[0077] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0078] The liquid collection device provided in this application is used in equipment such as gene sequencers that generate waste liquid during use, for collecting the waste liquid. The liquid collection device of this application adopts a rotary structure, which occupies less space compared to a pull-out structure, and is beneficial to the miniaturization of the aforementioned equipment such as gene sequencers.

[0079] Please see Figure 1 The liquid collection device 100 of this application embodiment includes a compartment 1 and a compartment door 2 connected to each other. The compartment 1 and the compartment door 2 together enclose a receiving space 3. The receiving space 3 can be used to hold a waste liquid tank 200.

[0080] Please refer to the following: Figure 1 and Figure 2 The door 2 has a connecting end 210 and a free end 220. The connecting end 210 is rotatably connected to the compartment body 1, and the free end 220 forms an opening 221 for taking out and putting in. In this embodiment, the connecting end 210 is connected by a hinge 8 (see... Figure 3 The door 2 is rotatably connected to the compartment body 1. By pulling the free end 220 of the door 2, the door 2 can be rotated relative to the compartment body 1 around the connecting end 210. When the door 2 rotates away from the compartment body 1, the retrieval opening 221 is exposed; when the door 2 rotates towards the compartment body 1, the compartment body 1 closes the retrieval opening 221. Figure 1 The image shows the liquid collection device 100 in the off state. Figure 2 The image shows the liquid collection device 100 in its open state.

[0081] Please see Figure 3In this embodiment, the hopper 1 includes a back plate 110 and four side plates 120. The back plate 110 is a rectangular thin plate structure, and the four side plates 120 are respectively fixedly connected to the four sides of the back plate 110 and are perpendicular to the back plate 110.

[0082] The liquid collection device 100 also includes a nitrogen spring 4. One end of the nitrogen spring 4 is connected to the side plate 120 of the chamber 1, and the other end is connected to the chamber door 2. The nitrogen spring 4 is used to buffer the force during the rotation of the chamber door 2 relative to the chamber 1, preventing the chamber door 2 from impacting the chamber 1 forcefully or opening suddenly and causing liquid splashing. It can also be used to limit the opening angle of the chamber door 2 relative to the chamber 1. A mounting position 121 is also formed on the side plate 120 connected to the nitrogen spring 4 to accommodate the lid 201 of the waste liquid tank. During the operation of the equipment, the waste liquid tank is kept open. At this time, the lid 201 can be temporarily placed in the mounting position 121. When the waste liquid tank is removed, the lid 201 can be removed and screwed onto the waste liquid tank to prevent liquid splashing.

[0083] Please refer to the following: Figure 3 and Figure 4 The door 2 includes a front panel 230, a frame structure 250, and a weighing assembly 260. The front panel 230 has an inner surface 231 and an outer surface 232. When the door 2 is closed to the body 1, the inner surface 231 faces the accommodating space 3, and the outer surface 232 faces away from the accommodating space 3. The frame structure 250 is fixed to the inner surface 231 of the front panel 230, and the frame structure 250 and the front panel 230 together enclose a positioning cavity 270 that extends through both the upper (the end where the free end 220 is located) and the lower (the end where the connecting end 210 is located). The positioning cavity 270 is used to position the waste liquid tank 200 placed in the accommodating space 3. The loading / unloading opening 221 is connected to the upper end of the positioning cavity 270, so that the waste liquid tank placed in the accommodating space 3 through the loading / unloading opening 221 can enter the positioning cavity 270.

[0084] The weighing assembly 260 is located below the frame structure 250, specifically on the side of the frame structure 250 near the connecting end 210. The weighing assembly 260 includes a support plate 261, a positioning plate 263, and a weighing sensor 262 located between the support plate 261 and the positioning plate 263. The positioning plate 263 is fixedly connected to the inner surface 231 of the front plate 230. When the waste liquid tank is located within the positioning cavity 270, the bottom end of the waste liquid tank extends from the lower end of the positioning cavity 270 and rests on the support plate 261, and its weight can be sensed by the weighing sensor 262. This allows the determination of the waste liquid level in the waste liquid tank. By monitoring the sensing signal output by the weighing sensor 262, the waste liquid tank can be promptly removed and the waste liquid emptied when it is full. In this embodiment, the nitrogen spring 4 is connected to the frame structure 250.

