[0033] See also Figures 1 to 3In some optional embodiments, the present application provides a trash bin device, which includes a frame mechanism 1 and a trash bin mechanism 4. In addition to the above-mentioned components, the trash bin device may also include a discarding pipe mechanism 2 and / or an upper cover mechanism 3. Discarded garbage can be transported to the trash bin mechanism 4 through the discarding pipe mechanism 2, wherein the garbage can be a test tube or other garbage that needs to be discarded. The frame mechanism 1 has a garbage receiving position 101 and a garbage unloading position 102. The trash bin mechanism 4 includes a box assembly 4200 and a sealing assembly 4400. The box assembly 4200 is movably mounted on the frame mechanism 1 and can move between the garbage receiving position 101 and the garbage unloading position 102. The box assembly 4200 can receive garbage discharged from the discarding pipe mechanism 2 when in the garbage receiving position 101, and can unload garbage when in the garbage unloading position 102. The box assembly 4200 includes an inner box 4205 for mounting a garbage bag, and a sealing assembly 4400 mounted on the inner box 4205 to seal the opening of the garbage bag. The inner box 4205 has a chamber for mounting a garbage bag. When mounting the garbage bag, the garbage bag can be inserted into the inner box 4205 to cover the walls of the chamber. The opening of the garbage bag is bent outward to form a flange, which covers the top of the outer box 4202 and is hooked on the top of the outer box 4202. This allows the opening of the garbage bag to remain stably open, facilitating the smooth falling of garbage into the garbage bag. The sealing assembly 4400 can be mounted on the inside of the chamber, that is, between the inner box 4205 and the garbage bag, so that the sealing assembly 4400 tightens the opening of the garbage bag.

[0034] Optionally, the discard pipe mechanism 2 includes a discard pipe 201 for discharging garbage into a garbage bag installed on the inner box 4205. The outlet of the discard pipe 201 can correspond to the box opening of the inner box 4205 when the box assembly 4200 is located at the garbage receiving position 101. Figure 3 The discarding pipe 201 can be a straight pipe and arranged vertically, making it less likely for garbage to get stuck while sliding within the discarding pipe 201. Furthermore, the entrance 202 of the discarding pipe 201 is trumpet-shaped, which reduces the difficulty for garbage to enter the entrance 202. This is particularly helpful when the garbage is a test tube, as it helps reduce the risk of the test tube being unable to enter the entrance 202 due to tail deflection. Furthermore, the discarding pipe mechanism 2 also includes a through-beam detection optical coupler 203, which is installed on the discarding pipe 201 to detect whether the garbage is discharged from the outlet of the discarding pipe 201. Specifically, the through-beam detection optical coupler 203 is installed near the outlet of the discarding pipe 201, which helps improve the accuracy of detection.

[0035] Optionally, the upper cover mechanism 3 is mounted on the frame mechanism 1 and is located above the trash bin mechanism 4. The upper cover mechanism 3 includes an upper cover plate 301 and a reflection detection optical coupler 302. The upper cover plate 301 is adapted to cover the opening of the inner box 4205 when the box assembly 4200 is located at the trash receiving position 101, thereby sealing the inner box 4205 and reducing the risk of contaminant leakage. The reflection detection optical coupler 302 is mounted on the upper cover plate 301 and is used to detect the total amount of trash in the inner box 4205. Furthermore, a discard pipe 201 is mounted on the upper cover plate 301. The outlet end of the discard pipe 201 passes through the upper cover plate 301 so as to align with the opening of the inner box 4205 when the box assembly 4200 is located at the trash receiving position 101. The opening of the trash bag faces the outlet of the discard pipe 201, so that the trash discharged from the outlet of the discard pipe 201 directly falls into the trash bag mounted on the inner box 4205. Furthermore, there are multiple reflection detection optocouplers 302, and the multiple reflection detection optocouplers 302 are distributed at different positions of the upper cover 301, so as to detect the amount of garbage at different positions in the inner box 4205, avoid the local stacking of garbage in the inner box 4205 and misjudge the full load, and improve the accuracy of detection; specifically, there are two reflection detection optocouplers 302, and the outlet of the discard pipe 201 is located between the two reflection detection optocouplers 302.

[0036] Optionally, the upper cover mechanism 3 also includes an ultraviolet disinfection lamp 303, which is installed on the upper cover plate 301 and can be turned on when the box assembly 4200 is in the garbage receiving position 101 to disinfect the garbage in the inner box 4205. Furthermore, the ultraviolet disinfection lamp 303 can be installed in the middle of the upper cover plate 301, which is conducive to fully irradiating various areas of the inner box 4205, thereby improving the disinfection effect. When the inner box 4205 arrives at the garbage receiving position 101, the ultraviolet disinfection lamp 303 is turned on to disinfect the discarded garbage in real time. When the reflection detection optical coupler 302 detects that the inner box 4205 is full of garbage, the inner box 4205 moves to the garbage unloading position 102, and the ultraviolet disinfection lamp 303 is turned off.

