Description

Technical Field

[0001] This invention relates to the field of biochemical reaction equipment, and more specifically, to a waste liquid collection device. Background Technology

[0002] For devices or machines that typically involve fluid biochemical reactions and require the collection of liquid (or waste liquid) (or devices or machines that discharge liquid outside the machine during operation), many directly discharge the liquid into an external container. This introduces various unknown risks, such as excessive liquid (or waste liquid) discharge overflowing the external container. While a liquid level sensor could be installed on the machine, communication between the sensor and the machine is subject to various uncertainties: such as difficulty in sensor installation, user damage, sensor corrosion by waste liquid, container accumulating dirt and odor over time requiring replacement, and the high cost of replacing a container with one equipped with a sensor.

[0003] Therefore, placing a waste liquid collection container (hereinafter referred to as a waste liquid tank) and a non-contact liquid level detection sensor inside the machine is a good option. At the same time, inserting the waste liquid drain pipe or needle into the opening of the waste liquid tank can prevent waste liquid from splashing outside the tank, ensuring the cleanliness of the machine's interior and reducing corrosion of internal components.

[0004] To insert the waste liquid needle into the waste liquid container, the user needs to perform two actions: first, align the container with the opening of the waste liquid needle, and then move the needle into the opening of the waste liquid container; alternatively, the waste liquid needle and the waste liquid container can be moved simultaneously, allowing the waste liquid needle to extend into the opening of the waste liquid container, but this method has high requirements for machine space and reliability, and is complex to operate. Summary of the Invention

[0005] The main objective of this invention is to provide a waste liquid collection device to solve the problem of complicated operation in related technologies, which involves placing the waste liquid needle into the waste liquid tank or removing the waste liquid needle from the waste liquid tank.

[0006] To achieve the above objectives, the present invention provides a waste liquid collection device, comprising: a housing; a waste liquid tank disposed within the housing; a rotating door, one edge of which is rotatably connected to the housing and having a closed position that covers the waste liquid tank and an open position that exposes the waste liquid tank; and a waste liquid needle assembly disposed within the housing, the waste liquid needle assembly comprising a base, a retractable waste liquid needle disposed on the base, and a driving member, the waste liquid needle having an extended position that extends into the waste liquid tank and a retracted position that disengages from the waste liquid tank, the rotating door and the driving member drivingly cooperating to drive the waste liquid needle to move between the extended position and the retracted position.

[0007] Furthermore, the driving component includes a drive rod telescopically disposed on the base and a first elastic reset member disposed between the base and the waste liquid needle. The first elastic reset member enables the waste liquid needle to move from the extended position to the retracted position. The first end of the drive rod can extend out of the base and abut against the rotating door, and the second end of the drive rod can abut against the upper end of the waste liquid needle to drive the waste liquid needle to move from the retracted position to the extended position.

[0008] Furthermore, an inclined structure is provided between the second end of the drive rod and the upper end of the waste liquid needle. The inclined structure includes a first driving inclined part provided at the second end of the drive rod and a second driving inclined part provided at the upper end of the waste liquid needle. The first driving inclined part and the second driving inclined part abut against each other.

[0009] Furthermore, the seat body has a receiving cavity and a first guide hole and a second guide hole communicating with the receiving cavity. The waste liquid needle passes through the first guide hole, the second driving inclined part is disposed in the receiving cavity, the driving rod passes through the second guide hole, and the first driving inclined part is disposed in the receiving cavity and cooperates with the cavity wall of the receiving cavity.

[0010] Furthermore, the first elastic reset member is sleeved on the waste liquid needle and abuts against the wall of the second driving inclined part and the cavity of the receiving cavity respectively to apply an upward elastic force to the second driving inclined part. The waste liquid needle assembly also includes a second elastic reset member, which abuts against the wall of the first driving inclined part and the cavity of the receiving cavity respectively to apply an elastic force toward the rotating door to the first driving inclined part.