[0085] Please refer to the following: Figure 5 , Figure 6 , Figure 7 and Figure 8 The liquid collection device 100 also includes an electromagnetic locking mechanism 5 for locking the chamber 1 and the door 2. In this embodiment, the electromagnetic locking mechanism 5 includes an electromagnetic latch 510, an electromagnetic locking shaft 520, and a mounting base 530. The electromagnetic latch 510 is fixedly connected to the free end 220 of the door 2 and to the side of the frame structure 250 facing the chamber 1. The back plate 110 has a first surface 111 facing the door 2 and a second surface 112 facing away from the door 2. The mounting base 530 is fixedly connected to the second surface 112, and the electromagnetic locking shaft 520 is movably connected to the mounting base 530. The electromagnetic latch 510 and the electromagnetic locking shaft 520 cooperate to lock the chamber 1 and the door 2, keeping the liquid collection device 100 in a closed state. The mounting base 530 has a built-in electromagnetic lock sensor for monitoring and feedback on the opening and closing status of the electromagnetic locking mechanism 5.

[0086] The electromagnetic latch 510 is a hollow annular structure, and the electromagnetic lock shaft 520 is a cylindrical elongated structure. The electromagnetic lock shaft 520 is controlled by an electrical signal to extend and retract in a straight line parallel to the second surface 112, so that one end extends out of or retracts into the mounting base 530. A first channel 113 is provided on the back plate 110, penetrating the first surface 111 and the second surface 112. The first channel 150 is located on the retraction path of the electromagnetic lock shaft 520. When the electromagnetic latch 510 extends out of the first channel 113, by controlling the electromagnetic lock shaft 520 to extend from the mounting base 530, one end of the electromagnetic lock shaft 520 can be inserted into the annular space of the electromagnetic latch 510, thereby locking the compartment 1 and the compartment door 2.

[0087] In this embodiment, after the waste liquid tank is placed into the accommodating space 3, the electromagnetic locking tongue 510 can be pushed out of the channel 150 by rotating the door 2. When the equipment used by the liquid collection device 100 enters the working state, an electrical signal can be output to control the electromagnetic locking shaft 520 to extend from the mounting base 530, locking the tank body 1 and the door 2, keeping the liquid collection device 100 in the closed state, and the waste liquid tank continuously collects and stores waste liquid during the operation of the equipment. When the equipment stops working, or when the waste liquid in the waste liquid tank is detected to reach a preset weight, an electrical signal can be output to control the electromagnetic locking shaft 520 to retract, unlocking the tank body 1 and the door 2. In this state, the liquid collection device 100 can be opened by pulling the door 2.

[0088] Please refer to this again. Figures 5 to 7The liquid collection device 100 also includes a latching mechanism 6 for locking the chamber body 1 and the chamber door 2. The latching mechanism 6 includes a male latch head 610 and a female latch head 620. The male latch head 610 is fixedly connected to the side of the frame structure 250 of the chamber door 2 facing the chamber body 1 and is spaced apart from the electromagnetic latch tongue 510. The female latch head 620 is connected to the second surface 112 of the back plate 110. A second channel 114 penetrating the first surface 111 and the second surface 112 is also provided on the back plate 110 at the position where the female latch head 620 is fixedly connected.

[0089] When the liquid collection device 100 is in the closed state, the male snap fastener 610 and the female snap fastener 620 engage with each other, locking the chamber 1 and the chamber door 2, keeping the chamber 1 closed and the access opening 221 closed. In this embodiment, the male snap fastener 610 has two symmetrically arranged slots 611 and 612. The female snap fastener 620 includes a mounting base 621 and two spherical telescopic structures 622 and 623 movably connected to the mounting base 621. The two telescopic structures 622 and 623 are spaced apart from each other. When the male snap fastener 610 and the female snap fastener 620 engage with each other, the male snap fastener 610 is engaged between the two telescopic structures 622 and 623, with the telescopic structure 622 located in the slot 611 and the telescopic structure 623 located in the slot 612.