[0037] In the garbage bin device of the above embodiment, the box assembly 4200 is movably mounted on the frame mechanism 1, and can be moved and switched between the garbage receiving position 101 and the garbage unloading position 102 under the action of external force. When the garbage in the inner box 4205 of the box assembly 4200 is at the garbage receiving position 101, it can be in a closed space under the action of the upper cover 301. When the garbage in the inner box 4205 is at the garbage unloading position 102, the bag opening of the garbage bag can be sealed by the sealing assembly 4400 so that the garbage is also in a closed space, and the pollution source is not easily exposed. In addition, by setting the sealing assembly 4400 to achieve the sealing of the bag opening of the garbage bag, the risk of contact between the operator and the garbage is effectively reduced, thereby reducing the risk of biological infection.

[0038] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In some optional embodiments, the box assembly 4200 further includes an outer box 4202 and a negative pressure fan 4201. The outer box 4202 is hermetically mounted on the inner box 4205. A negative pressure zone is formed between the inner wall of the outer box 4202 and the outer wall of the inner box 4205. The negative pressure zone is connected to the chamber of the inner box 4205 for installing the garbage bag. The negative pressure fan 4201 is used to extract air from the negative pressure zone to place the negative pressure zone in a negative pressure state, thereby placing the chamber of the inner box 4205 in a negative pressure state, thereby allowing the garbage bag to be adsorbed on the cavity wall of the chamber. The box assembly 4200 is provided with an air duct so that the negative pressure zone can form a negative pressure environment under the action of the negative pressure fan 4201.

[0039] Optionally, the box assembly 4200 further includes a sealing upper cover 4203 , and the inner box 4205 is installed in the outer box 4202 . The sealing upper cover 4203 covers the opening of the negative pressure area, so that the negative pressure area can be in a sealed state.

[0040] Optionally, the box assembly 4200 further includes a first detection optical coupler 4204 and a pressure cover 4207. The first detection optical coupler 4204 is mounted on the inner box 4205 and is used to detect whether the garbage bag is properly installed. The pressure cover 4207 is used to compress the garbage bag and is provided with a pressure sensor 4206 for detecting whether the pressure cover 4207 is properly pressed. There can be multiple first detection optical couplers 4204 evenly distributed around the inner box 4205 to accurately detect whether the garbage bag is properly installed. The pressure cover 4207 can be a frame structure that matches the shape of the box opening of the inner box 4205 to fully compress the garbage bag. Specifically, the garbage bag is put into the inner box body 4205, the upper edge of the garbage bag is folded over and put on the edge of the box opening of the inner box body 4205, and the upper edge of the garbage bag is pressed tightly by the pressure cover 4207 to fix the garbage bag. When the first detection optical coupler 4204 and the pressure sensor 4206 both detect signals, the negative pressure fan 4201 starts to operate, and the negative pressure area forms a negative pressure environment, so that the garbage bag is adsorbed to the inner wall of the inner box body 4205.

[0041] Optionally, the box assembly 4200 further includes an indicator light 4208, which can be installed on the sealing upper cover 4203. The indicator light 4208 displays whether the first detection optical coupler 4204 and / or the pressure sensor 4206 detects a signal, making observation simple and convenient.

[0042] In the garbage bin assembly device of the above embodiment, the outer box body 4202, the inner box body 4205 and the negative pressure fan 4201 cooperate to allow the garbage bag to be adsorbed on the inner box body 4205. On the one hand, it is convenient for the installation, fixation and shaping of the garbage bag, and on the other hand, it reduces the requirements for the type of garbage bag. Conventional garbage bags on the market can meet the usage requirements, and there is no need to customize garbage bags, which is conducive to reducing costs.

[0043] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In some optional embodiments, the trash bin mechanism 4 further includes a driving component 4100, the frame mechanism 1 has a shaking detection position 103, the driving component 4100 is connected to the box component 4200 and drives the box component 4200 to move back and forth between the shaking detection position 103 and the garbage receiving position 101 to vibrate and mix the garbage in the inner box 4205, which helps to prevent the garbage in the inner box 4205 from being partially stacked into a hill shape in the box.