[0011] Furthermore, the second drive inclined surface is provided with a mounting hole that communicates with the inner hole of the waste liquid needle, and the waste liquid delivery pipe communicates with the waste liquid needle through the mounting hole.

[0012] Furthermore, the waste liquid collection device also includes a receiving tank disposed within the housing, the waste liquid tank being disposed within the receiving tank and the receiving tank being rotatably connected to the housing.

[0013] Furthermore, the waste liquid collection device also includes a linkage assembly, which includes a linkage rod hinged between the rotating door and the receiving tank.

[0014] Furthermore, the linkage assembly also includes a torsion spring, a first pin disposed on the rotating door, and a second pin disposed on the receiving box. The two ends of the torsion spring are respectively engaged with the rotating door and the receiving box. The first pin passes through the first end of the linkage rod, and the second end of the linkage rod is provided with a groove, in which the second pin passes.

[0015] Furthermore, the rotating door is provided with a limiting component, the limiting component has a limiting hole, and the housing is provided with a limiting rod. When the rotating door is in the closed position, the limiting rod extends into the limiting hole, keeping the rotating door in the closed position; and / or, the waste liquid collection device also includes a liquid level detection device provided on the rear side of the housing, the liquid level detection device is used to detect the liquid level in the waste liquid tank; and / or, the receiving tank is provided with a positioning detection component, the rear side of the housing is provided with a positioning sensor, and the housing is provided with a strip-shaped through hole, the positioning detection component passes through the strip-shaped through hole and engages with the positioning sensor.

[0016] By applying the technical solution of this invention, a rotating door is installed on the waste liquid collection device to shield the waste liquid tank, preventing the tank and waste liquid delivery pipes from being directly exposed. A retractable waste liquid needle is installed within the base. When waste liquid needs to be discharged, the needle extends to the extended position for discharge; after discharge, the needle moves from the extended to the retracted position, facilitating the user to remove the waste liquid tank for subsequent emptying. The rotating door, in conjunction with a drive mechanism, moves the waste liquid needle between the extended and retracted positions. The drive mechanism ensures that the user's action of opening or closing the rotating door corresponds to the extension or retraction of the waste liquid needle; that is, when the user opens the rotating door, the needle retracts; when the user closes the rotating door, the needle extends. This eliminates the need for the user to manually place or remove the needle from the waste liquid tank, simplifying the process. Therefore, the technical solution of this application can effectively solve the problem of complicated operation in related technologies, such as putting waste liquid needles into waste liquid bins or taking waste liquid needles out of waste liquid bins.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] like Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 12 As shown, the waste liquid collection device of this embodiment includes: a housing 10, a waste liquid tank 20, a rotating door 30, and a waste liquid needle assembly 40. The waste liquid tank 20 is disposed within the housing 10; one edge of the rotating door 30 is rotatably connected to the housing 10 and has a closed position that covers the waste liquid tank 20 and an open position that exposes the waste liquid tank 20; the waste liquid needle assembly 40 is disposed within the housing 10 and includes a base 41, a retractable waste liquid needle 42 disposed on the base 41, and a driving member 43. The waste liquid needle 42 has an extended position that extends into the waste liquid tank 20 and a retracted position that disengages from the waste liquid tank 20. The rotating door 30 and the driving member 43 are driven together to move the waste liquid needle 42 between the extended and retracted positions.

[0041] By applying the technical solution of this embodiment, a rotating door 30 is provided on the waste liquid collection device to cover the waste liquid tank 20, preventing the waste liquid tank 20 and waste liquid conveying pipe from being directly exposed. The waste liquid needle 42 is retractably installed inside the base 41. When waste liquid needs to be discharged, the waste liquid needle 42 is in the extended position to perform the discharge operation; after the waste liquid discharge is completed, the waste liquid needle 42 is moved from the extended position to the retracted position, making it convenient for the user to remove the waste liquid tank 20 for subsequent operations such as emptying the waste liquid in the waste liquid tank 20. The rotating door 30 and the driving component 43 work together to move the waste liquid needle 42 between an extended position and a retracted position. The driving component 43 is configured so that the user's action of opening or closing the rotating door 30 corresponds to the extension or retraction of the waste liquid needle 42. That is, when the user opens the rotating door 30, the waste liquid needle 42 retracts; when the user closes the rotating door 30, the waste liquid needle 42 extends. This eliminates the need for the user to manually place or remove the waste liquid needle 42 from the waste liquid tank 20, making it more convenient for the user. Therefore, the technical solution of this embodiment effectively solves the problem of complex operations in related technologies, such as placing or removing the waste liquid needle from the waste liquid tank.

