[0043] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0045] Embodiment 1:

[0046] See also Figure 1 and Figure 2 The embodiment of the present application provides a housing 100, which is applied to a pipette and used as the housing 100 of the pipette. Specifically, the housing 100 has a mounting surface 101 formed with a protrusion 110, one side of the protrusion 110 is an inclined surface 111, and the inclined surface 111 and the mounting surface 101 are enclosed to form a mounting position 120, and the mounting position 120 is used to install the protrusion 110 on another housing 100; and an angle is formed between the inclined surface 111 and the mounting surface 101, and the angle is an obtuse angle.

[0047] Understandably, the mounting surface 101 on the shell 100 is an adjacent surface adjacent to the inclined surface 111 of the protrusion 110. On the one hand, the mounting surface 101 on the shell 100 is connected to the inclined surface 111 on the protrusion 110 to form a mounting position 120, which is used to reserve an installation space for the protrusion 110 on the shell 100 in the other pipette when two pipettes are spliced, so that the connection of the shells 100 on the two pipettes after splicing is more compact, and it is easier to meet the minimum installation spacing requirement between two adjacent pipettes, thereby reducing the design difficulty; on the other hand, the mounting surface 101 on the shell 100 is connected to the inclined surface 111 on the protrusion 110 to form an obtuse angle, so that the inclined surface 111 is inclined in the direction where the protrusion 110 is away from the mounting position 120, so as to increase the connection area between the protrusion 110 and the shell 100, and improve the connection strength between the protrusion 110 and the shell 100, thereby improving the impact resistance of the protrusion 110, and then improving the stability of the shell 100 when applied to the pipette.

[0048] For example, when the housing 100 of the present application is applied to a pipette, the side of the protrusion 110 away from the mounting surface 120 is used for providing a liquid extraction gun head 210 (see Figure 4 ) installation, due to the improved impact resistance of the protrusion 110, the protrusion 110 can withstand the liquid collection gun head 210 (see Figure 4 ) is installed to the liquid collection end of the pipette, thereby improving the durability and stability of the housing 100.

[0049] In some embodiments, see Figure 1 and Figure 2 The protrusion 110 has a positioning area 130 corresponding to the position of the liquid collection end of the pipette, and the positioning area 130 has a positioning center O. It can be understood that the positioning area 130 is an area formed by the positive projection of the liquid collection end of the pipette onto the protrusion 110.

[0050] Further, see Figure 1 and Figure 2 , the width of the protrusion 110 away from the mounting surface 101 is m, the width of the protrusion 110 close to the mounting surface 101 is n, the horizontal distance from the positioning center O to the side of the protrusion 110 away from the mounting position 120 is g, the vertical distance from the positioning center O to the protrusion 110 away from the mounting surface 101 is h, the angle is θ, and the radius of the positioning area is r; the preset horizontal distance from the positioning center O to the inclined surface 111 is l, and the protrusion 110 and the positioning center O satisfy at least one of the following relationships:

[0051] (1)

[0052] (2)

[0053] Understandably, in the above relationship (1), by making the horizontal distance from the positioning center O of the pipette to the inclined surface 111 equal to the preset horizontal distance l, the mutual relationship between the position of the positioning center O within the protrusion 110 and the inclination angle θ of the inclined surface 111 is restricted, so as to achieve that the connection of the housings 100 on the two pipettes after splicing is more compact, improve the impact resistance of the protrusion 110, and at the same time make the distance between the two pipettes after splicing meet the requirement of the minimum installation distance, thereby improving the service performance of the housing 100 of the present application.

[0054] In the above relationship (2), by setting Formula 1 "m < 2r ≤ g + l < n" and Formula 2 "r ≤ h ≤ (n - m)tan(180° - θ) - r", they are respectively used to restrict the horizontal position and vertical position of the positioning center on the protrusion, and the parameters "n" and "m" of the protrusion, the positioning area radius r, and the preset horizontal distance l are included in Formula 1 and 2. While meeting the requirement of the minimum installation distance between the two pipettes after splicing, the positioning center O of the positioning area 130 is set close to the median line a of the protrusion 110 to ensure that the occupied space of the positioning area 130 on the protrusion 110 is large enough, so that the pipette applying the housing 100 of the present application can be adapted to more types and sizes of liquid-taking tips 210 (refer to Figure 4 ) for installation, improving the applicability of the pipette applying the housing 100 of the present application.