[0044] Optionally, the shaking detection position 103, the garbage receiving position 101, and the garbage unloading position 102 are sequentially located along the same movement path, and the drive assembly 4100 drives the box assembly 4200 to move between the shaking detection position 103, the garbage receiving position 101, and the garbage unloading position 102; wherein the movement path of the shaking detection position 103, the garbage receiving position 101, and the garbage unloading position 102 is a linear movement path, and the shaking detection position 103, the garbage receiving position 101, and the garbage unloading position 102 are located at different positions along the linear movement path. In other words, the vibration shaking, garbage receiving, and garbage unloading of the box assembly 4200 can share the same drive assembly 4100, which is conducive to simplifying the structure, improving the compactness of the layout, and reducing costs. It is understandable that the vibration shaking of the box assembly 4200 can also use a separate set of drive assemblies, and the movement of the box assembly 4200 between the garbage receiving position 101 and the garbage unloading position 102 can use another set of drive assemblies separately, and is not limited to sharing the same drive assembly. Furthermore, the trash bin mechanism 4 also includes multiple second detection optocouplers 104, which can be installed on the frame mechanism 1 and correspond to the shaking detection position 103, the garbage receiving position 101 and the garbage unloading position 102 respectively. The second detection optocoupler 104 is used to detect whether the box assembly 4200 has moved into place, which is conducive to automation.

[0045] Optionally, the drive assembly 4100 includes a drive member 4101, which can be a stepper motor, a hydraulic cylinder, a pneumatic cylinder, or other drive member capable of providing power. When the drive member 4101 is a stepper motor, the output end of the stepper motor transmits power to a synchronous belt connected to the box assembly 4200 after a first-stage deceleration. The drive member 4101 drives the box assembly 4200 to move via the synchronous belt; wherein the drive member 4101 and the box assembly 4200 can be connected by a gear rack, and is not limited to the synchronous belt connection mentioned above. As long as it can drive the box assembly 4200 to move and switch between the shaking detection position 103, the garbage receiving position 101, and the garbage unloading position 102, it will be sufficient.

[0046] Optionally, the box assembly 4200 is movably mounted on the frame mechanism 1 via a guide assembly 4500. The guide assembly 4500 is used to guide the movement of the box assembly 4200, which helps to improve the stability of the movement of the box assembly 4200. Furthermore, the guide assembly 4500 includes a guide rail 4501 and a slider 4502. The guide rail 4501 is mounted on the frame mechanism 1. The slider 4502 is fixedly connected to the box assembly 4200 and slidably cooperates with the guide rail 4501. The drive assembly 4100 is connected to the slider 4502 to drive the box assembly 4200 to move along the guide rail 4501 via the slider 4502. Specifically, a synchronous belt is connected to the slider 4502, and the drive member 4101 drives the box assembly 4200 to move by synchronously driving the slider 4502; wherein the slider 4502 can be connected to the outer box 4202 of the box assembly 4200.

[0047] In the trash bin assembly of the above embodiment, the driving assembly 4100 can drive the box assembly 4200 to vibrate back and forth between the shaking detection position 103 and the trash receiving position 101, which can effectively avoid partial stacking of the trash loaded in the inner box 4205 so that the trash is spread flat on the inner box 4205, which is beneficial to improving the trash loading capacity of the inner box 4205 and improving the space utilization rate of the inner box 4205. At the same time, it also reduces the probability of misjudging that the inner box 4205 is fully loaded, thereby improving the reliability of the trash bin device.

[0048] See also Figure 2 、 Figure 4 and Figure 6In some optional embodiments, the trash bin mechanism 4 further includes a front door assembly 4300. The front door assembly 4300 is elastically connected to the box assembly 4200 so as to be relatively movable. The front door assembly 4300 abuts against the frame mechanism 1 and remains stationary when the box assembly 4200 moves between the shaking detection position 103 and the trash receiving position 101. In other words, when the box assembly 4200 oscillates back and forth to shake the trash in the inner box 4205, the front door assembly 4300 abuts against the frame mechanism 1 and remains stationary. The front door assembly 4300 is located at the inlet and outlet side of the frame mechanism 1. The front door assembly 4300 abuts against the inlet and outlet side of the frame mechanism 1, thereby shielding the inlet and outlet of the frame mechanism 1. This allows the front door assembly 4300 to appear to be stationary, making the appearance more neat. It also allows the box assembly 4200 to be located in a relatively closed space, reducing the risk of interference with other components.