[0042] It should be noted that the "retracted position" mentioned above is relative to the extended position. When the waste liquid needle 42 is in the retracted position, the waste liquid needle 42 can be completely retracted into the seat 41 or partially extended out of the seat 41. However, the extension length of the waste liquid needle 42 in the retracted position is smaller than the extension length of the waste liquid needle 42 in the extended position.

[0043] Specifically, in this embodiment, the waste liquid needle 42 is positioned directly opposite the bottle opening of the waste liquid tank 20. A sealing membrane is provided at the bottle opening of the waste liquid tank 20. When the waste liquid needle 42 moves downward, it can pass through the sealing membrane, which can reduce the odor caused by the evaporation of waste liquid.

[0044] like Figure 1 , Figure 2 as well as Figures 4 to 6 As shown, the driving member 43 includes a driving rod 431 that is telescopically disposed on the base 41 and a first elastic reset member 432 disposed between the base 41 and the waste liquid needle 42. The first elastic reset member 432 can move the waste liquid needle 42 from the extended position to the retracted position. The first end of the driving rod 431 can extend out of the base 41 and abut against the rotating door 30. The second end of the driving rod 431 can abut against the upper end of the waste liquid needle 42 to drive the waste liquid needle 42 from the retracted position to the extended position. When the user closes the revolving door 30, the revolving door 30 pushes the drive rod 431, causing the drive rod 431 to move backward. As the drive rod 431 moves backward, it pushes the waste liquid needle 42 downward, compressing the first elastic reset member 432. The waste liquid needle 42 then moves downward and extends into the waste liquid tank 20. When the user opens the revolving door 30, the revolving door 30 releases the pushing force on the drive rod 431. The first elastic reset member 432 applies an upward elastic force to the waste liquid needle 42, causing the waste liquid needle 42 to move upward and push the drive rod 431, causing the drive rod 431 to move forward. This structure has the advantages of simple structure and reliable drive.

[0045] like Figure 5 as well as Figure 15 As shown, in this embodiment, an inclined structure 44 is provided between the second end of the drive rod 431 and the upper end of the waste liquid needle 42. The inclined structure 44 includes a first driving inclined portion 441 provided at the second end of the drive rod 431 and a second driving inclined portion 442 provided at the upper end of the waste liquid needle 42. The first driving inclined portion 441 and the second driving inclined portion 442 abut against each other. By providing the first driving inclined portion 441 and the second driving inclined portion 442, the lateral movement of the drive rod 431 is converted into the vertical movement of the waste liquid needle 42, or the vertical movement of the waste liquid needle 42 is converted into the lateral movement of the drive rod 431, which has the advantages of simple structure and reliable drive.

[0046] like Figure 5 as well as Figure 15 As shown, in this embodiment, the seat 41 has a receiving cavity 411 and a first guide hole 412 and a second guide hole communicating with the receiving cavity 411. The waste liquid needle 42 passes through the first guide hole 412, the second driving inclined part 442 is disposed in the receiving cavity 411, and the driving rod 431 passes through the second guide hole. The first driving inclined part 441 is disposed in the receiving cavity 411 and stops in cooperation with the cavity wall of the receiving cavity 411. The first guide hole 412 can guide the movement of the waste liquid needle 42; the second guide hole can guide the driving member 43 and stop the first driving inclined part 441, ensuring the reliability of the movement of the waste liquid needle 42 and the driving member 43.