[0055] When the protrusion 110 and the positioning center O simultaneously satisfy the relationships (1) and (2), it can further meet the requirements such as compactness, high throughput, minimum installation distance, and applicability of the pipette after splicing, and further improve the impact resistance of the protrusion 110, so that the durability and stability of the housing 100 are further improved, and further improve the service performance of the housing 100 of the present application.

[0056] In some embodiments, the preset horizontal distance l is the set distance between the positioning center O and the inclined surface 111.

[0057] Further, refer to Figures 1 to 3, the preset horizontal distance l can be obtained by setting in the following manner. Specifically, in order to ensure that the two pipettes can work independently and accurately after splicing, and to avoid cross-contamination, liquid residue or bubble generation, the horizontal distance between the positioning centers O on the two pipettes after splicing is set to k, that is, the minimum installation spacing is k; and in order to ensure the smoothness and flexibility of the two pipettes when they move separately after splicing, and to reduce the mutual collision of the shells 100 on the two pipettes after splicing and the influence of the processing accuracy of the shells 100, the installation gap between the protrusion 110 on one shell 100 and the protrusion 110 on the other shell 100 after splicing is set to d. Among them, the preset horizontal distance l, the minimum installation spacing k, and the installation gap d satisfy the following relationship:

[0058]

[0059] The relationship is used to calculate the preset horizontal distance from the positioning center O in each pipette to the inclined surface 111 as l, so that in actual application, after the two pipettes are spliced, the horizontal distance between the positioning centers O on the two pipettes is k.

[0060] Furthermore, the above-mentioned minimum installation spacing k satisfies the following relationship: k≤9mm.

[0061] Optionally, the value range of the above-mentioned minimum installation spacing k is any one of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, and 9mm, or a range formed by any two of them.

[0062] Further, see Figures 1 to 3 , the installation gap d satisfies the following relationship: d≥0mm. Specifically, in some embodiments, the installation gap d is equal to 0, so that the connection of the housing 100 on the two pipettes after splicing is more compact, and due to the setting of the inclined surface 111 on the protrusion 110, the protrusions 110 on the two pipettes can be in contact with each other. The impact on the independent sliding of the pipettes; in other embodiments, the installation gap d is greater than 0, and the specific value of the installation gap d can be determined based on the actual assembly requirements, and is not specifically limited here. In this way, the installation gap d is used to reserve sliding space for the sliding of the two pipettes after splicing, thereby improving the sliding smoothness of the two pipettes after splicing, and effectively avoiding the wear caused by the two protrusions 110 during sliding.

[0063] In some embodiments, see Figure 1 and Figure 2, the angle θ satisfies the following relationship: 90°<θ≤110°. Within this range, not only the connection area of ​​the protrusion 110 and the housing 100 can be increased, the connection strength between the two can be increased, and the protrusion 110 can be ensured to have a larger volume, so that the pipette using the housing 100 of the present application can be adapted to the installation of different liquid collection heads.

[0064] Optionally, the value of the angle θ is selected from a range formed by any one or two of 90°, 92°, 94°, 96°, 98°, 100°, 102°, 104°, 106°, 108°, and 110°.

[0065] In some embodiments, referring to FIG. Figure 2 , the protrusion 110 and the housing 100 satisfy the following relationship:

[0066]

[0067] Wherein, m is the width of the protrusion 110 away from the mounting surface 101 , n is the width of the protrusion 110 close to the mounting surface 101 , and c is the width of the housing 100 .