[0049] Optionally, the front door assembly 4300 includes a front door panel 4301, which is movably connected to the housing assembly 4200 via a guide structure. The guide structure is used to guide the movement of the front door panel 4301. An elastic member 4303 is connected between the front door panel 4301 and the housing assembly 4200, and can drive the front door panel 4301 to move and return to abutment with the housing assembly 4200. The elastic member 4303 can be a tension spring. When the housing assembly 4200 moves between the shake detection position 103 and the garbage receiving position 101, the front door panel 4301 abuts the frame mechanism 1 to overcome the elastic force of the elastic member 4303 and maintain its position. Furthermore, the guide structure includes a first guide rod 4304 and a first guide sleeve 4307. The first guide sleeve 4307 is mounted on the first guide rod 4304 and connected to the box assembly 4200 or the guide assembly 4500. For example, the first guide sleeve 4307 is connected to the outer box 4202 or the slider 4502, so that the first guide sleeve 4307 and the box assembly 4200 remain stationary. Specifically, a connecting plate 4302 is fixedly mounted on the inner side of the front door panel 4301. One end of the first guide rod 4304 can be connected to the front door panel 4301 via the connecting plate 4302. The other end of the first guide rod 4304 passes through the first guide sleeve 4307 and slides in engagement with the first guide sleeve 4307. One end of the elastic member 4303 can also be connected to the front door panel 4301 via the connecting plate 4302. The other end of the elastic member is connected to the outer box 4202 of the box assembly 4200.

[0050] Optionally, the front door assembly 4300 further includes a support plate 4305, which is mounted on the front door panel 4301 and elastically abuts against the box assembly 4200 under the elastic force of the elastic member 4303. In this embodiment, the support plate 4305 can be connected to the front door panel 4301 via a connecting plate 4302. Furthermore, under the elastic action of the elastic member 4303, the box assembly 4200 and the front door panel 4301 are brought together and restrained by the abutment of the support plate 4305. Specifically, when the box assembly 4200 moves from the garbage receiving position 101 to the garbage unloading position 102, the support plate 4305 is in elastic abutment with the outer box 4202, and the elastic member 4303 is in a stretched state, which facilitates relative stability between the front door panel 4301 and the outer box 4202, allowing the front door panel 4301 and the box assembly 4200 to move together.

[0051] Optionally, the front door assembly 4300 further includes a rubber cushion 4306 mounted on the front door panel 4301 and positioned between the front door panel 4301 and the housing assembly 4200. The rubber cushion 4306 cushions the impact between the front door panel 4301 and the frame mechanism, thereby ensuring a more stable contact between the front door panel 4301 and the frame mechanism 1 and preventing damage to the trash bin assembly. In this embodiment, as the housing assembly 4200 reciprocates between the shake detection position 103 and the trash receiving position 101 to drive the housing assembly 4200 to vibrate and mix the trash, the front door panel 4301 maintains an elastic contact with the frame mechanism 1, and the outer housing 4202 gradually approaches the support plate 4305, abuts against the support plate 4305, and gradually moves away from the support plate 4305, separating from the support plate 4305.

[0052] In the trash bin device of the above embodiment, the front door assembly 4300 and the box body assembly 4200 are movably and elastically connected, so that the front door assembly 4300 can move with the box body assembly 4200, and can also move relative to the box body to provide movement space for the vibration and shaking of the box body assembly 4200. The layout is compact and the structure is simple.

[0053] See also Figure 1 、 Figure 2 and Figure 7 In some optional embodiments, the sealing assembly 4400 includes a power piece 4405 and two oppositely arranged clamps, the power piece 4405 is connected to the clamps and drives the clamps to move to close the bag opening of the garbage bag; one of the two clamps is a high-temperature resistant element, and the other is a heating element that can be heated to hot-melt seal the bag opening of the garbage bag.

[0054] Optionally, the power member 4405 is connected to the two clamping plates via a transmission structure to drive the two clamping plates to move synchronously; the transmission structure includes a bidirectional screw rod 4407 structure or a synchronous belt structure. Furthermore, when the transmission structure is a bidirectional screw rod 4407, the two clamping plates are respectively connected to the ends of the bidirectional screw rod 4407. The bidirectional screw rod 4407 rotates to drive the two clamping plates to move toward each other, toward and away from each other. For example, the bidirectional screw rod 4407 rotates forward to drive the two clamping plates toward each other to clamp the garbage bag so that the bag opening shrinks and closes. The bidirectional screw rod 4407 rotates backward to drive the two clamping plates away from each other to loosen the garbage bag.