[0047] like Figure 5 , Figure 7 as well as Figure 15 As shown, in this embodiment, the first elastic reset member 432 is sleeved on the waste liquid needle 42 and abuts against the walls of the second driving inclined portion 442 and the receiving cavity 411 respectively to apply an upward elastic force to the second driving inclined portion 442. The waste liquid needle assembly 40 also includes a second elastic reset member 45, which abuts against the walls of the first driving inclined portion 441 and the receiving cavity 411 respectively to apply an elastic force toward the rotating door 30 to the first driving inclined portion 441. The first elastic reset member 432 is sleeved on the waste liquid needle 42, and the waste liquid needle 42 can limit the first elastic reset member 432. The waste liquid needle assembly 40 also includes the second elastic reset member 45. When the user opens the rotating door 30, the second elastic reset member 45 can apply a forward elastic force toward the first driving inclined portion 441, making it easier for the waste liquid needle 42 to move from the extended position to the retracted position.

[0048] like Figure 5 , Figure 6 as well as Figure 15 As shown, the second drive inclined surface 442 is provided with a mounting hole 4421 communicating with the inner hole 421 of the waste liquid needle 42. The waste liquid delivery pipe communicates with the waste liquid needle 42 through the mounting hole 4421. Correspondingly, the base 41 and the housing 10 are provided with through holes for the waste liquid delivery pipe to extend into. The user only needs to insert the head of the waste liquid delivery pipe into the mounting hole 4421 to perform the subsequent waste liquid discharge action, simplifying the user's operation and making it more convenient for the user. At the same time, the waste liquid is directly discharged into the waste liquid tank 20 through the waste liquid delivery pipe and the waste liquid needle 42. During the waste liquid discharge process, the waste liquid will not splash out or flow outside the waste liquid tank 20, ensuring cleanliness during the waste liquid discharge process and effectively improving the user experience. In addition, the design of this embodiment makes the wiring of the waste liquid delivery pipe simpler and not exposed, reducing the risk of tripping and ensuring the safety of the user during use.

[0049] like Figure 2 , Figures 11 to 14 As shown, the waste liquid collection device also includes a receiving box 50 disposed within the housing 10, with a waste liquid tank 20 disposed within the receiving box 50. The receiving box 50 is rotatably connected to the housing 10. Because the receiving box 50 is rotatably connected to the housing 10, after the user opens the rotating door 30, the receiving box 50 can be rotated so that the handle of the waste liquid tank 20 faces the user, making it easier for the user to grasp the handle and remove the waste liquid tank 20. Simultaneously, rotating the receiving box 50 at a certain angle ensures that the top wall of the housing 10 will not obstruct the waste liquid tank 20 when the user removes it, making the removal process smoother and more convenient for the user.

[0050] like Figure 11 , Figure 16 and Figure 17 As shown, the waste liquid collection device also includes a linkage component 60, which includes a linkage rod 61 hinged between the rotating door 30 and the receiving tank 50. Because the linkage rod 61 is hinged to the receiving tank 50, the receiving tank 50 will rotate along with the rotating door 30 when the user opens or closes the rotating door 30, further facilitating user operation.

[0051] In this embodiment, the pivot axis between the rotating door 30 and the housing 10 and the pivot axis between the receiving box 50 and the housing 10 are spaced apart, which makes the dimensions of the rotating door 30 and the receiving box 50 more reasonable. Of course, in an embodiment not shown in the figure, the pivot axis between the rotating door and the housing and the pivot axis between the receiving box and the housing can also be set coaxially, which allows the rotating door and the receiving box to rotate synchronously, making it less likely to jam and ensuring the smooth movement of the rotating door and the receiving box.