[0068] It can be understood that by setting “n>m”, the connection area between the protrusion 110 and the mounting surface 101 is made larger, thereby effectively improving the connection strength between the two and the impact resistance of the protrusion 110, thereby making the housing 100 more durable and stable; and by setting In the two connected pipettes, the mounting position 120 on the housing 100 of one pipette can completely accommodate the protrusion 110 on the housing 100 of the other pipette, thereby improving the compactness of the connection of the housings 100 of the two connected pipettes.

[0069] Further, see Figure 1 and Figure 2 , the width c of the above-mentioned shell 100 satisfies the following relationship: c≤17mm.

[0070] Optionally, the width c of the shell 100 may be in the range of 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, or 17 mm, or a range formed by any two of the above.

[0071] In some embodiments, see Figure 1 and Figure 2In the direction where the protrusion 110 is away from the installation position 120, the housing 100 is flush with the surface of the protrusion 110. In this way, in the direction where the protrusion 110 is away from the installation position 120, the protrusion 110 and the housing 100 form a flat surface, so as to improve the ease of installation when the housing 100 is subsequently installed.

[0072] In some embodiments, see Figure 1 and Figure 2 The shell 100 and the protrusion 110 are integrally formed to further enhance the connection strength between the two, thereby further enhancing the impact resistance of the protrusion 110 , and further enhancing the use stability of the shell 100 .

[0073] The technical solution of the housing 100 in the present application is clearly and completely described below.

[0074] In some embodiments, the housing 100 is an insulating housing.

[0075] Understandably, in the prior art, the housing 100 of the pipette is generally made of metal material, however, the housing 100 made of metal material will cause electromagnetic interference to the liquid level detection of the pipette, thereby resulting in low accuracy of the liquid level detection of the pipette. Based on this, in practical applications, when the insulating housing is applied to the pipette, the electronic components of the pipette can be arranged in the insulating housing, so that the electronic components are electromagnetically isolated from the outside of the insulating housing, thereby improving the detection accuracy of the pipette during liquid level detection.

[0076] Furthermore, the insulating shell may be formed by the shell 100 being made of an insulating material or by providing an insulating coating thereon; wherein the insulating material and / or the insulating coating may include but are not limited to at least one of plastic, ceramic material, glass, and the like.

[0077] In other embodiments, see Figure 1 and Figure 2 The housing 100 includes a first housing 140 and a second housing 150 connected to each other, wherein the first housing 140 is an insulating housing; wherein:

[0078] In this embodiment, the connection method between the main shell 100 and the first shell 140 includes but is not limited to at least one of screw connection, snap connection, plug connection, mortise and tenon connection, etc.

[0079] Further, see Figure 1 and Figure 2 , the hardness of the second shell 150 is greater than the hardness of the first shell 140.

[0080] It can be understood that after the shell 100 of the present application is applied to the pipette, the first shell 140 is arranged on the side close to the liquid collection end of the pipette, for the installation of electronic devices at the liquid collection end of the pipette (such as electronic devices for liquid level detection), and electromagnetic shielding is performed to avoid interference with the liquid level detection of the pipette, while the side away from the liquid collection end of the pipette adopts a second shell 150 with a greater hardness than the first shell 140 to ensure the overall structural strength of the shell 100, so as to further improve the performance of the shell 100.

[0081] Furthermore, the above-mentioned second shell 150 is made of metal material. The second shell 150 made of metal material not only has high structural strength and durability, but also has good thermal conductivity. When the pipette is applied with the shell 100 of the present application, the heat generated by the internal components of the pipette when working can be conducted to the outside through the second shell 150 made of metal material, thereby preventing the pipette from overheating, thereby improving the stability of the pipette.

[0082] Furthermore, the metal material of the second housing 150 includes but is not limited to aluminum, copper, alloy, etc.

[0083] Further, see Figure 1 and Figure 2 The first shell 140 and the second shell 150 both have the mounting surface 101, the protrusion 110 and the mounting position 120. The protrusion 110 on the first shell 140 is connected to the protrusion 110 on the second shell 150, and the mounting position 120 on the first shell 140 is connected to the mounting position 120 on the second shell 150.