[0055] Optionally, there are two bidirectional screw rods 4407, which can be arranged opposite and parallel to each other. The two ends of one bidirectional screw rod 4407 are respectively connected to the front ends of the two clamping plates, and the two ends of the other bidirectional screw rod 4407 are respectively connected to the rear ends of the two clamping plates. This structural layout helps improve the stability of the clamping plate movement. Furthermore, the sealing assembly 4400 also includes a guide wheel 4411 and a tensioning structure 4402. The power member 4405 drives the two bidirectional screw rods 4407 to rotate simultaneously via the toothed synchronous belt 4404 and the guide wheel 4411. The tensioning structure 4402 is connected to the toothed synchronous belt 4404 to adjust the tightness of the toothed synchronous belt 4404.

[0056] Optionally, the sealing assembly 4400 further includes a support structure 4403 , which can provide installation support for components such as the two splints, the tensioning structure 4402 , and the power member 4405 . The support structure 4403 can be connected to the inner box 4205 to install the sealing assembly 4400 on the inner box 4205 .

[0057] Optionally, the sealing assembly 4400 further includes a second guide rod 4408 and a second guide sleeve 4412 . The second guide rod 4408 is mounted on the support structure 4403 . The clamping block is connected to the second guide rod 4408 via the second guide sleeve 4412 to achieve movement and guidance of the clamping block.

[0058] Optionally, the two clamps are a first clamp 4401 and a second clamp 4409, wherein the first clamp 4401 can be a heating element, such as a heating wire, and the second clamp 4409 can be a high-temperature resistant element, such as high-temperature resistant rubber. The hot-melt sealing operation of the bag openings of garbage bags of different thicknesses can be adapted by controlling the heating time of the heating wire and the pressure between the heating wire and the high-temperature resistant rubber. Furthermore, the sealing assembly 4400 also includes a mounting plate, the rear side of the high-temperature resistant rubber is connected to the mounting plate via a spring 4410 and can move with the mounting plate. The high-temperature resistant rubber and the mounting plate are elastically connected by the spring 4410, which facilitates adjusting the clamping pressure between the high-temperature resistant rubber and the heating wire.

[0059] Optionally, the sealing assembly 4400 also includes a third detection optical coupler 4406, which is used to detect whether the two clamps are close together and clamped in place. The third detection optical coupler 4406 can be installed on the support structure 4403. When the third detection optical coupler 4406 detects that the two clamps are close together and clamped in place, the two clamps are tightly attached, and the clamps of the heating element start heating operations to perform hot-melt sealing on the garbage bag.

[0060] In the trash bin device of the above embodiment, the sealing assembly 4400 has a simple structure and high versatility, and can perform sealing operations on trash bags of different types and specifications, thereby improving the versatility of the trash bin device and helping to reduce costs.

[0061] In some optional embodiments, the trash bin device further includes a controller configured to control the operation of the drive assembly 4100 and the power member 4405. The controller may receive signals from the first detection optical coupler 4204, the second detection optical coupler 104, the third detection optical coupler 4406, the reflection detection optical coupler 302, the through-beam detection optical coupler 203, and the pressure sensor 4206, and control the operation of components such as the bin assembly 4200 and the sealing assembly 4400 based on the signals.

[0062] Specifically, the controller determines whether the garbage bag is installed in place and fixed based on the signals of the first detection optocoupler 4204 and the pressure sensor 4206. When the garbage bag is installed in place and fixed, the controller controls the negative pressure fan 4201 to start and controls the drive component 4100 to drive the box component 4200 to move to the garbage receiving position 101. When the reflection detection optocoupler 203 detects that some garbage is thrown into the box component 4200, the controller can control the drive component 4100 to drive the box component 4200 to move between the garbage receiving position 101 and the shaking detection position 103 to shake and mix the garbage, until the reflection detection optocoupler 302 detects that the box component 4200 is full of garbage, the controller controls the sealing component 4400 to seal the garbage bag and controls the drive component 4100 to move the box component 4200 to the garbage unloading position 102.

[0064] Optionally, the sample analyzer further includes a frame, and the frame mechanism is connected to the frame. Garbage generated during the use of the sample analyzer can enter from the inlet 202 of the disposal pipe 201 and be sent to the garbage bag in the box assembly 4200.

[0065] The sample analyzer of the above embodiment collects garbage generated during the operation of the sample analyzer through the garbage bin device, which reduces the exposure of the garbage, thereby helping to reduce the biological contact between the operator and the garbage, and further helping to improve safety performance.

[0066] The trash bin device and sample analyzer of the present invention enable the garbage to be kept in a closed state, reducing contact with the outside world, thereby helping to reduce the spread of pathogens; and the trash bin device can package and seal the garbage bags through the sealing component 4400, and automatically send the garbage bags to the garbage unloading position 102 through the driving component 4100, reducing the contact between the operator and the sample and improving safety.