[0052] like Figure 11 , Figure 16 and Figure 17 As shown, in this embodiment, the linkage component 60 further includes a torsion spring 62, a first pin disposed on the rotating door 30, and a second pin disposed on the receiving box 50. The two ends of the torsion spring 62 abut against the rotating door 30 and the receiving box 50, respectively. The first pin passes through the first end of the linkage rod 61, and the second end of the linkage rod 61 is provided with a sliding groove 611, in which the second pin passes. When the user opens the rotating door 30, the receiving box 50 is first pressed into a vertical position by the pressure of the torsion spring 62. At the same time, due to the presence of the sliding groove 611, only the rotating door 30 rotates while the receiving box 50 remains in a vertical position. When the rotating door 30 is opened to a certain angle, the waste liquid needle 42 has completely detached from the waste liquid tank 20, and the second pin abuts against the upper end of the sliding groove 611, causing the rotating door 30 to rotate together with the receiving box 50. Similarly, when the user closes the rotating door 30, due to the presence of the torsion spring 62 of the slide 611, the waste liquid tank 20 will first rotate from the inclined position to the vertical position, and then the rotating door 30 will drive the waste liquid needle 42 to extend into the waste liquid tank 20.

[0053] like Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 16 as well as Figure 17As shown, in this embodiment, a positioning detection element 71 is provided on the housing 50, and a positioning sensor 72 is provided on the rear side of the housing 10. A strip-shaped through hole 11 is provided on the housing 10, through which the positioning detection element 71 passes and engages with the positioning sensor 72. The positioning sensor 72 is connected to a controller that controls the biochemical reaction. The corresponding biochemical reaction can only proceed after the positioning sensor 72 senses the positioning detection element 71 (i.e., after the waste liquid tank 20 is in a vertical position). This avoids the situation where waste liquid starts to flow out of the waste liquid tank 20 before it is in position.

[0054] like Figures 10 to 13 As shown, a limiting member 81 is provided on the rotating door 30, and a limiting hole 811 is provided on the limiting member 81. A limiting rod 82 is provided inside the housing 10. When the rotating door 30 is in the closed position, the limiting rod 82 extends into the limiting hole 811, keeping the rotating door 30 in the closed position. Because of the torsion spring 62, the rotating door 30 cannot automatically remain in the closed position. By providing a limiting member 81 on the rotating door 30 and a limiting rod 82 inside the housing 10, when the rotating door 30 is in the closed position, the limiting rod 82 extends into the limiting hole 811 to overcome the pressure of the torsion spring 62, thus keeping the rotating door 30 in the closed position. Specifically, in this embodiment, the limiting rod 82 is an electric push rod.

[0055] like Figure 3 , Figure 8 as well as Figure 17 As shown, the waste liquid collection device also includes a liquid level detection device 90 located on the rear side of the housing 10. The liquid level detection device 90 is used to detect the liquid level in the waste liquid tank 20. The liquid level detection device 90 is a non-contact detection device (specifically, it can be a capacitive sensor). Setting the liquid level detection device 90 in the housing 10 avoids the need to set a corresponding liquid level detection element in the waste liquid tank 20. The liquid level detection device 90 is not corroded by the waste liquid, which can better ensure its service life and stability, and effectively avoid the problem of high cost caused by frequent replacement of liquid level detection elements.

[0056] Using the technical solution of this embodiment, the waste liquid tank 20 is set inside the waste liquid collection device. The entire biochemical reaction equipment has no external pipelines, making it very simple and preventing users from accidentally operating it or tripping over the pipelines and overturning the waste liquid tank 20. The liquid level detection device 90 is set outside the housing 10. The waste liquid flows directly into the waste liquid tank 20 through the waste liquid delivery pipe and the waste liquid needle 42. The waste liquid needle 42 is suspended above the highest liquid level of the waste liquid and is located inside the waste liquid tank 20. The waste liquid does not directly contact the waste liquid needle 42 or the liquid level detection device 90, so there is no waste liquid spillage. The user operation is simple and convenient, and there is no waste liquid dripping into the machine, eliminating the risk of waste liquid corroding the machine.

[0057] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0058] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0059] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