[0090] When subjected to compressive force, the two telescopic structures 622 and 623 retract into the mounting base 621. When the compressive force is released, they spring back to their initial positions, protruding relative to the mounting base 621. Therefore, by pushing the free end 220 of the door 2 towards the side of the chamber 1, the male latch 610 can be pushed out from the second channel 114 between the telescopic structures 622 and 623. Continuing to push the door 2, the male latch 610 applies compressive force to both sides of the telescopic structures 622 and 623, causing them to retract into the mounting base 621. Continuing to push the door 2 until the telescopic structures 622 and 623 align with the slots 611 and 612 on the male latch 610, the telescopic structures 622 and 623 are no longer subjected to compressive force, spring back to their initial positions, and engage with the slots 611 and 612 respectively, locking the chamber 1 and the door 2, keeping the liquid collection device 100 in the closed state (see...). Figure 8 To open the liquid collection device 100, pull the door 2 away from the side of the chamber 1 to retract the telescopic structures 622 and 623, pulling the male latch 610 out from the female latch 620.

[0091] In this embodiment, the electromagnetic locking mechanism 5 and the snap-locking mechanism 6 are used to lock the chamber body 1 and the chamber door 2, specifically including:

[0092] Firstly, after placing the waste liquid container into the liquid collection device 100, push the free end 220 of the door 2 towards the direction of the container body 1 until the latching mechanism 6 locks. Before the equipment used by the liquid collection device 100 is powered on, the latching mechanism 6 locks the container body 1 and the door 2, keeping the liquid collection device 100 in a closed state. When the equipment used by the liquid collection device 100 is powered on and enters the working state, the electromagnetic locking shaft 520 in the electromagnetic locking mechanism 5 is extended. At this time, the electromagnetic locking mechanism 5 and the latching mechanism 6 together lock the container body 1 and the door 2. Thus, by setting the latching mechanism 6, before the aforementioned equipment is powered on, the latching mechanism 6 can be used to temporarily lock the container body 1 and the door 2, preventing the door 2 from opening.

[0093] Secondly, after the aforementioned equipment finishes operation, the system detects the completion of work and automatically opens the electromagnetic locking mechanism 5, causing the electromagnetic locking shaft 520 to retract into the mounting base 530. At this time, the snap-locking mechanism 6 locks the chamber body 1 and the chamber door 2 separately. If the snap-locking mechanism 6 is not locked to maintain the locking of the chamber body 1 and the chamber door 2, the chamber door 2 may open due to the gravity of the waste liquid tank, potentially causing the liquid in the waste liquid tank to spill out (the opening of the waste liquid tank is open when it is placed in the liquid collection device 100). Thus, by setting the snap-locking mechanism 6, spillage of the waste liquid tank after the equipment has finished operating can be prevented.

[0094] Please refer to the following: Figure 9 and Figure 10 The liquid collection device 100 also includes a conduit assembly 7 connected to the tank body 1. The conduit assembly 7 is used to convey waste liquid into the waste liquid tank. In this embodiment, the conduit assembly 7 has a standby position state and a working position state (see...). Figure 11 and Figure 12 The conduit assembly 7 can switch between the standby position and the working position. When the liquid collection device 100 is not filled with waste liquid, the conduit assembly 7 is in the standby position. When the waste liquid is filled with liquid collection device 100, the conduit assembly 7 switches to the working position.

[0095] In this embodiment, the conduit assembly 7 includes a waste liquid conduit 710, an electric actuator 720, a transmission component 730, a first photoelectric sensor 740, and a second photoelectric sensor 750. The electric actuator 720, the first photoelectric sensor 740, and the second photoelectric sensor 750 are respectively fixedly connected to the second surface 112 of the back plate 11. The transmission component 730 connects the electric actuator 720 and the waste liquid conduit 710. The waste liquid conduit 710 is movably connected to the back plate 11 and connected to the transmission component 730. The electric actuator 720 drives the transmission component 730 to rotate the waste liquid conduit 710 around its axis, thereby switching between a standby position and a working position. The first photoelectric sensor 740 and the second photoelectric sensor 750 are used to sense the position of the transmission component 730 to locate the position of the conduit assembly 7.

