0056] It should be noted that the terms "first", "second", etc. in this article are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include one or more of the said features.

[0057] In one embodiment, the first diversion hole 510 generally includes a first liquid inlet section 5101 and a first diversion section 5102 that are connected and communicated. The first liquid inlet section 5101 is arranged close to the liquid inlet 201 and communicated with the liquid inlet 201, and the first diversion section 5102 is disposed at the end of the first liquid inlet section 5101 away from the liquid inlet 201. Among them, the cross-sectional aperture of the first liquid inlet section 5101 along the B-B direction is generally the same, and the cross-sectional aperture of the first diversion section 5102 along the B-B direction gradually increases in the direction away from the liquid inlet 201, and the first diversion section 5102 is generally in a trumpet shape. It can be understood that the trumpet-shaped first diversion section 5102 facilitates the docking of the first diversion hole 510 with the external liquid pipeline.

[0058] In one embodiment, the second diversion hole 520 generally includes a second liquid outlet section 5201 and a second diversion section 5202 that are connected and communicated. The second liquid outlet section 5201 is arranged close to the liquid outlet 202 and communicated with the liquid outlet 202, and the second diversion section 5202 is disposed at the end of the second liquid outlet section 5201 away from the liquid outlet 202. Among them, the cross-sectional aperture of the second liquid outlet section 5201 along the B-B direction is generally the same, and the cross-sectional aperture of the second diversion section 5202 along the B-B direction gradually increases in the direction away from the liquid outlet 202, and the second diversion section 5202 is generally in a trumpet shape. It can be understood that the trumpet-shaped second diversion section 5202 facilitates the docking of the second diversion hole 520 with the external liquid pipeline.

[0059] It can be understood that the first diversion hole 510 can be directly or indirectly communicated with the liquid inlet 201, and the second diversion hole 520 can be directly or indirectly communicated with the liquid outlet 202. In this embodiment, the first diversion assembly 51 abuts against the side of the second clamping member 20 away from the ring body 30, so that the first diversion hole 510 is directly docked and communicated with the liquid inlet 201. The second diversion assembly 52 is disposed on the side of the second clamping member 20 away from the ring body 30, so that the second diversion hole 520 is directly docked and communicated with the liquid outlet 202.

[0060] Before measuring the test liquid, the cleaning liquid and the calibration liquid respectively flow into the accommodating space from the first diversion hole to complete the cleaning and calibration operations, and then flow out of the detection assembly from the second diversion hole, without being stored inside the detection assembly. After the test liquid flows into the accommodating space from the first diversion hole to complete the parameter measurement, it flows out of the detection assembly from the second diversion hole and is not stored inside the test card. The detection assembly provided in the present application does not need to be provided with a waste liquid container inside the detection assembly, which can greatly reduce the volume of the detection assembly and is conducive to realizing the thinning of the detection assembly. In addition, the test liquid, the cleaning liquid and the calibration liquid respectively flow into the accommodating space from the first diversion hole, and then flow out of the detection assembly through the second diversion hole, so that the detection assembly can perform multiple repeated measurements, greatly increasing the number of measurements of the detection assembly, and without frequently replacing the detection assembly, which can further improve the test efficiency.

[0061] It can be understood that in the embodiments of the present application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0063] The first diversion member 511 is generally in the shape of a columnar body, a rectangular body or other structural members. The first diversion member 511 is disposed on the side of the second clamping member 20 away from the ring body 30 and abuts against the second clamping member 20. The first diversion hole 510 penetrates through the first diversion member 511 along the axial direction of the liquid inlet 201.

[0064] The first fitting 512 is disposed on the side of the second clamping member 20 away from the annular body 30 and abuts against the second clamping member 20. The first fitting 512 is configured to position and install the first flow guide member 511 so that the first flow guide hole 510 communicates with the liquid inlet 201. Among them, the first fitting 512 can be connected and fixed to the second clamping member 20 and the first clamping member 10 through connection methods such as screwing, plugging, buckling, welding, and bonding, and the first fitting 512 cooperates with the second clamping member 20 to clamp and fix the first flow guide member 511.

The first mounting portion 5121 can be in a plate-shaped annular structure, and of course, it can also be in other shapes, which will not be elaborated. The first mounting portion 5121 can be connected and fixed to the second clamping member 20 and the first clamping member 10 through connection methods such as screwing, plugging, buckling, welding, and bonding.

[0066] Among them, the surface of the first mounting portion 5121 close to the second clamping member 20 is in almost seamless contact with the second clamping member 20.

Among them, there is at least one first annular slot 5111, for example, two. The inner side wall of the first socket hole 5123 is provided with a first annular protrusion corresponding to the first annular slot 5111 (as Figure 9 shown), and the first annular slot 5111 cooperates with the first annular protrusion to position and fix the first flow guide member 511.

[0069] It can be understood that the first diversion member 511 can be made of a material with certain elasticity, such as rubber, silica gel, etc. In the initial state where the first diversion member 511 is not squeezed, the initial volume of the first diversion member 511 is slightly larger than the volume of the first socket hole 5123, so that when the first fitting 512 and the second clamping member 20 cooperate to clamp the first diversion member 511, the first diversion member 511 can produce certain elastic deformation to further improve the stability and airtightness of the overall structure.

[0070] In one embodiment, at least one second positioning post 5124 protrudes from the surface of the first mounting portion 5121 close to the second clamping member 20, such as 2 second positioning posts 5124 shown in the figure.

[0072] In one embodiment, a first assembly groove 1012 is formed in the bottom wall of the accommodation groove 101. Among them, the first mounting hole 5125, the first assembly hole 206 and the first assembly groove 1012 are coaxially arranged, so that the bolt or screw passing through the first mounting hole 5125 and the first assembly hole 206 can be embedded in the first assembly groove 1012, thereby realizing the connection and fixation of the second clamping member 20 and the first clamping member 10. That is, in this embodiment, by providing the coaxially arranged first mounting hole 5125, the first assembly hole 206 and the first assembly groove 1012, after the positioning of the second clamping member 20 and the first diversion assembly 51 is completed, the connection and fixation of the second clamping member 20 and the first clamping member 10 and the connection and fixation of the first diversion assembly 51 and the second clamping member 20 can be directly completed at one time.

There is at least one second annular protrusion.

[0081] It is understandable that the second flow guide 521 can be made of a material with a certain elasticity, such as rubber, silicone, etc. In the initial state where the second flow guide 521 is not squeezed, the initial volume of the second flow guide 521 is slightly larger than the volume of the second sleeve hole 5223, so that when the second assembly part 522 cooperates with the second clamping part 20 to clamp the second flow guide 521, the second flow guide 521 can produce a certain elastic deformation, so as to further improve the stability and airtightness of the overall structure.

[0082] In one embodiment, at least one third positioning column 5224 is protruded on the surface of the second mounting portion 5221 close to the second clamping member 20, such as two third positioning columns 5224 shown in the figure.