[0084] It can be understood that when the shell 100 of the present application is applied to a pipette, in the two spliced ​​pipettes, the protrusion 110 of the first shell 140 and the protrusion 110 of the second shell 150 on one of the pipettes are respectively arranged in the mounting position 120 of the second shell 150 and the first shell 140 on the other pipette, and the protrusion 110 of the first shell 140 and the protrusion 110 of the second shell 150 on the other pipette are respectively arranged in the mounting position 120 of the second shell 150 and the first shell 140 on the one pipette, thereby ensuring the compactness of the connection between the shells 100 on the two pipettes.

[0085] For further information, see Figure 1 and Figure 2The protrusion 110 on the second shell 150 corresponds in shape to the protrusion 110 on the first shell 140, so that the protrusion 110 on the second shell 150 is connected to the protrusion 110 on the first shell 140 to form a continuous protrusion 110, and the mounting position 120 on the second shell 150 corresponds in shape to the mounting position 120 on the first shell 140, so that the mounting position 120 on the second shell 150 is connected to the mounting position 120 on the first shell 140 to form a continuous mounting position 120, thereby further improving the compactness of the splicing of the two pipette upper shells 100 after splicing.

[0086] Further, see Figure 1 and Figure 2 The second housing 150 is provided with a receiving notch 151, and the first housing 140 is installed in the receiving notch 151. It can be understood that the receiving notch 151 is provided on the second housing 150 to reserve space for the installation of the first housing 140, so as to facilitate the assembly and connection of the second housing 150 with the first housing 140.

[0087] Embodiment 2:

[0088] See also Figures 1 to 4 The embodiment of the present application also provides a pipette, comprising the housing 100 as described in the above embodiment 1.

[0089] In a pipette using the housing 100 of the first embodiment, the pipette includes internal components and external components, wherein the internal components are installed inside the housing 100, and the external components are installed outside the housing 100. The internal components include but are not limited to circuit boards, components, motor drive components, etc., and the external components include but are not limited to liquid collection gun tips 210, etc. The liquid collection gun tips 210 are installed on the protrusion 110 away from the mounting surface 101.

[0090] In practical applications, one side of the housing 100 on the pipette close to the inclined surface 111 is a mounting surface 101 adjacent to the inclined surface 111 of the protrusion 110. On one hand, the mounting surface 101 on the housing 100 is connected to the inclined surface 111 on the protrusion 110 to form a mounting position 120, which is used to reserve mounting space for the protrusion 110 on the housing 100 of the other pipette when two pipettes are spliced, so that the housings 100 on the two pipettes after splicing are more compactly connected, and it is easier to meet the minimum space between the two adjacent pipettes. Small installation spacing requirements reduce design difficulty; on the other hand, the installation surface 101 on the shell 100 is connected with the inclined surface 111 on the protrusion 110 to form an obtuse angle, so that the inclined surface 111 is inclined in the direction of the protrusion 110 away from the installation position 120. This structural arrangement increases the connection area between the protrusion 110 and the shell 100, improves the connection strength between the protrusion 110 and the shell 100, thereby improving the impact resistance of the protrusion 110, and further improves the stability of the shell 100 in the pipette.

[0091] For example, in the shell of the pipette, the side of the protrusion 110 away from the mounting surface 120 is used for the installation of the liquid collection gun tip 210. Due to the improved impact resistance of the protrusion 110, the protrusion 110 can withstand the impact force generated when the liquid collection gun tip 210 is installed to the liquid collection end of the pipette, thereby improving the durability and stability of the shell 100.

[0092] Embodiment three:

[0093] See also Figures 1 to 5 An embodiment of the present application provides a sample processing device, comprising a plurality of pipettes as described in Embodiment 2; among the plurality of pipettes, at least one is a first pipette 200A, and at least one is a second pipette 200B; the protrusion 110 of the first pipette 200A is arranged in the mounting position 120 of the second pipette 200B, and the protrusion 110 of the second pipette 200B is arranged in the mounting position 120 of the first pipette 200A.