[0096] In this embodiment, the waste liquid conduit 710 has a connecting end 711 and a bent end 712. The waste liquid conduit 710 passes through the back plate 110, such that the connecting end 711 is connected to the transmission member 730, while the bent end 712 is located within the accommodating space 3. The electric actuator 720 includes a motor 721 and a push rod 722 connected to each other. The motor 721 drives the push rod 722 to extend and retract in a straight line direction parallel to the second surface 112. The transmission member 730 includes a connecting portion 731 and a baffle 732 fixedly connected to the connecting portion 731. The connecting portion 731 is connected to the connecting end 711 of the waste liquid conduit 710 and the push rod 722 of the electric actuator 720, respectively.

[0097] by Figure 9 Taking the direction as an example, Figure 9 The diagram shows the structure of the conduit assembly 7 in the standby position. At this time, the baffle 732 of the transmission component 730 is located between the light emitting end and the light receiving end of the first photoelectric sensor 740, blocking the light transmission channel of the first photoelectric sensor 740. When the first photoelectric sensor 740 senses that the light receiving end cannot receive a light signal, it can determine that the conduit assembly 7 is in the standby position.

[0098] When motor 721 drives push rod 722 to extend to the right, push rod 722 drives transmission component 730 to rotate counterclockwise. Transmission component 730 drives waste liquid conduit 710 to rotate counterclockwise around an axis perpendicular to back plate 110 until the baffle 732 of transmission component 730 is positioned between the light emitting end and the light receiving end of second photoelectric sensor 750, blocking the light transmission channel of second photoelectric sensor 750. Figure 11 and Figure 12As shown. When the second photoelectric sensor 750 detects that the light receiver cannot receive a light signal, it can determine that the conduit assembly 7 is in the working position, and the motor 721 stops driving the push rod 722 to move linearly to the right. When the conduit assembly 7 is in the working position, the bent end 712 of the waste liquid conduit 710 is screwed into the waste liquid tank 200 from the tank opening 202, so that subsequent equipment can transport waste liquid into the waste liquid tank 200 during operation.

[0099] After the equipment finishes working, or when the waste liquid in the waste liquid tank 200 reaches the preset weight, the conduit assembly 7 is connected from... Figure 11 and Figure 12 The working position status shown has been switched to Figure 9 and Figure 10 In the standby working state shown, during the switching process, the motor 721 drives the push rod 722 to retract to the left. The push rod 722 drives the transmission component 730 to rotate clockwise. The transmission component 730 drives the waste liquid conduit 710 to rotate clockwise around an axis perpendicular to the back plate 110 until the baffle 732 of the transmission component 730 is located between the light emitting end and the light receiving end of the first photoelectric sensor 740. At this time, the waste liquid conduit 710 is pulled out from the barrel opening 202 of the waste liquid barrel 200.

[0100] Therefore, in the liquid collection device 100 of this application embodiment, the door 2 is rotatably connected to the body 1, so that pulling the door 2 to rotate it relative to the body 1 by a small angle can open the accommodating space 3 to retrieve or place the waste liquid container 200. Compared to a pull-out structure, the liquid collection device 100 of this application embodiment adopts a rotary structure, which occupies less space. When the liquid collection device 100 is applied to equipment that generates waste liquid, such as gene sequencers, it is beneficial to the miniaturization of such equipment.

[0101] Furthermore, the liquid collection device 100 in this application embodiment includes an electromagnetic locking mechanism 5 and a snap-locking mechanism 6 to lock the chamber body 1 and the chamber door 2 together, which can prevent the chamber door 2 from being opened accidentally and help to avoid waste liquid spillage.

[0102] In addition, the liquid collection device 100 of this application embodiment also includes a conduit assembly 7. By switching the conduit assembly 7 between the standby position state and the working position state, it can flexibly cooperate with the process of picking up and putting down the waste liquid tank.

[0103] Those skilled in the art should recognize that the above embodiments are only used to illustrate this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of protection claimed by this application.