[0094] It is understandable that the sample processing device of this embodiment includes multiple pipettes to meet the needs of high-throughput liquid detection. In addition, the side of the housing 100 on the pipette close to the inclined surface 111 is a mounting surface 101 adjacent to the inclined surface 111 of the protrusion 110. On one hand, the mounting surface 101 on the housing 100 is connected to the inclined surface 111 on the protrusion 110 to form a mounting position 120, which is used to reserve installation space for the protrusion 110 on the housing 100 of another pipette when two pipettes are spliced, so that the connection of the housings 100 on the two pipettes after splicing is more compact, and it is easier to meet the minimum installation space between two adjacent pipettes. Spacing requirements are met, reducing the design difficulty; on the other hand, the mounting surface 101 on the shell 100 is connected with the inclined surface 111 on the protrusion 110 to form an obtuse angle, so that the inclined surface 111 is inclined in the direction of the protrusion 110 away from the mounting position 120. This structural arrangement increases the connection area between the protrusion 110 and the shell 100, improves the connection strength between the protrusion 110 and the shell 100, thereby improving the impact resistance of the protrusion 110, and further improving the stability of the shell 100 when applied to the pipette.

[0095] For example, in the shell of the pipette, the side of the protrusion 110 away from the mounting surface 120 is used for the installation of the liquid collection gun tip 210. Due to the improved impact resistance of the protrusion 110, the protrusion 110 can withstand the impact force generated when the liquid collection gun tip 210 is installed to the liquid collection end of the pipette, thereby improving the durability and stability of the shell 100.

[0096] It can be seen that the shell 100 of the present application can meet the requirements of compactness, high throughput, and minimum installation spacing after the pipette is spliced. At the same time, due to the improved impact resistance of the protrusion 110, the shell 100 has stronger durability and stability, thereby improving the liquid handling performance of the pipette of the present application.

[0097] In some embodiments, see Figures 5 to 7 , the number of the first pipettes 200A is at least two, the number of the second pipettes 200B is at least two, and the first pipettes 200A and the second pipettes 200B are staggered and spliced ​​together; along the staggered splicing direction of the first pipettes 200A and the second pipettes 200B, the adjacent two first pipettes 200A and / or the adjacent two second pipettes 200B are symmetrically arranged or arranged in the same direction.

[0098] It can be understood that the first pipette 200A and the second pipette 200B of the present application are spliced ​​along the y direction to form a group of pipetting modules, that is, when the number of first pipettes 200A is at least two and the number of second pipettes 200B is at least two, the sample processing device includes multiple groups of pipetting modules, and each pipetting module is spliced ​​along the x direction to meet the needs of high-throughput pipetting detection.

[0099] Secondly, due to the structure of the pipette upper shell 100, after splicing, the "two adjacent first pipettes 200A" and / or "two adjacent second pipettes 200B" in the x-direction can be arranged in the same direction or symmetrically to meet different splicing requirements and the minimum installation spacing requirements between two adjacent pipettes, and can be spliced ​​with another set of pipette modules without distinguishing the orientation of the pipette modules, thereby improving the splicing efficiency.

[0100] Example: ① The first splicing method, see Figure 6 , Figure 6 The two adjacent first pipettes 200A / second pipettes 200B are arranged in the same direction in the x direction. It can be seen that the first pipette 200A and the second pipette 200B on the same group of pipette modules, as well as the first pipette 200A / second pipette 200B on one group of pipette modules and the second pipette 200B / first pipette 200A on another group of pipette modules all meet the minimum installation spacing k requirement between two adjacent pipettes.

[0101] ② The second splicing method, see Figure 7 , Figure 7The two adjacent first pipettes 200A / second pipettes 200B are symmetrically arranged in the x direction. It can be seen that the first pipette 200A and the second pipette 200B on the same group of pipette modules, as well as the first pipette 200A / second pipette 200B on one group of pipette modules and the second pipette 200B / first pipette 200A on another group of pipette modules all meet the requirement of the minimum installation spacing k between two adjacent pipettes.
